Description

Technical Field

[0001] This utility model relates to the field of automobile tire technology, specifically to a non-explosion-proof safety tire. Background Technology

[0002] The current tire industry primarily produces ordinary pneumatic tires, which rely mainly on internal air pressure to support the weight of a vehicle, providing good grip and comfort. However, ordinary pneumatic tires are not without their shortcomings, which are mainly manifested in the following aspects:

[0003] (1) Tiny gaps between tire molecules may allow gas to escape, which means that ordinary pneumatic tires need to be inflated frequently.

[0004] (2) Ordinary pneumatic tires are highly sensitive to sharp objects (such as nails, glass shards, etc.). These objects can easily puncture the tires, leading to air leakage or tire blowout. Especially in bad road conditions, the risk of tire damage is even higher. Tire blowout is a serious safety hazard faced by ordinary pneumatic tires. Once a tire blows out, the vehicle will lose stability, which poses a great safety hazard to people's lives and property. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a non-explosion safety tire that is maintenance-free, explosion-proof, puncture-proof, has high load-bearing capacity, is resistant to high and low temperatures, and is lightweight, making it highly practical.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] An explosion-proof safety tire includes an elastic support body, a first pressure-bearing body sleeved on the outer side of the elastic support body, a support member sleeved on the outer side of the first pressure-bearing body, a second pressure-bearing body sleeved on the outer side of the support body, and a tread sleeved on the outer side of the second pressure-bearing body. The elastic support body, the first pressure-bearing body, the support member, the second pressure-bearing body, and the tread are coaxially arranged, and the elastic support body, the first pressure-bearing body, the support member, the second pressure-bearing body, and the tread are sequentially connected by a connecting body.

[0008] Further, the support member includes a first support shell, an intermediate support portion, and a second support shell. The second support shell is sleeved on the outer side of the first pressure-bearing body, and the second pressure-bearing body is sleeved on the outer side of the first support shell. Both the first and second support shells are annular structures and coaxially arranged. The intermediate support portion is disposed between the first and second support shells. A plurality of intermediate support portions are arranged circumferentially along the first support shell. The intermediate support portion has radial elasticity to allow it to be in a first position or a second position.

[0009] When the intermediate support is in the first position, the intermediate support is not compressed, and the intermediate support is close to its adjacent intermediate support.

[0010] When the intermediate support is in the second position, the intermediate support is compressed, and a certain gap is generated between the intermediate support and its adjacent intermediate support.

[0011] Furthermore, the intermediate support includes one or more sets of compression sections, which are arranged along the axial direction of the first support housing. Each set of compression sections includes two oppositely arranged compression bars with a certain gap between adjacent compression bars. Each compression bar includes a first compression arm and a second compression arm. One end of the first compression arm is fixed to the first support housing to form a first compression part. The other end of the first compression arm is fixed to one end of the second compression arm to form a second compression part. The other end of the second compression arm is fixed to the second support housing to form a third compression part, so that the two compression bars open outward. Both the first compression arm and the second compression arm are provided with arc-shaped protrusions arranged vertically. The first compression part, the second compression part, and / or the third compression part are all arc-shaped structures.

[0012] Furthermore, the first pressure-bearing body has an annular structure, with an inwardly recessed first support portion on the inner side and an outwardly protruding second support portion on the outer side.

[0014] When the first pressure-bearing body includes a first pressure-bearing ring, the first support part presses against the outer side of the elastic support body, and the second support part presses against the inner side of the support member;

[0015] When the first pressure-bearing body includes multiple first pressure-bearing rings, the multiple first pressure-bearing rings are stacked in sequence. The first support portion of the first pressure-bearing ring closest to the elastic support presses against the outer side of the elastic support, and the second support portion of the first pressure-bearing ring closest to the support presses against the inner side of the support. In two adjacent first pressure-bearing rings, the first support portion of one first pressure-bearing ring and the second support portion of the other first pressure-bearing ring are positioned correspondingly.

[0016] Furthermore, the number of the first support portion and / or the number of the second support portion are both one or more, the first support portion and / or the second support portion are annular or hill-shaped, and the cross-section of the first support portion and the second support portion are both umbrella-shaped.

[0017] Furthermore, the second pressure-bearing body has an annular structure, with an inwardly recessed third support portion on the inner side and an outwardly protruding fourth support portion on the outer side.

[0019] When the second pressure-bearing body includes a second pressure-bearing ring, the third support part presses against the outer side of the support member, and the fourth support part presses against the inner side of the tread.

[0020] When the second pressure bearing body includes multiple second pressure bearing rings, the multiple second pressure bearing rings are stacked in sequence. The third support portion of the second pressure bearing ring closest to the support member presses against the outer side of the support member, and the fourth support portion of the second pressure bearing ring closest to the tread presses against the inner side of the tread. In two adjacent second pressure bearing rings, the third support portion of one second pressure bearing ring and the fourth support portion of the other second pressure bearing ring are positioned correspondingly.

[0051] Example 1

[0052] Example 1 provides a non-explosion-proof safety tire, such as Figure 1 and Figure 2As shown, the device includes an elastic support 1, a first pressure-bearing body 2 sleeved on the outer side of the elastic support 1, a support member 3 sleeved on the outer side of the first pressure-bearing body 2, a second pressure-bearing body 4 sleeved on the outer side of the support body, and a tread 5 sleeved on the outer side of the second pressure-bearing body 4. The elastic support 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 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 by a connecting body.

[0053] Compared to existing ordinary pneumatic tires, this invention features an elastic support 1 located on the inner side of the first pressure-bearing body 2, making it less prone to tire blowouts and puncture-proof. Furthermore, this invention utilizes a tire tread 5, a second pressure-bearing body 4, a support member 3, the first pressure-bearing body 2, and the elastic support 1 arranged sequentially from the outside in for pressure bearing. It is maintenance-free, blowout-proof, puncture-proof, has high load-bearing capacity, is resistant to high and low temperatures, and is lightweight, making it highly practical.

[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 one specific embodiment of this invention, the connector is a single-layer adhesive structure formed by combining raw rubber, a vulcanizing agent, and / or an adhesive, thereby giving the connector high strength and high toughness. The connector is evenly laid between two adjacent components, ensuring maximum contact area between them, thus increasing adhesive strength. The even laying of the connector ensures a stable connection between two adjacent components, improving the stability and safety of the overall structure.

[0056] In this embodiment, as Figure 3 and Figure 4 As shown, the first pressure-bearing body 2 has a ring-shaped structure and its inner side is connected to the outer side of the elastic support body 1 through a connector, and its outer side is connected to the inner side of the support member 3 through a connector.

[0057] The inner side of the first pressure-bearing body 2 is provided with an inwardly recessed first support part 211, which presses against the outer side of the elastic support body 1. The outer side of the first pressure-bearing body 2 is provided with an outwardly protruding second support part 212, which presses against the inner side 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 of the elastic support body 1. By setting the first support part 211, it is not only convenient to place the connecting body, but also to press the outer side of the elastic support body 1 so that the elastic support body 1 is partially concave. Through the improvement of 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, preventing the elastic support body 1 from being excessively tilted and running out. Moreover, this structure is low in cost and highly practical.

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

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

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

[0062] When the first pressure-bearing body 2 includes multiple first pressure-bearing rings 21, the multiple first pressure-bearing rings 21 are stacked sequentially and coaxially arranged. The first support portion 211 of the first pressure-bearing ring 21 closest to the elastic support body 1 presses against the outer side of the elastic support body 1, and the second support portion 212 of the first pressure-bearing ring 21 closest to the support member 3 presses against the inner side of the support member 3. In two adjacent first pressure-bearing rings 21, 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. By stacking multiple first pressure-bearing rings 21, it is ensured that the pressure of the first support portion 211 on the elastic support body 1 is a slight pressure, and a certain amount of expansion and contraction space is given to the elastic support body 1 to prevent the elastic support body 1 from exploding. This does not reduce the pressure-bearing capacity of the elastic support body 1, but rather increases the pressure-bearing capacity of the elastic support body 1 to a certain extent.

[0063] By configuring the first bearing body 2 as a structure comprising multiple first bearing rings 21, with adjacent first bearing rings 21 and connecting bodies forming a sandwich shell structure, this structure is characterized by its light weight, high strength, and high rigidity, and can achieve good vibration resistance, heat insulation, sound insulation, and other necessary properties. Furthermore, by avoiding large-area riveting, stress concentration can be reduced, resulting in a significant improvement in fatigue strength. Due to these advantages, sandwich shell structures are being increasingly widely used in various military and civilian sectors. The mechanical characteristics of a sandwich shell structure are that the two first bearing rings 21 serve as the main load-bearing layers, while the connecting bodies form a sandwich structure that expands and firmly bonds the two first bearing rings 21 together, bearing shear stress. This is similar to the concept of an I-beam, where the two first bearing rings 21 act as flanges, and the connecting bodies form a sandwich structure that acts as a web.

[0064] In this embodiment, as Figure 3 , Figure 6 and Figure 7 As shown, the cross-section of the first support 211 and / or the second support 212 is umbrella-shaped, so as to further apply gradually increasing and smooth pressure to the elastic support 1 from both sides of the second pressure ring 41 to the middle of the second pressure ring 41, to prevent the elastic support 1 from exploding, without reducing the pressure bearing capacity of the elastic support 1, but rather to a certain extent increasing the pressure bearing capacity of the elastic support 1.

[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 bearing ring 21, ensuring that the pressure of the first support portion 211 on the elastic support body 1 is a small pressure, and at the same time ensuring that the pressure of the second support portion 212 on the support member 3 is a small pressure.

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

[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 are located in the middle of the inner side of the first pressure-bearing body 2.

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

[0069] In this embodiment, as 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. Both the first support shell 31 and the second support shell 33 are annular structures and coaxially arranged. The intermediate support portion 32 is disposed between the first support shell 31 and the second support shell 33. A plurality of intermediate support portions 32 are arranged circumferentially along the first support shell 31. The intermediate support portions 32 have radial elasticity so that the intermediate support portions 32 are in a first position or a second position.

[0070] When the intermediate support 32 is in the first position, the intermediate support 32 is not compressed and the intermediate support 32 is close to its adjacent intermediate support 32.

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

[0072] In this embodiment, the first support shell 31 and the second support shell 33 are made of a material with a high elastic modulus and a material thickness of 1 mm or more.

[0073] This embodiment provides a support member 3 that can replace the support portion of a conventional pneumatic tire. The support member 3 comprises a combination of a first support housing 31, an intermediate support portion 32, and a second support housing 33, providing strong support for the vehicle. The first support housing 31 protects the tire from punctures when encountering sharp objects. Furthermore, the performance of conventional pneumatic tires is significantly limited when driving on soft, muddy, or uneven surfaces. Due to the internal air pressure, the tire's deformation capacity is restricted, making it difficult to fully adapt to irregular ground shapes. The support member 3 provided in this embodiment, through the compression or non-compression of the intermediate support portion 32, greatly enhances the tire's deformation capacity, enabling it to cope with complex terrain.

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

[0075] In this embodiment, as Figures 8-10 As shown, the intermediate support 32 includes one or more sets of compression sections. Each set of compression sections includes two compression strips 321 arranged in opposite directions. There is a certain gap between adjacent compression strips 321 to improve the compressive strength of the support member 3. If adjacent compression strips 321 are connected together, the compression degree of the intermediate support 32 is greatly reduced, which limits the compressive strength of the support member 3 and makes it unable to cope with uneven or complex ground environments.

[0076] In this embodiment, as Figure 9 and Figure 10 As shown, the two compression bars 321 are set at a certain distance to make the middle of the support part hollow, so that the two compression bars 321 can be supported and the two compression bars 321 are set at a certain distance to facilitate the passage of obstacles.

[0077] In this embodiment, as Figure 9 and Figure 10As shown, the compression strip 321 is V-shaped and 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 housing 31 to form a first compression portion 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 portion 3214. The other end of the second compression arm 3212 is fixed to the first support housing 31 to form a third compression portion 3215, causing the two compression strips 321 to spread outward. By setting the first compression portion 3213, the second compression portion 3214, and the third compression portion 3215, the support part has greater elasticity and toughness. The multiple support parts form a radial mesh suspension structure. The high-elasticity ring bearing structure formed by the first support housing 31 and the second support housing 33 provides rigidity for the entire tire, providing support for the tire. At the same time, the extension and retraction of the compression strips 321 in the mesh suspension structure formed by the multiple support parts achieves shock absorption and obstacle crossing for the tire, thereby improving its comfort.

[0078] In this embodiment, adjacent support parts are close together to prevent debris from entering the inner cavity of the support 3. The distance between adjacent support parts is less than 2mm, and several support parts form a special hollow structure and a biomimetic fish gill breathing tire curtain. When the tire is moving, the heat generated by the tire tread 5 can be exchanged with the air at any time, similar to our breathing. It has excellent functions such as maintenance-free, no tire blowout, puncture-proof, 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 tire revolution, it has a significant impact on the future development of tires. More importantly, it is reflected in the future battlefield, providing strong safety guarantee for mobile combat.

[0079] In this embodiment, as Figure 9 and Figure 10 As shown, both the first compression arm 3211 and the second compression arm 3212 are provided with arc-shaped protrusions arranged vertically to improve the toughness, support force and elasticity of the compression strip 321.

[0080] In this embodiment, as Figure 9 and Figure 10 As shown, the first compression part 3213, the second compression part 3214 and / or the third compression part 3215 are all arc-shaped structures 3216 to improve the toughness, support and elasticity of the compression strip 321.

[0081] In this embodiment, when the intermediate support 32 includes multiple sets of compression sections, the multiple sets of compression sections are arranged along the axial direction of the first support housing 31. On the one hand, the outwardly expanding compression strips 321 can block debris from entering the inner cavity of the support member 3; on the other hand, it keeps the first support housing 31 and the second support housing 33 in a concentric circle, and the multiple sets of compression sections also play a role in filtering vibration.

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

[0083] In this embodiment, as Figure 9 and Figure 10 As shown, in order to ensure the elasticity of the middle support 32, the middle support also includes a first support plate 3217 and a second support plate 3218. The first support plate 3217 is fixed on the first support housing 31, and the second support plate 3218 is fixed on the second support housing 33. One end of the first compression arm 3211 is fixed to the first support plate 3217 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. The other end of the second compression arm 3212 is fixed to the second support plate 3218 to form a third compression part 3215, so that the two compression bars 321 open outward.

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

[0085] In this embodiment, as Figure 12 As shown, a sixth support part 311 is provided on the outer side of the first support housing 31. The sixth support part 311 protrudes outward from the outer side of the first support housing 31, giving the tread 5 and the second pressure bearing body 4 a certain pressure, so that the first support housing 31, the second pressure bearing body 4 and the tread 5 cooperate well to support the tread 5, so that the tread 2 can cope with various complex or uneven ground environments.

[0086] In this embodiment, as Figure 13 As shown, a seventh support portion 331 is provided on the outer side of the second support housing 33. The seventh support portion 331 is recessed inward into the inner side of the second support housing 33, giving the second bearing 4 and the elastic support 1 a certain pressure, so that the second support housing 33, the first bearing 2 and the elastic support 1 can cooperate well, thereby preventing the elastic support 5 from running out during driving.

[0087] In this embodiment, as Figure 14 and Figure 15 As shown, the second pressure-bearing body 4 has an annular structure and its 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 an inwardly recessed third support part 411, and the outer side of the second pressure-bearing body 4 is provided with an outwardly protruding fourth support part 412.

[0088] In this embodiment, the second pressure-bearing body 4 with an annular structure is connected to the inner side of the tread 5 through a connector, and the outer side of the second pressure-bearing body 4 is provided with a fourth support part 412 protruding towards the tread 5. The fourth support part 412 slightly presses the inner side of the tread 5 to make the tread 5 partially bulge. Through the improvement of 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 getting stuck in obstacles.

[0089] In this embodiment, the tread 5 is also a ring-shaped structure, such as... Figure 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. The inner side of the second pressure-bearing ring 41 is provided with an inwardly recessed third support portion 411 and the outer side is provided with an outwardly protruding fourth support portion 412.

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

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

[0092] In this embodiment, as Figure 16 As shown, when the second pressure bearing body 4 includes multiple second pressure bearing rings 41, the multiple second pressure bearing rings 41 are stacked in sequence. The third support portion 411 of the second pressure bearing ring 41 closest to the support member 3 presses against the outer side of the support member 3, and the fourth support portion 412 of the second pressure bearing ring 41 closest to the tread 5 presses against the inner side of the tread 5. In two adjacent second pressure bearing rings 41, the third support portion 411 of one second pressure bearing ring 41 and the fourth support portion 412 of the other second pressure bearing ring 41 are positioned correspondingly to prevent the second pressure bearing rings 41 from shifting when multiple second pressure bearing rings 41 are combined, and to ensure effective support for the tread 5 when multiple second pressure bearing rings 41 are provided.

[0093] By configuring the second bearing body 4 as a structure comprising multiple second bearing rings 41, with adjacent second bearing rings 41 and connecting bodies forming a sandwich shell structure, this structure is characterized by its light weight, high strength, and high rigidity, and can achieve good vibration resistance, heat insulation, sound insulation, and other necessary properties. Furthermore, by avoiding large-area riveting, stress concentration can be reduced, resulting in a significant improvement in fatigue strength. Due to these advantages, sandwich shell structures are being increasingly widely used in various military and civilian sectors. The mechanical characteristics of a sandwich shell structure are that the two second bearing rings 41 are the main load-bearing layers, while the connecting body forms a sandwich that supports and firmly bonds the two second bearing rings 41 together, bearing shear stress. This is similar to the concept of an I-beam, where the two second bearing rings 41 act as flanges, and the connecting body forms a sandwich that acts as a web.

[0094] In this embodiment, as Figure 13 , Figure 17 and Figure 18 As shown, the cross-sections of the third support part 411 and the fourth support part 412 are umbrella-shaped, so as to further apply gradually increasing and smooth pressure to the tread 5 from both sides of the second bearing ring 41 to the middle of the second bearing ring 41, so that the tread 5 can safely pass through various complex or uneven ground environments without reducing the bearing capacity of the tread 5, but rather increasing the 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 bearing ring 41, ensuring that the pressure of the fourth support portion 412 on the tread 5 is low, and preventing excessive pressure from affecting the normal driving of the tread 5.

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

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

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