Description

Technical Field

[0001] This utility model relates to the field of battery energy storage module technology, specifically a foldable sodium-ion battery energy storage module. Background Technology

[0002] A battery energy storage module is a unit composed of multiple battery cells connected in series and parallel. It is designed to provide higher voltage and capacity. The battery energy storage module is an intermediate-level component in the battery system. It is assembled from multiple cells to provide the required voltage and capacity and ensure the safe and stable operation of the battery system.

[0003] According to a lithium battery energy storage module proposed in Chinese patent CN219419193U, the device allows for the adjustment of the fixing slot position by loosening the set bolts and pulling up and down the fixing plate according to the installation position of the lithium battery energy storage module. When the lithium battery energy storage module is working normally, the cooling fan starts to draw external air into the storage compartment through the dust cover. At this time, the filter cloth can easily filter impurities in the air. The filtered air enters the storage compartment to cool the lithium battery while pushing the high temperature inside the storage compartment out through the heat dissipation frame.

[0004] However, this patent still has some shortcomings. Although the device can filter impurities in the air through the filter cloth to prevent excessive impurities from affecting the heat dissipation of the module, in daily use, some battery energy storage modules are relatively large, making it inconvenient for users to carry them when they are about to engage in outdoor activities. If the larger battery energy storage modules could be folded, it would be easier for users to store and transport them during use. Therefore, we propose a foldable sodium-ion battery energy storage module. Utility Model Content

[0005] The purpose of this invention is to provide a foldable sodium-ion battery energy storage module, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a foldable sodium-ion battery energy storage module, comprising a battery energy storage module body, a frame one fixedly installed on the outer wall of the battery energy storage module body, a frame two movably installed on the side wall of the frame one via hinges, a folding assembly provided on the outer wall of the frame one, the folding assembly including a positioning post fixedly installed on the outer wall of the frame one, a hook slidably connected to the outer wall of the positioning post, the other end of the hook being movably connected to the outer wall of the frame two via a hinge. By setting the folding assembly, in order to facilitate users to carry the larger battery energy storage module body, it is necessary to fold the battery energy storage module body, thereby reducing the space of the battery energy storage module body. At this time, the operator can flip the frame two to make the bottom of the frame two fit with the top of the frame one, and then rotate the hooks on both sides of the frame one to make the inner wall of the hook engage with the outer wall of the positioning post, so as to limit the folding of the frame one and frame two, thereby achieving the purpose of folding the battery energy storage module body.

[0007] Preferably, the folding assembly further includes a rectangular block 1 fixedly installed on one side wall of the frame. A magnetic block 1 is fixedly connected to the top of the rectangular block 1, and a magnetic block 2 is magnetically connected to the top of the magnetic block 1.

A T-shaped block is slidably connected to the inner side wall of the rectangular block 2, and a U-shaped block is fixedly connected to the side wall of the T-shaped block. When the hook and the positioning post are engaged, the magnetic block 1 and the magnetic block 2 will attract each other under the action of magnetic attraction, thereby further improving the stability of the frame 1 and the frame 2 after folding. Then, the T-shaped block is inserted into the inner side wall of the rectangular block 2, and the U-shaped block is used to limit the position of the rectangular block 1 and the rectangular block 2, thereby improving the stability of the battery energy storage module body after folding.

The top side wall of the L-shaped block is fixedly connected to the outer wall of the frame one. The inner side wall of the L-shaped block is slidably connected to the outer wall of the other end of the limit post. The connection involves a heat dissipation component. During the use of the battery energy storage module, a large amount of heat is generated, necessitating heat dissipation to extend its lifespan. To address this, the operator pulls a lever, moving it along with a limiting post. The L-shaped block is then inserted into the hollow block, causing the top post of the filter frame to insert into the bottom inner wall of frame one, ensuring the top of the filter frame aligns with the bottom of frame one. Releasing the lever, the spring's reaction force resets the limiting post, inserting it into the side inner wall of the L-shaped block, thus completing the installation and fixing of the filter frame.

An output shaft is fixedly installed at the output end of the motor, and a heat dissipation fin is fixedly connected to the top outer wall of the output shaft. The heat dissipation fin is located below the battery energy storage module body. After the filter frame is installed, the operator can turn on the motor to make the output shaft rotate. After the output shaft rotates, it will rotate with the heat dissipation fin, so that the heat dissipation fin can blow air to cool the battery energy storage module body and improve the stability of the battery energy storage module body during operation.

[0010] Preferably, there are two hooks, which are symmetrically distributed along the center plane of frame two. With this setting, the two hooks can be engaged with the positioning post to achieve folding and limiting of frame one and frame two.

The top outer wall of each insertion post is adapted to the bottom inner wall of the frame. This arrangement allows for easy installation and positioning of the filter frame using the four insertion posts.

[0014] Preferably, the bottom outer wall of the L-shaped block is adapted to the inner wall of the hollow block, and there are four L-shaped blocks, which are grouped in pairs, with the two groups of L-shaped blocks symmetrically distributed along the central face of the frame.

[0015] Preferably, the inner walls of frame one and frame two are fixedly connected to the outer walls of the two battery energy storage module bodies, respectively.

[0018] (1) The foldable sodium-ion battery energy storage module is designed with a folding component. In order to facilitate users to carry the large battery energy storage module body, the battery energy storage module body needs to be folded to reduce the space of the battery energy storage module body. At this time, the operator can flip the second frame to make the bottom of the second frame fit with the top of the first frame. Then, by rotating the hooks on both sides of the first frame, the inner wall of the hooks is engaged with the outer wall of the positioning post to achieve the limitation of the first and second frames after folding, thus achieving the purpose of folding the battery energy storage module body. After the hooks are engaged with the positioning post, the magnetic block one and the magnetic block two will be attracted by the magnetic attraction, thereby further improving the stability of the first and second frames after folding. Then, the T-shaped block is inserted into the inner wall of the side of the second rectangular block, and the U-shaped block is used to limit the first and second rectangular blocks, thereby improving the stability of the battery energy storage module body after folding.

[0019] (2) The foldable sodium-ion battery energy storage module, by setting a heat dissipation component, will generate a lot of heat during the use of the battery energy storage module body. Therefore, it is necessary to dissipate heat from the battery energy storage module body to improve the service life of the battery energy storage module body. At this time, the operator can pull the pull block to make the pull block move with the limit post. Then, insert the L-shaped block into the interior of the hollow block so that the top of the filter frame inserts into the bottom inner wall of the frame one, so that the top of the filter frame fits with the bottom of the frame one. Then release the pull block. Under the reaction of the spring, the limit post will be reset and inserted into the side inner wall of the L-shaped block to complete the installation and fixation of the filter frame.

Then, the filter frame 422 is released. When the pull block 425 is released, the limiting post 424 will be reset under the reaction force of the spring 426, causing the limiting post 424 to insert into the inner side wall of the L-shaped block 427, so as to complete the installation and fixation of the filter frame 422.

The purpose of folding the main body 3 is that after the hook 412 and the positioning post 411 are engaged, the magnetic block 414 and the magnetic block 415 will be attracted together under the action of magnetism, thereby further improving the stability of the frame 1 and frame 2 after folding. Then, the T-shaped block 417 is inserted into the inner side wall of the rectangular block 416, and the U-shaped block 418 is used to limit the rectangular block 413 and the rectangular block 416, improving the stability of the battery energy storage module main body 3 after folding.
