[0051] like Figures 1 to 15 As shown, in an exemplary embodiment of this utility model, an electronic lock is disclosed. The electronic lock includes: a housing 11, a movable block 2, a locking pin 14, a driving device 5, a pair of detection terminals 4, and a conductive element 3. The movable block 2 is movably mounted in the housing 11. The locking pin 14 is fixed to the movable block 2 and extends from the housing 11, and is capable of moving with the movable block 2 between a locked position and an unlocked position. The driving device 5 is mounted in the housing 11 and is used to drive the movable block 2 and the locking pin 14 to move between the locked and unlocked positions. The pair of detection terminals 4 are fixed to the inner side of the housing 11. The conductive element 3 is mounted on the movable block 2 so as to be able to move with the movable block 2. When the movable block 2 is moved to the locked position, the conductive element 3 is moved to a bridging position where it simultaneously makes electrical contact with the pair of detection terminals 4, thereby electrically connecting the pair of detection terminals 4.
[0052] like Figures 1 to 15 As shown in the illustrated embodiment, when the locking pin 14 is moved to the locked position, the locking pin 14 is adapted to engage with a pin hole on the charging gun (not shown) to lock the charging gun to the charging socket (not shown). When the locking pin 14 is moved to the unlocked position, the locking pin 14 disengages from the pin hole on the charging gun to allow the charging gun to be pulled out of the charging socket.
[0053] like Figures 1 to 15 As shown in the illustrated embodiment, when the moving block 2 is moved to the locked position, the conductive element 3 is moved to the bridging position. When the moving block 2 is not moved to the locked position, the conductive element 3 is not in contact with at least one of the pair of detection terminals 4 (e.g., the conductive element 3 is in contact with only one of the pair of detection terminals 4 or not in contact with either pair of detection terminals 4), so that the pair of detection terminals 4 are electrically disconnected.
[0054] like Figures 1 to 15 As shown in the illustrated embodiment, a mounting hole 20 is formed on the movable block 2, and the conductive element 3 is a lower ball 32 that is rotatably mounted in the mounting hole 20. A portion of the lower ball 32 protrudes from the lower opening of the mounting hole 20 for electrical contact with a pair of detection terminals 4.
[0055] However, please note that the conductive component 3 of this invention is not limited to the lower ball 32 shown in the figure. It can also be a non-rolling component with a smooth arc-shaped contact bottom surface to reduce sliding friction.
[0056] likeFigures 1 to 15 As shown in the illustrated embodiment, the electronic lock further includes an upper ball 31 and a resilient member 33. The upper ball 31 is rollably installed in the mounting hole 20 of the moving block 2.

The upper ball 31 and the lower ball 32 self-rotate in the mounting hole 20 during movement with the moving block 2. In the illustrated embodiment, the resilient member 33 can be a coil spring.
[0057] As shown in the illustrated embodiment, when the moving block 2 is moved to the locked position, the lower ball 32 is moved to the bridging position. When the moving block 2 is not moved to the locked position, the lower ball 32 is not in contact with at least one of the pair of detection terminals 4, so that the pair of detection terminals 4 is in an electrically separated state.

When the lower ball 32 is moved to the bridging position, the lower ball 32 is in electrical contact with the contact ends 41 of the pair of detection terminals 4 at the same time. Figures 1 to 15
[0061] As shown in the illustrated embodiment, in the illustrated embodiment, the spacing between the contact ends 41 of the pair of detection terminals 4 is less than the diameter of the lower ball 32, so that the lower ball 32 can be in electrical contact with the contact ends 41 of the pair of detection terminals 4 at the same time. The detection terminal 4 further has an extension 42 connected to the contact end 41, and the spacing between the extensions 42 of the pair of detection terminals 4 is greater than the diameter of the lower ball 32, so that the lower ball 32 cannot be in electrical contact with the extensions 42 of the pair of detection terminals 4 at the same time. Figures 1 to 15
