Description

Buffer for preventing traffic collision of automobile

The utility model is a kind of mechanical cushioning device, the shock absorber when particularly a kind of automobile is collided.In the galloping, bump against suddenly, often cause the accident of car crash with the car collision of running at high speed in opposite directions or with fixed object such as building.Many even tens of the car traffic accidents of head and the tail collision continuously also can take place on express highway, can cause the very big loss of personnel and property like this.The not fine as yet solution on the existing various automobile of producing of this problem in the highway communication.Though, the bumper/spoiler of existing automobile chassis frame front end has certain mitigation effect to the automobile major part, the safety belt that the car dress circle is provided with also has certain mitigation effect to personnel, but can not more effectively reach the purpose of mitigation under pernicious collision condition.＜＜automotive body structure design＞＞one book (edit in yellow day pool, Jilin Industry University gold mound by Hunan University; China Machine Press in October, 1992 publishes) in the 16th page; protection occupant personal safety problem is analyzed; point out; for vertical collision; " at body forward structure with the rear portion is elastic construction and the middle part is under the situation of rigid construction, can guarantee occupant safety." this analysis is pointed; though there is the elastic construction at body forward structure and rear portion to play buffer action; because this two parts integral rigidity is still bigger; when colliding; backward acceleration is very big; the injury to the occupant is still more serious, again because the buffering when colliding realize by the forward and backward structure of vehicle body, must be that the destruction with this part is cost.

The purpose of this utility model is to provide a kind of automobile major part that can make when car collision to exempt from destruction, and the energy disperser that can avoid personal casualty again is an automobile car accident mitigation energy disperser.

The utility model is realized by following measures: the utility model be a kind of when being used for car collision automobile car accident mitigation energy disperser it comprise spring, it is characterized in that it also includes spring guide, hit plate 1 and supported the power transmission tube, this energy disperser is made up of the spring bumper of two kinds of models, a kind of model I that is called, a kind of model II that is called, spring 2,7 belong to the model I, spring 3,4,5,6 belong to the model II, spring guide 8,9,10,11,12,13 front end respectively with hit plate 1 and be connected, spring 2,3,4,5,6,7 are enclosed within spring guide 8 respectively, 9,10,11,12, on 13, the front end of all springs all withstands on and is hit on the plate 1, the spring 2 of model I, 7 rear end withstands on vehicle body engine room front portion, the spring 3 of model II, 4,5,6 rear end withstands on respectively supports power transmission tube 14,15,16,17 front end, support power transmission tube 14,17 rear end is connected with vehicle body engine room rear portion respectively, support power transmission tube 15,16 rear end is connected with vehicle body boot compartment front portion respectively, and 6 spring bumperes are parallel to the balanced configuration of the vehicle body longitudinal axis on every side around driving engine.Cushioning principle of the present utility model is, kinetic energy that automobile the had buffering of spring when bumping against is transformed into the elastic potential energy of spring.Because the mass M and the speed V of automobile are bigger, so the kinetic energy that the automobile in travelling has is very big, after colliding, the speed of a motor vehicle is in the very short time and vanishing in the very short distance, kinetic energy suddenly disappears, do not install at automobile under the situation of mitigation energy disperser, this part kinetic energy is absorbed the deformation energy that has converted automobile parts and housing to by automobile itself, this deformation is expendable, this deformation process is exactly the destructive process of automobile parts and housing, simultaneously, because backward acceleration is big especially, also be the process of following personal casualty.Had after the mitigation energy disperser, this kinetic energy no longer becomes the automobile deformation energy and changes into the elastic energy of spring series when car collision, has avoided the destruction of automobile parts and housing.The buffer action of spring makes and bumps against the in-service time lengthening, and corresponding tampering action distance widens, and backward acceleration then reduces greatly, thereby the suffered injury of occupant is alleviated greatly.Just can avoid the damage and the personal casualty of automobile major part fully as long as when design, select suitable spring stiffness, elastic force, spring number.

The utility model has been compared following usefulness with background technology: (1) avoids automobile major part such as driving engine to wreck.This is that vehicle frame and vehicle body suffered power in whole collision process is spring force all the time because when car collision, and major parts such as driving engine are not born the task of absorbing kinetic energy, do not produce permanent deformation, so can not destroyed.Because the spring force dispersing action is at each position of vehicle frame and vehicle body, so vehicle frame and vehicle body can not destroyed yet.(2) personnel avoid injures and deaths.Because the buffer action of spring has increased the tampering action distance, backward acceleration reduces greatly, and personnel's injury is avoided or alleviated.
