The present invention is described in detail below in conjunction with accompanying drawing:

Referring to Fig. 1, an air compressor system of the present invention, by setting a high-power air compressor on the vehicle, realizes the application of high-pressure gas under multi-scenario or multi-functional conditions; realizes the maximum utilization of the function of the air compressor; satisfies The high-pressure gas production is concentrated, but the application is dispersed; the energy consumption is concentrated and the energy is controllable; the function is controllable through the opening and closing of the gas circuit.

An air compressor system provides high-pressure gas output by setting a high-power air compressor and a cooling system, and then provides gas input for other functional systems through a gas distribution valve to realize the application of an air compressor system, such as air spring charging , gas storage tank inflation, tire inflation, seat back pneumatic support, redundant braking, plateau oxygen absorption, collision protection airbags, high-pressure cleaning headlights and cameras and other functions, to provide customers with a comfortable, convenient and safe car experience.

At the same time, because the high-power compressor is used, the compressor generates a lot of heat and the temperature of the compressed air is also high, so a cooling fan is added to the compressor cylinder to reduce the operating temperature of the compressor; a radiator is installed behind the compressor exhaust port, Reduce compressed air temperature.

Set a high-power motor (above 1kW) to achieve a large flow output and meet the gas volume requirements required for various functional applications.

To ensure the continuity of the motor's work, to realize the demand for long-term air supply, such as inflating tires, the compressor needs to work continuously for a long time (more than 20min). A sufficient cooling system needs to be designed. In the present invention, the compressor is equipped with a fan, and the compressor body is cooled by air cooling, so as to prevent the compressor from overheating during long-term work and affect the system inflation efficiency. The compressed air is dissipated through the cooling fins to reduce The gas temperature during gas supply prevents the overheating protection of the distribution valve and affects the working efficiency.

Air parts include wheels 6, air springs 7, air storage tanks 8, seat back support airbags 14, headlight and camera washers 15, oxygen inhalers 16, seat collision protection airbags 17, and air brake redundant units 18

Taking the air spring inflation function as an example, the process of function realization is described in detail as follows:

Compressed air: The compressor sucks in air from the atmosphere and compresses it in two stages to form high-pressure and high-temperature gas.

Cooling: High-pressure and high-temperature gas enters the heat sink to cool down.

Distribution: High-pressure gas enters the gas distribution valve, and the solenoid valve for air spring inflation is opened according to the control strategy of the air spring or the function definition selected by the user to form a gas passage.

Functional application: The gas from the gas distribution valve inflates the air spring. When the body height meets the requirements, the height sensor signal submits a request to stop inflation, the compressor stops working, the gas distribution valve closes the solenoid valve, and the air circuit is cut off.

Taking the tire inflation function as an example, the process of function realization is described in detail as follows:

Compressed air: The compressor sucks in air from the atmosphere and compresses it in two stages to form high-pressure and high-temperature gas.

Distribution: According to the function definition selected by the user, the solenoid valve for tire inflation is opened to form a gas passage.

Functional application: When the tire pressure requirements are met, the tire pressure sensor signal submits a request to stop inflation, the compressor stops working, the solenoid valve is closed, and the air circuit is cut off.

The present invention realizes the conceptual design that one compressor meets the functional use requirements of multiple systems;

What the compressor achieves is to suck in the atmosphere and output high-pressure gas. Therefore, the input end of the compressor is connected to the atmosphere through the intake and exhaust pipelines (generally non-metallic pipelines, rubber pipes and plastic pipes, including air filters and mufflers), and the output end is connected to the gas distribution valve. The opening and closing of different valves of the distribution valve realizes the gas demand of different systems. The high-pressure gas temperature is very high (above 200°C). To prevent damage to the gas distribution valve, a radiator is added between the two. If the system is not sensitive to gas temperature, For example, the wheels are filled with air, which does not need to go through the radiator. Based on the above, the connection between the components is through the gas circuit connection, and the gas circuit is controlled by the opening and closing of the valve to realize the gas demand of the corresponding system.

The present invention adopts the concept design of air cooling of high-power compressor and radiator cooling of high-temperature gas;

Compressor air cooling is a structural improvement compared to the current compressors used in real vehicles. The current compressor products do not have air cooling, because the current compressor power is small (within 500W), and the temperature of the compressed air is 200 ° C. For a compressor with a power of 1000W, the temperature of the compressed air must exceed 200°C, so increase the air cooling and lower the working temperature to protect the compressor and even the entire system from heat damage.

The radiator is connected to the compressor through the gas path, the gas path here is a metal gas path to increase the heat transfer rate, and the radiator adopts a fin structure to increase the effective heat dissipation area and quickly dissipate the heat of the high-pressure gas to the atmosphere.

The present invention adopts the conceptual design of the distribution mode when the gas is applied;

The distribution method is determined according to the gas demand of the system, and the influencing factors involved are high-pressure gas temperature and gas pressure.

Those that do not require temperature, such as tire inflation, can be directly used to inflate wheels without passing through the radiator; those that are sensitive to temperature, such as air spring inflation, are cooled by the radiator and then inflated. Generally, low-temperature gas is required for system applications.

Regarding the gas pressure, when the output gas pressure of the compressor is higher than the air pressure range required by the system, add a pressure reducer to reduce the air pressure and then apply it to the system. When the output gas pressure of the compressor is lower than the air pressure range required by the system, a booster is added to increase the air pressure and then apply it to the system.

The invention relates to an air compressor system and its application, comprising an air compressor, a gas distribution valve, and gas parts; the air compressor, the gas distribution valve, and gas parts are connected in sequence; Used for high-pressure inflation of air parts; air parts include wheels, air springs, air tanks, seat back support airbags, headlight and camera washers, oxygen inhalers, seat collision protection airbags, air brakes redundant unit;
