[0027] 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.

[0028] See also Figure 1-Figure 6 , a tire rescue device, comprising:

[0029] A bonding sheet 1, wherein the bonding sheet 1 is bonded to the wheel hub, the bonding sheet 1 is provided with screw holes adapted to the screw holes of the wheel hub, a tire is provided on the outside of the wheel hub, the bonding sheet 1 is connected to the wheel hub by bolts, and the bonding sheet 1 is provided in a plurality of groups evenly arranged;

[0030] When using the tire rescue device, first fit the bonding sheet 1 to the wheel hub. The bonding sheet 1 has toughness and certain strength. It can be made of three-layer thickened material and textured fabric, so it will not deviate when used and can be placed more stably, ensuring that the bonding sheet 1 fits tightly to the side wall of the wheel hub. Then, tighten the bolts to stably connect the bonding sheet 1 to the wheel hub to prevent loosening during use. In this way, the bonding sheet 1 firmly mounts the rescue device on the wheel hub;

[0031] A support component, the support component includes an airbag 2 and an air valve 3, the airbag 2 is annular, the inner wall of the airbag 2 is connected to the outer wall of the bonding sheet 1, a thickening layer 4 is provided at one end of the airbag 2 away from the bonding sheet 1, and the air valve 3 is provided at one side of the airbag 2 away from the wheel hub;

[0032] After the rescue device is installed, the airbag 2 is inflated through the air valve 3. As the airbag 2 is inflated, the airbag 2 expands in a ring shape. Since the inner wall of the airbag 2 is connected to the outer wall of the bonding sheet 1, it will gradually stand up. The thickened layer 4 of the airbag 2 gradually contacts the ground, providing additional support for the vehicle, reducing the degree to which the tire sinks into the ground, and the rounding provides buffer protection. Several groups of friction patterns 5 set in the thickened layer 4 increase the friction with the ground. When the vehicle starts, it can effectively prevent the tire from slipping and help the vehicle get out of trouble on soft roads such as mud, sand or snow;

[0033] The outer diameter of the airbag 2 is larger than the outer diameter of the tire only as a preferred example of this embodiment. In actual use, there is no restriction on the size of the airbag 2, as long as it can stably support the tire and help the vehicle get out of trouble;

[0034] At the same time, due to the supporting effect of the airbag 2 with the thickened layer 4, the vehicle can avoid bottoming out when moving back and forth in the pit, thus ensuring the vehicle's safe escape;

[0035] After expansion, the airbag 2 with the thickened layer 4 can stably support the vehicle. The airbag 2 can also be connected to the tire with the wheel strap 7 to further ensure its fit with the tire, and then provide good support for the vehicle. After the vehicle is out of trouble, it can be selected whether to use it again according to the damage of the device;

[0036] In this embodiment, three groups of evenly arranged bolts are used to lock the fitting sheet 1 and the wheel hub. In actual use, a limiting member is also provided on the airbag 2, and the limiting member is arranged on the peripheral side of the air valve 3. The limiting member includes a back sheet 6 and a strap 7. The back sheet 6 is fitted with the airbag 2, and a strap 7 is arranged on the front of the back sheet 6. An air pump 8 is arranged between the back sheet 6 and the strap 7, and the strap 7 is connected to the back sheet 6 by Velcro. According to needs, the air pump 8 can be selected to connect the air valve 3. The air pump can be conveniently limited by the limiting member, and the air pump 8 can be stably supported, thereby ensuring the convenience of equipment use. The position of the limiting member is not limited to being installed on the airbag 2, and can also be located on the fitting sheet 1, or only the air pump 8 can be used to inflate the airbag 2.

[0037] In this embodiment, the airbag 2 is also provided with an exhaust switch 9 to ensure high efficiency during deflation.
