Description

Technical Field

[0001] This utility model relates to the field of electrical switch technology, specifically to a bidirectional clutch mechanism for electrical switches and an electrical switch. Background Technology

[0002] Currently available switches are capable of electric closing and opening. Under the control of a controller, a motor drives the moving contact of the switch to move, thereby connecting or disconnecting the circuit and achieving automatic closing and opening. These switches typically also retain a mechanical manual closing and opening function, ensuring that operators can manually drive the moving contact to move and open the circuit in case of switch malfunctions.

[0003] With the increasing demands of power systems for line opening and closing control, electrical switches capable of electric opening and closing need to be able to perform both electric opening and closing, as well as manual opening and closing. However, the clutches on existing electrical switch operating mechanisms cannot achieve bidirectional automatic disengagement within a limited space.

[0004] In view of this, there is an urgent need to design a bidirectional clutch mechanism and an electrical switch for use in electrical switches. Summary of the Invention

[0005] To solve the above problems, this utility model provides a bidirectional clutch mechanism for electrical switches and an electrical switch.

[0006] In a first aspect, this utility model provides a bidirectional clutch mechanism for an electrical switch, comprising a base plate, an outer gear disk located on one side of the base plate, an inner gear ring movably connected to the outer gear disk, a locking disc fixedly connected to the outer periphery of the inner gear ring, and a clutch disc located on one side of the inner gear ring. The inner wall of the inner gear ring is provided with internal transmission teeth. A linkage chamber is formed between the outer gear disk and the clutch disc. A sun gear is provided on the side of the outer gear disk near the linkage chamber. An output shaft passes through the sun gear. The clutch disc is connected to the output shaft. Planetary gears are provided within the linkage chamber. The planetary gears mesh with the sun gear and the internal transmission teeth, respectively. The rotation shafts of the planetary gears are connected to the clutch disc. Locking components are provided on both sides of the inner gear ring. The locking components, through linkage with the clutch disc, restrict the inner gear ring from rotating in the opposite direction to the clutch disc, but do not restrict the inner gear ring from rotating in the same direction as the clutch disc.

[0007] The present invention is further configured such that the locking components on both sides are respectively a tripping locking component and a closing locking component. Each locking component includes a locking seat fixed on the base plate, a locking member movably connected in the locking seat, and a reset member connected to the locking member. The reset member provides radial and axial forces to the locking member on the output shaft. The locking member includes a pressing part and a non-returning part. The outer periphery of the clutch rotary table is provided with a driving part and a notch that are linked and cooperate with the same pressing part. The driving part is used to press the locking member down to the bottom of the clutch rotary table, and the notch is used to reset the locking member. The outer periphery of the locking rotary table is provided with a slot that is linked and cooperates with the non-returning part.

[0008] The present invention is further configured such that the driving part includes a guide slope, a pressing end face, and a limiting end face arranged in sequence; when the driving part acts on the pressing part, the guide slope drives the locking member to move towards the substrate; when the pressing end face acts on the pressing part, the locking member is located below the clutch turntable, and the limiting end face is directly opposite the pressing part to restrict the clutch turntable from continuing to rotate.

[0009] The present invention is further configured such that a reset end adapted to the notch is provided on the side of the pressing part near the clutch turntable. When the notch rotates with the clutch turntable to the position of the reset end, the reset end moves into the notch under the action of the reset member.

[0010] The present invention is further configured such that the anti-reverse part includes an unlocking end face and a locking end face; when the locking member is pressed down by the driving part, the anti-reverse part and the locking turntable are on the same working plane; when the locking member is not pressed down below the clutch turntable, the anti-reverse part and the locking turntable are not on the same working plane; the anti-reverse part of the opening locking assembly and the anti-reverse part of the closing locking assembly respectively restrict the rotation of the locking turntable in different directions.

[0011] The present invention is further configured such that a first positioning groove and a second positioning groove are respectively provided on the side and bottom of the locking member, and the reset member includes a first reset member and a second reset member. The first reset member and the second reset member are respectively connected in the first positioning groove and the second positioning groove. One end of the first reset member abuts against the locking member, and the other end of the first reset member abuts against the locking seat. One end of the second reset member abuts against the locking member, and the other end of the second reset member abuts against the substrate.

[0012] The present invention is further configured such that a blocking edge is provided between the drive unit and the notch in the same group; the drive unit is symmetrically arranged on the clutch rotary table, and the notch is symmetrically arranged on the clutch rotary table; the opening locking assembly and the closing locking assembly are symmetrically arranged on both sides of the clutch rotary table.

[0013] The present invention is further configured such that a through hole is provided at the center of the sun gear, a rotating hole is provided at the center of the clutch disc, and the output shaft includes, in sequence, an operating part, a rotating shaft part, and a snap-fit ​​part, wherein the rotating shaft part is connected in the through hole and the snap-fit ​​part is connected in the rotating hole.

[0014] The present invention is further configured such that a planetary guide groove is provided inside the external gear disk, and the rotating shaft of the planetary gear is connected in the planetary guide groove.

[0015] In a second aspect, an electrical switch is provided, including the aforementioned bidirectional clutch mechanism for an electrical switch.

[0016] The operating principle of the bidirectional clutch mechanism for electrical switches in this technical solution is as follows: When the bidirectional clutch mechanism performs electric closing or electric opening, the internal motor of the electrical switch drives the external gear disc to rotate clockwise or counterclockwise through the transmission mechanism. The sun gear rotates synchronously. The locking engagement between the locking disc and the locking component prevents the internal gear ring from rotating. The sun gear drives the planetary gears to rotate around the sun gear. The clutch disc rotates with the planetary gears, thereby driving the output shaft to rotate and completing the electric closing or electric opening action. When the bidirectional clutch mechanism performs manual closing or manual opening, the output shaft is manually rotated clockwise or counterclockwise. The output shaft drives the clutch disc to rotate. The locking component does not lock the locking disc, allowing the internal gear ring to rotate during manual operation. The planetary gears rotate around the sun gear with the clutch disc and also rotate on their own axis. The internal gear ring rotates with the planetary gears, while the sun gear remains stationary due to the resistance of the transmission mechanism and the motor.

[0017] This utility model provides a bidirectional clutch mechanism for electrical switches that supports both electric and manual closing and opening operations within a limited space. This meets the ever-increasing demands of power systems for line opening and closing control, enhancing the flexibility and adaptability of electrical switch operation. The planetary gears mesh with the transmission internal teeth on the inner wall of the sun gear and the internal gear ring, respectively. This transmission method has the advantages of accurate transmission ratio, high load-bearing capacity, and stable operation. During electric and manual operation, the meshing relationship between the gears can accurately transmit power and motion, reducing energy loss and transmission errors, further improving the accuracy and reliability of electrical switch opening and closing operations.

[0018] This invention, through locking components located on both sides of the internal gear ring, and their linkage with the clutch disc, precisely restricts the internal gear ring from rotating in the opposite direction relative to the clutch disc, while not restricting its rotation in the same direction. This design ensures that during electric operation, the internal gear ring is reliably locked, allowing power to be stably transmitted to the output shaft for accurate engagement or disengagement. During manual operation, the internal gear ring can rotate freely, while maintaining stable motion between the planetary gears and the sun gear, preventing motion interference or malfunctions, and improving the operational stability and reliability of the entire bidirectional clutch mechanism.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] Example 1

[0037] Combined with appendix Figure 1 To be continued Figure 16 This utility model provides a bidirectional clutch mechanism for an electrical switch, comprising a base plate 1, an outer gear disk 2 located on one side of the base plate 1, an inner gear ring 3 movably connected to the outer gear disk 2, a locking turntable 4 fixedly connected to the outer periphery of the inner gear ring 3, and a clutch turntable 5 located on one side of the inner gear ring 3. The inner wall of the inner gear ring 3 is provided with internal transmission teeth 31. A linkage chamber 32 is formed between the outer gear disk 3 and the clutch turntable 5. A sun gear 21 is located on the side of the outer gear disk 2 closest to the linkage chamber 32, and an output shaft 6 passes through the sun gear 21. The clutch disc 5 is connected to the output shaft 6. The linkage chamber 32 is provided with planetary gears 33, which mesh with the sun gear 21 and the transmission internal gear 31 respectively. The rotating shaft 331 of the planetary gears 33 is connected to the clutch disc 5. Locking components (opening locking component 7 and closing locking component 8) are provided on both sides of the internal gear ring 3. The locking components restrict the internal gear ring 3 from rotating in the opposite direction to the rotation of the clutch disc 5 through linkage with the clutch disc 5, but do not restrict the internal gear ring 3 from rotating in the same direction as the rotation of the clutch disc 5.

[0038] In this embodiment, the output shaft 6 is a control component that controls the opening and closing of the electrical switch. The clutch turntable 5 rotates synchronously with the output shaft 6. The planetary gear 33 is encapsulated in the linkage chamber 32. The planetary gear 33 revolves around the sun gear 21 as the clutch turntable 5 rotates. The sun gear 21 is integrally formed on the external gear disk 2.

[0039] In this embodiment, under electric drive (external motor drives the external gear disk to rotate), the locking components on both sides restrict the rotation of the locking turntable 4, thereby restricting the internal gear ring 3 from rotating in the opposite direction to the clutch turntable 5. That is, under electric drive, the internal gear ring 3 remains relatively stationary relative to the base plate 1. Under manual drive (manual rotation of the output shaft), the locking components on both sides do not restrict the rotation of the locking turntable 4, thereby not restricting the internal gear ring 3 from rotating in the same direction as the clutch turntable 5. The internal gear ring 3 rotates relative to the base plate 1.

[0040] In this embodiment, when the bidirectional clutch mechanism performs electric closing or electric opening, the internal motor of the electrical switch drives the external gear disk 2 to rotate clockwise or counterclockwise through the transmission mechanism. The sun gear 21 rotates synchronously. The locking engagement between the locking disc 4 and the opening locking component 7 / closing locking component 8 prevents the internal gear ring 3 from rotating. The sun gear 21 drives the planetary gears 33 to rotate around the sun gear 21. The clutch disc 5 rotates with the planetary gears 33, thereby driving the output shaft 6 to rotate, completing the electric closing or electric opening action. When the bidirectional clutch mechanism is manually closed or opened, the output shaft 6 is rotated clockwise or counterclockwise. The output shaft 6 drives the clutch disc 5 to rotate. Neither the opening locking component 7 nor the closing locking component 8 locks the disc 4, allowing the internal gear ring 3 to rotate manually. The planetary gear 33 rotates around the sun gear 21 with the clutch disc 5 and also rotates on its own axis. The internal gear ring 3 rotates with the planetary gear 33, while the sun gear 21 remains stationary due to the resistance of the transmission mechanism and the motor. The specific actions of electric and manual closing and opening are described in detail below.

[0041] In this embodiment, as shown in the appendix Figure 9 To be continued Figure 16As shown, the locking components on both sides are the opening locking component 7 and the closing locking component 8, respectively. The opening locking component 7 includes an opening locking seat 71 fixed on the base plate 1, an opening locking member 72 movably connected in the opening locking seat 71, and an opening reset member connected to the opening locking member 72. The opening reset member provides radial and axial forces to the opening locking member 72 on the output shaft 6. The opening locking member 72 includes an opening pressing part 721 and an opening anti-reverse part 722. The outer periphery of the clutch rotary table 5 is provided with an opening driving part 51 and an opening notch 52 that are linked and cooperate with the opening pressing part 721. The opening driving part 51 is used to press the opening locking member 72 down to the bottom of the clutch rotary table 5, and the opening notch 52 is used to reset the opening locking member 72. The closing locking component 8 includes a closing locking seat 81 fixed on the base plate 1 and a closing locking member movably connected in the closing locking seat 81. The clutch lever 82 and the closing reset member connected to the closing locking member 82, wherein the closing reset member provides radial and axial forces to the closing locking member 82 on the output shaft 6, the closing locking member 82 includes a closing pressing part 821 and a closing anti-reverse part 822; the outer periphery of the clutch lever 5 is respectively provided with a closing driving part 53 and a closing notch 54 that are linked and cooperate with the closing pressing part 821, the closing driving part 53 is used to press the closing locking member 82 down to the clutch lever 6. Below the closing turntable 5, the closing notch 54 is used for resetting the closing locking member 82; the outer periphery of the locking turntable 4 is provided with a slot 41 that is linked with the opening anti-reverse part 722 and the closing anti-reverse part 822. When the opening locking member 72 / closing locking member 82 is pressed down to the bottom of the clutch turntable 5, the opening anti-reverse part 722 / closing anti-reverse part 822 will be in the same working plane with the locking turntable 4 to form a linkage.

[0042] In this embodiment, as shown in the appendix Figure 3 As shown, the tripping drive unit 51 includes a tripping guide slope 511, a tripping pressing end face 512, and a tripping limiting end face 513 arranged sequentially. When the tripping drive unit 51 just acts on the tripping pressing part 721, the tripping guide slope 511 drives the tripping locking member 72 to move towards the base plate 1. When the tripping pressing end face 512 fully acts on the tripping pressing part 721, the tripping locking member 72 is located below the clutch rotary table 5, and the tripping limiting end face 513 faces the tripping pressing part 721 to restrict the clutch rotary table 5 from continuing to rotate.

[0043] In this embodiment, as shown in the appendix Figure 3As shown, the closing drive unit 53 includes a closing guide slope 531, a closing pressing end face 532, and a closing limiting end face 533 arranged sequentially. When the closing drive unit 53 just acts on the closing pressing part 821, the closing guide slope 531 drives the closing locking member 82 to move towards the base plate 1. When the closing pressing end face 532 fully acts on the closing pressing part 821, the closing locking member 82 is located below the clutch rotary table 5, and the closing limiting end face 533 faces the closing pressing part 821 to restrict the clutch rotary table 5 from continuing to rotate.

[0044] In this embodiment, as shown in the appendix Figure 3 and attached Figure 7 As shown, the tripping pressing part 721 is provided with a tripping reset end 723 adapted to the tripping notch 52 on the side near the clutch rotary table 5. When the tripping notch 52 rotates with the clutch rotary table 5 to the position of the tripping reset end 723, the tripping reset end 723 moves into the tripping notch 52 under the action of the tripping reset member, thereby resetting the tripping locking member 72 from below the clutch rotary table 5 to the side of the clutch rotary table 5.

[0045] In this embodiment, as shown in the appendix Figure 3 and attached Figure 8 As shown, the closing pressing part 821 is provided with a closing reset end 823 on the side near the clutch rotary table 5, which is adapted to the closing notch 54. When the closing notch 54 rotates with the clutch rotary table 5 to the position of the closing reset end 823, the closing reset end 823 moves into the closing notch 54 under the action of the closing reset member, thereby resetting the closing locking member 82 from below the clutch rotary table 5 to the side of the clutch rotary table 5.

[0046] In this embodiment, as shown in the appendix Figure 7 and attached Figure 8As shown, the tripping anti-reverse part 722 includes a tripping unlocking end face 724 and a tripping locking end face 725; when the tripping locking member 72 is pressed down by the tripping drive part 51, the tripping anti-reverse part 722 and the locking rotary table 4 are on the same working plane; when the tripping locking member 72 is not pressed down below the clutch rotary table 5, the tripping anti-reverse part 722 and the locking rotary table 4 are not on the same working plane; the closing anti-reverse part 822 includes a closing unlocking end face 824 and a closing locking end face 825. End face 825; when the closing locking member 82 is pressed down by the closing drive part 53, the closing anti-reverse part 822 and the locking turntable 4 are on the same working plane; when the closing locking member 82 is not pressed down below the clutch turntable 5, the closing anti-reverse part 822 and the locking turntable 4 are not on the same working plane; the opening anti-reverse part 722 of the opening locking assembly 7 and the closing anti-reverse part 822 of the closing locking assembly 8 respectively restrict the rotation of the locking turntable 4 in different directions.

[0047] In this embodiment, when the slot 41 of the locking turntable 4 acts on the opening unlocking end face 724 or the closing unlocking end face 824, the locking turntable 4 can rotate; when the slot 41 of the locking turntable 4 acts on the opening locking end face 725 or the closing locking end face 825, the locking turntable 4 cannot rotate.

[0048] In this embodiment, as shown in the appendix Figure 9 To be continued Figure 12 As shown, the side and bottom of the trip locking member 72 are respectively provided with a first trip positioning groove 726 and a second trip positioning groove 727.

One end of the first trip reset member 73 abuts against the trip locking member 72, and the other end of the first trip reset member 73 abuts against the trip locking seat 71. One end of the second trip reset member 74 abuts against the trip locking member 72, and the other end of the second trip reset member 74 abuts against the base plate 1. In another embodiment, the trip reset member can also be set as an inclined reset member, which can provide radial and axial forces to the output shaft 6 for the trip locking member 72.

[0049] In this embodiment, as shown in the appendix Figure 13 To be continued Figure 16As shown, the closing locking member 82 has a first closing positioning groove 826 and a second closing positioning groove 827 respectively on its side and bottom. The closing reset member includes a first closing reset member 83 and a second closing reset member 84. The first closing reset member 83 and the second closing reset member 84 are respectively connected in the first closing positioning groove 826 and the second closing positioning groove 827. One end of the first closing reset member 83 abuts against the closing locking member 82, and the other end of the first closing reset member 83 abuts against the closing locking seat 81. One end of the second closing reset member 84 abuts against the closing locking member 82, and the other end of the second closing reset member 84 abuts against the base plate 1. In another embodiment, the closing reset member can also be configured as an inclined reset member, which can provide radial and axial forces to the output shaft 6 for the closing locking member 82.

[0050] In this embodiment, as shown in the appendix Figure 3 As shown, a blocking edge is provided between the drive unit and the notch in the same group; a blocking blocking edge 55 is provided between the tripping drive unit 51 and the tripping notch 52, and a closing blocking edge 56 is provided between the closing drive unit 52 and the closing notch 54; the tripping drive unit 51 and the closing drive unit 53 are symmetrically arranged on the clutch rotary table 5, and the tripping notch 52 and the closing notch 54 are symmetrically arranged on the clutch rotary table 5; the tripping locking assembly 7 and the closing locking assembly 8 are symmetrically arranged on both sides of the clutch rotary table 5.

[0051] In this embodiment, the tripping pressing part 721 abuts against the tripping blocking edge 55 under the action of the tripping first reset member 73 until the tripping reset end 723 rotates to the tripping notch 52; the closing pressing part 821 abuts against the closing blocking edge 56 under the action of the closing first reset member 83 until the closing reset end 823 rotates to the closing notch 54.

The rotating shaft part 62 is connected in the through hole 22, and the snap-fit ​​part 63 is connected in the rotating hole 57.

[0053] In this embodiment, as shown in the appendix Figure 5 As shown, the outer gear disk 2 has a planetary guide groove 23 inside, and the rotating shaft 331 of the planetary gear 33 is connected in the planetary guide groove 23, so that the planetary gear 33 can revolve stably around the sun gear 21.

[0054] The following will be combined with the appendix Figure 9 To be continued Figure 16 This section details the operating principle of a bidirectional clutch mechanism used in electrical switches, enabling closing and opening in both electric and manual modes.

[0055] First, the structure of the bidirectional clutch assembly of the electrical switch in both the open and closed states is described:

[0056] As attached Figure 9 To be continued Figure 12 As shown, when the electrical switch is in the open state, the open drive part 51 on the clutch rotary table 5 presses the open locking member 72 to the bottom of the clutch rotary table 5, the open second reset member 74 is compressed, the open anti-reverse part 722 of the open locking member 72 is on the same working plane as the locking rotary table 4, and under the action of the open first reset member 73, the open anti-reverse part 722 abuts against the slot 41 of the locking rotary table 4. Under the action of the close first reset member 83 and the close second reset member 84, the close locking member 82 abuts against the close notch 54 of the clutch rotary table 5. The close pressing part 821 is on the same working plane as the clutch rotary table 5, and the close anti-reverse part 822 is not on the same working plane as the locking rotary table 4.

[0057] As attached Figure 13 To be continued Figure 16 As shown, when the electrical switch is in the closed state, the closing drive part 53 on the clutch rotary table 5 presses the closing locking member 82 to the bottom of the clutch rotary table 5, the closing second reset member 84 is compressed, the closing anti-reverse part 822 of the closing locking member 82 is on the same working plane as the locking rotary table 4, and under the action of the closing first reset member 83, the closing anti-reverse part 822 abuts against the slot part 41 of the locking rotary table 4. Under the action of the opening first reset member 73 and the opening second reset member 74, the opening locking member 72 abuts against the opening notch 52 of the clutch rotary table 5. The opening pressing part 721 is on the same working plane as the clutch rotary table 5, and the opening anti-reverse part 722 is not on the same working plane as the locking rotary table 4.

[0058] The following describes the operating principle of the electric switch for electric closing: The motor drives the external gear disk 2 to rotate forward through the transmission mechanism, and the sun gear 21 rotates synchronously forward. The sun gear 21 drives the planetary gears 33 to rotate, but the slot 41 of the locking disc 4 and the opening locking end face 725 of the opening locking member 72 form a locking engagement, preventing the locking disc 4 from rotating forward, thus keeping the internal gear ring 3 stationary. While rotating on its own axis, the planetary gears 33 revolve forward around the sun gear 21 inside the linkage chamber 32, thereby driving the clutch disc 5 to rotate forward. When the clutch rotary table 5 rotates in the forward direction, the output shaft 6 rotates with the clutch rotary table 5 to perform electric closing. During the electric closing process of the electrical switch, the closing drive part 53 of the clutch rotary table 5 presses the closing locking member 82 to the bottom of the clutch rotary table 5, and the opening notch 52 of the clutch rotary table 5 rotates to the position of the opening reset end 723. The opening locking member 72 rises under the action of the second opening reset member 74, so that the opening anti-reverse part 722 and the locking rotary table 4 are not on the same working plane. After the electrical switch completes closing, the bidirectional clutch assembly is in the state described above.

[0059] The following describes the operating principle of the electric switch's electric tripping: The motor drives the external gear disk 2 to rotate in the opposite direction via a transmission mechanism. The sun gear 21 rotates synchronously in the opposite direction, and the sun gear 21 drives the planetary gears 33 to rotate. However, the slot 41 of the locking disc 4 and the closing locking end face 825 of the closing locking member 82 form a locking engagement, preventing the locking disc 4 from rotating in the opposite direction. This keeps the internal gear ring 3 stationary. While rotating, the planetary gears 33 revolve in the opposite direction around the sun gear 21 inside the linkage chamber 32, thereby driving the clutch disc 5 to rotate in the opposite direction. When the electrical switch is electrically opened, the output shaft 6 rotates in the opposite direction with the clutch rotary table 5 to perform electric opening. During the electric opening process of the electrical switch, the opening drive part 51 of the clutch rotary table 5 presses the opening locking member 72 to the bottom of the clutch rotary table 5, and the closing notch 54 of the clutch rotary table 5 rotates to the position of the closing reset end 823. The closing locking member 82 rises under the action of the closing second reset member 84, so that the closing anti-reverse part 822 and the locking rotary table 4 are not on the same working plane. When the electrical switch completes the opening, the bidirectional clutch assembly is in the state described above.

[0060] The following describes the operating principle of the electrical switch when manually closing: Manually rotating the output shaft 6 forward causes the clutch disc 5 to rotate forward. The planetary gear 33 revolves forward around the sun gear 21 inside the linkage chamber 32. Since the sun gear 21 and the external gear disc 2 cannot rotate due to motor resistance, the planetary gear 33 rotates forward while revolving. The slot 41 of the locking disc 4 does not form a locking engagement with the open / unlock end face 724, causing the internal gear ring 3 to rotate forward with the planetary gear 33. The locking disc 4 acts on the open / unlock end face 724, and the open / unlock... The fixed part 72 is compressed into the inside of the trip locking seat 71, and the trip first reset part 73 is compressed, thereby performing manual closing; during the manual closing process of the electrical switch, the closing drive part 53 of the clutch rotary table 5 presses the closing locking part 82 to the bottom of the clutch rotary table 5, the trip notch 52 of the clutch rotary table 5 rotates to the position of the trip reset end 723, and the trip locking part 72 rises under the action of the trip second reset part 74, so that the trip anti-reverse part 722 and the locking rotary table 4 are not on the same working plane. When the electrical switch is closed, the bidirectional clutch assembly is in the state described above.

[0061] The following describes the operating principle of the electrical switch for manual tripping: Manually rotating the output shaft 6 in the reverse direction causes the clutch disc 5 to rotate in the opposite direction. The planetary gear 33 revolves in the opposite direction around the sun gear 21 inside the linkage chamber 32. Since the sun gear 21 and the external gear disc 2 cannot rotate due to motor resistance, the planetary gear 33 rotates in the opposite direction while revolving. The slot 41 of the locking disc 4 does not form a locking engagement with the closing / unlocking end face 824, causing the internal gear ring 3 to rotate in the opposite direction with the planetary gear 33. The locking disc 4 acts on the closing / unlocking end face 824, and the closing lock... The fixed part 82 is compressed into the closing locking seat 81, and the first closing reset part 83 is compressed, thereby performing manual closing; during the manual opening of the electrical switch, the opening drive part 51 of the clutch rotary table 5 presses the opening locking part 72 to the bottom of the clutch rotary table 5, the closing notch 54 of the clutch rotary table 5 rotates to the position of the closing reset end 823, and the closing locking part 82 rises under the action of the second closing reset part 84, so that the closing anti-reverse part 822 and the locking rotary table 4 are not on the same working plane. When the electrical switch is closed, the bidirectional clutch assembly is in the state described above.

[0062] In this embodiment, the bidirectional clutch mechanism for the electrical switch can support both electric closing and opening of the electrical switch and manual closing and opening operations within a limited space, meeting the ever-increasing requirements of the power system for line opening and closing control and improving the flexibility and adaptability of electrical switch operation. The planetary gears mesh with the transmission internal teeth on the inner wall of the sun gear and the internal gear ring, respectively. This transmission method has the advantages of accurate transmission ratio, large load capacity, and stable operation. During electric and manual operation, the meshing relationship between the gears can accurately transmit power and motion, reduce energy loss and transmission error, and further improve the accuracy and reliability of the electrical switch opening and closing operation.

[0063] This invention, through locking components located on both sides of the internal gear ring, and their linkage with the clutch disc, precisely restricts the internal gear ring from rotating in the opposite direction relative to the clutch disc, while not restricting its rotation in the same direction. This design ensures that during electric operation, the internal gear ring is reliably locked, allowing power to be stably transmitted to the output shaft for accurate engagement or disengagement. During manual operation, the internal gear ring can rotate freely, while maintaining stable motion between the planetary gears and the sun gear, preventing motion interference or malfunctions, and improving the operational stability and reliability of the entire bidirectional clutch mechanism.
