Description

Technical Field

[0001] The utility model relates to the technical field of vehicle safety, in particular to a front bumper support bracket with a vehicle safety collapse mechanism. Background Art

[0002] Existing front bumpers of cars are usually installed on the radiator beam or the front end frame. These parts are usually complex in structure and very strong, but have poor buffering performance and are difficult to absorb the energy generated by pedestrian collisions. When pedestrians and vehicles collide, the front bumper cannot effectively collapse and deform to buffer the damage, thereby reducing the damage to pedestrians. Utility Model Content

[0003] In view of the above problems, the purpose of the utility model is to provide a front bumper support bracket with a pedestrian protection collapse mechanism, which is used to absorb the energy generated during the collision by breaking the collapse structure on the support bracket during a pedestrian collision, thereby reducing the damage caused by the car to the pedestrian's legs or knee joints during a collision, thereby achieving the protection of pedestrians and overcoming the shortcomings of the above-mentioned prior art.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A front bumper support bracket with a collision avoidance mechanism comprises: a support collapsible bracket installed on a front anti-collision beam, a front bumper upper bracket installed on the support collapsible bracket, and a front bumper assembly installed on the front bumper upper bracket, wherein a front bumper energy absorption box is arranged near the front anti-collision beam of the front bumper assembly, and the support collapsible bracket is composed of a support plate, side edges arranged on both sides of the support plate, and a tensioning bar arranged on the support plate, wherein a plurality of collapse grooves are opened on the side edges, and a plurality of groups of collapse holes are opened transversely on the support plate corresponding to the positions of the collapse grooves.

[0006] As a preferred embodiment of the present invention, three collapse grooves are provided on each of the side edges.

[0007] As a preferred embodiment of the present invention, three groups of collapse holes are provided on the support plate.

[0008] As a preferred embodiment of the present invention, each group of collapse holes on the support plate is four.

[0009] The advantages and positive effects of the utility model are: the utility model can effectively absorb the energy generated by the front bumper pedestrian protection collision due to the front bumper shaping surface being too close to the front anti-collision beam by 71mm (conventionally about 100mm) through product collapse. And the simple structure also achieves the effect of optimizing the structure of the front frame, reducing weight and reducing costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1It is a schematic diagram of the overall structure of the utility model.

[0011] Figure 2 It is a schematic diagram of a supporting collapsible bracket in the utility model.

[0012] Figure numerals: supporting collapsible bracket 1, front anti-collision beam 2, front bumper upper bracket 3, front bumper assembly 4, front bumper energy absorption box 5, support plate 6, side 7, tensioning bar 8, collapse groove 9, collapse hole 10. DETAILED DESCRIPTION

[0013] See also Figure 1-2 The present embodiment provides a front bumper support bracket with a collision protection mechanism, comprising: a support collapsible bracket 1 installed on a front anti-collision beam 2, a front bumper upper bracket 3 installed on the support collapsible bracket 1, and a front bumper assembly 4 installed on the front bumper upper bracket 3, wherein the front bumper assembly 4 is provided with a front bumper energy absorption box 5 near the front anti-collision beam 2, the support collapsible bracket 1 is composed of a support plate 6, side edges 7 arranged on both sides of the support plate 6, and a tie bar 8 arranged on the support plate 6, three collision grooves 9 are opened on the side edges 7, and three groups of 12 collision holes 10 are opened horizontally on the support plate 6 corresponding to the positions of the collision grooves 9, and the support plate 6 adopts a wavy shape with an arc.

[0014] Working principle: A support collapsible bracket 1 is provided on the front anti-collision beam 2 to protect pedestrians from collision. After the front bumper of the vehicle collides with the pedestrian, the support collapsible bracket 1 begins to break from the collapse groove 9 and the collapse hole 10, thereby effectively absorbing the energy generated during the collision, reducing the damage to the pedestrian's leg or knee joint caused by the car during the collision, and achieving the protection effect on the pedestrian.

[0015] The above are only specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
