[0055] Throughout this specification, references to "an embodiment" or "an embodiment" indicate that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Therefore, the appearance of "in an embodiment" or "an embodiment" in various places throughout the specification does not necessarily refer to the same embodiment. Furthermore, a particular feature, structure, or characteristic may be combined in any manner in one or more embodiments.

[0056] In the following description, in order to clearly demonstrate the structure and working method of this utility model, a number of directional terms will be used. However, terms such as "front", "back", "left", "right", "outside", "inside", "outward", "inward", "up", and "down" should be understood as convenient terms and not as limiting terms.

[0057] Reference Figures 1 to 14 This utility model provides a capacitive rocker device, including a main housing, a swing arm assembly, a rocker assembly, and a position monitoring assembly. The main housing includes an outer shell 11 and a base 12. 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 element 33. The position monitoring assembly includes two sets of capacitor structures, namely a first capacitor structure 40a and a second capacitor structure 40b. Specifically, each capacitor structure 40b includes a movable plate and two electrode plates.

[0058] The outer shell 11 and the base 12 are connected to form a hollow cavity. A large inner and outer shell clearance opening can be provided on the top surface of the outer shell 11 to facilitate the rocker arm assembly to extend out of the outer shell 11 and swing in the first or second direction.

[0059] The first swing arm 21 is disposed within the hollow cavity and rotatably connected to the main housing about a first direction. The first swing arm 21 can be rotatably connected to the outer shell 11, and also rotatably connected to two first support plates 121 disposed on the base 12 along the first direction. The first direction is... Figure 5 The X-axis direction in the diagram.

[0060] The second swing arm 22 is disposed within the hollow cavity and rotatably connected to the main housing about a second direction. The second swing arm 22 can be rotatably connected to the outer shell 11, and also rotatably connected to two second support plates 122 disposed on the base 12 along the second direction. The second direction is... Figure 5 The Y-axis direction is defined, and the second direction is perpendicular to the first direction.

[0061] The rocker assembly is located in the hollow cavity and its bottom end abuts against the bottom end of the main housing. Its 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 rocker assembly drives the first swing arm 21 and the second swing arm 22 to swing around the first direction and the second direction.

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

[0063] The movable plate 41a is fixedly connected to the first swing arm 21. After the two electrode plates 42a are energized, they form a first inductive capacitor structure. When the rocker assembly drives the first swing arm 21 to swing around the first direction, the movable plate 41a will cause the capacitance value of the first inductive capacitor structure to change as the rocker assembly carries the first swing arm 21 to rotate. Based on this change, the swing position of the rocker assembly around the first direction can be monitored.

[0064] The movable plate 41b is fixedly connected to the second swing arm 22. After the two electrode plates 42b are energized, they form a second sensing capacitor structure. When the rocker assembly drives the second swing arm 22 to swing around the second direction, the movable plate 41b will cause the capacitance value of the second sensing capacitor structure to change as the rocker assembly carries the second swing arm 22 to rotate. Based on 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 a center hole.

[0066] Reference Figure 3 , Figures 7 to 10 The first capacitor structure 40a is located on the side of one end of the first swing arm 21 in the first direction. The first end of the first swing arm 21 in the first direction has a first support shaft 211. The first support shaft 211 passes through the center hole of the electrode plate in the first capacitor structure 40a and is fixedly connected to the movable piece 41a in the first capacitor structure 40a. After the two electrode plates 42a in the first capacitor structure 40a are energized, when the rocker assembly drives the first swing arm 21 and the movable piece 41a in the first capacitor structure 40a to swing around the first direction, the capacitance value of the inductive capacitor formed by the two electrode plates 42a in the first capacitor structure 40a changes. The swing position of the rocker assembly around the first direction is monitored according to the change in capacitance value.

[0067] Reference Figure 4 , Figures 7 to 14 The second capacitor structure 40b is located on the side of one end of the second swing arm 22 in the second direction. The second end of the second swing arm 22 in the second direction has a second support shaft 221. The second support shaft 221 passes through the center hole of the electrode plate in the second capacitor structure 40b and is fixedly connected to the movable piece 41b in the second capacitor structure 40b. After the two electrode plates 42b in the second capacitor structure 40b are energized, when the rocker assembly drives the second swing arm 22 and the movable piece 41b in the second capacitor structure 40b to swing around the second direction, the capacitance value of the inductive capacitor formed by the two electrode plates 42b in the second capacitor structure 40b changes. The swing position of the rocker assembly around the second direction is monitored according to the change in capacitance value.

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

[0069] In practice, the movable piece can be a wedge-shaped structure with a thickness that gradually increases from one end to the other.

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

[0071] In one embodiment, reference is made to Figures 7 to 14 Each electrode plate has a power-on pin 421 at its bottom. The power-on pin 421 is connected to the internal wiring of the base 12 or directly passes through the base 12 and is connected to the external wiring located below the base 12.

[0072] The base's internal or external wiring supplies power to the electrode plates via the power pin 421.

[0073] In one embodiment, the capacitor structure further includes an outer shell and an inner shell. The outer shell, the inner shell, and the main shell are all detachably connected. The outer shell and the inner shell together form an internal cavity. The two electrode plates and the movable piece are located in the internal cavity. At least the inner shell is provided with a shell center hole.

[0074] Taking the first capacitor structure 40a as an example, refer to Figure 3 The first capacitor 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 detachably connected. The outer shell 43a and the inner shell 44a enclose an internal cavity. The two electrode plates 42a and the movable piece 41a are located in the internal cavity. At least the inner shell 44a is provided with a shell center hole.

[0075] Taking the second capacitor structure 40b as an example, refer to Figure 3 , Figure 11 and Figure 12 The second capacitor 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 detachably connected. The outer shell 43b and the inner shell 44b enclose an internal cavity. The two electrode plates 42b and the movable piece 41b are located in the internal cavity. At least the inner shell 44b is provided with a shell center hole.

[0076] The first support shaft 211 passes through the central hole of the housing and the central hole of the electrode plate in the first capacitor structure 40a in sequence, and is then fixedly connected to the movable piece 41a in the first capacitor structure 40a.

[0077] The second support shaft 221 passes through the central hole of the housing and the central hole of the electrode plate in the second capacitor structure 40b in sequence, and is then fixedly connected to the movable piece 41 in the second capacitor structure 40b.

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

[0079] In one embodiment, both the outer shell and the inner shell are engaged with the outer shell 11 via snap-fit ​​connections.

[0080] Taking the second capacitor structure 40b as an example, refer to Figure 11 and Figure 12 An outer snap fastener 431 is provided on the outer shell 43b, and the outer shell 43b is engaged with the outer shell 11 on the outside via the outer snap fastener 431. An inner snap fastener 441 is provided on the inner shell 44b, and the inner shell 44b is engaged with the outer shell 11 on the outside via the inner snap fastener 441.

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

[0082] In one embodiment, reference is made to Figure 3 , Figures 5 to 9 The first swing arm 21 has a first support shaft 211 at each end in the first direction, and the first swing arm 21 is connected to two first support plates 121 on the base 12 by the first support shaft 211 pin.

[0083] Reference Figures 4 to 9 The second swing arm 22 has a second support shaft 221 at each end in the second direction, and the second swing arm 22 is connected to the second support plate 122 on the base 12 by the second support shaft 221 pin.

[0084] In this embodiment, the pin connection is a shaft rotational connection within a hole. Specifically, the first support plate 121 and the second support plate 122 are respectively provided with shaft holes. These shaft holes can be closed holes or, as shown in the image, other types of holes. Figure 9 The top shown is an open opening. 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, the two are not fixedly connected, but rotatably connected.

[0085] In one embodiment, reference is made to Figure 6 The first swing arm 21 has a first clearance hole 212 for the rocker arm assembly to pass through, and the length direction of the first clearance hole 212 is a first direction. The second swing arm 22 has a second clearance hole 222 for the rocker arm assembly to pass through, and the length direction of the second clearance hole 222 is a second direction. The second swing arm 22 is located below the first swing arm 21.

[0086] Reference Figure 3 and Figure 5The bottom end of the central shaft 31 abuts against the center of the base 12. The handle sleeve 32 is fitted onto the upper outer side of the central shaft 31. The upper part of the handle sleeve 32 passes through the second clearance hole 222, the first clearance hole 212, and the outer shell 11 in sequence and extends out of the top of the outer shell 11. The lower part of the handle sleeve 32 is restricted below the first swing arm 21. The elastic element 33 is disposed between the central shaft 31 and the handle sleeve 32 and is fitted onto the outside of the central shaft 31.

[0087] When the handle sleeve 32 swings around the first direction, it causes the first swing arm 21 to rotate around the first direction (when the first swing arm 21 rotates through the first support shaft 211, it causes the first swing arm 21 to rotate around the first support shaft 211 axially). In other words, the handle sleeve 32 swings along the second direction with the first swing arm 21. Since the length direction of the second clearance hole 222 is the second direction, the handle sleeve 32 swings within the second clearance hole 222, and the second swing arm 22 does not move. Similarly, when the handle sleeve 32 swings around the second direction, it causes the second swing arm 22 to rotate around the second direction (when the second swing arm 22 rotates through the second support shaft 221, it causes the second swing arm 22 to rotate around the second support shaft 221 axially). In other words, the handle sleeve 32 swings along the first direction with the second swing arm 22. Since the length direction of the first clearance hole 212 is the first direction, the handle sleeve 32 swings within the first clearance 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 element 33 assists in resetting. The elastic element 33 is preferably a spring. Of course, the elastic element 33 can also be other reset structures with elastic reset capability.

[0089] In one embodiment, the lower part of the handle sleeve 32 being restricted below the first swing arm 21 can be implemented using existing technology, or it can adopt the following design:

[0090] Reference Figure 3 and Figure 4 The inner diameter of the first clearance hole 212 on the first swing arm 21 in the second direction 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 clearance 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 about a first direction and can press down with the second swing arm 22. The pressing direction is a third direction, which is perpendicular to both the first and second directions, such as... Figure 5 As shown, the third direction is the Z-axis direction.

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

[0094] When this utility model is first used, pressing the handle sleeve 32 causes the second swing arm 22 and the crimping member 51 to also press down. The crimping member 51 presses the switch member 52, which energizes the internal or external wiring of the base, thus activating the monitoring of the swing 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] In specific implementation, a press-fit component 51 is integrally formed at the bottom end of the second support shaft 221, which is far away from the second capacitor structure 40b.

[0096] In one embodiment, the method by which the handle sleeve 32 can press down with the second swing arm 22 can be based on existing technology, or it can adopt the following design:

[0097] The second swing arm 22 has a certain gap when it is rotatably connected to the main housing, for example... Figure 4 As shown, when the second swing arm 22 is rotatably connected to the second support plate 122 via the second support shaft 221, the bottom end of the second support shaft 221 and the bottom end of the shaft hole / opening on the second support plate 122 can have a preset distance, 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 the bottom end of the shaft hole / opening on the second support plate 122 and can rotate. At this time, the pressing member 51 presses the switch member 52.

[0098] In one embodiment, reference is made to Figures 1 to 4 The switch 52 is located outside the hollow cavity, and the second support shaft 221 extends out of the hollow cavity.

[0099] Of course, the switch 52 can also be designed to be located inside, in which case the second support shaft 221 does not need to extend out of the hollow cavity.

[0100] In one embodiment, reference is made to Figure 3 and Figure 6 The handle sleeve 32 has handle sleeve support shafts 321 at both ends in the first direction. The handle sleeve 32 is connected to the handle sleeve connection hole 223 pin on the second swing arm 22 through the handle sleeve support shafts 321.

[0101] The above connection method allows the handle sleeve 32 to swing along the second direction with the first swing arm 21, and the handle sleeve 32 to rotate synchronously around the axial direction of the handle sleeve support shaft 321 without affecting the swinging action of the handle sleeve 32.

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