[0031] Please refer to Figure 1-Figure 6 , an embodiment of the present application discloses a smart charging cabinet 100.

[0032] In one embodiment, if Figure 1-Figure 3As shown, the smart charging cabinet 100 includes a cabinet 10, at least one smart socket 20 and a main control unit. The cabinet 10 serves as the bearing structure of the entire smart charging cabinet 100. An opening 101 is provided along the height direction of the cabinet 10, and the staff can place the charging device in the cabinet 10 through the opening 101. The cabinet door 11 is movably connected to the cabinet 10, so that the staff can open the cabinet door 11 and cover the opening 101. The movable connection can be a hinge connection or an axle pin connection. The cabinet door 11 is provided with an observation window 91, and the material of the observation window 91 is transparent flame-retardant organic glass, so that the staff can understand the situation in the cabinet 10 at any time.

[0033] At least one smart socket 20, the smart socket 20 is used to supply power to the charging device, the smart socket 20 includes a housing 21, at least one socket seat 22, at least one current detection device 23 and at least one first switch 24, the housing 21 includes a housing 21 body and a cover plate, the housing 21 body is fixed on the side wall of the cabinet 10 opposite to the opening 101, so that the staff can plug and unplug the plug of the charging device into the socket seat 22, each socket seat 22 has a socket part, at least one socket seat 22 is embedded and fixed in the housing 21, the cover plate is corresponding to each socket seat 22 to open a through hole, when the cover plate is covered on the housing 21 body, each socket part passes through each through hole, so that the socket part is located outside the housing 21, so that the staff can plug and unplug the charging device. The specific charging device can be a battery, and the battery has the characteristic that the corresponding charging current gradually weakens to a critical value as the battery is gradually filled, and the battery is electrically connected to the socket seat 22 through a charger, and the socket seat 22 is universal and adapts to various chargers, thereby improving the charging versatility of the smart charging cabinet 100.

[0034] Each socket 22 is electrically connected to a current detection device 23 and a first switch 24, and then the first switches 24 are connected in series through cables, and then the socket holes are connected in series, which saves the amount of wiring and makes the structure more compact. The current detection device 23 and the first switch 24 are both fixed in the shell 21. The current detection device 23 is used to detect the current of the socket 22 in real time, and send the detected current information to the main control unit in real time; the first switch 24 is used to control the current connection and disconnection of the socket 22, so that the smart charging cabinet 100 can accurately control the current connection and disconnection of each socket 22. Specifically, the current detection device 23 can be a current detector; the first switch 24 can be a relay.

[0035] The main control unit (not marked in the figure) is arranged on the cabinet door 11. The main control unit is electrically connected to the current detection device 23 and the first switch 24 respectively. The main control unit is used to analyze the received current information and control the first switch 24 to cut off or connect the power supply of the socket hole according to the analysis result. Therefore, when the charging device is inserted into the socket 22, the main control unit controls each first switch 24 to turn on the power. After 10 seconds, the current detection device 23 will transmit the current information detected by each socket 22 to the main control unit. The main control unit analyzes the received current information and controls the first switch 24 accordingly according to the analysis result. When the analysis result shows that there is no current, the first switch 24 is controlled to disconnect the power supply and cut off the power supply of the socket 22 that is not connected to the charging device. When the analysis result shows that there is current, the first switch 24 is controlled to keep the power supply, so that the smart socket 20 automatically supplies power to the charging device. When the charging device is fully charged, the corresponding charging current gradually decreases to a preset critical value as the charging device is gradually filled with electricity. When the current is less than the preset critical value, the main control unit sends a disconnect signal to the first switch 24. After receiving the disconnect signal, the first switch 24 automatically disconnects the power supply of the corresponding socket hole, so that the smart charging cabinet 100 can stop automatically when fully charged and cut off the power in time to avoid the risk of overcharging. There is no need to manually check whether it is full and unplug the plug, which reduces the labor intensity of the staff, improves the intelligence level of the smart charging cabinet 100, and improves the overall equipment efficiency of the smart charging cabinet 100.

[0036] Furthermore, the main control unit includes a programmable logic controller (not shown) and a touch screen computer 30. Specifically, the programmable logic controller uses a type of programmable memory for storing programs internally, executes user-oriented instructions such as logical operations, sequential control, timing, counting and arithmetic operations, and controls various types of machinery or production processes through digital or analog input / output. The touch screen computer 30 is set on the cabinet door 11, which is convenient for the staff to view and operate on the touch screen computer 30. The programmable logic controller is integrated on the touch screen computer 30 and is electrically connected to the touch screen computer 30, the current detection device 23 and the first switch 24 respectively. The programmable logic controller stores the received current detection information, so that the staff can view the relevant current information through the touch screen computer 30 and monitor the charging status of the charging device in real time.

[0037] Among them, the touch screen computer 30 also presets the level of facial recognition authentication, and the staff can open the cabinet door 11 through facial recognition, further improving the intelligence of the smart charging cabinet 100.

[0038] In one embodiment, if Figure 2 and Figure 3As shown, the smart sockets 20 are provided with a plurality of layers 40 corresponding to the number of the smart sockets 20 in the smart charging cabinet 100. The layers 40 are used to carry charging devices. The plurality of smart sockets 20 are arranged on an inner wall of the cabinet 10 opposite to the opening 101 at intervals. The plurality of layers 40 are arranged in the cabinet 10 at intervals. Each layer 40 separates two adjacently arranged smart sockets 20, so that each layer 40 is provided with a corresponding smart socket 20, so that the charging device can be charged when placed on the layer 40. The cabinet 10 is divided into a plurality of charging areas by the arrangement of a plurality of layers 40. On the one hand, the number of charging devices of the smart charging cabinet 100 is increased, and on the other hand, the management capability of the smart charging cabinet 100 for charging devices is improved. At the same time, each layer 40 only needs to be provided with a smart socket 20 to realize charging of a plurality of charging devices, and it is not necessary to provide a plurality of sockets on each layer 40 at the same time, so that the structure of the smart charging cabinet 100 is more compact and simple.

[0039] Furthermore, the smart socket 20 also includes a second switch (not shown), which can be a contactor. The working principle of the contactor is to control the on-off of the main contact connected to the main circuit by controlling the on-off of the auxiliary contact connected to the control circuit to meet the requirements of the control circuit. The smart charging cabinet 100 includes an electric control module (not shown) and an electric energy distribution unit (not shown). The electric control module and the electric energy distribution unit are both arranged at the bottom of the cabinet 10. The electric control module is used to control the on and off of the total power supply of the smart charging cabinet 100. The electric control module can be a circuit breaker. The circuit breaker refers to a switch device that can close, carry and disconnect the current under normal circuit conditions and can close, carry and disconnect the current under abnormal circuit conditions within a specified time. The power distribution unit includes relays and contactors, which are used to supply power to multiple smart sockets 20 respectively. The electronic control module is electrically connected to the mains power grid and the power distribution unit respectively. The mains power grid is 220V. After being connected to the smart charging cabinet 100, it is protected by a circuit breaker and then connected to the power distribution unit. Power is supplied to each second switch through relays and contactors in turn to complete the primary power distribution, and the second switches are electrically connected to each socket 22 to complete the secondary power distribution. The circuit control of the smart charging cabinet 100 is realized through the two power distributions. When a charging device is inserted, the second switch turns on the power of all the sockets 22 of the layer board 40, the current detection device 23 detects the current of each socket 22, and sends all current information to the programmable logic controller. After receiving the current information, the programmable logic controller stores and feeds back the current information to the touch screen computer 30. The touch screen computer 30 processes and analyzes the received current information according to a preset program, and feeds back the analysis result to the programmable logic controller. The programmable logic controller then sends a corresponding signal to the corresponding first switch 24. The charging device continues to be powered, and the first switch 24 corresponding to the charging device not plugged in disconnects the power supply, thereby realizing precise control of the charging device's full stop, improving the intelligence level of the smart charging cabinet 100, and improving the overall equipment efficiency of the smart charging cabinet 100.

[0040] In one embodiment, if Figure 5-Figure 7In order to improve the internal heat dissipation effect of the smart charging cabinet 100, a plurality of heat dissipation structures 60 are arranged in the smart charging cabinet 100, and according to the principle that hot air rises, the plurality of heat dissipation structures 60 are arranged on the inner wall of the cabinet 10 near the inner top thereof, that is, the heat dissipation structure 60 is arranged on the inner wall of the cabinet 10, and the heat dissipation structure 60 is arranged adjacent to the inner top of the cabinet 10, so that the heat dissipation structure 60 discharges the hot air out of the cabinet 10, and a plurality of air outlets 103 are arranged at the position of the inner wall of the cabinet 10 corresponding to each heat dissipation structure 60, so that the heat dissipation structure 60 discharges the heat in the cabinet 10 out of the cabinet 10 through the air outlets 103, and the bottom of the cabinet 10 is provided with a plurality of air outlets 103. There are multiple air inlet holes 102. When the cabinet door 11 covers the opening 101, the multiple layer plates 40 form a first gap 401 with the cabinet door 11 on the side facing the opening 101, so that the air inlet holes 102, the first gap 401 and the air outlet holes 103 form a first air circulation channel, so that cold air enters the cabinet 10 through the air inlet holes 102, which reduces the temperature in the cabinet 10 to a certain extent, and the cold air flows to the air outlet holes 103 through the first gap 401, and the heat dissipation structure 60 speeds up the flow rate of cold air and hot air, accelerates the air circulation in the cabinet 10, and then accelerates the discharge of hot air in the cabinet 10 out of the cabinet 10, thereby improving the heat dissipation efficiency of the smart charging cabinet 100.

[0041] The specific heat dissipation structure 60 may be a fan.

[0042] Further, such as Figure 6 and Figure 7 As shown, the cabinet 10 includes a first side panel 104 and a second side panel 105, and the first side panel 104 and the second side panel 105 are respectively located on opposite sides of the opening 101, and a first recessed portion 41 is provided along the longitudinal direction (height direction) of the first side panel 104. The first recessed portion 41 forms a second gap 402 with the first side panel 104 of the plurality of layer panels 40, and the air inlet 102, the second gap 402 and the air outlet 103 are interconnected, so that the air inlet 102, the second gap 402 and the air outlet 103 form a second air circulation channel, which further improves the air circulation speed in the cabinet 10, and further improves the heat dissipation efficiency of the smart charging cabinet 100.

[0043] A second recessed portion 42 is provided along the longitudinal direction (height direction) of the second side plate 105, and the second recessed portions 42 form a third gap 403 with the second side plate 105 of the multiple layer plates 40, and the air inlet hole 102, the third gap 403 and the air outlet hole 103 are interconnected, so that the air inlet hole 102, the third gap 403 and the air outlet hole 103 form a third air circulation channel, further improving the air circulation speed in the cabinet body 10, and further improving the heat dissipation efficiency of the smart charging cabinet 100.

[0044] In one embodiment, if Figure 6 and Figure 7 As shown, the intelligent charging cabinet 100 also includes a plurality of sensing components (not marked in the figure), and the plurality of sensing components are all arranged in the cabinet body 10, and each sensing component is correspondingly located above each layer board 40. When the charging device is placed on the layer board 40, the sensing component senses the charging device and transmits the signal to the programmable logic controller. After receiving the signal, the programmable logic controller controls the second switch to turn on the power of all the sockets 22 on the layer board 40. After 10 seconds, the current detection device 23 summarizes the current information of all the sockets 22 on the layer and feeds it back to the programmable logic controller. The programmable logic controller stores the received current information and feeds it back to the touch screen computer 30. The touch screen computer 30 performs data analysis according to a preset program and feeds back the analysis results to the programmable logic controller. The programmable logic controller controls the connection and disconnection of each first control switch accordingly. The device with a charging device continues to be powered on, and the device without a charging device controls the first switch 24 to be disconnected, so as to realize automatic control of the charging process, monitor the charging status of the charging device in real time, and stop automatically when fully charged.

[0045] Further, such as Figure 6 and Figure 7 As shown, the induction component includes a receiving end 51 and a transmitting end 50. The cabinet 10 has two oppositely arranged side walls respectively connected to the opening 101. The receiving end 51 and the transmitting end 50 are respectively fixed on the two side walls. The transmitting end 50 emits red light or infrared, and the receiving end 51 receives the red light or infrared. When the charging device is placed on the layer plate 40, the charging device will cut off the red light or infrared, and the induction component will output a signal to the programmable logic controller. After receiving the signal, the programmable logic controller stores it and feeds it back to the touch screen computer 30. The touch screen computer 30 processes the data according to the signal and feeds the result back to the programmable logic controller. The programmable logic controller controls the second switch to be powered on. Automatic charging of the charging device is realized, human interference is reduced, and the labor intensity of the staff is reduced, thereby improving the intelligence of the smart charging cabinet 100 and improving the overall equipment efficiency of the smart charging cabinet 100.

[0046] Specifically, the sensing component can be a through-beam photoelectric sensor, in which the transmitting end 50 emits red light or infrared light, and the receiving end 51 receives it. When an object passes through and cuts off the light, a signal is output. The four pins refer to the wires, and the transmitting end 50 only needs to be connected to the brown wire and the blue wire, the brown wire is connected to the positive pole, and the blue wire is connected to the negative pole. In addition to the brown and blue wires, the receiving end 51 also needs to be connected to the black wire as the signal output wire.

[0047] In one embodiment, if Figure 1 and Figure 7As shown, the smart charging cabinet 100 also includes a smoke sensor 70 and a fire extinguishing device 80. Both the smoke sensor 70 and the fire extinguishing device 80 are arranged on the inner top of the cabinet 10. Both the smoke sensor 70 and the fire extinguishing device 80 are electrically connected to the programmable logic controller of the main control unit. When the smart charging cabinet 100 catches fire and produces smoke, when the smoke concentration reaches a certain level, the smoke sensor 70 senses it and transmits a signal to the programmable logic controller. The programmable logic controller controls the fire extinguishing device 80 to open and extinguish the fire to prevent the fire from spreading. Specifically, the smoke sensor 70 is a smoke probe; the fire extinguishing device 80 is a dry ice fire extinguisher, in which the carbon dioxide fire extinguishing agent is sprayed from the siphon tube through the bottle valve to the spray gun, so that the oxygen concentration in the combustion area drops rapidly. When the carbon dioxide reaches a sufficient concentration, the flame will suffocate and extinguish. At the same time, because the liquid carbon dioxide will quickly gasify and absorb a large amount of heat in a very short time, it has a certain cooling effect on the burning material and also helps to extinguish the fire. The carbon dioxide fire extinguishing agent can be quickly diffused to the entire interior of the cabinet 10 through the first air circulation channel, the second air circulation channel and the third air circulation channel to extinguish the fire and reduce the safety hazards caused by charging.

[0048] Furthermore, the smart charging cabinet 100 also includes an alarm 90, which is arranged on the outer top of the cabinet body 10 and is electrically connected to the programmable logic controller of the main control unit. When the programmable logic controller controls the fire extinguishing device 80 to turn on, it simultaneously transmits a signal to the alarm 90 to control the alarm 90 to turn on, reminding the staff that there is a fire or other abnormal conditions in the smart charging cabinet 100, thereby reducing the safety hazards caused by charging.

[0049] In summary, the full-fill automatic stop process of this application is:

[0050] The staff performs facial recognition, opens the door of the smart charging cabinet 100, places the charging device on the shelf 40, and then inserts the plug electrically connected to the charging device into the socket 22. The charging device cuts off the red light. At this time, the photoelectric sensor arranged in the cabinet 10 senses the charging device and transmits the sensing signal to the programmable logic controller. The programmable logic controller controls the corresponding contactor (the second switch) to supply power to all the sockets 22 of the corresponding smart socket 20. After 10 seconds, the current detection device 23 will detect the current information of each socket 22 and feed it back to the programmable logic controller in real time. The programmable logic controller stores the received current signal and sends it to the touch screen computer 30. The touch screen computer 30 performs data analysis according to the preset program, and determines which socket 22 does not need power supply, and feeds back the signal to the programmable logic controller. The programmable logic controller controls the corresponding relay (the first switch 24) to disconnect the power supply of the socket 22, and the socket with the charger is powered normally. When the battery is fully charged, the current gradually decreases to the preset critical value. The programmable logic controller controls the corresponding relay to disconnect the power supply to achieve full automatic stop.
