In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0051] Example 1

[0052] Embodiment 1 provides an explosion-proof safety tire, such as Figure 1 and Figure 2 As shown, it includes an elastic support body 1, a first pressure-bearing body 2 sleeved on the outer side surface of the elastic support body 1, a support member 3 sleeved on the outer side surface of the first pressure-bearing body 2, a second pressure-bearing body 4 sleeved on the outer side surface of the support body, and a tread 5 sleeved on the outer side surface of the second pressure-bearing body 4. The elastic support body 1, the first pressure-bearing body 2, the support member 3, the second pressure-bearing body 4 and the tread 5 are coaxially arranged, and the elastic support body 1, the first pressure-bearing body 2, the support member 3, the second pressure-bearing body 4 and the tread 5 are connected in sequence through a connecting body.

[0053] Compared with the existing ordinary pneumatic tires, the elastic support body 1 of the present invention is arranged on the inner side of the first pressure-bearing body 2, which is not easy to burst and is puncture-proof. In addition, the present invention bears pressure through the tread 5, the second pressure-bearing body 4, the support member 3, the first pressure-bearing body 2 and the elastic support body 1 which are arranged in sequence from the outside to the inside. It is maintenance-free, free of burst, puncture-proof, has high load-bearing capacity, is resistant to high and low temperatures, is light in weight, and has extremely strong practicality.

[0054] In this embodiment, the connector is made of a flexible and elastic material. Specifically, the connector is any one or a combination of resin, rubber, gel, cellulose, metal, and ceramic.

[0055] In a specific implementation of this embodiment, the connector is a single-layer adhesive structure formed by combining raw rubber, vulcanizing agent and / or adhesive, so that the connector has high strength and high toughness. The connector is evenly laid between two adjacent parts to ensure that the contact area between the two adjacent parts is maximized, thereby increasing the bonding strength. The even laying of the connector can ensure a stable connection between the two adjacent parts and improve the stability and safety of the overall structure.

[0056] In this embodiment, Figure 3 and Figure 4 As shown, the first pressure-bearing body 2 is an annular structure, and the inner side surface is connected to the outer side surface of the elastic support body 1 through a connecting body, and the outer side surface is connected to the inner side surface of the support member 3 through a connecting body.

[0057] The inner side surface of the first pressure-bearing body 2 is provided with a first support portion 211 which is recessed inwardly, and the first support portion 211 presses the outer side surface of the elastic support body 1 . The outer side surface of the first pressure-bearing body 2 is provided with a second support portion 212 which protrudes outwardly, and the second support portion 212 presses the inner side surface of the support member 3 .

[0058] The first pressure-bearing body 2 of the annular structure provided in this embodiment is connected to the outer side surface of the elastic support body 1. By setting the first support portion 211, it is not only convenient to place the connecting body, but also can press the outer side surface of the elastic support body 1 to make the elastic support body 1 partially concave. By improving the structure of the first pressure-bearing body 2 itself, the first pressure-bearing body 2 and the elastic support body 1 can be well matched to prevent the elastic support body 1 from being excessively deflected and running out. Moreover, this structure has low cost and strong practicality.

[0059] In this embodiment, Figure 5 As shown, the first pressure-bearing body 2 includes one or more first pressure-bearing rings 21, which are annular structures. One or more first pressure-bearing rings 21 have a certain pressure-bearing capacity and elastic recovery force. The inner side surface of the first pressure-bearing ring 21 is provided with a first support portion 211 recessed inwardly and the outer side surface is provided with a second support portion 212 protruding outwardly.

[0060] In this embodiment, the first pressure ring 21 is made of a material with a high elastic modulus, and the thickness of the material is greater than 1 mm.

[0061] When the first pressure-bearing body 2 includes a first pressure-bearing ring 21 , the first support portion 211 presses the outer side surface of the elastic support body 1 , and the second support portion 212 presses the inner side surface of the support member.

[0062] When the first pressure-bearing body 2 includes a plurality of first pressure-bearing rings 21, the plurality of first pressure-bearing rings 21 are stacked in sequence and coaxially arranged, the first support portion 211 of a first pressure-bearing ring 21 closest to the elastic support body 1 presses the outer side surface of the elastic support body 1, the second support portion 212 of a first pressure-bearing ring 21 closest to the support member 3 presses the inner side surface of the support member 3, and the positions of the first support portion 211 of one first pressure-bearing ring 21 and the second support portion 212 of the other first pressure-bearing ring 21 correspond to each other in two adjacent first pressure-bearing rings 21. By stacking a plurality of first pressure-bearing rings 21, it is ensured that the pressure of the first support portion 211 on the elastic support body 1 is micro-pressure, and a certain expansion space is given to the elastic support body 1 to prevent the elastic support body 1 from exploding, and the pressure-bearing capacity of the elastic support body 1 is not reduced, but can be increased to a certain extent.

[0063] By setting the first pressure-bearing body 2 to include a plurality of first pressure-bearing rings 21, the first pressure-bearing rings 21 adjacent to each other and the connector form a sandwich plate shell structure. Such a structure has the characteristics of light weight, high strength, and high rigidity, and can obtain good vibration resistance, heat insulation, sound insulation and other necessary properties. In addition, since large-area riveting is not used, stress concentration can be reduced, and fatigue strength is greatly improved. Due to the above advantages, the sandwich plate shell structure is being used more and more widely in various military and civilian departments. The mechanical characteristics of the sandwich plate shell structure are that the two first pressure-bearing rings 21 are the main bearing layers, and the role of the sandwich formed by the connector is to open the two first pressure-bearing rings 21, and the two first pressure-bearing rings 21 are firmly combined together and bear shear stress. This is similar to the idea of ​​an I-beam, that is, the two first pressure-bearing rings 21 play the role of wing plates, and the sandwich formed by the connector plays the role of a web plate.

[0064] In this embodiment, Figure 3 , Figure 6 and Figure 7 As shown, the cross-section of the first support portion 211 and / or the second support portion 212 is umbrella-shaped, so as to further gradually increase and smoothly apply pressure to the elastic support body 1 from both sides of the second pressure ring 41 to the middle of the second pressure ring 41, thereby preventing the elastic support body 1 from exploding. The pressure-bearing capacity of the elastic support body 1 is not reduced, but can be increased to a certain extent.

[0065] In this embodiment, the radii of the first support portion 211 and the second support portion 212 are much smaller than the radius of the first pressure ring 21, ensuring that the pressure of the first support portion 211 on the elastic support body 1 is slightly pressured, and at the same time ensuring that the pressure of the second support portion 212 on the support member 3 is slightly pressured.

[0066] In this embodiment, Figure 3 , Figure 6 and Figure 7 As shown, the number of the first support part 211 and / or the second support part 212 is one or more, and the first support part 211 and the second support part 212 are integrally formed with the first pressure-bearing body 2 or fixedly connected by welding and compounding.

[0067] In this embodiment, when the number of the first support portion 211 and / or the second support portion 212 is one, the first support portion 211 is annular, and the first support portion 211 and / or the second support portion 212 is disposed in the middle of the inner side surface of the first pressure-bearing body 2 .

[0068] In this embodiment, when the number of the first support portion 211 and / or the second support portion 212 is multiple, the first support portion 211 and / or the second support portion 212 is annular or hill-shaped, and the multiple first support portions 211 are symmetrically arranged on the inner side surface of the first pressure-bearing body 2, and the multiple second support portions 212 are symmetrically arranged on the outer side surface of the first pressure-bearing body 2.

[0069] In this embodiment, Figure 8 As shown, the support member 3 includes a first support shell 31, an intermediate support portion 32 and a second support shell 33. The second support shell 33 is sleeved on the outer side of the first pressure-bearing body 1, and the second pressure-bearing body 4 is sleeved on the outer side of the first support shell 31. The first support shell 31 and the second support shell 33 are both annular structures and are coaxially arranged. The intermediate support portion 32 is arranged between the first support shell 31 and the second support shell 33. Several intermediate support portions 32 are arranged circumferentially along the first support shell 31. The intermediate support portion 32 has elasticity in the radial direction so that the intermediate support portion 32 is in the first position or the second position, wherein

[0070] When the intermediate support portion 32 is in the first position, the intermediate support portion 32 is not compressed, and the intermediate support portion 32 is closely adjacent to the adjacent intermediate support portion 32;

[0071] When the intermediate supporting portion 32 is at the second position, the intermediate supporting portion 32 is compressed, and a certain gap is generated between the intermediate supporting portion 32 and its adjacent intermediate supporting portion 32 .

[0072] In this embodiment, the first supporting shell 31 and the second supporting shell 33 are made of a material with a high elastic modulus, and the thickness of the material is greater than 1 mm.

[0073] The support member 3 provided in this embodiment can replace the support part of an ordinary pneumatic tire. The support member 3 includes a combination of a first support shell 31, an intermediate support portion 32 and a second support shell 33 to strongly support the car, and the first support shell 31 can protect the tire and prevent the tire from being punctured when encountering sharp objects. When an ordinary pneumatic tire is driving on soft, muddy or rugged ground, its performance will be greatly limited. Due to the existence of air pressure inside the tire, the deformation ability of the tire is limited, and it is difficult to fully adapt to the irregular shape of the ground. The support member 3 provided in this embodiment greatly enhances the deformation ability of the tire through compression or non-compression of the intermediate support portion 32, and can cope with complex ground.

[0074] In this embodiment, the middle support portion 32 is integrally formed with the first support shell 31 and the second support shell 33 or is fixedly connected by welding.

[0075] In this embodiment, Figure 8-Figure 10 As shown, the middle support portion 32 includes one or more groups of compression portions, each group of compression portions includes two compression strips 321 arranged oppositely, and there is a certain gap between adjacent compression strips 321 to improve the compression resistance of the support member 3. If the adjacent compression strips 321 are connected together, the compression degree of the middle support portion 32 is greatly reduced, so that the compression resistance of the support member 3 is limited and cannot cope with uneven or complex ground environments.

[0076] In this embodiment, Fig. 9 and Fig.10 As shown, the two compression strips 321 are arranged at a certain distance to make the middle of the support part hollow, which is convenient for the two compression strips 321 to provide support and the two compression strips 321 are arranged at a certain distance to facilitate passing obstacles.

[0077] In this embodiment, Fig. 9 and Fig.10As shown, the compression strip 321 is V-shaped, and the compression strip 321 includes a first compression arm 3211 and a second compression arm 3212. One end of the first compression arm 3211 is fixed to the first support shell 31 to form a first compression part 3213, the other end of the first compression arm 3211 is fixed to one end of the second compression arm 3212 to form a second compression part 3214, and the other end of the second compression arm 3212 is fixed to the first support shell 31 to form a third compression part 3215, so that the two compression strips 321 are opened outward. By setting the first compression part 3213, the second compression part 3214 and the third compression part 3215, the elastic force and toughness of the support part are greater, and a plurality of support parts are used to form a radiating mesh suspension structure. The bow force high elastic ring belt bearing structure formed by the first support shell 31 and the second support shell 33 provides rigidity of the entire tire and provides support for the tire. At the same time, the expansion and contraction of the compression strip 321 in the mesh suspension structure formed by the plurality of support parts realizes the shockproof and obstacle crossing of the tire, thereby improving its comfort.

[0078] In this embodiment, adjacent support parts are close to each other to prevent debris from entering the inner cavity of the support member 3. The spacing between adjacent support parts is less than 2 mm, and several support parts form a special hollow structure and a breathing tire curtain that imitates fish gills. When the tire moves, the heat generated by the tread 5 can be exchanged with the air at any time, which is similar to our breathing. It has the advantages of maintenance-free, no blowout, anti-puncture, high-speed driving, strong load-bearing capacity, high temperature resistance, low temperature resistance, low fuel consumption, light weight, and free connection with the wheel hub. In this new revolutionary period of tires, it has a significant impact on the future development of tires. More importantly, it will be reflected on the future battlefield, providing a strong safety guarantee for mobile driving operations.

[0079] In this embodiment, Fig. 9 and Fig.10 As shown, the first compression arm 3211 and the second compression arm 3212 are both provided with arc-shaped protrusions arranged in sequence up and down to improve the toughness, supporting force and elastic force of the compression strip 321.

[0080] In this embodiment, Fig. 9 and Fig.10 As shown, the first compression portion 3213 , the second compression portion 3214 and / or the third compression portion 3215 are all arc-shaped structures 3216 to improve the toughness, supporting force and elastic force of the compression strip 321 .

[0081] In this embodiment, when the middle support portion 32 includes multiple groups of compression portions, the multiple groups of compression portions are arranged along the axial direction of the first support shell 31. On the one hand, the outwardly opened compression strips 321 can prevent debris from entering the inner cavity of the support member 3; on the other hand, the first support shell 31 and the second support shell 33 are kept in a concentric circle. At the same time, the multiple groups of compression portions also have a shock (vibration) filtering effect.

[0082] In this embodiment, one end of the first compression arm 3211 is fixed to the inner side surface of the first supporting shell 31 , and the other end of the second compression arm 3212 is fixed to the inner side surface of the second supporting shell 33 .

[0083] In this embodiment, Fig. 9 and Fig.10 As shown, in order to ensure the elasticity of the middle support portion 32, the middle support portion also includes a first support plate 3217 and a second support plate 3218. The first support plate 3217 is fixed on the first support shell 31, and the second support plate 3218 is fixed on the second support shell 33. One end of the first compression arm 3211 is fixed to the first support plate 3217 to form a first compression portion 3213, and the other end of the first compression arm 3211 is fixed to one end of the second compression arm 3212 to form a second compression portion 3214, and the other end of the second compression arm 3212 is fixed to the second support plate 3218 to form a third compression portion 3215, so that the two compression strips 321 are opened outward.

[0084] In this embodiment, Fig.11 As shown, in order to further ensure the elasticity of the middle support portion 32 , a retractable curtain 3219 is also wound around the first support plate 3217 and the second support plate 3218 .

[0085] In this embodiment, Fig.12 As shown, a sixth support portion 311 is provided on the outer side of the first support shell 31, and the sixth support portion 311 protrudes outward from the outer side of the first support shell 31, applying a certain pressure to the tread 5 and the second pressure-bearing body 4, so that the first support shell 31, the second pressure-bearing body 4 and the tread 5 cooperate well, supporting the tread 5, and enabling the tread 2 to cope with various complex or uneven ground environments.

[0086] In this embodiment, Fig.13 As shown, a seventh support portion 331 is provided on the outer side surface of the second support shell 33, and the seventh support portion 331 is recessed inwardly into the inner side surface of the second support shell 33, applying a certain pressure to the second pressure-bearing body 4 and the elastic support body 1, so that the second support shell 33, the first pressure-bearing body 2 and the elastic support body 1 can cooperate well, thereby preventing the elastic support body 5 from running out during driving.

[0087] In this embodiment, Fig.14 and Fig.15 As shown, the second pressure-bearing body 4 is an annular structure and the outer side is connected to the inner side of the tread 5 through a connector. The inner side of the second pressure-bearing body 4 is provided with a third support portion 411 recessed inwardly, and the outer side of the second pressure-bearing body 4 is provided with a fourth support portion 412 protruding outwardly.

[0088] In this embodiment, the second pressure-bearing body 4 of the annular structure is connected to the inner side surface of the tread 5 through a connecting body, and the outer side surface of the second pressure-bearing body 4 is provided with a fourth support portion 412 protruding toward the direction close to the tread 5. The fourth support portion 412 slightly presses the inner side surface of the tread 5 to make a part of the tread 5 convex. By improving the structure of the second pressure-bearing body 4 itself, the second pressure-bearing body 4 and the tread 5 can be well matched, so that the tread 5 can cope with various complex or uneven ground environments and prevent the tire from being stuck in obstacles.

[0089] In this embodiment, the tread 5 is also an annular structure. Fig.16 As shown, the second pressure-bearing body 4 includes one or more second pressure-bearing rings 41, the second pressure-bearing rings 41 are annular structures, adjacent second pressure-bearing rings 41 are connected by a connecting body, one or more second pressure-bearing rings 41 are coaxially arranged with the tread 5 and the support member 3, and the inner side surface of the second pressure-bearing ring 41 is provided with a third support portion 411 recessed inwardly and the outer side surface is provided with a fourth support portion 412 protruding outwardly.

[0090] In this embodiment, the second pressure ring 41 is made of a material with a high elastic modulus, and the thickness of the material is greater than 1 mm.

[0091] In this embodiment, Fig.16 As shown, when the second pressure-bearing body 4 includes a second pressure-bearing ring 41 , the third support portion 411 presses the outer side surface of the support member 3 , and the fourth support portion 412 presses the inner side surface of the tread 5 .

[0092] In this embodiment, Fig.16 As shown, when the second pressure body 4 includes multiple second pressure rings 41, the multiple second pressure rings 41 are stacked in sequence, the third support portion 411 of the second pressure ring 41 closest to the support member 3 presses the outer side surface of the support member 3, and the fourth support portion 412 of the second pressure ring 41 closest to the tread 5 presses the inner side surface of the tread 5. Among two adjacent second pressure rings 41, the third support portion 411 of one second pressure ring 41 and the fourth support portion 412 of the other second pressure ring 41 are located correspondingly, which prevents the problem of displacement of the second pressure ring 41 when the multiple second pressure rings 41 are combined, and can ensure effective support for the tread 5 when multiple second pressure rings 41 are set.

[0093] By setting the second pressure-bearing body 4 to include a plurality of second pressure-bearing rings 41, the adjacent second pressure-bearing rings 41 and the connector form a sandwich plate shell structure. Such a structure has the characteristics of light weight, high strength, high rigidity, and can obtain good vibration resistance, heat insulation, sound insulation and other necessary properties. In addition, since large-area riveting is not used, stress concentration can be reduced, and fatigue strength is greatly improved. Due to the above advantages, the sandwich plate shell structure is being used more and more widely in various military and civilian departments. The mechanical characteristics of the sandwich plate shell structure are that the two second pressure-bearing rings 41 are the main bearing layers, and the role of the sandwich formed by the connector is to open the two second pressure-bearing rings 41, and the two second pressure-bearing rings 41 are firmly combined together and bear shear stress. This is similar to the idea of ​​an I-beam, that is, the two second pressure-bearing rings 41 play the role of wing plates, and the sandwich formed by the connector plays the role of a web plate.

[0094] In this embodiment, Fig.13 , Fig.17 and Fig.18 As shown, the cross-sections of the third support portion 411 and the fourth support portion 412 are umbrella-shaped, so as to further gradually increase and smoothly apply pressure to the tread 5 from both sides of the second pressure ring 41 to the middle of the second pressure ring 41, so that the tread 5 can safely pass through various complex or uneven ground environments without reducing the pressure-bearing capacity of the tread 5. On the contrary, it can increase the pressure-bearing capacity of the tread 5 to a certain extent.

[0095] In this embodiment, the radii of the third support portion 411 and the fourth support portion 412 are much smaller than the radius of the second pressure ring 41, ensuring that the pressure of the fourth support portion 412 on the tread 5 is slight, preventing excessive pressure from affecting the normal driving of the tread 5.

[0096] In this embodiment, the number of the third support portion 411 and / or the fourth support portion 412 is one or more, and the third support portion 411 and the fourth support portion 412 are integrally formed with the second pressure-bearing body 4 or fixedly connected by welding.

[0097] In this embodiment, Fig.14 As shown, when the number of the third support portion 411 and / or the fourth support portion 412 is one, the third support portion 411 and / or the fourth support portion 412 are annular, and the third support portion 411 and / or the fourth support portion 412 are arranged in the middle of the outer side surface of the second pressure-bearing body 4, so as to support the middle part of the tread 5 through one fourth support portion 412 to prevent the tread 5 from shifting.

[0098] In this embodiment, Fig.17 and Fig.18As shown, when the number of the third support portion 411 and / or the fourth support portion 412 is multiple, the third support portion 411 and / or the fourth support portion 412 are ring-shaped or hill-shaped, and the multiple third support portions 411 and / or the fourth support portions 412 are symmetrically arranged on the outer side surface of the second pressure-bearing body 4, so as to support the middle part of the tread 5 through the multiple third support portions 411 and / or the fourth support portions 412 to prevent the tread 5 from shifting.
