Their camera modules usually have basic shooting functions to meet daily communication and recording needs. The user interface is simple, and the resolution and image processing capabilities of the camera module are usually not too high to ensure ease of use and long battery life.

[0003] A traditional mobile phone camera module typically consists of a lens, an image sensor, a driving circuit, and other additional components. The lens is responsible for capturing light, the image sensor converts light into electronic signals, and the driving circuit controls the operation of the image sensor to ensure image acquisition and processing. These components are connected by certain circuits and mechanical connections to realize the basic functions of a camera.

[0004] Traditional mobile phone camera modules are susceptible to water corrosion, primarily because the internal structure of the camera typically contains tiny gaps or interfaces that allow moisture to enter the module. Water ingress affects lens clarity, image sensor operation, and can even cause short circuits or corrosion. Furthermore, camera modules generally have weak sealing and waterproofing capabilities, especially without specially designed waterproofing measures; water intrusion can lead to performance degradation or malfunction. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a waterproof mobile phone camera module, which aims to improve the problem that traditional mobile phone camera modules are easily corroded by water, affecting the clarity of the lens and the operation of the image sensor.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a waterproof mobile phone camera module, including a fixed outer frame, a waterproof outer shell fixedly connected inside the fixed outer frame, a camera module fixedly connected inside the waterproof outer shell, and a sealing component provided inside the waterproof outer shell;

[0007] The sealing assembly includes a rubber sealing ring, which is fixedly connected inside the waterproof housing. A secondary sealing ring is fixedly connected inside the waterproof housing. An infrared filter is fixedly connected inside the waterproof housing. The outer wall of the waterproof housing is provided with a polyurethane hydrophobic coating. A protective component is provided on the side wall of the fixed outer frame.

[0008] Furthermore, the protective assembly includes a glass cover and connecting shafts, the glass cover being rotatably connected to the side wall of the fixed outer frame, and a plurality of connecting shafts being fixedly connected to the upper surface of the glass cover.

[0009] Furthermore, each of the connecting shaft sidewalls is fixedly connected to a limiting shaft, and the bottom of the fixed outer frame is fixedly connected to multiple side platforms.

[0010] Furthermore, each of the side platforms is fixedly connected to multiple side plates, and an internal fixed shaft is fixedly connected inside the multiple side plates.

[0011] Furthermore, the outer wall of the inner fixed shaft is rotatably connected to a first limiting plate, and the outer wall of the inner fixed shaft is rotatably connected to a second limiting plate.

[0012] Furthermore, the second limiting plate has an inner groove, and the first limiting plate is slidably connected inside the inner groove.

[0013] Furthermore, the second limiting plate and one side wall of the limiting plate are both fixedly connected to a connecting plate, and each connecting plate is provided with a spring at its bottom.

[0014] Furthermore, one end of each spring is fixedly connected to the lower surface of the connecting plate, and the other end of the spring is fixedly connected to the upper surface of the side platform.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the rubber sealing ring and the secondary sealing ring inside the waterproof shell work together to form a double sealing protection, preventing moisture and dust from seeping in through gaps and ensuring the stable operation of the camera module. The outer wall of the waterproof shell is coated with a polyurethane hydrophobic coating to further enhance the waterproof performance, ensuring that water droplets roll on the surface and do not remain on the module surface. The camera module can work normally in humid or harsh environments, avoiding malfunctions caused by water erosion.

[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-2 This utility model provides an embodiment of a waterproof mobile phone camera module, including a fixed outer frame 1, a waterproof outer shell 2 fixedly connected inside the fixed outer frame 1, and a camera module 5 fixedly connected inside the waterproof outer shell 2. The waterproof outer shell 2 ensures the protection of the camera module 5 from the external environment, reducing the impact of external moisture, dust, etc. on the camera. A sealing component is provided inside the waterproof outer shell 2 to further improve the protective effect; the sealing component includes a rubber sealing ring 3, which is fixedly connected inside the waterproof outer shell 2 to prevent moisture and dust from seeping in through gaps, ensuring the long-term stable operation of the camera module 5. 2. An internal fixed connection includes a secondary sealing ring 4, which further enhances waterproof sealing and provides a second layer of protection, ensuring more reliable protection performance. An infrared filter 6 is fixedly connected inside the waterproof housing 2. The infrared filter 6 can effectively filter out unnecessary infrared rays, ensuring that image quality is not interfered with and improving the clarity and accuracy of captured images. The outer wall of the waterproof housing 2 is provided with a polyurethane hydrophobic coating 7. The polyurethane coating can effectively repel water, causing water droplets to roll on the surface of the housing and making them difficult to adhere, thereby improving the waterproof effect and preventing water from affecting the module. Protective components are provided on the side wall of the fixed outer frame 1.

[0025] Specifically, firstly, the fixed outer frame 1 provides basic structural support for the entire camera module, ensuring the stability of each component. The waterproof housing 2 tightly encloses the camera module 5, effectively isolating the external environment from the internal components and reducing interference from factors such as moisture and dust. The rubber sealing ring 3 and the secondary sealing ring 4 inside the waterproof housing 2 work together to form a double seal, effectively preventing moisture and dust from seeping into the interior through any possible gaps, ensuring the stable operation of the camera module 5 in various environments. The infrared filter 6 is placed inside the waterproof housing 2, which can effectively filter out unnecessary infrared rays, ensuring the accuracy of the captured image. The image is clearer and more accurate, thus avoiding image quality degradation caused by light interference. The outer wall of the waterproof housing 2 is coated with a polyurethane hydrophobic coating 7, which further enhances the waterproof performance. This causes water droplets to roll on the surface of the module and not stay on the surface, thereby reducing the potential damage of water to the camera module 5. The protective components set on the side wall of the fixed outer frame 1 provide additional physical protection for the module, which can effectively prevent external impacts from causing direct damage to the module, further improving the durability and stability of the module. It can work normally even in humid, damp or other harsh environments, effectively avoiding malfunctions or damage caused by water intrusion.

[0026] Reference Figure 3 The protective assembly includes a glass cover plate 8 and connecting shafts 9. The glass cover plate 8 is rotatably connected to the side wall of the fixed outer frame 1. Multiple connecting shafts 9 are fixedly connected to the upper surface of the glass cover plate 8. Each connecting shaft 9 has a limiting shaft 10 fixedly connected to its side wall. Multiple side platforms 11 are fixedly connected to the bottom of the fixed outer frame 1. Multiple side plates 12 are fixedly connected to the side wall of each side platform 11. An inner fixing shaft 13 is fixedly connected inside the multiple side plates 12. A limiting plate 14 is rotatably connected to the outer wall of the inner fixing shaft 13. A second limiting plate 15 is rotatably connected to the outer wall of the inner fixing shaft 13. An inner groove 16 is opened inside the second limiting plate 15. The first limiting plate 14 is slidably connected inside the inner groove 16. Connecting plates 17 are fixedly connected to the side walls of the second limiting plate 15 and the first limiting plate 14. A spring 18 is provided at the bottom of each connecting plate 17. One end of each spring 18 is fixedly connected to the lower surface of the connecting plate 17, and the other end of the spring 18 is fixedly connected to the upper surface of the side platform 11.

[0027] Specifically, when the glass cover plate 8 is needed to further protect the camera module 5, the glass cover plate 8 is first rotated so that the multiple connecting shafts 9 are tightly engaged with the side wall of the side platform 11. At this time, the limiting plate 14 and the limiting plate 2 15 start to function. The limiting plate 14 slides in the inner groove 16 inside the limiting plate 2 15. As it rotates, the included angle between the limiting plate 14 and the limiting plate 2 15 gradually widens, allowing the connecting shafts 9 to smoothly enter the interior. After the connecting shafts 9 enter, the spring 18 applies an elastic force to the connecting plate 17, pushing the limiting plate 14 and the limiting plate 2 15 to reset, and finally limiting the connecting shafts 9 and the limiting shafts 10. This ensures that the glass cover plate 8 can be opened and closed conveniently. The glass cover plate 8 can effectively prevent external dust, stains or other substances from contaminating the lens, keeping the lens clean, and thus ensuring that the shooting effect is not affected.

[0028] Working Principle: First, the fixed outer frame 1 provides structural support for the module, while the waterproof outer shell 2 encloses the camera module 5, minimizing the impact of the external environment on the internal components. The rubber sealing ring 3 and secondary sealing ring 4 inside the waterproof outer shell 2 work together to form a double seal, preventing moisture and dust from seeping in through gaps and ensuring stable operation of the camera module 5. The infrared filter 6, located inside the waterproof outer shell 2, effectively filters unwanted infrared rays, ensuring the clarity and accuracy of the captured images. The outer wall of the waterproof outer shell 2 is coated with a polyurethane hydrophobic coating 7, further enhancing waterproof performance and ensuring that water droplets roll off the surface and do not remain on the module surface. The protective components on the side walls of the fixed outer frame 1 provide additional physical protection, preventing damage to the module from external impacts. The camera module can operate normally in humid or harsh environments, avoiding malfunctions caused by water corrosion. When the glass cover plate 8 is needed to further protect the camera module 5, the glass cover plate 8 is rotated so that multiple connecting shafts 9 are fastened to the side wall of the side platform 11. At this time, the first limiting plate 14 and the second limiting plate 15 are pulled, so that the first limiting plate 14 slides in the inner groove 16 inside the second limiting plate 15, further widening the included angle between the two so that the connecting shafts 9 can enter the interior. Then, the spring 18 applies elastic force to the connecting plate 17, so that the first limiting plate 14 and the second limiting plate 15 are reset, limiting the connecting shafts 9 and the limiting shafts 10, realizing the convenient opening and closing of the glass cover plate 8, preventing external dust, stains or other substances from contaminating the lens, thereby keeping the lens clean and ensuring the shooting effect.

[0029] 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.
