Problems solved by technology
[0003] However, if the user frequently operates the various software of the smartphone (such as shooting software or game software), it is easy for the circuit board and the photosensitive element to dissipate a lot of heat.
The dissipated heat energy will be conducted to the lens mount, causing the lens mount to expand when heated; in this way, the lens mount whose volume changes due to heating will affect the distance between the lens and the photosensitive element, causing the focal length of the lens to drift (that is, the phenomenon of thermal drift) ), resulting in deterioration of the captured image quality

The invention discloses an electronic device and a thermal drift preventing lens module. The thermal drift preventing lens module comprises a thermal drift preventing seat body, the thermal drift preventing seat body is arranged on a circuit board, and the thermal drift preventing seat body is made of a material preventing thermal expansion. The thermal drift preventing seat body comprises a shell, a first clamping and fixing groove, a first clamping and fixing piece, a lens tube, a lens and a photosensitive piece, wherein an accommodating space is formed between the shell and the circuit board; the first clamping and fixing groove is connected with the shell; the first clamping and fixing piece clamps and fixes the first clamping and fixing groove; the lens tube clamps and fixes the firstclamping and fixing piece; the lens is connected into the lens tube; and the photosensitive piece is connected with the circuit board and is located in the accommodating space and under the lens.
Description
technical field [0001] The invention relates to an anti-heat drift lens module, in particular to an anti-heat drift lens module which can prevent the focal length of the lens from drifting due to thermal deformation of the casing. Background technique [0002] Currently, the smart phones sold in the market all have lens modules, which can be used by users to take photos or videos at any time, which brings great convenience to users. A general lens module is arranged on a circuit board, and the lens module has a lens holder, a lens and a photosensitive element. The lens mount has a base body and a tube body, the bottom of the base body is connected to the circuit board, and the tube body is connected to the base body. The lens is arranged in the tube body. The photosensitive element is located inside the seat body and connected to the circuit board, and there is a certain focal distance between the photosensitive element and the lens. When taking pictures, the lens will tr...
