Description

Technical Field

[0001] This invention relates to the field of electronic devices, and in particular to a joystick device and a game controller. Background Technology

[0002] With the improvement of living standards, people's leisure activities are becoming increasingly rich, and joysticks are being used more and more frequently in games. Among related technologies, conventional thin-film resistor joysticks are limited in lifespan due to manufacturing limitations, generally around two million cycles. Furthermore, during use, carbon particle adsorption caused by friction between the spring and the thin-film resistor can easily lead to drift issues, resulting in poor performance stability and drawing considerable criticism from users. To address these problems, Hall effect joysticks have emerged on the market. However, Hall effect joysticks have higher power consumption, making them unsuitable for low-power products, and their higher cost reduces their market competitiveness. Summary of the Invention

[0003] The main objective of this invention is to provide a joystick device and game controller that aims to improve the lifespan and performance stability of the joystick, while also having lower power consumption and cost.

[0004] To achieve the above objectives, the present invention provides a rocker arm device comprising:

[0005] case;

[0006] The joystick is movably connected to the housing.

[0007] The sensing assembly includes a conductive element and a sensor coil spaced apart along a first direction. The conductive element is disposed on the rocker arm and can move with the rocker arm. The sensor coil remains fixed relative to the housing.

[0008] A control component is electrically connected to the sensing component and outputs an electrical signal to the sensor coil. When the rocker arm moves, the overlapping area of ​​the conductive element and the sensor coil in the first direction changes, so that the electromagnetic signal of the sensor coil changes accordingly. The control component is used to generate corresponding rocker arm action information based on the electromagnetic signal of the sensor coil.

[0009] Optionally, the sensor coils are configured as a plurality of coils, which are spaced apart along the movement trajectory of the conductive element.

[0010] The control component is electrically connected to the plurality of sensor coils respectively, and is used to output electrical signals to the plurality of sensor coils;

[0011] When the rocker arm moves, the overlapping area of ​​the conductive element and at least one of the sensor coils relative to each other in the first direction changes, causing a corresponding change in the electromagnetic signal of at least one of the sensor coils.， The control component is used to generate corresponding joystick action information based on the electromagnetic signals from the multiple sensor coils.

[0012] Optionally, under the action of the rocker arm, the conductive element and the sensor coil can rotate relative to each other or move linearly.

[0013] Optionally, the sensor coil is configured as a square coil, a circular coil, or an irregularly shaped coil.

[0014] Optionally, the conductive element includes an FPC or a steel sheet.

[0015] Optionally, the rocker includes a rocker handle and a rotating structure, the rotating structure having a pivot, the rocker handle being rotatably connected to the housing via the rotating structure, and the conductive element being connected to the pivot of the rotating structure.

[0016] Optionally, the rocker arm device further includes an angle detection sensor, which includes a fixed member and a movable member. The movable member is connected to the rotating shaft of the rotating structure and can rotate relative to the fixed member. The conductive member is disposed on the movable member, and the sensor coil is disposed on the fixed member.

[0017] Optionally, the rotating structure includes an X-axis and a Y-axis that are perpendicular to each other. Two angle detection sensors are provided, one of which is connected to the X-axis and the other is connected to the Y-axis. Each angle detection sensor is provided with a set of sensing components.

[0018] Optionally, the control component includes a touch chip and a main control element that are electrically connected to each other, and the sensor coil is electrically connected to the touch chip;

[0019] The touch chip is used to send the electromagnetic signal from the sensor coil to the main control element, and the main control element is used to process the electromagnetic signal to generate the joystick action information.

[0020] Optionally, the sensing components are multiple sets arranged at intervals, and the control component is electrically connected to each of the sensing components.

[0021] The present invention also proposes a game controller, including any of the joystick devices described above.

[0022] The technical solution of this invention involves setting up a conductive element and a sensor coil. When the sensor and the conductive element are relatively overlapped along a first direction, an inductance is generated. The conductive element is connected to a rocker arm. Thus, when the rocker arm moves, the conductive element and the sensor coil move relative to each other, changing the overlap area of ​​the conductive element and the sensor coil in the first direction. This causes a corresponding change in the electromagnetic signal of the sensor coil. The control component processes the electromagnetic signal to obtain the rocker arm's motion information. Compared to traditional carbon film rockers, the rocker arm device of this invention can achieve rocker arm motion detection in a non-contact manner, eliminating contact wear issues and effectively extending the rocker arm's lifespan. It also eliminates the carbon particle adsorption problem caused by friction between the spring and the thin-film resistor, preventing rocker arm drift and effectively improving the rocker arm's performance stability. Furthermore, compared to Hall effect rockers, the rocker arm device of this invention uses electromagnetic induction for rocker arm motion detection, resulting in lower power consumption and lower cost, effectively enhancing the product's market competitiveness.

[0037] The present invention proposes a rocker arm device 100.

[0038] Please refer to Figures 1 to 6In one embodiment of the present invention, the rocker device 100 includes a housing 10, a rocker arm 20, a sensing component 30, and a control component 50. The rocker arm 20 is movably connected to the housing 10; the sensing component 30 includes a conductive element 32 and a sensor coil 31 spaced apart along a first direction. The conductive element 32 is disposed on the rocker arm 20 and can move with the rocker arm 20, while the sensor coil 31 remains fixed relative to the housing 10; the control component 50 is electrically connected to the sensing component 30 and outputs an electrical signal to the sensor coil 31; when the rocker arm 20 moves, the overlapping area of ​​the conductive element 32 and the sensor coil 31 in the first direction changes, causing a corresponding change in the electromagnetic signal of the sensor coil 31. The control component 50 is used to generate corresponding rocker arm action information based on the electromagnetic signal of the sensor coil 31.

[0039] Optionally, the housing 10 forms the main support structure of the rocker arm device 100 and can be made of insulating materials such as plastic. The shape of the housing 10 can be designed as square, spherical, or other shapes according to actual needs, and is not specifically limited here. There are various ways in which the rocker arm 20 and the housing 10 can be movably connected. For example, the rocker arm 20 and the housing 10 can be rotatably connected, so that the rocker arm 20 can rotate relative to the housing 10; another example is that the rocker arm 20 and the housing 10 can be slidably connected, so that the rocker arm 20 can slide relative to the housing 10; yet another example is that the rocker arm 20 and the housing 10 are connected by a composite connection structure, so that the rocker arm 20 can both rotate and slide relative to the housing 10. The sensing component 30 includes conductive elements 32 and sensor coils 31 spaced apart along a first direction. The sensor coil 31 generates a high-frequency magnetic field through rapid charging and discharging. When the conductive element 32 approaches this magnetic field, eddy currents are generated inside the metal object, causing the magnetic field energy to attenuate. As the conductive element 32 continuously approaches the sensing surface of the sensor coil 31, energy is absorbed, leading to attenuation and affecting the inductance value of the sensor coil 31. This triggers the sensor to output an electromagnetic signal. The control component 50 generates corresponding joystick action information based on the electromagnetic signal from the sensor coil 31, thereby achieving non-contact detection. When the joystick 20 moves, a relative displacement occurs between the sensor coil 31 and the conductive element 32, causing a change in their overlapping area. The size of the overlapping area affects the inductance value of the sensor coil 31, and consequently, the output value of the sensor chip. It should be noted that the overlapping area refers to the area of ​​the sensor coil 31 and the conductive element 32 directly opposite each other along the first direction.

[0040] Based on the principle of inductive sensing, when the overlapping area of ​​the sensor coil 31 and the conductive element 32 changes, the inductance of the sensor coil 31 changes, thereby generating a corresponding electromagnetic signal. The control component 50 processes the electromagnetic signal to obtain the motion information of the joystick 20. Furthermore, buttons can be added according to product requirements. These buttons can be located inside or outside the housing 10, and buttons can be removed from some products that do not require button functionality.

[0041] The technical solution of this invention, by setting a conductive element 32 and a sensor coil 31, generates inductance when the sensor and the conductive element are relatively overlapped along a first direction. The conductive element 32 is connected to the rocker arm 20. Thus, when the rocker arm 20 moves, the conductive element 32 and the sensor coil 31 move relative to each other, thereby changing the overlap area of ​​the conductive element 32 and the sensor coil 31 in the first direction. The electromagnetic signal of the sensor coil 31 changes accordingly. The control component 50 processes the electromagnetic signal to obtain the motion information of the rocker arm 20. Compared to traditional carbon film rocker arms 20, the rocker arm device 100 of this invention can achieve rocker arm 20 motion detection in a non-contact manner, eliminating the problem of contact wear and effectively improving the service life of the rocker arm 20. It also eliminates the problem of carbon particle adsorption caused by friction between the spring and the thin-film resistor, preventing rocker arm 20 drift and effectively improving the performance stability of the rocker arm 20. Furthermore, compared to Hall effect rockers, the rocker device 100 of the present invention uses electromagnetic induction to detect the rocker 20's movement, resulting in lower power consumption and lower cost, which can effectively enhance the product's competitive advantage in the market.

[0042] In one embodiment, the conductive element 32 can be an FPC (Flexible Printed Circuit) or a steel sheet, which has a simple structure, small size, and high sensitivity.

[0043] It should be noted that there are various ways in which the sensor coil 31 and the conductive element 32 can move relative to each other. In one embodiment, the sensor coil 31 and the conductive element 32 can rotate relative to each other under the action of the rocker arm 20. For example... Figures 1 to 4 As shown, when the rocker arm 20 rotates relative to the housing 10, the rocker arm 20 drives the conductive element 32 to rotate at a certain angle, which in turn causes the conductive element 32 to rotate relative to the sensor coil 31, thus changing the overlapping area of ​​the conductive element 32 and the sensor coil 31.

[0044] In another embodiment, the conductive element 32 and the sensor coil 31 can undergo relative linear motion under the action of the rocker arm 20. Taking the connection between the conductive element 32 and the rocker arm 20 as an example, when the rocker arm 20 slides relative to the housing 10, the rocker arm 20 drives the conductive element 32 to move linearly, thereby causing the conductive element 32 to translate linearly relative to the sensor coil 31. This changes the overlapping area of ​​the conductive element 32 and the sensor coil 31, and correspondingly changes the inductance value of the sensor coil 31.

[0045] It should be noted that the conductive component 32 is made of a conductive material. This conductive material includes, but is not limited to, metallic conductive materials such as copper, steel, and aluminum, or it may also be made of polymer conductive materials such as graphene.

[0046] In one embodiment, multiple sensor coils 31 are provided, and the multiple sensor coils 31 are spaced apart along the movement trajectory of the conductive element 32; the control component 50 is electrically connected to the multiple sensor coils 31 respectively, and is used to output electrical signals to the multiple sensor coils 31; when the rocker arm 20 moves, the overlapping area of ​​the conductive element 32 and at least one sensor coil 31 relative to each other in the first direction changes, so that the electromagnetic signal of at least one sensor coil 31 changes accordingly, and the control component 50 is used to generate corresponding rocker arm action information based on the electromagnetic signals of the multiple sensor coils 31.

[0047] Optionally, multiple sensor coils 31 can be spaced out, such as two, three, four, or more. The specific number is not limited and can be designed based on the detection sensitivity and the internal space of the housing 10. The conductive element 32 is sheet-shaped, and its dimensions along the movement trajectory can be designed as a prism shape with smaller edges and a larger center. This allows the inductance and capacitance of the sensor coil 31 to gradually change as the conductive sheet moves with the rocker arm 20, resulting in more accurate detection of the rocker arm 20's rotation. The shape of the conductive element 32 is not strictly limited; as long as the overlap area between the sensor coil 31 and the conductive element 32 changes as the conductive element moves with the rocker arm 20, the inductance of the sensor coil 31 will change.

[0048] In this embodiment, four sensor coils 31 are spaced apart. The conductive element 32 is designed to overlap with any two adjacent inductor coils along a first direction. When the rocker arm 20 rotates the conductive element 32, the overlap area between the conductive element 32 and any one of the inductor coils along the first direction changes, correspondingly changing the inductance value of that inductor coil. When the guide rod rotates the conductive element 32, the overlap area between the conductive element 32 and any two adjacent sensor coils 31 changes, meaning the inductance values ​​of the two adjacent sensor coils change. The control component 50 generates a corresponding rocker arm 20 action signal based on the electromagnetic signals of the corresponding two sensor coils 31. Compared to a single-channel system, this solution solves the problem of touch signal jumps caused by temperature changes and signal interference on the board, improving system stability.

[0049] Furthermore, the four spaced-apart sensor coils 31 are sequentially defined as the first coil 31a, the second coil 31b, the third coil 31c, and the fourth coil 31d, as follows: Figure 2 When the sensing component 30 is in the first state, the conductive element 32 partially overlaps with both the second coil 31b and the third coil 31c, causing a change in the inductance values ​​of the second coil 31b and the third coil 31c. Figure 3 When the sensing component 30 is in the second state, the conductive element 32 simultaneously overlaps with a portion of the first coil 31a and the second coil 31b, causing a change in the inductance values ​​of the first coil 31a and the second coil 31b. For example... Figure 4 When the sensing component 30 is in the third state, the conductive element 32 partially overlaps with both the third coil 31c and the fourth coil 31d, causing a change in the inductance values ​​of the third coil 31c and the fourth coil 31d. As the rotation angle of the joystick 20 changes, the overlapping area of ​​the conductive element 32 with the first coil 31a, the second coil 31b, the third coil 31c, and the fourth coil 31d changes, thereby causing a change in the inductance values ​​of the first coil 31a, the second coil 31b, the third coil 31c, and the fourth coil 31d, and outputting a corresponding electromagnetic signal to detect the movement of the joystick 20.

[0050] It should be noted that in other embodiments, the conductive element 32 may also be stacked with three or more adjacent sensor coils 31 at the same time, and this is not limited to each one.

[0051] The sensor coil 31 can be a square coil, a circular coil, or an irregularly shaped coil. Here, the inductance of the sensor coil 31 changes primarily based on the overlapping area of ​​the conductive element 32 in the first direction, and the corresponding inductance signal is output to the control component 50. Its shape is not limited here, as long as the inductance value of the sensor coil 31 changes when the rocker arm 20 moves the conductive element 32, and the corresponding electromagnetic signal is output to the control component 50.

[0052] Please refer to Figure 1 In one embodiment, the rocker arm 20 includes a rocker arm handle 21 and a rotating structure 22. The rocker arm handle 21 is rotatably connected to the housing 10 through the rotating structure 22, and the conductive element 32 is connected to the rotating shaft 221 of the rotating structure 22.

[0053] In this embodiment, when the user operates the joystick handle 21, the joystick handle 21 can rotate relative to the housing 10 via the rotating structure 22. The rotating structure 22 can be configured as a hinge, universal joint, or other structure as needed. The rotating structure 22 has a rotating shaft 221, and a conductive element 32 is connected to the rotating shaft 221. The sensor coil 31 remains fixed relative to the housing 10, and the joystick handle 21 can drive the rotating shaft 221 of the rotating structure 22 to rotate relative to the housing 10, thereby achieving relative rotation between the conductive element 32 and the sensor coil 31. When there is only one sensor coil 31 (single-channel angle sensor), the overlapping area of ​​the conductive element 32 and the sensor coil 31 differs depending on the rotation angle, thus changing the inductance of the sensor coil 31 and altering its output electromagnetic signal, thereby detecting the rotation of the joystick 20. When there are four sensor coils 31 spaced apart (four-channel angle sensor), such as... Figure 2-5 As shown, depending on the rotation angle, the overlapping area of ​​the conductive element 32 and the two adjacent sensor coils 31 is different, which in turn changes the inductance of the two adjacent sensor coils 31. The electromagnetic signals output by the two sensor coils 31 will change, which can also realize the rotation detection of the joystick 20.

[0054] In one embodiment, the rocker arm device 100 further includes an angle detection sensor 40, which includes a fixed member and a movable member. The movable member is connected to the rotating shaft 221 of the rotating structure 22 and can rotate relative to the fixed member. The conductive member 32 is disposed on the movable member, and the sensor coil 31 is disposed on the fixed member.

[0055] In this embodiment, the angle detection sensor 40 can detect the rotation angle of the rocker arm 20 through the cooperation of a movable part and a fixed part. For example, the movable part is a gear connected to the rotating shaft 221 of the rotating structure 22, and the fixed part is a friction plate located on one side of the gear. The rotating shaft 221 of the rotating structure 22 drives the gear to rotate, and the friction plate cooperates with the gear to collect the generated electrical signal, thereby realizing the detection of the rotation angle of the rocker arm 20. When the rotating shaft 221 of the rotating structure 22 drives the movable part of the angle detection sensor 40 to rotate, it can drive the conductive part 32 to rotate together, thereby realizing the relative rotation between the conductive part 32 and the sensor coil 31. In this embodiment, by integrating the conductive part 32 and the sensor coil 31 onto the angle detection sensor 40, the overall structure is more compact, which is more conducive to the miniaturization of the overall product size.

[0056] Furthermore, the rotating structure 22's rotation axis 221 includes mutually perpendicular X-axis and Y-axis rotation axes. Two angle detection sensors 40 are provided, one connected to the X-axis and the other connected to the Y-axis. Each angle detection sensor 40 is equipped with a set of sensing components 30. In this embodiment, by providing two angle detection sensors 40, the X-axis and Y-axis rotation angles of the joystick 20 can be detected separately. Simultaneously, each angle detection sensor 40 is equipped with a set of sensing components 30, which can detect the X-axis and Y-axis movements of the joystick 20, thereby improving the overall detection sensitivity of the joystick device 100.

[0057] like Figure 6 As shown, based on the above embodiment, the control component 50 includes a touch chip 51 and a main control element 52 that are electrically connected to each other, and the sensor coil 31 is electrically connected to the touch chip 51; the touch chip 51 is used to send the sensing signal output by the sensor coil 31 to the main control element 52, and the main control element 52 is used to process the sensing signal to generate the action information of the joystick 20.

[0058] Specifically, the touch chip 51 has a receiving channel (RX), and the sensor coil 31 is connected to the receiving channel (RX). When there are multiple sensor coils 31 arranged at intervals, the touch chip 51 has correspondingly multiple receiving channels (RX), such as... Figure 2-4As shown, taking four sensor coils 31 spaced apart as an example, the touch chip 51 has a corresponding receiving channel (RX) connected to each sensor coil 31. When the joystick 20 moves, the inductance values ​​of two of the sensor coils 31 change, and their output electromagnetic signals change accordingly. The touch chip 51 sends the electromagnetic signals to the main control element 52 (e.g., MCU), and then the main control element 52 can perform data fitting on the electromagnetic signals according to a preset program or algorithm to generate the motion information of the joystick 20.

[0059] In one embodiment, the sensing components 30 are arranged in multiple groups at intervals, and the control component 50 is electrically connected to each of the sensing components 30.

[0060] Optionally, the sensing component 30 can be arranged in two, three, four, or more groups at intervals, without limitation. In this embodiment, two groups of sensing components 30 arranged at intervals are used as an example for explanation (not shown in the figure), which are defined as the first sensing component and the second sensing component, respectively. Correspondingly, the first sensing component includes a first conductive element and a first sensor coil, and the second sensing component includes a second conductive element and a second sensor coil. The first conductive element and the second transmitting electrode are arranged at intervals on the rocker arm 200 and can move with the rocker arm 200. The first sensor coil and the second sensor coil are both installed and fixed on the housing 100 at corresponding intervals. When the rocker arm 200 moves, the overlapping area between the first conductive element and the first sensor coil changes to output a first electromagnetic signal of a corresponding magnitude; the overlapping area between the second conductive element and the second sensor coil also changes to output a second electromagnetic signal of a corresponding magnitude. At this time, the first sensing component and the second sensing component will output corresponding electromagnetic signals to the control component 50. In this way, the control component 500 processes the first electromagnetic signal and the second electromagnetic signal to obtain the action information of the joystick 200, which increases the output range of the sensing component 30 and further improves the sensitivity of the joystick device 100.

[0061] The present invention also proposes a game controller, which includes a joystick device 100. The specific structure of the joystick device 100 is as described in the above embodiments. Since the game controller adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0062] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
