[0002] The camera module is a core component used in portable camera equipment, mainly composed of image sensors, lenses, voice coil motors, flexible circuit boards, connectors and other parts. It is mainly used in mobile phones, laptops, tablets, smart homes, smart wearables, vehicles, VR / AR and security surveillance.

[0003] The lens in the mobile phone camera module needs to be exposed on the outside of the mobile phone, so it will inevitably be corroded by water. The waterproof performance of the lens in the existing mobile phone camera module is not very ideal, which may cause moisture to enter the inside of the mobile phone, causing damage to the entire mobile phone circuit and causing unnecessary trouble to the user.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] See also Figures 1 to 4In the utility model, a waterproof mobile phone camera module comprises a mounting seat 1 and a lens module 2 mounted therein. A mounting groove 3 is provided on the top of the mounting seat 1, and an expansion groove 4 is provided on the inner bottom wall of the mounting groove 3. A lens glass 5 is mounted on the top of the mounting seat 1, and a mounting ring 6 is fixedly connected to the bottom of the lens glass 5. The bottom end of the mounting ring 6 passes through the mounting groove 3 and is located inside the expansion groove 4. Two water-swellable rubber rings 7 are connected to the inner wall of the mounting groove 3, and the two water-swellable rubber rings 7 are respectively located on the inner and outer sides of the mounting ring 6. The top of the water-swellable rubber ring 7 is coated with a color-changing coating 8. A protective seat 9 is slidably mounted on the outside of the mounting seat 1, and a protective plate 10 is rotatably connected to the top of the protective seat 9, and the protective plate 10 is located on the top of the lens glass 5.

[0024] The two sides of the protection seat 9 are fixedly connected with a snap-fit ​​strip 11, the outer ring of the protection seat 9 is provided with a mounting frame 12, the inner wall of the mounting frame 12 is provided with a snap-fit ​​groove 13, and the snap-fit ​​strip 11 is located inside the snap-fit ​​groove 13;

[0025] The color-changing coating 8 is made of a hydrogel indicator material.

[0026] The lens module 2 is installed inside the mounting seat 1, and the mounting seat 1 is integrated on the mobile phone. The installer sets the protective seat 9 on the outside of the mounting seat 1 so that the protective plate 10 is on the top of the lens glass 5, and then installs the mounting frame 12 to connect to the mobile phone. The snap-fit ​​strip 11 is located inside the snap-fit ​​groove 13 to limit the protective seat 9, and the mounting ring 6 at the bottom of the lens glass 5 is connected to the inside of the mounting groove 3, and the mounting groove 3 is connected with two water-swellable rubber rings 7. In the subsequent use process, the protective seat 9 and the protective plate 10 can protect the mounting seat 1 and the lens glass 5 to prevent bumps, and the protective plate 10 can also prevent water from contacting the lens glass 5. When the lens module 2 needs to be used for filming, the user pushes the protective plate 10 to rotate, so that the metal plate 17 and the magnet 16 are separated to expose the mounting seat 1 and then filming can be carried out. If the seal of the lens glass 5 fails during use, water flows into the inside of the mounting groove 3 through the gap. At this time, the installer The water flow inside the mounting groove 3 needs to contact the water-swellable rubber ring 7 on the outside and then flow to the inside of the expansion groove 4, and then spread through the expansion groove 4 to contact the water-swellable rubber ring 7 on the inside and then enter the mounting seat 1 to corrode the lens module 2. When the water flow initially contacts the water-swellable rubber ring 7 on the outside, it will expand to fill the gap to prevent the water flow from continuing to enter. The hydrogel indicator on its top is hygroscopic in a dry state. Once it contacts moisture, the hydrogel will expand and change, and present different colors due to different degrees of moisture absorption, such as blue, pink, etc. This color change allows people to quickly understand the state of the coating through naked eye observation, and reminds of possible moisture intrusion. The user can observe the coating color to determine whether the lens glass 5 is sealed, so as to facilitate timely maintenance to avoid affecting the internal lens module 2, and the water ingress situation can be determined according to the coating changes on both the inside and outside to perform maintenance accordingly.

[0027] In the utility model, by arranging two groups of water-swellable rubber rings 7 at the connection position between the lens glass 5 and the mounting seat 1, it is possible to effectively prevent moisture and dust from invading the interior of the lens module 2, thereby improving the waterproof and dustproof performance of the equipment and extending the service life of the camera module. The color-changing coating 8 on the top thereof can quickly change color after the glass seal fails, reminding the user to promptly inspect and replace parts, thereby avoiding damage to the internal lens module 2. The user can intuitively see the color changes of the inner and outer coatings and determine whether there is a seal failure without disassembling the entire camera module, making maintenance more convenient and quick. At the same time, by arranging a protective seat 9 and a protective plate 10 on the outside of the mounting seat 1, the waterproof and anti-fall effects are further improved, and the water flow is blocked before the water flow contacts the lens glass 5.

[0028] See also Figure 1 , 34, wherein: a finger groove 14 is provided on the top of the protective plate 10, and evenly distributed anti-slip grooves are provided on the inner wall of the finger groove 14.

[0029] In the present invention, when the user needs to rotate the protection plate 10, the finger groove 14 can provide a fulcrum for the user, and the anti-skid pattern can prevent the user from slipping.

[0030] See also Figure 1 , 3 4, wherein: a sealing rubber ring 15 is fixedly connected to the top of the protective seat 9, and the top of the sealing rubber ring 15 contacts the bottom of the protective plate 10.

[0031] In the present invention, the provision of the sealing rubber ring 15 can further improve the sealing between the protective plate 10 and the protective seat 9, improve the protection effect on the lens glass 5, and can also increase the friction to prevent the protective plate 10 from rotating.

[0032] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
