[0036] The assembly process in this embodiment includes the following steps:

[0037] 1. Weld three front support vertical beams 16 at equal intervals to the upper end face of the chassis, and weld a front top beam 17 together horizontally at the upper end of the three support vertical beams; weld front load-bearing brackets 15 together in the vertical direction inside the three front support vertical beams 16, and weld four front load-bearing brackets 15 at equal intervals on the front support vertical beams 16 to form the front support frame.

[0038] 2. Weld a rear support vertical beam 19 to the opposite side. Columns 3 are symmetrically arranged on both sides of the rear support vertical beam 19. The bottom end of the column 3 is fixedly welded to the chassis. A rear top beam 18 is horizontally fixedly welded to the top of the rear support vertical beam 19. The two sides of the rear top beam 18 are fixed to the sides of the two columns 3 to form a rear support frame.

[0039] 3. In this embodiment, four limiting baffles 2 are provided. The four limiting baffles 2 are welded at equal distances between the front support frame and the rear support frame. One end of the limiting baffle 2 is welded to the outside of a front support vertical beam 16, and the other end is welded to the outside of the column 3 on the same side.

[0040] 4. Spot weld the motor mounting plate 5 to the two columns 3; and reinforce the weld seam.

[0041] 5. Spot weld the component mounting plate 4 to the two columns 3, with the component mounting plate 4 located above the motor mounting plate 5;

[0042] 6. Install the shock absorber wheel 6 and the rear wheel assembly 8 to the bottom of the chassis;

[0043] 7. Use a forklift or other transport tool to deliver the single-layer battery pack 1 into the frame, and use the front limiting baffle 2 to limit the side of the battery pack 1. The bottom of the battery pack 1 is supported by the support bracket. If multiple battery packs 1 are required, repeat the above operation.

[0044] 8. After the battery pack 1 is stably placed inside the frame, the side baffle 10 is fixed to the frame. In this embodiment, three side baffles 10 are provided. The side baffles 10 are vertically set between the upper part of the frame and the bottom plate. The upper end of the side baffle 10 is fixedly welded to the support beam 14, and the bottom end of the side baffle 10 is fixedly welded to the chassis to ensure the overall load-bearing strength of the frame.

[0045] 9. Use hoisting tools to hoist the charger 12, place the charger 12 in the charger placement area 11, and use fastening bolts to fix the charger 12 to the chassis;

[0046] 10. Install each component onto the component mounting plate 4. After installation, fix the component protective cover 9 on the component mounting plate 4.

[0047] 11. Secure the outer casing 13 to the chassis with fasteners through the corresponding fixing holes to ensure that the whole machine has dustproof and rainproof protection functions during outdoor operation.

[0048] By setting several front support brackets 15 on the front support frame and setting several rear support brackets 20 parallel to the front support brackets 15 on the rear support frame, several support bracket platforms are formed. This not only supports both ends of the battery pack 1, providing good load-bearing capacity, but also the hollow design of the front and rear support frames facilitates forklifts or other transport tools to transport the battery pack 1 into the frame for placement and fixation. It also facilitates the installation, disassembly and replacement of the battery pack 1, improving the safety factor of operation.

[0049] Example 2:

[0050] A limiting bracket 7 is fixedly welded to the side of the chassis. In this embodiment, the limiting bracket 7 has a Z-shaped structure, which can ensure that the bottom of the outer shell 13 can be subjected to vertical upward bearing force and front-to-back clamping force during the assembly process. This avoids the phenomenon of the outer shell 13 sagging and outward expansion due to its own weight and tension, which would cause the corresponding mounting holes to be mismatched.

[0051] Example 3:

[0052] The outer surfaces of the frame support beam, the limit baffle 2, the column 3, the component mounting plate 4, the motor mounting plate 5, and the bottom limit bracket 7 of the outer shell 13 are all coated with an anti-corrosion layer. In this embodiment, the anti-corrosion layer is made of epoxy resin, which ensures the anti-corrosion status of the whole machine components in the later operating environment.

[0053] In summary, Embodiments 2 and 3 in this specification mainly describe the differences from Embodiment 1. The same or similar parts between Embodiment 1 and other embodiments can be referred to each other.

[0054] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
