Telescopic energy dissipation vehicle impact buffer structure and buffer device

Abstract

The invention belongs to the technical field of traffic safety facilities, and particularly relates to a telescopic energy dissipation vehicle impact buffering structure and device. The vehicle buffering structure comprises a telescopic frame, an energy consumption block and a movable stand column. The telescopic frame comprises four V-shaped plates, each V-shaped plate comprises a first section and a second section, and an energy consumption block is arranged on the second section on one side of a small angle formed by the first section and the second section; the end parts of the second sections of the four V-shaped plates are hinged together, and the energy consumption blocks on the four V-shaped plates are adjacent in pairs; a plurality of telescopic frames are arranged, and the first sections of the telescopic frames are hinged to the movable stand column; the bottom of the movable stand column on one side is connected with a sliding wheel which is arranged in the guide rail. The bottom of the movable stand column on the other side is connected with a universal wheel. Through the design of the structure and the connecting mode of the telescopic frame and the matched arrangement of the energy dissipation blocks, when the vehicle is collided, the collision force is absorbed through core energy dissipation compression and movement of the telescopic frame.

Description

technical field [0001] The invention belongs to the technical field of traffic safety facilities, and in particular relates to an impact buffer structure and a buffer device of a telescopic energy-consuming vehicle. Background technique [0002] Traffic safety is an important part of building a strong traffic country, so the research and development and application of traffic safety facilities have attracted much attention in recent years. In areas with poor traffic conditions, long steep slopes, and poor driving visibility, such as mine roads, mine tunnels, and tunnel interiors, accidents are likely to be caused after vehicles stall or lose control, and accident damage and consequences are very serious. The number of vehicles is getting worse. [0003] In order to avoid accidents, the following protection methods are mainly adopted in the prior art: [0004] (1) The mine road or mine roadway is only protected by simple anti-collision sand buckets or anti-collision pads, a...
