The threaded hole on the rotating shaft 5 should be aligned with the threaded through hole on the small slider 7, and fixed with the set screws.

[0064] In order to achieve the above technical effects, in the joystick with the torsion spring box reset structure of this embodiment, as Figures 1 to 8 As shown:

[0065] A hole is provided on the rocker 1, and a threading hole 1-1 is provided on the base 3, and the upper handle wire harness of the joystick rocker 1 is passed through the hole 1-1 and the threading hole 2-1.

[0066] The installation implementation method of this embodiment is as follows:

[0067] First, the torsional spring box assembly 30 can be pre-assembled, the two torsional spring feet 402-1 of the torsional spring 402 are respectively clamped in the clamping slot 401-1 in the torsional spring box base 401, and the torsional spring 402 is installed in the circular ring gap in the torsional spring box 401. The torsional spring box cover plate 403 is fixed on the torsional spring box 401 using the three M2.5 screws at the top left, bottom left, and top right, and the torsional spring 402 is limited.

[0068] When the torsional spring box assembly 30 is installed, the two torsional spring feet 402-1 of the torsional spring 402 need to be clamped on the clamping feet 901-1 of the small slider 7 or the large slider 9, and a certain amount of torsional spring pre-pressing is required to ensure that the torsional spring can fully guarantee the reset gap of the joystick with the torsional spring box reset structure in this embodiment. When installing the torsional spring box 4, two M3 screws are used to pass through the left and right through holes of the torsional spring 4 to fix the entire torsional spring box assembly 30 on the base 2. If a friction positioning type joystick needs to be made, a friction box can be used for module replacement installation.

[0069] For the groove 501 inside the shaft 5, glue is used to fix it first, and then the metal edge outside the groove 501 is flipped into the compressed magnetic steel.

[0070] For the assembly of the rocker 1, two knurled pins are used to press into the hole at the bottom of the rocker 1, and the rocker 1, the knurled pin, and the small slider 7 are tightly connected through knurling. The knurled pin and the small slider are in clearance fit.

[0071] For the main structure assembly of the base 2, the plastic shaft sleeve 6 is first pressed into the circular hole of the base 2 from the inside, then the large slider 9 is inserted into the inner cavity of the base 2 from bottom to top, and then the shaft 5 with the magnetic steel assembled is aligned with the circular hole of the base 2 and is assembled into the circular hole of the large slider 9. The threaded hole 502 on the shaft 5 needs to be aligned with the threaded hole on the large slider 9, and then M3 set screws are used to connect and install the two parts. Similarly, the small slider 7 with the rocker 1 installed is assembled in the same way in the two hole positions opposite to the large slider at 90 degrees, and the shaft 5 and M3 set screws are connected and fixed in the same way.

[0072] After the base 2 with the large and small sliders is assembled, the two torsional spring feet 402-1 of the torsional spring 402 are bent to the clamping feet 9-1 of the large and small sliders, respectively. After clamping, the joystick has a certain pre-pressing in the middle position to prevent the middle gap from being affected by shaking. The above completes the main rotating structure assembly.

[0073] M3 mechanical screws are used to fix the Hall potentiometer 8 on the base 2. When in use, the Hall potentiometer 8 needs to be software calibrated to confirm the output range value.

[0074] Finally, use three M4 machine screws to install the limit plate 3 on the base. The limit forms of the limit plate 3 include but are not limited to cross limit, circular limit, square limit, T-shaped limit, straight limit, etc. The above completes the main structure assembly of the joystick.

[0075] This joystick utility model describes only the main structure of the joystick. This main structure must be compatible with the appropriate joystick upper handle, the joystick's bottom PCB, and the bottom shell to form a complete product. The hole 1-1 on the joystick rocker 1 and the threading hole 2-1 on the base 2 are used to thread the wiring harness through the joystick upper handle.

[0076] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present invention, and in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present invention.
