AI Technical Summary

Technical Problem

Existing tilting mechanisms struggle to balance the linearity of servo displacement-tilt angle, self-locking of tilt angle, measurement and feedback, control accuracy, and structural strength within a 90° tilt angle range, all within limited space and weight constraints.

Method used

A linear tilt servo is used to drive the tilt base. Combined with an angle sensor, the motion relationship between the servo axis and the tilt axis is designed to achieve a tilt angle change of 0°-95°. An angle sensor is installed on the tilt axis for real-time feedback. The tilt servo interface is designed with hinged joints on both sides to withstand tensile and compressive loads. Aluminum alloy material is used to ensure structural strength.

Benefits of technology

It achieves linear change of tilt angle under small space and weight requirements, ensuring control accuracy and structural strength, providing real-time tilt angle feedback, and meeting multiple functional requirements of the tilting mechanism.
