[0065] The position detection assembly is arranged on the base 1, and the position detection assembly includes a capacitive component, a chip and corresponding circuits; when the rocker assembly 3 drives the swing assembly to rotate in different directions, the rotation of the swing assembly will change the inductive capacitance value of the capacitive component in the position detection assembly. At this time, the chip will detect the swing position of the rocker assembly 3 in different directions according to the change value of the capacitance, so as to realize the precise control of the swing position of the rocker device in different directions.

[0072] Preferably, a first support shaft 212 is provided on each of the two sides of the first swing arm 21 in the first direction. The middle parts of the two first support shafts on both sides of the first swing arm 21 are respectively rotatably connected to the opposite sides of the upper end of the base 1, and the first swing arm 21 is supported on the base 1; and the end parts of the two first support shafts away from the first swing arm 21 are respectively in rotational contact with the limiting grooves 53 on a pair of opposite side surfaces among the four side surfaces of the housing 51 of the box-shaped structure and are limited within the limiting grooves 53; a second support shaft 222 is provided on each of the two sides of the second swing arm 22 in the second direction.

It should be noted that both the two first support plates 11 and the second support plate 12 are located inside the housing 5. The switch guide 13 is used to install and limit the switch member 14, and the switch member 14 will be described in detail below.

[0079] Refer to Figure 7 and Figures 10 to 12, in an alternative embodiment of the present disclosure, the rocker assembly 3 includes a central shaft 31, a handle sleeve 32, and an elastic member 33. Among them, the bottom end of the central shaft 31 sequentially passes through the first avoidance hole 210 and the second avoidance hole 220 and abuts against the base 1; the handle sleeve 32 is sleeved on the outer side of the top end of the central shaft 31, and the outer side of the bottom end of the handle sleeve 32 is pin-connected to the second swing arm 22, and the top end of the handle sleeve 32 sequentially passes through the second avoidance hole 220, the first avoidance hole 210, and the housing 51 and extends to the outside of the housing 51; the elastic member 33 is disposed between the central shaft 31 and the handle sleeve 32 and is sleeved on the central shaft 31.

[0080] In this embodiment, the handle sleeve 32 is sleeved on the outer side of the top end of the central shaft 31, and the outer edge of the bottom end of the handle sleeve 32 abuts against the outer edge of the bottom end of the central shaft 31; the top end of the overall structure after the handle sleeve 32 and the central shaft 31 are sleeved together sequentially passes through the second avoidance hole 220 and the first avoidance hole 210 and extends to the outside of the housing 51; here, the inner diameter of the handle sleeve 32 is greater than the outer diameter of the central shaft 31 so that the handle sleeve 32 can swing.

[0081] Preferably, the outer diameter of the handle sleeve 32 in the first direction matches the inner diameter of the first avoidance hole 210, so that when the handle sleeve 32 swings in the first direction, it drives the second swing arm 22 to rotate in the second direction, and at this time the first swing arm 21 remains stationary; the outer diameter of the handle sleeve 32 in the second direction matches the inner diameter of the second avoidance hole 220, so that when the handle sleeve 32 swings in the second direction, it drives the first swing arm 21 to rotate in the first direction, and at this time the second swing arm 22 remains stationary. Through the mutual matching of the sizes, only the corresponding swing arm rotates when swinging in one direction, thereby ensuring the accuracy of swing control.

[0082] As Figure 8 shown, preferably, a central arc protrusion 10 is provided at the central position of the base 1, and an arc groove matching the central arc protrusion 10 is provided at the bottom end of the central shaft 31. The arc groove abuts against the central arc protrusion 10 to form an arc contact structure 6. This arc contact structure 6 enables the central shaft 31 to swing more smoothly with the handle sleeve 32 and reduces the swing resistance.

[0083] As Figure 10As shown, in an alternative embodiment of the present disclosure, a third support shaft 321 is respectively provided on both sides of the bottom end of the handle sleeve 32 in the first direction. A connection hole 223 is respectively provided on both sides of the second swing arm 22 in the first direction. The sizes of the two connection holes 223 match the outer diameters of the two third support shafts 321. The handle sleeve 32 is pin-connected to the connection holes 223 on the second swing arm 22 through the third support shafts 321. When the handle sleeve 32 swings in the first direction (that is, at this time, the handle sleeve 32 swings along the X-axis direction and rotates around the second (Y-axis) direction), since the second swing arm 22 is pin-connected to the third support shaft 321 of the handle sleeve 32 through the connection hole 223 in the first direction, the first end of the handle sleeve 32 rotates synchronously with the second swing arm 22 at this time, thereby driving the second swing arm 22 to rotate around the second (Y-axis) direction. When the handle sleeve 32 swings in the second direction (that is, at this time, the handle sleeve 32 swings along the Y-axis direction and rotates around the first (X-axis) direction), the first end of the handle sleeve 32 rotates in the connection hole 223 of the second swing arm 22 through the third support shaft 321, and the first end of the handle sleeve 32 rotates relative to the second swing arm 22 (the second swing arm 22 remains stationary), thereby driving the first swing arm 21 to rotate around the first (X-axis) direction;

[0084] Here, the elastic member 33 is sleeved on the central shaft 31, and a part of the elastic member 33 is sleeved inside the handle sleeve 32, and the elastic member 33 is used to assist in resetting after the handle sleeve 32 and the central shaft 31 perform a swinging action. Preferably, the elastic member 33 includes but is not limited to a spring.

[0085] Referring to Figure 7 and Figure 13 , in an alternative embodiment of the present disclosure, the position detection assembly includes a connection circuit 41, a movable piece, a transmitting electrode plate, a receiving electrode plate, and a position detection chip 43. Among them, the connection circuit 41 is embedded in the base 1, and the switch pressing piece 411 of the connection circuit 41 is arranged on the base 1; the transmitting electrode plate, the receiving electrode plate, and the position detection chip 43 are all arranged on the base 1 and electrically connected to the connection circuit 41; the movable piece is arranged between the transmitting electrode plate and the receiving electrode plate.

[0086] In this embodiment, the connection circuit 41 is arranged along the periphery of the base 1 and embedded in the base 1 to protect the connection circuit 41; the switch pressing piece 411 is electrically connected to the connection circuit 41 and placed on one side of the base 1, and the switch pressing piece 411 is arranged opposite to the second support plate 12, that is, the switch pressing piece 411 and the second support plate 12 are respectively arranged on both sides of the base 1 in the second direction;

[0087] The position detection chip 43 is arranged on the base 1, and the position detection chip 43 is electrically connected to the connection circuit 41;

[0088] Here, both the transmitting electrode plate and the receiving electrode plate are electrode plates; the transmitting electrode plate and the receiving electrode plate are arranged on the same side of the base 1, and the two are spaced apart and arranged opposite to each other to form a capacitive component. The movable piece is arranged between the transmitting electrode plate and the receiving electrode plate and fixedly connected to the first swing arm 21 or the second swing arm 22. When the first swing arm 21 or the second swing arm 22 rotates under the drive of the rocker assembly 3, the movable piece will rotate accordingly, thereby changing the capacitance induction value between the transmitting electrode plate and the receiving electrode plate. At this time, the position detection chip 43 will detect the swing position of the rocker assembly 3 according to the detected changed capacitance induction value.

[0089] Here, the number of the transmitting electrode plates, the receiving electrode plates, and the movable pieces is at least two, and they are arranged in different directions on the base 1 respectively, so as to facilitate detecting the swing positions of the rocker assembly 3 in different directions.

[0090] Preferably, the connection circuit 41, the transmitting electrode plate, the receiving electrode plate, and the position detection chip 43 are integrally formed with the base 1. On the one hand, it is convenient for manufacturing, and on the other hand, it can also ensure the stability of the overall structure of the position detection assembly, and avoid the loosening or falling off of the transmitting electrode plate and the receiving electrode plate during the process of the rocker assembly 3 swinging and driving the swing arm assembly to rotate or when the rocker device is used for a long time, resulting in the inability to perform position detection, thereby ensuring the accuracy of position detection.

[0091] Refer to Figures 1 to 7 , in an alternative embodiment of the present disclosure, the above capacitive rocker device 100 further includes a switch member 14. The switch member 14 is arranged on the other two sides of the base 1 opposite to the second support plate 12. The top end of the switch member 14 is in rotational contact with the other side of the second swing arm 22, and the bottom end of the switch member 14 is in contact with the switch pressing piece 411.

[0092] In this embodiment, the switch member 14 is arranged opposite to the second support plate 12, and the switch member 14 is arranged in the switch guiding member 13. The switch member 14 can be a block structure and is located above the switch pressing piece 411. Preferably, the height of the switch member 14 matches the height of the second support plate 12. More preferably, as Figure 14 shown, a third support groove 143 is formed at the top end of the switch member 14. The third support groove 143 is preferably an arc groove, and the size of the arc groove matches the outer diameter size of the second support shaft 222, and the arc groove is in rotational contact with the second support shaft 222 to cooperate with the second support plate 12 to support the second swing arm 22 on the base 1.

[0093] Preferably, as Figure 14As shown, the switch member 14 includes a support portion 141 and a crimping portion 142. Among them, a third support groove 143 is formed at the top of the support portion 141. The crimping portion 142 is disposed at the bottom of the support portion 141 and fixedly connected to the support portion 141. The crimping portion 142 is located above the switch pressing piece 411 and contacts the switch pressing piece 411.

[0094] By providing the switch member, when the rocker is started to be used, the handle sleeve 32 is pressed, so that the handle sleeve 32 presses the switch member 14 through the second swing arm 22. The bottom end of the switch member 14 squeezes the switch pressing piece 411, so that the built-in connection circuit 41 in the entire base 1 is powered on and activated, so as to detect the swing position of the rocker assembly 3 when the rocker assembly 3 is pressed and swung; when the pressing on the handle sleeve 32 is released, the handle sleeve 32 and the second swing arm 22 return to their original positions under the action of the elastic member 33. At this time, the switch member 14 no longer squeezes the switch pressing piece, and the built-in connection circuit 41 in the base 1 is disconnected to save electric energy; here, the movement amount of the switch member 14 is very small. In the normal state, the bottom end of the switch member 14 is placed on the switch pressing piece 411, but its gravity cannot close the switch pressing piece 411. Only through the pressing force can the switch pressing piece 411 be closed and started, so as to realize power on when using the rocker device and power off when not in use, thereby reducing the power consumption.

[0095] As Figure 13 shown, in an alternative embodiment of the present disclosure, the receiving electrode plate includes a first receiving electrode plate 421 and a second receiving electrode plate 422, and the transmitting electrode plate includes a first transmitting electrode plate 423 and a second transmitting electrode plate 424. Among them, the first receiving electrode plate 421 and the first transmitting electrode plate 423 are arranged opposite to each other along the first direction on one side of the base 1; the second receiving electrode plate 422 and the second transmitting electrode plate 424 are arranged opposite to each other along the second direction on the other side of the base 1.

[0096] In this embodiment, the first receiving electrode plate 421 and the first transmitting electrode plate 423 are arranged opposite to each other and spaced apart on one side of the base 1 to form a first capacitor assembly. The second receiving electrode plate 422 and the second transmitting electrode plate 424 are arranged opposite to each other and spaced apart on the other side of the base 1 to form a second capacitor assembly, and the first capacitor assembly and the second capacitor assembly are perpendicular to each other in the plane where the base 1 is located;

[0097] Preferably, as Figure 8As shown in the figure, a third support plate 15 and a fourth support plate 16 are further provided on the base 1. Among them, the third support plate 15 is parallel and spaced from one of the two first support plates 11 on the same side of the base 1, and the third support plate 15 is located inside the first support plate 11 (closer to the position of the central arc protrusion 10 on the base 1). The fourth support plate 16 is parallel and spaced from the second support plate 12 on the same side of the base 1, and the fourth support plate 16 is located inside the second support plate 12 (closer to the position of the central arc protrusion 10 on the base 1); More preferably, the first capacitor assembly formed by the first receiving electrode plate 421 and the first transmitting electrode plate 423 is arranged between the third support plate 15 and the first support plate 11, and the second capacitor assembly formed by the second receiving electrode plate 422 and the second transmitting electrode plate 424 is arranged between the fourth support plate 16 and the second support plate 12; By providing the third support plate 15 and the fourth support plate 16, the protection of the electrode plates can be achieved;

[0098] Preferably, the height of the third support plate 15 is greater than or equal to the height of the first receiving electrode plate 421 and the first transmitting electrode plate 423, and the height of the third support plate 15 is less than the height of the first support plate 11. While protecting the electrode plates, it can also avoid affecting the first support plate 11 from supporting the first swing arm 21; The height of the fourth support plate 16 is greater than or equal to the height of the second receiving electrode plate 422 and the second transmitting electrode plate 424, and the height of the fourth support plate 16 is less than the height of the second support plate 12. While protecting the electrode plates, it can also avoid affecting the second support plate 12 and the switch member 14 from supporting the second swing arm 22;

[0099] It should be known that in the design structure, the positional relationship between the first receiving electrode plate 421 and the first transmitting electrode plate 423 or between the second receiving electrode plate 422 and the second transmitting electrode plate 424 can be interchanged, and the number of the transmitting electrode plates and the receiving electrode plates can both be changed according to requirements.

[0100] Refer to Figures 1 to 7, in an alternative embodiment of the present disclosure, the movable piece includes a first movable piece 211 and a second movable piece 221. Among them, the first movable piece 211 is disposed on one side of the first swing arm 21, and this side is rotatably connected to one of the two sides of the base 1 along the first direction, and the first movable piece 211 is located between the first receiving electrode plate 421 and the first transmitting electrode plate 423. When the rocker assembly 3 drives the first swing arm 21 to rotate along the first direction, the rotation of the first swing arm 21 drives the first movable piece 211 to swing between the first receiving electrode plate 421 and the first transmitting electrode plate 423; the second movable piece 221 is disposed on one side of the second swing arm 22, and this side is rotatably connected to one of the two sides of the base 1 along the second direction, and the second movable piece 221 is located between the second receiving electrode plate 422 and the second transmitting electrode plate 424. When the rocker assembly 3 drives the second swing arm 22 to rotate along the second direction, the rotation of the second swing arm 22 drives the second movable piece 221 to swing between the second receiving electrode plate 422 and the second transmitting electrode plate 424.

[0101] In this embodiment, the first movable piece 211 is disposed on one side of the first swing arm 21 along the first direction, and the first movable piece 211 is located between the first receiving electrode plate 421 and the first transmitting electrode plate 423. When the rocker assembly 3 swings in the second direction and drives the first swing arm 21 to rotate in the first direction, the rotation of the first swing arm 21 will drive the first movable piece 211 to swing between the first receiving electrode plate 421 and the first transmitting electrode plate 423, so that the inductance value of the inductive capacitance formed between the first receiving electrode plate 421 and the first transmitting electrode plate 423 changes. Furthermore, the position detection chip 43 detects the swing position of the rocker assembly in the second direction according to the changed capacitance inductance value;

[0102] The second movable piece 221 is disposed on one side of the second swing arm 22 along the second direction, and the second movable piece 221 is located between the first receiving electrode plate 421 and the first transmitting electrode plate 423. When the rocker assembly 3 swings in the first direction and drives the second swing arm 22 to rotate in the second direction, the rotation of the second swing arm 22 will drive the second movable piece 221 to swing between the second receiving electrode plate 422 and the second transmitting electrode plate 424, so that the inductance value of the inductive capacitance formed between the second receiving electrode plate 422 and the second transmitting electrode plate 424 changes. Furthermore, the position detection chip 43 detects the swing position of the rocker assembly 3 in the first direction according to the changed capacitance inductance value.
