Description

Title of the invention: Support for a grille of an electric motor vehicle. Technical field to which the invention relates

[0001] The present invention relates to the field of the automotive industry and, more particularly, to a support for a grille of an electric motor vehicle. Technological background

[0002] As is known, the term grille refers to the front part of a motor vehicle, generally located between its headlights. For motor vehicles equipped with an internal combustion engine, the grille also plays an essential role in cooling the thermal engine, by allowing a flow of air from outside the motor vehicle to enter the engine compartment. For this purpose, several passages are provided through the grille, generally in the form of grids, forming decorative patterns.

[0003] However, with the advent of electric motor vehicles, the need to ventilate the engine compartment has evolved. Electric motors generate less heat than internal combustion engines. Consequently, it is no longer necessary to ventilate the elements behind the grille of an electric motor vehicle as much. This evolution has led to a gradual reduction and then a disappearance of the air intakes fitted in the grilles fitted to electric motor vehicles.

[0004] Nowadays, the grilles of electric vehicles incorporate lighting devices such as emblems or central projectors. To achieve this, it was necessary to reinforce the mechanical rigidity of the grilles by increasing their thickness. As a result, the grilles can now weigh several kilograms and require the use of a specific support to ensure their retention on the motor vehicle.

[0005] However, during a head-on collision with a pedestrian, the grille is likely to strike the upper part of the pedestrian's leg. The mass of the grille and its support constitute a rigid zone likely to cause significant bodily injury to the lower limbs of a pedestrian.

[0006] The invention aims to reduce this risk of injury, by proposing a grille support allowing better absorption of a shock, generated during a collision with a pedestrian. Subject of the invention

[0007] To do this, the invention proposes a support for the grille of an electric motor vehicle comprising on at least one of its large faces, at least one groove. allowing deformation of the support or even rupture of the support, along said groove, when the support undergoes an impact on one of its large faces.

[0008] Thus, advantageously, the groove(s) allow the support to deform and / or break, so as to allow easier movement of the support towards the rear of an electric motor vehicle equipped with said support, when a pedestrian hits a grille of the motor vehicle held by the support according to the invention. As a result, the impact of the pedestrian impact is better absorbed by the grille fixed to the support according to the invention, which makes it possible to reduce the risk of serious injury to the pedestrian.

[0009] According to another embodiment of the invention, at least one groove is formed by constriction of the support. The groove(s) are configured to allow at least partial deformation and / or at least partial rupture of the support, when the support is struck by a pedestrian.

[0010] According to another embodiment of the invention, at least one groove is visible on a first large face of the support, intended to be oriented towards the interior of an electric motor vehicle. This embodiment allows for easier deformation or breakage of the support, so as to better absorb the shock of a pedestrian hitting said support.

[0011] According to another embodiment of the invention, at least one groove extends along one side of the support. Preferably, at least one groove extends over more than 80% of one side of the support. This embodiment promotes easier breakage or deformation of the support.

[0012] According to another embodiment of the invention, at least one groove extends along a first side of the support, and the first side is intended to be parallel or substantially parallel to the roadway when the support is mounted on an electric motor vehicle.

[0013] According to another embodiment of the invention, at least one groove extends along a first side of the support, and the first side is intended to be perpendicular or substantially perpendicular to the roadway when the support is mounted on an electric motor vehicle.

[0014] According to another embodiment of the invention, a grille is attached to a second large face of the support.

[0015] According to another embodiment of the invention, the grille comprises a luminous device, in the form of an emblem or a projector.

[0016] According to another embodiment of the invention, the support is formed from polypropylene.

[0017] According to another embodiment of the invention, the support has a thickness of between 2 mm and 3 mm.

[0018] According to another embodiment of the invention, at least one groove with a depth between 0.7 mm and 1.3 mm.

[0019] Of course, the various features, variants and embodiments mentioned above can be combined with each other in various combinations, provided that they are not incompatible or mutually exclusive.

[0020] The invention also relates to a motor vehicle comprising a grille support as described above.

[0021] According to another embodiment of the invention, the support is present at the front part of said vehicle.

[0022] According to another embodiment of the invention, the support is present at the center of the front part of said vehicle. Description of figures

[0023] The invention will be better understood from the following description, which relates to preferred embodiments, given as non-limiting examples, and explained with reference to the appended schematic drawings, in which:

[0024] [Fig-1] illustrates a perspective view of a support for a grille of an electric motor vehicle;

[0025] [Fig.2] illustrates a perspective view of a partial section of the grille represented by [Fig.l]. Detailed description of the invention

[0026] As a reminder, the invention proposes a support for a grille of an electric motor vehicle, making it possible to reduce the risk of injury to a pedestrian struck by a grille.

[0027] [Fig. 1] illustrates a non-limiting embodiment of a support 2 according to the invention. The support 2 is delimited by a first large face 4 opposite a second large face 6.

[0028] The first large face 4 is intended to be oriented towards the interior of an electric motor vehicle.

[0029] The second large face 6 is intended to be opposite a grille of an electric motor vehicle.

[0030] Remarkably, the support 2 has several grooves 8 visible on its first large face 4 as illustrated by figures 1 and 2.

[0031] The grooves 8 allow the support 2 to move more easily towards the rear of an electric motor vehicle equipped with said support, when a pedestrian hits a grille of the motor vehicle held by the support according to the invention.

[0032] As a result, the impact of the pedestrian impact is better absorbed by the grille fixed to the support according to the invention, which reduces the risk of serious injury to the pedestrian.

[0033] Preferably, the support 2 is formed from polypropylene.

[0034] The support 2 has a thickness of between 2 mm and 3 mm.

[0035] At least one groove 8 has a depth of between 0.7 mm and 1.3 mm.
