Definitions
- the present invention relates in particular to a closure device frame for a motor vehicle, in particular for a motor vehicle front end air intake closure device, also called an AGS (Active Grill Shutter) device, active grid shutter).
- AGS Active Grill Shutter
- Such a frame is made in a known manner plastic material.
- this type of implementation is unsatisfactory.
- the invention aims in particular to further improve the rigidity of the frames of such a closure device.
- the subject of the invention is thus a frame for a closure device for a motor vehicle, in particular for a motor vehicle front end air intake closure device, comprising:
- At least one insert at least partly made of composite material
- a body based on a plastic material at least partially coating the insert.
- the frame has a greater rigidity due to the inserts or composite material. This can be particularly advantageous in the event of an impact at the front of the vehicle.
- the composite material of the insert comprises reinforcing fibers, these reinforcing fibers being in particular of a material chosen from glass, carbon, and a mixture of these materials.
- the frame comprises a plurality of distinct inserts.
- the inserts are assembled together, in particular by being welded together.
- the frame comprises a single insert.
- the insert is in the form of a sheet, in particular a pre-cut sheet.
- the insert or inserts extend over a majority of the length of the frame.
- the insert or inserts extend over at least a portion of a periphery of the frame, particularly around the periphery.
- the insert is at least partially folded defining a cavity arranged to receive a portion of the plastic-based body, this portion for example comprising reinforcing ribs.
- the plastic-based body comprises besides the plastic material, also a filler such as glass fibers and / or carbon.
- the invention also relates to a closure device for a motor vehicle, in particular a closure device for front air intake of a motor vehicle, comprising:
- one or more shutters arranged to be able to pivot between at least one open position and one closed position.
- the device comprises at least one actuator adapted to control the pivoting of the flap relative to the frame, preferably around a longitudinal axis of the flap.
- the invention also relates to a method of manufacturing a card as defined above, comprising a step of producing a frame with at least one insert at least partly made of composite material.
- Figure 1 shows schematically in longitudinal section a front portion of a motor vehicle
- FIG. 2 illustrates an exemplary device for closing the air inlet of the front face of a motor vehicle
- FIG. 1 schematically illustrates in longitudinal section the front portion of a motor vehicle 10.
- This motor vehicle 10 is provided with a heat exchange device 12 disposed between one or more grids 14, fixed on the vehicle body automobile, and the engine 16 of the motor vehicle.
- the grids 14 are here separated horizontally by the bumper 18 of the motor vehicle 10.
- a device 20 for closing the front air inlet of the motor vehicle is disposed in the path of this air flow, upstream of the heat exchanger 12, closer to the grids 14.
- such a closure device 20 comprises a frame 22 comprising at least one opening 24, here two openings 24, and flaps 26, pivotally mounted along an axis X on the frame 22 to selectively close the openings 24.
- the pivoting of the flaps 26 allows more or less air to pass through the grids 14, to the heat exchanger 12, depending on the needs of the latter and / or the speed of the motor vehicle. Indeed, by plugging the grids 14, it is possible to improve aerodynamics of the motor vehicle and, thus, to limit fuel consumption, especially at high speeds.
- the flaps 26 are generally made of plastic material, the flaps 26 being for example injection molded.
- the pivoting of the flaps 26 is controlled by actuators transmitting a pivoting torque to the flaps 26, generally at a longitudinal end of the flap.
- the frame 22 comprises:
- a body 37 made of plastic material coating the inserts 30-35, the plastic material can be loaded.
- the composite material of the inserts comprises reinforcing fibers, these reinforcing fibers being made of a material chosen from glass, carbon, and a mixture of these materials.
- the inserts 30-35 comprise in the example described:
- inserts 34 and 35 disposed between the other four inserts 30-33.
- the inserts can be assembled together, being welded together.
- These inserts 30-35 are then placed in a mold in which the body 37 is overmolded on the inserts to form the frame 22.
- the frame 22 comprises a single insert 40.
- This insert 40 is in the form of a pre-cut sheet.
- This insert 40 comprises openings 45 defining the future openings of the frame 22.
- This insert 40 extends over a majority of the length of the frame 22, and around the frame 22.
- This insert 40 is locally folded to define a cavity 41 arranged to receive a portion of the plastic-based body 37, this portion comprising reinforcing ribs 42.
- the plastic-based body 37 comprises in addition to the plastics material, also a filler such as glass and / or carbon fibers.
