Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] Please see Figure 1-2 This utility model provides a stackable modular household handcart energy storage device, including a handcart board 1. Several support plates 3 are fixedly connected to the top of the handcart board 1. Several energy storage device boxes 2 are stacked on top of each support plate 3. Several lower connecting ears 9 are symmetrically fixedly connected to the two sides of the lower part of the energy storage device box 2, and several upper connecting ears 10 are symmetrically fixedly connected to the two sides of the upper part of the energy storage device box 2. The number of lower connecting ears 9 and upper connecting ears 10 is equal, and each lower connecting ear 9 corresponds to each upper connecting ear 10. A turntable 11 is threaded through and threadedly connected to the lower connecting ear 9. A threaded shaft 12 is fixedly installed at the lower end of the turntable 11, and a hexagonal groove 13 is opened at the upper end of the turntable 11. A threaded hole 14 matching the threaded shaft 12 is opened on the upper connecting ear 10.

[0022] In this technical solution, by placing one energy storage device box 2 on top of another energy storage device box 2, aligning the corresponding lower connecting ear 9 with the upper connecting ear 10, and then inserting an Allen wrench into the hexagonal groove 13 and rotating the turntable 11, the lower end of the threaded shaft 12 is screwed into the corresponding threaded hole 14, thus completing the stacking and fixing of the two energy storage device boxes 2, realizing the stacked modular function. Multiple energy storage device boxes 2 can be stacked according to actual needs, making it flexible and convenient to use.

[0023] In some technical solutions, such as Figure 1 and Figure 4 As shown, L-shaped parts 4 are fixedly connected to the four corners of the bottom of the handcart plate 1. A threaded shaft 16 is threaded through and connected to the L-shaped parts 4. A grinding disc 17 is fixedly installed at the lower end of the threaded shaft 16, and a handwheel 18 is fixedly installed at the upper end of the threaded shaft 16.

[0024] In use, rotating the handwheel 18 drives the threaded shaft 16 to rotate, and the threaded shaft 16 drives the grinding disc 17 to move downward, so that the grinding disc 17 contacts the ground, thus ensuring the anti-slip properties of the handcart energy storage device when it is placed.

[0025] In some technical solutions, such as Figure 1-3 As shown, the support plate 3 has several threaded holes 15 that match the threaded shaft 12, and the lower ends of all the threaded shafts 12 are located inside the corresponding threaded holes 15.

[0026] In use, by aligning the lower connecting lugs 9 on the bottom energy storage device box 2 with the threaded holes 15 on the support plate 3, and using an Allen wrench and hexagonal groove 13 to screw the lower end of the threaded shaft 12 into the corresponding threaded hole 15, the connection between the bottom energy storage device box 2 and the support plate 3 can be completed, ensuring the stability of the stacked energy storage device boxes 2.

[0027] In some technical solutions, such as Figure 1-2 As shown, a matching baffle 5 is fixedly connected to the top of the energy storage equipment box 2.

[0028] During use, the baffle 5 can prevent two energy storage device boxes 2 from directly contacting each other, thus preventing the stacked energy storage device boxes 2 from affecting their own heat dissipation effect.

[0029] In some technical solutions, such as Figure 1 As shown, casters 8 are installed at the four corners of the bottom of the handcart board 1.

[0030] When in use, the swivel wheels 8 at the four corners of the bottom of the handcart 1 facilitate the movement of the energy storage device.

[0031] In some technical solutions, such as Figure 1 As shown, L-shaped rods 6 are fixedly connected to the front and rear of one side of the handcart board 1, and a handle 7 is fixedly installed between the two L-shaped rods 6.

[0032] When in use, the movement direction of the handcart energy storage device can be easily controlled by the handle 7 between the two L-shaped rods 6.

[0033] Working principle: During installation, align the lower connecting lugs 9 on the bottom energy storage device box 2 with the threaded holes 15 on the support plate 3. Insert the Allen wrench into the hexagonal groove 13 and rotate the turntable 11 to screw the lower end of the threaded shaft 12 into the corresponding threaded hole 15. This completes the connection between the bottom energy storage device box 2 and the support plate 3. Place one energy storage device box 2 on top of another, aligning the corresponding lower connecting lugs 9 with the upper connecting lugs 10. Then, insert the Allen wrench... Insert the hexagonal groove 13 and rotate the turntable 11 to screw the lower end of the threaded shaft 12 into the corresponding threaded hole 14. This completes the stacking and fixing of two energy storage equipment boxes 2. Multiple energy storage equipment boxes 2 can be stacked according to actual needs. During use, when the trolley energy storage equipment is moved to the desired placement position, rotate the handwheel 18 to drive the threaded shaft 16 to rotate. The threaded shaft 16 drives the sanding disc 17 to move downward, so that the sanding disc 17 contacts the ground, thus ensuring the anti-slip performance of the trolley energy storage equipment when it is placed.
