In particular, for long-distance truck drivers, the in-vehicle oxygen generation function can effectively help them dispel drowsiness, keep a clear mind to drive the vehicle, and avoid the occurrence of traffic accidents. Further, as an important part of the vehicle active suspension system, the air suspension can adjust the stiffness and damping of the suspension in real time according to the motion state of the vehicle and the road conditions, so that the suspension system is in the best shock absorption state, and the vehicle has good comfort under various road conditions.

[0041] Please refer to Figure 1 , which shows a schematic structural diagram of an oxygen generation and suspension air supply system provided by an embodiment of the present application. The technical solutions of the present application will be described in detail below in conjunction with Figure 1 the following.

[0042] An embodiment of the present application provides an oxygen generation and suspension air supply system. As Figure 1 shown, the oxygen generation and suspension air supply system specifically includes an oxygen generation module 1, a suspension air supply module 2 and a control module. Both the oxygen generation module 1 and the suspension air supply module 2 are electrically connected to the control module.

[0043] Among them, the adjustment end of the suspension air supply module 2 is used to connect to the suspension mechanism 3 to be adjusted, the input end of the suspension air supply module 2 is used to connect to the gas storage device 4, and the suspension air supply module 2 is used to respond to the suspension gas adjustment instruction sent by the control module and adjust the gas in the suspension mechanism 3 to be adjusted; the input end of the oxygen generation module 1 is connected to the suspension air supply module 2, the first output end of the oxygen generation module 1 is used to connect to the nitrogen discharge port, the second output end of the oxygen generation module 1 is connected to the vehicle cockpit, and the oxygen generation module 1 is used to respond to the oxygen generation instruction sent by the control module, perform nitrogen discharge treatment on the compressed air output by the suspension air supply module 2 to obtain oxygen, and perform oxygen supply treatment based on the oxygen content in the vehicle cockpit or the breathing state of the user.

[0044] In the embodiments of the present application, the control module is used to control the opening and closing of the devices in the oxygen generation module 1 and the suspension air supply module 2, so as to realize the control operations of oxygen generation and suspension air supply. In a specific embodiment, the control module can receive the vehicle suspension air conditioning demand. Then, when the control module receives the vehicle suspension air conditioning demand, the control module can control the start of the corresponding devices in the suspension air supply module 2, so as to adjust the gas in the suspension mechanism 3 to be adjusted. Furthermore, the adjustment of the gas in the suspension mechanism 3 to be adjusted can raise or lower the vehicle body height, so that the suspension system is in the best shock absorption state, and thus users in the vehicle can have a better sense of comfort under various road conditions.

[0045] Furthermore, the control module can also receive the demand for preparing oxygen. Then, when the control module receives the demand for preparing oxygen, the control module can control the start of the corresponding devices in the oxygen generation module 1 and the air compression unit 21 in the suspension air supply module 2, so as to use the oxygen generation module 1 to perform nitrogen removal treatment on the compressed air output by the air compression unit 21 in the suspension air supply module 2 to obtain oxygen. Furthermore, the integration of oxygen generation and suspension air supply can be realized, thus reducing the production cost. Moreover, the oxygen generation module 1 can also perform oxygen supply treatment based on the oxygen content in the vehicle cockpit or the breathing state of the user, so as to provide multiple oxygen supply methods. Furthermore, the corresponding oxygen supply selection can be made according to the user's demand to realize on-demand oxygen supply, thereby improving the oxygen supply utilization rate.

[0046] In an alternative embodiment, as Figure 1 shown, the suspension air supply module 2 includes an air compression unit 21, a supplementary air switching valve assembly, an exhaust switching valve assembly, and an air valve assembly 22. Among them, the first end of the supplementary air switching valve assembly is connected to the gas storage device 4, the second end of the supplementary air switching valve assembly is connected to the air valve assembly 22, the third end and the fourth end of the supplementary air switching valve assembly are both connected to the air compression unit 21, and the air compression unit 21, the supplementary air switching valve assembly, and the air valve assembly 22 form a closed supplementary air circuit. The closed supplementary air circuit is used to compress the air output by the gas storage device 4 and transmit the compressed air to the suspension mechanism 3 to be adjusted for closed supplementary air supply to the suspension mechanism 3 to be adjusted. The first end of the exhaust switching valve assembly is connected to the gas storage device 4, the second end of the exhaust switching valve assembly is connected to the air valve assembly 22, the third end and the fourth end of the exhaust switching valve assembly are both connected to the air compression unit 21, and the air compression unit 21, the exhaust switching valve assembly, and the air valve assembly 22 form a closed exhaust circuit. The closed exhaust circuit is used to compress the air discharged from the suspension mechanism 3 to be adjusted and transmit the compressed air to the gas storage device 4 for closed exhaust of the suspension mechanism 3 to be adjusted.

[0047] In the embodiment of the present application, the air compression unit 21 is used to compress air to build up the air pressure. Further, during the process of building up the pressure by the air compression unit 21, the gas flow in the pipeline connected to the air compression unit 21 can be driven to realize the suspension air supply process. In some embodiments, such as Figure 1 As shown, the air compression unit 21 includes a motor 211, a plunger pump 212, a first intake check valve 213, a second intake check valve 214, a first exhaust check valve 215, and a second exhaust check valve 216. Among them, the output end of the first intake check valve 213 is connected to the first exhaust check valve 215 through the plunger pump 212, and the output end of the second intake check valve 214 is connected to the second exhaust check valve 216 through the plunger pump 212. The input ends of the first intake check valve 213 and the second intake check valve 214 are both connected to the first air supply switching valve 61 in the air supply switching valve assembly and the first exhaust switching valve 63 in the exhaust switching valve assembly. Specifically, the motor 211 can drive the plunger pump 212 to move to build up the air pressure. The first intake check valve 213 and the second intake check valve 214 serve as the air input ports, and the first exhaust check valve 215 and the second exhaust check valve 216 serve as the compressed air output ports.

[0048] In practical applications, such as Figure 1 As shown, the air compression unit 21 includes a double plunger pump 212. The double plunger pumps 212 are symmetrically arranged on both sides of the motor 211. Further, the symmetrically arranged double plunger pumps 212 can be extended to 3 plunger pumps 212 arranged in a Y shape, or extended to 4 plunger pumps arranged in a cross shape. No specific limitation is made here. It should be noted that the plunger pump 212 can also be a scroll pump or a screw pump, etc.

[0049] In some embodiments, the air replenishing switching valve assembly is used to control the connection between the air storage device 4 and the air compression unit 21, as well as the connection between the air compression unit 21 and the air valve assembly 22. So, when the air replenishing switching valve assembly is in the open state, a closed air replenishing process is performed on the suspension mechanism 3 to be adjusted to raise the vehicle body height. Specifically, the air replenishing switching valve assembly includes a first air replenishing switching valve 61 and a second air replenishing switching valve 62. Among them, the input end of the second air replenishing switching valve 62 is connected to the output end of the air storage device 4, and the output end of the second air replenishing switching valve 62 is respectively connected to the first intake check valve 213 and the second intake check valve 214 in the air compression unit 21. Thus, when the second air replenishing switching valve 62 is in the open state, the air storage device 4 and the air compression unit 21 are in a connected state, so that the air stored in the air storage device 4 can flow into the air compression unit 21 through the pipeline. The input end of the first air replenishing switching valve 61 is connected to the air compression unit 21, and the output end of the first air replenishing switching valve 61 is connected to the suspension mechanism 3 to be adjusted through the air valve assembly 22. Thus, when the first air replenishing switching valve 61 is in the open state, the on-off of the air valves in different air valve assemblies 22 is matched at the same time, so that the air compressed by the air compression unit 21 can sequentially pass through the first air replenishing switching valve 61 and the connected air valves and flow into the corresponding suspension mechanism 3 to be adjusted, so as to perform a closed air replenishing on the suspension mechanism 3 to be adjusted, and then the vehicle body height can be raised to adapt to the road surface environment where the current vehicle is located and improve the riding comfort.

[0050] In practical applications, the air valve assembly 22 is used to control the opening or closing of the passage leading to the suspension mechanism 3 to be adjusted. Specifically, as Figure 1 shown, the air valve assembly 22 includes a first air valve 221, a second air valve 222, a third air valve 223 and a fourth air valve 224, and the suspension mechanism 3 to be adjusted includes a first air spring 31, a second air spring 32, a third air spring 33 and a fourth air spring 34. Among them, the first air valve 221 is connected to the first air spring 31, the second air valve 222 is connected to the second air spring 32, the third air valve 223 is connected to the third air spring 33, and the fourth air valve 224 is connected to the fourth air spring 34. The first air valve 221, the second air valve 222, the third air valve 223 and the fourth air valve 224 are connected in parallel with each other. Thus, by opening the air valves in different air valve assemblies 22, closed inflation for different air springs can be achieved.

[0051] In another specific embodiment, the suspension air supply module 2 further includes an air dryer 28. One end of the air dryer 28 is sequentially connected to the suspension mechanism 3 to be adjusted through a first air replenishment switching valve 61 and an air valve assembly 22, and the other end of the air dryer 28 is connected to the air compression unit 21. The air dryer 28 is used to dry the air. Further, the compressed air output by the air compression unit 21 can be dried by the air dryer 28, so as to ensure that the air flowing into the suspension mechanism 3 to be adjusted is in a dry state, thereby avoiding the occurrence of situations such as the suspension mechanism 3 to be adjusted rusting due to humid air or the rubber components in the suspension mechanism 3 to be adjusted swelling, playing a role in protecting the suspension mechanism 3 to be adjusted.

[0052] Further, when the control module receives the demand for air suspension air replenishment, it can simultaneously control the first air replenishment switching valve 61 and the second air replenishment switching valve 62 to be in the energized state, and control some or all of the air valves in the air valve assembly 22 to be in the energized state according to the air suspension air replenishment demand. Further, the air stored in the air storage device 4 can flow into the air compression unit 21 through the second air replenishment switching valve 62. After the air compression unit 21 compresses the air, it sequentially passes through the air dryer 28, the first air replenishment switching valve 61 and some or all of the air valves in the air valve assembly 22, and enters the corresponding suspension mechanism 3 to be adjusted, so as to perform closed-loop air replenishment on the suspension mechanism 3 to be adjusted.

[0053] In another specific embodiment, the exhaust switching valve assembly is used to control the connection between the air valve assembly 22 and the air compression unit 21, and the connection between the air compression unit 21 and the control air storage device 4. So, when the exhaust switching valve assembly is in the open state, a closed exhaust is performed on the suspension mechanism 3 to be adjusted to reduce the vehicle body height. Specifically, the exhaust switching valve assembly includes a first exhaust switching valve 63 and a second exhaust switching valve 64. Among them, the input end of the first exhaust switching valve 63 is connected to the suspension mechanism 3 to be adjusted through the air valve assembly 22, and the output end of the first exhaust switching valve 63 is connected to the air compression unit 21. Then, when the first exhaust switching valve 63 is in the open state, the on / off of the air valves in different air valve assemblies 22 is simultaneously matched, so that the air in the suspension mechanism 3 to be adjusted flows into the air compression unit 21 through the corresponding air valves and the first exhaust switching valve 63 in sequence, to perform a closed exhaust on the suspension mechanism 3 to be adjusted, and then the vehicle body height can be reduced to adapt to the road surface environment where the current vehicle is located and improve the riding comfort. The input end of the second exhaust switching valve 64 is connected to the first exhaust check valve 215 and the second exhaust check valve 216 in the air compression unit 21 through the air dryer 28, and the output end of the second exhaust switching valve 64 is connected to the output end of the air storage device 4. Then, when the second exhaust switching valve 64 is in the open state, the air compression unit 21 and the air storage device 4 are in a connected state, so that the compressed air in the air compression unit 21 can flow into the air storage device 4 through the air dryer 28 and the second exhaust switching valve 64 for storage.

[0054] Furthermore, when the control module receives the demand for air suspension exhaust, it can simultaneously control the first exhaust switching valve 63 and the second exhaust switching valve 64 to be in the energized state, and control some or all of the air valves in the air valve assembly 22 to be in the energized state according to the air suspension exhaust demand. Then, the air in the suspension mechanism 3 to be adjusted can flow into the air compression unit 21 through the first exhaust switching valve 63. After the air compression unit 21 compresses the air, it enters the air storage device 4 through the air dryer 28 and the second exhaust switching valve 64 in sequence, so as to perform a closed exhaust on the suspension mechanism 3 to be adjusted and transmit the exhausted air to the air storage device 4 for recycling the air.

[0055] Furthermore, by performing closed air replenishment and closed exhaust on the suspension mechanism 3 to be adjusted, the height of the vehicle and the softness and hardness of the suspension can be adjusted, so that the suspension system is in the best shock absorption state, and thus users in the vehicle can have a better sense of comfort under various road conditions.

[0056] In an alternative embodiment, as Figure 1As shown, the suspension air supply module 2 further includes an air filtration unit 23. One end of the air filtration unit 23 is in communication with the atmosphere, and the other end of the air filtration unit 23 is connected to the air compression unit 21. The air filtration unit 23, the air compression unit 21, and the exhaust switching valve assembly form an open air replenishment circuit, which is used to compress the sucked air and transmit the compressed air to the storage device 4 for open air replenishment of the storage device 4.

[0057] In the embodiment of the present application, as Figure 1 shown, the air filtration unit 23 may include an air filter 231, which is used to filter impurities in the air. Specifically, the exhaust switching valve assembly includes a second exhaust switching valve 64. Then, the air filtration unit 23, the air compression unit 21, and the second exhaust switching valve 64 form an open air replenishment circuit. Further, when the control module detects that the gas volume in the storage device 4 is insufficient, it can control the second exhaust switching valve 64 to be in the energized state and control the air compression unit 21 to operate. Then, the motor 211 in the air compression unit 21 drives the plunger pump 212 to operate. Thus, the operation of the plunger pump 212 can suck air through the air filter 231, and then the air compression unit 21 compresses the sucked air. After the air compression unit 21 compresses the air, it enters the storage device 4 through the air dryer 28 and the second exhaust switching valve 64 in sequence, so as to perform open air replenishment on the storage device 4. Further, an automatic air replenishment operation for the storage device 4 can be realized to ensure sufficient air in the storage device 4.

[0058] In an alternative embodiment, as Figure 1 shown, the suspension air supply module 2 further includes a desiccant regeneration unit and an exhaust valve 7. The first end of the desiccant regeneration unit is connected to the storage device 4 through the exhaust switching valve assembly, the second end of the desiccant regeneration unit is connected to the air compression unit 21, the third end of the desiccant regeneration unit is connected to one end of the exhaust valve 7, and the other end of the exhaust valve 7 is in communication with the atmosphere. The exhaust switching valve assembly, the desiccant regeneration unit, and the exhaust valve 7 form a desiccant regeneration circuit.

[0059] In the embodiment of the present application, the desiccant regeneration unit includes an air dryer 28 and a throttle check valve 29. Among them, the throttle check valve 29 includes a fourth one-way valve 291 and a throttle valve 292. One end of the air dryer 28 is connected to the output end of the air compression unit 21, and the other end of the air dryer 28 is respectively connected to the input end of the fourth one-way valve 291 and one end of the throttle valve 292. The output end of the fourth one-way valve 291 and the other end of the throttle valve 292 are both connected to the air storage device 4 through the second exhaust switching valve 64 in the exhaust switching valve assembly. The air dryer 28 is used to dry the compressed air output by the air compression unit 21. The fourth one-way valve 291 allows forward gas flow and throttles reverse gas flow. Therefore, the fourth one-way valve 291 does not affect the gas flow between the air compression unit 21 and the exhaust switching valve assembly. The throttle valve 292 can flow bidirectionally. Thus, the second exhaust switching valve 64, the throttle valve 292, the air dryer 28, and the exhaust valve 7 form a desiccant regeneration loop. By using the desiccant regeneration loop, the moisture in the saturated desiccant device can be removed to realize the regeneration of the desiccant.

[0060] Specifically, when the control module detects that the desiccant in the air dryer 28 is in a saturated state, the control module can simultaneously control the second exhaust switching valve 64 and the exhaust valve 7 to be in the energized state. Then, the air stored in the air storage device 4 can flow through the second exhaust switching valve 64, the throttle valve 292, the air dryer 28, and the exhaust valve 7 in sequence and flow into the atmosphere. During the air flow process, the air can carry away the moisture absorbed by the desiccant in the air dryer 28, thereby realizing the regeneration of the desiccant.

[0061] In another specific embodiment, the suspension air supply module 2 further includes a third pressure detection device 24, a third one-way valve 25, a power limiting valve 26, and a manual exhaust bolt 27. The third pressure detection device 24 is arranged between the air supplement switching valve assembly or the exhaust switching valve assembly and the air valve assembly 22. The third pressure detection device 24 can be a temperature and pressure sensor. Thus, the third pressure detection device 24 can be used to detect the pressure and temperature of the connecting pipeline between the air supplement switching valve assembly or the exhaust switching valve assembly and the air valve assembly 22. The input end of the third one-way valve 25 is connected to the air filter 231, and the output end of the third one-way valve 25 is connected to the air compression unit 21. By setting the third one-way valve 25, the air flowing into the air compression unit 21 can be prevented from flowing out of the air filter 231, thereby improving the utilization rate of air. The power limiting valve 26 is used to limit the power of the air compression unit 21. The input end of the manual exhaust bolt 27 is connected to the air compression unit 21 through the air dryer 28 and the throttle check valve 29, and the output end of the manual exhaust bolt 27 is communicated with the atmosphere. It is used to discharge the high-pressure air in the air compression unit 21 under special working conditions, thereby ensuring the stability of the suspension air supply module.

[0062] In an alternative embodiment, as Figure 1 shown, the oxygen generation module 1 includes an oxygen generation unit, a desorption and nitrogen discharge unit, an oxygen collection unit 11, and an oxygen supply unit 12; wherein, the input end of the oxygen generation unit is connected to the air compression unit 21 in the suspension air supply module 2, the first output end of the oxygen generation unit is connected to the input end of the oxygen collection unit 11, and the oxygen generation unit is configured to separate nitrogen and oxygen from the high-pressure air transmitted by the air compression unit 21 and transmit the separated oxygen to the oxygen collection unit 11; the second output end of the oxygen generation unit is connected to one end of the desorption and nitrogen discharge unit, and the other end of the desorption and nitrogen discharge unit is connected to the nitrogen discharge port. The desorption and nitrogen discharge unit is configured to perform nitrogen discharge treatment on the nitrogen separated by the oxygen generation unit; the output end of the oxygen collection unit 11 is connected to the input end of the oxygen supply unit 12, and the output end of the oxygen supply unit 12 is connected to the vehicle cockpit. The oxygen supply unit 12 is configured to perform oxygen supply treatment based on the detected oxygen content in the vehicle cockpit or the detected breathing state of the user.

[0063] In the embodiment of the present application, by providing the oxygen generation unit, the desorption and nitrogen discharge unit, the oxygen collection unit 11, and the oxygen supply unit 12, the oxygen generation unit is used to separate nitrogen and oxygen from the high-pressure air transmitted by the air compression unit 21 and transmit the separated oxygen to the oxygen collection unit 11 to implement the oxygen generation operation. Further, the desorption and nitrogen discharge unit can be used to perform nitrogen discharge treatment on the nitrogen separated by the oxygen generation unit, so as to avoid the occurrence of the oxygen generation unit being in a supersaturated state, ensuring the oxygen generation efficiency of the oxygen generation unit. Still further, the oxygen supply unit 12 can be used to perform oxygen supply treatment based on the detected oxygen content in the vehicle cockpit or the detected breathing state of the user, so as to provide multiple oxygen supply methods, and then corresponding oxygen supply selection can be made according to the user's needs to achieve oxygen supply on demand, thereby improving the oxygen supply utilization rate.

[0064] In a specific embodiment, as Figure 1As shown in the figure, the oxygen generation unit includes a first oxygen generation sub-unit 13 and a second oxygen generation sub-unit 14. Among them, the input ends of the first oxygen generation sub-unit 13 and the second oxygen generation sub-unit 14 are both connected to the air compression unit 21. The first output ends of the first oxygen generation sub-unit 13 and the second oxygen generation sub-unit 14 are both connected to the oxygen collection unit 11. The first output end of the first oxygen generation sub-unit 13 is also connected to the first output end of the second oxygen generation sub-unit 14. The second output ends of the first oxygen generation sub-unit 13 and the second oxygen generation sub-unit 14 are both connected to the desorption and nitrogen discharge unit. When the first nitrogen discharge valve 15 in the desorption and nitrogen discharge unit is in the open state, the high-pressure air output by the air compression unit 21 is transmitted to the first oxygen generation sub-unit 13 through the second oxygen generation sub-unit 14 to backflush the first oxygen generation sub-unit 13, so that the nitrogen in the first oxygen generation sub-unit 13 is transmitted to the nitrogen discharge port through the first nitrogen discharge valve 15; or when the second nitrogen discharge valve 16 in the desorption and nitrogen discharge unit is in the open state, the high-pressure air output by the air compression unit 21 is transmitted to the second oxygen generation sub-unit 14 through the first oxygen generation sub-unit 13 to backflush the second oxygen generation sub-unit 14, so that the nitrogen in the second oxygen generation sub-unit 14 is transmitted to the nitrogen discharge port through the second nitrogen discharge valve 16.

[0065] In the embodiment of the present application, both the first oxygen generation sub-unit 13 and the second oxygen generation sub-unit 14 are used to generate oxygen. Specifically, the first oxygen generation sub-unit 13 is used to separate nitrogen and oxygen from the high-pressure air transmitted by the air compression unit 21 and transmit the separated oxygen to the oxygen collection unit 11 to realize the generation of oxygen. Similarly, the second oxygen generation sub-unit 14 is also used to separate nitrogen and oxygen from the high-pressure air transmitted by the air compression unit 21 and transmit the separated oxygen to the oxygen collection unit 11 to realize the generation of oxygen.

[0066] In actual applications, when the control module receives the demand for generating oxygen, it starts the air compression unit 21 to suck air through the air filter 231 connected to the air compression unit 21. Then, the air compression unit 21 compresses the sucked air, and the air compression unit 21 transmits the compressed high-pressure air to the first oxygen generation sub-unit 13 and the second oxygen generation sub-unit 14 so that the first oxygen generation sub-unit 13 or the second oxygen generation sub-unit 14 can generate oxygen. Thus, the oxygen generation module 1 and the suspension air supply module 2 can share one air compression unit 21 to improve the utilization rate of the air compression unit 21.

[0067] In a specific embodiment, such as Figure 1As shown, the first oxygen generation sub-unit 13 includes a first switching valve 131 and a first molecular sieve tank 132, and the second oxygen generation sub-unit 14 includes a second switching valve 141 and a second molecular sieve tank 142. Among them, one end of the first switching valve 131 is connected to the output end of the air compression unit 21, the other end of the first switching valve 131 is connected to the input end of the first molecular sieve tank 132, the output end of the first molecular sieve tank 132 is respectively connected to the output end of the second molecular sieve tank 142 and the input end of the oxygen collection unit 11, and the input end of the first molecular sieve tank 132 is also connected to the first nitrogen discharge valve 15 in the desorption and nitrogen discharge unit; one end of the second switching valve 141 is connected to the output end of the air compression unit 21, the other end of the second switching valve 141 is connected to the input end of the second molecular sieve tank 142, the output end of the second molecular sieve tank 142 is respectively connected to the output end of the first molecular sieve tank 132 and the input end of the oxygen collection unit 11, and the input end of the second molecular sieve tank 142 is also connected to the second nitrogen discharge valve 16 in the desorption and nitrogen discharge unit.

[0068] Specifically, the first switching valve 131 can control the communication state between the air compression unit 21 and the first oxygen generation sub-unit 13. The first molecular sieve tank 132 is used for separating nitrogen and oxygen from the high-pressure air transmitted by the air compression unit 21 and transmitting the separated oxygen to the oxygen collection unit 11. Among them, the principle of nitrogen-oxygen separation by the first molecular sieve tank 132 is that the first molecular sieve tank 132 contains molecular sieves, and its molecular sieves can adsorb nitrogen in the air and pass oxygen in the air, thereby realizing the separation of nitrogen and oxygen. The screened oxygen is stored in the oxygen collection unit 11. It can be understood that the molecules of nitrogen are larger and nitrogen cannot pass through the molecular sieves in the first molecular sieve tank 132, so nitrogen is adsorbed on the molecular sieves in the first molecular sieve tank 132, while the molecules of oxygen are smaller and can pass through the molecular sieves in the first molecular sieve tank 132. Then, the oxygen passing through the first molecular sieve tank 132 is transmitted to the oxygen collection unit 11 for oxygen storage.

[0069] Similarly, the second switching valve 141 can control the communication state between the air compression unit 21 and the second oxygen generation sub-unit 14. The second molecular sieve tank 142 is used to separate nitrogen and oxygen from the high-pressure air transmitted by the air compression unit 21 and transmit the separated oxygen to the oxygen collection unit 11. The principle of nitrogen-oxygen separation in the second molecular sieve tank 142 is that the second molecular sieve tank 142 contains molecular sieves, which can adsorb nitrogen in the air and allow oxygen in the air to pass through, thereby realizing the separation of nitrogen and oxygen. The screened oxygen is stored in the oxygen collection unit 11. It can be understood that the molecules of nitrogen are larger and nitrogen cannot pass through the molecular sieves in the second molecular sieve tank 142, so nitrogen is adsorbed on the molecular sieves in the second molecular sieve tank 142, while the molecules of oxygen are smaller and can pass through the molecular sieves in the second molecular sieve tank 142. Then, the oxygen passing through the second molecular sieve tank 142 is transmitted to the oxygen collection unit 11 for oxygen storage.

[0070] It should be noted that the first oxygen generation sub-unit 13 and the second oxygen generation sub-unit 14 do not prepare oxygen synchronously. That is to say, when the first oxygen generation sub-unit 13 prepares oxygen, the second oxygen generation sub-unit 14 does not prepare oxygen. Or, when the second oxygen generation sub-unit 14 prepares oxygen, the first oxygen generation sub-unit 13 does not prepare oxygen. This can avoid the efficiency of desorbing and discharging nitrogen from the second oxygen generation sub-unit 14 by the first oxygen generation sub-unit 13 and the efficiency of desorbing and discharging nitrogen from the first oxygen generation sub-unit 13 by the second oxygen generation sub-unit 14 in the subsequent process.

[0071] In a specific embodiment, as Figure 1 shown, the desorbing and discharging nitrogen unit includes a first nitrogen discharge valve 15, a second nitrogen discharge valve 16, and a silencing unit 17. Among them, the input end of the first nitrogen discharge valve 15 is connected to the first oxygen generation sub-unit 13, the output end of the first nitrogen discharge valve 15 is connected to the nitrogen discharge port through the silencing unit 17, the input end of the second nitrogen discharge valve 16 is connected to the second oxygen generation sub-unit 14, and the output end of the second nitrogen discharge valve 16 is connected to the nitrogen discharge port through the silencing unit 17. The silencing unit 17 is used to absorb the noise generated during the nitrogen discharge process of the first oxygen generation sub-unit 13 and the second oxygen generation sub-unit 14.

[0072] In the embodiment of the present application, when the control module detects that the nitrogen adsorbed by the second molecular sieve tank 142 reaches the preset amount, during the process of preparing oxygen by using the first oxygen generation sub-unit 13, the second nitrogen discharge valve 16 can be controlled to be in the energized state. Further, a communication state is formed among the first molecular sieve tank 132, the second molecular sieve tank 142, the second nitrogen discharge valve 16, and the silencing unit 17. Then, under the action of the pressure difference, the oxygen separated from the high-pressure air transmitted by the air compression unit 21 through the first molecular sieve tank 132 is transmitted to the second molecular sieve tank 142 to backflush the second molecular sieve tank 142. As a result, the nitrogen adsorbed in the second molecular sieve tank 142 is blown away by the high-pressure oxygen, and successively flows through the second nitrogen discharge valve 16 and the silencing unit 17 into the nitrogen discharge port and is discharged from the nitrogen discharge port. Further, the desorption and nitrogen discharge of the second molecular sieve tank 142 can be realized, thereby avoiding the situation that the second molecular sieve tank 142 is blocked due to excessive adsorbed nitrogen, and improving the oxygen generation efficiency of the second oxygen generation sub-unit 14.

[0073] Further, when the control module detects that the nitrogen adsorbed by the first molecular sieve tank 132 reaches the preset amount, during the process of preparing oxygen by using the second oxygen generation sub-unit 14, the first nitrogen discharge valve 15 can be controlled to be in the energized state. Further, a communication state is formed among the second molecular sieve tank 142, the first molecular sieve tank 132, the first nitrogen discharge valve 15, and the silencing unit 17. Then, under the action of the pressure difference, the oxygen separated from the high-pressure air transmitted by the air compression unit 21 through the second molecular sieve tank 142 is transmitted to the first molecular sieve tank 132 to backflush the first molecular sieve tank 132. As a result, the nitrogen adsorbed in the first molecular sieve tank 132 is blown away by the high-pressure oxygen, and successively flows through the first nitrogen discharge valve 15 and the silencing unit 17 into the nitrogen discharge port and is discharged from the nitrogen discharge port. Further, the desorption and nitrogen discharge of the first molecular sieve tank 132 can be realized, thereby avoiding the situation that the first molecular sieve tank 132 is blocked due to excessive adsorbed nitrogen, and improving the oxygen generation efficiency of the first oxygen generation sub-unit 13.

[0074] Furthermore, when the first nitrogen discharge valve 15 in the desorption and nitrogen discharge unit is in the open state, the high-pressure air output by the air compression unit 21 is transmitted to the first oxygen generation sub-unit 13 through the second oxygen generation sub-unit 14 to backflush the first oxygen generation sub-unit 13. And when the second nitrogen discharge valve 16 in the desorption and nitrogen discharge unit is in the open state, the high-pressure air output by the air compression unit 21 is transmitted to the second oxygen generation sub-unit 14 through the first oxygen generation sub-unit 13 to backflush the second oxygen generation sub-unit 14. Further, the mutual desorption and nitrogen discharge operation between the first oxygen generation sub-unit 13 and the second oxygen generation sub-unit 14 can be realized, thereby improving the oxygen generation efficiency, and there is no need to add additional devices for nitrogen discharge operation, reducing the production cost.

[0075] In practical applications, the oxygen collection unit 11 includes a second one-way valve 111, a second pressure detection device 112, and an oxygen collector 113. Among them, the input end of the second one-way valve 111 is respectively connected to the output ends of the first molecular sieve tank 132 and the second molecular sieve tank 142. The output end of the second one-way valve 111 is successively connected to the second pressure detection device 112 and the oxygen collector 113. Specifically, the function of the second one-way valve 111 is to prevent the oxygen in the oxygen collector 113 from flowing back to the first molecular sieve tank 132 and the second molecular sieve tank 142, thereby improving the oxygen collection efficiency. The second pressure detection device 112 can be a pressure sensor, which is used to detect the pressure of the oxygen collector 113. Furthermore, in the case where the pressure in the oxygen collector 113 is detected to be greater than a preset threshold, shutdown protection is performed to ensure the stability and reliability of the oxygen generation process. The oxygen collector 113 is used to buffer or store oxygen so as to output oxygen externally when oxygen supply is required.

[0076] In an alternative embodiment, as Figure 1 shown, the oxygen supply unit 12 includes a first oxygen supply sub-unit 121 and a second oxygen supply sub-unit 122; among them, the input end of the first oxygen supply sub-unit 121 is connected to the output end of the oxygen collection unit 11, the output end of the first oxygen supply sub-unit 121 is connected to the vehicle cockpit, and the first oxygen supply sub-unit 121 is used to supply oxygen to the vehicle cockpit when the oxygen content in the vehicle cockpit is less than a preset oxygen content threshold; the input end of the second oxygen supply sub-unit 122 is connected to the output end of the oxygen collection unit 11, the output end of the second oxygen supply sub-unit 122 is connected to the nasal inhalation device 5 in the vehicle cockpit, the first oxygen supply sub-unit 121 and the second oxygen supply sub-unit 122 are connected in parallel, and the second oxygen supply sub-unit 122 is used to detect the breathing state of the user in the vehicle cockpit and supply oxygen to the user when the detected breathing state of the user meets a preset condition.

[0077] In the embodiments of the present application, by setting the first oxygen supply sub-unit 121, a diffused oxygen supply mode can be realized. Specifically, when the control module detects that the oxygen content in the vehicle cockpit is less than the preset oxygen content threshold, the first oxygen supply sub-unit 121 is started. Then, the oxygen in the oxygen collector 113 can supply oxygen to the vehicle cockpit, thereby realizing a diffused oxygen supply mode and making the vehicle cockpit in an oxygen-rich state. In another specific embodiment, by setting the second oxygen supply sub-unit 122, a nasal inhalation oxygen supply mode can be realized. Specifically, when the second oxygen supply sub-unit 122 detects that the breathing state of the user meets the preset condition, the detected oxygen supply demand is sent to the control module, so that the control module can open the first oxygen supply control valve 1221 in the second oxygen supply sub-unit 122, thereby realizing on-demand oxygen supply and improving the oxygen supply utilization rate.

[0078] In a specific embodiment, as Figure 1 shown, the first oxygen supply subunit 121 includes a second oxygen supply control valve 1211. Among them, the second oxygen supply control valve 1211 can be a switching valve, which is used to control the connection state between the oxygen collector 113 in the oxygen collection unit 11 and the vehicle cockpit. Furthermore, when the control module detects that the oxygen content in the vehicle cockpit is less than the preset oxygen content threshold, the second oxygen supply control valve 1211 is activated. Then, the oxygen in the oxygen collector 113 can supply oxygen to the vehicle cockpit through the second oxygen supply control valve 1211, thereby realizing a diffused oxygen supply mode and making the vehicle cockpit in an oxygen-rich state.

[0079] In a specific embodiment, as Figure 1 shown, the second oxygen supply subunit 122 includes a first oxygen supply control valve 1221, a first one-way valve 1222, and a first pressure detection device 1223. Among them, the input end of the first oxygen supply control valve 1221 is connected to the output end of the oxygen collection unit 11, the output end of the first oxygen supply control valve 1221 is connected to the input end of the first one-way valve 1222, the output end of the first one-way valve 1222 is connected to the nasal inhalation device 5, and the first pressure detection device 1223 is connected to the pipeline between the nasal inhalation device 5 and the first one-way valve 1222.

[0080] In the embodiment of the present application, the first oxygen supply control valve 1221 can be a switching valve, which is used to control the connection state between the oxygen collector 113 and the nasal inhalation device 5. The first one-way valve 1222 is arranged between the first oxygen supply control valve 1221 and the nasal inhalation device 5, so as to prevent the waste gas exhaled by the user from returning to the oxygen collector 113 in the nasal inhalation mode and polluting the gas in the oxygen collector 113. The first pressure detection device 1223 is connected to the pipeline between the nasal inhalation device 5 and the first one-way valve 1222, and is used to detect the breathing state of the user, so as to control the opening and closing state of the first oxygen supply control valve 1221 according to the breathing state of the user to realize on-demand oxygen supply, thereby improving the oxygen supply utilization rate.

[0081] It should be noted that the oxygen supply unit 12 and the oxygen generation module 1 can operate synchronously. That is to say, during the oxygen supply process of the oxygen supply unit 12, the oxygen generation module 1 can operate synchronously to supplement oxygen to the oxygen collector 113, so as to ensure that the oxygen in the oxygen collector 113 is sufficient.

[0082] In a specific embodiment, the execution priority of the suspension air supply module 2 is higher than that of the oxygen generation module 1. That is to say, when the control module receives an oxygen generation demand, it first identifies whether the suspension air supply module 2 is performing closed-loop air replenishment, closed-loop air exhaust, or open-loop air replenishment. If it is identified that the suspension air supply module 2 is performing closed-loop air replenishment, closed-loop air exhaust, or open-loop air replenishment, then when the suspension air supply module 2 completes closed-loop air replenishment, closed-loop air exhaust, or open-loop air replenishment, the oxygen generation module 1 is started to generate oxygen to ensure the smooth execution of the suspension air supply module 2. It should be noted that if it is identified that the suspension air supply module 2 is performing desiccant regeneration, oxygen can be preferably generated, and after the oxygen generation is completed, the desiccant regeneration operation is performed.

[0083] Further, when the oxygen generation and suspension air supply system is performing oxygen generation operation and the control module monitors that there is a demand for closed-loop air replenishment, closed-loop air exhaust, or open-loop air replenishment, the oxygen generation operation of the oxygen generation module 1 is suspended. After the closed-loop air replenishment, closed-loop air exhaust, or open-loop air replenishment is completed, the oxygen generation operation of the oxygen generation module 1 is resumed, thereby ensuring the smooth progress of the suspension air supply module 2.

[0084] As can be seen from the above technical solutions of the embodiments of the present application, the following technical effects are achieved:

[0085] By setting an oxygen generation module, a suspension air supply module, and a control module, the present application can use the suspension air supply module to respond to the suspension gas regulation instruction sent by the control module to regulate the gas in the suspension mechanism to be regulated, and use the oxygen generation module to respond to the oxygen generation instruction sent by the control module to perform nitrogen removal treatment on the compressed air output by the suspension air supply module to obtain oxygen. Thus, the integration of oxygen generation and suspension air supply can be realized, reducing production costs. At the same time, oxygen supply treatment can also be performed based on the oxygen content in the vehicle cockpit or the breathing state of the user to provide multiple oxygen supply methods, and then corresponding oxygen supply selection can be made according to the user's needs to achieve on-demand oxygen supply, thereby improving the oxygen utilization rate.
