[0020] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0021] To better understand the technical solutions of this application, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments.

It should be understood that although the steps in the flowcharts of the embodiments of this application are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders.

[0023] Most current charging adapters have a display screen to show users information such as the charging status of their devices or the charging adapter itself. However, due to the small size of the charging adapter, the screen size is also limited, making it difficult to display a lot of information. Therefore, multiple display interfaces are often provided, which users switch between by touching the screen. However, this switching method is difficult for users due to the small screen size, and it's also difficult to operate smoothly when the user's fingers are wet.

[0024] Therefore, this application proposes a charging head with gesture sensing function. It should be noted that the charging head also has a rectifier module and a charging module for converting the input AC mains voltage into a charging voltage. The rectifier module is used to rectify the input AC voltage, and the rectified voltage is adjusted by the charging module and then output to the device to be charged.

[0025] refer to Figure 1 In one embodiment of this application, the charging head with gesture sensing function includes: A charging head body, on which a display component 10 is provided; Control circuit 20, which is disposed in the charging head body and electrically connected to the display component 10; A gesture sensing component 30 is disposed on the charging head body and is electrically connected to the control circuit 20. The gesture sensing component 30 is used to detect the user's gesture actions and output corresponding gesture sensing signals to the control circuit 20. The control circuit 20 is used to control the display component 10 to display the corresponding image based on the gesture sensing signal.

[0026] In this embodiment, the display component 10 can be implemented using a TFT display component 10, an LCD display component 10, an LED display component 10, etc. The control circuit 20 can control the display component 10 to display a preset corresponding screen, such as information representing the current charging status, a screen representing time information, a screen representing static operation, etc.

[0028] The controller 21 can be implemented using an MCU, DSP (Digital Signal Processor), FPGA, or similar technology. The storage module 22 is electrically connected to the controller 21, allowing the controller 21 to write or read data from the storage module 22 via communication. The storage module 22 can be implemented using a memory chip and its peripheral circuitry.

[0029] Furthermore, in another embodiment, to facilitate data interaction between the control circuit 20 and an external terminal, in one embodiment, refer to... Figure 2 and Figure 3 and Figure 7 The charging head with gesture sensing function further includes: a debugging interface 23, which is disposed on the charging head body and electrically connected to the controller 21; the debugging interface 23 is used to connect to an external terminal; the controller 21 is used to communicate with the external terminal via the debugging interface 23. In this embodiment, the debugging interface 23 can be a USB interface, a Lightning interface, a Type-C interface, etc., and the debugging interface 23 is electrically connected to the controller 21 so that the controller 21 can establish data interconnection with the connected external terminal through the debugging interface 23. For example, see reference... Figure 2 and Figure 3 and Figure 7 As shown, the three pins on the debug interface 23 are electrically connected to the data pins (including NRST1, SWCLK, and SWDIO) on the controller 21. When an external terminal is connected, the controller 21 establishes a data interconnection with the external terminal through the data pins and the three pins on the debug interface 23.

[0030] Optionally, in one embodiment, the gesture sensing component 30 can be implemented using a camera component and an image recognition module. The image recognition module is used to recognize the gesture image acquired by the camera component and output the corresponding gesture sensing signal to the control circuit 20.

[0031] Optionally, refer to Figure 2 and Figure 3 and Figure 7 In another embodiment, the gesture sensing component 30 includes: An infrared gesture sensor module is disposed on the charging head body; An interface circuit 31 is disposed within the charging head body and is electrically connected to the control circuit 20. The interface circuit 31 is used to connect to the infrared gesture sensor module. The infrared gesture sensor module is used to detect the user's gesture actions and output corresponding gesture sensing signals to the control circuit 20 via the interface circuit 31.

[0032] In this embodiment, the interface circuit 31 includes: a first interface for the charging head, a first pull-up resistor, and a second pull-up resistor; the first interface has a power supply terminal, a data terminal, a clock signal terminal, and an interrupt signal terminal for outputting a first operating voltage, and the first interface is used to connect to an infrared gesture sensor module; the data terminal, clock signal terminal, and interrupt signal terminal of the first interface are electrically connected to the control circuit 20; the first end of the first pull-up resistor and the first end of the second pull-up resistor are respectively connected to the first power supply terminal, the second end of the first pull-up resistor is connected to the data terminal, and the second end of the second pull-up resistor is connected to the clock signal terminal. When the infrared gesture sensor module is connected to the first interface, the power supply terminal of the first interface is electrically connected to the power supply terminal of the infrared gesture sensor module, the data terminal of the first interface is electrically connected to the data terminal of the infrared gesture sensor module, the clock signal terminal of the first interface is electrically connected to the clock signal terminal of the infrared gesture sensor module, and the interrupt signal terminal of the first interface is electrically connected to the interrupt signal terminal of the infrared gesture sensor module. The infrared gesture sensor module can be implemented using a corresponding device module, such as an infrared gesture sensing module. The first interface can be implemented using a standard interface, such as a USB interface, a Lightning interface, a Type-C interface, etc., or it can be implemented using an inter-board connector. The infrared gesture sensor module can receive the required first operating voltage through the first interface, for example, as shown in the reference... Figure 2 and Figure 3 and Figure 7 , Figure 2The controller 21 in the control circuit receives the first voltage output from the first power supply terminal and outputs a first operating voltage corresponding to the infrared gesture sensor module, wherein the first operating voltage is less than or equal to the first voltage. The infrared gesture sensor module can also output the detected gesture movements via the first interface to the controller 21 in the control circuit 20. The controller 21 in the control circuit 20 can determine the user's gesture based on the gesture sensing signal and, according to the gesture movement-display control logic mapping table pre-stored by the developers, control the display component 10 to display the corresponding image. For example, the display component 10 can display multiple different images in a first order. When the control circuit 20 determines that the user's gesture is to the left based on the gesture sensing signal, it switches the current screen to the previous screen in the first order; when the gesture is to the right, it switches the current screen to the next screen in the first order.

[0033] Thus, through the above settings, in practical applications, users can control the images displayed on the display component 10 of the charging head through gestures, such as switching controls, without having to directly touch the display component 10. This application effectively improves the convenience for users to switch the content displayed on the screen of the charging head.

[0034] refer to Figure 2 and Figure 3 and Figure 7 and Figure 4 In one embodiment of this application, the display component 10 includes: A TFT display screen is mounted on the charging head body; The second interface 11 is disposed in the charging head body. The second interface 11 is electrically connected to the control circuit 20. The second interface 11 is used to connect to the TFT display screen. A first switching circuit 12 is disposed within the charging head body. The input terminal of the first switching circuit 12 is connected to a first power supply terminal, the output terminal of the first switching circuit 12 is connected to the power supply terminal of the TFT display screen, and the controlled terminal of the first switching circuit 12 is electrically connected to the control circuit 20. The power supply terminal of the display component 10 includes the input terminal of the first switching circuit 12. The control circuit 20 is used to output a display screen control signal via the second interface 11 to control the TFT display screen to display corresponding images, and is also used to control the first switching circuit 12 to turn on / off the path between the first power supply terminal and the power supply terminal of the TFT display screen.

[0035] In this embodiment, the second interface 11 can be implemented using a gold finger connector for connecting to the TFT display screen. This arrangement facilitates the assembly of the TFT display screen during the manufacturing of the charging head. The first switching circuit 12 can be implemented using a switching transistor, such as a MOSFET or IGBT, or a switching device such as a relay. For example, see Reference... Figure 3 In one embodiment shown, the first switching circuit 12 includes a first switching transistor, a third pull-up resistor, and an RC filter circuit. The input terminal of the first switching transistor and the first terminal of the third pull-up resistor are respectively connected to the first power supply terminal. The controlled terminal of the first switching transistor and the second terminal of the third pull-up resistor are respectively electrically connected to the control circuit 20. The output terminal of the first switching transistor is connected to the power supply terminal of the TFT display screen via the RC filter circuit. The controller 21 in the control circuit 20 can control the power-on and power-off of the TFT display screen by outputting corresponding control signals to the first switching transistor. Simultaneously, the controller 21 in the control circuit 20 can also output display screen control signals (including multiple control signals) through multiple pins in the second interface 11 to control the TFT display screen to display corresponding images.

[0036] refer to Figure 2 and Figure 3 and Figure 7 and Figure 5 In one embodiment of this application, the charging head with gesture sensing function further includes: A touch button is provided on the charging head body; A touch detection module 40 is disposed in the charging head body, and the touch detection module 40 is electrically connected to the control circuit 20 and the touch button respectively. The touch detection module 40 is used to output a corresponding trigger signal to the control circuit 20 when the touch button is triggered by the user. The control circuit 20 is used to control the display component 10 to display the corresponding image according to the trigger signal.

[0037] In this embodiment, the touch button can be implemented using a metal sheet disposed on the charging head body, and the touch detection module 40 can be a capacitive touch detection module 40 or a resistive touch detection module 40. For example, the touch detection module 40 is as follows: Figure 4 The image shows a capacitive touch detection module 40, which is electrically connected to the touch button. It can detect changes in the capacitance of the touch button to determine that the user has touched the touch button and output a corresponding trigger signal to the control circuit 20.

[0038] The control circuit 20 can control the display component 10 to display corresponding images based on the received trigger signal and the control logic of the display component 10 pre-stored by the developers. For example, each time the control circuit 20 receives a trigger signal, it will control the display interface to display the next image of the current screen in a predetermined order.

[0039] Thus, through the above settings, users can not only control the screen displayed by the display component 10 through gestures, but also control the screen displayed by the display component 10 by triggering the touch button on the charging head body, effectively meeting the user's needs for different screen control methods.

[0040] refer to Figure 6 and Figure 7 In one embodiment of this application, the charging head with gesture sensing function further includes: A step-down power supply module 50, the input terminal of which is used to connect to an external voltage, and the output terminal of which is connected to the power supply terminal of the control circuit 20 and the power supply terminal of the display component 10 via a first power supply terminal. The step-down power supply module 50 is used to step down the external voltage and output a first voltage through the first power supply terminal.

[0041] In this embodiment, the step-down power supply module 50 can be implemented using a step-down chip and corresponding peripheral circuitry, for example, refer to... Figure 5 The step-down chip and its peripheral circuit shown, or the step-down power supply module 50, can also be implemented using a step-down circuit formed by multiple switching transistors, resistors, capacitors and inductors.

[0042] The external voltage connected to the input terminal of the step-down power supply module 50 can be the voltage output by the rectifier module inside the charging head after rectifying the AC voltage connected to the charging head, or it can be the voltage output by other step-down power supply modules 50 inside the charging head after stepping down the DC voltage output by the rectifier module.

[0043] It is understandable that different circuit modules within the charging head require different operating voltages. Therefore, the step-down power supply module 50 can step down the external voltage and output a first voltage through the first power supply terminal to power the control circuit 20 and the display assembly. For example, refer to... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The external voltage VIN is 20V, and the first voltage VDD1 is 3.3V. The step-down power supply module 50 outputs the first voltage VDD1 to the power supply terminal of the controller 21, the input terminal of the first switching circuit 12, and the power supply terminal of the touch detection module 40 to provide the required operating voltage for the controller 21, the first switching circuit 12, and the touch detection module 40.

[0044] The above settings can meet the operating voltage requirements of different circuit modules within the charging head, effectively improving the charging head's compatibility with different circuit modules.
