Description

Technical Field

[0001] The utility model relates to the field of wheels, in particular to a tire explosion-proof and tire air leakage-proof wheel assembly. Background Art

[0002] Wheels are the main components that support vehicles, aircraft and mobile equipment using tires. Vehicles, aircraft and mobile equipment using tires have gradually become the main means of daily travel and cargo transportation for people. However, the problem of tire driving safety has never been effectively solved. When a tire of a vehicle, aircraft or other mobile equipment using tires bursts or leaks, the tire will immediately lose its support ability, causing the vehicle, aircraft and other mobile equipment using tires to lose balance and cause serious accidents, posing a major threat to personal safety and causing significant losses to personal wealth. According to statistics, more than 40% of highway traffic accidents in China are currently caused by tires, among which tire blowouts are the most serious, accounting for 70%. Therefore, how to prevent tire blowouts and tire leaks has become an urgent need for people, especially ordinary tires.

[0003] To this end, people have also proposed some solutions, such as: explosion-proof tires, explosion-proof wheels (or hubs) and explosion-proof rims, including some solutions that use air suspension technology to solve the imbalance of the vehicle caused by tire blowout. These solutions have not yet completely solved the problem fundamentally. For example, the utility model patent disclosure (authorization announcement number) CN209274284U in the Chinese patent literature discloses "explosion-proof hub, explosion-proof tire and mobile tool", the utility model patent disclosure (authorization announcement number) CN201158279Y in the Chinese patent literature discloses "explosion-proof rim", etc., which are arranged between the tire and the wheel. The technical solutions for the internal space between the tire and the wheel all have a common major defect: ordinary technicians can understand that all the "devices" that play the role of explosion-proofing must have a certain gap with the tire, and the gap cannot be too large, otherwise it will lose its function. That is to say, the maximum outer diameter of the integrated "explosion-proof device" in all the current technical solutions set in the internal space between the tire and the wheel is much larger than the diameter of the tire through-hole, and it is impossible to install it in the internal space of the tire, let alone effectively fix it with the wheel. Therefore, all the currently disclosed technical solutions for the integrated explosion-proofing set in the internal space between the tire and the wheel are invalid technical solutions.

[0004] Here, we will not discuss each of the documents one by one. Utility Model Content

[0005] In view of the above-mentioned deficiencies, the present utility model aims to solve the problems existing in the prior art. Without changing some general technologies of existing wheels, it provides an anti-puncture and anti-air leakage wheel assembly, which solves the problem that after a tire has a puncture or air leakage, the tire will immediately lose its supporting ability, causing vehicles, airplanes and other mobile devices using tires to lose balance. This allows ordinary tires to be used with confidence, extends the service life of the tires, reduces waste of resources, and makes the wheel assembly safe, reliable, and convenient to disassemble and replace.

[0006] To achieve the above object, the technical solution adopted by the present utility model is as follows: An anti-puncture and anti-air leakage wheel assembly includes a wheel body, an anti-puncture tire assembly and a tire. The wheel body includes a hub, spokes and a rim. The hub and the rim are fixedly connected by the spokes. A valve and a monitoring device are respectively provided on the rim. The tire is installed and supported inside both sides of the rim. The anti-puncture tire assembly is arranged in the internal space between the rim and the tire. The inner end and the outer end of the anti-puncture tire assembly are both circular, and there is a certain gap between the outer circumference of the anti-puncture tire assembly and the tire. The rim includes rim A and rim B. Rim A is fixedly connected to the spokes. A part of the outer end surface at the bottom of rim B is set as a flat and smooth surface. The inner end of the anti-puncture tire assembly is fixed on the flat and smooth surface at the bottom of rim B. Flanges are respectively provided at the bottom edges of rim A and rim B. The flanges tightly fix rim B, the anti-puncture tire assembly and rim A together by bolts, and a sealing structure is provided at the upper position of the bolt holes of the flanges of rim A and rim B.

[0007] Furthermore, the anti-puncture tire assembly is set to be composed of a plurality of connecting blocks A and a connecting block B. Preferably, there is one connecting block B.

[0008] Furthermore, the connecting blocks A and B are set for directional installation and disassembly. The installation direction is the outer end of the tire, and the disassembly direction is the center of the tire. The connecting blocks A and B are preferably fixedly connected by a dovetail groove structure.

[0009] Furthermore, the widths of the connecting blocks A and B are smaller than the diameter of the tire through hole.

[0010] Furthermore, the inner arc length of the connecting block A is smaller than the outer arc length.

[0011] Furthermore, the connecting block B is set such that the inner arc length is equal to or greater than the outer arc length, and a mark is provided at the flange part of the corresponding rim A or rim B.

[0012] Furthermore, the anti-puncture tire assembly includes a support member, a sub-rim, and an elastomer. The outer end of the support member is fixedly connected to the sub-rim, and its inner end is provided with a round hole and is fixed on the flat and smooth surface at the bottom of Rim B through the round hole. Elastic bodies are installed on both sides of the sub-rim, and there is a certain gap between the outer ends of the elastic bodies and the tire.

[0013] Furthermore, a stop structure is provided at the part where the inner end of the support member contacts Rim A or Rim B, and the stop structure is preferably a convex-concave structure.

[0014] Furthermore, the shape of the outer end of the elastomer is the same as the shape of the top inside the tire, and the elastomer is preferably a solid tire.

[0015] Compared with the prior art, the present utility model has the following advantages:

[0016] 1. The anti-puncture tire assembly does not affect the effective installation of the tire and the rim.

[0017] 2. The anti-puncture tire assembly is safe and reliable, and is convenient for disassembly and replacement.

[0018] 3. When the tire of a moving vehicle, aircraft, or other tire-using mobile device suddenly bursts or deflates during driving, the distance between the outside of the tire and the ground decreases, and at the same time, the inside of the tire contacts the elastomer on the sub-rim, and the elastomer therein supports the tire, solving the problem that the vehicle, aircraft, and other tire-using mobile devices lose balance due to the sudden loss of the supporting ability of the tire, resulting in accidents.

[0019] 4. After the elastomer on the anti-puncture tire assembly contacts the tire, relying on the friction with the tire, the outside of the tire maintains effective contact with the ground, and the tire can still maintain the normal driving of the vehicle.

[0020] 5. The elastomer on the anti-puncture tire assembly has the advantages of wear resistance and being not afraid of punctures.

[0021] 6. Ordinary tires can be used with confidence without worrying about the imbalance of vehicles, aircraft, and other tire-using mobile devices caused by tire bursts or air leaks, reducing the occurrence of accidents due to tire problems.

[0022] 7. The service life of the tire is extended. Especially for ordinary tires, as long as the tire does not burst, deflate, or break, it can be used normally, reducing the use cost of the vehicle and at the same time reducing resource waste. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0026] The following describes the specific embodiments of the present invention with reference to the accompanying drawings. It should be noted that generally, the wheel body includes a wheel hub, a wheel spoke, and a wheel rim. Due to the integration process of the wheel hub, wheel spoke, and wheel rim, many people also regard the wheel and the wheel hub as the same object. For example, in the utility model patent disclosure (authorization publication number) CN209274284U in the Chinese patent literature, the term "wheel hub" described in "Explosion-proof Tire Wheel Hub, Explosion-proof Tire and Mobile Tool" is the same as the term "wheel" generally referred to. For the convenience of describing the technical solution, the term "wheel" in this article and the "wheel hub" commonly referred to by many people are the same object; unless otherwise defined, all technical and scientific terms used in this article have the same meaning as those commonly understood by those skilled in the technical field to which the present invention belongs; the terms used in the description of the present invention in this article are only for the purpose of describing specific embodiments and do not limit the present invention.

[0027] As Figure 1 、 Figure 2 shown, an explosion-proof tire and anti-tire air leakage wheel assembly is composed of a wheel body 1, an explosion-proof tire assembly 2, and a tire 3. Without changing some general technologies of the existing wheel body 1, the wheel body 1 includes a wheel hub 11, a wheel spoke 12, and a wheel rim 13. The wheel hub 11 and the wheel rim 13 are fixedly connected through the wheel spoke 12. A valve and a monitoring device are respectively provided on the wheel rim 13. The monitoring device can detect the air pressure or temperature in the tire 3 to predict the occurrence of a tire blowout or tire air leakage in advance; the tire 3 is installed and supported on both sides inside the wheel rim 13. The explosion-proof tire assembly 2 is arranged in the internal space between the wheel rim 13 and the tire 3 without affecting the appearance of the entire wheel assembly. The inner and outer ends of the explosion-proof tire assembly 2 are both circular. There is a certain gap between the outer circumference of the explosion-proof tire assembly 2 and the tire 3, and the gap range is based on the ability of the tire 3 to make a safe and stable transition with the explosion-proof tire assembly 2 after a tire blowout or deflation.

[0028] The rim 13 includes a rim A 131 and a rim B 132. The rim A 131 is fixedly connected to the spoke 12. A part of the outer end surface at the bottom of the rim B 132 is set as a flat and smooth surface. The inner end of the puncture-proof tire assembly 2 is fixed on the flat and smooth surface at the bottom of the rim B 132, increasing the support area of the puncture-proof tire assembly 2, which is convenient for installation, fixation and positioning. Flanges 133 are respectively provided at the bottom edges of the rim A 131 and the rim B 132. The flange 133 tightly fixes the rim B 132, the puncture-proof tire assembly 2 and the rim A 131 together through bolts, which is convenient for the installation and disassembly of the puncture-proof tire assembly 2 and the tire 3, facilitating component maintenance and replacement. And a sealing structure 134 is provided at the upper position of the bolt holes of the flanges of the rim A 131 and the rim B 132 to prevent air leakage at the flange 133 part.

[0029] The puncture-proof tire assembly 2 is set to be composed of a plurality of connecting blocks A 20 and a connecting block B 21. The connecting block B 21 is preferably one, which is convenient for installation and free disassembly.

[0030] The connecting blocks A 20 and the connecting block B 21 are set for directional installation and directional disassembly. Its installation direction is the outer end of the tire 3, and its disassembly direction is the center of the tire 3. The connecting blocks A 20 and the connecting block B 21 are preferably fixedly connected to each other in a dovetail groove structure, which is convenient for fixed installation and disassembly.

[0031] The widths of the connecting blocks A 20 and the connecting block B 21 are smaller than the diameter of the through hole of the tire 3. By such setting, the connecting blocks A 20 and the connecting block B 21 can be installed into the inner space of the tire 3.

[0032] The inner arc length of the connecting block A 20 is smaller than the outer arc length, which is convenient for assembly.

[0033] The connecting block B 21 is set so that the inner arc length is equal to or greater than the outer arc length. By such setting, the connecting blocks A 20 and the connecting block B 21 are assembled into a complete and fixed puncture-proof tire assembly 2 and installed into the inner space of the tire 3.

[0034] During the assembly process of the connecting block B 21 and the plurality of connecting blocks A 20, first, the connecting blocks A 20 are successively installed from the through hole of the tire 3 into the inner space of the tire 3, and then the connecting block B 21 is set to be the last one for assembly and fixed to the two adjacent connecting blocks A 20. The connecting block B 21 is provided with a mark at the flange 133 part of the corresponding rim A 131 or rim B 132, which is convenient for disassembly. When replacing the tire 3, first disassemble the connecting block B 21, and then disassemble the other connecting blocks A 20, so that the entire puncture-proof tire assembly 2 is disassembled from the tire 3.

[0035] The explosion-proof tire assembly 2 includes a support member 22, a sub-rim 23 and an elastomer 24. The outer end of the support member 22 is fixedly connected to the sub-rim 23, preferably integrally. Its inner end is provided with a round hole and is fixed on the flat and smooth surface at the bottom of the rim B 132 through the round hole. The elastomers 24 are installed on both sides of the sub-rim 23. The elastomers 24 are used to buffer the impact force transmitted by the ground to the explosion-proof tire assembly 2 after the tire 3 bursts or deflates, support the balance of the wheel assembly, and further improve the safety performance. There is a certain gap between the outer end of the elastomer 24 and the tire 3. The gap is based on not interfering with the normal installation of the tire 3 and the rim 13, and the gap setting ensures that after the tire 3 bursts or the tire air leaks, the vehicle, aircraft and other mobile devices using the tire 3 will not lose balance.

[0036] A stop structure 135 is provided at the part where the inner end of the support member 22 contacts the rim A 131 or the rim B 132. The stop structure 135 is preferably a convex-concave matching structure, so that the support member 22 is firmly installed between the rim A 131 and the rim B 132, and at the same time prevents the explosion-proof tire assembly 2 from generating radial movement under the action of force.

[0037] The shape of the outer end of the elastomer 24 is the same as the shape of the inner top of the tire 3, so that after the tire 3 bursts or the tire air leaks, the contact surface between the outer end of the elastomer 24 and the inside of the tire 3 is basically coincident, preventing the friction between the elastomer 24 and the tire 3 from decreasing and causing slipping during driving after the tire 3 bursts or the tire air leaks. The elastomer 24 is preferably a solid tire. The advantages of a solid tire are wear resistance and puncture resistance. The solid tire ensures that after the tire 3 bursts or the tire air leaks, the solid tire reduces the overall distance between the wheel assembly and the ground, and the solid tire supports the effective contact between the tire 3 and the ground, realizing a smooth transition between the tire 3 and the solid tire, maintaining the balance of the vehicle, aircraft and other mobile devices using the tire, and enabling the vehicle, aircraft and other mobile devices using the tire to drive normally and safely.

[0038] On the basis of ensuring the reasonable tire pressure and gas storage capacity of the tire 3, the area of the explosion-proof tire assembly 2 is set to minimize the occupation of the internal space between the tire 3 and the rim 13.

[0039] Specific working process of the embodiment of the present utility model: First, assemble all the connecting blocks A 20 into the tire 3, then install the connecting block B 21 into the inner space of the tire 3 and assemble it with the connecting block A 20 to form a complete and fixed explosion-proof tire assembly 2. Then, install the explosion-proof tire assembly 2 and the tire 3 together on the rim B 132, and then align the stop structure 135 at the part of the rim A 131 in contact with the supporting component 22, fix and lock the entire explosion-proof tire assembly 2, and use bolts to fix the flanges 133 of the rim A 131 and the rim B 132 together to complete the assembly of the entire explosion-proof tire and the wheel assembly for preventing tire air leakage.

[0040] The normal working state is as follows: The wheel body 1 and the tire 3 support the outside of the tire 3 to contact the ground through a certain air pressure. The elastomer 24 of the explosion-proof tire assembly 2 is preferably a solid tire (note: all subsequent descriptions of the elastomer 24 will be based on the solid tire). There is a certain gap between the outer circumference of the solid tire and the inside of the tire 3, and the gap is set to ensure that after the tire 3 bursts or leaks air, vehicles, airplanes, and other mobile devices using the tire 3 will not lose balance. The solid tire reduces the overall distance between the wheel body 1 and the ground; vehicles, airplanes, and other mobile devices using the tire 3 travel normally under the support of the tire 3. When the tire 3 bursts or leaks air, the gravity of the vehicles, airplanes, and other mobile devices using the tire 3 causes the inner end of the tire 3 to quickly contact the outer end of the solid tire, and the solid tire quickly supports the tire 3 to contact the ground. The contact between the solid tire and the tire 3 realizes the balance and smooth transition of supporting the vehicles, airplanes, and other mobile devices using the tire 3. Since the contact surface between the outer end of the solid tire and the inner end of the tire 3 basically coincides, it prevents the vehicles, airplanes, and other mobile devices using the tire 3 from slipping due to the reduction of the friction between the solid tire and the tire 3 during driving after the tire 3 bursts or leaks air, maintaining the basic balance of the vehicles, airplanes, and other mobile devices using the tire 3, and at the same time enabling the vehicles, airplanes, and other mobile devices using the tire 3 to continue to drive normally and safely.

[0041] Finally, it should be noted that: The above is only a specific embodiment of the present utility model, and the embodiment is only used to illustrate the technical solution of the present utility model, rather than a limitation to other forms; although the present utility model has been described in detail with reference to the above embodiment, those of ordinary skill in the art should understand that they can still modify the technical solution recorded in the above embodiment, or perform equivalent substitution on some or even all of the technical features, and these modifications or substitutions do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the present utility model; the protection scope of the present utility model is not limited to this, and any equivalent transformation and modification based on the technical solution of the present utility model belong to the protection scope of the technical solution of the present utility model.
