Description

Capacitive joystick, game controller, and game control method Technical Field

[0001] The present invention relates to the technical field of electronic equipment, and in particular to a capacitive joystick, a game controller, and a game control method. Background Art

[0002] As living standards improve, joysticks are increasingly used in games. Recognizing joystick motions is a critical technical aspect of game controllers, and thin-film resistor joysticks are a widely used type. Conventional thin-film resistor joysticks, however, suffer from process limitations and a short service life. Furthermore, friction between the spring and the thin-film resistor causes carbon particle adsorption, which can lead to drift and poor performance stability. Hall effect joysticks have emerged to address these issues, but their high power consumption makes them unsuitable for low-power applications.

[0003] To address the short lifespan and poor stability of thin-film resistor rockers and the high power consumption of Hall effect rockers, capacitive rocker devices are currently available. For example, patent publication number CN 105224103 A discloses a capacitive rocker device that detects the movement of an operating lever using a capacitive sensor to generate a detection signal. However, the capacitance detection accuracy of this structure is very low, and due to the space limitations of the rocker structure, this structure is difficult to implement. In addition, even if two electrodes are directly aligned and capacitance detection is performed, the distance between the two electrodes makes it difficult to detect slight position changes between the two electrodes, resulting in low sensitivity in detecting rocker movement. Furthermore, due to the space limitations of the rocker structure, it is difficult to provide sufficient space for the electrodes to move, making this type of rocker difficult to implement.

[0004] The above defects are worth solving. Summary of the Invention

[0021] The present invention according to the above scheme is characterized in that the output ends of the two different directions of the rocker assembly are respectively connected to the corresponding capacitive sensing components, and the two capacitive sensing components respectively obtain the input signals of the control end in two different directions in the rocker assembly, and the main circuit board obtains the capacitance data of the two capacitive sensing components and obtains the position information of the control end in the rocker assembly.

[0022] The present invention according to the above scheme has the following beneficial effects:

[0036] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0037] As shown in Figures 1 to 6, to overcome the shortcomings of traditional thin-film resistor joysticks, such as short lifespan and drift, and Hall effect joysticks with high power consumption, the present invention proposes a game controller comprising a controller body with a capacitive joystick mounted thereon. This capacitive joystick is contactless, minimizing wear and tear and drift. Furthermore, the change in capacitance is used to determine the joystick's position, improving the accuracy of joystick position detection.

[0038] The capacitive joystick includes a joystick assembly 10 and a capacitive sensing assembly 20, wherein the joystick assembly 10 is used to obtain human operating actions and output mechanical action signals based on the actions, and the capacitive sensing assembly 20 is used to output capacitive signals according to the mechanical action signals of the joystick assembly 10 and send them to the main circuit board for data analysis to obtain the position signal of the joystick.

[0039] 1. Joystick assembly

[0040] The rocker assembly 10 has a control end and at least one output end, and the output end is connected to the rotating shaft 111, wherein the control end is used to accept human control, and the output end is used to output a mechanical action signal.

[0041] Specifically, the joystick assembly 10 includes a housing, a joystick body 11 assembled within the housing, and a rotating portion. The housing serves as the support base for the entire joystick assembly 10 and can be mounted directly on the main circuit board or elsewhere on the game controller. Specifically, when the joystick assembly 10 is mounted directly on the main circuit board, the housing of the joystick assembly 10 has mounting feet, which are used to mount the housing to the main circuit board.

[0042] The rocker body 11 has at least two ends, one of which is a control end for receiving human control actions, and the other end extends into the shell and is connected to the rotating part; the rotating part is used to be controlled by the other end of the rocker body 11 and output a mechanical action signal. The rotating part has an output end for controlling the capacitive sensing component 20.

[0043] In a preferred embodiment, since the rocker body 11 in the rocker assembly 10 is mostly omnidirectionally rotatable, the rotating part in the present invention includes a first rotating shaft and a second rotating shaft. The second rotating shaft is sleeved in the first rotating shaft to form a universal joint, and the rocker body 11 passes through the first rotating shaft and is connected to the second rotating shaft.

[0044] To enable full-range rotation of the rocker body 11, a first swing track is provided within the first rotating shaft, and a second swing track is provided within the second rotating shaft. The first and second swing tracks intersect (preferably, they are two perpendicular intersecting planes). The first rotating shaft has a first axis, which is hingedly connected to the housing and allows the first rotating shaft, the second rotating shaft, and the rocker body 11 to swing within a first plane. The second rotating shaft has a second axis, which passes through the first rotating shaft and is hingedly connected to the housing and allows the second rotating shaft and the rocker body 11 to swing within a second plane. The present invention achieves full-range rotation of the rocker body 11 through the interaction between the first rotating shaft, the second rotating shaft, the rocker body 11, and the housing.

[0045] Of course, in other embodiments, the rocker body 11 can also achieve omnidirectional rotation through rotating parts of other structures, and the present invention is not limited thereto.

[0046] In addition, the present invention can also meet the requirement of rotating the rocker body 11 within a plane. Here, the rotating portion can further adopt a universal joint structure, and the rocker body 11 rotates within the swing track of the universal joint to realize the motion output of the rotating shaft 111 of the rocker body 11. Of course, the rocker body 11 can also be directly configured to form the rotating shaft 111, and the rotating shaft 111 serves as the output of the mechanical action signal. That is, the rocker body 11 has both a control end and an output end.

[0047] The rocker assembly 10 also includes a reset member located within the housing and configured to provide restoring force to the rocker body 11. Specifically, a base plate is provided below the housing, and the housing and base plate are snap-fitted together (not shown). One end of the reset member abuts the base plate at the bottom of the housing, while the other end abuts the rocker body 11. This allows downward pressure on the rocker body 11 to cause the reset member to compress. When the downward pressure on the rocker body 11 is removed, the reset member resets the rocker body 11. Preferably, the reset member can be a spring.

[0048] 2. Capacitive sensing components

[0049] The capacitive sensing component 20 in the present invention includes at least one, and the capacitive sensing component 20 is connected to the rotating shaft 111 of the rocker component 10. When there are two or more capacitive sensing components 20, each capacitive sensing component 20 is respectively connected to a rotating shaft 111 of the rocker component 10.

[0050] Each capacitive sensing assembly 20 includes a rotating plate 24, a metal sheet 23, and a PCB 25, which are spaced apart and form a capacitance field. The metal sheet 23 and PCB 25 are spaced apart to form a capacitance field. The rotating plate 24 is connected to the rotating shaft 111 and positioned between the metal sheet 23 and PCB 25. Under normal conditions, the capacitance field between the metal sheet 23 and PCB 25 is interrupted by the rotating plate 24. However, as the rotating plate 24 rotates with the rotating shaft 111, it changes the overlapped area between the metal sheet 23 and PCB 25, causing a change in the capacitance between the two. Consequently, the rotation of the rotating plate 24 can be detected by measuring the capacitance between the metal sheet 23 and PCB 25.

[0051] The rotating plate 24 includes 241 and a baffle 242. 241 is connected to the rotating shaft 111, wherein 241 is used to receive the drive of the rotating shaft 111 to drive the baffle 242 to rotate. The baffle 242 is used to shield the metal sheet 23 and the PCB board 25 to achieve a change in the capacitance field between the two. Preferably, 241 has an axial hole 243, and 241 is connected to the rotating shaft 111 through the axial hole 243. The axial hole 243 can be a non-circular hole so that when the rotating shaft 111 rotates, 241 is also driven. The rotating plate 24 in the present invention is preferably made of an insulating material, such as plastic, ceramic, etc., to avoid affecting the capacitance field between the metal sheet 23 and the PCB board 25.

[0052] Furthermore, the PCB 25 is connected to the main circuit board. After measuring the capacitance between the PCB 25 and the metal sheet 23, the PCB 25 transmits this capacitance data to the main circuit board. The main circuit board calculates and outputs data changes based on the capacitance changes (this data change includes voltage and current changes). Specifically, the main circuit board analyzes this capacitance data to obtain rotation information of the rotating plate 24, i.e., the rotation information of the joystick. To achieve signal conversion of the position of the joystick body 11, a capacitor chip is provided on the main circuit board in the present invention. The capacitor chip is used to receive the capacitance signal from the PCB 25 and convert it into position information of the joystick body 11.

[0053] In the present invention, the capacitive sensing assembly 20 includes a housing, which is used to provide a hardware support foundation for the entire capacitive sensing assembly 20. The metal sheet 23, the PCB board 25, and the rotating plate 24 are all arranged in a cavity inside the housing. Specifically, the metal sheet 23 and the PCB board 25 are both fixed in the housing, and the rotating plate 24 is inserted into the housing and rotates around the central axis of the rotating shaft 111.

[0054] To facilitate assembly of the capacitive sensing assembly 20, the housing includes a base 21 and a side cover 22 detachably connected to the base 21. The metal sheet 23, PCB board 25, and rotating plate 24 are all located within the cavity enclosed by the base 21 and the side cover 22. Specifically, the housing has a first installation space, and the side cover 22 has a second installation space. The first installation space and the second installation space correspond to each other, forming a cavity for accommodating the metal sheet 23, PCB board 25, and rotating plate 24. In the connection structure between the base 21 and the side cover 22, a buckle is provided on one of the base 21 and side cover 22, and a slot is provided on the other of the base 21 and side cover 22. The buckle and the slot are engaged and connected, allowing the base 21 and side cover 22 to be detachably connected (in this embodiment, a side cover buckle 221 is provided on the side cover 22).

[0055] In order to achieve rotation control of the rotating plate 24 and avoid affecting the capacitive sensing component 20 during the rotation process, a base through-hole 211 is provided on the base 21 of the present invention, and a metal sheet middle groove 231 is provided in the middle of the metal sheet 23. The rotating shaft 111 passes through the base through-hole 211 and the metal sheet middle groove 231 in sequence and is connected to the shaft hole 243 located on the rotating hole plate to drive the rotating plate 24 to rotate.

[0056] Because a capacitive field is formed by two opposing conductive structures, a conductive sheet is provided on the PCB 25 in the present invention, corresponding to the metal sheet 23. The conductive sheet and the metal sheet 23 correspond to form a capacitive field, and the circuitry on the PCB 25 is used to receive the capacitive field between the conductive sheet and the metal sheet 23 and generate a capacitive signal. The conductive sheet here refers to a conductive contact, pad, or gold finger structure provided on the PCB 25. By integrating the conductive sheet on the PCB 25, the difficulty of manufacturing the PCB 25 is reduced.

[0057] In one embodiment, the conductive sheet and the metal sheet 23 are both fan-shaped, and the baffle 242 of the rotating plate 24 is fan-shaped. In another embodiment, the conductive sheet and the metal sheet 23 are both fan-shaped, and the baffle 242 of the rotating plate 24 is fan-shaped or fan-shaped. In the embodiments shown in Figures 3 and 4, the conductive sheet and the metal sheet 23 are both fan-shaped, and the central angle of the fan-shaped circle is greater than 180°, while the baffle 242 of the rotating plate 24 is fan-shaped, and the central angle of the fan-shaped circle is 180°.

[0058] As shown in Figures 5 and 6, since the rocker body 11 has the possibility of moving in both left and right directions when rotating from the initial position, it is not sufficient to only consider the change in the capacitance value between the metal sheet 23 and the conductive sheet to determine the motion state of the rocker body 11. Therefore, in a preferred embodiment, the conductive sheet includes a first conductive sheet 2521 and a second conductive sheet 2522 that are spaced apart from each other. The first conductive sheet 2521 and the second conductive sheet 2522 cooperate with each other to identify the rotation direction and rotation angle of the rotating plate 24.

[0059] Specifically, when the capacitance between the first conductive sheet 2521 and the metal sheet 23 decreases (or remains unchanged) and the capacitance between the second conductive sheet 2522 and the metal sheet 23 increases relative to the original position, the rotating plate 24 rotates toward the direction of the first conductive sheet 2521; when the capacitance between the first conductive sheet 2521 and the metal sheet 23 increases and the capacitance between the second conductive sheet 2522 and the metal sheet 23 decreases (or remains unchanged) relative to the original position, the rotating plate 24 rotates toward the direction of the second conductive sheet 2522.

[0060] Therefore, the PCB board 25 of the present invention not only outputs the capacitance value between the metal sheet 23 and the PCB board 25, but also outputs the change in capacitance value, thereby identifying the rotation direction of the rotating plate 24. Specifically, when the PCB board 25 outputs a capacitance value of a first change (increase in the first capacitance field capacitance and decrease in the second capacitance field capacitance), it indicates that the rotating plate 24 is rotating to the left, and the magnitude of the first change indicates the amplitude of the rotation of the rotating plate 24. When the PCB board 25 outputs a capacitance value of a second change (decrease in the first capacitance field capacitance and increase in the second capacitance field capacitance), it indicates that the rotating plate 24 is rotating to the right, and the magnitude of the second change indicates the amplitude of the rotation of the rotating plate 24. Accordingly, the PCB pins 251 of the PCB board 25 include a first pin, a second pin, and a common pin. The first pin and the common pin output data corresponding to the first capacitance field of the first conductive plate 2521, and the second pin and the common pin output data corresponding to the second capacitance field of the second conductive plate 2522. The three pins cooperate with each other to output analog signals to the circuit board, so that the PCB board 25 can output the position information of the joystick body 11 including direction information and specific position information.

[0061] Preferably, in the embodiments shown in FIG5 and FIG6, the shielding area of ​​the rotating plate 24 is smaller than the overlapping area between the metal sheet 23 and the PCB board 25, so that the PCB board 25 outputs a non-zero capacitance signal value in the initial state.

[0062] A protruding metal sheet positioning portion 232 is further provided in the middle of the metal sheet 23 , through which the metal sheet 23 and the PCB board 25 are aligned, and the metal sheet 23 can be more conveniently fixed to the housing.

[0063] In a preferred embodiment, a rocker assembly 10 is equipped with two capacitive sensing assemblies 20, and the two capacitive sensing assemblies 20 are respectively connected to two mutually intersecting rotating shafts 111 of the rocker assembly 10 to detect the rotation information of the rocker body 11 in the X and Y axes.

[0064] 3. Switch assembly

[0065] The capacitive joystick also includes a switch assembly 30, which is electrically connected to the main circuit board and outputs digital signals to the main circuit board to achieve on-off control. In the present invention, the switch assembly 30 includes a button (which can be a physical button or a pressure-sensitive button) and an assembly. The button is mounted on the housing of the joystick assembly 10 via the assembly. Pressing the joystick body 11 downward activates the button, which then outputs a sensing signal in the Z-axis direction to the main circuit board.

[0066] In order to prevent the switch assembly 30 from affecting the mechanical action signal output by the rocker assembly 10 , a space is provided on the housing of the rocker assembly 10 for the rotating shaft 111 to move up and down.

[0067] The switch assembly 30 has connecting pins, and the switch assembly 30 is mounted on the main circuit board through the connecting pins to achieve signal transmission.

[0068] As shown in FIG7 , based on the above-mentioned game controller and capacitive joystick, the present invention further provides a game control method, which detects the movement of the joystick in the joystick assembly 10 through the capacitive sensing component 20 to obtain the information of the joystick position.

[0069] The game control method comprises the following steps:

[0070] (1) When the rod of the rocker assembly 10 moves, the rocker body 11 is controlled by the user's hand to swing in one direction (i.e., the X-axis) or two directions (i.e., the Y-axis).

[0071] (2) The rotating plate 24 in the capacitive sensor assembly 20 is controlled by the output end of the rocker assembly 10 to rotate, causing the capacitance value between the metal sheet 23 and the PCB board 25 to change. Specifically, when the rocker body 11 rotates, the rotating shaft 111 rotates accordingly, and the rotating plate 24 rotates along with the rotating shaft 111. At this time, the rotating plate 24 rotates between the metal sheet 23 and the PCB board 25, causing the exposed area of ​​the metal sheet 23 relative to the rotating plate 24 to increase / decrease, thereby changing the relative overlapping area between the metal sheet and the capacitor plate.

[0072] For example, during use, if the joystick body 11 is moved to the left, the rotating plate 24 deflects to the left, increasing the blocked area on the left side of the metal sheet 23 (decreasing the exposed area) and decreasing the blocked area on the right side of the metal sheet 23 (increasing the exposed area). This results in a reduced overlap area on the left side of the metal sheet 23 relative to the PCB 25, while a reduced overlap area on the right side of the metal sheet 23 relative to the PCB 25. The reverse is also true.

[0073] (3) The area between the metal sheet 23 and the PCB board 25 is changed by the rotating plate 24, so that the capacitance value output by the PCB board 25 and the direction of the change change change, thereby obtaining specific capacitance value information.

[0074] The capacitance data output by the PCB 25 includes not only the capacitance value between the metal sheet 23 and the PCB 25, but also the capacitance chip's calculation of the capacitance change based on this capacitance value. For example, when the joystick body 11 is moved to the left, causing it to change position, the joystick body 11 drives the rotating plate 24 to rotate to the left, thereby increasing the area blocked between the metal sheet 23 and the first conductive sheet 2521. At this point, the capacitance value between the metal sheet 23 and the first conductive sheet 2521 is A1. This capacitance value A1 decreases relative to the initial value A0 by a change of Δa (where Δa = A0 - A1), and Δa < 0. The PCB 25 then outputs information such as "capacitance value A1," "change of Δa," and "Δa < 0."

[0075] (4) The main circuit board obtains the capacitance data output by the PCB board 25, compares it with the capacitance information at the pre-stored original position, and rotates the plate 24 in the direction and angle of rotation to obtain the position information of the control end in the rocker assembly 10 (i.e., the swing direction and swing angle of the rocker body 11).

[0076] In the present invention, a capacitor chip is provided on the main circuit board. The capacitor chip is electrically connected to the PCB board 25 and is used to receive capacitance data output by the PCB board 25 and convert it into position information of the joystick body 11 .

[0077] The above steps (2) to (3) are the signal receiving, analyzing, and outputting processes of a capacitive sensing component 20. When two capacitive sensing components 20 are used, the two different output axes of the rocker assembly 10 are connected to the corresponding capacitive sensing components 20 respectively. The two capacitive sensing components 20 respectively obtain the input signals of the control end in two different directions (i.e., the X-axis and the Y-axis) of the rocker assembly 10, the capacitance data of the two capacitive sensing components 20 of the main circuit board, and the position information of the control end in the rocker assembly 10. The two capacitive sensing components 20 synchronously perform the above steps (2) to (3). Both capacitive sensing components 20 output capacitance change information, and the main circuit board can determine the comprehensive rotation information of the rocker assembly 10 in the X and Y directions.

[0078] The present invention utilizes non-brush contact to generate signal output, significantly increasing the lifespan of conventional contact outputs. This solves the problem of traditional carbon brush contact, which causes wear and tear, and residue at the contact site, leading to unstable contact and drift. Furthermore, compared to existing non-contact signal output methods, this method occupies significantly less space, unrestricted by installation space. Furthermore, by shielding the metal sheet 23 and PCB 25 with the rotating plate 24, capacitance detection is more accurate, resulting in higher signal detection precision.

[0079] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the appended claims of the present invention.

[0080] The above is an exemplary description of the patent of the present invention in conjunction with the accompanying drawings. It is obvious that the implementation of the patent of the present invention is not limited to the above-mentioned method. As long as various improvements are made by adopting the method concept and technical solution of the patent of the present invention, or the concept and technical solution of the patent of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
