Please refer to the first to sixth figures, which are the perspective view of the preferred embodiment of the present invention to the schematic diagram of the engagement of the buffer assembly. It can be clearly seen from the figures that the present invention includes:

An inner frame 1;

A plurality of slot portions 11 formed on the inner frame member 1;

A plurality of detachable buffer assemblies 2 arranged around the inner frame member 1, each of the buffer assemblies 2 includes a movable bearing member 21, at least one spring unit 22 provided on the movable bearing member 21, and a plurality of The engaging portion 23 on one side of the movable bearing member 21 is correspondingly combined with the groove portion 11, wherein the engaging portions 23 on each of the movable bearing members 21 have an included corner 231 therebetween;

The outer frame member 3 is set on the outer side of the buffer components 2, the end face of the outer frame member 3 is bent inward to form a second supporting wall 31, and the height of the second supporting wall 31 is smaller than that of the spring unit 22 high;

A tire body 4 covering the outer frame member 3 and the cushion assembly 2;

A first pressing member 5 arranged on the inner side of the inner frame member 1;

A first limiting portion 51 formed on the outer edge of the first pressing member 5;

A plurality of pressing parts 52 formed on one side of the first pressing member 5, inside the pressing part 52 The side has a first threaded portion 521;

A second pressing member 6 arranged inside the inner frame member 1 and correspondingly combined with the first pressing member 5;

A second limiting portion 61 formed on the outer edge of the second pressing member 6 cooperates with the first limiting portion 51 to block the movable carrier 21 and clamp the tire body 4;

A pressing joint portion 62 formed on one side of the second pressing member 6 connects and resists the pressing portion 52 to press the inner frame member 1 outward, and the pressing joint portion 62 has a second threaded portion 621 on the outside , Is correspondingly combined with the first threaded portion 521;

An outer cover 63 is provided on the second pressing member 6, and an assembly portion 631 is formed on the outer cover 63.

Through the above description, we can understand the structure of this technology, and according to the corresponding cooperation of this structure, it can achieve the advantages of no inflation, good shock absorber effect, easy assembly and maintenance, and lower manufacturing cost. The detailed explanation will be The following instructions.

Please also refer to the first to eighth figures, which are the three-dimensional view to the use state diagram of the preferred embodiment of the present invention. When the above-mentioned components are assembled, it can be clearly seen from the figure that the present invention is used instead of The wheel inflation action is the spring unit 22 on the buffer assembly 2. One end of the spring unit 22 is fixed on the movable bearing member 21 and the other end is against the outer frame member 3 to provide a buffer effect when the tire body 4 is stressed. . However, most of the conventional non-pneumatic tires have an integrated polymer plastic structure, so once the structure is damaged, the entire structure must be replaced and replaced, and the cost of the polymer plastic structure is relatively high, so the maintenance cost is considerable. As shown in the fifth figure, the present invention utilizes the slot portion 11 on the inner frame member 1 and the engaging portion 23 of the buffer assembly 2 to allow the buffer assembly 2 to be like an open and close drawer, simply sliding and inserting in a horizontal direction, regardless of Disassembly or installation is very simple, greatly simplifying the disassembly and assembly process, reducing manufacturing costs, and each buffer assembly 2 is set independently, even if it is tired or damaged, as long as it is separately disassembled and replaced, the cost of the buffer assembly 2 is also much lower than that of high The molecular plastic structure can greatly reduce maintenance costs, while saving material costs and avoiding waste of resources.

Specifically, the movable bearing member 21 is a circular arc plate body with the same curvature as the inner frame member 1, the upper surface is provided with a spring unit 22, and the lower surface is provided with a rectangular sheet-shaped engaging portion 23, because the movable bearing member 21 is round Because of the arc shape, the two engaging portions 23 are arranged obliquely, and as shown in the sixth figure, the extending direction of the two engaging portions 23 (the dotted line marked in the figure) intersects each other to have an included corner 231, Therefore, when the buffer assembly 2 is slidably inserted into the groove portion 11 of the inner frame member 1 by using the engaging portion 23 After that, it can no longer move from a direction other than the insertion direction.

Then, the outer frame member 3 is sleeved outside the buffer assembly 2 so that each spring unit 22 abuts against the inner side of the outer frame member 3, and then the tire body 4 is wrapped and arranged outside the outer frame member 3 and the buffer assembly 2, and finally the first A pressing member 5 and a second pressing member 6 clamp and fix the tire body 4 from the left and right sides of the inner frame member 1 respectively. At this time, because the outer frame member 3 is only covered by the tire body 4 and not fixed to the cushion assembly 2, when the tire body 4 receives a force, the tire body 4 links the outer frame member 3 to be pushed by the external force, and The external force is transmitted to the spring unit 22. Although the spring unit 22 is fixed to the inner frame member 1 through the buffer assembly 2, the inner frame member 1 is essentially fixed to the wheel axle 7 and cannot move, so the external force will be absorbed and accumulated by the spring unit 22. When the external force is weakened, the elastic force is fed back to the outer frame member 3. Therefore, as shown in the eighth figure, when the tire body 4 is stressed, the inner frame member 1 is hardly affected, and only the tire body 4 and the outer frame member 3 are Reciprocating movement in the direction of the force (the tire body 4 and the outer frame member 3 are upwardly offset in the figure, so the upper spring unit 22 is in a relaxed state, and the lower spring unit 22 is in a compressed state). Compared with the traditional coupling on the wheel axle 7 As for the shock absorber, it has a stronger shock absorption and buffering effect. In other words, compared with the conventional non-inflatable tire, the present invention not only has a stronger load capacity, but also has no loss of easy damage to the polymer plastic. The tire body 4 made of rubber material is left on the outermost side, which can maintain the quietness of ordinary tires, and can also provide good comfort together with the cushion assembly 2.

In addition, in order to avoid permanent deformation of the tire body 4 and the outer frame member 3 due to excessive external force, the end surface of the outer frame member 3 can be bent inward to form a second supporting wall 31, thereby increasing the structural strength of the outer frame member 3. At the same time, when the external force is too large and the compression range of the spring unit 22 is too large, the second support wall 31 can be further used to restrict the compression range of the spring unit 22.

As for the fixing method of the first pressing member 5 and the second pressing member 6, in this embodiment, as shown in the seventh figure, a large male and female screw is used as the implementation. Specifically, the first pressing member 5 is For the hollow female screw, the pressing portion 52 is a screw body with a first threaded portion 521 (internal thread), which is cut to form a plurality of sheet-like structures. The first limiting portion 51 is the outer edge of the screw head radially outward. The extended brim structure, the second pressing member 6 is a hollow male screw, the pressing joint 62 is a screw body with a second threaded part 621 (external thread), and the second limiting part 61 is also the outer edge of the screw head outwards The radially extending brim structure, therefore, when the first pressing member 5 and the second pressing member 6 are combined with each other, in addition to the first threaded portion 521 and the second threaded portion 621, they will be fixed by the tightening joint 62 at the same time. The pressing part 52 is externally pushed, so that the first pressing part 5 and the second pressing part 6 are tightly combined with the inner frame member 1. At the same time, the first stop part 51 and the second stop part 61 are used to align the tire from the left and right sides. Body 4 and slow The punch assembly 2 is fixed and limited.

In addition, an outer cover 63 can be provided on the second pressing member 6 to cover the hollow part of the second pressing member 6 to prevent the problem of foreign matter intrusion during the driving of the vehicle, and further improve the service life of the present invention and the driving safety of the vehicle. In addition, the shape design on the outer cover body 63 can be used as the decoration of the wheel frame to solve the unpleasant shortcomings of traditional pneumatic tires. The outer cover body 63 can also be integrally formed with the second pressing member 6, and the assembly part 631 on the outer cover body 63 (in this embodiment is a plurality of screw holes, or a rod for the user to hold and rotate the second pressing member 6 Body), it is convenient for the user to assemble the first pressing member 5 and the second pressing member 6, and for the wheel axle 7 to be locked and combined.

Please also refer to the ninth and tenth figures, which are a three-dimensional perspective view of the concealed tire body of another preferred embodiment of the present invention and the BB line cross-sectional view of the ninth figure, which can be clearly seen from the figure. This embodiment is similar to the above-mentioned embodiment, except that the spring units 22a on each buffer assembly 2a are increased to a plurality, and they are arranged side by side on the movable carrier 21a, so that the spring units 22a can be like a spring-spring bed. Like an independent tube, it provides a good cushioning and shock absorption effect. A plurality of first supporting walls 211a can be formed on the movable carrier 21a, and the height of the first supporting walls 211a is smaller than the height of the spring unit 22a. In order to avoid that the compression range of the spring unit 22a is too large due to excessive external force, the first support wall 211a can be used to restrict it. When the spring unit 22a is greatly compressed, the first support wall 211a will hold the outer frame member 3a upward. , In order to reduce the compression amplitude of the spring unit 22a.

However, the above description is only the preferred embodiments of the present invention, which does not limit the patent scope of the present invention. Therefore, all simple modifications and equivalent structural changes made by using the description and drawings of the present invention should be the same. It is included in the scope of the patent of the present invention, and is hereby stated.

In summary, the elastic wheel support structure of the present invention can indeed achieve its effect and purpose when used.
