Description

Technical Field

[0001] This utility model belongs to the fields of sharing economy, technology consumption, smart Internet of Things and urban infrastructure, and in particular relates to a shared power bank device that can be powered by a mobile power source and charged externally. Background Technology

[0002] With the rapid development of the sharing economy, shared power banks, as a convenient mobile charging solution, have gradually become popular in the market. Their core purpose is to solve the problem of insufficient battery power for mobile devices such as smartphones when users are out and about, providing flexible charging services. However, existing shared power bank devices have many technical shortcomings in practical applications, as follows:

[0003] Traditional shared power bank cabinet systems rely on external 220V power supplies, making it impossible to provide power bank rental services properly in scenarios without external power or where wiring is inconvenient (such as outdoor camping, temporary exhibitions, and remote areas), severely limiting the scope of equipment use. Traditional shared power bank cabinets use an external plug-in connection for the power cord, requiring manual insertion before use, which not only increases operational steps but also poses safety risks such as poor contact and leakage. Traditional shared power banks lack external charging interfaces; when users fail to return them within the designated time, the power bank cannot be recharged using a conventional charging cable, ultimately rendering it unusable and wasting resources. Furthermore, traditional shared power bank cabinets, designed for added functionality, have complex structures and cumbersome assembly processes, increasing production difficulty, reducing assembly efficiency and first-pass yield, and raising production costs.

[0004] Therefore, developing a shared power bank device that can reduce production costs, overcome usage scenario limitations, and improve safety and resource utilization has become a pressing technical challenge for the industry. Utility Model Content

[0005] The purpose of this utility model is to provide a shared power bank device that is powered by a mobile power source and can be externally charged, aiming to solve the problems existing in the background technology. To achieve this purpose, the technical solution adopted by this utility model is:

[0006] A shared power bank device with external charging capability powered by a mobile power source includes a power bank and a charging cabinet, wherein the power bank is detachably installed inside the charging cabinet; the charging cabinet includes a front shell, a rear shell, and functional components, wherein the functional components are disposed inside the front shell and the rear shell.

[0007] The functional components include a display screen, a circuit board, an electronic lock assembly, a communication interface circuit board, a first USB charging port, a waterproof pad, a charging cable, and a charging device. The charging device is installed in the middle of the front shell and is used to place and connect to the power bank. A display screen is located above the charging device to display device status, rental information, etc. The communication interface circuit board is located at the rear of the charging device, and a first USB charging port is located on one side of the communication interface circuit board. The first USB charging port is a Type-C universal USB interface, which is connected to the circuit board through a Type-C 4-pin terminal to realize communication and independent power supply functions. When there is no 20V external power, an external mobile power supply can be connected to this interface to power the charging cabinet. The charging cable passes through the rear shell and connects to the communication interface circuit board. A waterproof pad is provided at the connection point between the charging cable and the rear shell, and the charging cable adopts a U-shaped structure design to directly enter the inside of the cabinet. The waterproof pad and the U-shaped structure achieve the effects of waterproofing, preventing leakage, and strengthening fixation.

[0008] The power bank is connected to the charging device. The power bank is equipped with a second USB charging port, which is a Type-C universal USB interface. It is connected to the internal circuit board of the power bank through a Type-C 4-core connector to realize communication and charging functions, thus solving the problem that the power bank can only discharge and cannot charge after leaving the charging cabinet.

[0009] Meanwhile, the charging cabinet adopts a three-module assembly design of front shell, middle part (functional component integration part) and rear shell through structural optimization, which simplifies the assembly process and improves production convenience.

[0010] The beneficial effects of this utility model are:

[0011] Breaking through usage scenario limitations: By setting up a first USB charging port (type-C universal USB interface) on the charging cabinet, in scenarios without 220V external power, ordinary power banks can be directly connected to this interface to power the device, ensuring that the device can provide rental services normally and greatly improving the device's environmental adaptability.

[0012] Enhanced safety and convenience: The power cord of the charging cabinet is designed to be directly connected to the inside, with a waterproof pad and U-shaped structure, eliminating the need to plug in the power cord before use. This also effectively solves safety risks such as poor contact and leakage, and simplifies the operation steps.

[0013] Reduce resource waste: By setting a second USB charging port (type-C universal USB interface) on the power bank, when the user does not return the power bank within the time limit, the power bank can be charged by connecting to this port with a regular charging cable, so that it can be used again. This avoids the situation where the power bank is scrapped due to depletion of power and makes full use of the value of the device.

[0014] Reduced production costs and improved efficiency: The charging cabinet adopts a three-module assembly design of front shell, middle part and back shell, which simplifies the structural complexity, makes assembly and production more convenient and simple, and less prone to errors, effectively reducing production costs and improving assembly efficiency and production first pass rate.
