Definitions

  • the invention relates to a motor vehicle, in particular a passenger car, with a front end and a cooling air inlet in an area of a so-called radiator grille.
  • a known motor vehicle has a front end with a radiator grille and a cooling air duct that extends behind the radiator grille in the longitudinal direction of the vehicle to guide cooling air to a so-called radiator.
  • the radiator is usually arranged between two engine longitudinal members, whereby it therefore has a corresponding maximum width, and extends over a large area - above and possibly also below the engine longitudinal members - of the front end in a vertical direction.
  • the width of the cooling air duct thus usually corresponds essentially to the width of the radiator behind it.
  • the radiator is arranged at a distance behind a bumper cross member.
  • walls of the cooling air duct extending in the longitudinal direction of the vehicle create undesirable resistance in the event of a collision with an obstacle.
  • a motor vehicle has a front end which has a cooling air inlet, which can be part of a cooling grille or can be formed by the radiator grille, and a cooling air duct, which extends in particular behind the cooling air inlet and adjoins it and which extends in particular from the cooling air inlet to the rear in the longitudinal direction of the vehicle.
  • the cooling air duct extends from a left Headlight or left headlight housing to a right headlight or right headlight housing in the transverse direction of the vehicle (a y-direction in the vehicle coordinate system).
  • the motor vehicle is preferably a passenger vehicle.
  • the cooling air duct between the headlights has a maximum width and the side outer walls (i.e. left and right outer walls in the transverse direction of the vehicle) of the cooling air duct do not form an obstacle in the event of a collision between the motor vehicle and an object or a road user such as a pedestrian if an outer skin is deformed in the longitudinal direction of the vehicle.
  • the cooling air duct does not have any additional walls within the outer walls either.
  • the left and right headlights or the left and right headlight housings can each form a side wall (a side outer wall) of the cooling air duct.
  • the cooling air duct can also have a wall that runs immediately adjacent to the left and right headlights or the left and right headlight housings.
  • the cooling air duct preferably has a width of 850 mm to 1200 mm, preferably 900 mm to 1150 mm, for example approximately 1000 mm.
  • the cooling air duct has a projection in a transverse direction, i.e. in a y-direction, from an inner side of the respective support in an outward direction of up to 140 mm, in particular 70 mm to 140 mm, for example approximately 70 mm or approximately 80 mm or approximately 90 mm or approximately 100 mm or approximately 110 mm or approximately 120 mm or approximately 130 mm, relative to a left front body longitudinal member or engine support.
  • the cooling air duct has a very large width in the y-direction of the vehicle coordinate system, so that lateral outer walls of the cooling air duct do not form an obstacle or form a smaller obstacle in the event of a collision of the motor vehicle with an object or a road user such as a pedestrian, if an outer skin (in the area of the cooling air inlet) is deformed in a central area of the front end in the longitudinal direction of the vehicle. This applies regardless of whether the lateral outer wall of the cooling air duct is deformed by a Headlights or a headlight housing or by a separate wall.
  • Lateral outer walls of the cooling air duct extend essentially in a y-direction and a z-direction of the vehicle coordinate system.
  • a distance between inner sides of the body longitudinal members can be approximately 700 mm to 900 mm.
  • a body longitudinal member can have a width of approximately 65 mm.
  • the cooling air duct extends in the vertical direction of the vehicle, i.e. in the z-direction in the vehicle coordinate system, at least up to an upper edge of the headlights or the headlight housings and/or up to an upper inner surface of an outer skin, in each case preferably over an entire width of the cooling air duct.
  • an upper wall of the cooling air duct is positioned as high up as possible so that there is as much free space as possible up to the upper wall of the cooling air duct. This free space therefore creates as little blocking potential as possible in the event of a collision with an object or a road user.
  • the cooling air duct can extend downwards at least to an upper edge of a bumper cross member.
  • the bumper cross member is preferably attached to the front ends of the engine longitudinal members or the front body longitudinal members, preferably with a crash box in between.
  • the cooling air duct can also extend to an area under the bumper cross member.
  • the cooling air duct is preferably produced by plastic injection molding. If necessary, the cooling air duct is formed in one piece, but can also consist of several interconnected parts. In particular, the cooling air duct can be composed of at least an upper part (an upper wall part), a left part (a left wall part) and a right part (a right wall part). As explained above, partial areas or partial walls of the cooling air duct can also be formed by a headlight or a headlight housing. The adjacent components of the cooling air duct then preferably lie sealingly against the headlight or headlight housing.
  • the cooling air duct has at least a length, ie an extension in the longitudinal direction of the vehicle, ie in the x-direction in the vehicle coordinate system, of 50 mm to 150 mm, preferably 60 mm to 150 mm, for example approximately 75 mm.
  • the cooling air duct extends in the direction of vehicle travel to an inner side of a body shell and/or to an inner side (rear side) of additional lights which are arranged in the central region of the front end.
  • the cooling air duct is wider than the distance between inner sides of a left front body longitudinal member or engine support and a right front body longitudinal member or engine support, in particular wider than the distance between outer sides of the left front body longitudinal member or engine support and the right front body longitudinal member or engine support.
  • the cooling air duct is relatively wide and a relatively large space can be provided without the potential for blockage in the event of a collision with an object or road user in the middle area of the front end of the vehicle.
  • the cooling air duct has a wall at a distance from the outer skin of the bodywork, which extends in the transverse direction of the vehicle, i.e. the y-direction, and in the vertical direction of the vehicle, i.e. the z-direction.
  • An opening for the intake of raw air is formed in the wall.
  • a raw air intake duct is connected to the opening.
  • the raw air intake duct serves, for example, as a raw air intake for an internal combustion engine.
  • the raw air intake is sufficiently spaced from the outer skin of the body so that, together with a corresponding raw air intake duct, there is no potential for blockage in the event of a collision with an object or road user.
  • the cooling air duct has elastically deformable regions at its front end for contact with an inner side of the body shell and/or with an additional light. The elastically deformable regions are attached to the walls of the cooling air duct extending in the longitudinal direction of the vehicle.
  • the elastically deformable areas could be molded in when the cooling air duct is manufactured.
  • the elastically deformable areas can thus rest against the vehicle's outer skin on the inside and compensate for manufacturing tolerances.
  • the cooling air duct can thus be designed to be sufficiently sealed against the vehicle's outer skin on the inside.
  • Fig. 1 is a schematic front view of an automotive vehicle showing an outline of a cooling air duct according to an embodiment of the present invention.
  • Fig. 2 is a schematic perspective view of a lateral region of the cooling air duct according to the embodiment of the present invention with a raw air intake.
  • a passenger vehicle has a front end 1 with a cooling air inlet in the form of a radiator grille, which is not shown in Figure 1, and a cooling air duct 3, which is arranged behind the radiator grille adjacent to a vehicle outer skin, also not shown, and whose outer outline is shown in Figure 1.
  • the cooling air duct 3 is arranged between a left headlight housing 5 and a right headlight housing 6 and extends in the vehicle transverse direction, ie in the y-direction in the vehicle coordinate system) from the left headlight housing 5 to the right headlight housing 6.
  • the cooling air duct 3 is arranged at least above a bumper cross member 7, which is arranged at the front ends of a left engine mount 9 and a right engine mount 10.
  • the cooling air duct 3 extends behind the bumper cross member 7 corresponding to a radiator 13.
  • the engine mounts 9, 10 can also be referred to as front body longitudinal members and are part of a body of the passenger vehicle.
  • the cooling air duct 3 guides the air from the radiator grille, i.e. the air inlet, to the radiator 13 arranged behind the cooling air duct 3.
  • the cooling air duct 3 has an upper wall 33 which extends substantially in the vehicle longitudinal direction (x direction) and the vehicle transverse direction (y direction) approximately at a height of an upper edge of the headlight housings 5 and 6 and close to an upper vehicle outer skin or a front flap 17. Furthermore, the cooling air duct 3 has side walls 31 (left) and 32 (right) which extend substantially in the vehicle longitudinal direction (x direction) and the vehicle vertical direction (z direction). In other words, the walls 31, 32, 33 form a boundary of the cooling air duct 3 in the vehicle transverse direction and in the vehicle vertical direction.
  • the side walls 31, 32 are spaced apart from one another by approximately 850 mm to 1200 mm.
  • the side walls 31 and 32 are spaced significantly further apart from each other than the two engine supports 9 and 10, i.e. the side walls 31 and 32 are located outside the engine supports 9, 10 in the transverse direction of the vehicle (y-direction).
  • the side walls 31 and 32 can alternatively also have corresponding recesses for the headlights 5 and 6, i.e. their headlight housings, in the area of the headlights 5 and 6, so that the headlight housings 5 and 6 form walls of the cooling air duct 3.
  • the side walls 31 and 32 lie as tightly as possible against the headlight housings.
  • Fig. 2 shows a right, front section of the front end 1 according to the embodiment in a perspective view.
  • sealing lips 37, 39 are attached to the front ends of the walls 31, 32, 33, which are designed for sealing contact with an inner side of a body shell.
  • the sealing lips 37, 39 are made of an elastic material, for example EPDM.
  • the cooling air duct 3 is made in several parts by means of plastic injection molding.
  • the cooling air duct 3 is manufactured by means of a two-component injection molding process, wherein the sealing lips 37, 39 are injection molded onto the walls 31, 33 and 34.
  • the cooling air duct 3 has a length of approximately 50 mm to 150 mm in the longitudinal direction of the vehicle (x-direction), i.e. from the radiator grille to the radiator 13.
  • the cooling air duct 3 has an end wall 35 approximately in the longitudinal direction of the vehicle at the level of the radiator 13 but in the transverse direction of the vehicle to the side of the radiator 13, which extends in the transverse direction of the vehicle (y-direction) and in the vertical direction of the vehicle (z-direction) and closes a gap or area between the radiator 13 and the side walls 31 and 32.
  • the cooling air duct 3 is therefore significantly wider than the radiator 13, as can also be seen from Fig. 1.
  • the end wall 35 lies sealingly against the radiator 13.
  • the end wall 35 there is an opening 15 for a raw air intake for a vehicle air conditioning system and/or an internal combustion engine.
  • the raw air is guided from the opening 15 via a raw air duct to the raw air consumer, for example an internal combustion engine.
  • the opening 15 for the raw air intake is formed in the end wall 35 to the right of the cooler 13.
  • the opening 15 can also alternatively or additionally be formed to the left of the cooler 13 in the corresponding end wall 35.
  • the outer body shell with the radiator grille is deformed in the longitudinal direction of the vehicle, i.e. dented.
  • the cooling air duct 3 which forms a free space, i.e. a free deformation space, behind the vehicle outer shell or the radiator grille up to the radiator 13 and extends from the left headlight housing 5 to the right headlight housing 6.
  • the cooling air duct 3 advantageously does not form any additional resistance in the aforementioned frontal collision, so that the requirements of the load case “upper leg impact” can easily be met without additional measures.
