RU216542U1 - DEVICE TO PREVENT VEHICLE ROLL-OVER - Google Patents

Abstract

The purpose of the utility model is to increase reliability and simplify the design. The device for preventing rollover of the vehicle has a roll sensor 1, which is included in the electrical circuit of the vehicle and contains a dielectric housing, in the upper part of which contacts 2 are fixed along the perimeter, and in the lower part along the perimeter, series-connected contacts 3 are fixed. partially filled with a conductive liquid 4, in a horizontal position, closing the series-connected contacts 3, turning them into normally closed ones. The design has increased reliability, since the tilt sensor included in the device to prevent the vehicle from rolling over does not have mechanical links.

Description

The utility model relates to mechanical engineering, in particular to devices that reduce the likelihood of a vehicle tipping over, and in particular to devices that increase the safety of using vehicles.

A device for preventing rollover of a vehicle is known, comprising a roll sensor connected to the vehicle with the possibility of transverse angular deviation from the vertical axis for closing one and opening other contacts included in an electrical circuit powered by a generator, in series with sound and light alarms, while The roll sensor is a pendulum rod with a load at the end, pivotally fixed in the center of gravity of the vehicle with an additional possibility of longitudinal angular deviation for contact with contacts located around the pendulum rod (RF Patent 2115581, 1998).

The disadvantages of this device are limited functionality; design complexity; operation of the device only at four points (0-360°), 90°, 180°, 270° and the presence of "dead space" from 0° to 90°, from 90° to 180°, from 180° to 270°, from 270 ° up to 360°, where operation is impossible; the patent requires installation of the device at the center of gravity of the vehicle, which causes additional difficulties in determining this center and the likely impossibility of installing the device at the center of gravity of the vehicle.

The closest analogue to the claimed utility model is a device for preventing a rollover of a vehicle, containing a roll sensor rigidly fixed to the vehicle and made in the form of a pendulum rod with a load at the end with the possibility of angular deviation in the vertical plane to affect the contact blocks located around the pendulum rod and included in the electrical circuit powered by the generator, in series with sound and light alarms, and the contacts of each block interact with the load of the pendulum rod through a bracket fixed in the upper part of the dielectric plate and connected to the corresponding segment of the ring, while normally closed contacts are connected in series the contacts are electrically connected through an electromagnetic switch to the internal combustion engine ignition system (RF Patent 2205112, 2006).

The disadvantages of this device are the complexity of the design and the lack of reliability of the mechanical part of the sensor.

The purpose of the utility model is to increase reliability and simplify the design.

The task is achieved by the fact that in the device for preventing rollover of the vehicle, containing a tilt sensor mounted with the possibility of rigid fixing on the vehicle, and contact blocks included in the electrical circuit, which can be connected to the vehicle generator, in series with sound and light alarms , and the contacts connected in series are installed with the possibility of electrical connection through an electromagnetic switch with the internal combustion engine ignition system, the tilt sensor is made in the form of a dielectric cylinder, the internal cavity of which contains a conductive viscous liquid, the contacts of each block are fixed around the perimeter in the upper and lower parts of the internal cavity of the tilt sensor, in this case, the series-connected contacts are placed in the lower part of the tilt sensor, and the contacts of the upper part of the tilt sensor are electrically connected to the coil of the electromagnetic switch, light and sound alarms.

In FIG. 1 shows a vehicle roll prevention device associated with a generator and an internal combustion engine when the vehicle is in a horizontal position.

In FIG. 2 shows a device for preventing a vehicle from rolling over, associated with a generator and an internal combustion engine, when the vehicle is tilted to the limit angle of inclination.

The device for preventing rollover of the vehicle contains a roll sensor 1, made in the form of a dielectric cylinder, in the upper part of which contacts 2 are fixed along the perimeter, and in the lower part along the perimeter, series-connected contacts 3 are fixed. The cavity of the roll sensor 1 is partially filled with a conductive liquid 4, with in a horizontal position closing series-connected contacts 3. Roll sensor 1 is rigidly attached to the vehicle. The vehicle rollover prevention device uses sound 5 and light 6 alarms. In the electrical circuit that feeds this device and the internal combustion engine 7 through the ignition key 8 from the generator 9 of the vehicle, an electromagnetic switch 10 is installed, consisting of an electromagnetic coil 11 and a plate 12.

The device works as follows.

When the vehicle is in a horizontal position, the conductive liquid 4 covers the series-connected contacts 3, and the contacts 2 in the upper part remain open, since the liquid 4 does not reach them. When electric current is supplied through the ignition key 8 from the generator 9, it passes through the series-connected contacts 3 and the electromagnetic switch 10 to the internal combustion engine 7. Sound 5 and light 6 alarms do not work.

When the vehicle tilts to the limit or during sudden braking or impact, the position of the vehicle body and the roll sensor 1 change, and the conductive liquid 4, trying to maintain a horizontal level, closes the contacts 2, electrically connecting them with the series-connected contacts 3. Thus, the electric current through the ignition key 8 from the generator 9, it enters the sound 5 and light 6 alarms and the supply of electric current to the internal combustion engine 7 stops, as the electromagnetic switch 10 is triggered: the electromagnetic coil 11 attracts the plate 12, excluding the restart of the internal combustion engine 7. To resume operation of the internal combustion engine 7, it is necessary to manually turn on the electromagnetic switch 10.

The advantage of the proposed utility model lies in its compactness, significant simplicity of design, compared with the prototype, since the mechanical parts of the sensor are completely excluded and, consequently, the reliability of the design is increased.
