[0035] Please refer to Figure 5 and Figure 6The elastic connecting piece includes two connecting ends 18 and a middle connecting rod 19. The upper connecting end 18 is hinged to the top rear end of the inner side support 2, and the lower connecting end 18 is hinged to the end of the compensation swing arm 8. The opposite ends of the two connecting ends 18 are respectively provided with sliding cavities 20, and the sliding cavities 20 are provided with compression springs 21. The two ends of the middle connecting rod 19 respectively penetrate into the sliding cavities 20 and abut against the compression springs 21. The elastic connecting piece is internally provided with the compression springs 21. When the vehicle body encounters bumps, vibrations or uneven road surfaces during driving, the movement state of the wheel frame will change, and the compensation swing arm 8 will act accordingly. The compression springs 21 can effectively absorb and buffer the impact force in this process. Through compression and expansion, the spring converts the vibration energy into elastic potential energy, reduces the degree of vibration transmitted to the vehicle body, thereby protecting the battery module 1, materials and other components inside the vehicle body, reducing the risk of damage caused by vibration, and improving the stability and comfort of transportation. This structure enables the elastic connecting piece to adaptively adjust according to the relative movement of the wheel frame and the compensation swing arm 8. Whether the wheel frame is lifted up front or back, the elastic connecting piece can adapt to this change through its own deformation, maintain the stability of the connection, ensure the normal movement of the wheel frame and the balance of the vehicle body, and enhance the passing ability and adaptability of the vehicle body under complex road conditions.

The end of the anti-dropping block 22 is provided with a guide column extending into the sliding cavity 20, and the compression spring 21 is sleeved on the guide column. The end of the connecting end 18 where the sliding cavity 20 is located is threadedly installed with an end sleeve 26, and the inner diameter of the end sleeve 26 is smaller than the outer diameter of the anti-dropping block 22. The end sleeve 26 will block the anti-dropping block 22 to prevent the middle connecting rod 19 from coming out of the sliding cavity 20. The compression spring 21 is sleeved on the guide column to guide the compression direction of the compression spring 21. The spring can maintain straight-line movement during compression and expansion, avoiding deflection or twisting. This not only helps to improve the working efficiency of the spring and reduce energy loss, but also prolongs the service life of the spring. Because the spring will be subjected to excessive local stress and accelerate wear and fatigue if it is deflected during normal operation, the guide column effectively avoids these problems and ensures that the spring is always in the best working state, thereby improving the buffering and shock-absorbing performance of the elastic connecting piece.

[0037] Please refer to Figure 4The lower side of the middle part of the rear end face of the mounting groove is provided with a reinforcing plate 23, the middle part of the compensating swing arm 8 is provided with an upwardly extending connecting lug plate 24, and the connecting lug plate 24 is hinged to the reinforcing plate 23 through a pin shaft. The reinforcing plate 23 arranged at the lower side of the middle part of the rear end face of the mounting groove effectively enhances the structural strength of the rear part of the mounting groove. When the battery module 1 is placed in the mounting groove and the vehicle body is subjected to various external forces during operation, the reinforcing plate 23 can disperse and bear these forces, prevent deformation or damage of the rear part of the mounting groove, and thus ensure the installation stability and safety of the battery module 1. Meanwhile, the connecting lug plate 24 upwardly extending from the middle part of the compensating swing arm 8 is hinged to the reinforcing plate 23 through a pin shaft, so that the connection between the compensating swing arm 8 and the vehicle body is more firm, the rigidity of the overall structure is further improved, the connection between the wheel carrier and the vehicle body is still reliable under complex working conditions, and the ability of the vehicle body to cope with various road conditions is enhanced.

[0038] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
