[0052] The vehicle-mounted mobile oxygen chamber system provided in this embodiment, the air compression module 2 is arranged under the front cabin hood of the vehicle, the air compression module 2 is isolated from the passenger compartment, and the noise generated by the air compression module 2 (such as the air compressor unit 20) has little effect on the passenger compartment. The oxygen output assembly is arranged in the passenger compartment of the vehicle, and outputs oxygen to the passenger compartment to form a comfortable oxygen-rich environment in the passenger compartment. The air compression module 2 is arranged under the front cabin hood of the vehicle, the nitrogen and oxygen separation module 1 is arranged in the trunk of the vehicle, and the oxygen output assembly is arranged in the passenger compartment of the vehicle. The air compression module 2, the nitrogen and oxygen separation module 1 and the oxygen output assembly are reasonably located and distributed in different positions of the vehicle separately, thereby reducing the impact on the passenger compartment space. The air compression module 2, the nitrogen and oxygen separation module 1 and the oxygen output assembly are all connected to the vehicle's center console 5 for communication. The above three parts are coordinated and controlled by the center console 5, so as to realize the coordinated operation of oxygen production and oxygen supply, and are convenient for the use of the driver and passengers.

[0053] like Figure 1-Figure 4 As shown, optionally, the vehicle-mounted mobile oxygen chamber system further includes an oxygen concentration sensor 6 and a flow control valve. The oxygen concentration sensor 6 is arranged in the passenger compartment and is connected to the vehicle's center console 5 for communication. The oxygen concentration sensor 6 is used to detect the oxygen concentration in the passenger compartment. The flow control valve is used to adjust the oxygen flow output by the nitrogen and oxygen separation module 1. The flow control valve is connected to the vehicle's center console 5 for communication. The driver and passengers can operate the center console 5 to adjust the flow control valve according to the oxygen concentration information output by the center console 5, so as to easily adjust the oxygen content in the passenger compartment.

[0054] In some embodiments, the DC power supply module is used to supply power to the oxygen concentration sensor 6 , the nitrogen and oxygen separation module 1 and the air compression module 2 .

[0055] like Figure 4 and Figure 6 As shown, optionally, the nitrogen oxygen separation module 1 includes a first molecular sieve element 15, a second molecular sieve element 18, a multi-way control valve 17, an oxygen storage tank 11 and a nitrogen exhaust pipe 16, the multi-way control valve 17 is connected to the air compression module 2, the multi-way control valve 17 selectively connects the input end of the first molecular sieve element 15 and the input end of the second molecular sieve element 18, the multi-way control valve 17 is connected to the nitrogen exhaust pipe 16, the output end of the first molecular sieve element 15 and the output end of the second molecular sieve element 18 are both connected to the input end of the oxygen storage tank 11, and the output end of the oxygen storage tank 11 is connected to the oxygen output component.

[0056] In some embodiments, the multi-way control valve 17 is a solenoid valve having four interfaces respectively connected to the first molecular sieve element 15, the second molecular sieve element 18, the nitrogen exhaust pipe 16 and the air compression module 2. The multi-way control valve 17 can control the conduction and blocking of each interface respectively.

[0057] In some embodiments, the first molecular sieve element 15 and the second molecular sieve element 18 can respectively adopt pressure swing adsorption (PSA) gas separation technology to separate oxygen and nitrogen in the air by utilizing the difference in the "adsorption" performance of molecular sieves to different gas molecules.

[0058] In some embodiments, the output end of the nitrogen exhaust pipe 16 extends to the outside of the vehicle, so that the nitrogen is discharged outside the vehicle to avoid affecting the oxygen concentration in the passenger compartment.

[0059] When the nitrogen and oxygen separation module 1 is working, the multi-way control valve 17 is connected to the first molecular sieve element 15 and disconnected from the second molecular sieve element 18. When the pressurized air output by the air compression module 2 enters the molecular sieve bed in the first molecular sieve element 15 through the multi-way control valve 17, the nitrogen is adsorbed and the oxygen is released from the output end of the first molecular sieve element 15 and flows into the oxygen storage tank 11. After the first molecular sieve element 15 is saturated with adsorption, the multi-way control valve 17 is switched to be connected with the second molecular sieve element 18. When connected with the first molecular sieve element 15, the pressurized air enters the second molecular sieve element 18 through the multi-way control valve 17. At this time, the saturated first molecular sieve element 15 discharges nitrogen through the multi-way control valve 17 and the nitrogen exhaust pipe 16, and the process of adsorbing nitrogen and releasing oxygen in the next working cycle is resumed. The first molecular sieve element 15 and the second molecular sieve element 18 alternate with each other, and oxygen continuously enters the oxygen storage tank 11, and then enters the oxygen output component from the oxygen storage tank 11. The oxygen output component diffuses the oxygen into the passenger compartment to increase the oxygen content in the vehicle for breathing by the driver and passengers, and the nitrogen is discharged outside the passenger compartment.

[0060] like Figure 5 and Figure 6As shown, in some embodiments, the nitrogen-oxygen separation module 1 further includes a containing box 112, on the bottom plate in the containing box 112, the first molecular sieve element 15 and the second molecular sieve element 18 are arranged side by side and spaced apart along the width direction of the containing box 112, the oxygen storage tank 11 and the multi-way control valve 17 are arranged between the first molecular sieve element 15 and the second molecular sieve element 18, and the oxygen storage tank 11 and the multi-way control valve 17 are sequentially distributed along the length direction of the containing box 112. An air intake connector 110 and a nitrogen exhaust connector 116 are provided on the box wall of the containing box 112 on one side close to the multi-way control valve 17 in the length direction, and the air intake connector 110 and the nitrogen exhaust connector 116 are both connected to the multi-way control valve 17. An oxygen outlet connector 111 is provided on the box wall of the containing box 112 on one side close to the oxygen storage tank 11 in the length direction. Such an arrangement facilitates the first molecular sieve element 15 and the second molecular sieve element 18 to share the oxygen storage tank 11 and the multi-way control valve 17, and facilitates the air intake connector 110 and the nitrogen exhaust connector 116 to be connected to the multi-way control valve 17. The structure is compact and space-saving, so that the air intake connector 110, the nitrogen exhaust connector 116 and the oxygen outlet connector 111 are distinguished from each other at different positions. In this embodiment, the nitrogen exhaust pipe 16 can be connected to the nitrogen exhaust connector 116, and the air compression module 2 can be connected to the air intake connector 110.

The one-way valve 13 prevents oxygen from flowing back to the oxygen storage tank 11, the flow regulating valve adjusts the output flow and flow rate of the oxygen storage tank 11, and the pressure regulating valve 12 adjusts the pressure of the oxygen storage tank 11. Furthermore, the pressure regulating valve 12, the one-way valve 13 and the flow regulating valve are all arranged in the containing box 112, and are all located between the multi-way control valve 17 and the oxygen storage tank 11, and the structure is compact.
