Description

Technical Field

[0001] The utility model relates to the technical field of battery modules, in particular to a bracket structure with reserved expansion space for battery cells. Background Art

[0002] In traditional battery components, the battery cell bracket is often one of the key components of the entire component structure. However, since the battery cells may expand during charging and discharging, the traditional separator cannot release the bulging force of the battery cells, resulting in deformation of the overall size of the module or failure of the structural parts.

[0003] Therefore, it is necessary to design a bracket structure with reserved expansion space for battery cells to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a bracket structure with reserved expansion space for battery cells to overcome the above-mentioned deficiencies existing in the current prior art.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A bracket structure with reserved expansion space for battery cells, which includes a plurality of bracket bodies stacked and installed in sequence, battery cells placed between the bracket bodies, and an end plate arranged on the first battery cell. It is characterized in that: the bracket body includes a frame and a partition plate placed in the middle of the frame. An empty groove is opened in the middle of the partition plate, grooves are opened at both the upper and lower ends of the frame, and brackets for supporting the battery cells extend outward from the left and right sides at the lower end of the frame.

[0007] Preferably, the brackets, battery cells, and end plate are fixed together by a packing strap.

[0008] Preferably, at least two layers of packing straps are provided.

[0009] The beneficial effect of the utility model is that: in this technical solution, an empty groove is opened in the middle of the partition plate to provide space for the expansion of the battery cells, thereby effectively reducing the excessive deformation of the module size caused by the bulging of the battery cells. At the same time, grooves and brackets are provided to ensure the integrity of the battery cells after stacking, and the integrity of the battery module is enhanced by bundling with straps.

[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0015] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0016] Refer to Figures 1 to 3 , a bracket structure with reserved expansion space for the battery cell, which includes a plurality of bracket bodies 1 stacked and installed in sequence, a battery cell 2 placed between the bracket bodies, and an end plate 3 provided on the first battery cell;

[0017] In order to effectively fix the bracket, the battery cell and the end plate together, the bracket, the battery cell and the end plate are fixed by a packing belt 4, and at least two layers of packing belts 4 are provided to fix the upper half and the lower half respectively;

[0018] The bracket body 1 includes a frame 11 and a partition 12 placed in the middle of the frame; an empty slot 13 is opened in the middle of the partition; the empty slot 13 provides space for the expansion of the battery cell, thereby effectively reducing the excessive deformation of the module size caused by the swelling of the battery cell;

[0019] Grooves 14 are opened at both the upper and lower ends of the frame, and the grooves are used to cooperate with the connecting pieces on the battery cell 2 for limitation. Two sets of frames are combined, and the grooves 14 at both ends limit the four sides of the connecting pieces of the battery cell respectively, which not only plays the role of installation but also plays the role of limitation;

[0020] In order to effectively hold the battery cells and prevent them from falling off during the installation process, which may affect the installation effect, brackets 15 extend outward from the left and right sides at the lower end of the frame 11. The battery cells are placed on the brackets 15 and pushed inward, and the grooves 14 restrict the battery cells, thereby ensuring the integrity of the stacked battery cells. The integrity of the battery module is enhanced by bundling with straps.

[0021] The beneficial effects of the present utility model are as follows. By providing an empty slot in the middle of the partition board, space is provided for the expansion of the battery cells, effectively reducing the excessive deformation of the module size caused by the swelling of the battery cells. At the same time, grooves and brackets are provided to ensure the integrity of the stacked battery cells, and the integrity of the battery module is enhanced by bundling with straps.
