Abstract
The invention relates to a bumper with a buffering structure. The bumper comprises a transverse beam, buffer plates, elastic bodies and connecting seats, wherein the transverse beam is arranged along the width direction of an automobile; energy absorbing boxes are arranged on the two end parts of the transverse beam along the longitudinal direction of the automobile; the two ends of the buffer plates extend along the width direction of the automobile; the buffer plates are fixed on the surface, which faces an automobile body, of the transverse beam; the buffer plates are provided with at least two bumps facing the automobile body; the surfaces, facing the transverse beam, of the bumps are not in contact with the transverse beam; one end of each elastic body is fixed on the surface, which faces away from the transverse beam, of each bump; the other ends of the elastic bodies are fixedly connected with the connecting seats. When the transverse beam is collided, the collision acting force can be transferred onto the energy-absorbing boxes in time, so that the collision acting force among colliders is reduced.
Description
Technical field
The present invention relates to the protective device on a kind of car body, be specifically related to a kind of bumper/spoiler with buffer structure.
Background technology
Bumper damper meets study plot in the car and is arranged on front and rear side, to absorb the collision energy of less collision process, thus does not damage the supporting structure of of automobile itself as much as possible.Bumper damper is made up of crossbeam usually, and it can be fixed transverse to the longeron of automobile frame when loading collision energy absorbing box.Crossbeam is used for, by importing in collision energy absorbing box by impacting the energy caused, being carried out changing and absorbing by collision energy there.
Although energy-absorption box can absorb energy in collision process, but for the assembly relation of energy-absorption box and crossbeam, energy-absorption box is two ends being assemblied in crossbeam, for such mounting structure, when crossbeam front is collided application force, colliding forces concentrates on the middle part of crossbeam, under transient state, colliding forces cannot be transferred to energy-absorption box by crossbeam rapidly, and the problem brought thus is, if application force is excessive, crossbeam will directly be damaged.
Summary of the invention
For above-mentioned technical matters, main purpose of the present invention is for providing a kind of bumper/spoiler with buffer structure, colliding forces, when crossbeam is collided, can be transferred to energy-absorption box by the present invention in time, reduces the colliding forces born between collision body thus.
There is the bumper/spoiler of buffer structure, comprise a crossbeam arranged along vehicle width direction, the energy-absorption box arranged along automobile longitudinal is provided with in two ends of crossbeam, also comprise dash plate, elastic body, Connection Block, the two ends of dash plate extend along the direction of vehicle width, dash plate be fixed on crossbeam towards on the face of car body, dash plate is at least provided with two projections to car body direction, this projection does not contact towards the surface of crossbeam with crossbeam, described elastomeric one end is fixed on and throws one's back out from the surface of crossbeam, the elastomeric other end is fixed on and is connected with Connection Block.
The shape of cross section of described crossbeam becomes U-shaped or C font.
Have employed such scheme, when crossbeam is collided application force, because the two ends of dash plate extend along the direction of vehicle width, dash plate be fixed on crossbeam towards on the face of car body, dash plate is at least provided with two projections to car body direction, this projection does not contact towards the surface of crossbeam with crossbeam, therefore, colliding forces is delivered to dash plate by crossbeam, under the elastic acting force of dash plate, application force disperses by dash plate, point an application force part can arrive energy-absorption box, undertaken absorbing and changing by energy-absorption box, on the other hand, force transmission throws one's back out from the elastic body on the surface of crossbeam to being connected to, undertaken absorbing and changing by elastic body, therefore, colliding forces can be transferred to energy-absorption box by the present invention in time, reduce the colliding forces born between collision body thus.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
1 is crossbeam, and 2 is energy-absorption box, and 3 is dash plate, and 4 is elastic body, and 5 is Connection Block, and 6 is protruding.
Detailed description of the invention
With reference to Fig. 1, the bumper/spoiler with buffer structure of the present invention, comprise a crossbeam 1 arranged along vehicle width direction, the shape of cross section of crossbeam becomes U-shaped or C font.The energy-absorption box 2 arranged along automobile longitudinal is provided with in two ends of crossbeam 1.Also comprise dash plate 3, elastic body 4, Connection Block 5.The two ends of dash plate 3 extend along the direction of vehicle width, dash plate 3 be fixed on crossbeam 1 towards on the face of car body, dash plate 3 is at least provided with two projections 6 to car body direction, this projection 6 does not contact towards the surface of crossbeam with crossbeam.One end of described elastic body 4 is fixed on protruding 6 and deviates from the surface of crossbeam, and the other end of elastic body 6 is fixed on and is connected with Connection Block 5.
Claims (2)
