[0035] like Figure 1 and Figure 2 As shown, the structural diagram of the household energy storage box in the embodiment of the utility model, Figure 2 The exploded view of the household energy storage box in the embodiment of the present invention is shown. The household energy storage box includes: a box body 3, a panel 2 and an upper cover 1; the box body 3, the panel 2 and the upper cover 1 enclose a storage space, and the storage space is used to install the energy storage battery; the box body 3 has two side panels 301, a back panel 303 and a bottom panel 302; the first surface 3011 and the second surface 3013 of the side panel 301 are provided with a first card slot 3012 and a second card slot 3014; the rear end surface of the panel 2 is provided with a first buckle 201 that engages with the first card slot 3012 on both sides, and the panel 2 is provided with a through slot, and a display is installed in the first through slot. display 202; and the display screen of the display 202 is arranged on the front end surface of the panel 2, for displaying various data of the energy storage battery, the upper end surface of the panel 2 is provided with a snap plate 203, and the snap plate 203 is provided with a third card slot 204; the lower end surface of the upper cover 1 is provided with a second snap 101 that engages with the second card slot 3014 and a third snap 102 that cooperates with the third card slot 204, the second snap 101 is located on both sides of the lower end surface of the upper cover 1, and the third snap 102 is located at the front end of the lower end surface of the upper cover 1.

[0036] The panel 2 is attached to the first surface 3011, and the upper cover 1 is attached to the second surface 3013, forming a storage space with the housing 3 for mounting products and equipment such as energy storage batteries. The snap structures of the first and second snaps 201, 101 can be implemented in a variety of ways, including spring snaps, buckle snaps, slot snaps, rotating snaps, and push-pull snaps. In one implementation, the upper cover 1 and panel 2 are connected to the first and second surfaces 3011, 3013 of the side panels 301 using slot-shaped snaps. The snaps engage in the slots, allowing the panel 2 to be mounted on the first surface 3011, and the upper cover 1 to be mounted on the second surface 3013. Among them, the matching form of the buckle and the slot can be completely embedded (that is, the shape of the buckle and the slot is exactly the same), or the buckle can be locked in the slot after sliding a specific trajectory in the slot. Specifically, when the buckle and the slot are completely embedded, the buckle can be rectangular, triangular, or other polygons, and the structure of the slot can be a rectangular slot, triangular slot, or other structures with the same shape as the buckle. During installation, the panel 2 and the upper cover 1 can be fixed to the first surface 3011 and the second surface 3013 of the two side panels 301 by the friction between the buckle and the slot, or the buckle or the slot is made of magnetic material and fixed by magnetic attraction. In this embodiment, the panel 2 and the upper cover 1 are connected to the box body 3 by buckles, which not only improves the efficiency of product assembly, but also has no bolt heads and bolt holes on the appearance, making it more beautiful.

[0037] Among them, Figure 4 and Figure 5 As shown, in this embodiment, the buckle and the slot adopt an installation method in which the buckle slides along a specific trajectory in the slot and then engages in the slot. In this implementation, the panel 2 is installed first and then the upper cover 1 is installed. When the first buckle 201 on the panel 2 is installed in the first slot 3012, it needs to move downward a first predetermined distance before it is engaged and fixed with the first slot 3012. When the second buckle 101 of the upper cover 1 is installed in the second slot 3014, it needs to move backward a predetermined second predetermined distance before it is engaged and fixed with the second slot 3014. During this process, the third buckle 102 engages with the third slot 204, completing the installation of the household energy storage box.

[0038] like Figure 2 and Figure 3 As shown, in another embodiment, the first slot 3012 and the second slot 3014 are both rectangular structures, each comprising a guide portion 3012a and a fixing portion 3012b connected to each other. The buckle structure is embedded in the guide portion 3012a and moves along the guide portion 3012a into the fixing portion 3012b for engagement. The slot comprises a guide portion 3012a and a fixing portion 3012b connected to each other. The buckle is embedded in the guide portion 3012a and moves along the guide portion 3012a into the fixing portion 3012b for engagement. The slot trajectory formed by the guide portion 3012a and the fixing portion 3012b of the slot can be in an "I" shape or a "7" shape, for example. The buckle is first inserted into the guide portion 3012a and then moves along the guide portion 3012a into the fixing portion 3012b to be secured to the main body of the box 3. Among them, a chamfered structure can be provided at the connection between the guide portion 3012a and the fixed portion 3012b to facilitate the buckle to enter the fixed portion 3012b. Specifically, the matching mode of the buckle and the fixed portion 3012b can also be various. For example, the buckle is a barb structure, wherein the buckle includes a fitting portion 201b and a snap-fit ​​portion 201a, and the angle between the fitting portion 201b and the snap-fit ​​portion 201a is between 30°-90°. The fixed portion 3012b can be a rectangular groove, the fitting portion 201b is fitted with the fixed portion 3012b, and the snap-fit ​​portion 201a contacts and snaps with the main body of the box body 3, thereby limiting the movement of the panel 2 and the upper cover 1. Among them, the snap-fit ​​portion 201a snaps into the main body of the box body 3, and the shape of the slot can be various. For example Figure 4As shown, in one implementation, the engaging portion 201b and the locking portion 201a are connected to each other and are perpendicular, and the slot is a rectangular structure parallel to the side of the panel 2, that is, the buckle moves up and down in the slot, which facilitates the installation and disassembly of the panel 2 or the upper cover 1, and the guide portion 3012a of the slot is the upper part of the rectangular structure, and the engaging portion 201b is the lower part of the rectangular structure. The engaging portion 201b and the locking portion 201a of the buckle enter from the guide portion 3012a. In the process of the buckle moving along the guide portion 3012a, the engaging portion 201b is in the space surrounded by the edge of the slot, and the locking portion 201a is outside the space; when the buckle moves to the fixed portion 3012b of the slot, the fixed portion 3012b of the slot abuts against the engaging portion 201b of the buckle, and the locking portion 201a abuts against the main body of the box 3, thereby fixing the panel 2 or the upper cover 1. Among them, a chamfer can be set on the side of the locking portion 201a to prevent the end face of the locking portion 201a from being stuck with the fixing portion 3012b during the movement of the buckle, thereby facilitating the installation of the buckle in the slot.

[0039] Among them, Figure 1 As shown, in one embodiment of the present utility model, a first fixing hole 205 is provided on the lower end surface of the panel 2, a first accommodating hole 3022 is opened on the base plate 302, a first fixing member is installed in the first accommodating hole 3022, and the panel 2 is fixedly connected to the base plate 302 through the cooperation between the first fixing member and the first fixing hole 205; a second fixing hole 103 is provided on the rear end surface of the upper cover 1, a second accommodating hole 3031 is provided on the back plate 303, a second fixing member is installed in the second accommodating hole 3031, and the upper cover 1 is fixedly connected to the back plate 303 through the cooperation between the second fixing member and the second fixing hole 103.

[0040] After the buckle is connected to the slot, the buckle can still move along the slot. Therefore, a first fixing member is installed in the first receiving hole 3022, and the panel 2 is fixedly connected to the bottom plate 302 by the cooperation of the first fixing member and the first fixing hole 205. A second fixing member is installed in the second receiving hole 3031, and the upper cover 1 is fixedly connected to the back plate 303 by the cooperation of the second fixing member and the second fixing hole 103. The first fixing member and the first fixing hole 205, and the second fixing member and the second fixing hole 103 can be fixed by riveting, threading, mortise and tenon, etc. In one implementation, the first fixing member and the second fixing member are both screws, and threads are provided in the first fixing hole 205 and the second fixing hole 103. After the panel 2 and the upper cover 1 are installed, the panel 2 and the upper cover 1 are completely fixed to the box body 3 by threading. Furthermore, the first fixing hole 205 is arranged on the lower end surface of the panel 2. After the installation is completed, the first fixing hole 205 and the screw can be hidden, so that the surface of the box body 3 in the embodiment of the utility model is smoother and more beautiful. The second fixing hole 103 in the upper cover 1 is arranged on the rear end surface of the upper cover 1, and the function is the same.

[0041] In one implementation, when the slot is rectangular, the buckle moves vertically up and down along the slot, and a reset hole is provided on the lower end surface of the panel 2, in which a spring is installed. One end of the spring is located in the reset hole, and the other end protrudes out of the reset hole. When the buckle on the panel 2 is inserted into the guide portion 3012a in the slot, the other end of the spring contacts the upper end surface of the base plate 302 and provides support for the panel 2. At this point, the panel 2 can be pressed downward to completely press the spring into the reset hole, and the first buckle 201 is engaged in the first slot 3012, completing the installation of the panel 2. The panel 2 is fixed to the base plate 302 via the first fixing member. In this implementation, when the panel 2 is removed, the spring is released by removing the first fixing member, allowing the spring to lift the panel 2, thereby causing the buckle to rise to the guide portion 3012a of the slot. This eliminates the need for the user to lift the panel 2, facilitating removal.

[0042] Alternatively, when installing the upper cover 1, the third clip 102 of the upper cover 1 cooperates with the third slot 204 of the panel 2, thereby limiting the vertical movement of the panel 2. When the upper cover 1 is removed, the spring is also released, so that the spring can lift the panel 2, thereby causing the clip to rise to the guide part 3012a of the slot, eliminating the user's action of lifting the panel 2, making disassembly easier.

[0043] Among them, Figure 1As shown, in one embodiment of the utility model, the upper end surface of the panel 2 abuts against the lower end surface of the upper cover 1, and the front end surface of the panel 2 is flush with the front end surface of the upper cover 1, so as to align the edge of the upper end surface of the panel 2 with the edge of the lower end surface of the upper cover 1; the lower end surface of the panel 2 abuts against the upper end surface of the bottom plate 302, and the front end surface of the panel 2 is flush with the front end surface of the bottom plate 302, so as to align the edge of the lower end surface of the panel 2 with the edge of the upper end surface of the bottom plate 302; the rear end surface of the panel 2 is in contact with the first surface 3011, and the side surface of the panel 2 is flush with the outer surface of the side plate 301, so as to align the side edge of the panel 2 with the edge of the side plate 301. This ensures that the end surfaces of the panel 2 and the upper cover 1 are flush with and in close contact with the box body 3, thereby enhancing the aesthetics of the surface of the household energy storage box in the embodiment of the utility model.

[0044] In one embodiment of the utility model, the upper end surface of the base plate 302 includes a storage area and a fixing area; the first accommodating hole 3022 is arranged in the fixing area, and the lower end surface of the panel 2 is in contact with the fixing area; a pad 3021 is installed in the storage area for placing the energy storage battery.

[0045] The bottom plate 302 has connection holes and connectors connected to the side plates 301, the back plate 303 and other components, so that the energy storage battery cannot be placed directly on the bottom plate 302. Therefore, a pad 3021 is provided on the bottom plate 302 to better preserve the energy storage battery.

[0046] Among them, Figure 2 and Figure 4 As shown, in one embodiment of the utility model, a guide plate 304 is installed on the first surface 3011 , and the guide plate 304 is used to guide the first buckle 201 to engage with the first slot 3012 and support the panel 2 .

[0047] In this embodiment, the middle part of the panel 2 is a cavity structure. During the process of installing the panel 2 on the first surface 3011, the guide plate 304 is located in the cavity structure. During this period, the installer is facing the front of the panel 2, and the panel 2 blocks the installer's field of vision. When the first clip 201 is laterally offset from the first slot 3012, the first clip 201 contacts the guide plate 304, thereby prompting the installer of the installation status of the first clip 201 and the first slot 3012.
