The friction plate 10 is sleeved on the adjusting screw 5 and surrounds the bushing 506, and the inner side of the plane bearing 504 is abutted against the outer side of the clamping plate 9. The clamping plate 9 is provided with a through hole having the same shape as the rectangular through hole 601, and the adjusting screw 5 can move in the through hole along the length direction of the through hole. When the steering column adjusting mechanism is in a locked state, the nut 503 axially and inwardly extrudes the plane bearing 504, so that the pressing plate 9 compresses the friction plate 10, the holding force of the steering column adjusting mechanism is improved, and the steering column adjusting mechanism is prevented from being loosened due to vibration generated by a vehicle; when the steering column adjustment mechanism is in a relaxed state, the pressure of the pressure plate 9 against the friction plate 10 is reduced, providing less resistance to the steering column adjusting the angle of inclination, so as to adjust the position of the steering column.

In some embodiments of the present application, as shown in fig. 2 to 3, the upper tubular column 1 may include a pair of guide blocks 12, the pair of guide blocks 12 are respectively connected to the cylindrical portion of the upper tubular column 1, and two inner sidewalls of the adjusting bracket 6 respectively abut against outer sidewalls of the pair of guide blocks 12, a rectangular guide hole 1202 is formed in each of the pair of guide blocks 12, the adjusting screw 5 passes through the guide hole 1202 and is capable of moving in the guide hole 1202 along a length direction of the rectangular guide hole 1202, and a width of the rectangular guide hole 1202 is equal to a diameter of the adjusting screw 5 to limit an adjusting direction of the steering column.

It should be noted that the longitudinal direction of the guide hole 1202 is parallel to the axial direction of the upper pipe column 1, and the depth direction of the guide hole 1202 is parallel to the axial direction of the adjustment screw 5. When the upper pipe column 1 is axially displaced relative to the lower pipe column 2, the adjusting screw 5 can move in the guide hole 1202 relative to the upper pipe column 1, and the length of the rectangular guide hole 1202 is the axial displacement of the upper pipe column 1.

As shown in fig. 8, a wear-resistant material is disposed around the guide hole 1202, and a buffer block 1201 is disposed at a narrow rectangular edge of the guide hole 1202. In the process of adjusting the position of the steering column, the adjusting screw 5 is closely attached to the hole wall of the guide hole 1202, and friction occurs between the adjusting screw and the hole wall of the guide hole 1202. This may wear the adjusting screw 5 and the guide hole 1202 and make an abnormal sound, which may affect the use experience of the driver. And the wear-resistant material is arranged in the guide hole 1202 in a surrounding mode, so that the abrasion of the adjusting screw rod 5 and the hole wall of the guide hole 1202 can be reduced, abnormal sound generated in the adjusting process is avoided, when the steering column is adjusted to the limit position, the buffer block 1201 can buffer the impact from the adjusting screw rod 5, and the use experience of the steering column adjusting mechanism is improved.

When the handle 4 is rotated to enable the locking block 1103 to be screwed out of the groove of the handle 4, the inclined arc surface of the locking block 1103 is abutted against the edge of the groove of the handle 4, so that the locking block 1103 is extruded out of the groove, the distance between the handle 4 and the adjusting bracket 6 is increased, and the adjusting bracket 6 is pressed to lock the upper pipe column 1; the top surface of the limiting block 1104 is connected with the adjusting part 1102 through a vertical plane, so that the limiting block 1104 is prevented from being screwed out of the groove of the handle 4, and the handle 4 and the cam block 11 are prevented from falling off.

When the position of the steering wheel is adjusted on the vehicle, the handle 4 can be rotated firstly, so that the locking block 1103 enters the groove on the handle 4, the steering column adjusting mechanism is in a loose state, then the steering wheel is pulled out or pushed in to axially adjust the position of the upper column 1, and meanwhile, the steering column can be pushed back and forth, so that the adjusting screw rod 5 moves in the guide hole 1202 to adjust the inclination angle of the steering column. After the adjustment is completed, the handle 4 can be rotated back in the opposite direction, so that the edge of the groove on the handle 4 extrudes the inclined arc surface of the locking block 1103, the locking block 1103 is moved out of the groove on the handle 4, and the adjusting bracket 6 is pressed tightly and the position of the steering column is fixed.

To sum up, in the steering column adjustment mechanism that this application embodiment provided, only be provided with one cam block 11, twist grip 4 can make the latch segment 1103 on the cam block 11 can the recess on the hand grip 4 of immigration to make steering column adjustment mechanism be in laxity state, so that adjust steering column's angle and position, adjust the back, twist grip 4 to the opposite direction, in order to shift out the recess on the hand grip 4 with latch segment 1103, thereby compress tightly the position of adjusting bracket 6 and fixed steering column. The cam block 11 and the handle 4 are simple in matching structure and have higher stability. And need not to set up two crisscross cam pieces of each other, the whole space that has occupied of mechanism has avoided the vehicle to travel or adjust the in-process of steering column to appear abnormal sound, improves and drives experience. The nut 503, the plane bearing 504 and the adjusting spring 505 can automatically adjust the gap between the components axially arranged on the adjusting screw 5, without arranging a plurality of friction plates, and have larger locking force, and the looseness is not easy to occur in the running process of the vehicle.

The first spring 7 and the second spring 8 referred to in the present application are extension springs, and the adjustment spring 505 referred to is a compression spring. The material of the wear-resistant material surrounding the guide hole 1202 and the material of the buffer block 1201 referred to in this application may be plastic, and the material of the bushing 506 may also be plastic.

In this application, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. The term "plurality" means two or more unless expressly limited otherwise.

Although the present invention has been described with reference to the above embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
