The cab structure for an electric engineering vehicle includes: a cab frame assembly, a roof welded to the top of the cab frame assembly, a front bumper welded to the bottom front side of the cab frame assembly, a front bulkhead welded above the front bumper, a windshield mounting area reserved in the area between the roof and the front bulkhead on the cab frame assembly, a headlight mounting hole reserved at the front end of the front bulkhead, fenders welded to the bottom of both the left and right sides of the cab frame assembly, a pedal hole provided at the front end of the fender, a wheel arch provided in the middle of the fender, and a rear bulkhead welded to the rear end of the cab frame assembly.

[0003] The cab is an important component of the body of trucks and special-purpose vehicles, and is where professional drivers work day and night. Its structure is directly related to the driver's safety, work efficiency and health. The cab generally adopts a thin metal shell structure and is flexibly connected to the frame. It does not bear load and belongs to the non-load-bearing body. However, the cab itself needs to have a certain strength to cope with possible impacts from external objects. Therefore, this paper aims to propose a cab-body assembly with high self-strength. Utility Model Content

[0018] The technical solution of this application will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1-4 As shown, a cab assembly includes a roof 1 with an inverted U-shaped cross-section. The free ends of the two ear plate sections of the roof 1 are respectively connected to side baffles 2. The free ends of the ear plate sections of the roof 1 are provided with a first inner flange 3. The upper end of the side baffles 2 is provided with a second inner flange 4. The first inner flange 3 and the second inner flange 4 are welded together. A first frame body 5 is integrally provided in the rear of the roof 1. The length direction of the first frame body 5 is set along the inner surface of the roof 1. A second frame body 6 is integrally provided in the rear of the side baffles 2. A connecting plate 7 is provided between the first frame body 5 and the second frame body 6. The four corners of the connecting plate 7 are recessed, so that the connecting plate 7 forms a first groove 701 in the horizontal direction to avoid the first inner flange 3 and the second inner flange 4, and a second groove 702 in the vertical direction to fit the first frame body 5 and the second frame body 6. The front ends of the two side baffles 2 are connected as one piece by a bumper 8.

[0020] Specifically, the first frame 5 includes a main frame segment 501 with a U-shaped cross-section. The free ends of both ear plates of the main frame segment 501 are integrally provided with outwardly flanged sections 502, which are welded to the interior of the roof 1. The cross-sectional structure of the second frame 6 is consistent with that of the first frame 5. The first frame 5 and the second frame 6 adopt a hollow structure, which ensures support for the roof 1 and the side panels 2 while maintaining overall lightweight design.

[0021] Specifically, the front end of the side panel 2 is provided with a stepped surface 9, the bumper 8 is U-shaped, and the inner surface of the ear plate section of the bumper 8 is welded to the stepped surface 9. The stepped surface 9 ensures the flatness and aesthetics of the connection between the bumper 8 and the side panel 2.

[0022] Specifically, several U-shaped ribs 10 are spaced along the length of the inner surface of the ceiling 1. The free ends of the U-shaped ribs 10 extend to the upper surface of the first inner flange 3. An L-shaped plate 11 is welded to the inner wall of the side baffle 2. The horizontal section of the L-shaped plate 11 is welded to the inner wall of the side baffle 2. A folded plate 12 is welded to the outer surface of the U-shaped ribs 10, and the other end of the folded plate 12 is welded to the vertical section of the L-shaped plate 11. The U-shaped ribs 10 improve the strength of the ceiling 1 itself. Simultaneously, the L-shaped plate 11 and the folded plate 12 form a fixed connection between the side baffle 2 and the ceiling 1 through a secondary connection, further enhancing the overall strength.

[0023] Specifically, a hook 13 is provided inside the canopy 1 for easy connection, and the hook 13 protrudes from the rear of the canopy 1. The hook 13 facilitates the lifting of the entire assembly during the welding process and its transfer on the production line.

[0024] This cab adopts an integral welded structure, which integrates the roof 1, side panels 2, bumper 8, first frame 5, second frame 6 and connecting plate 7 into a single weld. This results in high overall strength, low processing difficulty and cost savings. Furthermore, the first frame 5, second frame 6 and connecting plate 7 are fully covered inside the cab, greatly improving the overall strength of the cab and enhancing its impact resistance.

[0025] This utility model is not limited to the above embodiments. Based on the technical solutions disclosed in this utility model, those skilled in the art can make some substitutions and modifications to some of the technical features without creative labor, and these substitutions and modifications are all within the protection scope of this utility model.
