The front wheel 173 may be moved along the guide groove 14 so that the personal mobility device 170 may be moved to the fixing column 20 in which the first charging unit 30 is provided. As the guide member 12 supports both lateral surfaces of the front wheel 173, the personal mobility device 170 may be kept in an upright state.

[0095] As shown in FIG. 1, wireless charging may be performed in a state where the second charging unit 70 is in contact with the first charging unit 30 or spaced apart from the first charging unit 30 within a preset distance. The transmission coil 60 provided with power through the transmission controller 50 may generate a magnetic field for power generation. The magnetic field of the transmission coil 60 may be transmitted to the reception coil 100 to be converted into power by the reception controller 90. The converted power may be transmitted to the battery 176 to charge the battery 176.

[0096] Since the battery 176 of the personal mobility device 170 is wirelessly charged, the battery has versatility regardless of a shape of a wired charging port and thus may provide a charging docking station that is capable of responding to devices of all manufactures.

[0097] Meanwhile, when the first charging unit 30 is operating, the display unit 140 may be operated to display that the personal mobility device 170 is being charged.

[0098] The wireless charging of the personal mobility device 170 may be implemented at the same time when it is mounted on the support unit 10. Accordingly, the waiting time when the personal mobility device can be used again after returning it may be shortened so that similar device rental revenue may be earned with a smaller number of personal mobility devices 170, compared to the prior art.

[0099] In addition, the wireless controller 130 may identify the first charging unit 30 being charged among the plurality of first charging units 30, and may transmit data to the remote server 160.

[0100] Accordingly, the user may easily grasp how many personal mobility devices 170 are in a use standby state at which location through the terminal 200, thereby improving use convenience.

[0101] The embodiments are described above with reference to a number of illustrative embodiments thereof. However, the present disclosure is not intended to limit the embodiments and drawings set forth herein, and numerous other modifications and embodiments can be devised by one skilled in the art. Further, the effects and predictable effects based on the configurations in the disclosure are to be included within the range of the disclosure though not explicitly described in the description of the embodiments.
