Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of road safety, in particular to an anti-collision buffer vehicle with multi-stage energy absorption. Background Art
[0002] At present, most highway maintenance operations occupy one lane for road construction, and place safety facilities such as warning cones and construction signs. However, due to the large number of vehicles behind and the high speed during maintenance operations, there are still cases where vehicles mistakenly enter the construction area. Once a vehicle breaks into the construction site, it not only seriously threatens the lives of construction workers, but also easily triggers a chain of traffic accidents, causing greater losses of life and property.
[0003] Most of the existing anti-collision cushions adopt a passive impact method, that is, the incoming vehicle directly collides with the anti-collision cushion to absorb energy. Although this method can protect construction workers and equipment from collision damage to a certain extent, its limitations are also obvious. First, the passive impact method cannot predict and actively respond to potential collision risks in advance; second, due to the passive impact method, it is impossible to actively adjust the damping, which hinders the absorption of full energy. In addition, most construction site protection still relies on traditional manual monitoring and manual inspections, which have many limitations. For example, the monitoring range is limited, data collection is not comprehensive, and the response speed is slow. Once an accident occurs, the subsequent rescue and repair measures are often not timely, and it is difficult to effectively avoid or reduce the occurrence of secondary accidents. Summary of the invention
[0004] In view of the above problems, the utility model provides an anti-collision buffer vehicle with multi-stage energy absorption, which improves the energy absorption efficiency of the collision by improving the multi-stage energy absorption buffer structure of the rear fender of the engineering vehicle, thereby improving the safety protection level.
