A kind of front anticollision beam assembly of automobile, comprise the crossbeam for bearing shock and be fixedly connected on crossbeam two ends and extend back two energy absorption devices, it is characterized in that: described energy absorption device comprises and arranges front mounting plate and rear adapter plate along described crossbeam fore-and-aft direction, between described front mounting plate and described rear adapter plate, described crossbeam fore-and-aft direction is provided with shaped hollow round table bellows, described front mounting plate is connected with described crossbeam is detachable, the two ends of described shaped hollow round table bellows are fixedly connected on the medial surface between described front mounting plate and described rear adapter plate respectively, the larger diameter end of described shaped hollow round table bellows is positioned near described front mounting plate side, described front mounting plate is conical suface towards the side of described shaped hollow round table bellows side, and the line of centers of conical suface is coaxial with the line of centers of described shaped hollow round table bellows, described front mounting plate and described rear adapter plate offer lightening hole respectively.
In the present invention, when vehicle front receives shock, crossbeam bears whole impact, and is disperseed by collision energy, and pass to the energy absorption device being positioned at crossbeam two ends, shaped hollow round table bellows is collided after energy, and first its larger diameter end starts crumple.The contact surface of front mounting plate and shaped hollow round table bellows is conical suface, the action direction of power is perpendicular to conical suface, and to act on after on shaped hollow round table bellows be from inside to outside in the direction of this power, such shaped hollow round table bellows is when crumple, fragment is just outwards scattered, shaped hollow round table bellows interior can not be entered into counteract, make shaped hollow round table bellows can energy-absorbing crumple smoothly, improve the transfer capability to impact, also improve the safety of vehicle simultaneously.
As optimization, described crossbeam comprises rectangular cross tube and is positioned at rectangular cross tube front and the strip arch bar arched upward towards rectangular cross tube front, described rectangular cross tube and described strip arch bar are positioned in same level, the two ends of described strip arch bar are fixedly connected with the two ends of described rectangular cross tube respectively, multiple arch support frame along described rectangular cross tube length direction spread configuration is provided with between described strip arch bar and described rectangular cross tube, the vault of described arch support frame is fixedly connected with the side of described strip arch bar towards described rectangular cross tube side, two arch springings of described arch support frame are fixedly connected with the side of described rectangular cross tube towards described strip arch bar side respectively.The front of rectangular cross tube is provided with strip arch bar; multiple arch support frame is also provided with in addition between them; strip arch bar matches with arch support frame, is formed and is similar to the same structure of arch bridge, and the arcuate surface of strip arch bar is by tangentially passing to each arch support frame; collision energy is disperseed; be delivered to again in rectangular cross tube, make rectangular cross tube uniform force, can not be out of shape because local pressure is excessive; improve overall impact resistant capability, can actv. be protected by automotive engine.
As optimization, the honeycomb sandwich extended along described rectangular cross tube length direction is also provided with in described rectangular cross tube, described honeycomb sandwich comprises some honeycomb holes arranged along described rectangular cross tube fore-and-aft direction, and described honeycomb sandwich is fixedly connected with the inwall of rectangular cross tube respectively along the two ends of described honeycomb hole length direction.Honeycomb-like sandwich structure good stability, not yielding, its outstanding pressure resistance and resistance to bending can actv. Collision-frees.
As optimization, described strip arch bar is bonded with buffering foam block away from the side of described rectangular cross tube side covers.Buffering foam block is as energy-absorbing buffering material.It is after vehicle and pedestrian collision that its effect mainly contains two: one, can provide further buffering to pedestrian lower leg; Another provides support for bumper skin, ensures its not easy fracture or distortion when slight pressurized.
In sum, beneficial effect of the present invention is: structure of the present invention is simple, improves the transfer capability to impact, also improves the safety of vehicle simultaneously.
