Description

Technical Field

[0001] The utility model relates to the technical field of rocker potentiometers, and particularly relates to a rocker structure of a split-type electromagnetic induction rocker potentiometer. Background Art

[0002] A rocker potentiometer is a variable potentiometer applicable to rocker control handles of game consoles, drones, etc. Rocker potentiometers mainly include brush-type rocker potentiometers and electromagnetic induction rocker potentiometers. The brush-type rocker potentiometer adjusts the resistance value by shaking the rocker of the rocker potentiometer and then through the brush mechanism of the potentiometer, so as to control the state change of internal related components of game consoles, drones, etc. This kind of rocker potentiometer uses a carbon film or a resistance wire structure, and it is necessary for the brush contact to contact and rub on the carbon film to detect different positions of the potentiometer. It has the following deficiencies: (1) The wear life of the carbon film is short and the production error is large; (2) Due to the friction of the brush contact point, contact interference noise will be generated when the position changes.

[0003] An electromagnetic induction rocker potentiometer generally includes a rocker mechanism assembly and a magnetic induction circuit board. In the prior art, both the rocker mechanism assembly and the magnetic induction circuit board are of an integrated structure, that is, the magnetic induction circuit board is installed inside the rocker mechanism assembly, and the two are integrated; among them, the rocker mechanism assembly is provided with a permanent magnet, and the magnetic induction circuit board is provided with a Hall chip. The permanent magnet and the Hall chip are magnetically inductively cooperated. Under the pushing action of the rocker mechanism assembly, the permanent magnet can be driven to move. During this process, the Hall chip can sense the magnetic field change of the permanent magnet, and thus output a corresponding electrical signal.

[0004] However, the existing integrated electromagnetic induction rocker potentiometer still has the following technical problems: When manufacturers manufacture rocker control handles, they need to design both the main circuit board of the handle and the magnetic induction circuit board; related electronic components such as Hall chips cannot be soldered onto the main circuit board of the handle through the SMT process, but it is necessary to independently manufacture the magnetic induction circuit board and solder electronic components such as Hall chips and pins onto the magnetic induction circuit board through the SMT process; in this way, on the one hand, manufacturers need to design and manufacture two circuit boards, namely the main circuit board of the handle and the magnetic induction circuit board, and the manufacturing cost is relatively high; on the other hand, the assembly and testing processes of installing the magnetic induction circuit board in the rocker mechanism assembly are relatively cumbersome, and the assembly and testing costs are also relatively high. Summary of the Utility Model
