Description

Technical Field

[0001] This utility model relates to the field of energy storage power technology, and in particular to a household energy storage power supply. Background Technology

[0002] Energy storage batteries are devices that store electrical energy and release it when needed. They are widely used in renewable energy, grid peak shaving, electric vehicles, and home energy storage.

[0003] Chinese patent application CN202310727729.8 discloses an energy storage nano-silicon battery. This battery, by controlling the amount of silicon dioxide used, produces an emulsion-like electrolyte through high-speed shear dispersion in an emulsifier, resulting in good fluidity and easy filling. By adjusting the amounts of metal sulfate and sodium carboxymethyl cellulose, the filled battery exhibits excellent low-temperature discharge capacity, low-temperature starting capability, and cycle durability. It does not hydrate or stratify during use and demonstrates good stability. However, the battery's terminal block lacks an insulating structure for support. When the terminal block expands due to heat after being energized, it can easily contact the battery casing, leading to leakage. Adding an insulating material to the terminal block would hinder heat dissipation and shorten its lifespan. Utility Model Content

[0004] The main objective of this invention is to provide a household energy storage power supply to solve the problems raised in related technologies.

[0005] To achieve the above objectives, according to one aspect of this utility model, a household energy storage power supply is provided, comprising a housing and a battery body disposed within the housing. Two terminal blocks are fixedly disposed at the end of the battery body. Each terminal block is fitted with a plurality of insulating portions, which are made of insulating material and serve to separate the terminal blocks from the housing. The two terminal blocks are respectively connected to the positive and negative terminals of the battery body.

[0006] Furthermore, the outer casing includes a lower casing, an upper casing, a left casing, and a right casing, which are fixed together by screws.

[0007] Furthermore, a handle is fixedly provided on the top of the upper housing.

[0008] Furthermore, the isolation part includes a sleeve made of elastic material, which is sleeved on the terminal block.

[0009] Furthermore, the sleeve is provided with several through-holes for heat dissipation.

[0010] Furthermore, several support blocks are fixedly provided on both the front and rear sides of the sleeve.

[0011] Furthermore, the support block is provided with a through-hole for weight reduction.

[0012] Furthermore, a support rod passes through the weight-reducing hole.

[0013] Furthermore, an isolation block is fixedly provided at the outer end of the support block.

[0014] Furthermore, one end of the support rod is fixedly connected to the support block, and the other end is fixedly connected to the isolation block.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This invention supports the terminal block by setting an isolation section, preventing the terminal block from contacting the outer casing due to external factors such as vibration, which could cause battery leakage. The segmented sleeve occupies only a small part of the outer surface of the terminal block, having little impact on its heat dissipation. The heat generated by the terminal block can be directly dissipated through its surface. Because the volume of the terminal block expands little due to heat, it will not contact the outer casing, thus avoiding battery leakage. The segmented isolation section has little impact on the heat dissipation of the terminal block, and therefore will not shorten its service life. Attached Figure Description

[0023] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0024] This embodiment provides a household energy storage power supply, such as... Figure 1 As shown, the battery includes an outer casing and a battery body 6 disposed within the casing. Two terminal blocks 7 are fixedly mounted on the ends of the battery body 6. Each terminal block 7 is fitted with several insulating parts 8, which are made of insulating material and are used to separate the terminal blocks 7 from the outer casing. The two terminal blocks 7 are respectively connected to the positive and negative terminals of the battery body 6.

[0025] like Figure 2 As shown, the outer casing includes a lower casing 1, an upper casing 2, a left casing 3, and a right casing 4, which are fixed together by screws. The screw-fixed lower casing 1, upper casing 2, left casing 3, and right casing 4 allow for easy disassembly and inspection of the internal structures of the casing.

[0026] A handle 5 is fixedly provided on the top of the upper shell 2 for easy carrying.

[0027] like Figure 3 As shown, the isolation part 8 includes a sleeve 81, which is a rubber sleeve with a certain elasticity. The sleeve 81 can be tightly fitted onto the terminal block 7 and will not slide on the terminal block 7, thus maintaining the isolation part 8 in a preset insulating isolation position and supporting the terminal block 7.

[0028] The sleeve 81 is provided with several through-holes 82 for heat dissipation. The heat generated by the terminal block 7 is dissipated through the heat dissipation holes 82 and air convection, effectively reducing its operating temperature.

[0029] Several support blocks 83 are fixedly provided on both the front and rear sides of the sleeve body 81.

[0030] The support block 83 is provided with a through-hole 84 for weight reduction. The through-hole 84 can reduce the weight of the support block 83, prevent the support block 83 from deforming and sagging due to its own weight, ensure its support distance is stable, and prevent the terminal block 7 from contacting the housing.

[0031] A support rod 85 passes through the weight reduction hole 84.

[0032] An isolation block 86 is fixedly provided at the outer end of the support block 83. The isolation block 86 increases the contact area between the support block 83 and the shell, thereby increasing the support stability of the support block 83. The sleeve 81 itself has sufficient toughness to horizontally and stably fix the support block 83, support rod 85 and isolation block 86 on it.

[0033] One end of the support rod 85 is fixedly connected to the support block 83, and the other end is fixedly connected to the isolation block 86. The support rod 85 increases the support strength of the support block 83, further increasing the support stability of the support block 83.

[0034] When current flows through the terminal block 7, it begins to heat up and expand. Contact between the energized terminal block 7 and the outer casing will generate a short-circuit current, posing a risk of leakage. The sleeve 81 is fitted onto the terminal block 7, and the support block 83 extends horizontally to isolate the terminal block 7 from the outer casing, preventing the terminal block 7 from contacting the casing due to vibration or other external factors, thus preventing battery leakage.

[0035] The segmented housing 81 occupies only a small portion of the outer surface of the terminal block 7, thus having little impact on its heat dissipation. The heat generated by the terminal block 7 can be directly dissipated through its surface. Because the volume of the terminal block 7 is small due to thermal expansion, it will not come into contact with the outer casing, thereby avoiding battery leakage.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
