4A is an assembled perspective view of a fixing component in a photographic module in accordance with an exemplary embodiment of the present invention. 4B is an exploded perspective view of a fixing member in a photographic module according to an exemplary embodiment of the present invention.

One or more ball bearings 800 and fixing members 400 provided in the photographic module 1000 according to an exemplary embodiment of the present invention will be described hereinafter with reference to FIGS. 4A and 4B.

In a situation where the user's hand shake occurs, the hand shake correction member 520 can move or drive the drive member 300 in the horizontal direction (X direction and Y direction) to correct the hand shake.

Here, when the driving member 300 is driven in the horizontal direction (X direction and Y direction), deformation of the suspension 700 such as warpage or the like may occur. Therefore, the driving member 300 can be tilted. As a result, the drive tilt can be caused. Here, the term "driving tilt" means the tilt of the lens according to the inclination of the driving member. Further, in a situation where an external impact such as a drop impact or the like occurs, there may be a risk that the driving tilt may occur due to deformation of the suspension wire 700.

Therefore, in the photographic module 1000 according to an exemplary embodiment of the present invention, one or more ball bearings 800 may be disposed between the fixed member 400 and the driving member 300 in order to prevent driving tilt caused by deformation of the suspension wire 700.

A plurality of ball bearings 800 may be disposed between the fixed member 400 and the driving member 300 to support the driving member 300 and the fixing member 400.

Here, since the plurality of suspension wires 700 support the driving member 300, the driving member 300 and the fixing member 400 are disposed to be spaced apart from each other in the optical axis direction (Z direction) and the plurality of ball bearings 800 are disposed on the driving member 300 and fixed In the state in the gap between the members 400, the gap in the optical axis direction (Z direction) between the driving member 300 and the fixed member 400 can be maintained by the plurality of suspension wires 700 and the plurality of ball bearings 800.

In addition, since one end of the suspension wire 700 and the other end are respectively fixed Or coupled to the fixing member 400 and the elastic member 600, the plurality of ball bearings 800 can be continuously contacted with or disposed between the driving member 300 and the fixing member 400, and cannot be coupled with the driving member 300. The spaces between the fixing members 400 are separated.

In addition, even in the case where an external impact to the photographing module 1000 or the like occurs, the gap in the optical axis direction (Z direction) between the driving member 300 and the fixed member 400 is maintained by the driving member 300. The state is supported by a plurality of ball bearings 800, so that deformation of the suspension wire 700 can be prevented. Therefore, the driving member 300 can be stably moved in the horizontal direction (X direction and Y direction).

The fixing member 400 may include a sensor housing 430, a substrate 420 attached to an upper surface of the sensor housing 430, and a fixing frame 410 attached to an upper surface of the substrate 420.

The fixed frame 410 may be provided with a receiving member 411 that houses a plurality of ball bearings 800.

In an exemplary embodiment, the receiving member 411 may have a shape that passes through the hole of the fixing frame 410, but is not limited thereto.

Therefore, the plurality of ball bearings 800 can be housed in the accommodating member 411 to contact the substrate 420, and can be respectively disposed to partially protrude outward from the accommodating member 411.

Therefore, the ball bearing 800 can contact the driving member 300 and the substrate 420.

The receiving member 411 may be larger than the diameter of the ball bearing 800. Therefore, the ball bearing 800 can roll in the accommodating member 411 while being in contact with the driving member 300 and the substrate 420.

The substrate 420 may be coupled to a lower portion of the fixed frame 410 and may have an upper surface to which the second coil 525 is attached.

Here, the fixing frame 410 disposed on the substrate 420 may have a receiving groove 415 formed therein to accommodate the second coil 525 in the receiving groove 415.

Therefore, the second coil 525 may be disposed to face the second magnet 521 attached to the lower surface of the driving member 300 in the optical axis direction (Z direction).

At the same time, a plurality of suspension wires 700 may pass through the penetration holes 417 formed in respective corners of the fixed frame 410 and then may be soldered to the substrate 420.

Next, the configuration of the plurality of ball bearings 800 will be described.

The surface of the substrate 420 that contacts the plurality of ball bearings 800 can be provided as, for example, but not limited to, a flat or concave surface.

Therefore, when the driving member 300 moves in the horizontal direction (X direction and Y direction), the ball bearing 800 can roll between the driving member 300 and the fixing member 400.

Since the driving member 300 is constantly in point contact with the plurality of ball bearings 800, the driving members can be stably driven in the horizontal direction (X direction and Y direction).

In addition, since the driving member 300 contacts the plurality of ball bearings 800 and is thus supported, deformation or breakage of the suspension wire 700 may not occur even in the event of an external impact on the photographic module 1000 or the like. Therefore, the driving characteristics and durability of the hand shake correction member 520 can be improved.

In an exemplary embodiment, at least three ball bearings 800 can be provided. In addition, the number of receiving members 411 accommodating the plurality of ball bearings 800 may correspond to the number of ball bearings 800.

In the case where three ball bearings 800 are provided, the ball bearings may be disposed to be spaced apart from each other by a gap while having an angle of 120 degrees between the ball bearings based on the optical axis.

However, the technical spirit of the present invention is not limited to the number of ball bearings 800 and the gap between the ball bearings 800. That is, as long as the ball bearing 800 can support the driving member 300, the number of the ball bearings 800 and the gap between the ball bearings 800 are not limited.

Meanwhile, the plurality of ball bearings 800 may be formed of, for example, but not limited to, metal, and there may be a contact surface of the contact ball bearing 800 of the substrate 420 under the condition that an external impact on the photographic module 1000 or the like occurs. The risk of depression.

Therefore, in the photographic module 1000 according to an exemplary embodiment of the present invention, the substrate 420 may have a separate support pad (not shown) disposed on an upper surface thereof, and a support pad (not shown) may accommodate The receiving member 411 is in contact with the plurality of ball bearings 800.

Here, the support pad (not shown) may be formed of metal, similar to the condition of the plurality of ball bearings 800.

Next, according to an exemplary embodiment of the present invention, a driving operation of the driving member 300 in the horizontal direction (X direction and Y direction) will be described. However, with regard to the driving operation of the driving member 300, for the convenience of explanation, FIGS. 5A to 5D only explain the driving operation of the driving member 300 in the X direction among the horizontal directions (the X direction and the Y direction). FIG. 5A is a schematic cross-sectional view showing a form in which the driving member 300 is relatively moved with respect to the fixed member 400 in a state where it is supported by the plurality of suspension wires 700 in the optical axis direction.

In addition, FIG. 5B is a schematic cross-sectional view showing a form in which the driving member 300 is supported in the optical axis direction by a plurality of suspension wires 700 and a plurality of ball bearings 800 in the photographic module according to an exemplary embodiment of the present invention. 5C and 5D are schematic cross-sectional views showing a form in which the driving member 300 is driven in a direction perpendicular to the optical axis direction in the photographic module according to an exemplary embodiment of the present invention.

Since one end of the suspension wire 700 is fixed to the fixing member 400 and the other end thereof is fixed to the elastic member 600, one end of the suspension wire 700 may be a fixed end and the other end of the suspension wire 700 may be a driving end.

Therefore, in order to correct hand shake, the plurality of suspension wires 700 can be rotated when the driving member 300 is driven in the horizontal direction (X direction and Y direction).

For example, since the elastic member 600 is attached to the driving member 300, when the driving member 300 is driven in the horizontal direction (X direction and Y direction), the elastic member 600 may be driven together with the driving member 300. Here, since one end of the suspension wire 700 is fixed to the fixing member 400 to be held or coupled in a fixed state, and the other end of the suspension wire is fixed to the elastic member 600 to be driven together with the elastic member 600, Therefore, the other end of the suspension wire 700 is rotatable around one end of the suspension wire 700 fixed to the fixing member 400.

Referring to FIG. 5A, in a state where the driving member 300 and the fixing member 400 which are spaced apart from each other in the optical axis direction (Z direction) are supported by only a plurality of suspension wires 700, the horizontal direction of the correction member 520 can be shaken by the hand (X). The driving force in the direction and the Y direction drives the driving member 300 in both the horizontal direction (the X direction and the Y direction) and the optical axis direction (the Z direction).

That is, the elastic member 600 to which the other end of the plurality of suspension wires 700 is fixed and the driving member 300 can be rotated by the rotation of the suspension wire 700. Therefore, the driving member 300 can be driven in both the horizontal direction (the X direction and the Y direction) and the optical axis direction (the Z direction).

However, as shown in FIGS. 5B to 5D, in the photographic module 1000 according to an exemplary embodiment of the present invention, the driving member 300 and the fixing member which are disposed to be spaced apart from each other in the optical axis direction (Z direction) are disposed. 400 can be a plurality of ball bearings 800 And a plurality of suspension wires 700 are supported.

Therefore, even in a state where the plurality of suspension wires 700 are rotated, the gap between the driving member 300 and the fixing member 400 in the optical axis direction (Z direction) can be constantly maintained by the plurality of ball bearings 800, so that the suspension wire 700 The elastic member 600 to which the other end is fixed is elastically deformable in the optical axis direction.

That is, when the suspension wire 700 is rotated, portions of the elastic member 600 to which the other end of the plurality of suspension wires 700 are fixed are movable in the optical axis direction (Z direction).

When the driving member 300 is driven in the horizontal direction (X direction and Y direction), the elastic member 600 is elastically deformed in the optical axis direction (Z direction), so that the pressure directed to the fixing member 400 can be generated in the elastic member 600. As a result, pressure can be applied to the driving member 300 coupled to the elastic member 600 to move toward the fixing member 400.
