Background
At present, the state advocates and promotes the development of new energy industry, wherein new energy automobile becomes an important direction for the development of new energy automobile industry. The electric automobile is a new energy automobile which takes a vehicle-mounted power supply as power and drives wheels to run by using a motor, and has small influence on the environment. The vehicle-mounted power supply is a battery, and the safety of the battery is particularly important.
CN 203472502U provides an electric automobile power battery box of integrated design, and the installation roof beam on automobile body floor designs into the frame-type fixed beam that can match the limit frame installation of tray under the power battery, and the flange face of frame-type fixed beam and limit frame passes through the bolt lug connection. In order to adapt to the arrangement of the battery module corresponding to the position of the rear seat of the vehicle higher than the position of the front seat, the section of the automobile floor within the range of the frame-type fixed beam is stepped. In order to realize stable connection of the battery pack and the vehicle body, the battery box of the electric vehicle is provided with an excessively complex connecting structure and connecting pieces; or the overall connecting strength is not enough due to the externally attached lifting lugs; the connection mode between the parts is common welding, and the strength of the welding seam of the connection structure is not enough, so that the connection failure is easily caused.
Disclosure of Invention
The invention aims to solve the technical problem of overcoming the defects of the prior art and provides a new energy automobile battery box body structure which is simple in structure, light in weight, high in structural strength and reliable in connection with an automobile body.
The invention solves the technical problem by adopting the technical scheme that the new energy automobile battery box body structure comprises a bottom plate, side plates and a top plate. The integral frame is arranged on the outer edge of the side plate and is formed by mutually and fixedly connecting a transverse frame and a longitudinal frame; the cross section of the frame is formed into a rectangular structure, a supporting member is arranged in the middle of the rectangular structure, two ends of the supporting member are respectively connected to 2 corners of the rectangular structure, the rectangular structure is equally divided into 2 hollow triangular structures with the same size, and lifting lugs are arranged on the outer side of the whole frame.
Furthermore, the lifting lugs are of a structure like a Chinese character 'ri', are symmetrically arranged on the outer sides of the longitudinal frames, and the number of each side is more than or equal to 4.
Furthermore, horizontal frame is equipped with four, indulge the frame and be equipped with four, for Contraband type connection between horizontal frame and the total frame, the connected mode is the welding.
The invention has the following positive effects: the cross sections of the transverse frame and the longitudinal frame are in the shape of hollow triangles, so that the strength of the whole frame is improved, the battery box body is not easy to deform when a vehicle is collided, a good protection function is provided for batteries in the battery box, and the whole battery box body is light; the local structural strength at the lifting lug is improved.
