Description

car anti-skid wheel

technical field

The utility model relates to an anti-skid wheel of an automobile, which belongs to the technical field of automobile safety.

Background technique

At present, automobiles provide great convenience for human travel and delivery of goods, but once encountering rainy and snowy weather, slippery roads and thick snow have caused great safety hazards to driving safety. In real life, people usually install anti-skid chains or anti-skid studs on the wheels to increase the friction of the car tires, but when the car is driving on a snow-free road, the anti-skid chains or anti-skid studs will hinder the driving of the car, so the anti-skid chains must be removed Or anti-skid studs, when encountering ice and snow again, stop to install anti-skid chains or anti-skid studs, this frequent installation and disassembly is very loaded down with trivial details, wastes time, and takes physical strength very much. In addition, people will also use claw-type anti-skid devices. These anti-skid devices are mostly rigidly connected, and the claws are easy to bend, which will damage the wheels and cause potential safety hazards.

Anti-skid wheels (201010181804.8) provide a solution for automobile anti-skid, but it requires the car to deflate the tire properly before driving on the icy and snowy road, so that the anti-skid steel can protrude from the tire. The anti-skid section steel is trapped in the tire; although this method solves the problem of anti-skid driving of the car on wet and slippery roads such as ice and snow, it is very cumbersome to repeatedly inflate and deflate. The anti-skid method of automobile driving in winter and the inflatable external anti-skid wheels used (201210034361.9) also have the cumbersome operation of repeatedly charging and deflating the external anti-skid wheels.

An anti-skid device for motor vehicle wheels (201320009346.6) Although the friction force of the wheels is increased, the contact area between the protruding anti-skid spikes and the ground is too small, and the anti-skid effect is not good. It not only hinders the driving of the car, but also causes certain damage to the road surface, which needs to be disassembled, which brings tedious and time-consuming repeated installation and disassembly. The cat claw-shaped telescopic anti-skid wheel for automobiles (201220395895.X) also has the problem that the contact area with the ground is too small and the anti-skid effect is not good.

Contents of the invention

The purpose of the utility model is to provide an anti-skid wheel for automobiles, which solves the problems that the existing anti-skid device needs to be repeatedly installed and disassembled and the anti-skid effect is not ideal in the application process.

The utility model is realized according to the following technical solutions: an anti-skid wheel for automobiles, comprising a tire 1, a wheel frame 2, an inner magnet holder 3, an outer magnet holder 4, an anti-skid mechanism, a spring 6, a screw 7, an outer magnet 8, and an inner magnet 9. Battery 10, limit slider 11, end cover 12; the inner magnet holder 3 is installed on the wheel frame 2, the inner magnet 9 is installed on the inner magnet holder 3 through interference fit, and the outer magnet holder 4 passes through the gap Fittingly installed outside the inner magnet holder 3, the outer magnet 8 is installed on the outer magnet holder 4 through the screw 7, and the battery 10 is installed on the wheel frame 2 to provide current for the inner magnet 9, so that the inner magnet 9 generates a magnetic field, and the end cover 12 Installed on the outside of the wheel frame 2, the tire 1 is installed on the outside of the wheel frame 2, the wheel frame 2 is provided with anti-skid claw slideway II16, and the tire 1 is provided with anti-skid claw slideway I15, and the anti-skid mechanism is installed on the outer magnet holder 4. The middle part of the frame 2 is provided with an axle mounting hole 17 .

Described anti-skid mechanism comprises anti-slip claw 5, spring 6, limit slide block 11; The limit slide block 11 is provided with chute 14, is equipped with slide rail 13 on the anti-skid claw 5, slide rail 13 on the anti-slip claw 5 and The chute 14 of the limit slider 11 is matched, and the anti-slip claw 5 is connected with the limit slider 11 through the cooperation of the spring 6 and the slide rail 14 with the chute 15, and the anti-slip mechanism is installed on the outer magnet holder 4 through the limit slider 11 , the anti-slip claw 5 is provided with a flexible hook I18, and the outer magnet holder 4 is provided with a flexible hook II19. In the anti-skid claw slideway II16 of the wheel frame 2 , the anti-skid claw slideway I15 of the tire 1 corresponds to the position of the anti-skid claw slideway II16 of the wheel frame 2 .

The working principle of an anti-skid wheel for an automobile is as follows: when the automobile is running on a normal road, the direction of the magnetic poles of the inner magnet 9 is changed by the direction of the current flowing into the inner magnet 9, and the outer magnet holder 4 has a strong magnetic force between the inner magnet 9 and the outer magnet 8. Under the action of the inner magnet 9, it is fixed on one side of the inner magnet 9. At this time, the flexible hook I18 on the anti-skid claw 5 can be hooked with the flexible hook II19 on the outer magnet holder 4; , change the direction of the current flowing into the inner magnet 9, so that the outer magnet holder 4 is fixed on the other side of the inner magnet 9 under the action of a strong magnetic force between the inner magnet 9 and the outer magnet 8. At this time, the flexibility on the anti-slip claw 5 The hook I18 can be separated from the flexible hook II19 on the outer magnet holder 4, and the anti-slip claw 5 protrudes along the anti-slip claw slideway I15 and the anti-slip claw slideway II16 under the action of the thrust of the spring 6, and the anti-slip claw 5 contacts and rubs against the ground , which increases the coefficient of friction, which can effectively avoid skidding; when the car drives on the normal road again, the direction of the current flowing into the inner magnet 9 is changed, so that the outer magnet holder 4 has a strong magnetic force between the inner magnet 9 and the outer magnet 8 At this time, the anti-skid mechanism moves inward along the radial direction of the wheel under the force of the ground, and the flexible hook II19 on the outer magnet holder 4 contacts the flexible hook I18 on the anti-skid claw 5. Under the action of the contact force, the hook body of the flexible hook I18 on the anti-slip claw 5 bends, and after the anti-slip mechanism moves for a certain distance, the flexible hook I18 on the anti-slip claw 5 can hook with the flexible hook II19 on the outer magnet holder 4 , now the anti-skid pawl 5 will not be contacted with the ground, and will be trapped in the tire 1. After the wheel travels for a week, all the anti-skid pawls 5 will be trapped in the tire 1.

The utility model has the following beneficial effects:

1. The device controls the extension and retraction of the anti-skid claws through the current of the inner magnet, and can quickly open the anti-skid mode;

2. The operation is simple, and repeated disassembly can be avoided, and the work efficiency is high;

3. The contact area with the ground is large, the anti-skid effect is good, and the application range is wide.
