Detailed ways

In order to make the purpose, content and advantages of the utility model clearer, the specific implementation of the utility model will be further described in detail below.

A cab body-in-white structure proposed by the utility model is characterized in that it includes six assemblies of the front wall 1, the floor 4, the right wall 2, the left wall 6, the rear wall 5 and the top cover 3, and each assembly Both are composed of high-strength skeletons and outer skins of corresponding shapes, and the outer skins are made of medium-thick plates; a space structure is formed by welding between the high-strength skeletons and outer skins, as follows:

A cavity structure is designed between the high-strength skeleton of the front wall 1 and the outer skin, and the A-pillar 16, B-pillar 18, and C-pillar 19 of the side wall 6 serve as a high-strength skeleton, and a double cavity is designed between it and the outer skin structure, which has the function of energy absorption for collapse; the high-strength skeleton and outer skin of other assemblies are welded to form an overall structure, see Figure 1 and Figure 2.

The high-strength skeleton is composed of floor skeleton beams 9, front wall skeleton beams 7, side wall skeleton beams 8, 12, rear wall skeleton beams 11, and roof skeleton beams 10.

The floor skeleton beam 9 is welded by left and right side beams 13, 17, left and right middle longitudinal beams 1415 and a plurality of beams; The A-pillar, B-pillar, C-pillar and multiple beams are welded; the back frame beam 11 is composed of multiple beams and columns; the roof frame beam 10 is welded by multiple beams and longitudinal beams.

The main beams of the high-strength skeleton are the left and right beams 13 and 17 of the floor, and the left and right middle longitudinal beams 14 and 15 as the main frame beams of the ground. The vertical frame is composed of upright beams, the crossbeam 21 of the front wall, the crossbeam 22 and the longitudinal beam 2423 of the top cover constitute the main body of the body-in-white to form a closed frame structure, as shown in FIG. 3 .

The advantage of the overall frame structure is that one point of force and multiple force transmission paths can effectively disperse the load, greatly improving the rigidity of the body-in-white and vehicle safety performance.

Body-in-white frame beams: they are all welded by multiple sections of transverse frames 27 and multiple sections of vertical frames 28 through multiple joints at the joints. The joints are L-shaped joints 31, T-shaped joints 30 and cross joints 29. The frame 27, the vertical frame 28 and the connectors 29, 30, 31 are provided with flanges on both sides of the connection, and the lateral frame 27 or the vertical frame 28 is overlapped with the flanges of the connectors 29, 30, 31 and connected by soldering;

The skeleton structure welded by stamping sheet metal parts is adopted, and a variety of joints are used to meet the welding requirements of different positions. The stressed structure is more stable, and the overall rigidity and strength of the skeleton structure of the body-in-white are greatly improved. It solves the problems of open welding and cracking between beams of the existing cab body-in-white and improves the safety of the body-in-white.
