Definitions
- the present invention relates to a shutter for a shutter device and more specifically a motor vehicle front face air inlet shutter device.
- the front faces of motor vehicles are generally made up of two main air inlets called the high way and the low way, separated by a bumper beam. Behind this bumper beam are generally placed the heat exchangers of the motor vehicle, such as the one used for the air conditioning of the passenger compartment and/or the one used for cooling the engine.
- a support frame comprising a multiplicity of flaps mounted pivoting around parallel axes and capable of taking a multiplicity of different angular positions, between an open position and a closed position, under the action of appropriate control means.
- a shutter device similar to a jalousie is thus obtained which makes it possible to adjust the flow of air passing through the air inlets and arriving at the heat exchangers. It is thus possible to optimize the efficiency of these heat exchangers according to the needs by varying the quantity of air they receive.
- the flaps in the closed position make it possible to reduce the drag coefficient of the vehicle and thus improve the aerodynamics of said vehicle.
- the flaps of such closure devices may in particular comprise an extruded flap body at the ends of which are arranged end pieces allowing the connection with the support frame.
- end pieces in order for these end pieces to remain in place within the shutter body or else in order to prevent the end pieces from damaging the shutter body when they are put in place, reduced manufacturing tolerances are necessary. This quality of production is difficult to achieve and very expensive given the materials and dimensions of the parts.
- One of the aims of the present invention is therefore to remedy at least partially the drawbacks of the prior art by proposing a shutter comprising an improved connection between the shutter body and the end pieces.
- the present invention therefore relates to a flap for a motor vehicle front face air inlet shutter device, said flap comprising a profiled oblong-shaped flap body, obtained by extrusion and extending along its axis of rotation, said shutter body comprising two walls external parts connected edge to edge and delimiting an internal hollow, the said shutter further comprising at each of the ends of the shutter body an end fitting, the said end fittings comprising an internal part inserted into the hollow of the shutter body and an external part protruding from the said flap body, the flap body comprising, within its hollow, two reinforcing side walls extending parallel to the axis of rotation and connecting the internal faces of the external walls, the internal part of at least one end piece comprising at least a first and a second oblique tooth projecting outwards from said internal part, the end of the at least one first tooth being intended to come into contact with a side wall and the end of the at least one second tooth being intended to come into contact with the other side wall, the teeth being oriented so as to varnish to oppose
- the side walls divide the hollow of the shutter body into three, a side channel at each edge of the cross section of the shutter body and a central channel disposed between the two side channels , the inner part of the tip being disposed within said central channel.
- the central channel comprises a central reinforcing wall extending along the axis of rotation and connecting the internal faces of the external walls, said central wall separating the central channel into two , the inner part of the endpiece comprising an insertion slot (305) of said central wall.
- the internal part of the end piece comprises at least one point of support on each of the internal faces of the external walls forming the shutter body.
- the internal part of the end piece has a cross section of complementary shape to that of the hollow of the shutter body.
- the internal part of the end piece comprises non-through recesses facing the internal faces of the external walls in the state mounted in the shutter body.
- the thickness of the sections forming the internal part of the end piece varies by a value of less than 15% from one section to another.
- the internal part of the end piece comprises a keying through hole arranged asymmetrically on said internal part.
- the end piece comprises between its internal part and its external part a flange projecting perpendicularly to the axis of rotation of the flap, said flange closing the end of the flap body.
- the shutter comprises, at a first of its ends, an end piece comprising on its outer part a pivot axis concentric with the axis of rotation and, at a second end, an end piece comprising a pivot axis concentric with the axis of rotation and a control arm.

- Figure 7 shows a schematic representation in perspective and in longitudinal section of a shutter end.
- first element or second element as well as first parameter and second parameter or even first criterion and second criterion, etc.
- first criterion and second criterion etc.
- Figure 1 shows a schematic representation in perspective of a shutter device in the shutter position. This figure 1 shows more exactly the outer face of said closure device 1, that is to say the face facing the outside of the motor vehicle.
- Said closure device 1 comprises a support frame 5 comprising in particular two longitudinal crosspieces 5a, extending parallel to the axis Y of the trihedron, and at least two side uprights 5b, extending parallel to the axis Z of the trihedron, and connecting said longitudinal crosspieces 5a.
- the support frame 5 is made of plastic material and the two longitudinal crosspieces 5a and the at least two side uprights 5b are obtained by injection molding. In order to improve the rigidity of said support frame 5, the latter can be molded in one piece.
- the closure device 1 comprises 2 sets of flaps 3 separated by a control module 13.
- the set of flaps 3 having the greatest length along the Y axis rests on an intermediate upright 5c arranged in the opening of the support frame 5 in order to limit the deformation of the flaps 3 under their own weight and a possible disengagement at the level of their connections with the support frame 5 or the control module 13.
- This control module 13 is placed at one of the ends of the sets of flaps 3 so as to allow the synchronous rotation of said flaps 3 around a pivot axis A.
- This rotation is performed between an open position (not shown), where the flaps 3 are arranged so that a flow of air could isse pass through the shutter device 1, in particular inside the support frame 5, and a shutter position illustrated in Figure 1, where the shutters 3 are arranged so that an air flow cannot cross the shutter device 1.
- control module 13 is arranged in the opening of the support frame 5 and is connected to two sets of flaps 3 arranged on either side of said control module 13. It is nevertheless quite possible to imagine that the control module 13 is arranged at the level of one of the side uprights 5b and is thus connected to only one set of flaps3.
- the control element 13 comprises in particular a connecting rod 7.
- the flaps 3 comprise a control arm 39, perpendicular to their pivot axis A and carrying a connecting pin along a connecting axis B.
- the connecting stud allows the connection between the flap 3 and the connecting rod 7
- the pivot axis A and the connecting axes B are not coincident and both parallel to the axis Y of the trihedron.
- the control module 13 also includes an actuator 9.
- the actuator 9 can be electric, such as an electric motor or even pneumatic, such as a pneumatic cylinder. Said actuator 9 applies to the connecting rod 7 a translational movement along the Z axis of the trihedron, by pivoting a lever 11.
- the flaps 3 can each pivot about a pivot axis A defined by their connection with the support frame 5.
- the connecting studs between the flaps 3 and the control rod 7 are eccentric with respect to the pivot axes A so that a translation movement parallel to the Z axis of the trihedron of the control rod 7, under the action of G actuator 9, causes the flaps 3 to pivot about their respective pivot axes A and therefore the passage of said flaps 3 from one position to another.
- the flaps 3 being connected to the same connecting rod 7, the passage from an open position to a closed position is synchronous for all said flaps 3.
- a shutter 3 comprises a shutter body 31 of profiled oblong shape, obtained by extrusion and extending along its axis of rotation A.
- the cross section of the shutter body 31 can more particularly have a substantially oval profile (see Figure 4).
- ends 30, 30 ' At each end of the shutter body 31 are arranged ends 30, 30 '.
- end pieces 30, 30' make it possible in particular to close the shutter body 31 obtained by extrusion and also allow the connection of the shutter 3 with the support frame 5 and the control module 13.
- the end piece 30' intended to be connected to the control module 13 comprises in particular the control arm 39 allowing the connection with the connecting rod 7 (see FIGS. 2 and 3).
- the shutter body 31 has two outer walls 310 connected edge to edge and delimiting an internal hollow 311. These two external walls 310 more exactly form the external structure of the shutter body 31.
- the internal hollow 311 extends over the entire length of the shutter body 31 because the latter is made by extrusion.
- the flap body 31 comprises more particularly within its hollow 311, two side walls 312 of reinforcement extending parallel to the axis of rotation A and connecting the internal faces of the external walls 310. These side walls 312 make it possible in particular to stiffen the structure of the shutter body 31.
- These side walls 312 may in particular be straight and parallel to one another.
- the side walls 312 can divide the hollow 311 of the shutter body 31 into three and form a side channel at each edge of the cross section of the shutter body 31 and a central channel disposed between said two side channels.
- the end pieces 30, 30' comprise an internal part 300 inserted into the hollow 311 of the shutter body 31 and an external part 301 protruding from said shutter body 31.
- the end pieces 30, 30' can also comprise, between their part 300 and their outer part 301, a flange 302 projecting perpendicularly to the axis of rotation A of the flap 3. This flange 302 closes in particular the end of the flap body 31.
- the flange 302 also makes it possible to protect the support frame 5 and the control module 13 of the water or dust that could arrive at the level of the shutter body 31.
- the shutter 3 comprises in particular an end piece 30 comprising on its outer part 301 a pivot axis concentric with the axis of rotation A intended to cooperate with a bearing carried by the support frame 5.
- the shutter 3 comprises another end piece 30' comprising a pivot axis concentric with the axis of rotation A intended to cooperate with a bearing carried the control module 13 and the control arm 39.
- the internal part 300 of the end pieces 30, 30' can more particularly be arranged within the central channel of the shutter body 31.
- the end pieces 30, 30' are preferably made of plastic by injection molding.
- the inner part 300 of the endpiece 30 comprises at least a first tooth 303 and a second tooth 303 'oblique and projecting outwardly from said inner part 300
- the end of the at least one first tooth 303 being intended to come into contact in a side wall 312 of the shutter body 31 and the end of the at least one second tooth 303' being intended to come into contact of the other side wall 312 of the shutter body 31.
- the teeth 303, 303' are more particularly oriented so as to varnish to oppose the extraction of the tip 30 from the shutter body 31.
- the base of the teeth 303, 303', connecting them to the inner part 300 is at a greater distance from the outer part 301 than the end of said teeth 303, 303'.
- the ends of the teeth 303, 303' are therefore oriented in the direction of the internal part 301.
- the endpiece 30 comprises two series of three teeth 303, 303 'arranged on either side of its internal part 300.
- the teeth 303, 303' can in particular come of material with the internal part 300 of the tip 30.
- teeth 303, 303' allow a good connection between the endpiece 30 and the flap body 31. This makes it possible to secure the endpiece 30 within the hollow 311 of the flap body 31 and limits the risks that the latter comes off. Moreover, these teeth 303, 303', thanks to their deformation, allow tolerances of manufacturing between the tip 30 and the shutter body 31 and an easy insertion of the tip 30 within said shutter body 31.
- the inner part 300 of the endpiece 30 may also comprise recesses 304 not passing through and facing the inner faces of the outer walls 310 in the state mounted in the shutter body 31. These recesses make it possible in particular to reduce the amount of material constituting the end piece 30 and thus makes it possible to reduce its weight.
- the sections forming the internal part 300 of the end piece 30 can in particular vary by a thickness of a value less than 15% from one section to another. This relatively constant thickness of the sections of the internal part 300 also allows the tip 30 to have a relatively uniform thermal inertia.
- the inner part 300 of the endpiece 30 may further comprise a keying through hole 306 arranged asymmetrically on said inner part 300.
- asymmetrically is meant here that this keying hole 306 is arranged in a side or another of the axis of rotation A.
- This keying hole 306 makes it possible, for example, during an automated assembly process, to determine the direction and orientation of the end piece 30 for assembly.
- the central channel of the hollow 11 of the shutter body 3, in which the internal part 300 of the endpiece 30 is inserted may also comprise a central reinforcing wall 313 extending along the axis of rotation A , as illustrated in Figures 4, 6 and 7.
- This central wall 313 separates the central channel of the hollow 311 in two.
- the central wall 313 also makes it possible to stiffen the shutter body 31 and in particular to maintain the gap between the external walls 310. For this, this central wall 313 more particularly connects the internal faces of the external walls 310.
- the internal part 300 of the end piece 30 may in particular comprise an insertion slot 305 of said central wall 313 in order to allow the insertion of the internal part 300 in the central channel of the shutter body 31.
- the inner part 300 of the endpiece 30 may comprise at least one fulcrum on each of the inner faces of the outer walls 310 forming the shutter body 31.
- This allows in particular the inner part 300 and more broadly to the end piece 30 to have only one degree of freedom along the axis of rotation A. This notably allows good connection between the shutter body 31 and the end piece 30.
- the internal part 300 of the end piece 30 may in particular have a cross section of a shape complementary to that of the hollow 311 of the shutter body 31 .
