one end of a sliding block A306 is slidably mounted at one end of a bidirectional screw 305, a threaded hole is formed in the sliding block A306, the threaded hole is matched with threads of the bidirectional screw 305, the other end of the sliding block A306 is fixedly connected with one end of one of the folding connecting blocks 307, specifically, after the folding connecting blocks 307 are used, the folding connecting blocks 307 are picked up manually, the folding connecting blocks 307 are simply folded into a U shape, and occupied space of the folding connecting blocks 307 for a trunk can be reduced; the number of the folding connecting blocks 307 is multiple, the folding connecting blocks 307 are rotationally connected, the folding connecting blocks 307 are made of steel plates, and the steel structure is simple and convenient to manufacture, short in construction period, good in assembly performance, high in strength and good in toughness; one end of the sliding block B308 is slidably mounted at one end of the limiting rod 309, and the other end of the sliding block B308 is fixedly connected with one end of one of the folding connecting blocks 307; specifically, the sliding block a306 and the sliding block B308 move to drive the folding connecting block 307 to move, and the sliding block a306 disengages from the bidirectional screw 305, so that the folding connecting block 307 moves to the lower end of the wheel, and the wheel is convenient to leave a mud pit.

The working principle is as follows:

when a vehicle body part 1 is driven, wheels suddenly sink into a mud pit, the transverse moving mechanism 201 can drive the longitudinal moving mechanism 202 to move to the position of one wheel, then the servo electric cylinder A203 moves to enable the telescopic extending structure and the overturning folding structure to be in contact with the mud pit, and then the longitudinal moving mechanism 202 moves to drive the telescopic extending structure and the overturning folding structure to be inserted into the bottoms of the wheels in the mud pit;

the motor fixedly arranged on the telescopic folding plate A204 drives the hollow screw 211 to rotate, so as to drive the slide block on the hollow screw 211 to move, so as to drive the telescopic folding plate A204 to move, and further drive the telescopic folding plate B205 to drive the special-shaped telescopic plate 206 to move; the wheel is convenient to rotate and the automobile can walk by being inserted into the mud pit;

after the special-shaped expansion plate 206 and the rotating plate 213 are inserted into the mud pit, the motor fixedly mounted on the special-shaped expansion plate 206 drives the rotating plate 213 to rotate, so that the rotating plate 213 is turned down, and when the special-shaped expansion plate is used, wheels pass through the inside of the special-shaped expansion plate 206, so that an automobile leaves the mud pit;

meanwhile, a motor fixedly connected with the shaft of the sector gear A208 drives the sector gear A208 to rotate, and further drives the sector gear B209 to rotate, so as to drive a round rod on the side surface of the rotating folding plate 207 to move in a sliding groove of a semicircular sliding rail 210, and further drive the rotating folding plate 207 to turn over, so that the rotating folding plate 207 is folded back, the occupied space at ordinary times is reduced, the storage is convenient, meanwhile, sludge on two sides can be pulled open, and excessive sludge is prevented from entering the inside of the special-shaped expansion plate 206, so that the friction force of a convex block on one surface of the special-shaped expansion plate 206 is reduced;

after the special-shaped expansion plate 206 is inserted into the mud pit, the buckle on the connecting rod buckle 212 is rotated to be separated from the round rod below the servo electric cylinder A203, so that the telescopic extension structure and the turnover folding structure are left in the mud, and the automobile can conveniently leave; after the telescopic folding structure is used, the telescopic extending structure and the overturning folding structure can be taken back independently by manpower, so that the telescopic folding structure is convenient to use next time;

when two front wheels of the vehicle body part 1 are sunk into a mud pit, the front end of the vehicle body part 1 can be driven to leave the ground by the telescopic hydraulic cylinder 301 in a telescopic mode;

when the sliding support plate structure is used, the servo electric cylinder B302 and the servo electric cylinder C310 stretch and retract to drive the special-shaped support 314 and the square fixing block 313 to move, after the special-shaped support reaches a proper position, the servo motor 303 drives the cylindrical gear B312 to rotate, the cylindrical gear A304 is further driven to rotate, the bidirectional screw 305 is further driven to rotate, the sliding block A306 and the sliding block B308 move to drive the folding connecting block 307 to move towards wheels on two sides, after the sliding block A306 moves outwards to be separated from the bidirectional screw 305, the folding connecting block 307 just moves below the wheels and is placed on the ground, and then the front wheels of the automobile are placed on the folding connecting block 307 through the telescopic hydraulic cylinder 301, so that the wheels can conveniently leave a mud pit;

after using folding connecting block 307, pick up folding connecting block 307 through the manual work to simply fold folding connecting block 307 into the U type, can reduce folding connecting block 307 and to the occupation of land space of trunk, also can directly install the vehicle bottom, make things convenient for next use.
