The power supply box body 1 is provided with a 4-core aviation head interface for connecting the sensor power supply and signal output, a cigarette lighter female head and a banana head interface for output power supply, and a 25-pin connector and a BNC connector for signal output conversion.

[0029] The power module supports a variety of sensors, including analog and digital types. Its power supply and signal transmission functions can flexibly adapt to the access requirements of different types and quantities of sensors. The module has a built-in voltage regulator module, which can output the input 10-16V DC voltage stably as 12V DC voltage, ensuring the stability and safety of power supply, and effectively preventing equipment damage or performance degradation caused by voltage fluctuations.

[0030] The power box 1 is equipped with a variety of universal interfaces, such as 4-core aviation connector, cigarette lighter female connector, banana connector, 25-pin connector and BNC connector, which are convenient for quickly connecting various sensors and realizing the transfer of power supply and signal output, thereby reducing the complexity of installation and debugging. Its design fully considers the application requirements of environments such as automotive testing, and has excellent anti-interference ability, compact structural design, and convenient installation and maintenance characteristics, ensuring stable and reliable operation in complex working environments.

[0031] The power module supports the access of up to 16 analog and 4 digital sensors, showing high scalability and flexibility, and can meet the diverse needs of sensor quantity and type changes in different application scenarios. Through the internal optimization design of the PCB board, efficient management of power supply and signal access is achieved, reducing the use of actual wiring harnesses, thereby reducing the risk of system heating and signal interference, and significantly improving the stability and accuracy of sensor signal transmission.

[0032] The power box body 1 includes a lower box body 11, a box cover 12 connected to the lower box body 11 by bolts, and an inner box body 16 for installing a voltage stabilizing module. The box cover 12 is provided with a plurality of first holes 13 for installing a 4-core aviation head interface, and the first holes 13 are distributed in an array. The box cover 12 is provided with a second hole 14 for installing a cigarette lighter female head and a banana head interface, and the second hole 14 is arranged on one side of the first hole 13.

[0033] In the design of the power box body 1, the lower box body 11 and the box cover 12 are connected by bolts, which significantly enhances the stability and tightness of the overall structure. This structural layout is not only convenient for maintenance and replacement of the power module when necessary, but also allows users to choose box covers 12 with different configurations according to actual needs, greatly improving the flexibility and customizability of the design. The surface of the box cover 12 is provided with an array of first holes 13, which are specially used to install a 4-core aviation head interface. This design simplifies the access and connection process of multi-channel sensors while ensuring the safety and stability of the connection.

[0034] In addition, a second hole 14 is provided on one side of the first hole 13 for installing a female cigarette lighter connector and a banana connector. This partition design not only facilitates users to quickly identify and select the correct connector, but also effectively reduces the risk of misconnection and wiring errors, significantly improving the operability and ease of use of the system.

[0035] Through the bolt connection design, the power box body 1 has excellent sealing and waterproof properties, and can work stably under various harsh environmental conditions. At the same time, the reasonable hole layout and interface installation position effectively prevent the intrusion of dust, water vapor and other impurities, thereby significantly extending the service life of the power module.

[0036] This design has significant advantages in the field of automotive testing, and can meet the needs of different sensor interfaces, covering multiple functions such as data acquisition, signal processing, and power supply. Its high flexibility and scalability make it widely used in various vehicle test equipment and systems, such as real-time monitoring, performance evaluation, and fault diagnosis.

[0037] The inner wall of the inner box body 16 is provided with a plurality of limit slots, which are arranged vertically. The side wall of the lower box body 11 is provided with a third hole body 15 for installing a 25-pin connector and a BNC connector.

[0038] The inner wall is provided with vertically arranged limit slots, which have effective limit and fixation functions and are specifically used to fix the electronic components or accessories installed inside the lower box body 11. This design ensures the stable position of the 25-pin connector, BNC connector and other potential internal components, and effectively prevents movement or loosening due to vibration or external impact. At the same time, the limit slots can significantly protect the electronic components installed inside the lower box body 11 from being adversely affected by the external environment. Especially in complex environments such as automotive testing, these slots are of great significance for reducing collisions between components and reducing the risk of damage.

[0039] On the side wall, a third hole 15 is specially designed for installing a 25-pin connector and a BNC connector. This design not only optimizes the installation and connection process of the interface, but also keeps the outside of the box neat and compact. Users can directly input and output signals through these interfaces, thereby simplifying the wiring and debugging process of the system. The designer fully utilizes the space inside the box and the side wall, and reasonably distributes the installation positions of the limit card slots and interfaces. This design not only improves the utilization efficiency of the internal space of the box, but also makes the layout of the internal components more compact and orderly, which helps to optimize the overall design structure and improve the appearance.

[0040] The installation and maintenance process is simplified through the reasonable setting of limit slots and the planning of interface installation positions. Users can more easily identify and access the required interfaces, reducing the risk of incorrect connections and operational errors, and significantly improving the convenience of use and operational efficiency.

[0047] Use 25-pin connector and BNC connector to transfer the output of sensor signal. 25-pin connector is used for output of digital and analog signals, while BNC connector is used for transmission of high frequency or analog signals.

[0048] When installing the module, the power module must be accurately installed at the designated location where power supply and signal processing are required, and ensure that it is firmly fixed and effectively grounded. This simple installation process greatly simplifies the installation steps and effectively reduces the complexity and time consumption during the installation process. Through the power cord, the power supply of the vehicle or system is connected to the input port of the power box 1. The built-in voltage regulator module then stabilizes the input voltage to 12V DC, ensuring that the connected sensors and other devices can operate at a stable operating voltage, thereby ensuring the accuracy and reliability of the test data.

[0049] The power box 1 is equipped with a variety of interface options, such as a 4-pin aviation connector, a female cigarette lighter connector, and a banana connector, designed to meet the connection requirements of different types and quantities of sensors. Users can choose the appropriate interface according to the specifications of the specific sensor, which greatly reduces the risk of wiring errors. In addition, the module also uses a 25-pin connector and a BNC connector for output transfer of sensor signals.
