To save space. Based on this design, since the input module and the near field communication antenna overlap each other, the functions of the input operation and the near field communication are not simultaneously performed to avoid mutual interference between the two operations. Therefore, when any of the foregoing functions are performed, the device continues to supply power to both the input module and the near field communication module, which will cause the idle module to consume power resources and reduce the available mobility of the mobile device. The time of use.

1 is a system block diagram of a mobile device 1 of the present invention.

As shown in FIG. 1 , the mobile device 1 of the present invention includes a main body 10 , an input module 20 , a near field communication module 30 , and a power module 40 . The input module 20 , the near field communication module 30 , and the power module 40 . Both are coupled to the body 10. The main body 10 includes a system module 11 which can be at least one of a hard body, a soft body and a firmware, or a combination thereof, such as a central processing unit, a storage device, an operating system, and related control elements or circuits.

The input module 20 is electrically connected to the system module 11. The input module 20 can be a button group, a keyboard device, a touch pad or a touch panel, etc., for the user to input commands to communicate with the system module 11 or directly control the corresponding components.

The near field communication module 30 incorporates the input module 20. The near field communication module 30 includes a processing unit 31 and an antenna structure 32. The processing unit 31 is electrically connected to the antenna structure 32, and the antenna structure 32 is stacked on the input module 20. The processing unit 31 is in the form of a chip, and is internally provided with a control circuit for processing the near field communication signal and storing related data, and is electrically connected to the system module 20.

Please refer to FIG. 2, which is a flow chart of a power saving method of the mobile device of the present invention. It should be noted that although the electronic device 1 shown in FIG. 1 is taken as an example to illustrate the power saving method of the mobile device of the present invention, the present invention is not limited to the mobile device 1 and any other similar structure action. The device can also be adapted to the method of the invention. As shown in FIG. 2, the power saving method of the mobile device of the present invention includes steps S1 to S5. The various steps of the method are described in detail below.

Step S1: After the mobile device 1 is powered on, the power is supplied to the input module 20 and the near field communication module 30.

When the user activates the mobile device 1 of the present invention to turn it on (for example, presses the power of the mobile device 1), the power module 40 supplies power to the system module 11 to enter the booting process, and starts to supply power to the input module 20 and the near field. The communication module 30 provides corresponding functions such as command input operation and near field communication.

Step S2: It is judged whether the input module 20 is in a use state.

After the device is powered on, it is necessary to determine whether the input module 20 is in use or not to perform the corresponding steps. In an embodiment of the present invention, the processing unit 31 of the near field communication module 30 can directly receive the input control signal from the input module 20, or can detect that the user performs the input module 20 by using the system module 11. The input operation determines whether the input module 20 is in use. If it is determined that the input module 20 is in the use state, the process proceeds to step S3; if it is determined that the input module 20 is not currently used, the original power supply state is maintained.

Step S3: If the input module 20 is in use, the near field communication module 30 is switched to the power saving mode.

When the foregoing step S2 determines that the input module 20 is in the use state, it indicates that the user is performing an input operation by using the input module 20, that is, the near field communication module 30 does not need to be used. Therefore, the processing unit 31 can directly control the power control unit 311 to enter the power saving mode according to the input control signal of the input module 20 or the control signal of the system module 11 to reduce the power consumption of the near field communication module 30. In an embodiment of the present invention, the input module 20 or the system module 11 can also send the control signal to the power module 40, and the power module 40 switches the difference to the processing unit 31. The power supply state causes the power control unit 311 to switch to the power saving mode.

Step S4: When the near field communication module 30 enters the power saving mode, it is determined whether the input module 20 is away from the use state.

When the near field communication module 30 enters the power saving mode, the processing unit 31 of the near field communication module 30 continues to determine whether the input control signal from the input module 20 has been interrupted, or is detected by the system module 11 It is tested whether the user interrupts the input operation performed on the input module 20 to determine whether the input module 20 has left the use state. If it is determined that the input module 20 has left the use state, the process proceeds to step S5; if it is determined that the input module 20 remains in the use state, the near field communication module 30 remains in the power saving mode.

Step S5: If the input module 20 has left the use state, the near field communication module 30 is switched to leave the power saving mode.

When the foregoing step S4 determines that the input module 20 has left the use state, it indicates that the user has stopped or interrupted the input operation to the input module 20. At this time, the near field communication module 30 may have a use requirement. Therefore, the processing unit 31 directly determines that the input control module 20 does not provide the input control signal or the system module 11 does not provide the control signal, that is, the power supply control unit 311 is switched to leave the power saving mode, and returns to the state of general execution. In an embodiment of the present invention, after the power module 40 determines that the input module 20 or the system module 11 no longer sends the relevant control signal, the power supply module 40 switches the full power supply state of the processing unit 31, so that the near field communication module 30 Can be separated from the power saving mode.

In an embodiment of the present invention, in order to prevent the user from repeatedly performing the input operation in a short time, the number of times the near field communication module 30 enters or leaves the power saving mode is too frequent, and the mobile device 1 of the present invention saves power. The method further includes steps S6 and S7.

Step S6 is further performed after step S4: determining whether the input module 20 is in the use state again within the set time.

In an embodiment of the mobile device 1 of the present invention, the timing unit 50 is further included. When the input module 20 leaves the use state, the timing unit 50 calculates the elapsed time after the input module 20 leaves the use state to determine Whether the input module 20 receives the user's input operation again within the set time and enters the use state. The timing unit 50 can perform time detection in conjunction with the system module 11 or independently input control signals of the input module 20 for calculating the interval between two input operations. Thereby, the system module 11 or the processing unit 31 determines whether the input module 20 is in the use state again within the set time. The preset time may be set by the system or set by the user. For example, the set time may be between 5 seconds and 10 seconds, but the invention is not limited thereto. If it is determined that the input module 20 does not receive another input operation within the set time, the process proceeds to step S5; if it is determined that the input module 20 is in the use state again within the set time, it indicates that the user still needs to perform an input operation using the input module 20. Therefore, the near field communication module 30 continues to remain in the power saving mode.

When the foregoing step S6 determines that the input module 20 is not in use again within the set time, it indicates that the user does not need to use the input module 20 at least temporarily. Therefore, the processing unit 31 can instruct the power control unit 311 to switch away from the power saving mode according to the foregoing step S5, and return to the general execution. After the power module 40 determines that the input module 20 or the system module 11 no longer sends the relevant control signal, the full power supply state of the processing unit 31 is switched, so that the near field communication module 30 can be disconnected from the power saving mode. .

Please refer to FIG. 3, which is a flow chart of another embodiment of the power saving method of the mobile device 1 of the present invention. As shown in FIG. 3, the power saving method of the mobile device 1 of the present invention further includes steps S7 to S9. The various steps added in the method will be described in detail below by taking the electronic device 1 shown in FIG. 1 as an example.

Step S7 is further performed after step S1: determining whether the near field communication module 30 is performing the near field communication function.

In the state that the power module 40 normally supplies power to the input module 20 and the near field communication module 30, the system module 11 can detect the near field communication module in addition to detecting whether the input module 20 is in use. The function execution state of 30 is to determine whether the near field communication module 30 is performing near field communication with an external device in order to perform the corresponding steps. In an embodiment of the present invention, the system module 11 detects whether the near field communication module 30 generates the relevant signal of the incoming communication; if the system module 11 detects that the near field communication module 30 is performing the near field If the communication function is continued, the step S9 is continued; if it is determined that the near field communication module 30 is not currently used, the original power supply state is maintained.

Step S8: If the near field communication module 30 is performing the near field communication function, the power supply to at least a portion of the input module 20 is cut off.

When the foregoing step S7 determines that the near field communication module 30 is performing the near field communication function, it indicates that the user is using the near field communication module 30 to perform near field communication data transmission with the external device, and it can be inferred that the current input module 20 should be No need to be used. Therefore, the system module 11 can command the power module 40 Power is supplied to at least a portion of the input module 20 to reduce excess power consumption of the input module 20.

In the design of the mobile device 1 of the present invention, the antenna structure 32 of the near field communication module 30 is superposed on the input module 20, and the antenna structure 32 surrounds at least a portion of the input module 20; The area of the system varies with different mobile devices 1 or design. Therefore, the system module 11 can command the power module 40 to cut off power supply to at least a portion of the input module 20 according to different designs. Hereinafter, the notebook computer will be described as an embodiment of the mobile device 1, but the present invention is not limited thereto.

Please refer to Figure 4(a) to Figure 4(c) together. 4(a) is a schematic view showing a first embodiment of the mobile device structure 32 incorporating the antenna structure 32 in the input module 20; and FIG. 4(b) is a mobile device structure 3a of the present invention incorporating the antenna structure 32a into the input module. FIG. 4(c) is a schematic diagram showing a third embodiment of the mobile device 32b incorporating the antenna structure 32b in the input module 20b according to the mobile device 1b of the present invention.

As shown in FIG. 1 and FIG. 4( a ), it is assumed that the mobile device 1 of the present invention has an input module 20 that is a touchpad and an antenna structure 32 that is disposed around the entire touch panel. In this embodiment, the antenna structure 32 surrounds nearly all of the area of the touchpad. When the mobile device 1 of the present invention performs the near field communication function by the antenna structure 32 of the near field communication module 30, the touch panel is completely unusable; therefore, the system module 11 can command the power module 40 to cut off the entire input mode. Group 20 power supply.

As shown in FIG. 4(b), this embodiment is a variation of the foregoing embodiment. It is assumed that the input module 20a is still a touch panel, and the antenna structure 32a occupies about half of the entire touch panel. In this embodiment, the antenna junction The structure 32a surrounds a portion of the touch panel. When the mobile device 1a of the present invention performs the near field communication function by the antenna structure 32a of the near field communication module 30a, the other half of the touch panel not surrounded by the antenna structure 32a can still be used; therefore, the system module 11 The power module 40 can be commanded to cut only the power supply of the touchpad area provided with the antenna structure 32.

As shown in FIG. 4(c), it is assumed that in the mobile device 1b of the present invention, the input module 20b is a keyboard, the keyboard may include a main button area 21b and a numeric keypad 22b, and the antenna structure 32b is provided on the keyboard. Around the keypad 22b. In this embodiment, the antenna structure 32b encloses only a portion of the keyboard area. When the mobile device 1b of the present invention performs the near field communication function by the antenna structure 32b of the near field communication module 30b, the main button area 21b not surrounded by the antenna structure 32b can still be used; therefore, the system module 11 can The command power module 40 only cuts off the power supply of the numeric keypad 22b provided with the antenna structure 32b.

Step S9: After the near field communication module 30 finishes executing the near field communication function, power supply to at least a portion of the input module 20 is resumed.

When the foregoing step S8 determines that the near field communication module 30 has finished performing the near field communication function, the input module 20 may have a demand for use at this time. Therefore, the system module 11 can instruct the power module 40 to resume power supply to at least a portion of the input module 20, and return to the state of general execution.

According to the design of the present invention, when the user performs an input operation on the mobile device or performs a near field communication operation, the power supply state of the idle near field communication module or the input module can be adjusted correspondingly, thereby reducing the excess cost of the mobile device.
