Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of automobile parts and relates to a bumper, in particular to an anti-sinking front bumper upper support bracket structure which is beneficial to driving protection. Background Art
[0002] The matching of the front bumper and the hood (engine cover) of a car is an important matching area during the appearance review. The gap surface difference between the front bumper and the hood has a great impact on the exterior appearance. With the current aesthetic concept, the appearance of cars has become more and more complex. In addition, people now require electronic and automated functions, and more and more electronic parts are integrated into the front bumper, resulting in the weight of the front bumper becoming heavier accordingly. During use, it is affected by its own gravity, which may cause the front bumper to sink, causing the gap between the front bumper and the hood to increase, affecting the appearance. In order to prevent the front bumper from sinking, it is necessary to add a Z-direction support structure to the front bumper mounting bracket. However, the increase in the weight and structure of the bracket will also affect the pedestrian protection of the car. If the structural strength of the front bumper upper bracket is too strong, it will cause greater damage to the legs and knees of pedestrians when colliding with pedestrians, which is not conducive to the pedestrian protection of the front bumper. Therefore, it is necessary to design a front bumper upper support bracket structure that is beneficial to pedestrian protection and can play a supporting role. Utility Model Content
[0003] In view of the above-mentioned technical problems and shortcomings, the purpose of the utility model is to provide an anti-sinking front bumper upper support bracket structure which is beneficial to pedestrian protection. The bracket structure is provided with a support crush zone at the front end of the bracket body. The support crush zone is easily deformed when impacted in the X direction, and the front bumper can be supported along the Z direction, thereby optimizing the gap surface difference between the front bumper and the hood, and protecting pedestrians.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] The invention discloses an anti-sinking front bumper upper support bracket structure which is beneficial to driving protection, comprising a bracket body, the bracket body being fixed on a vehicle body, the bracket body being provided with a plurality of front bumper clamping points and front bumper mounting points, the improvement being that a support crushing zone is provided at the front end of the bracket body, the support crushing zone being arranged in the middle position of the bracket body, the support crushing zone being provided with two inner support crushing parts which are spaced apart and symmetrically arranged, and an outer support crushing part which is spaced apart from the inner support crushing parts by a certain distance and is arranged on the outer side of the inner support crushing parts, the inner support crushing parts and the outer support crushing parts being S-shaped components which are easily deformed when impacted in the X direction, the inner support crushing parts and the outer support crushing parts being arranged below a front bumper middle support bracket, being matched with a gap with the front bumper middle support bracket, and being used for supporting the front bumper middle support bracket and a front bumper upper skin fixed on the front bumper middle support bracket in the Z direction.
[0006] As a preferred embodiment of the present invention, a crush zone is further provided at the front end of the bracket body, and the crush zone is arranged on both sides of the bracket body. A crush part is provided in the crush zone, and the crush part is an S-shaped component that is easily deformed when impacted in the X direction. The crush parts on both sides of the bracket body are symmetrically arranged.
[0007] As a preferred embodiment of the utility model, the inner supporting collapse member includes a plurality of S-shaped vertical plates arranged side by side at equal intervals, the outer supporting collapse member includes a plurality of S-shaped vertical plates arranged side by side at equal intervals, the collapse member includes a plurality of S-shaped vertical plates arranged side by side at equal intervals, the ends of the S-shaped vertical plates arranged side by side at equal intervals are connected by connecting end plates, and the middle is connected or not connected by connecting middle plates.
[0008] As a preferred embodiment of the present invention, the inner support collapse member, the outer support collapse member, the collapse member and the bracket body are an integrated structure and are injection molded using PP-GF20.
[0009] Advantages and beneficial effects of the utility model:
[0010] (1) The support bracket structure provided by the utility model can effectively absorb the energy generated by pedestrian collision, thereby protecting the pedestrian's knees and reducing the damage to pedestrians caused by collision; at the same time, it can also play a role of Z-direction support for the bumper, preventing the front bumper from sinking due to its own weight, resulting in poor appearance matching, and achieving the dual functions of matching the gap of the front bumper cover and protecting pedestrians. It not only improves the quality control of the surface difference gap at the front bumper cover, but also can effectively absorb the energy generated by pedestrian collision without increasing the Z-direction structure of the energy absorption box structure, thereby achieving the effect of reducing weight and reducing costs.
[0011] (2) The supporting crushing member and the crushing member on the supporting bracket structure provided by the utility model are both S-shaped components that are easy to deform. The S-shaped component is composed of a plurality of S-shaped vertical plates arranged side by side at equal intervals. The ends of the S-shaped vertical plates arranged side by side at equal intervals are connected by connecting end plates. When a pedestrian collides with the front bumper along the X direction or there is a certain impact angle, the S-shaped component can absorb energy through its own deformation, and the energy absorption effect is good.
[0012] (3) The support bracket provided by the utility model has a simple structure and can be integrally formed by injection molding, which is convenient to process. BRIEF DESCRIPTION OF THE DRAWINGS
