Description

Technical Field

[0001] This invention belongs to the field of axial fan technology, specifically relating to a wind shield with an integrated air filter cavity structure, used for heat dissipation and gas filtration in automotive systems. Background Technology

[0002] China's automotive market is booming and has grown into the world's largest automobile consumer market. With the ongoing price war in the domestic automotive market, automakers are constantly employing various cost-reduction and efficiency-enhancing measures to lower their Bill of Materials (BOM) costs and maintain price competitiveness. Take cooling fans as an example: traditionally, fans have been used for forced air cooling of automotive radiator units. However, with the increasing demand for structural integration, fans are now required to perform a wider range of additional functions. Summary of the Invention

[0003] To address the problems existing in the prior art, this invention provides a radiator fan shroud with an integrated air filter cavity. It adopts a method of integrating the automotive air filter cavity and the plastic housing of the radiator cooling fan into one piece, which simplifies the assembly structure of the engine intake unit in the vehicle, optimizes the intake air duct, and realizes the integration and flattening of the intake unit.

[0004] The technical solution of the present invention is: a radiator fan shroud with an integrated air filter cavity, comprising an engine air filter cavity integrally injection molded onto a plastic fan shroud as a structural component of the shroud body.

[0005] Furthermore, four right-angle continuous tension ribs are provided at the connection between the engine air filter cavity and the plastic windshield shroud, and the ribs of the right-angle continuous tension ribs are designed to be non-equally divided.

[0006] Furthermore, the outer contour deformation suppression ribs are arranged in a 5 vertical and 4 horizontal pattern on the left side of the outer surface of the engine air filter cavity shell, and in a 7 vertical and 9 horizontal pattern on the front area. The deformation suppression ribs are partially connected to 4 right-angle connecting ribs.

[0007] Furthermore, the plastic wind shield has an independently integrated mounting bracket on its air ring.

[0008] Furthermore, the holes on the mounting base are pre-drilled during the injection molding process using rivet screws, and are shaped to match the rivet holes.

[0009] Furthermore, the mounting bracket is a water pump motor mounting bracket.

[0010] Furthermore, an assembly fastening support is provided at each of the four corners of the plastic wind shield's air ring.

[0011] The beneficial effects of this invention are: it provides a radiator fan shroud with an integrated air filter cavity.

[0012] 1. By using injection molding, multiple traditionally separate components (air filter chamber) are integrated into the radiator fan assembly cover, simplifying the number of parts and assembly process, while also bringing about cost reduction and weight reduction at the vehicle level.

[0013] 2. The design features an independent, integrated water pump mounting hole, reducing the safety hazards associated with traditional plastic-coated inserts during the injection molding process.

[0014] 3. The unique design of the air filter cavity with reinforcing ribs on the outer contour suppresses surface deformation and increases structural strength. Attached Figure Description

[0018] The present invention will now be further described with reference to the accompanying drawings.

[0019] like Figure 1 , 2 As shown, a wind shield integrating an air filter cavity structure is provided. This integrated structure consists of 1 (plastic wind shield ring), 2 (engine air filter cavity), 3 (assembly fastening feet), and 4 (mounting base).

[0020] (1) Integrated air filter chamber

[0021] An air shroud for a radiator cooling fan is disclosed. This invention integrates an air filter cavity structure into a plastic shroud body. This cavity is integrally injection molded as a structural component of the air shroud body during the injection molding process. Compared to traditional designs, this part is a separate component, requiring additional molding molds and processing / assembly steps.

[0022] (2) Riveted water pump mounting feet

[0023] Depending on the vehicle's overall layout requirements, the wind shield can be integrated with mounting brackets for water pump motors or other similar components (serial number 4). These brackets typically use plastic-coated inserts, meaning the inserts are manually placed into the mold cavity during injection molding, a process often fraught with safety hazards. This patent utilizes rivet screws, requiring only pre-drilling holes to match the rivet holes during injection molding, followed by machining by a specialist on a dedicated tooling table after injection molding.

[0024] (3) Design of integrated high-strength ribs in the cavity

[0025] In the area where the air filter cavity and the cover are joined (serial number 5), four right-angle continuous tension ribs are visible. These ribs are non-equally divided. On the left side of the outer surface of the air filter cavity shell, there are five vertical and four horizontal outer contour deformation suppression ribs. On the front area, there are seven vertical and nine horizontal outer contour deformation suppression ribs. These deformation suppression ribs are connected to the four right-angle continuous tension ribs, which makes the overall structural strength and outer contour shape suppression ability of this case outstanding.

[0026] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
