[0002] In recent years, triple-camera and quadruple-camera mobile phones have gradually become standard configurations for high-end models. The popularity of multi-camera mobile phones has also provided a broad development space for the motor industry. Currently, motors with autofocus function are not only applied to the main camera module of mobile phones, but also gradually popularized in the telephoto camera module and the front camera module. In the field of mobile terminals, the future development of autofocus technology mainly focuses on improving the focusing speed, reducing the structural space size, and increasing the stability.

[0003] With the increasing demand of mobile phone users for photography, in addition to the normal photo-taking function, it is also required to be able to take pictures farther and clearer. Currently, the camera modules that can meet the requirements are mainly divided into two categories: one is the upright telephoto camera module, and the other is the periscope telephoto camera module. Limited by their structural size and cost, it is difficult to be widely used in various models. Therefore, on the premise of being able to take pictures farther, making the camera module thinner and lighter is a direction worthy of investment. Summary of the Invention
