[0031] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0032] Embodiment 1: As Figure 1 , Figure 2 and Figure 5As shown in the figure, a Hall potential module for a game steering wheel includes a housing 1, a PCB board 2, and a rotating shaft 3. The housing 1 includes a box body 101 and a box cover 102. The PCB board 2 is installed in the box body 101. A rotating shaft mounting hole 103 is provided on the box cover 102. The rotating shaft 3 is rotatably installed in the rotating shaft mounting hole 103. A bearing 4 is assembled between the rotating shaft 3 and the rotating shaft mounting hole 103 to make the rotation smoother. The rotating shaft 3 is located on one side of the PCB board 2. One end of the rotating shaft 3 facing the PCB board 2 is provided with a turntable 301. An eccentric magnet 5 is provided on the turntable 301. The magnet 5 makes a circular motion driven by the turntable 301. 4 (in other embodiments, it can also be 2, 8, 16, etc.) Hall sensors 6 cooperating with the magnet 5 are provided on the PCB board 2 and are evenly distributed on the circumference of a virtual circle. The virtual circle is coaxially arranged with the rotating shaft 3. The PCB board 2 is provided with a plug-in pin 7 connected to the main control circuit board.

[0033] Working principle: During assembly, the utility model is integrally inserted into the socket on the main control circuit board of the steering wheel through the plug-in pin 7. The rotating shaft 3 is docked with the main shaft of the steering wheel (the main shaft of the steering wheel can be provided with a return spring depending on the situation). The main shaft of the steering wheel drives the rotating shaft 3 to rotate together with the turntable, and then drives the magnet 5 to rotate. When the magnet 5 rotates in a circumferential motion, the magnet 5 passes through the 4 Hall sensors 6 in sequence. Each Hall sensor 6 sequentially senses the change in the magnetic field strength, thereby generating different Hall voltages. The Hall voltage changes with the change in the magnetic field strength. The stronger the magnetic field, the higher the voltage; the weaker the magnetic field, the lower the voltage. The magnetic field strength sensed by the 4 Hall sensors 6 is converted into Hall voltage signals and transmitted to the single-chip microcomputer of the main control PCB board of the game steering wheel for analysis. Thus, it is possible to judge actions such as the rotation direction, rotation angle, and rotation number of the steering wheel.

[0034] Embodiment 2: As Figure 3 , Figure 4 and Figure 5As shown in the figure, a Hall potential module for a game steering wheel includes a housing 1, a PCB board 2, and a rotating shaft 3. The housing 1 includes a box body 101 and a box cover 102. The PCB board 2 is installed in the box body 101. A rotating shaft mounting hole 103 is provided on the box cover 102. The rotating shaft 3 is rotatably installed in the rotating shaft mounting hole 103. A bearing 4 is assembled between the rotating shaft 3 and the rotating shaft mounting hole 103 to make the rotation smoother. The rotating shaft 3 is located on one side of the PCB board 2. One end of the rotating shaft 3 facing the PCB board 2 is provided with a turntable 301. There are 4 (which can also be 2, 8, 16, etc. in other embodiments) magnets 5 with gradually changing sizes on the turntable 301, and they are evenly distributed on the circumference of a virtual circle. The virtual circle is coaxially arranged with the rotating shaft 3. The magnets 5 make a circular motion driven by the turntable 301. An eccentric Hall sensor 6 cooperating with the magnets 5 is provided on the PCB board 2. The PCB board 2 is provided with a plug-in pin 7 connected to the main control circuit board.

[0035] Working principle: During assembly, the utility model is integrally plugged into the socket on the main control circuit board of the steering wheel through the plug-in pin 7. The rotating shaft 3 is docked with the main shaft of the steering wheel (the main shaft of the steering wheel can be provided with a return spring according to the situation). The main shaft of the steering wheel drives the rotating shaft 3 to rotate together with the turntable, and then drives the 4 magnets 5 to rotate. When the 4 magnets 5 rotate in a circumferential motion, each magnet 5 passes by the Hall sensor 6 in turn. The Hall sensor 6 sequentially senses the change in the magnetic field strength, thereby generating different Hall voltages. The Hall voltage changes with the change in the magnetic field strength. The stronger the magnetic field, the higher the voltage; the weaker the magnetic field, the lower the voltage. The Hall sensor 6 converts the sensed magnetic field strength into a Hall voltage signal and transmits it to the single-chip microcomputer of the main control PCB board of the game steering wheel for analysis. The single-chip microcomputer judges actions such as the rotation direction, rotation angle, and number of rotation circles of the steering wheel based on this.

[0036] Embodiment 3: As Figures 6 to 11As shown in the figure, a Hall potential module for a game steering wheel includes a housing 1, a PCB board 2, and a rotating shaft 3. The housing 1 includes a box body 101 and a box cover 102. The PCB board 2 is installed in the box body 101. A rotating shaft mounting hole 103 is provided on the box cover 102. The rotating shaft 3 is rotatably installed in the rotating shaft mounting hole 103. The rotating shaft mounting hole 103 is provided with an internal thread 104, and the rotating shaft 3 is provided with an external thread 302. The rotating shaft 3 is in threaded cooperation with the rotating shaft mounting hole 103. A return spring 8 is provided between the rotating shaft 3 and the box cover 102. The rotating shaft 3 is located on one side of the PCB board 2. One end of the rotating shaft 3 facing the PCB board 2 is provided with a turntable 301. An eccentric magnet 5 is provided on the turntable 301. The magnet 5 makes a circular motion driven by the turntable 301. Four Hall sensors 6 (which can also be 2, 8, 16, etc. in other embodiments) cooperating with the magnet 5 are provided on the PCB board 2 and are evenly distributed on the circumference of a virtual circle. The virtual circle is coaxially arranged with the rotating shaft 3. The PCB board 2 is provided with a plug-in pin 7 connected to the main control circuit board.

[0037] Working principle: During assembly, the utility model is integrally inserted into the socket on the main control circuit board of the steering wheel through the plug-in pin 7. The rotating shaft 3 is docked with the main shaft of the steering wheel. The main shaft of the steering wheel drives the rotating shaft 3 to rotate together with the turntable, thereby driving the magnet 5 to rotate. When the magnet 5 rotates in a circumferential motion, the circumferential distance between the magnet 5 and the Hall sensors 6 changes. Each Hall sensor 6 sequentially senses the change in the magnetic field strength, thereby generating different Hall voltages. The Hall voltage changes with the change in the magnetic field strength. The stronger the magnetic field, the higher the voltage; the weaker the magnetic field, the lower the voltage. At the same time, under the cooperation of the thread of the rotating shaft 3 and the threaded hole, the axial distance between the magnet 5 and the Hall sensors 6 also changes. Therefore, at any angle of any number of turns of the steering wheel rotation, the magnetic field strength sensed by the Hall sensors 6 is unique (since the rotating shaft 3 rises / falls / extends with the thread, when the steering wheel rotates to the same steering angle in the first and second turns, the axial distance between the magnet 5 and the Hall sensors 6 is different, so the magnetic field strength sensed by the Hall sensors 6 is also different). The magnetic field strength sensed by several Hall sensors 6 is converted into Hall voltage signals and transmitted to the single-chip microcomputer of the main control PCB board of the game steering wheel for analysis. The single-chip microcomputer judges actions such as the rotation direction, rotation angle, and rotation number of turns of the steering wheel based on this.

[0038] Embodiment 4: As Figures 12 to 17As shown in the figure, a Hall potential module for a game steering wheel includes a housing 1, a PCB board 2, and a rotating shaft 3. The housing 1 includes a box body 101 and a box cover 102. The PCB board 2 is installed in the box body 101. A rotating shaft mounting hole 103 is provided on the box cover 102. The rotating shaft 3 is rotatably installed in the rotating shaft mounting hole 103. The rotating shaft mounting hole 103 is provided with an internal thread 104, and the rotating shaft 3 is provided with an external thread 302. The rotating shaft 3 is in threaded fit with the rotating shaft mounting hole 103. A return spring 8 is provided between the rotating shaft 3 and the housing 1. The rotating shaft 3 is located on one side of the PCB board 2. One end of the rotating shaft 3 facing the PCB board 2 is provided with a turntable 301. Four (which can also be 2, 8, 16, etc. in other embodiments) magnets 5 with gradually changing sizes are provided on the turntable 301 and are evenly distributed on the circumference of a virtual circle. The virtual circle is coaxially arranged with the rotating shaft 3. The magnets 5 make a circular motion driven by the turntable 301. An eccentric Hall sensor 6 cooperating with the magnets 5 is provided on the PCB board 2. The PCB board 2 is provided with a plug-in pin 7 connected to the main control circuit board.

[0039] Working principle: During assembly, the utility model is integrally inserted into the insertion port on the main control circuit board of the steering wheel through the plug-in pin 7. The rotating shaft 3 is docked with the main shaft of the steering wheel. The main shaft of the steering wheel drives the rotating shaft 3 and the turntable to rotate together, thereby driving multiple magnets 5 of different sizes (with different magnetic field strengths) to rotate. When the magnets 5 rotate for circumferential movement, the multiple magnets 5 pass by the Hall sensor 6 in sequence. The Hall sensor 6 can sense the change in magnetic field strength, thereby generating different Hall voltages. The Hall voltage changes with the change in magnetic field strength. The stronger the magnetic field, the higher the voltage; the weaker the magnetic field, the lower the voltage. At the same time, under the cooperation of the thread of the rotating shaft 3 and the threaded hole, the axial distance between the magnet 5 and the Hall sensor 6 will also change. Therefore, at any angle of any number of turns when the steering wheel rotates, the magnetic field strength sensed by the Hall sensor 6 is unique (since the rotating shaft 3 moves up and down / extends and contracts along the thread, when the steering wheel rotates to the same steering angle in the first and second turns, the axial distance between the magnet 5 and the Hall sensor 6 is different, so the magnetic field strength sensed by the Hall sensor 6 is also different). The magnetic field strength sensed by several Hall sensors 6 is converted into Hall voltage signals and transmitted to the single-chip microcomputer of the main control PCB board of the game steering wheel for analysis. The single-chip microcomputer determines actions such as the rotation direction, rotation angle, and number of turns of the steering wheel based on this.

Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied to other related technical fields, shall be similarly included in the patent protection scope of the present utility model.
