The ball 103 partially protrudes from the receiving groove 1〇2. A sliding groove 175 is formed on the surface of the projection 郜 17 4 opposite to the fixing member 101 to engage with the ball 1 〇 3 . The center of the arc-shaped chute 17 5 is located on the central axis of the outer sleeve 17 〇. When the outer sleeve 17 turns, causing the balls 1〇3 to move within the chute 175 so that the outer sleeve 17〇 moves, its central axis does not move. The number of the protrusions 174 and the fixing members 1〇1 may be one or plural. In order to prevent the optical axis from shifting during the zooming of the camera module 1 , it is not limited to the manner in which the balls 1 〇 3 are disposed between the fixing member 101 and the protruding portion 17 4 , and may be applied to the fixing member 1 . A slider and a sliding groove are disposed between the protruding portion 174 and the protruding portion 174 so that the slider is received in the sliding slot and slides along the sliding slot. 098124273 Form No. A0101 Page 10 / Total 22 Page 0982041440-0 201104285 [0022] [0022] The camera module 1 provided in this embodiment can control the focus lens module 130 to focus, and by The zoom drive module 18 of the zoom camera module 14 is controlled so that the length of the driving rod body 1822 between the driver 181 and the mating rod body 1821 becomes smaller, and the outer sleeve 170 is rotated by the driving rod 182. The guide post 154 of the sleeve 150 is pressed against the first baffle 191 and moves the guide post 154 along the guide hole 171, so that the inner sleeve 150 and the zoom element group 160 are away from the focus lens module along the optical axis. The distance between the zooming optical element group 160 and the focusing optical element group 136 in the group 130 direction movement becomes large, and the focal length of the camera module 100 changes. [0023] The zoom driving device 180 of the zoom camera module 14 is controlled such that the length of the driving rod body 1822 between the driver 181 and the mating rod tortoise 1821 is increased, and the outer sleeve 170 is rotated by the tilting lever 82. The guide post 154 of the inner sleeve 15 is pressed against the second baffle 192, and the guide post 154 is moved along the guide hole 171, so that the inner sleeve 150 and the zoom optical element group 16 are along the optical axis. Moving closer to the focus lens module 13 , the distance between the zoom optical element group 160 and the focusing optical element group 136 becomes smaller, and the focal length of the camera module 100 also changes. Therefore, the camera module 10 can be made to have a zoom function during the imaging process. The second embodiment of the present invention provides a camera module 200 having a structure similar to that of the camera module 100 provided in the first embodiment. The difference is that the stopper 290 is fixed to the circuit board 210. The plate defines an elongated hole defining a hole 291 extending along a central axis of the outer sleeve 270 in the stopper 290. The guide post 254 is received in the defining hole 291 from one end of the outer sleeve 270. When the zoom driving device 280 drives the outer sleeve 270 to rotate, the hole wall 2911 defining the hole 291 abuts against the guide post 254 such that its 098124273 form number Α0101 page 11 / total 22 page 0982041440-0 201104285 along the guide hole 271 The movement is such that the inner sleeve 250 moves in the direction of the central axis of the outer sleeve 270. Preferably, the length of the defining hole 291 in a direction parallel to the central axis of the outer sleeve 270 is greater than the distance of the guiding hole 271 away from the circuit board 210-end to the circuit board 21A. [0024] The camera module provided by the technical solution only needs to install the zoom lens module on the existing camera module with the focusing function, so that the camera module has the functions of focusing and zooming at the same time. Compared with the camera module with zoom and focus function in the prior art, the camera module provided by the technical solution has the characteristics of simple structure and small space. Therefore, the camera module provided by the technical solution can be widely applied. .. ί.. used in portable electronic devices such as mobile phones, laptops and the like. [0025] In summary, the present invention has indeed met the requirements of the invention patent, and the patent application is filed according to law. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application of the present invention. Equivalent modifications or variations made by persons skilled in the art in light of the present invention are intended to be included within the scope of the following claims.
