Detailed ways

In order to make the purpose, technical solutions, and advantages of the application more clear, the application will be further described in detail below with reference to the accompanying drawings.

When using terminal products such as mobile phones to take pictures, users often need to zoom in and shoot images due to the shooting distance or composition design. However, as the magnification increases, pure digital zoom will severely sacrifice image resolution. More and more mobile phone camera modules have added an optical zoom function, which optically ensures that images with multiple fixed focal lengths can be collected. Combined with digital zoom algorithms, it can cover a wider zoom range while maintaining image analysis force. At present, the most widely used optical zoom hardware solution on mobile phones is a dual fixed-focus module structure composed of a standard focal length main camera combined with a long focal length sub-camera, but this solution has poor scalability. When hardware is required to collect more For images at focal lengths, more camera positions, as well as corresponding sensors and drive circuits, must be reserved on the mobile phone housing, resulting in increased costs. Based on this, the embodiments of the present application provide a camera module, which can realize the optical zoom function on the basis of one camera, so the cost is low, and it will not be integrated into small terminal products such as mobile phones. Affect its appearance quality.

In the embodiment of the present application, the camera module may further include a light turning element 30, which is located at one side of the light entrance side 11, and is used to turn the light entering the camera module into the fixed focus lens group. Specifically, the light can enter the camera module along the light entrance axis of the camera module, and after being turned by the light turning element, it enters the light entrance side of the fixed focus lens group along the optical axis of the fixed focus lens group. In the specific design, the optical axis of the camera module can be perpendicular to the optical axis of the fixed focus lens group, so that the camera module becomes a module with a periscope structure, which can be applied to electronic equipment with ultra-thin design To expand its application scenarios. It should be noted that the light incident along the light entrance axis can be understood as the light entering the camera module with the light entrance axis as the center. The light and the light entrance axis can be parallel or have a certain angle with the light entrance axis. ; Similarly, the light incident along the optical axis of the fixed-focus lens group can be understood as the light entering the light side with the optical axis of the fixed-focus lens group as the center, and the light can be parallel to the optical axis of the fixed-focus lens group.

As shown in FIG. 5, the light turning element 30 may further include a first rotating shaft 34 and a second rotating shaft 35, wherein the extending direction of the first rotating shaft 34 is parallel to the light entering axis (that is, the z-axis direction), and the extending direction of the second rotating shaft 35 The directions are respectively perpendicular to the light-in axis and the optical axis of the fixed-focus lens group 10 (ie, the y-axis direction), the mounting portion 32 is rotatably connected to the base 31 through the first rotating shaft 34, and the light turning portion 33 is connected to the mounting portion 32 through the second rotating shaft 35. Rotate the connection. In this way, the mounting portion 32 and the light turning portion 33 mounted on it can be rotated around the z-axis direction through the first rotating shaft 34 to compensate for the deviation of the light in the y-axis direction caused by jitter, so that the camera module realizes the y-axis Optical image stabilization in the direction; the light steering portion 32 can be rotated around the y-axis direction through the second rotating shaft 35 to compensate for the deviation of the light in the z-axis direction caused by jitter, so that the camera module realizes the optical in the z-axis direction Anti-shake.

It can be understood that in other embodiments of the present application, the extension direction of the first rotation axis can also be set to be perpendicular to the optical axis of the light-in axis and the optical axis of the fixed focus lens group (that is, the y-axis direction), and the second rotation axis The extension direction is set to be parallel to the light-in axis (that is, the z-axis direction), so that the optical image stabilization of the camera module in the z-axis direction and the y-axis direction can also be achieved, which will not be repeated here.

Referring to FIGS. 6, 7 and 8, the camera module further includes a zoom device 40, which includes a first zoom assembly 50, and the first zoom assembly 50 may include a zoom lens group 51 and a driving component 52, specifically When set up, the zoom device 40 is provided with a first working position 41 and a second working position 42, and the driving component 52 is connected to the zoom lens group 51 to drive the zoom lens group 41 to move from the first working position 41 to the second working position 42, or drive the zoom lens group 51 to move from the second working position 42 to the first working position 41, so as to realize the switching of the zoom lens group 51 between the first working position 41 and the second working position 42.

Among them, M is the zoom factor that can be achieved when the A-times fixed-focus lens group 10 and the B-times zoom lens group 51 are used in combination. The values of M and A can be determined at the beginning of the design according to the actual use requirements of the camera module.
