Description

Technical Field

[0001] This utility model relates to the field of battery module installation, and in particular to a hinged battery module installation structure. Background Technology

[0002] A battery module is an energy storage unit composed of multiple battery cells connected in series and parallel. It typically also integrates auxiliary components such as busbars, insulators, sampling harnesses, and temperature sensors, all encapsulated within a module housing. The module housing is generally made of aluminum alloy, steel plate, or flame-retardant plastic, and has mounting holes or positioning structures on the bottom for fixing it to a battery cabinet, tray, or cooling plate.

[0003] As energy storage systems and electric vehicles increasingly demand higher energy density, the height of battery modules is often limited by cell arrangement and thermal management design, potentially exceeding the standard entry clearance of battery cabinets. Traditional installation methods typically involve vertically pushing or hoisting the module into the cabinet. When the module height exceeds the cabinet entry height, direct installation is not possible. Existing technologies sometimes address this by removing cabinet beams or lowering the module height; however, the former compromises cabinet structural strength, while the latter sacrifices energy density and flexibility in cell selection. Furthermore, for multi-module side-by-side installations, individual installation makes it difficult to ensure precise alignment of module mounting holes with base threaded holes, often requiring repeated adjustments in confined spaces, resulting in low efficiency and increased susceptibility to damage from impacts.

[0004] Currently, some installation structures utilize tilting or flipping methods to load the cabinet, but most rely on hydraulic flaps, electric push rods, or complex linkage mechanisms. These are not only costly and take up extra space, but also difficult to apply in environments without power or in on-site maintenance scenarios. In addition, these structures often use the flipping mechanism as a permanent load-bearing component, which leads to a decrease in positioning accuracy due to wear or deformation after long-term use, and is not easy to replace. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the prior art in dealing with height exceeding the limit and multi-module synchronous installation, such as damage to the cabinet structure, reliance on complex power mechanism, poor positioning accuracy and inconvenient maintenance, and to provide a hinged battery module installation structure.

[0006] The present invention solves the above-mentioned technical problems through the following technical solution:

[0007] This utility model provides a hinged battery module installation structure, including a fixed base, a battery module body and a hinge. The fixed base is connected to the inner wall of the battery cabinet, the fixed end of the hinge is connected to the top of the fixed base, and the rotating end of the hinge is connected to the bottom of the battery module body.

[0008] In this technical solution, the module is tilted into the cabinet and then laid flat by using hinges, without having to modify the cabinet structure or reduce the height of the module. This solves the problem that the battery module cannot be directly installed because its height exceeds the limit of the battery cabinet entrance.

[0009] Moreover, the entire installation process is labor-saving and controllable. Operators can push the module in and close the hinges from outside the cabinet, avoiding the safety risks of multiple people lifting and going deep into the cabinet, and eliminating the need for complex equipment such as hydraulic or electric systems.

A partition unit is slidably arranged between the two sets of fixed frames, and the partition unit is located between the two battery module bodies.

[0015] The dividing unit includes a central frame shell, with both ends of the central frame shell slidably connected to a fixed frame. Abutment components are provided on both the left and right sides of the central frame shell. The central frame shell and the abutment components on both sides are connected by an adjustment component. Both adjustment components are drivenly connected to the control component.

[0016] In this technical solution, two adjacent battery module bodies are separated by a separating unit.

[0017] Preferably, the abutting component includes an abutting plate, and multiple disassembly plates are connected to both the upper and lower sides of the abutting plate.

[0018] In this technical solution, the position of the battery module body is fixed by the abutment plate and the disassembly plate.

[0019] Preferably, both ends of the abutment plate are connected to follower columns, and the end of the follower column away from the abutment plate is connected to an anti-detachment slider, and the outer wall of the anti-detachment slider is slidably connected to the inner wall of the fixed frame.

[0020] In this technical solution, the movement trajectory of structures such as the abutment plate is limited by the follower column and the anti-detachment slider.

[0021] Preferably, the adjusting assembly includes a first rotating connecting strip and a second rotating connecting strip, the center of which is rotatably connected to the surface of the anti-detachment central shaft;

[0022] Both ends of the rotating connecting bar one and the rotating connecting bar two are rotatably connected to movable connecting seats. One of the movable connecting seats is connected to one side of the active sliding plate, and the other movable connecting seat is connected to the side of the driven sliding plate.

[0023] The driven slide plate is slidably connected to the surface of the guide shaft, and both ends of the guide shaft are respectively connected to the inner wall of the abutment plate. The active slide plate is drivenly connected to the control component.

[0024] In this technical solution, the distance between the abutment component and the central frame is adjusted by the distance adjustment component.

[0025] Preferably, the control component includes a control threaded shaft, the two ends of which are rotatably connected through to both sides of the central frame shell;

[0026] The control thread shaft surface is threaded with multiple active slide plates.

[0027] In this technical solution, the distance adjustment component is controlled by a control component.

[0028] Preferably, one end of the control threaded shaft is connected to a first bevel gear, the side of the first bevel gear meshes with a second bevel gear, and the top of the second bevel gear is connected to a rotating disk;

[0029] The central frame shell is connected to both sides of a protective frame, which is located on the outside of the first bevel gear and the second bevel gear.

[0030] The rotating disk is threadedly connected to the locking bolt, and the locking bolt is threadedly connected to the top of the protective frame.

[0031] In this technical solution, the control threaded shaft is rotated by a rotating disk or other structure.

[0032] Preferably, a guide slider is connected to the side of the protective frame away from the central frame shell, and the outer wall of the guide slider is slidably connected to the inner wall of the fixed frame.

[0033] The guide slider and the fixing frame are both threadedly connected to the locking bolts.

[0034] In this technical solution, the position of the central frame is locked by a guide slider and a locking bolt.

[0035] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0036] The positive and progressive effects of this utility model are as follows:

[0037] This utility model uses a hinge to tilt the module into the cabinet and then flatten it, without having to modify the cabinet structure or reduce the height of the module, thus solving the problem that the battery module height exceeds the limit of the battery cabinet entrance and cannot be directly installed.

[0038] Moreover, the entire installation process is labor-saving and controllable. Operators can push the module in and close the hinges from outside the cabinet, avoiding the safety risks of multiple people lifting and going deep into the cabinet, and at the same time, no complex equipment such as hydraulic or electric systems are required.

[0039] At the same time, it ensures the hole alignment accuracy when installing multiple modules simultaneously. The mechanical limit of the hinge ensures that after the hinge is fully closed, the mounting holes on each battery module body automatically align with the threaded holes on the fixed base, without the need for individual adjustments. The structure is simple and the cost is low.

[0040] The final fixing of the battery module body is undertaken by fastening bolts, while the hinges only serve a guiding and positioning function during installation, which facilitates maintenance and ensures long-term operational reliability. Attached Figure Description

[0059] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0060] Figures 1 to 9 The diagram shown is a structural schematic of an embodiment of the hinged battery module mounting structure of this utility model.

[0061] A hinged battery module mounting structure includes a fixed base 1, a battery module body 2, and a hinge 3. The fixed base 1 is connected to the inner wall of the battery cabinet, the fixed end of the hinge 3 is connected to the top of the fixed base 1, and the rotating end of the hinge 3 is connected to the bottom of the battery module body 2.

[0062] The hinge 3 has a built-in torsion spring (a conventional adapter component of the hinge, not shown in a separate drawing but an implicit technical feature within the scope of protection of this application). The elastic force of the torsion spring matches the gravity of the battery module body 2. Its function is to provide a reverse damping force during the closing process of the hinge, to counteract the downward tendency of the module's own gravity, and to prevent the module from accelerating downward due to gravity.

[0063] The module is tilted into the cabinet by using hinges and then laid flat, without the need to modify the cabinet structure or reduce the height of the module. This solves the problem that the battery module cannot be directly installed because its height exceeds the limit of the battery cabinet entrance.

[0064] Moreover, the entire installation process is labor-saving and controllable. Operators can push the module in and close the hinges from outside the cabinet, avoiding the safety risks of multiple people lifting and going deep into the cabinet, and at the same time, no complex equipment such as hydraulic or electric systems are required.

[0065] At the same time, it ensures the hole alignment accuracy when multiple modules are installed synchronously. The mechanical limit of the hinge 3 ensures that after the hinge is fully closed, the mounting holes on each battery module body automatically align with the threaded holes on the fixed base 1, without the need for individual adjustment. It also has a simple structure and low cost.

[0066] The final fixing of the battery module body 2 is undertaken by fastening bolts, while the hinge 3 only serves as a guide and positioning tool during installation, which facilitates maintenance and ensures long-term operational reliability.

[0067] The top of the fixed base 1 is connected to multiple fixed blocks 4, and the top of the fixed blocks 4 is at the same height as the hinge 3 when closed.

[0068] The battery module body 2 is supported by the fixing block 4.

[0069] The top of the fixed base 1 is detachably connected to an auxiliary bracket 5.

[0070] The aforementioned detachable connection methods include bolt connection, quick-connect pin connection, or slot connection.

[0071] The auxiliary bracket serves as a temporary support during the installation of a single battery module.

[0072] During installation, the auxiliary bracket 5 supports the tilted battery module body 2.

[0073] When installing the current battery module body 2, first install the auxiliary bracket 5 onto the top of the fixed base 1.

[0074] With the hinge 3 open and the battery module body 2 tilted, the top surface of the auxiliary bracket 5 contacts the bottom surface of the battery module body 2 to support it, prevent the module from sagging excessively, and facilitate smooth insertion.

[0075] Once the battery module body 2 is laid flat using the traction rope and the hinge 3 is fully closed, the auxiliary support 5 has completed its temporary support function.

[0076] When the operator pulls the traction rope outside the cabinet, they use a "slow and uniform pulling" method, combined with the damping effect of the torsion spring, to achieve a smooth and leveling of the module.

[0077] The traction rope is tied to the upper right side of the battery module body 2 (near the cabinet entrance). The operator holds the traction rope and slowly applies the pulling force, so that the hinge 3 closes slowly under the combined action of the torsion spring damping force and the traction rope pulling force, causing the battery module body 2 to slowly rotate to the upper left and flatten. When the module rotates to a 45° angle with the fixed base 1, the pulling force can be appropriately reduced, and the torsion spring damping force can be used to control the module to continue to rotate smoothly until it is completely horizontal.

[0078] Before installing the next adjacent battery module body 2, remove the auxiliary bracket 5 from the fixed base 1 to make room for the tilting of the next module into the cabinet and avoid obstruction.

[0079] During the pre-installation stage, the fixed end of the hinge 3 is pre-installed and fixed to the top of the fixed base 1, and the rotating end of the hinge 3 is fixed to the battery module body 2 to ensure that the hinge 3 can rotate flexibly. Then, a traction rope is tied above the battery module body 2.

[0080] During the tilting insertion stage, the hinge 3 is kept open, so that the battery module body 2 is tilted relative to the fixed base 1, and the battery module body 2 is placed on top of the auxiliary support 5, thereby reducing the overall height of the battery module body 2. The operator uses tooling to push the tilted battery module body 2 smoothly into the battery cabinet. At this time, the battery module body 2 is still tilted and is not in contact with the fixed base 1.

[0081] During the leveling and tightening stage, the operator pulls the pre-tied traction rope from outside the cabinet, using the traction force to gradually close the hinge 3, causing the battery module body 2 to slowly level. When the hinge 3 is fully closed, the mounting holes on the battery module body 2 automatically align with the threaded holes on the fixed base 1. Finally, a socket wrench is used to pass the fastening bolts through the module mounting holes and lock them into the threaded holes of the base, completing the final fixation of the battery module body 2 and the fixed base 1. At this point, the hinge no longer bears the main load and only serves as a guide and positioning mechanism during the installation process.

[0082] The cabinet entrance is located on the left side of the battery module body 2 and on the right side of the cabinet.

[0083] The traction rope is tied to the upper right side of the battery module body 2, and the main body of the traction rope is led out from the cabinet entrance to the operator outside the cabinet.

[0084] It should be noted that a fixed pulley and a support frame are installed on the outside of the cabinet. When the hinge 3 is closed, the traction rope passes through the fixed pulley and can be pulled directly outside the cabinet, i.e., on the right side of the battery module body 2.

[0085] Initially, the battery module body 2 tilts to the right, with its top tilting downwards and to the right. When the operator pulls the traction rope from outside the cabinet, the traction force acts on the upper right side of the battery module body 2, generating a torque that pulls downwards and to the right while simultaneously causing the module to rotate around the hinge 3. This torque overcomes the module's gravity, causing the hinge 3 to gradually close from the open state, thereby slowly rotating the battery module body 2 to the upper left and leveling it (from a tilted state to a horizontal state). The operator can control the speed and force of pulling the rope to achieve a smooth leveling.

[0086] During the leveling process, operators can also use tools such as insulated push rods to assist in pushing the battery module body 2 into the cabinet entrance to ensure that it is fully inserted into the predetermined position inside the cabinet.

[0087] It is worth noting that although no additional rollers or slide rails are provided on the fixed base 1, the upper surface of the fixed base 1 is a smooth metal or engineering plastic plane, and the bottom of the battery module body 2 (or the bottom surface of the hinge rotating end to which it is fixed) is also a smooth plane.

[0088] In the tilted state, the bottom edge of the battery module body 2 or the edge of the rotating end of the hinge 3 contacts the upper surface of the fixed base 1, forming a sliding fit. The sliding friction between the smooth surfaces is sufficient to achieve smooth pushing under the pushing force of the tooling (such as an insulating push rod).

[0089] Since the module is tilted, most of its weight is shared by the auxiliary support 5 and the operator via the push rod. Only part of the edge contacts the fixed base 1, resulting in less friction. Therefore, the pushing process is effortless and feasible.

[0090] Operators can use a special push rod with a soft roller or slider at one end to press against the side or back of the battery module body 2 at the cabinet entrance and apply a smooth pushing force to make the fixing base 1 and the battery module body 2 slide into the cabinet together, and finally fix the fixing base to the cabinet.

[0091] Throughout the process, the auxiliary support 5 also provides auxiliary support and guidance to the module to prevent it from tipping over.

[0092] As a further simplification of operation, the auxiliary support can also be designed as a foldable structure. Its main body is a telescopic connecting rod, with a support block at the top that fits the bottom surface of the battery module body 2, and the bottom is connected to the fixed base 1 through a quick-release pin; when folded, the height of the auxiliary support can be reduced to below the height of the fixed block 4, and the volume is reduced to 1 / 3 of the original volume, making it easy to remove in a compact space.

[0093] The dismantling steps under the compact layout are as follows: After the current battery module body 2 is laid flat and the fastening bolts are initially locked (not fully tightened, the module can be moved slightly), the operator enters through the battery cabinet entrance and uses a special long-handled pin puller (the length is adapted to the depth of the battery cabinet and can be operated from outside the cabinet) to reach into the battery cabinet and pull out the quick-release pin at the bottom of the auxiliary bracket 5; then, push the auxiliary bracket 5 to fold it, and then use the long-handled tool to remove the folded auxiliary bracket from the gap between the battery module body 2 and the fixed base 1; finally, tighten the fastening bolts to complete the fixation of the current module, and then proceed to install the next module.

[0094] The inner wall of the battery cabinet is connected to two sets of symmetrically distributed fixed frames 6. The fixed frames 6 are connected to the inner wall of the battery cabinet by bolts. A partition unit is slidably arranged between the two sets of fixed frames 6. The partition unit is located between the two battery module bodies 2.

[0095] The dividing unit includes a central frame 7, with both ends of the central frame 7 slidably connected to the fixed frame 6. Abutment components 8 are provided on both the left and right sides of the central frame 7. The central frame 7 and the abutment components 8 on both sides are connected by adjustment components 9. Both adjustment components 9 are drivenly connected to the control component 10.

[0096] By separating two adjacent battery module bodies 2 with a separating unit, not only can battery module bodies 2 at different distances be fixed, but the gap created by the separation also forms a ventilation and heat dissipation channel to facilitate heat dissipation of the battery module bodies 2.

[0097] The partition unit can not only flexibly adapt to and fix battery module bodies 2 with different spacing according to design requirements, ensuring the stability of structural layout and assembly accuracy; at the same time, the reserved gap constructed by the partition unit can naturally form a through ventilation and heat dissipation channel.

[0098] This channel facilitates the smooth flow of air between the battery module bodies 2, thereby promptly removing the heat generated during the operation of the battery module bodies 2, significantly improving heat dissipation efficiency, and ensuring that the battery module bodies 2 operate safely and reliably within a suitable temperature range.

[0099] The abutment component 8 includes an abutment plate 81, and multiple disassembly plates 82 are connected to both the upper and lower sides of the abutment plate 81.

[0100] The battery module body 2 is fixed in position by the abutment plate 81 and the disassembly plate 82.

[0101] The cross-section of the abutment plate 81 is U-shaped.

[0102] Both ends of the abutment plate 81 are connected to follower columns 83. The end of the follower column 83 away from the abutment plate 81 is connected to an anti-detachment slider 84. The outer wall of the anti-detachment slider 84 is slidably connected to the inner wall of the fixed frame 6.

[0103] The movement trajectory of structures such as the abutment plate 81 is limited by the follower column 83 and the anti-detachment slider 84.

[0104] The fixed base 1 and the partition unit are arranged in parallel, and the upper surface of the fixed base 1 and the bottom surface of the abutment plate 81 in the partition unit are on the same horizontal plane. Each partition unit corresponds to two sets of fixed bases 1, which are respectively set on the left and right sides of the partition unit (that is, the fixed bases 1 corresponding to the two battery module bodies 2 are symmetrically distributed on both sides of the partition unit). The length of the fixed base 1 is the same as the length of the battery module body 2. The center frame 7 of the partition unit and the center line of the fixed base 1 are on the same straight line to ensure that the module can accurately correspond to both sides of the partition unit after being aligned.

[0105] After the partition unit is adjusted (the spacing between the two abutment plates 81 is adapted to the width of the battery module body 2), first install the battery module body 2 on the left side of the partition unit: tilt it into the cabinet through the hinge 3, lay it flat, and tighten it initially. Then, the left side of the module is attached to the abutment plate 81 on the right side of the partition unit. The disassembly plate 82 on the abutment plate 81 is aligned with the reserved mounting hole on the module housing. Use bolts to pass through the disassembly plate 82 and the module housing to fix the module to the abutment plate 81.

[0106] The overall installation process is as follows: after one battery module body 2 is placed in the battery cabinet, a partition unit is installed, and then another battery module body 2 is installed, and so on, until all battery module bodies 2 are installed.

[0107] The partition units and battery module bodies 2 are staggered in the battery cabinet, and battery module bodies 2 are provided on both sides of the partition units.

[0108] The adjustable distance assembly 9 includes a first rotating connecting strip 91 and a second rotating connecting strip 92, both of which are rotatably connected to the surface of the anti-detachment central shaft 93 at their center.

[0109] Both ends of the rotating connecting bar 1 91 and the rotating connecting bar 2 92 are rotatably connected to movable connecting seats 94. One movable connecting seat 94 is connected to one side of the active slide plate 95, and the other movable connecting seat 94 is connected to the side of the driven slide plate 96.

[0110] The driven slide plate 96 is slidably connected to the surface of the guide shaft 97, and both ends of the guide shaft 97 are respectively connected to the inner wall of the abutment plate 81. The active slide plate 95 is connected to the control component 10 in a transmission manner.

[0111] The distance between the abutment component 8 and the central frame 7 is adjusted by the distance adjustment component 9.

[0112] The movable connecting seat 94 consists of a fixed shaft and a side plate. Both ends of the fixed shaft are connected to the side plate. The surface of the fixed shaft is rotatably connected to the corresponding rotating connecting strip 91 or rotating connecting strip 92. The side plate is connected to the corresponding active sliding plate 95 or driven sliding plate 96.

[0113] The control assembly 10 includes a control threaded shaft 101, with both ends of the control threaded shaft 101 being rotatably connected to both sides of the central frame 7.

[0114] The control threaded shaft 101 has multiple active slide plates 95 connected to its surface by threads.

[0115] The control component 10 controls the distance adjustment component 9.

[0116] A partition plate 102 is connected to the inner wall of the center frame 7, and the surface of the control thread shaft 101 is rotatably connected to the partition plate 102.

[0117] The control thread shaft 101 is divided into two sections by the partition plate 102, and each section of the control thread shaft 101 has two external threads with opposite thread directions.

[0118] Multiple anti-deviation shafts 103 are connected to the inner wall of the central frame shell 7, and the surface of the anti-deviation shaft 103 is slidably connected to the active slide plate 95.

[0119] When in use, rotating the control threaded shaft 101 will drive the two corresponding active slide plates 95 to move towards or away from each other along the anti-deviation shaft 103. At this time, under the action of the movable connecting seat 94, one end of the rotating connecting bar 1 91 and the rotating connecting bar 2 92 will move closer or further away from each other, so that the rotating connecting bar 1 91 and the rotating connecting bar 2 92 will rotate around the anti-detachment central shaft 93.

[0120] At this time, the other ends of rotating connecting bar 91 and rotating connecting bar 92 move closer or further away from each other, thereby driving the corresponding driven slide plate 96 to move along the guide shaft 97.

[0121] During this process, the guide shaft 97 and the abutment plate 81 can be moved. When the abutment plate 81 moves, it drives the disassembly plate 82 and the follower column 83 to move in the same direction, thereby limiting the movement trajectory of the abutment plate 81 and increasing the stability of the abutment plate 81.

[0122] One end of the control threaded shaft 101 is connected to a first bevel gear 104, the side of the first bevel gear 104 meshes with a second bevel gear 105, and the top of the second bevel gear 105 is connected to a rotating disk 106.

[0123] The central frame 7 is connected to both sides of a protective frame 108, which is located on the outside of the first bevel gear 104 and the second bevel gear 105.

[0124] The rotating disk 106 is threadedly connected to the locking bolt 107, and the locking bolt 107 is threadedly connected to the top of the protective frame 108.

[0125] The control threaded shaft 101 is rotated by a structure such as a rotating disk 106.

[0126] The rotating disk 106 has threaded holes, and the top surface of the protective frame 108 has multiple threaded grooves arranged in a ring array. The locking bolts 107 are threadedly connected to the rotating disk 106 and the protective frame 108 through the threaded holes and threaded grooves, respectively.

[0127] In use, rotating the rotating disk 106 drives the second bevel gear 105 to rotate, which in turn drives the first bevel gear 104 to rotate. When the first bevel gear 104 rotates, it drives the control threaded shaft 101 to rotate.

[0128] After adjustment, the rotating disk 106 and the protective frame 108 are connected by locking bolts 107 to lock the angle of the rotating disk 106.

[0129] A guide slider 11 is connected to the side of the protective frame 108 away from the central frame shell 7. The outer wall of the guide slider 11 is slidably connected to the inner wall of the fixed frame 6.

[0130] The guide slider 11 and the fixed frame 6 are both threadedly connected to the locking bolt 12.

[0131] The position of the central frame 7 is locked by the guide slider 11 and the locking bolt 12.

[0132] The fixed frame 6 has multiple locking screw holes on the side away from the central frame 7, and the guide slider 11 has a movable screw groove. The locking bolt 12 is threadedly connected to the fixed frame 6 and the guide slider 11 through the locking screw holes and the movable screw groove, respectively.

[0133] When in use, the protective frame 108 moves, driving the guide slider 11 to move along the fixed frame 6, and using the guide slider 11 and the fixed frame 6 to support the central frame shell 7 and other structures.

[0134] After adjustment, install the locking bolt 12 and use the locking bolt 12 to connect the fixing frame 6 and the guide slider 11.

[0135] The installation sequence of the partition unit is as follows: First, install the fixing frame 6 on the inner wall of the battery cabinet according to the design requirements;

[0136] Then, the partition unit (central frame 7 and abutment components 8 on both sides) is pre-slidably installed between the two fixed frames 6, and the positions of the abutment plates 81 on both sides are adjusted and locked according to the required battery module spacing by the control component 10 and the adjustment component 9.

[0137] Finally, install the battery module bodies 2 on both sides of the separator unit in sequence.

[0138] As each battery module body 2 is tilted into the cabinet and laid flat via the hinge 3, its side will naturally come into contact with the corresponding abutment plate 81.

[0139] The abutment plate 81 serves to laterally position and limit the module, ensuring that the module is located on the predetermined side of the partition unit after installation.

[0140] The design of the mounting plate 81 facilitates fixed connection with the corresponding structure on the side of the module (such as connecting the module housing by bolts through the mounting plate 82).

[0141] Before disassembly, first unscrew the bolts connecting the module to the abutment plate 81, and then unscrew the fastening bolts connecting the module to the fixed base 1. Subsequently, loosen the locking bolts 107 and locking bolts 12 on the partition unit. By rotating the rotating disk 106, the control threaded shaft 101 is driven to rotate, so that the spacing adjustment component 9 drives the abutment plates 81 on both sides to move towards the central frame 7, increasing the distance between the abutment plates 81 on both sides (the distance can be increased to be greater than the width of the battery module body 2), making room for module transportation.

[0142] For the handling operation, re-tether the traction rope above the battery module body 2, and slowly pull the traction rope to open the hinge 3, causing the module to tilt to the lower right (opposite to the tilt direction during installation); at this time, the operator uses tooling (insulated push rod) to assist in pushing the module, and slowly pulls the tilted module out of the battery cabinet entrance to complete the handling.

[0143] It should be noted that the spacing of the abutment plate 81 of the partition unit can be flexibly adjusted by the spacing adjustment component 9. When transporting, the abutment plate 81 can be retracted to a position close to the central frame 7, which will not obstruct the tilted module. At the same time, the partition unit is slidably connected to the fixed frame 6 through the guide slider 11. If more transport space is required, the locking bolt 12 can be unscrewed and the entire partition unit can be slid along the fixed frame 6 to a position that does not affect the transport of the module, further avoiding obstruction.

[0144] All fasteners (bolts) in this application are located in accessible positions. The hinge 3 only serves as a guide during installation, and the same hinge is used for tilting and disassembly, making the operation simple. The presence of the partition unit does not hinder disassembly; on the contrary, through the limiting effect of its abutment plate, it can prevent adjacent modules from shaking and colliding during disassembly.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
