[0056] In the following description, in order to clearly show the structure and working mode of the present invention, many directional terms will be used for description. However, words such as "front", "rear", "left", "right", "outer", "inner", "outward", "inward", "up", "down", etc. should be understood as convenient terms and should not be understood as restrictive terms.

[0057] Refer to Figures 1 to 14, an embodiment of the present invention provides a capacitive rocker device, which includes a main housing, a swing arm assembly, a rocker assembly, and a position monitoring assembly. Among them, the main housing includes a housing 11 and a base 12, and the swing arm assembly includes a first swing arm 21 and a second swing arm 22. The rocker assembly includes a central shaft 31, a handle sleeve 32, and an elastic member 33. The position monitoring assembly includes two sets of capacitive structures, namely a first capacitive structure 40a and a second capacitive structure 40b. Specifically, each set of capacitive structures 40 includes a movable piece and two electrode plates.

[0058] After the housing 11 is connected to the base 12, a hollow cavity is formed. A relatively large inner and outer connected housing avoidance opening can be provided on the top surface of the housing 11 to facilitate the rocker assembly to swing in the first direction or the second direction after extending out of the housing 11.

[0059] The first swing arm 21 is arranged in the hollow cavity and is rotatably connected to the main housing around the first direction. The first swing arm 21 can be rotatably connected to the housing 11 or can be rotatably connected to two first support plates 121 arranged along the first direction on the base 12. Among them, the first direction is Figure 5 the X-axis direction in

[0060] The second swing arm 22 is arranged in the hollow cavity and is rotatably connected to the main housing around the second direction. The second swing arm 22 can be rotatably connected to the housing 11 or can be rotatably connected to two second support plates 122 arranged along the second direction on the base 12. Among them, the second direction is Figure 5 the Y-axis direction in

[0061] and the second direction is perpendicular to the first direction. The rocker assembly is arranged in the hollow cavity, the bottom end abuts against the bottom end inside the main housing, and the top end passes through the first swing arm 21 and the second swing arm 22 and extends out of the top surface of the main housing. The first swing arm 21 and the second swing arm 22 can be driven by the rocker assembly to swing around the first direction and the second direction.

[0062] The two sets of capacitive structures are arranged in the hollow cavity. The two electrode plates 42a in the first capacitive structure 40a are arranged opposite to each other, and the movable piece 41a in the first capacitive structure 40a is located between the two electrode plates 42a. The two electrode plates 42b in the second capacitive structure 40b are arranged opposite to each other, and the movable piece 41b in the second capacitive structure 40b is located between the two electrode plates 42b.

[0063] The movable piece 41a is fixedly connected to the first swing arm 21. After the two electrode plates 42a are energized, a first inductive capacitive structure is formed. When the rocker assembly drives the first swing arm 21 to swing around the first direction, when the movable piece 41a rotates with the rocker assembly driving the first swing arm 21, the movable piece 41a will cause the capacitance value of the first inductive capacitive structure to change. According to this change, the swing position of the rocker assembly around the first direction can be monitored.

[0064] The movable piece 41b is fixedly connected to the second swing arm 22. After the two electrode plates 42b are energized, a second induction capacitance structure is formed. When the rocker assembly drives the second swing arm 22 to swing around the second direction, and the movable piece 41b rotates with the rocker assembly driving the second swing arm 22, the capacitance value of the second induction capacitance structure will change. According to this change, the swing position of the rocker assembly around the second direction can be monitored.

[0065] In one embodiment, at least the inner electrode plate is provided with an electrode plate center hole.

[0066] Refer to Figure 3 、 Figures 7 to 10 As shown in FIGS.

[0067] Refer to Figure 4 、 Figures 7 to 14 As shown in FIGS.

[0068] In one embodiment, the movable piece is a wedge-shaped structure with a large thickness value at one end and a small thickness value at the other end.

[0069] Specifically, the movable piece can be a wedge-shaped structure with a gradually increasing thickness from one end to the other end.

[0070] The movable piece can be a sheet-like body with a sector cross-section. The movable piece 41a is arranged on the outer peripheral upper surface of the first support shaft 211, and the movable piece 41b is arranged on the outer peripheral upper surface of the second support shaft 221.

[0071] In one embodiment, refer to Figures 7 to 14, a power - on pin 421 is provided at the bottom end of each electrode plate, and the power - on pin 421 is connected to the internal circuit of the base 12 or directly passes through the base 12 and is connected to an external circuit provided below the base 12.

[0072] The internal circuit of the base or the external circuit supplies power to the electrode plate through the power - on pin 421.

[0073] In one embodiment, the capacitive structure further includes an outer shell and an inner shell. The outer shell, the inner shell and the main shell are all detachably connected. An internal cavity is formed by enclosing between the outer shell and the inner shell. The two electrode plates and the movable piece are all located in the internal cavity, and at least the inner shell is provided with a central hole of the shell.

[0074] Taking the first capacitive structure 40a as an example, refer to Figure 3 , the first capacitive structure 40a includes an outer shell 43a and an inner shell 44a. The outer shell 43a, the inner shell 44a and the main shell are all detachably connected. An internal cavity is formed by enclosing between the outer shell 43a and the inner shell 44a. The two electrode plates 42a and the movable piece 41a are all located in the internal cavity, and at least the inner shell 44a is provided with a central hole of the shell.

[0075] Taking the second capacitive structure 40b as an example, refer to Figure 3 , Figure 11 and Figure 12 , the second capacitive structure 40b includes an outer shell 43b and an inner shell 44b. The outer shell 43b, the inner shell 44b and the main shell are all detachably connected. An internal cavity is formed by enclosing between the outer shell 43b and the inner shell 44b. The two electrode plates 42b and the movable piece 41b are all located in the internal cavity, and at least the inner shell 44b is provided with a central hole of the shell.

[0076] The first support shaft 211 sequentially passes through the central hole of the shell and the central hole of the electrode plate in the first capacitive structure 40a and is fixedly connected to the movable piece 41a in the first capacitive structure 40a.

[0077] The second support shaft 221 sequentially passes through the central hole of the shell and the central hole of the electrode plate in the second capacitive structure 40b and is fixedly connected to the movable piece 41 in the second capacitive structure 40b.

[0078] In one embodiment, both of the two electrode plates 42 in the capacitive structure are provided with central holes of the electrode plate, and both the outer shell and the inner shell in the capacitive structure are provided with central holes of the shell.

[0079] In one embodiment, both the outer shell and the inner shell are snap - fitted and connected to the outer shell 11 through snap - fasteners.

[0080] Taking the second capacitive structure 40b as an example, refer to Figure 11And Figure 12 On the outer shell 43b, an outer buckle 431 is provided. The outer shell 43b is snap-fitted and connected to the outer casing 11 outside it through the outer buckle 431. On the inner shell 44b, an inner buckle 441 is provided. The inner shell 44b is snap-fitted and connected to the outer casing 11 outside it through the inner buckle 441.

[0081] In one embodiment, one of the two electrode plates is fixedly installed in the installation groove on the inner wall of the outer shell, and the other of the two electrode plates is fixedly installed in the installation groove on the inner wall of the inner shell.

[0082] In one embodiment, referring to Figure 3 , Figures 5 to 9 , both ends of the first swing arm 21 in the first direction are respectively provided with a first support shaft 211. The first swing arm 21 is pin-connected to two first support plates 121 on the base 12 through the first support shaft 211.

[0083] Referring to Figures 4 to 9 , both ends of the second swing arm 22 in the second direction are respectively provided with a second support shaft 221. The second swing arm 22 is pin-connected to the second support plate 122 on the base 12 through the second support shaft 221.

[0084] The pin connection in this embodiment is a rotational connection of the shaft in the hole. Specifically in implementation, shaft holes are respectively provided on the first support plate 121 and the second support plate 122. The shaft hole can be a closed hole, or it can also be an opening with an open top as shown in Figure 9 . The first support shaft 211 or the second support shaft 221 is inserted into the shaft hole or placed on the opening and can rotate on the shaft hole or the opening. That is to say, the two are not fixedly connected, but rotationally connected.

[0085] In one embodiment, referring to Figure 6 , a first avoidance hole 212 for the rocker assembly to pass through is provided on the first swing arm 21. The length direction of the first avoidance hole 212 is the first direction. A second avoidance hole 222 for the rocker assembly to pass through is provided on the second swing arm 22. The length direction of the second avoidance hole 222 is the second direction. The second swing arm 22 is located below the first swing arm 21.

[0086] Referring to Figure 3 and Figure 5 , the bottom end of the central shaft 31 abuts against the central position of the base 12. The handle sleeve 32 is sleeved on the outer side of the upper part of the central shaft 31. The upper part of the handle sleeve 32 sequentially passes through the second avoidance hole 222, the first avoidance hole 212 and the outer casing 11 and extends out of the top of the outer casing 11. The lower part of the handle sleeve 32 is restricted below the first swing arm 21. The elastic member 33 is arranged between the central shaft 31 and the handle sleeve 32 and is sleeved on the outer side of the central shaft 31.

[0087] When the handle sleeve 32 swings in the first direction, it drives the first swing arm 21 to rotate in the first direction (when the first swing arm 21 rotates through the first support shaft 211, it drives the first swing arm 21 to rotate axially around the first support shaft 211). That is to say, the handle sleeve 32 drives the first swing arm 21 to swing in the second direction. At this time, since the length direction of the second avoidance hole 222 is the second direction, the handle sleeve 32 swings in the second avoidance hole 222, and the second swing arm 22 does not move. Similarly, when the handle sleeve 32 swings in the second direction, it drives the second swing arm 22 to rotate in the second direction (when the second swing arm 22 rotates through the second support shaft 221, it drives the second swing arm 22 to rotate axially around the second support shaft 221). That is to say, the handle sleeve 32 drives the second swing arm 22 to swing in the first direction. At this time, since the length direction of the first avoidance hole 212 is the first direction, the handle sleeve 32 swings in the first avoidance hole 212, and the first swing arm 21 does not move.

[0088] After the handle sleeve 32 and the central shaft 31 swing, the elastic member 33 is used to assist in resetting. The elastic member 33 is preferably a spring. Of course, the elastic member 33 can also be other reset structures with elastic reset ability.

[0089] In one embodiment, the implementation method of restricting the lower part of the handle sleeve 32 below the first swing arm 21 can be the prior art or can adopt the following design:

[0090] Refer to Figure 3 and Figure 4 , the inner diameter of the first avoidance hole 212 in the second direction on the first swing arm 21 is smaller than the outer diameter of the lower part of the handle sleeve 32, so that the lower part of the handle sleeve 32 cannot pass through the first avoidance hole 212.

[0091] In one embodiment, the bottom end of the central shaft 31 is an arc structure to reduce the swing resistance of the central shaft and the handle sleeve.

[0092] In one embodiment, the handle sleeve 32 is rotatably connected to the second swing arm 22 in the first direction and can drive the second swing arm 22 to press down. The pressing-down direction is the third direction, and the third direction is perpendicular to the first direction and the second direction respectively. As Figure 5 shown, the third direction is the Z-axis direction.

[0093] Refer to Figures 4 to 14 , one end of the second swing arm 22 in the second direction has a second support shaft 221. A pressing member 51 is provided at the bottom end of the second support shaft 221. A switch member 52 is provided on the base 12 below the pressing member 51. The bottom end of the switch member 52 is connected to the internal circuit of the base inside the base 12, or the switch member 52 directly passes through the base 12 and is connected to the external circuit provided below the base 12 to achieve power-on.

[0094] When the present invention starts to be used, press the handle sleeve 32. When the handle sleeve 32 is pressed down, it drives the second swing arm 22 and the crimping member 51 to press down. The crimping member 51 presses the switch member 52, and the switch member 52 energizes and activates the internal circuit of the base or the external circuit, realizing the monitoring of the swinging position of the handle sleeve. After releasing the pressure on the handle sleeve 32, the handle sleeve 32 and the second swing arm 22 return to their original positions under the action of the elastic member 33.

[0095] Specifically, when implemented, a crimping member 51 is integrally formed at the bottom end of the second support shaft 221 away from the second capacitor structure 40b.

[0096] In one embodiment, the implementation method by which the handle sleeve 32 can drive the second swing arm 22 to press down can be the prior art or can adopt the following design:

[0097] There is a certain gap when the second swing arm 22 is rotatably connected to the main housing. For example, as Figure 4 shown, when the second swing arm 22 is rotatably connected to the second support plate 122 through the second support shaft 221, there can be a preset distance between the bottom end of the second support shaft 221 and the bottom end of the shaft hole / openings on the second support plate 122, so that the handle sleeve 32 can drive the second swing arm 22 to press down until the bottom end of the second support shaft 221 abuts against and can rotate with the bottom end of the shaft hole / openings on the second support plate 122. At this time, the crimping member 51 presses the switch member 52.

[0098] In one embodiment, referring to Figures 1 to 4 , the switch member 52 is located outside the hollow cavity. At this time, the second support shaft 221 extends out of the hollow cavity.

[0099] Of course, the switch member 52 can also be designed to be located inside, and at this time the second support shaft 221 does not need to extend out of the hollow cavity.

[0100] In one embodiment, referring to Figure 3 and Figure 6 , both ends of the handle sleeve 32 in the first direction are respectively provided with handle sleeve support shafts 321. The handle sleeve 32 is pin-connected to the handle sleeve connection holes 223 on the second swing arm 22 through the handle sleeve support shafts 321.

[0101] The above connection method enables the handle sleeve 32 to drive the first swing arm 21 to swing in the second direction, and the handle sleeve 32 to perform a synchronous rotation action around the axis of the handle sleeve support shaft 321, without affecting the swinging action of the handle sleeve 32.

[0102] The preferred embodiments of the present invention have been described in detail above. However, it should be understood that after reading the above teachings of the present invention, those skilled in the art can make various changes or modifications to the present invention. These equivalent forms also fall within the scope defined by the appended claims of this application.
