[0035] The heat dissipation assembly 40 includes a radiator 41 and a fan 42. The radiator 41 is vertically mounted on top of the base plate 11 and located to one side of the intake filter 20. An air inlet and an air outlet are provided on the top of the radiator 41.

As an example, the structure of the radiator 41 is similar to that of a water-cooled radiator, and will not be described in detail here.

[0036] The solenoid valve assembly 50 is installed on top of the molecular sieve assembly 60, which is mounted on the base plate 11 and located on the other side of the intake filter 20.

[0037] The molecular sieve assembly 60 includes at least two molecular sieve towers. These towers adsorb nitrogen from compressed air and release high-purity oxygen. Each molecular sieve tower has an air inlet, a nitrogen outlet, and an oxygen outlet at its top. The air inlet and nitrogen outlet are located on the top surface of their respective towers and are connected to the solenoid valve assembly 50. The oxygen outlet is located on the top side of the tower and is connected to the oxygen storage tank 80. Each molecular sieve tower also has an oxygen sensor at its oxygen outlet to detect the oxygen concentration and determine whether the molecular sieve tower is saturated with adsorption.

[0038] Solenoid valve assembly 50 includes a first directional valve 51 and a second directional valve 52 (see...) Figure 4The first reversing valve 51 connects the outlet of the radiator 41 to the inlet of each molecular sieve tower, and is used to switch the connection between the radiator 41 and each molecular sieve tower, allowing compressed air to enter the designated molecular sieve tower. The second reversing valve 52 connects the nitrogen vent of each molecular sieve tower to the inlet of the nitrogen venting silencer 70, and is used to switch the connection between each molecular sieve tower and the nitrogen venting silencer 70, allowing nitrogen to be discharged from the designated molecular sieve tower.

[0039] As an example, the molecular sieve assembly 60 includes a first molecular sieve tower 61 and a second molecular sieve tower 62; a first reversing valve 51 has an inlet and two first working ports, the inlet being connected to the outlet of the radiator 41 via a pipeline, and the two first working ports being connected to the inlets of the first molecular sieve tower 61 and the second molecular sieve tower 62 respectively; a second reversing valve 52 has an outlet and two second working ports, the outlet being connected to the inlet of the nitrogen exhaust silencer 70 via a pipeline, and the two second working ports being connected to the nitrogen exhaust ports of the first molecular sieve tower 61 and the second molecular sieve tower 62 respectively; the oxygen outlets of the first molecular sieve tower 61 and the second molecular sieve tower 62 are connected to a common oxygen outlet via a pipeline, which is connected to the inlet of the oxygen storage tank 80.

[0040] The nitrogen exhaust silencer 70 is installed in the middle area of ​​the base plate 11. The top of the nitrogen exhaust silencer 70 is provided with an air inlet, which is connected to the second reversing valve 52 through a pipeline. The bottom of the nitrogen exhaust silencer 70 is provided with an air outlet, which passes downward through the base plate 11. The nitrogen exhaust silencer 70 is used to reduce the noise generated when nitrogen is discharged.

[0041] The oxygen storage tank 80 is located above the nitrogen exhaust silencer 70. An air inlet is provided on the side of the oxygen storage tank 80, which is connected to the top of the molecular sieve assembly 60. An air outlet is provided at the bottom of the oxygen storage tank 80, which is connected to the air inlet of the pressure regulating valve 90 through a pipeline.

[0043] The inlet of the one-way valve 100 is connected to the outlet of the pressure regulating valve 90. The outlet of the one-way valve 100 is used to connect to the oxygen distribution terminal in the vehicle through a pipeline. The one-way valve 100 is used to prevent oxygen backflow.

[0044] The control unit 110 is mounted on the bottom surface of the base plate 11. The control unit 110 is communicatively connected to the air compressor 30, the fan 42 of the heat dissipation assembly 40, the first reversing valve 51 and the second reversing valve 52 of the solenoid valve group 50, the oxygen sensor of the molecular sieve assembly 60, and the pressure regulating valve 90.

[0045] Figure 4A schematic diagram of the gas path of a vehicle-mounted oxygen generator provided in this application embodiment is shown below. Figure 4 As shown, and in combination Figures 1 to 3 The working principle of this vehicle-mounted oxygen generator 1000 is as follows: the control unit 110 controls the operation of the air compressor 30. After the air is filtered by the intake filter 20, it enters the air compressor 30. The air compressor 30 compresses the air and delivers it to the radiator 41. After the compressed air is cooled by the radiator 41, it enters the first reversing valve 51 of the solenoid valve group 50.

[0046] The first reversing valve 51 can first introduce compressed air into the first molecular sieve tower 61 of the molecular sieve assembly 60, allowing nitrogen in the compressed air to be adsorbed by the first molecular sieve tower 61, while oxygen is discharged and stored in the oxygen storage tank 80. When the oxygen sensor at the oxygen outlet of the first molecular sieve tower 61 detects a significant decrease in oxygen concentration, it indicates that the first molecular sieve tower 61 is saturated. At this time, the oxygen sensor sends a signal to the control unit 110, which controls the first reversing valve 51 to switch, introducing compressed air into the second molecular sieve tower 62, where nitrogen is adsorbed and oxygen is discharged. At the same time, the control unit 110 controls the second reversing valve 52 to switch, allowing the nitrogen adsorbed by the first molecular sieve tower 61 to be discharged through the second reversing valve 52. When the oxygen sensor at the outlet of the second molecular sieve tower 62 detects a significant decrease in oxygen concentration, it indicates that the second molecular sieve tower 62 is saturated with adsorption. At this time, the oxygen sensor sends a signal to the control unit 110, which controls the first reversing valve 51 and the second reversing valve 52 to switch, so that the first molecular sieve tower 61 adsorbs nitrogen and discharges oxygen, while the second molecular sieve tower 62 discharges nitrogen. This cycle is repeated to achieve continuous oxygen production and nitrogen discharge. The discharged nitrogen is discharged to the external environment after being reduced in noise by the nitrogen exhaust silencer 70, and the oxygen in the oxygen storage tank 80 can be stably supplied to the oxygen distribution terminal in the vehicle after passing through the pressure regulating valve 90 and the one-way valve 100.

[0047] This application also provides an in-vehicle oxygen generation system, which includes the aforementioned in-vehicle oxygen generator 1000, an in-vehicle oxygen distribution terminal, and a remote control switch. The in-vehicle oxygen distribution terminal is connected to the one-way valve 100 of the in-vehicle oxygen generator 1000 via a pipeline, for supplying oxygen to the vehicle interior. The remote control switch is communicatively connected to the control unit 110 of the in-vehicle oxygen generator 1000, for remotely controlling the in-vehicle oxygen generator 1000.

[0048] This application also provides a vehicle that includes the above-described on-board oxygen generation system.

Figure 6This application provides a schematic diagram of the structure of a hidden interior trim panel 1 and an onboard oxygen generator 1000 within a vehicle, as shown in the embodiment of this application. Figure 5 and Figure 6 As shown, the vehicle-mounted oxygen generator 1000 is installed in the mounting area 3 at the right rear of the vehicle interior. The vehicle-mounted oxygen generator 1000 is fixed to the vehicle body structure by means of mounting bracket 10 and fasteners. The radiator 41 is directly opposite the ventilation opening 2 at the right rear of the vehicle body. The vehicle-mounted oxygen generator 1000 is covered by the interior trim panel 1 to ensure the aesthetics of the vehicle interior.

[0050] In summary, the vehicle-mounted oxygen generator, vehicle-mounted oxygen generation system, and vehicle provided in this application embodiment are integrated and modularly designed. The vehicle-mounted oxygen generator integrates the intake filter, air compressor, heat dissipation component, solenoid valve group, and molecular sieve component, which are connected in sequence, on a mounting bracket. This facilitates installation in the vehicle. The molecular sieve component includes at least two molecular sieve towers for adsorbing nitrogen and discharging oxygen. The solenoid valve group can switch the intake and nitrogen discharge of the molecular sieve component, allowing compressed air to enter a designated molecular sieve tower and nitrogen to be discharged from a designated molecular sieve tower, thereby achieving continuous oxygen generation and nitrogen discharge. The vehicle-mounted oxygen generator has the advantage of high efficiency. The vehicle-mounted oxygen generation system includes the aforementioned vehicle-mounted oxygen generator, an in-vehicle oxygen distribution terminal, and a remote control switch. The remote control switch allows for remote control of the oxygen supply from the vehicle-mounted oxygen generator, making the vehicle-mounted oxygen generation system easy to operate.
