Problems solved by technology

There are two main reasons for the blurred picture caused by existing photography. First, the object moves relative to the lens, resulting in image changes; second, the deflection of the lens optical axis relative to the initial position of the lens optical axis, resulting in image changes.
[0003] The anti-shake camera device provided by the prior art includes: an axis-shifting anti-shake camera device and a translational anti-shake camera device. The disadvantage of the shaft-shifting anti-shake camera device is that the angle of anti-shake compensation is small, and the disadvantage of the translational anti-shake camera device is : The translation anti-shake mechanism mostly adopts the suspension wire structure, the suspension wire structure is complex, the production is extremely difficult, the installation accuracy and positioning accuracy are high, and it is easy to damage

Embodiment 1

[0035] Such as figure 1 figure 2 The shown autofocus device with shake correction structure includes:

[0036] A lens carrier 1 for carrying a lens;

[0037] a frame 5 for supporting the lens carrier 1;

[0038] Base 2 for supporting lens carrier 1 and frame 5;

[0039] A ball support structure for connecting and supporting the lens carrier 1 or / and the frame 5 with the base;

[0040] The front side spring member 3, which is used to provide restoring force in the optical axis direction, is arranged on the lens carrier and extends in the circumferential direction;

[0041] A rear spring member 4 for providing a restoring force in the direction of the optical axis;

[0042] The elastic angle used to provide XY direction recovery;

[0043] The lens carrier 1 is at least partly arranged in the frame 5 and can be displaced in the frame 5 along the optical axis direction; the lens carrier 1 is surrounded by an electromagnetic drive mechanism for driving the lens carrier 1 to ...

Embodiment 2

[0050] Such as Figure 4 Figure 5 As shown, there are four rolling support structures below the frame 5, and the frame 5 is displaced on the X and Y planes through the rolling support structures. The rolling support structures include balls 7 and ball mounting holes 8, and the ball mounting holes 8 are arranged on the same plane as On the ball fixing seat 9 integrally connected with the frame 5, the ball 7 is movably installed in the ball mounting hole 8 and the top of the ball 7 protrudes from the lower end surface of the ball mounting hole 8, and the top of the ball 7 is in contact with the supporting surface of the base 2. The frame 5 is displaced on the X and Y planes through the rolling support structure, and the rolling friction can reduce the friction force, improve the vibration correction effect, and increase the response speed.

[0051] Other structures of this embodiment are consistent with Embodiment 1.

Abstract

The present invention discloses an automatic focusing device with a jitter correction structure. The device comprises a lens carrier which is used for carrying a lens, a frame which is used for supporting the lens carrier, a base which is used for supporting the lens carrier and the frame, ball supporting structures, a front side spring component which is used for providing an optical axis direction restoring force, a rear side spring component which is used for providing an optical axis direction restoring force, and elastic corners which are used for providing XY direction restoration; the lens carrier is at least partially disposed within the frame and can move along a Z axis in the frame; and an electromagnetic driving mechanism for jitter prevention, which is used for driving the frame to move in an XY plane, is arranged around the frame. According to the automatic focusing device with the jitter correction structure of the invention, the influence of jitter on imaging can be greatly decreased; and the lens carrier can move freely on the XY plane through the ball supporting structures so as be combined with the elastic corners of the rear side spring component, and therefore, the stability of jitter correction can be improved.

Description

technical field [0001] The invention relates to an automatic focus device with a shake correction structure, which belongs to the technical field of automatic focus and anti-shake equipment, and is especially applied in the field of miniature image photography that can be used in mobile phones, tablets, computers, automotive electronics and the like. Background technique [0002] Existing portable mobile phones with cameras, supported computers, and touch-control entertainment equipment, when taking pictures with hands, shake due to the shaking of hands, making the pictures taken blurred. The lens in the camera is generally placed on a coil carrier, elastic pieces are respectively arranged on the upper and lower sides of the coil carrier, and coils and magnets are arranged on the outer periphery of the coil carrier. By changing the size of the coil current, the purpose of lifting the coil carrier is achieved. There are two main reasons for blurring the image caused by exist...
