The rotational movements of the first rocker arm and the second rocker arm 30 are detected separately; the pressure plate 50 is disc-shaped, and an opening is provided in the center of the pressure plate 50; one end of the elastic member 60 presses the upper surface of the pressure plate 50 against the lower part of the operating body 20, and the other end of the elastic member 60 presses the bottom surface of the inner cavity 11, so that the operating body 20 is reset to the neutral position; the circuit board 70 is arranged under the cover 10, and the surface of the circuit board 70 is provided with a sensing pin 71; the base 80 fixes the cover 10: the operating body 20 is made of conductive material, and the end of the operating body 20 located in the inner cavity 11 is electrically connected to the sensing pin 71.

[0041] The multi-directional signal input detection device 1 includes a cover 10, an operating body 20, a first rocker arm and a second rocker arm 30, a sliding signal detection module 40, a pressure plate 50, an elastic member 60, a circuit board 70 and a base 80; the cover 10 has an inner cavity 11 and an opening 13 connected to the inner cavity 11, the circuit board 70 is arranged on a side wall of the inner cavity 11 opposite to the opening 13, and a sensing pin 71 is arranged on the surface of the circuit board 70 facing the opening 13. The operating body 20 and the elastic member 60 are both made of conductive materials, and the side wall of the operating body 20 is connected to the first rocker arm and the second rocker arm 30. One end of the operating body 20 is arranged in the inner cavity 11, and the other end extends outside the opening 13.

[0042] When the user's hand touches the joystick, since the operating body 20 is a conductor, the elastic member 60 connected to the operating body 20 is also a conductor, and the hand senses the contact with the operating body 20. Since the elastic member 60 is electrically connected to the sensing pin 71, that is, the operating body 20 connects the pressure plate 50 and the elastic member 60 to the sensing pin 71, the touch sensing operating body 20 further triggers the sensing pin 71, and the multi-directional input detection device 1 receives the information that the user's hand touches the joystick, and can then realize the display or interactive function. That is, the signal sensing path is from the operating body 20 to the elastic member 60, and then to the sensing pin 71, and is connected to the external host through the sensing pin 71 to realize signal interaction. When the user's hand leaves the joystick, the operating body 20 loses the sensing and cannot trigger the sensing pin 71, and the multi-directional signal input detection device 1 receives the information that the user's hand leaves the joystick.

One end of the elastic member 60 squeezes the upper surface of the pressure plate 50 against the lower part of the operating body 20, and the other end of the elastic member 60 is electrically connected to the sensing pin 71 provided on the circuit board 70. When the user's hand touches the joystick, since the operating body 20 is a conductor, the pressure plate 50 and the elastic member 60 connected to the operating body 20 are also conductors, and the hand senses the contact with the operating body 20. Since the elastic member 60 is electrically connected to the sensing pin 71, that is, the operating body 20 connects the elastic member 60 to the sensing pin 71, the touch sensing operating body 20 further triggers the sensing pin 71, and the multi-directional signal input detection device 1 receives the information that the user's hand touches the joystick, thereby realizing the display or interactive function.
