DETAILED DESCRIPTION

[0057] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of the present application, and cannot be understood as limiting the embodiments of the present application.

[0058] See also Figure 1The vehicle-mounted oxygen generator in the embodiment of the present application includes an air intake module 100, an oxygen generator module 200 and a control module 300, wherein the air intake module 100 is arranged in a heating and air conditioning device of the vehicle, and the air intake module 100 and the oxygen generator module 200 are ventilated and connected;

[0059] The control module 300 is configured to obtain current status information of the vehicle, and control the air intake module 100 to obtain air from the outside and / or control the oxygen production module 200 to produce oxygen using the air obtained from the outside by the air intake module 100 according to the current status information, so as to control the oxygen concentration in the vehicle cabin, wherein the current status information includes the current positioning information of the vehicle and the oxygen concentration information in the vehicle cabin of the vehicle.

[0060] In some embodiments, the control module 300 includes a positioning component and an oxygen concentration measurement component. The positioning component is configured to obtain current positioning information, and the oxygen concentration measurement component is configured to obtain oxygen concentration information.

[0061] Specifically, the vehicle-mounted oxygen generator in the above embodiment is arranged in the vehicle. The air intake module 100 is generally arranged in the vehicle's heating and air conditioning device, that is, the HAVC device, and its function of obtaining air from the outside can be directly realized based on the vehicle's HAVC device. When the vehicle's HAVC device is running, based on the current driving state of the vehicle or the air compression function of the vehicle's HAVC device itself, air can be inhaled from the external environment, so as to facilitate the subsequent use of the above-mentioned air for oxygen separation.

[0062] The oxygen production module 200 is generally arranged in the central armrest cabinet, trunk or engine compartment of the vehicle, and is ventilatedly connected to the air intake module 100. The air obtained by the air intake module 100 from the outside can be introduced into the oxygen production module 200 through the connection relationship between the air intake module 100 and the oxygen production module 200 separates the oxygen in the air by separating the above air, and finally releases the oxygen into the vehicle cabin.

[0063] In order to control the oxygen concentration in the vehicle cabin so that the oxygen concentration in the vehicle cabin can be controlled within a preset concentration range that can make the user feel comfortable, the vehicle-mounted oxygen generator in the embodiment of the present application is also provided with a control module 300. The control module 300 is generally built into the vehicle-mounted system of the vehicle, for example, it can be built into the electronic control unit (ECU) of the vehicle, and the user can control it through touch, gesture, etc. on the central control screen or other screens of the vehicle or through voice commands to the vehicle-mounted system. The control module 300 has a communication connection relationship with the air intake module 100 and the oxygen production module 200. The control module 300 can control the operation of the air intake module 100 and the oxygen production module 200 in the form of instructions to control the air intake process of the air intake module 100 and the oxygen production process of the oxygen production module 200, such as controlling the rate at which the air intake module 100 obtains air from the outside, controlling the oxygen production rate of the oxygen production module 200, etc.

[0064] It should be noted that the control of the air intake module 100 and the oxygen production module 200 by the control module 300 is mainly based on the current state parameters of the vehicle, which generally include the current positioning information of the vehicle and the oxygen concentration information in the vehicle cabin, wherein the current positioning information of the vehicle is generally satellite positioning information, which can be used to confirm the current speed and acceleration information of the vehicle, and then indirectly control the air intake process of the air intake module 100 according to the speed and acceleration information. In addition, illustratively, with the help of auxiliary means such as altitude measurement, the control module 300 can also obtain the altitude of the position corresponding to the positioning information according to the above-mentioned current positioning information, thereby indirectly determining the oxygen concentration of the external environment where the vehicle is located, and then assisting the control module 300 to adjust the oxygen production progress of the oxygen production module 200. In addition, the oxygen concentration information in the vehicle cabin can directly reflect the current oxygen concentration in the vehicle cabin. In addition, since the number of passengers in the vehicle cabin will also affect the oxygen consumption in the vehicle cabin and thus affect the oxygen concentration, illustratively, the current status information may also include the number of passengers in the vehicle. The control module 300 can control the oxygen production process of the oxygen production module 200 according to the number of passengers in the vehicle cabin, and control the oxygen concentration in the vehicle cabin by increasing the oxygen production amount, so that the oxygen concentration can be adapted to the number of passengers to avoid passengers from experiencing discomfort symptoms such as hypoxia and altitude sickness.

[0065] In order to obtain the current state information of the vehicle, the control module 300 is provided with corresponding information collection components, such as a positioning component and an oxygen concentration measurement component, wherein the positioning component is used to obtain the current positioning information of the vehicle, and the current positioning information obtained generally includes the current longitude, latitude and satellite altitude information of the vehicle. In the process that the current positioning information changes with the vehicle driving, the control module 300 can calculate the vehicle's driving speed, driving acceleration and other information according to the change of the current positioning information. At the same time, if the positioning component is also equipped with an auxiliary function of altitude calculation, the altitude corresponding to the current position can be obtained according to the above-mentioned satellite altitude information combined with the altitude calculation, and the oxygen thinness of the external environment at the current position can be further calculated according to the altitude, so as to know the oxygen concentration in the external environment. In addition, in order to determine the above-mentioned altitude and further determine the oxygen concentration in the external environment, the following method can also be adopted: the current air pressure change information of the external environment is obtained by a pressure sensor, and then compared with the standard atmospheric pressure or a preset reference atmospheric pressure, that is, the altitude of the current environment can be obtained, and then the oxygen thinness of the external environment at the current position can be calculated, so as to know the oxygen concentration in the external environment. In addition, the oxygen concentration measurement component is generally arranged in the vehicle cabin, and can generally be arranged as an oxygen concentration measurement sensor, which can directly detect the air in the vehicle cabin, and then detect the current oxygen concentration in the vehicle cabin. After the ECU obtains the above oxygen concentration from the oxygen concentration measurement sensor, it can use it as a reference to control the oxygen production process of the oxygen production module 200, thereby controlling the oxygen concentration in the vehicle cabin within a reasonable range to ensure that the passengers in the vehicle cabin feel comfortable.

[0066] See also Figure 2 In some embodiments, the air intake module 100 includes an air compression component 110 and a gas pre-treatment component 120, and the air compression component 110 is ventilatedly connected to the gas pre-treatment component 120;

[0067] The air compression assembly 110 is configured to be controlled by the control module 300 to obtain air from the outside and introduce the air into the oxygen production module 200;

[0068] The gas pre-processing component 120 is configured to perform pre-processing on the acquired air so that the physical and chemical properties of the air meet preset conditions.

[0069] In some embodiments, the gas pretreatment component 120 includes an air filter 121, an exhaust radiator 122, and a steam-water separator 123, the air filter 121 is configured to perform filtering processing on the acquired air, the exhaust radiator 122 is configured to perform temperature control processing on the acquired air, and the steam-water separator 123 is configured to perform dehumidification processing on the acquired air.

[0070] In some embodiments, the air intake module 100 further includes a sensor assembly, which is configured to detect the physical and chemical properties of the air acquired by the air intake module, wherein the physical and chemical properties include temperature, humidity and / or pressure;

[0071] The control module 300 is further configured to control the operation mode of the air compression component 110 according to the physical and chemical properties and the current state information, so as to control the amount of air obtained by the air compression component 110 from the outside.

[0072] In some embodiments, when the temperature of the air obtained by the air intake module 100 from the outside is lower than a preset first temperature threshold, the control module 300 is configured to control the air intake module 100 to perform a preheating action until the temperature of the air is higher than or equal to a preset second temperature threshold.

[0073] Specifically, see Figure 2 The structure of the air intake module 100 is as follows: Figure 2 It is schematically shown that in the process of the air intake module 100 obtaining air from the outside, the air first passes through the air intake grille 41 in the vehicle HAVC device. In order to minimize the probability of impurities in the air damaging the air intake module 100, illustratively, the gas pretreatment component 120 of the air intake module 100 includes an air filter 121. The air filter 121 can perform preliminary coarse filtration on the air entering the vehicle HAVC device from the outside, remove larger particles such as dust in the air, and prevent large particles from clogging the airway or causing damage to various components in the air intake module 100. The obtained air is introduced into the air compression component 110 of the air intake module 100 via the air filter 121.

[0074] Exemplarily, the air compression assembly 110 includes an air compressor 111 and a blower 112. The air compressor 111 introduces air from the outside into the air intake module 100 by operating to generate negative pressure, and further transports the introduced air to the oxygen production module 200 by operating. Its operating speed is regulated by the control module 300, thereby achieving direct control of the air intake effect. The blower 112 is controlled by the control module 300 to control the air compression effect of the air compressor 111 by blowing air to the air compressor 111, thereby indirectly achieving control of the air intake effect.

[0075] Before the air compressor 111 delivers the introduced air to the oxygen production module 200, since the oxygen production module 200 has requirements for the physical and chemical properties of the introduced air, if the physical and chemical properties of the introduced air do not meet the requirements of the oxygen production module 200 in terms of temperature, humidity and other physical and chemical properties, it will significantly affect the oxygen production effect of the oxygen production module 200, and may even cause the oxygen production module 200 to fail. Therefore, in order to cope with the above situation, illustratively, the gas pretreatment component 120 of the air intake module 100 also includes an exhaust radiator 122 and a steam-water separator 123, wherein the exhaust radiator 122 mainly controls the temperature of the air delivered to the oxygen production module 200 by the air compressor 111, so that the temperature of the air delivered to the oxygen production module 200 is controlled within a range suitable for the oxygen production module 200 to produce oxygen, and the steam-water separator 123 mainly dehumidifies the air delivered to the oxygen production module 200 by the air compressor 111, removes water vapor and liquid water droplets in the air, and prevents liquid water or gaseous water from interfering with the oxygen production process of the oxygen production module 200. It should be noted that Figure 2 Although the exhaust radiator 122 and the steam-water separator 123 are drawn in the order shown in the figure, the actual configuration order of the two can be adjusted according to the actual situation. Figure 2 After being processed by the exhaust radiator 122 and the steam-water separator 123 , the air output by the air compressor 111 enters the oxygen production module 200 .

[0076] In order to monitor the above-mentioned gas pretreatment, the air intake module 100 also includes a sensor module ( Figure 2 (not shown in the figure), the sensor module includes multiple sensors for different parameters, which are installed inside the gas channel of the air intake module 100. Generally, the above-mentioned sensors include at least a temperature sensor, a humidity sensor and an air pressure sensor, which can respectively monitor the physical and chemical properties of the air in the airway, such as temperature, humidity and air pressure, so that the control module 300 can adjust the control method of the air intake module 100 at any time according to the physical and chemical properties of the air obtained by the air intake module 100, such as controlling the operation of the blower 112 according to the air pressure, and controlling the operation rate of the air compressor 111 according to the temperature and humidity.

[0077] Furthermore, since the temperature of the external environment may be at a relatively low level in high altitude areas, if the external temperature is lower than the pre-start temperature of the air compressor 111 (corresponding to the first temperature threshold), the working conditions of the air compressor 111 cannot be met, and the air compressor 111 cannot start and work normally. In order to ensure that the air compressor 111 in the air intake module 100 can start normally, illustratively, when the temperature sensor in the above-mentioned sensor module detects that the gas temperature inside the airway is lower than the pre-start temperature of the air compressor 111, the control module 300 issues an idling preheating instruction to the air compressor 111, and the air compressor 111 responds to the instruction to perform an idling preheating process until the temperature of the air compressor 111 reaches its working temperature (corresponding to the second temperature threshold) and stops preheating. At this time, the air compressor 111 reaches a normal working state and can obtain air from the outside through operation.

[0078] See also Figure 3 In some embodiments, the oxygen production module 200 includes a first solenoid valve assembly 210, a molecular sieve assembly 220, and a first gas storage assembly 230, and the first solenoid valve assembly 210, the molecular sieve assembly 220, and the first gas storage assembly 230 are ventilated and connected in sequence;

[0079] The molecular sieve assembly 220 is configured to separate oxygen from the gas entering the molecular sieve assembly;

[0080] The first solenoid valve assembly 210 is configured to be controlled by the control module 300 to control the air obtained by the air intake module 100 to enter the molecular sieve assembly 220, and to control the oxygen separated by the molecular sieve assembly 220 to enter the first gas storage assembly 230;

[0081] The first gas storage assembly 230 is configured to store the oxygen separated by the molecular sieve assembly 220 .

[0082] Specifically, see Figure 3 The structure of the oxygen production module 200 is as follows: Figure 3As schematically shown, the air intake module 100 delivers the acquired air to the first solenoid valve assembly 210 of the oxygen production module 200. The first solenoid valve assembly 210 is controlled by the control module 300 to restrict the opening and closing of two groups of airways. One is to restrict the air delivered by the air intake module 100 to the first airway of the molecular sieve assembly 220, and the other is to restrict the second airway to release the oxygen separated by the molecular sieve assembly 220 to the vehicle cabin and the first air storage assembly 230. When the air delivered to the oxygen production module 200 by the air intake module 100 reaches the first solenoid valve assembly 210, it is controlled by the control assembly 300, and the first solenoid valve assembly 210 opens the above-mentioned first airway to introduce the air into the molecular sieve assembly 220. The molecular sieve assembly 220 uses the introduced air for separation processing. Thereafter, the first solenoid valve assembly 210 opens the above-mentioned second airway to introduce the generated oxygen into the first gas storage assembly 230 for storage, or releases the generated oxygen into the vehicle cabin. In addition, the first gas storage assembly 230 can also be controlled by the control module 300 to release the stored oxygen into the vehicle cabin to achieve regulation of the oxygen concentration in the vehicle cabin.

[0083] See also Figure 4 In some embodiments, the vehicle-mounted oxygen generator further includes an oxygen supply module 400, which is configured to be controlled by the control module 300 to release the oxygen produced by the oxygen production module 200 to the vehicle cabin;

[0084] The oxygen supply module 400 includes a second solenoid valve assembly 410, a second gas storage assembly 420 and an oxygen release assembly 430, and the second solenoid valve assembly 410, the second gas storage assembly 420 and the oxygen release assembly 430 are ventilated and connected;

[0085] The second solenoid valve assembly 410 is configured to be controlled by the control module 300 to control the oxygen generated by the oxygen production module 200 to enter the oxygen release assembly 430 and / or be stored in the second gas storage assembly 420;

[0086] The oxygen release assembly 430 is configured to release oxygen into the vehicle cabin under the control of the control module 300;

[0087] The second gas storage assembly 420 is configured to store oxygen under the control of the control module 300 , and the second gas storage assembly 420 can be disassembled for separate oxygen inhalation.

[0088] In certain embodiments, the oxygen release assembly 430 includes a mask release member 431 and a diffuser release member 432 , wherein the mask release member 431 is configured to connect to an external oxygen mask and the diffuser release member 432 is configured to diffusely release oxygen into the vehicle cabin.

[0089] Specifically, in order to improve the effect of releasing oxygen into the vehicle cabin and avoid waste of oxygen, the vehicle-mounted oxygen generator in the embodiment of the present application further includes an oxygen supply module 400. Figure 4 The structure of the oxygen supply module 400 is as follows: Figure 4 It is schematically shown that, based on the above embodiment, the oxygen produced by the oxygen production module 200 needs to be introduced into the oxygen supply module 400 in two ways, as shown in FIG. Figure 3 , one way is for the molecular sieve component 220 in the oxygen production module 200 to generate oxygen and then directly introduce it into the oxygen supply module 400, and the other way is for the oxygen stored in the first gas storage component 230 in the oxygen production module 200 to be introduced into the oxygen supply module 400. The above two ways of oxygen are introduced into the second solenoid valve component 410 of the oxygen supply module 400. When the oxygen concentration in the vehicle cabin measured by the oxygen concentration measurement component in the control module 300 has not reached the preset upper limit value, the control module 300 controls the second solenoid valve component 410 to directly transport the introduced oxygen to the oxygen release component 430 for release, so that the oxygen concentration in the vehicle cabin rises steadily. When the oxygen concentration in the vehicle cabin measured by the oxygen concentration measurement component has reached the preset upper limit value, the control module 300 controls the second solenoid valve component 410 to change the state, and transport the introduced oxygen to the second gas storage component 420 for storage, so as to avoid the waste of the generated oxygen. For example, the second gas storage assembly 420 is a detachable structure, and the user can remove the second gas storage assembly 420 separately for oxygen storage, and can achieve additional oxygen absorption by connecting an external oxygen absorption device. In addition, if an emergency occurs in the vehicle cabin and causes a sudden drop in oxygen concentration, the control module 300 can also control the second solenoid valve assembly 410 to change state, take out the oxygen stored in the second gas storage assembly 420 and transfer it to the oxygen release assembly 430 and release it into the vehicle cabin, thereby achieving emergency oxygen replenishment in the vehicle cabin.

[0090] Exemplarily, in order to increase the diversity of oxygen release forms and meet the different needs of users for oxygen, the oxygen release component 430 includes at least two release components, namely, a mask release component 431 and a diffusion release component 432. The mask release component 431 is generally configured as an oxygen mask interface, and an external oxygen mask can be directly connected to the mask release component 431 through an air duct. When the mask release component 431 releases oxygen, the user can directly inhale oxygen through the oxygen mask. The diffusion release component 432 is generally configured as an air outlet with a grille, and the air outlet of the vehicle HAVC can be used as the above-mentioned diffusion release component 432. Oxygen is diffused into the vehicle cabin through the diffusion release component 432 to directly increase the oxygen concentration in the vehicle cabin.

[0091] Furthermore, in order to prevent other gases such as carbon dioxide and water vapor exhaled by the user from flowing back into the airway of the oxygen release component 430 when releasing oxygen, a one-way valve is provided in each airway of the oxygen release component 430 to prevent gas from flowing back. Figure 4 The airway corresponding to the mask release member 431 is provided with a one-way valve A, and the airway corresponding to the diffusion release member 432 is provided with a one-way valve B. Under the action of the one-way valve, the gas in the above airway is only allowed to flow along the direction of the second solenoid valve assembly 410 to the oxygen release assembly 430, and reverse reflux is not allowed.

[0092] In this way, the vehicle oxygen generator in the present application can control the air intake and oxygen production process based on the vehicle's current positioning information and the oxygen concentration information inside the vehicle, thereby realizing the control of the oxygen concentration inside the vehicle cabin, improving the control effect of the vehicle's air intake and oxygen production in high altitude areas, and maintaining the oxygen concentration inside the vehicle cabin within a preset range. The oxygen generator can also be integrated with the vehicle's heating and air-conditioning system to effectively reduce the space occupied inside the vehicle.

[0093] Next, a method for actually performing oxygen production by the above-mentioned vehicle-mounted oxygen production device will be described.

[0094] See also Figure 5 The vehicle-mounted oxygen production method in the embodiment of the present application is used in the control module 300 in the vehicle-mounted oxygen production device in the above embodiment, and the method includes the following steps:

[0095] 01: Get the current status information of the vehicle;

[0096] 02: According to the current state information, control the air intake module 100 to obtain air from the outside;

[0097] 03: The control oxygen production module 200 uses the air obtained from the outside by the air intake module 100 to produce oxygen to control the oxygen concentration in the vehicle cabin.

[0098] On this basis, step 01 includes:

[0099] Control the positioning component to obtain the current positioning information of the vehicle;

[0100] Controlling the oxygen concentration measuring component to obtain oxygen concentration information;

[0101] Step 02 includes:

[0102] Determine the reference oxygen concentration in the vehicle cabin according to the current positioning information and oxygen concentration information;

[0103] In response to a user's selection operation for a reference oxygen concentration, the air intake module 100 is controlled to obtain air from the outside according to the selected reference oxygen concentration.

[0104] Specifically, before starting to produce oxygen, the control module 300 first obtains the current positioning information of the vehicle based on the positioning component, obtains the oxygen concentration information in the vehicle cabin based on the oxygen concentration measurement component, and uses the current positioning information to determine the current driving speed and driving acceleration information of the vehicle. With the assistance of elevation measurement, the altitude of the current location of the vehicle can also be determined. The control module 300 summarizes and calculates the above information to obtain the reference oxygen concentration in the current vehicle cabin. Generally, the above reference oxygen concentration is the upper limit of the oxygen concentration that the user can feel comfortable in the current vehicle cabin.

[0105] Based on the above reference oxygen concentration, the control module 300 can obtain one or more corresponding oxygen supply control modes, and send the above oxygen supply control modes to the central control screen or other display screen of the vehicle for the user to confirm or select. When the user makes a selection operation through voice command, touch or gesture control, and selects a certain oxygen supply control mode, the control module 300 controls the air intake module 100 to obtain air from the outside according to the reference oxygen concentration corresponding to the oxygen supply control mode, so as to ensure that the amount of air obtained and the acquisition rate can ensure that the oxygen generated after the oxygen production action of the oxygen production module 200 can meet the above reference oxygen concentration.

[0106] In certain embodiments, the on-board oxygen production method further comprises:

[0107] When the temperature of the air acquired by the air intake module 100 from the outside is lower than the preset first temperature threshold, the air intake module 100 is controlled to perform a preheating action until the temperature of the air is higher than or equal to the preset second temperature threshold.

[0108] Specifically, since the temperature of the external environment may be at a relatively low level in high altitude areas, if the external temperature is lower than the pre-start temperature of the air compressor 111 (corresponding to the first temperature threshold), the working conditions of the air compressor 111 cannot be met, and the air compressor 111 cannot start and work normally. In order to ensure that the air compressor 111 in the air intake module 100 can start normally, illustratively, when the temperature sensor in the above-mentioned sensor module detects that the gas temperature inside the airway is lower than the pre-start temperature of the air compressor 111, the control module 300 issues an idling preheating instruction to the air compressor 111, and the air compressor 111 responds to the instruction to perform an idling preheating process until the temperature of the air compressor 111 reaches its working temperature (corresponding to the second temperature threshold) and stops preheating. At this time, the air compressor 111 reaches a normal working state and can obtain air from the outside through operation.

[0109] In some embodiments, step 02 further includes:

[0110] According to the physical and chemical properties of the air acquired by the air intake module 100 and the current state information, the operation rate of the air compression component 110 of the air intake module 100 is controlled to control the amount of air acquired by the air compression component 110 from the outside.

[0111] Specifically, in some examples, when the control module 300 determines that the vehicle is accelerating according to the current position information of the vehicle, the control module 300 controls the operation rate of the air compressor 111 in the air compression component 110 to increase, so as to adaptively increase the intake volume. For another example, in some examples, when the control module 300 determines the driving speed of the vehicle according to the current positioning information of the vehicle, and uses the above-mentioned driving speed and the current intake cross-section of the air intake grille 51 to detect whether the current intake volume can meet the intake volume required for oxygen production, when the control module 300 detects that the current intake volume cannot meet the intake volume required for oxygen production, the control module 300 controls the operation rate of the air compressor 111 in the air compression component 110 to increase the intake volume, etc. For another example, in some examples, passengers are using the air conditioning system in the vehicle cabin. In order to take into account the operation of the air conditioning system at the same time, the control module 300 controls the air compression component 110 to adjust the operation rate so that the intake volume can meet the use of oxygen production and air conditioning at the same time.

[0112] In some embodiments, step 03 includes:

[0113] According to the current state information, the first solenoid valve assembly 210 of the oxygen production module 200 is controlled to switch to the first operating state, so that the air obtained from the outside by the air intake module 100 enters the molecular sieve assembly 220 of the oxygen production module 200;

[0114] The first solenoid valve assembly 210 is controlled to switch to the second operating state, so that the oxygen separated by the molecular sieve assembly 220 is stored in the first gas storage assembly 230 of the oxygen production module 200 .

[0115] Specifically, when the control module 300 determines the driving speed and driving acceleration of the vehicle according to the current positioning information of the vehicle, combined with the oxygen concentration inside the vehicle cabin, the first solenoid valve assembly 210 of the oxygen production module 200 is controlled to open the first airway in the above embodiment (corresponding to the first operating state), so that the air delivered by the air intake module 100 enters the molecular sieve assembly 220 for separation and oxygen production. In the case where oxygen is generated during the separation and oxygen production process of the molecular sieve assembly 220, the control module 300 controls the first solenoid valve assembly 210 to open the second airway in the above embodiment (corresponding to the second operating state), and releases the oxygen separated by the molecular sieve assembly 220 into the vehicle cabin or introduces it into the first gas storage assembly 230 for storage. In addition, illustratively, the oxygen stored in the first gas storage assembly 230 can also be controlled by the control module 300 to be released into the vehicle cabin to complete the control of the oxygen concentration in the vehicle cabin.

[0116] Clear reference Figure 6 In certain embodiments, the vehicle-mounted oxygen production method further comprises:

[0117] 041: According to the current state information, the second solenoid valve assembly 410 of the oxygen supply module 400 is controlled to change its state so that the oxygen produced by the oxygen production module 200 is stored in the second gas storage assembly 420 of the oxygen supply module 400 and / or enters the oxygen release assembly 430 of the oxygen supply module 400;

[0118] 042: Controlling the oxygen release component 430 to release oxygen into the vehicle cabin;

[0119] 043: Control the second gas storage component 420 to store oxygen.

[0120] Specifically, based on the above-mentioned embodiment, the oxygen produced by the oxygen production module 200 needs to be introduced into the oxygen supply module 400 in two ways, as shown in FIG. Figure 3, one way is for the molecular sieve component 220 in the oxygen production module 200 to generate oxygen and then directly introduce it into the oxygen supply module 400, and the other way is for the oxygen stored in the first gas storage component 230 in the oxygen production module 200 to be introduced into the oxygen supply module 400. The above two ways of oxygen are introduced into the second solenoid valve component 410 of the oxygen supply module 400. When the oxygen concentration in the vehicle cabin measured by the oxygen concentration measurement component in the control module 300 has not reached the preset upper limit value, the control module 300 controls the second solenoid valve component 410 to change the state, and directly delivers the introduced oxygen to the oxygen release component 430 for release, so that the oxygen concentration in the vehicle cabin rises steadily. When the oxygen concentration in the vehicle cabin measured by the oxygen concentration measurement component has reached the preset upper limit value, the control module 300 controls the second solenoid valve component 410 to change the state, and delivers the introduced oxygen to the second gas storage component 420 for storage, so as to avoid the waste of the generated oxygen. Exemplarily, the second gas storage assembly 420 is a detachable structure, and the user can remove the second gas storage assembly 420 separately for oxygen storage, and can achieve additional oxygen absorption by means of an external oxygen absorption device. In addition to the above-mentioned detachable situation, the second solenoid valve assembly 410 and the second gas storage assembly 420 can be set to a two-way ventilation connection. In extreme cases, if the vehicle-mounted oxygen generator in the above-mentioned embodiment fails to generate oxygen, and the oxygen stored in the first gas storage assembly 230 in the above-mentioned embodiment is exhausted, that is, if the oxygen generator module 200 cannot introduce oxygen to the oxygen supply module 400, the control module 300 can control the change of the operating state of the second solenoid valve assembly 410, so that the second gas storage assembly 420 can supply oxygen to the vehicle cabin through the second solenoid valve assembly 410 through the oxygen release assembly 430, thereby realizing emergency oxygen supply.

[0121] In addition, illustratively, if an emergency occurs in the vehicle cabin causing a sudden drop in oxygen concentration, the control module 300 can also control the second solenoid valve assembly 410 to change state, take out the oxygen stored in the second gas storage assembly 420 and transfer it to the oxygen release assembly 430 and release it into the vehicle cabin, thereby achieving emergency replenishment of oxygen in the vehicle cabin.

[0122] The electronic device in the embodiment of the present application can act as the control module 300 in the above-mentioned vehicle-mounted oxygen production device, and the electronic device can implement the above-mentioned vehicle-mounted oxygen production method.

[0123] The vehicle in the embodiment of the present application includes the above-mentioned vehicle-mounted oxygen production device, and the vehicle can implement the above-mentioned vehicle-mounted oxygen production method.
