Safe steering column structure

Abstract

The invention discloses a safe steering column structure capable of highly protecting drivers, relates to steering systems of automobiles, and solves the technical problems that the existing safe steering column structure is complex in structure and difficult to process and mount, possibility of secondary damage to drivers due to rebound of springs, and steering wheels are difficult to return. The safe steering column structure comprises a steering column assembly, an upper mounting support of the steering column assembly, a lower mounting support of the steering column assembly, a mounting support base fixed on a car body and an optional gas stopping spring, wherein one end of the upper mounting support of the steering column assembly is fixedly connected with the mounting support base through a shear pin, an anti-falling dowel is arranged between the upper mounting support of the steering column assembly and the mounting support base, and the other end of the upper mounting support of the steering column assembly is fixedly connected with the upper end of the steering column assembly; the upper end of a pressure pipe of the optional gas stopping spring is connected with the mounting support base; and one end of the lower mounting support of the steering column assembly is connected with the lower end of a piston rod of the optional gas stopping spring, and the other end of the lower mounting support of the steering column assembly is fixedly connected with the lower end of the steering column assembly.

Description

technical field [0001] The invention relates to an automobile steering system, in particular to a safety steering column structure with an energy-absorbing structure. Background technique [0002] When a car collides head-on, the steering wheel installed on the upper end of the steering column will move backward, that is, toward the driver's chest, and the driver will rush towards the steering wheel due to inertia, so it is very easy to cause a collision between the driver and the steering wheel , causing personal injury to the driver. In order to reduce the damage to the driver in the frontal collision of the car, the steering wheel is usually installed with a safety steering column structure with an energy-absorbing structure, so that when the collision force between the driver and the steering wheel reaches the set level, the steering column will absorb The function structure starts to work, and the steering column will collapse along its length, thereby limiting the max...

Problems solved by technology

[0007] The first object of the present invention is to solve the complex structure of the steering column existing in the safety steering column structure with an energy-absorbing structure in the prior art, and the manufacturing and processing And the installation is difficult, the driver has the technical problem that the driver may be injured twice due to the rebound of the spring, and a safety steering column structure with a simple structure can be provided that can effectively avoid the event that the spring rebound hurts the driver; the first embodiment of the present invention The purpose of the second invention is to solve the problem that the safety steering column structure with an energy-absorbing structure in the prior art triggers the work of the energy-absorbing structure. The rear steering system loses the operation function, which reduces the driver's self-rescue opportunities in some cases, and is not conducive to reducing the technical problem of road cleaning and dredging costs. It provides a shear pin with low shear strength and easy recovery of the steering system operation function. A Safe Steering Column Structure with Good Protection
