Problems solved by technology

However, the device is suitable for a single working condition, and can only be applied to medium and low-speed rear collisions. For high-speed rear collisions, the device cannot provide a large restraint platform force; and for secondary collisions of vehicles, the seat of the device will slide forward. Very likely to cause other injuries to the occupants

Abstract

The invention relates to an intelligent sliding seat capable of preventing a whiplash injury. When a rear-end colliding accident happens, sliding guide rails on the sliding seat slide backwards, traction blocks are made to slide backwards, so that squeezing action is generated to speed limiting blocks by the traction blocks, elastic pieces are then squeezed to absorb energy, and thus stable backward sliding of the seat is achieved to protect the neck of a passenger against the injury. Meanwhile, the sliding seat can adapt to working conditions of various rear-end collision speeds by setting the elastic coefficients of the energy absorption elastic pieces. On the other hand, the sliding seat is further provided with energy absorption steel discs for energy absorption. Large restraint platform force can be provided for the seat when rear-end collision occurs through the energy absorption of the two modes.

Description

technical field [0001] The invention mainly relates to an intelligent sliding seat for preventing whiplash, and belongs to the technical field of automobile active safety. Background technique [0002] Rear-end collision accidents are one of the most common forms of collisions on the road. Although the fatal injuries to occupants caused by them are relatively small, the social expenditures caused by whiplash injuries in the neck 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 the injury is not clear, but it is generally believed that reducing the relative movement of the occupant's trunk and head can reduce whiplash injuries. Based on this knowledge, some automakers have created seats that reduce whiplash and have proven their effectiveness in crash tests. The existing anti-whiplash seats on the market are complex in...
