Description
Technical Field
The utility model relates to a light filter switch field, in particular to anti-sticking stops light filter switch.
Background
The optical filter switcher is characterized in that a group of filters are arranged in the camera lens, and when the infrared sensing points outside the camera lens detect the change of the intensity of light, the filters can automatically switch according to the intensity of external light, so that the image achieves the best effect; therefore, the best imaging effect can be obtained no matter in daytime or at night. The motor optical filter switcher switches double optical filters by positive and negative rotation of a miniature worm on a high-speed micromotor, and is applied to the fields of law enforcement recorders, automobile data recorders, vehicles, network cameras and the like.
The mainstream product in the market is that the motor directly promotes the light filter and removes, and the motor produces the skew easily because the atress is uneven in the motion trail of promoting the light filter, and does not have effectual spacing on structural design, leads to this product card dead in the work, influences the normal use of complete machine product, causes a great deal of adverse reaction in market and user complains. In order to ensure the quality of the shipment, manufacturers need to perform multiple screening in the production process, which causes a lot of working hours and waste of raw materials, resulting in increased cost.
SUMMERY OF THE UTILITY MODEL
The utility model provides a dead light filter switch of anti-sticking to solve at least one above-mentioned technical problem.
In order to solve the above problem, as an aspect of the present invention, there is provided an anti-jamming optical filter switch, including: the optical filter comprises a shell, a motor, a guide rod and an optical filter tray, wherein the motor, the guide rod and the optical filter tray are all installed in the shell, the upper side and the lower side of the optical filter tray are respectively connected with one guide rod in a sliding mode, a rotating shaft of the motor is fixedly provided with a driving spring, a guide part matched with the driving spring is arranged on the optical filter tray, and the guide part is clamped in a spiral guide groove formed by the rotating shaft and the driving spring.
Preferably, two filters are disposed on the filter tray.
Preferably, the guide portion is U-shaped.
The utility model has the advantages of smooth and controllable motor movement track, stable promotion of optical filter switching, reliable use of products, solving of the problem of optical filter jamming in the industry, guaranteed image quality of camera shooting, no increase in product volume and compatibility with mainstream products in the market; the production process is easy to control, and the manufacturing cost of the product is reduced.

fig. 2 schematically shows an exploded view of the invention.
Reference numbers in the figures: 1. a housing; 2. a motor; 3. a guide bar; 4. a filter tray; 5. a drive spring; 6. a guide portion; 7. and (3) a filter.
Detailed Description
The embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways as defined and covered by the claims.
An aspect of the utility model provides an anti-sticking is dead light filter switch, include: the optical filter comprises a shell 1, a motor 2, a guide rod 3 and an optical filter tray 4, wherein the motor 2, the guide rod 3 and the optical filter tray 4 are all installed in the shell 1, the upper side and the lower side of the optical filter tray 4 are respectively connected with one guide rod 3 in a sliding mode, a rotating shaft of the motor 2 is fixedly provided with a driving spring 5, the optical filter tray 4 is provided with a guide portion 6 matched with the rotating shaft and the driving spring 5, and the guide portion 6 is clamped in a spiral guide groove formed by the rotating shaft and the driving spring 5. Preferably, two filters 7 are disposed on the filter tray 4. Preferably, the guide 6 is U-shaped.
When the device works, the motor 2 rotates, and the force arm is shortened by utilizing the principle of mechanics and through the matching structure between the spiral guide groove and the guide part 6; in addition, the optical filter is fixed on the guide rod, after the power is switched on, the rotating shaft of the motor rotates, and the driving spring 5 is fixed on the rotating shaft, so that the connection between the rotating shaft of the motor and the guide part 6 is more stable and reliable, the rotating shaft on the motor 2 and the fixed driving spring 5 are utilized to drive the guide part 6 to slide along the guide rod together, the stable movement of the optical filter fixed on the guide rod is realized, the comfortable switching of the double optical filters is realized, and the problem of the blocking of the optical filter is effectively solved.
The utility model has the advantages of smooth and controllable motor movement track, stable promotion of optical filter switching, reliable use of products, solving of the problem of optical filter jamming in the industry, guaranteed image quality of camera shooting, no increase in product volume and compatibility with mainstream products in the market; the production process is easy to control, and the manufacturing cost of the product is reduced.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
