Description

Technical Field

[0001] The utility model relates to the technical field of energy storage batteries, and particularly refers to a pressing strip structure for locking batteries in an energy storage sheet metal box. Background Art

[0002] Energy storage batteries, usually referred to as energy storage cells, are devices that can store energy for later use. They play a crucial role in modern power systems and the field of renewable energy, especially in the context of the increasing popularity of solar and wind energy. The main goal of energy storage batteries is to solve the problem of energy supply-demand mismatch by storing excess energy for release during peak demand periods, ensuring the stability of the power grid and the efficient utilization of energy.

[0003] Energy storage batteries are widely used in multiple fields, such as the integration of renewable energy, grid regulation, electric vehicles, home energy storage systems, etc.

[0004] Currently, energy storage battery module products are mainly composed of batteries + BMS placed in a sheet metal box. Among them, many batteries use square aluminum shell batteries. After the batteries are installed, they need to be fixed in the sheet metal box. The tube positions are provided inside the sheet metal box in the front, back, left, and right directions, but the batteries still need to be pressed tightly in the up and down directions. Therefore, pressing strips are used for locking the batteries in the sheet metal box.

[0005] In the prior art, the structure of the pressing strip is as Figure 1 shown. This pressing strip structure is simple and prone to deformation. The module voltage acquisition wires are also not well arranged and are relatively messy. Content of the Utility Model

[0009] Furthermore, the inverted "U" - shaped structure is provided with cable tie fixing holes on the side walls connecting the fixed plate. Cable ties are passed through the cable tie fixing holes to fix the voltage acquisition wires inside the voltage acquisition wire storage hole, thereby effectively storing and fixing the voltage acquisition wires on the storage holes of the pressing strip structure, which is beautiful and generous.

[0010] Furthermore, positioning posts for installing the insulating board are arranged inside the fixing plate. The number of positioning posts is two or more, ensuring the safe fixation of the insulating package.

[0011] Furthermore, an insulating board is fixedly installed between the pressing strip structure and the battery. Both the battery and the insulating board are locked and fixed by the pressing strip structure, with good fixing effect, safety and reliability.

[0020] Second, good storage property. In the pressing strip structure of the present utility model, inverted "U" - shaped structures on both sides form voltage acquisition line storage holes, and the voltage acquisition lines are stored therein, realizing the effective collection of wiring and improving the aesthetics;

[0021] Third, simple and convenient. The pressing strip structure of the present utility model can be realized by adding inverted "U" - shaped structures on both sides on the basis of the existing pressing strip. The structure is simple and easy to process and form. Description of the Drawings
