Embodiment Construction

[0015] The present invention will be further described below in conjunction with accompanying drawing:

[0016] Such as figure 1 , figure 2 The assembly structure of an aluminum alloy skeleton body shown includes a front frame 1, a rear frame 2, a side frame 3, a roof frame 4 and a bottom frame, a front frame 1, a rear frame 2, and a side frame 3 1. The roof frame 4 is made of aluminum alloy, the bottom frame is made of rectangular tubes, the positions where the front frame 1, the rear frame 2 and the side frame 3 are connected to the bottom frame sheet beams are riveted with transitional rectangular tubes, and the top frame 4 L-shaped aluminum alloy connecting plates are riveted at positions connected to the side frame 3 , the front frame 1 and the rear frame 2 .

[0017] Specifically, the transitional rectangular tube 5 is first riveted at the positions corresponding to the side frame 3, the front frame 1, the rear frame 2 and the section beam of the underframe, that is, ...

Abstract

The invention relates to an aluminium alloy framework automobile body assembling structure and an assembling method thereof. The aluminium alloy framework automobile body assembling structure comprises a front wall framework, a rear wall framework, a side wall framework, a top cover frame and an underframe, wherein the front wall framework, the rear wall framework, the side wall framework and the top cover frame are made of aluminium alloy, and the underframe is made of rectangular tubes. Transitional rectangular tubes are riveted at the positions where the front wall framework, the rear wall framework and the side wall framework are connected with an underframe piece beam, and L-shaped aluminium alloy connecting plates are riveted at the positions where the top cover frame is connected with the side wall framework, the front wall framework and the rear wall framework. Through the above technical scheme, the front wall framework, the rear wall framework, the side wall framework and the top cover frame are made of the aluminium alloy, the self weight of an automobile body is lowered, and meanwhile the two connecting modes of the L-shaped aluminium alloy connecting plates and the transitional rectangular tubes are used for guaranteeing the connecting transformation of all the parts.

Description

technical field [0001] The invention relates to an assembly structure of an aluminum alloy skeleton body and an assembly method thereof. Background technique [0002] At present, light weight, high speed, safety, energy saving, comfort, and long life are the symbols of the modernization of passenger cars, and the key to realizing the high speed of passenger cars is to solve the problem of light weight of passenger cars. Lightweight is very important to reduce the traction and braking force of passenger cars, reduce energy consumption, reduce tire wear, and improve the running speed of passenger cars. However, the existing bus bodies are generally welded with rectangular tubes, which are heavy in weight and low in strength, and cannot achieve lightweight passenger cars. Contents of the invention [0003] The object of the present invention is to provide an assembly structure of an aluminum alloy frame body, which reduces the weight of the body and has the effect of saving ...
