Specific embodiment
The present invention will be further described with reference to the accompanying drawings and detailed description.
Embodiment 1: in embodiment as shown in Figure 1, a kind of frontal crash of vehicles energy-absorbing protection structure, including
Energy-absorbing front stall 1, energy-absorbing back seat 2, fixing bolt 3, fixture nut 4 and energy-absorbing spring 5, the fixing bolt include with
The bolt head 31 of front anticollision beam of automobile welding and the stud 32 welded with automobile front longitudinal beam；
The stud passes through energy-absorbing front stall and energy-absorbing back seat, and energy-absorbing spring is set in outside stud, and energy-absorbing spring is in energy-absorbing
Between front stall and energy-absorbing back seat；
The fixture nut is threadedly coupled with stud, upward in stud shaft: bolt head, energy-absorbing front stall, energy-absorbing spring, energy-absorbing
Back seat and fixture nut are sequentially arranged.
The energy-absorbing spring is a valute spring, and valute spring one end is miner diameter end, and valute spring is another
One end is bigger diameter end, and path section contacts energy-absorbing front stall, major diameter end in contact energy-absorbing back seat.Valute spring is mainly characterized by volume
Small, load is big, variation rigidity, and it is suitable for the big occasions of, load small in space, can effectively save space.
Pad 6 is arranged on the stud, pad is between energy-absorbing back seat and fixture nut, after pad contacts energy-absorbing
Seat, pad contact fixture nut.The tightness degree of contact can be improved in pad, strengthens fixed effect.
The energy-absorbing front stall is equipped with opening towards tank in the front stall of energy-absorbing back seat, and energy-absorbing back seat is equipped with opening direction
Tank in the back seat of energy-absorbing front stall, when energy-absorbing front stall is contacted with energy-absorbing back seat: tank and the common structure of tank in back seat in front stall
At spring containing cavities, and energy-absorbing spring is in spring containing cavities.When energy-absorbing front stall and energy-absorbing back seat contact, energy-absorbing spring is in
In spring containing cavities, the problem of energy-absorbing spring causes energy-absorbing effect not give full play to because of radial deflection, distortion can avoid, it can
Stability during each arrangement works of effective guarantee.
The stud is equipped with several flexible barbs 33, stud axis horizontal, and flexible barbs one end is connecting pin, and elasticity is fallen
The thorn other end is free end, connecting pin and Stud connection, has deformation gap between free end and stud, upward in stud shaft:
It is sequentially arranged at energy-absorbing front stall, free end, connecting pin and energy-absorbing back seat.
When frontal crash of vehicles, energy is transmitted by front anticollision beam of automobile, and energy-absorbing front stall is by thrust, towards energy-absorbing back seat
Mobile (fixing bolt also moves together), energy-absorbing spring are compressed, and energy-absorbing back seat is supported (energy-absorbing back seat by automobile front longitudinal beam
Relatively fixed with stud, stud is welded with automobile front longitudinal beam).Until energy-absorbing spring be compressed to it is a certain amount of after, stud
Upper two flexible barbs pass through energy-absorbing back seat, and (stud passes through energy-absorbing back seat, necessarily has corresponding hole location on energy-absorbing back seat, elasticity is fallen
Thorn is exactly across the hole location), will it is locked between energy-absorbing front stall and energy-absorbing back seat (at this time energy-absorbing front stall contacted with energy-absorbing back seat and
It is relatively fixed), energy is completely converted into elastic potential energy and is stored.
Embodiment 2: the basic structure and embodiment of the present embodiment with embodiment 1, the difference is that, extremely such as Fig. 2
Shown in Fig. 4, the energy-absorbing back seat is equipped with several and one-to-one hangnail of flexible barbs and squeezes through hole 21, sets on energy-absorbing front stall
There is front stall mesoporous 11, energy-absorbing back seat is equipped with back seat mesoporous 22, and stud passes through front stall mesoporous, and stud passes through back seat mesoporous, hangnail
Hole is squeezed through to be connected to back seat mesoporous.The presence in hole is squeezed through, the difficulty that flexible barbs pass through energy-absorbing back seat can be reduced, improves work
When smoothness.
Institute's energy-absorbing front stall is equipped with guide rod 34, and energy-absorbing back seat is equipped with the pilot hole being slidably matched with guide rod, guiding
Bar passes through pilot hole 23.Guide rod can effectively be oriented to stud, improve stability and the position of energy-absorbing front stall moving process
Set accuracy.
It further include the backrest air bag cushion being arranged on driver seat in the car and setting in enging cabin and for being directed to
The deflation trigger switch 7 of bar contact, backrest air bag cushion are equipped at least five venting solenoid valve, deflation trigger switch and automobile ECU
Electrical connection, all venting solenoid valves are electrically connected with automobile ECU, when energy-absorbing front stall is contacted with energy-absorbing back seat, guide rod contact
And touch deflation trigger switch.Since automobile is head-on crash, the malformations such as enging cabin are be easy to cause, and cause to oppress
To driver's body, driver is damaged.After energy-absorbing front stall touches energy-absorbing back seat, guide rod contacts and touches deflation
Trigger switch, touching deflation trigger switch controls each venting solenoid valve by automobile ECU while deflating, in this way, script backrest
The space that air bag cushion occupies is just empty out, is passively avoided for driver, so as to effectively protect to driver.
More setting venting solenoid valves are to make every effort to provide bigger passive keep away in a short time for driver to ensure deflation fast speed
Allow space, venting solenoid valve specific number can be designed selection according to actual needs (can also increase the row of venting solenoid valve
Port diameter).
