Fig. 1 is a perspective view of a preferred embodiment of the power supply device of the present invention.

Fig. 2 is a layout view of an electronic circuit of a power supply device.

Figure 3 is a schematic diagram of charging of the power supply unit.

Fig. 4 is a view showing the state of use of information transmitted by the power supply device.

Referring to Figures 1 and 2, a specific configuration of a preferred embodiment of the power supply unit 10 is illustrated, with a circuit board 14 protected by a non-conducting housing 12.

The electronic circuit configuration of the circuit board 14 is shown in FIG. 2, in which a charging control circuit 22, a battery module 24 and a transformer circuit 26 are sequentially connected between a power input 20 and a power output 28. The charging control circuit 22 and the transformer circuit 26 are electrically connected to a microprocessor 30 to determine the voltage value of the power input 20 to the power output 28.

In this embodiment, the power input and output 20, 28 are Universal Serial Bus (USB) sockets. In some embodiments, the power input, output 20, 28 is a USB plug. Of course, the housing 12 does not obscure the interface of the USB plug or socket.

The microprocessor 30 communicates a message via a wired transmission 32 and a wireless transmission 34. The information is stored in a memory unit 40 electrically connected to the microprocessor 30, and is output to a portable device 50 according to the wired transmission 32 or the wireless transmission 34 (as shown in FIGS. 3 and 4).

Wired transmission 32, as referred to herein, generally refers to a power line 44 that conforms to the USB specification as shown in FIG.

Wireless transmission 34, referred to herein, generally refers to one of the Wi-Fi and Bluetooth wireless communication protocols.

The microprocessor 30 is electrically connected to a power display unit 36 and a charge indicating unit 38. In FIG. 1, the power indicator unit 36 is a row of indicator lights 18 that partially expose the housing 12. Assuming that the single indicator light 18 is bright, the power of the battery module 24 is insufficient; the entire row of indicator lights 18 is illuminated, indicating that the power of the battery module 24 is sufficient, and whether the power supply device 10 can perform the charging operation can be determined.

In this embodiment, the charging indicating unit is a single LED lamp 11. When the LED lamp 11 emits light, the brightness of the LED lamp 11 is seen from the translucent casing 12, indicating that the power supply device 10 is in use.

The battery module 24 is a plurality of batteries that supplement power, and the capacity specifications of each battery are divided into 2200 mAh, 2400 mAh, and 2600 mAh or more. In some embodiments, the battery module 24 is at least one polymer battery, such as a lithium polymer battery.

When the USB socket 16 is combined with the output end of a power line 42, the input end of the power line 42 can be inserted into a general socket in the room, and the general voltage is converted into a voltage required by the power supply device 12 through a transformer circuit (usually about 5V). ).

Of course, different specifications of the power cord 42 can be electrically connected to other portable devices 50, such as the USB socket of the desktop computer of Figure 4 (usually 4.2V). The battery module 24 can supplement the power after a period of time, and can perform charging operations on other portable devices 50, such as the wisdom of FIG. The smart phone 52, the notebook computer 58 of FIG. 4 or the iPad (not shown).

Taking the smart phone 52 of FIG. 3 as an example, an application 56 (App) is downloaded and installed, and the application 56 displays the related pattern on the screen 54 of the smart phone 52. When the pattern is clicked, the application 56 activates the microprocessor 30 (as shown in Figure 2) to determine the aging of the charge.

From the perspective of battery charging, the charge control circuit 22 performs a multi-stage charging operation in accordance with the voltage change of the battery. For example, when the voltage is <3V, the charging control circuit 22 trickle charges the battery according to the current of 100 mA to protect the battery after over-discharging. At a voltage > 3 V, the charge control circuit 22 charges the battery with a constant current of 1 A. When the voltage is approximately equal to 4.2V, the charge control circuit 22 converts to a constant voltage until the current drops to about 100 mA to stop the charging operation and relatively adjust the charging time or efficiency.

From the perspective of battery discharge, the battery module 24 has an average voltage of about 3.7V per battery, and is converted to 5V via the transformer circuit 26 of FIG. 2 to charge the portable device 50 such as the smart phone 52.

Next, see FIG. 4, through the setting of the application (App), the smart phone 52 operates the power supply device 10 to use the wired transmission mode to download the information of the notebook computer 58 via the power line 44, such as a document file, a drawing file, and a multimedia file. . The information stored in the memory unit of the power supply device 10 is output to the smart phone 52 or other portable device 50, such as a desktop computer, through the wireless transmission mode.

The desktop computer has a host 60 electrically connected to a display 62 and an input device 64, such as a keyboard 66 or a mouse 68. The host 60 stores the information of the notebook computer 58 in the wireless transmission mode, and the display device 62 operates the display device 62 to display the content of the information. Of course, the host 60 stores other information, and can also be uploaded to the Internet or a cloud computing unit (not shown), or downloaded to the power supply device 10, the smart phone 52, or the note computer 58. In other words, the power supply Information transmitted between the memory unit of device 10 and portable device 50 can be stored.
