[0034] The bracket 201 of this embodiment is provided with 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 to each other; 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 a side of the upper rocker arm 401 close to the upper cover 30, and a second sliding opening 406 is provided on a side of the lower rocker arm 402 close to the upper cover 30, and 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 matching the positioning hole 407 is provided at 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 follow the rocker arm 10 to rotate along the second axis, and the upper rocker arm 401 does not rotate at this time; the rocker arm 10 can also rotate in the second sliding opening 406 and drive the upper rocker arm 401 to follow the rocker arm 10 to rotate along the first axis, and the lower rocker arm 402 does not rotate at this time; the movement of the rocker arm 10 is achieved in this way, and the first pole plate 2021 and the second pole plate 2022 corresponding to the first rotating part 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 pole plate 2021 and the second pole plate 2022 corresponding to the first rotating part 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 angles 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 operating stability of the circuit board 20 .

[0038] Specifically, the rocker 10 of this embodiment is a hollow area, and a reset rod 101 connected to the circuit board 20 is arranged in the hollow area, and the bottom of the reset rod 101 is connected to the circuit board 20. The reset rod 101 is also sleeved with a spring 102, and one end of the spring 102 is against the bottom of the reset rod 101 connected to the circuit board 20. The rocker 10 is provided with a limiting member 104 inside the hollow area to form a limiting groove, and the other end of the spring 102 is against the limiting groove, that is, the top of the spring 102 is arranged inside the limiting groove, so that the rocker 10 and the reset rod 101 are elastically connected through the spring 102. In this embodiment, by providing the reset rod 101, the rocker 10 can be reset, wherein the reset rod 101 is also sleeved with the spring 102, and by sleeved with the spring 102, the speed of resetting the rocker 10 is increased, and the reset delay is reduced as much as possible.

[0039] The rocker device of this embodiment further includes a button 501 , and a pot piece 502 is disposed 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 disposed on the first surface of the circuit board 20 .

[0040] Among them, the button 501 is in 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 set 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 using this button 501; for example, if a user needs to select a character using button 501, the user first selects a character from a row of characters by shaking the joystick 10 left and right, and then presses the joystick 10 downward, thereby pressing button 501, which in turn presses pot piece 502. After being pressed, the corresponding button area 204 in the circuit board 20 is triggered, and the user selects the character.

[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 conductor plate 4041 rotates with the rocker 10, the relative area between the first conductor plate 4041 and each second plate 2022 changes; the first plate 2021, the first conductor plate 4041 and each second plate 2022 form a first target capacitor; the processor is used to obtain the capacitance values ​​of multiple first target capacitors, and determine the rotation direction and angle of the rocker 10 according to the capacitance values ​​of 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 multiple first target capacitors, the algorithm can cleverly eliminate the influence of factors such as the gap change between the first plate assembly 202 and the first conductor plate 4041 and the dielectric constant change on the rotation angle, thereby achieving a better detection effect. Among them, the more the number of second plates 2022, the higher the accuracy of the detection.

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

[0044] In one embodiment, the number of second pole plates 2022 arranged on the second surface of the bracket 201 opposite to the first conductor plate 4041 is two, and the two second pole plates 2022 are symmetrically arranged on both sides of the first pole plate 2021, and 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 part 404 is driven to rotate; specifically, during the rotation of the first electrode plate 2021, the relative areas of the first conductor plate 4041 and the two second electrodes 2022 are changed, and within a certain angle range, the relative area and the rotation angle of the rocker 10 are linearly related. When the rotation angle of the rocker 10 is 0, the relative area of ​​the first conductor plate 4041 and one second electrode plate 2022 is recorded as S1, and the relative area of ​​the first conductor plate 4041 and the other second electrode plate 2022 is recorded as S2. Since the rotation angle of the rocker 10 is 0 at this time, the relative areas of the first conductor plate 4041 and the two second electrodes 2022 are the same, so S1 and S2 are the same; and the target capacitance formed by the first electrode plate 2021, the first conductor plate 4041 and one second electrode plate 2022 is recorded as C1, and the target capacitance formed by the first electrode plate 2021, the first conductor plate 4041 and the other second electrode plate 2022 is recorded as C2. According to the circuit structure and the driving and detection principles of the chip, the relationship between the capacitance C1 and C2 and the rotation angle α of the rocker 10 can be obtained as follows: C1 = ε (S1-kα) / d, C2 = ε (S2 + kα) / d, ε is the dielectric constant, k is a parameter related to the structure, and d is the distance between the first plate 2021 and the second plate 2022. In order to eliminate the influence of the dielectric constant ε and the distance d, the data of C1 and C2 can be effectively processed, such as obtaining a Para value through differential operation, Para = (C1-C2) / (C1 + C2) = -kα / S1. It can be seen from the final calculated Para value 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, that is, 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 by taking a rectangular structure as an example. 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 7As shown, it is a schematic diagram of the planar structure of the first electrode assembly of this embodiment on the bracket. Since the first conductor plate 4041 and the second electrode plate 2022 are both fan-shaped structures, the centers of the circles of the multiple fan-shaped structures overlap, and the centers of the circles are set on the first axis or the second axis. When the first conductor plate 4041 rotates with the rocker 10, the relative area of ​​the first conductor plate 4041 and each second electrode plate 2022 is linearly related to the rotation angle of the rocker 10. The Para value or C1 / C2 value calculated by differential operation has higher linearity, and the calculation structure is more accurate, which further improves the accuracy of the angle measurement of the rocker device. It should be noted that the surface of the first rotating part 404 where the first conductor plate 4041 is set can also be a fan-shaped structure.

[0047] It should be noted that, in the present 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 may 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 of the first target capacitance is only related to the relative area between the first conductor plate 4041 and the second electrode plate 2022, thereby further improving the accuracy of detection.

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

[0050] Since the first rotating parts 404 are only provided at 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.

[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 key 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 key 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 provided, 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 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 provided 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 8As shown, it is a schematic diagram of the structure of the rocker device of this embodiment, wherein 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, and the four rotating shafts 403 are respectively provided around the rocker structure, and each rotating shaft 403 of this embodiment is provided with a first rotating portion 404, and correspondingly, four corresponding brackets 201 are provided on the circuit board 20, that is, in this embodiment, the two 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 on the first axis, and the two 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 on the second axis, so that according to the rotation angle of the rocker 10 in each direction, 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, and at the same time, since more first target capacitors are formed in this embodiment, the accuracy of the angle measurement of the rocker 10 can be further improved.

[0053] In this embodiment, a first conductor plate 4041 and a first electrode plate assembly 202 are provided in the rocker device. The first electrode plate 2021 and the second electrode plate 2022 of the first electrode plate assembly 202 are coupled through the first conductor plate 4041 to form a first target capacitor. When the rocker 10 rotates, the rocker 10 drives the first conductor plate 4041 to rotate through the rotating shaft, so that the relative area between the first conductor plate 4041 and the second electrode plate 2022 in the first electrode plate assembly 202 changes, and the capacitance value of the first target capacitor formed by the first conductor plate 4041 and the first electrode plate 2021 and the second electrode plate 2022 changes, that is, at different rotation angles, the capacitance value of the first target capacitor is different, so that the rotation direction and angle of the rocker 10 can be detected by the change of the capacitance value of the first target capacitor. Compared with the sensor method in the related art, the present embodiment realizes the angle measurement of the rocker device through the capacitance detection method, and can accurately determine the rotation direction and angle of the rocker 10 through the change of the first target capacitance, thereby improving the accuracy of the angle measurement of the rocker device.

[0056] Specifically, at least one rotating shaft 403 is also provided with a second rotating portion 405 in a direction away from the circuit board 20, and a second conductor plate 4051 is provided on the surface of the second rotating portion close to the bracket, and a second electrode plate assembly 203 arranged opposite to the second conductor plate 4051 is also provided on the second surface of the corresponding bracket 201, and the second electrode plate assembly 203 includes a third electrode plate 2031 and a fourth electrode plate 2032; the third electrode plate 2031 and the fourth electrode plate 2032 are electrically connected to the circuit board 20; when the second conductor plate 4051 rotates with the rocker 10, the second conductor plate 4051 and the fourth electrode plate 2032 are opposite to 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 is further provided with a second rotating part 405, a second conductor plate 4051, and a second electrode plate assembly 203. The other structures of this embodiment and the previous embodiment are substantially the same, and will not be described again to avoid repetition.

[0058] Specifically, the second electrode assembly 203 includes a plurality of fourth electrodes 2032. Fig. 9 , Fig.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 rocker 10, the relative area between the second conductor plate 4051 and each fourth plate 2032 changes; the third plate 2031, the second conductor plate 4051 and each fourth plate 2032 form a second target capacitor; the processor is also used to obtain the capacitance values ​​of multiple second target capacitors, and determine the rotation direction and angle of the rocker 10 according to the capacitance values ​​of the first target capacitor and the second target capacitor. The third plate 2031 of this embodiment forms a second target capacitor with each fourth plate 2032. By utilizing the relationship between the capacitance values ​​of multiple second target capacitors, the algorithm can cleverly eliminate the influence of factors such as the gap change between the plate assembly and the conductor plate and the dielectric constant change on the rotation angle, thereby achieving a better detection effect. Among them, the more the number of fourth plates 2032, the higher the accuracy of the detection.

[0060] In one embodiment, the number of fourth pole plates 2032 arranged on the second surface of the bracket 201 opposite to the second conductor plate 4051 is two, and the two fourth pole plates 2032 are symmetrically arranged on both sides of the third pole plate 2031, and 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, in the present embodiment, the relative area between the third electrode plate 2031 and the second conductor plate 4051 remains fixed, and even when the second rotating portion 405 rotates with the joystick 10, the relative area between the third electrode plate 2031 and the second conductor plate 4051 does not change, so that the change of the second target capacitance is only related to the relative area between the second conductor plate 4051 and the fourth electrode plate 2032, thereby 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, the first conductor plate 4041, the second electrode plate 2022, the second conductor plate 4051, and the fourth electrode plate 2032 of the present embodiment are all fan-shaped structures, and the centers of the multiple fan-shaped structures overlap, and the centers of the circles are set on the first axis or the second axis, so that through this arrangement, the linearity of the first target capacitance, the second target capacitance and the rotation angle of the rocker 10 is further improved. It should be noted that the surface of the second rotating part 405 on which the second conductor plate 4051 is set can also be a fan-shaped structure.

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

The two sets of the first rotating shafts 403 are provided with the first rotating part 404 and the second rotating part 405. A rotating portion 404 and a second rotating portion 405 are arranged on two adjacent rotating shafts 403; that is, in this embodiment, a first rotating portion 404 and a second rotating portion 405 are arranged on a rotating shaft 403 of an upper rocker arm 401 to detect the rotation angle of the rocker 10 about the first axis, and a first rotating portion 404 and a second rotating portion 405 are arranged on a rotating shaft 403 of a lower rocker arm 402 to detect the rotation angle of the rocker 10 about 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. Fig. 9 As shown, a rotating shaft 403 of the lower rocker arm 402 is provided with a first rotating part 404 and a second rotating part 405, and another rotating shaft 403 is arranged in a groove of the "concave" structure of the key 501; in other embodiments, the key 501 can be arranged at a rotating shaft 403 of the upper rocker arm 401, that is, a rotating shaft 403 of the upper rocker arm 401 is provided with a first rotating part 404 and a second rotating part 405, and another rotating shaft 403 is arranged in the groove of the "concave" structure of the key 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 pole plate assembly 202 and the second pole plate 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, the two 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 on the first axis, and the two 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 on the second axis, so that 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 according to the rotation angle of the rocker 10 in each direction, and at the same time, because more first target capacitors and second target capacitors are formed in this embodiment, the accuracy of the angle measurement of the rocker 10 can be further improved.

The third electrode plate 2031 and the fourth electrode plate 2032 of the second electrode assembly 203 are coupled through the second conductor plate 4051 to form a second target capacitance. When the rocker rotates, the rocker drives the first conductor plate 4041 and the second conductor plate 4051 to rotate through the rotating shaft, so that the relative area between the first conductor plate 4041 and the second electrode plate 2022 in the first electrode assembly 202 changes, and the second conductor plate 4051 and the second electrode assembly 202 are relatively close to each other. 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, so that the rotation direction and angle of the joystick 10 can be more accurately determined 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.
