[0034] The bracket 201 of this embodiment has a groove at one end away from the circuit board, and the corresponding rotating shaft is arranged in the groove; thereby, the bracket 201 can also support the rotating shaft, thereby improving the stability of the rocker arm structure.

[0035] The rocker arm structure of this embodiment includes a lower rocker arm 402 and an upper rocker arm 401 covered on the lower rocker arm 402. The upper rocker arm 401 rotates along the first axis following the rocker arm 10, and the lower rocker arm 402 rotates along the second axis following the rocker arm 10. The first axis and the second axis are arranged perpendicularly; the upper rocker arm 401 is provided with two rotating shafts 403 along the first axis direction, and the lower rocker arm 402 is provided with two rotating shafts 403 along the second axis direction; a first sliding opening 405 is provided on the side of the upper rocker arm 401 close to the upper cover 30, and a second sliding opening 406 is provided on the side of the lower rocker arm 402 close to the upper cover 30; positioning holes 407 are provided on both side walls of the lower rocker arm 402 perpendicular to the first surface, and a positioning piece 103 that matches the positioning hole 407 is provided on one end of the rocker arm 10 connected to the rocker arm structure; the rocker arm 10 passes through the first sliding opening 405 and the second sliding opening 406 in sequence so that the positioning piece 103 is assembled in the positioning hole 407.

[0036] Specifically, during the rotation of the rocker arm 10, the rocker arm 10 can rotate in the first sliding opening 405 and drive the lower rocker arm 402 to rotate along the second axis with the rocker arm 10, while the upper rocker arm 401 does not rotate; the rocker arm 10 can also rotate in the second sliding opening 406 and drive the upper rocker arm 401 to rotate along the first axis with the rocker arm 10, while the lower rocker arm 402 does not rotate; in this way, the movement of the rocker arm 10 is achieved, and the first electrode plate 2021 and the second electrode plate 2022 corresponding to the first rotating portion 404 provided on the rotating shaft 403 of the upper rocker arm 401 are used to detect the rotation angle of the rocker arm 10 on the first axis, and the first electrode plate 2021 and the second electrode plate 2022 corresponding to the first rotating portion 404 provided on the rotating shaft 403 of the lower rocker arm 402 are used to detect the rotation angle of the rocker arm 10 on the second axis, thereby realizing the detection of the rotation angle of the rocker arm 10 in various directions, and then determining the rotation direction of the rocker arm 10 and the rotation angle of the rocker arm 10 in the rotation direction according to the rotation angles in various directions.

[0037] Specifically, a base 60 is further provided on a side of the circuit board 20 away from the rocker 10 , that is, the circuit board 20 is arranged on the base 60 , and the base 60 provides support and protection for the circuit board 20 , thereby improving the operational stability of the circuit board 20 .

[0038] Specifically, the rocker 10 of this embodiment has a hollow region, within which a reset lever 101 connected to the circuit board 20 is disposed. The bottom of the reset lever 101 is connected to the circuit board 20, and the reset lever 101 is also sheathed with a spring 102. One end of the spring 102 abuts against the bottom portion of the reset lever 101 where it is connected to the circuit board 20. A limiting member 104 is provided within the hollow region of the rocker 10 to form a limiting groove. The other end of the spring 102 abuts within the limiting groove, i.e., the top of the spring 102 is disposed within the limiting groove, thereby achieving an elastic connection between the rocker 10 and the reset lever 101 via the spring 102. The reset lever 101 of this embodiment allows the rocker 10 to be reset. Furthermore, the spring 102 sheathing the reset lever 101 increases the speed at which the rocker 10 is reset, minimizing reset delay.

[0039] The rocker device of this embodiment further includes a button 501 , and a pot piece 502 is provided on a side of the button 501 away from the upper cover 30 ; a button area 204 corresponding to and connected to the pot piece 502 is provided on the first surface of the circuit board 20 .

[0040] Among them, the button 501 has an "concave" structure, that is, a groove is provided on the side of the button 501 away from the circuit board 20, and one of the rotating shafts 403 of the rocker arm structure is provided in the groove of the "concave" structure. When the rocker 10 is pressed, the rocker arm structure presses the button 501 through the rotating shaft 403. After the button 501 is pressed, the button 501 presses the pot piece 502. The pot piece 502 is equivalent to a switch, which triggers the button area 204 in the circuit board 20 through the pot piece 502, thereby triggering the corresponding function. In actual applications, when a user plays a game using a game controller with a joystick 10, some scenes need to be determined through this button 501; for example, if a user needs to select a character image through button 501, the user first selects a character image from a row of character images by shaking the joystick 10 left and right, and then presses the joystick 10 downward, thereby causing button 501 to be pressed, and button 501 presses the pot piece 502. After being pressed, the corresponding button area 204 in the circuit board 20 is triggered, and the user selects this character image.

[0041] Continue to refer Figure 4 、 Figure 5 The first electrode plate assembly 202 includes a plurality of second electrode plates 2022. Figure 4 、 Figure 5 In the description, the number of the second electrode plates 2022 is two as an example. In order to obtain better detection accuracy, the number of the second electrode plates 2022 can also be set to three, four, etc.

[0042] Specifically, when the first conductive plate 4041 rotates with the joystick 10, the relative area between the first conductive plate 4041 and each second plate 2022 changes; the first plate 2021, the first conductive plate 4041, and each second plate 2022 form a first target capacitor; the processor is configured to obtain the capacitance values ​​of multiple first target capacitors and determine the rotation direction and angle of the joystick 10 based on the capacitance values ​​of the multiple first target capacitors. In this embodiment, the first plate 2021 and each second plate 2022 form a first target capacitor. By utilizing the relationship between the capacitance values ​​of the multiple first target capacitors, an algorithm can cleverly eliminate the effects of factors such as changes in the gap between the first plate assembly 202 and the first conductive plate 4041 and changes in the dielectric constant on the rotation angle, achieving better detection results. The greater the number of second plates 2022, the higher the detection accuracy.

[0043] It should be noted that, in this embodiment, the first plate 2021 is an emitter plate, and the second plate 2022 is a receiver plate; in other embodiments, the first plate 2021 may also be a receiver plate, and the second plate 2022 may also be an emitter plate.

[0044] In one embodiment, the number of second pole plates 2022 arranged opposite to the first conductor plate 4041 on the second surface of the bracket 201 is two, and the two second pole plates 2022 are symmetrically arranged on both sides of the first pole plate 2021. The two second pole plates 2022 are symmetrically arranged along the central axis of the first conductor plate 4041, and the central axis of the first conductor plate 4041 is perpendicular to the first surface of the circuit board 20.

[0045] Specifically, when the rocker 10 rotates, the first rotating portion 404 is driven to rotate. Specifically, during the rotation of the first electrode plate 2021, the relative areas between the first conductive plate 4041 and the two second electrode plates 2022 change, and within a certain angular range of the rocker 10, the relative areas are linearly related to the rotation angle. When the rotation angle of the rocker 10 is 0, the relative area between the first conductive plate 4041 and one second electrode plate 2022 is denoted as S1, and the relative area between the first conductive plate 4041 and the other second electrode plate 2022 is denoted as S2. Since the rotation angle of the rocker 10 is 0 at this time, the relative areas between the first conductive plate 4041 and the two second electrode plates 2022 are the same, and therefore S1 and S2 are the same. The target capacitance formed by the first electrode plate 2021, the first conductive plate 4041, and the one second electrode plate 2022 is denoted as C1, and the target capacitance formed by the first electrode plate 2021, the first conductive plate 4041, and the other second electrode plate 2022 is denoted as C2. According to the circuit structure and the chip's driving and detection principles, the relationship between the capacitances C1 and C2 and the joystick 10's rotation angle α can be obtained as follows: C1 = ε(S1-kα) / d, C2 = ε(S2+kα) / d, where ε is the dielectric constant, k is a structural parameter, and d is the distance between the first plate 2021 and the second plate 2022. To eliminate the influence of the dielectric constant ε and the distance d, the data of C1 and C2 can be effectively processed. For example, a Para value can be obtained through a differential operation, Para = (C1-C2) / (C1+C2) = -kα / S1. The final calculated Para value shows that the influence of the dielectric constant ε and the distance d is eliminated. This embodiment can also eliminate the influence of the dielectric constant ε and the distance d between the plates by obtaining the value of C1 / C2, i.e., C1 / C2 = (S1-kα) / (S2+kα).

[0046] like Figure 4 、 Figure 5 As shown, the first electrode plate 2021 and the second electrode plate 2022 are described as a rectangular structure. In order to make the linearity between the target capacitance and the rotation angle of the rocker 10 better, the first electrode plate 2021 and the second electrode plate 2022 can be set to a fan-shaped structure, such as Figure 6 FIG. 1 is a schematic diagram of the planar structure of the first conductor plate on the first rotating part of this embodiment. Figure 7Figure 2 shows a schematic planar structure of the first electrode plate assembly on the bracket of this embodiment. Since both the first conductive plate 4041 and the second electrode plate 2022 are fan-shaped structures, with the centers of the multiple fan-shaped structures overlapping and located on the first or second axis, as the first conductive plate 4041 rotates with the rocker 10, the relative area between the first conductive plate 4041 and each second electrode plate 2022 is linearly related to the rotation angle of the rocker 10. This results in a higher linearity for the Para value or C1 / C2 value calculated using differential calculations, making the calculation structure more accurate and further improving the accuracy of angle measurement for the rocker device. It should be noted that the surface of the first rotating portion 404 on which the first conductive plate 4041 is located may also be fan-shaped.

[0047] It should be noted that, in this embodiment, the relative area between the first electrode plate 2021 and the first conductor plate 4041 is fixed, and the shape of the first electrode plate 2021 can be rectangular, circular, fan-shaped, etc. Even when the first rotating part 404 rotates with the joystick 10, the relative area between the first electrode plate 2021 and the first conductor plate 4041 does not change, so that the change in the first target capacitance is only related to the relative area between the first conductor plate 4041 and the second electrode plate 2022, further improving the accuracy of detection.

[0048] In one embodiment, the number of the plurality of rotating shafts 403 on which the first rotating portion 404 is provided is two, and the two rotating shafts 403 rotate in different directions.

[0049] Continue to refer Figure 1 、 Figure 2 、 Figure 3 The rocker device has four rotating shafts 403, wherein two rotating shafts 403 are provided by the upper rocker arm 401, and the other two rotating shafts 403 are provided by the lower rocker arm 402. The four rotating shafts 403 are respectively arranged around the rocker arm structure. In this embodiment, one of the rotating shafts 403 of the upper rocker arm 401 is provided with a first rotating portion 404, and one of the rotating shafts 403 of the lower rocker arm 402 is provided with a first rotating portion 404. These two first rotating portions 404 are arranged on two adjacent rotating shafts 403; that is, in this embodiment, the first rotating portion 404 is provided on one rotating shaft 403 of the upper rocker arm 401 to detect the rotation angle of the rocker arm 10 about the first axis, and the first rotating portion 404 is provided on one rotating shaft 403 of the lower rocker arm 402 to detect the rotation angle of the rocker arm 10 about the second axis, so that according to 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.

[0050] Since the first rotating parts 404 are only provided at the two rotating shafts in this embodiment, the button 501 can also be provided at the rotating shaft 403 where the rotating parts 404 are not provided. Figure 1 、 Figure 3 As shown, one rotating shaft 403 of the lower rocker arm 402 is provided with a first rotating part 404, and the other rotating shaft 403 is provided in the groove of the "concave" structure of the button 501; in other embodiments, the button 501 can be provided at one rotating shaft 403 of the upper rocker arm 401, that is, one rotating shaft 403 of the upper rocker arm 401 is provided with a first rotating part 404, and the other rotating shaft 403 is provided in the groove of the "concave" structure of the button 501, thereby achieving the same function.

[0051] In other embodiments, for multiple rotating shafts 403, one of the rotating shafts 403 can be set in the groove of the "concave" structure of the button 501, and the other rotating shafts 403 are all provided with corresponding brackets 201, and all brackets 201 can be provided with the first rotating part 404, or only some brackets 201 are provided with the first rotating part 404; for example, there are four rotating shafts 403 in the rocker arm structure, one rotating shaft 403 is set in the groove of the "concave" structure of the button 501, and each of the other three rotating shafts 403 is provided with the first rotating part 404, and the corresponding three brackets 201 are A corresponding first pole plate assembly 202 is set, or, among the other three rotating shafts 403, two rotating shafts 403 are provided with a first rotating part 404, and the corresponding two brackets 201 are both provided with a corresponding first pole plate assembly 202, and the remaining rotating shaft 403 is not provided with a first rotating part 404, and the corresponding bracket 201 is not provided with a corresponding first pole plate assembly 202, but the bracket 201 also has a groove, and the remaining rotating shaft 403 can be set in the groove, so that each rotating shaft 403 of the rocker arm structure is supported by the corresponding bracket 201 or button 501, thereby improving the stability of the rocker arm structure.

[0052] In one embodiment, each of the plurality of rotating shafts 403 is provided with a first rotating portion 404. Figure 84 is a schematic structural diagram of a rocker device according to the present embodiment. The rocker device has four rotating shafts 403, two of which are provided by an upper rocker arm 401, and the other two are provided by a lower rocker arm 402. The four rotating shafts 403 are respectively arranged around the rocker structure. In the present embodiment, each rotating shaft 403 is provided with a first rotating portion 404. Correspondingly, four corresponding brackets 201 are provided on the circuit board 20. That is, in the present embodiment, both rotating shafts 403 of the upper rocker arm 401 are provided with a first rotating portion 404 to detect the rotation angle of the rocker 10 about the first axis, and both rotating shafts 403 of the lower rocker arm 402 are provided with a first rotating portion 404 to detect the rotation angle of the rocker 10 about the second axis. Therefore, based on the rotation angles of the rocker 10 in various directions, not only the rotation direction of the rocker 10 but also the rotation angle of the rocker 10 in the rotation direction can be determined. At the same time, since more first target capacitors are formed in the present embodiment, the accuracy of the angle measurement of the rocker 10 can be further improved.

[0053] In this embodiment, a first conductive plate 4041 and a first plate assembly 202 are provided in the joystick device. The first plate 2021 and the second plate 2022 of the first plate assembly 202 are coupled via the first conductive plate 4041 to form a first target capacitance. When the joystick 10 rotates, the first conductive plate 4041 is driven to rotate via the rotating shaft, causing the relative area between the first conductive plate 4041 and the second plate 2022 of the first plate assembly 202 to change. Consequently, the capacitance of the first target capacitance formed by the first conductive plate 4041, the first plate 2021, and the second plate 2022 changes. Specifically, the capacitance of the first target capacitance varies at different rotation angles. Therefore, the rotation direction and angle of the joystick 10 can be detected by changes in the capacitance of the first target capacitance. Compared to related sensor methods, this embodiment uses capacitance detection to achieve angle measurement of the joystick device. The rotation direction and angle of the joystick 10 can be accurately determined by changes in the first target capacitance, thereby improving the accuracy of angle measurement of the joystick device.

[0054] The present application also relates to a rocker device, such as Figure 9 As shown in FIG. 1 , it is a schematic structural diagram of the rocker device of this embodiment. Figure 10 The figure shows a schematic diagram of the structure of the bracket of the rocker device of this embodiment; the rocker device of this embodiment includes: a rocker 10, a rocker arm structure (not marked in the figure), a processor (not marked in the figure), a circuit board 20, and an upper cover 30 covering the circuit board.

[0055] Specifically, an installation cavity is formed between the upper cover 30 and the circuit board 20, and a limiting hole 301 is provided on the side of the upper cover 30 away from the circuit board 20; a rocker arm structure (including an upper rocker arm 401 and a lower rocker arm 402) is arranged inside the installation cavity, one end of the rocker 10 is connected to the rocker arm structure, and the other end extends out of the upper cover 30 through the limiting hole 301; the rocker arm structure has a plurality of rotating shafts 403, at least one rotating shaft 403 is provided with a first rotating portion 404 along the direction close to the circuit board 20; a bracket 201 corresponding to the first rotating portion 404 is provided on the first surface of the circuit board 20, and the first surface is the surface of the circuit board 20 close to the rocker arm structure; the bracket 201 is provided Inside the mounting cavity, a first conductive plate 4041 is disposed on a surface of the first rotating portion 404 proximal to the bracket 201. A first electrode plate assembly 202 is disposed on a second surface of the bracket 201, facing the first conductive plate 4041. The second surface is the surface of the bracket 201 proximal to the first conductive plate 4041. The first electrode plate assembly 202 includes a first electrode plate 2021 and a second electrode plate 2022. The first electrode plate 2021 and the second electrode plate 2022 are electrically connected to the circuit board 20. The processor is connected to the circuit board 20. When the first conductive plate 4041 rotates with the joystick 10, the relative area between the first conductive plate 4041 and the second electrode plate 2022 changes.

[0056] Specifically, at least one rotating shaft 403 is further provided with a second rotating portion 405 in a direction away from the circuit board 20, and a second conductive plate 4051 is provided on the surface of the second rotating portion close to the bracket. The second surface of the corresponding bracket 201 is further provided with a second electrode assembly 203 arranged opposite to the second conductive plate 4051. The second electrode assembly 203 includes a third electrode 2031 and a fourth electrode 2032. The third electrode 2031 and the fourth electrode 2032 are electrically connected to the circuit board 20. When the second conductive plate 4051 rotates with the rocker 10, the second conductive plate 4051 and the fourth electrode 2032 are in contact with each other. The area changes; the first electrode 2021, the second electrode 2022, and the first conductor plate 4041 form a first target capacitor, and the third electrode 2031, the fourth electrode 2032, and the second conductor plate 4051 form a second target capacitor; a plurality of PIN pins 205 are also provided on the circuit board 20, so as to transmit the signal of the first target capacitor and the signal of the second target capacitor received by the circuit board 20 to the processor, and the processor is used to obtain the capacitance value of the first target capacitor and the capacitance value of the second target capacitor, and determine the rotation direction and angle of the joystick 10 according to the capacitance value of the first target capacitor and the capacitance value of the second target capacitor.

[0057] The difference between this embodiment and the previous embodiment is that this embodiment further includes a second rotating portion 405 , a second conductor plate 4051 , and a second electrode plate assembly 203 . The other structures of this embodiment are substantially the same as those of the previous embodiment, and will not be described again to avoid repetition.

[0058] Specifically, the second electrode plate assembly 203 includes a plurality of fourth electrodes 2032. Figure 9 、 Figure 10 In the description, the number of the fourth plates 2032 is two as an example. In order to obtain better detection accuracy, the number of the fourth plates 2032 can also be set to three, four, etc.

[0059] Specifically, when the second conductor plate 4051 rotates with the joystick 10, the relative area between the second conductor plate 4051 and each fourth electrode plate 2032 changes; the third electrode plate 2031, the second conductor plate 4051, and each fourth electrode plate 2032 each form a second target capacitor; the processor is further configured to obtain the capacitance values ​​of multiple second target capacitors and determine the rotation direction and angle of the joystick 10 based on the capacitance values ​​of the first target capacitor and the second target capacitor. In this embodiment, the third electrode plate 2031 and each fourth electrode plate 2032 form a second target capacitor. By utilizing the relationship between the capacitance values ​​of the multiple second target capacitors, an algorithm can cleverly eliminate the effects of factors such as changes in the gap between the electrode assembly and the conductor plate and changes in the dielectric constant on the rotation angle, achieving better detection results. The greater the number of fourth electrodes 2032, the higher the detection accuracy.

[0060] In one embodiment, the number of fourth pole plates 2032 arranged opposite to the second conductor plate 4051 on the second surface of the bracket 201 is two, and the two fourth pole plates 2032 are symmetrically arranged on both sides of the third pole plate 2031. The two fourth pole plates 2032 are symmetrically arranged along the central axis of the second conductor plate 4051, and the central axis of the second conductor plate 4051 is perpendicular to the first surface of the circuit board 20.

[0061] It should be noted that the relative area between the third electrode plate 2031 and the second conductor plate 4051 of this embodiment is fixed. Even when the second rotating part 405 rotates with the joystick 10, the relative area between the third electrode plate 2031 and the second conductor plate 4051 does not change. Therefore, the change in the second target capacitance is only related to the relative area between the second conductor plate 4051 and the fourth electrode plate 2032, further improving the accuracy of detection.

[0062] In this embodiment, the third plate 2031 is an emitter plate, and the fourth plate 2032 is a receiver plate. In other embodiments, the third plate 2031 may also be a receiver plate, and the fourth plate 2032 may also be an emitter plate.

[0063] Specifically, in this embodiment, the first conductive plate 4041, the second electrode plate 2022, the second conductive plate 4051, and the fourth electrode plate 2032 all have fan-shaped structures. The centers of the multiple fan-shaped structures overlap, and the centers are set on the first axis or the second axis. This arrangement further improves the linearity of the first target capacitance, the second target capacitance, and the rotation angle of the joystick 10. It should be noted that the surface of the second rotating portion 405 on which the second conductive plate 4051 is disposed may also have a fan-shaped structure.

[0064] In one embodiment, the number of the rotating shafts 403 provided with the first rotating portion 404 and the second rotating portion 405 among the plurality of rotating shafts 403 is two, and the rotation directions of the two rotating shafts are different.

[0065] Continue to refer Figure 9 In this embodiment, a second rotating portion 405 is further provided on the rotating shaft 403 on which the first rotating portion 404 is provided. The rocker device has four rotating shafts 403, wherein two rotating shafts 403 are provided from the upper rocker arm 401, and the other two rotating shafts 403 are provided from the lower rocker arm 402. The four rotating shafts 403 are respectively provided around the rocker arm structure. In this embodiment, one of the rotating shafts 403 of the upper rocker arm 401 is provided with the first rotating portion 404 and the second rotating portion 405, and one of the rotating shafts 403 of the lower rocker arm 402 is provided with the first rotating portion 404 and the second rotating portion 405. These two groups of first rotating shafts 403 are provided. A rotating portion 404 and a second rotating portion 405 are provided on two adjacent rotating shafts 403; that is, in this embodiment, a first rotating portion 404 and a second rotating portion 405 are provided on a rotating shaft 403 of the upper rocker arm 401 to detect the rotation angle of the rocker 10 on the first axis, and a first rotating portion 404 and a second rotating portion 405 are provided on a rotating shaft 403 of the lower rocker arm 402 to detect the rotation angle of the rocker 10 on the second axis, so that according to the rotation angle of the rocker 10 in various directions, not only the rotation direction of the rocker 10 can be determined, but also the rotation angle of the rocker 10 in the rotation direction can be determined.

[0066] Since the first rotating part 404 and the second rotating part 405 are only provided at the two rotating shafts 403 in this embodiment, the button 501 can also be provided at the rotating shaft 403 where the rotating part 404 is not provided. Figure 9 As shown, one rotating shaft 403 of the lower rocker arm 402 is provided with a first rotating part 404 and a second rotating part 405, and the other rotating shaft 403 is provided in the groove of the "concave" structure of the button 501; in other embodiments, the button 501 can be provided at a rotating shaft 403 of the upper rocker arm 401, that is, one rotating shaft 403 of the upper rocker arm 401 is provided with a first rotating part 404 and a second rotating part 405, and the other rotating shaft 403 is provided in the groove of the "concave" structure of the button 501, thereby achieving the same function.

[0067] In other embodiments, for multiple rotating shafts 403, one of the rotating shafts 403 can be set in the groove of the "concave" structure of the button 501, and the other rotating shafts 403 are all provided with corresponding brackets 201. The brackets 201 can all be provided with the first rotating part 404 and the second rotating part 405, or only part of the brackets 201 are provided with the first rotating part 404 and the second rotating part 405. For the rotating shaft 403 that is not provided with the first rotating part 404 and the second rotating part 405, the bracket 201 corresponding to the rotating shaft 403 is not provided with the first electrode assembly 202 and the second electrode assembly 203, but the bracket 201 also has a groove, and the corresponding rotating shaft 403 can be set in the groove, so that the rotating shaft 403 is supported by the rotating shaft 403, thereby improving the stability of the rocker arm structure.

[0068] In one embodiment, each of the plurality of rotating shafts 403 is provided with a first rotating portion 404 and a second rotating portion 405. That is, in this embodiment, both rotating shafts 403 of the upper rocker arm 401 are provided with a first rotating portion 404 and a second rotating portion 405 to detect the rotation angle of the rocker 10 about the first axis, and both rotating shafts 403 of the lower rocker arm 402 are provided with a first rotating portion 404 and a second rotating portion 405 to detect the rotation angle of the rocker 10 about the second axis. Thus, based on the rotation angles of the rocker 10 in various directions, not only the rotation direction of the rocker 10 but also the rotation angle of the rocker 10 in the rotational direction can be determined. Furthermore, because this embodiment forms more first target capacitances and second target capacitances, the accuracy of angle measurement of the rocker 10 can be further improved.

[0069] In this embodiment, a second conductive plate 4051 and a second electrode assembly 203 are further provided in the rocker device. The third electrode plate 2031 and the fourth electrode plate 2032 of the second electrode assembly 203 are coupled through the second conductive plate 4051 to form a second target capacitance. When the rocker rotates, the rocker drives the first conductive plate 4041 and the second conductive plate 4051 to rotate through the rotating shaft, so that the relative area between the first conductive plate 4041 and the second electrode plate 2022 in the first electrode assembly 202 changes. 03 changes, the relative area of ​​the fourth electrode 2032 changes, the capacitance value of the first target capacitor formed by the first conductor plate 4041 and the first electrode 2021 and the second electrode 2022 changes, and the capacitance value of the second target capacitor formed by the second conductor plate 4051 and the third electrode 2031 and the fourth electrode 2032 changes. Therefore, the rotation direction and angle of the joystick 10 can be determined more accurately by the changes in the capacitance value of the first target capacitor and the capacitance value of the second target capacitor, thereby further improving the accuracy of the angle measurement of the joystick device.
