Description

Technical Field

[0001] This invention relates to the field of low-voltage electrical appliances, and more specifically to an operating mechanism and a disconnecting switch. Background Technology

[0002] A switching device is a device used to close and open a circuit. It typically includes an operating mechanism and at least one conductive device. The operating mechanism drives the contact mechanism of each conductive system to achieve the opening and closing of the circuit. The opening and closing of the contact mechanism is accomplished by the separation or contact of the moving contact and the stationary contact. The final gap size when the moving contact and the stationary contact are disconnected determines the electrical performance of the switching device. In existing switching devices, due to their external dimensions and internal structure, a larger disconnection gap cannot be achieved between the moving contact and the stationary contact, which in turn affects the electrical performance of the product. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an operating mechanism that enables the contact mechanism to have a large opening distance, as well as an isolating switch using the operating mechanism.

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

[0005] An operating mechanism includes a primary energy storage mechanism and an output shaft, and also includes a secondary energy storage mechanism. The secondary energy storage mechanism includes a second drive structure and a second energy storage elastic element coaxially mounted on the output shaft. The second drive structure includes a fixing element and a locking assembly. The fixing element is provided with two limit slots. When the circuit is opened, the primary energy storage mechanism releases energy to drive the output shaft to rotate, storing energy for the second energy storage elastic element. After the locking part of the output shaft drives the locking assembly to slide out from one of the limit slots and unlock, the second energy storage elastic element releases energy to drive the locking assembly to drive the output shaft to continue rotating to the open position, and the locking part is driven to slide into the other limit slot and is limited and locked.

[0006] Preferably, the two limiting slots are the first limiting slot and the second limiting slot. During the opening process, the locking part first rotates within the first limiting slot with the output shaft for a preset empty stroke. After the locking part and the first limiting slot have no rotational margin, the second energy storage elastic element begins to store energy.

[0007] Preferably, the central angle of the first limiting groove is greater than the central angle of the second limiting groove, and the central angle of the second limiting groove is equal to the central angle of the locking part. During the opening process, the locking part first unlocks with the first limiting groove and then locks with the second limiting groove. During the closing process, the locking part first unlocks with the second limiting groove and then locks with the first limiting groove.

[0008] Preferably, the locking assembly includes a clamping member, a sliding member, and a locking member. The clamping member is fixedly connected to the output shaft, the sliding member is rotatably mounted on the output shaft, and slidably mounted with the locking member. The locking member has a locking part, and the locking member can rotate around the output shaft via the sliding member and slide radially relative to the sliding member along the output shaft. A second energy storage elastic member is connected between the clamping member and the locking member, and drives the locking part of the locking member to lock with at least one of the two limiting grooves.

[0009] Preferably, when the locking part engages with a limiting groove, the rotation of the output shaft causes the second energy-storing elastic element to store energy through the clamping member, and the clamping member drives the locking part to slide in a first direction relative to the sliding member, so that the locking part separates and unlocks from one limiting groove. After unlocking, the second energy-storing elastic element releases energy and drives the clamping member to drive the output shaft to continue rotating. When the locking part rotates to the position corresponding to another limiting groove, the locking part is driven to slide in a second direction relative to the sliding member, and is locked with the other limiting groove.

[0010] Preferably, the fixing member has a first clearance hole in the middle for assembling the output shaft, a central groove on one side surface of the fixing member for the locking assembly to rotate, and two limiting grooves spaced apart circumferentially along the central groove.

[0011] Preferably, the sliding member has a circular shaft hole in the middle that is rotatably connected to the output shaft, and one side edge of the locking member protrudes outward to form a locking part. The locking member adjacent to the locking part has a first locking arm on each side. The locking member has a second clearance hole in the middle. The locking member is slidably sleeved on the outer periphery of the sliding member through the second clearance hole. The direction of the locking part closer to the sliding member is the first direction, and the direction of the locking part away from the sliding member is the second direction.

[0012] The clamping member has a connecting shaft hole in the middle for connecting to the output shaft. On opposite sides of the clamping member are second locking arms that correspond to the first locking arm respectively. On the other side of the clamping member is an outwardly protruding part. The opposite two edges of the protruding part serve as mating parts for abutting against the corresponding first locking arm and pushing the locking member to slide and unlock in the first direction.

[0013] Preferably, the second energy storage elastic element includes a rotating part coaxially mounted with the output shaft. The rotating part is connected to two elastic arms. The first and second locking arms located on the same side abut against the same elastic arm. When the second energy storage elastic element stores energy, the pressing member and the sliding member are misaligned. One elastic arm abuts against one of the first locking arms, and the other elastic arm abuts against one of the second locking arms on the other side.

[0014] When the locking part moves along the first direction and separates from the limiting groove to unlock, the first locking arm presses the elastic arm and undergoes elastic deformation; when the second elastic energy storage element releases energy to drive the locking part to rotate, the elastic arm releases energy to push the first locking arm, so that the locking part is limited and locked with another limiting groove along the second direction.

[0015] Preferably, the primary energy storage mechanism includes a first drive structure and at least one first energy storage elastic element. The first drive structure includes an operating shaft and a rotating element that are sequentially linked. The rotating element is linked with the output shaft. The first energy storage elastic element is coupled with the rotating element. The operating shaft drives the rotating element to rotate so that the first energy storage elastic element rotates to a balance position to store energy. After the first energy storage elastic element passes the balance position, it releases energy and drives the rotating element to rotate, thereby driving the output shaft to rotate.

[0016] Preferably, when the circuit breaker is opened, the first energy storage elastic element releases energy and drives the output shaft to rotate from the closed position to the first critical position through the rotating element. The rotation of the output shaft causes the second energy storage elastic element to release energy after storing it, and drives the output shaft to continue rotating to the open position.

[0017] Preferably, when the circuit is closed, the first energy storage elastic element releases energy and drives the output shaft to rotate to the closed position via the rotating element.

[0018] Preferably, the first drive structure further includes a transmission assembly, an operating shaft, a transmission assembly, and a rotating component. The operating shaft drives the rotating component to rotate via the transmission assembly, and the transmission assembly and the rotating component are respectively linked with the output shaft. When opening the circuit, the operating shaft drives the rotating component to rotate via the transmission assembly. The rotation of the rotating component causes the first energy storage elastic element to release energy after passing the equilibrium position. The release of energy by the first energy storage elastic element drives the output shaft to rotate to the first critical position via the rotating component. The rotation of the output shaft causes the second energy storage elastic element to store energy and then release it, driving the output shaft to continue rotating to the open position. When closing the circuit, the operating shaft drives the rotating component to rotate via the transmission assembly, causing the first energy storage elastic element to rotate to the equilibrium position to store energy and then release it after passing the equilibrium position. At the same time, the transmission assembly also drives the output shaft to rotate, causing the second energy storage elastic element to store energy and then release it. The release of energy by the first energy storage elastic element drives the output shaft to rotate to the closed position via the rotating component.

[0019] Preferably, the transmission assembly includes a transmission shaft and a transmission plate. The transmission shaft is rotatable, and the transmission plate is linearly movable. The operating shaft drives the rotating component to rotate through the transmission shaft. The operating shaft drives the transmission plate to move linearly between the open position and the closed position of the transmission plate. When the circuit is closed, the operating shaft drives the transmission plate to move towards the closed position of the transmission plate, and drives the output shaft to rotate through the transmission plate.

[0020] Preferably, the transmission shaft includes a first transmission shaft and a second transmission shaft. The first transmission shaft and the second transmission shaft are fixedly connected or in transmission cooperation. The first transmission shaft is linked with the operating shaft and the transmission plate, respectively. The second transmission shaft is linked with the rotating component, and the transmission plate and the rotating component are in linkage cooperation with the output shaft, respectively.

[0021] Preferably, the operating shaft is provided with a first gear surrounding the side wall, the side of the first transmission shaft facing the operating shaft is provided with a gear part that meshes with the first gear, the middle part of the first transmission shaft is provided with a second gear surrounding the side wall of the first transmission shaft, the second gear meshes with the teeth of the transmission plate, the transmission plate is provided with a first lever, and the second transmission shaft is provided with a third lever for driving the rotating part to rotate.

[0022] Preferably, the side wall of the output shaft is provided with a protruding first stop and a second lever, the first stop being used to cooperate with the first lever of the transmission plate.

[0023] Preferably, one end of the rotating component is rotatably mounted, and a spring groove is provided on each of the opposite sides of the rotating component. The other end of the rotating component is provided with a second stop, a third stop, and a fourth stop in sequence along the circumferential direction. The second stop and the third stop are used to abut against the third lever, and the third stop and the fourth stop are used to cooperate with the second lever.

[0024] Preferably, the output shaft includes a first output shaft and a second output shaft, one end of the first output shaft and the second output shaft are plugged into each other, and the other end of the first output shaft and the second output shaft are used for transmission connection with the contact mechanism. The first output shaft is driven by a primary energy storage mechanism, and the second output shaft is driven by a secondary energy storage mechanism.

[0025] Preferably, the central axis of the rotating component of the first drive structure is perpendicular to the axis of the output shaft.

[0026] The present invention also provides a disconnecting switch, including a housing, wherein at least one conductive system and any of the above-described operating mechanisms are assembled within the housing, and the contact mechanism of the conductive system is linked to the output shaft of the operating mechanism.

[0027] The present invention provides an operating mechanism and a disconnecting switch. The primary energy storage mechanism of the operating mechanism releases energy to drive the output shaft to rotate and stores energy in the secondary energy storage mechanism. After the secondary energy storage mechanism is unlocked, it releases energy and can drive the output shaft to continue rotating to the open position. The two driving rotations of the output shaft can drive the contact mechanism to have a larger opening distance when the circuit is opened, which is beneficial to ensuring the electrical performance of the product.

[0028] In addition, at the initial stage of opening, the locking part first rotates within the first limit groove with the output shaft for a preset empty stroke. After the locking part and the first limit groove have no rotational margin, the second energy storage elastic element begins to store energy. Due to the existence of rotational margin, it is not necessary to overcome the elastic force of the second energy storage elastic element in the secondary energy storage mechanism at the initial stage of opening, thus improving the breaking performance.

[0029] In addition, the motion state of the opening and closing process is not symmetrical. When closing, in order to ensure the closing speed, the driving force is mainly provided by the energy release of the first energy storage mechanism. In the last stage of the opening process, the first energy storage mechanism has completed the energy release, while the second energy storage mechanism has not completed the energy release. The energy release is completed by the second energy storage mechanism alone. In this way, the closing speed when closing is guaranteed, and the opening distance when opening is guaranteed.

[0050] The following is in conjunction with the appendix Figures 1 to 22 The given embodiments further illustrate specific implementations of an operating mechanism and disconnecting switch of the present invention. The operating mechanism and disconnecting switch of the present invention are not limited to the descriptions in the following embodiments.

[0051] A disconnecting switch includes a housing, within which an operating mechanism and at least one conductive system are assembled. Each conductive system includes a contact mechanism linked to the operating mechanism. The contact mechanism includes a moving contact and a stationary contact that cooperate with each other. The moving contact is linked to the operating mechanism, so that the moving contact contacts or separates from the stationary contact under the drive of the operating mechanism, thereby connecting or disconnecting the conductive system. Existing operating mechanisms include a primary energy storage mechanism 2. During opening and closing, the primary energy storage mechanism 2 rotates to store energy. After passing the dead point, the primary energy storage mechanism 2 releases energy to drive the output shaft 4 to rotate rapidly to the open or closed position.

[0052] The improvement of this application lies in that the operating mechanism includes a primary energy storage mechanism 2, a secondary energy storage mechanism 3, and an output shaft 4. The primary energy storage mechanism 2 and the secondary energy storage mechanism 3 are respectively linked to the output shaft 4. During the opening process, after the primary energy storage mechanism 2 has finished storing energy, it releases energy to drive the output shaft 4 to rotate and store energy for the secondary energy storage mechanism 3. After the output shaft 4 opens and rotates to unlock the secondary energy storage mechanism, the unlocked secondary energy storage mechanism 3 releases energy, and the output shaft 4 continues to rotate until the secondary energy storage mechanism 3 locks again. By setting the secondary energy storage mechanism 3, this application enables the output shaft 4 to be driven to rotate twice by the primary energy storage mechanism 2 and the secondary energy storage mechanism 3 during the opening process, which can drive the contact mechanism to have a larger opening distance when opening, thus ensuring the electrical performance of the product.

[0053] Combination Figure 1-22 A specific embodiment of an operating mechanism is provided, but its specific structure is not limited to this embodiment.

[0054] like Figure 1 As shown, the operating mechanism includes a housing 1, and a primary energy storage mechanism 2, a secondary energy storage mechanism 3, and an output shaft 4 are assembled inside the housing 1.

[0055] like Figure 1-3 As shown, the primary energy storage mechanism 2 includes a first drive structure and at least one first energy storage elastic element 26. In this embodiment, the first drive structure includes an operating shaft 21 and a rotating element 25 connected in sequence. The rotating element 25 is linked with the output shaft 4. A pair of first energy storage elastic elements 26 are respectively connected to opposite sides of the rotating element 25 for cooperation with the rotating element 25. The operating shaft 21 drives the rotating element 25 to rotate so that the first energy storage elastic element 26 rotates to the equilibrium position to store energy. After the first energy storage elastic element 26 passes the equilibrium position, it releases energy, drives the rotating element 25 to rotate rapidly, and drives the output shaft 4 to rotate through the rotating element 25. The first drive structure of the primary energy storage mechanism 2 is arranged along the vertical direction of the housing 1. A pair of first energy storage elastic elements 26 are arranged on the left and right sides of the first drive structure and are respectively connected to the inner sidewall of the housing 1. An operation hole 11 is provided on the upper sidewall of the housing 1. The operation shaft 21 of the primary energy storage mechanism 2 is driven by a handle or other tools. The operation shaft 21 drives the rotating element 25 to rotate through the transmission assembly, so that the primary energy storage mechanism 2 stores and releases energy, thereby driving the output shaft 4 arranged in the direction perpendicular to the front and rear of the housing 1 to rotate. Linkage holes 12 are provided on the front and rear sidewalls of the housing 1. The contact mechanism of the conductive system is linked to the end of the output shaft 4 through the linkage hole 12. When the output shaft 4 rotates to the closed position or the open position, it drives the contact mechanism to close or open. This is the prior art in this field.

[0056] Preferably, the operating mechanism further includes a secondary energy storage mechanism 3. In this embodiment, the secondary energy storage mechanism 3 includes a second driving structure and a second energy storage elastic element 35. Figure 1The central axes of the first drive structure and the second drive structure are perpendicular. (Reference) Figure 12-15 As shown, the second drive structure includes a fixing member 31 and a locking assembly. The second drive structure and the second energy storage elastic member 35 are coaxially assembled on the output shaft 4. The fixing member 31 is fixedly assembled and has two limiting grooves, namely the first limiting groove 313 and the second limiting groove 314. The fixing member 31 can be the housing 1 or a component that is fixedly assembled on the output shaft 4. Preferably, the fixing member 31 is a component that is assembled on the output shaft 4. The locking assembly includes a locking part 321 that is limited and cooperates with the limiting groove. The second energy storage elastic member 35 acts on the locking assembly to lock the locking part 321 with the limiting groove of the fixing member 31. The primary energy storage mechanism 2 drives the output shaft 4 to rotate, which can store energy for the second energy storage elastic member 35. After the output shaft 4 drives the locking part 321 of the locking assembly to slide out from one of the limiting grooves and unlock, the second energy storage elastic member 35 releases energy to drive the locking assembly to drive the output shaft 4 to continue rotating until the locking part 321 is driven to slide into the other limiting groove and is limited and locked.

[0057] In this embodiment, when the circuit breaker is opened, the primary energy storage mechanism 2 rotates to store energy, and then the primary energy storage mechanism 2 releases energy to drive the output shaft 4 to rotate in the opening direction, storing energy for the second energy storage elastic member 35. After the output shaft 4 drives the locking part 321 of the locking assembly to slide out from one of the limiting grooves along the first direction to unlock, the second energy storage elastic member 35 releases energy to drive the locking assembly to drive the output shaft 4 to continue rotating to the opening position, until the locking part 321 is driven to slide into another limiting groove along the second direction and is limited and locked. Specifically, the primary energy storage mechanism 2 rotates to store energy, and then releases energy to drive the output shaft 4 to rotate from the closed position to the open position. The rotation of the output shaft 4 drives the locking component of the second drive structure and the second energy storage elastic element 35 to store energy. When the primary energy storage mechanism 2 releases energy to drive the output shaft 4 to rotate to the first critical position, the output shaft 4 drives the locking part 321 of the locking component to slide out from one of the limiting slots along the first direction to unlock. The second energy storage elastic element 35 releases energy to drive the locking component to drive the output shaft 4 to continue rotating. At this time, the driving force for the output shaft 4 to continue rotating mainly comes from the secondary energy storage mechanism 3, until the output shaft 4 rotates to the open position. The locking part 321 is driven to slide into another limiting slot along the second direction and is limited and locked. The secondary energy storage mechanism 3 locks again. In this embodiment, by setting a secondary energy storage mechanism 3, the output shaft is driven to rotate to the first critical position by the primary energy storage mechanism 2 when the circuit is opened. The secondary energy storage mechanism 3 first stores energy and then releases energy to drive the output shaft to continue rotating from the first critical position to the open position. Through two driving rotations, the contact mechanism can be driven to have a larger opening distance when opened, which helps to ensure the electrical performance of the product. The first critical position is the position where the locking part 321 of the secondary energy storage mechanism 3 slides out of a limiting groove to unlock and begin releasing energy. It is an intermediate position for the output shaft 4 to rotate from the closed position to the open position. When the output shaft 4 is in the closed position, the locking part 321 is locked with one limiting groove. When the output shaft 4 rotates to the first critical position, the locking part 321 slides out of a limiting groove to unlock and begin releasing energy. When the output shaft 4 rotates to the open position, the locking part 321 is locked with another limiting groove. In this embodiment, the output shaft 4 is driven by the first energy storage elastic member 26 to release energy from the closed position to the first critical position, and is mainly driven by the second energy storage elastic member 35 to release energy from the first critical position to the open position. Of course, when the second energy storage elastic member 35 just releases energy, the first energy storage elastic member 26 can provide driving force for the continued rotation of the output shaft 4, which is also possible and falls within the protection scope of this application.

[0058] In one embodiment, when the operating mechanism is closed, a similar technical solution to the opening process is adopted. The primary energy storage mechanism 2 rotates to store energy, and then releases energy to drive the output shaft 4 to rotate from the opening position to the closing position. The rotation of the output shaft 4 drives the locking component of the second drive structure, which in turn stores energy in the second energy storage elastic element 35. When the output shaft 4 rotates to the second critical position, the locking part 321 of the locking component is driven to slide out of the aforementioned other limiting groove along the first direction to unlock. The second energy storage elastic element 35 releases energy to drive the locking component to continue rotating the output shaft 4 until it rotates to the opening position. At this point, the locking part 321 is driven to slide into a limiting groove along the second direction and is locked. The secondary energy storage mechanism 3 then locks again. However, in this solution, the driving force from the output shaft 4 from the second critical position to the closing position is mainly provided by the secondary energy storage mechanism 3, which makes it difficult to guarantee the closing speed during closing. The second critical position, which is the position where the locking part 321 of the secondary energy storage mechanism 3 slides out of the other limiting groove to unlock and begin releasing energy, is an intermediate position where the output shaft 4 rotates from the open position to the closed position. It should be noted that the first critical position and the second critical position may be the same position or they may not be the same position.

[0059] In particular, such as Figure 1-3 As shown in a preferred embodiment of this application, the primary energy storage mechanism 2 includes a first driving structure and at least one first energy storage elastic element 26. The first driving structure further includes a transmission assembly, namely, the first driving structure includes an operating shaft 21, a transmission assembly, and a rotating element 25 connected in sequence. The transmission assembly and the rotating element 25 are respectively connected to the output shaft 4. The first energy storage elastic element 26 cooperates with the rotating element 25. The rotation of the rotating element 25 causes the first energy storage elastic element 26 to rotate to a balance position to store energy, and after passing the balance position, it releases energy to drive the rotating element 25 to rotate. The operating shaft 21 drives the rotating element 25 through the transmission assembly, so that the first energy storage elastic element 26 stores and releases energy to drive the output shaft 4 to rotate. It can also directly drive the output shaft 4 to rotate through the transmission assembly. During the opening process, the operating shaft 21 drives the rotating component 25 to rotate via the transmission assembly. During the opening process, the transmission assembly does not drive the output shaft 4. The rotation of the rotating component 25 causes the first energy storage elastic component 26 to release energy after passing the equilibrium position, that is, after passing the dead point. The release of energy by the first energy storage elastic component 26 drives the rotating component 25 to rotate rapidly. The rotating component 25 drives the output shaft 4 to rotate. The rotation of the output shaft 4 drives the locking assembly of the second drive structure and stores energy for the second energy storage elastic component 35. When the output shaft 4 rotates to the first critical position, the rotation of the output shaft 4 drives the locking part 321 of the locking assembly to slide out of the first limit groove 313 to unlock. The release of energy by the second energy storage elastic component 35 drives the locking assembly to drive the output shaft 4 to continue rotating to the opening position, and the locking part 321 is driven to slide into the second limit groove 314 to lock again. The opening process is similar to the above.

[0060] The difference lies in the closing process. During closing, the operating shaft 21 drives the rotating member 25 to rotate via the transmission assembly. Simultaneously, the transmission assembly also drives the output shaft 4 to rotate. That is, the rotation of the rotating member 25 causes the first energy storage elastic member 26 to rotate, while the rotation of the output shaft 4 drives the locking assembly to cause the second energy storage elastic member 35 to first store energy and then release it. When the output shaft 4 rotates to the second critical position, the rotation of the output shaft 4 drives the locking part 321 of the locking assembly to slide out of the second limit groove 314 to unlock and release energy. The release of energy from the second energy storage elastic member 35 drives the locking assembly to drive the output shaft 4 to continue rotating towards the closing position until the locking part 321 is driven to slide into the first limit groove 313 to lock again. At the same time, the rotation of the rotating member 25 causes the first energy storage elastic member 26 to release energy after passing the equilibrium position, that is, after passing the dead point. The release of energy from the first energy storage elastic member 26 drives the rotating member 25 to rotate rapidly. The release of energy from the first energy storage elastic member 26 drives the output shaft 4 to rotate to the closing position through the rotating member 25. During the closing process, after the second energy storage elastic element 35 releases energy past the dead point, it continuously drives the output shaft 4 to rotate to the closing position. The first energy storage elastic element 26 provides the main driving force for the output shaft 4 to rotate to the closing position to ensure the closing speed.

[0061] Preferably, in the final stage of closing, the first energy storage elastic element 26 and the second energy storage elastic element 35 can jointly drive the output shaft 4 to rotate to the closed position. That is, after the output shaft 4 rotates past the second critical position to unlock the second drive structure and the rotating element 25 rotates to cause the first energy storage elastic element 26 to pass the equilibrium position, the first energy storage elastic element 26 and the second energy storage elastic element 35 jointly drive the output shaft 4 to rotate to the closed position. Of course, only the first energy storage elastic element 26 can drive the output shaft 4 to rotate to the closed position. During the entire closing process, the energy release of the primary energy storage mechanism 2 provides the main driving force for the rotation of the output shaft 4. The energy release of the secondary energy storage mechanism 3 can also provide part of the driving force for the rotation of the output shaft 4. The energy release of the secondary energy storage mechanism 3 can also not provide driving force for the rotation of the output shaft 4. Whether the secondary energy storage mechanism 3 releases energy or not can be adjusted according to actual needs. Furthermore, during the closing process, whether the transmission assembly first drives the output shaft 4 to rotate to the second critical position, or whether the transmission assembly first drives the rotating part 25 to rotate to make the first energy storage elastic element 26 cross the equilibrium position, can be adjusted accordingly as needed. As long as the first energy storage elastic element 26 provides the main driving force, and after the first energy storage elastic element 26 releases energy after crossing the equilibrium position, it can continue to drive the output shaft 4 to rotate to the closing position, all of which fall within the protection scope of this application. The second critical position, which is the position where the locking part 321 of the secondary energy storage mechanism 3 slides out of the other limiting groove to unlock and begin releasing energy, is an intermediate position for the output shaft 4 to rotate from the open position to the closed position. When the output shaft 4 is in the open position, the locking part 321 is locked with the other limiting groove. When the output shaft 4 rotates to the second critical position, the locking part 321 slides out of the other limiting groove to unlock and begin releasing energy. When the output shaft 4 rotates to the closed position, the locking part 321 is locked with a limiting groove. In this embodiment, the output shaft 4 is driven from the open position to the second critical position by the transmission component, and / or driven by the transmission component first and then by the first energy storage elastic element 26 releasing energy. After the first energy storage elastic element 26 releases energy, the output shaft 4 is driven to rotate until the closed position.

[0062] In other words, the motion state of the operating mechanism in this embodiment during the opening and closing process is not symmetrical. During closing, in order to ensure the closing speed, the driving force is mainly provided by the energy release of the first energy storage mechanism. In the last stage of the opening process, the first energy storage mechanism has completed the energy release, while the second energy storage mechanism has not completed the energy release. The energy release is completed by the second energy storage mechanism alone. In this way, the closing speed during closing is guaranteed, and the opening distance during opening is also guaranteed. This is an embodiment of the present invention.

[0063] Preferably, the two limiting grooves are a first limiting groove 313 and a second limiting groove 314. The central angle of the first limiting groove 313 is larger than that of the second limiting groove 314, and the central angle of the second limiting groove 314 is equal to that of the locking part 321. This ensures that the locking part 321 has a certain rotational margin when engaging with the first limiting groove 313, and no rotational margin when engaging with the second limiting groove 314. During the opening process, the locking part 321 first rotates a preset empty stroke within the first limiting groove 313 with the output shaft 4. After the locking part 321 has no rotational margin with the first limiting groove 313, the second energy storage elastic element 35 begins to store energy when the locking part 321 engages with the first limiting groove 313. Thus, in the initial stage of opening, due to the existence of the preset empty stroke, i.e., the existence of the rotational margin, it is not necessary to overcome the elastic force of the second energy storage elastic element 35 in the secondary energy storage mechanism 3, thereby improving the breaking performance.

[0064] The specific opening process is as follows: During the period when the output shaft 4 rotates to the first critical position due to the release of energy by the primary energy storage mechanism 2, the locking part 321 first rotates within the first limiting groove 313 with the output shaft 4 for a preset empty stroke. During this stage, the second energy storage elastic member 35 does not store energy. After the locking part 321 and the first limiting groove 313 have no rotational margin, that is, under the locking part 321 and the first limiting groove 313 in a locking engagement, the second energy storage elastic member 35 begins to store energy. When the output shaft 4 rotates to the first critical position, the locking part 321 is driven to slide along the first direction, causing the locking part 321 to separate and unlock from the first limiting groove 313, and the second energy storage... After the elastic element 35 has finished storing energy, the second energy-storing elastic element 35 releases energy to drive the locking part 321 to rotate, simultaneously driving the output shaft 4 to continue rotating until the locking part 321 is driven to slide into the second limiting groove 314 along the second direction and is locked, completing the opening process. During the closing process, as the output shaft 4 rotates from the open position to the second critical position, since there is no rotational margin when the locking part 321 engages with the second limiting groove 314, the second energy-storing elastic element 35 synchronously stores energy until the locking part 321 separates from the second limiting groove 314 and unlocks. The second energy-storing elastic element 35 then begins to release energy to drive the output shaft 4 to continue rotating. Thus, during the process where the output shaft 4 rotates to the point where there is no rotational margin between the locking part 321 and the first limiting groove 313, the existence of rotational margin eliminates the need to overcome the elastic force of the second energy-storing elastic element 35 in the secondary energy storage mechanism 3, improving the breaking performance.

[0065] The following description, in conjunction with the drawings, further illustrates the specific structure of the preferred embodiment of the operating mechanism. The operating mechanism is not limited to this embodiment.

[0066] like Figure 2-3As shown, the primary energy storage mechanism 2 includes a first drive structure and a pair of first energy storage elastic elements 26. The first drive structure includes an operating shaft 21, a transmission assembly, and a rotating element 25 connected in sequence. The transmission assembly and the rotating element 25 are respectively connected to the output shaft 4. In this embodiment, the transmission assembly includes a transmission shaft and a transmission plate 23. The transmission shaft is rotatably configured, and the transmission plate 23 is linearly movable. The operating shaft 21 drives the rotating element 25 to rotate through the transmission shaft. The operating shaft 21 drives the transmission plate 23 to move linearly between the open position and the closed position of the transmission plate. When the circuit is open, the operating shaft 21 drives the transmission plate 23 to move towards the open position, and the transmission plate 23 does not drive the output shaft 4 to rotate. When the circuit is closed, the operating shaft 21 drives the transmission plate 23 to move towards the closed position, and the transmission plate 23 drives the output shaft 4 to rotate. The operating shaft 21 can directly drive the transmission plate 23 to move, or it can indirectly drive the transmission plate 23. In this embodiment, the transmission plate 23 is driven by the rotation of the transmission shaft, that is, the transmission shaft drives the rotating element 25 to rotate and also drives the transmission plate 23 to move.

[0067] The transmission shaft includes a split first transmission shaft 22 and a second transmission shaft 24. One end of the first transmission shaft 22 and the second transmission shaft 24 are fixedly connected or in transmission cooperation. The first transmission shaft 22 is linked to the operating shaft 21 and the transmission plate 23 respectively. The second transmission shaft 24 is linked to the rotating component 25. The transmission plate 23 and the rotating component 25 are linked to the output shaft 4 respectively.

[0068] When the circuit breaker is opened, the operating shaft 21 drives the first transmission shaft 22 to rotate. The first transmission shaft 22 drives the transmission plate 23 to move horizontally to the open position of the transmission plate, and drives the rotating component 25 to rotate through the second transmission shaft 24, causing the first energy storage elastic component 26 to store energy. After the first energy storage elastic component 26 passes the equilibrium position, it releases energy, and drives the output shaft 4 to rotate from the closed position to the first critical position through the rotating component 25. The second energy storage elastic component 35 first completes energy storage and then releases energy, driving the output shaft 4 to rotate to the open position. Preferably, when the output shaft 4 rotates to the open position, the output shaft 4 and the transmission plate 23 are limited.

[0069] When the circuit is closed, the operating shaft 21 drives the first transmission shaft 22 to rotate. The first transmission shaft 22 drives the transmission plate 23 to move horizontally to the closed position. The transmission plate 23 drives the output shaft 4 to rotate from the open position to the second critical position. The rotation of the first transmission shaft 22 drives the rotating component 25 to rotate through the second transmission shaft 24. The rotation of the output shaft 4 can cause the second energy storage elastic component 35 to store energy. The rotation of the rotating component 25 causes the first energy storage elastic component 26 to store energy. When the first energy storage elastic component 26 passes the equilibrium position, it releases energy. The release of energy by the first energy storage elastic component 26 causes the rotating component 25 to continue rotating. The rotation of the rotating component 25 drives the output shaft 4 to continue rotating. After the output shaft 4 passes the second critical position, the second energy storage elastic component 35 completes energy storage and releases energy. The release of energy by the first energy storage elastic component 26 and the second energy storage elastic component 35 drives the output shaft 4 to rotate to the closed position.

[0070] like Figure 2 , 3 As shown in Figure 6, the operating shaft 21 is arranged along the vertical direction of the housing 1. A groove structure is provided on the upper end face of the operating shaft 21. The groove structure is opposite to the operating hole 11 of the housing 1 and is used to drive the operating shaft 21 to rotate by a handle or other tool. A first gear 211 is arranged around the middle side wall of the operating shaft 21.

[0071] like Figure 2 , 3 As shown in Figures 7-9, the first transmission shaft 22 is disposed on one side of the operating shaft 21 along the vertical direction of the housing 1. A sector-shaped gear portion 221 is provided on the side of the first transmission shaft 22 facing the operating shaft 21. The sector-shaped gear portion 221 meshes with the first gear 211 of the operating shaft 21. A second gear 222 is provided in the middle of the first transmission shaft 22, surrounding the side wall of the first transmission shaft 22. That is, the second gear 222 is located below the gear portion 221. One end of the first transmission shaft 22 and the second transmission shaft 24 are inserted into each other. Figure 7 In this configuration, a square protrusion 223 is formed at the lower end of the first transmission shaft 22, and a square groove 241 is provided at the upper end of the second transmission shaft 24 to engage with the square protrusion 223. A third lever 242 is provided at the other end of the second transmission shaft 24, that is, the third lever 242 is located at the lower end of the second transmission shaft 24 and extends downward. The transmission plate 23 is movable in a direction perpendicular to the first transmission shaft 22. The side of the transmission plate 23 facing the first transmission shaft 22 has multiple teeth 231 for meshing with the second gear 222, so that the transmission plate 23 can perform linear reciprocating motion through the engagement of the teeth 231 with the second gear 222. A first lever 232 is provided at one end of the transmission plate 23 for engaging with the output shaft 4. Figure 8The first lever 232 faces downwards. When the output shaft 4 is in another direction, the orientation of the first lever 232 changes accordingly. Alternatively, the drive shaft can be an integral structure, in which case the drive shaft is linked to the operating shaft 21, the transmission plate 23, and the rotating component 25, respectively. The rotating component 25 and the transmission plate 23 are linked to the output shaft 4 to drive its rotation. Furthermore, as another embodiment, the first drive shaft 22 and the second drive shaft 24 can also be separate structures with their rotation axes parallel and spaced apart. That is, one end of the first drive shaft 22 is connected to the operating shaft 21, and the other end is connected to the second drive shaft 24. In other words, the rotation of the operating shaft 21 drives the first drive shaft 22 to rotate, and the first drive shaft 22 synchronously drives the second drive shaft 24 to rotate. The first drive shaft 22 and the transmission plate 23 are meshed, allowing precise control of the transmission position and distance. Moreover, the angle at which the transmission plate 23 drives the output shaft 4 to rotate when the brake is closed can be adjusted via the sector gear portion 221. Of course, the first drive shaft 22 and the transmission plate 23 can also be connected in other ways.

[0072] like Figure 2-5 As shown in Figure 10, the rotating member 25 is disposed at the lower part of the housing 1, and is rotatably connected to the housing 1 by the lower end of the rotating member 25. Spring slots 251 are respectively provided on opposite sides of the rotating member 25. One end of each first energy storage elastic member 26 is connected to the rotating member 25 through the spring slot 251, and the other end is connected to the side wall of the housing 1. Figure 2-5 In section 11, the first energy storage elastic element 26 is a spring. One end of the first energy storage elastic element 26 is rotatably connected to the housing 1, and the other end forms a closed-loop connecting part 261 for engaging with the spring slot 251. In the initial state, the axis of the rotating element 25 is eccentrically set with the axis of the first energy storage elastic element 26. The rotation of the rotating element 25 drives the spring slot 251 to rotate, causing the first energy storage elastic element 26 to rotate synchronously. In the initial stage of the rotation of the rotating element 25, the first energy storage elastic element 26 stores energy. When the rotation of the rotating element 25 makes the axis of the first energy storage elastic element 26 and the axis of the rotating element 25 lie on a straight line, it is the equilibrium position, i.e., the dead point position. At this time, the first energy storage elastic element 26 is compressed to its shortest length. After the rotating element 25 drives the first energy storage elastic element 26 to rotate past the equilibrium position, the first energy storage elastic element 26 releases energy and drives the rotating element 25 to rotate rapidly, thereby driving the output shaft 4 to rotate. The other end of the rotating component 25 is provided with a second stop 252, a third stop 253, and a fourth stop 254 protruding sequentially along the circumferential direction. The second stop 252 and the third stop 253 are respectively located on both sides of a spring retaining groove 251, and the fourth stop 254 is located near another spring retaining groove 251. Figure 2-5 In section 10, the second stop 252 and the fourth stop 254 are arranged along the same diameter of the rotating member 25, and the third stop 253 is located between the second stop 252 and the fourth stop 254. Figure 4 , 5The included angle between the third stop 253 and the second stop 252 is approximately 90°. In this embodiment, the protrusion height of the fourth stop 254 is higher than that of the second stop 252 and the third stop 253. The protrusion heights of the second stop 252 and the third stop 253 are the same. The second stop 252 and the third stop 253 are used to abut against the third lever 242 of the second drive shaft 24, and the third stop 253 and the fourth stop 254 are used to cooperate with the second lever 413 provided on the output shaft 4.

[0073] Preferably, in this embodiment, the output shaft 4 includes, as shown below: Figure 19-22 The first output shaft 41 and the second output shaft 42 shown are interlocked at one end, and the other ends of the first output shaft 41 and the second output shaft 42 are respectively used to be linked to the contact mechanism located on one side of the housing 1. The first output shaft 41 is used to drive the first drive structure, and the second output shaft 42 is used to drive the second drive structure and the second energy storage elastic element 35. Of course, the first output shaft 41 and the second output shaft 42 can also be an integral structure. The first drive structure and the second drive structure are respectively driven and connected to different areas of the output shaft 4. Preferably, the central axes of the first drive structure and the second drive structure are perpendicular to each other, and the central axis of the rotating part 25 of the first drive structure is perpendicular to the axis of the output shaft 4.

[0074] like Figure 19 , 20As shown, the first output shaft 41 includes an integrally formed rotating part and a circular shaft 411. One end of the circular shaft 411 is connected to the middle of one side of the rotating part. The outer diameter of the rotating part is larger than the outer diameter of the circular shaft 411. The side of the rotating part opposite to the circular shaft 411 is used for linkage connection with the contact mechanism. Preferably, the end face of the rotating part opposite to the circular shaft 411 is provided with a concave-convex mating surface for linkage connection with the contact mechanism. Further, an annular groove is provided on the side wall of the rotating part away from the circular shaft 411. The annular groove is used to support the rotation of the rotating part and the housing 1. A groove structure is provided at the end of the circular shaft 411 away from the rotating part for insertion and mating with the second output shaft 42. Preferably, the groove structure is a square groove. A protruding first stop 412 and second lever 413 are provided on the side wall of the first output shaft 41. The first stop 412 is used to cooperate with the first lever 232 of the transmission plate 23, and the second lever 413 is used to cooperate with the third stop 232 of the rotating part 25. 53. The fourth stop block 254 cooperates. In the figure, the first stop block 412 is a square boss set on the side wall of the circular shaft 411. The first stop block 412 is close to the rotating part and the protrusion height of the first stop block 412 is higher than the edge of the rotating part. A second lever 413 extending outward is provided on one side of the first stop block 412. The second lever 413 can be regarded as an extension plate formed by extending outward from the side wall of the first output shaft 41. The plate surface of the second lever 413 is parallel to the end face of the first output shaft 41. The end of the second lever 413 is provided with two inclined surfaces 414, so that the end of the second lever 413 is high in the middle and low on both sides. When the first output shaft 41 rotates, the two inclined surfaces 414 are conducive to cooperating with the third stop block 253 and the fourth stop block 254. Furthermore, an annular groove 416 is provided on the side of the first stop block 412 facing away from the second lever 413 to avoid the first lever 232 of the transmission plate 23, so as to avoid interfering with the cooperation between the first stop block 412 and the first lever 232.

[0075] like Figure 21 , 22 As shown, the second output shaft 42 includes an integrally formed rotating part and a square shaft 421. The rotating part of the second output shaft 42 is preferably the same as the rotating part of the first output shaft 41. One end of the square shaft 421 is connected to the middle of one side of the rotating part. The outer diameter of the rotating part is larger than the outer diameter of the square shaft 421. A concave-convex mating surface for linkage with the contact mechanism is provided on the side of the rotating part opposite to the square shaft 421. Preferably, an annular groove is provided on the side wall of the rotating part away from the square shaft 421. The annular groove is used to connect with the second drive structure. The other end of the square shaft 421 is inserted into the square groove 241 of the first output shaft 41. A circular shaft area 422 is provided in the area of ​​the square shaft 421 adjacent to the rotating part.

[0076] like Figure 12-15As shown, in a preferred embodiment of the second drive structure, the fixing member 31 and the locking assembly are included. The fixing member 31 is generally plate-shaped. A first clearance hole 311 for mounting on the output shaft 4 is provided in the middle of the fixing member 31. That is, the first clearance hole 311 is rotatably engaged with the annular groove of the rotating part in the second output shaft 42. A circular central groove 312 is provided on one side surface of the fixing member 31. The central groove 312 provides rotation space for the locking assembly. A first limiting groove 313 and a second limiting groove 314 are spaced apart circumferentially along the central groove 312. The central angles on both sides of the first limiting groove 313 are larger than the central angles of the second limiting groove 314. That is, the arc length of the first limiting groove 313 is greater than the arc length of the second limiting groove 314.

[0077] The locking assembly includes a clamping member 33, a sliding member 36, and a locking member 32. The clamping member 33, the sliding member 36, and the locking member 32 are all coaxially assembled on the second output shaft 42. Figure 12-16 As shown, the clamping member 33 is fixedly connected to the second output shaft 42 and can rotate with the second output shaft 42. The sliding member 36 is rotatably mounted on the second output shaft 42. The locking member 32, which is slidably mounted on the sliding member 36, is provided with a locking part 321. The locking member 32 can rotate around the output shaft 4 via the sliding member 36 and can slide relative to the sliding member 36 in the radial direction of the output shaft 4. That is, the locking member 32 can slide and engage with the sliding member 36 in either the first or the second direction. The second energy storage elastic member is connected between the clamping member 33 and the locking member 32, and drives the locking part 321 of the locking member 32 to lock with at least one of the two limiting grooves. The central angle of the locking part 321 is equal to the central angle of the second limiting groove 314. Thus, when the first limiting groove 313 engages with the locking part 321, there is a certain rotational margin. When the circuit is opened, it can first rotate a preset empty stroke. When the second limiting groove 314 engages with the locking part 321, there is no rotational margin.

[0078] When the locking part 321 engages with a limiting groove, the rotation of the output shaft 4 causes the second energy storage elastic element 35 to store energy through the clamping member 33, and the clamping member 33 drives the locking member 32 to slide in a first direction relative to the sliding member 36, so that the locking part 321 is separated from one limiting groove and unlocked. After unlocking, the second energy storage elastic element 35 releases energy and drives the clamping member 33 to drive the output shaft 4 to continue rotating. When the locking part 321 rotates to the position corresponding to another limiting groove, the locking member 32 is driven to slide in a second direction relative to the sliding member 36 and is locked with the other limiting groove. Specifically, the second energy storage elastic element 35 includes a rotating part coaxially mounted with the output shaft 4. The rotating part is connected to two elastic arms 351. A clamping element 33, a locking element 32, and a sliding element 36 are located between the two elastic arms 351. The two elastic arms 351 of the second energy storage elastic element 35 abut against the locking element 32 and the clamping element 33, respectively. During the rotation of the output shaft 4, the clamping element 33 and the locking element 32 cooperate to rotate around the second output shaft 42. During the mutual cooperation and rotation of the clamping element 33 and the locking element 32, the two elastic arms 351 simultaneously abut against the clamping element 33 and the locking element 32. When the locking element 32 engages with a limiting groove, the locking element 32 and the clamping element 33 are misaligned, causing the locking element 32 and the clamping element 36 to... 3. The two elastic arms 351 are respectively in contact with each other. At this time, the included angle between the two elastic arms 351 is widened, and the second energy storage elastic element 35 stores energy. When the output shaft 4 continues to rotate with the clamping element 33 to the first critical position or the second critical position, the clamping element 33 drives the locking element 32 to slide out from one of the limiting grooves to unlock. The elastic arm 351 in contact with the locking element 32 deforms. As the locking element 32 is driven to turn to the other limiting groove, the second energy storage elastic element 35 releases energy and can drive the clamping element 33 to drive the output shaft 4 to rotate. The elastic arm 351 in contact with the locking element 32 gradually returns to its original state to drive the locking part 321 to slide along the second direction to slide into the other limiting groove, thereby realizing the limiting lock.

[0079] like Figure 17As shown, the sliding member 36 is generally a square plate structure. A circular shaft hole 361, rotatably connected to the second output shaft 42, is provided in the middle of the sliding member 36. The circular shaft hole 361 rotatably engages with the circular shaft area 422 in the middle of the second output shaft 42. The locking member 32 is generally a rectangular plate structure. A locking part 321 protrudes outward from one edge of the locking member 32, that is, the locking part 321 is located on the shorter edge of the locking member 32. First blocking arms 323 are provided on both sides of the locking member 32 adjacent to the locking part 321, that is, first blocking arms 323 are provided on the longer edges of the locking member 32. A rectangular second blocking arm is provided in the middle of the locking member 32. The locking member 32 is slidably sleeved on the outer periphery of the sliding member 36 through the second clearance hole 322. The second clearance hole 322 provides a certain sliding space for the locking member 32, so that the locking part 321 of the locking member 32 slides along the direction close to or away from the central axis of the sliding member 36, i.e., the output shaft 4. The direction in which the locking part 321 is close to the sliding member 36 is the first direction, and the direction in which the locking part 321 is away from the sliding member 36 is the second direction. When the locking member 32 and the sliding member 36 are assembled together on the output shaft 4, the direction in which the locking part 321 is close to the central axis of the output shaft 4 is the first direction, and the direction in which the locking part 321 is away from the central axis of the output shaft 4 is the second direction.

[0080] like Figure 12-15 As shown in Figure 18, the clamping member 33 has an overall plate-shaped structure. A connecting shaft hole 334 for connecting to the second output shaft 42 is provided in the middle of the clamping member 33. The connecting shaft hole 334 is a square hole. Second locking arms 331, corresponding to the first locking arms 323, are provided on opposite sides of the clamping member 33. In this embodiment, the first locking arms 323 are formed by bending and extending the two side edges of the locking member 32 along an axial direction parallel to the second output shaft 42. The second locking arms 331 are formed by bending and extending the two side edges of the clamping member 33 along an axial direction parallel to the second output shaft 42. The two second locking arms 331 are located between the two first locking arms 323. The first locking arms 323 and the second locking arms 331 located on the same side can cooperate with the same elastic arm 351. An outwardly protruding protrusion 332 is provided on the other side of the clamping member 33. The opposite side edges of the protrusion 332 serve as mating parts 333. Figure 18 The middle mating part 333 is inclined, so that the side of the protrusion 332 away from the connecting shaft hole 334 has the largest width. The side of the protrusion 332 near the connecting shaft hole 334 is located between the two first locking arms 323. As the clamping member 33 rotates with the second output shaft 42, the mating part 333 abuts against the adjacent first locking arm 323, pushing the locking member to slide and unlock in the first direction.

[0081] like Figure 12-15As shown, the second energy storage elastic element 35 is sleeved on a copper sleeve 34. The copper sleeve 34, the clamping element 33, the locking element 32, and the fixing element 31 are sequentially sleeved on the second output shaft 42. The copper sleeve 34 presses against the clamping element 33. The second energy storage elastic element 35 is a torsion spring, preferably with the middle part of the torsion spring as the rotating part sleeved on the copper sleeve 34. The two elastic arms 351 of the torsion spring extend in opposite directions. Each elastic arm 351 can abut against the first locking arm 323 and the second locking arm 331 located on the same side. During the rotation of the second output shaft 42, the clamping element 33 moves with the second output shaft 42. When the output shaft 42 rotates, the locking part 321 of the locking member 32 is locked and limited. The locking member 32 and the pressing member 33 are misaligned, causing the first blocking arm 323 and the second blocking arm 331 located on the same side to be misaligned. One of the elastic arms 351 abuts against the first blocking arm 323, and the other elastic arm 351 abuts against the other second blocking arm 331. At this time, the second energy storage elastic member 35 stores energy. After the locking part 321 of the locking member 32 slides out of one of the limiting grooves and unlocks, the second energy storage elastic member 35 releases energy until the locking part 321 of the locking member 32 slides into the other limiting groove.

[0082] The specific cooperation process of this embodiment is provided as follows:

[0083] During the tripping process, the operating shaft 21 rotates, driving the first transmission shaft 22 to rotate. The second gear 222 of the first transmission shaft 22 meshes with several teeth 231 of the transmission plate 23, causing the transmission plate 23 to move along... Figure 2 The transmission plate moves horizontally from the closed position to the open position. Simultaneously, the first transmission shaft 22 drives the second transmission shaft 24 to rotate synchronously. The third lever 242 of the second transmission shaft 24 abuts against the second stop 252 of the rotating member 25, causing the rotating member 25 to rotate until it just passes the equilibrium position of a pair of first energy storage elastic elements 26. Under the energy release drive of the pair of first energy storage elastic elements 26, the rotating member 25 rotates rapidly, causing the primary energy storage mechanism 2 to rotate towards the first energy release position. Simultaneously, the rapid rotation of the rotating member 25, through the fourth stop 254 abutting against the second lever 413, drives the first output shaft 41 and the second output shaft 42 to rotate synchronously from the closed position towards the first critical position. After the first output shaft 41 and the second output shaft 42 rotate synchronously by the first rotation angle α (see...), the rotation continues. Figure 14The mating part 333 of the clamping member 33 presses against the first locking arm 323 of its adjacent locking member 32, causing the locking member 32 to rotate within the central groove 312 of the fixing member 31 around the center of the first clearance hole 311 (that is, the central axis of the second output shaft 42) until the locking part 321 of the locking member 32 has no rotational clearance with the first limiting groove 313. During this period, the second energy storage elastic member 35 does not store energy. When the locking part 321 is locked with the first limiting groove 313, the second locking arm 331 of the clamping member 33 continues to rotate with the second output shaft 42, causing the second energy storage elastic member 35 to store energy. The second locking arm 331 on one side of the clamping member 33 pushes an elastic arm 351 ( Figure 14 The elastic arm 351 on the left side and the second locking arm 331 on the left side are connected. At the same time, the mating part 333 on one side of the clamping member 33 presses against one of the first locking arms 323 of the locking member 32. Figure 14 The mating part 333 on the left side presses down on the first locking arm 323 on the left side, causing the locking member 32 to begin sliding in the first direction. The other first locking arm 323 of the locking member 32 abuts against the other elastic arm 351. Figure 14 (The first locking arm 323 on the right side abuts against the elastic arm 351 on the right side). At this time, the circumferential distance between the two elastic arms 351 increases the energy storage. At the same time, because the locking member 32 slides along the first direction, the locking part 321 separates from the first limiting groove 313, and the elastic arm 351 pressed by the first locking arm 323 undergoes elastic deformation.

[0084] Subsequently, when the energy storage mechanism 2 rotates to the first energy release position (i.e., the first energy storage elastic element 26 completes energy release when the circuit is opened), the first energy storage elastic element 26 drives the output shaft 4 to rotate to the first critical position. The second energy storage elastic element 35 completes energy storage and begins to release energy. The other elastic arm 351 of the second energy storage elastic element 35 abuts against the other first locking arm 323 of the locking element 32 (the elastic arm 351 on the right side and the first locking arm 323 on the right side), causing the locking element 32 to quickly rotate towards the second limiting groove 314 under the energy release action of the second energy storage elastic element 35. During this process, the other elastic arm 351 gradually resets, and the locking element 32 slides along the second direction by pushing the other first locking arm 323. Figure 14 The elastic arm 351 on the right pushes the first blocking arm 323 on the right until the locking part 321 is locked with the second limiting groove 314. At this time, the first output shaft 41 and the second output shaft 42 rotate synchronously at a certain angle, which is the second rotation angle between the output shaft 4 and the first critical position to the open position. Figure 14 In the diagram, β represents the second rotation angle. At this time, the first stop 412 of the first output shaft 41 abuts against the first lever 232 of the transmission plate 23. The output shaft 4 rotates to the open position, realizing two rotations of the output shaft, which in turn transmits the power to the contact mechanism to increase the opening distance.

[0085] During the closing process, the operation shaft 21 rotates, driving the first transmission shaft 22 to rotate. The second gear 222 of the first transmission shaft 22 meshes with several teeth 231 of the transmission plate 23, causing the transmission plate 23 to move from the open position to the closed position. The first lever 232 of the transmission plate 23 moves and abuts against the first stop 412 of the first output shaft 41, causing the first output shaft 41 to drive the second output shaft 42 to rotate by a certain angle. That is, the output shaft 4 rotates from the open position to the second critical position. At this time, the rotation angle of the output shaft 4 is the third rotation angle. Figure 15 In the diagram, γ represents the third rotation angle, and the second energy storage elastic element 35 stores energy. At the same time, the third lever 242 of the second transmission shaft 24 abuts against the third stop 253 of the rotating element 25, causing the rotating element 25 to rotate until the rotating element 25 drives the first energy storage elastic element 26 to rotate past the equilibrium position of the pair of first energy storage elastic elements 26. After the first energy storage elastic element 26 rotates past the equilibrium position and releases energy, the rotating element 25 rotates rapidly under the action of the energy release of the pair of first energy storage elastic elements 26, so that the third stop 253 abuts against the second lever 413 of the first output shaft 41, which also drives the first output shaft 41 and the second output shaft 42 to rotate toward the second critical position.

[0086] During the process of the output shaft 4 rotating from the closed position to the second critical position, since the locking part 321 of the locking member 32 and the second limiting groove 314 have no rotational margin, the first output shaft 41 and the second output shaft 42 drive the clamping member 33 to rotate when they rotate synchronously. The rotation of the clamping member 33 overcomes the elastic force of the second energy storage elastic member 35 and stores energy for the second energy storage elastic member 35. That is, when the locking part 321 and the second limiting groove 314 are engaged, the second blocking arm 331 of the clamping member 33 is misaligned with the first blocking arm 323 of the locking member 32, and one side of the first blocking arm 323 of the locking member 32 abuts against one elastic arm 351 of the second energy storage elastic member 35. Figure 15 The first stop arm 323 on the left abuts against the elastic arm 351 on the left, and the other elastic arm 351 is pressed down by the second stop arm 331 located on the other side for energy storage. Figure 15 The elastic arm 351 on the right side and the second locking arm 331 on the right side), at the same time, a mating part 333 of the clamping member 33 presses against the first locking arm 323 of its adjacent locking member 32 (that is, Figure 15 The right-side mating part 333 and the right-side first locking arm 323) cause the locking member 32 to slide and engage with the sliding member 36 along the first direction, that is, to slide towards the central axis of the second output shaft 42 until the locking part 321 separates from the second limiting groove 314 and unlocks.

[0087] After the output shaft 4 rotates to the second critical position, the second energy storage elastic element 35 releases energy, and the first energy storage elastic element 26 continues to release energy, causing the first output shaft 41 and the second output shaft 42 to continue rotating in the closing direction. As the second energy storage elastic element 35 releases energy, one elastic arm 351 of the second energy storage elastic element 35 abuts against the first locking arm 323 of the locking element 32 (that is... Figure 15 The elastic arm 351 on the left side abuts against the first blocking arm 323 on the left side, causing the locking member 32 to rotate rapidly under the energy release action of the second energy storage elastic member 35. At the same time, the elastic arm 351 gradually resets and pushes the first blocking arm 323 to make the locking member 32 slide along the second direction until the locking part 321 and the first limiting groove 313 limit each other to achieve locking. At this time, the first output shaft 41 and the second output shaft 42 have been driven to the closed position by the primary energy storage mechanism 2. The primary energy storage mechanism 2 is located in the second energy release position (i.e., the position where the first energy storage elastic member 26 completes energy release when the circuit is closed). The angle at which the output shaft 4 rotates from the second critical position to the closed position is the fourth angle. Figure 15 In the middle, δ represents the fourth turning angle.
