Abstract

The present invention relates to a charging system for personal mobility devices and, more particularly, may includes: support units provided with slots into which wheels of personal mobility devices are mounted; first charging units which are installed toward the personal mobility devices and generate magnetic fields for wireless charging; and second charging units which are mounted onto the personal mobility devices, and which covert the magnetic fields, received via the first charging units, into electric power to charge the batteries provided in the personal mobility devices.

Claims (61)

1 . A charging system for a personal mobility device that includes a wheel, a battery and a charger configured to convert a magnetic field into electricity for charging the battery, the charging system comprising:

a support structure comprising a groove in which the wheel of the personal mobility device is seated;

a fixing column extending upward from one side of the support structure and arranged to face the personal mobility device when the wheel of the personal mobility device is seated in the support structure;

a magnetic field generator disposed at a position on the fixing column at a height equivalent to a height of the charger of the personal mobility device and configured to generate the magnetic field for wireless charging the personal mobility device; and

a wireless controller configured to communicate with a movement controller provided in the personal mobility device,

wherein the movement controller is configured to measure whether the personal mobility device is being charged and transmit the measured value to the wireless controller.

2 . The charging system for the personal mobility device of claim 1 , wherein the support structure comprises a guide member forming the groove recessed upward, and one side of the guide member is disposed toward the fixing column and the other side thereof extend in a direction getting away from the fixing column.

3 . The charging system for the personal mobility device of claim 1 , further comprising:

a mounting sensor configured to measure whether the wheel is seated on the support structure.

4 . The charging system for the personal mobility device of claim 3 , further comprising:

wherein the wireless controller is configured to communicate with the mounting sensor and the magnetic field generator, and the wireless controller is further configured to control an operation of the magnetic field generator.

5 . The charging system for the personal mobility device of claim 4 , wherein the wireless controller is configured to send data to a remote server that determines whether the personal mobility device is mounted and whether it is being charged.

6 . The charging system for the personal mobility device of claim 1 , wherein the magnetic field generator comprises,

a first housing fixed to the fixing column;

a transmission controller disposed inside the first housing; and

a transmission coil disposed inside the first housing and connected with the transmission controller.

7 . The charging system for the personal mobility device of claim 6 , wherein the first housing comprises,

a first housing body fixed to the fixing column;

a first core member fixed to the first housing body with the transmission controller interposed therebetween; and

a first cover member fixed to the first core member with the transmission coil interposed therebetween.

8 . The charging system for the personal mobility device of claim 1 , wherein the charger of the personal mobility device comprises,

a second housing fixed to the personal mobility device;

a reception controller disposed inside the second housing; and

a reception coil disposed inside the second housing and connected with the reception controller.

9 . The charging system for the personal mobility device of claim 8 , wherein the second housing comprises,

a second housing body fixed to the personal mobility device;

a second core member fixed to the second housing body with the reception controller interposed therebetween; and

a second cover member fixed to the second core member with the reception coil interposed therebetween.

10 . A charging system for a personal mobility device that includes a wheel, a battery and a charger configured to convert a magnetic field into electricity for charging the battery, the charging system comprising:

a magnetic field generator disposed at a height equivalent to a height of the charger of the personal mobility device and configured to generate a magnetic field for wireless charging the personal mobility device;

a charging measurement device configured to measure whether the personal mobility device is being charged; and

a wireless controller configured to receive a measured value of the charging measurement device and wirelessly transmit the measured value to a remote server, the remote server configured to receive data from the wireless controller and to determine whether the personal mobility device is mounted and to determine whether the personal mobility device is being charged based on the data,

wherein the wireless controller is configured to communicate with a movement controller provided in the personal mobility device, and

wherein the movement controller is configured to measure whether the personal mobility device is being charged and transmit the measured value to the wireless controller.

11 . The charging system for the personal mobility device of claim 10 , further comprising:

a support structure comprising a groove in which the wheel of the personal mobility device is seated; and

12 . The charging system for the personal mobility device of claim 10 , wherein the support unit, the fixing column and the magnetic field generator form one module, and a plurality of modules are disposed.

13 . The charging system for the personal mobility device of claim 11 , further comprising:

a display unit disposed on the fixing column and configured to be luminescent with a preset color by being operated based on a control signal of the wireless controller and display a charging state of the personal mobility device.

14 . The charging system for the personal mobility device of claim 11 , wherein the remote server is provided with presence of the personal mobility device that is mounted and being charged, and transmits a location and a charging state of the personal mobility device to a user terminal.

15 . A charging system for a personal mobility device that includes a wheel, a battery and a charger configured to convert a magnetic field into electricity for charging the battery, the charging system comprising:

a support structure comprising a groove in which the wheel of the personal mobility device is seated;

a magnetic field generator disposed at a height equivalent to a height of the charger of the personal mobility device and configured to generate the magnetic field for wireless charging; and

a wireless controller configured to communicate with a movement controller provided in the personal mobility device,

wherein the movement controller is configured to measure whether the personal mobility device is being charged and transmit the measured value to the wireless controller.

16 . The charging system for the personal mobility device of claim 15 , further comprising:

a mounting sensor configured to measure whether the wheel is seated on the support unit.

17 . The charging system for the personal mobility device of claim 16 ,

wherein the wireless controller is configured to receive a measured value of a charging measurement unit and wirelessly transmit the measured value to a remote server, and the remote server is further configured to receive data from the wireless controller and to determine whether the personal mobility device is mounted and to determine whether the personal mobility device is being charged based on the data.

18 . The charging system for the personal mobility device of claim 17 , wherein the charging measurement unit is connected with the wireless controller and the movement controller.

19 . The charging system for the personal mobility device of claim 15 , further comprising:

wherein the magnetic field generator comprises,
