Inner roof energy-absorbing structure, vehicle roof and vehicle

Abstract

The invention relates to the technical field of vehicle safety and especially relates to an energy absorption structure of an in-vehicle ceiling. The energy absorption structure comprises a baseplate, reinforcing ribs and crumple parts, wherein the baseplate comprises an adhesion face adhered with a ceiling inner decorative panel as well as an installation face turning the back to the adhesion face; the reinforcing ribs are firmly installed on the installation face and are composed of multiple parallel ribs which are spaced at intervals in the length direction of a vehicle body; and the crumple parts are arranged in the length direction of the vehicle body, are adjacent to the reinforcing ribs and are firmly disposed on the installation face in an upwards raised manner, and the crumple parts are nearer to the front end of the vehicle body than the reinforcing ribs. The energy absorption structure of the in-vehicle ceiling is disposed between a ceiling metal plate and the ceiling inner decorative panel in a fitted manner; the reinforcing ribs and the crumple parts are arranged in the length direction of the vehicle; and the reinforcing ribs are combined with the crumple parts. In this way, collision force borne by a passenger's head can be effectively dispersed and absorbed; safety protection to the passenger can be effectively enhanced when the vehicle suffers from side collision or side overturning; and risks for the passenger to suffer from damage can be reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle safety, in particular to an energy-absorbing structure of a vehicle roof, and at the same time, the invention also relates to a vehicle roof having the energy-absorbing structure of the vehicle roof and a vehicle having the vehicle roof. Background technique [0002] As more and more vehicles enter people's lives, people have higher and higher requirements for vehicle safety. In the prior art, in order to improve the safety of vehicle collisions, vehicle designers have added collision energy-absorbing mechanisms to vehicle bumpers, body panels, etc., or added safety airbag mechanisms in vehicles, so that when a vehicle collision occurs, It can protect the occupants of the car. [0003] As mentioned above, when the vehicle collides or rolls over, the unprotected pillars and ceiling of the vehicle will cause greater damage to the occupants. Therefore, in order to reduce the damage of the interior p...

Problems solved by technology

[0003] As mentioned above, when the vehicle collides or rolls over, the structure such as the pillars and the roof without protective measures will cause greater damage to the occupants. The method of using roof trim materials to improve the protection of occupants, but the effect of this method is not obvious enough; there are also structures such as using filled polyurethane foam materials to improve impact force absorption, or adopting the geometric design of thermoforming cones and metal energy-absorbing brackets To reduce the damage of the collision force to the occupants, due to its unreasonable structural design, the absorption effect of the collision energy is not good
