Abstract
The invention discloses a kind of high-performing car collision prevention girders, which includes: anticollision girder, mounting base and energy-absorption box, and anticollision girder is made of metal-rubber；Mounting base is connected by energy-absorption box with the inner edge of anticollision girder, and mounting base is capable of fixing the front end of automobile.The high-performing car collision prevention girders have excellent crashworthiness.
Description
Technical field
The present invention relates to automobiles, and in particular, to a kind of high-performing car collision prevention girders.
Background technique
Automobile as it is a kind of transport and walking-replacing tool use it is more more and more universal, but thereupon traffic accident also increasing year by year
Add, security performance has become one of important quality index of Hyundai Motor.Guarantee the safety of occupant to greatest extent, reduce automobile
The damage of important component becomes the direction that each producer makes great efforts, and low speed collision is even more to mention to auto-safety mechanism, especially collision prevention girders
Tightened up requirement out.When positive collision occurs for automobile, front anti-collision beam can reduce the impaired of vehicle body and occupant, and then reduce
Maintenance cost and the safety for protecting vehicle and passenger.
Automobile buffer beam setting collides the damage caused by vehicle body for buffering front in automotive front end, and then protects and drive
The personal safety of member and passenger.Existing collision prevention girders are made of steel, aluminium alloy, the mutability in car crass, crashworthiness
It can be lower.
Summary of the invention
The object of the present invention is to provide a kind of high-performing car collision prevention girders, which prevents with excellent
Hit performance.
To achieve the goals above, the present invention provides a kind of high-performing car collision prevention girders, including anticollision girder, mounting base
And energy-absorption box, anticollision girder are made of metal-rubber；Mounting base is connected by energy-absorption box with the inner edge of anticollision girder, mounting base
It is capable of fixing the front end of automobile.
Preferably, anticollision girder is the bends of evagination.
Preferably, energy-absorption box is four sides gauffer energy-absorption box.
Preferably, energy-absorption box is distributed in the both ends of anticollision girder.
In the above-mentioned technical solutions, the principle of high-performing car collision prevention girders provided by the invention is as follows: metal-rubber has
With preferable elasticity, biggish damping；Anticollision girder is generated using metal-rubber material by intermetallic Relative sliding
Dry friction achievees the effect that vibration damping, while the porosity of metal-rubber can also inhale to a certain extent to consume vibrational energy
Receive the energy generated when hitting；When automobile is collided, anticollision girder and the common shock-absorbing of energy-absorption box reduce collision to vehicle body
It destroys, while can recycled by replacement collision prevention girders girder realization after multiple impacts, after multiple impacts,
The device for needing to renew directly is removed when needing repairing.Anticollision girder provides certain support stiffness to car body simultaneously.
In addition, metal-rubber is not affected by environment, more many than common rubber long service life times, while having certain intensity, energy again
Vibration, the deformation that complicated collision generates are adapted to, using the difference of metal-rubber density, difference can be obtained in particular manner
The collision prevention girders of damping characteristic adapt to the demand of different automobiles, convenient for disassembly and assembly, good anti-vibration.
Other features and advantages of the present invention will the following detailed description will be given in the detailed implementation section.
Detailed description of the invention
The drawings are intended to provide a further understanding of the invention, and constitutes part of specification, with following tool
Body embodiment is used to explain the present invention together, but is not construed as limiting the invention.In the accompanying drawings:
Fig. 1 is the structural schematic diagram of the preferred embodiment of high-performing car collision prevention girders provided by the invention.
Description of symbols

3, anticollision girder
Specific embodiment
Below in conjunction with attached drawing, detailed description of the preferred embodiments.It should be understood that this place is retouched
The specific embodiment stated is merely to illustrate and explain the present invention, and is not intended to restrict the invention.
In the present invention, in the absence of explanation to the contrary, the noun of locality that " inside and outside " etc. is included in the term only represents
Orientation of the term under normal service condition, or be those skilled in the art understand that be commonly called as, and be not construed as to the term
Limitation.
The present invention provides a kind of high-performing car collision prevention girders, as shown in Figure 1, including anticollision girder 3, mounting base 1 and suction
Energy box 2, anticollision girder 3 are made of metal-rubber；Mounting base 1 is connected by energy-absorption box 2 with the inner edge of anticollision girder 3, installation
Seat 1 is capable of fixing the front end of automobile.
The principle of above-mentioned high-performing car collision prevention girders is as follows: metal-rubber is with preferable elasticity, biggish resistance
Buddhist nun；Anticollision girder 3 consumes vibrational energy by the dry friction that intermetallic Relative sliding generates using metal-rubber material,
Achieve the effect that vibration damping, while the energy that when porosity of metal-rubber also can absorb shock to a certain extent generates；Work as vapour
When vehicle is collided, anticollision girder 3 and the common shock-absorbing of energy-absorption box 2 reduce destruction of the collision to vehicle body, while by repeatedly touching
It can be recycled by replacement collision prevention girders girder realization after hitting, after multiple impacts, directly removing when needing repairing is needed
The device to be renewed.Anticollision girder 3 provides certain support stiffness to car body simultaneously.In addition, metal-rubber is not by ring
Border influences, and more many than common rubber long service life times, while having certain intensity again, adapt to the vibration that complicated collision generates
Dynamic, deformation, using the difference of metal-rubber density, can obtain the collision prevention girders of different damping characteristic in particular manner, fit
Answer the demand of different automobiles, convenient for disassembly and assembly, good anti-vibration.
In the present invention, the concrete shape of anticollision girder 3 can select in a wide range, but in order to further increase
The crashworthiness of anticollision girder 3, it is preferable that anticollision girder 3 is the bends of evagination.
In the present invention, the type of energy-absorption box 2 can select in a wide range, but in order to further increase energy-absorption box
2 shock-absorbing effect, it is preferable that energy-absorption box 2 is four sides gauffer energy-absorption box.
In the present invention, 2 distributing position of energy-absorption box can select in a wide range, but in order to further increase energy-absorbing
The shock-absorbing effect of box 2, it is preferable that energy-absorption box 2 is distributed in the both ends of anticollision girder 3.
It is described the prefered embodiments of the present invention in detail above in conjunction with attached drawing, still, the present invention is not limited to above-mentioned realities
The detail in mode is applied, within the scope of the technical concept of the present invention, a variety of letters can be carried out to technical solution of the present invention
Monotropic type, these simple variants all belong to the scope of protection of the present invention.
It is further to note that specific technical features described in the above specific embodiments, in not lance
In the case where shield, can be combined in any appropriate way, in order to avoid unnecessary repetition, the present invention to it is various can
No further explanation will be given for the combination of energy.
In addition, various embodiments of the present invention can be combined randomly, as long as it is without prejudice to originally
