[0045] As mentioned above, the general concept of this utility model embodiment is to provide an air conditioning unit structure 10. Through optimized design, the air conditioning unit structure 10 mainly consists of an air intake module 100, an evaporator module 200, a blower module 300, and a dual-temperature zone air distribution module 400. The air intake module 100 can switch between internal and external air circulation modes, introducing air into the evaporator module 200. After being cooled by the evaporator module 200, the air enters the blower module 300, which generates airflow, allowing air outside the air intake module 100 to enter the air conditioning unit structure 10. The air is then sequentially introduced into the dual-temperature zone air distribution module 400 through the air intake module 100, evaporator module 200, and blower module 300. The dual-temperature zone air distribution module 400 has two independent temperature zones, which can regulate the temperature of the air flowing through them. It can also switch the mode damper state to mix the air discharged from each temperature zone and deliver it into the cabin 30 in different air outlet modes. This achieves dual-temperature zone temperature regulation of the air conditioning unit structure 10 and switching between different air outlet modes, thereby improving the functional versatility of the air conditioning unit structure 10, improving the mixing effect of cold and warm air, and enhancing the passenger experience in the cabin 30.

[0046] Furthermore, by arranging the aforementioned air conditioning unit structure 10 within the front engine compartment 20 of the vehicle 1, dashboard space can be effectively saved, maintenance and disassembly convenience can be improved, and noise within the passenger compartment 30 of the vehicle 1 can be reduced, thereby effectively improving the NVH performance of the vehicle 1.

[0047] Based on the above concept, and referring to Figures 1-10 This utility model provides an air conditioning unit structure 10 for placement in the front engine compartment 20 of a vehicle 1. The air conditioning unit structure 10 includes: an air intake module 100 for switching between internal and external air circulation and introducing air into the air conditioning unit structure 10; an evaporator module 200 connected to the air intake module 100 for receiving and cooling the air discharged from the air intake module 100; a blower module 300 connected to the end of the evaporator module 200 away from the air intake module 100 for receiving the cooled air discharged from the evaporator module 200 and forming an airflow; and a dual-temperature zone air distribution module 4. 00, arranged on one side of the air inlet module 100 and evaporator module 200, and connected to the blower module 300, is used to receive the air introduced by the blower module 300; the dual-temperature zone air distribution module 400 is provided with two independent temperature zones, and the end of the two temperature zones away from the blower module 300 is provided with a mode damper; wherein, the dual-temperature zone air distribution module 400 is configured to independently adjust the temperature of the air flowing through each temperature zone, and to switch the mode damper state to mix and deliver the air discharged from each temperature zone to the interior of the cabin 30 in different air outlet modes.

[0048] It is understood that the front bulkhead of the vehicle 1 separates the passenger compartment 30 and the front engine compartment 20 in the front-rear direction. In this embodiment, the air conditioning unit structure 10 is arranged inside the front engine compartment 20. One end of the air intake module 100 of the air conditioning unit structure 10 is connected to the front bulkhead of the vehicle 1, and the other end is connected to the evaporator module 200. The end of the evaporator module 200 away from the air intake module 100 is connected to the blower module 300. The dual-temperature zone air intake module 400 is arranged on one side of the air intake module 100 and the evaporator module 200 and is connected to the blower module 300. Therefore, different air intakes (such as internal circulation air intake) can be designed on the air intake module 100. The system includes an air intake and an external air intake, which enables switching between internal and external air intake modes. Air from outside the intake module 100 is cooled by the airflow generated by the blower module 300. Then, it is introduced into the dual-temperature zone air distribution module 400 through the blower module 300. After the temperature of the two temperature zones in the dual-temperature zone air distribution module 400 is adjusted, the air is mixed and delivered to the interior of the passenger cabin 30 by the mode damper in the corresponding air outlet mode. By switching the mode damper state, various air outlet modes such as face blowing mode, foot blowing mode, or defrosting mode can be switched to meet the diverse needs during the ride.

[0049] The following embodiments provide a detailed description of each component of the air conditioning unit structure 10.

[0050] refer to Figure 2 , Figure 6 , Figure 8 and Figure 9As shown, in some embodiments, the dual-temperature zone ventilation module 400 includes a left air distribution box housing 401, a first mode damper 402, a temperature zone partition 403, a second mode damper 404, a right air distribution box housing 406, an internal cooling condenser 422, a warm air core 423, and a mode control component; the left air distribution box housing 401 and the right air distribution box housing 406 are connected and together form a ventilation space; the temperature zone partition 403 is arranged between the left air distribution box housing 401 and the right air distribution box housing 406, and is connected to the left air distribution box housing 401 and the right air distribution box housing 406 respectively, so as to divide the ventilation space into two independent temperature zones. Under the isolation of the temperature zone partition 403, each temperature zone has an independent air inlet; the internal cooling condenser 422 and the warm air core 423 are both inclinedly arranged in the two temperature zones through the temperature zone partition 403; the left air distribution box housing 401 and the right air distribution box housing 406 are connected and together form a ventilation space ... One end of the right housing 406 of the air box is connected to the blower module 300, and the other end together forms a plurality of mode air outlets arranged at intervals along the height direction; the first mode damper 402 and the second mode damper 404 are arranged at intervals along the height direction adjacent to the mode air outlets, and are rotatably connected between the left air distribution box housing 401 and the right air distribution box housing 406; the mode control component is connected to one side of the right air distribution box housing 406, located between the air inlet module 100 and the right air distribution box housing 406, and is respectively connected to the first mode damper 402 and the second mode damper 404; wherein, the first mode damper 402 and the second mode damper 404 are respectively configured to be able to rotate to different positions under the drive of the mode control component to adjust the opening of the corresponding mode air outlet, so as to mix and deliver the exhaust air of each temperature zone to the interior of the cabin 30 in different air outlet modes.

[0051] In this embodiment, the left air distribution box housing 401 and the right air distribution box housing 406 are connected in the left-right direction and together form a ventilation space. After the left air distribution box housing 401 and the right air distribution box housing 406 are connected, one end of the left air distribution box housing 401 and the right air distribution box housing 406 are connected to the blower module 300, and the other end together forms a plurality of pattern air outlets (unlabeled) arranged at intervals along the height direction. The temperature zone partition 403 is arranged vertically and connected to the left air distribution box housing 401 and the right air distribution box housing 406. Between 6, the ventilation space is vertically divided into two independent temperature zones. Two oblique through holes are opened at intervals on the temperature zone partition 403. The internal cooling condenser 422 and the heating core 423 pass through the corresponding through holes on the temperature zone partition 403 and are set up vertically and vertically in the two temperature zones. Thus, air can be introduced into the two temperature zones through the blower module 300. In each temperature zone, after being cooled by the internal cooling condenser 422 and / or heated by the heating core 423, it is discharged from the corresponding mode air outlet.

[0052] It should be understood that the internal cooling condenser 422 and the heating core 423 are tilted vertically so that the air introduced by the blower module 300 can fully contact the internal cooling condenser 422 or the heating core 423, thereby improving the heat exchange efficiency of the air.

[0053] Furthermore, the first mode damper 402 and the second mode damper 404 are arranged at intervals along the height direction adjacent to the mode air outlet. The first mode damper 402 is located at the bottom of the second mode damper 404. Both the first mode damper 402 and the second mode damper 404 are rotatably connected between the left air distribution box housing 401 and the right air distribution box housing 406, and are both connected to a mode control component arranged on the outside of the right air distribution box housing 406. The mode control component is located between the air inlet module 100 and the right air distribution box housing 406. The first mode damper 402 and the second mode damper 404 are respectively configured to be able to... Driven by the mode control component, the air outlets are rotated to different positions to adjust the opening of the corresponding mode air outlets. The air discharged from each temperature zone is mixed and delivered to the cabin 30 in different air outlet modes. That is, under the drive of the mode control component, the first mode damper 402 can block or not block the mode air outlet located at the lower position, and the second mode damper 404 can block or not block the mode air outlet located at the higher position. By controlling the opening of the corresponding mode air outlets through the first mode damper 402 and the second mode damper 404, a combination of air outlets of different modes can be realized, thereby realizing the switching of multiple different air outlet modes.

The second temperature regulating damper 420 is disposed inside the left air distribution box housing 401, with its two ends along the height direction spaced apart from the left air distribution box housing 401, and its two ends along the width direction slidably connected to the temperature zone partition 403 and the left air distribution box housing 401 respectively via slide rails 424; the first temperature regulating damper 419 and the second temperature regulating damper 420 are respectively connected to the mode control component, and the first temperature regulating damper 419 and the second temperature regulating damper 420 are respectively configured to slide to different positions under the drive of the mode control component to adjust the air flow through the internal cooling condenser 422 and the warm air core 423.

[0055] It is understood that the slide rails 424 are respectively set on both sides of the temperature zone partition 403, on the opposite side of the right air distribution box housing 406 and the left air distribution box housing 401. The first temperature regulating damper 419 and the second temperature regulating damper 420 are both arc-shaped plate-shaped parts, set at the air inlet of the corresponding temperature zone (i.e., the end away from the mode air outlet), and the inner curved surface faces the inner cooling condenser 422 and the warm air core 423; wherein, the two sides of the first temperature regulating damper 419 are respectively slidably connected to the two slide rails 424 on the temperature zone partition 403 and the right air distribution box housing 406, and the two sides of the second temperature regulating damper 420 are respectively slidably connected to the two slide rails 424 on the temperature zone partition 403 and the left air distribution box housing 401. The first temperature regulating damper 419 is slidably connected to the two slide rails 424 on the temperature zone partition 403 and the left air distribution box housing 401. Both ends of the first temperature regulating damper 419 and the second temperature regulating damper 420 are spaced apart from the right housing 406 of the air distribution box in the vertical direction, and both ends of the second temperature regulating damper 420 are spaced apart from the left housing 401 of the air distribution box in the vertical direction to allow air circulation. The first temperature regulating damper 419 and the second temperature regulating damper 420 are respectively connected to the mode control component. Under the drive of the mode control component, the first temperature regulating damper 419 or the second temperature regulating damper 420 can move in the vertical direction, so that the interval between the upper and lower intervals of the first temperature regulating damper 419 or the second temperature regulating damper 420 increases or decreases, thereby changing the air flow through the internal cooling condenser 422 and the warm air core 423, thereby realizing independent adjustment of the air temperature flowing through each temperature zone.

[0056] It should be noted that the reference Figure 8 As shown, the cooling air discharged from the blower module 300 enters the corresponding temperature zone through the top interval area of ​​the first temperature regulating damper 419 or the second temperature regulating damper 420. It is less affected by the internal cooling condenser 422 and the warm air core 423. However, the cooling air discharged from the blower module 300 enters the corresponding temperature zone through the bottom interval area of ​​the first temperature regulating damper 419 or the second temperature regulating damper 420. It needs to flow through the internal cooling condenser 422 and the warm air core 423 in sequence before mixing with the cooling air entering from the top interval area and then being discharged. This significantly improves the mixing effect of cold and warm air. Furthermore, by adjusting the spacing of the top or bottom interval areas of each corresponding temperature zone through the first temperature regulating damper 419 or the second temperature regulating damper 420, the airflow through the internal cooling condenser 422 and the warm air core 423 can be well controlled, achieving independent control of the air temperature in each temperature zone.

[0057] Continue to refer to Figure 6 and Figure 9To drive the first temperature regulating damper 419, the second temperature regulating damper 420, the first mode damper 402, and the second mode damper 404, in some embodiments, the mode control assembly includes: a first mode link 407, a second mode link 408, a third mode link 409, a mode disk 410, a mode motor 411, a first connector 412, a first stepper motor 413, a second stepper motor 414, a first transmission gear 415, a second connector 416, a second transmission gear 417, and a first damper drive shaft 418.

Gear 415 is rotatably connected to the first damper drive shaft 418, and the first damper drive shaft 418 is connected to the first temperature regulating damper 419. The first temperature regulating damper 419 can slide to the target position under the drive of the first damper drive shaft 418. The output shaft of the second stepper motor 414 is rotatably connected to the second damper drive shaft 421 through the second transmission gear 417. The second damper drive shaft 421 is connected to the second temperature regulating damper 420. The second temperature regulating damper 420 can slide to the target position under the drive of the second damper drive shaft 421.

[0058] In this embodiment, the first connector 412 can be a bolt. The mode motor 411 is fixedly connected to the right housing 406 of the air distribution box through the first connector 412. The mode disk 410 is fixed between the right housing 406 of the air distribution box and the mode motor 411. One end of the third mode link 409 is connected to the mode disk 410, and the other end is connected to the mode motor 411, so that the mode motor 411 can drive the mode disk 410 to rotate through the third mode link 409. The mode disk 410 is also connected to the first mode link 407 and the second mode link 408. The end of the first mode link 407 away from the mode disk 410 is connected to the second mode damper 404, and the end of the second mode link 408 away from the mode disk 410 is connected to the first mode damper 402. Under the drive of the mode motor 411, the mode disk 410 can drive the second mode damper 404 or the first mode damper 402 to rotate to the target position to block or open the corresponding mode damper, thereby realizing the switching of different air outlet modes.

[0059] Furthermore, the first stepper motor 413 and the second stepper motor 414 are fixedly connected to the outside of the right housing 406 of the air distribution box along a vertical interval. The first transmission gear 415 and the second transmission gear 417 are connected to the outside of the right housing 406 of the air distribution box through the second connector 416 (such as a screw). The output shaft of the first stepper motor 413 is rotatably connected to the first damper transmission shaft 418 through the first transmission gear 415. The first damper transmission shaft 418 is arranged inside the right housing 406 of the air distribution box and is keyed to the first temperature regulating damper 419. The first temperature regulating damper 419 can slide to the target position under the drive of the first damper drive shaft 418; the output shaft of the second stepper motor 414 is rotatably connected to the second damper drive shaft 421 through the second transmission gear 417. The second damper drive shaft 421 passes between the left air distribution box housing 401 and the right air distribution box housing 406. The second damper drive shaft 421 is keyed to the second temperature regulating damper 420. The second temperature regulating damper 420 can slide to the target position under the drive of the second damper drive shaft 421. When it is necessary to adjust the air temperature of a certain temperature zone, for example, if it is necessary to increase the air temperature in the temperature zone inside the right housing 406 of the air distribution box, the first stepper motor 413 drives the first transmission gear 415 to rotate, which in turn drives the first damper drive shaft 418 to rotate. As the first damper drive shaft 418 rotates, the first temperature regulating damper 419 will move smoothly along the slide rail 424 to a new position that can reduce the entry of cold air or increase the retention of hot air, thereby realizing the adjustment of the air temperature in the temperature zone inside the right housing 406 of the air distribution box.

[0060] In some embodiments, the dual-temperature air distribution module 400 further includes a first sealing element 405; multiple mode air outlets include a first air outlet, a second air outlet, and a third air outlet arranged sequentially at intervals along the height direction; one end of the first sealing element 405 is connected to the first air outlet, the second air outlet, and the third air outlet respectively, and the other end is used to connect to the air duct of the cabin 30; the first air outlet and the second air outlet can be at least partially blocked by the second mode damper 404, and the second air outlet and the third air outlet can be at least partially blocked by the first mode damper 402; the first air outlet, the second air outlet, and the third air outlet are respectively connected to air ducts at different heights within the cabin 30.

[0061] It should be noted that the reference Figure 6 As shown, the first, second, and third air outlets are not marked. The first air outlet is located at the top, the second air outlet is located in the middle, and the third air outlet is located at the bottom. The opening of the first air outlet is mainly controlled by the second mode damper 404, the opening of the third air outlet is mainly controlled by the first mode damper 402, and the opening of the second air outlet can be controlled by both the second mode damper 404 and the first mode damper 402. The first, second, and third air outlets are connected to air ducts at different heights within the passenger compartment 30 (for example, the first air outlet can connect to the air duct blowing towards the face at a higher position, the second air outlet can connect to the air duct for defrosting at a middle position, and the third air outlet can connect to the air duct blowing towards the feet at a lower position). The first sealing element 405 is a sealing sponge that is adapted to the contour shape of the first, second, and third air outlets to facilitate the sealing of the dual-temperature air duct module 400 with the external air duct when the dual-temperature air duct module 400 is connected to the automotive air duct.

[0062] Based on this, the second mode damper 404 and the first mode damper 402 can be rotated to the upper limit position, the middle position and the lower limit position respectively under the drive of the mode motor 411, the mode disk 410 and other connecting rods, so as to block the first air outlet, the second air outlet or the third air outlet respectively, thereby realizing the switching of different air outlet modes.

[0063] In some specific embodiments, the air outlet modes include a face blowing mode, a foot blowing mode, a defrost mode, a defrost and foot blowing mode, or a face and foot blowing mode; when the air outlet mode is face blowing mode, the mode motor 411 drives the mode disk 410 to rotate, and drives the second mode damper 404 to rotate to the upper limit position and the first mode damper 402 to rotate to the lower limit position through the corresponding mode linkage; when the air outlet mode is foot blowing mode, the mode motor 411 drives the mode disk 410 to rotate, and drives the second mode damper 404 to rotate to the upper limit position and the first mode damper 402 to rotate to the upper limit position through the corresponding linkage; when the air outlet mode is defrost mode, the mode motor... 411 drives the mode disk 410 to rotate, and drives the second mode damper 404 to rotate to the lower limit position and the first mode damper 402 to rotate to the lower limit position through the corresponding linkage. When the air outlet mode is defrosting and foot blowing mode, the mode motor 411 drives the mode disk 410 to rotate, and drives the second mode damper 404 to rotate to the lower limit position and the first mode damper 402 to rotate to the middle position through the corresponding linkage. When the air outlet mode is blowing face and feet mode, the mode motor 411 drives the mode disk 410 to rotate, and drives the second mode damper 404 to rotate to the upper limit position and the first mode damper 402 to rotate to the middle position through the corresponding linkage.

[0064] Therefore, the air conditioning unit structure 10 provided in this embodiment of the present invention, through the design of the dual-temperature zone air distribution module 400, can not only achieve independent temperature adjustment of the dual temperature zones, but also achieve switching of at least 5 air outlet modes, so as to significantly improve the riding experience of passengers inside the cabin.

[0065] refer to Figure 2 , Figure 3 and Figure 7As shown, in some embodiments, the air intake module 100 includes an air intake housing 101, a second seal 102, an internal and external circulation damper 103, a third seal 104, a filter element 105, a filter element plug 106, a mode switching motor 107, a first connecting rod 108, a second connecting rod 109, and a third connecting member 110. One end of the air intake housing 101 is connected to the evaporator module 200 to discharge air into the evaporator module 200. The other end of the air intake housing 101, away from the evaporator module 200, forms an internal circulation air intake port (not marked) for air intake in the internal circulation air intake mode. The second seal 102 is a sealing sponge. One end of the second seal 102 is shaped to fit the contour of the internal circulation air intake port and is connected to the internal circulation air intake port. The other end is used to connect to the passenger cabin. 30 Internal circulation air duct; An external circulation air inlet (unmarked) is provided on the top of the air inlet housing 101 near the internal circulation air inlet (unmarked). The internal and external circulation dampers 103 are located at the external circulation air inlet and are rotatably connected to the air inlet housing 101. The internal and external circulation dampers 103 can close or open the external circulation air inlet to realize the switching of internal and external circulation air intake modes. For example, when the internal and external circulation dampers 103 open the external circulation air inlet, the air discharged from the external circulation air duct of the vehicle 1 can enter the air inlet housing 101 through the external circulation air inlet. This is the external circulation air intake mode. When the internal and external circulation dampers 103 close the external circulation air inlet, the air discharged from the internal circulation air duct of the vehicle 1 can enter the air inlet housing 101 through the internal circulation air inlet. This is the internal circulation air intake mode.

[0066] Furthermore, the third seal 104 is a sealing sponge. One end of the third seal 104 is shaped to match the air inlet profile at the internal and external circulation damper 103 and is connected to the external circulation air inlet at the internal and external circulation damper 103. The other end is used to connect to the external circulation air duct of the passenger compartment 30 to facilitate the sealing of the external circulation air duct and the air inlet housing 101. The filter element 105 is disposed inside the air inlet housing 101 and is away from the internal and external circulation damper 103 and the internal circulation air inlet. It is used to filter the air flowing through the air inlet module 100. The filter element plug 106 is disposed on the top of the filter element 105 and is detachably connected to the air inlet housing 101 to fix the filter element 105 inside the air inlet housing 101. Since the air conditioning box structure 10 is disposed inside the front engine compartment 20 of the vehicle 1, this design also makes it easier to replace the filter element 105 without disassembling other structural components.

[0067] To achieve the switching between internal and external circulation air intake modes, a mode switching motor 107 is installed between the air intake housing 101 and the right housing 406 of the air distribution box. The mode switching motor 107 is fixed to one side of the air intake housing 101 by a third connector 110 (such as a bolt). One end of the first connecting rod 108 is connected to the mode switching motor 107, and the other end is connected to the second connecting rod 109. The second connecting rod 109 is connected to the internal and external circulation damper 103, so that the internal and external circulation damper 103 can be rotated and adjusted to open or close the external circulation air intake under the drive of the mode switching motor 107, so as to control the opening degree of the external circulation air intake and thus achieve the switching of the external circulation air intake mode. For example, when the internal and external circulation damper 103 is rotated to the upper limit position, it is internal circulation air intake, and when the internal and external circulation damper 103 is rotated to the lower limit position, it is external circulation air intake.

One end of the blower inlet housing 301 is connected to the evaporator module 200, and the other end is connected to the blower housing 302, so that the air discharged from the evaporator module 200 can enter the blower housing 302 through the blower inlet housing 301. The blower motor 303 is fixedly mounted on the blower via the fifth connector 304 (such as a bolt). Inside the housing 302, the blower motor 303 serves as the power source for the blower module 300, generating airflow through blade rotation to achieve directional airflow. The air inlet of the blower outlet housing 305 is connected to the blower housing 302, and the air outlet of the blower outlet housing 305 is connected to the dual-temperature zone air distribution module 400. The speed control module 307 is fixed inside the air inlet of the blower outlet housing 305 via a sixth connector 306 (such as a bolt) to adjust the airflow at the air outlet of the blower outlet housing 305, thereby controlling the overall airflow of the air conditioning unit structure 10.

[0070] In some embodiments, to further improve the connection stability of the air intake module 100, evaporator module 200, blower module 300 and dual-temperature zone air distribution module 400 of the air conditioning unit structure 10, the air intake module 100 and the evaporator module 200 can be sealed by groove and boss features, and fixed by clip features and screws. The evaporator module 200 and the blower module 300 can also be sealed by groove and boss features, and fixed by clip features and screws. The blower module 300 and the dual-temperature zone air distribution module 400 can also be sealed by groove and boss features, and fixed by clip features and screws. The evaporator module 200 and the dual-temperature zone air distribution module 400 can be fixed by bolts using feature matching.

Figure 10 The mounting foot 500 shown has a mounting through hole for securing it to a car body sheet metal bracket or support using bolts and nuts.
