It belongs to the anti-collision component of the vehicle body and is one of the more important safety parts on the vehicle body. At the same time, since it belongs to a vulnerable product series, its quality and use have a direct impact on the safety performance of the vehicle; in the prior art The energy absorption box is an important blocking part of the anti-collision beam frame assembly. The energy absorption box is divided into two parts, a fixed end and a movable end. The interior of the energy absorption box is provided with energy absorbing components such as springs or buffer pads. When the car is hit, the impact force generated by the collision will cause the movable end and the fixed end to move relative to each other, and the energy absorbing components in the energy absorption box will deform.

The interior of rotating frame 1 32 is rotatably connected with rotating plate 1 33 through rotating shaft 1. The side of energy absorption box 31 is provided with rotating frame 36. The interior of rotating frame 36 is rotatably connected with energy absorption telescopic rod 34. The end of energy absorption telescopic rod 34 is rotatably connected with rotating frame 2 35. The rear end of rotating frame 2 35 and the rear end of rotating plate 1 33 are provided with mounting plate 2. The anti-collision beam frame assembly is connected to the vehicle through mounting plate 2. The energy absorption box 31 includes a first slide column 311, a sealing plate 312 and a box body 313. The rear end of the box body 313 is respectively provided with a rotating frame 32. The interior of the box body 313 is slidably connected with the sealing plate 312. The front surface of the sealing plate 312 is provided with a first slide column 311. The front ends of the first slide columns 311 pass through the interior of the box body 313 and are connected to the fixing plate 4. The sides of the box body 313 are respectively provided with a rotating frame 36. The energy absorption telescopic rod 34 includes a slide groove cylinder 341, a second slide column 343 and a connecting rotating plate 345. There are two slide groove cylinders 341 and they are distributed on the left and right. The interior of the slide groove cylinder 341 is slidably connected with the second slide column 343. The front end and the rear end of the slide groove cylinder 341 are both provided with a connecting rotating plate 345, the connecting rotating plate 345 on the rear side is rotatably connected to the rotating frame 2 35 through the rotating shaft 2, and the connecting rotating plate 345 on the front side is rotatably connected to the rotating frame 3 36 through the rotating shaft 3. The energy absorbing telescopic rod 34 also includes a spring 342, which is respectively arranged between the rear end of the second sliding column 343 and the rear inner wall of the slide groove cylinder 341, and the spring 342 fits the inner arc surface of the slide groove cylinder 341. The energy absorbing mechanism 3 also includes an air pipe 37, which is respectively arranged between the box body 313 and the slide groove cylinder 341, and the box body 313 and the slide groove cylinder 341 are respectively connected to the air pipe 37. When the car collides, When the collision position is in front of the anti-collision beam, the pressure generated by the collision will push the sealing plate 312 to slide in the box body 313. Affected by the exhaust speed of the air inside the box body 313, the compression of the air is used to block the backward movement of the sealing plate 312, thereby reducing the transmission of the impact to the car. At the same time, the air exhausted from the box body 313 will enter the rear end of the inner groove cylinder 341 through the air pipe 37, thereby increasing the air pressure inside the groove cylinder 341, pushing the second slide column 343 to slide forward inside the groove cylinder 341, and the energy absorbing telescopic rod 34 is extended, pushing the rotating plate 1 33 to rotate in the rotating frame 1 32, so that the energy absorbing box 31 tilts outward, dispersing the impact force to the left and right sides, thereby improving the buffering effect.When the collision position is at the side of the anti-collision beam, the impact force generated by the collision will cause the left and right ends of the main beam 1 to deform. Under the action of the collision impact force, the rotating plate 33 rotates in the rotating frame 32, causing the energy absorption box 31 to tilt inward. At this time, the energy absorption telescopic rod 34 contracts, and the impact force is buffered by the contraction of the spring 342, slowing down the transmission of the impact force to the car. At the same time, the air discharged from the chute cylinder 341 will enter the rear end of the box body 313, increasing the air pressure at the rear end of the box body 313, and more effectively blocking the transmission of the impact force. ;

[0022] The working principle of the anti-collision beam frame assembly of an automobile provided by the utility model is as follows: when in use, the anti-collision beam frame assembly is connected to the automobile through the mounting plate 2. When the automobile collides, when the collision position is in front of the anti-collision beam, the pressure generated by the collision will cause the main beam 1 to deform, and under the connection of the first slide column 311, the sealing plate 312 is pushed to slide in the box body 313. Affected by the exhaust speed of the air inside the box body 313, the compression of the air is used to block the backward movement of the sealing plate 312, thereby reducing the transmission of the impact to the automobile. At the same time, the air exhausted from the box body 313 will enter the inner rear end of the slide groove cylinder 341 through the air pipe 37, so that the air pressure inside the slide groove cylinder 341 increases, and the second slide column 343 is pushed inside the slide groove cylinder 341. Sliding forward, the energy-absorbing telescopic rod 34 extends, pushing the rotating plate 33 to rotate in the rotating frame 32, causing the energy-absorbing box 31 to tilt outward, dispersing the impact force to the left and right sides, and improving the energy absorption effect. When the collision position is on the side of the anti-collision beam, the impact force generated by the collision will cause the left and right ends of the main beam 1 to deform. Under the action of the collision impact force, the rotating plate 33 is rotated in the rotating frame 32, causing the energy-absorbing box 31 to tilt inward. At this time, the energy-absorbing telescopic rod 34 contracts, and the contraction of the spring 342 is used to buffer the impact force, thereby slowing down the transmission of the impact force to the car. At the same time, the air discharged from the slide groove cylinder 341 will enter the rear end of the box body 313, increasing the air pressure at the rear end of the box body 313, and more effectively blocking the transmission of the impact force.
