Description

Technical field:

[0001] The utility model relates to the technical field of photoelectric pod production and manufacturing, in particular to a three-axis photoelectric pod rotating device which has a reasonable structure, stable rotation, can avoid cable breaking during rotation, and is easy to assemble. Background technology:

[0002] An optoelectronic pod is a crucial component of optoelectronic reconnaissance and detection equipment, typically mounted on a detection vehicle (such as a drone). When the detection vehicle reaches a designated position, the pod's motor controls the orientation of its internal optoelectronic equipment, enabling detection or reconnaissance of the target. To meet the needs of drones performing reconnaissance and strike missions, optoelectronic pods must be equipped with various optoelectronic payloads, such as visible light cameras, infrared thermal imagers, and laser rangefinders.

[0003] Patent document CN202311633491.9 mentions a three-axis optoelectronic pod. The fixing method of its rotating mechanism is complex in structure and inconvenient to assemble. Too many screws are used in the wire buckle positions. When the drone is flying with the pod suspended, there is a risk of screws falling off and deforming. When rotating, the cable storage space is limited, which can easily cause the cable to be broken due to stress. Summary of the invention:

[0004] In response to the problems in the prior art that the rotation mechanism of traditional optoelectronic pods is inconvenient to assemble or store wires, the utility model proposes a three-axis optoelectronic pod rotation device with a reasonable structure, stable rotation, the ability to avoid cable breakage during rotation, and easy assembly.
