An Arbitrarily Parked Spherical Two-Dimensional Freedom Joystick and Its Manipulation Method

Abstract

A joystick with arbitrary parking type spherical surface two-dimensional degree of freedom and a manipulation method thereof, comprising a joystick handle and a manipulation mechanism installed at the bottom end of the joystick handle, the manipulation mechanism is provided with a casing, and the casing is provided with an opening for the movement of the joystick handle, and the opening is A spherical sealing mechanism is installed at the center, and the X-axis steering mechanism and the Y-axis steering mechanism are installed in the housing; the X-axis steering mechanism is equipped with an X-axis damper that enables the joystick to stop at any position in the X-axis, and the X-axis shaft is equipped with The X-axis protrusion matched with the X-axis damper, the Y-axis steering mechanism is equipped with a Y-axis damper that enables the joystick to stop at any position in the Y-axis, and the Y-axis shaft is equipped with a Y-axis protrusion that cooperates with the Y-axis damper rise. The invention adopts a lockable friction damper, which not only ensures the adjustability of the damping force, but also satisfies the reliable maintenance of the damping force in a strong vibration environment; the spherical sealing mechanism is used to realize the dustproof and waterproof of the shell, and the Intrusion protection of tiny particles of foreign matter and dust.

Description

Technical field [0001] The present invention belongs to the field of joystick design, and in particular, the present invention relates to an arbitrary stationary spherical two-dimensional freedom joystick and a manipulation method. Background technique [0002] The restock implementation of any resident joystick now is mainly frictional damper, damping lipid damper, electromagnetic damper, etc., the most applied to the frictional damper. The realization of the frictional damper is relatively simple, but the existing friction damper is poorly tolerated in the vibration environment, it is difficult to ensure the reliable maintenance of the damping force in the stiff vibration environment. . At present, most resident joysticks use gap dust measures to poor the protection of small particulate matter. Inventive content [0003] The technical problem to be solved in the present invention is aimed at any resident spherical two-dimensional freedom joystick, a structure reasonable, high ...

AI Technical Summary

Problems solved by technology

The implementation structure of the friction damper is relatively simple, but the existing friction damper has poor tolerance to the vibration environment, and it is difficult to ensure the reliable maintenance of the damping force under the condition of satisfying the damping force adjustability in the severe vibration environment

At present, most of the arbitrary parking joysticks adopt gap-type dust-proof measures, and the protection effect on small particles of foreign matter is poor.
