Abstract
Description
[0001] The utility model relates to mechanical engineering, in particular to devices that reduce the likelihood of vehicle rollover, namely to devices that improve the safety of using vehicles.
[0002] A device is known for preventing a vehicle from overturning, comprising 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 deflection in a vertical plane for acting on contact blocks located around the pendulum rod and included in an electrical circuit powered by a generator, in series with an audible and visual alarm, wherein the contacts of each block interact with the load of the pendulum rod through a bracket fixed in the upper part of a dielectric plate and connected to the corresponding segment of the ring, wherein the normally closed contacts connected in series are electrically connected through an electromagnetic switch to the ignition system of the internal combustion engine (Patent of the Russian Federation 2205112, 2006).
[0003] The disadvantages of this device are the complexity of the design and insufficient reliability of the mechanical part of the sensor.
[0004] The closest analogue to the claimed utility model is a device for preventing rollover of a vehicle, containing a roll sensor installed with the possibility of being rigidly fixed on the vehicle, and contact blocks included in an electrical circuit having the possibility of being connected to the generator of the vehicle, in series with sound and light alarms, and the series-connected contacts are installed with the possibility of electrical connection through an electromagnetic switch with the ignition system of the internal combustion engine, characterized in that the roll 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 along the perimeter in the upper and lower parts of the internal cavity of the roll sensor, while the series-connected contacts are located in the lower part of the roll 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 (Patent of the Russian Federation 216542, 2023).
[0005] The objective of the utility model is to improve road safety by improving the information content of the design.
[0006] The stated task is achieved in that in a device for preventing a vehicle from overturning, comprising a roll sensor installed with the possibility of being rigidly attached to the vehicle, and contact blocks included in an electrical circuit having the possibility of being connected to the vehicle generator, in series with sound and light alarms, the roll 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 along the perimeter in the upper and lower parts of the internal cavity of the roll sensor, and series-connected contacts located in the lower part of the roll sensor are installed with the possibility of electrical connection through an electromagnetic switch with the ignition system of the internal combustion engine, the contacts of the upper part of the roll sensor are made of different lengths and are connected to the inputs of the electronic control unit, one output of which is connected to the input of the display unit,and the second output is connected to the coil of the electromagnetic switch, as well as to the light and sound alarms.
[0007] Fig. 1 shows a device for preventing a vehicle from overturning, connected to a generator and an internal combustion engine, when the vehicle is in a horizontal position.
[0008] Fig. 2 shows a device for preventing a vehicle from overturning, connected with a generator and an internal combustion engine, when the vehicle is tilted to the maximum tilt angle.
[0009] The vehicle rollover prevention device comprises a roll sensor 1, implemented in the form of a dielectric cylinder, in the upper part of which contacts of different lengths 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, which, when in a horizontal position, covers the series-connected contacts 3. The roll sensor 1 is rigidly attached to the vehicle. The vehicle rollover prevention device uses an audible 5 and a visual 6 alarm. An electromagnetic switch 10, consisting of an electromagnetic coil 11 and a plate 12, is installed in the electrical circuit that supplies power to this device and the internal combustion engine 7 through the ignition key 8 from the generator 9 of the vehicle.Contacts of different lengths 2 do not have an electrical connection with each other, but are electrically connected to the inputs of the electronic control unit 13, one output of which is electrically connected to the input of the indicator unit 14, and the second output is electrically connected to the coil 11 of the electromagnetic switch 10, light 6 and sound 5 alarms.
[0010] The device operates as follows.
[0011] When the vehicle is in a horizontal position, conductive fluid 4 covers the series-connected contacts 3, while the contacts 2 at the top remain open because fluid 4 does not reach them. When electric current is supplied through the ignition switch 8 from the generator 9, it passes through the series-connected contacts 3 and the electromagnetic switch 10 to the internal combustion engine 7. The sound 5 and light 6 alarms do not function.
[0012] When the vehicle tilts, or during sudden braking or an impact, the position of the vehicle body and tilt sensor 1 change, and conductive fluid 4, in an effort to maintain horizontal alignment, closes one or more contacts 2, electrically connecting them to series-connected contacts 3. In this case, current from contacts 2 is supplied to the inputs of electronic control unit 13. Since contacts 2 have different lengths, electronic control unit 13, having processed the signals from them, sends a signal proportional to the vehicle tilt angle to display unit 14. Therefore, the driver, for example, when driving on slopes, is able to independently prevent the vehicle from rolling over. When the critical tilt angle is exceeded, electronic control unit 13 sends an electrical signal to electromagnetic coil 11.Thus, the electric current through the ignition key 8 from the generator 9 is supplied to the sound 5 and light 6 alarm and the supply of electric current to the internal combustion engine 7 is stopped, since the electromagnetic switch 10 is triggered: the electromagnetic coil 11 attracts the plate 12, preventing the restart of the internal combustion engine 7. To resume the operation of the internal combustion engine 7, it is necessary to manually turn on the electromagnetic switch 10.
[0013] The advantage of the proposed utility model is that it is more informative than the prototype, since the driver sees information about the vehicle's tilt angle and has the ability to independently prevent the vehicle from overturning, which improves road safety.
