The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0035] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0036] Reference Figure 1According to an embodiment of the present invention, an electronic locking mechanism includes an electronic drive device 100, an emergency unlocking mechanism 200, and an emergency key 300. The electronic drive device 100 can actuate its locking assembly 110 to restrict or release the movement of the locking device's locking rod 510, enabling the locking device to lock and unlock. The emergency unlocking mechanism 200 is connected to the locking assembly 110 and can actuate the locking assembly 110 of the electronic drive device 100. The emergency key 300 can be inserted into the emergency unlocking mechanism 200 to activate the emergency unlocking mechanism 200. In normal use, the electronic locking mechanism with the above-described technical solution uses the electronic drive device 100 to actuate its locking assembly 110 to unlock and lock. If the electronic drive device 100 fails, the emergency unlocking key can be used to actuate the emergency unlocking mechanism 200, thereby actuating the locking assembly 110 of the drive device to unlock and lock. The locking device using the electronic locking mechanism can still achieve unlocking and locking functions even in the event of a power outage or damage to the electronic drive device 100, thereby being able to cope with emergency situations. It is understood that the electronic drive device 100 can be a drive device such as an electric cylinder, a solenoid, or a DC motor.

[0037] Reference Figure 1 In some embodiments, the emergency unlocking mechanism 200 includes a limiting bracket 220, a movable bracket 210, and a transmission mechanism 230. A keyhole is provided on the movable bracket 210, and the movable bracket 210 is movably connected to the limiting bracket 220. The movable bracket 210 can move with the emergency key 300 inserted into the keyhole. The transmission mechanism 230 is respectively connected to the movable bracket 210 and the locking assembly 110 of the electronic drive device 100, and is used to transmit the movement of the movable bracket 210 to the locking assembly 110, so that the locking assembly 110 performs an unlocking action or a locking action. The limiting bracket 220 is used to guide and limit the movement of the movable bracket 210 to determine the action flow of the emergency key 300 when unlocking and locking. It can be understood that the transmission mechanism 230 needs to be determined according to the action mode of the locking component 110 when unlocking. If the action mode of the locking component 110 is rotational motion, the transmission mechanism 230 can be a gear set, a crank or a synchronous wheel set, etc.; if the action mode of the locking component 110 is reciprocating motion, the transmission mechanism 230 can be a lever, a cam or a crank, etc.

[0038] Reference Figures 4 to 6According to an embodiment of the present invention, an intelligent grounding wire locking device includes a grounding terminal 400, a locking base 500, an electronic locking mechanism according to the first embodiment of the present invention, and an electronic tag identification device. The grounding terminal 400 is provided with an electronic tag, and locking slots 410 are provided on both sides of the grounding terminal 400. The locking base 500 is provided with a groove for accommodating the grounding terminal 400. Two mounting holes are provided on the sidewalls of the groove, and two locking rods 510 are movably provided in each of the two mounting holes. One end of each locking rod 510 can be inserted into the locking slots 410 of the grounding terminal 400 to secure the grounding terminal 400 in the groove. The electronic locking mechanism is provided in the locking base 500 and can limit the movement of at least one locking rod 510, preventing the locking rod 510 from retracting into the mounting hole and separating from the locking slot 410 of the grounding terminal 400, thereby locking the grounding terminal 400. The electronic tag identification device is arranged in the locking seat 500 and is used to identify the electronic tag on the ground wire head 400. The terminal block 520 is arranged on the locking seat 500 and is electrically connected to the electronic locking mechanism and the electronic tag identification device respectively, and is used to connect to the power supply cable between the power supply and the communication cable between the host computer. According to the intelligent ground wire locking device of the above technical solution, during normal use, the electronic tag identification device identifies the electronic tag on the ground wire head 400. If a match is found, the electronic drive device 100 is driven to perform a locking action and lock the ground wire head 400 on the locking seat 500. To unlock the locking device, the host computer needs to send an unlocking signal through the terminal block 520 to drive the electronic drive device 100 to perform an unlocking action. When the electronic drive device 100 fails or when the system fails and the power is cut off, the emergency key 300 can be used to drive the emergency unlocking mechanism 200 to achieve an emergency unlocking operation. It is understandable that the electronic tag can be a QR code, a specific graphic, an NFC tag or an RFID tag, etc., and the electronic tag identification device can correspond to a code reader, a camera, an NFC reading and writing module or an RFID reading and writing module, etc.

[0039] Reference Figure 6 In some embodiments, the end of the locking rod 510 that can extend into the locking slot 410 is spherical, preventing the locking rod 510 from getting stuck in the locking slot 410 of the ground connector 400 when the ground connector 400 is removed from the locking slot 410. A second compressible elastic member 511 is provided between the locking rod 510 and the locking seat 500. The second compressible elastic member can drive one end of the locking rod 510 into the locking slot 410 of the ground connector 400, securing the locking slot 410 to the locking seat 500. The spherical surface of the locking rod 510 cooperates with the second compressible elastic member 511 to prevent the locking rod 510 from getting stuck in the mounting hole, causing it to become locked.

[0040] Reference below Figures 1 to 6The electronic locking mechanism and the intelligent grounding locking device according to the embodiment of the present invention are described in detail with reference to a specific embodiment. It should be understood that the following description is merely an illustrative description and does not specifically limit the invention.

[0041] Reference Figures 1 to 3 and Figure 5 In this embodiment, the electronic driving device 100 is disposed on the driving mechanism bracket 540. The electronic driving device 100 is a solenoid. The locking component 110 of the electronic driving device 100 is a metal rod. The metal rod is inserted into the solenoid and can reciprocate under the action of the magnetic field of the solenoid. Figure 5 When the metal rod extends, it prevents the locking rod 510 from retracting into the mounting hole, thereby locking the ground wire 400. In this embodiment, the limiting bracket 220 is mounted on the movable bracket 210, and the movable bracket 210 can reciprocate relative to the limiting bracket 220. A rotating block 211 is provided at the lower end of the movable bracket 210, which can rotate relative to the movable bracket 210. The rotating block 211 can rotate relative to the movable bracket 210 with the emergency key 300. Because the locking assembly 110 operates in a reciprocating manner, in this embodiment, the transmission mechanism 230 utilizes a lever principle for transmission. The transmission mechanism 230 includes a paddle 213 and a transmission rod 230, which is movably mounted on the drive mechanism bracket 540 via a rotating shaft. The locking assembly 110 is provided with a paddle plate 111. One end of the transmission rod 230 is provided with a clamp portion, into which the paddle plate 111 extends. The paddle plate 213 is mounted on the rotating block 211 and can rotate with the rotating block 211. Reference Figure 3 When the symmetry axis of the paddle 213 is parallel to the axis of the transmission rod 230, the paddle 213 will not contact the transmission rod 230 during the reciprocating movement of the movable bracket 210. When the symmetry axis of the paddle 213 is perpendicular to the axis of the transmission rod 230, the paddle 213 can move the transmission rod 230 when moving up and down with the movable bracket 210, driving the jaws of the transmission rod 230 to move the paddle plate 111, thereby driving the locking assembly 110 to extend or retract. Figure 2The limiting bracket 220 has a groove that matches the shape of the paddle 213, preventing the paddle 213 from reciprocating up and down without being rotated to the proper angle, causing unlocking or locking failure. A limiting pin 212 is provided on the movable bracket 210, and a limiting groove 310 is provided on the emergency key 300 that matches the limiting pin 212. The limiting pin 212 can move along the limiting groove 310, limiting the rotational travel of the emergency key 300 and facilitating its use. A top ball 213 is provided within the movable bracket 210, with a compression spring interposed between the top ball 213 and the movable bracket 210. The rotating block 211 has two grooves that match the top ball 213. The top ball 213 is engaged by the compression springs and snaps into the grooves on the rotating block 211, preventing the rotating block 211 from rotating freely when the emergency key 300 is not inserted. A first compressible elastic member 240 is provided between the movable bracket 210 and the limiting bracket 220, driving the movable bracket 210 away from the limiting bracket 220. In this embodiment, the first compression elastic member 240 is a compression spring.

[0042] According to the electronic locking mechanism of the above embodiment, to unlock, the emergency key 300 is first rotated so that the symmetric axis of the paddle 213 is parallel to the direction of the movable rod 232, the emergency key 300 is pressed down, and the emergency key 300 is then rotated again so that the symmetric axis of the paddle 213 is perpendicular to the direction of the movable rod 232. Finally, the emergency key 300 is lifted to move the paddle 213 upward and move the movable rod 232, causing the movable rod 232 to retract the locking assembly 110. To lock, the emergency key 300 is rotated so that the symmetric axis of the paddle 213 is perpendicular to the direction of the movable rod 232, and the emergency key 300 is pressed down again to move the paddle 213 downward and move the transmission rod 230 downward, driving the locking assembly 110 to extend.

[0043] Reference Figures 4 to 6 In this embodiment, the electronic tag is an RFID tag printed on the back of the ground connector 400. An RFID reader module 530 is located within the recess to identify the RFID tag. The terminal block 520 is located below the locking base 500. The locking rod 510 is composed of two cylinders of different diameters. The spherical surface is attached to the end face of the larger cylinder. The smaller cylinder, facing away from the junction of the two cylinders, is provided with a retaining spring 512 to prevent the locking rod 510 from falling out of the mounting hole. In this embodiment, the second compressible elastic member 511 is a compression spring.

[0044] According to the embodiment of the present invention, the intelligent grounding locking device has an electronic locking mechanism according to the embodiment of the present invention. It can intelligently manage the ground wire head by identifying the electronic tag on the ground wire head. At the same time, the emergency unlocking device of the electronic locking mechanism can realize emergency locking and emergency unlocking of the ground wire head, and can deal with emergency situations such as system power failure or failure of the electronic drive device.
