    The present invention relates to shutter devices and more specifically a device for shutting the air inlet of the front lace of a motor vehicle as well as its labrication process.
    The front laces of motor vehicles are generally composed of two main air inlets, called upper track and lower track, separated by a bumper beam. Behind this bumper beam, heat exchangers for the motor vehicle are generally placed, such as that used for air conditioning the passenger compartment and / or that used for cooling the engine.
    It is also known to have, in the air path passing through the main air inlets, and more generally the low track, a support frame comprising a multiplicity of flaps mounted pivoting around parallel axes and suitable for taking a multiplicity different angular positions, between an open position and a closed position, under the action of appropriate control means, thus forming a shutter device akin to jealousy. This shutter device is sometimes called an active grille shutter, or a piloted air intake module. Such a shutter device can also be designated by the acronym AGS (for "Active Grille Shutter" in English).
    The shutter allows you to adjust the air flow through the air inlets and arriving at the heat exchangers. It is thus possible to optimize the efficiency of these heat exchangers as needed by varying the amount of air they receive. In addition, at high speed, the shutters in the closed position reduce the drag coefficient of the motor vehicle and thus improve the aerodynamics of said motor vehicle. The shutter device therefore reduces energy consumption and pollution when the engine does not need to be cooled by outside air.
    The shutter device conventionally comprises an actuator (also called an actuator or motor) controlling the flaps and allowing the opening or closing of the air intake: the flaps are opened when the engine of the motor vehicle needs 'be cooled and the flaps are closed when the motor vehicle engine is sufficiently cooled.
    There are known from the prior art housings arranged on the support frame intended to accommodate the actuator. However, the actuator is installed and maintained inside this housing using fixing screws. Such fixing screws are additional components of the closure device. Furthermore, the use of these fixing screws requires a specific assembly step during the manufacturing process of the shutter device, this specific step therefore increases the manufacturing time of this shutter device and therefore has a cost. On the other hand, during the manufacturing process of this obturation device, it is possible to encounter problems linked to the screwing stroke, or even to the screwing of these fixing screws, which can lead to manufacturing defects of the device. shutter, requiring the disposal of this shutter device. In addition, such fixing screws can become detached from the support frame because of vibrations, for example that the shutter device may be subjected to during the operation of the motor vehicle. This separation can affect the proper functioning of the shutter device and can damage the actuator.
    One of the objectives of the present invention is therefore to at least partially remedy the drawbacks of the prior art set out above.
    Another objective of the present invention, different from the previous objective is to provide a closure device allowing the installation of the actuator without requiring the use of fixing screws.

    In these figures, identical elements have the same numerical references.
    The following embodiments 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 characteristics apply only to a single embodiment. Simple features of different embodiments can also be combined or interchanged to provide other embodiments.
    In the following description, reference is made to first and second surfaces of the fixing holes and to first and second ends of the positioning elements. It is a simple indexing to differentiate and name similar but not identical elements. This indexing does not imply a priority of one element over another and one can easily interchange such names without departing from the scope of this description. This indexing also does not imply an order in time for example to assess the structure of the shutter device, or even the arrangement or cooperation of the various elements constituting it.
    In the following description, reference is made to an orientation as a function of the Longitudinal, Vertical axes and defining a Height as defined arbitrarily by the trihedron H, L, V, in particular represented in FIGS. 1, 2 and 3B to 6D. The choice of names for these axes is not limiting of the orientation that the shutter device can take in its application to a motor vehicle.
    Furthermore, the term “front face of the support frame” is understood to mean, in the following description, the part of the support frame disposed first in the air flow passing through the shutter device in normal operation of the motor vehicle. Likewise, the term "rear face of the support frame" means the part of the support frame opposite the front face of the support frame.
    Referring to Figures 1 and 2, there is shown a shutter device 1 for the air inlet of the front face of a motor vehicle according to a first embodiment (Figure 1) and according to a second embodiment (Figure 2) .
    The shutter device 1 comprises a support frame 3. The support frame 3 has two lateral uprights 31 interconnected by two end cross members 33 defining an opening. Furthermore, the support frame 3 has a front face and a rear face. In addition, at least one set of flaps 35 is installed in the support frame 3, and more particularly in the opening defined by the lateral uprights 31 and the end crosspieces 33. The flaps making up the at least one set of flaps 35 are pivotally installed between a shutter position in which they oppose the passage of the air flow through the shutter device 1 and an open position in which they allow the passage of the air flow through the device shutter 1. Furthermore, the support frame 3 can optionally have one or more reinforcing elements 36 of the flaps arranged between the lateral uprights 31 and parallel to these lateral uprights 31. These reinforcing elements 36 are arranged between two sets flaps 35. These reinforcing elements 36 make it possible to prevent the flaps from bending, for example under the effect of the pressure of the air flow exerted on them, for example. mple. Furthermore, the reinforcing elements 36 can serve as support for the flaps for their rotation. The shutter devices 1 shown with reference to FIGS. 1 and 2 each have a single reinforcing element 36, but a greater number of reinforcing elements 36 can be provided.
    On the other hand, the shutter device 1 comprises at least one control element configured to control the positioning of the flaps. The at least one control element comprises at least one control member (not shown), for example a connecting rod, connected to the flaps, an actuator 5 (visible in FIGS. 3A and 3B), and a lever (not shown) connected on the one hand to the actuator 5 and on the other hand to the control member so as to allow the pivoting of the flaps of the set of flaps 35.
    The shutter device 1 also includes a housing 7 disposed on the support frame 3. The housing 7 is configured to receive the actuator 5 and the control member. Furthermore, the housing 7 has an opening covered by a cover 9 (in particular visible in FIGS. 5A, 6A and 7A). According to the particular embodiments of FIGS. 1 and 2, the housing 7 comes integrally with the support frame 3. More particularly, the housing 7 is molded with the support frame 3 in order to limit the presence of joints which may possibly form zones of fragility.
    On the other hand, the cover 9 is fixed to the housing 7 by any means known to those skilled in the art. According to the particular embodiments shown with reference to Figures 1 and 2, the cooperation between the cover 9 and the housing 7 is by snap-fastening. Advantageously, the snap-fastening of the cover 9 to the housing 7 makes it possible to prevent the separation of these elements due to vibrations during the operation of the motor vehicle.
    According to the first embodiment shown with reference to Figure 1, the shutter device 1 has three sets of flaps 35, two of which are arranged on either side of the control element and therefore of the housing 7. According to this first embodiment, the opening of the housing 7 is arranged on the front face of the support frame 3 and the housing 7 extends perpendicular to the longitudinal axis of the end cross members 33, that is to say along the 'V axis of the trihedron. More precisely, the housing 7 is installed on an upright 40 disposed between the two lateral uprights 31. Thus, the control element can drive the three sets of flaps 35 of the shutter device 1. Advantageously, the arrangement on the front face of the housing 7 makes it possible to use a weaker hood fixing system 9, for example by snap-fastening, since it is pushed onto the support frame 3 by the air flow during the operation of the motor vehicle.
    According to a variant not shown here of this first embodiment, the opening of the housing 7 can be arranged on a lateral upright 31 of the support frame 3 and the housing 7 extends perpendicular to the longitudinal axis of the end crosspieces 33 , that is to say along the axis V of the trihedron. According to this variant, the shutter device 1 has a single set of pivoting flaps 35.
    According to another variant not shown, the opening of the housing 7 can be arranged on the rear face of the support frame 3 and the housing 7 extends perpendicular to the axis of the end crosspieces 33, that is to say along the V axis of the trihedron. According to this other variant, the housing 7 can be arranged both at the intermediate upright 40 as at a lateral upright 31 of the support frame 3. Thus, the shutter device 1 according to this other variant can have one or two sets of pivoting flaps 35 depending on where the housing 7 is installed.
    According to the second embodiment shown with reference to Figure 2, the opening of the housing 7 is disposed on a lateral upright 31 and the housing 7 extends in the extension of the end crosspieces 33, that is to say say parallel to the L axis of the trihedron. According to this second embodiment, the control element controls a single set of flaps 5.
    With reference to FIGS. 3A and 3B, there is shown the actuator 5 intended to be installed in the housing 7 in order to control the set of flaps 35. The actuator 5 has fixing orifices 51, and more particularly according to this mode three fixing holes 51. The presence of three fixing holes 51 makes it possible to position the actuator in the housing 7 and also to keep it fixed in the different directions of the space when the cover 9 covers the opening of the housing 7. However, the actuator 5 may have a different number of fixing orifices 51, such as for example two, four or more. The fixing orifices 51 have a first surface 53 intended to be positioned opposite the housing 7 when the actuator 5 is installed on the support frame 3 and a second surface 55 opposite the first surface 53. Furthermore, the actuator 5 has an external face 57 intended to be disposed opposite the cover 9 when this cover covers the opening of the housing 7. On the other hand, the actuator 5 also has a connection plug 59 intended to be connected to a control unit (not shown) for electrically supplying the actuator 5 or even for controlling the positioning of the flaps during the operation of the motor vehicle according to the need to cool the engine for example.
    With reference to FIGS. 4A to 7C, there is shown in greater detail the housing 7 (in particular in FIGS. 4A, 4B, 6B and 7B) and the cover 9 (in particular in FIGS. 5B, 6C and 7C), as well as the cooperation of the 'actuator 5 with the housing 7 (Figures 4B, 6B, and 7B) according to different particular embodiments.
    The housing 7 has positioning elements 73, intended to be inserted in the fixing holes 51 of the actuator. 5 Thus, these positioning elements 73 make it possible to center the actuator 5 inside the housing 7 and to block the movements of this actuator 5 along the axes V and H of the trihedron. Each positioning element 73 has a first end 73a connected to the housing 7 and a second free end 73b configured to cooperate with the fixing orifice 51. More particularly according to these embodiments, the positioning elements 73 correspond to fingers having a stop 75, in particular illustrated in FIG. 4A, configured to serve as a support for the first surface 53 of the fixing orifice 51. The first surface 53 of the fixing orifice 51 is arranged opposite the first end 73a of the positioning element 73 as illustrated with reference to FIGS. 4B, 6B and 7B. According to these particular embodiments, the fingers are flared in the direction of the first end 73a of the positioning element 73. Advantageously, the presence of these positioning elements 73 makes it possible to dispense with the use of fixing screws in order to allow the installation of the actuator 5 in the housing 7 when the opening of the housing 7 is covered by the cover 9. In addition, the positioning elements 73 can absorb the torque of the actuator 5 when the latter pivots the flaps of the set of flaps 35.
    The cover 9 (visible in FIGS. 5B, 6C and 7C) has at least one specific shape 93, 97 configured to keep the actuator 5 fixed relative to the first end 73a of the positioning elements 73 when the cover 9 is fixed. on the housing 7, and more particularly when the cover 9 is snapped in according to the different embodiments shown here. Thus, when the cover 9 is snapped onto the housing, the actuator 5 is held against the stops 75, and more precisely the first surface 53 of the fixing orifices 51, and its movements in the different directions of space can be warned, which keeps the actuator 5 fixed without requiring the use of fixing screws.
    With reference to FIGS. 4A to 5B, a first variant of the shutter device 1 is shown. According to this first variant, the latching of the cover 9 on the opening of the housing 7 takes place in a direction parallel to the positioning elements 73 , and more particularly along the axis L of the trihedron. Furthermore, the actuator 5 is disposed on a lateral upright 31 of the support frame 3 and pivots a single set of flaps 35, the shutter device 1 therefore corresponds to the shutter device 1 shown with reference to FIG. 2 .
    Referring to Figure 4A, the housing 7 has four positioning elements 73 of the actuator. Thus, the actuator 5 comprises, according to this particular embodiment, four fixing holes 51 intended to cooperate with these four positioning elements 73 as shown with reference to FIG. 4B. The presence of the four positioning elements 73 makes it possible to center the actuator 5 and to prevent its possible displacements in the different directions of space. Furthermore, the torque of the actuator 5 can be distributed over the various positioning elements 73, which makes it possible to prevent possible fatigue of the positioning elements 73 which can create weaknesses, or even a rupture of these positioning elements 73.
    Referring to Figures 4A to 5B, the housing 7 has openings 77 intended to cooperate with complementary shapes 100 carried by the cover 9 in order to allow the cooperation of the cover 9 with the housing 7 by snap-fastening, and therefore the fixing of the cover 9 on the opening of the housing 7. The openings 77 are arranged on fixing lugs 79 extending in the extension of the opening housing the actuator 5. The cover 9 has meanwhile the complementary shapes 100 (visible on the Figure 5B) arranged at its periphery. More specifically, the housing 7 has four fixing lugs 79 extending parallel to the longitudinal axis of the end cross members 33, that is to say parallel to the axis L of the trihedron. On the other hand, the fixing lugs 79 are arranged along the height of the support frame 3, that is to say along the axis H of the trihedron. The complementary shapes 100 are arranged on the side walls 101 of the cover 9.
    With reference to FIG. 5B, the at least one specific shape corresponds to a blind orifice 93 configured to receive the second end 73b of a positioning element 73. According to the particular embodiment shown here, the cover 9 has four orifices blind 93 intended to cooperate with the four positioning elements 73.
    According to other embodiments not shown here, the cover 9 may have a different number of blind holes 93. More generally, the cover 9 has as many blind holes 93 as the housing 7 has elements positioning 73. In fact, the cooperation of the blind holes 93 with the positioning elements 73 makes it possible to center the cover 9 on the opening of the housing 7 and also to keep the actuator 5 fixed in the housing 7.
    Furthermore according to the particular embodiment of Figure 5B, the blind holes 93 may have a cylindrical shape or elliptical section intended to accommodate at least the second end 73b of the positioning elements 73. According to this first variant, each blind hole 93 has a free end 93a cooperating with the second surface 55 of the fixing orifice 51 so that the first surface 53 of the fixing orifice 51 comes into contact with the stop 75 during the snap-fastening of the cover 9 on the opening, thus making it possible to keep the actuator 5 fixed inside the housing 7. Optionally, the free end 93a of the blind holes 93 may have a wedge made of elastomeric material, for example configured to absorb shocks and the vibrations that the shutter device 1 may be subjected to during the operation of the motor vehicle in order to imitate the fatigue of positioning elements 73.
    Optionally, as shown with reference to FIG. 5B, the cover 9 may have a shrinkage of material 95 configured to receive a foam intended to come to bear on the external face 57 of the actuator 5 in the mounted state of the cover 9 on the opening of the housing 7. The presence of this foam disposed in the cover 9 makes it possible to strengthen the holding in position of the actuator 5 inside the housing 7 because this foam pushes the actuator 5 against the stops 75 carried by the positioning elements 73. According to an embodiment not shown here, the holding in place of the actuator 5 inside the housing 7 can be ensured directly by the foam. Thus, the presence of blind holes 93 may not be necessary.
    As a variant or in addition according to an alternative not shown here, the at least one specific shape may correspond to a rib coming to bear on the external face 57 of the actuator 5 in the assembled state of the cover 9 on the opening of the housing 7 so as to press the actuator 5 into the housing 7 when the cover 9 is snapped into place with the housing 7.
    On the other hand, with reference to FIG. 5A, the housing 7 and the cover 9 in the assembled state have a notch (not shown) in order to allow the passage of a connection cable (not shown) making it possible to connect the connection plug 59 of the actuator 5 to the control unit.
    According to another embodiment not shown here, this first variant can be used on the closure device 1 of FIG. 1, that is to say when the housing 7 extends perpendicular to the longitudinal axis of the sleepers end 33, therefore along the axis V of the trihedron. According to this other embodiment, the housing 7 can be disposed both at the level of a lateral upright 31 as well as of an upright 40 disposed between the two lateral uprights 31. Furthermore, the housing 7 can be disposed on the front face or on the rear face of the support frame 3.
    Referring to Figures 6A to 7C, there is shown a second (Figures 6A to 6C) and a third (Figures 7A to 7C) variants of the closure device 1. According to these second and third variants, the opening of the housing 7 is disposed in the extension of the end crosspieces 33 and extends along the axes L and V of the trihedron. According to these second and third variants, the cover 9 has an extension 10 extending parallel to the longitudinal axis of the end crosspieces 33 in the fixed state of the cover 9 on the housing 7. The extension 10 is intended to come in contact with bearings allowing the fixing of the at least one set of flaps 35.
    According to these second and third variants, the actuator 5 is arranged on a lateral upright 31 of the support frame 3. On the other hand, the latching of the cover 9 on the opening of the housing 7 takes place in a direction perpendicular to the elements of positioning 73, and preferably perpendicular to the plane defined by the support frame 3, that is to say along the axis V of the trihedron.
    With reference to FIGS. 6A and 7A, the connection plug 59 of the actuator 5 projects from the housing 7 and from the cover 9 in the assembled state of these two elements in order to allow the connection of the actuator 5 to the unit. control.
    With reference to FIGS. 6B and 7B, the housing 7 has three positioning elements 73 each having a stop 75. Furthermore, the actuator 5 has three fixing orifices 51 cooperating with the positioning elements 73.
    The housing 7 also has openings 77 configured to cooperate with the complementary shapes 100 carried by the extension 10 of the cover 9 (visible in FIGS. 6C and 7C) in order to ensure the fixing of the cover 9 to the housing 7 by snap-fastening. Furthermore, the housing 7 optionally has positioning openings 80 of the cover 9. The positioning openings 80 are intended to cooperate with positioning pins 103 disposed on the cover 9 in order to guide the cover 9 so as to facilitate its click into place with housing 7 and strengthen its cooperation with housing 7.
    With reference to FIGS. 6C and 7C, the at least one specific shape corresponds to a rib 97 coming against the external face 57 of the actuator 5 disposed opposite the cover 9 in the assembled state of the cover 9 on the opening of the housing 7 so as to press the actuator 5 into the housing 7 when the cover snaps in. According to the particular embodiments shown here, the cover 9 has two ribs 97 intended to cooperate with the actuator 5 in order to press the latter in the housing 7. According to these particular embodiments, the ribs 97 are arranged on the cover 9 so as to come to press on an upper part of the actuator 5 for one of the ribs 97 and on a lower part of the actuator 5 for the other rib 97. According to an alternative not shown here, the cover 9 may have a single rib 97 arranged on the cover 9 so as to come to press in the middle of the actuator 5 during enc liquefying the cover 9 on the opening of the housing 7.
    According to the second variant shown with reference to Figures 6A to 6C, the housing 7 has two openings 77 on each end crosspiece 33 intended to cooperate with the complementary shapes 100 carried by the extension 10 of the cover 9. According to the embodiment particular of Figure 6C, the complementary shapes 100 are arranged on arms 102. Advantageously, the arrangement at the front face of the support frame 3 of the cover 9 allows easy access to this cover 9 and can allow rapid disassembly of this cover 9 allowing for example a rapid replacement of the actuator 5 if necessary. Furthermore, the air flow in operation of the motor vehicle can press the cover 9 against the support frame 3 and more particularly on the housing 7, thus preventing any separation of the cover 9 and the housing 7.
    According to this second variant, and with reference to FIG. 6C, the ribs 97 are planar. Thus, the actuator 5 is pressed against the stops 75 carried by the positioning elements 73 before the cover 9 is snapped into place with the housing 7.
    With reference to FIG. 6C, the extension 10 of the cover 9 optionally has semi-spherical cheeks 99, also called clamps, intended to cover an extremal part of the flaps in order to form a protective barrier making it possible to limit the quantities dust and debris which may arrive at this extreme part of the flaps. Advantageously, the presence of these cheeks 99 makes it possible to prevent certain malfunctions of the shutter device 1 by preventing the deposition of dust at the ends of the flaps allowing the latter to pivot.
    According to the third variant shown with reference to FIGS. 7A to 7C, the ribs 97 (visible in FIG. 7C) are chamfered so as to press the actuator 5 to press it into the housing 7 at the end of the travel of the cover 9 during the snap-fitting of the cover 9 and its extension 10 onto the opening of the housing 7. Advantageously, such a shape of the ribs 97 makes it possible to limit the forces exerted on the positioning elements 73 during the positioning of the cover 9 on the opening of the housing 7. In fact, the cover 9, and more precisely the at least one rib 97 corresponding to the specific shape, in such a configuration is in contact with the actuator 5 only when it is snapped into the housing 7.
    Furthermore, according to this third variant, the actuator 5 is arranged at the rear face of the support frame 3. In order to reinforce the cooperation of the cover 9 with the housing 7, the complementary shapes 100 carried by the cover 9 can be produced in a hyper-rigid material. Thus the latching of the cover 9 with the housing 7 is done by playing on the flexibility of the support frame 3, which improves the wind resistance of the assembly composed of the cover 9 and the housing 7. Advantageously, this improvement wind resistance makes it possible to position the housing 7, and therefore the actuator 5, on the rear face of the support frame 3.
    According to an alternative, not shown, of this third variant, the housing 7 can be arranged at the level of the front face of the support frame 3.
    The present invention also relates to a method of manufacturing the shutter device 1 described with reference to Figures 1 to 7C. The support frame 3 is generally obtained by injection molding. As stated above, the housing 7 is molded with the support frame 3 in order to limit the zones of weakness formed by the joints.
    The method comprises a step of installing the actuator 5 provided with the lever in the housing 7. This installation step is done by cooperation of the fixing orifices 51 of the actuator 5 with the positioning elements 73. The lever is then connected to the control member in order to form the control element allowing the flaps to pivot between their open position and their closed position.
    The method then comprises a step of installing the flaps making up at least one set of flaps 35 inside the support frame 3.
    The method then implements a step of connecting these flaps to the control member in order to allow them to pivot between their closed position and their open position under the effect of the actuator 5.
    The method then comprises a step of blocking the actuator 5 inside the housing 7 by fixing the cover 9 by snap-fastening on the opening of the housing 7.
    The exemplary embodiments developed above are examples provided by way of illustration and without limitation. Indeed, it is entirely possible for those skilled in the art to modify the number of fixing orifices 51 of the actuator 5 as well as the number of positioning elements 73 disposed in the housing 7 without leaving the part of the present invention. Then, a person skilled in the art can use any other method of manufacturing the support frame 3 than an injection molding process, such as for example 3D printing, without going beyond the scope of the present invention.
    Thus, obtaining a shutter device 1 whose cost and manufacturing time are improved is possible thanks to the shutter device 1 in which the actuator 5 is kept fixed inside the housing 7 thanks to the positioning elements 73 and snap-fitting of the cover 9, thus making it possible to dispense with the use of fixing screws 5 to keep the actuator 5 fixed inside the housing 7 as described above.
