Abstract
The invention aims at providing an integrated day and night optical filter switch comprising a pedestal, a cover plate, a coil, a coil support, a rocking handle, a magnet, a PCB, and an electronic wire. A lens hole is arranged in the center of the cover plate. A lens seat is disposed on the lens hole. The inner loop of the lens hole is retracted towards a center to form an annular anti-outgoing surface in a diameter lower than that of the inner loop of the lens seat. Coil seats are symmetrically disposed in the front of the cover plate and in the front of the pedestal. The two symmetric coil seats are sunk towards the outside of a housing. According to the integrated day and night optical filter switch, since the anti-outgoing surface is disposed in the lens hole, a lens cannot damage the switch by pressure when being debugged by a user. The coil seats are sunk towards the outside of the housing; a driving part is fixed between the top coil and the bottom coil; and the height of the bottom frame of a plastic pedestal is reduced. Thus, the back focal distance is decreased and the applicability of a product is improved. The integrated day and night optical filter switch is especially suitable for wide-angle lenses in the market.
Description
Technical field
The present invention relates to a kind of pendulum model optical-filter switcher, especially a kind of integral type day and night optical-filter switcher.
Background technology
Optical filter is that one is used in various photography, additional functionality parts in the light path of monitoring equipment, such as when shooting or when making video recording, light in daytime the Nature comprises visible ray, infrared light and ultraviolet light, we can only see visible ray by human eye, and imageing sensor (senser) " can see " part infrared light except visible ray and ultraviolet light, the picture that these light make it photograph and the picture that our human eye is seen are not inconsistent (distortion), so in order to revise this distortion phenomenon, just need the imageing sensor (senser) for us to put on " glasses " (IR optical filter) and filter out all non-visible lights (infrared light and ultraviolet light), during to evening, the light in the Nature is mainly infrared light, and in order to capture the scene of this light and make more light enter sensor, we need to switch the another kind of optical filter of use (AR optical filter), make the picture of photography more clear.
Existing pendulum model optical-filter switcher structure exists, and 1. the assembly and connection of lens mount and IR-CUT comparatively bothers, and easily occurs connecting unstable phenomenon; 2. sensor frame and base are done split and are arranged, then are screwed in together, and assemble loaded down with trivial details, leakproofness is not good; 3. the fixed orifice of sensor frame both sides is plastic cement hole, and assembling steadiness is not good, easily occurs sliding dental phenomenon.
In order to solve the problem of existing pendulum model optical filtering switch, at Authorization Notice No. be: CN203350508U, the day for announcing is: describe a kind of Novel clock pendulum-type optical-filter switcher in the utility model patent file on Dec 18th, 2013, is made that the assembling of switch is more simple, structure is more firm by structure optimization.But the optical-filter switcher of this pendulum model, the coil holder of driver part is arranged on base, which adds the height of base underframe, increase back focal length from, cause the bad adaptability of product, especially, when being applied to wide-angle lens, the height of base underframe is more obvious for the impact of assembling.Meanwhile, client is when carrying out assembling and setting to product, and camera lens is easy to camera lens to twist into switch in the process of debugging, causes camera lens to damage switch by pressure.
Summary of the invention
The object of this invention is to provide a kind of integral type day and night optical-filter switcher, by the optimization of structure, practicality can be reached stronger, the object that the scope of application is wider.
In order to solve the problems of the technologies described above, technical scheme of the present invention is as follows: integral type is optical-filter switcher day and night, comprise base, cover plate, coil, coil brace, rocking handle, magnet, pcb plate, electric wire, the middle part of cover plate is provided with camera aperture, camera aperture is provided with lens mount, it is characterized in that: the anti-band of annular that the inner ring of described camera aperture is less than lens mount inner ring to center indentation formation diameter is appeared, the front end of cover plate and base is arranged with coil holder, and two symmetrical coil holders sink respectively to outside.
Improvement to technique scheme: described base is provided with multiple nut seat, and nut seat is embedded with nut, cover plate is provided with the screw corresponding with nut seat.
Beneficial effect:
Use integral type of the present invention day and night optical-filter switcher, be provided with anti-band in camera aperture and appear, when such client debugs camera lens, would not occur that camera lens damages the situation of switch by pressure; Coil holder sinks respectively to outside, is fixed in the middle of upper and lower coil holder by driving part, falls end plastic base underframe height, this reduces back focal length from, thus add the applicability of product, be particularly useful for the wide-angle lens adopted on market more.
In sum, the present invention, by the optimization of structure, improves the scope of application of product, makes the practicality of product stronger.
