Description

Technical Field

[0001] The utility model relates to a potential module, in particular to an axially telescopic Hall potential module. Background Art

[0002] In the existing game controller field, for the buttons applying Hall potential devices, generally, a pressing mechanical structure is used to change the distance between a magnet and a Hall sensor, so that the Hall sensor generates different magnitudes of magnetic fluxes, and the Hall sensor converts the magnetic fluxes into corresponding strong and weak electrical signals for output. However, the uneven force during manual control of this pressing structure results in poor control accuracy in game scenarios and affects the game experience. Currently, on the market, there are also some structures that use a rotating shaft to move the magnet in a circle, thereby changing the distance between the magnet and the Hall sensor. For example, the structure disclosed in the utility model patent with the Chinese patent publication number CN 209495710 U and the name "Hall potentiometer". Although this structure changes the pressing method, since its rotating shaft is an idling structure (generally equipped with bearings), mainly relying on the control of hand force and without any auxiliary structure, the accuracy of the rotating shaft during rotation still cannot be controlled, which is inconvenient for game operation in specific game scenarios. Moreover, its rotating shaft cannot be lifted or lowered, and the magnet can only move within a range of 360 degrees in the same plane at most. When the potentiometer is applied to a game steering wheel or other devices or functional rotations that require more than 360 degrees of rotation, it cannot be applied. Therefore, researching and developing an axially telescopic Hall potential module to improve the accuracy of magnet movement has become an urgent problem for those skilled in the art. Summary of the Utility Model

[0003] The utility model is to solve the above deficiencies and provides an axially telescopic Hall potential module.

[0004] The above object of the utility model is achieved by the following technical solutions: An axially telescopic Hall potential module, characterized in that: it includes a PCB board and a telescopic shaft. The telescopic shaft is located on one side of the PCB board, and a magnet is provided at one end of the telescopic shaft facing the PCB board. A Hall sensor axially arranged with the magnet and the telescopic shaft is provided on the PCB board.

[0005] Further, the magnet is arranged on the end face or the side wall of the end of the telescopic shaft.

[0006] Further, the axially telescopic Hall potential module includes a housing, and a threaded shaft hole is provided on the housing. An external thread is provided on the telescopic shaft and is installed in the threaded shaft hole. Thus, the telescopic shaft realizes stable telescoping through its own thread.

[0007] Further, a return torsion spring is provided between the telescopic shaft and the housing. One end of the return torsion spring is fixed to the telescopic shaft, and the other end is fixed to the housing.

[0008] Further, the axially telescopic Hall potential module includes a housing with an axial guide hole. The telescopic shaft passes through the axial guide hole. The inner wall of the axial guide hole is provided with guide keys, and the outer wall of the telescopic shaft is provided with guide grooves that cooperate with the guide keys. One end of the outer part of the telescopic shaft is provided with an external driving rotating shaft, and a threaded driving structure is arranged between the rear end of the telescopic shaft and the external driving rotating shaft. Thus, the telescopic shaft is telescoped by means of the external driving rotating shaft.

[0010] The advantages of the present utility model compared with the prior art are as follows: The present utility model realizes the telescoping of the telescopic shaft by rotating, thereby changing the distance between the magnet and the Hall sensor. This is more stable and has higher control accuracy compared with the pressing type driving structure. Moreover, compared with the structure in which the magnet approaches or moves away from the Hall sensor laterally in the circumferential direction, the change in magnetic flux is also more uniform and stable. At the same time, the rotation angle of the rotating shaft can far exceed 360 degrees, which is convenient for application in game steering wheels or other game devices or equipment that require rotation of more than one circle.

[0025] Embodiment 1: As Figures 1 to 4 shown, an axially telescopic Hall potential module includes a housing 1, a PCB board 2, and a telescopic 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 threaded shaft hole 103 is provided on the box cover 102. An external thread 301 is provided on the telescopic shaft 3 and is installed in the threaded shaft hole 103. A return torsion spring 4 is provided between the telescopic shaft 3 and the housing 1. One end of the return torsion spring 4 is fixed to the telescopic shaft 3, and the other end is fixed to the housing 1.

A magnet 5 is provided at one end of the telescopic shaft 3 facing the PCB board 2. A Hall sensor 6 axially aligned with the magnet 5 and the telescopic shaft 3 is provided on the PCB board 2.

[0026] During operation, by rotating the telescopic shaft to perform telescopic movement, the distance between the magnet and the Hall sensor is changed. The Hall voltage changes with the change of the magnetic field strength. The closer the magnet is to the Hall sensor, the stronger the magnetic field and the higher the voltage. Conversely, the weaker the magnetic field, the lower the voltage. The Hall sensor transmits the voltage signal to the single-chip microcomputer on the PCB board, and the single-chip microcomputer then outputs a corresponding command signal based on this.

[0027] Embodiment 2: As Figures 5 to 8As shown in the figure, an axially telescopic Hall potential module includes a housing 1, a PCB board 2, and a telescopic 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. The box cover 102 is provided with a shaft guiding hole 7. The telescopic shaft 3 passes through the shaft guiding hole 7. The hole wall of the shaft guiding hole 7 is provided with a guiding key 701. The outer wall of the telescopic shaft 3 is provided with a guiding groove 302 that cooperates with the guiding key 701. One end of the outer part of the telescopic shaft 3 is provided with an external driving rotating shaft 8. A threaded driving structure 9 is provided between the rear end of the telescopic shaft 3 and the external driving rotating shaft 8. The threaded driving structure 9 adopts a screw-threaded hole fit (as Figures 5 to 8 shown), that is, a threaded hole 901 is provided at the rear end of the telescopic shaft 3 to cooperate with the screw 902 of the external driving rotating shaft 8. A return spring (not shown in the figure) is provided between the external driving rotating shaft 8 and the housing 1 or an external device housing (not shown in the figure). Thus, the telescopic shaft 3 realizes stable telescoping through the external driving rotating shaft 8. The telescopic shaft 3 is located on one side of the PCB board 2. One end of the telescopic shaft 3 facing the PCB board 2 is provided with a magnet 5. The PCB board 2 is provided with a Hall sensor 6 arranged coaxially with the magnet 5 and the telescopic shaft 3.

[0028] Embodiment 3: As Figures 9 to 12 shown, an axially telescopic Hall potential module includes a housing 1, a PCB board 2, and a telescopic 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. The box cover 102 is provided with a shaft guiding hole 7. The telescopic shaft 3 passes through the shaft guiding hole 7. The hole wall of the shaft guiding hole 7 is provided with a guiding key 701. The outer wall of the telescopic shaft 3 is provided with a guiding groove 302 that cooperates with the guiding key 701. One end of the outer part of the telescopic shaft 3 is provided with an external driving rotating shaft 8. A threaded driving structure 9 is provided between the rear end of the telescopic shaft 3 and the external driving rotating shaft 8. The threaded driving structure 9 adopts a spiral pushing protrusion fit, that is, a first threaded slope surface 903 is provided on the telescopic shaft 3, and a second threaded slope surface 904 that cooperates with the first threaded slope surface is provided on the external driving rotating shaft 8. A return spring (not shown in the figure) is provided between the external driving rotating shaft 8 and the housing 1 or an external device housing (not shown in the figure). Thus, the telescopic shaft 3 realizes stable telescoping through the external driving rotating shaft 8. The telescopic shaft 3 is located on one side of the PCB board 2. One end of the telescopic shaft 3 facing the PCB board 2 is provided with a magnet 5. The PCB board 2 is provided with a Hall sensor 6 arranged coaxially with the magnet 5 and the telescopic shaft 3.

[0029] In the operation of Embodiment 2 and Embodiment 3 of the present utility model, by rotating the external drive shaft, the telescopic shaft is driven to perform telescopic movement, changing the distance between the magnet and the Hall sensor. The Hall voltage changes with the change of the magnetic field strength. The closer the magnet is to the Hall sensor, the stronger the magnetic field and the higher the voltage. Conversely, the weaker the magnetic field, the lower the voltage. The Hall sensor transmits this voltage signal to the single-chip microcomputer on the PCB board, and the single-chip microcomputer then outputs corresponding command signals accordingly.

[0030] In fact, Embodiment 1, Embodiment 2, and Embodiment 3 all adopt a threaded drive structure, enabling the telescopic shaft to smoothly telescope under the guiding action of the threaded structure. The threaded structure not only has a guiding effect but also a scale-like effect, and its control accuracy is easier to control.

[0031] Embodiment 4: Except that the magnet 5 is arranged on the end side wall of the telescopic shaft 3 (as Figure 13 shown), the rest of the structure is the same as that of Embodiment 1 or Embodiment 2 or Embodiment 3.

[0032] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. 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 in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
