Description

Technical Field

[0001] This invention relates to potential modules, and more particularly to a Hall effect potential module for a game steering wheel. Background Technology

[0002] Existing Hall effect sensors for steering wheels require a magnet to be mounted on the steering wheel shaft, and a Hall sensor that works in conjunction with the magnet to be mounted on the main control circuit board. This assembly process is complex and has a high defect rate. For example, Chinese Patent Publication No. CN212785052 U, entitled "A Simulation Racing Game Console Host and Simulation Racing Game Console," discloses that "the magnetic ring is fixed on the rotating shaft," and that the sensor board and the Hall sensor on the sensor board move relative to the magnetic ring. The sensor board can only be fixed to the main control board of the game console, preventing integrated installation and making it prone to misalignment. Therefore, developing a Hall effect module for game steering wheels that improves the accuracy of magnet movement has become a pressing problem for those skilled in the art. Summary of the Invention

[0003] The present invention addresses the above-mentioned shortcomings by providing a Hall effect potential module for a game steering wheel.

[0004] The above-mentioned objective of the present invention is achieved through the following technical solution: A Hall effect potential module for a game steering wheel includes a housing, a PCB board, and a rotating shaft. The PCB board is installed in the housing, and the housing has a rotating shaft mounting hole. The rotating shaft is rotatably installed in the rotating shaft mounting hole. The rotating shaft is located on one side of the PCB board, and a turntable is provided at one end of the rotating shaft facing the PCB board. A magnet is eccentrically arranged on the turntable. The magnet moves in a circular motion under the drive of the turntable. The PCB board has a plurality of Hall effect sensors that cooperate with the magnet and are evenly distributed on the circumference of a virtual circle. The virtual circle is coaxial with the rotating shaft. The PCB board has a connector pin for connecting to the main control circuit board.

[0005] Furthermore, there are at least two Hall sensors.

[0006] The above-mentioned objective of the present invention is achieved through another technical solution: a Hall effect potential module for a game steering wheel, comprising a housing, a PCB board, and a rotating shaft. The PCB board is installed in the housing, and the housing is provided with a rotating shaft mounting hole. The rotating shaft is rotatably installed in the rotating shaft mounting hole. The rotating shaft is located on one side of the PCB board, and a turntable is provided at one end of the rotating shaft facing the PCB board. The turntable is provided with a plurality of magnets of progressively different sizes, which are evenly distributed on the circumference of a virtual circle. The virtual circle is coaxial with the rotating shaft. A Hall effect sensor that cooperates with the magnet is eccentrically arranged on the PCB board. The PCB board is provided with a connector pin for connection to the main control circuit board.

[0007] Furthermore, there are at least two magnets.

[0008] Furthermore, a bearing is fitted between the rotating shaft and the shaft mounting hole.

[0009] Furthermore, the rotating shaft mounting hole is provided with an internal thread, and the rotating shaft is provided with an external thread, with the rotating shaft and the rotating shaft mounting hole being threadedly engaged.

[0010] Furthermore, a return spring is provided between the rotating shaft and the outer casing.

[0011] Furthermore, the outer casing includes a box body and a box lid.

[0012] The advantages of this invention compared with the prior art are: the potential module of this invention adopts a modular design. When assembled into a game steering wheel, the entire invention can be connected to the main control circuit board of the steering wheel, which is simple and quick to assemble and effectively reduces the product defect rate.

[0013] Furthermore, the rotating shaft of this invention extends and retracts synchronously with the rotation, ensuring that the magnetic field strength sensed by the Hall sensor is unique at any angle and number of revolutions when the steering wheel is rotated. This allows for the determination of not only the direction of steering wheel rotation but also its rotation angle and number of revolutions. Moreover, the number of revolutions of the rotating shaft can exceed 360 degrees and can be set according to actual needs. Attached Figure Description

[0031] The invention will now be described in further detail with reference to the accompanying drawings.

[0032] Example 1: As Figure 1 , Figure 2 and Figure 5 As shown, a Hall effect 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 cover 102. The PCB board 2 is installed in the box body 101. The cover 102 has a rotating shaft mounting hole 103. The rotating shaft 3 is rotatably installed in the rotating shaft mounting hole 103. A bearing 4 is fitted 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. A turntable 301 is provided at one end of the rotating shaft 3 facing the PCB board 2. A magnet 5 is eccentrically arranged on the turntable 301. The magnet 5 makes a circular motion under the drive of the turntable 301. The PCB board 2 has 4 (in other embodiments, it can also be 2, 8, or 16, etc.) Hall sensors 6 that cooperate with the magnet 5 and are evenly distributed on the circumference of a virtual circle. The virtual circle is coaxial with the rotating shaft 3. The PCB board 2 has a connector 7 for connecting to the main control circuit board.

[0033] Working Principle: During assembly, this invention is fully inserted into the interface on the steering wheel's main control circuit board via the connector pin 7. The rotating shaft 3 is connected to the steering wheel spindle (a return spring may be provided depending on the situation). The steering wheel spindle drives the rotating shaft 3 and the turntable to rotate together, which in turn drives the magnet 5 to rotate. When the magnet 5 rotates in a circumferential motion, it passes through four Hall sensors 6 in sequence. Each Hall sensor 6 senses the change in magnetic field strength in turn, thereby generating different Hall voltages. The Hall voltage changes with the magnetic field strength; the stronger the magnetic field, the higher the voltage, and the weaker the magnetic field, the lower the voltage. The four Hall sensors 6 convert the sensed magnetic field strength into Hall voltage signals, which are then transmitted to the microcontroller on the main control PCB board of the game steering wheel for analysis. This allows the system to determine the steering wheel's rotation direction, rotation angle, and number of rotations.

[0034] Example 2: As Figure 3 , Figure 4 and Figure 5 As shown, a Hall effect 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 cover 102. The PCB board 2 is installed in the box body 101. The cover 102 has a rotating shaft mounting hole 103. The rotating shaft 3 is rotatably installed in the rotating shaft mounting hole 103. A bearing 4 is fitted 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. A turntable 301 is provided at one end of the rotating shaft 3 facing the PCB board 2. The turntable 301 has 4 magnets 5 of gradually varying sizes (in other embodiments, it can also be 2, 8, or 16, etc.) and is evenly distributed on the circumference of a virtual circle. The virtual circle is coaxial with the rotating shaft 3. The magnets 5 move in a circle under the drive of the turntable 301. A Hall sensor 6 that cooperates with the magnets 5 is eccentrically arranged on the PCB board 2. The PCB board 2 has a connector pin 7 for connecting to the main control circuit board.

[0035] Working Principle: During assembly, this invention is fully inserted into the connector on the steering wheel's main control circuit board via the connector pin 7. The rotating shaft 3 is connected to the steering wheel spindle (a return spring may be provided depending on the situation). The steering wheel spindle drives the rotating shaft 3 and the turntable to rotate together, which in turn drives the four magnets 5 to rotate. When the four magnets 5 rotate in a circumferential motion, each magnet 5 passes through the Hall sensor 6 in sequence. The Hall sensor 6 senses the changes in magnetic field strength in sequence, thereby generating different Hall voltages. The Hall voltage changes with the magnetic field strength; the stronger the magnetic field, the higher the voltage, and the weaker the magnetic field, the lower the voltage. The Hall sensor 6 converts the sensed magnetic field strength into a Hall voltage signal, which is transmitted to the microcontroller on the main control PCB board of the game steering wheel for analysis. The microcontroller uses this signal to determine the steering wheel's rotation direction, rotation angle, and number of rotations.

[0036] Example 3: As Figures 6 to 11 As shown, a Hall effect 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 cover 102. The PCB board 2 is installed in the box body 101. The cover 102 has a rotating shaft mounting hole 103. The rotating shaft 3 is rotatably mounted in the rotating shaft mounting hole 103. The rotating shaft mounting hole 103 has an internal thread 104, and the rotating shaft 3 has an external thread 302. The rotating shaft 3 is threadedly engaged with the rotating shaft mounting hole 103. A return spring is provided between the rotating shaft 3 and the cover 102. Spring 8; The rotating shaft 3 is located on one side of the PCB board 2. A turntable 301 is provided at one end of the rotating shaft 3 facing the PCB board 2. A magnet 5 is eccentrically arranged on the turntable 301. The magnet 5 moves in a circle under the drive of the turntable 301. The PCB board 2 is provided with 4 (in other embodiments, it can also be 2, 8 or 16, etc.) Hall sensors 6 that cooperate with the magnet 5 and are evenly distributed on the circumference of a virtual circle. The virtual circle is coaxial with the rotating shaft 3. The PCB board 2 is provided with a connector 7 for connecting to the main control circuit board.

[0037] Working principle: During assembly, the present invention is inserted into the interface on the steering wheel main control circuit board through the plug pin 7. The rotating shaft 3 is connected to the steering wheel main shaft. The steering wheel main shaft drives the rotating shaft 3 and the turntable to rotate together, which in turn drives the magnet 5 to rotate. When the magnet 5 rotates and moves in a circumferential direction, the distance between the magnet 5 and the Hall sensor 6 changes in the circumferential direction. Each Hall sensor 6 senses the change in magnetic field strength in turn, 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, and the weaker the magnetic field, the lower the voltage. Meanwhile, with the engagement of the thread and threaded hole of the rotating shaft 3, the axial distance between the magnet 5 and the Hall sensor 6 will also change. Therefore, when the steering wheel is rotated to any angle of any number of revolutions, the magnetic field strength sensed by the Hall sensor 6 is unique (because the rotating shaft 3 rises / falls / extends with the thread, when the steering wheel is rotated to the same steering angle of the first and second revolutions, 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 sensed magnetic field strength is converted into Hall voltage signals by several Hall sensors 6 and transmitted to the microcontroller of the main control PCB board of the game steering wheel for analysis. The microcontroller determines the steering wheel rotation direction, rotation angle, and number of revolutions based on this signal.

[0038] Example 4: Figures 12 to 17As shown, a Hall effect 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 cover 102. The PCB board 2 is installed in the box body 101. The cover 102 has a rotating shaft mounting hole 103. The rotating shaft 3 is rotatably mounted in the rotating shaft mounting hole 103. The rotating shaft mounting hole 103 has an internal thread 104, and the rotating shaft 3 has an external thread 302. The rotating shaft 3 is threadedly engaged 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. A turntable 301 is provided at one end of the rotating shaft 3 facing the PCB board 2. The turntable 301 is provided with 4 magnets 5 of gradually varying sizes (in other embodiments, it can also be 2, 8 or 16, etc.) and is evenly distributed on the circumference of a virtual circle. The virtual circle is coaxial with the rotating shaft 3. The magnets 5 move in a circle under the drive of the turntable 301. A Hall sensor 6 that cooperates with the magnets 5 is eccentrically provided on the PCB board 2. The PCB board 2 is provided with a connector pin 7 that connects to the main control circuit board.

[0039] Working principle: During assembly, the present invention is inserted into the interface on the steering wheel main control circuit board through the plug pin 7. The rotating shaft 3 is connected to the steering wheel main shaft. The steering wheel main shaft drives the rotating shaft 3 and the turntable to rotate together, which in turn drives multiple magnets 5 of different sizes (with different magnetic field strengths) to rotate. When the magnets 5 rotate and move in a circumferential direction, the multiple magnets 5 pass through 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, and the weaker the magnetic field, the lower the voltage. Meanwhile, with the engagement of the thread and threaded hole of the rotating shaft 3, the axial distance between the magnet 5 and the Hall sensor 6 will also change. Therefore, when the steering wheel is rotated to any angle of any number of revolutions, the magnetic field strength sensed by the Hall sensor 6 is unique (because the rotating shaft 3 rises / falls / extends with the thread, when the steering wheel is rotated to the same steering angle of the first and second revolutions, 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 sensed magnetic field strength is converted into Hall voltage signals by several Hall sensors 6 and transmitted to the microcontroller of the main control PCB board of the game steering wheel for analysis. The microcontroller determines the steering wheel rotation direction, rotation angle, and number of revolutions based on this signal.
