Abstract
Description
Technical Field
[0001] This utility model relates to a wheel, specifically a shock-absorbing wheel with a shock-absorbing structure. Background Technology
[0002] Solid tires offer advantages such as being airless, puncture-resistant, and blowout-proof, and are widely used in various fields. Tire performance parameters include their pressure resistance, shock absorption, and adaptability to different road conditions. Solid tires, due to their inherent structural characteristics, have stronger pressure resistance but relatively weaker shock absorption. In existing technology, solid tires are circular, rolling products mounted on various transport tracks, trolleys, or rehabilitation equipment. They are typically mounted on metal rims to support the vehicle body, buffer external impacts, achieve ground contact, and ensure vehicle performance. Tires are often used under complex and harsh conditions, subjected to various deformations, loads, forces, and extreme temperatures during operation; therefore, they must possess high load-bearing capacity, traction, and cushioning performance.
[0003] However, traditional solid tires have a simple structure, low elasticity, and no shock absorption function. When used on bumpy roads, they will cause a great sense of bumpiness and are uncomfortable to use. Utility Model Content
[0004] To address the bumpy feeling caused by tires during use, this utility model provides a shock-absorbing wheel, which includes a core portion, an outer ring portion, and a shock-absorbing portion formed between the core portion and the outer ring portion. The outer ring portion is circularly arranged around the core portion, and the shock-absorbing portion is filled with an elastic material to fix the core portion and the outer ring portion. The shock-absorbing portion forms an anti-slip structure with the contact surfaces of the core portion and the outer ring portion respectively.
[0005] The shock-absorbing wheel includes:
[0006] The shaft portion includes a shaft hole disposed at the center of the shaft portion and a first set of surfaces on the outer surface of the shaft portion;
[0007] The outer ring portion includes a second opposing assembly surface inside the outer ring portion and a contact surface on the outer surface of the outer ring portion;
[0008] The shock-absorbing part has a first set of opposing surfaces formed on its inner surface and a second set of surfaces formed on its outer surface. The first set of opposing surfaces is correspondingly engaged with the first set of surfaces using the anti-slip structure; the second set of surfaces is correspondingly engaged with the second set of opposing surfaces using the anti-slip structure.
[0009] The first set of surfaces includes multiple protrusions or multiple recesses, and the first opposing set of surfaces surrounding the inner side of the shock-absorbing part has multiple first recesses or multiple first protrusions that mate with the protrusions or recesses; the second set of surfaces includes multiple second protrusions or multiple second recesses, and the second opposing set of surfaces on the inner side of the outer ring has multiple third recesses or multiple third protrusions that mate with the protrusions or recesses; wherein
[0010] The protrusion, the groove, the first groove, the first protrusion, the second protrusion, the second groove, the third groove, and the third protrusion can be distributed discontinuously or continuously and regularly on the first set of surfaces, the first opposite set of surfaces, the second set of surfaces, and the second opposite set of surfaces to form a tooth-like or wave-like anti-slip structure.
[0011] Furthermore, the shock-absorbing part includes a flow channel that connects to the groove or the third groove formed by the first set of surfaces or the second set of opposite surfaces.
[0012] The elastic material is made of conductive rubber or silicone.
[0013] As can be seen from the above description, this utility model can achieve the following effects:
[0014] 1. The shock-absorbing part not only improves the damping effect, but also reduces the relative slippage between the assembly surfaces of the shock-absorbing wheel when it stops braking, in other words, it improves the stability of the connection between the shaft and the shock-absorbing part.
[0015] 2. The elastic material is made of conductive rubber or silicone, which can prevent the shock-absorbing wheel from accumulating static electricity due to friction, thus achieving an anti-static effect. Attached Figure Description

[0046] A metal sheet Detailed Implementation
[0047] Please refer to Figure 1 and Figure 2This utility model provides a shock-absorbing wheel 10, which includes a core portion 11, an outer ring portion 12, and a shock-absorbing portion 13 formed between the core portion 11 and the outer ring portion 12. The outer ring portion 12 is circularly arranged around the core portion 11, and the shock-absorbing portion 13 is filled with an elastic material, which not only fixes the core portion 11 and the outer ring portion 12 with an anti-slip structure, but also absorbs the vibration of the shock-absorbing wheel 10 as a wheel of a transportation device on the surface of any object, thereby achieving the effect of shock absorption.
[0048] The shaft portion 11 includes a shaft hole 111 at the center of the shaft portion 11 and a first set of surfaces 112 on the outer surface of the shaft portion 11. The shaft hole 111 can be fitted with an external shaft rod, so that the shock-absorbing wheel 10 can rotate around the shaft hole 111. The first set of surfaces 112 is correspondingly combined with the anti-slip structure and the shock-absorbing portion 13.
[0049] The outer ring portion 12 includes a second opposing assembly surface 121 on the inner side of the outer ring portion 12 and a contact surface 122 on the outer surface of the outer ring portion 12. The second opposing assembly surface 121 is correspondingly combined with the anti-slip structure and the shock-absorbing portion 13. The contact surface 122 serves as a surface of the shock-absorbing wheel 10 that comes into contact with the item or road surface during transportation.
[0050] The shock-absorbing part 13 has a first opposing set surface 131 on its inner surface and a second set surface 132 on its outer surface. The first opposing set surface 131 and the first set surface 112 are connected in a corresponding anti-slip structure, so that the axial part 11 and the shock-absorbing part 13 are fixed. The second set surface 132 and the second opposing set surface 121 are connected in a corresponding anti-slip structure, so that the shock-absorbing part 13 and the outer ring part 12 are fixed.
[0051] Furthermore, the first set of surfaces 112 may include a plurality of protrusions 1121 or a plurality of recesses 1122. The first opposing set of surfaces 131 surrounding the inner side of the shock-absorbing part 13 has a plurality of first recesses 1311 or a plurality of first protrusions 1312 that can cooperate with the protrusions 1121 or the recesses 1122. By the first set of surfaces 112 and the first opposing set of surfaces 131 correspondingly engaging with the anti-slip structure, not only can the shock absorption effect be improved, but the relative slippage between the first set of surfaces 112 and the first opposing set of surfaces 131 can also be reduced when the shock-absorbing wheel 10 stops braking. In other words, the engagement stability between the shaft part 11 and the shock-absorbing part 12 is improved.
[0052] Furthermore, the second set of surfaces 132 on the outer surface of the shock-absorbing part 13 may include a plurality of second protrusions 1321 or a plurality of second grooves 1322. The second opposing set of surfaces 121 on the inner side of the outer ring part 12 has a plurality of third grooves 1211 or a plurality of third protrusions 1212 that can be matched. By having the second set of surfaces 132 and the second opposing set of surfaces 121 in a corresponding anti-slip structure, not only can the shock absorption effect be improved, but the relative slippage between the second set of surfaces 132 and the second opposing set of surfaces 121 can also be reduced when the shock-absorbing wheel 10 stops. In other words, the stability of the connection between the shock-absorbing part 13 and the outer ring part 12 is improved.
[0053] The core portion 11 and the outer ring portion 12 may be made of metal or plastic.
[0054] The elastic material is made of conductive rubber or silicone, which achieves an antistatic effect.
[0055] The protrusion 1121, the groove 1122, the first groove 1311, the first protrusion 1312, the second protrusion 1321, the second groove 1322, the third groove 1211, and the third protrusion 1212 can have any shape, such as rectangle, arc, circle, etc.
[0056] The protrusion 1121, the groove 1122, the first groove 1311, the first protrusion 1312, the second protrusion 1321, the second groove 1322, the third groove 1211, and the third protrusion 1212 can be distributed discontinuously or continuously in a regular manner on the first set of surfaces 112, the first opposite set of surfaces 131, the second set of surfaces 132, and the second opposite set of surfaces 121 to form a toothed or wavy anti-slip structure.
[0057] Preferably, the toothed groove or the wavy anti-slip structure more effectively reduces the relative slippage between the shock-absorbing part 13 and the shaft part 11 and the outer ring part 12, respectively.

Through the corresponding concave and convex combination between the first set of surfaces 112 and the first opposing set of surfaces 131, and between the second set of surfaces 132 and the second opposing set of surfaces 121, not only is the shock absorption effect improved, but the connection stability between the shock-absorbing part 13 and the shaft part 11 and the outer ring part 12 is also improved.

Through the corresponding concave and convex combination between the first set of surfaces 112 and the first opposing set of surfaces 131, and between the second set of surfaces 132 and the second opposing set of surfaces 121, not only is the shock absorption effect improved, but the connection stability between the shock-absorbing part 13 and the shaft part 11 and the outer ring part 12 is also improved.
[0060] Please refer to Figure 5 In this embodiment, the first set of surfaces 112 includes an arc-shaped protrusion 1121, and the first opposing set of surfaces 131 includes an arc-shaped first groove 1311 that matches the arc-shaped protrusion 1121; the second set of surfaces 132 includes an arc-shaped second groove 1322, and the second opposing set of surfaces 121 includes an arc-shaped third protrusion 1212 that matches the arc-shaped second groove 1322. Through the corresponding concave and convex combination between the first set of surfaces 112 and the first opposing set of surfaces 131, and between the second set of surfaces 132 and the second opposing set of surfaces 121, not only is the shock absorption effect improved, but the connection stability between the shock-absorbing part 13 and the shaft part 11 and the outer ring part 12 is also improved.
[0061] Please refer to Figure 6In this embodiment, the first set of surfaces 112 includes an arc-shaped groove 1122, and the first opposing set of surfaces 131 includes an arc-shaped first protrusion 1312 that matches the arc-shaped groove 1122; the second set of surfaces 132 includes an arc-shaped second protrusion 1321, and the second opposing set of surfaces 121 includes an arc-shaped third groove 1211 that matches the arc-shaped second protrusion 1321. Through the corresponding concave and convex combination between the first set of surfaces 112 and the first opposing set of surfaces 131, and between the second set of surfaces 132 and the second opposing set of surfaces 121, not only is the shock absorption effect improved, but the connection stability between the shock-absorbing part 13 and the shaft part 11 and the outer ring part 12 is also improved.
[0062] Please refer to Figure 8 In this embodiment, the first set of surfaces 112 includes discontinuously and discretely distributed arc-shaped protrusions 1121, and the first opposing set of surfaces 131 includes an arc-shaped first groove 1311 that matches the arc-shaped protrusions 1121; the second set of surfaces 132 includes discontinuously and discretely distributed arc-shaped second grooves 1322, and the second opposing set of surfaces 121 includes an arc-shaped third protrusion 1212 that matches the arc-shaped second groove 1322. Through the corresponding concave-convex combination between the first set of surfaces 112 and the first opposing set of surfaces 131, and between the second set of surfaces 132 and the second opposing set of surfaces 121, not only is the shock absorption effect improved, but the connection stability between the shock-absorbing part 13 and the shaft part 11 and the outer ring part 12 is also improved.
[0063] Please refer to Figure 7 , Figure 9 and Figure 10 The shock-absorbing part 13 may further include a flow channel 133, which connects to the groove 1122 or the third groove 1211 formed by the first set of surfaces 112 or the second set of opposite surfaces 121. When the elastic material is filled into the shock-absorbing part 13, the elastic material can be completely filled into the shock-absorbing part 13 through the flow channel 133, so as to avoid the gap formed due to incomplete filling, which would reduce the stability of the connection between the core part 11 and the outer ring part 12 and further reduce the shock absorption effect.
[0064] In one embodiment, a metal sheet A is inserted into the groove 1122 or the third groove 1211. The depth of the metal sheet A is less than the depth of the groove 1122 or the third groove 1211, so that the flow channel 133 is formed at the bottom of the groove 1122 or the third groove 1211. The elastic material can flow through the flow channel 133 between the grooves to completely fill the shock-absorbing part 13.
[0065] In another embodiment, the flow channel 133 is formed between the adjacent sidewalls of the groove 1122 or the third groove 1211, so that the elastic material can also flow through the flow channel 133 between the grooves to completely fill the shock-absorbing part 13.
[0066] Based on the above description of the embodiments, it is evident that various techniques can be used to implement the concepts described in this application without departing from the scope of these concepts. Furthermore, although certain embodiments have been specifically described with reference to them, those skilled in the art will recognize that changes in form and detail can be made without departing from the scope of these concepts. Thus, the described embodiments are to be considered illustrative rather than restrictive in all respects. Moreover, it should be understood that this application is not limited to the specific embodiments described above, but many rearrangements, modifications, and substitutions can be made without departing from the scope of this utility model.
