[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] This utility model proposes a power bank with an LCD display screen 8, such as... Figures 1 to 7 As shown, a preferred embodiment of the power bank with an LCD display screen 8 of this utility model includes a housing, a PCB board, and a lithium battery 1. The PCB board and the lithium battery 1 are disposed inside the housing. The PCB board integrates a fast charging protocol charging and discharging management chip 2, a power module 3, a CC control chip 4, a DP conversion and image processing chip 5. The housing is provided with an LED indicator 6, a speaker 7, a USB-C1 interface and a USB-C2 interface. The LCD display screen 8 is disposed on the back of the housing.

[0040] The fast charging protocol charge / discharge management chip 2 is connected to the lithium battery 1, power module 3, CC control chip 4, LED indicator 6, and USB-C1 interface, respectively. The CC control chip 4 is also connected to the USB-C2 interface, DP conversion and image processing chip 5. The DP conversion and image processing chip 5 is also connected to the USB-C2 interface, speaker 7, and LCD display 8.

[0041] In this embodiment, the USB-C1 interface is used for power bank input or to power peripherals with USB-C interfaces.

[0042] The USB-C2 interface has a 24-pin fully functional data interface, through which the device's display source is input. It should be noted that the USB-C2 interface cannot be used as a charging port for this device; it can be used as a discharge port to provide power to connected devices, such as mobile phones, iPads, and other smart electronic devices.

[0043] The fast charging protocol charge / discharge management chip 2 is mainly used for the charging and discharging management of the lithium battery 1, full charge or low charge protection, measurement and indication of the charge / discharge point status or remaining power of the lithium battery 1, identification of the connection or disconnection of the charger or peripheral device, and fast charging protocol handshake or control. The fast charging protocol charge / discharge management chip 2 can be a charge / discharge management chip in the prior art, such as a chip from Injoinic.

[0044] The CC control chip 4 is mainly used for identifying device access or disconnection via the USB-C2 interface, powering accessed devices or performing protocol communication handshakes, and forwarding the DP Alt Mode protocol handshake of the DP conversion and image processing chip 5. The CC controller can be a chip from existing technology, such as a multi-CC controller from Ledray.

[0045] like Figure 2 As shown, the process steps of the CC control chip 4 are as follows:

[0046] Step 1; Standby mode, waiting for the USB-C device to connect;

[0047] Step 2: Negotiate with USB-C to supply power to the connected device;

[0048] Step S3: After the power handshake negotiation with the access device is completed, the forwarding DP conversion and image processing chip 5 forward CC handshake are completed;

[0049] Step S4: Wait for the connected device to be unplugged, or for the battery to be found to be low on power; if the device is found to be unplugged, proceed to step 1, or if the battery is found to be low on power and the current state is battery powered, proceed to step 5; otherwise, remain in the waiting state.

[0050] Step 5: If the battery is low and the device is currently powered by the battery, negotiate with the connected device to switch to device power. After the device power function is successfully started, return to Step 4 and wait for the device to be unplugged.

[0051] The DP conversion and image processing chip 5 mainly has the following functions:

[0052] 1. Handshake with the USB-C2 interface access device to declare the permissible resolution or refresh rate of the LCD display screen 8;

[0053] 2. Analyze the audio and video streams sent by the USB-C2 interface access device via the DP interface;

[0054] 3. The extracted audio information is played back and output through speaker 7;

[0055] 4. The parsed image information is displayed on the LCD screen 8 via the MIPI / LVDS interface;

[0056] 5. Scaling or rotating the received image as needed before outputting and displaying it.

[0057] like Figure 3 As shown, the processing flow of the DP conversion and image processing chip 5 is as follows:

[0058] The DP conversion and image processing chip 5 detects whether a device is connected to the USB-C2 interface;

[0059] When the DP conversion and image processing chip 5 detects that a device is connected to the USB-C2 interface, the handshake between the two parties with the connected device is performed on the DiscretePort protocol version that is allowed by both parties, including resolution, refresh rate, and communication rate.

[0060] After a successful handshake, the received data stream is parsed. The audio portion of the data stream is sent to the speaker 7 to be converted into sound output, and the image portion is sent to the LCD display screen 8 for display after being appropriately scaled or rotated.

[0061] The LCD display screen 8 is mainly used to display the working status of the device, the image connection process between the device and the USB-C2 interface access device, and the image information after the video stream output by the USB-C2 interface access device is processed by the DP conversion and image processing chip 5. The LCD display screen 8 has a touch scanning function, and the scanning result is forwarded through the USB H ID protocol or BLE Bluetooth to control the device connected to the USB-C2 interface.

[0062] It is worth mentioning that, taking a mobile phone as an example, in this embodiment, the power bank with the LCD display 8 is connected to the mobile phone via a data cable, and the LCD display 8 can display the mobile phone's display interface, so that the user can clearly see the mobile phone screen when taking a selfie.

[0063] In this embodiment, the LED indicator 6 can be used to indicate the power level of the power bank with LCD display 8. For example, one LED indicator 6 lit indicates that the power bank with LCD display 8 has 25% remaining power, two LED indicator 6 lit indicates that the power bank with LCD display 8 has 50% remaining power, three LED indicator 6 lit indicates that the power bank with LCD display 8 has 75% remaining power, and four LED indicator 6 lit indicates that the power bank with LCD display 8 is fully charged.

[0064] Furthermore, in this embodiment, the power bank with LCD display 8 also includes a BLE Bluetooth chip 9, which is used to forward the touch information and status of the LCD display 8 and to control the application of the USB-C2 interface access device via Bluetooth.

[0065] Furthermore, in this embodiment, the power bank with LCD display 8 also includes a USB H ID protocol module 10. The USB H ID protocol module 10 is used to forward the touch information and status of the LCD display 810, and realizes the application control of the USB-C 2 access device by forwarding the touch information through the USB 2.0 H ID protocol.

[0066] Furthermore, in this embodiment, a bracket 11 is folded and provided on the lower front of the housing.

[0067] like Figure 4 and Figure 5 As shown, in one embodiment, the bracket 11 is elliptical and is folded at an angle to the lower front of the housing.

[0068] like Figure 6 and Figure 7 As shown, in another embodiment, the bracket 11 is rectangular and is folded laterally and disposed on the lower front of the housing.

[0069] This embodiment further enriches the functionality of the power bank with LCD display 8 by folding the bracket 11 at the lower front of the housing, allowing it to be used as a mobile phone stand 11 when needed.

[0070] Furthermore, in this embodiment, a first nut hole 12 is provided at the bottom of the housing; a second nut hole 13 is provided on one side of the housing.

[0071] In this embodiment, the first nut hole 12 and the second nut hole 13 are used to connect the selfie stick.

[0072] Furthermore, in this embodiment, a ring magnet is also provided inside the housing, which enables wireless charging while simultaneously attracting the mobile phone.
