Embodiment 1

[0032] like Figure 4 and 6 A sensor drive motor structure is shown, which drives the image sensor 8 to perform anti-shake movement, including magnets 6 that are respectively connected to the image sensor 8 and are arranged on the four sides of the image sensor 8 and outside the two ends of a diagonal line, Coils 4 are arranged on the outer sides of the magnets 6 one by one, and the coils 4 are conductively connected to the external circuit through the annular circuit board 5 .

[0033] It works as follows:

[0034] In this embodiment, the image sensor 8 is driven and connected to the magnet 6. The principle of movement is to use the magnetic field generated by the coil 4 to cause the movement of the magnet 6. The movement of the magnet 6 drives the image sensor 8 to perform anti-shake movement. It is worth noting that, due to the shaking of various postures when performing anti-shake photography, each magnet 6 has a different trajectory under different postures. Therefore, al...

Embodiment 2

[0036] This embodiment is further optimized and limited on the basis of Embodiment 1.

[0037] like Figure 4-6 As shown, the magnets 6 outside the four sides of the image sensor 8 are translation magnets 601, and the magnets 6 outside the two ends of the diagonal of the image sensor 8 are rotation magnets 602. Viewed from the direction of the optical axis, the rotation magnets 602 The side close to the coil 4 has two different left and right stages. The magnet 6 is fixed on the magnet support 7 , and the magnet support 7 is fixedly connected with the image sensor 8 .

[0038] When in use, the present embodiment divides the six magnets 6 into two groups that play different roles respectively, and the rotation magnets 602 distributed at both ends of the diagonal of the image sensor 8 provide torque to make the image sensor 8 rotate, and are distributed in four image sensors 8. The magnet 6 outside the side is used to drive the image sensor 8 for translational movement, and th...

Embodiment 3

[0040] This embodiment provides an anti-shake camera module on the basis of the sensor drive motor structure in any one of the above embodiments, including the sensor drive motor structure in any one of Embodiments 1 and 2, and also includes a sensor drive motor structure for A support assembly that supports the movement of the image sensor 8 is installed and supported, and the support assembly always provides a support base point at the center of gravity of the image sensor 8 .

Abstract

The invention relates to the field of camera devices, and discloses a sensor driving motor structure and a camera module. The sensor driving motor structure drives an image sensor to do anti-shake motion, and the sensor driving motor structure, and comprises magnets which are in transmission connection with the image sensor and are arranged on the four side surfaces of the image sensor and the outer sides of the two ends of a diagonal line; coils are arranged on the outer sides of the magnets in a one-to-one correspondence manner and are conductively connected with an external circuit through an annular circuit board; the camera module further comprises a supporting assembly used for installing and supporting the image sensor to move, and the supporting assembly always provides a supporting base point located at the gravity center of the image sensor. The magnets at different positions play different roles, so that functional modules in the motor are further refined under the condition that few parts are added and the structural simplicity is ensured, a software algorithm for controlling the current of each coil can be simplified, the image sensor can be driven more accurately by using the motor with more precise division of labor, and the anti-shake effect is optimized.

Description

technical field [0001] The present application relates to the field of camera devices, in particular to a sensor driving motor structure and a camera module. Background technique [0002] At present, the OIS optical image stabilization solution for mobile phone image stabilization is realized by VCM motor driving the lens to correct the angle. However, such a solution has long suffered from high power consumption, limited anti-shake effect, large product size, Disadvantages of high unit price. As the scenes of mobile phone photography become more and more abundant, there are more and more demands for anti-shake. That is to say, it is inevitable to improve the shooting effect of smartphones in the scene of sports photography; in addition, terminals Brands have become more and more stringent in controlling the cost of parts and components. The main reason why OIS has not been popularized on some cheap mobile phones is that the cost is too high. Finally, due to the large size...
