Description
Technical field
The utility model belongs to camera technique field, relates in particular to a kind of noiseless pair of optical-filter switcher.
Background technology
Nature exists the light of various wavelength, can see the light of different colours by refraction human eye, and the wavelength difference of Here it is light causes, and wherein comprises infrared light, existing common people are divided into closely, in, far infrared three parts.Wherein, near infrared refers to that wavelength is 0.75～3.0 micron; In infrared finger wavelength be 3.0～20 microns; Far infrared refers to that wavelength is 20～1000 microns.Due to mixing of various light, the object that video camera is seen is reflected on monitor and just having changed that human eye is directly seen, and as human eye is seen green, becomes blueness by video camera, produces color distortion.For avoiding this problem, night viewing camera adopts two optical-filter switcher IR-CUT to control light.The two optical-filter switchers of IR-CUT be by: optical filter+power section+metal clips forms, wherein.Optical filter comprises a slice cutoff filter and a slice high-pass filter, and power section is motor, and primary clustering forms and concrete acting on as following table:
| Sequence number | Title | Effect |
| 1 | Plastic body (housing) | Structure carrier |
| 2 | IR optical filter | IR-cut eyeglass |
| 3 | AR optical filter | High pass eyeglass |
| 4 | Motor | Driving force |
| 5 | Metallic rod | Optical filter sliding support |
| 6 | Metal clips | Optical filter buffering is fixing |
But existing IR-CUT can produce sound, and it is mainly the collision deriving between optical filter and slide bar.
Utility model content
The purpose of this utility model is to provide a kind of noiseless pair of optical-filter switcher, and be intended to solve existing IR-CUT and all can produce sound, be mainly the problem that derives from the collision between optical filter and slide bar.
A kind of noiseless pair of optical-filter switcher is provided, comprise housing, be arranged at the fixed support of the outer bottom of described housing, be arranged at the lead rail axis of a side in described housing, be arranged at the motor of opposite side in described housing, be placed on the motor spring in the Metallic rod of described motor, the filter support of center section in described housing is set, be placed in the first optical filter and the second optical filter on described filter support, and be arranged at respectively two buffering spring sheets of opposing sidewalls in described housing, wherein, one end of described filter support is connected with described motor spring, the other end of described filter support is connected in described lead rail axis, when described electrical power rotates, drive the described motor spring in described Metallic rod to rotate, the planar slide that the rotation of described motor spring drives described the first optical filter and described the second optical filter to form along described Metallic rod and described lead rail axis, to complete described the first optical filter and described the second optical filter switching action, while switching each time, described the first optical filter or described the second optical filter can withstand buffering spring sheet described in one of them, the pressure of described buffering spring sheet is fixed described the first optical filter or described the second optical filter.
Further, described buffering spring sheet is SUS304 stainless steel.
Further, the thickness of described buffering spring sheet is 0.2mm.
Further, the hardness number of described buffering spring sheet comprises 300～400 Vickers hardnesses.
Further, described the first optical filter is specially infrared fileter, and described the second optical filter (8) is specially transparent optical filter.
The utility model embodiment, by buffering spring sheet is set, makes optical filter be close to buffering spring sheet by the pressure of buffering spring sheet, has reduced optical filter abnormal motion, optical filter can not be rocked, and then reach without sound effective value.
