In the camera lens module of said structure, its parts are more relatively, and camera lens 1 ' axial location by spring 4 ' realize because each spring 4 ' unbalance stress, make camera lens 1 ' generations inclination easily, and influence image quality; Camera lens 1 ' with pedestal 3 ' connected mode be adopt projection 11 ' with groove 31 ' cooperate, owing to be exact instrument, so it is high that each planar light slippery that cooperates requires, and in the actual process, be difficult for processing desirable smooth flat, therefore can influence camera lens 1 ' flatness and stationarity, be the factor that influences image quality equally; In addition, the pedestal 3 of camera lens 1 ' relatively ' axial linear movement make this camera lens module occupy more space, be unfavorable for realizing short and smallization of camera lens module.
In view of above shortcoming, be necessary to provide moving accurately steadily of a kind of simple in structure, camera lens, and make the camera lens module occupy the two-part focusing structure in less space.
[utility model content]
It is a kind of simple in structure, mobile accurately steady that the purpose of this utility model is to provide, and make the camera lens module occupy the two-part focusing structure of the two-part focusing structure in less space.
The utility model two-part focusing structure is used for the portable electron device of band digital camera such as mobile phone, is installed in the housing, and it comprises a lens group, one first reflector group, one second reflector group, a push rod and an image sensor.This lens group comprises a lens combination, and it is installed on the housing; This first reflector group is positioned at this housing, and it comprises two-mirror, and the reflecting surface of this two-mirror is opposing; This second reflector group comprises two-mirror, and the reflecting surface of this two-mirror is relative, and this second reflector group is fixed in the housing; This pusher section stretches out case of electronic device, can be along moving back and forth with the uneven direction of the axis of lens combination, this image sensor is installed in the housing, towards this lens group, and this lens group, first reflector group and second reflector group all are positioned at the same side of this image sensor.This first reflector group is connected with this push rod, it can move back and forth along with push rod one arises between a primary importance and the second place, it is when primary importance, light is direct directive image sensor after lens combination, its when the second place, light through after the lens combination again via the reflection of this two-mirror group after directive image sensor again.
Compare prior art, the utility model two-part focusing structure only needs a two-mirror group and a push rod, can realize the two-part focusing by this push rod of push-and-pull, and its structure is comparatively simple, and operation is also very simple, convenient; The utility model is directly moved by mobile drive one reflector group of push rod and realizes the two-part focusing, does not have any intermediate transmission mechanism, and camera lens also need not to move, so guaranteed the stationarity that it moves; In addition, this creation utilizes the reflection between the catoptron to change over the image distance that looks like, and the distance between need not to change between lens group and image sensor, thereby saved the space, help electronic installations such as mobile phone and PDA towards small-sized development, and this is just complying with the existing market demand.

[embodiment]
The utility model two-part focusing structure is applicable to the portable electron device of band digital cameras such as mobile phone and PDA.
See also Fig. 2 and Fig. 3, the utility model two-part focusing structure comprises a lens group 10, a framework 12, one first reflector group (not indicating), one second reflector group (not indicating), a push rod 19 and an image sensor 20.
This lens group 10 comprises a lens combination 100 and a lens barrel 102, and this lens barrel 102 is a hollow circular cylinder, and lens combination 100 places in the lens barrel 102.
This framework 12 is the rectangular framework of sealing of hollow in one, and its two adjacent surface is opened first hole 123 and second hole 125 respectively, and this lens group 10 is placed in first hole 123 and is fixed on the framework 12, and its part is positioned at framework 12, and another part stretches out framework 12; The inside surface of the framework 12 relative with second hole 125 is provided with two supports 121, and it is used to support this second reflector group.
This push rod 19 comprises a press section 191 and a support sector 192, and this press section 191 is discs, and this support sector 192 is right cylinders, fixedlys connected with this support sector 192 in this press section 191, and its axis is on same straight line.This support sector 192 is placed in second hole 125, and it can move back and forth along the axis in second hole 125.
This first reflector group comprises one first catoptron 14 and one the 3rd catoptron 16, and this second reflector group comprises one second catoptron 15 and one the 4th catoptron 17.First reflector group is arranged at the end away from press section 191 of the support sector 192 of push rod 19, it is fixed by glue, first reflector group can move back and forth between a primary importance and the second place along with moving of push rod 19 thus, in addition, the reflecting surface of first catoptron 14 of this first reflector group is towards this lens group 10, the reflecting surface of the 3rd catoptron 16 and the 14 opposing settings of first catoptron, even its non-reflecting surface is relative, the angle of its reflecting surface is 90 °, and the reflecting surface of this first catoptron 14 and the 3rd catoptron 16 all with 45 ° of the axis angles of lens barrel 102.The two-mirror of second reflector group is individually fixed in the end of this two support 121, and its reflecting surface is relative, and all face is relative with the reflecting surface of the first reflector group catoptron, and the reflecting surface that makes this two-mirror all with 45 ° of the axis angles of lens barrel 102.
When taking remote photo, this first reflector group is positioned at its primary importance with this push rod 19, between first reflector group and second reflector group distance farthest, lens combination 100 backs of light by lens group 10 directly arrive image sensor 20 and imagings, image distance is less at this moment; When taking close up photos, push the press section 191 of push rod 19, push rod 19 is pushed, this first reflector group arrives its second place with this push rod 19, nearest between first reflector group and second reflector group, light is by behind the lens of lens group 10, and through arriving image sensor 20 and imaging after the reflection of first reflector group and second reflector group, this moment, image distance was bigger again.And the location of above two positions can be provided with two blocks and get final product on push rod 19.Realized the two-part focusing by above process.
