[0002] With the widespread application of renewable energy and the development of smart home technology, home energy storage systems have become an important means to improve energy self-sufficiency and optimize electricity usage efficiency. Currently, most home energy storage battery stacking solutions on the market use a direct stacking method, where battery modules are physically placed simply by increasing the contact area. This lacks an effective fixing mechanism, making directly stacked batteries prone to collapse and damage when subjected to external forces (such as handling). Therefore, we propose an improvement: a home energy storage battery stacking device. Utility Model Content

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0024] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0026] For an example, please refer to... Figures 1-5 A household energy storage battery stacking device includes several battery modules 1 stacked together, with the bottom of the lowest battery module 1 connected to a base plate 2. The top of the base plate 2 is provided with a limiting structure 3, which includes a limiting member installed on the top of the base plate 2. Several limiting frames 311 are sleeved on the outer surface of the limiting member. The several limiting frames 311 are respectively connected to several battery modules 1. The limiting frames 311 and the battery modules 1 are connected by bolts. The base plate 2 and the lowest battery module 1 are also connected by bolts.

[0027] Furthermore, the limiting component includes a column 301 fixedly installed on the top of the base plate 2. The side of the column 301 is provided with a plurality of first side grooves 302. The inner walls of the plurality of first side grooves 302 are all inserted with side plates 304. The top ends of the plurality of side plates 304 are fixedly connected with a top plate 306 located above the column 301. The column 301 is welded to the top of the base plate 2, and the top plate 306 is welded to the side plates 304.

[0028] Furthermore, several limiting frames 311 are fitted onto the outer surfaces of the column 301 and the side plate 304 to form a limiting function.

[0029] Furthermore, a hand-tightening screw 310 is rotatably connected to the top plate 306 via a bearing, and a threaded groove is provided in the middle of the column 301, with the hand-tightening screw 310 threadedly connected to the inner wall of the threaded groove.

[0030] Furthermore, one of the side plates 304 has a threaded opening 307, and a threaded rod 308 is threadedly connected to the inner wall of the threaded opening 307. One end of the threaded rod 308 passes through the uppermost limiting frame 311 and is fixedly connected to a handle 309. The threaded rod 308 and the handle 309 are welded together.

[0031] Furthermore, the grip 309 is parallel to the side of the battery module 1 near the side plate 304. When the whole unit needs to be moved, the grip 309 can be used by the user's hand to apply pushing and pulling force.

[0032] Furthermore, an auxiliary component is provided between the side plate 304 and the first side groove 302; the auxiliary component includes a second side groove 305 opened on the side of the side plate 304 and a first limiting plate 303 fixedly connected to the inner wall of the first side groove 302. The first limiting plate 303 is inserted and connected to the inner wall of the second side groove 305. The column 301, the first side groove 302 and the first limiting plate 303 are integrally formed by extrusion process.

[0033] Furthermore, several wheels 201 are installed at the bottom of the base plate 2. The wheels 201 are fuma wheels, also known as horizontal adjustment support wheels or heavy-duty horizontal adjustment casters. They are a special type of caster that combines movement and fixation functions. The fuma wheels can quickly switch between "moving mode" and "fixed mode" by rotating the adjustment block base. During transportation, the moving wheels are in contact with the ground for easy pushing. After being in place, rotating the adjustment block makes the base support the ground, reducing the overall slippage.

[0034] Battery module 1 is an existing component, and its specific structure and stacking connection principle are existing technologies, which will not be described in detail in this application.

[0035] Place the bottom battery module 1 on the base plate 2 and fix it to the base plate 2 with bolts. Turn the hand screw 310 and adjust the top plate 306 to a suitable height according to the number of battery modules 1 stacked, ensuring that the limiting frame formed by the column 301 and the side plate 304 is stable. Fit the limiting frame 311 on the outer surface of the column 301 and the side plate 304. Each battery module 1 corresponds to one limiting frame 311. Fix the two together with bolts. Stack the remaining battery modules 1 in the same way. Turn the handle 309 to connect the threaded rod 308 with the threaded opening 307 to complete the overall fixation. When disassembling, turn the handle 309 to separate the threaded rod 308 from the threaded opening 307 to release the overall fixation. Pull the battery module 1 upward to remove the battery module 1.
