Abstract

The invention relates to an automobile body, in particular to a C pillar bottom connector structure of the automobile body. The C pillar bottom connector structure comprises a middle rear support plate, a front plate spring support, a middle partition of a rear crossbar, the rear crossbar and a middle rear support plate strengthening plate, wherein the rear crossbar is provided with an inner cavity, the middle partition of the rear crossbar is arranged in the inner cavity, the middle rear support plate strengthening plate is connected with a lateral side of the rear crossbar, the front plate spring support is connected with a lateral side of the rear crossbar, and the middle rear support plate is connected with the front plate spring support. The C pillar bottom connector structure has the advantages that torsional strength is strengthened, and fractures are eliminated effectively.

Description

technical field [0001] The invention relates to an automobile body, in particular to a C-pillar lower joint structure in the automobile body. Background technique [0002] The C-pillars flank the rear headrests. Generally, there are four types of pillars in the body of a minivan, which are A-pillar, B-pillar, C-pillar, and D-pillar from front to back. In addition to the support function, the column also plays the role of the door frame. [0003] At present, the structure of the existing lower joint structure of the C-pillar is relatively simple, and there are problems of insufficient torsional rigidity and easy cracking. Contents of the invention [0004] In order to solve the problems in the prior art, the present invention provides a C-pillar lower joint structure with sufficient torsional rigidity and not easy to crack. [0005] The present invention provides a C-pillar lower joint structure, which includes a central rear brace, a leaf spring front support, a middle ...
