[0037] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0038] like Figs. 1 to 3 As shown, in some embodiments, a shock-absorbing device includes a load-bearing assembly 100, a first connecting assembly 200, a second connecting assembly 300, a shock absorber 400, and a support assembly 500. The first connecting assembly 200 has a first hinge portion 210, a second hinge portion 220, and a third hinge portion 230, with the first hinge portion 210 hinged to the load-bearing assembly 100. The second connecting assembly 300 has a fourth hinge portion 310, a fifth hinge portion 320, and a sixth hinge portion 330, with the fourth hinge portion 310 hinged to the second hinge portion 220. One end of the shock absorber 400 is hinged to the third hinge portion 230, and the other end is hinged to the fifth hinge portion 320. The support assembly 500 is hinged to the sixth hinge portion 330, and the support assembly 500 is connected to the load-bearing assembly 100, and the load-bearing assembly 100 is movable relative to the support assembly 500.

[0039] During operation, when the load on the bearing assembly 100 vibrates, the bearing assembly 100 moves upward or downward relative to the support assembly 500, and the first connecting assembly 200 rotates relative to the bearing assembly 100, thereby causing the second connecting assembly 300 to rotate relative to the first connecting assembly 200. Since the first connecting assembly 200 is provided with a first hinge portion 210 and a third hinge portion 230, the first hinge portion 210 is hinged to the bearing assembly 100, and the third hinge portion 230 is hinged to one end of the shock absorber 400. Compared to the first connecting assembly 200 and the shock absorber 400, both of which are hinged to the same point on the bearing assembly 100, the first connecting assembly 200 and the second connecting assembly 300 of this shock-absorbing device have a larger amplitude and range of rotation, which can more effectively transmit vibrations to the shock absorber 400 for buffering, fully utilizing the function of the shock absorber 400 and thus improving the overall shock absorption effect.

[0040] Specifically, the shock absorption device is applied to vehicles, specifically to wheelbarrows.

[0041] Specifically, the support component 100 can be a support plate. Specifically, the support component 100 can be a rectangular plate.

[0042] Specifically, the material of the load-bearing component 100 can be a material with high strength, high hardness, and high toughness. For example, steel or aluminum alloy.

[0043] In another embodiment, the support plate can form a receiving groove 110 to facilitate the receiving of a support. Specifically, the receiving groove 110 can be a rectangular receiving groove 110.

[0044] In some embodiments, the first connecting component 200 has opposing first and second ends, a first hinge portion 210 and a third hinge portion 230 are disposed at the first end, and a second hinge portion 220 is disposed at the second end. Specifically, the first connecting component 200 can be an elongated plate-like structure. The first hinge portion 210 and the third hinge portion 230 are arranged side by side and close to each other.

[0045] Specifically, the first connecting assembly 200 includes a first connecting member 240 and a second connecting member 250 disposed opposite to each other. The first connecting member 240 is provided with a first hinge portion 210, a second hinge portion 220, and a third hinge portion 230. The second connecting member 250 is correspondingly provided with the first hinge portion 210, the second hinge portion 220, and the third hinge portion 230. Specifically, the first connecting member 240 and the second connecting member 250 are arranged in parallel. Specifically, a shock absorber 400 is disposed between the first connecting member 240 and the second connecting member 250. The first connecting member 240 and the second connecting member 250 have the same structure.

[0046] In some embodiments, the second connecting assembly 300 is similar to a tripod. The fourth hinge 310, the fifth hinge 320, and the sixth hinge 330 are located at the three included angles of the tripod, respectively.

[0047] Specifically, the second connecting assembly 300 includes a third connecting member 340 and a fourth connecting member 350. The third connecting member 340 is provided with a fourth hinge portion 310, a fifth hinge portion 320, and a sixth hinge portion 330. Specifically, the third connecting member 340 and the fourth connecting member 350 are arranged in parallel. Specifically, the shock absorber 400 is disposed between the third connecting member 340 and the fourth connecting member 350. The third connecting member 340 and the fourth connecting member 350 have the same structure.

[0048] In some embodiments, the damping device includes a first rotating shaft, and a sleeve 120 is provided on the bearing assembly 100. The first rotating shaft passes through the sleeve 120 and is hinged to a first hinge portion 210. The sleeve 120 provides support and guidance for the first rotating shaft. The sleeve 120 restricts unnecessary radial and axial displacement of the first rotating shaft, making it more stable during rotation. The sleeve 120 ensures that the first rotating shaft maintains accurate position and stable rotation even under heavy loads and frequent vibrations, preventing the entire damping device from failing due to shaft wobbling or offset, thereby enhancing the stability of the entire damping device.

[0049] In some embodiments, the sleeve 120 is provided with a clearance opening 130, which is used to allow the end of the shock absorber 400 near the third hinge portion 230 to pass. The clearance opening 130 is a spatial area provided on the sleeve 120 to provide the necessary space range for the end of the shock absorber 400 near the third hinge portion 230 during movement. During operation, the end of the shock absorber 400 near the third hinge portion 230 can move freely within the space defined by the clearance opening 130, without being obstructed by the solid part of the sleeve 120, thereby ensuring the normal movement trajectory of the shock absorber 400 and realizing the reasonable spatial coordination of the various components of the shock absorption device.

[0050] In some embodiments, the damping device includes a second rotating shaft. One end of the damper 400 has a mounting hole, and the second rotating shaft passes through the mounting hole and is hinged to a third hinge portion 230. The second rotating shaft passes through the mounting hole at one end of the damper 400 and is hinged to the third hinge portion 230, achieving a reliable connection between the damper 400 and the first connecting assembly 200. This accurately positions the damper 400 within the entire damping device, ensuring that the damper 400 does not shift or shake during operation, thus guaranteeing the structural stability of the damping device. A rotating pair can be formed between the damper 400 and the first connecting assembly 200, allowing the damper 400 to rotate relative to the first connecting assembly 200 within a certain range around the second rotating shaft. During damping, when the load-bearing assembly 100 changes position due to vibration, the damper 400 can adapt to different force conditions and motion states through this rotation, thereby better performing its damping function.

[0051] In some embodiments, the vibration damping device further includes a first telescopic rod 610, one end of which is connected to the load-bearing component 100, and the other end is connected to the support component 500. The first telescopic rod 610 connects the load-bearing component 100 and the support component 500, forming a stable structural system for the entire vibration damping device. The first telescopic rod 610 can bear the weight and load transmitted from the load-bearing component 100 and transfer the weight and load to the support component 500, ensuring the stable connection between the components during operation and maintaining the normal operation of the entire vibration damping device. During vibration damping, the relative position between the load-bearing component 100 and the support component 500 changes with vibration. The first telescopic rod 610 can adapt to this change in relative position through its own extension and retraction, ensuring that the distance and angle between the load-bearing component 100 and the support component 500 are within a suitable range, enabling the vibration damping device to operate normally under different working conditions.

[0052] Specifically, the first telescopic rod 610 typically employs a telescopic structural design, such as a sleeve type 120 or a linkage type. The interior of the first telescopic rod 610 may contain springs, hydraulic components, or other elastic parts. When the distance between the load-bearing assembly 100 and the support assembly 500 changes, the first telescopic rod 610 extends or retracts under the action of these elastic parts. For example, when the load-bearing assembly 100 is subjected to an upward impact force, the first telescopic rod 610 is compressed, and the internal spring or hydraulic oil absorbs the energy. When the impact force disappears, the spring or hydraulic oil releases the energy, causing the first telescopic rod 610 to return to its original length, thus achieving the telescopic function.

[0053] In some embodiments, the shock absorption device further includes a second telescopic rod 620, one end of which is connected to the load-bearing component 100 and the other end of which is connected to the support component 500. The cross-sectional area of ​​the second telescopic rod 620 is smaller than that of the first telescopic rod 610.

[0054] In some embodiments, the vibration damping device includes an adjusting assembly 700, which is fixedly disposed at the fifth hinge portion 320 of the second connecting assembly 300. The other end of the shock absorber 400 is hinged to the adjusting assembly 700 and is slidable relative to the axial direction of the adjusting assembly 700. This axial sliding of the other end of the shock absorber 400 relative to the adjusting assembly 700 changes the effective working length of the shock absorber 400, thereby adjusting the damping stroke. Under different working conditions and when subjected to different degrees of vibration, the damping stroke can be adjusted according to actual needs to achieve the optimal damping effect.

[0055] In some embodiments, the adjusting assembly 700 includes a threaded rod 710 and an adjusting member 720. The threaded rod 710 is fixedly disposed on the fifth hinge portion 320 of the second connecting assembly 300, and the adjusting member 720 is hinged to the other end of the shock absorber 400. The adjusting member 720 has a threaded hole, and the threaded rod 710 is threadedly engaged with the threaded hole so that the adjusting member 720 can slide relative to the axial direction of the threaded rod 710, thereby allowing the other end of the shock absorber 400 to slide relative to the axial direction of the threaded rod 710.

[0056] In other embodiments, a unicycle includes wheels and the aforementioned shock-absorbing device, with the wheels rotatably mounted on a support assembly 500 of the shock-absorbing device.

[0057] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
