Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, and particularly relates to a body gantry frame. Background Technique

[0002] When making a passenger car, several body gantry frames are used in cooperation with several longitudinal and transverse beams for welding and fixing, and finally the main frame of the passenger car can be made.

[0003] At present, when most of the body gantry frames of passenger cars are welded and assembled, there is a lack of limiting and docking structures on the outer surface of the main body of the gantry frame. As a result, when welding and fixing with several longitudinal and transverse beams, only lap welding can be carried out, and the welding points are not firm enough and are prone to breakage. Therefore, it is necessary to design a passenger car body gantry frame that can effectively limit and dock with the longitudinal and transverse beams and make the welding part more stable to solve the above problems. Content of the Utility Model

The installation components include an installation part, a support side plate installation slot, a second insertion rod, an installation block, and a second limiting insertion hole. The installation components are used to dock the frame main body with the support side plate. A limiting component is arranged at the top end of the frame main body; the limiting component includes a docking hole, a first insertion rod, a fixed insertion hole, a docking ring, a limiting slot, and a first limiting insertion hole. The limiting component is used to dock the frame main body with the roof cross beam.

[0006] As a further improvement of the utility model, the installation part is arranged at both ends of the frame main body and is designed in an arc structure. The installation part is integrally formed with the frame main body and its thickness is less than that of the frame main body.
