Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicles, in particular to an oxygen production system, a vehicle and an oxygen supply method. BACKGROUND

[0002] With the increasing attention to healthy travel, the problem of air quality in the vehicle is widely concerned. In particular, in a closed or semi-closed vehicle environment, the decrease of oxygen concentration may adversely affect the health and driving safety of the driver and passengers. Specifically, if the air circulation between the inside and outside of the vehicle is limited, or the oxygen content outside the vehicle is low (such as in high altitude areas), the oxygen content inside the vehicle will gradually decrease, which may cause dizziness, slow reaction, and lack of concentration of the driver and passengers, especially in high altitude areas, which may even induce health risks such as altitude sickness and difficulty breathing.

[0003] To this end, by using a vehicle-mounted oxygen production system that can actively produce oxygen, the problem of insufficient oxygen in the vehicle can be solved. However, in related technologies, the vehicle-mounted oxygen production system usually adopts a whole-vehicle diffusion oxygen supply mode or a nasal suction oxygen supply mode. The whole-vehicle diffusion oxygen supply mode directly inputs the oxygen produced by the vehicle-mounted oxygen production system into the cabin. In order to ensure that the oxygen concentration in the whole vehicle meets the standard, the vehicle-mounted oxygen production system needs to be continuously operated to deliver a large amount of oxygen, resulting in high energy consumption and low oxygen utilization efficiency. Moreover, due to the hysteresis of oxygen diffusion in the vehicle, the actual inhaled oxygen concentration of the driver and passengers is slowly improved. The nasal suction oxygen supply mode is to install a nasal suction device for the driver and passengers at the seat headrest or the roof of the vehicle, so as to directly send high-concentration oxygen to the mouth and nose of the driver and passengers through the nasal suction device. This mode requires the driver and passengers to additionally wear the nasal suction device, which may cause discomfort and inconvenience, and affect the driving experience and comfort of the driver and passengers.

[0024] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings.

[0025] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and in the above-described drawings are used to distinguish similar objects, and do not necessarily have to be used to describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the application described herein can be implemented in an order other than that illustrated or described herein.

[0026] In combination Figure 1 As shown in the drawings, the embodiments of the present application provide an oxygen production system, comprising: An oxygen production mechanism for producing oxygen; A jet mechanism 1 for directing the jet of oxygen into the cabin 3; the oxygen input port of the jet mechanism 1 is in communication with the oxygen output port of the oxygen production mechanism; A pose adjustment mechanism 2 for carrying and driving the jet mechanism 1 to adjust the spatial position of the jet mechanism 1 in the cabin 3 and the direction of the jet.

[0027] In the embodiments, the oxygen production system can be applied to a transportation tool such as a vehicle, a ship, an aircraft, a spacecraft, etc. having a cabin 3 (a space for the driver or passenger to sit or move), and the oxygen production system produces oxygen to provide at least oxygen-enriched gas in the cabin 3, thereby meeting the oxygen inhalation needs of the driver or passenger in the cabin 3 and improving the driving experience of the driver or passenger.

[0028] Specifically, the oxygen production mechanism of the oxygen production system is used for oxygen (or oxygen-enriched gas) production, which can be arranged in the spare structure space (such as the trunk, chassis, etc. of the vehicle) of the corresponding transportation tool, so as to make full use of the spare area, avoid occupying the space used by the driver or passenger in the cabin 3, and reduce the influence of noise, vibration, airflow, etc. of the driver or passenger in the cabin 3 when the oxygen production mechanism is running. In some embodiments, the oxygen production mechanism can use mature oxygen production technologies such as pressure swing adsorption to produce high-purity oxygen, for example, by using the difference in adsorption capacity of molecular sieve for oxygen and nitrogen under different pressure conditions, through a periodic process of pressurization and depressurization, the effective separation of oxygen and nitrogen in air is realized, so as to obtain high-concentration oxygen based on air at room temperature.

[0029] The injection mechanism 1 of the oxygen production system can be arranged in the cabin 3 or on the cabin 3 wall (such as the vehicle cabin 3 corresponding to the vehicle body 4 structure), and the oxygen input port of the injection mechanism 1 is communicated with the oxygen output port of the oxygen production mechanism, so as to direct the injection of the oxygen-enriched gas produced and output by the oxygen production mechanism to the breathing area (such as the oral and nasal cavity) of the driver and passenger in the cabin 3, so as to improve the targeting and efficiency of oxygen supply. Compared with the traditional diffused oxygen supply mode, the directional injection oxygen supply mode in the embodiment can quickly increase the local oxygen concentration of the breathing area of the driver and passenger in the cabin 3, realize rapid local oxygen enrichment, and meet the oxygen inhalation demand of the driver and passenger without oxygen gradually diffusing to the entire cabin 3. On the one hand, it is convenient to realize rapid and effective oxygen supply intervention in the case of hypoxia (such as in the plateau environment, long-time driving or sudden physiological discomfort, etc.) or the need for emergency oxygen supply, the oxygen supply effect is fast, and the driving safety and comfort of the driver and passenger can be effectively improved. On the other hand, since the oxygen supply area of the directional injection oxygen supply mode is concentrated and the oxygen utilization rate is high, the oxygen output and the overall energy consumption of the oxygen production system required to meet the oxygen inhalation demand of the driver and passenger can be significantly reduced, the energy utilization efficiency of the oxygen production system is effectively improved, energy waste is avoided, and the service life of the oxygen production system is prolonged. On the other hand, the directional injection oxygen supply mode avoids the situation that oxygen diffuses irregularly in the cabin 3 and easily leaks to the outside of the cabin 3 through the gap of the cabin door (such as the vehicle door), the ventilation system and other structures in the traditional diffused oxygen supply mode, thereby overcoming the problems of slow oxygen concentration increase speed and low oxygen utilization rate in the cabin 3. By concentrating and directing the injection of the oxygen-enriched gas to the breathing area of the driver and passenger in the cabin 3, the oxygen supply efficiency is improved, and the waste of oxygen resources is reduced, which helps to realize faster oxygen concentration response and better meet the instantaneity and reliability demand of the driver and passenger for oxygen supply in a specific environment (such as closed, plateau or long-time riding, etc.). Compared with the traditional nasal inhalation oxygen supply mode relying on wearing respiratory equipment, the directional injection oxygen supply mode in the embodiment can realize non-invasive and efficient oxygen inhalation without wearing respiratory equipment by the driver and passenger, avoiding the problems of wearing respiratory equipment, such as discomfort and inconvenience, and is easy to be accepted by the driver and passenger, and improves the comfort and convenience of the driver and passenger for oxygen inhalation, and improves the driving experience of the driver and passenger.

[0030] The pose adjusting mechanism 2 of the oxygen generating system can be arranged in the cabin 3 or on the cabin wall. For the cabin 3 of a vehicle, the pose adjusting mechanism 2 can be arranged at a side wall area or a roof area of the vehicle body 4 corresponding to the cabin 3, so as to avoid interference with the head, limbs and other moving spaces of the driver and passenger, thereby improving the space utilization and comfort of the cabin 3. The pose adjusting mechanism 2 is used to carry and drive the spraying mechanism 1, such as driving the spraying mechanism 1 to adjust the position and angle relative to the cabin 3, so as to realize the adjustment of the spatial position and directional spraying direction of the spraying mechanism 1 in the cabin 3, thereby facilitating the adjustment of the directional spraying oxygen supply position and angle of the spraying mechanism 1 according to the breathing area (such as the mouth and nasal cavity) of the driver and passenger, so as to flexibly direct the oxygen to the breathing area of the driver and passenger.

[0031] The pose adjusting mechanism 2 can be manually controlled or automatically controlled. Manual control means that the driver and passenger controls the pose adjusting mechanism 2 according to their own needs, thereby realizing the corresponding driving of the spraying mechanism 1. Automatic control means that based on the sensors arranged in the cabin 3, the specific position, posture and breathing area of the driver and passenger are automatically recognized, and the pose adjusting mechanism 2 is automatically calculated and driven to act based on the preset control algorithm, thereby intelligently adjusting the spatial position and spraying angle of the spraying mechanism 1 to accurately align the breathing area of the driver and passenger for oxygen supply. In this way, the adjustment mode of the pose adjusting mechanism 2 and the spraying mechanism 1 is diversified, the adaptability and oxygen supply flexibility of the oxygen generating system in different use scenarios are improved, the individualized oxygen supply needs of different drivers and passengers are met, and the intelligent degree and use experience of the driver and passenger of the oxygen generating system are further improved.

[0032] In summary, the oxygen generating system can be used to generate oxygen and supply the oxygen-enriched gas to the passengers in the corresponding cabin 3 in a targeted manner to meet their oxygen inhalation needs, improve the driving experience and health protection level. Specifically, the oxygen generating mechanism of the oxygen generating system is used to generate oxygen, and the injection mechanism 1 for supplying oxygen by the oxygen generating mechanism is used to accurately direct the injection of the oxygen-enriched gas output by the oxygen generating mechanism to the breathing area of the passengers based on the pose adjustment mechanism 2, so that the oxygen supply of the oxygen generating system is more efficient, timely and targeted, and is especially suitable for hypoxic or emergency oxygen supply scenarios such as high altitude, enclosed space or long time riding. Among them, the pose adjustment mechanism 2 is used to carry and drive the injection mechanism 1 to adjust the spatial position and directional injection direction of the injection mechanism 1 in the cabin 3, so as to obtain the best oxygen supply position and angle matched with the breathing area of the passengers, realize the accurate coverage of the oxygen-enriched gas to the breathing area of the passengers, and greatly improve the oxygen supply efficiency and comfort. In addition, compared with the traditional diffused oxygen supply mode, the oxygen generating system in the embodiment can realize directional injection oxygen supply, can significantly improve the local oxygen concentration response speed and oxygen supply efficiency, reduce oxygen diffusion loss and leakage in and out of the cabin 3, effectively reduce the overall oxygen consumption and system energy consumption (such as the energy consumption required for oxygen supply of the oxygen generating system), prolong the service life of the oxygen generating system; compared with the traditional nasal inhalation equipment, the oxygen generating system in the embodiment does not need to wear a breathing appliance, is convenient to use, has high comfort, and has stronger acceptance of the passengers.

[0033] Optionally, the oxygen generating system further comprises a gas storage mechanism, and the oxygen input port of the injection mechanism 1 and the oxygen output port of the oxygen generating mechanism are communicated through the gas storage mechanism and corresponding pipelines.

[0034] In this embodiment, the oxygen production system is provided with a gas storage mechanism (such as a gas storage tank), the oxygen input port of the gas storage mechanism is in communication with the oxygen output port of the oxygen production mechanism through a corresponding connecting pipeline (or gas pipe), and the oxygen output port of the gas storage mechanism is in communication with the oxygen input port of the injection mechanism 1 through a corresponding connecting pipeline; the gas storage mechanism can be used to store oxygen after the oxygen production mechanism produces oxygen, and can be used to ensure the continuity and stability of the oxygen supply of the injection mechanism 1. Specifically, the gas storage mechanism has a pressure buffering function, can provide stable and continuous oxygen output in the case of intermittent operation of the oxygen production mechanism (or there is flow fluctuation in the oxygen output of the oxygen production mechanism) or short-time high-flow oxygen supply of the injection mechanism 1, realize stable gas source, avoid the discontinuous oxygen supply caused by oxygen production delay, and thus improve the stability and reliability of the overall oxygen supply of the oxygen production system; and the injection mechanism 1 can directly take gas from the gas storage tank when used for directional injection oxygen supply, which can effectively improve the oxygen supply response speed of the oxygen production system; and by providing the gas storage mechanism, the working frequency of the oxygen production mechanism can be reduced, that is, the oxygen production mechanism does not need to be kept in a running state for a long time, the service life of the oxygen production mechanism can be prolonged, and the energy consumption fluctuation of the oxygen production mechanism can be reduced. Moreover, the setting of the gas storage mechanism facilitates the decoupling of oxygen production and oxygen supply, that is, the oxygen production mechanism can continuously run in the background and continuously store gas through the gas storage mechanism, without the need for real-time synchronization with the injection oxygen supply action, which can improve the flexibility and energy saving of the overall oxygen production system. In addition, the gas storage mechanism is convenient to cooperate with the corresponding flow and pressure regulating devices to more accurately control the oxygen injection time, flow rate, pressure and other parameters, and meet the individualized needs of oxygen injection.

[0035] Optionally, the adjustment of the output parameters (such as oxygen injection pressure, flow rate, etc.) of the injection mechanism 1 can be controlled by the oxygen production mechanism. In the case where the oxygen production system is provided with a gas storage mechanism, the pressure and flow rate of the gas storage mechanism or its oxygen output port can be adjusted to accurately control the oxygen output of the injection mechanism 1, thereby realizing precise oxygen supply. In some embodiments, pressure regulating devices (such as pressure stabilizing valves), flow control devices (such as electrically controlled flow valves, proportional valves or pulse valves) and the like can also be used to dynamically adjust the state of the gas input into the injection mechanism 1, thereby realizing flexible and accurate control of the output of the injection mechanism 1.

[0036] Optionally, in combination with the injection mechanism 1 shown in Figures 1-3 , the injection mechanism 1 includes a gas nozzle, the pose adjustment mechanism 2 includes a position adjustment structure 21 and an angle adjustment structure 22, the position adjustment structure 21 is used to carry and drive the angle adjustment structure 22 to adjust the position of the angle adjustment structure 22 relative to the cabin 3; and the angle adjustment structure 22 is used to carry and drive the gas nozzle to adjust the angle of the gas nozzle relative to the cabin 3.

[0037] In this embodiment, to achieve flexible and accurate adjustment of the pose (position and attitude) of the injection mechanism 1, the pose adjustment mechanism 2 is provided with a position adjustment structure 21 and an angle adjustment structure 22. The position adjustment structure 21 can be arranged in the cabin 3 or on the cabin wall of the cabin 3, and is used to carry and drive the angle adjustment structure 22 to adjust the position of the angle adjustment structure 22 relative to the cabin 3, such as driving the angle adjustment structure 22 to change the spatial position relative to the cabin 3 within a certain range, for example, to realize translation in the up-down, front-back, and left-right directions, or to move on a corresponding spatial track, so that the position of the injection mechanism 1 arranged on the angle adjustment structure 22 has a certain variability, so as to adapt to the actual situation of the driver and passenger. The angle adjustment structure 22 is mounted on the position adjustment structure 21 and is used to carry and drive the injection mechanism 1 to adjust the angle of the injection mechanism 1 relative to the cabin 3, so that the orientation (injection direction) of the injection mechanism 1 can be adjusted within a certain angle range, for example, rotating around the pitch axis, yaw axis, or roll axis, thereby realizing accurate control of the gas injection direction.

[0038] To facilitate directional oxygen injection, the injection mechanism 1 is provided with a gas nozzle; the gas nozzle is in gas communication with the oxygen output end of the oxygen generating mechanism (or gas storage mechanism), and is used to inject oxygen-rich gas at a specific flow rate, pressure, and direction to a target area, such as the breathing area of the driver and passenger in the cabin 3, thereby improving oxygen supply efficiency and comfort. Among them, the gas nozzle can be selected in the form of a nozzle with a flow guiding structure or a flow rectifying function to optimize the gas flow injection form and avoid the reduction of oxygen supply efficiency caused by turbulent diffusion.

[0039] Exemplarily, as shown in Figures 1-3 The position adjustment structure 21 is arranged on the cabin wall and located in the cabin 3 (space), so as to avoid interfering with the activity space of the driver and passenger in the cabin 3 while ensuring effective carrying and driving of the injection mechanism 1 for directional injection of oxygen into the cabin 3. The position adjustment structure 21 includes a first driving structure (such as a motor) and a track, and the first driving structure is used to drive the track to move along a set track or guide, thereby realizing position adjustment of the angle adjustment structure 22 arranged on the track along a preset path in the cabin 3, and realizing position adjustment of the injection mechanism 1 arranged on the angle adjustment structure 22. The angle adjustment structure 22 includes a second driving structure (such as a steering engine, an electric rotating shaft, or a universal cloud platform), which is arranged on the track and moves with the track; the second driving structure is used to drive the angle adjustment of the injection mechanism, such as driving the injection mechanism to pitch, yaw, or rotate around one or more axes, and finally to adjust the angle relative to the cabin 3. In this way, based on the position adjustment structure 21 and the angle adjustment structure 22, the pose of the injection mechanism 1 is adjusted to ensure that the oxygen-rich gas is accurately injected to the breathing point of the driver and passenger through the injection mechanism 1, thereby improving the oxygen supply accuracy and efficiency.

[0040] Optionally, the air jet nozzle can be equipped with a replaceable spray head or a jet port structure with adjustable aperture to adapt to different oxygen inhalation requirements of different passengers or different jet distance and angle requirements, thereby improving the adaptability and use convenience of the oxygen generation system.

[0041] Optionally, the air jet nozzle can be integrated with a micro electromagnetic valve, a pulse driving element or a flow regulating mechanism, etc., so as to realize flexible control of the jet frequency, jet mode (such as continuous jet or pulse jet) and other parameters of the oxygen (or oxygen-enriched gas) at the oxygen supply end.

[0042] Optionally, a plurality of pose adjustment mechanisms 2 and jet mechanisms 1 are provided, and the pose adjustment mechanisms 2 and the jet mechanisms 1 correspond one-to-one, each pose adjustment mechanism 2 is used to carry and drive the corresponding jet mechanism 1; the setting position of each pose adjustment mechanism 2 at least corresponds to the position of one of all seats arranged in the cabin 3.

[0043] In the embodiment, in order to meet the individual oxygen inhalation requirements of multiple passengers in the cabin 3, the oxygen generation system is provided with a plurality of pose adjustment mechanisms 2 and a plurality of jet mechanisms 1; and the pose adjustment mechanisms 2 and the jet mechanisms 1 correspond one-to-one, each pose adjustment mechanism 2 is used to carry and drive the corresponding jet mechanism 1, so as to ensure the smooth adjustment of the pose of each jet mechanism 1. The pose adjustment mechanism 2 is arranged in the cabin 3 or on the cabin wall of the cabin 3, and the setting position of each pose adjustment mechanism 2 matches the layout of the cabin 3, such as the setting position of each pose adjustment mechanism 2 at least corresponds to the position of one of all seats arranged in the cabin 3, so as to realize accurate oxygen supply to the corresponding area of the corresponding seat through the jet mechanism 1 arranged on the corresponding pose adjustment mechanism 2, thereby meeting the oxygen inhalation requirements of the passengers on the seat and improving the oxygen inhalation experience of the passengers.

[0044] Each pose adjustment mechanism 2 independently carries and drives the corresponding jet mechanism 1, so that each jet mechanism 1 can be independently adjusted in spatial position and jet angle to adapt to the differences in seat layout and passenger body shape and posture. Through the cooperative work of the multiple pose adjustment mechanisms 2 and the multiple jet mechanisms 1, the directional jet of the oxygen-enriched gas to each seat area in the cabin 3 can be realized, thereby meeting the individual oxygen inhalation requirements of each passenger in the cabin 3.

[0045] In some embodiments, part or all of the seats in the cabin 3 have corresponding pose adjustment mechanisms 2 and jet mechanisms 1, for example, each seat in the cabin 3 has at least one corresponding jet mechanism 1, so as to ensure that the passengers can obtain a directional and comfortable oxygen supply experience (or oxygen inhalation experience) on any seat.

[0046] Another embodiment of the present application provides a vehicle comprising the above-mentioned oxygen generation system.

[0047] In this embodiment, the vehicle provides oxygen-enriched gas for the occupants in the cabin 3 by using the above-mentioned oxygen generation system to meet the oxygen inhalation needs of the occupants and improve the driving experience of the occupants. For example, the oxygen generation mechanism of the oxygen generation system is arranged on the vehicle, such as in the spare structure space of the trunk, chassis, or other spare structure space of the vehicle, to fully utilize the existing spare area of the vehicle, avoid occupying the space used by the occupants in the cabin 3, and reduce the influence of noise, vibration, airflow, and the like on the occupants in the cabin 3 during the operation of the oxygen generation mechanism. The injection mechanism 1 is arranged in the cabin 3 of the vehicle and can be used to direct the oxygen-enriched gas output by the oxygen generation mechanism to the breathing area (such as the mouth and nose cavity) of the occupants in the cabin 3 to improve the targeting and efficiency of oxygen supply. The pose adjustment mechanism 2 is arranged on the vehicle body 4 (or the structure of the vehicle body 4), such as in the side wall area or roof area of the vehicle body 4, to avoid interference with the head, limbs, and other moving spaces of the occupants, thereby improving the space utilization and driving comfort in the cabin 3; and the pose adjustment mechanism 2 is arranged in the cabin 3 and used to carry and drive the injection mechanism 1, such as to drive the injection mechanism 1 to adjust the position and angle relative to the vehicle body 4 to adjust the spatial position and directional injection direction of the injection mechanism 1 in the cabin 3, thereby facilitating the adjustment of the optimal directional injection position and angle of the injection mechanism 1 according to the breathing area (such as the mouth and nose cavity) of the occupants to flexibly direct the oxygen to the breathing area of the occupants.

[0048] In combination with FIGS. 1 to 3, Figure 1 、 Figure 4 Another embodiment of the present application provides an oxygen supply method based on the above-mentioned oxygen generation system, which includes the following steps: Step 100: In response to the oxygen supply instruction in the cabin, the calibrated position of the breathing point of the occupants in the cabin 3 is determined based on the obtained information of the occupants in the cabin 3.

[0049] The method of this embodiment is applicable to the corresponding transportation tools (such as vehicles) with the above-mentioned oxygen generation system and the cabin 3, which is used to realize the directional oxygen supply for the occupants in the cabin 3 of the corresponding transportation tools to improve the comfort and oxygen inhalation experience of the occupants.

[0050] Specifically, in step 100, when receiving a corresponding instruction (denoted as an in-cabin oxygen supply instruction) about starting in-cabin oxygen supply or turning on the oxygen generation system in the cabin 3, such as the in-cabin oxygen supply instruction initiated by the occupant or the in-cabin oxygen supply instruction automatically triggered by the transportation tool in which the cabin 3 is located based on the environmental state in the cabin 3 (for example, the in-cabin oxygen supply instruction is automatically triggered when the oxygen concentration in the cabin 3 is lower than a set threshold), the in-cabin oxygen supply process is started. In the in-cabin oxygen supply process, in order to improve the oxygen supply efficiency of the oxygen generation system, reduce the oxygen supply energy consumption of the oxygen generation system, and improve the comfort of the occupant inhaling oxygen and the driving experience, etc., first, the occupant information of the occupant in the cabin 3 is acquired; based on the acquired occupant information in the cabin 3, the spatial position (denoted as the calibration position) of the breathing point (or the breathing area, such as the area near the mouth and nose cavity) of the occupant is determined to provide a target reference for subsequent directional jet oxygen supply.

[0051] Wherein, the occupant information is information that can directly or indirectly reflect the position of the breathing point of the occupant, such as the occupant information including the pose information of the seat where the occupant is located, the position of the mouth and nose area of the occupant. When the image acquisition mechanism (such as a camera) for detecting the face area (or the mouth and nose area) of the occupant is provided in the cabin 3, the position of the mouth and nose area of the occupant can be directly acquired through the image acquisition mechanism to determine the calibration position of the breathing point of the occupant; and when the image acquisition mechanism is not provided or not enabled in the cabin 3, the calibration position of the breathing point of the occupant can be determined (or estimated) through the pose information of the seat where the occupant is located, for example, by detecting whether there is an occupant on the seat in the cabin 3, when it is detected that there is an occupant on the corresponding seat, the pose information (such as the seat backrest angle, the seat cushion height, the front and rear sliding position, etc.) of the seat is acquired, the position of the head area of the occupant is calculated based on the experience model or data table combining the pre-set height range of the occupant (such as the common height interval of adults) and the current pose information of the seat, so as to estimate the approximate spatial coordinates of the breathing point (such as the mouth and nose area) of the occupant, thereby realizing the calibration of the position of the breathing point. It is worth noting that the collection of sensitive information such as personal image and identity information in the occupant information is carried out after the consent of the occupant is obtained.

[0052] Step 200, according to the calibration position, the pose adjustment of the jet mechanism 1 of the oxygen generation system is controlled to point the oxygen output port of the jet mechanism 1 to the calibration position, and oxygen jet is performed.

[0053] Specifically, in step 200, an adjustment instruction is sent to the pose adjustment mechanism 2 in which the spraying mechanism 1 corresponding to the calibration position is located according to the calibration position obtained in step 100; the pose adjustment mechanism 2 drives the spraying mechanism 1 carried thereby to adjust the spatial position and the spraying angle according to the received instruction, at least makes the oxygen outlet of the spraying mechanism 1 face the calibration position, and controls the spraying mechanism 1 to spray oxygen at the current pose, so as to realize the directional oxygen supply of the oxygen production system to the calibration position. In this way, the oxygen (or oxygen-enriched gas) is concentratedly delivered to the mouth and nose area of the driver and passenger, rapid local oxygen enrichment is realized, the oxygen supply efficiency to the driver and passenger is improved, oxygen waste is reduced, the energy consumption of the oxygen production system is reduced, and the comfort and driving experience of the driver and passenger are improved. The oxygen spraying can be started when the oxygen supply instruction in the cabin 3 is received (corresponding to the start of the oxygen production system), or can be started when the pose adjustment of the spraying mechanism 1 is controlled to the oxygen outlet of the spraying mechanism 1 pointing to the calibration position (i.e., the spraying mechanism 1 completes the pose adjustment), or can be started according to the actual use demand, the response speed of the oxygen production system or the energy saving strategy and the like.

[0054] In summary, the method of the embodiment responds to the oxygen supply instruction in the cabin, obtains and determines the breathing point calibration position of the driver and passenger, and then controls the pose adjustment of the spraying mechanism 1, so that the oxygen outlet accurately points to the calibration position and directional spraying is performed, automatic, efficient and accurate oxygen supply to the mouth and nose area of the driver and passenger is realized, the oxygen supply efficiency is improved, the energy consumption of the oxygen production system is effectively reduced, and the comfort and driving experience of the driver and passenger are improved. In addition, the oxygen spraying time can be flexibly set, the response speed and energy saving demand of the oxygen production system are considered, and the oxygen supply demand in different use scenarios is met.

[0055] Optionally, step 200 comprises: Adjusting the output parameters of the spraying mechanism 1, and adjusting the pose of the spraying mechanism 1, so that the oxygen sprayed by the spraying mechanism 1 in the direction of the calibration position reaches the preset oxygen concentration at the calibration position.

[0056] Specifically, considering that the directional jetting of oxygen to the breathing point can cause local oxygen enrichment, and that long-term inhalation of high-concentration oxygen by the human body can cause some adverse reactions (such as oxygen poisoning, respiratory discomfort, etc.), it is necessary to strictly control the oxygen concentration at the breathing point (or the designated position) to achieve safe and effective oxygen supply, while improving the oxygen inhalation comfort and experience of the driver and passenger. In the process of directional jetting of oxygen, the main factors affecting the oxygen concentration at the breathing point include the output parameters (such as oxygen flow rate, pressure, etc.) of the jetting mechanism 1 and the distance from the jetting mechanism 1 to the breathing point (which affects the concentration decay of oxygen during spatial diffusion), therefore, in the method of the embodiment, the output parameters of the jetting mechanism 1 are adjusted, and the pose of the jetting mechanism 1 is adjusted, so that the oxygen jetted by the jetting mechanism 1 towards the designated position forms a stable region with an oxygen concentration reaching (i.e. close to or lower than) or maintaining at a preset oxygen concentration at the designated position. The preset oxygen concentration is an oxygen concentration value that can meet the normal respiratory needs of the human body and will not have adverse effects on health.

[0057] Optionally, adjusting the output parameters of the jetting mechanism 1 and adjusting the pose of the jetting mechanism 1 so that the oxygen jetted by the jetting mechanism 1 towards the designated position has a concentration reaching the preset oxygen concentration at the designated position comprises: adjusting the oxygen output port of the jetting mechanism 1 to point to the designated position, and adjusting the output parameters of the jetting mechanism 1 to a first output parameter corresponding to a first distance; wherein the first distance is the distance of the jetting mechanism 1 from the designated position, the first distance, the first output parameter and the preset oxygen concentration satisfy a preset output parameter-distance-oxygen concentration correspondence; or, adjusting the oxygen output port of the jetting mechanism 1 to point to the designated position, and adjusting the distance of the jetting mechanism 1 from the designated position to a second distance corresponding to a second output parameter; wherein the second output parameter is the current output parameter of the jetting mechanism 1, the second distance, the second output parameter and the preset oxygen concentration satisfy the output parameter-distance-oxygen concentration correspondence; or, adjusting the oxygen output port of the jetting mechanism 1 to point to the designated position, and adjusting the output parameters of the jetting mechanism 1 to a third output parameter, and adjusting the distance of the jetting mechanism 1 from the designated position to a third distance; wherein the third distance, the third output parameter and the preset oxygen concentration satisfy the output parameter-distance-oxygen concentration correspondence.

[0058] Specifically, considering that the conventional contact-type oxygen concentration measurement methods such as ultrasonic wave oxygen concentration measurement method and electrochemical oxygen concentration measurement method are difficult to actually measure the oxygen concentration content of the breathing point and are easy to interfere with the driver and passenger; and the corresponding non-contact oxygen measurement method (such as concentration inversion technology based on infrared spectrum absorption) has many interference factors, low measurement accuracy, response lag, high cost and other problems. In view of this, in the method of the embodiment, the main factors affecting the oxygen concentration of the breathing point include the output parameters of the injection mechanism 1 and the distance from the injection mechanism 1 to the breathing point. By pre-calibrating the mapping relationship between the output parameters of the injection mechanism 1, the oxygen injection distance and the oxygen concentration of the oxygen arrival position, the output parameter-relative distance-oxygen concentration correspondence relationship is obtained, which provides a reliable basis and guidance for subsequent determination of the output parameters of the injection mechanism 1 and the distance of the injection mechanism 1 relative to the calibration position under a specific oxygen concentration requirement. Among them, the concentration distribution of oxygen after spatial propagation and diffusion under different output parameters and injection distances can be obtained by constructing an experimental platform or using simulation means (such as computational fluid dynamics CFD simulation), and then a quantitative relationship between the three is established, so as to determine the output parameter-relative distance-oxygen concentration correspondence relationship; the correspondence relationship can be represented in the form of a multi-dimensional lookup table, a mathematical model or a neural network model, and can be corrected or weighted in combination with environmental variables (such as the wind speed and temperature in the cabin 3).

[0059] Based on the output parameter-relative distance-oxygen concentration correspondence relationship, the required output parameter (referred to as the first output parameter) can be determined according to the preset oxygen concentration required by the calibration position and the distance (referred to as the first distance) from the current position of the injection mechanism 1 to the calibration position, so that the oxygen output port of the injection mechanism 1 can be adjusted to point to the calibration position and the output parameter of the injection mechanism 1 can be adjusted to the first output parameter without changing the first distance, thereby achieving oxygen supply at the preset oxygen concentration at the calibration position to meet the oxygen inhalation requirement of the driver and passenger.

[0060] Alternatively, based on the output parameter-relative distance-oxygen concentration correspondence relationship, the required relative distance (referred to as the second distance) can be determined according to the preset oxygen concentration required by the calibration position and the current output parameter (referred to as the second output parameter) of the injection mechanism 1, so that the oxygen output port of the injection mechanism 1 can be adjusted to point to the calibration position and the position of the injection mechanism 1 can be adjusted to the distance from the injection mechanism 1 to the calibration position as the second distance without changing the second output parameter, thereby achieving oxygen supply at the preset oxygen concentration at the calibration position to meet the oxygen inhalation requirement of the driver and passenger.

[0061] Or, based on the output parameter-relative distance-oxygen concentration correspondence relationship, the oxygen output port pointing position of the injection mechanism 1 is adjusted, and by simultaneously adjusting the output parameter of the injection mechanism 1 and the distance of the injection mechanism 1 relative to the calibration position, the adjusted output parameter (denoted as the third output parameter) and the relative distance (denoted as the third distance) satisfy the preset output parameter-relative distance-oxygen concentration correspondence relationship, so that the oxygen is supplied at the calibration position with the preset oxygen concentration, and the oxygen absorption demand of the driver and passenger is met. For example, under the condition that the adjustment range is limited, such as the limited position adjustment range of the injection mechanism 1 and the limited output parameter adjustment range, at this time, by simultaneously adjusting the output parameter of the injection mechanism 1 and the distance of the injection mechanism 1 relative to the calibration position, the two adjustment variables are optimized, so that the injection mechanism 1 can still output the preset oxygen concentration at the calibration position within its adjustable range.

[0062] In this way, the adjustment means of the oxygen concentration control strategy is enriched, so that the oxygen generating system can flexibly select the adjustment path according to different situations, and the adaptability and robustness of the oxygen concentration adjustment process are improved. At the same time, compared with the traditional oxygen concentration detection means which depends on complex, expensive and limited precision, the mapping relationship between the output parameter, the injection distance and the oxygen concentration of the target position is established, so that high-precision oxygen supply control can be realized without real-time oxygen measurement, which has the advantages of simple structure, low cost, fast response, high adjustment precision and the like, and effectively improves the intelligent level of the oxygen generating system and the experience of the driver and passenger.

[0063] Optionally, based on the obtained driver and passenger information in the cabin 3, the calibration position of the breathing point of the driver and passenger is determined as follows: Based on the obtained pose information of the seat where the driver and passenger are located, the preset position corresponding to the pose information is determined as the calibration position of the breathing point; Or, based on the image of the mouth and nose region of the driver and passenger obtained by the image acquisition mechanism corresponding to the cabin 3, the position of the mouth and nose region of the driver and passenger is determined as the calibration position of the breathing point based on the three-dimensional coordinate system of the image acquisition mechanism.

[0064] Specifically, in determining the calibration position of the breathing point of the occupant, the calibration position of the breathing point can be determined based on the pose information of the seat where the occupant is located. For example, based on the seat-related sensors in the cabin 3, whether there is an occupant on the seat in the cabin 3 is detected, and when it is detected that there is an occupant on the corresponding seat, the pose information (such as the seatback angle, the seat cushion height, the front and rear sliding position, etc.) of the seat is obtained, so as to determine the preset position corresponding to the current pose of the seat according to the mapping relationship between the preset position and the head and nose region position of the occupant (denoted as the preset position), which can correspond to the breathing point of the occupant and can be used as the calibration position of the breathing point of the occupant. The mapping relationship can be obtained by means of ergonomic modeling, actual measurement or simulation analysis, etc. In some embodiments, the mapping relationship also needs to consider individual differences of the occupant, such as height, body shape, head size and sitting habit, etc. By collecting and analyzing the physiological parameters and posture characteristics of different occupants, a multi-dimensional mapping model containing individual parameters is established, which can realize the individualized calibration of the breathing point position (preset position) of different occupants; based on this, the individual parameters of the corresponding occupant (which can be obtained directly or indirectly; for indirect acquisition, such as by obtaining the weight of the occupant, and then inferring the height of the occupant) can be obtained by the corresponding sensors arranged in the cabin 3 (such as in the cabin), as the input of the multi-dimensional mapping model, so as to obtain a more accurate preset position, realize the dynamic accurate positioning of the breathing point of different occupants, and then guide the accurate oxygen supply of the oxygen injection mechanism 1, and improve the oxygen supply effect and comfort.

[0065] In determining the calibration position of the breathing point of the occupant, the calibration position of the breathing point can also be determined based on the image information about the mouth and nose region of the occupant in the cabin 3 obtained by the image acquisition mechanism (such as the camera arranged in the cabin 3) arranged corresponding to the cabin 3. For example, the image data of the occupant in the cabin 3 can be acquired by the camera, and the mouth and nose region of the occupant can be recognized and detected by combining the image recognition algorithm (such as face recognition and key point positioning network); further, the two-dimensional coordinates of the recognized mouth and nose region in the image plane are converted into the three-dimensional coordinates in the physical space under the three-dimensional coordinate system set based on the image acquisition mechanism, so as to determine the three-dimensional coordinates as the calibration position of the breathing point. In this way, the accuracy of obtaining the calibration position of the breathing point can be effectively improved, especially in the case that the physical features and postures of different occupants are different, the spatial position of the mouth and nose region can still be accurately recognized and mapped, thereby providing a reliable basis for subsequent adjustment of the oxygen injection direction and optimization of the oxygen supply efficiency, and further improving the intelligent level of the oxygen generation system and the comfort experience of the occupant.

[0066] Optionally, based on the image of the mouth and nose area of the driver or passenger obtained by the image acquisition mechanism arranged corresponding to the cabin 3, the calibrated position of the breathing point of the driver or passenger is determined as the position of the mouth and nose area in the three-dimensional coordinate system of the image acquisition mechanism. Based on the continuous preset number of images and the three-dimensional coordinate system constructed with the position of the image acquisition mechanism as the origin, the coordinates of the mouth and nose area of the driver or passenger in the three-dimensional coordinate system are determined as the calibrated position of the breathing point.

[0067] In determining the calibrated position of the breathing point of the driver or passenger, the spatial position of the mouth and nose area in the cabin 3 can be determined as the calibrated position of the breathing point based on the image information of the mouth and nose area of the driver or passenger obtained by the image acquisition mechanism arranged corresponding to the cabin 3, combined with the three-dimensional coordinate system of the image acquisition mechanism. Specifically, based on the three-dimensional coordinate system constructed with the position of the image acquisition mechanism as the origin, such as the optical center or mounting center of the camera of the image acquisition mechanism, combined with the preset X, Y, Z axis directions of the structure of the cabin 3 (or the corresponding transportation tool where the cabin 3 is located), a fixed reference coordinate system is formed; and according to the continuous image data of the driver or passenger face acquired by the image acquisition mechanism, a continuous preset number of image frames (such as 3 frames, 5 frames, etc.) are selected as the basis for calculation. Through image processing and recognition algorithm, such as face detection algorithm based on deep learning (such as face recognition detection algorithm based on YOLO) and three-dimensional face key point positioning network, the face area of the driver or passenger in each selected image is recognized, and the key point information of the mouth and nose area is extracted; based on the parallax information of the feature points of the mouth and nose area in multiple images and the imaging parameters (including internal and external parameters) of the image acquisition mechanism itself, the accurate spatial coordinates of the mouth and nose area in the three-dimensional coordinate system of the image acquisition mechanism can be calculated through three-dimensional reconstruction technology, and the obtained spatial coordinates can be used as the calibrated position of the breathing point to guide the subsequent directional control and position matching of the oxygen supply injection mechanism 1, thereby realizing more accurate and efficient directional oxygen supply. Among them, considering that the position of the mouth and nose area of the same driver or passenger in different image frames may differ due to slight head movement, posture change or image recognition error, in order to improve the calculation stability and calibration accuracy, the spatial coordinates of the mouth and nose area recognized in multiple images can be clustered and analyzed or weighted and averaged to obtain stable representative coordinates as the final calibrated position of the breathing point. Moreover, in order to further determine the three-dimensional coordinate position of the mouth and nose area in space, a size estimation method based on face model can be introduced for depth estimation, and the estimation steps are as follows: Image width ratio calculation: according to the known three-dimensional model of human face or the size data of average human face (such as human face height H), and the pixel height (or pixel points) h occupied by the detected human face in the image, the image width ratio s = actual height H / pixel size h is calculated, which can represent the physical size in actual space corresponding to each 1 pixel size in the image; Distance calculation: the distance d between the mouth-nose region of the passenger and the camera is calculated according to the known camera focal length f, d = camera focal length f x image width ratio s, which is the depth coordinate (Z-axis direction) of the mouth-nose region in front of the camera; Image coordinate conversion: on the basis of obtaining the distance d, the pixel coordinates of the center point of the mouth-nose region in the image , combined with the imaging intrinsic parameters (such as principal point coordinates and pixel unit focal length ) of the camera, the image coordinates can be converted into spatial coordinates by using the pinhole camera model; the conversion formula is as follows: , , ; Three-dimensional coordinate acquisition: the three components (X, Y, Z) calculated are combined, and the spatial coordinate position of the mouth-nose region in the three-dimensional coordinate system established with the camera as the origin can be obtained, which is the breathing point calibration position of the passenger.

[0068] In this way, without the aid of additional distance measuring sensors, only monocular image acquisition equipment and a standard face model can be used to estimate the depth of the mouth-nose region of the passenger and locate it in three dimensions, further improving the accuracy and real-time performance of the breathing point calibration and ensuring the efficient operation of the directional oxygen injection and the user's oxygen inhalation experience.

[0069] Optionally, the oxygen supply method further comprises: Whenever the oxygen injection lasts for a preset time length, the calibration position of the breathing point of the passenger is updated.

[0070] Specifically, considering that the passenger's pose may change during the ride, such as adjusting the backrest angle, tilting the head left and right, lowering the head, or leaning forward in the sitting position, which may cause the previously calibrated breathing point position to deviate from the actual mouth-nose region. To ensure that the oxygen is continuously and accurately injected to the actual breathing point of the passenger, a dynamic updating mechanism is provided in this embodiment. Specifically, whenever it is detected that the oxygen injection has lasted for a preset time length (such as 20 seconds or 30 seconds, etc.), a new calibration position determination process is triggered, for example, the current passenger image information is collected by the camera, and the mouth-nose region of the passenger is repositioned using image recognition algorithm, then the identified mouth-nose region is three-dimensionally reconstructed combined with the intrinsic and extrinsic parameters of the camera and the three-dimensional coordinate conversion model, and the calibration position of the breathing point in the cabin space is updated.

[0071] When the calibration position changes, at least the pose of the injection mechanism 1 is controlled to adjust the oxygen output port of the injection mechanism 1 to point to the new calibration position.

[0072] Specifically, if the new calibration position (i.e., the re-determined calibration position) changes compared to the last calibration position, it is determined that the breathing point of the occupant has changed, the pose adjustment mechanism 2 in which the jet mechanism 1 is located is controlled to adjust the pose of the jet mechanism 1, and at least the pose of the jet mechanism 1 is controlled to adjust to the oxygen outlet of the jet mechanism 1 pointing to the new calibration position, so as to achieve continuous and stable oxygen supply effect. In some embodiments, the position and output parameters of the jet mechanism 1 also need to be adjusted so that the jet mechanism 1 directs the oxygen jet towards the calibration position, and the concentration of oxygen at the new calibration position reaches the preset oxygen concentration.

[0073] Alternatively, since the oxygen supply effect of the occupant's breathing point within a certain spatial range has a tolerance, that is, as long as the oxygen outlet points to the effective oxygen supply area near the breathing point, the occupant's oxygen inhalation experience can be ensured, therefore, when the spatial offset of the breathing point position obtained by re-calibration compared to the last calibration position is lower than the preset threshold, it can be considered that the breathing point of the occupant has not changed substantially, at this time, the pose of the jet mechanism 1 does not need to be adjusted, thereby reducing the response frequency of the oxygen generation system, reducing energy consumption and prolonging the service life; if the spatial offset of the breathing point position obtained by re-calibration compared to the last calibration position is not lower than the preset threshold, it is considered that the breathing point of the occupant has changed substantially, at this time, the pose of the jet mechanism 1 needs to be adjusted accordingly to ensure effective oxygen supply. The preset threshold can be set according to the actual use scene or demand.

[0074] Alternatively, the pose adjustment mechanism 2 and the jet mechanism 1 of the oxygen generation system are provided in plurality, and the pose adjustment mechanism 2 and the jet mechanism 1 are one-to-one corresponding, each pose adjustment mechanism 2 is used to carry and drive the corresponding jet mechanism 1; the setting position of each pose adjustment mechanism 2 at least corresponds to one of all seats provided in the cabin 3, and each seat has a corresponding pose adjustment mechanism 2; When there are multiple occupants, based on the obtained occupant information in the cabin 3, determining the calibration position of the breathing point of the occupant includes: Based on the obtained occupant information of each occupant in the cabin 3, determining the calibration position of the breathing point of each occupant; According to the calibration position, controlling the pose adjustment of the jet mechanism 1 of the oxygen generation system to the oxygen outlet of the jet mechanism 1 pointing to the calibration position, and performing oxygen jetting includes: Controlling the jet mechanism 1 corresponding to each calibration position to adjust the pose to the oxygen outlet pointing to the corresponding calibration position, and respectively performing oxygen jetting.

[0075] Specifically, the pose adjustment mechanism 2 and the spraying mechanism 1 are both provided with multiple, the pose adjustment mechanism 2 and the spraying mechanism 1 one-to-one correspondence, each pose adjustment mechanism 2 for carrying and driving the corresponding spraying mechanism 1, the setting position of each pose adjustment mechanism 2 at least with the one in all seats set in the cabin 3 Corresponding, to ensure that the driver and passenger can obtain the directional, comfortable oxygen supply experience (or oxygen inhalation experience) on any seat, preferably each seat in the cabin 3 has the pose adjustment mechanism 2 and the spraying mechanism 1 corresponding to it respectively. On this basis, for the case that multiple driver and passengers exist in the cabin 3, in step 100, in response to the oxygen supply instruction in the cabin, based on the driver and passenger information of each driver and passenger in the cabin 3 obtained, the calibration position of the breathing point of each driver and passenger is determined respectively, thereby providing a target reference for subsequent directional spraying oxygen supply. In step 200, for each breathing point calibration position, the pose adjustment mechanism 2 where the corresponding oxygen spraying mechanism 1 is located is controlled respectively, so that the oxygen output port of each spraying mechanism 1 is accurately pointed to the corresponding breathing point, and oxygen spraying is carried out respectively, to provide customized oxygen supply for each driver and passenger, and ensure that each driver and passenger can inosculate and efficiently inhale oxygen.

[0076] Exemplarily, usually each seat in the cabin 3 corresponds to at most one driver and passenger, therefore, each seat can be associated with a spraying mechanism 1 and its corresponding pose adjustment mechanism 2 by default. When it is detected that a driver and passenger exists on the seat, in response to the oxygen supply instruction in the cabin, the spraying mechanism 1 corresponding to the seat can be automatically enabled, and the breathing point position of the driver and passenger is calibrated based on the relevant information (i.e. driver and passenger information) of the driver and passenger, so that the pose adjustment mechanism 2 drives the spraying mechanism 1 to accurately align with the breathing point and carries out directional oxygen supply. If no driver and passenger is detected on a seat, the corresponding spraying mechanism 1 remains closed or enters a standby state, so as to save resources and avoid unnecessary oxygen supply waste. In this way, the personalized oxygen inhalation needs of multiple people on different seats at the same time can be met.

[0077] Another embodiment of the present application provides an oxygen supply device, comprising: A position calibration module is configured to determine the calibration position of the breathing point of the driver and passenger in response to the oxygen supply instruction in the cabin based on the driver and passenger information obtained in the cabin 3. A directional spraying control module is configured to control the pose adjustment of the spraying mechanism 1 of the oxygen generating system to the oxygen output port of the spraying mechanism 1 to point to the calibration position and carry out oxygen spraying according to the calibration position.
