[0003] Traditional car cabin oxygen supply methods mostly rely on on-board oxygen cylinders or oxygen concentrators. Although these devices can provide a certain amount of oxygen supply, they often have problems such as large size, high maintenance costs, and varying oxygen purity. They can only increase the oxygen concentration in the cabin but cannot reduce the carbon dioxide concentration in the cabin. In addition, for the air pressure massage function, traditional designs usually use an independent compressed air system, which not only increases the weight and complexity of the vehicle, but may also cause inconvenience in use due to incompatibility between systems.

[0004] In order to solve the above problems, the market is in urgent need of a multifunctional automotive cabin air supply system. The system should be able to efficiently separate oxygen from the air to ensure sufficient oxygen supply in the cabin, reduce the carbon dioxide concentration in the cabin, and use compressed air to perform air pressure massage at the same time, providing a full range of comfort for the driver and passengers. However, most of the existing technical solutions fail to balance the oxygen supply efficiency, massage effect, and the overall performance and cost of the system.

[0006] Therefore, developing a multifunctional air supply system for a vehicle cabin has become a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0037] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0038] Embodiment 1:

[0039] like Figure 1-Figure 8 As shown, this embodiment provides a multifunctional air supply system for a car cabin, which is intended to meet the needs of oxygen supply, carbon dioxide concentration reduction and air pressure massage in the car cabin. The multifunctional air supply system for a car cabin proposed in this application includes a control module 1, an air compressor 2, an oxygen supply unit 3, a massage unit 4 and a carbon dioxide reduction unit 6.

[0040] As the core of the whole system, the control module 1 is responsible for receiving the signals from the oxygen concentration detection device and the carbon dioxide concentration detection device, and controls the air path switching between the air compressor 2 and each unit according to the oxygen supply demand, carbon dioxide concentration and massage demand in the cabin, and is responsible for controlling the operating status of each unit to ensure the stability and efficiency of the system. The control module 1 can use intelligent control devices such as microprocessors and single-chip microcomputers to realize automatic control of the system through preset programs and algorithms.

[0041] The air compressor 2 is configured to output compressed air to provide compressed air to the oxygen supply unit 3 and the massage unit 4. A filter device 7 is connected to the air inlet of the air compressor 2 to filter impurities in the air. The air compressor 2 can be selected according to actual needs.

[0042] like Figure 1 or Figure 2 or Figure 6As shown, the oxygen supply unit 3 is connected to the air compressor 2 to obtain compressed air, and separates the oxygen in the compressed air through the oxygen separation module 31, stores it in the oxygen storage tank 32, and finally supplies it to the passengers in the cabin through the oxygen supply terminal 33. The oxygen supply terminal 33 is configured at the headrest of the car seat. The oxygen supply terminal 33 releases oxygen by detecting the human breathing frequency, so that passengers can directly inhale oxygen during the ride. When the oxygen concentration detection device detects that the oxygen concentration in the cabin is lower than the preset value, it sends a detection signal to the control module 1. The control module 1 receives the signal and sends an oxygen supply instruction to the oxygen supply unit 3, so that the oxygen supply unit 3 starts working to increase the oxygen concentration in the cabin.

[0043] At this time, the air compressor 2 compresses the inhaled air and transmits it to the oxygen separation module 31 through the first reversing valve 5. The oxygen separation module separates the oxygen and other gases in the compressed air to obtain a higher concentration of oxygen. The oxygen separation module 31 can adopt high-efficiency separation technologies such as molecular sieve components to ensure the purity and quality of the oxygen supply, store the separated oxygen in the oxygen storage tank 32, and release the oxygen into the cabin through the oxygen supply terminal 33. A pressure sensor is provided in the oxygen storage tank 32. When the pressure in the oxygen storage tank 32 reaches the preset value, the control module 1 controls the oxygen supply unit 3 to stop oxygen production, and transmits the compressed air of the air compressor 2 to the massage unit 4 through the first reversing valve 5.

[0044] like Figure 1 or Figure 3 or Figure 7 As shown, the massage unit 4 is connected to the air compressor 2 to obtain compressed air, and the compressed air is stored in the massage air tank 41, and the air pressure massage is performed on the passenger through the massage air bag 42. The massage air bag 42 is arranged at the backrest of the car seat, covering the back of the passenger, and providing a comfortable air pressure massage experience. The massage unit 4 also includes an exhaust pipe 43 connecting the massage air bag 42 and the air inlet of the air compressor 2, so as to quickly exhaust the massage air bag 42 by the suction effect of the air compressor 2. There is only one exhaust pipe 43, so as to form a negative pressure on the exhaust pipe 43, so that all the air in the massage air bag 42 can be discharged, thereby enhancing the dynamic effect and comfort of the massage.

[0045] In addition, a first reversing valve 5 for switching the air path is arranged between the oxygen supply unit 3, the massage unit 4 and the air compressor 2. The first reversing valve 5 is arranged to selectively deliver compressed air to the oxygen supply unit 3 or the massage unit 4, so as to realize flexible switching and efficient operation of the system. The first reversing valve 5 can adopt different types of valves such as solenoid valves and pneumatic valves, which can be selected according to actual needs.

[0046] like Figure 1 or Figure 4 or Figure 8As shown, the carbon dioxide reduction unit 6 is configured to transport the air in the car cabin to the air compressor 2 and discharge it into the cabin through the molecular sieve assembly 310 to reduce the carbon dioxide concentration in the cabin. The carbon dioxide reduction unit 6 includes a cabin return pipe 61 and a second reversing valve 62. The cabin return pipe 61 is connected to the car cabin and is connected to the air inlet of the air compressor 2 via the second reversing valve 62. The second reversing valve 62 is configured to selectively control the air compressor 2 to connect to the cabin return pipe 61 to extract air from the cabin or to extract air from outside the cabin, thereby realizing the circulation of air in the cabin and the introduction of fresh air from the outside.

[0047] The control module 1 is further configured to control the air path switching between the air compressor 2 and each unit according to the oxygen supply, carbon dioxide concentration and massage demand in the cabin. The control module 1 intelligently controls the operation status of each unit by monitoring the oxygen concentration and carbon dioxide concentration in the cabin in real time, as well as the massage demand of the passengers. In order to achieve this function, an oxygen concentration detection device and a carbon dioxide concentration detection device are configured in the cabin to monitor the oxygen and carbon dioxide concentrations in the cabin in real time and feed the data back to the control module 1. When it is detected that the oxygen concentration in the cabin is lower than the preset value, the control module 1 controls the air compressor 2 to deliver compressed air to the oxygen supply unit 3, and the oxygen supply unit 3 separates the oxygen and other gases in the compressed air and stores the oxygen in the oxygen storage tank 32. A pressure sensor is provided in the oxygen storage tank 32. When the pressure in the oxygen storage tank 32 reaches the preset value, the control module 1 controls the compressor 2 and the first reversing valve 5 to deliver the compressed air to the massage unit 4. If it is detected that the carbon dioxide concentration in the cabin is higher than a preset value, the control module 1 will control the carbon dioxide reduction unit 6 to transport the air in the cabin to the air compressor 2 for processing, and discharge the compressed air outside the cabin through the molecular sieve assembly 310.

[0048] In the present application, when the carbon dioxide reduction unit 6 is started, the second reversing valve 62 can only deliver the cabin air from the cabin return pipe 61 to the air compressor 2. When the carbon dioxide concentration in the cabin is reduced to a preset value, the second reversing valve 62 switches the air path connected to the cabin return pipe 62 and can only deliver the air outside the cabin to the air compressor 2.

[0049] In the embodiment, the molecular sieve assembly of the oxygen separation module 31 adopts high-efficiency separation technology, which can efficiently separate oxygen from other gases in the compressed air, and discharge the separated other gases out of the cabin, thereby avoiding the influence of other gases on the air quality in the cabin. At the same time, the massage air bag 42 of the massage unit 4 is made of soft and breathable material to ensure the comfort and safety of the massage.

[0050] Its working principle is as follows:

[0051] When a passenger needs to breathe oxygen, the control module 1 determines whether the oxygen concentration in the cabin is sufficient based on the data from the oxygen concentration detection device. If the oxygen concentration is insufficient, the control module 1 controls the air compressor 2 to work and delivers compressed air to the oxygen supply unit 3 through the first reversing valve 5. The oxygen separation module 31 separates oxygen from the compressed air and stores it in the oxygen storage tank 32. The oxygen supply terminal 33 releases oxygen by detecting the passenger's breathing rate.

[0052] When the passenger needs a massage, the control module 1 controls the air compressor 2 to work according to the massage demand, and delivers the compressed air to the massage unit 4 through the first reversing valve 5. The massage air tank 41 stores the compressed air and delivers the compressed air to the massage air bag 42 through the pipeline. The massage air bag 42 performs air pressure massage on the passenger's back according to the preset program and algorithm.

[0053] When the carbon dioxide concentration in the cabin is too high, the control module 1 determines whether the carbon dioxide concentration needs to be reduced based on the data from the carbon dioxide concentration detection device. If the carbon dioxide concentration needs to be reduced, the control module 1 controls the second reversing valve 62 to switch the air path so that the air compressor 2 extracts the air inside the cabin through the cabin return pipe 61 for processing. At the same time, the control module 1 can adjust the working state of the air compressor 2 to increase the amount of air extracted from the cabin, thereby effectively reducing the carbon dioxide concentration in the cabin.

[0054] The control module 1 can also make intelligent adjustments according to the actual situation in the cabin. For example, when the oxygen concentration and carbon dioxide concentration in the cabin need to be adjusted at the same time, the control module 1 can give priority to meeting the demand for oxygen supply; when the passenger needs a massage while breathing oxygen, the control module 1 can coordinate the working status of the oxygen supply unit 3 and the massage unit 4 to ensure that both can operate normally at the same time.

[0055] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
