Description

[Technical field]

[0001] The present invention relates to the field of joystick switch technology, and in particular to a hole joystick structure. [Background technology]

[0002] With the improvement of living standards, people's hobby activities are becoming more and more abundant, and electronic game machines that combine leisure entertainment, intellectual development, EQ improvement, and even exercise fitness have been favored by the masses. As an important component of an electronic game machine, the joystick switch of a game handle is an important part for people to experience electronic games. In the prior art, a joystick switch of a game handle generally includes a housing, a first interlocking part that is mounted on the housing and rotatably attached to the housing, a second interlocking part that extends along a direction perpendicular to the vertical direction of the first interlocking part and is mounted on the housing and rotatably attached to the housing, a joystick that can be tilted and whose tip protrudes outside the housing, a stick holder that can move along the joystick axis direction, and a base that is provided at the bottom of the housing. A reset spring is usually provided between the joystick and the stick holder, and the reset spring is used for resetting the joystick, and an electric component is attached to the housing. Such a game joystick switch has the following disadvantages. Since the electrical components are attached to the housing and located outside the case, the electrical components protrude greatly as a whole, making the product large in size and hindering the development of product integration. In addition, the number of parts is large, the structure is complicated, and the assembly efficiency of the production line is low. Furthermore, currently available game handles and the like refer to joysticks for control, and generally adopt a resistive film structure, which is simple in structure and low in cost, but because of the sliding variable resistor structure, metal or carbon brushes directly slide on the electrical resistive film to detect the position of the joystick, which has problems of short life, easy drift, and low accuracy. The trackball type Hall sensor calculates the position of the XY axis by using four Hall devices, but the multiple Hall devices have a high failure rate, high cost, and complicated calculation.
