Problems solved by technology

[0003] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art, and to design a new type of passenger car column arrangement and an energy-absorbing structure hidden inside the walls on both sides of the passenger car, which can simultaneously absorb energy in frontal collision accidents and rollover accidents The function of cushioning, while moving the cabin floor when the vehicle is deformed, ensures the living space of the car occupants, and solves the problem that the upper structure of the current passenger car will collapse and deform once the load is too large despite the strength, as well as the frontal collision accident. The force on the front part is too concentrated and the deformation is serious

Embodiment

[0025] Such as figure 1 , figure 2 As shown, a new passenger car collision energy-absorbing safety frame structure includes oblique columns 1 which are arranged on both sides of the passenger car obliquely forward to support the roof, and fixedly connected to the oblique column 1 at the middle and lower parts of the oblique column. 1 Deformed and moved passenger cabin floor 2, and several parallelogram energy-absorbing structures composed of beams 3 located on the side walls of the passenger car connected to the inclined columns 1, the diagonals of the parallelogram energy-absorbing structures are connected with absorbing capable tightrope 4, figure 2 a-f in is the connection point between the energy-absorbing steel cable 4 and the parallelogram.

[0026] The inclined columns 1 are inclined 8-12 degrees toward the front of the passenger car from the bottom to the top, and all inclined columns 1 are inclined at the same angle and direction, and are arranged in parallel on t...

Abstract

The invention discloses a novel passenger car collision energy absorption safe frame structure, comprising oblique columns arranged on the two sides of a passenger car in a forward inclined manner tosupport a car roof, a carriage floor fixedly connected with the lower middle parts of the inclined columns and capable of moving along with the deformation of the inclined column, and a plurality of parallelogram energy absorption structures formed by connection of a beam located on the periphery of the passenger car and the inclined columns, wherein energy absorption steel cables are connected and arranged on diagonal lines of the parallelogram energy absorption structures. By adoption of the novel passenger car collision energy absorption safe frame structure provided by the invention, whenthe car experiences a serious overturn accident with the roof down or a direct impact accident, energy generated during the accident can be uniformly transmitted to the energy absorption devices on the two sides of the car body, so as to avoid personal casualty caused by roof collapse since columns at the two sides of the passenger car are broken; meanwhile, the energy during the accident can be dissipated, so as to avoid serious local car body deformation, thereby effectively improving the occupant protection ability of the passenger car in the accident; the novel passenger car collision energy absorption safe frame structure has the advantages of simple structure and easy arrangement.

Description

technical field [0001] The invention relates to a passenger car frame structure, in particular to a novel passenger car collision energy-absorbing safety frame structure. Background technique [0002] Due to the simple design of the frame structure of the passenger car and the large passenger capacity, traffic accidents are extremely harmful, especially when a rollover accident with the roof facing down occurs, the columns supporting the roof on both sides of the passenger car tend to break and collapse. The roof completely invades the living space of the occupants in the vehicle, resulting in serious occupant casualties. Although my country has formulated mandatory safety standards for the structure of passenger cars, such as GB13094-2007 "Safety Requirements for Passenger Car Structures" and GB / T17578-1998 "Regulations on the Strength of the Upper Structure of Passenger Cars", these standards require that the roof of a passenger car can withstand 1.5 times its own Vehicle ...
