5 is a view for explaining a method of mounting a wearable device battery according to another embodiment of the present invention.

Referring to FIG. 5, the wearable device of the wristwatch type according to an embodiment of the present invention may include a main body 500 and a wristband 501 detachably attached to one side of the main body 500. It should be noted that although not shown in FIG. 5, the second wristband 202 of FIG. 2 is connected to the other side of the main body 500. Here, a wearable device body 500 may include a predetermined power plug input terminal 505 for receiving an external power source, and one end of the wristband 501 may be connected to one end of the main body 500 to supply power to the main body 500 A power plug 510 may be provided.

Particularly, the wireless power receiving means 530 mounted on one side of the wristband 501 can receive the power from the external wireless power transmission device and charge the battery pack 520 built in the wristband 501.

Here, as a technique used in the wireless power transmission from the wireless power transmission apparatus to the wireless power reception means 530, any one of an inductive coupling scheme, a resonance scheme, and an RF scheme can be used.

Inductive coupling is a non-contact electromagnetic induction technology widely used in portable terminals. When two coils are connected to a server and a current is supplied to one coil, magnetic flux generated in the coils causes electromotive force Is a technique for transmitting power using a phenomenon.

The resonance method is an electromagnetic resonance (electromagnetic resonance) method, which utilizes an electric field or a magnetic field instead of using an electromagnetic wave or a current.

RF technology is a technology that utilizes the fact that energy can be directly transmitted and received in the form of a radio wave, and is a technique of converting an AC radio wave transmitted from a transmitter into a DC from a receiver.

6 is a flowchart illustrating a method of controlling power of a wearable device using a detachable wristband on which a battery pack is mounted according to an embodiment of the present invention.

Referring to FIG. 6, the controller 180 can detect that the wristband on which the charged battery pack is mounted is connected to the main body while the wristband on which the battery pack is mounted is removed from the main body of the wearable device (S600 to S601 ). Here, when the wristband is removed from the main body, the controller 180 may drive the main body using the auxiliary battery built in the main body. Here, the auxiliary battery is a rechargeable battery, and the discharged voltage according to the control signal of the controller 180 can be charged through a power source from the outside. For example, the battery mounted on the wristband can be an external power source for charging the auxiliary battery.

The controller 180 controls the power supply unit 190 to supply power to the wearable device body by receiving power from the battery pack mounted on the wristband (S603).

When the wristband is removed from the main body, the control unit 180 releases the base-blocked function and charges the auxiliary battery built in the main body using the power supplied through the battery pack (S607). Here, the blocked functions may include functions of relatively high battery consumption such as a multimedia playback function, an outgoing call function, and a game function.

Thereafter, depending on the use of the wearable device, the battery pack mounted on the wristband may be discharged or the charge level may be lowered. At this time, the user can remove the wristband from the body for charging the battery pack.

If it is detected that the wristband on which the battery pack is mounted is removed from the main body, the control unit 180 may control power to be supplied through the auxiliary battery built in the main body (S609 to S611).

Subsequently, the control unit 180 can block the use of some battery-consuming functions and control so that only predetermined basic functions can be performed (S613).

It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

Accordingly, the above description should not be construed in a limiting sense in all respects and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
