Embodiment 1

[0027] The ultra-thin voice coil motor of this embodiment includes a housing, a bracket 2, a lens mount 3, a focusing coil 4, an anti-shake coil 6, a magnet 5, a circuit board 7, a first elastic member and a second elastic member 9, and the bracket 2 , the lens holder 3, the focusing coil 4, the anti-shake coil 6, the magnet 5, the circuit board 7, the first elastic member and the second elastic member 9 are all arranged in the casing.

[0028] The casing includes an upper casing 11 and a lower cover 12, and the upper casing 11 and the lower cover 12 are connected to form a mounting bracket 2, a lens mount 3, a focusing coil 4, an anti-shake coil 6, a magnet 5, a first elastic member and a second The accommodating cavity of the elastic member 9.

[0029] The lens mount 3 is fixedly connected to the bracket 2 through the first elastic member, and the lens mount 3 can move relative to the bracket 2 . In this embodiment, the first elastic member includes an upper spring 81 and a...

Embodiment 2

[0042] The camera head of this embodiment has the ultra-thin voice coil motor described in the first embodiment. When the ultra-thin voice coil motor is used in the camera, the height of the camera can be reduced, so that the camera can be used in an ultra-thin mobile phone, the camera has a wide application range, and can meet the development needs of mobile phones.

Abstract

The invention relates to the technical field of camera driving devices, in particular to an ultra-thin voice coil motor and a camera. The ultra-thin voice coil motor comprises a shell, a bracket, a lens holder, a first rotor, a second rotor and a stator, and the bracket can be arranged in the shell movably relative to the shell; the lens holder can be connected with the bracket movably relative tothe bracket and is used for installing a lens; the first rotor is fixedly arranged on the lens holder, and the first rotor movably drives the lens holder to move; the second rotor is arranged on thebracket corresponding to the first rotor and is used for driving the first rotor to move, and the second rotor movably drives the bracket to move; the stator is fixedly arranged in the shell corresponding to the second rotor and is used for driving the second rotor to move; and the second rotor is located between the first rotor and the stator. The ultra-thin voice coil motor in the invention hasthe advantages of being more compact in structure and low in height.

Description

technical field [0001] The invention relates to the technical field of camera driving devices, in particular to an ultra-thin voice coil motor and a camera. Background technique [0002] With the development of science and technology, and consumers' demand for mobile phones to be portable, the thickness of mobile phones is getting thinner and thinner. As an important part of the mobile phone, the mobile phone camera is getting lower and lower in height. In the current prior art, such as the Chinese patent document CN104460180A, a voice coil motor for realizing optical anti-shake by open-loop translation is disclosed, which includes a lens mount, a lower cover, a focus coil, a translation coil and a magnet. A focus coil is set on the periphery, and four translation coils are evenly spaced on the periphery of the other end. There are 4 magnets, which are respectively arranged on the four inner walls of the yoke corresponding to the positions of the translation coils. same po...
