The invention belongs to the technical field of automobile bodies, and relates to a battery pack side impact protection frame and an automobile. The battery pack side impact protection frame includes the front beam of the driver's seat, the rear beam of the driver's seat, the left protective beam of the battery pack, the front beam of the passenger's seat, the rear beam of the passenger's seat and the right protective beam of the battery pack. The right end of the front beam of the driver's seat is fixedly connected to the front end of the left protective beam of the battery pack, the right end of the rear beam of the driver's seat is fixedly connected to the rear end of the left protective beam of the battery pack, and the front of the driver's seat The crossbeam is located in front of the rear crossbeam of the main driver's seat; the left end of the front crossbeam of the passenger seat is fixedly connected to the front end of the right protective longitudinal beam of the battery pack, and the left end of the rear crossbeam of the passenger seat is connected to the rear of the right protective longitudinal beam of the battery pack. The ends are fixedly connected, and the front crossbeam of the passenger seat is located in front of the rear crossbeam of the passenger seat. The battery pack side impact protection frame can effectively transmit and decompose the side impact load and protect the battery pack to meet the power safety requirements.
Description
technical field [0001] The invention belongs to the technical field of automobile bodies, in particular to a battery pack side impact protection frame and an automobile. Background technique [0002] The crash safety performance of automobiles is one of the core technologies in vehicle development and design. Among them, the design of the crash safety deformation structure of the body platform is the basis for improving the crash safety performance of the vehicle. With the popularization of automobiles and the development of technology, more and more attention has been paid to the collision safety of automobiles. In recent years, my country's relevant departments have continuously supplemented and improved some test conditions for vehicle crash safety performance in the relevant collision regulations (CNCAP) and evaluation specifications, and have higher and higher requirements for vehicle crash safety. In the traditional fuel body platform, the body collision force transm...
