Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to an optical lens set, and more particularly to a mutual card-bearing optical lens set. [Prior Art] [0002] In recent years, with the development of multimedia technology, the application of lens modules has become more and more extensive, such as in electronic products such as digital cameras, video cameras, and mobile phones with camera functions. [0003] While people are pursuing miniaturization of digital cameras, camcorders, and mobile phones, it is also desirable to have a clear image of the subject. The image quality of an object depends to a certain extent on the amount of eccentricity of the light between the lenses in the lens module, which depends to a large extent on the way the lens is assembled. [_ S front-type lens group I mode by providing the same inclination angle on the opposite surfaces of adjacent lenses and matching the oil slope and the outer slope surface, so that when the lens is set, the slope is completely abutted in the outer slope, so that two Mirror # mutual card bearing, to ensure that the mirror is coaxially fixed. However, it is limited by the molding process. The inner inclined bevel is usually not precisely formed and closely matched. If the outer bevel is too wide, the stability of the joint between the lenses is reduced and the amount of eccentricity between the lenses is increased. The image quality is degraded. Therefore, the general will narrow the outer slope. However, when the outer bevel is narrowed too narrowly, the stress generated by the close interaction between the inner bevel and the outer bevel during the α-cracking process may cause deformation of the lens, which may also deteriorate the imaging quality of the lens module. [Invention] [0005] There are Rong; 5^ jf, *,, Λ, 'It is necessary to provide a mutual card bearing type 098137880 to optimize the imaging quality Form No. 1010101 0982064973-0 Page 4 of 16 201116878 Optical lens set. [0006] 0008 [0008] [0009] 098137880 a type of mutual card-bearing optical lens set, comprising at least a first lens and a first lens, the first lens and the second lens respectively comprising an optical portion and A non-optical portion surrounding the optical portion. a non-optical portion of the second lens is formed with a first flange on a surface of the first lens, and a non-lighting portion of the first lens is disposed on a surface of the second lens corresponding to the first flange a first elastic portion for splicing with the first flange. The outer diameter of the first flange is not less than the inner diameter of the first elastic portion or the inner diameter of the first flange is not larger than the outer diameter of the first elastic portion. The mutual card-bearing optical lens set of the present invention is provided with a first elastic portion on the first lens, and a corresponding first flange is disposed on the second lens to be sleeved with the elastic portion, even if the first flange The outer diameter is too large (the first flange is in the first elastic portion) or the inner diameter is too small (the first flange is outside the first elastic portion), and the first elastic portion can be elastically deformed to match the first flange. The first lens and the second lens are coaxially connected to each other to stably improve the image quality β, and the elastic deformation of the first elastic portion can also reduce the stress generated by the first flange and the first elastic portion, thereby avoiding the first The lens and the second lens are thus deformed, thereby improving the stability and image quality of the mutual card-bearing optical lens group. [Embodiment] Hereinafter, the present invention will be further described in detail with reference to the accompanying drawings. As shown in FIG. 1 to FIG. 4 , the mutual card-bearing optical lens set 100 of the embodiment of the present invention includes a first lens 1 , a second lens 2 , and a second lens 20 disposed adjacent to each other. a third lens opposite the first lens. The first lens 10, the second lens 20, and the third lens 3 respectively include light 0982064973-0 Form No. Α0101 Page 5 of 16 201116878 The department and the non-optical part surrounding the optics. In the present embodiment, the first lens 10, the second lens 20, and the third lens 30 are all made of plastic. [0011] The non-optical portion of the first lens 10 is provided with a first elastic portion 12 extending from the surface of the non-optical portion of the first lens 1 toward the second lens 2b. Specifically, the first elastic portion 12 includes a plurality of arc-shaped first bosses 121 disposed around the optical portion of the first lens 1A. A first notch 12 3 is formed between each two adjacent first bosses 121. When the first elastic portion 丨 2 is subjected to a radial force, each of the first bosses 121 can be elastically deformed in the radial direction of the first lens 1 。. In the present embodiment, the number of the first boss 121 and the first notch 123 is three. The first elastic portion 2 may be connected to the optical portion of the first lens 1 , or may be spaced apart. In the present embodiment, the first elastic portion 12 is separated from the light of the first lens 1b, and the first spacer groove 125 is formed between the outer edge of the plum portion. The first spacing groove 125 reduces the radial thickness of the first elastic portion 12. Thus, under the same force, the first elastic portion 12 can undergo greater elastic deformation. The first elastic portion 12 abuts the first inner surface 126 of the optical portion of the first lens 1 为 as a circumferential slope which is inclined radially outward from the surface of the first lens 10. In the embodiment, the material of the first elastic portion 12 is plastic. On the surface of the non-optical portion of the second lens 20, a ring-shaped first flange 22 is extended toward the first lens 1''. The outer surface of the first flange 22 is also a circumferential bevel which is inclined radially inward from the surface of the second lens 2G and is equal to or slightly smaller than the corresponding dimension of the first inner surface 26 of the first elastic portion 12. . Thus, when the first elastic portion 12 is sleeved on the first flange 22, the first inner surface 126 will closely fit on the outer surface of the first flange 22 to fix the second lens 20 on the first lens 1 . The second lens 2 () faces the third lens 3 非 098137880 Form No. A0101 Page 6 of 16 0982064973-0 201116878 The second flange 24 of the ring-shaped portion is formed on the surface of the optical portion. The second inner surface 241 of the second flange 24 is a circumferential bevel which is inclined radially outward from the surface of the second lens 20. [0012] [0014] 098137880 The third lens 30 faces the non-optical portion of the second lens 2Q and is formed with a first: elasticity (four) that surrounds the optical portion of the third lens 3G. The outer diameter of the second elastic portion is substantially equal to the inner diameter of the second flange 24, and the second elastic portion 32 is received in the second flange 24. In the present embodiment, the outer diameter of the second elastic portion 32 is also larger than the outer diameter of the first elastic portion 12. Specifically, the second elastic portion 32 includes a plurality of circular bosses 321 disposed around the third mirror (four) wire portion. A second notch 323 is formed between each two adjacent second bosses 321 . When the second elastic portion 32 receives a radial force, each of the second bosses 321 can occur along the radial direction of the third lens 3 . Elastic deformation. In the embodiment, the number of the second bosses 321 and the second notches 323 is three. A second spacing groove 34 is formed between the second elastic portion 32 and the outer edge of the optical portion of the third lens 3〇, so that the second elastic portion 32 can be more elastic under the same force. deformation. The outer surface of the second elastic portion is also a circumferential bevel, which is sufficient. The second inner surface 241 of the second flange 24 is bonded to each other. In this embodiment, the material of the second elastic portion is plastic. Further, a spacer ring 4 is disposed between the first mirror month 10 and the second lens 20, and between the second lens 2 〇 and the third lens 30, respectively. The spacer ring 4 is used to fix the spacing between the first lens 10 and the second lens 20 and between the second lens 2 and the third lens 30, and to avoid direct hard friction between the lenses. When the optical lens set 100 is assembled, the second flange 24 on the second lens 20 is snapped onto the outer surface of the second elastic portion 32 of the third lens 30. At this time, 0982064973-0 Form No. A0101 Page 7 / Total 16 pages 201116878 If the inner diameter of the second flange 24 is too small, the second elastic portion 32 is elastically deformed to adjust the size of the m-shaped portion 32, thereby stably joining the second lens 2〇 with the third mirror. Simple axis. Then, the elastic lens 14 of the first lens 1 is attached to the outer surface of the first flange 22 of the second lens 2G. At this time, if the outer diameter of the first flange 22 is too large, the first elastic portion 12 The elastic deformation occurs so that the first lens 1G can be stably held on the second lens 20 and disposed coaxially with the second lens 2 [ [(8) 15] [0017] It can be understood that the mutual card-bearing optical The lens group 100 is not limited to the embodiment, and may include more lenses, and the combination of the first lens 1 , the second lens 20 and the third lens 30 is used between the lenses. Of course, in another In an embodiment, the mutual card bearing optical lens cylinder 1 may also include only the first lens 1 and the second lens 2, or the value includes the second lens 2 and the third sharp 30. The mutual card-bearing optical lens set 100 is sleeved with the first elastic portion 12 by providing a first elastic portion 12' on the first lens 10 and a corresponding first flange 22 on the second lens 20. Even if the outer diameter of the first flange 22 is too large (the first flange 22 is in the first elastic portion 12) or the inner diameter is too small The first flange portion 22 is outside the first elastic portion 12), and the first elastic portion 12 can be elastically deformed to match the first flange 22 to stably connect the first lens 10 and the second lens 20, and make the first The lens 1 is coaxial with the second lens 20 to improve the image quality. In addition, the elastic deformation of the first elastic portion 12 can also reduce the stress generated by the first flange 22 and the first elastic portion 12, thereby avoiding the first lens 10 and The second lens 20 is thus deformed to improve the stability and image quality of the inter-card-bearing optical lens set 100. Additionally, those skilled in the art can make other variations within the spirit of the invention' 098137880 Form No. A0101 Page 8 of 16 pages 0982064973-0 201116878 [0018] However, all changes made in accordance with the spirit of the present invention are intended to be included in the scope of the present invention.
