Description

Technical Field

[0001] This utility model relates to the field of automotive parts design and manufacturing technology, and in particular to an automotive air conditioning unit mounting structure and an automotive air conditioning unit. Background Technology

[0002] Automotive air conditioning is a crucial system for regulating the interior environment of a vehicle. It primarily controls temperature, humidity, airflow speed, and air cleanliness to provide a comfortable environment for passengers. One of the core components of automotive air conditioning is the air conditioning unit, which typically includes components such as the air intake box, volute, and distribution box, used to draw in, distribute, and regulate the temperature of air. The air conditioning unit is usually fixed to the vehicle's body structure through multiple mounting points, which must withstand the weight of the unit and various loads during vehicle operation. The installation method of the air conditioning unit directly affects its stability, assembly efficiency, and overall vehicle cost.

[0003] Existing air conditioning unit installation methods are generally divided into final assembly and cabin assembly. Final assembly involves fixing the air conditioning unit to the front bulkhead assembly of the vehicle using multiple mounting points. This method leaves the air conditioning unit's center of gravity suspended outside the mounting points, causing these points to bear significant torque and potentially leading to insufficient strength. It is only suitable for lightweight two-core air conditioning units and lacks versatility. Cabin assembly, on the other hand, involves fixing the air conditioning unit to the dashboard crossbeam assembly and the front bulkhead assembly separately using multiple mounting points. While this method provides better stability as the center of gravity is located between the mounting points, it requires transferring the air conditioning unit to the supplier assembling the cabin for assembly. During assembly, the air conditioning unit is prone to sagging, requiring specialized tooling, resulting in higher overall vehicle costs, greater assembly difficulty, and a higher probability of error.

[0004] For hybrid commercial vehicles employing a three-core structure (such as combining an evaporator core, a heater core, and a PTC core), the air conditioning unit is heavy and has a rearward center of gravity. Using traditional final assembly methods would result in insufficient structural strength; using traditional cabin assembly methods would be too costly, difficult, and prone to errors. Therefore, there is an urgent need for an air conditioning unit installation structure design that can ensure structural strength while reducing costs and assembly difficulty. Utility Model Content

[0005] The present invention aims to provide an automotive air conditioning unit installation structure and an automotive air conditioning unit to solve the above-mentioned technical problems, and reduce costs and assembly difficulty while ensuring the strength of the installation structure.

[0006] To achieve the above objectives, the first aspect of this utility model provides an automotive air conditioning unit mounting structure, applicable to automotive air conditioning unit assembly processes. The automotive includes a front bulkhead assembly, a front floor assembly, and an integrated mounting bracket. The air conditioning unit includes a distribution box, an air intake box, and a volute. The integrated mounting bracket is fixed to the surface of the front floor assembly, and the volute is connected to both the distribution box and the air intake box. Wherein:

[0007] One side of the distribution box is connected to the front bulkhead assembly, and the other side is connected to the integrated mounting bracket; the front bulkhead assembly is connected to the air inlet box and the volute respectively.

[0008] The aforementioned automotive air conditioning unit mounting structure connects the other side of the distribution box to the integrated mounting bracket, thereby making the integrated mounting bracket and the front floor assembly serve as the rear support points of the automotive air conditioning unit. Compared to the final assembly method that only fixes the automotive air conditioning unit to the front bulkhead assembly of the vehicle, this structure can support the automotive air conditioning unit through the front bulkhead assembly on one side and the front floor assembly on the other side, forming a "front and rear enclosed" support. This distributes the weight of the automotive air conditioning unit, ensuring that the center of gravity of the air conditioning unit is located between the front bulkhead assembly and the front floor assembly, preventing the center of gravity from shifting backward, greatly reducing the supporting torque of the air conditioning unit, and ultimately improving the strength and stability of the automotive air conditioning unit mounting structure.

[0009] Furthermore, compared to the cabin assembly method that fixes the air conditioning unit to the dashboard crossbeam assembly and the front bulkhead assembly, the above-mentioned air conditioning unit mounting structure places the air conditioning unit on the integrated mounting bracket of the front floor assembly during assembly. This provides pre-support, forming a "sitting" installation that requires no manual assistance or the use of specialized tools (such as jacks). It is compatible with existing final assembly lines, has lower overall vehicle costs, is easier to assemble, and has a lower probability of error.

[0010] Preferably, the bottom of the dispensing box is provided with a first support foot, which extends outward relative to one side of the dispensing box, wherein:

[0011] The first support leg is connected to the integrated mounting bracket.

[0012] In this preferred embodiment, the first support leg extending outward from the distribution box is connected to the integrated mounting bracket to provide rear support for the distribution box and share the weight of the air conditioning unit with the front panel assembly. The extended design of the first support leg can optimize the torque distribution of the distribution box support structure, thereby preventing the center of gravity of the air conditioning unit from shifting forward or backward, and improving the strength and stability of the air conditioning unit installation structure.

[0013] Preferably, the bottom of the dispensing box is further provided with a second support leg, the second support leg extending outward relative to one side of the dispensing box, the second support leg being symmetrically arranged side by side with the first support leg, wherein:

[0014] The second support leg is connected to the integrated mounting bracket.

[0015] In this preferred embodiment, a second support foot is added to the first support foot, which together connects to the integrated mounting bracket to provide rear support for the distribution box and share the weight of the air conditioning unit with the front panel assembly. The side-by-side symmetrical structure further optimizes the moment distribution of the distribution box support structure, so that the weight of the air conditioning unit on one side of the support foot is evenly distributed on the first and second support feet, reducing the load on individual support feet, thereby further optimizing the moment distribution of the distribution box support structure, preventing the center of gravity of the air conditioning unit from shifting forward or backward, and further improving the strength and stability of the air conditioning unit installation structure.

[0016] Preferably, the first support leg has a first support hole, and the second support leg has a second support hole, wherein:

[0017] The first support foot is tightly connected to the integrated mounting bracket through the first support hole; the second support foot is tightly connected to the integrated mounting bracket through the second support hole.

[0018] This preferred embodiment, by opening the aforementioned support holes, enables the support feet to be tightly connected to the integrated mounting bracket via threaded connection or by fastener through-locking, thereby improving the connection strength between the support feet and the integrated mounting bracket, and enhancing the strength and stability of the air conditioning unit installation structure.

[0019] Preferably, the thickness of the first support foot and the second support foot is 10mm, and the width of the first support foot and the second support foot is 50mm.

[0020] In this preferred embodiment, the thickness of the first support foot and the second support foot is 10mm, and the width of the first support foot and the second support foot is 50mm. While ensuring that the volume of the first support foot and the second support foot meets the space required for the electric gun assembly method, the volume of the load weight is increased and the torque of the support foot is reduced, thereby improving the strength and stability of the air conditioning unit installation structure.

[0021] Preferably, the distribution box is provided with a first mounting foot, a second mounting foot, and a third mounting foot on one side, wherein:

[0022] The first mounting foot and the second mounting foot are close to the top of the distribution box and are symmetrically arranged; the third mounting foot is close to the bottom of the distribution box; the front panel assembly is connected to the first mounting foot, the second mounting foot and the third mounting foot respectively.

[0023] In this preferred embodiment, a first mounting foot, a second mounting foot, and a third mounting foot are respectively provided on the side of the distribution box near the front bulkhead assembly to connect with the front bulkhead assembly. The first mounting foot, the second mounting foot, and the third mounting foot are evenly distributed on the side of the distribution box near the front bulkhead assembly, which can distribute the weight load of the distribution box, thereby reducing the supporting moment of the distribution box. Together with the integrated mounting bracket connection on the other side of the distribution box, they share the weight of the automotive air conditioning box, improving the strength and stability of the air conditioning box installation structure.

[0024] Preferably, the air inlet box is symmetrically provided with a fourth mounting foot and a fifth mounting foot on both sides, wherein:

[0025] The fourth mounting foot extends outward relative to one side of the air inlet box, and the fifth mounting foot extends outward relative to the other side of the air inlet box; the front bulkhead assembly is connected to the fourth mounting foot and the fifth mounting foot respectively.

[0026] In this preferred embodiment, a fourth mounting foot and a fifth mounting foot are symmetrically arranged on both sides of the air intake box near the front bulkhead assembly to connect with the front bulkhead assembly. This can distribute the weight load of the air intake box, thereby reducing the supporting torque of the air intake box. Together with the front bulkhead assembly connection part and the integrated mounting bracket connection part at the distribution box, they share the weight of the automotive air conditioning box, improving the strength and stability of the air conditioning box installation structure.

[0027] Preferably, the volute is provided with a sixth mounting foot, wherein:

[0028] The sixth mounting foot extends outward relative to one side of the volute; the front bulkhead assembly is connected to the sixth mounting foot.

[0029] In this preferred embodiment, a sixth mounting foot is provided at one end of the volute near the front bulkhead assembly to connect with the front bulkhead assembly. This connection part, together with the front bulkhead assembly connection part at the distribution box, the integrated mounting bracket connection part at the distribution box, and the front bulkhead assembly connection part at the air intake box, works together to share the weight of the automotive air conditioning unit, thereby improving the strength and stability of the air conditioning unit installation structure.

[0030] A second aspect of this utility model provides an automotive air conditioning unit, applicable to the automotive air conditioning unit installation structure described in any one of the first aspects of this utility model. The automotive air conditioning unit includes a distribution box, an air intake box, and a volute, wherein the volute is connected to the distribution box and the air intake box respectively, wherein:

[0031] The bottom of the distribution box is provided with a first support foot and a second support foot. The first support foot and the second support foot extend outward relative to one side of the distribution box. The first support foot and the second support foot are symmetrically arranged side by side.

[0032] The other side of the dispensing box is provided with a first mounting foot, a second mounting foot and a third mounting foot. The first mounting foot and the second mounting foot are close to the top of the dispensing box and are symmetrically arranged. The third mounting foot is close to the bottom of the dispensing box.

[0033] The air inlet box is symmetrically provided with a fourth mounting foot and a fifth mounting foot on both sides. The fourth mounting foot extends outward relative to one side of the air inlet box, and the fifth mounting foot extends outward relative to the other side of the air inlet box.

[0034] The volute is provided with a sixth mounting foot, which extends outward relative to one side of the volute.

[0035] The aforementioned automotive air conditioning unit can be connected to the front floor assembly on one side of the vehicle via the first and second support feet, and to the front bulkhead assembly on the other side of the vehicle via the first, second, third, fourth, fifth, and sixth mounting feet. These eight connection points work together to distribute the weight of the air conditioning unit. Compared to the general assembly method that simply fixes the air conditioning unit to the front bulkhead assembly, this system allows the air conditioning unit to be supported by both the front bulkhead assembly on one side and the front floor assembly on the other, forming a "front and rear enclosed" support structure. This distributes the weight of the air conditioning unit, ensuring its center of gravity is located between the front bulkhead assembly and the front floor assembly, preventing rearward shift of the center of gravity, significantly reducing the supporting torque, and ultimately improving the strength and stability of the air conditioning unit's installation structure.

[0036] Preferably, the first support foot has a first support hole, and the second support foot has a second support hole; the first mounting foot has a first mounting hole, the second mounting foot has a second mounting hole, the third mounting foot has a third mounting hole, the fourth mounting foot has a fourth mounting hole, the fifth mounting foot has a fifth mounting hole, and the sixth mounting foot has a sixth mounting hole.

[0051] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that the following detailed descriptions are exemplary and intended to provide further detailed explanation of the present invention. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings, are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings are used to distinguish different objects, not to describe a particular order.

[0052] First, some of the terms used in this application will be explained to facilitate understanding by those skilled in the art.

[0053] (1) Front bulkhead assembly: Located between the driver's compartment and the front compartment (engine compartment or motor compartment), it is an important component of the vehicle body structure. Its main functions include: separating the driver's compartment from the front compartment, providing sound insulation and heat insulation; supporting components such as the instrument panel, air conditioning unit, and brake pedal; improving body rigidity and participating in the transmission of collision forces. In some possible embodiments, the "front bulkhead assembly" can be simplified to "front bulkhead".

[0054] (2) Front floor assembly: Located at the bottom of the vehicle body, below the cockpit, connecting the front bulkhead and the middle floor (generally extending from the foot pedal area to the front seat crossbeam), usually integrated with the central tunnel.

[0055] There are two installation methods for the air conditioning unit in existing vehicle models: final assembly and cabin assembly. The layout of the final assembly air conditioning unit is as follows: Figure 1 As shown, assembly points 4a, 4b, 4c, 4d, 4e, and 4f of the air conditioning unit are fixed to the front bulkhead assembly 5 and assembled in the final assembly workshop. Assembly points 4d, 4e, and 4f provide fixation for the air intake box 2 and volute 3 of the air conditioning unit, while assembly points 4a, 4b, and 4c provide fixation for the air distribution box 1. With this installation method, the center of gravity of the air conditioning unit is suspended and not located between the assembly points. The further back the center of gravity is, the greater the torque generated on the assembly points. This method is only suitable for sufficiently lightweight two-core structure air conditioning units and lacks versatility.

[0056] like Figure 2 and Figure 3As shown, the air conditioning unit layout in the final assembly is only suitable for low-cost commercial vehicles or small pure electric vehicles. These vehicles have lighter air conditioning units with a two-core structure. The core arrangement of distribution box 1 is as follows... Figure 2 As shown, the distribution box 1 integrates the evaporator core 6 and the heater core 7, or as... Figure 3 As shown, the distribution box 1 integrates the evaporator core 6 and the PTC core 8.

[0057] The air conditioning unit in the cabin is arranged as follows Figure 4 As shown, cabin assembly mounting points 9a, 9b, 9g, 9h, 9e, and 9f of the air conditioning unit are fixed to the instrument panel crossbeam assembly 10 and assembled at the cabin supplier. Cabin assembly mounting points 9c and 9d of the air conditioning unit are fixed to the front bulkhead assembly 5 and assembled in the final assembly workshop. Cabin assembly mounting points 9a, 9b, and 9c are related to the air conditioning unit's... The air intake box 2 and the volute 3 serve to fix the air conditioner box 1. The cabin assembly mounting points 9d, 9e, 9f, 9g, and 9h fix the air conditioner box distribution box 1. The air conditioner box with this installation method is located between the cabin assembly mounting points. However, the air conditioner box needs to be transferred to the supplier of the cabin assembly for assembly. The air conditioner box is prone to sinking during assembly. Special tooling is required for assembly. The overall vehicle cost is high. The assembly is difficult and the probability of error is high.

[0058] For hybrid commercial vehicles that use a PTC heater as the heat source for their air conditioning system, the air conditioning unit adopts a three-core structure, such as... Figure 5 As shown, the distribution box 1 integrates the evaporator core 6, the heater core 7, and the PTC core 8. The increased weight of the distribution box 1 section of the air conditioning unit and its rearward shift in center of gravity make traditional cabin assembly methods too costly. Traditional air conditioning unit assembly methods, with their rearward center of gravity, suffer from insufficient structural strength. Therefore, there is an urgent need for an air conditioning unit installation structure design that can ensure structural strength while reducing costs and assembly difficulty.

[0059] To solve the above technical problems, see Figure 6 , Figure 7 and Figure 8 This utility model provides an automotive air conditioning unit mounting structure, applicable to automotive air conditioning unit assembly processes. The automotive includes a front bulkhead assembly 5, a front floor assembly 11, and an integrated mounting bracket 12. The air conditioning unit includes a distribution box 1, an air intake box 2, and a volute 3. The integrated mounting bracket 12 is fixed to the surface of the front floor assembly 11, and the volute 3 is connected to both the distribution box 1 and the air intake box 2.

[0060] One side of the distribution box 1 is connected to the front bulkhead assembly 5, and the other side is connected to the integrated mounting bracket 12; the front bulkhead assembly 5 is connected to the air inlet box 2 and the volute 3 respectively.

[0061] Specifically, in this embodiment, the integrated mounting bracket 12 can be a stamped sheet metal part that integrates multiple mounting interfaces.

[0062] The aforementioned automotive air conditioning unit mounting structure connects the other side of the distribution box 1 to the integrated mounting bracket 12, thereby making the integrated mounting bracket 12 and the front floor assembly 11 serve as the rear support points of the automotive air conditioning unit. Compared to the final assembly method that only fixes the automotive air conditioning unit to the front bulkhead assembly 5 of the vehicle, this structure can support the automotive air conditioning unit through the front bulkhead assembly 5 on one side and the front floor assembly 11 on the other side, forming a "front and rear enclosed" support, distributing the weight of the automotive air conditioning unit, so that the center of gravity of the air conditioning unit is located between the front bulkhead assembly 5 and the front floor assembly 11, avoiding the rearward shift of the center of gravity, greatly reducing the supporting torque of the air conditioning unit, and ultimately improving the strength and stability of the automotive air conditioning unit mounting structure.

[0063] Furthermore, compared to the cabin assembly method that fixes the air conditioning unit to the instrument panel crossbeam assembly 10 and the front bulkhead assembly 5, the above-mentioned air conditioning unit mounting structure places the air conditioning unit on the integrated mounting bracket 12 of the front floor assembly 11 during assembly. This provides pre-support, forming a "sitting" installation that requires no manual assistance or the use of specialized tools (such as jacks). It is compatible with existing final assembly lines, has lower overall vehicle costs, is easier to assemble, and has a lower probability of error.

[0064] Preferably, the bottom of the dispensing box 1 is provided with a first support leg 13, the first support leg 13 extending outward relative to one side of the dispensing box 1, wherein:

[0065] The first support foot 13 is connected to the integrated mounting bracket 12.

[0066] In this preferred embodiment, the first support leg 13 extending outward from the distribution box 1 is connected to the integrated mounting bracket 12 to provide rear support for the distribution box 1 and share the weight of the air conditioning unit together with the front panel assembly 5. The extended design of the first support leg 13 can optimize the torque distribution of the support structure of the distribution box 1, thereby preventing the center of gravity of the air conditioning unit from shifting forward or backward, and improving the strength and stability of the air conditioning unit installation structure.

[0067] Preferably, the bottom of the dispensing box 1 is further provided with a second support leg 14, the second support leg 14 extending outward relative to one side of the dispensing box 1, and the second support leg 14 being symmetrically arranged side by side with the first support leg 13, wherein:

[0068] The second support foot 14 is connected to the integrated mounting bracket 12.

[0069] In this preferred embodiment, a second support leg 14 is added to the first support leg 13, which together connects to the integrated mounting bracket 12 to provide rear support for the distribution box 1 and share the weight of the air conditioning unit with the front panel assembly 5. The side-by-side symmetrical structure further optimizes the moment distribution of the support structure of the distribution box 1, so that the weight of the air conditioning unit on one side of the support leg is evenly distributed on the first support leg 13 and the second support leg 14, reducing the load on a single support leg and balancing the left and right moments on the side of the front floor assembly 11 of the distribution box 1, preventing the center of gravity of the air conditioning unit from shifting forward or backward, and further improving the strength and stability of the air conditioning unit installation structure.

[0070] Preferably, the first support leg 13 has a first support hole 15, and the second support leg 14 has a second support hole 16, wherein:

[0071] The first support foot 13 is tightly connected to the integrated mounting bracket 12 through the first support hole 15; the second support foot 14 is tightly connected to the integrated mounting bracket 12 through the second support hole 16.

[0072] This preferred embodiment, by opening the aforementioned support holes, enables the support feet to be tightly connected to the integrated mounting bracket 12 via threaded connection or by fastener through-locking, thereby improving the connection strength between the support feet and the integrated mounting bracket 12 and enhancing the strength and stability of the air conditioning unit installation structure.

[0073] Preferably, the thickness of the first support leg 13 and the second support leg 14 is 10mm, and the width of the first support leg 13 and the second support leg 14 is 50mm.

[0074] In this preferred embodiment, the thickness of the first support leg 13 and the second support leg 14 is 10mm, and the width of the first support leg 13 and the second support leg 14 is 50mm. While ensuring that the volume of the first support leg 13 and the second support leg 14 meets the space required for the electric gun assembly method, the volume of the load weight is increased and the torque of the support leg is reduced, thereby improving the strength and stability of the air conditioning unit installation structure.

[0075] Preferably, the distribution box 1 is provided with a first mounting foot 17, a second mounting foot 18 and a third mounting foot 19 on one side, wherein:

[0076] The first mounting foot 17 and the second mounting foot 18 are close to the top of the distribution box 1, and the first mounting foot 17 and the second mounting foot 18 are symmetrically arranged; the third mounting foot 19 is close to the bottom of the distribution box 1; the front panel assembly 5 is connected to the first mounting foot 17, the second mounting foot 18 and the third mounting foot 19 respectively.

[0077] In this preferred embodiment, a first mounting foot 17, a second mounting foot 18, and a third mounting foot 19 are respectively provided on the side of the distribution box 1 near the front bulkhead assembly 5 to connect with the front bulkhead assembly 5. The first mounting foot 17, the second mounting foot 18, and the third mounting foot 19 are distributed in a triangular layout at three locations on the side of the distribution box 1 near the front bulkhead assembly 5, which can distribute the weight load of the distribution box 1, avoid local stress concentration, thereby reducing the supporting moment of the distribution box 1. Together with the integrated mounting bracket 12 on the other side of the distribution box 1, they share the weight of the automotive air conditioning box, improving the strength and stability of the air conditioning box installation structure.

[0078] Preferably, the air inlet box 2 is symmetrically provided with a fourth mounting foot 20 and a fifth mounting foot 21 on both sides, wherein:

[0079] The fourth mounting foot 20 extends outward relative to one side of the air inlet box 2, and the fifth mounting foot 21 extends outward relative to the other side of the air inlet box 2; the front bulkhead assembly 5 is connected to the fourth mounting foot 20 and the fifth mounting foot 21 respectively.

[0080] Specifically, the mounting feet of the air inlet box 2 are used to fix the air inlet box 2, ensuring stable airflow at the inlet and preventing seal failure due to vibration. The symmetrical design of the fourth mounting foot 20 and the fifth mounting foot 21 can reduce assembly errors.

[0081] In this preferred embodiment, a fourth mounting foot 20 and a fifth mounting foot 21 are symmetrically arranged on both sides of the air intake box 2 near the front bulkhead assembly 5 to connect with the front bulkhead assembly 5. This can distribute the weight load of the air intake box 2 and balance the torque on both sides of the air intake box 2, thereby reducing the supporting torque of the air intake box 2. Together with the connection part of the front bulkhead assembly 5 at the distribution box 1 and the connection part of the integrated mounting bracket 12, the weight of the automotive air conditioning box is shared, thereby improving the strength and stability of the air conditioning box installation structure.

[0082] Preferably, the volute 3 is provided with a sixth mounting foot 22, wherein:

[0083] The sixth mounting foot 22 extends outward relative to the side of the volute 3; the front bulkhead assembly 5 is connected to the sixth mounting foot 22.

[0084] Specifically, the volute 3 mounting point is used to suppress the transmission of fan vibration to the vehicle body and reduce noise.

[0085] In this preferred embodiment, a sixth mounting foot 22 is provided at one end of the volute 3 near the front bulkhead assembly 5 and connected to the front bulkhead assembly 5. This connection part, together with the front bulkhead assembly 5 connection part at the distribution box 1, the integrated mounting bracket 12 connection part at the distribution box 1, and the front bulkhead assembly 5 connection part at the air intake box 2, shares the weight of the automotive air conditioning unit, thereby improving the strength and stability of the air conditioning unit installation structure.

[0086] This utility model embodiment also provides an automotive air conditioning unit, applicable to the automotive air conditioning unit installation structure as described in any of the first aspects of this utility model. The automotive air conditioning unit includes a distribution box 1, an air intake box 2, and a volute 3, wherein the volute 3 is connected to the distribution box 1 and the air intake box 2 respectively, wherein:

[0087] The bottom of the distribution box 1 is provided with a first support leg 13 and a second support leg 14. The first support leg 13 and the second support leg 14 extend outward relative to one side of the distribution box 1. The first support leg 13 and the second support leg 14 are symmetrically arranged side by side.

[0088] The other side of the distribution box 1 is provided with a first mounting foot 17, a second mounting foot 18 and a third mounting foot 19. The first mounting foot 17 and the second mounting foot 18 are close to the top of the distribution box 1 and are symmetrically arranged. The third mounting foot 19 is close to the bottom of the distribution box 1.

[0089] The air inlet box 2 is symmetrically provided with a fourth mounting foot 20 and a fifth mounting foot 21 on both sides. The fourth mounting foot 20 extends outward relative to one side of the air inlet box 2, and the fifth mounting foot 21 extends outward relative to the other side of the air inlet box 2.

[0090] The volute 3 is provided with a sixth mounting foot 22, which extends outward relative to one side of the volute 3.

[0091] The aforementioned automotive air conditioning unit can be connected to the front floor assembly 11 on one side of the vehicle via the first support leg 13 and the second support leg 14, and to the front bulkhead assembly 5 on the other side of the vehicle via the first mounting leg 17, the second mounting leg 18, the third mounting leg 19, the fourth mounting leg 20, the fifth mounting leg 21, and the sixth mounting leg 22. These eight connection points work together to distribute the weight of the air conditioning unit. The coordinated support and mounting leg components enhance the overall structural rigidity of the air conditioning unit.

[0092] Compared to the general assembly method that simply fixes the car air conditioning unit to the front bulkhead assembly 5 of the car, this car air conditioning unit can be supported by the front bulkhead assembly 5 on one side and the front floor assembly 11 on the other side, forming a "front and rear enclosed" support. This distributes the weight of the car air conditioning unit, so that the center of gravity of the air conditioning unit is located between the front bulkhead assembly 5 and the front floor assembly 11, avoiding the center of gravity from shifting backward. This greatly reduces the supporting torque of the air conditioning unit and ultimately improves the strength and stability of the car air conditioning unit installation structure.

[0093] Preferably, the first support foot 13 has a first support hole 15, and the second support foot 14 has a second support hole 16; the first mounting foot 17 has a first mounting hole, the second mounting foot 18 has a second mounting hole, the third mounting foot 19 has a third mounting hole, the fourth mounting foot 20 has a fourth mounting hole, the fifth mounting foot 21 has a fifth mounting hole, and the sixth mounting foot 22 has a sixth mounting hole.

[0094] In this preferred embodiment, through holes in the form of support holes or mounting holes are provided at each support foot and mounting foot, which enables the support foot to be tightly connected to the integrated mounting bracket 12 by means of threaded connection or by means of fastener through-locking, and the mounting foot to be tightly connected to the front panel assembly 5 by means of threaded connection or by means of fastener through-locking, thereby improving the connection strength between the support foot and the integrated mounting bracket 12, and improving the connection strength between the mounting foot and the front panel assembly 5, thereby improving the strength and stability of the air conditioning unit mounting structure.

[0095] The automotive air conditioning unit mounting structure and automotive air conditioning unit provided by this utility model have at least the following advantages compared with the prior art:

[0096] 1) The above-mentioned automotive air conditioning box installation structure connects the other side of the distribution box to the integrated mounting bracket, so that the integrated mounting bracket and the front floor assembly serve as the rear support point of the automotive air conditioning box. Compared with the final assembly method that only fixes the automotive air conditioning box to the front bulkhead assembly of the vehicle, this structure can support the automotive air conditioning box through the front bulkhead assembly on one side and the front floor assembly on the other side, forming a "front and rear enclosed" support, distributing the weight of the automotive air conditioning box, so that the center of gravity of the air conditioning box is located between the front bulkhead assembly and the front floor assembly, avoiding the rearward shift of the center of gravity, greatly reducing the support torque of the air conditioning box, and ultimately improving the strength and stability of the automotive air conditioning box installation structure.

[0097] 2) Furthermore, compared to the cabin assembly method that fixes the air conditioning unit to the dashboard crossbeam assembly and the front bulkhead assembly, the above-mentioned air conditioning unit mounting structure places the air conditioning unit on the integrated mounting bracket of the front floor assembly during assembly. This provides pre-support, forming a "sitting" installation that requires no manual assistance or the use of specialized tools (such as jacks). It is compatible with existing final assembly lines, has lower overall vehicle costs, is easier to assemble, and has a lower probability of error.

[0098] 3) The aforementioned automotive air conditioning unit has a sixth mounting foot 22 at one end of the volute 3 near the front bulkhead assembly 5, which connects to the front bulkhead assembly 5. This connection, together with the connection parts of the front bulkhead assembly 5 at the distribution box 1, the integrated mounting bracket 12 at the distribution box 1, and the front bulkhead assembly 5 at the air intake box 2, shares the weight of the automotive air conditioning unit, improving the strength and stability of the air conditioning unit's installation structure. The aforementioned automotive air conditioning unit can be connected to the front floor assembly 11 on one side of the vehicle via the first support foot 13 and the second support foot 14, and to the front bulkhead assembly 5 on the other side of the vehicle via the first mounting foot 17, the second mounting foot 18, the third mounting foot 19, the fourth mounting foot 20, the fifth mounting foot 21, and the sixth mounting foot 22. These eight connection points work together to share the weight of the air conditioning unit. The coordinated fixing and force-bearing by multiple support feet and mounting foot components enhances the overall structural rigidity of the air conditioning unit.
