However, the elements in the conventional dual power controller are complex in connection with each other and large in size. Embodiments of the present disclosure provide a dual power controller 100 to at least partially solve the above problems. In the following, the dual power controller 100 will be described in detail in conjunction with the accompanying drawings. Figures 1 to 4 The principles of the present disclosure are described.

[0035] Figure 1 An exploded view of the dual power controller 100 according to some embodiments of the present disclosure is shown, wherein the plurality of expansion assemblies 8 is not shown. Figure 2 A structural schematic view of the dual power controller 100 according to some embodiments of the present disclosure is shown. Figure 3 A structural schematic view of the dual power controller 100 is shown along another perspective. As shown in the figure, the dual power controller 100 includes a first connecting member 61, a second connecting member 62, a display assembly 7, and a plurality of expansion assemblies 8. Figure 2 A structural schematic view of the dual power controller 100 is shown along another perspective. As shown in the figure, the dual power controller 100 includes a first connecting member 61, a second connecting member 62, a display assembly 7, and a plurality of expansion assemblies 8. Figures 1 to 3As shown, the dual power supply controller 100 described herein generally includes a base 1, a cover plate 2, a driving circuit board 3, a control circuit board 4, a power supply circuit board 5, a first connecting member 61, a second connecting member 62, a display assembly 7, and a plurality of extension assemblies 8. The cover plate 2 can be disposed on the base 1 and can enclose a mounting space with the base 1, and the driving circuit board 3, the control circuit board 4, the power supply circuit board 5, the first connecting member 61, and the second connecting member 62 are located in the mounting space. The display assembly 7 can be located outside the cover plate 2. The plurality of extension assemblies 8 can pass through the cover plate 2 and be located in the mounting space.

[0036] With reference to Figure 1 In some embodiments, the driving circuit board 3 is disposed in the mounting space adjacent to the base 1. The control circuit board 4 mainly functions as control, and the control circuit board 4 is disposed in the mounting space adjacent to the cover plate 2. The driving circuit board 3 is electrically connected to the control circuit board 4. The power supply circuit board 5 is disposed in the mounting space adjacent to the same end of the driving circuit board 3 and the control circuit board 4, and the power supply circuit board 5 is electrically connected to the control circuit board 4.

[0037] According to embodiments of the present disclosure, since the driving circuit board 3 is disposed adjacent to the base 1, the control circuit board 4 is disposed adjacent to the cover plate 2, and the power supply circuit board 5 is disposed adjacent to the same end of the driving circuit board 3 and the control circuit board 4, the dual power supply controller 100 has a compact structure and a small size. In addition, since the driving circuit board 3 is electrically connected to the control circuit board 4, and the power supply circuit board 5 is electrically connected to the control circuit board 4, the elements of the dual power supply controller 100 are simply connected to each other.

[0038] With reference to Figure 1 Further, the driving circuit board 3 can be disposed parallel to the control circuit board 4. In this way, the size of the dual power supply controller 100 can be further reduced. In addition, the base 1 can be installed on the guide rail by clamping, so that the dual power supply controller 100 is convenient and flexible to install and disassemble.

[0039] With reference to Figure 1 In some embodiments, the driving circuit board 3 can include a plurality of relays 31. The plurality of relays 31 can be disposed on the side of the driving circuit board 3 facing the control circuit board 4. In addition, the plurality of relays 31 can each include an insulating shell 311, for example, the insulating shell 311 can include a plastic shell. The insulating shell 311 of the plurality of relays 31 is each spaced apart from the control circuit board 4. In this way, the driving circuit board 3 and the control circuit board 4 in the dual power supply controller 100 meet the insulation requirements, and also help to reduce the height of the dual power supply controller 100, thereby reducing the size and volume of the dual power supply controller 100.

[0040] With reference to Figure 1In some embodiments, the base 1 can include an insulation plate 11. The insulation plate 11 can divide the installation space into a first installation space 101 and a second installation space 102. The power supply circuit board 5 can be located in the first installation space 101, and the control circuit board 4 and the driving circuit board 3 can be disposed in the second installation space 102. Thus, the insulation plate 11 can meet the insulation requirement between the power supply circuit board 5 and the control circuit board 4, and facilitate reducing the length of the dual power supply controller 100, thereby reducing the size and volume of the dual power supply controller 100.

[0041] With reference back to Figures 1 to 2 In some embodiments, the control circuit board 4 can include a normal power supply interface 41 and a backup power supply interface 42 adjacent to the normal power supply interface 41. Thus, the control circuit board 4 can be connected to the normal power supply through the normal power supply interface 41, and the control circuit board 4 can also be connected to the backup power supply through the backup power supply interface 42.

[0042] With reference back to Figures 1 to 2 Further, the base 1 and the cover plate 2 can be provided with an opening 22 at the connection position, and the normal power supply interface 41 and the backup power supply interface 42 can respectively pass through the opening 22 to facilitate connection with the normal power supply and the backup power supply. Of course, the opening 22 can also be provided on the cover plate 2, which is not limited here.

[0043] With reference back to Figure 1 In some embodiments, the control circuit board 4 can also include a first wiring member 43 and a pair of second wiring members 44. The power supply circuit board 5 can include a third wiring member 51 and a pair of fourth wiring members 52. The pair of second wiring members 44 are each electrically connected to a corresponding fourth wiring member 52, and the third wiring member 51 is electrically connected to the first wiring member 43. The power supply circuit board 5 can be integrated with a step-down circuit. Thus, the power supply circuit board 5 can convert the alternating voltage of the normal power supply and the backup power supply into a direct current output voltage of, for example, 24V, and transmit the direct current output voltage of 24V to the control circuit board 4 through the third wiring member 51 and the first wiring member 43. The control circuit board 4 can be integrated with a plurality of circuits, such as a secondary power supply circuit, to convert the direct current output voltage of 24V into a direct current output voltage of, for example, 3.3V, thereby meeting the power supply requirements of different specifications. In addition, compared with a power frequency transformer, the power supply circuit board 5 according to the embodiments of the present disclosure has a reduced volume to meet the small volume design of the dual power supply controller 100.

[0044] With reference back to Figure 1 and Figure 3Further, the control circuit board 4 can further include a second extension interface 48, which can be externally connected to a DC power supply, for example, 24V, to supply power to the internal elements of the dual power controller 100. The second extension interface 48 can be adjacent to the first terminal 43 to facilitate the connection of the 24V DC voltage at the second extension interface 48 with the 24V DC voltage at the first terminal 43. In addition, one end of a first connecting element 61 can be connected to the drive circuit board 3, and the other end of the first connecting element 61 can be connected to the control circuit board 4. The first connecting element 61 serves to connect the drive circuit board 3 and the control circuit board 4. Thus, the coils of some of the relays 31 in the drive circuit board 3 can be supplied with 24V DC voltage.

[0045] With continued reference to Figure 1 In some embodiments, the control circuit board 4 can further include a pair of fifth terminals 45. The drive circuit board 3 can further include a pair of sixth terminals 32, and each of the pair of fifth terminals 45 can be electrically connected to a corresponding sixth terminal 32. Thus, the AC voltage of the normal power supply and the backup power supply can be transmitted to the pair of sixth terminals 32 through the pair of fifth terminals 45. The control circuit board 4 can be integrated with a pair of detection circuits to detect the status of the normal power supply and the backup power supply, respectively. In the case where the control circuit board 4 detects the status of the normal power supply and the backup power supply, respectively, the control circuit in the control circuit board 4 can control another part of the relays 31 in the drive circuit board 3 to select one of the normal power supply and the backup power supply to be turned on. It can be understood that the power supply with a better status can be selected.

[0046] With continued reference to Figures 1 to 2 Further, the control circuit board 4 can further include a pair of circuit breaker control interfaces 46, which can pass through the cover plate 2. The drive circuit board 3 can further include a pair of circuit breaker drive interfaces 33, which can pass through the base 1. One of the pair of circuit breaker control interfaces 46 and one of the pair of circuit breaker drive interfaces 33 are electrically connected to the first circuit breaker 201. The other of the pair of circuit breaker control interfaces 46 and the other of the pair of circuit breaker drive interfaces 33 are electrically connected to the second circuit breaker 202.

[0047] With the above configuration, the dual power controller 100 is simple and reliable in wiring with the first circuit breaker 201 and the second circuit breaker 202 respectively. In addition, the control circuit board 4 can be electrically connected to the first circuit breaker 201 and the second circuit breaker 202 through the circuit breaker control interface 46, and the control circuit board 4 can be integrated with a contact state detection circuit to detect the state of the contacts in the first circuit breaker 201 and the second circuit breaker 202, so as to determine the opening and closing state of the circuit breaker and the like. In addition, the drive circuit board 3 can be electrically connected to the first circuit breaker 201 and the second circuit breaker 202 through the circuit breaker drive interface 33, so as to select one of the normal power supply and the standby power supply to supply power to the elements in the first circuit breaker 201 and the second circuit breaker 202. For example, the circuit breaker drive interface 33 can include a closing coil interface, an opening coil interface, and a motor interface, and the like, so as to supply power to the closing coil, the opening coil, and the motor, thereby realizing the opening and closing operation of the circuit breaker.

[0048] With reference to Figure 2 Further, the pair of circuit breaker control interfaces 46 can be adjacent to the standby power supply interface 42, and the pair of circuit breaker control interfaces 46, the standby power supply interface 42, and the normal power supply interface 41 are located in the same row. In addition, the pair of circuit breaker drive interfaces 33 are located in another row. In this way, the interfaces are arranged above and below each other, which facilitates wiring.

[0049] With reference to Figures 1 to 3 In some embodiments, the cover plate 2 can include a plurality of mounting holes 21. The plurality of expansion assemblies 8 can be respectively limited in the corresponding mounting holes 21, and the plurality of expansion assemblies 8 can be respectively electrically connected to the drive circuit board 3.

[0050] With reference to Figure 1 and Figure 3 In some embodiments, the control circuit board 4 can further include a first expansion interface 47. The first expansion interface 47 can pass through the cover plate 2. The first expansion interface 47 can be connected to an expansion screen or the like, so as to realize cabinet door display.

[0051] With reference to Figure 1 In some embodiments, the display assembly 7 can be arranged on the side of the cover plate 2 away from the base 1, and the display assembly 7 is used to display state information. One end of the second connecting piece 62 can be connected to the control circuit board 4, and the other end of the second connecting piece 62 can pass through the cover plate 2 and be connected to the display assembly 7, and the second connecting piece 62 serves as an electrical connection between the display assembly 7 and the control circuit board 4.
