Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 The utility model provides a technical solution: a stacked high-voltage household energy storage device, comprising a plurality of module outer frames 100 arranged in a stacked manner, wherein the plurality of module outer frames 100 are arranged at equal intervals from top to bottom, a top cover 200 is arranged above the topmost module outer frame 100, and battery separators 500 are arranged above the other groups of module outer frames 100;

[0023] The plurality of module outer frames 100 each include a rectangular frame 101, and rectangular through holes 105 are provided at four ends of the upper surface of the rectangular frame 101. A connecting component 400 is provided inside each set of rectangular through holes 105, and a limiting groove 107 and a clamping groove 106 for embedding the connecting component 400 are provided on one side of the inner cavity of the rectangular through hole 105;

[0024] The connecting component 400 includes a vertical plate 401, one side of which is fixedly connected with multiple groups of springs 404 that abut against the other side of the inner cavity of the rectangular through hole 105, the upper end of one side of the vertical plate 401 is fixedly connected with a block 402 that fits with the slot 106, and the lower end of one side of the vertical plate 401 is fixedly connected with a limit block 403 that is slidably inserted into the limit slot 107.

[0025] The thickness of the vertical plate 401 is smaller than the thickness of the rectangular through hole 105, and the length of the vertical plate 401 is smaller than the depth of the rectangular through hole 105. The limiting groove 107 is arranged above the card slot 106, which facilitates the vertical plate 401 to move inside the rectangular through hole 105, and then facilitates the compression of the spring 404 while allowing the card block 402 to disengage from the card slot 106, thereby facilitating the docking and separation of the stacked module frames 100.

[0026] The four end corners of the rectangular frame 101 are all set at flat angles, and a plurality of groups of protrusions 108 are fixedly connected to the upper surface of the rectangular frame 101. The lower surface of the rectangular frame 101 is provided with sockets for the plurality of groups of protrusions 108 to be plugged in. The flat angle setting improves the strength of the rectangular frame 101, thereby improving the overall strength and preventing the rectangular frame 101 from being deformed.

[0027] The battery separator 500 is mainly composed of a cover and a sealing frame, and the upper surface of the sealing frame is provided with round holes for the protrusions 108 to be inserted. The cover and the sealing frame are convenient for protecting the installed battery module, improving the protection effect and improving the fit between the rectangular frame 101 and the battery separator 500.

[0028] The height of the top cover 200 is greater than the height of the battery separator 500 , and the tops of multiple groups of battery separators 500 are all attached to the lower surface of the rectangular frame 101 , which is convenient for protecting the battery module and improving the safety of the battery module installed in the module outer frame 100 .
