The tail collision avoidance mechanism is obtained by modifying an original tail collision avoidance mechanism of a commercial vehicle, operation is simple and convenient, time and labor are saved, and the tail collision avoidance mechanism has good application and popularization prospects.
Description
Technical field
The utility model belongs to safety traffic and guard technology field, particularly relates to commercial vehicle/comm..vehicle anticollision mechanism.
Background technology
Along with the increase of automobile quantity,, the continuous improvement of the enhancing of performance, road quality, automobile driving speed is also improving constantly, yet traffic accident occurs also to become more frequent.In numerous traffic accidents, the manned vehicle commercial vehicle/comm..vehicle that knocks into the back occupies sizable a part of ratio.At home and abroad commercial vehicle/comm..vehicle all can be forced to install rear portion collision prevention girders additional before dispatching from the factory at present, prevents the manned vehicle commercial vehicle/comm..vehicle afterbody that knocks into the back.But American Highway security insurance association (IIHS) further investigation reveals that in the recent period; in numerous traffic accidents; the manned vehicle commercial vehicle/comm..vehicle that knocks into the back can cause higher fatal rate conventionally; and this kind of accident easily makes us ignoring truck afterbody defect in design; be the acceleration/accel that rigidly connected collision prevention girders can not effectively reduce manned vehicle in collision process, and it is very big to be rigidly attached to the possibility of the A post that destroys manned vehicle in collision process.Just, recently, IIHS has carried out simulation test to this type of accident.Result shows: if the collision prevention girders of the commercial vehicle/comm..vehicle tailstock is severed, the destroyed probability of manned vehicle A post improves, riding passenger's life security will face great threat, and particularly, in 30% and 50% rear-end collision, the effect that commercial vehicle/comm..vehicle tail defense device plays allows of no optimist.Although GB has relevant requirement to the vehicle back protector of commercial vehicle/comm..vehicle and towed vehicle, from actual accident conditions, this standard is not in step with the times, and the reasonableness of this device and science also doubtful.Once and there is this type of accident, particularly, under higher speed per hour, tend to make manned vehicle occupant to be subject to very serious injury.Therefore, in the urgent need to a kind of crash acceleration commercial vehicle/comm..vehicle afterbody anticollision mechanism that slows down.
For the commercial vehicle/comm..vehicle tailstock existing in prior art, be rigidly connected dangerous large, the art is needed badly and is wanted a kind of new production facilities to change this kind of present situation.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of commercial vehicle/comm..vehicle afterbody anticollision mechanism is provided, can solves the technical matters that commercial vehicle/comm..vehicle rear end collision is large.
A kind of commercial vehicle/comm..vehicle afterbody anticollision mechanism, it is characterized in that: comprise hydraulic spring grease cup, hanger, electronic control spring, collision prevention girders, energy-absorption box, hydraulic spring grease cup direction is vertical with ground surface, one end is bolted in collision prevention girders, the other end is connected with hanger by lock pin, and described hanger is connected to commercial vehicle/comm..vehicle car bottom; Described electronic control spring is parallel with ground surface, vertical with collision prevention girders, and one end is bolted in collision prevention girders, and the other end is connected with hanger by lock pin, and described hanger is connected on commercial vehicle/comm..vehicle crossbeam; Described energy-absorption box one side is connected with collision prevention girders, and opposite side is connected with car body.
Described hydraulic spring grease cup quantity is four.
Described electronic control spring quantity is two.
Described collision prevention girders is shaped as oblong, and bottom surface is inclined-plane; Collision prevention girders centre portion hollow out; Collision prevention girders length is 180 centimetres.
By above-mentioned design plan, the utility model can bring following beneficial effect:
1, the energy-absorption box of commercial vehicle/comm..vehicle afterbody anticollision mechanism of the present utility model, automatically controlled damping can increase collision time, reduce crash acceleration, transfer collision to flexible process by rigidity process.2, the collision prevention girders inclined design in commercial vehicle/comm..vehicle afterbody anticollision mechanism of the present utility model can increase the area of contact of manned vehicle and commercial vehicle/comm..vehicle, effectively protects manned vehicle personnel.3, commercial vehicle/comm..vehicle afterbody anticollision mechanism of the present utility model can carry out actv. repacking on original commercial vehicle/comm..vehicle afterbody rigidity anticollision mechanism basis, and its modification difficulty is little, cost is not high, repacking is convenient.4, commercial vehicle/comm..vehicle afterbody anticollision mechanism of the present utility model has good application, and its market outlook are very extensive, are suitable for traffic transport industry and apply.
