In addition, in recent years, mobile phones have also been rapidly developing in the direction of high-sexual t* and eve functions. Digital cameras and mobile phones, PDAs, etc., are also widely used. Therefore, the needs of digital camera lens modules are also It is getting bigger and bigger. In order to achieve better shooting results, the lens will be set in the lens module - red 2 slices to filter out infrared noise. The infrared cut-off film is located at the end of the lens barrel of the lens module, which is assembled & After the completion of the method, the method between the infrared cut-off piece and the lens of the lens module is provided, and the method includes direct transfer and touch. The transfer mode is f-connected = Lai, the junction of the .X outer cut-off piece is glued on the coffee place. The disadvantage of this method is that it is difficult to control the movement. If the glue is too expensive, it will easily contaminate the infrared cut-off piece. If the glue is too small, it will not be strong. Causes infrared interception and loss. The hot-melt square wire is placed on the top of the lens barrel. The thermoplastic deformation of the tube is used to cover and fix the infrared cut-off piece. However, the structure of the lens barrel is complexed and it is difficult to make it er, and if it is too _ cannot. In addition, it is necessary to increase the heat-melting step during assembly. [Invention] It is necessary to provide Qianjie, and it is necessary to avoid the establishment of a contaminated holding device. It is also necessary to provide a fixed type of infrared cut-off piece that is not easy to be contaminated. The lens module is actually 1^1: the holding device 'includes the body' body as the ring body' body-side side to the same side Γΐ 复The protrusions are provided with at least two diametrically-centered body-centered bending flaps and at least two outer-side bending-out flaps facing the holding device. The adjacent-into-head module includes a lens barrel, a lens group, a holding device, and an infrared cut-off piece. At least two mounting slots are defined at the end; the lens is assembled in a mirror; the holding device body has an annular body, and one side of the body extends a plurality of protrusions in the same direction, and the 5 protrusions are provided with at least two sides The external fixation of the holding device is fixed: the inner flap of the body center bend and the at least two inner groove of the folding piece are inserted into the money groove, and the person is inclined to the An Lai. The external phase is better than the conventional technique in the lens barrel, so that the infrared load-stopping piece is directly fixed by the structure on the infrared cut-off piece, and the outer thief is not used. Ride the lens module [Embodiment] (4) The fixing of the stop piece is convenient and fast, and it is not easy to be polluted. 20, ^ ΐ: 0 Figure ^ Mounting Figure 6, the preferred embodiment of the inventive lens module includes - the lens barrel u pays us 60 and an infrared cut-off piece 8 〇. u ^ * The other end of the brother tube 20 is provided with two oppositely disposed mounting slots 206. The lens group milk is disposed in the lens barrel 2, which includes a plurality of lenses. The device 6A includes a body 601' body 601 having an annular shape, i.e., a center, and the outer diameter of the body 601 is equivalent to the inner diameter of the lens barrel 20. The body ί# has the same protrusion 603 extending in the same direction, and the four protrusions 603 extend along the axis direction of the body 601 of the body. The top portion 1 of the oppositely disposed protrusion 603 has an inner flap 604 which is provided with a second outer flap 606 along the radial direction of the body 6〇1 toward the top of the center bend 603 of the body 6〇1. Sheet 606 is folded along the outer side of 601. The inner flap 604 and the outer flap _ edge holding device 6 外 two outer flaps _ the insertion groove 2 〇 6 of the insertion lens barrel 20 are fixed to the lens barrel 2 。. The holding device 6 is made of a plastic material. The infrared cut-off piece 80 is a circular piece, and the outer diameter thereof is slightly larger than the hole column of the opening 6〇2 of the holding device 6〇, and is not larger than one of the holding device 6〇. 6〇3 inside to the center of the body 6〇1 twice the distance. Referring to the fourth figure, the infrared cut-off piece 80 is disposed on the holding device 60, which is fixed by the inner flaps 6〇4 of the holding device 60. When the mirror/贞 module is used, the mirror plate 40 is first loaded into the lens barrel 20 and fixed, and the lens group 40 is close to the light-passing hole 2〇4 end of the lens barrel 20; the infrared cut-off piece 8 is snapped into On the holding device 6 ,, the inner flap 6 〇 4 of the holding device 60 presses and fixes the infrared cut-off piece 8 ;; finally, the holding device 60 and the infrared cut-off 8Q __ pick-up lens barrel 2 〇), the rotating device 6Q is pressed into the lens barrel 2〇 by the lens barrel and the holding, and the elastic of the protrusion 6〇3 of 60 is placed, and the flap 6 of the holding device 6〇 is slid into the mounting groove 206 of the lens barrel 20, thereby The holding device 6 is fixed in the lens barrel 2, and the infrared wearing 1362.514: the trial piece 80 is also fixed at the same time. # The holding device can be made of a metal material, and the flipping device (five) ′ includes a η-square 2 opening at the center of the body 6Q1'. The main body rainbow-side edge® peripheral edge uniformly extends in the same direction with two convex piece and two convex piece coffee piece (6). Two== set f holding device 6 (r body of the body 60Γ extends in the axial direction. Assembly side , so that it runs 6G, _ convex (four), and then presses and fixes, and the tab 6〇r is bent to the outside of the holding device 6〇'. The convexity of the holding device 60, 60 The 603 and the tabs 605'w are not limited to the four settings: the second and the tabs 605'6°r may also be uneven and an outer fold J. One or three ' and one of the protrusions 603 is simultaneously provided on an inner flap Invented in accordance with the requirements of the invention patent, Mai filed a patent application.
