Light and small photoelectric pod

Abstract

The invention discloses a light and small photoelectric pod which comprises a horizontal rotating shaft system and a high-low rotating shaft system. The horizontal rotating shaft system comprises a casing, a first torque motor, a first angle measurement encoder and an electronic circuit board group. A first bearing and a flange are installed on a rotating shaft of the first torque motor. The casing is provided with an upper cover plate, and a power module is installed on the upper cover plate. The high-low rotating shaft system comprises a U-shaped frame and a side cover. A motor shaft system and an angle measurement shaft system are arranged in a cavity formed by the U-shaped frame and the side cover. The high-low rotating shaft system is provided with a sealed spherical cavity, and a sensor group is disposed in the spherical cavity. High-precision dual axis gyroscope stability and no-backlash design of the torque motor are adopted, a nested shaft system structure is adopted, outline dimensions and weight are compressed to the largest extent, a sensor focal length and an installation space are expanded to the largest extent, the whole pod is sealed in appearance, and the pod is a light and small high-performance photoelectric pod device suitable for being used in a severe environment.

Description

technical field [0001] The invention belongs to the field of optoelectronics, and specifically relates to a light and small photoelectric pod, which is suitable for installation in various manned aircraft or unmanned aerial vehicles, and can also be installed in land-based, vehicle-mounted, and ship-borne applications, and is especially suitable for remote control flight video Detection and reconnaissance, high-precision, high-definition video imaging or target indication for the target area. Background technique [0002] In recent years, UAV technology has developed rapidly. Airborne photoelectric pods are the most important payload of UAVs, and their performance directly affects the overall combat performance indicators of UAVs. The limitations of the photoelectric load (that is, the photoelectric pod) are often required to be small in size, light in weight, high in technical indicators, and good in performance. For UAVs used in harsh environments (such as marine environm...

AI Technical Summary

Problems solved by technology

[0003] Some photoelectric pods on the market have the characteristics of long working distance and high stability and precision, but they often have large dimensions and weight, while some small and light photoelectric pods often have insufficient stability and high precision and long working distance. , or the structure and shape do not meet the requirements for use in military or harsh environments (such as marine environments)
