It is connected on chassis runner, the other end is connected with collision prevention girders girder, every kind of energy-absorption box has the impact force License Value of itself, works as shock
When power is less than or equal to License Value, energy-absorption box can absorb whole Impact energies by the crumple of itself, in addition to energy-absorption box,
Other parts will not be damaged, and particularly, Impact energy can be avoided to be delivered to chassis runner, and chassis runner will not deform,
Thus after the low speed collision, chassis runner does not deform, it is not necessary to keep in repair, and greatly save cost；When impact force is more than
During License Value, energy-absorption box can absorbing impact energy to the full extent, reduction is delivered to the energy of chassis runner and other parts
Amount；It follows that the energy of the longer absorption of the length of energy-absorption box is also more, but due to the restriction of body shape, it is impossible to do
It is long, therefore, the energy-absorbing effect that energy-absorption box how is improved in unit length is the emphasis of the energy absorption ability for improving energy-absorption box.
Utility model content
To solve above-mentioned technical problem, this utility model provides a kind of energy-absorbing effect that energy-absorption box is improved in unit length
Vehicle energy absorption box.
This utility model is adopted the following technical scheme that：
A kind of vehicle energy absorption box, including energy-absorbing box body, tubular structure of the energy-absorbing box body for both ends open are described
Before energy-absorbing box body includes that the first energy-absorption box and the second energy-absorption box, first energy-absorption box are detachably arranged in the second energy-absorption box
End, the thickness of first energy-absorption box are less than the thickness of the second energy-absorption box, and this utility model is in common the first energy-absorption box of automobile
On the basis of, in front end plus detachable yielding second energy-absorption box, when the dynamics of collision is less, the energy of collision is variable
Second energy-absorption box of shape absorbs, and the first energy-absorption box will not deform, only need the second energy-absorption box of dismounting and change, substantially reduce dimension during maintenance
Accomplish this.
Preferably, the length of first energy-absorption box makes the length of integral energy-absorbing box exist less than the length of the second energy-absorption box
In the range of regulation.
Preferably, energy-absorbing groove is provided with first energy-absorption box and the second energy-absorption box, guiding energy-absorption box deforms to inhale
Receive collision energy.
Preferably, S type buffer boards are additionally provided with the energy-absorption box, the S types buffer board is stamping parts, increases energy-absorption box
The energy intensity of absorption.
Preferably, height of the height of the S types buffer board less than the second energy-absorption box, when the energy of collision is sufficiently large,
Deform the first energy-absorption box after the deformation of second energy-absorption box, after collision energy is transferred to S type buffer boards, the intensity of S type buffer boards
It is enough big, collision energy can be prevented to make the first energy-absorption box continue deformation, it is ensured that chassis runner will not deform, thus collide in higher speed
Afterwards, chassis runner does not also deform, it is not necessary to keep in repair, and greatlys save cost.
The beneficial effects of the utility model：
(1) when low speed collision, the dynamics of collision is less, and the energy of collision is absorbed by yielding second energy-absorption box, the
One energy-absorption box will not deform, and only need the second energy-absorption box of dismounting and change, substantially reduce maintenance cost during maintenance.
(2) when higher speed is collided, the energy of collision is sufficiently large, deforms the first energy-absorption box after the deformation of the second energy-absorption box,
After collision energy is transferred to S type buffer boards, the intensity of S type buffer boards is big, and collision energy can be prevented to continue the first energy-absorption box
Deformation, it is ensured that chassis runner will not deform, thus in higher speed collision rift, chassis runner does not also deform, it is not necessary to keep in repair, and
Greatly save cost.
Description of the drawings
Accompanying drawing is used for providing further understanding to of the present utility model, and constitutes a part for description, with this practicality
New embodiment is used for together explaining this utility model, does not constitute to restriction of the present utility model.In the accompanying drawings：
Fig. 1 is a kind of structural representation of vehicle energy absorption box of this utility model as schemed.
It is labeled as in figure：1st, energy-absorbing box body；11st, the first energy-absorption box；12nd, the second energy-absorption box；3rd, S types buffer board.
Specific embodiment
Specific embodiment of the present utility model is described below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of vehicle energy absorption box of the present utility model, including energy-absorbing box body 1, energy-absorbing box body 1 is two
The tubular structure of end opening, energy-absorbing box body 1 include the first energy-absorption box 11 and the second energy-absorption box 12, and the second energy-absorption box 12 is detachable
Be arranged at 11 front end of the first energy-absorption box, the thickness of the thickness of the second energy-absorption box 12 less than the first energy-absorption box 11, this utility model
On the basis of common the first energy-absorption box of automobile, in front end plus detachable yielding second energy-absorption box, when the power of collision
Degree is less, and the energy of collision is absorbed by yielding second energy-absorption box, and the first energy-absorption box will not deform, and need to only be dismantled more during maintenance
The second energy-absorption box is changed, maintenance cost is substantially reduced, the length of the second energy-absorption box 12 is made whole less than the length of the first energy-absorption box 11
The length of vehicle energy absorption box within the limits prescribed, is provided with energy-absorbing groove 2 on the first energy-absorption box 11 and the second energy-absorption box 12, draws
Lead energy-absorption box to deform to absorb collision energy.
