Dashboard active pop-up self-locking limit energy absorbing device and dashboard

Abstract

The invention discloses a dashboard active pop-up self-locking limit energy absorbing device and a dashboard. The active pop-up self-locking limit energy absorbing device comprising a jacking device,a self-locking limit structure and a tearing energy absorbing structure is characterized in that the top end of the jacking device is fixed on a dashboard; the self-locking limit structure is disposedon the side wall, near the dashboard, of the jacking device; the tearing energy absorbing structure is arranged on the side wall, far from the dashboard, of the jacking device; the end portion, far from the jacking device, of the tearing energy absorbing device is fixed on a vehicle body; when a vehicle has a frontal collision, the jacking device lifts the dashboard forward; when the dashboard moves a predetermined distance, the self-locking limit structure locks the dashboard; when a human leg is in contact with the dashboard, the tearing energy absorbing structure is torn and deformed; theactive pop-up self-locking limit energy absorbing device is arranged on the surface, far from a human body, of the dashboard. The dashboard active pop-up self-locking limit energy absorbing device andthe dashboard have the advantages of being simple in structure and low in cost, being capable of effectively reducing frontal impact on human leg injuries, and enabling motion postures of a human body after collision to be in an optimal state.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an instrument panel active pop-up self-locking limit energy-absorbing device and an instrument panel. Background technique [0002] The main direction of the development of modern automobile technology is safety, environmental protection and energy saving. Among them, what has a direct relationship with people's lives and property is automobile safety. The research on automobile safety is usually divided into two categories: active safety and passive safety. Active safety refers to taking safety measures before a traffic accident occurs. Avoid accidents as much as possible. Passive safety refers to the use of automotive structural design and passive safety devices to reduce the degree of injury to the driver, passengers and pedestrians outside the vehicle as much as possible when an accident occurs. With the increasing number of automobiles and the increase of vehicle spee...

AI Technical Summary

Problems solved by technology

[0003] The damage to human legs caused by frontal collision and the optimization of human body posture after collision have always been difficult problems to solve. At present, the damage to human legs caused by frontal collision is mainly to optimize the shape of the instrument panel, and the optimization of the shape of the instrument panel leads to a complex overall structure. The manufacturing cost is relatively high, and the effect is relatively simple and not obvious. It cannot well reduce the damage to human legs caused by frontal collision. At the same time, there is no effective optimization method for human body movement posture after frontal collision
