The invention discloses a structure integrating a battery pack and a vehicle body and a vehicle. The structure integrating the battery pack and the vehicle body comprises a frame front main beam, a frame cross beam and the battery pack; the frame front main beam comprises an inner-side main beam with a U-shaped cross section and an outer-side main beam arranged at a U-shaped opening, a cavity is formed between the inner-side main beam and the outer-side main beam, and the side, away from the U-shaped opening, of the inner-side main beam is connected with a base plate; the frame cross beam comprises a first flange used for being welded to the outer-side main beam and a second flange used for being welded to the base plate. According to the technical scheme, the base plate of the battery pack is welded to the frame front main beam and the frame cross beam, a battery pack mounting bracket is not involved, the battery pack and the vehicle body are integrated, and the problems that batterypack mounting brackets are unsuitable in size, difficult to assemble and the like are also solved; in addition, the cavity is formed in the frame front main beam, the rigidity of the frame front mainbeam can be improved, the side-collision impact force is reduced, the collision deformation is absorbed, and therefore the battery pack is protected.
Description
technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a battery pack body integrated structure and a vehicle. Background technique [0002] At present, traditional new energy electric vehicles often install and fix the battery pack 3 on the front frame 1 of the frame through the battery pack mounting bracket 4. For the specific structure, please refer to figure 1 , this installation method has the following defects: the strength of the battery pack mounting bracket 4 is insufficient, there is a risk of failure, which affects safety performance; the number of battery pack mounting brackets 4 is too large, it is difficult to ensure the matching size, and assembly is difficult. Contents of the invention [0003] The main purpose of the present invention is to provide a battery pack body-integrated structure and an automobile, aiming to solve the technical problems of insufficient strength and excessive use of battery pack m...
