[0026] Specifically, the buffer spring 7 is sleeved on the damping telescopic rod 6, when the load plate 5 is impacted by the weight of the goods or bumpy due to the vehicle driving, the buffer spring 7 can absorb and buffer part of the impact force, reduce the damage to the damping telescopic rod 6 and other components of the off-weight detection assembly, improve the durability and stability of the off-weight detection assembly, prolong its service life, and ensure the continuous and reliable operation of the off-weight detection function.

[0027] Referring to Figure 2 , the load plate 5 covers the inside of the vehicle compartment 4, and the outer wall of the load plate 5 is matched with the inner wall of the accommodating chamber.

[0028] Specifically, it can ensure that the goods are evenly placed on the load plate 5, so that the load plate 5 can accurately perceive the weight distribution of the goods, avoid inaccurate detection of the off-weight of the goods due to the gap between the load plate 5 and the inner wall of the vehicle compartment 4, and improve the accuracy and reliability of the off-weight detection, and provide more accurate data for vehicle balance control.

[0029] Referring to Figure 3 , the outer wall of the lower part of the damping telescopic rod 6 is provided with a rotating seat, and one end of the first supporting arm 8 is connected with the damping telescopic rod 6 through the rotating seat.

[0030] Specifically, the first supporting arm 8 is connected with the damping telescopic rod 6 through the rotating seat, so that the first supporting arm 8 can rotate flexibly around the damping telescopic rod 6, and when the load plate 5 is inclined, the first supporting arm 8 can respond in time and change the angle to realize the detection of the off-weight condition, ensure the flexibility and reliability of the structure of the off-weight detection assembly, and make the off-weight detection function more sensitive.
