[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] Example

[0027] Combine Figures 1 to 5 This embodiment provides a filter element suitable for use in an automotive filter device, comprising a filter element 1 and an outer frame 2 that at least partially surrounds the filter element 1. The outer frame 2 includes a top plate 21 and a bottom plate 22 extending perpendicularly to the insertion direction, and two side plates 23 connected to the top plate 21 and the bottom plate 22. The length of the top plate 21 is greater than the length of the bottom plate 22, so that the side plates 23 and the bottom plate 22 form a plug-in component that is convenient for insertion into the automotive filter device. A mounting member 3 extends outward from one of the side plates 23 to form an inlet slope. The mounting member 3 is provided with a base 31 that is perpendicularly connected to the external fastener 51.

[0028] In the above-mentioned filter element, the outer frame 2 at least partially surrounds the filter element 1, and the outer frame 2 includes a top plate 21, a bottom plate 22 and two side plates 23 extending perpendicular to the insertion direction. The length of the top plate 21 is greater than the length of the bottom plate 22, so that the bottom plate 22 and the two side plates 23 form a plug-in component suitable for insertion, which helps to smoothly install the filter element in the automobile filter device, effectively improves the convenience of installation and disassembly, and at the same time enhances the fixing effect of the filter element in the automobile filter device, providing users with simpler and safer air filtration.

[0029] In particular, one of the side panels 23 is provided with an outward-extending mounting member 3, which includes an inlet bevel to facilitate the rapid alignment and insertion of the filter element, thereby reducing the reliance on multiple operating protrusions in the prior art, simplifying the installation process, and allowing users to complete loading and unloading with only a small operating force. In addition, a base 31 is provided on the mounting member 3 for vertically docking with the external fastener 51, achieving a reliable fixing effect. After installation, the filter element is not easy to loosen, ensuring stable filtering performance during use.

[0030] In this embodiment, the base 31 is wedge-shaped, with a pinhole 311 defined at its top that mates with the fastener 51. On one hand, the wedge-shaped base 31 facilitates insertion and secures the filter element. The pinhole 311 precisely mates with the fastener 51, ensuring the filter element's stability within the device and preventing loosening during vehicle vibration and daily use. On the other hand, the pinhole 311 mates with the fastener 51, allowing users to secure the filter element with a simple docking motion during installation. This reduces the number of steps and the required assembly effort, improving installation efficiency and making it particularly suitable for frequent filter element 1 replacement scenarios.

[0031] In addition, the wedge-shaped base 31 provides a good self-locking effect, ensuring that the position of the filter element is not easily displaced after installation. At the same time, the wedge-shaped structure also increases the connection strength between the base 31 and the frame, thereby improving the overall structural durability.

[0032] In this embodiment, the mounting member 3 further includes wedge-shaped ribs 32 spaced apart and opposed to each other on either side of the base 31. The outer edges of the wedge-shaped ribs 32 and the outer edges of the base 31 cooperate to form a substantially inclined guide surface. The wedge-shaped ribs 32 and the outer edges of the base 31 cooperate to form the inclined guide surface, allowing for quick guidance of the filter element during insertion into the filter device, reducing jamming and misalignment during installation and facilitating smoother operation.

[0033] Furthermore, the base 31 and wedge-shaped rib 32 are integrally formed on the outer surface of the side panel 23, and their height is lower than that of the top panel 21, so that the mounting member 3 is sunken relative to the top panel 21. Thus, the mounting member 3 is sunken relative to the top panel 21, so that the base 31 and wedge-shaped rib 32 do not exceed the height of the top panel 21, thereby preventing the mounting member 3 from interfering with surrounding structures during insertion, and enhancing the adaptability of the filter element to different vehicle models and spaces.

[0034] Furthermore, since the mounting member 3 is in a sunken position, its structure is less susceptible to external impact or wear during use, thereby improving the durability of the filter element and reducing the possibility of structural damage. The base 31 and wedge-shaped ribs 32 are integrally formed with the side panels 23, forming a more secure connection. This not only reduces the number of assembly parts but also enhances the overall strength of the filter element, ensuring its stability within the filter device.

[0035] like Figure 2 As shown, in this embodiment, one side plate 23 is vertically arranged between the top plate 21 and the bottom plate 22, wherein the other side plate 23 is formed by a vertical section 231 and a sloped section 232, and the mounting member 3 is formed on the vertical section 231. Among them, the vertically arranged side plate 23 plays a role in preliminary positioning and makes the overall structure more regular. The other side plate 23 adopts a combination connection of the vertical section 231 and the sloped section 232, so that the overall shape of the filter element is more conducive to insertion. The sloped section 232 provides a guiding effect, making it easier for the filter element to slide into the filter device, simplifying the installation process. In addition, the mounting member 3 is located on the vertical section 231, which provides a stable installation base, which is convenient for docking with the fastener 51, thereby ensuring that the position of the filter element in the device is firm and not easy to shift.

[0036] Preferably, the vertical section 231 and the inclined section 232 are of equal length. This ensures more even force distribution between the two sections during insertion and securing, reducing deformation or damage caused by unbalanced force and improving the overall strength and stability of the filter element. The same lengths of the vertical section 231 and the inclined section 232 create a more symmetrical filter element structure, simplifying identification of the installation direction, and improving assembly convenience and fault tolerance, making it suitable for quick installation requirements.

[0037] It is worth mentioning that the top plate 21 and the bottom plate 22 are configured to be elastically deformable at least during the insertion process. Obviously, the elastic deformation ability of the top plate 21 and the bottom plate 22 allows the filter element to adapt to slight changes in the installation space during insertion, effectively avoiding jamming and making installation smoother.

[0038] Combine Figures 3 to 5This embodiment further provides an automotive filter device comprising a housing 4, a top cover 5, and the aforementioned filter element. The top cover 5 and the housing 4 are joined to form a receiving space for the filter element, and the receiving space can be sealed by the top cover 5. The plug-in component is configured for rapid insertion into the housing 4, and the top cover 5 is provided with at least one fastener 51 that engages with the base 31.

[0039] The above are only preferred implementations of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention fall within the protection scope of the present invention.
