To movement, in the process, the steering wheel of automobile has the trend for rushing at driver's trunk.In another case, when automobile is prominent
When so brake or speed fall sharply, driver can produce the trend near steering wheel in the presence of inertia.If not in automobile
Steering on safeguard construction is set, then in both cases, the danger that the trunk of steering wheel and driver can collide
Danger, makes the personal safety of driver constitute a threat to.To reduce the injury to driver, national legislation requirement steering column is in collision
During possess the function of crumple energy-absorbing.
In the related art, the crumple form and structure of steering column are varied, but use special guide frame
With the part such as endergonic structure, can not only increase the development cost of steering column, and also result in the complexity of steering column structure
Change, arrangement of the influence steering column on vehicle, the structure design to automobile brings difficulty, it is therefore desirable to be improved.
Utility model content
In view of the shortcomings of the prior art, main purpose of the present utility model is to provide a kind of simple structure installation side
Just the energy-absorbing component of the good automobile steering pipe column holder of energy-absorbing effect.
To achieve the above object, the utility model provides following technical scheme：A kind of suction of automobile steering pipe column holder
Energy component, including fixed block, energy-absorbing piece and fastener, the energy-absorbing piece include the fixing hole for being connected with fixed block
And passing through fixed pin connection with the close-connected connecting hole of fastener, the fixing hole and fixed block, the fastener includes
Bolt and pad, the fastener can be provided with along connection Relative sliding, on the energy-absorbing piece near one end of fixing hole to be determined
Position flanging, the positioning flanging is fastened on the seamed edge of fixed block, and the fixed block is fixedly connected with vehicle body by being molded pin.
Preferably, the connecting hole is shaped as kidney-shaped.
Preferably, the global shape of the energy-absorbing piece is rectangle, and the fixing hole is with connecting hole each along energy-absorbing length of a film
Degree direction is set and axisymmetrical of the fixing hole with connecting hole both with respect to energy-absorbing piece is set.
Preferably, the length of the connecting hole is 40 ~ 60mm.
The utility model has the following advantages that relative to prior art, when steering column occurs crumple, firstly because solid
Determine block to be fixedly connected by steady pin with energy-absorbing piece, and the injection pin being used to lock between fixed block and vehicle body can be broken,
Now fixed block can be slided with energy-absorbing sector-meeting because potential energy occurs relative displacement with fastener between fastener and energy-absorbing piece
Friction, fastener is slided along connecting hole length direction, the resistance that this frictional force is absorbed by energy-absorbing component.Fastener is bolt
It is the energy-absorbing size of adjustable energy-absorbing component, the length of connecting hole by the elasticity between regulating bolt and energy-absorbing piece with pad
Spend the crumple stroke for steering column.The effect one for positioning flanging is to assemble for convenience so that energy-absorbing piece and fixed block can be with
Quick alignment, facilitates the assembling of fixing hole, and two is to position flanging to overcome stiction between fixed block and energy-absorbing piece.This
The energy-absorbing modular construction of utility model is simple, and easy for installation, energy-absorbing effect is good.

Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of energy-absorbing component of automobile steering pipe column holder, including fixed block 1, energy-absorbing piece 2 and fastening
Part 3, the energy-absorbing piece 2 include for fixed block 1 be connected fixing hole 21 and with the close-connected connection of fastener 3
Hole 22, the fixing hole 21 passes through fixed pin connection with fixed block 1, and the fastener 3 includes bolt 31 and pad 32, described tight
Firmware 3 can be provided with positioning flanging 23 on the energy-absorbing piece 2 along connection Relative sliding near one end of fixing hole 21, described
Positioning flanging 23 is fastened on the seamed edge 11 of fixed block 1, and the fixed block 1 is fixedly connected with vehicle body by being molded pin.（Steady pin
Drawn not in the drawings with injection pin）
A kind of course of work of the energy-absorbing component of automobile steering pipe column holder of the present utility model is, in normal state,
Energy-absorbing piece 2 is fixedly connected with fixed block 1 and fastener 3 respectively, and relative static conditions are between three；Occur in steering column
During crumple, firstly because fixed block 1 is fixedly connected with energy-absorbing piece 2 by steady pin, and it is used to lock between fixed block 1 and vehicle body
Injection pin can be broken, now fixed block 1 and energy-absorbing piece 2 can be because there is relative displacement, fastener in potential energy with fastener 3
