Description

Technical Field

[0001] This invention relates to the field of technology, particularly to the field of low-voltage electrical appliances, and especially to an electric operating module and circuit breaker. Background Technology

[0002] In the field of low-voltage electrical appliances, the electric operating module of a circuit breaker is used to realize the electric closing and opening operations of the circuit breaker. In the prior art, the electric operating module usually adopts a gear set scheme. The gear set occupies a large amount of planar space, and the motor needs to repeatedly switch directions to achieve the closing and opening operations. Repeated switching of motor direction leads to complex control logic, reduced motor life, and the gear set scheme has the problem of stalling at extreme positions, affecting the reliability and service life of the electric operating module. Summary of the Invention

[0003] The purpose of this invention is to provide an electric operating module and circuit breaker to solve the technical problems in the prior art where the motor needs to repeatedly switch directions and there is stalling at extreme positions.

[0004] In a first aspect, the present invention provides an electric operating module for a circuit breaker, the electric operating module comprising: a housing and an output component, a handle, a drive mechanism and a clutch structure disposed within the housing; The output component is drively connected to the handle and the drive mechanism; The clutch mechanism is used to move the output component along the axial direction of the handle; During the closing process, the clutch structure connects the output component and the handle through a transmission connection, so that the output component drives the handle to rotate to the closing position; After the handle is rotated to the closed position, the clutch structure disconnects the transmission connection between the output component and the handle, so that the output component can continue to rotate relative to the handle.

[0005] In an optional embodiment, along the axial direction of rotation of the handle, a first transmission boss is provided at the end of the handle facing the output member, and a second transmission boss is provided at the end of the output member facing the handle. When the clutch structure causes the output component to move toward the handle, the second transmission boss enters the rotation path of the first transmission boss to connect the transmission connection between the output component and the handle. When the clutch structure causes the output component to move away from the handle, the second transmission boss exits the rotation path of the first transmission boss to disconnect the transmission connection between the output component and the handle.

[0006] In an optional embodiment, the clutch structure includes a drive ramp and a drive boss; The driving ramp is disposed on the housing, and the driving boss is disposed on the radial sidewall of the output component; or, the driving ramp is disposed on the radial sidewall of the output component, and the driving boss is disposed on the housing. After the handle is rotated to the closed position, the drive mechanism continues to drive the output component to rotate, and the drive boss moves along the drive inclined surface so that the second transmission boss exits the rotation path of the first transmission boss.

[0007] In an optional embodiment, the clutch structure includes a drive spring; The drive spring is disposed between the output member and the drive mechanism to provide a force for the output member to move toward the handle, so that the second transmission boss enters the rotation path of the first transmission boss.

[0008] In an optional embodiment, the first transmission boss includes opposing first and second sides along the circumference of the handle, and the second transmission boss includes opposing third and fourth sides along the circumference of the handle. When the second transmission boss is located within the rotation path of the first transmission boss, the first side is opposite to the third side, and the second side is opposite to the fourth side. Along the axial direction of the handle, at least one of the first side, the second side, the third side, and the fourth side is provided with a guide ramp.

[0009] In an optional embodiment, a free position detection switch disposed within the housing is also included; The second transmission boss is used to trigger the free position detection switch when the output member is in the free position.

[0010] In an optional embodiment, the radial sidewall of the handle is provided with a handle radial boss; The electric operating module also includes a trip position detection switch disposed within the housing, and the radial boss of the handle is used to trigger the trip position detection switch when the handle is in the trip position; and / or; The electric operating module also includes a closing position detection switch disposed within the housing, and the radial boss of the handle is used to trigger the closing position detection switch when the handle is in the closing position.

[0011] In an optional embodiment, a locking position detection switch, a linkage component, and a locking component are also provided within the housing; Both the linkage and the locking member are rotatably mounted on the housing. Both the linkage and the locking member have an active arm and a driven arm relative to their own rotation center, and the active arm of the locking member is located on the rotation path of the driven arm of the linkage. The radial sidewall of the output component is provided with an output component radial boss. The output component radial boss is used to drive the active arm of the linkage component to rotate when the output component switches from the free position to the locked position by rotation, so that the driven arm of the linkage component drives the active arm of the locking component to rotate and triggers the locking position detection switch.

[0012] In an optional embodiment, a reset member disposed on the housing is further included, the reset member being connected to the driven arm of the locking member; and / or; It also includes a limiting part disposed on the housing, the limiting part being located on the side of the driven arm of the linkage member away from the driving arm of the locking member, for limiting the rotation angle of the driven arm of the linkage member.

[0013] Secondly, the present invention provides a circuit breaker including the electrically operated module described in any of the foregoing embodiments.

[0014] Compared with the prior art, the technical advantages of the electric operating module and circuit breaker provided by the present invention are as follows: The electric operating module provided by this invention includes: a housing, an output component, a handle, a drive mechanism, and a clutch structure; the output component is driveably connected to the handle and the drive mechanism; the clutch structure is used to move the output component along the axial direction of the handle; during the closing process, the clutch structure connects the drive connection between the output component and the handle, so that the output component drives the handle to rotate to the closing position; after the handle rotates to the closing position, the clutch structure disconnects the drive connection between the output component and the handle, so that the output component can continue to rotate relative to the handle.

[0015] During the closing process, the drive mechanism drives the output component to rotate. A clutch mechanism maintains the transmission connection between the output component and the handle during closing, allowing the output component to rotate the handle to the closing position. Once the handle reaches the closing position, the clutch mechanism disengages the transmission connection between the output component and the handle, allowing the output component to continue rotating relative to the handle. This eliminates the transmission connection between the output component and the handle after the circuit is fully closed, preventing the motor from stalling at its limit positions and improving the reliability of the electric operating module. Furthermore, the drive mechanism only needs to rotate in one direction throughout the entire closing process and after the circuit is fully closed, eliminating the need for repeated direction switching by the motor, simplifying the control logic and extending the motor's lifespan.

Therefore, the technical advantages and effects achieved by the circuit breaker include those achieved by the above-mentioned electric operating module, which will not be described in detail here.

[0025] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0026] The specific structure is as follows: Figures 1 to 8 As shown.

[0027] This embodiment provides an electrically operated module for a circuit breaker. The electrically operated module includes a housing 1 and an output component 2, a handle 3, a drive mechanism 4, and a clutch structure disposed within the housing 1. The output component 2 is drivenly connected to the handle 3 and the drive mechanism 4. During the closing process, the clutch structure connects the output component 2 and the handle 3, causing the output component 2 to drive the handle 3 to rotate to the closed position. After the handle 3 rotates to the closed position, the clutch structure disconnects the drive connection between the output component 2 and the handle 3, allowing the output component 2 to continue rotating relative to the handle 3. By connecting the output component 2 and the handle 3 during the closing process through the clutch structure, the output component 2 can drive the handle 3 to rotate to the closed position; when the handle 3 rotates to the closed position, the clutch structure disconnects the drive connection between the output component 2 and the handle 3, allowing the output component 2 to continue rotating relative to the handle 3. In this way, after the circuit breaker is fully closed, the output component 2 no longer maintains a drive connection with the handle 3, avoiding motor stalling at extreme positions and improving the reliability of the electrically operated module. Meanwhile, the drive mechanism 4 only needs to rotate in one direction during the entire closing process and after the closing is complete, eliminating the need for the motor to repeatedly switch directions, which simplifies the control logic and extends the motor's lifespan.

[0028] In this embodiment, the driving structure can be a gearbox, a gear assembly, or any other structure capable of driving the output component 2 to rotate, as long as it meets the requirements.

[0029] In this embodiment, along the axial direction of rotation of the handle 3, a first transmission boss 5 is provided at the end of the handle 3 facing the output component 2, and a second transmission boss 6 is provided at the end of the output component 2 facing the handle 3. A clutch mechanism is used to move the output component 2 along the axial direction of the handle 3. When the clutch mechanism moves the output component 2 toward the handle 3, the second transmission boss 6 enters the rotation path of the first transmission boss 5 to connect the transmission connection between the output component 2 and the handle 3. When the clutch mechanism moves the output component 2 away from the handle 3, the second transmission boss 6 exits the rotation path of the first transmission boss 5 to disconnect the transmission connection between the output component 2 and the handle 3. Through the cooperation of the first transmission boss 5 and the second transmission boss 6, the connection and disconnection of the transmission connection between the output component 2 and the handle 3 are achieved. The first transmission boss 5 and the second transmission boss 6 have simple structures, are easy to manufacture, and achieve clutch engagement through axial movement, ensuring reliable operation. This embodiment is not limited to this; the first transmission boss 5 can also be provided on the output component 2, and the second transmission boss 6 can also be provided on the handle 3, as long as the connection and disconnection of the transmission connection can be achieved through axial movement.

[0030] In this embodiment, the clutch structure includes a driving ramp 7 and a driving boss 8. The driving ramp 7 is disposed on the outer casing 1, and the driving boss 8 is disposed on the radial sidewall of the output component 2. Alternatively, the driving ramp 7 is disposed on the radial sidewall of the output component 2, and the driving boss 8 is disposed on the outer casing 1. After the handle 3 is rotated to the closed position, the drive mechanism 4 continues to drive the output component 2 to rotate, and the driving boss 8 moves along the driving ramp 7, so that the second transmission boss 6 exits the rotation path of the first transmission boss 5. Through the cooperation of the driving boss 8 and the driving ramp 7, the rotational motion of the output component 2 is converted into linear motion along the axial direction of the handle 3, so that after the clutch is closed, the second transmission boss 6 automatically exits the rotation path of the first transmission boss 5, realizing the disconnection of the transmission connection. This structure does not require an additional drive source, and the clutch can be engaged and disengaged solely by the continued rotation of the drive mechanism 4. The structure is ingenious and the operation is reliable. The driving ramp 7 can also be an arc surface or a curved surface, as long as it can guide the driving boss 8 to move along the ramp.

[0031] In this embodiment, the clutch structure includes a drive spring 9. The drive spring 9 is disposed between the output member 2 and the drive mechanism 4, and provides a force to propel the output member 2 toward the handle 3, causing the second transmission boss 6 to enter the rotation path of the first transmission boss 5. By providing the drive spring 9, after the second transmission boss 6 exits the rotation path of the first transmission boss 5, the drive spring 9 can drive the output member 2 to reset in a direction closer to the handle 3, causing the second transmission boss 6 to re-enter the rotation path of the first transmission boss 5, preparing for the next closing operation.

[0032] In this embodiment, the drive spring 9 can be a disc spring, a wave spring, or other elastic element that can provide axial restoring force.

[0033] In this embodiment, the first transmission boss 5 includes opposing first side surface 10 and second side surface 11 along the circumference of the handle 3, and the second transmission boss 6 includes opposing third side surface 12 and fourth side surface 13 along the circumference of the handle 3. When the second transmission boss 6 is located within the rotation path of the first transmission boss 5, the first side surface 10 is opposite to the third side surface 12, and the second side surface 11 is opposite to the fourth side surface 13. Along the axial direction of the handle 3, at least one of the first side surface 10, second side surface 11, third side surface 12, and fourth side surface 13 is provided with a guide slope 14. By providing the guide slope 14, the second transmission boss 6 can easily pass over the first transmission boss 5, allowing the output component 2 to move smoothly along the axial direction of the handle 3 after the clutch is engaged, avoiding hard collisions between the second transmission boss 6 and the first transmission boss 5, and ensuring the smoothness of the clutch engagement / disengagement action.

[0034] In this embodiment, the guide slope 14 can also be an arc-shaped surface, as long as it can guide the second transmission boss 6 to pass over the first transmission boss 5.

[0035] In this embodiment, the electric operating module also includes a free position detection switch 15 disposed within the housing 1. The second transmission boss 6 is used to trigger the free position detection switch 15 when the output component 2 is in the free position. By setting the free position detection switch 15, it is possible to detect whether the output component 2 is in the free position state, providing a position signal for the control logic of the electric operating module, and ensuring accurate control of closing and opening operations.

[0036] In this embodiment, a radial boss 16 is provided on the radial sidewall of the handle 3. The electric operating module also includes a trip position detection switch 17 disposed within the housing 1, and the radial boss 16 is used to trigger the trip position detection switch 17 when the handle 3 is in the trip position. And / or, the electric operating module also includes a closing position detection switch 18 disposed within the housing 1, and the radial boss 16 is used to trigger the closing position detection switch 18 when the handle 3 is in the closing position. By setting the trip position detection switch 17 and the closing position detection switch 18, it is possible to detect whether the handle 3 is in the trip position and the closing position respectively, providing position signals for the control logic of the electric operating module. The radial boss 16 rotates with the handle 3, which can accurately trigger the corresponding detection switch, ensuring the reliability of position detection.

[0037] In this embodiment, the electric operating module further includes a locking position detection switch 19, a linkage 20, and a locking member 21 disposed within the housing 1. Both the linkage 20 and the locking member 21 are rotatably mounted on the housing 1. Each linkage 20 and locking member 21 has an active arm and a driven arm relative to its own rotation center, with the active arm of the locking member 21 located on the rotation path of the driven arm of the linkage 20. The radial sidewall of the output member 2 is provided with an output member radial boss 22. This radial boss 22 drives the active arm of the linkage 20 to rotate when the output member 2 switches from the free position to the locked position by rotation. This causes the driven arm of the linkage 20 to drive the active arm of the locking member 21 to rotate and trigger the locking position detection switch 19. Through the cooperation of the linkage 20 and the locking member 21, the locking function of the output member 2 after opening is achieved. The output member radial boss 22 drives the linkage 20 to rotate, and the driven arm of the linkage 20 drives the active arm of the locking member 21 to rotate, thereby triggering the locking position detection switch 19 and realizing the detection of the locked position. Both the linkage 20 and the locking component 21 are lever structures, which are simple in structure and reliable in transmission.

[0038] In this embodiment, the electric operating module further includes a reset component disposed on the housing 1. The reset component is a reset torsion spring 23, which is connected to the driven arm of the locking component 21. And / or, it also includes a limiting part 24 disposed on the housing 1. The limiting part 24 is located on the side of the driven arm of the linkage 20 away from the driving arm of the locking component 21, and is used to limit the rotation angle of the driven arm of the linkage 20. By providing the reset torsion spring 23, the automatic reset of the locking component 21 is achieved, ensuring that the locking component 21 can return to its initial position after unlocking. By providing the limiting part 24, the rotation range of the linkage 20 is limited, preventing excessive rotation of the linkage 20 and affecting the reliability of the locking function.

[0039] This embodiment is not limited to this; the reset element can also be a tension spring or other elastic element that can provide a reset force.

[0040] In this embodiment, the first transmission boss 5 and the handle radial boss 16 are located at the same position around the handle 3.

[0041] In this embodiment, the driving boss 8 and the radial boss 22 of the output component are located at the same position in the circumferential direction of the output component.

[0042] In this embodiment, the operation process of the electric operation module is as follows: In the open position free state, the second transmission boss 6 of output component 2 triggers the free position detection switch 15, and the handle radial boss 16 of handle 3 triggers the open position detection switch 17. Output component 2 is fixed in position by the output shaft of drive mechanism 4, and handle 3 is fixed in position by linkage with the circuit breaker side handle. Locking component 21 is fixed by reset torsion spring 23, and linkage component 20 is fixed in position by locking component 21 and reset torsion spring 23.

[0043] During the closing process, upon receiving the closing signal, the drive mechanism 4 drives the output component 2 to rotate counterclockwise. The second transmission boss 6 abuts against the first transmission boss 5 in the circumferential direction of the handle 3, causing the handle 3 to rotate. The output component 2 continues to rotate counterclockwise until the drive boss 8 abuts against the drive ramp 7 on the housing 1. The drive boss 8 slides along the drive ramp 7, causing the output component 2 to move away from the handle 3, and the drive spring 9 is compressed. When the closing position is reached, the handle 3 is in the closed position, and the handle radial boss 16 triggers the closing position detection switch 18. The output component 2 continues to rotate counterclockwise, the second transmission boss 6 passes over the first transmission boss 5, the drive boss 8 disengages from the drive ramp 7, the drive spring 9 drives the output component 2 to move and reset in the direction closer to the handle 3, and the second transmission boss 6 triggers the free position detection switch 15, entering the closed free state.

[0044] After manual tripping, output component 2 rotates counterclockwise from its free position until the front side of the radial boss 22 of the output component abuts against the side of the active arm of the linkage component 20 facing the radial boss 22 of the output component, causing the active arm of the linkage component 20 to rotate. The end of the active arm of the linkage component 20 facing the side of the radial boss 22 of the output component passes the front side of the radial boss 22 of the output component and abuts against the radial surface of the radial boss 22 of the output component, reaching the locked position. During the rotation of the active arm of the linkage component 20, the driven arm of the linkage component 20 drives the active arm of the locking component 21 to rotate, and the active arm of the locking component 21 triggers the locked position detection switch 19. When unlocking, a signal is sent to the circuit board via a button or signal to drive the drive mechanism 4 to rotate the output component 2 clockwise until the second transmission boss 6 triggers the free position detection switch 15, returning to the tripped free state.

[0045] The circuit breaker provided in this embodiment includes the above-mentioned electric operating module.
