Description

Car drowning rescue device

technical field

The invention relates to the technical field of vehicle security, in particular to a car drowning lifesaving device.

Background technique

In the face of natural emergencies such as heavy rain, the vehicle will encounter the danger of drowning. In addition, accidental traffic accidents will also cause vehicle drowning, which will threaten the lives of drivers and passengers. How to realize self-rescue and guarantee personnel during the car drowning process , the safety of automobiles and belongings has become a key research topic in the automobile security industry.

Contents of the invention

The invention provides a car drowning life-saving device to solve the problem in the prior art that it is difficult to save the car from drowning.

The technical solution adopted by the present invention to solve its technical problems is:

A drowning rescue device for a car, which consists of three sets of sensors, a microprocessor, an inflator and an airbag. The airbag includes a front airbag, a middle airbag and a rear airbag. The front airbag is installed in the middle of the front bumper of the car, and the middle airbag is installed in the front wheel. The rear airbag is installed under the luggage compartment fender, and the sensor is a pressure sensor. The first set of sensors is set at the front airbag, the second set of sensors is set at the middle airbag, and the second set of sensors is set at the middle airbag. Three groups of sensors are arranged at the rear air bag, and the circuits of the three groups of sensors are connected in series with the microprocessor, and the microprocessor is respectively connected with the front air bag, the middle air bag and the rear air bag through three inflators.

The above-mentioned airbag is provided with a deflation one-way valve, the bottom of the front bumper in front of the front airbag is provided with a front airbag limiting plate, and the bottom of the rear bumper behind the rear airbag is provided with a rear airbag limiting plate.

Above-mentioned air bag adopts waterproof and heat-resistant material to make.

The packaging cover of the above-mentioned airbag is a hinge mechanism, which ensures that the airbag moves to the inside of the bottom of the car so as to hold up the vehicle body after drowning.

The working principle of the device of the present invention: the sensor and the microprocessor are used to judge the degree of drowning, and transmit and send signals; the inflator generates an ignition action according to the signal indication, ignites the solid fuel and generates gas to inflate the airbag, so that the airbag rapidly expands, and the airbag is equipped with The deflation one-way valve can release the gas when the vehicle is out of danger. When the vehicle suddenly drowns, the occurrence time is only about one tenth of a second or less, so the sensor senses the degree of drowning of the car and sends the signal to the control The controller processes the signal. When it is judged that it is necessary to open the airbag, a signal is sent to trigger the inflator. The inflator ignites quickly and generates a large amount of gas to inflate the airbag. The entire process takes about 10 milliseconds to avoid water entering the car. By room. The first group of sensors is responsible for the ignition signal of the airbags under the front bumper. A second set of sensors is responsible for the ignition signal for the airbags under the panel of the car's passenger compartment. The third group of sensors is responsible for the ignition signal of the airbag under the trunk panel of the car. Three sets of sensors are used to determine whether the front, middle, or rear of the vehicle is drowning. This opens the air bag below the drowning site. The circuit of each group of sensors enters the microprocessor (MCU) in series, the microprocessor (MCU) receives the sensor switch signal, and sends the command to the actuator (inflator), and at the same time closes the engine ignition system to prevent the engine from entering the cylinder. water. The actuator is an inflator, controlled by the vehicle ECU. There are three airbags in total, and it is guaranteed that the width of the expanded airbag exceeds the width of the vehicle body and can surround and seal the tire ring, making the tire also a part of the rescue airbag.

The device of the invention realizes the inflating of the safety airbag arranged at the bottom of the vehicle through the sensor through the inflator during the drowning process of the vehicle, thereby lifting the vehicle body in time to place the drowning, effectively ensuring the safety of personnel, vehicles and property, and having a reasonable design, safety and reliability advantage.

Detailed ways

As shown in Figure 1 and Figure 2, a drowning rescue device for a car is composed of three groups of sensors, a microprocessor, an inflator and an airbag. The airbag includes a front airbag 2, a middle airbag 4 and a rear airbag 6. The front airbag 2 is installed on In the middle of the front bumper 9 of the car, the middle airbag 4 is installed at the bottom of the driver's cabin shield between the front wheel 3 and the rear wheel 5, the rear airbag 6 is installed under the luggage compartment shield, and the front bumper 9 in front of the front airbag 2 The front airbag limiting plate 1 is arranged at the bottom, and the rear airbag limiting plate 7 is arranged at the bottom of the rear bumper 8 behind the rear airbag 6. The sensors are pressure sensors. The first set of sensors is set at the front airbag, and the second set of sensors is set in the At the airbag, the third group of sensors is set at the rear airbag. The circuits of the three groups of sensors are connected in series with the microprocessor. Air one-way valve, the airbag is made of waterproof and heat-resistant materials, and the packaging cover of the airbag is a hinged mechanism to ensure that the airbag moves to the inside of the bottom of the car after drowning so as to support the body.

The working principle of the device of the present invention: the sensor and the microprocessor are used to judge the degree of drowning, and transmit and send signals; the inflator generates an ignition action according to the signal indication, ignites the solid fuel and generates gas to inflate the airbag, so that the airbag rapidly expands, and the airbag is equipped with The deflation one-way valve can release the gas when the vehicle is out of danger. When the vehicle suddenly drowns, the occurrence time is only about one tenth of a second or less, so the sensor senses the degree of drowning of the car and sends the signal to the control The controller processes the signal. When it is judged that it is necessary to open the airbag, a signal is sent to trigger the inflator. The inflator ignites quickly and generates a large amount of gas to inflate the airbag. The entire process takes about 10 milliseconds to avoid water entering the car. By room. The first group of sensors is responsible for the ignition signal of the airbags under the front bumper. A second set of sensors is responsible for the ignition signal for the airbags under the panel of the car's passenger compartment. The third group of sensors is responsible for the ignition signal of the airbag under the trunk panel of the car. Three sets of sensors are used to determine whether the front, middle, or rear of the vehicle is drowning. This opens the air bag below the drowning site. The circuit of each group of sensors enters the microprocessor (MCU) in series, the microprocessor (MCU) receives the sensor switch signal, and sends the command to the actuator (inflator), and at the same time closes the engine ignition system to prevent the engine from entering the cylinder. water.
