It should be understood that the specific examples described herein are only used to explain the present application, and are not used to limit the present application.

[0034] Please refer to FIG. 1 and FIG. 2, the present application provides a charger 1, which includes a shell 11, a knob 12, a knob detection structure 2, a main control board 131, a display 134 and a charging control unit 132.

[0035] The shell 11 is used for protecting the components arranged in the shell 11. The shell 11 can be made of plastic or metal. Specifically, the shell 11 can be made of plastic, so that the shell 11 is insulated, thereby reducing the risk of electric shock for the user. In addition, the plastic material is light in weight, so that the shell 11 is light in weight, thereby reducing the overall weight of the charger 1, so as to facilitate the user to carry and use the charger 1. Specifically, the shell 11 can be integrally injection molded, so that the shell 11 has high structural strength, thereby reducing the damage of the shell 11 and the other components in the shell 11, reducing the probability of damage of the other components, thereby prolonging the service life of the charger 1. The shell 11 further has a power interface (not shown in the figure) for connecting to the power supply.

[0036] The knob 12 is rotatably arranged on the shell 11, so as to control the charger 1 by operating the knob 12.

Specifically, the knob detection structure 2 can include at least one of an electrically conductive mechanical structure, a magnetic detection structure, a light detection structure, a pressure detection structure, and a dial detection component, so that the knob detection structure 2 can obtain at least one of the rotation parameter, the pressing parameter and the dial parameter of the knob 12, thereby enabling the main control board 131 to control the charging control unit 132 according to the corresponding parameter. Specifically, the knob detection structure 2 is used for detecting at least the rotation parameter of the knob 12. Specifically, the rotation parameter can include the rotation angle and / or the rotation direction.

[0038] The main control board 131 is arranged in the shell 11 and electrically connected with the knob detection structure 2 and the battery.

The detection board is used for detecting at least one of the rotation parameter, the pressing parameter and the dial parameter of the knob 12 and sending the corresponding parameter to the main control board 131.

[0039] The display 134 is arranged on the shell 11 and exposed to the shell 11 and electrically connected with the main control board 131.

[0040] The charging control unit 132 is electrically connected with the main control board 131. Illustratively, the charging control unit 132 comprises a charging circuit 141 and a plurality of charging ports 1321, the charging ports 1321 are arranged on the shell 11 and exposed to the shell 11, and the plurality of charging ports 1321 are electrically connected with the main control board 131. The user can operate the knob 12 to make the main control board 131 acquire at least one of the rotation parameter, the pressing parameter and the dialing parameter of the knob 12 via the knob detection structure 2, so that the main control board 131 can control the display 134 to switch the charging information of different charging ports 1321 according to the corresponding parameter.

[0042] It can be understood that the charging circuit 141 can be etched on a charging circuit board to improve the production efficiency of the charging circuit 141, and the charging circuit board can be electrically connected with the main control board 131 provided with the main control chip 32. The charging circuit 141 can be etched on the main control board 131. This is not specifically limited in the embodiments of the present application.

[0043] It can be understood that the charging circuit 141 comprises a rectifier module 1411, a transformer module 1412 and a protocol chip 1413 (please refer to FIG. 17).

The filter circuit is used to filter the pulsating direct current output by the rectifier circuit to make the waveform of the output direct current smooth. The voltage stabilizing circuit is used to keep the output voltage constant. In the embodiments of the present application, the specific form of the rectifier module 1411 is not limited.

[0045] The transformer module 1412 is configured to boost or step down the direct current output by the rectifier module 1411 and supply power to the charging port, so that the charging port outputs a corresponding voltage. Specifically, the protocol chip 1413 can be connected with the charging port and the transformer module 1412. After the external device is connected with the corresponding charging port 1321, the protocol chip 1413 can interact with the external device through the charging port 1321, and the content of the information interaction includes but is not limited to the remaining power of the external device and the rated charging power of the external device. Then, the protocol chip 1413 can output the power parameter information corresponding to the external device to the transformer module 1412, so that the transformer module 1412 can output the charging power required by the external device, thereby realizing the matching of the output power of the charging circuit 141 and the external device.

In other embodiments, the fast charging protocol supported by the protocol chip 1413 can also include other types, which can be selected according to the application range of the product.

[0047] It can be understood that the charger 1 can also be communicatively connected with the external device having the display 134, so that the main control board 131 can transmit the display information to the external device, so that the display 134 of the external device displays the picture, and the display 134 of the external device can also be touched to control the charger 1. The communication connection mode includes at least one of wired communication, WLAN (Wireless Local Area Network), RFID (Radio Frequency Identification), NFC (Near Field Communication), ZigBee, Bluetooth and infrared.

[0049] It can be understood that the charger 1 involved in the present application is mainly suitable for powering mobile phones, earphones, tablet computers, smart watches and other small external devices, for example, the charger 1 can be a desktop charger; and it is not suitable for powering large devices such as electric vehicles and electric cars, for example, the charger 1 cannot be a charging pile.

The rotation detection chip is electrically connected with the main control board 131 to detect the rotation angle and rotation direction of the knob 12, in combination with the conduction signal of the second electrical connection member 222 and the first electrical connection member 221, so that the main control board 131 obtains the rotation parameter of the knob 12. For example, the material of the conductive member 211 can be metal, such as copper and gold.

[0054] It can be understood that, in order to prevent the first electrical connection member 221 and the second electrical connection member 222 from being conductive with the knob 12, the knob 12 can be made of an insulating material, such as plastic.

[0055] Please refer to FIGS. 3 and 4. In the embodiment of the present application, the conductive member 211 and the knob 12 can also be connected by an insulating structure.

[0091] The step S310 controls the display 134 to switch to display the charging information of different charging ports 1321 according to the rotation parameter; the charging information comprises at least one of charging power, charging voltage and charging current.

[0092] In the embodiment of the present application, when the charger 1 is in the display mode of the charging information of the charging port 1321, the knob 12 is rotated, the knob 12 can drive the driven member 21 to rotate, so that the main control board 131 can obtain the rotation parameter of the knob 12 via the rotation detection assembly 22, and then the main control board 131 can control the display 134 to switch the display of the charging information of the charging port 1321 according to the rotation parameter.
