Description

Technical Field

[0001] This utility model relates to a hydraulic shock absorber for bicycle seats, belonging to the field of shock absorber technology. Background Technology

[0002] Most bicycles do not have a shock absorber between the seat and the frame; the seat is directly connected and fixed to the seatpost via the seatpost clamp. A small number of bicycles do use a saddle spring shock absorber.

[0003] A bicycle seat hydraulic shock absorber provides hydraulic shock absorption between the saddle and the frame. It is another shock absorber connecting the saddle and frame, in addition to the front and rear wheel shock absorbers. It provides hydraulic shock absorption for both the saddle and the rider.

[0004] Chinese patent publication (publication number: CN 205706982 U) discloses a bicycle seat with spring shock absorbers. The seat includes a base with its front bottom connected to a curved manganese steel plate rod, and its rear bottom connected to the rod via two shock absorbers. When the seat is depressed, the spring is actually compressed, and the corresponding swing arm rotates. When the bicycle is released, the frame rebounds under the spring force. The shock absorbers dampen this rebound, stabilizing the frame after the rebound and significantly reducing the vibration caused by the spring. The bicycle seat features a simple structure and good shock absorption.

[0005] When installing existing car seat cushions, they are simultaneously fixed to the surface of the support rod with bolts. This makes it inconvenient for workers to disassemble the car seat cushions, requiring the use of special tools and affecting the disassembly results.

[0006] Therefore, a hydraulic shock absorber for bicycle seats is proposed. Utility Model Content

The surface of the movable rod 201 is movably connected to the interior of the support rod 1. The top of the shock-absorbing spring 202 is fixedly connected to the bottom of the movable rod 201, and the bottom of the shock-absorbing spring 202 is fixedly connected to the interior of the support rod 1. The top of the damping rod 203 is movably connected to the interior of the support rod 1. The buffer spring 204 is sleeved on the surface of the damping rod 203, and the bottom of the buffer spring 204 is fixedly connected to the interior of the support rod 1. The top of the buffer spring 204 is fixedly connected to the bottom of the damping rod 203. Two shock-absorbing springs 202 are provided, and the outer sides of the two shock-absorbing springs 202 are respectively fixedly connected to the surfaces of the movable rod 201 and the damping rod 203.

[0030] When the car seat cushion 3 moves up and down via the shock absorption mechanism 2, the movable rod 201 compresses the shock absorption spring 202, and during the compression process, the buffer spring 204 is also compressed, so as to absorb the impact force generated when falling and improve the comfort of the car seat cushion 3. By setting the shock absorption spring 202, when absorbing the impact force, the damping rod 203 and the movable rod 201 are compressed at the same time, thereby improving the shock absorption effect.

[0031] Example 2

[0032] like Figure 4-5 As shown, in one embodiment, a car seat cushion 3 is movably connected to the top of the movable rod 201, a positioning block 4 is fixedly connected to the surface of the movable rod 201, a cavity 5 is formed inside the positioning block 4, a movable rod 6 is movably connected inside the cavity 5, the left side of the movable rod 6 extends into the cavity 5, the right side of the movable rod 6 extends into the right side of the cavity 5, a connecting rod 7 is fixedly connected to the left side of the movable rod 6, a tension spring 8 is sleeved on the surface of the connecting rod 7, the left side of the tension spring 8 is fixedly connected to the cavity 5, the right side of the tension spring 8 is fixedly connected to the left side of the connecting rod 7, the left side of the connecting rod 7 is inside the car seat cushion 3, a connecting plate 9 is fixedly connected to the right side of the movable rod 6, the left side of the connecting plate 9 contacts the right side of the car seat cushion 3, an insertion groove 10 is formed on the surface of the car seat cushion 3, and the left side of the connecting rod 7 is movably connected to the inside of the insertion groove 10.
