Abstract

The invention discloses a cage-shaped skeleton structure of a vehicle body. The cage-shaped skeleton structure of the vehicle body comprises: a side wall assembly, and the side wall assembly includes an A-pillar assembly, a top edge beam assembly, a B-pillar assembly, a C Pillar assembly, door sill assembly, rear wheel house support beam assembly, the A-pillar assembly, the top side beam assembly, the C-pillar assembly, the door sill assembly and the rear wheel The hood support beam assembly is spliced ​​into an overall frame by aluminum profiles that are hollow inside and provided with reinforcing ribs in the cavity. The B-pillar assembly includes the B-pillar inner panel, the B-pillar outer panel, the B-pillar inner panel and the The outer panels of the B-pillar are all made of steel plates and connected by spot welding. The top and bottom of the B-pillar assembly are detachably connected to the top edge beam assembly and the threshold beam assembly respectively. The cage-shaped frame structure of the vehicle body according to the embodiment of the present invention has light weight, good overall rigidity performance, and excellent collision safety performance.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a cage-shaped skeleton structure of a vehicle body. Background technique [0002] With the development of the automobile industry, the weight of the car body directly affects the consumption of the car. However, at present, the car body frame is mainly composed of thin steel plates after welding, which has a large weight, a large number of parts, and a complex structure. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, an object of the present invention is to provide a cage-shaped frame structure for a vehicle body, which has good overall rigidity performance, excellent collision safety performance, and light weight. [0004] The cage frame structure of the vehicle body according to the embodiment of the present invention includes: a side wall assembly, the side wall assembly in...
