[0038] In the embodiments of this application, reference is made to Figures 1 to 4 This application also provides an automotive air conditioning device 100, which is applied to a heat pump air conditioning system, and the automotive air conditioning device 100 includes: a housing 110 and an air intake driver 120.

[0039] Specifically, the housing 110 includes an air inlet box 111 and an air distribution box 112 connected to each other. The air inlet box 111 is provided with a first air inlet cavity 1111 and a second air inlet cavity 1112 that are separated from each other. The air distribution box 112 is provided with a first air distribution cavity 1123 and a second air distribution cavity 1124 that are separated from each other. The first air distribution cavity 1123 is connected to the first air inlet cavity 1111 so that the gas in the first air inlet cavity 1111 can flow to the first air distribution cavity 1123. The second air distribution cavity 1124 is connected to the second air inlet cavity 1112 so that the gas in the second air inlet cavity 1112 can flow to the second air distribution cavity 1124. An air inlet driver 120 is installed in the air inlet box 111, and part of the air inlet driver 120 is located in the first air inlet cavity 1111, while the other part of the air inlet driver 120 is located in the second air inlet cavity 1112.

[0040] The air intake drive 120 is a blower, but is not limited to this.

[0041] Specifically, the air inlet box 111 is provided with a first air inlet 1113 and a second air inlet 1114. The first air inlet 1113 can selectively communicate with the first air inlet cavity 1111, and the first air inlet 1113 can selectively communicate with the second air inlet cavity 1112. That is, the first air inlet 1113 can be connected to the first air inlet cavity 1111 or not connected to the first air inlet cavity 1111, and the first air inlet 1113 can be connected to the second air inlet cavity 1112 or not connected to the second air inlet cavity 1112. The first air inlet 1113 is also connected to the external space and is used to introduce fresh air from outside. The second air inlet 1114 can selectively connect to the second air intake cavity 1112, and can also selectively connect to the first air intake cavity 1111. That is, the second air inlet 1114 can be connected to or not connected to the second air intake cavity 1112, and the second air inlet 1114 can be connected to or not connected to the first air intake cavity 1111. The second air inlet 1114 is also connected to the passenger compartment of the vehicle and is used to introduce air from inside the passenger compartment.

[0042] Understandably, the automotive air conditioning unit 100 in this application has an external circulation mode, an internal circulation mode, and an intermediate mode, and can be freely switched between the three modes.

[0043] When the car air conditioning unit 100 is in external circulation mode, the first air inlet 1113 is connected to the first air inlet cavity 1111 and the second air inlet cavity 1112, while the second air inlet 1114 is blocked, meaning it is not connected to either the first air inlet cavity 1111 or the second air inlet cavity 1112. The air intake driver 120 operates, and fresh external air flows from the first air inlet 1113 to the first air inlet cavity 1111 and the second air inlet cavity 1112, then from the first air inlet cavity 1111 to the first air distribution cavity 1123, and from the second air inlet cavity 1112 to the second air distribution cavity 1124. The fresh air located in the first air distribution cavity 1123 and the second air distribution cavity 1124 is then delivered to the car's passenger compartment. Because it is fresh air, this operating mode not only provides a fresh and comfortable environment for the driver and passengers but also prevents windows from fogging up and improves the car's defrosting efficiency.

[0044] When the car air conditioning unit 100 is in recirculation mode, the first air inlet 1113 is blocked, meaning it is not connected to the first air intake cavity 1111 or the second air intake cavity 1112. The second air inlet 1114 is connected to both the first air intake cavity 1111 and the second air intake cavity 1112. When the air intake driver 120 operates, air in the car's passenger compartment flows from the second air inlet 1114 to the first air intake cavity 1111 and the second air intake cavity 1112, then from the first air intake cavity 1111 to the first air distribution cavity 1123, and from the second air intake cavity 1112 to the second air distribution cavity 1124. The air located in the first air distribution cavity 1123 and the second air distribution cavity 1124 is then delivered to the car's passenger compartment. Since the air inside the car's passenger compartment remains almost constant, the original temperature inside the passenger compartment is maintained, reducing energy loss during air thermal management, improving the thermal management efficiency of the car's air conditioning unit 100, making the car's air conditioning unit 100 energy-saving and efficient, and at the same time improving the driving and riding comfort of the car's passengers.

[0045] When the vehicle air conditioning unit 100 is in the intermediate operating mode, the first air inlet 1113 is connected to the first air intake cavity 1111, but not to the second air intake cavity 1112. The second air inlet 1114 is connected to the second air intake cavity 1112, but not to the first air intake cavity 1111. The air intake driver 120 operates, and fresh air from outside flows from the first air inlet 1113 to the first air intake cavity 1111. Air in the vehicle's passenger compartment flows from the second air inlet 1114 to the second air intake cavity 1112. Fresh air then flows from the first air intake cavity 1111 to the first air distribution cavity 1123, and air in the vehicle's passenger compartment flows from the second air intake cavity 1112 to the second air distribution cavity 1124. The fresh air in the first air distribution cavity 1123 and the air in the second air distribution cavity 1124 are delivered to the vehicle's passenger compartment. This allows drivers and passengers to enjoy a fresh and comfortable environment, prevents windows from fogging up, and improves the car's defrosting efficiency. At the same time, it reduces energy loss during air thermal management, improves the thermal management efficiency of the car's air conditioning system 100, and makes the car's air conditioning system 100 more energy-efficient, while also improving the driving and riding comfort of the car's passengers.

[0046] This application controls the communication between the first air inlet 1113 and the first air inlet cavity 1111 and / or the second air inlet cavity 1112, and controls the communication between the second air inlet 1114 and the first air inlet cavity 1111 and / or the second air inlet cavity 1112, thereby controlling the automotive air conditioning unit 100 to freely switch between different operating modes, ensuring the ease of use of the automotive air conditioning unit 100 and facilitating its normal control. Simultaneously, this application can also control the internal and external circulation of the automotive air conditioning unit 100 to work synchronously, so that the driver and passengers are in a fresh and comfortable environment, improving the driving and riding comfort of the vehicle, preventing window fogging, improving the defrosting efficiency of the vehicle, and increasing the reuse rate of the air inside the vehicle by the automotive air conditioning unit 100, reducing the energy consumption of the automotive air conditioning unit 100, improving the thermal management efficiency of the automotive air conditioning unit 100, and making the automotive air conditioning unit 100 energy-saving and efficient.

[0047] In some embodiments, the air inlet box 111 has a first partition wall 1115, which is located inside the first air inlet cavity 1111. The first partition wall 1115 and the inner wall of the air inlet box 111 form an air guide channel 1116, and the second air inlet 1114 communicates with the second air inlet cavity 1112 through the air guide channel 1116.

[0048] The first partition wall 1115 can be integrally formed with the air inlet box 111, or it can be separately set from the air inlet box 111 and fixedly connected to it. For example, the first partition wall 1115 can be fixedly connected to the air inlet box 111 by welding, riveting or screwing, but it is not limited to this.

[0049] Understandably, since the second air inlet 1114 is located in the upper region of the air inlet box 111 and the second air inlet cavity 1112 is located in the lower region of the air inlet box 111, the two are not easily connected.

[0050] This application provides an airflow guide duct 1116 within the air intake box 111, connecting the second air inlet 1114 and the second air intake cavity 1112. This allows for rapid airflow between the second air inlet 1114 and the second air intake cavity 1112, ensuring the normal operation of the automotive air conditioning unit 100. Simultaneously, the airflow guide duct 1116 is located inside the air intake box 111, reducing the space occupied by the air intake box 111 and facilitating the overall design and assembly of the vehicle. Furthermore, it facilitates the overall machining and forming of the air intake box 111, improving its overall machining efficiency and reducing costs.

[0051] In some embodiments, refer to Figures 1 to 4 The first partition wall 1115 is provided with a first connecting port 1117 and a second connecting port 1118, both of which connect the air guide channel 1116 to the first air inlet cavity 1111.

[0052] Specifically, the housing 110 also includes a first air damper 113 and a second air damper 114. Both the first air damper 113 and the second air damper 114 are disposed in the first air inlet cavity 1111. The first air damper 113 is rotatably installed on the inner wall of the housing 110, and the first air damper 113 blocks the first air inlet 1113 or the first connecting port 1117. That is, the first air damper 113 is used to open or close the first air inlet 1113 and to open or close the first connecting port 1117. Specifically, the first damper 113 can block the first air inlet 1113 so that the first air inlet 1113 is not connected to the first air inlet cavity 1111 and the second air inlet cavity 1112. The air guide channel 1116 is connected to the first air inlet cavity 1111 through the first connecting port 1117, and the second air inlet 1114 is connected to the first air inlet cavity 1111. The first damper 113 can also block the first connecting port 1117 so that the first air inlet 1113 is connected to the first air inlet cavity 1111.

[0053] The second damper 114 is rotatably mounted on the first partition wall 1115. The second damper 114 blocks the second air inlet 1114 or the second connecting port 1118, that is, the second damper 114 is used to open or close the second air inlet 1114 and the second connecting port 1118. Specifically, the second damper 114 can block the second air inlet 1114 so that the second air inlet 1114 is not connected to the first air inlet cavity 1111 and the second air inlet cavity 1112. The air guide channel 1116 is connected to the first air inlet cavity 1111 through the second connecting port 1118, and the first air inlet 1113 is connected to the second air inlet cavity 1112. The second damper 114 can also block the second connecting port 1118 so that the second air inlet 1114 is connected to the second air inlet cavity 1112.

[0054] Understandably, this application blocks the first air inlet 1113 or the first connecting port 1117 by setting the first damper 113, and blocks the second air inlet 1114 or the second connecting port 1118 by setting the second damper 114, so as to realize the rapid switching of different working modes of the car air conditioning unit 100, facilitate the overall control of the car air conditioning unit 100, and improve the switching efficiency of different working modes of the car air conditioning unit 100.

[0055] In some embodiments, the automotive air conditioning unit 100 further includes: a first driver (not shown) and a second driver (not shown). The first driver is installed in the air intake box 111, and the power output end of the first driver is connected to the first air damper 113. The first driver is used to control the movement of the first air damper 113, thereby controlling the first air damper 113 to open the first air inlet 1113 and close the first connecting port 1117, or to close the first air inlet 1113 and open the first connecting port 1117.

[0056] The second driver is installed in the air inlet box 111, and the power output end of the second driver is connected to the second damper 114. The second driver is used to control the movement of the second damper 114, thereby controlling the second damper 114 to open the second air inlet 1114 and close the second connecting port 1118, or to close the second air inlet 1114 and open the second connecting port 1118.

[0057] The first driver and the second driver can be any one of a drive motor, an electromagnet, or a drive cylinder, but are not limited to these.

[0058] In some embodiments, refer to Figure 1The air intake actuator 120 includes an actuator body 121, a first drive impeller 122, and a second drive impeller 123. The actuator body 121 is disposed within a second air intake chamber 1112. The first drive impeller 122 is disposed within the first air intake chamber 1111 and is drive-connected to the power output end of the actuator body 121 to control the movement of the first drive impeller 122, thereby controlling the first drive impeller 122 to transport air located in the first air intake chamber 1111 to the first air distribution chamber 1123. The second drive impeller 123 is disposed within the second air intake chamber 1112 and is drive-connected to the power output end of the actuator body 121 to control the movement of the second drive impeller 123, thereby controlling the second drive impeller 123 to transport air from the second air intake chamber 1112 to the second air distribution chamber 1124.

[0059] In some embodiments, refer to Figure 1 The air inlet box 111 and the air distribution box 112 are separately provided, and the air inlet box 111 and the air distribution box 112 are fixedly connected. For example, the air inlet box 111 and the air distribution box 112 are fixed together by bolts, but are not limited thereto.

[0060] This application separates the air intake box 111 and the air distribution box 112, which facilitates the installation and arrangement of the air intake box 111 in the automobile, reduces the space occupied, increases the space of the passenger compartment, and improves the comfort of the passengers; at the same time, it facilitates the processing and forming of the air intake box 111 and the air distribution box 112, which facilitates the overall assembly of the automobile air conditioning device 100 and improves the assembly efficiency of the automobile air conditioning device 100.

[0061] In some embodiments, refer to Figure 1 The automotive air conditioning unit 100 also includes a filter element 130 and a fire-resistant element 140.

[0062] Specifically, some filter elements 130 are disposed in the first air inlet cavity 1111, and other filter elements 130 are disposed in the air guide channel 1116, so as to filter the air in the first air inlet cavity 1111 and the air guide channel 1116, ensuring the cleanliness of the air in the first air inlet cavity 1111 and the air guide channel 1116, and improving the driving comfort of the car occupants.

[0063] Fireproof element 140 is installed at the connection between air intake box 111 and air distribution box 112 to prevent the fire from spreading to the passenger compartment when the car catches fire, thereby improving the safety performance of the car air conditioning system 100.

[0064] Among them, the filter element 130 is an air filter, but is not limited to this.

[0065] In some embodiments, refer to Figure 1The air distribution box 112 includes a main body 1121 and a second partition wall 1122. The second partition wall 1122 is connected to the main body 1121 to divide the internal space of the main body 1121 into a first air distribution chamber 1123 and a second air distribution chamber 1124.

[0066] The second partition wall 1122 can be integrally formed with the main body 1121, or it can be separately set from the main body 1121 and fixedly connected to it. For example, the second partition wall 1122 can be fixedly connected to the main body 1121 by welding, riveting or screwing, but it is not limited to this.

[0067] Specifically, the main body 1121 is provided with a first air outlet 1125, a second air outlet 1126 and a third air outlet 1127. The first air outlet 1125 and the second air outlet 1126 are both connected to the first air distribution cavity 1123, and the third air outlet 1127 is connected to the second air distribution cavity 1124.

[0068] Specifically, the first air outlet 1125 is used to supply air to the windshield, rearview mirror and other parts of the car for defrosting; the second air outlet 1126 is used to supply air to each seat in the passenger compartment of the car; and the third air outlet 1127 is used to supply air to the bottom space in the passenger compartment of the car, so as to realize the air distribution box 112 to distribute air to different positions in the passenger compartment.

The third damper 181 is used to connect or block the first air distribution cavity 1123 and the heat management channel 1129 to heat the air in the first air distribution cavity 1123 according to actual needs, thereby reducing the energy consumption of the automotive air conditioning unit 100, achieving the energy-saving and emission-reduction effect of the automotive air conditioning unit 100, and making the automotive air conditioning unit 100 more energy-efficient.

[0084] The fourth damper 182 is disposed in the second air distribution cavity 1124 and is movably installed on the side of the thermal management section 1128 near the evaporator 150. The fourth damper 182 is used to connect or block the second air distribution cavity 1124 and the thermal management flow channel 1129 to heat the air in the second air distribution cavity 1124 according to actual needs, thereby reducing the energy consumption of the automotive air conditioning unit 100, achieving the energy-saving and emission-reduction effect of the automotive air conditioning unit 100, and making the automotive air conditioning unit 100 more energy-efficient.

[0085] In some embodiments, the automotive air conditioning unit 100 further includes a sixth drive (not shown) and a seventh drive (not shown).

[0086] The sixth actuator is installed on the main body 1121, and the power output end of the sixth actuator is connected to the third damper 181. The sixth actuator is used to control the movement of the third damper 181, thereby controlling the third damper 181 to connect or block the first air distribution chamber 1123 and the heat management channel 1129.

[0087] The seventh actuator is installed on the main body 1121, and the power output end of the seventh actuator is connected to the fourth damper 182.

[0088] The sixth and seventh actuators can be any one of a drive motor, an electromagnet, or a drive cylinder, but are not limited to these.

[0089] In some embodiments, the automotive air conditioning unit 100 further includes a controller (not shown), which is electrically or wirelessly connected to the air intake driver 120, the evaporator 150, the indoor condenser 160, the air heater 170, the first driver, the second driver, the third driver, the fourth driver, the fifth driver, the sixth driver, and the seventh driver, respectively, to achieve precise control of the air intake driver 120, the evaporator 150, the indoor condenser 160, the air heater 170, the first driver, the second driver, the third driver, the fourth driver, the fifth driver, the sixth driver, and the seventh driver, thereby achieving precise control and switching of different operating modes of the automotive air conditioning unit 100.

[0090] The controller can be any conventional product, conventional control chip, or other conventional product that can realize the control function in this application. No specific restrictions are imposed in this application.

[0091] In summary, the automotive air conditioning unit 100 of this application has an external circulation mode, an internal circulation mode, and an intermediate mode, and can be freely switched between the three modes.

[0092] Reference Figure 2When the car air conditioning unit 100 is in external circulation mode, the first air damper 113 is rotated to the first connecting port 1117 to block the first connecting port 1117, and the second air damper 114 is rotated to the second air inlet 1114 to block the second air inlet 1114. The first air inlet 1113 is connected to the first air inlet cavity 1111, and the first air inlet 1113 is connected to the second air inlet cavity 1112 through the second connecting port 1118 and the air guide channel 1116. When the air intake drive 120 operates, under the action of the first drive impeller 122, fresh external air flows from the first air intake 1113 to the first air intake chamber 1111, and then from the first air intake chamber 1111 to the first air distribution chamber 1123. The fresh air in the first air distribution chamber 1123 is delivered to the passenger compartment of the vehicle through the first air outlet 1125 and the second air outlet 1126. Simultaneously, under the action of the second drive impeller 123, fresh external air flows from the first air intake 1113 to the second air intake chamber 1112, and then from the second air intake chamber 1112 to the second air distribution chamber 1124. The fresh air in the second air distribution chamber 1124 is delivered to the passenger compartment of the vehicle through the third air outlet 1127. Because it is fresh air, this operating mode not only provides a fresh and comfortable environment for the driver and passengers, but also prevents the windows from fogging up and improves the vehicle's defrosting efficiency.

[0093] Reference Figure 3When the car air conditioning unit 100 is in the internal circulation mode, the first air damper 113 is rotated to the first air inlet 1113 to block the first air inlet 1113, and the second air damper 114 is rotated to the second connecting port 1118 to block the second connecting port 1118. The second air inlet 1114 is connected to the second air inlet cavity 1112, and the second air inlet 1114 is connected to the first air inlet cavity 1111 through the first connecting port 1117 and the air guide channel 1116. When the air intake driver 120 operates, under the action of the first drive impeller 122, the air in the passenger compartment of the car flows from the second air inlet 1114, the air guide duct 1116 and the first connecting port 1117 to the first air intake chamber 1111, and then from the first air intake chamber 1111 to the first air distribution chamber 1123. The air in the first air distribution chamber 1123 is delivered to the passenger compartment of the car through the first air outlet 1125 and the second air outlet 1126. At the same time, under the action of the second drive impeller 123, the air in the passenger compartment of the car flows from the second air inlet 1114 to the air guide duct 1116, then to the second air intake chamber 1112, and then from the second air intake chamber 1112 to the second air distribution chamber 1124. The air in the second air distribution chamber 1124 is delivered to the passenger compartment of the car through the third air outlet 1127. Since the air inside the car's passenger compartment remains almost constant, the original temperature inside the passenger compartment is maintained, reducing energy loss during air thermal management, improving the thermal management efficiency of the car's air conditioning unit 100, making the car's air conditioning unit 100 energy-saving and efficient, and at the same time improving the driving and riding comfort of the car's passengers.

[0094] Reference Figure 4When the car air conditioning unit 100 is in the intermediate working mode, the first air damper 113 is rotated to the first connecting port 1117 to block the first connecting port 1117, and the first air inlet 1113 is connected to the first air inlet cavity 1111; the second air damper 114 is rotated to the second connecting port 1118 to block the second connecting port 1118, and the second air inlet 1114 is connected to the second air inlet cavity 1112, and the first air inlet cavity 1111 and the second air inlet cavity 1112 are not connected. When the air intake driver 120 operates, under the action of the first drive impeller 122, fresh air from the outside flows from the first air inlet 1113 to the first air intake chamber 1111, and then from the first air intake chamber 1111 to the first air distribution chamber 1123. The fresh air in the first air distribution chamber 1123 is delivered to the passenger compartment of the car through the first air outlet 1125 and the second air outlet 1126. At the same time, under the action of the second drive impeller 123, the air in the passenger compartment of the car flows from the second air inlet 1114 to the air guide channel 1116, then to the second air intake chamber 1112, and then from the second air intake chamber 1112 to the second air distribution chamber 1124. The air in the second air distribution chamber 1124 is delivered to the passenger compartment of the car through the third air outlet 1127. This allows drivers and passengers to enjoy a fresh and comfortable environment, prevents windows from fogging up, and improves the car's defrosting efficiency. At the same time, it reduces energy loss during air thermal management, improves the thermal management efficiency of the car's air conditioning system 100, and makes the car's air conditioning system 100 more energy-efficient, while also improving the driving and riding comfort of the car's passengers.
