Firstly, the main air bin 3 and the auxiliary air bin 4 are communicated through the vent holes 202 formed in the fixing piece 201, so that air pressure between the main air bin 3 and the auxiliary air bin 4 forms dynamic balance, and road noise is reduced.

Secondly, through the slider 203 that sets up in the air vent 202, and be connected slider 203 with stopper 204, because the connecting rod 205 bottom of connecting slider 203 with stopper 204 is equipped with the spring, when the spring does not receive the pressure from main air chamber 3 and vice air chamber 4, connecting rod 205 is located the connecting groove middle part, a plurality of sliders 203 in the air vent contact each other this moment, and cut apart main air chamber 3 with vice air chamber 4, make main air chamber 3 convert into two independent air chambers with vice air chamber 4, through the main air chamber 3 to the extrusion of vice air chamber 4 effectively improve the toughness of tire body 110, make tire body 110 have shock-resistant ability.

Thirdly, when the device is inflated and installed, gas is injected into the main air chamber 3, when the main air chamber 3 is filled with gas, the gas continuously enters the main air chamber 3, so that the pressure in the main air chamber 3 is greater than the pressure in the auxiliary air chamber 4, the pressures on the two sides of the sliding block 203 are different, the sliding block 203 is pushed by the gas in the main air chamber 3 to push the limiting block 204 to move downwards, the spring is extruded at the same time, because the limiting block 204 is movably connected with the telescopic bracket 208, the bottom ends of the telescopic brackets 208 on the two sides are far away from each other, when the limiting block 204 slides downwards on the telescopic bracket 208, the sliding block 203 is driven to move towards the two sides and contact the sealing limit of the vent hole 202, at the moment, the main air chamber 3 is communicated with the auxiliary air chamber 4 through the vent hole 202 to inflate the auxiliary air chamber 4, when the pressures in the auxiliary air chamber 4 and the main air chamber 3 are balanced again, the pushing block 203 is restored to the initial position under the elasticity of the spring, make and form two independent gas storehouses again between vice gas storehouse 4 and the main gas storehouse 3, simultaneously through the inflation of vice gas storehouse 4 with main gas storehouse 3, explosion-proof pad body 115 follows tire body 110 and falls into in the rim of steel ring 5 automatically, make the inside steel wire body 114 of packing ring 112 with the firm fixed of rim, fix explosion-proof pad body 115 on the rim firmly, play the sealed air effect simultaneously, can accomplish the installation simplification operating procedure to explosion-proof pad body 115, the operating personnel of being convenient for changes the installation to the tire.

Finally, as shown in the fifth drawing, if the tire body 110 suddenly breaks during the driving of the vehicle, the auxiliary air chamber 4 is communicated with the outside through the gap, and meanwhile, due to the extrusion of the gravity of the vehicle on the auxiliary air chamber 4, the gas in the auxiliary air chamber 4 quickly runs off, so that the explosion-proof cushion body 115 is in contact with the tire body 110, the gravity of the vehicle enables the explosion-proof cushion body 115 to be extruded, at this time, the extrusion block 209 arranged on the explosion-proof cushion body 115 is extruded by the explosion-proof cushion body 115 to extend into the movable groove 206, and pushes one end of the telescopic bracket 208 far away from the vent hole 202 to move towards the vent hole 202, because the position of the sliding block 203 is not changed at this time, the telescopic bracket 208 deflects by taking the limit block 204 as a fulcrum and contracts, so that the telescopic bracket 208 near one end of the vent hole 202 moves towards the direction far away from the vent hole 202, thereby changing the limit direction of the telescopic bracket 208 to the limit block 204, at this moment, the vehicle continues to run, the main air chamber 3 is extruded by the anti-explosion pad body 115 under the gravity of the vehicle, the air pressure in the main air chamber 3 increases and pushes the sliding block 203 to move downwards, because the sliding block 203 is in sealing connection with the air groove 202 in the state, and meanwhile, the sliding block 203 is limited by the limit block 204 through the telescopic bracket 208, so that the sliding block 203 cannot move downwards, the tire body 110 is effectively supported through the independent and sealed main air chamber 3, the fracture opening is firmly blocked by utilizing the characteristic of the anti-explosion pad body 115, the stability of the structure is increased, the working experience of workers is improved, after the automobile tire is prevented from being fractured, the dangerous condition caused by the fact that the vehicle cannot normally run is avoided, and the potential safety hazard of the vehicle is reduced.

In summary, the following steps: through the arrangement of the connecting assembly 2, the main air bin 3 and the auxiliary air bin 4, after the tire body 110 is broken, due to the extrusion of the gravity of the vehicle to the auxiliary air bin 4, the gas in the auxiliary air bin 4 is rapidly lost, the gravity of the vehicle extrudes the explosion-proof cushion body 115, the extrusion block 209 is extruded by the explosion-proof cushion body 115 to extend into the movable groove 206 and push one end of the telescopic bracket 208 far away from the vent hole 202 to move towards the vent hole 202, the telescopic bracket 208 deflects by taking the limit block 204 as a fulcrum and contracts, so that the telescopic bracket 208 near one end of the vent hole 202 moves towards the direction far away from the vent hole 202, thereby changing the limit direction of the telescopic bracket 208 to the limit block 204, the slide block 203 cannot move downwards due to the limit of the telescopic bracket 208 to the limit block 204, the tire body 110 is effectively supported by the independent closed main air bin 3, and the breakage of the automobile tire is prevented, the dangerous condition that the vehicle can not normally travel leads to has reduced the potential safety hazard of vehicle.

When a worker uses the device main body 1, firstly, the gasket 112 is installed in the annular groove 111, a gap is formed between the anti-explosion cushion body 115 and the tire body 110 to form the auxiliary air chamber 4, then the auxiliary air chamber 4 is communicated with the main air chamber 3 in the tire body 110 through the connecting component 2, then the main air chamber 3 is inflated by the worker, simultaneously, the anti-explosion cushion body 115 automatically falls into a rim of the steel rim 5 along with the tire body 110, the steel wire body 114 in the gasket 112 firmly fixes the rim, the anti-explosion cushion body 115 is firmly fixed on the rim, and simultaneously, the sealing air effect is achieved, the installation of the anti-explosion cushion body 115 can be completed, when the tire body 110 is suddenly broken in the driving process, the sealing effect of the tire body 110 is lost, the air pressure balance condition of the main air chamber 3 and the auxiliary air chamber 4 disappears, and the air in the auxiliary air chamber 4 between the anti-explosion cushion body 115 and the tire body 110 is exhausted, meanwhile, the main air chamber 3 acts on the explosion-proof pad body 115 to generate pressure difference, so that the explosion-proof pad body 115 is tightly attached to the inner wall of the tire body 110, the crack of the tire body 110 is firmly blocked, and the severity of the tire body 110 after cracking is greatly reduced.

Example two

In the actual use process, a driver finds that when an automobile runs on a pothole road section or the tire body 110 extrudes or collides with a road surface step in the running process of the automobile, due to a high-speed running state of the automobile, the contact position of the tire body 110 and the road surface step is greatly deformed, so that the steel wire body 114 positioned in the tire body 110 is broken, the broken position of the steel wire body 114 loses the protection of the tire body 114 in long-time running and overcharging, tire burst often occurs at the broken position, and a safety accident occurs.
