Problems solved by technology

Because the anti-collision beam of this structure is composed of a single rod, the contact area with the front of the trolley is small, and the anti-collision structure is not equipped with a buffer energy-absorbing device, and the energy-absorbing effect is not ideal due to the hollow steel pipe only. , will increase the damage of the car and the personal injury of the members in the car, threatening the safety of life
When a small car collides with a large truck from the side, the supporting structure of the anti-collision beam on the side of the truck is easily damaged, which cannot effectively prevent the small car from getting into the chassis of the truck. If the speed is too fast, it is easy to cause the car to crash

Embodiment Construction

[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0036] like figure 1 As shown, the side impact buffering and energy-absorbing device for a truck includes a wave-shaped energy-absorbing baffle 1 , a supporting energy-absorbing filling cylinder 4 , a fixing plate 3 and a tapered prism energy-absorbing bracket 5 . A concave cylindrical surface 14 is stamped on the back panel 7 of the wave-shaped energy-absorbing baffle 1 , and a bolt hole 15 is opened in the concave cylindrical surface 14 , which is connected with the supporting energy-absorbing filling cylinder 4 . The other side of the supporting energy-absorbing filling cylinder 4 is connected with the fixed plate 3, and the fixed plate 3 is connected with the tapered prism energy-absorbing support 5 with bolts. The other end of the conical prism energy-absorbing bracket 5 is tilted and connected to the frame of the truck, so that the whol...

Abstract

The invention discloses an anti-collision buffer energy-absorbing device for a side of a truck. The anti-collision buffer energy-absorbing device comprises a wave type energy-absorbing retainer plate, two energy-absorbing supporting filling barrels, tapered prism energy-absorbing supports and fixing plates. The wave type energy-absorbing retainer plate is far away from the outer side of a truck frame. The energy-absorbing supporting filling barrels act functions of fixing and connection in the middle and can absorb energy. The whole device is connected to the truck frame through the tapered prism energy-absorbing supports. The energy-absorbing supporting filling barrels are connected with the tapered prism energy-absorbing supports through the fixing plates. With the anti-collision buffer energy-absorbing device, when a small vehicle crashes into the side of the truck, more huge energy from the crash can be absorbed, initial peak stress of the crash of the small vehicle is decreased, the small vehicle is prevented from crashing into the bottom of the truck, and crash injuries of passengers in the small vehicle are reduced.

Description

technical field [0001] The invention relates to an automobile anti-collision device, more specifically, relates to a side anti-collision buffer energy-absorbing device for a truck, which is mainly suitable for a side energy-absorbing anti-collision structure of a large truck, and prevents small cars such as cars from colliding into a large truck from the side. Background technique [0002] With the continuous development of automobile technology and the increase of car ownership. People's requirements for the safety of all kinds of cars are also increasing. On the road, there are frequent accidents of small cars crashing into the chassis of large trucks, which also highlights that the safety of large trucks needs to be developed. At present, anti-collision mechanisms such as anti-collision beams are installed on the side of large trucks, but most of the anti-collision beams are hollow tubular structures, and the pipes are welded into well-shaped anti-collision brackets, whi...
