Embodiment Construction

[0024] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0025] Such as figure 1 with figure 2 As shown, the steering column of this embodiment includes: an input shaft 10 , an outer casing 20 , an inner casing 30 , an electromagnetic device 40 and a control device 50 . Wherein, the input shaft 10 is connected with the first steering device and rotates synchronously. The outer sleeve 20 is sheathed on the outside of the input shaft 10 , the outer sleeve 20 and the input shaft 10 are relatively rotatable, and the relative positions of the outer sleeve 20 and the input shaft 10 in the axial direction remain unchanged. The inner sleeve 30 is sleeved between the outer sleeve 20 and the input shaft 10 , the inner sleeve 30 and the outer sleeve 20 can ...

Abstract

The invention provides a steering column, a steering system, a vehicle and a steering column collapse control method. The steering column comprises an input shaft, an outer sleeve and an inner sleeve, wherein the outer sleeve sleeves the outer side of the input shaft and rotates relative to the input shaft, axial relative positions of the outer sleeve and the input shaft are unchanged, the inner sleeve can axially slide relative to the outer sleeve, and circumferential relative positions of the inner sleeve and the outer sleeve are unchanged. When pre-collision signals are not received by a control device, an electromagnetic device applies first attractive force to the inner sleeve, so that the relative positions of the inner sleeve and the outer sleeve are unchanged. When the pre-collision signals are received by the control device, the control device applies second attractive force to the inner sleeve, and the inner sleeve slides relative to the outer sleeve. When the outer sleeve slides to a preset position, the control device controls the electromagnetic device to apply the first attractive force to the inner sleeve. The steering column can effectively solve the problem of poor protection performance of a steering column in the prior art.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a steering column, a steering system, a vehicle and a method for controlling the collapse of the steering column. Background technique [0002] At present, in order to ensure the driving safety of the driver, the steering system of the vehicle generally includes a steering wheel, a steering column connected to the steering wheel, and a steering gear. The collapse force of the steering column comes from the riveting of the inner and outer sleeves and the injection molding of the spline groove of the intermediate shaft. The collapse force can only be guaranteed within a certain range, and the collapse force limit cannot be accurately provided. The consistency of the collapse force is poor; in addition, the passive collapse structure cannot accurately and reasonably provide the collapse force when the vehicle collides, nor can it accurately and actively control the collapse distance. Small ...
