[0030] In this embodiment, under normal conditions, the tire pad 1 and the tie rod 7 are flipped into a parallel state to reduce the volume and facilitate storage on the vehicle. When in use, the tire pad 1 and the tie rod 7 are relatively flipped through the rotating shaft 3 until the limit stop angle 5 blocks the bottom surface of the tire pad 1, preventing the angle between the tire pad 1 and the tie rod 7 from continuing to increase, so that the angle between the two is close to an acute angle of a right angle. When in use, two screws for fixing the automobile wheel hub are unscrewed, and the remaining screws are retained to fix the wheel hub on the brake disc, and the bottom surface of the tire pad 1 is fitted to the outer diameter of the tire that needs to increase the grip, and the support spacer sleeve 16 is aligned with the position of the wheel hub screw hole where the screw is unscrewed, and then the fixing screw 15 is passed through the support spacer sleeve 16 and the wheel hub screw hole from the strip groove 14 in turn, and finally screwed into the fastening screw hole on the brake disc. At this time, the support spacer sleeve 16 One end of the strip plate 13 abuts against the automobile wheel hub, and the other end abuts against the strip plate 13. Under the pulling force of the fixing screw 15, the strip plate 13 is fastened to the automobile wheel hub to complete the preliminary locking. Then the adjusting slider 9 slides along the pull rod 7 until the bent hook 11 hooks the notch of the inner diameter of the wheel hub, and then the position of the adjusting slider 9 on the pull rod 7 is locked by screwing the set screw 10 into the tooth groove 8, so that the bent hook 11 can be tightly hooked with the inner notch of the wheel hub to complete further locking. At this time, the tire pad 1 is fastened to the side of the automobile tire through the strip plate 13 and the bent hook 11. When the automobile tire rotates, the protruding tire pad 1 provides additional grip to help the car get out of trouble. The set screw 10 adopts a countersunk hexagonal screw, and the fixing screw 15 adopts an external hexagonal screw or a hexagonal screw.

[0031] Specifically, the tire pad 1 includes a load-bearing plate layer 101 , the top surface of the load-bearing plate layer 101 is fixedly connected with an adhesive layer 102 , the top surface of the adhesive layer 102 is fixedly connected with a wear-resistant layer 103 , and the surface of the wear-resistant layer 103 is provided with a wave pattern 104 .

[0032] In this embodiment, the load-bearing plate layer 101 receives the driving force transmitted by the automobile tires through two axle seats 2, a rotating shaft 3 and two hinge blocks 4, as well as the local stress generated by pressing the tire pad 1 with the two hinge blocks 4 through the limit stop angle 5. The wear-resistant layer 103 is in contact with the ground, and the wavy pattern 104 is used to increase the contact area and grip of the rainy ground. The adhesive layer 102 is used to connect the load-bearing plate layer 101 and the wear-resistant layer 103 as a whole. At this time, the load-bearing plate layer 101 transmits the power from the automobile tires to the wear-resistant layer 103 and the wavy pattern 104, thereby increasing the friction with the ground and helping the vehicle's tires to get out of trouble.

[0033] Specifically, both sides of the tire pad 1 are rotatably connected with shaft rollers 105 through bearing frames, a crawler track 106 is wound around the two shaft rollers 105, and the automobile tire is pressed onto the crawler track 106.

[0034] In this embodiment, both sides of the tire pad 1 are rotatably connected to the shaft roller 105 through the bearing frame, and the track 106 is wound around the two shaft rollers 105. The car tire is pressed against the track 106, which is equivalent to putting on a shoe with good slip resistance for the car tire. When the car tire slips and idles on the ground with a small friction coefficient, the car tire can be pressed against the track 106 to transfer the driving force to the track 106, and then the track 106 can increase the contact area and friction on the ground with small friction, so as to drive the car to continue driving.

[0035] Specifically, the load-bearing plate layer 101, the bonding layer 102 and the wear-resistant layer 103 are mutually superimposed arc surface structures or semicircular groove structures.

[0036] In this embodiment, when the load-bearing plate layer 101, the adhesive layer 102 and the wear-resistant layer 103 are mutually overlapping arc surface structures, the arc surface structure can be adapted to the outer cylindrical surface of the automobile tire, thereby reducing the resistance when the automobile is getting out of trouble; when the load-bearing plate layer 101, the adhesive layer 102 and the wear-resistant layer 103 are mutually overlapping arc surface structures, half of the automobile tire can be directly and tightly embraced through the load-bearing plate layer 101, so that the tire pad 1 can rotate together with the automobile tire, thereby achieving rapid escape from trouble.

[0037] Specifically, the load-bearing plate layer 101 is made of stainless steel or high manganese steel, the adhesive layer 102 is made of double-sided adhesive board, and the wear-resistant layer 103 is made of rubber or engineering plastic.

[0038] In this embodiment, the load-bearing plate layer 101 is made of stainless steel or high-manganese steel, and has good structural strength and hardness, so that it will not deform when subjected to the pressure of the limit stop angle 5, thereby ensuring the flipping angle of the tire pad 1 and the pull rod 7. The bonding layer 102 is made of double-sided adhesive board material, which can simultaneously bond the load-bearing plate layer 101 and the wear-resistant layer 103 and provide a buffering force between the two. The wear-resistant layer 103 is made of rubber or engineering plastic material, and has the characteristics of soft texture and strong wear resistance. Therefore, it can follow the car tire for a long time to rotate and assist until the car is out of trouble and the rescue is successful.

[0039] Specifically, the wear-resistant layer 103 is screwed to the load-bearing plate layer 101 by connecting screws.

[0040] In this embodiment, the wear-resistant layer 103 is screwed to the load-bearing plate layer 101 by connecting screws. The connecting screws fasten the wear-resistant layer 103 and the load-bearing plate layer 101 together, so that the load-bearing plate layer 101 can transmit the power for escape to the wear-resistant layer 103, and the wear-resistant layer 103 can realize the escape force on the soft bottom surface.

[0041] Specifically, a rubber sleeve is nested and fixed on the bent hook 11 .

[0042] In this embodiment, a rubber sleeve is nested and fixed on the bent hook 11 to protect the stress-bearing surface of the automobile wheel hub and prevent the stress-bearing surface of the automobile wheel hub from being deformed or scratched.

[0043] Specifically, a rescue warning sign is embedded and connected to the bottom end of the strip groove 14.

[0044] In this embodiment, a rescue warning sign is embedded at the bottom end of the strip groove 14. When the user takes the main structure of the present invention to rescue the vehicle, the rescue warning sign can be taken out from the strip groove 14 and placed around the vehicle to warn other vehicles to avoid or provide corresponding rescue assistance.

[0045] In this embodiment, the set screw 10 and the fixing screw 15 are known technologies that have been disclosed and widely used in industrial production and daily life.

[0046] The working principle and use process of the present invention are as follows: Under normal conditions, the tire pad 1 and the tie rod 7 are flipped into a parallel state to reduce the volume and facilitate storage on the vehicle. When in use, the tire pad 1 and the tie rod 7 are relatively flipped through the rotating shaft 3 until the limit stop angle 5 blocks the bottom surface of the tire pad 1, preventing the angle between the tire pad 1 and the tie rod 7 from continuing to increase, so that the angle between the two is close to an acute angle of a right angle. When in use, two screws for fixing the automobile wheel hub are unscrewed, and the remaining screws are retained to fix the wheel hub on the brake disc. The bottom surface of the tire pad 1 is fitted to the outer diameter of the tire that needs to increase the grip, the support spacer sleeve 16 is aligned with the position of the wheel hub screw hole where the screw is unscrewed, and then the fixing screw 15 is passed through the support spacer sleeve 16 and the wheel hub screw hole from the strip groove 14 in sequence, and finally the screw is screwed in. The strip plate 13 is tightened and connected to the wheel hub of the automobile under the pulling force of the fixing screw 15, and the initial locking is completed. Then the adjusting slider 9 is slid along the pull rod 7 until the bent hook 11 hooks the groove of the inner diameter of the wheel hub, and then the position of the adjusting slider 9 on the pull rod 7 is locked by screwing the set screw 10 into the tooth groove 8, so that the bent hook 11 can be tightly hooked with the inner groove of the wheel hub to complete further locking. At this time, the tire pad 1 is tightly connected to the side of the automobile tire through the strip plate 13 and the bent hook 11. When the automobile tire rotates, the protruding tire pad 1 provides additional grip to help the car get out of trouble.
