Embodiment Construction

[0031] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. A preferred embodiment of the invention is shown in the drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the present invention will be thorough and complete.

[0032] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is said to be "connected" to another element, it may be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. The terms "vertical," "horizontal...

Abstract

The invention relates to a lock cover, a lens, a camera module and an electronic device. The lock cover is used for being installed on the object side of a lens cone, a light passing opening is formedin the lock cover, light from the object side enters a lens cone through a light passing opening, the lock cover comprises an extinction surface close to the object side and adjacent to the light passing opening. An extinction surface surrounds the light passing opening, at least one extinction groove is formed in the extinction surface, and the extinction grooves are used for reducing the intensity of the light entering the extinction grooves. When the extinction groove is formed in the area close to the light passing opening, most of light entering the extinction groove is reflected for multiple times in the extinction groove, so that the intensity of the light finally emitted from the extinction groove is reduced, and the effect of effectively reducing stray light can be achieved. Theextinction groove is formed in the lock cover, so that after the lock cover and the lens cone are assembled, stray light can be reduced to a great extent before entering the optical system, and the problem that the imaging quality is reduced due to the fact that the stray light enters the optical system can be effectively solved.

Description

technical field [0001] The invention relates to the field of photography and imaging, in particular to a lock cover, a lens, a camera module and an electronic device. Background technique [0002] For a common lock cover, the lock cover is sleeved on the object side of the lens barrel to seal the lens in the lens barrel. The lock cover is often made of copper, aluminum and other materials, and the surface is blackened by blackening treatment or oxidation treatment for matting. This process is used to prevent the phenomenon of stray light caused by the reflection caused by the high reflectivity of the material surface. However, although this type of traditional matting process can reduce the reflectivity of the surface, it is still difficult to effectively reduce the stray light entering the optical system. Contents of the invention [0003] Based on this, it is necessary to provide a lock cover, a lens, a camera module and an electronic device for how to effectively elimi...
