Energy-absorbing and decompressing protective frame device installed on the rear frame of heavy-duty vehicles

Abstract

The invention provides an energy-absorbing and decompression protective frame device installed on the rear frame of a heavy-duty vehicle, comprising: a base plate, a rectangular plate C and a fixing seat; the front end of the base plate is provided with a rectangular groove; the cylindrical rod B is slidingly connected in the middle of the rectangular plate A and the rectangular plate B. The present invention has high safety. When the left side or the right side of the force plate is hit, the force plate can be rotated left or right along the position of the rotating connection seat, and the force plate can be rotated left or right. When turning to the right, the spring B on the cylindrical rod A can be compressed for shock absorption. At this time, the iron ball A on the cylindrical rod A can slide along the semicircular groove. When the force plate is under the action of the impact force When continuing to rotate, the iron ball A on the cylindrical rod A compresses the cylindrical rubber on the rectangular plate A to perform buffering and shock absorption again. Under the action of the impact, the force plate is inclined, and the impact force can be directed to the left or The force is unloaded on the right side to prevent the subsequent impact of the impact force.

Description

technical field [0001] The invention belongs to the technical field of automobile decompression protection devices, and more specifically relates to an energy-absorbing decompression protection frame device installed on the rear frame body of a heavy-duty vehicle. Background technique [0002] With the continuous improvement of living standards and machinery manufacturing levels, various types of vehicles on the road are also increasing. Driven by the increasing number of vehicles, the number of vehicle accidents is also increasing. Bar, the protective bar used in automobiles at present, most of the bumpers use steel railing-like devices. When the car collides with other objects, it only plays the role of head-to-head and force-blocking, although it can reach a certain extent The purpose of protecting the car, but this protective device can not buffer, absorb and consume the impact force well, and the effect of shock absorption and decompression is not good.

AI Technical Summary

Problems solved by technology

[0004] One is that the flexibility and safety protection are low. The main focus of the existing devices is how to cushion, mainly through elastic telescopic rods or springs, to perform a certain degree of cushioning and shock absorption in the event of a vehicle collision accident. It cannot start from a fundamental point of view. For example, in the event of a vehicle collision accident, through structural improvements, the direction of the impact force is changed, and the force is unloaded to minimize the damage caused by the impact; moreover, shock absorption The structure is relatively simple and the effect is poor. When the front of the vehicle is hit, it is not possible to use multiple shock-absorbing structures and multiple shock-absorbing structures to cooperate with each other to reduce the impact of the impact to the greatest extent to improve safety.
