    AIR INTAKE MANAGEMENT SYSTEM FOR FRONT PANEL OF
    The invention relates to an air management system of an air intake for a motor vehicle front end.
    Such a system generally comprises at least one flap and a device for controlling the displacement of the at least one flap between a closed position of the air inlet and at least one open position of the air inlet.
    Such a system is most often referred to by the acronym AGS, derived from the English phrase "Active Grid Shutter".
    The air intake management system is preferably installed at a radiator grille of the motor vehicle.
    In the open position of the air inlet, the air can circulate through the calender and participate in particular in cooling the engine of the motor vehicle.
    In the closed position of the air inlet, the air does not enter via the grille which reduces drag and thus reduces fuel consumption and carbon dioxide emissions.
    The air intake management system therefore reduces energy consumption and pollution when the engine does not need to be cooled by outside air. Generally, each flap is provided with a pivot pin of said at least one flap, the system comprising a support provided with at least one bearing configured to receive the pivot pin and a closure element of the bearing.
    The pivoting of the pin in the bearing allows the passage from the open position to the closed position, and vice versa from the closed position to the open position. On the other hand, each flap is generally equipped with an actuating finger secured to movement of a rod controlled by the control device.
    Thus, a displacement of the connecting rod causes a pivoting of the actuating finger, which leads to the pivoting of each flap.
    However, while the displacement of the connecting rod must be in a preferred direction, for example perpendicular to the pivot axis of the flaps, it is not uncommon for the rod to undergo lateral movements, or louvoisements, which disturbs opening and closing the system.
    The object of the invention is to overcome this disadvantage. For this purpose, the subject of the invention is an air management system of an air inlet for a motor vehicle front surface, comprising at least one flap and a frame for maintaining said at least one flap, said at least one flap a flap being provided with a pivot pin of said at least one flap, the system comprising a support provided with at least one bearing configured to receive said pivot pin of said at least one flap and a closure element of said at least one bearing , the system comprising a device for controlling movement of said at least one flap between a closed position of the air inlet and at least one opening position of the air inlet by pivoting the pivoting peg at level of the bearing, said at least one flap comprising an actuating finger of said at least one flap, integral in motion with a rod controlled by the control device, the management system being characterized in that the closure member ure guiding shape of the connecting rod.
    Thus, thanks to the system according to the present invention, the connecting rod is not free in motion but on the contrary guided, which avoids any deviation of trajectory, and, in particular, any parasitic movement of swaying.
    According to another characteristic of the invention, the closure element comprises a slideway for guiding the connecting rod.
    According to another characteristic of the invention, the slideway comprises two rails, each of the rails having a general shape complementary to a movement of the connecting rod.
    According to another characteristic of the invention, each rail has a generally wavy shape.
    According to another characteristic of the invention, the closure element comprises a closure wall of said at least one bearing.
    According to another characteristic of the invention, the closure element comprises a support wall on the frame.
    According to another characteristic of the invention, the system comprises a means for retaining the closure element to the holding frame.
    According to another characteristic of the invention, an end of the closure element is shaped to form the retaining means.
    According to another characteristic of the invention, the end of the closure member comprises a tab configured to cooperate with one end of the slide so as to grip a portion of the frame and / or a part of the support of said at least one bearing and / or a lug for holding the tab against the frame.
    According to another characteristic of the invention, the system comprises a plurality of shutters.
    According to another characteristic of the invention, the system is devoid of screws between the closure element and the frame. 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: - Figure 1 illustrates a perspective view of an air intake management system according to the present invention in a first position; FIG. 2 illustrates a perspective view of an air intake management system according to the present invention in a second position; - Figure 3 illustrates a cross sectional view of the system of Figure 1; FIG. 4 illustrates a detailed perspective view of the system of FIG. 1; and FIG. 5 illustrates a perspective view of the system of FIG. 1 during assembly.
    The invention relates to an air management system of an air inlet for a motor vehicle front face.
    The system is most often referred to by the acronym AGS, derived from the English phrase "Active Grid Shutter".
    The air intake management system is preferably installed at a radiator grille of the motor vehicle, and allows an air flow control passing through the front face of the vehicle, including a motor compartment of the vehicle.
    In the figures, the management system is referenced 1, while the air inlet managed by the management system 1 is referenced 2.
    As can be seen in FIGS. 1 and 2, the management system 1 of an air inlet 2 comprises at least one flap 3.
    In the illustrated embodiment, the management system 1 comprises a plurality of shutters 3.
    As can be seen in FIGS. 1 and 2, the management system 1 also comprises a frame 4 for holding, preferably rigid, the plurality of shutters 3.
    The frame 4 has a generally rectangular shape.
    The frame 4 defines the air inlet 2 flaps 3 open and close, as will be detailed later.
    The frame 4 comprises two opposite upper and lower crosspieces, 4a, and two opposite uprights 4b.
    In the installation position in the motor vehicle, the frame 4 is configured so that the cross members 4a extend substantially horizontally, while the uprights 4b extend substantially vertically.
    In Figures 1 and 2, the flaps 3 are arranged parallel to one below the other.
    Of course, the invention is not limited to the illustrated embodiment, and, in particular, the number of flaps and the position of the flaps relative to each other may vary.
    Each shutter 3 includes a work surface 5.
    For example, the work surface 5 is a generally rectangular flat panel.
    Of course, the invention is not limited to planar rectangular flaps, and other configurations are quite conceivable.
    Each flap 3 comprises an axis 6 secured to the working surface 5.
    In Figures 1 and 2, the axes 6 extend substantially horizontally.
    Each flap 3 is pivotally mounted between a closed position of the air inlet 2 and at least one open position of the air inlet 2.
    In the closed position of one of the flaps 3, also called the closed position, the working surface 5 covers part of the air inlet 2.
    In each open position, the working surface 5 forms a non-zero angle with a virtual plane surface of the air inlet 2, which allows a flow of air to pass through the air inlet 2.
    As can be seen in FIGS. 1 and 2, the management system 1 also comprises a control device 7 for moving the shutter (s) 3.
    The control device 7 is advantageously an actuator.
    According to the variant embodiment illustrated, a single actuator 7 controls all the shutters 3.
    Advantageously, the management system comprises a kinematics such that all the flaps 3 of the management system 1 have an identical displacement, as will be detailed later.
    However, the invention is not limited to this case and it is conceivable to provide flaps whose movements are not identical.
    As shown in Figure 1, in the open position of the flaps 3, the air inlet 2 is traversed by a stream of air.
    This position is particularly advantageous when the vehicle engine requires significant cooling.
    In FIG. 2, the air inlet 2 is completely closed by the working surfaces 5.
    This position is particularly advantageous when the vehicle is traveling at high speed since the closing of the air intake 2 improves the aerodynamics of the motor vehicle and thus allows a reduction in fuel consumption.
    In this, the flaps 3 can be qualified as motor vehicle drag coefficient reduction flaps.
    As can be seen in FIGS. 1 and 2, each flap 3 comprises a pivoting pin 10 extending preferably from a disk 11 secured to one end of the working surface 5, in the extension of the axis 6.
    As also visible in the figures, the system 1 comprises a support 12 provided with bearing cutouts 13, each bearing 13 being configured to receive a pivot pin 10 of one of the shutters 3.
    The pivoting of each pin 10 in the associated bearing 13 allows the pivoting of the working surface 5 between the closed position and the opening position or positions.
    The system 1 comprises a closure element 14 of the bearings 11.
    As particularly visible in FIGS. 1 to 3, each flap 3 comprises an actuating finger 15.
    The finger 15 extends parallel to the pin 10 and facing the pin 10 from the disk 11.
    The system 1 also comprises a rod 16 controlled by the actuator 7 via a lever 17.
    The connecting rod 16 is preferably made of elastomer.
    The rod 16 extends in a longitudinal direction parallel to the uprights 4b.
    The connecting rod 16 comprises a main body 18 provided with holes 19 through which each finger 15 passes.
    The rod 16 advantageously comprises a sliding portion 20 shaped to cooperate with the closure member 14, as will be detailed later.
    The sliding portion 20 advantageously extends all along the periphery of the main body 18.
    Closing element The closure element 14 will now be described in more detail.
    According to the invention, the closing element 14 forms a guide for the connecting rod 16.
    As particularly visible in FIGS. 1 to 5, the closure element 14 comprises a slideway 30.
    The slide 30 comprises two rails 31, preferably identical and parallel to each other.
    The rails 31 extend in a longitudinal direction parallel to the uprights 4b of the frame 4.
    Advantageously, each of the rails has a general shape complementary to a movement of the connecting rod 16, as will be explained later.
    In the illustrated embodiment, each rail 31 has a generally undulating shape, that is to say that each rail has a succession of waves and valleys.
    Each rail 31 is delimited by two edges 32, 33.
    The edge 32 is rectilinear while the edge 33 describes the undulations of the rail 31.
    The two rails 31 are connected to each other by a base 34 disposed substantially orthogonally to the rails 31.
    As can be seen in FIG. 3, the base 34 protrudes on either side of the rails 31 so that a section of the slideway 30 has the general shape of an inverted π, or in other words, thus forming a groove .
    The base 34 has a rectangular shape delimited by two edges 35 and 36 extending parallel to the edges 32, 33 of the rails 31. The closure element 14 also comprises a wall 37 for closing the bearings 13.
    The wall 37 has a generally rectangular shape delimited by the edge 35 of the base 34 and a second edge 38, opposite the edge 35.
    As can be seen in FIG. 3, a section of the wall 37 extends orthogonally to the base 34 in a direction away from the rails 31.
    As also apparent from FIG. 3, the pin 10 is framed by the base 34 and the closure wall 37. The closure element 14 also comprises a wall 39 that bears on the frame 4.
    As is clear from Figure 3, seen in section, the support wall 39 and the closure wall 37 form an inverted T.
    The wall 39 is delimited by two longitudinal edges 40, 41.
    The inverted T is joined to the inverted π by the edge 35 of the base 34.
    The support wall 39 is placed against a frame portion 42 of the frame 4.
    Preferably, the edge 40 is held against another frame portion 43 of the frame 4.
    The wall 39 keeps the closure element 14 in position in the frame 4.
    Guide the connecting rod by the closing element
    The displacement of the connecting rod 16 is controlled by the actuator 7 via the lever 17.
    In the illustrated embodiment, the connecting rod 16 describes a partially circular trajectory. This is why the edges 33 of the rails 31 are corrugated, so as to match the movements of the connecting rod 16.
    As can be seen from the figures, the connecting rod 16 moves along the corrugations of the rails 31, the portion 20 being positioned between the two corrugated edges 33.
    Advantageously, the periphery of the main body 18 of the connecting rod 16 bears on the corrugated edges 33.
    Thus, the slide 30 guides the connecting rod 16, which avoids any deviation of trajectory.
    The slide 30 forms a groove, while the two rails 31 each form a rib on which the rod 16 moves, so as to rotate the flaps 3 from the closed position to an open position. We can also say that the sliding portion 20 corresponds to a rib sliding in the groove formed by the slide 30.
    Solidarity of the retaining element to the frame
    As particularly visible in Figure 4, the system 1 comprises a retaining means 45 of the closure element 14 to the frame 4.
    In the illustrated embodiment, an end 46 of the closure member 14 is shaped to form the retaining means 45.
    One end 47 of the edge 36 of the base 34 forms a tab 48.
    The tab 48 is disposed spaced and facing one end 49 of the rails 31.
    The support 12 of the bearings 13 is sandwiched between the tab 48 and the end 49.
    In a variant, a frame portion 50 of the frame 4 is clamped between the tab 48 and the end 49.
    As shown in Figure 4, a free end 51 of the lug 48 comprises a lug 52 for holding the lug 48 against the frame 4. The holding lug 52 is placed against an inner face 53 of the upper cross member 4a.
    Advantageously, the end 49 folds into a bearing wall 54 against an outer face 55 of the upper cross member 4a.
    It should be noted that the system 1 is advantageously devoid of screws for securing the closure element 14 and the frame 4.
    The fastening element 14 and the frame 4 are secured by the support wall 39 of the closure element 14 against the framework frame 4 and / or by the retaining means 45.
    The invention also relates to a manufacturing method of the management system 1.
    This method preferably comprises a step of insertion of the closure element 14 in the frame 4.
    This insertion step, illustrated in Figure 5, is performed by translating the closure element 14 between the rod 16 and the frame 4, in a direction parallel to the uprights 4b.
    It can thus be seen that the mounting method of the system 1 is particularly simple.
    Note also that once the closure element in place, it is held in position by the support wall 39 and its end 46 forming retaining means 45.
    Thus, it is not necessary to provide additional fastening means, such as screws.
    Advantages
    The management system according to the present invention has many advantages, and in particular the guidance of the connecting rod to avoid any misplacement of trajectory and thus ensuring an optimized operation of the shutters.
    In addition, the system according to the present invention is advantageously without screws, which greatly simplifies its manufacturing process and reduces costs.
    It is added that the same part preferably incorporates three functions: the closure element makes it possible to close the bearings, to guide the connecting rod and to fix itself to the frame.
