Description

Technical Field

[0001] This utility model relates to the field of camera module fixing technology, specifically a camera module fixing structure. Background Technology

[0002] In today's digital age, various electronic devices are widely used, from everyday smartphones and tablets to professional security monitoring equipment and aerial drones. Cameras have become an indispensable component. As the core part for realizing the shooting function, the quality of the fixed structure of the camera module directly affects the shooting quality and equipment stability.

[0003] Traditional camera module fixing methods, such as simple clip fixing or glue bonding, cannot guarantee the stability of the camera module when faced with frequent vibrations and drops. Clips are prone to loosening and breaking, and ordinary glue bonding may fail due to heat or moisture, causing the camera module to shift or deviate, resulting in problems such as blurry images and inaccurate focus, which seriously affects the user experience. In addition, unstable fixed camera modules will generate friction due to shaking, which will seriously reduce the lifespan of the camera module. To address these issues, we have proposed a camera module fixing structure. Utility Model Content

[0043] Matching column 15: The matching column 15 is welded to the prism block 14 to form the fixed top component 5. Its shaft end fits into the matching groove 20 of the top kit 4 to enhance the connection stability.

[0044] Internal thread 16: Internal thread 16 passes through the prismatic block 14 and the mating post 15, and mates with the external thread of the lens module 13 to fix the axial position of the camera module 1.

[0045] Anti-sway side pad 2 17: Anti-sway side pad 2 17 is installed on the four inner walls of the top kit 4 and works in conjunction with anti-sway side pad 1 7 to prevent the camera module 1 from swaying laterally.

[0050] Working Principle: Install the camera module mounting structure correctly according to the diagram. When using this mounting structure, first place the camera module 1 inside the hollow rectangular frame structure composed of the mounting base 2 and the top kit 4. The mounting base 2 provides support and is fixedly connected to the camera device through the connecting hole 9, ensuring the entire mounting structure is firmly connected to the main body of the device. The back end of the camera module 1 is in contact with the shock absorber 3. During installation, the camera module 1 will exert pressure on the shock absorber 3, causing the C-shaped part 11 in the shock absorber 3 to be under pressure. In its retracted state, because the C-shaped parts 11 are arranged in two groups of two rows and five columns symmetrically, the rebound force they generate can exert force on the camera module 1 from multiple directions, thereby effectively ensuring the position of the camera module 1 is fixed and playing an overall anti-shake role. The top kit 4 has anti-shake side rubber pads 17 on its four inner walls and axial anti-shake rubber pads 18 on its bottom. These cooperate with the anti-shake side rubber pads 7 inside the fixed base 2. When the device is subjected to vibration or impact, these anti-shake rubber pads can buffer the external force on the camera module 1, further reducing its shaking and ensuring the camera's stability. The stability of the head module 1 is achieved by fixing the top component 5, which is composed of a prismatic block 14 and a mating post 15 welded together. Its internal mating thread 16 engages with the external thread of the lens module 13 of the camera module 1. During installation, the prismatic block 14 is rotated to secure the top component 5 to the lens module 13 using the threaded connection. The design of the prismatic block 14 not only facilitates handling and rotational disassembly, but also further fixes the axial position of the camera module 1 during tightening. The top kit 4 has a mating groove 20 corresponding to one end face of the top component 5. The mating of the shaft end of the column 15 enhances the stability of the connection between the fixed top component 5 and the top kit 4. At the same time, the mating holes 21 at the four corners of the end face of the top kit 4 away from the fixed top component 5 are bonded to the shaft end of the connecting rod 8 of the fixed base 2 with composite heat-resistant adhesive. This connection method is not only stable, but also effectively prevents connection failure due to overheating. The entire fixing structure, through the synergistic effect of each component, ensures the stability of the camera module 1 in the device from multiple aspects, so that it can maintain a good working state in various environments and ensure shooting quality.
