The circuit universal detection box contains a series of adjustable resistors, capacitors, inductors and other components, which can simulate different circuit conditions to help users diagnose and solve problems in the circuit. In the production process of new energy vehicles, it is necessary to detect the circuits of new energy vehicles, and then a circuit universal detection box will be used. Among them, the "A Multiplexed New Energy Vehicle Circuit Teaching and Detection Experiment Box" disclosed by the application number "CN202221093014.9" is also an increasingly mature technology, including a main box body, a circuit detection connection board and a replaceable circuit panel. The circuit detection connection board is installed in the main box body, and the replaceable circuit panel is installed on the upper end of the circuit detection connection board. The circuit detection connection board is provided with upper and lower rows of circuit terminal detection holes, and the circuit detection connection board is provided with 2 sets of DB25-pin male plugs corresponding to the external circuit inlet on the upper left side, and 2 sets of DB25-pin female plugs corresponding to the external circuit outlet on the upper right side. The utility model has low cost, easy maintenance, stronger practicality and expandability. The laboratory can purchase or produce more than 20 units at a time. For different car models or different electronic control system circuits, only the detachable and replaceable circuit panel can be replaced to realize the practical training of different circuit diagrams, so as to ensure that the equipment can keep up with the latest car model circuit diagrams in time. However, the circuit universal detection box will also be equipped with a display screen to facilitate the understanding of circuit data, and the display screen will refract when exposed to external light, which makes it inconvenient to understand the data fed back on the display screen. The circuit universal detection box is generally indoors when testing the circuit of new energy vehicles. At the same time, the room is generally equipped with lighting. If the light of the lighting lamp is irradiated on the display screen to produce refracted light, it will be inconvenient to understand the data. Utility Model Content
