Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of circuit breakers, and in particular to a reset device and a circuit breaker. BACKGROUND

[0002] The circuit breaker includes an energy storage system and a switching system. The energy storage system needs to be linked with the switching system so that the energy storage system can perform energy storage actions according to actions of the switching system. The energy storage system includes a reset lever, and the switching system includes a lever. The actions of the switching system affect the actions of the lever, and the storage and release of energy in the energy storage system affect the actions of the reset lever. Therefore, a connection between the lever and the reset lever can be established, and torque can be transmitted through the connection, thereby realizing the linkage between the switching system and the energy storage system.

[0003] In related technologies, the reset lever and the lever are far apart, so that the reset lever and the lever both need to increase the structural length to realize the connection relationship therebetween, thereby causing the torque transmitted between the reset lever and the lever to be unevenly distributed on the overlong connection structure, affecting the structural strength of the reset lever and the lever and the stability of transmission between the reset lever and the lever, and further affecting the long-term service life of the circuit breaker. SUMMARY

[0004] The present application provides a reset device and a circuit breaker, which reduces the structural length of the lever and the reset lever, avoids the torque transmitted between the reset lever and the lever from being unevenly distributed on the overlong connection structure, ensures the structural strength of the reset lever and the lever and the connection stability, and thereby improves the long-term service life of the circuit breaker.

[0005] In a first aspect, the present application provides a reset device applied to a circuit breaker. The reset device includes a lever, a reset lever, and a transmission module. The lever is connected in a switching system of the circuit breaker. The reset lever is connected in an energy storage system of the circuit breaker. The transmission module is located between the reset lever and the lever. The transmission module includes a guide and a moving piece. The guide is fixed in the circuit breaker. The moving piece is connected to the guide. The guide provides a sliding track for the moving piece, and the moving piece slides along the sliding track. A first end of the sliding track is close to the lever and located on an action track of the lever. When the moving piece is located at the first end, the lever abuts against the moving piece during the action process and drives the moving piece to slide to a second end of the sliding track. The first end and the second end are two ends arranged oppositely. An end portion of the reset lever is located between the first end and the second end. When the moving piece slides to the second end, the moving piece abuts against the end portion and continues to slide, and is used to drive the reset lever to perform a reset action.

[0006] According to the description of the first aspect, the reset device effectively avoids the problem of excessively long structure caused by the direct long-distance connection between the lever and the reset rod by introducing the transmission module therebetween. The guide member in the transmission module provides the action member with an accurate sliding track, ensuring the uniformity and stability of torque transmission, thereby enhancing the transmission efficiency and the structural strength of the device. Thus, after the opening and closing actions of the circuit breaker, the reset action of the energy storage system can be reliably driven, improving the long-term service life and operation reliability of the circuit breaker.

[0007] In a possible design, the transmission module includes an elastic member, a torque input end of which is connected with the guide member. A torque output end of the elastic member is connected with the action member. When the action member slides toward the second end, the elastic member starts to accumulate reset potential energy. When the lever withdraws the abutment with the action member, the reset potential energy of the elastic member is transmitted to the action member through the torque output end, so that the action member returns to the first end in the opposite direction of the sliding track.

[0008] Based on the description of the above embodiment, the introduction of the elastic member in the transmission module enables the action member to automatically return to its initial position (the first end) after completing the reset action of the reset rod. Specifically, when the lever pushes the action member to slide toward the second end of the sliding track during the action process, the elastic member is stretched or compressed, thereby accumulating reset potential energy. Once the lever withdraws the abutment with the action member, the potential energy stored in the elastic member is transmitted to the action member through the torque output end, driving the action member to automatically return to the first end in the opposite direction of the sliding track. This automatic return mechanism avoids the action member staying at the second end, solves the problem that the action member cannot automatically reset, and thus ensures that the reset device can be efficiently and reliably reused, significantly improving the operation stability and long-term service life of the circuit breaker opening and closing system.

[0009] In a possible design, the transmission module includes a limiting unit. The limiting unit includes a limiting member and a limited member. The limiting member is arranged on the guide member. The limited member is arranged on the action member. The limited member is adapted to the limiting member, and is used to limit the action of the action member in the first direction and the second direction. The first direction is perpendicular to the second direction, and both the first direction and the second direction are perpendicular to the sliding direction of the action member.

[0010] Based on the description of the above embodiment, the limiting unit is introduced into the transmission module, which is composed of the limiting member arranged on the guide member and the limited member arranged on the action member, and the two are adapted to each other. This design can effectively limit the action of the action member in the first direction and the second direction, which are both perpendicular to the sliding direction of the action member, avoiding the shaking of the limited member in the first direction or the second direction, which may cause unstable transmission of the transmission module, thereby significantly improving the accuracy and reliability of torque transmission, and further ensuring the stability of the connection and transmission between the reset rod and the lever.

[0011] In a possible design, the guide member is a plate structure. The plate structure includes a top end and a bottom end oppositely arranged along a first direction, and the bottom end is fixedly connected in the circuit breaker. The plate structure includes a first structure surface and a second structure surface oppositely arranged along a second direction. The plate structure includes two end surfaces oppositely arranged along a third direction. The third direction is the sliding direction of the action member, and a line connecting the two end surfaces forms at least part of the sliding track.

[0012] The action member is a concave-shaped structure composed of a first side plate, a second side plate, and a connecting plate. The first side plate and the second side plate are oppositely arranged along the second direction. The connecting plate is arranged along the first direction and is connected to the first side plate and the second side plate. The plate structure is nested in the groove of the concave-shaped structure, so that the plate structure is located between the first side plate and the second side plate.

[0013] When the plate structure is nested in the groove, the top end faces the connecting plate, the first structure surface faces the first side plate, and the second structure surface faces the second side plate. There is a gap between the top end and the connecting plate, a gap between the first structure surface and the first side plate, and a gap between the second structure surface and the second side plate.

[0014] Based on the description of the above embodiment, the guide member adopts a plate structure and is nested with the action member of the concave-shaped structure, while precise gaps are reserved between the key contact surfaces. This design enables the action member to be stably guided by the plate structure during sliding, thereby improving the stability of the connection and transmission between the lever and the reset rod. At the same time, the existence of the gap avoids direct friction between the guide member and the action member, greatly reduces the sliding resistance, and ensures the smoothness and reliability of the reset action.

[0015] In a possible design, the limiting member includes a first limiting structure. The first limiting structure is a slot hole penetrating through the plate structure along the second direction. The slot hole is opened along the third direction, and the size of the slot hole in the third direction is greater than or equal to the length of the sliding track. The limited member includes a first limited structure. The first limited structure includes two first circular holes respectively opened on the first side plate and the second side plate. A fastening bolt is simultaneously threaded in the slot hole and the first circular hole, for limiting the movement of the action member in the axial direction of the fastening bolt. The axial direction is the second direction.

[0016] Based on the above description of the embodiments, in the transmission module, the limiting piece cooperates with the first limiting structure of the limited piece through the first limiting structure to achieve accurate limitation of the action piece in the second direction. Specifically, the slot hole penetrating the plate-shaped structure along the second direction is opened along the third direction and has a size greater than or equal to the length of the sliding track, which provides a channel for the fastening bolt to slide freely in the third direction while being constrained in the second direction. The fastening bolt is arranged in the first circular hole on both sides of the slot hole and the action piece, and the axis direction is consistent with the second direction, so that during the entire sliding process of the action piece, the lateral deviation of the action piece in the second direction is effectively prevented through the rigid connection of the bolt. This design significantly improves the accuracy and stability of the sliding track of the action piece, avoids the jamming, wear or failure of the transmission module caused by lateral deviation, and thus improves the overall reliability and service life of the reset device.

[0017] In a possible design, the limiting piece includes a second limiting structure. The second limiting structure includes abutting blocks and pressing blocks spaced apart along the first direction. The abutting blocks are fixedly connected to the first structure surface and / or the second structure surface, and the abutting blocks protrude from the first structure surface and / or the second structure surface along the second direction. The distance by which the abutting blocks protrude from the first structure surface is less than the gap between the first structure surface and the first side plate. And / or, the distance by which the abutting blocks protrude from the second structure surface is less than the gap between the second structure surface and the second side plate. The pressing blocks are detachably connected to the first structure surface and / or the second structure surface, and the pressing blocks protrude from the first structure surface and / or the second structure surface along the second direction. The distance by which the pressing blocks protrude from the first structure surface is less than the gap between the first structure surface and the first side plate. And / or, the distance by which the pressing blocks protrude from the second structure surface is less than the gap between the second structure surface and the second side plate.

[0018] The limited piece includes a second limiting structure. The second limiting structure includes a clamping block arranged along the second direction. The clamping block is arranged on one side of the first side plate facing the first structure surface. And / or, the clamping block is arranged on one side of the second side plate facing the second structure surface. When the plate-shaped structure is nested in the groove, the abutting blocks abut the upper surface of the clamping block along the first direction, and the pressing blocks support the lower surface of the clamping block along the first direction. Furthermore, one end of the clamping block facing the first structure surface is in contact with the first structure surface. And / or, one end of the clamping block facing the second structure surface is in contact with the second structure surface.

[0019] Based on the description of the above embodiments, the second limiting structure in this application includes abutment blocks and pressing blocks spaced apart along the first direction, and works in conjunction with the second limiting structure (i.e., snap-fit ​​block) on the actuating member. When the plate-like structure is nested in the groove, the abutment blocks abut against the upper surface of the snap-fit ​​block from above, and the pressing blocks support the lower surface of the snap-fit ​​block from below, thereby forming a stable upper and lower clamping limit on the actuating member in the first direction. At the same time, the end of the snap-fit ​​block facing the structural surface fits against the structural surface, further limiting the lateral displacement of the actuating member in the second direction. This multi-dimensional precise limiting mechanism effectively solves the problem of the actuating member shifting or loosening during sliding, ensuring that the actuating member always stays on the predetermined sliding trajectory during sliding, greatly improving the accuracy and stability of the transmission between the reset rod and the lever, thereby ensuring the reliability and long service life of the linkage action of the circuit breaker opening and closing system and the energy storage system.

[0020] In one possible design, the limiting member includes a third limiting structure. The third limiting structure is a boss structure disposed on the first structural surface and / or the second structural surface. The boss structure protrudes from the first structural surface and / or the second structural surface along a second direction. The distance by which the boss structure protrudes from the first structural surface is greater than the gap between the first structural surface and the first side plate. And / or, the distance by which the boss structure protrudes from the second structural surface is greater than the gap between the second structural surface and the second side plate.

[0021] The restraining component includes a third restraining structure. The third restraining structure is the bottom surface of the first side plate and / or the second side plate. Specifically, the bottom surface of the first side plate is the side of the first side plate that is away from the connecting plate in the first direction, and the bottom surface of the second side plate is the side of the second side plate that is away from the connecting plate in the first direction. When the plate-like structure is nested within the groove, the third restraining component abuts against the third restraining component in the first direction, thereby restricting the movement of the actuating component in the first direction and maintaining the gap between the top end and the connecting plate.

[0022] Based on the description of the above embodiments, the limiting member may further include a third limiting structure, which is a boss structure disposed on the first structural surface and / or the second structural surface. This boss protrudes from the first structural surface and / or the second structural surface along the second direction, and the protrusion distance is greater than the gap between the first structural surface and the first side plate and / or between the second structural surface and the second side plate. Simultaneously, the limiting member includes a third limiting structure, which is the bottom surface of the first side plate and / or the second side plate, i.e., the side of the first side plate and / or the second side plate away from the connecting plate in the first direction. When the plate-like structure is nested in the groove, the boss structure of the third limiting member can abut against the bottom surface of the third limiting member in the first direction, effectively limiting the movement of the actuator in the first direction. This prevents changes in the gap between the top end and the connecting plate due to vertical displacement during sliding, avoiding problems such as actuator wobbling, jamming, or increased friction caused by excessively large or small gaps. This significantly improves the smoothness and reliability of the actuator sliding along the sliding trajectory, thereby ensuring the accuracy of the reset action and the long-term stability of the circuit breaker.

[0023] In one possible design, the actuator includes an end plate positioned along a third direction. When the plate-like structure is nested within the groove, the end plate abuts against the end face, maintaining the actuator in a position along the third direction between the first and second ends.

[0024] Based on the description of the above embodiments, this application, by providing an end plate along a third direction on the actuator, and having it abut against the end face of the guide when the plate-like structure is nested in the groove, precisely maintains the position of the actuator between the first and second ends, preventing the actuator from shifting position or exceeding the predetermined range during sliding. This avoids the actuator from slipping out of the lever's trajectory due to excessive sliding or positional shift, thus preventing transmission jamming or functional failure of the reset device. Furthermore, the actuator's location between the first and second ends ensures it remains within the effective transmission range, providing a stable foundation for subsequent reset actions. Therefore, the transmission stability of the transmission module is significantly improved, and the accuracy of the reset action is guaranteed, thereby enhancing the reliability of the linkage between the circuit breaker energy storage system and the opening and closing system, effectively solving the transmission instability problem caused by actuator position loss in the prior art.

[0025] In one possible design, the elastic element is a tension spring. The torque input end of the tension spring is connected to the guide member near the lever. The torque output end of the tension spring is connected to the actuating member near the reset lever. Alternatively, the elastic element is a compression spring. The torque output end of the compression spring is connected to the guide member near the lever, and the torque input end of the compression spring is connected to the actuating member near the lever. Alternatively, the torque output end of the compression spring is connected to the guide member near the reset lever, and the torque input end of the compression spring is connected to the actuating member near the reset lever.

[0026] Based on the description of the above embodiments, this application optimizes the storage and release process of potential energy in the reset device by specifically defining the type and connection position of the elastic element, thereby solving the problems of low reset efficiency and reliability caused by improper selection of the elastic element. Specifically, when the elastic element is a tension spring, the torque output end of the tension spring is connected to the side of the guide near the lever, and the torque input end is connected to the side of the actuating element near the reset rod. This connection method ensures that the tension spring is stretched and stores potential energy during the sliding process of the actuating element, and efficiently transmits torque to the actuating element when released, avoiding energy loss. Alternatively, when the elastic element is a compression spring, the torque output end and input end of the compression spring can be flexibly connected to the side of the guide near the lever or reset rod and the side of the actuating element near the lever or reset rod. This design adapts to different spatial layouts, allowing the compression spring to store energy during compression and release it stably during the reset action, improving the overall transmission accuracy. These features together enhance the stability and reliability of the reset action, enabling the reset device to maintain efficient and stable performance during long-term operation.

[0027] Secondly, this application provides a circuit breaker, including a closing / opening system, an energy storage system, and a reset device as described in any of the above embodiments. The reset device links the closing / opening system and the energy storage system, enabling the energy storage system to perform energy storage operations according to the actions of the closing / opening system.

[0028] The circuit breaker provided in the second aspect above has the same beneficial effects as the first aspect and the various possible implementations of the first aspect, and will not be repeated here. Attached Figure Description

Detailed Implementation

[0047] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0049] The terms "comprising" and "having," and any variations thereof, used in the specification, claims, and drawings of this application are intended to cover without excluding other meanings. The words "a" or "an" do not exclude the existence of multiple entities.

[0050] The term "embodiment" as used herein means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of the phrase "embodiment" in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0051] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0052] The directional terms appearing in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of this application. For example, in the description of this application, terms such as "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the figures. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0053] Furthermore, the descriptions of directions such as the X direction, Y direction, and Z direction used to explain the operation and construction of the components in this embodiment are not absolute but relative. Although these directions are appropriate when the components are in the positions shown in the figure, they should be interpreted differently when these positions change to correspond to the changes.

Signal connection can refer not only to signal connection through a circuit but also to signal connection through a media, such as radio waves. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0057] The circuit breaker includes an energy storage system and a closing / opening system. The energy storage system needs to be linked with the closing / opening system to enable it to store energy in response to the actions of the closing / opening system. The energy storage system includes a reset lever, and the closing / opening system includes a lever. The actions of the closing / opening system affect the actions of the lever, and the storage and release of energy in the energy storage system affects the actions of the reset lever. Therefore, by establishing a connection between the lever and the reset lever, and transmitting torque through this connection, the linkage between the closing / opening system and the energy storage system can be achieved.

[0058] Specifically, the operation of the circuit breaker system includes closing, tripping, and opening actions. After a tripping action, the reset lever in the energy storage system pops out, releasing energy. At this point, the handle in the circuit breaker system is in the tripped position. When the circuit breaker system needs to close after a tripping action, the handle in the tripped position needs to move to the opening position. The opening position refers to the position of the handle after the circuit breaker system has performed an opening action. During the movement of the handle from the tripped position to the opening position, the lever structure connected to the handle causes the reset lever to return to its original position, allowing the energy storage system to re-store energy, enabling the circuit breaker system to perform a closing action.

[0059] In related technologies, the distance between the reset rod and the lever is relatively large, and the reset rod and the lever are directly connected to achieve the reset of the reset rod. This requires both the reset rod and the lever to increase their structural length to achieve the connection relationship. As a result, the torque transmitted between the reset rod and the lever is unevenly distributed on the excessively long connection structure, which affects the stability of the transmission between the reset rod and the lever, as well as the structural strength of the reset rod and the lever, and thus affects the long-term service life of the circuit breaker.

[0060] Based on this, this application provides a reset device and a circuit breaker. By setting a transmission module between the lever and the reset rod, the structural length of the lever and the reset rod is reduced, avoiding uneven distribution of the torque transmitted between the reset rod and the lever on an excessively long connection structure. This ensures the structural strength and connection stability of the reset rod and the lever, thereby improving the long-term service life of the circuit breaker. The following is in conjunction with... Figures 1-16 Provide a detailed description.

[0061] Firstly, such as Figure 1 and Figure 2 As shown, this application provides a reset device 1000 applied to a circuit breaker. The reset device 1000 includes a lever 100, a reset rod 200, and a transmission module 300. The lever 100 is connected to the circuit breaker's opening and closing system. The reset rod 200 is connected to the circuit breaker's energy storage system. The transmission module 300 is located between the reset rod 200 and the lever 100. The transmission module 300 includes a guide 1 and an actuating element 2. The guide 1 is fixed in the circuit breaker. The actuating element 2 is connected to the guide 1. The guide 1 provides a sliding trajectory for the actuating element 2, causing the actuating element 2 to slide along the sliding trajectory. The first end La of the sliding trajectory is close to the lever 100 and located on the actuating trajectory of the lever 100. When the actuating element 2 is located at the first end La, the lever 100 abuts against the actuating element 2 during operation, driving the actuating element 2 to slide towards the second end Lb of the sliding trajectory. The first end La and the second end Lb are opposite ends. The end of the reset rod 200 is located between the first end La and the second end Lb. When the actuator 2 slides toward the second end Lb, the actuator 2 abuts against the end and continues to slide, which drives the reset rod 200 to perform a reset action.

[0062] The reset device 1000 is a mechanical structure used to restore a specific component in a circuit breaker to its initial position. Its function is to ensure that the circuit breaker is ready for the next operation after completing a specific operation, such as enabling an energy storage system to restore energy.

[0063] A circuit breaker is a switching device that plays a protective role in a circuit. When a circuit experiences overload, short circuit, or other faults, the circuit breaker can automatically disconnect the circuit. In this embodiment, the reset device 1000 is applied inside the circuit breaker to achieve linkage between its energy storage system and its opening and closing system.

[0064] Lever 100 is a key component in the circuit breaker's opening and closing system. It receives the operating commands from the system via a mechanical connection and transmits torque. The trajectory of lever 100 is the path it follows during the opening and closing process. Specifically, lever 100 can be directly welded to a moving part of the opening and closing system, or fixedly connected by bolts, rivets, or other means. For example, one end of lever 100 can be connected to a handle in the opening and closing system via a pin; when the handle is moved, lever 100 swings accordingly.

[0065] The reset lever 200 is a component of the circuit breaker energy storage system, and its operation is closely related to the energy storage and release of the system. When the energy storage system releases energy, the reset lever 200 is usually in an extended state and needs to be reset to its original position so that the energy storage system can re-store energy. Specifically, the reset lever 200 can be fixed to a movable part of the energy storage system, for example, by means of a snap-fit ​​or adhesive connection. Alternatively, one end of the reset lever 200 can be inserted into a hole in the energy storage system and connected by friction or a simple limiting structure, allowing it to extend, retract, or pop out as the energy storage system's state changes.

[0066] In this embodiment, the transmission module 300 serves as an intermediary structure connecting the lever 100 and the reset rod 200. Its function is to receive the movement of the lever 100 and convert it into the action of driving the reset rod 200 to reset. The transmission module 300 is designed to optimize torque transmission and reduce the structural length of the lever 100 and the reset rod 200. Specifically, the transmission module 300 can be placed in a specific space inside the circuit breaker, for example, fixed to the circuit breaker housing by a bracket or base. Its position is configured to simultaneously achieve effective mechanical contact with both the lever 100 and the reset rod 200 to transmit the action.

[0067] The guide component 1 is a fixed part in the transmission module 300, fixed inside the circuit breaker, providing a preset sliding trajectory for the actuator 2. The guide component 1 ensures controlled movement of the actuator 2 in a specific direction, thereby guaranteeing the stability and accuracy of the transmission process. Specifically, as... Figure 2 As shown, the guide 1 can be part of the support in the circuit breaker, thereby reducing the number of parts in the circuit breaker and reducing the production cost of the circuit breaker.

[0068] In this design, the actuating element 2 is a movable component in the transmission module 300, which is connected to the guide element 1 and slides along the sliding trajectory provided by the guide element 1. The actuating element 2 moves under the drive of the lever 100, thereby driving the reset rod 200 to reset.

[0069] The sliding trajectory is the movement path set by the guide 1 for the actuator 2, along which the actuator 2 slides linearly or curvilinearly. The setting of the sliding trajectory ensures the direction and range of motion of the actuator 2, and is crucial for achieving precise transmission.

[0070] The first end La and the second end Lb of the sliding trajectory can be located at the starting point and the ending point of the sliding trajectory, respectively, for example, at the two ends of a straight sliding trajectory. They are spatially far apart, defining the range of motion of the actuator 2.

[0071] Specifically, the first end La is a specific position on the sliding trajectory, which is set close to the lever 100 and located on the movement trajectory of the lever 100. When the actuator 2 is located at this end, it can directly contact the lever 100 and receive its driving force.

[0072] When the actuator 2 is at the first end La, the lever 100 will make physical contact with the actuator 2 during the operation. This contact allows the lever 100 to directly push the side of the actuator 2, causing it to move along a sliding trajectory. For example, the end of the lever 100 near the actuator 2 can be a flat surface, which, when it swings, directly pushes the side of the actuator 2 facing the lever 100, causing the actuator 2 to begin sliding.

[0073] Specifically, the second end Lb is another specific position on the sliding trajectory, which is set opposite to the first end La. Driven by the lever 100, the actuator 2 slides from the first end La to the second end Lb, and abuts against the end of the reset rod 200 during the sliding process, thereby realizing the reset of the reset rod 200.

[0074] When the actuator 2 slides towards the second end Lb, it will contact the end of the reset rod 200. This contact allows one side or a protrusion of the actuator 2 to push against the end of the reset rod 200, causing it to move in a preset direction, thereby resetting the reset rod 200. For example, the actuator 2 may have an inclined surface, which gradually pushes against the end of the reset rod 200 as it slides, causing it to slowly reset.

[0075] Specifically, the end of the reset rod 200 can be placed between the first end La and the second end Lb, that is, in the middle area of ​​the sliding trajectory of the actuator 2, for example, on the straight segment of the sliding trajectory. When the actuator 2 slides from the first end La to the second end Lb, it will pass through the position where the end of the reset rod 200 is located and make contact with it.

[0076] According to the description in the first aspect, the reset device 1000 effectively avoids the problem of excessive structural length caused by a direct long-distance connection between the lever 100 and the reset rod 200 by introducing a transmission module 300 between them. The guide member 1 in the transmission module 300 provides a precise sliding trajectory for the actuating member 2, ensuring the uniformity and stability of torque transmission, thereby enhancing transmission efficiency and the structural strength of the device. Therefore, after the circuit breaker performs opening and closing actions, the reset action of the energy storage system can be reliably driven, improving the long-term service life and operational reliability of the circuit breaker.

[0077] In some embodiments of this application, a transmission module 300 is proposed to transmit torque and drive the reset rod 200 to reset. However, in its implementation, the actuator 2 cannot automatically return to the first end La after sliding to the second end Lb, which affects the repeated use of the device.

[0078] Based on this, in some embodiments, such as Figure 1 As shown, the transmission module 300 includes an elastic element 3, the torque input end 3a of which is connected to the guide element 1. The torque output end 3b of the elastic element 3 is connected to the actuating element 2. When the actuating element 2 slides towards the second end Lb, the elastic element 3 begins to accumulate reset potential energy. When the lever 100 removes its contact with the actuating element 2, the reset potential energy of the elastic element 3 is transmitted to the actuating element 2 through the torque output end 3b, causing the actuating element 2 to return to the first end La in the opposite direction of the sliding trajectory.

[0079] Among them, the elastic element 3 is a mechanical component that can deform under the action of external force and return to its original shape after the external force is removed. It can store and release potential energy during the deformation process. Specifically, the elastic element 3 can be a spring, such as a tension spring 31, a compression spring 32, etc., which stores and releases energy through its extension or compression.

[0080] The torque input end 3a of the elastic element 3 is connected to the guide element 1 to ensure that the elastic element 3 has a stable fixed point when accumulating potential energy, so that it can be effectively stretched or compressed to store energy. Specifically, the torque input end 3a of the elastic element 3 can be firmly fixed to the guide element 1 by means of bolts, rivets or welding, or it can be detachably connected to the guide element 1 by means of buckles, hooks or other means, which facilitates installation and maintenance.

[0081] The torque output end 3b of the elastic element 3 is connected to the actuating element 2, and is used to directly transfer the potential energy stored in the elastic element 3 to the actuating element 2, driving the actuating element 2 to move in the opposite direction of the sliding trajectory. The torque output end 3b of the elastic element 3 can be connected to a specific structure on the actuating element 2 by means of a pin, connecting rod or direct hook, or can be integrated with the actuating element 2 by means of bonding or embedding, to ensure the directness of torque transmission.

[0082] Specifically, when the actuator 2 slides towards the second end Lb, the elastic element 3 begins to accumulate restoring potential energy. This means that when the lever 100 pushes the actuator 2 from the first end La to the second end Lb during its operation, the length or shape of the elastic element 3 changes; for example, the tension spring 31 is stretched and the compression spring 32 is compressed, thereby converting mechanical energy into elastic potential energy and storing it to prepare for subsequent automatic return. When the lever 100 removes its contact with the actuator 2, the restoring potential energy of the elastic element 3 is transmitted to the actuator 2 through the torque output end 3b, causing the actuator 2 to return to the first end La in the opposite direction of the sliding trajectory. Once the lever 100 is no longer in contact with the actuator 2, the potential energy stored in the elastic element 3 is released, applying a restoring force to the actuator 2 through its torque output end 3b. This restoring force will drive the actuator 2 to slide in the opposite direction of the sliding trajectory, i.e., from the second end Lb to the first end La, until it returns to the first end La.

[0083] According to the description of the above embodiment, an elastic element 3 is introduced into the transmission module 300 so that the actuator 2 can automatically return to its initial position (first end La) after completing the reset action of the reset lever 200. Specifically, when the lever 100 pushes the actuator 2 to slide towards the second end Lb of the sliding trajectory during the operation, the elastic element 3 is stretched or compressed, thereby accumulating reset potential energy. Once the lever 100 removes its contact with the actuator 2, the potential energy stored in the elastic element 3 is transmitted to the actuator 2 through its torque output end 3b, driving the actuator 2 to automatically return to the first end La in the opposite direction of the sliding trajectory. This automatic return mechanism avoids the actuator 2 from staying at the second end Lb, solves the problem of the actuator 2 not being able to automatically reset, and thus ensures that the reset device 1000 can be reused efficiently and reliably, significantly improving the operational stability and long-term service life of the circuit breaker opening and closing system.

[0084] In some embodiments of this application, a transmission module 300 is proposed to transmit torque and realize the sliding of the actuator 2. However, during its implementation, the actuator 2 may deviate in other directions perpendicular to the sliding direction when sliding, resulting in transmission instability and reduced accuracy.

[0085] Based on this, in some embodiments, the transmission module 300 includes a limiting unit. The limiting unit includes a limiting member and a restricting member. The limiting member is disposed on the guide member 1. The restricting member is disposed on the actuating member 2. The restricting member is adapted to the limiting member to limit the movement of the actuating member 2 in a first direction X and a second direction Y. The first direction X is perpendicular to the second direction Y, and both the first direction X and the second direction Y are perpendicular to the sliding direction of the actuating member 2.

[0086] The limiting unit is a structure or component used to constrain the range of motion of a part. Its main function is to ensure that the actuator 2 runs stably on a predetermined sliding trajectory and prevent it from deviating in an unexpected direction. This unit can be implemented by various mechanical structures, such as through the cooperation of a guide rail and a slider, the cooperation of a pin and a slot, or the cooperation of a protrusion and a groove 24, to provide physical restraint.

[0087] In this context, the limiting element is a component that is relatively fixed or serves as a reference point within the limiting unit. It is typically mounted on the guide element 1, acting as a boundary or guide for the movement of the actuator 2. The limiting element can be implemented in various ways, including one or more protrusions, edges, channels, holes, or guide surfaces, whose shape and position match the limiting element to collectively constrain the actuator 2. For example, the limiting element can be designed as one or more flanges on the guide element 1, or as a limiting groove formed on the guide element 1.

[0088] The limiting component is a part in the limiting unit that is connected to and moves with the actuating component 2. It cooperates with the limiting component to jointly perform the function of limiting the movement of the actuating component 2. The structure of the limiting component may include, but is not limited to, a pin, a slider, a flange, a locking block, or a specific structural surface, allowing it to form a tight or clearance fit with the limiting component, thereby preventing or guiding the movement of the actuating component 2 in a specific direction. For example, the limiting component may be designed as one or more grooves 24 or protrusions on the actuating component 2 that mate with the flange or limiting groove of the limiting component.

[0089] Specifically, the fitting between the limiting component and the locating component refers to the matching relationship between the limiting component and the locating component in terms of structure, size, and shape. This matching ensures that the two can interact effectively, thereby achieving precise restriction of the moving component 2. The fitting relationship can be a tight fit to eliminate gaps, or a sliding fit with a certain gap to allow free movement of the moving component 2 in the sliding direction while restricting its offset in other directions.

[0090] Among them, such as Figure 2 As shown, the first direction X and the second direction Y represent the directions of motion in two planes orthogonal to the sliding direction. By restricting the movement in these two directions, any displacement of the actuator 2 from the sliding trajectory during the sliding process can be completely prevented, thereby ensuring the linearity and stability of the transmission.

[0091] As described in the above embodiment, a limiting unit is introduced into the transmission module 300. This limiting unit consists of a limiting member disposed on the guide member 1 and a limiting member disposed on the actuating member 2, and the two are mutually compatible. This design can effectively limit the movement of the actuating member 2 in the first direction X and the second direction Y, which are perpendicular to the sliding direction of the actuating member 2. This avoids the limiting member from wobbling in the first direction X or the second direction Y, which would cause instability in the transmission module 300, thereby significantly improving the accuracy and reliability of torque transmission, and thus ensuring the stability of the connection and transmission between the reset rod 200 and the lever 100.

[0092] Next, this application will describe in detail the specific structure of the guide member 1 and the action member 2 and the connection method between them, in conjunction with some specific embodiments.

[0093] In some specific implementations, such as Figure 3 and Figure 4 As shown, the guide member 1 is a plate-like structure. The plate-like structure includes a top end 11 and a bottom end 12 arranged opposite each other along a first direction X, with the bottom end 12 fixedly connected to the circuit breaker. The plate-like structure includes a first structural surface 13 and a second structural surface 14 arranged opposite each other along a second direction Y. The plate-like structure includes two end faces 15 arranged opposite each other along a third direction Z. The third direction Z is the sliding direction of the actuating member 2, and the line connecting the two end faces 15 forms at least a partial sliding trajectory.

[0094] like Figure 5 and Figure 6 As shown, the actuating component 2 is a U-shaped structure composed of a first side plate 21, a second side plate 22, and a connecting plate 23. The first side plate 21 and the second side plate 22 are arranged opposite each other along the second direction Y. The connecting plate 23 is arranged along the first direction X and is connected to both the first side plate 21 and the second side plate 22. The plate-like structure is nested within the groove 24 of the U-shaped structure, so that the plate-like structure is located between the first side plate 21 and the second side plate 22.

[0095] When the plate-like structure is nested within the groove 24, the top end 11 faces the connecting plate 23, the first structural surface 13 faces the first side plate 21, and the second structural surface 14 faces the second side plate 22. There is a gap between the top end 11 and the connecting plate 23, a gap between the first structural surface 13 and the first side plate 21, and a gap between the second structural surface 14 and the second side plate 22.

[0096] The plate-like structure includes a top end 11 and a bottom end 12 positioned opposite each other along a first direction X, with the bottom end 12 fixedly connected within the circuit breaker. The top end 11 and bottom end 12 define the height of the plate-like structure in the first direction X, while the fixed connection of the bottom end 12 ensures the stable installation of the guide member 1 inside the circuit breaker. This fixed connection can be achieved through various methods such as bolting, welding, riveting, snap-fitting, or integral molding, aiming to prevent displacement or wobbling of the guide member 1 during the sliding of the actuating member 2, thereby ensuring the stability of the sliding trajectory.

[0097] In addition, the plate-like structure also includes a first structural surface 13 and a second structural surface 14 arranged opposite to each other along the second direction Y. These structural surfaces are the two main sides of the plate-like structure in the second direction Y, and they can be designed as smooth planes or have specific textures or coatings to optimize friction performance. The first structural surface 13 and the second structural surface 14 are mainly used to provide lateral guidance and support for the actuator 2, effectively limiting the offset of the actuator 2 in the second direction Y, and ensuring that it remains stable in the width direction of the sliding trajectory.

[0098] Meanwhile, the plate-like structure also includes two end faces 15 arranged opposite each other along a third direction Z, wherein the third direction Z is the sliding direction of the actuator 2, and the line connecting the two end faces 15 forms at least part of the sliding trajectory. When the line connecting the two end faces 15 is the entire sliding trajectory of the actuator 2, the aforementioned end faces 15 can directly define the sliding range of the actuator 2.

[0099] Corresponding to the guide member 1 in the above specific embodiment, the actuating member 2 is a U-shaped structure composed of a first side plate 21, a second side plate 22, and a connecting plate 23. The U-shaped structure is a shape with a groove 24, typically consisting of two parallel side plates and a connecting plate 23 connecting them. This structure can be made from sheet metal or engineering plastics, such as U-shaped channel steel, C-shaped aluminum profiles, or injection-molded plastic parts, through methods such as stamping, bending, welding, or integral molding. This design aims to form a groove 24 capable of accommodating the guide member 1, achieving coverage and guidance of the guide member 1, while providing sufficient structural strength to withstand the actuating force transmitted by the transmission module 300.

[0100] Specifically, the first side plate 21 and the second side plate 22 are arranged opposite each other along the second direction Y, and the connecting plate 23 is arranged along the first direction X and is connected to both the first side plate 21 and the second side plate 22. The connection between the side plate and the connecting plate 23 can be a right-angle connection, a rounded corner connection, or reinforced by reinforcing ribs to ensure that it can effectively cover and guide the guide member 1.

[0101] In practical applications, the plate-like structure is nested within the groove 24 of the U-shaped structure, positioning the plate-like structure between the first side plate 21 and the second side plate 22. This nesting relationship is the core mechanism for guiding and limiting, allowing the actuating element 2 to tightly enclose the guide element 1, thereby providing stable guidance during sliding. During nesting, the plate-like structure can be inserted from one end of the U-shaped structure, or the U-shaped structure can be fastened to the plate-like structure from above or the side.

[0102] Specifically, when the plate-like structure is nested within the groove 24, the top 11 faces the connecting plate 23, the first structural surface 13 faces the first side plate 21, and the second structural surface 14 faces the second side plate 22. This clear relative positional relationship ensures the correct alignment of the components, laying the foundation for subsequent gap setting and limiting functions, and avoiding poor sliding or jamming due to assembly errors. This alignment can be ensured through visual inspection during assembly or through mechanical limiting structures.

[0103] To further optimize sliding performance, gaps exist between the top end 11 and the connecting plate 23, between the first structural surface 13 and the first side plate 21, and between the second structural surface 14 and the second side plate 22. These gaps are crucial for reducing friction and ensuring smooth sliding. The dimensions of these gaps are typically controlled through precise machining tolerances; for example, they can be designed to be minute gaps of 0.1 mm to 0.5 mm. These gaps prevent excessive friction caused by direct contact between the guide 1 and the actuator 2 during sliding, while allowing for certain manufacturing tolerances and thermal expansion and contraction, thereby improving the stability and reliability of the sliding motion of the actuator 2.

[0104] As described in the above embodiment, the guide 1 adopts a plate-like structure and forms a nested fit with the U-shaped actuating member 2, while a precise gap is reserved between the key contact surfaces. This design allows the actuating member 2 to be stably guided by the plate-like structure during sliding, thereby improving the stability of the connection and transmission between the lever 100 and the reset rod 200. Simultaneously, the gap avoids direct friction between the guide 1 and the actuating member 2, significantly reducing sliding resistance and ensuring the smoothness and reliability of the reset action.

[0105] Next, based on the description of the guide member 1 and the action member 2 in the above embodiments, this application will specifically describe the structure and limiting method of the limiting member and the limiting member that can achieve the limiting in the first direction X and / or the second direction Y, in conjunction with the following three specific implementation methods.

[0106] Firstly, in some specific implementation methods, such as Figures 2-6 as well as Figures 7-11As shown, the limiting component includes a first limiting structure. The first limiting structure is a slotted hole 16 that penetrates the plate-like structure along the second direction Y. The slotted hole 16 is opened along the third direction Z, and the size of the slotted hole 16 in the third direction Z is greater than or equal to the length of the sliding trajectory. The limiting component includes a first limiting structure. The first limiting structure includes two first circular holes 25, which are respectively opened on the first side plate 21 and the second side plate 22. The fastening bolt 4 is simultaneously inserted into the slotted hole 16 and the first circular holes 25 to limit the movement of the moving component 2 in the axial direction of the fastening bolt 4. The axial direction is the second direction Y.

[0107] Among them, such as Figure 3 , Figure 4 as well as Figure 8 , Figure 9 As shown, the first limiting structure is a specific implementation of the limiting member, which is used at least to provide a limit on the actuator 2 in the second direction Y, so as to prevent the actuator 2 from undergoing undesirable lateral displacement during sliding.

[0108] The slotted hole 16 is a through hole with a specific length and direction, designed to allow the fastener to pass through and slide along its long axis. In this application, the slotted hole 16 penetrates the plate-like structure along the second direction Y, meaning that the opening direction of the hole is consistent with the second direction Y, and it penetrates the thickness of the plate-like structure. This design provides the fastener with a channel for constraint in the second direction Y, while allowing free sliding in the third direction Z. Specifically, the length direction of the slotted hole 16 is consistent with the sliding direction of the actuator 2 (i.e., the third direction Z), ensuring that the fastener can always move within the range of the slotted hole 16 during the entire sliding stroke of the actuator 2 along the sliding trajectory, without being hindered by insufficient hole length. At the same time, the dimension of the slotted hole 16 in the third direction Z is designed to be greater than or equal to the length of the sliding trajectory, which further ensures that the actuator 2 is effectively limited throughout the entire sliding range, thereby maintaining its positional stability in the second direction Y. For example, the length of the slot 16 can slightly exceed the actual length of the sliding track to provide some operating space; or, its length can be precisely matched with the length of the sliding track to achieve a more compact structural design.

[0109] Among them, such as Figure 5 , Figure 6 as well as Figure 10 , Figure 11 As shown, the first restricted structure is a specific implementation of the restricted component, used to work in conjunction with the first limiting structure (the hole 16) to achieve precise limiting of the action component 2 in the second direction Y.

[0110] Among them, such as 5 and Figure 10As shown, the first circular hole 25 is a circular through hole formed on the first side plate 21 and the second side plate 22 of the actuator 2. By symmetrically setting these two first circular holes 25 on both sides of the actuator 2, this symmetrical design helps to avoid problems such as tilting, jamming or wear caused by uneven force on one side during the sliding process of the actuator 2, thereby ensuring that the force distribution of the actuator 2 is more uniform when it is connected and constrained with the limiting member, so as to achieve a balanced and stable limiting effect.

[0111] Among them, such as Figure 2 and Figure 7 As shown, the fastening bolt 4, as a mechanical connector, serves the core function of connecting the plate-like structure to the actuator 2 and providing a crucial limiting function. When the fastening bolt 4 passes through both the slotted hole 16 on the plate-like structure and the first circular holes 25 on both sides of the actuator 2, it can form a rigid physical constraint in the second direction Y. For example, a common bolt with a nut can be used, and sufficient fastening force can be provided by tightening the nut; alternatively, a self-locking nut or washer can be used to enhance the reliability and vibration resistance of the connection.

[0112] Through the above technical solution, in the transmission module 300, the limiting member, through the synergistic action of the first limiting structure and the first limiting structure of the limiting member, achieves precise restriction of the actuating member 2 in the second direction Y. Specifically, the slotted hole 16 penetrating the plate-like structure along the second direction Y, with its opening along the third direction Z and a size greater than or equal to the length of the sliding trajectory, provides a channel for the fastening bolt 4 to slide freely in the third direction Z while being constrained in the second direction Y. The fastening bolt 4 is simultaneously inserted into the slotted hole 16 and the first circular holes 25 on both sides of the actuating member 2, with its axial direction aligned with the second direction Y. Thus, during the entire sliding process of the actuating member 2, the rigid connection of the bolt effectively prevents the actuating member 2 from lateral displacement in the second direction Y. This design significantly improves the accuracy and stability of the sliding trajectory of the actuating member 2, avoids jamming, wear, or failure of the transmission module 300 due to lateral displacement, and thereby improves the overall reliability and service life of the reset device 1000.

[0113] Secondly, in some other specific implementations, such as Figures 12-16As shown, the limiting member includes a second limiting structure. The second limiting structure includes abutment blocks 17 and pressing blocks 18 spaced apart along a first direction X. The two abutment blocks 17 are respectively fixedly connected to the first structural surface 13 and the second structural surface 14, and the abutment blocks 17 protrude from the first structural surface 13 / second structural surface 14 along a second direction Y. The distance by which the abutment blocks 17 protrude from the first structural surface 13 / second structural surface 14 is less than the gap between the first structural surface 13 / second structural surface 14 and the first side plate 21 / second side plate 22. The two pressing blocks 18 are respectively detachably connected to the first structural surface 13 and the second structural surface 14, and the pressing blocks 18 protrude from the first structural surface 13 / second structural surface 14 along a second direction Y. The distance by which the pressing blocks 18 protrude from the first structural surface 13 / second structural surface 14 is less than the gap between the first structural surface 13 / second structural surface 14 and the first side plate 21 / second side plate 22.

[0114] The confining component includes a second confining structure. The second confining structure includes two locking blocks 26 disposed along a second direction Y. One locking block 26 is disposed on the surface of the first side plate 21 facing the first structural surface 13. The other locking block 26 is disposed on the surface of the second side plate 22 facing the second structural surface 14. When the plate-like structure is nested within the groove 24, the abutment block 17 abuts against the upper surface of the locking block 26 along the first direction X, and the pressing block 18 supports the lower surface of the locking block 26 along the first direction X. Furthermore, one end of the locking block 26 facing the first structural surface 13 / second structural surface 14 is in contact with the first structural surface 13 / second structural surface 14.

[0115] Among them, such as Figures 13-14 As shown, the second limiting structure is another specific implementation of the limiting member, used to provide limiting for the actuating member 2 in the first direction X and the second direction Y, so as to prevent the actuating member 2 from undergoing undesirable displacement during sliding. Specifically, the second limiting structure may include abutment blocks 17 and pressing blocks 18 distributed at intervals along the first direction X.

[0116] The abutment block 17 and the clamping block 18 are the basic units constituting the second limiting structure. They are arranged in space along the first direction X (i.e., perpendicular to the sliding direction of the actuating member 2 and the second direction Y), thereby providing upper and lower limiting functions for the actuating member 2. These abutment blocks 17 and clamping blocks 18 can be integrally formed protruding structures, for example, formed by local thickening or plastic deformation on the guide member 1; or they can be independent block elements made of metal, high-strength plastic or composite material, and installed by mechanical fixing (such as screws, pins) or chemical bonding.

[0117] Specifically, the two abutting blocks 17 are fixedly connected to the first structural surface 13 and the second structural surface 14 respectively. Their function is to provide an upper limit for the actuator 2 and prevent the actuator 2 from moving upward in the first direction X.

[0118] Furthermore, the abutment block 17 protrudes along the second direction Y from the first structural surface 13 / second structural surface 14, and its protrusion distance is less than the gap between the first structural surface 13 / second structural surface 14 and the first side plate 21 / second side plate 22. This design ensures that the abutment block 17, while providing a limiting effect on the actuator 2, will not interfere with the first side plate 21 or the second side plate 22 of the actuator 2, thereby ensuring that the actuator 2 can slide smoothly along the sliding trajectory and reducing unnecessary friction and wear.

[0119] Specifically, the two clamping blocks 18 are detachably connected to the first structural surface 13 and the second structural surface 14, respectively. Their function is to provide lower limit and support for the actuator 2, preventing the actuator 2 from moving downward in the first direction X.

[0120] Furthermore, the clamping block 18 protrudes along the second direction Y from the first structural surface 13 / second structural surface 14, and its protrusion distance is less than the gap between the first structural surface 13 / second structural surface 14 and the first side plate 21 / second side plate 22. Similar to the abutment block 17, this limitation also ensures that the clamping block 18 provides a limiting function without interfering with the side plate of the actuator 2, thereby ensuring the smooth sliding of the actuator 2.

[0121] Among them, such as Figures 15-16 As shown, the second restrictive structure is another specific implementation of the restrictive component, used to work in conjunction with the second limiting structure (abutment block 17 and clamping block 18) to precisely limit the movement of the actuator 2 in the first direction X and the second direction Y. Specifically, the second restrictive structure may include two locking blocks 26 arranged along the second direction Y. The locking blocks 26 may be protrusions formed by stamping, bending or milling on the side plate of the actuator 2; or they may be individual block elements made of wear-resistant material and fixed to the side plate by welding, screws or adhesive.

[0122] When the plate-like structure is nested within the groove 24, the abutment block 17 adheres tightly to the upper surface of the locking block 26 along the first direction X, and the clamping block 18 supports the lower surface of the locking block 26 along the first direction X. This clamping engagement provides double constraint on the actuating member 2 in the first direction X: the abutment block 17 restricts its upward movement from above, and the clamping block 18 supports and restricts its downward movement from below. Through precise assembly tolerances and component dimensional design, it is ensured that after assembly, the abutment block 17 and the clamping block 18 can make tight contact with the upper and lower surfaces of the locking block 26, thereby providing stable vertical positioning. Furthermore, one end of the locking block 26 facing the first structural surface 13 / second structural surface 14 is fitted with the first structural surface 13 / second structural surface 14. This lateral fitting engagement restricts the actuating member 2 in the second direction Y, preventing lateral displacement. Through precise machining and assembly, the side of the snap-fit ​​block 26 is ensured to be in close contact with the structural surface of the guide member 1, thereby ensuring that the actuator 2 moves linearly along the preset sliding trajectory and avoiding lateral swaying. The side of the snap-fit ​​block 26 can be designed with a slight taper or curvature to facilitate assembly and provide a more stable fit.

[0123] Furthermore, one locking block 26 is disposed on the side of the first side plate 21 facing the first structural surface 13, for cooperating with the second limiting structure disposed on the first structural surface 13 for limiting; another locking block 26 is disposed on the side of the second side plate 22 facing the second structural surface 14, for cooperating with the second limiting structure disposed on the second structural surface 14 for limiting. This symmetrical arrangement ensures that the limiting action is evenly distributed on both sides of the moving member 2, effectively preventing the moving member 2 from deviating or jamming due to uneven force during sliding.

[0124] Furthermore, the two sets of second limiting structures symmetrically arranged along the second direction Y, while achieving limiting, also provide strong encapsulation of the second restricted structure, increasing the assembly difficulty of the actuator 2. Based on this, the clamping block 18 in this application is detachably connected to the first structural surface 13 / second structural surface 14, allowing the operator to assemble the actuator 2 first using the contact surface as a reference. Once the locking block 26 is positioned between the contact block 17 and the clamping block 18, the clamping block 18 is then assembled, reducing the assembly difficulty of the actuator 2 and preventing structural damage caused by forced assembly. In addition, the detachable connection design also provides convenience for the installation, maintenance, repair, or replacement of the actuator 2. Specifically, the clamping block 18 can be fixed to the first structural surface 13 / second structural surface 14 with screws; the screw holes can be through holes or blind holes for easy installation and disassembly; or quick-connect methods such as snap-fit ​​or sliding grooves can be used to further simplify the operation.

[0125] According to the description of the above embodiments, the second limiting structure in this application includes abutment blocks 17 and pressing blocks 18 spaced apart along the first direction X, and works in conjunction with the second limiting structure (i.e., locking block 26) on the actuating member 2. When the plate-like structure is nested in the groove 24, the abutment blocks 17 abut against the upper surface of the locking block 26 from above, and the pressing blocks 18 support the lower surface of the locking block 26 from below, thereby forming a stable upper and lower clamping limit on the actuating member 2 in the first direction X. At the same time, the end of the locking block 26 facing the structural surface abuts against the structural surface, further limiting the lateral displacement of the actuating member 2 in the second direction Y. This multi-dimensional precise limiting mechanism effectively solves the problem of the actuating member 2 shifting or loosening during the sliding process, ensuring that the actuating member 2 always stays on the predetermined sliding trajectory during the sliding process, greatly improving the accuracy and stability of the transmission between the reset rod 200 and the lever 100, thereby ensuring the reliability and long service life of the linkage action of the circuit breaker opening and closing system and the energy storage system.

[0126] Thirdly, in some other specific implementations, such as Figure 4 and Figure 9 As shown, the limiting member includes a third limiting structure. The third limiting structure is a boss structure 19 disposed on the first structural surface 13 and / or the second structural surface 14. The boss structure 19 protrudes from the first structural surface 13 and / or the second structural surface 14 along the second direction Y. The distance by which the boss structure 19 protrudes from the first structural surface 13 is greater than the gap between the first structural surface 13 and the first side plate 21. And / or, the distance by which the boss structure 19 protrudes from the second structural surface 14 is greater than the gap between the second structural surface 14 and the second side plate 22.

[0127] The limiting member includes a third limiting structure. The third limiting structure is the bottom surface 28 of the first side plate 21 and / or the second side plate 22. The bottom surface 28 of the first side plate 21 and / or the second side plate 22 is the side of the first side plate 21 and / or the second side plate 22 that is away from the connecting plate 23 in the first direction X. When the plate-like structure is nested within the groove 24, the third limiting member abuts against the third limiting member in the first direction X, thereby limiting the movement of the actuating member 2 in the first direction X and maintaining the gap between the top end 11 and the connecting plate 23.

[0128] The third limiting structure is another specific implementation of the limiting component, used to limit the movement of the actuator 2 in at least the first direction X, to prevent undesirable displacement of the actuator 2 during sliding. Specifically, the third limiting structure can be one or more protrusions integrally formed with the guide 1, directly formed on the structural surface of the guide 1 by molding or machining. Alternatively, it can be an additional component manufactured independently and fixed to the structural surface of the guide 1 by welding, riveting, or bolting, such as a small metal or plastic block.

[0129] The boss structure 19 is a specific form of the third limiting structure, protruding from the first structural surface 13 and / or the second structural surface 14 along the second direction Y. This protrusion design allows it to make physical contact with the corresponding part of the actuator 2, thereby achieving the limiting function. The boss structure 19 can be designed as a continuous strip-shaped protrusion extending along the third direction Z (sliding direction) to continuously provide a limiting effect during the sliding of the actuator 2. Alternatively, the boss structure 19 can also be designed as an intermittent block-shaped protrusion, providing limiting at specific locations on the sliding trajectory, such as near the start or end position of the actuator 2.

[0130] Furthermore, the boss structure 19 protrudes beyond the first structural surface 13 by a distance greater than the gap between the first structural surface 13 and the first side plate 21, and / or, the boss structure 19 protrudes beyond the second structural surface 14 by a distance greater than the gap between the second structural surface 14 and the second side plate 22. This design ensures that the boss structure 19 can effectively pass through the reserved gap between the first structural surface 13 and the first side plate 21 (or between the second structural surface 14 and the second side plate 22), thereby reliably abutting against the third restrictive structure of the actuator 2. If the protrusion distance is insufficient, the boss structure 19 will not be able to contact the restrictive member, thus failing to achieve the limiting function.

[0131] The third confining structure is another specific implementation of the confining component, used to work in conjunction with the third limiting structure (boss structure 19) to precisely limit the movement of the actuator 2 in the first direction X. Specifically, the third confining structure can be the bottom surface 28 of the first side plate 21 and / or the second side plate 22 of the actuator 2, that is, the surface away from the connecting plate 23 in the first direction X. This surface is usually flat to facilitate contact with the boss structure 19. Alternatively, a reinforcing rib or flange can be additionally provided on the bottom surface 28 of the first side plate 21 and / or the second side plate 22 as a third confining structure to increase the contact area or improve wear resistance.

[0132] Furthermore, in order to improve the reliability and wear resistance of the contact between the third limiting structure and the third restricted structure, surface treatment can be performed on the bottom surface 28, such as hardening treatment or coating with wear-resistant material.

[0133] Specifically, when the plate-like structure is nested in the groove 24, the third limiting member abuts against the third limiting member in the first direction X, which is used to restrict the movement of the action member 2 in the first direction X and maintain the gap between the top end 11 and the connecting plate 23, so that the degree of freedom of the action member 2 in the first direction X is effectively restricted, thereby preventing it from displacing perpendicular to the sliding direction during the sliding process, and thus maintaining the preset gap between the top end 11 and the connecting plate 23.

[0134] According to the description of the above embodiments, the limiting member may further include a third limiting structure, which is a boss structure 19 disposed on the first structural surface 13 and / or the second structural surface 14. This boss protrudes from the first structural surface 13 and / or the second structural surface 14 along the second direction Y, and the protrusion distance is greater than the gap between the first structural surface 13 and the first side plate 21 and / or between the second structural surface 14 and the second side plate 22. Simultaneously, the limiting member includes a third limiting structure, which is the bottom surface 28 of the first side plate 21 and / or the second side plate 22, i.e., the side of the first side plate 21 and / or the second side plate 22 that is away from the connecting plate 23 in the first direction X. When the plate-like structure is nested in the groove 24, the boss structure 19 of the third limiting member can abut against the bottom surface 28 of the third limiting member in the first direction X, effectively restricting the movement of the actuating member 2 in the first direction X. This prevents the gap between the top end 11 and the connecting plate 23 from changing due to vertical displacement of the actuating member 2 during sliding, and avoids problems such as shaking, jamming, or increased friction of the actuating member 2 that may be caused by excessive or insufficient gap. This significantly improves the smoothness and reliability of the sliding of the actuating member 2 along the sliding trajectory, thereby ensuring the accuracy of the reset action and the stability of the circuit breaker in long-term use.

[0135] Furthermore, as described in the foregoing embodiments, after the lever 100 abuts against the actuator 2, it can drive the actuator 2 to slide from the first end La to the second end Lb. That is, when the actuator 2 is located on the sliding trajectory between the first end La and the second end Lb, the actuator 2 is necessarily located on the movement trajectory of the lever 100. Based on this, in order to ensure that the actuator 2 is located on the movement trajectory of the lever 100, a corresponding limiting device needs to be set in the third direction Z to prevent the actuator 2 from sliding excessively and causing the reset device 1000 to be unable to perform the reset action. Next, this application will specifically describe the structure and limiting method of this limiting device.

[0136] In some embodiments, such as Figure 5 As shown, the actuator 2 includes an end plate 27 disposed along the third direction Z. When the plate-like structure is nested in the groove 24, the end plate 27 is used to abut against the end face 15, so that the position of the actuator 2 in the third direction Z is maintained between the first end La and the second end Lb.

[0137] The end plate 27 is a structural component of the actuator 2, and it is positioned along a third direction Z, which is the sliding direction of the actuator 2. The end plate 27 can be understood as one or more end structures of the actuator 2 in the sliding direction, and its main function is to provide a physical contact surface so that the actuator 2 can abut against the end face 15 of the guide member 1 when it slides to a preset position. For example, the end plate 27 can be designed as an extension of the overall structure of the actuator 2, forming a flat contact surface; or, the end plate 27 can be an independent component, fixed to the corresponding position of the actuator 2 by welding, bolting, or other methods.

[0138] Specifically, the plate-like structure serves as the guide member 1, and has two opposing end faces 15 along the third direction Z. When the actuating member 2 (U-shaped structure) is nested within the groove 24 of the plate-like structure and slides along the third direction Z, the end plate 27 on the actuating member 2 will contact the end face 15 of the plate-like structure. This contact can be unidirectional, i.e., it only occurs when the actuating member 2 slides to a certain extreme position; or it can be bidirectional, i.e., it occurs when the actuating member 2 slides to either the first end La or the second end Lb. For example, the end plate 27 can be designed to form a surface contact with the end face 15 of the guide member 1 to distribute stress; or, the end plate 27 can be designed to form a line contact or point contact with the end face 15 to provide more precise positioning.

[0139] According to the description of the above embodiments, this application provides an end plate 27 along the third direction Z on the actuator 2, and when the plate-like structure is nested in the groove 24, it abuts against the end face 15 of the guide member 1. This precisely maintains the position of the actuator 2 between the first end La and the second end Lb, preventing the actuator 2 from shifting position or exceeding the predetermined range during sliding. This avoids the actuator 2 from slipping out of the movement trajectory of the lever 100 due to excessive sliding or position shift, thus preventing transmission jamming or functional failure of the reset device 1000. In addition, the actuator 2 being located between the first end La and the second end Lb ensures that it is always within the effective transmission range, providing a stable basis for subsequent reset actions. In view of this, the transmission stability of the transmission module 300 is significantly improved, and the accuracy of the reset action is also guaranteed, thereby enhancing the reliability of the linkage between the circuit breaker energy storage system and the opening and closing system, and effectively solving the transmission instability problem caused by the loss of control of the position of the actuator 2 in the prior art.

[0140] Furthermore, when the reset device 1000 contains an elastic element 3, the elastic element 3 will provide the actuating element 2 with a restoring force opposite to the sliding trajectory, thereby achieving the purpose of limiting the actuating element 2 from excessive sliding toward the second end Lb.

[0141] Based on this, preferably, the actuator 2 includes only one end plate 27 located near the lever 100, which is used to contact the end face 15 of the plate structure near the lever 100, to prevent the actuator 2 from sliding excessively toward the lever 100, thereby reducing the number of parts in the reset device 1000 and lowering the production cost of the circuit breaker.

[0142] Furthermore, this application provides the following two implementation methods for the specific structure of the elastic element 3 for reference.

[0143] Firstly, in some specific implementation methods, such as Figure 2 As shown, the elastic element 3 is a tension spring 31. The torque input end 3a of the tension spring 31 is connected to the guide 1 on the side near the lever 100. The torque output end 3b of the tension spring 31 is connected to the actuating element 2 on the side near the reset rod 200.

[0144] Among them, the tension spring 31 is a common elastic element, characterized by its compact structure, fast response speed, relatively high energy storage density, and provision of stable restoring force in the tensile direction. Specifically, the tension spring 31 stores elastic potential energy through tensile deformation and releases energy when the tension is released. Exemplarily, the tension spring 31 typically includes a helical coil and hooks or loops at both ends for connecting other components.

[0145] The torque input end 3a of the tension spring 31 refers to the connection point where the tension spring 31, after being stretched, drives the moving member 2. This connection can be achieved in various ways, for example, as... Figure 3 As shown, the guide member 1 may be provided with a first hook 5, a pin, or a hole, and the hook or ring of the tension spring 31 may be directly hooked or fixed through the pin. Alternatively, the end of the tension spring 31 may be bolted or welded to the guide member 1 through a connector.

[0146] Specifically, the torque input end 3a is connected to the side of the guide 1 near the lever 100 to ensure that the stretching direction of the tension spring 31 matches the sliding direction of the actuating member 2, and to enable it to effectively store energy when the actuating member 2 is pushed by the lever 100.

[0147] The torque output end 3b of the tension spring 31 refers to the connection point where the restoring force of the tension spring 31 acts on the actuating member 2 when it is stretched. This connection can also be achieved in various ways, for example, as... Figure 5 As shown, the actuator 2 may be provided with a second hook 6, a pin, or a hole, and the other end of the tension spring 31 may be directly hooked or fixed through the pin. Alternatively, the end of the tension spring 31 may be bolted or welded to the actuator 2 using a connector.

[0148] Specifically, the torque input end 3a of the tension spring 31 is connected to the side of the actuator 2 near the reset rod 200 so that the tension spring 31 can be effectively stretched during the sliding process of the actuator 2, and when the energy is released in the future, the force can be directly applied to the actuator 2, thereby pushing the actuator 2 to reset.

[0149] Furthermore, based on the specific embodiments of the guide member 1 and the actuating member 2 in this application, the torque input end 3a of the tension spring 31 can be connected to the end face 15 of the plate structure near the lever 100, or to the side of the first structural surface 13 / second structural surface 14 near the lever 100. Correspondingly, the torque output end 3b of the tension spring 31 can be connected to the end plate 27 near the reset rod 200, or to the side of the first side plate 21 / second side plate 22 near the reset rod 200.

[0150] For example, the bottom surface 28 of the first structural surface 13 and the first side plate 21 are respectively provided with structures for engaging the hook of the tension spring 31, so that the torque input end 3a of the tension spring 31 is connected to the side of the first structural surface 13 near the lever 100, and the torque output end 3b of the tension spring 31 is connected to the side of the first side plate 21 near the reset rod 200.

[0151] Secondly, in some other specific implementations, such as Figure 11 As shown, the elastic element 3 is a compression spring 32. The torque input end 3a of the compression spring 32 is connected to the side of the guide member 1 near the lever 100 or the reset rod 200. The torque output end 3b of the compression spring 32 is connected to the side of the actuating member 2 near the lever 100 or the reset rod 200.

[0152] Among them, the compression spring 32 is another common elastic element, characterized by providing a stable restoring force in the compression direction, a relatively robust structure, and a large elastic force within a specific space. Specifically, the compression spring 32 stores elastic potential energy through compression deformation and releases energy when the compression is released. Exemplarily, it typically includes a helical coil with flat or ground end faces 15 at both ends for bearing pressure.

[0153] The torque input end 3a of the compression spring 32 refers to the connection point where the compression spring 32, after being compressed, drives the actuating element 2 to move. This connection can be achieved in various ways, for example, as... Figure 8 , Figure 9 as well as Figure 13 As shown, the guide member 1 may be provided with a support surface, a limiting groove, or a first fixing seat 7. One end of the compression spring 32 may be placed directly on the support surface or limited by the first fixing seat 7. Alternatively, the end of the compression spring 32 may be bolted or welded to the guide member 1 by a connector.

[0154] Specifically, the torque input end 3a of the compression spring 32 is connected to the side of the guide member 1 near the lever 100 or the reset rod 200, which is used to select the best fixing point according to the specific spatial layout and mechanical transmission requirements, so as to ensure that the compression spring 32 can be effectively compressed and stored when the actuating member 2 slides.

[0155] The torque output end 3b of the compression spring 32 refers to the connection point where the restoring force of the compression spring 32 acts on the actuating member 2 when it is compressed. This connection can also be achieved in various ways, for example, as... Figure 11 As shown, the actuator 2 may be provided with a support surface, a limiting groove, or a second fixing seat 8. The other end of the compression spring 32 may be placed directly on the support surface or limited by the second fixing seat 8. Alternatively, the end of the compression spring 32 may be bolted or welded to the actuator 2 by a connector.

[0156] Specifically, the torque output end 3b of the compression spring 32 is connected to the side of the actuating element 2 near the lever 100 or the reset rod 200. This is so that the compression spring 32 can be effectively compressed during the sliding process of the actuating element 2, and when the energy is released subsequently, the force can be directly applied to the actuating element 2, thereby pushing the actuating element 2 to reset. The flexibility of this connection method allows for optimized configuration according to the actual mechanical layout and force transmission path.

[0157] Furthermore, based on the specific embodiments of the guide member 1 and the actuating member 2 in this application, the torque input end 3a of the tension spring 31 can be connected to the end face 15 of the plate structure near the lever 100, or to the side of the first structural surface 13 / second structural surface 14 near the lever 100. Correspondingly, the torque output end 3b of the tension spring 31 can be connected to the end plate 27 near the lever 100, or to the side of the first side plate 21 / second side plate 22 near the reset rod 200.

[0158] For example, a fixing seat for limiting the compression spring 32 is provided on the end face 15 of the plate structure near the lever 100 and on the end plate 27 near the lever 100, so that the torque input end 3a of the compression spring 32 is connected to the end face 15 of the plate structure near the lever 100, and the torque output end 3b of the tension spring 31 is connected to the end plate 27 near the lever 100.

[0159] Based on the description of the above embodiments, this application optimizes the storage and release process of potential energy in the reset device 1000 by specifically defining the type and connection position of the elastic element 3, thereby solving the problems of low reset efficiency and reliability caused by improper selection of the elastic element 3. Specifically, when the elastic element 3 is a tension spring 31, the torque output end 3b of the tension spring 31 is connected to the side of the guide 1 near the lever 100, and the torque input end 3a is connected to the side of the actuating element 2 near the reset rod 200. This connection method ensures that during the sliding process of the actuating element 2, the tension spring 31 is stretched to store potential energy and efficiently transmits torque to the actuating element 2 when released, avoiding energy loss. Alternatively, when the elastic element 3 is a compression spring 32, the torque output end 3b and the input end of the compression spring 32 can be flexibly connected to the side of the guide 1 near the lever 100 or the reset rod 200 and the side of the actuating element 2 near the lever 100 or the reset rod 200. This design adapts to different spatial layouts, allowing the compression spring 32 to store energy during compression and release it stably during the reset action, improving the overall transmission accuracy. These features collectively enhance the stability and reliability of the reset action, enabling the reset device 1000 to maintain efficient and stable performance during long-term operation. Secondly, this application provides a circuit breaker including a closing / opening system, an energy storage system, and the reset device described in any of the above embodiments. The reset device links the closing / opening system and the energy storage system, enabling the energy storage system to perform energy storage actions according to the actions of the closing / opening system.
