Embodiment Construction

[0022] Such as Figure 11 As shown, the automobile steering column at the present stage includes a column tube 1, a support member 2, a bracket assembly 3, a handle 4, and a handle bolt 5. The support member 2 and the two side plates 6 of the bracket assembly fix the column tube on the bracket assembly. When the current steering column collapses, it is necessary to cut off or destroy the limit parts of the length adjustment mechanism, which will increase the collapse force and affect the collapse effect of the steering column.

[0023] In view of the above problems, the steering column length adjustment mechanism of the present application has been invented, and the application will be described in detail below in conjunction with the accompanying drawings:

[0024] Such as figure 1 , 8 , 9, and 10, the steering column length adjustment mechanism includes a length limiting structure 7 (for limiting the length of the steering column), a retractable pin shaft 8, a sleeve 9, a...

Abstract

The invention relates to a steering column length adjusting mechanism. Comprising a length limiting structure, a telescopic pin shaft, a sleeve and a cam, the length limiting structure is fixed to the outer wall of a column tube of the steering column, the sleeve is fixed to a supporting piece outside the column tube, the telescopic pin shaft is inserted into the sleeve and penetrates through the sleeve, the telescopic pin shaft right faces a length adjusting limiting mechanism, one end of the cam is fixedly connected with a handle bolt, and the other end of the cam is fixedly connected with the handle bolt. The other end of the cam is arranged on the outer side of the pin shaft, the cam presses the telescopic pin shaft inwards, and the inner side face of the lower end of the cam comprises a high plane and a low plane. According to the adjusting structure, the collapsing function and the length adjusting function of the steering column are separated, and the problems that in the prior art, when the steering column collapses, a limiting part can be cut off or damaged, meanwhile, large force is generated, the large force fluctuates on the overall collapsing force, the collapsing force is increased, and the collapsing function is affected are solved.

Description

technical field [0001] The invention relates to the field of automobile steering columns, in particular to a steering column length adjustment mechanism. Background technique [0002] When a car collides violently, the steering wheel will hit the driver. In order to reduce the impact force suffered by the driver, the steering column of the car is designed as a collapsible structure, which can disperse some of the impact force transmitted from the steering column to the human body due to the impact. . [0003] The steering column length adjustment mechanism in the prior art includes a chute arranged on the outer peripheral support of the column tube and a limiting part arranged on the outer circumference of the column tube. The limiting part is placed in the chute, and when the steering tube is adjusted in length, the limit Bit parts are used for limit. However, when the vehicle is subjected to a strong impact and the steering column collapses, the limiting parts will be cu...
