Steering column crush energy absorbing assembly for vehicle and automobile having same

Abstract

The invention discloses a steering column intrusion energy-absorbing assembly for vehicles and a vehicle provided with the same. The intrusion energy-absorbing assembly comprises a fixation bracket which is mounted on the vehicle body of the vehicle and provided with an energy-absorbing area; a steering column which is connected with the fixation bracket; a connection bracket which is arranged between the fixation bracket and the steering column and fixedly connected with the steering column and can move relative to the fixation bracket; and a friction plate which is arranged in the energy-absorbing area and fixedly connected with the connection bracket and can slide relative to the energy-absorbing area to decompose the action force on the friction plate. The steering column intrusion energy-absorbing assembly for vehicles in the embodiments completely utilizes the structures of the fixation bracket and the connection bracket, simplifies the intrusion energy-absorbing structure of the steering column, facilitates the inner arrangement in the vehicle, and reduces the production cost.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, more specifically, to a steering column collapse energy-absorbing assembly for a vehicle and an automobile having the same. Background technique [0002] In the case of a frontal collision of a car, the front cabin of the car will move towards the driver due to being blocked by obstacles, and during this process, the steering wheel of the car will tend to rush towards the driver's torso. In another case, when the car brakes suddenly or the speed of the vehicle drops sharply, the driver will tend to approach the steering wheel under the effect of inertia. If no safety structure is installed on the steering system of the car, in both cases, the steering wheel will collide with the driver's torso, posing a threat to the driver's personal safety. In order to reduce the injury to the driver, the national regulations require that the steering column has the function of collapsing and ...

Problems solved by technology

[0003] In the related art, the collapse forms and structures of the steering column are various, but the use of special guide structures and energy-absorbing structures will not only increase the development cost of the steering column, but also lead to the failure of the steering column structure. Complicated, affects the layout of the steering column on the vehicle, and brings difficulty to the structural design of the vehicle, so it needs to be improved
