Abstract

The invention relates to the technical field of optical lenses and provides a lens barrel, a lens module and an assembling method thereof. A first barrel wall provided with a light through hole, and asecond barrel wall which is bent and extends from the first barrel wall are included. The first barrel wall comprises an outer wall surface close to an object side, and the outer wall surface is provided with a groove used for being filled with a buffer gas. The lens barrel further comprises an air plug piece arranged in the groove, the buffer gas is sealed in the groove through the air plug piece, and the air plug piece can move relative to the lens barrel along an optical axis. According to the technical scheme, when the lens module is assembled, impact on the lens barrel can be absorbed bycompressing the buffer gas so that a deformation problem of the lens barrel in an assembling process is relieved, a mutual impact force between the lens barrel and the lens is further weakened, deformation of a lens assembly is relieved, technical problems that the lens is easily subjected to plastic deformation due to excessive impact and even possibly cracks when the lens is seriously impactedare solved, and meanwhile an assembling yield can be increased.

Description

【Technical field】 [0001] The invention relates to the technical field of optical lenses, in particular to a lens barrel, a lens module and an assembly method thereof. 【Background technique】 [0002] With the continuous development of science and technology, electronic devices are constantly developing towards intelligence. In addition to digital cameras, portable electronic devices such as tablet computers and mobile phones are also equipped with lens modules with camera and video functions to meet the needs of users to take pictures at any time. The lens module of the related art includes a lens barrel with a light hole and a lens assembly accommodated in the lens barrel. When the lens assembly is assembled and fixed in the lens barrel, an assembly impact force will be generated, and the assembly impact force is completely absorbed by the lens assembly. ; Due to the low strength of the lens assembly, the lens assembly is prone to plastic deformation due to excessive assembl...
