Detailed Description

The technical solution of the present invention will be described clearly and completely through the following detailed description.

The utility model discloses a waterproof automobile distribution box, its concrete structure is shown as figure 1: the box comprises a box body 1, a box cover 2 and an electric device 3 arranged in the box body 1, wherein the box body is structurally shown in figure 2: the box body 1 is the open-ended cavity cuboid in top, and the inboard of 1 each side of box body all upwards extends a closing plate 4, each closing plate 4 end to end, and 2 inboards of lid are hugged closely to this closing plate 4 when covering lid 2 for the clearance that electric part 3 and block terminal isolated outside avoids between box body 1 and the lid 2 damages components and parts that intakes. The thickness of closing plate 4 is less than the thickness of box body 1, and the sum of 2 thickness of back lid and 4 thickness of closing plate is hugged closely conveniently with 2 lateral walls of lid equals the 1 wall thickness of box body, and the outside upper end of 1 each side of box body all is equipped with first straight plate 5 and first flap 6 outward in proper order, and the opening direction of keeping away from box body 1 is to the direction of buckling of first flap 6, should set up and can further effectively avoid water and other liquid to get into the block terminal and cause the incident.

The utility model discloses a lid 2 is below open-ended cavity cuboid, and its concrete structure is shown in fig. 3: the cross section of the box cover 2 is the same as that of the box body 1, so that the box cover 2 and the box body 1 are matched to complete the structural assembly of the distribution box. The wall thickness of the box cover 2 is also smaller than that of the box body 1, the wall thickness of the box body 1 is equal to the sum of the wall thickness of the box cover 2 and the wall thickness of the sealing plate 4, and the sealing plate 4 is tightly attached to the inner side surface of the box cover 2, so that the water inlet caused by a gap between the box cover 2 and the box body 1 is avoided in an isolated mode. Each side lower extreme of lid 2 all is equipped with second straight board 7 and second folded plate 8 in proper order, and the direction of buckling of second folded plate 8 is the same with the direction of buckling of first folded plate 6, and the width of second folded plate 8 is wider than the width of first folded plate 6 moreover, makes things convenient for second folded plate 8 and the laminating of first folded plate 6, passes through screw 9 fixed first straight board 5 and the straight board 6 of second at four angles of box body, and its concrete structure is as shown in fig. 4.

After the electric device 3 is arranged in the box body 1 of the distribution box, the box cover 2 is covered from the upper part to the lower part when the box cover 2 is covered, and after the box cover 2 is covered, the second folding plate 8 is attached to the first folding plate 6; a sealing gasket 10 is further arranged between the first straight plate 5 and the second straight plate 7, the first straight plate 5 and the second straight plate 7 are fixed at four corners of the distribution box through screws 9 respectively, so that the second straight plate 7 compresses the sealing gasket 10 to ensure the sealing performance of the distribution box, and the specific structure of the sealing gasket is shown in fig. 5. The waterproof function is further improved in the laminating setting of first folded plate 6 and second folded plate 8, the setting that is equipped with sealed pad 10 between first straight board 5 and the straight board 7 of second, thereby effectively avoid water or other liquid to get into in the high-voltage distribution box and damage components and parts, cause the incident.
