The above-mentioned cylindrical cell type energy storage device of the present invention can be applied to an energy storage device made of a cylindrical cell type, such as an outdoor power supply, etc., and the following description will be made by specific embodiments:
Referring to fig. 1 to 9, a first embodiment of the present invention is as follows:
The utility model provides a cylinder electricity core formula energy memory, includes electric core subassembly 1, upper cover plate 2, lower apron 3, preceding apron 4, back shroud 5, side cap 6, side installing support 7 and last installing support 8, and the relation of connection between above-mentioned each part specifically states as follows:
First, as shown in fig. 2, the cell assembly 1 includes an upper harness isolation plate 11, a lower harness isolation plate 12, a cylindrical cell 13, and an aluminum conductive sheet 14; a plurality of accommodating grooves 111 matched with the cylindrical battery cells 13 are formed in the opposite surfaces of the upper wire harness isolation plate 11 and the lower wire harness isolation plate 12, and two ends of the cylindrical battery cells 13 are fixed in the accommodating grooves 111 of the upper wire harness isolation plate 11 and the lower wire harness isolation plate 12; corresponding peripheral structures 112 are arranged on the front side and the rear side of the upper wire harness isolation plate 11 and the lower wire harness isolation plate 12, and the surfaces, far away from the cylindrical battery cells 13, of the upper wire harness isolation plate 11 and the lower wire harness isolation plate 12 and the surfaces, far away from the cylindrical battery cells 13, of the peripheral structures 112 are supporting surface structures 113; thus, in welding the conductive aluminum sheet 14, no matter the single-sided welding is vertically placed, or the double-sided simultaneous welding is laterally placed, no tooling jig is required to be designed, thereby reducing the manufacturing cost.
Next, as shown in fig. 4, the lower harness isolation board 12 of the battery cell assembly 1 is provided with a positioning bump 121 on only one side, and the lower cover plate 3 is provided with a positioning notch at a corresponding position to form a positioning foolproof structure, so that the battery cell assembly 1 and the lower cover plate 3 are aligned through the positioning bump 121 and the positioning notch, and then locked through a preset corresponding hole site to realize alignment locking of the battery cell assembly 1 and the lower cover plate 3.
Next, as shown in fig. 5 and 6, the upper harness isolation plate 11 and the lower harness isolation plate 12 of the battery module 1 each include a plurality of screw hole posts 122 on the sides respectively adjacent to the side mounting brackets 7, and the side of a portion of the screw hole posts 122 on each side is provided with positioning posts 123 protruding from the screw hole posts 122, and the side mounting brackets 7 and 8 are provided with through holes 71 at positions corresponding to the screw hole posts 122 and the positioning posts 123 to form a positioning fool-proof structure. In this embodiment, as shown in fig. 5, two screw hole columns 122 are disposed on one side surface of the upper wire harness isolation board 11 and the lower wire harness isolation board 12 of the battery module 1, wherein a positioning column 123 protruding from the screw hole column 122 is disposed on one side of one screw hole column 122, that is, four screw hole columns 122 on the same side, wherein two screw hole columns with the positioning column 123 are disposed, the four screw hole columns 122 and the corresponding positioning column 123 are not symmetrical about the center as a whole, therefore, when the placement directions of the two columns are inaccurate, the side mounting bracket 7 does not have a corresponding through hole 71 for the positioning column 123 to pass through, and thus, the function of positioning fool-proof is realized. Therefore, after the two side mounting brackets 7 are vertically placed, the two side mounting brackets 7 are horizontally mounted on the battery cell assembly 1 according to the corresponding positions of the screw hole columns 122, the positioning columns 123 and the through holes 71, and the two side mounting brackets 7 are locked with the two sides of the battery cell assembly 1 through the first locking points 7-1 formed by the screw hole columns 122 on the sides of the battery cell assembly 1.
Then, as shown in fig. 5 and 6, the upper harness isolation plate 11 of the battery module 1 includes a plurality of screw hole columns 122, and a positioning column 123 protruding from the screw hole columns 122 is provided at a side of a portion of the screw hole columns 122, and the upper mounting bracket 8 is provided with a through hole 71 at a position corresponding to the screw hole columns 122 and the positioning column 123 to form a positioning fool-proof structure. In this embodiment, as shown in fig. 5, four screw hole columns 122 are formed at the middle positions of two sides of the upper harness isolation plate 11, wherein the side edges of three screw hole columns 122 are provided with positioning columns 123 protruding from the screw hole columns 122, and when the placement directions of the two columns are inaccurate, the upper mounting bracket 8 does not have corresponding through holes 71 for the positioning columns 123 to pass through, so that the foolproof positioning effect is realized. Thus, after the upper mounting bracket 8 is horizontally placed, the upper wire harness isolation plate 11 of the battery module 1 is vertically mounted according to the corresponding positions of the screw hole column 122, the positioning column 123 and the through hole 71, and the second locking point 8-1 is formed through the screw hole column 122 on the upper wire harness isolation plate 11 to lock the battery module 1 and the upper mounting bracket 8.
Simultaneously, the third locking point 8-7 formed by the screw hole column 122 above the side mounting bracket 7 locks the side mounting bracket 7 and the upper mounting bracket 8.
