[0037] A vehicle's air conditioning system cools, heats, ventilates, and purifies the air in the cab, providing a comfortable driving environment for drivers and passengers. To improve the cooling and heating performance of the air conditioning system, a blower, cooling core, and heating core are typically installed within the air conditioning cabinet. This results in the cabinet occupying a large amount of space, especially on medium- and heavy-duty trucks. This reduces the interior space, and the cabinet's placement within the cab makes the system difficult to disassemble and maintain.

[0038] In this regard, this embodiment provides an air-conditioning box to solve the problem in the prior art that the air-conditioning box occupies a large space in the cab and the air-conditioning system is difficult to disassemble and maintain, and can be used in the field of vehicle technology.

[0039] Reference Figures 1-6The air-conditioning box includes a main box 1, a blower 2 and a temperature adjustment component 3. The main box 1 is arranged outside the cab. The main box 1 has an air flow channel 11 and an external circulation air inlet 12, an internal circulation air inlet 13 and an air outlet 14 connected to the air flow channel 11. The external circulation air inlet 12 is used to connect the air outside the cab, and the internal circulation air inlet 13 is used to connect the air inside the cab. The blower 2 is arranged in the air flow channel 11 and is used to blow the gas from the external circulation air inlet 12 to the air outlet 14, or to blow the gas from the internal circulation air inlet 13 to the air outlet 14. The temperature adjustment component 3 is arranged in the air flow channel 11 and is used to change the temperature of the gas so that the gas can enter the air flow channel 11 from the external circulation air inlet 12 or the internal circulation air inlet 13, change the temperature of the gas through the temperature adjustment component 3, and flow to the air outlet 14 under the action of the blower 2, so that the cold air or hot air is discharged from the air outlet 14. In addition, in the air-conditioning box, the main box 1 is arranged outside the cab, which can save the internal space of the cab, and the main box 1 is easy to disassemble and assemble, so as to facilitate the operator to maintain the blower 2 and temperature adjustment component 3 inside the main box 1.

[0040] Continue to refer to Figures 1-6 The main box 1 includes a first box 15 and a second box 16. The first box 15 and the second box 16 are separated by a partition plate 17 with a through hole 171. The external circulation air inlet 12 and the internal circulation air inlet 13 are opened in the first box 15, and the air outlet 14 is opened in the second box 16. The blower 2 and the temperature adjustment component 3 are both arranged in the second box 16. After the air enters the interior of the first box 15 through the external circulation air inlet 12 or the internal circulation air inlet 13 set in the first box 15, it enters the interior of the second box 16 through the through hole 171, and flows to the temperature adjustment component 3 under the action of the blower 2, and is finally discharged from the air outlet 14.

[0041] Continue to refer to Figures 1-6 The first housing 15 is further provided with an external circulation damper 121 and an internal circulation damper 131. The external circulation damper 121 is used to connect or disconnect the external circulation air inlet 12 with the through hole 171, thereby opening or closing the external circulation of the vehicle air conditioning system. The internal circulation damper 131 is used to connect or disconnect the internal circulation air inlet 13 with the through hole 171, thereby opening or closing the internal circulation of the vehicle air conditioning system.

[0042] Continue to refer to Figures 1-6 A rainwater guide surface 18 is provided at the upper end of the main box body 1. The rainwater guide surface 18 is set at an angle, so that the rainwater accumulated outside the main box body 1 can be discharged through the rainwater guide surface 18 to avoid rainwater leakage. At the same time, it can also play a certain dust-proof effect and increase the aesthetics of the air-conditioning box body.

[0043] Optionally, the rainwater guide surface 18 includes a first guide surface 181 and a second guide surface 182, the first guide surface 181 is connected to the second guide surface 182, and the first guide surface 181 is located above the second guide surface 182, and the angle between the first guide surface 181 and the vertical direction is greater than the angle between the second guide surface 182 and the vertical direction, so that the extension direction of the second guide surface 182 is closer to the vertical direction, and after the rainwater flows from the first guide surface 181 to the second guide surface 182, it can be quickly discharged through the second guide surface 182.

[0044] Continue to refer to Figures 1-6 The temperature regulating assembly 3 includes a cold air core 31 and a warm air core 32, and the temperature regulating assembly 3 has a cold air mode and a warm air mode. When the temperature regulating assembly 3 is in the cold air mode, the temperature regulating assembly 3 is configured to allow the gas to only pass through the cold air core 31, which can reduce the temperature of the gas and achieve a dehumidification effect, thereby blowing dry cold air into the cab. At this time, the direction of the airflow is as follows: Figure 2 As shown by the arrow in , when the temperature adjustment component 3 is in the warm air mode, the temperature adjustment component 3 is configured to allow the gas to pass through the cold air core 31 and the warm air core 32 in sequence. At this time, the cold air core 31 can be used for dehumidification, and the warm air core 32 can be used to increase the temperature of the gas, thereby blowing dry warm air into the cab. At this time, the direction of the airflow is as follows: Figure 3 As shown by the arrow in .

[0045] Continue to refer to Figures 1-6 The temperature regulating component 3 also includes a mode damper 33, which has an open state and a closed state. When the mode damper 33 is in the open state, the gas can flow through the cold air core 31, the mode damper 33 and the warm air core 32 in sequence, so that the temperature regulating component 3 is in the warm air mode. When the mode damper 33 is in the closed state, the gas can only pass through the cold air core 31, so that the temperature regulating component 3 is in the cold air mode, thereby adjusting the working mode of the temperature regulating component 3 by changing the state of the mode damper 33.

[0046] Specifically, along the flow direction of the gas, the cold air core 31, the mode damper 33 and the warm air core 32 are arranged in sequence. The mode damper 33 includes a fixed plate 331 fixedly arranged on the main box body 1 and two fan blades 332 rotatably arranged on the main box body 1. The two fan blades 332 are respectively located at the upper and lower ends of the fixed plate 331 and can be rotated relative to the main box body 1 so that the outer wall of the fan blade 332 is against the fixed plate 331 or separated from the fixed plate 331.

[0047] When the fan blade 332 is against the fixed plate 331, the gas can only bypass from one side of the mode damper 33 and will not pass through the warm air core 32. At this time, the temperature adjustment component 3 is in the cold air mode; when the fan blade 332 is separated from the fixed plate 331, the gas can pass through the gap between the fan blade 332 and the fixed plate 331 and further flow to the warm air core 32. At this time, the temperature adjustment component 3 is in the warm air mode.

[0048] Continue to refer to Figures 1-6 The air conditioning box body also includes an air distribution box body 4, the inner cavity of the air distribution box body 4 is connected to the air outlet 14, the inner cavity of the air distribution box body 4 is connected to the face blowing air duct, the foot blowing air duct and the defogger air duct, the face blowing air duct is used to guide the air to the driver's face, the foot blowing air duct is used to guide the air to the driver's feet, and the defogger air duct is used to guide the air to the inside of the front windshield. The inner cavity of the air distribution box body 4 is provided with an air distribution damper 41, which is used to connect the air outlet 14 with the face blowing air duct, or Alternatively, the air outlet 14 can be connected to the foot-blowing duct, or alternatively, the air outlet 14 can be connected to the defogger duct, allowing air to enter all three ducts. When the air outlet 14 is connected to the face-blowing duct, air can pass through the face-blowing duct and be blown toward the driver's face. When the air outlet 14 is connected to the foot-blowing duct, air can pass through the foot-blowing duct and be blown toward the driver's feet. When the air outlet 14 is connected to the defogger duct, air can pass through the defogger duct and be blown toward the inside of the front windshield. The air distribution damper 41 includes multiple fan blades, and the direction of air guidance can be changed by changing the angle of each fan blade. Its specific structure is a relatively mature solution in the field and will not be described in detail.

[0049] Optionally, the air distribution box 4 is arranged in the cab to avoid too many structures being arranged outside the cab, and since the face air duct, foot air duct and defogger air duct need to be arranged inside the vehicle body, such an arrangement makes the air distribution damper 41 closer to the above structure, which is convenient for the layout of the overall structure of the vehicle air-conditioning system.

[0050] This embodiment also provides a vehicle air-conditioning system, including the above-mentioned air-conditioning box, and also including an internal circulation air duct arranged in the cab, the internal circulation air duct is used for the air inside the cab to enter, and the internal circulation air duct is connected to the internal circulation air inlet 13. Gas can enter the air flow channel 11 from the external circulation air inlet 12 or the internal circulation air inlet 13, change the temperature of the gas through the temperature adjustment component 3, and flow to the air outlet 14 under the action of the blower 2, so that cold air or hot air is discharged from the air outlet 14. In addition, in the air-conditioning box, the main box 1 is arranged outside the cab, which can save the internal space of the cab, and the main box 1 is easy to disassemble and assemble, so that the operator can easily maintain the blower 2 and temperature adjustment component 3 inside the main box 1.

[0051] Optionally, the vehicle air-conditioning system also includes a face-blowing air duct, a foot-blowing air duct and a defogger air duct arranged inside the vehicle body. The face-blowing air duct is used to guide the air to the driver's face, the foot-blowing air duct is used to guide the air to the driver's feet, and the defogger air duct is used to guide the air to the inside of the front windshield.

[0052] This embodiment also provides a vehicle, including the above-mentioned vehicle air-conditioning system and a cab. The main box body 1 is arranged outside the cab, which can save the internal space of the cab and facilitate the disassembly and maintenance of the vehicle air-conditioning system.

[0053] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
