Technical Field

Background

When an automobile is in a collision accident, the dissipation and the migration of the kinetic energy of the automobile and passengers play an important role in the safety protection of the collision of the automobile, and the damage degree of the passengers is related to the posture regulation and control of the passengers, the degree of the kinetic energy absorbed by different structures and the working stroke during the dissipation of the kinetic energy. By triggering the seat to slide when in collision, part of kinetic energy of passengers and vehicles can be absorbed by related energy absorption mechanisms in the sliding process, so that the kinetic energy ratio absorbed by the bodies of the passengers is reduced, the kinetic energy ratio absorbed by the vehicle structure is improved, and the riding and landing efficiency is improved.

Among them, the design of the seat using sliding of the car seat to absorb collision energy and reduce whiplash injury in rear-end collision has passed the examination. For example, patent document (CN203496713U) discloses an adaptive intelligent translational energy absorbing seat for use in a rear-end collision, in which the vehicle seat can slide by the inertial force applied to the occupant during the rear-end collision, and the collision kinetic energy is partially transferred to the sliding stroke during the sliding process, and then absorbed by mechanisms such as plastic deformation of an external damper and friction with structures such as a guide rail during the sliding process.
