Fig. 1, Fig. 2 and Fig. 3 show a specific embodiment of the utility model this kind of electric automobile battery box, and this cell box comprises casing 1 and case lid 2.Described casing 1 is the box-structure of open topped, it is made up of box bottom and some pieces of box sides being vertically around in around this box bottom, and being fixedly installed outside fix limit 1a on the box side outer wall of this casing 1, the inside of this casing 1 is fixedly installed inner position limit 1b. Such as Fig. 2, described case lid 2 is the uncovered box-structure in bottom, and it is made up of case lid top board and some blocks of case lid side plates being vertically around in around this case lid top board, and turns up and arrange thus be formed with location flange 2a in uncovered limit, the bottom of this case lid 2. Such as Fig. 3, described case lid 2 is buckled in casing 1 top and covers on the open topped outer (case lid side plate is positioned at outside box side) of casing 1, and described location flange 2a and outside fix limit 1a is bolted to connection, and it is folded with the first sealed strip (not shown) between; The case lid top board of described case lid 2 is pressed on described inner position limit 1b, and is folded with the 2nd sealed strip (not shown) between.
Therefore, this kind of electric automobile battery box in the present embodiment, it is provided with two seals bar between its casing 1 and case lid 2, and an outer layout in this two seals bar one, case lid 2 is covered on outside casing 1 simultaneously, and case lid is overlayed on the uncovered opening's edge place of casing by nontraditional technology, greatly strengthen electric automobile battery box stopping property.
When assembling, generally described first sealed strip is fixed in advance on described outside fix limit 1a, described 2nd sealed strip is fixed on described inner position limit 1b in advance, again case lid 2 and casing 1 are linked together afterwards.
With reference to, shown in Fig. 1, in this example, described outside fix limit 1a is closed ring structure (and non-circular), and it is around in outside described box side. With reference to, shown in Fig. 2, answering with the shape of described outside fix limit 1a, described location flange 2a is also closed ring structure (and non-circular), and it is around in the uncovered opening's edge place, bottom of described case lid 2. So, location flange 2a is connected cooperation and between after sandwiched first sealed strip, thus forms a completely closed annular sealing strip with outside fix limit 1a, effectively prevents external substance from being entered in case by the first sealed strip.
As shown in figures 1 and 3, in order to enable this cell box be installed to very easily on automobile frame, this example is fixedly installed multiple Connection Block 3 on the box side outer wall of described casing 1, described Connection Block 3 is offered for wearing the connection hole 3a of bolt to be connected on automobile frame by Connection Block. During practical application, the connection hole being directed at by the connection hole 3a on each Connection Block 3 on electric automobile frame, and after connecting and wearing bolt and nut locking in hole, just completes the installation of this cell box on automobile and fixes.
In this example, described casing 1, case lid 2 and Connection Block 3 are metal material, are generally steel or aluminium matter, and described Connection Block 3 is weldingly fixed on the outer wall of described casing 1.
Refer again to shown in Fig. 1 and Fig. 3, described Connection Block 3 have employed the extremely high structure of a kind of intensity, welding plate 31 that it is welded on described casing 1 outer wall by laminating, it is arranged vertically on this web plate left and right sides and be parallel to each other two pieces erect to side plate 32 and are connected horizontally on these two pieces and erect the horizontal top 33 to side plate top and form, described welding plate 31, erecting and be structure as a whole to side plate 32 and horizontal top 33, described connection hole 3a is opened in described horizontal top 33.
In the present embodiment, the structure of described casing 1 is as shown in Figure 1, it is made up of left half chests 11, right half chests 12 and the middle case 13 that is connected between described left half chests and right half chests, described left half chests 11 and right half chests 12 are rectangular configuration, and the length horizontal cross layout of left half chests 11, the length level of right half chests 12 is longitudinally arranged, left half chests 11 is arranged vertically with right half chests 12.Accordingly, as shown in Figure 2, the case lid top board of described case lid 2 is made up of left half top board 21, right half top board 22 and the middle top board 23 that is connected between described left half top board and right half top board, described left half top board 21 and right half top board 22 are rectangular configuration, and the length horizontal cross layout of left half top board 21, the length level of right half top board 22 is longitudinally arranged, left half top board 21 is arranged vertically with right half top board 22. Casing 1 and the structure of case lid 2 are so set, the components and parts such as battery can be made to arrange convenient at the subregion of casing 1, some components and parts can be avoided because of the too close of layout simultaneously to affect the job stability of power cell.
And, be provided with in described left half chests 11 five pieces be arranged in parallel thus the inner volume of this left half chests is separated into the left clapboard 4 of six separate cavities, be provided with in described right half chests 12 three pieces be arranged in parallel thus the inner volume of this right half chests is separated into the right clapboard 5 of four separate cavities, and described left clapboard 4 is also arranged in parallel with right clapboard 5. After adopting dividing plate that cabinets cavity is separated into multiple mutually isolated cavity opened so that the layout of the elements such as battery cell in casing 1 is convenient, more firmly.
In addition, in order to strengthen the structural strength of described case lid 2, this example is shaped with twenty-one provision stiffening web 2b spaced apart from each other in the case lid top board upper punch of this case lid, wherein, a longest stiffening web 2b horizontal cross layout and its length are across described left half top board 21, middle top board 23 and right half top board 22, one article of stiffening web 2b level of vice-minister's (namely the 2nd is long) is longitudinally arranged on described right half top board 22, that stiffening web 2b of the longest visible that stiffening web 2b and vice-minister is perpendicular, ten stiffening web 2b are also had to be distributed on described left half top board 21 radially, all the other nine stiffening web 2b are distributed on described right half top board 22 radially. this example is arranged in the manner described above ingenious for these stiffening webs 2b on the case lid top board of case lid 2, greatly strengthen case lid top board structural strength everywhere.
Above-mentioned twenty-one provision stiffening web 2b punching on case lid top board is formed, and stiffening web 2b is to lower convexity.
Certainly, the quantity of above-mentioned stiffening web 2b is not limited to twenty-one provision, it is also possible to is ten, 30, is generally more than ten.
Certainly, above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to allow people can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this. All equivalent transformations of doing according to the spirit of the utility model main technical schemes or modification, all should be encompassed within protection domain of the present utility model.
