Detailed ways

The present utility model will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, and cannot be used to limit the protection scope of the present invention.

Referring to Figures 1-2, a self-rescue device for automobile tire pits of the present invention includes a base 1 and an airbag cushion 2 fixed on one side of the base 1 . The airbag cushion 2 is provided with a perforation 21 in the middle of one side away from the base 1 , and a strap 22 for tying the airbag cushion 2 to the tire of the automobile is perforated in the perforation 21 . The base 1 is provided with a driving mechanism for inflating the airbag cushion 2 , and the driving mechanism includes a driving roller 3 , a power transmission rod 4 , and an air pump 5 . The driving roller 3 is rotatably arranged on the base 1, and its sidewall can abut on the tire of the automobile. The power transmission rod 4 and the air pump 5 are both built in the base 1 , the two ends of the power transmission rod 4 are hinged with the driving roller 3 and the air pump 5 respectively, and the air pump 5 is connected with the airbag cushion 2 . air valve connection.

Referring to Fig. 3, when the tire of the car falls into the mud pit, place the self-rescue device on one side of the mud pit, then bind the strap 22 to the tire of the car, and the tire rotates and drives the strap 22 to move along the mud pit to the side of the mud pit. On the other side, at this time, the airbag cushion 2 is covered in the mud pit (that is, the airbag cushion 2 is located between the tire of the car and the mud pit), and the driving roller 3 is abutted on the tire of the car; The belt 22 continues to drive the tires of the car to rotate. At this time, the driving roller 3 which is in contact with the tires of the car can rotate accordingly, and the power transmission rod 4 drives the air pump 5 to operate, and then inflates the airbag cushion 2, and the tires of the car are pushed upward.
