Description

Technical Field

[0001] The utility model relates to the technical field of battery clusters, in particular to a battery cluster on the DC side of energy storage. Background Art

[0002] A battery combination body formed by connecting battery monomers in series, parallel or series-parallel connection modes and independently operating after being connected with an energy storage converter and auxiliary facilities is the main equipment on the DC side of energy storage.

[0003] For example, the disclosed document with the application number 202320681065.1 discloses a battery cluster. When the battery cluster needs to dissipate heat, each heat dissipation air duct passes through a plurality of air distribution plates to blow cold air to each battery insertion box of the installation part. The air distribution plates can make the cold air passing through the air distribution plates evenly distributed, so as to reduce the temperature difference of each battery insertion box of the battery cluster, and further improve the heat dissipation effect of the battery cluster. However, for this battery cluster on the DC side of energy storage, when assembling the battery pack, the size and shape of the entire battery rack are relatively fixed and the dimensions will not change. According to different use sites, it is necessary to measure and customize a new battery rack to adapt to the site size for use. It is difficult to flexibly assemble and distribute the battery rack according to the actual occupied area of use, resulting in the need to prepare multiple specifications of battery racks, thus increasing the cost. The use range of the overall device has certain limitations and poor practicability.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structural deficiencies, and a battery cluster on the DC side of energy storage is proposed. Content of the Utility Model

[0010] Preferably, the opposite sides of the surface of the support frame are correspondingly provided with insertion slots, and the rear ends of the inner surfaces of the insertion slots are fixedly provided with thrust springs.

[0011] Preferably, an installation groove plate is slidably inserted into the insertion slot, and a battery pack is placed in the upper groove of the surface of the installation groove plate.

Specific embodiments

[0023] 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 making creative efforts belong to the scope of protection of the present utility model.

[0024] As Figures 1-3 shown, a battery cluster on the DC side of energy storage includes a top plate 1. On the left and right sides below the surface of the top plate 1, support frames 2 are fixedly installed. The top plate 1 is divided into upper and lower two parts, which together with the support frames 2 form a battery rack. And on the left side of the surface of the left support frame 2, two insertion blocks 3 are symmetrically and fixedly installed up and down, and a locking member 5 is arranged on the right side of the surface of the right support frame 2. Positioning grooves 4 are opened on the opposite sides of the surfaces of the insertion blocks 3.

[0025] By adopting the above - mentioned technical solution, by inserting the insertion blocks 3 into the locking member 5, the two battery racks can be assembled as a whole, so as to be adaptively adjusted according to the space occupation requirements.

[0026] Furthermore, the locking member 5 includes two fixed blocks 501 symmetrically and fixedly installed up and down on the right side of the surface of the right support frame 2. In the middle of the opposite sides of the outer surfaces of the fixed blocks 501, a connecting frame 502 is fixedly installed, and a slot 503 is opened at the right end of the surface of the fixed block 501.

[0027] By adopting the above technical solution, the fixing block 501 corresponds to the insertion block 3 in position, so that when the two battery racks are spliced, the insertion block 3 can be exactly aligned with the slot 503 and inserted.

[0028] Further, the locking member 5 further includes a locking pin 504 that slidably penetrates through one side of the inner surface of the fixing block 501. One end of the locking pin 504 located inside the slot 503 is provided with an inclined surface, and the end slides inside the connecting frame 502. Moving rods 505 are rotatably provided at opposite ends of the locking pin 504, and the front ends of the moving rods 505 slidably penetrate through the connecting frame 502.

[0029] By adopting the above technical solution, the insertion block 3 can use the inclined surface to push the locking pin 504 to retract and be received into the connecting frame 502; the movement of the locking pin 504 will drive the movement of the moving rod 505 to transmit the movement variable of the locking pin 504.

[0030] Further, the locking member 5 further includes the same movable plate 506 rotatably installed at the front end of the moving rod 505. Tension springs 507 are fixedly provided at the upper and lower ends of the rear side of the surface of the movable plate 506, and the rear ends of the tension springs 507 are fixedly connected to the front side of the outer surface of the connecting frame 502.

[0031] By adopting the above technical solution, when the locking pin 504 retracts, the moving rod 505 will push the movable plate 506 to extend forward, and the movable plate 506 will push the moving rod 505 to move back to its original position under the action of the tension spring 507, thereby pushing the locking pin 504 back to its original position, so that the locking pin 504 can be inserted into the positioning groove 4 to fix the insertion block 3.

[0032] As Figures 4-5 shown, insertion slots 6 are correspondingly formed on opposite sides of the surface of the support frame 2. Thrust springs 7 are fixedly provided at the rear ends of the inner surfaces of the insertion slots 6. An installation groove plate 8 is slidably inserted inside the insertion slots 6. A battery pack 9 is placed in the upper groove of the surface of the installation groove plate 8.

[0033] By adopting the above technical solution, the thrust spring 7 provides a forward driving force to the installation groove plate 8.

[0034] Further, a receiving cavity 10 is formed on one side of the front end of the inner surface of the insertion slot 6. A telescopic spring 11 is fixedly installed at the end of the inner surface of the receiving cavity 10 away from the opening. A baffle 12 is fixedly provided at the end of the telescopic spring 11 close to the opening of the receiving cavity 10.

[0035] By adopting the above technical solution, the receiving cavity 10 can cause the baffle 12 to contract and open the opening of the insertion slot 6; the elastic force of the telescopic spring 11 pushes the baffle 12 to always keep the opening of the insertion slot 6 closed under normal conditions.

[0036] Further, the front side of the surface of the baffle 12 is arranged as an inclined surface, and the baffle 12 is slidably arranged inside the converging cavity 10. A pull rod 13 is fixedly installed in the middle of the telescopic spring 11 on the surface of the baffle 12 close to the inside of the converging cavity 10. One end of the pull rod 13 slidably penetrates through the support frame 2.

[0037] By adopting the above technical solution, when the mounting groove plate 8 is inserted into the insertion slot 6, the inclined surface can be used to push the baffle 12 to contract into the converging cavity 10; the pull rod 13 pulls the baffle 12 to contract into the converging cavity 10 for the second time. At this time, the front end of the mounting groove plate 8 loses the limit of the baffle 12 and will pop out directly under the action of the thrust spring 7, so that the mounting groove plate 8 can be quickly disassembled.

[0038] Working principle: When using the battery cluster on the DC side of the energy storage, first, assemble an appropriate number of battery racks according to the site conditions. Insert the plug 3 into the slot 503, and use the inclined surface to push the locking pin 504 to move and contract into the connecting frame 502. At this time, the locking pin 504 will push the movable plate 506 to move forward through the movable rod 505, and the tension spring 507 will be stretched. When the locking pin 504 is flush with the positioning groove 4, the tension spring 507 pulls the movable plate 506 to reset, thereby pushing the movable rod 505 to insert the locking pin 504 into the positioning groove 4, so as to fix the plug 3, and thus assemble and combine two battery racks. Assemble them with each other in turn. After assembly, place the battery pack 9 on the mounting groove plate 8, and then leave enough assembly space in the battery rack according to the battery pack 9 of different thicknesses. Select a suitable insertion slot 6 to assemble the mounting groove plate 8 and the battery rack. The mounting groove plate 8 is slidably inserted into the insertion slot 6, and the inclined surface is used to push the baffle 12 to contract into the converging cavity 10. When the mounting groove plate 8 is completely inserted to the bottom, it will squeeze the thrust spring 7. At this time, the baffle 12 will extend outward under the action of the telescopic spring 11, so as to block the opening of the insertion slot 6, so that the mounting groove plate 8 can be stably assembled in different insertion slots 6. If the mounting groove plate 8 needs to be adjusted for the second time later, only need to pull the baffle 12 to contract into the converging cavity 10 for the second time through the pull rod 13. At this time, the front end of the mounting groove plate 8 loses the limit of the baffle 12 and will pop out directly under the action of the thrust spring 7, so that the mounting groove plate 8 can be quickly disassembled. When the entire battery racks need to be independently disassembled from each other, only need to pull the movable plate 506 forward, and the locking pin 504 can be pulled by the movable rod 505 to contract into the connecting frame 502 again, and the battery racks can be disassembled. This is the working principle of the battery cluster on the DC side of the energy storage.
