Problems solved by technology
[0002] The inner panel of the rear side wall of the existing minibus mostly adopts the integral molding method. In order to meet the installation requirements of the assembly parts in the rear side wall area, the sealing plate area of the rear side wall inner panel is mostly a large-plane characteristic structure. This large-plane feature causes the rear side The overall rigidity of the inner panel is insufficient, and it is easy to deform during transportation
[0003] The avoidance hole in the sealing plate area of the inner panel of the rear side wall adopts the form of direct opening, and the avoidance hole is directly opened. Due to the large diameter of the avoidance hole, stress concentration is easily generated around the avoidance hole, resulting in insufficient rigidity of the installation surface.

The invention relates to a rear side inner panel and a rear side assembly for automobile bodies and provides a rear side inner panel comprising a main plate. The main plate is provided with a seal plate overall-subsidence recess provided with local subsidence recesses. Each local subsidence recess is provided with a mounting hole. The seal plate overall-subsidence recess is provided with a clearance hole, and an opening of the clearance hole is provided with a bore turnup edge. The invention further provides the rear side assembly. The rear side inner panel and the rear side assembly have the advantages that the seal plate overall-subsidence recess fits the local subsidence recesses, overall rigidity of the rear side inner panel is improved, the rear side inner panel is prevented from deforming in the transport process, each local subsidence recess is provided with the mounting hole for fitting, and mounting face rigidity is improved; the large diameter clearance hole is arranged in the seal plate overall-subsidence recess, the opening of the clearance hole is provided with the bore turnup edge, stress concentration is effectively avoided, and rigidity of a mounting face of the clearance hole is improved.
Description
technical field [0001] The invention relates to a car body, in particular to a rear side wall inner panel and a rear side wall assembly in the car body. Background technique [0002] The inner panel of the rear side wall of the existing minibus mostly adopts the integral molding method. In order to meet the installation requirements of the assembly parts in the rear side wall area, the sealing plate area of the rear side wall inner panel is mostly a large-plane characteristic structure. This large-plane feature causes the rear side The overall rigidity of the inner panel is insufficient, and it is easy to deform during transportation. [0003] The avoidance hole in the sealing plate area of the inner panel of the rear side wall adopts the form of direct opening, and the avoidance hole is directly opened. Due to the large diameter of the avoidance hole, stress concentration is likely to occur around the avoidance hole, resulting in insufficient rigidity of the installatio...
