Definitions

• the invention relates to an air intake management device for a motor vehicle.
• a device may comprise a shutter device, sometimes called active calender shutter, or controlled air intake module.
• AGS active calender shutter
• controlled air intake module Such a device is most often referred to by the acronym AGS, derived from the English language expression "Active Grid Shutter”.
• AGS active Grid Shutter
• the device makes it possible to open or close the air access via a motor vehicle grille. In the open position, the air can circulate through the shell and participate in cooling the engine of the motor vehicle. In the closed position, the air does not enter via the grille which reduces drag and thus reduces fuel consumption and CO 2 remission.
• the AGS therefore reduces energy consumption and pollution when the engine does not need to be cooled by outside air.
• An AGS conventionally comprises an actuator (also called an actuator) controlling the flaps for opening or closing the air inlet.
• the shutters and the frame of the AGS supporting these shutters are usually made of plastic. This material has the advantage of being light and cheap.
• the plastic deforms or breaks easily, dampening the shock and reducing the risk of major damage. It is nevertheless preferable not to damage the AGS.
• the actuator is a relatively expensive device, which is also very dense. In case of shock, the actuator is often damaged resulting in significant repair costs.
• the actuator is likely to cause more serious injuries than those that can be caused by the only parts of the AGS.
• the invention aims to improve the situation.
• the invention relates in particular to an air intake management device for a motor vehicle, comprising: a flexible sheath for guiding the incoming air by a motor vehicle grille and a shutter device fixed in the flexible sheath, the air inlet management device being shaped to be fixed in a motor vehicle via the flexible sheath, the shutter device then being suspended in the motor vehicle via the flexible sheath.
• Such an air intake management device is advantageous in particular in that in case of impact, in particular of shock at low speed, the flexible sheath is deformed and can thus absorb the energy resulting from the shock by avoiding causing damage to the shutter device. Moreover, the fact of suspending the shutter device protects it from vibrations coming for example from the road or motor of the motor vehicle.
• flexible sheath it is understood that the sheath is sufficiently rigid to maintain the AGS in normal condition (or before impact) and sufficiently flexible to allow the retreat of the closure device in case of shock and a possibility of return at the initial position if needed.
• the flexible sheath is able to maintain the AGS and able to deform, without breaking, to allow the retreat of the AGS.
• the sheath may also be able to deform so as to return to an initial position following a shock.
• Certain thermoplastic polymers such as polypropylene and ethylene-propylene-diene monomer, have such properties.
• the invention also relates to an air inlet management device in which the flexible sheath is overmolded on the closure device.
• the invention also relates to an air intake management device in which the flexible sheath is snapped onto the closure device.
• the invention also relates to an air intake management device in which the flexible sheath is made of thermoplastic polymer, in particular polypropylene or ethylene-propylene-diene monomer.
• the invention also relates to an air intake management device in which the flexible sheath is shaped to be fixed at one end to the shell of a motor vehicle.
• the invention also relates to an air inlet management device in which the flexible sheath is shaped to be fixed at one end to a radiator support or an exchanger cassette.
• FIG. 1 illustrates a longitudinal vertical section of a motor vehicle equipped with an air intake management device according to one embodiment of the invention
• FIG. 2 illustrates a vertical longitudinal section of a crashed motor vehicle equipped with an air intake management device according to one embodiment of the invention.
• Figure 1 illustrates a vertical section of a motor vehicle in a longitudinal direction of the vehicle.
• the vehicle comprises a bumper beam 1 above and below which are placed front face grids 2. These grids are fixed, they remain in the open position.
• the vehicle also comprises a flexible sheath 3, surrounding a closure device 4 (AGS) attached to this flexible sheath.
• AGS closure device 4
• the flexible sheath 3 guides the incoming air through the grille (via the grids 2) to the AGS 4, and guides the air leaving the AGS to the condenser 5.
• the flexible sheath is fixed to the support 6 of radiator 7 (commonly called bolster or bulkhead of English).
• Figure 2 shows a motor vehicle identical to that shown in Figure 1, but which is involved in an accident. This shows that the vehicle hits an obstacle 8 located under the bumper beam 1. The shock resulting from this accident deforms the bottom of the flexible sheath 3 and displaces the AGS 4. However, the AGS 4 is intact and can easily be put back in place after repairing the bodywork damaged by the accident.
• a first embodiment relates to an air intake management device for a motor vehicle.
• This device comprises a flexible sheath 3 for guiding the incoming air by a motor vehicle grille.
• a closure device 4 is fixed in the flexible sheath 3.
• the air intake management device when the air intake management device is installed in a motor vehicle, and when the motor vehicle moves, the air entering through the front of the vehicle (due to the relative speed of the vehicle relative in air) is guided by the flexible sheath 3 towards the closure device 4.
• shut-off device 4 If, on the other hand, the shut-off device 4 is in the open position (in order to increase the cooling of the engine), the flow of air continues its way to the radiator 7 while being guided by the flexible sheath 3. Such a flow of air causes greater drag. It therefore increases the fuel consumption of the motor vehicle and the CO 2 emissions.
• the air intake management device is shaped to be fixed in a motor vehicle via the flexible sheath 3.
• the shutter device 4 is then suspended in the motor vehicle via the flexible sheath 3, instead of being directly attached to a rigid element of the motor vehicle. This protects the closure device 4 in the event of impact (insofar as this shock is dampened by the flexible sheath). This also protects the elements of the motor vehicle to which the shutter device is usually attached. Indeed, when the energy of a shock is transmitted to the closure device of the state of the art, it is also transmitted to the elements to which the closure device is fixed rigidly.
• the fixing being carried out by suspension instead of a rigid fixation, the transmission of the energy of the possible shocks is thus prevented or at least damped, even if it propagates to the shutter device .
• This avoids, in the event of a shock, the loss of mechanical parts that would come off the closure device 4 and / or element (s) to (s) which (s) this shutter device was in the state of the art fixed rigidly.
• the shutter device 4 can be moved due to the deformation of the flexible sheath 3. In general, such a displacement of the shutter device 4 does not damage it (in the case of shocks at low speed ). It then suffices to replace the closure device 4 by replacing the flexible sheath 3 in its original position, after repairing the body elements (or other) possibly damaged.
• Suspending the shutter device 4 also protects this shutter device vibration.
• the vibrations which may for example come from the fans, the motor vehicle engine, or the road, are filtered by the flexible sheath 3, which operates a form of decoupling. This can contribute to the reduction of the noticeable noise inside the vehicle, as well as to the reduction of the wear of the parts (in particular those constituting the shutter device 4).
• the flexible sheath 3 of an air intake management device according to the first embodiment is overmolded on the closure device 4.
• the flexible sheath 3 of an air intake management device is snapped on the closure device 4.
• the flexible sheath comprises a circumferential groove located in a plane perpendicular to a longitudinal axis of the flexible sheath. This groove is located on the inner face of the flexible sheath. It is shaped to cooperate with a corresponding flexible tongue arranged along a periphery of the closure device.
• the sheath comprises several grooves of the aforementioned type, spaced apart from each other, and shaped to cooperate with a plurality of corresponding parallel flexible tabs located on a periphery of the closure device.
• Other forms of grooves and flexible tongues are possible.
• These flexible tongues may consist of protrusions formed in said flexible sheath.
• the flexible sheath 3 of an air intake management device is made of thermoplastic polymer. It can theoretically be made of natural rubber, or artificial, although this is often quite expensive.
• thermoplastic polymer of an air intake management device is a polypropylene, which has the particular advantage of being cheap, resistant to fatigue and bending, sparse and recyclable.
• thermoplastic polymer of an air intake management device is an ethylene-propylene-diene monomer (often referred to by its acronym EPDM), which presents in particular the advantage of being resistant to oxidation, bad weather, light, cold and acids.
