Embodiment Construction

[0040] It should be noted that, in the case of no conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0041] The present invention will be described in detail below with reference to the drawings and in combination with embodiments.

[0042] According to one aspect of the present invention, a collapse energy-absorbing sleeve is provided. The collapse energy-absorbing sleeve 5 includes a tube body 51 and a crush sheet 52 fixed to the tube body 51, wherein the bottom of the crush sheet 52 The end is fixed on the circumferential wall of the tubular body 51, and the top end of the crush plate 52 protrudes from the circumferential wall of the tubular body 51 toward the inside and / or the outside of the tubular body 51, and the crush plate 52 is subjected to pressure along the axial direction of the tubular body 51. Capable of collapsing under stress.

[0043]The above-mentioned collapse energy-absorbing sleeve 5 can ...

Abstract

The invention relates to the field of buffer energy absorption, and provides a collapsing and energy absorbing sleeve, a transmission shaft assembly, a steering column assembly and a steering column collapsing and energy absorbing method. The collapsing energy absorbing sleeve comprises a tube body and a collapsing sheet fixed to the tube body, wherein the bottom end of the collapsing sheet is fixed to the circumferential wall of the tube body, the top end of the collapsing sheet faces the inner side and / or the outer side of the tube body and protrudes from the circumferential wall of the tubebody, and the collapsing sheet can be deformed by collapsing when receiving force in the axial direction of the tube body. The collapsing and energy-absorbing sleeve has a simple structure, a low manufacturing cost and a small arrangement space, and can effectively absorb impact energy.

Description

technical field [0001] The invention relates to the field of buffer energy absorption, in particular to a collapse energy absorption sleeve, a transmission shaft assembly, a steering column assembly and a method for collapsing energy absorption of the steering column. Background technique [0002] The steering column assembly of a car is a component that is connected to the steering wheel in the steering system of the car. With the improvement of people's requirements for automobile safety, the steering column assembly is required to have a certain collapse and energy absorption effect, so that when the car collides, the steering column can move and collapse, reducing the damage to the driver. [0003] The traditional structural forms of the collapse energy-absorbing device of the steering column mainly include the insert shearing and detachment type and the steel wire deformation energy-absorbing type. The collision energy is absorbed by shearing the insert and stretching t...
