Abstract

The present application discloses a lens barrel, a lens assembly, a camera module and an electronic device. The lens barrel includes: a side wall, the side wall is formed in a ring shape, and the side wall defines a accommodating cavity; a top wall, the top wall is connected to one end of the side wall , the top wall has a light-transmitting hole communicating with the accommodating cavity, the top wall has a top surface, and a connecting surface connecting the top surface and the inner surface of the light-transmitting hole, the connecting surface is provided with a plurality of first protrusions, each first The projections are all arranged around the optical axis, and any two adjacent first projections are arranged at intervals, and the longitudinal section of each first projection is formed into a triangle. According to the lens barrel of the present application, the light rays directed toward the first reflection plane and the second reflection plane along the optical axis direction of the light-transmitting hole can be reflected out at least twice, and the energy of the reflected light rays can be weakened, thereby achieving a black effect of . In addition, the longitudinal section of the first protrusion is a triangle, which can prevent the light irradiated on the top surface of the first protrusion from being directly reflected, thereby ensuring the blackening effect.

Description

technical field [0001] The present application relates to the technical field of electronic devices, and in particular, to a lens barrel, a lens assembly, a camera module and an electronic device. Background technique [0002] In the related art, the surface of the lens of the electronic device is made black by coating, so as to achieve a super black effect. However, the coating needs to use coating equipment, which will increase the production cost. SUMMARY OF THE INVENTION [0003] The present application proposes a lens barrel, which can achieve a blackening effect. [0004] The present application also proposes a lens assembly including the above-mentioned lens barrel. [0005] The present application also provides a camera module, the camera assembly includes the above-mentioned lens assembly. [0006] The present application also provides an electronic device, the electronic device includes the above-mentioned camera module. [0007] A lens barrel according to an...
