Abstract

The invention discloses a visible light and near-infrared light switching mechanism based on electromagnetic driving. The visible light and near-infrared light switching mechanism comprises a base, alight filtering assembly arranged at the lower part of the base and an electromagnetic driving assembly arranged at the upper part of the base; the light filtering assembly comprises a visible light filter, a near-infrared light filter, a light filter seat and a pin; and the electromagnetic driving assembly mainly comprises a coil seat, a swing rod and a coil. According to the visible light and near-infrared light switching mechanism based on electromagnetic driving provided by the invention, an electromagnetic driving mode is adopted, and by changing the positive electrode and the negative electrode of the current input into the coil, the electromagnetic field magnetic pole directions are switched; when the direction of the electromagnetic field magnetic pole generated by the coil is opposite to the magnetic pole direction of a magnet, the magnetic field drives the swing rod to rotate, and the switching of the visible light filter and the near-infrared light filter is driven, so thata visible light working mode or the near-infrared light working mode can be switched. By virtue of the electric signal control based on electromagnetic driving, the power consumption of the system islowered, the reliability is enhanced, the light filters are rapidly switched, and the actual combat reaction capacity is improved.

Description

technical field [0001] The invention belongs to the technical field of photoelectric equipment, and in particular relates to an electromagnetically driven visible light and near-infrared light switching mechanism. Background technique [0002] The definition of electromagnetic drive is that if the magnetic field moves relative to the conductor, an induced current will be generated in the conductor, and the induced current will cause the conductor to be affected by the Ampere force, and the Ampere force will make the conductor move. This driving method is called electromagnetic drive. [0003] Military visible light or near-infrared light working mode switching mechanism is mainly used for military white light imaging reconnaissance equipment. This equipment is generally composed of photoelectric sensors, optical lenses, etc. The photoelectric sensor can sense visible light and near-infrared light at the same time. Different refractive indices are different, and after refract...
