Abstract
The invention relates to an aluminum alloy battery box. The aluminum alloy battery box comprises a battery box upper cover and a battery box bottom cover, wherein the battery box upper cover comprises a bottom wall, a plurality of side walls which extend from the bottom wall and surround the bottom wall and a storage cavity which is collectively formed by the bottom wall and the side walls, the battery box cover is in a trapezoid structure, and the aluminum alloy battery box is characterized in that a plurality of strip-shaped reinforcing ribs are distributed in the battery box bottom cover, the strip-shaped reinforcing ribs are connected with the bottom of the battery box in a riveting manner, a flaky reinforcing rib is also arranged between a projection of the side wall of the battery box lower cover and each side wall, every two flaky reinforcing ribs form a group to be arranged on the side wall, and a plurality of groups of flaky reinforcing ribs are arranged on the periphery of the side wall at intervals. The battery box bottom cover is provided with the reinforcing ribs, so that the strength of the battery box is guaranteed; the contact area between a battery and the battery box bottom cover is also reduced through the protruded reinforcing ribs on the bottom, the heat radiating effect is improved, the weight of the battery box adopting the material can be greatly reduced, and the manufacturing cost is also low.
Description
technical field:
The present invention relates to a kind of aluminum alloy battery.
background technology:
Battery case is for holding battery pack and the lead-in wire that is connected outside and battery.
On market, conventional battery case is rectangular frame structure, and frame, underframe use section bar welding, and build is large, and structural strength is low, and cost is high.
summary of the invention:
The object of this invention is to provide the Battery case of the metal material that a kind of intensity and rotproofness are high.
The technical solution adopted in the present invention is: a kind of aluminum alloy battery, it comprises battery case upper cover and battery case bottom, the host cavity jointly forming around some sidewalls of diapire with by diapire and sidewall that battery case upper cover comprises diapire, extends from diapire, battery case case lid is trapezium structure, it is characterized in that: have reinforcement in battery case bottom internal placement.
Further, described bar shaped reinforcement is connected with battery case bottom by riveted joint.
Further, between the place of suddenly extending of described battery case lower cover sidewall and sidewall, be provided with sheet reinforcement.
The beneficial effect that the present invention produces is: this battery case adopts aluminium alloy to make, by processing to ensure its intensity at the reinforcement of battery case bottom, the outstanding reinforcement in bottom has also reduced the contact area of battery and battery case bottom, when having increased radiating effect, adopt such material can greatly alleviate the weight of integral battery door case, be only 1/2nd of other metal materials, and intensity and rotproofness are higher than the casing of other metal materials; Its manufacturing cost is also quite cheap.
brief description of the drawings:
Fig. 1 is the reinforcement schematic diagram of aluminum alloy battery bottom;
Fig. 2 is structural representation of the present invention.
embodiment:
The present invention is described further by reference to the accompanying drawings in bottom surface.
As shown in Figure 2, a kind of aluminum alloy battery, comprises that battery case upper cover 2 and battery case bottom 3 are for placing batteries of electric automobile group, and whole casing is notch cuttype structure, is convenient to be placed on electric automobile inside, and agrees with other positions of electric automobile vehicle body.As can be seen from Figure 1, have bar shaped reinforcement 1 in the bottom inner side riveted joint of battery case, parallel bottom 3 inner sides that are placed on of polylith bar shaped reinforcement 1, have ensured battery case bulk strength.Bar shaped reinforcement body is trapezium structure, can reduce the contact area of battery and battery case bottom 3 with bottom 3 in conjunction with rear outstanding reinforcement, has strengthened performance of ventilating, increases radiating effect.
Sheet reinforcement 4 on aluminum alloy battery sidewall is for increasing the firm degree of extended protuberance and sidewall from sidewall, sheet reinforcement 4 is arranged on sidewall taking two as one group, many group sheet reinforcements 4 are placed along sidewall surrounding at certain intervals, upper cover 2 for better and battery case is fixing, and fixed form is for being used hexagon flange bolt to connect.
Finally explanation is, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, other amendments that those of ordinary skill in the art make technical scheme of the present invention or be equal to replacement, only otherwise depart from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of claim scope of the present invention.
Claims (3)
1. an aluminum alloy battery, it comprises battery case upper cover and battery case lower cover, the host cavity jointly forming around some sidewalls of diapire with by diapire and sidewall that battery case upper cover comprises diapire, extends from diapire, battery case upper cover is trapezium structure, it is characterized in that: the lower cover internal placement at battery case has bar shaped reinforcement.
2. a kind of aluminum alloy battery according to claim 1, is characterized in that: described bar shaped reinforcement is connected with battery case bottom by riveted joint.
