Description
Technical field
The present invention relates to field of traffic safety, and in particular to a kind of anti-collision device for automobile, anti-collision system and automobile.
Background technique
In daily traffic accident, the accident of vehicle collision or vehicle and rail collision frequent occurrence.When automobile and its
When his automobile crash, because the kinetic energy of vehicle cannot decompose, energy is all absorbed by collision object, will cause the serious of automobile
Deformation, causes great personnel casualty accidents；It such as collides with guardrail, it is run-off-road or pour opposite lane to hit the guardrail that collapses
Cause more serious consequence.Therefore collision prevention girders are installed to be protected on automobile head in the prior art, but current anticollision
Girder construction is fairly simple, is made of substantially girder steel and protective plate, and girder steel is connect with protective plate, then protective plate is mounted on vehicle head
Portion can only play certain anticollision, energy-absorbing effect, and when accidents occur, existing collision prevention girders are only capable of inhaling by Passive deformation
Receive energy, the energy that it is absorbed is impacted the influence of position, impact strength, crash direction, and the energy absorbed is also limited
, huge kinetic energy makes that rolling occurs for vehicle, rotation causes even more serious secondary accident to happen occasionally because cannot discharge,
In addition existing collision prevention girders must be frontal impact just effective energy-absorbing, but in traffic accident frontal impact chance it is very little.
With the development and use of new-energy automobile, for the tail portion of new-energy automobile (such as automobile of fuel cartridge postposition)
Collision prevention function is required, the Chinese patent of Publication No. CN108556775A discloses a kind of new-energy automobile in the prior art
Anticollision device, collision-prevention device, including automobile chassis, the installed in front of automobile chassis have the first detection device, and is equipped on rear side of automobile chassis
Two detection devices, automobile chassis are rotatably connected to attachment base by rotating mechanism, and attachment base is connected with anticollision by clamping mechanism
Bucket.Although the patent, in car crass, Anti-collision barrel is rotated by rotating mechanism, to be carried out to decompose impact force
Anticollision, but the Anti-collision barrel is connected on attachment base by clamping mechanism, is equivalent to rotatable cantilever beam, impact resistant capability compared with
Difference, and do not combine collision prevention girders mechanism with the mechanism of Anti-collision barrel, so that structure is complicated for anticollision device, collision-prevention device.
