Description

The utility model relates to vehicle safety, and in particular to warning devices against a car collision, for example with another car, and preventing the death of a driver and passengers.

A number of inventions are known that relate to this topic, for example, JPH07156749 A, 06/20/1995. RU 2261187 C2, 09/27/2005. DE 102005048627 A1, 05.16.2007, FR 2927034 A1, 08/07/2009, US 2010269730 A1, 10.28.2010, DE 10014832 A1, 04.10.2001.

One of the closest technical solutions is the pedestrian and car driver protection device, which has an external airbag in the vehicle structure, which has a bucket-shaped shape, can close the windshield and is folded in the body compartment immediately in front of the windshield. With the concave side of the bucket, the airbag is facing pedestrians, and the airbag can consist of one continuous section or of several sections, inflated alternately, as a result of which partitions are installed inside its walls with openings between the sections, and ensuring the adoption of a bucket-shaped airbag (patent for the invention of the Russian Federation 2547120 published on 04/10/2010).

The disadvantage of this design is that this design does not provide sufficient security, for example, if a person lands his head in the bucket-shaped part, then fractures of the cervical spine and other injuries are possible.

As a prototype, the applicant selected a vehicle collision avoidance device containing means for ensuring the safety of the driver and passengers, means for protecting the car, a control system and auxiliary devices, characterized in that the means for protecting the car are made in the form of two-level airbags located in front and rear bumpers along their entire length, as well as single-level pillows located along the width of the front and rear doors of the car I, the monitoring system further comprises a traffic safety area sensors on the front and rear bumpers and the front and rear doors (utility model patent of the Russian Federation №75357, publ. 10.08.2008.).

The disadvantage of this design is its low efficiency.

The technical task of this utility model is to reduce the likelihood of death of the driver and passengers in the car.

The technical result is a change in the trajectory of the approaching vehicle in a collision.

The technical problem is achieved in that the vehicle collision avoidance device includes a control unit for airbags, airbags that can be deployed outward, characterized in that the airbags in the open position are made sectional and form a conical surface around the car.

Comparison of the claimed utility model with the prototype shows that it differs in the following features:

airbags in the open position are made sectional;

airbags in the open position form a conical surface around the car.

Therefore, we can assume that the claimed utility model meets the criterion of "novelty."

A utility model can be manufactured using well-known technical means, therefore it meets the criterion of "industrial applicability".

In FIG. 1 shows the inventive device in its initial position - a top view, in FIG. 2 shows the inventive device in an open form - a top view, in FIG. 3 shows the inventive device in the initial position - side view, in FIG. 4 shows a sectional view of the position of the airbags — a rear view; FIG. 5 shows a cross-sectional view of the structure of the outer cushion.

The figures show the following items:

1 - car body;

2 - a computer control unit that analyzes information from the detection unit and sends out a signal for airbag deployment from the side from which there is a threat of collision;

3, 4, 5, 6 - blocks detecting the danger of a collision with a car (Fig. 1, 3);

7, 8, 9, 10 - external, inclined, multi-chamber, inflatable airbags: when folded, installed in the outer side of the car (Fig. 1,3); in the open position, each pillow that completely covers 1/4 of the diameter of the car and forms an inclined surface facing the approaching car (Fig. 2);

11 - pillow chamber;

12 - flexible elements that partially cover the surface of the pillow reduce the coefficient of friction (similar to pile).

The device operates as follows

If a collision risk is detected, the vehicle detection unit 3, 4, 5, or 6 transmits a signal to the computer control unit 2. Computer control unit 2 sends a control signal to the external airbag (7, 8, 9, 10), which is triggered from the other side where there is a threat of collision.

Then her or their triggering occurs. For example, an external airbag 7, interacting with an approaching car, opens and forms an inclined surface covered in the lower part and in the front with hollow elements 6 that facilitate the movement of the car at an angle along the pillow upwards, while the car wheels rest on the inclined surface of the external airbag 7 The approaching car changes direction, slows down and stops. At the same time, in order to ensure the hardness of the airbag 7 and increase its load-bearing capacity, the vertical airbag 11 is provided in the airbag design. They allow you to evenly distribute the vehicle weight through the contact spot simultaneously to several chambers under pressure, which allows to increase the hardness and strength of the inclined surface of an external airbag.

Thus, the claimed utility model reduces the likelihood of death of the driver and passengers in the car.
