SINGLE-AXIS PROPORTIONAL JOYSTICK Russian patent published in 2022 - IPC G01B7/30 H01H21/00 

FIELD: control units.

SUBSTANCE: invention relates to joysticks based on the use of a magnetically controlled sensor, and is intended for precise control of the movement of actuators in mechanical engineering. The single-axis proportional joystick contains a base, a handle mounted on the base by means of a cylindrical hinge consisting of a semi-cylindrical upper part of the base, a hinged fork of the lower part of the handle and a pin fixed between them. The spring element, which is a torsion spring, is mounted on a pin in the cavity of the upper part of the base with the output of the support ends into the handle. The magnetically controlled sensor is located at the base, in the magnetic field zone of a two-pole permanent magnet placed in the handle, having a diametric magnetization along its side surfaces and made in the form of a volumetric annular sector with a constant cross-section along its entire length.

EFFECT: increase in the accuracy of regulating the output signal and preserving it during operation, obtaining a linear characteristic of the output signal, simplifying the design.
