Problems solved by technology

[0002] In security equipment products, infrared cameras are widely used. The filters of infrared cameras include the first filter and the second filter, which need to be switched frequently during work to take into account the shooting effects of day and night. If the filter If the chip switcher is not smooth or even stuck during the switching process, it will cause the image captured by the infrared camera to be black and hazy at night, and slightly reddish during the day, seriously affecting the image quality
[0003] The filter switcher currently on the market is usually a motor plus rack and pinion structure or a cam structure. The structure is relatively complicated, and the entire structure is relatively large, so the production efficiency is low and the cost is high.
Moreover, the switching method of this structure is a pendulum shaking, which is greatly affected by gravity, and it is easy to cause a crash when switching

Embodiment Construction

[0022] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] see Figure 1-Figure 3 A preferred embodiment of the filter switcher of the present invention is shown. The optical filter switcher of this embodiment includes a base 100, a cover plate 300 and a frame 200 equipped with an optical filter. The base 100 is provided with an opening 110, and the middle part of the opening 110 is provided with a light hole 111. The opening The base 100 on the left side of 110 is provided with a groove 120 with a size of about 1x1.5x9; the filter includes a first filter 210 fixed on the left side of the frame 200 and a second filter fixed on the right side of the frame Light sheet 220; the frame 200 is placed in the opening cavity 110, the cover plate 300 is fixed on the base 100 by means of screw connection, etc., the opening cavity 110 is covered by the cover plate 300 to form a c...

Abstract

The invention discloses an optical filter switcher and a camera. The optical filter switcher comprises a base provided with an opening, a cover fixed to the base and a frame equipped with an optical filter. The opening is covered by the cover Finally, a cavity for accommodating the frame is formed, and the frame can slide laterally in the cavity. A first electromagnet with variable magnetic pole is arranged on the base or cover plate on one side of the cavity, and the frame is close to One end of the first electromagnet is provided with a first permanent magnet, and the north and south poles of the first electromagnet and the first permanent magnet are arranged laterally along the base. Utilizing the principle of same-sex repulsion and opposite-sex attraction of magnets, the frame is attracted or repelled by changing the magnetic poles of the electromagnet, so that the frame slides laterally in the cavity, thereby realizing the smoothness of the filter with low cost and simple structure. switch.
