At the same time, in order to improve the assembly efficiency, reduce the number of battery packs, the electric quantity of single energy storage battery pack is also increasing, which leads to the increasing weight and size of energy storage battery pack. At present, the depth size of 104 strings of long battery pack has exceeded 2 meters. Since the depth is too large, the rear part of battery pack is not easy to fix.

[0003] The current solution is to fix the front part of battery pack by bolt and nut, and then increase limiting structure on both sides of battery pack. As shown in the following figure, limiting structure is added at the fixing bracket on both sides of battery pack (limiting structure is welded to battery pack fixing bracket), 4-5mm gap is left between limiting structure and hoisting bracket on both sides of battery pack, and 2mm foam is pasted below the limiting structure. During transportation, hoisting bracket on both sides of battery pack first contacts foam for shock absorption, and then the amplitude is limited by limiting bracket.

It should be understood that those skilled in the art can modify the utility model described herein while still achieving the advantageous effects of this utility model. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit this utility model.

[0031] The present invention will be described more specifically by way of example in the following paragraphs with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description and claims. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0032] like Figures 1 to 5 As shown in the figure, this utility model embodiment proposes an energy storage battery pack fixing structure, including a fixing frame 1, a support bracket 2, and a pressure plate structure.

[0033] Specifically, there are two fixing frames 1, and the two fixing frames 1 are arranged in parallel.

[0034] The support bracket 2 is provided in multiple pairs, and each pair of support brackets 2 is fixedly mounted on two fixed frames 1 respectively. The support bracket 2 is used to support and fix the end of the battery pack.

[0035] The pressing plate structure is rotatably mounted at one end on the support bracket 2 and detachably mounted at the other end on the support bracket 2, and is used for vertically pressing and fixing the battery pack.

[0036] In this embodiment, when the battery pack 13 needs to be fixed, the battery pack 13 is placed on the support bracket 2, and the end of the battery pack 13 is fixed on the support bracket 2. Then the pressing plate structure is rotated so that it presses against the edge of the battery pack 13, and finally the end of the pressing plate structure away from the rotating connection is fixed on the support bracket 2. At this time, the pressing plate structure fixes the battery pack 13 in the vertical direction, effectively preventing the battery pack 13 from vibrating up and down in the vertical direction, avoiding the loosening or disconnection of internal components, copper bars and aluminum bar connectors of the battery pack, and ensuring the safety of the battery pack transportation.

[0037] Further, the pressing plate structure includes a hinge 3, a pressing plate 4 and a pressing block 5.

[0038] Specifically, one end of the pressing plate 4 is rotatably mounted on the support bracket 2 through the hinge 3, and the other end of the pressing plate 4 is detachably mounted on the support bracket 2.

[0039] The pressing block 5 is fixedly arranged on the pressing plate 4, and when the pressing plate 4 is rotated to a horizontal state, the bottom surface of the pressing block 5 abuts against the upper surface of the edge of the battery pack 13.

[0040] In this embodiment, after the battery pack 13 is placed on the support bracket 2, the pressing plate 4 is rotated around the hinge 3 so that the pressing block 5 on the bottom surface of the pressing plate 4 is in close contact with the edge of the battery pack 13, and finally the end of the pressing plate 4 away from the hinge 3 is fixed to the support bracket 2. At this time, the pressing block 5 presses and fixes the edge of the battery pack 13, effectively reducing the vibration of the battery pack 13 in the vertical direction, thereby improving the safety of the battery pack 13 transportation.

[0041] In a specific embodiment, a fixing hole 6 is formed at the end of the pressing plate 4 away from the hinge 3. When fixing the end of the pressing plate 4 away from the hinge 3, after the pressing plate 4 is pressed against the support bracket 2, a bolt is used to pass through the fixing hole 6 and is screwed to the support bracket 2, thereby fixing the end of the pressing plate 4.

[0042] In addition, in order to ensure that the pressing block 5 can well fix the battery pack 13, a battery pack limiting support 7 is arranged in abutment with the bottom surface of the pressing block 5, the battery pack limiting support 7 is fixedly arranged on the edge of the battery pack 13, and a limiting groove 14 matched with the pressing block 5 is arranged on the battery pack limiting support 7.

[0043] When the pressing plate 4 is fixed on the support bracket 2, the lower pressing block 5 enters into the limiting groove 14, and the battery pack 13 is fixed by the battery pack limiting support 7, so that the vibration of the battery pack 13 in the vertical direction is effectively reduced, and the safety of the battery pack 13 in the transportation process is improved.

[0044] Further, the support bracket 2 comprises an upper support part 8, a connecting part 10 and a lower support part 9.

[0045] Specifically, the upper support part 8 is arranged in parallel with the lower support part 9, and the upper support part 8 and the lower support part 9 are fixedly connected through the connecting part 10; and the upper support part 8 is provided with a fastening hole for mounting the pressing plate structure at the end.

[0046] The width of the upper support part 8 is smaller than that of the lower support part 9, and the battery pack limiting support 7 is exposed outside the upper support part 8.

[0047] In an embodiment, two support fixing feet 11 are fixedly arranged on the lower support part 9, and the two support fixing feet 11 are arranged at two ends of the lower support part 9; the support fixing feet 11 are located between the upper support part 8 and the lower support part 9, and the support fixing feet 11 are provided with threaded holes 12 for fixing the battery pack.

[0048] When the battery pack 13 needs to be fixed, the edge of the battery pack 13 is arranged on the support fixing feet 11, and the edge of the battery pack 13 is fixed in the threaded holes 12 by using bolts; then the pressing plate 4 is rotated, so that the lower pressing block 5 on the pressing plate 4 passes through the upper support part 8 and presses and fixes the battery pack limiting support 7; finally, the pressing plate 4 is fixed in the fastening hole by using bolts. When the pressing plate structure is rotated to the horizontal state (i.e., when the pressing plate structure is fixed), the pressing plate structure is attached to the upper support part 8, and the pressing plate structure presses and fixes the battery pack. That is, the lower pressing block 5 can press and fix the middle part of the edge of the battery pack 13, solves the problem that the battery pack 13 is not convenient to fix due to the small gap between the fixing feet 1 and the battery pack 13, effectively reduces the vibration of the battery pack 13 in the vertical direction, and thus ensures the safety of the battery pack transportation.
