[0049] As described above, in some conventional dual power transfer switches, due to the lack of intelligent control mechanism, it is difficult to accurately manage the action of the energy storage structure, which not only affects the transfer rate, but also reduces the safety and reliability of the transfer process to some extent.

[0050] Embodiments of the present disclosure provide a bidirectional energy storage device and a dual power transfer switch. The bidirectional energy storage device includes a first energy storage assembly, a second energy storage assembly, a first drive assembly, a second drive assembly, a first position detection unit, a second position detection unit, a third position detection unit, and a fourth position detection unit. The first energy storage assembly and the second energy storage assembly are adjacently arranged, and each of the energy storage assemblies is adapted to switch between a first gate position preparation position, a first gate position, a second gate position preparation position, and a second gate position. The first drive assembly is coupled to the first energy storage assembly and is adapted to drive a movable contact of a first power source under the drive of the first energy storage assembly. The second drive assembly is coupled to the second energy storage assembly and is adapted to drive a movable contact of a second power source under the drive of the second energy storage assembly. The second drive assembly is coupled to the first drive assembly. The first position detection unit is arranged adjacent to the first energy storage assembly and can detect whether the first energy storage assembly is in the first gate position. The second position detection unit is arranged adjacent to the second energy storage assembly and can detect whether the second energy storage assembly is in the second gate position. The third position detection unit is arranged adjacent to the second drive assembly and can detect whether the second energy storage assembly is in the first gate position preparation position. The fourth position detection unit is arranged adjacent to the first drive assembly and can detect whether the first energy storage assembly is in the second gate position preparation position. With this arrangement, during the operation of the bidirectional energy storage assembly, the position state of the energy storage assembly is accurately monitored by the first position detection unit, the second position detection unit, the third position detection unit, and the fourth position detection unit, and the action of the bidirectional energy storage device can be intelligently managed, thereby improving the switching efficiency and reliability of the bidirectional energy storage device. The principles of the present disclosure will be described in detail below with reference to the accompanying drawings. Figures 1 to 19

[0051] As shown in Figure 1 , the bidirectional energy storage device includes a first energy storage assembly 10, a second energy storage assembly 20, a first drive assembly 30, a second drive assembly 40, a first position detection unit 51, a second position detection unit 52, a third position detection unit 53, and a fourth position detection unit 54.

[0052] The first energy storage assembly 10 and the second energy storage assembly 20 are adjacently arranged, and each of the energy storage assemblies can switch between a first gate position preparation position, a first gate position, a second gate position preparation position, and a second gate position. With this arrangement, through switching between the four positions, the energy storage assembly can realize energy storage and release, and the transition of the corresponding operation mode.

[0053] It should be understood that the bidirectional energy storage device can be connected with a main power source and a backup power source, and the main power source and the backup power source can be switched between a closed position and an open position. In order to ensure the continuity and safety of power supply, the gate positions of the main power source and the backup power source are opposite.

[0054] ​With the first energy storage component 10 and the second energy storage component 20 in the first switch-ready position, the main power supply is in the open position and the backup power supply is in the closed position. At this time, the energy storage components perform energy storage operations, preparing to switch the main power supply from the open position to the closed position and the backup power supply from the closed position to the open position.

[0055] When the first energy storage component 10 and the second energy storage component 20 are in the first closed position, the main power supply is in the closed position and the backup power supply is in the open position.

[0056] With the first energy storage component 10 and the second energy storage component 20 in the second switch-ready position, the main power supply is in the closed position and the backup power supply is in the open position. At this time, the energy storage components perform energy storage operations, preparing to switch the main power supply from the closed position to the open position and the backup power supply from the open position to the closed position.

[0057] When the first energy storage component 10 and the second energy storage component 20 are in the second switch position, the main power supply is in the open position and the backup power supply is in the closed position.

[0058] In this way, the first energy storage component 10 and the second energy storage component 20 can be cyclically switched between the first gate position preparation position, the first gate position, the second gate position preparation position, and the second gate position, thereby ensuring the continuity of the bidirectional energy storage device's operation.

[0059] In some embodiments, the first energy storage component 10 and the second energy storage component 20 may include an elastic element that can store mechanical energy and release it when needed. When a force is applied to the elastic element to deform it (such as compressing or stretching), the work done by the force is stored within the elastic element. When the force is released or its direction changes, the elastic element will return to its original shape, thereby releasing the stored energy in the form of mechanical motion.

[0060] In other embodiments, the energy storage component may also include a capacitor that can be rapidly charged and discharged and has a long cycle life. The capacitor can store charge to drive the switching between the main power supply and the backup power supply in the closed and open positions.

[0061] It should be understood that energy storage components may also employ other energy storage elements besides elastic elements and capacitors, and this disclosure is not intended to limit them.

[0062] like Figure 1 As shown, the first drive component 30 is coupled to the first energy storage component 10. When the first energy storage component 10 is ready to store energy, it can drive the first drive component 30, thereby causing the first drive component 30 to drive the moving contact of the main power supply. In addition, the first drive component 30 can also drive the first energy storage component 10 to store energy.

[0063] The second drive component 40 is coupled to the second energy storage component 20. When the second energy storage component 20 is ready to store energy, it can drive the second drive component 40, which in turn drives the moving contact of the backup power supply. Furthermore, the second drive component 40 can also drive the second energy storage component 20 to store energy. The second drive component 40 is coupled to the first drive component 30, allowing the operation of the first energy storage component 10 and the second energy storage component 20 to be synchronized.

[0064] like Figure 1 As shown, in the bidirectional energy storage device, a first position detection unit 51 is disposed adjacent to the first energy storage component 10. The first position detection unit 51 can monitor and confirm whether the first energy storage component 10 has reached the first gate position. A second position detection unit 52 is disposed adjacent to the second energy storage component 20 and can be used to determine whether the second energy storage component 20 is in the second gate position. In this way, the first position detection unit 51 and the second position detection unit 52 can provide real-time feedback, thereby enabling the control system to understand the current position status of the energy storage component and make corresponding adjustments or commands.

[0065] The third position detection unit 53 is located adjacent to the second drive component 40. Since the second drive component 40 and the second energy storage component 20 are coupled, the third position detection unit 53 can be used to detect whether the second energy storage component 20 has reached the first gate position preparation position. At the first gate position preparation position, the energy storage component completes energy storage and prepares to drive the main power supply and backup power supply for gate position switching.

[0066] The fourth position detection unit 54 is located adjacent to the first drive component 30. Since the first drive component 30 is coupled to the first energy storage component 10, the fourth position detection unit 54 can be used to detect whether the first energy storage component 10 has reached the second gate position preparation position. At the second gate position preparation position, the energy storage component completes energy storage and prepares to drive the main power supply and backup power supply for gate position switching.

[0067] This arrangement enables precise monitoring of the position and status of the energy storage components during the operation of the bidirectional energy storage device, allowing the control system to adjust the operating mode of each component based on real-time information.

[0068] In some embodiments, such as Figures 1 to 5 As shown, the first position detection unit 51, the second position detection unit 52, the third position detection unit 53, and the fourth position detection unit 54 can be microswitches.

[0069] As an example, four microswitches can be in the normally open position and switch to the normally closed position when triggered.

[0070] As another example, some of the four microswitches may be in the normally open position, while the other four microswitches may be in the normally closed position. The specific position can be determined based on the circuit connection. This disclosure is not intended to limit the scope of the invention.

[0071] In other embodiments, the first position detection unit 51, the second position detection unit 52, the third position detection unit 53, and the fourth position detection unit 54 may also be magnetic switches, proximity switches, or photoelectric sensors, etc., and this disclosure is not intended to limit them.

[0072] In some embodiments, such as Figures 2 to 5 As shown, the first drive assembly 30 includes a first pin 31, a first sector gear 32, and a first drive member 33. The first pin 31 is fixed, allowing other components connected to it to rotate around it. The first sector gear 32 includes first teeth 321. The first sector gear 32 is rotatably coupled to the first pin 31, thereby rotating around the first pin 31. Furthermore, the first sector gear 32 is coupled to the first energy storage assembly 10. When the first sector gear 32 rotates, it can drive the first energy storage assembly 10 to change position and store energy. The first drive member 33 is rotatably coupled to the first pin 31 and also coupled to the first energy storage assembly 10.

[0073] In this way, as the first sector gear 32 rotates around the first pin shaft 31, it can drive the first energy storage component 10 to store energy. After energy storage is completed, the first energy storage component 10 can drive the first driving member 33 to move, thereby driving the moving contact of the first power supply to switch between the closed position and the open position.

[0074] In some embodiments, such as Figures 2 to 5 As shown, the second drive assembly 40 includes a second pin 41, a second sector gear 42, and a second drive member 43. The second sector gear 42 is rotatably coupled to the second pin 41, thereby rotating about the second pin 41. Furthermore, the second sector gear 42 is coupled to the second energy storage assembly 20. When the second sector gear 42 rotates, it can drive the second energy storage assembly 20 to change position and store energy. The second drive member 43 is rotatably coupled to the second pin 41 and also coupled to the second energy storage assembly 20.

[0075] In this way, as the second sector gear 42 rotates around the second pin shaft 41, it can drive the second energy storage component 20 to store energy. After energy storage is completed, the second energy storage component 20 can drive the second driving member 43 to move, thereby driving the moving contact of the second power supply to switch between the closed position and the open position.

[0076] In addition, the second sector gear 42 comprises a second tooth portion 421, and the second tooth portion 421 is coupled with the first tooth portion 321, so that the actions of the two energy storage assemblies are synchronized.

[0077] In some embodiments, as shown in FIG. 1, the bidirectional energy storage device further comprises a driving gear assembly 60. The driving gear assembly 60 is engaged with the first tooth portion 321 and the second tooth portion 421, so that the first sector gear 32 and the second sector gear 42 rotate synchronously in the same direction. In this way, when the driving gear assembly 60 rotates clockwise, the first sector gear 32 and the second sector gear 42 rotate synchronously counterclockwise. When the driving gear assembly 60 rotates counterclockwise, the first sector gear 32 and the second sector gear 42 rotate synchronously clockwise. Figures 1 to 5

[0078] As an example, as shown in FIG. 1, the driving gear assembly 60 can comprise a single driving gear which is directly engaged with the first sector gear 32 and the second sector gear 42. Figures 1 to 5

[0079] In other embodiments, the driving gear assembly 60 can comprise a plurality of driving gears which are engaged with each other and then engaged with the first sector gear 32 and the second sector gear 42.

[0080] In some embodiments, as shown in FIG. 1, the first sector gear 32 is provided with a first protrusion 322 at an end away from the first tooth portion 321. The first protrusion 322 is arranged adjacent to the fourth position detection unit 54, and can trigger the fourth position detection unit 54 when the first energy storage assembly 10 is in the second brake position preparation position. In this way, when the first energy storage assembly 10 is in the second brake position preparation position, the first protrusion 322 on the first sector gear 32 abuts against the fourth position detection unit 54, and the fourth position detection unit 54 can generate a detection signal. After the control system receives the detection signal from the fourth position detection unit 54, it can determine that the first energy storage assembly 10 has completed energy storage and has the ability to switch to the second brake position. Figure 4

[0081] In some embodiments, as shown in FIG. 1, the first sector gear 32 is provided with a first protrusion 322 at an end away from the first tooth portion 321. The first protrusion 322 is arranged adjacent to the fourth position detection unit 54, and can trigger the fourth position detection unit 54 when the first energy storage assembly 10 is in the second brake position preparation position. In this way, when the first energy storage assembly 10 is in the second brake position preparation position, the first protrusion 322 on the first sector gear 32 abuts against the fourth position detection unit 54, and the fourth position detection unit 54 can generate a detection signal. After the control system receives the detection signal from the fourth position detection unit 54, it can determine that the first energy storage assembly 10 has completed energy storage and has the ability to switch to the second brake position. Figure 2 ​​​As shown, the second end of the second sector gear 42 away from the second tooth part 421 is provided with a second protrusion 422. The second protrusion 422 is arranged adjacent to the third position detection unit 53 and can trigger the third position detection unit 53 when the second energy storage assembly 20 is in the first brake position preparation position. In this way, when the second energy storage assembly 20 is in the first brake position preparation position, the second protrusion 422 on the second sector gear 42 abuts against the third position detection unit 53, and the fourth position detection unit 54 can generate a detection signal. After the control system receives the detection signal from the third position detection unit 53, it can be determined that the second energy storage assembly 20 has completed energy storage and has the ability to switch to the first brake position.

[0082] In some embodiments, as shown in Figures 6 to 9 As shown, the bidirectional energy storage device further comprises a first connecting shaft 333 and a second connecting shaft 433. The first connecting shaft 333 is coupled to the first driving member 33, and the first connecting shaft 333 can be connected with the movable contact of the first power source, thereby driving the movable contact of the first power source to switch between the open position and the closed position. The second connecting shaft 433 is coupled to the second driving member 43, and the second connecting shaft 433 can be connected with the movable contact of the second power source, thereby driving the movable contact of the second power source to switch between the open position and the closed position.

[0083] When the first driving member 33 rotates around its axis, the movable contact of the first power source will follow the movement trajectory of the first driving member 33, thereby switching between the closed position and the open position. When the second driving member 43 rotates, the movable contact of the second power source will move accordingly, thereby switching between the closed position and the open position.

[0084] In some embodiments, as shown in Figure 1 As shown, the bidirectional energy storage device can further comprise a blocking assembly 80. When the driving assembly switches the movable contact of the corresponding power source to the closed position or the open position, the blocking assembly 80 can block the further movement of the driving assembly, thereby stably connecting the circuit. When the position of the movable contact needs to be switched, the blocking assembly 80 is separated from the driving assembly to allow the driving assembly and the movable contact to operate.

[0085] In some embodiments, as shown in Figures 6 to 9 As shown, the side of the first driving member 33 away from the second driving member 43 is provided with a first recess 331, and the side of the second driving member 43 away from the first driving member 33 is provided with a second recess 431. The first recess 331 and the second recess 431 can cooperate with the corresponding blocking assembly 80, thereby limiting the first driving member 33 and the second driving member 43.

[0086] As shown in Figure 6As shown, when the corresponding blocking component 80 is moved into the first recess 331 and the second recess 431, the movement of the first driving member 33 and the second driving member 43 can be restricted. When the corresponding blocking component 80 is detached from the first recess 331 and the second recess 431, the first driving member 33 and the second driving member 43 can move.

[0087] In some embodiments, as shown in FIG. 1, the first energy storage assembly 10 includes a first connecting member 11, a pair of first driving shafts 12, and a pair of first elastic members 13. The first connecting member 11 is rotatable around a first pin shaft 31. The pair of first driving shafts 12 are respectively coupled to opposite ends of the first connecting member 11. The pair of first elastic members 13 are respectively coupled to the pair of first driving shafts 12, and the pair of first elastic members 13 are adapted to apply a force to the first connecting member 11 to rotate the first connecting member 11 around the first pin shaft 31. Figures 6 to 9

[0088] In this way, when the first connecting member 11 rotates around the first pin shaft 31, the pair of first driving shafts 12 also move, gradually compressing the pair of first elastic members 13. In this process, the pair of first elastic members 13 can accumulate elastic potential energy. When the pair of first elastic members 13 complete the storage of elastic potential energy, they can push the pair of first driving shafts 12 and the first connecting member 11 to move around the first pin shaft 31. In the process of movement, the pair of first driving shafts 12 drive the first driving member 33 to perform corresponding actions, thereby driving the movable contact of the first power source to switch between the open position and the closed position.

[0089] In some embodiments, as shown in FIG. 2, the second energy storage assembly 20 includes a second connecting member 21, a pair of second driving shafts 22, and a pair of second elastic members 23. The second connecting member 21 is rotatable around a second pin shaft 41. The pair of second driving shafts 22 are respectively coupled to opposite ends of the second connecting member 21. The pair of second elastic members 23 are respectively coupled to the pair of second driving shafts 22, and the pair of second elastic members 23 are adapted to apply a force to the second connecting member 21 to rotate the second connecting member 21 around the second pin shaft 41. Figures 6 to 9

[0090] When the second connecting member 21 rotates around the second pin shaft 41, the pair of second driving shafts 22 also move, gradually compressing the pair of second elastic members 23. In this process, the pair of second elastic members 23 accumulate elastic potential energy due to compression. When the pair of second elastic members 23 complete the storage of potential energy, they can push the pair of second driving shafts 22 and the second connecting member 21 to move around the second pin shaft 41. In the process of movement, the pair of second driving shafts 22 drive the second driving member 43 to perform corresponding actions, thereby driving the movable contact of the second power source to switch between the open position and the closed position. ​​

[0091] In some embodiments, as shown in Figures 6 to 9 The first driving member 33 is provided with a pair of first driving portions 332 on both sides. The pair of first driving portions 332 are respectively coupled to the pair of first driving shafts 12. Similarly, the second driving member 43 is also provided with a pair of second driving portions 432 on both sides, and the pair of second driving portions 432 are respectively coupled to the pair of second driving shafts 22.

[0092] When the first connecting member 11 and the pair of first driving shafts 12 rotate around the first pin shaft 31, the first driving member 33 can be driven to rotate by the pair of first driving portions 332, so as to switch the movable contact of the first power source between the open position and the closed position.

[0093] When the second connecting member 21 and the pair of second driving shafts 22 rotate around the second pin shaft 41, the second driving member 43 can be driven to rotate by the pair of second driving portions 432, so as to switch the movable contact of the second power source between the open position and the closed position.

[0094] For example, as shown in Figures 6 to 9 The pair of first driving portions 332 and the pair of second driving portions 432 can be arc-shaped protrusions. When the pair of driving shafts abut against the corresponding driving portions, the corresponding driving members can be pushed to rotate.

[0095] In other embodiments, the pair of first driving portions 332 and the pair of second driving portions 432 can also be grooves. When the pair of driving shafts are inserted into the corresponding grooves, the corresponding driving members can be pushed to rotate.

[0096] It should be understood that the pair of first driving portions 332 and the pair of second driving portions 432 can also have other shapes, and the present disclosure is not intended to be limited in this regard.

[0097] In some embodiments, as shown in Figures 2 to 5 The first sector gear 32 is provided with a pair of first sliding grooves 323 on both sides, and the pair of first driving shafts 12 are respectively located in the pair of first sliding grooves 323. The second sector gear 42 is provided with a pair of second sliding grooves 423 on both sides, and the pair of second driving shafts 22 are respectively located in the pair of second sliding grooves 423.

[0098] For example, the first sliding grooves 323 and the second sliding grooves 423 are arc-shaped sliding grooves, and the first driving shafts 12 can move in the first sliding grooves 323, and the second driving shafts 22 can move in the second sliding grooves 423.

[0099] As shown in Figure 2 When the energy storage assembly is in the first gate position preparation position, the first driving shaft 12 is located on one side of the first sliding groove 323, and the second driving shaft 22 is located on one side of the second sliding groove 423.

[0100] like Figure 3 As shown, with the positions of the first sector gear 32 and the second sector gear 42 remaining unchanged, the first drive shaft 12 moves within the corresponding first slide groove 323, and the second drive shaft 22 moves within the corresponding second slide groove 423. When the energy storage component switches to the first closed position, the first drive member 33 can drive the moving contact of the first power supply to switch to the closed position, and the second drive member 43 can drive the moving contact of the second power supply to switch to the open position.

[0101] like Figure 4 As shown, with the positions of the first drive member 33 and the second drive member 43 remaining unchanged, the first sector gear 32 and the second sector gear 42 rotate clockwise, thereby switching the energy storage component to the second gate position preparation position. Here, the first drive shaft 12 is located on the other side of the first slide groove 323, and the second drive shaft 22 is located on the other side of the second slide groove 423.

[0102] like Figure 5 As shown, with the positions of the first sector gear 32 and the second sector gear 42 remaining unchanged, the first drive shaft 12 moves within the corresponding first slide groove 323, and the second drive shaft 22 moves within the corresponding second slide groove 423. When the energy storage component switches to the second gate position, the first drive member 33 can drive the moving contact of the first power supply to switch to the open position, and the second drive member 43 can drive the moving contact of the second power supply to switch to the closed position.

[0103] In some embodiments, such as Figure 5 As shown, the width of the first groove 323 is greater than the length of the movement path of the first drive shaft 12, and the width of the second groove 423 is greater than the length of the movement path of the second drive shaft 22. In this way, when the energy storage component quickly switches from the first gate position preparation position to the first gate position or from the second gate position preparation position to the second gate position, the first drive shaft 12 will not impact the edge of the first groove 323, and the second drive shaft 22 will not impact the edge of the second groove 423, thereby improving the durability of the components. Furthermore, when the first sector gear 32 and the second sector gear 42 move in opposite directions to drive the corresponding drive shafts, the energy storage component is in the energy storage process. This process does not require high speed, and therefore will not cause impact on the edges of the first groove 323 and the second groove 423.

[0104] In some embodiments, such as Figures 10 to 13 As shown, the first energy storage component 10 also includes a first indicator 14. The first indicator 14 is coupled to a pair of first drive shafts 12, and the first indicator 14 includes a first indicator portion 141. The first indicator portion 141 is disposed adjacent to the first position detection unit 51, and can be triggered when the first energy storage component 10 is in a first gate position.

[0105] In this way, when the pair of first drive shafts 12 move, they bring the first indicator 14 to move synchronously. As the first energy storage assembly 10 switches to the first gate position, the first indication part 141 on the first indicator 14 abuts against the first position detection unit 51 arranged adjacently. When the first energy storage assembly 10 reaches the first gate position, the first indication part 141 triggers the first position detection unit 51 to generate a signal feedback to the control system. The signal can confirm that the first energy storage assembly 10 has been positioned at the first gate position, thus allowing the subsequent operation to proceed.

[0106] In some embodiments, as shown in FIG. 2, the second energy storage assembly 20 also includes a second indicator 24. The second indicator 24 is coupled to the pair of second drive shafts 22, and the second indicator 24 includes a second indication part 241. The second indication part 241 is arranged adjacently to the second position detection unit 52, and can trigger the second position detection unit 52 when the second energy storage assembly 20 is at the second gate position. Figures 10 to 13

[0107] In this way, when the pair of second drive shafts 22 move, they bring the second indicator 24 to move synchronously. As the second energy storage assembly 20 switches to the second gate position, the second indication part 241 on the second indicator 24 abuts against the second position detection unit 52 arranged adjacently. When the second energy storage assembly 20 reaches the second gate position, the second indication part 241 triggers the second position detection unit 52 to generate a signal feedback to the control system. The signal can confirm that the second energy storage assembly 20 has been positioned at the second gate position, thus allowing the subsequent operation to proceed.

[0108] In some embodiments, as shown in FIG. 2, the first position detection unit 51, the second position detection unit 52, the third position detection unit 53, and the fourth position detection unit 54 of the bidirectional energy storage device are electrically connected to the motor controller 90. Figures 14 to 17 A circuit block diagram of the position detection unit and the controller of the embodiment of the present disclosure is shown, in which the first energy storage assembly 10 is at the first gate position. Figure 14 A circuit block diagram of the position detection unit and the controller of the embodiment of the present disclosure is shown, in which the first energy storage assembly 10 is at the first gate position. Figure 15 A circuit block diagram of the position detection unit and the controller of the embodiment of the present disclosure is shown, in which the first energy storage assembly 10 is at the first gate position. Figure 16 A circuit block diagram of the position detection unit and the controller of the embodiment of the present disclosure is shown, in which the first energy storage assembly 10 is at the second gate position. Figure 17 A circuit block diagram of the position detection unit and the controller of the embodiment of the present disclosure is shown, in which the first energy storage assembly 10 is at the second gate position. In addition, the motor controller 90 is electrically connected to the motor, and the motor is connected to the drive gear assembly 60. In this way, the motor controller 90 can control the operation of the motor based on the acquired detection signals.

[0109] ​In some embodiments, as shown in Figure 18 and Figure 19 The bidirectional energy storage device further comprises a position detection assembly 70 and a fifth position detection unit 55. The position detection assembly 70 is coupled to the first driving assembly 30, can detect the position of the movable contact of the first power supply, and is adapted to switch between the first position and the second position. In the case that the position detection assembly is in the first position, the movable contact of the first power supply is in the closed position. In the case that the position detection assembly is in the second position, the movable contact of the first power supply is in the open position. The fifth position detection unit 55 is arranged adjacent to the position detection assembly 70, and can generate a detection signal for commutating the driving signal of the motor controller 90 in the case that the position detection assembly 70 is in the second position.

[0110] As shown in Figure 18 The position detection assembly 70 is coupled to the first driving member 33. In the case that the movable contact of the first power supply is in the closed position, the first driving member 33 can drive the position detection assembly 70 to be in the first position. At this point, the position detection assembly 70 is separated from the fifth position detection unit 55.

[0111] As shown in Figure 19 In the case that the movable contact of the first power supply is in the open position, the first driving member 33 can drive the position detection assembly 70 to be in the second position. At this point, the position detection assembly 70 is in contact with the fifth position detection unit 55, and the fifth position detection unit 55 can generate a detection signal for commutating the driving signal of the motor controller 90. In this way, when the motor continues to be powered, the motor moves reversely, and the energy storage assembly can be driven to switch from the second gate position to the first gate position preparation position.

[0112] In a second aspect of the present disclosure, a dual power transfer switch is provided. The dual power transfer switch comprises any one of the bidirectional energy storage devices described above.

[0113] In the dual power transfer switch of the present disclosure, the first position detection unit 51 is arranged adjacent to the first energy storage assembly 10 to detect whether the first energy storage assembly 10 is in the first gate position. The second position detection unit 52 is arranged adjacent to the second energy storage assembly 20 to detect whether the second energy storage assembly 20 is in the second gate position. The third position detection unit 53 is arranged adjacent to the second drive assembly 40 to detect whether the second energy storage assembly 20 is in the first gate position preparation position. The fourth position detection unit 54 is arranged adjacent to the first drive assembly 30 to detect whether the first energy storage assembly 10 is in the second gate position preparation position. With such an arrangement, during the operation of the bidirectional energy storage assembly, the position state of the energy storage assembly is accurately detected by the first position detection unit 51, the second position detection unit 52, the third position detection unit 53 and the fourth position detection unit 54, the action of the energy storage device can be intelligently managed, and thus the transfer efficiency and reliability of the bidirectional energy storage device are improved.

[0114] The above has described various embodiments of the present disclosure, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those skilled in the art without departing from the scope and spirit of the described embodiments.
