When the anti-shake structure of the present application is used, since the reed assembly 40 is electrically connected with the bottom plate assembly 30 and both ends of the first wire 50 are respectively electrically connected with the reed assembly 40 and the bottom plate assembly 30, when the first wire 50 is electrically contracted, the first wire 50 can drive a part of the structure of the reed assembly 40 to move relative to the bottom plate assembly 30, thereby driving the frame assembly 60 to move in the XY plane, and further driving the lens support 70 to move through the frame assembly 60, so as to realize the optical anti-shake effect. Meanwhile, since the AF driving assembly 80 is electrically connected with the reed assembly 40 through the frame assembly 60, when the AF driving assembly 80 is energized, the AF driving assembly 80 drives the lens support 70 to move relative to the frame assembly 60, so as to achieve AF driving. And since the first wire 50 is plural, the frame assembly 60 can be rotated in the XY plane or moved along the X-axis and/or the Y-axis. Meanwhile, since the frame assembly 60 in the present application can be electrically connected through the reed assembly 40, the internal structure is simplified as compared with the conventional image pickup apparatus. Therefore, the anti-shake structure effectively solves the problem that the anti-shake structure of the image pickup device in the prior art is poor in service performance.

Specifically, the circumferential inner side wall of the frame assembly 60 has a plurality of first slide grooves 61, the first slide grooves 61 are spirally raised along the Z-axis, and the lens support 70 moves along the first slide grooves 61 when the AF driving assembly 80 is energized.

In the present application, the movement direction of the lens support body 70 can be limited by the cooperation of the first sliding groove 61 and the second sliding groove 71, so that it is ensured that the lens support body 70 can move along a predetermined direction after the AF driving assembly 80 is powered on, and thus the usability of the anti-shake structure of the present application is effectively ensured. Also, since the first balls 90 are clearance-fitted with the ball inclined surfaces 72, the lens support body 70 can be effectively prevented from being jammed during the movement relative to the frame. When the magnetic attraction force is not exerted, the balls are in clearance fit in the space surrounded by the first sliding groove and the second sliding groove or the ball inclined plane. When subjected to circumferential magnetic attraction, the lens support 70 rotates slightly, bringing the balls against the force side.

Specifically, the rotation directions of the plurality of first slide grooves 61 are the same. By this arrangement, it is possible to effectively ensure that the lens support body 70 can perform a movement in a predetermined direction with respect to the frame assembly 60, and to prevent the engagement of the plurality of first slide grooves 61 and second slide grooves 71 from occurring a seizing phenomenon.

Alternatively, the angle between the connecting line of the two ends of the first chute 61 and the Z-axis direction is 45 degrees.

Alternatively, the lengths of the plurality of first slide grooves 61 in the Z-axis direction are the same.

And in the present embodiment, at least two first balls 90 are provided in each first slide groove 61. When only two first sliding grooves are formed, at least two first rolling balls are placed in the corresponding grooves to support the lens support body so that the lens support body can stably lean against the rolling balls and cannot incline.

In one embodiment of the application, not shown, the number of first slide grooves 61 is three, and the three first slide grooves 61 are respectively provided at three different corners of the frame assembly 60. Moreover, the frame assembly 60 is quadrilateral, each corner of the frame assembly 60 is respectively provided with an avoidance notch 62, the corner of the lens support body 70 is provided with a guide protrusion 73 corresponding to the avoidance notch 62, a movement gap is formed between the avoidance notch 62 and the guide protrusion 73, the anti-shake structure further comprises a magnetizer 100 and an adsorption magnet 110 which are matched with each other, three first sliding grooves 61 are respectively arranged on the inner side walls of the three different avoidance notches 62, one of the magnetizer 100 and the adsorption magnet 110 is arranged on the inner side wall of the avoidance notch 62 without the first sliding groove 61, and the other one of the magnetizer 100 and the adsorption magnet 110 is correspondingly arranged on the lens support body 70.

In the present embodiment, by providing the magnetizer 100 and the adsorption magnet 110, it is possible to ensure that the second slide groove 71 or the ball slope 72 of the lens support body 70 can approach toward the first slide groove 61, thereby ensuring that the lens support body 70 does not tilt, and facilitating the stability of the optical axis of the lens provided on the lens support body 70. Secondly, through setting up magnetizer 100 and absorption magnetite 110, can also guarantee when AF drive assembly 80 is different electricity, lens support 70 can be under magnetizer 100 and absorption magnetite 110's interact quick reset, that is to say magnetizer 100 and absorption magnetite 110's cooperation can also provide certain restoring force to the initial position for lens support 70.

In the present application, the plurality of reed bodies 41 are provided to realize high precision and stable control, and different circuit-on functions can be realized by different reed bodies 41. Namely, some reed bodies 41 are electrically connected with the frame assembly 60 to realize the circuit conduction of the AF driving assembly 80, and some reed bodies 41 are electrically connected with the first silk thread 50 to realize the circuit conduction of the OIS anti-shake driving circuit, so that the FPC is replaced by the FPC to be electrified, the number of parts is reduced, the internal structure of the anti-shake structure can be effectively simplified, and the assembly process and difficulty can be simplified.

Specifically, the reed body 41 includes a body portion 411 and a connecting arm 412. The body 411 is movably arranged at one side of the bottom plate assembly 30 away from the base 20; one end of the connection arm 412 is connected to an end of the body 411, and the other end of the connection arm 412 extends around an edge of one side of the body 411 and is electrically connected to the bottom plate assembly 30. And, the reed assembly 40 further includes a plurality of upper jaws 42, at least one upper jaw 42 is provided on each of the plurality of reed bodies 41 electrically connected to the first wire 50, and the first wire 50 is connected to the reed body 41 through the upper jaws 42. And the base plate assembly 30 includes a circuit connection member 31 and a lower jaw 32, and the reed body 41 is electrically connected to the circuit connection member 31; the lower jaw 32 is provided in plurality, the lower jaw 32 is electrically connected with the circuit connection member 31, and the first wire 50 is electrically connected with the lower jaw 32.

In one embodiment of the present application, the circuit connection 31 includes a plurality of first powered pins, the different first powered pins being electrically connected to different reed bodies 41 or different lower jaws 32, respectively. Preferably, the end of the connection arm 412 is soldered to the first powered pin. By this arrangement, one end of the connecting portion can be made to deflect toward one side of the circuit connection member 31 and away from the frame assembly 60, thereby enlarging the gap between the connecting arm 412 and the frame assembly 60, and further effectively avoiding contact between the connecting arm 412 and the frame assembly 60 during the movement of the frame assembly 60 along with the body portion 411.

Optionally, two first wires 50 on adjacent sides of the base plate assembly 30 are electrically connected to the same upper jaw 42 or the same lower jaw 32, respectively.

In one embodiment of the present application, the number of the reed bodies 41 and the number of the first wires 50 are four, the four reed bodies 41 are disposed at the corners of the bottom plate assembly 30 in a pair-by-pair manner, the four first wires 50 are disposed at different sides of the bottom plate assembly 30 in a pair-by-pair manner, wherein two reed bodies 41 are electrically connected with two adjacent first wires 50 respectively, and the other two reed bodies 41 are electrically connected with the frame assembly 60 respectively. And, two adjacent reed bodies 41 among the four reed bodies 41 are symmetrically disposed with the other two adjacent reed bodies 41. Of course, in the present embodiment, the upper and lower claws 42 and 32 are each two, the two upper claws 42 are oppositely disposed on one diagonal, and the two lower claws 32 are oppositely disposed on the other diagonal. And, both ends of the first wire 50 are connected to the adjacent upper and lower jaws 42 and 32, respectively. Since the lower jaw 32 is fixed to the circuit connection member 31 and the upper jaw 42 is provided on the reed body 41 and moves together with the reed body 41, when energized, the first wire 50 contracts and moves the upper jaw 42, thereby moving the reed body 41 through the upper jaw 42 and further moving the frame assembly 60. Therefore, in the present embodiment, by controlling the energization amounts of the different first wires 50, different movement patterns of the frame assembly 60 can be realized, thereby realizing the anti-shake adjustment of the lens on the lens support 70 on the frame assembly 60.

Of course, in the present application, the number of the first wire 50, the reed body 41, the upper jaw 42 and the lower jaw 32 can be adaptively adjusted according to different practical situations and use requirements.

Preferably, the upper jaw 42 is of unitary construction with the reed body 41. Of course, in the present application, the upper jaw 42 and the reed body 41 may be separated from each other.

Optionally, the base plate assembly 30 further includes a plurality of support blocks 33, the support blocks 33 are disposed on a side of the circuit connection member 31 facing the reed bodies 41, and each reed body 41 corresponds to at least one support block 33.

Preferably, the bottom plate assembly 30 further comprises a plurality of second balls 34, at least one mounting groove 331 is arranged on the side, facing the reed body 41, of the supporting block 33, at least one second ball 34 is arranged in each mounting groove 331, and the side, facing the bottom plate assembly 30, of the reed body 41 is abutted against the second balls 34. By this arrangement, when the reed body 41 moves under the action of the first wire 50, since the second ball 34 supports the reed body 41, the friction force applied to the reed body 41 can be effectively reduced, and thus the moving components of the reed body 41 can be reduced. In addition, the driving resistance can be reduced by the arrangement, so that the corresponding speed of the anti-shake structure is improved, and the driving power consumption of the driving device is reduced.

From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:
