In this embodiment, the side wall 11 protrudes toward the first support frame 2 to form opposite sandwiching walls 14 at intervals, and the magnetic bowl 51 is sandwiched between the two sandwiching walls 14 to be fixed.

The first elastic supporting member 8 elastically connects the fixing frame 1 and the first supporting frame 2 and provides a rotational restoring force for the rotation of the fixing frame 1 around the first direction with respect to the first supporting frame 2.
The second elastic supporting member 9 elastically connects the first supporting frame 2 and the second supporting frame 3 and provides a rotational restoring force for the rotation of the first supporting frame 2 and the fixing frame 1 around the second direction with respect to the second supporting frame 3.
Thus, the above structure can realize the anti-shake function of the Optical Image Stabilization (OIS) of the lens driving apparatus 100.
When the current of the two anti-shake coils 6 is in the same direction when being powered on, the two anti-shake magnetic steels 5 are subjected to the same-direction thrust, and the anti-shake magnetic steels 5 are pushed to drive the fixed frame 1 to rotate around one of the axes perpendicular to the optical axis direction, at this time, because the X axis is opposite to the limitation of the third sliding groove 25 and the fourth sliding groove 33, and the fixed frame 1 itself is not movable, the fixed frame 1 can only rotate along the bobbin where the first sliding groove 13 and the second sliding groove 23 are located with the first support frame 2, that is, the fixed frame rotates around the Y axis parallel to the second direction in the embodiment; when the two anti-shake coils 6 are electrified, the currents are opposite, then the two anti-shake magnetic steels 5 receive the thrust in different directions, then the anti-shake magnetic steels 5 are pushed to drive the fixing frame 1 to rotate around another axis perpendicular to the direction of the optical axis, namely, the fixing frame 1 rotates around the X axis parallel to the first direction in the embodiment, and at the moment, the fixing frame 1 drives the lens module 20 to rotate around the X axis. The arrangement is simple in structure, flexible in response of the rotation restoring force and high in sensitivity.
Due to the action of the first elastic supporting part 8 and the second elastic supporting part 9, when the fixing frame 1 rotates around the X axis, only the first elastic supporting part 8 on the X axis rotates, the second elastic supporting part 9 on the Y axis is not influenced, and the deformation of the first elastic supporting part 8 on the X axis is small due to the fact that the first elastic supporting part 8 on the X axis is very close to the rotating shaft (X axis), so that the rotating restoring force required to be provided by the first elastic supporting part 8 can be reduced to a certain extent, the service life of the lens driving device is prolonged, and the continuous operation of the lens driving device 100 is ensured. Similarly, when the first supporting frame 2 drives the fixing frame 1 to rotate around the Y axis, the rotation restoring force required to be provided by the second elastic supporting member 9 is also reduced, so that the service life of the second elastic supporting member 9 is also prolonged.
Specifically, in the present embodiment, the first elastic supporting members 8 include two and are respectively disposed at intervals along the first direction (X-axis direction) at one set of diagonal positions of the first supporting frame 2. The second elastic supporting members 9 include two and are respectively arranged at intervals along the second direction (Y-axis) at another pair of paired angular positions of the first supporting frame 2. The first elastic supporting piece 8 and the second elastic supporting piece 9 are both plane elastic piece structures perpendicular to the optical axis.
Specifically, each of the first elastic supporting members 8 includes a first fixing arm 81 fixed at one corner of the fixing frame 1, two second fixing arms 82 fixed at two adjacent first side walls 21 of the first supporting frame 2, and two first elastic arms 83 suspending the two second fixing arms 82 and the first fixing arm 81 respectively.
Each of the second elastic supporting members 9 includes a third fixing arm 91 fixed at one corner of the first supporting frame 2, two fourth fixing arms 92 fixed at two adjacent second sidewalls 31 of the second supporting frame 3, and two second elastic arms 93 suspending the two fourth fixing arms 92 and the third fixing arm 91 respectively.
That is, when the currents of the two anti-shake coils 6 are in the same direction when being electrified, the two anti-shake magnetic steels 5 are subjected to the same-direction thrust, and the anti-shake magnetic steels 5 are pushed to drive the fixed frame 1 to rotate around the Y axis parallel to the second direction; when the two anti-shake coils 6 are energized, the currents are reversed, the two anti-shake magnetic steels 5 are pushed in different directions, the anti-shake magnetic steels 5 are pushed to drive the fixing frame 1 to rotate around the X axis perpendicular to the first direction, and then the fixing frame 1 drives the lens cone module 20 to synchronously rotate, so that Optical Image Stabilization (OIS) function compensation of the lens driving device 100 is realized.
Of course, the driving coil and the driving magnetic steel for realizing the Auto Focus (AF) function are similar to the related art structure, and will not be described in detail here.
The lens driving apparatus 100 further includes a housing 30 covering the second support frame 3 for protecting other devices.
The two Hall sensors 10 are respectively installed on one side, close to the anti-shake magnetic steel 5, of the flexible circuit board 7 and electrically connected with the flexible circuit board 7, and are used for detecting the displacement of the fixing frame 1 in the first direction (X-axis direction) and the second direction (Y-axis direction).
Compared with the prior art, the utility model discloses in lens drive device 100, through setting up first elastic support piece 8 and second elastic support piece 9, make first elastic support piece 8 will mount 1 with first braced frame 2 forms elastic connection and does mount 1 winds first direction for first braced frame 2 is rotatory to provide rotatory restoring force, makes second elastic support piece 9 will first braced frame 2 with second braced frame 3 forms elastic connection and for first braced frame 2 winds second direction for second braced frame 3 is rotatory to provide rotatory restoring force to realize the anti-shake function of the Optical Image Stabilization (OIS) of perpendicular to optical axis direction. The first elastic supporting part 8 realizes the degree of freedom of the rotation of the fixed frame 1 and the first supporting frame 2 along an axis parallel to the first direction, and does not influence the second elastic supporting part 9; the second elastic support 9 enables the freedom of rotation of the first support frame 2 and the second support frame 3 along the axis of the second direction without affecting the first elastic support 8, thus forming a free standing elastic support design. Mount 1 is near because first elastic support piece 8 is close to the pivot when the axle that is on a parallel with first direction is rotatory, deformation volume during the rotation is less, thereby the required rotatory restoring force that provides of first elastic support piece 8 has been reduced to a certain extent, thereby its life has been improved, lens drive device 100's continuous operation has been ensured, and in the same way, second elastic support piece 9's life has also been improved, and this setting is simple structure not only, and the rotatory restoring force that provides is nimble moreover, and sensitivity is higher.
The above embodiments of the present invention are only described, and it should be noted that, for those skilled in the art, modifications can be made without departing from the inventive concept, but these all fall into the protection scope of the present invention.
