The specific structure and operation of the shock absorbing device S1 will be described in detail below.

As shown in fig. 1, the elastic member 40 includes: and a guide member 42, at least two elastic members 41 are arranged in the frame mounting member 10 and positioned between the frame mounting member 10 and the guide member 42, the guide member 42 is movably arranged in the frame mounting member 10, and the ejector 30 is in abutting fit with the guide member 42. Specifically, the guide member 42 only moves linearly in the left-right direction in the frame mounting member 10, when the vehicle travels on a bumpy road, the wheel mounting member 20 is forced to act on the ejector member 30, the ejector member 30 is forced to drive the guide member 42 to move leftward while compressing the elastic member 41, when the elastic member 41 is compressed, the pressure of the guide member 42 on the elastic member can be buffered, so that the shock absorbing effect is achieved, when the vehicle travels on a flat road, the ejector member 30 moves rightward under the elastic force of the elastic member 41, that is, the ejector member 30 returns to the original position, and at this time, the shock absorbing device S1 does not operate.

When the elastic member 41 is set to be two, two levels of shock absorption can be realized by combining the two elastic members 41, so that the shock absorption effect is more obvious, and certainly, when the vehicle needs to frequently run on a road with poor road conditions, more than two elastic members 41 can be further arranged, so that the shock absorption effect is better.

In detail, as shown in fig. 1, the at least two elastic members 41 include: a first elastic member 411 and a second elastic member 412, the length of the first elastic member 411 is greater than the length of the second elastic member 412, and the length of the elastic member 41 refers to the length of the elastic member 41 in the left-right direction, wherein one end of the first elastic member 411 and one end of the second elastic member 412 are connected or abutted with the frame mounting member 10, that is, the left end of the elastic member 41 is connected or abutted with the left end of the frame mounting member 10, the other end of the first elastic member 411 is connected or abutted with the guide member 42, and the guide member 42 is abutted with the other end of the second elastic member 412 after compressing the first elastic member 411 by a predetermined length.

The predetermined length of the first elastic member 411 is a length that is greater than that of the second elastic member 412, when the first elastic member 411 is compressed to a length that is the same as that of the second elastic member 412, the guide member 42 continues to compress the first elastic member 411 and the second elastic member 412, and since the second elastic member 412 is in the initial state of being compressed at this time, the amount of expansion and contraction is maximum at this time, energy generated by the movement of the ejector 30 can be continuously absorbed, secondary shock absorption can be realized, and the stability of shock absorption is greatly improved.

In more detail, as shown in fig. 1, the guide 42 includes: the guide head 421 and the guide rod 422, and the ejector 30 abuts against the middle part of the guide head 421 to stably push the guide head 421 to move in the left-right direction.
