Description

Support unit for fender and vehicle body assembly with support unit Technical Field The invention relates to the field of vehicle bodies, in particular to a support unit for a fender and a vehicle body assembly with the support unit. Background The automobile fender is used as an important component part of the automobile body panel and is positioned above the wheels, and mainly plays roles in protecting the automobile body, reducing air resistance and beautifying the appearance of the automobile body. At present, most of automobile fenders on the market are formed by stamping thin steel plates or aluminum alloy plates, and the automobile fenders can meet the light-weight design requirement, but have the problem of poor dent resistance. In order to improve or solve the above technical problems, an auxiliary device is required to increase the dent resistance of the fender. Disclosure of Invention The invention aims to provide a support unit for a fender, which can increase the anti-dent capability of the fender. In order to achieve the above purpose, the technical scheme adopted by the invention is as follows: A support unit for a fender comprises a primary support unit and a secondary support unit; The primary support unit comprises a support bracket; The secondary support unit comprises at least one energy absorption block arranged on the support bracket. The support bracket comprises a bracket body, wherein the bracket body comprises bracket end plates, lateral support plates are arranged on two opposite sides of the support end plates, one end, far away from the bracket end plates, of each lateral support plate is provided with a joint plate, and the vertical section of the support bracket is in a shape like a Chinese character 'ji'. The lap joint connecting plate comprises a middle connecting plate, two lateral connecting plates are respectively arranged at two opposite ends of the middle connecting plate, the middle connecting plate and the lateral connecting plates are distributed in a staggered mode, the lateral connecting plates are connected with the bridging connecting plates and the middle connecting plate, and the lateral connecting plates and the bridging connecting plates enclose an assembly sinking groove.
