Description

Technical Field

[0001] The invention relates to the technical field of tires, in particular to explosion-proof automobile tires. Background Art

[0002] Existing tires are almost all pneumatic tires. Although pneumatic tires have many advantages, they often have the risk of tire blowout, which is unpredictable. When pneumatic tires are running on off-road roads or roads with harsh working conditions, the carcass is easily damaged or punctured by foreign objects. Some tires use self-sealing technology and apply a layer of special sealant inside the tire. When the tire is punctured, the sealant can quickly fill the hole to prevent gas leakage, thereby improving the explosion-proof performance to a certain extent. However, when the tire is running for a long time, the tire temperature will increase. After the increase, the overall elasticity of the tire and the sealant layer will decrease, resulting in a decrease in the explosion-proof performance. Patent announcement number CN114393955B discloses a blow-proof tire and a preparation method thereof. Although it improves the explosion-proof performance of the tire from a structural perspective, if the tire temperature is too high, its explosion-proof performance will still be reduced.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figure 1-Figure 9 As shown, an embodiment of the present invention provides an explosion-proof automobile tire, comprising a wheel hub 200 and a tire body 100 arranged on the outside of the wheel hub 200, the inner wall of the tire body 100 is coated with a sealant layer 400, so that even if the sealant layer 400 is punctured, the air tightness can be maintained, and the problem of rapid air leakage leading to tire blowout will not occur, a connecting ring 205 is provided at the center position of the inner side of the wheel hub 200, a fixing sleeve 208 is provided on the connecting ring 205, a wheel axle 207 is rotatably provided on the fixing sleeve 208, and a convection heat dissipation component for taking away the internal heat of the tire body 100 is provided on the wheel hub 200, and the internal heat of the tire body 100 can be taken away in time through the convection heat dissipation component, so as to avoid the problem of high temperature of the tire body 100 and ensure the explosion-proof performance of the tire; The convection heat dissipation component includes an installation channel arranged in the wheel axle 207, a cache box 302 is arranged in the installation channel, the cache box 302 is connected to the inner wall of the wheel axle 207 through a positioning connecting rod, a one-way air intake pipe 301 for one-way air intake is arranged on the outside of the cache box 302, a filter is arranged at the port position of the wheel axle 207, a one-way exhaust pipe 310 for one-way exhaust is arranged on the inside of the cache box 302, the outer end of the one-way exhaust pipe 310 is communicated with the heat exchange disk box 313, a plurality of pressure storage and charging valves 318 are distributed on the outside of the heat exchange disk box 313, and a one-way delivery valve 318 is arranged on the pressure storage and charging valve 318. The air pipe 319, the outer end of the one-way air supply pipe 319 passes through the wheel hub 200 and extends to the inside of the tire body 100. The wheel hub 200 is also provided with a plurality of heat dissipation exhaust pipes 326 in an array. The heat dissipation exhaust pipe 326 is provided with a pressure-limiting exhaust valve. When the gas reaches a set value, the gas here will be discharged to avoid the problem of tire blowout caused by excessive air pressure. The cache box 302 is provided with an inflatable member for filling gas therein, and the inflatable member includes a gas compression cylinder 314 connected to the cache box 302. A gas piston plate 315 is slidably provided inside the gas compression cylinder 314. The gas piston plate 315 A gas piston rod 316 is provided at the upper end of the gas piston rod 316, and a gas pressure wheel 317 is rotatably provided at the outer side of the upper end of the gas piston rod 316. The reset block at the outer side of the gas piston rod 316 is connected to the top of the gas compression cylinder 314 through a gas reset spring. A heat dissipation trigger for generating a downward thrust on the gas pressure wheel 317 is provided on the wheel hub 200. When the internal temperature of the tire body 100 is higher than the set value, the heat dissipation trigger will start to work, so that the gas pressure wheel 317 generates a downward pressure, and the gas pressure wheel 317 will drive the gas piston plate 315 to move downward along the gas compression cylinder 314 through the gas piston rod 316. The tire 200 moves, thereby compressing the gas and sending the gas into the heat exchange disk box 313. When the gas pressure inside the heat exchange disk box 313 is higher than the set value, the gas will enter the tire body 100 along the pressure storage inflation valve 318 and the one-way air supply pipe 319, and then squeeze the hot air inside the tire body 100 out along the heat dissipation exhaust pipe 326, thereby completing convection heat dissipation and avoiding the problem of excessive tire temperature. The wheel hub 200 is provided with an air cooling unit for cooling the heat exchange disk box 313. The air cooling unit can accelerate the heat loss on the surface of the heat exchange disk box 313, thereby further reducing the temperature of the air entering the tire body 100. The air cooling unit includes heat dissipation fins arranged in an array on the outer surface of the heat exchange disk box 313, and a plurality of air inlet notches 204 are arranged in an array on the wheel hub 200. Each air inlet notch 204 is provided with an air inlet guide vane 206 for guiding the airflow to enter. The wheel hub 200 is provided with an air guide cone plate 320 for guiding the airflow to the surface of the heat exchange disk box 313, so that when the wheel hub 200 rotates, the air inlet guide vane 206 will also rotate together. Under the guidance of the air inlet guide vane 206, the outside air enters along the air inlet notch 204, and along the guidance of the air guide cone plate 320, the airflow will blow toward the heat exchange disk box 313, which accelerates the airflow outside the heat exchange disk box 313, so that the air heat dissipation speed is increased, and the compressed air inside the heat exchange disk box 313 will also be cooled down; The air cooling unit also includes a spraying member for spraying water mist onto the surface of the heat exchange disk box 313, the spraying member includes a liquid compression cylinder 304 fixedly connected to the outer side of the air guide cone plate 320, a liquid piston plate 305 is slidably provided in the liquid compression cylinder 304, a liquid piston rod 306 is fixedly provided at the outer end of the liquid piston plate 305, a liquid pressure wheel 307 is rotatably provided on the outer side of the end of the liquid piston rod 306, a reset block on the outer side of the liquid piston rod 306 is connected to the top of the liquid compression cylinder 304 through a liquid compression spring 308, the one-way liquid inlet of the liquid compression cylinder 304 is connected to the one-way water inlet pipe 303, the outer end of the one-way water inlet pipe 303 is connected to the water supply equipment through the end of the wheel axle 207, the one-way liquid discharge port of the liquid compression cylinder 304 is connected to the water spray ring 311 through the one-way liquid discharge pipe 309, and the water spray ring 311 is connected to the cache box 302 through the spray positioning rod. A plurality of atomizing nozzles 312 are distributed on the outside of the water spray ring 311. The water spray ring 311 is coaxially arranged with the heat exchanger box 313. The diameter of the liquid pressure wheel 307 is smaller than the diameter of the gas pressure wheel 317. In this way, when the inflatable part starts to work, the spray part will not be triggered. However, when the inflatable part cannot reduce the temperature of the tire body 100, the heat dissipation trigger part will further expand, thereby triggering the spray part. Under the push of the heat dissipation trigger part, the liquid pressure wheel 307 will drive the liquid piston plate 305 to move through the liquid piston rod 306. The liquid piston plate 305 will compress the liquid inside the liquid compression cylinder 304 into the water spray ring 311. The liquid in the water spray ring 311 is sprayed out along the atomizing nozzle 312. The sprayed water mist falls on the surface of the heat exchanger box 313. The evaporation of the water mist will absorb a large amount of heat, thereby further reducing the internal temperature of the heat exchanger box 313, thereby making up for the deficiency of single air cooling and heat dissipation. The heat dissipation trigger comprises an expansion piston cylinder 325 fixed on the wheel hub 200, the expansion piston cylinder 325 is filled with an expansion filler 323, such as mercury, an expansion piston plate 322 is slidably provided in the expansion piston cylinder 325, the outer end of the expansion piston plate 322 is connected to the conical trigger block 321 through a connecting rod, the connecting rod is slidably arranged with the guide hole at the end of the expansion piston cylinder 325, the conical trigger block 321 is a conical platform structure with a large inner end and a small outer end, the interior of the expansion piston cylinder 325 is connected to one end of the heat-conducting rod 324, and the other end of the heat-conducting rod 324 extends to the inside of the tire body 100, so that the high temperature inside the tire body 100 can be conducted to the inside of the expansion piston cylinder 325 In the initial state, that is, when the temperature inside the tire body 100 is lower than the set value, the conical trigger block 321 will not contact the gas pressure wheel 317. However, as the temperature inside the tire body 100 increases, the heat-conducting rod 324 will transfer heat to the expansion filler 323, so that the expansion filler 323 expands. The expanded expansion filler 323 generates thrust on the gas pressure wheel 317, so that the inflatable part works, and the gas continuously enters the heat exchange tray box 313 to inflate the heat exchange tray box 313. When the set pressure value is exceeded, the gas will enter the tire body 100 along the pressure storage inflation valve 318 and the one-way air supply pipe 319. The gas entering the tire body 100 squeezes out the hot gas therein, thereby completing the cooling operation. The exhaust pressure of the heat exchanger box 313 is greater than the exhaust pressure of the tire body 100, so that the gas entering the tire body 100 can be in an expanded state, and the expanded gas can do work externally, thereby reducing its own temperature, thereby optimizing the cooling effect, and even if there is a little air leakage in the ventilation method here, the ventilation method here can be used to replenish air in time. It should be noted that the pressure here is matched with the running of the tire and will not exceed the limit of the tire, so there is no need to worry about the problem of over-inflation; The filter element includes a baffle 327 disposed at the outer end of the axle 207, and a filter screen 328 for filtering the incoming air is disposed on the baffle 327. The filter screen 328 is detachable, so that the gas will be filtered when entering the axle 207, thereby reducing the problem of dust accumulation inside the device; An outer cover plate 201 is provided at the outer port position of the wheel hub 200. The outer cover plate 201 is connected to the wheel hub 200 via a plurality of connecting bolts 202. A plurality of grille holes 203 for exhaust are distributed on the outer cover plate 201, so that the exhaust position can be protected.

[0027] Working principle: In actual use, if a sharp object pierces the tire body 100, due to the presence of the sealant layer 400, the tire body 100 will not leak, ensuring that the tire can run normally. When the temperature inside the tire body 100 is too high, the heat dissipation trigger will start to work, so that the gas pressure wheel 317 will generate downward pressure. The gas pressure wheel 317 will drive the gas piston plate 315 to move downward along the gas compression cylinder 314 through the gas piston rod 316, thereby compressing the gas and sending the gas into the heat exchange disk box 313. When the gas pressure inside the heat exchange disk box 313 is higher than the set value, the gas will enter the tire body 100 along the pressure storage inflation valve 318 and the one-way air supply pipe 319, and then squeeze the hot air inside the tire body 100 out along the heat dissipation exhaust pipe 326, thereby completing convection heat dissipation. When the inflatable part is unable to lower the temperature of the tire body 100, the heat dissipation trigger part will further expand, thereby triggering the spray part. Driven by the heat dissipation trigger part, the liquid pressure wheel 307 will drive the liquid piston plate 305 to move through the liquid piston rod 306. The liquid piston plate 305 will compress the liquid inside the liquid compression cylinder 304 into the water spray ring 311. The liquid in the water spray ring 311 is sprayed along the atomizing nozzle 312. The sprayed water mist falls on the surface of the heat exchange disk box 313. The evaporation of the water mist will absorb a large amount of heat, thereby further reducing the internal temperature of the heat exchange disk box 313, thereby making up for the deficiency of air cooling alone.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
