Problems solved by technology

[0004] The above-mentioned invention can improve the axial force of the steering column. However, its disadvantage is that only the structure of the gear plate and the tooth block is relatively simple. The tendency to move, the first tooth and the second tooth bear a large force, and they are prone to damage after a long time of use, resulting in a decrease in the axial force of the steering column

Embodiment 1

[0032] Such as Figure 1-5 As shown, the steering column includes a lower tube body 1, a fixed bracket 2 and an upper tube body 3 slidingly connected with the lower tube body 1, the upper tube body 3 is fixed with a snap-fitting part 4, and the fixed bracket 2 is fixed with a clip Fitting two 5, the upper tube body 3 is connected with a strip bar 6, and the strip bar 6 passes through the snap fitting one 4 and the snap fitting two 5 at the same time, and one end of the strip bar 6 is provided with a The third 7 of the engaging piece 4 and the second 5 of the engaging piece are engaged. The bar bar 6 can be a bolt, and the engaging part 3 7 can be fixed on one end of the bolt by threaded connection, and a nut 30 is threaded on the bolt.

[0033] Such as image 3 , 4 As shown, the engaging part 2 5 includes a strip plate 2 28, the edge of the strip plate 2 28 has teeth 3 8, the engaging part 3 7 has a boss 2 9, and the boss 2 9 has a Three 8-phase engaged teeth four 10. Tee...

Embodiment 2

[0043] The structure and principle of this embodiment are basically the same as that of Embodiment 1, the difference is that the positioning mechanism 17 includes a snap ring and a boss 3 21 fixed on the left end of the bar 6, when the engaging part 4 and the engaging After the two pieces 5 are engaged and fixed with the fastening piece three 7, a snap ring is sleeved on the strip bar 6, so that one end of the snap ring leans against the fixed plate one 15, and the other end of the snap ring leans against the boss Three 21, so that the three are not easy to separate, increase the stability of the connection between the upper pipe body 3 and the fixed bracket 2.

Abstract

The invention provides an automobile steering column and belongs to the technical field of automobiles. The technical problem that the axial force of an existing automobile steering column is likely to be reduced when an automobile collision happens is solved. The steering column comprises a lower pipe body, a fixing support and an upper pipe body connected with the lower pipe body in a sliding manner. A first clamping piece is fixed to the upper pipe body. A second clamping piece is fixed to the fixing support. A bar-shaped rod is connected to the upper pipe body and penetrates the first clamping piece and the second clamping piece at the same time. A third clamping piece capable of being clamped with the first clamping piece and the second clamping piece at the same time is arranged at one end portion of the bar-shaped rod. By the adoption of the automobile steering column, the connection stability of the fixing support and an upper pipe column can be improved, and the stable axial force of the automobile steering column is kept for a long time.

Description

technical field [0001] The invention belongs to the technical field of automobiles and relates to an automobile steering column. Background technique [0002] When a car collides violently, the driver tends to lean forward due to the sudden stop of the car, and the chest of the human body will collide with the steering wheel. Large impact force, in order to reduce the impact force, some cars design the steering column as a structure that can collapse during impact, so as to buffer the impact force. For the steering mechanism of different cars, the design of the crush point is also different. In the design of the collapse point of the steering column, one is set on the steering column, that is, the inner steering column and the outer steering column are riveted through interference fit, and the collapse is realized under the action of external force; the other is Installed on the mounting bracket, the mounting bracket and the steering column are welded into one body. Under ...
