BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention generally relates to a joystick module, and more particularly to a joystick module having a steering stick unit which is able to be quickly assembled to the joystick module to be applied in a game controller, and is able to be disassembled from the joystick module simply and quickly.

2. The Related Art

In order to increase a function and an operation feeling of a game controller, the game controller generally uses a design that a pressing switch is integrated into a steering stick unit of a joystick module of the game controller. In order to make the steering stick unit and the pressing switch operated at the same time without a mutual interference. A structure that integrates the steering stick unit with the pressing switch has become a focus in a joystick module design.

A conventional game joystick switch includes a joystick module. The joystick module includes a steering stick unit, a shell and a pressing switch. The steering stick unit is rockable and is disposed in the shell. The steering stick unit has a contacting portion. The contacting portion protrudes out of the shell. When a user presses the steering stick unit, the pressing switch is pressed through the contacting portion.

A conventional integrated handle joystick with a hall element includes a joystick module. The joystick module includes a steering stick unit and a base. The steering stick unit is rockable, and the steering stick unit is disposed in the base. A part of the steering stick unit protrudes out of the base to press a pressing switch.

However, the above-mentioned joystick module may integrate the steering stick unit and the pressing switch, and the steering stick unit and the pressing switch are integrally soldered to a circuit board. The aforesaid structure design has following deficiencies in an application. A usage life of the steering stick unit is less than a usage life of the pressing switch. When the steering stick unit is broken down, the steering stick unit is changed together with intact parts which are the pressing switch, a substrate, etc. So a waste is caused. Furthermore, when the user wants to change the steering stick unit voluntarily from the joystick module, the user need use a desoldering device to disassemble the whole joystick module from the game controller, so that a new joystick module is assembled to the game controller. Nonetheless, in the desoldering process, if the user has a slight carelessness, a damage of the whole game controller is caused. In addition, the discarded circuit boards and electronic components of the game controller usually have large amounts of harmful substances, such as heavy metals. If the discarded circuit boards and the electronic components are abandoned at will, an environmental pollution is caused. Besides, a small amount of harmful gases will be produced in the desoldering process, although the small amount of the harmful gases is nonlethal, a human health is still affected after a long time use.

Thus, it is essential to provide an innovative joystick module having a steering stick unit which is able to be quickly assembled to the innovative joystick module to be applied in a game controller, and is able to be disassembled from the innovative joystick module simply and quickly. In addition, a user changes the innovative joystick module directly without using a desoldering tool.
