Description
Technical field
The utility model is a kind of collapsing structure, in particular to a kind of multi-level crumple knot for promoting steering column performance
Structure.
Background technique
Tubing string in the prior art, rigid relative deficiency, when crumple occurs, there is the risk fallen in steering wheel.
Chinese patent 201720180751.5 discloses a kind of steering column collapsing structure, including steering column and and vehicle
The affixed mounting bracket of body, which is characterized in that the side of the mounting bracket offers guide groove along the steering column direction of motion,
That slides in the guide groove is equipped with guide pipe；The guide pipe is fixedly connected by fixing bolt with the steering column；
It further include the buffering steel band being located in the mounting bracket, one end of the buffering steel band is fixed on the peace of the guiding bottom of the tube
It fills on bracket, the other end of the buffering steel band is the freedom that the guide pipe is reversely bypassed along the guide pipe direction of motion
End；The guide pipe drives the free end to move along the guide groove.This structure is traditional structure, is unable to satisfy existing need
It asks, there is a certain security risk.
Summary of the invention
The utility model mainly solves the deficiencies in the prior art, provides a kind of compact-sized, which can be from
Many-sided multi-level crumple knot for promoting steering column performance of one kind for promoting steering column performance such as rigidity, crumple, intensity
Structure.
Above technical problems of the utility model are mainly solved by the following technical scheme:
A kind of multi-level structure for promoting steering column performance, including upper column tube and lower column tube, the upper column tube is under
Column tube is fixed in part overlapping, and the top of the upper column tube left end is equipped with middle bracket, is equipped with and middle branch in the upper column tube
Frame is in the adjusting bracket of matching type distribution, and the adjusting bracket is connect by retaining mechanism with main body.
Preferably, being equipped with sliding elongated slot in the middle bracket, it is equipped with a pair of and sliding in the adjusting bracket and grows
Slot is in the adjustable plate of matching type slide displacement, and adjustment hole is equipped in the adjustable plate, and the middle bracket drives upper prop pipe edge
Adjusting bracket is slided, and the upper prop pipe is socketed in adjusting bracket, the two side ends of the adjustable plate be respectively equipped with
The fixed bending supporting element of adjusting bracket, the adjustment hole and sliding elongated slot pass through pin activity orientation.
Preferably, there is the position that is overlapped of 70~80mm between the upper column tube and lower column tube, the upper column tube with
By 8 points of riveting positioning of circumference between lower column tube, every totally 4 points of circle riveting, riveting ring layer two is enclosed totally.
Preferably, the adjustment hole is strip inclined hole, the sliding elongated slot is horizontal strip hole, the sliding
The two side ends of elongated slot are equipped with the interference hole location with pin in matching type distribution, and the pin and sliding elongated slot are slided in interference type.
Middle bracket is welded on column tube, and design has a sliding elongated slot on middle bracket, and when crumple, upper column tube will together with middle bracket
Along sliding elongated slot sliding, the risk that steering wheel is fallen has been absolutely avoided.Adjusting bracket is attached by retaining mechanism and main body.
Direct processing mounting holes in adjusting bracket eliminate injection molding or other many and diverse techniques, simplify the same of technique to connect with vehicle body
When, improve the stability of crumple.Adjusting bracket increases the support of bending everywhere, mentions the intensity of adjusting bracket greatly
Rise, and then improve the rigidity of steering column totality, torsional strength etc..
Main body uses upper and lower column tube fission collapse type structure, and an elongated slot is processed on middle bracket, to crumple and suspension,
The support of bending everywhere is processed in adjusting bracket, to improve the rigidity of steering column, torsional strength and the stability of crumple.Together
When, the risk that steering wheel is fallen has been absolutely avoided, has been greatly improved safety.
Therefore, a kind of multi-level collapsing structure for promoting steering column performance provided by the utility model, it is compact-sized, into
One step promotes operating characteristics, improves security performance.
