The battery case 10 includes an upper cover plate 11, a frame 12, and a first positioning lug 13, wherein the first positioning lug 13 is connected to the edge of the upper cover plate 11 in a reversible manner, and when the upper cover plate 11 covers an upper opening 110 of the frame 12, the first positioning lug 13 can be turned over to a side surface 111 of the frame 12, thereby limiting the position of the edge of the upper cover plate 11 relative to the side surface 111 of the frame 12, so as to position the upper cover plate 11 on the frame 12.

Further, a second positioning portion 112 may be disposed on the side surface 111 of the frame 12, and when the first positioning lug 13 is turned over to the side surface 111 of the frame 12, the first positioning lug 13 can cooperate with the second positioning portion 112 to limit the position of the first positioning lug 13 relative to the frame 12 by the second positioning portion 112, so as to further improve the accuracy of positioning the position of the upper cover plate 11 relative to the frame 12 by the first positioning lug 13, and reduce the probability of the first positioning lug 13 sliding along the side surface 111 of the frame 12.

It should be noted that, in this embodiment, the second positioning portion 112 is a positioning groove opened on the side surface 111 of the frame 12, and does not protrude from the side surface 111 of the frame 12, so as to facilitate design and manufacture, and the first positioning lug 13 can be turned over into the positioning groove, so that the position of the corresponding first positioning lug 13 is defined by the side wall of the positioning groove. In other embodiments, the second positioning portion 112 may also be a protrusion protruding from the side surface 111 of the frame 12, so that the first positioning lug 13 is positioned to be turned over to the side surface 111 of the frame 12 by the second positioning portion 112 penetrating into the first positioning lug 13.

Taking the first positioning lug 13 on the right side in fig. 2 as an example, one end of the corresponding first connecting portion 15 close to the upper cover plate 11 is tapered, and the width of the first connecting portion 15 in the first direction a is smaller than the width of one end of the first connecting portion 15 close to the first positioning lug 13 in the first direction a, and is also smaller than the width of the first positioning lug 13 in the first direction a, so that a narrower connection with the upper cover plate 11 is realized. In addition, in other embodiments, the first connecting portion 15 may have other shapes.

Further, the number of the first positioning lugs 13 may be multiple, and the multiple first positioning lugs 13 are distributed along the edge of the upper cover plate 11 to be turned over to the side surface 111 of the frame body 12 at the same time, so as to jointly define the position of the upper cover plate 11 relative to the frame body 12, and further improve the positioning accuracy.

It should be noted that, the first positioning lugs 13 are disposed on two edges corresponding to one corner 115 of the upper cover plate 11, and the two first positioning lugs 13 are disposed close to the corner 115, so that the position of the corner 115 relative to the frame 12 is defined by the two first positioning lugs 13 together, so that the corner 115 of the upper cover plate 11 and the frame 12 can be aligned more precisely.

Also, two first positioning lugs 13 may be provided on the upper cover plate 11 on both sides of each corner 115, and in the manner described above, so that the corners 115 of the upper cover plate can be aligned with the frame 12.

Furthermore, the battery case 10 may further include a lower cover plate 16 and a second positioning lug 17, the second positioning lug 17 may also be connected to the edge of the lower cover plate 16 in a reversible manner, and the second positioning lug 17 may be turned over to the side 111 of the frame body 12 when the lower cover plate 16 is placed on the lower opening 116 of the frame body 12, thereby defining the position of the lower cover plate 16 with respect to the frame body 12.

The number of the second positioning lugs 17 is also multiple, and the arrangement manner is similar to that of the first positioning lugs 13, and the side 111 of the frame 12 is further provided with a third positioning portion 113, and the third positioning portion 113 is also a positioning groove, which is similar to the second positioning portion 112, and is not repeated here.

The working principle of the battery case 10 provided by the embodiment of the utility model is as follows:

the battery case 10 includes an upper cover plate 11, a frame 12 and a first positioning lug 13, wherein the first positioning lug 13 is connected to the edge of the upper cover plate 11 in a reversible manner, and when the upper cover plate 11 covers an upper opening 110 of the frame 12, the first positioning lug 13 can be turned over to a side surface 111 of the frame 12, thereby limiting the position of the edge of the upper cover plate 11 relative to the side surface 111 of the frame 12, and achieving the purpose of positioning the upper cover plate 11 to the frame 12.
