Title:
VEHICLE CONTOUR FRAME MANUFACTURING METHOD, FRAME STRUCTURE AND VEHICLE SHELL
Document Type and Number:
WIPO Patent Application WO/2020/052033
Kind Code:
A1
Abstract:
Disclosed are a manufacturing method for a vehicle contour frame, a frame structure and a vehicle shell. First support beams (1) and second support beams (2) provided with notches are constructed first, and the first support beams (1) and the second support beams (2) are then inserted by means of the corresponding notches to form a cross fixing structure; and cross points of the first support beams (1) and the second support beams (2) are then welded to form an integrated structure. According to the manufacturing method for a vehicle contour frame, a notch structure is provided at the cross point where the support beams cross each other, so that the two beams are correspondingly inserted into one another, thereby ensuring the integrity of the support beams in two directions. The design of the notch size needs to ensure that the outer edges of all the support beams are aligned, in a fitting manner, with the notches after insertion so as to form a desired steel structure contour, thereby providing a frame support for a subsequent exterior panel. By means of the notch structure, the number of assembling beams can be substantially reduced, and the support beams can be assembled quickly and accurately, so that the support beams can form a desired external shape, and this is especially suitable for the streamlined contour of a vehicle body.
