[0033] See also Figures 1 to 6 A charging gun sealed electronic lock includes a shell 100, a locking rod 200, a driving motor 300 and a micro switch 400. The shell 100 has a hollow and closed structure, and a locking hole 110 is opened on the side wall of the shell 100, and a first sealing ring 120 is arranged at the lock hole 110. The locking rod 200, the driving motor 300 and the micro switch 400 are respectively arranged inside the shell 100, and a main gear 310 is arranged at the output end of the driving motor 300. The locking rod 200 is connected to the main gear 310. When the driving motor 300 drives the main gear 310 to rotate, the main gear 310 will drive the locking rod 200 to move along the locking hole 110, and the locking rod 200 will act on the micro switch 400 when moving.

[0034] Specifically, in this embodiment, the lock rod 200, the drive motor 300 and the micro switch 400 are respectively installed in the enclosed space of the housing 100, and a main gear 310 is provided at the output end of the drive motor 300. The lock rod 200 is directly connected to the main gear 310, so that when the drive motor 300 drives the main gear 310 to rotate, the main gear 310 can directly drive the lock rod 200 to extend or retract from the lock hole 110 of the housing 100, thereby realizing the locking and unlocking of the electronic lock; at the same time, when the lock rod 200 extends outward from the lock hole 110 to lock, the lock rod 200 acts on the micro switch 400, so that the micro switch 400 transmits a signal. The signal is given to the external power supply, and the external power supply starts to supply power. When the lock rod 200 retracts inward to unlock, the lock rod 200 will also be separated from the micro switch 400, and the trigger state of the micro switch 400 will be released, and the external power supply will stop supplying power, so that the user can safely unplug the charging gun to ensure safety performance. In addition, the main gear 310 is directly connected to the lock rod 200 through transmission, and the lock rod 200 and the micro switch 400 are linked, so as to reduce the number of transmission connection components compared to the electronic lock in the prior art. Due to the reduction of components, the overall structure of the electronic lock in this embodiment can be simpler and more convenient during production and assembly.

[0035] In order to enable the electronic lock to be applied to various places, the interior of the shell 100 is a hollow enclosed space, and a first sealing ring 120 is provided at the lock hole 110. The first sealing ring 120 is sleeved on the lock rod 200 and moves with the lock rod 200. The enclosed space and the first sealing ring 120 can achieve a comprehensive sealing of the interior of the shell 100, thereby improving the waterproof and dustproof effect of the electronic lock, so that the electronic lock can work in an IP67 environment, thereby meeting the use requirements of the electronic lock.

[0036] See also Figure 3 and Figure 4 In order to realize the locking and unlocking functions of the lock rod 200 and to work in conjunction with the micro switch 400, in this embodiment, a pressing portion 210 is provided at the end of the lock rod 200, and a main rack 220 is provided at the side of the lock rod 200, wherein the main rack 220 at the side of the lock rod 200 directly meshes with the main gear 310 of the drive motor 300. When the drive motor 300 drives the main gear 310 to rotate, the main gear 310 and the main rack 220 are engaged with each other. 0, the main gear 310 will move with the main rack 220, and when the main rack 220 moves, the locking rod 200 will extend outward from the lock hole 110 or retract inward, when the locking rod 200 extends outward from the lock hole 110, it will be clamped and fixed with the charging gun, and the pressing part 210 will press the micro switch 400, thereby transmitting the signal to the external power supply, finally realizing the locking and unlocking functions of the electronic lock, and realizing the linkage with the micro switch.

[0037] See also Figure 2 , Figure 3 and Figure 5 In order to avoid the situation where the lock rod 200 cannot be retracted due to a malfunction of the electronic lock, in this embodiment, a manual unlocking member 500 is further provided inside the housing 100. Specifically, a sub-gear 320 is further provided at the output end of the drive motor 300, and the manual unlocking member 500 is directly connected to the sub-gear 320. When the electronic lock fails and the lock rod 200 cannot be retracted, the user can pull the manual unlocking member 500, and when the manual unlocking member 500 is pulled, it will drive the sub-gear 320 to rotate. When the sub-gear 320 rotates, it will cause the main gear 310 to rotate in the opposite direction. The reverse rotation of the main gear 310 will cause the lock rod 200 to retract inward, thereby realizing manual unlocking of the electronic lock and ensuring the safety performance of the electronic lock.

[0038] In order to manually unlock the electronic lock, the manual unlocking member 500 in this embodiment includes a pulling part 510, a secondary rack 520 and a pull rope 530. The two ends of the pulling part 510 are respectively connected to the secondary rack 520 and the pull rope 530, and the secondary rack 520 is integrally connected with the pulling part 510. The stability and firmness between the secondary rack 520 and the pulling part 510 can be ensured through the one-piece molding connection, and the secondary rack 520 will mesh with the secondary gear 320. One end of the pull rope 530 extends outward from the side wall of the shell 100.

[0039] When the electronic lock is working normally, the driving motor 300 will simultaneously drive the main gear 310 and the sub-gear 320 to rotate forwardly. When the main gear 310 and the sub-gear 320 rotate forwardly, the locking rod 200 will extend outward. When a fault occurs and the driving motor 300 cannot work, the user can pull the pull rope 530 extending to the outside of the shell 100. When pulling, the pulling part 510 will move with the sub-rack 520. When the sub-rack 520 moves, it will drive the sub-gear 320 to rotate in the opposite direction. At the same time, the sub-gear 320 will rotate the main gear 310 in the opposite direction, so that the locking rod 200 can be manually retracted into the shell 100, thereby realizing manual unlocking of the electronic lock. The pull rope 530 can be convenient for the user to operate, thereby facilitating manual unlocking of the electronic lock.

[0040] In order to make the connection between the pulling part 510 and the pull rope 530 firm, the pulling part 510 and the pull rope 530 can be connected by an integral molding, and the integral connection can ensure the firmness of the connection between the pulling part 510 and the pull rope 530, so as to ensure that the pull rope 530 can pull the pulling part 510 to realize the manual unlocking function;

[0041] Of course, a detachable connection can also be adopted between the pulling part 510 and the pull rope 530. For example, when a detachable connection is adopted, a groove 511 is provided on the pulling part 510, and a pulling hole 512 is opened at one end of the groove 511, one end of the pull rope 530 is inserted into the groove 511 from the pulling hole 512 to form a pull rope head 531, and the other end is extended outward from the side wall of the shell 100. Through the detachable connection, the pull rope 530 can be replaced in the event of aging and breakage of the pull rope 530. At the same time, the groove 511 provided in the pulling part 510 can effectively prevent the pull rope 530 from being knotted or entangled with other parts, thereby ensuring that the electronic lock can be manually unlocked smoothly through the pull rope 530 when a fault occurs. In order to ensure that the connection between the pull rope 530 and the pulling part 510 is more stable, the size of the pull rope head 531 will be larger than the aperture of the pulling hole 512, so as to ensure the stability of the connection and prevent the pull rope 530 from being detached from the pulling part 510.

[0042] See also Figure 1 and Figure 6 Since the pull cord 530 needs to extend out of the shell to facilitate the user to pull it, in order to seal the pull cord 530 extending out of the shell 100, a first seal 130 is provided at the penetration point of the pull cord 530. The penetration point between the pull cord 530 and the shell 100 is sealed by the first seal 130, thereby achieving the sealing of the inside of the shell 100, ensuring the sealing of the inside of the shell 100, and then improving the waterproof and dustproof effect of the electronic lock.

[0043] In addition, since the micro switch 400 and the drive motor 300 of the electronic lock need to be powered on to operate normally, the micro switch 400 and the drive motor 300 will be connected to the external power supply through the wire 600 respectively, and the wire 600 needs to be inserted into the shell 100. In order to seal the penetration point of the wire 600, in this embodiment, a second sealing member 140 is provided at the penetration point of the wire 600. The second sealing member 140 can also achieve sealing of the interior of the shell 100 and ensure the sealing of the interior of the shell 100, thereby improving the waterproof performance of the electronic lock.

[0044] Finally, see Figure 6In order to facilitate the assembly of the electronic lock, the housing 100 in this embodiment includes a plastic shell 150 and a bottom cover 160, and the plastic shell 150 is provided with a sealing groove 151, and a second sealing ring (not shown in the figure) is provided in the sealing groove 151. After the lock rod 200, the drive motor 300, the micro switch 400, and the manual unlocking member 500 are respectively assembled into the housing 100, the plastic shell 150 and the bottom cover 160 are covered, and the plastic shell 150 and the bottom cover 160 can be sealed by the second sealing ring in the sealing groove 151 after covering, so as to achieve comprehensive sealing of the electronic lock and ensure the sealing performance of the electronic lock, so that the electronic lock can be applied to different occasions and the electronic lock can work in an IP67 environment, so as to meet the use requirements of the electronic lock. Of course, in order to achieve sealing between the plastic shell 150 and the bottom cover 160, the plastic shell 150 and the bottom cover 160 can also be sealed by heat welding, laser welding, ultrasonic welding, and the sealed covering method can also be sealed by other methods, which are not limited here.
