Power battery mounting frame

The utility model belongs to the technical field of new energy, and particularly relates to a power battery mounting frame. Comprising at least two U-shaped frames which are parallel to each other; the number of the longitudinal beams is two, the longitudinal beams are parallel to each other, and each longitudinal beam is connected with the U-shaped frame to form a quadrilateral frame structure; each bottom sealing plate is mounted in the corresponding quadrilateral frame structure; the waist-shaped holes are symmetrically formed in each U-shaped frame, so that the U-shaped frames are connected with a frame; according to the utility model, the U-shaped frame, the longitudinal beams, the reinforcing plate and the like are fixedly connected to form the main body frame with the three-dimensional accommodating space, so that the main body frame can be mounted between the two longitudinal beams of a vehicle frame, and the problem that the wheelbase is increased when the battery frame is arranged on the back of a v
