The specific embodiment
Fig. 1 to Fig. 3 shows a kind of lorry afterbody anticollision device embodiment of the present invention; this anticollision device comprises collision cross bar 2 and is installed in a double thread shear energy-absorbing mechanism 1 of lorry two sides of tail; screw thread shear energy-absorbing mechanism 1 comprises crank 11; connecting rod 12; energy-absorbing screw rod 14 and shearing slide block 13; energy-absorbing screw rod 14 is installed on the vehicle frame 5 of lorry; shearing slide block 13 is sheathed on the energy-absorbing screw rod 14; crank 11 upper ends and vehicle frame 5 are hinged; connecting rod 12 upper ends are hinged with shearing slide block 13; connecting rod 12 lower ends and crank 11 lower ends are hinged; collision cross bar 2 is connected in connecting rod 12 lower ends of a double thread shear energy-absorbing mechanism 1 or is connected in crank 11 lower ends of a double thread shear energy-absorbing mechanism 1; in the process of collision energy-absorbing; collision cross bar 2 with crank 11 and connecting rod 12 to lower swing; the car that can prevent to knock into the back pierces the lorry bottom; and connecting rod 12 will promote to shear the screw thread on the slide block 13 shear energy-absorbing screw rods 14 in the time of lower swing; the smooth absorption collision energy; can reduce the knock into the back causality loss of lorry of car greatly, for personnel and vehicle provide more effective safety precautions by bus.
In the present embodiment, be equipped with two connecting rods 12 in each screw thread shear energy-absorbing mechanism 1, each connecting rod 12 lower end is equipped with an obstruction block 4, obstruction block 4 is made of a dual-side 41 and a base 42, and base 42 is connected and fixed with collision cross bar 2, and dual-side 41 is connected and fixed with connecting rod 12, and dual-side 41 is downward-sloping gradually to collision cross bar 2 from connecting rod 12, produce downward inclination and distortion when obstruction block 4 withstands shocks, guiding collision cross bar 2 moves downward, and plays preventing that car from piercing the effect of lorry bottom.Collision cross bar 2 is provided with ripple energy-absorbing plate 3, when collision energy hour, the distortion by ripple energy-absorbing plate 3 just can absorb collision energy fully.Energy-absorbing screw thread on the energy-absorbing screw rod 14 is Acme thread, square thread, saw thread, round thread or triangle thread, selects square thread in the present embodiment for use.
Principle of work: when car taking place knock into the back the accident of lorry, the front bumper of rear car or vehicle body at first contact with ripple energy-absorbing plate 3, and ripple energy-absorbing plate 3 crimp under the impact force effect absorbs less energy simultaneously.After ripple energy-absorbing plate 3 is badly deformed, when still having collision energy not to be absorbed, then collision energy continues to front transfer, cause that obstruction block 4 along inducing to be directed downwards plastic deformation and absorption portion energy takes place, at this moment colliding cross bar 2 moves downward with the movable end of obstruction block 4, thereby reduced the height between collision cross bar 2 and ground, played preventing that car from piercing the effect of lorry bottom.When the distortion of obstruction block 4 reaches maximum, obstruction block 4 fits together with connecting rod 12, if at this moment also have a large amount of collision energies not to be absorbed, crank 11 and connecting rod 12 are rotated, connecting rod 12 will promote to shear slide block 13 to front slide simultaneously, energy-absorbing screw thread on the shear energy-absorbing screw rod 14 utilizes the power of shearing screw thread to be essentially this characteristic of constant force, the remaining collision energy of smooth absorption.For different car shapes; collision energy in the time of can rule of thumb estimating collision; then according to collision energy and 11 ground Clearances of crank; parameter to mechanism is optimized; it is absorbed energy in certain distance fully; thereby the geometry compatibility of two cars and rigidity compatibility when improving rear-end impact greatly, the crash survivability of protection personnel and vehicle.
Lorry afterbody anticollision device of the present invention is simple in structure, and easy accessibility can carry out swing to increase the crossing ability of vehicle to crank according to different road conditions; Of the present inventionly also can realize the classification anti-collision energy absorption, no matter be slight scraping or sharp impacts can improve crash survivability under the prerequisite that does not change the lorry agent structure, and maintenance cost is low, and is economical and practical, is convenient to promote.
Above-mentioned is preferred embodiment of the present invention, is not the present invention is done any pro forma restriction.Though the present invention discloses as above with preferred embodiment, yet be not in order to limit the present invention.Any those of ordinary skill in the art under the situation that does not break away from the technical solution of the present invention scope, can utilize the technology contents of above-mentioned announcement that technical solution of the present invention is made many possible changes and modification, or be revised as the equivalent embodiment of equivalent variations.Therefore, every content that does not break away from technical solution of the present invention, all should drop in the scope of technical solution of the present invention protection any simple modification, equivalent variations and modification that above embodiment did according to the technology of the present invention essence.
