The tripping mechanism includes a trip unit and a tripping element. The tripping mechanism and the reset driving mechanism are located on both sides of the interlocking module. The interlocking module includes: an interlocking element that can slide between a first position and a second position; a locking structure disposed on the sliding path of the interlocking element for locking the interlocking element in the first position; an energy storage mechanism connected to the interlocking element for driving the interlocking element to move from the first position to the second position; a reset structure coupled to the interlocking element and driven by the reset driving mechanism for driving the interlocking element to return from the second position to the first position; and a connecting rod coupled at both ends to the tripping element and the interlocking element, respectively.

Description

Technical Field

[0001] This utility model relates to the field of switching electrical appliances, specifically to a remotely resettable tripping device and circuit breaker. Background Technology

[0002] As a core protection component of low-voltage power distribution systems, circuit breakers, upon detecting a fault current, trigger the tripping mechanism via a tripping device to disconnect the circuit. After the circuit is disconnected, the tripping half-shaft remains locked in a non-automatic reset state. In existing technologies, manual intervention is typically required for resetting after fault clearance. While some circuit breakers attempt to replace manual operation with electric reset devices, current solutions generally suffer from complex structures and large sizes. Furthermore, they often employ multi-stage transmission mechanisms or integrated electronic control modules, resulting in a bulky overall structure and significantly increased manufacturing costs. Utility Model Content

[0003] The purpose of this invention is to overcome at least one defect of the prior art and provide a tripping device that can be remotely reset.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] In a first aspect, this application provides a remotely resettable tripping device, including a tripping mechanism and a reset driving mechanism. The tripping mechanism includes a tripping unit and a tripping element. The tripping unit is used to drive the tripping element to move from an initial position to a tripping trigger position.

[0006] It also includes an interlocking module, wherein the tripping mechanism and the reset drive mechanism are respectively disposed on both sides of the interlocking module, and the interlocking module includes:

[0007] The interlocking element is capable of sliding between a first position and a second position;

[0008] A locking structure is provided on the sliding path of the interlocking member to lock the interlocking member in the first position;

[0009] An energy storage mechanism, connected to an interlocking component, is used to drive the interlocking component to move from a first position to a second position;

[0010] The reset structure, coupled with the interlocking component, is driven by the reset drive mechanism and is used to drive the interlocking component from the second position back to the first position;

[0011] The connecting rod is coupled to the release element and the interlocking element at both ends, respectively.

[0012] When the tripping mechanism drives the tripping component to move from the initial position to the tripping trigger position, it pushes the interlocking component to disengage from the locking structure through the connecting rod. The interlocking component is driven to the second position by the energy storage mechanism and is limited to the tripping component at the tripping trigger position through the connecting rod.

[0013] When the reset drive mechanism drives the reset structure to return the interlocking component to the first position, it releases the limit on the tripping component.

[0014] In one possible implementation, when the interlocking member moves to the first position, it drives the linkage, which in turn pushes the tripping member back to the initial position. Alternatively, the tripping device may further include a return spring connected to the tripping member or the linkage. When the return drive mechanism drives the interlocking member back to the first position, it avoids the linkage, and the return spring drives the tripping member back to the initial position.

[0015] In one possible implementation, the interlocking module further includes a bracket, the interlocking element is slidably mounted on the bracket, the interlocking element and the connecting rod are respectively arranged parallel to the bracket, and the release element is rotatably mounted with its rotation axis perpendicular to the bracket.

[0016] In one possible implementation, the reset structure spans both sides of the bracket, with one end integrally connected to an interlocking element on one side of the bracket, and the other end extending to the other side of the bracket and positioned opposite to the output end of the reset mechanism.

[0017] In one possible implementation, the locking structure also locks the interlocking element in a second position.

[0018] In one possible implementation, the interlocking member has a stepped first guide portion, which has a first locking surface and a second locking surface. When the interlocking member is in the first position and the second position, it contacts and limits the locking structure through the first locking surface and the second locking surface, respectively. The energy storage mechanism drives the first guide portion to move toward the locking structure.

[0019] In one possible implementation, the locking structure is provided with a first guide groove, and the first guide portion is slidably engaged with the first guide groove.

[0020] In one possible implementation, the energy storage mechanism acts on the interlocking member in the direction of its elastic force, and is inclined to the direction of movement of the interlocking member, comprising a first component force and a second component force that are perpendicular to each other:

[0021] The first component force, parallel to the direction of movement of the interlocking component, is used to provide preload force for limiting the contact between the first locking surface and the second locking surface and the locking structure;

[0022] The second component force, perpendicular to the direction of movement of the interlocking component, is used to drive the locking component to sink to the bottom of the first guide groove.

[0023] In one possible implementation, the locking structure protrusion is provided on the side of the bracket, the first guide portion is embedded in the first guide groove and spaced apart from the bracket, the first connecting end of the connecting rod is inserted between the first guide portion and the bracket, and a sliding shaft is provided on the side, and the first guide portion is provided with a first sliding groove that is nested on the sliding shaft for sliding engagement.

[0024] In one possible implementation, the bracket is provided with a guide plate spaced apart from the locking structure, and the first connecting end of the connecting rod passes between the locking structure and the guide plate.

[0025] In one possible implementation, the release element has a first interlocking end that cooperates with the connecting rod, the first interlocking end has a second sliding groove on the side facing the bracket, the second connecting end of the connecting rod has two sliding platforms, the second connecting end passes through the second sliding groove and is located between the release element and the bracket, while the first interlocking end of the release element is nested between the two sliding platforms.

[0026] In one possible implementation, the bracket is provided with a guide structure, the guide structure is provided with a second guide groove, the first guide groove and the second guide groove are arranged along the movement direction of the sliding member, and the interlocking member is provided with a second guide part that is slidably engaged with the second guide groove.

[0027] In one possible implementation, the interlocking member has a sheet-like structure, including a first guide portion and a second guide portion respectively disposed at both ends. The end of the first guide portion away from the second guide portion is integrally and perpendicularly connected to the reset structure. The first guide portion has a stepped protrusion, and its side is provided with a first locking surface and a second locking surface. The interlocking member is provided with a hook structure between the first guide portion and the second guide portion for connecting the energy storage mechanism.

[0028] In one possible implementation, the bracket has a flange, which is arranged opposite to the opening direction of the first guide groove and the second guide groove. An interlocking member is arranged between the flange and the first guide groove and the second guide groove, and the first guide groove and the second guide groove are offset along the groove depth direction.

[0029] In one possible implementation, the device housing is also included, in which the interlocking module, tripping mechanism, tripping element, and reset drive mechanism are disposed. The reset drive mechanism, interlocking module, and tripping mechanism are arranged side by side in sequence along a first direction. The tripping mechanism and reset drive mechanism are respectively located on both sides of the interlocking module. The output end of the tripping mechanism moves linearly along a second direction. The tripping element is located on one side of the interlocking module and tripping mechanism in the second direction. The first direction is perpendicular to the second direction.

[0030] In one possible implementation, the output end of the reset drive mechanism moves linearly along a third direction, with the first direction, the second direction, and the third direction being mutually perpendicular; both the tripping mechanism and the reset drive mechanism are electromagnetic mechanisms, and their output ends are linearly moving push rods; the interlocking member and the connecting rod slide parallel to the plane containing the second direction and the third direction.

[0031] In one possible implementation, when the energy storage mechanism drives the interlocking component to move upward to the second position, the interlocking component drives the push rod of the reset drive mechanism to reset via an integrated reset structure.

[0032] In one possible implementation, the device housing is further provided with a reset member, and the tripping mechanism includes a tripping push rod as an output end and a tripping coil for driving the tripping push rod to move. The tripping push rod is a stepped shaft structure, which includes a through part and a limiting part. The connection between the two is formed by a diameter difference to form a tripping step. The through part passes through the tripping member. When the tripping mechanism is activated, it drives the tripping push rod to push out and pushes the tripping member to rotate from the initial position to the tripping trigger position through the tripping step.

[0033] The reset component and the tripping mechanism are located on opposite sides of the tripping component. The reset component is used to push the through part, thereby driving the tripping push rod to reset into the tripping coil.

[0034] In one possible implementation, the reset element is rotatably disposed within the device housing, which has a spindle mounting groove sleeved on the spindle. The spindle mounting groove is semi-circular and has a cantilever movement channel. When the circuit breaker is tripped, the reset cantilever on the spindle passes through the cantilever movement channel and pushes the reset drive unit to cause the reset element to push the trip push rod to reset. The reset cantilever continuously provides axial support force for the trip push rod.

[0035] In one possible implementation, the tripping element is flat, with its side facing the tripping mechanism, and its central part having an interlocking groove that engages with the tripping device. Both ends of the tripping element are respectively provided with:

[0036] The first interlocking end includes a first mounting shaft rotatably connected to the bracket, and a first interlocking part located on one side of the first mounting shaft in the radial direction. The first interlocking part is used to couple the second connecting end of the connecting rod.

[0037] The second interlocking end includes a second mounting shaft coaxially arranged with the first mounting shaft, and a second interlocking part located on one side of the second mounting shaft in the radial direction. The second mounting shaft is rotatably connected to the device housing, and the second interlocking part extends to the outside of the device housing for pushing and locking the tripping half shaft.

[0038] In one possible implementation, the reset drive mechanism includes:

[0039] The reset electromagnetic mechanism is used to push the reset structure, causing it to reset the interlocking components.

[0040] The second micro switch is connected in series with the power supply circuit of the reset electromagnetic mechanism. When the interlocking element is in the second position, the power supply circuit is closed, and when the interlocking element is in the first position, the power supply circuit is opened.

[0041] The first micro switch is used to provide feedback on the operation status of the interlocking component.

[0042] In one possible implementation, the trigger rods of the first and second microswitches are arranged in parallel and offset along the moving direction of the reset structure. The reset structure includes a planar reset plate with a raised trigger structure. The reset structure triggers the first and second microswitches respectively through the reset plate and the trigger structure. Alternatively, the trigger rods of the first and second microswitches are arranged vertically. The reset structure includes a planar reset plate with a raised trigger plate on its side. The trigger plate is inclined to the reset plate, and the reset plate and the trigger plate are used to trigger the first and second microswitches respectively.

[0043] In one possible implementation, the reset electromagnetic mechanism includes a base and a cover plate. The base includes two side plates and two partitions integrally connected between the two side plates. The reset electromagnetic mechanism also includes a magnetic yoke, a reset coil, a stationary iron core, a moving iron core, and a reset push rod disposed in a cavity formed between the two side plates and the two partitions. The two side plates extend to form extensions, and the inner walls of the extensions are provided with positioning grooves. The first end of the L-shaped cover plate is inserted between the two extensions and is limited by the positioning grooves on both sides. The magnetic yoke is provided with a clearance hole for the moving iron core to pass through, and the second end is provided with a limiting boss corresponding to the clearance hole. The moving iron core passes through the clearance hole and contacts and is limited by the limiting boss. The base is provided with a mounting post for mounting a second micro switch, and the first end of the cover plate axially limits the second micro switch to the mounting post.

[0044] In one possible implementation, a raised mounting plate is provided on the partition located on the side away from the extension, and the mounting plate is fixedly connected to the device housing by screws; or, the mounting plate is provided with a second buckle, which is limitedly connected to the device housing.

[0045] Secondly, this application provides a circuit breaker including the remotely resettable tripping device.

[0046] This utility model discloses a remotely resettable tripping device, in which the tripping mechanism and the reset drive mechanism are laterally placed on both sides of the interlocking module. The interlocking module includes an interlocking component, a locking structure, an energy storage mechanism, and a connecting rod. The connecting rod cooperates with the tripping component of the tripping mechanism. The interlocking component cooperates with the reset drive mechanism through the reset structure. Through the locking cooperation between the slidably set interlocking component and the locking structure, the tripping component is locked in the tripping trigger position, and the locking of the tripping component can be released by the reset drive mechanism. The overall structure is simple, with few parts, which can effectively reduce the size of the tripping device.

[0047] Furthermore, the reset drive mechanism, interlocking module, and tripping mechanism are arranged side by side in sequence along the first direction. The tripping mechanism and reset drive mechanism are respectively placed on both sides of the interlocking module. The output end of the tripping mechanism moves linearly along the second direction. The tripping element is located on one side of the interlocking module and the tripping mechanism in the second direction. The interlocking element and connecting rod slide parallel to the plane containing the second and third directions. This makes the thickness of the interlocking module very thin in the first direction, resulting in a small overall space occupation. Through the planar layout design of the interlocking module, not only is the volume of the interlocking module itself significantly reduced, but the horizontal layout also avoids the vertical stacking of the tripping mechanism and the reset drive mechanism, significantly reducing the volume of the tripping device and adapting to the installation space of universal circuit breakers with limited height.

[0048] Furthermore, by designing the tripping component and the interlocking component to rotate and slide linearly respectively, and coupling them together via a linkage, not only can the rotating tripping component match the movement trajectory of the tripping half-shaft, enabling rapid triggering and locking of the tripping half-shaft during tripping, but the linearly sliding interlocking component is also easier to integrate into the interlocking module, eliminating the need for rotational space and reducing module complexity.

[0049] Furthermore, the reset drive mechanism does not require complex circuit boards or complex multi-stage transmissions. It achieves reset by directly driving the interlocking components with an electromagnet, balancing cost and stability. Moreover, the base and cover plate are assembled with snap-fit, which simplifies assembly and saves space.

[0050] Furthermore, when the energy storage mechanism drives the interlocking component to move upward to the second position, the interlocking component drives the push rod of the reset drive mechanism to reset through the integrated reset structure, eliminating the need for a separate reset spring for the drive mechanism, thus reducing costs and minimizing the overall size of the tripping device.

[0051] In addition, the tripping mechanism is reset by cooperating with the main shaft of the circuit breaker through the reset component. When the circuit breaker is in the open state, the main shaft continuously presses against the tripping push rod through the reset cantilever, and the tripping push rod cannot push out to drive the tripping component to rotate. After the circuit breaker is closed, the main shaft rotates to the main shaft closed position, the reset component is reset, and when the tripping mechanism is energized, it triggers the tripping push rod to push the tripping component to rotate and drive the open half shaft, so that the circuit breaker trips.

[0052] This invention also provides a circuit breaker, including the remotely resettable tripping device, which significantly reduces the overall height through the planar interlocking module and the lateral partitioning design of the tripping device, making it suitable for circuit breaker installation in confined spaces.

[0137] The following description, in conjunction with the accompanying drawings, further illustrates the specific implementation of the remotely resettable tripping device of this utility model. The remotely resettable tripping device of this utility model is not limited to the description in the following embodiments.

[0138] This embodiment features a remotely resettable tripping device installed on a circuit breaker. The circuit breaker in this embodiment (not shown in the figure) is a universal circuit breaker (frame-type circuit breaker). The circuit breaker typically includes a housing, an operating mechanism, a tripping device, a drive mechanism, and at least one switch module. The switch module includes a contact system, an arc-extinguishing mechanism, and two wiring mechanisms. The contact system includes a moving contact, a stationary contact, a contact support, and a contact spring. The moving contact is mounted on the contact support and connected to the contact spring. The moving contact and the stationary contact are connected to the circuit through corresponding wiring mechanisms. The contact support can drive the moving contact to contact and separate from the stationary contact to respectively connect and disconnect the connected circuit, thereby achieving closing and opening.

[0139] The circuit breaker housing includes a base, multiple switch modules are installed inside the base, and the operating mechanism is mounted on the base. The operating mechanism includes a rotatably mounted main shaft and a drive shaft. The main shaft is rotatable between a main shaft closed position and a main shaft open position. A contact cantilever is mounted on the main shaft, and the contact cantilever is connected to the contacts via a contact connecting rod. The operating mechanism also includes:

[0140] The energy storage mechanism includes a closing spring and a opening spring, which are used to provide closing driving force and opening driving force, respectively. The energy storage mechanism drives the main shaft to rotate between the main shaft closing position and the main shaft opening position through a linkage mechanism. When the main shaft rotates, it drives the moving contact to contact and separate from the stationary contact, so as to realize closing and opening respectively.

[0141] The linkage mechanism includes a transmission component, a trip latch, and a locking latch. The transmission component and the trip latch are connected by a hinge shaft. The locking latch is used to lock the position of the trip latch and lock the trip spring in a compressed state through the trip latch.

[0142] The cam mechanism is connected to the drive shaft. Under the drive of the drive shaft, it compresses the closing spring, so that the energy storage mechanism stores energy.

[0143] The tripping half-shaft is used to trigger the operating mechanism to trip. It can be driven by the tripping button, tripping device or other mechanism to trigger the latch and tripping latch to unlock and release the tripping spring, so that the operating mechanism trips.

[0144] refer to Figure 1-2 The tripping device in this embodiment is a remotely resettable tripping device, including a tripping mechanism 1, a tripping element 2, and a reset driving mechanism 6. The tripping mechanism 1 includes a tripping electromagnet. When the circuit breaker detects a fault current, the tripping electromagnet actuates and drives the tripping element 2 to move from the initial position to the tripping trigger position. The tripping element 2 pushes the tripping half shaft to trigger the tripping operation mechanism and locks the tripping half shaft in a non-resettable state. After the fault is cleared, the reset driving mechanism 6 drives the tripping element 2 to unlock the tripping half shaft, so that the tripping half shaft is in a resettable state, and the latch and trip latch can be re-locked.

[0145] The closing process of the circuit breaker in this embodiment is as follows: (1) Energy storage stage: The drive shaft rotates under the drive of the drive mechanism, and the cam mechanism compresses the closing spring, so that the closing spring enters the energy storage state. The drive mechanism is a manual operating handle and / or a motor. (2) When the circuit breaker is in the open state and the operating mechanism is in the energy storage state, the closing button can be pressed to drive the energy storage mechanism to release energy or the closing electromagnetic mechanism can be remotely controlled to drive the energy storage mechanism to release energy. The released closing spring pushes the linkage mechanism to drive the main shaft to rotate. The main shaft drives the contact support to rotate through the contact cantilever, so that the contact support drives the moving contact to close with the stationary contact to achieve closing. At this time, the trip latch and the lock latch are in the interlocked state, and the opening spring is locked in the compressed state.

[0146] The tripping process is as follows: (1) Press the tripping button or remotely control the tripping electromagnetic mechanism to drive the tripping half shaft. The tripping half shaft triggers the latch and tripping latch to unlock and release the tripping spring; (2) The released tripping spring drives the main shaft to rotate through the linkage mechanism. The main shaft drives the contact support to rotate through the contact cantilever, so that the contact support drives the moving contact to separate from the stationary contact to achieve tripping.

[0147] The tripping process caused by a fault trip is as follows: (1) When the circuit breaker detects a fault current, the tripping mechanism 1 of the tripping device is activated, and the tripping half shaft is pushed by the tripping component 2. The tripping half shaft triggers the latch and tripping latch to unlock and release the tripping spring. The tripping component 2 locks the tripping half shaft synchronously, locking the tripping half shaft in a state that cannot be reset, so that the latch and tripping latch cannot be re-locked. The released tripping spring drives the main shaft to rotate through the linkage mechanism. The main shaft drives the contact support to rotate through the contact cantilever, so that the contact support drives the moving contact to separate from the stationary contact to achieve tripping; (2) After the fault is cleared, a reset signal can be sent remotely to the reset drive mechanism 6. The reset drive mechanism 6 is activated, and the tripping component 2 is driven by the reset drive mechanism 6 to release the limit on the tripping half shaft, so that the tripping half shaft can be reset, the latch and tripping latch can be re-locked, and the circuit breaker can perform a closing operation. This is the prior art in this field and will not be described in detail.

[0148] like Figure 1-4 As shown, an improvement in this embodiment is that the remotely resettable tripping device further includes an interlocking module. The tripping mechanism 1 and the reset driving mechanism 6 are respectively disposed on both sides of the interlocking module. The interlocking module includes:

[0149] Interlocking member 31 is capable of sliding between a first position and a second position;

[0150] The locking structure 4 is disposed on the sliding path of the interlocking member 31 and is used to lock the interlocking member 31 in the first position;

[0151] Energy storage mechanism 5 is connected to interlocking component 31 and is used to drive interlocking component 31 to move from the first position to the second position;

[0152] The reset structure 32 is coupled to the interlocking member 31 and is driven by the reset drive mechanism 6 to drive the interlocking member 31 from the second position back to the first position.

[0153] Link 8 is coupled at both ends to the release mechanism 1 and the interlocking component 31, respectively.

[0154] When the tripping mechanism 1 drives the tripping component 2 to move from the initial position to the tripping trigger position, the interlocking component 31 is pushed away from the locking structure 4 by the connecting rod 8. The interlocking component 31 is driven to the second position by the energy storage mechanism 5, and the tripping component 2 is limited to the tripping trigger position by the connecting rod 8, so that the tripping component 2 locks the tripping half shaft in a state that cannot be reset.

[0155] When the reset drive mechanism 6 drives the reset structure 32 to return the interlocking component 31 to the first position, it releases the limit on the tripping component 2, so that the tripping half shaft is in a resettable state.

[0156] For example, when the interlocking member 31 moves to the first position, it drives the connecting rod 8, which in turn pushes the tripping member 2 back to the initial position. Alternatively, the tripping device may also include a reset spring 9 connected to the tripping member 2 or the connecting rod 8. When the reset driving mechanism 6 drives the interlocking member 31 back to the first position, it avoids the connecting rod 8, and the reset spring 9 drives the tripping member 2 back to the initial position, so that the tripping half shaft is in a resettable state.

[0157] The remotely resettable tripping device of this embodiment has the tripping mechanism 1 and the reset drive mechanism 6 horizontally placed on both sides of the interlocking module. The interlocking module includes an interlocking component 31, a locking structure 4, an energy storage mechanism 5, and a connecting rod 8. The connecting rod 8 cooperates with the tripping component 2 of the tripping mechanism 1. The interlocking component 31 cooperates with the reset drive mechanism through the reset structure 32. Through the locking cooperation between the slidingly arranged interlocking component 31 and the locking structure 4, the tripping component 2 is locked in the tripping trigger position, and the lock on the tripping component 2 can be released by the reset drive mechanism 6. The overall structure is simple, with few parts, which can effectively reduce the size of the tripping device.

[0158] like Figure 1-2 As shown, this preferred embodiment also includes a device housing 100. The interlocking module, tripping mechanism 1, tripping element 2, and reset drive mechanism 6 are disposed in the device housing 100, integrated into a single module, and integrally installed into the circuit breaker. The tripping device has a first direction, a second direction, and a third direction that are mutually perpendicular to each other. The first direction is parallel to the width direction of the remotely resettable tripping device. Figure 2 The left and right directions), and the second direction is parallel to the height direction of the remotely resettable tripping device. Figure 2 The vertical direction is parallel to the thickness direction of the remotely resettable tripping device (perpendicular to the vertical direction). Figure 2 (Up and down direction). It is understood that the width, height, and thickness directions of the remotely resettable tripping device are the same as the width, height, and thickness directions of the circuit breaker.

[0159] Preferably, the device housing 100 is disposed on the side of the controller along a third direction and on the side of the operating mechanism along a first direction. A transformer 110 for powering the controller is provided on the bottom outer side of the device housing 100. The reset drive mechanism 6, the interlocking module, and the tripping mechanism 1 are arranged side by side along the first direction, located in the upper half of the device housing 100 in the height direction. The tripping mechanism 1 and the reset drive mechanism 6 are respectively placed on both sides of the interlocking module. The output end of the tripping mechanism 1 moves linearly along a second direction. The tripping element 2 is located on one side of the interlocking module and the tripping mechanism 1 in the second direction. Figure 2The tripping component 2 is located on the back of the tripping mechanism 1 and is blocked by the tripping mechanism 1. The interlocking component 31 and the connecting rod 8 slide parallel to the plane of the second direction and the third direction. The device housing 100 is located on one side of the radial direction of the tripping half shaft and is provided with a through hole for the tripping component 2 to pass through. The tripping component 2 extends through the through hole to the radial side of the tripping half shaft.

[0160] Thus, the interlocking module is very thin in the first direction and occupies little space overall. Through the planar layout design of the interlocking module, the tripping mechanism and the reset drive mechanism are placed laterally on both sides, which not only significantly reduces the volume of the interlocking module itself, but also avoids the vertical stacking of the tripping mechanism 1 and the reset drive mechanism 6 through the lateral layout, significantly reducing the volume of the tripping device and adapting to the installation space of universal circuit breakers with limited height.

[0161] In this embodiment, both the tripping mechanism 1 and the reset driving mechanism 6 are electromagnetic mechanisms, and their output ends are linearly moving push rods; preferably, the output end of the reset driving mechanism 6 moves linearly in a third direction. Preferably, the width of the interlocking module in the first direction is less than 20% of the width of the device housing 100. Of course, as another embodiment, the output end of the reset driving mechanism 6 can also be arranged in a second direction, but a transmission structure needs to be added, increasing the volume.

[0162] like Figure 1-2 As shown, this embodiment also includes a reset member 12 for resetting the tripping mechanism 1. The tripping mechanism 1 includes a tripping push rod 11 as an output end and a tripping coil (not shown in the figure) for driving the tripping push rod 11 to move. Preferably, the tripping push rod 11 is a stepped shaft structure, which includes a through part and a limiting part. The connection between the two is formed by the diameter difference to form a tripping step. The through part passes through the tripping member 2. When the tripping mechanism 1 moves, it drives the tripping push rod 11 to push out and pushes the tripping member 2 from the initial position to the tripping trigger position through the tripping step.

[0163] The reset element 12 and the tripping mechanism 1 are respectively located on both sides of the tripping element 2, and the reset element 12 is located in the direction of movement of the tripping push rod 11. Preferably, the reset element 12 is driven by the main shaft of the circuit breaker. After the circuit breaker is opened, that is, when the main shaft rotates to the main shaft open position, the reset element 12 is driven. Under the drive of the main shaft, the reset element 12 pushes the through part, which drives the tripping push rod 11 to reset into the tripping coil, and continuously provides axial support for the tripping push rod 11, so that the tripping push rod 11 is kept in the tripping coil, preparing for the next push-out. When the circuit breaker is in the open state, the main shaft continuously pushes the tripping push rod 11 through the reset cantilever, and the tripping push rod 11 cannot push out to drive the tripping element 2 to rotate. After the circuit breaker is closed, the main shaft rotates to the main shaft closed position, the reset element 12 is reset, and when the tripping mechanism 1 is energized, it triggers the tripping push rod 11 to push the tripping element 2 to rotate, which drives the open half shaft, so that the circuit breaker is tripped.

[0164] In a preferred embodiment, the reset member 12 is rotatably disposed within the device housing 100. The device housing 100 is provided with a spindle mounting groove 101 sleeved on the spindle. The spindle is provided with a reset cantilever (not shown in the figure) coupled to the reset member 12. The spindle mounting groove 101 is semi-circular and has a cantilever movement channel. The reset member 12 is rotatably disposed and is provided with a reset drive unit corresponding to the cantilever movement channel. After the circuit breaker is tripped, the spindle rotates to the spindle tripped position. The reset cantilever on the spindle passes through the cantilever movement channel and pushes the reset drive unit to cause the reset member 12 to push the trip push rod 11 to reset. The reset member 12 continuously provides axial support force to the trip push rod 11.

[0165] In this preferred embodiment, the reset is driven by the reset member 12, and there is no need to set a spring for driving the release push rod 11 to reset. Therefore, there is no structural limitation of the release mechanism 1 by the spring, which allows the release mechanism 1 to be made larger as a whole, ensuring the reliability and response speed during operation, but without hindering the action of the release push rod 11 due to the spring.

[0166] like Figure 3 In the preferred embodiment shown, the interlocking module further includes:

[0167] A bracket 7, installed within the device housing 100, is positioned between the tripping mechanism 1 and the reset drive mechanism 6. The interlocking member 31 is slidably mounted on the bracket 7. The interlocking member 31 and the connecting rod 8 are respectively arranged parallel to the bracket 7. The interlocking member 31 is primarily anti-slip along a third direction. The output end of the reset drive mechanism 6 moves linearly along a third direction. The tripping member 2 is rotatably mounted with its rotation axis perpendicular to the bracket 7. A reset spring 9 is also included, connecting the bracket 7 and the tripping member 2, and is used to drive the tripping member 2 back to its initial position. The design of the tripping member 2 rotating and the interlocking member 31 sliding linearly allows the rotating tripping member 2 to match the movement trajectory of the tripping half-shaft, quickly triggering and locking the tripping half-shaft during tripping. Furthermore, the linearly sliding interlocking member 31 is easier to integrate into the interlocking module, eliminating the need for rotational space and reducing module complexity. Alternatively, the bracket 7 can be omitted, and the tripping member 2 and the interlocking member 31 can be mounted on the device housing 100, or on the tripping mechanism 1 or the reset drive mechanism 6. In addition, the reset spring 9 provides an auxiliary force for the release member 2 to reset. Alternatively, the reset spring 9 can be omitted, and the release member 2 can be reset by the linkage 8.

[0168] like Figure 5-6As shown, the interlocking component 31 and the reset structure 32 are integral parts, arranged vertically. The reset structure 32 is flat and spans both sides of the bracket 7. One end of the reset structure 32 is integrally connected to the interlocking component 31 on one side of the bracket 7, and the other end extends to the other side of the bracket 7 and is positioned opposite to the output end of the reset drive mechanism 6. Alternatively, the reset structure 32 can be separately arranged from the interlocking component 31. For example, the reset structure 32 and the interlocking component 31 can be separately arranged and then mechanically linked. The reset structure 32 is driven by the reset drive mechanism 6 to directly push the interlocking component 31, or the linkage between the two can be achieved through gears and racks.

[0169] like Figure 8 As shown, the tripping component 2 is flat, with its side facing the tripping mechanism 1. Its central part has an interlocking groove 20 that engages with the tripping device. Both ends of the tripping component 2 are respectively provided with:

[0170] The first interlocking end includes a first mounting shaft 211 rotatably connected to the bracket 7, and a first interlocking part 212 located on one side of the first mounting shaft 211 in the radial direction, the first interlocking part 212 being coupled to the connecting rod 8;

[0171] The second interlocking end includes a second mounting shaft 221 coaxially arranged with the first mounting shaft 211, and a second interlocking part 222 located on one radial side of the second mounting shaft 221. The second mounting shaft 221 is rotatably connected to the device housing 100, and the second interlocking part 222 extends to the outside of the device housing 100 for pushing and locking the tripping half shaft. Driven by the interlocking groove 20 in the middle cooperating with the tripping mechanism 1, and with both ends cooperating with the tripping half shaft and the interlocking member 31 respectively, this not only allows the locking force of the interlocking member 31 to be directly transmitted to the tripping half shaft through the tripping member 2, reliably locking the tripping half shaft, but also results in a more compact structure.

[0172] like Figure 6 As shown, the interlocking member 31 has a sheet-like structure and includes:

[0173] The first guide portion 311 and the second guide portion 315 are respectively disposed at both ends of the interlocking member 31. The end of the first guide portion 311 away from the second guide portion 315 is integrally and vertically connected to the reset structure 32. It is a stepped shape extending perpendicular to the sliding direction. Its side is provided with a first locking surface 312 and a second locking surface 313. The locking structure 4 is provided with a first guide groove 41. The first guide portion 311 is inserted into the first guide groove 41 for sliding cooperation. When the interlocking member 31 is in the first position and the second position, it respectively drives the corresponding first locking surface 312 and the second locking surface 313 to move to the outside of the first guide groove 41 and contact the bottom edge of the first guide groove 41 for limiting.

[0174] The second guide part 315 is located at the end of the interlocking member 31 away from the reset structure 32. The bracket 7 is provided with a protruding guide structure 71. The guide structure 71 is provided with a second guide groove 72. The first guide groove 41 and the second guide groove 72 are arranged along the movement direction of the sliding member 3. The second guide part 315 is inserted into the second guide groove 72 for sliding cooperation.

[0175] The hook structure 314 is located in the middle of the interlocking member 31 and between the first guide portion 311 and the second guide portion 315. The first energy storage end of the energy storage mechanism 5 is connected to the hook structure 314, and the second energy storage end is connected to the bracket 7. The second energy storage end is located on the side of the locking structure 4 and the guide structure 71 away from the interlocking structure 3. The energy storage mechanism 5 acts on the elastic direction of the interlocking member 31 and is inclined to the moving direction of the interlocking member 31. It includes a first component force and a second component force that are perpendicular to each other.

[0176] The first component force, parallel to the direction of movement of the interlocking member 31, is used to provide pre-tightening force for the first locking surface 312 and the second locking surface 313 to contact and limit the locking structure 4.

[0177] The second component force, perpendicular to the moving direction of the interlocking member 31, is used to drive the locking member 31 to sink to the bottom of the first guide groove 41, that is, to drive the first guide part 311 to move towards the locking structure 4.

[0178] Preferably, the bracket 7 is provided with a flange 73, which is arranged opposite to the opening direction of the first guide groove 41 and the second guide groove 72. The interlocking member 31 is disposed between the flange 73 and the first guide groove 41 and the second guide groove 72. The first guide groove 41 and the second guide groove 72 are offset along the groove depth direction. The interlocking member 31 is limited in the first guide groove 41 and the second guide groove 72 by the flange 73.

[0179] In other embodiments, the first guide portion 311 may not have a second buckle surface 313. When the interlocking member 31 is in the second position, it is locked to the bracket 7 by the reset structure 32.

[0180] refer to Figure 3 When the tripping device is triggered due to a malfunction:

[0181] When the tripping mechanism 1 drives the tripping member 2 to move from the initial position to the tripping trigger position, it pushes the interlocking member 31 through the connecting rod 8, so that the first locking surface 312 moves away from the locking structure 4, releasing the interlocking member 31 from the locking structure 4. The energy storage mechanism 5 drives the interlocking member 31 to move upward to the second position, and drives the second locking surface 313 to approach the locking structure 4 and limit it with the locking structure 4. At this time, the locking structure 4 limits the interlocking member 31, and the interlocking member 31 limits the tripping member 2 to the tripping trigger position through the connecting rod 8, so that the tripping member 2 locks the tripping half shaft in a non-reset state, and the circuit breaker cannot be closed.

[0182] When the energy storage mechanism 5 drives the interlocking component 31 to move upward to the second position, the interlocking component 31 drives the push rod of the reset drive mechanism 6 to reset through the integrated reset structure 32. There is no need to set a separate reset spring for the drive mechanism 6, which reduces costs and reduces the overall size of the tripping device.

[0183] refer to Figure 3 When the tripping device is remotely controlled to reset:

[0184] The reset structure 32 is driven by the reset drive mechanism 6 to move the interlocking member 31 downward to return to the first position, and the energy storage mechanism 5 drives the first locking surface 312 to approach the locking structure 4 and limit it with the locking structure 4, thereby releasing the limit on the connecting rod 8. The reset spring 9 drives the tripping member 2 back to the initial position, thereby releasing the limit on the opening half shaft.

[0185] like Figure 3 As shown, both the release element 2 and the interlocking element 3 have gaps with the bracket 7. The connecting rod 8 includes a first connecting end coupled to the interlocking element 3 and a second connecting end coupled to the release element 2. Both are inserted into their respective gaps for sliding engagement. The bracket 7 is provided with a guide plate 74 spaced apart from the locking structure 4. The first connecting end of the connecting rod 8 passes between the locking structure 4 and the guide plate 74. The connecting rod 8 is slidably arranged along the second direction.

[0186] Specifically, the locking structure 4 is protruding on the side of the bracket 7, and the two side walls of the first guide groove 41 are spaced apart from the bracket 7. The first guide part 311 is embedded in the first guide groove 41 and spaced apart from the bracket 7. The first connecting end of the connecting rod 8 is inserted between the first guide part 311 and the bracket 7, and a sliding shaft 82 is provided on the side. The first guide part 311 is provided with a first sliding groove 316 that is nested on the sliding shaft 82 for sliding cooperation.

[0187] The release member 2 is provided with a second sliding groove 213 on the side facing the bracket 7. The depth of the second sliding groove 213 is equal to the distance between the first guide part 311 and the bracket 7. The second connecting end of the connecting rod 8 is provided with two sliding tables 84. The second connecting end passes through the second sliding groove 213, and at the same time, the first interlocking end of the release member 2 is nested between the two sliding tables 84.

[0188] like Figure 1-3 As shown, Figure 9-10 As shown, the reset drive mechanism 6 includes a reset housing composed of a base 61 and a cover plate 62, and components respectively disposed in the base 61:

[0189] The reset electromagnet 63 is used to push the reset structure 32, causing it to drive the interlocking member 31 to reset from the second position to the first position;

[0190] The first micro switch 64 is mounted on the cover plate 62. Normally it can be either normally open or normally closed. When the reset electromagnet 63 is activated, it triggers the first micro switch 64 to switch the output state to provide feedback on the completion of the action.

[0191] The second micro switch 65 is fixed on the mounting post of the base 61 and connected in series with the power supply circuit of the reset electromagnet 63 to control the power supply to the reset electromagnet 63.

[0192] The interlocking component 31 can directly trigger the first micro switch 64 and the second micro switch 65 to switch the output state through the reset structure 32. Alternatively, a trigger element or a boss structure can be installed on the reset structure 32 to trigger the first micro switch 64 and the second micro switch 65 to switch the output state.

[0193] When the interlocking component 31 is in the first position, the second micro switch 65 is in the open state;

[0194] When the interlocking component 31 moves to the second position, the second micro switch 65 is triggered by the reset structure 32 to switch to the closed state, so that it conducts the circuit that supplies power to the reset electromagnet 63. When the reset electromagnet 63 receives the signal, it acts and pushes the interlocking component 31 to reset. After the interlocking component 31 is reset, the second micro switch 65 is triggered to open again, disconnecting the circuit that supplies power to the reset electromagnet 63, preventing the reset electromagnet 63 from being continuously energized, reducing losses and preventing overheating. At the same time, the output state is switched by the first micro switch 64 to provide feedback on the action signal of the interlocking component 31.

[0195] The reset drive mechanism 6 in this embodiment requires neither a complex circuit board nor a complex multi-stage transmission. It achieves reset by directly driving the interlocking component 31 with an electromagnet, balancing cost and stability. Moreover, the snap-fit ​​assembly of the base 61 and the cover plate 62 simplifies assembly and saves space. In addition, the detection mechanism of the first micro switch 64 and the second micro switch 65 improves reliability and makes it suitable for remote reset requirements.

[0196] like Figure 11 As shown, the reset electromagnet 63 includes a yoke 631 and a coil frame 632 disposed inside the yoke 631. A reset coil is wound on the outside of the coil frame 632. A stationary iron core 633, a moving iron core 634, and a reset push rod 635 are disposed inside the coil frame 632.

[0197] After the reset coil is energized, it works in conjunction with the stationary iron core 633 and the magnetic yoke 631 to drive the moving iron core 634 to move. The magnetic yoke 631 is provided with a baffle 636 for limiting the movement of the moving iron core 634. The moving iron core 634 is provided with a reset push rod 635 that passes through the baffle 636. The moving iron core 634 directly pushes the interlocking member 31 to reset through the reset push rod 635.

[0198] like Figure 12-14As shown, the base 61 includes two side plates 611 and two partition plates 612 integrally connected between the two side plates 611. A magnetic yoke 631, a reset coil, a stationary iron core 633, a moving iron core 634, and a reset push rod 635 are disposed in the cavity formed between the two side plates 611 and the two partition plates 612. The two side plates 611 extend to form extensions 613. The inner wall of the extension 613 is provided with positioning grooves 614. The first end 621 of the L-shaped cover plate 62 is inserted between the two extensions 613 and is aligned with the positioning grooves on both sides. The second end 622 is limited by a buckle 623 and a slot 615 on the two side plates 611. The magnetic yoke 631 is provided with a clearance hole 630 for the moving iron core 634 to pass through. The second end 622 is provided with a limiting boss 624 corresponding to the clearance hole 630. The iron core 634 passes through the clearance hole 630 and contacts the limiting boss 624 for limitation. The partition plate 612 located on the side away from the extension 613 is provided with a protruding mounting plate 619. The mounting plate 619 is fixedly connected to the device housing 100 by screws.

[0199] In this embodiment, the moving iron core 634 is limited by the limiting boss 624, eliminating the need to set a separate limiting iron core 634 on the coil frame 632. This reduces the number of parts in the reset electromagnet 63 and also reduces its size.

[0200] Furthermore, the second end 622 of the cover plate 62 is provided with a mounting hole 625 for mounting the first micro switch 64 on the side away from the base 61. The second micro switch 65 is disposed between the first end 621 of the cover plate 62 and the base 61. The base 61 is provided with a mounting post 616 for mounting the second micro switch 65. The first end 621 of the cover plate 62 axially limits the second micro switch 65 to be positioned on the mounting post 616.

[0201] Preferably, the trigger rods of the first micro switch 64 and the second micro switch 65 are arranged in parallel and offset along the moving direction of the reset structure 32. The reset structure 32 includes a planar reset plate 321. The reset plate 321 is provided with a trigger mounting hole 322 for mounting a trigger structure (not shown in the figure). The trigger structure protrudes from the side of the reset plate 321. The reset structure 32 triggers the first micro switch 64 and the second micro switch 65 respectively through the reset plate 321 and the trigger structure.

[0202] like Figure 15-20 Another preferred embodiment of the reset mechanism 6 is shown. In this embodiment, the installation position and orientation of the second micro switch 65 are changed, and the structures of the base 61 and the cover plate 62 are also adjusted accordingly to accommodate the adjusted second micro switch 65.

[0203] like Figure 17-19As shown, in this embodiment, a second extension 617 is provided on the extension 613 on one side of the base 61. The second extension 617 is provided with a second mounting post 618 for mounting a second micro switch 65. The first micro switch 65 is fixed to the second mounting post 618. Simultaneously, the original structure for mounting the second micro switch 65 on the cover plate 62 is removed. The trigger rods of the first micro switch 64 and the second micro switch 65 are vertically arranged, as shown... Figure 20 As shown, the reset structure 32 has a raised trigger plate 323 on the side of its reset plate 321. The trigger plate 323 is inclined to the reset plate 321. The reset plate 321 and the trigger plate 323 are used to trigger the first micro switch 64 and the second micro switch 65, respectively. After the trigger plate 323 is raised, it is closer to the second micro switch 65, which facilitates pushing the trigger rod on the second micro switch 65. Preferably, as Figure 18 As shown, a raised mounting plate 619 is provided on the partition plate 612 on the side away from the extension 613 in the base 61. The mounting plate 619 is provided with a second buckle 610, which is limited and connected to the device housing 100.
