Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular to a vehicle, a sunroof assembly and an air circulation method for a vehicle cabin. Background Art

[0002] In recent years, self-driving in plateau environments has become increasingly popular. Unlike the plain environment, the special geographical environment of the plateau area leads to a decrease in atmospheric pressure and a thin oxygen content. When passengers drive or ride in a vehicle on the plateau, they are prone to hypoxia symptoms, which not only affects their own health, but also affects driving safety. In the Chinese invention patent application with publication number CN117360178A, a vehicle oxygen supplementation system is disclosed, which includes a vehicle space and an oxygen generator. The control method for controlling the vehicle oxygen supplementation system includes the following steps: obtaining the altitude of the vehicle as a first altitude; when the first altitude is greater than the first preset altitude and less than or equal to the second preset altitude, the vehicle air conditioner transports the air outside the vehicle toward the inside of the vehicle; when the first altitude is greater than the second preset altitude, the vehicle air conditioner transports the air outside the vehicle toward the inside of the vehicle, and the oxygen generator provides oxygen to the inside of the vehicle. It can be seen that the prior art only determines the oxygen supplementation method according to the current altitude of the vehicle, without taking into account the differences in the passengers' own conditions, and cannot truly meet the needs of passengers.

DETAILED DESCRIPTION

[0031] Before describing in detail any embodiment of the present invention, it should be understood that the present invention is not limited in its application to the construction and arrangement details of the components described below or illustrated in the following figures. The present invention can have other embodiments and can be practiced or carried out in various ways.

[0032] Furthermore, on the first aspect, in the disclosure of the present invention, the orientations or positional relationships indicated by terms such as “longitudinal”, “transverse”, “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside” and “outside” are based on the orientations or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore the above terms cannot be understood as limitations on the present invention; on the second aspect, the term “one” should be understood as “at least one” or “one or more”, that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term “one” cannot be understood as a limitation on the quantity.

[0033] Reference Figure 1 A vehicle in a preferred embodiment of the present invention includes a vehicle body 10 and a sunroof assembly 20, wherein the sunroof assembly 20 includes a sunroof body 21, and the sunroof body 21 further includes a sunroof frame 211 and a sunroof glass 212 movably mounted on the sunroof frame 211, and the sunroof frame 211 is mounted on the roof of the vehicle body 10 to install the sunroof assembly 20 on the roof of the vehicle body 10.

[0034] The sunroof assembly 20 has an open state and a closed state. The sunroof assembly 20 can be switched between the open state and the closed state by driving the sunroof glass 212 to move relative to the sunroof frame 211. When the sunroof assembly 20 is in the open state, the sunroof assembly 20 forms an opening, and the sunroof assembly 20 allows the vehicle cabin of the vehicle to communicate with the external environment, allowing the air in the vehicle cabin to exchange with the air in the external environment to achieve natural circulation of the air in the vehicle cabin. When the sunroof assembly 20 is in the closed state, the sunroof assembly 20 has no opening, and the sunroof assembly 20 prevents the vehicle cabin of the vehicle from communicating with the external environment.

[0035] Different from the prior art, Figures 1 to 13In this specific example of the present invention shown, the sunroof assembly 20 further includes an oxygen generator 22, which can generate oxygen and replenish oxygen into the vehicle cabin. In this way, when passengers drive or ride in the vehicle in a plateau environment, if symptoms of hypoxia occur, the oxygen generator 22 can generate oxygen and replenish oxygen into the vehicle cabin, which can not only prevent passengers from suffering from hypoxia in the plateau, but also avoid unnecessary oxygen replenishment operations. If no symptoms of hypoxia occur, the sunroof assembly 20 can be allowed to switch to the open state to allow the air in the vehicle cabin to exchange with the air in the external environment to achieve natural circulation of the air in the vehicle cabin.

[0036] In the present invention, the oxygen production device 22 adopts the electrolysis of water oxygen production scheme, so that the raw materials for oxygen production can be easily obtained. In the plateau environment, especially in the uninhabited area or sparsely populated scene of the plateau, the oxygen production device 22 will not lose the oxygen production function because the raw materials for oxygen production are not easy to obtain.

[0037] Reference Figures 4 to 9 The oxygen generator 22 has a water replenishment port 2201, a hydrogen outlet 2202 and an oxygen outlet 2203. The water replenishment port 2201 and the hydrogen outlet 2202 of the oxygen generator 22 are located above the skylight frame 211, so that the water replenishment port 2201 and the hydrogen outlet 2202 of the oxygen generator 22 are located outside the vehicle cabin, and the oxygen outlet 2203 of the oxygen generator 22 is located below the skylight frame 211, so that the oxygen outlet 2203 of the oxygen generator 22 is located inside the vehicle cabin.

[0038] Passengers can add water to the oxygen generator 22 through the water replenishment port 2201 of the oxygen generator 22. For example, drinking water (mineral water, purified water, etc.) can be added to the oxygen generator 22 through the water replenishment port 2201 of the oxygen generator 22. The oxygen generator 22 obtains hydrogen and oxygen by electrolyzing water to produce oxygen. The hydrogen can be discharged to the external environment of the vehicle cabin through the hydrogen outlet 2202 of the oxygen generator 22, and the oxygen can be discharged into the vehicle cabin through the oxygen outlet 2203 of the oxygen generator 22, thereby realizing the oxygen replenishment operation of the vehicle cabin. It can be understood that since the hydrogen outlet 2202 of the oxygen generator 22 is located outside the vehicle cabin, the hydrogen generated in the process of electrolyzing water to produce oxygen can be prevented from entering the vehicle cabin to avoid safety hazards.

[0039] Reference Figure 4 , Figure 6 and Figure 7, the oxygen generator 22 is arranged on the front frame 2111 of the skylight frame 211, so that when the skylight glass 212 is driven to move relative to the skylight frame 211 and the skylight assembly 20 is in the open state, the water replenishment port 2201 of the oxygen generator 22 is adjacent to the opening of the skylight assembly 20, so that the passenger can replenish water to the oxygen generator 22 through the water replenishment port 2201 through the opening of the skylight assembly 20 in the vehicle cabin, which is crucial for passenger safety. It can be understood that due to the large number of uninhabited areas and sparsely populated areas in the plateau environment, there are many wild animals living in the plateau environment. If the passengers get off the car rashly, they are easily attacked by wild animals and there are great safety hazards. In a preferred example of the present invention, by arranging the oxygen generator 22 on the front frame 2111 of the skylight frame 211, the hidden danger can be eliminated, making the water replenishment operation of the oxygen generator 22 safer.

[0040] Continue to refer to the attached Figures 4 to 13 The oxygen production device 22 includes a shell 221, a water supply pipeline 222, a hydrogen pipeline 223, an oxygen pipeline 224 and an electrode part 225, wherein the shell 221 has an oxygen production chamber 2211, the water supply pipeline 222, the hydrogen pipeline 223 and the oxygen pipeline 224 are respectively arranged in the shell 221, and the water supply port 2201 of the oxygen production device 22 is formed in the water supply pipeline 222, and the hydrogen outlet 2202 of the oxygen production device 22 is formed in the hydrogen outlet 2202. The oxygen pipeline 223, the oxygen outlet 2203 of the oxygen production device 22 is formed in the oxygen pipeline 224, wherein the electrode part 225 includes a cathode electrode 2251 and an anode electrode 2252, the cathode electrode 2251 and the anode electrode 2252 are respectively arranged at different positions of the oxygen production chamber 2211 of the shell 221, and the pipeline opening of the hydrogen pipeline 223 is adjacent to the cathode electrode 2251, and the pipeline opening of the oxygen pipeline 224 is adjacent to the anode electrode 2252.

[0041] The hydrogen pipeline 223 may be a hose, and the hydrogen pipeline 223 may be arranged along the extension direction of the skylight frame 211, and the end of the hydrogen pipeline 223 extends to the top of the skylight frame 211, so that the hydrogen outlet 2202 of the oxygen generator 22 is located above the skylight frame 211. The oxygen pipeline 224 may be a hose, and the oxygen pipeline 224 may be arranged along the extension direction of the skylight frame 211, and the end of the oxygen pipeline 224 extends to the bottom of the skylight frame 211, so that the oxygen outlet 2203 of the oxygen generator 22 is located below the skylight frame 211.

[0042] Furthermore, the shell 221 has a hydrogen guide tube 22101 and an oxygen guide tube 22102, the inner end of the hydrogen guide tube 22101 extends to the oxygen production chamber 2211 of the shell 221, the inner end of the oxygen guide tube 22102 is connected to the oxygen production chamber 2211 of the shell 221, the outer end of the hydrogen guide tube 22101 and the outer end of the oxygen guide tube 22102 of the shell 221 protrude from the surface of the shell 221 respectively, and one end of the hydrogen pipeline 223 The outer end of the hydrogen guide tube 22101 of the shell 221 is airtightly mounted on the outer end of the hydrogen guide tube 22102 of the shell 221 to set the hydrogen pipeline 223 in the shell 221, and one end of the oxygen pipeline 224 is airtightly mounted on the outer end of the oxygen guide tube 22102 of the shell 221 to set the oxygen pipeline 224 in the shell 221, so that the pipeline mouth of the hydrogen pipeline 223 can be adjacent to the cathode electrode 2251, and the pipeline mouth of the oxygen pipeline 224 can be adjacent to the anode electrode 2252.

[0043] Water is allowed to be replenished to the oxygen production chamber 2211 of the shell 221 through the water replenishment pipe 222. When water exists in the oxygen production chamber 2211 of the shell 221, at least a portion of the cathode electrode 2251 and the anode electrode 2252 are immersed in water. When the cathode electrode 2251 and the anode electrode 2252 are powered on, the cathode electrode 2251 and the anode electrode 2252 cooperate with each other to electrolyze water to form hydrogen and oxygen. Since the pipe opening of the hydrogen pipe 223 is adjacent to the cathode electrode 2251, hydrogen can be discharged through the hydrogen pipe 223, and since the pipe opening of the oxygen pipe 224 is adjacent to the anode electrode 2252, oxygen can be discharged through the oxygen pipe 224.

[0044] It should be noted that the cathode electrode 2251 and the anode electrode 2252 of the electrode portion 225 of the oxygen generator 22 may be connected to the circuit of the skylight body 21 to allow the skylight body 21 to control the power-on status of the cathode electrode 2251 and the anode electrode 2252 .

[0045] Reference Figure 4 and Figure 5The front frame 2111 of the skylight frame 211 has a pipe hole 21111, and the shell 221 of the oxygen generator 22 is fixedly installed below the front frame 2111. For example, the shell 221 can be locked to the front frame 2111 by a screw, and the top of the water supply pipe 222 and the end of the hydrogen pipe 223 extend to the top of the skylight frame 211 through the pipe hole 21111 of the front frame 2111, so that the water supply port 2201 and the hydrogen outlet 2202 of the oxygen generator 22 are both located above the skylight frame 211.

[0046] Preferably, in an example of the present invention, the cathode electrode 2251 and the anode electrode 2252 of the electrode part 225 are both in sheet shape, and the extension direction of the cathode electrode 2251 and the extension direction of the anode electrode 2252 are consistent with the length and width direction of the shell 221. In this way, the oxygen generator 22 can have a thinner thickness dimension, reduce the height of the oxygen generator 22 protruding toward the vehicle cabin, and even prevent the oxygen generator 22 from protruding toward the vehicle cabin. At the same time, by designing the cathode electrode 2251 and the anode electrode 2252 to be sheet-shaped, the contact area between the cathode electrode 2251 and the anode electrode 2252 and water can be increased, which is conducive to improving the oxygen production efficiency of the oxygen generator 22.

[0047] It can be understood that in the process of electrolyzing water to produce oxygen, in order to prevent the generated hydrogen from entering the oxygen pipeline 224 and to prevent the generated oxygen from entering the hydrogen pipeline 223, the oxygen production chamber 2211 of the shell 221 is isolated into a relatively independent hydrogen chamber 22111 and an oxygen chamber 22112, the inner end of the hydrogen guide pipe 22101 of the shell 221 extends to the hydrogen chamber 22111 and the cathode electrode 2251 is located in the hydrogen chamber 22111, and the oxygen guide pipe 22102 of the shell 221 is connected to the oxygen chamber 22112. In the oxygen chamber 22112 and the anode electrode 2252 is located in the oxygen chamber 22112, in this way, in the process of electrolyzing water to produce oxygen, the hydrogen generated near the cathode electrode 2251 is first collected in the hydrogen chamber 22111 and then enters the hydrogen guide pipe 22101 and the hydrogen pipeline 223 of the shell 221, and the oxygen generated near the anode electrode 2252 is first collected in the oxygen chamber 22112 and then enters the oxygen guide pipe 22102 and the oxygen pipeline 224 of the shell 221. Since the hydrogen chamber 22111 and the oxygen chamber 22112 are relatively independent, in the process of electrolyzing water to produce oxygen, the hydrogen collected in the hydrogen chamber 22111 is prevented from entering the oxygen chamber 22112, and accordingly, the oxygen collected in the oxygen chamber 22112 is prevented from entering the hydrogen chamber 22111. It should be noted that the bottom of the hydrogen chamber 22111 and the bottom of the oxygen chamber 22112 are connected.

[0048] Specifically, refer to the attached Figures 9 to 13The shell 221 includes a shell body 2212, a bottom cover 2213 and a partition plate 2214. The shell body 2212 has a first cavity 22121. The partition plate 2214 is arranged on the bottom cover 2213, and the extension direction of the partition plate 2214 and the extension direction of the bottom cover 2213 are perpendicular to each other. The partition plate 2214 has a water flow channel 22141, and the water flow channel 22141 runs through the opposite sides of the partition plate 2214. In an example of the present invention, the partition plate 2214 and the bottom cover 2213 can be an integrated structure. For example, the bottom cover 2213 and the partition plate 2214 can be formed integrally by a plastic material by means of an injection molding process. The cathode electrode 2251 and the anode electrode 2252 of the electrode part 225 are respectively arranged on the bottom cover 2213, and the cathode electrode 2251 is located on one side of the partition plate 2214, and the anode electrode 2252 is located on the other side of the partition plate 2214. In one example of the present invention, the cathode electrode 2251 and the anode electrode 2252 can be respectively arranged on the bottom cover 2213 by glue. The bottom cover 2213 is watertightly mounted on the shell body 2212, and the bottom cover 2213 is used to close the cavity of the first cavity 22121 of the shell body 2212, so that the first cavity 22121 of the shell body 2212 forms the oxygen-generating cavity 2211 of the shell body 221 between the shell body 2212 and the bottom cover 2213, and the partition plate 2214 is inserted into the first cavity 22121 of the shell body 2212, and is used to separate the first cavity 22121 of the shell body 2212 into the hydrogen chamber 22111 and the oxygen chamber 22112, and the water flow channel 22141 of the partition plate 2214 communicates the bottom of the hydrogen chamber 22111 and the bottom of the oxygen chamber 22112. Optionally, in other examples of the present invention, the partition plate 2214 and the shell body 2212 may be formed integrally.

[0049] It is worth mentioning that the specific manner in which the bottom cover 2213 is watertightly mounted on the shell body 2212 is not limited in the present invention. For example, in some examples of the present invention, a screw can be used to lock the bottom cover 2213 on the shell body 2212. On this basis, in order to further increase the watertightness of the installation position of the bottom cover 2213 and the shell body 2212, a sealing gasket can also be provided at the installation position of the bottom cover 2213 and the shell body 2212.

[0050] Reference Fig.11 and Fig.12The shell body 2212 further has an embedding groove 22122, and the embedding groove 22122 is connected to the first cavity 22121, wherein the edge of the partition plate 2214 is embedded in the embedding groove 22122 of the shell body 2212. In this way, on the one hand, the shell body 2212 and the bottom cover 2213 cooperate with each other so that the partition plate 2214 can reliably stand in the first cavity 22121 of the shell body 2212, and is used to separate the first cavity 22121 into the hydrogen chamber 22111 and the oxygen chamber 22112, on the other hand, are conducive to increasing the sealing performance of the installation position of the shell body 2212 and the partition plate 2214, so that the hydrogen chamber 22111 and the oxygen chamber 22112 formed on the opposite sides of the partition plate 2214 are relatively independent, so that in the process of electrolysis of water to produce oxygen, the hydrogen collected in the hydrogen chamber 22111 is prevented from entering the oxygen chamber 22112, and correspondingly, the oxygen collected in the oxygen chamber 22112 is prevented from entering the hydrogen chamber 22111.

[0051] Continue to refer to the attached Figures 9 to 13 The oxygen generator 22 further includes a filter portion 226 . The shell body 2212 has a second cavity 22123 . The filter portion 226 is located in the second cavity 22123 of the shell body 2212 .

[0052] The shell 221 further includes an isolation part 2215 and a top cover 2216, wherein the isolation part 2215 has a gas through hole 22151, and the isolation part 2215 is clamped between the shell body 2212 and the top cover 2216. The isolation part 2215 can not only be used to close the cavity opening of the second cavity 22123 of the shell body 2212, but also can prevent the formation of a gap between the shell body 2212 and the top cover 2216 to cause gas leakage. The gas through hole 22151 of the isolation part 2215 is connected to the second cavity 22123 of the shell body 2212. In one example of the present invention, a screw can be used to install the top cover 2216 and the shell body 2212 to each other, and allow the edge of the isolation portion 2215 to be clamped between the top cover 2216 and the shell body 2212, thereby not only ensuring that the isolation portion 2215 closes the opening of the second cavity 22123 of the shell body 2212, but also preventing a gap from being formed between the shell body 2212 and the top cover 2216.

[0053] The shell 221 forms a gas passage 2217 between the isolation part 2215 and the top cover 2216, and one end of the gas passage 2217 is connected to the gas through hole 22151 of the isolation part 2215. The oxygen generator 22 further includes an air guide duct 228, and opposite ends of the air guide duct 228 extend to the oxygen chamber 22112 of the shell 221 and the second cavity 22123 of the shell body 2212, respectively, for connecting the oxygen chamber 22112 and the second cavity 22123. The oxygen guide pipe 22102 of the shell 221 is disposed on the top cover 2216 and connected to the gas passage 2217, so that the oxygen guide pipe 22102 of the shell 221 is connected to the oxygen chamber 22112. After oxygen is collected in the oxygen chamber 22112, the oxygen can enter the second cavity 22123 of the shell body 2212 through the gas guide pipe 228, and the oxygen is filtered by the filter part 226 when flowing toward the gas through hole 22151 of the isolation part 2215 to obtain relatively pure oxygen, and the filtered oxygen can be further discharged through the gas passage 2217 and the oxygen guide pipe 22102 of the shell 221. In a specific example of the present invention, the filter part 226 can be activated carbon, which is used to filter ozone and the like in oxygen.

[0054] Reference Fig.11 The top cover 2216 has a first cover groove 22161 and a second cover groove 22162, wherein the first cover groove 22161 is located at one end of the top cover 2216, and the second cover groove 22162 extends from the first cover groove 22161 to the other end of the top cover 2216. After the top cover 2216 is installed on the shell body 2212, the second cover groove 22162 of the top cover 2216 forms the gas passage 2217 of the shell body 221 between the top cover 2216 and the isolation part 2215, and the first cover groove 22161 is located above the gas through hole 22151 of the isolation part 2215. The first cover groove 22161 of the top cover 2216 may have a larger space, so that the filtered oxygen can be first collected in the first cover groove 22161 of the top cover 2216, and then flow to the direction of the second pipe 2242 through the gas passage 2217 formed by the second cover groove 22162 of the top cover 2216. Figures 10 to 13The air duct 228 of the oxygen pipe 224 extends to one end of the second cavity 22123 of the shell body 2212, and the gas through hole 22151 of the isolation part 2215 is connected to the other end of the second cavity 22123 of the shell body 2212. In this way, after oxygen enters the second cavity 22123 of the shell body 2212 through the air duct 228, it needs to pass through the entire filtering part 226 to reach the gas through hole 22151 of the isolation part 2215, so as to improve the filtering effect of oxygen.

[0055] Preferably, the isolation portion 2215 is made of silicone, so that the isolation portion 2215 can not only seal the opening of the second cavity 22123 of the shell body 2212 and prevent the formation of a gap between the shell body 2212 and the top cover 2216 to cause air leakage, but also has the function of absorbing ozone in oxygen, that is, the isolation portion 2215 can also provide a filtering effect on oxygen.

[0056] Preferably, refer to the attached Fig.10 and Fig.11 The isolation part 2215 has a first avoidance hole 22152 and a second avoidance hole 22153, and the filter part 226 has a third avoidance hole 2261 and a fourth avoidance hole 2262, wherein the position of the first avoidance hole 22152 of the isolation part 2215 corresponds to the position of the third avoidance hole 2261 of the filter part 226, and is used to avoid the hydrogen pipeline 223, that is, the inner end of the hydrogen guide pipe 22101 of the shell 221 is extended after passing through the first avoidance hole 22152 of the isolation part 2215 and the third avoidance hole 2261 of the filter part 226 in sequence. It extends to the hydrogen chamber 22111 of the shell 221, wherein the position of the second avoidance hole 22153 of the isolation part 2215, the fourth avoidance hole 2262 of the filter part 226 and the shell through hole 22125 of the shell body 2212 correspond to each other, and is used to avoid the water supply pipe 222, that is, the bottom of the water supply pipe 222 extends to the hydrogen chamber 22111 of the shell 221 after passing through the second avoidance hole 22153 of the isolation part 2215, the fourth avoidance hole 2262 of the filter part 226 and the shell through hole 22125 of the shell body 2212 in sequence.

[0057] In addition, refer to the attached Fig.11 and Fig.12The oxygen generating device 22 further includes a pump body 227, and the air guide duct 228 is composed of a first tube body 2281 and a second tube body 2282, wherein one end of the first tube body 2281 extends to the oxygen chamber 22112 of the shell body 221, and the other end extends to the air inlet of the pump body 227, one end of the second tube body 2282 extends to the second cavity 22123 of the shell body 2212, and the other end extends to the air outlet of the pump body 227, wherein the pump body 227 is used to pump the oxygen in the oxygen chamber 22112 of the shell body 221 into the second cavity 22123 of the shell body 2212, so that the oxygen can flow smoothly through the filtering part 226. Preferably, the shell body 2212 has a third cavity 22124 , the pump body 227 is installed in the third cavity 22124 of the shell body 2212 , and the isolation portion 2215 can be used to close the cavity opening of the third cavity 22124 of the shell body 2212 .

[0058] During driving, the vehicle's measuring device can measure the altitude of the vehicle's location to determine whether the vehicle is driving in a plateau environment. The measuring device can be, but is not limited to, a GPS or a barometer. Figure 2 When the measurement result of the measuring device is that the altitude of the vehicle's location is greater than 1000 meters, it can be judged that the vehicle is traveling in a plateau environment. Correspondingly, when the measurement result of the measuring device is that the altitude of the vehicle's location is less than 1000 meters, it can be judged that the vehicle is not traveling in a plateau environment.

[0059] It is understandable that when the vehicle is traveling in a plateau environment, passengers may face a hypoxia problem. In fact, when the vehicle is traveling in a plateau environment, whether the passenger faces a hypoxia problem depends on the passenger's own state. Therefore, after judging that the vehicle is traveling in a plateau environment, the present invention also needs to further obtain the passenger's own state in the vehicle cabin. Subsequently, according to the altitude of the vehicle and the physical state of the passenger in the vehicle cabin, a method of supplementing oxygen to the vehicle cabin is selected, wherein when it is judged that the passenger is not hypoxic according to the altitude of the vehicle and the physical state of the passenger in the vehicle cabin, the vehicle maintains the current state, and when it is judged that the passenger is hypoxic according to the altitude of the vehicle and the physical state of the passenger in the vehicle cabin, the vehicle starts the oxygen generator 22 of the sunroof assembly 20, and the oxygen generator 22 obtains oxygen by electrolyzing water to produce oxygen, and replenishes oxygen to the vehicle cabin to alleviate the passenger's hypoxia problem, which is crucial for the passenger's own safety and driving safety.

[0060] In some examples of the present invention, the passenger's breathing frequency can be detected by a microwave detection device installed in the vehicle cabin to obtain the passenger's breathing status, and whether the passenger is hypoxic can be determined based on the passenger's breathing status. Specifically, after the vehicle is traveling in a plateau environment, if the microwave detection device detects that the passenger's breathing frequency is too high, it indicates that the passenger in the vehicle cabin is short of breath. At this time, it can be determined that the passenger has a hypoxia problem. At this time, the vehicle can start the oxygen generator 22 of the sunroof assembly 20 to produce oxygen to supplement oxygen to the vehicle cabin. In other examples of the present invention, the passenger's blood oxygen saturation can be obtained through a smart watch worn by the passenger to determine whether the passenger is hypoxic. In this case, the smart watch worn by the passenger needs to be connected to the vehicle's on-board computer so that the vehicle's on-board computer obtains blood oxygen saturation data from the smart watch worn by the passenger. Specifically, after the vehicle travels in a plateau environment, if the blood oxygen saturation of the passengers in the vehicle cabin drops below 95%, it can be determined that the passengers have an oxygen deficiency problem. At this time, the vehicle can start the oxygen generator 22 to produce oxygen to supplement oxygen to the vehicle cabin.

[0061] In other words, refer to the attached Figure 3 The present invention also provides an air circulation method for air circulation in the vehicle cabin, wherein the air circulation method comprises the following steps: S1, obtaining the altitude of the vehicle; S2, obtaining the physical condition of the passengers in the vehicle cabin; S3, selecting a mode of air circulation in the vehicle cabin according to the altitude of the vehicle and the physical condition of the passengers in the vehicle cabin.

[0062] Preferably, in step S2, the respiratory state of the passenger is obtained, and in step S3, it is determined whether there is hypoxia according to the altitude of the vehicle and the respiratory state of the passenger in the vehicle cabin. In case of hypoxia, oxygen is produced by the oxygen generator 22 of the sunroof assembly 20 to supplement oxygen into the vehicle cabin. Alternatively, in step S2, the blood oxygen saturation of the passenger is obtained, and in step S3, it is determined whether there is hypoxia according to the altitude of the vehicle and the blood oxygen saturation of the passenger in the vehicle cabin. In case of hypoxia, oxygen is produced by the oxygen generator 22 of the sunroof assembly 20 to supplement oxygen into the vehicle cabin. In case of no hypoxia, the sunroof assembly 20 allows the air in the vehicle cabin to be exchanged with the air of the external environment.

[0063] In step S3, refer to the attached Fig.13When the cathode electrode 2251 and the anode electrode 2252 are powered, the cathode electrode 2251 and the anode electrode 2252 cooperate with each other, hydrogen is generated near the cathode electrode 2251 and the hydrogen is collected in the hydrogen chamber 22111 of the shell 221, and subsequently, the hydrogen collected in the hydrogen chamber 22111 of the shell 221 is discharged through the hydrogen pipeline 223, and oxygen is generated near the anode electrode 2252 and the anode is collected in the oxygen chamber 22112 of the shell 221, and the pump body 227 is collected in the shell when working. The oxygen in the oxygen chamber 22112 of 221 is pumped into the second cavity 22123 of the shell body 2212, and the oxygen is filtered by the filter part 226 and the isolation part 2215 when flowing toward the gas through hole 22151 of the isolation part 2215, and the filtered oxygen further reaches the first cover groove 22161 of the top cover 2216, and then the filtered oxygen reaches the oxygen pipe 224 through the gas passage 2217 of the shell 221, and is discharged to the vehicle cabin through the oxygen pipe 224, so as to supplement oxygen to the vehicle cabin.
