In the technical scheme, the lens support is composed of a front support with a small diameter and a rear support with a large diameter which are coaxially arranged, the convex lens is embedded at the opening of the front support, and the PCB is connected with the port of the rear support.
In the above technical scheme, the side wall of the cover plate bracket is provided with a glue injection hole communicated with the closed cavity.
A cover plate component provided with a closed cavity into which transparent optical cement can be injected is additionally arranged at the front end of the lens component; the field angle of the miniature camera can be enlarged by selecting the transparent optical cement with low refractive index (lower than that of the convex lens).
As an improvement, a cover plate bracket with a glue injection hole (or called glue overflow hole) is arranged at the front end of the lens component and is fixed on the lens bracket.
The transparent cover plate is required to have good light transmittance and can be made of hard transparent materials or soft transparent materials.
The convex lens is required to have good light transmittance and can be made of hard plastics or glass.
The cover plate support and the lens support can also be combined into a whole.
The transparent optical cement is in a liquid state and is subjected to UV curing (ultraviolet curing) after injection.
Adopt the utility model discloses, when the angle of vision of camera is enlarged to needs, only need to seal the cavity evacuation earlier, then the pressurization pour into the transparent optical cement of low refractive index (lower than lens) and solidification can.
The utility model discloses miniature camera subassembly with large visual angle has following beneficial effect: by selecting transparent optical cement with low refractive index (lower than the convex lens), and utilizing the characteristic that the refraction angle of the optical cement in an optically thinner medium is larger than that of an optically denser medium, a larger field angle than that of a single micro camera is obtained, and by changing the glue injection pressure and with the help of a soft transparent cover plate, liquid optical cement is formed into convex lenses with different shapes and is solidified; the thicker the convex lens is, the smaller the focal length of the convex lens is, and the larger the field angle is, so that clearer image quality is obtained on the basis, and the purposes of large visual angle, clear captured image and low time delay are achieved.
