AI Technical Summary
Existing highway anti-collision devices cannot effectively deflect vehicles during a collision; they only absorb energy through device deformation, which cannot effectively reduce damage.
An anti-collision device was designed, comprising a column, roller, shaft, mounting plate, spring, and energy-absorbing box. The roller deflects the vehicle, and the shaft transmits force. The mounting plate compresses the spring and piston for cushioning, and the energy-absorbing box absorbs excessive force, thus achieving buffer protection.
It effectively deflects the vehicle and absorbs collision energy through a multi-layered buffer structure, protecting the vehicle and passengers and preventing the vehicle from running off the road.
