An automotive battery protection structure

The present invention discloses an automobile battery protection structure comprises: the passage, located in the left and right channels and two protection assembly disposed symmetrically, each protection component comprising a door threshold, the seat assembly beams, the floor panel, stringers , one end of the seat assembly and the upper beams connected sill, an upper end connected to the other end of the channel, one end of the floor panel and the lower threshold, and the other end connected to the lower end of the channel, the side sill is provided on the lower surface of the floor panel, and longitudinal stringers through the body, the battery pack is disposed below the car in the channel. The present invention is respectively connected to the seat rail assembly, the threshold between the floor panel and by the channel, are generated by impact of the collision is transmitted to the decomposition of the seat rail assembly and the floor panel and by the threshold, greatly reducing the risk of deformation of the floor panel; reinforcement action threshold, the seat rail assembly, the floor panel, the channels forming the frame structure, and the longitudinal beam, so that the overall structural rigidity to enhance protection.
