[0030] In this solution, the second connecting component will be set up to fix the back panel 3 on the rear side of the cabinet frame 1 under the action of the driving mechanism, and during the action of the second connecting component, the first connecting component will cooperate with the second connecting component through the transmission structure, so that the side panel 2 is fixedly connected to the side wall of the cabinet frame 1. Compared with the traditional welding fixation, the present application adopts a mechanical matching method, which is not only simple to operate but also more convenient for people to assemble, and avoids the situation of cold welding that requires rework, thereby improving the efficiency of assembling the energy storage cabinet.

[0031] See also Figure 5 , Figure 6The first connecting component includes a No. 1 mounting block 4 arranged on the side panel 2 and a No. 1 limiting hole 401 opened on the No. 1 mounting block 4, and a side panel mounting hole 101 for inserting the No. 1 mounting block 4 is opened on the cabinet frame 1.

[0032] In this embodiment, the first mounting block 4 is inserted into the side panel mounting hole 101, so that the side panel 2 cannot move vertically relative to the cabinet frame 1; The No. 1 limiting hole 401 is used to cooperate with the No. 1 clamping column 8 so that the side plate 2 cannot move horizontally.

[0033] See also Figure 5 , Figure 6 , Fig.10 The first connecting assembly also includes a No. 1 bidirectional screw rod 6 and a No. 1 slide groove 5 vertically arranged on the cabinet frame 1, the No. 1 bidirectional screw rod 6 is rotatably arranged inside the No. 1 slide groove 5, and a No. 1 slider 7 is slidably arranged in the No. 1 slide groove 5, and the No. 1 slider 7 and the No. 1 bidirectional screw rod 6 are threadedly matched with each other; The first slider 7 is provided with a first clamping column 8 matched with the first limiting hole 401 .

[0034] In this embodiment, since the No. 1 slider 7 is slidably set in the No. 1 slide groove 5, and the No. 1 slider 7 and the No. 1 bidirectional screw rod 6 are threadedly matched with each other, when the No. 1 bidirectional screw rod 6 rotates, the No. 1 slider 7 will drive the No. 1 clamping column 8 to approach the No. 1 mounting block 4, and make one end of the No. 1 clamping column 8 pass through the No. 1 limiting hole 401, thereby locking the No. 1 mounting block 4 in the side panel mounting hole 101.

[0036] In this embodiment, the connection block 9 is inserted into the back panel mounting hole 102 so that the back panel 3 and the cabinet frame 1 are positioned and fitted. At this time, the connection between the back panel 3 and the cabinet frame 1 is not firm.

[0037] See also Figure 7 , Figure 8 , Fig.10 , the second connecting assembly further includes a second mounting block 10 disposed on the back plate 3 and a second limiting hole 1001 opened on the second mounting block 10; A second slide groove 11 is horizontally provided on the cabinet frame 1, a second bidirectional screw rod 12 is rotatably provided in the second slide groove 11, a second slider 13 is slidably provided in the second slide groove 11, the second slider 13 and the second bidirectional screw rod 12 are threadedly matched with each other, and one end of the second slider 13 extends to the outside of the second slide groove 11; A second clamping column 14 is horizontally disposed at one end of the second sliding block 13 , and the second clamping column 14 is adapted to the second limiting hole 1001 .

[0038] In this embodiment, since the No. 2 slider 13 is slidably set in the No. 2 slide groove 11, and the No. 2 slider 13 and the No. 2 bidirectional screw rod 12 are threadedly matched with each other, when the No. 2 bidirectional screw rod 12 rotates, the No. 2 slider 13 will drive the No. 2 clamping column 14 to approach the No. 2 mounting block 10, and make one end of the No. 2 clamping column 14 pass through the No. 2 limiting hole 1001, thereby realizing the locking of the No. 2 mounting block 10, that is, the connecting block 9 is firmly locked inside the back plate mounting hole 102.

[0039] See also Figure 6 , Fig.10 The transmission structure includes a fixed frame 15 and a No. 3 slide 16 provided on the cabinet frame 1, wherein the No. 3 slide 16 is respectively connected with the No. 1 slide 5 and the No. 2 slide 11 and are perpendicular to each other, and the fixed frame 15 is fixedly installed in the No. 3 slide 16; A rotating rod 17 is horizontally rotatably arranged on the fixing frame 15, a first bevel gear 18 is arranged at one end of the rotating rod 17, and a third bevel gear 20 is arranged at the other end of the rotating rod 17; The outer wall of the second bidirectional screw 12 is provided with a second bevel gear 19 meshing with the first bevel gear 18 , and the outer wall of the first bidirectional screw 6 is provided with a fourth bevel gear 21 meshing with the third bevel gear 20 .

[0040] In this embodiment, since the first bevel gear 18 and the second bevel gear 19 are meshed with each other, and the third bevel gear 20 and the fourth bevel gear 21 are meshed with each other, when the second bevel gear 19 follows the second bidirectional screw 12 to rotate, the first bevel gear 18 will drive the rotating rod 17 to rotate. At the same time, the third bevel gear 20 will follow the rotating rod 17 to drive the fourth bevel gear 21 to rotate, so that the first bidirectional screw 6 follows the fourth bevel gear 21 to rotate.

[0041] See also Figure 6 , Fig.10 The driving mechanism includes a worm 22 rotatably arranged on the cabinet frame 1 and a worm wheel 23 arranged on the second bidirectional screw 12 , the worm 22 and the worm wheel 23 are meshed with each other, and a knob 24 is arranged at one end of the worm 22 .

[0042] In this embodiment, an external force is used to drive the worm 22 to rotate through the knob 24. Since the worm 22 and the worm wheel 23 are meshed with each other, the worm wheel 23 drives the second bidirectional screw 12 to rotate. Because the worm 22 and the worm wheel 23 have a self-locking function, the worm wheel 23 will keep the second bidirectional screw 12 stationary at all times when no external force is applied.
