Although it is possible to improve the movable region of the lens by supporting the lens supporting portion by the ball type supporting method, if the movable region becomes large, the shift from the optical axis becomes large, and the shift tilt characteristic may be deteriorated. The conventional ball-type ball holding mechanism is insufficient in dealing with the horizontal deviation of the optical axis, and therefore, it is necessary to solve this problem.

Further, the devices may be otherwise positioned (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
Fig. 1 illustrates a cross-sectional view of a lens driving apparatus of a ball-type voice coil motor for auto-focusing according to one embodiment of the present disclosure.
As shown in fig. 1, the lens driving device 100 of the ball-type voice coil motor may include a lens supporting part 110, a base 120, a voice coil motor device 130, and guide balls 140.
The lens support part 110 serves to support at least one lens and moves in an optical axis direction of the lens to perform focusing. For example, a lens may be provided at a hollow position of the lens support part 110.
The voice coil motor device 130 may include a permanent magnet 131, a coil 132, and a magnetic plate 133, and the voice coil motor device 130 is used to move the lens support part 110 to a focal position of the lens in an optical axis direction (a direction perpendicular to the paper surface in fig. 1). The magnetic plate 133 is made of a material capable of forming a magnetic force with the permanent magnet 131.
The guide balls 140 are plural in number and serve to guide the movement of the lens support part 110.
The base 120 is used to support the lens support part 110, the voice coil motor device 130 and the guide balls 140.
The permanent magnet 131 is disposed on one side of the lens support part 110, and a guide ball holding mechanism in which the guide balls are held by the permanent magnet 131 and a magnetic plate 133 fixed to the base is provided at two corner positions of the side part of the lens support part 110 on the opposite side of the one side.
Fig. 2 shows a schematic view of a lens support according to one embodiment of the present disclosure.
The lens support part 110 may include a hollow part 111 and a side frame part 112 surrounding the hollow part 111. The hollow portion 111 provides a space for mounting the lens, and the side frame portion 112 provides a support for the lens.
The lens support 110 may also be provided with a guide ball retaining mechanism 113. According to a preferred embodiment of the present disclosure, the number of the guide ball holding mechanisms 113 is two, and the two guide ball holding mechanisms 113 may be disposed at both corner ends of the same side of the lens support part 110. In fig. 2, the guide balls are shown in a dotted line form, which are not a part of the lens support part 110, and are shown here only for convenience of explanation.
The guide ball retaining mechanism 113 may be shaped as a recess that can accommodate a ball.
The concave portion may provide stress F to the ball toward the lens optical axis center OL when the permanent magnet 131 is attracted to the magnetic plate 133 so that the center OL of the lens support part 110 is maintained at the optical axis center when the concave portion comes into contact with the ball.
For example, in fig. 2, the ball 140 may be provided with the stress F toward the optical axis center OL by the contact surface 1131 of the concave portion. Wherein the shape of the contact surface 1131 is preferably set to a planar shape, the planar direction of which may be perpendicular to the connecting line of the optical axis center OL, for example, by the stress F.
The recess may also have another contact surface 1132 that may contact the ball 140, which defines the position of the ball 140 by cooperating with the contact surface 1131. Of course, the recess may also have other contact surfaces, for example the contact surface on the upper side of the ball in fig. 2.
In addition, the lens support part 110 may have a position where the permanent magnet 131 is disposed on the opposite side of the ball disposition side. That is, the permanent magnets 131 are disposed on the opposite side (e.g., the lower side as viewed in fig. 2) of the ball disposition side.
Fig. 3 shows a schematic view of a base according to an embodiment of the present disclosure.
The base 120 may include a bottom portion 121 and a sidewall portion 122. Wherein the side wall portion 122 extends from the periphery of the bottom portion 121 by a certain length to form a space for accommodating the lens support portion 110.
Among them, a protrusion 123 may be provided on an inner wall (a wall surface facing the lens support part 110) of the side wall part 122. The protrusion 123 holds the ball 140 together with the concave portion of the lens support part 110. In fig. 3, the guide balls are shown in dashed lines, which are not part of the base 120, and are shown here for ease of illustration only.
The protrusion 123 has a contact surface 1231 that contacts the ball. The contact surface 1231 works together with the contact surface of the concave portion of the lens support portion 110 to hold the ball.
In a preferred embodiment of the present disclosure, the contact surface 1231 may be a plane. For example, as shown in fig. 1, the planar direction of the plane may be at an angle of 45 ° to the direction of the magnetic attraction force M between the permanent magnet 131 and the magnetic plate 133.
As shown in fig. 1 and 3, the plane directions of the contact surfaces 1231 of the two balls each make an angle of 45 ° with the direction of the magnetic attraction force M between the permanent magnet 131 and the magnetic plate 133.
Thus, with the 45 ° angle setting, when the magnetic plate 133 attracts the permanent magnet 131, that is, attracts the lens support 110, the lens support 110 can move by a force toward the center of the optical axis, so that the lens support 110 is always held on the center of the optical axis, that is, the center of the lens support 110 always coincides with the center of the optical axis when moving in the direction of the optical axis.
Fig. 4 shows a schematic diagram of a voice coil motor arrangement according to one embodiment of the present disclosure.
Wherein fig. 4a shows a top cross-sectional view of the voice coil motor and fig. 4b shows a side cross-sectional view of the voice coil motor.
The voice coil motor device 130 may include a permanent magnet 131 (not shown in fig. 4, please refer to fig. 1), a coil 132, and a magnetic plate 133, and the voice coil motor device 130 is used to move the lens support part 110 to the focal position of the lens in the optical axis direction. When the coil 132 is energized, a magnetic field generated by it interacts with the permanent magnet 131 (magnetic attraction force and repulsion force), so it can move the lens support portion 110 in the optical axis direction.
The coil 132 may be in the form of a toroidal coil. The driver chip 134 is located in the inner peripheral side of the coil 132 constituting the voice coil motor device. This makes it possible to appropriately arrange the driver chip 134 without causing hindrance to other components and the like. The driver chip 134 is used to control the current supplied to the coil 132 to control the voice coil motor device.
A hall detection unit 135 may be further included, and the hall detection unit 135 detects the position of the lens support part 110 by a change in the magnetic field of the permanent magnet 131. The hall detecting unit 135 may also be provided in the inner peripheral side of the coil 132.
In the present disclosure, one side of the coil 132 is disposed opposite to the permanent magnet 131, the other side of the coil 132 is connected to one side of a flexible circuit board (FPC)136, and the other side of the flexible circuit board 136 is disposed with the magnetic plate 133. The coil 132, the driving chip 134 and the hall detection unit 135 are all point-connected to the flexible circuit board 136 so as to be connected to an external circuit through a port 1361 of the flexible circuit board 136 to supply a current or input/output signals, etc.
Fig. 5 illustrates a right side cross-sectional view of fig. 1 according to one embodiment of the present disclosure.
The guide ball 140 may include a plurality of balls, and as shown in fig. 5, the guide ball 140 includes three balls, i.e., an upper ball 1401, a middle ball 1402, and a lower ball 1403.
The diameters of the upper ball 1401 and the lower ball 1403 may be the same, and the diameter of the middle ball 1402 may be smaller than the diameters of the upper ball 1401 and the lower ball 1403. The upper ball 1401 and the lower ball 1403 are in contact with the respective contact surfaces, so that smooth sliding of the lens support 110 in the optical axis direction is ensured, and the middle ball 1402 ensures smooth sliding between the upper ball 1401 and the lower ball 1403.
Although the structure of one guide ball is shown in fig. 5, the structure of the other guide ball may be the same.
In the above-described embodiment of the present disclosure, the voice coil motor apparatus 130 may share the permanent magnet 131 with the position detection apparatus, and thus the number of parts may be reduced, thereby achieving cost reduction.
Further, the length of the permanent magnet 131 may be set to be the same as or substantially the same as (slightly smaller than) that of one side surface of the lens support part 110, and the length of the coil may be set to be the same as or substantially the same as (slightly smaller than) that of the side wall part 122 of the base 120. This ensures that the space of the voice coil motor device 130 is secured without increasing the size of the driving device, and thus sufficient driving force can be provided even by a set of voice coil motor devices 130.
A structure for comparison will be described with reference to fig. 6. In the structure shown in fig. 6, the guide balls are disposed on the same side as the voice coil motor device, so that the guide balls will occupy the space of the voice coil motor device, and if they are disposed on the same side, the lens support portion will be caused to wobble in the optical axis direction and in the plane direction perpendicular to the optical axis. If the space available for the voice coil motor device is reduced, the driving force will be weakened. If the shake occurs, the optical axis is deviated or inclined.
Therefore, according to the embodiments of the present disclosure, it is possible to provide a sufficient driving force, and to avoid occurrence of a situation of inclination and optical axis deviation, and it is possible to reduce the cost and the like.
According to another aspect of the present disclosure, there is provided a camera apparatus including: the lens driving device described above; at least one lens fixed in the lens support part; and an image sensor receiving light passing through the at least one lens.
According to another aspect of the present disclosure, there is provided an electronic apparatus including the above-described camera device. The electronic device is, for example, a mobile phone, a tablet, or a vehicle-mounted device.
