[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0020] The following is for reference. Figures 1-5 An air conditioning system 100 according to an embodiment of the present utility model is described.

[0021] like Figures 1-4 As shown, the air conditioning system 100 of the vehicle according to this utility model includes: an air conditioning host 1, which has a host air inlet 11; an air inlet box 2, which defines an air inlet channel 21 and forms an internal circulation inlet and an external circulation inlet 22, the inlet end of the air inlet channel 21 is connected to both the internal circulation inlet and the external circulation inlet 22, and the outlet end of the air inlet channel 21 is connected to the host air inlet 11; and a filter structure 3, which is disposed in the air inlet channel 21 and fixed to the air inlet box 2.

[0022] The air conditioning unit 1 has an air inlet 11 through which air enters. The air conditioning unit 1 also has an evaporator core 17 and a heater core 18. In some embodiments of this application, when the interior temperature is high and the air conditioning system 100 is cooling, the air entering the air conditioning unit 1 is cooled by the evaporator core 17. In some embodiments of this application, when the interior temperature is low and the air conditioning system 100 is heating, the air entering the air conditioning unit 1 is heated by the heater core 18. In some embodiments of this application, the air entering the air conditioning unit 1 can also be partially cooled by the evaporator core 17 and partially heated by the heater core 18, allowing for flexible temperature adjustment through the cooperation of the evaporator core 17 and the heater core 18.

[0023] The air inlet box 2 may be, but is not limited to, constructed as a blower. The air inlet box 2 defines an air inlet channel 21 and has an internal circulation inlet and an external circulation inlet 22. The inlet end of the air inlet channel 21 is connected to both the internal circulation inlet and the external circulation inlet 22. When the air conditioning system 100 is in internal circulation mode, air enters the air inlet channel 21 from the internal circulation inlet. When the air conditioning system 100 is in external circulation mode, air enters the air inlet channel 21 from the external circulation inlet 22. The outlet end of the air inlet channel 21 is connected to the main unit air inlet 11, so that air sequentially passes through the air inlet channel 21 and the main unit air inlet 11 into the air conditioning unit 1, facilitating appropriate cooling or heating of the air.

[0024] The filter structure 3 is located within the air inlet channel 21 and fixed to the air inlet box 2. For example, the filter structure 3 can be snapped onto the air inlet box 2, or it can be fixed to the air inlet box 2 with bolts. Both the internal and external circulating air can be filtered by the filter structure 3 when passing through the air inlet channel 21, thereby improving the air quality of the passenger compartment. Furthermore, the filtered internal and external circulating air enters the air conditioning unit 1, which can reduce the risk of blockage of components such as the evaporator core 17 and the heater core 18 inside the air conditioning unit 1, which is beneficial to maintaining the performance of the air conditioning system 100 and extending the service life of the air conditioning system 100.

[0025] Specifically, the air conditioning system 100 also includes an internal and external circulation damper 24. The internal and external circulation damper 24 has an internal and external circulation damper motor 23. When the air conditioning system 100 is in internal circulation mode, the air conditioning unit 1 is working. The internal and external circulation damper motor 23 drives the internal and external circulation damper 24 to close the external circulation inlet 22 and open the internal circulation inlet. It also drives the gas in the passenger compartment to enter the air intake channel 21 through the internal circulation inlet. After being filtered by the filter structure 3 in the air intake channel 21, the air enters the air conditioning unit 1 through the air intake port 11 of the unit. The air entering the air conditioning unit 1 is regulated to a suitable temperature by the evaporator core 17 and the heating core 18 and then enters the passenger compartment to make the temperature of the passenger compartment suitable.

[0026] When the air conditioning system 100 is in external circulation mode, the air conditioning unit 1 is working. The internal and external circulation damper motor 23 drives the internal and external circulation damper 24 to close the internal circulation inlet and open the external circulation inlet 22. It also drives the gas in the passenger compartment to enter the air intake channel 21 through the external circulation inlet 22. After being filtered by the filter structure 3 in the air intake channel 21, the air enters the air conditioning unit 1 through the air intake port 11 of the unit. The air entering the air conditioning unit 1 is regulated to a suitable temperature by the evaporator core 17 and the heating core 18 and then enters the passenger compartment to make the temperature in the passenger compartment suitable.

[0027] Therefore, by placing the filter structure 3 inside the air inlet channel 21 and fixing it to the air inlet box 2, both the internal and external circulating air can be filtered by the filter structure 3 when passing through the air inlet channel 21, thereby improving the air quality of the passenger compartment. Furthermore, the filtered internal and external circulating air entering the air conditioning unit 1 can reduce the risk of blockage of components such as the evaporator core 17 and the heater core 18 inside the air conditioning unit 1, which is beneficial to maintaining the performance of the air conditioning system 100 and extending the service life of the air conditioning system 100.

[0028] In some examples of this utility model, such as Figure 2 As shown, the filter structure 3 may include: a shell body 31, a cover plate 32, and a filter element 33. The shell body 31 defines an assembly space with one end open. The filter element 33 is assembled in the assembly space. The cover plate 32 is detachably disposed on the shell body 31 and covers the open end of the assembly space. The shell body 31 is fixed to the air inlet box 2. Both the shell body 31 and the cover plate 32 have ventilation holes 321 that communicate with the assembly space.

[0029] The housing body 31 defines an assembly space, one end of which is open. The filter element 33 is assembled within this space, and a cover plate 32 is placed over the open end to ensure stable assembly of the filter element 33. The cover plate 32 is detachably mounted on the housing body 31, for example, by snapping it onto the housing body 31 or by bolting it to the housing body 31. This design reduces the difficulty of disassembling the cover plate 32, thereby reducing the difficulty of maintaining and replacing the filter element 33 and improving its ease of maintenance.

[0030] The shell body 31 is fixed to the air inlet box 2. Both the shell body 31 and the cover plate 32 have ventilation holes 321 that communicate with the assembly space, so that the air can smoothly enter the assembly space through the cover plate 32, and after being filtered by the filter element 33, it flows out of the filter structure 3 through the ventilation holes 321, reducing the risk of wind obstruction by the shell body 31 and the cover plate 32, thereby facilitating the smooth flow of air in the air conditioning system 100.

[0031] In some examples of this utility model, such as Figure 2 As shown, filter element 33 includes a non-woven fabric structure.

[0032] The filter element 33 includes a non-woven fabric structure. This structure is loosely woven with high porosity, allowing it to simultaneously intercept both large surface particles and deep-seated fine particles. This significantly improves the filtration efficiency of the filter element 33, ensuring the quality of the exhaust air while effectively preventing performance degradation caused by clogging. The non-woven fabric structure also possesses high strength, high resilience, and tear resistance, maintaining the integrity of the filter element 33 even after long-term use. Furthermore, the non-woven fabric structure provides a larger dirt-holding capacity, extending the filter element 33's replacement cycle and reducing vehicle maintenance costs.

[0033] In some examples of this utility model, such as Figure 1 As shown, the air intake box 2 and the air conditioning unit 1 are arranged along the first direction, which is the width direction of the vehicle.

[0034] Among them, the air inlet box 2 and the air conditioning unit 1 are arranged along the first direction, that is, the first direction is Figure 1 The Y direction is the width direction of the vehicle. This arrangement allows for a reasonable layout of the air intake box 2 and the air conditioning unit 1. The air conditioning system 100 can be reduced by about 140mm along the first direction, which helps to reduce the size of the air conditioning system 100. This significantly improves the interior layout and space of the dashboard, effectively increasing the user's foot or leg space. In addition, it can also reduce the space occupied by the air conditioning system 100 in the passenger compartment, which helps to increase the passenger compartment space and thus improve the vehicle's ride comfort.

[0035] In some examples of this utility model, such as Figure 3 As shown, the air conditioning unit 1 may include: an air supply device 12 and an air distribution box 13. The air supply device 12 has an air inlet 11 and an air supply device outlet 121. The air distribution box 13 defines an air distribution channel 131 and has multiple air outlets 132. Each air outlet 132 is selectively opened or closed. The air distribution channel 131 connects the air supply device outlet 121 and the multiple air outlets 132.

[0036] The air supply device 12 has a main unit air inlet 11 and an air supply device outlet 121. The air distribution box 13 defines an air distribution channel 131 that communicates with the air supply device outlet 121. The air distribution box 13 has multiple air outlets 132. For example, the air distribution box 13 has two, three or more air outlets 132. This application takes the air outlets 132 including a defrost air outlet 133, a face air outlet 134 and a foot air outlet 135 as an example. Each air outlet 132 is selectively opened or closed so that the air conditioning system 100 can realize different air blowing functions, such as defrosting, face blowing or foot blowing functions. The air distribution channel 131 connects the air supply device outlet 121 and multiple air outlets 132 so that air energy enters the air distribution box 13 from the air supply device 12 through the air supply device outlet 121 and flows out of the corresponding air outlet 132 through the air distribution channel 131 to realize the function of the air conditioning system 100.

[0037] In some examples of this utility model, such as Figure 1 As shown, the air supply device 12 and the air distribution box 13 are arranged along the second direction, which is the length direction of the vehicle.

[0038] Among them, the air supply device 12 and the air distribution box 13 are arranged along the second direction, that is, the second direction is Figure 1 The X direction is the direction of the vehicle's length, and the second direction is the direction of the vehicle's length. This arrangement allows for a reasonable arrangement of the air supply device 12 and the air distribution box 13, which helps to reduce the size of the air conditioning system 100. It significantly improves the interior layout and space of the dashboard, effectively increases the user's foot or leg space, and further enhances the passenger cabin space, thereby improving the vehicle's ride comfort.

[0039] In some examples of this utility model, such as Figures 1-3 As shown, the air conditioning unit 1 may also include: multiple arc-shaped dampers 14, which are rotatably disposed in the air distribution channel 131. Through the cooperation of multiple arc-shaped dampers 14, each air outlet 132 can be selectively opened or closed.

[0040] The air conditioning unit 1 may also include multiple arc-shaped dampers 14, for example, two, three or more arc-shaped dampers 14. This application takes multiple arc-shaped dampers 14 including a heating and cooling damper 141, a first mode damper 142 and a second mode damper 143 as an example for illustration. The air conditioning unit 1 may also include a heating and cooling damper motor 15 and a mode damper motor 16. The heating and cooling damper 141 is driven by the heating and cooling damper motor 15, and the first mode damper 142 and the second mode damper 143 are both driven by the mode damper motor 16. Multiple arc-shaped dampers 14 can be rotatably arranged in the air distribution channel 131. Through the cooperation of multiple arc-shaped dampers 14, each air outlet 132 can be selectively opened or closed.

[0041] Specifically, when the air conditioning system 100 needs cooling, the hot and cold air damper motor 15 drives the hot and cold air damper 141 to rotate, so that the hot and cold air damper 141 blocks the warm air core 18. At this time, the air passes through the evaporator core 17, and the air temperature drops. When the air conditioning system 100 needs heating, the hot and cold air damper motor 15 drives the hot and cold air damper 141 to rotate, so that the hot and cold air damper 141 blocks the evaporator core 17. At this time, the air passes through the warm air core 18, and the air temperature rises. Furthermore, the hot and cold air damper motor 15 can also drive the hot and cold air damper 141 to rotate to partially block the evaporator core 17 and partially block the warm air core 18. The air temperature can be flexibly adjusted by adjusting the rotation angle of the hot and cold air damper 141.

[0042] When the air conditioning system 100 needs to blow air onto the feet, the mode damper motor 16 drives the first mode damper 142 to rotate, so that the first mode damper 142 simultaneously blocks the defrost air outlet 133 and the face air outlet 134, and the foot air outlet 135 opens. At this time, the temperature-controlled air is blown out through the foot air outlet 135. When the air conditioning system 100 needs to blow air onto the face, the mode damper motor 16 drives the first mode damper 142 to rotate, so that the first mode damper 142 blocks the foot air outlet 135, and drives the second mode damper 143 to rotate, so that the defrost air outlet 133 blocks the defrost air outlet 133, and the face air outlet 134 opens. At this time, the temperature-controlled air is blown out through the face air outlet. When the air conditioning system 100 needs to defrost, the mode damper motor 16 drives the first mode damper 142 to rotate so that the first mode damper 142 blocks the foot air outlet 135, and drives the second mode damper 143 to rotate so as to block the face air outlet 134. The defrost air outlet 133 opens, and the temperature-adjusted air is blown out through the defrost air outlet 133.

[0043] In some examples of this utility model, such as Figure 5 As shown, the arc-shaped damper 14 may include an arc-shaped shielding part 144 and two mounting parts 145. The two mounting parts 145 are opposite to each other and spaced apart, and both mounting parts 145 are rotatably mounted on the air distribution box 13. The arc-shaped shielding part 144 is connected between the two mounting parts 145 and is used to shield the corresponding air outlet 132.

[0044] The arc-shaped shielding part 144 and the two mounting parts 145 can be fixedly connected by, but not limited to, integral molding, snap-fit ​​connection, etc. The two mounting parts 145 are opposite and spaced apart, and both mounting parts 145 are rotatably mounted on the air distribution box 13. The arc-shaped shielding part 144 is connected between the two mounting parts 145. When the two mounting parts 145 rotate relative to the air distribution box 13, they can drive the arc-shaped shielding part 144 to shield the corresponding air outlet 132, thereby allowing the air conditioning system 100 to be adjusted to different operating modes. By setting the arc-shaped damper 14, the operating trajectory and required space of the arc-shaped damper 14 can be reduced while achieving the function of shielding the corresponding air outlet 132, effectively reducing the size of the air conditioning system 100. Furthermore, the arc-shaped shielding part 144 and the mounting parts 145 can form a grille 146 structure. This setting can improve the strength and durability of the arc-shaped damper 14, thereby extending the service life of the arc-shaped damper 14.

[0045] According to the present invention, the vehicle includes an air conditioning system 100 of the vehicle described in the above embodiments.

[0046] The air conditioning system 100 may also include a throttle valve 4 and a drip pipe 5. The throttle valve 4 is located in the air conditioning unit 1, which is beneficial for regulating air volume and speed. The drip pipe 5 is located in the air conditioning unit 1, and when the air conditioning system 100 is working, the condensate in the air conditioning unit 1 can be discharged through the drip pipe 5, reducing the risk of malfunction due to water accumulation and extending the service life of the air conditioning system 100. The air conditioning system 100 can meet the needs of both traditional energy vehicles and new energy vehicles, and can be matched with different thermal management system solutions, such as heat pump (WPTC) and non-heat pump (APTC). By placing the filter structure 3 inside the air inlet channel 21 and fixing it to the air inlet box 2, both the internal and external circulating air can be filtered by the filter structure 3 when passing through the air inlet channel 21, thereby improving the air quality of the passenger compartment. Furthermore, the filtered internal and external circulating air entering the air conditioning unit 1 can reduce the risk of blockage of components such as the evaporator core 17 and the heater core 18 inside the air conditioning unit 1, which is beneficial to maintaining the performance of the air conditioning system 100 and extending the service life of the air conditioning system 100.

[0047] In some examples of this utility model, the vehicle is a commercial vehicle.

[0048] The air conditioning system 100 of this application is arranged with the air inlet box 2 and the air conditioning host 1 along the first direction, the air supply device 12 and the air distribution box 13 along the second direction, and the arc-shaped air damper 14. This greatly reduces the space volume of the air conditioning system 100. Considering the space and layout characteristics of the dashboard of commercial vehicles, the air conditioning system 100 can be placed in the middle of the dashboard, thus developing a brand-new centrally located air conditioning system 100. Furthermore, this application has undergone simulation and bench testing, and its performance is no less than or even better than the existing split structure. The air conditioning system 100 is fully developed and feasible.
