Side impact prevention energy absorption plate for automobile door

Abstract

The invention provides a side impact prevention energy absorption plate for an automobile door, and relates to the technical field of automobiles. The side impact prevention energy absorption plate comprises an elastic protective layer, a hexagonal energy absorption grid and an outer layer steel plate which are arranged from inside to outside, wherein the elastic protective layer is internally provided with at least one layer of carbon fiber net; the thickness of the elastic protective layer is 2-5mm, the thickness of the hexagonal energy absorption grid is 10-20mm, and the thickness of the outer layer steel plate is 3-6mm; the inner side of the elastic protective layer is stuck with a soft sponge cushion; the thickness of the soft sponge cushion is 5-8 mm; when side impact occurs, the side impact prevention energy absorption plate can protect the bodies of a driver and passengers, and the pressure of the automobile door sinking inwards is prevented; simulation experiments prove that an automobile which is additionally provided with the side impact prevention energy absorption plate can absorb 46.21% of the collision kinetic energy when the side collision occurs, so that the personal safety of the driver and the passengers is effectively protected.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an anti-side impact energy-absorbing panel for an automobile door. Background technique [0002] As an important tool for the development and progress of modern society, automobile has become an indispensable basic factor for the rapid development of our world. The rapid development of the automobile industry has brought us safety issues that cannot be ignored. Because most of the urban traffic in our country is dominated by level intersections, the probability of side collision accidents is very high. According to the survey, among the collision accidents in China in 2007, frontal collisions accounted for 59%, and side accidents accounted for 27%. Although side accidents are less than frontal collisions, according to investigations and researches, among all types of fatal accidents, the death rate of side collisions is as high as 44%, ranking first. Among all traffic accid...

Problems solved by technology

[0003] The car door and the car body are not an integral structure. When a side collision occurs, the energy generated by the impact on the door cannot be well dispersed and absorbed by the car body. Therefore, when the car door is hit, it often causes great harm. In addition , the driver and passengers are often located inside the door. When the car door is hit and dented, it will often squeeze the body of the driver and passenger, causing injuries to the internal organs or torso of the driver and passenger, and serious personal injury. At present, there are certain solutions, such as As long as all the side doors of the car are made of ultra-high-strength steel with a large thickness, the side structure of the entire car body is strengthened, and the welding process is optimized, which can also protect the driver and passengers in the event of a side collision accident, but the cost of doing so is too high Yes, ordinary economical cars can't bear it at all
