Description

TECHNICAL FIELD

[0001] The utility model battery pack plug -in technology field, specifically relates to a plug -in locking protection cover and battery pack one -time locking plug -in. BACKGROUND

[0002] The statements herein only provide the background of the utility model related, and not necessarily constitute the prior art.

[0003] With the development of new energy vehicles, people's demand for the endurance mileage of new energy vehicles is also improving. Among the schemes for improving the endurance mileage of new energy vehicles, there is a solution of fast replacing battery packs. The vehicle owner drives the vehicle with insufficient power to the designated replacement area and replaces the battery pack with insufficient power with a fully charged battery pack. In the process of replacing the battery pack, the battery pack plug-in is an essential component, which can realize the quick disassembly and installation of the battery pack.

[0004] The existing battery pack plug-in is basically of two types, one is a plug-in with secondary locking, and the other is a plug-in without secondary locking. The plug-in with secondary locking is generally more complex in application, such as water temperature sensing plug-in, high and low voltage plug-in of the whole pack, etc. The plug-in with secondary locking is designed to prevent the plug-in from being loosened when the primary lock of the plug-in is pressed or loosened. The correct sequence for loosening the plug-in is to first open the secondary lock of the plug-in, then open or press the primary lock of the plug-in, and then hold the plug-in with your hand to separate the male and female ends of the plug-in. The plug-in without secondary locking only needs to press the primary lock of the plug-in to separate the male and female ends of the plug-in. For the plug-in with only primary lock, when the space around the plug-in is insufficient, the primary lock of the plug-in may be pressed by the surrounding components. In this case, the male and female ends of the plug-in may be separated during the vibration of the battery pack, causing the connection to be disconnected and affecting the use of the battery pack.
