Description

Technical Field

[0001] This utility model belongs to the field of automotive air conditioning component design technology, and relates to an assembly structure for an automotive air conditioning filter cover. Background Technology

[0002] Automotive air conditioning, as a crucial component of automobiles, mainly comes in offset, center-mounted, and split types. It primarily consists of an air intake unit, a blower unit, and a distribution unit. The air intake unit is responsible for drawing in air from inside or outside the vehicle, which is then distributed into the vehicle by the blower unit and distribution unit, creating a safe and comfortable driving environment for passengers, reducing fatigue, and improving driving safety. The air intake unit comprises an air inlet, an air intake housing, internal and external circulation dampers, a filter, and a filter cover. The internal and external circulation dampers are installed inside the air intake housing, the filter is installed inside the air intake housing, below the internal and external circulation dampers, and the filter cover is assembled with the housing. Air drawn in from inside or outside the vehicle by the air intake unit is filtered to improve air quality. The filtered fresh air then enters the vehicle, providing a safe and comfortable driving environment for passengers, reducing fatigue, and improving driving safety.

[0003] However, the traditional automotive air conditioning filter cover assembly structure has the following problems: like Figures 1-7 As shown, in terms of assembly structure and clearance, the traditional filter cover assembly structure (see...) Figure 1 The filter consists of an internal circulation damper (1), a left inlet housing (2), a right inlet housing (3), a filter (4), and a filter cover (5). Because traditional filter covers and housings are made of plastic, there is a risk of deformation during production and manufacturing. If the product is deformed before assembly, issues such as… Figure 2 The assembly gap shown is a whistling and hissing sound that can occur when using the car's air conditioning in a quiet driving environment. This not only affects the performance of the air conditioning unit but also reduces the safety and comfort of the occupants.

[0004] In addition, regarding auxiliary assembly structures, traditional filter covers (see...) Figure 3 There are no auxiliary assembly structures on the filter. This design makes it very easy for the aforementioned whistling and hissing sounds to occur when the filter cover is assembled with the housing due to deformation.

[0005] Secondly, traditional filter covers also have certain flaws in their snap-fit ​​design. For example... Figure 4 The traditional automotive air conditioning filter cover assembly structure shown has a snap-fit ​​design where the filter cover rotates around one end, the air intake box has mounting holes for the cover, and clips are provided on the cover for assembly. Figure 5 As can be seen from the enlarged schematic diagram, the upper and lower edges of the filter cover are equipped with clip-on structures. Figure 6 The demonstration showcased a snap-fit ​​mechanism; however, this mechanism requires pre-positioning before pushing, making the assembly process complex. Furthermore, additional pressing and other actions are needed to ensure proper alignment. Moreover, disassembling the filter cover snap-fit ​​mechanism is difficult when replacing the filter. Additionally, the flat, load-bearing surface of the filter cover snap-fit ​​is not easily stressed, causing significant inconvenience during operation. Figure 7 As shown, this is another traditional filter cover with a snap-fit ​​structure housing hole design. The filter cover rotates around one end, and the clips on the cover engage with the housing holes. It also has the same problem as the previous filter cover.

[0006] In summary, the two traditional filter cover structures mentioned above either suffer from gaps due to deformation, affecting aesthetics and causing whistling, or employ a snap-fit ​​structure, which presents technical problems such as difficulties in assembly and disassembly, and urgently need improvement. Utility Model Content

[0007] In view of this, the purpose of this utility model is to provide an assembly structure for automotive air conditioning filter covers, so as to solve the technical problems of whistling, difficult installation and difficult disassembly of traditional automotive air conditioning filter cover assembly structures.

[0008] To achieve the above objectives, this utility model provides the following technical solution: An automotive air conditioning filter cover assembly structure includes an internal circulation damper, a left air intake housing, a right air intake housing, a filter, and a filter cover. The left and right air intake housings are assembled to form an air intake housing. The internal circulation damper is mounted inside the air intake housing. The filter is installed inside the air intake housing and located below the internal circulation damper. The filter cover is assembled and connected to the air intake housing. An assembly buckle is provided on one side of the left air intake housing, and a fastening rib is provided on the right air intake housing. One end of the filter cover is inserted into the assembly buckle, rotates around the assembly buckle, and engages with the fastening rib. Crucially, it also includes an auxiliary assembly structure. The auxiliary assembly structure includes a strip-shaped auxiliary structure arranged on the filter cover and a figure-eight buckle arranged on the air intake housing. The strip-shaped auxiliary structure is assembled with the figure-eight buckle to eliminate the whistling sound generated by the assembly gap between the filter cover and the air intake housing.

[0009] Furthermore, the opening size of the figure-eight buckle is smaller than the size of the strip-shaped auxiliary structure to compensate for the gap caused by the deformation of the air inlet housing.

[0010] Furthermore, the figure-eight buckle is arranged on the right side of the air inlet box near the left side of the air inlet box, so as to be located in the middle of the air inlet box.

[0011] Furthermore, the strip-shaped auxiliary structure is integrally formed with the filter cover.

[0012] Furthermore, the figure-eight buckle is integrally formed with the right shell of the air inlet box.

[0013] Furthermore, the strip-shaped auxiliary structure is a square, circular, polygonal, or irregular strip-shaped structure.

[0014] Furthermore, the figure-eight buckle is arranged on the left housing of the air inlet box and is integrally formed with the left housing of the air inlet box.

[0015] The beneficial effects of this utility model are as follows: This technical solution addresses the problems of squealing, difficulty in installation, and difficulty in disassembly inherent in traditional automotive air conditioning filter cover assembly structures, proposing an optimized assembly structure. Its core lies in: arranging auxiliary assembly structures (including strip-shaped auxiliary structures on the filter cover and figure-eight clips on the air intake housing) on ​​the air intake housing and the filter cover; inserting the assembly clips into one end of the filter cover, rotating them to engage with the rib, while simultaneously securing the strip-shaped auxiliary structures and the figure-eight clips together to achieve a seamless connection.

[0016] First, this invention effectively eliminates whistling and hissing sounds caused by assembly gaps. By designing the opening of the figure-eight buckle to be smaller than the size of the strip-shaped auxiliary structure, it compensates for gaps caused by shell deformation, ensures airtightness, avoids abnormal airflow noise, and improves the quietness of the air conditioning system.

[0017] Secondly, the assembly process is simple and efficient, requiring no additional actions; a simple rotation and snap-fit ​​is all that's needed to get it in place, solving the problems of difficult assembly and disassembly in traditional structures, making it suitable for production and maintenance scenarios. Thirdly, the structure is simple and reliable; the one-piece molding enhances connection strength, and after multiple verifications, it is stable, durable, and not easily loosened. Finally, the cost is low, requiring only the addition of auxiliary components without increasing complex processes, while simultaneously improving driving comfort and safety and reducing noise interference with driving attention. This utility model optimizes traditional pain points, providing a practical and economical technical improvement.
