Definitions
- Front panel of a motor vehicle comprising a bumper beam
- the invention relates to a front face of a motor vehicle comprising a bumper beam.
- a vehicle front panel is a structural element capable of integrating various vehicle equipment such as headlights, flashing lights, horn, heat exchanger, motor-fan unit or complete cooling module, etc.
- the front panel thus provided with its equipment, constitutes a unitary module prepared and delivered by the supplier to be mounted on the vehicle by the manufacturer.
- the unitary module is mounted on lateral structural elements of the vehicle, such as the side members, the wings, then the front shield or the bumper is attached to the module, for example.
- heat exchangers are arranged between the front face and the bumper beam.
- these heat exchangers are located a few centimeters behind the bumper beam for reasons of efficiency, noise and so that they are not damaged in the event of a front impact.
- This technique has a major drawback of space.
- these heat exchangers are mostly made up of flat bundles with a large surface area. So they cannot be easily placed elsewhere.
- the object of the invention is in particular to overcome the aforementioned drawbacks.
- the invention relates to a front face of a motor vehicle comprising a bumper beam and at least one heat exchanger.
- said heat exchanger is located under the bumper beam in a substantially vertical orientation.
- the heat exchanger comprises, in a horizontal plane, an upper face of a shape similar to the shape of the bumper beam so that the upper face is covered by the bumper beam. shock.
- the upper face of the heat exchanger comprises a rectilinear central region of determined length and two regions of curved ends each having a tangent at their end making an acute angle with the rectilinear central region in the horizontal plane.
- said acute angle is between 0 'and 45 ".
- the determined length of the rectilinear central region is greater than one third of the lateral distance between the ends of the upper face.
- the upper face of the heat exchanger has a developed length greater than the height of the heat exchanger.
- the heat exchanger is set back relative to the bumper beam.
- the front face comprises a lower beam suitable for protecting a pedestrian in the event of a front impact with the latter.
- the heat exchanger has a developed length b greater than the spacing of the lower side members of the vehicle.
- the front face of a motor vehicle comprises a central zone situated above the bumper beam and free of any element capable of opposing resistance during a front impact.
- the front face comprises two horizontal crosspieces (24) situated respectively to the left and to the right of the median zone, above the bumper beam, and linked together by a deformable link (23 ).
- the deformable link (23) is a cable.
- the deformable link (23) is a beam.
- the middle zone includes elements capable of absorbing energy in the event of a front impact.
- FIG. 1 is a perspective view of a front face according to the invention.
- FIG. 2 is a partial top view of the front face according to the invention.
- FIG. 3 is a perspective view of a heat exchanger intended to be associated with a front face according to the invention.
- - Figure 4 is a perspective view of a front face according to an alternative embodiment of the invention.
- FIG. 1 The front face of a motor vehicle shown in this figure comprises an upper cross member 1, the ends of which are bent and intended to be fixed to upper side members (not shown) of the vehicle.
- Two vertical uprights 8 leave from the cross-member 1.
- Spacers 9 are connected to the cross-member 1 and to the uprights 8 to delimit housings 10 intended to receive the vehicle's headlights.
- the vertical uprights 8 are intended to be fixed to the lower side members 2 of the vehicle.
- the front face comprises a bumper beam 3 fixed on the lower beams 2.
- the bumper beam 3 is fixed to the beams 2 by screwing.
- the front face also includes a lower beam 7, called a pedestrian beam, intended to protect a pedestrian in the event of a front impact with the latter.
- This beam can be fixed to the lower beams 2. In another possible embodiment, this lower beam can be fixed to the bumper beam 3.
- a plate 14 surrounding a fan wheel 15 of a motor-fan unit is associated with the front face.
- a heat exchanger 5 is oriented substantially vertically under the bumper beam 3.
- the bumper beam 3 comprises fixing lugs and fasteners for shock absorbing pads (not shown ) in order to fix the heat exchanger 5.
- the heat exchanger 5 rests on the lower beam 7.
- the lower beam 7 comprises also fixing lugs and fasteners for shock absorbing pads.
- the bumper beam 3 is, in the example, a profile having a substantially en-shaped section.
- the bumper beam thus comprises a vertical core 17 and two horizontal wings 16 upper and lower facing each other.
- This profile is advantageously metallic and it has a curved shape adapted to the shape of the bumper (not shown) which is intended to be fixed later on the bumper beam.
- the heat exchanger 5 comprises an upper face of a shape similar to the shape of the bumper beam 3 in the horizontal plane XY so that the upper face is covered by the bumper beam.
- the upper face comprises a rectilinear central region 11 and two end regions 12, 13 curved towards the rear of the vehicle.
- the rectilinear central region 11 is of length L2, such that L2> 1/3 L1.
- the tangent at the end of the end region forms an acute angle ⁇ with the rectilinear central part 11 in the horizontal plane XY.
- the acute angle ⁇ is between 0 and 45 °.
- the heat exchanger 5, placed in the vertical extension of the bumper beam 3, is set back relative to the core of the bumper beam 3.
- the upper face of the heat exchanger 5 has a surface smaller than the surface of the lower wing 16 of the bumper beam.
- the heat exchanger 5, set back relative to the core 17 of the bumper beam 3, is placed under the lower wing 16 of the bumper beam.
- the heat exchanger 5 is shown separately in FIG. 3.
- the heat exchanger 5 (for example a vehicle engine cooling radiator) is advantageously divided into three parts arranged vertically and comprising a straight central part 18 and two end parts 19 and 20 curved towards the rear of the vehicle.
- the rectilinear central part 18 comprises the rectilinear central region 11 as an upper surface.
- the end portions 19 and 20 respectively comprise the end regions 12 and 13 as the upper surface.
- the developed length b of the upper face of the heat exchanger is greater than twice the height a of this exchanger.
- the geometry of the exchanger as described makes it possible to obtain a large exchange surface and to increase the efficiency of the exchanger.
- the positioning of this curved exchanger is particularly advantageous in terms of saving space.
- this exchanger 5 is intended to absorb the impact energy thanks to the surface of the deformable barrier represented by the surface of the heat exchanger 5 and the surface of the bumper shock.
- the position of the exchanger 5 makes it possible to clear a median zone, situated higher than the bumper beam and immediately behind the hood of the vehicle, of any rigid component capable of opposing resistance during a front impact and thus allowing in particular better shock absorption with pedestrians.
- Figure -4 shows another embodiment in which the cross member 1 of Figure 1 is replaced by two cross members 24 each forming the upper limit of a housing 10. Each cross member 24 is limited by the vertical upright 8 at one end. The two crosspieces 24 are interconnected by a link 23 which is easily deformable under the effect of a shock.
- the link 23 connecting the two crosspieces 24 is liable to collapse in the event of a violent impact on the bumper, while avoiding separation of the upper side members.
- the link is a cable.
- the link is a beam.
- the area higher than the bumper beam and between the two crosspieces is free of any rigid element, such as engine cooling component or hood closing element.
- This free area can be used to house components that may be deformed or displaced during a front impact, for example tanks, an air filter.
- the invention is not limited to the only embodiments described and illustrated.
- the heat exchanger 5 located below the bumper beam 3 could advantageously be replaced by several heat exchangers placed side by side.
