Description of the new type: [Technical field to which the new type belongs] This ^^ is about a lens module for a belt-type electronic device, which is a lens module for a portable electronic device with reduced tolerances. & [Previous technology] A has become increasingly popular, and people's requirements for their imaging products f have become higher and higher, and the problem of optical axis deviation in the lens assembly has been one of the important factors affecting the imaging quality. The basic structure of wnH's lens module for portable electronic devices is shown in the third figure, which is the patent No. 9221832 of the Taiwan Intellectual Property Bureau applied by the creator. The special office please reveal the lens of the -type = electronic device. The lens barrel 10 is formed with a hollow channel, and it is set to 2G. Within this hollow channel, multiple lenses are recorded. 31, for converging the signals passed through the two Gan to the image sensor. Among them, the plurality of lenses 30, '31, and the ancient optical axis of the lens barrel io are restricted by the lens barrel 10. However, each lens has a different tolerance size. The reason why Ribe is so bad is that it will lead to larger tolerances during assembly, especially when there are more lenses, which will affect the imaging quality of the lens group. # 光轴 匙 说 There are various types of lens modules for τ-type electronic devices that reduce misalignment tolerances, improve miscellaneous quality, and can generate optical axis deviations. [New content] The difference is: small assembly tolerances, improved imaging quality, and reduced relay technology. I achieve the purpose of this work! This creative provides-a lens module for portable electronic devices, including f2 A lens barrel and a lens group, the lens group includes a plurality of lenses, which makes a lens along its peripheral lens. Two = ', the central axis of the tubular portion coincides with the optical axis of the lens' and its wearing basin ^ = knowing the original lens group-the lens extends the tubular portion 'and holding it by the tubular portion = the method of calculation' its The optical axis is limited by the lens group itself, not by the lens barrel. Therefore, the assembly tolerance is reduced, the optical axis deviation can be reduced, and the imaging quality is improved. [Embodiment] 'This creative electronic device E-face unit is a compact digital camera, or a portable electronic device such as a mobile M264526 phone or PDA with a digital camera. It is shown that the local electronic portable device is based on the following areas: Lai 10, Yi. The upper part of the wire seat is 2 g of a μ® tube shape, and the coin barrel 10, shape; the rectangular structure 'has a built-in image sensor (not shown). The inner diameter of the lens barrel 10 is a hollow cylinder. A hollow passage is formed in the lens barrel 10, and the optical axis of the lens group 30 ′ and the center of the hollow channel 102 are mounted inside the zhong n 02. The light signal of this object It can be collected on the image sensor (not shown) through the lens group 3G. The surface 2 has a transparent cover body 101 for protecting the lens and preventing impurities such as dust from entering the lens 10 and affecting the imaging quality. Mirror j group 30 includes a main lens 301 and a sub lens 302, where the main lens 300 extends to a side-to-side along a peripheral edge thereof, and the central axis of the tubular portion is coincident with the light axis of the main lens. -The secondary mirror 302 is accommodated in the tubular portion 300n of the main lens 300, and the secondary lens 302 is restricted by the g-shaped portion 3011 of the main lens 301 so that its optical axis and the tubular portion 30n The center axis of the main lens and the light axis of the main lens coincide. It can be understood that a plurality of secondary lenses can be installed in the tubular portion 30n of the main lens 301. When assembling, the secondary lens 302 is first accommodated in the tubular portion 3101 of the primary lens 301. Next, the lens group 30 is mounted in the lens barrel 10 so that the optical axis of the lens group 30 and the center axis of the hollow passage are coincident. And the center of the transparent cover 101 of the lens barrel 10 corresponds to the optical axis of the lens group 30. Finally, the assembled mirror is mounted on a semi-leather of the cylindrical base 2G. The base 2 () is fixed to a substrate with a shirt-like sensor (not shown) (not shown). )on. It can be understood that the main lens 301 can be shaped like a tube.卩 3011 Sin is assembled near the top of the lens barrel 10, or the lens portion of the main lens 3101 is close to the bottom of the lens barrel 10, and the secondary lens 3 2 accommodated in the tube portion 301 is close to The top of the lens barrel 10 is assembled. f Referring to the second figure, the second embodiment of the lens module for the portable electronic device of this creation is the same as the first and the first embodiment. The difference is that the main lens 311 of the mirror makeup 31 extends to both sides. The tubular part (not shown), the first tubular part (not shown) on one side is provided with a first auxiliary lens 312 ′ and the second tubular part (not shown) on the other side is provided Second pair of lenses 313. It can be understood that a plurality of secondary lenses can be installed in each tubular portion (not shown) of the main lens 311. 1. According to the characteristics of this creation, the advantages of this creation are as follows: Since the optical axis of each lens is limited by the lens group itself, rather than using components outside the lens group (such as lens barrels, etc.), assembly can be reduced Tolerances, so as to reduce the impact on optical performance, the design of this part has a high degree of integration, a simple structure, and it is not easy to bring in dust. In summary, this creation complies with the requirements for new patents, and a patent application is filed in accordance with the law. However, the above is only a preferred embodiment of creation. For those who are familiar with the skills of this case, equivalent modifications or changes made in reliance on the creative spirit of this case should be included in the scope of patent application below.
