[0027] In the embodiment, as shown in Figure 1As shown, it relates to a surface-skin replaceable power bank, including a power supply base 1 and a panel 2. The power supply base 1 integrates an energy storage battery 11, a charge-discharge interface 12 and a power button 13. The energy storage battery 11 provides power support for the power bank. The charge-discharge interface 12 is used to connect external devices for charging or discharging. The power button 13 is used to control the on-off state of the power bank. The energy storage battery 11 is electrically connected to the charge-discharge interface 12, the power button 13 and the control circuit board 21 built-in the panel 2 through internal circuits, ensuring the normal operation of the whole system. The panel 2 is provided with at least one pattern display area 22, which can display different patterns according to user needs. The control circuit board 21 built-in the panel 2 is used to control the pattern switching of the pattern display area 22. The user can trigger the pattern switching function by long pressing the power button 13 or other preset operations. After receiving the signal, the control circuit board 21 drives the pattern display area 22 to switch to the next preset pattern. The panel 2 is detachably attached to the surface of the power supply base 1. The user can replace the panel 2 with different patterns according to personal preferences or use scenarios.

[0028] In this embodiment, the power supply base 1 adopts a rectangular design, and is built-in with an energy storage battery 11. The surface is provided with a charge-discharge interface 12 and a power button 13. The panel 2 is built-in with a control circuit board 21 and an electronic ink display screen as a pattern display area 22. The control circuit board 21 is connected to the power supply base 1 through wires to realize the pattern switching function. The charge-discharge interface 12 can be a USB-C charging interface.

[0029] The pattern display area 22 is an electronic ink display screen or an LED dot matrix module. The electronic ink display screen is suitable for displaying static patterns. In another embodiment, the pattern display area 22 adopts an LED dot matrix module to support dynamic pattern display. Through the electronic ink display screen or the LED dot matrix module, flexible replacement of the appearance pattern is realized, and diversified display effects are also provided.

[0030] In this embodiment, it is known that Figure 2 In order to ensure the stable electrical connection between the panel 2 and the power supply base 1 and facilitate disassembly, the power supply base 1 is provided with at least one first interface 14, and the panel 2 is provided with a second interface 23 at the corresponding position. When the panel 2 is attached to the surface of the power supply base 1, the first interface 14 and the second interface 23 are conductive at the contact surface, thereby realizing the connection of the circuit.

[0031] Specifically, the second interface 23 is provided with at least two conductive contacts, and the first interface 14 is provided with elastic contacts at corresponding positions. When the panel 2 is installed on the power supply base 1, the conductive contacts abut against the elastic contacts to form stable electrical connection. The conductive contacts can be made of copper alloy, and the elastic contacts can be spring pins made of the same material and have certain elastic deformation capacity to ensure good electrical conductivity and mechanical strength. When the user aligns the panel 2 with the power supply base 1 and installs it in place, the conductive contacts of the second interface 23 abut against the elastic contacts of the first interface 14 to form stable electrical connection, which not only ensures the stability of power transmission but also supports signal transmission, so that the control circuit board 21 built-in the panel 2 can receive control signals from the power supply base 1 to control the pattern switching of the pattern display area 22.

[0032] In some embodiments, as shown in Figure 2 The power supply base 1 is provided with through holes 18 at the top and the edge of the side, and an arc-shaped channel is formed between the two through holes 18. A through hole 18 with a certain diameter is arranged between the top and the side of the power supply base 1, so that the user can fix the mobile power supply on a backpack or a key chain by a hanging rope, which is convenient for carrying.

[0033] In some embodiments, as shown in Figure 3 The power supply base 1 further includes a magnetically conductive metal frame 15 arranged at the upper and lower ends of the energy storage battery 11, and the panel 2 is embedded with a plurality of permanent magnets 24 corresponding to the magnetically conductive metal frame 15. The cooperation of the permanent magnets 24 and the magnetically conductive metal frame 15 ensures the accurate alignment and stable connection of the panel 2 during installation, and facilitates disassembly. Specifically, the power supply base 1 is provided with four recesses, and a neodymium iron boron permanent magnet 24 is embedded in each recess. The panel 2 is provided with a magnetically conductive metal frame 15 at a corresponding position. When the user aligns the panel 2 with the power supply base 1, the magnetic attraction between the magnetically conductive metal frame 15 and the permanent magnet 24 will automatically attract the panel 2 into place, ensuring accurate docking of the interfaces.

[0034] In another embodiment, as shown in Figure 3As shown, longitudinally extending slide rails 25 are symmetrically arranged on the inner wall of panel 2, and locking protrusions 251 are provided at the ends of slide rails 25; the outer surface of power base 1 is provided with guide grooves 16 that match the slide rails 25, and the inner wall of the grooves 16 is provided with limiting grooves 161 that cooperate with the locking protrusions 251. Specifically, two aluminum alloy slide rails 25 are provided on the inner wall of panel 2, and plastic locking protrusions 251 are provided at the ends. Two guide grooves 16 are provided on the outer surface of power base 1, and plastic limiting grooves 161 are provided on the inner wall of the grooves 16. In actual installation, the user only needs to align panel 2 with the guide grooves 16 on power base 1, and then push panel 2 along the direction of the grooves 16. The slide rails 25 will gradually embed into the guide grooves 16. When the locking protrusions 251 at the ends of the slide rails 25 reach the limiting grooves 161, the locking protrusions 251 will automatically embed into the limiting grooves 161. The locking protrusion 251 is a pressable structure. The user only needs to press the locking protrusion 251 to disengage it from the limiting groove 161, and then the panel 2 can be smoothly slid out along the slide groove 16.

[0035] Furthermore, the slide rail 25 and guide groove 16 can also work in conjunction with the interface and magnetic positioning assembly on the power supply base 1. The slide rail 25 and guide groove 16 ensure the physical alignment of the panel 2, while the interface and magnetic positioning assembly further enhance the stability of the connection and the reliability of the electrical connection. The longitudinal extension direction of the slide rail 25 is consistent with the electrical connection direction of the first interface 14 and the second interface 23, ensuring that the interface can accurately align during the assembly of the panel 2 and the power supply base 1, while the magnetic positioning assembly provides additional adsorption force to further prevent the panel 2 from loosening.

[0036] like Figure 2 As shown, in some embodiments, an image switching switch 17 is provided on the top of the power supply base 1. The image switching switch 17 is connected to the energy storage battery 11 inside the power supply base 1 via internal wires. The energy storage battery 11 is electrically connected to the control circuit board 21 built into the panel 2. When the user presses the image switching switch 17, the control circuit board 21 receives an electrical signal, triggering the pattern switching of the pattern display area 22. In actual use, the user can flexibly change the pattern on the panel 2 using the image switching switch 17 to meet the needs of different scenarios.

[0037] Specifically, the image switch 17 adopts a capacitive touch induction, supporting short-press switching of preset patterns and long-press switching of user-defined patterns. The touch induction unit 171 of the image switch 17 is connected to the main control circuit board 21 in the power supply base 1 through internal wires, and the main control circuit board 21 is electrically connected to the control circuit board 21 built in the panel 2. The touch induction unit 171 is built with a microcontroller, which can identify two operation modes of short-press and long-press. When the user short-presses the touch induction unit 171, the control circuit board 21 receives an electrical signal, triggering the pattern display area 22 to switch to the next pattern in a preset order, while when the user long-presses the touch induction unit 171, the control circuit board 21 triggers a different switching mode, such as quickly switching to a default pattern or entering a pattern editing mode.

[0038] In some embodiments, as shown in Figure 4 The control circuit board 21 is provided with a storage unit 211 and a communication module, and the communication module 212 supports Bluetooth or Wi-Fi protocol, for receiving custom pattern data sent by an external device and storing it to the storage unit 211. The control circuit board 21 is built with a Bluetooth module and a storage unit 211, and the user can send custom pattern data through a mobile phone App, and the Bluetooth module receives the data and stores it to the storage unit 211, and the user can select to display custom patterns through the image switch 17. When the user sends new pattern data to the mobile power supply through the App, the control circuit board 21 will store the data into the SD card and update the display content of the pattern display area 22. The user can switch to the new pattern by short-pressing the image switch 17, or quickly switch to the default pattern by long-pressing the switch.

[0039] In specific application scenarios, the user can connect the mobile phone APP with the communication module 212 of the mobile power supply, upload personalized pictures or dynamic expressions to the storage unit 211. For example, the user can set travel photos as the display content of the panel 2, or display real-time weather information through the LED dot matrix module. The control circuit board 21 can parse image data and drive the pattern display area 22 to update, while supporting multitasking processing, ensuring that the charging and discharging functions and the pattern switching do not interfere with each other.

[0040] In summary, the application provides a surface-skin-replaceable mobile power supply, which comprises a power supply base body and a panel. Through the detachable panel, a user can flexibly replace the pattern on the panel according to personal preferences or use scenarios, thereby meeting diversified and personalized appearance requirements. The pattern display area of the panel supports an electronic ink display screen or an LED dot matrix module, thereby further enhancing the diversity of display effects. A mechanical structure of a sliding rail and a guide sliding groove is adopted between the panel and the power supply base body, thereby ensuring stable installation and convenient disassembly of the panel. A locking protrusion at the end of the sliding rail cooperates with a limiting groove on the power supply base body, thereby providing a stable locking function and facilitating quick replacement of the panel by the user. The magnetic attraction force between a magnetically conductive metal frame and a permanent magnet automatically attracts the panel to a position, thereby preventing loosening of the panel.

[0041] It should be finally pointed out that the above embodiments are only used to illustrate the technical solutions of the application, rather than limit the protection scope of the application. Although the application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the application can be modified or replaced equivalently without departing from the essence and scope of the technical solutions of the application.
