Description

Technical Field

[0001] The utility model relates to the technical field of manual opening tools, in particular to an opening tool used for a vehicle locking structure. Background Art

[0002] In recent years, the number of new energy MEB platform vehicles has exploded, and the professionalism of high-voltage system maintenance of new energy MEB platform vehicles has been continuously enhanced. Repairing the high-voltage system revolves around cutting off the high voltage, disconnecting the connection plug, and high-voltage testing. However, the tools for disassembling the locking structure of the high-voltage system plug are still operated with traditional vehicle maintenance tools (screwdrivers). This method has the following shortcomings:

[0003] From a cost perspective, the locking structure is a plastic card structure, and a metal screwdriver will cause damage to the plastic plug locking structure. Once the locking structure fails and is damaged, the entire high-voltage system plug structure must be replaced, increasing its maintenance cost. From a safety perspective, the screwdriver is a thin, flat metal structure with sharp edges and corners, which poses a risk of scratching high-voltage lines. From an efficiency perspective, since there are no special tools and the operating space is small and invisible, using random traditional tools for disassembly requires tentative attempts to open the locking plate structure, which has a high error rate and cannot be quickly opened at once. From an ease-of-use perspective, there are three common high-voltage plug locking structures, which are in different positions and require different types of tools.

[0004] Therefore, it is of great significance to provide a special tool for opening the high-voltage system plug locking structure of new energy MEB platform vehicles with sophisticated structure, non-metallic material, easy operation, multi-function and universality. Utility Model Content
