[0004] In related technologies, oxygen supply systems are typically installed in vehicles to alleviate altitude sickness for occupants. While increasing oxygen concentration through these systems can mitigate altitude sickness caused by insufficient oxygen supply to some extent, it cannot address the effects of decreased air pressure.

[0044] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0045] Firstly, please refer to Figure 1This application provides an air supply system 100, including a pressurization unit 1, a cabin pressurization unit 2, an oxygen production unit 3, and a nitrogen receiving unit 8. The pressurization unit 1 provides high-pressure gas. The cabin pressurization unit 2, connected to the pressurization unit 1, receives the high-pressure gas and is adapted to increase the air pressure inside the vehicle cabin. The oxygen production unit 3, connected to the pressurization unit 1, receives the high-pressure gas and produces oxygen. The oxygen receiving unit 4, connected to the oxygen production unit 3, is used at least to oxygenate the vehicle cabin. When the vehicle is traveling in a high-altitude area, the high-pressure gas provided by the pressurization unit 1 can be used to produce oxygen through the oxygen production unit 3, and then oxygenated through the oxygen receiving unit 4 to reduce altitude sickness caused by low oxygen concentration. Furthermore, the high-pressure gas provided by the pressurization unit 1 can also increase the air pressure inside the vehicle cabin through the cabin pressurization unit 2, reducing altitude sickness caused by depressurization. In other words, the air supply unit provided in this application can reduce the impact of altitude sickness on occupants by at least increasing oxygen concentration and cabin air pressure, thus improving the effect of alleviating altitude sickness.

[0046] The cabin pressurization unit 2 can be directly connected to the air conditioning unit through the pressurization unit 1, allowing the high-pressure gas generated by the pressurization unit 1 to be directly delivered to the vehicle's cabin through the air conditioning unit, thereby increasing the cabin air pressure. It should be noted that, in order to create a pressure difference between the cabin and the external environment and maintain a higher air pressure, the windows and sunroof need to be kept closed while delivering high-pressure gas to the cabin to maintain the increased air pressure.

[0047] In some embodiments, please refer to Figure 1 The pressurization unit 1 includes at least one of a compressor 11, an engine turbocharger 12, and an air suspension pump 13.

[0048] The compressor 11 can be an air compressor 11 or an air conditioning compressor 11. The air compressor 11 provides compressed gas and uses the compressed air as power for applications such as the braking system. The air conditioning compressor 11 can compress refrigerant, working in conjunction with other components in the vehicle to achieve cooling or heating effects. The engine turbocharger 12, i.e., the engine turbocharger mechanism, can increase engine power and optimize engine emissions by increasing intake air density. The air suspension air pump 13 can compress gas and then inflate the air suspension to adjust the height and stiffness of the air suspension.

[0049] The compressor 11, engine turbocharger 12, and air suspension pump 13 can all pressurize the gas. The air supply system 100 provided in this application embodiment can save on component costs and reduce the space occupation caused by the new pressurization unit 1 by making reasonable use of existing devices in the vehicle.

[0050] It is understandable that the compressor 11, the engine supercharger 12, and the air suspension system can be used simultaneously, or one or more of them can be selected according to the actual situation. For example, the engine supercharger 12 can only be activated when the engine is running, and is suitable for providing high-pressure gas when the vehicle engine is running.

[0051] In some embodiments, the compressor 11 can be an integrated air conditioning and air compressor. The compressor 11 can be used solely for air compression, solely for refrigeration compression, or simultaneously for both air compression and refrigeration compression. By employing an integrated compressor, integration can be improved and costs reduced.

[0052] In some embodiments, please refer to Figure 2 The gas supply system 100 also includes an air intake unit 5. One end of the air intake unit 5 is connected to the outside, and the other end is connected to the pressurization unit 1. The air intake unit 5 enables the pressurization unit 1 to connect with the outside. The pressurization unit 1 absorbs outside gas, pressurizes it to form high-pressure gas, and then delivers it to the downstream end.

[0053] In some embodiments, the intake unit 5 includes at least one air conditioning intake unit 51 and an engine intake unit 52.

[0054] The air conditioning intake unit 51 is mainly used to introduce outside air into the vehicle for ventilation purposes. The engine intake unit 52 is mainly used to absorb outside air to provide sufficient air to the engine to support the combustion process. Both the air conditioning intake unit 51 and the engine intake unit 52 are existing intake units 5 in the vehicle. The air supply system 100 provided in this embodiment reduces component costs and saves vehicle space by utilizing the existing air conditioning intake unit 51 and / or engine intake unit 52 in the vehicle.

[0055] Understandably, the intake unit 5 can also be selected according to actual needs. For example, for pure electric vehicles, there is no engine intake unit 52, so air can be drawn in by the air conditioning intake unit 51.

[0056] In some embodiments, please refer to Figure 2 The air supply system 100 also includes a filter unit 6. One end of the filter unit 6 is connected to the air intake unit 5, and the other end is connected to the pressurization unit 1.

[0057] The filter unit 6, located between the air intake unit 5 and the pressurization unit 1, can filter impurities, particles and other pollutants in the air, reduce the damage of impurities to the pressurization unit 1 and improve the reliability of the air supply system 100.

[0058] In some embodiments, please refer to Figure 2The air supply system 100 also includes an oxygen storage unit 7. The oxygen storage unit 7 is adapted to be connected to the oxygen generating unit 3 and is also adapted to at least oxygenate the cabin. The oxygen storage unit 7 can store the oxygen generated by the oxygen generating unit 3, or it can be directly replenished with oxygen by an external oxygen storage device. The oxygen storage unit 7 can directly oxygenate the cabin without activating the oxygen generating unit 3.

[0059] Among them, the oxygen storage unit 7 can directly oxygenate the vehicle's cabin, or it can be connected to the oxygen supply unit to oxygenate the cabin through the oxygen supply unit.

[0060] In some embodiments, the oxygen receiving unit 4 includes at least one of an air conditioning unit, an oxygen mask, and an engine intake unit.

[0061] The vehicle's air conditioning unit supplies gas to the cabin for cooling or heating. Oxygen from the oxygen generator unit 3 and / or the oxygen storage unit 7 is delivered to the cabin via the air conditioning unit, thereby increasing the oxygen concentration inside the vehicle. When the vehicle is traveling in high-altitude environments, supplying oxygen to the cabin through the air conditioning unit can increase the oxygen concentration and alleviate altitude sickness. In special circumstances, if occupants experience hypoxia, they can receive supplemental oxygen through oxygen masks. Furthermore, when increased engine power is needed, or when the vehicle is traveling at high altitudes and the engine's oxygen supply is insufficient, oxygen can be supplied to the engine's air intake unit.

[0062] In some embodiments, please refer to Figure 3 The gas supply system 100 also includes a nitrogen receiving unit 8. The oxygen generating unit 3 is a nitrogen-oxygen separation unit, which is suitable for producing oxygen and nitrogen. The nitrogen receiving unit 8 is connected to the nitrogen-oxygen separation unit and is used to receive the nitrogen produced by the nitrogen-oxygen separation unit.

[0063] A nitrogen-oxygen separation unit achieves oxygen production by separating nitrogen and oxygen in air. In related technologies, nitrogen is typically emitted directly as waste gas during oxygen production via a nitrogen-oxygen separation unit, resulting in ineffective utilization and resource waste. The gas supply unit provided in this application includes both an oxygen receiving unit 4 and a nitrogen receiving unit 8. The oxygen receiving unit 4 utilizes the oxygen produced by the nitrogen-oxygen separation unit, while the nitrogen receiving unit 8 utilizes the nitrogen produced by the nitrogen-oxygen separation unit, thus achieving full utilization of resources.

[0064] In some embodiments, please refer to Figure 3 The gas supply system 100 also includes a nitrogen storage unit 9, which is adapted to be connected to a nitrogen-oxygen separation unit and also adapted to supply nitrogen to the vehicle.

[0065] The nitrogen storage unit 9 can store the nitrogen produced by the nitrogen-oxygen separation unit, or it can be directly replenished with nitrogen by an external nitrogen storage device. The nitrogen storage unit 9 can supply oxygen to the vehicle directly without activating the nitrogen-oxygen separation unit.

[0066] In some embodiments, the nitrogen-receiving unit 8 includes at least one of a battery cooling unit, a tire inflation unit, a fuel tank inflation unit, a thermal runaway cooling unit, an engine intake unit, and a water-floating airbag unit.

[0067] By applying nitrogen to the battery cooling unit, battery cooling can be achieved. Applying nitrogen to the tire inflation unit improves the high-temperature stability of the tires. As an inert gas, nitrogen, when applied to the fuel tank inflation unit, protects the fuel, reduces fuel oxidation, lowers the risk of explosion, and maintains a positive pressure environment inside the fuel tank. As an inert gas, nitrogen, when applied to the thermal runaway cooling unit, can prevent the spread of thermal runaway in the event of a runaway; compared to air, nitrogen provides better protection. The nitrogen receiving unit 8, which includes the engine intake unit, allows for the adjustment of the gas composition in the engine, altering the engine's power output. The buoyancy airbag unit is a device that protects the vehicle from flooding; when the vehicle is submerged, rapid inflation of the buoyancy airbag unit allows the vehicle to float. The nitrogen receiving unit 8, which includes the buoyancy airbag unit, allows for the rapid inflation of nitrogen into the buoyancy airbag unit.

[0068] Secondly, embodiments of this application also provide a vehicle including the air supply system 100 as described above.

[0069] The vehicle provided in this application embodiment has all the beneficial effects of the air supply system 100 as described above, which will not be repeated here.

[0070] In some embodiments, please refer to the vehicle. Figure 4 The vehicle also includes a control system 200 and a human-machine interface system 300. The control system 200 is electrically connected to the air supply system 100 and is used to control the air supply system 100. The human-machine interface system 300 is electrically connected to the control system 200 and is used to receive user commands and feed them back to the control system 200.

[0071] The human-computer interaction system 300, the control system 200 and the gas supply system 100 work together to adjust the working mode of the gas supply system 100 to adapt to different scenario requirements.

[0072] In some embodiments, please refer to Figure 4The vehicle also includes a sensor system 400 and a human vital signs detection system 500. The sensor system 400 is electrically connected to the human-machine interface system 300, and is used to detect vehicle parameters and feed them back to the human-machine interface system 300. The human vital signs detection system is also electrically connected to the human-machine interface system 300, and is used to detect the vital signs of the occupants inside the vehicle and feed them back to the human-machine interface system 300.

[0073] Intelligent control can be achieved through the sensor system 400 and the human vital signs detection system 500.
