Description of the invention: [Technical field of the invention] [0001] The present invention relates to a multi-segment focusing lens module, and more particularly to a portable mobile phone, PDA, etc. Multi-section focus lens module of electronic device" [Prior Art] [0002] With the development of multimedia technology, digital image products such as digital cameras and digital cameras have been widely used, and have a large market demand. In addition, in recent years, mobile phones are rapidly developing in the direction of high performance and multifunction, and mobile multimedia devices combining digital cameras with portable electronic devices such as mobile phones and PDAs are also widely used. In general electronic devices (such as mobile phones, PDAs, etc.), the lens modules of digital cameras are mostly fixed-focus design types, so the zoom function cannot be realized, and the image distance needs to be changed for photographing objects farther away, so the position of the lens needs to be adjusted. [0003] A conventional camera autofocus mechanism, such as the Chinese Patent No. 0234451, No. 6, which is published on March 5, 2003, the focus mechanism is provided with an induction coil at the upper end of the accommodation chamber of the photosensitive element package. The upper end of the photosensitive element is coupled to a magnetic element, the lower end of which is coupled to an elastic element, and the other end of the elastic element is coupled to the bottom of the accommodating chamber. When the camera is in focus, the microprocessor controls the appropriate current to generate a magnetic force that repels the magnetic element to push the photosensitive element to move by the induction coil. By controlling the magnitude of the current to control the amount of movement of the photosensitive element, the autofocus operation is performed. After the focus is completed, the coil is energized, that is, there is no magnetic force, and the photosensitive member returns to the initial position under the action of the elastic member. [0004] Although the camera can realize the focusing function, the mechanism needs to open the induction form number A0101. Page 4/12 pages 1003466702-0 1358605 100 years. December 16th, according to the lane change coil, magnetic components and elasticity The accommodating space of the component increases the volume of the entire lens module, and the structure of the autofocus mechanism of the camera is complicated and inconvenient to assemble. In addition, when the induction coil is de-energized, the generated magnetic force disappears and the elastic component is elongated, and the elasticity is elastic. The component needs to reciprocate for a certain period of time to stabilize, that is, the camera needs to wait for a certain reaction time to take a picture, which makes the camera inconvenient to use. SUMMARY OF THE INVENTION [0005] In view of the above, it is necessary to provide a multi-stage focusing device that is simple in structure, convenient in assembly, and can be operated immediately after the camera is focused. [0006] The multi-segment focus lens module is used for a portable electronic device with a digital camera such as a mobile phone. The multi-segment focus lens module includes a lens group, a rotating member and a support member. The lens group includes a lens group and a lens barrel, and the lens group is disposed in the lens barrel. A reflective element is disposed on the rotating member, and the reflective member includes two reflective surfaces disposed opposite to each other, wherein the two reflective surfaces are inclined with respect to the axis of the lens barrel, wherein a reflective surface faces the lens group of the lens group, and the lens group Fixed to the rotating member; at least two sets of # reflective elements are fixed on the supporting member, each set of reflective elements includes two oppositely disposed reflecting surfaces, and the rotating member is rotatable relative to the supporting member about the axis of the lens barrel, and is disposed on the rotating The two reflective surfaces of the reflective elements on the member respectively face the corresponding reflective surfaces of any of the sets of reflective elements on the support. [0007] Compared with the prior art, the multi-segment focusing lens module only needs a multi-array reflective component, and the rotating component can rotate, so that the light can pass through different reflective components to achieve multi-segment focusing, and the structure is relatively simple. The operation is simple and convenient, and the movement is realized without any intermediate transmission mechanism, and the lens does not need to be moved, so the stability of the rotation is ensured. 094133020 Form No. A0101 Page 5 of 12 1003466702-0 1358605
