DETAILED DESCRIPTION

[0023] The steering column assembly with a special shape in the adjustment area includes a support frame 1, a column 2, a locking mechanism 8, a rotating assembly 5, a locking pin 9, a limiting hole 11 and a limiting sliding pin 12 (see the attached manual). Figure 1 , 2 and 3).

[0024] A pipe column 2 is arranged in the support frame 1; when the pipe column 2 is pressed by the locking mechanism 8, it can be compressed and fixed.

[0025] The two sides of the pipe column 2 are fixed with assembly plates 3; the bottom end of the support frame 1 is equipped with a rotating assembly 5 through a locking nut 4 (see the attached manual). Fig. 9 and 10 ).

[0026] The rotating assembly 5 includes a support screw 15, a sleeve 17, a locking washer 16 and a sliding sleeve 18; one end of the support screw 15 passes through the support frame 1 and is threadedly connected to a locking nut 4; a locking washer 16 is sleeved on the support screw 15 between the locking nut 4 and the support frame 1; a sleeve 17 is sleeved on the support screw 15 inside the support frame 1; sliding sleeves 18 are installed at both ends of the sleeve 17; the sliding sleeve 18 is slidably connected to the lower transverse sliding hole 6 on the corresponding assembly plate 3 (see the attached manual Fig.10 ).

[0027] The purpose of setting the rotating assembly 5 in this way is: first, to keep the support screw 15 fixedly connected with the support frame 1 under the action of the locking flat washer 16 and the sliding sleeve 18; second, to keep the assembly plate 3 slidingly connected with the rotating assembly 5 through the lower transverse sliding hole 6.

[0028] The upper end of the support frame 1 is provided with a locking pin 9 through a vertical sliding hole 7 and a locking mechanism 8; the locking mechanism 8 is of conventional design, and when working, the support frame 1 can be pressed or loosened to lock or loosen the pipe column 2 by rotating its own handle.

[0029] The locking pin 9 is slidably connected with the upper transverse sliding hole 10 provided on the assembly plate 3 (see the appendix of the specification). Figure 5 and 6). A force-saving spring A13 is mounted on the locking pin 9; one end of the force-saving spring A13 is connected to the front end of the support frame 1. A force-saving spring B14 is mounted on the rear end of the assembly plate 3; one end of the force-saving spring B14 is connected to the support frame 1 (see the attached manual). Figure 4 The purpose of setting the force-saving spring A13 and the force-saving spring B14 is to make the force-saving spring A13 always have the tendency to pull the pipe column 2 upward, so that when the inclination angle of the steering wheel is adjusted by the pipe column 2, the elastic force of the force-saving spring A13 can offset part of the gravity, thereby achieving the purpose of saving effort.

[0030] A limit hole 11 is provided on the support frame 1 on one side of the assembly plate 3; a limit slide pin 12 is fixedly installed on the assembly plate 3 inside the limit hole 11; the limit slide pin 12 is intermittently connected with the limit hole 11 (see the attached manual). Figure 7 The purpose of setting the limiting slide pin 12 and the limiting hole 11 is to make it possible for the column 2 to be adjusted within the range limited by the limiting hole 11 under the action of the limiting slide pin 12 when the locking mechanism 8 is released and the steering wheel position is adjusted by moving the column 2. In this way, the purpose of controlling the adjustment area can be achieved through the limiting hole 11, thereby achieving the purpose of making the adjustment area irregular (see the attached manual). Figure 8 ) to better meet the driver's needs for adjustment and use.

[0031] The steering column assembly with a special-shaped adjustment area can be limited to a special-shaped structure by the limiting sliding pin 12 and the limiting hole 11 when working, thereby solving the problem that the adjustment area of ​​the existing steering column assembly is rectangular, and is particularly suitable for the needs of automobile steering systems.
