The invention discloses a body-in-white rear assembly structure, which belongs to the technical field of body-in-white. The body-in-white rear assembly structure comprises: a rear floor assembly, including a rear floor longitudinal beam; a rear side wall assembly, fixed on The rear floor assembly; the rear side wall assembly includes a rear wheel house inner panel assembly, and the rear wheel house inner panel assembly includes a rear suspension fixing seat and a rear wheel house inner panel, and the rear suspension The fixing seat is fixed on the inner panel of the rear wheel house and extends to the bottom of the rear floor longitudinal beam and is fixedly connected with the rear floor longitudinal beam. The invention can provide stable and effective support for the upper suspension of the rear shock absorber, improve the durability strength of the rear assembly structure of the body-in-white, and simultaneously improve the torsional rigidity of the body-in-white.
Description
technical field [0001] The invention relates to the technical field of body-in-white, in particular to a rear assembly structure of a body-in-white. Background technique [0002] SUV (sport utility vehicle) has the advantages of strong power, good off-road performance, spaciousness and comfort, and good load and passenger functions, and is more and more popular in the market. [0003] Generally speaking, a large SUV model has three rows of seats, and the rear load of a large SUV model is very large. In the body-in-white rear assembly structure of SUV models, in order to improve the stability and smoothness of the chassis, the support position of the rear shock absorber is relatively high, and the upper suspension support point of the rear shock absorber is arranged on the rear wheel housing. [0004] In the body-in-white rear assembly structure of the above-mentioned SUV model, due to the thin rear wheel cover material and the distance between the upper suspension support p...
