[0036] See also Figures 1 to 8 As shown, according to an embodiment of the present application, a top cover structure is provided, which includes a top cover body 10.

[0037] Specifically, the top cover body 10 in this embodiment includes a body 11 and a protrusion 12, the body 11 includes a first side surface 111, and the protrusion 12 is arranged at the outer edge of the first side surface 111 and faces the first direction ( Figure 4 The top cover body 10 is provided with a ventilation channel 13, which extends along the interior of the top cover body 10, and the two ends of the ventilation channel 13 are respectively located on the first side 111 and the end 121.

[0038] When the top cover structure in this embodiment is actually used, the top cover structure is placed on the top of the energy storage cabinet. At this time, the first side 111 of the top cover body 10 is located at the bottom of the top cover structure, and the raised portion 12 protrudes from the first side 111 and protrudes toward the bottom of the top cover structure. Since the top cover structure in this embodiment is provided with a ventilation channel 13 inside, and the two ports of the ventilation channel 13 are respectively located on the first side 111 and the end 121, at this time, the heat inside the energy storage cabinet can enter the ventilation channel 13 from the first side 111, flow along the inside of the top cover body 10 to the end 121 of the raised portion 12 and enter the external environment, which is convenient for effectively dissipating the heat of the energy storage cabinet. At the same time, when the energy storage cabinet is used outdoors, rainwater and the like fall on the top of the top cover structure (the side away from the first side 111), and then flow along the top of the top cover structure, and then fall to the ground from the end 121 of the raised portion 12 under the action of gravity.

[0039] It can be seen that in this embodiment, the ventilation channel 13 is arranged inside the top cover body 10, and the two ports of the ventilation channel 13 are respectively located on the first side surface 111 and the end 121 of the protrusion 12. In this way, it is not only convenient to dissipate heat for the energy storage cabinet using the top cover structure, but also the energy storage cabinet using the top cover structure is convenient to use outdoors to prevent rainwater from penetrating.

[0040] See also Figures 3 to 8 As shown, in this embodiment, a cavity 131 is provided inside the top cover body 10, at least one first ventilation hole 132 is provided on the first side 111, the first ventilation hole 132 is connected to the cavity 131, at least one second ventilation hole 133 is provided on the end 121, the second ventilation hole 133 is connected to the cavity 131, and the first ventilation hole 132, the cavity 131 and the second ventilation hole 133 form the above-mentioned ventilation channel 13. In this embodiment, the ventilation channel 13 is formed by providing the cavity 131 to be connected with the first ventilation hole 132 and the second ventilation hole 133. Compared with general straight flow channels or curved flow channels, the cavity 131 has a relatively spacious space and is more suitable for heat exchange to effectively dissipate heat for structures such as energy storage cabinets.

[0041] In one embodiment of the present application, the top cover body 10 includes a bottom plate 101 and a cover plate 102, and the cover plate 102 is covered on the bottom plate 101. In this embodiment, the top cover body 10 is set as two parts of the bottom plate 101 and the cover plate 102, and the bottom plate 101 and the cover plate 102 are both sheet metal parts. The first ventilation hole 132 mentioned above is provided on the bottom plate 101, and the outer edge of the cover plate 102 is provided with the above-mentioned raised portion 12. After the bottom plate 101 is covered on the cover plate 102, the cavity body 131 mentioned above can be formed by surrounding, and the structure is simple and easy to process. During assembly, the cover plate 102 and the bottom plate 101 can be connected by at least one of snap-fit, welding or fasteners 30. The drawings of the present application show the situation when the cover plate 102 and the bottom plate 101 are connected by fasteners 30, and the fasteners 30 can be structures such as fastening screws, fastening pins or fastening bolts. The bottom plate 101 in this embodiment is a rectangular plate-shaped structure, and the cross section of the cover plate 102 is generally triangular, so that water droplets on the cover plate 102 can be easily transported downward.

[0042] In order to further improve the heat dissipation effect of the top cover structure in this embodiment, the cavity 131 in this embodiment is a cavity extending along the height, width and length directions inside the top cover body 10. During actual processing and production, the cavity 131 can be set as large as possible inside the top cover body 10 to facilitate effective heat dissipation of structures such as energy storage cabinets.

[0043] Furthermore, in the present embodiment, there are multiple first ventilation holes 132 and multiple second ventilation holes 133, wherein multiple first ventilation holes 132 are arranged in an array on the first side 111, that is, the first ventilation holes 132 are arranged in multiple rows and columns on the first side 111, so that the heat in the energy storage cabinet can be quickly transported from the first ventilation holes 132 to the cavity 131, and finally released from the second ventilation holes 133. Of course, in other embodiments of the present application, the first ventilation holes 132 can also be arranged on the first side 111 in other regular or irregular ways, as long as they are other deformation modes under the concept of the present application, they are all within the protection scope of the present application. Multiple second ventilation holes 133 are arranged at intervals along the periphery of the top cover body 10, so as to facilitate the hot air in the cavity 131 to be transported to the external environment.

[0044] Optionally, the second ventilation hole 133 in the present embodiment is arranged on the side of the end 121 close to the top cover body 10, that is to say, the second ventilation hole 133 is located on the inner side of the end 121. When liquids such as rainwater flow downward from the top of the top cover structure, it is not easy to enter the second ventilation hole 133 and enter the interior of the top cover structure, which makes it safer and more reliable to use.

[0045] For example, the first ventilation hole 132 or the second ventilation hole 133 in the present embodiment may be at least one of a circular hole, a square hole or a rectangular hole. The drawings of the present application show the case where the first ventilation hole 132 is a circular hole and the second ventilation hole 133 is a square hole. Of course, in other embodiments of the present application, the first ventilation hole 132 or the second ventilation hole 133 may also be a triangular hole, an elliptical hole, other polygonal or special-shaped holes, as long as it is other deformation methods under the concept of the present application, they are all within the protection scope of the present application.

[0046] In one embodiment of the present application, the second ventilation hole 133 is set as a rectangular hole, and the length*width of the rectangular hole is (8mm-12mm)*(13mm-17mm), such as 8mm*13mm, 9mm*15mm, 8mm*15mm, 10mm*15mm, 12mm*17mm, 11mm*17mm, 10mm*17mm, etc. When the length*width of the rectangular hole is less than 8mm*13mm, it is not convenient to dissipate heat for the energy storage cabinet; when the length*width of the rectangular hole is greater than 13mm*15mm, it is easy to affect the structural strength of the top cover structure.

[0047] Optionally, in the present embodiment, there are multiple first ventilation holes 132, and the multiple first ventilation holes 132 are arranged in an array on the first side 111, and the spacing L1 between two adjacent first ventilation holes 132 is 10mm to 100mm, for example, 10mm, 20mm, 30mm, 40mm, 50mm, 60mm, 70mm, 80mm, 90mm or 100, etc. When the spacing L1 between two adjacent first ventilation holes 132 is less than 10mm, the first ventilation holes 132 are arranged relatively densely, which easily reduces the structural strength of the top cover structure; when the spacing L1 between two adjacent first ventilation holes 132 is greater than 100mm, the first ventilation holes 132 on the first side 111 are relatively sparse, which is not convenient for rapid heat dissipation of the energy storage cabinet using the top cover structure. In this embodiment, the aperture d of the first ventilation hole 132 is 7 mm to 20 mm, for example 7 mm, 10 mm, 12 mm, 15 mm, 17 mm, 20 mm, etc. When the aperture d of the first ventilation hole 132 is less than 7 mm, it is not convenient to dissipate heat for structures such as the energy storage cabinet. When the aperture d of the first ventilation hole 132 is greater than 20 mm, it is easy to reduce the structural strength of the top cover structure.

[0048] Furthermore, the spacing L between two adjacent second ventilation holes 133 is 23 mm to 25 mm, for example 23 mm, 24 mm, 25 mm, etc. When the spacing L between two adjacent second ventilation holes 133 is less than 23 mm, it is easy to reduce the strength of the top cover structure. When the spacing L between two adjacent second ventilation holes 133 is greater than 25 mm, it is not convenient to ventilate into the cavity 131.

[0049] Recombination Figures 1 to 8 As shown, a groove 122 extending along the outer edge of the main body 11 is provided on the inner side of the raised portion 12 in this embodiment, and the groove 122 is connected to the cavity body 131. The second ventilation hole 133 is located at the bottom of the groove 122, and the depth direction of the groove 122 is consistent with the height direction of the raised portion 12, and the depth H of the groove 122 along the height direction of the raised portion 12 is 32mm to 36mm, for example, 32mm, 33mm, 34mm, 35mm, 36mm, etc., such a setting can not only prevent water on the top of the top cover structure from entering the cavity body 21 from the second ventilation hole 133, but also can reduce the processing and manufacturing cost of the structure in this embodiment as much as possible; optionally, the width D of the groove 122 along the inner and outer directions of the main body 11 is 16mm to 20mm, for example, 16mm, 17mm, 18mm, 19mm or 20mm, etc. During actual processing, the groove 122 is formed by bending at the outer edge of the cover plate 102. In this embodiment, by setting the width D of the groove 122 along the inner and outer directions of the main body 11 to 16 mm to 20 mm, the bending and forming of the groove 122 is more convenient, which meets the waterproof requirements of the top cover structure and can further reduce the production cost of the top cover structure in this embodiment.

[0050] Optionally, the raised portion 12 includes an annular raised portion, which is arranged around the outer periphery of the top cover body 10. By setting the raised portion 12 as an annular raised portion, it is more suitable to set a circle of second ventilation holes 133 on the outer periphery of the top cover body 10, so as to facilitate heat dissipation of structures such as energy storage cabinets using the top cover structure.

[0051] Furthermore, the top cover structure in this embodiment also includes an annular sealing strip 20, which is arranged on the first side surface 111 and located on the inner side of the annular protrusion 12. When the top cover structure is installed on the energy storage cabinet, the setting of the annular sealing strip 20 can prevent external water from entering the interior of the energy storage cabinet and other structures using the top cover structure. Optionally, the annular sealing strip 20 can be a sealing rubber strip, a sealing silicone strip or other structures. As long as it is other deformation methods under the concept of this application, it is within the protection scope of this application. At the same time, during actual processing, the fastener 30 in this embodiment is arranged on the inner side of the annular sealing strip 20, so that rainwater can be prevented from penetrating into the interior of the energy storage cabinet from the fastener 30.

[0052] According to the above description, it can be known that the top cover structure of the present application sets the second ventilation hole 133 downward through an innovative structural design, so that rainwater can be quickly drained and ventilation is convenient. When using the top cover structure, rainwater can only rebound into the drainage hole after impacting the side wall of the cabinet. Because there is a groove 122 on the inside of the raised part. Unless the rainwater can exceed the depth of the groove 122, it is possible to flow into the top cover. The second ventilation holes 133 of the present application are arranged in a row along the periphery of the main body 11, so the rainwater will flow out quickly downward. The protection level of the top cover structure can reach IPX5.

[0053] On the other hand, the present application also provides an energy storage cabinet, which includes the above-mentioned top cover structure. Therefore, the energy storage cabinet includes all the technical effects of the top cover structure described in the above embodiment. Since the technical effects of the top cover structure have been described in detail above, they will not be repeated here.

[0054] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0055] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0056] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
