Spherical sealing type two-dimensional degree-of-freedom operating rod and operating method

Abstract

A spherical sealing type two-dimensional degree-of-freedom operating lever comprises a shell, and a metal spherical surface sealing mechanism, an X-axis rotating mechanism, a Y-axis rotating mechanismand an angle sensor used for detecting angle position information of the X-axis rotating mechanism and the Y-axis rotating mechanism are installed on the shell. The metal spherical surface sealing mechanism comprises a metal spherical surface connecting rod used for being fixedly installed on a panel on the shell, one end of the metal spherical surface connecting rod is a hollow hemispheroid, andthe hemispheroid is installed on the panel through a sealing bush and a sealing ring; an inner rotating frame used for being matched with the metal spherical surface sealing mechanism and a base usedfor being matched with the X-axis rotating mechanism and the Y-axis rotating mechanism are installed in the shell, and a switching rotating shaft is fixedly connected to the metal spherical surface connecting rod and rotationally installed on the inner rotating frame. The operating lever is reasonable in design, capable of effectively reducing zero-position shaking, safe, reliable, long in service life, resistant to mould and solar radiation and capable of being suitable for various severe environments through a metal spherical surface sealing mode.

Description

technical field [0001] The invention relates to the technical field of joysticks, in particular to a spherically sealed two-dimensional freedom degree joystick, and also to a method for operating the spherically sealed two-dimensional degree of freedom joystick. Background technique [0002] At present, most joysticks need rubber dustproof covers for dustproof and waterproof, and joysticks that do not use rubber dustproof covers also sacrifice part of the performance of dustproof and waterproof. However, the rubber dust cover has problems such as easy aging and damage, and the electromagnetic protection performance of the rubber dust cover is low, and there are natural defects in the anti-mold solar radiation; and the joystick without the rubber dust cover is Dustproof and waterproof performance is insufficient. And the current joystick adopts the life-span reliability of extension spring form lower. [0003] Therefore, there is a need for a joystick that can solve the def...
