Description
Technical Field
The utility model relates to an anti-shake cloud platform field especially relates to a folding circuit board structure.
Background
In recent years, small-sized mobile devices with shooting functions are quite popular, and the application range is also continuously expanded, including aerial photography, motion cameras and automobile data recorders. The device comprises at least one Compact camera module (Compact camera module). Therefore, the market of the module is huge, and the growth is steadily promoted.
When taking pictures and films, the pictures and films taken by the device are likely to be blurred or shaken by external vibration, which affects the quality of the pictures and films. This problem is exacerbated when the vibrations are relatively intense, or in low light conditions.
In order to solve the above problems, many small-sized anti-shake technologies have appeared on the market. Among them, the effect of improving the picture quality is most excellent by mechanically compensating for the blurring and shaking of the image due to the vibration. The mechanical method can be to translate a group of lenses through an anti-shake actuator (refer to patent documents CN104204934A, US20140333784A1) or rotate a group of lenses and an image sensor (refer to patent documents CN102934021B, US9229244B2) to achieve an anti-shake effect. The anti-shake effect of the rotary mechanical method of the second kind is generally better than that of the first translation mechanical method, therefore the utility model provides a small-size circuit board design is also mainly to the rotary method.
Since the rotary anti-shake actuator needs to move the image sensor during the anti-shake process, the circuit board connected to the image sensor needs to be connected to other fixed structures through an elastic structure capable of conducting electricity, so that other external components (such as a single chip microcomputer and a power supply component on a main board of a small mobile device) can be electrically connected and communicated with the image sensor, and can capture images and provide power.
The elastic structures are all usually composed of Flexible Printed circuit boards (Flexible Printed circuits), have good multi-axis elasticity and drop resistance, can resist impact and acceleration force when falling, and do not influence the multi-axis movement of the movable structure in the actuator in the anti-shake process.
For rotary anti-shake actuators, existing circuit board designs can be divided into two categories. The first category (patent documents: CN107315302A, CN208399865U) is not folded, and the elastically deformable portion of the circuit board connecting the movable and stationary portions is on a plane, and the multi-axis rotational freedom is achieved by special circuit board design. The technology has the advantages of small required space, simple production process and low cost.
The second category (references: CN106338873B, CN109752863A) achieves multiaxial freedom by up to three crimps. The advantage of this design is that a maximum of three-axis rotational degrees of freedom can be provided.
In the first prior art (refer to patent documents: CN107315302A, CN208399865U), although the multi-axis rotational degree of freedom can be provided, the spring coefficient in the optical axis rotational direction (rolling) is usually much larger than that of the other two axes (yaw and pitch), which results in excessive power consumption in the rolling direction, difficulty in realizing rolling anti-shake, or reduction in battery endurance.
In the second prior art (refer to patent documents: CN106338873B, CN109752863A), in order for the elastic structure to have good multiaxial elasticity and drop resistance, the flexible circuit board composing the elastic structure often needs to be curled or needs to have a longer shape. Such a design requires a large space for the anti-shake actuator, which hinders the miniaturization of the anti-shake actuator. In addition, the coefficient of the multi-axis rotating spring of the design is generally higher, so the average anti-shake power consumption is higher; and it is difficult to make the spring coefficients of each axis very close, resulting in large power consumption difference in different directions, and power consumption in some directions will be higher than that in other directions.
