A safety protection device for a vehicle and the vehicle

Abstract

The invention provides a safety protection device for a vehicle and the vehicle, and relates to the technical field of vehicle components. The safety protection device includes: a support rod arranged along the transverse direction of the vehicle, the support rod is arranged on the side of the seat of the vehicle close to the door, and an end surface is provided on the end close to the door of the vehicle; the power mechanism , is connected with the support rod, and the power mechanism is used to push the support rod to move toward the vehicle door when the vehicle collides so that the end surface is in contact with the vehicle door to support the vehicle door. The safety protection device provided by the invention can enhance the protection of occupants when the vehicle is collided with the side.

Description

technical field [0001] The invention relates to the technical field of vehicle parts, in particular to a safety protection device for a vehicle and the vehicle. Background technique [0002] Side collision is a common vehicle collision accident, and this type of collision will cause great damage to the driver and passengers, especially when the vehicle hits a tree or a utility pole from the side, it will cause serious injury or even death to the occupant. The structure of the side door is softer than that of the front cabin, and the deformation and energy absorption space is small. When the vehicle side door hits the rigid column, the deformation and intrusion are large. Serious injuries to the chest, pelvis, etc. [0003] Therefore, in the prior art, side airbags and side air curtains are designed during the research and development of side impact protection of vehicles to protect the occupant's head and chest when severe collisions occur. This type of design can protect ...

AI Technical Summary

Problems solved by technology

This type of design can protect well when the side is hit by an object as wide as a vehicle, but it has little effect when the side hits a rigid column such as a tree or a utility pole, because the rigidity of the side door is relatively small , and the amount of deformation intrusion is faster and larger. At this time, the sensor signal for airbag detonation is late. When the airbag receives the detonation signal and detonates, the space between the seat and the door is already extremely small, which cannot meet the space requirements for airbag deployment. This state Under the circumstances, the airbag will not only fail to protect the occupant, but will increase the degree of injury of the occupant, which has the opposite effect

In order to solve the problem of late airbag ignition, some high-end models install pressure sensors in the side doors, but the pressure sensors have strict requirements on the sealing effect of the doors. At present, the sealing performance of the side doors of most models cannot meet this requirement, and the cost of pressure sensors is relatively high. , so this method cannot be widely used
