When the vehicle needs to be locked, the rotating hub 3 is decelerated under the driving of the driving piece 32 to rotate, the matching block 41 moves towards one side close to the locking hole 61 under the guiding of the spiral guiding groove 31 until the matching block 41 enters the corresponding limiting groove 33, and the lock tongue 4 extends outwards and is inserted into the locking hole 61 at the moment, so that the locking of the steering column is realized. At this time, even if an abnormal person applies a reverse mechanical force to the latch tongue 4 to try to disengage the latch tongue 4 from the lock groove, the engagement piece 41 is stably positioned in the limit groove 33 by the limit action of the limit groove 33, so that the latch tongue 4 is held at a position effectively locked with the lock hole 61, and the effective locking of the steering column is ensured.

In some possible implementations, referring to fig. 2 and 3, the peripheral wall of the decelerating rotating hub 3 is provided with two magnetic members 51 respectively disposed near two ends of the spiral guiding groove 31, and in the axial direction of the decelerating rotating hub 3, the two magnetic members 51 are respectively disposed at two sides of the spiral guiding groove 31;

The guide surface 45 has an inclination angle with respect to the main axis of the reduction hub 3, which is designed to be smaller than the friction angle. When there is torque in the steering column, the guide surface 45 causes the locked tongue 4 to receive a component force toward the lock hole 61, and therefore, the angle also satisfies the self-locking condition. At the same time, the angle is set so that the component force of the locked tongue 4 toward the lock hole 61 is much smaller than the frictional force that would be applied when the tongue 4 is pulled out without providing the guide surface 45, and therefore, even when there is a large torque in the steering column, the unlocking can be smoothly performed by driving the small-torque driving element 32.

The transmission mode of the worm wheel 35 and the worm 34 is adopted, so that the stability of power transmission is ensured, and the stability of locking or unlocking action is improved.

The use process comprises the following steps:

when the vehicle needs to be locked, the rotating hub 3 is decelerated under the driving of the driving piece 32 to rotate, the matching block 41 moves towards one side close to the locking hole 61 under the guiding of the spiral guiding groove 31 until the matching block 41 enters the corresponding limiting groove 33, and the lock tongue 4 extends outwards and is inserted into the locking hole 61 at the moment, so that the locking of the steering column is realized. At this time, even if an abnormal person applies a reverse mechanical force to the latch tongue 4 to try to disengage the latch tongue 4 from the lock groove, the engagement piece 41 is stably positioned in the limit groove 33 by the limit action of the limit groove 33, so that the latch tongue 4 is held at a position effectively locked with the lock hole 61, and the effective locking of the steering column is ensured.

If the locking hole 61 and the locking tongue 4 are not aligned correctly and correct locking is not completed, the engaging piece 41 will be stopped at the middle position of the spiral guiding groove 31, and locking cannot be completed smoothly. At this moment, the magnetic member 51 cannot smoothly reach the target position, the sensor 52 can timely detect the position information of the magnetic member 51 and transmit the position information to the vehicle body control system through the circuit board 53 to remind a driver of the unlocked condition of the vehicle, meanwhile, the control system judges and controls the driving member 32 to rotate reversely according to a preset program so that the bolt 4 moves towards the direction of releasing the locking, and after the unlocking is completed, the driver waits for the release of the next locking command.
