[0035] In order to make the technical problems to be solved by the present application, the technical solutions and beneficial effects more clearly, the following will be combined with the drawings needed to be used in the embodiments or prior art description will be briefly introduced. Obviously, the drawings in the following description are only some embodiments of the present application, and other drawings can be obtained by those skilled in the art without creative labor. Figures 1 to 6The application will be further described in detail with reference to the embodiments. It should be understood that the specific embodiments described herein are merely intended to explain the application and are not intended to limit the application.

[0036] It should be noted that when an element is referred to as being "fixed" or "set" on another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or indirectly connected to the other element.

[0037] It should be understood that the terms "length", "width", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only used to facilitate the description of the application and simplify the description, and therefore cannot be understood as indicating or implying that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the application.

[0038] In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the application, the meaning of "multiple" is two or more, the meaning of "multiple groups" is two groups or more, the meaning of "multiple pieces" is two pieces or more, and the meaning of "several" is one or more, unless otherwise specifically limited.

[0039] With the continuous improvement of the automation degree of modern industrial facilities, the application of power distribution devices in power and process control systems is increasingly widespread. The power distribution device includes a power distribution panel and an electric actuator plugged into the power distribution panel. The power distribution panel, also known as a power distribution cabinet, is a device for concentrating, switching, and distributing electric energy. The electric actuator can operate the switch on the power distribution panel to open and close the switch. In some complex power distribution systems, the electric actuator can control the related devices (such as intelligent circuit breakers and contactors) on the power distribution panel, thereby adjusting and distributing the current of different branches. For example, in a large data center, the electric actuator can adjust the current of the corresponding branch according to the load demand of different server cabinets, to ensure that the power supply to each cabinet is balanced and stable.

[0040] The electric actuator generally comprises a motor driving module, a control signal receiving and processing module, a control circuit module and a position feedback mechanism module, which are connected with each other to realize various functions of the electric actuator. For example, the relay in the control circuit module can be used to control the start, stop and forward / reverse rotation of the motor. When receiving an external control signal, the relay will close or open the corresponding circuit according to the instruction of the signal, thereby controlling the operation of the motor. In some complex control circuits of electric actuators, multiple relays cooperate with each other to realize various control logics.

[0041] However, the existing distribution panel often has a large number of interfaces, and it is easy to insert the electric actuator into the wrong interface. Such misoperation can easily cause device function disorder, and even cause electrical safety accidents, threatening the production safety and stable operation of the equipment.

[0042] Based on this, the embodiments of the present application provide an electric actuator, a distribution panel and a distribution device to solve the above problems.

[0043] Reference Figures 1 to 4 The embodiments of the present application first provide an electric actuator 1 applied to on-off operation of the switch of the distribution panel 2. The electric actuator 1 comprises a housing assembly, a lock assembly 104, a first identifier 103 and a first controller 112. One side of the housing assembly is provided with a second interface 102 adapted to the first interface 201 of the distribution panel 2. The lock assembly 104 is installed on the housing assembly and is used to lock the second interface 102 to restrict the insertion of the second interface 102 into the first interface 201. The first identifier 103 is installed on one side of the housing assembly and is used to identify the identification information of the first identification member 202 corresponding to the first interface 201 of the distribution panel 2. The first controller 112 is installed on the housing assembly and is in communication connection with the lock assembly 104 and the first identifier 103. The first controller 112 is used to receive the identification information identified by the first identifier 103 and control the locking and unlocking of the lock assembly 104 according to the identification information identified by the first identifier 103.

[0044] It should be noted that before the first identifier 103 successfully identifies the first identification member 202, the lock assembly 104 locks the second interface 102 to restrict the insertion of the second interface 102 into the first interface 201. After the first identifier 103 successfully identifies the first identification member 202, the lock assembly 104 is unlocked to open the second interface 102, so that the second interface 102 can be inserted into the first interface 201.

[0045] It should be noted that the first controller 112 is in communication connection with the lock assembly 104 and the first identifier 103. The communication connection can mean that a channel or link capable of information transmission and interaction is established between different electronic components, systems or networks. Such connection can be wired connection or wireless connection. The wired connection can be twisted pair connection, optical fiber connection or coaxial cable connection. Taking the twisted pair connection as an example, the most common twisted pair in life is Ethernet network cable, which is composed of multiple twisted pairs and can be used for local area network connection. It has the characteristics of low cost and stable transmission, and is suitable for fixed position device connection. For example, the first controller 112 and the first identifier 103 can be connected by twisted pair, and the signal between the first controller 112 and the first identifier 103 is transmitted through the twisted pair. The wireless connection can be Wi-Fi connection, Bluetooth connection or mobile network connection. Taking the Bluetooth connection as an example, Bluetooth connection is a short-range wireless communication technology commonly used in life to connect mobile devices, earphones, keyboards, mice and other devices. Bluetooth connection has the characteristics of low power consumption, low cost and convenience. For example, the first controller 112 and the first identifier 103 can be connected by Bluetooth, and the information between the first controller 112 and the first identifier 103 is transmitted by Bluetooth transmission. In industrial production, wired and wireless communication connection technology is used to realize data transmission and control instruction transmission between devices. For example, various automatic devices are connected through industrial Ethernet to realize real-time monitoring and optimization of the production process. Wireless sensor networks are used to monitor the production environment and device status to improve production efficiency and safety.

[0046] It should be noted that the first interface 201 of the distribution panel 2 can be provided with multiple first interfaces 201, and the first identifier 202 can be provided one by one corresponding to each first interface 201. Before the electric actuator 1 is plugged into the distribution panel 2, i.e. in the initial state, the lock assembly 104 can be in the locked position. The information corresponding to the first interface 201 can be stored in the electric actuator 1 in advance. After the electric actuator 1 scans the first identifier 202 to obtain the identification information of the corresponding first interface 201, the information can be compared with the information stored in advance. If the information comparison is successful, it can be determined that this first interface 201 is the correct first interface 201 for plugging in the electric actuator 1. At this time, the first identifier 103 successfully identifies the first identifier 202, and the first controller 112 of the electric actuator 1 can unlock the lock assembly 104, so that the electric actuator 1 can be inserted into the first interface 201 to realize connection with the distribution panel 2. If the identification information of the first interface 201 obtained by the electric actuator 1 scanning the first identifier 202 does not match the information stored in advance, it can be considered that the first identifier 103 cannot successfully identify the first identifier 202. At this time, the first controller 112 will not control the lock assembly 104 to be unlocked.

[0047] Of course, the information corresponding to the first interface 201 can also not be stored in advance in the electric actuator 1. The identification information of the first identification member 202 corresponding to the first interface 201 can contain a command to unlock the lock assembly 104 of the corresponding electric actuator 1, and the command is only valid for this electric actuator 1. That is, the unlock command of each first interface 201 on the switchboard 2 is not the same. The switchboard 2 sets the corresponding unlock command for each electric actuator 1 one by one. For example, assume that the switchboard 2 has two first interfaces 201, which can be referred to as A interface and B interface respectively. The electric actuator 1 is correspondingly provided with two, which can be referred to as C head and D head respectively. Among them, the C head corresponds to the A interface, and the D head corresponds to the B interface. Therefore, the identification information of the first identification member 202 corresponding to the A interface can contain a command to unlock the lock assembly 104 of the C head, and the first controller 112 of the C head can recognize the unlock command. The identification information of the first identification member 202 corresponding to the B interface can contain a command to unlock the lock assembly 104 of the D head, and the first controller 112 of the D head can recognize the unlock command. The first controller 112 of the C head cannot recognize the unlock command contained in the B interface, and the first controller 112 of the D head cannot recognize the unlock command contained in the A interface. When the first identifier 103 of the C head recognizes the information of the A interface, and the first controller 112 of the C head receives the unlock command contained in the information of the A interface, the first controller 112 of the C head can recognize the unlock information and unlock the lock assembly 104 of the C head. At this time, the second interface 102 of the C head can be inserted into the A interface. When the first identifier 103 of the C head recognizes the information of the B interface, and the first controller 112 of the C head receives the unlock command contained in the information of the B interface, the first controller 112 of the C head cannot recognize the unlock information. At this time, the first controller 112 of the C head cannot successfully recognize the first identification member 202 corresponding to the B interface, and cannot unlock the lock assembly 104 of the C head. At this time, the C head cannot be inserted into the B interface.

[0048] The electric actuator 1 of the embodiment of the present application is provided with the first recognizer 103 for identifying the identification information of the first identification member 202. In this way, the electric actuator 1 can identify the information of the first interface 201, so that the electric actuator 1 can be correctly inserted into the corresponding first interface 201, thereby improving the stability of the electric actuator 1. In addition, the electric actuator 1 is provided with the lock assembly 104 for limiting the insertion of the second interface 102 into the first interface 201. When the electric actuator 1 does not identify the first interface 201 corresponding thereto, the lock assembly 104 can be in a closed state, so that the second interface 102 of the electric actuator 1 cannot be inserted into the first interface 201. When the electric actuator 1 obtains the information of the first interface 201 corresponding thereto, the first controller 112 of the electric actuator 1 can unlock the lock assembly 104, so that the second interface 102 of the electric actuator 1 can be inserted into the first interface 201. In this way, the correct connection of the electric actuator 1 and the first interface 201 can be achieved. Through the above arrangement, before the electric actuator 1 identifies the information of the first interface 201, the lock assembly 104 is in a locked position, and the second interface 102 of the electric actuator 1 is locked by the lock assembly 104. In this way, the electric actuator 1 cannot be inserted into the first interface 201, thereby reducing the probability of incorrect insertion of the electric actuator 1. After the electric actuator 1 identifies the information of the corresponding first interface 201, the first controller 112 of the electric actuator 1 can unlock the lock assembly 104. In this way, the second interface 102 of the electric actuator 1 can be inserted into the first interface 201, thereby improving the correctness of the insertion of the electric actuator 1 and the first interface 201, and helping to improve the stability of the equipment operation.

[0049] Referring to Figure 4 and Figure 6 In some embodiments, the electric actuator 1 further comprises a first wireless connection module 111 mounted on the housing assembly. The first wireless connection module 111 is in communication connection with the first controller 112. The first controller 112 is further configured to start the first wireless connection module 111 after the second interface 102 is connected with the first interface 201. The first wireless connection module 111 is configured to be in communication connection with the second wireless communication module 305 of the terminal device 3, so that the electric actuator 1 can be electrically operated through the terminal device 3.

[0050] It should be noted that the electrical operation can refer to a series of activities such as control, adjustment, maintenance and fault handling of the electrical equipment, for example, the terminal device 3 can start and stop the components in the electric actuator 1, so that the electric actuator 1 can control the conduction and isolation of the circuit in the switchboard 2. For example, a relay can be provided in the electric actuator 1, and the terminal device 3 can control the opening and closing of the relay; for example, the terminal device 3 can monitor the working state of the electric actuator 1 in real time, such as monitoring voltage, current, power, frequency and other parameters, to determine whether the electric actuator 1 is working normally. In this way, when abnormal fluctuations are found, measures can be taken in time to reduce the probability of accidents.

[0051] It should be noted that the terminal device 3 can be a mobile phone, a tablet, a computer, a remote control, an interactive machine or the like. The terminal device 3 can have a second wireless connection module 305, and the second wireless module 305 can be used to communicate with the first wireless connection module 111. For example, referring to Figure 6 The terminal device 3 can include a housing 301 and a touch screen 302 connected to the housing 301. The touch screen 302 can display information, and the worker can click the touch screen 302 to perform electrical operation on the electric actuator 1.

[0052] The terminal device 3 and the electric actuator 1 are communicatively connected, and the terminal device 3 can be used to perform electrical operation on the electric actuator 1, which can facilitate operation. The first wireless connection module 111 is communicatively connected with the first controller 112, and after the second interface 102 is plugged with the first interface 201, the first controller 112 can start the first wireless connection module 111. In this way, the first wireless connection module 111 can be started without manual operation, which can reduce the amount of manual work and help improve work efficiency.

[0053] In some embodiments, the electric actuator 1 further includes a second identification member 110 disposed outside the housing assembly, and the second identification member 110 is used to be identified by the terminal device 3 to enable the second wireless connection module 305 to start and communicate with the first wireless connection module 111.

[0054] It should be noted that the terminal device 3 can be provided with a second identifier 303 for identifying the second identification member 110. The terminal device 3 identifies the second identification member 110 through the second identifier 303. For example, the type of the second identification member 110 can be selected according to the type of the second identifier 303. For example, when the second identifier 303 is a scanning camera, the second identification member 110 can be a two-dimensional code or a bar code. When the second identifier 303 is an NFC identifier, the second identification member 110 can be an NFC chip.

[0055] The second identifier 110 is arranged on the electric actuator 1, and the electric actuator 1 can be recognized by the terminal device 3. Thus, the terminal device 3 can obtain information corresponding to the electric actuator 1, which helps to improve the accuracy of electrical operation. When the terminal device 3 recognizes the electric actuator 1, the second wireless connection module 305 of the terminal device 3 can be automatically turned on and connected with the first wireless connection module 111. Thus, the labor workload can be reduced, and the work efficiency can be improved.

[0056] In some embodiments, the second identifier 110 is an NFC chip, and the second recognizer 303 is an NFC recognizer.

[0057] The second identifier 110 is arranged as an NFC chip, and the second recognizer 303 is arranged as an NFC recognizer. The electric actuator 1 and the terminal device 3 can be recognized by using NFC (Near Field Communication) technology. The NFC technology can realize non-contact communication. When used, the second recognizer 303 of the terminal device 3 only needs to be close to or touch the second identifier 110 of the electric actuator 1, and data transmission or interactive operation can be completed. No complex pairing, connection and other steps are required. In addition, the NFC technology can quickly establish a connection and transmit data, and can complete information reading and interaction in a short time. Thus, the recognition speed between the terminal device 3 and the electric actuator 1 can be improved. In addition, the communication distance of the NFC technology is short, and it belongs to near field communication technology. The short-distance communication feature makes the staff need to approach the electric actuator 1 and paste the terminal device 3 close to the electric actuator 1, so that the terminal device 3 can recognize the information of the electric actuator 1. Thus, the probability of misoperation due to misreading of the electric actuator 1 can be reduced, and the safety of the work can be improved.

[0058] In other embodiments, the second recognizer 303 can also be a scanning camera, and the second identifier 110 can be a two-dimensional code or a bar code. The second recognizer 303 can scan and obtain the information of the second identifier 110. In still other embodiments, the second recognizer 303 can also be an RFID (Radio Frequency Identification) recognizer, and the second identifier 110 can be an RFID tag. When the RFID recognizer is close to the RFID tag, the RFID recognizer can recognize the information of the RFID tag.

[0059] In some embodiments, the first wireless connection module 111 and the second wireless connection module 305 are both Bluetooth connection modules. Thus, the electric actuator 1 and the terminal device 3 can be connected by using Bluetooth technology.

[0060] Bluetooth technology is a short-range wireless communication technology, which aims to establish a short-range wireless communication environment for fixed devices and mobile devices. Thus, the wireless connection between the electric actuator 1 and the terminal device 3 is free from the constraints of wired connection, facilitating the operation. In addition, the Bluetooth connection has strong anti-interference ability, which can improve the stability of the connection between the electric actuator 1 and the terminal device 3.

[0061] In some embodiments, the second identifier 110 of the electric actuator 1 is an NFC chip, and the second identifier 303 of the terminal device 3 is an NFC identifier. After the second identifier 303 successfully identifies the second identifier 110, the second identifier 303 can send information to the second wireless connection module 305 (or the second controller 304 in the terminal device 3), thereby starting the second wireless connection module 305. Correspondingly, after the second identifier 110 is identified, the second identifier 110 can send information to the first wireless connection module 111 (or the first controller 112 in the electric actuator 1), thereby starting the first wireless connection module 111. When the first wireless connection module 111 and the second wireless connection module 305 are both started, the first wireless connection module 111 can be in communication with the second wireless connection module 305, so that the electric actuator 1 and the terminal device 3 form a communication connection. Thus, the terminal device 3 can be used to electrically operate the electric actuator 1.

[0062] In some embodiments, a plurality of electric actuators 1 are provided, and the second wireless connection module 305 is in communication with the first wireless connection module 111 of one of the electric actuators 1. Thus, the terminal device 3 is connected with only one electric actuator 1 at a time, and the terminal device 3 can be used to individually operate one of the plurality of electric actuators 1. After the operation is completed, the connection between the terminal device 3 and the electric actuator 1 can be disconnected, and then the terminal device 3 is connected with another electric actuator 1 for individual operation. In this way, the probability of misoperation can be reduced.

[0063] In other embodiments, the terminal device 3 can also be connected with a plurality of electric actuators 1 at the same time. Thus, the terminal device 3 can be used to electrically operate the plurality of electric actuators 1 at the same time, thereby improving the efficiency of the operation.

[0064] In some embodiments, the terminal device 3 and the electric actuator 1 are connected by Bluetooth. The frequency band used by the Bluetooth connection is 2.4 GHz. This frequency band is divided into 79 channels, and the bandwidth of each channel is 1 MHz. Such channel division allows multiple devices to communicate on the same frequency band and effectively avoids channel conflicts. Thus, one terminal device 3 can be connected with multiple electric actuators 1.

[0065] In some embodiments, when the electric actuator 1 and the terminal device 3 are disconnected due to a long distance, within a preset time, the staff moves the terminal device 3 close to the electric actuator 1, and the terminal device 3 can directly re-establish a connection with the electric actuator 1; if the connection is not re-established within the preset time, the first wireless connection module 111 of the electric actuator 1 can be automatically closed, at this time, the second wireless connection module 305 of the terminal device 3 can be automatically closed or kept in an open state, when it is necessary to re-establish a connection between the terminal device 3 and the electric actuator 1, the second identifier 303 of the terminal device 3 can be used to re-identify the second identification element 110 of the electric actuator 1, so as to start the second wireless connection module 305 of the electric actuator 1 and the second wireless connection module 305 of the terminal device 3, and realize the communication connection between the terminal device 3 and the electric actuator 1.

[0066] In some embodiments, two electric actuators 1 are provided, which can be respectively denoted as C head and D head. In some embodiments, the terminal device 3 is connected with only one electric actuator 1 at a time, then the second identifier 303 of the terminal device 3 can first identify the second identification element 110 of the C head, then the terminal device 3 can be in communication connection with the C head, the terminal device 3 can perform electrical operation on the C head, after the operation is completed, the communication connection between the terminal device 3 and the C head can be disconnected, and then the second identifier 303 of the terminal device 3 identifies the second identification element 110 of the D head, so that the terminal device 3 is in communication connection with the D head, at this time, the terminal device 3 can perform electrical operation on the D head. In other embodiments, the terminal device 3 can be connected with multiple electric actuators 1 at the same time, then the second identifier 303 of the terminal device 3 can first identify the second identification element 110 of the C head, then the terminal device 3 can be in communication connection with the C head, while the terminal device 3 and the C head are in communication connection, the second identifier 303 of the terminal device 3 identifies the second identification element 110 of the D head, so that the terminal device 3 is in communication connection with the D head, in this way, the terminal device 3 can perform electrical operation on the C head and the D head at the same time.

[0067] In some embodiments, the first identifier 103 is a scanner, and the first identification element 202 has an identification code, and the scanner is used to scan the identification part.

[0068] It should be noted that the identification code can be a two-dimensional code, a bar code, an OCR (Optical Character Recognition) code, etc., and the information of the electric actuator 1 can be stored in these codes, and the first identifier 103 obtains the information of the electric actuator 1 by scanning these codes.

[0069] The first identifier 103 is arranged as a scanner, and the first identifier 103 can acquire information of the first interface 201 by scanning, so that the first identifier 202 can not need to be connected with the circuit structure, and thus the structure of the switchboard 2 can be simplified; the electric actuator 1 can determine whether the first interface 201 is the interface to be plugged according to the acquired information, so as to control locking and unlocking of the lock assembly 104, so that the electric actuator 1 can be inserted into the correct first interface 201, and the safety of operation is improved.

[0070] In other embodiments, the first identifier 202 can also be a structural member with a specific shape, and the first identifier 103 can identify by scanning the shape profile of the first identifier 202, for example, the shape profile of the first identifier 202 can be circular, square, triangular, pentagonal, free shape, etc., and different shape profiles of the identifier can store different information, and the first identifier 103 can acquire information of the corresponding electric actuator 1 through the corresponding shape profile of the first identifier 202.

[0071] In still other embodiments, the first identifier 103 can also be an NFC identifier, an RFID identifier, etc., and the first identifier 202 can be correspondingly arranged as an NFC chip, an RFID chip, etc.

[0072] With reference to Figure 2 In some embodiments, the second interface 102 and the first identifier 103 are located on the same side of the electric actuator 1.

[0073] For example, the electric actuator 1 has a first side 101, and when the electric actuator 1 is connected with the switchboard 2, the first side 101 faces the switchboard 2, and the second interface 102 and the first identifier 103 are arranged on the first side 101.

[0074] The second interface 102 and the first identifier 103 are arranged on the same side of the housing assembly, and when the first identifier 103 identifies the information of the first identifier 202, the second interface 102 and the first identifier 103 both face the switchboard 2, and when the lock assembly 104 of the electric actuator 1 is unlocked, the second interface 102 can be plugged into the first interface 201 without needing to change the direction of the electric actuator 1, so that the operation can be facilitated, and the efficiency of operation is improved.

[0075] With reference to Figure 1In some embodiments, the electric actuator 1 further comprises a speaker 106 mounted on the housing assembly, the speaker 106 is communicatively connected with the first controller 112, and the speaker 106 is configured to broadcast sound instructions. For example, when the first identification member 202 recognized by the electric actuator 1 belongs to the first interface 201 corresponding to the electric actuator 1, the first controller 112 can broadcast a sound instruction through the speaker 106 to instruct the worker to insert the electric actuator 1 into the first interface 201, and when the first identification member 202 recognized by the electric actuator 1 does not belong to the first interface 201 corresponding to the electric actuator 1, the first controller 112 can broadcast another sound instruction through the speaker 106 to instruct the worker to match the error. In this way, the speaker 106 can assist the worker to insert the electric actuator 1 into the correct first interface 201, and help to improve the work efficiency.

[0076] With reference to Figure 1 In some embodiments, the electric actuator 1 further comprises a display screen 105 mounted on the housing assembly, the display screen 105 is communicatively connected with the first controller 112, and the display screen 105 is configured to display picture instructions. For example, when the first identification member 202 recognized by the electric actuator 1 belongs to the first interface 201 corresponding to the electric actuator 1, the first controller 112 can present a picture instruction through the display screen 105 to instruct the worker to insert the electric actuator 1 into the first interface 201, and when the first identification member 202 recognized by the electric actuator 1 does not belong to the first interface 201 corresponding to the electric actuator 1, the first controller 112 can present another picture instruction through the display screen 105 to instruct the worker to match the error. In this way, the display screen 105 can assist the worker to insert the electric actuator 1 into the correct first interface 201, and help to improve the work efficiency.

[0077] With reference to Figure 5The lock assembly 104 comprises a locking piece 1042 mounted on the housing assembly and a driving piece 1041 connected with the locking piece 1042, and the driving piece 1041 is further communicatively connected with the first controller 112. The driving piece 1041 is configured to drive the locking piece 1042 to move according to the control signal of the first controller 112, so as to switch the locking piece 1042 between the locking position and the unlocking position. When the locking piece 1042 is in the locking position, the locking piece 1042 can abut against the switchboard 2 during the process of inserting the second interface 102 into the first interface 201, so as to limit the insertion of the second interface 102 into the first interface 201, thereby locking the second interface 102. When the locking piece 1042 is in the unlocking position, the locking piece 1042 does not abut against the switchboard 2 during the process of inserting the second interface 102 into the first interface 201, so as to allow the insertion of the second interface 102 into the first interface 201, thereby unlocking the second interface 102. That is, when the locking piece 1042 is in the locking position, the locking piece 1042 is configured to abut against the switchboard 2 to lock the second interface 102, thereby limiting the insertion of the second interface 102 into the first interface 201. When the locking piece 1042 is in the unlocking position, the lock assembly 104 opens the second interface 102, so that the second interface 102 can be inserted into the first interface 201, thereby connecting the electric actuator 1 with the switchboard 2. When the locking piece 1042 is in the locking position, if the first interface 201 is inserted with the second interface 102, the locking piece 1042 will abut against the first interface 201, thereby blocking the further insertion of the first interface 201 with the second interface 102. The locking piece 1042 and the first interface 201 abut against each other in a contact manner to block the further insertion of the first interface 201 with the second interface 102, which can improve the reliability of the lock assembly 104, thereby reducing the possibility of the electric actuator 1 being incorrectly inserted with the first interface 201.

[0078] In some embodiments, when the locking piece 1042 is in the locking position, at least part of the locking piece 1042 is located in the second interface 102, so as to abut against the first interface 201 during the process of inserting the second interface 102 into the first interface 201, thereby locking the second interface 102. When the locking piece 1042 is in the unlocking position, the locking piece 1042 is entirely located outside the second interface 102 and does not abut against the switchboard 2 during the process of inserting the second interface 102 into the first interface 201, thereby unlocking the second interface 102.

[0079] Referring to Figure 5 (a) in FIG. 1, Figure 5 (b) in FIG. 2, Figure 5 (c) in FIG. 3, and Figure 5In some embodiments, (d) of the embodiment, the locking member 1042 is slidably disposed on the housing assembly of the electric actuator 1, and the driving member 1041 drives the locking member 1042 to slide relative to the housing assembly of the electric actuator 1. When the locking member 1042 is in the locked position, the locking member 1042 moves to such that at least a portion of the locking member 1042 is located within the second interface 102, and when the locking member 1042 is in the unlocked position, the locking member 1042 moves to such that the entire locking member is located outside the second interface 102.

[0080] Reference Figure 5 (a) and Figure 5 In (b) of the embodiments, in some embodiments, the locking assembly 104 may be disposed inside the housing assembly of the electric actuator 1, initially, referring to Figure 5 In (a), the lock assembly 104 is in the locked position, and the locking member 1042 can be fully inserted into the second interface 102, or only a portion of the locking member 1042 can be inserted into the second interface 102. In this case, if the first interface 201 is plugged into the second interface 102, the locking member 1042 will interfere with the first interface 201, preventing further plugging between the first interface 201 and the second interface 102. When the first identifier 103 of the electric actuator 1 identifies the identification information of the first identifier 202 of the distribution panel 2, the first controller 112 can unlock the lock assembly 104 according to the identified identification information. (Refer to...) Figure 5 In (b), the driving component 1041 can move the locking component 1042 away from the second interface 102, and the locking assembly 104 is in the unlocked position. At this time, the first interface 201 can be plugged into the second interface 102; see reference. Figure 5 (c) and Figure 5 In (d) of some embodiments, the locking assembly 104 may be disposed outside the housing assembly of the electric actuator 1. In this case, a through hole may be opened in the side wall of the second interface 102. In the initial state, refer to Figure 5 In (c), the lock assembly 104 is in the locked position, and the locking member 1042 penetrates the through hole in the side wall of the second interface 102, so that at least a portion of the locking member 1042 extends into the second interface 102. For example, the entire locking member 1042 can be inserted into the second interface 102, or only a portion of the locking member 1042 can be inserted into the second interface 102. In this case, if the first interface 201 is plugged into the second interface 102, the locking member 1042 will interfere with the first interface 201, preventing further insertion between the first interface 201 and the second interface 102. When the first identifier 103 of the electric actuator 1 identifies the identification information of the first identifier 202 of the distribution panel 2, the first controller 112 can unlock the lock assembly 104 according to the identified information. (Refer to...) Figure 5In (d) of FIG. 1, the driving member 1041 can drive the locking member 1042 to slide away from the second interface 102, and the locking assembly 104 is in the unlocking position. At this time, the first interface 201 can be inserted into the second interface 102.

[0081] The locking member 1042 is arranged outside the second interface 102 to unlock the second interface 102 by the locking assembly 104, and at least a part of the locking member 1042 is arranged inside the second interface 102 to lock the second interface 102 by the locking assembly 104. The position of the locking member 1042 can be observed to determine whether the locking assembly 104 is in the locked state. For example, when at least a part of the locking member 1042 is observed to be arranged inside the second interface 102, it can be directly and quickly determined that the locking assembly 104 is in the locked state. In this way, the difficulty of the operation can be reduced, and the efficiency of the operation can be improved.

[0082] For example, the driving member 1041 can be an electric push rod, the main body of the electric push rod can be fixed to the electric executor 1, the locking member 1042 can be a locking rod, the locking rod is connected to the rod body of the electric push rod, and the rod body of the electric push rod can drive the locking rod to move when the rod body of the electric push rod extends and retracts.

[0083] Of course, the driving member 1041 of the locking assembly 104 can also be a motor and a transmission member, the transmission member can be connected to the output shaft of the motor and the locking member 1042 respectively, and the transmission member can convert the rotary motion of the output shaft of the motor into the linear motion of the locking member 1042. For example, the transmission member can be a gear and rack assembly. In this way, the motor can drive the locking member 1042 to move when the motor is started, thereby unlocking or locking the locking assembly 104.

[0084] Referring to Figure 5 (e) and Figure 5 (f) of FIG. 1, in some embodiments, the locking member 1042 is rotationally arranged in the housing assembly of the electric executor 1, at least a part of the locking member 1042 is located in the second interface, and the driving member 1041 is used to drive the locking member 1042 to rotate. When the locking member 1042 is in the locked position, the length direction of the locking member 1042 is arranged obliquely to the insertion direction of the second interface 102 and the first interface 201. When the locking member 1042 is in the unlocking position, the length direction of the locking member 1042 is arranged parallel to the insertion direction of the second interface 102 and the first interface 201.

[0085] It should be noted that the insertion direction of the second interface 102 and the first interface 201 can be the axial direction of the second interface 102. The length direction of the locking member 1042 is parallel to the insertion direction of the second interface 102 and the first interface 201, that is, the length direction of the locking member 1042 is parallel to the axial direction of the second interface 102.

[0086] When the length direction of the locking member 1042 is parallel to the plugging direction of the second interface 102 and the first interface 201, the gap between the inner contacts of the first interface 201 can avoid the locking member 1042, thus, the locking member 1042 and the first interface 201 will not interfere with each other, referring to Figure 3 (e) in the figure, when the angle of the locking member 1042 is inclined relative to the plugging direction of the second interface 102 and the first interface 201, the lock assembly 104 is in the locked position, at this time, if the first interface 201 is plugged with the second interface 102, the locking member 1042 will interfere with the first interface 201 to block the further plugging of the first interface 201 and the second interface 102, when the first identifier 103 of the electric actuator 1 identifies the information of the first identification member 202 of the switchboard 2, the first controller 112 can unlock the lock assembly 104 according to the identified information, referring to ​ (f) in the figure, the driving member 1041 can drive the locking member 1042 to rotate to be parallel to the plugging direction of the second interface 102 and the first interface 201, at this time, the first interface 201 is plugged with the second interface 102, the locking member 1042 will not interfere with the contacts of the first interface 201, the lock assembly 104 is in the unlocked position, and the first interface 201 can be smoothly plugged with the second interface 102.

[0087] The locking member 1042 is rotationally connected with the electric actuator 1, the locking member 1042 is driven by the driving member 1041 to rotate, and the lock assembly 104 is switched between the locked position and the unlocked position by adjusting the angle of the locking member 1042, thus, the stroke of the driving member 1041 can be appropriately reduced, and the size of the driving member 1041 is reduced, and the space occupied by the driving member 1041 in the electric actuator 1 is reduced.

[0088] For example, the driving member 1041 can be an electric push rod, and the locking member 1042 can be a locking rod, the locking rod can be rotationally connected with the rod body of the electric push rod, wherein when the rod body of the electric push rod is extended and retracted, the locking rod can be driven to rotate, so as to adjust the angle of the locking rod; in some other embodiments, the rod body of the electric push rod can also be connected with the locking rod through a connecting rod, thus, the installation position of the electric push rod can be conveniently adjusted.

[0089] Of course, the driving member 1041 of the lock assembly 104 can also be a motor, the output shaft of the motor is connected with the locking rod, and the motor can drive the locking rod to rotate when the motor is started, so as to realize the unlocking or locking of the lock assembly 104.

[0090] In some embodiments, after the electric actuator 1 is separated from the switchboard 2, i.e. after the first controller 112 of the electric actuator 1 detects that the second interface 102 is separated from the first interface 201, the first controller 112 can automatically adjust the lock assembly 104 from the unlocked position to the locked position, so as to reduce the probability of incorrect plugging of the electric actuator 1 and the first interface 201, and to improve the safety of the operation.

[0091] Of course, in other possible embodiments, when the locking member 1042 is in the locked position, the locking member 1042 can abut against a part of the switchboard 2 that is not the first interface 201 during the insertion of the second interface 102 into the first interface 201, so as to limit the insertion of the second interface 102 into the first interface 201, and thus lock the second interface 102; when the locking member 1042 is in the unlocked position, the locking member 1042 does not abut against the switchboard 2 during the insertion of the second interface 102 into the first interface 201, so as to allow the insertion of the second interface 102 into the first interface 201, and thus unlock the second interface 102. The present embodiment is not limited in this regard.

[0092] In some embodiments, the electric actuator 1 is further provided with a plurality of buttons 107, which are in communication connection with the first controller 112. For example, the buttons 107 can include confirmation buttons, selection buttons, shutdown buttons, return buttons, etc. The worker can press the buttons 107 to realize information interaction with the electric actuator 1, so as to facilitate the operation; in other embodiments, the display screen 105 of the electric actuator 1 can be a touch display screen 105, so that the worker can directly operate on the display screen 105, and the buttons 107 can not be provided.

[0093] In some embodiments, the electric actuator 1 is further provided with a power switch 108, which can be connected with a power supply inside the electric actuator 1. The power supply can be connected with the first identifier 103 and the first controller 112 inside the electric actuator 1, and the power switch 108 can control the start and stop of the power supply, so as to control the start and stop of the electric actuator 1.

[0094] In some embodiments, the electric actuator 1 is further provided with a charging interface 109 connected with the power supply. When the power supply of the electric actuator 1 has a low power, the power supply can be charged through the charging interface 109.

[0095] In some embodiments, the electric actuator 1 can be connected with the switchboard 2 according to the following steps:

[0096] S10, the first identifier 103 of the electric actuator 1 scans the first identification member 202 corresponding to the first interface 201 of the switchboard 2, and the first identifier 103 sends the identified information to the first controller 112 in the electric actuator 1;

[0097] S20, the first controller 112 controls the lock assembly 104 to be unlocked according to the received information;

[0098] S30, the second interface 102 of the electric actuator 1 is plugged with the first interface 201 of the switchboard 2;

[0099] S40, the second identifier 303 of the terminal device 3 is close to the second identification member 110 of the electric actuator 1, so that the second identifier 303 and the second identification member 110 generate induction, thereby starting the first wireless connection module 111 and the second wireless connection module 305;

[0100] S50, the first wireless connection module 111 and the second wireless connection module 305 form a communication connection;

[0101] S60, the terminal device 3 is electrically operated on the electric actuator 1;

[0102] S70, the communication connection between the first wireless connection module 111 and the second wireless connection module 305 is disconnected.

[0103] In the above embodiment, the terminal device 3 can form one-to-one communication connection with the electric actuator 1, that is, at the same time, the terminal device 3 is connected with only one electric actuator 1, in other embodiments, the terminal device 3 can simultaneously form communication connection with multiple electric actuators 1 plugged in the switchboard 2, at this time, the steps between S50 and S60 can be added as follows:

[0104] S51, the connection between the first wireless connection module 111 and the second wireless connection module 305 in S50 is maintained, the terminal device 3 is moved, the second identifier 303 of the terminal device 3 is close to the second identification member 110 of another electric actuator 1, so that the second identifier 303 and the second identification member 110 of the another electric actuator 1 generate induction, thereby starting the first wireless connection module 111 of the another electric actuator 1;

[0105] S52, the first wireless connection module 111 and the second wireless connection module 305 of the another electric actuator 1 form a communication connection;

[0106] S53, S51 and S52 are repeated until the terminal device 3 forms communication connection with all preset electric actuators 1.

[0107] Reference ​The embodiment of the application further provides a distribution panel 2 which is used in cooperation with the electric actuator 1 in any of the above embodiments, and the distribution panel 2 is provided with a first interface 201 and a first identification member 202 corresponding to the first interface 201, the first interface 201 is used for adaptive plug-in connection with the second interface 102 of the electric actuator 1, and the first identification member 202 is used for the first identifier 103 of the electric actuator 1 to identify the identification information of the corresponding first interface 201.
