Detailed Description

The following will further explain the specific implementation method of the present invention with reference to the drawings.

Fig. 1 is a schematic perspective view of a power module packaging box with shock-proof and bending-resistant functions. The packing box comprises an outer packing box and an anti-static protective layer arranged in the outer packing box. The outer packing box comprises an inner box body 2 and a top cover 1, wherein the size of the inner box body is 205mm multiplied by 155mm multiplied by 285mm, and the size of the outer packing box body is 215mm multiplied by 160mm multiplied by 365mm. The inner and outer edges are 2.4mm. The outer side of the long side surface of the box body 2 in the outer packaging box and the inner side of the bending surface of the top cover are both provided with embedded magnetic cores 3.

The bottom material of the outer packing box is rubber board paper, the whole surface of the outer packing box is wrapped by green waterproof paper, and the material of the anti-static protective layer is black anti-static sponge.

Fig. 2 and 8 are schematic perspective views of the bottom leg protection layer 4 and the top power module cover protection layer 6 of the anti-static protection layer, respectively. The dimensions of length, width and height are 200mm, 150mm and 10mm. The top layer power module apron 6 lower right corner has convex incision, conveniently takes.
