    DEVICE FOR REGULATING AN AIR FLOW FOR AN AIR INTAKE FROM A FRONT MODULE BEFORE A MOTOR VEHICLE.
    _ The invention relates to a device for regulating (10) an air flow for an air inlet of a front panel module of a motor vehicle comprising a support frame (12) in which a plurality is installed shutter flaps (14) pivoting between a closed position and an open position. According to the invention, the regulation device (10) comprises a housing (20) intended to receive an electronic detection component (22).

    The invention relates to a device for regulating an air flow for an air inlet of a front panel module of a motor vehicle as well as a motor vehicle comprising such a regulating device.
    The front sides of motor vehicles are generally composed of a main air inlet or two air inlets, called upper track and lower track, separated by a bumper beam. Behind this bumper beam are generally placed the heat exchangers of the motor vehicle, such as that used for air conditioning the passenger compartment.
    A flap panel corresponding to a device for regulating the air flow is also generally mounted at the rear of the vehicle's air inlets.
    The flaps are formed of lamellae pivotally mounted transversely on a support frame. The inclination of the flaps can be controlled between a vertical closed position blocking the passage of air and several intermediate positions to a horizontal open position where maximum air flow can circulate.
    When the flap panel is in the closed position, the vehicle has a better coefficient of air penetration, which reduces fuel consumption and CO2 emissions. In addition, the piloted flaps are arranged in front of a heat exchange device, which makes it possible, in the closed position, to accelerate the rise in temperature of the exchangers in the heating phase by also reducing the consumption of the vehicle and therefore the emission of CO2.
    However, the space available under the hood between the bumper beam and the heat exchangers is relatively small, which can complicate the integration of the panel of piloted shutters with other components, such as the electric parking assistance radar. Indeed, as illustrated in FIG. 1 representing an air regulation device according to the prior art with a set of flaps 2 and a connecting rod allowing the simultaneous pivoting of the flaps 2 induced by the actuator 5, the electric radar 6 d parking aid is generally integrated or associated with the grille 8 of the vehicle in order to be as close as possible to the front of the vehicle. However, such an annoyance increases the size of the regulating device in a longitudinal direction X. In addition, the radar 6 disturbs the flow of the air flow F and thus creates turbulence, the flow of air not being laminar this reduces the cooling capacity of the heat exchangers, when the flaps are in the open position.
    Thus, one of the aims of the present invention is to propose a device for regulating the air flow making it possible to better optimize the space available under the hood of the vehicle. Another object of the present invention is to improve the efficiency of the air flow regulation device when the shutter flaps are in the open position.
    To this end, the subject of the invention is a device for regulating an air flow 15 for an air intake of a front panel module of a motor vehicle comprising a support frame in which a plurality is installed pivoting flaps around pivot axes between a closed position and an open position, characterized in that the regulation device comprises a housing intended to receive an electronic detection component.
    It is thus possible to obtain a device for regulating the air flow, the shape of which can follow that of the elements located in front of it, such as the bumper beam, the radiator grille or other reinforcing elements of the vehicle by being brought as close as possible vehicle air inlets, which increases the space available under the hood.
    The absence of obstacles as well as the increased distance between the air flow control device and the heat exchangers located downstream makes it possible to obtain a less turbulent, more laminar, faster and therefore more efficient air flow for cooling of heat exchangers.
    Also, the increase in the under-hood space gives space to arrange other vehicle components between the heat exchanger device and the air flow control device, such as a horn.
    According to one or more characteristics of the shutter panel, taken alone or in combination, suggests that:
    - The support frame comprises said housing intended to receive the electronic detection component;
    - The housing is defined by a housing comprising a hollow space in which is included the electronic detection component;
    - The housing comprises a cover so as to define with the housing a closed space in which is included the electronic detection component, said housing comprising an opening through which the connectors of the electronic detection component is able to pass through;
    - The support frame is adapted to be fixed to a grille;
    - The device further comprises a housing for a vision camera;
    - The housing includes fixing means for retaining the electronic detection component;
    - a connecting rod is arranged on either side of the electronic detection component;
    - the electronic detection component is arranged between two shutters;
    - an actuator is disposed between two shutters, near the electronic detection component, in the center of the air flow regulation device and configured to control the positioning of the shutters;
    - the electronic detection component corresponds to a vehicle positioning sensor;
    - the electronic detection component corresponds to a parking assistance radar, a vision camera, or any other sensor capable of detecting and providing one or more information on the environment of the vehicle;
    - the electronic detection component does not have a mobile element for actuating the shutters of the regulating device;
    - the electronic detection component makes it possible to deliver information on the vehicle environment to the vehicle's electronic control unit (ECU).
    The invention also relates to a motor vehicle comprising a grille and an air intake as well as a device for regulating an air flow as described above, the shutter flaps extending the continuity of the grille when 'they are in the open position.
    Other characteristics and advantages of the invention will appear on reading the description which follows. This is purely illustrative and should be read in conjunction with the accompanying drawings in which:
    îo FIG. 1 illustrates the front of a vehicle from a top view with a device for regulating the air intake and a parking assistance radar according to the prior art.
    Figure 2 illustrates the front of a regulating device according to the invention in association with a radiator grille in a perspective view.
    FIG. 3 illustrates the rear of a regulation device according to the invention in association with a grille in a perspective view.
    The regulating device 10 according to the present invention as illustrated in FIGS. 2 and 3 comprises a support frame 12 and a set of shutter flaps 14, here six in number, distributed in two sub-assemblies grouping three flaps d 'shutter 14 arranged on either side of the housing 20 for receiving the electronic detection component 22 which will be described later.
    The invention is not limited to the number of flaps present in the device. Indeed, it is conceivable to have a system with a first shutter 14 and a second shutter 14 covering between them the entire air intake surface. The device includes a set of identical shutters. This facilitates its construction.
    The regulating device 10 extends in a longitudinal (X), transverse (Y) and vertical (Z) direction, for example relative to the axes of the vehicle, as shown by the axes in FIG. 1.
    The support frame 12 corresponds to a frame with two longitudinal sides and two lateral sides for a given thickness. The support frame 12 has a rectangular shape, here in the shape of a trapezoid, so that the longitudinal sides are larger than the lateral sides. Obviously, the invention is not limited to the shape of the support frame 12, so one could envisage a support frame of oval, semi-elliptical shape or any other polygonal shape (in rhombus, pentagon, hexagon, etc.). The regulating device 10 is arranged so that all of the shutter flaps 14 as well as housing 20 intended to receive the electronic detection component 22, cover the entire interior surface of the support frame 12. The frame support 12 has a plurality of bearings into which pins or pins for pivoting shutter 14 are introduced.
    Each shutter 14 comprises an axis of rotation thus allowing, by rotation, to open and close said shutter. The rotational movement of the shutter flaps 14 is induced by an actuator 18. Opening a shutter flap 14 amounts to placing it (by rotation) in such a way that it opposes the passage of the flow as little as possible. air F by orienting it appropriately, here horizontally (in a plane defined by the directions XY). Closing a shutter 14 is equivalent to placing it so that it opposes the flow of air flow F as much as possible, in cooperation with the other shutters 14, by orienting it suitably, here vertically (in a plane defined by the directions YZ). The axes of rotation of the shutters 14 are parallel to each other. Thus, the rotations applied to all the shutter flaps 14 are all rotations along the same axis, except for one translation.
    When the shutter flaps 2 are in the open position as shown in FIGS. 2,3, that is to say that they extend in a longitudinal (X) and transverse (Y) direction, the air inlet is cleared and the outside air flow can pass through the passage of the support frame 12. When the shutters 14 are in the closed position, that is to say that they extend in a transverse direction ( Y) and vertical (Z), for example with respect to the axes of the vehicle, the air intake is closed and the air cannot pass through the support frame 12, in fact, in this position, the shutters 14 thus constitute an obstacle which opposes, by its front surface, to the circulation of the air flow F. Obviously, the shutter flaps 14 are capable of adopting any intermediate position.
    In other words, the regulating device 10 is configured to pass from a closed configuration where the shutter flaps 14 completely block the passage of the air flow F to an open configuration where the shutter flaps 14 are positioned. so as to let the air flow F pass with maximum flow.
    The regulating device 10 is subject to a grid or grille 16 of the motor vehicle. The grille 16 corresponds to an ornamental grid located at the front of the motor vehicle at the level of the air intake serving to embellish the exterior appearance of the vehicle while protecting the heat exchangers and other components of the engine compartment from exteriors (for example a tree branch, ...). The regulating device 10, in particular the support frame 12, is capable of being fixed to the grille 16. For this, the support frame 12 comprises fixing means 24, such as clips, for fixing to the grille 16. The regulating device 10, in particular the support frame 12, is also able to be fixed to the shield of the motor vehicle (not illustrated). For this, the support frame 12 comprises fixing means 26, such as tapped holes for a screw or threaded rod or clips, for fixing to the shield of the motor vehicle.
    The grille 16 corresponds to a grid with a grid, so as to allow the air flow to flow while preventing solid external bodies from coming inside the engine compartment. For this, the grille 16 comprises horizontal bars 28 extending over the width (transverse plane XY) of the air inlet and vertical bars 30 extending over the height (vertical plane XZ) of the inlet d 'air. The shutter flaps 14 are arranged so as to extend the continuity of the grille 16 when they are in the open position, in particular to extend the continuity of the horizontal bars 28 of the grille 16.
    Each shutter 14 includes a leading edge and a trailing edge relative to the air flow. The leading edge of the shutter 14 is the front section of the aerodynamic profile that constitutes the shutter 14. The trailing edge is the rear part of the profile of the shutter 14, the leading edge comes in contact with the grille 16 when the regulating device 10 is in the open position.
    The regulating device 10, and in particular the support frame 12, comprises a housing 20 intended to receive an electronic detection component 22. This housing 20 corresponds to a space arranged within the structure of the support frame 12 or more precisely to a box 32 forming continuity of material with the support frame 12, thus defining a hollow space in which can be understood, or inserted, the electronic detection component 22. According to the embodiment illustrated here, it is understood that the box 32 is assembled directly within the support frame 12, or in other words no intermediate plate is disposed between the support frame 12 and the electronic detection component 22.
    The support frame 12 and the electronic detection component 22 respectively comprise additional fixing means 34 which allow direct assembly without passing through an intermediate fixing plate, the shape of the parts in contact, in particular of the support frame 12 and of the electronic detection component 22, allowing such an assembly.
    The direct assembly of the electronic detection component 22 on the support frame 12 is carried out by means of at least one positioning means, namely the housing 32 which defines a hollow space in which the electronic detection component 22 can be correctly positioned and at least one fixing means 34 in order to hold the electronic detection component 22 within the housing 20, or box 32. The box 32 can also include a polarizing device (not illustrated) or poka-yoke in order to ensure that the electronic detection component 22 is correctly installed within the housing 32.
    The main function of the housing 32 is to correctly position the electronic detection component 22 within the support frame 12 so that the fixing means 34 can cooperate thereafter. It may be noted that the housing 32 can also have, once the means fixing 34 assembled, a holding and fixing function preventing the electronic detection component 22 from having certain degrees of freedom of movement.
    The fixing means 34 comprise, for example, a clip or hook assembly and a shoulder. Such an elastic fitting is such that the support frame 12 comprises a clip or a hook 36 which can be hooked to a surface of the electronic detection component 22, for example by means of a shoulder present on the electronic detection component 22 , in order to keep the latter in a fixed position, or vice versa.
    The fastening means 34 also include a threaded hole and threaded screw assembly, as illustrated in FIG. 3, the support frame 12 and the electronic detection component 22 have threaded holes so as to insert screws 38 therein in order to securely fix the electronic detection component 22 to the support frame 12.
    The fastening means 34 also include a clip or hook 36 which can be hooked onto the grille 16 in order to hold the grille 16 and regulating device 10 assembly securely.
    It is also possible to combine several fixing means 34 such as screws and clips so as to have a removable assembly, in particular for the replacement and / or repair of the electronic detection component 22. The fixing means 34 being designed to so as to be dismantled without significant deterioration of the electronic detection component 22 and / or of the support frame 12, so that they can, in particular the support frame 12, be reused to recreate another assembly.
    The housing 32 according to the embodiments illustrated in Figure 2 and 3 is an integral part of the structure of the support frame 12, so that it is not possible to dissociate them without having deterioration of the assembly.
    However according to an embodiment not illustrated, it is possible to design a housing as a separate, separate piece, and having fixing means to be secured to the regulating device 10, in particular to the support frame
    12.
    The housing 32 further comprises an opening 40 through which the connection of the electronic detection component 22 is able to pass through in order to be supplied with current as well as to be able to deliver information on the environment of the vehicle to the electronic control unit (ECU).
    The electronic detection component 22 corresponds to a vehicle positioning sensor. In particular, the electronic detection component 22 is chosen from a parking assistance radar, a vision camera, a proximity radar, a distance control radar or laser, or any other sensor capable of detecting and providing a or more information on the environment of the vehicle. The electronic detection component 22 makes it possible in particular to deliver this information to the electronic control unit (ECU) of the vehicle.
    The electronic detection component 22 does not have a movable element for actuating the shutters 14 of the regulating device 10.
    The housing 32 and the electronic detection component 22, once installed, are arranged in the center of the regulating device 10 so that a first shutter flap 14 and a second shutter flap 14 are arranged on either side other of the electronic detection component 22 and of the housing 32 as illustrated in FIGS. 2 and 3.
    The regulating device 10 further comprises a cover 42 which can be fixed either to the grille 16 or to the housing 32, so as to define with the housing 32 a closed space in which the electronic detection component 22 is included. Such a cover 42 protects the electronic detection component 22 from external elements (gravel, tree branches, etc.). The cover 42 is fixed to the grille 16 or to the housing 32 by means of fixing means 52 such as screws or clips. The cover 42 also comprises notches 50 of complementary shape to the calender 16 or to protuberances arranged on the housing 32.
    The regulation device 10 further comprises a housing 44 capable of accommodating a vision camera. It is thus possible to combine the information obtained by the two electronic components and thus have more reliable data as to the environment of the vehicle. It is also possible to arrange the vision camera directly on the grille 16.
    In order to guarantee the simultaneous rotation of the shutter flaps 14, the regulating device comprises a connecting rod 46 illustrated in FIG. 3 arranged on either side of the electronic detection component 22 and of the housing 32. This connecting rod 46 is movable according to a movement in translation in the vertical direction (Z), makes it possible to secure the various shutter flaps 14 in a simple and inexpensive manner by using few parts. Indeed, the actuator 18 inducing the rotation of one of the shutter flaps 14, causes the translation of the connecting rod 46 which in turn causes the rotation of the other shutter flaps 14 linked to the connecting rod 46.
    As illustrated in Figure 3, the rod 46 corresponds to a rectangular frame with a cavity in its center so that the housing 32 can be arranged inside this cavity so that the rod 46 is able to be move in translation without being hindered in its movement by the housing 32.
    The invention also relates to a vehicle comprising the grille 16 and an air intake. The vehicle includes a regulating device 10 as described above, the shutter flaps 14 extending the continuity of the grille 16 when they are in the open position.
    It should be understood, however, that these exemplary embodiments are given by way of illustration of the subject of the invention. The invention is not limited to these embodiments described above and provided only by way of example. It encompasses various modifications, alternative forms and other variants that a person skilled in the art may envisage in the context of the present invention and in particular any combination of the various embodiments described above.
