Description

Technical Field

[0001] This utility model relates to the field of energy storage battery technology, and in particular, it relates to an energy storage plug box limiting structure. Background Technology

[0002] An energy storage container is a device that stores electrical energy and releases it when needed. It combines energy storage with logistics transportation, allowing electricity to be stored and transmitted in different locations, thus enabling more flexible and efficient use of electrical energy. Energy storage containers offer excellent convenience, reliability, economy, and safety, and are therefore widely used in many fields such as power, communications, and transportation.

[0003] Energy storage containers typically include components such as a shell, battery compartment, battery system, cooling system, and control system. The battery compartment generally consists of pillars and multiple battery clusters fixed to those pillars. With the rapid development of energy storage capabilities, existing technology has led to the development of large battery packs, each exceeding 2 meters in length and weighing approximately 700 kg.

[0004] To achieve the goal of installing multiple energy storage modules on a container rack, a structure is needed for arranging and limiting the modules. For example, Chinese invention patent CN118763331A relates to a battery rack for an energy storage container, the energy storage container itself, and a processing method. The battery rack of the energy storage container includes: a base plate adapted to support the battery pack of the energy storage container; multiple mounting plates arranged at intervals along a lateral edge of the base plate, each mounting plate adapted to be fixed to a column of the energy storage container; and multiple limiting plates, each limiting plate positioned between two adjacent mounting plates and opposite the base plate, forming a limiting cavity between the limiting plate and the base plate to constrain the battery pack. This battery rack has good structural strength and rigidity, can stably constrain the battery pack, can meet the installation needs of large battery packs, and has strong adaptability.

[0005] However, the battery cluster structure of the above-mentioned energy storage container still has the following drawbacks: After the energy storage plug is installed, there is still a distance between the upper and lower limiters and the side beams of the energy storage plug, and its limiting effect is not good. Longer energy storage plugs require more upper and lower limiters. Longer energy storage plugs have poor upper and lower rigidity during actual transportation. If they pass through bumpy roads or other complex road conditions, they are more likely to jump up and down, and are prone to collision with the upper and lower limiters, resulting in damage to the energy storage plug.

[0006] Therefore, in order to solve the above problems, it is necessary for us to design a reasonable and efficient energy storage box limiting structure. Utility Model Content

[0007] The purpose of this utility model is to provide a limiting structure for energy storage boxes. By setting a movable limiting plate between the fixed limiting plate and the side beam of the box, and connecting the movable limiting plate to the fixed limiting plate through mounting columns and elastic plates, the limiting structure can be directly connected to the side beam of the box. This can provide a good limiting effect for energy storage boxes of various specifications, and ensure the stable flexible limiting of the energy storage box during transportation. The energy storage box is installed stably and reliably and is not easily damaged.

[0008] To achieve the above objectives, this utility model employs the following technical solution:

[0009] An energy storage box limiting structure includes a fixed limiting plate disposed on a side plate of a cluster frame and a movable limiting plate disposed on the fixed limiting plate. The movable limiting plate is located below the fixed limiting plate. An upwardly extending mounting post is provided on the movable limiting plate. A through hole is provided on the fixed limiting plate to facilitate the passage of the mounting post. A pin is provided on the mounting post. An elastic element extending towards the fixed limiting plate is provided on the movable limiting plate. This structure ensures that when the energy storage box is placed on the bottom plate of the cluster frame, the side plate of the cluster frame is located on the side of the energy storage box, and the lower side of the movable limiting plate contacts the upper side of the side beam of the energy storage box, thus limiting the energy storage box.

[0010] As a preferred embodiment of this invention, the number of mounting posts and perforations is at least two.

[0011] As a preferred embodiment of this utility model, the fixed limiting plate includes a first plate and a first wing plate disposed at the end of the first plate, and the movable limiting plate includes a second plate and a second wing plate disposed at the end of the second plate; the through hole is disposed on the first wing plate, and the mounting post is disposed on the second wing plate.

[0012] As a preferred embodiment of this utility model, the first plate and the second plate are arranged in parallel, and there are two of each of the first wing plate and the second wing plate.

[0013] As a preferred embodiment of the present invention, the height of the end of the second wing plate away from the second plate is higher than the height of the end of the second wing plate close to the second plate; the height of the end of the first wing plate away from the first plate is higher than the height of the end of the first wing plate close to the first plate.

[0014] As a preferred embodiment of this invention, a guide limiting groove is provided on the side of the second plate away from the first plate.

[0015] As a preferred embodiment of this invention, the number of guide limiting grooves is at least one.

[0016] As a preferred embodiment of this invention, at least a portion of the guide limiting groove is arc-shaped.

[0017] As a preferred embodiment of this utility model, the elastic element is an elastic sheet; in fact, there are two elastic sheets, and the distance between the two elastic sheets decreases as the distance from the second plate increases. Preferably, the ends of the two elastic sheets furthest from the second plate are arranged parallel to the first plate.

[0018] As a preferred embodiment of this invention, the mounting post is provided with a pin hole for facilitating the insertion of the pin.

[0019] As a preferred embodiment of this invention, the number of pin holes is at least one.

[0020] As a preferred embodiment of this utility model, both the fixed limiting plate and the movable limiting plate are integrally formed parts.

[0021] The beneficial effects of this energy storage plug box limiting structure are as follows:

[0022] 1. By setting a movable limiting plate between the fixed limiting plate and the side beam of the insertion box, the movable limiting plate is connected to the fixed limiting plate through the mounting column and elastic plate. When the energy storage insertion box is inserted into the container cluster, the movable limiting plate can be directly connected to the side beam of the insertion box, providing a good limiting effect for the energy storage insertion box.

[0023] 2. Since the movable limit plate is connected to the fixed limit plate through the mounting column and elastic plate, movable limit plates of different specifications can be installed to limit the movement of energy storage boxes of various specifications.

[0024] 3. During transportation, when the energy storage module is bumped and displaced, the movable limit plate can also move up and down under the action of the elastic sheet to ensure the stable flexible limit of the energy storage module. The energy storage module is installed stably and reliably and is not easily damaged.

[0025] 4. Since each limiting structure can effectively limit the energy storage box, when installing limiting structures for longer energy storage boxes, the number of limiting structures can be appropriately reduced while still ensuring stable limiting, saving the number of limiting structures and making the installation of energy storage boxes more convenient.

[0032] The following are specific embodiments of the present invention, which further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0033] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement and steps of the modules and steps set forth in these embodiments do not limit the scope of the present invention.

[0034] At the same time, it should be understood that, for ease of description, the process shown in the attached diagram is not performed in isolation, but rather involves multiple steps that overlap.

[0035] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0036] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0037] Techniques, methods, and systems known to a person skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the license specification.

[0038] Example 1: As Figures 1 to 5The diagram shown is merely one embodiment of this utility model. An energy storage box limiting structure includes a fixed limiting plate 1 disposed on a cluster frame side plate 3 and a movable limiting plate 2 disposed on the fixed limiting plate 1. The movable limiting plate 2 is located below the fixed limiting plate 1. An upwardly extending mounting post 21 is provided on the movable limiting plate 2. A through hole 11 is provided on the fixed limiting plate 1 to facilitate the passage of the mounting post 21. A pin 22 is provided on the mounting post 21. An elastic member 23 extending towards the fixed limiting plate 1 is provided on the movable limiting plate 2. This structure ensures that when the energy storage box is placed on the bottom plate of the cluster frame, the cluster frame side plate is located on the side of the energy storage box, and the lower side of the movable limiting plate contacts the upper side of the side beam of the energy storage box, thus limiting the energy storage box.

[0039] In this utility model, the cluster frame side plate 3 is directly set on the bottom plate 4 of the cluster frame, serving as the left and right limiting side plates when the energy storage box 5 is installed. The fixed limiting plate 1 is set on the cluster frame side plate 3 and extends towards the installation position of the energy storage box, so that after the energy storage box is installed, the side beam of the box is located below the fixed limiting plate 1. The movable limiting plate 2 is located below the fixed limiting plate 1, so that the movable limiting plate 2 can directly contact the side beam of the energy storage box 5, thereby effectively limiting the side beam of the box.

[0040] In existing cluster racks, the energy storage boxes are limited by installing a horizontal limiting plate directly on the side plate 3 of the cluster rack, similar to the fixed limiting plate of this utility model. However, the disadvantage of this limiting structure is that it cannot make contact limiting for energy storage boxes of different specifications. That is, there is a distance between the energy storage box and the limiting plate. Firstly, the limiting ability is poor, and secondly, the energy storage box is easily damaged by up-and-down bumps during transportation.

[0041] In this utility model, a through hole 11 is made in the fixed limiting plate 1, and a movable limiting plate 2 with a mounting post 21 is installed on the fixed limiting plate 1, so that the movable limiting plate 2 can be hung on the lower side of the fixed limiting plate 1. When the energy storage box is installed, the lower side of the movable limiting plate 2 can contact the side beam of the box to limit the contact of the energy storage box. Moreover, the movable limiting plate 2 is provided with an elastic element 23 extending towards the fixed limiting plate 1. Under the action of the elastic element 23, it is ensured that even if the energy storage box is bumped during transportation, it can still effectively contact the movable limiting plate 2. The movable limiting plate 2 can stably apply a downward pressure to the energy storage box under the elastic force. The energy storage box has a good limiting effect and is not easily damaged during transportation.

[0042] Specifically, the movable limiting plate 2 is provided with an upwardly extending mounting post 21, and the fixed limiting plate 1 is provided with a through hole 11 for the mounting post 21 to pass through. The mounting post 21 is provided with a pin 22. The movable limiting plate 2 is fixedly connected to the mounting post 21, and the mounting post 21 extends vertically upward. The movable limiting plate 2 is placed below the fixed limiting plate 1, and then the movable limiting plate 2 is raised so that the mounting post 21 passes through the through hole 11 from bottom to top. Then, the pin 22 is inserted into the mounting post 21 above the through hole 11. At this time, the pin 22 will hang the mounting post 21 on the fixed limiting plate 1.

[0043] Of course, the number of mounting posts 21 and through holes 11 is at least two, that is, at least two sets of mounting posts 21 are inserted into one through hole 11 respectively, and after the pins 22 are installed respectively, the effective mounting and installation of the movable limiting plate 2 can be completed.

[0044] Depending on the required specifications of the energy storage boxes to be installed, different specifications of movable limit plates 2 can be hung on the fixed limit plate 1 to ensure that the side beams of the boxes can be effectively limited.

[0045] Of course, the movable limiting plate 2 is provided with an elastic element 23 extending towards the fixed limiting plate 1, so that a flexible buffer contact is formed between the movable limiting plate 2 and the fixed limiting plate 1, that is, the fixed limiting plate 1 is flexibly connected to the side beam of the energy storage box. When the energy storage box is installed, it is ensured that the movable limiting plate 2 effectively abuts against the upper side of the side beam of the energy storage box under the elastic force, and the energy storage box is effectively limited. Moreover, during transportation, when the energy storage box is bumped up and down, there is also an effective buffer, and the energy storage box is not easily damaged.

[0046] Example 2, still as Figures 1 to 5 As shown, this is only one embodiment of the present utility model. Based on the first embodiment, in the energy storage box limiting structure of the present utility model, the fixed limiting plate 1 includes a first plate 12 and a first wing plate 13 disposed at the end of the first plate 12, the movable limiting plate 2 includes a second plate 24 and a second wing plate 25 disposed at the end of the second plate 24; the through hole 11 is disposed on the first wing plate 13, and the mounting post 21 is disposed on the second wing plate 25.

[0047] The height of the end of the second wing plate 25 away from the second plate 24 is higher than the height of the end of the second wing plate 25 near the second plate 24; the height of the end of the first wing plate 13 away from the first plate 12 is higher than the height of the end of the first wing plate 13 near the first plate 12.

[0048] Here, there are two of each of the first wing plate 13 and the second wing plate 25; this is equivalent to both ends of the movable limiting plate 2 being tilted upwards, which makes it easy for the energy storage box to reach the lower side of the second plate 24 during installation, and the second wing plate 25 plays a guiding role; similarly, in order to prevent the second wing plate 25 from hitting the fixed limiting plate 1 and causing a hard collision when the movable limiting plate 2 moves upwards, the two ends of the first plate 12 of the fixed limiting plate 1 are also tilted upwards to form the first wing plate 13.

[0049] Generally, the first plate 12 and the second plate 24 are set in parallel, which means that both the first plate 12 and the second plate 24 are set in parallel with the base plate of the energy storage box.

[0050] Example 3, as Figures 1 to 5 As shown, this is only one embodiment of the present invention. Based on any of the above embodiments, in the energy storage box limiting structure of the present invention, the second plate 24 is provided with a guide limiting groove 26 on the side away from the first plate 12.

[0051] There may be protruding structures on the side beam of the insertion box. The extension direction of this guide limiting groove 26 is the same as the extension direction of the side beam of the insertion box. This is to facilitate the passage of the protrusions on the side beam of the insertion box, and also to limit the lateral displacement of the side beam of the insertion box, preventing the side beam of the insertion box from moving horizontally in the direction perpendicular to the guide limiting groove 26, thus making the installation of the energy storage insertion box more stable.

[0052] Of course, the number of guide limiting grooves 26 is at least one, and the guide limiting grooves 26 are set to fit the structure of the box girder.

[0053] Furthermore, at least a portion of the guide limiting groove 26 is arc-shaped, which can be configured as an arc-shaped groove for more stable contact with the box girder structure.

[0054] Example 4, as Figures 1 to 5 As shown, this is only one embodiment of the present invention. Based on any of the above embodiments, in the energy storage box limiting structure of the present invention, the elastic element 23 can be a spring, a soft pad, or an elastic sheet.

[0055] Taking the elastic element 23 as an example, there are two elastic sheets, and the distance between the two elastic sheets decreases as the distance from the second plate 24 increases. The further away the two elastic sheets are from the second plate, the closer they get to each other. However, the ends of the two elastic sheets away from the second plate do not directly contact each other, i.e., there is a distance. The ends of the two elastic sheets away from the second plate 24 are arranged parallel to the first plate 12, which increases the contact area between the elastic sheet 23 and the first plate 12 and ensures stable and safe elastic contact.

[0056] In this utility model, the mounting post 21 is provided with a pin hole 211 for facilitating the insertion of the pin 22. The pin 22 is horizontally inserted into the pin hole 211 to complete the mounting and installation of the movable limiting plate 2 and the fixed limiting plate 1.

[0057] Of course, the number of pin holes 211 is at least one, and the setting height of multiple pin holes 211 is different. Depending on the installation of different energy storage boxes, the pin 21 can be inserted into the pin holes 211 at different heights to install the movable limiting plate 2.

[0058] Finally, both the fixed limiting plate 1 and the movable limiting plate 2 are integrally molded parts. The fixed limiting plate 1 and the movable limiting plate 2 have stable structures, are not easily damaged, have high safety, and are simple to manufacture and have low cost.

[0059] This utility model discloses a limiting structure for energy storage boxes. By setting a movable limiting plate between a fixed limiting plate and the side beam of the box, and connecting the movable limiting plate to the fixed limiting plate through mounting columns and elastic plates, the limiting structure can be directly connected to the side beam of the box. It can provide a good limiting effect for energy storage boxes of various specifications, and ensures stable flexible limiting of the energy storage box during transportation. The energy storage box is installed stably and reliably and is not easily damaged.

[0060] This utility model is not limited to the specific embodiments described above, and various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made to the above embodiments based on the technical essence of this utility model should be included within the protection scope of this utility model.
