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 a vital support for modern social, economic, and social development, power transmission and distribution systems play an irreplaceable role. Transfer switches, as important components within these systems, fulfill crucial functions, especially in hospitals, intelligent buildings, data centers, power plants, banks, and critical infrastructure where uninterrupted, reliable, stable, and continuous power output is required.

[0003] Existing technologies such as CN111986938A, CN109786146A, CN109686598A, CN113838694A, and CN113611553A all disclose different changeover switches.

[0004] This application aims to provide a novel operating mechanism for a changeover switch. Furthermore, existing operating mechanisms for changeover switches suffer from the following problems:

[0005] (1) 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.

[0006] (2) 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.

[0007] (3) The operating mechanism lacks a limit mechanism for dual-position operation, resulting in poor reliability.

[0008] (4) 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

[0009] The purpose of this invention is to overcome the limitations of providing a novel operating mechanism for a changeover switch, which can achieve three-position switching and whose switching speed is independent of the speed of the manual and automatic operating mechanisms.

[0010] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] An operating mechanism for a changeover switch includes an energy storage mechanism for driving a main shaft. The energy storage mechanism includes a first energy storage mechanism, a second energy storage mechanism, and a flipping component. The flipping component can rotate to a first flipping component position, a middle flipping component position, and a second flipping component position, respectively for driving the main shaft to rotate to the main power supply closed position, the dual open position, and the backup power supply closed position.

[0012] The flipping component is rotatably configured and is provided with 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.

[0013] When the flipping component rotates from the middle position to the first position, or from the first position to the middle position, 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.

[0014] When the flipping component rotates from the middle position to the second position, or from the second position to the middle position, the rotation of the flipping component drives the connecting shaft of the second energy storage mechanism through the second arc groove, thereby causing the connecting rod 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 connecting rod mechanism of the second energy storage mechanism to move, thereby driving the main shaft to rotate.

[0015] Preferably, the flipping component is rotatably mounted on the main shaft.

[0016] Preferably, the driven plate is provided with a driven plate rotation hole, and a driven plate driving part is provided in the driven plate rotation hole. A main shaft linkage part is provided on the main shaft. The driven plate is sleeved on the main shaft through the driven plate rotation hole. The driven plate can rotate around the main shaft. After the driven plate contact and limit the main shaft, the driven plate drives the main shaft to rotate.

[0017] Preferably, the first end of the pulling plate is connected to the energy storage spring, and the second end is connected to the driven plate. A bending portion is provided between the first end and the second end of the pulling plate, so that the pulling plate has a V-shaped structure or a U-shaped structure.

[0018] Preferably, the driven plate includes a driven plate rotating part, the driven plate rotating part is provided with a driven plate rotating hole in the middle, the driven plate connecting part is provided on the radially outer side of the driven plate rotating part, the driven plate connecting part is hinged to the second end of the pulling plate through a connecting rod shaft, and a protruding structure is provided in the driven plate rotating hole as a driven plate driving part.

[0019] Preferably, the driven plate includes two driven pieces arranged at relative intervals, the second end of the pulling plate extends between the two driven pieces, and the connecting rod shaft passes through the two driven pieces and the second end of the pulling plate to hinge the driven plate and the pulling plate.

[0020] Preferably, the first energy storage mechanism and the second energy storage mechanism are arranged symmetrically, and the energy storage springs of the first energy storage mechanism and the second energy storage mechanism are respectively located on both sides of the axis of symmetry. The first end of the energy storage spring and the pull plate of the first energy storage mechanism, and the second end of the pull plate of the second energy storage mechanism are located on one side of the axis of symmetry, and the first end of the energy storage spring and the pull plate of the second energy storage mechanism, and the second end of the pull plate of the first energy storage mechanism are located on the other side of the axis of symmetry.

[0021] Preferably, the energy storage spring, the rotation axis of the driven plate, and the connecting rod axis of the first energy storage mechanism are located on the same straight line to form the equilibrium position of the first energy storage mechanism; the energy storage spring, the rotation axis of the driven plate, and the connecting rod axis of the second energy storage mechanism are located on the same straight line to form the equilibrium position of the second energy storage mechanism.

[0022] Preferably, the support of the operating mechanism is provided with a first link limiting part and a second link limiting part, which are respectively used to limit the rotation position of the driven plate after the first energy storage mechanism and the second energy storage mechanism release energy.

[0023] Preferably, it further includes an automatic operating mechanism, which includes a first electromagnetic mechanism and a second electromagnetic mechanism. Each of the first and second electromagnetic mechanisms includes an electromagnetic component and a moving rod connected to the electromagnetic component. When the electromagnetic component is energized, it drives the moving rod to rotate the flipping component. And / or, it further includes a manual operating mechanism, which includes a rotatably configured toggle member connected to the flipping component to drive the flipping component to rotate.

[0024] This invention provides a novel operating mechanism for a three-position rotary switch. A flip-up component is rotatably configured and has a first and a second arcuate groove. Both the first and second energy storage mechanisms 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 via a linkage shaft. The receiving plate is rotatably configured and connected to a main shaft. When the flip-up component rotates, it drives the first energy storage mechanism or the second energy storage mechanism via a linkage shaft driven by one of the two sidewalls of the first or second arcuate groove. The linkage mechanism of the second energy storage mechanism moves, causing 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 linkage 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, which can ensure that the operating mechanism can quickly drive the main shaft 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.

Detailed Implementation

[0056] 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.

[0057] 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 both a main power supply and a backup power supply. Rotation of the spindle 6 causes the switch contact system to switch between main power supply to the load and backup power supply to the load. For a three-position changeover switch, the operating mechanism drives the spindle 6 to rotate between three positions: main power supply closed, double open, and backup power supply closed. When the spindle 6 rotates to the main power supply closed, double open, or backup power supply closed positions, it causes the switch contact system to switch to the main power supply on state, the main power supply and backup power supply both off state, or the backup power supply on state, respectively.

[0058] 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.

[0059] The flipping component 3 can rotate to a first position, a middle position, and a second position, respectively, to drive the main shaft 6 to rotate to the main power supply closed position, the dual-open position, and the backup power supply closed position. When the flipping component 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 supply closed position or dual-open position. When the flipping component 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 supply closed position or dual-open position. This is the prior art in this field.

[0060] like Figure 1 , Figure 2aAs 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.

[0061] like Figure 2a , Figure 2bAs shown, one 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.

[0062] 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.

[0063] like Figure 2a , Figure 2b , Figure 9 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.

[0064] 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.

[0065] 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.

[0066] In this way, during the energy storage process, 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. The switching speed of the automatic transfer switch is independent of the speed of the manual and automatic operating mechanisms. This ensures that the operating mechanism can quickly drive the main shaft 6 to switch the power, reduce the burning of the switch contact system by the electric arc, and improve the performance and reliability of the transfer switch.

[0067] 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.

[0068] 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 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. The two do not contact and limit each other, and the main shaft 6 is not driven to rotate during this process. When the flipping member 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 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 in the direction close to the main shaft linkage part 61. The two do not contact and limit each other. This process does not drive the main shaft 6 to rotate.

[0069] 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.

[0070] Specifically, such as Figures 10a-11 As 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.

[0071] like Figure 11 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 are used for the rotation of the driven plate, and the notches in the planar sidewalls serve as spindle clearance notches 62. The connection between the spindle clearance notches 62 and the arc-shaped sidewalls 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 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 12Obviously, 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] The specific operation process of the energy storage mechanism in this embodiment is as follows: Figure 2b , Figure 2c , 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.

[0076] like Figure 2b , Figure 6a , Figure 6b , Figure 7a and Figure 8As 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.

[0077] 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 provided on the bracket 102. Of course, as another embodiment, the first link limiting part 1025 and the second link limiting part may not be provided, and the rotational 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.

[0078] like Figure 10a , 10b As shown, a preferred embodiment of the first linkage mechanism 12 and the second linkage mechanism 22 has the same structure, both including their respective driven plates and pulling plates. The structure of the driven plates and pulling plates is described below using the driven plates and pulling plates of the first linkage mechanism 12 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 is provided on the radially outer side of the driven plate rotating part. The driven plate connecting part is hinged to one end of the first pulling plate 122 through 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 is also provided on the radially outer side of 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 pull plate 122 has a plate-like structure. Its first end is connected to the first energy storage spring 11, and its second end is connected to the first driven plate 121. A bend is present between the first and second ends of the first pull plate 122. In this embodiment, the bend makes the first pull plate 122 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, reduces the rotation distance between the first driven plate 121 and the first pull plate 122, and reduces the space occupied. In other embodiments, the first pull plate 122 may also be a straight structure or have other shapes or multiple bends.

[0079] 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)

[0080] 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.

[0081] 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.

[0082] 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 9 and Figure 13As 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. Preferably, the actuating element 4 is used to drive the indicating mechanism to indicate the state of the operating mechanism. Obviously, as another embodiment, the rotation of the actuating element 4 can drive the rotation of the flipping element 3 in one direction, while the rotation of the flipping element 3 can not drive the actuating element 4, which is also within the scope of protection of this application.

[0083] In this embodiment, as Figure 9 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.

[0084] like Figure 8 and Figure 13As 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.

[0085] 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.

[0086] 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.

[0087] like Figure 2c , 11 as well as Figure 12As 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.

[0088] like Figure 2c , Figure 4c , Figure 5c , Figure 7b 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.

[0089] 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 12 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.

[0090] 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.

[0091] The actuating member 4 is provided with a third actuating part 44 for driving the first lever 51 and the second lever 52. The third actuating part 44 is located between the second end of the first lever 51 and the second end of the second lever 52. The main shaft 6 is provided with a first locking part 541 and a second locking part 542. The side of the first lever 51 with the first lever locking part 512 and the side of the second lever 52 with the second lever locking part 542 are arranged at intervals relative to each other and are located on both sides of the main shaft 6.

[0092] When the actuating element 4 moves to the first position, it drives the second lever 52 to move away from the main shaft 6 and avoids the first lever 51. This causes the first elastic element 53 to drive the first lever 51 to move the first lever locking part 512 towards the main shaft 6. When the main shaft 6 rotates to the main power supply closed position, 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 double-split position.

[0093] When the actuating member 4 moves to the second position, it drives the first lever 51 to move away from the main shaft 6 and avoids the second lever 52, so that the first elastic member 53 drives the second lever 52 to move the second lever locking part 522 closer to 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, so that the main shaft 6 cannot rotate to the double split position.

[0094] When the actuating member 4 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, and the first elastic member 53 drives the second lever 52 to reset; when the actuating member 4 rotates from the second position to the middle position, it drives the second lever 52 to overcome the force of the first elastic member 53 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, and the first elastic member 53 drives the first lever 51 to reset.

[0095] 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.

[0096] like Figure 3b Figure 5 and Figure 15 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 7b When 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 ).in, Figure 15 A schematic diagram of the structure of the bracket 102 is shown.

[0097] In particular, such as Figure 2a , Figure 2c , Figure 3a , Figure 5a , Figure 5b , Figure 6aAs 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.

[0098] 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.

[0099] 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 2a The 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.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] For details, please refer to Figure 2a , Figure 14The 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.

[0104] 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.

[0105] 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 14The first limiting plate 91 and the second limiting plate 92 are rotated towards 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 rotates 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. It should be noted that the first linkage mechanism 12 and the second linkage mechanism 22 are not limited to the pulling plate and the driven plate, but may also include other linkages, or may be structures that do not use the pulling plate and the driven plate, such as the technical solutions in the prior art mentioned in the background art.

[0106] See Figure 10a , 10b The 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.

[0107] 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:

[0108] like Figure 4bAs 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.

[0109] 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.

[0110] 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.

[0111] like Figure 4bAs 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.

[0112] 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.

[0113] 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.

[0114] like Figure 1 , Figure 2aAs shown, in this embodiment, the operating mechanism is arranged such that 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 mounted on the main shaft 6. A first electromagnetic mechanism 7 and a second electromagnetic mechanism 8 are symmetrically arranged on both sides below the flipping component 3. The actuating component 4 is located above the flipping component 3. 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 drives the first energy storage mechanism 1 and the second energy storage mechanism 2 to store energy first, and then releases 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.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] 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. In the figure, the first limiting plate 91 and the second limiting plate 92 are respectively disposed above the first driven plate 121 and the second driven plate 221.

[0119] 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.

[0120] like Figure 9 As shown, this is an embodiment of the flipper 3 described in this application. The flipper 3 has a circular hole in the middle area, which serves as the 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 groove 31 and the second arc groove 32. Multiple gear teeth are formed at the top of the flipper 3, creating a first linkage part 34 of a gear structure, which is used for linkage connection with the actuating member 4. Preferably, the flipper 3 in this embodiment includes two identical flip plates 30. Each flip plate 30 is provided with a flipper mounting hole 33, a first arc groove 31, a second arc groove 32, and a first linkage part 34. The two flip plates 30 are spaced apart and opposite to each other and connected by several fixed shafts.

[0121] like Figure 13As 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.

[0122] It should be noted that in the description of this invention, the terms "upper," "lower," "left," "right," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship conventionally placed during use.

[0123] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
