Problems solved by technology

[0004] However, the fractured plastic pin and the steering column will fall downward, causing the steering column to separate from the driver, causing the energy absorption of the steering column to suddenly drop to zero. This sudden change will cause the steering column to be unstable. absorb energy

Embodiment Construction

[0039] In order to make the purpose, technical solution and advantages of the present disclosure clearer, the implementation manners of the present disclosure will be further described in detail below in conjunction with the accompanying drawings.

[0040] figure 1 is a schematic structural diagram of a steering column provided by an embodiment of the present disclosure, as shown in figure 1 As shown, the steering column includes a column body 1 and a clamping assembly 2 .

[0041] figure 2 yes figure 1 The three-dimensional structural schematic diagram of another angle of the steering column shown. Such as figure 2 As shown, the column body 1 includes a steering shaft 11 for connecting the steering wheel, an upper column 12 and a lower column 13 for connecting with the instrument beam. The first end of the upper column 12 is sleeved on the first end of the lower column 13. On the end, the two ends of the steering shaft 11 are rotatably inserted in the upper pipe column...

Abstract

The invention provides a steering column, and belongs to the technical field of steering columns. The steering column comprises a column body and a clamping assembly, wherein the column body comprisesa steering shaft, an upper column and a lower column; the first end of the upper column is arranged on the first end of the lower column in a sleeving manner; the two ends of the steering shaft are rotatably inserted into the upper column and the lower column respectively; a strip-shaped notch is formed in the side wall of the upper column; the strip-shaped notch extends from the end part of thefirst end of the upper column to the middle part of the upper column along the axial direction of the upper column; limiting teeth are arranged on the inner wall of the middle of the strip-shaped notch; a pin is arranged on the peripheral wall of the lower column, inserted into the strip-shaped notch and located at the first end of the upper column; the pin makes contact with the inner wall of thestrip-shaped notch; two clamping plates are arranged on the peripheral wall of the upper column; and the clamping assembly is configured to clamp the two clamping plates. The steering column providedby the invention can stably absorb part of impact energy in secondary collision of a driver.

Description

technical field [0001] The present disclosure belongs to the technical field of steering column, and in particular relates to a steering column. Background technique [0002] With the rapid development of automobile technology, safety regulations have higher and higher requirements for automobile safety. Most of the existing automobile steering columns have energy-absorbing structures. When the front of the vehicle is hit violently, the driver will collide with the steering wheel due to inertia. It is used to absorb part of the impact energy in the secondary collision, so as to protect the driver to a certain extent. [0003] In related technologies, the collapse energy-absorbing structure of the steering column adopts an injection pin-pull-off block structure, that is, the injection pin is used to connect the pull-off block to the upper bracket of the steering column, and the pull-off block is fixedly connected to the crossbeam of the instrument panel. When a collision oc...
