Composite cover plate, camera module and mobile terminal

Abstract

The invention discloses a composite cover plate. The composite cover plate comprises a cover plate body, a first light transmitting part and a second light transmitting part; a first through hole is formed in the cover plate body; the first light transmitting part is at least partially contained in the first through hole and is provided with a first light-entering surface which is a convex curved surface; light emitted by a flashlight enters the first light transmitting part from the first light-entering surface; the second light transmitting part is contained in the first through hole; the second light transmitting part is provided with a second light-exiting surface which is an inwards concave curved surface; the light emitted by the flashlight after penetrating the first light transmitting part penetrates the second light transmitting part and is emitted out from the second light-exiting surface; and the first light transmitting part, the second light transmitting part and the inner wall of the first through hole form a vacuum cavity. The invention also discloses a camera module and a mobile terminal. The utilization rate of the light of the flashlight is increased, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of imaging electronic equipment, in particular to a composite cover, a camera module and a mobile terminal. Background technique [0002] With the development of society, mobile terminals are becoming more and more important in people's lives. For example, mobile terminals such as mobile phones and tablet computers have become an indispensable part that people carry with them. The camera module is a functional module that enables the mobile terminal to realize functions such as taking pictures and taking pictures. Generally, the camera module includes a camera and a flashlight. The flashlight is used to provide stronger light in a weak light environment to obtain better photo effects. or camera effects. [0003] In the prior art, in order to beautify the camera and the flashlight, a transparent part protruding from the shell is used to cover the camera and the flashlight, so that the camera and the flashlig...
