By forming support grooves on the first support plate 13 and the second support plate 14, the second swing arm 22 is supported on the base 1. Preferably, the first support plate 13 and the second support plate 14 have the same height to ensure the stability during support.

[0075] Refer to Figures 4 to 5 and Figures 8 to 10 , in an alternative embodiment of the present disclosure, the swing assembly includes a first swing arm 21 and a second swing arm 22. Among them, the first swing arm 21 is arranged in the activity space, and both sides of the first swing arm 21 are respectively rotationally connected to the tops of the two first support plates 13 along the first direction. The second swing arm 22 is arranged below the first swing arm 21 and is pin-connected to the bottom end of the rocker assembly 3. Both sides of the second swing arm 22 are rotationally connected to the top of the second support plate 14 along the second direction.

[0076] In this embodiment, the first swing arm 21 and the second swing arm 22 are stacked in the moving space formed by the housing 5 and the base 1, and both the first swing arm 21 and the second swing arm 22 are rotatably connected to the bottom plate 11 so as to rotate in different directions on the bottom plate 11 along with the swing of the rocker assembly 3; preferably, the first swing arm 21 can be integrally arranged as a three-dimensional elliptical structure so as to cover the second swing arm 22 to improve the overall compactness of the device; more preferably, both the two surfaces of the first swing arm 21 and the second swing arm 22 in contact with each other are arranged as arc-shaped surfaces to reduce the resistance during the swinging process and reduce the frictional loss between the swing arms.

[0077] Preferably, a first support shaft 212 is respectively arranged on both sides of the first swing arm 21 in the first direction, and the two first support shafts on both sides of the first swing arm 21 are in rotational contact with the first support grooves 131 on the two first support plates 13 respectively, and the first swing arm 21 is supported on the bottom plate 11; preferably, the outer diameter of the first support shaft 212 matches the size of the first support groove 131;

[0079] Preferably, the two first support shafts can be integrally formed with the first swing arm 21, and the two second support shafts 222 can be integrally formed with the second swing arm 22;

[0080] In the above embodiment, the first swing arm 21 and the second swing arm 22 are both separate components, and both are integrally formed and manufactured, and the two are assembled with each other to form the overall structure of the swing assembly; of course, the first swing arm 21 and the second swing arm 22 of the swing assembly can also be integrally formed.

[0081] In an alternative embodiment of the present disclosure, a first avoidance hole 210 through which the rocker assembly 3 passes is provided on the first swing arm 21, and a second avoidance hole 220 through which the rocker assembly 3 passes is provided on the second swing arm 22. Here, the first avoidance hole 210 is opened along a first direction, and the size of the first avoidance hole 210 in the first direction matches the outer diameter of the rocker assembly 3 in the first direction, so as to facilitate the rocker assembly 3 to drive the first swing arm 21 to rotate in the first direction when swinging in the first direction; the second avoidance hole 220 is opened along a second direction, and the size of the second avoidance hole 220 in the second direction matches the outer diameter of the rocker assembly 3 in the second direction, so as to facilitate the rocker assembly 3 to drive the second swing arm 22 to rotate in the second direction when swinging in the second direction. Here, by providing the first swing arm 21 and the second swing arm 22, the structures of the two are simple, the overall volume of the assembled swing assembly is small, and the avoidance holes provided thereon cooperate with the rocker assembly 3, thereby ensuring the accuracy of swing control in a single direction.

[0082] Referring to Figures 11 to 13 , 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, the second avoidance hole 220 and abuts against the bottom plate 11; 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 5 and extends to the outside of the housing 5; the elastic member 33 is arranged between the central shaft 31 and the handle sleeve 32 and is sleeved on the central shaft 31.

[0083] 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, the first avoidance hole 210, and extends to the outside of the housing 5; here, the inner diameter of the handle sleeve 32 is larger than the outer diameter of the central shaft 31, so that the handle sleeve 32 can swing;

[0084] 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. By matching the sizes with each other, only the corresponding swing arm is driven to rotate when swinging in one direction, thereby ensuring the accuracy of swing control;

[0085] Such asFigure 6 As shown, preferably, a central arc protrusion 111 is provided at the central position on the bottom plate 11, and an arc groove matching the central arc protrusion 111 is provided at the bottom end of the central shaft 31. The arc groove abuts against the central arc protrusion 111 to form an arc contact structure 6 (as shown in Figure 4 and Figure 5 ), and this arc contact structure 6 enables the central shaft 31 to swing more smoothly with the handle sleeve 32, reducing the swing resistance.

[0086] As shown in Figure 12 , in an alternative embodiment of the present disclosure, two third support shafts 321 are respectively provided on both sides of the bottom end of the handle sleeve 32 in the first direction. Two connection holes 223 are 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), at this time, 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;

[0087] Here, the elastic member 33 is sleeved on the central shaft 31, and a part of the elastic member 33 is sleeved in 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.

[0088] As shown in Figure 14 , in an alternative embodiment of the present disclosure, the position detection component 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 bottom plate 11, and the switch pressing piece 411 of the connection circuit 41 is arranged on the top surface of the bottom plate 11; the transmitting electrode plate, the receiving electrode plate, and the position detection chip 43 are all arranged on the top surface of the bottom plate 11 and are electrically connected to the connection circuit 41, and the movable piece is arranged between the transmitting electrode plate and the receiving electrode plate.

[0089] In this embodiment, the connection circuit 41 is arranged along the periphery of the bottom plate 11 and embedded in the bottom plate 11 to protect the connection circuit 41. The switch pressing piece 411 is electrically connected to the connection circuit 41 and disposed on one side of the bottom plate 11, and the switch pressing piece 411 is disposed opposite to the second support plate 14, that is, the switch pressing piece 411 and the second support plate 14 are respectively disposed on both sides of the bottom plate 11 along the second direction.

[0090] The position detection chip 43 is disposed on the bottom plate 11 and electrically connected to the connection circuit 41.

[0091] The transmitting electrode plate and the receiving electrode plate are disposed on the same side of the bottom plate 11, and the two are spaced apart and disposed opposite to each other to form a capacitance component. The movable piece is disposed 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. Here, both the transmitting electrode plate and the receiving electrode plate are electrode plates. When the first swing arm 21 or the second swing arm 22 rotates under the action 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.

[0092] Here, the number of the transmitting electrode plates, the receiving electrode plates, and the movable pieces is at least two, and they are respectively disposed on the bottom plate 11 along different directions to facilitate detecting the swing positions of the rocker assembly 3 in different directions.

[0093] Preferably, the connection circuit 41, the transmitting electrode plate, the receiving electrode plate, and the position detection chip 43 are integrally formed with the bottom plate 11. 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 component, avoiding 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 during the long-term use of the rocker device, resulting in the inability to perform position detection, and thus ensuring the accuracy of position detection.

[0094] Refer to Figures 1 to 8 In an alternative embodiment of the present disclosure, the capacitive rocker device 100 further includes a switch member 17. The switch member 17 is disposed opposite to the second support plate 14 on the other two sides of the bottom plate 11. The top end of the switch member 17 is in rotational contact with the other side of the second swing arm 22, and the bottom end of the switch member 17 is in contact with the switch pressing piece 411.

[0095] In this embodiment, the switch member 17 is disposed on the opposite side of the second support plate 14. The switch member 17 may be a block structure and is located above the switch pressing piece 411. Preferably, the height of the switch member 17 matches the height of the second support plate 14. More preferably, as Figure 15As shown, a third support groove 173 is formed at the top end of the switch member 17. The third support groove 173 is preferably an arc groove, and the size of the arc groove matches the outer diameter of the second support shaft 222. The arc groove is in rotational contact with the second support shaft 222 to cooperate with the second support plate 14 to support the second swing arm 22 on the bottom plate 11;

[0096] Preferably, as Figure 15 shown, the switch member 17 includes a support portion 171 and a crimping portion 172. Among them, the third support groove 173 is formed at the top of the support portion 171, and the crimping portion 172 is disposed at the bottom of the support portion 171 and fixedly connected to the support portion 171. The crimping portion 172 is located above the switch pressing piece 411 and contacts the switch pressing piece 411;

[0097] By providing the switch member 17, when the rocker is first used, the handle sleeve 32 is pressed, so that the handle sleeve 32 presses the switch member 17 through the second swing arm 22. The bottom end of the switch member 17 squeezes the switch pressing piece 411 to activate the built-in connection circuit 41 of the entire bottom plate 11, 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 17 no longer squeezes the switch pressing piece, and the built-in connection circuit 41 of the bottom plate 11 is disconnected to save electric energy; here, the movement amount of the switch member 17 is very small. When the switch member 17 is in the normal state, its bottom end 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 to realize power-on when the rocker device is used and power-off when not in use, thereby reducing the power consumption.

[0100] Preferably, as Figure 6As shown, a third support plate 15 and a fourth support plate 16 are further provided on the bottom plate 11. Among them, the third support plate 15 is parallel and spaced from one of the two first support plates 13 on the same side of the bottom plate 11, and the third support plate 15 is located inside the first support plate 13 (closer to the position of the central arc protrusion 111 on the bottom plate 11). The fourth support plate 16 is parallel and spaced from the second support plate 14 on the same side of the bottom plate 11, and the fourth support plate 16 is located inside the second support plate 14 (closer to the position of the central arc protrusion 111 on the bottom plate 11); 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 13, 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 14; By providing the third support plate 15 and the fourth support plate 16, the protection of the electrode plates can be achieved;

Here, the specific shape of the housing 5 is not limited, and all shapes that can be docked with the base 1 to form an activity space are acceptable; in an achievable example, as Figures 16 to 17 shown, the housing 5 can be a cubic structure.

[0108] In this embodiment, the two first limiting grooves 51 are respectively arranged opposite to the first supporting grooves 131, one of the second limiting grooves 52 is arranged opposite to the second supporting groove 141, the other second limiting groove 52 is arranged opposite to the third supporting groove 173, and the switch member guiding groove 53 is arranged opposite to the switch member 17; preferably, both the first limiting groove 51 and the second limiting groove 52 are arc-shaped grooves, and more preferably, the arc size of the first limiting groove 51 matches the size of the first supporting groove 131, the arc size of the second limiting groove 52 matches the sizes of the second supporting groove 141 and the third supporting groove 173, and the size of the switch member guiding groove 53 matches the size of the switch member 17.

[0110] The capacitive rocker device provided by the above embodiments of the present disclosure is mainly applied to various remote control devices, such as game pads, drones or toy remote controls. Specifically, it includes a housing, a base, a rocker assembly, a swing assembly and a position detection assembly. Among them, the housing is installed on the base and forms an activity space between the housing and the base. The swing assembly is rotatably installed in the activity space. The bottom end of the rocker assembly is arranged in the activity space and abuts against the base. The top end of the rocker assembly sequentially passes through the swing assembly and the housing and extends to the outside of the housing to swing in different directions and drive the swing assembly to rotate in the activity space. The position detection assembly is arranged on the base and is located below the swing assembly. The position detection assembly includes a connection circuit integrally formed with the base, a transmitting electrode plate, a receiving electrode plate and a position detection chip. When the rocker assembly drives the swing assembly to rotate, the swing assembly rotates to drive the movable piece in the position detection assembly to swing between the transmitting electrode plate and the receiving electrode plate, so as to change the induced capacitance value generated between the transmitting electrode plate and the receiving electrode plate. At this time, the position detection chip will accurately detect the swing position of the rocker assembly in different directions in real time according to the generated capacitance change value. By integrally forming the connection circuit, the transmitting electrode plate, the receiving electrode plate and the position detection chip with the base, the stability of the connection between the detection circuit and the electrode plate in the rocker device can be improved, and the accuracy of position detection can be further ensured to achieve more precise control.

[0111] The above are the preferred embodiments of the present disclosure. It should be noted that for those of ordinary skill in the art in the technical field, without departing from the principle of the present disclosure, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present disclosure.
