Description

Technical Field

[0001] The present disclosure relates to the field of battery energy storage equipment, and in particular to a battery module bracket. Background Art

[0002] The rack-type battery module bracket is a device specially designed to support and fix the battery module. It is usually made of metal material. It adopts a rack structure and can be fixed on the equipment to effectively support the battery module. This bracket not only has sufficient strength and rigidity to withstand the mass and external impact of the battery module, but also facilitates the installation and removal of the battery module, providing convenience for equipment maintenance and battery replacement. At present, in the battery module bracket, multiple battery packs or battery packs are installed in layers from top to bottom. Since the weight of a single battery pack or battery pack is about 600 kilograms, the installation and removal of heavier battery packs or battery packs require the assistance of special tools or tooling, which reduces the installation efficiency; and the fixing method of the battery module bracket may not be strong enough, causing the battery module to fall off or shake during use, which will affect the stability and safety of the equipment.

[0003] According to the search, in the prior art, for example, patent CN202320353576.0 discloses a battery rack for energy storage equipment, the battery rack includes two mounting brackets, the mounting brackets include multiple first support beams for supporting the battery pack and second support beams for fixing the first support beams; the battery pack mounting position is formed between two first support beams at the same height on the two mounting brackets; each first support beam is provided with a sliding device for cooperating with the battery pack, the battery pack can be transported to the battery pack mounting position by sliding installation, and the positioning is achieved by the limit device provided on the mounting bracket. The battery rack of the above energy storage equipment also has the following defects in practical applications:

[0004] Firstly, a sliding device and a guide block with a T-shaped cross-section are provided on the first support beam. The addition of the device and the guide block on the support beam may increase the weight borne by the support beam, and the manufacturing and installation costs are high, and the difficulty of maintenance and repair is also increased; and due to the sliding characteristics of the sliding device, the battery module may shake or become unstable during installation and use, affecting the stability and safety of the equipment.

[0005] Secondly, the limiting device includes a limiting part and a locking part. The limiting part is used to limit the sliding of the battery pack, and the locking part is used to lock the position of the battery pack after it is installed on the first support beam. This requires components to be set at both ends of the first support beam to limit and fix the battery pack. For the installation and removal of each battery pack, the limiting part and the locking part need to be operated separately. The operation process may be cumbersome, reducing the efficiency of installing and replacing the battery pack. If the installation of the limiting part and the locking part is not reasonable, the battery pack may shake or fall off during use, affecting the stability and safety of the equipment.

The bracket assemblies are arranged on the columns 20, and the bracket assemblies can be fixedly connected to the columns 20 by bolts;

[0037] Each bracket assembly has two sliding mechanisms 30 that are relatively arranged. The sliding mechanisms 30 include a support plate 301, an upper baffle plate 302, a connecting plate 303 and a limiting plate 304. The connecting plate 303 is connected to the column 20.

[0045] The convex structure 3031 is made of elastic material and is used to resist the side of the battery module 10; the convex structure 3031 is made of elastic material, so that the convex structure 3031 has elastic force, and can resist the battery module 10 through the elastic force, and then clamp the battery module 10 from both sides; or a spring can be optionally set inside the convex structure 3031 to make it have elastic force, and then it can also resist the battery module 10 through the elastic force.

[0046] Furthermore, in this embodiment, a plurality of protruding structures 3031 are arranged on the connecting plate 303 from the opening end to the limiting plate, and the guide limiting assembly needs to be arranged to avoid the column 20 .

[0047] Furthermore, in the present embodiment, a plurality of columns 20 are arranged at intervals along the width direction on both sides of the battery module 10, and the plurality of columns 20 on both sides correspond to each other one by one; the number of arranged columns 20 is selected according to the width of the battery module 10, and then a suitable spacing between adjacent columns 20 is selected, so that the sliding mechanism 30 can be more stably connected to the columns 20, thereby avoiding the instability of the sliding mechanism 30 connected to the columns 20 due to a small number of columns 20.
