Description

Technical Field

[0001] This application relates to the field of battery technology, and in particular to transfer devices. Background Technology

[0002] Battery modules are the core components of modern energy storage systems, consisting of numerous individual cells integrated and packaged using specific series-parallel connections. This design not only effectively improves the overall voltage platform but also significantly increases usable capacity, serving as the fundamental unit to meet modern high energy density demands. With the widespread application of renewable energy, the proliferation of electric vehicles, and the rapid growth in grid peak-shaving needs, the requirements for battery capacity are increasing. To meet these ever-escalating energy demands, multiple battery modules are typically combined through further series-parallel connections to construct larger energy storage systems.

[0003] As the basic deployment unit of large-scale energy storage facilities, energy storage cabinets typically employ a compact vertical layout, integrating a large number of vertically arranged battery modules within a limited space. However, during the on-site installation of energy storage cabinets, the sheer weight of individual modules makes manual handling impractical and dangerous. Therefore, specialized material handling equipment, such as electric transfer vehicles or forklifts, is essential to safely transport the modules from the storage area to the vicinity of the energy storage cabinet installation location. A common transport method involves stacking multiple modules on transfer vehicles or pallets. However, once the transport equipment arrives at the target energy storage cabinet, operators must unload the stacked modules one by one, then individually carry and install them onto pre-designated vertical racks within the cabinet. This "stacked transport - unloading - installation" process is not only cumbersome but also time-consuming and labor-intensive, impacting the efficiency of on-site energy storage cabinet assembly. Utility Model Content

[0004] Therefore, it is necessary to provide a transfer device that is easy to operate and has high transfer efficiency to address the above-mentioned technical problems.

[0005] A transfer device, the transfer device comprising:

[0006] Frame; and,

[0007] Multiple tray assemblies are used for alignment with module placement positions in the energy storage cabinet. The multiple tray assemblies are arranged side-by-side on the frame. Each tray assembly includes:

[0008] Adjustment bracket, for movably connecting the frame body; and,

[0009] The carrier has at least two members, both ends of which are connected to the adjustment frame. The carrier is used to place the battery module, and the battery module can be transferred from the carrier to the module placement position along a first direction.

[0010] In one embodiment, the carrier includes at least a side carrier rail located at the edge of the adjustment frame, and the side carrier rail is provided with a limiting member for restricting the position of the battery module.

[0011] In one embodiment, the limiting member includes a first limiting member disposed at the opposite end of the side bearing guide rail along the first direction. The first limiting member is rotatable relative to the side bearing guide rail. When the first limiting member rotates to a first position, the battery module is disposed on the side bearing guide rail without restriction. When the first limiting member rotates to a second position, the first limiting member restricts the position of the battery module in the first direction.

[0012] In one embodiment, the first limiting member includes a rotating part and a limiting part protruding from the rotating part. The rotating part is rotatably connected to the side bearing guide rail, and the side bearing guide rail has a bearing surface for receiving the battery module. When the first limiting member rotates to a first position, the limiting part does not exceed the bearing surface. When the first limiting member rotates to a second position, the limiting part protrudes from the bearing surface.

[0013] In one embodiment, the first limiting member further includes a stop portion, which protrudes from one end of the rotating part away from the limiting member. A positioning rod is provided on the side bearing guide rail. The stop portion cooperates with the positioning rod to make the first limiting member stationary in the second position.

[0014] In one embodiment, the limiting member includes a second limiting member, the carrier member has a bearing surface for receiving the battery module, and the second limiting member is disposed on one side of the carrier member along a first direction and protrudes from the bearing surface.

[0015] In one embodiment, the support member further includes an intermediate support guide rail located in the middle of the adjustment frame, the intermediate support guide rail being spaced apart from the side support guide rails.

[0016] In one embodiment, the support member further includes a housing and a plurality of pulleys. The housing has a receiving cavity, and the plurality of pulleys are rotatably disposed within the receiving cavity, forming a support surface for receiving the battery module.

[0017] In one embodiment, the carrier further includes a housing and a connector, the connector being disposed at opposite ends of the housing along a first direction, and the connector being detachably connected to the adjustment frame.

[0018] In one embodiment, one of the adjustment frames of the frame and the tray assembly is provided with an adjustment groove and the other is provided with an adjustment member, the adjustment member being slidably connected to the adjustment groove, so that the position of the tray assembly relative to the frame is adjustable.

[0019] The aforementioned transfer device allows each pallet assembly to hold one battery module. Multiple pallet assemblies are arranged side-by-side on the frame, establishing a one-to-one correspondence between battery modules and pallet assemblies. An adjustable frame is movably connected to the frame, making the overall position of the pallet assembly relative to the frame adjustable. This allows the battery module to be aligned with its placement position on the energy storage cabinet. When assembling the energy storage cabinet, the position of the transfer vehicle is adjusted to align the modules on the frame with their placement positions on the energy storage cabinet, and the modules can be directly pushed in. This convenient operation helps improve the installation efficiency of the energy storage cabinet. Attached Figure Description

[0028] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0029] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application 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, and therefore should not be construed as a limitation of this application.

[0030] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0031] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0032] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0033] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0034] See Figure 1 , 2 , Figure 1 , 2 A schematic diagram of the transfer device 1 according to an embodiment of this application is shown. This embodiment provides a transfer device 1, which includes multiple pallet assemblies 10 and a frame 20. The multiple pallet assemblies 10 are used for alignment with module placement positions in an energy storage cabinet, and the multiple pallet assemblies 10 are arranged side-by-side on the frame 20. (See reference...) Figure 3-6 , Figure 3-6 A schematic diagram of the structure of a tray assembly 10 according to an embodiment of this application is shown. The tray assembly 10 provided in one embodiment of this application includes a support member 100 and an adjusting frame 200. The adjusting frame 200 is movably connected to an external frame 20. At least two support members 100 are provided, with both ends of each support member 100 connected to the adjusting frame 200. The support member 100 is used to place a battery module, and the battery module can be transferred from the support member 100 to the module placement position along a first direction X.

[0035] The aforementioned transfer module's pallet assembly 10 and transfer device 1 each allow one battery module to be placed in each pallet assembly 10. Multiple pallet assemblies 10 are arranged side-by-side on the frame, achieving a one-to-one correspondence between the battery module and the pallet assembly 10. The adjusting frame 200 is movably connected to the frame 20, allowing the overall position of the pallet assembly 10 relative to the frame to be adjustable. This enables the battery module to be aligned with the module placement position on the energy storage cabinet. When assembling the energy storage cabinet, the position of the transfer vehicle is adjusted so that the module on the frame 20 is aligned with the placement position on the energy storage cabinet, and the module can be directly pushed in. This convenient operation helps improve the installation efficiency of the energy storage cabinet.

[0036] Specifically, the battery module moves along the first direction X to the tray assembly 10, and then is transferred along the first direction X to the module placement position. The first direction X is also the longitudinal direction of the carrier 100, and the two ends of the carrier 100 refer to the opposite ends of the carrier 100 along the first direction X. At least two carriers 100 are arranged side by side in the second direction Y (and / or the first direction X), the second direction Y being perpendicular to the first direction X, and the second direction Y being the width direction of the carrier 100. The tray assembly 10 is arranged side by side in the third direction Z (and / or the first direction X and the second direction Y), the third direction Z being a direction perpendicular to the second direction Y and the first direction X respectively, so the adjustment frame 200 can move in the third direction Z.

[0037] In one embodiment, the support member 100 further includes a housing 110 and a plurality of pulleys 120. The housing 110 is provided with a receiving cavity 111, and the plurality of pulleys 120 are rotatably disposed in the receiving cavity 111, forming a support surface for receiving the battery module.

[0038] Specifically, the support member 100 is generally rectangular, and the housing 110 is also rectangular. The number of receiving cavities 111 on the housing 110 corresponds to the number of pulleys 120. The pulleys 120 are rotatably connected to the housing 110 via a pivot (not shown). Each pulley 120 has the same size, and the center line of each pivot is at the same height to keep the support surface horizontal. The pivot is set along the second direction Y, allowing the multiple pulleys 120 to rotate so that the battery module moves along the first direction X to the tray assembly 10.

[0039] In one embodiment, the support member 100 further includes a connector 130, which is disposed at the opposite ends of the housing 110 along the first direction X, and is detachably connected to the adjustment frame 200.

[0040] Specifically, the connecting member 130 is detachably provided at both ends of the housing 110. The connecting member 130 includes a first connecting portion 131 and a second connecting portion 132. The first connecting portion 131 is used for detachably connecting with the housing 110, and the second connecting portion 132 is used for detachably connecting to the adjusting frame 200. The first connecting portion 131 is in a "C" shape or a "匚" shape. The "C" - shaped or "匚" - shaped first connecting portion 131 is first snapped onto the outside of the housing 110, and then is detachably connected to the housing 110 through external parts such as bolts. The second connecting portion 132 is in a "C" shape or a "匚" shape. The "C" shape or "匚" shape of the second connecting portion 132 is opposite to the "C" shape or "匚" shape of the first connecting portion 131. The first connecting portion 131 and the second connecting portion 132 are respectively oriented towards two opposite directions in the third direction Z, so that after one connects the housing 110 and the other connects the adjusting frame 200, the housing 110 and the adjusting frame 200 can be basically at the same horizontal height.

[0041] Further, when the connecting member 130 is provided on the side - bearing guide rail 101, the connecting member 130 is movably connected to the adjusting frame 200, so that the side - bearing guide rail 101 can move relative to the carrier 100. Then the first connecting portion 131 and the adjusting frame 200 are in a slidable snap - connection.

[0042] In one embodiment, the carrier 100 further includes an intermediate - bearing guide rail 102 located in the middle of the adjusting frame 200, and the intermediate - bearing guide rail 102 is spaced apart from the side - bearing guide rail 101.

[0043] Specifically, at least two carriers 100 at least include one side - bearing guide rail 101 and one intermediate - bearing guide rail 102, or at least include two side - bearing guide rails 101. In Figure 3 、 4 In the illustrated embodiment, there are three carriers 100, including two side - bearing guide rails 101 and one intermediate - bearing guide rail 102. The two side - bearing guide rails 101 are used for limiting and matching the size of the battery module, and the intermediate - bearing guide rail 102 is used for supporting the middle part of the battery module. Besides the different installation positions, the intermediate - bearing guide rail 102 may not be provided with the limiting member 300. The connecting member 130 of the intermediate - bearing guide rail 102 can be fixedly arranged relative to the adjusting frame 200. Specifically, the second connecting portion 132 of the intermediate - bearing guide rail 102 is first snapped onto the adjusting frame 200, and then the relative position is fixed to the adjusting frame 200 through external parts such as bolts.

[0044] In one embodiment, one of the adjustment frames 200 of the frame 20 and the tray assembly 10 is provided with an adjustment groove 21 and the other is provided with an adjustment member 230. The adjustment member 230 is slidably connected to the adjustment groove 21, so that the position of the tray assembly 10 relative to the frame 20 is adjustable.

[0045] Specifically, the frame 20 is provided with an adjustment groove 21, and the end of the adjustment frame 200 is provided with an adjustment member 230. The adjustment member 230 includes a sliding block 231 that slides in the adjustment groove 21 and a fixing member 232 that locks the sliding block 231. The position of the tray assembly 10 relative to the frame 20 is adjustable through the sliding block 231. The fixing member 232 is connected to the sliding block 231. By operating the distance between the sliding block 231 and the bottom of the adjustment groove 21, the sliding block 231 can be tightly pressed against the bottom of the adjustment groove 21, thereby locking the sliding block 231 and positioning the tray assembly 10 as a whole in the required position.

[0046] In one embodiment, the adjustment frame 200 includes an adjustment rod 210 and a support rod 220. The adjustment rod 210 is movably connected to the frame body 20, the support rod 220 is connected to all the load-bearing members 100, and the side load-bearing guide rail 101 is movable relative to the support rod 220.

[0047] Specifically, the adjusting rod 210 is a cylindrical rod body, which facilitates a slidable snap-fit ​​connection between the first connecting part 131 and the adjusting rod 210. Multiple support rods 220 are provided, arranged side-by-side at intervals below the bearing member 100, and connected to the housing 110. The support rods 220 are fixedly connected to the intermediate bearing guide rail 102 (by bolts). At least one sliding groove 221 is provided on the support rod 220, corresponding to the movement range of the side bearing guide rail 101. Bolts pass through the sliding groove 221 and connect to the housing 110 of the side bearing guide rail 101.

[0048] In one embodiment, the carrier 100 includes at least a side carrier guide rail 101 located at the edge of the adjusting frame 200, and the side carrier guide rail 101 is provided with a limiting member 300 for restricting the position of the battery module. The limiting member 300 on the carrier 100 can limit the placement of the battery module, thereby restricting the installation path of the battery module, facilitating the alignment of the battery module with the placement position on the energy storage cabinet, and also facilitating the limiting of the battery module during transportation.

[0049] In one embodiment, the limiting member 300 includes a first limiting member 310, which is disposed at the opposite end of the side support guide rail 101 along the first direction X. The first limiting member 310 is rotatable relative to the side support guide rail 101. When the first limiting member 310 rotates to a first position, the battery module is disposed on the side support guide rail 101 without restriction. When the first limiting member 310 rotates to a second position, the first limiting member 310 restricts the position of the battery module in the first direction X.

[0050] Specifically, the first limiting member 310 is disposed within the housing 110 and located at the opposite ends of the side bearing guide rail 101 along the first direction X. At least one first limiting member 310 is provided, located at the end of the side bearing guide rail 101 furthest from the battery module entry end. Figure 4 In the embodiment shown, two first limiting members 310 are provided, located at both ends of the side bearing guide rail 101 respectively.

[0051] Furthermore, the first limiting member 310 includes a rotating part 311 and a limiting part 312 protruding from the rotating part 311. The rotating part 311 is rotatably connected to the side bearing guide rail 101. The side bearing guide rail 101 has a bearing surface for receiving the battery module. When the first limiting member 310 rotates to the first position, the limiting part 312 (the height in the third direction Z) does not exceed the bearing surface. When the first limiting member 310 rotates to the second position, the limiting part 312 protrudes from the bearing surface.

[0052] Specifically, the rotating part 311 is cylindrical or spherical, and the limiting part 312 is conical, triangular, or elongated. The rotating part 311 and the limiting part 312 can be a continuous structure and integrally formed. The first limiting member 310 is also provided in the independent receiving cavity 111 of the housing 110. The first limiting member 310 is spaced apart from the pulley 120, so that in the first position, the limiting part 312 moves to a position facing the pulley 120 and is sufficiently positioned between the rotating part 311 and the pulley 120.

[0053] In one embodiment, the first limiting member 310 further includes a stop portion 313, which protrudes from the end of the rotating part 311 away from the limiting part 312. The side bearing guide rail 101 is provided with a positioning rod 314. The stop portion 313 cooperates with the positioning rod 314 to make the first limiting member 310 stationary in the second position.

[0054] The rotating part 311 has a top surface and a bottom surface. The limiting part 312 protrudes from one side of the top surface, and the stopping part 313 protrudes from the bottom surface. The housing 110 has a through hole, which is arranged side by side with the receiving cavity 111. The first limiting member 310 is disposed in the through hole. When the first limiting member 310 rotates to the first position (or the second position), the stopping part 313 can protrude below the through hole. When the first limiting member 310 rotates from the first position to the second position, the stopping part 313 gradually approaches the positioning rod 314 and abuts against the positioning rod 314 in the second position, thereby achieving limiting and stopping.

[0055] In one embodiment, the limiting member 300 includes a second limiting member 320, the carrier member 100 has a carrier surface for receiving the battery module, and the second limiting member 320 is disposed on one side of the carrier member 100 along a first direction X and protrudes from the carrier surface (along a third direction Z).

[0056] Specifically, the second limiting member 320 is plate-shaped and is located outside the housing 110. It is connected to the housing 110 via a connector 130 sleeved on the outside of the housing 110. Alternatively, the second limiting member 320 is integrally formed with the housing 110, or it is located inside the housing 110. The side bearing guide rail 101 is provided with the second limiting member 320, and the second limiting member 320 is located on the side of the side bearing guide rail 101 away from the other side bearing guide rail 101 or away from the middle bearing guide rail 102.

[0057] In one embodiment, the frame 20 is rectangular, forming the outer frame of the frame, and multiple tray assemblies 10 are disposed within the frame. The frame 20 also has a handle in the middle and wheels at the bottom.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
