TECHNICAL FIELD

[0001] The utility model relates to the technical field of tire. BACKGROUND

[0002] The conventional tire is mostly pneumatic tire, and the tire is divided into inner tire and outer tire, or outer tire without inner tire, which is commonly called vacuum tire. The former is inflated to the inner tire, and the latter is directly inflated to the inner layer of the outer tire to support the outer tire, and the outer tire is made of material with high strength and wear resistance. The pneumatic tire is easily punctured by sharp objects and leaks, and even dangerous accidents such as tire burst occur, and the tire needs to be inflated every certain period of time, which is inconvenient to use. In view of this deficiency, a solid tire appears on the market at present. Although the solid tire can avoid the trouble of inflation, the solid tire has poor cushioning effect and is not comfortable to use. SUMMARY

[0003] The utility model aims at providing a tire structure with safety maintenance function and comfort.

[0004] In order to achieve the above purpose, the solution of the utility model is as follows:

[0005] A tire structure comprises a rim, an outer tire and a solid inner tire.

[0006] The tire lip of the outer tire is sealingly connected with the rim, the solid inner tire is arranged in the inner part of the outer tire, the inner ring surface of the solid inner tire has a groove, and the groove and the rim form an air inlet channel connecting the air inlet of the rim.

[0007] The surface of the tread of the solid inner tire is densely covered with a plurality of interconnected grooves, and at least one sidewall of the solid inner tire has at least one air duct connecting the groove and the groove.

[0008] When not inflated, the tread of the solid inner tire is tightly matched with the inner wall of the outer tire.

[0009] After inflation, the grooves of the solid inner tire and the inner wall of the outer tire have a buffer gas.

[0010] Further, after inflation, the buffer gas also overflows to form a buffer gas layer between the solid inner tire and the outer tire.

[0011] Further, the solid inner tire is made of elastic material, and the size of the solid inner tire is larger than that of the outer tire. When not inflated, the solid inner tire is compressed and accommodated in the inner part of the outer tire. After inflation, the outer tire is expanded by the gas, and the solid inner tire returns to the original state.

[0012] Further, the groove is an annular structure arranged on the inner ring surface of the solid inner tire.

[0013] Further, the two sidewalls of the solid inner tire are provided with a plurality of air channels, all of the air channels are communicated with the grooves of the tread, and the inner ends of some of the air channels are communicated with the recesses.

[0014] Further, the inner ends of all of the air channels are communicated with the inner annular surface, and the inner ends of some of the air channels are communicated with the recesses through the communication grooves recessed in the inner annular surface.

[0015] Further, the air channels of the sidewalls are uniformly spaced in the circumferential direction and extend in the radial direction.

[0016] Further, the grooves of the tread are staggered and communicated with each other.

[0017] Further, the grooves of the tread are distributed in the shape of "X".

[0018] Further, the air channels are in the form of grooves recessed in the surface of the sidewall; after being inflated, the air channels also have buffer gas between the air channels and the inner wall of the outer tire.

[0019] After the above technical scheme is adopted, the solid inner tire is arranged in the outer tire, the tread of the solid inner tire is tightly matched with the outer tire when not inflated, and the tire can be normally used under the condition of not being inflated; after being inflated, the gas enters the grooves along the recesses and the air channels, and the outer tire is inflated, and the gas can be uniformly distributed along the densely arranged grooves, so that the grooves of the tread of the solid inner tire and the outer tire have buffer gas, the effect of buffering and shock absorption can be achieved, and the driving experience can be effectively improved.

[0020] Since the solid inner tire is arranged, even if the outer tire is accidentally damaged during driving, the solid inner tire can still provide sufficient support function, and the safety during driving can be ensured, and the vehicle can be timely driven to a repair point for repair.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical scheme and advantage of the embodiment of the application more clear, the technical scheme in the embodiment of the application will be clearly and completely described below, obviously, the described embodiment is a part of the embodiment of the application, rather than all the embodiments.

[0030] As Figures 1 to 3 Indicated, it is a solid inner tube 1 of the embodiment.

[0031] The inner ring surface 11 of the solid inner tube 1 has recess 111;

[0032] The surface of the tread 13 of the solid inner tube 1 is densely covered with several interconnected grooves 131, and at least one sidewall 12 of the solid inner tube 1 has at least one air channel 121 that communicates the recess 111 and the groove 131.

[0033] Therefore, referring to Figures 4 to 7 The solid inner tube 1 of the embodiment can be applied to a tire structure 10 and can have the advantage of good buffering effect.

[0034] Specifically, the tire structure 10 includes a rim 3, an outer tire 2 and the solid inner tube 1.

[0035] The tire lip 21 of the outer tire 2 is sealingly connected with the rim 3, the solid inner tube 1 is arranged inside the outer tire 2, and the recess 111 of the solid inner tube 1 and the rim 3 form an air inlet channel 4 that communicates with the air inlet 31 of the rim 3.

[0036] When not inflated, the tread 13 of the solid inner tube 1 is tightly matched with the inner wall of the outer tire 2.

[0037] After inflation, the groove 131 of the tread 13 of the solid inner tube 1 and the inner wall of the outer tire 2 have buffer gas 5.

[0038] Therefore, the solid inner tire 1 is arranged in the outer tire 2, the tread 13 of the solid inner tire 1 and the outer tire 2 are tightly matched when not inflated, and the tire can be normally used in the non-inflated state; and after inflation, the gas enters the air inlet channel 4 from the air inlet 31, then enters each groove 131 along the groove 111 and the air channel 121, and makes the outer tire 2 expand, and the gas can be uniformly distributed along the densely arranged grooves 131, so that the buffer gas 5 can be formed between the tread 13 of the solid inner tire 1 and the outer tire 2, and the buffering and damping effect can be achieved, and the driving experience can be effectively improved.

[0039] And when the inflation and pressure continue, the buffer gas 5 can overflow between the solid inner tire 1 and the outer tire 2 to form a buffer gas layer 6, so as to further improve the buffering and damping effect.

[0040] And because the solid inner tire 1 is provided, even if the outer tire 2 is accidentally damaged during driving, the solid inner tire 1 can still provide sufficient support function to ensure the safety during driving, and the vehicle can be timely driven to the repair point for repair.

[0041] In the embodiment, the solid inner tire 1 is made of elastic material, and the size of the solid inner tire 1 can be equal to or greater than the size of the outer tire 2.

[0042] When the size of the solid inner tire 1 is greater than the size of the outer tire 2, the solid inner tire 1 can be compressed and accommodated in the outer tire 2 when not inflated; and after inflation, the outer tire 2 can be expanded by the gas, and the solid inner tire 1 can return to the original state. Therefore, when the solid inner tire 1 and the outer tire 2 of the tire are arranged in the structure of large inside and small outside, the grip of the tire can be effectively improved, and the buffering effect can also be good.

[0043] For example Figures 1 to 3 As shown in the figure, the groove 111 of the embodiment can be a ring structure arranged on the inner ring surface 11 of the solid inner tire 1, which can facilitate the installation of the solid inner tire 1, and no matter how the installation angle of the solid inner tire 1 is, the air inlet channel 4 connected to the air inlet 31 of the rim 3 can be conveniently formed.

[0044] Both the two sidewalls 12 of the solid inner tire 1 are provided with a plurality of air channels 121, the outer ends of all the air channels 121 are connected to the grooves 131 of the tread 13, and the inner ends of part of the air channels 121 are connected to the groove 111.

[0045] The gas can flow from the groove 111 to the groove 131 through the air channel 121, so that all the grooves 131 are filled.

[0046] Specifically, the inner ends of all the air channels 121 are connected to the inner ring surface 11, and the inner ends of part of the air channels 121 are connected to the groove 111 through the communication groove 112 arranged in the inner ring surface 11.

[0047] In the embodiment, the air passages 121 of the sidewall 12 are uniformly spaced in the circumferential direction and extend in the radial direction. The air passages 121 can be groove structures recessed on the surface of the sidewall 12, so that the air passages 121 can also be filled with the cushioning gas 5 between the sidewall 12 and the outer tire 2, and a uniform air cushion layer 6 can also be formed.

[0048] The number of the communication grooves 112 can be less than the number of the air passages 121. The communication grooves 112 are also uniformly spaced in the circumferential direction, and extend in the axial direction to communicate with the inner ends of the air passages 121. The plurality of communication grooves 112 facilitate the rapid flow of the gas to the air passages 121.

[0049] In the embodiment, the grooves 131 of the tread 13 are interlaced with each other. Specifically, the grooves 131 of the tread 13 can be distributed in an "X" shape. This facilitates the rapid dispersion and circulation of the gas, ensures the uniformity of the air layer, and guarantees the cushioning and shock-absorbing effect.

[0050] The above only describes the preferred embodiments of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiments. Any technical solution falling within the concept of the present application belongs to the protection scope of the present application.
