First embodiment
When in order to solve to realize focusing using traditional camera module in the prior art, that there are FOV and optical axis is unstable,
Phenomena such as magnetic interference, causes the problem of focus effects difference.It is shown in Figure 3 the present embodiment provides a kind of camera module,
The camera module 30 includes flexible circuit board (Flexible Printed Circuit, FPC) 301, imaging sensor
(image Sensor) 302, camera lens carrier 30 as one kind 3, camera lens Lens 304, wherein image sensing 302 is arranged on FPC soft board 301
Side, camera lens carrier 30 as one kind 3 are arranged above imaging sensor 302, and for carrying camera lens 304, camera lens 304 includes camera lens carrier 30 as one kind 3
Adjustable lens 3041 (Tunable lens, T lens), wherein adjustable lens T lens 3041 is for deformation occurs after being powered
To focus.It is worth noting that, shown in Fig. 3 is only that a kind of specific camera module needs basis in practical applications
Specific application scenarios adjust accordingly.
In the present embodiment, camera module uses FPC soft board, it is possible to understand that and it is the plurality of advantages that FPC soft board has,
Such as 1. is flexible: it is more easily in three-dimensional space cabling and load, also rollable or fold up use, as long as allowing
Curling in range of curvature radius can be subjected to thousands of to tens of thousands of times and use and unlikely damage.2. reducing volume: in component load
In, the cross-sectional area of conductor of FPC soft board is thin and flat, reduces conductor size, and can shape along casing, makes the structure of equipment more
It is compact, reasonable, load volume is reduced, compared to printed circuit board (Printed Circuit Board, PCB), space can
Save 60~90%.3. alleviating weight: in same volume, FPC soft board is compared with leader cable, under identical current-carrying capacity,
Its weight can reduce about 70%, compared with pcb board, weight saving about 90%.4. increasing reliability: when using FPC soft board
When load, due to that can be routed in tri- planes of X, Y, Z, reduces switching interconnection, increase the reliability of whole system, and to event
The inspection of barrier, provides convenience.It of courses, camera module can also use pcb board, use FPC plate in the present embodiment
More excellent embodiment.It is worth noting that, in practical applications, which kind of wiring board is specifically selected flexibly to be adjusted by designer
Whole, the present invention is not specifically limited in this embodiment.
It is understood that the imaging sensor in camera module is also known as photosensitive element, being used for will be from camera lens Lens
The upper light to come that conducts is converted to electric signal, then is converted to digital signal by internal DA.In the present embodiment, image passes
Sensor can use charge coupled cell (Charge-coupled Device, CCD) or can also be aoxidized using complementary metal
Object semiconductor (Complementary Metal Oxide Semiconductor, CMOS).Wherein, CCD can directly believe optics
Analog current signal number is converted to, current signal realizes the acquisition, storage, transmission, place of image using amplification and analog-to-digital conversion
Reason and reproduction；CMOS is mainly the semiconductor being made into using two kinds of elements of silicon and germanium, by negatively charged and positively charged on CMOS
Transistor realize basic function.Common, CCD is the high-end technology element applied in terms of photography and vedio recording, and CMOS is answered
In product for lower image quality, compared with CCD, CMOS has small in size, the plurality of advantages such as power consumption is low, and price is low.
It is worth noting that, recited herein is only which kind of figure two kinds of common imaging sensors specifically select in practical applications
As sensor is adjusted flexibly by designer, the present invention is not specifically limited in this embodiment.
It will be clear that the camera lens carrier in the present embodiment is used to carry camera lens Lens, specifically, can be by camera lens
Lens is fixed on camera lens carrier by the effect of screw thread, or can be convex by the detent being arranged on camera lens Lens and camera lens carrier
It rises and is engaged, to be fixed on camera lens carrier.It is also noteworthy that recited herein is only two kinds of common generals
Camera lens is fixed on the mode on camera lens carrier, and the invention is not limited to both fixed forms, in practical applications, equally by
Designer is adjusted flexibly, and camera lens is fixed on any way on camera lens carrier in guarantor of the invention as long as being able to achieve
It protects in range.
It should be noted that the camera lens Lens in the present embodiment includes adjustable lens T lens, wherein adjustable lens T
Deformation occurs for meeting after lens is powered, and changes the focus point of light, to achieve the purpose that focus.Specifically, adjustable lens T
Lens is made of piezoelectric ceramics, silica gel and glass, and deformation occurs after piezoelectric ceramics is powered, and squeezes silica gel deformation occurs, is formed
The face of different curvature radius, to focus.It is understood that can occur after adjustable lens T lens energization concave or convex
The deformation risen, specifically, concave deformation occurs after being powered by piezoelectric ceramics, and squeezes silica gel and concave deformation occurs, and is formed
To focus, or the deformation of protrusion occurs for the face of different curvature radius after being powered by piezoelectric ceramics, and squeezes silica gel hair
The deformation of raw protrusion, forms the face of different curvature radius, to focus.It is worth noting that, recited herein is
The material of common adjustable lens T lens, while the two kinds of common deformation occurred based on the material, in practical applications, also
Flexible choice can be carried out to the material of adjustable lens T lens, deformation occurs as long as being able to achieve after adjustable lens T lens is powered
To reach the material for focusing purpose in protection category of the invention.
In the present embodiment, the adjustable lens T lens degree that deformation occurs, common, adjustable lens T are determined by voltage
Curvature of the lens after deformation occurs is positively correlated with the voltage being applied on adjustable lens T lens, in other words, with adjustable
Alive increase is applied on lens T lens, the adjustable lens T lens degree that deformation occurs is also bigger, and curvature is bigger, focal length
It is smaller.For a better understanding, being described in detail here with example.Firstly, concave shape occurs with adjustable lens T lens
Become example to be illustrated, for example, with reference to shown in Fig. 4-1, reset condition before being powered for adjustable lens T lens, i.e. adjustable lens
0V voltage is applied on T lens, optical path does not change at this time, referring to fig. 4 shown in -2, to apply on adjustable lens T lens
Adding the state of 10V voltage, it is to be understood that optical path is changed at this time, and directional light becomes diverging light, and referring to fig. 4-3
It is shown, it is the state that 20V voltage is applied on adjustable lens T lens, it is to be understood that and optical path changes at this time, and
Divergence of beam amplitude increases.Here it is also illustrated so that the deformation of protrusion occurs for adjustable lens Tlens as an example, for example, with reference to figure
Shown in 5-1, it is the reset condition before adjustable lens T lens is powered, is i.e. is applied with 0V voltage on adjustable lens T lens, at this time
Optical path does not change, and is the state that 10V voltage is applied on adjustable lens T lens referring to shown in Fig. 5-2, it is possible to understand that
, optical path is changed at this time, and directional light becomes gathering light, referring to shown in Fig. 5-3, to apply on adjustable lens T lens
The state of 20V voltage is added, it is to be understood that optical path changes at this time, and light gathers amplitude increasing.Thus not ugly
Out, as the increase of voltage amplitude, the curvature of adjustable lens T lens are increasing, focal length is reducing, therefore can pass through control
Voltage swing processed changes the focus point of light, focuses to realize.
It should be noted that the camera lens Lens in the present embodiment can also include eyeglass, it is to be understood that described here
Eyeglass that is to say common lens, specifically, plastic lens Plastic and glass lens Glass can be divided into, generally use
