Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery technology, specifically to a module connection component. Background Technology
[0002] The market demand for high-capacity batteries is increasing daily. To achieve greater battery capacity, in addition to increasing the size and energy density of the cells, it is also necessary to continuously optimize the existing space dimensions and internal layout of the storage box. Traditional energy storage boxes typically use a single-row, multi-module arrangement, while CCS modules generally have mounting holes designed on the metal endplate of the module in a single row. However, when developing larger capacity energy storage boxes, in addition to increasing the size and energy density of the cells, a multi-row, multi-module arrangement is required. When sampling the cell voltage and temperature information of the cells in the rear row of modules, it is necessary to cross the front row of modules and add additional fixing points. Existing connectors do not have adapter mounting points on the endplate, making it impossible to fix the adapter during use. Developing a new metal endplate for the module would increase the design and development mold costs and require additional time for stability testing of the new module, increasing the consumption of manpower and resources. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of the prior art by proposing a module connection component that does not require the development of new connection components, but can meet the needs of multi-row, multi-module applications by improving the existing connection components.

The fixed bracket is disposed at the end of the battery pack, the fixed end plate is disposed between the fixed bracket and the battery pack, the connecting strip extends along the length of the battery pack, and its end is disposed on the fixed end plate. The top of the fixed bracket is provided with a mounting plate, and the mounting plate is provided with a fixing member. The adapter strip is disposed on the fixed bracket through the fixing member. The connecting strip and the adapter strip are arranged in pairs.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.
[0025] Please see Figures 1 to 5A module connection assembly is used for connecting battery cells within a multi-row, multi-module battery pack to collect cell operating information. It includes paired connection bars 11 and adapter bars 12, a fixing bracket 20, and a fixing end plate 30. The fixing bracket 20 is located at the end of the battery pack, and the fixing end plate 30 is located between the battery pack and the fixing bracket 20. The connection bars 11 are arranged along the length of the battery pack and are connected to the fixing bracket 20 via the fixing end plate 30. A fixing member 40 is provided at the top of the fixing bracket 20, and the end of the adapter bar 12 is connected to the fixing bracket 20 via the fixing member 40.
[0026] The fixed bracket 20 is used to fix and support the connecting row 11 and the transition row 12. In this embodiment, the fixed bracket 20 is a long plate that is vertically arranged. Several mounting plates 21 are provided on its top. The mounting plates 21 are evenly arranged along the length of the fixed bracket 20. The connecting row 11 and the transition row 12 are arranged in pairs on the mounting plates 21 along the fixed bracket 20.
[0027] The fixed end plate 30 is connected to the fixed bracket 20 via the mounting plate 21. Specifically, the mounting plate 21 is perpendicular to the fixed bracket 20 and extends into the battery pack relative to the fixed bracket 20 to support the connecting bar 11 and the adapter bar 12. The fixed end plate 30 has mounting holes 32 at both ends of its top, and the mounting plate 21 has fixing holes 212. When the fixed end plate 30 is connected to the fixed bracket 20, the top surface of the fixed end plate 30 connects to the bottom of the mounting plate 21, with the mounting holes 32 corresponding to the fixing holes 212. The fixed end plate 30 is then fixed to the fixed bracket 20 using bolts. The mounting plate 21 connects the fixed end plate 30 to the fixed bracket 20 at the top, so that the fixed end is located inside the fixed bracket 20, with a small gap between it and the fixed bracket 20. This gap can be used for subsequent filling of the battery pack with insulating material and cooling components.
[0028] In this embodiment, the mounting plate 21 is formed by bending the top of the fixing plate.
[0029] In a multi-row, multi-module arrangement, multiple sets of connecting rows 11 and transition rows 12 are arranged along the length of the fixing bracket 20. The mounting plate 21, located in the middle of the fixing bracket 20, needs to connect both fixed end plates 30 and the transition row 12 in the previous set simultaneously. To avoid interference between the connection between the fixed end plate 30 and the mounting plate 21, and between the transition row 12 and the mounting plate 21, in this application, the transition row 12 is connected to the mounting plate 21 via a fastener 40. The fastener 40 includes a first connecting surface 41 and a second connecting surface 42. The first connecting surface 41 is located above the second connecting surface 42 and is used to connect the transition row 12. The second connecting surface 42 is used to connect the mounting plate 21, and the mounting plate 21 has a connecting hole 211. When the fastener 40 connects to the fixing bracket 20, the second connecting surface 42 is in contact with the top surface of the mounting plate 21, and a bolt is installed in the connecting hole 211 to fix the mounting plate 21 to the second connecting surface 42.
[0030] When the adapter 12 is connected to the mounting plate 21 via the fastener 40, the first connecting surface 41 is located above the mounting plate 21, and there is a gap between the first connecting surface 41 and the mounting plate 21. This gap can be used to accommodate the locking device, such as a nut, between the fixed end plate 30 and the mounting plate 21.
[0031] Both the adapter strip 12 and the connecting strip 11 are provided with adapter sockets 13 at one end of the connecting bracket 20. Preferably, the top of the fixed end plate 30 is provided with a raised mounting platform 31, which is located between two mounting holes 32. The end of the connecting strip 11 is connected to the mounting platform 31. The mounting platform 31 is used to raise the installation position of the connecting strip 11 so that when the connecting strip 11 is connected to the fixed bracket 20 through the fixed end plate 30, the end of the connecting strip 11 and the end of the adapter strip 12 are at the same height, so that the sockets 13 on the connecting strip 11 and the sockets 13 on the adapter strip 12 are at the same height, which facilitates the subsequent connection of the battery pack wiring harness.
[0032] Preferably, a recessed groove is provided on the top of the fixing bracket 20 between two adjacent mounting plates 21 to reduce the weight of the fixing bracket 20 and reduce production costs.
[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
