Battery pack case, battery pack, and vehicle

Abstract

This application provides a battery pack housing, a battery pack, and a vehicle. The battery pack housing includes: a frame assembly including a first side beam and a second side beam, the first side beam extending along a first direction and the second side beam extending along a second direction, the first side beam having a plug-in protrusion and the second side beam having a slot, the plug-in protrusion being plugged into the slot, the first direction and the second direction intersecting; a first sealing layer located between the plug-in protrusion and the slot wall; and a fastening assembly connecting the plug-in protrusion and the slot wall. In this application, the first side beam and the second side beam of the frame assembly are first connected together by plugging, with a first sealing layer between them, and then fixedly connected by the fastening assembly. This improves the sealing performance of the battery pack housing while reducing its production cost.
