Description

Technical Field

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

[0002] As an important support for the development of modern society, economy and people's livelihood, power transmission and distribution line system plays an irreplaceable role. As an important component carrier in the power transmission and distribution line system, the transfer switch plays an important role, especially in occasions where uninterrupted, reliable, stable and continuous power output is required, such as hospitals, intelligent buildings, data centers, power plants, banks and important infrastructure.

[0003] In existing technologies, transfer switches are mostly of two-position and three-position types. Two-position transfer switches switch between two states: the primary power supply is closed (while the backup power supply is open) and the backup power supply is closed (while the primary power supply is open), ensuring continuous, stable, and reliable power output from transmission and distribution lines. Three-position transfer switches, in addition to achieving the working states of two-position transfer switches, can also simultaneously achieve a double-open state (i.e., both the primary and backup power supplies are open). Existing technologies such as CN111986938A, CN109786146A, CN109686598A, CN113838694A, and CN113611553A disclose different types of transfer switches.

[0004] The existing technology has the following problems with the operating mechanism of the changeover switch:

[0005] (1) The overall layout is unreasonable and occupies a large space.

[0006] (2) An operating mechanism that can achieve three-position switching and whose switching speed is independent of the speed of the manual operating mechanism and the automatic operating mechanism has a complex transmission structure, or a relatively simple function with low reliability, or an unreasonable layout that results in a large size.

[0007] (3) After the energy storage mechanism releases energy, it drives other transmission mechanisms to indirectly drive the main shaft to rotate. There are many transmission components, the mechanism is complex and occupies a large space.

[0008] (4) Automatic operating mechanisms use motor transmission, which is slow, or use electromagnetic mechanisms, but require complex transmission mechanisms.

[0009] (5) The operating mechanism lacks a limit mechanism for dual-position switching, resulting in poor reliability.

[0010] (6) When the spindle is in the main power supply closed position and the backup power supply closed position, there is no limiting structure for the spindle, and it is impossible to prevent other mechanisms outside the operating mechanism from driving the spindle to flip. Summary of the Invention

[0011] The purpose of this invention is to overcome at least one defect of the prior art and provide an operating mechanism for a changeover switch.

[0012] To achieve the above objectives, the present invention adopts the following technical solution:

[0013] An operating mechanism for a changeover switch includes a bracket, an energy storage mechanism for driving a main shaft, a manual operating mechanism, and an automatic operating mechanism. The energy storage mechanism includes a first energy storage mechanism, a second energy storage mechanism, and a flipping component. The flipping component rotates to drive the first or second energy storage mechanism to store energy first. After the first or second energy storage mechanism passes a balance position, it releases energy to drive the main shaft to rotate rapidly and switch positions. The bracket includes a first side plate and a second side plate arranged at relative intervals. The first energy storage mechanism, the second energy storage mechanism, and the flipping component are disposed between the first and second side plates. The main shaft passes through the first and second side plates. The flipping component is rotatably mounted on the main shaft. The automatic operating mechanism includes a first electromagnetic mechanism and a second electromagnetic mechanism, which are symmetrically arranged on both sides below the flipping component to drive its rotation. The manual operating mechanism includes a toggle component connected to the flipping component and rotatably disposed between the first and second side plates above the flipping component to drive its rotation.

[0014] Preferably, the flipping component is rotatably configured and has a first arc groove and a second arc groove. The first energy storage mechanism and the second energy storage mechanism each include a linkage mechanism and an energy storage spring. The linkage mechanism includes a pulling plate and a receiving plate. One end of the energy storage spring is rotatably configured and the other end is connected to one end of the pulling plate. The other end of the pulling plate is hinged to the receiving plate through a linkage shaft. The receiving plate is rotatably configured and connected to the main shaft. The linkage shafts of the first energy storage mechanism and the second energy storage mechanism are respectively installed in the first arc groove and the second arc groove of the flipping component.

[0015] The rotation of the flipping component drives the linkage shaft of the first energy storage mechanism through the first arc groove, thereby causing the linkage mechanism of the first energy storage mechanism to move. This causes the energy storage spring of the first energy storage mechanism to store energy first and release energy after passing the equilibrium position. The release of energy by the energy storage spring of the first energy storage mechanism drives the linkage mechanism of the first energy storage mechanism to move, thereby driving the main shaft to rotate.

[0016] Alternatively, the rotation of the flipping component drives the linkage shaft of the second energy storage mechanism through the second arc groove, thereby causing the linkage mechanism of the second energy storage mechanism to move. This causes the energy storage spring of the second energy storage mechanism to store energy first and then release energy after passing the equilibrium position. The release of energy by the energy storage spring of the second energy storage mechanism drives the linkage mechanism of the second energy storage mechanism to move, thereby driving the main shaft to rotate.

[0017] Preferably, the flipping component can rotate to a first position, a middle position, and a second position, respectively, to drive the main shaft to rotate to the main power supply closed position, the dual-open position, and the backup power supply closed position; when the flipping component rotates from the middle position to the first position, or from the first position to the middle position, the first energy storage mechanism is driven to store energy first and release energy after passing the equilibrium position, driving the main shaft to rotate to the corresponding main power supply closed position or dual-open position; when the flipping component rotates from the middle position to the second position, or from the second position to the middle position, the second energy storage mechanism is driven to store energy first and release energy after passing the equilibrium position, driving the main shaft to rotate to the corresponding backup power supply closed position or dual-open position.

[0018] Preferably, the driven plate is provided with a driven plate rotation hole, and the driven plate is sleeved on the main shaft through the driven plate rotation hole. The flipping member is located between the driven plate of the first energy storage mechanism and the driven plate of the second energy storage mechanism. A driven plate driving part is provided in the driven plate rotation hole, and a main shaft linkage part is provided on the main shaft. The driven plate can rotate around the main shaft, and after the driven plate contact and limit the main shaft, the driven plate drives the main shaft to rotate.

[0019] Preferably, a first energy storage spring fixing shaft and a second energy storage spring fixing shaft are provided between the first side plate and the second side plate, and one end of the energy storage spring of the first energy storage mechanism or the second energy storage mechanism is rotatably connected to the first energy storage spring fixing shaft and the second energy storage spring fixing shaft, respectively.

[0020] Preferably, the first electromagnetic mechanism and the second electromagnetic mechanism each include an electromagnetic component and a movable rod connected to the electromagnetic component. The movable rod is provided with a movable rod driving part. The two movable rods of the first electromagnetic mechanism and the second electromagnetic mechanism are respectively a first movable rod and a second movable rod. The two movable rod driving parts of the first movable rod and the second movable rod are respectively a first movable rod driving part and a second movable rod driving part.

[0021] When the flipping component is in the middle position, the third linkage part and the fourth linkage part are located between the two moving rod driving parts of the first moving rod and the second moving rod. When the first electromagnetic mechanism is energized, it can drive the first moving rod to move. The first moving rod driving part drives the third linkage part to rotate the flipping component from the middle position to the first position of the flipping component. Alternatively, when the second electromagnetic mechanism is energized, it can drive the second moving rod to move. The second moving rod driving part drives the fourth linkage part to rotate the flipping component from the middle position to the second position of the flipping component.

[0022] When the flipping component is in the first position of the flipping component, the third linkage part is located between the two moving rod driving parts, and the fourth linkage part rotates out between the two moving rod driving parts. When the second electromagnetic mechanism is energized, it can drive the second moving rod to move. The second moving rod driving part drives the third linkage part to drive the flipping component to rotate from the first position of the flipping component to the middle position of the flipping component.

[0023] When the flipping component is in the second position, the fourth linkage part is located between the two moving rod driving parts, and the third linkage part rotates out between the two moving rod driving parts. When the first electromagnetic mechanism is energized, it can drive the first moving rod to move. The first moving rod driving part drives the fourth linkage part to rotate the flipping component from the second position to the middle position of the flipping component.

[0024] Preferably, the electromagnetic components of both the first and second electromagnetic mechanisms include a moving iron core and a movable rod mounting plate fixedly connected to the moving iron core. The movable rod is rotatably mounted on the movable rod mounting plate, and a movable rod spring is connected to the movable rod. The movable rod spring drives the movable rod to rotate until it is limited and fixed to the movable rod mounting plate. The outer side of the hook structure is provided with a hook portion slope. When the first and second electromagnetic mechanisms are de-energized and the movable rod is reset, the third or fourth linkage part located on the reset path of the movable rod acts on the hook portion slope, causing the movable rod to rotate to avoid the third or fourth linkage part.

[0025] Preferably, the actuating element and the flipping element are linked together. When the actuating element rotates to the first position, the middle position, and the second position, it drives the flipping element to rotate to the first position, the middle position, and the second position, respectively. When the flipping element rotates to the first position, the middle position, and the second position, it drives the actuating element to rotate to the first position, the middle position, and the second position, respectively.

[0026] Preferably, the actuating element is rotatably disposed between the first side plate and the second side plate of the bracket. A first limiting shaft and a second limiting shaft are provided between the first side plate and the second side plate. When the actuating element rotates to the first position, it is limited by the first limiting shaft, and when the actuating element rotates to the second position, it is limited by the second limiting shaft.

[0027] Preferably, when the actuating element rotates to the first position and the second position, the main shaft locking mechanism is driven to lock the main shaft, preventing the main shaft from rotating to the split position. When the actuating element rotates to the middle position, the main shaft locking mechanism is driven to release the lock on the main shaft.

[0028] Preferably, the spindle locking mechanism includes a first lever and a second lever, the first ends of the first lever and the second lever are rotatably disposed, a first elastic element is connected between the second ends of the first lever and the second lever, the actuating element is provided with a third actuating part for driving the first lever and the second lever, the third actuating part is located between the second ends of the first lever and the second lever, the spindle is provided with a first locking part and a second locking part, the side of the first lever with the first lever locking part and the side of the second lever with the second lever locking part are arranged at intervals relative to each other and are located on both sides of the spindle respectively;

[0029] When the actuating element moves to the first position, it drives the second lever to move away from the main shaft and avoid the first lever, so that the first elastic element drives the first lever to move the first lever locking part closer to the main shaft. When the main shaft rotates to the main power closed position, the first locking part of the main shaft locks with the first lever locking part, so that the main shaft cannot rotate to the double split position.

[0030] When the actuating element moves to the second position, it drives the first lever to move away from the main shaft and avoid the second lever, so that the first elastic element drives the second lever to move the second lever locking part closer to the main shaft. When the main shaft rotates to the backup power on position, the second locking part of the main shaft locks with the second lever locking part, so that the main shaft cannot rotate to the double split position.

[0031] When the actuating member rotates from the first position to the middle position, it drives the first lever to overcome the force of the first elastic member and move the locking part of the first lever away from the main shaft, releasing the locking engagement with the first locking part of the main shaft, and the first elastic member drives the second lever to reset; when the actuating member rotates from the second position to the middle position, it drives the second lever to overcome the force of the first elastic member and move the locking part of the second lever away from the main shaft, releasing the locking engagement with the second locking part of the main shaft, and the first elastic member drives the first lever to reset.

[0032] Preferably, the first lever, the second lever, and the first elastic element are located on the outside of the second side plate, and the third actuating part on the actuating element extends from the second side plate sliding groove on the second side plate to the space between the second end of the first lever and the second end of the second lever.

[0033] Preferably, it further includes a toggle element limiting mechanism, the toggle element limiting mechanism including a first limiting plate, a second limiting plate, a first limiting plate reset member and a second limiting plate reset member, the first limiting plate and the second limiting plate are rotatably disposed, the first limiting plate reset member is connected to the first limiting plate and drives the first limiting plate to rotate away from the toggle element to avoid the toggle element, the second limiting plate reset member is connected to the second limiting plate and drives the second limiting plate to rotate away from the toggle element to avoid the toggle element;

[0034] When the flipping component rotates from the first position to the middle position, the actuating component rotates from the first position to the middle position. The flipping component drives the first energy storage mechanism to store energy and pass the equilibrium position. The first energy storage mechanism drives the first limiting plate to move towards the actuating component, and the limiting part of the first limiting plate limits the actuating component to the middle position, so that the actuating component cannot continue to rotate to the second position. After passing the equilibrium position, the first energy storage mechanism releases energy and drives the main shaft to rotate to the double position. The first energy storage mechanism avoids the first limiting plate, and the first limiting plate reset component drives the first limiting plate to move and release the limitation on the actuating component.

[0035] When the flipping component rotates from the second position to the middle position, the actuating component rotates from the second position to the middle position. The flipping component drives the second energy storage mechanism to store energy and pass the equilibrium position. The second energy storage mechanism drives the second limiting plate to move towards the actuating component, and the limiting part of the second limiting plate limits the actuating component to the middle position, preventing the actuating component from continuing to rotate towards the first position. After passing the equilibrium position, the second energy storage mechanism releases energy, driving the main shaft to rotate to the double position. The second energy storage mechanism avoids the second limiting plate, and the second limiting plate reset component drives the second limiting plate to move and release the limitation on the actuating component.

[0036] Preferably, the driven plates of the first energy storage mechanism and the second energy storage mechanism are respectively a first driven plate and a second driven plate. Both the first driven plate and the second driven plate are provided with a limit plate driving part, which is used to drive the first limit plate and the second limit plate respectively. The first driven plate and the second driven plate are mounted on the main shaft. The flipping member is located between the first driven plate and the second driven plate. The actuating member limiting mechanism is arranged between the first side plate and the second side plate. The first limit plate and the second limit plate are respectively arranged above the first driven plate and the second driven plate. The actuating member is arranged above the flipping member. The two sides of the actuating member are respectively provided with a first actuating part and a second actuating part, which are used to limit and cooperate with the first limit plate and the second limit plate respectively.

[0037] Preferably, the first side plate and the second side plate are mounted on the base. Both the left and right sides of the first side plate and the second side plate are provided with electromagnetic component mounting notches corresponding to the electromagnetic components of the first electromagnetic mechanism and the second electromagnetic mechanism. The electromagnetic components of the first electromagnetic mechanism and the second electromagnetic mechanism are mounted on the base and are correspondingly mounted at the electromagnetic component mounting notches. The moving rods of the first electromagnetic mechanism and the second electromagnetic mechanism extend into the first side plate and the second side plate and move in the left and right direction to drive the flip plate to rotate. The actuating member is provided above the flip plate, and the actuating member is provided with an actuating member driving part for manual operation.

[0038] Preferably, the spindle includes a first spindle connecting section, a spindle mounting section, a second spindle connecting section, and a spindle output section arranged sequentially. The first spindle connecting section and the second spindle connecting section correspond to the spindle holes on the first side plate and the second side plate, respectively. The spindle mounting section is located between the first side plate and the second side plate and is used to install the driven plate and the flipping component of the first energy storage mechanism and the second energy storage mechanism. The spindle output section is used to connect with the switch contact system.

[0039] The operating mechanism of the changeover switch of the present invention includes an energy storage mechanism, a manual operation mechanism, and an automatic operation mechanism. The energy storage mechanism includes a first energy storage mechanism, a second energy storage mechanism, and a flipping component. The flipping component is used to drive the first energy storage mechanism and the second energy storage mechanism to store energy first and release energy after passing the equilibrium position to drive the main shaft to rotate. The flipping component does not rotate with the main shaft but is rotatably mounted on the main shaft, making the overall structure compact and facilitating the arrangement of the first electromagnetic mechanism, the second electromagnetic mechanism, and the toggle component.

[0040] Furthermore, the automatic operating mechanism of the operating mechanism of the present invention adopts a first electromagnetic mechanism and a second electromagnetic mechanism, which is faster than the motor operation and improves the switching speed of the changeover switch.

[0041] Furthermore, when the flipping component rotates, it drives the corresponding connecting shaft through one of the two end sidewalls of the first or second circular arc groove, thereby moving the linkage mechanism of the first or second energy storage mechanism. This causes the corresponding energy storage spring to store energy first and release it after passing the equilibrium position, driving the linkage mechanism to drive the main shaft to rotate. The connecting shaft slides to the other end of the first and second circular arc grooves. Thus, during the energy storage process, the main shaft does not move. After the energy storage mechanism releases energy, it drives the main shaft to rotate quickly to switch the power supply. The switching speed of the automatic transfer switch is independent of the speed of the manual and automatic operating mechanisms, ensuring that the operating mechanism can quickly drive the main shaft to switch the power supply, reducing the burning of the switch contact system by the electric arc, and improving the performance and reliability of the transfer switch.

[0042] In addition, a toggle limiting mechanism is provided. When the first energy storage mechanism and the second energy storage mechanism reach the equilibrium position, the toggle limiting mechanism is driven to limit the toggle to the middle position of the toggle and the flipping to the middle position of the flipping. Then, the toggle limiting mechanism is released by the energy release action of the first energy storage mechanism and the second energy storage mechanism to avoid the toggle limiting mechanism, and the toggle can move to the first position and the second position of the toggle, thereby improving the reliability and safety of the operation mechanism.

Detailed Implementation

[0079] The specific embodiments of the present invention are further described below with reference to the accompanying drawings. The scope of protection of the present invention is not limited to the description of the following embodiments.

[0080] A changeover switch typically includes an operating mechanism and a switch contact system (not shown in the figure). The operating mechanism is connected to the switch contact system via a spindle 6. The switch contact system is connected to a main power supply and a backup power supply. The rotation of the spindle 6 causes the switch contact system to switch between main power supply to power the load and backup power supply to power the load.

[0081] For a two-position changeover switch, the operating mechanism drives the main shaft 6 to rotate between two positions: the main power supply closed position and the backup power supply closed position. When the main shaft 6 rotates to the main power supply closed position, it switches the switch contact system to the main power supply on state; when it rotates to the backup power supply closed position, it switches the switch contact system to the backup power supply on state. For a three-position changeover switch, the operating mechanism drives the main shaft 6 to rotate between three positions: the main power supply closed position, the double open position, and the backup power supply closed position. When the main shaft 6 rotates to these positions, it switches the switch contact system to the main power supply on state, the state where both the main power supply and backup power supply are off, or the state where the backup power supply is on, respectively.

[0082] Refer to this application Figure 1 , Figure 2a The operating mechanism of the changeover switch includes an energy storage mechanism connected to the main shaft 6, as well as a manual operating mechanism and / or an automatic operating mechanism. The energy storage mechanism includes a first energy storage mechanism 1, a second energy storage mechanism 2, and a flipping component 3. The flipping component 3 is rotatably configured. The rotation of the flipping component 3 drives the first energy storage mechanism 1 or the second energy storage mechanism 2 to store energy first. After the first energy storage mechanism 1 or the second energy storage mechanism 2 passes the equilibrium position (dead point position), the first energy storage mechanism 1 or the second energy storage mechanism 2 releases energy to drive the main shaft 6 to rotate rapidly and switch positions. The automatic operating mechanism is used to remotely control the energy storage mechanism to achieve power switching and disconnection. The manual operating mechanism is used to manually drive the energy storage mechanism to achieve power switching and disconnection. The first energy storage mechanism 1 and the second energy storage mechanism 2 have the same structure; one is used for switching the main power supply on and off, and the other is used for switching the backup power supply on and off.

[0083] For example, in a two-position changeover switch, the flipper 3 can rotate between the first position and the second position to drive the main shaft 6 to rotate between the main power supply closed position and the backup power supply closed position. When the flipper 3 moves from the second position to the first position, it drives the first energy storage mechanism 1 to store energy and release energy after passing the equilibrium position (dead point position), directly or indirectly driving the main shaft 6 to rotate to the main power supply closed position. When the flipper 3 moves from the first position to the second position, it drives the second energy storage mechanism 2 to store energy and release energy after passing the equilibrium position (dead point position), directly or indirectly driving the main shaft 6 to rotate to the backup power supply closed position.

[0084] For a three-position changeover switch, the flipper 3 can rotate to a first position, a middle position, and a second position, respectively, which are used to drive the main shaft 6 to rotate to the main power closed position, the dual open position, and the backup power closed position. When the flipper 3 rotates from the middle position to the first position, or from the first position to the middle position, it drives the first energy storage mechanism 1 to store energy first and release energy after passing the equilibrium position (dead point position), directly or indirectly driving the main shaft 6 to rotate to the corresponding main power closed position or dual open position. When the flipper 3 rotates from the middle position to the second position, or from the second position to the middle position, it drives the second energy storage mechanism 2 to store energy first and release energy after passing the equilibrium position (dead point position), directly or indirectly driving the main shaft 6 to rotate to the corresponding backup power closed position or dual open position. This is the prior art in this field.

[0085] like Figure 1 , Figure 2a As shown, this embodiment of the operating mechanism includes a housing 10 and an energy storage mechanism disposed within the housing 10. The housing 10 includes a base 101 and a support 102 mounted on the base 101. The support 102 includes a first side plate 103 and a second side plate 104 spaced apart from each other, connected by several fixed shafts. The energy storage mechanism includes a first energy storage mechanism 1, a second energy storage mechanism 2, and a flipping component 3. The first energy storage mechanism 1, the second energy storage mechanism 2, and the flipping component 3 are disposed between the first side plate 103 and the second side plate 104. The first energy storage mechanism 1 and the second energy storage mechanism 2 have identical structures and are symmetrically arranged on both sides of the flipping component 3. A main shaft 6 is rotatably mounted and passes through the middle of the first side plate 103 and the second side plate 104. The operating mechanism also includes a manual operating mechanism and an automatic operating mechanism. The automatic operating mechanism of this embodiment includes a first electromagnetic mechanism 7 and a second electromagnetic mechanism 8, mounted on the base 101 and symmetrically arranged on both sides of the flipping component 3, for driving the flipping component 3 to rotate. The manual operating mechanism of this embodiment includes a toggle member 4, which is connected to and rotatably disposed between the first side plate 103 and the second side plate 104 to drive the rotating member 3 to rotate. In other embodiments, the housing 10 may also be provided with a top cover to cover the bracket 102; or the bracket 102 may be a relatively closed housing structure; or the base 101 may not be provided, and the first electromagnetic mechanism 7 and the second electromagnetic mechanism 8 may also be mounted on the bracket 102, etc.

[0086] One improvement in this application lies in the overall layout of the operating mechanism, such as... Figure 1 , Figure 2aAs shown, the flipping component 3 is rotatably mounted on the main shaft 6, which passes through the middle of the first side plate 103 and the second side plate 104. The first electromagnetic mechanism 7 and the second electromagnetic mechanism 8 are symmetrically arranged on the lower sides of the flipping component 3. The manual operation mechanism includes a toggle component 4, which is connected to the flipping component 3 and rotatably mounted between the first side plate 103 and the second side plate 104, located above the flipping component 3.

[0087] The operating mechanism of this embodiment includes an energy storage mechanism, a manual operating mechanism, and an automatic operating mechanism. The energy storage mechanism includes a first energy storage mechanism 1, a second energy storage mechanism 2, and a flipping component 3. The flipping component 3 is used to drive the first energy storage mechanism 1 and the second energy storage mechanism 2 to store energy first and release energy after passing the equilibrium position to drive the main shaft 6 to rotate. The flipping component 3 does not rotate with the main shaft 6 but is rotatably mounted on the main shaft 6, making the overall structure compact and facilitating the arrangement of the first electromagnetic mechanism 7, the second electromagnetic mechanism 8, and the actuating component 4.

[0088] like Figure 2a , Figure 2b As shown, another improvement of this application lies in the structural design of the energy storage mechanism, providing a new energy storage mechanism. The energy storage mechanism includes a first energy storage mechanism 1, a second energy storage mechanism 2, and a flipping component 3. The flipping component 3 is rotatably disposed and is provided with a first arc groove 31 and a second arc groove 32. The first energy storage mechanism 1 and the second energy storage mechanism 2 each include a linkage mechanism and an energy storage spring. The linkage mechanism includes a pulling plate and a driven plate. One end of the energy storage spring is rotatably disposed, and the other end is connected to one end of the pulling plate. The other end of the pulling plate is hinged to the driven plate through a linkage shaft. The driven plate is rotatably disposed and is directly or indirectly connected to the main shaft 6. The linkage shafts of the first energy storage mechanism 1 and the second energy storage mechanism 2 are respectively installed in the first arc groove 31 and the second arc groove 32 of the flipping component 3. The connecting shafts of the first energy storage mechanism 1 and the second energy storage mechanism 2 can slide within the corresponding first arc groove 31 and second energy storage mechanism 2. When the flipping member 3 rotates, it drives the corresponding connecting shaft through one of the two end side walls of the first arc groove 31 or the second arc groove 32, causing the connecting mechanism of the first energy storage mechanism 1 or the second energy storage mechanism 2 to move. This causes the corresponding energy storage spring to store energy first and release energy after passing the equilibrium position, driving the connecting mechanism to drive the main shaft 6 to rotate. The connecting shaft slides to the other end of the first arc groove 31 and the second arc groove 32. The two end side walls of the first arc groove 31 drive the connecting shaft to move in different directions.

[0089] The rotation of the flipping component 3 drives the connecting shaft of the first energy storage mechanism 1 through the first arc groove 31, thereby causing the connecting mechanism of the first energy storage mechanism 1 to move. This causes the energy storage spring of the first energy storage mechanism 1 to store energy first and then release energy after passing the equilibrium position. The release of energy from the energy storage spring of the first energy storage mechanism 1 drives the connecting mechanism of the first energy storage mechanism 1 to move, thereby causing the main shaft 6 to rotate. Alternatively, the rotation of the flipping component 3 drives the connecting shaft of the second energy storage mechanism 2 through the second arc groove 32, thereby causing the connecting mechanism of the second energy storage mechanism 2 to move. This causes the energy storage spring of the second energy storage mechanism 2 to store energy first and then release energy after passing the equilibrium position. The release of energy from the energy storage spring of the second energy storage mechanism 2 drives the connecting mechanism of the second energy storage mechanism 2 to rotate the main shaft 6.

[0090] like Figure 2a , Figure 2b , Figure 9a , Figure 9b As shown, the flipping component 3 includes a first arcuate groove 31 and a second arcuate groove 32. In this embodiment, the flipping component 3 is rotatably mounted on the main shaft 6 and rotates around the main shaft 6. Of course, the main shaft 6 can also be mounted on other rotating shafts instead of the main shaft 6. The linkage mechanisms of the first energy storage mechanism 1 and the second energy storage mechanism 2 are the first linkage mechanism 12 and the second linkage mechanism 22, respectively. The energy storage springs of the first energy storage mechanism 1 and the second energy storage mechanism 2 are the first energy storage spring 11 and the second energy storage spring 21, respectively. The connecting shafts of the first energy storage mechanism 1 and the second energy storage mechanism 2 are the first connecting shaft 123 and the second connecting shaft 223, respectively.

[0091] The first linkage mechanism 12 has a pull plate and a driven plate, which are respectively a first driven plate 121 and a first pull plate 122. The first driven plate 121 is rotatably set and connected to the main shaft 6. The first driven plate 121 is hinged to one end of the first pull plate 122 through the first connecting shaft 123. The other end of the first pull plate 122 is connected to one end of the first energy storage spring 11. The other end of the first energy storage spring 11 is connected to the first energy storage spring fixing shaft 1023 of the bracket 102. The first connecting shaft 123 is movably installed in the first arc groove 31 of the flipping part 3. The flipping component 3 drives the first connecting rod shaft 123 through one end sidewall of the first arc-shaped sliding groove 31, causing the first driven plate 121 and the first pulling plate 122 to rotate. This causes the first energy storage spring 11 to store energy first. After the first energy storage spring 11 passes the equilibrium position, it releases energy and drives the first driven plate 121 to rotate through the first pulling plate 122 and the first connecting rod shaft 123. The first driven plate 121 then drives the main shaft 6 to rotate. The equilibrium position is as follows: Figure 3b In the example, the rotation axis of the first energy storage spring 11, the first driven plate 121 and the first connecting rod shaft 123 are in the same straight line. After the first energy storage spring 11 releases energy, the first connecting rod shaft 123 slides to the other side wall of the first arc groove 31.

[0092] The structure of the second linkage mechanism 22 is similar to that of the first linkage mechanism 12. The pulling plate and the driven plate of the second linkage mechanism 22 are the second driven plate 221 and the second pulling plate 222, respectively. The second driven plate 221 is hinged to one end of the second pulling plate 222 through the second linkage shaft 223. The other end of the second pulling plate 222 is connected to one end of the second energy storage spring 21. The other end of the second energy storage spring 21 is connected to the second energy storage spring fixing shaft 1024 of the bracket 102. The second linkage shaft 223 is movably installed in the second arc groove 32 of the flipping part 3. The flipping component 3 drives the second connecting rod shaft 223 through one end sidewall of the second arc groove 32, causing the second driven plate 221 and the second pulling plate 222 to rotate, so that the second energy storage spring 21 stores energy first. After the second energy storage spring 21 passes the equilibrium position, the second energy storage spring 21 releases energy and drives the second driven plate 221 to rotate through the second pulling plate 222 and the second connecting rod shaft 223. After the driven part 1213 of the driven plate contacts and limits the main shaft linkage part 61, the second driven plate 221 drives the main shaft 6 to rotate. After the second energy storage spring 21 releases energy, the second connecting rod shaft 223 slides to the other end sidewall of the second arc groove 32.

[0093] The driven plates of the first energy storage mechanism 1 and the second energy storage mechanism 2, namely the first driven plate 121 and the second driven plate 221, can be directly or indirectly connected to the main shaft 6. In this embodiment, both the first energy storage mechanism 1 and the second energy storage mechanism 2 are provided with driven plate rotation holes 1212, and driven plate driving parts 1213 are provided in the driven plate rotation holes 1212. The main shaft 6 is provided with a main shaft linkage part 61. The driven plate is sleeved on the main shaft 6 through the driven plate rotation holes 1212. The driven plate can rotate around the main shaft 6, and after the driven plate driving part 1213 contacts and is limited by the main shaft linkage part 61, the driven plate drives the main shaft 6 to rotate. The operating mechanism of this embodiment directly installs the driven plate of the linkage mechanism on the main shaft 6. The driven plate can rotate around the main shaft 6, and after the driven plate driving part 1213 contacts the main shaft linkage part 61, it drives the main shaft 6 to rotate. There is no need for a redundant transmission structure, which has the characteristics of simple and compact structure.

[0094] In particular, when the flipping member 3 drives the first energy storage mechanism 1 to store energy and release energy after passing the equilibrium position, the driven part 1213 of the driven plate of the first energy storage mechanism 1 only contacts and limits contact with the main shaft linkage part 61 when the energy storage spring of the first energy storage mechanism 1 reaches the equilibrium position or after passing the equilibrium position. That is, during the energy storage process before the energy storage spring of the first energy storage mechanism 1 reaches the equilibrium position, the driven plate of the first energy storage mechanism 1 rotates around the main shaft 6, and the driven part 1213 moves in the direction close to the main shaft linkage part 61, and the two do not contact each other. When the flipping component 3 drives the second energy storage mechanism 2 to store energy and release energy after passing the equilibrium position, the driven part 1213 of the driven plate of the second energy storage mechanism 2 only contacts and limits contact with the main shaft linkage part 61 when the energy storage spring of the second energy storage mechanism 2 reaches the equilibrium position or after passing the equilibrium position. That is, during the energy storage process before the energy storage spring of the second energy storage mechanism 2 reaches the equilibrium position, the driven plate of the second energy storage mechanism 2 rotates around the main shaft 6, and the driven part 1213 moves towards the main shaft linkage part 61, without contact limiting between the two. In this way, during the energy storage process of the energy storage mechanism, the main shaft 6 does not move. After the energy storage mechanism releases energy, it drives the main shaft 6 to rotate quickly to switch the power supply. The switching speed of the automatic transfer switch is independent of the speed of the manual operation mechanism and the automatic operation mechanism, which can ensure that the operation mechanism can quickly drive the main shaft 6 to switch the power supply, reduce the burning of the switch contact system by the electric arc, and improve the performance and reliability of the transfer switch.

[0095] Of course, as another inferior embodiment, the driven plates of the first energy storage mechanism 1 and the second energy storage mechanism 2 can also be sleeved on the main shaft 6 and fixedly connected to the main shaft 6, rotating synchronously. However, this solution requires a larger operating force when performing opening and closing operations. As another inferior embodiment, the driven plates of the first energy storage mechanism 1 and the second energy storage mechanism 2 can also be rotatably arranged on both sides of the main shaft 6, driving the main shaft 6 to rotate through the protruding structure on the outer side of the driven plate, or indirectly driving the main shaft 6 to rotate through a transmission mechanism. For example, the transmission mechanism is two incomplete gears driving a connection, or the transmission mechanism is a connecting rod and a sliding groove driving a connection, etc.

[0096] Specifically, such as Figures 10a-11bAs shown, the first driven plate 121 and the second driven plate 221 in this embodiment have similar structures, both having a driven plate rotation hole 1212. A protruding structure is provided within the driven plate rotation hole 1212 as a driven plate driving part 1213. The main shaft 6 has a main shaft linkage part 61 that cooperates with the driven plate driving part 1213. The main shaft 6 has an arc-shaped sidewall for rotating the driven plate rotation hole 1212, and a main shaft clearance notch 62 for avoiding the driven plate driving part 1213. The connection between the spindle clearance notch 62 and the arc sidewall also serves as the spindle linkage part 61. The driven plates of the first energy storage mechanism 1 and the second energy storage mechanism 2 can rotate within the area corresponding to the driven plate driving part 1213 and the spindle clearance notch 62. When the driven plate driving part 1213 rotates to the connection between the spindle clearance notch 62 and the arc sidewall, it contacts and limits the spindle linkage part 61. The rotation of the driven plates of the first energy storage mechanism 1 and the second energy storage mechanism 2 can drive the spindle 6 to rotate.

[0097] The assembly structure of this embodiment is easy to assemble and implement, and is compatible with the installation of the flip-over component 3 and the driven plate. For example... Figure 11a and Figure 11b As shown, the spindle 6 includes a first spindle connecting section 63, a spindle mounting section 64, a second spindle connecting section 65, and a spindle output section 66 arranged sequentially. The cross-section of the spindle mounting section 64 includes alternating arc-shaped sidewalls and planar sidewalls. The arc-shaped sidewalls have the same center and are used for the rotation of the driven plate. The notch in the planar sidewall serves as a spindle clearance notch 62. The connection between the spindle clearance notch 62 and the arc-shaped sidewall is the spindle linkage part 61. In this embodiment, the cross-sections of the first spindle connecting section 63, the spindle mounting section 64, the second spindle connecting section 65, and the spindle output section 66 are all oval, including two oppositely arranged arc-shaped sidewalls and two oppositely arranged planar sidewalls. The two ends of the two arc-shaped sidewalls are respectively connected between the two arc-shaped sidewalls. The corresponding driven plate is also provided with two driven plate driving parts 1213. The first connecting section 63 and the second connecting section 65 of the spindle correspond to the first side plate 103 and the second side plate 104, respectively. The spindle mounting section 64 is located between the first side plate 103 and the second side plate 104 and is used to mount the first driven plate 121, the second driven plate 221, and the flipping component 3. The spindle output section 66 is used to connect with the switch contact system. A baffle mounting groove 67 is also provided on the second connecting section 65 of the spindle for mounting the baffle 54. Figure 12 Obviously, as in other embodiments, the cross-sections of the first connecting segment 63 of the spindle, the second connecting segment 65 of the spindle, and the output segment 66 of the spindle can also be other shapes, such as rectangles, polygons, etc.

[0098] The first driven plate 121 and the second driven plate 221 are rotatably mounted on the main shaft mounting section 64 of the main shaft 6 through their respective driven plate rotation holes 1212. The flipping member 3 is rotatably mounted on the main shaft 6 through a circular flipping member rotation hole 33 and is located between the first driven plate 121 and the second driven plate 221. The flipping member 3 can rotate around the main shaft 6, and the first driven plate 121 and the second driven plate 221 can rotate around the main shaft 6. After the driven plate driving part 1213 of the driven plate rotation hole 1212 contacts the main shaft linkage part 61, it drives the main shaft 6 to rotate.

[0099] The flipping component 3 drives the first connecting rod shaft 123 through the first arc groove 31, causing the first driven plate 121 and the first pulling plate 122 to rotate, so that the first energy storage spring 11 stores energy first. At this time, the driven part 1213 of the driven plate corresponds to the main shaft clearance notch 62 and does not drive the main shaft 6 to rotate. After the first energy storage spring 11 passes the equilibrium position (or when the first energy storage spring 11 is in the equilibrium position), the driven part 1213 of the driven plate 121 contacts and limits the main shaft linkage part 61. The first energy storage spring 11 releases energy and drives the first driven plate 121 to rotate through the first pulling plate 122. The first driven plate 121 drives the main shaft 6 to rotate. The flipping component 3 drives the second connecting rod shaft 223 through the second arc groove 32, causing the second driven plate 221 and the second pulling plate 222 to rotate, so that the second energy storage spring 21 stores energy first. After the second energy storage spring 21 passes the equilibrium position (or when the second energy storage spring 21 is in the equilibrium position), the driven plate driving part 1213 of the second driven plate 221 contacts and limits the main shaft linkage part 61. The second energy storage spring 21 releases energy and drives the second driven plate 221 to rotate through the second pulling plate 222. After the driven plate driving part 1213 contacts and limits the main shaft linkage part 61, the second driven plate 221 drives the main shaft 6 to rotate.

[0100] It should be noted that one or more driven plates 1213 can be provided in the driven plate rotation hole 1212, and the corresponding spindle clearance notch 62 can also be one or more. Furthermore, as another embodiment, the spindle clearance notch 62 is a groove structure opened on the arcuate sidewall of the spindle, with the driven plate 1213 extending into the groove structure, and the sidewalls on both sides of the groove structure serving as the spindle linkage part 61. As another embodiment, the driven plate 1213 is a groove structure within the driven plate rotation hole 1212, and the spindle linkage part 61 is a protruding structure protruding radially from the spindle 6. The protruding structure on the spindle 6 extends into the groove structure of the driven plate rotation hole 1212, allowing the driven plate to rotate around the arcuate sidewall of the spindle 6 within the area corresponding to the groove structure and the protruding structure. When the sidewall of the groove structure contacts the protruding structure of the spindle 6, the driven plate is limited in contact with the spindle 6.

[0101] The operating mechanism of this embodiment is a three-position changeover switch operating mechanism. The flipping component 3 is rotatably configured to rotate to the first position, the middle position, and the second position. The first and second positions are symmetrically arranged on both sides of the middle position. The main shaft 6 can rotate between three positions: the main power supply closed position, the dual-open position, and the backup power supply closed position. When the flipping component 3 is in the middle position, the main shaft 6 is in the dual-open position. When the flipping component is in the first position, the main shaft 6 is in the main power supply closed position. When the flipping component is in the second position, the main shaft 6 is in the backup power supply closed position.

[0102] When the flipper 3 rotates from the middle position to the first position, or from the first position to the middle position, the first linkage mechanism 12 drives the first energy storage spring 11 to store energy and then release energy after passing the balance position (dead point position). The release of energy by the first energy storage spring 11 drives the first linkage mechanism 12 to rotate the main shaft 6 to the corresponding main power supply closed position or double open position. When the flipper 3 rotates from the middle position to the second position, or from the second position to the middle position, the second linkage mechanism 22 drives the second energy storage spring 21 to store energy and then release energy after passing the balance position (dead point position). The release of energy by the second energy storage spring 21 drives the second linkage mechanism 22 to rotate the main shaft 6 to the corresponding backup power supply closed position or double open position.

[0103] It should be noted that, as another embodiment, the operating mechanism of this embodiment can also be used for a two-position switching switch, such as adjusting the position and length of the first arc groove 31 and the second arc groove 32. The flipping member 3 can rotate to the first position and the second position of the flipping member, and the main shaft 6 can rotate between the main power supply closed position and the backup power supply closed position. When the flipping member 3 moves from the second position to the first position, it drives the first linkage mechanism 12 to drive the first energy storage spring 11 to store energy and then release energy after passing the balance position (dead point position). The release of energy by the first energy storage spring 11 drives the first linkage mechanism 12 to drive the main shaft 6 to rotate to the corresponding main power supply closed position. When the flipping member 3 moves from the first position to the second position, it drives the second linkage mechanism 22 to drive the second energy storage spring 21 to store energy and then release energy after passing the balance position (dead point position). The release of energy by the second energy storage spring 21 drives the second linkage mechanism 22 to drive the main shaft 6 to rotate to the corresponding backup power supply closed position or the dual-position.

[0104] The specific operation process of the energy storage mechanism in this embodiment is as follows: Figure 2b , Figure 2d , Figure 3a , Figure 3b , Figure 4a , Figure 4b , Figure 4c , Figure 5a and Figure 5b As shown, when the flipping component 3 rotates from the middle position to the first position, or from the first position to the middle position, the first connecting rod shaft 123 is basically located at one end sidewall of the first arc groove 31. The flipping component 3 drives the first connecting rod shaft 123 through the end sidewall of the first arc groove 31, thereby driving the first driven plate 121 and the first pulling plate 122 to move. The first pulling plate 122 is pulled by force to store energy in the first energy storage spring 11. When the first energy storage spring 11 is in the equilibrium position, the energy storage is completed. The equilibrium position is as follows: Figure 3b and Figure 5b As shown, the rotation axes of the first energy storage spring 11 and the first driven plate 121, and the first connecting rod shaft 123 are in the same straight line and are in force balance. The forces on the first energy storage spring 11 and the first connecting rod shaft 123 cancel each other out, and the flipping part 3 continues to rotate counterclockwise under force (as shown). Figure 3b ) or the flipping part 3 continues to rotate clockwise under force (such as Figure 5b After the first driven plate 121 and the first pulling plate 122 drive the first energy storage spring 11 slightly past the balance position, the flipping part 3 reaches the first position or the middle position of the flipping part. The driven part 1213 of the driven plate contacts and limits the contact with the main shaft linkage part 61. The energy of the first energy storage spring 11 is released. The first energy storage spring 11 pulls the first pulling plate 122, so that the first pulling plate 122 drives the first driven plate 121 to rotate through the first connecting rod shaft 123. The first driven plate 121 drives the main shaft 6 to rotate to the corresponding main power supply closed position or double open position through the driven part 1213, realizing the state switching of the automatic transfer switch. After the first energy storage spring 11 releases energy, the first connecting rod shaft 123 slides from one end of the side wall of the first arc groove 31 to the other end of the first arc groove 31, and the flipping part 3 does not rotate. During this process, the second linkage shaft 223 of the second linkage mechanism 22 slides in the second arcuate groove 32 of the flipping member 3, sliding from one end sidewall of the second arcuate groove 32 to the other end sidewall, and the second linkage mechanism 22 does not move. The driven part 1213 of the first driven plate 121 and the main shaft linkage part 61 of the main shaft 6 can contact each other at the equilibrium position or after the first energy storage spring 11 releases energy.

[0105] like Figure 2b , Figure 6a , Figure 6b , Figure 6b , Figure 7a and Figure 8aAs shown, when the flipping component 3 rotates from the middle position to the second position, or from the second position to the middle position, the flipping component 3 drives the second linkage mechanism 22 to move via the second arc groove 32 and the second linkage shaft 223. The movement process is similar to that of the first linkage mechanism 12 and the first energy storage spring 11, and will not be described again. During this process, the first linkage shaft 123 of the first linkage mechanism 12 slides in the first arc groove 31 of the flipping component 3, and the first linkage mechanism 12 does not move.

[0106] Preferably, the operating mechanism is provided with a first link limiting part 1025 and a second link limiting part, which are respectively used to limit the rotational position of the driven plate after the first energy storage mechanism 1 and the second energy storage mechanism 2 release energy, so as to accurately and reliably limit the rotational position of the main shaft 6. In this embodiment, the first link limiting part 1025 and the second link limiting part are arranged on the bracket 102, such as... Figure 18 As shown, in this embodiment, two first link limiting parts 1025 are provided on the first side plate 103, which are used to limit the rotation position of the first driven plate 121 after the first energy storage mechanism 1 releases energy when the flipping member 3 rotates to the first position of the flipping member and the middle position of the flipping member, respectively; correspondingly, two second link limiting parts are also provided on the second side plate 104, which are used to limit the rotation position of the second driven plate 221 after the second energy storage mechanism 2 releases energy when the flipping member 3 rotates to the second position of the flipping member and the middle position of the flipping member, respectively. Of course, as another embodiment, the first link limiting parts 1025 and the second link limiting parts may not be provided, and the rotation position of the first driven plate 121 and the second driven plate 221 may be limited only by the side walls at both ends of the first arc groove 31 and the second arc groove 32 of the flipping member 3.

[0107] like Figure 10a , 10bAs shown, in a preferred embodiment of the first linkage mechanism 12 and the second linkage mechanism 22, the two have the same structure, each including a driven plate and a pulling plate. The structure of the driven plate and the pulling plate is described below using the driven plate and the pulling plate of the first linkage mechanism 12, namely the first driven plate 121 and the first pulling plate 122, as an example. The first driven plate 121 includes a driven plate rotating part, with a driven plate rotating hole 1212 in the middle of the driven plate rotating part. A driven plate connecting part protrudes radially outward from the driven plate rotating part. The driven plate connecting part is hinged to one end of the first pulling plate 122 via a first connecting rod shaft 123. A protruding structure is provided in the driven plate rotating hole 1212 as a driven plate driving part 1213. A driven plate limiting part 1216 also protrudes radially outward from the driven plate rotating part, which is used to cooperate with the first connecting rod limiting part 1025 and the second connecting rod limiting part on the bracket 102. The driven plate limiting part 1216 and the driven plate connecting part are respectively located on both sides of the driven plate rotating part. The first pulling plate 122 is a plate-shaped structure. The first end of the first pulling plate 122 is connected to the first energy storage spring 11, and the second end is connected to the first driven plate 121. A bending part is provided between the first end and the second end of the first pulling plate 122. In this embodiment, the bending portion makes the first pulling plate 122 into a V-shaped or U-shaped structure. This structure helps to avoid the main shaft 5 during the rotation of the first linkage mechanism 12, and reduces the rotation distance between the first driven plate 121 and the first pulling plate 122, as well as the space occupied. In other embodiments, the first pulling plate 122 may also be a straight structure or other shapes, or have multiple bending portions.

[0108] like Figure 2b As shown, the first energy storage mechanism 1 and the second energy storage mechanism 2 are arranged symmetrically along the axis of symmetry, which is as follows: Figure 2b A vertical line passing through the rotation axis of the flipping member 3 or the main shaft 6, that is, a vertical line passing through the rotation axis of the first driven plate 121, is drawn in the vertical direction. The axis of symmetry is perpendicular to the axial direction of the main shaft 6 and passes through the rotation axis of the flipping member 3. The first energy storage spring 11 and the second energy storage spring 21 are respectively located on both sides of this axis of symmetry. The two ends of the first pulling plate 122 are also respectively located on both sides of this axis of symmetry. The two ends of the second pulling plate 222 are also respectively located on both sides of this axis of symmetry. The first energy storage spring fixing shaft 1023, the first energy storage spring 11, the first end of the first pulling plate 122, and the second end of the second pulling plate 222 are located on one side of the axis of symmetry. Figure 2b (Left side), the second energy storage spring fixing shaft 1024, the first end of the second energy storage spring 21 and the second pull plate 222, and the second end of the first pull plate 122 are located on the other side of the axis of symmetry. Figure 2b (Right side)

[0109] Preferably, the driven plates of the first linkage mechanism 12 and the second linkage mechanism 22 include two driven plates 1214 arranged at relative intervals. A pulling plate can rotate between the two driven plates 1214. The two driven plates 1214 are connected by a plurality of driven plate fixing shafts. The second end of the pulling plate of the first linkage mechanism 12 and the second linkage mechanism 22 extends between the two driven plates 1214. A connecting shaft passes through the two driven plates 1214 and the second end of the pulling plate, hinged to the driven plate and the pulling plate. Both the driven plate and the pulling plate can rotate around the connecting shaft. Preferably, a pulling plate limiting shaft 1215 is also provided between the two driven plates 1214 to limit the rotation angle of the pulling plate. Preferably, a limiting plate driving part 1211 is also provided between the two driven plates 1214. The pulling plate limiting shaft 1215 and the limiting plate driving part 1211 are also the driven plate fixing shafts between the two driven plates 1214.

[0110] Another improvement of this application is that the operating mechanism further includes a toggle 4, which can be used as part of a manual operating mechanism, and / or as part of an automatic operating mechanism, and / or to cooperate in locking the positions of the flipper 3 and the main shaft 6.

[0111] The following describes the cooperative structure between the toggle member 4 and the flipping member 3, using the toggle member 4 as a manual operating mechanism. In this embodiment, the manual operating mechanism includes the toggle member 4, which is drivenly connected to the flipping member 3, and is used to drive the flipping member 3 to rotate to the first position, the middle position, and the second position. Figure 9a , Figure 9b and Figure 13 As shown, in this embodiment, the actuating member 4 is rotatably configured, the flipping member 3 is provided with a first linkage part 34, and the actuating member 4 is provided with a second linkage part 41. The actuating member 4 is linked with the flipping member 3 through the second linkage part 41. The actuating member 4 can rotate to a first position, a middle position, and a second position. The first and second positions are symmetrically arranged on both sides of the middle position. When the actuating member 4 rotates to the first, middle, and second positions, it drives the flipping member 3 to rotate to the corresponding positions, and the flipping member 3 drives the first energy storage mechanism 1 or the second energy storage mechanism 2 to rotate the main shaft 6. Preferably, when the flipping member 3 rotates to the first, middle, and second positions, it drives the actuating member 4 to rotate to the corresponding positions, so that the actuating member 4 can indicate the state of the flipping member 3. Obviously, as another embodiment, the rotation of the toggle member 4 can drive the rotation of the flipping member 3 in one direction, while the rotation of the flipping member 3 can not drive the toggle member 4, which is also within the scope of protection of this application.

[0112] In this embodiment, as Figure 2c , Figure 9a , Figure 9b and Figure 13 As shown, the first linkage part 34 and the second linkage part 41 are gears, and the flipping member 3 and the actuating member 4 are linked by gear meshing. Obviously, as other embodiments, the flipping member 3 and the actuating member 4 can also be driven and connected by means of hinge, drive rod and drive groove cooperation, etc. For example, a drive groove is provided on the flipping member 3, and the actuating member 4 can be provided with a drive rod that cooperates with it. The drive rod is inserted into the drive groove and drives the flipping member 3 to rotate to both sides by pushing the two side walls of the drive groove; in addition, the actuating member 4 can also indirectly drive the flipping member 3 through a transmission mechanism such as a connecting rod or lever; all of these are within the protection scope of this application.

[0113] like Figure 13 As shown, the actuating element 4 is provided with a driving part 45 for manual operation, used to drive the actuating element 4 to rotate. In this embodiment, the driving part 45 is a hole-like structure, and the actuating element 4 is driven to rotate by inserting a driving rod. Obviously, as another embodiment, the driving part 45 can also be a protruding handle, with the handle extending out of the housing of the operating mechanism, and the actuating element 4 can be driven to rotate by directly operating the handle. In addition, the manual operating mechanism can also include other transmission mechanisms, which can indirectly drive the actuating element 4 to rotate. If the actuating element 4 is driven by an electric mechanism, the actuating element 4 can be used as part of the automatic operating mechanism and is not used in the manual operating mechanism. For example, the automatic operating mechanism includes a first electromagnetic mechanism 7 and a second electromagnetic mechanism 8. The first electromagnetic mechanism 7 and the second electromagnetic mechanism 8 each include an electromagnetic component and a moving rod 782 connected to the electromagnetic component. When the electromagnetic component is energized, it drives the moving rod 782 to drive the actuating element 4 to rotate. Alternatively, the automatic operating mechanism includes a motor and a gear set connected to the motor. The motor drives the actuating element 4 to rotate through the gear set. The gear set and the actuating element 4 can be connected by an incomplete gear transmission.

[0114] Preferably, the actuating element 4 is used to drive the indicating mechanism to indicate the state of the operating mechanism. For example, the actuating element 4 has an indicating part for indicating the state of the operating mechanism. In an optional embodiment, the actuating element 4 has an indicating rod (not shown in the figure) extending out of the housing of the operating mechanism as the indicating part, and the housing of the operating mechanism has an indicating mark. When the actuating element 4 is rotated to the first position, the middle position, and the second position, the indicating rod corresponds to different indicating marks to indicate the state of the operating mechanism; the indicating mechanism includes the indicating part of the actuating element 4 and the indicating mark. Preferably, the handle also serves as the indicating rod. Two or three indicating marks can be provided on the housing of the operating mechanism. In another optional embodiment, the actuating element 4 has multiple indicating marks (not shown in the figure) as indicating parts, and the housing of the operating mechanism has an indicating window. When the actuating element 4 is rotated to the first position, the middle position, and the second position, different indicating marks correspond to the indicating window; the indicating mechanism includes the indicating part of the actuating element 4 and the indicating window. In another embodiment, the indicating mechanism includes an indicator element, and the toggle element 4 drives the indicator element to move to indicate the state of the operating mechanism.

[0115] It should be noted that the manual operating mechanism may not use the rotating toggle 4, but may use other methods such as a sliding push rod to drive and cooperate with the flipping component 3.

[0116] Another improvement of this application is the provision of a spindle locking mechanism 5, which is used to lock the spindle 6 in the main power-on position or the backup power-on position. When the flipping member 3 rotates to the first position of the flipping member, the spindle locking mechanism 5 is driven to lock the spindle 6, so that the spindle 6 cannot rotate to the double-split position. When the flipping member 3 rotates to the middle position of the flipping member, the spindle locking mechanism 5 is driven to release the lock on the spindle 6. When it rotates to the second position of the flipping member, the spindle locking mechanism 5 is driven to lock the spindle 6, so that the spindle 6 cannot rotate to the double-split position. This prevents other mechanisms outside the operating mechanism from driving the spindle 6 to flip, thereby improving reliability and safety.

[0117] like Figure 2d , 11a 11b Figure 12 as well as Figure 15As shown, the spindle locking mechanism 5 in this embodiment includes a first lever 51 and a second lever 52. The first lever 51 is provided with a first lever locking part 512, and the second lever 52 is provided with a second lever locking part 522. The spindle 6 is provided with a first locking part 541 and a second locking part 542. When the flipping member 3 moves to the first position of the flipping member, it avoids the first lever 51, so that the first elastic member 53 drives the first lever 51 to move the first lever locking part 512 towards the spindle 6. When the spindle 6 rotates to the main power on position, the first locking part 541 of the spindle 6 locks with the first lever locking part 512, so that the spindle 6 cannot rotate to the double-split position, locking the spindle 6 in the main power on position. When the flipping member 3 moves to the second position of the flipping member, it avoids the second lever 52, so that the second elastic member drives the second lever 52 to move the first lever locking part 541 and the second locking part 542 towards the spindle 6. The second lever locking part 522 moves towards the main shaft 6. When the main shaft 6 rotates to the backup power on position, the second locking part 542 of the main shaft 6 locks with the second lever locking part 522, preventing the main shaft 6 from rotating to the split position and locking the main shaft 6 in the backup power on position. When the flipping part 3 rotates from the first position to the middle position, it drives the first lever 51 to overcome the force of the first elastic member 53 and move the first lever locking part 512 away from the main shaft 6, releasing the locking engagement with the first locking part 541 of the main shaft 6. When the flipping part 3 rotates from the second position to the middle position, it drives the second lever 52 to overcome the force of the second elastic member and move the second lever locking part 522 away from the main shaft 6, releasing the locking engagement with the second locking part 542 of the main shaft 6.

[0118] like Figure 2d , Figure 4c , Figure 5c , Figure 7b as well as Figure 8b In a preferred embodiment shown, the first elastic element 53 also serves as the second elastic element, that is, the first elastic element 53 and the second elastic element are the same elastic element. The first elastic element 53 is connected between the first lever 51 and the second lever 52. Only one first elastic element 53 needs to be provided, which simplifies the structure.

[0119] In this embodiment, the spindle locking mechanism 5 further includes a baffle 54, which is fixedly mounted on the spindle 6. A first locking part 541 and a second locking part 542 are mounted on the baffle 54. (Reference) Figure 14 In this embodiment, the baffle 54 has a baffle mounting hole 543 in the middle, and the baffle 54 is fitted onto the main shaft 6 through the baffle mounting hole 543 and rotates integrally with the main shaft 6. In other embodiments, the baffle 54 can also be integrally formed with the main shaft 6, that is, the first locking part 541 and the second locking part 542 are directly provided on the main shaft 6.

[0120] In this embodiment, the flipping component 3 drives the main shaft locking mechanism 5 via the actuating component 4. When the flipping component 3 rotates to the first position, the middle position, and the second position, the actuating component 4 rotates to the corresponding positions. When the actuating component 4 rotates to the first and second positions, it drives the main shaft locking mechanism 5 to lock the main shaft 6, preventing it from rotating to the split position. When the actuating component 4 rotates to the middle position, it drives the main shaft locking mechanism 5 to release the lock on the main shaft 6. Alternatively, the flipping component 3 can directly drive the first lever 51 and the second lever 52, or drive them through other transmission structures.

[0121] Specifically, such as Figure 2d , Figure 4c , Figure 5c , Figure 7b as well as Figure 8b As shown, the spindle locking mechanism 5 in this embodiment includes a first lever 51, a second lever 52, a first elastic element 53, and a baffle 54. The first lever 51 and the second lever 52 are arranged side by side with intervals. The first end of the first lever 51 is rotatably disposed, and the second end is provided with a first lever groove 511. The first lever groove 511 is fitted onto the first lever limiting shaft 513 of the bracket 102 to limit the rotation angle of the first lever 51. The first end of the second lever 52 is rotatably disposed, and the second end is provided with a second lever groove 521. The second lever groove 521 is fitted onto the second lever limiting shaft 523 of the bracket 102 to limit the rotation angle of the second lever 52. The first elastic element 53 is connected between the second end of the first lever 51 and the second end of the second lever 52, and is used to drive the second end of the first lever 51 and the second lever 52. The two ends are close to each other. The actuating member 4 is provided with a third actuating part 44, which is located between the second end of the first lever 51 and the second end of the second lever 52. The first lever 51 is provided with a first lever locking part 512 on its side, and the second lever 52 is provided with a second lever locking part 522 on its side. They are respectively located on both sides of the main shaft 6. The baffle 54 is fixedly installed on the main shaft 6 and rotates with the main shaft 6. The baffle 54 is located between the first lever 51 and the second lever 52. The side of the baffle 54 is provided with a first locking part 541 and a second locking part 542. The first locking part 541 cooperates with the first lever locking part 512 to lock the main shaft 6 in the main power on position. The second locking part 542 cooperates with the second lever locking part 522 to lock the main shaft 6 in the backup power on position.

[0122] like Figure 2dAs shown, in the split state, the actuating member 4 is located in the middle position of the actuating member, the flipping member 3 is located in the middle position of the flipping member, the main shaft 6 is located in the split position, and the third actuating part 44 of the actuating member 4 is also located in the middle position. Due to the action of the first elastic member 53, the second end of the first lever 51 and the second end of the second lever 52 simultaneously contact the third actuating part 44 of the actuating member 4. The first lever locking part 512 of the first lever 51 and the second lever locking part 522 of the second lever 52 are respectively misaligned with the corresponding first locking part 541 and second locking part 542, corresponding to the arc-shaped side 544 of the baffle 54, and the main shaft 6 is not locked.

[0123] like Figure 2d and Figure 4c As shown, when the actuating member 4 rotates from the middle position to the first position, the flipping member 3 simultaneously rotates from the middle position to the first position and drives the first energy storage mechanism 1 to store energy. The third actuating part 44 of the actuating member 4 drives the second end of the second lever 52, causing the second lever locking part 522 to move away from the main shaft 6 and leave the baffle 54. The third actuating part 44 of the actuating member 4 avoids the second end of the first lever 51. Under the action of the first elastic member 53, the first lever 51 drives the first lever locking part 512 to move closer to the main shaft 6, applying a greater force. Afterwards, the flipping member 3 drives the first energy storage mechanism 1 to release energy after passing the equilibrium position. The main shaft 6 also rotates from the dual-position position to the main power supply closed position under the energy release drive of the first energy storage mechanism 1 (from the... Figures 2d to 4c During the process (counterclockwise rotation), the first locking part 541 of the main shaft 6 locks with the first lever locking part 512, preventing the main shaft 6 from rotating to the split position (cannot rotate towards the split position). Figure 4c Rotate clockwise to lock spindle 6 in the main power-on position. (Continue to refer to...) Figure 4c When the actuating member 4 rotates from the first position to the middle position, the flipping member 3 also rotates from the first position to the middle position, driving the first energy storage mechanism 1 to store energy. The third actuating part 44 of the actuating member 4 drives the first lever 51 to overcome the force of the first elastic member 53, causing the first lever locking part 512 to move away from the main shaft 6, so that the first lever locking part 512 leaves the first locking part 541 of the baffle 54, releasing the lock on the main shaft 6. Afterwards, the flipping member 3 drives the first energy storage mechanism 1 to release energy after passing the equilibrium position, and the main shaft 6 rotates to the double-split position under the energy release drive of the first energy storage mechanism 1. Among them, the main shaft locking mechanism 5 in the double-split position is in Figure 2d As shown in the image.

[0124] like Figure 2d and Figure 7bAs shown, when the actuating member 4 rotates from the middle position to the second position, the flipping member 3 rotates from the middle position to the second position and drives the second energy storage mechanism 2 to store energy first. The third actuating part 44 of the actuating member 4 drives the second end of the first lever 51 to move the first lever locking part 512 away from the main shaft 6 and away from the baffle 54. The third actuating part 44 of the actuating member 4 avoids the second end of the second lever 52. Under the action of the first elastic member 53, the second lever 52 drives the second lever locking part 522 to move closer to the main shaft 6 and also applies a greater force. Afterwards, the flipping member 3 drives the second energy storage mechanism 2 to release energy after passing the equilibrium position. The release of energy by the second energy storage mechanism 2 drives the main shaft 6 to rotate from the double-open position to the backup power supply closed position (from the... Figures 2d to 7b During the process (clockwise rotation), the second locking part 542 of the main shaft 6 locks with the second lever locking part 522, preventing the main shaft 6 from rotating to the split position (cannot rotate towards the split position). Figure 7b Rotate counterclockwise to lock the main shaft 6 in the backup power supply closed position.

[0125] When the actuating member 4 rotates from the second position to the middle position, the flipping member 3 also rotates from the second position to the middle position and drives the second energy mechanism 2 to store energy. The third actuating part 44 of the actuating member 4 drives the second lever 52 to overcome the force of the first elastic member 53 and drive the second lever locking part 522 to move away from the main shaft 6, so that the second lever locking part 522 leaves the second locking part 542 of the baffle 54 and releases the lock on the main shaft 6. After that, the flipping member 3 drives the second energy storage mechanism 2 to release energy after passing the balance position, and the main shaft 6 rotates to the double split position under the energy release drive of the second energy storage mechanism 2.

[0126] like Figure 12 As shown, this is one embodiment of the baffle 54. The baffle 54 has a circular structure with an arc-shaped side 544, and a locking groove is formed on the arc-shaped side 544. The two side walls of the locking groove serve as the first locking part 541 and the second locking part 542, respectively. A baffle mounting hole 543 is provided in the middle of the baffle 54, and the baffle 54 is mounted on the main shaft 6 through the baffle mounting hole 543 and rotates integrally with the main shaft 6. In other embodiments, the baffle 54 can also be integrally formed with the main shaft 6.

[0127] like Figure 15 As shown, this is one embodiment of the first lever 51. The second lever 52 has the same structure as the first lever 51. The first lever 51 and the second lever 52 are plate-shaped structures. Each of them has a rotating hole at its first end, allowing it to be rotatably mounted on the bracket 102. Each of them has an arc-shaped hole at its second end, which serves as the first lever groove 511 and the second lever groove 521, respectively.

[0128] The opposing sides of the first lever 51 and the second lever 52, from the first end to the second end, are sequentially provided with a first arc-shaped surface 551, a locking protrusion 552, and a second arc-shaped surface 553. The locking protrusions 552 on the first lever 51 and the second lever 52 respectively serve as the first lever locking part 512 and the second lever locking part 522. Preferably, the side of the locking protrusion 552 near the first arc-shaped surface 551 is arc-shaped and is part of the first arc-shaped surface 551. The arc-shaped side 544 of the baffle 54 can cooperate with the first arc-shaped surface 551 to facilitate lifting the first lever 51 or the second lever 52 so that the first locking part 541 or the second locking part 542 locks with the corresponding first lever locking part 512 and the second lever locking part 522. The side of the locking protrusion 552 near the second arc-shaped surface 553 is flat and is used to lock and cooperate with the first locking part 541 of the spindle 6. Preferably, the opposite sides of the first lever 51 and the second lever 52 are each provided with a second protrusion 554 at the second end, which is used to cooperate with the third actuating part 44 of the actuating member 4.

[0129] Another improvement in this application lies in the drive-coupling structure between the automatic operating mechanism and the tilting component 3. For example... Figure 2a , Figure 2c As shown, the automatic operation mechanism of this embodiment includes a first electromagnetic mechanism 7 and a second electromagnetic mechanism 8. The first electromagnetic mechanism 7 is used to drive the flipping member 3 to rotate from the second position of the flipping member to the middle position of the flipping member, and from the middle position of the flipping member to the first position of the flipping member. The second electromagnetic mechanism 8 is used to drive the flipping member 3 to rotate from the first position of the flipping member to the middle position of the flipping member, and from the middle position of the flipping member to the second position of the flipping member. The flipping member 3 drives the first energy storage mechanism 1 or the second energy storage mechanism 2 to drive the main shaft 6 to rotate.

[0130] like Figure 2c and Figure 16 As shown, the first electromagnetic mechanism 7 and the second electromagnetic mechanism 8 each include an electromagnetic component and a movable rod 782 connected to the electromagnetic component. The movable rod 782 is provided with a movable rod driving part 7822. When the electromagnetic component is energized, it drives the movable rod 782 to move and drive the flipping part 3 to rotate. When the electromagnetic component is de-energized, the movable rod 782 returns to its original position. The electromagnetic components of the first electromagnetic mechanism 7 and the second electromagnetic mechanism 8 are the first electromagnetic component 71 and the second electromagnetic component 81, respectively. The two movable rods 782 of the first electromagnetic mechanism 7 and the second electromagnetic mechanism 8 are the first movable rod 72 and the second movable rod 82, respectively. The two movable rod driving parts 7822 of the first movable rod 72 and the second movable rod 82 are the first movable rod driving part 722 and the second movable rod driving part 822, respectively.

[0131] In this embodiment, the first moving rod drive unit 722 and the second moving rod drive unit 822 are hook structures used to pull the flipping member 3 to rotate. When the first electromagnetic component 71 is energized, it pulls the flipping member 3 through the first moving rod 72; when the first electromagnetic component 71 is de-energized, it drives the first moving rod 72 to reset. When the second electromagnetic component 81 is energized, it pulls the flipping member 3 through the second moving rod 82; when the second electromagnetic component 81 is de-energized, it drives the second moving rod 82 to reset. The first electromagnetic component 71 and the second electromagnetic component 81 typically include a moving iron core, a stationary iron core, and a reaction spring located between the moving iron core and the stationary iron core, which is prior art in the art. The first moving rod 72 and the second moving rod 82 are respectively connected to the moving iron core of the first electromagnetic component 71 and the second electromagnetic component 81.

[0132] like Figure 2c and Figure 9a , Figure 11b As shown, the flipping component 3 is provided with a third linkage part 35 and a fourth linkage part 36 spaced apart. The first electromagnetic mechanism 7 and the second electromagnetic mechanism 8 drive the flipping component 3 to rotate through the third linkage part 35 and the fourth linkage part 36. In this embodiment, the third linkage part 35 and the fourth linkage part 36 are convex shafts on the flipping component 3. Figure 2c As shown, when the flipping component 3 is in the middle position, the third linkage part 35 and the fourth linkage part 36 are located between the two moving rod driving parts 7822 of the first moving rod 72 and the second moving rod 82. When the first electromagnetic mechanism 7 is energized, it can drive the first moving rod 72 to move. The first moving rod driving part 722 drives the third linkage part 35 to rotate the flipping component 3 from the middle position to the first position. Alternatively, when the second electromagnetic mechanism 8 is energized, it can drive the second moving rod 82 to move. The second moving rod driving part 822 drives the fourth linkage part 36 to rotate the flipping component 3 from the middle position to the second position. See also... Figure 2cThe first electromagnetic component 71 and the second electromagnetic component 81 are symmetrically arranged on both sides of the flipping component 3. In the figure, the first electromagnetic component 71 is located on the right side and the second electromagnetic component 81 is located on the left side. When the flipping component 3 is located in the middle position of the flipping component, the first moving rod drive part 722 at the end of the first moving rod 72 connected to the first electromagnetic component 71 extends to the left side of the third linkage part 35 and the fourth linkage part 36. The second moving rod drive part 822 at the end of the second moving rod 82 connected to the second electromagnetic component 81 extends to the right side of the third linkage part 35 and the fourth linkage part 36. The first moving rod drive part 722 is close to the third linkage part 35 and has a gap with the third linkage part 35. The second moving rod drive part 822 is close to the fourth linkage part 36 and has a gap with the fourth linkage part 36. At this time, the first electromagnetic component 71 can pull the third linkage 35 through the first moving rod drive part 722 to drive the flipping part 3 to rotate counterclockwise to the first position of the flipping part. The fourth linkage part 36 then uses the gap between itself and the second moving rod drive part 822 to rotate out of the space between the first moving rod drive part 722 and the second moving rod drive part 822 with the flipping part 3 (e.g. Figure 4a (As shown), then the first electromagnetic component 71 is de-energized and the first moving rod 72 is reset; the second electromagnetic component 81 can also pull the fourth linkage part 36 through the second moving rod drive part 822, driving the flipping part 3 to rotate clockwise to the second position of the flipping part, and the third linkage part 35 uses the gap between itself and the first moving rod drive part 722 to rotate out of the space between the first moving rod drive part 722 and the second moving rod drive part 822 with the flipping part 3 (as shown). Figure 6b (As shown), then the second electromagnetic component 81 is de-energized and the second moving rod 82 is reset.

[0133] like Figure 4a , Figure 4b As shown, when the flipping component 3 is in the first position, the third linkage part 35 is located between the two moving rod drive parts 7822, and the fourth linkage part 36 rotates out between the two moving rod drive parts 7822. When the second electromagnetic mechanism 8 is energized, it can drive the second moving rod 82 to move. The second moving rod drive part 822 drives the third linkage part 35 to rotate the flipping component 3 from the first position to the middle position. (Reference) Figure 4a , Figure 4b When the flipping component 3 is in the first position, the second moving rod drive part 822 at the end of the second moving rod 82 approaches the third linkage part 35, and the fourth linkage part 36 has rotated out from between the first moving rod drive part 722 and the second moving rod drive part 822. At this time, the second electromagnetic component 81 can pull the third linkage part 35 through the second moving rod drive part 822, driving the flipping component 3 to rotate clockwise to the middle position of the flipping component, restoring it to the first position. Figure 2c The state shown; however, the first moving lever drive unit 722 is far from the third linkage unit 35, so even if it is moved, it cannot pull the third linkage unit 35 again.

[0134] Similarly, such as Figure 7a As shown, when the flipping component 3 is in the second position of the flipping component, the fourth linkage part 36 is located between the two moving rod drive parts 7822, and the third linkage part 35 rotates out between the two moving rod drive parts 7822. When the first electromagnetic mechanism 7 is energized, it can drive the first moving rod 72 to move. The first moving rod drive part 722 drives the fourth linkage part 36 to rotate the flipping component 3 from the second position of the flipping component to the middle position of the flipping component. (Reference) Figure 7a When the flipping component 3 is in the second position, the first moving rod drive part 722 at the end of the first moving rod 72 approaches the fourth linkage part 36, and the third linkage part 35 has rotated out from between the first moving rod drive part 722 and the second moving rod drive part 822. At this time, the first electromagnetic component 71 can pull the fourth linkage part 36 through the first moving rod drive part 722, driving the flipping component 3 to rotate counterclockwise to the middle position of the flipping component, restoring it to the original position. Figure 2c The state shown; however, the second moving lever drive unit 822 is far from the fourth linkage unit 36, so even if it is moved, it cannot pull the fourth linkage unit 36 ​​again.

[0135] In this embodiment, the automatic operating mechanism employs a first electromagnetic mechanism 7 and a second electromagnetic mechanism 8, which provides faster operation compared to a motor and improves the switching speed of the changeover switch. The first electromagnetic mechanism 7 can realize the main power supply closing state of the operating mechanism, as well as the switching of the operating mechanism from the backup power supply closing state to the dual-open state. The second electromagnetic mechanism 8 can realize the backup power supply closing state of the operating mechanism, as well as the switching of the operating mechanism from the main power supply closing state to the dual-open state. The first electromagnetic mechanism 7 and the second electromagnetic mechanism 8 are not directly connected to the flipping member 3, and will not affect other rotational relationships of the flipping member 3. The first electromagnetic mechanism 7 and the second electromagnetic mechanism 8 achieve three-position switching through cooperation with the third linkage part 35 and the fourth linkage part 36 of the flipping member 3. The cooperative structure is ingenious and compact, with high reliability.

[0136] It should be noted that the first electromagnetic mechanism 7 and the second electromagnetic mechanism 8 can also drive the rotating member 3 to rotate by pushing rather than pulling. As another embodiment, the automatic operating mechanism may not use the electromagnetic mechanism of this embodiment, and may also use other methods such as motors or cylinders to directly or indirectly drive the rotating member 3 to rotate.

[0137] like Figure 2c , Figure 16As shown, the electromagnetic components of the first electromagnetic mechanism 7 and the second electromagnetic mechanism 8 both include a moving iron core and a movable rod mounting plate 783 fixedly connected to the moving iron core. The movable rod 782 is rotatably mounted on the movable rod mounting plate 783. The movable rod spring 784 is connected to the movable rod 782. The movable rod spring 784 drives the movable rod 782 to rotate to a horizontal position and is limited and fixed to the movable rod mounting plate 783. When the first electromagnetic mechanism 7 and the second electromagnetic mechanism 8 are de-energized and the movable rod 782 is reset, the third linkage part 35 or the fourth linkage part 36 located on the reset path of the movable rod acts on the movable rod 782, causing the movable rod 782 to rotate against the force of the movable rod spring 784 to avoid the third linkage part 35 or the fourth linkage part 36. When the electromagnetic component is energized, the moving iron core pulls the flipping component 3 to rotate via the moving rod 782. After the first electromagnetic component 71 is de-energized, the moving iron core resets. The third linkage part 35 or the fourth linkage part 36 acts on the inclined surface 7824 of the hook part outside the moving rod drive part 7822 of the moving rod 782, causing the moving rod 782 to rotate against the force of the moving rod spring 784 to avoid the third linkage part 35 or the fourth linkage part 36. It should be noted that the moving rod mounting plate 783 can be integrally set with the moving iron core, or it can be set separately and then fixedly connected.

[0138] like Figure 16 As shown, one end of the moving rod 782 has a mounting hole, serving as a moving rod mounting part 7821, which is hinged to the moving rod mounting plate 783 via a mounting shaft. The other end of the moving rod 782 is a hook structure, which serves as a moving rod driving part 7822 for cooperating with the flipping part 3. The electromagnetic components of the first electromagnetic mechanism 7 and the second electromagnetic mechanism 8 both drive their respective moving rods 782 to pull the flipping part 3 to rotate through the hook structure. The inner side of the hook structure is used to pull the flipping part 3 to rotate, and the outer side of the hook structure is an inclined surface serving as the hook part inclined surface 7824. A moving rod limiting part 7823 is also provided on the moving rod 782. The moving rod limiting part 7823 and the moving rod driving part 7822 are located on both sides of the moving rod mounting part 7821, respectively. One end of the moving rod spring 784 is connected to the moving rod spring mounting hole 7825 on the lower side of the moving rod mounting part 7821, and the other end is connected to the bracket 102. In this embodiment, the moving rod spring 784 is a tension spring, but it can obviously also be a torsion spring or other elastic element.

[0139] refer to Figure 2cIn this embodiment, both the first electromagnetic mechanism 7 and the second electromagnetic mechanism 8 have externally mounted reaction springs 785. One end of the reaction spring 785 is connected to the moving rod mounting plate 783, and the other end is connected to the bracket 102. These reaction springs are used to drive the moving iron core to reset. When the electromagnetic components of the first electromagnetic mechanism 7 and the second electromagnetic mechanism 8 are energized, the moving iron core overcomes the force of the reaction spring 785 and pulls the flipping member 3 to rotate via the moving rod 782. After the electromagnetic components are de-energized, the reaction spring 785 drives the moving iron core to reset. An independent auxiliary bracket 105 can be installed inside the bracket 102 to mount the moving rod spring 784 and the reaction spring 785 of the first electromagnetic mechanism 7 and the second electromagnetic mechanism 8. Alternatively, a corresponding mounting structure can be installed on the first side plate 103 or the second side plate 104 of the bracket 102. It should be noted that, in other embodiments, the reaction spring can also be located inside the electromagnetic component, between the moving iron core and the stationary iron core, or both inside and outside the electromagnetic component can be equipped with reaction springs.

[0140] like Figure 16 As shown, the movable rod mounting plate 783 includes a vertically arranged first movable rod mounting plate 7831 and a second movable rod mounting plate 7832. The second movable rod mounting plate 7832 is fixedly connected to the moving iron core. The movable rod 782 is rotatably mounted on the first movable rod mounting plate 7831. The movable rod spring 784 drives the movable rod 782 to rotate to a position limited by the top of the second movable rod mounting plate 7832. The first movable rod mounting plate 7831 is provided with two mounting holes, one for rotatably mounting the movable rod 782 and the other for mounting a reaction spring 785.

[0141] Another improvement of this application is that the operating mechanism is further provided with a toggle member limiting mechanism 9, which is used to limit the toggle member 4 to the corresponding position when it moves to the first position, and / or the second position, and / or the middle position, thereby limiting the flipping member 3 to the corresponding position as well, thereby improving reliability and safety.

[0142] like Figure 3b , Figure 5a As shown, the toggle member limiting mechanism 9 includes a first limiting shaft 1021 and a second limiting shaft 1022 disposed on the bracket 102. The first limiting shaft 1021 and the second limiting shaft 1022 are fixedly disposed between the first side plate 103 and the second side plate 104. The toggle member 4, as shown... Figure 3b When the toggle element is rotated clockwise to the first position, it is stopped by the first limiting shaft 1021 and cannot continue to rotate clockwise. (The text abruptly ends here, likely due to an incomplete sentence or a formatting error.) Figure 7bWhen the toggle member rotates counterclockwise to the second position, it is stopped by the second limiting shaft 1022 and cannot continue to rotate counterclockwise. Alternatively, the second side plate sliding groove 1041 on the bracket 102 and the third actuating part 44 on the toggle member 4 can cooperate to limit the toggle member 4 to the first and second positions. Figure 4c ).

[0143] In particular, such as Figure 2a , Figure 2d , Figure 3a , Figure 5a , Figure 5b , Figure 6a As shown, the toggle member limiting mechanism 9 includes a first limiting plate 91, a second limiting plate 92, a first limiting plate reset member 93, and a second limiting plate reset member 94. The first limiting plate reset member 93 is connected to the first limiting plate 91, driving the first limiting plate 91 to move away from the toggle member 4 to avoid the toggle member 4. The second limiting plate reset member 94 is connected to the second limiting plate 92, driving the second limiting plate 92 to move away from the toggle member 4 to avoid the toggle member 4.

[0144] When the flipping member 3 rotates from the first position to the middle position, the actuating member 4 rotates from the first position to the middle position. The flipping member 3 drives the first energy storage mechanism 1 to store energy and pass the equilibrium position. The first energy storage mechanism 1 drives the first limiting plate 91 to move closer to the actuating member 4, and the limiting plate limiting part 9120 of the first limiting plate 91 limits the actuating member 4 to the middle position, so that the actuating member 4 cannot continue to rotate to the second position. Figure 5b The first energy storage mechanism 1, having passed the equilibrium position, releases energy, causing the main shaft 6 to rotate to the double-split position. The first energy storage mechanism 1 also avoids the first limiting plate 91. The first limiting plate reset component 93 drives the first limiting plate 91 to move, releasing the limiting effect on the toggle component 4. Figure 2a Subsequently, the toggle element 4 can be operated to rotate to the second position or the first position.

[0145] Similarly, when the flipping member 3 rotates from the second position to the middle position, the actuating member 4 rotates from the second position to the middle position. The flipping member 3 drives the second energy storage mechanism 2 to store energy and pass the equilibrium position. The second energy storage mechanism 2 drives the second limiting plate 92 to move closer to the actuating member 4, and the limiting plate limiting part 9120 of the second limiting plate 92 limits the actuating member 4 to the middle position, preventing the actuating member 4 from continuing to rotate towards the first position. The second energy storage mechanism 2, having passed the equilibrium position, releases energy, driving the main shaft 6 to rotate to the double-split position, and the second energy storage mechanism 2 avoids the second limiting plate 92. Figure 2aThe second limit plate reset component 94 drives the second limit plate 92 to move and release the limit on the toggle component 4. Subsequently, the toggle component 4 can be operated to rotate to the second position or the first position of the toggle component.

[0146] The operating mechanism of this embodiment is provided with a toggle member limiting mechanism 9. When the first energy storage mechanism 1 and the second energy storage mechanism 2 reach the equilibrium position, the toggle member limiting mechanism 9 is driven to limit the toggle member 4 to the middle position of the toggle member and also to limit the flipping member 3 to the middle position of the flipping member 3. Then, the energy release action of the first energy storage mechanism 1 and the second energy storage mechanism 2 avoids the toggle member limiting mechanism 9, and releases the limitation on the toggle member 4, so that it can move to the first position and the second position of the toggle member, thereby improving the reliability and safety of the operating mechanism.

[0147] In this embodiment, the first energy storage mechanism 1 and the second energy storage mechanism 2 each include a linkage mechanism and an energy storage spring. The linkage mechanisms of the first energy storage mechanism 1 and the second energy storage mechanism 2 are the first linkage mechanism 12 and the second linkage mechanism 22, respectively. The energy storage springs of the first energy storage mechanism 1 and the second energy storage mechanism 2 are the first energy storage spring 11 and the second energy storage spring 21, respectively. The first energy storage mechanism 1 cooperates with the first limiting plate 91 through the first linkage mechanism 12, driving the first limiting plate 91 to move closer to the actuating member 4 or avoid the first limiting plate 91. The second energy storage mechanism 2 cooperates with the second limiting plate 92 through the second linkage mechanism 22, driving the second limiting plate 92 to move closer to the actuating member 4 or avoid the second limiting plate 92.

[0148] When the actuating member 4 moves from the first position to the middle position, the first linkage mechanism 12 rotates to drive the first energy storage spring 11 to store energy and pass the equilibrium position. The first linkage mechanism 12 drives the first limiting plate 91 to move towards the actuating member 4 against the force of the first limiting plate reset member 93, so that the limiting plate limiting part 9120 is located on the moving trajectory of the actuating member 4, positioning the actuating member 4 in the middle position. After the first linkage mechanism 12 passes the equilibrium position, the first energy storage spring 11 releases energy and drives the first linkage mechanism 12 to continue rotating. The first linkage mechanism 12 avoids the first limiting plate 91. The first limiting plate reset member 93 drives the first limiting plate 91 to make the limiting plate limiting part 9120 avoid the actuating member 4, so that the actuating member 4 can rotate to the first position and the second position. When the actuating member 4 moves from the second position to the middle position, the second linkage mechanism 22 rotates to drive the second energy storage spring 21 to store energy and pass the equilibrium position. The second linkage mechanism 22 drives the second limiting plate 92 to move towards the actuating member 4 against the force of the second limiting plate reset member 94, so that the limiting plate limiting part 9120 is located on the moving trajectory of the actuating member 4 and positions the actuating member 4 at the middle position. After the second linkage mechanism 22 passes the equilibrium position, the second energy storage spring 21 releases energy and drives the second linkage mechanism 22 to continue rotating. The second linkage mechanism 22 avoids the second limiting plate 92. The second limiting plate reset member 94 drives the second limiting plate 92 to make the limiting plate limiting part 9120 avoid the actuating member 4, so that the actuating member 4 can rotate to the first position and the second position.

[0149] For details, please refer to Figure 2a , Figure 14 The first limiting plate 91 and the second limiting plate 92 have the same structure and are plate-shaped. The first end of the first limiting plate 91 and the second limiting plate 92 are provided with a limiting plate rotation hole 9124, which can be rotatably mounted on the bracket 102. The second end is provided with a limiting plate sliding groove 9122, which is sleeved on the limiting plate limiting shaft of the bracket 102 to limit the rotation angle of the first limiting plate 91 and the second limiting plate 92. One end of the first limiting plate reset member 93 and the second limiting plate reset member 94 are respectively connected to the second end of the first limiting plate 91 and the second limiting plate 92, and the other end is connected to the bracket 102 to drive the first limiting plate 91 and the second limiting plate 92 to rotate away from the toggle member 4. Obviously, in other embodiments, the limiting plate sliding groove 9122 may not be provided. Instead, the limiting protrusion on the bracket 102 may be provided to limit the rotation angle of the first limiting plate 91 and the second limiting plate 92. The first limiting plate reset member 93 and the second limiting plate reset member 94 may not be tension springs, but may be torsion springs, sheet springs or other elastic members.

[0150] The first limiting plate 91 and the second limiting plate 92 have actuation grooves 9121 on their sides facing the actuating member 4, which are used to cooperate with the first actuating part 42 and the second actuating part 43 of the actuating member 4. One side wall of the actuating groove 9121 serves as the limiting plate limiting part 9120, which is used to limit the actuating member 4 to the middle position of the actuating member. The first limiting plate 91 and the second limiting plate 92 have limiting plate driving surfaces 9123 on their sides away from the actuating member 4, i.e., on their sides facing the linkage mechanism, which are used to cooperate with the limiting plate driving part 1211 on the driven plate of the corresponding linkage mechanism (e.g., ...). Figure 10b The first energy storage mechanism 1 and the second energy storage mechanism 2 are driven by the limiting plate driving surface 9123 to rotate the corresponding first limiting plate 91 and second limiting plate 92 toward the actuating member 4. Preferably, the limiting plate driving surface 9123 is an arc surface, and the actuating member groove 9121 is an arc-shaped groove. Of course, as another embodiment, the actuating member groove 9121 may not be provided, and a protrusion may be directly provided as the limiting plate limiting part 9120.

[0151] See Figure 2a , Figure 10a and Figure 10b The first linkage mechanism 12 and the second linkage mechanism 22 each include a pulling plate and a receiving plate. The pulling plate and the receiving plate of the first linkage mechanism 12 are respectively a first receiving plate 121 and a first pulling plate 122, and the pulling plate and the receiving plate of the second linkage mechanism 22 are respectively a second receiving plate 221 and a second pulling plate 222. Both the first receiving plate 121 and the second receiving plate 221 are provided with a limiting plate driving part 1211. The first linkage mechanism 12 and the second linkage mechanism 22 drive the limiting plate driving surface 9123 (e.g., ...) through the limiting plate driving part 1211 of their respective receiving plates. Figure 14 The first limiting plate 91 and the second limiting plate 92 are rotated toward the actuating member 4, causing the first actuating part 42 of the actuating member 4 to enter the actuating member groove 9121 of the first limiting plate 91 or the second actuating part 43 of the actuating member 4 to enter the actuating member groove 9121 of the second limiting plate 92. When the actuating member 4 is rotated to the middle position of the actuating member, the first actuating part 42 slides and is limited by the limiting plate limiting part 9120 of the first limiting plate 91, or the second actuating part 43 slides and is limited by the limiting plate limiting part 9120 of the second limiting plate 92.

[0152] See Figure 10a , 10bThe first driven plate 121 and the second driven plate 221 each include two driven pieces 1214 arranged at relative intervals. The two driven pieces 1214 are connected by a plurality of driven piece fixed shafts. A limiting plate driving part 1211 is also provided between the two driven pieces 1214. At least part of the first limiting plate 91 (such as the limiting plate driving surface 9123) extends between the two driven pieces 1214 of the first driven plate 121 and cooperates with the limiting plate driving part 1211. At least part of the second limiting plate 92 (such as the limiting plate driving surface 9123) extends between the two driven pieces 1214 of the first driven plate 121 and cooperates with the limiting plate driving part 1211, thereby improving reliability and avoiding misalignment. In this embodiment, the limiting plate driving part 1211 consists of two fixed shafts 1211a and 1211b disposed on the driven plate. Of course, the limiting plate driving part 1211 can also be an arc-shaped rib or other similar or similar structures. Anything that can be conceived by those skilled in the art falls within the protection scope of this application.

[0153] The following description, in conjunction with the accompanying drawings, illustrates the process of the actuating element 4 engaging with the first limiting plate 91. The process of the actuating element 4 engaging with the second limiting plate 91 is similar:

[0154] like Figure 4b As shown, when the actuating member 4 is in the first position, the shaft 1211a of the limiting plate driving part 1211 of the first driven plate 121 drives the first limiting plate 91 to rotate towards the actuating member 4 through the limiting plate driving surface 9123, overcoming the force of the first limiting plate reset member 93. This causes the first actuating part 42 of the actuating member 4 to be located in the actuating member groove 9121. When the actuating member 4 moves from the first position to the middle position, the flipping member 3 moves from the first position to the middle position, and the flipping member 3 drives the first linkage mechanism 12 to rotate to drive the first... The energy storage spring 11 stores energy and passes the equilibrium position. The first driven plate 121 rotates and the shaft 1211b of the limiting plate driving part 1211 is kept in the direction of driving the first limiting plate 91 to rotate closer to the toggle member 4 through the limiting plate driving surface 9123. The first toggle part 42 of the toggle member 4 slides in the toggle member groove 9121 and moves to the point where one end of the toggle member groove 9121 is limited by the side wall of the limiting plate limiting part 9120, limiting the toggle member 4 to the middle position of the toggle member, so that the toggle member 4 cannot continue to rotate to the second position of the toggle member.

[0155] The first energy storage spring 11, after passing the equilibrium position, releases energy to drive the first linkage mechanism 12 to continue rotating. The first driven plate 121 rotates and drives the main shaft 6 to rotate to the double split position. The limiting plate driving part 1211 of the first driven plate 121 is misaligned with the limiting plate driving surface 9123 of the first limiting plate 91. The first limiting plate reset part 93 drives the first limiting plate 91 to rotate, releasing the limitation on the toggle member 4. Subsequently, the toggle member 4 can be operated to rotate to the second position or the first position.

[0156] like Figure 2a As shown, when the actuating member 4 is in the middle position, neither the first limiting plate 91 nor the second limiting plate 92 limits the actuating member 4. That is, the first actuating part 42 and the second actuating part 43 of the actuating member 4 are located outside the actuating member slide groove 9121 of the first limiting plate 91 and the second limiting plate 92, respectively.

[0157] like Figure 4b As shown, when the actuating member 4 rotates from the middle position to the first position, the actuating member 4 is limited by the first limiting shaft 1021 on the bracket 102. The flipping member 3 rotates and drives the first linkage mechanism 12 to rotate to drive the first energy storage spring 11 to store energy and pass the equilibrium position. The first energy storage spring 11 that has passed the equilibrium position drives the first linkage mechanism 12. The limiting plate driving part 1211 of the first driven plate 121 of the first linkage mechanism 12 drives the first limiting plate 91 to overcome the force of the first limiting plate reset member 93 and rotate towards the actuating member 4 through the limiting plate driving surface 9123. This causes the first actuating part 42 of the actuating member 4 to be located in the actuating member slide groove 9121 near the middle position. There is a gap between the first actuating part 42 and the limiting plate limiting part 9120 of the first limiting plate 91. At this time, one side wall of the actuating member slide groove 9121 does not limit the actuating member 4.

[0158] The process of the actuating member 4 rotating from the second position to the middle position is similar. When the flipping member 3 rotates from the middle position to the second position, the actuating member 4 rotates from the middle position to the second position. The flipping member 3 drives the second energy storage mechanism 2 to store energy and pass the balance position. The second energy storage mechanism 2, after passing the balance position, releases energy and drives the main shaft 6 to rotate to the auxiliary power supply closing position. It also drives the second limiting plate 92 to rotate towards the actuating member 4. The second actuating part 43 of the actuating member 4 is located in the actuating member slide groove 9121 near the middle position. There is a gap between the second actuating part 43 and the limiting plate limiting part 9120 of the second limiting plate 92.

[0159] It should be noted that the actuating element 4, the actuating element limiting mechanism 9, the automatic operating mechanism, and the main shaft locking mechanism 5 of this application are not only applicable to the energy storage mechanism of this embodiment, but also applicable to energy storage mechanisms of other structures, such as some energy storage mechanisms listed in the background art.

[0160] like Figure 1 , Figure 2aAs shown, the layout of the operating mechanism in this embodiment is as follows: the bracket 102 includes a first side plate 103 and a second side plate 104; a first energy storage mechanism 1, a second energy storage mechanism 2 and a flipping component 3 are disposed between the first side plate 103 and the second side plate 104; the flipping component 3 is rotatably disposed on the main shaft 6; a first electromagnetic mechanism 7 and a second electromagnetic mechanism 8 are symmetrically disposed on the lower sides of the flipping component 3; and the actuating component 4 is located above the flipping component 3. The first side plate 103 and the second side plate 104 are connected by several fixed shafts, including a first energy storage spring fixing shaft 1023, a second energy storage spring fixing shaft 1024, a first limiting shaft 1021, a second limiting shaft 1022, and a toggle member mounting shaft 1026 for rotating the toggle member 4. One end of the energy storage spring of the first energy storage mechanism 1 or the second energy storage mechanism 2 is rotatably connected to the first energy storage spring fixing shaft 1023 and the second energy storage spring fixing shaft 1024, respectively. The toggle member 4 is rotatably mounted on the toggle member mounting shaft 1026, and its rotation angle is limited by the first limiting shaft 1021 and the second limiting shaft 1022. The first side plate 103 and the second side plate 104 are also provided with a main shaft hole through which the main shaft 6 passes, as well as a structure for mounting the main shaft locking mechanism and the toggle member limiting mechanism.

[0161] Preferably, the first driven plate 121 of the first linkage mechanism 12 and the second driven plate 221 of the second linkage mechanism 22 are mounted on the main shaft 6, and the flipping member 3 is located between the first driven plate 121 and the second driven plate 221; the actuating member 4 is rotatably disposed above the flipping member 3 and is also located between the first side plate 103 and the second side plate 104; the first electromagnetic mechanism 7 and the second electromagnetic mechanism 8 are symmetrically disposed on both sides below the flipping member 3.

[0162] The main shaft locking mechanism 5 is located on the outside of the second side plate 104. The first lever 51, the second lever 52, the first elastic member 53 and the baffle 54 on the main shaft 6 are located on the outside of the second side plate 104. The third actuating part 44 on the actuating member 4 extends from the second side plate sliding groove 1041 on the second side plate 104 to the space between the second end of the first lever 51 and the second end of the second lever 52.

[0163] The actuating element limiting mechanism 9 is disposed between the first side plate 103 and the second side plate 104. The first limiting plate 91, the second limiting plate 92, the first limiting plate reset member 93 and the second limiting plate reset member 94 are all located between the first side plate 103 and the second side plate 104. The actuating element 4 is located between the first limiting plate 91 and the second limiting plate 92 of the actuating element limiting mechanism 9. In the vertical direction, the first limiting plate 91 is located between the actuating element 4 and the first driven plate 121, and the second limiting plate 92 is located between the actuating element 4 and the second linkage mechanism 22.

[0164] like Figure 9bAs shown, the flipping component 3 includes two flipping plates 30 arranged opposite to each other. A third linkage part 35 and a fourth linkage part 36 are provided between the two flipping plates 30. The first moving rod 72 of the first electromagnetic mechanism 7 and the second moving rod 82 of the second electromagnetic mechanism 8 extend between the two flipping plates 30 and cooperate with the third linkage part 35 and the fourth linkage part 36.

[0165] like Figure 10a , Figure 10b As shown, the first driven plate 121 and the second driven plate 221 each include two driven pieces 1214 arranged opposite to each other. A limiting plate driving part 1211 is provided between the two driven pieces 1214. The first limiting plate 91 can at least partially extend between the two driven pieces 1214 of the first driven plate 121, and the second limiting plate 92 can at least partially extend between the two driven pieces 1214 of the second driven plate 221.

[0166] The first side plate 103 and the second side plate 104 are mounted on the base 101. The left and right sides of the first side plate 103 and the second side plate 104 are provided with electromagnetic component mounting notches corresponding to the electromagnetic components of the first electromagnetic mechanism 7 and the second electromagnetic mechanism 8. The electromagnetic components of the first electromagnetic mechanism 7 and the second electromagnetic mechanism 8 are mounted on the base 101 and are correspondingly mounted at the electromagnetic component mounting notches. The moving rods 782 of the first electromagnetic mechanism 7 and the second electromagnetic mechanism 8 extend into the first side plate 103 and the second side plate 104 and move in the left and right direction to drive the flip plate 3 to rotate.

[0167] like Figure 9a and Figure 9b As shown, this is one embodiment of the flipper 3 described in this application. The flipper 3 has a circular hole in its middle region, serving as a flipper mounting hole 33, allowing it to be rotatably mounted on the main shaft 6. Two hollowed-out arc-shaped grooves are respectively formed on the lower sides of the flipper 3, serving as the first arc-shaped groove 31 and the second arc-shaped groove 32. Multiple gear teeth are formed at the top of the flipper 3, creating a first linkage part 34 with a gear structure, used for linkage connection with the actuating part 4. A convex shaft is provided on the flipper 3 as a third linkage part 35 and a fourth linkage part 36, used for driving cooperation with the first electromagnetic mechanism 7 and the second electromagnetic mechanism 8. Preferably, the flipping component 3 in this embodiment includes two identical flipping plates 30. Each flipping plate 30 is provided with a flipping component mounting hole 33, a first arc groove 31, a second arc groove 32, and a first linkage part 34. The two flipping plates 30 are arranged opposite each other at intervals and connected by at least two fixed shafts. There is a gap between the two flipping plates 30, and there are three fixed shafts in between. Two of the fixed shafts serve as the third linkage part 35 and the fourth linkage part 36, respectively. The moving rod driving part 7822 of the two moving rods 782 of the first electromagnetic mechanism 7 and the second electromagnetic mechanism 8 extends between the two flipping plates 30 and cooperates with the third linkage part 35 and the fourth linkage part 36.

[0168] like Figure 13 As shown, this is one embodiment of the actuating component 4. The actuating component 4 includes an actuating component pivot part 40 with a rotating hole. The top of the actuating component pivot part 40 has a protruding actuating component driving part 45, and the bottom is a fan-shaped structure centered on the rotating hole. The arc side of the fan-shaped structure has a gear as a second linkage part 41 for cooperating with the flipping component 3. The two sides of the fan-shaped structure have arc-shaped limiting grooves 46 for cooperating with the first limiting shaft 1021 and the second limiting shaft 1022 on the bracket 102. The actuating component driving part 45 is a hole-like structure for driving by inserting a driving rod. When the actuating element 4 rotates, a third actuating part 44 protrudes from one side of the fan-shaped structure. The third actuating part 44 is located directly below the pivot part 40 of the actuating element and is used to drive and cooperate with the first lever 51 and the second lever 52 of the main shaft locking mechanism 5 to realize the locking function of the actuating element. The two sides of the fan-shaped structure are also provided with a first actuating part 42 and a second actuating part 43 respectively. The protrusion direction of the third actuating part 44, the first actuating part 42 and the second actuating part 43 is parallel to the rotation axis of the actuating element 4, and the third actuating part 44 is located between the first actuating part 42 and the second actuating part 43.

[0169] To better understand this application, the operation process of the embodiments of this application is described below.

[0170] The following describes the process of an automatic transfer switch switching from the open position to the standby power supply closed position:

[0171] Figure 2a , Figure 2b , Figure 2c , Figure 6a , Figure 6b as well as Figure 6c A schematic diagram of the internal structure changes of the operating mechanism of this application during the conversion process is shown. As shown in the figure, during the conversion process, the second electromagnetic mechanism 8 is activated, the second electromagnetic component 81 is energized, the second moving rod 82 retracts to the left, and after the movement travels to a certain distance, the moving rod drive part 7822 on the second moving rod 82 contacts the fourth linkage part 36 of the flip plate 3 and pulls the fourth linkage part 36 to move to the left, driving the flip plate 3 to rotate clockwise.

[0172] During the clockwise rotation of the flip plate 3, one end wall of the second arc groove 32 pulls the second connecting rod shaft 223, thereby driving the second connecting rod mechanism 22 to rotate clockwise. This, in turn, pulls the second energy storage spring 21 through the second pulling plate 222, increasing the spring length and accumulating elastic potential energy (such as...). Figure 6a , Figure 6b (As shown); the second linkage mechanism 22 continues to rotate clockwise until the force direction of the second energy storage spring 21, the center point of the main shaft 6, and the second linkage shaft 223 are on the same straight line. Figure 6c As shown), at this time, the torque generated by the second energy storage spring 21 on the main shaft 6 is 0, and the second linkage mechanism 22 is in the equilibrium position (dead point position); during the process of the second linkage mechanism 22 gradually rotating from the double split position to the dead point position, the driven part 1213 of the driven plate 221 of its second driven plate 221 moves closer to the main shaft linkage part 61 of the main shaft 6; the second electromagnetic component 81 continues to pull the flipping plate 3 to rotate clockwise, causing the second linkage mechanism 22 to rotate past the dead point position, and the elastic potential energy accumulated by the second energy storage spring 21 is released. During the release process, the second linkage mechanism 22 continues to be pulled. When rotated clockwise, the second linkage shaft 223 of the second linkage mechanism 22 slides within the second arc groove 32 of the flip plate 3. At this time, the driven part 1213 of the driven plate 221 of the second driven plate 221 contacts the main shaft linkage part 61 of the main shaft 6. The second linkage mechanism 22 drives the main shaft 6 to rotate clockwise. The main shaft 6 reaches its maximum clockwise rotation angle position (i.e., the backup power supply closing position of the automatic transfer switch). The second linkage shaft 223 slides to the other end of the second arc groove 32 and is limited. The second driven plate 221 of the second linkage mechanism 22 is limited by the second driven plate limiting part.

[0173] Due to the linkage between the flip plate 3 and the actuating member 4, when the flip plate 3 reaches its maximum clockwise rotation position, the limiting plate driving part 1211 of the second driven plate 221 drives the second limiting plate 92 to rotate closer to the actuating member 4. This causes the second actuating part 43 of the actuating member 4 to be limited by one end of the actuating member groove 9121 of the second limiting plate 92, preventing it from rotating counterclockwise. At this time, the actuating member 4 also reaches its maximum counterclockwise rotation angle position (e.g., Figure 7a As shown), the third actuating part 44 of the actuating member 4 is linked to the first lever 51, rotating clockwise by a certain angle, causing the first lever locking part 512 to disengage from the baffle 54, and the third actuating part 44 to disengage from the second lever 52. After the second energy storage spring 21 releases its energy, it drives the second linkage mechanism 22 to rotate the main shaft 6 clockwise. At this time, the second driven plate 221 releases its drive on the second limiting plate 92, and under the action of the return spring, it rotates away from the actuating member 4. The actuating member slide groove 9121 releases its limit on the second actuating part 43, and the baffle 54 rotates with the main shaft 6. Under the action of the first elastic member 53, the second lever locking part 522 of the second lever 52 contacts the second locking part 542 of the baffle 54, and limits the baffle 54, preventing the main shaft 6 from reversing (as shown). Figure 7b (As shown); After the automatic transfer switch completes the backup power closing position, the second electromagnetic component 81 extends to the right and resets under the action of the moving rod spring 784 and the reaction spring 785 on its corresponding side, and is finally limited by the limiting part on the bracket 102.

[0174] The following describes the process of an automatic transfer switch switching from the standby power supply closed position to the double open position:

[0175] like Figure 8a , Figure 8b A schematic diagram showing the structural changes of the internal structure of the operating mechanism during the conversion process is shown, as follows: Figure 8a , Figure 8b As shown, after the automatic switch is in the standby power supply closed position, when it switches to the double open position, the first electromagnetic mechanism 7 is activated, the first electromagnetic component 71 is energized, and the first electromagnetic component 71 pulls the first moving rod 72 to retract to the right. After the movement travels a certain distance, the moving rod drive part 7822 on the first moving rod 72 contacts the fourth linkage part 36 of the flip plate 3 and pulls the fourth linkage part 36 to move to the right, driving the flip plate 3 to rotate counterclockwise.

[0176] During the counterclockwise rotation of the flip plate 3, the other end wall of the second arc groove 32 pulls the second connecting rod shaft 223, thereby driving the second connecting rod mechanism 22 to rotate counterclockwise. This, in turn, pulls the second energy storage spring 21 through the second pulling plate 222, increasing the spring length and accumulating elastic potential energy (such as...). Figure 8a (As shown); the second linkage mechanism 22 continues to rotate counterclockwise until the force direction of the second energy storage spring 21, the center point of the main shaft 6, and the second linkage shaft 223 are on the same straight line. At this time, the torque generated by the second energy storage spring 21 on the main shaft 6 is 0, and the second linkage mechanism 22 is in the equilibrium position (dead point position) (as shown). Figure 8a As shown in the figure; during the process of the second linkage mechanism 22 gradually rotating from the backup power closed position to the equilibrium position, the driven part 1213 of the second driven plate 221 moves closer to the main shaft linkage part 61 of the main shaft 6.

[0177] The first electromagnetic component 71 continues to pull the flip plate 3 to rotate counterclockwise, causing the second linkage mechanism 22 to rotate past the dead point position. The elastic potential energy stored in the second energy storage spring 21 is released. During the release process, the second linkage mechanism 22 continues to rotate counterclockwise. The second linkage shaft 223 of the second linkage mechanism 22 slides in the second arc groove 32 of the flip plate 3. At this time, the driven part 1213 of the driven plate 221 of the second driven plate 221 contacts the main shaft linkage part 61 of the main shaft 6. The second linkage mechanism 22 drives the main shaft 6 to rotate counterclockwise. The main shaft 6 reaches the middle position of left and right rotation (i.e., the double position of the automatic changeover switch). Finally, the second linkage mechanism 22 is limited by one end side wall of the second arc groove 32 of the flip plate 3, and the second driven plate 221 of the second linkage mechanism 22 is limited by another second driven plate limiting part.

[0178] Due to the linkage between the flip plate 3 and the actuating member 4, when the flip plate 3 is in the center of its left and right rotatable angles, the actuating member 4 is also in the center of its left and right rotatable angles. Before the second energy storage spring 21 releases its energy, the first lever 51 and the second lever 52, under the action of the first elastic member 53, have their locking parts 512 in contact with the baffle 54, and their locking parts 522 and 542 are released. After the second energy storage spring 21 releases its energy, it drives the second linkage mechanism 22 to rotate the main shaft 6 to the double-split position. Finally, the baffle 54 is in the middle position of left and right rotation, and the locking parts 512 and 522 of the first lever simultaneously contact the arc-shaped edge of the baffle 54. The ends of the first lever 51 and the second lever 52 simultaneously contact the third actuating part 44 of the actuating member 4 (e.g., ...). Figure 2d (as shown);

[0179] After the first electromagnetic component 71 retracts to its maximum distance position to the right, and the automatic transfer switch completes the switchover from the standby power supply closed position to the double open position, the power supply to the first electromagnetic component 71 is cut off. The first moving rod 72 extends to the left to reset under the action of the moving rod spring 784 and the reaction spring 785 on its corresponding side. During this process, the hook portion slope 7824 of the first moving rod 72 touches the fourth linkage part 36. Due to the inclined surface structure design of the hook portion slope 7824, the hook portion slope 7824 will slide under the fourth linkage part 36. Finally, due to the action of the moving rod spring 784 and the reaction spring 785, the first electromagnetic component 71 is limited by the limiting part on the bracket 102, and the moving rod drive part 7822 is located on the left side of the fourth linkage part 36.

[0180] Figures 2a-4c The process of the automatic transfer switch switching from the open position to the main power supply closed position is shown, as follows: Figures 2a-4c As shown, during this process, the first electromagnetic mechanism 7 activates, and its first moving rod 72 pulls the flip plate 3 to rotate counterclockwise, thereby driving the first linkage mechanism 12 to rotate counterclockwise. The first linkage mechanism 12 pulls the first energy storage spring 11 to complete energy storage, and after passing the equilibrium position, the first energy storage spring 11 releases energy and pulls the first linkage mechanism 12 to rotate counterclockwise. The first linkage mechanism 12 drives the main shaft 6 to rotate counterclockwise, completing the main power supply position closing action. The process of the automatic transfer switch switching from the dual-open position to the main power supply closed position is similar to the process of switching from the dual-open position to the standby power supply closed position, and will not be described in detail here.

[0181] Figure 5a , Figure 5b as well as Figure 5c The diagram illustrates the process of the automatic transfer switch switching from the open position to the main power supply closed position, as shown below. Figure 5a , Figure 5b as well as Figure 5c As shown, during this process, the second electromagnetic mechanism 8 activates, and the second moving rod 82 of the second electromagnetic mechanism 8 pulls the flip plate 3 to rotate clockwise, thereby driving the first linkage mechanism 12 to rotate clockwise. The first linkage mechanism 12 pulls the first energy storage spring 11 to complete energy storage, and after passing the equilibrium position, the first energy storage spring 11 releases energy and pulls the first linkage mechanism 12 to rotate clockwise. The first linkage mechanism 12 drives the main shaft 6 to rotate clockwise, completing the tripping action. The process of the automatic transfer switch switching from the main power closed position to the double-open position is similar to the process of switching from the standby power closed position to the double-open position, and will not be described in detail here.

It also has multiple limit and protection mechanisms to prevent operators from making operational errors during use, damaging power supply equipment, or endangering personal safety.
