Abstract
The utility model relates to a photographic portable lens used for an electronic device, comprising a drawtube and a bracket. The first hollow channel is formed in the drawtube, and a lens unit is embedded in the first hollow channel. The light axis of the lens unit overlaps with the central axis of the first hollow channel, and the light signal of the object to be shot can be assembled to an image sensor through the lens unit. The first thread is arranged on the surface of the inner side of the first hollow channel. The second hollow channel is formed in the bracket, and the second thread is arranged on the surface of the outer side and is merged with the first thread on the surface of the inner side of the drawtube. The drawtube adopts a female thread design, and the outer surface of the drawtube can be always exposed in the process of lens module assembling, so as to enlarge the touchable area between the drawtube and hands or tools and the assembling becomes convenient and the zooming becomes accurate. In addition, after the drawtube is positioned, the drawtube and the bracket are agglutinated by the glue to keep a stable position and reduce the components of the lens module, so as to lead the structure to be simple and the cost further to be reduced.
Description
[technical field]
The utility model is about a kind of portable electron device camera lens capable of taking pictures, especially about a kind of simple in structure, easy to assembly and lower-cost portable electron device camera lens capable of taking pictures.
[background technology]
In the assembling process of the digital camera camera lens module of portable electron device capable of taking pictures (as: mobile phone), need regulate the location to camera lens, with the distance between fixed lens and image sensor, but along with the volume of portable electron device constantly reduces, the volume of the digital-code camera module that it is entrained also constantly reduces, and has just increased the complexity of camera lens module assembling thus.
The basic structure of existing digital camera lens as shown in Figure 2, the outer surface of lens barrel 20 is provided with first screw thread 204, be formed with first hollow channel 206 in it, be embedded with lens combination 202 in this first hollow channel 206, in order to converging to by the light signal of this lens combination 202 on the image sensor, be formed with in the sleeve 22 can ccontaining lens barrel 20 second hollow channel 224, the inner surface of this second hollow channel 224 is provided with second screw thread 222, and be meshed with first screw thread 204 of lens barrel 20 outer surfaces, when assembling this camera lens module, available hand or tool screw in lens barrel 20 in the sleeve 22, in addition, offer fluting 24 in one of sleeve 22 side, 24 inner surfaces of slotting are provided with screw thread, with with the threaded engagement of screw 242, after having assembled lens barrel 20, screw 242 is screwed in the fluting 24, in order to fixed lens barrel 20, the relative position of itself and sleeve 22 is remained unchanged, and then the light signal of guaranteeing object focuses on the image sensor of this module, but for satisfying the focal length of camera lens, so that the light signal scioptics group of object focuses on the image sensor of this digital-code camera module, must regulate lens barrel 20, when lens barrel 20 screw-in sleeves 22 are dark, because the part that exposes reduces, but the contact area that is hand or tool is too small, and causes assembling inconvenience, thus accuracy that also can the image focusing, thereby reduce the image quality of this lens module of digital camera, and use the volume of lens barrel of portable electron device own less.The setting of screw 242, can increase the complexity of whole camera lens module assembling, thereby increase its cost, if it is loosening that this screw 242 takes place, this camera lens module can be subjected to external force and produce and reverse, so make between lens combination 202 and image sensor apart from change, in addition, the location of 242 pairs of lens barrels 20 of screw can make the axis of the axis runout sleeve 22 of lens barrel 20, and then influences the image quality of digital-code camera module.
Therefore, provide a kind of lens locator of simple in structure, easy to assembly and lower-cost portable electron device capable of taking pictures real for necessary.
[summary of the invention]
The purpose of this utility model is to provide a kind of portable electron device camera lens capable of taking pictures, and it is simple in structure, easy to assembly and cost is lower.
In order to realize the purpose of this utility model, the utility model provides a kind of portable electron device camera lens capable of taking pictures, it comprises lens barrel and support, be formed with first hollow channel in this lens barrel, be embedded with a lens combination in this first hollow channel, the optical axis of lens combination overlaps with the central shaft of this first hollow channel, so, but the light signal scioptics group of object and converging on the image sensor, and the inner surface of this first hollow channel is provided with first screw thread, be formed with second hollow channel in this support, its outer surface is provided with second screw thread, and with first threaded engagement of lens barrel inner surface.
Wherein, lens barrel adopts the internal thread design, thereby in the process of this camera lens module of assembling, outside the outer surface of lens barrel is exposed to all the time, thereby but increase hand or tool make things convenient for and install the contact area of lens barrel, also can improve the accuracy of focusing, in addition, after the lens barrel location, and adopt the mode of solid lens barrel of glue glue and support to make its two position that is maintained fixed relation, also can reduce the component count of this camera lens module, make it simple in structure, and then reduce cost.
