Problems solved by technology

However, the traditional joystick is large in size, bulky, and powerful in operation. It is suitable for the operation of heavy equipment in a large space, but cannot meet the needs of small spaces and light servo mechanisms for miniaturized joysticks.
[0003] The existing published unlicensed Chinese patent document CN 103345311A discloses a joystick with a sensing device, which mainly solves the problem that the joystick is used for a general-purpose vehicle. In its neutral position or a position near it, the movable part performs Larger angular motions with only a small change in detected magnetic flux, resulting in poor angular resolution, which can compromise the safety of joystick-mounted applications such as vehicles, while increasing product cost

Embodiment Construction

[0015] Such as figure 1 A miniature joystick based on a Hall sensor as shown includes a base 1, and the inside of the base 1 is provided with a Hall sensor 2 and a circuit board 3, and the Hall sensor 2 is arranged above the circuit board 3. Above the base 1 is a reset structure 4, above the reset structure 4 is provided a dustproof cover 5, and the top of the dustproof cover 5 is an operation cap 6 for manipulation by fingers.

[0016] As a preferred technical solution of the present invention, the insulation withstand voltage of the Hall sensor 2 is 3KV.

[0017] Further, the joystick can realize the manipulation of the operation cap 6 by the thumb.

[0018] Further, the joystick is suitable for the operation needs of light servo mechanisms.

[0019] The working principle of the present invention is:

[0020] Operate on the operation cap 6 with the thumb, transmit the corresponding command to the Hall sensor 2, and act on the circuit board 3 through the magnetic field ins...

Abstract

The invention relates to a miniature operating lever based on a Hall sensor. The miniature operating lever comprises a base, wherein a Hall sensor and a circuit board are arranged in the base; the Hall sensor is arranged above the circuit board; a reset structure is arranged above the base; a dustproof sleeve is arranged above the reset structure; and an operation cap is arranged at the top of thedustproof sleeve and used for being operated and controlled through fingers. The miniature operating lever has the advantages that the miniature operating lever is realized by adopting the Hall sensor, can be controlled by a thumb, is high in precision, good in linearity and wide in bandwidth, has relatively strong external magnetic field interference resistance, and meets the requirement of operation in a small-size space.

Description

technical field [0001] The invention relates to the field of joysticks, in particular to a miniature joystick based on Hall sensors. Background technique [0002] The basic principle of a joystick is to convert the movement of a plastic rod into electronic information that a computer can process. This basic design consists of a joystick resting on a plastic base with a resilient rubber casing. There is a circuit board in the base just below the joystick. A circuit board consists of some "printed wires" and these wires are connected to several contact points. From these contacts, then, lead regular wires to the computer. However, the traditional joystick is large in size, bulky, and powerful in operation, which is suitable for operating heavy equipment in a large space, but cannot meet the needs of small spaces and light servo mechanisms for miniaturized joysticks. [0003] The existing published unlicensed Chinese patent document CN 103345311A discloses a joystick with a...
