[0001] This utility model relates to the field of vehicle-mounted oxygen generation technology, and in particular to a vehicle-mounted mobile oxygen chamber system and vehicle. Background Technology

[0002] During driving, the oxygen concentration in the relatively sealed environment inside the car gradually decreases. Over time, this can cause driver fatigue and reduce the driver's reaction time.

[0003] Currently, when driving in high-altitude areas, people usually carry oxygen cylinders or oxygen bags for temporary oxygen supply. These temporary oxygen supply devices need to be equipped separately by the driver and passengers, which is inconvenient to use and takes up space in the cabin, affecting the comfort of driving and riding.

[0004] In some solutions, portable oxygen concentrators are used in the vehicle, typically placed inside the passenger compartment. However, these portable oxygen concentrators usually only provide individual nasal feeding for those who need it. Furthermore, they occupy interior space, their compressors are noisy, and the placement of the nitrogen exhaust outlet after oxygen separation is inconvenient, affecting passenger comfort.

[0049] like Figures 1-2 As shown, this embodiment provides a vehicle-mounted mobile oxygen chamber system, which is installed on a vehicle. The vehicle-mounted mobile oxygen chamber system includes an air compression module 2, a nitrogen-oxygen separation module 1, and an oxygen output component.

[0050] An air compressor module 2 is located under the hood of the vehicle's front compartment. The input of the air compressor module 2 is connected to the outside environment. The air compressor module 2 includes an air compressor unit 20. A nitrogen-oxygen separator module 1 is located on the floor of the vehicle's trunk. The input of the nitrogen-oxygen separator module 1 is connected to the output of the air compressor module 2. The nitrogen-oxygen separator module 1 is used to generate oxygen. An oxygen output component is located in the vehicle's passenger compartment. The input of the oxygen output component is connected to the output of the nitrogen-oxygen separator module 1. The air compressor module 2, the nitrogen-oxygen separator module 1, and the oxygen output component are all communicatively connected to the vehicle's center console 5.

[0051] like Figure 1 and Figure 2 As shown, in some embodiments, the air compression module 2 is connected to the nitrogen-oxygen separation module 1 via the first connecting pipe 7, and the nitrogen-oxygen separation module 1 is connected to the oxygen output component via the second connecting pipe 9.

[0052] The vehicle-mounted mobile oxygen chamber system provided in this embodiment has an air compression module 2 located under the hood of the vehicle's front compartment, isolated from the passenger compartment. The noise generated by the air compression module 2 (such as air compressor unit 20) has minimal impact on the passenger compartment. An oxygen output component is located within the passenger compartment, supplying oxygen to create a comfortable oxygen-rich environment. The air compression module 2 is located under the hood, the nitrogen-oxygen separation module 1 is located in the trunk, and the oxygen output component is located within the passenger compartment. The air compression module 2, nitrogen-oxygen separation module 1, and oxygen output component are strategically and separately distributed across different parts of the vehicle, minimizing their impact on the passenger compartment space. All three components are communicatively connected to the vehicle's central control panel 5. The central control panel 5 coordinates and controls these three parts, achieving coordinated oxygen production and supply while facilitating use by the driver and passengers.

[0053] like Figures 1-4 As shown, optionally, the vehicle-mounted mobile oxygen chamber system also includes an oxygen concentration sensor 6 and a flow regulating valve. The oxygen concentration sensor 6 is located inside the passenger compartment and is communicatively connected to the vehicle's center console 5. The oxygen concentration sensor 6 is used to detect the oxygen concentration inside the passenger compartment. The flow regulating valve is used to regulate the oxygen flow rate output by the nitrogen-oxygen separation module 1, and the flow regulating valve is communicatively connected to the vehicle's center console 5. Passengers can operate the center console 5 to adjust the flow regulating valve based on the oxygen concentration information output by the center console 5, thus easily adjusting the oxygen content inside the passenger compartment.

[0054] In some embodiments, the DC power module is used to supply power to the oxygen concentration sensor 6, the nitrogen-oxygen separation module 1, and the air compression module 2.

[0055] like Figure 4 and Figure 6 As shown, optionally, the nitrogen-oxygen separation module 1 includes a first molecular sieve element 15, a second molecular sieve element 18, a multi-way control valve 17, an oxygen storage tank 11, and a nitrogen discharge pipe 16. The multi-way control valve 17 is connected to the air compression module 2. The multi-way control valve 17 selectively connects to the input end of the first molecular sieve element 15 and the input end of the second molecular sieve element 18. The multi-way control valve 17 is connected to the nitrogen discharge pipe 16. The output end of the first molecular sieve element 15 and the output end of the second molecular sieve element 18 are both connected to the input end of the oxygen storage tank 11. The output end of the oxygen storage tank 11 is connected to the oxygen output component.

[0056] In some embodiments, the multi-way control valve 17 is a solenoid valve with four ports, which are respectively connected to the first molecular sieve element 15, the second molecular sieve element 18, the nitrogen discharge pipe 16, and the air compression module 2. The multi-way control valve 17 can control the opening and closing of each port individually.

[0057] In some embodiments, the first molecular sieve 15 and the second molecular sieve 18 may employ pressure swing adsorption (PSA) gas separation technology to separate oxygen and nitrogen in the air by utilizing the differences in the "adsorption" performance of molecular sieves for different gas molecules.

[0058] In some embodiments, the output end of the nitrogen venting pipe 16 extends outside the vehicle to vent nitrogen outside the vehicle and avoid affecting the oxygen concentration in the passenger compartment.

[0059] When the nitrogen-oxygen separation module 1 is working, the multi-way control valve 17 is connected to the first molecular sieve element 15 and disconnected from the second molecular sieve element 18. When the pressurized air output by the air compression module 2 enters the molecular sieve bed in the first molecular sieve element 15 through the multi-way control valve 17, nitrogen is adsorbed and oxygen is released from the output end of the first molecular sieve element 15 and flows into the oxygen storage tank 11. After the first molecular sieve element 15 is saturated with adsorption, the multi-way control valve 17 switches to connect with the second molecular sieve element 18 and the first molecular sieve element 15. Pressurized air enters the second molecular sieve element 18 through the multi-way control valve 17. At this time, the first molecular sieve element 15, which is saturated with adsorption, discharges nitrogen through the multi-way control valve 17 and the nitrogen discharge pipe 16, and resumes the process of adsorbing nitrogen and releasing oxygen in the next working cycle. The first molecular sieve element 15 and the second molecular sieve element 18 alternate with each other, and oxygen continuously enters the oxygen storage tank 11 and then enters the oxygen output component from the oxygen storage tank 11. The oxygen output component diffuses oxygen into the passenger compartment to increase the oxygen content in the vehicle for the driver and passengers to breathe, while nitrogen is discharged to the outside of the passenger compartment.

[0060] like Figure 5 and Figure 6As shown, in some embodiments, the nitrogen-oxygen separation module 1 further includes a receiving box 112. On the bottom plate inside the receiving box 112, a first molecular sieve element 15 and a second molecular sieve element 18 are arranged side-by-side at intervals along the width direction of the receiving box 112. An oxygen storage tank 11 and a multi-way control valve 17 are disposed between the first molecular sieve element 15 and the second molecular sieve element 18, and the oxygen storage tank 11 and the multi-way control valve 17 are sequentially distributed along the length direction of the receiving box 112. An air inlet connector 110 and a nitrogen vent connector 116 are provided on the side wall of the receiving box 112 near the multi-way control valve 17 along the length direction. Both the air inlet connector 110 and the nitrogen vent connector 116 are connected to the multi-way control valve 17. An oxygen outlet connector 111 is provided on the side wall of the receiving box 112 near the oxygen storage tank 11 along the length direction. This arrangement facilitates the sharing of the oxygen storage tank 11 and the multi-way control valve 17 between the first molecular sieve element 15 and the second molecular sieve element 18. Furthermore, it allows for easy connection of the air inlet connector 110, the nitrogen vent connector 116, and the multi-way control valve 17. The structure is compact and space-saving, and the air inlet connector 110, nitrogen vent connector 116, and oxygen outlet connector 111 are distinguished by their different locations. In this embodiment, the nitrogen vent pipe 16 can be connected to the nitrogen vent connector 116, and the air compression module 2 can be connected to the air inlet connector 110. In some embodiments, the housing 112 comprises a housing body with an opening at the top and a top cover, the top cover being detachably disposed at the opening at the top of the housing body.

[0061] like Figure 4 and Figure 6 As shown, in some embodiments, the output end of the oxygen storage tank 11 is equipped with a pressure regulating valve 12, a one-way valve 13, and a flow regulating valve. Specifically, a pressure regulating valve 12 is installed at the output end of the oxygen storage tank 11, and the pressure regulating valve 12 is connected to the flow regulating valve through a connecting pipe. The one-way valve 13 is installed on the connecting pipe. The one-way valve 13 prevents oxygen from flowing back into the oxygen storage tank 11, the flow regulating valve regulates the output flow rate and velocity of the oxygen storage tank 11, and the pressure regulating valve 12 regulates the pressure of the oxygen storage tank 11. Furthermore, the pressure regulating valve 12, the one-way valve 13, and the flow regulating valve are all disposed within the receiving box 112, and are all located between the multi-way control valve 17 and the oxygen storage tank 11, resulting in a compact structure.

[0062] In some embodiments, the output end of the oxygen storage tank 11 is provided with a throttle valve 19.

[0063] In some embodiments, the nitrogen exhaust pipe 16 is connected to a nitrogen exhaust muffler 8, thereby reducing exhaust noise and improving ride comfort. Specifically, the nitrogen exhaust muffler 8 extends from the floor of the trunk, through the floor, to the outside of the vehicle, thus both venting nitrogen gas to the outside of the vehicle and reducing nitrogen exhaust noise.

[0064] like Figure 7 and Figure 8As shown, in one embodiment, the air compressor unit 20 is an oil-free scroll air compressor. The air compression module 2 also includes a cooling water tank 35, a cooling water pipe 33, and a cooling water pump 36. The air compressor unit 20 is equipped with cooling water channels, and the cooling water channels and the cooling water tank 35 are connected by the cooling water pipe 33. The three together form a cooling circuit. The cooling water pump 36 is used to pump cooling water in the cooling circuit. By setting up the above cooling circuit, water cooling of the oil-free scroll air compressor is achieved, resulting in good cooling effect, long service life, and high oxygen production efficiency.

[0065] In some embodiments, the oil-free scroll air compressor is directly driven by a permanent magnet synchronous motor.

[0066] In some embodiments, the cooling water tank 35 is also equipped with a cooling fan 34, which faces the air compressor unit 20 to provide a combination of air and water cooling.

[0067] like Figure 7 and Figure 8 As shown, in some embodiments, to achieve integrated assembly of the air compression module 2, the air compression module 2 further includes a U-shaped mounting bracket 31. The U-shaped mounting bracket 31 includes a first side plate 311, a horizontal plate 312, and a second side plate 313 connected in sequence. The first side plate 311 and the second side plate 313 are arranged opposite each other at both ends of the horizontal plate 312 to form a U-shaped groove with the opening facing downwards. The water-cooled air compressor unit 20 and the cooling water tank 35 are both arranged in the U-shaped groove. The air compressor unit 20 is connected to the horizontal plate 312, and the cooling water tank 35 is connected to the first side plate 311.

[0068] like Figure 9 and Figure 10 As shown, in another embodiment, the air compression module 2 further includes a box-type mounting bracket 26, a cooling fan 27, and a compressor controller 25. The box-type mounting bracket 26 includes two opposing vented walls. The cooling fan 27 and the compressor controller 25 are respectively disposed opposite to each other on the two vented walls. The air compressor unit 20 is disposed inside the box-type mounting bracket 26, located between the cooling fan 27 and the compressor controller 25. The cooling air blown by the cooling fan 27 is directed towards the compressor unit inside the box-type mounting bracket 26 to cool the compressor unit. The airflow blowing out from the other side of the box-type mounting bracket 26 cools the compressor controller 25 before being discharged into the atmosphere. By setting the above air-cooling path, multiple components can be cooled together, improving the air-cooling utilization efficiency.

[0069] In some embodiments, the box-type mounting bracket 26 is a rectangular sheet metal structure with a door on one side.

[0070] In some embodiments, the ventilated box wall is a box wall with louvers.

[0071] In some embodiments, the compressor controller 25 is disposed on the outer wall of the vent box, and a protective cover is placed over the compressor controller 25 and fixed on the box-type mounting bracket 26, thereby protecting the compressor controller 25.

[0072] like Figures 7-10 As shown, optionally, the air compressor module 2 includes a mounting bracket and a vibration damping assembly. The mounting bracket is located under the hood of the vehicle's front compartment, and the air compressor unit 20 is connected to the mounting bracket via the vibration damping assembly. The vibration damping assembly buffers the vibration of the air compressor unit 20, reducing the noise generated by the vibration of the air compressor unit 20, thereby improving comfort. The mounting bracket can be either the U-shaped mounting bracket 31 described above or the box-shaped mounting bracket 26 described above.

[0073] In some embodiments, the mounting bracket is detachably mounted under the hood of the vehicle's front hood. For example, it is installed and secured by bolts.

[0074] like Figure 7 As shown, in some embodiments, the damping assembly includes a connecting shaft, a damping sleeve 310, and fasteners. A connecting portion is provided on the mounting bracket, and a mounting hole is provided on the connecting portion. The connecting shaft includes a main body section and a journal section. The diameter of the journal section is smaller than the diameter of the main body section. The journal section passes through the mounting hole and is connected to the fasteners. The damping sleeve 310 is provided between the journal section and the wall of the mounting hole. The main body section and the fasteners are positioned at both ends of the damping sleeve 310 in the length direction. The main body section is connected to the air compressor unit 20. The damping sleeve 310 is placed between the journal section and the wall of the mounting hole, providing elastic buffering contact between the connecting shaft and the connecting portion, achieving buffering in the radial direction of the connecting shaft. The damping sleeve 310 is placed between the main body section and the fasteners, achieving buffering in the axial direction of the connecting shaft, thereby achieving the technical effect of vibration reduction.

[0075] In some embodiments, the air compressor unit 20 is provided with a through hole, through which the main body section of the connecting shaft passes and is connected with a bolt, thereby connecting the air compressor unit 20 to the connecting shaft.

[0076] In some embodiments, multiple connecting shafts, damping sleeves 310, and fasteners are provided in a one-to-one correspondence. Some connecting shafts extend vertically, and the mounting bracket has vertically open mounting holes. Some connecting shafts extend horizontally, and the mounting bracket also has horizontally open mounting holes. The vertical and horizontal connecting shafts achieve a fixed connection between the air compressor unit 20 and the mounting bracket in three dimensions. The air compressor unit 20 is connected in all three dimensions, the connection is stable, and it has a vibration damping effect in all three dimensions.

[0077] like Figure 7As shown, exemplarily, the shock-absorbing component can be used on a U-shaped mounting bracket 31. The horizontal plate 312 of the U-shaped mounting bracket 31 has multiple connecting parts, and connecting shafts in three directions are suspended and connected to the horizontal plate 312 through these connecting parts. Specifically, there are three connecting shafts: a suspension pull shaft 37, a cantilever shaft 38, and a transverse shaft 39. The lower end of the suspension pull shaft 37 passes through a through hole in the air compressor unit 20 and is secured with a nut. The journal section at the upper end of the suspension pull shaft 37 passes through a mounting hole in the horizontal plate 312 and is tightened with a nut. Similarly, the journal section at the left end of the cantilever shaft 38 passes through a through hole in the air compressor unit 20 and is secured with a nut. The journal section at the right end of the cantilever shaft 38 passes through a mounting hole in a downwardly protruding ear plate of the horizontal plate 312 and is tightened with a nut. The transverse shaft 39 passes through the through hole on the air compressor unit 20. The journal sections at both ends of the transverse shaft 39 pass through the mounting holes on the second ear plate protruding downward from the horizontal plate 312 and are tightened with nuts. Above, shock-absorbing sleeves 310 are placed between the journal sections of the suspension shaft 37, the cantilever shaft 38 and the transverse shaft 39 and the corresponding mounting holes. Thus, the compressor unit is elastically suspended in the U-shaped mounting bracket 31 through three connecting shafts.

[0078] like Figure 10 As shown, in other embodiments, the damping assembly may further include multiple elastic dampers 28, which include springs or rubber. The air compressor unit 20 is flexibly connected to the mounting frame via multiple elastic dampers 28, thereby achieving a damping effect.

[0079] like Figure 10 As shown, in some embodiments, the damping assembly can be used on the box-type mounting bracket 26. Four elastic dampers 28 are spaced apart on the bottom wall of the air compressor unit 20, and the four elastic dampers 28 are disposed on the bottom plate of the box-type mounting bracket 26, thereby achieving an elastic connection of the air compressor unit 20 within the box-type mounting bracket 26.

[0080] like Figure 7 and Figure 10 As shown, in some embodiments, the air compression module 2 further includes an intake filter 21, which is connected to the input terminal of the air compressor unit 20. The intake filter 21 filters the air entering the air compressor unit 20, ensuring the cleanliness of the interior of the air compressor unit 20 and improving its service life.

[0085] In some embodiments, the plug 44 is connected to the nozzle seat 42 via a hinge shaft 46, thereby opening or closing the groove in a flip-over manner.

[0086] In some embodiments, the plug 44 is provided with a plug 45. When the plug 44 closes the groove, the plug 45 blocks the outlet of the nozzle 43, which is beneficial to protect the nozzle 43 and improves the aesthetics of the oxygen supply nozzle 4.

[0087] The vehicle-mounted mobile oxygen chamber system provided in this embodiment has an air compression module 2 located under the hood of the vehicle's front compartment, a nitrogen-oxygen separation module 1 located in the vehicle's trunk, and oxygen distribution nozzles arranged on the ceiling of the passenger compartment. The vehicle-mounted mobile oxygen chamber system is integrated into the vehicle. It is rationally arranged, produces low noise, and provides oxygen supply to the passenger compartment.

[0088] like Figure 1As shown, this embodiment also provides a vehicle, which includes a main body and the aforementioned vehicle-mounted mobile oxygen chamber system, which is mounted on the main body. The air compression module 2 is located under the hood of the vehicle's front compartment, isolated from the passenger compartment, minimizing the noise impact on the passenger compartment. An oxygen output component is located within the passenger compartment, supplying oxygen to create a comfortable oxygen-rich environment. The air compression module 2 is located under the hood, the nitrogen-oxygen separation module 1 is located in the trunk, and the oxygen output component is located within the passenger compartment. The air compression module 2, nitrogen-oxygen separation module 1, and oxygen output component are strategically and separately distributed across different parts of the vehicle, reducing their impact on the passenger compartment space. All three components are communicatively connected to the vehicle's central control panel 5. The central control panel 5 coordinates and controls these three components, achieving coordinated oxygen production and supply while facilitating use by the driver and passengers.

[0089] In some embodiments, the vehicle's center console 5 can be a vehicle center screen.
