Description
Technical field
The utility model belongs to automobile collision preventing construction applications, and in particular to a kind of automotive front anti-collision structure.
Background technology
At present, existing automotive front anti-collision structure（Referring to this specification accompanying drawing 1）Including automobile front beam 1, anticollision
Beam 2 and padded coaming 3（For example, foamed material）, automobile front beam 1 is bolted at the two ends of vehicle-body width direction
On car body, pad sets and is fixedly connected with padded coaming 3 between the rear side of automobile front beam 1 and the front side of collision prevention girders 2.Collision prevention girders
Rear side is fixedly mounted on the longeron of vehicle frame by the energy-absorption box on rear side of its length direction two ends（Referring to this specification accompanying drawing 2
（Notification number is CN106043183A, the structural representation of entitled " front anticollision beam of automobile assembly "）, wherein, label 100 is anticollision
Beam, label 102 is energy-absorption box）.
But above-mentioned automotive front anti-collision structure still has following weak point：
There is low speed collision（Travel speed before car crass is in below 10km/h）When, above-mentioned padded coaming 3 can
It is right（Plastic material）Front bumper 1 plays a cushioning supportive, reduces impact wreckage power, so as to reduce collision to front bumper
1 damage, reduces maintenance cost.
But there is middling speed collision（Travel speed before car crass is in 20km/h to 40km/h）When, automobile driver
Still can be very safe under the protective effect of safety belt and air bag.But automobile front beam 1 can be fast with padded coaming 3
Fast damage, and remaining impact all undertakes and crumple energy-absorbing by collision prevention girders and energy-absorption box, and occur collision prevention girders with
And after energy-absorption box crumple, the maintenance cost of automobile can be raised drastically（It is thousands of or even up to ten thousand）, brought to autoist larger
Financial burden.
Based on this, applicant considers that design one kind can be when automobile meets with middling speed and collides, and anticollision effect is good, lowers vapour
Car damaged degree, so as to reduce the installation structure for automotive front bumpers of maintenance cost.
The content of the invention
For above-mentioned the deficiencies in the prior art, technical problem to be solved in the utility model is：How a kind of energy is provided
Enough when automobile meets with middling speed and collides, anticollision effect is good, lowers automobile damaged degree, so that before reducing the automobile of maintenance cost
