Description

Technical Field

[0001] This utility model relates to the field of container technology, specifically to anti-detachment structures, door panels, and energy storage containers. Background Technology

[0002] With the development of new energy technologies and the continuous growth of energy storage demand, containerized energy storage systems are gradually being widely used in scenarios such as power peak shaving, emergency backup power, and new energy support due to their advantages such as high integration, flexible deployment, convenient transportation, and short construction period. These systems typically integrate multiple functional modules, such as energy storage battery modules and energy storage converter systems, within a standard container, achieving a high degree of integration and modularity in energy storage equipment.

[0003] Currently, some containerized energy storage systems use a flat-door structure, where hinges are installed on the container door panels for rotational connection. When the battery experiences thermal runaway and releases a large amount of gas, the internal pressure rises sharply, potentially breaking the hinges. Under the pressure, the door panel may then "fly" out of the container, posing a significant safety hazard. Utility Model Content

[0004] The embodiments of this utility model provide an anti-detachment structure, door panel, and energy storage container, which helps to prevent the door panel from detaching from the container body when the internal pressure increases, thereby improving the safety and reliability of the structure.

[0005] In a first aspect, embodiments of this utility model provide an anti-detachment structure, comprising: First component; and The second component is rotatably connected to the first component to switch between the first state and the second state; wherein: The second component is provided with a first limiting groove. When the second component is in a first state, at least a portion of the first component is within the first limiting groove; when the second component is in a second state, the first component is outside the first limiting groove; and / or, The first component is provided with a second limiting groove. When the second component is in the first state, at least a part of the second component is inside the second limiting groove; when the second component is in the second state, the second component is outside the second limiting groove.

[0006] By adopting the above technical solution, when the second component is in the first state, at least a portion of the first component can be located in the first limiting groove, and / or at least a portion of the second component can be located in the second limiting groove. Thus, when the door panel connected to the second component is damaged due to a large impact force, and the second component is disengaged under the impact force, the first limiting groove and / or the second limiting groove can limit or block the second component, which helps to prevent the second component and the door panel connected to it from flying outward, thereby improving the safety performance of the structure.

[0007] In one embodiment, the second component includes a first anti-detachment member and a first connecting portion, the first anti-detachment member and the first connecting portion together forming the first limiting groove.

[0008] By adopting the above technical solution, the first anti-detachment component and the first connecting part are used to form a first limiting groove. The first anti-detachment component with different structural forms or materials can provide different limiting strengths, so that the load-bearing capacity of the door panel connected to the second component is adjustable when it is subjected to impact. This is beneficial to setting the maximum impact force that the door panel can withstand according to actual use needs, and improving the applicability and reliability of the anti-detachment structure.

[0009] In one embodiment, the first anti-detachment component is located on the rear side of the first connecting portion in a first direction, and when the second component is in a second state, the first component in the first limiting groove and the first anti-detachment component are spaced apart.

[0010] By adopting the above technical solution, when the door panel connected to the second component is subjected to a large impact force, there is a tendency for it to detach along the first direction. By setting the first anti-detachment component on the rear side of the first connecting part in the first direction, when the door panel tends to detach, the first anti-detachment component can abut against the first component located in the first limiting groove, thereby limiting the second component and the door panel in the first direction, which helps to restrict the detachment of the door panel and improve the safety of the overall structure.

[0011] In one embodiment, the first anti-detachment component includes a first segment and a second segment connected to each other. The first segment extends along a second direction, and the second segment extends along a third direction. The second direction intersects with the third direction. The first segment of the first anti-detachment component and the first connecting portion together form the first limiting groove.

[0012] By adopting the above technical solution, a first anti-detachment component with a specific structural form can be formed by extending the first segment along the second direction and the second segment along a third direction intersecting the second direction. The first anti-detachment component and the first connecting portion together form a first limiting groove, which facilitates the first component entering the first limiting groove when the second component switches to the first state and exiting the first limiting groove when switching to the second state. This not only achieves convenient limiting and release of the first component but also helps to effectively limit the first component located within the first limiting groove when the second component is in the second state and subjected to external impact, thereby restricting the first component and its connected door panel from detaching along the first direction and improving the safety and reliability of the structure.

[0013] In one embodiment, the first anti-detachment component further includes a third segment, which is connected to the second segment and extends along the second direction; The second component also includes a component body, and the third segment is connected to the component body.

[0014] By adopting the above technical solution, the first anti-detachment component is connected to the component body through the third section, which helps to securely set the first anti-detachment component on the second component. Thus, when the second component and the door panel connected to it tend to detach along the first direction, the first anti-detachment component can provide more reliable support and limiting function in the structure, which helps to improve the anti-detachment structure's ability to restrict the second component and the door panel, and further enhances the safety performance of the overall device.

[0015] In one embodiment, the first component and the second component rotate about a rotation axis. The first component includes a limiting portion, and the distance of the limiting portion relative to the rotation axis is greater than or equal to the distance of the second component relative to the rotation axis.

[0016] By adopting the above technical solution, the limiting part can cooperate with the second section during the process of the door panel flying out in the first direction, thereby structurally guiding the second component and the door panel connected to it, which helps to limit the door panel from detaching and improves the anti-detachment performance of the device.

[0017] In one embodiment, the projection of the first segment and the first component in the first direction at least partially overlaps, and the length of the overlapping area accounts for 70% to 100% of the total projection length of the first segment in the first direction.

[0018] By adopting the above technical solution, the overlapping area of ​​the projection of the first segment and the first component in the first direction can effectively limit the second component when the second component and the door panel connected to it tend to detach along the first direction. The existence of this overlapping area is the basis for realizing the limiting function. Therefore, by limiting the proportion of this overlapping length, it is beneficial to ensure that the anti-detachment structure has reliable limiting performance.

[0019] In one embodiment, the first component is provided with a protrusion, and when the second component is in a first state, at least a portion of the first component and the protrusion are located within the first limiting groove.

[0020] By adopting the above technical solution and setting the protrusion, during the process of the door panel flying out in the first direction, the first anti-detachment component can first contact the protrusion, and after the first anti-detachment component deforms, it further contacts the first component, thereby forming a step-by-step contact relationship with progressive action. This facilitates the segmented buffering of the inertia generated by the door panel flying out, which helps to reduce the risk of the door panel detaching as a whole and further improves the anti-detachment effect.

[0021] In one embodiment, the first anti-detachment component and / or the second anti-detachment component of the first component are made of metal.

[0022] By adopting the above technical solution, the metal material can undergo elastic or plastic deformation when subjected to a large impact force, thereby playing a deformation buffering role in the impact transmission process. This helps to absorb some of the impact energy, slow down the tendency of door panels and other structures to fly off, and further improve the safety of the overall structure.

[0023] In one embodiment, the first component includes a second anti-detachment member and a second connecting portion, the second anti-detachment member and the second connecting portion together forming the second limiting groove.

[0024] By adopting the above technical solution and setting a second limiting groove, the second component can be further limited on the basis of the limiting provided by the first limiting groove, thereby forming a double limiting structure. This is beneficial to improving the overall anti-detachment performance, further reducing the risk of the second component flying out under abnormal working conditions, and enhancing the safety and reliability of the structure.

[0025] Secondly, embodiments of this utility model provide a door panel including the anti-detachment structure described in the above technical solution.

[0026] By adopting the above technical solution, when the door panel is subjected to a large impact force during use, causing the connection at its rotating shaft to fail, the anti-detachment structure can restrict the door panel, which helps to prevent the door panel from flying out in the first direction, thereby improving the safety and reliability of the door panel structure.

[0027] In one embodiment, the component further includes a door panel body, which is connected to the second component.

[0028] By adopting the above technical solution, the connection between the door panel body and the second component can achieve coordinated limiting of the second component and the door panel body. When the door panel is subjected to a large external force, it helps to limit the tendency of the door panel to come off, thereby preventing the door panel from flying off and improving the safety performance of the overall structure.

[0029] Thirdly, embodiments of this utility model provide an energy storage container, including the anti-detachment structure described in the above technical solution, and also including a container body with an opening and a door panel rotatably connected to the container body through the anti-detachment structure for closing the opening of the container body. The door panel is connected to the second component, and the first component is connected to the container body.

[0030] By adopting the above technical solutions, the safety performance of energy storage containers during use can be improved. In the event of abnormalities such as thermal runaway inside the container, the door panels can be prevented from flying off due to internal pressure or impact, thereby enhancing the structural stability and safety of the energy storage container. The anti-detachment structure can limit and constrain the door panels and secondary components when the internal air pressure of the container increases or when an external force impacts, which helps to suppress the detachment or flying off of the door panels and improve the safety and reliability of the energy storage container.

[0031] The beneficial effects of the embodiments of this utility model are as follows: In embodiments of this invention, by providing a first limiting groove and / or a second limiting groove, when the door panel connected to the second component is subjected to a large impact force, causing the rotational connection between the first and second components to break, the first limiting groove and / or the second limiting groove can effectively limit the detached second component. This limiting effect can prevent the second component and its connected door panel from flying out as a whole, which helps to improve the stability of the door panel structure and the safety performance during use.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present utility model and are not intended to limit the present utility model. In the present utility model, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0036] Firstly, referring to Figures 1 to 7 This utility model provides an anti-detachment structure, including a first component 100 and a second component 200, wherein the second component 200 is rotatably connected to the first component 100 to switch between a first state and a second state.

[0037] In one embodiment, reference is made to Figure 1 , Figure 2 The second component 200 is used to connect with the door panel of the energy storage container, and the first component 100 is used to connect with the container body 20 of the energy storage container. With this structural arrangement, after the door panel is connected to the second component 200, it can rotate relative to the container body 20, thereby having opening and closing functions, which facilitates the ventilation, maintenance or other operation needs of the container.

[0038] Reference Figure 1 , Figure 2The first state can be the state when the door panel is in the closed position, at which time the rotation angle between the second component 200 and the first component 100 is small; the second state is the state when the door panel is open, with a relatively large rotation angle. Through this rotating connection structure, the door panel can be smoothly opened or closed during normal use, meeting the opening and closing requirements of the energy storage container's daily operation.

[0039] It should be noted that in extreme situations such as thermal runaway of the energy storage container, significant internal pressure may be generated, impacting the door panel and causing the rotating connection structure to fail. This could lead to the separation of the first component 100 and the second component 200, and even the risk of the entire door panel flying out. Therefore, a limiting structure is incorporated into the aforementioned structure to effectively restrain the second component 200 during the failure and separation process, thereby reducing the possibility of the entire door panel flying out and improving safety performance.

[0040] Reference Figure 4 , Figure 5 The rotational connection between the second component 200 and the first component 100 can be a hinge, a pivot, or other connection structure that allows relative rotation. The type of connection structure can be flexibly selected according to the specific usage environment and installation method. In this embodiment, the anti-detachment structure may further include several limiting parts 120, which are used to limit the range of motion of the second component 200 when the rotational connection fails, thereby providing protection for the door panel.

[0041] In some embodiments, refer to Figure 1 , Figure 4 When the second component 200 is in the first state, the door panel connected to the second component 200 is in the closed state. At this time, the opening area of ​​the box 20 is blocked by the door panel, thereby achieving the sealing of the box 20, which helps to prevent external impurities or foreign objects from entering the interior of the box 20.

[0042] When the second component 200 is in the second state, the door panel rotates relative to the container 20, entering the open state. At this time, the opening area of ​​the container 20 is open, facilitating operations such as inspection, ventilation, or maintenance of the interior of the container 20. By switching between the first and second states, the door panel can flexibly switch between closed and open states, improving the operational convenience and utilization efficiency of the energy storage container.

[0043] In some embodiments, refer to Figure 1 , Figure 4The second component 200 is provided with a first limiting groove 210. When the second component 200 is in the first state, at least a portion of the first component 100 is located within the first limiting groove 210. This structural relationship creates a nested or mating relationship between the first limiting groove 210 and the first component 100, which to a certain extent constrains the second component 200 and enhances the structural stability of the rotating connection when subjected to impact loads. In other words, the structural arrangement of the first component 100 partially embedded in the first limiting groove 210 allows it to provide a certain degree of limiting and anti-detachment function through the abutment relationship between the first limiting groove 210 and the first component 100 in the event of a sudden situation such as impact or internal thermal runaway of the door panel.

[0044] When the second component 200 is in the second state, the first component 100 is outside the first limiting groove 210. At this time, there is no longer a nested cooperation relationship between the two components, which makes it easy for the door panel to open and meet the user's needs for maintenance, ventilation or daily use of the energy storage container.

[0045] It should be noted that, referring to Figure 4 , Figure 5 The first limiting groove 210 can be a recessed structure, a semi-enclosed structure, or other structural forms that facilitate partial entry of the first component 100. Its specific structural form can be flexibly designed according to the overall structure of the anti-detachment structure, and is not limited to a specific construction method.

[0046] In some embodiments, refer to Figure 1 , Figure 7 The first component 100 is provided with a second limiting groove 110. When the second component 200 is in the first state, at least a portion of the second component 200 is inside the second limiting groove 110; when the second component 200 is in the second state, the second component 200 is outside the second limiting groove 110.

[0047] When the second component 200 is in the first state, at least a portion of the second component 200 is located within the second limiting groove 110. This structural fit facilitates the formation of an interlocking relationship between the first component 100 and the second component 200, thereby restricting relative movement of the second component 200 away from the first component 100 during the closed state. For example, when the door panel tends to fly out due to internal pressure or external impact, the second component 200 within the groove can abut or engage with the second limiting groove 110, thereby providing a certain reverse limiting resistance and restricting the displacement path of the second component 200.

[0048] When the second component 200 is in the second state, the second component 200 exits from the second limiting groove 110, thereby releasing the limiting relationship between the two components and facilitating the opening operation of the door panel.

[0049] The second limiting groove 110 is similar in structure and function to the first limiting groove 210. Both are used to limit and buffer the second component 200 when the rotating connection is damaged or the door panel is subjected to a large external force under certain conditions. By setting the second limiting groove 110, the structural stability of the connection part can be improved to a certain extent, the risk of the second component 200 accidentally detaching can be reduced, and the overall protection effect can be enhanced.

[0050] It should be noted that the specific shape of the second limiting groove 110 can be designed in various ways according to the overall structural requirements. For example, it can be an open groove, a partially enclosed structure, or other structural arrangements that facilitate the embedding of the second component 200. Its setting position and size can also be adjusted according to the actual application scenario so as to achieve effective cooperation under different rotation angles and connection methods.

[0051] In some embodiments, refer to Figure 4 , Figure 7 The second limiting groove 110 and the first limiting groove 210 can be set separately or simultaneously to form a double limiting structure. In the event that the connection between the second component 200 and the first component 100 is damaged, even if one set of limiting grooves fails to function effectively, the other set of limiting structures may still provide residual limiting support for the second component 200, thereby improving the overall fault tolerance and safety in actual use.

[0052] When the second component 200 is in the first state, at least a portion of the first component 100 can be located within the first limiting groove 210, and / or at least a portion of the second component 200 can be located within the second limiting groove 110. Through this mating structure, a certain fitting or insertion relationship can be established when the second component 200 is in a preset working position relative to the first component 100, thereby forming an auxiliary limiting effect. When the door panel connected to the second component 200 is subjected to a large impact force, causing damage to the rotating connection structure between the first component 100 and the second component 200, the second component 200 may detach under external force. At this time, the first limiting groove 210 provided on the second component 200 and / or the second limiting groove 110 provided on the first component 100 can contact or interfere with the corresponding components, playing a role in blocking or restricting the movement path of the second component 200. This can, to a certain extent, suppress the second component 200 and the door panel connected to it from flying out, which helps reduce the risk of structural detachment caused by connection breakage, thereby improving the overall structural stability and safety performance during use.

[0053] In one embodiment, reference is made to Figure 3 , Figure 6 The second component 200 includes a first anti-detachment component 220 and a first connecting portion 230, which together form a first limiting groove 210.

[0054] The first anti-detachment component 220 can be constructed using different materials (such as metal, reinforced plastic, etc.) or different structural forms (such as thickness, bending angle, length, etc.). Since the first anti-detachment component 220 may come into contact with the first component 100 and bear the reaction force under external force, its deformation, strength, and stability will directly affect the limiting performance. For example, when the first anti-detachment component 220 is manufactured using a high-strength material, its resistance to deformation is strong, providing higher support force when the door panel is subjected to a large impact; while when a material with a certain degree of elasticity is used, a certain degree of deformation buffering can be achieved, reducing local stress concentration.

[0055] Therefore, by adjusting the structural parameters or material properties of the first anti-detachment component 220, the anti-detachment structure can be made adaptable to different impact environments, thus allowing the connection between the door panel and the second component 200 to exhibit different load-bearing capacities when subjected to external impact. This structural design method facilitates the adaptation of the maximum impact force that the door panel can withstand according to different usage scenarios, improving the versatility and stability of the anti-detachment structure.

[0056] In one embodiment, reference is made to Figure 4 , Figure 5 The first anti-detachment component 220 is located on the rear side of the first connecting portion 230 in the first direction X. When the second component 200 is in the second state, the first component 100 in the first limiting groove 210 is spaced apart from the first anti-detachment component 220. This structure is beneficial when the door panel is subjected to a large impact force, causing it to tend to detach in the first direction X.

[0057] Specifically, since the first anti-detachment component 220 is located behind the first connecting portion 230, when the door panel tends to "fly out," the first component 100, as the fitting structure part within the limiting groove, will first contact and abut against the first anti-detachment component 220. This abutting action can apply a limiting force to the second component 200 and the door panel connected thereto in the first direction X, thereby effectively suppressing the detachment movement of the door panel.

[0058] This design, through the rational arrangement of structural positions, achieves a certain degree of limitation on the tendency of the door panel to detach, which is beneficial to improving the safety performance and stability of the entire anti-detachment structure. At the same time, the interval setting avoids unnecessary obstruction to the opening of the door panel under normal conditions.

[0059] Furthermore, a certain gap is provided between the first component 100 and the first anti-detachment member 220 within the first limiting groove 210. This gap provides a certain buffer space when the hinge breaks due to force on the door panel. This buffer space helps to prevent the first anti-detachment member 220 from contacting the first component 100 when the door panel undergoes initial deformation at the hinge position, thereby reducing the instantaneous impact on the first anti-detachment member 220 and maintaining the structural strength of the first anti-detachment member 220.

[0060] When the door panel detaches or is close to detaching, the first component 100 and the first anti-detachment component 220 only begin to contact and abut against each other. This structural arrangement helps to achieve a more effective limiting effect. By reasonably designing this interval distance, the load-bearing capacity and buffering performance of the first anti-detachment component 220 can be balanced to a certain extent, improving the reliability and safety of the first anti-detachment structure in practical applications.

[0061] It should be understood that the term "rear side" refers to the rear region along the first direction X, for example... Figure 4 In the diagram, the first direction X is from top to bottom, then in... Figure 4 In this context, the first anti-detachment component 220 is located behind the first connecting portion 230, meaning that the first anti-detachment component 220 is located above the first connecting portion 230.

[0062] In one embodiment, reference is made to Figure 5 , Figure 6 The first anti-detachment component 220 includes a first segment 221 and a second segment 222 that are connected to each other. The first segment 221 extends along the second direction Y, and the second segment 222 extends along the third direction. The second direction Y intersects with the third direction. The first segment 221 of the first anti-detachment component 220 and the first connecting part 230 together form a first limiting groove 210.

[0063] By adopting the above technical solution, the first segment 221 extends along the second direction Y, and the second segment 222 extends along a third direction intersecting the second direction Y, so that the first anti-detachment member 220 forms a three-dimensional limiting member with a specific structural shape. The first limiting groove 210 formed by the first anti-detachment member 220 and the first connecting part 230 facilitates the smooth entry of the first component 100 into the first limiting groove 210 when the second component 200 switches to the first state, and facilitates its exit from the first limiting groove 210 when switching to the second state.

[0064] This design not only enables convenient positioning and release of the first component 100, but also allows the first anti-detachment component 220 to effectively limit the first component 100 located in the first limiting groove 210 when the second component 200 is in the second state and is subjected to external force impact, thereby restricting the first component 100 and its connected door panel from detaching along the first direction X, which is beneficial to improving the safety and reliability of the overall structure.

[0065] In one embodiment, the first anti-detachment component 220 further includes a third segment 223, which is connected to the second segment 222 and extends along the second direction Y; the second component 200 further includes a component body 240, to which the third segment 223 is connected. This structural arrangement allows the first anti-detachment component 220 to provide more reliable support and restraint when the second component 200 and its connected door panel tend to detach along the first direction X, thereby enhancing the anti-detachment structure's ability to restrict the second component 200 and the door panel and further improving the overall safety performance of the device.

[0066] For example, refer to Figure 4 As shown, the first direction X is from top to bottom, the second direction Y is from right to left, and the third direction is from top to bottom.

[0067] It is understood that the first segment 221, the second segment 222, and the third segment 223 are integrally formed structures. In some embodiments, the first anti-detachment component 220 is detachably connected to the component body 240 by bolts, or fixed to the component body 240 by welding. This connection method facilitates the stable installation of the anti-detachment component, while also simplifying maintenance and replacement.

[0068] In one embodiment, the first component 100 and the second component 200 rotate about the rotation axis 300. The first component 100 includes a limiting part 120, the distance of which is greater than or equal to the distance of the second segment 222 relative to the rotation axis 300. When the door panel tends to fly out along the first direction X, the limiting part 120 engages with the second segment 222, thereby structurally guiding the second component 200 and the connected door panel, which helps to limit the door panel from detaching and improves the anti-detachment performance of the device.

[0069] This can be understood as follows: "The distance of the limiting portion 120 relative to the rotation axis 300 is greater than or equal to the distance of the second segment 222 relative to the rotation axis 300." The technical meaning of this is that the distance from any part of the limiting portion 120 to the rotation axis 300 is not less than the distance from any part of the second segment 222 to the rotation axis 300. In one embodiment, the projection of the first segment 221 onto the first component 100 in the first direction X at least partially overlaps, and the length of the overlapping area accounts for 70% to 100% of the total projected length of the first segment 221 in the first direction X.

[0070] The aforementioned "projection overlap" refers to the overlapping area between the first segment 221 and the first component 100 after they are projected onto the first direction X. (Refer to...) Figure 4In the overlapping area, the structure of the first component 100 is located below the first segment 221. With this arrangement, when the second component 200 and its connected door panel are in the first state and are pushed by an external force along the first direction X and tend to fly out, the first segment 221 and the first component 100 can make direct contact or structural interference, thereby restricting the door panel from continuing to move along the first direction X.

[0071] Furthermore, by limiting the proportion of the projected overlap length between the first segment 221 and the first component 100, the coverage area of ​​the limiting region can be adjusted, thereby affecting the limiting effect to a certain extent. Specifically, when the projected overlap ratio is high, the effective contact area between the first segment 221 and the first component 100 increases, providing more stable structural support under large impact loads and suppressing the tendency of the second component 200 and the door panel to detach, thus improving the reliability of the anti-detachment structure under extreme working conditions. When the projected overlap ratio is relatively low, although the limiting area is correspondingly reduced, while satisfying the basic limiting function, the structural interference space between the first component 100 and the first segment 221 can be appropriately released, which is conducive to the door panel opening at a larger angle and improving ease of use.

[0072] Therefore, by setting the length ratio of the overlapping area of ​​the first segment 221 and the first component 100 projected in the first direction X to 70% to 100%, it is beneficial to reasonably adjust the coverage of the limiting area in different usage scenarios according to the balance between safety requirements and ease of opening, thereby improving the adaptability and overall performance of the structure.

[0073] In one embodiment, the projection of the first segment 221 onto the first component 100 in the first direction X at least partially overlaps, and the length of the overlapping area accounts for 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 100% of the total projection length of the first segment 221 in the first direction X. This application does not limit this aspect.

[0074] In one embodiment, the projection of the first segment 221 onto the first component 100 in the first direction X is at least partially overlapped, and the length of the overlapping area accounts for 75%-95% of the total projection length of the first segment 221 in the first direction X.

[0075] In one embodiment, reference is made to Figure 4 , Figure 5The first component 100 is provided with a protrusion 130. When the second component 200 is in the first state, at least a portion of the first component 100 and the protrusion 130 are located within the first limiting groove 210. The protrusion 130 is generally a structure that protrudes from the surface of the first component 100 and may be cylindrical, stepped, or other shapes suitable for realizing a stepped buffer function.

[0076] By providing the protrusion 130, when the door panel tends to fly off along the first direction X, the first anti-detachment component 220 can first contact the protrusion 130. Under the action of a certain external force, the anti-detachment component undergoes a certain degree of deformation and then further contacts the body of the first component 100, forming a stepped contact relationship with progressive action. This design is beneficial for segmenting and buffering the inertial force generated by the door panel flying off, reducing the transmission of impact force, and lowering the risk of the entire door panel detaching, thereby improving the safety performance of the anti-detachment structure to a certain extent.

[0077] The aforementioned stepped contact, through the initial contact between the protrusion 130 and the anti-detachment component, and the subsequent contact between the anti-detachment component and the main body of the first component 100, absorbs and disperses impact energy at different stages, which helps to avoid structural damage caused by concentrated impact force. In addition, the size, shape, and material of the protrusion 130 can be appropriately adjusted according to specific application requirements to adapt to different limiting strength and cushioning needs.

[0078] In one embodiment, the first anti-detachment component 220 and / or the second anti-detachment component 140 are made of metal. When subjected to a large impact force, metal materials can undergo a certain degree of elastic or plastic deformation, thereby achieving a deformation buffering effect during impact transmission. This deformation helps absorb some of the impact energy, slowing down the tendency for the door panel and related structures to detach, thus improving the overall structural safety and reliability to a certain extent.

[0079] In one embodiment, reference is made to Figure 7 The first component 100 includes a second anti-detachment member 140 and a second connecting portion 150, which together form a second limiting groove 110. This second limiting groove 110, based on the first limiting groove 210, provides auxiliary limiting for the second component 200, forming a double limiting structure. Through the synergistic effect of the double limiting structure, the constraint effect on the second component 200 is enhanced to a certain extent. Especially under abnormal operating conditions, when the limiting effect of the first limiting groove 210 may be insufficient, the second limiting groove 110 can further restrict the displacement of the second component 200, slowing its tendency to fly off. Therefore, it is beneficial to improve the overall safety and reliability of the anti-detachment structure and reduce the potential risks caused by the detachment of the second component 200.

[0080] Secondly, referring to Figure 1 , Figure 4This utility model provides a door panel including the anti-detachment structure described in the above embodiments. This door panel possesses all the beneficial effects of the aforementioned anti-detachment structure, which will not be elaborated further herein.

[0081] In one embodiment, the system further includes a door panel body 10, which is connected to the second component 200. The door panel body 10 may be the opening door of an energy storage container or a part thereof, and typically has a certain area and mass. Connecting the door panel body 10 to the second component 200 enables a structural linkage between the two; when the second component 200 is subject to a limiting action, the door panel body 10 is also subject to corresponding structural constraints.

[0082] Specifically, the connection between the second component 200 and the door panel body 10 can be achieved through screwing or welding, thus forming a stable connection in structure. When the door panel body 10 is subjected to a large external force during use, especially an impact along the door opening direction or perpendicular to the direction, the impact will be transmitted to the second component 200 through the door panel body 10. If the first limiting groove 210 and / or the second limiting groove 110 in the anti-detachment structure have already provided a limiting effect on the second component 200, then this limiting effect can simultaneously restrict the movement tendency of the door panel body 10, thereby effectively constraining the entire door panel.

[0083] Through the aforementioned structural arrangement, the connection established between the door panel body 10 and the second component 200 can limit the tendency of the door panel body 10 to detach, provided that the second component 200 is under control. This reduces the risk of the door panel flying out entirely due to external forces, and is beneficial to improving the structural stability and operational safety of the device under extreme operating conditions. Simultaneously, this design also facilitates improving the overall structure's anti-detachment performance without affecting the normal opening and closing function of the door panel, enhancing the safety protection capability of the energy storage container in emergencies such as thermal runaway.

[0084] Thirdly, referring to Figure 3 , Figure 4 This utility model provides an energy storage container, including the anti-detachment structure as described in the above embodiments, or including the door panel as described in the above embodiments. This energy storage container has all the beneficial effects of the aforementioned anti-detachment structure or door panel, which will not be elaborated further in this disclosure.

[0085] In one embodiment, the system further includes a container body 20 with an opening and a door panel rotatably connected to the container body 20 via an anti-detachment structure for closing the opening of the container body 20. The door panel is connected to a second component 200, and the first component 100 is connected to the container body 20. The container body 20 can be the main load-bearing structure of the energy storage container, typically used to house energy storage devices such as battery cells and battery modules, and its overall structure has high strength and rigidity. The first component 100 is connected to the container body 20 by welding, bolting, or riveting to form a stable installation foundation.

[0086] This structural design allows the first component 100, as a key supporting member in the anti-detachment structure, to be firmly fixed to the container 20. This ensures that the first limiting groove 210 and / or the second limiting groove 110 provide reliable limiting reaction force when the door panel and the second component 200 tend to detach along the first direction X or other directions. Especially in cases of abnormal operating conditions such as thermal runaway inside the energy storage container, leading to an abnormal increase in internal air pressure or external mechanical impact, the door panel is prone to outward lifting or detachment. In such situations, the stable installation of the first component 100 on the container 20 enhances the stress stability of the entire anti-detachment structure.

[0087] The embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
