Background Art

[0002] With the improvement of living standards, the frequency of using a joystick in games is increasing. However, the identification of joystick operations is a relatively important technical content in game handles. The thin-film resistance joystick is a relatively widely used type among them. In related technologies, a general thin-film resistance joystick is limited by the influence of the process, has a short service life, and the thin-film resistance joystick is prone to carbon particle adsorption problems due to the friction between the leaf spring and the thin-film resistance during use, which easily causes drift problems and deteriorates the performance stability. To solve the above problems, hall joysticks have appeared in the market, but the power consumption of hall joysticks is relatively high and they are not applicable to low-power consumption products.

[0003] To solve the defects that the thin-film resistance joystick has a short lifespan and poor stability, and the hall joystick has relatively high power consumption, a conventional capacitive joystick device, for example, the patent with the publication number CN105224103A, discloses a capacitive joystick device, detects the operation of the operating lever by a capacitive sensor, and further obtains a detection signal. However, the accuracy of this capacitive detection structure is very low, and at the same time, due to the limitation of the structural space of the joystick, it is difficult to implement this structure. Also, even when two electrodes are set directly opposite to perform capacitive detection, it is difficult to identify minute position changes between the two electrodes due to the influence of the two electrode pitches, resulting in a low operation detection sensitivity of the joystick. At the same time, it is also limited by the structural space of the joystick, and it is difficult to provide sufficient movement space for the electrodes, making it difficult to realize a joystick with such a structure.

[0004] The above defects are worth resolving. [Overview of the project] [Problems that the invention aims to solve]

Modes for Carrying Out the Invention

[0021] Hereinafter, the present invention will be further described in conjunction with the accompanying drawings and embodiments.

[0022] As shown in Figures 1 to 6, the present invention proposes a game handle including a handle body equipped with a capacitive joystick in order to overcome the short lifespan and drift of conventional thin-film resistive joysticks and the high power consumption of Hall joysticks. This capacitive joystick is a non-contact type capacitive joystick, which reduces the lifespan reduction and drift problems due to wear by connecting without contact, and improves the accuracy of joystick position detection by obtaining the joystick position change by the amount of change in the capacitance value.

[0023] The capacitive joystick includes a joystick component 10 and a capacitive sensor component 20, wherein the joystick component 10 is used to acquire human operation movements and output a mechanical operation signal based on said movements, and the capacitive sensor component 20 is used to output a capacitive signal based on the mechanical operation signal of the joystick component 10 and transmit it to a main circuit board for data analysis to obtain a joystick position signal.

[0024] 1. Joystick component The joystick component 10 has a control terminal and at least one output terminal, the output terminal being connected to the rotary shaft 111, where the control terminal is used for human control and the output terminal is used to output a mechanical operation signal.

[0025] Specifically, the joystick component 10 includes a housing, a joystick body 11 assembled to the housing, and a rotating part. The housing may be directly attached to the main circuit board as a support base for the entire joystick component 10, or it may be attached to another position on the game handle. Specifically, when the joystick component 10 is directly attached to the main circuit board, the housing of the joystick component 10 has mounting feet, and the housing is attached to the main circuit board via the mounting feet.

[0026] The joystick body 11 has at least two ends, one end of which is a control terminal for receiving human control movements, and the other end which protrudes into the housing and is connected to a rotating part, the rotating part being controlled by the other end of the joystick body 11 and used to output mechanical operation signals, and the rotating part has an output terminal for controlling the capacitive sensor component 20.

[0027] In a preferred embodiment, the joystick body 11 in the joystick component 10 is implemented in an almost omnidirectional rotation manner, so the rotating part in the present invention includes a first rotation axis and a second rotation axis, the second rotation axis being annularly mounted within the first rotation axis to form a joint, and the joystick body 11 is connected to the second rotation axis by passing through the first rotation axis.

[0028] To enable the joystick body 11 to rotate in all directions, a first oscillating rail is provided within the first rotation axis, and a second oscillating rail is provided within the second rotation axis, and the first and second oscillating rails intersect each other (preferably two perpendicularly intersecting planes). The first rotation axis has a first axis, which is hinged to the housing and is used for the first rotation axis, the second rotation axis and the joystick body 11 to oscillate in the first plane. The second rotation axis has a second axis, which passes through the first rotation axis and is hinged to the housing and is used for the second rotation axis and the joystick body 11 to oscillate in the second plane. The present invention achieves omnidirectional rotation of the joystick body 11 through the mutual fitting between the first rotation axis, the second rotation axis and the joystick body 11 and the housing.

[0029] Of course, in other embodiments, the joystick body 11 can further achieve omnidirectional rotation by a rotating part of a different structure, and the present invention is not limited thereto.

[0030] Furthermore, the present invention can also address the need for the joystick body 11 to rotate in a single plane, where the rotating part is selected to have only one joint structure, and the rotation output of the rotation axis 111 of the joystick body 11 can be realized by the joystick body 11 rotating within the swing rail of the joint. Of course, if the joystick body 11 is directly configured to form the rotation axis 111, the rotation axis 111 can serve as an output terminal for mechanical operation signals, i.e., the joystick body 11 has both a control terminal and an output terminal at the same time.

[0031] The joystick component 10 further includes a return member located within the housing to provide a restorative force for the joystick body 11. Specifically, a bottom plate is provided below the housing, and the housing is snap-fitted to the bottom plate (not shown). One end of the return member abuts against the bottom plate at the bottom of the housing, and the other end abuts against the joystick body 11. When the joystick body 11 receives a pressing force, the return member is pressed against it, and when the pressing force is lost, the return member returns the joystick body 11 to its original position. Preferably, the return member can be a spring.

[0032] 2. Capacitive sensor component The capacitive sensor component 20 in the present invention includes at least one, and the capacitive sensor component 20 is connected to the rotation axis 111 of the joystick component 10. If there are two or more capacitive sensor components 20, each capacitive sensor component 20 is connected to one rotation axis 111 of the joystick component 10.

[0033] Each capacitive sensor component 20 includes a rotating plate 24, metal pieces 23 spaced apart from each other and forming a capacitive field, and a PCB board 25. The metal pieces 23 and the PCB board 25 form a capacitive field spaced apart from each other, but the rotating plate 24 is connected to the rotation axis 111 and is positioned between the metal pieces 23 and the PCB board 25. In the normal state, the capacitive field between the metal pieces 23 and the PCB board 25 is separated by the rotating plate 24. However, as the rotating plate 24 rotates according to the rotation axis 111, the stacking area between the metal pieces 23 and the PCB board 25 changes, and a change in the capacitance value between them is realized. Furthermore, the rotation status of the rotating plate 24 can be obtained by detecting the capacitance value between the metal pieces 23 and the PCB board 25.

[0034] The rotating plate 24 includes a rotating shaft 241 connected to a rotating shaft 111 and a shutter 242, where the rotating shaft 241 is used to receive the drive of the rotating shaft 111 and rotate the shutter 242, and the shutter 242 is used to shield the metal piece 23 and the PCB board 25 to realize a change in the capacitive field between them. Preferably, the rotating shaft 241 has an axial hole 243, and the rotating shaft 241 is connected to the rotating shaft 111 via the axial hole 243, and by selecting a non-circular hole for the axial hole 243, the rotating shaft 241 can be rotated when the rotating shaft 111 rotates. Preferably, the rotating plate 24 in the present invention includes an insulating material, such as plastic or ceramic, so as not to affect the capacitive field between the metal piece 23 and the PCB board 25.

[0035] Furthermore, when the PCB board 25 is connected to the main circuit board, the PCB board 25 measures the capacitance value between itself and the metal piece 23, then transmits the capacitance data to the main circuit board, which calculates and outputs the data change according to the change in capacitance value (this data change includes voltage change and current change). Specifically, the main circuit board can obtain rotation information of the rotating plate 24, i.e., rotation information of the joystick, by analyzing the capacitance data. In order to realize the signal conversion of the joystick body 11 position, the main circuit board in the present invention is provided with a capacitive chip for receiving the capacitive signal from the PCB board 25, converting it, and obtaining the position information of the joystick body 11.

[0036] In the present invention, the capacitive sensor component 20 includes a case for providing a hardware support base for the entire capacitive sensor component 20, and the metal piece 23, PCB board 25 and rotating plate 24 are all provided within a cavity inside the case. Specifically, the metal piece 23 and PCB board 25 are both fixed inside the case, and the rotating plate 24 is fitted inside the case and rotates around the central axis of the rotation shaft 111.

[0037] To enable convenient assembly of the capacitive sensor component 20, the case includes a susceptor 21 and a side cover 22 that is detachably connected to the susceptor 21, and the metal piece 23, PCB board 25 and rotating plate 24 are all housed in a cavity surrounded by the susceptor 21 and the side cover 22. Specifically, the case has a first mounting space, and the side cover 22 has a second mounting space, and the first and second mounting spaces correspond to each other, forming a cavity that houses the metal piece 23, PCB board 25 and rotating plate 24. In the connection structure between the susceptor 21 and the side cover 22, a locking mechanism is provided on one of the susceptor 21 and the side cover 22, and a card slot is provided on the other of the susceptor 21 and the side cover 22. The locking mechanism snaps into the card slot, thereby allowing the susceptor 21 to be detachably connected to the side cover 22 (in this embodiment, a side cover locking mechanism 221 is provided on the side cover 22).

[0038] To enable rotational control of the rotating plate 24 and to prevent interference with the capacitive sensor component 20 during this rotation, the susceptor 21 in this invention is provided with a susceptor through hole 211, and a metal groove 231 is provided in the center of the metal piece 23. The rotating shaft 111 passes through the susceptor through hole 211 and the metal groove 231 in sequence before connecting to an axial hole 243 located in the rotating plate 24, thereby rotating the rotating plate 24.

[0039] Since the capacitive field is formed by two opposing conductive structures, in this invention, the PCB board 25 corresponding to the position of the metal piece 23 is provided with conductive pieces for forming a capacitive field corresponding to the position of the metal piece 23, and the lines on the PCB board 25 are used to receive the capacitance value between the conductive pieces and the metal piece 23 and to generate a capacitive signal. The conductive pieces here are conductive contact pieces, pads, or fingering structures provided on the PCB board 25, and the difficulty of processing the PCB board 25 is reduced by integrating the conductive pieces on the PCB board 25.

[0040] In one embodiment, both the conductive piece and the metal piece 23 are fan-shaped, and the shutter 242 of the rotating plate 24 is fan-shaped. In another embodiment, both the conductive piece and the metal piece 23 are fan-ring shaped, and the shutter 242 of the rotating plate 24 is fan-shaped or fan-ring shaped. In the embodiments shown in Figures 3 and 4, both the conductive piece and the metal piece 23 are fan-ring shaped, and the centroid angle corresponding to the fan-ring is greater than 180°, while the shutter 242 of the rotating plate 24 is fan-shaped, and the centroid angle corresponding to the fan shape is 180°.

[0041] As shown in Figures 5 and 6, the joystick body 11 may move in both left and right directions when rotating from its initial position. Therefore, considering only the change in the magnitude of the capacitance between the metal piece 23 and the conductive piece is insufficient to determine the motion state of the joystick body 11. In a preferred embodiment, the conductive piece includes a first conductive piece 2521 and a second conductive piece 2522 spaced apart from each other, the first conductive piece 2521 and the second conductive piece 2522 are fitted together and used to identify the rotation direction and rotation angle of the rotating plate 24.

[0042] Specifically, if the capacitance between the first conductive piece 2521 and the metal piece 23 decreases (or remains unchanged) relative to the capacitance value at the original position, and the capacitance between the second conductive piece 2522 and the metal piece 23 increases, the rotating plate 24 rotates in the direction where the first conductive piece 2521 is located. If the capacitance between the first conductive piece 2521 and the metal piece 23 increases relative to the capacitance value at the original position, and the capacitance between the second conductive piece 2522 and the metal piece 23 decreases (or remains unchanged), the rotating plate 24 rotates in the direction where the second conductive piece 2522 is located.

[0043] Therefore, in order to facilitate the identification of the rotation direction of the rotating plate 24, the PCB board 25 in this invention not only outputs the capacitance value between the metal piece 23 and the PCB board 25, but also outputs the amount of change in the capacitance value. That is, when the PCB board 25 outputs a capacitance value with a first amount of change (the first capacitive field capacitance increases and the second capacitive field capacitance decreases), it is indicated that the rotating plate 24 rotates to the left, and at the same time, the magnitude of the numerical value of the first amount of change indicates the range of rotation of the rotating plate 24. When the PCB board 25 outputs a capacitance value with a second amount of change (the first capacitive field capacitance decreases and the second capacitive field capacitance increases), it is indicated that the rotating plate 24 rotates to the right, and at the same time, the magnitude of the numerical value of the second amount of change indicates the range of rotation of the rotating plate 24. Correspondingly, the PCB pins 251 of the PCB board 25 include a first pin, a second pin, and a common pin. Here, the connection between the first pin and the common pin outputs data for a first capacitive field corresponding to the first conductive piece 2521, and the connection between the second pin and the common pin outputs data for a second capacitive field corresponding to the second conductive piece 2522. The mating of these three pins enables the output of an analog signal to the circuit board, thereby outputting position information of the joystick body 11 output by the PCB board 25, including directional information and specific position information.

[0044] Preferably, in the embodiments shown in Figures 5 and 6, the shielding area of ​​the rotating plate 24 is smaller than the laminated area between the metal piece 23 and the PCB board 25 so that the PCB board 25 outputs a non-zero capacitive signal value in its initial state.

[0045] A protruding metal piece positioning portion 232 is further provided in the center of the metal piece 23. This metal piece positioning portion 232 enables correspondence between the position of the metal piece 23 and the PCB board 25, while simultaneously making it easier to fix the metal piece 23 to the case.

[0046] In a preferred embodiment, two capacitive sensor components 20 are assembled to a single joystick component 10, and these two capacitive sensor components 20 are each connected to two intersecting rotation axes 111 of the joystick component 10 and used to sound rotational information of the joystick body 11 in the X and Y axes.

[0047] 3. Switch components This capacitive joystick further includes a switch component 30, which is electrically connected to a main circuit board, and the switch component 30 outputs a digital signal to the main circuit board to achieve switch control. In this invention, the switch component 30 includes a button (which may be an entity button or a pressure induction button) and a mounting part, the button being attached to the housing of the joystick component 10 by the mounting part, so that when the joystick body 11 is pressed, the button is pressed and outputs an induction signal in the Z-axis direction to the main circuit board.

[0048] To avoid the switch component 30 being affected by the output of the mechanical operation signal from the joystick component 10, the housing of the joystick component 10 is provided with space for the rotation axis 111 to move up and down.

[0049] This switch component 30 has connection pins, and the switch component 30 is attached to the main circuit board by the connection pins to enable signal transmission.

[0050] As shown in Figure 7, based on the above-mentioned game handle and capacitive joystick, the present invention further provides a game control method which detects the movement of the joystick in the joystick component 10 using a capacitive sensor component 20 and further obtains joystick position information.

[0051] This game control method includes the following steps: (1) When the lever of the joystick component 10 moves, that is, the joystick body 11 is controlled to swing the user's hand in one direction (i.e., the X axis) or two directions (i.e., the Y axis).

[0052] (2) The rotating plate 24 in the capacitive sensor component 20 is controlled to rotate at the output terminal of the joystick component 10, thereby changing the capacitance value between the metal piece 23 and the PCB board 25. Specifically, when the joystick body 11 rotates, the rotation axis 111 rotates accordingly, and when the rotating plate 24 also rotates according to the rotation axis 111, the rotation of the rotating plate 24 between the metal piece 23 and the PCB board 25 increases / decreases the exposed area of ​​the metal piece 23 relative to the rotating plate 24, thereby changing the relative stacking area between the metal piece 23 and the PCB board 25.

[0053] For example, when the joystick body 11 is moved to the left during use, the rotating plate 24 is deflected to the left, increasing the area shielded on the left side of the metal piece 23 (decreasing the exposed area) and decreasing the area shielded on the right side of the metal piece 23 (increasing the exposed area). As a result, the stacking area of ​​the metal piece 23 on the left side of the PCB board 25 decreases, and the stacking area of ​​the metal piece 23 on the right side of the PCB board 25 decreases. The reverse is also true.

[0054] (3) The shielding of the rotating plate 24 changes the stacking area between the metal piece 23 and the PCB board 25, which changes the magnitude and direction of the change in the capacitance value output by the PCB board 25, thereby providing more specific capacitance value information.

[0055] The capacitance data output by the PCB board 25 not only includes the capacitance value between the metal piece 23 and the PCB board 25, but the capacitive chip also calculates the amount of change based on this capacitance value. For example, when the joystick body 11 is moved to the left to change its position, the joystick body 11 rotates the rotating plate 24 to the left, and if the shielding area between the metal piece 23 and the first conductive piece 2521 increases, the capacitance value between the metal piece 23 and the first conductive piece 2521 is A1, and the capacitance value A1 becomes smaller than the initial value A0, and the change value is Δa (where Δa = A0 - A1), and if Δa < 0, the PCB board 25 outputs information such as "capacitance value A1", "change value Δa", and "Δa < 0".

[0056] (4) The main circuit board acquires capacitance data output from the PCB board 25 and compares it with capacitance information for the original position that is stored in advance to obtain the rotation direction and rotation angle of the rotating plate 24, as well as the position information of the control terminals in the joystick component 10 (i.e., the oscillation direction and oscillation angle of the joystick body 11).

[0057] In this invention, the main circuit board is provided with a capacitive chip that is electrically connected to the PCB board 25, receives and converts the capacitance data output by the PCB board 25 to obtain position information of the joystick body 11.

[0058] Steps (2) and (3) above describe the signal reception, analysis, and output process of one capacitive sensor component 20. When two capacitive sensor components 20 are applied, the two different output axes of the joystick component 10 are connected to the corresponding capacitive sensor components 20. Each of the two capacitive sensor components 20 acquires input signals from the control terminals of the joystick component 10 in two different directions (i.e., the X axis and the Y axis). The main circuit board receives the capacitance data from the two capacitive sensor components 20 and obtains position information of the control terminals of the joystick component 10. The two capacitive sensor components 20 perform steps (2) and (3) above synchronously, and both capacitive sensor components 20 output capacitance change information. The main circuit board can then determine the overall rotation information of the joystick component 10 in the X and Y directions.

[0059] This invention generates a signal output by non-carbon brush contact, significantly increasing the contact output life compared to conventional contact methods. This solves the problem of wear occurring after contact friction with carbon brushes, and the resulting unstable contact and drift due to residue remaining at the contact site after wear. At the same time, it occupies significantly less space than conventional non-contact signal output methods, and is not limited by mounting space. Furthermore, by shielding the metal piece 23 and PCB board 25 with the rotating plate 24, capacitive detection can be made more accurate, and the signal detection accuracy can be increased.

[0060] It should be understood that those skilled in the art may make improvements or modifications based on the above description, but all such improvements and modifications shall fall within the scope of protection of the claims attached to the present invention.

[0061] The above has provided an illustrative description of the patent for the present invention, accompanied by the attached drawings. However, it is clear that the realization of the patent for the present invention is not limited to the above-described method. Various improvements made by adopting the ideas and technical proposals of the patent for the present invention, or applying the ideas and technical proposals of the patent for the present invention directly to other cases without modification, are all within the scope of protection of the present invention.
