Description

Technical Field

[0001] This embodiment relates to a lens driving device, a camera module, and optical instruments. Background Technology

[0002] With the widespread adoption of various portable terminals and the commercialization of wireless internet services, consumers' needs related to portable terminals are also diversifying, leading to the installation of various types of add-ons in portable terminals.

[0003] Among these add-on devices are camera modules for capturing subjects as photographs or videos. Meanwhile, optical image stabilization (OIS) to correct for hand shakiness during shooting has been implemented in recent camera modules. Furthermore, with the enhancement of portable terminal functions and the increase in pixel count, the size of image sensors and the aperture of lenses are also increasing.

[0004] However, as the diameter of the lens increases, the stress applied to the support member supporting the OIS drive increases when vibrations and impacts occur in the camera module. This causes the support member to deform and disconnect, resulting in a problem where the OIS cannot be driven and oscillation occurs.

[0005] In addition, when the sensing magnet and sensor are mounted on the coil frame and housing, a problem arises that an error equivalent to the attitude difference deflection of the housing is also detected in the distance between the lens and the image sensor. Summary of the Invention

[0201] In this embodiment, the upper portion of the wire 610 is connected to the first elastic member 510, which serves as a suspension spring, and the lower portion can be connected to the stator 400, such as to the base 410, the substrate 420, or the second coil 430. Due to falling, impact, and vibration, stress is concentrated on the lower portion of the wire 610, and deformation and disconnection may occur as a result. However, in this embodiment, the wire 610 can be provided with a reinforcing structure made of injection-molded material. This eliminates the cumulative fatigue caused by injection molding. Furthermore, the spring constant in the optical axis direction can be increased. Additionally, the spring strength can be increased to raise the resonant frequency, thereby improving the frequency response.

[0202] In a modified embodiment, the wire 610 of the support member 600 may include multiple wires. These multiple wires may be arranged in a twisted manner within the buffer portion 620, such as...

The upper portion can be electrically connected to the first elastic member 510, and the lower portion can be electrically connected to the first substrate 420 or the second coil 430. For electrical connections, communication signals and power signals are connected via the wire 610, and this can be reconnected to the actuator IC or Hall effect device via the first elastic member 510 and the second substrate 330.

[0205] In this embodiment, a damping effect can be achieved due to the injection-molded material. However, when an additional damping effect is required, a first space for applying additional damping (see...) is needed. Figure 14 A) is ensured. A damper disposed in the first space can connect the connecting portion 513 of the first elastic member 510 to the coil frame 210.

[0213] In this embodiment, the spring constant (K) of the first elastic member 510 can be increased, thereby improving the frequency characteristics and the attitude difference in the Z-axis direction (optical axis direction) is improved so that the change in attitude resolution can be reduced, and the feedback system can operate more stably due to the improvement in frequency characteristics.

[0214] The deformable portions, including the first deformable portion 624 and the second deformable portion 625, are based on a circular shape but can have different curvature shapes, and the number of deformable portions can be multiple depending on the characteristics of the product. When the deformable portions are arranged in various configurations, the portion with the maximum displacement can be added during left and right movement to increase stress. The shape of the deformable portions can take forms such as partial bending or clamping.

[0215] The buffer portion 620 may include a groove 626. The groove 626 may be formed by recessing into the outer peripheral surface of the buffer portion 620.

The conductive wire 1610 (including elastic material) can be disposed at the center or exterior of the buffer portion 1620. Welded portions can protrude from the upper and lower portions of the support member 1600. The welded portions can be a first portion 1611 and a second portion 1612 of the wire 1610. The upper portion can be electrically connected to the first elastic member 1510, and the lower portion can be electrically connected to the first substrate 1420 or the second coil 1430.

[0333] In this embodiment, a damping effect can be achieved due to the injection-molded material. However, when an additional damping effect is required, a first space can be provided for applying an additional damper (see [link to documentation]). Figure 36 (A). The damper disposed in the first space can connect the coil frame 1210 and the first elastic member 1510 to the connection portion 1513.

The first fixing portion 1621 of the support member 1600 may be disposed in the hole 1515 of the extension portion 1514. In this case, the diameter of the hole 1515 of the extension portion 1514 in the direction perpendicular to the optical axis may be the same as the diameter of the first fixing portion 1621 of the support member 1600 (see...).

Figure 33 D1 in the figure can be larger than the diameter of the first fixed part 1621 in the direction perpendicular to the optical axis (see [reference]). Figure 33 The diameter D1 of the first deformable portion 1624 in the direction perpendicular to the optical axis can be smaller than the diameter D of the extension portion 1623 in the direction perpendicular to the optical axis.

In this case, the diameter may be the diameter in the direction perpendicular to the optical axis. The diameter D1 of the second deformable portion 1625 may be 20% to 80% of the diameter D of the second fixed portion 1622.

[0341] In this embodiment, the spring constant (K) of the first elastic member 1510 can be increased, thereby improving the frequency characteristics and the attitude difference in the Z-axis direction (optical axis direction) is improved to reduce the change in attitude resolution, and the feedback system can operate more stably due to the improvement in frequency characteristics.

Figure 33 L1 and L2 in the figure can be the lengths of the buffer portion 1620 in the optical axis direction (see [reference]). Figure 33The length of the first deformable portion 1624 and the second deformable portion 1625 in the optical axis direction can be 3% to 40% of the length of the buffer portion 1620 in the optical axis direction. The length of the second groove 1628 of the buffer portion 1620 in the optical axis direction (see...) Figure 33 L2) can be longer than the length of the first groove 1627 in the optical axis direction (see L2). Figure 33 The length of L1).

That is, either the first sensor 1670 or the second sensor 1675 can be disposed between the third sensor 1680 and the fourth sensor 1685.

[0351] Each of the first sensor 1670 and the second sensor 1675 may include a tunnel magnetoresistive (TMR) sensor.

[0353] The lens driving device 1010 may include a third sensor 1680 and a fourth sensor 1685. The third sensor 1680 and the fourth sensor 1685 can be used for OIS feedback control. In this case, the third sensor 1680 and the fourth sensor 1685 can be referred to as "OIS feedback drive sensors". The third sensor 1680 and the fourth sensor 1685 can be disposed in the substrate 1420. The third sensor 1680 and the fourth sensor 1685 can be disposed between the base 1410 and the substrate 1420.

[0356] The lens driving device 1010 according to the second embodiment of the present invention may include the support member 600 of the first embodiment. The support member 1600 of the second embodiment may be replaced with the support member 600 of the first embodiment.

[0357] In this embodiment, OIS movement can be confirmed using a second coil 1430 below the first magnet 1320 or a Hall element on the substrate 1420. Alternatively, AF movement can be determined using a separate second magnet 1650 and a third magnet 1660 via a TMR element or a Hall element.

[0358] In the following description, the connection relationship between the first sensor and the second sensor according to the second embodiment of the present invention will be described with reference to the accompanying drawings.

[0359] Figure 38 This is a conceptual diagram illustrating the connection relationship between the sensors of the lens driving device according to a second embodiment of the present invention.

[0360] A single TMR element or a Hall element can be used to determine AF motion, but in this embodiment, they can be connected in series to increase the linearity of the AF drive distance with respect to the outputs of the Hall and TMR elements. The main Hall element can also be used for Hall calibration, and calibration can be performed using the sum of two values.

[0361] In this embodiment, the first sensor 1670 and the second sensor 1675 can be connected in series. Either output terminal of the first sensor 1670 and either output terminal of the second sensor 1675 can be connected to each other. More specifically, the high-voltage terminal of the two output terminals of the first sensor 1670 and the low-voltage terminal of the two output terminals of the second sensor 1672 can be connected. The first sensor 1670 may include a first terminal as V- and a second terminal as V+. The second sensor 1675 may include a third terminal as V- and a fourth terminal as V+. In this case, the second terminal of the first sensor 1670 and the third terminal of the second sensor 1675 can be connected. The two connected terminals can have the same voltage. Therefore, when the output is measured at the first terminal of the first sensor 1670 and the fourth terminal of the second sensor 1675, approximately twice the output can be measured compared to the case where only one of the first sensor 1670 and the second sensor 1675 is provided.

[0362] At the same time, by changing the circuit connection, two different values ​​can be used to calculate the tilt, and this tilt can be used as information when aligning the lens with the image sensor 1060.

[0363] In the following sections, a comparison of the comparative examples and the present embodiment will be made with reference to the accompanying drawings, and the effects of the present embodiment will be described. However, the comparative examples are also embodiments of the present invention, and the technical configurations corresponding to the comparative examples are not excluded from the present invention.

[0364] Figure 39 This is a conceptual diagram illustrating a posture-dependent lens driving device based on a comparative example; and Figure 40 This is a conceptual diagram illustrating a posture-dependent lens driving device according to a second embodiment of the present invention.

[0365] In such Figure 39 In the model shown in (a), where the sensing magnet is disposed in the coil holder and the driving IC including the Hall element is disposed in the housing, when the coil holder and the housing are in the case of Figure 39 In the UP (upward) orientation illustrated in (b), when the lens is deflected due to gravity in the upward orientation, an AF (attitude difference) can occur (see Figure 1). Figure 39 (b) of A) and the OIS body pose difference in the AF direction (see Figure 39(b) of B). In the case of AF attitude difference A, the attitude difference is related to the weight of the AF drive unit and the spring constant K of the AF spring, and attitude difference correction (closed-loop AF function) can be performed through displacement and Hall element calibration. However, in the case of OIS body attitude difference B in the AF direction, the attitude difference is related to the suspension spring and the spring constant K of the OIS body, which are the OIS drive part, and is not corrected in the comparative example. At the same time, in the case of... Figure 39 As illustrated in (c), in the side (lateral) orientation with the lens facing laterally, the OIS body orientation difference in the body direction (see Figure 1). Figure 39 The C of (c) is related to the spring constant K of the OIS wire and the OIS body, which are the driving parts of the OIS. The attitude difference can be corrected (centering function) by calibrating the displacement and the Hall element of the OIS.

[0366] In this embodiment, the wire can be reinforced by injection molding and the sensor can be disposed in the base 1410. In this embodiment, as... Figure 40 As shown in (a), in the UP posture with the lens facing upward, a movement can occur in the first mover 1200, which is the AF drive unit, due to the first length (see Figure 1200). Figure 40 The deflection caused by (a) of (a). Additionally, in this embodiment, as... Figure 40 As shown in (b), in the SIDE orientation with the lens facing laterally, a near-zero value can be generated in the AF actuator by the second length (see Figure 1). Figure 40 The deflection caused by (b) of (b). Meanwhile, in this embodiment, as Figure 40 As shown in (c), in the down (down) orientation with the lens facing downwards, a third length (see Figure 1) can be generated in the AF actuator. Figure 40 The deflection caused by (c) of (c). At this time, the first length can be approximately equal to the third length.

[0367] In this embodiment, refer to Figure 39 The attitude difference in the OIS body in the AF direction described can be corrected. Since the first sensor 1670 and the second sensor 1675 for detecting the second magnet 1650 and the third magnet 1660 are provided in the base 1410, the attitude difference of the OIS body (corresponding to the second mover 1300) in the AF direction can also be taken into account.

[0368] In this embodiment, the upper suspension portion of the first elastic member 1510 is eliminated by using a support member that applies injection material and wire together, or the spring constant K of the first elastic member 1510 is increased, so that the deflection of the first mover 1200 and the second mover 1300 according to the posture can be reduced.

[0369] Minor variations may occur due to spring K distribution, wire length, and assembly tolerances such as tilt. Feedback, such as an AF Hall effect sensor, can be used to correct AF deflection. In the suspension portion (corresponding to the extension 1514 of the first elastic member 1510) used to suppress OIS wire disconnection and improve frequency characteristics, the K value can be increased, and stress can also be increased, as attitude difference is reduced. An appropriate K value is required to suppress wire spring disconnection, and this results in an attitude difference of approximately 2 μm to 20 μm.
