As shown in fig. 3-5, according to the utility model discloses crowded box of aluminium 1, including polylith crowded section bar 100, polylith crowded section bar 100 splices into the open box in top each other, and the interior border of top of box is equipped with the turn-ups 101 of outwards buckling after upwards extending, and turn-ups 101 has horizontal segment 1011 and vertical section 1012, has arranged a plurality of rivet nuts 200 along the length direction of crowded section bar 100 of aluminium on the horizontal segment 1011, and horizontal segment 1011 is suitable for the sealed connection upper cover (not shown), and the upper cover is injectd the first cavity A that is suitable for installing the battery with the box jointly.

That is, the box body comprises an aluminum extruded section side plate and an aluminum extruded section bottom plate; the flanging 101 is formed by bending the side wall of the aluminum extruded section side plate 100 outwards after extending upwards, and the arrangement of the flanging 101 transfers the sealing surface of the aluminum extruded box body 1 and the upper cover onto the flanging 101. Therefore, through the arrangement of the aluminum extrusion box body 1, one end of the rivet nut 200 is arranged on the sealing surface of the box body, and the other end is arranged outside the box body; when the rivet nut is processed badly, the air leakage or water leakage at the rivet nut 200 is directly led to the outside of the box body and can not be communicated with the inside of the box body, so that the air tightness of the box body is ensured, and the aluminum extruded box body meets the requirements of IP68 or IP 67.

With reference to fig. 5, optionally, the inside of the aluminum extruded profile 100 is hollow to form a second cavity B, and the second cavity B is adapted to communicate with the first cavity a. That is to say, through the setting of turn-ups 101 for when second cavity B link up with first cavity A, the airtight performance of the crowded box 1 of true aluminium also can not influenced by the bad department of rivet nut 200, guarantees the quality of crowded box 1 of aluminium.

Optionally, with reference to fig. 3 and 4, a plurality of blind rivet nuts 200 are arranged at intervals on the horizontal section 1011. Therefore, the connection reliability between the aluminum extrusion box body 1 and the upper cover can be better ensured.

Optionally, the edge of each aluminum extrusion 100 is welded to the edge of an adjacent aluminum extrusion 100. That is, the side edge of the side plate of the aluminum extruded section is welded with the side edge of the side plate of the adjacent aluminum extruded section, and the bottom edge of the side plate of the aluminum extruded section is welded with the edge of the bottom plate of the aluminum extruded section. Therefore, the processing and the manufacturing of the aluminum extrusion box body 1 are convenient.

Optionally, the flange 101 is integrally formed with the aluminum extrusion 100. The aluminum extrusion molding can be adopted, so that the aluminum extrusion box body 1 is convenient to process and manufacture.

Optionally, the flange 101 is formed by vertically extending the top inner periphery of the box body upwards and then bending outwards by 90 °. That is, the flange 101 and the top surface of the aluminum extruded section 100 form a groove; the corners in the groove are all right angles. Thereby, the flange 101 can be connected with the upper cover in a better sealing way.
