Abstract
A camera filter automatic switching device comprises a box installed on a camera; the box is provided with a lens opening which is corresponding to the lens of the camera; an installing frame which can slide directionally is installed on the lens opening; two parallel filters are fixed on the installing frame; a drive component which drives the installing frame to move is fixed in the box; wherein, the drive component comprises a micro-motor and an reduction gear set which rotate synchronously with the output shaft of the micro-motor; and a rack which is meshed with the reduction gear set is installed on a fixing frame. Simultaneously, the two ends of the box on which the installing frames are installed are provided with buffer components which prevent the installing frames from being rigidly collided with the inner wall of the box when sliding to a limit position. The invention has the advantages of compact structure, small size, high reliability, easy installation, simple use and control, good filtering effect, strong universality, and the like. With the ordinary micro-motor and a precision drive mechanism, the camera filter automatic switching device is not only provided with the advantages of the existing products, but also avoids the original shortcomings, thereby being more capable of meeting the market demand.
Description
Technical field
The present invention relates to a kind of device that is applied in the camera, specifically a kind of automatic switching device for optical filter of camera head.
Background technology
The security protection camera has important effect for hitting to break laws and commit crime, and in the streets and lanes in a lot of cities the security protection camera is installed all.Because the security protection camera needs 24 hours shooting of whole day, must adapt to automatically daytime and night two kinds of light environments.At present, this function generally by blue color filter and the realization of white optical filter are installed at the camera front end, switches to blue color filter when daytime, switch to white optical filter evening, and the switching of two kinds of optical filters then needs finish by switching device shifter.
The switching device shifter that has the magnetic-type driving optical filter switching of electricity consumption now on the market, as shown in Figure 1.This magnetic-type switching device shifter mainly is the mobile switching that drives optical filter by electromagnet pull, and its price is lower, but reliability is not high, causes problems such as the not in place and off normal of work easily, can only be used for less demanding low side security product.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of easy for installation, reliable and stable automatic switching device for optical filter of camera head.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
A kind of automatic switching device for optical filter of camera head, comprise the casing that is installed on the camera, on casing, have the camera aperture corresponding with cam lens, the installing frame of orientable slip is installed on camera aperture, be fixed with two optical filters arranged side by side on the installing frame, in casing, be fixed with the drive installation moving driven unit of frameing shift, described driven unit comprises a micromachine and the train of reduction gears of rotating synchronously with the micromachine output shaft, and the tooth bar with the engagement of speed gear group is installed on fixed frame.
As improvement, be provided with when preventing that installing frame from sliding into extreme position and the buffer unit of cabinet wall generation rigid collision at the two ends of casing installation installing frame to such scheme.This buffer unit is the sheet metal corresponding with the installing frame end face, and sheet metal is provided with the shell fragment that arches upward to the installing frame direction, and shell fragment one end is unsettled.The shell fragment that is positioned at the same side is symmetrical two of installing, and the free end of two shell fragments is in the centre, and installing frame is provided with the lug boss that length is slightly larger than two free end spacings.When installing frame moved near extreme position under driven unit drives, lug boss contacted with the buffering that two shell fragments form, and prevented that installing frame and casing from producing rigid collision.
As improvement to such scheme, on the micromachine output shaft, be fixed with a worm screw, reduction gear component is connected with micromachine power by worm screw.This reduction gear component comprises and direct first duplicate gear of engagement of worm screw, also realizes that by two gears and an output gear wheel and rack power is connected between first duplicate gear and the tooth bar, and the direct and tooth bar of output gear meshes.
Compact conformation of the present invention, compact size, the reliability height, easy for installation, use control simple, filter effect is good, advantages such as highly versatile.By common micromotor and precision drive mechanism, had the advantage of existing product concurrently and avoided original defective, thereby also more can be satisfied with the demand in market.
Description of drawings
Accompanying drawing 1 is existing magnetic-type automatic switching device for optical filter of camera head structural representation;
Accompanying drawing 2 is an embodiment of the invention decomposing state structural representation;
Accompanying drawing 3 is a present embodiment assembled state structural representation;
Accompanying drawing 5 is a present embodiment buffer unit structural representation.
Embodiment
For the ease of those skilled in the art's understanding, structural principle of the present invention is further described in detail below in conjunction with specific embodiment and accompanying drawing:
Shown in accompanying drawing 2～5, the automatic switching device for optical filter of camera head that this scheme disclosed adopts that existing volume is little, the micromachine of stable performance is as power, and adopts the stable gear of transmission as drive disk assembly, and volume is little, stable can be high.
Driven unit 3 is used for drive installation frame 2 drives two optical filters 21 and switches on camera aperture 11.Driven unit 3 comprise one be fixed in the casing 1 micromachine 31 and be installed on the train of reduction gears 32 that worm screw 311 engagements are rotated synchronously on micromachine 31 output shafts, on fixed frame 2, then be provided with tooth bar 33 with 32 engagements of speed gear group.Reduction gear component 32 comprises with worm screw 311 and directly also is provided with two gears and an output gear 322 between first duplicate gear, 321, the first duplicate gears 321 and the tooth bar 33 of engagement that output gear 322 and tooth bar 33 directly mesh.
Produce big rigid collision when preventing that driven unit 3 drive installation frames 2 from moving to extreme position and contact with casing 1 inwall, be provided with the buffer unit 4 of buffering at casing 1 inwall.In the present embodiment, buffer unit 4 is and the corresponding sheet metal of installing frame 2 end faces that sheet metal is provided with the shell fragment 41 that arches upward to installing frame 2 directions, shell fragment 41 1 ends are unsettled, and be provided with the shell fragment that two symmetries are installed, in the middle of the free end of two shell fragments was positioned at, two free ends had a determining deviation.And be provided with the lug boss 22 that length is slightly larger than spacing at installing frame 2 end faces.When installing frame 2 under the driving of driven unit 3 near shell fragment 41 after; at first lug boss 22 contacts and cushions with shell fragment 41; prevent that installing frame 2 and casing 1 inwall generation rigid collision from damaging optical filter 21 or causing optical filter 21 and installing frame 2 skew trams, can protect also that each gear is subjected to impact failure in the reduction gear component 32.
