Description
Technical field
The utility model belongs to auto body attachment technique field, specifically, relates to a kind of rear-end collision anticollision device.
Background technology
Continuous improvement along with road, Vehicle Speed has had large increase, the safety problem of dispatch driving has caused people's very big concern, particularly because the too fast rear-end collision accident that causes of the speed of a motor vehicle takes place comparatively frequent, especially at relatively poor environment of driving sight line such as sleet, mist weather and nights, the easier traffic accident that rear-end collision occurs causes the loss that can't retrieve for people's lives and properties.
At present, in order to reduce personal casualty and property damage, many producers install inflatable airbags at automobile rear end dress metal or plastic housing bumper/spoiler at automobile rear.At the front-end and back-end of automobile dress metal or plastic housing bumper/spoiler, though can the absorption portion energy when colliding, but,, often do not have automobile crashproof effect when fair speed so the absorption energy is less because it is to lean against the metal of bumper/spoiler when colliding or plastic deformation to come endergonicly.And the inflatable safety air bag is installed, it is violent shake when automobile takes place to collide or electrical automobile strong deformation and make the explosive inflation of safety air bag, makes driver and passenger obtain buffering when colliding, and reaches protection driver and passenger's purpose.Though this method has safe effect preferably, often the time lag of airbag opening is in the time that bumps, and the basis for estimation of sending airbag opening is difficult to accomplish accurately.
The utility model content
The present invention overcomes that above-mentioned safety air bag can not in time be opened and the basis for estimation of safety air bag is difficult to technical deficiencies such as accurate, and provides a kind of and can preestablish, effectively absorb collision energy when having an accident, in time carry out a kind of rear-end collision anticollision device of active protection.
Design of the present utility model is, a kind of rear-end collision anticollision device is provided with the tail part protection plate at the afterbody of automobile, and the tail part protection plate is connected with permanent seat by the tail part protection trailing arm, permanent seat is installed in the rear portion on automotive frame or chassis, and described permanent seat is connected with friction lining by the friction lining trailing arm; Wherein, the described permanent seat slide block that is provided with rail groove and in rail groove, slides; Described slide block connects the common ends of bar-spring, tail part protection trailing arm and friction lining trailing arm, and the other end of bar-spring is connected and fixed the end of seat, and the other end of described friction lining trailing arm connects friction lining.Described friction lining trailing arm is elastic element or stiffener.Described tail part protection trailing arm is a stiffener.Described friction lining trailing arm and friction lining are for captiveing joint.
A kind of rear-end collision anticollision device that the utility model adopts; when automobile generation rear-end collision, the tail part protection trailing arm of tail part protection plate by rigidity passes to slide block on the permanent seat with impact, and slide block is under the effect of impact; part compression bar-spring absorbs Impact energy.Another part passes to the friction lining trailing arm, because the friction lining trailing arm is an elastic element, compressive deformation absorbs Impact energy.In addition, the friction lining trailing arm is connected with the friction lining cliding friction, consumes collision energy in cliding friction.Friction lining is subjected under the effect of force of sliding friction, forces automobile to begin braking, consumes collision energy.If the friction lining trailing arm is a stiffener, more help increasing friction drag.Automobile is stopped within a short period of time, effectively avoid personal casualty.
A kind of rear-end collision anticollision device of the technical solution adopted in the utility model, it can preestablish, effectively absorb or transform a large amount of collision energies, in time carry out active protection when having an accident, and stopping distance is short, effectively avoids personal casualty.Simultaneously, it is simple that the present invention also has manufacturing process, easy for installation, characteristics such as long service life.
Description of drawings
In conjunction with the following drawings technical solutions of the utility model are further described;
Fig. 1 is a structural representation of the present utility model;
Wherein, the tail part protection plate 1; Tail part protection trailing arm 2; Permanent seat 3; Friction lining trailing arm 4; Friction lining 5; Slide block 6; Bar-spring 7.
The specific embodiment
As shown in Figure 1; the utility model provides a kind of rear-end collision anticollision device; afterbody at automobile is provided with tail part protection plate 1; described tail part protection plate 1 bonded assembly permanent seat 3; permanent seat 3 is installed in the rear portion on automotive frame or chassis; specifically be installed on the mounting bracket of rear bumper, described permanent seat 3 is connected with friction lining 5 by friction lining trailing arm 4.
When automobile generation rear-end collision, the tail part protection trailing arm of described tail part protection plate 1 by rigidity passes to slide block 6 on the permanent seat 3 with impact, and slide block 6 is under the effect of impact, and part compression bar-spring 7 absorbs Impact energy.Another part passes to friction lining 5 trailing arms, because friction lining 5 trailing arms are elastic element, compressive deformation absorbs Impact energy.In addition, friction lining 5 trailing arms are connected with friction lining 5 cliding frictions, consume collision energy in cliding friction.Friction lining 5 is subjected under the effect of force of sliding friction, forces automobile to begin braking, consumes collision energy.If friction lining 5 trailing arms are stiffener, more help increasing friction drag.Automobile is stopped within a short period of time, effectively avoid personal casualty
In the utility model, described tail part protection plate 1 is connected with permanent seat 3 by tail part protection trailing arm 2.The slide block 6 that described permanent seat 3 is provided with rail groove and slides in rail groove.Described slide block 6 connects the common ends of bar-spring 7, tail part protection trailing arm and friction lining 5 trailing arms, and the other end of bar-spring 7 is connected and fixed the end of seat 3, and the other end of described friction lining 5 trailing arms connects friction lining 5.
