Description

Rotating mechanism and its camera module, driving device and its electronic equipment

technical field

The invention relates to the technical field of diving, in particular to a rotating mechanism and its camera module, driving device and its electronic equipment.

Background technique

Recently, miniaturized and lightweight camera modules appear in portable terminals such as smart phones, which are popularized due to the development of mobile communication technology. Therefore, at least one camera module is disposed on the body of the portable terminal. Customers' demand for camera module design is increasing day by day. Users not only require the camera module configured on the mobile terminal to have high capacity and high performance, but also need to develop a camera module that meets the digital camera (DSLR) standard. The development of the camera module is in While maintaining high performance and high capacity, it is necessary to meet the development trend of miniaturization and portability.

Among them, the periscope camera module reflects the light beam incident from the vertical direction to the front end of the camera module by placing a reflective prism at the front end of the traditional prism, so that the light beam can be turned from the vertical direction to the vertical direction perpendicular to each other. The horizontal direction, and then reach the photosensitive chip after passing through the lens assembly and color filter, thereby ensuring that the telephoto camera module can meet the long-focus shooting effect while reducing the height of the telephoto camera module. The camera module can be placed horizontally installed in electronic equipment. Therefore, the periscope camera module can meet the requirements of miniaturization of terminal equipment and optical zoom to a large extent. By converting the angle of incident light, the structure of the longer lens can be reasonably changed to reduce the height of the module.

The camera module realizes the optical autofocus function (hereinafter referred to as the AF function, Auto Focus, autofocus) and the optical image stabilization function (hereinafter referred to as the OIS function: Optical Image Stabilization, optical image stabilization) during the shooting process through the motor. The AF function refers to the function of using a motor to move the lens system linearly in the direction of the optical axis to adjust the focus and focus on the subject to produce a clear image at the image sensor (CMOS, CCD, etc.) located at the rear of the lens. The OIS function is a technology that compensates image blur through motor anti-shake control when the lens shakes due to vibration. The image sensor captures the light entering through the lens system and converts it into an image signal.

At the same time, the shooting angle of the camera module is related to the focal length of the optical lens. The smaller the focal length of the optical lens is, the larger the shooting angle is. At this time, the camera module is more capable of shooting nearby scenes. Correspondingly, the optical lens The larger the focal length, the smaller the shooting angle, and the stronger the camera module's ability to shoot distant objects. Because the telephoto lens has a larger focal length, it can shoot at a longer distance, so that it can be shot at a long distance. Therefore, the body of the telephoto lens is usually relatively large, and the large telephoto lens will especially cause The height of the camera module is relatively large. When a camera module with a telephoto lens is arranged on an electronic device, the end face of the telephoto lens will seriously protrude from the surface of the electronic device, which will not only affect the appearance of the electronic device, but also When the electronic device is used, the telephoto lens is easily worn or damaged due to contact with other objects. In addition, it is difficult to mount a suitable motor on the telephoto lens, which may lead to an excessively large overall size.
