Embodiment 1

[0035] see figure 1 , the present invention includes a steering column, a collapse bracket, an energy-absorbing steel belt, an adjusting bracket, and an angle adjusting device, wherein the head of the energy-absorbing steel belt 4 is bent upward and is provided with at least one rivet hole 4-2. In this example, the width of the head of the energy-absorbing steel strip is greater than the width of the rest of the energy-absorbing steel strip, so that two rivets 4-1 are arranged along the left and right sides of the head of the energy-absorbing steel strip, so as to ensure that the The linear movement of the steering column prevents the possible rotational movement of the energy-absorbing steel belt when there is only one rivet 4-1, and improves the stability and tension of the energy-absorbing steel belt when it moves.

[0036] see Figure 2 ~ Figure 4, the collapse bracket 3 is provided with wing plates 3-7 that are folded to the left and right sides at the bottom of the lef...

Abstract

The invention relates to the technical field of an automotive steering column, in particular to a collapsing anti-falling mechanism for the automotive steering column. The collapsing anti-falling mechanism for the automotive steering column is characterized in that the head of an energy adsorption steel band is bent upward and is provided with a rivet hole; a collapsing bracket is formed in a mode that the bottoms of both left and right lateral plates of a U-shaped plate with a downward rebate are respectively provided with wing plates which are folded outward; both the left and right wing plates are respectively of a shape of a step with a high front part and a low rear part; the rear edges of the wing plates are provided with n-shaped notches which are open backward; and a top plate of the U-shaped plate corresponding to the position of the rivet hole is provided with a slotted hole along the back-and-forth direction. Compared with the prior art, parts are reduced; the structure is simple; the steering column also can be avoided falling down when the collapse is implemented; the frequency and the stiffness of the steering column are strengthened; and meanwhile, gaps of 0.5mm are reserved among binding faces of the energy adsorption steel band, a regulating bracket and the collapsing bracket, so that the friction between the contact surfaces is reduced and the gaps are convenient to ensure the steering column to collapse.

Description

technical field [0001] The invention relates to the technical field of automobile steering pipe columns, in particular to an automobile steering pipe column collapse prevention mechanism. Background technique [0002] With the development of the automobile industry and the improvement of people's requirements for driving comfort and safety, the energy-absorbing steering system with angle adjustment function has been gradually applied. When a car collides violently, the driver tends to lean forward due to the strong stopping effect, and the chest of the human body will collide with the steering wheel. In order to reduce the impact force on the driver's chest impacted by the steering column In some cars, the steering column is designed to collapse in two to three stages due to external extrusion during impact, so as to disperse some of the impact force transmitted from the steering column to the human body due to the impact. [0003] At present, some collapsible steering colu...
