Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

The terms "first", "second" and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific sequence or sequence. It should be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the application can be practiced in sequences other than those illustrated or described herein, and that references to "first," "second," etc. distinguish Objects are generally of one type, and the number of objects is not limited. For example, there may be one or more first objects. In addition, "and/or" in the specification and claims means at least one of the connected objects, and the character "/" generally means that the related objects are an "or" relationship.

In the lens-driven OIS method, if the weight of the lens becomes heavy, there is a problem that it is difficult to obtain a sufficient speed to follow hand shake. Tilting during movement will degrade the image quality. Alternatively, it is difficult to correct vibration in the rotation direction in its configuration.

In addition, in the first method of driving the periscope camera module (as shown in FIG. 3 ), two actuators must be used to coordinately drive the two axes in the X direction and the Y direction, which requires complex control. In addition, in the second method (as shown in Figure 2), when driving in the X direction, there will be a problem that the image also moves in the rotation direction (as shown in Figure 5).

In the sensor shift OIS, the image sensor (Image sensor) is connected to many signal lines and power lines, which become the main cause of hindering the movement of the actuator. In the sensor shift OIS for smartphones, the image sensor is supported The sensor and the portion that supplies power to the image sensor are generally bulky, which increases the size of the actuator, and it is also difficult to ensure the degree of freedom in the rotation direction and to achieve correction of the rotation direction. Portable terminals such as smartphones are usually thinner. Therefore, the size of the periscope camera module used in portable terminals has strict requirements in the thickness direction, and Sensor shift OIS is rarely used in portable terminals.

For example, in the sensor shift mounted on a smartphone (Smartphone), the part that supports the sensor and supplies power is larger than the size of the sensor, resulting in a larger projected area of the camera module. In addition, the driving direction is only in the XY direction, and cannot be driven to rotate in the θ direction.

In order to solve at least one of the above problems, an embodiment of the present invention provides a sensor-displacement OIS actuator, which can reduce the projected area of the camera module compared with the prior art, thereby reducing the The overall size enables the sensor-displacement OIS actuator to be conveniently applied to portable terminals. In addition, the OIS actuator of the embodiment of the present invention can achieve high-speed follow-up OIS performance even when the weight of the lens becomes heavy, and can realize correction of the rotation direction. In addition, when the OIS actuator of the embodiment of the present invention is applied to a periscope camera module, the optical system will not become complicated, and the rotation of the image will not occur when the OIS is driven, thereby improving the performance of the camera module. The image quality will not increase the thickness of the camera module or the increase in thickness is very limited.

As shown in Figures 6 and 7, the sensor-displacement OIS actuator provided by the embodiment of the present invention includes:

A substrate 214 on which an image sensor is installed, wherein the image sensor is not shown because it is blocked, and the substrate may specifically be a printed circuit board (Printed Circuit Board, PCB);

The above-mentioned FPC is used for wiring to the image sensor. In the embodiment of the present invention, the spring constant in the X direction is reduced by arranging the first part of the FPC, and the spring constant in the Y and θ directions is reduced by arranging the second part. With the above structure, it is possible to prevent the FPC wired to the image sensor from hindering the sensor shift drive.

In the above structure of the embodiment of the present invention, the spring constant in the X direction is reduced in the first part of the FPC, and the spring constants in the Y direction and θ direction are reduced in the second part of the FPC. Regarding the spring constant of FPC, as shown in Figs. 8 to 9, the spring constant is relatively low in the thickness direction of the FPC, and relatively high in the width direction of the FPC.
