Description

Technical Field

[0001] The invention relates to the technical field of automobile air conditioners, and in particular to a modular air conditioner assembly. Background Art

[0002] The air-conditioning assembly is the core component of the automobile air-conditioning system. To develop a new air-conditioning assembly, the mold fee is about 5 million to 6 million, the testing fee is about 3 million to 4 million, and the standard development cycle is 18 months.

[0003] The general technical design of the air-conditioning assembly adapted to the traditional domestic fuel version is: left-hand drive models, the evaporator uses refrigerant for cooling, the heater core uses engine coolant for heating, and the external plastic shell of the entire air-conditioning assembly is a whole. At present, various technologies of new energy are flourishing, the shape of the dashboard is becoming more and more diverse, and the export vehicles are also showing a blowout development. Therefore, the demand for air-conditioning assemblies has become diverse, such as: the demand for right-hand drive models of export vehicles, the indoor condenser is heated by refrigerant, the air PTC is heated by converting electrical energy into thermal energy, the thinning of the dashboard, etc. Often, a mature air-conditioning assembly needs to be redeveloped because it is adapted to different new energy power forms or different dashboard shapes. The cost starts at more than 1 million and the cycle starts at one year. The development cost is high and the development cycle is long.

[0004] In order to solve this technical problem, the prior art proposes an HVAC assembly structure of an automobile air conditioning system, which includes an air inlet box assembly, an air blower assembly, and an evaporator box assembly, which are fixedly connected by screws on the surface of the shell, and are interconnected through air ducts inside. The structure adopts a modular design, with a small overall structure and complete functions. By adding, removing or replacing parts, it can adapt to the cab air outlet design and HVAC function requirements of different models, solving the problem that the existing automobile air conditioning system HVAC is large in size, and the cab air outlet design and HVAC function requirements of different models are different, and the HVAC needs to be redesigned, which can effectively save design costs and time. However, this air conditioning system also has some problems. The air outlet assembly that matches the cab air outlet duct is designed on the upper shell of the evaporator box. As for how the air outlet is connected to the cab air outlet duct, there is no explanation. In fact, there are many different cab air outlet structures, and the air outlet structures of different models are completely different. How to connect and adapt the evaporator shell and the cab air outlet duct is the focus of the air conditioning system design. How to adapt the air conditioning system to different cab air outlet ducts is a problem that needs to be considered, but the above scheme does not actually solve this technical problem. Moreover, the above scheme also has problems in design structure. The above air conditioning system is an air inlet box assembly connected to a blower assembly, and finally connected to the evaporator box assembly together. The air inlet box assembly and the blower assembly are on one side of the evaporator box assembly. In actual application, this structure can only be applied to a vehicle with one steering direction. Once the steering direction is changed, the air conditioning system cannot be adapted, and its scope of use is relatively limited. Summary of the invention

[0015] The advantages of the present application are as follows: 1. The present application divides the air-conditioning assembly into an air intake block, an air blower block, a heat exchange block and an air distribution block, and adjacent blocks are connected by standard interfaces. Such a design structure only needs to adjust the structure of the docking part of a certain block with the vehicle body according to actual needs when adapting to the vehicle model, and the structure of other blocks can remain unchanged. Whether it is adapting from a left-hand drive vehicle model to a right-hand drive vehicle model, or adapting the air duct interface on the vehicle dashboard and the auxiliary instrument panel, and the adaptation of the vehicle model air intake structure, the air-conditioning assembly of the present application can achieve the desired effect by adjusting a small part of the structure of a certain block, without the need to design the mold for the entire air-conditioning assembly, which greatly reduces the mold opening cost, test cost, and development cost of the air-conditioning assembly; and because standard interfaces are used for docking adjacent blocks, no matter how the block is adapted to different vehicle requirements, its interface can remain unchanged, so there are very few parts on the block that need to be adjusted, which reduces the difficulty of redesigning the mold. During actual assembly and assembly, the standard interface can also well assemble adjacent blocks together to form the required air-conditioning assembly, and the overall structure is simple and extremely convenient to use; 2. The present application connects the air inlet block and the air blower block together through the first standard interface and the second standard interface. The connecting tube on the first standard interface corresponds to the first connecting pin on the second standard interface one by one. The first connecting pin can be easily inserted into the connecting tube, and they can be well connected to each other. It is very convenient to assemble. It only needs to drive bolts into the connecting through holes and screw holes to stably fix the air inlet block and the air blower block together. The first standard interface and the second standard interface are connected, which facilitates the blower in the air blower block to enter the air through the air inlet block. 3. The first connecting pin of the present application is provided with a plurality of rib structures on the outer side of its circumference. The rib structures can be pressed against the inner wall of the connecting tube after the first connecting pin is inserted into the connecting tube, so that the first connecting pin and the connecting tube can be stably connected together. At the same time, the rib structures can center the first connecting pin on the connecting tube, align the through hole of the first connecting pin with the screw hole on the connecting tube in the axial direction, which is convenient for subsequent driving of bolts to fix the two together, and facilitate the assembly between the air intake block and the air blower block; 4. The present application connects the third standard interface on the air blast block with the fourth standard interface on the heat exchange block. The second connecting pin on the third standard interface corresponds to the connecting plate on the fourth standard interface. The connecting plate is a plate-like structure protruding from the heat exchange block. The second connecting pin can be easily inserted into the pin hole of the connecting plate from the side, so that the air blast block can be easily fixed to the heat exchange block. The overall assembly is very simple. 5. The second connecting pin of the present application is a tapered cross pin structure. During actual assembly, the small end of the pin body can be easily inserted into the corresponding pin hole, which allows a certain degree of assembly error, facilitates the assembly between the air blast block and the heat exchange block, and reduces the difficulty of docking and assembly between the second connecting pin and the connecting plate; 6. The present application splits the air distribution block into two parts, a first air distribution component and a second air distribution component. The two air distribution components correspond to the air inlet ducts of the instrument panel and the sub-instrument panel respectively. The two air distribution components are connected to the heat exchange component separately, and can adapt to different instrument panel air duct interface structures, so as to facilitate adaptive design adjustment according to the instrument panel air duct interface structure. The adjustment of a single component is simpler, and the adaptability to the passenger compartment of different models is better. 7. The present application connects the first standard interface of the heat exchange block through the fifth standard interface of the first air distribution component. The fifth standard interface and the seventh standard interface are standard interfaces that do not need to be changed. When adapting to different models, it is only necessary to adjust the structure of the connection between the first air distribution component and the instrument panel air duct interface. The heat exchange block only needs to replace the internal components in the same shell, and there is no need to make any adjustments to the shell of the heat exchange block itself. The adaptability change is very small, and the combined structure of the first positioning pin and the first positioning hole is used for assembly, which greatly reduces the difficulty of assembly of the two, and the actual assembly is extremely convenient; 8. The present application connects the eighth standard interface on the second air distribution component with the sixth standard interface on the heat exchange block. The second air distribution component corresponds to the air duct interface on the sub-instrument panel. The assembly structure is simple. The second positioning pin can be easily inserted into the second positioning hole to complete the connection and fixation between the second air distribution component and the heat exchange block, so that the air outlet of the heat exchange block is blown to the air duct of the sub-instrument panel through the second air distribution component. The overall structure is simple and easy to assemble. 9. The first positioning pin of the present application is a tapered cross pin structure, which can be easily inserted into the corresponding first positioning hole during actual assembly, and a certain degree of assembly processing error can be allowed. Moreover, the assembled first air distribution component and the heat exchange block can be accurately docked, and the formed gas passage structure facilitates the smooth flow of gas; 10. The second positioning pin of the present application is a tapered cross pin structure, which can be easily inserted into the corresponding second positioning hole during actual assembly. It can allow a certain degree of assembly and processing errors between the sixth standard interface and the eighth standard interface, making it convenient to assemble the second air distribution component to the heat exchange block, and the overall assembly is very simple.

[0016] The air-conditioning assembly of the present application has a simple structure and adopts a modular design concept. When adapting to different vehicle structures, it is only necessary to adjust the structure connected to the vehicle body. There is no need to redesign and adjust the entire air-conditioning assembly, which reduces the difficulty of air-conditioning assembly design and greatly reduces the mold opening cost, testing cost, and development cost of the air-conditioning assembly, and has great promotion value.

In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0021] The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] The present application relates to a modular air-conditioning assembly. The air-conditioning assembly of the present application adopts a modular design structure, and the various parts in the air-conditioning assembly are divided according to their functions, namely, an air intake block, an air blower block, a heat exchange block and an air distribution block. The air intake block is connected to the body sheet metal to take in air from the outside of the body. The air blower block is a structure equipped with a blower. The blower draws air from the air intake block and then discharges it to the heat exchange block. The heat exchange block is the core block component of the air-conditioning assembly. The gas discharged from the air blower block undergoes heat exchange in the heat exchange block. Finally, the heat exchange block discharges the gas that has completed heat exchange into the passenger compartment through the air distribution block, completing the air conditioning control process. Since the air-conditioning assembly of the present application is divided into multiple components according to their functions, the air intake block, heat exchange block and air distribution block connected to the vehicle body can only be adjusted according to the vehicle structure during the design process. The other positions can be left unchanged. In this way, the parts that need to be adjusted during the design process are greatly reduced, and the design difficulty and mold opening difficulty are greatly reduced. The adjacent blocks of the present application are connected and fixed using standard interfaces, and the standard interfaces do not need to be adjusted. On the one hand, during the design process, a unified standard interface can be used without making major adjustments, which is convenient for design, mold opening and testing. On the other hand, the standard interface facilitates the assembly between adjacent blocks, greatly improving the efficiency of the installation and assembly of the air-conditioning assembly.

[0023] Specifically, Figures 1 to 9 As shown, a modular air conditioning assembly of the present application includes an air intake block 1, an air blower block 2, a heat exchange block 3 and an air distribution block. The air intake block 1 is a hollow shell structure. The inlet side of the air intake block 1 is provided with a body interface connected to the body sheet metal, and the outlet side of the air intake block 1 is provided with a first standard interface 11. The air intake block 1 is actually a hollow air duct structure connected to the body sheet metal at one end and connected to the air blower block at the other end. The air intake block 1 facilitates the air blower block 2 to inhale air from the outside of the body. The body interface of the air intake block 1 corresponds to the body sheet metal structure of the vehicle model. Therefore, in the design process, it is only necessary to adjust the body interface of the air intake block 1 according to the body sheet metal structure of the adapted vehicle model, and no changes are required to be made to other parts of the air intake block 1 except the body interface.

[0024] The blower block 2 is a hollow shell structure with a blower installed. A second standard interface 21 that is connected and fixed to the first standard interface 11 is provided on one side of the blower block 2, and a third standard interface 22 is provided on the other side of the blower block 2. A blower is installed inside the blower block 2, and the blower can be connected to the air intake block 1 through the channel structure of the second standard interface 21 connected to the first standard interface 11, so that the blower can inhale air from the outside through the air intake block 1. The blower block 2 is connected to the air intake block 1 through the first standard interface 11, and is connected to the heat exchange block through the third standard interface 22. The blower block 2 itself is not directly connected to the vehicle body. In the design process of the air conditioning assembly, the blower block 2 can adapt to a variety of vehicle models. Only when the blower of the air conditioning assembly needs to be adjusted, the installation structure of the blower in the shell of the blower block 2 needs to be redesigned, and the shell of the blower block 2 itself does not need to be adjusted except for the installation structure of the blower.

[0025] The heat exchange block 3 is a shell structure connected to the vehicle body and having a heat exchange component inside. The heat exchange block 3 includes a fourth standard interface 31 that is connected and fixed to the third standard interface 22. At least one docking interface is also provided on the heat exchange block 3. The heat exchange block 3 is directly connected to the vehicle body. The structure of the connection part between the heat exchange block 3 and the vehicle body is adaptively adjusted according to the vehicle body. Other structural parts of the shell of the heat exchange block 3 do not need to be adjusted. The heat exchange block 3 is the core component of the entire air conditioning assembly. A heat exchange structure is installed inside its shell. The shell of the heat exchange block 3 is connected to the third standard interface 22 on the blower block 2 through the fourth standard interface 31, that is, the shell inlet of the heat exchange block 3 is connected to the shell outlet of the blower block 2, and the exhaust gas of the blower block 2 enters the heat exchange block 3 for heat exchange.

[0026] The air distribution block is a shell structure with interfaces connected with the air ducts on the instrument panel and the sub-instrument panel. The air distribution block is provided with a docking structure which is connected with and fixed to the docking interface. The air distribution block is a structure corresponding to the air inlet duct interface of the instrument panel in the cab of the vehicle body. The air distribution block is also connected to the heat exchange block through the docking interface and the docking structure. The docking interface and the docking structure are also standard structures. In actual design, it is only necessary to adjust the part of the air distribution block corresponding to the instrument panel air duct interface, and other structures on the air distribution block do not need to be changed, so it can adapt to different vehicle structure.

[0027] When the air-conditioning assembly of the present application is actually assembled: the air intake block 1 and the air blower block 2 are connected together through the first standard interface 11 and the second standard structure 21, the air blower block 2 and the heat exchange block 2 are connected together through the third standard interface 22 and the fourth standard interface 31, and the air distribution block and the heat exchange block 3 are assembled together through the docking structure and the docking interface to form an air-conditioning assembly; then the vehicle body interface of the air intake block 1 is connected to the sheet metal on the vehicle body, the heat exchange block 3 is fixed to the corresponding connection point on the vehicle body, and the air distribution block is connected to the air duct interface on the vehicle body dashboard to complete the assembly of the air-conditioning assembly and the vehicle body.

[0028] In some embodiments of the present application, the first standard interface 11 and the second standard interface 21 are optimized. Specifically, Figure 5 and 6 As shown, the first standard interface 11 and the second standard interface 21 of the present embodiment are respectively arranged on one side of the shell of the air inlet block 1 and the shell of the air blower block 2, the first standard interface 11 corresponds to the air outlet of the shell of the air inlet block 1, and the second standard interface 21 corresponds to the air inlet of the shell of the air blower block 2. After the first standard interface 11 and the second standard interface 21 are connected together, the air outlet of the air inlet block 1 is connected to the air inlet of the air blower block 2.

[0029] A plurality of connecting tubes 12 are arranged on the circumferential outer side of the first standard interface 11 (in fact, a plurality of connecting tubes 12 are arranged on the shell side of the air inlet block 1 where the first standard interface 11 is arranged, such as Figure 5 As shown, three connecting cylinders 12 are arranged on the first standard interface 11 of this embodiment), the connecting cylinder 12 is a hollow cylindrical structure with one side open and the other side closed, a through hole for bolts to pass through is opened on the closed side of the connecting cylinder 12, the connecting cylinder 12 is circumferentially connected to the first standard interface 11 through a groove structure, the groove structure extends radially along the first standard interface 11, and the connecting cylinder 12 is fixed to one end of the groove structure away from the first standard interface 11.

[0030] like Figure 6 As shown, a plurality of first connecting pins 23 corresponding to the connecting tubes 12 are arranged on the circumferential outer side of the second standard interface 21. The first connecting pin 23 is a hollow pin-shaped structure with one end fixed to the air blast block 2 and the other end provided with a screw hole. Similarly, the second standard interface 21 of this embodiment is a circular opening structure corresponding to the first standard interface 11. The first connecting pins 23 arranged on the second standard structure 21 correspond to the connecting tubes 12 on the first standard interface 11 one by one, and there are also three of them.

[0032] In addition, in order to facilitate the docking between the connecting tube 12 and the first connecting pin 23, a plurality of ribs 24 are provided on the circumferential outer side of the first connecting pin 23 of the present embodiment. The plurality of ribs 24 are arranged at equal intervals along the circumferential direction of the first connecting pin 23. The ribs 24 are strip structures which are arranged axially along the first connecting pin 23 and protrude from the circumferential surface of the first connecting pin 23. When the first connecting pin 23 is inserted into the connecting tube 12, the ribs 24 are pressed against the inner side of the circumference of the connecting tube 12.

[0033] When the first connecting pin 23 is inserted into the connecting cylinder 12, the ribs 24 are pressed against the inner side of the circumference of the connecting cylinder 12, so that the first connecting pin 23 can be stably restricted in the connecting cylinder 12, and the through hole on the connecting cylinder 12 is conveniently aligned with the screw hole on the first connecting pin 23. At the same time, the ribs 24 tightened in the connecting cylinder 12 can limit the shaking of the first connecting pin 23 in the connecting cylinder 12, so that the connection between the air intake block 1 and the air blowing block 2 is more stable.

[0034] The first standard interface 11 and the second standard interface 21 can be designed as a structure with fixed specifications and dimensions, that is, in the subsequent development and design process, the first standard interface 11 and the second standard interface 21 are no longer adjusted, and only the parts of the air intake block 1 and the air blower block 2 corresponding to the vehicle body need to be adjusted.

[0035] In some other embodiments of the present application, the third standard interface 22 and the fourth standard interface 31 are optimized. The third standard interface 22 and the fourth standard interface 31 are structures for connecting the air blast block 2 and the heat exchange block 3. Figures 6 and 7 As shown, the air blast block 2 is fixed to the first side of the heat exchange block 3, and the third standard interface 22 is the air outlet of the air blast block 2. Figure 7 As shown, the fourth standard interface 31 is the air inlet of the heat exchange block 3 , and the third standard interface 22 is connected to the fourth standard interface 31 , that is, the air outlet of the air blowing block 2 is connected to the air inlet of the heat exchange block 3 .

[0036] A plurality of second connecting pins 25 are provided at the third standard interface 22. The second connecting pins 25 are pin-shaped structures with one end fixed to the air blower block 2 and the other end extending along the axial direction of the blower. In fact, the second connecting pins 25 are provided on the side of the shell of the air blower block 2 corresponding to the first side of the heat exchange block 3. The second connecting pins 25 are arranged along the axis of the blower and parallel to the first side of the heat exchange block 3.

[0037] The fourth standard interface 31 is provided with a connecting plate 32 corresponding to the second connecting pin 25. The connecting plate 32 is a plate-like structure with a pin hole and one end fixed to the heat exchange block 3. The connecting plate 32 is a plate-like structure vertically fixed to the first side of the shell of the heat exchange block 3.

[0038] During actual assembly, the second connecting pin 25 is aligned with the pin hole on the connecting plate 32 along the axial direction of the blower, and then the second connecting pin 25 is inserted into the pin hole along the axial direction of the blower to fix the air blowing block 2 and the heat exchange block 3 together.

[0039] In order to facilitate the assembly of the second connecting pin 25 and the pin hole on the connecting plate 32, as shown in FIG. Figure 6 As shown, the second connecting pin 25 of this embodiment is a conical cross pin with a cross-shaped cross section, one end of which is fixed to the air blast block 2 and one end of which is connected to the connecting plate 32. After the small head end of the conical cross pin is inserted into the pin hole, the air blast block 2 can be automatically centered during the insertion process, so that the third standard interface 22 and the fourth standard interface 31 are accurately aligned together.

[0040] In a further embodiment of the present application, the present embodiment optimizes the above-mentioned wind distribution block, specifically, Figures 1 to 4 As shown in Figures 8 and 9, the air distribution block of this embodiment includes a first air distribution component 4 and a second air distribution component 5. The first air distribution component 4 is a hollow shell structure having an interface for docking with the instrument panel air duct, and the first air distribution component 4 is provided with a seventh standard interface 41 that is docked, connected and fixed to the fifth standard interface 33 in the docking interface of the heat exchange block 3; the second air distribution component 5 is a hollow shell structure having an interface for docking with the auxiliary instrument panel air duct, and the second air distribution component 5 is provided with an eighth standard interface 51 that is docked, connected and fixed to the sixth standard interface 34 in the docking interface of the heat exchange block 3.

[0041] The first air distribution component 4 is arranged on the first side of the shell of the heat exchange block 3, and the second air distribution component 5 is arranged on the second side of the shell of the heat exchange block 3. The first side and the second side of the shell of the heat exchange block 3 are two sides arranged opposite to each other. That is, two air outlets are arranged on the shell of the heat exchange block 3 of this embodiment, and the two air outlets are respectively located on the first side and the second side of the heat exchange block 3, and are connected and docked with the first air distribution component 4 and the second air distribution component 5 respectively.

[0042] The first air distribution component 4 corresponds to the instrument panel air duct, and the second air distribution component 5 corresponds to the auxiliary instrument panel air duct. When designing, only the position of the first air distribution component 4 corresponding to the instrument panel air duct interface and the position of the second air distribution component 5 corresponding to the auxiliary instrument panel air duct interface need to be adaptively adjusted and designed, and other structures of the first air distribution component 4 and the second air distribution component 5 are not adjusted, so as to adapt to the development and design of new models.

[0043] The seventh standard interface 41 on the first air distribution component 4 is the air inlet of the first air distribution component 4, and the fifth standard interface 33 of the heat exchange block 3 is one of the air outlets of the heat exchange block 3. The first air distribution component 4 is connected to the heat exchange block 3 through the connection between the seventh standard interface 41 and the fifth standard interface 33. Specifically, Figure 7 As shown, a plurality of first positioning pins 35 are provided at the fifth standard interface 33. The first positioning pin 35 is a pin-shaped structure with one end fixed on the heat exchanger block 3 and the other end extending toward the first air distribution component 4. A plurality of positioning plates 42 are provided on the seventh standard interface 41. The positioning plates 42 are provided with first positioning holes 43 corresponding to the first positioning pins 35.

[0044] When assembling the first air distribution component 4 and the heat exchange block 3, move the seventh standard interface 41 of the first air distribution component 4 to the first side of the shell of the heat exchange block 3, align the first positioning hole 43 on the shell of the first air distribution component 4 with the first positioning pin 35 on the heat exchange block 3, and then insert the first positioning pin 35 into the corresponding first positioning hole 43 to fix the heat exchange block 3 and the first air distribution component 4 into one.

[0045] In order to facilitate the assembly of the first air distribution component 4 and the heat exchange block 3, the structure of the first positioning pin 35 is optimized in this embodiment. Figure 7 As shown, the first positioning pin 35 is a conical cross pin with a cross-shaped cross section, which is small at one end away from the heat exchange block 3 and large at one end close to the heat exchange block 3. The first positioning pin 35 of the conical cross pin structure can be inserted into the first positioning hole 43, and a certain assembly and processing error is allowed. After the first positioning pin 35 is inserted into the first positioning hole 43, it can be automatically aligned, so that the fifth standard interface 33 and the seventh standard interface 41 are accurately aligned.

[0046] The eighth standard interface 51 on the second air distribution component 5 is the air inlet of the second air distribution component 5, and the sixth standard interface 34 on the heat exchange block 3 is another air outlet on the heat exchange block 3. The second air distribution component 5 is connected to the heat exchange block 3 through the eighth standard interface 51 and the sixth standard interface 34. Figure 7 As shown, a plurality of second positioning holes 36 are provided at the sixth standard interface 34 , and a plurality of second positioning pins 52 are provided at the eighth standard interface 51 . The second positioning pin 52 is a pin-shaped structure with one end fixed on the second air distribution component 5 and the other end extending toward the heat exchange block 3 .

[0047] When assembling the second air distribution component 5 and the heat exchange block 3, move the eighth standard interface 51 of the second air distribution component 5 to the second side of the shell of the heat exchange block 3, align the second positioning pin 52 on the shell of the second air distribution component 5 with the second positioning hole 36 on the shell of the heat exchange block 3, and then insert the second positioning pin 52 into the corresponding second positioning hole 36 to fix the heat exchange block 3 and the second air distribution component 5 into one.

[0048] In order to facilitate the connection between the second positioning pin 52 and the second positioning hole 36, the structure of the second positioning pin 52 is optimized in this embodiment. Fig. 9 As shown, the second positioning pin 52 is a cross-shaped tapered cross pin with a small cross-section at one end away from the second air distribution component 5 and a large cross-section at one end close to the second air distribution component 5. The second positioning pin 52 of the tapered cross pin structure can be inserted into the second positioning hole 36, and a certain assembly and processing error can be allowed. After the second positioning pin 52 is inserted into the second positioning hole 36, it can be automatically aligned, so that the sixth standard interface 34 and the eighth standard interface 51 are accurately aligned.

[0049] When assembling the air conditioner assembly, the side of the housing of the air inlet block 1 provided with the first standard interface 11 is aligned with the side of the housing of the air blower block 2 provided with the second standard interface 21, and the first connecting pin 23 is inserted into the connecting cylinder 12 from the opening on one side of the connecting cylinder 12. After all the first connecting pins 23 are inserted into the corresponding connecting cylinder 12, bolts are driven into the aligned through holes and screw holes to fix the air inlet block 1 and the air blower block 2 together. Align the second connecting pin 25 with the pin hole on the connecting plate 32 along the axial direction of the blower, and then insert the second connecting pin 25 into the pin hole along the axial direction of the blower to fix the air blowing block 2 and the heat exchange block 3 together; Move the seventh standard interface 41 of the first air distribution component 4 to the first side of the shell of the heat exchange block 3, align the first positioning hole 43 on the shell of the first air distribution component 4 with the first positioning pin 35 on the heat exchange block 3, and then insert the first positioning pin 35 into the corresponding first positioning hole 43 to fix the heat exchange block 3 and the first air distribution component 4 together; Move the eighth standard interface 51 of the second air distribution component 5 to the second side of the shell of the heat exchange block 3, align the second positioning pin 52 on the shell of the second air distribution component 5 with the second positioning hole 36 on the shell of the heat exchange block 3, and then insert the second positioning pin 52 into the corresponding second positioning hole 36 to fix the heat exchange block 3 and the second air distribution component 5 together; Then assemble the assembled air-conditioning assembly to the vehicle body, connect the vehicle body interface of the air intake block 1 to the vehicle body sheet metal, fix the heat exchange block 3 to the vehicle body through the vehicle body fixing point, connect the first air distribution component 4 to the instrument panel air duct interface, connect the second air distribution component 5 to the auxiliary instrument panel air duct interface, and complete the assembly of the air-conditioning assembly.

[0050] The modular air conditioning assembly of this application has been applied, and the application scenarios are as follows: Application scenario 1: In order to meet the needs of the export market, it is necessary to develop a right-hand drive model based on a left-hand drive car, and the layout of the air inlet will interfere with the pedal mechanism, so it needs to be rearranged and designed and developed. The traditional solution is to develop the air-conditioning assembly in a mirror image. In addition to some parts that can be shared, the mold fee for the parts developed by the mirror image design is about 4 million, and the development cycle is more than 1 year. However, after the air-conditioning assembly is divided into 4 blocks, only one air intake block needs to be developed symmetrically, and the cost can be compressed to less than 500,000. The test only needs to be carried out on the air intake, and the development cycle can be completed in 5 to 6 months.

[0051] Application scenario 2: In the same series, a car with a larger wheelbase appears, and the air volume demand increases, resulting in the need to replace the air conditioner blower motor with a higher power. In this case, we only need to redesign and develop the blower module, and the mold cost can be reduced to less than 1 million, and the cycle can also be reduced to less than 6 months.

[0052] Application scenario 3: Traditional fuel vehicles are changed to direct cooling and direct heating pure electric vehicles. Traditional fuel vehicles use the engine coolant to heat through the heater core, while direct cooling and direct heating use the refrigerant to heat through the indoor condenser, and may also be matched with air PTC for auxiliary heating. This type of change only requires the development of a new heat exchange block to include the indoor condenser and air PTC, and the mold cost can also be compressed to less than 1 million, and the development cycle can be completed in about 6 months.

[0053] Application scenario 4: The shape of the dashboard changes, resulting in a change in the position of the air outlet that connects to the air conditioning assembly. If we redevelop it, the mold cost will be more than 2 million. However, if we only develop the air distribution module to adapt to the dashboard, the cost can be compressed to less than 300,000, and the development cycle can be completed in about 3 to 4 months.

[0054] Therefore, it is proved that the modular air-conditioning assembly of the present application produces huge benefits.
