Description

Technical Field

[0001] This application relates to the field of battery cluster installation, and particularly to a battery cluster support structure. Background Art

[0002] With the rapid development of the electrochemical energy storage battery industry, containerized energy storage technology is an important part of the new energy system. In the future, with the progress of technology and further cost reduction, containerized energy storage technology will play a more important role in the power system, providing strong support for the access of renewable energy and the stable operation of the power grid.

[0003] Currently, the structure of a containerized energy storage battery compartment consists of multiple battery clusters. Each battery cluster is composed of multiple battery packs and high-voltage boxes. The weights of the battery packs and high-voltage boxes vary from dozens of kilograms to hundreds of kilograms. Usually, the distance between the upper battery pack and the lower battery pack is only about 10 mm. The battery packs are often installed by pushing them in hard. However, this hard-pushing installation method wears off the anti-corrosion coating on the bottom of the battery pack and the corresponding installation bracket of the battery cluster, making it difficult to install the battery pack. At the same time, after the anti-corrosion coating of the bracket is worn off, the original anti-corrosion ability is reduced, resulting in the bracket being prone to rust, which in turn affects the outer shell of the battery pack. Summary of the Utility Model

[0004] In order to ensure the anti-corrosion ability of the bracket and reduce the possibility of bracket damage when installing the battery pack, this application provides a battery cluster support structure.

[0005] A battery cluster support structure provided by this application adopts the following technical solution:

The brackets are used to carry the battery packs. The sliding strips improve the strength of the brackets, prevent damage to the brackets when the battery packs are pushed in, and at the same time facilitate the battery packs to enter the space formed by the two-side brackets.

[0008] Preferably, a connecting component for positioning the bracket is provided on the side of the column facing the battery pack. The connecting component includes a supporting seat arranged on the column and a positioning member arranged on the column for positioning the bracket.

[0009] By adopting the above technical solutions, the connection component improves the stability of the bracket on the column. The support seat is used to support the bracket, and the positioning member is used to connect the bracket to the column.

[0010] Preferably, the positioning member includes a positioning bolt and a tongue provided on the bracket. A card slot for the tongue to be inserted into is formed on the column, and the positioning bolt is used to install the bracket on the column.

[0011] By adopting the above technical solutions, the positioning bolt installs the bracket on the column, and the tongue and the card slot further improve the connection stability between the bracket and the column.

[0012] Preferably, the bracket includes a connecting portion in contact with the column and a receiving portion provided at the bottom end of the connecting portion and used for receiving the battery pack. A wire tying block for positioning the battery pack harness is provided at one end of the receiving portion.

[0013] By adopting the above technical solutions, the connecting portion is used for connecting and installing with the column, the receiving portion is used for receiving the battery pack, and the wire tying block is used for tying various pipelines.

[0014] Preferably, the width of the feeding end of the connecting portion is larger than the width of the discharging end of the connecting portion.

[0016] Preferably, the sliding strip is made of a polymer material.

[0017] Preferably, fixing screws are provided on the sliding strip, and the fixing screws are used to install the sliding strip on the bracket.

[0018] By adopting the above technical solutions, the fixing screws improve the connection strength between the sliding strip and the bracket.

[0019] In summary, the supporting component is responsible for bearing the weight of the battery pack and the high-voltage box. The connection component improves the connection stability between the bracket and the column.

Detailed implementation manners

[0027] The following further Figures 1 - 6 describes the present application in detail with reference to the

[0028] An embodiment of the present application discloses a battery cluster bracket structure. Referring to Figure 1 and Figure 2 , it includes a first mounting seat 1, a supporting component 2 installed on both sides in the length direction of the first mounting seat 1 and used to position both sides of the battery pack 9, and a second mounting seat 3 installed on the top surface of the supporting component 2. The two sets of supporting components 2 are used to position the battery pack 9, facilitating the installer to sequentially place the battery pack 9 on the supporting component 2. The first mounting seat 1 and the second mounting seat 3 improve the stability at both ends of the supporting component 2. The first mounting seat 1 and the second mounting seat 3 have the same structure in the embodiment of the present application, both including two sets of mounting beams and keels located at both ends of the mounting beams. The supporting component 2 is installed on the mounting beams. In other embodiments, the first mounting seat 1 and the second mounting seat 3 can also be plate-like structures or grid-like structures.

[0029] Referring to Figure 3 and Figure 4The supporting assembly 2 includes a plurality of columns 21 fixedly mounted on the mounting seat 1 and arranged along the length direction of the mounting seat 1, and a plurality of brackets 22 arranged along the height direction of the columns 21. The two groups of supporting assemblies 2 are arranged opposite to each other, so as to facilitate the positioning of the parallel sides of the battery pack 9. In order to improve the strength of the bracket 22 and reduce the possibility of damaging the bracket 22 by pushing the battery pack 9, a slide bar 4 is installed on the bracket 22 along the length direction, and the slide bar 4 is installed on the side wall of the bracket 22 that receives the battery pack 9. The slide bar 4 is provided with a fixing screw 8, and the slide bar 4 is fixedly mounted on the bracket 22 by the fixing screw 8, so as to improve the stability of the slide bar 4 on the bracket 22. The slide bar 4 is made of a polymer material, which improves the wear resistance and surface smoothness of the slide bar 4.

[0030] Reference Figure 4 and Figure 5 In order to improve the connection strength between the column 21 and the bracket 22, a connecting component 5 for positioning the bracket 22 is installed on the column 21. The connecting component 5 includes a support seat 51 fixedly installed on the column 21 and used to support the bracket 22, and a positioning member 52 for positioning the bracket 22. The positioning member 52 includes a positioning bolt 521 and a tongue 522 fixedly installed on the bracket 22. The positioning bolt 521 fixes the bracket 22 on the column 21. The column 21 is provided with a slot 6 for the tongue 522 to be inserted into. When the tongue 522 on the bracket 22 is inserted into the slot 6, the positioning bolt 521 fixes the bracket 22 on the column 21, thereby improving the stability of the bracket 22 on the column 21.

[0031] Reference Figure 5 and Figure 6 In order to improve the supporting effect of the bracket 22 on the battery pack 9, the bracket 22 includes a connecting portion 221 and a receiving portion 222. The tongue 522 is located on the side of the connecting portion 221 facing the column 21, and the receiving portion 222 is used to receive the battery pack 9. The feeding end of the receiving portion 222 is installed with a wire binding block 7, which is used to bind and fix various cables of the battery cluster, fire protection pipes and liquid cooling pipes of the container, etc., and is used to organize the wire harness. The width of the feeding end of the connecting portion 221 is larger than the width of the discharging end of the connecting portion 221, which is mainly used to position the two sides of the battery pack 9, so that the installer can push the battery pack 9 into the bracket 22.

[0032] The implementation principle of a battery cluster bracket structure in the embodiment of the present application is as follows: the installer pushes the battery pack 9 from the feed end of the bracket 22, and the wider feed end of the connection part 221 positions and supports both sides of the battery pack 9, making it easier for the installer to determine the pushing direction. The battery pack 9 contacts the slide bar 4, which is a special polymer material with excellent lubricity, making it easier to push the battery pack 9, while improving the wear resistance of the bracket 22 and reducing the possibility of damage to the bracket 22.

[0033] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
