[0043] The specific embodiment is as follows: When it is necessary to disassemble the wheel, remove the bolt 3 to separate the protective cover 2 from the hub 4, and then remove the wheel from the new energy vehicle. At this time, squeeze the moving plate 93 into the inside of the clamping block 61. The moving block 66 is squeezed into the inside of the clamping block 61 through the moving plate 93. When the moving block 66 is displaced, it will drive the sliding plate 62 to move through the connecting rod 65, thereby driving the triangular block 63 to move. At this time, the fixing rod 611 will drive the pulley 613 to slide in the travel groove 64. When the triangular block 63 moves, the clamping block 69 will descend under the limit of the telescopic rod 68. When the clamping block 69 disengages from the fixing groove 92, pull out the embedding rod 91 from the clamping block 61, so as to separate the hub 4 from the rim 5, and then remove the tire 1 for replacement.

[0044] The clamping component 9 includes an embedding rod 91 and a moving plate 93. A fixing groove 92 is provided on the upper surface of the embedding rod 91. An opening is provided on the side wall of the embedding rod 91. One end of the moving plate 93 extends outside the other side wall of the embedding rod 91. A baffle 94 is fixedly installed on the outer surface of the moving plate 93. A compression spring 95 is fixedly installed on the side wall of the baffle 94. One end of the compression spring 95 is fixedly connected to the inner wall of the embedding rod 91. The moving plate 93 passes through the compression spring 95.

[0045] The specific embodiment is as follows: The rim 5 is passed through the interior of the tire 1, and then after aligning the insertion rod 91 on the side wall of the wheel hub 4 with the insertion groove 610 on the side wall of the clamping block 61, the insertion rod 91 is inserted into the groove. At this time, the snap block 69 will be clamped into the fixing groove 92 on the surface of the insertion rod 91, thereby connecting the wheel hub 4 and the rim 5.

[0046] The inflation assembly 8 includes a placement box 81. An air outlet 82 is provided on the outer wall of the placement box 81. A soft cover 84 is fixedly installed on the upper surface of the placement box 81. A reaction mechanism 83 is provided on the inner wall of the bottom surface of the placement box 81. The lower surface of the placement box 81 is fixedly connected to the outer surface of the rim 5. An auxiliary tire 7 is fixedly installed on the outer surface of the rim 5. The reaction mechanism 83 includes a reaction box 831. The lower surface of the reaction box 831 is fixedly connected to the inner wall of the bottom surface of the placement box 81. A pointed cone 832 is fixedly installed on the inner wall of the bottom surface of the reaction box 831. Calcium carbide powder is provided inside the reaction box 831. An exhaust valve 835 is fixedly installed on the upper surface of the reaction box 831. One end of the exhaust valve 835 extends into the reaction box 831. A pressing rod 837 is fixedly installed on the lower surface of the soft cover 84. One end of the pressing rod 837 extends into the reaction box 831. A lower pressing plate 834 is fixedly installed at one end of the pressing rod 837. A water bag 833 is fixedly installed on the lower surface of the lower pressing plate 834. Vent holes 836 are provided on the upper surface of the lower pressing plate 834.

[0047] The specific embodiment is as follows: When the tire leaks air, the auxiliary tire 7 on the outer surface of the rim 5 can still support the vehicle to travel a certain distance. At the same time, when the rim 5 rotates, the placement box 81 will also rotate. When the soft cover 84 is squeezed by the ground, it will drive the lower pressing plate 834 to descend through the pressing rod 837. At this time, the lower pressing plate 834 will drive the water bag 833 to move downward, causing the water bag 833 to come into contact with the pointed cone 832. At this time, the water bag 833 will be punctured by the pointed cone 832, causing the water inside to flow out and mix with the calcium carbide in the reaction box 831. When the two are mixed, a large amount of non-dangerous gas will be generated rapidly. The generated gas will flow out through the vent holes 836, and then through the exhaust valve 835, the gas will flow into the placement box 81 and be ejected from the air outlet 82 on the outer surface of the placement box 81, thereby filling the tire 1 with a certain amount of gas and reducing the damage to the rim 5 and the auxiliary tire 7 of the new energy vehicle.

[0048] The heat dissipation assembly 10 includes a turntable 101. The turntable 101 is rotatably connected to the inner wall of the protective cover 2. A rotating rod 102 is fixedly installed on the side wall of the turntable 101. A wind attracting plate 103 is fixedly installed on the outer wall of the rotating rod 102. A fan blade 104 is fixedly installed at one end of the rotating rod 102.

[0049] Specific embodiments thereof are as follows: During the driving of a new energy vehicle, wind enters between the wheel hub 4 and the protective cover 2 through the ventilation holes on the protective cover 2, and then blows out through the ventilation holes. During the flow of the wind, the wind-catching plate 103 will be blown by the wind, so that the rotating rod 102 rotates to drive the fan blade 104 to start rotating. At this time, the wind generated by the fan blade 104 will have a certain heat dissipation effect on the brake pads.

[0050] Working principle: Pass the rim 5 through the inside of the tire 1, and then align the insertion rod 91 on the side wall of the wheel hub 4 with the insertion groove 610 on the side wall of the clamping block 61, and insert the insertion rod 91 into the groove. At this time, the snap block 69 will be stuck in the fixing groove 92 on the surface of the insertion rod 91, so as to connect the wheel hub 4 and the rim 5. Then, after fixing the assembled wheel to the axle of the vehicle, use the bolt 3 to fixedly connect the protective cover 2 to the other side wall of the wheel hub 4. During the driving of the new energy vehicle, wind enters between the wheel hub 4 and the protective cover 2 through the ventilation holes on the protective cover 2, and then blows out through the ventilation holes. During the flow of the wind, the wind-catching plate 103 will be blown by the wind, so that the rotating rod 102 rotates to drive the fan blade 104 to start rotating. At this time, the wind generated by the fan blade 104 will have a certain heat dissipation effect on the brake pads. During the driving of the new energy vehicle, when the tire leaks air, the auxiliary tire 7 on the outer surface of the rim 5 can still support the vehicle to drive for a certain distance. At the same time, when the rim 5 rotates, the placement box 81 will also rotate. When the soft cover 84 is squeezed by the ground, it will drive the lower pressing plate 834 to descend through the lower pressing rod 837. At this time, the lower pressing plate 834 will drive the water bag 833 to move downward, so that the water bag 833 contacts the tapered body 832. At this time, the water bag 833 will be punctured by the tapered body 832, and the water inside will flow out and mix with the calcium carbide in the reaction box 831. When the two are mixed, a large amount of non-hazardous gas will be quickly generated. The generated gas will flow out through the ventilation hole 836, and then enter the placement box 81 through the exhaust valve 835 and spray out from the air outlet 82 on the outer surface of the placement box 81, so that the tire 1 is filled with a certain amount of gas, reducing the damage of the new energy vehicle to the rim 5 and the auxiliary tire 7. When the wheel needs to be disassembled, remove the bolt 3 to separate the protective cover 2 from the wheel hub 4, and then remove the wheel from the new energy vehicle. At this time, squeeze the moving plate 93 into the inside of the clamping block 61, and squeeze the moving block 66 into the inside of the clamping block 61 through the moving plate 93. When the moving block 66 moves, it will drive the sliding plate 62 to move through the connecting rod 65, so as to drive the triangular block 63 to move. At this time, the fixing rod 611 will drive the pulley 613 to slide in the travel groove 64. When the triangular block 63 moves, the snap block 69 will descend under the limit of the telescopic rod 68. When the snap block 69 disengages from the fixing groove 92, pull out the insertion rod 91 from the clamping block 61, so as to separate the wheel hub 4 from the rim 5, and then remove the tire 1 and replace it.
