[0044] Please refer to the following Figures 1 to 10 The household solar storage device provided in this embodiment is described.

[0045] Please refer to Figures 1 to 4 Specifically, the household photovoltaic storage device includes a plurality of stacked battery packs 10, and at least one side wall of the battery pack 10 is provided with a snap-in button 20 and a snap-in hole 30 on both sides along the stacking direction, respectively. The snap-in button 20 has a first working position and a second working position along a direction perpendicular to the side wall. When the snap-in button 20 is in the first working position, the snap-in button 20 of one battery pack 10 can avoid the snap-in hole 30 of another battery pack 10; when the snap-in button 20 is in the second working position, the snap-in button 20 of one battery pack 10 can be snapped into the snap-in hole 30 of another battery pack 10.

[0046] The household photovoltaic storage device in this embodiment is provided with a snap-in button 20 and a snap-in hole 30. When stacking and installing several battery packs 10, the snap-in hole 30 of one battery pack 10 and the snap-in button 20 of the adjacent battery pack 10 are first set in the same direction, and then the two are stacked in the stacking direction. During the stacking process, the snap-in button 20 is in the first working position to avoid the stacked battery packs 10. After the two are stacked, the snap-in button 20 is replaced to the second working position to achieve the snap-in connection between the snap-in button and the snap-in hole 30, thereby achieving the fixation of the two battery packs 10. By analogy, the stacking and fixation of multiple battery packs 10 can be achieved; if disassembly is performed, the snap-in button 20 can be directly replaced to the first working position to achieve the disassembly of the adjacent battery packs 10. In summary, the household photovoltaic storage device can achieve the rapid disassembly and assembly of the battery pack 10, and the operation is simple, it has a certain aesthetics, improves the working efficiency, and reduces the maintenance cost.

[0047] It should be noted that the first working position is the position of the snap-in button 20 facing the inside of the battery pack 10 along a direction perpendicular to the side wall, at this time, the snap-in button 20 is away from the snap-in hole 30; the second working position is the position of the snap-in button 20 away from the battery pack 10 along a direction perpendicular to the side wall, at this time, the snap-in button 20 is snapped into the snap-in hole 30.

[0048] Optionally, the household solar storage device is composed of a plurality of stacked battery packs 10 to form a battery group, and the side walls of the battery packs 10 on both sides of the battery group are not provided with snap-in buttons 20 or snap-in holes 30 on the side away from the adjacent battery pack 10, so as to make the household solar storage device more beautiful.

[0049] Please refer to Figure 2 and Figure 7 Furthermore, the side walls of the battery pack 10 are provided with an annular protrusion 11 and a limiting groove 12 on both sides along the stacking direction, and the limiting groove 12 of one battery pack 10 can be sleeved on the outer periphery of the annular protrusion 11 of another battery pack 10. The snap-on button 20 is provided on the side wall of the annular protrusion 11, and the snap-on hole 30 is provided on the groove wall of the limiting groove 12. In this way, two adjacent battery packs 10 are sleeved on each other. After the two are fixed, only the snap-on hole 30 and one end of the snap-on button 20 snapped to the snap-on hole 30 can be seen on the outer periphery of the household photovoltaic storage device, and other structures are completely hidden, thereby improving the aesthetics of the household photovoltaic storage device.

[0050] Specifically, the shortest distance between the outer wall surface of the annular protrusion 11 and the outer wall surface of the battery pack 10 is equal to the thickness of the groove wall of the limiting groove 12, so that after the limiting groove 12 is sleeved on the annular protrusion 11, the outer wall surfaces of the two battery packs 10 fit together so that the outer wall surfaces of both are in the same plane.

[0051] Optionally, when the snap-in button 20 is in the second working position, the end of the snap-in button 20 away from the battery pack 10 will not protrude from the outer wall of the battery pack 10, thereby ensuring the smoothness of the outer wall of the household photovoltaic storage device without any protruding structure, thereby improving the aesthetics.

[0052] Optionally, the inner wall surface of the annular protrusion 11 is provided with a boss 111, and the snap-in button 20 is arranged on the boss 111, so that after the two battery packs 10 are installed, multiple structures of the snap-in button 20 can be hidden, thereby improving the aesthetics of the household solar storage device.

[0053] Furthermore, a guiding slope (not shown in the figure) is provided on the side of the groove wall of the limiting groove 12 facing the other battery pack 10. The guiding slope means that the wall thickness of the groove wall of the limiting groove 12 facing the other battery pack 10 gradually decreases from the side close to the battery pack 10 to the side away from the battery pack 10, and it has a certain guiding effect. When two battery packs 10 are installed, the snap-in button 20 is in the second working position. When the battery pack 10 is docked with another battery pack 10, the guiding bevel first abuts against the end of the snap-in button 20 away from the battery pack 10. Then, as the two battery packs 10 gradually approach each other, under the guiding action of the guiding bevel, the end of the snap-in button 20 away from the battery pack 10 is abutted by the groove wall of the limiting groove 12, and the snap-in button 20 is gradually pushed to the first working position until the two battery packs 10 are stacked. The snap-in button 20 is opposite to the snap-in hole 30 and is no longer compressed by the groove wall of the limiting groove 12. It returns to the second working position, thereby realizing automatic snap-in of the two battery packs 10. There is no need for the operator to perform multiple operations, which is quick and convenient, saving time and effort.
