In order to explain in detail the technical content, structural features, purpose and effect of the creative joystick structure 100, the following examples are given and explained in detail with drawings.

As shown in the first and second figures, the creative joystick structure 100 includes a keycap 1, a wire 2, a base 3, a pointing stick unit 4 and a circuit board 5. One end of the wire 2 is fixed in the keycap 1, and the other end of the wire 2 is connected to the circuit board 5. The base 3 is arranged on the lower surface of the keycap 1, the pointing stick unit 4 is arranged on the lower surface of the base 3, and the pointing stick unit 4 is arranged on the upper surface of the circuit board 5. In this embodiment, the keycap 1 and the wire 2 are made by injection molding to form a whole, which simplifies the assembly process of the creative joystick structure 100 and reduces the manufacturing cost of the creative joystick structure 100.

Please refer to the third to sixth figures, the key cap 1 is provided with a head 11, a fixing portion 12 and a first positioning hole 13. The fixing portion 12 is formed by extending downward from the middle of the lower surface of the head 11. One end of the wire 2 is integrally formed in the fixing portion 12. In specific implementation, one end of the wire 2 extends into the head 11. The fixing portion 12 is arranged in the corresponding mechanism of the base 3. The key cap 1 is provided with the first positioning hole 13 penetrating the lower surface of the fixing portion 12. The top end of the pointing rod unit 4 is fixed in the first positioning hole 13 to realize the positioning and fixing of the pointing rod unit 4 and the key cap 1. The key cap 1 is made of conductive soft plastic so that the head 11 and the fixing portion 12 of the key cap 1 have conductive ability. Thus, when a finger touches the keycap 1, the circuit board 5 can detect changes in the electrical characteristics of the keycap 1, such as changes in capacitance value, through the wire 2.

The base 3 is a hollow cylindrical body, and the base 3 is provided with a base 30, a covering portion 31, a connecting portion 32, a second positioning hole 33 and a through hole 34. The base 30 extends upward to form a hollow covering portion 31. The fixing portion 12 of the key cap 1 is arranged in the covering portion 31. The connecting portion 32 is formed at the connection between the base 30 and the covering portion 31. The bottom surface of the fixing portion 12 of the key cap 1 abuts against the upper surface of the connecting portion 32. The base 3 is provided with the second positioning hole 33 penetrating the upper and lower surfaces of the connecting portion 32. The second positioning hole 33 corresponds to the first positioning hole 13 of the key cap 1. The top of the pointing rod unit 4 passes through the second positioning hole 33 and is fixed to the first positioning hole 13 of the key cap 1 to achieve positioning and fixing of the pointing rod unit 4, the base 3 and the key cap 1. The base 3 is provided with the through hole 34 that passes through the upper and lower surfaces of the connecting portion 32. The through hole 34 is formed on one side of the second positioning hole 33. The wire 2 passes through the through hole 34 and is connected to the circuit board 5.

When the creative joystick structure 100 is assembled, first, the key cap 1 and the wire 2 are injection molded together. Then, the base 3 assembles the key cap 1. Next, the key cap 1 and the base 3 are assembled on the top of the pointing stick unit 4, the bottom of the pointing stick unit 4 is welded to the upper surface of the circuit board 5, and the wire 2 is electrically connected to the circuit board 5.

In summary, the key cap 1 and the wire 2 of the creative joystick structure 100 are made by injection molding to form an integral body, and the key cap 1 is made of conductive soft plastic, so that the head 11 and the fixing part 12 of the key cap 1 have conductive ability, simplifying the assembly process of the creative joystick structure 100, and reducing the manufacturing cost of the creative joystick structure 100. Therefore, the creative joystick structure 100 can simplify the assembly process and reduce the manufacturing cost.
