When the driving motor 221 drives the slider 223 to move, it drives the fastening portion 202 to rotate, and when the fastening portion 202 rotates to a certain position, the locking hole 101 can be locked.

[0026] In this embodiment, as a specific solution, the driving mechanism 22 further includes a slider locking assembly 23. The slider locking assembly 23 includes a slider lock 231, an elastic element 232, a ball 233, and a screw sleeve 225 provided on the slider 223. The screw 222 passes through the screw sleeve 225, and the screw 222 is provided with a groove structure 226.

When the slider lock 231 moves on the outer wall of the screw sleeve 225, it moves along the guiding protrusion 227.

[0031] In this embodiment, as a specific solution, the socket 1 further includes a socket positive conductor 12, a socket negative conductor 13, an insulator 14, and a plurality of socket signal elastic pieces 15. The plug 2 is provided with a matching plug positive conductor 26, a plug negative conductor 27, and a plurality of plug signal elastic pieces 28. The socket 2 is further provided with a plurality of signal rings 29. Each of the plurality of plug signal elastic pieces 28 is fixedly connected to one of the plurality of signal rings 29. When the plug 2 and the socket 1 are mated, each of the plurality of socket signal elastic pieces 14 and the plurality of plug signal elastic pieces 28 is conducted through the signal ring 29 one by one.

[0032] In this embodiment, as a more specific solution, the plug 2 is provided with four signal coils 29, namely signal coil one, signal coil two, signal coil three, and signal coil four. There are four plug signal elastic pieces 28, namely plug signal elastic piece one, plug signal elastic piece two, plug signal elastic piece three, and plug signal elastic piece four. Among them, plug signal elastic piece one is connected to signal coil one and does not contact other signal coils. Plug signal elastic piece two is connected to signal coil two and does not contact other signal coils. Plug signal elastic piece three is connected to signal coil three and does not contact other signal coils. Plug signal elastic piece four is connected to signal coil four and does not contact other signal coils; that is, the plug signal elastic pieces 28 are fixedly connected to one of the signal coils 29 one by one and do not contact other signal coils. There are also four socket signal elastic pieces 15, namely socket signal elastic piece one, socket signal elastic piece two, socket signal elastic piece three, and socket signal elastic piece four. When the plug 2 and the socket 1 are inserted into each other, socket signal elastic piece one contacts signal coil one and conducts with plug signal elastic piece one. Socket signal elastic piece two contacts signal coil two and conducts with plug signal elastic piece two, and so on.

[0033] In this embodiment, as a specific solution, the width of each signal coil 29 is about 4 mm. The plug signal elastic piece 28 and the socket signal elastic piece 15 are conducted through the signal coil 29 as an intermediate conductive member. Both have about 2 mm of movable space, which can adapt to the vibration environment during vehicle operation. This is because in this application, the plug 2 is arranged in the battery swapping cabinet, and the socket 1 is arranged on the battery of the two-wheeled vehicle. A plug with the same structure as the plug 2 in the battery swapping cabinet is also arranged on the two-wheeled vehicle for the battery to be assembled on the two-wheeled vehicle. Therefore, the movable space of the signal elastic pieces of the plug 1 and the socket 2 in the battery swapping cabinet is also applicable to the movable space of the signal elastic pieces of the plug and the socket 2 on the two-wheeled vehicle.

[0034] In this embodiment, as a more specific solution, the two adjacent signal coils 29 are separated by an insulating coil 210.

[0035] The working principle of the present invention is as follows: After the plug 2 and the socket 1 are inserted into each other, the drive motor 221 receives the insertion completion signal, and the motor rotates forward, driving the screw 222 to rotate. The screw 222 drives the slider 223 to move ( Figure 8 to the left in the figure), and the slider 223 drives the handle 203 to rotate forward, so that the fastening part 202 fastens the locking hole 101, realizing the locking of the plug 2 and the socket 1. When the locking state is reached, the slider 223 touches the locking travel switch 24 at the same time, and the drive motor 221 stops rotating; When the drive motor 221 receives the unlocking signal, the motor rotates reversely, driving the screw 222 to rotate reversely. The screw 222 drives the slider 223 to move reversely ( Figure 8When moving to the right in the figure), the slider 223 drives the handle 203 to rotate in the reverse direction, causing the fastening part 202 to disengage from the locking hole 101, realizing the unlocking of the plug 2 and the socket 1. When the unlocking state is reached, the slider 223 touches the unlocking travel switch 25 at the same time, driving the motor 221 to stop rotating, and then separating the plug 2 and the socket 1.

[0036] In special cases, such as when maintenance is required, pull the steel wire rope from the rope installation part 235 in the direction of the elastic element 232 ( Figure 8 Pulling to the right in the figure), the slider lock 231 compresses the elastic element 232. Under the action of the pulling force, the slider 223 also has a force in the direction of compressing the elastic element 232 ( Figure 8 A force to the right in the figure), this force is transmitted to the ball 233, prompting the ball 233 to fall into the groove structure 226 of the screw 222. At this time, the slider 223 and the screw 222 are in the unlocked state, and the slider 223 can move relative to the screw 222, thereby driving the handle 203 to rotate, achieving the purpose of rapid unlocking; under normal conditions, under the action of the elastic element 232, the convex structure 234 of the slider lock 231 presses the ball 233, and the ball 233 presses on the edge of the screw between two adjacent groove structures 226 of the screw 222, and the ball 233 locks the slider 223 and the screw 222, that is, the slider 223 is in the locked state.

[0037] It should be noted that when the drive motor works during locking and unlocking, the slider 223 and the screw 222 are always in the locked state, and only when the steel wire rope is pulled will the ball 233 fall into the groove structure 226 of the screw.

[0038] The foregoing description of the specific exemplary embodiments of the present invention is for purposes of illustration and exemplification. These descriptions are not intended to limit the invention to the precise forms disclosed, and it is obvious that many changes and variations are possible in light of the above teachings. The purpose of selecting and describing the exemplary embodiments is to explain the specific principles of the present invention and its practical applications, so that those skilled in the art can implement and utilize various different exemplary embodiments of the present invention, as well as various different selections and changes.
