Description

Technical Field

[0001] This utility model relates to the field of optical lens technology, and in particular to a waterproof camera lens module based on a multi-layer composite structure. Background Technology

[0002] Nowadays, with the technological development of mobile terminal devices, camera modules have become an indispensable component of mobile terminals. Many users not only pursue the parameter performance of camera modules, but also have high requirements for their appearance and waterproof performance.

[0003] However, many current waterproof camera lens modules typically use flange rings to fix an external high-lens lens to the back panel of the mobile terminal, and seal it with sealant applied to the flange ring. The camera is installed from the inside, close to the inside of the high-lens lens. However, with the passage of time, if a leak occurs at the connection between the external high-lens lens and the back panel, or if the entire casing of the mobile device leaks, water vapor will quickly appear at the camera, preventing the camera from taking effective pictures. To address this, a waterproof camera lens module based on a multi-layer composite structure is provided to ensure that the camera can still capture clear images even in the event of minor leaks in the device. Utility Model Content

[0004] The purpose of this utility model is to provide a waterproof camera lens module based on a multi-layer composite structure, in order to solve the problem mentioned in the background art that, as the existing waterproof camera module assembly method increases with the use time, if leakage occurs at the connection between the external high lens and the back plate or the entire mobile device terminal casing, water mist will quickly appear at the camera, making it impossible for the camera to take effective pictures.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waterproof camera lens module based on a multi-layer composite structure, including a glass lens cover, a camera positioning waterproof component provided on the inner side of the glass lens cover, the camera positioning waterproof component including a light-shielding positioning plate disposed on the inner side of the glass lens cover, a camera glass cover being movably inserted into the light-shielding positioning plate, the camera glass cover abutting against the inner wall of the glass lens cover to ensure a seamless connection between the camera glass cover and the glass lens cover, and a sealing ring installed on the inner side wall of the camera glass cover to ensure a sealed assembly of the camera inserted between the camera glass cover.

[0006] Preferably, a fixing flange ring is installed on the outer wall of the glass lens cover, and the light-shielding positioning plate is installed on the inner side of the fixing flange ring.

[0007] Preferably, the outer side of the fixing flange ring is integrally formed with a housing assembly part, and the inner side of the fixing flange ring is integrally formed with a sealing part.

[0008] Preferably, the glass lens cover and the light-shielding positioning plate are both disposed in the mounting sealing part, and the outer edge of the glass lens cover is provided with an annular sealant so that the two sides of the glass lens cover are respectively sealed and assembled with the light-shielding positioning plate and the mounting sealing part.

[0009] Preferably, the light-shielding positioning plate has a first mounting hole and a second mounting hole, the camera glass cover is embedded in the first mounting hole, and the flash waterproof cover is fixedly embedded in the second mounting hole.

[0010] Preferably, the inner sides of the first assembly hole and the second assembly hole are provided with anti-detachment grooves, and a sealing ring is provided in the anti-detachment grooves.

[0011] Preferably, one side of the camera glass cover is integrally formed with an anti-detachment ring, the camera glass cover passes through the first mounting hole, and the anti-detachment ring abuts against the sealing ring in the first mounting hole.

[0012] Preferably, the flash waterproof cover passes through the second mounting hole, and one end of the flash waterproof cover is movably engaged in the second mounting hole, while a locking ring is fixedly adhered to the outer wall of the other end of the flash waterproof cover.

[0013] The technical effects and advantages of this utility model are as follows: By applying a ring-shaped sealant to the outer edge of the lens cover, and by mounting the camera glass cover and flash waterproof cover on a light-shielding positioning plate, the light-shielding positioning plate presses the camera glass cover and flash waterproof cover onto the lens cover, ensuring a seamless connection between them. Additionally, a sealing ring is placed inside the camera glass cover, achieving double waterproofing for the camera. During use, even if some moisture enters the inside of the lens cover, it will not appear at the camera tip, effectively preventing the camera from fogging up and becoming unusable.

A camera positioning waterproof component is provided on the inner side of the glass lens cover 2. The camera positioning waterproof component includes a light-shielding positioning plate 3 disposed on the inner side of the glass lens cover 2. A camera glass cover 4 is movably inserted into the light-shielding positioning plate 3. The camera glass cover 4 abuts against the inner wall of the glass lens cover 2 so that there is no gap between the camera glass cover 4 and the glass lens cover 2. A sealing ring 43 is installed on the inner side wall of the camera glass cover 4 so that the camera is inserted into the camera glass cover 4 for sealed assembly.

[0018] A fixing flange ring 1 is installed on the outer wall of the glass lens cover 2. A light-shielding positioning plate 3 is installed on the inner side of the fixing flange ring 1. A housing assembly part 12 is integrally formed on the outer side of the fixing flange ring 1, and a mounting sealing part 13 is integrally formed on the inner side of the fixing flange ring 1. Both the glass lens cover 2 and the light-shielding positioning plate 3 are set in the mounting sealing part 13, and an annular sealant 22 is provided on the outer edge of the glass lens cover 2 so that both sides of the glass lens cover 2 are sealed and assembled with the light-shielding positioning plate 3 and the mounting sealing part 13 respectively, thereby reducing the risk of leakage at the glass lens cover 2.
