[0031] As can be seen from the background technology, the accuracy of the joysticks in the relevant technologies is relatively low, which cannot meet users' increasingly higher demand for joystick accuracy.
[0032] To address the issue of low accuracy in related technologies, one embodiment of this application relates to a joystick device, comprising: a joystick, a rocker arm structure, a processor, and a circuit board; the rocker arm structure is disposed on the circuit board, and one end of the joystick is connected to the rocker arm structure; the rocker arm structure has multiple rotating shafts, and at least one rotating shaft extends a rotating portion along the direction close to the circuit board; multiple supports are disposed on a first surface of the circuit board near the rocker arm structure, and a groove is formed at the end of the support away from the circuit board, with the corresponding rotating shaft disposed in the groove; a conductor plate is disposed on the surface of the rotating portion near the circuit board, and at least one electrode plate support extends from the first surface of the circuit board, the electrode plate support being disposed opposite to the conductor plate, and a first electrode plate and a second electrode plate are disposed on the surface of the electrode plate support near the conductor plate; the processor is connected to the circuit board; when the rotating portion rotates with the joystick, the relative area of the conductor plate and the second electrode plate changes; the first electrode plate, the second electrode plate, and the conductor plate form a target capacitor; the processor is used to obtain the capacitance value of the target capacitor and determine the rotation direction and angle of the joystick based on the capacitance value.
[0033] This embodiment of the application forms a target capacitor by setting a conductor plate, a first electrode plate, and a second electrode plate in the rocker device. When the rocker rotates, the rocker drives the conductor plate to rotate through the rotating shaft, causing the relative area of the conductor plate and the second electrode plate to change. The capacitance value of the target capacitor formed by the conductor plate, the first electrode plate, and the second electrode plate changes. That is, the capacitance value of the target capacitor is different at different rotation angles. Thus, the rotation direction and angle of the rocker can be detected by the change in the capacitance value of the target capacitor. Compared with the Hall sensor method of related technologies, this embodiment realizes the angle measurement of the rocker device by capacitance detection. The rotation direction and angle of the rocker can be accurately determined by the change in the target capacitance, thereby improving the accuracy of the angle measurement of the rocker device.
[0034] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the various embodiments of this application will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this application to help readers better understand this application.

The division of the various embodiments below is for the convenience of description and should not constitute any limitation on the specific implementation of this application. The various embodiments can be combined with and referenced by each other without contradiction.
[0035] This application relates to a rocker arm device, such as... Figure 1 The diagram shown is a structural schematic of the rocker arm device in this embodiment. Figure 2 The diagram shown is a cross-sectional view of the rocker arm device in this embodiment. Figure 3 The diagram shown is an exploded view of the rocker arm device in this embodiment. Figure 4 The diagram shown is a partial schematic of the rocker arm device in this embodiment. Figure 5 The diagram shown is another partial schematic of the rocker arm device in this embodiment. Figure 6 The diagram shown is a partial schematic of the rocker arm device in this embodiment. Figure 7 The diagram shown is another partial schematic of the rocker arm device in this embodiment.
[0036] The joystick device in this embodiment includes: a joystick 10, a circuit board 20, a rocker arm structure 30, and a processor 40.
[0037] Specifically, the rocker arm structure 30 (including an upper rocker arm 301 and a lower rocker arm 302) is mounted on the circuit board 20, and one end of the rocker arm 10 is connected to the rocker arm structure 30. The rocker arm structure 30 has multiple rotating shafts 303, and at least one rotating shaft 303 extends a rotating part 304 in the direction close to the circuit board 20. Multiple supports 305 corresponding to the rotating part 304 are provided on the first surface of the circuit board 20 close to the rocker arm structure 30. The support 305 has a groove at the end away from the circuit board 20, and the corresponding rotating shaft 303 is disposed in the groove. A conductor plate 3041 is provided on the surface of the rotating part 304 close to the circuit board 20. At least one electrode plate support 200 extends on the first surface of the circuit board 20. The electrode plate support 200 is disposed opposite to the conductor plate 3041. A first electrode plate 2001 and a second electrode plate 2002 are provided on the surface of the electrode plate support 200 close to the conductor plate 3041.
[0038] The processor 40 is connected to the circuit board 20. When the conductor plate 3041 rotates with the rocker arm 10, the relative area of the conductor plate 3041 and the second electrode plate 2002 changes. The conductor plate 3041, the first electrode plate 2001, and the second electrode plate 2002 form a target capacitor. The circuit board 20 is also provided with multiple pins 201, so as to transmit the signal of the target capacitor received by the circuit board 20 to the processor 40. The processor 40 is used to obtain the capacitance value of the target capacitor and determine the rotation direction and angle of the rocker arm 10 based on the capacitance value.
[0039] The rocker arm structure 30 of this embodiment includes a lower rocker arm 302 and an upper rocker arm 301 covering the lower rocker arm 302. The upper rocker arm 301 rotates along a first axis following the rocker arm 10, and the lower rocker arm 302 rotates along a second axis following the rocker arm 10. The first axis and the second axis are perpendicular to each other. The upper rocker arm 301 has two rotating shafts 303 along the first axis, which are located on both sides of the upper rocker arm 301. The lower rocker arm 302 has two rotating shafts 303 along the second axis, which are located on both sides of the lower rocker arm 302. The upper rocker arm 301 is provided with a first... The lower rocker arm 302 has a second sliding opening, and the first sliding opening and the second sliding opening have the same orientation. The lower rocker arm 302 has two side walls that are symmetrical along the second axis and perpendicular to the first surface. Both side walls of the lower rocker arm 302 are provided with positioning holes 306. The end of the rocker arm 10 connected to the rocker arm structure 30 is provided with positioning elements 103 that match the positioning holes 306 one by one, specifically two positioning elements 103. The end of the rocker arm 10 connected to the rocker arm structure 30 passes through the first sliding opening and the second sliding opening in sequence so that the positioning elements 103 are assembled in the positioning holes 306.
[0040] Specifically, during rotation, the rocker arm 10 can rotate in the first sliding opening, causing the lower rocker arm 302 to rotate along the second axis, while the upper rocker arm 301 remains stationary. The rocker arm 10 can also rotate in the second sliding opening, causing the upper rocker arm 301 to rotate along the first axis, while the lower rocker arm 302 remains stationary. This method achieves the movement of the rocker arm 10. The rotating part 304 on the shaft 303 of the upper rocker arm 301, along with the corresponding conductor plate 3041, first electrode plate 2001, and second electrode plate 2002, is used to detect the rotation angle of the rocker arm 10 on the first axis. Similarly, the rotating part 304 on the shaft 303 of the lower rocker arm 302, along with the corresponding conductor plate 3041, first electrode plate 2001, and second electrode plate 2002, is used to detect the rotation angle of the rocker arm 10 on the second axis. This allows for the detection of the rotation angle of the rocker arm 10 in various directions, and the determination of the rotation direction and rotation angle of the rocker arm 10 in each direction based on these rotation angles.
[0041] Specifically, a base 50 is provided on the side of the circuit board 20 away from the rocker arm 10, that is, the circuit board 20 is placed on the base 50, and the base 50 provides support and protection for the circuit board 20, thereby improving the stability of the circuit board 20 during operation.
[0042] In some embodiments, reference Figure 3 , Figure 5The rotating part 304 is arc-shaped on the side near the electrode support 200, that is, the conductor plate 3041 is set on the arc-shaped surface, and the conductor plate 3041 has an arc-shaped structure; the electrode support 200 is provided with an arc-shaped groove on the side near the conductor plate 3041, and the first electrode plate 2001 and the second electrode plate 2002 are set in the arc-shaped groove, that is, the first electrode plate 2001 and the second electrode plate 2002 are also arc-shaped structures. In this embodiment, the centers of the arc-shaped conductor plate 3041, the first electrode plate 2001, and the second electrode plate 2002 are aligned and located on the rotating shaft 303 of the rocker arm structure 30. This arrangement ensures that the distance between the conductor plate 3041 and the first electrode plate 2001, and the distance between the conductor plate 3041 and the second electrode plate 2002 remain constant as the rotating part 304 rotates with the rocker arm 10. This makes the change in the target capacitance only related to the displacement of the conductor plate 3041, improving the accuracy of the target capacitance. By detecting the change in the target capacitance, the rotation angle of the rocker arm can be calculated, improving the accuracy of the angle measurement of the rocker arm device.
[0043] In this embodiment, the distance between the conductor plate 3041 and the first electrode plate 2001 and the second electrode plate 2002 is much smaller than the dimensions of the first electrode plate 2001 and the second electrode plate 2002. Since errors are inevitably introduced during actual manufacturing and assembly, if the distance between the conductor plate 3041 and the first electrode plate 2001 and the second electrode plate 2002 is large, especially the gap between them, it is easily affected by assembly tolerances, leading to drastic changes in the target capacitance. Therefore, this embodiment, by designing a smaller gap between the conductor plate 3041 and the first electrode plate 2001 and the second electrode plate 2002, and by setting both the conductor plate 3041, the first electrode plate 2001, and the second electrode plate 2002 as arc-shaped structures, can reduce or even eliminate the impact of gap errors, thereby improving detection accuracy.
[0044] Specifically, in this embodiment, the rocker arm 10 has a hollow region, within which a reset rod 101 connected to the circuit board 20 is disposed. The bottom of the reset rod 101 is connected to the circuit board 20, and a spring 102 is also sleeved on the reset rod 101. One end of the spring 102 abuts against the bottom of the reset rod 101 connected to the circuit board 20. A limiting member 104 is provided inside the hollow region of the rocker arm 10 to form a limiting groove, and the other end of the spring 102 abuts against the limiting groove. That is, the top of the spring 102 is disposed inside the limiting groove, realizing the elastic connection between the rocker arm 10 and the reset rod 101 through the spring 102. In this embodiment, by setting the reset rod 101, the rocker arm 10 can be reset. The reset rod 101 is also sleeved with the spring 102. By sleeved with the spring 102, the reset speed of the rocker arm 10 is improved, and the reset delay is minimized.
[0045] Specifically, the joystick device in this embodiment also includes a button 401, and a dome switch 402 is provided on the side of the button 401 near the circuit board 20; the first surface of the circuit board 20 is provided with a button area corresponding to and connected to the dome switch 402.
[0046] The button 401 has a U-shaped structure, with a groove on the side away from the circuit board 20. One of the pivots 303 of the rocker arm structure 30 is located in the groove of the U-shaped structure. When the rocker arm 10 is pressed, the rocker arm structure 30 presses the button 401 through the pivot 303. After the button 401 is pressed, it presses the dome switch 402. The dome switch 402 is equivalent to a switch, which triggers the button area in the circuit board 20, thereby triggering the corresponding function. In practical applications, when users play games with a gamepad equipped with a joystick 10, some scenarios require the use of button 401 for selection. For example, if a user needs to select a character using button 401, the user first moves the joystick 10 left or right to select a character from a row of characters, and then presses the joystick 10 down, which presses button 401. Button 401 then presses the dome switch 402, triggering the corresponding area of button 401 on the circuit board 20, thus selecting the character.
[0047] Continue to refer to Figure 5 , Figure 6 In this embodiment, two second electrode plates 2002 are provided on the electrode plate support 200; the two second electrode plates 2002 are arranged along the moving direction of the corresponding conductor plate 3041.
[0048] Specifically, when the rotating part 304 rotates with the rocker arm 10, the relative areas of the conductor plate 3041 and each second electrode plate 2002 change; the conductor plate 3041, the first electrode plate 2001 and each second electrode plate 2002 form a target capacitor; the processor 40 is used to obtain the capacitance values of multiple target capacitors and determine the rotation direction and angle of the rocker arm 10 based on the multiple capacitance values.
[0049] like Figure 8 The diagram shown is an equivalent schematic of the conductor plate, the first electrode plate, and the second electrode plate in this embodiment. The conductor plate 3041 moves from left to right. The relative area between the conductor plate 3041 and the first electrode plate 2001 remains unchanged. The relative area between the conductor plate 3041 and the left-side second electrode plate 2002 gradually decreases, while the relative area between the conductor plate 3041 and the right-side second electrode plate 2002 gradually increases. The target capacitance formed by the conductor plate 3041, the first electrode plate 2001, and the left-side second electrode plate 2002 is denoted as C1, and the target capacitance formed by the conductor plate 3041, the first electrode plate 2001, and the right-side second electrode plate 2002 is denoted as C2. Figure 9The figure shows a schematic diagram of the curves of the target capacitors C1 and C2. The horizontal axis represents the displacement of the conductor plate 3041, the vertical axis of the upper figure represents the value of the target capacitor C1, and the vertical axis of the lower figure represents the value of the target capacitor C2. It can be seen that as the conductor plate 3041 moves from left to right, C1 gradually decreases and C2 gradually increases. By detecting the changes in the capacitance values of the target capacitors C1 and C2, the rotation direction and angle of the rocker arm 10 can be detected, realizing the angle measurement of the rocker arm device. The rotation direction and angle of the rocker arm 10 can be accurately determined by the change in the target capacitance, thereby improving the accuracy of the angle measurement of the rocker arm device.
[0050] It should be noted that in this embodiment, the first electrode plate 2001 is a transmitting electrode plate and the second electrode plate 2002 is a receiving electrode plate; in other embodiments, the first electrode plate 2001 may also be a receiving electrode plate and the second electrode plate 2002 may also be a transmitting electrode plate.
[0051] In some embodiments, such as Figure 10 As shown, this is another equivalent schematic diagram of the conductor plate, first electrode plate, and second electrode plate in this embodiment. Two first electrode plates 2001 are disposed on the electrode plate support 200, and the two first electrode plates 2001 are respectively disposed on both sides of the two second electrode plates 2002. Figure 11 The diagram shows the principle between the conductor plate, the first electrode plate, and the second electrode plate in this embodiment. The electric field lines between the conductor plate 3041, the first electrode plate 2001, and the second electrode plate 2002 first pass through the first electrode plate 2001 to the conductor plate 3041, and then to the second electrode plate 2002, thereby enabling the first electrode plate 2001 and the second electrode plate 2002 to couple through the conductor plate 3041 to form the target capacitor.
[0052] In some embodiments, such as Figure 12 As shown, this is another equivalent schematic diagram of the conductor plate, first electrode plate, and second electrode plate in this embodiment. Four second electrode plates 2002 are disposed on the electrode plate support 200; two second electrode plates 2002 are disposed on the first side of the first electrode plate 2001 and arranged along the moving direction of the corresponding conductor plate 3041, and the other two second electrode plates 2002 are disposed on the second side of the first electrode plate 2001 and arranged along the moving direction of the corresponding conductor plate 3041; as shown... Figure 13 As shown, this is another schematic diagram of the principle between the conductor plate, the first electrode plate, and the second electrode plate in this embodiment. The electric field lines between the conductor plate 3041, the first electrode plate 2001, and the second electrode plate 2002 first pass through the first electrode plate 2001 to the conductor plate 3041, and then to the second electrode plate 2002, so that the first electrode plate 2001 and the second electrode plate 2002 are coupled through the conductor plate 3041 to form the target capacitor.
[0053] Specifically, when the rotating part 304 rotates with the rocker arm 10, the relative areas of the conductor plate 3041 and each second electrode plate 2002 change; the first electrode plate 2001, the conductor plate 3041 and each second electrode plate 2002 form a target capacitor; the processor 40 is used to obtain the capacitance values of multiple target capacitors and determine the rotation direction and angle of the rocker arm 10 based on the multiple capacitance values.
[0054] In one embodiment, two of the plurality of rotating shafts 303 are provided with rotating parts 304, and the two rotating shafts 303 rotate in different directions. (Continue to refer to...) Figure 1 , Figure 3 The rocker arm device has four rotating shafts 303. Two rotating shafts 303 are provided by the upper rocker arm 301, and the other two rotating shafts 303 are provided by the lower rocker arm 302. The four rotating shafts 303 are respectively arranged around the rocker arm structure 30. In this embodiment, one of the rotating shafts 303 of the upper rocker arm 301 is provided with a rotating part 304, and one of the rotating shafts 303 of the lower rocker arm 302 is provided with a rotating part 304. These two rotating parts 304 are arranged on two adjacent rotating shafts 303. That is to say, in this embodiment, a rotating part 304 is provided on one rotating shaft 303 of the upper rocker arm 301 to detect the rotation angle of the rocker arm 10 on the first axis, and a rotating part 304 is provided on one rotating shaft 303 of the lower rocker arm 302 to detect the rotation angle of the rocker arm 10 on the second axis. Thus, based on the rotation angle of the rocker arm 10 in each direction, not only the rotation direction of the rocker arm 10 can be determined, but also the rotation angle of the rocker arm 10 in the rotation direction can be determined.
[0055] Since this embodiment only sets up a capacitor structure formed by two sets of rotating parts 304 and electrode support 200, a button 401 can also be set at the rotating shaft 303 where no rotating part 304 is set, such as... Figure 1 , Figure 3 As shown, one pivot 303 of the lower rocker arm 302 is provided with a rotating part 304, and the other pivot 303 is provided in the groove of the "U" structure of the button 401; in other embodiments, the button 401 can be provided at one pivot 303 of the upper rocker arm 301, that is, one pivot 303 of the upper rocker arm 301 is provided with a rotating part 304, and the other pivot 303 is provided in the groove of the "U" structure of the button 401, thereby achieving the same function.
[0056] In other embodiments, for multiple rotating shafts 303, one rotating shaft 303 may be set in the groove of the "U" structure of the button 401, and the other rotating shafts 303 may be provided with corresponding brackets 305; for example, the rocker arm structure 30 may have four rotating shafts 303, one rotating shaft 303 may be set in the groove of the "U" structure of the button 401, and the other three rotating shafts 303 may each be provided with a rotating part 304, and the inner side of the corresponding three brackets 305 may be provided with an electrode plate bracket 200; or, of the other three rotating shafts 303, two rotating shafts 303 may be provided with a rotating part 304, the inner side of the corresponding two brackets 305 may be provided with an electrode plate bracket 200, and the remaining rotating shaft 303 may not be provided with a rotating part 304, and the inner side of the corresponding bracket 305 may not be provided with an electrode plate bracket 200.
[0057] In one embodiment, each of the plurality of rotating shafts 303 has a rotating portion 304 disposed in a direction close to the circuit board 20. For example... Figure 1 , Figure 3 As shown, the rocker arm device has four rotating shafts 303. Two rotating shafts 303 are provided by the upper rocker arm 301, and the other two rotating shafts 303 are provided by the lower rocker arm 302. The four rotating shafts 303 are respectively arranged around the rocker arm structure 30. In this embodiment, each rotating shaft 303 is provided with a rotating part 304. Correspondingly, the circuit board 20 is provided with four corresponding electrode plate supports 200. That is to say, in this embodiment, the two rotating shafts 303 of the upper rocker arm 301 are provided with rotating parts 304 to detect the rotation angle of the rocker arm 10 on the first axis, and the two rotating shafts 303 of the lower rocker arm 302 are provided with rotating parts 304 to detect the rotation angle of the rocker arm 10 on the second axis. Thus, based on the rotation angle of the rocker arm 10 in each direction, not only the rotation direction of the rocker arm 10 can be determined, but also the rotation angle of the rocker arm 10 in the rotation direction can be determined, further improving the accuracy of the angle measurement of the rocker arm 10.
[0058] In this embodiment, the first electrode plate 2001 and the second electrode plate 2002 can be electrically connected to the processor 40, i.e., the chip, via the circuit board 20. (Refer to...) Figure 6 The circuit board 20 is provided with leads 60 connecting the processor 40 to the first electrode 2001 and the second electrode 2002. The leads 60 can be formed using laser direct forming (LDS) technology. LDS uses a computer to control the movement of the laser according to the trajectory of the conductive pattern, and projects the laser onto the molded three-dimensional plastic device to activate the circuit pattern in a very short time. That is, on the molded plastic support such as the circuit board 20, a metal pattern is directly formed on the circuit board 20 by laser plating technology.
[0059] The conductor plate 3041, the first electrode plate 2001, and the second electrode plate 2002 in this embodiment can also be formed using LDS technology. For example, for the upper rocker arm 301 and the lower rocker arm 302, after their main body is manufactured by injection molding of the corresponding polymer material, a conductive coating is electroplated on a specific area, such as the rotating part 304, using LDS technology, thus forming the conductor plate 3041 on the rotating part 304. For the circuit board 20, after its main body is manufactured by injection molding of the polymer material, a conductive coating is electroplated on a specific area, such as the groove of the electrode plate support 200, using LDS technology, thus forming the first electrode plate 2001 and the second electrode plate 2002 in the groove of the electrode plate support 200. After the first electrode plate 2001 and the second electrode plate 2002 are electroplated using LDS technology, the leads 60 can be further electroplated using the LDS process to connect the first electrode plate 2001 and the second electrode plate 2002 to the corresponding pins of the processor 40. In addition, some pins of the processor 40 also need to be plated with additional leads using the LDS process to connect to the dome switch 402 or other communication terminals.
[0060] In this embodiment, the conductive structures such as leads 60 and electrode plates required by the solution are engraved onto the circuit board 20 using the LDS process. The circuit board 20 and rocker arm structure 30 are formed in one step by plastic injection molding, which minimizes the number of parts and saves costs while further improving the fitting accuracy.
[0061] This embodiment of the application forms a target capacitor by setting a conductor plate 3041, a first electrode plate 2001, and a second electrode plate 2002 in the rocker device. When the rocker 10 rotates, the rocker 10 drives the conductor plate 3041 to rotate through the rotating shaft, causing the relative area of the conductor plate 3041 and the second electrode plate 2002 to change. The capacitance value of the target capacitor formed by the conductor plate 3041, the first electrode plate 2001, and the second electrode plate 2002 changes. That is, the capacitance value of the target capacitor is different at different rotation angles. Thus, the rotation direction and angle of the rocker 10 can be detected by the change in the capacitance value of the target capacitor. Compared with the Hall sensor method of related technologies, this embodiment realizes the angle measurement of the rocker device through capacitance detection. The rotation direction and angle of the rocker 10 can be accurately determined by the change in the target capacitance, improving the accuracy of the angle measurement of the rocker device. At the same time, this embodiment does not require additional sensors, saving the volume of the rocker device and making it more conducive to the miniaturization design of the rocker device.
