The invention discloses a metal and composite material combined battery box in the technical field of automobile parts. The battery box is composed of a high-strength metal frame, an upper shell madeof a composite material, a middle shell made of a composite material, a lower shell made of a composite material, a sealing rubber layer and a sealing rubber strip. According to the structural characteristics and technical requirements of the battery box, different materials are applied to different positions of the battery box, and the advantages of the materials are brought into full play, so the production cost is reduced, the rigidity requirement of the battery box is met, meanwhile, the frame weight is reduced to the maximum extent, the local stress is dispersed, and the connection reliability is improved.

    本发明公开了汽车零部件技术领域的一种金属与复合材料结合的电池箱,包括金属和复合材料结合的电池箱,所述电池箱由高强度金属的框架、复合材料的上壳体、复合材料的中间壳体、复合材料的下壳体、密封胶层和密封胶条这六个部件组成,根据电池箱的结构特点和技术要求,在电池箱不同位置应用了不同的材料,充分发挥各自材料发优点,降低生产成本,在满足电池箱刚度要求的同时最大限度的降低了框架重量,分散了局部应力,提高了连接可靠性。
