Abstract
Description
Technical Field
[0001] The present application relates to the technical field of vehicles, and particularly to an in-vehicle oxygen generation system and a vehicle. Background Art
[0002] With the rapid development of the automotive industry and the improvement of people's living standards, cars are no longer just means of transportation, but have gradually evolved into mobile spaces integrating multiple functions such as travel, leisure, and medical care.
[0003] In scenarios such as plateau tourism, harsh environments, and emergency medical rescue, the demand for in-vehicle oxygen increases significantly. Especially for passengers or drivers who need assisted breathing, an in-vehicle oxygen generation system is particularly important.
[0004] Most of the existing in-vehicle oxygen generation systems use in-vehicle oxygen generators to generate oxygen. They adsorb nitrogen through molecular sieves to collect oxygen and supply the oxygen to the driver and passengers to meet the oxygen demand during driving. However, such in-vehicle oxygen generation systems have a relatively single use scenario and cannot meet the oxygen demand in various situations. Utility Model Content
[0005] The present application provides an in-vehicle oxygen generation system and a vehicle to solve the problem that the existing in-vehicle oxygen generation system has a single use scenario and cannot meet special needs.
[0006] To achieve the above object, the present application adopts the following technical solutions:
[0007] In a first aspect, the present application provides an in-vehicle oxygen generation system, including: a molecular sieve oxygen generation component including a first oxygen outlet; an electrolytic oxygen generation component including a second oxygen outlet; a first multi-way valve including: a first valve port, a second valve port communicating with the first oxygen outlet, and a third valve port communicating with the second oxygen outlet; and an oxygen delivery component communicating with the first valve port.
[0008] The first valve port of the first multi-way valve can communicate with the second valve port or the third valve port. When the first valve port communicates with the second valve port, the molecular sieve oxygen generation component supplies oxygen to the oxygen delivery component. When the first valve port communicates with the third valve port, the electrolytic oxygen generation component supplies oxygen to the oxygen delivery component. In this way, when the vehicle is in a general environment, the molecular sieve oxygen generation device is started to supply oxygen to the oxygen delivery component. When in a harsh environment, the electrolytic oxygen generation device is started to supply oxygen to the oxygen delivery component, thus solving the problem of the single use scenario of the in-vehicle oxygen generation system.
[0009] In some embodiments of the present application, the in-vehicle oxygen generation system may further include a first gas storage tank, and the first multi-way valve may further include a fourth valve port communicating with the first gas storage tank.
[0010] In this way, the oxygen produced by the molecular sieve oxygen production component or the electrolytic oxygen production component can be controlled by the first multi-way valve to enter the first gas storage tank for storage and standby to meet the oxygen demand in emergency situations.
[0011] In some embodiments of the present application, the vehicle-mounted oxygen production system may further include a first oxygen concentration detection device, which is connected between the first oxygen outlet and the second valve port. The first multi-way valve may further include a fifth valve port, which is connected to the external air.
[0012] In this way, when the molecular sieve oxygen production component produces oxygen, the first oxygen concentration detection device can detect the produced oxygen concentration, and by controlling the opening and closing of the fifth valve, mix external air into the produced oxygen, thereby outputting oxygen-enriched air with different oxygen concentrations to the oxygen supply component, thereby meeting the different oxygen inhalation needs of the driver and passengers.
[0013] In some embodiments of the present application, the vehicle-mounted oxygen production system may further include a chemical oxygen production component, wherein the chemical oxygen production component includes a third oxygen outlet, and the third oxygen outlet is connected to the oxygen supply component.
[0014] In this way, when the power supply of the entire vehicle is tight and the oxygen production system cannot be powered, the chemical oxygen production component can be activated to produce oxygen to meet the oxygen needs of the driver and passengers, enriching the use scenarios of the vehicle-mounted oxygen production system.
[0015] In some embodiments of the present application, the chemical oxygen production component may include a storage chamber, a reaction chamber and a valve. The storage chamber and the reaction chamber are arranged at intervals, and the reaction chamber is arranged at the bottom of the storage chamber. A connecting channel is arranged between the storage chamber and the reaction chamber, and a valve is arranged at the connecting channel. The chemical oxygen production component may also include an air storage chamber and a filter device, the air storage chamber is arranged between the reaction chamber and the third oxygen outlet, and the filter device is arranged between the reaction chamber and the air storage chamber.
[0016] In this way, the storage chamber is used to store chemical oxygen-producing materials, and the valve is used to control whether the storage chamber is connected to the reaction chamber. When the valve is opened, the chemical oxygen-producing materials in the storage chamber fall into the reaction chamber under the action of gravity and react in the reaction chamber to generate oxygen. The oxygen is transported to the oxygen supply component through the gas storage chamber and the third oxygen outlet.
[0017] However, when oxygen enters the gas storage chamber, it may carry impurity gases and reactant powders that have not reacted completely. The filtering device is arranged between the reaction chamber and the gas storage chamber. In this way, when oxygen flows from the reaction chamber to the gas storage chamber, the impurity gases and reactant powders are filtered out by the filtering device. At the same time, the oxygen can also be cooled and buffered in the filtering device to ensure that the gas delivered to the oxygen supply component is safe and reliable.
[0018] In some embodiments of the present application, the chemical oxygen generation material may include sodium chlorate and iron, and the chemical oxygen generation assembly may further include an ignition device, at least a part of which is disposed in the reaction chamber.
[0019] At least a part of the ignition device is disposed in the reaction chamber for igniting the chemical oxygen generation material in the reaction chamber. When sodium chlorate and iron are ignited, oxygen, sodium chloride, and ferrous oxide are generated. In this chemical reaction, no polluting or harmful substances are produced, and oxygen preparation is safer and more reliable.
[0020] In some embodiments of the present application, the chemical oxygen generation assembly may further include a pressure sensor, which is disposed in the air storage chamber, and the valve may be a regulating valve.
[0021] The pressure sensor is used to detect the pressure in the air storage chamber, thereby judging the oxygen content in the air storage chamber. In this way, according to the amount of oxygen in the air storage chamber, the opening degree of the regulating valve is controlled, so as to control the feeding speed of the storage chamber to the reaction chamber, and further control the oxygen preparation rate.
[0022] In some embodiments of the present application, the oxygen delivery assembly may include an oxygen mask, which is communicated with the first valve port. The oxygen delivery assembly may further include a first one-way valve, which is communicated between the oxygen mask and the first valve port.
[0023] In this way, the oxygen produced by the molecular sieve oxygen generation assembly and the electrolytic oxygen generation assembly can enter the oxygen mask through the first valve port of the first multi-way valve, so as to supply oxygen to the passengers in the vehicle. The first one-way valve is communicated between the first valve port and the oxygen mask, which can prevent the gas in the vehicle from flowing back to the vehicle-mounted oxygen generation system and polluting the produced oxygen.
[0024] In some embodiments of the present application, the oxygen mask is communicated with the third oxygen outlet.
[0025] In this way, the chemical oxygen generation assembly can directly supply oxygen to the oxygen mask without passing through the first multi-way valve, and can still supply oxygen to the passengers when there is no power supply.
[0026] In some embodiments of the present application, the electrolytic oxygen generation assembly may include an electrolytic oxygen generation device, which may include a water inlet, a water outlet, a second oxygen outlet, and a hydrogen outlet. The electrolytic oxygen generation device may further include a circulation channel, which is respectively communicated with the water inlet and the water outlet to form a water circulation loop; the electrolytic oxygen generation device may further include an oxidation device, which is communicated between the hydrogen outlet and the circulation channel for oxidizing hydrogen into water.
[0027] In this way, during the electrolysis process of the electrolytic oxygen generation device, hydrogen and oxygen are generated. The oxygen flows through the second oxygen outlet to the first multi-way valve, and the hydrogen flows through the hydrogen outlet to the oxidation device. Hydrogen is a flammable gas. The oxidation device oxidizes hydrogen into water and transports the generated water back into the circulation channel to continue participating in the water cycle, thus avoiding the danger caused by discharging hydrogen into the air environment.
[0028] In some embodiments of the present application, a receiving space is formed inside the electrolytic oxygen generation device. The electrolytic oxygen generation device may include a membrane electrode, which is disposed inside the electrolytic oxygen generation device and divides the receiving space inside the electrolytic oxygen generation device into a first receiving space and a second receiving space. Among them, the second oxygen outlet communicates with the first receiving space, and the hydrogen outlet communicates with the second receiving space.
[0029] The electrolytic oxygen generation device may further include a water passing channel. The first receiving space and the second receiving space are both provided with water passing channels, and the water inlet and the water outlet both communicate with the water passing channel. In this way, there is water in both the first receiving space and the second receiving space for circulation.
[0030] The electrolytic oxygen generation device may further include a positive electrode and a negative electrode. Among them, the positive electrode is disposed in the first receiving space, the negative electrode is disposed in the second receiving space, and at least part of the positive electrode and at least part of the negative electrode are both located in the water passing channel.
[0031] In this way, when the electrolytic oxygen generation device is powered on, the water in the water passing channel undergoes an electrolysis reaction. At the positive electrode, water molecules are oxidized to produce oxygen, hydrogen ions, and electrons. Oxygen is generated in the first receiving space and discharged through the second oxygen outlet. The hydrogen ions can pass through the membrane electrode to the second receiving space, and the electrons can reach the vicinity of the negative electrode through the water cycle. At the negative electrode, hydrogen ions combine with electrons to generate hydrogen. Hydrogen is generated in the second receiving space and discharged through the hydrogen outlet.
[0032] In some embodiments of the present application, the membrane electrode may be a solid polymer electrolyte.
[0033] The solid polymer electrolyte has the characteristics of corrosion resistance, high temperature resistance, and vibration resistance, and can ensure the stable operation of the electrolytic oxygen generation device in a harsh environment.
[0034] In some embodiments of the present application, the molecular sieve oxygen generation assembly includes a compressor, a second multi-way valve, a first molecular sieve, a second molecular sieve, and a second oxygen storage tank. The compressor includes an exhaust port and an intake port. The second multi-way valve includes a sixth valve port, a seventh valve port, an eighth valve port, and a ninth valve port. The first molecular sieve includes a first adsorption channel and a first opening and a second opening respectively communicating with the first adsorption channel. The second molecular sieve includes a second adsorption channel and a third opening and a fourth opening respectively communicating with the second adsorption channel. The second oxygen storage tank includes a first oxygen outlet. Among them, the sixth valve port communicates with the exhaust port, the seventh valve port communicates with the external air, the first opening communicates with the eighth valve port, the third opening communicates with the second opening, and the fourth opening communicates with the ninth valve port; the second oxygen storage tank communicates with both the second opening and the third opening.
[0035] The sixth valve port of the second multi-way valve can communicate with the eighth valve port, and the seventh valve port communicates with the ninth valve port. The sixth valve port of the second multi-way valve can also communicate with the ninth valve port, and the seventh valve port communicates with the eighth valve port. In this way, the two communication modes can be switched with each other, so that the molecular sieve oxygen generation assembly can continuously generate oxygen without separately flushing the molecular sieve to remove the adsorbed nitrogen thereon, improving the oxygen generation efficiency.
[0036] In some embodiments of the present application, the molecular sieve oxygen generation assembly may further include an exhaust muffler, which is connected between the seventh valve port and the external air.
[0037] In this way, when discharging nitrogen, the exhaust muffler reduces the exhaust volume and improves the driving experience of the passengers.
[0038] In some embodiments of the present application, the molecular sieve oxygen generation assembly may further include a steam separator, which is connected between the compressor and the sixth valve port.
[0039] In this way, when the vehicle is in an environment with high air humidity such as rainy days or foggy days, the steam separator can separate the water vapor in the air and improve the oxygen generation efficiency of the molecular sieve oxygen generation assembly.
[0040] In a second aspect, the present application further provides a vehicle, including the above-mentioned on-vehicle oxygen generation system. It should be noted that the technical effects brought by the implementation manners in the second aspect can refer to the technical effects brought by the corresponding implementation manners in the first aspect, which will not be elaborated here.
[0041] In some embodiments, the vehicle may further include a vehicle body. The on-vehicle oxygen generation system is connected to the vehicle body. A driving space is formed inside the vehicle body, and an air outlet communicating with the first valve port is provided on the driving space.
[0042] In this way, the oxygen generated by the molecular sieve oxygen generation assembly or the electrolytic oxygen generation assembly can be directly transported to the air outlet through the first multi-way valve, so that the oxygen is diffused in the driving space, thereby meeting the oxygen demand of the passengers.
[0043] In some embodiments, a second oxygen concentration detection device may also be provided in the vehicle driving space.
[0044] The second oxygen concentration detection device is used to detect the oxygen concentration in the driving and passenger space. If the driving and passenger in the vehicle have no oxygen demand, the first valve port is closed, the fourth valve port is opened, and the oxygen is transported to the first gas storage tank for storage.
[0045] In some embodiments, the vehicle-mounted oxygen production system may further include a first gas storage tank, and the first multi-way valve may further include a fourth valve port connected to the first gas storage tank. The first gas storage tank is detachably arranged on the vehicle body.
[0046] In this way, when the vehicle breaks down and cannot be driven outdoors on a plateau or in the wild, or the environment inside the vehicle is no longer suitable for the driver and passengers to stay, the first gas tank can also be easily removed and taken away for use.
[0047] In some embodiments, the vehicle-mounted oxygen production system may further include a booster pump connected between the first gas storage tank and the fourth valve port.
[0048] In this way, the produced oxygen can be compressed to increase the oxygen content in the first gas storage tank, so that more oxygen can be provided to the driver and passengers after the first gas storage tank is disassembled. BRIEF DESCRIPTION OF THE DRAWINGS

[0068] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
[0069] It should be noted that all the directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.
[0070] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.
[0071] The terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0072] In the description of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection.

The specific meaning needs to be understood in combination with the context.
[0073] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Exactly speaking, the use of words such as "exemplary" or "for example" is intended to present relevant concepts in a specific manner.
[0074] With the improvement of the economic level, people's lifestyles are becoming more and more diverse. As a commonly used means of transportation, cars are constantly endowed with new functions to improve people's living experience. In recent years, with the increase in the number of long-distance travelers, when facing plateau environments, extreme weather or emergencies, the oxygen demand in the car has increased significantly. Especially for the passengers and drivers who need assisted breathing, in-vehicle oxygen generation systems have become particularly important.
[0075] Existing automotive oxygen generation usually uses an in-vehicle oxygen generator to meet the oxygen needs of drivers and passengers. There is a molecular sieve inside the in-vehicle oxygen generator. By powering on the oxygen generator, external air enters the oxygen generator, and the molecular sieve in the oxygen generator adsorbs nitrogen and filters out oxygen with a higher concentration for the use of drivers and passengers. However, when facing harsh environments, such as sandstorms and heavy rain, there are a large number of impurities in the air, and the efficiency of the oxygen generator is greatly reduced, unable to meet the oxygen demand.
[0076] Based on this, the embodiments of the present application provide an in-vehicle oxygen generation system. By setting two different oxygen generation components, namely a molecular sieve oxygen generation component and an electrolytic oxygen generation component, a suitable oxygen generation method can be selected in different environments to provide for drivers and passengers, thereby solving the problem in the prior art that the in-vehicle oxygen generation system has a single usage scenario and cannot meet the oxygen demand in multiple situations.
[0077] Please refer to Figure 1 , Figure 1 FIG. 100 is one of the structural schematic diagrams of an in-vehicle oxygen generation system 100 provided by the embodiments of the present application. The in-vehicle oxygen generation system 100 may include a molecular sieve oxygen generation component 10, an electrolytic oxygen generation component 20, a first multi-way valve 30, and an oxygen delivery component 40.
[0078] Among them, the molecular sieve oxygen generation component 10 may include a first oxygen outlet 101, the electrolytic oxygen generation component 20 may include a second oxygen outlet 201, and the first multi-way valve 30 may include a first valve port 301, a second valve port 302, and a third valve port 303. The first valve port 301 is communicated with the oxygen delivery component 40, the second valve port 302 is communicated with the first oxygen outlet 101, and the third valve port 303 is communicated with the second oxygen outlet 201.
[0079] In this way, the first valve port 301 of the first multi-way valve 30 can be communicated with the second valve port 302 or the third valve port 303. When the first valve port 301 is communicated with the second valve port 302, the molecular sieve oxygen generation component 10 provides oxygen to the oxygen delivery component 40. When the first valve port 301 is communicated with the third valve port 303, the electrolytic oxygen generation component 20 provides oxygen to the oxygen delivery component 40. In this way, when in a general environment, the molecular sieve oxygen generation component 10 is started to deliver oxygen to the oxygen delivery component 40. When in a harsh environment, such as an environment with low air utilization rate like a sandstorm or heavy rain, the electrolytic oxygen generation component 20 is started to deliver oxygen to the oxygen delivery component 40, thereby solving the problem of the single usage scenario of the in-vehicle oxygen generation system 100.
[0080] Please refer to Figure 2 , Figure 2This is the second schematic structural diagram of an in-vehicle oxygen generation system 100 provided by an embodiment of the present application. In some embodiments of the present application, the in-vehicle oxygen generation system 100 may further include a first gas storage tank 50. The first multi-way valve 30 may further include a fourth valve port 304, and the fourth valve port 304 is communicated with the first gas storage tank 50.
[0081] In this way, the fourth valve port 304 can be communicated with the first valve port 301, the second valve port 302, and the third valve port 303. In this way, the oxygen produced by the molecular sieve oxygen generation assembly 10 or the electrolytic oxygen generation assembly 20 can enter the first gas storage tank 50 for storage and standby through the control of the first multi-way valve 30 to meet the oxygen demand in case of emergency.
[0082] Please refer to Figure 3 , Figure 3 This is the third schematic structural diagram of an in-vehicle oxygen generation system 100 provided by an embodiment of the present application. In some embodiments of the present application, the in-vehicle oxygen generation system 100 may further include a first oxygen concentration detection device 60. The first oxygen concentration detection device 60 is communicated between the first oxygen outlet 101 and the second valve port 302. The first multi-way valve 30 may further include a fifth valve port 305, and the fifth valve port 305 is communicated with the external air.
[0083] Optionally, the first oxygen concentration detection device 60 may be an electrochemistry oxygen detector, and the electrochemistry oxygen detector may measure the oxygen concentration by measuring the voltage generated by the current between the oxygen and the electrode. Since the electrochemistry oxygen detector has advantages such as high accuracy and fast response speed, in this way, the accuracy of detecting the oxygen concentration of the oxygen produced by the molecular sieve oxygen generation assembly 10 can be improved.
[0084] Optionally, the first oxygen concentration detection device 60 may also be an optical oxygen detector, a thermal conductivity oxygen detector, a zirconia oxygen detector, a paramagnetic oxygen detector, etc., and the present application does not limit this.
[0085] In this way, when the molecular sieve oxygen generation assembly 10 generates oxygen, the first oxygen concentration detection device 60 can detect the oxygen concentration of the generated oxygen. By controlling the opening and closing of the fifth valve port 305, the external air is mixed into the generated oxygen, so as to output oxygen-enriched air with different oxygen concentrations to the oxygen delivery assembly 40, thereby meeting the different oxygen inhalation needs of the driver and passengers.
[0086] Please refer to Figure 4 , Figure 4 This is the fourth schematic structural diagram of an in-vehicle oxygen generation system 100 provided by an embodiment of the present application. In some embodiments of the present application, the in-vehicle oxygen generation system 100 may further include a chemical oxygen generation assembly 70. The chemical oxygen generation assembly 70 includes a third oxygen outlet 701, and the third oxygen outlet 701 is communicated with the oxygen delivery assembly 40.
[0087] The chemical oxygen generation component 70 can operate normally to generate oxygen without being powered by the whole vehicle. In this way, when in deserts, gobi areas, or situations lacking supplies, where the vehicle's power supply is strained and unable to power the oxygen generation system, the chemical oxygen generation component 70 can be activated to generate oxygen, meeting the oxygen needs of the passengers and enriching the usage scenarios of the vehicle-mounted oxygen generation system 100.
[0088] Please refer to Figure 5 , Figure 5 FIG. Figure 5 is a schematic structural diagram of a chemical oxygen generation component 70 provided by an embodiment of the present application. In some embodiments of the present application, the chemical oxygen generation component 70 may include a storage chamber 71, a reaction chamber 72, and a valve 73. The storage chamber 71 and the reaction chamber 72 are spaced apart, and the reaction chamber 72 is disposed at the bottom of the storage chamber 71. A communication channel is provided between the storage chamber 71 and the reaction chamber 72, and a valve 73 is provided at the communication channel.
[0089] In this way, the storage chamber 71 is used to store chemical oxygen generation materials, and the valve 73 is used to control whether the storage chamber 71 and the reaction chamber 72 are connected. When the valve 73 is opened, the chemical oxygen generation materials in the storage chamber 71 fall into the reaction chamber 72 under the action of gravity and react in the reaction chamber 72 to generate oxygen.
[0090] It can be understood that the reaction of the chemical oxygen generation materials in the reaction chamber 72 may not be complete, resulting in the generation of impurity gases (such as chlorine gas), and the generated gas may carry reactant powders.
[0091] In some embodiments of the present application, the chemical oxygen generation component 70 may further include a gas storage chamber 74 and a filtering device 75. The gas storage chamber 74 is disposed between the reaction chamber 72 and the third oxygen outlet 701, and the filtering device 75 is disposed between the reaction chamber 72 and the gas storage chamber 74.
[0092] Since the filtering device 75 is disposed between the reaction chamber 72 and the gas storage chamber 74, the filtering device 75 can filter the gas flowing from the reaction chamber 72 into the gas storage chamber 74. In this way, the impurity gases and reactant powders mixed in the oxygen are filtered out by the filtering device 75. At the same time, the oxygen can also be cooled and buffered in the filtering device 75. The filtered gas enters the gas storage chamber 74 and is transported to the oxygen delivery component 40 through the third oxygen outlet 701, ensuring the safety and reliability of the gas transported to the oxygen delivery component 40.
[0093] In some embodiments, the chemical oxygen generation materials may include sodium chlorate and iron, and the chemical oxygen generation component 70 may further include an ignition device 76, at least a part of which is disposed inside the reaction chamber 72.
[0094] Among them, the ignition device 76 may include a backup battery 761, a relay 762, and an activation device 763. The relay 762 is connected between the backup battery 761 and the activation device 763 and is used to supply the electrical energy stored in the backup battery 761 to the activation device 763. The activation device 763 can convert electrical energy into heat energy to ignite the chemical oxygen generation material in the reaction chamber 72. At least part of the ignition device is disposed in the reaction chamber 72 for igniting the chemical oxygen generation material in the reaction chamber 72. The at least part may include the activation device 763 or may only include the fire outlet. The present application does not make further limitations thereon.
[0095] Since the chemical oxygen generation material includes sodium chlorate and iron, oxygen, sodium chloride, and ferrous oxide can be generated after the ignition reaction of sodium chlorate and iron. In this chemical reaction, no pollutants or harmful substances are produced, and oxygen preparation is safer and more reliable.
[0096] In some embodiments of the present application, the chemical oxygen generation assembly 70 may further include a pressure sensor 77. The pressure sensor 77 is disposed in the air storage chamber 74 and is used to detect the pressure in the air storage chamber 74. The valve 73 may be a regulating valve 73A.
[0097] The regulating valve 73A can control the opening degree of the communication between the storage chamber 71 and the reaction chamber 72 by controlling the cross-sectional area of the opened valve, so that by adjusting the opening degree of the regulating valve 73A, the feeding amount of the storage chamber 71 to the reaction chamber 72 can be controlled, thereby controlling the oxygen generation rate of the chemical oxygen generation assembly 70.
[0098] The pressure sensor 77 is used to detect the pressure in the air storage chamber 74. When there is more gas in the air storage chamber 74 and the pressure is greater than or equal to the first preset pressure value, the opening degree of the regulating valve 73A is reduced, so that the feeding amount of the storage chamber 71 to the reaction chamber 72 is reduced, thereby slowing down the oxygen generation rate; when there is less gas in the air storage chamber 74 and the pressure is less than the second preset pressure value, the opening degree of the regulating valve 73A is increased, so that the feeding amount is increased, thereby accelerating the oxygen generation rate.
[0099] Please refer to Figure 6 , Figure 6 FIG. 5 is a schematic structural diagram of a vehicle-mounted oxygen generation system 100 provided by an embodiment of the present application. In some embodiments, the oxygen delivery assembly 40 may include an oxygen mask 41. The oxygen mask 41 is communicated with the first valve port 301. The oxygen delivery assembly 40 may further include a first one-way valve 42, which is communicated between the oxygen mask 41 and the first valve port 301.
[0100] In this way, the oxygen produced by the molecular sieve oxygen generation component 10 and the electrolytic oxygen generation component 20 can enter the oxygen mask 41 through the first valve port 301 of the first multi-way valve 30, so as to supply oxygen to the driver and passengers in the vehicle. The first one-way valve 42 is connected between the first valve port 301 and the oxygen mask 41. When the gas flows from the first valve port 301 to the oxygen mask 41, the first one-way valve 42 opens. When the gas flows from the oxygen mask 41 to the first valve port 301, the first one-way valve 42 closes. In this way, the gas in the vehicle can be prevented from flowing back to the vehicle-mounted oxygen generation system 100 and polluting the produced oxygen.
[0101] In some embodiments, the oxygen mask 41 is communicated with the third oxygen outlet 701. In this way, the oxygen produced by the chemical oxygen generation component 70 can directly flow to the oxygen mask 41. When the vehicle cannot supply power to the vehicle-mounted oxygen generation system 100, the first multi-way valve 30 may not operate normally. The chemical oxygen generation component 70 directly supplies oxygen to the oxygen mask 41, so that oxygen can still be supplied to the driver and passengers when there is no power supply.
[0102] In some embodiments, with continued reference to Figure 5 , the oxygen mask 41 may further include an air outlet valve 411, which is arranged on the oxygen mask 41 and is used to control whether to supply gas to the oxygen mask 41.
[0103] In some embodiments, the chemical oxygen generation component 70 may further include an air delivery pipe 78, which is connected between the gas storage chamber 74 and the third oxygen outlet 701 and is used to deliver the oxygen in the gas storage chamber 74 to the oxygen mask 41.
[0104] In some embodiments, the chemical oxygen generation component 70 may further include a flow regulating valve 79, which is arranged on the air delivery pipe 78 and is used to control the rate of the gas output from the gas storage chamber 74 to the oxygen mask 41. In this way, the driver and passengers can adjust the gas delivery flow according to their actual oxygen requirements.
[0105] It can be understood that the oxygen produced in the reaction chamber 72 is stored in the gas storage chamber 74 and then transported to the oxygen mask 41 through the gas pipeline 78. When the oxygen production rate is greater than the output rate, the gas accumulates in the gas storage chamber 74, causing the pressure in the gas storage chamber 74 to increase. When it reaches the first preset pressure value, that is, when it is greater than or equal to the first preset pressure value, the pressure sensor 77 can send a first signal to the regulating valve 73A. After receiving the first signal, the regulating valve 73A controls the reduction of its own opening degree, reducing the feeding amount from the storage chamber 71 to the reaction chamber 72, thereby slowing down the oxygen production rate. When the oxygen production rate is less than the output rate, the gas in the gas storage chamber 74 is less, causing the pressure in the gas storage chamber 74 to decrease. When it is less than the second preset pressure value, the pressure sensor 77 can send a second signal to the regulating valve 73A. After receiving the second signal, the regulating valve 73A controls the increase of its own opening degree, increasing the feeding amount from the storage chamber 71 to the reaction chamber 72, thereby accelerating the oxygen production rate.
[0106] In this way, it can not only meet the oxygen demand of the driver and passengers, but also save chemical oxygen generation materials and avoid waste.
[0107] When the oxygen deficiency condition of the driver and passengers is relieved and oxygen generation is not required, the flow regulating valve 79 is closed, or the flow rate of the flow regulating valve 79 is adjusted to 0, the valve 73 is completely closed or the opening degree of the regulating valve 73A is 0, and the storage chamber 71 no longer feeds the reaction chamber 72. When the chemical oxygen generation raw materials in the reaction chamber 72 are exhausted, the reaction stops and no more oxygen is produced.
[0108] In this way, the remaining chemical oxygen generation materials in the storage chamber 71 can be used again when oxygen is needed next time, solving the problem in the prior art that the chemical oxygen generation materials react once and cannot be aborted, and improving the service life of the chemical oxygen generation component 70.
[0109] In some embodiments, the chemical oxygen generation component 70 may further include a mass sensor 710, which can be disposed at the bottom of the storage chamber 71 for detecting the mass of the chemical oxygen generation materials in the storage chamber 71.
[0110] The chemical oxygen generation component 70 may further include a reminder device for reminding the driver and passengers to replenish the chemical oxygen generation materials in the storage chamber 71 when the mass sensor 710 detects that the mass of the chemical oxygen generation materials in the storage chamber 71 is less than a preset value.
[0111] In an alternative embodiment, the reminder device may be a display screen, and the remaining amount of the chemical oxygen generation materials in the storage chamber 71 can be displayed on the display screen. When the mass sensor 710 detects that the mass of the chemical oxygen generation materials in the storage chamber 71 is less than a preset value, the mass sensor 710 sends a signal to the display screen, and when the display screen receives the signal, it displays a preset picture to remind the driver and passengers to replenish the chemical oxygen generation materials in the storage chamber 71.
[0112] In another alternative embodiment, the reminder device may be a sound device. When the mass sensor 710 detects that the mass of the chemical oxygen generation material in the storage chamber 71 is less than a preset value, the mass sensor 710 sends a signal to the sound device, and the sound device broadcasts a preset prompt message to remind the driver and passenger to replenish the chemical oxygen generation material in the storage chamber 71.
[0113] In this way, when the remaining amount of the chemical oxygen generation material is insufficient, a reminder can be sent to the driver and passenger, and the driver and passenger replenish the chemical oxygen generation material in the storage chamber 71, which is convenient to ensure sufficient materials for the next use.
[0114] It can be understood that when opening the storage chamber 71 to replenish the chemical oxygen generation material, the driver and passenger can simultaneously open the reaction chamber 72 to clean the reaction products therein.
[0115] Please refer to Figure 7 , Figure 7 FIG. 15 is one of the schematic structural diagrams of an electrolytic oxygen generation device 21 provided by an embodiment of the present application. In some embodiments of the present application, in combination with Figure 6 , the electrolytic oxygen generation assembly 20 may include an electrolytic oxygen generation device 21. The electrolytic oxygen generation device 21 may include a water inlet 211, a water outlet 212, a second oxygen outlet 201, and a hydrogen outlet 202. The electrolytic oxygen generation device 21 may further include a circulation channel 213. The circulation channel 213 is respectively communicated with the water inlet 211 and the water outlet 212 to form a water circulation loop.
[0116] The electrolytic oxygen generation device 21 may further include an oxidation device 214. The oxidation device 214 is communicated between the hydrogen outlet 202 and the circulation channel 213, and is used to oxidize the hydrogen generated during the electrolysis process of the electrolytic oxygen generation device 21 into water, and convey the oxidized water back to the circulation channel 213 to continue to participate in the water circulation. In this way, hydrogen is a flammable gas. Oxidizing hydrogen into water can avoid the danger caused by discharging hydrogen into the air environment.
[0117] Please refer to Figure 8 , Figure 8 FIG. 17 is another schematic structural diagram of an electrolytic oxygen generation device 21 provided by an embodiment of the present application. In some embodiments of the present application, an accommodation space 22 is formed in the electrolytic oxygen generation device 21. The electrolytic oxygen generation device 21 may include a membrane electrode 23. The membrane electrode 23 is disposed in the electrolytic oxygen generation device 21 and divides the accommodation space in the electrolytic oxygen generation device 21 into a first accommodation space 221 and a second accommodation space 222. Among them, the second oxygen outlet 201 is communicated with the first accommodation space 221, and the hydrogen outlet 202 is communicated with the second accommodation space 222.
[0118] The electrolytic oxygen generation device 21 may further include a water passage 24. The water passage 24 is provided in both the first accommodation space 221 and the second accommodation space 222, and both the water inlet 211 and the water outlet 212 are communicated with the water passage 24. Thus, water can circulate in both the first accommodation space 221 and the second accommodation space 222.
[0119] The electrolytic oxygen generation device 21 may further include a positive electrode 25 and a negative electrode 26. The positive electrode 25 is disposed in the first accommodation space 221, and the negative electrode 26 is disposed in the second accommodation space 222. At least part of the positive electrode 25 and at least part of the negative electrode 26 are both located in the water passage 24.
[0120] When the electrolytic oxygen generation device 21 is powered on, the water in the water passage 24 undergoes an electrolysis reaction. At the positive electrode 25, water molecules are oxidized to produce oxygen, hydrogen ions and electrons. Oxygen is generated in the first accommodation space 221 and discharged through the second oxygen outlet 201. Hydrogen ions can pass through the membrane electrode to the second accommodation space 222, and electrons can reach the vicinity of the negative electrode 26 through the water circulation. At the negative electrode 26, hydrogen ions combine with electrons to generate hydrogen. Hydrogen is generated in the second accommodation space 222 and discharged through the hydrogen outlet 202.
[0121] In some embodiments, the membrane electrode 23 may be a solid polymer electrolyte (SPE).
[0122] The SPE has the characteristics of corrosion resistance, high temperature resistance and vibration resistance, which can ensure the stable operation of the vehicle-mounted oxygen supply system 100 in harsh environments. In addition, the SPE is a chain polymer with stable performance. During the electrolysis process, the generated hydrogen and oxygen have high purity and are easy to separate. There is no corrosive liquid during electrolysis, and no pollutants are generated. At the same time, the electrolytic oxygen generation device 21 using the SPE has high electrolysis efficiency, low energy consumption, does not need to be frequently repaired and replaced, and has a long service life.
[0123] Please refer to Figure 9 , Figure 9FIG. 0 is a third schematic structural diagram of an electrolytic oxygen generation device 21 provided by an embodiment of the present application. In some embodiments, the membrane electrode 23 uses SPE to produce oxygen. The electrolytic oxygen generation device 21 may further include a current collector plate 27, an end plate 28, and a sealing ring. The water passing channel 24 is arranged on the current collector plate 27, and the current collector plate 27 is attached to the positive electrode 25 and the negative electrode 26, and the water passing channel 24 on the current collector plate 27 may be in contact with the positive electrode 25 or the negative electrode 26. The end plate 28 is arranged on the side of the current collector plate 27 away from the membrane electrode 23 and is attached to the current collector plate 27. The end plate 28 is provided with a water inlet 211 and a water outlet 212. The end plate 28 is used to fix the current collector plate 27, the positive electrode 25, the negative electrode 26, and the membrane electrode 23 to make them in close contact to form an integral body. The sealing ring is arranged between the contact surfaces of the end plate 28, the current collector plate 27, the positive electrode 25, the membrane electrode 23, and the negative electrode 26 to make the connection between each component tight and avoid water leakage and air leakage.
[0124] Thus, compared with the existing liquid electrolysis device with the same oxygen production, the electrolytic oxygen generation device 21 is lighter in weight, only 1 / 3 of the weight of the liquid electrolysis device, and under the condition of outputting the same gas flow rate and the same oxygen concentration, it is more compact in volume and occupies less space.
[0125] Please refer to Figure 10 , Figure 10 FIG. 10 is a schematic structural diagram of an electrolytic oxygen generation assembly 20 provided by an embodiment of the present application; in some embodiments of the present application, the electrolytic oxygen generation assembly 20 may include a plurality of electrolytic oxygen generation devices 21, and the plurality of electrolytic oxygen generation devices 21 are arranged in parallel. Exemplarily, the plurality of electrolytic oxygen generation devices 21 may be: 2, 3, 5, 7, 8, 10, or 11, etc. The present application does not limit this.
[0126] The electrolytic oxygen generation assembly 20 may further include switches 29. The switches 29 may be provided in plurality and are arranged in one-to-one correspondence with the plurality of electrolytic oxygen generation devices 21 for controlling the on / off of each electrolytic oxygen generation device 21.
[0127] Please refer to Figure 11 , Figure 11 FIG. 20 is a first schematic structural diagram of a molecular sieve oxygen generation assembly 10 provided by an embodiment of the present application. In some embodiments of the present application, the molecular sieve oxygen generation assembly 10 may include a compressor 11, a second multi-way valve 12, a first molecular sieve 13, a second molecular sieve 14, and a second gas storage tank 15. Among them, the compressor 11 may include an exhaust port 111 and an air inlet 112; the second multi-way valve 12 may include a sixth valve port 121, a seventh valve port 122, an eighth valve port 123, and a ninth valve port 124. The sixth valve port 121 is communicated with the exhaust port 111, and the seventh valve port 122 is communicated with the external air.
[0128] Among them, the first molecular sieve 13 may include a first adsorption channel, and a first opening 131 and a second opening 132 respectively communicating with the first adsorption channel. Among them, the first opening 131 communicates with the eighth valve port 123; the second molecular sieve 14 may include a second adsorption channel, and a third opening 141 and a fourth opening 142 respectively communicating with the second adsorption channel. Among them, the third opening 141 communicates with the second opening 132, and the fourth opening 142 communicates with the ninth valve port 124; the second gas storage tank 15 is communicated with both the second opening 132 and the third opening 141.
[0129] In addition, the sixth valve port 121 of the second multi-way valve 12 may communicate with the eighth valve port 123, and the sixth valve port 121 may also communicate with the ninth valve port 124. By changing the communication mode of the valve ports of the second multi-way valve 12, it is possible to control the oxygen production of the first molecular sieve 13 or the second molecular sieve 14.
[0130] In a possible implementation manner, the sixth valve port 121 of the second multi-way valve 12 may communicate with the eighth valve port 123, and the seventh valve port 122 communicates with the ninth valve port 124. In this way, the air inlet 112 of the compressor 11 can communicate with the external air, the exhaust port 111 communicates with the sixth valve port 121, the sixth valve port 121 communicates with the eighth valve port 123, and the eighth valve port 123 communicates with the first opening 131.
[0131] Thus, the compressor 11 inhales the external air through the air inlet 112 and compresses it into high-pressure gas. The high-pressure gas is discharged from the exhaust port 111, enters the first molecular sieve 13 through the sixth valve port 121 and the eighth valve port 123 of the second multi-way valve 12, and the high-pressure gas enters the first adsorption channel from the first opening 131. The nitrogen therein is adsorbed in the first adsorption channel, and the oxygen is discharged from the second opening 132. The second opening 132 communicates with both the third opening 141 and the second gas storage tank 15, so that the oxygen can enter the second gas storage tank 15 and the second molecular sieve 14.
[0132] The second gas storage tank 15 includes a first oxygen outlet 101, and the first oxygen outlet 101 communicates with the second valve port 302. The second gas storage tank 15 is used to deliver oxygen to the oxygen delivery assembly 40 and can play a role in stabilizing the pressure.
[0133] It can be understood that the diameter of the communication channel between the second opening 132 and the second gas storage tank 15 is larger than the diameter of the communication channel between the second opening 132 and the third opening 141. In this way, when the oxygen enters the second gas storage tank 15 and the second molecular sieve 14, most of the oxygen enters the second gas storage tank 15, and a small part of the oxygen enters the second molecular sieve 14.
[0134] In a possible implementation, the sixth valve port 121 of the second multi-way valve 12 can communicate with the ninth valve port 124, and the seventh valve port 122 communicates with the eighth valve port 123. In this way, the air inlet 112 of the compressor 11 can communicate with the external air, the air outlet 111 communicates with the sixth valve port 121, the sixth valve port 121 communicates with the ninth valve port 124, and the ninth valve port 124 communicates with the fourth opening 142.
[0135] In this way, the compressor 11 inhales external air through the air inlet 112 and compresses it into high-pressure gas. The high-pressure gas is discharged from the air outlet 111, enters the second molecular sieve 14 through the sixth valve port 121 and the ninth valve port 124 of the second multi-way valve 12, the high-pressure gas enters the second adsorption channel from the fourth opening 142, and the nitrogen therein is adsorbed in the second adsorption channel, and the oxygen is discharged from the third opening 141. The third opening 141 communicates with both the second opening 132 and the second gas storage tank 15, so that oxygen can enter the second gas storage tank 15 and the first molecular sieve 13.
[0136] It can be understood that the caliber of the communication channel between the third opening 141 and the second gas storage tank 15 is larger than the caliber of the communication channel between the third opening 141 and the second opening 132. In this way, when oxygen enters the second gas storage tank 15 and the first molecular sieve 13, most of the oxygen enters the second gas storage tank 15, and a small part of the oxygen enters the first molecular sieve 13.
[0137] When the molecular sieve oxygen generation assembly 10 starts to work, the sixth valve port 121 can communicate with the eighth valve port 123, and the seventh valve port 122 is disconnected from the ninth valve port 124, so that air first enters the first molecular sieve 13 for oxygen generation. After the molecular sieve oxygen generation assembly 10 works for a preset time (for example, it can be 10 minutes, 15 minutes or 20 minutes), the seventh valve port 122 communicates with the ninth valve port 124, so that the pressure in the second molecular sieve 14 decreases, and the oxygen flowing into the second molecular sieve 14 blows out the nitrogen adsorbed on the second adsorption channel. At this time, the second multi-way valve 12 is switched to the sixth valve port 121 communicating with the ninth valve port 124, and the seventh valve port 122 is disconnected from the eighth valve port 123, so that air first enters the second molecular sieve 14 for oxygen generation. Similarly, after working for the preset time, the seventh valve port 122 communicates with the eighth valve port 123, so that the pressure in the first molecular sieve 13 decreases, and the oxygen flowing into the first molecular sieve 13 blows out the nitrogen adsorbed on the first adsorption channel. At this time, the second multi-way valve 12 is switched again to the sixth valve port 121 communicating with the eighth valve port 123, and so on in a cyclic conversion until the molecular sieve oxygen generation assembly 10 stops working.
[0138] In this way, the molecular sieve oxygen generation assembly 10 can continuously generate oxygen without separately flushing the molecular sieve to remove the adsorbed nitrogen, improving the oxygen generation efficiency.
[0139] Please refer to Figure 12 , Figure 12 FIG. Figure 12 is a second schematic structural view of a molecular sieve oxygen generation assembly 10 provided by an embodiment of the present application. In some embodiments, the molecular sieve oxygen generation assembly 10 may further include an exhaust muffler 16, and the exhaust muffler 16 is communicated between a seventh valve port 122 and external air. In this way, when discharging nitrogen, the exhaust volume can be reduced, and the driving experience of the driver and passengers can be improved.
[0140] In some embodiments, the molecular sieve oxygen generation assembly 10 may further include a moisture separator 17, and the moisture separator 17 is communicated between a compressor 11 and a sixth valve port 121. In this way, when the vehicle is in an environment with high air humidity such as rainy days or foggy days, the moisture separator 17 can separate the water vapor in the air, and improve the oxygen generation efficiency of the molecular sieve oxygen generation assembly 10.
[0141] In some embodiments, the molecular sieve oxygen generation assembly 10 may further include a filter 18, and the filter 18 is communicated between an air inlet 112 of the compressor 11 and air. In this way, the filter 18 can filter the air entering the compressor 11, remove substances such as dust and impurities therein, and is beneficial to improving the service life of the compressor 11.
[0142] In some embodiments, the molecular sieve oxygen generation assembly 10 may further include an exhaust radiator 19, and the exhaust radiator 19 is communicated between the compressor 11 and the moisture separator 17. In this way, the exhaust radiator 19 can cool the high-temperature and high-pressure gas discharged from the compressor 11, and improve the adsorption efficiency of the molecular sieve.
[0143] Please refer to Figure 13 and Figure 14 , Figure 13 FIG. Figure 13 is a first schematic structural view of a vehicle 1000 provided by an embodiment of the present application. Figure 14 FIG. Figure 14 is a second schematic structural view of a vehicle 1000 provided by an embodiment of the present application. An embodiment of the present application provides a vehicle 1000, which includes an in-vehicle oxygen generation system 100, and may further include a vehicle body. The in-vehicle oxygen generation system 100 is connected to the vehicle body, and a driving space is formed inside the vehicle body. An air outlet 43 communicated with a first valve port 301 is provided on the driving space. In this way, the oxygen generated by the molecular sieve oxygen generation assembly 10 or the electrolytic oxygen generation assembly 20 can be directly transported to the air outlet 43 through a first multi-way valve 30, so that the oxygen is diffused in the driving space, thereby meeting the oxygen demand of the driver and passengers.
[0144] It can be understood that a first one-way valve 42 is provided between the first valve port 301 and an oxygen mask 41. As shown in Figure 13 , the air outlet 43 can be communicated between the first valve port 301 and the first one-way valve 42. As shown in Figure 14As shown, it can also be connected between the first check valve 42 and the oxygen mask 41. When the air outlet 43 is connected between the first valve port 301 and the first check valve 42, in order to prevent the gas in the driving space from flowing back to the vehicle-mounted oxygen production system 100 through the air outlet 43 and contaminating the produced oxygen, a second check valve 44 can be set to be connected between the first valve port 301 and the air outlet 43.
[0145] In some embodiments of the present application, the vehicle 1000 may further include a second oxygen concentration detection device 80, which is disposed in the driving space and is used to detect the oxygen concentration in the driving space. If the vehicle occupants have no oxygen demand, the first valve port 301 is closed, the fourth valve port is opened, and the oxygen is delivered to the first gas storage tank 50 for storage.
[0146] In some embodiments of the present application, the first gas tank 50 is detachably mounted on the vehicle body. In this way, when the vehicle is broken down and cannot be driven outdoors, or the vehicle environment is no longer suitable for the driver and passengers to stay, the first gas tank 50 can also be easily removed and taken away for use.
[0147] Please refer to Figure 15 , Figure 15 The sixth structural diagram of a vehicle-mounted oxygen production system 100 provided in an embodiment of the present application, in some embodiments of the present application, the vehicle-mounted oxygen production system 100 may further include a booster pump 51, and the booster pump 51 is connected between the first gas storage tank 50 and the fourth valve port 304. In this way, the produced oxygen can be compressed to increase the oxygen content in the first gas storage tank 50, so that after the first gas storage tank 50 is disassembled, more oxygen can be provided to the driver and passengers.
[0148] Please refer to Figure 16 , Figure 16This is the third schematic diagram of the structure of a vehicle 1000 provided by an embodiment of the present application. In some embodiments of the present application, the vehicle 1000 may further include an Electronic Control Unit (ECU) and a Driver Monitoring System (DMS). The ECU is used to calculate the driving conditions of the vehicle through various sensors, so as to control multiple parameters such as engine ignition, air-fuel ratio, idle speed, and exhaust gas recirculation. When a system failure occurs, the ECU can also automatically record the fault code in the memory and adopt protective measures to read the alternative program from the inherent program to maintain the operation of the engine. The DMS is used to detect the details of the driver's head, eyes, face, and hands in real time through a vision sensor, so as to monitor the driver's behavior state. For example, fatigue driving detection, distraction detection, dangerous driving detection, infrared blocking detection, driver leaving post detection, seat belt detection, and camera occlusion detection. When the DMS monitors the abnormal state of the driver, it combines with the ECU to give an alarm to the driver, improving driving safety.
[0149] In some embodiments of the present application, the vehicle 1000 may further include seats, which are arranged inside the vehicle body and can be set in multiple numbers. The vehicle 1000 further includes a pressure sensor, which is arranged on the seat and is used to detect whether there is someone on the seat.
[0150] In this way, when the vehicle 1000 stops running and the vehicle power supply is disconnected, the in-vehicle DMS and the pressure sensor continue to work. Exemplarily, the working time is 30 minutes to 60 minutes. For example, the working time can be 30 minutes, 40 minutes, 45 minutes, 50 minutes, or 60 minutes, and is used to detect whether there are any remaining people in the vehicle. If any remaining people are detected, the DMS and the pressure sensor will send signals to the ECU, and the ECU will notify the driver. Exemplarily, it will send a reminder message about the remaining people to the driver to notify the driver. If the driver does not handle it within the reserved time, Exemplarily, the reserved time can be 20 minutes, 30 minutes, or 40 minutes, then the ECU will release the oxygen in the second air storage tank 15 into the vehicle through the air outlet 43 to delay the physical discomfort of the remaining people in the vehicle caused by insufficient oxygen.
[0151] In some embodiments of the present application, please refer to Figure 12 、 Figure 13 、 Figure 14 and Figure 16 , the on-vehicle oxygen generation system includes a pulsed solenoid valve, which is connected between the second air storage tank 15 and the air outlet 43. When the DMS and the pressure sensor detect that there are remaining people in the vehicle and the ECU controls the second air storage tank 15 to release oxygen, the oxygen is released in a pulsed form. In this way, oxygen waste can be reduced and the oxygen supply duration can be increased.
[0152] In some embodiments of the present application, the vehicle 1000 may further include a control panel for controlling various functions of the vehicle 1000.
[0153] In addition, please refer to Figure 5 , the ignition device 76 may further include a key, which is connected between the backup battery 761 and the relay 762, and can control whether the backup battery 761 supplies power to the relay 762.
[0154] The ignition device 76 can be started through the control panel, or through the ECU, or through the key.
[0155] In this way, the driver and passengers can manually control the chemical oxygen generation component 70 through the key or the control panel to start preparing oxygen. At the same time, when encountering danger, the vehicle 1000 can also automatically control the chemical oxygen generation component 70 to generate oxygen through the ECU and supply oxygen to the driver and passengers.
[0156] In some embodiments of the present application, please refer to Figure 13 , Figure 14 , Figure 15 and Figure 16 , when the second oxygen concentration detection device 80 detects that the oxygen concentration in the passenger compartment is less than or equal to the first preset threshold, or the DMS detects that the person is slightly fatigued, and the driver and passengers are in a conscious state, the ECU sends a signal to the driver and passengers for intelligent voice reminder, and a request to start the chemical oxygen generation component 70 pops up on the control panel. The person can judge whether to immediately start the chemical oxygen generation component 70 according to their own situation. When the second oxygen concentration detection device 80 detects that the oxygen concentration in the passenger compartment is less than or equal to the second preset threshold, or the DMS detects that the person is moderately fatigued, and the consciousness of the driver and passengers has been affected, the ECU forcibly starts the chemical oxygen generation component 70 and opens the oxygen mask 41 to cover the faces of the driver and passengers to provide oxygen for the driver and passengers.
[0157] Exemplarily, the first preset threshold may be 19%, 19.5%, 20% or 20.9%, and the second preset threshold may be 15%, 15.5%, 16%, 16.5% or 17%.
[0158] As described above, the above are only the specific embodiments of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application should be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
