Detailed Description
(example 1)
Referring to fig. 1 to 4, the battery box top-mounted ventilation hood of the present embodiment includes an inner hood 1 and an outer hood 2; the bottom of the inner cover 1 is provided with a vent hole 3; the outer cover 2 is covered on the inner cover 1, and an air outlet channel 4 with an air outlet facing downwards is formed between the outer cover 2 and the inner cover 1.
Further, the inner cover 1 comprises a mounting part 1-1, a first vertical part 1-2 extending upwards along the edge of the mounting part 1-1 and a plurality of first transverse parts 1-3 extending outwards from the top of the first vertical part 1-2, wherein the first vertical part 1-2 is preferably arranged perpendicular to the mounting part 1-1, and the first transverse parts 1-3 are preferably arranged perpendicular to the first vertical part 1-2; the vent hole 3 is arranged in the center of the mounting part 1-1; the mounting part 1-1 is used for being fixedly connected with the top of the battery box, a plurality of connecting holes are uniformly distributed in the mounting part 1-1, and the mounting part 1-1 penetrates through the connecting holes through screws to be fixedly connected with the top of the battery box.
Further, the housing 2 comprises a top cover 2-1; the top cover 2-1 is fixed above the first transverse part 1-3; the edge of the top cover 2-1 is provided with a second vertical part 2-2 extending downwards, and the second vertical part 2-2 is preferably perpendicular to the top cover 2-1; a second transverse portion 2-3 extends in the bottom box of the second vertical portion 2-2, the second transverse portion 2-3 preferably being in a perpendicular society with the second vertical portion 2-2, and the second transverse portion 2-3 extending below the first transverse portion 1-3.
