A sliding seat with self-adaptive anti-whiplash after tail impact

Abstract

The invention relates to a sliding chair capable of preventing a whiplash injury through self-adaptation in a rear-end collision and belongs to the technical field of vehicle active safety. According to the sliding chair, horizontally-moving energy-absorption mechanisms are installed at the two sides below the chair and each horizontally-moving energy-absorption mechanism can provide different constraint platform forces through the methods that a cylindroid capable of rotating is arranged and an energy-absorption steel disc is in contact with a semi-arc face, with the long axis of the cylindroid serving as the boundary, of the cylindroid or in contact with a semi-arc face, with the short axis of the cylindroid serving as the boundary, of the cylindroid, so that the requirement that the sliding chair is suitable for different types of rear-end collision conditions is satisfied and the large constraint platform force is provided for the high-speed rear-end collision. According to the sliding chair, the chair is prevented from sliding forwards and protection is achieved in the secondary collision. Meanwhile, the sliding chair is simple in structure, high in mechanical efficiency, remarkable in protection effect and good in application prospect.

Description

technical field [0001] The invention mainly relates to a tail collision self-adaptive anti-whiplash sliding seat, which belongs to the technical field of automobile active safety. Background technique [0002] Rear-end collision accidents are one of the most common types of collisions on the road. Although the fatal injuries to occupants are relatively small, the social costs of whiplash injuries caused by rear-end collision accidents are relatively large. Whiplash injury refers to the injury caused by the whipping movement of the occupant's neck in a rear-end collision. At present, the mechanism of its injury is not clear, but it is generally believed that reducing the relative movement of the occupant's torso and head can reduce whiplash injuries. At the same time, some car manufacturers have produced seats that reduce whiplash injuries based on this understanding. proved to be effective. At present, the existing neck protection seats for rear-end collision occupants in ...

Problems solved by technology

However, this device has a single research condition and can only be applied to low- and medium-speed rear impacts. For high-speed rear impacts, the device cannot provide a large restraint platform force; the protection performance is single, and the seat will slide forward in the secondary collision of the vehicle, which is very easy to cause Other injuries to occupants; complex structure, low mechanical efficiency, and ineffective protection
