专利说明:
AGS WITH ACTUATOR DEPORTE The invention particularly relates to an air inlet control device. Such a device is sometimes referred to by the acronym AGS, derived from the English expression "Active Grille Shutter". The device makes it possible to open or close the access of air to an engine compartment via a set of flaps arranged on the front face of the motor vehicle. In the open position, the air can circulate through the air intake, and participate in the cooling of the engine of the motor vehicle. In the closed position, the air does not enter via the front grille or front bumper, reducing the drag coefficient and thus reducing fuel consumption and CO2 emissions. The AGS device therefore reduces energy consumption and pollution when the engine does not need to be cooled by outside air. A front-end module, or front-end structure, for a motor vehicle comprises a front-end support (better known by the English term bolster) which generally comprises an upper cross-member secured to a lower cross-member by means of two legs arranged vertically in the motor vehicle. In known manner, such a module for the front face can extend in the motor vehicle of a shield to a deck of the vehicle and allow to secure a motor compartment, to support a motor fan assembly while constituting a separation of the cabin of the vehicle. It is useful when designing a motor vehicle to ensure that the consequences of an accident in which the motor vehicle collides with an obstacle are minimized. In particular, it is necessary to reduce the risk of bodily injury (in particular when a pedestrian is overturned by the motor vehicle) but also to reduce the material damage to the motor vehicle itself. An AGS device conventionally comprises an actuator (also called actuator) controlling the flaps for opening or closing the air inlet. The shutters and the frame of the AGS device supporting these shutters are usually made of plastic. This material has the advantage of being light and cheap. In addition, in the event of a shock, the plastic deforms or breaks easily, dampening the shock and reducing the risk of major damage. In contrast, the actuator is a relatively expensive device, which is also very dense. In the event of an impact, the actuator is often damaged, resulting in significant repair costs. In addition, in the event of a collision with a pedestrian, the actuator is likely to cause more serious injuries than those that can be caused by the only parts of the AGS device. The object of the invention is to at least partially overcome these disadvantages. The invention relates in particular to an air intake control device of a front-end module for a motor vehicle, comprising: flaps, an actuator, for example an electric actuator, arranged to control the flaps, and a flexible connection connecting the electric actuator to the flaps adapted to deport the actuator to prevent, during a collision of the motor vehicle with an entity, that the actuator does damage to said entity. Such a device is doubly advantageous. It allows on the one hand to minimize damage to third parties, and on the other hand to minimize damage to the air inlet control device and in particular to the actuator, by fixing the actuator in a protected area. This zone may be remote from the flaps of the device, located at the front of the vehicle, often impacted first in the event of an accident. Other embodiments of the air inlet control device propose that: the flexible connection comprises a cable; the flexible connection comprises a rod. The invention also relates to a front-end module for a motor vehicle, comprising: - a protection element, - an air inlet control device as described above, - in which the actuator is fixed on the element protection element, this protection element being for example located between the actuator and the flaps. Other embodiments of the front-end module for a motor vehicle propose that: the protection element is a bumper beam; - A first set of flaps is located above the bumper beam and a second series of flaps is located below the bumper beam, the actuator being arranged to independently control the two sets of flaps; the module comprises a radiator support and a radiator, the radiator support constituting the protection element; - The module includes a radiator and a cap attached behind the radiator for channeling air that has passed through the radiator, wherein the actuator is fixed inside the cap. 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: - Figures 1 to 3 illustrate AGS devices according to the state of the art; FIG. 4 illustrates an AGS device and a front-end module for a motor vehicle according to a possible embodiment of the invention; FIG. 5 illustrates an AGS device and a front-end module for a motor vehicle according to another possible embodiment of the invention. In these figures, substantially identical elements have the same references. The following achievements are examples. Although the description refers to one or more embodiments, this does not necessarily mean that each reference relates to the same embodiment, or that the features apply only to a single embodiment. Simple features of different embodiments may also be combined to provide other embodiments. Figure 1 illustrates, in the form of a longitudinal section, a front face structure portion of a vehicle comprising an air intake control device AGS located in front of a radiator RAD. An AGS device for controlling, or closing, the air intake of a front face for a motor vehicle comprises an assembly comprising a support frame defining the air inlet and a set of shutters able to close said inlet 'air. The device AGS is provided with a P_ACT actuator here comprising two sub-elements (which may be two autonomous actuators, forming together the actuator of the AGS device). A bumper beam ("bumper beam" in English) BUB is placed in a horizontal plane of the motor vehicle, perpendicularly to a longitudinal axis of the vehicle. A first sub-element is located above the bumper beam BUB and controls a series of flaps P_SHT1 located above said beam. A second sub-element of the actuator P_ACT is located beneath the bumper beam BUB and controls a series of flaps P_SHT2 located below said beam. The elements of the actuator P_ACT are located at the level (in the immediate vicinity) of the flaps that they fly. These elements of the P_ACT actuator, which are on a critical path, may be damaged in the event of an accident. Moreover, in case of accident involving a pedestrian, these elements, which are dense, may hurt the pedestrian. FIG. 2 is a three-dimensional representation of an AGS device in which the one-piece P_ACT actuator is placed centrally between two series of flaps P_SHT1 and P_SHT2. The SD arrow indicates the direction of a shock of a motor vehicle (not shown) equipped with the AGS device, with an obstacle. This direction reflects the direction of the speed vector of the obstacle in the reference system of the AGS device of the motor vehicle at the time of the impact of the obstacle on the motor vehicle. The dimension along an axis X of the actuator P_ACT is represented by the reference XD. FIG. 3 is a three-dimensional representation of a variant of the AGS device of FIG. 2, in which the P_ACT actuator is placed laterally on the support frame of the AGS device. As in the AGS device of FIG. 2, the actuator P_ACT is located very in front of the module of front face of the vehicle, and is not protected. It is likely to be damaged and cause injury. The invention relates to an AGS device for controlling the air intake of a front-end module for a motor vehicle. Figure 4 shows, in the form of a longitudinal section, an embodiment of the invention. The AGS air intake control device of a front module for a motor vehicle comprises a set of shutters (also called "shutters") able to close the air intake. It includes for example a first set of shutters SHT1, and a second set of shutters SHT2. According to one possible implementation, all the shutters of the first series SHT1 are connected to each other, for example by means of a connecting rod, so that they are all moved simultaneously. According to one possible implementation, all the shutters of the second SHT2 series are connected to each other, so that they are all moved simultaneously. According to one possible implementation, all the shutters of the first SHT1 and the second SHT2 series are connected to each other, so that they are all moved simultaneously (the flaps of the two sets of flaps are moved simultaneously). The AGS device comprises an actuator ACT, for example electrical, arranged to control the flaps. ACT actuator comprises for example a servomotor, or a set of servomotors. The ACT actuator can be connected to a computer, which receives information from various sensors (engine temperature sensor, outdoor temperature sensor, vehicle speed sensor, etc.) and according to the collected information orders the closing or opening the flaps via the servomotor (s). The AGS device may also include a plurality of ACT actuators. Alternatively, the actuator ACT may comprise sub-elements each acting as an autonomous actuator. According to the embodiment illustrated in Figure 4, the front-end module further comprises a BUB beam bumper placed in a horizontal plane of the motor vehicle and perpendicular to a longitudinal axis of the vehicle. The ACT actuator of the AGS device is attached here to a support BOL (English bolster) of a radiator RAD. The ACT actuator is thus outside the critical path, and is unlikely to be damaged and cause injury as it is protected by the RAD radiator BOL holder and the RAD radiator itself. even. The remote actuator ACT drives a first series of shutters SHT1 (corresponding to the high channel of the AGS device) and a second series of shutters SHT2 (corresponding to the low channel of the AGS device). The AGS device comprises a flexible link connecting the ACT electric actuator to the shutters. The fact that the link is a flexible link instead of a link based on the integration of the actuator ACT in the immediate vicinity of the flaps (for example via a lever coming out of the actuator and directly controlling the flaps) makes it possible to deport ACT actuator. This avoids, during a collision of the motor vehicle with an entity (such as a PED pedestrian, or an OBS obstacle such as a pole), that the actuator ACT damages (directly or indirectly) the obstacle OBS or the pedestrian PED, and vice versa. This can even prevent contact between the ACT actuator and the OBS entity, PED colliding with the vehicle. This reduces the risk of serious pedestrian injury to PED or damage to the ACT actuator by the OBS obstacle (or even its destruction). According to the embodiment illustrated in FIG. 4, the flexible connection of the air intake control device AGS comprises a cable STR, for example of the piano wire type. It can also include several cables, each driving a separate set of flaps. According to another embodiment, the flexible connection of the air intake control device AGS comprises one (or more) rod (s) ROD. According to some implementations, the actuator comprises several servomotors, each of which can be connected to a portion of the flaps via a flexible connection of its own. It is possible to prefer a STR cable for some shutters and a ROD rod for others, in particular depending on the size of the front panel module. Another embodiment relates to a front-end module for a motor vehicle, comprising a protection element. By "protection" is meant that the element in question is not affected by a light collision involving the motor vehicle such as a collision of the parking type. The protective element may include elements of a nature to absorb mechanical shocks. The protective element can also have a significant mechanical strength, for example greater than that of a conventional body or that of the shutters of an AGS (which are typically made of fairly fragile plastic). A conventional body can be easily depressed or crumpled during a mechanical shock, thus damping such a shock. The protection element may have a mechanical strength comparable to that of the actuator itself. According to one possible implementation, the protection element is more resistant to mechanical shocks than is the actuator. The protection element may in particular be a structural element of the front-face module, or an element fixed in the module, or the structure, of the front face. The front panel module further comprises an air intake control device AGS according to one of the preceding embodiments with the ACT actuator of the air inlet control device being fixed to the air intake element. protection. The protection element is located between the ACT electric actuator and any possible shock point. Thus, in case of shock even quite violent with an obstacle OBS, the protective element isolates the actuator ACT from the obstacle OBS, which could otherwise damage it. In the case of an impact with a PED pedestrian, the PED pedestrian is no longer at risk of being injured by the ACT actuator. When the protective element is sufficiently recessed relative to the front of the vehicle, the impact of an obstacle against the vehicle can be cushioned by elements that are more fragile than the protective element or at least located upstream of the vehicle. the critical path. It is thus understood that ACT actuator is either moved away from the shock zone, or placed behind a rigid protective element so that it is more likely to be damaged or cause injury. According to an embodiment not illustrated, the protection element is a bumper beam BUB (also called "bumper beam" by reference to the English terminology). Such BUB bumper beam has a high mechanical strength and better withstand shocks with an obstacle OBS. The actuator ACT being fixed, in this embodiment, on the bumper beam BUB, it is thus protected from shocks. Another embodiment relates to a front-end module for a motor vehicle according to the preceding embodiment, in which, the bumper beam BUB is placed in a horizontal plane of the motor vehicle, perpendicular to a longitudinal axis of the vehicle, with a first series of shutters SHT1 located above the bumper beam BUB and a second series of shutters SHT2 located below the bumper beam BUB. The first set of flaps is thus a high way and the second series SHT2 is a low path. The lane is often larger than the high lane. But in some implementations an inverse configuration can be chosen, and in other implementations the two paths are of identical or similar sizes (their forms may nevertheless be different). The size refers to the area of the air intake defined by the affected shutters. ACT actuator, for example electric, is arranged to independently drive the two sets of shutters SHT1, SHT2. Thus, one way can be devoted for example to the cooling of a turbo radiator (in the case of a motor vehicle with a turbocharged engine), while the other can be devoted for example to the cooling of a radiator oil. It is possible to provide more than two lanes. Each channel can be controlled according to its own parameters (for example: turbocharger temperature, oil cooler temperature, etc.) and possibly common parameters (vehicle speed for example). Another embodiment relates to a front-end module for a motor vehicle according to the embodiment illustrated in FIG. 4. The front panel module includes a radiator BOL holder, and a RAD radiator supported by said radiator BOL holder. This radiator BOL support constitutes a protection element. An obstacle colliding with the vehicle should pass through at least the radiator RAD and its support BOL before it can damage the electric actuator ACT, which is fixed to this BOL support. Another embodiment illustrated in FIG. 5 relates to a front-end module for a motor vehicle, comprising a radiator as well as a fan system (commonly called fan system of English). Said fan system comprises a shroud SH RD, corresponding to a support element, carrying one or more propellers or fans (not shown), fixed behind the radiator RAD in order to channel the air that has passed through. the radiator RAD to the engine compartment. The term "behind" means downstream from the airflow, or in other words, that the RAD radiator is between the SHRD cap and the SHT1, SHT2 shutter series of the AGS device. The presence of the SHRD cap prevents that the air sucked by fans can include air other than that which has passed through the radiator RAD. The purpose of the fans is essentially to cool the RAD radiator. The actuator ACT is fixed inside, or on the SHRD cap, the SHRD cap can thus correspond to the protection element. The operation of an electric actuator is generally guaranteed in a temperature range of -40 ° C to 85 ° C, and can therefore operate within the cap. Other locations are possible for ACT actuator. It is sufficient that the location chosen to fix the actuator ACT respects the operating temperature range of the actuator ACT, that it keeps the actuator ACT safe thanks to a protection element, and that it ensures sufficient accessibility to the shutters of the AGS air intake device, via one or more rods, one or more cable (s) or any other flexible link (s) adapted ( s). Of course, the actuator ACT may comprise sub-elements, each of which may constitute, if necessary, autonomous actuators. These different actuators ACT can then be fixed each at different locations. It should be understood, however, that these exemplary embodiments are given by way of illustration of the object of the invention. The invention is not limited to these embodiments described above and provided solely by way of example. It encompasses various modifications, alternative forms and other variants that may be considered by those skilled in the art within the scope of the present invention and in particular any combination of the various embodiments described above.
