Abstract

The invention discloses an automobile intelligent crumple type steering column system which comprises a steering column, a driving module, a collision sensing module and a control module, the steering column comprises a crumple sleeve, an upper outer pipe and a lower inner pipe, the crumple sleeve is provided with an upper sleeve, a transition sleeve and a lower sleeve, the outer periphery of the upper sleeve is clamped with the inner side face of the upper outer pipe, and the transition sleeve is clamped with the inner side face of the lower inner pipe; the inner side face of the upper sleeve is fixedly connected with the outer side of the lower inner pipe, a fracture part is formed on the transition sleeve, and a step abutting against the lower end face of the upper outer pipe is arranged on the lower sleeve. The collision sensing module judges whether collision reaches a collision breaking point of the steering column or not at the moment when the vehicle collides, and sends a collision signal to the control module when judging that the collision reaches the collision breaking point; the control module controls the driving module to drive the step to move downwards when receiving the collision signal, so that the crumple sleeve is fractured at the fracture part; according to the intelligent crumple type steering column system for the automobile, when a head-on collision occurs, the steering column can crumple before a driver collides with a steering wheel.

Description

technical field [0001] The invention designs the technical field of automobile steering column, in particular to an automobile intelligent collapsible steering column system. Background technique [0002] The steering column is an essential part of the vehicle steering system, and its function is to transmit the rotational motion of the steering wheel to the steering gear, thereby realizing the steering of the vehicle. When the car crashes, because the car suddenly stops moving, the driver will rush forward quickly under the action of inertia, and the human chest will collide with the steering wheel. The collapsible steering column can be collapsed and deformed according to the pre-design, reducing the damage caused by the impact of the steering column on the driver's chest. However, the moment the human chest hits the steering wheel must have already caused a certain degree of injury to the driver, so it is necessary to design a structure or method to solve the above probl...
