Description

Technical Field

[0001] The invention relates to the technical field of controllers, in particular to a Hall micro switch and a rocker controller. Background Art

[0002] The function of the joystick is to generate and output motion control signals through the shaking direction of the joystick, which is used to control the movement of external devices. It is widely used in amusement equipment, industrial equipment and other fields.

[0003] A traditional joystick controller generally includes a base and a joystick. The joystick is inserted into the base and can be shaken arbitrarily 360° in a circumferential direction relative to the base. Four mechanical micro switches are arranged around the joystick in the base in the four directions of southeast, northwest, and northeast. The movement direction of the external device is controlled by shaking the joystick to trigger the micro switches. This type of joystick controller has a simple and compact structure, is easy to operate, and has good working stability. However, this type of joystick controller has the following disadvantages: since a mechanical contact micro switch is used, each micro switch has only two states, namely, on or off. Therefore, although the joystick can be shaken arbitrarily 360° in a circumferential direction, it can only output motion control signals in eight fixed angle directions, namely, east, south, west, north, southeast, southwest, northwest, and northeast. Therefore, it is impossible to achieve fine control in any direction according to the arbitrary shaking angle of the joystick. In addition, it is impossible to control the movement speed of the external device according to the shaking amplitude of the joystick. Moreover, after long-term use, the switch contacts of the mechanical contact micro switch will have metal oxidation, which is prone to poor contact, so the service life is short. Summary of the invention

[0004] In order to overcome the defects existing in the prior art, the task of the present invention is to provide a Hall micro switch and a rocker controller, which can not only realize fine control in any direction according to any shaking angle of the rocker, but also control the moving speed of the external device according to the shaking amplitude of the rocker, and has a compact structure, and the overall structural size is basically consistent with the traditional rocker controller, which is convenient for directly replacing the traditional rocker controller and has good adaptability.
