RU2405690C1 - Shaped steen safety section channel of automotive door - Google Patents

Abstract

FIELD: transport.

SUBSTANCE: invention relates to machine building, namely to automotive safety systems. Proposed section channel comprises console panels that make a continuation of said panel with cross section shape changed. Console panel feature round shape with eccentric holes. Said holes serve to secure each console panel in car body. Section channel has flat end faces and curved zones located parallel with the latter. Radius of curvature of convergence of curved zones makes at least 100 mm. First console panel 3 features profile with its strain sign opposite that of first console panel 4 to provide for equilibrium sign-variable strains at dynamic load that causes damping or shock absorption of load acting on car body.

EFFECT: higher safety in accidents.

Description

The invention relates to means for protecting car doors from lateral and random angular dynamic impacts that occur during high-speed modes of a moving car in the event of an emergency collision on the road.

Known analogue of RU 2141414 C1, (Joint-stock company "AUTOBAZ") 11/20/1999.

The disadvantages of the analogue include the obscurity of the mentioned protection, associated with the protection of the body of the bus and the inability to use the invention for cars.

The new proposed design of a shaped steel profile for car door safety has passed serial tests at the AvtoVAZ test site and has shown results that are different from the analog and overlap the analog indicators.

The task is achieved in that the shaped steel security profile of the car door, containing consoles (3 and 4), which are a continuous continuation of the profile shape changed in shape, and which are made with round (2) and eccentric (5) holes that secure each console ( 3 and 4) in the car door, made with flat ends (6 and 7) and bending zones (8-11) parallel to them, and the radius of curvature of the mates (12-17) of the bending zones (8-11) is not less than 100 mm, while the console (3) has a profile opposite stress-sign cantilever profile (4), to ensure in the bending zones (8-11) adjacent to the consoles (3 and 4), equilibrium stress zones varying in the signs of stress at the time of dynamic loading, leading to damping and / or vibration absorption of the shock load acting on the car body.

Graphic materials: figure 1 is a plan view; figure 2 is a side projection; figure 3 is a cross section of the profile bb; figure 4 is a cross section of the profile BB; 5 is a view And on the end surface.

Digital designations: shaped steel profile of a car door safety (1); consoles (3 and 4); holes (2 and 5); flat ends (6 and 7); bending zones (8-11); radii of curvature of conjugations (12-15) and (16, 17); positional bending profiles (18-24, 25 and 34); zones of smooth bends (14-17); sections of sections (32-40).

Description of the device.

- Shaped steel security profile of the car door, containing consoles (3 and 4), which are a continuous continuation of the changed section shape of the profile, and which are made with round (2) and eccentric (5) holes that secure each console (3 and 4) in car doors made with flat ends (6 and 7) and bending zones (8-11) parallel to them, and the radii of curvature of the mates (12-17) of the bending zones (8-11) are at least 100 mm;

- the cantilever (3) has a profile that is opposite in sign of stresses to the cantilever profile (4), to ensure in the bending zones (8-11) adjacent to the consoles (3 and 4), equilibrium stress zones varying in the signs of stresses at the moment of obtaining the dynamic loads leading to damping and / or vibration absorption of the shock load acting on the car body.

An example implementation of the device.

1. Shaped steel profile of the car door security is performed with consoles (3 and 4), which are a continuous continuation of the profile shaped in cross-section, and which are made with round (2) and eccentric (5) holes that secure each console (3 and 4) in the car door, made with flat ends (6 and 7) and bending zones (8-11) parallel to them, and the radius of curvature of the mates (12-17) of the bending zones (8-11) is not less than 100 mm.

2. The cantilever (3) has a profile that is opposite in sign of stresses to the cantilever profile (4), to ensure in the bending zones (8-11) adjacent to the consoles (3 and 4), equilibrium stress zones varying in the signs of stress at the time of receipt dynamic loads, leading to damping and / or vibration absorption of the shock load acting on the car body.

Practical manufacturing of a profile from carbon steel 35 and other alloyed carbon steels allows using the boundaries of shock loading of the material in the working zone of their perception.

The industrial applicability of the new technical solution is to use a device to protect human life in a collision of cars in road conditions.

The economic feasibility of applying a technical solution is to use well-known material and is aimed at preserving not only the lives of people, but also road transport.

Claims (1)

Shaped steel security profile of the car door, containing consoles (3 and 4), which are a continuous continuation of the profile shaped in cross-section, and which are made with round (2) and eccentric (5) holes that secure each console (3 and 4) in the door a vehicle made with flat ends (6 and 7) and bending zones (8-11) parallel to them, with the radius of curvature of the mating (12-17) of the bending zones (8-11) being at least 100 mm, with one console (3) has a profile opposite in sign of stress to profile d another cantilever (4), in order to ensure in the bending zones (8-11) adjacent to the cantilevers (3 and 4), equilibrium stresses that vary in signs at the time of dynamic loading, leading to damping and / or vibration absorption of the impact load car body.
