Vehicle rear side wall assembly, mounting method thereof and vehicle

Abstract

The invention provides a vehicle rear side wall assembly. The assembly comprises a C column, a rear safety belt retractor support, a rear wheel cover outer plate, a rear wheel cover reinforcing piece and a rear leaning hook fixing reinforcing piece assembly connected with the rear safety belt retractor support and the rear wheel cover reinforcing piece, wherein the rear leaning hook fixing reinforcer assembly comprises a first fixing reinforcer and a second fixing reinforcer, the first fixing reinforcer is arranged on the C column and the rear safety belt retractor support, and the second fixing reinforcer covers the first fixing reinforcer and is disposed on the rear seatbelt retractor support and the rear wheel cover reinforcing piece. According to the vehicle rear side wall assembly, the connecting strength of the key area is improved through the first fixing reinforcing piece, meanwhile, through the first fixing reinforcing piece with the guiding function, under the condition that the vehicle continues to use existing surrounding environment pieces, combined assembly and tailor welding of the rear side wall assembly and the floor assembly are achieved, and plate thickness of the newly-added part is absorbed through shaping of the cover plate, so the first fixing reinforcing part is completely matched with the surrounding environment, and meanwhile, the weight of the vehicle is not affected.

Description

technical field [0001] The present invention relates to the field of vehicle parts, more specifically, to a vehicle rear side wall assembly, an installation method thereof, and a vehicle including the rear side wall assembly. Background technique [0002] At present, with the rapid development of the vehicle industry, people's requirements for vehicles are getting higher and higher. The rear side wall of the vehicle plays a major role in the bending, torsion, and comfort of the vehicle. [0003] In the rear side wall assembly of the existing vehicle, the rear safety belt retractor bracket and the rear wheel house reinforcement are connected by the rear hook fixing reinforcement, but due to the floor differences of various vehicles, etc., the existing rear The hook-fixed reinforcement is not strong enough to meet the torsion requirements of the fixedly connected seat belt retractor bracket and the rear wheelhouse reinforcement. Therefore, without changing the design of othe...
