Description

Technical Field

[0001] The utility model relates to the technical field of battery pack modularization, and particularly relates to a modular connection structure for an energy storage battery pack. Background Technique

[0002] Battery pack modularization is to assemble multiple battery modules together to form a complete battery pack, thereby improving the energy density and reliability of the battery system. And due to the modular connection of the battery pack, the maintenance and replacement of the battery are more convenient.

[0003] However, when the existing modular connection structure of the energy storage battery pack connects the battery modules, it usually adopts the methods of welding or screwing. When disassembling the battery modules, it is necessary to first remove the connected wires, resulting in troublesome and time-consuming disassembly and assembly of the battery modules in the battery pack. In addition, since some wires remain connected when each battery pack is not completely disassembled, there is still a short-circuit current in the battery pack, and it is more likely to have a leakage short-circuit situation, resulting in potential safety hazards when disassembling the battery pack. Content of the Utility Model

[0004] The purpose of the utility model is to provide a modular connection structure for an energy storage battery pack to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A modular connection structure for an energy storage battery pack, including a housing. One side of the top of the housing is hinged with a flip cover. The bottom end of the flip cover is electrically connected to a first conductive sheet. The inside of the housing is provided with a first partition and a second partition. First latches are installed at the top of both side walls and the front of the housing. Second latches are installed at the bottom of both side walls and the front of the housing. The bottom of the housing is provided with a bottom plate. A groove is opened at the top end of the bottom plate. A partition strip is embedded in the inner wall of the groove. The bottom of the inner side of the groove is electrically connected to a second conductive sheet. The top of the second conductive sheet is electrically connected to a battery pack.

[0006] Preferably, a handle is movably connected to the middle of the top end of the flip cover, and an external interface is opened on one side of the top end of the flip cover.

[0007] Preferably, the external interface is electrically connected to the first conductive sheet, and the battery pack is electrically connected to the first conductive sheet.

[0008] Preferably, a plurality of card slots are opened on the inner wall of the housing. The first partition and the second partition are respectively movably connected to the card slots. The first partition and the second partition are movably connected to the housing through the card slots.

[0011] Preferably, the bottom plate is movably engaged and connected with the housing through a second lock, and the flip cover is movably connected with the housing through a first lock.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. For this modular connection structure of the energy storage battery pack, through the first lock, the second lock, the flip cover, the housing and the bottom plate, when the connection structure needs to be disassembled from the battery pack, the first lock and the second lock can be directly opened, so that the flip cover can be opened from the top of the housing, and at the same time, the bottom plate can be smoothly separated from the bottom of the housing, realizing the rapid disassembly of the connection structure, simplifying the disassembly process of the structure and the battery pack, and thus saving the time required for disassembling the battery module and the structure.

[0023] As Figures 1 to 4 shown, the modular connection structure of the energy storage battery pack in this embodiment includes a sleeve case 5. One side of the top of the sleeve case 5 is hinged with a flip cover 1. The bottom end of the flip cover 1 is electrically connected to a first conductive sheet 12. The inside of the sleeve case 5 is provided with a first partition 10 and a second partition 11. First lock catches 4 are installed at the top of both side walls and the front of the sleeve case 5. Second lock catches 8 are installed at the bottom of both side walls and the front of the sleeve case 5. The bottom of the sleeve case 5 is provided with a bottom plate 7. A groove 18 is formed at the top end of the bottom plate 7. A partition strip 17 is embedded in the inner wall of the groove 18. The bottom of the inner side of the groove 18 is electrically connected to a second conductive sheet 16. The top of the second conductive sheet 16 is electrically connected to a battery pack 9.

[0024] Specifically, openings are provided at both the top and bottom of the casing 5, enabling the casing 5 to be directly lifted upward after the flip cover 1 is opened and separated from the bottom plate 7, achieving rapid separation from the internal battery pack 9, thus facilitating the disassembly of the casing 5 and the battery pack 9. The function of the flip cover 1 is to seal the top of the casing 5, ensuring that the battery pack 9 placed inside the casing 5 is in a closed state. The function of the first conductive sheet 12 is to connect the positive electrodes of the battery packs 9 in series, forming a modular positive electrode for the battery packs 9. The functions of the first partition 10 and the second partition 11 are to separate the individual battery packs 9, preventing interference between them and thus enhancing the stability of each individual battery pack 9. The number of the first latches 4 is three, enabling the flip cover 1 to maintain a connection relationship with the other three faces of the casing 5, which is conducive to temporarily locking and fixing the flip cover 1 and the casing 5, protecting the battery pack 9 inside the casing 5. The number of the second latches 8 is four, located on the four side walls of the bottom plate 7 respectively. During use, they can be temporarily locked with the casing 5, keeping the bottom of the bottom plate 7 connected to the casing 5. The function of the bottom plate 7 is to support the bottom of the battery pack 9, enabling the battery packs 9 to be smoothly assembled into a module inside the casing 5. The groove 18 allows the bottom of the battery pack 9 to be stably placed on the bottom plate 7, facilitating the subsequent connection of the battery pack 9 with the casing 5. The partition strip 17 can limit the individual battery packs 9, making it more conducive for the battery packs 9 to maintain a connection with the second conductive sheet 16 on the bottom plate 7. The function of the second conductive sheet 16 is to connect the negative electrodes of the battery packs 9 in series, forming a modular negative electrode for the battery packs 9.

[0025] Furthermore, a handle 3 is movably connected to the middle of the top end of the flip cover 1, and an external interface 2 is provided on one side of the top end of the flip cover 1. The handle 3 facilitates the user to move and carry the connection structure and the battery module, making the use of the connection structure more convenient.

[0026] Furthermore, the external interface 2 is electrically connected to the first conductive sheet 12, and the battery pack 9 is electrically connected to the first conductive sheet 12. The external interface 2 integrates the positive electrode of the first conductive sheet 12 and the negative electrode of the second conductive sheet 16, enabling the connection structure to directly form a larger modular battery for use, thereby enhancing the practicality of this connection structure.

[0027] Furthermore, a plurality of card slots 15 are provided on the inner wall of the casing 5. The first partition 10 and the second partition 11 are respectively movably connected to the card slots 15. The first partition 10 and the second partition 11 are movably connected to the casing 5 through the card slots 15. The bottom ends of the card slots 15 are in a closed state, enabling the casing 5 to lift the first partition 10 and the second partition 11 simultaneously when lifted, facilitating the separation of the first partition 10 and the second partition 11 from the battery pack 9.

[0028] Furthermore, a socket 14 is provided at the top end of the first partition plate 10, and a bayonet 13 is provided at the bottom end of the second partition plate 11. The first partition plate 10 and the second partition plate 11 are movably engaged and connected through the bayonet 13 and the socket 14. The socket 14 and the bayonet 13 are engaged with each other, so that the first partition plate 10 and the second partition plate 11 form a grid structure, thereby realizing the separation of a single battery pack 9 and being beneficial to protecting the single battery pack 9.

[0029] Furthermore, a collar 6 is sleeved in the middle of the outer wall of the casing 5. The collar 6 is made of an insulating material and protrudes from the outer wall of the casing 5, so that it is easier to exert force when lifting the casing 5. At the same time, the outer wall of the casing 5 can be insulated, improving the safety when lifting the casing 5.

[0030] Furthermore, the bottom plate 7 is movably engaged and connected with the casing 5 through the second lock 8, and the flip cover 1 is movably connected with the casing 5 through the first lock 4. After the first lock 4 and the second lock 8 are all locked, the flip cover 1, the casing 5 and the bottom plate 7 form a complete and enclosed structure, enabling the internal battery packs 9 to be modularly combined.

[0031] The usage method of this embodiment is as follows: When using this modular connection structure of the energy storage battery, the battery packs 9 to be modularized can be sequentially placed in the grooves 18 corresponding to the partition strips 17 on the bottom plate 7 first, so that the bottom of the battery pack 9 is in contact and fit with the second conductive sheet 16 at the bottom of the groove 18. Then, the casing 5 is sleeved on the top of the bottom plate 7, and then the second lock 8 is locked to fix the bottom plate 7 and the casing 5. Then, the first partition plate 10 and the second partition plate 11 are fitted and docked through the bayonet 13 and the socket 14, so that the first partition plate 10 and the second partition plate 11 form a grid structure, and then they are pushed into the casing 5 along the sliding grooves on the inner wall of the casing 5, so that the first partition plate 10 and the second partition plate 11 separate the single battery packs 9 in the casing 5. Then, the flip cover 1 can be flipped so that the flip cover 1 covers the top of the casing 5, and then the first lock 4 is locked to temporarily lock and fix the flip cover 1 and the top of the casing 5. At the same time, the first conductive sheet 12 on the flip cover 1 will be in contact and fit with the top end of the battery pack 9, making the positive electrodes of the battery packs 9 in series. At this time, the connection structure realizes the modular combination of the battery packs 9. When it is necessary to disassemble the connection structure, only the above steps need to be operated in reverse.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
