1 is a block diagram of a portable wireless device having a wireless charging function using motion detection according to an embodiment of the present invention.

Referring to FIG. 1, a portable wireless device (hereinafter referred to as a portable wireless device) 100 having a wireless charging function using motion detection according to an embodiment of the present invention includes a battery 110, And may be configured to include a resonator 120, a wireless power receiving module 130, a wireless power transmitting module 140, a wireless power transmitting and receiving diverting module 150, a gyro sensor 160 and a control module 170 .

The portable wireless device 100 may be a device such as a smart phone or a tablet PC. The portable wireless device 100 receives and wirelessly receives wireless power from a dedicated wireless power transmission device 10 for wireless power transmission to other portable wireless devices 20 such as another smartphone or wearable device And is configured to provide wireless power.

The portable radio apparatus 100 is configured to detect the movement or motion of the portable radio apparatus 100 to determine the radio power reception timing and the radio power transmission timing to efficiently perform the radio power reception and the radio power transmission.

Here, the portable wireless device 100 determines the optimal timing for maximizing the transmission / reception efficiency at the time of transmission / reception of the wireless power because it minimizes the waste of the standby power and performs the wireless charging operation.

The portable wireless device 100 is particularly useful for wirelessly charging the portable wireless device 20, that is, the wearable device. The portable wireless device 100 is characterized in that the wearable device is constantly worn, So as to determine the wireless power transmission timing and the wireless power reception timing sufficiently.

In other words, the portable wireless device 100, that is, a typical smart phone, receives the wireless power itself to charge the battery 110, and the power charged in the battery 110 is optimized for the wearable device connected to the smartphone To be wirelessly charged. Such a configuration has the advantage that unnecessary increase in power consumption during wireless charging operation between smartphone and wearable device can be reduced and consumption of standby power can be reduced.

Hereinafter, the detailed configuration will be described.

Battery 110 may be configured to charge or discharge power as a charge reservoir. Charging and discharging may be repeatedly performed, and may be composed of a lithium ion battery.

The wireless power resonator 120 may be configured to wirelessly transmit and receive wireless power or a beacon signal. Here, the wireless power may be configured to transmit and receive by a magnetic induction method or a magnetic resonance method.

The wireless power receiving module 130 may be configured to receive the power wirelessly received from the wireless power resonator 120 to charge the battery 110. [ At this time, the power wirelessly received through the wireless power resonator 120 may be received from the wireless power transmission device 10. [ The wireless power transmission device 10 may be a separate dedicated transmission device for wireless charging.

The wireless power transmission module 140 is connected to the battery 110 and may be configured to transmit and discharge the power charged in the battery 110. [ At this time, the wireless power transmission module 140 may be configured to wirelessly transmit or wirelessly transmit power through the wireless power resonator 120.

Meanwhile, the wireless power transmission module 140 may be configured to wirelessly transmit a beacon signal through the wireless power resonator 120 to search for another portable wireless device 20. [ Here, the other portable wireless device 20 is preferably a wearable device such as Google glass and i-watch, or may be another smartphone.

The wireless power transmission / reception switching module 150 may be configured as a switch circuit.

The wireless power transmission / reception switching module 150 may be configured to switch to either a wireless transmission state or a wireless reception state. That is, the wireless power transmission / reception switching module 150 may transmit the beacon signal through the wireless power resonator 120 or wirelessly transmit the beacon signal through the wireless power resonator 120, Or to switch to a wireless receiving state in which the wireless power received by the wireless power resonator 120 is charged to the battery 110 via the wireless power receiving module 130. [

The gyro sensor 160 may be configured to detect movement of the portable wireless device 100. It may be configured to detect the acceleration according to the movement of the portable wireless device 100 and to detect the movement thereof.

The control module 170 may be configured to determine and determine the wireless power transmission timing and the wireless power reception timing appropriately. That is, the control module 170 may be configured to determine the timing of switching between the wireless reception state and the wireless transmission state.

The control module 170 may be configured to set the wireless reception state to a wireless reception state at a normal time and to receive power from the wireless power transmission apparatus 10 to charge the battery 110. [

However, if the portable wireless device 100 is moved a lot, an operation error may occur even in wireless power charging. Therefore, the portable wireless device 100 can be configured to stop wireless power reception or wireless power transmission while it is still moving and to perform no operation.

On the other hand, if the motion is detected in the wireless receiving state and the motion thereof is stabilized, for example, if the acceleration is not detected for 100 ms to 3000 ms after the acceleration according to the motion is detected, And to transmit the beacon signal transmitted by the wireless power resonator 120 via the wireless power resonator 120. [

Here, when another portable wireless device 20 is found, the control module 170 may be configured to control the wireless power transmission / reception switching module 150 to switch to the wireless transmission state.

If no other portable wireless device 20 is found by the beacon signal, the control module 170 controls the wireless power transmission module 140 to transmit the beacon signal by increasing the transmission period of the beacon signal within a predetermined range ≪ / RTI > This is to reduce the power consumption by intermittently transmitting the beacon signal because the power consumption continuously increases when the period of the beacon signal is short. At this time, if the other portable wireless device 20 is not charged for a predetermined time, the control module 170 may be configured to terminate the transmission of the beacon signal and switch to the wireless reception state.

The control module 170 may be configured to control the wireless power transmission module 140 to wirelessly charge other portable wireless devices 20. That is, the portable radio device 100 can wirelessly supply the power of the portable radio device 100 to other wearable devices in the vicinity.

Then, when the movement of the portable wireless device 100 is detected in the wireless transmission state and the movement is stabilized, the wireless power transmission / reception switching module 150 may be controlled to switch to the wireless reception state. Specifically, if the acceleration is not detected for 100 ms to 3000 ms after the acceleration due to the motion is detected even in the wireless transmission state, the control module 170 controls the wireless power transmission / reception switching module 150 to switch to the wireless reception state Lt; / RTI >

In this manner, the wireless transmission state and the wireless reception state may be switched between the detection of the movement of the portable radio apparatus 100 and the stabilization of the position of the portable radio apparatus 100, instead of the detection and stabilization of the movement of the portable radio apparatus 100.

For example, when the control module 170 detects and stabilizes the front surface (display) of the portable wireless device 100 by being positioned by the gyro sensor 160 in the upward direction, for example, And if the acceleration is not detected for 100 ms to 3000 ms after the gyro sensor 160 detects the acceleration, it is detected that the back surface of the portable wireless device 100 is positioned upward by the gyro sensor 160, May be configured to control the wireless power transmission module 140 to transmit a beacon signal to search for another portable wireless device 20 if no acceleration is detected for 100 ms to 3000 ms after the acceleration according to the wireless network is detected. When another portable wireless device 20 is found, the control module 170 may be configured to control the wireless power transmission / reception switching module 150 to switch to the wireless transmission state.

If another portable wireless device 20 is not searched by the beacon signal, the transmission period of the beacon signal is increased and the other portable wireless device 20 is searched. If not, the beacon signal transmission is terminated, . ≪ / RTI >

On the other hand, the control module 170 can be configured to stop the wireless transmission of power when the gyro sensor 160 detects that the movement continues for a predetermined time or longer in the wireless transmission state. And to prevent an error from occurring in the wireless transmission of electric power by the movement. The control module 170 may be configured to control the wireless power transmission / reception switching module 150 to switch to the wireless reception state.

On the other hand, the control module 170 may preset a threshold of power to be wirelessly transmitted when wirelessly transmitting power. The control module 170 may be configured to control the wireless power transmission module 140 to terminate the power transmission when the power transmitted by the wireless power transmission module 140 reaches a preset wireless transmission threshold.

This is because if all the power is transmitted wirelessly, the portable wireless device 100, that is, the power available for the smartphone, may become insufficient. This threshold value may be configured to be variably determined according to the amount of charge remaining in the battery 110 of the smartphone. For example, it may be configured to wirelessly transmit until the remaining amount of charge reaches 30%, and may be configured to block switching to the wireless transmission state if the remaining amount of charge is not 30%.

FIG. 2 is a flowchart of a charging method of a portable wireless device having a wireless charging function using motion detection according to the first embodiment of the present invention.

Referring to FIG. 2, the wireless power transmission / reception switching module 150 sets the portable wireless device 100 to a wireless reception state under the control of the control module 170 (S110).

Next, the wireless power receiving module 130 receives the wirelessly received power through the wireless power resonator 120 and charges the battery 110 of the portable wireless device 100 (S120).

Next, the acceleration of the portable wireless device 100 is detected in real time by the gyro sensor 160 (S130).

Next, another portable radio 20 is searched by the detection value of the gyro sensor 160 (S140). Specifically, if acceleration is not detected for 100 ms to 3000 ms after the acceleration is detected by the gyro sensor 160 (S141), the control module 170 causes the wireless power transmission module 140 to transmit a beacon signal And searches for another portable wireless device 20 (S142).

Next, the control module 170 switches to the wireless transmission state or the wireless reception state according to the search result of the beacon signal (S150).

Specifically, when the portable wireless device 20 is searched for (S151), the wireless power transmission / reception switching module 150 transmits the portable wireless device 100 to the wireless transmission state (S152).

On the other hand, if the search result is not retrieved, control is performed so that the beacon signal is transmitted by increasing the transmission period of the beacon signal within a predetermined range in order to minimize power loss (S153), and the other portable wireless device 20 If it is not detected, it can be configured to switch to the wireless reception state (S110).

Next, the process of the radio transmission state is performed (S160).

Here, the wireless power transmission module 140 emits the power of the battery 110 of the portable wireless device and wirelessly transmits the wireless power through the wireless power resonator 120 (S161). If the detection of movement by the gyro sensor 160 in the wireless transmission state continues for a predetermined time or longer (S162), in order to prevent an error from occurring in the wireless transmission of electric power, Transmission is stopped and the wireless power transmission / reception switching module 150 is controlled to switch to the wireless reception state (S110). When the amount of radio transmission reaches a predetermined radio transmission threshold value in the radio transmission state (S163), the radio power transmission module 140 stops power transmission (S164).

Referring to FIG. 3, the wireless power transmission / reception switching module 150 sets the portable wireless device 100 to a wireless receiving state under the control of the control module 170 (S210).

Next, the wireless power receiving module 130 receives power wirelessly received through the wireless power resonator 120 and charges the battery 110 of the portable wireless device 100 (S220).

Next, the gyro sensor 160 detects the attitude of the portable radio device 100 in real time (S230).

Next, the wireless receiving state is maintained or the beacon signal is searched according to the attitude of the portable wireless device 100 (S240).

Here, if acceleration is not detected for 100 ms to 3000 ms after the front face (display) of the portable wireless device 100 is detected by the gyro sensor 160 to be oriented upward (S241), the control module 170 The portable wireless device 100 is held in a wireless reception state at step S210 and the back side of the portable wireless device 100 is detected by the gyro sensor 160 as lying face up, The control module 170 controls the wireless power transmission module 140 to transmit a beacon signal to search for another portable wireless device 20 (S243). At this time, it is determined whether the control module 170 is searched for another portable wireless device 20 (S244). If it is not detected as a result of the determination, the transmission period of the beacon signal is increased within a predetermined range to minimize the power loss, (S245). If the other portable wireless device 20 is not searched for a predetermined time (S246), the wireless communication device 100 switches to the wireless receiving state (S210).

If another portable wireless device 20 is found as a result of the search, the wireless power transmission / reception switching module 150 switches the portable wireless device 100 to the wireless transmission state under the control of the control module 170 (S250) .

Next, the process of the radio transmission state is performed (S260).
