Description

Technical Field

[0001] The utility model relates to the field of low-voltage electrical appliances, in particular to an operating mechanism of a transfer switch. Background Art

[0002] As an important support for the development of modern social economy and people's livelihood, the power transmission and distribution line system plays an irreplaceable role. As an important component carrier in the power transmission and distribution line system, the transfer switch plays an important function, especially in hospitals, smart buildings, data centers, power plants, banks, important infrastructure and other occasions that require uninterrupted, reliable, stable and continuous power output.

[0003] In the prior art, transfer switches are mostly of two types: two-position transfer switches and three-position transfer switches. The two-position transfer switch switches between two states: the main power supply is closed (and the backup power supply is opened) and the backup power supply is closed (and the main power supply is opened), achieving continuous, stable, and reliable power output for the transmission and distribution lines. In addition to achieving the working state of the two-position transfer switch, the three-position transfer switch can also achieve the simultaneous opening of the main and backup power supplies (i.e., a dual-open state). For example, the prior art CN111986938A, CN109786146A, CN109686598A, CN113838694A, CN113611553A, etc. all disclose different transfer switches.

[0004] In the prior art, the operating mechanism of the transfer switch has the following problems:

[0005] (1) The automatic operating mechanism uses a motor with a slow transmission speed, or uses an electromagnetic mechanism but requires a complex transmission mechanism.

[0006] (2) The overall layout is unreasonable and occupies a large space.

[0007] (3) The operating mechanism can realize three-position switching, and the switching speed is independent of the speed of the manual operating mechanism and the automatic operating mechanism. 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.

[0008] (4) When the spindle is in the main power on position and the standby power on position, there is no limit structure for the spindle, and it is impossible to prevent other mechanisms outside the operating mechanism from causing the spindle to flip.

[0009] (5) 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. Utility Model Content

[0055] 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.

[0056] 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 both 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 and the backup power supply supplying the load. For a two-position transfer switch, the operating mechanism drives the main shaft 6 to rotate between two positions: the main power closed position and the backup power closed position. When the main shaft 6 rotates to the main power closed position, it switches the switch contact system to the main power connected state. When it rotates to the backup power closed position, it switches the switch contact system to the backup power connected state. 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 switches the switch contact system to the main power connected state, the main power and backup power disconnected state, or the backup power connected state, respectively.

[0057] 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.

[0058] For example, for a two-position switching switch, the flip member 3 can rotate between the first position of the flip member and the second position of the flip member to drive the main shaft 6 to rotate between the main power closing position and the backup power closing position; when the flip member 3 moves from the second position of the flip member to the first position of the flip member, it drives the first energy storage mechanism 1 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 main power closing position; when the flip member 3 moves from the first position of the flip member to the second position of the flip member, it drives the second energy storage mechanism 2 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 backup power closing position.

[0059] For a three-position switching switch, 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 2a As 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, one of the improvements of the present application lies in the transmission structure between the energy storage mechanism and the main shaft 6. The first energy storage mechanism 1 and the second energy storage mechanism 2 each include an activated plate that cooperates with the main shaft 6. The activated plates of the first energy storage mechanism 1 and the second energy storage mechanism 2 are respectively the first activated plate 121 and the second activated plate 221. The activated plate is provided with an activated plate rotation hole 1212, and an activated plate driving portion 1213 is provided in the activated plate rotation hole 1212. The main shaft 6 is provided with a main shaft linkage portion 61. The activated plate is sleeved on the main shaft 6 through the activated plate rotation hole 1212. The activated plate can rotate around the main shaft 6 and after the activated plate driving portion 1213 contacts and limits the main shaft linkage portion 61, the activated plate drives the main shaft 6 to rotate.

[0062] When the flip member 3 rotates to drive the first energy storage mechanism 1 to move toward the equilibrium position, the driven plate driving portion 1213 of the driven plate of the first energy storage mechanism 1 rotates in the direction of contacting and limiting with the main shaft linkage portion 61. After the first energy storage mechanism 1 passes the equilibrium position, the energy is released, driving the driven plate of the first energy storage mechanism 1 to rotate, thereby driving the main shaft 6 to rotate through the driven plate driving portion 1213 contacting and limiting with the main shaft linkage portion 61.

[0063] The flip member 3 rotates to drive the second energy storage mechanism 2 to move toward the equilibrium position, and the driven plate driving part 1213 of the driven plate of the second energy storage mechanism 2 rotates in the direction of contact and limit with the main shaft linkage part 61. After the second energy storage mechanism 2 passes the equilibrium position, it releases energy and drives the driven plate of the second energy storage mechanism 2 to rotate, driving the main shaft 6 to rotate through the driven plate driving part 1213 contacting the limit and the main shaft linkage part 61.

[0064] In this embodiment, the driven plates of the first energy storage mechanism 1 and the second energy storage mechanism 2 are each provided with a driven plate rotation hole 1212, within which a driven plate driving portion 1213 is provided. A main shaft linkage portion 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 is capable of rotating about the main shaft 6. After the driven plate rotates a certain distance until the driven plate driving portion 1213 contacts the main shaft linkage portion 61 to limit the position, the driven plate drives the main shaft 6 to rotate. The operating mechanism of this embodiment directly mounts the driven plates of the first energy storage mechanism 1 and the second energy storage mechanism 2 on the main shaft 6. The driven plates are capable of rotating about the main shaft 6. After the driven plate driving portion 1213 contacts the main shaft linkage portion 61, the driven plate drives the main shaft 6 to rotate. No redundant transmission structure is required, resulting in a simple and compact structure.

[0065] 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. When the flip member 3 drives the second energy storage mechanism 2 to first store energy and then release the energy after crossing the equilibrium position, the driven plate driving portion 1213 of the driven plate of the second energy storage mechanism 2 only contacts and limits the spindle linkage portion 61 when the energy storage spring of the second energy storage mechanism 2 reaches the equilibrium position, or after crossing 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 spindle 6, and the driven plate driving portion 1213 moves in a direction approaching the spindle linkage portion 61. There is no contact and limit between the two, and this process does not drive the spindle 6 to rotate. In this way, the spindle 6 does not move during the energy storage mechanism's energy storage process. After the energy storage mechanism releases the energy, the spindle 6 is driven to rotate rapidly 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. This ensures that the operating mechanism can quickly drive the spindle 6 to switch the power supply, reduces arc burning of the switch contact system, and improves the performance and reliability of the transfer switch.

[0066] The transmission structure between the energy storage mechanism and the main shaft 6 of the present application is described below in conjunction with a specific embodiment of the energy storage mechanism.

[0067] like Figure 2a 、 Figure 2bAs shown, the energy storage mechanism of this embodiment 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 groove 31 and a second circular arc slide groove 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 groove 31 and the second circular arc slide groove 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] like Figure 10a-Figure 11As 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.

[0073] 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 arc sidewalls and flat sidewalls. The arc sidewalls have the same center. The arc sidewalls are used for the rotation of the driven plate. The gap formed in the flat sidewall serves as the spindle avoidance gap 62. The connection between the spindle avoidance gap 62 and the arc sidewall 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 oppositely arranged arc sidewalls and two oppositely arranged flat sidewalls. The two ends of the two arc sidewalls are respectively connected between the two arc sidewalls. Two driven plate driving parts 1213 are also provided on the corresponding driven plate. The first and second spindle connecting sections 63 and 65 correspond to the first and second side plates 103 and 104, respectively. The spindle mounting section 64 is located between the first and second side plates 103 and 104 and is used to mount the first and second driven plates 121 and 221 and the flip member 3. The spindle output section 66 is used to connect to the switch contact system. Obviously, in other embodiments, the cross-sections of the first and second spindle connecting sections 63, 65, and 66 can also have other shapes, such as rectangles or polygons.

[0074] The first and second driven plates 121, 221 are rotatably mounted on the spindle mounting section 64 of the spindle 6 through their respective driven plate rotation holes 1212. The flip member 3 is rotatably mounted on the spindle 6 through the circular flip member rotation hole 33 and is located between the first and second driven plates 121, 221. The flip member 3 is capable of rotating about the spindle 6. The first and second driven plates 121, 221 are also capable of rotating about the spindle 6. When the driven plate driving portions 1213 in the driven plate rotation holes 1212 come into contact with the spindle linkage portion 61, the flip member 3 drives the spindle 6 to rotate.

[0075] The flip member 3 drives the first connecting rod shaft 123 through the first circular arc slot 31, driving the first driven plate 121 and the first pulling plate 122 to rotate, so that the first energy storage spring 11 stores energy first. At this time, the driven plate driving part 1213 corresponds to the main shaft avoidance gap 62, and does not drive the main shaft 6 to rotate. After the first energy storage spring 11 passes the equilibrium position (or when the first energy storage spring 11 is in the equilibrium position), the driven plate driving part 1213 of the first driven plate 121 contacts the main shaft linkage part 61 to limit the position, and the first energy storage spring 11 releases energy through the first pulling plate 122 to drive the first driven plate 121 to rotate, and the first driven plate 121 drives the main shaft 6 to rotate. The flip member 3 drives the second connecting rod shaft 223 through the second circular 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 (or when the second energy storage spring 21 is in the equilibrium position), the driven plate driving part 1213 of the second driven plate 221 contacts and limits the main shaft linkage part 61, and the second energy storage spring 21 releases energy to drive the second driven plate 221 to rotate through the second pulling plate 222. After the driven plate driving part 1213 contacts and limits the main shaft linkage part 61, the second driven plate 221 drives the main shaft 6 to rotate.

[0076] 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.

[0077] It should be noted that the structures of the first energy storage mechanism 1 and the second energy storage mechanism 2 of the present application are not limited to the above embodiments. Any of the prior art energy storage mechanisms listed in the background art can be used. It is only necessary to rotatably mount the drive member that drives the main shaft 6 of the energy storage mechanism on the main shaft 6. The drive member can rotate freely during the energy storage phase and drive the main shaft 6 during the energy storage mechanism release phase. The first and second link mechanisms 12 and 22 are also not limited to a pulling plate and a driven plate, and can also include other linked links.

[0078] 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.

[0079] 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.

[0080] It should be noted that, as other embodiments, the operating mechanism of this embodiment can also be used for a two-position switch, such as adjusting the position and length of the first circular arc slot 31 and the second circular arc slot 32, so that the flip member 3 can be rotated to the first flip member position and the second flip member position, and the main shaft 6 can rotate between the main power closing position and the backup power closing position; when the flip member 3 moves from the second flip member position to the first flip member position, 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; when the flip member 3 moves from the first flip member position to the second flip member position, 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.

[0081] The specific action process of the energy storage mechanism in this embodiment is as follows: Figure 2b 、 Figure 3a 、 Figure 3b 、 Figure 4a 、 Figure 4b 、 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.

[0082] like Figure 2b 、 Figure 6 、 Figure 7 and Figure 8 As 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.

[0083] Preferably, the operating mechanism is provided with a first connecting rod limiting portion 1025 and a second connecting rod limiting portion, which are respectively used to limit the rotation 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 rotation position of the main shaft 6. In this embodiment, the first connecting rod limiting portion 1025 and the second connecting rod limiting portion are arranged on the bracket 102, such as Figure 13As shown, in this embodiment, two first connecting rod limiting portions 1025 are provided on the first side plate 103, respectively used to limit the rotational position of the first activated plate 121 after the first energy storage mechanism 1 releases energy when the flip member 3 rotates to the first flip member position and the flip member intermediate position; correspondingly, two second connecting rod limiting portions are also provided on the second side plate 104, respectively used to limit the rotational position of the second activated plate 221 after the second energy storage mechanism 2 releases energy when the flip member 3 rotates to the second flip member position and the flip member intermediate position. Of course, in other embodiments, the first connecting rod limiting portions 1025 and the second connecting rod limiting portions may be omitted, and the rotational position of the first activated plate 121 and the second activated plate 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.

[0084] like Figure 10a 、 10b As shown, a preferred embodiment of the first link mechanism 12 and the second link mechanism 22 has the same structure and both include respective driven plates and pulling plates. The structures of the driven plates and pulling plates are explained below by taking the driven plates and pulling plates of the first link mechanism 12, i.e., the first driven plate 121 and the first pulling plate 122 as examples. The first driven plate 121 includes a driven plate rotating portion, a driven plate rotating hole 1212 disposed in the middle of the driven plate rotating portion, and a driven plate connecting portion protruding radially outward from the driven plate rotating portion. The driven plate connecting portion is hingedly connected to one end of the first pulling plate 122 via a first connecting rod shaft 123. A protruding structure serving as a driven plate driving portion 1213 is disposed within the driven plate rotating hole 1212. A driven plate limiting portion 1216 is also protruded radially outward from the driven plate rotating portion, configured to engage with the first connecting rod limiting portion 1025 and the second connecting rod limiting portion on the bracket 102. The driven plate limiting portion 1216 and the driven plate connecting portion are located on either side of the driven plate rotating portion, respectively. The first pulling plate 122 is a plate-shaped structure, with a first end connected to the first energy storage spring 11 and a second end 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 bends give the first pulling plate 122 a V-shaped or U-shaped structure. This structure helps avoid the main shaft 5 during the rotation of the first linkage mechanism 12, shortens the rotation 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 can also be a straight structure or other shapes, or have multiple bends.

[0085] 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 2bA 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).

[0086] 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 and the pulling plates together. 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. The pulling plate limiting shaft 1215 also serves as the driven plate fixing shaft between the two driven plates 1214.

[0087] The operating mechanism also includes a toggle 4, which can be used as a part of a manual operating mechanism and / or a part of an automatic operating mechanism. The toggle 4 is now used as a manual operating mechanism to illustrate the coordination structure of the toggle 4 and the flip member 3. The manual operating mechanism of this embodiment includes a toggle 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 12As 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. 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, which is also possible and falls within the protection scope of this application.

[0088] In this embodiment, Figure 9 and Figure 12 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.

[0089] like Figure 12As 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.

[0090] like Figure 1 、 Figure 2a As shown, the layout of the operating mechanism of this embodiment, the bracket 102 includes a first side plate 103 and a second side plate 104, the first energy storage mechanism 1, the second energy storage mechanism 2 and the flip member 3 are arranged between the first side plate 103 and the second side plate 104, the flip member 3 is rotatably arranged on the main shaft 6, the first electromagnetic mechanism 7 and the second electromagnetic mechanism 8 are symmetrically arranged on both sides below the flip member 3, and the toggle member 4 is located above the flip member 3. The operating mechanism of this embodiment is provided with an energy storage mechanism, a manual operating mechanism and an automatic operating mechanism. The energy storage mechanism includes the first energy storage mechanism 1, the second energy storage mechanism 2 and the flip member 3. The flip member 3 is used to drive the first energy storage mechanism 1 and the second energy storage mechanism 2 to first store energy and then release energy to drive the main shaft 6 to rotate after crossing the equilibrium position. The flip member 3 does not rotate with the main shaft 6 but is rotatably arranged 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 toggle member 4.

[0091] The first side plate 103 and the second side plate 104 are connected by several fixed shafts, including a first energy storage spring fixed shaft 1023, a second energy storage spring fixed shaft 1024, a first limiting shaft 1021, a second limiting shaft 1022, and a toggle member installation 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 respectively rotatably connected to the first energy storage spring fixed shaft 1023 and the second energy storage spring fixed shaft 1024; the toggle member 4 is rotatably mounted on the toggle member installation shaft 1026, and the 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 spindle hole through which the main shaft 6 passes.

[0092] Preferably, the first driven plate 121 of the first connecting rod mechanism 12 and the second driven plate 221 of the second connecting rod mechanism 22 are installed on the main shaft 6, and the flip member 3 is located between the first driven plate 121 and the second driven plate 221; the toggle member 4 is rotatably arranged above the flip member 3 and is also located between the first side plate 103 and the second side plate 104, and the first electromagnetic mechanism 7 and the second electromagnetic mechanism 8 are symmetrically arranged on both sides below the flip member 3.

[0093] like Figure 9 The figure shows an embodiment of the flip member 3 described in the present application. A circular hole is provided in the middle region of the flip member 3, serving as a flip member mounting hole 33, which can be rotatably mounted on the main shaft 6. Two hollow arc-shaped slots are provided on both sides of the lower portion of the flip member 3, serving as a first arc slot 31 and a second arc slot 32, respectively. A plurality of gear teeth are provided on the upper portion of the flip member 3, forming a first linkage portion 34 of a gear structure for linkage connection with the toggle member 4. Preferably, the flip member 3 of this embodiment includes two identical flip plates 30, each of which is provided with a flip member mounting hole 33, a first arc slot 31, a second arc slot 32, and a first linkage portion 34. The two flip plates 30 are spaced apart and arranged opposite to each other and connected by a plurality of fixed shafts.
