Referring to fig. 1 to 4, the shock absorber upper bracket structure 10 specifically includes an outer bracket 100 and an inner bracket 200, which are sleeved from outside to inside, the outer bracket 100 is used for being mounted on a vehicle body, a first mounting hole 101 is formed in the outer bracket 100 in a penetrating manner, and the inner bracket 200 is connected in the first mounting hole 101 in a liftable manner. One end of the inner bracket 200 near the shock absorber 30 is protruded out of the first mounting hole 101, and for convenience of description, both end portions of the inner bracket 200 are named as a first end and a second end, respectively, wherein the first end is an end near the shock absorber 30, and the second end is an end far from the shock absorber 30. A first mounting cavity 201 is formed at a first end of the inner bracket 200, and the first mounting cavity 201 is used for mounting the buffer block 20.

When the shock absorber upper mount structure 10 is mounted to the vehicle body, the distance between the cushion block 20 and the shock absorber 30 is fixed accordingly. If the distance between the buffer block 20 and the front of the damper 30 needs to be adjusted, only the inner bracket 200 needs to be driven to move relative to the outer bracket 100, and since the buffer block 20 is mounted on the inner bracket 200 and the position of the outer bracket 100 is fixed, the position of the buffer block 20 relative to the damper 30 changes when the inner bracket 200 moves relative to the outer bracket 100. Compared with the prior art that a plurality of buffer blocks with different specifications need to be prepared, and the distance between the buffer block and the shock absorber is changed by replacing the buffer blocks with different specifications, the shock absorber upper support structure 10 provided by the embodiment of the disclosure is a split structure consisting of the inner support 200 and the outer support 100, the position of the buffer block 20 can be flexibly adjusted by moving the inner support 200, and the shock absorber upper support structure is flexible and simple to operate and low in cost.

By screwing the inner support 200, the inner support 200 can flexibly move linearly relative to the outer support 100, the threaded connection has a self-locking function, the inner support 200 and the outer support 100 cannot be separated accidentally, and the position stability of the buffer block 20 is high.

In some other embodiments, the inner support 200 and the outer support 100 may be slidably connected instead of being screwed. Specifically, a sliding groove is formed in the side wall of the outer bracket 100 along the direction parallel to the axial direction thereof, a sliding block is convexly arranged on the outer wall surface of the inner bracket 200 along the direction parallel to the axial direction thereof, and the sliding block is slidably connected in the sliding groove, so that the sliding connection between the inner bracket 200 and the outer bracket 100 is realized. It should be noted that the outer wall surface of the slider and the inner wall surface of the sliding slot need to be tightly attached so as to provide enough friction force between the slider and the sliding slot, and the friction force needs to be large enough to ensure that the inner support 200 can move relative to the outer support 100 only under the action of an external force applied manually.

Furthermore, the sliding block can be protruded out of the sliding groove, the locking part is arranged on the protruding part of the sliding block, the locking of the position of the sliding block in the sliding groove is achieved through the locking part, when the position of the inner support frame 200 needs to be adjusted, the locking part needs to be detached firstly, and then the sliding block needs to be moved so as to move the inner support frame 200.

In some other embodiments, the inner stent 200 and the outer stent 100 may also be connected by magnetic attraction. Specifically, a first magnetic attraction piece is arranged on the inner bracket 200, a plurality of second magnetic attraction pieces are arranged on the inner wall surface of the outer bracket 100 at intervals along a direction parallel to the axial direction of the outer bracket, and the purpose of moving the inner bracket 200 relative to the outer bracket 100 is achieved by selecting one second magnetic attraction piece to attract the first magnetic attraction piece.
