Description

Technical Field

[0001] This invention belongs to the field of automotive technology, specifically relating to an on-board oxygen supply device and method, and a vehicle. Background Technology

[0002] With socio-economic development, automobiles have gradually transformed from traditional transportation tools into multifunctional consumer goods, with ever-evolving designs and rich features continuously challenging people's traditional perceptions of cars. Consumers' demands for automobiles are no longer limited to basic transportation; after meeting intelligent needs such as internet connectivity and smart home integration, healthy travel has become a new core requirement, making the research and application of in-vehicle health systems a crucial development direction for the automotive industry. Among these, intelligent oxygen chamber systems, as an important component of in-vehicle health equipment, can provide health protection for drivers and passengers in scenarios such as high-altitude travel and emergency oxygen therapy, and have broad application prospects.

[0003] Currently, it is feasible to equip various mainstream vehicles, including gasoline-powered vehicles, hybrid gasoline-powered vehicles, and electric vehicles, with intelligent oxygen chamber systems. However, these systems are not yet widely adopted, with only a small number of models featuring them. Existing technologies related to in-vehicle intelligent oxygen chambers still have many shortcomings. Their structural design and user experience fail to fully meet the core needs of consumers, leaving room for technological optimization.

[0004] Specifically, existing in-vehicle oxygen supply devices generally suffer from unreasonable structural layouts, making it difficult to effectively control interfering noises generated during operation. This, in turn, affects the comfort of drivers and passengers, failing to fully meet consumers' demands for in-vehicle health equipment that combines practicality and comfort. Therefore, optimizing the overall structural layout of in-vehicle oxygen supply devices to effectively reduce operational interference and improve the driving experience while stably achieving oxygen production and ensuring the health needs of drivers and passengers has become a pressing technical problem to be solved in the current research and development of in-vehicle intelligent oxygen chamber systems. Summary of the Invention

[0005] To address some or all of the aforementioned technical problems in the prior art, this invention proposes an on-board oxygen supply device and method, as well as a vehicle. This on-board oxygen supply device suspends an air compressor on the vehicle floor, achieves air separation and oxygen production through an oxygen chamber molecular sieve assembly, and delivers the oxygen to the vehicle's interior cavity via a first oxygen delivery pipe. Its rational structural layout not only stably achieves oxygen production and supply functions, ensuring the health needs of drivers and passengers, but also effectively reduces equipment operational interference and improves driving comfort.

[0006] According to a first aspect of the present invention, an on-board oxygen supply device is provided, comprising:

[0007] An air compressor, which is mounted on the floor of the vehicle and is used to filter and compress air. An oxygen chamber molecular sieve assembly, connected to the air compressor, is used to receive compressed air and perform gas separation to produce oxygen. The first oxygen supply pipe has its inlet end connected to the oxygen outlet of the oxygen chamber molecular sieve assembly, and its outlet end connected to the interior cavity of the vehicle.

[0008] In one embodiment, a mounting plate is fixed to the air compressor for hoisting onto the vehicle floor, and a vibration damping element is provided on the mounting plate for positioning between the mounting plate and the vehicle floor.

[0009] In one embodiment, the first oxygen delivery pipeline includes: The first main oxygen supply pipeline section used to connect the oxygen outlet of the oxygen chamber molecular sieve assembly. The first oxygen supply branch pipeline is used to connect the first oxygen supply main pipeline section. The first oxygen supply branch pipeline section includes one or more of the following: left top air duct, right top air duct, left bottom air duct, and right bottom air duct.

[0010] In one embodiment, the first oxygen delivery pipe section is configured as the air outlet pipe of a vehicle's air conditioning system.

[0011] In one embodiment, a second oxygen delivery pipe is further included, the inlet end of which is connected to the oxygen outlet of the oxygen chamber molecular sieve assembly, and the outlet end of which is disposed on the vehicle's sub-dashboard and used to connect to an oxygen supply nasal cannula.

[0012] In one embodiment, an oxygen concentration sensor is also included for measuring the oxygen concentration in the vehicle's interior cavity.

[0013] In one embodiment, the oxygen chamber molecular sieve assembly is disposed inside the vehicle's trunk and laid flat on the trunk floor.

[0014] According to a second aspect of the present invention, a vehicle is provided, comprising: Vehicle body, In the aforementioned vehicle-mounted oxygen supply device, the air compressor is mounted on the floor of the vehicle body, and the oxygen chamber molecular sieve assembly is fixed to the vehicle body.

[0015] In one embodiment, the system further includes a controller and an air conditioner. The controller is connected to the air compressor, the oxygen chamber molecular sieve assembly, the air conditioner, and the oxygen concentration sensor of the vehicle-mounted oxygen supply device. The controller is configured to acquire the current status information of the vehicle and, based on the current status information, control the air compressor to acquire air from the outside and control the oxygen chamber molecular sieve assembly to generate oxygen using the air from the air compressor, thereby controlling the oxygen concentration in the vehicle's interior. The current status information includes the vehicle's current location information and the oxygen concentration information in the vehicle's interior.

[0016] According to a third aspect of the present invention, an on-board oxygen supply method is provided for the aforementioned vehicle, comprising: Obtain the current status information of the vehicle, including the vehicle's current location information and the oxygen concentration information in the vehicle's interior cabin. Based on the current status information, the air compressor obtains air from the outside, and the oxygen chamber molecular sieve assembly uses the air from the air compressor to generate oxygen.

[0017] Compared with the prior art, the advantages of this invention are as follows: During operation, an air compressor suspended on the vehicle floor first filters and compresses the external air, and then delivers the compressed air to the oxygen chamber molecular sieve assembly connected thereafter. This oxygen chamber molecular sieve assembly uses molecular sieve adsorption technology to separate the compressed air, extract high-concentration oxygen and store it or output it directly. Finally, the oxygen is delivered directly to the vehicle cavity through the first oxygen delivery pipe, providing continuous and reliable oxygen supply for the driver and passengers. In this application, the core component, the air compressor, is located under the floor, effectively isolating operating noise and vibration from the source, greatly improving the quiet environment of the passenger compartment, solving the noise interference problem of traditional equipment, and the overall structure of the vehicle oxygen supply device is compact and rationally laid out. It not only ensures the process stability and oxygen supply efficiency of air separation oxygen production, but also facilitates installation and subsequent maintenance inside the vehicle, significantly improving the intelligence level and ride comfort of the entire vehicle, and combining practicality and advancement.

This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] like Figures 1 to 5As shown, the on-board oxygen supply device includes an air compressor 110, an oxygen chamber molecular sieve assembly 120, and a first oxygen delivery pipe 130. After installation, the air compressor 110 is suspended from the vehicle floor 210 and located outside the passenger compartment. The air compressor 110 integrates an air filter module and a compression module. The filter module intercepts impurities, dust, and other pollutants in the air, while the compression module compresses the filtered air to a preset pressure, providing a suitable air source for subsequent oxygen production. The input end of the oxygen chamber molecular sieve assembly 120 is fixedly connected to the output end of the air compressor 110 via a sealed pipe, receiving clean compressed air from the air compressor 110. It contains a dedicated molecular sieve adsorption material for efficient separation of nitrogen and oxygen. The separated oxygen is delivered to the passenger compartment, while the separated nitrogen is discharged through an exhaust pipe 121, the outlet of which is located outside the passenger compartment. The inlet end of the first oxygen delivery pipe 130 is sealed and connected to the oxygen outlet of the oxygen chamber molecular sieve assembly 120, and the outlet end extends into the vehicle cavity.

[0025] During operation, the air compressor 110 starts, filters and compresses outside air, and delivers the compressed air to the oxygen chamber molecular sieve assembly 120. The molecular sieve adsorbs and separates high-concentration oxygen, which is then delivered to the vehicle's interior through the first oxygen delivery pipe 130 to meet the oxygen needs of the occupants. In this design, the air compressor 110 is suspended from the vehicle floor 210, effectively isolating operating noise and vibration, improving the quietness of the ride. The sealed connections and reasonable layout of all components ensure stable and reliable oxygen production and supply, while also facilitating installation and maintenance, balancing practicality and comfort, and making it suitable for various vehicle models.

[0026] In one embodiment, a mounting plate 111 is fixed to the air compressor 110. The mounting plate 111 itself can be constructed as a plate-like structure. After installation, the mounting plate 111 is suspended to the vehicle floor 210, and the air compressor 110 is suspended to the mounting plate 111, thereby fixing the air compressor 110 to the vehicle. A vibration damping element 112 is provided on the mounting plate 111. After installation, the vibration damping element 112 is located between the mounting plate 111 and the vehicle floor 210, thereby achieving vibration reduction and noise reduction effects. For example, the vibration damping element 112 can be a rubber vibration damping pad. The air compressor 110 can be easily suspended to the vehicle floor 210 via the plate-like mounting plate 111, and the vibration damping element 112 on the mounting plate 111 can effectively buffer vibration and reduce noise, further improving the quietness of the ride and the stability of the device operation.

[0027] The first oxygen delivery pipeline 130 includes a first main oxygen delivery pipeline section 131 and a first branch oxygen delivery pipeline section 132. The first main oxygen delivery pipeline section 131 connects to the oxygen outlet of the oxygen chamber molecular sieve assembly 120. The first branch oxygen delivery pipeline section 132 connects to the first main oxygen delivery pipeline section 131 and delivers oxygen to the vehicle's interior. According to this application, the first branch oxygen delivery pipeline section 132 may include one or more of the following: a left top air duct 133, a right top air duct 135, a left bottom air duct 136, and a right bottom air duct 137. The first main oxygen delivery pipeline section 131 stably connects to the oxygen chamber molecular sieve assembly 120. The first branch oxygen delivery pipeline section 132 can be configured with a multi-duct structure, which helps to achieve uniform oxygen delivery within the vehicle's interior, adapts to the needs of different driving and riding areas, improves the convenience and comfort of oxygen supply, and optimizes the pipeline layout for easier installation and maintenance.

[0028] In one embodiment, the first oxygen supply branch pipe section 132 is configured as the air outlet duct of the vehicle's air conditioning system. The first oxygen supply branch pipe section 132 is directly configured as the vehicle's air conditioning outlet duct. Oxygen generated by the oxygen chamber molecular sieve assembly 120 is transported to this air conditioning outlet duct via the first main oxygen supply pipe section 131. Utilizing the air conditioning system's own blowing function, the oxygen is blown into the vehicle's interior along with the airflow. This configuration fully utilizes the vehicle's existing air conditioning ducts, eliminating the need for additional dedicated oxygen supply ducts, simplifying the structure, reducing installation costs and space occupation. Simultaneously, relying on the air conditioning's blowing function achieves rapid and uniform oxygen diffusion, significantly improving oxygen supply efficiency and allowing passengers to quickly obtain sufficient oxygen, further enhancing user comfort and the device's practicality.

[0029] In one specific configuration, the vehicle has a rear air conditioning assembly 220. This assembly contains four air vents arranged in parallel: a left overhead air vent 221, a right overhead air vent 222, a left bottom air vent 223, and a right bottom air vent 224. The air outlet of the left overhead air vent 221 is located on the left side of the vehicle's roof and within the front compartment; the right overhead air vent 222 is located on the right side of the vehicle's roof and within the front compartment; the air outlet of the left bottom air vent 223 is located on the left side of the vehicle's bottom and within the rear seats; and the air outlet of the right bottom air vent 224 is located on the right side of the vehicle's bottom and within the rear seats. This configuration allows for the parallel operation of multiple air ducts, corresponding to the multi-duct delivery of air from the left overhead vent 133, right overhead vent 135, left bottom air vent 136, and right bottom air vent 137. Oxygen is delivered via the first main oxygen supply pipe section 131 to the air outlet pipes of each parallel air duct of the rear air conditioning assembly 220. Utilizing the rear air conditioning's blowing function, oxygen is then delivered to the front cabin and rear seat areas through the corresponding air outlets. This setup utilizes the existing parallel air duct layout of the rear air conditioning system to achieve precise oxygen supply to multiple areas, catering to the needs of both front and rear cabin occupants. Oxygen diffusion is more uniform, and no additional air ducts are required, simplifying the structure, reducing costs, and improving the device's adaptability and practicality. It is easy to understand that if the vehicle's air conditioning structure is adjusted, the structure of the first oxygen supply pipe 130 can also be adjusted accordingly.

[0030] The vehicle-mounted oxygen supply device also includes a second oxygen delivery pipe 140. The inlet end of the second oxygen delivery pipe 140 is connected to the oxygen outlet of the oxygen chamber molecular sieve assembly 120, and the outlet end of the second oxygen delivery pipe 140 is located on the vehicle's sub-dashboard 230 and used to connect to the oxygen supply nasal cannula 150. During operation, a portion of the oxygen generated by the oxygen chamber molecular sieve assembly 120 is delivered through the second oxygen delivery pipe 140. Its inlet end is connected to the oxygen chamber molecular sieve assembly 120, and its outlet end extends to the sub-dashboard 230 area, where it can be connected to the oxygen supply nasal cannula 150 for direct use by the driver and passengers. By adding the second oxygen delivery pipe 140 and the oxygen supply nasal cannula 150, a dual mode of centralized diffusion oxygen supply and personalized precise oxygen supply is achieved, adapting to personalized needs such as emergency oxygen inhalation. The structure is simple and easy to use, further improving the device's applicability.

[0031] The vehicle-mounted oxygen supply system also includes an oxygen concentration sensor 160 for measuring the oxygen concentration in the vehicle's interior. This oxygen concentration sensor 160 can be fixed to the sub-dashboard 230. The oxygen concentration sensor 160 can detect the oxygen concentration in the vehicle's interior in real time, providing accurate feedback on the oxygen content within the cabin. By installing the oxygen concentration sensor 160, the oxygen supply effect can be monitored in real time, preventing excessively high or low oxygen concentrations from affecting the health of drivers and passengers. It also provides data support for the operation and adjustment of the vehicle-mounted oxygen supply system, achieving intelligent and precise oxygen supply, improving the safety and reliability of the system's operation, and adapting to various driving and passenger scenarios.

[0032] After installation, the oxygen chamber molecular sieve assembly 120 is placed inside the vehicle's trunk 240 and laid flat on the trunk 240 floor. This layout minimizes space occupation and operational interference in the passenger compartment. Simultaneously, the relatively enclosed environment of the trunk 240 effectively protects the oxygen chamber molecular sieve assembly 120, preventing external impurities and moisture from affecting oxygen purity and ensuring oxygen production quality. Furthermore, the flat placement facilitates installation and maintenance, enhancing the overall practicality and stability of the device.

[0033] This application also relates to a vehicle. The vehicle includes a vehicle body and the aforementioned on-board oxygen supply device. After connection, the air compressor 110 is mounted on the floor 210 of the vehicle body. Depending on the vehicle model or structure, the specific position of the air compressor 110 can be adjusted on the floor 210. For example, for range-extended vehicles, the air compressor 110 can be located on the load-bearing beam between the battery area and the fuel tank area in the longitudinal direction of the vehicle; while for pure electric vehicles, the installation position of the air compressor 110 should avoid the battery area. The oxygen chamber molecular sieve assembly 120 is fixed to the floor of the trunk 240 of the vehicle body. The air compressor 110 and the oxygen chamber molecular sieve assembly 120 are connected via an air delivery pipe 170. Most of this air delivery pipe 170 is confined to the vehicle floor 210. In the first oxygen delivery pipe 130, oxygen is delivered via the first main oxygen delivery pipe section 131 to each parallel air duct of the air conditioning assembly 220. Using the air conditioning blowing function, oxygen is delivered to the front cabin and rear seat areas through the corresponding air duct outlets. In the second oxygen supply pipeline 140, a portion of the oxygen generated by the oxygen chamber molecular sieve assembly 120 is transported through the second oxygen supply pipeline 140. Its inlet end is connected to the oxygen chamber molecular sieve assembly 120, and its outlet end extends to the sub-instrument panel 230, which can be connected to the oxygen supply nasal cannula 150 for direct use by drivers and passengers.

[0034] The vehicle also includes a controller (not shown) and an air conditioner 220. The controller establishes stable connections with the air compressor 110, the oxygen chamber molecular sieve assembly 120, the air conditioner 220, and the oxygen concentration sensor 160 of the on-board oxygen supply device, forming a complete intelligent control system. The core function of the controller is to acquire the vehicle's current status information in real time. This information specifically includes the vehicle's current location information and the oxygen concentration information in the cabin. After analyzing and processing the two types of information, the controller precisely controls the air compressor 110 to draw air from the outside and complete the filtration and compression. At the same time, it controls the oxygen chamber molecular sieve assembly 120 to separate the compressed air to produce high-concentration oxygen, which is then delivered to the cabin through oxygen pipelines, thereby achieving dynamic regulation of the oxygen concentration in the cabin. The centralized linkage control of this device makes the oxygen supply process more intelligent and precise. It can automatically adapt the oxygen supply parameters according to the location information (such as altitude) and real-time oxygen concentration without manual intervention. The coordinated work of each component ensures the stability of oxygen production and supply, and can avoid abnormal oxygen concentration through precise regulation, thus protecting the health of drivers and passengers. At the same time, the linkage with the air conditioning can optimize the oxygen diffusion efficiency, further improving the practicality of the device and the comfort of driving, and adapting to various driving scenarios.

[0035] This application also relates to an on-board oxygen supply method. During vehicle operation, the oxygen concentration sensor 160 monitors the oxygen concentration in the cabin in real time, while the vehicle simultaneously monitors its own location information to determine its altitude. When the oxygen concentration in the cabin is detected to be lower than or equal to the lower preset value, the controller automatically triggers the oxygen supply mode. First, the windows are closed to prevent the entry of low-oxygen or impurity air from the outside. Then, the air compressor 110, the oxygen chamber molecular sieve assembly 120, and the air conditioner 220 are started. Oxygen is supplied to the cabin simultaneously through the first oxygen delivery pipe 130 (relying on the air conditioning duct or a dedicated duct) and the second oxygen delivery pipe 140 (connected to a nasal cannula). Until the oxygen concentration in the cabin reaches or exceeds the upper preset value, the controller shuts down the air compressor 110 and the oxygen chamber molecular sieve assembly 120. The air conditioner 220 can be turned off or continued to operate according to the driving and riding needs.

[0036] It should be noted that the lower and upper preset values ​​can be adjusted based on customer experience and different setting modes. Additionally, based on vehicle location information, such as altitude, the lower and upper preset values ​​can be adjusted at different altitudes. While this application does not provide specific lower and upper preset values, it is easily understood that the oxygen concentration between these two values ​​is the oxygen concentration that ensures the comfort and health of the occupants.

[0037] This method enables automated oxygen supply control, dynamically adjusting preset values ​​based on location information (altitude) and oxygen concentration to adapt to different driving scenarios (such as plateaus and plains). The upper and lower limit preset values ​​can be flexibly adjusted according to customer experience and setting modes, taking into account both personalized needs and health protection. The dual oxygen supply pipelines, combined with the window closing design, ensure both oxygen supply efficiency and purity, while also improving driving comfort, further enhancing the intelligence and practicality of the device.
