The transmission structure is either complex, or the function is relatively simple and the reliability is not high, or the layout is unreasonable, resulting in a large size.

[0006] (2) After releasing energy, the energy storage mechanism drives other transmission mechanisms to indirectly drive the main shaft to rotate. There are many transmission elements, the mechanism is complex and occupies a large space.

[0007] (3) The operating mechanism does not have a double-position limit mechanism, resulting in poor reliability.

DETAILED DESCRIPTION

[0056] The following embodiments are given in conjunction with the accompanying drawings to further illustrate the specific implementation of the present utility model. The protection scope of the present utility model is not limited to the description of the following embodiments.

[0057] A transfer switch typically includes an operating mechanism and a switch contact system (not shown). The operating mechanism is connected to the switch contact system via a main shaft 6. The switch contact system is connected to the main power supply and the backup power supply. Rotation of the main shaft 6 drives the switch contact system to switch between the main power supply supplying the load or the backup power supply supplying the load. For a three-position transfer switch, the operating mechanism drives the main shaft 6 to rotate between three positions: the main power closed position, the double open position, and the backup power closed position. When the main shaft 6 rotates to the main power closed position, the double open position, and the backup power closed position, it drives the switch contact system to switch to the main power connected state, the main power and backup power disconnected state, or the backup power connected state, respectively.

[0058] Reference this application Figure 1 、 Figure 2a The operating mechanism of the transfer switch includes an energy storage mechanism connected to the main shaft 6, and 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 flip member 3. The flip member 3 is rotatably arranged. The flip member 3 rotates to drive the first energy storage mechanism 1 or the second energy storage mechanism 2 to store energy first, and after driving the first energy storage mechanism 1 or the second energy storage mechanism 2 to cross 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 quickly rotate and switch positions. The automatic operating mechanism is used to realize remote control to drive the energy storage mechanism to realize power conversion and disconnection, and the manual operating mechanism is used to manually drive the energy storage mechanism to realize power conversion 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 on and off, and the other is used for switching the backup power on and off.

[0059] The flip member 3 can be rotated to the first position of the flip member, the middle position of the flip member and the second position of the flip member, which correspond to driving the main shaft 6 to rotate to the main power closing position, the double-open position and the backup power closing position respectively; when the flip member 3 rotates from the middle position of the flip member to the first position of the flip member, or from the first position of the flip member to the middle position of the flip member, the first energy storage mechanism 1 is driven to store energy first and release energy after crossing the equilibrium position (dead point position), directly or indirectly driving the main shaft 6 to rotate to the corresponding main power closing position or double-open position; when the flip member 3 rotates from the middle position of the flip member to the second position of the flip member, or from the second position of the flip member to the middle position of the flip member, the second energy storage mechanism 2 is driven to store energy first and release energy after crossing the equilibrium position (dead point position), directly or indirectly driving the main shaft 6 to rotate to the corresponding backup power closing position or double-open position, which is the existing technology in this field.

[0060] like Figure 1 、 Figure 2aAs shown, an operating mechanism of this embodiment includes a housing 10 and an energy storage mechanism disposed within the housing 10. The housing 10 of this embodiment includes a base 101 and a bracket 102 disposed on the base 101. The bracket 102 includes a first side plate 103 and a second side plate 104 spaced apart from each other. The first side plate 103 and the second side plate 104 are connected by a plurality of fixed shafts. The energy storage mechanism includes a first energy storage mechanism 1, a second energy storage mechanism 2, and a flip member 3. The first energy storage mechanism 1, the second energy storage mechanism 2, and the flip member 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 the same structure and are symmetrically disposed on either side of the flip member 3. The main shaft 6 is rotatably disposed 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. The first electromagnetic mechanism 7 and the second electromagnetic mechanism 8 are mounted on the base 101 and symmetrically disposed on either side of the flip member 3 to drive the flip member 3 to rotate. The manual operating mechanism of this embodiment includes a toggle member 4, which is connected to the flip member 3 and rotatably disposed between the first side plate 103 and the second side plate 104, for driving the flip member 3 to rotate. In other embodiments, the housing 10 may also be provided with an upper cover to cover the bracket 102; or the bracket 102 may be a relatively closed housing structure; or the base 101 may be omitted, with the first electromagnetic mechanism 7 and the second electromagnetic mechanism 8 also mounted on the bracket 102.

[0061] like Figure 2a 、 Figure 2bAs shown, an improvement of the present application lies in the structural design of the energy storage mechanism, and a new energy storage mechanism is provided, which includes a first energy storage mechanism 1, a second energy storage mechanism 2 and a flip member 3. The flip member 3 is rotatably arranged and is provided with a first circular arc slide 31 and a second circular arc slide 32. The first energy storage mechanism 1 and the second energy storage mechanism 2 each include a connecting rod mechanism and an energy storage spring. The connecting rod mechanism includes a pulling plate and a driven plate. One end of the energy storage spring is rotatably arranged, 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 connecting rod shaft. The driven plate is rotatably arranged and is directly or indirectly connected to the main shaft 6. The connecting rod shafts of the first energy storage mechanism 1 and the second energy storage mechanism 2 are respectively installed in the first circular arc slide 31 and the second circular arc slide 32 of the flip member 3. The connecting rod shafts of the first and second energy storage mechanisms 1 and 2 are capable of sliding within the corresponding first and second circular arc grooves 31 and 32. When the flip member 3 rotates, the corresponding connecting rod shaft is driven through one of the two end sidewalls of the first and second circular arc grooves 31 and 32 to drive the connecting rod mechanism of the first and second energy storage mechanisms 1 and 2 to move. This causes the corresponding energy storage spring to first store energy and then release energy after crossing the equilibrium position, driving the connecting rod mechanism to rotate the main shaft 6, and the connecting rod shaft slides to the other end of the first and second circular arc grooves 31 and 32. The two end sidewalls of the first circular arc groove 31 drive the connecting rod shaft to move in different directions.

[0062] The flip member 3 rotates through the first circular arc slot 31 to drive the connecting rod shaft of the first energy storage mechanism 1 to drive the connecting rod mechanism of the first energy storage mechanism 1 to move, so that the energy storage spring of the first energy storage mechanism 1 first stores energy and releases energy after crossing the equilibrium position. The energy storage spring of the first energy storage mechanism 1 releases energy and drives the connecting rod mechanism of the first energy storage mechanism 1 to move, thereby driving the main shaft 6 to rotate; or, the flip member 3 rotates through the second circular arc slot 32 to drive the connecting rod shaft of the second energy storage mechanism 2 to drive the connecting rod mechanism of the second energy storage mechanism 2, so that the energy storage spring of the second energy storage mechanism 2 first stores energy and releases energy after crossing the equilibrium position. The energy storage spring of the second energy storage mechanism 2 releases energy and drives the connecting rod mechanism of the second energy storage mechanism 2 to drive the main shaft 6 to rotate.

[0063] like Figure 2a 、 Figure 2b 、 Figure 9 As shown, the flip member 3 includes a first arcuate slot 31 and a second arcuate slot 32. In this embodiment, the flip member 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 shaft 6. The connecting rod mechanisms of the first energy storage mechanism 1 and the second energy storage mechanism 2 are respectively the first connecting rod mechanism 12 and the second connecting rod mechanism 22. The energy storage springs of the first energy storage mechanism 1 and the second energy storage mechanism 2 are respectively the first energy storage spring 11 and the second energy storage spring 21. The connecting rod shafts of the first energy storage mechanism 1 and the second energy storage mechanism 2 are respectively the first connecting rod shaft 123 and the second connecting rod shaft 223.

[0064] The pulling plate and the driven plate of the first connecting rod mechanism 12 are respectively the first driven plate 121 and the first pulling plate 122. The first driven plate 121 is rotatably arranged and connected to the main shaft 6. The first driven plate 121 is hinged to one end of the first pulling plate 122 through the first connecting rod shaft 123. The other end of the first pulling 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 fixed shaft 1023 of the bracket 102. The first connecting rod shaft 123 is movably installed in the first arc slide groove 31 of the flip member 3. The flip member 3 drives the first connecting rod shaft 123 through the side wall of one end of the first arc sliding groove 31, driving the first driven plate 121 and the first pulling plate 122 to rotate, so that the first energy storage spring 11 first stores energy. After the first energy storage spring 11 passes the equilibrium position, the first energy storage spring 11 releases energy through the first pulling plate 122 and the first connecting rod shaft 123 to drive the first driven plate 121 to rotate, and the first driven plate 121 drives the main shaft 6 to rotate. The equilibrium position is as shown in FIG. Figure 3b In the example, the rotation axis of the first energy storage spring 11, the first driven plate 121 and the force direction of the first connecting rod shaft 123 are on the same straight line. After the first energy storage spring 11 releases energy, the first connecting rod shaft 123 slides to the side wall of the other end of the first arc groove 31.

[0065] The structure of the second connecting rod mechanism 22 is similar to that of the first connecting rod mechanism 12. The pulling plate and the driven plate of the second connecting rod mechanism 22 are respectively the second driven plate 221 and the second pulling plate 222. The second driven plate 221 is hinged to one end of the second pulling plate 222 through the second connecting rod 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 fixed shaft 1024 of the bracket 102. The second connecting rod shaft 223 is movably installed in the second arc slide groove 32 of the flip member 3. The flip member 3 drives the second connecting rod shaft 223 through the side wall of one end of the second arc slot 32, driving 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 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. After the second energy storage spring 21 releases energy, the second connecting rod shaft 223 slides to the side wall of the other end of the second arc slot 32.

[0066] In this way, the main shaft 6 does not move during the energy storage mechanism storing energy. After the energy storage mechanism releases energy, the main shaft 6 is driven to rotate quickly to switch the power supply. The switching speed of the automatic transfer switch is independent of the speed of the manual operating mechanism and the automatic operating mechanism. It can ensure that the operating mechanism quickly drives the main shaft 6 to switch the power supply, reduce the burning of the switch contact system by the 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, i.e., 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, the driven plates of the first energy storage mechanism 1 and the second energy storage mechanism 2 are both provided with a driven plate rotation hole 1212, and a driven plate driving part 1213 is provided in the driven plate rotation hole 1212. A main shaft linkage part 61 is provided on the main shaft 6. The driven plate is sleeved on the main shaft 6 through the driven plate rotation hole 1212. The driven plate can rotate around the main shaft 6, and after the driven plate driving part 1213 contacts and limits the position with 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 connecting rod 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 and limits the position with the main shaft linkage part 61, the main shaft 6 is driven to rotate. No redundant transmission structure is required, and the structure is simple and compact.

[0068] In particular, when the flip member 3 drives the first energy storage mechanism 1 to store energy first and releases energy after crossing the equilibrium position, when the energy storage spring of the first energy storage mechanism 1 reaches the equilibrium position, or after crossing the equilibrium position, the driven plate driving portion 1213 of the driven plate of the first energy storage mechanism 1 contacts and limits the spindle linkage portion 61, 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 spindle 6, and the driven plate driving portion 1213 moves in a direction close to the spindle linkage portion 61, and the two do not contact and limit, and this process does not drive the spindle 6 to rotate. dynamic; when the flip member 3 drives the second energy storage mechanism 2 to store energy first and releases energy after crossing the equilibrium position, when the energy storage spring of the second energy storage mechanism 2 reaches the equilibrium position, or after crossing the equilibrium position, the driven plate driving part 1213 of the driven plate of the second energy storage mechanism 2 contacts and limits the spindle linkage part 61, 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 spindle 6, and the driven plate driving part 1213 moves in the direction close to the spindle linkage part 61, and the two have no contact limit, and this process does not drive the spindle 6 to rotate.

[0069] Of course, as other inferior embodiments, 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 to rotate synchronously, but this solution requires a large operating force when performing opening and closing operations. As other inferior embodiments, 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, and the main shaft 6 can be driven to rotate by the protruding structure on the outside of the driven plates, or the main shaft 6 can be indirectly driven to rotate by a transmission mechanism, for example, the transmission mechanism is driven by two incomplete gears, or the transmission mechanism is driven by a connecting rod and a slide groove, etc.

[0070] Specifically, such as Figure 10a-Figure 11 As shown, the structures of the first driven plate 121 and the second driven plate 221 of this embodiment are similar, and both are provided with a driven plate rotation hole 1212. A protruding structure is provided in the driven plate rotation hole 1212 as a driven plate driving portion 1213. The main shaft 6 is provided with a main shaft linkage portion 61 that cooperates with the driven plate driving portion 1213. The main shaft 6 is provided with an arc side wall for rotating the driven plate rotation hole 1212, and a main shaft avoidance notch 62 for avoiding the driven plate driving portion 1213. The connection between the spindle avoidance notch 62 and the arc side wall 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 avoidance notch 62. When the driven plate driving part 1213 rotates to the connection between the spindle avoidance notch 62 and the arc side wall, 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, which are arranged in sequence. The cross-section of the spindle mounting section 64 includes alternating arcuate sidewalls and planar sidewalls. The arcuate sidewalls are used for the rotation of the driven plate, and the gap formed in the planar sidewall serves as the spindle avoidance gap 62. The connection between the spindle avoidance gap 62 and the arcuate sidewalls constitutes the spindle linkage portion 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 in shape, including two opposing arcuate sidewalls and two opposing planar sidewalls. The corresponding driven plates are also provided with two driven plate driving portions 1213. The first connecting section 63 and the second connecting section 65 of the main shaft correspond to the first side plate 103 and the second side plate 104 respectively. The main shaft mounting section 64 is located between the first side plate 103 and the second side plate 104 and is used to mount the first and second driven plates 121 and 221 and the flip member 3. The main shaft output section 66 is used to connect to the switch contact system. The baffle mounting groove 67 is also provided on the second connecting section 65 of the main shaft for mounting the baffle 54 ( Figure 12Obviously, as other embodiments, the cross-sections of the first spindle connecting section 63, the second spindle connecting section 65, and the spindle output section 66 may also be other shapes, such as rectangles, polygons, etc.

[0072] It should be noted that one or more driven plate driving portions 1213 may be provided within the driven plate rotation hole 1212, and the corresponding number of spindle avoidance notches 62 may also be one or more. Furthermore, as another embodiment, the spindle avoidance notches 62 are groove structures formed on the arcuate sidewalls of the spindle, the driven plate driving portions 1213 extend into the groove structures, and the sidewalls on both sides of the groove structures serve as the spindle linkage portions 61. As another embodiment, the driven plate driving portions 1213 are groove structures within the driven plate rotation hole 1212, and the spindle linkage portions 61 are protrusions protruding radially from the spindle 6. The protrusions on the spindle 6 extend into the groove structures of the driven plate rotation hole 1212, allowing the driven plate to rotate around the arcuate sidewalls of the spindle 6 within the region corresponding to the groove structures and the protrusions. When the sidewalls of the groove structures contact the protrusions of the spindle 6, the driven plate and the spindle 6 are contact-limited.

[0073] The operating mechanism of this embodiment is the operating mechanism of a three-position switch. The flip member 3 is rotatably arranged and can be moved to the first position of the flip member, the middle position of the flip member and the second position of the flip member. The first position of the flip member and the second position of the flip member are symmetrically arranged on both sides of the middle position of the flip member. The main shaft 6 can rotate between the main power closing position, the double open position and the backup power closing position. When the flip member 3 is in the middle position of the flip member, the main shaft 6 is in the double open position. When the flip member is in the first position of the flip member, the main shaft 6 is in the main power closing position. When the flip member is in the second position of the flip member, the main shaft 6 is in the backup power closing position.

[0074] When the flip member 3 rotates from the middle position of the flip member to the first position of the flip member, or from the first position of the flip member to the middle position of the flip member, the first connecting rod mechanism 12 is driven to drive the first energy storage spring 11 to first store energy and then release energy after crossing the equilibrium position (dead point position). The first energy storage spring 11 releases energy and drives the first connecting rod mechanism 12 to drive the main shaft 6 to rotate to the corresponding main power closing position or double-open position; when the flip member 3 rotates from the middle position of the flip member to the second position of the flip member, or from the second position of the flip member to the middle position of the flip member, the second connecting rod mechanism 22 is driven to drive the second energy storage spring 21 to first store energy and then release energy after crossing the equilibrium position (dead point position). The second energy storage spring 21 releases energy and drives the second connecting rod mechanism 22 to drive the main shaft 6 to rotate to the corresponding backup power closing position or double-open position.

[0075] The specific action 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 flip member 3 rotates from the middle position of the flip member to the first position of the flip member, or from the first position of the flip member to the middle position of the flip member, the first connecting rod shaft 123 is basically located at one end side wall of the first arc slot 31, and the flip member 3 drives the first connecting rod shaft 123 through the end side wall of the first arc slot 31, thereby driving the first driven plate 121 and the first pulling plate 122 to move. The first pulling plate 122 is forced to pull the first energy storage spring 11 to store energy. When the first energy storage spring 11 is in a balanced position, the energy storage is completed, wherein the balanced position is as shown in FIG. Figure 3b and Figure 5b As shown, the rotation axis of the first energy storage spring 11, the first driven plate 121 and the force direction of the first connecting rod shaft 123 are on the same straight line, and the forces are balanced. The forces of the first energy storage spring 11 and the first connecting rod shaft 123 are offset, and the flip member 3 continues to rotate counterclockwise (as shown in FIG. Figure 3b ) or the flip member 3 continues to rotate clockwise (as Figure 5b ) drives the first driven plate 121 and the first pulling plate 122 to drive the first energy storage spring 11 to slightly pass the equilibrium position, and the flip member 3 reaches the first position of the flip member or the middle position of the flip member, and the driven plate driving part 1213 contacts the main shaft linkage part 61 to limit, and the energy of the first energy storage spring 11 is released, and 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, and the first driven plate 121 drives the main shaft 6 to rotate to the corresponding main power closing position or double opening position through the driven plate driving part 1213, thereby 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 the side wall of one end of the first circular arc slot 31 to the other end of the first circular arc slot 31, and the flip member 3 does not rotate. During this process, the second connecting rod shaft 223 of the second connecting rod mechanism 22 slides in the second arcuate groove 32 of the flip member 3, sliding from one sidewall of the second arcuate groove 32 to the other sidewall, and the second connecting rod mechanism 22 does not move. The driven plate driving portion 1213 of the first driven plate 121 and the main shaft linkage portion 61 of the main shaft 6 can contact 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 flip member 3 rotates from the middle position to the second position, or vice versa, the flip member 3 drives the second link mechanism 22 via the second arcuate slot 32 and the second connecting rod shaft 223. The operation process is similar to that of the first link mechanism 12 and the first energy storage spring 11 described above and will not be repeated here. During this process, the first connecting rod shaft 123 of the first connecting rod mechanism 12 slides in the first arcuate slot 31 of the flip member 3, and the first connecting rod mechanism 12 does not operate.

[0077] Preferably, the operating mechanism is provided with a first connecting rod limiting portion 1025 and a second connecting rod limiting portion, respectively used to limit the rotational position of the activated plate after the first and second energy storage mechanisms 1 and 2 release energy, thereby accurately and reliably limiting the rotational position of the main shaft 6. In this embodiment, the first and second connecting rod limiting portions 1025 and 1026 are disposed on the bracket 102. Of course, in other embodiments, the first and second connecting rod limiting portions 1025 and 1027 may not be provided, and the rotational position of the first and second activated plates 121 and 221 may be limited solely by the sidewalls at both ends of the first and second circular arc grooves 31 and 32 of the flip member 3.

[0078] like Figure 10a 、 10b As shown, a preferred embodiment of the first and second linkage mechanisms 12 and 22 has the same structure, and both include respective driven plates and pulling plates. The structures of the driven plates and pulling plates of the first linkage mechanism 12 are 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 portion, a driven plate rotating hole 1212 is provided in the middle of the driven plate rotating portion, and a driven plate connecting portion is provided on the radially outer side of the driven plate rotating portion. The driven plate connecting portion is hinged to one end of the first pulling plate 122 via a first link shaft 123. A protruding structure is provided within the driven plate rotating hole 1212 as a driven plate driving portion 1213. The driven plate rotating portion also has a driven plate limiting portion 1216 protruding on the radially outer side thereof, which is used to cooperate with the first and second link limiting portions 1025 and 1026 on the bracket 102. The driven plate limiting portion 1216 and the driven plate connecting portion are respectively located on either side of the driven plate rotating portion. The first pulling plate 122 is a plate-shaped 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 formed between the first and second ends of the first pulling plate 122. In this embodiment, the bend creates a V- or U-shaped structure for the first pulling plate 122. This structure helps avoid the spindle 5 during the rotation of the first linkage 12, reduces the rotational distance between the first driven plate 121 and the first pulling plate 122, and reduces the space occupied. In other embodiments, the first pulling plate 122 may also be a straight structure, have other shapes, or have multiple bends.

[0079] like Figure 2b As shown, the first energy storage mechanism 1 and the second energy storage mechanism 2 are arranged symmetrically, and the axis of symmetry is as shown in FIG. Figure 2b A vertical line is drawn in the vertical direction through the rotation axis of the flip member 3 or the main shaft 6, that is, through the rotation axis of the first driven plate 121. The symmetry axis is perpendicular to the axial direction of the main shaft 6 and passes through the rotation axis of the flip member 3. The first energy storage spring 11 and the second energy storage spring 21 are respectively located on both sides of the symmetry axis. The two ends of the first pulling plate 122 are also respectively located on both sides of the symmetry axis. The two ends of the second pulling plate 222 are also respectively located on both sides of the symmetry axis. The first energy storage spring fixed axis 1023, the first end of the first energy storage spring 11 and the first pulling plate 122, and the second end of the second pulling plate 222 are located on one side of the symmetry axis ( Figure 2b The second energy storage spring fixing shaft 1024, the second energy storage spring 21 and the first end of the second pulling plate 222, and the second end of the first pulling plate 122 are located on the other side of the symmetry axis ( Figure 2b right).

[0080] Preferably, the driven plates of the first and second linkage mechanisms 12 and 22 include two driven plates 1214 spaced apart from each other. The pulling plate can be rotated between the two driven plates 1214. The two driven plates 1214 are connected by a plurality of driven plate fixing shafts. The second ends of the pulling plates of the first and second linkage mechanisms 12 and 22 extend between the two driven plates 1214. The connecting rod shaft passes through the two driven plates 1214 and the second ends of the pulling plates to hinge the driven plates to the pulling plates, and both the driven plates and the pulling plates can rotate about the connecting rod shaft. Preferably, a pulling plate limiting shaft 1215 is further provided between the two driven plates 1214 to limit the rotation angle of the pulling plate. Preferably, a limiting plate driving portion 1211 is further provided between the two driven plates 1214. The pulling plate limiting shaft 1215 and the limiting plate driving portion 1211 also serve as the driven plate fixing shafts between the two driven plates 1214.

[0081] Another improvement of the present application is that the operating mechanism also includes a toggle member 4, which can be used as part of a manual operating mechanism, and / or part of an automatic operating mechanism, and / or used to cooperate in locking the position of the flip member 3 and the main shaft 6.

[0082] The toggle member 4 is used as a manual operating mechanism to illustrate the cooperation structure of the toggle member 4 and the flip member 3. The manual operating mechanism of this embodiment includes a toggle member 4, which is drivingly connected to the flip member 3 and is used to drive the flip 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 toggle member 4 is rotatably arranged, the flip member 3 is provided with a first linkage portion 34, and the toggle member 4 is provided with a second linkage portion 41. The toggle member 4 is linked to the flip member 3 through the second linkage portion 41; the toggle member 4 can be rotated to the toggle member first position, the toggle member middle position, and the toggle member second position, and the toggle member first position and the toggle member second position are symmetrically arranged on both sides of the toggle member middle position; when the toggle member 4 rotates to the toggle member first position, the toggle member middle position, and the toggle member second position, it drives the flip member 3 to rotate to the flip member first position, the flip member middle position, and the flip member second position respectively, and drives the first energy storage mechanism 1 or the second energy storage mechanism 2 to drive the main shaft 6 to rotate. Preferably, when the flip member 3 rotates to the flip member first position, the flip member middle position, and the flip member second position, it drives the toggle member 4 to rotate to the toggle member first position, the toggle member middle position, and the toggle member second position respectively, so that the toggle member 4 can play the role of indicating the state of the flip member 3. Preferably, the toggle member 4 is used to drive an indicator mechanism to indicate the state of the operating mechanism. Obviously, as other embodiments, the rotation of the toggle member 4 unidirectionally drives the flip member 3 to rotate, while the rotation of the flip member 3 does not drive the toggle member 4. This is also possible and falls within the scope of protection of this application.

[0083] In this embodiment, Figure 9 and Figure 13 As shown, the first linkage portion 34 and the second linkage portion 41 are gears, and the flip member 3 and the toggle member 4 are linked by gear engagement. Obviously, as other embodiments, the flip member 3 and the toggle member 4 can also be driven and connected by means of a hinge, a drive rod and a drive groove, etc. For example, a drive groove can be provided on the flip member 3, and the toggle member 4 can be provided with a drive rod that cooperates with it. The drive rod is inserted into the drive groove and pushes on the side walls of the drive groove, thereby driving the flip member 3 to rotate in both directions. In addition, the toggle member 4 can also indirectly drive the flip member 3 through a transmission mechanism such as a connecting rod or a lever; all of these fall within the scope of protection of this application.

[0084] like Figure 8 and Figure 13As shown, the toggle member 4 is provided with a toggle member driving portion 45 for manual operation, which is used to drive the toggle member 4 to rotate. In this embodiment, the toggle member driving portion 45 is a hole-shaped structure, which drives the toggle member 4 to rotate by inserting a drive rod. Obviously, as other embodiments, the toggle member driving portion 45 can also be a raised handle, which extends outside the housing of the operating mechanism, and drives the toggle member 4 to rotate by directly operating the handle. In addition, the manual operating mechanism can also include other transmission mechanisms, which can indirectly drive the toggle member 4 to rotate. If the toggle member 4 is driven by an electric mechanism, the toggle member 4 can be used as part of the automatic operating mechanism and is not used for the manual operating mechanism. For example, the automatic operating mechanism includes a first electromagnetic mechanism 7 and a second electromagnetic mechanism 8, each of which includes an electromagnetic component and a moving rod 782 connected to the electromagnetic component. When the electromagnetic component is energized, the moving rod 782 drives the toggle member 4 to rotate. Alternatively, the automatic operating mechanism includes a motor and a gear set connected to the motor. The motor drives the toggle member 4 to rotate through the gear set. An incomplete gear transmission can be used between the gear set and the toggle member 4.

[0085] It should be noted that the manual operating mechanism may not use the rotating toggle member 4, but may use other means such as a sliding push rod to cooperate with the flip member 3 in driving.

[0086] Another improvement of the present application is that a spindle locking mechanism 5 is provided for locking the spindle 6 in the main power closing position or the backup power closing position. When the flip member 3 rotates to the first position of the flip 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 flip member 3 rotates to the middle position of the flip member, the spindle locking mechanism 5 is driven to release the lock on the spindle 6. When the flip member rotates to the second position, the spindle locking mechanism 5 is driven to lock the spindle 6, so that the spindle 6 cannot rotate to the double-split position, thereby avoiding 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 of this embodiment includes a first lever 51 and a second lever 52, the first lever 51 is provided with a first lever locking portion 512, the second lever 52 is provided with a second lever locking portion 522, and the spindle 6 is provided with a first locking portion 541 and a second locking portion 542; when the flip member 3 moves to the first position of the flip member, it avoids the first lever 51, so that the first elastic member 53 drives the first lever 51 to drive the first lever locking portion 512 to move in the direction close to the spindle 6, and when the spindle 6 rotates to the main power closing position, the first locking portion 541 of the spindle 6 is locked with the first lever locking portion 512 so that the spindle 6 cannot rotate to the double-split position, thereby locking the spindle 6 in the main power closing position; when the flip member 3 moves to the second position of the flip member, it avoids the second lever 52, so that the second elastic member drives the second lever 52 to drive the first The second lever locking portion 522 moves in the direction close to the main shaft 6, and when the main shaft 6 rotates to the backup power closing position, the second locking portion 542 of the main shaft 6 is locked with the second lever locking portion 522, so that the main shaft 6 cannot rotate to the double-split position, and the main shaft 6 is locked in the backup power closing position; when the flip member 3 rotates from the first position of the flip member to the middle position of the flip member, the first lever 51 is driven to overcome the force of the first elastic member 53 to drive the first lever locking portion 512 to move in the direction away from the main shaft 6, and the locking cooperation with the first locking portion 541 of the main shaft 6 is released; when the flip member 3 rotates from the second position of the flip member to the middle position of the flip member, the second lever 52 is driven to overcome the force of the second elastic member to drive the second lever locking portion 522 to move in the direction away from the main shaft 6, and the locking cooperation with the second locking portion 542 of the main shaft 6 is released.

[0088] like Figure 2c 、 Figure 4c 、 Figure 5c 、 Figure 7b A preferred embodiment is shown, in which the first elastic member 53 also serves as the second elastic member, that is, the first elastic member 53 and the second elastic member are the same elastic member, and the first elastic member 53 is connected between the first lever 51 and the second lever 52. Only one first elastic member 53 needs to be provided to simplify the structure.

[0089] In this embodiment, the spindle locking mechanism 5 further includes a baffle 54, which is fixedly mounted on the spindle 6, and a first locking portion 541 and a second locking portion 542 are mounted on the baffle 54. Figure 12 In this embodiment, a baffle mounting hole 543 is provided in the middle of the baffle 54. 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, that is, the first locking portion 541 and the second locking portion 542 are directly provided on the main shaft 6.

[0090] In this embodiment, the flip member 3 drives the spindle locking mechanism 5 via the toggle member 4. When the flip member 3 rotates to the first flip position, the middle flip position, and the second flip position, the toggle member 4 correspondingly rotates to the first toggle position, the middle toggle position, and the second toggle position, respectively. When the toggle member 4 rotates to the first toggle position and the second toggle position, the spindle locking mechanism 5 is driven to lock the spindle 6, preventing the spindle 6 from rotating to the double-split position. When the toggle member 4 rotates to the middle toggle position, the spindle locking mechanism 5 is driven to release the lock on the spindle 6. Of course, the flip member 3 can also directly drive the first lever 51 and the second lever 52, or drive the first lever 51 and the second lever 52 through other transmission structures.

[0091] The toggle member 4 is provided with a third toggle portion 44 for driving the first lever 51 and the second lever 52. The third toggle portion 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 portion 541 and a second locking portion 542. The side of the first lever 51 provided with the first lever locking portion 512 and the side of the second lever 52 provided with the second lever locking portion 522 are spaced apart from each other and are respectively located on both sides of the main shaft 6.

[0092] When the toggle member 4 moves to the first toggle position, it drives the second lever 52 to move away from the main shaft 6 and avoid the first lever 51, so that the first elastic member 53 drives the first lever 51 to drive the first lever locking portion 512 to move toward the main shaft 6. When the main shaft 6 rotates to the main power on position, the first locking portion 541 of the main shaft 6 is locked with the first lever locking portion 512, so that the main shaft 6 cannot rotate to the double open position.

[0093] When the toggle member 4 moves to the second position, it drives the first lever 51 to move away from the main shaft 6 and avoid the second lever 52, so that the first elastic member 53 drives the second lever 52 to drive the second lever locking portion 522 to move towards the main shaft 6. When the main shaft 6 rotates to the backup power on position, the second locking portion 542 of the main shaft 6 is locked with the second lever locking portion 522, so that the main shaft 6 cannot rotate to the double open position.

[0094] When the toggle member 4 rotates from the first position of the toggle member to the middle position of the toggle member, the first lever 51 is driven to overcome the force of the first elastic member 53 and drive the first lever locking portion 512 to move away from the main shaft 6, thereby releasing the locking cooperation with the first locking portion 541 of the main shaft 6, and the first elastic member 53 drives the second lever 52 to reset; when the toggle member 4 rotates from the second position of the toggle member to the middle position of the toggle member, the second lever 52 is driven to overcome the force of the first elastic member 53 and drive the second lever locking portion 522 to move away from the main shaft 6, thereby releasing the locking cooperation with the second locking portion 542 of the main shaft 6, and the first elastic member 53 drives the first lever 51 to reset.

[0095] Another improvement of the present application is that the operating mechanism is also 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 of the toggle member, and / or the second position of the toggle member, and / or the middle position of the toggle member, thereby limiting the flip member 3 to the corresponding position, 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 provided on the bracket 102, the first limiting shaft 1021 and the second limiting shaft 1022 are fixedly provided between the first side plate 103 and the second side plate 104. Figure 3b When the toggle member is rotated clockwise to the first position as shown in FIG. 1 , it is limited by the first limiting shaft 1021 and cannot continue to rotate clockwise. Figure 7b When the toggle member rotates counterclockwise to the second position, it is limited by the second limiting shaft 1022 and cannot continue to rotate counterclockwise. As another embodiment, the second side plate sliding groove 1041 on the bracket 102 and the third toggle portion 44 on the toggle member 4 can cooperate to achieve the toggle member 4 being limited to the first position and the second position ( Figure 4c ).in, Figure 15 A schematic structural diagram 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 to drive 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 to drive the second limiting plate 92 to move away from the toggle member 4 to avoid the toggle member 4.

[0098] When the flip member 3 rotates from the first position of the flip member to the middle position of the flip member, the toggle member 4 rotates from the first position of the toggle member to the middle position of the toggle member, the flip member 3 drives the first energy storage mechanism 1 to store energy first and cross the equilibrium position, and the first energy storage mechanism 1 drives the first limit plate 91 to move in the direction close to the toggle member 4, and the limit plate limit portion 9120 of the first limit plate 91 limits the toggle member 4 in 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 ( Figure 5b ), the first energy storage mechanism 1 that has passed the equilibrium position releases energy to drive the main shaft 6 to rotate to the double-split position, and the first energy storage mechanism 1 avoids the first limit plate 91, and the first limit plate reset member 93 drives the first limit plate 91 to move and release the limit on the toggle member 4 ( Figure 2a ), the toggle member 4 can be subsequently operated to rotate toward the second position or the first position;

[0099] Similarly, when the flip member 3 rotates from the second position of the flip member to the middle position of the flip member, the toggle member 4 rotates from the second position of the toggle member to the middle position of the toggle member, and the flip member 3 drives the second energy storage mechanism 2 to store energy first and cross the equilibrium position. The second energy storage mechanism 2 drives the second limit plate 92 to move in the direction close to the toggle member 4, and the limit plate limit portion 9120 of the second limit plate 92 limits the toggle member 4 in the middle position of the toggle member, so that the toggle member 4 cannot continue to rotate toward the first position of the toggle member. The second energy storage mechanism 2 that has crossed the equilibrium position releases energy to drive the main shaft 6 to rotate to the double-split position, and the second energy storage mechanism 2 avoids the second limit plate 92 ( Figure 2a ), the second limit plate reset member 94 drives the second limit plate 92 to move to release the limit on the toggle member 4, and then the toggle member 4 can be operated to rotate to the second position of the toggle member or the first position of the toggle member.

[0100] The operating mechanism of this embodiment is provided with a toggle member limiting mechanism 9, which drives the toggle member limiting mechanism 9 to limit the toggle member 4 to the middle position of the toggle member and also to limit the flip member 3 to the middle position of the flip member 3 through the action of the first energy storage mechanism 1 and the second energy storage mechanism 2 when the energy storage reaches the equilibrium position. After that, the toggle member limiting mechanism 9 is avoided by the energy release action of the first energy storage mechanism 1 and the second energy storage mechanism 2, and the limit on the toggle member 4 is released, so that it can move to the first position of the toggle member and the second position of the toggle member, thereby improving the reliability and safety of the operation of the operating mechanism.

[0101] In this embodiment, the first energy storage mechanism 1 and the second energy storage mechanism 2 each include a connecting rod mechanism and an energy storage spring. The connecting rod mechanisms of the first energy storage mechanism 1 and the second energy storage mechanism 2 are respectively a first connecting rod mechanism 12 and a second connecting rod mechanism 22. The energy storage springs of the first energy storage mechanism 1 and the second energy storage mechanism 2 are respectively a first energy storage spring 11 and a second energy storage spring 21. The first energy storage mechanism 1 cooperates with the first limit plate 91 through the first connecting rod mechanism 12 to drive the first limit plate 91 to move toward the direction close to the toggle member 4 or avoid the first limit plate 91. The second energy storage mechanism 2 cooperates with the second limit plate 92 through the second connecting rod mechanism 22 to drive the second limit plate 92 to move toward the direction close to the toggle member 4 or avoid the second limit plate 92.

[0102] When the toggle member 4 moves from the first position of the toggle member to the middle position of the toggle member, the first connecting rod mechanism 12 rotates to drive the first energy storage spring 11 to store energy and cross the equilibrium position, and the first connecting rod mechanism 12 drives the first limit plate 91 to overcome the force of the first limit plate reset member 93 and move in the direction close to the toggle member 4, so that the limit plate limit portion 9120 is located on the moving trajectory of the toggle member 4, and the toggle member 4 is positioned in the middle position of the toggle member. After the first connecting rod mechanism 12 crosses the equilibrium position, the first energy storage spring 11 releases energy to drive the first connecting rod mechanism 12 to continue rotating, and the first connecting rod mechanism 12 avoids the first limit plate 91, and the first limit plate reset member 93 drives the first limit plate 91 to make the limit plate limit portion 9120 avoid the toggle member 4, so that the toggle member 4 can rotate to the first position of the toggle member and the second position of the toggle member. When the toggle member 4 moves from the second position of the toggle member to the middle position of the toggle member, the second connecting rod mechanism 22 rotates to drive the second energy storage spring 21 to store energy and cross the equilibrium position, and the second connecting rod mechanism 22 drives the second limit plate 92 to overcome the force of the second limit plate reset member 94 and move in the direction close to the toggle member 4, so that the limit plate limit portion 9120 is located on the moving trajectory of the toggle member 4 and positions the toggle member 4 in the middle position of the toggle member. After the second connecting rod mechanism 22 crosses the equilibrium position, the second energy storage spring 21 releases energy to drive the second connecting rod mechanism 22 to continue to rotate, and the second connecting rod mechanism 22 avoids the second limit plate 92, and the second limit plate reset member 94 drives the second limit plate 92 to make the limit plate limit portion 9120 avoid the toggle member 4, so that the toggle member 4 can rotate to the first position of the toggle member and the second position of the toggle member.

[0103] Specifically, refer to Figure 2a 、 Figure 14The first limit plate 91 and the second limit plate 92 have the same structure and are plate-shaped structures. The first ends of the first limit plate 91 and the second limit plate 92 are provided with limit plate rotation holes 9124, which can be rotatably installed on the bracket 102, and the second ends are provided with limit plate sliding grooves 9122. The limit plate sliding grooves 9122 are sleeved on the limit plate limit shaft of the bracket 102 to limit the rotation angle of the first limit plate 91 and the second limit plate 92; one end of the first limit plate reset member 93 and the second limit plate reset member 94 are respectively connected to the second ends of the first limit plate 91 and the second limit plate 92, and the other end is connected to the bracket 102, driving the first limit plate 91 and the second limit plate 92 to rotate in the direction away from the toggle member 4. Obviously, as other embodiments, the limit plate sliding groove 9122 may not be provided, and a limit protrusion may be provided on the bracket 102 to limit the rotation angle of the first limit plate 91 and the second limit plate 92; the first limit plate reset member 93 and the second limit plate reset member 94 may also not use tension springs, but may also be other elastic members such as torsion springs and springs.

[0104] The first limiting plate 91 and the second limiting plate 92 are provided with a toggle member slot 9121 on the side facing the toggle member 4, which is used to cooperate with the first toggle part 42 and the second toggle part 43 of the toggle member 4. One side wall of the toggle member slot 9121 serves as the limiting plate limiting part 9120, which is used to limit the toggle member 4 to the middle position of the toggle member; the first limiting plate 91 and the second limiting plate 92 are provided with a limiting plate driving surface 9123 on the side away from the toggle member 4, that is, on the side facing the connecting rod mechanism, which is used to cooperate with the limiting plate driving part 1211 on the corresponding driven plate of the connecting rod mechanism (such as Figure 10b ), the first energy storage mechanism 1 and the second energy storage mechanism 2 drive the corresponding first and second limit plates 91 and 92 to rotate toward the toggle member 4 via the limit plate driving surface 9123. Preferably, the limit plate driving surface 9123 is an arc surface, and the toggle member slot 9121 is an arc-shaped slot. Of course, in other embodiments, the toggle member slot 9121 may be omitted, and a protrusion may be directly provided as the limit plate limit portion 9120.

[0105] See also Figure 2a 、 Figure 10a and Figure 10b The first link mechanism 12 and the second link mechanism 22 each include a pulling plate and a receiving plate. The pulling plate and the receiving plate of the first link mechanism 12 are respectively a first receiving plate 121 and a first pulling plate 122. The pulling plate and the receiving plate of the second link mechanism 22 are respectively a second receiving plate 221 and a second pulling plate 222. The first receiving plate 121 and the second receiving plate 221 are both provided with a limit plate driving portion 1211. The first link mechanism 12 and the second link mechanism 22 drive the limit plate driving surface 9123 (such as Figure 14) The first limit plate 91 and the second limit plate 92 are rotated in the direction close to the toggle member 4, so that the first toggle part 42 of the toggle member 4 enters the toggle member slot 9121 of the first limit plate 91 or the second toggle part 43 of the toggle member 4 enters the toggle member slot 9121 of the second limit plate 92. When the toggle member 4 rotates to the middle position of the toggle member, the first toggle part 42 slides and is limited by the limit plate limit part 9120 of the first limit plate 91, or the second toggle part 43 slides and is limited by the limit plate limit part 9120 of the second limit plate 92. It should be noted that the first link mechanism 12 and the second link mechanism 22 are not limited to the pulling plate and the driven plate, and can also include other linked links, or can also be a structure that does not use the pulling plate and the driven plate, such as the technical solution in the prior art mentioned in the background technology.

[0106] See also Figure 10a 、 10b The first activated plate 121 and the second activated plate 221 both include two activated plates 1214 that are relatively spaced apart. The two activated plates 1214 are connected by a plurality of activated plate fixed shafts. A limit plate driving portion 1211 is also provided between the two activated plates 1214. At least a portion of the first limit plate 91 (such as the limit plate driving surface 9123) extends between the two activated plates 1214 of the first activated plate 121 and cooperates with the limit plate driving portion 1211. At least a portion of the second limit plate 92 (such as the limit plate driving surface 9123) extends between the two activated plates 1214 of the first activated plate 121 and cooperates with the limit plate driving portion 1211, thereby improving reliability and avoiding misalignment. In this embodiment, the limit plate driving part 1211 is two fixed shafts 1211a and 1211b arranged on the active plate. Of course, the limit plate driving part 1211 can also be an arc-shaped rib or other similar or similar structures. Anything that a person skilled in the art can think of falls within the scope of protection of this application.

[0107] The following describes the process of the toggle member 4 cooperating with the first limit plate 91 with reference to the accompanying drawings. The process of the toggle member 4 cooperating with the second limit plate 91 is similar:

[0108] like Figure 4bAs shown, when the toggle member 4 is in the first position of the toggle member, the axis 1211a of the limit plate driving part 1211 of the first driven plate 121 drives the first limit plate 91 through the limit plate driving surface 9123 to overcome the action of the first limit plate reset member 93 and rotate in the direction close to the toggle member 4, so that the first toggle part 42 of the toggle member 4 is located in the toggle member slot 9121; when the toggle member 4 moves from the first position of the toggle member to the middle position of the toggle member, the flip member 3 moves from the first position of the flip member to the middle position of the flip member, and the flip member 3 drives the first connecting rod 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 limit plate driving portion 1211 keeps driving the first limit plate 91 to rotate toward the toggle member 4 via the limit plate driving surface 9123. The first toggle portion 42 of the toggle member 4 slides in the toggle member slot 9121, and the first toggle portion 42 of the toggle member 4 moves to a position where one end of the toggle member slot 9121 is limited by the side wall of the limit plate limit portion 9120, thereby limiting the toggle member 4 to the middle position of the toggle member and preventing the toggle member 4 from continuing to rotate toward the second toggle position.

[0109] The first energy storage spring 11 that has passed the equilibrium position releases energy to drive the first connecting rod mechanism 12 to continue rotating. The first passive plate 121 rotates and drives the main shaft 6 to rotate to the double-split position. The limit plate driving portion 1211 of the first passive plate 121 is misaligned with the limit plate driving surface 9123 of the first limit plate 91. The first limit plate reset member 93 drives the first limit plate 91 to rotate, releasing the limit on the toggle member 4. Subsequently, the toggle member 4 can be operated to rotate to the second toggle position or the first toggle position.

[0110] like Figure 2a As shown, when the toggle member 4 is located in the middle position of the toggle member, the first limiting plate 91 and the second limiting plate 92 do not limit the toggle member 4, that is, the first toggle part 42 and the second toggle part 43 of the toggle member 4 are respectively located outside the toggle member slot 9121 of the first limiting plate 91 and the second limiting plate 92.

[0111] like Figure 4bAs shown, when the toggle member 4 rotates from the middle position of the toggle member to the first position of the toggle member, the toggle member 4 is limited by the first limit shaft 1021 on the bracket 102, and the flip member 3 rotates and drives the first connecting rod mechanism 12 to rotate to drive the first energy storage spring 11 to store energy and cross the equilibrium position. The first energy storage spring 11 that crosses the equilibrium position drives the first connecting rod mechanism 12, and the limit plate driving part 1211 of the first driven plate 121 of the first connecting rod mechanism 12 drives the first limit plate 91 through the limit plate driving surface 9123 to overcome the force of the first limit plate reset member 93 and rotate in the direction close to the toggle member 4, so that the first toggle part 42 of the toggle member 4 is located in the toggle member slot 9121 near the middle position, and there is a gap between the first toggle part 42 and the limit plate limiting part 9120 of the first limiting plate 91. At this time, the side wall at one end of the toggle member slot 9121 does not limit the toggle member 4.

[0112] The process of the toggle member 4 rotating from the second position of the toggle member to the middle position of the toggle member is similar. When the flip member 3 rotates from the middle position of the flip member to the second position of the flip member, the toggle member 4 rotates from the middle position of the toggle member to the second position of the toggle member, and the flip member 3 drives the second energy storage mechanism 2 to store energy first and cross the equilibrium position. The second energy storage mechanism 2 that crosses the equilibrium position releases energy to drive the main shaft 6 to rotate to the auxiliary power supply closing position, and drives the second limit plate 92 to rotate in the direction close to the toggle member 4, and the second toggle part 43 of the toggle member 4 is located in the toggle member slot 9121 near the middle position, and there is a gap between the second toggle part 43 and the limit plate limit part 9120 of the second limit plate 92.
