Low-cost automobile steering column handle clamping mechanism

Abstract

The invention relates to the technical field of automobile steering column production assembly, specifically to a low-cost automobile steering column handle clamping mechanism. Left and right radial adjusting grooves are correspondingly formed in the left and right sides of a U-shaped bracket of a steering column assembly; the left end of a bolt is locked by a locking block after running through the steering column assembly; the locking block is mounted in the left radial adjusting groove in a matched manner; a radial stopping block is closely clamped between a handle and the U-shaped bracket;an adjusting rod on the radial stopping block penetrates into an arc adjusting groove of the handle; and the back of the radial stopping block is mounted in the radial adjusting groove in a matched manner. According to the low-cost automobile steering column handle clamping mechanism, by using the locking block and the radial stopping block to replace multiple parts such as a fixing cam and a plastic limit on the side of the handle, the number of the parts and the cost are reduced to a great extent; and meanwhile, the grooving in the U-bracket is eliminated, the part accuracy of the steeringcolumn assembly is guaranteed, the noises can be both reduced during locking and unlocking of the handle, and the friction between friction sheet mechanisms is reduced.

Description

technical field [0001] The invention relates to the technical field of automobile steering column production and assembly, in particular to a low-cost automobile steering column handle clamping mechanism. Background technique [0002] In order to allow each driver to have a suitable steering wheel distance and a comfortable driving experience, the steering column of the car will be equipped with a two-way or four-way adjustment mechanism. Considering that the steering wheel is not allowed to slip during the non-adjustment period, the adjustment mechanism must give sufficient column holding force; and this design purpose depends on a large number of parts, such as handle assembly, fixed cam on the handle side, plastic The limit, the handle pressure block contacting the upper column tube, the gasket, the handle guide sleeve, the spring, the bearing and the nut, etc. [0003] A large number of parts not only increases the cost, but also increases the complexity of the assembly...

AI Technical Summary

Problems solved by technology

[0003] A large number of parts not only increases the cost, but also increases the complexity of the assembly, and it is easy to have missing parts, which leads to the unqualified assembly of the steering column

[0004] There is a patent document with application number 201820438205.1 disclosing a steering column clamping system. A buffer groove is set on the U-shaped bracket, and the noise of the entire device is reduced by using the cooperation between the cam disc, the buffer member, and the buffer groove. To achieve the effect of pre-tightening, but slotting on the U-shaped bracket causes the problem of lower matching accuracy of other parts, and the structure of the buffer is complicated, and the manpower and material resources consumed in production are relatively large, but in the use of pre-tightening, It can only reduce vibration and noise, and cannot further improve cost issues and assembly rhythm issues
