Also, the Hall sensor portion may be provided at a lower end of the inner surface of the yoke portion, and a terminal groove portion corresponding to the terminal portion may be formed on the end surface of the yoke portion so that the terminal portion is exposed to the outside.

The second magnet may be formed to have a size that does not affect the magnetic flux density of the first magnet portion corresponding to the electromagnetic force for driving the coil portion

The upper spring is coupled to the upper surface of the yoke 220 and the upper surface of the bobbin 110 to support the bobbin 110. The upper spring supports the bobbin 110 and the yoke 220 to provide a return force when the bobbin 110 moves upward. As shown in FIG. Specifically, the upper spring is disposed at the upper end of the yoke 220, and protrudes a predetermined width in an inner circumferential direction from an opening formed in the upper end, and the protruding portion supports the upper end side of the bobbin 110.

Here, the yoke 220 may be formed of a metal material, so that an insulating plate 224 of insulating material may be provided between the yoke 220 and the upper spring. Further, a cover 225 formed in a shape corresponding to the side of the yoke 220 may be mounted on an upper end of the upper spring.

The upper surfaces of the lid 225, the upper spring, the insulating plate 224, and the yoke 220 may have holes corresponding to each other and may be fastened with an adhesive or the like.

The rim of the lower spring is supported on the upper surface of the base 230 and supports the lower end side of the bobbin 110 on the inner circumferential side. Specifically, the lower spring may be formed of two corresponding leaf springs, and may be electrically connected to one end and the other end of the coil part 120 wound on the bobbin 110 to transmit power to the coil part 120 have. That is, the lower spring may be formed as a leaf spring symmetrically with respect to the optical axis, and may be formed as a separate leaf spring for input / output of the power source.

The magnetic body 500 is mounted on the first magnet part 210 and is positioned between the first magnet part 210 and the coil part 120. The magnetic part 500 is inserted into the coil part 120, ) To provide a friction force.

The magnetic body 500 may be formed of a metal such as an iron plate so as to be attached to the first magnet part 210. The magnetic body 500 may be formed of a metal such as a metal, By supporting the spacing space, it is possible to reduce the posture difference (defect of the mover 100) due to the change of the position of the lens driving motor. Accordingly, it is preferable that at least two of the magnetic bodies 500 are mounted so as to face each other on the inner side of the first magnet part 210.

Therefore, the positional difference is reduced by the magnetic body 500 by the lens driving motor, and continuous power supply to the coil portion is unnecessary in order to maintain the lens portion at a specific position. Further, since the magnetic body 500 also functions as an elastic unit, it is possible to realize a lens driving motor without a separate elastic unit, thereby making it possible to downsize the optical axis direction and efficiently operate the internal space.

The image sensor (not shown) may be mounted on the central portion of the upper surface of the printed circuit board so as to be positioned along the optical axis direction with at least one lens (not shown) accommodated in the lens portion 10. Such an image sensor converts an optical signal of an object incident through a lens into an electrical signal.

The adhesives described above may be embodied as thermosetting epoxy or UV epoxy and cured by exposure to heat or UV. However, if a thermosetting epoxy is used, it is cured by moving to an oven or by applying heat directly. When UV (ultraviolet) epoxy is used, the adhesive is cured by applying UV (ultraviolet rays).

In addition, the adhesive may be an epoxy which can be mixed with thermosetting and UV (ultraviolet ray) curing, and may be thermosetting or UV (ultraviolet) curing. The adhesive is not limited to the epoxy but can be replaced with any substance that can be bonded.
