Lens driving device, camera module and optical apparatus {Lens driving device, camera module and optical apparatus}

This embodiment relates to a lens driving device, a camera module, and an optical device.

The contents described below provide background information on the present embodiment, but do not describe the prior art.

As the distribution of various portable terminals is widely generalized and wireless Internet services are commercialized, consumers' demands related to portable terminals are also diversifying, and various types of additional devices are being installed in portable terminals.

Among them, a typical example is a camera module that takes a picture or video of a subject. Meanwhile, an auto focus (AF) function for automatically adjusting a focus according to a distance to a subject is applied to a recent camera module. Furthermore, an auto focus feedback function is applied to perform the auto focus function more precisely.

However, in a camera module having an autofocus feedback function, it is difficult to form a conductive line for a sensor that detects movement of the lens module due to limitations in internal space.

Meanwhile, through the above-mentioned shape of the shock absorber, disconnection may not occur during a reliability test. In addition, even if the shock absorber is deformed by an impact during a reliability test, interference with the housing 310 may not occur.

Meanwhile, the second sensor unit 720 may be positioned so as not to overlap the FP coil of the third driving unit 420 in the vertical direction.

Hereinafter, the operation of the camera module according to the present embodiment will be described.

First, the auto focus function of the camera module according to the present embodiment will be described. When power is supplied to the coil of the first driving unit 220, the first driving unit 220 moves with respect to the second driving unit 320 due to electromagnetic interaction between the magnets of the first driving unit 220 and the second driving unit 320. At this time, the bobbin 210 to which the first driving unit 220 is coupled moves integrally with the first driving unit 220 . That is, the bobbin 210 coupled to the inside of the lens module moves in the vertical direction with respect to the housing 310 . Since this movement of the bobbin 210 results in the lens module moving closer to or farther from the image sensor, in this embodiment, power is supplied to the coil of the first driving unit 220 to focus on the subject. Adjustment can be performed.

Meanwhile, in the camera module according to the present embodiment, auto focus feedback may be applied for more precise realization of the auto focus function. The first sensor disposed in the housing 310 and provided as a Hall sensor detects a magnetic field of the sensing magnet 715 fixed to the bobbin 210 . Accordingly, when the bobbin 210 moves relative to the housing 310, the amount of the magnetic field sensed by the first sensor changes. The first sensor detects the movement amount of the bobbin 210 in the z-axis direction or the position of the bobbin 210 in this way and transmits the detected value to the controller. The control unit determines whether or not to additionally move the bobbin 210 through the received sensing value. Since this process occurs in real time, the auto focus function of the camera module according to the present embodiment can be performed more precisely through auto focus feedback.

A hand shake correction function of the camera module according to the present embodiment will be described. When power is supplied to the coil of the third driving unit 420, the second driving unit 320 moves with respect to the third driving unit 420 due to electromagnetic interaction between the magnets of the third driving unit 420 and the second driving unit 320. At this time, the housing 310 to which the second driving unit 320 is coupled moves integrally with the second driving unit 320 . That is, the housing 310 moves in a horizontal direction with respect to the base 500 . However, at this time, a tilt of the housing 310 with respect to the base 500 may be induced. At this time, the bobbin 210 also moves integrally with the housing 310. Therefore, since such movement of the housing 310 results in the lens module moving in a direction parallel to the direction in which the image sensor is placed with respect to the image sensor, in this embodiment, power is supplied to the coil of the third driving unit 420 to perform the hand shake correction function.

Meanwhile, hand shake correction feedback may be applied to more precisely realize the hand shake correction function of the camera module according to the present embodiment. A pair of second sensor units 720 mounted on the base 500 and provided as hall sensors sense the magnetic field of the magnet of the second driving unit 320 fixed to the housing 310 . Accordingly, when the housing 310 moves relative to the base 500, the amount of the magnetic field sensed by the second sensor unit 720 changes. The pair of second sensor units 720 detect the movement amount or position of the housing 310 in the horizontal direction (x-axis and y-axis directions) in this way and transmit the detected value to the control unit. The control unit determines whether or not to additionally move the housing 310 through the received sensing value. Since this process occurs in real time, the hand shake correction function of the camera module according to the present embodiment can be performed more precisely through hand shake correction feedback.
