Description

Practical electromagnetic rocker sensor and control device

Technical Field

The utility model relates to the technical field of novel sensors, in particular to a practical electromagnetic rocker sensor and a control device.

Background

A rocker sensor is one of the sensors, often used as a drone handle, gamepad, etc. The rocker sensor mainly comprises a rocker and two rocker assemblies, and the rocker is stirred to drive the rocker assemblies to operate, so that the potential adjusting module can output specific resistance or voltage.

The existing rocker sensor mainly has two types, one type is composed of an electric brush, a circuit board, a carbon resistor arranged on the circuit board and the like, the electric brush moves on the carbon resistor through external force to generate different resistance values on the circuit board, and then the electric signals generated by the different resistance values are different to achieve the effect of utilizing the rocker sensor to control the direction.

For example, chinese patent CN108269662A discloses a 3D rocker potentiometer, which comprises a housing, a rocking handle, a lower rocker arm and a plastic disc disposed in the housing, a rotary glue piece and a carbon piece disposed outside the housing, wherein two sides of the rotary glue piece are respectively fixed to the lower rocker arm and the carbon piece, a brush is disposed on the rotary glue piece, a carbon film layer and a terminal are disposed on the carbon piece, and the terminal and the brush are connected to the carbon film layer. When the carbon sheet resistance changing device is used, the rocking handle drives the lower rocking arm and the plastic disc to synchronously swing to drive the rubber rotating sheet to rotate, so that the brush on the rubber rotating sheet rotates on the carbon sheet, and the resistance value change is realized. However, the following disadvantages are common to this method of contact regulation by brushes and carbon resistances: if the metal with larger elasticity is used as the electric brush, the electric brush is quickly worn and has short service life, and if the metal with smaller elasticity is used as the electric brush, the problems of poor contact and failure easily occur between the electric brush and the carbon resistor; if the high-hardness carbon resistor is used, the electric brush is quickly abraded, large electric noise can be generated, if the low-hardness carbon resistor is used, carbon powder on the carbon resistor can be quickly abraded by the electric brush, the carbon powder can be stuck on the electric brush, the electric performance of the electric brush is affected, and the potentiometer has the problem of abnormal function. Therefore, the potentiometer has the defects of short service life and poor performance.

The other type is a magnetic induction potentiometer which is composed of a Hall element and a magnet arranged on a rocker or a rocker arm, wherein the Hall element detects the movement of the magnet on the rocker or the rocker arm and outputs different voltage values, so that the effect of controlling the direction by using the rocker potentiometer is achieved.

For example, chinese patent CN202423092U discloses a magneto-electric rocker for a non-contact game machine, which includes a control rod, an upper rocker arm and a lower rocker arm, wherein one end or both ends of the upper rocker arm are fixedly provided with a permanent magnet, one end or both ends of the lower rocker arm are fixedly provided with a permanent magnet, a magneto-sensitive IC chip for sensing the position change of the permanent magnet is disposed near each permanent magnet, when the control rod swings, the permanent magnet on the upper rocker arm or the lower rocker arm and the magneto-sensitive IC chip perform relative rotation, and the magneto-sensitive IC chip outputs different voltage values by detecting the rotation position change. However, the following drawbacks are common to the above-described method of detecting a rotational position change caused by the rotation of the permanent magnet on the upper rocker arm or the lower rocker arm around the rotational axis (structural center line) by the magnetic sensor IC chip: at present, due to the backward production process of magnetic materials in China, the central axis of a magnetic line between two magnetic poles of produced magnetic steel has larger deviation with the structural central line of the magnetic steel, so that the change of the rotation position detected by a magnetic sensitive IC chip has larger deviation, the control precision of the rocker potentiometer is low, the actual application can not be carried out at all, and the magnetic induction type rocker potentiometer can not be produced.
