RU175926U1 - PASSIVE SAFETY DEVICE FOR DRIVERS AND PASSENGERS OF A CAR - Google Patents

Abstract

The utility model (passive safety device for the driver and passengers of the car) is designed for passive protection of the driver and passengers of the car in case of a side impact, and can be installed on all serial models without significant modification. Allows you to save the living space of the driver and passengers by transmitting and dissipating the kinetic energy of the impact on all the power elements of the body. This is achieved by integrating the reinforcing elements of the side doors into the main power structure of the car body using the threaded connection method. A threaded connection is established between the door reinforcing elements and the front, side, rear pillars, as well as the thresholds of the car. The connection is established using a screw actuator. This design allows you to increase the strength of the body without changing the design of the vehicle.

Description

The utility model relates to the field of automotive industry, in particular to the crew safety equipment located in the side doors of cars, and can be used in their manufacture to protect people in the event of a side impact.

According to accident statistics, a side impact is considered one of the most dangerous, since the contact point is a few centimeters from the body of the driver or passengers.

Currently, on production vehicles, door reinforcements (beams) made of high-strength steel, airbags, curtains and seat belts protect against side collisions.

To increase stiffness and give greater resistance during side impact, a reinforcing element is used in the door - a safety beam, as shown in patents RU No. 2236770 dated June 20, 2008, B60J 5/04; RU 2140858 dated November 10, 1999, B60J 5/04, B60R 19/42; RU 2266834 dated December 27, 2005, B60R 21/02, B60J 5/04.

The disadvantage of these designs is that the safety beam absorbs only part of the impact energy and cannot completely redistribute it to the power elements of the body, since it is connected with them only by door hinges and a lock. The hinges and the lock, in turn, cannot transfer all the impact energy from the door reinforcing elements to the main body structure. For this reason, the body begins to crumple, thereby reducing the living space for the driver and passengers.

The task to which the claimed utility model is directed is to increase the safety level of the driver and passengers in a side collision.

The proposed utility model allows to obtain the following technical result.

1. Preservation of the living space of the driver and passengers in a side collision.

2. The increase in the strength of the body, without changing the design and appearance of the vehicle.

3. An increase in the torsional rigidity of the body.

4. Providing additional protection against breaking doors when trying to steal a car.

For clarification of the utility model, images are attached.

In FIG. 1 is an example of a device arrangement in a car.

In FIG. 2 - general view of the device.

The device consists of reinforcing elements made of high strength steel in the car doors of FIG. 1.1. On the reinforcing elements, or inside them, screw actuators of FIG. 1.2 (electric cylinders with roller-screw or ball-screw transmission), which drive the trapezoidal screws of FIG. 1.3 (thread type may vary). The screws are turned out of the door reinforcing elements through ball nuts integrated in the door reinforcing elements of FIG. 1.4 and are wrapped in the trapezoidal nuts of FIG. 1.5 (the type of thread may vary), embedded in the main power structure of the car body.

Thus, door reinforcing elements are integrated into the main power structure of the car body through a threaded connection, which allows redistributing impact energy, thereby reducing the risk of deformation of doors, pillars, sills and saving living space for the driver and passengers.

This design of the utility model provides:

good resistance to shock loads and vibration;

connection reliability;

positioning accuracy;

greater rigidity;

lack of backlash;

durability;

smoothness of movement;

high efficiency.

The device operates as follows. At the moment of the start of movement, after the signals from the sensors on the closing of all doors arrive, screw actuators establish a threaded connection of the door reinforcing elements with the main power structure of the body, front, middle, rear body pillars, and also through the threshold with a transverse body amplifier.

When the car stops, when the door unlock button is pressed, screw actuators are turned on, and the threaded connection unfolds, thereby opening the door.

At the time of setting the car on a burglar alarm, screw actuators turn on and restore the threaded connection, creating an additional obstacle for attackers. When removing the alarm, the threaded connection is deployed.

Claims (1)
