Feature of the present utility model also resides in,
Connect and be equipped with at least 3 through holes on securing member.
The two sides of brace rod are provided with curved indentations.
Collision prevention girders includes the substrate of curved surface, and substrate is connected with the Gong Ziliang that cross section is arc type, and the two ends of substrate concave surface are symmetrical arranged clamping plate.
It is provided with reinforcement between substrate and bow word beam.
The middle part of buck plate is provided with accumulation of energy cylinder, and accumulation of energy cylinder interior is fixed with spring, and one end of spring connects plunger, and plunger contacts with accumulation of energy cylinder face and is connected, and one end of plunger is welded in the middle part of the concave surface of substrate.
There is antirust coat on buck plate surface.
There is antirust coat on brace rod surface.
There is antirust coat on collision prevention girders surface.
The beneficial effects of the utility model are: girder steel anti-collision energy absorption device after this utility model one automobile, by welding arc type bow word beam on substrate, and reinforcement is set between Gong Ziliang and substrate, at utmost improve crashworthiness, and this design structure can form the first energy-absorbing district, absorption greater impact power, stress surface and loading angle are wider；Brace rod is welded between buck plate and substrate, one is to play support collision prevention girders effect, two are to increase the buffer distance between collision prevention girders and vehicle frame, three is that both sides curved indentations structure forms the second energy-absorbing district, effectively reduce and be transferred to Impact energy on vehicle frame, and it being prevented from collision prevention girders generation sidesway, energy-absorbing lost efficacy；Accumulation of energy cylinder is the 3rd energy-absorbing district, absorbs the huge energy that frontal impact produces, it is to avoid vehicle frame is impaired serious and protects rear passenger safety.
Accompanying drawing explanation
Fig. 1 is the structural representation of girder steel anti-collision energy absorption device after a kind of automobile of this utility model；
Fig. 2 is A-A structural representation in Fig. 1.
In figure, 1. buck plate, 2. connect securing member, 3. brace rod, 4. clamping plate, 5. collision prevention girders, 6. plunger, 7. accumulation of energy cylinder, 8. spring, 9. curved indentations, 10. bow word beam, 11. reinforcements, 12. substrates.
