Technical Field

[0001] This utility model relates to the field of energy storage equipment technology, and in particular to an energy storage enclosure and a household energy storage device. Background Technology

[0002] Residential energy storage systems are integrated energy storage devices designed specifically for homes. They combine photovoltaic inverters, energy storage batteries, and intelligent energy management to achieve self-consumption, emergency backup, or peak-valley arbitrage by storing electrical energy (such as photovoltaic power generation or low-priced electricity from the grid). The core components include battery packs, inverters, and energy management systems.

[0003] like Figure 1 As shown, existing rectangular residential energy storage enclosures with an IP65 waterproof rating typically involve riveting screws 11 to the enclosure cover 1, then fastening the cover 1 to the opening of the enclosure 2, and finally tightening the screws 11 and nuts 21 along their circumferential mating surfaces to achieve a fixed connection between the cover 1 and the enclosure 2. However, in actual operation, this assembly method requires the enclosure 2 to be placed flat, and the nuts 21 need to be tightened horizontally below the mating surfaces of the two enclosures. This results in limited operating space and a narrow field of vision, making the assembly of the enclosure 2 and the cover 1 less convenient. Utility Model Content

[0030] This disclosure provides an energy storage enclosure, including an upper cover, a lower enclosure, and multiple fasteners. The upper cover has a plurality of screw positioning holes evenly distributed around its opening periphery; the lower enclosure has an opening periphery with a connected outwardly convex bent portion and an inwardly folded sealing portion; the outwardly convex bent portion protrudes away from the outer side of the lower enclosure, and the inwardly folded sealing portion is used to seal against the inner bottom wall of the upper cover; each fastener includes a screw and a waterproof nut; the upper cover is disposed on the lower enclosure, such that each waterproof nut is aligned with the corresponding screw positioning hole; each waterproof nut is vertically riveted to the outwardly convex bent portion and extends into the inner side of the outwardly convex bent portion, and each screw passes through the corresponding screw positioning hole and is threadedly connected to the waterproof nut.

[0031] Please see Figures 2 to 6 To better understand the energy storage enclosure 10 of this application, the following further explanation of the energy storage enclosure 10 is provided:

[0032] One embodiment of the energy storage enclosure 10 includes an upper cover 100, a lower enclosure 200, and a plurality of fasteners 300. The upper cover 100 has a plurality of screw positioning holes 101 evenly provided around its opening; the lower body 200 has an outwardly convex bending portion 210 and an inwardly folded sealing portion 220 connected around its opening; the outwardly convex bending portion 210 protrudes away from the outer side of the lower body 200, and the inwardly folded sealing portion 220 is used to seal against the inner bottom wall of the upper cover 100; each fastener 300 includes a screw 310 and a waterproof nut 320; the upper cover 100 covers the lower body 200, such that each waterproof nut 320 is aligned with the corresponding screw positioning hole 101; each waterproof nut 320 is vertically riveted to the outwardly convex bending portion 210 and extends inside the outwardly convex bending portion 210, and each screw 310 passes through the corresponding screw positioning hole 101 and is threadedly connected to the waterproof nut 320.

[0033] In this embodiment, the present invention provides an outwardly protruding bent portion 210 and an inwardly folded sealing portion 220 connected around the opening of the lower housing 200. When the upper housing cover 100 is placed on the lower housing 200, the waterproof nut 320 is aligned with the screw positioning hole 101. Thus, when assembling the upper housing cover 100 and the lower housing 200, since the waterproof nut 320 is vertically riveted to the outwardly protruding bent portion 210, the screw 310 can be horizontally inserted into the screw positioning hole 101 and threadedly connected to the waterproof nut 320. When the lower housing 200 is placed flat, the screw 310 can be tightened to the waterproof nut 320 from the outside of the opening of the upper housing cover 100 through the screw positioning hole 101. This provides a larger operating space and a better field of vision, significantly improving the ease of assembly between the lower housing 200 and the upper housing cover 100.

[0034] like Figures 2 to 4 As shown, in one embodiment, the outwardly convex bending portion 210 is perpendicular to the inwardly folded sealing portion 220. In one embodiment, the energy storage enclosure 10 further includes a waterproof sealing strip 400, which is disposed between the inwardly folded sealing portion 220 and the inner bottom wall of the upper enclosure cover 100, and is bonded to the inwardly folded sealing portion 220 or the inner bottom wall of the upper enclosure cover 100.

[0035] It is understood that in this embodiment, the outwardly convex bending portion 210 and the inwardly folded sealing portion 220 are arranged perpendicularly. In this way, when the upper box cover 100 and the lower box body 200 are assembled, that is, when the upper box cover 100 is placed on the lower box body 200, the inwardly folded sealing portion 220 can press the waterproof sealing strip 400 against the inner bottom wall of the upper box cover 100 to form a waterproof seal.

[0036] like Figures 2 to 5 As shown, in one embodiment, the outwardly convex bent portion 210 is evenly provided with a plurality of through holes 2101. Each waterproof nut 320 is riveted to the inner side of the outwardly convex bent portion 210 and aligned with the corresponding through hole 2101. In this way, the waterproof nut 320 is built into the lower housing 200, so that the screw 310 can be sequentially inserted into the screw positioning hole 101 and the through hole 2101, and finally threadedly connected to the threaded hole of the waterproof nut 320.

[0037] like Figure 4As shown, in one embodiment, the height of the protruding bending portion 210 from the outer side of the lower housing 200 is 3mm to 5mm. Thus, after the upper cover 100 and the lower housing 200 are erected, the protruding bending portion 210 from the outer side of the lower housing 200 makes it difficult for water on the surface of the lower housing 200 to penetrate to the position of the waterproof sealing strip 400, thereby preventing water from penetrating into the interior of the lower housing 200. Specifically, in this embodiment, the height of the protruding bending portion 210 from the outer side of the lower housing 200 is 4mm.

[0038] like Figure 5 and Figure 6 As shown, in one embodiment, the upper cover 100 and the lower box body 200 are both integrally formed structures. This ensures that the upper cover 100 and the lower box body 200 have good structural strength.

[0039] Please see Figures 2 to 6 This application also provides a residential energy storage device, including a structural strength component 500 and the energy storage enclosure 10 described in any of the above embodiments, wherein the structural strength component 500 is fixedly installed on the inner side wall of the lower enclosure 200.

[0040] In this embodiment, the residential energy storage device uses the aforementioned energy storage chassis 10. A connected outwardly protruding bent portion 210 and an inwardly folded sealing portion 220 are provided around the opening of the lower chassis 200. When the upper cover 100 is placed over the lower chassis 200, the waterproof nut 320 is aligned with the screw positioning hole 101. Thus, when assembling the upper cover 100 and the lower chassis 200, the waterproof nut 320 is vertically riveted to the outwardly protruding bent portion 210, and the screw 310 can be horizontally inserted into the screw positioning hole 101 to connect with the waterproof nut 320. When the lower chassis 200 is placed flat, the screw 310 can be tightened onto the waterproof nut 320 from the outside of the opening of the upper cover 100 through the screw positioning hole 101. This provides a larger operating space and a better field of vision, significantly improving the ease of assembly between the lower chassis 200 and the upper cover 100.

[0041] Furthermore, by welding or screwing the strength structural component 500 to the inner wall of the lower housing 200, the overall structural strength of the lower housing 200 is well ensured.

[0042] like Figure 5 As shown, in one embodiment, the residential energy storage device further includes a plurality of casters 600, which are located on the outside of the lower housing 200. Specifically, multiple casters 600 are installed at the bottom of the residential energy storage device to facilitate user movement of the device.

[0043] Compared with the prior art, the present invention has at least the following advantages:

[0044] This utility model features a connected outwardly protruding bent portion and an inwardly folded sealing portion around the opening periphery of the lower housing. When the upper housing cover is placed on the lower housing, the waterproof nut is aligned with the screw positioning hole. When assembling the upper housing cover and the lower housing, the waterproof nut is vertically riveted to the outwardly protruding bent portion, and the screw can be horizontally inserted through the screw positioning hole to connect with the waterproof nut. When the lower housing is laid flat, the screw can be tightened onto the waterproof nut from the outside of the opening periphery of the upper housing cover through the screw positioning hole. This provides a larger operating space and a better field of vision, significantly improving the ease of assembly between the lower housing and the upper housing cover.

[0045] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
