Description

Technical Field

[0001] The present invention relates to the technical field of potentiometers, and in particular to a split electromagnetic induction rocker potentiometer. Background Art

[0002] The joystick potentiometer is a variable potentiometer suitable for the joystick control handle of game consoles, drones, etc. By shaking the joystick potentiometer, the state changes of related internal components of the game console, drone, etc. can be controlled.

[0003] Referring to Chinese patent document CN222190385U, in the prior art, an electromagnetic induction rocker potentiometer typically includes a rocker mechanism assembly and a magnetic induction circuit board. Both the rocker mechanism assembly and the magnetic induction circuit board are integrated structures, that is, the magnetic induction circuit board is installed within the rocker mechanism assembly, and the two are integrated into one. The rocker mechanism assembly is provided with a permanent magnet, and the magnetic induction circuit board is provided with a magnetic induction chip (e.g., a Hall chip). The permanent magnet and the magnetic induction chip cooperate with each other through magnetic induction. Under the push of the rocker mechanism assembly, the permanent magnet can be driven to move. During this process, the magnetic induction chip can sense the changes in the magnetic field of the permanent magnet and output a corresponding electrical signal.

[0004] However, this combined electromagnetic induction joystick potentiometer still has the following technical problems: when manufacturers manufacture the joystick control handle, they need to design both the handle circuit board and the magnetic induction circuit board; the magnetic induction chip and other related electronic components cannot be soldered onto the handle circuit board through the SMT process, but instead need to independently manufacture the magnetic induction circuit board and solder the magnetic induction chip and other electronic components onto the magnetic induction circuit board through the SMT process; in this way, on the one hand, the manufacturer needs to design and manufacture two circuit boards, namely the handle circuit board and the magnetic induction circuit board, which has a high manufacturing cost; on the other hand, the assembly and testing process of installing the magnetic induction circuit board in the joystick mechanism component is relatively cumbersome, and the assembly and testing costs are also relatively high.
