Definitions
- the invention relates to techniques for protecting the driver and passengers of land vehicles, as well as empty vehicles in extreme situations, such as floods, falls in the event of a vehicle accident in a body of water, lake, river, etc.
- a known car security system which contains a pneumatic pillow located under the bottom of the car in a container.
- a sensor for the presence (level) of water which is electrically connected to the central controller and through it to the pyrotechnic gas generator (1).
- the water presence sensor sends a signal to the controller, which gives a signal for the operation of the pyrotechnic gas generator.
- the produced gas fills the pneumatic cushion located under the bottom of the car and the car stays afloat.
- a manual start button for the gas generator is also provided.
- the disadvantages of the known security system is that only one airbag is provided. It is known that during a flood / hurricane, various objects float in the water, including objects having sharp and cutting edges, which can cause a cut / rupture of the pillow, which will render the security system unusable. In addition, the pyrotechnic gas generator used almost immediately causes gas to be injected into the cushion, which can lead to irreversible deformation of the cushion material and will only allow one-time use (similar to airbags installed in the passenger compartment).
- the problem to which the invention is directed is to create a reliable and safe operation system that prevents flooding of a ground vehicle.
- the security system to prevent flooding of a land vehicle contains airbags evenly distributed in the working position under the vehicle’s bottom, which are placed in the inoperative position in boxes / covers ,; a compressed gas cylinder connected through a reducer to a gas distribution pipe equipped with a main electro-pneumatic valve, to which an electric air pump is connected, while the gas distribution pipe is equipped with a gas pressure sensor in the gas pipe; moreover, on the gas pipes connecting each air bag to the distribution gas pipeline, electro-pneumatic and check valves are installed, and each pillow is equipped with a gas pressure sensor that has filled it; the system also contains water sensors, one of which is located under the hood in the area of the vehicle engine and at least two water sensors are located in the passenger compartment means, while the sensors of the presence of water are electrically connected to the main electro-pneumatic valve of the distribution gas pipeline, and the pressure sensors in the pillows are electrically connected to the electro-pneumatic valves of the pillows, and the gas pressure sensor in the distribution gas pipeline is electrically connected to
- the presence of a number of pneumatic airbags will allow maintaining the safety system even if one or several airbags are damaged.
- the presence of at least three water sensors electrically connected to the main electro-pneumatic valve will ensure reliable automatic operation of the system and filling the airbags with gas, excluding the possibility of "idle" operation of the system from only one water presence sensor installed under the hood of the vehicle, for example, when yes accidentally hit the sensor due to rain and / or the presence of puddles in the path of the vehicle.
- the presence of electropneumatic and non-return valves on gas pipelines connecting the distribution gas pipeline to each pillow, as well as supplying each pillow with a gas pressure sensor allows for unidirectional gas flow only inside the pillows.
- Figure 1 is a plan view on the bottom of the car from the outside;
- Figure 2 is a pneumatic diagram of a security system;
- Fig.Z is an electrical diagram of a security system;
- Figure 4 arrangement of sensors for the presence of water.
- the security system contains eight airbags Pi, ⁇ 2, ⁇ , ... PE, which are evenly distributed outside the bottom of the vehicle 1 and in the idle position are placed in boxes / covers Ci, C2, ⁇ , ... ⁇ réelle, which can be installed either from the outside of the bottom 1, or in another part of the vehicle body, which involves the operation of the security system.
- a cylinder 2 with compressed gas is installed, which through a reducer 3 and the main electro-pneumatic valve Vo is connected to a gas distribution pipe 4 provided with a gas pressure sensor Ri.
- An electric pneumatic pump M is also connected to the electro-pneumatic valve Vo.
- Ps the electro-pneumatic valves Vi, V2, V3 ... Vs and non-return valves Si, are installed S2, S3 ... Ss.
- Check valves can also be located directly in the pneumatic cushions.
- Each pillow is equipped with a pressure sensor of the gas Ri, R2, R3 ... R8 located in it, which are electrically connected to the electro-pneumatic valves Vi, V2, Vs ... Vs.
- a water presence sensor 6 is installed under the hood of the car in the engine area.
- Paired sensors 7, 8, 9, 10 ... 14 for the presence of water are installed inside the vehicle interior in the areas of the front and rear seats, which are electrically connected to the water presence sensor 6 and to the main electro-pneumatic valve Vo.
- a button 15 is installed in the cabin, electrically connected to the main electro-pneumatic valve Vo.
- the positions QFi, QF2, QF3 indicate the automatic machines that provide electrical communication between the sensors and the executive bodies of the security system.
- the security system operates as follows. In extreme situations - flooding, a car crash in an accident in a body of water, etc., sensors 6 - 14 of the presence of water under the engine and in the passenger compartment are triggered. To open the main electro-pneumatic valve Vo, it is enough to activate at least two sensors in the passenger compartment and a sensor 6 installed in the engine area. Through the gearbox 3 and the main electro-pneumatic valve Vo, gas from the cylinder 2 through the distribution gas line 4 enters the pneumatic bags Pi, P2, Pz, ... Ps, passing through the electro-pneumatic valves Vi, V2, V3 ... Vs and check valves Si , S2, S3 ... Ss.
- the electro-pneumatic valves Vi, V2, V3 ... Vs are closed. Thanks to the inflated pillows, the car is afloat. In the event of damage, for example, a puncture of one or several pillows, gas is released (leak) from them, the corresponding pressure sensors Ri, R., R3 ... ra3a in the pillows are activated and the corresponding electro-pneumatic valves Vi, V2, V3 ... open.
- the pressure in the distribution gas line 4 drops and the pressure sensor Ri is triggered, giving a signal to turn on the electric drive of the air pump M, which will supply gas (air) to the damaged pads Pi, P2, Pz, ...
- the signal sensor Ri will turn off the air pump M and vice versa, when the pressure drops, the air pump M will turn on.
- the above example of a specific implementation of the invention in no way limits the scope of rights set forth in the claims.
- the invention can be used, for example, for micro - buses, as well as for other land vehicles.
- the determination of the number of pillows, their placement and size / volume can be determined directly depending on the size and weight of the vehicle. Due to the fact that the dimensions / weight of ground vehicles of various types / categories are within comparable limits, then the supply of these vehicles with a protection system can be carried out from a unified series / set of systems made in accordance with the claimed invention and adapted to a specific transport means.
