[0030] The following will be combined with Figures 1 to 3 , and the multi-functional composite PCB power supply device provided by the embodiments of the present application will be described in detail through specific embodiments.

[0031] Please refer to together Figures 1 to 3, the multi-functional composite PCB power supply device 100 provided by one embodiment of the present utility model includes a battery box 10, a battery module 20, a PCB board 30, a collection module 40 and an upper cover 50. A receiving space is provided inside the battery box 10, and charging and discharging terminals are provided on the battery box 10; the battery module 20 is disposed inside the receiving space, and the battery module 20 is connected to the charging and discharging terminals to realize the charging and discharging functions of the multi-functional composite PCB power supply device 100; the PCB board 30 is connected to the battery module 20 to realize the series connection and data collection between the batteries in the battery module 20; the collection module 40 is connected to the PCB board 30, and data delivery can be performed between the collection module 40 and the PCB board 30; the upper cover 50 is detachably connected to the battery box 10.

[0032] The mutual connection between the PCB board 30 and the battery module 20 can better manage the batteries in the battery module 20 through series connection and data collection, which enables the batteries to maintain a better state for a long time and delays the aging of the batteries.

[0033] By providing charging and discharging terminals on the battery box 10 and placing the battery module 20 inside the battery box 10, the battery module 20 is connected to the charging and discharging terminals, thereby realizing the charging and discharging functions of the power supply device.

[0034] The use of the PCB board 30 reduces the number of materials and connection points, which can simplify the internal assembly process of the device. And the PCB board 30 can better manage the series connection between the batteries and collect data, improving the performance and reliability of the device. In addition, the design of the PCB board 30 can reduce the use of wire harnesses, reducing the risks of circuit failures and safety hazards. Through such a setting, the internal structure process of the power supply device is simple and the use of materials is reduced.

[0035] The upper cover 50 is detachably connected to the battery box 10. When the upper cover 50 is covered on the battery box 10, the battery box 10 is closed, which can protect its internal structure (such as the battery module 20, the PCB board 30); when the upper cover 50 is separated from the battery box 10, it is convenient to replace components such as the battery module 20 or the PCB board 30.

[0036] In some embodiments, the PCB board 30 includes a body portion 31 and a fixing member 32. Fixing holes are provided on both the body portion 31 and the battery module 20; the fixing member 32 sequentially passes through the fixing holes of the battery module 20 and the fixing holes of the body portion 31 to fix the battery module 20 on the PCB board 30.

[0037] By aligning the fixing holes of the battery module 20 and the fixing holes of the PCB board 30, and then using a fixing member 32 (such as a screw, a plug, etc.) to pass through, the battery module 20 can be firmly installed on the PCB board 30. This installation method is simple and fast, facilitating production and maintenance.

[0038] Specifically, the fixing member 32 passes through the fixing holes of the battery module 20 and the PCB board 30, forming a stable connection. This connection method can effectively transfer current and mechanical stress, ensure reliable electrical connection between the battery module 20 and the PCB board 30, and avoid poor contact or loosening.

[0039] In some embodiments, a copper plate 311 is provided on the body portion 31, and the battery module 20 is provided with positive and negative electrode posts 21, and the positive and negative electrode posts 21 are electrically connected to the copper plate 311.

[0040] The copper plate 311 has good electrical conductivity, and the battery can conduct electricity through the contact surface between the positive and negative electrode posts 21 and the copper plate 311. Since the copper plate 311 has good overcurrent capacity, large current conduction can be achieved.

[0041] In some embodiments, the PCB board 30 further includes an exposed copper foil surface 33, a collecting copper foil line 34, and a collecting communication terminal 35; the exposed copper foil surface 33 is electrically connected to the copper plate 311; one end of the collecting copper foil line 34 is connected to the exposed copper foil surface 33, and the other end is connected to the collecting communication terminal 35.

[0042] By connecting the collecting copper foil line 34 to the exposed copper foil surface 33, the resistance of the current during transmission can be reduced, the electrical conductivity of the power supply device can be improved, and the efficient transmission of electric energy can be ensured. The collecting communication terminal 35 can be used to collect the working parameters and status information of the power supply device, etc. By connecting the exposed copper foil surface 33 to the collecting communication terminal 35 through the collecting copper foil line 34, these signals can be collected more accurately, and the accuracy and stability of signal collection can be improved. Integrating the collecting copper foil line 34 and the collecting communication terminal 35 on the PCB board 30 can simplify the circuit design of the power supply device, reduce the use of external connections and wire harnesses, and improve the reliability and maintainability of the device. And the exposed copper foil surface 33 is usually connected to the radiator or metal shell of the power supply device to form a good heat dissipation path. The setting of the collecting copper foil line 34 can increase the heat dissipation area, help to better dissipate heat, and improve the heat dissipation performance of the power supply device. The collecting communication terminal 35 is used to transmit signals and is easily affected by external interference. Connecting the collecting copper foil line 34 to the exposed copper foil surface 33 can provide a low-impedance path, reduce the influence of electromagnetic interference on the signal, and improve the anti-interference ability of the device. Integrating the collecting copper foil line 34 and the collecting communication terminal 35 on the PCB board 30 can ensure the connection quality and consistency between various components, and improve the quality stability of the product. By reasonably arranging the collecting copper foil line 34 and the collecting communication terminal 35, the layout of the PCB board 30 can be made more compact, effectively utilize the space, and meet the installation requirements of different devices.

[0043] In some embodiments, the PCB board 30 further includes a temperature collector 36, which is connected to the acquisition communication terminal 35. An NTC resistor is soldered on the temperature collector 36. The NTC resistor can sense the temperature change on the PCB board 30 and convert it into an electrical signal, which is transmitted to an external device or system through the acquisition communication terminal 35. In this way, the temperature of the power supply device can be monitored in real time, and abnormal temperature conditions can be detected in time to avoid failures or damages caused by overheating. Soldering the temperature collector 36 and the NTC resistor on the PCB board 30 realizes the integration of the temperature detection function, reduces the complexity of external sensors and connections, and improves the overall reliability and compactness of the system.

[0044] In some embodiments, a module pressing plate 60 is further included. The module pressing plate 60 is disposed in the battery box 10 and connected to the battery module 20. The module pressing plate 60 can fix the battery module 20 in the battery box 10, thereby preventing the battery module 20 from shifting in the battery box 10, and thus preventing poor contact between the battery module 20 and the interfaces (such as charging ports, discharging ports, etc.) on the battery box 10.
