[0023] In one embodiment, as shown in FIG1, a door lock device is provided, applied to an energy storage and power distribution device. The energy storage and power distribution device includes a door body and a power distribution circuit 50. The door lock device includes a door lock module 10, a detection circuit 20, and a switching circuit 30. The door lock module 10 is disposed on the door body. The detection circuit 20 is configured to be connected to the power distribution circuit 50. The switching circuit 30 is connected between the detection circuit 20 and the door lock module 10. The detection circuit 20 is configured to detect the energized state of the power distribution circuit 50 and, based on the detection result, control the on / off state of the switching circuit 30 to lock or unlock the door body using the door lock module 10.

[0024] The door lock device can be applied to energy storage distribution equipment, which refers to power distribution equipment used in energy storage battery systems. This equipment can be, but is not limited to, combiner cabinets, control cabinets, or PCS cabinets. For example, taking the application of a door lock device in a combiner cabinet as an example, the combiner cabinet includes a cabinet body and a door. Multiple electrical devices are installed inside the cabinet, forming a power distribution circuit 50. In one example, the electrical devices can be DC devices, and the power distribution circuit 50 is a circuit formed by connecting these DC devices. DC devices can include busbars (such as copper busbars) and cables, with the busbars connecting to the cables.

[0025] The door lock module 10 is installed on the door body. The door lock module 10 is used to lock or unlock the door body. When the door lock module 10 locks the door body, the operator cannot directly open the door body; when the door lock module 10 unlocks the door body, the operator can directly open the door body. For example, when the door lock module 10 is in a power-off state, it locks the door body, that is, it locks the door body to the cabinet, preventing the operator from directly opening the door body; when the door lock module 10 is in a power-on state, it unlocks the door body, that is, it disengages the door body from the cabinet, allowing the operator to directly open the door body.

[0026] The detection circuit 20 can be used to detect whether there is an electrical signal in the power distribution circuit 50. For example, the detection circuit 20 can be used to detect the voltage signal of the power distribution circuit 50. When the detection circuit 20 detects the voltage signal of the power distribution circuit 50, it determines that the power distribution circuit 50 is energized, and then controls the switch circuit 30 to open, so that the door lock module 10 is in a de-energized state. When the detection circuit 20 does not detect the voltage signal of the power distribution circuit 50, it determines that the power distribution circuit 50 is de-energized, and then controls the switch circuit 30 to open, so that the door lock module 10 is in a energized state.

[0027] The switching circuit 30 can be a relay switch circuit. The switching circuit 30 is connected between the detection circuit 20 and the door lock module 10, forming a door lock control loop between the switching circuit 30, the detection circuit 20, and the door lock module 10. When the switching circuit 30 is open, the door lock control loop is open, and the door lock module 10 is in a de-energized state. At this time, the door lock module 10 locks the door, and the operator cannot directly open the door. When the switching circuit 30 is closed, the door lock control loop is closed, and the door lock module 10 is in a energized state. At this time, the door lock module 10 unlocks the door, and the operator can directly open the door.

[0028] For example, based on the detection circuit 20 connected to the power distribution module, and the switch circuit 30 connected between the detection circuit 20 and the door lock module 10, the detection circuit 20 detects the energized state of the power distribution circuit 50 inside the cabinet in real time. If the detection circuit 20 detects voltage in the power distribution circuit 50 (i.e., voltage greater than a preset threshold), it determines that the power distribution circuit 50 is energized. The detection circuit 20 then controls the switch circuit 30 to disconnect, causing the door lock module 10 to be de-energized. At this time, the door lock module 10 locks the door, preventing operators from directly opening it, effectively preventing operators from accidentally entering an energized area, reducing the risk of electric shock, and improving safety. If the detection circuit 20 detects no voltage in the power distribution circuit 50 (i.e., voltage less than a preset threshold), it determines that the power distribution circuit 50 is de-energized. The detection circuit 20 then controls the switch circuit 30 to conduct, energizing the door lock module 10. At this time, the door lock module 10 unlocks the door, allowing operators to directly open it.

[0029] In this embodiment, the door lock module 10 is mounted on the door. The detection circuit 20 is connected to the power distribution circuit 50, and the switch circuit 30 is connected between the detection circuit 20 and the door lock module 10. The detection circuit 20 is configured to detect the energized state of the power distribution circuit 50 and, based on the detection result, control the switching circuit 30 to lock or unlock the door. This achieves door lock status control based on the energized state of the power distribution circuit 50. In this embodiment, by detecting the energized state of the power distribution circuit 50 through the detection circuit 20, and switching the switching circuit 30 based on whether the power distribution circuit 50 is energized, the door lock module 10 controls the door to lock or unlock based on the switching circuit 30. This ensures that when the power distribution circuit 50 is energized, the door is locked and cannot be opened; when the power distribution circuit 50 is de-energized, the door is unlocked and can be opened. This effectively prevents personnel from accidentally entering energized areas, reduces the risk of electric shock to the power distribution circuit 50, and improves safety.

[0030] In one embodiment, as shown in FIG2, the door lock module 10 includes a transmission member 110 and a bolt 120; the transmission member 110 is connected to a switch circuit 30, and the transmission member 110 is configured to attract the bolt 120 to unlock the door when the switch circuit 30 is turned on; the transmission member 110 is also configured to disengage from the bolt 120 to lock the door when the switch circuit 30 is turned off.

[0031] The bolt 120 has a first end movably mounted on the door and a second end movably connected to the cabinet. For example, if the cabinet has a recess, when the second end of the bolt 120 is inserted into the recess, the door is locked to the cabinet, preventing the operator from opening it directly. When the second end of the bolt 120 disengages from the recess, the door is released from the cabinet, allowing the operator to open it directly. When the bolt 120 is in its reset or initial state, the second end is inserted into the recess of the cabinet.

[0032] The transmission component 110 can be used to move the bolt 120. For example, based on the connection of the transmission component 110 to the switch circuit 30, when the detection circuit 20 detects voltage in the power distribution circuit 50 (i.e., voltage greater than a preset threshold), it determines that the power distribution circuit 50 is energized. The detection circuit 20 then controls the switch circuit 30 to disconnect, causing the transmission component 110 to disengage from the bolt 120. The bolt 120 then resets and inserts into the groove of the cabinet, locking the door. Operators cannot directly open the door, effectively preventing accidental entry into an energized area, reducing the risk of electric shock, and improving safety. If the detection circuit 20 detects no voltage in the power distribution circuit 50 (i.e., voltage less than a preset threshold), it determines that the power distribution circuit 50 is de-energized. The detection circuit 20 then controls the switch circuit 30 to conduct, causing the transmission component 110 to attract the bolt 120, disengaging the bolt 120 from the groove of the cabinet, unlocking the door and allowing operators to open it directly.

[0033] In one example, as shown in Figure 3, the transmission component 110 is an electromagnet 112. The electromagnet 112 can be positioned near the first end of the bolt 120. Based on the connection of the electromagnet 112 to the switch circuit 30, when the detection circuit 20 detects voltage in the power distribution circuit 50, it determines that the power distribution circuit 50 is energized. The detection circuit 20 then controls the switch circuit 30 to disconnect, de-energizing the electromagnet 112. This prevents the electromagnet 112 from attracting the bolt 120, causing the bolt 120 to reset and insert into the recess in the cabinet, thus locking the door. This prevents operators from directly opening the door, effectively preventing accidental entry into an energized area, reducing the risk of electric shock, and improving safety. If the detection circuit 20 detects no voltage in the power distribution circuit 50, it determines that the power distribution circuit 50 is de-energized. The detection circuit 20 then controls the switch circuit 30 to conduct, energizing the electromagnet 112. The electromagnet 112 attracts the bolt 120, causing the bolt 120 to disengage from the recess in the cabinet, unlocking the door and allowing operators to open it directly.

[0034] In one embodiment, as shown in FIG3, the door lock module 10 further includes a door lock connector 130; the door lock connector 130 is disposed on the cabinet; the door lock connector 130 is movably connected to the bolt 120 so that the door is unlocked when the door lock connector 130 is disengaged from the bolt 120, and the door lock is locked when the door lock connector 130 is connected to the bolt 120.

[0035] The door lock connector 130 can be installed on the cabinet by screwing or welding. In another example, the door lock connector 130 and the cabinet can also be an integrally formed structure. The door lock connector 130 may have a groove. The first end of the bolt 120 is movably connected to the transmission component 110, and the second end of the door lock connector 130 is movably connected to the bolt 120. When the detection circuit 20 detects that the power distribution circuit 50 is energized, the detection circuit 20 controls the switch circuit 30 to disconnect, causing the transmission component 110 to disengage from the bolt 120. Then, the second end of the bolt 120 inserts into the groove of the door lock connector 130, thus locking the door to the cabinet and preventing the operator from directly opening the door. When the detection circuit 20 detects that the power distribution circuit 50 is de-energized, the detection circuit 20 controls the switch circuit 30 to conduct, causing the transmission component 110 to attract the bolt 120. Then, when the second end of the bolt 120 disengages from the groove of the door lock connector 130, the door separates from the cabinet, allowing the operator to directly open the door.

[0036] In one embodiment, as shown in FIG4, the switching circuit 30 includes a first contact switch 310, the first end of the first contact switch 310 is connected to the detection circuit 20, and the second end of the first contact switch 310 is connected to the transmission component 110.

[0037] The first contact switch 310 can be a relay switch, and it has a switch contact, which can be a normally closed contact. For example, when the detection circuit 20 detects that the power distribution circuit 50 is energized, it controls the normally closed contact of the first contact switch 310 to open, de-energizing the transmission component 110. This causes the transmission component 110 to disengage from the locking bolt 120, allowing the bolt 120 to insert into the groove on the cabinet, thus locking the door. This prevents operators from directly opening the door, effectively preventing accidental entry into an energized area, reducing the risk of electric shock, and improving safety. When the detection circuit 20 detects that the power distribution circuit 50 is de-energized, it controls the normally closed contact of the first contact switch 310 to remain closed, energizing the transmission component 110. This causes the transmission component 110 to attract the locking bolt 120, disengaging it from the groove on the cabinet, thus unlocking the door and allowing operators to open it directly.

[0038] In one example, as shown in Figure 7, the first contact switch 310 may include a relay coil and a first normally closed contact, and the transmission component 110 is an electromagnet 112. When the power distribution circuit 50 is energized, the detection circuit 20 is in a conductive state to the door lock control circuit, causing the relay coil to be energized. Consequently, the first normally closed contact opens, the electromagnet 112 is not energized, and the electromagnet 112 cannot engage the bolt 120, causing the bolt 120 to insert into the groove on the cabinet, thereby locking the door and preventing the operator from directly opening it. When the power distribution circuit 50 is de-energized, the detection circuit 20 is in a disconnected state to the door lock control circuit, causing the relay coil to be de-energized. Consequently, the first normally closed contact closes, the electromagnet 112 is energized, and the electromagnet 112 engages the bolt 120, causing the bolt 120 to disengage from the groove on the cabinet, thereby unlocking the door. The operator can then directly open the door, thus improving safety, preventing the operator from accidentally entering an energized area, and reducing the risk of electric shock.

[0039] In one embodiment, as shown in FIG4, the door lock device further includes a light-emitting module 40, and the switch circuit 30 further includes a second contact switch 320; the first end of the second contact switch 320 is connected to the detection circuit 20, and the second end of the second contact switch 320 is connected to the light-emitting module 40.

[0040] The light-emitting module 40 can be an LED light-emitting module. When the power distribution circuit 50 is energized, the light-emitting module 40 is triggered to work, causing the light-emitting module 40 to light up, so as to remind the operator that the power distribution circuit 50 of the cabinet is in a energized state. The second contact switch 320 can be a relay switch. The second contact switch 320 is provided with switch contacts, and the switch contacts of the second contact switch 320 can be normally open contacts.

[0041] Since the second contact switch 320 is connected between the detection circuit 20 and the light-emitting module 40, when the detection circuit 20 detects that the power distribution circuit 50 is energized, the detection circuit 20 controls the normally open contact of the second contact switch 320 to close, making the circuit between the detection circuit 20 and the light-emitting module 40 conductive, thereby triggering the light-emitting module 40 to light up, reminding the operator that the power distribution circuit 50 is energized. When the detection circuit 20 detects that the power distribution circuit 50 is de-energized, the detection circuit 20 controls the normally open contact of the second contact switch 320 to open, making the circuit between the detection circuit 20 and the light-emitting module 40 disconnect, thereby turning off the light-emitting module 40, thus saving energy and making it convenient for the operator to directly open the door.

[0042] For example, as shown in Figure 7, the light-emitting module 40 may include a light-emitting diode and a second resistor. The second contact switch 320 may include a relay coil and a first normally open contact. The first end of the second resistor is connected to the second end of the first normally open contact, and the second end of the second resistor is connected to the anode of the light-emitting diode. The cathode of the light-emitting diode is connected to the negative terminal of the first power supply 210. The relay coil is connected to the detection circuit 20 and the positive terminal of the first power supply 210 respectively. When the power distribution circuit 50 is energized, the detection circuit 20 is in a conducting state to the door lock control circuit, which energizes the relay coil and closes the first normally open contact. At this time, the electrical signal output by the first power supply 210 is supplied to the light-emitting diode after passing through the second resistor, thereby lighting up the light-emitting diode and reminding the operator that the power distribution circuit 50 is energized.

[0043] In one embodiment, as shown in FIG5, the detection circuit 20 includes a first power supply 210, a processing module 220, and a third contact switch 240. The processing module 220 is connected to the power distribution circuit 50 and the third contact switch 240. The third contact switch 240 is connected between the first power supply 210 and the switching circuit 30.

[0044] The first power supply 210 may be, but is not limited to, a 24V DC power supply. The processing module 220 may be, but is not limited to, a BMS (Battery Management System) or an EMS (Energy Management System). The third contact switch 240 may be a relay switch, and the third contact switch 240 is provided with switch contacts, which may be normally open contacts.

[0045] The processing module 220 is connected to the power distribution circuit 50 and the third contact switch 240. The third contact switch 240 is connected between the first power supply 210 and the switching circuit 30. The processing module 220 can detect the energized state of the power distribution circuit 50. When the processing module 220 detects that the power distribution circuit 50 is energized, it controls the third contact switch 240 to close, thereby allowing the first power supply 210 to supply power to the switching circuit 30. This causes the switching circuit 30 to switch from normally closed to open, de-energizing the door lock module 10. At this time, the door lock module 10 locks the door, preventing operators from directly opening it. This effectively prevents operators from accidentally entering an energized area, reduces the risk of electric shock, and improves safety. If the processing module 220 detects that the power distribution circuit 50 is de-energized, the processing module 220 controls the third contact switch 240 to open, thereby disconnecting the first power supply 210 from the switch circuit 30, causing the switch circuit 30 to return to its normally closed state. Then, the first power supply 210 supplies power to the door lock module 10, enabling the door lock module 10 to unlock the door, allowing the operator to directly open the door.

[0046] In one embodiment, as shown in FIG6, the processing module 220 includes a detection interface 222 and a processing chip 224. The detection interface 222 is connected between the power distribution circuit 50 and the processing chip 224, and the processing chip 224 is connected to the third contact switch 240.

[0047] Among them, the detection interface 222 can be a voltage detection interface, and the processing chip 224 can be a BMS or EMS processing chip 224.

[0048] For example, a detection interface 222 is connected between the power distribution circuit 50 and the processing chip 224. The processing chip 224 is connected to a third contact switch 240, which may include a relay coil and a second normally open contact. The detection interface 222 detects the voltage signal of the power distribution circuit 50. Based on the received voltage signal, the processing chip 224 determines that the power distribution circuit 50 is energized when the voltage signal is greater than 0. Then, the processing chip 224 controls the relay coil of the third contact switch 240 to be energized, causing the second normally open contact of the third contact switch 240 to close. The relay coil of the first contact switch 310 is energized, and the first normally closed contact of the first contact switch 310 is opened. The electromagnet 112 is not energized and cannot attract the bolt 120. The bolt 120 is then inserted into the groove of the cabinet, locking the door. Operators cannot directly open the door, effectively preventing operators from accidentally entering the energized area, reducing the risk of electric shock, and improving safety.

[0049] Based on the received voltage signal, the processing chip 224 determines that the power distribution circuit 50 is de-energized when the voltage signal is equal to 0. Then, the processing chip 224 controls the relay coil of the third contact switch 240 to be de-energized, so that the second normally open contact of the third contact switch 240 becomes normally open, the relay coil of the first contact switch 310 is de-energized, the first normally closed contact of the first contact switch 310 becomes normally closed, the electromagnet 112 is energized, the electromagnet 112 attracts the bolt 120, so that the bolt 120 is disengaged from the groove of the cabinet, thereby unlocking the door and allowing the operator to open the door directly.

[0050] In one embodiment, as shown in FIG7, the processing module 220 further includes a first resistor 226, a first transistor 228, and a second power supply 232. The first end of the first resistor 226 is connected to the processing chip 224, the second end of the first resistor 226 is connected to the base of the first transistor 228, the emitter of the first transistor 228 is connected to ground, and the third contact switch 240 is connected between the collector of the first transistor 228 and the second power supply 232.

[0051] Among them, the first resistor 226 can be a freewheeling resistor, the first transistor 228 can be an NPN transistor, and the second power supply 232 can be a 5V DC power supply.

[0052] For example, based on the received voltage signal, the processing chip 224 determines that the power distribution circuit 50 is energized when the voltage signal is greater than 0. It then transmits a high-level signal to the first transistor 228 through the first resistor 226, causing the first transistor 228 to conduct. At this time, the second power supply 232 supplies power to the relay coil of the third contact switch 240, thereby energizing the relay coil of the third contact switch 240 and closing the second normally open contact of the third contact switch 240. Conversely, if the received voltage signal is equal to 0, the processing chip 224 determines that the power distribution circuit 50 is de-energized. It then controls the base of the first transistor 228 to a low-level state, causing the first transistor 228 to disconnect and de-energizing the relay coil of the third contact switch 240, thus turning the second normally open contact of the third contact switch 240 back to normally open.

[0053] In one embodiment, the door lock module is provided with a key slot for inserting a key.

[0054] For example, the door lock module includes a door lock body, inside which a lock cylinder is provided. The door lock body also has a key slot that connects to the lock cylinder. When the corresponding key is inserted into the key slot, the key can cooperate with the lock cylinder. Thus, when the power distribution circuit is energized, since the door cannot be opened directly, if it is necessary to open the door urgently, the key can be inserted and turned in the unlocking direction. When the key is turned to the limit position and force is applied, the bolt will automatically return to the locked position, thereby forcibly opening the door and improving the reliability of the device.

[0055] In one embodiment, an energy storage and distribution device is also provided, including a main body of the distribution device and a door lock device provided in the embodiments of this application. The door lock device is disposed on the main body of the distribution device.

[0056] Among them, energy storage power distribution equipment can be power distribution equipment applied to energy storage battery systems, such as combiner cabinets, control cabinets, or PCS cabinets. The main body of the power distribution equipment may include power distribution circuits, cabinets, and doors. The power distribution circuits are located inside the cabinets, and the door lock device may be located on the door of the main body of the power distribution equipment.

[0057] For a detailed description of the door lock device, please refer to the specific description of the door lock device in the embodiments of this application, which will not be repeated here.

[0058] In this embodiment, the door lock device includes a door lock module, a detection circuit, and a switching circuit. The door lock module is installed on the door body of the main body of the power distribution equipment. The detection circuit is connected to the power distribution circuit. The switching circuit is connected between the detection circuit and the door lock module. The detection circuit is configured to detect the energized state of the power distribution circuit and, based on the detection result, control the switching circuit to lock or unlock the door, thereby controlling the door lock state based on the energized state of the power distribution circuit. This embodiment detects the energized state of the power distribution circuit through the detection circuit, switches the switching circuit on and off based on whether the power distribution circuit is energized, and the door lock module locks or unlocks the door based on the switching circuit. This ensures that when the power distribution circuit is energized, the door is locked and cannot be opened; when the power distribution circuit is de-energized, the door is unlocked and can be opened. This effectively prevents personnel from accidentally entering energized areas, reduces the risk of electric shock to the power distribution circuit, and improves safety.

[0059] Energy storage and distribution equipment may also include components such as DC devices such as busbars. A specific battery system may include more components than those described in the embodiments of this application, or combine certain components, or have different component arrangements.
