Description

Technical Field

[0001] This disclosure relates to the technical field of handles for control, and more specifically, to a handle for control, a method for compensating the handle trigger, and an electronic device. Background Technology

[0002] Handsets used for control can be applied in many fields. Such handsets typically include at least one of a joystick, buttons, and triggers. For example, they can be used in virtual reality technology and networking technology. In virtual reality or interactive gaming products, users can use handsets to control objects within these products.

[0003] For example, the controllers in virtual reality devices typically use a combination of magnets and magnetic sensors to detect trigger action. The movement of the trigger moves the magnet, causing a change in the magnetic field strength detected by the magnetic sensor on the circuit board. This, in turn, changes the output voltage of the magnetic sensor. The microcontroller unit (MCU) determines the trigger action by detecting this change in output voltage.

[0004] However, in actual use, the magnetic field strength of the magnets weakens over time. Furthermore, environmental factors such as high temperature and high humidity also reduce the magnetism. This causes the output voltage detected by the microcontroller to exceed the preset voltage range. Especially when the trigger is fully released or fully pressed, the reduced magnetism may cause the microcontroller to misinterpret the trigger release and press actions. This can significantly impact the user experience. Summary of the Invention

[0005] One object of this disclosure is to provide a new technical solution for a handle.

[0006] According to a first aspect of this disclosure, a control handle is provided, comprising: a trigger unit; and a control unit, wherein the trigger unit includes a trigger, a magnet, a magnetic sensing device, and a support, one of the magnet and the magnetic sensing device being located on the trigger and the other on the support, wherein when the trigger moves relative to the support, the magnetic sensing device outputs a sensing signal representing the movement of the trigger, wherein the trigger unit further includes an adjustment coil wound around the magnet; and wherein the control unit outputs a first control signal to control the adjustment coil, thereby adjusting the magnetic field generated by the magnet.

[0007] According to a second aspect of this disclosure, a method for compensating a handle trigger according to an embodiment is provided, comprising: acquiring a first sensing signal about the trigger; determining that the sensing signal does not satisfy preset parameters; outputting a first control signal to control the adjustment coil, thereby adjusting the magnetic field generated by the magnet; generating a second sensing signal using the sensed magnetic field; determining that the second sensing signal satisfies preset parameters; and setting a current for adjusting the magnetic field generated by the magnet for compensating the handle trigger in use.

[0008] According to a third aspect of this disclosure, an electronic device is provided, comprising: a handle as described in an embodiment.

[0009] According to embodiments of this disclosure, the performance of the handle can be effectively improved by compensating for the weakened magnetic field strength of the magnet and / or by compensating for the output voltage of the magnetic induction device.

[0010] Other features and advantages of this disclosure will become clear from the following detailed description of exemplary embodiments with reference to the accompanying drawings. Attached Figure Description

[0017] Figure 6 A schematic diagram of an electronic device according to one embodiment is shown. Detailed Implementation

[0018] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present disclosure.

[0019] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use.

[0020] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0021] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0022] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0023] Figure 1 A schematic diagram of a trigger is shown. (For example...) Figure 1 As shown, the trigger unit includes: a trigger rotation shaft 1, a trigger shaft spring 2, a trigger (trigger plastic part) 4, a magnet 3, a magnetic induction device 5 located on a circuit board 6, and a circuit board 6. Figure 1 Position A, indicated by the solid line, is the position when the trigger is released. Figure 1 The position B shown by the dashed line is the position when the trigger is pressed.

[0024] Figure 2 A schematic diagram of a trigger according to one embodiment is shown. Figure 1 As shown, the trigger unit includes a trigger 14, a magnet 13, a magnetic induction device 15, and a support 16. The support 16 is, for example, the circuit board of the trigger.

[0025] exist Figure 2 In this configuration, magnet 13 is positioned on trigger 14, and magnetic sensing device 15 is located on support 16. When trigger 14 moves relative to support 16, magnetic sensing device 15 outputs a sensing signal indicating the movement of trigger 14.

[0026] Here, "signal" can be voltage, current, etc.

[0027] exist Figure 2 The trigger unit also includes an adjustment coil 16. The adjustment coil 16 is wound around a magnet 13. A control unit on the circuit board can output a first control signal to control the adjustment coil 16, thereby adjusting the magnetic field generated by the magnet 13. For example, in... Figure 2 In the circuit, the adjusting coil 16 is connected to the voltage compensation unit 18 on the circuit board via the wire 17 to receive the first control signal.

[0028] In one embodiment, the magnetic field of the magnet can be adjusted by incorporating a coil on the magnet. This allows the trigger to function normally even if the magnet's magnetism is inconsistent or demagnetized. On one hand, this can be used when the magnet becomes demagnetized. On the other hand, even if the magnet's magnetism is inconsistent during the manufacturing process, it can still ensure good trigger performance.

[0029] In one embodiment, the magnet 13 is located on the support 6, and the magnetic induction device 15 is located on the trigger 14. In this case, the setting coil 16 is also relatively fixed. In this embodiment, interference from magnetic field changes and / or power consumption caused by movement of the setting coil 16 can be reduced. Compared to placing the magnetic induction device 15 on the support 6, interference caused by guiding movement can be reduced overall.

[0030] For example, magnet 13 can be any type of magnet, such as a ferrite magnet. In one embodiment, magnet 13 can be a softer magnet with a coercivity of less than 20 Oersted. Here, "softer magnet" refers to the coercivity of the magnet, not the softness or hardness of the magnet itself. On the one hand, a softer magnet can reduce the impact on surrounding parts and equipment when the handle stops working. On the other hand, a softer magnet can be magnetized to some extent when a magnetic field generated by the coil is applied, thereby strengthening its magnetic field.

[0031] Figure 3 A block diagram of a handle according to one embodiment is shown schematically.

[0032] exist Figure 3 In the process, the sensing signal output by the magnetic induction device 15 is sent to the signal switching unit 24.

[0033] The control unit 30 can control the signal switching unit 24 via a control signal through the line shown by the dashed line. When no compensation is required, the signal switching unit 24 can directly send the sensing signal to the control unit 30. When compensation is required, the signal switching unit 24 sends the sensing signal to the detection unit 25.

[0034] The detection unit 25 detects the sensing signal.

[0035] The control unit 30 can also control the additional signal switching unit 26 via a control signal through the line shown by the dashed line. When no compensation is required, the additional signal switching unit 26 can directly send the sensing signal to the control unit 30. When compensation is required, the additional signal switching unit 26 sends the sensing signal to the adjustment signal generation unit 27.

[0036] The adjustment signal generation unit 27 generates an adjustment signal based on the sensing signal. The compensation unit 28 compensates the sensing signal based on the adjustment signal and outputs the compensated sensing signal to the control unit 30. For example, the compensation unit 28 superimposes the adjustment signal onto the sensing signal to achieve compensation of the sensing signal.

[0037] When the sensing signal is in an abnormal state, the control unit 30 outputs a first control signal to control the adjustment coil, thereby adjusting the magnetic field generated by the magnet. For example, the abnormal sensing voltage may include the following abnormal situation: if the sensing signal is detected to be outside a preset range N times consecutively, the sensing signal does not meet the preset parameters. For example, N is greater than or equal to 3. The preset parameters are, for example, preset standard signal values ​​or ranges when the trigger is released or pressed to the maximum position.

[0038] For example, Figure 1 The handle shown also includes a current generating circuit 22. The current generating circuit 22 receives a first control signal from the control unit 30 and generates a first current for adjusting the magnetic field. This first current is input to the adjustment coil 16. The magnitude of the current generated by the current generating circuit 22 can be adjusted according to the first control signal. Thus, the desired magnetic field can be generated in the adjustment coil 16 as needed.

[0039] In this embodiment, the magnetic field of the magnet can be enhanced by adding a coil around the magnet 13. Furthermore, adding a compensation unit at the output of the magnetic induction device can effectively compensate for any deviations in the output of the magnetic induction device.

[0040] When current flows through the coil wound around magnet 13, a magnetic field is generated, which can compensate for the magnetism lost due to demagnetization of magnet 13. Compensation unit 28 compensates for the output of magnetic induction device 15, so that the voltage signal received by control unit 30 is within a preset range.

[0041] The adjustment signal generation unit 27 can generate an adjustment signal of a fixed magnitude. The compensation unit 28 can store this adjustment signal. For example, the adjustment signal can be the difference between the sensing signal when the trigger is released or pressed to its maximum position and a preset standard signal. During use of the handle, the compensation unit 28 superimposes this adjustment signal onto the sensing signal. For example, the compensation unit 28 can directly superimpose the adjustment signal onto the sensing signal, or it can superimpose the adjustment signal onto the sensing signal proportionally. The proportion is, for example, the ratio of the current sensing signal to the sensing signal when the trigger is pressed to its maximum position.

[0042] Figure 4 A flowchart illustrating a method for compensating a handle trigger according to one embodiment is shown schematically.

[0043] In step S1, a first sensing signal about the trigger is acquired.

[0044] In step S2, it is determined that the sensing signal does not meet the preset parameters. If the sensing signal is detected to be outside the preset range N times consecutively, it is determined that the sensing signal does not meet the preset parameters.

[0045] In step S3, a first control signal is output to control the adjustment coil, thereby adjusting the magnetic field generated by the magnet.

[0046] For example, after receiving an external command or detecting an abnormality in the sensing signal, a first control signal is output.

[0047] In step S4, a second sensing signal is generated using the sensed magnetic field.

[0048] In step S5, it is determined that the second sensing signal meets the preset parameters.

[0049] In step S6, a current is set to adjust the magnetic field generated by the magnet in order to compensate the handle trigger during use.

[0050] For example, an adjustment signal can be generated based on the second sensing signal. The second sensing signal is then compensated based on the adjustment signal. It is determined that the second sensing signal meets preset parameters. The adjustment signal is then set to compensate the handle trigger during use.

[0051] Figure 5 A flowchart illustrating compensation for a handle trigger according to one embodiment is shown schematically.

[0052] like Figure 5 As shown, in s31, the magnetic sensing device 15 senses the change in the magnetic field and outputs a sensing signal.

[0053] When the user presses the trigger, the magnetic sensor outputs a corresponding voltage value based on the degree of pressure applied.

[0054] In step s32, it checks whether the usage time of the controller exceeds a preset time. If it does not exceed the preset time, it proceeds to step s42, outputting a sensing signal without compensation. If it exceeds the preset time, it proceeds to step s33.

[0055] Before the handle's lifespan reaches the preset duration, the demagnetization of the magnet has minimal impact on the control unit's detection. In this case, no compensation is required. The signal switching unit 24 directly sends the sensing signal to the control unit 30. This corresponds to... Figure 3 Pathway A in the middle.

[0056] In s33, the detection unit 25 detects the sensing signal.

[0057] In step s34, if the sensing signal is within a preset range, proceed to step s42, where the sensing signal is displayed without compensation. If the sensing signal exceeds the preset range, proceed to step s35.

[0058] When the handle's lifespan reaches a preset duration, the signal switching unit 24 outputs a signal to the detection unit 25 instead of directly to the control unit 30. The detection unit 25 checks whether the sensing signal is within a preset range. When the sensing signal exceeds the preset range, the control unit 30 controls the current generating circuit 22 to generate current, thereby generating a magnetic field with the same polarity as the magnet within the coil 16, compensating for the magnet's magnetic field strength. This allows adjustment of the output signal of the magnetic induction device 15. The current generating circuit 22 can be adjusted multiple times under the control of the control unit 30, thereby repeatedly adjusting the coil's magnetic field strength until the demagnetization of the magnet is compensated. This corresponds to... Figure 3 Pathway 2 in the middle.

[0059] In s35, the control unit 30 generates a first control signal to control the current generating circuit 22 to generate a control current.

[0060] In step s36, a control current is applied to the adjusting coil 16. This causes the magnetic field generated by the adjusting coil 16 to superimpose with the magnetic field generated by the magnet 13, thereby producing an enhanced magnetic field.

[0061] In s37, the magnetic sensing device 15 senses the change in the magnetic field and outputs a sensing signal.

[0062] In step s38, if the sensing signal is within the preset range, proceed to step s42 and output the sensing signal. If the sensing signal exceeds the preset range, proceed to steps s35 and s39. In this case, the magnetic field can be readjusted and the sensing signal can be compensated.

[0063] In s39, the adjustment signal generation unit 26 generates an adjustment signal based on the sensing signal.

[0064] In s40, the compensation unit 27 compensates the sensing signal based on the adjustment signal and outputs the compensated sensing signal to the control unit 30.

[0065] In step s41, if the sensing signal is within the preset range, proceed to step s42 and output the sensing signal. If the sensing signal exceeds the preset range, proceed to step 39 and recompensate the sensing signal.

[0066] In s42, the sensing signal is output to the control unit 30.

[0067] After adjusting the magnetic field of coil 13, if the output of magnetic induction device 15 still does not meet the preset range, control unit 30 controls additional signal switching unit 26 to switch to adjustment signal generation unit 27. Adjustment signal generation unit 27 compares the detection result of detection circuit 25 with the preset voltage range and generates an adjustment signal.

[0068] The compensation unit 28 superimposes the adjustment signal onto the sensing signal, thereby adjusting the sensing signal to a normal voltage range that the control unit 30 can determine, and then outputs the adjusted sensing signal to the control unit 30. This corresponds to... Figure 3 Pathway C in the middle.

[0069] For example, the trigger compensation function disclosed in the embodiments can be built into the trigger device as a feature option, or it can be set in the application used to control the trigger. For example, the control unit inside the handle can initiate the calibration operation of the magnet by means of a command (e.g., pressing and holding a specific button for 3 seconds). In this case, the user can release the trigger or press it fully to the maximum stop position according to the instruction. The control unit can automatically perform the compensation calibration.

[0072] like Figure 6 As shown, the electronic device in the embodiment may include a combination system of a handle. As an example, in Figure 6 In this device, the electronic component includes a handle 71 and a display device 72. The handle 71 includes a trigger 73. Figure 6 In this embodiment, display device 71 is shown as a display; however, in other embodiments, display 71 may also be virtual reality glasses, augmented reality glasses, projection devices, etc.
