Description
Technical field
The utility model relates to a kind of Vehicular device, in particular to a kind of anti-collision beam energy absorbing box.
Background technique
With the continuous improvement that scientific and technological level fast development and people live, more and more various kart are as fortune
Defeated and walking-replacing tool enters huge numbers of families, but the following traffic accident is also gradually increasing.Various miniaturization automobiles
How when crashing, the safety of occupant is protected to the maximum extent, and reduce automobile important component as far as possible
Damage, loss is preferably minimized, it has also become the direction that each auto vendor makes great efforts.Front anti-collision beam is the main security portion of automobile
Part, energy-absorbing effect of the front anti-collision beam structure in head-on crash are the important measurement indexs of vehicle safety performance.Before energy-absorption box is
The main absorption cell of anticollision girder construction, energy-absorbing box structure directly affect the energy-absorbing and conquassation amount of energy-absorption box.2006, the U.S. and Europe
Continent proposes RCAR low speed collision requirement respectively, it may be assumed that automobile is when occurring low speed collision, in addition to absorb certain energy to guarantee
It outside passengers inside the car do not come to harm, while also requiring not damaging automobile longitudinal girder and other front-end geometry parts, such as front and back headlight, water
Case, squab panel etc. reduce loss to reduce auto repair expense.
Such as application No. is the patents of CN201420529411.5 to disclose a kind of body of a motor car energy-absorbing box structure, the energy-absorption box
Yield strength is low, is flexible structure, is constructed using cell compartment.When low speed collision occurs, effectively inhaled by the crumple of energy-absorption box axial direction
Energy when low speed impact is received, impact force is alleviated.But this kind of energy-absorption box is since stiffness by itself is little, so colliding in high speed
When, energy-absorbing is weak, crumple form is unstable, either all cannot achieve preferable protection to car body stringer or passenger.Separately
Outside, which kind of collision no matter occurs, which can all occur part and deform, must be replaced in maintenance process, increase dimension
Accomplish this.
Utility model content
The purpose of this utility model is just to provide a kind of anti-collision beam energy absorbing box, is not only simple in structure dimension practical, easy to disassemble
It repairs, mitigate collision prevention girders self weight, moreover it is possible to more energy be absorbed by stable crumple deformation when high speed collision occurs for automobile.
The purpose of this utility model is achieved in that a kind of anti-collision beam energy absorbing box, and the cross section of box body is in " day " font
Cavity configuration, along at the external angle in box body mold cavity axis direction be equipped with collapsing structure.
In the present invention, the cross section of box body is in " day " font cavity configuration, increases stiffness by itself；And along box body
Collapsing structure is equipped at the external angle in mold cavity axis direction, in high speed collision, energy-absorbing is weak, crumple form is unstable, to vehicle
Body stringer and passenger can realize preferable protection.
When in use, along vehicle direction of advance, it is divided into the two energy-absorbing cartridges in left and right；Energy-absorption box front end and collision prevention girders are horizontal
Beam is welded or is bolted on together, and rear end is welded or is bolted on collision prevention girders connecting plate side together, is prevented
The stringer for hitting the beam connecting plate other side and vehicle body connects.In the event of a collision accident, collision prevention girders meeting when being hit
It is expressed to energy-absorption box, because the major function of energy-absorption box is energy-absorbing, compressive deformation energy-absorbing energy can be carried out with impact force,
Energy-absorption box entire in this way can absorb collision energy to greatest extent.
By adopting the above-described technical solution, the utility model have the advantage that be not only simple in structure it is practical, be convenient for
Dismounting maintenance, mitigation collision prevention girders self weight, moreover it is possible to more by stable crumple deformation absorption when high speed collision occurs for automobile
Energy.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples:
As shown in Figures 1 to 4, the cross section of a kind of anti-collision beam energy absorbing box, box body 1 is in " day " font cavity configuration, along box
Collapsing structure is equipped with outside the axis direction of 1 type chamber of body at angle.
In the present invention, the cross section of box body is in " day " font cavity configuration, increases stiffness by itself；And along box body
Collapsing structure is equipped at the external angle in mold cavity axis direction, in high speed collision, energy-absorbing is weak, crumple form is unstable, to vehicle
Body stringer and passenger can realize preferable protection.
When in use, along vehicle direction of advance, it is divided into the two energy-absorbing cartridges in left and right；Energy-absorption box front end and collision prevention girders are horizontal
Beam is welded or is bolted on together, and rear end is welded or is bolted on collision prevention girders connecting plate side together, is prevented
The stringer for hitting the beam connecting plate other side and vehicle body connects.In the event of a collision accident, collision prevention girders meeting when being hit
It is expressed to energy-absorption box, because the major function of energy-absorption box is energy-absorbing, compressive deformation energy-absorbing energy can be carried out with impact force,
Energy-absorption box entire in this way can absorb collision energy to greatest extent.
Further, as shown in Fig. 2, being equipped with spring 2 inside box body 1.Specifically, spring 2 can be embedded in the inner wall of box body 1
On, it can also be adhesive on 1 inner wall of box body, quantity is 1 or 1 or more.In the event of a collision accident, collision prevention girders
