Description
Technical field
The utility model is related to security monitoring technology, especially a kind of dust-proof double optical filtering switch.
Background technology
Under normal conditions, camera lens module includes camera lens, microscope base, double optical-filter switchers, driving circuit and sensitive chip.Mirror
The main function of head is exactly to filter off black light, allows visible light to enter, and project on sensor.
The bis- optical-filter switchers of IR-CUT be by：Optical filter+power section is constituted.The original of the bis- optical-filter switchers of IR-CUT
Reason is by one piece of circuit control panel and switch, and when the light on daytime is abundant, circuit control panel, which drives in switch, to be switched
It works to cutoff filter, switch restores true color, and when night insufficient light, cutoff filter is automatic
It removes, full spectrum light glass is started to work, and can incude the auxiliary light of evening infrared lamp, switch is made to make full use of all light
Line shines performance, entire picture clear and natural to substantially increase the low of thermal camera.
But some precision prescribed height and small camera, in order to reduce caused by light wave multipass light-transmitting component
Light losing and distortion, eliminate camera lens, and directly double optical filtering switch filter, and the optical filter of double optical filters needs to switch,
It is necessarily required to leave the space for smooth movement in handoff procedure, dust can enter module internal, existing city by this space
Such IR CUT designs are mostly not considered and designed to dust-proof used in safety monitoring on face, and the optical filter of switch carries
Body has with switch pedestal causes dust to be easy directly to fall on sensitive chip compared with big gap.
Utility model content
The purpose of this utility model is to provide a kind of dust-proof double optical filtering switch, reduces filter plate carrier and switch pedestal
Between gap, prevent dust from directly falling on sensitive chip.Based on the purpose, the technical solution adopted in the utility model is such as
Under：
A kind of dust-proof double optical filtering switch, including switch upper cover, switch pedestal, the thang-kng being set on switch pedestal
Hole, optical filter house the filter plate carrier of optical filter, power plant；The switch base intracavity is equipped with filter plate carrier branch
Stay, the switch base intracavity are equipped with dust ring, the top filter carrier of the dust ring close to the edge of light hole
The top of support bar is located at same level or the top less than filter plate carrier support bar.Extraneous dust enters from light hole
When, dust ring forms one of barricade, dust gear between light hole and dust ring, forms one of barrier.Dust ring highest and
It is concordant between filter plate carrier support bar, the support bar of filter plate carrier can also be slightly below, while blocking dust, not shadow
Ring the assembly between switch pedestal and switch upper cover.
Further, the filter plate carrier support bar is two, is arc-shaped；It includes close to light hole first
Stay, and second support bar opposite with the first support bar, the both ends of first support bar are close to the left and right of switch pedestal
Edge.The shape track of filter plate carrier support bar and the appearance and size of filter plate carrier match, and power plant drives optical filter
When carrier moves, the edge of filter plate carrier is always on filter plate carrier support bar.Support bar plays support filter plate carrier
Effect and serve as filter plate carrier tracks effect.
Further, the circular arc of two filter plate carrier support bars is isocentric circular arc.Support bar is arranged using concentric circles, filter
When mating plate carrier movement, edge on support bar, the movement locus of filter plate carrier and the support bar of filter plate carrier
Arc length is identical.
Further, switch pedestal one end opposite with filter plate carrier support bar is equipped with power plant accommodating cavity
Room.The power plant of switch is placed by power chamber resettling, and function division is apparent, opposite to form an enclosure space, to power
Device forms protection, while enhancing the intensity of switch pedestal so that switch is unlikely to deform, it is ensured that imaging precision.
Further, the cross section of the power plant chamber resettling is rectangle, and outer ledge is provided with " L " type
Supporting rib.Switch chamber resettling relative area is bigger, when wall ratio is relatively thin, easy tos produce the bad phenomenons such as fracture,
The especially on the corner place of stress concentration, it is easier to occur bad, " L " type supporting rib is set, chamber resettling is strengthened
Intensity has preferably protective effect to the indoor power plant of accommodating cavity.
Further, the switch pedestal is equipped with through-hole close to the second support bar inner opposite end.Filter plate carrier connects
On switch pedestal, axis is set in through-hole, under the driving of power plant, shaft rotation of the filter plate carrier in through-hole is dynamic, from
And achievees the purpose that optical filter and switch.
Further, the face that the dust ring is connected with switch pedestal is equipped with chamfering.Dust ring and switch pedestal one
Body formed, either casting and forming or injection molding, dust ring wall thickness all have certain limitations, in dust ring and switch pedestal
The place of intersection, stress concentration, if chamfering, dust ring is easy from bottom break, so setting chamfering, avoids dust ring
Fracture.
Further, ribs are equipped between the dust ring and the inner surface of switch pedestal.Due to by condition of molding
Limitation, the wall thickness of dust ring is all limited, and an individual ring body is easily deformed, and after deformation, will influence dust-proof effect, because
This can be avoided the fracture of dust ring with appropriately designed ribs.
Further, it is equipped with positioning column between the switch upper cover and switch pedestal, the switch upper cover and cuts
It is connected by hook and/or screw between parallel operation pedestal.The formation either county of all kinds of buckle is arm-type or circular ring type, he
Function be it is identical, constraint and separation function.It snaps connection and is not necessarily to other materials, reduce product cost, it is easy to operate, it fits
Should as plastic part assembling, product can repeat to remove dress and utilize.Screw connecting structure simple and compact, it is only necessary to which screwdriver just can
Realize dismounting.Screw connects hook connection and cuts both ways, and is selected according to the material and use occasion of switch upper cover and pedestal
Select use.Or two kinds of connection types are applied in combination.
The advantageous effect that the utility model obtains is：(1) by being equipped with dust ring close to thang-kng hole site in base intracavity,
When dust is fallen into from light hole, dust ring forms a barricade, prevents dust from falling on sensitive chip；(2) this practicality is new
Type is simple in structure, and dust ring and switch pedestal are integrally formed, and without increasing other processes and material, saves cost, is suitble to big
Batch is promoted.
