Description

Technical Field

[0001] This utility model relates to the field of energy storage equipment technology, and in particular to a battery cabinet. Background Technology

[0002] Existing energy storage battery cabinets suffer from numerous technical defects, exhibiting significant deficiencies in both structural design and electrical connections. Structurally, traditional battery cabinets have serious flaws in their battery module fixing methods, typically fixing only the front end and lacking effective fixing devices at the rear. This makes the battery modules prone to vibration during transportation, potentially damaging the internal structure of the battery pack and affecting overall product performance. Regarding electrical connections, high-voltage wiring harnesses are generally connected manually, which is not only cumbersome and time-consuming but also carries the risk of incorrect connections. Exposed cables also detract from the aesthetics of the equipment. In terms of safety protection, existing systems can only provide circuit break protection for the entire battery cluster. When any two or more battery modules within the cabinet experience a short circuit, the internal fuses of the modules will burn out, increasing subsequent maintenance costs and lacking an effective BMS protection strategy. Furthermore, the existing connection structure between the battery modules and the cabinet is poorly designed, failing to achieve quick and reliable plug-in fixing. The cable arrangement also suffers from technical problems such as excessive bending radii and poor heat dissipation. These defects severely impact the reliability, safety, and ease of maintenance of energy storage battery cabinets. Utility Model Content

[0034] The present invention will now be described in more detail with reference to the accompanying drawings, which illustrate preferred embodiments of the invention. It should be understood that those skilled in the art can modify the invention described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the scope of the invention.

[0035] In the description of this specification, terms such as "one embodiment" or "some embodiments" mean that one or more embodiments of this specification include a particular feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.

[0036] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0037] In existing technologies, energy storage battery cabinets generally adopt a front-fixed method, lacking an effective support structure at the rear. During transportation, battery modules are prone to displacement and vibration, leading to loosening of internal parts. High-voltage wiring harnesses require manual connection and assembly, posing a risk of misconnection, and exposed cables affect the aesthetics of the equipment. Traditional protection mechanisms rely on cutting off the entire circuit cluster, failing to provide independent protection for individual battery modules. When a short circuit occurs between modules, it can easily cause fuses to burn out, increasing maintenance costs.

[0038] To address the aforementioned issues, the researchers noted a correlation between missing tail-end fixing and defects in manual wiring. Analysis of the vibration transmission path revealed that bidirectional fixing effectively disperses mechanical stress. Based on this, a design approach combining electrical connection with mechanical fixing was proposed, employing a plug-in structure to simultaneously achieve power transmission and physical restraint. This integrated design not only replaces traditional cable connection methods but also forms multi-point support through structural coordination.

[0039] Therefore, this application proposes a battery cabinet including a battery module and a cabinet body. The battery cabinet according to an embodiment of this application is described below with reference to the accompanying drawings.

[0040] According to the embodiment of the present utility model, the battery cabinet 100, such as Figure 1 As shown, it includes: a battery module 1 and a cabinet 2. The battery module 1 is installed inside the cabinet 2. An opening 3 is provided on one end face of the cabinet 2, such as... Figures 2-4 As shown, the inner wall of the cabinet 2 away from the opening 3 is provided with a first plug-in part 4, and the battery module 1 is provided with a second plug-in part 5 on one end face along the first direction, which is corresponding to the first plug-in part 4. The first plug-in part 4 and the second plug-in part 5 are connected in cooperation.

[0041] The cabinet 2 refers to the rigid shell housing the battery module 1, which can be a combination of a metal frame and insulating material to ensure structural strength and electrical isolation. The opening 3 refers to the loading / unloading channel at the front end of the cabinet 2, the size of which can match the shape of the battery module 1 to facilitate installation along a straight path. The first plug-in part 4 refers to the conductive connection structure on the rear wall of the cabinet 2, specifically using an elastic buckle or guide groove structure, providing both power transmission and mechanical locking functions. The second plug-in part 5 refers to the docking component at the rear end of the battery module 1, which can be designed as a plug structure with conductive contacts, achieving precise alignment with the first plug-in part 4 through geometric matching. The first direction refers to the axial direction of the battery module 1 installation, usually consistent with the depth direction of the cabinet 2, ensuring that the plug-in structure completes docking along a preset trajectory.

[0042] Specifically, when the battery module 1 is pushed into the cabinet 2 along the opening 3, the second plug-in part 5 moves with the module to a position corresponding to the first plug-in part 4. Once the module reaches the preset installation depth, the conductive contacts of the second plug-in part 5 and the elastic latch of the first plug-in part 4 form an interference fit, establishing a stable electrical connection and limiting the axial displacement of the module through friction. This fit structure creates double constraints at both ends of the module; the front is limited by the edge of the opening 3, and the rear is locked by the plug-in part, effectively suppressing lateral swaying caused by transportation vibrations. The symmetrical design of the plug-in structure eliminates the need for manual angle adjustment during the connection process, thus eliminating the risk of wiring misalignment.

[0043] Compared to existing technologies, traditional solutions rely solely on front bolt fixation, leading to stress concentration. This solution utilizes a tail-end plug-in structure to create a distributed support structure, allowing vibration energy to be evenly dissipated along the cabinet frame 2. Existing cable connections require manual operation and occupy front space; this solution integrates power transmission into the plug-in structure, completing the connection process simultaneously with mechanical installation. Traditional protection mechanisms rely on external relays to cut off the entire circuit cluster; this solution achieves module-level protection through independent on / off switching of the plug-in section.

[0044] Through the above technical solutions, the tail of the battery module 1 is effectively mechanically fixed to prevent damage during transportation; the plug-in structure replaces exposed cables, improving the aesthetics of the equipment; and the automated docking process eliminates manual wiring errors. The module-level electrical connection structure can independently cut off the circuit under abnormal operating conditions, preventing the fault from spreading to the entire battery pack. The bidirectional fixing design reduces vibration amplitude and ensures the integrity of the internal structure of the battery pack.

[0045] In some embodiments of this utility model, such as Figures 1-3 As shown, it also includes a bracket 6, which is installed inside the cabinet 2 and located on opposite side walls inside the cabinet 2. The battery module 1 is installed on the bracket 6.

[0046] The bracket 6 refers to the support structure that supports the battery module 1. Specifically, it can be made of welded metal profile frame or stamped sheet metal bending parts, and its two sides are symmetrically installed on the inner wall of the cabinet 2 to form a stable support surface. The two opposite side walls inside the cabinet 2 refer to two opposing mounting surfaces arranged along the length of the battery module 1. Specifically, the bracket 6 can be fixed by pre-embedded mounting seats or bolt fastening, forming a bidirectional constraint support structure.

[0047] Specifically, the bracket 6 extends longitudinally along the inner walls of both sides of the cabinet 2 to form a continuous load-bearing track, and the bottom of the battery module 1 has a matching mounting groove on the contact surface with the bracket 6. When the battery module 1 is pushed into the cabinet 2 along the length of the bracket 6, the guide structures on both sides of the bracket 6 restrict the lateral displacement of the battery module 1, and the mounting groove and the snap-fit ​​structure of the bracket 6 form a vertical constraint. The front end of the battery module 1 is connected to the rear wall of the cabinet 2 through a plug-in part, and the rear end is supported by the brackets 6 on both sides to form a three-point fixing system. During transportation vibration, the longitudinal stress is dispersed by the bidirectional brackets 6, and the lateral vibration energy is offset by the friction of the bottom contact surface.

[0048] Compared to existing technologies, traditional solutions only provide a single-point fixation at the front end of the battery module 1, resulting in a lack of effective support at the rear and causing stress concentration at the front connection point during vibration. This solution, by symmetrically arranging the brackets 6 on both sides of the cabinet 2 to form a distributed support structure, provides the battery module 1 with more than two support points along its length. Vibration energy is absorbed synchronously by the brackets 6 on both sides, avoiding stress concentration caused by single-point fixation.

[0049] Through the above technical solution, this application effectively solves the problem of internal structural damage to the battery module 1 caused by vibration during transportation. The symmetrical support structure formed by the two side brackets 6 provides balanced constraint force to the battery module 1 along its length. When encountering longitudinal vibration, the vibration energy is synchronously transmitted to the cabinet 2 frame through the two side brackets 6, while lateral vibration is consumed by the frictional damping of the contact surface between the brackets 6 and the battery module 1, thus achieving synchronous suppression of multi-dimensional vibration.

[0050] In some embodiments of this utility model, such as Figures 7-10 As shown, it also includes a slider 8. The bracket 6 is provided with a sliding groove 7 along the extending direction of the bracket 6. The slider 8 is movably mounted on the bracket 6 and cooperates with the sliding groove 7. The slider 8 is mounted on the bottom wall of the battery module 1 so that the battery module 1 can move on the bracket 6 along the extending direction of the sliding groove 7.

[0051] The groove 7 refers to a strip-shaped groove formed on the surface of the bracket 6, which can be achieved by machining or stamping. The groove extends in the same direction as the length of the bracket 6, guiding the movement trajectory of the sliding member 8. The sliding member 8 is a mechanical component that matches the shape of the groove 7, and can be implemented as a metal slider or roller structure. It achieves positioning by embedding itself inside the groove 7. Figure 4 , Figure 5 , Figure 8As shown, the sliding member 8 is provided with a connecting hole 28, and the edge of the battery module 1 is provided with a second through hole 29 corresponding to the connecting hole 28. The fastener passes through the connecting hole 28 and the second through hole 29 to fix the sliding member 8 on the bottom wall of the battery module 1.

[0052] Specifically, the slide groove 7 is arranged along the extending direction of the bracket 6, forming a physical constraint on the movement path of the sliding member 8. After the sliding member 8 is embedded in the slide groove 7, the bottom wall of the battery module 1 is fixedly connected to the sliding member 8, allowing the module to translate along the extending direction of the slide groove 7. The side wall of the slide groove 7 restricts the lateral displacement of the sliding member 8, and the bottom of the slide groove 7 restricts the vertical displacement of the sliding member 8. During transportation, the cooperation between the slide groove 7 and the sliding member 8 converts the vibration of the battery module 1 into a small displacement along the direction of the slide groove 7, while the rigid support of the side wall of the slide groove 7 suppresses lateral vibration.

[0053] The slider 8 can be configured as a slider structure, such as... Figure 10 As shown, a protrusion 26 is formed on one end face of the slider. The protrusion 26 is engaged with the opening of the slide groove, and the end face of the protrusion 26 is flush with the upper surface of the opening of the slide groove. That is, the coating end face of the slider is fixedly connected to the bottom wall of the battery module. The battery module mounted on the bracket is supported by the slider and the bracket, and the load-bearing capacity of the battery module is simultaneously supported by the slider and the bracket. This avoids stress concentration on the slider or bracket, which could damage the surface of the battery module and improves the overall structural stability of the battery cabinet.

[0054] Compared with existing technologies, the existing battery module 1 is only fixed at the front end, with no constraint at the rear end, resulting in free swinging of the rear end of the module during vibration. This solution, through the mechanical cooperation of the slide groove 7 and the sliding member 8, forms a fixed structure at the rear end. The sidewall of the slide groove 7 directly bears the lateral stress generated by vibration, while the degree of freedom of movement of the sliding member 8 avoids stress concentration caused by rigid fixation.

[0055] Through the above technical solution, this application achieves effective fixation of the tail of the battery module 1 during transportation. The cooperation structure between the slide groove 7 and the sliding member 8 converts vibration energy into controllable linear displacement, suppressing internal structural damage caused by tail swing. At the same time, the mobility of the sliding member 8 along the slide groove 7 retains the positioning adjustment capability during module installation, avoiding assembly difficulties caused by excessive tightness.

[0056] In some embodiments of this utility model, such as Figures 7-9 As shown, it also includes a drive component 9, which is installed inside the cabinet 2 and connected to the slider 8 to drive the slider 8 to move on the slide groove 7.

[0057] The drive component 9 refers to a mechanical device capable of outputting linear or rotational power, specifically an electric actuator or servo motor. It receives operating commands via electrical control signals and converts them into mechanical displacement output. This device directly transmits driving force to the moving mechanism, replacing the traditional manual push-pull operation mode.

[0058] Among them, such as Figure 9 As shown, the drive assembly 9 includes a power component 23, a mounting bracket 24, and a transmission component 25. The connection between the power component 23 and the sliding component 8 refers to the power transmission interface, which can be achieved by using a gear and rack meshing, a lead screw and nut drive, or a traction cable winding mechanism, etc., as described in the transmission component 25, to convert the rotational motion of the power component 23 into the linear displacement of the sliding component 8. The power component 23 is mounted on the mounting bracket 24 and can be directly mounted on and connected to the sliding component 8, driving the sliding component 8 to move on the slide groove 7. The direct connection between the drive assembly 9 and the sliding component 8 reduces the need for a transmission assembly, simplifies the internal structure of the battery cabinet 100, reduces the installation difficulty of the internal structure of the battery cabinet 100, and lowers maintenance costs.

[0059] Specifically, the power output end of the drive component 9 is rigidly connected to the sliding member 8 through a transmission mechanism. When the drive component 9 receives a control signal, the output shaft generates axial displacement or rotational motion, driving the sliding member 8 to move linearly along the extension direction of the slide groove 7. The fixed connection between the sliding member 8 and the battery module 1 ensures that the entire module moves synchronously with the sliding member 8. The extension direction of the slide groove 7 is parallel to the direction from the opening 3 of the cabinet 2 to the first insertion part 4, ensuring that the second insertion part 5 and the first insertion part 4 remain aligned during the movement of the battery module 1. Under abnormal operating conditions, such as when the cell temperature exceeds a threshold or the current is abnormal, the control unit of the energy storage system can trigger the drive component 9 to move in the opposite direction, causing the battery module 1 to retract a predetermined distance along the slide groove 7, thereby physically separating the second insertion part 5 from the first insertion part 4.

[0060] Compared to existing technologies, traditional battery cabinets 100 rely on operators to manually push and pull the battery modules 1 for position adjustment. This results in uneven force application leading to positioning deviations and uncontrollable movement speed, and also fails to provide automatic circuit breaker protection in abnormal conditions. This solution replaces manual operation with a mechanical drive system, eliminating positioning errors caused by human factors. Furthermore, in the event of an electrical connection abnormality, a preset program can control the module to quickly disconnect, preventing short-circuit current from damaging the fuse.

[0061] Through the above technical solution, this application achieves automated positioning control of the battery module 1 within the cabinet 2, solving the problems of low efficiency and poor positioning accuracy of manual operation, and providing an execution foundation for remote control and intelligent management systems. When an electrical abnormality is detected, the drive system can actively disconnect the electrical connection path between the battery module 1 and the cabinet 2, avoiding protection delays caused by manual intervention, reducing maintenance costs, and improving system safety.

[0062] In some embodiments of this utility model, such as Figures 11-13 As shown, the first insertion part 4 includes a first base 10, a first sealing member 11, and a first connector 12. The first sealing member 11 is mounted on the first base 10. A groove 13 is provided on one inner wall of the first sealing member 11. A first through hole 15 is provided on the inner wall of the first sealing member 11 away from the groove 13. The first connector 12 passes through the first through hole 15 and is engaged in the groove 13. An opening 14 is formed at one end of the first sealing member 11 away from the base. The second insertion part 5 passes through the opening 14 and is inserted into the first insertion part 4 and electrically connected to the first connector 12.

[0063] The first base 10 refers to the base component that supports the plug-in structure. Specifically, it can be made of metal casting or injection molding and is used to provide rigid support for the first sealing element 11 and the first connecting element 12.

[0064] The first sealing element 11 refers to an insulating component with a guiding structure, which can be injection molded from silicone or rubber material. The groove 13 provided on its inner wall is used to constrain the lateral displacement of the first connecting element 12, and the first through hole 15 is used to control the installation path of the first connecting element 12.

[0065] The groove 13 refers to a groove structure set on the inner wall of the seal, which can be implemented by a trapezoidal cross section or a dovetail groove structure, and is used to restrict the circumferential movement of the first connector 12.

[0066] The first through hole 15 refers to a channel that penetrates the side wall of the seal. Specifically, it can be implemented by a through hole that matches the outer contour of the first connector 12. Its axial direction forms a spatial intersection with the extension direction of the slot 13, which is used to guide the insertion path of the first connector 12.

[0067] The first connector 12 refers to the conductive connector 16, which can be implemented using a copper alloy spring or spring pin structure. It is installed by passing through the first through hole 15 and embedding into the slot 13 to form a two-degree-of-freedom constraint.

[0068] The opening 14 refers to the conical flared structure formed at the end of the sealing element. Specifically, it can be implemented by using the trumpet-shaped opening 3 with a gradually changing diameter to guide the insertion trajectory of the second insertion part 5. Alternatively, it can be a circular opening 3 with a constant diameter, or a square opening 3 with a constant side length. Of course, other opening 3 structures that can achieve the above functions can also be used, which will not be elaborated here.

[0069] Specifically, the first base 10 is bolted to the inner wall of the cabinet 2. The first base 10 can also be fixed using other methods that achieve the same function, which will not be elaborated here. The first sealing element 11 is installed on the base surface via an interference fit. After the first connecting element 12 is inserted into the first through hole 15 at an inclined angle, its end is embedded in the slot 13 to form a mechanical lock. When the second insertion part 5 is inserted along the tapered guide surface of the opening 14, its conductive contacts form surface contact with the elastic contact portion of the first connecting element 12. The elastic deformation of the first sealing element 11 forms an annular sealing band at the insertion interface, preventing external foreign objects from entering the contact area. The staggered spatial arrangement of the slot 13 and the first through hole 15 prevents the first connecting element 12 from rotating circumferentially under vibration loads, ensuring the stability of the contact pressure.

[0070] It should be noted that the first base 10 can be screwed onto the inner wall of the cabinet 2 using fasteners such as bolts and screws. The first base 10 can also be snapped onto the inner wall of the cabinet 2 using clips, which will not be described in detail here. The first sealing element 11 and the first base 10 can be fixed by interference fit. The first sealing element 11 can also be integrally formed with the first base 10. The first sealing element 11 can also be fixed by other connection methods that can achieve the above functions, which will not be described in detail here.

[0071] Compared to existing technologies, the current battery cabinet 100 uses an open cable connection method, requiring manual insertion of each cable. This solution, however, achieves blind-plug connection through a modular plug-in structure, eliminating the risk of manual wiring errors. In traditional solutions, exposed cable connectors are susceptible to environmental corrosion. This solution, through the integrated design of the sealing element and plug-in structure, forms a physically isolated sealed cavity at the electrical connection interface. In existing technologies, floating connectors are prone to poor contact under vibration. This solution, through the dual positioning mechanism of the slot 13 and the through-hole, mechanically constrains the conductive components in three axes.

[0072] Through the above technical solution, this application achieves tool-less plug-in installation of the battery module 1 and the cabinet 2, allowing electrical connection to be completed without identifying the wiring sequence during operation. The closed design of the plug-in structure hides all conductive components within the sealed cavity, eliminating safety hazards caused by exposed cables. The elastic contact method of the first connector 12 maintains stable contact resistance during long-term use, preventing electrical connection failure due to vibration. The integrated design of the sealing element and the plug-in structure achieves an IP54 protection rating while reducing the overall thickness of the connector, meeting the compact layout requirements of the battery cabinet 100.

[0073] In some embodiments of this utility model, such as Figures 2-3 As shown, the inner wall of the cabinet 2 away from the opening 3 is provided with a conductive connection part 16. The conductive connection part 16 is connected to the end of the first connector 12 away from the first seal 11. The conductive connection part 16 connects multiple first plug-in parts 4 in series.

[0074] The conductive connection part 16 refers to the conductive structure installed on the inner wall of the cabinet 2, which can be implemented using copper busbars or conductive rails. An insulating coating can be applied to its surface to prevent short circuits. This structure replaces traditional exposed cables with physical contact, forming an internal circuit conduction path and reducing manual wiring steps.

[0075] In this context, "series connection" refers to multiple first plug-in portions 4 forming independent branches in a parallel circuit through the conductive connection portion 16, which can be implemented using a parallel topology. Each branch corresponds to a single battery module 1, forming an independent on / off control unit, so that disconnecting any branch does not affect the current transmission of other branches.

[0076] Specifically, the conductive connection part 16 is embedded in the inner wall of the cabinet 2 and forms a rigid connection with the end of the first connector 12, eliminating the need for flexible bending of the cable. Multiple first plug-in parts 4 form a series fulcrum in a parallel circuit through the conductive connection part 16, with the first connector 12 in each branch acting as a conductive contact and directly connected to the conductive connection part 16. When a battery module 1 malfunctions, the first connector 12 in the corresponding branch can be cut off by a fuse mechanism or electronic switch, disconnecting only that branch while maintaining normal operation of other branches. The continuous arrangement of the conductive connection parts 16 integrates the originally scattered electrical contacts into a linear layout, avoiding manual plugging operations while completely concealing the cable inside the cabinet 2.

[0077] Compared to existing technologies, which rely on manual insertion of exposed cables to connect modules, resulting in large cable bending radii and the risk of incorrect insertion, this solution integrates the electrical connections into the cabinet 2 via the built-in conductive connection part 16 and a series structure, eliminating the problem of exposed cables. Existing technologies can only control the on / off state of the entire circuit cluster via relays, while the series branch structure of this solution allows each module to form an independent protection unit, isolating faulty modules without interrupting the overall circuit.

[0078] Through the above technical solution, this application avoids connection errors caused by manual plugging operations, hides cables to improve the aesthetics of the equipment, and simultaneously achieves independent on / off control of each individual battery module 1, reducing system downtime caused by cluster outages. Faulty modules can be isolated individually through a branch disconnection mechanism to prevent short-circuit current from impacting other modules, reducing the probability of fuse burnout and maintenance costs.

[0079] In some embodiments of this utility model, such as Figure 12 , Figure 14 As shown, the second plug-in part 5 includes a second base 17, a second connector 18, and an adapter 19. The two second connectors 18 are mounted on the second base 17 perpendicular to the end face of the second base 17. The adapter 19 is mounted on the end face of the second base 17 away from the second connectors 18 and passes through the second base 17 to connect with the two second connectors 18. The adapter 19 is fixedly connected to the battery module 1.

[0080] The second base 17 refers to the mounting base that supports the second connector 18 and the adapter 19. It can be made of die-cast aluminum alloy and machined to form a flat mounting surface. The second connector 18 is a metal conductor used to establish an electrical connection. It can be made of copper busbar with a silver-plated surface to reduce contact resistance. The adapter 19 is a composite structure that achieves both mechanical fixation and electrical connection. It can be made of a copper connecting post with a threaded hole, its length being sufficient to penetrate the second base 17 and be threadedly locked to the battery module 1 housing.

[0081] Specifically, the two second connectors 18 are symmetrically distributed vertically on the second base 17, forming a stable support structure. When the second insertion part 5 mates with the first insertion part 4, the vertical arrangement of the second connectors 18 can simultaneously resist lateral vibration and longitudinal displacement. The adapter 19 passes through the base and is rigidly connected to the battery module 1 housing, achieving a secure fixation on the battery module 1. During the insertion process, the contact surfaces of the second connector 18 and the first insertion part 4 form a conductive path. While providing mechanical fixation, the adapter 19 allows current to flow between the battery module 1 and the conductive connection part 16 through its internal conductor. During installation, when the second insertion part 5 is fully inserted into the rear of the cabinet 2, the threaded connection structure of the adapter 19 ensures a rigid connection between the tail of the battery module 1 and the cabinet 2.

[0082] Compared to existing technologies, traditional battery modules 1 are only fixed at a single point at the front, lacking effective constraint at the rear. This solution, however, uses the adapter 19 of the second connector 5 to form a rear fixing point, combined with the vertical support of the two second connectors 18, to construct a bidirectional fixing structure. Existing technologies require manual insertion of each cable individually; this solution integrates the power connection into the connector structure, achieving automatic alignment and connection through the combination of the second connectors 18 and the adapter 19. Existing battery modules 1 lack a dedicated fixing structure at the rear; the threaded connection between the adapter 19 and the battery module 1 in this solution can withstand high-frequency vibrations during transportation.

[0083] Through the above technical solution, the tail of the battery module 1 is rigidly connected to the cabinet 2 via the adapter 19, preventing internal parts from loosening due to transportation vibration. The vertical layout of the second connector 18 and the through-type design of the adapter 19 enable the plug-in part to simultaneously provide electrical connection and mechanical fixation functions, eliminating the risk of manual wiring errors. The through-type connection structure between the adapter 19 and the second base 17 achieves the fixation of the tail of the battery module 1 within a limited space, solving the stress concentration problem caused by the tail being suspended in the traditional solution. The combined design of the second connector 18 and the adapter 19 integrates the power cable connection into the plug-in action, achieving simultaneous completion of electrical connection and mechanical fixation.

[0084] In some embodiments of this utility model, such as Figure 11 , Figure 14 As shown, a insertion tooth 20 is formed on one end face of the second connector 18, and the end faces of the two second connectors 18 with the insertion tooth 20 are arranged opposite each other. The two second connectors 18 are inserted into the first seal 11 and the first connector 12 is inserted between the two insertion teeth 20.

[0085] The insertion tooth 20 refers to the protruding structure formed on the end face of the second connector 18, which can be implemented by a sawtooth or trapezoidal structure. This structure can form a mechanical engagement with the first connector 12 to prevent lateral displacement.

[0086] The relative arrangement refers to the symmetrical arrangement of the end faces of the insertion teeth 20 of the two second connectors 18. Specifically, it can be achieved by using a mirror symmetrical assembly method to form a symmetrical insertion guide space and avoid reverse insertion.

[0087] The "between the insert teeth 20" refers to the clamping area formed by the first connector 12 inserting into two of the insert teeth 20. Specifically, this can be achieved through a bidirectional limiting structure, which increases friction and limits longitudinal displacement by utilizing tooth surface contact.

[0088] Specifically, the insertion teeth 20 are configured as a symmetrically distributed guide structure, allowing only correct insertion in one direction during the insertion process. Reverse insertion results in physical obstruction due to the interference between the insertion teeth 20 and the contour of the first seal 11. When the first connector 12 is inserted between two insertion teeth 20, the tooth surfaces of the insertion teeth 20 form surface contact with the surface of the first connector 12, suppressing relative sliding caused by vibration through friction between the tooth surfaces. Simultaneously, the protruding portions of the insertion teeth 20 embed into the recessed areas on both sides of the first connector 12, forming a mechanical interlock. The design of simultaneously inserting two second connectors 18 into the first seal 11 creates a redundant current path, ensuring circuit continuity even if one insertion tooth 20 has poor contact.

[0089] Compared to existing technologies, current plug-in structures lack guiding features to prevent incorrect insertion, relying solely on manual alignment, which carries the risk of incorrect insertion direction. This solution, however, uses symmetrically arranged plug teeth 20 to forcibly define the insertion direction. Existing connectors use a single-point contact method, which is prone to contact failure due to stress concentration under vibration conditions. This solution, however, disperses stress through a bidirectional clamping structure and suppresses displacement through mechanical interlocking. Existing technologies lack redundant conductive paths, meaning a single-point failure leads to circuit interruption. This solution, however, achieves multi-path conduction through synchronous plugging of two connectors.

[0090] Through the above technical solutions, this application can eliminate the risk of incorrect orientation during manual insertion and ensure the uniqueness of the connection orientation; enhance connection stability through the bidirectional clamping action of the insertion teeth 20 and reduce poor contact caused by vibration; improve circuit reliability through redundant conductive paths and avoid safety hazards caused by single-point failure.

[0091] In some embodiments of this utility model, such as Figure 11 , Figure 14As shown, a limiting part 21 is provided on the edge of one end face of the second base 17 near the second connector 18, and the inner wall of the limiting part 21 is configured to cooperate with the outer contour of the first sealing member 11.

[0092] The limiting part 21 refers to a protrusion or groove structure provided on the edge of the second base 17, which can be implemented by an annular flange or a U-shaped groove 13, and its inner wall shape complements the outer surface of the first sealing member 11. The outer contour of the first sealing member 11 refers to the geometric shape formed by the outer surface of the first sealing member 11, which can be implemented by a polygonal cross section or a cylindrical structure with guide chamfers.

[0093] Specifically, when the second insertion part 5 moves toward the first insertion part 4, the inner wall of the limiting part 21 contacts the outer surface of the first sealing member 11 to form a sliding guide. As the insertion depth increases, the inner wall of the limiting part 21 slides along the outer contour of the first sealing member 11, forcing the insertion teeth 20 of the second connector 18 to remain coaxially aligned with the first connector 12. In the completed insertion state, the inner wall of the limiting part 21 completely wraps around the outer periphery of the first sealing member 11, forming a three-dimensional spatial constraint, preventing the second insertion part 5 from undergoing lateral displacement or circumferential rotation relative to the first insertion part 4.

[0094] In some specific embodiments, the inner wall of the limiting part 21 may be provided with a guide slope, which engages with the chamfer of the outer contour of the first sealing member 11 to form a progressive positioning. When an initial angular deviation occurs during the insertion process, the guide slope automatically corrects the second insertion part 5 to a predetermined trajectory.

[0095] Compared to existing technologies, traditional plug-in structures rely on visual alignment by operators, which can easily lead to misalignment of the plug teeth 20 and the connector due to visual errors. This solution replaces manual alignment with a mechanical limiting structure, automatically eliminating positional deviations during the plugging process. In existing technologies, the plug-in part maintains the connection only through friction, which is prone to loosening under vibration. In contrast, the circumferential wrapping structure of this solution creates multiple physical constraints, significantly improving vibration resistance.

[0096] Through the above technical solution, this application achieves an automatic positioning and correction function during the insertion process, eliminating the risk of connection misalignment caused by manual operation. During equipment operation, the limiting part 21 and the outer contour of the seal form a rigid support, effectively suppressing the relative displacement of the insertion part under vibration environment and avoiding the decrease in conductivity caused by wear of the contact surface. This structure also ensures that the sealing surface of the insertion part is completely fitted after connection, preventing insulation failure caused by dust or liquid intrusion.

[0097] In some embodiments of this utility model, such as Figure 14As shown, the second plug-in portion 5 also includes an insulating member 22, which is mounted on the second connector 18 and is disposed away from the end face where the plug-in tooth 20 is located.

[0098] The insulating component 22 refers to the insulating protective structure covering the non-contact area of ​​the second connector 18. Specifically, it can be molded from polyvinyl chloride or rubber material and fixed to the surface of the second connector 18 by snap-fit ​​or adhesive, in order to block the conductive contact path in the non-plug area.

[0099] The setting of avoiding the end face where the plug tooth 20 is located means that the edge contour of the insulating member 22 is kept at a distance from the end face of the plug tooth 20. Specifically, the avoidance notch can be formed by stamping or laser cutting process to keep the end face of the plug tooth 20 exposed and ensure that the plug tooth 20 forms effective electrical contact with the first connector 12.

[0100] Specifically, the insulating component 22 is assembled in the main body area of ​​the second connector 18, extending its coverage to the sidewalls and back of the second connector 18. However, the design of the avoidance notch ensures that the end face of the insertion tooth 20 is fully exposed. When the battery module 1 is inserted into the cabinet 2, the end face of the insertion tooth 20 directly contacts the first connector 12 to form a circuit connection, while the conductive surface of the remaining part of the second connector 18 is completely covered by the insulating component 22, preventing unintended contact between adjacent conductive components under vibration or accidental contact. The avoidance design of the insulating component 22 achieves local insulation while preserving the effective contact area between the insertion tooth 20 and the first connector 12, avoiding increased insertion resistance or poor contact due to interference from the insulating material.

[0101] Compared with existing technologies, the conductive connection parts 16 of the existing energy storage battery cabinet 100 are usually designed to be completely exposed, which can easily cause short circuits due to operational errors or component displacement during the insertion process. This solution, by selectively setting the insulating parts 22 in non-contact areas, not only eliminates the risk of operators accidentally touching live parts, but also maintains the functional integrity of the conductive contact surface through precise avoidance design, thus resolving the contradiction between insulation protection and conductivity performance in traditional solutions.

[0102] The energy storage system according to the present invention uses the battery cabinet 100 described above.

[0103] Specifically, the energy storage system includes a fire suppression system and a cooling system. The fire suppression system monitors the internal environment of the cabinet 2. When the battery module 1 experiences thermal runaway, the fire suppression system controls the drive assembly 9 to drive the sliding member 8 to move a specified distance away from the inner wall of the cabinet 2, separating the first plug-in part 4 from the second plug-in part 5. This prevents the battery module 1 from further aggravating its thermal runaway. Simultaneously, the fire suppression system extinguishes fires inside the cabinet 2, reducing losses to the battery cabinet 100 and improving its safety performance. The cooling system cools the internal environment of the battery cabinet 100, further avoiding the risk of thermal failure of the battery module 1 and improving its safety performance.

[0104] In summary, such as Figure 1-14 As shown, an embodiment of a battery cabinet includes a battery module, a cabinet body, a bracket, a slider, a motor, a gear chain mechanism, a socket, a plug, and an energy storage system.

[0105] The brackets are installed on opposite sides of the inner wall of the cabinet. The battery module is supported on the brackets. The brackets are provided with a sliding groove. The slider is installed in the sliding groove and moves along the extension direction of the sliding groove. The slider has the protrusion 26, which is engaged with the opening of the sliding groove and is flush with the outer upper surface of the sliding groove.

[0106] The bottom of the slider engages with a gear chain mechanism, and a motor is mounted at one end of the gear chain mechanism to drive the slider connected to the gear chain mechanism to move.

[0107] The cabinet has sockets on its inner wall, with multiple sockets arranged on the inner wall and connected by connecting wires to ensure smooth circuit. One end of the battery module has a plug that mates with the socket. The battery module is installed inside the cabinet and the plug and socket are connected.

[0108] It also includes the high-voltage box assembly 27, which is mounted on the bottom wall inside the cabinet and has a plug. The plug on the high-voltage box assembly 27 is plugged into a socket on the inner wall of the cabinet to electrically connect the high-voltage box assembly 27 to the battery module.

[0109] The slider has a connection hole, through which it is screwed to the battery module.

[0110] The energy storage system is electrically connected to the motor.
