Abstract
Description
[Technical Field]
[0001] The present invention relates to wheels, and more particularly to wheels having vibration damping structures. [Background technology]
[0002] Solid tires have advantages such as no need for air filling and puncture resistance, and are widely used in various fields. Tire performance parameters include compression resistance, vibration damping, and adaptability to various road conditions. Due to their inherent structural characteristics, solid tires have strong compression resistance but relatively weak vibration damping. In the prior art, solid tires are ring-shaped products assembled on various transportation rails, carts, or rehabilitation equipment and roll along the ground. They are usually mounted on metal rims to support the vehicle body, cushion external impacts, ensure contact with the ground, and ensure the vehicle's running performance. Tires are often used under complex and harsh conditions, and are exposed to various deformations, loads, forces, and high and low temperature effects during operation, requiring high load-bearing, traction, and cushioning capabilities.
[0003] However, conventional solid tires have a single structure, which means they have low elasticity and no vibration damping function, which causes a very large bumpy feeling when used on uneven road surfaces, making them uncomfortable to use. Summary of the Invention [Problem to be solved by the invention]
[0004] To solve the bumpy feeling that occurs when tires are used, the present invention provides a vibration-damping wheel. [Means for solving the problem]

[0006] In the vibration damping wheel, The shaft portion includes a shaft hole provided at the center of the shaft portion and a first assembly surface on an outer surface of the shaft portion; the outer annular portion includes a second mating surface on the inner side of the outer annular portion and a contact surface on the outer surface of the outer annular portion; the vibration absorbing part has a first mating assembly surface formed on an inner surface thereof and a second mating assembly surface formed on an outer surface thereof, the first mating assembly surface and the first mating assembly surface being coupled to each other by the anti-slip structure, and the second mating assembly surface and the second mating assembly surface being coupled to each other by the anti-slip structure; the first assembly surface includes a plurality of protrusions or a plurality of grooves, the first relative assembly surface surrounding the inside of the vibration absorbing part has a plurality of first grooves or a plurality of first protrusions that match the protrusions or grooves, the second assembly surface includes a plurality of second protrusions or a plurality of second grooves, and the second relative assembly surface inside the outer annular part has a plurality of matching third grooves or a plurality of third protrusions; the protrusions, the grooves, the first grooves, the first protrusions, the second protrusions, the second grooves, the third grooves and the third protrusions are distributed discontinuously and discretely on the first assembly surface, the first opposing assembly surface, the second assembly surface and the second opposing assembly surface, or are distributed continuously and regularly to form the tooth-groove or wave-like anti-slip structure; Furthermore, the vibration absorbing portion includes a flow path, and the flow path communicates with the groove or the third groove formed in the first assembly surface or the second opposing assembly surface.
[0007] In the vibration damping wheel, the elastic material is made of conductive rubber or silicone material. [Effects of the Invention]
[0008] From the above description, it can be seen that the present invention can achieve the following effects: 1. The vibration absorbing part not only improves the vibration damping effect, but also reduces the relative slippage between the assembly surfaces of the vibration damping wheel during braking due to the multiple grooves or protrusions on the vibration absorbing part, in other words, improves the connection stability between the shaft part and the vibration absorbing part. 2.

[0010] Referring to Figures 1 and 2, the present invention provides a vibration-damping wheel 10 including a shaft portion 11, an outer ring portion 12, and a vibration-absorbing portion 13 formed between the shaft portion 11 and the outer ring portion 12. The outer ring portion 12 is arranged in a ring shape around the shaft portion 11, and the vibration-absorbing portion 13 is filled with an elastic material. This not only fixes the shaft portion 11 and the outer ring portion 12 with an anti-slip structure, but also allows the vibration-damping wheel 10 to be used as a wheel for transportation equipment to absorb vibrations experienced by the surface of an object, thereby achieving a vibration-damping effect.
[0011] Here, the shaft portion 11 includes a shaft hole 111 provided at the center of the shaft portion 11 and a first assembly surface 112 on the outer surface of the shaft portion 11, and the shaft hole 111 is used to assemble an external shaft and rotate the vibration damping wheel 10 around the shaft hole 111. The first assembly surface 112 is coupled to the vibration absorbing portion 13 via the anti-slip structure.
[0012] Here, the outer ring part 12 includes a second mating assembly surface 121 on the inside of the outer ring part 12 and a contact surface 122 on the outer surface of the outer ring part 12, and the second mating assembly surface 121 is coupled to the vibration absorbing part 13 via the anti-slip structure. The contact surface 122 is the surface that comes into contact with an object or a road surface during transportation of the vibration damping wheel 10.
[0013] Here, the vibration absorbing part 13 forms a first mating assembly surface 131 on its inner surface and a second assembly surface 132 on its outer surface, and the first mating assembly surface 131 and the first assembly surface 112 are coupled to each other by the concave-convex portions of the anti-slip structure, thereby fixing the shaft part 11 and the vibration absorbing part 13. The second assembly surface 132 and the second mating assembly surface 121 are coupled to each other by the concave-convex portions of the anti-slip structure, thereby fixing the vibration absorbing part 13 and the outer ring part 12.
[0014] Furthermore, the first assembly surface 112 may include a plurality of protrusions 1121 or a plurality of grooves 1122, and the first relative assembly surface 131 surrounding the inside of the vibration absorbing part 13 has a plurality of first grooves 1311 or a plurality of first protrusions 1312 that can be matched with the protrusions 1121 or the grooves 1122, and are correspondingly coupled through the unevenness of the anti-slip structure via the first assembly surface 112 and the first relative assembly surface 131, which not only improves the vibration damping effect but also reduces the relative slippage between the first assembly surface 112 and the first relative assembly surface 131 when the vibration damping wheel 10 is braked and stopped, in other words, improves the stability of the connection between the shaft part 11 and the vibration absorbing part 13.
[0015] Furthermore, the second assembly surface 132 on the outer surface of the vibration absorbing part 13 may include a plurality of second protrusions 1321 or a plurality of second grooves 1322, and the second relative assembly surface 121 on the inside of the outer ring part 12 has a plurality of compatible third grooves 1211 or a plurality of third protrusions 1212, which are correspondingly coupled through the unevenness of the anti-slip structure via the second assembly surface 132 and the second relative assembly surface 121, which not only improves the vibration damping effect but also reduces the relative slippage between the second assembly surface 132 and the second relative assembly surface 121 when the vibration damping wheel 10 is braked and stopped, in other words, the stability of the connection between the vibration absorbing part 13 and the outer ring part 12 can be improved.
[0016] Here, the shaft portion 11 and the outer ring portion 12 can be made of a material including metal or plastic material.
[0017] Here, the elastic material is made of conductive rubber or silicone material, which can achieve anti-static effect.
[0018] Here, 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 may have any shape, for example, a rectangle, an arc, a circle, etc.
[0019] Here, the protrusions 1121, the grooves 1122, the first grooves 1311, the first protrusions 1312, the second protrusions 1321, the second grooves 1322, the third grooves 1211 and the third protrusions 1212 may be distributed discontinuously and discretely corresponding to the first assembly surface 112, the first opposing assembly surface 131, the second assembly surface 132 and the second opposing assembly surface 121, or may be distributed continuously and regularly to form the tooth-groove or wave-like anti-slip structure.
[0020] The tooth groove or the wave-shaped anti-slip structure is preferable because it can more effectively reduce relative slippage between the vibration absorbing portion 13 and each of the shaft portion 11 and the outer ring portion 12.

[0022] 4, in this embodiment, the first assembly surface 112 includes the rectangular groove 1122, and the first mating assembly surface 131 includes the rectangular first protrusion 1312 that fits into the rectangular groove 1122. The second assembly surface 132 includes the rectangular second protrusion 1321, and the second mating assembly surface 121 includes the rectangular third groove 1211 that fits into the rectangular first assembly surface 112. The first assembly surface 112 and the first mating assembly surface 131, and the second assembly surface 132 and the second mating assembly surface 121 are coupled to each other through concave and convex portions, which not only improves the vibration damping effect but also improves the stability of the coupling between the vibration absorbing portion 13 and the shaft portion 11 and the outer ring portion 12, respectively.
[0023] 5 , in this embodiment, the first assembly surface 112 includes the arc-shaped protrusion 1121, and the first mating assembly surface 131 includes the arc-shaped first groove 1311 that fits into the arc-shaped protrusion 1121. The second assembly surface 132 includes the arc-shaped second groove 1322, and the second mating assembly surface 121 includes the arc-shaped third protrusion 1212 that fits into the arc-shaped second groove 1322. The first assembly surface 112 and the first mating assembly surface 131, and the second assembly surface 132 and the second mating assembly surface 121 are coupled to each other through concave and convex portions, thereby improving not only the vibration damping effect but also the stability of coupling between the vibration absorbing portion 13 and the shaft portion 11 and the outer ring portion 12, respectively.
[0024] 6 , in this embodiment, the first assembly surface 112 includes the arc-shaped groove 1122, and the first mating assembly surface 131 includes the arc-shaped first protrusion 1312 that fits into the arc-shaped groove 1122. The second assembly surface 132 includes the arc-shaped second protrusion 1321, and the second mating assembly surface 121 includes the arc-shaped third groove 1211 that fits into the arc-shaped second protrusion 1321. The first assembly surface 112 and the first mating assembly surface 131, and the second assembly surface 132 and the second mating assembly surface 121 are coupled to each other through concave and convex portions, thereby improving not only the vibration damping effect but also the stability of coupling between the vibration absorbing portion 13 and the shaft portion 11 and the outer ring portion 12, respectively.
[0025] 8, in this embodiment, the first assembly surface 112 includes the arc-shaped protrusions 1121 that are discontinuously and discretely distributed, and the first mating assembly surface 131 includes the arc-shaped first grooves 1311 that match the arc-shaped protrusions 1121. The second assembly surface 132 includes the arc-shaped second grooves 1322 that are discontinuously and discretely distributed, and the second mating assembly surface 121 includes the arc-shaped third protrusions 1212 that match the arc-shaped second grooves 1322.

[0026] 7, 9 and 10, the vibration absorbing portion 13 may further include a flow path 133 connected to the groove 1122 or the third groove 1211 formed in the first assembly surface 112 or the second opposing assembly surface 121, and when the elastic material is filled into the vibration absorbing portion 13, the elastic material can be completely filled into the vibration absorbing portion 13 through the flow path 133, thereby avoiding the formation of gaps due to incomplete filling, which would reduce the stability of the bond between the shaft portion 11 and the outer ring portion 12 and further reduce the vibration damping effect.
[0027] In one embodiment, a metal sheet A is inserted into the groove 1122 or the third groove 1211, and the depth of the metal sheet A is smaller than the depth of the groove 1122 or the third groove 1211, so that the flow path 133 is formed at the bottom of the groove 1122 or the third groove 1211, and the elastic material can flow through the flow path 133 between each groove to completely fill the vibration absorbing section 13.
[0028] In another embodiment, the flow path 133 is formed between adjacent side walls of the groove 1122 or the third groove 1211, allowing the elastic material to flow through the flow path 133 between each groove to completely fill the vibration absorbing section 13.
[0029] Based on the description of the above embodiments, it is apparent that the concepts described herein can be implemented using a variety of technologies without departing from the scope of those concepts. Furthermore, while the concepts have been described with specific reference to certain embodiments, those skilled in the art will recognize that changes can be made in form and detail without departing from the scope of the concepts.
