For example, in the example of fig. 1, 2 and 4, the steering column 1 is provided with the steering device 32, and the steering device 32 and the steering wheel telescopic and steering motor device 4 may be engaged with each other or separated from each other. When the steering device 32 is matched with the steering wheel telescopic and steering motor device 4, the steering device 32 is driven by the steering wheel telescopic and steering motor device 4 to rotate, and the steering column 1 is driven by the steering device 32 to start rotating. Thus, with the above arrangement, when the vehicle 200 needs to turn, the steering device 32 and the steering wheel can be made to extend and contract to cooperate with the steering motor device 4, so that the steering column 1 can be rotated to provide power assistance for the steering of the vehicle 200. When the steering wheel 21 needs to be stretched or the vehicle 200 needs to run straight, the steering device 32 and the steering wheel stretching and steering motor device 4 can be separated, so that the steering column 1 stops rotating, the structure is simple, and the operation is convenient.

When the steering column connecting wheel 321 is matched with the steering wheel extension and retraction and steering motor device 4, the steering wheel extension and retraction and steering motor device 4 drives the steering column connecting wheel 321 to rotate, because the circumferential limiting piece 322 limits the circumferential rotation of the steering column connecting wheel 321 relative to the steering column 1, the steering column 1 can synchronously rotate with the steering column connecting wheel 321, therefore, the circumferential limiting piece 322 is arranged between the steering column connecting wheel 321 and the steering column 1, the steering column 1 can rotate when the steering column connecting wheel 321 is matched with the steering wheel extension and retraction and steering motor device 4, and power assistance is provided for the steering of the vehicle 200.

Therefore, under the driving of the telescopic steering wheel and the steering motor 41, the driving part 42 can drive the driven wheel 43 to rotate, so that the telescopic rod 2 can move up and down or the steering column 1 can rotate, the structure is simple, and the transmission efficiency is high.

In some alternative embodiments of the present invention, as shown in fig. 1, 3 and 4, the driving member 42 is a worm, and the driven wheel 43 is a worm wheel engaged with the worm.

When the worm wheel is matched with the steering wheel telescopic device 31, the steering wheel telescopic and steering motor 41 can output small torque and drive the telescopic rod 2 to move up and down; when the worm gear is engaged with the steering device 32, the steering wheel extension and retraction and steering motor 41 can output a large torque, thereby providing power steering to the steering wheel 21 or actively steering the steering wheel 21. Therefore, the transmission efficiency between the steering wheel stretching and retracting and steering motor 41 and the steering wheel stretching and retracting and steering device 3 is greatly improved.

For example, as shown in fig. 4, in the manual driving mode, the left clutch 5 is engaged and the right clutch 5 is disengaged, and at this time, the driven wheel 43 is engaged with the steering wheel retracting device 31, and the steering wheel retracting and steering motor 41 drives the driving member 42 to rotate the driven wheel 43 together, so that the steering wheel retracting wheel 311 rotates and drives the retractable rod 2 to move up and down, and the steering wheel 21 automatically extends. In the automatic driving mode, the left clutch 5 is disengaged and the right clutch 5 is engaged, at this time, the driven wheel 43 is matched with the steering device 32, the steering wheel extension and retraction and steering motor 41 receives the rotation angle and rotation speed instruction in the automatic driving mode and drives the driving part 42 to drive the driven wheel 43 to rotate together, and the steering column connecting wheel 321 is driven by the driven wheel 43 to rotate, so that the automatic steering function is realized. Similarly, in the manual driving mode, the left clutch 5 is engaged and the right clutch 5 is disengaged, the steering wheel extension and retraction and steering motor 41 drives the steering wheel extension wheel 311 to rotate, so that the steering wheel 21 automatically extends out, after the steering wheel 21 extends out to a proper position, the left clutch 5 is disengaged and the right clutch 5 is engaged, the steering wheel extension and retraction and steering motor 41 inputs a torque signal through the vehicle speed and the steering wheel 21, the output torque of the motor is controlled, so that the steering column connecting wheel 321 is driven to rotate, and the auxiliary steering function is realized. Therefore, by arranging the clutches 5 between the driven wheel 43 and the steering wheel retracting device 31 and between the driven wheel 43 and the steering device 32, the steering wheel 21 can be automatically retracted and hidden in the automatic driving mode, the steering wheel retracting and steering motor 41 can provide active steering power, the steering wheel 21 can be automatically extended in the manual driving mode, and the steering wheel retracting and steering motor 41 can perform auxiliary power steering of the steering wheel 21.

That is, the lower end of the telescopic rod 2 may be provided with the limiting member 22, the inner wall of the concave hole 11 of the steering column 1 may be provided with the limiting hole 111, or the inner wall of the concave hole 11 of the steering column 1 may be provided with the limiting member 22, and the lower end of the telescopic rod 2 may be provided with the limiting hole 111. Therefore, the telescopic rod 2 is limited to rotate relative to the steering column 1 in the circumferential direction, the telescopic rod 2 can only move axially relative to the steering column 1, and the steering column device is simple in structure and convenient to machine.

Further, referring to fig. 2, the stopper 22 is provided on the outer peripheral wall of the bottom end of the telescopic rod 2, and the stopper hole 111 penetrates the end face of the top end of the steering column 1. Therefore, the limiting piece 22 is matched with the limiting hole 111, the circumferential rotation of the telescopic rod 2 relative to the steering column 1 is limited, the telescopic rod 2 can move up and down along the axial direction of the steering column 1, and the distance that the telescopic rod 2 can move freely is longer because the limiting hole 111 penetrates through the top end face of the steering column 1.
