[0029] The shock-absorbing air bag 13 is arranged inside the inner shell 3, the upper part of the shock-absorbing air bag 13 is fixed to the upper end sleeve 7 through the upper air bag copper ring 14, the lower part of the shock-absorbing air bag 13 is fixed to the damping shell 11 through the upper air bag copper ring 14, the upper end sleeve 7 is provided with a vent hole 16, the spring 17 is sleeved on the outside of the damping cylinder 10, the top end of the spring 17 is against the inner top wall of the upper end sleeve 7, the bottom end of the spring 17 is against the upper part of the damping shell 11, and the oil seal rubber ring 17 is installed inside the lower end sleeve 8.

[0030] Furthermore, a universal joint 18 is provided at the top end of the damping rod 9 , and the top end of the universal joint 18 is arranged in a groove 19 , and the groove 19 is arranged at the bottom end of the upper end sleeve 7 .

[0031] Furthermore, a retaining ring 20 is provided on the outer portion of the upper end of the damping shell 11 , and the lower end of the spring 17 abuts against the retaining ring 20 .

[0032] Furthermore, an external thread is provided on the side wall of the upper end sleeve 7, and an internal thread matching the external thread is provided on the inner wall of the upper portion of the inner shell 3.

[0033] Furthermore, a damping chamber is provided inside the damping cylinder 10 , and the lower end sleeve 8 is threadedly connected to the inner bottom of the damping cylinder 10 .

[0034] Furthermore, the interior of the damping chamber is filled with an oil-gas mixture filler.

[0035] Furthermore, an annular groove is formed on the inner wall of the lower end sleeve 8, and an oil seal rubber ring is installed inside the annular groove.

[0036] Furthermore, the outer shell 2 and the damping shell 11 are both cylindrical, and the outer shell 2 and the damping shell 11 are both made of aluminum alloy.

[0037] The working principle of the utility model is:

[0038] The shock-absorbing airbag 13 is fastened to the upper end sleeve 7 and the damping shell 11 through the upper airbag copper ring 14 and the lower airbag copper ring 15. The upper joint 2 and the damping shell 11 are softly connected through the shock-absorbing airbag 13. At the same time, a spring 17 is arranged outside the damping cylinder 10. The spring 17 can slow down the shock-absorbing rebound. The inside of the damping cylinder 10 is filled with oil and gas mixture, and multiple layers of oil seals and gas seals are pre-set at the upper and lower ends to prevent gas or oil leakage.

[0039] At the same time, the center of the upper end sleeve 7 is provided with a thread, and the thread is used to connect the damping rod 9. The damping cylinder 10 is provided with a thread inside, and is used to connect the lower end sleeve 8. Thus, the entire shock absorption is directly formed into two separately fixed parts, the upper and lower parts. The mutual movement of the two parts can be directly regarded as the mutual movement of the damping rod 9 and the damping cylinder 10. The soft connection of the upper and lower parts of the shock absorber is fixed by the shock absorbing air bag 13 and the upper air bag copper ring 14 and the lower air bag copper ring 15. The upper air bag copper ring 14 bites the upper part of the shock absorbing air bag 13 to the outer wall of the upper end sleeve 7. The addition of the upper air bag copper ring 14 makes the soft shock absorbing air bag 13 and the outer wall of the upper end sleeve 7 with the groove 19 bite more tightly. The same structure is also applied to the lower air bag copper ring 15 and the damping shell 11. These two structures ensure the air tightness and ductility of the internal space of the shock absorption, and it will not leak easily. The material of the air bag can also adapt to the repeated compression of the internal air.

[0040] In order to prevent the damping rod 9 from touching the bottom of the cylinder when the cylinder stroke reaches the maximum, a gasket 12 is partially installed on the damping cylinder 10. The soft gasket can prevent the damping rod 9 from touching the bottom and damaging the internal structure when the shock absorber shrinks to the maximum; an oil seal rubber ring is installed on the inner wall of the damping cylinder 10 and the inner wall of the lower end sleeve 8 to ensure the air tightness of the cylinder to the maximum extent;

[0041] When the shock absorber is under pressure, the upper sleeve 7 and the lower sleeve 8 shrink inward, and the damping shaft 4 connected to the upper sleeve 7 moves downward. At the same time, due to the sealing of the damping cylinder 10, the existence of the shock-absorbing air bag 13 and the spring 17, this shrinkage is usually slow. When the external pressure disappears, the shock absorber rebounds from the middle to both ends, and due to the oil in the upper space of the damping rod, the rebound process is also slow.

[0042] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0043] Although the article uses more terms such as shock absorbing body 1, shell 2, upper connector 3, upper connecting plate 4, lower connector 5, lower connecting plate 6, upper end sleeve 7, lower end sleeve 8, damping rod 9, damping cylinder 10, damping shell 11, gasket 12, shock absorbing air bag 13, upper air bag copper ring 14, lower air bag copper ring 15, vent 16, spring 17, universal joint 18, groove 19, retaining ring 20, etc., it does not exclude the possibility of using other terms. The use of these terms is only for more convenient description and explanation of the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
