[0023] In order to make the purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in combination with the drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0024] With reference to Figs. 1-3 , a power bank provided by an embodiment of the present application is shown, which comprises: a shell 101, in which a secondary battery 202 and a PCB main control board 201 are arranged; the shell 101 is externally covered by an FPC 102; a power supply interface is arranged at a position not covered by the FPC 102; the secondary battery 202, the FPC 102 and a power supply connector are electrically connected to the PCB main control board 201; and an indicator lamp and / or a display screen are arranged on the FPC 102.

[0025] In the embodiment of the present application, the power supply interface can provide a charging interface for a target and also serve as a charging interface of the power bank; the display screen arranged on the FPC 102 solves the problem that the traditional power bank only uses an LED lamp to display the power, and cannot display specific power value, voltage, current, decorative pattern and other information. In the technical solution, the connection between the PCB main control board 201 and the secondary battery 202 can obtain battery information and intuitively display specific power, voltage, current, decorative pattern information on the display screen, solving the problem of incomplete power display of the traditional power bank. In addition, in the past, some power banks with LED display screens need to specially set up independent mounting positions for the display screens, which increases the design complexity and affects the appearance. In the present solution, the FPC is covered outside the shell, and the flexible feature of the FPC can be used to flexibly integrate the indicator lamp and / or the display screen on the FPC, without the need for additional complex structure design to place the display screen and other components, which simplifies the design process, reduces the structural complexity caused by the special setting of the display screen mounting position, and makes the overall appearance of the power bank more simple and beautiful. Because the FPC can be attached to the shape of the shell, there is no protruding display screen mounting structure.

[0026] Through the above structure, the user can know the remaining power, voltage, current of the power bank at any time, and can also obtain aesthetic value through the decorative pattern, so as to facilitate the user to reasonably arrange the charging plan, for example, when going out, the user can accurately judge whether other devices need to be charged according to the remaining power, or prepare to charge the power bank in advance, which greatly improves the convenience and experience of the user using the power bank. Since the position for installing the display screen does not need to be designed, the simplified design structure reduces the process difficulty and cost in the production and manufacturing process, and reduces the cost of mold development, assembly and other links that may be caused by complex structure design. By setting the light emitting element on the FPC 102, for example, the surface-mounted LED and the corresponding supporting circuit components, the FPC 102 has a light emitting effect; it is more in line with the trend of modern consumers' high aesthetic requirements for the appearance of electronic products, and can attract more consumers' attention and purchase, which helps to expand the share of the power bank in the consumer market, and has strong attraction for both the general consumer market and some high-end or special-purpose markets (such as gift markets) with high requirements for appearance design.

[0027] In the following, one of the power banks in the various exemplary embodiments of the present application will be further described.

[0028] In the embodiments of the present application, a power bank, wherein the FPC 102 is provided with LED light source components and supporting circuit components. The surface of the FPC 102 is provided with a protective film.

[0029] Further, the surface of the protective film is at least partially coated with fluorescent powder to realize the change of the color of the LED. In this case, the FPC 102 is provided with LED light source components, and a translucent film that can transmit light and limit the light area is covered. The film can be optionally coated with fluorescent powder to realize the change of the color of the LED. The corresponding numbers and patterns can be set on the protective film in combination with the coated fluorescent powder, so as to display simple numbers and color patterns, and the colorful display and information richness are improved:

[0030] By coating the fluorescent powder on the surface of the protective film to realize the change of the color of the LED, and by setting the numbers and patterns in combination, the power bank can not only display basic information such as power, but also present more diversified content in the form of color patterns and numbers. For example, different colors of warning can be displayed according to the power, a red warning pattern is displayed when the power is low, a yellow color is displayed when the power is medium, and a green color is displayed when the power is high. At the same time, simple digital information such as charging speed and battery health status can also be displayed, which greatly enriches the information dimension conveyed by the power bank to the user, and improves the visual effect and information interaction.

[0031] In addition, the power bank can present rich color patterns and digital combinations on the surface, and can meet the needs of different users for personalized appearance. Whether it is a simple power digital display with a fresh fluorescent background or a creative color pattern decoration, the power bank can stand out in appearance and be different from traditional monotonous power bank design, and has more attraction in many similar products, further improving the beauty and uniqueness of the product.

[0032] In the embodiment of the present application, the protective film is a transparent or translucent film, which can be pasted on the FPC 102 in a back adhesive manner. The protective film is further provided with a transparent or translucent plastic shell. The FPC 102 (flexible circuit board) is arranged on the shell 101 and pasted on the product shell in a back adhesive manner, and is connected to the product PCB main control board 201 in an electrical connection manner, so as to protect the screen. A transparent or translucent plastic shell can be added outside the FPC 102 and the corresponding screen, or the transparent or translucent plastic shell can cover the entire FPC 102, so as to strengthen the protection of the FPC 102. For example, when the power bank is squeezed or impacted, the transparent or translucent plastic shell can first unload part of the force, preventing damage to the FPC 102 by external force. The entire shell 101 can also be provided with a plastic shell.

[0033] In the embodiment of the present application, the power interface is provided with a male head and / or a female head, including a TYPE-C interface 103, a MICRO-USB interface and a Lightning interface 104. As shown in Fig. 1 The power interface is a TYPE-C interface 103 and a Lightning interface 104. The TYPE-C interface 103 is a female head, which is arranged on the surface of the shell 101 and used for plugging a charging line, i.e. can be used as an output interface and an input interface, i.e. can be used as a device for supplying power to a target device or as an interface for charging the power bank. The Lightning interface 104 is a male head, which is used for plugging an Apple device. Since the TYPE-C interface 103 is commonly used at present and the technology is mature, it can be used as an input interface and an output interface. The Lightning interface 104 can be connected by a wire and can be provided with a storage space in the shell. Specifically, it can be similar to the contraction structure in a tape measure. When it is needed to use, the wire is pulled out of the shell 101, and after use, the wire is pulled outwards to make the wire contract into the shell 101, and only the Lightning interface 104 is exposed.

[0034] It should be noted that the Lightning interface 104 can also use a multifunctional connector, for example, a three-in-one connector, i.e. a connector integrating a TYPE-C interface 103, a MICRO-USB interface and a Lightning interface 104.

[0035] As Fig. 2 shown, one end of the shell 101 is also provided with a function button 105, which is electrically connected to the PCB main control board 201. The function button 105 can be used as an on-off key or a state display button, or as an on-off key and a state display button. For example, when pressed normally, it is used as an on-off key, and when pressed quickly, it is used as a state display, which can display the power, charging current and temperature of the power bank.

[0036] It should be noted that the temperature state needs to be matched with a temperature sensor, such as a temperature sensing resistor, and the temperature sensor and application circuit are conventional technical means, which will not be described here.

[0037] Although the preferred embodiments of the present application have been described, those skilled in the art can make further changes and modifications to the embodiments once they know the basic inventive concept. Therefore, the appended claims are intended to cover all changes and modifications falling within the scope of the embodiments of the present application.
