[0002] In the production and manufacturing of camera modules, many dust spots are often generated in the process flow. Even if the ordinary base vent hole design can eliminate 90% of the dust spots, there are still dust spots running down from the vent holes, resulting in IC stains (POD) or IR stains (POG), and the vent hole design of the ordinary base is not conducive to draining water vapor. Therefore, fog will be generated in a high temperature environment, causing the camera module lens to be blurred. Therefore, a waterproof and fog-proof camera module base is designed, which can effectively prevent dust from entering the base plate and facilitate air outlet. Utility Model Content
[0003] The utility model aims to overcome the shortcomings of the prior art and provide a camera module base that is waterproof and fogproof.
[0004] The purpose of this utility model is achieved through the following technical solutions:

[0006] In one embodiment, the air escape hole is arranged at a position in the center of the bottom plate close to the top, and the inner diameter of the air escape hole is 0.4 mm and the outer diameter of the air escape hole is 0.2 mm.
[0007] In one of the embodiments, a holder shape center is disposed in the center of the bottom plate, the front face of the holder shape center is square, and a light hole center is disposed in the center of the holder shape center.
[0008] In one of the embodiments, gates are provided on the left and right sides of the top of the camera module base near the center, and the front of the gates is a trapezoid that is wide at the top and narrow at the bottom.
[0009] In one of the embodiments, a plurality of guide post connection holes are provided on the front side of the base plate body, the front side of the guide post connection holes is circular in shape, and the guide post connection holes are centered on the center of the holder shape and are designed with equal distances around them.
[0010] In one embodiment, the distance between the center of the holder shape and the bottom plate is in the range of 1.0483 mm ± 0.04 mm, and the four corners of the bottom plate and the center of the holder shape are rounded.
[0011] In one embodiment, the interior of the air escape hole is a spiral structure, so its diameter gradually decreases from the outside to the inside, and the inner hole of the air escape hole is located on the surface of the sensor.
[0012] In one of the embodiments, the outer hole and the inner hole of the air escape hole are both circular in shape, and a sealing plug that can be taken out is provided on the air escape hole.
[0013] In one of the embodiments, part of the inner cavity of the bottom plate is matte treated.
[0014] Compared with the prior art, the utility model has at least the following advantages:
[0015] The waterproof and fog-proof camera module base of the utility model can further reduce the possibility of dust points entering the inner cavity of the bottom plate through the air escape hole during the production process by designing the air escape hole with a small outer hole and a large inner hole. At the same time, the inner cavity of the air escape hole is designed in a spiral shape, so it is not only conducive to the discharge of water vapor. The outer hole is small and dust is not easy to enter, and the inner and outer parts are threaded. Even if dust enters, it will fall on the edge of the thread and is not easy to fall on the sensor surface, thereby preventing it from affecting the imaging of the camera module.
