Description

Technical Field

[0001] This application relates to the field of remote control technology, and more specifically, to a capacitive joystick device and a handheld remote control. Background Technology

[0002] Joysticks are common components in various remote control devices, and their swing position needs to be detected during use. Carbon film joystick technology is currently the mainstream approach. Its principle involves a brush sliding across a carbon film to change the resistance value, thereby generating a joystick signal. Carbon film joysticks can provide high-precision control through their contact structure. However, due to the mechanical contact, prolonged use or heavy use will increase wear on both the brush and the carbon film, affecting the accuracy of the joystick's swing position detection. Furthermore, if foreign objects are present between the brush and the carbon film, it can lead to unstable contact, causing abnormal joystick signal output, which will also affect the detection accuracy. Utility Model Content

[0003] In view of this, this application provides a capacitive joystick device and a handle remote control to solve the technical problem of low detection accuracy caused by mechanical wear and foreign object interference in contact joysticks.

[0004] One embodiment of this application provides a capacitor rocker device. The capacitor rocker device includes a circuit board, a detection component, and a rocker assembly. The detection component includes a first moving electrode, a second moving electrode, and a stationary electrode. The first moving electrode, the second moving electrode, and the stationary electrode are electrically connected to the circuit board. The first moving electrode and the stationary electrode are spaced apart along the thickness direction of the circuit board to form a first capacitor. The second moving electrode and the stationary electrode are spaced apart along the thickness direction of the circuit board to form a second capacitor. The rocker assembly and the detection component are connected. The rocker assembly is used to swing to simultaneously move the first moving electrode and the second moving electrode relative to the stationary electrode in a plane perpendicular to the thickness direction of the circuit board. When the rocker assembly swings, it can change the relative area between the first moving electrode and the stationary electrode, and the relative area between the second moving electrode and the stationary electrode, thereby changing the capacitance value of the first capacitor and the capacitance value of the second capacitor.

[0005] Manipulating the joystick assembly causes the first and second moving electrodes to move relative to the stationary electrode, thereby changing the relative areas between the first and second moving electrodes and the stationary electrode. The capacitance of the first capacitor is related to the relative area between the first and second moving electrodes, and the capacitance of the second capacitor is related to the relative area between the second moving electrodes and the stationary electrode. Therefore, the position of the joystick assembly can be determined by the changes in the capacitance values ​​of the first and second capacitors. There is no physical contact between the first and second moving electrodes, or between the first and second moving electrodes; detection is achieved through capacitive sensing. This provides high-precision position detection, avoids mechanical wear and fatigue problems, extends the service life of the capacitive joystick device, and is less susceptible to interference from foreign objects, effectively ensuring detection accuracy.

[0006] In some embodiments, the stationary electrode has an extending direction. A first moving electrode and a second moving electrode are spaced apart along the extending direction. The extending direction intersects the thickness direction of the circuit board. Along the thickness direction of the circuit board, the projections of the first moving electrode and the stationary electrode at least partially overlap, and the overlapping portion is a first portion. Along the thickness direction of the circuit board, the projections of the second moving electrode and the stationary electrode at least partially overlap, and the overlapping portion is a second portion. A rocker assembly oscillates, causing the first and second moving electrodes to move simultaneously relative to the stationary electrode along the extending direction, thereby increasing the area of ​​the first portion and decreasing the area of ​​the second portion, or decreasing the area of ​​the first portion and increasing the area of ​​the second portion.

[0007] When the joystick assembly is in its initial position, the areas of the first and second parts are equal, and the capacitance of the first capacitor is equal to the capacitance of the second capacitor. When the joystick assembly swings, if the area of ​​the first part increases and the area of ​​the second part decreases, then the capacitance of the first capacitor is greater than the capacitance of the second capacitor. Therefore, it can be determined that the first and second moving electrodes move in the direction from the first moving electrode to the second moving electrode. The position of the joystick assembly can also be determined based on the numerical relationship between the capacitance values ​​of the first and second capacitors. Conversely, if the area of ​​the first part decreases and the area of ​​the second part increases when the joystick assembly swings, then the capacitance of the first capacitor is less than the capacitance of the second capacitor. Therefore, it can be determined that the first and second moving electrodes move in the direction from the second moving electrode to the first moving electrode. The position of the joystick assembly can also be determined based on the numerical relationship between the capacitance values ​​of the first and second capacitors.

[0008] In some embodiments, both the first moving electrode and the second moving electrode include an electrode body and an elastic member. The electrode body and the stationary electrode of the first moving electrode are spaced apart along the thickness direction of the circuit board. The electrode body and the stationary electrode of the second moving electrode are also spaced apart along the thickness direction of the circuit board. The elastic member includes a connecting portion and an arcuate contact portion. The connecting portion is connected to the electrode body. The arcuate contact portion is configured to protrude towards the circuit board. The arcuate contact portion and the circuit board make elastic contact to achieve electrical connection.

[0009] When the elastic element comes into contact with the circuit board, it undergoes elastic deformation. This deformation provides stable, continuous, and adaptive contact pressure, improving the reliability of the electrical connection between the first moving electrode, the second moving electrode, and the circuit board. Furthermore, the arc-shaped contact portion protrudes towards the circuit board, allowing for arc-surface contact between the elastic element and the circuit board. This reduces wear on the circuit board from the elastic element, extending the service life of both the circuit board and the elastic element.

[0010] In some embodiments, the stationary electrode has an extending direction. When the rocker assembly swings, it simultaneously drives the first and second moving electrodes to move relative to the stationary electrode along the extending direction. There are two elastic elements, spaced apart in a direction perpendicular to both the extending direction and the thickness direction of the circuit board.

[0011] The arc-shaped contact portion of the elastic element serves as the contact terminal between the electrode body and the circuit board. If only one elastic element is provided, there are only two contact terminals between the detection component and the circuit board. When the rocker assembly swings, since the rocker assembly does not translate along the extension direction, the swing path of the rocker assembly is an arc. Taking the rocker assembly swinging towards the side where the second moving electrode is located as an example, the arc-shaped contact portion of the second moving electrode will be subjected to force and abut against the circuit board, while the arc-shaped contact portion of the first moving electrode may be raised, affecting the electrical connection between the first moving electrode and the circuit board. By providing two elastic elements in a direction perpendicular to the extension direction and perpendicular to the thickness direction of the circuit board, taking the rocker assembly swinging towards the side where the second moving electrode is located as an example again, the first moving electrode and the circuit board are electrically connected through two arc-shaped contact portions. Even if one arc-shaped contact portion is raised, the other arc-shaped contact portion can still maintain a reliable electrical connection, thereby improving the stability and reliability of the electrical connection between the first and second moving electrodes and the circuit board.

[0012] In some embodiments, the number of detection components is two sets. One set of detection components is located on one side of the rocker assembly along a first direction. The other set of detection components is located on one side of the rocker assembly along a second direction. The first direction, the second direction, and the thickness direction of the circuit board intersect each other.

[0013] One set of detection components can determine the position of the joystick assembly in a first direction, and another set of detection components can determine the position of the joystick assembly in a second direction, thereby determining the position of the joystick assembly on a plane perpendicular to the thickness direction of the circuit board.

[0014] In some embodiments, the capacitive rocker device further includes a capacitor chip. The capacitor chip is disposed on and electrically connected to a circuit board. A first moving electrode, a second moving electrode, and a stationary electrode are electrically connected to the capacitor chip. The capacitor chip is used to acquire the capacitance values ​​of the first capacitor and the second capacitor and output a sensing signal.

[0015] In some embodiments, the detection assembly further includes a connector. The connector includes an assembly portion, a first mounting portion, and a second mounting portion. The assembly portion is connected to the rocker assembly. The first mounting portion is fixedly connected to the first moving electrode. The second mounting portion is fixedly connected to the second moving electrode.

[0016] In some embodiments, both the first mounting portion and the second mounting portion are provided with stop grooves. Both the first moving electrode and the second moving electrode include an electrode body and a fixing portion connected to the electrode body. The fixing portion of the first moving electrode is fitted into the stop groove of the first mounting portion to fix the first moving electrode and the connector. The fixing portion of the second moving electrode is fitted into the stop groove of the second mounting portion to fix the second moving electrode and the connector.

[0017] In some embodiments, the rocker assembly includes a rocker body, a toggle member, and a oscillating member disposed on the toggle member. The toggle member is movably connected to the rocker. The rocker body pushes the toggle member to oscillate. The oscillating member has a mounting groove along the thickness direction of the circuit board. A mounting portion is disposed within the mounting groove. The sidewall of the mounting groove stops the mounting portion from moving relative to the oscillating member in a plane perpendicular to the thickness direction of the circuit board.

[0018] One embodiment of this application provides a handheld remote control. The handheld remote control includes a capacitive joystick device as described in any of the above embodiments. Attached Figure Description

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0034] The definitions of "first direction", "second direction" and "third direction" are for the purpose of describing the relative positional relationship of related structures, and do not mean that "first direction", "second direction" and "third direction" need to depend on the related structures involved in the above definitions.

[0035] In the description of this application, it should be noted that the terms "left", "right", "vertical", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0036] Furthermore, the terms “first,” “second,” “third,” etc., are used for descriptive purposes only and should not be interpreted as indicating or implying relative importance.

[0037] The term "perpendicular" is used to describe an ideal state between two components. In actual production or use, two components can exist in a state that is approximately perpendicular. The two components described as "perpendicular" do not have to be absolute straight lines or planes, but can be roughly straight lines or planes. From a macroscopic perspective, if the overall direction of extension is a straight line or plane, the component can be considered a "straight line" or "plane".

[0038] The term "parallel" is used to describe an ideal state between two components. In actual production or use, two components can exist in a state that is approximately parallel.

[0039] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intervening component present.

[0040] The term “and / or” as used herein includes any and all combinations of one or more of the related listed items.

[0041] This application provides a capacitor rocker device. The capacitor rocker device includes a circuit board, a detection component, and a rocker assembly. The detection component includes a first moving electrode, a second moving electrode, and a stationary electrode. The first moving electrode, the second moving electrode, and the stationary electrode are electrically connected to the circuit board. The first moving electrode and the stationary electrode are spaced apart along the thickness direction of the circuit board to form a first capacitor. The second moving electrode and the stationary electrode are spaced apart along the thickness direction of the circuit board to form a second capacitor. The rocker assembly and the detection component are connected. The rocker assembly is used to swing to simultaneously move the first moving electrode and the second moving electrode relative to the stationary electrode in a plane perpendicular to the thickness direction of the circuit board. When the rocker assembly swings, it can change the relative area between the first moving electrode and the stationary electrode, and the relative area between the second moving electrode and the stationary electrode, thereby changing the capacitance value of the first capacitor and the capacitance value of the second capacitor.

[0042] Manipulating the joystick assembly causes the first and second moving electrodes to move relative to the stationary electrode, thereby changing the relative areas between the first and second moving electrodes and the stationary electrode. The capacitance of the first capacitor is related to the relative area between the first and second moving electrodes, and the capacitance of the second capacitor is related to the relative area between the second moving electrodes and the stationary electrode. Therefore, the position of the joystick assembly can be determined by the changes in the capacitance values ​​of the first and second capacitors. There is no physical contact between the first and second moving electrodes, or between the first and second moving electrodes; detection is achieved through capacitive sensing. This provides high-precision position detection, avoids mechanical wear and fatigue problems, extends the service life of the capacitive joystick device, and is less susceptible to interference from foreign objects, effectively ensuring detection accuracy.

[0043] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0044] Please see Figure 1 and Figure 2 One embodiment of this application provides a capacitor rocker device 100. The capacitor rocker device 100 includes a circuit board 1, a detection component 2, and a rocker assembly 3. The detection component 2 includes a first moving electrode 21, a second moving electrode 22, and a stationary electrode 23. The first moving electrode 21, the second moving electrode 22, and the stationary electrode 23 are electrically connected to the circuit board 1. The first moving electrode 21 and the stationary electrode 23 are spaced apart along the thickness direction of the circuit board 1 to form a first capacitor. The second moving electrode 22 and the stationary electrode 23 are spaced apart along the thickness direction of the circuit board 1 to form a second capacitor. The rocker assembly 3 is connected to the detection component 2. The rocker assembly 3 is used to swing to simultaneously move the first moving electrode 21 and the second moving electrode 22 relative to the stationary electrode 23 in a plane perpendicular to the thickness direction of the circuit board 1. When the rocker assembly 3 swings, it can change the relative area between the first moving electrode 21 and the stationary electrode 23, and the relative area between the second moving electrode 22 and the stationary electrode 23, thereby changing the capacitance value of the first capacitor and the capacitance value of the second capacitor.

[0045] Manipulating the joystick assembly 3 causes the first moving electrode 21 and the second moving electrode 22 to move relative to the stationary electrode 23, thereby changing the relative areas between the first moving electrode 21 and the stationary electrode 23, and between the second moving electrode 22 and the stationary electrode 23. The capacitance value of the first capacitor is related to the relative area between the first moving electrode 21 and the stationary electrode 23, and the capacitance value of the second capacitor is related to the relative area between the second moving electrode 22 and the stationary electrode 23. Therefore, the position of the joystick assembly 3 can be determined by the changes in the capacitance values ​​of the first and second capacitors. There is no physical contact between the first moving electrode 21 and the stationary electrode 23, or between the second moving electrode 22 and the stationary electrode 23; detection is performed through capacitive sensing. This provides high-precision position detection, avoids mechanical wear and fatigue problems, improves the service life of the capacitive joystick device 100, and is less susceptible to interference from foreign objects, effectively ensuring detection accuracy.

[0046] In some embodiments, the capacitive joystick device 100 serves as an input device, typically used in drone control handles, game controllers, etc. Figure 1 and Figure 2 As shown, the capacitive rocker assembly 100 includes a housing 6, a circuit board 1, a detection component 2, and a rocker assembly 3. The housing 6 typically includes a base 61 and a top cover 62. The circuit board 1 is disposed on the base 61, and the base 61 and the top cover 62 are fastened together to form a mounting cavity 60 for mounting the circuit board 1, the detection component 2, and the rocker assembly 3 (see [reference]). Figure 9 ).

[0047] Please see Figure 3 In some embodiments, a stationary electrode 23 is disposed on a circuit board 1. The stationary electrode 23 has an extending direction. A first moving electrode 21 and a second moving electrode 22 are spaced apart along the extending direction and located on the same side of the stationary electrode 23. The extending direction of the stationary electrode 23 intersects the thickness direction of the circuit board 1. Along the thickness direction of the circuit board 1, the projections of the first moving electrode 21 and the stationary electrode 23 at least partially overlap, and the overlapping portion is a first portion 201. Along the thickness direction of the circuit board 1, the projections of the second moving electrode 22 and the stationary electrode 23 at least partially overlap, and the overlapping portion is a second portion 202. The rocker assembly 3 swings, causing the first moving electrode 21 and the second moving electrode 22 to move simultaneously relative to the stationary electrode 23 along the extending direction, thereby increasing the area of ​​the first portion 201 and decreasing the area of ​​the second portion 202, or decreasing the area of ​​the first portion 201 and increasing the area of ​​the second portion 202.

[0048] When the joystick assembly 3 is in its initial position, the areas of the first part 201 and the second part 202 are equal, and the capacitance of the first capacitor is equal to the capacitance of the second capacitor. When the joystick assembly 3 swings, if the area of ​​the first part 201 increases and the area of ​​the second part 202 decreases, then the capacitance of the first capacitor is greater than the capacitance of the second capacitor. Therefore, it can be determined that the first moving electrode 21 and the second moving electrode 22 move along the direction from the first moving electrode 21 to the second moving electrode 22. The position of the joystick assembly 3 can also be determined based on the numerical relationship between the capacitance values ​​of the first and second capacitors. Conversely, when the joystick assembly 3 swings, if the area of ​​the first part 201 decreases and the area of ​​the second part 202 increases, then the capacitance of the first capacitor is less than the capacitance of the second capacitor. Therefore, it can be determined that the first moving electrode 21 and the second moving electrode 22 move along the direction from the second moving electrode 22 to the first moving electrode 21. The position of the joystick assembly 3 can also be determined based on the numerical relationship between the capacitance values ​​of the first and second capacitors.

[0049] Understandably, in Figure 3 In the diagram, the first part 201 represents the overlapping portion of the projection of the first moving electrode 21 and the projection of the stationary electrode 23 in the thickness direction of the circuit board 1; the second part 202 represents the overlapping portion of the projection of the second moving electrode 22 and the projection of the stationary electrode 23 in the thickness direction of the circuit board 1; it is not a part of the stationary electrode 23.

[0050] Please see Figure 3 and Figure 4 In some embodiments, both the first moving electrode 21 and the second moving electrode 22 include an electrode body 210 and an elastic member 220. The electrode body 210 of the first moving electrode 21 and the stationary electrode 23 are spaced apart along the thickness direction of the circuit board 1. The electrode body 210 of the second moving electrode 22 and the stationary electrode 23 are also spaced apart along the thickness direction of the circuit board 1. The elastic member 220 includes a connecting portion 2201 and an arc-shaped contact portion 2202. The connecting portion 2201 is connected to the electrode body 210. The arc-shaped contact portion 2202 is configured to protrude towards the circuit board 1. The arc-shaped contact portion 2202 and the circuit board 1 make elastic contact to achieve electrical connection.

[0051] When the elastic element 220 comes into contact with the circuit board 1, it undergoes elastic deformation. This elastic deformation provides stable, continuous, and adaptive contact pressure, improving the reliability of the electrical connection between the first moving electrode 21, the second moving electrode 22, and the circuit board 1. Furthermore, the arc-shaped contact portion 2202 protrudes towards the circuit board 1, allowing the elastic element 220 and the circuit board 1 to make contact via an arc surface. This reduces wear on the circuit board 1 caused by the elastic element 220, extending the service life of both the circuit board 1 and the elastic element 220.

[0052] In some embodiments, the electrode body 210 and the elastic element 220 are integrally formed.

[0053] In some embodiments, the elastic element 220 and the circuit board 1 are electrically connected by a metal conductive element.

[0054] In some embodiments, the stationary electrode 23 has an extending direction. When the rocker assembly 3 swings, it simultaneously drives the first moving electrode 21 and the second moving electrode 22 to move relative to the stationary electrode 23 along the extending direction. There are two elastic members 220, which are spaced apart in a direction perpendicular to the extending direction and perpendicular to the thickness direction of the circuit board 1.

[0055] The arc-shaped contact portion 2202 of the elastic element 220 serves as a contact terminal between the electrode body 210 and the circuit board 1. If only one elastic element 220 is provided, there are only two contact terminals between the detection component 2 and the circuit board 1. When the rocker assembly 3 swings, since the rocker assembly 3 does not translate along the extension direction, the swing path of the rocker assembly 3 is an arc. Taking the rocker assembly 3 swinging towards the side where the second moving electrode 22 is located as an example, the arc-shaped contact portion 2202 of the second moving electrode 22 will be subjected to force and abut against the circuit board 1, while the arc-shaped contact portion 2202 of the first moving electrode 21 may be lifted up, affecting the electrical connection between the first moving electrode 21 and the circuit board 1. Two elastic members 220 are provided in a direction perpendicular to the extension direction and the thickness direction of the circuit board 1. Taking the rocker assembly 3 swinging toward the side where the second moving electrode 22 is located as an example, the first moving electrode 21 and the circuit board 1 are electrically connected through two arc-shaped contact parts 2202. One arc-shaped contact part 2202 is raised, while the other arc-shaped contact part 2202 can still maintain a reliable electrical connection, thereby improving the stability and reliability of the electrical connection between the first moving electrode 21 and the second moving electrode 22 and the circuit board 1.

[0056] Please see Figure 5 In some embodiments, the number of detection components 2 is two sets. One set of detection components 2 is located on one side of the rocker assembly 3 along the first direction X. The other set of detection components 2 is located on one side of the rocker assembly 3 along the second direction Y. The first direction X, the second direction Y, and the thickness direction of the circuit board 1 intersect each other. Figure 5 In the example shown, the thickness direction of circuit board 1 is the third direction Z.

[0057] One set of detection components 2 can determine the position of the joystick assembly 3 in the first direction X, and another set of detection components 2 can determine the position of the joystick assembly 3 in the second direction Y, thereby determining the position of the joystick assembly 3 on a plane perpendicular to the thickness direction of the circuit board 1.

[0058] Please continue reading Figure 5 ,by Figure 5Taking the direction shown as an example, one set of detection components 2 is the first detection component 20a, and the other set of detection components 2 is the second detection component 20b. In the first detection component 20a, its stationary electrode 23 extends along the first direction X, so the first detection component 20a can determine the position of the rocker arm assembly 3 in the first direction X. In the second detection component 20b, its stationary electrode 23 extends along the second direction Y, so the second detection component 20b can determine the position of the rocker arm assembly 3 in the second direction Y.

[0059] Please see Figure 2 In some embodiments, the capacitive rocker device 100 further includes a capacitor chip 4. The capacitor chip 4 is disposed on and electrically connected to the circuit board 1. The first moving electrode 21, the second moving electrode 22, and the stationary electrode 23 are electrically connected to the capacitor chip 4, respectively. The capacitor chip 4 is used to acquire the capacitance value of the first capacitor and the capacitance value of the second capacitor and output a sensing signal.

[0060] Regarding the capacitor chip 4, it can realize signal detection and control functions through the principle of capacitance. The working principle of the capacitor chip 4 is to utilize the charge storage characteristics between two conductors, and convert physical signals into digital signals by sensing changes in capacitance caused by changes in the surrounding environment (such as objects approaching, pressure sensing, etc.). In various embodiments of this application, the capacitor chip 4 is used to detect the capacitance values ​​of the first capacitor and the second capacitor. By detecting the change in the ratio of the capacitance values ​​of the first capacitor and the second capacitor, the embodiments of this application determine the position information input by the user through the joystick assembly 3, thus avoiding the influence of environmental factors (temperature, etc.) on the capacitance value. The capacitor chip 4 has high sensitivity, can detect minute capacitance changes, and is less affected by electromagnetic interference, which helps to improve the control accuracy of the capacitor joystick device 100.

[0061] The sensing signal output by capacitor chip 4 specifically refers to the position information of the joystick assembly 3 on a plane perpendicular to the thickness direction of circuit board 1. Taking a game controller as an example, the position information refers to the position information output by the player through the swing of the joystick assembly 3, or the command information that can be used to interact with the game software.

[0062] Please see Figure 6 In some embodiments, the detection component 2 further includes a connector 24. The connector 24 includes an assembly portion 243, a first mounting portion 241, and a second mounting portion 242. The assembly portion 243 is connected to the rocker assembly 3. The first mounting portion 241 is fixedly connected to the first moving electrode 21. The second mounting portion 242 is fixedly connected to the second moving electrode 22.

[0063] In this way, when the rocker assembly 3 swings, the first moving electrode 21 and the second moving electrode 22 can be driven to move in the same direction through the connector 24, so that the area of ​​the first part 201 increases and the area of ​​the second part 202 decreases, or the area of ​​the first part 201 decreases and the area of ​​the second part 202 increases.

[0064] In some embodiments, both the first mounting portion 241 and the second mounting portion 242 are provided with a stop groove 240. Both the first movable electrode 21 and the second movable electrode 22 include an electrode body 210 and a fixing portion 211 connected to the electrode body 210. The fixing portion 211 of the first movable electrode 21 is fitted into the stop groove 240 of the first mounting portion 241 to fix the first movable electrode 21 and the connector 24. The fixing portion 211 of the second movable electrode 22 is fitted into the stop groove 240 of the second mounting portion 242 to fix the second movable electrode 22 and the connector 24.

[0065] Please see Figures 5 to 7 In some embodiments, the rocker assembly 3 includes a rocker body 31, a toggle member 32, and a swing member 33 disposed on the toggle member 32. The toggle member 32 is movably connected to the rocker. The rocker pushes the toggle member 32 to swing. The swing member 33 has a mounting groove 330 along the thickness direction of the circuit board 1. A mounting part 243 is disposed in the mounting groove 330. The side wall of the mounting groove 330 stops the mounting part 243 to move relative to the swing member 33 in a plane perpendicular to the thickness direction of the circuit board 1.

[0066] Please see Figure 5 and Figure 7 In some embodiments, there are two actuating elements 32, each actuating element 32 having at least one oscillating element 33. One actuating element 32 is a first actuating element 321, and the other actuating element 32 is a second actuating element 322. There are two sets of detection components 2. One set of detection components 2 is a first detection component 20a, and the other set of detection components 2 is a second detection component 20b. Figure 5 Taking the illustrated embodiment as an example, the stationary electrode 23 of the first detection component 20a extends along the first direction X, and the oscillating member 33 of the first actuating member 321 is disposed on one side of the first actuating member 321 along the second direction Y and is connected to the connecting member 24 of the first detection component 20a. The stationary electrode 23 of the second detection component 20b extends along the second direction Y, and the oscillating member 33 of the second actuating member 322 is disposed on one side of the second actuating member 322 along the first direction X and is connected to the connecting member 24 of the second detection component 20b.

[0067] Continue with Figure 5Taking the direction of movement as an example, when the rocker body 31 swings along the first direction X towards the side where the second moving electrode 22 of the first detection component 20a is located, the swinging member 33 of the first actuating member 321 will drive the connecting member 24 to move along the direction from the second moving electrode 22 to the first moving electrode 21. For the first detection component 20a, the relative area between the first moving electrode 21 and the stationary electrode 23 will decrease, and the relative area between the second moving electrode 22 and the stationary electrode 23 will increase. As a result, the capacitance values ​​of the first capacitor and the second capacitor of the first detection component 20a will change. The reverse is also true.

[0068] When the rocker arm 31 swings along the second direction Y toward the side where the second moving electrode 22 of the second detection component 20b is located, the swinging member 33 of the second actuating member 322 will drive the connecting member 24 to move along the direction from the second moving electrode 22 to the first moving electrode 21. For the second detection component 20b, the relative area between the first moving electrode 21 and the stationary electrode 23 will decrease, and the relative area between the second moving electrode 22 and the stationary electrode 23 will increase. As a result, the capacitance values ​​of the first capacitor and the second capacitor of the second detection component 20b will change. The reverse is also true.

[0069] In this way, the capacitor chip 4 can determine the position of the joystick assembly 3 based on the change in the capacitance value.

[0070] Please see Figure 8 In some embodiments, the capacitive rocker assembly 100 further includes a switch spring 5. The switch spring 5 is disposed on the circuit board 1 and configured to be elastically deformable for electrical connection with the circuit board 1. There are two oscillating elements 33. One oscillating element 33 is connected to the connector 24 of the detection assembly 2, and the other oscillating element 33 is used to abut against the switch spring 5. When the rocker assembly 3 moves along the thickness direction of the circuit board 1, the rocker body 31 drives the actuating element 32 to move along the thickness direction of the circuit board 1, causing the oscillating element 33 to move closer to or further away from the switch spring 5.

[0071] Taking a game controller as an example, the player presses the joystick body 31, causing the joystick body 31 to move the toggle member 32 along the thickness direction of the circuit board 1. The swing member 33 located above the switch spring 5 moves toward the switch spring 5 and contacts the switch spring 5. The switch spring 5 is subjected to pressure from the swing member 33, causing it to elastically deform and contact the circuit board 1, thus establishing an electrical connection with the circuit board 1. This allows the capacitive joystick device 100 to output commands such as "confirm" or "pick up". It should be noted that the location above the switch spring 5 is only an example in the illustrated direction, and this embodiment does not impose any limitations on this.

[0072] In some embodiments, the mounting groove 330 extends along the thickness direction of the circuit board 1. When the actuating member 32 moves along the thickness direction of the circuit board 1, the mounting portion 243 of the connector 24 does not restrict the movement of the actuating member 32.

[0073] Please see Figure 9 In some embodiments, the rocker assembly 3 further includes a reset member 34, which is compressed between the toggle member 32 and the base 61. The reset member 34 assists the rocker assembly 3 in returning to its center after swinging. Preferably, the reset member 34 includes, but is not limited to, a spring.
