[0023] In order to make the person skilled in the art can better understand the utility model, the following combining with the drawings and example to the utility model technical scheme further explanation.

[0024] As Figure 1 、 Figure 2 、 Figure 3 The utility model discloses a PACK module star chain type connecting structure, including the multiple battery module 2 of horizontal array installation on base plate 1, in horizontal direction, install the first link lock catch 3 between the upper and lower two adjacent battery module 2 of side side, and the first link lock catch 3 is placed vertically;

[0025] In horizontal direction, install the second link lock catch 4 between the left and right two adjacent battery module 2 of side side, and the second link lock catch 4 is placed horizontally;

[0026] In the horizontal direction, the third link lock 5 is installed between the adjacent battery modules 2 in four directions on the side.

[0027] The first link lock 3 and the second link lock 4 are the same structure, and the first link lock 3 comprises a first rectangular plate 31, and the first rectangular plate 31 is provided with a first fixing hole 32 at both ends.

[0028] The third link lock 5 comprises a second rectangular plate 51, and the second rectangular plate 51 is provided with a second fixing hole 52 at the four corners.

[0029] In the embodiment, when the PACK module star chain connection structure is used, after the battery module 2 is installed, the first link lock 3 is used to connect the battery modules 2 at the outermost ends on the left and right sides, then the second link lock 4 is used to connect the battery modules 2 at the outermost ends on the upper and lower sides, and then the third link lock 5 is used to connect the ends of all the battery modules 2 in the inside, so as to form a star chain connection mode, which is called a star chain connection structure. The connection mode can effectively link all the originally isolated modules in the PACK package to form a stable whole, and can effectively prevent the impact force from the bottom and the side during hoisting and transportation.

[0030] Preferably, the first rectangular plate 31 and the second rectangular plate 51 are deburred by rounding, which can prevent scratching the user during installation and connection. Actually, the structure shape and processing measures of the first rectangular plate 31 and the second rectangular plate 51 can be considered according to the specific situation.

[0031] Preferably, the thickness of the first rectangular plate 31 and the second rectangular plate 51 is not less than two millimeters, which can ensure the connection and support strength. Actually, the thickness of the first rectangular plate 31 and the second rectangular plate 51 can be considered according to the specific situation.
