[0031] The embodiments of the present invention will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention will be described in detail below.

[0032] Reference below Figure 1-Figure 3 The vehicle-mounted oxygen production system and the vehicle according to the embodiments of the present invention are described.

[0033] like Figure 1 As shown, the vehicle-mounted oxygen production system includes an air tank 1, an air suspension system, an oxygen concentrator 3, a tire pressure system, and a controller 4. The air suspension system includes an air spring 2, which is connected to the air tank 1. The oxygen concentrator 3 is connected to the air tank 1 and has an exhaust gas discharge path 301. The tire pressure system is connected to the exhaust gas discharge path 301. The controller 4 is electrically connected to the air suspension system, oxygen concentrator 3, and tire pressure system to control the opening and closing of the oxygen concentrator 3 and the inflation and deflation of the air suspension system and tire pressure system.

[0034] Specifically, when the user turns on the oxygen generator function, the air in the air tank 1 enters the oxygen generator 3. The oxygen generated by the oxygen generator 3 is used to supply the cockpit. Figure 2 , can be blown out through the air outlet 23 in the cockpit, and the waste gas such as nitrogen in the air is used as a supplementary air source for the tire pressure system to adjust the air pressure in the tire pressure system.

[0035] In some embodiments, the controller 4 may be a vehicle electronic control module, ECU for short.

[0036] Therefore, according to the vehicle-mounted oxygen generating system of an embodiment of the present invention, the air spring 2 and the oxygen generator 3 share an air intake source, and the air intake source of the tire pressure system comes from the waste gas such as nitrogen generated by the oxygen generator 3. This not only makes effective use of the waste gas of the oxygen generator 3, but also integrates multiple air intake sources to form a common air source system, greatly reducing the number of components and space occupancy, and facilitating the space layout of the entire vehicle.

[0037] Furthermore, the oxygen concentrator 3 includes: an exhaust gas tank 302, which is arranged on the exhaust gas exhaust path 301, and the two ends of the exhaust gas exhaust path 301 are an exhaust gas inlet and an exhaust gas outlet respectively, and the tire pressure system is connected to the exhaust gas exhaust path 301 between the exhaust gas tank 302 and the exhaust gas outlet.

[0038] With this arrangement, the exhaust gas generated by the oxygen generator 3 enters the exhaust gas exhaust path 301 through the exhaust gas inlet, and the exhaust gas is stored by the exhaust gas tank 302. When the air pressure in the exhaust gas tank 302 is sufficient, gases such as nitrogen are discharged out of the vehicle through the exhaust gas outlet. In addition, due to the high temperature in summer or the drop in atmospheric pressure in high-altitude areas, the tire pressure of the tire 7 will increase. Also, the low temperature in winter will cause the tire pressure of the tire 7 to drop. All of the above situations will affect the life of the tire 7, vehicle performance and driving safety. Therefore, the controller 4 can regulate the exhaust gas tank 302 to inflate the tire pressure system in time or regulate the tire pressure system to deflate, so that the tire pressure of the tire 7 is always kept within a safe range to meet the needs of most driving scenarios.

[0039] Furthermore, the tire pressure system includes: at least two first air paths 5 , a tire 7 and a first detection module 8 . The first air path 5 is connected to the exhaust gas discharge path 301 through a first control valve 6 , and the first air path 5 is in communication with at least one tire 7 .

[0040] The first detection module 8 is used to detect the pressure and / or temperature of the tire 7. The first detection module 8 is electrically connected to the controller 4. The controller 4 is configured to determine the working condition of the tire 7 based on the received pressure value and / or temperature value of any tire 7 to control the opening and closing of the first control valve 6.

[0041] With this arrangement, the controller 4 determines the operating condition of the tire 7 based on the temperature and pressure data. When the pressure and / or temperature of the tire 7 is not within the normal preset range under the operating condition, the controller 4 controls the first control valve 6 to open, so that the first air path 5 is connected to the exhaust gas exhaust path 301 to inflate or deflate the tire 7, thereby ensuring that the tire pressure of the tire 7 is always maintained within the range of optimal performance and safety.

[0042] In some embodiments, the tire pressure system may include two first air circuits 5 , one first air circuit 5 connected to the front wheel, and the other first air circuit 5 connected to the rear wheel. Alternatively, the two first air circuits 5 are respectively connected to the tires 7 on the same side.

[0043] Furthermore, the on-board oxygen production system also includes: a second control valve 9, the second control valve 9 has a first valve port, a second valve port and a third valve port, the first valve port is connected to the air outlet of the exhaust gas tank 302, the second valve port is connected to the air inlet of the tire pressure system, and the third valve port is connected to the exhaust gas outlet. The first valve port and the second valve port are selectively connected, the first valve port and the third valve port are selectively connected, and the second valve port and the third valve port are selectively connected. The controller 4 is electrically connected to the second control valve 9.

[0044] With this arrangement, when the first and second valve ports are connected, exhaust gas from the exhaust tank 302 can enter the tire pressure system, inflating the tire pressure system. When the exhaust tank 302 has sufficient pressure, the first and third valve ports are connected, allowing excess nitrogen and other gases to be discharged from the vehicle. When the second and third valve ports are connected, the tire pressure system can be deflated.

[0045] Furthermore, the controller 4 is further configured as follows: when the pressure value received by any tire 7 is lower than a first preset pressure value, the first control valve 6 of the first air circuit 5 connected to the tire 7 is opened, and the first valve port and the second valve port are connected; when the pressure value received by any tire 7 is higher than a second preset pressure value, the first control valve 6 of the first air circuit 5 connected to the tire 7 is opened, and the second valve port and the third valve port are connected.

[0046] With this configuration, when the vehicle is in a certain operating condition, that condition has a corresponding preset tire pressure range, namely, a range within a first preset pressure value and a second preset pressure value. When the pressure of any tire 7 falls below the first preset pressure value, the first control valve 6 opens, and the first valve port and the second valve port are connected to inflate the tire 7. When it is detected that the tire pressure of the tire 7 has reached the preset pressure range, the first control valve 6 closes, cutting off the connection between the first valve port and the second valve port, thereby completing the tire 7 inflation process. Similarly, when the pressure of any tire 7 rises above the second preset pressure value, the first control valve 6 opens, and the second valve port and the third valve port are connected to deflate the tire 7. Once the tire pressure of the tire 7 reaches the preset pressure range, the first control valve 6 closes, cutting off the connection between the second valve port and the third valve port, thereby completing the tire 7 deflation process.

[0047] Further, see Figure 2 As shown, the tire pressure system includes: a drive shaft 10, a first air channel is formed in the drive shaft 10, and the first air channel is connected to the exhaust gas exhaust path 301 through a first pipeline; a hub cover 11, the hub cover 11 is sealed at the end of the drive shaft 10, and a second air channel connected to the first air channel is formed in the hub cover 11, and the second air channel is connected to the inflation port of the tire 7 through a second pipeline. The first pipeline, the first air channel, the second air channel and the second pipeline constitute the first air path 5.

[0048] With this configuration, first control valve 6 allows nitrogen and other gases in exhaust tank 302 to enter the first pipeline, then through the first air passage of drive shaft 10 into the second air passage of hubcap 11, and then through the second pipeline into the inner tube of tire 7. In other words, first air passage 5 is organized as "first pipeline - first air passage of drive shaft 10 - second air passage of hubcap 11 - second pipeline."

[0049] According to some specific embodiments of the present invention, the first detection module 8 includes: a first sensor and a second sensor, the first sensor and the second sensor are arranged on the tire 7, the first sensor is used to detect the pressure of the tire 7, and the second sensor is used to detect the temperature of the tire 7.

[0050] With this arrangement, the first sensor and the second sensor are electrically connected to the controller 4 respectively, and the controller 4 can adjust the tire pressure system in real time according to the pressure value detected by the first sensor and / or the temperature value detected by the second sensor.

[0051] Furthermore, the oxygen concentrator 3 also includes: a third sensor 12 for detecting the pressure in the waste gas tank 302. The third sensor 12 is electrically connected to the controller 4. The controller 4 is configured to control the start and stop of the oxygen concentrator 3 according to the received pressure value in the waste gas tank 302.

[0052] With this configuration, when the third sensor 12 detects insufficient air pressure in the exhaust gas tank 302, the controller 4 controls the oxygen concentrator 3 to activate its oxygen production function to replenish the air pressure in the exhaust gas tank 302. When the air pressure in the exhaust gas tank 302 is sufficient, the oxygen concentrator 3 is deactivated. This ensures that sufficient nitrogen is provided when the tire pressure system requires it, improving the efficiency of the tire pressure system's response.

[0053] Furthermore, the air suspension system includes: a fourth sensor 13 for detecting the height of the vehicle body relative to the ground, the fourth sensor 13 is electrically connected to the controller 4, and the controller 4 is configured to control the inflation and deflation of the air spring 2 according to the received vehicle body height value.

[0054] With such a configuration, the controller 4 will open the channel between the air storage tank 1 and the air spring 2 based on the vehicle body height signal received from the fourth sensor 13. This will allow air to enter the air spring 2, and the volume of the air spring 2 will increase after inflation, thereby raising the vehicle body. When the vehicle body height needs to be lowered, the controller 4 will open the exhaust port on the air spring 2, and rely on the vehicle body's own weight to discharge the gas in the air spring 2 out of the vehicle, thereby maintaining the vehicle body at an appropriate height and improving driving comfort and passability.

[0055] Furthermore, the on-board oxygen generation system further includes: an air compressor 14 and a fifth sensor 15. The fifth sensor 15 is used to detect the pressure in the air storage tank 1. The controller 4 is electrically connected to the fifth sensor 15 and the compressor, respectively. The controller 4 is configured to control the opening of the air compressor according to the received pressure value in the air storage tank 1.

[0056] With this arrangement, when the air pressure in the air storage tank 1 is insufficient, the controller 4 will automatically turn on the air compressor 14 to allow air to enter the air storage tank 1 to replenish the gas and ensure sufficient air supply. When the fifth sensor 15 detects that the air pressure in the air storage tank 1 is sufficient, the controller 4 will automatically turn off the air compressor 14. Figure 2 As shown, the air compressor 14 inhales external air through the air inlet 24 , and the external air passes through the air compressor 14 to form high-pressure gas, which is then stored in the air storage tank 1 .

[0057] Furthermore, the oxygen concentrator 3 further includes a molecular sieve filter device 303 and an oxygen tank 306. The air inlet of the molecular sieve filter device 303 is connected to the air storage tank 1, the exhaust gas outlet of the molecular sieve filter device 303 is connected to the exhaust gas discharge path 301, and the oxygen tank 306 is connected to the oxygen outlet of the molecular sieve filter device 303.

[0058] With such an arrangement, the air in the air storage tank 1 enters the interior of the molecular sieve filter device 303 through the air inlet of the molecular sieve filter device 303. After the molecular sieve filter device 303 works, the oxygen in the air is stored in the oxygen tank 306, and gases such as nitrogen enter the exhaust gas discharge path 301 to be used as a supplementary air source for the tire pressure system.

[0059] According to some specific embodiments of the present invention, the molecular sieve filtration device 303 includes: a first molecular sieve adsorption tower 304 and a second molecular sieve adsorption tower 305, the first molecular sieve adsorption tower 304 and the second molecular sieve adsorption tower 305 are interconnected, and the first molecular sieve adsorption tower 304 and the second molecular sieve adsorption tower 305 are both connected to the oxygen tank 306. In addition, the on-board oxygen production system also includes: a third control valve 16, the third control valve 16 is respectively connected to the air storage tank 1, the first molecular sieve adsorption tower 304, the second molecular sieve adsorption tower 305 and the exhaust gas exhaust path 301, and the first molecular sieve adsorption tower 304 and the second molecular sieve adsorption tower 305 are alternately opened and closed by the third control valve 16.

[0060] Based on the difference in the diameters of nitrogen and oxygen molecules, the selective adsorption of nitrogen by molecular sieves is utilized. Through the change of pressure, the molecular sieve adsorption tower is controlled to adsorb and desorb nitrogen. The double-tower structure is used to ensure that oxygen can be continuously produced.

[0061] Specifically, under the control of the third control valve 16, air alternately enters the first molecular sieve adsorption tower 304 and the second molecular sieve adsorption tower 305 of the oxygen concentrator 3. This allows the first molecular sieve adsorption tower 304 and the second molecular sieve adsorption tower 305 to alternately perform adsorption (nitrogen is adsorbed and oxygen passes through the adsorption tower) and desorption (release of the adsorbed nitrogen to prepare for the next round of adsorption), ensuring a continuous supply of oxygen and nitrogen. The oxygen enriched by the first molecular sieve adsorption tower 304 and the second molecular sieve adsorption tower 305 enters the oxygen tank 306 for storage or to supply oxygen to the passenger compartment. The nitrogen released during the desorption process enters the nitrogen storage tank for storage. Based on real-time demand, the nitrogen in the nitrogen storage tank can be used to inflate the tires 7.

[0062] Furthermore, the third control valve 16 has a fourth valve port, a fifth valve port, a sixth valve port, and a seventh valve port. The fourth valve port is connected to the air storage tank 1, the fifth valve port is connected to the first molecular sieve adsorption tower 304, the sixth valve port is connected to the second molecular sieve adsorption tower 305, and the seventh valve port is connected to the exhaust gas exhaust path 301. The fourth valve port is connected to the fifth valve port and the sixth valve port is connected to the seventh valve port to allow air to enter the first molecular sieve adsorption tower 304 and nitrogen to be discharged from the second molecular sieve adsorption tower 305; the fourth valve port is connected to the sixth valve port and the fifth valve port is connected to the seventh valve port to allow air to enter the second molecular sieve adsorption tower 305 and nitrogen to be discharged from the first molecular sieve adsorption tower 304.

[0063] Specifically, see Figure 3 As shown, when the fourth valve port is connected to the fifth valve port, and the sixth valve port is connected to the seventh valve port, air enters the first molecular sieve adsorption tower 304, where nitrogen is adsorbed. A portion of the oxygen passes through the first molecular sieve adsorption tower 304 and enters the oxygen tank 306, while another portion of the oxygen enters the second molecular sieve adsorption tower 305 to release the adsorbed nitrogen and other gases, thereby allowing the nitrogen to enter the waste gas discharge path 301. Similarly, when the fourth valve port is connected to the sixth valve port, and the fifth valve port is connected to the seventh valve port, air enters the first molecular sieve adsorption tower 304, where nitrogen is adsorbed. A portion of the oxygen passes through the second molecular sieve adsorption tower 305 and enters the oxygen tank 306, while another portion of the oxygen enters the first molecular sieve adsorption tower 304 to desorb, thereby allowing the nitrogen to enter the waste gas discharge path 301.

[0064] Furthermore, the oxygen concentrator 3 further includes: a sixth sensor 17 for detecting the pressure in the oxygen tank 306 , and the sixth sensor 17 is electrically connected to the controller 4 .

[0065] With this configuration, when the air pressure in oxygen tank 306 is insufficient, controller 4 turns on oxygen concentrator 3, allowing air to enter oxygen tank 306 to replenish the gas. Once sixth sensor 17 detects sufficient air pressure in oxygen tank 306, controller 4 automatically turns off oxygen concentrator 3. This ensures a sufficient supply of oxygen when needed within the passenger compartment.

[0066] Furthermore, the vehicle-mounted oxygen production system further includes: a pressure reducing valve 18 , which is connected between the air storage tank 1 and the oxygen generator 3 .

[0067] With this arrangement, when a passenger activates the oxygen generator function, the pressure reducing valve 18 opens, allowing the decompressed air in the air storage tank 1 to flow smoothly into the oxygen generator 3. When the oxygen generator 3 is operating, the oxygen in the air is used to supply the cockpit, while the nitrogen and other gases in the air are stored in the nitrogen storage tank as a supplementary air source for the tire pressure system.

[0068] Furthermore, the on-board oxygen production system also includes: a seat air pump system, the seat air pump system includes a seat airbag 19 and a second detection device 20, the seat airbag 19 is connected to the exhaust gas exhaust path 301, the second detection device 20 is used to detect the pressure of the seat airbag 19, and is electrically connected to the controller 4, and the controller 4 is configured to control the inflation and deflation of the seat airbag 19 according to the received pressure of the seat airbag 19.

[0069] With this arrangement, the exhaust gas generated by the oxygen generator 3 can not only be used as a supplementary air source for the tire pressure system, but also as a supplementary air bag for the seat air bag 19 . The controller 4 can adjust the inflation and deflation of the seat air bag 19 according to the pressure of the seat air bag 19 .

[0070] In some embodiments, the seat airbag 19 includes a seat cushion airbag 22 and a massage airbag 21. The massage airbag 21 expands and contracts to provide a massage effect on the passenger, while the seat cushion airbag 22 expands and contracts to adjust the seat height. Furthermore, the second detection device 20 includes a seventh sensor and an eighth sensor. The seventh sensor is used to detect the pressure of the seat cushion airbag 22, and the eighth sensor is used to detect the pressure of the massage airbag 21, thereby enabling the controller 4 to adjust the pressure of the massage airbag 21 and the seat cushion airbag 22.

[0071] Furthermore, the vehicle-mounted oxygen production system further includes: a control panel, which is electrically connected to the controller 4 .

[0072] A vehicle according to an embodiment of the second aspect of the present invention includes an on-board oxygen production system.

[0073] Apply the vehicle-mounted oxygen generator system to the vehicle. The specific operations can be referred to as follows:

[0074] On the human-computer interaction interface of the control panel, the driver and passengers can select a preset working condition to change the tire pressure of tire 7 to a range that is consistent with the working condition. During driving, the controller 4 can adjust the tire pressure based on the real-time data transmitted back by the first detection module 8. When the "normal" working condition option is selected, the tire pressure of tire 7 will be set to the vehicle's factory recommended value; when the "summer" working condition option is selected, the tire pressure of tire 7 will be set to the vehicle's factory recommended lower limit; when the "winter" working condition option is selected, the tire pressure of tire 7 will be set to the vehicle's factory recommended upper limit;

[0075] When the passenger turns on the oxygen production function on the control panel, the control command is sent to the controller 4, and the controller 4 makes the following instructions: First, the air compressor 14 starts working. After the outside air is purified by the air filter, it is compressed by the air compressor 14 and enters the exhaust radiator. After the air temperature is reduced, it enters the air storage tank 1. Second, the controller 4 controls the opening and closing cycle of the third control valve 16. After the air enters the molecular sieve filter device 303, the nitrogen in the air is adsorbed in the first molecular sieve adsorption tower 304 and the second molecular sieve adsorption tower 305, thereby obtaining high-purity oxygen. The oxygen will enter the oxygen tank 306, and the adsorbed nitrogen will enter the exhaust tank 302 during the desorption process. Third, at this time, the third sensor 12 detects that the air pressure in the exhaust tank 302 is sufficient, and the controller 4 will open the exhaust port of the second control valve 9 to discharge excess nitrogen and other gases out of the vehicle.

[0076] When the passenger turns on the seat massage function or raises the seat height on the control panel, the control command is sent to the controller 4. If it is detected that the air pressure in the seat airbag 19 is sufficient, the controller 4 will directly activate the corresponding function of the seat. If the air pressure in the seat airbag 19 is insufficient, the controller 4 will open the second control valve 9 to allow the nitrogen in the exhaust gas tank 302 to enter the seat airbag 19 to replenish the gas.

[0077] When the massage airbag 21 or the cushion airbag 22 in the seat airbag 19 is damaged and leaks, the second detection module will detect insufficient air pressure, and the controller 4 will automatically start the air compressor 14 and the oxygen generator 3, and continue to input nitrogen into the massage airbag 21. At this time, the function of the seat can still operate normally, ensuring the comfort of passengers on the way to repair.

[0078] When the first detection module 8 detects that the tire pressure of the tire 7 is lower than the tire pressure range of the current working conditions, the controller 4 will open the second control valve 9 to allow the nitrogen in the exhaust gas tank 302 to enter the pipeline, and then the nitrogen enters the automobile hub cover 11 and the wheel hub through the first pipeline and the drive shaft 10, and is then connected to the inner tube of the tire 7 through the second management, opening the first control valve 6 of the front and rear tires 7, and the tire 7 is inflated; when it is detected that the tire pressure of the tire 7 has reached the preset range value, the second control valve 9 and the first control valve 6 are closed, completing the tire 7 inflation process.

[0079] When the first detection module 8 detects that the tire pressure of the tire 7 is higher than the tire pressure range of the current working conditions, the tire 7 should be deflated, and the controller 4 makes the following instructions: first, the first control valve 6 and the second control valve 9 of the front and rear tires 7 are opened, and the deflation process begins; second, the gas in the tire 7 flows to the second control valve 9 through the second pipeline, and then is discharged outside the vehicle through the exhaust port on the second control valve 9; third, when it is detected that the tire pressure of the tire 7 has reached the preset range, the second control valve 9 and the first control valve 6 are closed, completing the tire 7 deflation process.

[0080] When the vehicle body needs to be raised, the controller 4 opens the passage between the air storage tank 1 and the air spring 2, allowing air to enter the air spring 2. After the air spring 2 is inflated, its volume increases, thereby raising the vehicle body;

[0081] When the vehicle body height needs to be lowered, the controller 4 will open the exhaust port on the air spring 2, and rely on the vehicle body weight to discharge the gas in the air spring 2 out of the vehicle. The volume of the air spring 2 is reduced, thereby lowering the vehicle body height.

[0082] When the air pressure in air storage tank 1 is insufficient, controller 4 will issue the following instructions: air compressor 14 will start operating. After the outside air is purified by the air filter, it is compressed by air compressor 14 and enters the exhaust radiator. After the air temperature drops, it enters air storage tank 1. When the air pressure in air storage tank 1 is sufficient, controller 4 will automatically shut down air compressor 14. If the air pressure in exhaust tank 302 is also insufficient at this time, controller 4 will issue the following instructions: controller 4 controls the opening and closing cycle of third control valve 16. After the air enters molecular sieve filter device 303, the oxygen in the air enters oxygen tank 306, and nitrogen enters exhaust tank 302 during the desorption process. When the air pressure in both air storage tank 1 and exhaust tank 302 is sufficient, controller 4 will automatically shut down air compressor 14.

[0083] In summary, by sharing an air source with the seat air pump system, tire pressure system, and air suspension system, the oxygen concentrator 3 allows the controller 4 to open and close the relevant control valves according to program settings, completing the processes of filling the seat airbag 19, inflating and deflating the tire 7, and inflating and deflating the air spring 2. Furthermore, the controller 4 monitors the temperature and pressure inside the tire in real time, adjusting the second control valve 9 to adjust the inflation and deflation process. The tire temperature and pressure data are simultaneously displayed on the control panel. This not only effectively utilizes the exhaust gas from the oxygen concentrator 3, but also integrates multiple air intake sources into a common air supply system, significantly reducing the number of components and space usage, facilitating vehicle layout.
