Description

Camera lens module

Technical field

The present invention is relevant with lens construction, in more detail refers to a kind of camera lens module.

Background technology

In recent years, along with the progress of image science and technology, such as device for image such as camera, video camera, microscope or scanners, for being convenient for people to carry and use, and tend to gradually miniaturization and lightweight, this will so that the volume of the used camera lens module of these device for image also therefore significantly dwindled.

For effectively reaching the effect of miniaturization, see also Fig. 1, the camera lens module 2 of existing device for image can be taken in its eyeglass group frame 50 and be integrated in the fast door frame 60, use the volume that reduces these camera lens module 2 integral body, and then make the purpose that reaches this camera lens module of miniaturization, use the portability that increases this device for image.

Yet, above-mentioned design is not only so that 62 at the eyeglass 71 in this camera lens module 1 and shutter are separated with the distance of this eyeglass group frame 50 housing thickness, and so that the increase of the spacing of eyeglass 71 and shutter 62, cause the thickness of this eyeglass 71 lifting just can reach better optical performance, and then can't effectively reach the purpose of miniaturization.

In addition, the external diameter size of this eyeglass 71 also is subject to the restriction of this eyeglass group frame 50 inner spaces, and can't select the larger lens of external diameter, and so that the optical performance of this camera lens module 2 also can't effectively promote, be with, comprehensively the above can be learnt, the design of existing camera lens module 2 is not discriminated perfect yet, and the part that still haves much room for improvement.

Summary of the invention

The technical problem to be solved in the present invention is, can't realize the defective of miniaturization for camera lens module of the prior art, and a kind of camera lens module is provided, and can effectively reach the effect of miniaturization, and can reduce the restriction that the eyeglass external diameter is selected.

The present invention is that the technical scheme that its technical matters of solution adopts is, a kind of camera lens module is provided, and includes fast door frame, eyeglass group frame and plural pieces eyeglass, and wherein, this shutter has set up shutter; This eyeglass group frame has the first end towards this shutter, and has accommodation space in this eyeglass group frame; These eyeglasses sequentially are arranged on this eyeglass group frame along the optical axis of this camera lens module; Wherein a slice is located on this first end of this shutter, and between this eyeglass group's frame and this fast door frame; Other eyeglass then is located in this accommodation space.

By this, just can see through the structural design of above-mentioned camera lens module, reach the effect of miniaturization, and can reduce the restriction that the eyeglass external diameter is selected, and then can promote the optical performance of this camera lens module.

Embodiment

For being illustrated more clearly in the present invention, hereby lifting preferred embodiment and cooperate accompanying drawing to be described in detail as follows.

See also Fig. 2 and Fig. 3, the camera lens module 1 of preferred embodiment of the present invention comprises lens barrel 10, fast door frame 20, eyeglass group frame 30 and three eyeglasses 41～43.Wherein:

Be formed with three guide rails 12 on the inner tube wall of this lens barrel 10, and these guide rails 12 are formed with respectively opening 14 in an end of this lens barrel 10.

This fast door frame 20 is incorporated in this lens barrel 10.Whether this fast door frame 20 is provided with shutter 22, allow light pass through this camera lens module 1 in order to control.

Have accommodation space 32 in this eyeglass group frame 30, and have three protuberances 34 that distribute to arrange on the periphery wall of this eyeglass group frame 30, respectively this protuberance 34 enters by the opening 14 of correspondence and is positioned at respectively this guide rail 12, and this eyeglass group frame 30 is arranged in this lens barrel 10.In addition, continuous consult Fig. 4, the first end 36 that this eyeglass group frame 30 has towards this shutter 22, and have the some glue groove 361 of four scattering devices on this first end 36.

These eyeglasses 41～43 sequentially are arranged on this eyeglass group frame 30 along the optical axis of this camera lens module 1, and are respectively the first eyeglass 41, the second eyeglass 42 and prismatic glasses 43.Wherein, this first eyeglass 41 stands on this first end 36 of this eyeglass group frame 30 through suppressing the tool group, and be connected with these glue grooves 361, and utilize the mode of some glue in these glue grooves 361, to be installed with viscose, and make this first eyeglass 41 glutinous being located on this first end 36.In addition, 43 of this second eyeglass 42 and this prismatic glasseses sequentially storehouse be fixedly arranged in the accommodation space 32 of this eyeglass group frame 30.

By this, as seen from Figure 5, see through this first eyeglass 41 is fixedly installed on this first end 36 of this lens barrel 30, the eyeglass quantity of these accommodation space 32 carryings is reduced, and so that eyeglass group frame 30 can reduce outside its volume in design, more can be with the hypotelorism of 22 at this first eyeglass 41 and this shutter, and so that this first eyeglass 41 need not increase the purpose that thickness can reach high optical performance, and above-mentioned design also can be so that this first eyeglass 41 can not be subject to the restriction of this eyeglass group frame 30 sizes, and can select the eyeglass of larger external diameter.Therefore, seeing through above-mentioned design not only can be so that this camera lens module 1 can reduce volume effectively, and reaches outside the effect of miniaturization, also possesses the effect that high optical performance is arranged simultaneously.

And should be noted that, the present invention is not limited the method that eyeglass is fixed on the eyeglass group frame with above-mentioned gluing, also can utilize such as projection and engage fixing structural design or other feasible fixed form with groove, and so long as eyeglass is fixedly installed between this eyeglass group's frame and this fast door frame, reach the purpose person that the reduction volume reaches miniaturization, no matter be to use which kind of design, also belong to the other form of implementation of the present invention.
