Flush opening control with mechanical or electrical ejection and retraction.
The present invention relates to a mechanism for controlling the opening of a motor vehicle. In addition, the invention relates to a motor vehicle opening, for example a door, comprising such an opening control.
In the state of the art, some opening control devices are known with ejection and retraction of the handle between a position flush with the exterior surface of the car body and an ejected position. These opening commands are called “flush” opening commands.
Document FR 3023865 filed by the applicant describes a handle mechanism which is flush with the body of a door provided with an electric actuator which actuates the ejection and retraction of the handle. The actuator can be remotely controlled by the user key or a vehicle computer. This system is very ergonomic but does not work during a power failure.
Document FR 3024173 also filed by the applicant describes a handle mechanism which is flush with the body of a door. The handle is ejected from the door by action when the user presses on the handle. The return to the position flush with the body is also done mechanically by the action of this user when the latter pulls the handle. This system is not dependent on an electrical actuation but is less ergonomic than the previous one.
Document GB 2492231 filed by Jaguar Cars Limited describes an opening control device with electric actuator. In the event of a power failure, the user can tilt the handle to open the door. However, the device does not provide for a device for locking the handle of the vehicle in the parking position, or, in the event of an accident, in order to avoid inadvertent triggering of a lock by the handle. In addition, the mechanical actuation of the device is not ergonomic, the preferred operation being in electrical mode.
The document EP 2 730 730 A2 filed by Aisin Seiki Kabushiki Kaisha describes a flush opening control, "flush", the handle of which operates in a motorized manner with a rotary movement of the handle, and having a means for locking the handle in exit position. However, like the previous device, the device does not provide for a device for locking the vehicle handle in the parking position, or, in the event of an accident, in order to avoid inadvertent release of the lock by the handle. In addition, the mechanical actuation of the device is not ergonomic, the preferred operation being in electrical mode.
Document US 2016/281397 describes a retractable handle system and a mechanism intended to control a movement of the handle from a flush position to an ejection position. The handle is moved by means of an electric drive.
Document US 2016/0222705 A1 describes a set of a handle configured to be flush in the closed position and to protrude in the operating position. The set includes electrically controlled arms for moving the handle between the two positions.

FIG. 1 shows schematically a perspective view of an opening control according to the invention designated by the general reference 10.
The opening control 10 comprises a mechanical part 20 and an electrical part 30. In FIG. 2, the opening control 10 is shown in which the mechanical part 20 and the electric part 30 are separated from one another. other. The opening control 10 also comprises a housing 50 intended to house the electrical 30 and mechanical 20 parts as illustrated in FIGS. 1 and 2.
The opening control 10 conventionally comprises a handle 60 configured for gripping by a user. This handle 60 is movable in rotation relative to the housing 50 between several positions described below with reference to Figures 3A to 3D. There is shown in these figures the main possible positions taken by the handle 60. In Figures 3A to 3D, the opening control 10 is shown assembled on a door 70 of a body of a motor vehicle. The housing 50 is intended to be fixed to the opening 70.
FIG. 3A illustrates the opening control 10 and its handle 60 in a flush position with respect to the bodywork 70 in which the handle 60 is completely or partially housed in the housing 50, that is to say that the external surface of the opening control 10 coincides with the outer surface of the opening 70. This flush or "flush" arrangement, known in the automobile industry, makes it possible to enhance the style of the vehicle and reduces aerodynamic drag.
ίο
In this flush position, the handle 60 of the opening control 10 can be:
either "blocked", that is to say that a mechanical action on the handle 60 will not cause it to be ejected, or "unlocked", and in the latter case a pushing action on the handle 60 will cause it to be ejected as it will be described later.
FIG. 3B illustrates the handle 60 in a position pressed towards the inside of the opening 70. This depression of the handle 60 can lead, in the case where the opening control 10 is released, to a control of the ejection of the handle 60. Otherwise, when the opening control 10 is blocked, the depression of the handle 60 will not cause the ejection of the handle 60. This will be explained in detail below.
FIG. 3C illustrates the handle 60 in the “ejected” position, ready to be grasped by the user to be pulled and thus trigger the opening of the lock and of the door. In the ejected position, the handle 60 is at least partially removed from the housing 50, so that the user can grasp the handle 60 and open the door 70.
FIG. 3D illustrates the handle 60 in the "pulled" position or open position, position corresponding to a release of the lock and to the opening of the door and in which the handle 60 has caused the unlocking of the opening 70.
Furthermore, different operating configurations of the opening control 10 are illustrated diagrammatically in FIG. 4:
the configuration MO corresponds to a configuration in which the handle 60 is in a flush position in accordance with FIG. 3A and locked;
the configuration S corresponds to a configuration in which the handle 60 is in a flush position in accordance with FIG. 3A and unlocked;
the configuration M1 corresponds to a configuration in which the handle 60 is in an ejected position (FIG. 3C); the M2 configuration corresponds to an opening of the door.
The arrows illustrate the various actions (retraction-ejection, blocking-unblocking) to be carried out to switch from one configuration to another which will be detailed below.
The mechanical part 20 will now be described in more detail with reference to FIGS. 5 to 14. FIG. 5 is an exploded view of the mechanical part 20.
In FIG. 6, it can be seen in particular that the handle 60 comprises two parts, an external lever 60a and an internal lever 60b. With reference to this figure, it can be seen that, in a conventional manner, the external lever 60a has a length significantly greater than that of the internal lever 60b, which gives a “leverage effect”, known to those skilled in the art and is configured to allow gripping. As illustrated in FIG. 6, the handle 60 is rotatably mounted around a pivot axis 80 integral with the housing 50.
According to the invention, the opening control 10 also comprises a lever 100 for ejecting the handle 60. As illustrated in FIG. 6, this ejection lever 100 is mounted on the pivot axis 80 of the handle 60. Thus, the lever 100 is connected to the handle 60 by at least one common axis of rotation 80.
The ejection lever 100 is an ejection mechanism and constitutes an essential part of the invention. The ejection lever 100 makes it possible to separate the handle 60 from the mechanisms which control it, which makes it possible to choose between mechanical and electrical operation according to the situation, or according to the preference of the user, and always ergonomically for the user, apart from the case of electrical failure which will be described later. This possibility of using either a mechanical or electrical actuation mode, while preserving the ease of control and use of the opening control constitutes one of the major advantages of the invention. The mechanisms that control the movement of the eject lever will be described later.
The ejection lever 100 will now be described with reference to FIGS. 7 to 11.
In the example illustrated in FIG. 7, the ejection lever 100 has a first cheek 110a and a second cheek 110b, the two cheeks being parallel to each other and perpendicular to the axis of rotation 80. These cheeks 110 are on one side connected by an upper transverse branch 120 intended to come into abutment against the upper surface 62 of the inner lever 60b and on the other hand to a lower transverse branch 130, which is intended to come into abutment against a lower bearing wall 64 of the inner lever 60b visible in FIG. 6.
Preferably, the ejection lever 100 also has two openings 112a and 112b arranged in the cheeks 110a and 110b. These openings 112a and 112b are intended to allow the passage of a set of cams 450 of the electrical part 30 of the opening control 10 which will be described below as well as the cooperation of the ejection lever 100 with this set of cams 450.
This configuration of the ejection lever 100 makes it possible to implement an ejection control, either manual or electric, in the unlocked handle position, as well as the blocking of an ejection control, in the locked handle position, as will be described more far. This particular configuration of the ejection lever 100 is not limiting and those skilled in the art can imagine a different mechanism but performing an equivalent function.
Preferably, the lower transverse branch 130 of the ejection lever 100 is provided with two anti-noise stops 132 made of elastomeric material, the function of which is to dampen the contact noises between the ejection lever 100 and the wall of lower support 64 of the inner lever 60b.
The noise is damped when the internal lever 60b is returned to the ejection lever 100, in particular when the open position is returned to the ejected handle position.
FIG. 6 shows the handle 60 provided with a handle return spring 160 which is placed between the ejection lever 100 and the internal lever 60b of the handle 60 and which have a common axis of rotation 80.
The handle return spring 160 has two legs and a central part. The function of the handle return spring 160 is to maintain contact between the internal lever 60b and the ejection lever 100, or a return force, that is to say to make up a play between these two elements 60b and 100.
The handle return spring 160 is used in two cases:
when the external lever 60a is flush with the body of the car and when the user pushes on the external lever 60a towards the interior of the door (FIG. 3B) to manually control its ejection towards the exterior of the door. The handle return spring 160 is compressed when the external lever 60a is pushed and then brings the handle 60 back into contact with the ejection lever 100 after the external lever 60a is pushed. If the opening command is released at the time of the push, an ejection movement of the ejection lever 100 and of the handle 60 will be consecutive to the push applied by the user. If the opening command is blocked when the handle is pushed, the handle will return to the flush position without ejecting the latter.
when, from the ejected position, after having pulled the external lever 60a towards the outside of the door, in the open position, the user releases the external lever 60a. The handle return spring 160 then creates a return torque which tends to bring the internal lever 60b against the ejection lever 100.
In addition, the opening control 10 also comprises a return member 40 connected to the lever 100. The return member 40 is configured to return the lever 100 to a so-called handle ejection position 60.
This return member 40 preferably comprises an ejection lever spring 40 illustrated in FIG. 5 which is provided with two external tabs and with a central part. We see in Figure 12 the ejection lever spring 40 installed in the housing 50. Each of the two legs is fixed to an inner wall, respectively, of the housing 50. The central part of the spring 40 is intended to push the lever d ejection 100 towards the lower support wall 64 of the handle 60 in order to eject the handle 60.
According to the invention, the opening control 10 also comprises means 450 for pivoting the lever 100 around the common axis of rotation 80 and means 300 for locking the lever 100 in a locking position going against the return force exerted by the return member 40.
According to the invention, the return member 40 is configured to automatically return the lever 100 from its locking position to its ejection position in a direction of ejection rotation when the lever 100 is released from the locking means 300.
The ejection lever 100 also preferably includes a drive member 150 of the locking means 300 and is provided for example with a rocker 150 shown in particular in Figures 7 and 9. The drive member 150 is arranged to cooperate with the pivoting means 450 by a releasable mechanical guide link and to drive the locking means 300 in a position for disengaging the lever 100. A releasable mechanical link is understood to be a connection which is not permanent so that the locking means 300 and the lever 100 do not cooperate mechanically permanently. Preferably, the drive member 150 comprises a rocker 150 rotatably attached to a head 152 connected to the ejection lever 100.
The rocker 150 is in the illustrated example formed by a rotary lever comprising a first arm and a second arm. The rocker 150 is rotatably attached to the head 152 connected to the ejection lever 100, near the lower branch 130 and the first cheek 110a. The head 152 constitutes the axis of rotation of the lever 150. The lever 150 can for example rotate from 15 ° to 45 ° around its axis of rotation.
The ejection lever 100 is, on the side of the second cheek 110b, provided with an upper profile 160 referenced in FIGS. 7 and 11. The upper profile 160 is connected to the upper transverse branch 120, and is transverse to it. this.
In FIG. 10, it can be seen that the ejection lever 100 is preferably provided with a cam axis 170 transverse to the upper profile 160 and parallel to the common axis 80. An ejection lever cam 172 is connected to the cam axis 170 rotatably. The cam of the ejection lever 172 can rotate for example from 5 ° to 15 ° around its axis of rotation 170.
The ejection lever 100 is also provided in this example with an internal profile 180, which is connected to the lower transverse branch 130, and is transverse to this, shown in detail in FIGS. 7 and 10. The lower profile 180 and the cam of the ejection lever 172 are in the same plane shown in FIG. 10.
As shown in detail in Figure 5, the locking means 300 comprise a pawl mechanism. This pawl mechanism has the general reference 300.
The pawl mechanism 300 is shown in detail in FIGS. 13 to 15. This mechanism 300 comprises a pawl axis 310, parallel to the axis of rotation 80 of the ejection lever 100. This mechanism 300 comprises a first pawl 320 of ejection lever 100 subjected to an elastic return which urges it into a position in engagement with the lever 100.
The first pawl 320, designated by the ejection lever pawl, is provided with a first torsion spring 322. The function of the ejection lever pawl 320 is to block the rotation of the ejection lever 100, and therefore to block the ejection of the handle 60. Indeed, as can be seen in FIG. 14, the first pawl 320 is arranged to move between a first position in which the first pawl 320 engages with the ejection lever 100 and blocks the ejection of the ejection lever 100 and a second position in which the first pawl 320 is no longer engaged with the ejection lever 100.
The mechanism 300 further comprises a second pawl 330, designated by handle locking pawl which is provided for example with a second torsion spring 332. This handle locking pawl 330 is subjected to an elastic return which urges it into a position in engagement with the handle 60.
As can be seen in Figures 15A and 15B, the second pawl 330 is arranged to move between a first position in which the pawl 330 engages the inner lever 60b of the handle 60 and blocks the ejection of the handle 60 and a second position in which the second pawl 330 is no longer engaged with the internal lever 60b.
Preferably, the pawls 320 and 330 are arranged on a common axis so that the lever pawl 320 is capable of blocking the lever 100 while the blocking pawl 330 is not engaged with the handle 60.
To this end, the handle locking pawl 330 is also provided with a transverse branch 334 (FIGS. 13A and 13B), which abuts against the pawl of the ejection lever 320. The second torsion spring 332 is wound around of the pawl pin 310 and is in contact with the branch 334, and drives the handle locking pawl 330 towards the pawl of the ejection lever 320 in the counterclockwise direction defined according to FIG. 13B.
The opening control 10 also preferably comprises a pawl retention lever 340 which is positioned opposite the pawl of the ejection lever 320 and is provided with a return spring called the retention lever spring 342 (FIG. 16A or 16B). This lever 340 is illustrated in detail in FIGS. 16A and 16B. This retention lever 340 is configured to retain the lever pawl 320 in the released position of the lever 100 against the return force of the lever pawl 320.
As can be seen in FIG. 16B, the pawl retention lever 340 blocks the rotation movement of the pawl of the ejection lever 320 counterclockwise which in turn blocks the movement of the handle blocking pawl 330 and this fact, the ejection lever 100 can rotate freely in rotation without interfering with the pawl of the ejection lever 320. As a result, the handle locking pawl 330 is locked in the counterclockwise direction defined according to FIG. 13B by the ratchet lever 320.
FIG. 16A shows a position in which the pawl retention lever 340 does not block the pawl of the ejection lever 320, which then blocks the ejection lever 100, as can be seen in an illustration in FIG. 14. The pawl handle locking lever 330, locked by the ratchet of the ejection lever 320 counterclockwise, will specifically block the inner lever 60b (see FIG. 15B) and consequently will block the rotation of the handle 60.
The reason for the separation of the rotational blockages with two distinct elements 320 and 330 will be explained below.
In the handle locking position 60, the handle locking pawl 330 abuts against the internal lever 60b and blocks the rotation of the handle 60 clockwise according to FIG. 15B, that is to say prevents any ejection of the handle 60 towards the outside of the door.
The function of the handle locking pawl 330 is to prevent the ejection of the handle 60 by the action of inertia from a violent shock, or from an accident, or, for example, by rebounding of the handle during a loud door slam. Thus, inadvertent release of the door lock because of the ejection of the handle is impossible, in particular during an accident, which greatly contributes to the security provided by the device according to the invention.
A specific function and purpose of the handle locking pawl 330, which is a separate part from the pawl of the eject lever 320, and which has a possibility of rotation relative to the pawl of the eject lever 320, is that , if the user keeps in hand the handle 60 in the ejected position while the vehicle is to be locked, then this movement of rotation independent of the pawl of the ejection lever 320 still allows the locking of the door lock. The pawl of the ejection lever 320 can thus block the rotation of the ejection lever 100, independently of the pawl 330, and the opening of the door is blocked, even if the handle 60 has remained in an ejected position, retained by the user's hand. Thus, the user can no longer open the door by exerting a rotation of the handle, the door opening is blocked regardless of the position taken out of the handle.
In FIGS. 5, 17A to 18, there is also shown a return mechanism 200 comprising a return lever 210 which rotates integral with a return axis 212 and which is recalled by a return spring 214. A Bowden cable (not shown) is used as usual on this type of mechanism to actuate the lock and open the door. The return axis 212 is provided with a cam 220.
The end of the cable is generally attached to the return and the cable sheath is fixed to the housing 50. When the lever 60a and the ejection lever 100, which have a common axis 80, are in the ejected position, an interaction is possible between the internal lever 60b and the cam 220 on the return axis 212, which rotates integral with the return lever 210.
During the pulling of the lever 60a by the user to the door open position, the action on the cam 220 rotates the return lever 210. The rotation of the return lever 210 causes the Bowden cable to be pulled and thereby opening the door lock. Note that traction on the Bowden cable is only possible, according to the invention, if the ejection lever 100 is in the ejected position.
The electric part 30 of the opening control 10 according to the invention will now be described with reference to FIGS. 19 to 22. The electric part 30 forms an electric actuator 30 of the opening control 10 and comprises an electric control mechanism designated by the general reference 400. According to the invention, the electric actuator 30 is connected to the pivoting means 450 for electrically moving the lever 100 between at least locking and handle ejection positions in an electric operating mode.
The electrical part 30 comprises a housing 402 and the control mechanism 400 is housed in the housing 402. The housing 402 is connected to a cover 404 by screws 406, but other means of mechanical union can be used. Preferably, the housing 402 and the cover 404 define a sealed interior volume.
The electrical mechanism 400 comprises in this example a control wheel 410, a toothed wheel 412, a control wheel 414, a worm 416 as well as a transmission wheel 418. The control wheel 410 is intended to be driven by the transmission wheel 418, itself driven by the endless screw 416 which is rotated by an actuating motor 420 as can be seen in FIG. 19.
The actuation motor 420 is connected to an electronic card 430 by overmolded electrical connection tracks 432 or other electrical connection means. The electronic card 430 is a component of the opening control 10 and is itself connected to a computer of the vehicle not shown. The actuation motor 420 is controlled by the electronic card 430.
The control wheel 410 has three operating positions corresponding to the illustrated configurations MO, S and Ml of FIG. 4 and the various movements of the electrically controlled handle can be made between these three operating positions.
In a preferred embodiment of the invention, the actuation motor 420 is connected to the control wheel 410 by the worm screw 416 and the transmission wheel 418. The actuation motor 420 controls the control wheel 410 which in turn positions the ejection lever 100 by means of a set of cams 450 described below (FIG. 20) which cooperate respectively with the interior 180 and exterior 160 profiles of the ejection lever 100 and with the cam of the ejection lever 172, so as to impart a rotational movement of the ejection lever 100 about its axis of rotation 80.
A person skilled in the art understands that the transmission between the engine and the ejection lever 100 can be carried out in several ways (bevel gears, planetary, helical, articulated levers, etc.). Furthermore, the invention could include any type of linear or rotary electrical actuation (brushed motors, brushless motors, stepper motors, solenoid, piezo motors, jacks, etc.).
Depending on the request from the vehicle computer, the actuating motor 420 can position the control wheel 410 in three positions corresponding to the three configurations S, Ml or MO in order to eject, retract or block the handle so electric.
In order to obtain this type of operation, the actuation motor 420 is preferably controlled by pulse width modulation (PWM) in order to obtain an adequate speed of rotation to obtain a controlled positioning and which provides a sound sensation and visual pleasant to the user.
The control wheel 410 is preferably able to rotate integrally with the control wheel 414, linked in rotation by a flat 416 or any other rotary drive system. The outer surface of the control wheel 414 has on its periphery surfaces more or less radially distant from the axis of the wheel and which allow indexing of the three positions corresponding to the operating configurations S, MO and Ml.
According to the invention, the lever 100 and the pivoting means 450 are able to cooperate mechanically to disengage the lever 100 from the locking means 300 and cause the automatic return of the lever 100 to its ejection position, both in a mode of manual operation by depressing the handle 60 from its flush position to cause the ejection lever 100 to rotate in a direction opposite to the direction of ejection rotation as in the electric mode by electric rotation of the pivot means 450 by l electric actuator 30.
Preferably, the pivoting means 450 comprise a cam assembly 450 comprising at least one cam.
This cam assembly 450 comprises a cam axis 452 on which are preferably mounted integrally the control wheel 410, the toothed wheel 412 and the control wheel 414. The cam assembly 450 in this example comprises three cams:
a first cam 450a, called the ejection cam, located from the end of the cam axis 452,
- then thereafter, at a respectively increasing distance from this end, a second cam 450b, called a retraction cam, and
- A third cam 450c, called the clutch cam, (Figure 20).
These three cams 450a, 450b, 450c are axially separated and have different shapes and radial dimensions. The rotation of the cam axis 452 simultaneously displaces the three cams, which will act on the ejection lever 100 as described below. The cam assembly 450 is intended to be inserted inside the ejection lever 100 through the openings of the ejection lever 100 as well as through the interior lever 60b.
The first cam 450a is located substantially at one end of the cam axis 450 and has a radius less than or equal to the radius of the cam axis
452. It can be seen in particular in FIGS. 23A to 23D that the first cam 450a is intended to be in the same plane as the rocker 150 and that the pawl of the ejection lever 320. Preferably, the ejection cam 450a is movable in rotation relative to the housing 50 around the cam axis 452 and has a guide surface configured to releasably cooperate with the lever 100 by guiding the drive member 150 against the ejection cam 450a.
Preferably, the lever 100 is the pivoting means 450 include disengageable mechanical coupling means. These disengageable mechanical coupling means comprise, in the example described, the drive member 150 and the ejection cam 450a. Thanks to these disengageable means, the opening control 10 is capable of adopting a flush-locked handle configuration MO in which the mechanical coupling is disengaged, a flush-unlocked handle configuration S in which the mechanical coupling is engaged and an ejected handle configuration Ml. Preferably, the transition from one configuration to another is possible in electric mode and / or in manual mode. In the disengaged state, manual pushing action on the handle 60 cannot cause the handle to be ejected. The ejection of the handle is thus blocked. In the engaged state, the handle can however be ejected by simple manual push.
Thus, preferably, in the configuration MO, the member 150 and the cam 450a are sufficiently spaced from one another to prevent the disengagement of the lever 100 by depressing the handle 60 and in the flush-unlocked configuration, the the member 150 and the cam 450a are sufficiently close to one another to allow the lever 100 to disengage by depressing the handle 60.
The second cam 450b, called the retraction cam is in this example movable around the cam axis 452 and has a guide surface configured to pivot the lever 100 from the ejection position to the locking position in the mode of electrical operation.
Furthermore, the guide surface of the retraction cam 450b is also configured to guide in force, against an obstruction of the automatic return of the lever 100 to the ejection position, for example linked to the gel, the ejection of the handle 60 by electrical actuation of the cam 450b in the opposite direction to the direction of retraction.
Furthermore, in the example described, the clutch cam 450c is also movable around the cam axis 452. The cam 450c is connected to the actuator 30 and has a guide surface shaped to cooperate with the internal profile. 160 of lever 100 to position it in configuration S from, for example, configuration MO.
In addition, the internal profile 160 is shaped so that the clutch cam cooperates with this profile 160 to control the automatic return movement of the lever 100 in its ejection position.
In addition, the electrical mechanism 400 comprises two microswitches 460a and 460b in mechanical contact with the control wheel 414 which are adapted to detect the rotational position of the cam axis 452 and therefore the position of the cams 450a, 450b and 450c . The two microswitches 460a and 460b, distant from each other, are in contact with the control wheel 414 and electrically connected to the electronic card 430 (FIG. 19) of the opening control 10 according to the invention. A person skilled in the art knows the operating principle of this type of microswitch.
The microswitches 460a and 460b transmit the information on their actuation state to the electronic card 430, which if an order is given by the computer, gives an instruction to the motor, which then, according to the order received, stops the movement of the wheel 410 when the cams 450a, 450b and 450c are in predefined positions.
Another microswitch 460c for opening order detection, fixed on the cover 404 (FIG. 2) is activated by the end of the internal lever 60b when, from the flush position (FIG. 27A), the user exerts a thrust F on the external lever 60a partially shown, towards the inside of the door and rotates the handle counterclockwise around its axis 80 (FIG. 27B). This microswitch 460c for opening order detection is connected to the electronic card 430 of the opening control 10 according to the invention. It is also possible to place a microswitch so that it is accessible from the outside, so the user can activate it by touching it and thus control the ejection of the handle, like a button pusher.
In the example described, the two microswitches 460a and 460b operate as follows:
MO configuration, the two microswitches are deactivated and the 430 electronic board is informed that the handle is flush and locked;
Ml configuration, only one of the microswitches is activated and the electronic card 430 is informed that the lever 60a is ejected; configuration S, the two microswitches 460a, 460b are activated and the electronic card 430 is informed that a handle ejection 60 is possible.
In the MO configuration, the control wheel 410 is in a first position, the two microswitches 460a, 460b are deactivated and the electronic card 430 is informed that the handle is flush with the body and that it is blocked. The MO configuration corresponds to a handle which is flush with the body and blocked for an unauthorized person, when the car is parked, or in the process of rolling, or in order to avoid inadvertent opening of the door. If the control wheel 410 is in this first position and the user presses the external lever 60a, the external lever 60a remains stationary.
In the Ml configuration corresponding to a handle in the ejected position (FIG. 3C), the control wheel 410 is in a second position, one of the microswitches 460a, 460b is activated, the other is inactivated, and the electronic card 430 is informed that the lever 60a is in the ejected position.
Once the external lever 60a in the ejected position (FIG. 3C), the user can grasp it and continue the rotation of the lever towards the outside of the door (FIG. 3D) to the "door opening" position in order to unlock the lock to open the door. From this last position of the external lever, when the user releases the external lever 60a, the latter returns to the ejection position (FIG. 3C).
When the control wheel 410 is in the third position corresponding to the configuration S, the two microswitches 460a, 460b are activated and the electronic card 430 is informed that an ejection of the handle is possible. Position S corresponds to the handle flush with the body and in which the user can activate the ejection of the handle either:
by a manual pushing action F of the lever 60a towards the interior of the door which will actuate the microswitch for opening order detection 460c. Thus, when the user presses on the external lever 60a, the external lever 60a slightly returns to its housing (FIGS. 3B and 27B), that is to say up to the “pushed lever” or “push” position, the opening detection microswitch 460c is actuated and then triggers an ejection mechanism which moves the lever 60a out of its housing 50.
either by an order sent to the vehicle computer by a remote control.
The return of the ejected configuration Ml to the non-blocked flush configuration S, that is to say the "retraction" can be done:
either manually by pushing the handle by the user to the non-locked flush position S which engages the blocking of the ejection lever 100, or via a rotation of the cam axis controlled by an order sent by the computer of the vehicle to position S or MO depending on the order sent. This retraction can be provided in various ways, either, for example, via an order given by a remote control, or after reaching a predefined driving speed, for example seven kilometers per hour, or after a given predefined time, by example twenty seconds after the start of ejection.
Taking into account the possibilities of the invention, one could, for example, favor the operation between the configurations MO and Ml, that is to say an electrical ejection and retraction, and reserve the mode S, which allows a purely mechanical ejection , when the vehicle computer detects a low battery.
We will now describe in more detail the operation of the cam assembly 450 with reference to FIGS. 23A to 25B. Figure 23A illustrates the configuration S, Figure 23C illustrates the configuration MI and Figure 23D illustrates the configuration MO. Figure 23B illustrates a transient operating configuration.
With reference to FIGS. 23A to 23D, the function of the first cam 450a is to drive the rocker 150 in rotation, which then releases the pawl from the ejection lever 320, which in turn releases the ejection lever 100 and allows thus unlocking the handle 60.
This rotary drive of the rocker 150 can be achieved in two ways starting from the configuration S illustrated in FIG. 23A:
either by pushing the user on the lever 60a towards the inside of the door, which will thus make the handle rotate counterclockwise and thus bring the lever 150 closer to the cam 450a and rotate the lever 150;
either by an electrically activated rotation of the control wheel 410 and of the cam axis 452, clockwise according to FIG. 23A and which will then cause pivoting of the rocker 150 (FIG. 23B), a release of the pawl of the ejection lever 320 and a rotation of the ejection lever 100 and the lever
60a counterclockwise to an ejected position from the handle, that is to say the configuration Ml of FIG. 23C.
In the MO configuration (FIG. 23D), it will be noted that the distance between the cam 450a and the lever 150 is too great for a manual push on the handle to cause the lever 150 to pivot, which therefore makes it impossible to eject the handle. . In this example, this configuration MO corresponds to the disengaged state of the disengageable coupling means.
When the action tending to pivot the rocker 150 ceases, the first torsion spring 322 tends to return the pawl of the ejection lever 320 to its rest position, but the pawl retention lever 340 blocks the return of the pawl of the ejection lever 320, thus allowing the free rotation of the ejection lever 100 and of the lever 60a towards an ejected handle position. The handle locking pawl 330 will likewise be retained, since its transverse branch 334 is blocked counterclockwise by the pawl of the ejection lever 320 (FIGS. 13A, 13B, 16A and 16B).
Referring now to Figures 24A to 24C, we will describe the operation of the second cam 450b. FIG. 24A illustrates a configuration MO, FIG. 24B illustrates a configuration S and FIG. 24C illustrates a configuration M1.
In the example, the second cam 450b is in an axial position intermediate between the cam 450a and the cam 450c on the cam axis 452 and its radial dimensions are greater than those of the first cam 450a.
In FIG. 24A, the control wheel 410 is in the MO configuration, the second cam 450b is in the same plane as the cam of the ejection lever 172 and that the internal profile 210 of the ejection lever 100.
The cam of the ejection lever 172 is a rotary cam about the axis
170, from 5 ° to 15 °, and which is intended to cooperate with the second cam 450b of the control wheel 410.
When the cam 450b is rotated clockwise according to FIG. 24A for the transition from the configuration MO (flush-locked) to configuration S (flush-unlocked), the shape of the cam 450b, that of the cam of the ejection lever 172, and the freedom in rotation of the cam of the ejection lever 172 allows the free movement of the control wheel 410 from the MO configuration to the S configuration, without however triggering the ejection of the ejection 100. It is the same to go from the configuration S to the configuration MO, by a rotation in a counterclockwise direction, the second cam 450b will rotate freely without driving the cam of the ejection lever 172.
On the other hand, to go from the configuration M1 ejected to the configuration MO (retraction and blocking), passing through configuration S, the second cam 450b will drive the cam of the ejection lever 172, and move the ejection lever 100 by rotating it counterclockwise and thus allowing the ejection lever 100 to be blocked by the pawl 320, the handle 60 also rotates counterclockwise until it is retained by the handle blocking pawl 330 (FIGS. 24C and 24A).
The lower profile 180 has the function of controlling the transition from the configuration S (FIG. 24B) to the position M1 (FIG. 24C). Indeed, after the release of the pawl from the ejection lever 320, by the pivoting of the rocker 150, itself actuated by the rotation of the cam 450a, the spring of the ejection lever 160 pushes the ejection lever 100 towards the lower bearing wall 64 of the external lever 60a and drives the ejection lever 100 and the handle 60 in a clockwise rotation, until an ejected configuration Ml.
The second cam 450b has two functions:
Force the ejection in the case where there are obstacles to the ejection which is carried out by the spring of the ejection lever (for example gel) when the control wheel 410 therefore changes from configuration S to configuration Ml ;
Carry out the retraction of the ejection lever 100 when the control wheel 410 changes from the configuration M1 to the configuration S or MO, by a reverse movement of the cam 450b, in the counterclockwise direction according to FIG. 24C.
Referring now to Figures 25A to 25B, we will describe the operation of the third cam 450c. Figure 25A illustrates a MO configuration.
The third cam 450c is in the position furthest from the end of the cam axis 452, near the toothed wheel 169, and its largest radius is greater than that of the first cam 450a and that of the second cam 450b.
In FIG. 25A, it can be seen that the third cam 450c of the control wheel 410 and the upper profile 160 of the ejection lever 100 are in the same plane.
When the control wheel 410 changes from the configuration MO to Ml, and therefore rotates clockwise according to FIG. 25A, the third cam 450c has the function of first slightly moving the ejection lever 100 in the opposite direction to ejection in order to allow the rocker 150 (FIGS. 25B and 23B) to approach the pawl of the ejection lever 320, to trigger the pawl of the ejection lever 320 and to accompany the ejection of the lever ejection 100 at a controlled and user-friendly output speed.
If the vehicle suffers from an electrical failure when the control wheel 410 is in the first position of the MO configuration, the control wheel 410 cannot be moved and the user will not have access to the automobile.
In order to solve this problem, the opening control 10 according to the invention is provided with an unlocking mechanism 500 illustrated by FIGS. 22 and 26. FIG. 5 shows a latch cover 502, that is to say a cover that hides a lock and / or a pull tab. In the event of a power failure, when the control wheel 410 indicates the locked position MO, the user must use a pull tab or a tool (not shown) to actuate the release mechanism by inserting this tool, for example, in a space provided for this purpose between the opening control and the body. The zipper can be hidden, under the false lock 502 but other options are also possible, for example, it is possible to connect this zipper to a mechanism which is activated when the user turns the key in the lock of the lock. vehicle door, not shown, and which is here located under the latch cover 502, and whose location 504 can be seen in FIG. 5.
It is also possible to make the pull tab accessible in a space provided between the handle and the body.
Referring to Figures 22 and 26, the release mechanism 500 comprises a safety opening lever 510, a safety opening finger 520, a safety opening finger spring 522 and a spring of the opening lever 512 safety lever. The safety opening lever 510 is connected to the handle 60 via its axis of rotation 514.
The safety opening finger 520 is connected to the safety opening lever 510, by its axis of rotation 524. When the user actuates the safety opening lever 510 by pivoting it around its axis of rotation 514 , the latter drives the safety opening finger 520 which then cooperates with the toothed wheel 412 which has the same axis 452 as the control wheel 410, and causes the control wheel 410 to rotate in order to remove it from the position of MO blocking. Optionally, the user will have to repeat the unlocking action several times until sufficient angular rotation is obtained to be able to unlock the ejection of the ejection lever 100.
A person skilled in the art understands that the release mechanism can be designed otherwise, provided that it functions during a power failure, and be arranged in such a way that the user of the vehicle can operate it from outside of the vehicle.
The external lever 60a according to the invention is provided with a damping mechanism 90 connected to the housing and illustrated in FIG. 5. This mechanism 90 comprises a stop body 92, an elastomer stop 94 and a stop spring 96. This spring 96 acts on the handle in the direction of ejection. The spring 96 then pushes on the stop body 92, which is provided with the elastomer stop 94, the function of which is to press the lever 60a.
A first function of this mechanism is, in the event of rolling, vibration or abrupt closing of the door, to prevent the lever 60a from being moved towards the direction of activation and release of the ejection lever 100. A second function is the precise angular adjustment of the position of the lever 60a flush with the body, that is to say the adjustment of the flush, which is carried out by a screwing between the stop 94 and the stop body 92. A third function is the damping of the return of the handle at the end of retraction.
The description below explains the main aspects of both mechanical and electrical operation of the opening control 10 according to the invention. We can in particular refer to the general operating diagram of FIG. 4.
When the lever 60a is in configuration S (flush flush) the user can cause the handle to be ejected (configuration Ml) either:
by pressing on this lever 60a, by pushing it slightly towards the inside of the door which activates the microswitch 460c and gives the order to eject to the computer, by sending an order to the computer via a remote control, in the event of a breakdown electric, by exerting a strong push on the handle lever which will disengage the pawl of the ejection lever 320 and release the ejection lever 100.
In the three preceding cases, the cam 450a is brought into contact with the rocker 150 and makes it pivot, thus causing the rotation of the retention pawl of the ejection lever 320 and therefore the release of the rotation of the ejection lever 100 and of the handle 60a around the axis of rotation 80 and which are driven in rotation towards the outside of the door under the action of the ejection spring 40 (FIG. 23C).
In fact, when the ejection lever 100 is released, the spring 40 of the ejection lever 100 rotates it. The ejection lever 100 and the lever 60a then rotate together around the common axis 80, being in contact via the anti-noise stops 132 placed on the lower branch 130 of the ejection lever 100.
When the external lever 60a is ejected (FIG. 3C), the user can grasp the external lever 60a, and continue the rotation of the lever 60a to release the lock and open the door (configuration M2).
When the user pulls the external lever 60a to unlock the lock and open the door, the ejection lever 100 remains stationary, because the upper branch 120 connecting the two cheeks 110a and 110b is locked in abutment against the housing 50. The lever 60a then rotates around the common axis 80 against the action of the handle return spring 160 either to the open position and the user can open the door (Figures 3D and 17B).
When the user has opened the door, he releases the external lever 60a. At this moment, the handle return spring 160 rotates the lever 60a until its lower bearing wall 64 rests again against the lower branch 130 of the ejection lever 100 and against the anti-noise stop (s) 132 , and closes the space between these two elements, returning to the position Ml ejected handle.
The transition from the Ml ejected configuration to the flush-unlocked S configuration, i.e. a retraction, can then be done:
either by a rotation of the control wheel 410 on a command from the computer, or by a simple manual push exerted by the user bringing the handle to the flush position.
When the control wheel 410 is in the MO configuration, the external lever 60a is flush with the body and is locked. If the user presses the lever 60a, the latter pushes the ejection lever 100 via the anti-noise stops 132. The ejection lever 100 rotates counterclockwise (FIG. 27B). But in this position, as shown in FIG. 23D, there is no possible contact between the cam 450a and the rocker 150.
In fact, in this case, the rocker 150 cannot move the pawl of the ejection lever 320 which keeps the ejection lever 100 blocked. Therefore, the ejection lever 100 is not ejected. The locking function in MO configuration can be used when the vehicle is parked or traveling at a speed higher than a predetermined value, for example seven kilometers per hour. The car computer, which is connected to the gearbox and to the electronic card 430, sends a message to the electronic card 430, which gives an order to the engine to turn the control wheel 320 to the locked flush MO position. . The first cam 450a linked to the control wheel 410 is then moved away from the lever 150 and therefore the pawl of the ejection lever 320 and the pawl of the handle 330 remain in the blocking position and block the lever. eject 100 and the handle 60 which cannot be ejected.
The transition from the blocked MO configuration to the unlocked S configuration, and vice-versa, is done by the already described rotations of the control axis. The transition from MO to S can also be done manually in the event of a power failure.
According to the invention, the user therefore has the possibility of issuing an order to eject the handle via a push exerted manually as previously, but also via a remote control (via a mobile phone, a key, etc.). ). In this case the ejection (or blocking) order passes first to the car computer, which transmits this order to the electronic card 430 of the opening command according to the invention, and which itself give the order to activate the motor 420, then causing the ejection of the handle according to a process which will be described later.
A possible variant embodiment of the invention is to hide the latch directly under the external lever 60a, without latch cover 911, or alternatively to have a visible latch on the flush handle door and disposed near the external lever 60a, finally a last possibility would be an opening command according to the invention, without lock.
Another alternative embodiment of the invention is to install and fix the electrical part 30 not only on one side as shown in FIGS. 1 and 2, but on several sides, for example on either side of the housing 50 Any other implantation of the electrical part 30 is also possible, such as for example a 180 ° rotation of the electrical part 30 around the cam axis 420.
A variant consists of two sets of cams 450a, 450b, 450c placed on each side of the ejection lever with a common transmission shaft in order to make the opening control symmetrical. The purpose of this symmetrical arrangement is to reduce the torsion and bending to which the cam axis is subjected. Thus, the life of the mechanism is increased. A similar effect could be obtained by guiding the end of the cam axis in rotation in the housing 50.
A person skilled in the art understands that the positioning detection means comprising microswitches can be replaced by means comprising a Hall effect sensor, a capacitive sensor, or any other detection means fulfilling the same function.
A person skilled in the art understands that the electrical part and the mechanical part can be located in several ways relative to one another.
The opening control may include means for removing the handle with a mechanism connected to the lock by turning the key in the car lock.
A person skilled in the art understands that the main module can be produced with different types of reduction motors, for example a planetary reduction motor, worm reduction motor, spur reduction motor, bevel reduction motors.
