Obtain the biggest economic benefit, save each parts time buying.
Further, as shown in Figure 4, the first trapped orbit 32 and the second trapped orbit 33 is also included as board component 30.
Wherein, as plate 31 is oppositely disposed with support plate 20, it is suitable for camera head collection as the image on plate 31.First retaining rail
Road 32 and the second trapped orbit 33 are at a distance of the first predeterminable range, and the first trapped orbit 32 and the second trapped orbit 33 and picture
Plate 31 is vertically arranged, for fixing as plate 31.
In order to meet different demand, arrange as plate 31 can regulate with longitudinal separation, as shown in Figure 4, as board component 30 also wraps
Include the first sliding rail 34 and the second sliding rail 35.First sliding rail 34 and the second sliding rail 35 are pre-at a distance of second
If distance, the first sliding rail 34 is arranged on casing 10, by the first sliding rail 34 and the second sliding rail 35 picture
Plate 31 such that it is able to change as the distance of plate 31 with support plate 20, can meet different demands with slide anteroposterior.
Further, in order to ensure as the accuracy of plate 31 with the spacing regulation of support plate 20, as shown in Figure 4, permissible
The outer surface of the casing 10 corresponding with the first sliding rail 34 arranges distance scale 02, it is, can be sliding first
On the outer surface of the side of the corresponding casing 10 of dynamic track 34, scale is set, or, scale is set on an internal surface, or
Two sides all arranges distance scale, such that it is able to more accurately regulate as the distance between plate 31 and support plate 20.
Below by specific embodiment, the OIS optical anti-vibration of the embodiment of the present invention is tested device 100 and realize regulation camera head
Angle of inclination and the vibration frequency simulation process trembled of artificial hand be described in detail.
In one embodiment of the invention, as it is shown in figure 5, drive assembly 50 to include drive shaft 51 and link member
52.Wherein, drive shaft 51 is connected with support plate 20, can regulate support plate 20 by the movement of drive shaft 51
Tilt forward and back angle.As shown in Figure 6, link member 52 includes connecting rod 521 and off-centre operation rotating shaft 522, off-centre operation rotating shaft 522
Being connected with drive shaft 51, one end of connecting rod 521 is nested with off-centre operation rotating shaft 522, and the other end of connecting rod 521 and motor
40 connect.Specifically, the distance between off-centre operation rotating shaft 522 and drive shaft 51 can be set according to experiment value.
Motor 40 drives off-centre operation rotating shaft 522 to move predeterminable range so that drive shaft 51 drives by connecting rod 521 after start-up
Support plate 20 rotates required shake angle, and wherein, predeterminable range is the eccentric distance of off-centre operation rotating shaft 522.
In one embodiment of the invention, can be by the eccentric distance of geometrical relationship acquisition off-centre operation rotating shaft 522, such as,
As shown in Figure 6, trigonometric function is passed through according to the distance between off-centre operation rotating shaft 522 and drive shaft 51 and required shake angle
Relation obtains the eccentric distance of off-centre operation rotating shaft 522.In practice, connect fixing with drive shaft 51 for off-centre operation rotating shaft 522
Connect, length between the two is fixed the most a length of 102.5mm, besides according to two dimension drawing and surrounding demand
Requirement according to client is such as: board vibrations angle is 0.7 degree, and Camera rotates 45 degree, and the vibrations angle of board setting
Degree is Camera specificationTimes, according to this requirement, as shown in Fig. 2 or Fig. 5, the angle of support plate 20 rotates 45 degree
Namely camera head such as Camera rotates 45 degree, shakes the requirement of angle besides in order to meet client, then designs institute
Need to shake angle isIt is, support plate 20 needs 1 degree, and then according to trigonometric function principle, such as figure
Shown in 7, can be in the hope of the length of another right-angle side, the eccentric distance of namely off-centre operation rotating shaft 522, such as, will be partially
The distance of heart circle is set to unknown number X, then meet tan1=X/102.5, thus obtain eccentric distance and be illustrated in figure 8 X=1.3.
And then according to the radius i.e. 1.3mm of this eccentric distance design off-centre operation rotating shaft 522, thus motor 40 is driven by connecting rod 521
Off-centre operation rotating shaft 522 is moved this eccentric distance and can be made to drive rotation 51 driving support plates 20 to tilt required shake angle such as
1 degree, then support plate 20 namely camera head shakes with ± 1 degree, meets the angle requirement of client.Take the photograph with correlation technique
Compare as device pendulum angle is irregular, the device 100 of the embodiment of the present invention by use trigonometric function principle link rotatable,
Make to shake Angle ambiguity more accurate.
It addition, test device 100 is simulated artificial hand and trembled, need the left-right and front-back realizing camera head to swing, support plate is set
20 skew 45 degree namely camera heads offset 45 degree, the most only need to realize the swing of the left and right of camera head.At this
In bright embodiment, realize the control of vibration frequency by controlling the rotating speed of motor 40.Specifically, said apparatus 100 also wraps
Including pressure regulator, pressure regulator is for regulating the rotating speed of motor 40 so that motor 40 reaches preset rotation speed, thus meets support plate 20 also
It is exactly the control of the vibration frequency of camera head.Such as, it is 6 times/second according to the requirement vibration frequency of client, if motor
40 calculate i.e. 360 beats/min in minutes, and rotating speed and vibration frequency ratio are 1:40, then when showing 009 on pressure regulator
Vibration frequency can be made to reach 360 beats/min, it is possible to reduce error, it is clear that.With correlation technique, carry out OIS survey
During examination, realize vibrations with the motor of camera head self and compare, realized the regulation of vibration frequency, FREQUENCY CONTROL by motor 40
More accurate.
Further, as it is shown in figure 5, above-mentioned OIS optical anti-vibration test device 100 also includes display 60, display 60
It is positioned on casing 10, for showing the vibration frequency that the rotating speed of motor 40 is corresponding, such that it is able to regulate vibrations more accurately
Frequency, with correlation technique can not show vibration frequency, shown by display 60, more intuitively, can to the greatest extent may be used
Error can be reduced in ground.Regulation switch 03 and the start stop switch 04 of motor 40 of pressure regulator can also be set on casing 10.
It addition, as shown in fig. 1, usually the support plate in correlation technique includes one, in an embodiment of the present invention, carries
Plate 20 can be designed to two, gathers picture by two support plates 20 namely two camera heads, and its imaging can be formed
Contrast, it will be apparent that find out the definition of two camera heads, more intuitively.
