And a damping spring installation space is formed between the first support rods and the second support rods, and the damping spring is installed in the installation space.

In the embodiment, the damping spring 523 is sleeved on the guide post 522, one end of the guide post 522 is hinged with the supporting framework, the guide post 522 is provided with a limiting block 524 which is abutted against one end of the damping spring 523, the guide post 522 is sleeved with a push block 521, the damping spring 523 is positioned between the push block 521 and the limiting block 524, and the push block 521 can axially move along the guide post 522, so that the telescopic state of the damping spring 523 can be switched by changing the position of the push block 521 in the axial direction of the guide post 522; the push block 521 is hinged at a corner of the shock absorbing bracket 51 through a connecting rod, the push block 521 can rotate relative to the shock absorbing bracket 51 by taking the connecting rod as a fulcrum, and the expansion and contraction direction of the shock absorbing spring is consistent with the front and rear direction of the vehicle.

In fig. 3, arrow a indicates the rotation direction of the hinge point of the shock mount, arrow B indicates the compression direction of the shock spring, and arrow C indicates the movement direction of the shock mechanism. As shown in the figure, the vibration of the vehicle is represented by the up-down movement of the wheels relative to the supporting framework, when the wheels move upwards relative to the supporting framework, the shock absorbing bracket 51 is driven to rotate clockwise by taking the first end of the first supporting rod as a rotation center, as shown by an arrow a, meanwhile, as one end of the guide post 522 is connected with the supporting framework, the front-back position of the guide post 522 and the frame are relatively fixed, so that the shock absorbing bracket 51 rotates to drive the push block 521 connected with the guide post 522 to move along the guide post 522, and the push block 521 presses the shock absorbing spring 523 in the direction shown by an arrow B; thereby counteracting the vehicle shock through the shock absorbing spring 523. When the wheels move downwards relative to the supporting framework, the action process of the damping mechanism is the same.

The telescopic travel of the damping spring is limited by the height difference between the two hinge points of the damping bracket and the connecting point of the damping bracket and the pushing block, so that the installation position of the damping bracket is reasonably set, when the damping spring reaches the maximum compression state, a rod piece connected with a wheel shaft reaches the upward limit distance, but does not contact with the electronic components above the damping mechanism, and the electronic components above the damping mechanism are protected from damage; the lowest end of the shock absorbing support is prevented from colliding with the ground.
