Switching mechanism for photographic device

Abstract

The invention relates to a switching mechanism for photographic device, which comprises a control unit, a driving device, a first gear bank, a second gear, a spindle, a translation mechanism, wherein the driving device is connected with the control unit and is controlled by the control unit to act; the first gear bank is connected with the driving device; the second gear is connected with the first gear bank, a rotating shaft having a shaft hole is arranged in the center of the second gear and the shaft hole has threads; the second gear passes through the shaft hole to be sleeved on the spindle, the axial surface of the spindle is provided with external threads corresponding to the threads of the shaft hole, and thus, the second gear can move relatively on the spindle; and the translation mechanism is perpendicular to the spindle and is provided with a first rack meshed with the second gear, and the rack drives the translation mechanism to shift in a direction vertical to the spindle so that the translation mechanism can conduct a motion behavior of meshing the second gear partially.

Description

technical field [0001] The present invention relates to a switching mechanism applied to a photographic device, in particular to a light filtering mechanism for a photographic device with a simple mechanism, low noise, low wear, and no need for complex control and feedback units. slice switching mechanism. Background technique [0002] Whether a general photographic device uses a charge coupled device (Charge Coupled Device, CCD) or a complementary metal oxide semiconductor (Complementary Metal Oxide Semiconductor, CMOS) sensing element, in order to maintain a relatively high image capture state during the day and night In order to maintain a high image fidelity during the day and operate clearly at night, it is necessary to switch the filter between night and day. Therefore, this is a structure with the function of switching filters that is commonly used on photographic devices. [0003] There are many ways to achieve the switching mechanism of the above-mentioned switchi...

Problems solved by technology

The advantage of this method is that a smaller and simpler mechanism can be used to achieve the action target, and the cost is relatively low; however, there are inherent control shortcomings that cannot be overcome, that is, the state of the controlled object and the noise problem cannot be grasped

[0006] It can be seen that the above-mentioned existing switching mechanism applied to the photographing device obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general product has no suitable structure to solve the above-mentioned problems. This is obviously the relevant industry. Urgent problem
