Description

Technical Field

[0001] This utility model relates to the field of low-voltage electrical appliances, specifically to a dual power switch and operating mechanism. Background Technology

[0002] A dual-power switch is a commonly used low-voltage electrical distribution device used to switch between a primary power supply and a backup power supply. This ensures that if one power supply fails or stops supplying power, the other power supply can be quickly switched to guarantee normal power supply to the load circuit. Existing dual-power switches use an operating mechanism to drive two sets of contact mechanisms within the switch to control the primary and backup power supplies. Since the two sets of contact mechanisms cannot close simultaneously, the operating mechanism typically uses one or two locking devices to lock it when the contacts need to open. These locking devices usually include complex linkage assemblies, making them complex, inconvenient to operate, and costly. Summary of the Invention

[0003] The purpose of this utility model is to overcome at least one defect of the prior art and provide a dual power switch and operating mechanism.

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

The rocker arm is rotatably mounted between the two electromagnetic drive mechanisms. Each electromagnetic drive mechanism switches between a first position and a second position. It also includes an interlocking mechanism, which includes an interlocking element. The interlocking element is rotatably mounted between the rocker arm and an electromagnetic locking device. Each electromagnetic drive mechanism is linked to the interlocking element, so that the two electromagnetic drive mechanisms cooperate to drive the interlocking element to swing between two closed positions and one open position.

[0006] The interlocking component abuts against the electromagnetic locking device. The electromagnetic locking device switches between a first locking position and a second locking position. Before the interlocking component switches from the closed position to the double open position, the switching position of the electromagnetic locking device is used to change the abutment position between the interlocking component and the electromagnetic locking device.

[0007] Preferably, when the interlocking component swings to a closed position, one of the electromagnetic drive mechanisms is in a first position, the other electromagnetic drive mechanism is in a second position, and the electromagnetic locking device is in the first locked position.

[0008] When the interlocking component swings to the double-split position, and the two electromagnetic drive mechanisms are in the second position, the electromagnetic locking device is in the second locked position.

[0009] Preferably, the interlocking component has two closing abutment parts and one opening abutment part, and the two closing abutment parts and the one opening abutment part are three independent grooves. The electromagnetic locking device includes an opening moving iron core, and a limiting shaft is provided at one end of the opening moving iron core. When the opening moving iron core is in the first locked position, the limiting shaft abuts against the opening abutment part and limits its movement. When the opening moving iron core is in the second locked position, the limiting shaft abuts against the closing abutment part and limits its movement.

[0010] Preferably, each electromagnetic drive mechanism is connected to an interlocking component by a drive link, the interlocking component slides and rotates relative to the rocker arm, the edge of the interlocking component is limited and abuts against the electromagnetic locking device, and the two drive links are respectively hinged to the middle of the interlocking component.

[0011] Preferably, one end of the interlocking member is provided with a sliding shaft, one end of the rocker arm is rotatably assembled, a sliding groove is provided between the middle of the rocker arm and the other end of the rocker arm, and the sliding shaft slides linearly along the sliding groove;

[0012] The interlocking component has a hinge shaft in the middle, and one end of each of the two drive linkages is hinged to the hinge shaft.

[0013] The other end of the interlocking component is provided with an assembly shaft for rotational assembly, and the edge of the other end of the interlocking component abuts and limits the movement with the electromagnetic locking device.

[0014] Preferably, the other end of the interlocking member is provided with two closing bosses and one opening boss, and the opening boss is located between the two closing bosses. The edge of the interlocking member connected between the closing boss and the opening boss forms a closing abutment part, and the edge of the opening boss is recessed to form an opening abutment part. The closing abutment part and the opening abutment part respectively abut against the electromagnetic locking device.

[0015] Preferably, at least one micro switch is provided, which is triggered by the hinge axis.

[0016] Preferably, the interlocking mechanism further includes at least one support plate, the interlocking component is rotatably mounted on the support plate, the support plate has a track groove, and the hinge shaft slides along the track groove.

[0017] Preferably, the interlocking mechanism includes two spaced-apart support plates, the interlocking element and the electromagnetic locking device are located between the pair of support plates, and at least one support plate is provided with a guide groove, which restricts the movement of the electromagnetic locking device between a first locking position and a second locking position.

[0018] Preferably, a micro switch triggered by a hinge shaft is configured at each end of the track groove.

[0019] Preferably, the interlocking mechanism further includes at least one pair of elastic elements, with at least one elastic element connected between each electromagnetic drive mechanism and the sliding shaft, and the elastic element providing the swinging reset force.

[0020] Preferably, it further includes a pair of side plates disposed on the mounting plate, forming an assembly cavity between the side plates and the mounting plate. The rocker arm is rotatably disposed in the middle of the assembly cavity. Two electromagnetic drive mechanisms are disposed in the assembly cavities on opposite sides of the rocker arm. The interlocking mechanism is disposed between the two electromagnetic drive mechanisms and the interlocking component.

[0021] This utility model also provides a dual power switch, including a switching mechanism, the switching mechanism including at least one moving contact and at least one pair of stationary contacts, each pair of stationary contacts being connected to the main power supply and the backup power supply respectively, and also including the operating mechanism as described above, the moving contact being connected to the output shaft of the rocker arm.

[0022] The dual power switch and operating mechanism of this utility model have an interlocking component in the interlocking mechanism that can link the electromagnetic drive mechanism and the rocker arm together, and achieve position locking by limiting and abutting the interlocking component through an electromagnetic locking device. This simplifies the existing linkage assembly and locking device and has the advantages of simple structure, convenient operation and low cost.

[0023] In addition, the interlocking component and the limiting shaft of the moving iron core in the electromagnetic locking device are in a limiting contact. In particular, the closing contact part and the opening contact part are both groove structures, which further simplifies the structure, reduces the volume and improves the stability of the fit.

[0024] In addition, by setting a micro switch, it is beneficial to provide feedback on the position status of the interlocking components.

[0025] In addition, by setting a support plate, the support plate provides an assembly position for the interlocking components. In particular, the support plate can also limit the movement trajectory of the electromagnetic locking device, ensuring the coordination stability of the interlocking mechanism.

[0026] In addition, by setting up an elastic element, which provides a restoring force to the rocker arm, the stability of the overall mechanism is ensured. Attached Figure Description

Detailed Implementation

[0045] The specific embodiments of the dual power switch and operating mechanism of this utility model are further described below with reference to the accompanying drawings. The dual power switch and operating mechanism of this utility model are not limited to the descriptions in the following embodiments.

[0046] like Figure 1-3 As shown, the operating mechanism of the dual-power switch includes a rocker arm 2 and two electromagnetic drive mechanisms 3. The rocker arm 2 is rotatably mounted between the two electromagnetic drive mechanisms 3. The rocker arm 2 swings between two closed positions and a double-open position, with the double-open position located between the two closed positions. The rocker arm 2 is connected to an output shaft 20 for driving two sets of contact mechanisms in the switch mechanism. One set of contact mechanisms controls the connection and disconnection of the main power supply, and the other set of contact mechanisms controls the connection and disconnection of the backup power supply. When the rocker arm 2 swings to a closed position, one set of contact mechanisms in the switch mechanism closes, and the other set of contact mechanisms... The head mechanism is disconnected, meaning that the normal power supply or the backup power supply is connected. When the rocker arm 2 swings to the double-open position, both sets of contact mechanisms are disconnected, meaning that both the normal power supply and the backup power supply are disconnected. Each electromagnetic drive mechanism 3 is used to drive the rocker arm 2 to swing between the closed position and the double-open position. The electromagnetic drive mechanism 3 switches between the first position and the second position. Typically, when the rocker arm 2 swings to a closed position, one electromagnetic drive mechanism 3 is in the first position and the other electromagnetic drive mechanism 3 is in the second position. When the rocker arm 2 swings to the double-open position, both electromagnetic drive mechanisms 3 are in the second position.

[0047] Typically, each electromagnetic drive mechanism 3 is provided with a linkage assembly and a locking device between it and the rocker arm 2. The linkage assembly is connected between each electromagnetic drive mechanism 3 and the rocker arm 2 to drive the rocker arm 2 to switch positions. The locking device is used to lock the linkage assembly and / or the rocker arm 2, so that the rocker arm 2 is held in the engaged position or the split position. The locking device needs to be unlocked before the rocker arm 2 switches positions.

[0048] The improvement of this application lies in the fact that the linkage assembly and locking device are no longer provided in the dual power switch operating mechanism, such as... Figure 1-3 As shown, the dual power switch operating mechanism also includes an interlocking mechanism, which includes an interlocking component 6. The interlocking component 6 is rotatably mounted between the rocker arm 2 and the electromagnetic locking device 4. Each electromagnetic drive mechanism 3 is linked to the interlocking component 6, so that the two electromagnetic drive mechanisms 3 cooperate to drive the interlocking component 6 to swing between two closed positions and one double-open position. The interlocking component 6 abuts against the electromagnetic locking device 4. The electromagnetic locking device 4 switches between a first locking position and a second locking position. Before the interlocking component 6 switches from the closed position to the double-open position, the switching position of the electromagnetic locking device 4 is used to change the abutment position between the interlocking component 6 and the electromagnetic locking device 4.

[0049] Thus, the interlocking component 6 in its interlocking mechanism can link the electromagnetic drive mechanism 3 and the rocker arm 2 together, and the electromagnetic locking device 4 can limit and abut against the interlocking component 6 to achieve position locking, which simplifies the existing linkage assembly and locking device, and has the advantages of simple structure, convenient operation and low cost.

[0050] Specifically, such as Figure 2 , 3 As shown, when the interlocking member 6 swings to a closed position, one of the electromagnetic drive mechanisms 3 is in the first position, the other electromagnetic drive mechanism 3 is in the second position, and the electromagnetic locking device 4 is in the second locking position. When the interlocking member 6 swings to the double open position, when both electromagnetic drive mechanisms 3 are in the second position, the electromagnetic locking device 4 is in the first locking position. That is, when the main power supply or the backup power supply is turned on, the electromagnetic locking device 4 is in the first locking position, and when both the main power supply and the backup power supply are in the off state, the electromagnetic locking device 4 is in the second locking position.

[0051] In this configuration, the interlocking component 6 slides and rotates relative to the rocker arm 2, and the edge of the interlocking component 6 abuts against the electromagnetic locking device 4. Preferably, each electromagnetic drive mechanism is linked to the interlocking component 6 via a drive link 5, and the two drive links 5 are respectively hinged to the middle of the interlocking component 6. Further, one end of the interlocking component 6 slides and rotates with the rocker arm 2, and the other end of the interlocking component 6 abuts against the electromagnetic locking device 4. Specifically, as shown... Figure 2 , 3As shown in Figure 15, the interlocking component 6 is provided with two closing abutment parts 631 and one opening abutment part 641, and the two closing abutment parts 631 and the one opening abutment part 641 are three independent grooves. The electromagnetic locking device 4 includes an opening moving iron core 41, and one end of the opening moving iron core 41 is provided with a limiting shaft 45. When the interlocking component 6 and the electromagnetic locking device 4 are in the switching state, the limiting shaft 45 switches between the opening abutment part 641 and an adjacent closing abutment part 631. That is, when the opening moving iron core 41 is in the first position, the limiting shaft 45 abuts against a closing abutment part 631 and locks the rocker arm 2 in a closing position. At this time, the normal power supply or the backup power supply is turned on. When the opening moving iron core 41 is in the second position, the limiting shaft 45 abuts against the opening abutment part 641 and locks the rocker arm 2 in a double opening position. At this time, both the normal power supply and the backup power supply are turned off. In addition, the active iron core 31 in each electromagnetic drive mechanism can also be directly linked with the interlocking component 6, which can eliminate the drive linkage 5. However, the size of the active iron core 31 may be large, and the required electromagnetic force is also large, which is not conducive to reducing volume, saving space and reducing cost.

[0052] Preferably, the interlocking member 6 is provided with at least three spaced shafts. One shaft is provided as a sliding shaft 61 at one end of the interlocking member 6. The rocker arm 2 is provided with a slide groove 21 for sliding assembly of the sliding shaft 61. The sliding shaft 61 moves linearly along the slide groove 21, and the interlocking member 6 and the rocker arm 2 are rotatably connected through the sliding shaft 61. Another shaft is provided as a hinge shaft 62 in the middle of the interlocking member 6 for hinge connection with two drive linkages 5. A third shaft is provided as an assembly shaft 65 at the other end of the interlocking member 6 for rotatably assembling the interlocking member 6.

[0053] Preferably, the interlocking member 6 is provided with two closing bosses 63 and one opening boss 64. The opening boss 64 and an adjacent closing boss 63 form a closing abutment part 631. The opening boss 64 is provided with an opening abutment part 641. The limiting shaft 45 is respectively limited and abutted with the closing abutment part 631 or the opening abutment part 641. That is, when the normal power supply or the backup power supply is turned on, the limiting shaft 45 abuts and limits the closing abutment part 631, so that the interlocking member 6 is kept in a closing position. At this time, the electromagnetic locking device 4 is in the first locking position. When both the normal power supply and the backup power supply are turned off, the limiting shaft 45 abuts and limits the opening abutment part 641. At this time, the electromagnetic locking device 4 is in the second locking position. The closing abutment part 631 and the opening abutment part 641 are preferably groove structures, which helps to ensure the stability of the abutment.

[0054] Furthermore, such as Figure 2As shown, the interlocking mechanism can also be equipped with a micro switch 9, which provides feedback on the position status of the interlocking element 6; the interlocking mechanism can also be equipped with an elastic element 7, which is connected to the interlocking element 6 to provide a reset force. The elastic element 7 can be used to reset the rocker arm 2, the interlocking element 6, and the active iron core 31 in the electromagnetic drive mechanism 3.

[0055] Combination Figure 1-16 A specific embodiment of the operating mechanism of a dual power switch is provided.

[0056] like Figure 1-10 As shown, the dual-power switch operating mechanism includes a mounting plate 12, on which a pair of side plates 11 are provided. An assembly cavity 10 is formed between the side plates 11 and the mounting plate 12. A rocker arm 2 is rotatably mounted in the middle of the assembly cavity 10. The rocker arm 2 switches between two closed positions and one double-open position, with the double-open position located between the two closed positions. One of the side plates 11 has a linkage hole 13. An output shaft 20 connected to the rocker arm 2 passes through the linkage hole 13 and exits the assembly cavity 10 to drive the two sets of contact mechanisms of the switch. Within the assembly cavities 10 on opposite sides of the rocker arm 2, there are... Two electromagnetic drive mechanisms 3 are provided, and the two electromagnetic drive mechanisms 3 form a symmetrical structure about the rocker arm 2. Each electromagnetic drive mechanism 3 switches between a first position and a second position. In this embodiment, the electromagnetic drive mechanism 3 adopts an existing structure. Each electromagnetic drive mechanism 3 is arranged along the horizontal direction in the figure. The active iron core 31 of each electromagnetic drive mechanism 3 faces the rotation center of the rocker arm 2. When the electromagnetic drive mechanism 3 is in the first position, the active iron core 31 is close to the rotation center of the rocker arm 2. When the electromagnetic drive mechanism 3 is in the second position, the active iron core 31 is away from the rotation center of the rocker arm 2.

[0057] An interlocking mechanism is provided in the assembly cavity 10 between the two electromagnetic drive mechanisms 3 and the rocker arm 2. The interlocking mechanism includes an interlocking component 6 and an electromagnetic locking device 4. The interlocking component 6 is rotatably assembled between the rocker arm 2 and the electromagnetic locking device 4. A drive link 5 is connected between each electromagnetic drive mechanism 3 and the interlocking component 6. When the electromagnetic drive mechanism 3 is switching positions, the drive link 5 can drive the rocker arm 2 to swing between two closed positions and one double open position, and the double open position is located between the two closed positions.

[0058] The interlocking component 6 and the electromagnetic locking device 4 abut against each other to lock the position of the interlocking component 6. The electromagnetic locking device 4 switches between the first locking position and the second locking position. In this embodiment, the electromagnetic locking device 4 can also adopt an existing structure. The electromagnetic locking device 4 is arranged in the vertical direction shown in the figure. The opening moving iron core 41 of the electromagnetic locking device 4 faces the rotation center of the rocker arm 2. When the electromagnetic locking device 4 is in the first locking position, the opening moving iron core 41 is closer to the rotation center of the rocker arm 2. When the electromagnetic locking device 4 is in the second locking position, the opening moving iron core 41 is away from the rotation center of the rocker arm 2. Before the interlocking component 6 switches from the closed position to the double open position, the electromagnetic locking device 4 switches positions to change the abutment position between the interlocking component 6 and the electromagnetic locking device 4.

[0059] like Figure 3 , 5 As shown in Figures 7 and 9, the interlocking member 6 slides and rotates relative to the rocker arm 2. The edge of the interlocking member 6 abuts against the electromagnetic locking device 4. The two drive linkages 5 are respectively hinged to the middle of the interlocking member 6. Specifically, one end of the interlocking member 6 slides and rotates with the rocker arm 2. Typically, a sliding shaft 61 and a sliding groove 21 are provided between the interlocking member 6 and the rocker arm 2. A hinge shaft 62 is arranged in the middle of the interlocking member 6, which is used to hinge with the two drive linkages 5. The other end of the interlocking member 6 is rotatably assembled in the assembly cavity 10. The other edge of the interlocking member 6 is in contact with the electromagnetic locking device 4. Specifically, the edge of the interlocking member 6 can be provided with two closing contact parts 631 and one opening contact part 641, wherein the opening contact part 641 is located between the two closing contact parts 631. The opening moving iron core 41 of the electromagnetic locking device 4 is provided with a limiting shaft 45. Before the interlocking member 6 is switched from the closing position to the double opening position, the electromagnetic locking device 4 is switched from the first locking position to the second locking position, thereby causing the limiting shaft 45 to switch from the closing contact part 631 to the opening contact part 641.

[0060] Combination Figure 11 A rocker arm 2 structure is provided for use in this embodiment, such as Figure 11 As shown, the rocker arm 2 includes a strip plate body. One end of the strip plate body is provided with a square shaft hole 22. The shaft hole 22 is used to connect with the output shaft 20. The output shaft 20 passes through the side plate 11 to drive the two sets of contact mechanisms of the switch to perform opening and closing actions. The middle part of the rocker arm 2 is provided with a sliding groove 21. The sliding groove 21 extends along the axial direction of the strip plate body in a direction away from the shaft hole 22.

[0061] Combination Figure 15 A structure for the interlocking component 6 applied in this embodiment is provided, such as... Figure 15As shown, the interlocking component 6 includes a strip-shaped interlocking body. The interlocking body has three through holes spaced apart along the axial direction of the interlocking body. The three through holes are, in sequence, a first through hole 601, a second through hole 602, and a third through hole 603. Each through hole contains a shaft. One of the shafts serves as a sliding shaft 61 and is located at one end of the interlocking body. That is, a sliding shaft 61 is located in the first through hole 601. The sliding shaft 61 is slidably engaged with the sliding groove 21 of the rocker arm 2, and the interlocking component 6 and the rocker arm 2 can also be rotatably connected through the sliding shaft 61. A shaft located in the middle of the interlocking body serves as a hinge shaft 62. That is, a hinge shaft 62 is located in the second through hole 602. One end of each of the two drive linkages 5 is hinged to the hinge shaft 62, allowing the electromagnetic drive mechanism 3 to drive the interlocking component 6 to rotate. The other shaft serves as an assembly shaft 65 located at the other end of the interlocking body. The linkage can rotatably assemble the interlocking component 6 into the assembly cavity 10 through the assembly shaft 65. Figure 15 In the middle, the third through hole 603 is used to set the assembly shaft 65.

[0062] The interlocking body has two closing bosses 63 and one opening boss 64 at the end away from the sliding shaft 61. In the figure, the two closing bosses 63 are respectively located on opposite sides of the interlocking body. The end of the interlocking body away from the sliding shaft 61 extends outward to form the opening boss 64, that is, the opening boss 64 is located between the two closing bosses 63. An L-shaped groove, serving as a closing abutment 631, is formed between the opening boss 64 and an adjacent closing boss 63. This groove connects to the closing boss 63. The edge of the interlocking member 6 between the 3 and the tripping boss 64 forms a closing abutment part 631, and a groove is formed at the edge of the tripping boss 64 as a tripping abutment part 641. The limiting shaft 45 of the electromagnetic locking device 4 can abut and limit the closing abutment part 631 or the tripping abutment part 641 respectively, thereby locking the interlocking member 6 in the closing position or the double-opening position. The specific shapes of the closing boss 63 and the tripping boss 64, as well as the closing abutment part 631 and the tripping abutment part 641, are not limited.

[0063] In addition, in this embodiment, the interlocking component 6 is formed by two interlocking bodies spaced apart. The sliding shaft 61, the hinge shaft 62 and the assembly shaft 65 are respectively connected between the two interlocking bodies. At this time, the rocker arm 2 and the drive linkage 5 are both located between the two interlocking bodies.

[0064] In this embodiment, the electromagnetic locking device 4 adopts an existing structure, such as... Figure 14As shown, the electromagnetic locking device 4 includes a tripping coil assembly 44 and a tripping moving iron core 41. A tripping magnetic yoke 43 surrounds the outside of the tripping coil assembly 44. One end of the tripping moving iron core 41 is slidably mounted in the middle of the tripping coil assembly 44. One end of the tripping moving iron core 41 located in the middle of the tripping coil assembly 44 is spaced apart from the tripping magnetic yoke 43. A locking platform is located in the middle of the tripping moving iron core 41, outside the tripping coil and passing through the tripping magnetic yoke 43. A locking platform is located in the middle of the tripping moving iron core 41. A tripping mechanism is sleeved on one end of the tripping moving iron core 41 located inside the tripping coil assembly 44. The two ends of the brake spring and the opening spring abut against the magnetic yoke and the locking platform, respectively. The other end of the opening moving iron core 41 is provided with a limiting shaft 45. When the electromagnetic locking device 4 is in the first locking position, the opening moving iron core 41 and the opening magnetic yoke 43 are spaced apart and opposite each other. When the electromagnetic locking device 4 is in the second locking position, the opening moving iron core 41 and the opening magnetic yoke 43 are attracted together, and the opening reset spring 42 is compressed. When the opening reset spring 42 releases its elastic force, it can drive the opening moving iron core 41 and the opening magnetic yoke 43 to be spaced apart and opposite each other again, that is, to make the electromagnetic locking device 4 switch back to the first locking position.

[0065] In this embodiment, as Figure 2-9 As shown, the interlocking mechanism also includes at least one support plate 8. The interlocking member 6 is rotatably mounted on the support plate 8. A track groove 81 can be provided on the support plate 8 to restrict the movement trajectory of the hinge shaft 62. Alternatively, a guide groove 82 can be provided on the support plate 8 to restrict the movement trajectory of the limiting shaft 45 of the electromagnetic locking device 4. Preferably, there are two support plates 8, spaced apart. The interlocking member 6 and the electromagnetic locking device 4 are both located between the pair of support plates 8. At least one of the support plates 8 has a track groove 81 and a guide groove 82. At least one end of the hinge shaft 62 slides along the track groove 81, and the guide groove 82 restricts the movement of the limiting shaft 45 of the electromagnetic locking device 4 between the first locking position and the second locking position. Of course, the interlocking mechanism can also omit the support plate 8, in which case the track groove 81 and the guide groove 82 can be provided on the side plate 11.

[0066] like Figure 16As shown, the support plate 8 includes a plate body with a convex edge formed by bending one end of the plate body. The support plate 8 can be fixed to the mounting plate 12 by setting a fixing member on the convex edge. A connecting hole is provided in the middle of the plate body. The assembly shaft 65 on the interlocking member 6 cooperates with the connecting hole to rotate the interlocking member 6 onto the support plate 8. A strip-shaped guide groove 82 is opened on the plate body between the connecting hole and the convex edge. The limiting shaft 45 of the electromagnetic locking device 4 slides along the guide groove 82. An arc-shaped groove is provided at one end of the plate body away from the convex edge, which serves as a track groove 81. The center of the arc-shaped groove is the axis of the connecting hole. The hinge shaft 62 of the interlocking member 6 slides along the track groove 81. When the hinge shaft 62 rotates to one end of the track groove 81, the rocker arm 2 and the interlocking member 6 swing to a closed position. When the hinge shaft 62 rotates to the middle of the track groove 81, the rocker arm 2 and the interlocking member 6 swing to a double open position.

[0067] Preferably, at least one micro switch 9 is also provided in the assembly cavity 10. The micro switch 9 is triggered by the hinge shaft 62, thereby enabling the micro switch 9 to provide feedback on the position of the rocker arm 2. In this embodiment, two micro switches 9 are provided on the support plate 8, each micro switch 9 corresponding to one end of the track groove 81. The button of the micro switch 9 is located on the movement track of the hinge shaft 62.

[0068] Furthermore, the interlocking mechanism is also equipped with at least one pair of elastic elements 7. Each electromagnetic drive mechanism 3 is connected to the sliding shaft 61 with at least one elastic element 7. The elastic element 7 provides the swinging reset force for the rocker arm 2, the interlocking element 6 and the active iron core 31 in the electromagnetic drive mechanism 3. The elastic element 7 is preferably a spring. One end of the elastic element 7 is connected to the sliding shaft 61. In the figure, one end of the elastic element 7 is located between the two interlocking bodies, and the other end of the elastic element 7 is connected to an electromagnetic drive mechanism 3.

[0069] In this embodiment, the electromagnetic drive mechanism 3 adopts existing technology, such as... Figure 12 , 13As shown, the electromagnetic drive mechanism 3 includes a main coil assembly 34, an active iron core 31, and a main stationary iron core 32. A main magnetic yoke 35 is arranged around the outside of the main coil assembly 34. The main stationary iron core 32 is located at one end inside the main coil assembly 34. One end of the active iron core 31 is slidably mounted inside the main coil assembly 34 and is spaced apart from the main stationary iron core 32. A main return spring 33 is arranged between the active iron core 31 and the main stationary iron core 32. The other end of the active iron core 31 extends out of the main coil assembly 34 and is connected to a drive linkage 5. When the electromagnetic drive mechanism 3 is in the first position, the active iron core 31 and the main stationary iron core 32 are spaced apart from each other. When the electromagnetic drive mechanism 3 is in the second position, the active iron core 31 and the main stationary iron core 32 are attracted together, and the main return spring 33 is compressed. In this embodiment, a spring connection part 351 is provided on the main magnetic yoke 35. One end of the elastic member 7 can be connected to the spring connection part 351. Of course, the spring connection part 351 can also be provided at other fixed positions of the electromagnetic drive mechanism 3, such as on the coil skeleton in the main coil assembly 34.

[0070] Combination Figure 1-9 Briefly describe the working principle of this embodiment. Figure 2-9 The left side is the standby side, and the right side is the normal side. The electromagnetic drive mechanism 3, drive link 5, and elastic element 7 corresponding to the standby side are the standby electromagnetic drive mechanism, standby drive link, and standby elastic element, respectively. The electromagnetic drive mechanism 3, drive link 5, and elastic element 7 corresponding to the normal side are the normal electromagnetic drive mechanism, normal drive link, and normal elastic element, respectively. The two closing bosses 63 on the interlocking part 6 are also divided into normal closing bosses and standby closing bosses according to their correspondence with the normal side and standby side. The groove between the normal closing boss and the opening boss 64 is the normal closing abutment part, and the groove between the standby closing boss and the opening boss is the standby closing abutment part.

[0071] like Figure 4 , 5 As shown, when the normal power supply needs to be turned on, the active iron core 31 in the normal electromagnetic drive mechanism is attracted to the main stationary iron core 32. The active iron core 31 of the normal electromagnetic drive mechanism drives the rocker arm 2 and the interlocking member 6 to swing to the closed position on the normal side through the connected drive linkage 5. That is, the rocker arm 2 and the interlocking member 6 swing to the right and drive the output shaft 20 to control the normal power supply to be turned on. The sliding shaft 61 slides to the end of the slide groove 21 away from the shaft hole 22. At the same time, the two elastic members 7 connected to the sliding shaft 61 also deform accordingly. The normal elastic member is compressed and the spare elastic member is stretched. The hinge shaft 62 is located at the end of the track groove 81 near the normal electromagnetic drive mechanism and triggers a micro switch 9 accordingly. The electromagnetic locking device 4 is in the first locking position. The limiting shaft 45 is located at the end of the guide groove 82 near the connecting hole and abuts against the normal closing contact part 631 to limit the movement, locking the interlocking member 6 and the rocker arm 2 in the closed position.

[0072] like Figure 6 , 7 As shown, when the main power supply needs to be disconnected, the electromagnetic locking device 4 switches from the first locking position to the second locking position. That is, the tripping moving iron core 41 and the tripping magnetic yoke 43 attract each other, the limit shaft 45 moves away from the connection hole, and the tripping reset spring 42 is compressed. Subsequently, the active iron core 31 of the main electromagnetic drive mechanism separates from the main stationary iron core 32 under the joint drive of the main reset spring 33 and the spare elastic element. The active iron core 31 of the main electromagnetic drive mechanism 3 is driven to rock through the connected drive linkage 5. Arm 2 and interlocking member 6 swing together to the double-open position, that is, rocker arm 2 and interlocking member 6 swing to the left. Sliding shaft 61 slides to one end of the slide groove 21 near shaft hole 22. The normal elastic element returns to its original state. Hinged shaft 62 slides to the middle of track groove 81. The limiting shaft 45, which is switched to the second position, switches to the abutment position with interlocking member 6, which is switched to the double-open position. That is, the limiting shaft 45 switches from the normal closing abutment part to the double opening abutment part. When rocker arm 2 rotates to the double-open position, the drive output shaft 20 controls the normal power supply to be disconnected.

[0073] like Figure 8 , 9 As shown, when the backup power needs to be turned on, the active iron core 31 in the backup electromagnetic drive mechanism 3 attracts the main stationary iron core 32. The active iron core 31 of the backup electromagnetic drive mechanism 3 drives the rocker arm 2 and the interlocking member 6 to swing to the closing position on the backup side through the connected drive linkage 5. That is, the rocker arm 2 and the interlocking member 6 swing to the left and drive the output shaft 20 to control the backup power to be turned on. The sliding shaft 61 slides to the end of the slide groove 21 away from the shaft hole 22. At the same time, the two elastic members 7 connected to the sliding shaft 61 also deform accordingly. The backup elastic member is compressed and the regular elastic member is stretched. The hinge shaft 62 is located at the end of the track groove 81 near the backup electromagnetic drive mechanism and triggers a micro switch 9 accordingly. The electromagnetic locking device 4 is in the first locking position. The limiting shaft 45 is located at the end of the guide groove 82 near the connecting hole and abuts against the backup closing abutment part to limit the movement, locking the interlocking member 6 and the rocker arm 2 in the closing position.

[0074] like Figure 6 , 7As shown, when the backup power supply needs to be disconnected, the electromagnetic locking device 4 switches from the first locking position to the second locking position. That is, the tripping moving iron core 41 and the tripping magnetic yoke 43 attract each other, the limit shaft 45 moves away from the connection hole, the tripping reset spring 42 is compressed, and then the active iron core 31 of the backup electromagnetic drive mechanism separates from the main stationary iron core 32 under the joint drive of the main reset spring 33 and the backup elastic element. The active iron core 31 of the backup electromagnetic drive mechanism drives the rocker arm through the connected drive linkage 5. 2 and interlocking member 6 swing together to the double-open position, that is, rocker arm 2 and interlocking member 6 swing to the right, sliding shaft 61 slides to one end of the slide groove 21 near shaft hole 22, the spare elastic member returns to its original state, hinge shaft 62 slides to the middle of track groove 81, the limit shaft 45 switched to the second position and the interlocking member 6 switched to the double-open position switch the contact position, that is, the limit shaft 45 switches from the spare closing contact part to the double-open contact part, when rocker arm 2 rotates to the double-open position, drive output shaft 20 controls the backup power supply to be disconnected.

[0075] A dual power switch (not shown) includes a switching mechanism comprising multiple phase pole units. Each phase pole unit includes a moving contact and a pair of stationary contacts. Each pair of stationary contacts cooperates with the moving contact to form two sets of contact mechanisms. One set of contact mechanisms is used to control the connection and disconnection of the main power supply, and the other set of contact mechanisms is used to control the connection and disconnection of the backup power supply. That is, one stationary contact in each pair of stationary contacts is used to connect to the main power supply, and the other stationary contact is used to connect to the backup power supply. The moving contact is connected to the output shaft 20 of the operating mechanism, so that the output shaft 20 can drive the moving contacts of the multiple phase pole units to cooperate with their respective stationary contacts.
