[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] Please also refer to Figures 1 to 4 The integrated energy storage cabinet combining structure provided by the present invention is now described. The integrated energy storage cabinet combining structure comprises: a first cabinet body 1 and a second cabinet body 2 adjacent to each other; the first cabinet body 1 is provided with a first combining member 101; a first guide portion 102 is provided at the top of one end of the first combining member 101 located outside the first cabinet body 1; a first guide slope 103 is provided on the side of the first guide portion 102 proximate to the first cabinet body 1; a second combining member 201 is provided on the second cabinet body 2; the second combining member 201 is located above the first combining member 101; and a second guide slope 202 is provided at the bottom of the second combining member 201 to slide with the first guide slope 103.

[0026] This embodiment provides an integrated energy storage cabinet combining structure. Compared with the prior art, the first combining member 101 is installed on the first cabinet body 1, the first guide portion 102 is located on the outside of the first combining member 101, and the first guide slope 103 is located on the side of the first guide portion 102 close to the first cabinet body 1; the second combining member 201 is installed on the second cabinet body 2, the second combining member 201 is located above the first combining member 101, and the second guide slope 202 is located at the bottom of the second combining member 201 and slidably engages with the first guide slope 103. When merging two energy storage cabinets, the first cabinet body 1 is first fixed to the installation position, and then the second cabinet body 2 is hoisted to one side of the first cabinet body 1. At this time, there will be a certain gap between the first cabinet body 1 and the second cabinet body 2. During the descent of the second cabinet body 2, the second guide inclined surface 202 will contact and slide relative to the first guide inclined surface 103. Therefore, the second cabinet body 2 will approach the side of the first cabinet body 1 under the action of the first guide part 102, and finally the second cabinet body 2 will be completely fitted with the first cabinet body 1, thereby reducing the footprint of the integrated energy storage cabinet.

[0027] In this embodiment, the first cabinet unit 101 and the second cabinet unit 201 only serve to guide and position the second cabinet 2. The first cabinet 1 and the second cabinet 2 must also be secured to their mounting locations using fasteners. The first guide portion 102 and the second cabinet unit 201 are rectangular trapezoids, and the first guide slope 103 and the second guide slope 202 are the slopes of the rectangular trapezoid. The first guide portion 102 and the first cabinet unit 101 are integrally formed.

[0028] In some embodiments, see Figure 1 、 Figure 2 and Figure 5 The bottoms of the first cabinet 1 and the second cabinet 2 are respectively provided with first supporting legs 104 and second supporting legs 203. The first cabinet merging member 101 is mounted on the first supporting legs 104, and the second cabinet merging member 201 is mounted on the second supporting legs 203. In this embodiment, the first supporting legs 104 are mounted on the front and rear sides of the bottom of the first cabinet 1, and the second supporting legs 203 are mounted on the front and rear sides of the bottom of the second cabinet 2. Therefore, the first cabinet merging member 101 is located at the front and rear bottoms of the first cabinet 1, and the second cabinet merging member 201 is located at the front and rear bottoms of the second cabinet 2.

[0029] In some embodiments, see Figure 2 The first cabinet combining member 101 is located inside the first support leg 104, and the second cabinet combining member 201 is located inside the second support leg 203. In this embodiment, the first cabinet combining member 101 is installed inside the first support leg 104, and the second cabinet combining member 201 is installed inside the second support leg 203. Therefore, the first cabinet combining member 101 is hidden inside the first cabinet body 1, and the second cabinet combining member 201 is hidden inside the second cabinet body 2, which improves the aesthetics of the integrated energy storage cabinet.

[0030] In some embodiments, see Figure 2 , the first cabinet combining part 101 is fixedly connected to the first support leg 104 by fasteners. In this embodiment, the first cabinet combining part 101 and the first support leg 104 are separate structures, which facilitates the disassembly and assembly of the first cabinet combining part 101. Since the second cabinet combining part 201 is located above the first cabinet combining part 101, if the second cabinet body 2 is disassembled first, the second cabinet body 2 can be directly hoisted. However, if the first cabinet body 1 is disassembled first, the first cabinet combining part 101 needs to be disassembled before the first cabinet body 1 can be hoisted. The first cabinet combining part 101 is fixed to the first support leg 104 by fasteners, which are screws or bolts.

[0031] In some embodiments, see Figure 2 and Figure 4 The second cabinet merging member 201 is connected to the second support leg 203 by welding. In this embodiment, the second cabinet merging member 201 is fixed to the second support leg 203 by welding, which ensures the connection strength between the second cabinet merging member 201 and the second support leg 203.

[0032] In some embodiments, see Figure 3 A connecting plate 3 is installed between the first cabinet 1 and the second cabinet 2. In this embodiment, the connecting plate 3 is a rectangular plate located near the top of the first cabinet 1 and the second cabinet 2. The connecting plate 3 is connected to the first cabinet 1 and the second cabinet 2 with screws, thereby improving the stability between the first cabinet 1 and the second cabinet 2.

[0033] In some embodiments, see Figure 1 and Figure 5 The connecting plate 3 is located at the front and rear sides of the first cabinet 1 and the second cabinet 2. In this embodiment, the sides of the first cabinet 1 and the second cabinet 2 are attached to each other, and the front and rear sides are fixed by the connecting plate 3, which prevents the first cabinet 1 and the second cabinet 2 from shaking.

[0034] In some embodiments, see Figure 6 and Figure 7 A sealing strip 4 is provided on the mating surface of the first cabinet 1 and the second cabinet 2. In this embodiment, the sealing strip 4 is fixed to the mating surface of the first cabinet 1 and / or the second cabinet 2. The sealing strip 4 is an annular structure and is arranged along the outer circumference of the first cabinet 1 or the second cabinet 2. The sealing strip 4 is used to improve the sealing between the first cabinet 1 and the second cabinet 2, thereby preventing rainwater or dust from entering the gap between the first cabinet 1 and the second cabinet 2. In order to improve the protective effect, the gap between the two cabinets can also be glued.

[0035] In some embodiments, see Figure 1 and Figure 6 , the left and right sides of the first cabinet 1 and the second cabinet 2 can be removably installed with a sealing plate 5. In this embodiment, the electrical components inside the first cabinet 1 and the second cabinet 2 need to be connected through a copper busbar. Since the distance between the first cabinet 1 and the second cabinet 2 is shortened, the required length of the copper busbar is also shortened, thereby reducing the manufacturing cost. When the first cabinet 1 and the second cabinet 2 are in a non-combined state, the sealing plate 5 needs to be waterproofed. The side of the first cabinet 1 and the second cabinet 2 that needs to be connected to the copper busbar is the AC side. When the first cabinet 1 and the second cabinet 2 are integrated into a cabinet, the AC side sealing plate 5 of the first cabinet 1 and the second cabinet 2 is removed.

[0036] In some embodiments, see Figure 7 The sealing plate 5 is located inside the sealing strip 4. In this embodiment, since the sealing plate 5 is located inside the sealing strip 4, the sealing strip 4 can ensure the sealing of the sealing plate 5. The copper busbar will pass through the through hole after the sealing plate 5 is removed, thereby preventing the copper busbar from being contaminated by rain or dust.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
