Problems solved by technology

The existing protective cover mostly adopts the method of fastening the cover plate and the shell bolts. When the user installs the input and output point copper bars, all the bolts need to be disassembled, and then the bolts are reassembled after installation, which consumes a lot of disassembly and assembly man-hours

Abstract

The invention discloses a protective cover plate at the input and output ends of a battery disconnecting unit, comprising a protective cover, wherein one end of the protective cover is rotatably connected with the upper case of a distribution box, and the other end is connected with the lower case of the distribution box through a locking mechanism. The invention also provides a high-voltage distribution box adopting the protective cover plate, comprising a protective cover, an upper case, a lower case and a battery disconnecting unit. The input and output ends of the battery disconnecting unit are arranged at the surface recess of the lower case, and the protective cover covers the input and output ends of the battery disconnecting unit. The invention can enable the user to disassemble and assemble conveniently when installing the input and output point copper bar, and the operation is convenient and saves man-hour.

Description

technical field [0001] The invention relates to a high-voltage power distribution module of a new energy vehicle, in particular to a high-voltage power distribution box and a protective device for the input and output ends of a battery disconnect unit. Background technique [0002] The high-voltage power distribution box, referred to as the power distribution box, is the high-voltage power distribution unit in the high-voltage system solution of new energy vehicles. The battery disconnect unit (Battery Disconnect Unit, BDU), as a device for disconnecting and connecting the high-voltage power of the new energy vehicle power battery, plays a vital role in the safety of the battery pack. Most of the existing BDU high-voltage power distribution boxes place the battery module in the power distribution box shell, and use copper bars as input and output terminals. For safety reasons, protective cover components are required to cover the copper bars. The existing protective cover m...
