Abstract

The invention relates to a lens which comprises a lens barrel, a first lens unit and a second lens unit are arranged in the lens barrel, a driving part is arranged on the first lens unit, and during zooming or focusing, the driving part shrinks or expands under the action of temperature so as to drive the first lens unit to move in the direction of an optical axis; and the second lens unit comprises a liquid lens, the liquid lens is filled with a transparent solution, and the transparent solution is heated to expand during zooming or focusing or is cooled to contract during zooming or focusingso as to regulate and control the focal power of the liquid lens. According to the lens, the use of a motor rotor and an induction coil can be avoided, and the thickness of the lens module is effectively reduced. The invention also relates to an image capturing device and electronic equipment.

Description

technical field

[0001] The invention relates to the technical field of optical imaging, in particular to a lens, an imaging device and electronic equipment. Background technique

[0002] At present, the zooming of the lens is through the application of the voice coil motor, under the current control, the magnetic induction effect of the coil is used to move the motor mover up and down, and then the far and near focus adjustment of the lens is realized by mounting the lens on the mover.

[0003] However, the inventor found in the process of realizing the traditional technology that the thickness of the lens module determines the thickness of the mobile phone, but because the lens zoom needs a motor, and the internal structure of the motor needs to be wound with a coil to achieve electromagnetic induction, it is easy to cause the lens module to be damaged. Increased thickness. Contents of the invention

[0004] Based on this, it is necessary to provide an improved lens for ...
