Description

Technical Field

[0001] This utility model relates to the technical field of energy storage batteries, specifically an energy storage battery rack and energy storage device. Background Technology

[0002] Battery racks in energy storage devices require powder coating for corrosion protection. After powder coating, the surface has a high coefficient of friction. When installing lithium-ion batteries onto the rack, the weight of the batteries themselves increases the friction between the batteries and the rack, making it more difficult to push in or remove the battery pack. This increases the difficulty of installing and maintaining the entire system, reducing efficiency. Furthermore, friction between the lithium-ion batteries and the paint on the rack during installation or removal can damage the paint, rendering the rack ineffective against corrosion. Utility Model Content

[0003] In order to overcome the defects in the prior art, the present invention provides an energy storage battery rack and an energy storage device. The energy storage battery rack has a protective layer on the crossbeam to reduce the coefficient of friction, thereby reducing the friction between the battery pack and the energy storage battery rack and thus avoiding wear on the paint surface of the energy storage battery rack during installation.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: an energy storage battery rack, comprising:

[0005] Connectors;

[0006] A crossbeam is fixedly connected to the connector and is spaced apart along the length of the connector. The crossbeam has a mounting portion for mounting the battery, and at least the portion of the crossbeam in contact with the battery has a protective layer for reducing the coefficient of friction.

[0007] Through the above technical solution, the energy storage battery rack disclosed in this application has a protective layer on the crossbeam to reduce the coefficient of friction, thereby reducing the friction between the battery pack and the energy storage battery rack and thus avoiding wear on the paint surface of the energy storage battery rack during installation.

[0008] Furthermore, it also includes a support member for strengthening the support force of the crossbeam, the support member being connected and fixed to the connector and in contact with the mounting part.

[0009] The support member strengthens the crossbeam's support, thereby preventing the crossbeam from bending due to the weight of the battery.

[0010] Furthermore, the crossbeam includes:

[0011] A first connecting plate is fixedly connected to the connecting member.

[0012] The mounting plate is fixedly connected to the first connecting plate, and the width direction of the mounting plate is perpendicular to the length direction of the connecting member.

[0013] With the above technical solution, the mounting plate is parallel to the horizontal plane, thereby ensuring the stability of the battery pack after it is installed on the energy storage battery rack.

[0014] Furthermore, one end of the support member along its length direction has an extension that extends beyond the length of the mounting plate, and the extension is bent at a predetermined angle toward the mounting plate to form a first limiting portion for restricting the movement of the battery.

[0015] By setting the first limiting part, excessive horizontal displacement of the battery can be avoided during transportation.

[0016] Furthermore, the end of the extension is bent inward at a predetermined angle to form a second limiting portion for restricting the movement of the battery.

[0017] The second limiting part can prevent excessive vertical displacement of the battery during transportation.

[0018] Furthermore, the support member includes:

[0019] The second connecting plate is connected and fixed to the connecting member;

[0020] A support plate is connected to the second connecting plate and is attached to the mounting plate in parallel. The support plate has an extension at one end along its length.

[0021] Through the above technical solution, the support member is connected and fixed to the connector via the second connecting plate, and the support plate connected to the second connecting plate strengthens the supporting force of the mounting plate, and the extension is formed by bending the support plate. That is, the support member can be integrally formed from a single plate through cutting and bending.

[0022] Furthermore, the connector includes at least two parallel columns, which are spaced apart along the length of the beam.

[0023] Multiple columns are used to fix the crossbeams and supports, making the entire energy storage battery rack structure simple.

[0024] Furthermore, the crossbeam is provided with a first through hole, and the column is provided with a first threaded hole. The crossbeam and the column can be connected and fixed by bolts passing through the first through hole and the second threaded hole.

[0025] The support member is provided with a second through hole, and the column is provided with a second threaded hole. The support member and the column can be connected and fixed by bolts passing through the second through hole and the second threaded hole.

[0026] With the above technical solution, any damaged beam or support can be replaced individually, thereby reducing the cost of replacing the energy storage battery rack.

[0027] Furthermore, the crossbeam is made of magnesium-aluminum plate.

[0028] The support component is made of Q235 steel.

[0029] Compared to battery racks produced by traditional powder coating processes, the crossbeams made of magnesium-aluminum plate in this application have good corrosion resistance and a low coefficient of friction, which can significantly improve assembly efficiency.

[0030] The support components made of Q235 steel are sufficient to provide support for the battery, while being inexpensive.

[0031] An energy storage device includes a battery pack mounted on the aforementioned energy storage battery rack.

[0032] Based on the above technical solution, the beneficial effects of this utility model are as follows:

[0033] 1. The energy storage battery rack disclosed in this application has a protective layer on the crossbeam to reduce the coefficient of friction, thereby reducing the friction between the battery pack and the energy storage battery rack and thus preventing the paint surface of the energy storage battery rack from being worn during installation.

[0034] 2. This application strengthens the support of the crossbeam by setting up support components, thereby preventing the crossbeam from being bent by the battery.

[0044] Example: Example 1 discloses an energy storage battery rack, comprising:

[0045] Connectors;

[0046] A crossbeam 1 is connected and fixed to the connector and is spaced apart along the length of the connector. The crossbeam 1 is provided with a mounting part for installing a battery, and at least the part of the crossbeam 1 that contacts the battery is provided with a protective layer to reduce the coefficient of friction.

[0047] The protective layer can be a magnesium-aluminum plate, an aluminum-zinc-magnesium steel plate, or any other material with a low coefficient of friction.

[0048] Through the above technical solution, the energy storage battery rack disclosed in this application has a protective layer on the crossbeam 1 to reduce the coefficient of friction, so as to reduce the friction between the battery pack and the energy storage battery rack, thereby avoiding wear on the paint surface of the energy storage battery rack during installation.

[0049] In some feasible embodiments, the connector includes at least two parallel columns 3, which are spaced apart along the length of the beam 1.

[0050] The connector can also be replaced by a single plate or other mounting component that can fix the crossbeam 1.

[0051] In this embodiment, as Figure 1 As shown, the connector includes two parallel columns 3, which are respectively located at both ends of the crossbeam 1. That is, the energy storage battery rack is formed by multiple crossbeams 1 fixed at intervals to two columns 3, resulting in a simple overall structure.

[0052] The detachable connection between the crossbeam 1 and the column 3 can be achieved in some feasible embodiments, such as... Figure 2 As shown, the crossbeam includes:

[0053] The first connecting plate 11 is connected and fixed to the column 3, and the upward-facing side of the first mounting plate 11 serves as the mounting part for installing the battery.

[0054] Mounting plate 12 is connected and fixed to the first connecting plate 11, and the width direction of the mounting plate 12 is perpendicular to the length direction of the column 3.

[0055] With the above technical solution, the mounting plate 12 is parallel to the horizontal plane, thereby ensuring the stability of the battery pack after it is installed on the energy storage battery rack.

[0056] The first connecting plate 11 has first through holes 111 at both ends along its length, and the column 3 has a first threaded hole that matches the first through hole. By passing bolts through the first through hole 111 and the second threaded hole, the crossbeam 1 and the column 3 can be connected and fixed. This design allows for a detachable connection between the crossbeam 1 and the column 3. If any crossbeam 1 is damaged, it can be replaced individually, thereby reducing the cost of replacing the energy storage battery rack.

[0057] In some feasible embodiments, the first connecting plate 11 and the mounting plate 12 are integrally formed.

[0058] The energy storage battery rack also includes a support member 2 for reinforcing the support force of the crossbeam 1. The support member 2 is connected and fixed to the column 3 and contacts the mounting part. By strengthening the support force of the crossbeam 1 through the support member 2, the crossbeam 1 is prevented from bending due to the weight of the battery.

[0059] The support member 2 has an extension at one end extending beyond the length of the mounting plate 12. The extension is bent at a predetermined angle toward the mounting plate 12 to form a first limiting part 23 for restricting battery movement. The first limiting part 23 prevents excessive horizontal displacement of the battery during transportation.

[0060] The end of the extension is bent inward at a predetermined angle to form a second limiting portion 24 for restricting battery movement. When installing the battery pack, at least a portion of the second limiting portion 24 is located above the tail of the battery pack near the second limiting portion 24. The provision of the second limiting portion 24 can prevent excessive vertical displacement of the battery during transportation.

[0061] The detachable connection between the support member 2 and the column 3 is described in some feasible embodiments, such as... Figure 3 As shown, the support member includes:

[0062] The second connecting plate 21 is connected and fixed to the column 3;

[0063] The support plate 22 is connected to the second connecting plate 21 and is attached to the mounting plate 12 in parallel. The support plate 22 has an extension at one end along its length direction.

[0064] Combination Figure 2 As shown, the extension is bent toward the mounting plate 12 so that it is perpendicular to the mounting plate 12, forming the first limiting portion 23. The end of the extension is bent inward at a predetermined angle to form the second limiting portion 24.

[0065] When installing the battery pack, at least a portion of the second limiting portion 24 is located above the tail of the battery pack near the second limiting portion 24. If the battery shifts upwards during transportation, the tail of the battery pack may strike the second limiting portion 24. In the structure of this application, combined with... Figure 2 , 3 As shown, the second limiting part 24 is connected to the support plate 22, and the support plate 22 is disposed below the mounting plate 12, that is, the support plate 22 and the mounting plate 12 simultaneously provide support for the second limiting part 24.

[0066] Through the above technical solution, the support member 2 is connected and fixed to the column 3 via the second connecting plate 21, and the support plate 22 connected to the second connecting plate 21 strengthens the supporting force of the mounting plate 12, and the extension is formed by bending the support plate 22. That is, the support member 2 can be integrally formed from a single plate through cutting and bending.

[0067] Among them, such as Figure 3 As shown, the second connecting plate 21 has a second through hole 211, and the column 3 has a second threaded hole that mates with the second through hole 211. By passing bolts through the second through hole 211 and the second threaded hole, the support member 2 and the column 3 can be detachably connected. If any of the support members 2 is damaged, it can be replaced individually, thereby reducing the cost of replacing the energy storage battery rack.

[0068] The crossbeam 1 and the support 2 are respectively connected to the column 3 by bolts, so that the crossbeam 1 can better bear the static load, impact and vibration in the vertical direction.

[0069] In some feasible embodiments, combined with Figure 2 , 3 As shown, the first connecting plate 11 has three first through holes 111 at each end, and correspondingly, the column 3 has three first threaded holes that mate with the first through holes 111. The second connecting plate 21 has three second through holes 211 at each end, and correspondingly, the column 3 has three second threaded holes that mate with the second through holes 211. It should be noted that the number of first through holes 111 and second through holes 211 can be set according to requirements. The smaller the battery weight, the fewer the number of first through holes 111 and second through holes 211; the larger the battery weight, the more the number of first through holes 111 and second through holes 211.

[0070] In some feasible embodiments, the support member 2 is made of Q235 steel. The support member 2 made of Q235 steel is sufficient to provide support for the battery, while being inexpensive.

[0074] Compared to battery racks produced using traditional powder coating processes, the crossbeam 1 made of magnesium-aluminum plate in this application has excellent corrosion resistance and a low coefficient of friction, which can significantly improve assembly efficiency. Furthermore, the magnesium-aluminum plate material has self-healing capabilities; magnesium elements migrate to worn areas to form a dense protective film (such as magnesium hydroxide / magnesium carbonate), inhibiting corrosion and reducing the increase in surface roughness caused by rust.

[0075] The crossbeam 1 can also be made of aluminum-zinc-magnesium steel plate or any other material with a low coefficient of friction.

[0076] In some feasible embodiments, the connector includes at least two parallel columns 3, which are spaced apart along the length of the beam 1.

[0077] The connector can also be replaced by a single plate or other mounting component that can fix the crossbeam 1.

[0078] In this embodiment, as Figure 1 As shown, the connector includes two parallel columns 3, which are respectively located at both ends of the crossbeam 1.

[0082] With the above technical solution, the mounting plate 12 is parallel to the horizontal plane, thereby ensuring the stability of the battery pack after it is installed on the energy storage battery rack.

[0083] The first connecting plate 11 has first through holes 111 at both ends along its length, and the column 3 has a first threaded hole that matches the first through hole. By passing bolts through the first through hole 111 and the second threaded hole, the crossbeam 1 and the column 3 can be connected and fixed. This design allows for a detachable connection between the crossbeam 1 and the column 3. If any crossbeam 1 is damaged, it can be replaced individually, thereby reducing the cost of replacing the energy storage battery rack.

[0084] In some feasible embodiments, the first connecting plate 11 and the mounting plate 12 are integrally formed.

[0085] The energy storage battery rack also includes a support member 2 for reinforcing the support force of the crossbeam 1. The support member 2 is connected and fixed to the column 3 and contacts the mounting part. By strengthening the support force of the crossbeam 1 through the support member 2, the crossbeam 1 is prevented from bending due to the weight of the battery.

[0086] The support member 2 has an extension at one end extending beyond the length of the mounting plate 12. The extension is bent at a predetermined angle toward the mounting plate 12 to form a first limiting part 23 for restricting battery movement. The first limiting part 23 prevents excessive horizontal displacement of the battery during transportation.

[0087] The end of the extension is bent inward at a predetermined angle to form a second limiting part 24 for restricting battery movement. The second limiting part 24 prevents excessive vertical displacement of the battery during transportation.

[0090] The support plate 22 is connected to the second connecting plate 21 and is attached to the mounting plate 12 in parallel. The support plate 22 has an extension at one end along its length direction.

[0091] Combination Figure 2 As shown, the extension is bent toward the mounting plate 12 so that it is perpendicular to the mounting plate 12, forming the first limiting portion 23. The end of the extension is bent inward at a predetermined angle to form the second limiting portion 24.

[0092] Through the above technical solution, the support member 2 is connected and fixed to the column 3 via the second connecting plate 21, and the support plate 22 connected to the second connecting plate 21 strengthens the supporting force of the mounting plate 12, and the extension is formed by bending the support plate 22. That is, the support member 2 can be integrally formed from a single plate through cutting and bending.

[0093] Among them, such as Figure 3 As shown, the second connecting plate 21 has a second through hole 211, and the column 3 has a second threaded hole that mates with the second through hole 211.
