[0048] When the anti-skid device is loaded, the driving motor 61 works to drive the driving bevel gear 64 to rotate, and the driving bevel gear 64 meshes with the driven bevel gear 40 to drive the driven bevel gear 40 to rotate. The driven bevel gear 40 drives the driving shaft 414 to rotate, and the driving shaft 414 drives the first helical gear 4151 to rotate, and the first helical gear 4151 meshes with the second helical gear 4152 to drive the driven shaft 416 to rotate.

The guide columns 4411 are in sliding fit with the guide grooves 4421, and the connecting plate 442 is connected with the moving block 441 by limiting screw 445 passing through the stepped limiting hole 4422. The length of the stepped limiting hole 4422 is the buffer distance of the anti-skid plate 446.

[0051] It should be noted that the sliding shaft 443 and the buffer spring 444 provide buffer for the anti-skid plate assembly 44 when moving to the circumferential surface of the wheel assembly 3, improve the stability of the movement, and prolong the service life of the anti-skid plate assembly 44.

The fixed plate is rotated clockwise to make the positioning block 8 in the small-end hole diameter (i.e. the limit position) of the sliding groove 201 to form an interference fit. Then, the fixed pin 76 and the positioning pin hole 202 form a hole shaft fit to complete the fixing of the anti-skid assembly 1 and the fixed plate assembly 2.

After the clamping screw 24 is locked, the clamping plate 23 and the wedge-shaped sliding block 26 are in close contact to realize the complete fixing of the fixed plate assembly 2 and the wheel assembly 3.

[0058] Next, the assembly method of the vehicle-mounted anti-skid device provided by the application will be further described.

[0059] When the vehicle-mounted anti-skid device is installed, the fixed plate assembly 2 is pushed into the wheel assembly 3 in the axial direction, and the wedge-shaped sliding block 26 is pre-fixed by the cooperation of the sliding block buckle 262 and the hub buckle 31 under the action of the sliding block spring 28 through the limiting of the fixed column 21 and the wedge-shaped sliding block 26, and then the locking set screw 24 is tightened to make the tight plate 23 tightly contact with the wedge-shaped sliding block 261, so as to realize the fixation of the fixed plate assembly 2 and the wheel assembly 3. The anti-skid assembly 1 is attached to the fixed plate 20 to make the positioning block 8 cooperate with the sliding groove 201, and after rotating the anti-skid assembly 1 to make the positioning block 8 reach the limit position, the fixing pin 76 passes through the positioning pin hole 202, so that the anti-skid assembly 1 and the fixed plate assembly 2 are fixed.

[0060] When the anti-skid device needs to be maintained, the fixing pin 76 is pulled out of the positioning pin hole 202, and then the anti-skid assembly 1 is counterclockwise rotated to make the positioning block 8 exit the positioning pin hole 202, so that the anti-skid assembly 1 can be removed. After the locking set screw 24 is loosened, the tight plate 23 is separated from the wedge-shaped sliding block 26 under the action of the tight spring 29, and the wedge-shaped sliding block 26 can slide in the fixed sleeve 25 to separate the cooperation with the hub buckle 31, so that the fixed plate assembly 2 can be removed in the axial direction.

[0061] Next, the working process of the vehicle-mounted anti-skid device provided by the application is further described:

The driven shaft 416 drives the rocker 46 to rotate in the limiting groove 481 in the limiting plate 48 in the clockwise direction, the rocker 46 drives the transmission rod 45 to rotate, so that the transmission rod 45 drives the anti-skid plate assembly 44 to move to the circumferential surface of the wheel assembly 3 and tightly contact with the circumferential surface of the wheel assembly 3 to realize anti-skid. The reinforcing ribs 4461 and the anti-skid nails 447 provided on the anti-skid plate 446 can increase the friction between the tire surface and the ground, and improve the driving safety.

[0063] When the vehicle anti-skid device is unloaded, the driving motor 61 reversely rotates, the driving bevel gear 64 reversely rotates, the driving bevel gear 64 meshes with the driven bevel gear 40, and drives the driven bevel gear 40 to rotate. The driven bevel gear 40 drives the driving shaft 414 to rotate, the driving shaft 414 drives the first helical gear 4151 to rotate, the first helical gear 4151 meshes with the second helical gear 4152, and drives the driven shaft 416 to rotate. The driven shaft 416 drives the rocker 46 to rotate in the limiting slot 481 in the limiting plate 48 in the counterclockwise direction, the rocker 46 drives the transmission rod 45 to rotate, so that the transmission rod 45 drives the anti-skid plate assembly 44 to separate from the tire surface and move to the bowl-shaped structure formed by splicing the outer shell of the anti-skid device 1. When the anti-skid plate 446 moves to the initial position, the driving motor 61 stops working.
