Therefore, they cannot be understood as limitations on the present invention.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0037] Example 1

[0038] See Figure 1 and Figure 2 This embodiment provides a shock absorbing device comprising: a shock absorber 1, a side panel 2 hingedly connected to one end of the shock absorber 1, and a connecting panel 3 hingedly connected to the side panel 2. One of the side panel 2 and the connecting panel 3 is provided with a boss 21, and the other is provided with a rotation hole 31 adapted to fit the boss 21. The boss 21 is rotatably mounted within the rotation hole 31, thereby hingedly connecting the side panel 2 and the connecting panel 3. Two sets of side panels 2, connecting panels 3, and the hinged structure therebetween are provided, one on each opposite side of the shock absorber 1.

[0039] Specifically, the connecting plate 3 is an elongated plate-like structure having a first connecting plate end 32 and a second connecting plate end 33. The side panel 2 is a triangular-shaped structure having a first side panel end 22, a second side panel end 23, and a third side panel end 24. The first connecting plate end 32 is disposed away from the side panel 2, the second connecting plate end 33 is disposed near the first side panel end 22, and both the second side panel end 23 and the third side panel end 24 are disposed away from the connecting plate 3. The second side panel end 23 is located obliquely above the third side panel end 24, and the second side panel end 23 is disposed away from the connecting plate 3 compared to the third side panel end 24. The shock absorber 1 is an elongated structure having a first shock absorber end 11 and a second shock absorber end 12. The first shock absorber end 11 is disposed near the first connecting plate end 32, and the second shock absorber end 12 is disposed near the second side panel end 23.

[0040] According to the basic structure and basic orientation of the shock absorber 1, the side plate 2 and the connecting plate 3, the second end 12 of the shock absorber is hingedly connected to the second end 23 of the side plate, and the second end 33 of the connecting plate is hingedly connected to the first end 22 of the side plate.

[0041] The shock absorber 1 is hingedly connected to the side panel 2 via the hinge rod 7. That is, the second end 12 of the shock absorber and the second end 23 of the side panel are both hingedly connected via the hinge rod 7.

[0042] The hinged connection between the connecting plate's second end 33 and the side plate's first end 22 is achieved by the boss 21 being rotatably mounted within the rotation hole 31. This embodiment uses the boss 21 provided at the side plate's first end 22 and the rotation hole 31 provided at the connecting plate's second end 33 as an example. The boss 21 is located on the side of the side plate's first end 22 and protrudes toward the connecting plate's second end 33, allowing it to be rotatably mounted within the rotation hole 31. This arrangement ensures that the boss 21 and rotation hole 31 do not occupy the active space of the shock absorber 1.

[0043] That is, the shock absorbing device of this embodiment is provided with a boss 21 on one of the side panel 2 and the connecting panel 3, and a rotation hole 31 adapted to the boss 21 on the other, so that the hinged connection between the side panel 2 and the connecting panel 3 is realized by the boss 21 being rotatably mounted in the rotation hole 31. This not only ensures the stable hinge connection between the side panel 2 and the connecting panel 3, but also avoids the hinge structure of the side panel 2 and the connecting panel 3 appearing in the activity space of the shock absorber 1, thereby maintaining a larger activity space of the shock absorber 1 to ensure the shock absorbing effect of the shock absorber 1.

[0044] The above is the basic structure of the shock absorbing device. The specific structure of the shock absorbing device of this embodiment is described below:

[0045] Two side panels 2 are relatively parallel and located on both sides of the shock absorber 1 respectively. Two connecting plates 3 are relatively parallel and located on both sides of the shock absorber 1 respectively. The corresponding two side panels 2 and two connecting plates 3 are respectively installed in the corresponding rotating holes 31 through corresponding bosses 21 for hinged connection.

[0046] A hinged rod 7 extends through the first end 11 of the shock absorber to hingeably connect the two connecting plate first ends 32. A hinged rod 7 extends through the second end 12 of the shock absorber to hingeably connect the two side plate second ends 23. The distances between the shock absorber 1 and the two side plates 2, as well as the distances between the shock absorber 1 and the two connecting plates 3, are equal, ensuring a uniform and stable transmission of the shock absorption effect of the shock absorber 1.

[0047] Moreover, the hinges between the two sets of side panels 2 and the connecting plate 3 are achieved by rotatably mounting the bosses 21 on the side panels 2 on the rotating holes 31 on the connecting plate 3. The hinge structure between the side panels 2 and the connecting plate 3 does not occupy the movable space of the shock absorber 1 and has no effect on the shock absorbing activity of the shock absorber 1.

[0048] On this basis, the side plate 2 or the connecting plate 3 with the boss 21 is positioned closer to the shock absorber 1 than the side plate 2 with the rotation hole 31. That is, the side plate 2 is positioned closer to the shock absorber 1 than the connecting plate 3. The boss 21 is positioned on the outer side of the side plate's first end 22 and is rotatably mounted within the rotation hole 31 at the connecting plate's second end 33, further increasing the movable space of the shock absorber 1.

[0049] Furthermore, a lubrication ring 4 is provided around the radial outer periphery of the boss 21. The lubrication ring 4 is positioned within the rotation hole 31 and is in close contact with the inner wall of the rotation hole 31 and the radial outer wall of the boss 21. The lubrication ring 4 can be made of smooth plastic or metal and can rotate relative to the boss 21 and / or the rotation hole 31 to enhance the smooth rotation of the boss 21 within the rotation hole 31 and provide sensitive vibration reduction.

[0050] At the same time, the rotation hole 31 is a through hole, and the central axis of the boss 21 is provided with a threaded hole 211. The threaded hole 211 is threadedly connected to the threaded rod 5. The threaded rod 5 is arranged outside the rotation hole 31 and extends into the threaded hole 211. The through structure of the rotation hole 31 can increase the contact area between the boss 21 and the rotation hole 31, thereby improving the stability of the hinged connection.

[0051] On this basis, a threaded hole 211 is set on the boss 21 and is equipped with a threaded rod 5. The rod part of the threaded rod 5 is threadedly engaged with the threaded hole 211, and the outer end part of the threaded rod 5 radially protrudes outward to cover and exceed the rotating hole 31 to abut the connecting plate 3, which can further improve the hinge stability between the side plate 2 and the connecting plate 3 and prevent the boss 21 from detaching from the rotating hole 31.

[0052] Furthermore, a washer 6 is provided on the radial outer periphery of the threaded rod 5. The washer 6 is sandwiched between the outer end of the threaded rod 5 and one of the side plates 2 and the connecting plate 3, wherein the rotation hole 31 is provided. The washer 6 covers and extends beyond the rotation hole 31. In other words, the washer 6 sandwiched between the outer end of the threaded rod 5 and the connecting plate 3 not only improves the secure installation of the threaded rod 5 but also reduces the requirement for the radially outward projection of the outer end of the threaded rod 5, thereby increasing the selection range of threaded rods 5.

[0053] It should be noted that the threaded rod 5 can be a common screw structure in the prior art.

[0054] In addition, the threaded hole 211 passes through the boss 21 and one of the side plate 2 and the connecting plate 3 provided with the boss 21, and the threaded rod 5 passes through the threaded hole 211. In this way, the distance between the threaded rod 5 and the boss 21 is increased, which can effectively prevent the threaded rod 5 from loosening.

[0055] Furthermore, a retaining ring is provided radially protruding from the outer periphery of the end of the threaded rod 5 that passes through the threaded hole 211. The retaining ring abuts against one of the side panels 2 and the connecting plate 3 that has the boss 21. In other words, the retaining ring abuts against the inner side of the side panel 2. The retaining ring prevents the threaded rod 5 from shifting or even detaching from the threaded hole 211, thereby ensuring the stability of the hinged connection between the side panel 2 and the connecting plate 3.

[0056] Of course, the limiting ring here can be replaced by a nut, which has the same locking effect.

[0057] Example 2

[0058] See Figure 3 and Figure 4 This embodiment provides a unicycle, comprising: a wheel assembly 100, a frame assembly 200, and the shock absorber 300 of Embodiment 1. The frame assembly 200 is slidably mounted on the wheel assembly 100. One of the side plate 2 and the connecting plate 3 is hingedly connected to the wheel assembly 100, and the other is hingedly connected to the frame assembly 200. The other end of the shock absorber 1 is hingedly connected to the connecting rod 3, or the other end of the shock absorber 1 is hingedly connected to either the wheel assembly 100 or the frame assembly 200.

[0059] Specifically, the third end 24 of the side panel 2 is hingedly connected to the wheel assembly 100, the first end 32 of the connecting plate 3 is hingedly connected to the frame assembly 200 and the first end 11 of the shock absorber through the hinge rod 7, and the seat 400 is installed on the frame assembly 200.

[0060] In this way, the shock absorbing device 300 of the unicycle is provided with a boss 21 on one of the side panel 2 and the connecting panel 3, and the other is provided with a rotating hole 31 adapted to the boss 21, so that the hinged connection between the side panel 2 and the connecting panel 3 is realized by the boss 21 being rotatably installed in the rotating hole 31. This not only ensures the stable hinge connection between the side panel 2 and the connecting panel 3, but also avoids the hinge structure of the side panel 2 and the connecting panel 3 appearing in the activity space of the shock absorber 1, thereby maintaining a larger activity space of the shock absorber 1, and can give full play to the shock absorbing effect of the shock absorber, thereby ensuring the user's riding experience and riding safety.
