[0021] Reference Figures 1-5This power supply box cover includes a cover body 1 integrally molded from BMC material. The cover body 1 includes a middle cover plate 11 and side cover plates 12 connected to its front and rear sides respectively. The middle cover plate 11 has a continuously bent shape, and an electrical cavity is formed between the middle cover plate 11 and the side cover plates 12 to accommodate circuit boards and power devices. The height of the electrical cavity decreases from the middle position to the left and right sides. The side wall of the cover body 1 is provided with circuit board lead ports 13 and power lead ports 14. The circuit board lead ports 13 and power lead ports 14 are located on the same side of the power box base 2 and are adjacent to each other. Compared with power boxes made of general plastic materials, the power box cover has better strength and rigidity, as well as better high temperature resistance, improving the durability and safety of the product. The shape of the middle cover plate 11 can improve the overall structural strength of the cover body 1 and also allow the electrical cavity to better accommodate the circuit boards and power devices that are higher in the middle.
[0022] Furthermore, the outer side of the middle cover plate 11 is provided with a relief recess 111 that corresponds to the shape of the external electrical equipment, and the inner side of the middle cover plate 11 protrudes towards the electrical cavity corresponding to the position of the relief recess 111. This can make the fit between the cover body 1 and the external electrical equipment higher, the installation structure more compact, and at the same time improve the structural strength of the cover body 1.
[0023] A BMC power box includes a power box base 2 and a cover body 1. The power box base 2 is integrally formed from BMC material. The cover body 1 and the power box base 2 are installed and fixed by a limiting mechanism. Compared with power boxes made of general plastic materials, the power box base 2 has better strength and rigidity, as well as better high temperature resistance, thus improving the durability and safety of the product.
[0024] Furthermore, the limiting mechanism includes a limiting protrusion 15 and a limiting concave step 21. The limiting protrusion 15 is disposed around the bottom of the cover body 1, and the limiting concave step 21 is disposed around the inner side of the opening of the power box base 2.
