Abstract
Description
Technical Field

[0002] With the widespread application of drones in fields such as aerial photography, agricultural monitoring, industrial inspection, and emergency rescue, the performance requirements for gimbals are increasing.
[0003] Existing industrial drone gimbals are generally three-light gimbals, which contain thermal imaging, laser, and visible light core modules. During the operation of these three modules, a lot of heat is generated. Due to the small size, light weight, and compact structure of drone gimbals, the heat is often difficult to dissipate. High heat accumulation can cause a decrease in core performance or even loss of function. Although some gimbals can be equipped with fans to cool the system, the rotation of the fans will increase the vibration of the gimbal, affecting the stability of the gimbal's image or increasing the difficulty and cost of the equipment's algorithm design.
[0004] In certain special situations, such as strong electromagnetic fields with high voltage, high-precision aerial photography, military and petrochemical areas, gimbals need to have electromagnetic interference protection capabilities.
