Wherein, the base 110 is in the shape of a square, the positioning member 111 is in the shape of a ring, and the lens barrel 112 is in the shape of a cylinder. The diameter of the lens barrel 112 is slightly smaller than the diameter of the positioning member 111, so that the positioning member 111 After surrounding the lens barrel 112 , it forms a stepped structure with the lens barrel 112 . The lens 113 is accommodated in the lens barrel 112, and the image sensor 114 is built in the base 110. The lens 113 and the image sensor 114 are existing imaging elements, which will not be described in detail here.

In this embodiment, the base 110 , the positioning member 111 and the lens barrel 112 are an integrated structure. In another embodiment, the positioning member 111 can also be a separate ring-shaped part, sleeved on the lens barrel 112 and in contact with the upper surface 1100 of the base 110, and attached to the lens barrel by sticking 112 and the base 110 are fixed together.

The end 1120 of the lens barrel 112 of the camera module 11 protruding from the positioning member 111 is sprayed with a pressure-sensitive adhesive 1121 . The end 1120 of the lens barrel 112 is circular, the protective lens 12 is circular, and its diameter is the same as the outer diameter of the end 1120. The end 1120 is used to protect the camera module 11 to prevent dust or other sundries from contaminating the camera module 11 . In this embodiment, the protective mirror 12 is made of transparent plastic or glass.

In the present invention, the protective mirror 12 and the camera module 11 can be pre-fixed together, and fixed in the receiving groove 210 through the positioning member 111 during assembly, so that the protective mirror 12 and the camera module 11 can be protected during and after assembly. The mirror 12 can effectively prevent dust or other sundries from contaminating the camera module 11, so as to ensure the imaging quality of the camera.

Please refer to FIG. 2 , FIG. 4 and FIG. 5 , the receiving portion 21 is a boss protruding inward from the inner surface of the housing 20 , and the receiving groove 210 is formed in the boss and perpendicular to the inside of the housing 20 . A cylindrical receiving space on the surface has a diameter approximately the same as the outer diameter of the positioning member 111, so that when the camera assembly 10 is accommodated in the receiving portion 21, the protective mirror 12, the lens barrel 112 and the positioning member 111 are just completely accommodated in the In the receiving groove 210 of the receiving part 21, a part of the upper surface 1100 of the base 110 also abuts against the surface 211 of the receiving part 21 where the receiving groove 210 is opened, and the upper surface 1100 of the base 110 is sprayed with pressure-sensitive Glue 1101 , the upper surface 1100 is in contact with the surface 211 of the receiving portion 21 , so that the camera assembly 10 is bonded and fixed on the receiving portion 21 through the pressure-sensitive adhesive 1101 , so that the camera assembly 10 is fixed on the casing 20 .
