[Previous technology] Digital devices are generally used in electronic devices (such as mobile phones, PDAs, etc.), so the zoom function cannot be achieved, and the lens position needs to be adjusted. Most of the camera's optical modules are fixed-focus, and a new zoom distance is required to capture more detailed objects. 34511 force, which reveals-a kind of camera auto-focusing mechanism, __ Gang from L „to 碥 5, another induction coil, Yu, the upper ^ combination-the magnetic element, the lower end of the combination-Duan surnamed Yu Liu Fan 6 W is 7 ^, the bottom of the elastic element is set at the bottom of the room. When the camera auto-focuss over the induction, although the production area is mutually exclusive, it is converted into an appropriate current: the size of the flow, the bribe, === Coffee through the control . Focusing action. After focusing, 1 M270363 stops energizing the coil, starting position. P ',,, and magnetic force are used as the shale, and the photosensitive elements are restored to miscellaneous components. Induction coil, magnetic element and elastic element—The induction magnetic field of the induction coil and the action of the magnetic element make the photosensitive element move up and down to achieve the focusing function. The mechanism needs to be equipped with an induction coil, a magnetic element and an elastic element. The structure of the camera's autofocus mechanism is complex and inconvenient to assemble. 疋 It is necessary to provide a two-stage focusing device with a simple structure and convenient assembly. [New content] 'The purpose of this creation is to provide _view structure Single, two-stage focusing device for convenience. In order to achieve the purpose of this creation, this creation provides a two-stage focusing dress, which includes-lens barrel,-sleeve,-elastic element and —Base, the outer surface of the lens barrel is provided with an external thread 'sleeve_ which is provided with a so-called pattern that matches the pattern of the lens barrel. The lens barrel is screwed to the sleeve by the external thread and the internal thread of the sleeve. : The base is provided with an accommodation space, and the sleeve is accommodated in the accommodation space of the base 'and can be rotated between the first position and the second position of the accommodation space. A depression is formed at the bottom of the sleeve, and the base is provided with a The recess matches the protruding surface, and the sleeve accommodates an empty_rise or descend-distance by the cooperation of the recess and the protruding surface on the base. The two-stage focusing device further includes a retaining body, and the retaining body connecting sleeve Tube and base, and the elastic element is located between the sleeve and the holding body. Compared with the conventional technique, in this work, by rotating the sleeve, the lens barrel is moved up or down by a fixed distance to make the lens barrel and the image sensor Distance difference between devices, elastic action of elastic element The sleeve is simplified at the first focusing position or the first focusing position is fixed, so as to realize the two-stage focusing function of the camera. Also, when assembling, only the sleeve is placed in the accommodation space of the base, and then the base is accommodated in M270363 The two-segment focusing device is easy to assemble without the need for any tools. [Embodiment] As shown in Figures-and-, there are two paragraphs in this creation. The two-stage focusing device 100 can realize two-stage focusing function, that is, two modes of telephoto and close-up. The two-stage focusing device hall includes a lens barrel 10, -holding body 20, -elastic element 30, -set The barrel 40 and a base 50, the lens barrel ι and the sleeve 40 are concentric ring structure. The lens barrel 10 contains a lens group (not shown), and the positional relationship of the lens combination of the lens group depends on the characteristics of the lens It is determined in advance that the outer surface of the lens barrel 10 is engraved with external threads 12. The holding body 20 is composed of a first-longitudinal wall 22, a second vertical wall 24, and a top surface 26, so that the fixing body 20 has a substantially "n" shape. The first longitudinal slit 22 and the second longitudinal wall 24 are provided with a rectangular opening 28, and a circular paste opening 29 is also provided on the top surface 26. The diameter of the circular opening 29 is slightly larger than the diameter of the lens barrel 1G, but smaller than the sleeve. The outer diameter of the tube milk allows the lens barrel material to extend into the accommodating space of the holding body 20. "The inner wall of the sleeve 40 has an inner view 42 that matches the Gu 1G external thread 12, and the lens barrel is screw-connected to the sleeve milk 4 and the sleeve 4g at the end of the sleeve through the external thread U and the closure 42. The number of recessed fe44, step 46, the number of recessed 44 and step # can be greater than or equal to the random reading 30. The elastic sheet design is used, which can expand and contract within a certain range. The elastic element 1 is larger than the inner diameter and outer diameter of the sleeve 40. The outer diameter of the sleeve 40 is less than or equal to that. Carved Fanniu 30 can be placed on the sleeve 40. / Base 5G-roughly square body%, with the center of the body% as the center to form a circle M270363 The four corners of the main body 56 are bifurcated to form a foot 52 with the same structure upward. The two sides of the main body 56 are horizontally extended to form a protruding portion 55. The hard-to-get-out portion 55 can be a rectangular opening 28 of the temple body 20. Phase engagement, the space surrounded by the four feet 52 can just accommodate the sleeve milk. The circular groove 58 is provided on the circumference at equal intervals with protruding surfaces M that fit into the recesses of the sleeve 4G, With the protruding surface 54, a distance difference is generated between the sleeve 4G and the base 5Q, the height of the protruding surface% and the depth of the depression 44 «, the protruding surface The height of 54 is determined by the two-stage focusing characteristics of the field tube ω phobia lens group. When assembling, 'the lens barrel 10 is first screwed into the sleeve 40, and the internal thread 12, the external thread 42 and the sleeve 40 are screwed. Then, in order to prevent the relative position of Lai 1G butterfly 40 from changing, water (also other miscellaneous), 1G butterfly 4G, high paste 4G depression correction and 5G base "54 fit; finally, the elastic element 30 is placed on the sleeve 40, the holding body 20 passes through the lens barrel 10, and the lower pressure member 30 is pushed down, and the first-longitudinal wall 22 and the second longitudinal wall are lifted. Round, the side editor clips the protruding part into the rectangular opening 28, and the group _ elastic element ㈣ is in a compressed state. This embodiment ___________________________, which is the second focus state. When shooting, if you want to achieve the second focus state, rotate the sleeve 40 to make the depression 44 and the base 54 (the protruding surface 54_, which is called the elasticity of the flexible element as the next step 46), and the image of the mirror The distance between the detectors (not shown) changes, so as to achieve the second kind of confrontation energy. When you need to return to the initial county «, rotate in the opposite direction: ... 田 ... 一 —- 突": Tight M270363 Back to the initial focus state. In this two-stage focusing device 100, the sleeve 40 is rotated, and the sleeve 40 drives the lens barrel 10 to rise or fall by a fixed distance so as to create a distance difference and elastic element between the lens barrel 10 and the image sensor. The elastic effect of 30 fixes the relative position of the recess 44 and the protruding surface 54 of the sleeve 40 when the two focusing devices are used to achieve the two-stage focusing function of the camera. Table τ, as mentioned above, this creation complies with the new patent requirements, 爰Filed a patent application in accordance with the law. However, the above is only a preferred embodiment of this mine. For example, those who are familiar with the creation, modify or change the essence of the creation according to this creation, should be included in the town's material.
