[0037] With reference to the foregoing Figure 1 , Figure 2 , Figure 3 , the rocker structure of the embodiment includes a lower rocker 302 and an upper rocker 301 covering the lower rocker 302. The upper rocker 301 rotates along a first axis following the rocker 10, and the lower rocker 302 rotates along a second axis following the rocker 10. The first axis and the second axis are arranged perpendicularly.

[0038] Specifically, in the rotating process of the rocker 10, the rocker 10 can rotate in the first sliding opening and drive the lower rocker 302 to rotate along the second axis following the rocker 10, and at this time, the upper rocker 301 does not rotate. The rocker 10 can also rotate in the second sliding opening and drive the upper rocker 301 to rotate along the first axis following the rocker 10, and at this time, the lower rocker 302 does not rotate.

Thus, the rotation angle of the rocker 10 in each direction is detected, and then the rotation direction of the rocker 10 and the rotation angle of the rocker 10 in the rotation direction are determined according to the rotation angle in each direction.
[0039] Specifically, the circuit board 20 is provided with a base 50 away from one side of the rocker 10, that is, the circuit board 20 is arranged on the base 50, the base 50 provides support and protection for the circuit board 20, and the stability of the operation of the circuit board 20 is improved; and an upper cover 60 is further arranged, which is used for covering the rocker structure and the support, and the upper cover 60 is further provided with an opening, and one end of the rocker 10 extends out of the upper cover 60 through the opening.
[0040] Specifically, the rocker 10 of the embodiment is a hollow region, and a reset rod 101 connected with the circuit board 20 is arranged in the hollow region, the bottom of the reset rod 101 is connected with the circuit board 20, the reset rod 101 is further sleeved with a spring 102, one end of the spring 102 abuts against the bottom of the reset rod 101 connected with the circuit board 20, and the rocker 10 is provided with a limiting piece 104 inside the hollow region 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 arranged inside the limiting groove, so that the rocker 10 and the reset rod 101 are elastically connected through the spring 102. Through the arrangement of the reset rod 101, the reset of the rocker 10 can be realized, wherein the reset rod 101 is further sleeved with the spring 102, and through the sleeving of the spring 102, the speed of the reset of the rocker 10 is improved, and the reset delay is reduced as much as possible.
[0041] Specifically, the rocker device of the embodiment further comprises a button 401, and the button 401 is provided with a pot piece 402 on the side close to the circuit board 20; and the first surface of the circuit board 20 is provided with a button area 202 corresponding to the pot piece 402.
[0042] Specifically, the rocker device of the embodiment further comprises a button 401, and the button 401 is provided with a pot piece 402 on the side close to the circuit board 20; and the first surface of the circuit board 20 is provided with a button area 202 corresponding to the pot piece 402.
[0043] Continuing to refer to Figure 7 to Figure 9 The second support 3052 of the support 305 of the embodiment is provided with two second polar plates 3054. Figure 7For better detection accuracy, the number of the second electrode plates 3054 can also be set to three, four, etc.
[0044] Specifically, in the case that the rotating part follows the rotation of the rocker 10, the medium baffle 3043 follows the rotation of the rocker 10, and the overlapping area of the medium baffle 3043 with each second electrode plate 3054 changes; the medium baffle 3043 and each second electrode plate 3054 form a target capacitor; the processor is configured to obtain the capacitance values of the plurality of target capacitors, and determine the rotation direction and angle of the rocker 10 according to the plurality of capacitance values. In the embodiment, the medium baffle 3043 and each second electrode plate 3054 form a target capacitor, and through the relationship between the capacitance values of the plurality of target capacitors, the algorithm can cleverly eliminate the influence of the gap change between the electrode plates and the dielectric coefficient change on the rotation angle, and better detection effect is achieved. The more the number of the second electrode plates 3054, the higher the detection accuracy.
[0045] It should be noted that the first electrode plate 3053 is a transmitting electrode plate, and the second electrode plate 3054 is a receiving electrode plate in the embodiment; in other embodiments, the first electrode plate 3053 can also be a receiving electrode plate, and the second electrode plate 3054 can also be a transmitting electrode plate.
[0046] In one embodiment, the two second electrode plates 3054 are symmetrically arranged along the central axis of the first electrode plate 3053, and the central axis of the first electrode plate 3053 is perpendicular to the first surface of the circuit board 20.
[0047] Specifically, when the rocker 10 rotates to drive the medium baffle 3043 to rotate, the overlapping area of the medium baffle 3043 with the first electrode plate 3053 does not change, and the overlapping area of the medium baffle 3043 with the two second electrode plates 3054 changes, and within a certain angle range of the rocker 10, the overlapping area and the rotation angle are in a linear relationship; the target capacitor formed by the first electrode plate 3053 and one second electrode plate 3054 is denoted as C1, and the target capacitor formed by the first electrode plate 3053 and the other second electrode plate 3054 is denoted as C2; when the medium baffle 3043 rotates counterclockwise or clockwise, the facing area of the medium baffle 3043 with one second electrode plate 3054 decreases, resulting in a decrease in C1; the facing area of the medium baffle 3043 with the other second electrode plate 3054 increases, resulting in an increase in C2; by detecting the signals of C1 and C2, the rotation angle can be calculated.
[0048] In the above figure, the medium baffle 3043 and the second electrode plate 3054 are taken as an example in a rectangular structure. In order to make the linearity of the target capacitance and the rotation angle of the rocker 10 better, the medium baffle 3043 and the second electrode plate 3054 can be set as a fan-shaped structure, so that the change amount of the overlapping area of the medium baffle 3043 and each second electrode plate 3054 during the rotation of the medium baffle 3043 following the rocker 10 is more close to a linear relationship, and the accuracy of the angle measurement of the rocker device is further improved. It should be noted that the surface area of the medium baffle 3043 in the embodiment can be greater than the surface area of the first electrode plate 3053. In other embodiments, the surface area of the medium baffle 3043 can also be less than the surface area of the first electrode plate 3053, wherein the shape of the first electrode plate 3053 is not limited as long as the overlapping area of the medium baffle 3043 and the first electrode plate 3053 is unchanged during the rotation process.
[0049] In one embodiment, the number of rotation shafts 303 provided with the rotation part among the plurality of rotation shafts 303 is two, and the rotation directions of the two rotation shafts 303 are different. It is continued to refer to Figure 1 、 Figure 2 、 Figure 3 , the rocker device has four rotation shafts 303, wherein two rotation shafts 303 are provided by the upper rocker arm 301, and the other two rotation shafts 303 are provided by the lower rocker arm 302. The four rotation shafts 303 are respectively arranged around the rocker arm structure. One of the rotation shafts 303 of the upper rocker arm 301 in the embodiment is provided with a rotation part, and one of the rotation shafts 303 of the lower rocker arm 302 is provided with a rotation part. The two rotation parts are arranged on two adjacent rotation shafts 303. That is, the rotation part is arranged on one rotation shaft 303 of the upper rocker arm 301 in the embodiment to detect the rotation angle of the rocker 10 on the first axis, and the rotation part is arranged on one rotation shaft 303 of the lower rocker arm 302 to detect the rotation angle of the rocker 10 on the second axis. Therefore, according to the rotation angles 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.
[0050] Since the embodiment only provides two sets of capacitance structures formed by the first electrode plate 3053 and the second electrode plate 3054, a button 501 can also be arranged at the rotation shaft 303 without the rotation part, as shown in Figure 1 、 Figure 2 , one of the rotation shafts 303 of the lower rocker arm 302 is provided with a rotation part, and the other rotation shaft 303 is arranged in the groove of the "concave" structure of the button 501. In other embodiments, the button 501 can be arranged at one rotation shaft 303 of the upper rocker arm 301, that is, one rotation shaft 303 of the upper rocker arm 301 is provided with a rotation part, and the other rotation shaft 303 is arranged in the groove of the "concave" structure of the button 501, so as to realize the same function.

For example, the rocker arm structure has four rotating shafts 303, one rotating shaft 303 is arranged in the groove of the "concave" structure of the key 501, and the other three rotating shafts 303 are each provided with a rotating part, and the corresponding three supports 305 are each provided with a corresponding first polar plate 3053 and a second polar plate 3054. Alternatively, of the other three rotating shafts 303, two rotating shafts 303 are provided with rotating parts, and the corresponding two supports 305 are each provided with a corresponding first polar plate 3053 and a second polar plate 3054, and the remaining one rotating shaft 303 is not provided with a rotating part, and the corresponding support 305 is also not provided with a first polar plate 3053 and a second polar plate 3054. The support 305 is arranged on the base 50, and the circuit board 20 is provided with a corresponding opening. The support 305 extends from the opening, and the support 305 has a groove. The remaining one rotating shaft 303 can be arranged in the groove, so that each rotating shaft of the rocker arm structure has a corresponding support or key support, improving the stability of the rocker arm structure.
[0052] In one embodiment, each of the multiple rotating shafts 303 is provided with a first polar plate 3053 in a direction close to the circuit board 20. As shown in Figure 1 、 Figure 2 The rocker arm structure has four rotating shafts 303, two of which are arranged by the upper rocker arm 301, and the other two are arranged by the lower rocker arm 302.

Therefore, according to the rotation angle of the rocker 10 in each direction, not only can the rotation direction of the rocker 10 be determined, but also the rotation angle of the rocker 10 in the rotation direction can be determined. At the same time, since four target capacitances are formed in this embodiment, the accuracy of the angle measurement of the rocker 10 can be further improved.
[0053] The embodiment of the application sets the medium baffle 3043 between the first limiting piece 3041 and the second limiting piece 3042, sets the support 305 as the first support 3051 and the second support 3052 connected with the first support 3051, forms a groove between the first support 3051 and the second support 3052, when the rotating part is set in the groove, the first limiting piece 3041 abuts against the first support 3051, the second limiting piece 3042 abuts against the second support 3052, so that the relative position of the medium baffle 3043 and the first polar plate 3053 and the second polar plate 3054 is fixed, even if the rocker shaft moves axially, the medium baffle 3043 will not rub against the first polar plate 3053 and the second polar plate 3054, the stability of the rocker structure is improved, and the angle detection accuracy of the capacitive rocker is improved.
