Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning technology, specifically providing an automotive roof-mounted air conditioning system and vehicle. Background Technology

[0002] The roof-mounted integrated parking air conditioner is a very convenient in-vehicle air conditioning device. It is installed on the roof of the vehicle and can regulate the temperature inside the vehicle, providing a more comfortable driving environment for the driver.

[0003] In existing technology, roof-mounted integrated parking air conditioners are usually installed in the original sunroof opening, which causes the original sunroof air intake function of the vehicle to be lost. When the external environment of the vehicle is relatively comfortable, fresh and cool air cannot be introduced through the sunroof, affecting the user experience. Utility Model Content

[0004] The present invention aims to solve the above-mentioned technical problems to at least a certain extent, that is, to solve the problem that the existing roof-mounted integrated parking air conditioner cannot introduce fresh air from outside through the sunroof, resulting in a poor user experience.

[0005] In a first aspect, this utility model provides a vehicle roof-mounted air conditioning system, which is installed in the sunroof opening of a vehicle. The vehicle roof-mounted air conditioning system includes: a temperature regulating component; an air duct component having an inner air duct and an outer air duct, wherein the temperature regulating component is used to heat or cool the airflow entering the inner air duct, the inner air duct is used to return the airflow heated or cooled by the temperature regulating component to the passenger compartment, and the outer air duct is used to transport airflow from outside the vehicle to the passenger compartment; an air duct valve for opening or closing the outer air duct; and an adjusting component configured to adjust the opening degree of the air duct valve to adjust the airflow rate flowing into the passenger compartment through the outer air duct.

[0006] In the preferred embodiment of the above-mentioned vehicle roof-mounted air conditioning system, the inlet end of the external air duct forms a first air inlet, the air duct valve is disposed at the first air inlet and is used to open or close the first air inlet, and the adjusting component is drivenly connected to the air duct valve to drive the air duct valve to move relative to the air duct assembly, thereby adjusting the opening degree of the air duct valve.

[0007] In the preferred embodiment of the above-mentioned vehicle roof-mounted air conditioning system, the vehicle roof-mounted air conditioning system further includes a filter component for filtering the airflow in the inner air duct and / or the outer air duct; and / or, the vehicle roof-mounted air conditioning system further includes an air guide component for introducing air from outside the vehicle into the outer air duct.

[0008] In the preferred embodiment of the above-mentioned vehicle roof-mounted air conditioning system, the filter component includes a first filter screen and a second filter screen. The first filter screen is disposed in the outer air duct and is used to filter the airflow in the outer air duct. The second filter screen is disposed in the inner air duct and is used to filter the airflow in the inner air duct.

[0009] In the preferred embodiment of the above-mentioned vehicle roof-mounted air conditioning system, the vehicle roof-mounted air conditioning system further includes a fan, which is used to drive the airflow in the inner air duct and the outer air duct to flow into the cockpit; and / or, the vehicle roof-mounted air conditioning system further includes a flow velocity detection component, which is used to detect the airflow velocity in the outer air duct.

[0010] In the preferred embodiment of the above-mentioned vehicle roof-mounted air conditioning system, the vehicle roof-mounted air conditioning system further includes a vehicle speed detection component, which is used to detect the speed of the vehicle. The vehicle speed detection component is communicatively connected to the fan so as to selectively adjust the start and stop of the fan according to the vehicle speed detected by the vehicle speed detection component.

[0011] In the preferred embodiment of the above-mentioned vehicle roof-mounted air conditioning system, the flow velocity detection component is communicatively connected to the adjustment component so as to adjust the opening of the air duct valve according to the airflow velocity detected by the flow velocity detection component; and / or, the fan has at least two fan speed settings, and the flow velocity detection component is communicatively connected to the fan so as to adjust the fan speed according to the airflow velocity detected by the flow velocity detection component.

[0012] In the preferred embodiment of the above-mentioned vehicle roof-mounted air conditioning system, the inner air duct and the outer air duct are connected to the driver's cabin through the air outlet duct, wherein: the fan is installed in the air outlet duct; when the vehicle is in internal circulation mode, the fan drives the airflow in the inner air duct to flow into the driver's cabin; when the vehicle is in external circulation mode, the fan drives the airflow in the outer air duct to flow into the driver's cabin; and / or, the temperature regulating component includes a compressor, a condenser, and an evaporator, the compressor, the condenser, and the evaporator being sequentially connected to form a refrigerant circuit, wherein the evaporator is installed in the inner air duct or the air outlet duct.

[0013] In the preferred embodiment of the above-mentioned vehicle roof-mounted air conditioning system, the fan has a first working mode and a second working mode. When the fan is in the first working mode, the airflow outside the vehicle can be transported to the cabin through the external air duct. When the fan is in the second working mode, the airflow inside the cabin can be transported to the outside of the vehicle through the external air duct.

[0014] In a second aspect, the present invention also provides a vehicle, the vehicle including any of the above-described vehicle roof-mounted air conditioning systems.

[0015] When the above-mentioned preferred technical solution is adopted, the airflow heated or cooled by the temperature regulation component in the cockpit can be sent back to the cockpit through the internal air duct, thereby realizing the internal circulation of airflow in the cockpit. On the other hand, the airflow outside the vehicle can also be introduced into the cockpit through the external air duct, which not only saves energy but also improves the driving and riding comfort of the occupants. It avoids the problem of not being able to introduce fresh air from outside the vehicle into the cockpit due to the installation of a roof-mounted air conditioner at the sunroof opening. In addition, by setting up a flow regulation component, the airflow into the cockpit through the external air duct can be adjusted, thereby adjusting the air intake volume according to the user's actual needs and greatly improving the user experience.

[0016] Furthermore, compared to placing the air duct valve inside the external air duct, placing the air duct valve at the first air inlet can prevent external dust, rain, and snow from entering the external air duct when the vehicle is not in external circulation mode, thereby keeping the external air duct cleaner and further improving the user experience.

[0017] Furthermore, by incorporating filtering components, the airflow within the internal and / or external air ducts can be filtered, ensuring that the airflow entering the cockpit is clean air, thereby improving the air quality within the cockpit and further enhancing the user experience.

[0018] Furthermore, by configuring the vehicle speed detection component to communicate with the fan, the fan's operation can be selectively adjusted based on the vehicle speed. When the vehicle speed is below a preset value, the fan is activated because the collision wind utilization is low, driving the airflow outside the vehicle to flow into the cabin through the external air duct. When the vehicle speed is above the preset value, the airflow outside the vehicle can flow into the cabin through the external air duct without activating the fan, thus achieving air exchange inside the vehicle and reducing energy consumption.

[0019] Furthermore, by configuring the flow rate detection component to communicate with the adjustment component, the opening of the air duct valve can be adjusted according to the airflow speed detected by the flow rate detection component. On the one hand, this avoids excessive airflow caused by a large airflow speed in the external air duct and an excessively large opening of the air duct valve. On the other hand, it avoids insufficient airflow from the outside of the vehicle to the cabin caused by a small airflow speed in the external air duct and an excessively small opening of the air duct valve, thereby further improving the user's driving experience.

[0020] Furthermore, by configuring the flow rate detection component to communicate with the fan, the fan speed can be adjusted according to the airflow velocity in the external air duct. When the airflow velocity is high, the fan is adjusted to a low speed setting, which not only saves energy but also prevents excessive wind speed from affecting the user's driving experience. When the airflow velocity is low, the fan is adjusted to a high speed setting, which prevents the fan speed from being too low and failing to effectively introduce fresh air from outside the vehicle into the cabin, further enhancing the user experience.

[0021] Furthermore, by setting the fan to have a first working mode and a second working mode, on the one hand, the fan can drive the airflow outside the vehicle to flow into the cabin, thereby introducing fresh air from outside the vehicle into the cabin. On the other hand, the fan can also drive the airflow inside the cabin to flow outside the vehicle, thereby expelling stale air from the cabin, achieving ventilation and further improving the user experience.

[0022] Furthermore, the vehicle provided by this utility model, based on the aforementioned vehicle roof-mounted air conditioning system, possesses the beneficial effects of the aforementioned vehicle roof-mounted air conditioning system. Compared to existing vehicles, the vehicle of this utility model can introduce fresh outside air into the cabin, resulting in a more comfortable driving experience and greater energy savings.

[0032] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0033] It should be noted that in the description of this utility model, terms such as "upper," "lower," "inner," and "outer," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0034] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] In light of the problem mentioned in the background art that existing roof-mounted integrated parking air conditioners cannot introduce fresh air from outside through the sunroof, resulting in a poor user experience, this utility model provides a vehicle roof-mounted air conditioning system that not only introduces fresh air from outside into the driver's cabin, but also adjusts the air intake volume according to user needs, greatly improving the user experience.

[0036] Specifically, such as Figure 1As shown, the vehicle roof-mounted air conditioning system of this utility model is installed in the sunroof opening of vehicle 1. The vehicle roof-mounted air conditioning system includes a temperature regulating component 21, an air duct component, an air duct valve 2212, and an adjusting component 241.

[0037] like Figures 2 to 4 As shown, the air duct assembly has an inner air duct 222 and an outer air duct 221. The temperature regulating component 21 is used to heat or cool the airflow entering the inner air duct 222. The inner air duct 222 is used to send the airflow heated or cooled by the temperature regulating component 21 back into the cockpit 10. The outer air duct 221 is used to transport the airflow outside the vehicle 1 to the cockpit 10.

[0038] The air duct valve 2212 is used to open or close the external air duct 221, and the adjusting member 241 is configured to adjust the opening degree of the air duct valve 2212 in order to adjust the air flow rate through the external air duct 221 to the cockpit 10.

[0039] With this configuration, on the one hand, the airflow heated or cooled by the temperature regulating component 21 inside the cockpit 10 can be sent back to the cockpit 10 through the internal air duct 222, thereby achieving internal circulation of airflow inside the cockpit 10. On the other hand, the airflow outside the vehicle 1 can also be introduced into the cockpit 10 through the external air duct 221. This not only saves energy but also improves the driving and riding comfort of the occupants, avoiding the problem of not being able to introduce fresh air from outside the vehicle 1 into the cockpit 10 due to the installation of a roof-mounted air conditioner at the sunroof opening of the vehicle 1. In addition, by setting up a flow regulating component, the airflow into the cockpit 10 through the external air duct 221 can be adjusted, thereby adjusting the air intake volume according to the actual needs of the user, greatly improving the user experience.

[0040] It should be noted that this utility model does not limit the specific type of vehicle 1, as long as vehicle 1 has a sunroof opening and a roof-mounted air conditioning system is installed at the sunroof opening. For example, vehicle 1 can be a truck, or vehicle 1 can be a van, etc. Such adjustments and changes to the specific type of vehicle 1 do not deviate from the principle and scope of this utility model and should be included within the protection scope of this utility model.

[0041] It should be noted that, in practical applications, those skilled in the art do not impose any limitations on the specific location of the duct valve 2212. For example, the duct valve 2212 can be placed inside the external duct 221, or it can be placed at the inlet end of the external duct 221, etc. Such adjustments and changes to the specific location of the duct valve 2212 do not deviate from the principle and scope of this utility model and should be included within the protection scope of this utility model.

[0042] Preferably, such as Figures 2 to 4 As shown, the inlet end of the external air duct 221 forms a first air inlet 2211. The air duct valve 2212 is disposed at the first air inlet 2211 and is used to open or close the first air inlet 2211. The adjusting member 241 is drivenly connected to the air duct valve 2212 so as to drive the air duct valve 2212 to move relative to the air duct assembly, thereby adjusting the opening degree of the air duct valve 2212.

[0043] With this configuration, compared to placing the air duct valve 2212 inside the external air duct 221, placing the air duct valve 2212 inside the first air inlet 2211 can prevent external dust, rain, and snow from entering the external air duct 221 when the vehicle 1 is not in external circulation mode, thereby making the external air duct 221 cleaner and further improving the user experience.

[0044] It should be noted that, in practical applications, those skilled in the art can configure the duct valve 2212 to be rotatably connected relative to the duct assembly to adjust the opening of the duct valve 2212, or the duct valve 2212 can be slidably connected relative to the duct assembly to adjust the opening of the duct valve 2212, or the duct valve 2212 can be configured in any other possible form, etc. Such flexible adjustments and changes do not deviate from the principle and scope of this utility model and should be included within the protection scope of this utility model.

[0045] Preferably, the duct valve 2212 is configured to be rotatably connected relative to the duct assembly to adjust the opening degree of the duct valve 2212.

[0046] With this configuration, when the air duct valve 2212 opens the external air duct 221, the air duct valve 2212 can guide the airflow, allowing the airflow outside the vehicle 1 to enter the external air duct 221 more smoothly through the first air inlet 2211.

[0047] It should be noted that, in practical applications, those skilled in the art do not impose any limitations on the specific configuration type of the adjusting component 241, as long as it can drive the duct valve 2212 to rotate relative to the duct assembly. For example, the adjusting component 241 can be configured as a motor, with the motor's output end connected to the duct valve 2212 for driving. Alternatively, the adjusting component 241 can be configured as a structure of a motor and gears, with the motor's output end connected to the duct valve 2212 via gears, and so on. Such adjustments and changes to the specific configuration type of the adjusting component 241 do not deviate from the principles and scope of this utility model and should all be included within the protection scope of this utility model.

[0048] For example, the adjusting member 241 is configured as a motor, and the output end of the motor is drivenly connected to the air duct valve 2212.

[0049] Preferably, such as Figures 2 to 4 As shown, the vehicle roof-mounted air conditioning system of this utility model also includes an air guide component 23, which is used to introduce the air from outside the vehicle 1 into the external air duct 221 through the first air inlet 2211.

[0050] By setting the air guide component 23, the wind outside the vehicle 1 can enter the external air duct 221 more smoothly, thereby more effectively introducing the wind outside the vehicle 1 into the cockpit 10.

[0051] It should be noted that this utility model does not impose any restrictions on the specific arrangement of the inner air duct 222 and the outer air duct 221, as long as the heated or cooled airflow inside the driver's cabin 10 can be sent back into the driver's cabin 10 through the inner air duct 222, and the airflow outside the vehicle 1 can be transported into the driver's cabin 10 through the outer air duct 221.

[0052] In one specific embodiment, the inner air duct 222 and the outer air duct 221 respectively deliver airflow to the cockpit 10 (not shown in the figure) through different air outlets 2231. That is, the air duct assembly has a first air outlet 2231 and a second air outlet 2231. The outlet end of the outer air duct 221 is connected to the first air outlet 2231. The airflow outside the vehicle 1 flows from the outer air duct 221 to the cockpit 10 through the first air outlet 2231. The outlet end of the inner air duct 222 is connected to the second air outlet 2231. The airflow inside the cockpit 10 after being heated or cooled flows from the inner air duct 222 to the cockpit 10 through the second air outlet 2231.

[0053] In another specific embodiment, such as Figures 2 to 4 As shown, the inner air duct 222 and the outer air duct 221 deliver airflow to the cockpit 10 through the same air outlet 2231. That is, the air duct assembly has an air outlet 2231, the inlet end 221 of the outer air duct forms a first air inlet 2211, the inlet end 222 of the inner air duct forms a second air inlet 2221, and the outlet ends of the outer air duct 221 and the inner air duct 222 are both connected to the air outlet 2231. The airflow outside the vehicle 1 flows from the outer air duct 221 through the air outlet 2231 to the cockpit 10, and the airflow inside the cockpit 10 after being heated or cooled flows into the cockpit 10 through the air outlet 2231.

[0054] Preferably, the air duct assembly also has an air outlet 2231, which is connected to the cockpit 10, and the outlet end of the outer air duct 221 and the outlet end of the inner air duct 222 are both connected to the air outlet 2231.

[0055] Preferably, such as Figures 2 to 4 As shown, the vehicle roof-mounted air conditioning system of this utility model also includes a filter component, which is used to filter the airflow in the inner air duct 222 and / or the outer air duct 221.

[0056] By setting up a filter component, the airflow in the inner air duct 222 and / or the outer air duct 221 can be filtered, so that the airflow entering the cockpit 10 is clean air, improving the air quality in the cockpit 10 and further enhancing the user experience.

[0057] It should be noted that, in practical applications, those skilled in the art can configure the filter component to filter only the airflow in the inner air duct 222, or the filter component to filter only the airflow in the outer air duct 221, or the filter component to filter the airflow in both the inner air duct 222 and the outer air duct 221, etc. Such flexible adjustments and changes do not deviate from the principles and scope of this utility model and should all be included within the protection scope of this utility model.

[0058] Preferably, the filter element is capable of filtering the airflow within the inner air duct 222 and the outer air duct 221.

[0059] In one specific embodiment, such as Figures 2 to 4 As shown, the filter component includes a first filter screen 2213 and a second filter screen 2222. The first filter screen 2213 is disposed in the external air duct 221 and is used to filter the airflow in the external air duct 221. The second filter screen 2222 is disposed in the internal air duct 222 and is used to filter the airflow in the internal air duct 222.

[0060] When the vehicle is in external circulation mode, the airflow in the external air duct 221 is filtered by the first filter screen 2213 and then delivered to the driver's cabin 10. When the vehicle is in internal circulation mode, the airflow in the internal air duct 222 is filtered by the second filter screen 2222 and then delivered to the driver's cabin 10.

[0061] In another specific embodiment, the air duct assembly further includes an air outlet duct 223, the outlet end of the inner air duct 222 and the outlet end of the outer air duct 221 are both connected to the first end of the air outlet duct 223, and the second end of the air outlet duct 223 is connected to the cockpit 10. The filter component is disposed inside the air outlet duct 223 (not shown in the figure).

[0062] It should be noted that, in practical applications, those skilled in the art can configure the external air duct 221 to allow airflow from outside the vehicle 1 to flow into the driver's cabin 10 through the external air duct 221 during the vehicle's operation. Alternatively, a fan 224 can be used to allow airflow from outside the vehicle 1 to flow into the driver's cabin 10 through the external air duct 221, etc. Such flexible adjustments and changes do not deviate from the principles and scope of this utility model and should be included within the protection scope of this utility model.

[0063] Preferably, such as Figures 2 to 4As shown, the vehicle roof-mounted air conditioning system of this utility model also includes a fan 224, which is used to drive the airflow in the inner air duct 222 and / or the outer air duct 221 to flow into the cockpit 10.

[0064] With this setup, when vehicle 1 is parked, the airflow outside vehicle 1 can be introduced into the cockpit 10 through the external air duct 221 by starting the fan 224, further enhancing the user experience.

[0065] It should be noted that, in practical applications, those skilled in the art can respectively install a first fan and a second fan in the outer air duct 221 and the inner air duct 222. The first fan is used to drive the airflow in the outer air duct 221 to flow into the driver's cabin 10, and the second fan is used to drive the airflow in the inner air duct 222 to flow into the driver's cabin 10. Alternatively, the inner air duct 222 and the outer air duct 221 can be configured to connect with the driver's cabin 10 through the air outlet duct 223, with the fan 224 installed in the air outlet duct 223. In the vehicle's internal circulation mode, the fan 224 drives the airflow in the inner air duct 222 to flow into the driver's cabin 10. In the vehicle's external circulation mode, the fan 224 drives the airflow in the outer air duct 221 to flow into the driver's cabin 10, and so on. Such flexible adjustments and changes do not deviate from the principles and scope of this utility model and should all be included within the protection scope of this utility model.

[0066] Preferably, such as Figures 2 to 4 As shown, the inner air duct 222 and the outer air duct 221 are configured to connect with the cockpit 10 through the air outlet duct 223. The fan 224 is installed in the air outlet duct 223. When the vehicle is in the internal circulation mode, the fan 224 drives the airflow in the inner air duct 222 to flow into the cockpit 10. When the vehicle is in the external circulation mode, the fan 224 drives the airflow in the outer air duct 221 to flow into the cockpit 10.

[0067] With this setup, only one fan 224 is needed to direct the airflow from the inner air duct 222 and the outer air duct 221 to the cockpit 10, thereby reducing the number of fans 224 required and lowering the weight and cost of the vehicle roof-mounted air conditioning system.

[0068] It should also be noted that, in practical applications, this utility model does not limit the specific configuration type of the temperature regulating component 21. For example, the temperature regulating component 21 can be configured to include a compressor 211, an evaporator 212, and a condenser 213, with the compressor 211, evaporator 212, and condenser 213 connected in sequence to form a refrigerant circuit. Alternatively, the temperature regulating component 21 can be configured as a heating element that can heat the airflow in the inner air duct 222. Or, the temperature regulating component 21 can be configured as a heat exchange element that can exchange heat with the airflow in the inner air duct 222, and so on. Such adjustments and changes to the specific configuration type of the temperature regulating component 21 do not deviate from the principle and scope of this utility model and should all be included within the protection scope of this utility model.

[0069] Preferably, such as Figure 5 As shown, the temperature control component 21 is configured to include a compressor 211, an evaporator 212 and a condenser 213. The compressor 211, evaporator 212 and condenser 213 are connected in sequence to form a refrigerant circuit. The evaporator 212 is used to heat or cool the airflow in the internal air duct 222.

[0070] It should be noted that those skilled in the art do not impose any restrictions on the specific location of the evaporator 212, as long as it can heat or cool the airflow in the inner air duct 222.

[0071] In one specific embodiment, the evaporator 212 is disposed within the inner air duct 222 and is used to heat or cool the airflow within the inner air duct 222.

[0072] In another specific embodiment, the evaporator 212 is disposed in the air outlet duct 223 and is used to heat or cool the airflow in the inner air duct 222 and / or the outer air duct 221.

[0073] Preferably, such as Figures 2 to 4 As shown, the evaporator 212 is disposed in the air outlet duct 223 and is used to heat or cool the airflow in the inner air duct 222 and / or the outer air duct 221.

[0074] In this way, not only can the airflow in the inner air duct 222 be heated or cooled, but the temperature regulation component 21 can also heat or cool the airflow in the outer air duct 221, further improving the user experience.

[0075] Preferably, such as Figure 6 As shown, the vehicle roof-mounted air conditioning system of this utility model also includes a vehicle speed detection component 242, which is used to detect the speed of the vehicle 1. The vehicle speed detection component 242 is communicatively connected to the fan 224 so as to selectively adjust the opening and closing of the fan 224 according to the vehicle speed detected by the vehicle speed detection component 242.

[0076] With this setting, the opening and closing of the fan 224 can be selectively adjusted according to the vehicle speed. When the vehicle speed is lower than the preset value, the fan 224 is activated because the collision wind utilization is low. This drives the airflow outside the vehicle 1 to flow into the driver's cabin 10 through the external air duct 221. When the vehicle speed is higher than the preset value, the collision wind of the vehicle 1 can be utilized, and the fan 224 does not need to be activated. The airflow outside the vehicle 1 can still flow into the driver's cabin 10 through the external air duct 221, thereby achieving air exchange inside the vehicle and reducing energy consumption.

[0077] Preferably, such as Figure 6 As shown, the vehicle roof-mounted air conditioning system of this utility model also includes a flow rate detection component 243, which is used to detect the airflow speed in the external air duct 221. The flow rate detection component 243 is communicatively connected to the adjustment component 241.

[0078] By setting the flow rate detection component 243, the airflow velocity in the external air duct 221 can be detected, so that the opening of the air duct valve 2212 can be adjusted according to the airflow velocity detected by the flow rate detection component 243. On the one hand, it can avoid the airflow being too large due to the high airflow velocity in the external air duct 221 and the excessive opening of the air duct valve 2212. On the other hand, it can avoid the airflow being too small due to the low airflow velocity in the external air duct 221 and the insufficient opening of the air duct valve 2212, which would prevent the fresh air outside the vehicle 1 from being effectively introduced into the cockpit 10, thereby further improving the user's driving experience.

[0079] It should be noted that in practical applications, the flow velocity detection component 243 can be set as a wind speed sensor, or it can be set as a pressure sensor, and the airflow speed can be detected by the pressure applied by the wind to the pressure sensor, etc. Such adjustments and changes to the specific setting type of the flow velocity detection component 243 do not deviate from the principle and scope of this utility model, and should all be included within the protection scope of this utility model.

[0080] For example, the flow velocity detection component 243 is a wind speed sensor.

[0081] It should be noted that in practical applications, the fan 224 can be set to have only one speed setting, or the fan 224 can be set to have at least two speed settings. The flow velocity detection component 243 is communicatively connected to the fan 224 so as to adjust the speed of the fan 224 according to the airflow velocity detected by the flow velocity detection component 243, etc. Such flexible adjustments and changes do not deviate from the principle and scope of this utility model and should be included within the protection scope of this utility model.

[0082] Preferably, such as Figure 6As shown, the fan 224 has at least two wind speed settings, and the flow velocity detection component 243 is communicatively connected to the fan 224 so as to adjust the wind speed of the fan 224 according to the airflow velocity detected by the flow velocity detection component 243.

[0083] With this setting, the fan speed of the fan 224 can be adjusted according to the airflow speed in the external air duct 221. When the airflow speed is high, the fan 224 is adjusted to a low speed setting, which not only saves energy but also prevents the wind speed from being too high and affecting the user's driving experience. When the airflow speed is low, the fan 224 is adjusted to a high speed setting, which prevents the fan speed of the fan 224 from being too low and failing to effectively introduce fresh air from outside the vehicle 1 into the cockpit 10, further improving the user experience.

[0084] It should be noted that, in practical applications, those skilled in the art can configure the fan 224 to only drive the airflow in the external air duct 221 to flow into the cockpit 10, or the fan 224 can be configured to have a first working mode and a second working mode. When the fan 224 is in the first working mode, the airflow outside the vehicle 1 can be transported to the cockpit 10 through the external air duct 221. When the fan 224 is in the second working mode, the airflow inside the cockpit 10 can be transported to the outside of the vehicle 1 through the external air duct 221, and so on. Such adjustments and changes to the specific working mode of the fan 224 do not deviate from the principle and scope of this utility model and should be included within the protection scope of this utility model.

[0085] Preferably, such as Figure 3 and Figure 4 As shown, the fan 224 has a first operating mode and a second operating mode. When the fan 224 is in the first operating mode (e.g....), Figure 3 As shown), the airflow outside the vehicle 1 can be delivered to the driver's cabin 10 through the external air duct 221, when the fan 224 is in the second operating mode (e.g. Figure 4 As shown), the airflow inside the cockpit 10 can be transported to the outside of the vehicle 1 through the external air duct 221.

[0086] With this configuration, on the one hand, the fan 224 can drive the airflow outside the vehicle 1 to the cockpit 10, thereby introducing fresh air from outside the vehicle 1 into the cockpit 10. On the other hand, the fan 224 can also drive the airflow inside the cockpit 10 to the outside of the vehicle 1, thereby expelling stale air from the cockpit 10, achieving ventilation, and further improving the user experience.

[0087] It should be noted that, in practical applications, this utility model does not impose any limitations on the specific driving method of the fan 224, which can both drive the airflow outside the vehicle 1 to be transported to the cab 10 through the external air duct 221 and drive the airflow inside the cab 10 to be transported to the outside of the vehicle 1 through the external air duct 221.

[0088] In one specific embodiment, the fan 224 is configured to rotate in both the forward and reverse directions. When the fan 224 is in the first working mode, it rotates in the forward direction and drives the airflow outside the vehicle 1 to flow into the cockpit 10. When the fan 224 is in the second working mode, it rotates in the reverse direction and drives the airflow inside the cockpit 10 to flow into the outside of the vehicle 1 through the external air duct 221.

[0089] In another specific embodiment, the blower 224 has a first fan and a second fan. When the blower 224 is in a first working mode, the first fan rotates and can drive the airflow outside the vehicle 1 to flow into the cockpit 10. When the blower 224 is in a second working mode, the second fan rotates and can drive the airflow inside the cockpit 10 to flow into the outside of the vehicle 1 through the external air duct 221.

[0090] Preferably, when the fan 224 is in the first working mode, the fan 224 rotates in the forward direction, and when the fan 224 is in the second working mode, the fan 224 rotates in the reverse direction.

[0091] In addition, this utility model also provides a vehicle 1, which includes any of the above-mentioned vehicle roof-mounted air conditioning systems.

[0092] Because the vehicle possesses the beneficial effects of the aforementioned roof-mounted air conditioning system, compared to existing vehicles, the vehicle of this utility model can introduce fresh outside air into the cabin, resulting in a more comfortable driving experience and greater energy savings.

[0093] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
