Description

Technical Field

[0001] This utility model relates to the field of mobile power bank testing technology, and more specifically, to a mobile power bank aging cabinet. Background Technology

[0002] A power bank (portable power bank) is a portable device that stores electrical energy through a built-in battery to provide emergency power to mobile phones and other devices. Aging testing, simply put, "simulates long-term use" to expose potential problems early—such as battery degradation and circuit failures—ultimately ensuring user safety and durability. The testing process revolves around "repeated charging and discharging + extreme environmental testing," using scientific methods to select qualified products.

[0003] Lithium batteries have a "cycle life" (generally, after 500-1000 charge-discharge cycles, the capacity will drop to less than 80% of the initial value). Aging testing, by simulating repeated charge-discharge cycles, can quickly determine whether the battery is degrading too rapidly. For example, if a power bank is labeled as 10000mAh, but after 100 cycles the capacity is reduced to only 5000mAh, it clearly does not meet durability requirements. Inferior power banks may experience overcharging, overheating, short circuits, and fires during long-term use due to circuit design defects (such as protection module failure). Aging testing exposes these potential risks under extreme conditions (such as high-temperature environments), hence the provision of a power bank aging cabinet. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a mobile power bank aging cabinet, which aims to solve the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a mobile power bank aging cabinet, including a cabinet, on which a detection component is provided;

[0006] The detection component includes a cover plate on the top of the housing, with several indicator lights embedded in the cover plate, and two wiring modules provided at one end of the cover plate;

[0018] 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.

[0019] This embodiment discloses a power bank aging cabinet, which aims to solve the problems of messy wiring, low testing efficiency and poor heat dissipation in existing power bank aging testing equipment.

[0020] Specifically, as shown in the attached document Figure 1 As shown, the power bank aging cabinet includes a housing 1, which is a rectangular frame structure that provides a stable installation space for the internal components.

[0021] As attached Figure 1 and attached Figure 4 As shown, a cover plate 2 is embedded in the top of the housing 1, and several indicator lights 3 are embedded in the cover plate 2. The indicator lights 3 can be LED lights of model LTST-C191KRKT. Green LED lights are used to indicate that the corresponding power bank is detected normally, and red LED lights are used to indicate that the corresponding power bank is detected abnormally. Each indicator light 3 is connected to the PCB board 11 through wires, and its on / off state is controlled by the PCB board 11.

[0022] As attached Figure 1 As shown, two wiring modules 4 are provided at one end of the cover plate 2. (See attached diagram) Figure 2 As shown, each of the two wiring modules 4 has several staggered openings 5. The staggered openings 5 ​​are designed to prevent interference when connecting adjacent terminals 7. Each staggered opening 5 has a gasket 6 made of silicone, which provides insulation and cushioning to prevent direct contact between the terminal 7 and the wiring module 4, thus preventing a short circuit. Multiple gaskets 6 have terminals 7, which can use an XT30PW-M plug for stable connection to the charging / discharging interface of the power bank.

[0023] As attached Figure 1 and attached Figure 3As shown, a processor 8 is provided on one side of one end of the cover plate 2. The processor 8 can be a single-chip microcomputer of model STM32F103C8T6. Its function is to receive the detection data transmitted by the PCB board 11, analyze and process it, control the state of the indicator light 3, and realize the control of the charging and discharging cycle of the mobile power supply. It supports multi-channel independent detection and control.

[0024] As attached Figure 3 As shown, a PCB board 11 is provided at the bottom of the cover plate 2, which serves as a carrier for circuit connections, enabling signal transmission and power distribution between various electrical components. An external plug 9 is provided on the PCB board 11, which is used to connect to an external AC power source to power the entire device.

[0025] As attached Figure 1 and attached Figure 3 As shown, the wiring module 4 is located on the top of the PCB board 11 and is connected to the PCB board 11 through wires to ensure stable current transmission.

[0026] As attached Figure 1 and attached Figure 4 As shown, the bottom of the housing 1 is provided with a number of heat dissipation holes 10, and each heat dissipation hole 10 is provided with a dustproof filter element, which can effectively block dust from entering the housing 1 without affecting the heat dissipation effect.

[0027] The specific working principle is as follows: Before testing, the power bank to be tested is connected to terminal 7 via wires, with each terminal 7 corresponding to one power bank. Power is turned on via external plug 9, and the power is converted by the power module on PCB board 11 to power the entire device.

[0028] After the processor 8 starts up, it sends control signals to the wiring module 4 through the PCB board 11 to control the power bank to perform charge and discharge cycle tests. During the test, a current sensor (model ACS712ELCTR-05B) and a voltage sensor (model INA219) can be installed on the PCB board 11 to collect the current and voltage data of the power bank in real time and transmit the data to the processor 8.

[0029] The processor 8 analyzes the collected data. If all parameters of the power bank are normal, it controls the corresponding green indicator light 3 to light up. If an abnormality is detected, such as excessive charging or discharging current or abnormal voltage, it controls the corresponding red indicator light 3 to light up. The test circuit of the power bank can be cut off and the test can be stopped by installing a G5V-1-12VDC relay on the PCB board 11.

[0030] During the testing process, heat is generated inside the enclosure 1. The heat is dissipated to the outside through the heat dissipation holes 10 at the bottom. The dust filter can prevent external dust from entering the enclosure 1 and avoid dust affecting the normal operation of electrical components.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
