New energy automobile battery pack support

Abstract

The invention discloses a new energy automobile battery pack support. The support comprises a first horizontal plane, a vertical plane, a second horizontal plane, an inclined plane, a first side faceand a second side face, wherein the first horizontal plane, the vertical plane, the second horizontal plane and the inclined plane are adjacent to one another, and the first side face and the second side face are symmetrically located; the first horizontal plane is attached to and fixed to the upper surface of a battery pack protruding part; the vertical plane is attached to and fixed to one vertical side face of the battery pack protruding part; the second horizontal plane is located in the transition area of the battery pack protruding part and a ground board cross beam; one part of the second horizontal plane is attached to and fixed to the bottom flange of the battery pack protruding part, and the other part of the second horizontal plane is suspended; and the inclined plane is attached to and fixed to the ground board cross beam. According to the new energy automobile battery pack support of the invention, two such supports can be installed between the battery pack protruding partand the disconnected ground board cross beam, so that the ground board cross beam and the battery pack protruding part are connected into a whole cross beam from left to right, and therefore, the continuity of the rigidity of the cross beam is improved, the intrinsic modes of floor and the battery pack are strengthened, and structural noise caused by the modes is reduced.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing, and in particular relates to a new energy automobile battery pack bracket. Background technique [0002] At present, the NVH (Noise, Vibration, Harshness, noise, vibration and harshness) performance research of domestic automobiles is mainly aimed at traditional automobiles, while the NVH performance research on new energy vehicles is still in its infancy. With the rapid increase in the number of new energy vehicles in China, the customer groups have higher and higher requirements for the NVH performance of new energy vehicles. Most of the new energy models on the market generally increase the number of battery packs to meet customers' needs for cruising range. The increase in the number of battery packs leads to an increase in the volume of the battery pack, which leads to a decrease in the NVH optimization space of the car, resulting in an unreasonable structure, specifically ...
