As the core function of the vehicle, it is equipped with a dedicated anti-collision buffer device based on the principle of energy absorption and conversion. In the event of a rear vehicle losing control and rear end collision, the collision energy can be effectively attenuated and converted through the deformation and buffering of the anti-collision buffer module, greatly weakening the impact force and avoiding the uncontrolled vehicle from directly entering the work area. It comprehensively protects the safety of on-site construction personnel, construction equipment, and road facilities, while also reducing the damage of out of control vehicles and drivers and passengers, achieving a two-way protection effect. It is designed to provide comprehensive passive protection for operators and equipment in temporary lane closures, road construction and other scenarios, and can adapt to the requirements of 100K protection level related operations, in line with road construction safety regulations.
