[0028] In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work are protected by the present application.

[0029] As the trend of global warming becomes increasingly obvious, rainstorms and heavy precipitation events have become more frequent in some areas. When a car is driving in a heavy precipitation environment, it is easy for the car air conditioner to get water in. Water in the car air conditioner can cause the air conditioner paper filter to become wet and moldy and produce odor. If it is not replaced in time, it may endanger human health. In addition, water in the car air conditioner may burn the electrical components in the car air conditioner and enter the passenger compartment, causing the entire vehicle to be scrapped. Therefore, a waterproof control method is urgently needed to achieve effective water blocking and prevent rainwater from entering the fresh air outlet.

[0030] In view of this, the present application proposes a waterproof method for a vehicle air conditioner, which can transport the water falling into the middle water hole to the water outlet when there is a risk of water ingress, increase the drainage efficiency, and thus control the water level in the air chamber below the fresh air outlet to prevent water from entering the air conditioner.

[0031] In order to illustrate the technical solution of the present application, a specific embodiment is provided below for illustration.

[0032] Figure 1 The present invention provides a schematic diagram of the implementation process of a waterproof method for a vehicle air conditioner, which can be applied to a vehicle. The vehicle can refer to a hybrid vehicle, a pure electric vehicle, a fuel vehicle or other types of vehicles, which is not limited by the present invention.

[0033] In the embodiment of the present application, the above vehicle may be equipped with a vehicle air conditioner and an air chamber. The air chamber is used to provide an air inlet channel when the vehicle air conditioner is in an external circulation mode, so that the external air enters the fresh air outlet through the air chamber and reaches the passenger compartment.

[0034] On a rainy day, the flow path of rainwater from falling on the car to leaving the car is as follows: Figure 2 As shown, when water drops fall on the front windshield of the vehicle, part of the rainwater is thrown to both sides by the wiper, and the other part remains on the glass surface, flows to the ventilation cover plate under the action of gravity, and enters the air chamber below the ventilation cover plate along the water flow holes on the ventilation cover plate. The water flow holes may include a middle water flow hole and two side water flow holes. The middle water flow hole is arranged at the middle and lower part of the ventilation cover plate, and the two side water flow holes include a left water flow hole and a right water flow hole respectively arranged on both sides of the ventilation cover plate.

[0035] like Figure 3 As shown, in the prior art, rainwater falls from the water flow holes onto the bottom plate of the air chamber. Due to the collision, some water drops will splash to a certain height. In this process, the splashed water drops are very likely to enter the fresh air outlet under the action of the fresh air. The water flowing from the left and right water flow holes flows into the air chamber outlets arranged on both sides of the bottom plate of the air chamber, while the water flowing from the middle water flow hole will flow to both sides due to the height difference between the center of the bottom plate and the two sides of the bottom plate.

[0036] In order to prevent rainwater from entering the fresh air inlet, in an embodiment of the present application, the air chamber of the vehicle may include a baffle arranged on a slide rail, which is used to slide back and forth along the slide rail below the middle water flow hole of the ventilation cover and above the water outlet of the air chamber.

[0037] In some embodiments of the present application, the baffle may include a first baffle and / or a second baffle.

[0038] Specifically, in some embodiments of the present application, the baffle includes a first baffle, and the first baffle is used to slide back and forth along the slide rail below the middle water flow hole of the ventilation cover and above the air chamber water outlet on the side of the fresh air outlet. For example, when the fresh air outlet is located on the left side of the vehicle, the first baffle can slide back and forth below the middle water flow hole and above the air chamber water outlet on the left side, and then disperse the water flowing into the middle water flow hole to the top of the air chamber water outlet on the side of the fresh air outlet.

[0039] The first baffle has a three-layer structure, and a first opening is provided on the top layer of the three-layer structure. Specifically, the top layer of the first baffle has an arc-shaped structure that bulges upward (i.e., toward the side of the water flow hole), and the top layer may be higher than the height of the air chamber sheet metal, and a first opening is provided on the top layer. The middle layer of the first baffle is flush with the air chamber sheet metal. The bottom layer adopts a soft material to prevent interference with the air chamber sheet metal, and the soft material includes but is not limited to rubber, foam plastic, and polymer material. Since the first opening is provided on the top layer of the first baffle, on the one hand, the risk of water splashing into the fresh air outlet can be reduced, and on the other hand, the water level in the air chamber can be prevented from being too high.

[0040] In some embodiments of the present application, the baffle may include a second baffle, which is used to slide back and forth along the slide rail below the middle water flow hole of the ventilation cover and above the water outlet of the air chamber on the opposite side of the fresh air outlet. For example, when the fresh air outlet is located on the left side of the vehicle, the second baffle may slide back and forth below the middle water flow hole and above the water outlet of the right air chamber, and then disperse the water flowing into the middle water flow hole to the top of the water outlet of the air chamber on the opposite side of the fresh air outlet.

[0041] The second baffle also has a three-layer structure, and a second opening is provided on the middle layer of the three-layer structure. Specifically, the top layer of the second baffle is an arc-shaped structure that bulges upward (i.e., toward the water flow hole side), and the top layer can be higher than the height of the air chamber sheet metal. The middle layer of the second baffle is flush with the air chamber sheet metal, and a second opening is provided on the middle layer. The bottom layer uses a soft material to prevent interference with the air chamber sheet metal, and the soft material includes but is not limited to rubber, foam plastic, and polymer material.

[0042] The difference between the second baffle and the first baffle lies mainly in the different opening positions. Since the second baffle is arranged on the opposite side of the fresh air inlet, the risk of water splashing into the fresh air inlet from the opposite side is relatively small. Therefore, the second baffle can be provided with a second opening on the middle layer. On the one hand, it can prevent the water level in the air chamber from being too high. On the other hand, it can increase the strength when wiping water and improve the drainage efficiency.

[0043] In actual applications, the first baffle can be set on both the side of the fresh air outlet and the side opposite to the fresh air outlet, or the first baffle can be set on one side of the fresh air outlet and the second baffle can be set on the side opposite to the fresh air outlet. This application does not impose any restrictions on this.

[0044] Both the first baffle and the second baffle can slide back and forth along the slide rail below the middle water flow hole of the ventilation cover and above the water outlet of the air chamber, and can quickly transport the water falling from the middle water flow hole to above the water outlet of the air chamber to improve drainage efficiency.

[0045] In some embodiments of the present application, the vehicle may further include a wiper for wiping water from the center of the air chamber bottom plate (below the middle water outlet) to both sides (above the air chamber water outlet). Specifically, wipers may be provided on the left and right sides of the air chamber, respectively, and the wipers on both sides have the same step length when wiping water.

[0046] Specifically, the above-mentioned vehicle air conditioner waterproofing method may include the following steps S101 to S102.

[0047] Step S101, obtaining a first water level height of the air chamber, a first fresh air outlet height of the vehicle air conditioner, and a water content of the first fresh air outlet.

[0048] The first water level of the air chamber may refer to the height of the water surface in the air chamber relative to the bottom plate, which may be measured by a liquid level sensor at the bottom of the air chamber. Considering the uneven bottom of the air chamber, liquid level sensors may be arranged at multiple locations at the bottom of the air chamber, and the average value of the liquid level collected by all liquid level sensors may be taken as the first water level.

[0049] The height of the first fresh air outlet of the car air conditioner refers to the height of the fresh air outlet relative to the base plate, which is information that can be obtained in advance based on the vehicle model and its structure.

[0050] The moisture content of the first fresh air outlet refers to the moisture content around the fresh air outlet, which can be measured by a humidity sensor at the fresh air outlet position.

[0051] Step S102, controlling the baffle to slide on the slide rail according to the comparison result between the first water level height and the first fresh air inlet height, and the water content of the first fresh air inlet.

[0052] It is understandable that the comparison result of the first water level height and the first fresh air outlet height can reflect the height difference between the air chamber water level and the fresh air outlet, thereby reflecting the water ingress risk of the vehicle air conditioner. The water content of the first fresh air outlet reflects the water content around the fresh air outlet, indicating whether the fresh air outlet has or is about to have water ingress problems.

[0053] According to the comparison result of the first water level height and the first fresh air outlet height, as well as the water content of the first fresh air outlet, the baffle can be controlled to slide on the slide rail. Thus, when there may be a water ingress problem, the baffle can be controlled to slide back and forth along the slide rail below the middle water flow hole of the ventilation cover and above the air chamber outlet. The water flowing into the middle water flow hole can be discharged from the air chamber outlet in time.

[0054] In an embodiment of the present application, by obtaining a first water level height of the air chamber, a first fresh air outlet height of the vehicle air conditioner and a water content of the first fresh air outlet, the first water level height, the first fresh air outlet height and the water content of the first fresh air outlet can reflect the current risk of water ingress. According to the comparison result of the first water level height and the first fresh air outlet height, and the water content of the first fresh air outlet, the baffle is controlled to slide back and forth on the slide rail below the middle water flow hole of the ventilation cover and above the water outlet of the air chamber. When there is a risk of water ingress, the water falling into the middle water flow hole can be transported to the water outlet, thereby increasing the drainage efficiency, thereby controlling the water level of the air chamber below the fresh air outlet and preventing water from entering the air conditioner.

[0055] In some embodiments of the present application, Figure 6 As shown, according to the comparison result between the first water level height and the first fresh air outlet height, and the water content of the first fresh air outlet, controlling the baffle to slide on the slide rail may include: step S601 to step S603.

[0056] Step S601, if the first water level is less than or equal to the first fresh air outlet height, and the water content of the first fresh air outlet is less than or equal to the first water content threshold, the baffle is controlled to maintain the current state.

[0057] In the implementation of the present application, the baffle can be provided with different speed gears, and the sliding speeds between different speed gears are different. Specifically, the sliding speed of the baffle can be divided into two gears, namely the first speed gear and the second speed gear, and the sliding speed of the second speed gear is greater than the sliding speed of the first speed gear. For example, the first speed gear is 30 times of going back and forth between the middle water flow hole of the ventilation cover and the water outlet of the air chamber in 1 minute, and the second speed gear is 60 times of going back and forth between the middle water flow hole of the ventilation cover and the water outlet of the air chamber in 1 minute.

[0058] Specifically, if the first water level is less than or equal to the first fresh air outlet height, and the first fresh air outlet water content is less than or equal to the first water content threshold, it means that the current air chamber water level has not reached the fresh air outlet height, and the water content around the fresh air outlet is low, and the baffle can be controlled to maintain the current state. The current state indicates the current operating state of the baffle. When the vehicle is just started, the current state is the stopped state.

[0059] For different water level heights, different first water content thresholds can be set, and the first water content threshold is positively correlated with the water level height. For example, when the first water level height is less than or equal to 2 / 3 of the fresh air outlet height, the first water content threshold can be set to 50%. When the first water level height is greater than 2 / 3 of the fresh air outlet height, the first water content threshold can be set to 60%.

[0060] Step S602: If the first water level is less than or equal to the first fresh air outlet height, and the water content of the first fresh air outlet is greater than the first water content threshold, the baffle is controlled to slide according to the corresponding speed gear.

[0061] Specifically, if the first water level is less than or equal to the first fresh air outlet height, and the water content of the first fresh air outlet is greater than the first water content threshold, it means that the current air chamber water level has not reached the fresh air outlet height, but the water content around the fresh air outlet is high. At this time, the baffle needs to be controlled to slide according to the corresponding speed gear.

[0062] like Figure 7 As shown, controlling the baffle to slide according to the corresponding speed gear may include steps S701 to S703.

[0063] Step S701: if the first water level is less than or equal to the first water level threshold, the baffle is controlled to slide at a first speed gear.

[0064] The first water level threshold can be set according to actual conditions, for example, 1 / 3 of the first fresh air outlet height. If the first water level is less than or equal to the first water level threshold, it means that the air chamber water level is low, and the baffle can be controlled to slide according to the lower first speed gear.

[0065] Step S702: If the first water level is greater than the first water level threshold, and the moisture content of the first fresh air outlet is less than or equal to the second moisture content threshold, the baffle is controlled to slide at the first speed gear.

[0066] If the first water level height is greater than the first water level height threshold, and the water content of the first fresh air outlet is less than or equal to the second water content threshold, it means that the water content of the fresh air outlet is within a safe level and the water level in the air chamber has a certain height. At this time, it is necessary to pay special attention to the water level in the air chamber, and the baffle can be controlled to slide at a lower first speed gear.

[0067] In addition, when the first water level is greater than the first water level threshold and the water content of the first fresh air outlet is less than or equal to the second water content threshold, it may also include: re-obtaining the second water level of the air chamber after the baffle slides at the first speed gear for a first preset time period; and readjusting the speed gear when the baffle slides according to the second water level.

[0068] Specifically, the water level of the air chamber can be re-detected after the first preset time. Based on the second water level, if the second water level is lower than the first water level, the damper is controlled to maintain the current gear. Otherwise, the damper is controlled to increase the speed gear. After the first preset time is re-run, the third water level is detected again. If the third water level is lower than the first water level, the damper is controlled to maintain the current gear. Otherwise, the vehicle air conditioner is controlled to enter the internal circulation mode and continue to monitor the water level and the water content of the fresh air outlet. Therefore, the water level of the air chamber can be paid attention to and the speed gear can be adjusted in time.

[0069] Step S703: If the first water level is greater than the first water level threshold, and the water content of the first fresh air outlet is greater than the second water content threshold, the baffle is controlled to slide at the second speed gear.

[0070] If the first water level height is greater than the first water level height threshold, and the water content of the first fresh air outlet is greater than the second water content threshold, it means that the water content of the fresh air outlet exceeds the safety level. At this time, the baffle needs to be controlled to slide according to the higher second speed gear to improve drainage efficiency.

[0071] It should be noted that the second moisture content threshold is greater than the first moisture content threshold and can be set according to actual conditions. Similarly, different second moisture content thresholds can be set for different water level heights, and the second moisture content threshold is positively correlated with the water level height. For example, when the first water level height is less than or equal to 2 / 3 of the fresh air outlet height, the second moisture content threshold can be set to 60%. When the first water level height is less than or equal to 2 / 3 of the fresh air outlet height, the second moisture content threshold can be set to 80%.

[0072] Furthermore, when the first water level is greater than the first water level threshold, and the water content of the first fresh air outlet is greater than the second water content threshold, at least one of the following items may also be included:

[0073] 1. Control the outer baffle of the fresh air outlet of the vehicle air conditioner to move up to increase the height of the fresh air outlet of the vehicle air conditioner. Thus, the first water level can be lower than the height of the second fresh air outlet after the increase, reducing the risk of water ingress.

[0074] 2. Control the vehicle air conditioner to enter the internal circulation mode. It is understandable that when the vehicle air conditioner is in the external circulation mode, water in the air chamber is easily drawn into the passenger compartment from the fresh air outlet due to the effect of fresh air. After the vehicle air conditioner enters the internal circulation mode, the risk of water in the air chamber drawing into the passenger compartment from the fresh air outlet due to the effect of fresh air can be reduced.

[0075] In addition, when the first water level height is greater than the first water level height threshold and the water content of the first fresh air outlet is greater than the second water content threshold, it may also include: after the baffle slides at the second speed gear for a second preset time period, re-obtaining the water content of the second fresh air outlet of the vehicle air conditioner; and readjusting the speed gear when the baffle slides according to the water content of the second fresh air outlet.

[0076] Specifically, the water content of the fresh air outlet can be re-detected after the second preset time. According to the second fresh air outlet water content, if the second fresh air outlet water content is lower than the first fresh air outlet water content, the baffle is controlled to be lowered. Otherwise, the vehicle air conditioner is controlled to enter the internal circulation mode and continue to monitor the water level and the water content of the fresh air outlet. Thus, the water content of the fresh air outlet can be paid attention to and the speed gear can be adjusted in time.

[0077] Step S603: if the first water level is greater than the first fresh air outlet height, the baffle is controlled to slide at the highest speed gear.

[0078] Specifically, if the first water level is greater than the first fresh air outlet height, it means that water has entered the air and the baffle needs to be controlled to slide at the highest speed, such as the second speed, to drain water with the highest efficiency.

[0079] Similarly, in some embodiments of the present application, when the first water level is greater than the first fresh air outlet height, at least one of the following may also be included:

[0080] 1. Control the outer baffle of the fresh air outlet of the car air conditioner to move up to increase the height of the fresh air outlet of the car air conditioner.

[0081] 2. Control the vehicle air conditioner to enter the internal circulation mode.

[0082] In addition, after the baffle is controlled to slide at the highest speed gear, the method may further include: after the baffle slides at the highest speed gear for a third preset time, re-obtaining the second water level of the air chamber; if the second water level is reduced, maintaining the highest speed gear. If the second water level is not reduced, outputting a prompt message to warn of the water inflow state.

[0083] In some embodiments of the present application, the speed level of the baffle when sliding is positively correlated with the height ratio. The height ratio is the ratio between the water level of the air chamber and the height of the fresh air outlet of the vehicle air conditioner. In other words, the closer the water level of the air chamber is to the height of the fresh air outlet, the higher the speed level of the baffle when sliding should be, so as to achieve the effect of rapid drainage.

[0084] The following example illustrates this:

[0085] Case 1: when the first water level height h is less than 1 / 3 of the first fresh air outlet height H, the water content δ of the first fresh air outlet is determined;

[0086] 1-a. When the moisture content of the first fresh air outlet δ≤50%, keep the current state unchanged;

[0087] 1-b. When the moisture content of the first fresh air outlet δ>50%, the control baffle slides according to the first speed gear. After running for 10 minutes, continue to judge the moisture content of the second fresh air outlet; if the moisture content of the second fresh air outlet δ≤50%, keep running in the current state. If the moisture content of the second fresh air outlet δ>50%, the speed gear of the control baffle is increased to the second speed gear.

[0088] Case 2: when 1 / 3 of the first fresh air outlet height H ≤ the first water level height h < 2 / 3 of the first fresh air outlet height H, the water content δ of the first fresh air outlet is determined;

[0089] 2-a. When the moisture content of the first fresh air outlet is δ≤50%, the baffle is controlled to slide at the first speed gear;

[0090] 2-b. When 50%<the moisture content of the first fresh air outletδ≤60%, the baffle is controlled to slide at the first speed gear, and the second water level is detected after 10 minutes. If the second water level drops below 1 / 3H, the current mode is maintained; otherwise, the baffle is controlled to slide at the second speed gear, and the operation is continued for 10 minutes. The water level is detected again. If the new water level is ≤1 / 3H, the current mode is maintained. If the new water level is>1 / 3H, the vehicle air conditioner is controlled to enter the internal circulation mode, the baffle continues to slide to drain water, and the water level and the moisture content of the fresh air outlet are continuously monitored.

[0091] 3-c. When the moisture content of the first fresh air outlet δ>60%, the baffle is controlled to slide at the second speed gear. After running for 10 minutes, the moisture content of the second fresh air outlet is detected. If the moisture content of the second fresh air outlet is ≤50%, execute according to the above 2-a. If 50%<δ≤60%, execute according to the above 2-b. If δ>60%, the vehicle air conditioner is controlled to enter the internal circulation mode, the baffle continues to slide to drain water, and the water level and the moisture content of the fresh air outlet are continuously monitored.

[0092] Case 3: when 2 / 3 of the first fresh air outlet height H ≤ the first water level height h < the first fresh air outlet height H, the water content δ of the first fresh air outlet is determined;

[0093] 3-a. When the moisture content of the first fresh air outlet δ is less than 60%, the baffle is controlled to slide according to the second speed gear; it can be understood that since the height ratio corresponding to situation three (≥2 / 3) is higher than that of situation two (<2 / 3), the speed gear is higher when the moisture content of the first fresh air outlet δ is less than 60%.

[0094] 3-b. When 60%≤the moisture content of the first fresh air outletδ≤80%, the baffle is controlled to slide at the second speed gear, and the moisture content of the second fresh air outlet is detected after 10 minutes. If the moisture content of the second fresh air outlet drops below 60%, the above strategy 3-a is executed; if 60%≤the moisture content of the first fresh air outletδ≤80%, the vehicle air conditioner is controlled to enter the internal circulation mode, the baffle continues to slide to drain water, and the water level and the moisture content of the fresh air outlet are continuously monitored.

[0095] 3-c. When the moisture content of the first fresh air outlet δ>80%, the control baffle slides at the second speed gear, controls the outer baffle of the fresh air outlet of the vehicle air conditioner to move up 50%, and the vehicle air conditioner enters the internal circulation mode. After running for 10 minutes, the second water level is detected. If the second water level drops below 2 / 3H, it is controlled according to situation 2. If the second water level does not change significantly, the current state is maintained unchanged, and the water level and the moisture content of the fresh air outlet are continuously monitored. If the second water level rises further and exceeds the fresh air outlet height, it is executed according to the following situation 4.

[0096] Case four, when the first water level height h ≥ the first fresh air outlet height H, the baffle is controlled to slide according to the second speed gear, the outer baffle of the fresh air outlet of the vehicle air conditioner is controlled to move up 50%, and the vehicle air conditioner enters the internal circulation mode. After 10 minutes of execution, pay attention to whether the second water level height has obvious changes. If the second water level height decreases, the current state remains unchanged; if the second water level height increases, it means that the rainfall is heavy at this time, or the vehicle has entered a section with deep water, indicating that the fresh air outlet of the air conditioner has been flooded, and ask whether rescue services are needed.
