Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning technology, specifically to a connection structure for an evaporator and a blower. Background Technology

[0002] The automotive air conditioning system mainly uses the HVAC assembly as the core module. The HVAC assembly integrates a heater, evaporator, blower and damper mechanism, and is responsible for heating, cooling, dehumidifying and ventilating the air in the vehicle.

[0003] By integrating the evaporator assembly and blower assembly together during production, a unified air conditioning assembly is formed. While this high level of integration facilitates installation, it presents the following significant limitations in actual vehicle integration: Due to significant differences in chassis structure, cabin layout, wiring harness routing, and housing installation space among different vehicle models, integrated HVAC assemblies are difficult to use across different platforms and usually require a dedicated structure designed for each vehicle model.

[0004] This not only results in poor product versatility and low platformization, but also requires the separate establishment of corresponding molds, production lines and supply chain systems during production, increasing development costs and limiting the standardization and large-scale manufacturing capabilities of parts.

[0005] Furthermore, the integrated structure makes it difficult to repair or replace a single functional component if it fails, requiring the entire HVAC assembly to be disassembled, which increases maintenance costs.

[0006] Therefore, in order to solve the above problems, it is necessary to provide a connection structure for the evaporator and the blower. Summary of the Invention

[0007] This utility model addresses the shortcomings of existing technologies by proposing a connection structure for an evaporator and a blower. The specific technical solution is as follows: A connection structure for an evaporator and a blower, characterized by comprising: An evaporator housing, wherein an air outlet is provided on one side of the evaporator housing; A blower housing, wherein an air inlet is provided on one side of the blower housing corresponding to the air outlet; A connecting pipe, the two ends of which are respectively connected to the air outlet and the air inlet, is used to facilitate airflow when the evaporator housing and the blower housing are arranged separately; The evaporator housing and the blower housing are provided with a matching connection structure to fix the two together so that the air outlet and the air inlet can be directly connected.

[0008] To better realize this utility model, it can be further made as follows: First connecting seat, a plurality of first connecting seats are disposed on the connecting side of the evaporator housing; The number of second connectors is the same as the number of first connectors; The second connecting seat is disposed on the connecting side of the blower housing; The first connecting seat and the second connecting seat correspond one-to-one and are connected by a connecting piece to fix the evaporator housing to the blower housing.

[0009] Furthermore: the first connecting seat is a nut seat; The second connecting seat is used to pass through a locking bolt that is threaded with the nut seat to fix the evaporator housing to the blower housing.

[0010] Furthermore: the edge of the air inlet is provided with a first flange arranged circumferentially thereon; The edge of the air outlet is provided with a second flange arranged circumferentially thereon; The two ends of the connecting tube are respectively fitted onto the first flange and the second flange.

[0011] Furthermore, the outer diameters of both the first flange and the second flange are larger than the inner diameter of the connecting pipe to form an interference seal.

[0012] Furthermore, the connecting pipe is provided with a heat insulation layer.

[0013] Furthermore, both ends of the connecting tube are fixedly connected to the first flange and the second flange respectively by screws.

[0014] Furthermore: the evaporator housing is provided with a first limiting block, which is located near the air outlet; A second limiting block is provided on the connecting surface of the blower housing, and the second limiting block is located near the air inlet; The two ends of the connecting pipe are respectively provided with limiting grooves that cooperate with the first limiting block and the second limiting block.

[0015] Furthermore, both the air inlet and the air outlet are circular structures. The beneficial effects of this utility model are as follows: This utility model is compatible with both split and integrated layout methods, suitable for the installation needs of various vehicle models, and facilitates platform-based design and modular configuration. Specifically, it includes the following points: First, when the vehicle's overall layout space is compact, the connecting pipes are omitted, and the evaporator housing and blower housing adopt an integrated structure. The utility model uses a first connecting seat on the connecting side of the evaporator housing and a second connecting seat on the connecting surface of the blower housing. The first and second connecting seats are connected by locking bolts, thus fixing the evaporator housing and blower housing together. This ensures a tight fit between the air outlet and the air inlet. This integrated structure is suitable for vehicles with existing compact air conditioning assemblies.

[0016] Secondly, in the split-type layout structure, connecting pipes are used as flexible conductive components to adapt to changes in the housing spacing of different vehicle models. The two ends of the connecting pipes form an interference fit with the flanges on the air outlet and air inlet, effectively improving sealing performance and shock resistance.

[0017] Third, the connecting pipe has limiting grooves at both ends, which cooperate with the corresponding limiting blocks on the housing for positioning. This can help to align the screw holes during assembly, improving the accuracy and efficiency of assembly. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

They are used only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] This embodiment describes a connection structure for an evaporator and a blower, such as... Figures 1 to 6 As shown, it includes an evaporator housing 1, a blower housing 2, a connecting pipe 3, and a connecting structure.

[0022] The evaporator housing 1 has a circular air outlet 4 on its air outlet side, which is used to guide the cooled airflow to the subsequent airflow channel.

[0023] The blower housing 2 has a circular air inlet 5 on its air inlet side, which is used to receive the airflow from the air outlet 4.

[0024] The air outlet 4 and the air inlet 5 are arranged opposite each other and have the same diameter. Both of them adopt a circular structure to achieve uniform transition and smooth flow of air.

[0025] When the evaporator housing 1 and the blower housing 2 are installed in a separate arrangement, the airflow between the evaporator housing 1 and the blower housing 2 is achieved through the connecting pipe 3.

[0026] The connecting pipe 3 is a hollow tubular structure used to establish an airflow channel when the evaporator housing 1 and the blower housing 2 are not directly connected.

[0027] The two ends of the connecting pipe 3 are connected to the air outlet 4 and the air inlet 5 respectively, ensuring that cold air is introduced from the air outlet 4 to the air inlet 5 through the connecting pipe 3.

[0028] The edge of the air inlet 5 has a first flange 6 formed along its circumference, and the edge of the air outlet 4 has a second flange 7 formed along its circumference. The first flange 6 and the second flange 7 have the same structure, both adopting an outwardly convex annular step structure, which is used to insert into the inner cavity at both ends of the connecting pipe 3.

[0029] Specifically, the first flange 6 and the second flange 7 are respectively inserted into the corresponding ends of the connecting pipe 3, and the outer diameters of the first flange 6 and the second flange 7 are slightly larger than the inner diameter of the connecting pipe 3, thereby forming an interference fit during insertion. This interference seal connection method can not only effectively prevent gas leakage and ensure the airtightness of the air passage, but also enhance the overall seismic stability of the structure.

[0030] Meanwhile, the outside of the connecting pipe 3 is provided with a heat insulation layer to reduce the heat exchange between hot and cold gases.

[0031] To enhance structural stability, the two ends of the connecting pipe 3 are threadedly fixed to the first flange 6 and the second flange 7 respectively by screws 8.

[0032] When the evaporator housing 1 and the blower housing 2 are installed as a single unit: the evaporator housing 1 and the blower housing 2 are provided with a mutually cooperating connection structure to achieve a stable connection between the two when the evaporator housing 1 and the blower housing 2 are installed as a single unit.

[0033] Specifically, the connection structure includes multiple first connecting seats 9 and multiple second connecting seats 10. Preferably, three first connecting seats 9 and three second connecting seats 10 are provided. The three first connecting seats 9 are evenly distributed on the connecting side of the evaporator housing 1, and the three second connecting seats 10 are evenly distributed on the connecting side of the blower housing 2. The first connecting seats 9 and the second connecting seats 10 are in one-to-one correspondence.

[0034] The first connecting seat 9 is a nut seat, and the second connecting seat 10 is used to pass through the locking bolt. The locking bolt passes through the second connecting seat 10 in sequence along the axial direction and is threaded to the corresponding nut seat, thereby realizing a firm locking connection between the evaporator housing 1 and the blower housing 2.

[0035] The split connection structure allows airflow through the connecting pipe 3, providing excellent flexible installation capabilities.

[0036] The connecting pipe 3 can be selected in different lengths according to different layout conditions of the whole vehicle to meet the space constraints of various models.

[0037] When the length of the connecting pipe 3 is zero, it is an integral connection where the evaporator housing 1 and the blower housing 2 are directly connected.

[0038] The above structure can flexibly adjust the relative positions of the evaporator housing 1 and the blower housing 2, thereby adapting to the interior layout requirements of different vehicle models, and has good modularity and adaptability advantages.

[0039] This split connection method eliminates the need to customize an integrated air conditioning assembly for each vehicle model, effectively reducing product development cycle and manufacturing costs.

[0040] At the same time, this structure facilitates the universal platform design of air conditioning systems, making it easier for later standardized assembly, mass production, and maintenance operations. The aforementioned integrated connection structure, as a special assembly form of the split connection structure, is suitable for application scenarios where the overall vehicle layout space is relatively compact and components require a high degree of integration.

[0041] Users can flexibly choose the appropriate connection method based on the overall vehicle structure or the layout of the air conditioning system.

[0042] When using an integrated connection structure, in order to ensure accurate insertion of the connecting pipe 3 during the assembly process, limiting grooves are provided at both ends of the connecting pipe 3.

[0043] The two limiting grooves respectively cooperate with the first limiting block 11 on the evaporator housing 1 and the second limiting block 12 on the blower housing 2, thereby limiting the radial direction of the connecting pipe 3.

[0044] When the limiting grooves are engaged with the first limiting block 11 and the second limiting block 12 respectively, the threaded holes at both ends of the connecting pipe 3 are precisely aligned with the threaded holes on the first flange 6 and the second flange 7, so that the screw 8 can be quickly inserted and locked, improving assembly efficiency.

[0045] The principle of this utility model is as follows: In practical use, depending on the different spatial layouts inside the vehicle compartment, the evaporator housing 1 and the blower housing 2 can be arranged separately or installed as an integrated unit.

[0046] When a split-type arrangement is adopted, airflow between the two is achieved by setting a connecting pipe 3. The length of the connecting pipe 3 can be flexibly adjusted according to the installation space of a specific vehicle model, thereby achieving flexible adaptation of the positions of the evaporator housing 1 and the blower housing 2.

[0047] The two ends of the connecting pipe 3 are respectively fitted with the second flange 7 provided on the edge of the air outlet 4 of the evaporator housing 1 and the first flange 6 provided on the edge of the air inlet 5 of the blower housing 2. The outer diameter of the first flange 6 and the second flange 7 are slightly larger than the inner diameter of the connecting pipe 3, and an interference seal is formed after insertion.

[0048] When the overall vehicle layout space is limited and the distance between the evaporator housing 1 and the blower housing 2 is small, the evaporator housing 1 and the blower housing 2 can be directly integrated into a single mounting structure. In this case, the two are directly connected through a mutually cooperating connection structure, eliminating the intermediate connecting pipe 3, and allowing the air outlet 4 and the air inlet 5 to directly connect, forming a compact integrated installation layout.

[0049] Therefore, this utility model, through the combination design of split layout and fixed connection structure, significantly enhances the adaptability and modularity of the air conditioning system assembly in different vehicle models.
