[0023] Unless otherwise defined, all technical and scientific terms used in the specification are the same as those commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used in the specification includes any and all combinations of one or more related listed items.

[0024] Please refer to Figure 1 and Figure 2 The damping seat 100 provided by the embodiments of the present application comprises a seat pipe 10, a chuck 20, a limiting pin 30 and an elastic member 40. The seat pipe 10 is provided with a sliding groove 10s. One end 21 of the chuck 20 is used for cushion installation, and the other end 22 of the chuck 20 is inserted into the sliding groove 10s. The other end 22 of the chuck 20 can slide relative to the sliding groove 10s in the direction from the groove opening to the groove bottom of the sliding groove 10s. The limiting pin 30 is provided with two ends respectively arranged on both sides of the groove wall of the sliding groove 10s. The other end 22 of the chuck 20 is provided with a sliding hole 22s, and the limiting pin 30 is inserted into the sliding hole 22s. The sliding hole 22s can slide relative to the limiting pin 30 in the direction from the groove opening to the groove bottom of the sliding groove 10s. The elastic member 40 is accommodated in the sliding groove 10s, one end of the elastic member 40 is arranged at the groove bottom of the sliding groove 10s, and the other end of the elastic member 40 is arranged at the other end 22 of the chuck 20. Through the damping seat 100, when a user sits on the cushion, when subjected to vibration, the other end 22 of the chuck 20 slides relative to the sliding groove 10s, and the elastic member 40 is compressed or stretched, thereby playing a damping function and improving user experience.

[0025] In addition, since the elastic member 40 is arranged in the sliding groove 10s in the seat pipe 10, the depth of the sliding groove 10s can be reasonably arranged, thereby reasonably limiting the length of the elastic member 40. Compared with the case that the elastic member 40 is directly arranged in the seat pipe 10, the use length of the elastic member 40 can be shortened, not only saving the use of materials, but also reducing the risk of failure of the shortened elastic member 40.

[0026] It is worth mentioning that the elastic member 40 can be a spring, or the elastic member 40 can be an elastic pad.

[0027] It is worth mentioning that the sliding groove 10s is arranged below the chuck 20, and the elastic member 40 is arranged below the chuck 20, so that when a user acts on the cushion arranged on the chuck 20, the elastic member 40 can reduce the shock of the user on the cushion, thereby improving the user experience.

[0028] It is worth mentioning that in some embodiments, the damping seat 100 further comprises a bushing 50, the bushing 50 is arranged on the sliding groove 10s, and the bushing 50 surrounds the other end 22 of the chuck 20. Through the bushing 50, the bushing 50 is located between the groove wall of the sliding groove 10s and the other end 22 of the chuck 20, so that when the other end 22 of the chuck 20 slides relative to the sliding groove 10s, on the one hand, the friction between the other end 22 of the chuck 20 and the sliding groove 10s is reduced, facilitating the sliding of the other end 22 of the chuck 20 relative to the sliding groove 10s; on the other hand, through the arrangement of the bushing 50, when the other end 22 of the chuck 20 slides relative to the sliding groove 10s, the bushing 50 is worn, thereby avoiding the wear of the groove wall of the sliding groove 10s, and improving the durability of the seat pipe 10.

[0029] It is worth mentioning that in some embodiments, the seat pipe 10 comprises a pipe body 11 and a mounting portion 12, the mounting portion 12 is connected to the side surface of the pipe body 11, and the mounting portion 12 protrudes from the pipe body 11; the sliding groove 10s is arranged on the mounting portion 12. Through the arrangement of the mounting portion 12, the elastic member 40 is arranged on the mounting portion 12 instead of being directly arranged on the pipe body 11, so that the height direction of the mounting portion 12 can be reasonably set, the depth of the sliding groove 10s can be reasonably set, the length of the elastic member 40 can be reasonably limited, and compared with the case that the elastic member 40 is directly arranged in the pipe body 11 of the seat pipe 10 (the length of the pipe body 11 is generally longer), the use length of the elastic member 40 can be shortened, which not only saves the use of materials, but also reduces the risk of failure of the elastic member 40.

[0030] It is worth mentioning that in some embodiments, the cross-sectional area of the mounting portion 12 is greater than the cross-sectional area of the pipe body 11. Through this arrangement, the processing of the sliding groove 10s is facilitated, the arrangement of the elastic member 40 is facilitated, and the replacement of the bushing 50 is also facilitated after the bushing 50 is worn.
