In order to solve the problem that the use performance of the camera device is poor in the prior art, the application provides an anti-shake structure, an anti-shake system and the camera device.
The camera device comprises an anti-shake system, and the anti-shake system comprises an anti-shake structure. Through using the anti-shake system in this application, can improve camera device's anti-shake performance effectively, avoid appearing using camera device to shoot out fuzzy, unclear image.

With the anti-shake structure having the above-described structure, since the plurality of balls 70 are provided between the lens support 30 and the frame 40, when the lens support 30 moves in the Z direction with respect to the frame 40, it is possible to ensure more flexible movement of the lens support 30 by the balls 70 and also to reduce the frictional force between the lens support 30 and the frame 40. Since the lens support 30 is further provided with the guide post 31, the ball 70 is simultaneously contacted with the guide post 31 and the frame 40 in the process that the lens support 30 moves relative to the frame 40, so that the stability of the movement of the ball 70 is ensured, and the stability of the movement of the lens support 30 is further ensured. Therefore, through the arrangement, the shaking of the lens support body 30 in the process that the lens support body 30 moves relative to the frame 40 can be reduced, the stability of the lens support body 30 is ensured, and therefore, the picture shot by the camera device can be ensured to be more stable. Consequently, the anti-shake structure in this application has solved the poor problem of camera device performance among the prior art effectively.
Specifically, the side of the frame 40 corresponding to the side of the lateral coil 60 has a receiving groove 41 for receiving the ball 70, the receiving groove 41 opens toward the guide post 31, and the receiving groove 41 extends along the Z direction. Through setting up the accommodation groove 41, can be spacing to ball 70 effectively to guarantee that ball 70 only can rotate in accommodation groove 41, and can not appear removing relative lens supporter 30 or frame 40, thereby guaranteed the holistic stability of anti-shake structure.
In one embodiment of the present application, the frame 40 has receiving grooves 41 at two corners of a side corresponding to the side of the lateral coil 60, and the notches of the two receiving grooves 41 are oriented in the same direction.

Preferably, the plurality of balls 70 in the receiving groove 41 are arranged in two rows, and the plurality of balls 70 in each row are arranged along the extending direction of the receiving groove 41, and the two rows of balls 70 are spaced from each other and are respectively located at two sides of the guide column 31. Meanwhile, the diameters of two balls 70 at both ends of the plurality of balls 70 in the same row in the same receiving groove 41 are larger than or equal to the diameters of the other balls 70.
In one embodiment of the present application, the number of the balls 70 in each row in the receiving groove 41 is 3, and the diameter of the ball 70 positioned in the middle of the 3 balls 70 is smaller than the diameters of both ends. By such an arrangement, it is ensured that the balls 70 in the middle do not cause frictional resistance, thereby ensuring smoother movement of the lens support 30. Of course, in practice, the number of balls 70 per row is not limited to 3, and the size of 2 is not limited to 1.
Further, the upper 4 rows of balls 70 may be provided at each of the four corner sides of the lens support 30. According to practical experience, since the side coil 60 and the opposing side magnet 50 generate an electromagnetic action during driving, the lens support 30 is attracted to the side of the frame 40 having the driving coil 90. Since the 2 rows of balls 70 act as stressed support points. The balls 70 need not be attached to the opposite corners, and a certain gap margin is provided. When the lens support 30 is driven, the two corner carriers do not contact with the frame 40 to generate friction, so that the balls 70 are not required to be provided.
Preferably, the surface of the guide post 31 that mates with the ball 70 is an arcuate surface. By this arrangement, the friction between the balls 70 and the guide posts 31 can be effectively reduced, so that the lens support body 30 can be ensured to be more smoothly and sensitively moved relative to the frame 40.

Since the anti-shake structure in the present application further includes the plurality of driving magnets 80 and the driving coils 90, the frame 40 can drive the lens support 30 to move in the XY directions under the interaction between the driving magnets 80 and the driving coils 90, thereby playing an optical anti-shake role.
