Steering column regulating mechanism

Abstract

The invention relates to a steering column regulating mechanism which comprises a supporting mechanism which is connected with a steering column, can be used for supporting the steering column to rotate relative to a vehicle body and is connected with the vehicle body. The regulating mechanism also comprises a power device and a mounting box, wherein the power device is used for driving the steering column to rotate; the mounting box is connected with the vehicle body and used for supporting the power device; and the power device comprises a motor, a worm rod in transmission connection with the motor, a worm wheel engaged with the worm rod, a gear coaxially connected with the worm wheel and a rack which is engaged with the gear and fixedly connected with the steering column. Compared with the traditional steering column regulating mechanism, the steering column is set to be a structure capable of rotating relative to the vehicle body; when a steering wheel is needed to give the position to a driver or is adjusted to a proper position, the power device operates the steering column to ensure that the steering column rotates for a certain angle to meet requirements. The invention has the characteristics of simple structure and good practicality.

Description

【Technical field】 [0001] The invention relates to the field of vehicle steering, in particular to an adjustment mechanism for a steering column. 【Background technique】 [0002] The change of the driving direction of the car is realized by the driver changing the deflection angle of the steering wheel (usually the front wheel) by manipulating the steering system. It can also overcome the steering caused by the wheels due to the lateral interference of the road surface, and restore the original driving direction of the car. Automobile steering system generally consists of three parts: steering mechanism, steering gear, and steering transmission mechanism. The steering mechanism includes steering wheel, steering shaft and other components. The worm and sector gear at the lower end of the steering shaft form the steering gear. , the torque amplified by the steering gear is transmitted to the steering transmission mechanism, the steering transmission mechanism is hinged with the...

Problems solved by technology

[0003] The steering wheel is connected to the steering gear through the steering shaft, the steering column is sleeved on the steering shaft and supports the steering wheel, and the steering column positions the steering shaft; when it is necessary to adjust the driving direction of the vehicle, the force is transmitted to the steering gear, steering transmission Mechanism, the steering transmission mechanism transmits the motion and power output by the steering gear to the steering wheels to realize the steering of the vehicle; the steering wheel is a part directly operated by the driver, and the setting of its spatial position directly affects the comfort of the driver. In some models, the spatial position of the steering wheel is basically above the driver's seat. This structural setting makes it extremely inconvenient for the driver to get in and out of the car, especially for some small cars, which affects the driver's driving comfort.

[0004] In order to solve the above-mentioned technical defects, the Chinese patent with the publication number CN201224429 discloses an adjustable steering column for vehicles, which can adjust the spatial position of the steering wheel by adjusting the steering column, which includes a steering shaft 1' disposed inside the housing , a transmission shaft is connected with the steering shaft 1', and a left locking handwheel 2' and a right locking handwheel 3' are symmetrically arranged on the shell, and the left locking handwheel 2' is connected with a fixed Cooperate with the assembly bracket 4' of the casing to control the front and rear swing of the steering shaft 1' relative to the casing, and the right locking hand wheel 3' cooperates with the steering shaft 1' itself to control the up and down of the steering shaft 1' relative to the casing move, such as Image 6 shown; but this structural setting for adjusting the steering column is not convenient for the driver to operate, and the two locking handwheels are easy to wear after repeated adjustments, resulting in the failure of the adjustment function
