Description

Technical field:

[0001] The invention relates to the field of automobiles (including electric automobiles, motor automobiles, and hybrid electric automobiles), in particular to automobiles with one-time molded plastic car shells. Background technique:

[0002] Chinese invention patent ZL01142849.X discloses a new type of plastic body structure, which is composed of body parts connected by a skeleton and an outer shell. The hollow sandwich member is formed by merging the sheets. There is sufficient space in the hollow sandwich member to contain the inner bracket, and the space of the sandwich member is filled with foam plastic, and then the overall shell is fixed and formed to form a body part. The disadvantages of this structure are: 1. Although the aluminum alloy inner bracket and foaming in the sandwich member can ensure the strength, it also increases the cost and production process; Molding is troublesome, and after the aluminum alloy inner bracket is assembled, the inn...
