Abstract
The utility model discloses a steering column safety ulcerate structure that contracts, include tubular column, panel board crossbeam and fix the installing support on the panel board crossbeam, be equipped with the spout on tubular column or the installing support, installing support or tubular column and spout sliding connection. The beneficial effects of the utility model are that: safety and reliability.
Description
Technical field
This utility model relates to a kind of automobile component, specifically a kind of steering column collapsing structure, can provide safety guarantee to driver when there is accident collision.
Background technology
Automobile turning pipe pillar assembly one end connects steering wheel, and one end connects wheel steering mechanism, is the necessary parts of driver's operating and controlling vehicle, needs to have reliability and the safety of height.When automobile normal running, steering column must have enough strength and stiffness to ensure normal delivery steering torque；And when accident collision occurs, steering column needs again good crumple ability so that it is self can be compressed and absorb collision energy, such that it is able to well prevent or alleviate driver's injuries.The Chinese patent literature of Publication No. " CN204077775U ", " a kind of diecast magnesium alloy steering column " within 17th, is disclosed in JIUYUE in 2014, generally tubulose, in the corresponding position that the governor motion of steering wheel regulation handle is installed, regulation block it is provided with on described steering column, three limits of described regulation block depart from steering column, are connected on steering column.This steering column passes through one-step die casting, the accuracy of form and position of part is high, simultaneously because magnesium alloy light specific gravity, damping characteristics can meet well lightweight and the requirement of head-on crash absorption energy, simultaneously, this steering column simple in construction, it is not necessary to crumple pipe just can be controlled and realize the regulation of the working depth to steering wheel and angle by additional mechanism easily.The collapsing structure of such standard machinery tubing string existing is to be provided with mounting bracket on tubing string, and mounting bracket fastens with CCB by pulling block, when car load collides, and tubing string stress, departed from by mounting bracket and pull block and CCB, it is achieved crumple.Such design still has certain safety defect: after crumple occurs, and mounting bracket departs from CCB, and tubing string carries steering wheel and air bag becomes free end, is affected by gravity whereabouts, easily clashes into driver's thigh, causes the risk of secondary injury.
Summary of the invention
This utility model technical issues that need to address are, existing steering column collapsing structure lacks necessary spacing measure to the tubing string after crumple, thus provides a kind of safe and reliable steering column collapsing structure.
To achieve these goals, this utility model adopts the following technical scheme that a kind of safe collapsing structure of steering column, including tubing string, instrument panel beam and the mounting bracket being fixed on instrument panel beam, described tubing string or mounting bracket are provided with chute, described mounting bracket or tubing string and are connected with described slide.
In order to change steering column situation of upper end free falling when crumple in traditional scheme, the technical program Design of mounting plate has become and has been fixed together with instrument panel beam, will not be taken off by related pulling when crumple.Simultaneously need to ensure crumple effect, i.e. needing to include the upper end of tubing string to connect the parts such as the steering wheel air bag that is arranged on upper end effectively can decline with tubing string, and this programme devises chute on tubing string, then becomes to be connected with slide by Design of mounting plate.When crumple occurs, chute defines the glide direction of tubing string.Chute can also be arranged in mounting bracket, and from limit effect, two kinds of set-up mode differences are little.
As preferably, described tubing string is provided with chute, and described mounting bracket is connected with described slide.For Layout-Angle, art chute designs, on tubing string, can effectively alleviate tubing string heavy amount, and inertia when crumple occurs also can be less, is more beneficial for protecting the safety of human pilot.
As preferably, the glide direction of described chute is axially in parallel with tubing string.Tubing string is axially the direction previewing confirmation, and in the case of normal driving, dead ahead no one's body region of the direction exists, when crumple occurs, tubing string axially anterior displacement, will not cause secondary injury to human pilot.
As preferably, described tubing string is telescoping tube, is socketed in outer for upper tubing string, is socketed in interior for lower tubular column, and upper tubing string is circumferentially fixed with lower tubular column；Described chute is located on tubing string.In order to realize more preferable crumple effect, design of string pipe is the telescoping tube of two sections by this programme, if it occur that crumple, then upper-lower section can shrink, and reduces the generation bending, rupturing the fragment spine caused；Meanwhile, expansion link has more preferable guidance quality, more accurate to the direction controlling of crumple, can reduce may injure human pilot greatly.In order to allow telescoping tube can effectively transmit moment of torsion in normal state, this programme is circumferentially fixed with lower tubular column by upper tubing string.Fixing mode can be gear engagement, use non-round tube as different schemes such as telescoping tubes.
As preferably, carry out radially connected between described upper tubing string and lower tubular column in the way of riveting.This programme selects the mode of riveting to connect tubing string and lower tubular column.Moment of torsion can be effectively transmitted in riveting.The intensity of riveting is accurately set, and under the impact exceeding the stress being sized, riveting was lost efficacy, and crumple starts, and telescoping tube synchronizes retraction, to realize the protection to human pilot.
In sum, the beneficial effects of the utility model are: safe and reliable.
Accompanying drawing explanation
Fig. 1 is axonometric drawing of the present utility model,
Fig. 2 is the front view of Fig. 1.
Wherein: 1 tubing string, 2 mounting brackets, 3 instrument panel beams, 11 chutes, tubing string on 12,13 lower tubular columns, 14 riveting points, 21 slotted-guide pins.
Detailed description of the invention
With detailed description of the invention, this utility model is further described below in conjunction with the accompanying drawings.
The present embodiment is a kind of safe collapsing structure of steering column applied on certain brand car model, including tubing string 1, instrument panel beam 3 and mounting bracket 2.As shown in Figure 1 and Figure 2, tubing string is circular telescoping tube, and including upper tubing string 12 above and lower tubular column 13, both are riveted together by several riveting points 14, and the internal diameter of upper tubing string is more than the external diameter of lower tubular column.Being fixed with chute 11 on upper tubing string, the glide direction of chute is axially in parallel with tubing string.Mounting bracket is fixed on instrument panel beam by bolt pair；Mounting bracket is provided with slotted-guide pin 21, and slotted-guide pin passes chute, it is ensured that between chute and fixed support slidably.
The safe collapsing structure of a kind of steering column of the present embodiment, when normally using, upper tubing string passes through together with riveting with lower tubular column, when accident collision occurs, the upper end stress of upper tubing string exceedes preset value, and riveted structure is destroyed to lose efficacy, crumple starts, upper tubing string footpath slide downward, the chute being connected on tubing string also slide downward, the terminal of its sliding trace is formed by the end of chute is spacing.Through such spacing, the crumple effect of tubing string still keeps, but the tubing string after crumple will be still spacing by chute, without downwards the thigh of human pilot being produced strike.Therefore the safe collapsing structure of a kind of steering column of this example has more reliable safe effect than traditional technical scheme.
