A collapsible and anti-shedding energy-absorbing automobile steering column

Abstract

The invention relates to a collapsible anti-falling energy absorption type automobile steering pipe column, which comprises an upper mandrel (1), an upper column pipe (2), a lower mandrel (7), a lower column pipe (8) and a lower installing support frame (6), and is characterized by also comprising an upper installing bracket assembly (3) and a regulating support frame (5), wherein the regulating support frame (5) is fixedly arranged on the upper column pipe (2), and is connected with an instrument cross beam through the upper installing bracket assembly (3); when collision occurs, relative movement occurs between the upper installing bracket assembly (3) and the regulating support frame (5), but disengagement does not occur, so that collapse is realized between the upper column pipe (2) and the lower column pipe (8) as well as between the upper mandrel (1) and the lower mandrel (7) for collision energy absorption. The automobile steering pipe column also comprises an energy absorption steel belt (4), wherein the energy absorption steel belt (4) is arranged between the upper installing bracket assembly (3) and the regulating support frame (5), and is connected with the upper installing bracket assembly (3) and the regulating support frame (5).

Description

technical field [0001] The invention belongs to the technical field of steering systems of passenger cars, and in particular relates to a collapsible and anti-falling-off energy-absorbing steering column for automobiles. Background technique [0002] With the popularity of automobile consumption, there are more and more automobile safety accidents, and the requirements for automobile safety are also getting higher and higher. When a high-speed car hits a low-speed or stationary object, the high-speed car will have a relatively large deceleration. According to Newton's law, the driver will continue to move forward due to inertia, causing head and chest The impact will be generated on the steering wheel, and the impact will be transmitted to the steering column through the steering wheel, and the steering column will in turn produce a reverse impact force on the driver's head and chest, thereby causing damage to the human body. [0003] The steering system consisting of the s...
