It is easy to control, so as to the shake angle and vibration frequency of more accurate control photographic device, simulated according to the requirement of client
Artificial hand shaking, reaches the requirement of client, furthermore it is possible to reduce noise, structure is simple, can be obtained very big with save the cost
Economic benefit saves each component time buying.
Further, as shown in figure 4, as board group part 30 further includes the first trapped orbit 32 and the second trapped orbit 33.Its
In, as plate 31 and support plate 20 are oppositely disposed, it is suitable for photographic device acquisition as the image on plate 31.First trapped orbit, 32 He
Second trapped orbit 33 is at a distance of the first pre-determined distance, and the first trapped orbit 32 and the second trapped orbit 33 are set with as plate 31 is vertical
It sets, for fixed as plate 31.
In order to meet different demands, setting can be adjusted as plate 31 with longitudinal separation, as shown in figure 4, as board group part 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 at a distance of second it is default away from
It is arranged on cabinet 10 from, the first sliding rail 34, by the first sliding rail 34 and the second sliding rail 35 as plate 31 can be with
It slides back and forth, so as to change as plate 31 is at a distance from support plate 20, meets the needs of different.
Further, in order to guarantee as the accuracy that distance is adjusted between plate 31 and support plate 20, as shown in figure 4, can be with
Distance scale 02 is set on the outer surface of cabinet 10 corresponding with the first sliding rail 34, it is, can be in the first sliding
Scale is set on the outer surface of the side of the corresponding cabinet 10 of track 34, alternatively, scale or two sides are arranged on an internal surface all
Distance scale is set, so as to adjust as the distance between plate 31 and support plate 20 more accurately.
It is realized below by OIS optical anti-vibration test device 100 of the specific embodiment to the embodiment of the present invention and adjusts camera shooting
The process that the tilt angle and vibration frequency of device simulate artificial hand shaking is described in detail.
In one embodiment of the invention, as shown in figure 5, driving assembly 50 includes drive shaft 51 and link member 52.
Wherein, drive shaft 51 is connect with support plate 20, passes through the front and rear tilt angle of the adjustable support plate 20 of the movement of drive shaft 51.
As shown in fig. 6, link member 52 includes connecting rod 521 and off-centre operation shaft 522, off-centre operation shaft 522 is connect with drive shaft 51, even
One end of bar 521 is nested with off-centre operation shaft 522, and the other end of connecting rod 521 is connect with motor 40.Specifically, off-centre operation turns
The distance between axis 522 and drive shaft 51 can be set according to experiment value.Motor 40 passes through connecting rod 521 after start-up
The mobile pre-determined distance of off-centre operation shaft 522 is driven so that drive shaft 51 shakes angle needed for driving support plate 20 to rotate, wherein pre-
If distance is the eccentric distance of off-centre operation shaft 522.
In one embodiment of the invention, the eccentric distance of off-centre operation shaft 522, example can be obtained by geometrical relationship
Such as, as shown in fig. 6, passing through triangle letter according to the distance between off-centre operation shaft 522 and drive shaft 51 and required shake angle
Number relationship obtains the eccentric distance of off-centre operation shaft 522.In practice, by off-centre operation shaft 522 and the fixed company of drive shaft 51
It connects, it is 102.5mm that length between the two, which is fixed such as length, according to two-dimentional drawing and ambient enviroment demand, besides root
According to client requirement for example: it is 0.7 degree that board, which shakes angle, 45 degree of Camera rotation, and the vibration angle that sets of board as
Camera specificationTimes, according to this requirement, as shown in Fig. 2 or Fig. 5, the angle of support plate 20 rotates 45 degree and namely images
Device such as Camera rotates 45 degree, and besides in order to meet the requirement that client shakes angle, then design shake angle isIt is, support plate 20 needs to tilt 1 degree, and then according to trigonometric function principle, as shown in fig. 7, can be in the hope of another
The length of one right-angle side, that is, the eccentric distance of off-centre operation shaft 522, for example, setting unknown for the distance of off-centre operation
Number X, then meet tan1=X/102.5, so that obtaining eccentric distance is illustrated in figure 8 X=1.3.And then according to the eccentric distance
Radius, that is, 1.3mm of off-centre operation shaft 522 is designed, this is inclined so that motor 40 is by the movement of the drive off-centre operation shaft 522 of connecting rod 521
Such as 1 degree of angle of shake needed for heart distance may make 51 driving support plate 20 of driving rotation to tilt, then support plate 20 namely images
Device is shaken with ± 1 degree, meets the angle requirement of client.With the irregular phase of photographic device swing angle in the related technology
Than, the embodiment of the present invention device 100 by using trigonometric function principle link rotatable so that vibration angle control is more smart
Really.
In addition, test device 100 simulates artificial hand shaking, need to realize that the left-right and front-back of photographic device is swung, setting carries
Plate 20 deviates 45 degree of namely photographic devices and deviates 45 degree, then need to only realize the swing of the left and right of photographic device.In this hair
In bright embodiment, the revolving speed by controlling motor 40 realizes the control of vibration frequency.Specifically, above-mentioned apparatus 100 further includes
Pressure regulator, pressure regulator are used to adjust the revolving speed of motor 40 so that motor 40 reaches preset rotation speed, to meet support plate 20 namely
The control of the vibration frequency of photographic device.For example, being 6 times/second according to the requirement vibration frequency of client, if motor 40 is with minute
I.e. 360 beats/min are calculated, revolving speed and vibration frequency ratio are 1:40, then may make vibration frequency when showing 009 on pressure regulator
Rate reaches 360 beats/min, it is possible to reduce error, it is clear that.With in the related technology, carry out OIS test when, with photographic device
The motor of itself realizes that vibration is compared, and realizes that the adjusting of vibration frequency, frequency control are more accurate by motor 40.
Further, as shown in figure 5, above-mentioned OIS optical anti-vibration test device 100 further includes display 60, display 60
On cabinet 10, the corresponding vibration frequency of revolving speed for showing motor 40 shakes frequency so as to more accurate adjusting
Rate, in the related technology cannot show vibration frequency, shown by display 60, more intuitively, can be as much as possible
Reduce error.The regulating switch 03 of pressure regulator and the start stop switch 04 of motor 40 can also be set on cabinet 10.
In addition, as shown in fig. 1, generally support plate in the related technology includes one, in an embodiment of the present invention, carry
Plate 20 can be designed to two, acquire pictures by two support plates 20 namely two photographic devices, and imaging can be formed pair
Than, it will be apparent that find out the clarity of two photographic devices, more intuitively.
