[0037] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0038] Example 1:

[0039] Embodiment 1 of this application discloses a stacked residential energy storage system. (Refer to...) Figure 1 The system includes a main control box 1, an energy storage battery housing 2, and a chassis base 3. The main control box 1 contains an on / off circuit and a communication interface for controlling the operation of the entire energy storage system. The energy storage battery housing 2 houses the batteries, and the chassis base 3 supports the main control box 1 and the energy storage battery housing 2. The main control box 1, the energy storage battery housing 2, and the chassis base 3 are stacked sequentially. Multiple energy storage battery housings 2 are stacked between the main control box 1 and the chassis base 3.

[0040] Reference Figure 2 and Figure 3The energy storage battery housing 2 includes a battery base 21, and the chassis base 3 includes a chassis base 31. A top cover 110 is provided on both the battery base 21 and the chassis base 31. A slot 120 for inserting the top cover 110 is provided on both the main control box 1 and the battery base 21. The top cover 110 includes a battery cover 22 disposed on the battery base 21, the cross-sectional dimension of which is smaller than that of the battery base 21. The slot 120 includes a receiving groove 11 on the main control box 1 for accommodating the battery cover 22. The top cover 110 also includes a chassis cover 32 disposed on the chassis base 31, the cross-sectional dimension of which is smaller than that of the chassis base 31. The slot 120 includes a mounting groove 211 on the battery base 21 for accommodating the chassis cover 32. The main control box 1, battery base 21 and chassis base 31 have the same cross-sectional dimensions. The opening dimensions of the receiving slot 11 and the cross-sectional dimensions of the battery cover 22 are the same as the opening dimensions of the mounting slot 211, so that the main control box 1, multiple energy storage battery boxes 2 and chassis base 3 can be inserted and stacked.

[0041] Reference Figure 2 and Figure 3 A first connector 221 is fixedly installed on the side wall of the battery base 21 of the stacked main control box 1 or adjacent energy storage battery box 2. A second connector 212 for plugging and mating with the first connector 221 is fixedly connected to the side wall of the main control box 1 facing the battery cover 22. The second connector 212 is also fixedly connected to the side wall of the battery base 21 facing the battery cover 22 of the adjacent energy storage battery box 2. The second connector 212 is also fixedly connected to the side wall of the battery base 21 facing the chassis cover 32, so that the stacked main control box 1 and the energy storage battery box 2 and the stacked multiple energy storage battery boxes 2 can be electrically connected, and the stacked main control box 1 and the energy storage battery box 2 and the stacked multiple energy storage battery boxes 2 can be further limited in the horizontal direction.

[0042] Reference Figure 2 and Figure 3 The top cover 32 of the chassis has a clearance groove 321 on the side wall facing the stacked energy storage battery box 2. The clearance groove 321 is used for the insertion of the second connector 212 on the stacked energy storage battery box 2.

[0043] Reference Figure 3 and Figure 4 The chassis base 31 is a box-type structure with one open side, and the open side of the chassis base 31 faces the chassis top cover 32. A reinforcing rib 4 is fixedly installed in the inner cavity of the chassis base 31.

[0044] Reference Figure 1 Both the main control box 1 and the energy storage battery box 2 are equipped with nylon handles 10 on their side walls, making it convenient for users to disassemble and assemble the main control box 1 and the energy storage battery box 2.

[0045] The implementation principle of a stacked residential energy storage system in Embodiment 1 of this application is as follows: The user lifts the energy storage battery box 2 using the nylon handle 10 and stacks the energy storage battery box 2 on the chassis base 3. The side wall around the opening of the mounting groove 211 of the battery base 21 abuts against the side wall of the chassis base 31 around the chassis cover 32 of the chassis base 3, and the side wall of the mounting groove 211 abuts against the side wall of the chassis cover 32, thereby limiting the stacked energy storage battery box 2 and chassis base 3 in the horizontal direction. The user can select the number of stacked energy storage battery boxes 2 according to actual needs, and finally stack the main control box 1 on the topmost energy storage battery box 2. The stacking form between multiple energy storage battery boxes 2 and the stacking form between the main control box 1 and the energy storage battery box 2 are the same as the stacking form between the energy storage battery box 2 and the chassis base 3 described above.

[0046] Example 2:

[0047] Reference Figure 5 Unlike Embodiment 1, in this embodiment, the upper cover 110 is provided with a telescopic locking block 5, and the inner wall of the slot 120 is provided with a locking groove 213. The stacked main control box 1, energy storage battery box 2 and chassis base 3 are connected to the locking block 5 by the locking groove 213.

[0048] Reference Figure 5 and Figure 6 The following explanation uses the snap-fit ​​connection between the energy storage battery box 2 and the chassis base 3 as an example. A locking groove 311 is provided on the chassis top cover 32, extending horizontally. The locking groove 311 includes a large-diameter section 312 and a small-diameter section 313 communicating with the large-diameter section 312. The small-diameter section 313 is located on the side of the large-diameter section 312 away from the bottom wall of the locking groove 311 and communicates with the outside. A locking block 5 is slidably installed inside the large-diameter section 312 and the small-diameter section 313, sliding along the arrangement direction of the large-diameter section 312 and the small-diameter section 313. An elastic element 6 is press-fitted between the locking block 5 and the inner wall of the locking groove 311, extending and retracting in the direction that pushes the locking block 5 outward from the locking groove 311. The locking block 5 has an integrally formed limiting boss 9. The limiting boss 9 slides within the large diameter section 312. The cross-sectional dimension of the limiting boss 9 is larger than the cross-sectional dimension of the small diameter section 313 to prevent the locking block 5 from coming out of the locking groove 311.

[0049] Reference Figure 5 The battery base 21 has a slot 213 on its side wall. The slot 213 is used for inserting the card block 5 on the stacked energy storage battery box 2 to fix the energy storage battery box 2 and the chassis base 3 in the vertical direction.

[0050] Reference Figure 5 and Figure 6A handle 7 is rotatably mounted on the side wall of the battery base 21, and a transmission rod 8 is hinged to the handle 7. A hinge ear 71 is fixedly mounted on the handle 7, and a slotted hole 711 is opened on the hinge ear 71. The hinge shaft of the transmission rod 8 is rotatably and slidably mounted in the slotted hole 711. The transmission rod 8 is slidably mounted in the battery base 21 in a direction perpendicular to the movement direction of the locking block 5. A guide member 214 is fixedly mounted on the inner wall of the battery base 21. The transmission rod 8 passes through the guide member 214 and the bottom wall of the battery base 21 and is inserted into the locking groove 311 of the chassis base 31. The guide member 214 guides the movement direction of the transmission rod 8. Through holes are opened on the battery base 21, the chassis cover 32, and the chassis base 31 for the transmission rod 8 to pass through, so that the transmission rod 8 can extend into the chassis base 3.

[0051] Reference Figure 6 The locking block 5 has an unlocking groove 51 on the side wall facing the transmission rod 8. The inner wall of the unlocking groove 51 has an unlocking slope 52. The unlocking slope 52 is inclined in the direction that is further away from the bottom wall of the lock groove 311 and further away from the transmission rod 8. The unlocking slope 52 allows the transmission rod 8 to slide against it, so as to drive the locking block 5 back into the lock groove 311.

[0052] Reference Figure 6 The card block 5 has a retrieval slope 53 formed at an angle. The retrieval slope 53 is inclined in the same direction as the unlocking slope 52. The retrieval slope 53 is used for the side wall of the stacked energy storage battery box 2 to abut against it, so as to press the card block 5 back into the locking groove 311.

[0053] The implementation principle of a stacked residential energy storage system in Embodiment 2 of this application is as follows: When installing the energy storage system, the user lifts the energy storage battery box 2 using the handle 7 and stacks it on the chassis base 3. At this time, the side wall of the battery base 21 abuts against the retraction ramp 53 on the locking block 5 on the chassis base 3, pressing the locking block 5 back into the locking groove 311 until the energy storage battery box 2 is completely stacked on the chassis base 3. The elastic element 6 pushes the locking block 5 to move out of the locking groove 311, and the locking block 5 is inserted into the locking groove 213 on the energy storage battery box 2. If the energy storage system needs to be disassembled, the user lifts the energy storage battery box 2 using the handle 7. The handle 7 rotates and drives the transmission rod 8 to move towards the locking block 5. The transmission rod 8 slides against the unlocking ramp 52, causing the locking block 5 to retract into the locking groove 311. The locking block 5 disengages from the locking groove 213, thus unlocking. The user can then continue to lift the energy storage battery box 2 using the handle 7 to separate the energy storage battery box 2 from the chassis base 3. The disassembly and assembly methods between multiple energy storage battery boxes 2 and between the main control box 1 and the energy storage battery box 2 are the same as those between the energy storage battery box 2 and the chassis base 3.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
