AI Technical Summary
Given the limited space in the vehicle-mounted antenna compartment, existing technologies struggle to design dual-directional antenna mounts without increasing height, resulting in reduced vehicle platform mobility and a poor user experience.
Design a dual-axis antenna mount that utilizes vertical space and achieves independent tracking of the antenna mount through the engagement of anti-rotation shafts and cross splines. The mount includes antenna mounts A and B, which respectively contain an azimuth base, a turntable bearing, an elevation housing, an azimuth drive unit, and a combined slip ring. Azimuth movement is achieved through gear meshing.
Without increasing altitude, independent tracking of the two antenna mounts was achieved, improving the mobility of the vehicle platform and the user experience, and providing high-precision dual-target tracking capability for UAV telemetry and control systems.
