They offer users a convenient charging solution, eliminating the worry of running out of phone battery. They offer a convenient, flexible, and economical charging solution that meets the needs of modern, fast-paced lives and prevents phone battery drains while out and about. Most shared power banks utilize QR code scanning, which directs users to a fixed link for payment. This allows for fast and convenient transactions, eliminating the need to carry cash or credit cards and enabling payments anytime, anywhere. This highly efficient, easy-to-use method eliminates the need for change and other complexities.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-5 , the utility model provides a technical solution:

[0029] A touch-sensitive QR code backlight comprises a component mounting frame 1 with a partition 4 disposed in the middle. Flanking the partition 4 are slots for a touch switch and a QR code backlight, respectively. The slots house corresponding touch switches and QR code backlight units. A component panel 5 is disposed on the component mounting frame 1 at locations corresponding to the touch switches and QR code backlight units. The component mounting frame 1 is fixedly mounted on one side of a power bank. The device is powered by a power bank and illuminates the QR code when pressure or contact is applied, making it very convenient to use.

[0030] Furthermore, the power bank is provided with a component fitting groove 2 corresponding to the component fixing frame 1. The component fixing frame 1 is snap-fitted and fixed in the component fitting groove 2. A structural groove 3 is provided on the power bank corresponding to the backlight portion of the QR code. The component fitting groove 2 and the component fixing frame 1 can be provided with movable buckles or adhered with adhesives. The structural groove 3 can be omitted. The corresponding circuit board 10 can be placed in the charging and discharging circuit of the power bank. In this case, the QR code must be placed in the corresponding position of the power bank's circuit structure.

[0031] Furthermore, the component panel 5 is made of transparent glass or resin. The function of the component panel 5 is to protect the internal components and prevent them from being damaged by pollution or water ingress.

[0032] Furthermore, the QR code backlight portion includes a replaceable QR code component and a light-emitting component.

[0033] Furthermore, the QR code component includes a hard card 6 and a card fixing shell 7. The card fixing shell 7 is snapped into the notch corresponding to the QR code backlight portion on the component fixing frame 1. The side walls of the card fixing shell 7 abut against the partition 4 and the inner side wall of the component fixing frame 1. The card fixing shell 7 is provided with an avoidance hole corresponding to the hard card 6. A card slot 8 is provided on one side of the card fixing shell 7. The hard card 6 is slidably snapped into the card slot 8. A convenient notch 9 is provided on the card fixing shell 7 corresponding to the card slot 8. The convenient notch 9 is used to quickly remove the hard card 6 from the card slot 8. The card fixing shell 7 not only serves as a fixed limit, but also facilitates the replacement of different QR codes through the cooperation of the card fixing shell 7 and the hard card 6. When changing the QR code, it is only necessary to replace the hard card 6 printed with a different QR code.

[0034] Furthermore, the hard card 6 is a transparent PVC sheet, and a QR code pattern is printed on the hard card 6. The use of a transparent PVC sheet is low in cost, and the printing technology on the PVC sheet is mature, and only a dark ink is needed to print a QR code image on a transparent background.

[0035] Furthermore, the light-emitting component includes a circuit board 10 and an LED lamp bead 11. The circuit board 10 is fixedly installed in the structural groove 3 and is electrically connected to the power bank. The circuit board 10 is provided with an LED lamp bead 11. The circuit board 10 should be provided with a current detection circuit and an electronic switch. When the piezoelectric touch switch is triggered, that is, when it is subjected to pressure, it will generate current. This current signal is used as a device trigger signal to connect the circuit of the LED lamp bead 11 to the electronic switch. The LED lamp bead 11 will emit light to illuminate the QR code above, achieving a backlight effect.

[0036] Furthermore, the touch switch portion includes a flexible insulating layer 12, a piezoelectric material layer 13, and a rigid insulating layer 14. The flexible insulating layer 12, piezoelectric material layer 13, and rigid insulating layer 14 are sequentially arranged on the side of the component panel 5 adjacent to the power bank. These layers are tightly connected and snap-fastened into the notch of the touch switch portion. The piezoelectric material layer 13 is electrically connected to the circuit board 10. This touch switch is based on the piezoelectric effect. When a user touches the switch surface, the piezoelectric material is subjected to pressure, resulting in a change in charge. This charge change is converted into an electrical signal, which is processed by a circuit and ultimately triggers the switch. Because the piezoelectric material does not generate current when not being touched, a piezoelectric touch switch consumes almost no power when not in operation. Although inductive touch switches offer greater precision and sensitivity, they only require a single signal for the power bank backlight. Using a piezoelectric touch switch reduces costs and consumes very little power in standby mode.

[0037] Working principle: When using this device, the user touches the power bank and the pressure changes. The piezoelectric material layer 13 is squeezed to generate a weak current. The current signal triggers the electronic switch to connect the circuit of the LED lamp bead 11. The LED lamp bead 11 emits light to illuminate the QR code above it, making it convenient for the user to scan the QR code. The QR code is printed on a transparent hard card, which is slidably connected to the card fixing shell. The QR code can be changed by replacing the card with a different QR code.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
