Abstract

The present invention relates to a multi charging device enabled by current and voltage control and, most particularly, to a multi charging device enabled by current and voltage control being configured to include a main charging unit being capable of changing a charging speed, and an auxiliary charging unit being connected to the main charging unit by a wired connection and being incapable of changing the charging speed, wherein the main charging unit includes a power input module being supplied with power from an external power source, a voltage/current control module controlling voltage and current of the power being delivered from the power input module so as to vary the voltage and current, a variable charging module being supplied with voltage/current in accordance with a size that is varied by the voltage/current control module and performing wireless charging of devices, and a power output module being supplied with specific voltage/current controlled by the voltage/current control module and supplying power to the auxiliary charging unit, and wherein the auxiliary charging unit includes a non-variable charging module being supplied with the specific voltage/current from the power output module and performing wireless charging of devices.

Claims

1. A multi charging device enabled by current and voltage control being configured to include a main charging unit being capable of changing a charging speed, and at least one auxiliary charging unit being connected to the main charging unit by a wired connection and being incapable of changing the charging speed,

wherein the main charging unit comprises:

a power input module being supplied with power from an external power source,

a voltage/current control module controlling voltage and current of the power being delivered from the power input module so as to vary the voltage and current,

a variable charging module being supplied with voltage/current in accordance with a size that is varied by the voltage/current control module and performing wireless charging of devices, and

a power output module being supplied with specific voltage/current controlled by the voltage/current control module and supplying power to the auxiliary charging unit, and

wherein the at least one auxiliary charging unit comprises;

a non-variable charging module being supplied with the specific voltage/current from the power output module and performing wireless charging of devices.

2. The device of claim 1, wherein the main charging unit comprises:

a first docking station holding a target device and having a transmitting unit installed therein;

a first bottom supporting unit coupled with the first docking station so as to provide support and supporting a bottom surface;

a first cable connecting part being formed on one side of the first bottom supporting unit and being connected to a cable provided to connect the main charging unit and the auxiliary charging unit; and

a power cable being extracted from another side of the first bottom supporting unit and receiving the power being supplied to the power input module from a power source.

3. The device of claim 2, wherein the first docking station has a flat plane surface so as to hold a device, and wherein the flat plane surface forms a predetermined inclination angle with the first bottom supporting unit.

4. The device of claim 1, wherein the auxiliary charging unit comprises:

a second docking station holding a target device and having a transmitting unit installed therein;

a second bottom supporting unit coupled with the second docking station so as to provide support and supporting a bottom surface; and

a second cable connecting part being formed on one side of the second bottom supporting unit and being connected to a cable provided to connect the main charging unit and the auxiliary charging unit.

5. The device of claim 4, wherein the second docking station is perpendicular to the second bottom supporting unit or forms a predetermined inclination angle with the second bottom supporting unit.

6. The device of claim 5, wherein the second docking station holds a wearable device.

7. The device of claim 1, wherein a current being supplied through the power input module is branched to a charging current of the main charging unit and a charging current of the auxiliary charging unit by the voltage/current control module, and

wherein each type of charging current is independently controlled.
