The steering column mainly has the function of transmitting the rotating torque of a steering wheel to a steering gear so as to perform steering operation of an automobile, and in the practical application process, one end of a mandrel 30 is connected with the steering wheel, and the other end of the mandrel is connected with the steering gear; in the embodiment of the present invention, the end of the spindle 30 exposed outside the second barrel 20 is connected to the steering wheel, the end of the spindle 30 exposed outside the first barrel 10 is connected to the steering gear, and the spindle 30 is engaged with the first barrel 10 and the second barrel 20 through bearings, so that the spindle 30 can rotate conveniently.
In order to adjust the height of the steering wheel, generally, the core shaft 30 is composed of two sections, and specifically may include a first shaft and a second shaft, which are telescopically connected by a spline, and when the second frame tube 20 moves along the axial direction of the first frame tube 10, the first shaft and the second shaft may be driven to perform telescopic motion, so as to achieve the purpose of adjusting the height of the steering wheel.
Specifically, referring to fig. 2 to 4, a first through groove 16 is axially disposed on the first barrel 10, a first inlet 17 and a first outlet 18 are respectively disposed at two ends of the first through groove 16, the cross section of the first barrel 10 is polygonal, and a first axial opening is disposed on one side surface of the first barrel 10 in the length direction. I.e. the three-sided opening of the first barrel 10, preferably, the cross section of the first barrel 10 is octagonal, the two ends of the first barrel 10 are respectively provided with the first inlet 17 and the first outlet 18, and one of the sides of the first barrel 10 constituting the octagonal shape is vacant in the length direction, thereby constituting the first axial opening. The octagonal first frame cylinder 10 is close to a round shape, so that torque transmission can be well performed, meanwhile, the octagonal first frame cylinder 10 can be processed by adopting a thinner plate, and compared with the prior art that a thicker pipe needs to be processed into a round pipe shape, the lightweight level is improved; in addition, the first axial opening is provided in the longitudinal direction of the first barrel 10, which further reduces the weight of the first barrel 10.
Referring to fig. 1, the cross section of the second barrel 20 is also polygonal; a second through groove is axially formed in the second frame cylinder 20, and a second inlet and a second outlet are respectively formed in two ends of the second through groove; the end of the second barrel 20 provided with the second outlet is inserted into the through groove from the first inlet 17, and the second barrel 20 can move in the through groove along the axial direction of the first barrel 10, and two ends of the mandrel 30 are respectively exposed outside the second inlet and the first outlet 18. This structure reduces the overall weight while achieving the height adjustment of the steering wheel by the cooperation of the second barrel 20 and the first barrel 10.
The second frame tube 20 needs to be inserted into the first frame tube 10 and moved in the first frame tube 10, and thus the shape of the cross section of the second frame tube 20 is also preferably octagonal. Similarly, the second barrel 20 can be formed by processing a thin plate material, and thus the weight of the second barrel 20 as a whole can be greatly reduced.
Referring to fig. 2, it can be seen that one end of the adjusting bracket 40 is rotatably connected to one end of the first barrel 10 having the first outlet 18; the other end of the adjusting bracket 40 is connected to the end of the first barrel 10 having the first inlet 17 through an angle adjusting mechanism 50. The adjusting bracket 40 is shaped like a rectangular parallelepiped frame, so that the adjusting bracket 40 can be formed by machining a thin plate, thereby further reducing the weight of the steering column assembly.

When the pitch angle of the steering wheel needs to be adjusted, the adjusting bracket 40 and the first frame tube 10 are loosened by operating the tightening handle 52, then the pitch angle of the first frame tube 10 is adjusted by taking the rotary joint of the adjusting bracket 40 and the first frame tube 10 as a rotary point, and the first frame tube 10 can drive the mandrel 30 to adjust the angle, so that the purpose of adjusting the pitch angle of the steering wheel is finally achieved. After the adjustment is completed, the tightening handle 52 is tightened again to fix the first casing 10 and the adjusting bracket 40.
When the pitch angle is adjusted, a return spring 60 can be arranged to assist the adjustment, so that the adjustment speed can be increased in one adjustment direction. Specifically, the first extension plates 13 may be provided on both sides of the first axial opening of the first barrel 10, and the second extension plates 43 may be provided on both sides of the second axial opening of the adjusting bracket 40; the return spring 60 has one end connected to the first extension plate 13 and the other end connected to the second extension plate 43.
