Description

Technical Field

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

[0002] In current battery energy storage systems or electric vehicle battery management systems, battery plug-ins are key components. Inserting and effectively securing them within the battery cluster cabinet is crucial. However, a series of issues with existing technologies limit the overall performance and safety of the system, particularly regarding the alignment and securement of the battery plug-in within the cabinet and transport stability.

[0003] First, existing battery boxes generally lack a limiting guide structure when inserted into the cabinet. This lack makes it difficult to precisely align the battery box with the cabinet's positioning hole during insertion. The positioning hole is usually located at the cabinet opening, which increases the difficulty of securing the battery box with screws. Due to the inaccuracy of manual alignment, multiple adjustments and even reinsertion are often required to ensure that the screws pass correctly through the preset holes. This not only reduces installation efficiency but also increases the risk of operational errors, potentially causing damage to the battery box or the cabinet.

[0004] Secondly, there are also issues with the cabinet frame design. Currently, most cabinets utilize a simple frame structure. While this structure reduces weight and manufacturing costs to a certain extent, it lacks sufficient support and stability. Especially after the battery drawer is removed and screwed in, due to the inherent limitations of the frame structure, the battery box may still wobble inside the cabinet. This wobble not only affects the overall stability of the battery system but can also be exacerbated during cabinet transportation, causing mechanical stress on the battery box and connecting components, which can lead to safety hazards such as breakage, deformation, or short circuits. Utility Model Content

[0005] To overcome at least one of the above-mentioned drawbacks of the prior art, the present invention provides a battery cluster. This solution ensures the stability of the battery plug-in box when inserted into the cabinet. A guide structure limits and secures the battery plug-in box, improving alignment accuracy and preventing the battery plug-in box from shaking during transportation, thereby increasing safety and service life.

[0006] The technical solution adopted by the present invention to solve the problem is:

[0007] A battery cluster comprises: a battery plug box, one end of the battery plug box is an insertion end, and the insertion end is provided with a first limiting structure; a battery cabinet, the battery cabinet having an insertion port, and at least one slot for inserting the battery plug box is provided from the insertion port into the battery cabinet, the slot comprising two opposite side walls, the side walls being provided with a slot track and a guide rib, the battery plug box is inserted from the insertion port and slides along the slot track, the guide rib is provided with a chamfer at one end close to the insertion port, and a second limiting structure corresponding to the first limiting structure is provided at one end of the slot away from the insertion port; when the battery plug box is inserted from the insertion port until it completely enters the slot, the guide rib abuts against two sides of the battery plug box, and the first limiting structure and the second limiting structure are fixed in position.

[0008] By adopting the above solution, the slot track and guide ribs provided within the slot provide a sliding path and guidance for the battery box, ensuring smooth insertion. The chamfered design of the guide rib near the insertion port facilitates smooth insertion of the battery box into the slot, reducing friction and collisions. Once the battery box is fully inserted into the slot, the guide ribs contact the sides of the battery box, increasing its stability within the slot and reducing wobbling. This also improves the success rate of alignment between the first and second limiting structures. Once successfully positioned and fixed, the battery box remains stable even during transportation, reducing the risk of mechanical stress on the battery box and connecting components, thereby enhancing transportation safety. This dual guidance and fixation improves the overall stability of the battery box after insertion, simplifies the fixing process, and enhances the overall performance and safety of the battery cluster.

[0009] Furthermore, one of the first limiting structure and the second limiting structure is a positioning hole, and the other is a positioning pin.

[0010] By adopting this solution, the precise tolerances between the positioning holes and the positioning pins ensure highly accurate positioning of the battery compartment when inserted into the battery cabinet. This positioning method helps reduce installation issues caused by inaccurate alignment, improves installation efficiency, and eliminates errors caused by manual operation, ensuring consistent installation accuracy every time. Once the positioning pins are inserted into the positioning holes, they effectively limit the freedom of movement of the battery compartment within the slot, preventing it from shaking vertically or horizontally. They also prevent the compartment from accidentally falling out when subjected to external forces, thereby improving the safety and reliability of the entire battery cluster.

[0011] Furthermore, the end of the positioning pin is provided with a chamfer.

[0012] By adopting the above solution, the chamfered end of the locating pin can reduce the contact area with the entrance of the locating hole, thereby reducing the friction during insertion, making it easier and smoother for the locating pin to enter the locating hole, playing a guiding role, guiding the locating pin to enter the locating hole in the correct direction, and helping to achieve more precise positioning; during the insertion process, the chamfered design can prevent the sharp edge of the locating pin from scratching the inner wall of the locating hole, protecting the locating hole from damage, improving the installation accuracy and reliability, and extending its service life.

[0013] Furthermore, the axial direction of the positioning hole and the axial direction of the positioning pin are parallel to the slot track.

[0014] By adopting the above solution, since the axial directions of the positioning holes and the positioning pins are parallel to the slot track, the positioning pins can smoothly enter the positioning holes when the battery plug-in box slides along the slot track without encountering unnecessary resistance or jamming, thereby ensuring a smooth insertion process. The battery plug-in box's freedom of movement within the slot is more effectively restricted, reducing its vertical or horizontal shaking. The parallel arrangement can more evenly transfer and distribute the load, thereby improving the overall load-bearing capacity and impact resistance of the battery cluster.

[0015] Furthermore, the end of the battery plug box opposite to the insertion end is a pull-out end, the pull-out end is provided with a first fixing structure, the slot track is provided with a second fixing structure corresponding to the first fixing structure, and the first fixing structure and the second fixing structure are fixedly connected.

[0016] By adopting the above solution, the cooperation between the first fixing structure and the second fixing structure can fix the pull-out end to the insertion port, preventing the battery plug-in box from sliding out of the insertion port, and effectively preventing the battery plug-in box from shaking or falling off during transportation, installation or use, thereby enhancing the overall stability.

[0017] Furthermore, one of the first fixing structure and the second fixing structure is a fixing screw hole, and the other end is a fixing stud, and a fixing screw is assembled between the fixing screw hole and the fixing stud.

[0018] By adopting this solution, the fixing screws secure the fixing screw holes and studs, creating a high-strength connection. This connection can withstand significant tensile and shear forces, ensuring the stability of the battery compartment within the battery cabinet. The screw locking action effectively prevents loosening of the battery compartment due to vibration, impact, and other factors during use, thereby improving the reliability of the connection. This also simplifies the installation and removal of the battery compartment, reduces maintenance difficulty and costs, and improves the maintainability of the equipment. The combination of the fixing screw holes, studs, and screws is relatively simple, resulting in low manufacturing costs and contributing to improved product competitiveness.

[0019] Furthermore, the axial direction of the fixing screw hole, the axial direction of the fixing stud, and the axial direction of the fixing screw are perpendicular to the slot track.

[0020] By adopting the above solution, the battery compartment can remain stable when subjected to lateral force, and is not easily deflected or shaken, thereby reducing loosening and damage caused by vibration; the vertical axis direction allows installers to clearly identify the correct installation direction when installing the fixing screws, thereby avoiding installation problems caused by incorrect direction; when the battery compartment needs to be maintained or replaced, the vertically arranged fixing screw holes and fixing screws make the disassembly process simpler and more direct.

[0021] Furthermore, the distance between the guide ribs corresponding to the two side walls in the slot is set to L1, the distance between the two sides parallel to the insertion port and the side wall is set to L2, and the length of the insertion end or the pull-out end of the battery plug box is set to L3, then L2>L1=L3.

[0022] With this solution, since L1 is equal to L3, when the battery box is inserted into the slot, its sides slide smoothly along the guide ribs within the slot until fully seated, avoiding installation difficulties or damage caused by misalignment. The design with L2 greater than L1 provides ample space for insertion and prevents jamming caused by overly tight dimensions. This simplifies the installation process and improves efficiency. When the battery box is fully inserted into the slot, its sides tightly mate with the guide ribs within the slot, forming a stable connection. This design helps reduce wobble and displacement within the slot, improving connection reliability.

[0023] Furthermore, a baffle is connected to one end of the slot track away from the insertion port, and the baffle abuts against the insertion end of the battery plug-in box.

[0024] By adopting this solution, the baffle acts as the end limit of the slot track, ensuring that the battery compartment can only reach the predetermined depth during insertion. This design avoids damage or connection problems caused by inserting the battery compartment too deep. Furthermore, a second limiting structure can be added to the baffle to prevent collision with the back panel of the battery cabinet.

[0025] Furthermore, in the slot, each battery plug-in box corresponds to at least two slot rails; and both sides of the insertion end and both sides of the pull-out end of each battery plug-in box abut against at least two guide ribs.

[0026] By adopting this solution, the battery compartment is more firmly supported within the slot thanks to the support of at least two slot rails and at least two guide ribs. This multi-point support structure significantly improves the stability of the battery compartment within the slot, preventing it from shaking or shifting when subjected to external forces. The design of multiple slot rails and guide ribs ensures that the battery compartment is evenly loaded during insertion, avoiding damage caused by excessive force at a single point. Furthermore, once the battery compartment is fully inserted, its weight is better distributed, reducing the burden on a single support point.

[0027] In summary, the battery cluster provided by the present invention has the following technical effects:

[0028] 1. Improved installation accuracy and efficiency: The slot track and guide ribs within the slot provide a clear insertion path and guidance for the battery box, ensuring smooth and accurate insertion into the cabinet slot. This significantly reduces the need for multiple adjustments and reinsertion due to inaccurate manual alignment, improving installation efficiency. Furthermore, the guide ribs ensure smooth insertion, reducing the risk of damage from friction and collision, further increasing the success rate of installation.

[0029] 2. Enhanced Stability: When the battery compartment is fully inserted into the slot, the guide ribs tightly contact the sides of the compartment, effectively limiting any movement within the slot. This secure connection improves the stability of the compartment within the slot, ensuring it remains securely positioned even under vibration or impact. The combined use of the first and second retaining structures further enhances the securement of the compartment within the slot, preventing it from shifting or falling out during transport or use. The guide ribs provide dual guidance and positioning.

[0030] 3. Improved Safety: The stable battery plug-in box connection structure reduces mechanical stress on the battery plug-in box and connecting components, reducing the probability of safety hazards such as cable breakage, poor contact, or short circuits. The dual-guiding and fixed design ensures the stability of the battery plug-in box during transportation, preventing damage or failure caused by shaking, and improving the transportation safety of the battery cluster.

[0031] 4. Extended service life: By reducing the risk of damage from improper installation or shaking, the overall service life of the battery box and battery cluster is extended. The stable connection structure reduces wear and fatigue caused by vibration or impact, further improving the durability of the battery cluster.

[0032] 5. Simplified maintenance: When the battery compartment needs maintenance or replacement, the stable connection structure and clear disassembly path make the operation easier and faster. This reduces the risk of damage or failure caused by improper disassembly, and reduces maintenance costs and time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0039] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described and discussed below in conjunction with the drawings of the present invention. Obviously, what is described here is only a part of the examples of the present invention, not all the examples. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0040] In order to facilitate the understanding of the embodiments of the present invention, the following will be further explained with reference to specific embodiments as examples in conjunction with the drawings, and each embodiment does not constitute a limitation on the embodiments of the present invention.

[0041] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0043] Example 1 of the present utility model is shown in FIG. Figure 1-Figure 5 As shown, a battery cluster is disclosed, including a battery plug box 1 and a battery cabinet 2, wherein the battery cabinet 2 has an insertion port 21, and at least one slot 22 for inserting the battery plug box 1 is provided from the insertion port 21 into the battery cabinet 2, that is, the ratio of the number of the insertion ports 21 to the number of the slots 22 is 1:n, n ≥ 1; the battery cabinet 2 is surrounded by a top wall 24, a bottom wall 25, a back plate 26 and two side walls 23, so each of the slots 22 has two side walls 23, and the side walls 23 are provided with a slot rail 231 and a guide rib 232 for each slot 22, the slot rail 231 is used to abut against the bottom of the battery plug box 1 to play a supporting role, and the guide rib 232 is used to limit the two sides of the battery plug box 1. Specifically, one end of the battery plug box 1 is an insertion end 11, and the other end is an insertion end 11. One end is the pull-out end 12, and the insertion end 11 is provided with a first limiting structure 111. The battery plug box 1 is inserted into the slot 22 from the insertion port 21 and slides along the slot track 231. The guide rib 232 is provided with a chamfer at one end close to the insertion port 21, and a second limiting structure 221 corresponding to the first limiting structure 111 is provided at the end of the slot 22 away from the insertion port 21. It should be noted that the correspondence here means that the first limiting structure 111 can be adapted to the second limiting structure 221 to achieve a limiting effect along the insertion direction; when the battery plug box 1 is inserted from the insertion port 21 until it completely enters the slot 22, the guide rib 232 is against both sides of the battery plug box 1, and the first limiting structure 111 and the second limiting structure 221 are fixed in position.

[0044] The chamfer of the guide rib 232 can be either an inclined surface or an arcuate surface. The closer the guide rib 232 is to the insertion opening 21, the smaller its thickness is, thereby reserving a mounting position for the insertion end 11 of the battery compartment 1. The guide rib 232 guides the battery compartment 1 smoothly into the slot 22, improving insertion convenience and ensuring stability during insertion. The chamfered design of the guide rib 232 near the insertion opening 21 facilitates smooth insertion of the battery compartment 1 into the slot 22, reducing friction and collision. When the battery compartment 1 is fully inserted into the slot 22, the guide rib 232 abuts against both sides of the battery compartment 1, increasing its stability within the slot 22 and reducing shaking. This also increases the success rate of alignment between the first limiting structure 111 and the second limiting structure 221. Once the two are successfully positioned and fixed, they remain stable even during transportation, reducing the risk of mechanical stress on the battery compartment 1 and connecting components, thereby improving transportation safety. Through the double guidance and fixation, the overall stability of the battery plug-in box 1 after insertion is improved, the fixation process is simplified, and the overall performance and safety of the battery cluster are improved.

[0045] In some embodiments, one of the first limiting structure 111 and the second limiting structure 221 is a positioning hole 1111, and the other is a positioning pin 2211. Precise tolerances are achieved between the positioning hole 1111 and the positioning pin 2211, ensuring highly accurate positioning of the battery compartment 1 when inserted into the battery cabinet 2. This positioning method helps reduce installation issues caused by inaccurate alignment, improves installation efficiency, and eliminates errors caused by manual operation, ensuring consistent installation accuracy. Once inserted into the positioning hole 1111, the positioning pin 2211 effectively limits the freedom of movement of the battery compartment 1 within the slot 22, preventing vertical or horizontal movement. It also prevents the battery compartment 1 from accidentally falling off when subjected to external forces, thereby improving the safety and reliability of the entire battery cluster. In this embodiment 1, the battery plug box 1 includes a pull-out end plate 13, an insertion end plate 14, a bottom plate 15 and two side plates 16. In order to reserve a position for the first limiting structure 111 on the insertion end plate 14, the installation distance between the two side plates 16 is smaller than the width of the bottom plate 15, which is conducive to the locking connection between the side plates 16 and the pull-out end plate 13 and the insertion end plate 14. At the same time, a first limiting structure 111 can be set at both ends of the insertion end plate 14. The first limiting structure 111 is a positioning hole 1111. The end of the slot rail 231 away from the insertion port 21 is connected to a baffle 4. The baffle 4 is against the insertion end 11 of the battery plug box 1. The baffle 4 serves as the end limit of the slot rail 231, ensuring that the battery plug box 1 can only reach a predetermined depth during the insertion process, avoiding collision with the back plate 26 of the battery cabinet 2. The baffle 4 is provided with a second limiting structure 221, which is a positioning pin 2211. When the battery compartment 1 is fully inserted, the positioning pin 2211 of the baffle 4 can be inserted into the positioning hole 1111 on the end plate 14, and the baffle 4 abuts against the insertion end plate 14 of the battery compartment 1. Optionally, in order to avoid the existence of useless space between the side plate 16 and the bottom plate 15, a triangular rib 17 is provided between the outer side of the side plate 16 and the bottom plate 15 to improve the strength of the battery compartment 1. Similarly, the pull-out end plate 13 and the insertion end plate 14 can also be provided with horizontal and vertical staggered reinforcing ribs, and multiple groove-like structures can be formed between the reinforcing ribs, which are more conducive to accommodating and hiding the screw heads and reducing the risk of loosening or damage due to collision.

[0046] Preferably, in this embodiment 1, the end of the positioning pin 2211 is provided with a chamfer. The chamfer of the end of the positioning pin 2211 can reduce the contact area with the entrance of the positioning hole 1111, thereby reducing the friction during insertion, making it easier and smoother for the positioning pin 2211 to enter the positioning hole 1111, playing a guiding role, guiding the positioning pin 2211 to enter the positioning hole 1111 in the correct direction, and helping to achieve more precise positioning; during the insertion process, the chamfer design can prevent the sharp edge of the positioning pin 2211 from scratching the inner wall of the positioning hole 1111, protecting the positioning hole 1111 from damage, improving the installation accuracy and reliability, and extending its service life.

[0047] In this embodiment 1, the axial direction of the positioning hole 1111 and the axial direction of the positioning pin 2211 are parallel to the slot track 231. Since the axial direction of the positioning hole 1111 and the axial direction of the positioning pin 2211 are parallel to the slot track 231, when the battery plug box 1 slides along the slot track 231, the positioning pin 2211 can smoothly enter the positioning hole 1111 without encountering unnecessary resistance or jamming, thereby ensuring the smoothness of the insertion process; more effectively limiting the freedom of movement of the battery plug box 1 in the slot 22, reducing its shaking in the vertical or horizontal directions, and the parallel arrangement structure can more evenly transfer and distribute the load, thereby improving the overall load-bearing capacity and impact resistance of the battery cluster.

[0048] In some embodiments, in order to improve the fixing effect of the battery plug box 1 after insertion, a first fixing structure 121 is provided at the pull-out end 12, and the slot track 231 is provided with a second fixing structure 211 corresponding to the first fixing structure 121. It should be noted that the correspondence here means that the second fixing structure 211 can be adapted to the first fixing structure 121, that is, the two can cooperate to achieve a fixing effect. The first fixing structure 121 and the second fixing structure 211 are fixedly connected. The cooperation between the first fixing structure 121 and the second fixing structure 211 can fix the pull-out end 12 and the insertion port 21 to prevent the battery plug box 1 from sliding out of the insertion port 21, and can effectively prevent the battery plug box 1 from shaking or falling off during transportation, installation or use, thereby enhancing the overall stability.

[0049] Preferably, one of the first fixing structure 121 and the second fixing structure 211 comprises a fixing screw hole 1211 and a fixing stud 2111 at the other end. A fixing screw 3 is installed between the fixing screw hole 1211 and the fixing stud 2111. The fixing screw 3 tightens the fixing screw hole 1211 and the fixing stud 2111, forming a high-strength connection. This connection method can withstand significant tensile and shear forces, ensuring the stability of the battery compartment 1 within the battery cabinet 2. The screw locking action effectively prevents loosening of the battery compartment 1 due to vibration, impact, and other factors during use, thereby improving the reliability of the connection. This also simplifies the installation and removal of the battery compartment 1, reduces maintenance difficulty and cost, and improves the maintainability of the equipment. The combined structure of the fixing screw hole 1211, fixing stud 2111, and fixing screw 3 is relatively simple, resulting in low manufacturing costs and contributing to improved product competitiveness. In this embodiment 1, in the recessed groove structure on both sides of the pull-out end plate 13, the part that fits with the bottom plate 15 is provided with a first fixing structure 121, and the first fixing structure 121 is a fixing hole, which passes through the bottom plate 15 and the pull-out end plate 13, and the slot 22 guide rail is provided with a second fixing structure 211 at one end close to the insertion port 21, and the second fixing structure 211 is a fixing stud 2111, and a fixing screw 3 is provided between the fixing hole and the fixing stud 2111, and the bottom plate 15, the pull-out end plate 13 and the slot 22 guide rail are fixed by the connection of the fixing screw 3 to achieve a fixing effect.

[0050] In other embodiments, the fixing holes of the first fixing structure 121 can also be provided at the bent portions at both ends of the pull-out end plate 13, and the fixing studs 2111 of the second fixing structure 211 can be provided on the side walls 23 of the battery cabinet 2. The pull-out end plate 13 is secured to the battery cabinet 2 via the fixing screws 3, achieving a secure fit. Optionally, a handle can be provided on the pull-out end plate 13 to facilitate the user in pulling out the battery compartment 1.

[0051] Therefore, the axial direction of the fixing screw hole 1211, the axial direction of the fixing stud 2111, and the axial direction of the fixing screw 3 are perpendicular to the slot track 231, ensuring that the battery plug box 1 can remain stable when subjected to lateral force, is not easy to deviate or shake, and reduces loosening and damage caused by vibration; the vertical axial direction enables the installer to clearly identify the correct installation direction when installing the fixing screw 3, thereby avoiding installation problems caused by incorrect direction; when the battery plug box 1 needs to be maintained or replaced, the vertically arranged fixing screw hole 1211 and fixing screw 3 make the disassembly process simpler and more direct.

[0052] In this embodiment 1, the distance between the corresponding guide ribs 232 on the two side walls 23 of the slot 22 is set to L1. It should be noted that the correspondence here refers to the two guide ribs 232 on the same horizontal plane as the two side walls 23. The distance between the two parallel sides of the insertion opening 21 and the side walls 23 is set to L2. The length of the insertion end 11 or the extraction end 12 of the battery compartment 1 is set to L3. Then, L2>L1=L3. Because L1 is equal to L3, when the battery compartment 1 is inserted into the slot 22, its sides will slide smoothly along the guide ribs 232 in the slot 22 until it is fully seated, avoiding installation difficulties or damage caused by positioning deviations. The design of L2 being greater than L1 provides sufficient space for the insertion of the battery compartment 1 and prevents jamming caused by over-sizing. This helps simplify the installation process and improve installation efficiency. When the battery compartment 1 is fully inserted into the slot 22, its sides will tightly fit with the guide ribs 232 in the slot 22, forming a stable connection. This design helps to reduce the shaking and displacement of the battery plug-in box 1 in the slot 22 and improve the reliability of the connection.

[0053] It should be noted that in some embodiments, within the slot 22, each battery compartment 1 corresponds to at least two slot rails 231, meaning that a battery compartment 1 is supported by at least two slot rails 231 located on the same horizontal plane. Each battery compartment 1 has at least two guide ribs 232 on either side of its insertion end 11 and its extraction end 12, preferably three to four guide ribs 232. With the support of at least two slot rails 231 and at least two guide ribs 232, the battery compartment 1 is more firmly supported within the slot 22. This multi-point support structure significantly improves the stability of the battery compartment 1 within the slot 22, preventing it from shaking or shifting when subjected to external forces. The design of multiple slot rails 231 and guide ribs 232 ensures that the battery compartment 1 is evenly supported during insertion, avoiding damage caused by excessive force at a single point. Furthermore, after the battery compartment 1 is fully inserted, its weight is better distributed, reducing the burden on a single support point.

[0054] The operating principle of the utility model is as follows:

[0055] The insertion end 11 of the battery plug box 1 is assembled toward the slot 22 in the insertion port 21. The number of battery plug cables that can be installed can be determined according to the number of slots 22. When the insertion end 11 of the battery plug box 1 is inserted into the insertion port 21, since L2 is greater than L1, it is convenient to align the insertion end 11 of the battery plug box 1. After entering the slot 22, the guide rib 232 guides the side panel 16 of the battery plug box 1 and gradually clamps it. When fully inserted, the positioning hole 1111 of the insertion end 11 of the battery plug box 1 can be connected with the positioning pin 2211 on the baffle 4. Due to the chamfered end of the positioning pin 2211, a secondary guiding and positioning effect is achieved. Subsequently, the fixing screw 3 is passed through the fixing hole and the fixing stud 2111 to further fix the battery plug box 1.

[0056] In summary, the battery cluster provided by the present invention has the following technical effects:

[0057] 1. Improved installation accuracy and efficiency: The slot track 231 and guide ribs 232 within the slot 22 provide a clear insertion path and guidance for the battery compartment 1, enabling smooth and accurate insertion into the cabinet's slot 22. This significantly reduces the need for multiple adjustments and reinsertions due to manual alignment errors, improving installation efficiency. Furthermore, the design of the guide ribs 232 ensures smooth sliding of the battery compartment 1 during insertion, reducing the risk of damage from friction and collision, and further improving the success rate of installation.

[0058] 2. Enhanced Stability: When the battery compartment 1 is fully inserted into the slot 22, the guide ribs 232 tightly contact the sides of the battery compartment 1, effectively limiting any movement of the battery compartment 1 within the slot 22. This secure connection improves the stability of the battery compartment 1 within the slot 22, ensuring it remains securely positioned even under vibration or impact. The coordinated use of the first limiting structure 111 and the second limiting structure 221 further enhances the securement of the battery compartment 1 within the slot 22, preventing displacement or dislodging during transportation or use. The guide ribs 232 provide dual guidance and positioning.

[0059] 3. Improved Safety: The stable connection structure of the battery box 1 reduces mechanical stress on the battery box 1 and its connecting components, reducing the probability of safety hazards such as cable breakage, poor contact, or short circuits.
