Description
[technical field]
The utility model is about a kind of Zoom optic lens, especially about the Zoom optic lens of a kind of mobile phone with digital camera.
[background technology]
Along with Development of Multimedia Technology, digital camera, video camera more and more are consumers in general's favor, in the time of people's logarithmic code camera, video camera pursuit miniaturization, people wish can take the different object of far and near distance in same position, and the image frame that obtains is clear, the zoom function of digital camera arises at the historic moment thus, and the optical zoom of camera is to realize by the camera lens zoom in the camera.
Generally speaking, the zoom mode of digital camera lens is divided into two kinds of Digital Zoom and optical zooms.Digital Zoom is charge-coupled device (the ChargeCoupled Device that utilizes image sensor, call CCD in the following text) local imaging, promptly in the photo of original shooting, choose an amplification, though digital camera can be by modes such as interpolation in improving image quality to a certain extent, Digital Zoom is to be the zoom of cost to sacrifice resolution and picture quality.The optical zoom of digital camera is to rely on the optical lens structure to realize zoom, promptly pass through the relative position of each eyeglass of change zoom lens, thereby the focal length that changes camera lens amplifies the scenery that is taken or dwindles, and the optical zoom multiple is big more, and it takes just clear more than the distant view thing.Thus, people realize the zoom of camera lens usually by optical zoom.
A kind of existing Zoom optic lens that is used for digital camera, be on the optical axis straight line, to do relative motion by the lens barrel group to realize optical zoom, as announce in No. the 225008th, the TaiWan, China patent on June 11st, 1994 announcement, please refer to Fig. 1, it has disclosed the zoom lens of a digital camera, it comprises an outer sleeve 10, one cylindrical cam sleeve 12, one set collar 13 and a lens barrel group 14, be provided with some straight-line grooves 101 in this outer sleeve 10, in can being sticked in for set protruding key 131 on this set collar 13, make set collar 13 floating locking in outside the cylindrical cam sleeve 12, lens barrel group 14 includes first lens barrel 142 and second lens barrel 144, set collar 13 is provided with spacer 132 and is sticked in locating slot 145 on second lens barrel 144, to limit second rotation of lens, spacer 143 on first lens barrel 142 also is sticked in the locating slot 145, be subjected to the restriction of second lens barrel 144 and can not rotate, first lens barrel 142 and second lens barrel, the 144 outer rollers 15 that are provided with, can make cylindrical cam sleeve 12 on the optical axis straight line, do linear moving by gear 121 effects of slotted hole groove 102 bottom cylindrical cam sleeve 12 outer walls that outer sleeve 10 1 sides are offered, and then make lens barrel group 14 on the optical axis straight line, do relative motion, realize optical zoom function.
This Zoom optic lens moves by the eyeglass of the moving belt index glass head of lens barrel, though can realize the optical zoom of camera, right this Zoom optic lens volume is bigger than normal, when this Zoom optic lens is installed on the fuselage interior of portable electronic equipments such as mobile phone, it is generally installed along the thickness direction of portable electronic equipment fuselage, then the distance of optical zoom is subject to the thickness space of mobile phone at this moment, so that can not realize powerful optical zoom.
[practical utility model content]
In view of above-mentioned condition, be necessary to provide a kind of volume less, be not subjected to the fuselage thickness limits and realize the Zoom optic lens module of high magnification optical zoom.
A kind of Zoom optic lens module, this Zoom optic lens module comprise one first lens barrel and one second lens barrel, are provided with one first lens combination in this first lens barrel, and this first lens combination has a primary optic axis, and this first lens combination can move along the primary optic axis direction; Be provided with a catoptron and at least one second lens combination in this second lens barrel, this catoptron has a reflecting surface, and this second lens combination has one second optical axis, and this second lens combination can move along second optical axis direction; Wherein this first lens barrel is incorporated into a side of second lens barrel, and this catoptron is installed in second lens barrel, and is corresponding with first lens barrel, makes to transmit along second optical axis after the reflecting surface reflection along the light of this primary optic axis transmission.
Compare prior art, Zoom optic lens module of the present utility model is owing to adopted a catoptron, to enter by first lens barrel, reflected certain angle through the light after first lens combination, light is reflexed to second lens combination of Zoom optic lens block length direction, thereby be not subjected to the restriction of its thickness direction when making the optical zoom module zoom, this optical zoom module be loaded on portable electronic equipment such as mobile phone when inner, its zoom also is not subject to the thickness of portable electronic equipment.
[description of drawings]
Fig. 1 is the structural representation of existing Zoom optic lens;
Fig. 2 is the structural representation of the utility model preferred embodiment.
[embodiment]
Please refer to shown in Figure 2ly, the Zoom optic lens module of the utility model preferred embodiment comprises one first lens barrel 20 and one second lens barrel 22.Be provided with one first lens combination 200 (only showing one among the figure) in first lens barrel 20, this first lens combination 200 has a primary optic axis 202.Be provided with a catoptron 220, one second lens combination 222 (only showing one among the figure) and one the 3rd lens combination 224 (only showing one among the figure) in second lens barrel 22, the sidewall of this second lens barrel 22 is provided with a perforate (figure is mark not), this catoptron 220 has a reflecting surface 228, this catoptron 220 can be a prism, also can be a level crossing, this second lens combination 222 has second optical axis 229 that overlaps with the 3rd lens combination 224, and this second lens combination 222 and the 3rd lens combination 224 can move along second optical axis, 229 directions.Wherein this first lens barrel 20 is installed in the perforate of second lens barrel 22, and this catoptron 220 being installed in this second lens barrel 22 at an angle makes and transmit along second optical axis 229 through reflecting surface 228 reflection backs along the light of these primary optic axis 202 transmission.
