[0031] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0032] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0033] As a carrier of highly integrated power equipment, energy storage containers contain critical components such as battery packs and power distribution modules. Daily inspections, maintenance, and debugging require a clear view; therefore, a container shell equipped with automatic illumination is needed. This ensures operational accuracy and avoids problems such as missed wiring checks and misjudgments of component status due to insufficient lighting.

[0034] Existing lighting designs typically involve installing the lights on the inner top of the container as a whole lighting unit, controlled by a lighting switch to provide overall lighting for the container. However, the electrical components and other control equipment located below these lights can obstruct the diffusion of light, creating blind spots and affecting the lighting range, thus failing to meet the needs of daily use and maintenance.

[0035] This application provides a container shell and an energy storage container. The container shell contains an automatically extending lighting mechanism specifically designed for energy storage containers. This mechanism extends outwards when the container doors are opened, meeting the container's lighting needs and ensuring the efficiency and accuracy of personnel operations. It provides ample light for internal maintenance, inspection, and equipment debugging, eliminating blind spots and helping personnel clearly identify component status and wiring details, avoiding operational errors caused by visual biases, and improving daily maintenance and troubleshooting efficiency. It also enhances safety protection capabilities by providing critical lighting support for personnel evacuation and emergency fault diagnosis, reducing the probability of safety accidents. Furthermore, it improves ease of use and cost-effectiveness by supporting automatic door opening and closing, allowing personnel to control the lighting without manual operation, simplifying the usage process and reducing long-term operating costs.

[0036] In a first aspect, the enclosure 1000 of this application includes: enclosure body 600, enclosure door 100, and lighting device 200.

[0037] like Figures 1-4As shown, the housing 600 defines a receiving cavity 400, which is an independent space inside the housing for accommodating goods or equipment. It can realize the effective utilization and functional zoning of the internal structure, and provide structural support and protection functions. The interior of the receiving cavity 400 can be used to install structural components such as battery packs and power distribution modules.

[0038] One end of the container 600 has an opening that communicates with the receiving cavity 400. The container body can be made of aluminum alloy, steel, or fiberglass, depending on the material. The opening 500 communicating with the receiving cavity 400 includes a standard opening, a side opening, and a roof opening. The container door 100 is movably located at the opening 500 to open or close the receiving cavity. The opening method of the container door 100 can be sliding, flipping, folding, or hinged.

[0039] For example, the box body 600 has an opening at one end along its length, and the box door 100 can be hinged to one side edge of the opening 500 in the left-right or up-down direction to open or close the receiving cavity 400; or, the box door 100 can be translated relative to the box body 600 to open or close the opening.

[0040] The lighting device 200 may include a retractable assembly 210 and a lighting assembly 220. The retractable assembly 210 is movably disposed in the housing 600. For example, the retractable assembly 210 may be disposed in the receiving cavity 400 of the housing 600 and adjacent to the opening 500. The retractable assembly 210 may be disposed on the top wall, bottom wall, left side wall or right side wall of the receiving cavity 400, and the retractable assembly 210 may rotate, translate or move in other ways relative to the housing 600.

[0041] The lighting component 220 is mounted on the retraction component 210, allowing it to move with the retraction component 210 to adjust its lighting position, direction, and range. The lighting component 220 may include a light-emitting element 221 and a lampshade 222, with the lampshade 222 located outside the light-emitting element 221 to provide rain and sun protection. The retraction component 210 can be driven by a door or by a separately equipped drive unit. In the latter case, the independent drive unit can be electrically controlled to move the retraction mechanism after a sensor detects the door is open.

[0042] In the open state, the retractable assembly 210 extends the lighting assembly 220 outside the receiving cavity 400 to meet lighting needs; in the closed state, the retractable assembly retracts the lighting assembly 220 into the receiving cavity 400 to realize the storage function of the lighting assembly.

[0043] The enclosure 1000 provided in this application has a lighting device 200, including a retractable assembly 210 and a lighting assembly 220. When the enclosure door 100 is opened, the retractable assembly 210 can extend the lighting assembly 220 out of the receiving cavity 400, which can expand the lighting range and solve the problems of blind spots and limited lighting range of existing internal lighting, achieving efficient operation and facilitating daily use and maintenance needs. At the same time, when the enclosure door 100 is closed, the lighting assembly 220 will retract into the receiving cavity 400 of the enclosure 1000 along with the retractable assembly 210, which can also achieve the protection effect of the lighting assembly 220. In addition, it can also improve the ease of use and economy, simplify the use process, and reduce long-term use costs.

[0044] In some embodiments, combined with Figure 1 The retractable assembly 210 is connected to the door 100 via a transmission. The retractable assembly is adapted to move relative to the box body under the drive of the door. In other words, when the door 100 is opened or closed, it can drive the retractable assembly 210 to move, thereby realizing the extension or retraction of the lighting assembly 220 and realizing the driving function of the door 100.

[0045] The enclosure doors 100 include: latch-type doors, double-leaf louvered doors, and single-leaf doors. The latch-type escape doors adopt an outward opening design, which meets the requirements of fire-resistant partitions. The double-leaf louvered doors can be used in equipment areas such as power distribution compartments, and adopt a combination design of double louvered doors and ventilation louvers to meet the needs of equipment heat dissipation and access. The single-leaf doors can be used in areas such as battery compartments, and adopt a common single-leaf door structure, which has basic anti-theft and waterproof functions.

[0046] When the container door 100 is opened, the door 100 extends the retraction assembly 210 outwards; when the container door 100 is closed, the door 100 retracts the retraction assembly 210 inwards. The lighting device 200 of the energy storage container can retract to the inside of the container. Thus, when the container door 100 is open, the retraction assembly 210 can extend the lighting device 220 out of the receiving cavity 400, expanding the lighting range and solving the problem of blind spots and limited lighting range in existing internal lighting. Furthermore, it improves space utilization: integrating the lighting device into the container interior avoids external hanging or independent installation, reducing the occupation of external space and maximizing the use of internal space. It also ensures safety: the lighting device, protected by the container shell, is protected from external factors (such as rain and dust), and a suitable lighting environment is maintained through a temperature system, extending the equipment's service life.

[0047] In some embodiments, combined with Figure 1The door 100 is hinged to the body 600 at one end along a first direction, which is perpendicular to the axis of the opening. The first direction is the left-right direction. A hinge is a mechanical structure that connects two objects using a hinge, allowing the connected objects to rotate relative to each other within a limited range. It is commonly used for connecting components in machinery, vehicles, doors, and windows.

[0048] The connection between the door 100 and the enclosure 600 must meet electrical safety specifications and mechanical strength requirements, balancing functionality and safety. On one hand, it must meet electrical connection specifications: the door and metal frame must be bridged by a yellow-green insulated copper core flexible wire, meeting cross-sectional area requirements and clearly marked. On the other hand, it must meet mechanical structural design requirements, possessing strong connecting components, good sealing performance, and excellent compatibility with energy storage systems.

[0049] In some embodiments, combined with Figures 2-4 The retractable assembly includes: a slide rod 212, a transmission rod 211, a first connecting rod 214, and a second connecting rod 215. The slide rod 212 is slidably disposed on the top wall of the receiving cavity 400 along a first direction, or it can be equipped with a separate slide rail. The hinge portion of the door 100 and the body 600 has two ends. The slide rod 212 can slide back and forth between the first end and the second end of the hinge portion, thus realizing the relative movement of the slide rod on the slide rail.

[0050] The aforementioned transmission rods 211 include: rigid transmission rods, flexible transmission rods, hydraulic and starting rods, electric actuators, etc. Among them, rigid transmission rods are made of metal or composite materials, are inflexible, have high transmission efficiency, and require strict installation, but have poor vibration absorption capacity; flexible transmission rods can adopt steel wire rope or carbon fiber braided structures, are more adaptable to complex spatial layouts, have strong impact resistance, and are suitable for dynamic environments, but their transmission efficiency is not as good as that of rigid transmission rods; hydraulic and pneumatic rods are more suitable for scenarios with high thrust and fast response; electric actuators can achieve intelligent and precise control.

[0051] The transmission rod 211 is hinged to the first end of both the door 100 and the slide rod 212. When the door 100 is opened, it drives the transmission rod 211 to move through the hinged connection point. The first connecting rod 214 is hinged to the second end of the slide rod 212, and the second connecting rod 215 is hinged to the slide rail 213. The first connecting rod 214 and the second connecting rod 215 intersect and are hinged together. The position of the slide rail 213 is fixed, fixed to the top wall of the receiving cavity 400. Since one end of the second connecting rod 215 is hinged and fixed to the slide rail 213, and the position of the slide rail 213 is fixed, the position of one end of the second connecting rod 215 is fixed, while the position of the other end is movable. When the sliding rod 212 drives the first connecting rod 214 to move through the hinge point, since one end of the second connecting rod 215 is fixed and the other end is movable, the included angle between the hinge of the first connecting rod 214 and the second connecting rod 215 will decrease, thereby enabling the first connecting rod 214 and the second connecting rod 215 to extend outwards from the opening 500 of the box. This achieves the extension function of the first and second connecting rods.

[0052] The aforementioned slide rails 213 include the following types: roller slide rails, gear slide rails, ball bearing slide rails, damping slide rails, and electric slide rails. Among them, ball bearing slide rails achieve smooth movement through the rolling of ball bearings, have strong load-bearing capacity and support buffering function, and are widely used in mainstream mechanism displays, combining quietness and durability; damping slide rails can reduce impact force to create a comfortable closing effect, ensuring long-term use without maintenance; electric slide rails integrate motor-driven movement and are mostly used in automated control mechanism displays.

[0053] The lighting component 220 is located on one side of the free end of the first link 214 and the second link 215. The lighting component 220 being located on the free end of the fourth link 217 allows for flexible adjustment and efficient installation. This allows for flexible adjustment of the lamp's position: through the elastic arm structure at the free end of the link, the lamp can move freely and hover, requiring only simple operation for adjustment, thus improving ease of use. Furthermore, it simplifies the installation process; the lighting component can be installed simply at the end of the retractable component, reducing installation difficulty and improving efficiency.

[0054] The lighting component 220 can be connected to the linkage by means of bolts or screws, snap-fit ​​connections, pulleys or hook systems, etc.

[0055] In some embodiments, combined with Figures 1-4 The retractable assembly 210 also includes a third link 216 and a fourth link 217. The third link 216 is hinged to the free end of the first link 214, and the fourth link 217 is hinged to the free end of the second link 215. The third link 216 and the fourth link 217 intersect and are hinged.

[0056] The lighting component 220 is connected to one of the third link 216 and the fourth link 217. For example, the lighting component 220 is connected to the third link 216, or the lighting component 220 is connected to the fourth link 217. The third link 216 and the fourth link 217 further extend the display distance of the retractable component.

[0057] The specific working principle of the lighting device in this embodiment is as follows: When the slide bar 212 drives the first connecting rod 214 to move relative to each other through the hinge point, since one end of the second connecting rod 215 is fixed and the other end is movable, the included angle between the hinge of the first connecting rod 214 and the second connecting rod 215 will become smaller. Since the third connecting rod 216 is hinged to the free end of the first connecting rod 214, the fourth connecting rod 217 is hinged to the free end of the second connecting rod 215, and the third connecting rod 216 and the fourth connecting rod 217 intersect and are hinged. Therefore, the angle between the hinge of the first link 214 and the second link 215 becomes smaller, which will cause the angle between the third link 216 and the fourth link 217 to also become smaller. This allows the third link 216 and the fourth link 217 to further extend beyond the box opening 500, based on the extension of the first link 214 and the second link 215 to the outside of the box opening 500. Either the third link 216 or the fourth link 217 can drive the lighting component 220 to extend, thereby expanding the extension distance of the lighting component.

[0058] In some embodiments, combined with Figures 1-4 The fourth link 217 has an extension section that extends beyond the connection point between the third link 216 and the fourth link 217, and the lighting assembly 220 is located in the extension section. When the fourth link 217 is longer than the third link 216, the lighting assembly 220 is located at the free end of the longer fourth link 217, thus enabling the lighting assembly 220 to achieve a greater display distance. Positioning the lighting assembly 220 in the extension section avoids interference with the lighting assembly when the third link 216 and the fourth link 217 move relative to each other; facilitates circuit connection and maintenance, optimizes the installation structure, improves installation efficiency, and makes the installation process more flexible.

[0059] In some embodiments, combined with Figures 1-3 The retractable assembly 210 also includes a slide rail 213. The slide rail 213 is fixed to the top wall of the receiving cavity 400, defining a groove extending along a first direction. A slide rod 212 is disposed in the groove, and the slide rod 212 can reciprocate within the groove of the slide rail 213 along the first direction. This improves space utilization, avoiding the occupation of floor or side space; it also enhances visual integrity, as the slide rail is hidden at the top, reducing exposed components. Furthermore, it reduces hard-to-clean areas and prevents dust accumulation.

[0060] In some embodiments, combined with Figure 1 and Figure 2The enclosure 600 and the door 100 are each provided with a hinge seat 300. The hinge seat includes a first hinge seat 310 and a second hinge seat 320. The first hinge seat 310 is located at one end of the enclosure 600 along a first direction, and the first hinge seat 310 has a first hinge hole extending along a second direction. The door is provided with a second hinge seat 320 connected to the first hinge seat, and the second hinge seat has a second hinge hole extending along a second direction. The enclosure 600 and the door 100 are connected by a hinge shaft 330 passing through the first and second hinge holes. The second direction is vertical. The opening and closing functions of the door are achieved through the hinge seats (first hinge seat 310 and second hinge seat 320), the hinge holes, and the hinge shaft 330.

[0061] The design of the hinge seats 300, hinge holes, and hinge shafts 330 on the aforementioned container body 600 and door 100 is mainly for achieving stable connection of the door and frequent opening and closing functions, meeting the requirements of load-bearing capacity, cold resistance, and impact resistance. The first and second hinge seats can be made of Q354B high-strength steel with a thickness of 8-12mm, and a single hinge can withstand a static load of over 5000N, suitable for container doors weighing 300-500kg. The hinge shaft can be made of round steel core with bronze bushings to ensure smooth rotation in low-temperature environments and stable starting torque. An anti-detachment structure is provided; locking plates can be fixed at both ends of the hinge shaft and welded to the shaft shoulders to prevent the hinge shaft from shifting after long-term use, causing the door to sag or tilt. The hinge structure is fixed using high-strength bolts, combined with loosening nuts and spring washers to prevent loosening due to transportation vibrations. 4-6 sets of hinges are evenly distributed along the height of the door to ensure that the gap when the door is closed is less than 2mm, achieving effective rain and dust protection. In addition, the hinge seats, hinge shafts, bolts and other parts mentioned above need to be surface treated and lubricated to optimize their weather resistance.

[0062] In some embodiments, combined with Figure 3 The lighting assembly 220 includes a lampshade 222 and a light-emitting element 221. The lampshade 222 defines a mounting cavity, within which the light-emitting element 221 can be housed. The cavity and the light-emitting element can be fixed by means of snap-fit, rotation, etc. The lampshade 222 provides rain and sun protection for the light-emitting element 221. A wiring channel is provided inside the connecting rods (first connecting rod, second connecting rod, third connecting rod, and fourth connecting rod). The power cord of the light-emitting element can be located inside the wiring channel of the connecting rods or outside the connecting rods. The power cord of the light-emitting element can be wound around or snapped in place. In this way, the lighting assembly 220 can provide a light source for the housing 600.

[0063] The light-emitting element 221 mainly functions as a light source for illumination. The light sources of the light-emitting element 221 include LED lights, explosion-proof lights, emergency lights, floodlights, etc. Among them, LED lights have low energy consumption, long lifespan, and high luminous efficiency, and are available in different brightness and color temperatures to meet different lighting needs; explosion-proof lights can effectively prevent sparks from the lamp body from causing danger; emergency lights can improve lighting in emergencies such as sudden power outages, ensuring the safe evacuation of personnel or the continuation of necessary operations; floodlights have strong focusing capabilities, which can concentrate light onto a large area, making the light inside the container more uniform.

[0064] The light-emitting element contains a controller and expansion components. The controller can stabilize the current to protect the light-emitting element and also assist in starting the light-emitting element. The expansion components include: adapters and converters, sensors and controllers. The adapters and converters are power interface conversion devices that adapt to different voltage and current requirements. The sensors and controllers can detect the environment or signals and automatically adjust the brightness and turn the light on and off.

[0065] Secondly, this application provides an energy storage container, combined with Figure 1 The container includes: any of the above-mentioned container bodies (600). The energy storage container includes: battery modules, a two-way AC switch, a battery management system, an energy management system, and subsystems such as cooling and fire protection.

[0066] Energy storage containers offer modularity and scalability: capacity can be flexibly adjusted by increasing or decreasing the number of containers to suit different scales of energy storage needs; they are also environmentally adaptable: their sealed structure can withstand calculated temperatures, humidity, and dusty environments, ensuring stable equipment operation; and they enable rapid deployment: compared to traditional energy storage facilities, containerized systems can shorten the installation cycle to a few days, making them particularly suitable for emergency power demand scenarios. In addition, energy storage containers can also be used for peak shaving and valley filling of the power grid, power optimization of ships, and supporting new energy power plants.

[0067] An energy storage device is a device for storing electrical energy or other energy sources, housed within the receiving cavity 400 of the enclosure 600. This energy storage device can be a battery module or a battery pack. A battery module, as mentioned above, refers to an intermediate unit composed of multiple battery cells, used to boost voltage or capacity. Modules form manageable units by connecting battery cells, but cannot be used independently as a final energy storage device. A battery pack, on the other hand, is the highest level of the battery system, composed of multiple modules integrating a thermal management system, a battery management system, and a power system. It can be directly applied to end devices, and its core function is to provide a complete energy storage and output solution.

[0068] Energy storage devices are energy storage systems that integrate electrochemical energy storage units within standardized shipping containers. They feature modular expansion and rapid deployment, and are widely used in grid regulation and new energy storage. Containerized energy storage devices include: battery packs (energy storage units), battery management systems (BMS), energy storage AC converters (PCS), energy management systems (EMS), thermal management systems, fire protection and safety systems, and power distribution and monitoring systems. During the charging phase, when battery usage is low, the energy storage AC converter converts AC to DC, and the battery management system controls battery charging. During the discharging phase, when grid usage is high, the energy storage AC converter inverts the DC power from the battery back to AC, and the energy management system prioritizes releasing battery power according to electricity pricing strategies. This technology, through highly integrated design, achieves end-to-end energy storage, conversion, and regulation, and is suitable for grid-connected, industrial, commercial, and off-grid scenarios.
