Abstract

The utility model provides a kind of double filter camera lens base devices, it include: lens mount, pallet and motor, optical filter is installed on the pallet, the motor drives the tray motion, the pallet and motor are all set in the lens mount, limit blocking portion is formed in the lens mount, the limit blocking portion is located on the motion path of the pallet.When motor rotates and drives pallet along linear slide, position-limiting action can be played to pallet by limit blocking portion, to improve producing line yield and eliminate product to terminal client quality problems, it is possible that preventing lens tray from exceeding the stroke of motor, solve due to it is stuck when overtravel causes eyeglass to drive to motor starting point, cause not switch or phenomena such as defective products flows out.

Description

Double filter camera lens base devices

Technical field

The utility model relates to camera technique field, in particular to a kind of double filter camera lens base devices.

Background technique

The bis- filters of IR-CUT have referred in cam lens group one group of filter built-in, when the infrared induction point outside camera lens is detectd After the strong and weak variation for measuring light, built-in IR-CUT can be automatic therewith according to the power of extraneous light by motor switching filter Switching, makes image reach optimum efficiency.That is, double optical filters can automatically switch filter, therefore under daytime or night Whether under daytime or night, optimal imaging effect can be obtained.

But it is existing stroke in lens mount when eyeglass is changed by motor switchback, when tray motion is to end, easily block Pallet, so as to cause that can not switch.

Utility model content

The utility model provides a kind of double filter camera lens base devices, to solve the above technical problems.

To solve the above problems, the one aspect as the utility model, provides a kind of double filter camera lens base devices, packet Include: lens mount, pallet and motor are equipped with optical filter on the pallet, and the motor drives the tray motion, the pallet It is all set in the lens mount with motor, limit blocking portion is formed in the lens mount, the limit blocking portion is located at institute It states on the motion path of pallet.

Preferably, double filter camera lens base devices further include spring, and the spring is fixedly arranged at the motor On output shaft, the side of the pallet has been protrudedly formed the first guide part, and first guide part is actively covered described defeated It is formed by gap between screw on shaft and positioned at the spring.

Preferably, the other side of the pallet has been protrudedly formed the second guide part, and guiding is provided in the lens mount Bar, second guide part are flexibly connected with the guide rod.

Preferably, the limit blocking portion is arranged at position corresponding with first guide part.

Preferably, double filter camera lens base devices further include upper cover, and the upper cover is fastened with the lens mount to be formed For accommodating the accommodation space of the pallet and motor.

When motor rotates and drives pallet along linear slide, position-limiting action can be played to pallet by limit blocking portion, from And improve producing line yield and eliminate product to terminal client quality problems, it is possible to prevent lens tray exceed motor row Journey, solve due to it is stuck when overtravel causes eyeglass to drive to motor starting point, cause not switch or defective products outflow Phenomena such as.

Specific embodiment

The embodiments of the present invention are described in detail below in conjunction with attached drawing, but the utility model can be by right It is required that the multitude of different ways for limiting and covering is implemented.

The one aspect of the utility model provides a kind of double filter camera lens base devices, for installing fixed video camera mirror Head and IR CUT (optical-filter switcher), especially suitable for all security monitoring cameras.

Double filter camera lens base devices include: lens mount 1, pallet 2 and motor 3, are equipped with optical filter 4 on the pallet 2, The motor 3 drives the pallet 2 to move, and the pallet 2 and motor 3 are all set in the lens mount 1, the lens mount 1 It is inside formed with limit blocking portion 5, the limit blocking portion 5 is located on the motion path of the pallet 2.

The power part of the utility model is motor, and when the light on daytime is abundant, external circuit control panel drives horse Dutch changes, and the cutoff filter work to work by day avoids the chromatic distortion on daytime, CMOS restores true coloured silk Color；When night insufficient light, cutoff filter is removed using motor, so that CMOS is made full use of all light, avoids In the infrared optical issue of night light disturbance, to substantially increase low according to performance, avoids and ask night light disturbance is infrared Topic then can obtain optimal imaging visual effect on daytime and night.

It, can be right by limit blocking portion 5 when motor rotates and drives pallet along linear slide in above-mentioned handoff procedure Pallet plays position-limiting action, to prevent lens tray from exceeding the stroke of motor, cause lens tray drive to motor starting point and by It is stuck, cause not switch or phenomena such as defective products flows out, is subject to this limit blocking portion and solves this problem in that improve producing line Yield and eliminate product to terminal client quality problems.

Preferably, double filter camera lens base devices further include spring 6, and the spring 6 is fixedly arranged at the motor 3 Output shaft 7 on, the side of the pallet 2 has been protrudedly formed the first guide part 8, and first guide part 8 actively covers It is formed by gap between screw on the output shaft 7 and positioned at the spring 6.During motor rotation, spring 6 is formed Gap between screw play the role of spirally-guided, to make tray both slid, switch over.

Preferably, the other side of the pallet 2 has been protrudedly formed the second guide part 9, is provided with and leads in the lens mount 1 To bar 10, second guide part 9 is flexibly connected with the guide rod 10.

Preferably, the limit blocking portion 5 is arranged at position corresponding with first guide part 8.

Preferably, double filter camera lens base devices further include upper cover 11, the upper cover 11 and the lens mount 1 fasten with Form the accommodation space for accommodating the pallet 2 and motor 3.

The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
