An externally hung type energy-absorbing seat

Abstract

The invention discloses an externally hung type energy-absorbing seat comprising a backrest frame, a seat, an unlocking mechanism and energy absorbing devices. The seat is mounted on the backrest frame in a mode that the height of the seat is adjustable. The unlocking mechanism is fixedly connected with the seat and is arranged on the backrest frame by sliding sleeves sleeved on the backrest frame. The upper ends of the energy absorbing devices are fixed on the backrest frame, and the lower ends of the energy absorbing devices are fixedly connected to the unlocking mechanism. Each energy absorbing device includes an inner tube, an outer tube, a steel strip and a pin. The outer tube is sleeved outside the inner tube, and the steel strip is provided with an elastic bending structure. The pins are respectively arranged on both sides of the elastic bending structure in an intersecting mode, and the ends of the pins are fixed on the inner tube. The both ends of the steel strip are fixed tothe upper and lower ends of the outer tube. The lower end of the inner tube is connected to the unlocking mechanism, and the upper end of the outer tube is fixedly connected to the backrest frame. According to the invention, with the above structural design, a better cushioning and shock-absorbing effect is achieved; higher comfort and safety degrees are reached; and irreversible damages to humanbodies are reduced.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an external energy-absorbing seat. Background technique [0002] When an armored vehicle or mine-protected vehicle explodes upon touching a landmine and is attacked by the blast wave of the explosive, many casualties are not caused by the breakdown of the armored vehicle, but more by the blast wave. Therefore, the shock absorption and buffering of the seats of the existing armored vehicles or lightning-proof vehicles is an important topic of current research. The existing lightning-proof seats usually use springs as shock-absorbing components. A small range of vibration frequency, the shock absorption effect is not good, and it cannot provide good protection. Contents of the invention [0003] In view of the above shortcomings, the purpose of the present invention is to provide an external hanging energy-absorbing seat, which has the advantages of good cushioning and energy-absorbing...
