The automobile antiskid chain is an automobile safety article specially designed for automobile driving safety. The special rough surface of the antiskid chain is utilized to increase the friction force between the antiskid chain and the road surface, so that the antiskid chain plays a role in protecting the wheel assembly, preventing the wheel assembly from slipping and ensuring the normal running of the vehicle under the condition of snow and muddy road generally. Especially on the road surface with accumulated snow in winter, the running stability and the driving safety of the vehicle can be effectively ensured.
The principle of the antiskid chain is that the gravity of a vehicle is concentrated on a plurality of points of the chain to generate huge pressure, and the vehicle can roll through an ice and snow layer to reach the road surface, so that the friction force is increased, and the safety factor of the vehicle in running is increased. When snow is no longer present, the snow chain should be removed. In any case, the chain cannot be carried on a road surface without snow, which can seriously damage the wheel assembly and increase the wear of the anti-skid chain.
The mounting of snow chains, although not very cumbersome, has the drawback of being able to be used only on snow (or mud) covered roads, and not on clean ground, which would damage the wheel assemblies and aggravate the wear of the snow chains. However, in winter, after heavy snow, the difference between the sunny side and the shady side of the road surface always causes the phenomenon that one section has snow and the other section has no snow, so that the antiskid chain is frequently mounted (or dismounted) during parking, too much time is wasted, traffic jam can be caused if a road section with a large traffic flow is encountered, and the vehicle can be parked only if a proper place is found on an expressway.
In a word, the antiskid chain is simple to install and disassemble at one time, but is troublesome after being installed and disassembled at multiple times.

In addition, the self-loading/unloading snow chain of the embodiment further comprises an electric control element for individually controlling the driving device of each snow chain mechanism 3. And a gravity sensor and a sensor are arranged in each anti-skid chain mechanism 3 and are electrically connected with the electric control element. The sensor is used for detecting the working condition of the driving device and feeding back a normal signal to a driver after the driving device finishes working or feeding back an abnormal signal to the driver when the driving device works abnormally. The gravity sensor is used for judging the height of the anti-skid chain mechanism 3 according to the gravity direction, and when the gravity direction of the anti-skid chain mechanism points to the axis line of the mounting seat, the anti-skid chain mechanism moves to the highest position; when the gravity direction of the antiskid chain mechanism points to the opposite direction of the axis of the mounting seat, the antiskid chain moves to the lowest position.

After the electronic control unit receives the detachment signal, the driving device in the chain mechanism 3 that has moved to the highest position is sequentially controlled, so that the corresponding chain 32 is detached from the outer circle of the wheel assembly 1 and is accommodated back into the accommodating groove 313 of the bracket 31, and before the chain mechanism 3 moves to the lowest position, the driving device needs to complete the work. And completing the disassembly of all the anti-skid chains 32 until the wheel assembly 1 rotates for one circle.
Specifically, the lifting driving device 33 drives the bracket 31 to move away from the mounting seat 2, and the sliding driving device 34 drives the sliding block 315 to slide towards the wheel assembly 1, after moving to the preset position, the lifting driving device 33 tightens the bracket 31 towards the mounting seat 2, and the sliding driving device 34 tightens the anti-skid chain 32 towards the mounting seat 2, so that the anti-skid chain 32 can be installed on the outer circle of the wheel assembly 1 through the hook 321. Then, the bending driving device 35 pulls the bending section 312 of the bracket 31 to bend the bracket 31 toward the mounting base 2, and the sliding rail 314 is prevented from being damaged by rubbing a large stone when the automobile runs by tightening the bending section 312 inwards. At this time, since the elevating driving unit 33 pulls the bracket 31 downward and the snow chain 32 is caught on the outer circumference of the wheel assembly 1, the tension unit 316 is extended to protrude the snow chain 32 from the receiving groove 313, thereby preventing the sliding rail 314 from directly contacting the ground.
Conversely, the snow chain 32 can be removed from the outer circumference of the wheel assembly 1 and stored back into the storage groove 313 of the bracket 31.
