A wheel structure, comprising a wheel rim (1), an elastic outer rim (2) and a sheet-shaped tire skin structure (3); the wheel rim (1) is a circular body, and a first thread (11) being provided outside the wheel rim, a second thread (21) corresponding to the first thread (11) of the wheel rim (1) being provided at periphery of the elastic outer rim (2), so that the outer rim (2) engages with the periphery of the wheel rim (1), and a space (22) being provided in the outer rim (2), so that a fixed spacing is formed between the wheel rim (1) and the outer rim (2), furthermore, at least one inner buffer (23) being provided in the space (22), and the sheet-shaped tire skin structure (3) is joined to the outer rim (2), so that after the wheel structure is assembled to a vehicle, the fixed spacing is maintained by the elastic outer rim (2), so as to keep the wheel running smoothly, and the inner buffer (23) serving as a support when the outer rim (2) is deformed.

Description

Wheel structure technical field

[0001] The present invention relates to a wheel mechanism, and in particular to a wheel structure with a simple structure, low cost, and no inflation.

Background technique

[0002] In the current society, the use of mobile vehicles such as airplanes, ships, automobiles, locomotives, bicycles, etc. for the transportation of people or goods is already a fairly common behavior. And among them, cars, locomotives, and bicycles are most frequently used.

[0003] As everyone knows, such as the driving of cars and locomotives, the energy generated by the engine is mainly converted into a driving force through an appropriate transmission system, and the tires are driven to roll and the cars and locomotives are advanced. The purpose of the existing tires is to infuse high-pressure gas inside the tires to maintain a normal tire pressure, and use the driving tires to make rolling contact with the ground to make vehicles such as automobiles, locomotives or bicycles.

Summary of the invention

technical problem

[0004] However, the tire using high-pressure gas to provide tire pressure has many defects in use, for example, if the tire is punctured by a sharp object, it is very easy to produce a tire puncture, tire deflation, insufficient tire pressure, etc. There will be great safety problems when driving, especially at high speeds, it is more likely to cause danger in use and cause serious casualties.

Solution to the problem

Technical solution

[0005] The main object of the present invention is to provide a simple structure, low cost, non-inflatable wheel structure.

[0006] In order to achieve the above object, a wheel structure provided by the present invention includes a wheel frame, an elastic outer frame and a piece of tire skin structure, wherein the wheel frame is a circular body, and the outer A first thread is provided, and a second thread corresponding to the first thread of the wheel frame is provided around the elastic outer frame, so that the outer frame can be engaged around the wheel frame, and the outer frame is provided with a space for the wheel frame Form a fixed distance with the outer frame, and the At least one inner buffer is provided in the space, and the sheet-shaped tire skin structure is joined to the outer frame, after the wheel structure is assembled in the vehicle, the fixed distance is maintained by the elastic outer frame to keep the wheels running Smooth, and used by the inner buffer as a support for the deformation of the outer frame.

[0007] In implementation, the inner buffer member is U-shaped and integrally formed in the outer frame.

[0008] During implementation, the tire skin structure is composed of a plurality of tire skin units, and can be detachably detached on the outer frame.

[0009] In implementation, the material, thickness and friction number of each tire skin unit are different.

[0010] In order to further understand the present invention, the following is a preferred embodiment, with reference to the accompanying drawings, the specific composition of the present invention and the achieved effects will be described in detail as follows.

The best embodiment of the invention

Best Mode of the Invention [0025] Please refer to FIG. 1 to FIG. 5, the content is an embodiment of the wheel structure of the present invention, which is composed of a wheel frame 1, an elastic outer frame 2 and a piece of tire skin structure 3.

[0026] The wheel frame 1 is a circular body with a first thread 11 on the outside.

[0027] A second thread 21 corresponding to the first thread 11 of the wheel frame 1 is provided around the elastic outer frame 2, so that the outer frame 2 can be engaged around the wheel frame 1, and the outer frame 2 is provided with a space 22 So that a fixed distance is formed between the wheel frame 1 and the outer frame 2, and a plurality of inner buffer members 23 are provided in the space 22, the inner buffer members 23 are U-shaped and integrally formed in the outer frame 2, Used as a support when the outer frame 2 is deformed.

[0028] The sheet-shaped tire skin structure 3 is joined to the outer frame 2, after the wheel structure is assembled in the vehicle, the fixed interval is maintained by the elastic outer frame 2 to keep the wheels running smoothly, wherein The tire skin structure 3 is composed of a plurality of tire skin units 31, and can be detachably mounted on the outer frame.

[0029] Therefore, during implementation, the tire skin unit 31 on the outer frame 2 can be replaced (as shown in FIG. 5) according to the use road conditions (such as snow and sand), and through the design of the present invention, there is no need For the inflation operation of the tire skin, it can effectively solve the problems of conventional tire pressure insufficiency or puncture, deflation, etc., effectively improve the safety of driving, and the thickness of the tire can be greatly reduced to achieve environmental protection purposes and cost savings. The design of the wheel frame 1 using threaded engagement is also convenient for the user to replace.

[0030] In addition, the present invention can also be externally provided with a tire detection device for detecting whether the tire unit 31 on the outer frame 2 is damaged, so as to remind the user to replace it properly.

[0031] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
