[0049] As shown in Figure 2 , Figures 8 to 11 The frame 30 includes the bottom frame 330 and the top frame 310 arranged in parallel and the side frame 320 fixedly arranged between the top frame 310 and the bottom frame 330. The bottom frame 330, the top frame 310 and the side frame 320 each have an extension section 350 extending towards the side away from the cabinet door 20. The side of the extension section 350 away from the cabinet door 20 is connected with the turn-up structure 340.

[0050] The top frame 310, the side frame 320, the bottom frame 330 and the side frame 320 are sequentially connected in series to form the frame 30.

[0051] Specifically, the top frame 310, the side frame 320, the bottom frame 330 and the side frame 320 are sequentially welded in series, and the top frame 310, the side frame 320, the bottom frame 330 and the side frame 320 are each welded with the cabinet door 20 to achieve the installation and fixation of the frame 30 with the cabinet door 20.

[0052] In the embodiment, the bottom frame 330, the top frame 310 and the side frame 320 each further include a plate section for welding with the cabinet door 20. The plate section is connected with the side of the extension section 350 away from the turn-up structure 340. The end of the frame 30 away from the cabinet door 20 is the turn-up structure 340 for detachably connecting with the backing plate 410 of the shutter structure 40.

[0053] In the embodiment, as shown in Figure 2 , Figure 8 and Figure 9As shown, the top frame 310 and the side frame 320 each have a first connecting section 360, which is a plate section welded with the cabinet door 20, the first connecting section 360, the extending section 350 and the flange structure 340 are sequentially connected and cooperatively form a U-shaped groove structure with the notch facing away from the through hole 210. The top frame 310 and the side frame 320 are integrally formed U-shaped structures, the first connecting section 360 is arranged in a surface-to-surface structure with the cabinet door 20, which is conducive to increasing the contact area and thus improving the welding strength, and meanwhile the arrangement of the flange structure 340 is conducive to increasing the contact area between the flange structure 340 and the lining plate 410, thereby improving the stability of the connection between the frame 30 and the lining plate 410.

[0054] In the present embodiment, as shown in Figure 2 、 Figure 10 and Figure 11 , the bottom frame 330 includes a first section 331, a second section 332 and a third section 333 sequentially connected by bending, the flange structure 340 is arranged at the first end of the first section 331, the second end of the first section 331 is connected with the top end of the second section 332, the second section 332 is arranged at the lower side of the first section 331, the first section 331 forms the extending section 350 of the bottom frame 330, the bottom end of the second section 332 is connected with the first end of the third section 333, the third section 333 is a plate section for connecting with the cabinet door 20, wherein the second end of the third section 333 is connected with the cabinet door 20, the third section 333 is arranged at the lower side of the second section 332, and the second end of the third section 333 divides the through hole 210 of the bottom row into a first part and a second part arranged along the height direction of the cabinet body 10.

[0055] The frame 30 has a first projection along the width direction of the cabinet body 10, the first part has a second projection along the width direction of the cabinet body 10, and the second part has a third projection along the width direction of the cabinet body 10, wherein the second projection is completely covered by the first projection, and the third projection does not coincide with the first projection.

[0056] The two ends of the bottom frame 330 along the length direction of the cabinet body 10 are welded and fixed with the side frame 320, and the first section 331, the second section 332, the third section 333 and the flange structure 340 are integrally formed.

[0057] Specifically, the second end of the third section 333 is arranged at the lower side of the center position of the through hole 210 of the bottom row, and the inside of the area enclosed by the frame 30 is provided with multiple rows of through holes 210, and the third section 333 is correspondingly arranged with the through holes 210 of the bottom row along the height direction of the cabinet body 10, so as to realize that when the rainwater enters the inside of the cabinet body 10 through the through hole 210, the third section 333 has a guide function for the rainwater, so that the rainwater quickly flows along the inclined guide surface formed by the third section 333 to the through hole 210 and flows out to the outside of the cabinet body 10 through the through hole 210, thereby realizing drainage.

[0058] In this embodiment, in the height direction of the cabinet 10, the distance H between the center of the bottom through hole 210 and the second end of the third segment 333 satisfies the condition that 1mm ≤ RH ≤ 2mm with respect to the radius R of the bottom through hole 210. For example, RH can be 1mm, 1.5mm, 2mm, etc. A difference between the distance H between the center and the second end of the third segment 333 and the radius R of the through hole 210 that is too small or too large is detrimental to rainwater flow. Specifically, if it is too small, rainwater will accumulate at the connection area between the cabinet door 20 and the third segment 333; if it is too large, it will affect the flow area of ​​the through hole 210, thus hindering rainwater flow.

[0059] In this embodiment, the second end of the first segment 331 is bent toward the bottom side of the cabinet 10 to form an inclined guide surface. The first segment 331 and the flange structure 340 form a bent structure, which is beneficial to the guiding effect of rainwater and thus improves drainage efficiency.

[0060] Specifically, the bending angle A satisfies 10°≤A≤20°.

[0061] In this embodiment, the second end of the third segment 333 is bent toward the bottom side of the cabinet 10 to form an inclined guide surface. The third segment 333 and the second end form a bent structure, which is beneficial for blocking rainwater from entering and for draining rainwater.

[0062] Specifically, the bending angle B satisfies 10°≤B≤20°.

[0063] In this embodiment, the second segment 332 and the flanged structure 340 are generally arranged in a parallel configuration to allow the first segment 331 and the third segment 333 to be spaced apart along the height direction of the cabinet 10. Along the height direction of the cabinet 10, the bottom end of the blade 420 is positioned between the first segment 331 and the third segment 333. The blade 420 forms an airflow channel; the area between the bottom end of the blade 420 and the first segment 331 and the third segment 333 not only forms an airflow channel but also effectively blocks splashing rainwater from entering and allows rainwater to drain.

[0064] like Figures 2 to 5 As shown, the liner 410 includes an outer frame 412 and a flange 411 disposed on the inner periphery of the outer frame 412. The flange 411 is bent toward the cabinet door 20. The blades 420 are connected to the flange 411 at both ends along the length of the cabinet body 10.

[0065] Specifically, the liner 410 has a frame structure, and the louver structure 40 includes multiple blades 420. The multiple blades 420 are spaced apart along the height direction of the cabinet 10. The two ends of each blade 420 in the length direction are welded and fixed to the flange 411 on the liner 410. An air duct structure is formed between two adjacent blades 420 along the height direction of the cabinet 10 to facilitate air circulation and heat dissipation.

[0066] In the embodiment, the blade 420 comprises a first plate segment 421, a second plate segment 422 and a third plate segment 423 connected in sequence, the first plate segment 421 is parallel to the cabinet door 20, a first end of the second plate segment 422 is connected to a bottom end of the first plate segment 421, a second end of the second plate segment 422 is bent towards one side of the cabinet door 20 and extends towards a bottom end of the cabinet door 20, one end of the third plate segment 423 is connected to the second end of the second plate segment 422, and the other end of the third plate segment 423 is bent towards one side of the cabinet door 20 and extends towards the bottom end of the cabinet door 20.

[0067] Specifically, the blade 420 of the present application adopts an integrated three-segment structure, and the sequentially bent structure is conducive to blocking the water vapor and rainwater vertically blown to the air vent, thereby avoiding the water vapor and rainwater from entering the inside of the cabinet 10, and improving the drainage performance.

[0068] In the embodiment, the energy storage cabinet further comprises sealing glue, the frame 30 is welded to the cabinet door 20, and the sealing glue is arranged in the welding seam between the frame 30 and the cabinet door 20. By applying the sealing glue in the welding seam, the rainwater and water vapor are prevented from penetrating into the inside of the cabinet 10 from the welding seam, the sealing glue has the effect of blocking the rainwater and water vapor from entering the cabinet 10, and the waterproofness of the overall structure is improved.

[0069] From the above description, it can be seen that the above-mentioned embodiments of the present application achieve the following technical effects:

[0070] The energy storage cabinet of the present application fixes the frame 30 on the cabinet door 20, connects the lining plate 410 and the frame 30 by using the connecting structure, and then realizes the fixed installation of the louver structure 40.
