Problems solved by technology

In the traditional design, this part of the light blocking is made of flat foam, and the light is blocked by squeezing the foam. However, due to the material characteristics of the foam itself, its elasticity will age with time, resulting in The risk of light leakage or dust ingress. In addition, if the size design is unreasonable and the compression is too large, it will cause greater stress on the printed circuit board, which may affect the service life of the imaging module.

Abstract

The invention provides a monitoring product imaging module device comprising a lens and an image sensor, wherein the monitoring product imaging module device further comprises a lens bracket structure, a push plate structure and a back plate structure; the lens bracket structure comprises a supporting plate, and a plurality of guide rods are arranged below the supporting plate; the push plate structure comprises a circuit board and a push plate main body, the back plate structure comprises a back plate main body and a screw, and a top end of the screw penetrates through the back plate main body and leans against a bottom surface of the push plate main body; the guide rods connect the circuit board, the push plate main body and the back plate main body together, a compression spring is arranged on the guide rod between the supporting plate and the circuit board, and a light shielding structure is further arranged between the supporting plate and the circuit board. The monitoring product imaging module device has high compatibility on different lenses and different image sensors, and relatively high market adaptability; in addition, the lens is fixed more quickly due to a self-centering fixing mode, and the reject ratio of the product is greatly reduced; and the wavy light shielding structure is more difficult to leak light or enter dust.

Description

technical field [0001] The invention relates to the field of safety monitoring, in particular to an imaging module device for monitoring products. Background technique [0002] In the design of surveillance products, the imaging module is the most important design link, including the installation and fixation of the lens, the design of the light blocking structure, and the compatibility design of the lens and image sensor. Some current imaging module designs always need to make compatibility compromises, because different image sensors have different imaging heights and surface glass thicknesses (glass has a refractive index, and glass with different thicknesses will result in different imaging heights), And most of the M12 lenses and Φ14 lenses on the market currently have different back focus. For research and development, to be compatible with these, a compromise must be made, such as designing a compatible structure, which is very unfavorable to the various needs of user...
