Description

Technical Field

[0001] The utility model relates to a detection device for an electric motorcycle instrument panel. Background Art

[0002] An electric motorcycle is an electric vehicle similar in shape to a motorcycle and is one of the important means of transportation for people to drive using electric machinery in modern society. To ensure the safety of people during driving, an instrument panel is generally assembled on the head of an electric motorcycle to reflect the driving speed during driving.

[0003] However, during the production process of electric motorcycles, it is often found after the whole vehicle is assembled that the vehicle speed displayed on the instrument panel does not match the actual vehicle speed. Therefore, it is necessary to detect the instrument panel before the whole vehicle is assembled. However, traditional instrument panel detection devices are developed based on tests of constant voltage and constant speed under fuel motorcycles, while the battery voltage on electric motorcycles will change according to the usage time and cruising range of the battery. Therefore, traditional instrument panel detection devices cannot be fully applied to the detection of electric motorcycle instrument panels. Summary of the Invention

The other four switches are connected to the constant voltage source circuit and are respectively used to start and stop the detection of the display functions of the left turn signal, right turn signal, high beam, and low beam on the dashboard of the detected electric motorcycle.

[0010] Further, the voltage in the second adjustable voltage source is set to 48 - 72V.
