Abstract
The utility model relates to a collapsing energy absorbing structure of a steering column. The collapsing energy absorbing structure comprises a mounting upper bracket on which an energy absorbing strip and a shearing block are arranged, wherein the energy absorbing strip is fixed on the surface of the mounting upper bracket by the shearing block. Through the adoption of a simple structure, a collision and collapsing energy absorbing function of the steering column is achieved, the energy absorbing force is more accurately controlled and the energy absorbing force is very convenient to adjust; meanwhile, as the energy absorbing strip is mounted on the mounting upper bracket, the collapsing energy absorbing structure of the steering column, provided by the utility model, has the advantages of low cost and mounting simplicity.
Description
Technical field
The utility model belongs to automobile technical field, relates to a kind of endergonic structure, particularly a kind of steering column crumple endergonic structure.
Background technology
Occur in the traffic accident of serious collision at automobile, the bearing circle of automobile steering system often causes direct injury to hot body, in case automotive front end is collided, move behind the machinery space etc., bearing circle also with after move, space between bearing circle and the driver seat dwindles suddenly, and chaufeur is clipped in the middle and comes to harm.In order to reduce the generation of this injury as far as possible, automobile designers is started with from length and the angle variation of bearing circle, so that automobile steering system is except guaranteeing that the turning efficiency, the injury that chaufeur is subject to eases down to minimum when automobile bumps.Relevant is exactly the appearance of the technology of automobile energy-absorbing steering hub column therewith, and the automobile energy-absorbing steering hub column is redistributed the impulsive force that passes on the bearing circle when automobile bumps, and the impulsive force path is shunted rapidly, so that the load that is delivered on the bearing circle is minimum.Steering column is made of hollow tubular and steering shaft.The hollow tubular of conventional steering tubing string and steering shaft are all-in-one-piece, and the steering shaft upper end is connected with bearing circle, and the lower end is connected with direction device.And the characteristics of energy-absorbing steering hub column are that the Integral steering tubing string is divided into two, and are divided into steering column and lower steering column two parts; The steering shaft of the inside also is divided into two-section, connects with universal joint mechanism between them.Make direction mechanism produce displacement in case bump, the special steering shaft in universal-joint lower end can fold, and upper steering column moves in the lower steering column, realizes crumple, thus the expansion space harm reduction.
But this steering column can only be the primary collision energy-absorbing, energy-absorbing effect is poor, can not well play buffer action, and the cliding friction of top steering column and lower steering column and turn upward axis and lower shaft between the friction absorbing impact energy, because column jecket is interference fit up and down, wayward between cooperation, cause the friction force conformability relatively poor, turn upward axis and turn to the friction force between next week also wayward, thereby cause tubing string crumple power scope larger, conformability is poor, and is also wayward to the injury of chaufeur, and individual other can cause serious consequence.
Chinese patent notification number CN 201169287 Y, December 24 2008 day for announcing, name is called the energy absorption device of energy-absorbing steering tube column, this application case discloses a kind of energy absorption device of novel energy-absorbing steering tube column, basis at multistage collapsing structure commonly used has at present increased a pair of energy-absorbing sheetmetal, this energy-absorbing sheetmetal is cutting a leg-of-mutton tearing groove according to the pulling force of tearing of design along its length direction, formed relatively uniformly zone of a peel strength.Its weak point is, the crumple endergonic structure design of steering column is comparatively complicated, and the accurate control of energy-absorbing power is difficulty comparatively.
The utility model content
The purpose of this utility model be for the crumple endergonic structure design that solves the prior art steering column comparatively complicated, the accurate control of energy-absorbing power comparatively difficulty defective and a kind of steering column crumple endergonic structure is provided.
To achieve these goals, the utility model is by the following technical solutions:
A kind of steering column crumple endergonic structure comprises and installs support, and the described support of installing is provided with energy-absorbing band and cutout, and described energy-absorbing band is fixed on by cutout and installs rack surface.In the technical program, with some energy-absorbing bands with cutout with install support and be connected, when external force acquired a certain degree, the energy-absorbing band slowly was out of shape, and prolonged the attack time, reduced the impact dynamics.
As preferably, the described cradle back top of installing is provided with horizontal flat board, and described horizontal flat board is provided be used to the through hole that passes the energy-absorbing band.In the technical program, the horizontal flat board of installing cradle back top is used for supporting steering column, and laterally flat board is provided with 2 holes, so that the energy-absorbing band passes.
As preferably, described energy-absorbing band is the energy-absorbing steel bar.In the technical program, the energy-absorbing power of energy-absorbing steel bar is better, and intensity is enough simultaneously.
As preferably, described cutout is provided with several fixed orifices that is used for the fixed shear piece.In the technical program, can cutout be fixed on by injection moulding process and install on the support, the injection moulding rod is injected fixed orifice, cutout is fixed.
As preferably, described cutout bottom is provided with the through hole that passes for the energy-absorbing band.In the technical program, the energy-absorbing band passes cutout, and when crumple, the stressed injection moulding rod with the fixed shear piece of energy-absorbing steel bar is broken, and absorbing forces of impact prolongs the attack time.
As preferably, cutout is passed in the bottom of described energy-absorbing band, and energy-absorbing band top is passed and installed cantilever tip and extend to the back side and pass horizontal flat board.In the technical program; the part of energy-absorbing steel bar is at the back side of installing support; a part is in the front of installing support; after collision occurs, when external force acquires a certain degree, the stressed slowly distortion of energy-absorbing steel bar; injection moulding rod on the cutout is broken; prolong the attack time, reduce the bump dynamics, the protection chaufeur.
The beneficial effects of the utility model are, structure ease in use realizes steering column collision crumple energy-absorbing function, and the control of energy-absorbing power is comparatively accurate, and energy-absorbing power is regulated very convenient; Owing to installing support installation energy-absorbing band, cost increases little, installs simple simultaneously.
