The invention relates to the technical field of new energy automobile battery pack side collision protection, in particular to a new energy automobile structural part which is low in cost, high in cruising ability and high in side collision safety. Comprising a battery tray, a frame beam, a supporting cross beam, a doorsill inner plate and a doorsill outer plate which are all made of steel materials. The frame beams are fixedly connected to a vehicle body, located on the two sides of the battery tray and connected with the battery tray, and the supporting cross beams are fixedly connected to the frame beams. The doorsill inner plate is connected with the doorsill outer plate, a closed box-shaped piece is formed between the doorsill inner plate and the doorsill outer plate, more than three M-shaped structure reinforcing pieces are evenly distributed between the doorsill inner plate and the doorsill outer plate, and the M-shaped structure reinforcing pieces are made of ultrahigh-strength steel. The structure is simple and the manufacturing cost is low; the light weight is realized, and the cruising ability and the side collision safety are improved.
