Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to an anti-falling device for an automobile steering column body. Background Art

[0002] When a vehicle is involved in a serious collision, the human body will hit the steering wheel due to inertia, causing the pull-off block at the mounting position on the steering column (hereinafter referred to as the column) to detach from the column body. At this time, the column will rotate around the mounting bolts below it. When the collision force reaches a certain level, and the column does not have an anti-fall mechanism, the column may crush the plastic guard plate and then press on the driver's legs, which will bring additional difficulties to the rescue. Therefore, the anti-fall function of the column is very important. The existing anti-fall function of the column mostly relies on the end margin of the crushing force providing mechanism such as the tear strip and the energy absorption strip to achieve it; the columns that use other structures to provide crushing force mostly do not have an anti-fall function.

[0003] For example, the publication number CN105329308A disclosed a steering column assembly on February 17, 2016. The steering column can fall downward in a predetermined direction when the car collides, thereby reducing the damage caused by the steering column to the driver. The steering column assembly of the present invention includes a steering column with a collapse structure, a steering column bracket and an instrument crossbeam mounting bracket. The steering column bracket is connected to the instrument crossbeam mounting bracket by a pull-off block and an injection-molded pin. The key is that the steering column bracket is provided with a protruding guide column, and the top of the guide column is provided with an anti-slip portion; the instrument crossbeam mounting bracket is provided with a guide groove parallel to the axial direction of the steering column; the guide column is inserted into the guide groove and can move along the guide groove, and the width of the anti-slip portion is greater than the width of the guide groove. The above-disclosed steering column has no anti-falling function when in use, which makes it easy for the steering column to cause damage to the driver's legs, and the safety performance of the car is low. Summary of the Invention

[0004] The purpose of this utility model is to provide a higher safety performance automobile steering column body anti-fall device. The utility model prevents the steering column body from hitting the driver's legs when it falls by means of an elastic member provided between the pull-off block and the steering column body, thereby protecting the driver and improving the safety performance of the automobile.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model to solve its technical problems is: a car steering column body anti-falling device, including an instrument crossbeam and a steering column assembly arranged on the instrument crossbeam, the steering column assembly including a connecting frame and a steering column body, the connecting frame is connected to the instrument crossbeam, the connecting frame is connected to the steering column body, a pull-off block is provided on the connecting frame, and the steering column body and the pull-off block are connected by an elastic member.

[0006] The elastic member is a spring, one end of the spring is connected to the steering column body, and the other end of the spring is connected to the pull-off block.

[0007] Hooks are respectively provided at both ends of the spring, and the two hooks are respectively connected to the steering column body and the pull-off block.

[0008] An extension block is provided on the pull-off block, a transverse column is provided on the extension block, and the transverse column is connected with a hook.

[0009] A connecting plate is provided on the steering column body, and a through hole connected to the hook is provided on the connecting plate.

[0010] The horizontal column is provided with a hook groove connected with the hook.

[0011] The pull-off block is connected to the connecting frame via bolts.

[0012] The beneficial effects of the utility model are:

[0013] When the vehicle collides and the steering column body is separated from the connecting frame, the elastic member between the pull-off block and the steering column body blocks the steering column body from falling, thereby preventing the steering column body from hitting the driver's legs, thereby protecting the driver. In addition, the elastic member provided between the pull-off block and the steering column body can also work as a column angle adjustment assist mechanism, which is more practical.

[0014] The spring is used as an elastic part to realize the elastic connection between the pull-off block on the instrument cross beam and the steering tube pile, and the hook at the end of the spring is connected to the cross column on the extension block of the pull-off block, thereby realizing a convenient connection between the spring and the pull-off block, and the hook on the spring is connected to the through hole on the connecting plate on the steering column body, thereby realizing a stable connection between the spring and the steering column body.
