[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] This utility model provides a technical solution: a battery system structure, including a housing 1 and a battery pack, the battery pack being located inside the housing 1. The housing 1 contains several vertically arranged module fixing structures 2. The battery pack includes end plates 3, side plates 4, and several sequentially arranged batteries 5. The side plates 4 are connected to the module fixing structures 1 for fixing the battery pack. Figure 1 The module fixing structure 2 is a stepped staggered structure when the battery pack inside the box 1 is three-layered. When the battery pack inside the box 1 needs to be installed in three layers, the corresponding module fixing structure 2 is three layers. Each step corresponds to the connection position of the upper side plate 4 of the same layer of battery pack, thereby maximizing the use of the battery pack installation space and meeting the needs of high-density battery pack arrangement in a small space.

[0020] Furthermore, in order to improve the tightness of the connection between the module fixing structure 2 and the housing 1, the spacing and arrangement of the module fixing structure 2 on the inner wall of the housing 1 are adapted to the installation spacing of the battery pack.

[0021] like Figure 2-3 When the battery pack inside the housing 1 is installed as a two-layer battery pack, a connecting plate 6 is provided on one side of the side plate 4. The connecting plate 6 is connected to the module fixing structure 2. The corresponding module fixing structure 2 has two steps, and each step is provided with a threaded hole 8. The connecting plate 6 is provided with a through hole 9 corresponding to the position of the threaded hole 8. By passing a bolt through the through hole 9 on the connecting plate 6 and threading it into the threaded hole 8, the connecting plate 6 and the corresponding step surface in the module fixing structure 2 are tightly connected, thereby improving the stability of the connection between the two.

[0022] To further improve the tightness of the connection between the connecting plate 6 and the module fixing structure 2, the size of the connecting plate 6 on each battery pack is adapted to the spacing size of the corresponding module fixing structure 2.

[0023] To ensure the deformation resistance of the connecting plate 6, the connecting plate 6 is made of a material with deformation resistance.

[0024] To improve the connection strength of the connecting plate 6, a reinforcing rib 7 is provided between the connecting plate 6 and the side plate 4.

[0025] This utility model, through the design of the module fixing structure 2, meets the battery pack installation requirements while maximizing the use of the space inside the housing 1, making it particularly suitable for application scenarios with limited space and requiring a high level of protection. The reinforced design of the connecting plate 6 improves the stability of the structure and avoids the battery pack from loosening or shifting due to external vibrations or other factors during use, greatly improving the safety and stability of the battery system during use.

[0026] The parts of the utility model not described in detail are prior art. Although embodiments of the utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the utility model.
