Definitions
- the present invention relates to a flap for a shutter device and more specifically to a device for shutting off the air intake of the front face of a motor vehicle.
- the front faces of motor vehicles are generally made up of two main air intakes 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 about 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.
- the shutters of such closure devices may in particular comprise an extruded shutter 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.
- each of the lips comprises at least three protrusions located on said inner face of the lip and configured to rest on the outer face of the wall of said shutter body when said at least one end piece is fitted with said body of shutter. Furthermore, each protuberance substantially has the shape of an gullet.
- the protuberances exert a force on the flap body so as to maintain the flap body between the core of the end piece and the protuberance.
- the protuberance exerts a force on the shutter body which then comes firmly into contact with the core body of the shutter end piece.
- the shutter body is thus clamped in force between the protrusion and the core of the end piece.
- the flap may also comprise one or more additional characteristics taken alone or according to all the technically possible combinations, among the following.
- the protrusion is formed integrally with the tip.
- the tip and the protrusion comprise a plastic material.
- the tip and the protrusion are made of a fiber reinforced plastic material.
- the tip and the protrusion are composed of fiberglass reinforced plastic.
- the end piece and the protrusion are made of plastic comprising 30% fiberglass, in particular polyamide GGFR30.
- the end piece is composed of two parts which fit into one another.
- the protuberances are spaced from each other by a spacing.
- the spacing between each protrusion included on a lip varies
- the spacing between each protuberance is identical
- the spacing between each protrusion varies on one of the two lips only.
- At least one lip comprises at least one opening so that a part of the shutter body is not in contact with said lip. In other words, at least part of the shutter body is free.
- the shutter body comprises at least one edge, preferably two edges.
- said edges correspond to the free parts described above.
- At least one lip comprises protrusions over its entire interior surface.
- At least one lip comprises an area with protrusions spaced by a spacing, and at least one area without protrusions.
- each of the lips includes an area with protrusions spaced by a spacing and at least one area without protrusions.
- the zone comprising protuberances is a central zone and the zones not comprising protuberances are ends of the lip.
- each of the lips comprises the same number of protrusions.
- each of the lips comprises a different number of protuberances.
- the protrusions which are on one lip face the protrusions of the other lip.
- the core of the end piece comprises at least a first and a second face, at least one of the two first or second faces comprising at least one material recess.
- the first and the second face both comprise recesses of material.
- the material recess is a blind hole.
- At least one protuberance faces a recess of material in the core.
- each protrusion has a height less than the height of the core.
- each protrusion has a base, a wall of a height h extending from this base and an apex at the end of the wall opposite the base, the base having a surface greater than the top surface.
- the protuberance is formed by the base, the wall, the top and the interior face of the lip on which it is located.
- the lips have a lower height than that of the core.
- the lips have a height J substantially equal to the height h of each protuberance.
- the core includes a base, a wall extending from the base, and a top, the surface of the base being greater than the surface of the top.
- the body of the shutter is produced by extrusion.
- the body of the shutter has a thickness of between 1 mm and 3 mm, preferably 2 mm.
- said at least one end piece is produced by injection molding.
- the invention also relates to a device for closing off a motor vehicle comprising at least one flap as described in the present application.
- the invention also relates to a front panel module for a motor vehicle comprising a closing device as claimed in the preceding claim.
- first element or second element as well as first parameter and second parameter or even first criterion and second criterion, etc.
- it is a simple indexing to differentiate and name elements or parameters or criteria that are close but not identical. This indexing does not imply a priority of one element, parameter or criterion over another and such denominations can easily be inverted without departing from the scope of the present description. This indexing does not imply an order in time either, for example to assess such or such criteria.
- Shutter 1 comprises a shutter body 10 and at least one end piece 11 configured to fit into said shutter body 10.
- Shutter 1 is part of a closure device 2 illustrated in the .
- the front faces of motor vehicles are generally made up of two main air intakes called the upper track and the lower track, 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 of the motor vehicle.
- the shutter device 2 is arranged in the air path passing through the main air inlets, more generally the lower path. It comprises a multiplicity of flaps 1 with flap bodies 10 pivotally mounted around parallel axes and capable of assuming a multiplicity of different angular positions, between an open position and a closed position, under the action of appropriate means of control.
- the shutter device 2 is thus similar to a louver 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 and by varying the quantity of air they receive.
- the flap bodies 10 in the closed position make it possible to reduce the drag coefficient of the vehicle and thus improve the aerodynamics of said vehicle.
- the obturation device 2 is illustrated in the .
- the axes of this trihedron can also correspond to the different orientations of the motor vehicle.
- the X axis can thus correspond to the axis of the length of the vehicle, the Y axis to the axis of its width and the Z axis to that of its height.
- Said closure device 2 comprises a support frame 20 comprising in particular two longitudinal crosspieces 20a, extending parallel to the Y axis of the trihedron, and at least two lateral uprights 20b, extending parallel to the Z axis of the trihedron, and connecting said longitudinal crosspieces 20a.
- the support frame 20 is made of plastic material and the two longitudinal crosspieces 20a and the at least two side uprights 20b are obtained by injection molding. In order to improve the rigidity of said support frame 20, the latter can be molded in one piece.
- the flap or flaps 1 When there is a plurality of flaps 1, the latter form rows of flaps 1 parallel to each other and which form a set of flaps 1 as illustrated in the figure.
- a control element 13 At one of the ends of the flap 1 or of all the flaps 1, is placed a control element 13 allowing the rotation of the flap or flaps 1 around a pivot axis A (illustrated on the at ), between an open position (not shown), where the flap or flaps 1 are arranged so that a flow of air can pass through the closure device 2, in particular inside the support frame 20, and a shutter position illustrated in , where the flap or flaps 1 are arranged so that an air flow cannot pass through the shutter device 2.
- the pivot axis A is parallel to the axis Y of the trihedron.
- a device 2 for closing off a motor vehicle front face air inlet comprising several sets of flaps 1 extending over the entire width of the support frame 20.
- the sets of flaps 1 can be separated by the control element 13 to ensure synchronous rotation.
- the control element 13 comprises a connecting rod (not shown) and an actuator (not shown) configured to apply to the connecting rod a translational movement along the axis Z of the trihedron.
- the actuator can be electric or pneumatic.
- a flap 1 comprises a flap body 10 and two end pieces 11 configured to fit into said flap body 10.
- the flap body 10 of the flap 1 is described in detail below.
- the shutter body 10 is elongated along its pivot axis A and of length L.
- the shutter 1 comprises two ends 10a configured to each receive an end piece 11.
- the shutter body 10 comprises a cross section 10s of width l.
- the cross section 10s of the shutter body 10 may more particularly have a substantially oval profile. It is nevertheless quite possible to imagine other shapes for the profile of the cross section 10s of the shutter body 10, such as for example rectangular or even with a hollow central portion from which fins start.
- the shutter body 10 comprises a wall 30 which comprises an outer surface 31 and an inner surface 32, said inner surface defining an internal cavity 33.
- the wall 30 of the shutter body 10 is produced by material extrusion.
- this material is a metallic material. This allows said wall to have a thickness between 0.1 and 2.5. In a non-limiting alternative embodiment, the thickness is between 0.2 and 0.3 mm. In another non-limiting embodiment, the material is a thermoplastic polymer. This allows said wall to have a thickness of between 0.5 and 1 mm.
- the thickness is between 0.5 and 3 mm, preferably between 0.8 and 2.5 mm, preferably between 0.8 and 2 mm.
- the thermoplastic polymer is polypropylene.
- the flap is made of PPGF30, polyamide, or any other material suitable for extrusion. It is an economical material.
- the internal cavity 33 is defined by the internal surface of the wall 30. It will be noted that a shutter body 10 thus extruded makes it possible to reduce the mass of the shutter 1 compared to a solid shutter body, generally of omega section and obtained by plastic injection.
- the flap 10 further comprises at least one edge 34.
- it comprises two edges 34.
- the edges 34 are solid as illustrated in the .
- the edges 34 can also be hollow, bordered by a junction element.
- the edges 34 correspond to the ends of the cross section 10s of the shutter body 10. They extend parallel to the pivot axis A. They allow good sealing when the shutter body 10 is in a position of filling. Indeed, in the case where there are several shutters 1 in the shutter device 2, the edges 34 will be in contact with the edges 34 of the adjacent shutter bodies 10 which are on either side of the shutter body.
- the flap 1 comprises a single internal cavity 33 defined by the internal surface 32 of the wall 30 of the flap body and the edges 34 when these are full.
- end pieces 11 At each end 10a of the shutter body 10 are arranged end pieces 11.
- the end pieces 11 can be of different shape or else be of identical shape, which makes it possible to save on production costs.
- the end pieces 11 are molded with said shutter body 10. This makes it possible to simplify the assembly of the shutter 1.
- an end piece 11 is made of polyamide.
- a tip 11 is made of polyamide reinforced with glass fibers, it is for example the material PA66 GF30 which is a polyamide reinforced with 30% glass fiber. End pieces 11 are preferably made by injection molding.
- an end piece 11 comprises a protrusion, otherwise called a core 35, projecting parallel to the pivot axis A in order to be embedded in the internal cavity 33 of the shutter body 10.
- the core 35 makes it possible to drive the shutter 1 during of its operation.
- the core 35 makes it possible to fit the endpiece 11 into the internal cavity 33 of the shutter body 10.
- the end pieces 11 comprise at least several protrusions 36.
- the protrusions 36 are configured to rest on the outer surface 31 of the body 10 of the shutter.
- the protrusions 36 thus ensure that the shutter body 10 is held in the endpiece 11.
- the protrusions 36 are formed in one piece with the endpiece 11.
- the endpiece 11 and the protuberances 36 are for example made of plastic material, reinforced with glass fibers such as GGFR30.
- the end piece comprises two separate lips 37 facing each other, located on either side of the core35.
- Each lip 37 comprises a curved portion comprising an inner face 39 and an outer face 38, the protrusion 36 being located on said inner face 39 of the lip 37.
- the protrusions 36 are spaced from each other by a spacing 40. In the embodiment shown in Figures 5 and 6, the spacing 40 between each protrusion 36 is identical.
- the protrusions 36 are located substantially on the central part of each of the lips 37.
- the ends of the lips 37 do not include protrusions 36.
- the protrusions 36 could be present over the entire inner surface 39 of each of the lips.
- each lip includes the same number of protrusions 36. In an embodiment not shown here, each lip could include a different number of protrusions 36. In an embodiment not represented here, it would be possible for only one lip to comprise protuberances, or for one of the two lips to have only a single protuberance.
- the lips 37 comprise an opening 41 so that part of the shutter body 10 is left free, in particular the part comprising the stop 34. This makes it possible to ensure the tightness of the device comprising the blind.
- the protuberances 36 present on one of the lips 38 face the protuberances 36 located on the second lip 38.
- the core 35 of the endpiece 11 comprises at least a first 42 and a second 43 face, at least one of the two first 42 or second 43 comprising at least one material recess 44.
- each of the first 42 and second 43 faces comprise several recesses of material 44 having the shape of blind holes.
- each protuberance 36 faces a material recess 44 of the core 35.
- the protrusions 36 have a height h less than the height H of the core 35.
- each protrusion comprises a base 45, a wall 46 of a height h extending from this base 45 and a top 47 at the end of the wall 46, the base 45 having a surface greater than the surface of the top 46.
- the protuberance 36 has the shape of an gully or a half-cone, which facilitates the insertion of the body 10 of the shutter in the hub 11.
- the core 35 includes a base 48, a wall 49 and a top 50, the base 48 of the core 35 having a surface greater than the surface of the top 50 of the core 35.
- the core has thus a form of vent also so as to facilitate the insertion of the shutter body.
- the lips 36 have a height J less than the height H of the core 35. This ensures better retention of the shutter body without adding unnecessary stresses.
- the height J of the lips 37 is substantially equal to the height h of the protrusions 36.
