Joystick Controller

Abstract

A joystick controller includes a printed circuit board defining a plurality of pads thereon, a restraining assembly fastened above the printed circuit board, a switch button slidably mounted onto the restraining assembly with a locking post stretching into the restraining assembly, and a connecting member slidably mounted between the restraining assembly and the printed circuit board and further restrained by the restraining assembly. The connecting member has a base board, a plurality of contact portions protruded under the base board, and a locking axle protruded on the base board. The locking axle is inserted into the restraining assembly and then locked to a bottom end of the locking post so that the connecting member can be driven to slide in a restrained range by the restraining assembly through smoothly pushing the switch button so as to make the contact portions electrically contact the corresponding pads of the printed circuit board.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a signal input device for an electronic product, and more particularly to a joystick controller adapted for a notebook computer, a mobile phone, a video game and the like.[0003]2. The Related Art[0004]At present, joystick controllers have been widely used in electronic products, such as notebook computers, mobile phones and video games, to control the movement of a cursor or an image on a monitor. A conventional joystick controller generally includes a shell which is used to receive electronic and mechanical parts therein, and a lever mounted in the shell with a top end thereof stretching out of the shell. There is a sensor disposed on a bottom of the joystick controller. In use, the lever is firstly shaken at a certain angle, and then the sensor senses a shake displacement of the lever and further transforms the shake displacement into a corresponding displacement signal so as to contro...

Benefits of technology

[0006]An object of the present invention is to provide a joystick controller. The joystick controller includes a printed circuit board which defines a plurality of pads thereon spaced from one another, a restraining assembly fastened above the printed circuit board, a switch button slidably mounted onto the restraining assembly with a locking post stretching into the restraining assembly, and a connecting member which is slidably mounted between the restraining assembly and the printed circuit board and further restrained by the restraining assembly. The connecting member has a base board, a plurality of contact portions protruded under the base board and spaced from one another, and a locking axle protruded on the base board. The locking axle is inserted into the restraining assembly and then locked to a bottom end of the locking post of the switch button so that the connecting member can be driven to slide in a restrained range by the restraining assembly through smoothly pushing the switch button so as to make the contact portions electrically contact the corresponding pads of the printed circuit board.

[0007]As described above, the joystick controller of the present invention can achieve many kinds of connections between the contact portions of the connecting member and the pads of the printed circuit board by means of smoothly pushing the switch button to drive the connecting member to slide in the restrained range by the restraining assembly on the printed circuit board, instead of shaking a lever in the prior art. So the joystick controller has a longer use life. Furthermore, the movement of the cursor or image on the monitor is controlled by means of the contact portions contacting the corresponding pads, instead of a sensor sensing a shake displacement of the lever in the prior art. Therefore, the joystick controller can achieve a more sensitive and reliable controlling to the movement of the cursor or image on the monitor.

Problems solved by technology

As a result, the tiny lever is apt to be damaged under the repeated shaking that shortens the use life of the joystick controller.

Furthermore, a slight shake displacement may happen when the tiny lever is shaken.

As a result, it causes that the slight shake displacement may not be sensed by the sensor or is sensed by the sensor with a bias.

As a result, the conventional joystick controller has an insensitive controlling to the movement of the cursor or the image on the monitor.
