The first rocker arm and the second rocker arm 30 rotate along the tilting of the operating body 20, and the rotation axis of the first rocker arm and the rotation axis of the second rocker arm are perpendicular to each other. The sliding signal detection module 40 respectively detects the rotation of the first rocker arm and the second rocker arm 30. The pressing plate 50 is disk-shaped, and the center of the pressing plate 50 is provided with an open hole. One end of the elastic member 60 squeezes the upper part of the pressing plate 50 against the lower part of the operating body 20, and the other end of the elastic member 60 squeezes the bottom surface of the inner cavity 11 to reset the operating body 20 to the neutral position. The circuit board 70 is provided below the cover 10, and the surface of the circuit board 70 is provided with a touch-sensing pin 71. The seat 80 fixes the cover 10, the operating body 20 is made of conductive material, and the end of the operating body 20 in the inner cavity 11 is electrically connected to the touch-sensing pin 71.

(13) The multi-directional signal input detection apparatus 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 pressing plate 50, an elastic member 60, a circuit board 70 and a seat 80.

One end of the elastic member 60 is abutted against the other end of the operating body 20, and the other end of the elastic member 60 is electrically connected to the touch-sensing pin 71.

(14) When the user's hand touches the rocker, 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 sense contacts the operating body 20. Since the elastic member 60 is electrically connected to the touch-sensing pin 71, that is, the operating body 20 communicates the pressing plate 50 and the elastic member 60 to the touch-sensing pin 71. The operating body 20 is touched and inducted to trigger the touch-sensing pin 71. The multi-directional input detection device 1 receives the information that the user's hand touches the rocker, thereby enabling display or interaction function. That is, the signal induction path flows from the operating body 20 to the elastic member 60, and then flows to the touch-sensing pin 71 to be communicated with the external host, so as to realize signal interaction. When the user's hand leaves the rocker, the operating body 20 loses induction and cannot trigger the touch-sensing pin 71. The multi-directional signal input detection apparatus 1 receives the information that the user's hand leaves the rocker.

(15) The material of the operating body 20 can be conductive plastic, conductive metal, conductive rubber, etc. In this embodiment, the operating body 20 is the conductive rubber.

Conducting electricity through the coating medium, the operating body 20 can also achieve the effect of conductive induction.

(16) The pressing plate 50 can, on the one hand, connect the elastic member 60 and the operating body 20, which satisfies the stability of the connection between the elastic member 60 and the operating body 20, thereby ensuring the stability of the conduction; on the other hand, the pressing plate 50 maintains the flatness of the connection surface of the two connections, which ensures that the elastic member 60 can adapt to the swing and rotation of the operating body 20, and the induction effect of the circuit board 70 and the rotating assembly on the operating body 20 is accurately controlled.

(17) The multi-directional signal input detection apparatus 1 in the technical solution of the present application includes a cover 10, an operating body 20, a first rocker arm and second rocker arm 30, a sliding signal detection module 40, a pressing plate 50, an elastic member 60, a circuit board 70 and a seat 80.

When the user's hand touches the rocker, since the operating body 20 is a conductor, and the pressing plate 50 and the elastic member 60 connected to the operating body 20 are also conductors, then the hand senses contact with the operating body 20. Since the elastic member 60 is electrically connected to the touch-sensing pin 71, that is, the operating body 20 communicates the elastic member 60 to the touch-sensing pin 71. The operating body 20 is touched and inducted to trigger the touch-sensing pin 71, and the multi-directional signal input detection apparatus 1 receives the information that the user's hand touches the rocker, so as to realize the display or interaction function.

(19) In this embodiment, since the seat 80 is a conductor, and the seat 80 is electrically connected to the external host, the signal communication and transmission can be realized through the seat 80 and the external host. The signal induction path flows from the operating body 20 to the elastic member 60, then to the seat 80. The seat 80 is communicated with the external host to achieve signal interaction.
