Abstract

The utility model discloses a collision protection device of small sized automobile in rear impact, comprising a support connector and an anticollision beam connected with one end of the support connector. The other end of the support connector is provided with a connector used for connecting with the bearing beam of the tail part of the large truck. After being connected, the anticollision beam is arranged under the tail of the large truck. The outer side of the anticollision beam is provided with an elastic body and a reflecting material layer. After the assembly is arranged under the tail part of the large truck, the exorbitant space to the ground between the bottom part of the cargo tank and the rear wheel is eliminated. After the car collides the tail part of the large truck, the head part of the car is collided under the interception of present assemble. Consequently, the self safety arrangement of the car is started. The car can not pierce the bottom of the truck. The driver can avoid colliding with the rigidity base plate in the bottom of the truck tank. Thus, present assembly can prevent the driver of the small sized automobile getting unnecessary damage. The added elastic body can enhance the safety further; the reflecting material has the obvious reminding function and active safe function.

Description

The compact car anti-collision protection device that knocks into the back

[technical field]:

The utility model relates to a kind of automobile anti-collision protective device, particularly a kind of compact car that is used for high capacity waggon anti-collision protection device that knocks into the back.

[background technology]:

Progress along with society, the vehicle of road driving is geometric growth, traffic accident is constantly risen, and has become social first harm, and it causes heavy losses for the lives and properties of human society, and in all traffic accidents, causing unnecessary damages to cause the traffic accident of personal casualty is exactly compact car, because the speed of a motor vehicle is fast, tired driver is driven, brake is anxious, knocks into the back to bump against the high capacity waggon afterbody and cause casualties.

Present all compact car security protection systems; quite perfect (as the ABS brake system; safety air bag; the plastic deformation design of driving engine case lid etc.); why still do not protect; its basic reason is that the high capacity waggon moving velocity is slow; afterbody container ground clearance height; and container bottom to trailing wheel space length just is the distance that the compact car engine bangs into; when the compact car following distance is crossed nearly generation emergency situation; when in case the compact car rear-end collision takes place; compact car will " pierce " the high capacity waggon bottom; the security protection system of compact car can't start the safety of protecting the compact car driver and conductor, and (safety air bag need clash into and could start; the plastic deformation design of driving engine case lid also is just to work after being bumped against); also just can't reach the purpose of safety precaution; so that cause the unnecessary damages to the driver and conductor: after compact car " pierced " the high capacity waggon bottom, lorry bottom rigidity base plate just in time " switched to " driver and conductor's chest or head.

[summary of the invention]:

The purpose of this utility model is exactly in order to overcome the above problems, and a kind of compact car anti-collision protection device that knocks into the back is provided.

For achieving the above object; the utility model proposes a kind of compact car anti-collision protection device that knocks into the back; it is characterized in that: comprise support connecting piece and the collision prevention girders that links to each other with the one end; the other end of described support connecting piece has connecting device; be used for linking to each other with the container bearing beam of truck afterbody, the described collision prevention girders in back that links to each other is positioned at truck afterbody below.

The outside in described collision prevention girders also is provided with elastic body, and reflective material layer.

Adopt the beneficial effect of above scheme: after this device is contained in the afterbody below of truck, eliminated its container bottom to the liftoff too high space of this section of trailing wheel.After roadlice knocked its afterbody, under the interception of this device, the head of roadlice was hit, thereby started the safety guard of roadlice self; And dolly also can't pierce the lorry bottom, and the driver and conductor is avoided bumping against with the rigidity base plate of truck body bottom.Therefore this device can protect the compact car driver and conductor to be subjected to unnecessary damages.

The elastic body of setting up can further strengthen safety; And reflex-reflective material is mentioned tangible reminding effect, has the effect of active safety.

[specific embodiment]:

Also in conjunction with the accompanying drawings the utility model is described in further detail below by specific embodiment.

Embodiment one:

Shown in Fig. 1-7; this anti-collision protection device; the support connecting piece 1 and the collision prevention girders 2 that links to each other with the one end that comprise two arcs; the other end of described support connecting piece 1 has mounting hole 11; be used for linking to each other with the container bearing beam of truck afterbody (this bearing beam generally is a U-lag steel of laying across), the described collision prevention girders 2 in back that links to each other is positioned at truck afterbody below.Scheme drawing after the installation is shown in Fig. 5,6,7, and this anti-collision protection device just in time is positioned at the blank position that roadlice is easy to knock into the back and pierces, but it can not reduce the chassis height of lorry again, because it is loaded on the railway carriage, the railway carriage bottom is original just than chassis height.

In this example, described support connecting piece 1 was realized with being connected by mounting screw 5 of collision prevention girders 2.But described support connecting piece 1 can be directly one-body molded as a whole with described collision prevention girders 2.

In order further to strengthen protective value; the outside in described collision prevention girders also is provided with elastic body 3; described elastic body 3 is made for automotive wheels periderm (generally using junked tire), and corresponding is the shaped steel that has groove in described collision prevention girders, so that the hot pressing of automotive wheels periderm is embedded in the groove of described shaped steel.Though can adopt other elastomeric materials at elastic body 3, adopt the junked tire regeneration can solve a great problem of junked tire contaminated environment simultaneously.

Present embodiment also has reflective material layer 4 in described collision prevention girders 2 outsides, so that the automobile of back or pedestrian can be more clearly visible this lorry, improves the active safety performance of back car.This reflective material layer 3 can directly not be coated on the collision prevention girders 2 when having elastomeric material, just is coated on the elastomeric material when flexible material.It can be local coating, also can be decorative pattern shape coating.

Described mounting hole 11 also can change other connecting devices into, such as screw, weld zone etc. (when adopting welding manner, described connecting device just is meant that the end of support connecting piece 1 is fit to the position of welding with the lorry afterbody, is called for short weld zone).

The quantity of the support connecting piece 1 of arc can be set as required.If the expanded letter cart can increase its quantity.

Embodiment two:

Shown in Fig. 8-11, in this example, support and connection body 1 adopts up big and down small shape, can increase the width of it and lorry afterbody connecting portion like this, so that connect more firmly, is not easy to come off when being subjected to clashing into.

Embodiment three:

Shown in Figure 12-15, set up strength beam 6 in this example, its end links to each other with support and connection body 1, and the other end links to each other with collision prevention girders 2, has further strengthened the impact resistance performance.When support and connection body 1 had two, strength beam 6 also was provided with two, was respectively applied for to strengthen each support and connection body, and generally speaking, they should symmetry be provided with, as this example.
