[0033] 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.

[0034] Reference Figures 1-3 This utility model provides an embodiment of a camera module's three-proof sealing and potting structure, including a housing 1, which is the main supporting component of the structure and provides an installation base for other components. A bearing ring 2 is fixedly connected to the outer wall of the housing 1. The bearing ring 2 is used to support and position the components to be installed later, and plays a connecting and supporting role. The front side of the bearing ring 2 contacts the rear side of the cover 3. An installation ring 13 is fixedly connected to the front side of the bearing ring 2. The cover 3 contacts the bearing ring 2, which can seal and protect the internal structure. The installation ring 13 is used to connect with the cover 3 by threads to realize the fixed installation of the cover 3. An installation groove 8 is provided on the inner wall of the front side of the bearing ring 2. The installation groove 8 provides installation space for the sealing strip 7 and ensures the stability of the position of the sealing strip 7.

[0035] Reference Figures 4-6A sealing strip 7 is installed in the mounting groove 8. The sealing strip 7 enhances the sealing performance of the structure and prevents the ingress of water and other substances from the outside. The sealing strip 7 is annular, allowing it to contact relevant components from all directions, thus improving the sealing effect. The front side of the sealing strip 7 is concave, which helps to better cooperate with components such as the pressure ring 6, enhancing the tightness of the seal. The front side of the mounting groove 8 contacts the pressure ring 6, which is used to press the sealing strip 7, ensuring that the sealing strip 7 makes full contact with other components and guarantees the sealing effect. The front side of the pressure ring 6 is flush with the front side of the outer shell 1, and the pressure ring 6 is positioned between the mounting ring 13 and the outer shell 1. This positioning allows the pressure ring 6 to be accurately positioned during installation, forming a seal with the mounting ring 13 and the outer shell 1. With a good fit, a fixing ring 9 is fixedly connected to the rear side of the pressure ring 6. The fixing ring 9 can further enhance the connection stability between the pressure ring 6 and the bearing ring 2 and prevent the pressure ring 6 from loosening. The rear side of the fixing ring 9 contacts the front side of the bearing ring 2. A positioning block 10 is fixedly connected to the rear side of the pressure ring 6. The positioning block 10 is used to position the pressure ring 6 to ensure that the pressure ring 6 is accurately positioned during installation. The positioning blocks 10 are evenly distributed on the rear edge of the pressure ring 6. A lens 4 is provided on the front side of the pressure ring 6. The lens 4 is a key component of the camera module used for imaging. A cover 3 is threadedly connected to the mounting ring 13. Through the threaded connection, the cover 3 can be firmly installed on the mounting ring 13 to seal the internal structure. The front diameter of the cover 3 is slightly larger than the diameter of the lens 4.

[0036] Reference Figure 7 A glue-filling hole 11 is provided on the inner wall of the right side of the cover 3. The glue-filling hole 11 is used to inject sealant to further enhance the sealing performance of the structure and achieve the three-proof (waterproof, dustproof, and corrosion-proof) function. A sealing post 12 is snapped onto the inner wall of the glue-filling hole 11. After the glue is filled, the sealing post 12 is used to seal the glue-filling hole 11 to prevent the sealant from flowing out and the entry of external substances. An anti-sliding block 5 is fixedly connected to the right side of the sealing post 12. The anti-sliding block 5 is set to facilitate the stable gripping of the camera module. There are four anti-sliding blocks 5, which are evenly distributed on the side wall of the cover 3.

[0037] Working principle: During assembly, the sealing strip 7 is first installed in the mounting groove 8 on the inner wall of the front side of the bearing ring 2, and the mounting groove 8 is used to position and fix the sealing strip 7. Then, the pressure ring 6 is placed between the mounting ring 13 and the outer shell 1, so that the fixing ring 9 on the rear side of the pressure ring 6 contacts the front side of the bearing ring 2. At the same time, the evenly distributed positioning blocks 10 ensure that the pressure ring 6 is accurately positioned. The pressure ring 6 will form a clamping force on the sealing strip 7 in the mounting groove 8. Since the front side of the sealing strip 7 is concave, it can better fit with the pressure ring 6 under pressure, thus initially achieving a seal in the structure.

[0038] Next, the lens 4 is placed in front of the pressure ring 6, and the sealing cover 3 is connected to the mounting ring 13 by thread, so that the sealing cover 3 is firmly installed and forms a closed protection for the internal components. The design of the front side of the sealing cover 3 being slightly larger than the diameter of the lens 4 can protect the lens 4.

[0039] Afterwards, sealant is injected through the injection hole 11 on the inner wall of the right side of the cap 3. The sealant fills the gaps between the components, further enhancing the overall sealing performance and achieving waterproof, dustproof, and corrosion-resistant functions. After the sealant is injected, the sealing post 12 is snapped into the injection hole 11 to seal the injection hole 11 and prevent the sealant from flowing out and external substances from entering. The anti-slip block 5 on the right side of the sealing post 12 facilitates stable gripping and disassembly during operation.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
