Title of the invention: Opening command with linear actuator for a motor vehicle.
Technical area.
The present invention relates to the technical field of opening controls for a motor vehicle. The invention relates more particularly, but not exclusively, to an exterior opening control which comprises mechanical unlocking means. Generally, an exterior opening control comprises a fixed support intended to be mounted on the leaf and a handle. movable mounted on the support, for example pivotally mounted on the support while being articulated in rotation about an axis.
The opening control also includes an unlocking mechanism, which when the handle is operated in traction, allows the unlocking of the lock and thus the opening of the door. The lock conventionally comprises a bolt secured to the door capable of cooperating with a keeper secured to the body. When the door is opened from outside the vehicle, the latch is released from the strike by actuation of the exterior opening control.
The invention relates more particularly to an opening control handle of the type "flush", that is to say that the support on which the handle is movably mounted forms a cavity capable of receiving the handle in the retracted configuration . In this retracted configuration, the exterior surface of the handle is flush with the exterior surface of the exterior wall of the opening. In the extended or deployed configuration, the handle at least partially exits the support cavity so that it can be grasped by a user of the vehicle in order to open the door. To do this, the user can move the handle further outward to control the door lock.
In general, the opening control comprises an electric ejection mechanism of the handle to allow the grip of the handle by the user and thus the opening of the opening. The electric ejection mechanism operates from a power supply supplied for example by a battery of the motor vehicle and can be controlled electronically remotely by means of a key, a mobile phone or any other device allowing remote communication.
Prior art.
Already known from the prior art, in particular from patent application EP 3 255 231 A1, a handle of a motor vehicle configured to cooperate with a locking mechanism and movable between a flush position, an ejected position and a position opening in which the gripping element cooperates with the locking mechanism [0007] [0008] [0009] [0010] [0011] [0012] to activate the locking mechanism and to unlock the door. To actuate the ejection electrically, a drive mechanism rotates along an axis of drive rotation and drives an actuator lever cooperating with the handle. The drive mechanism further includes a clutch system to allow the handle to move from the ejected position to the flush position.
The disadvantage of such a handle driving mechanism is the need to use a clutch system to move the handle from the ejected position to the flush position.
In particular, in the case of the use of an emergency mechanism in the event of failure of the electric drive mechanism, it is necessary to provide declutching means which makes the opening control complex and more expensive. Summary of the invention
To this end, the subject of the invention is a command to open a motor vehicle opening of the type comprising:
- a housing intended to be mounted on the opening,
- a handle mounted tilting about an axis relative to the housing between at least one rest position and an ejected position in which the handle is at least partially removed from the housing,
- a pivot lever for the ejection and / or retraction handle and means for electrically actuating the pivot lever,
- characterized in that the lever is configured to pivot about an axis common to the handle and comprises an elastic return member in a return position in which it is able to retain the handle in its rest position and in that the actuating means are configured to pivot the lever against the return force of the return member so as to cause the handle in its rotary movement from its rest position to its ejected position.
Thanks to the invention, the electric actuator cooperates with an elastically recalled ejection lever. In the event of an electrical fault, the lever can remain stationary in its rest position to allow movement of the handle independently of the lever and thus allow actuation of the emergency mechanism.
An opening command according to the invention may also include one or more of the following characteristics.
In another embodiment of the invention, the underside of the handle comprises a shoulder delimiting a transverse support wall from which the internal branch extends axially and against which the lever comes to bear to pivot the handle .
In another embodiment of the invention, the lever has a stirrup shape inside which is engaged an internal branch of the handle and comprising at least one lower transverse connecting bar capable of cooperating with the internal branch.
In another embodiment of the invention, the stirrup comprises a stirrup head extending above an upper face of the handle and a stirrup floor formed by the lower bar coming to take pressing against a lower face of the handle.
In another embodiment of the invention, the stirrup has a general arch shape frontally connecting the head and the floor by two arched side arms.
In another embodiment of the invention, the head and the floor are preferably connected together by two bent side branches at the top of which the stirrup is articulated.
In another embodiment of the invention, the lever comprises a hinge support provided with two bearings for guiding the lever in rotation about the axis Al.
In another embodiment of the invention, the electrical actuation means comprise an ejection arm extending in a direction transverse to the handle to press against the lever and cause it to pivot against the restoring force.
In another embodiment of the invention, the ejection arm is pivotally mounted at one of its ends between two flanges of the housing of the opening control.
In another embodiment of the invention, the electrical actuation means comprise a linear actuator connected to the ejection arm, électriqueelectric actuator comprising a linear actuator provided with one end cooperating with one end of the arm eject to rotate the eject arm around a vertical axis.
In another embodiment of the invention, the handle is configured to pivot freely inside the lever when the lever is stationary, against a handle return spring within the limit of a predefined angular clearance play inside the lever.

Description of the embodiments [0031] FIGS. 1 and 2 show schematically a command to open a door leaf of a motor vehicle according to a first embodiment of the invention. The opening command is designated by the general reference 10.
The opening control 10 is intended to be mounted on an exterior panel (not shown) of the bodywork of an opening which is for example a vehicle side door.
The opening control 10 comprises for example essentially a fixed support or housing 12 having a cavity 14 for receiving a handle and a handle 16 movably mounted inside the cavity 14. In service, the support 12 is intended to be fixed to the opening. The handle 16 is, in the example described, mounted articulated with respect to the panel, about a geometric pivot axis Al, on the support 12. The pivot axis Al is in the substantially vertical service position and extends parallel to the general plane of the exterior panel.
In the example illustrated, the support 12 has a generally parallelepiped shape and is adapted to be housed in a cutout or recess in the outer panel of the opening so that its outer face is flush with the surface of the outer panel. opening. The support 12 is moreover, in this example open from the side of its outer face and delimits the cavity 14 intended to house the handle 16.
The handle 16 is shown in detail in Figure 2. In the example described, the handle 16 has an external portion 16.1 that the user can grasp and unlike the external portion 16.1, the handle 16 has a portion internal 16.2 which is intended to extend inside the housing 14 of the housing 12. In a conventional and nonlimiting manner, on the external portion 16.1, the handle 16 includes a gripping pallet 18, which generally has a flat shape and elongate.
In the example described, the handle 16 is of the "flush" type, that is to say that the cavity 14 of the support 12 is dimensioned to receive the handle 16 in a retracted configuration. In this retracted configuration, the outer surface 16E of the handle 16 is flush with the outer surface of the outer wall of the opening. In the extended or deployed configuration, the handle 16 at least partially exits the cavity 14 of the support 12 so that it can be grasped by a user of the vehicle in order to open the door. To do this, the user can move the handle 16 in traction further outwards in order to control the door lock. In the flush position, the exterior surface of the opening control 10 coincides with the exterior surface of the opening. This flush arrangement, known in the automotive industry, enhances the style of the vehicle and reduces aerodynamic drag.
It is understood, however, that other mobile assemblies can be envisaged, such as in particular for pivoting along an axis located in another position or in translation in a direction essentially perpendicular to the mean plane of the door. It should also be noted that the mobile mounting of the handle relative to the support is known per se to the skilled person.
In this example, the opening control 10 is intended to cooperate with a lock (not shown) of the opening of the motor vehicle capable of adopting a locked configuration and an unlocked configuration. Conventionally, the pivoting of the handle 16 around its articulation axis A1 actuates the lock in one or other of its two configurations locked or unlocked by means of a drive kinematic chain (not shown in the figures).
To this end, as illustrated in Figures 1 and 2, the opening control 10 preferably comprises a return lever 20. This return lever 20 comprises in the example described a rotary cage 22 and a return shaft 24 as well as a return return spring 26 intended to be housed inside the rotary cage 22. The rotary cage 22 comprises for example a means for retaining one end of a Bowden cable (not represented). This return assembly 20 is intended to be mounted on the support 12 as illustrated in FIG. 1.
In the example illustrated in Figure 2, the opening control 10 includes an electrical actuation portion 50 allowing electrical actuation of the ejection and / or retraction of the handle 16.
We will now describe in detail the electrical actuating part 50. For its electrical operation, as illustrated in Figure 2, the opening control 10 preferably further comprises a lever 30 for pivoting the handle 16 in ejection and / or in retraction.
As illustrated in Figure 2, the pivot lever 30 is preferably mounted to pivot about the pivot axis Al of the handle 16. Thus, in the example described, the pivot lever 30 is connected to the handle 16 by at least one common axis of rotation A1 fixed relative to the housing 12.
In addition, preferably, the underside 161 of the handle 16 includes a shoulder defining a substantially transverse support wall 42 (Figure 2) from which the internal branch 16.2 extends axially and against which comes to bear. the lever 30 to rotate the handle 16.
There is shown in detail an embodiment of a pivot lever 30 in Figure 3. This pivot lever 30 has for example a general shape of stirrup through which the internal portion 16.1 of the handle can be engaged (Figure 2). Thus, in the example described and illustrated in detail in FIG. 3, the stirrup 30 preferably comprises a body delimiting a frame inside which the internal branch 16.2 of the handle 16 can be introduced.
The stirrup 30 preferably comprises a stirrup head 34 extending over the handle 16. The stirrup 30 also preferably includes a stirrup floor 36 coming to bear from below the handle 16, in particularly against the bearing wall 42 of the handle 16. The head 34 and the floor 36 are preferably connected together by two bent side branches 31 at the top 33 of which the stirrup 30 is articulated. The bent side branches 31 have for example a general shape of "L" and the top 33 is formed at the angle of "L". The stirrup head 34 preferably comprises an upper transverse connecting bar 34 and the stirrup floor 36 is formed by a lower transverse connecting bar 36.
As can be seen in Figure 2, the transverse support wall is slightly inclined 42. In this example, the lower bar 36 of the stirrup 30 presses on this support wall 42. In addition, preferably , the upper bar 34 of the stirrup 30 extends above an upper face 16E of the handle 16, at the level of the internal branch 16.2. The upper face 16E of the handle 16 further comprises in this example a shape 40 in relief against which the upper bar 34 comes to extend. The presence of the lower bar 36 of the lever 30 makes it possible to create a leverage effect and, in particular, to facilitate the tilting of the handle 16 to its ejection position.
In the example described, this stirrup 30 can pivot about an axis Al to the handle 16 which is integral with the housing 12. For this purpose, in the example described, the stirrup 30 comprises a support d 'articulation 35, located at the point of the vertices 33, provided on each side with two bearings for guiding the rotation of the stirrup 30 around the axis Al.
In this example, the stirrup 30 has generally a generally front arch shape inside which the internal branch 16.2 is introduced in a direction of introduction substantially perpendicular or slightly oblique to the plane containing the arch. The arch preferably connects the head 34 and the floor 36 by two arcuate lateral arms 32. The ejection bracket 30 has for example first and second solid side cheeks 37 parallel parallel and perpendicular to the common axis of rotation A1.
The opening control 10 further comprises a return member 38 connected to the stirrup 30. This return member 38 is configured to return the stirrup 30 in a rest position corresponding to the flush configuration of the handle 16. This return member 38 preferably comprises a caliper spring provided with two external tabs and with a central part. It can be seen in FIG. 2 that each of the two legs of the caliper spring 38 is fixed to an interior wall of the housing 12.
In the example described, the handle 16 is also provided with a handle return member 28 which is placed between the stirrup 30 and the internal portion 16.2 of the handle 16 and which have the common axis the Al axis.
The handle return spring 28 has two tabs intended to be fixed to the stirrup 30 and a central part engaged with the internal portion 16.2, in particular in this example, engaged with the relief shape 40. The function of the handle return spring 28 is in this example, by a return force, to make up for a play between the internal portion 16.1 and the stirrup 30.
Preferably, the handle 16 is configured to pivot freely inside the lever 30 when the lever 30 is stationary against the handle return spring 28 16 within the limit of a predefined angular movement clearance inside the stirrup 30.
In addition, the electrical operating part 50 comprises in this example an electrical actuator 60 connected to an ejection arm 70 intended to extend transversely inside the housing 12 in a pivoting manner as can be seen in FIG.
1.
The electric actuator 60 is illustrated in detail in Figure 4. As illustrated in Figure 4, the actuator 60 preferably comprises a linear cylinder 62 provided with one end 64 cooperating with one end 72 of the arm to eject the ejection arm 70 about a vertical axis. For example, the end 64 includes a notch and the end 72 includes a protruding lug.
In the example described, the ejection arm 70, as illustrated in an example in FIG. 2, includes an end 74 pivotally mounted between two parallel flanges 76 of the housing 12.
In a second embodiment illustrated in Figures 7 and 8, the opening control 10 further comprises, optionally, a mechanical emergency part 100 allowing mechanical actuation of the movement of the handle 16 in case of Γ electrical actuation failure. In this second embodiment, the elements similar to the first embodiment bear identical references in the figures.
In this second embodiment, the opening control 10 further comprises a mechanism 100 allowing mechanical actuation of an ejection and retraction movement of the handle 16. According to this second embodiment of the invention, in the event that electrical operation proves impossible due to an electrical failure, the opening control 10 may comprise, in accordance with the invention, an emergency mechanism 100 preferably provided with an energy accumulator elastic. To recharge the elastic energy accumulator, the handle 16 must be pushed in towards the inside of the body. This action rotates the handle 16 about its axis A1 in opposition to its return spring 28. In mechanical operation, preferably, the lever 30 remains stationary. In fact, in manual mechanical operation, the lever 30 remains in its rest position because there is play between the lever 30 and the handle 16 allowing the movement of the handle 16 without biasing the lever 30.
In particular, in this second embodiment of the invention, the mechanism 100 is configured to be mechanically engaged in response to a driving action in the housing 12 of the handle 16, the end of the action d depression or relaxation being able to cause the triggering of the mechanism 100. The mechanism 100 thus comprises a kinematic chain for driving the handle 16 in movement in order to automatically drive the handle 16 in movement according to all or part of a stroke starting from the depressed position of the handle 16 in the flush position passing through the ejected position. Preferably, the mechanism 100 is configured to drive the handle 16 in movement over the entire stroke.
We will now describe the main aspects of the operation of an opening control according to the first embodiment of the invention with reference to Figures 5 and 6.
Initially, the handle 16 is in its flush position and the lever 30 is in a rest position (state A of Figures 5 and 6).
Then, the user gives for example an opening order to an on-board computer of the motor vehicle which sends an electronic signal to the actuator 60. This order causes a displacement of a jack 62 of the actuator 60 .
During the ejection phase of the handle 16, the actuator 60 transmits a movement via the cylinder 62 to the ejection arm 70. The ejection arm 70 is configured to drive the lever 30 to the against the return force of the spring 38 of the ejection lever, for example by pressing against the transverse bar 36 of the lever 30.
The lever 30, which is kept in the rest position by its return spring 38, is moved until the handle 16 reaches its ejection position. In this ejection position, the user can pull the handle 16, against the handle 28 spring 28, and act on the return lever 20 to actuate the lock cable. In addition, preferably, the spring 28 between the handle 16 and the lever 30 makes it possible to return the handle 16 to the ejected position at the end of the action of the user by accompanying the movement of the lever 30.
The electric actuator then causes the lever 30 to pivot until the handle 16 is positioned in accordance with state B of FIGS. 5 and 6.
Finally, during the retraction phase of the handle 16, the actuator 60 is for example supplied with an opposite polarity and moves the ejection arm 70 in the opposite direction. The ejection arm 70 then preferably accompanies the movement of the stirrup 30, the return spring 38 of which tends to return to its rest position. The handle 16 accompanies the lever 30 by the action of its return spring 28. The actuator 60 is in this example bistable. The handle 16 is again in its state A.
Of course, the invention is not limited to the embodiments described above. Other embodiments within the reach of the skilled person can also be envisaged without departing from the scope of the invention defined by the claims below.
