[0002] With the increasing development of new energy vehicles, in order to meet the energy and voltage requirements of electric vehicles, their power battery systems consist of one or more battery packs. Generally speaking, each battery pack consists of several battery modules, and each battery module consists of several individual cells. Typically, several individual cells are connected in series and parallel to form a battery module, and then multiple batteries are integrated using a battery module frame to form a complete battery module.

[0003] However, existing battery module frames, in order to save internal space and thus increase battery module capacity, tightly fit multiple batteries together. This leads to accelerated heat buildup during rapid or overcharging, especially under direct sunlight or poor ventilation. Therefore, there is an urgent need to develop battery module frames and battery modules to meet practical application needs. Utility Model Content

[0006] The battery module frame includes two mounting bases and several fixed frames. The fixed frames are vertically arranged around the mounting bases, and the top and bottom ends of the fixed frames are fixedly connected to the corresponding mounting bases. A cavity that can accommodate multiple batteries is formed between the two mounting bases. Several limiting gaskets are provided inside the cavity. The limiting gaskets are hollow and have clearance grooves inside. The limiting gaskets are horizontally arranged inside the cavity. The cavity is divided into several fixed cavities by the limiting gaskets.

[0007] As a further solution, one end face of the limiting gasket is provided with a guide groove. The guide groove has a downwardly recessed structure, and the two ends of the guide groove are respectively opened on the inner edge and outer edge of the limiting gasket. The clearance groove forms a conductive structure with the outside through the guide groove.

[0008] As a further solution described above, the limiting gasket is a rectangular structure, and the clearance groove is consistent with the limiting gasket and is a rectangular empty groove structure.

[0009] As a further embodiment of the above description, the guide groove is an arc-shaped groove, and several limiting pads are arranged in a linear array along the vertical direction inside the cavity.

[0010] As a further solution described above, the fixed frame is a long strip structure, and the ends of the fixed frame are threadedly connected to the edge of the fixed seat by fixing bolts.

[0011] As a further solution described above, the mounting base is provided with reinforcing ribs inside, and the cross-sectional structure of the reinforcing ribs is a multi-segment broken line shape.

[0012] The battery module includes the aforementioned battery module frame and several battery cells. The battery cells are respectively embedded in a fixed cavity. Adjacent battery cells are spaced apart by limiting spacers, and a heat-conducting cavity is formed between adjacent battery cells at the clearance slot.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: Several limiting pads are horizontally arranged inside the cavity, and the cavity is divided into several fixed cavities by the limiting pads. The batteries are respectively embedded in the fixed cavities. Adjacent batteries are separated by limiting pads, and a heat-conducting cavity is formed between adjacent batteries at the clearance groove. At the same time, the conductive grooves opened in the limiting pads facilitate the flow of heat to the outside of the battery module, which enhances the heat dissipation capacity of the battery module. Meanwhile, the limiting pads reduce the heat transfer between batteries through direct contact. Attached Figure Description
