    [0001] The present invention relates to a device for closing an air inlet and an associated front-end module for a motor vehicle.
    [0002] The invention applies in particular to motor vehicles, in particular with an air-conditioning installation of the passenger compartment, such as, for example, a thermal treatment installation for a motor vehicle, that is to say installations having, in particular, the function of to heat, cool, filter and / or dehumidify the air injected into the passenger compartment, or air conditioning installations for comfort functions to, for example, purify, humidify or odorize the air of the passenger compartment of a vehicle. In general, a motor vehicle has on its front face a ventilation grille behind which are installed one or more heat exchangers of a thermal air conditioning installation of the passenger compartment. However, in cold weather, the air entering the engine compartment slows the rise in temperature of the engine and prolongs the initial polluting phase of it. In addition, this also slows down the warming of the passenger compartment, while the passengers on board the vehicle are in need of rapid heating in cold weather. To overcome this problem, it is known to equip the vehicle with a closure system disposed between the ventilation grille and the exchangers. Such a closure system is for example equipped with a multitude of pivoting flaps that can move between an open position, parallel to the incoming air flow and a closed position, perpendicular to the air flow. Thus, in cold weather, the shutters can be closed which allows the engine and the passenger compartment to be heated more quickly, and then to open these shutters according to the cooling needs of the engine and / or the passenger compartment. For some vehicle models, particularly off-road, the flaps are provided with seals to make the engine compartment 5 waterproof vis-à-vis the outside, especially for a fording. Although these known shutter systems have been proven, we try to avoid equipping a vehicle with such a system, especially because of the size of such a system in the longitudinal direction of the vehicle, 10 also called the x axis. US 2,783,978 describes schematically a bumper skin for a motor vehicle having an air inlet opening and a shutter of this opening. However, to develop forces necessary for the opening and closing of the shutter, especially when driving where large air forces impact the shutter, the shutter comprises lateral appendages with a remote pivot axis to form lever, having a large footprint. In addition, it has also been observed that the construction of a shutter 20 according to the diagrams described in one of the above documents makes it difficult to control an inadvertent opening of the shutter. The present invention aims to overcome at least partially some of the disadvantages described above. For this purpose, the subject of the invention is a device for closing off an air intake for a motor vehicle, intended to equip in particular a front-end module and comprising at least two shutters of the air intake which are pivotally movable between on the one hand a closing position in which the shutters prevent air from passing and on the other hand a retracted position in which air can pass through the air inlet, characterized in that at least one of the edges of one of the shutters, intended to be opposite the edge of the other shutter, has an elastic lip. The elastic lip ensures on the one hand a better seal and on the other hand a surface continuity between the two shutters. The device according to the invention may comprise one or more of the following characteristics taken alone or in combination: The elastic lip is made for example of elastomer, rubber or foam. The elastic lip can be fixed on the edge of the shutter by gluing, latching or overmolding.
    [0003] According to one aspect, the elastic lip has a frustoconical cross section whose base is visible from the outside. The elastic lip ensures in particular a surface continuity between the two shutters in the closed position. According to one variant, the peripheral periphery of each shutter is equipped with an elastic lip. The device may further comprise - a rotary control shaft offset from the axis of pivoting of the shutter and parallel to this pivot axis, - a drive actuator of the rotary control shaft, and 3037871 4 - to minus a crank-connecting mechanism connecting the rotary control shaft to the shutter so that rotation of the rotary control shaft moves the shutter to pivot. Since the shutters can be integrated into the outer skin 5 of the front-panel module, the space requirement is reduced along the longitudinal axis of a motor vehicle. In addition, the pivot axis can be arranged very close to the shutter. By using a rotary control shaft and a crank-crank mechanism, it can be very compact and has a great freedom of design to place the rotary control shaft in function of the vehicle on which the front panel module is to be mounted. Finally, the crank-crank mechanism ensures a good transmission of force to move the associated shutter. According to one aspect, at least one connecting rod-crank mechanism is for example centrally disposed relative to the shutter.
    [0004] The crank-handle mechanism is in particular oriented perpendicular to the axis of pivoting of the shutter and the rotary control shaft. In another aspect, the shutter has an outwardly curved shape and side trunnions defining the pivot axis of the shutter. It can further be provided that the connecting rod of the connecting rod-crank mechanism is connected to a bearing disposed at a distance from the axis of pivoting of the shutter. In yet another aspect, the crank-handle mechanism is configured to block the opening of the shutter in a closed position.
    [0005] In the closed position of the shutter, the crank of the connecting rod-crank mechanism is for example perpendicular to the shutter. A shutter typically has a width of between 0.6m and 1m and a height of between 10cm and 15cm.
    [0006] The shutter device may comprise two shutters for closing an air inlet opening and the shutters are driven through their respective rotary control axes in antagonistic pivoting directions. The invention furthermore relates to a front-end module for an automobile vehicle comprising an outer skin, for example a transverse skin, intended to be mounted perpendicularly to the longitudinal axis of the vehicle, to be visible from the outside of the vehicle and having an opening , eg transverse, air inlet, at least 15 shutter device as defined above having at least one shutter of the air inlet opening, which in the closed position provide continuity of surface with said outer skin. Other advantages and characteristics will appear on reading the description of the invention, as well as the appended drawings in which: FIG. 1 is a schematic perspective view of a front-end module equipped with shutters which are FIG. 2 is a schematic perspective view of a front-end module equipped with shutters which are in the open position; FIG. 3 is a schematic perspective view of the rear of two shutters with their respective driving mechanism; FIG. 4 is a schematic side view of a shutter 5 with its associated drive mechanism; FIG. 5 shows two shutters in the closed position, and FIG. VI of FIG. 5. In the present description, the term "upstream" means that one element is placed before another relative to the direction of flow of the air flow. On the other hand, "downstream" is understood to mean that one element is placed after another relative to the direction of flow of the air flow. By upper, lower, upper and lower, reference is made to the arrangement of the elements in the figures, which generally corresponds to the arrangement of the elements in the assembled state in a motor vehicle. The following achievements are examples. Although the description refers to one or more embodiments, this does not necessarily mean that each reference relates to the same embodiment, or that the features apply only to one embodiment. Simple features of different embodiments may also be combined to provide other embodiments. A LTH trihedron in a figure indicates respectively the longitudinal (L), transverse (T) and height (H) directions corresponding to x-y-z directions of the vehicle.
    [0007] In the description, it is possible to index certain elements or parameters, such as for example first element or second element as well as first parameter and second parameter, or first criterion and second criterion, and so on. In this case, it is a simple indexing to differentiate and name elements or parameters or criteria close but not identical. This indexing does not imply a priority of one element, parameter or criterion with respect to another, and it is easy to interchange such denominations without departing from the scope of the present description. This indexing does not imply either a time order. Figures 1 and 2 show a front panel module 1 for a motor vehicle to be mounted on the front of the vehicle. This front-end module 1 comprises an external transverse skin 3, made for example of plastic material by injection or molding, and intended to be mounted perpendicularly to the longitudinal axis L of the vehicle and parallel to the transverse axis T of the vehicle . This outer skin 3 with its front face 4 is visible from the outside of the vehicle and has both decoration / finish functions to emphasize the appearance of the vehicle that technical functions for example to cushion a shock in case of impact for example during an accident. This outer skin 3 has for example openings 5 to receive headlights, flashers or other lighting or signaling devices that are not shown in the figures. In addition, the outer skin 3 has at least one, in this case two openings or air inlets 7 and 9 including transverse orientation (best seen in Figure 2).
    [0008] The front-face module 1 comprises a shutter device comprising a first shutter 11 and a second and third shutter respectively referenced 13 and 15. As will be described in more detail, each shutter 11, 13 and 15 is movable. pivoting about a pivot axis 17 and may also be designated as a flap. For example, each shutter 11, 13 and 15 is oriented transversely and has a width of between 0.6m and 1m and a height of between 10cm and 15cm. It is thus clear that the front face module forms a closure frame for the closure device.
    [0009] According to a variant not shown, it is possible to provide a separate mounting frame of the front-end module which is fixed to an element of the front face such as the bodywork or to a supporting structure of the vehicle. The opening 7 can be closed by the shutter 11 while the opening 9, which is larger in the direction H, can be closed by the two shutters 13 and 15 which open or close while being driven by a pivoting movement according to antagonistic movements. The shutters 11, 13 and 15 are thus pivotally movable between on the one hand a closed position (FIG. 1) in which the shutters 11, 13 and 15 prevent air from passing and in which the shutters 11, 13 and 13 15 provide a surface continuity with said outer skin 3 and on the other hand a retracted position (Figure 2) in which the air can pass through the air inlet openings 7 and 9. Of course, the shutters 11, 13 and 15 may also take intermediate positions between the closed positions of Figure 1 and open of Figure 2.
    [0010] In particular to ensure surface continuity with the outer skin 3 of the module 1, each shutter 11, 13 and 15 has an outwardly curved shape, i.e. towards the front of the vehicle.
    [0011] FIG. 3 shows the shutters 13 and 15 on the downstream face 19, that is to say the face directed towards the engine compartment of the vehicle. At their transverse ends, each shutter 11, 13 and 15 carries lateral pins 21 defining the pivot axis 17 of the shutter.
    [0012] In addition, the shutter device comprises for each shutter a rotary control shaft 23 which is offset from the pivot axis 17 of the associated shutter and parallel to this pivot axis 17. According to the example shown in FIG. 3, each shutter 13 and 15 is associated with a drive actuator 25 which is disposed at an end 10 of the rotary control shaft 23 concerned. According to an example not shown, it is possible to provide a single drive actuator 25 with gears adapted to drive simultaneously two rotary control axes 23. However, it is preferable to have an actuator 25 for each of the 15 shutters 11, 13 and 15 to be able to move them pivotally independently of each other, which allows to regulate more finely the flow of air according to the climatic conditions on the one hand and the fresh air needs of the air conditioning installation d 'somewhere else.
    [0013] Each rotary control shaft 23 is connected by at least one crank-link mechanism 27 to the associated shutter 11, 13 or 15 so that a rotation of the rotary control shaft 23 via the actuator drive 25 moves the shutter 11, 13 or 15 pivotally.
    [0014] In order to optimize the power take-offs, at least one crank-and-crank mechanism 27 is centrally disposed with respect to the associated shutter 11, 13 or 15 and is oriented perpendicular to the pivot axis 17 of the obturator 11, 13 or 15 and the rotary control shaft 23. In more detail, the crank-connecting mechanism 27 has a connecting rod 29 5 connected to a bearing 31 disposed at a distance from the pivot axis 17 of the shutter concerned. 11, 13 or 15. To prevent accidental opening of the shutters 11, 13 or 15, for example by the force of the air acting on the shutter 11, 13 or 15 in the closed position, the connecting rod-crank mechanism 27 is configured so as to block the opening of the shutter 11, 13 or 15 in the closed position. As particularly visible in Figure 4, for this purpose, in the closed position of the shutter 11, 13 or 15, the crank 33 of the connecting rod-crank mechanism 27 is perpendicular to the shutter 11, 13 or 15. FIGS. and 6 show two shutters 13 and 15 in a perspective front view. To complete the sealing and the surface continuity in the closed position of the shutters 13 and 15 which are driven by means of their respective rotary control axes 23 in the direction of antagonistic pivoting, at least one of the edges one of the shutters 13 or 15, intended to be opposite the edge of the other shutter 15 or 13 has an elastic lip 50. This lip 50 is for example made of elastomer, rubber or foam and can be fixed on the edge 48 of the shutter 13 or 15 by gluing, latching or overmolding. The elastic lip 50 has a frustoconical cross section 25 whose enlarged base 52 is visible from the outside.
    [0015] Thus, the elastic lip provides surface continuity between the two shutters 13 and 15 in the closed position. Of course, the sealing lip 50 as well as the shutters 11, 13 and 15 and the outer skin 3 preferably have the same color and the same surface appearance.
    [0016] According to a variant not shown, the peripheral periphery of each shutter 11, 13 or 15 is equipped with an elastic lip 50. It is therefore understood that the shutters according to the invention make it possible to reduce the space requirement along the longitudinal axis of the vehicle. . In addition, in the closed position, the shutters 11, 13 or 15 provide surface continuity with the outer skin 3.
