Abstract

The invention discloses a battery pack box body and a vehicle with the battery pack box body. The battery pack box body comprises a cross beam arranged in the battery pack box body and a hanging column connected with the cross beam, wherein a first cavity extending in the length direction of the cross beam is formed in the cross beam, and penetrates through the cross beam, the hanging column penetrates through the side wall of the first cavity, and along the extension direction of the first cavity, plugging parts are respectively arranged on the two sides of the hanging column of the first cavity. According to the invention, the air tightness of the battery pack box body can be improved, and external liquid is prevented from entering the battery pack box body.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to a battery pack box body, a battery pack with the box body, and a vehicle with the battery pack. Background technique [0002] The lifting point structure of the battery pack box refers to the structure used to fix the vehicle, and the battery pack box is usually provided with a hanging point structure set through it. Due to the vibration and impact of the vehicle during driving, the lifting point is the concentrated point of force, so the welding seam of the lifting point structure of the battery pack box is easy to crack, which reduces the airtightness of the battery pack box, causing external liquid to enter the battery Inside the box. Contents of the invention [0003] The object of the present invention is to provide a battery pack case capable of improving airtightness, a battery pack with the case, and a vehicle with the battery pack against the sho...
