The detection device 26 of the electrical device 200 stores a reference range. In at least one exemplary embodiment, the reference range is from 1 meter to 3 meters. The detection device 26 is configured to detect a distance between the electrical device 200 and the charging device 100 . The detection device 26 is further configured to determine whether the distance is within the reference range.

When the detection device 26 is mounted in the electrical device 200 , and if it is determined that the distance is within the reference range, the second communication device 32 of the electrical device 200 is configured to communicate with the first communication device 30 of the charging device 100 . The first communication device 30 is configured to send a first control signal to the processing device 40 after communicating with the second communication device 32 . The processing device 40 is configured to output a driving signal to the driving device 50 after receiving the first control signal. FIG. 3 illustrates that the driving device 50 is configured to provide a pushing force F 1 to push the first connector 10 to move after receiving the driving signal, thereby enabling the first connector 10 to extend from the opening 62 of the case 60 to couple to the second connector 12 (shown in FIG. 1 ). The control device 20 includes a frame 22 and an elastic member 24 , and the elastic member 24 is fixedly coupled between the frame 22 and the first connector 10 . In one exemplary embodiment, the control device 20 further includes a first magnet (not shown) and a second magnet (not shown), the first magnet is disposed on the frame 22 , the second magnet is disposed on the first connector, and the first magnet and the second magnet are isotropically attracted to each other. A mutual attraction magnetic force is generated between the frame 22 and the first connector 10 to pull the first connector 10 back to the original position. The first connector 10 is in a second position when being coupled to the second connector 12 . The elastic member 24 elastically deforms when an elastic force is provided by the second connector 12 being coupled to the first connector 10 . The securing device 52 is configured to secure the second connector 12 to the first connector 10 after the first connector 10 is coupled to the second connector 12 .

The processing device 40 is configured to output the driving signal to the driving device 50 after receiving the second control signal. The driving device 50 is configured to provide the pushing force F 1 to push the first connector 10 to move after receiving the driving signal, thereby enabling the first connector 10 to extend from the opening 62 of the case 60 to couple to the second connector 12 . The first connector 10 is in the second position when being coupled to the second connector 12 . The elastic member 24 is elastically deformed to form the elastic force after the second connector 12 is coupled to the first connector 10 . The securing device 52 is configured to secure the second connector 12 to the first connector 10 after the first connector 10 is coupled to the second connector 12 .

In at least one exemplary embodiment, each of the pushing force and the pulling force from the device 50 is greater than the elastic restoring force of the elastic member 24 when elastically deformed.

In one exemplary embodiment, the processing device 40 cannot output the driving signal to the driving device 50 after the second connector 12 is coupled to the first connector 10 . The driving device 50 cannot provide the pushing force F 1 without receiving the driving signal. In another exemplary embodiment, the second connector 12 disconnects from the first connector 10 after the electrical device 200 finished being charged, thus, the processing device 40 cannot output the driving signal to the driving device 50 . The driving device 50 cannot provide the pushing force F 1 without receiving the driving signal.

The elastic member 24 can restore to release the elastic deformation, and the force of restoration pulls the first connector 10 to be the first position after the second connector 12 disconnects from the first connector 10 .
