Embodiment Construction

[0018] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0019] The groove bottom of the supporting beam is provided with a vertical extension plate, and the vertical extending plate is welded on the vertical plate of the connecting beam, and the eversion edge of the supporting beam is welded on the horizontal plate of the connecting beam.

[0020] The horizontal plate is provided with an outward turning edge vertically outward, and the vertical plate of the connecting beam is provided with an outward step. The steps of the beams are matched with each other; the groove wall of the support beam is provided with an outer flange that is vertically folded outward, and the outer flange of the support beam is welded to the outer flange of the horizontal plate.

[0021] The specific embodiment of automobile body framework of the present invention, as Figure 1 to Figure 3 As shown, the body frame includes a total of...

Abstract

The invention relates to a car body frame and a design method thereof. The car body frame comprises the following six large frames: a roof frame, a left side wall frame, a right side wall frame, a front wall frame, a rear wall frame and a floor frame; each large frame comprises a supporting beam and connecting beams which are arranged at end parts of the supporting beam in a crossing manner; outward turned edges are arranged at the end parts of the supporting beam; the connecting beams are provided with matching surfaces used for being overlapped with the outward turned edges; the supporting beams in the large frames are overlapped with the connecting beams through a spot welding process; each connecting beam comprises an opening; and the openings of the connecting beams in every two adjacent large frames are opposite and form a closed structural part through the spot welding process. As the supporting beams and the connecting beams in the large frames are overlapped through the spot welding process, assembly welding of the large frames is realized and the precision of assembly welding is improved; and as the connecting beams in every two adjacent large frames form a closed structural part through the spot welding process, integrated assembly of the large frames is realized, such operation properties as intensity and rigidity can be met, positioning is accurate, and the precision of integrated assembly is high.

Description

technical field [0001] The invention relates to an automobile body frame and a design method thereof. Background technique [0002] The car body frame is an effective guarantee for providing space and safety for passengers. A large car body is composed of a frame and metal skin parts. The Chinese patent document with the announcement number CN203727485U and the announcement date of July 23, 2014 discloses a car body frame, including a large roof frame formed by welding rectangular tubes, a left side frame, a right side frame, and a front wall. There are six large pieces of skeletons including the frame, the rear wall frame and the floor frame, and then the large pieces of frames are welded and assembled to form the vehicle body frame. This traditional body frame adopts a steel structure design method, which has certain limitations on the development and manufacture of the automobile body frame. Arc welding is used when welding rectangular pipes, which has the problems of l...
