Description

Technical Field

[0001] The utility model relates to the technical field of industrial Hall rocker, in particular to a joystick structure with a Hall circuit board which is easy to install. Background Art

[0002] The Chinese patent authorization announcement number is CN 217954992 U, and the authorization announcement date is December 2, 2022. It discloses a control handle, a remote control and an operating machine, including a housing, a joystick, a magnet, a Hall sensor and a reset assembly. The joystick is rotatably connected to the housing, and the control end is located in the housing. The magnet is arranged at the end of the control end. The Hall sensor is arranged on the inner side of the housing and is located between the magnet and the housing. When the joystick is in the middle position, the Hall voltage output by the Hall sensor is the smallest. The reset assembly is used to drive the joystick back to the middle position. When the joystick drives the magnet to swing, the Hall voltage output by the Hall sensor becomes larger, thereby controlling the corresponding mechanical device action. The control handle provided by the utility model controls the movement of the mechanical device contactlessly by means of an induction magnetic field, which solves the problem that the control components using the contact trigger method in the prior art are worn out for a long time, resulting in reduced reliability and waterproof and dustproof properties. The defects of the prior art are that the cover plate, the first housing and the second housing are fixedly connected by screws, the assembly method is relatively complicated, and there will be looseness after long-term use, which affects the use effect; in view of this situation, it is urgent to improve.
