A rear wheel cover lap joint structure and automobile body-in-white

Abstract

The invention discloses a rear wheel casing lap-joint structure and an automobile body in white. The lap-joint structure is composed of a rear wheel casing inner plate, a rear wheel casing outer plate, a shock absorber support, a rear wheel casing stiffening plate and a wheel casing inner plate upper supporting plate. The upper part of the rear wheel casing stiffening plate and the upper part of the rear wheel casing inner plate are connected with the rear wheel casing outer plate; the lower part of the wheel casing inner plate upper supporting plate is connected with the rear wheel casing stiffening plate, the wheel casing inner plate upper supporting plate extends to pass the bending part of the rear wheel casing stiffening plate, the upper part of the wheel casing inner plate upper supporting plate is connected with the rear wheel casing outer plate, the middle part of the wheel casing inner plate upper supporting plate protrudes towards the direction away from the upper part of the rear wheel casing stiffening plate to form a cavity with the rear wheel casing stiffening plate and the rear wheel casing outer plate, and stiffening convex ribs are arranged on the front and back sides of the cavity; the rear wheel casing inner plate is a flat plate provided with stiffening ribs. The rear wheel casing lap-joint structure and the automobile body in white have the advantages that the structure is compact, a wheel casing inner plate upper supporting plate do not take up a space inside the automobile, interior trim plates and seats of the automobile are convenient to arrange, the in-automobile space utilization rate is high, the impact load in the vertical direction is favorably borne, the weight is favorably decreased, the lightweight goal is realized, and the fuel economy is improved.

Description

technical field [0001] The invention belongs to the technical field of an automobile body-in-white overlapping structure, and in particular relates to a rear wheel cover overlapping structure and an automobile body-in-white. Background technique [0002] The utility model patent "A Reinforcement Assembly for Rear Wheel Cover" (Application No. 2015203905763) and the invention patent "A Connecting Structure for Rear Wheel Cover and Automobile with It" (Application No. 2015102330640) provide related technical solutions to solve the problem of rear wheel The reliability of the cover structure under heavy loads and complex road surfaces, but the inner panel support plate is installed on the inner side of the wheel house inner panel, and the inner panel support plate occupies the space in the vehicle, which is not conducive to The layout of the chairs, the utilization rate of the space in the car is low. Simultaneously, the rear wheel house inner plate and outer plate in the prio...

[0002] The utility model patent "A Reinforcement Assembly for Rear Wheel Cover" (Application No. 2015203905763) and the invention patent "A Connecting Structure for Rear Wheel Cover and Automobile with It" (Application No. 2015102330640) provide related technical solutions to solve the problem of rear wheel The reliability of the cover structure under heavy loads and complex road surfaces, but the inner panel support plate is installed on the side of the inner panel of the wheel house, and the inner panel support plate occupies the space in the vehicle, which is not conducive to The layout of the chairs, the space utilization rate in the car is low

Simultaneously, the rear wheel house inner plate and outer plate in the prior art directly bear the load transmitted from the ground, so it is suitable to adopt thicker materials, and the rear wheel house inner plate and outer plate are often due to their large surface area, causing the rear wheel house The inner and outer panels are heavy, which is not conducive to the lightweight design of the vehicle, which hinders the realization of energy saving and emission reduction

In addition, the overlapping structure of the high-reliability rear wheel cover in the prior art cannot effectively distribute the load transmitted from the ground to other parts of the vehicle body reasonably, and there are defects in safety and reliability

[0003] Cracking of the inner plate of the wheel house and cracking of the solder joints of the reinforcement plate is a major problem that China FAW Co., Ltd. has encountered during the R020 model development process. The project node of the entire body development is delayed, so this technical problem needs to be solved urgently
