Description

Technical Field

[0001] This invention relates to the field of energy storage equipment technology, specifically to a modular energy storage integrated machine rapid assembly structure. Background Technology

[0002] Modular energy storage units are highly integrated energy storage systems that standardize and modularize core functional units such as battery energy storage, power conversion, energy management, thermal management, and safety protection, and achieve modular assembly through unified mechanical, electrical, and fluid interfaces.

[0003] The overall assembly process of modular energy storage units can be divided into two key stages: prefabrication assembly in the factory and rapid assembly at the final construction site. The rapid assembly stage mainly adopts the plug-in design of functional modules, with the core being convenience and efficiency.

[0004] However, during the actual assembly process, technicians would carefully place the pre-prepared standardized battery modules and PCS (Power Conversion System) modules into the designated installation positions along the pre-set slots inside the cabinet. After each module was accurately pushed into place, the operator would need to manually tighten the pre-configured bolts to securely fix each functional module to the main cabinet structure. This fixing method is relatively simple and direct, requiring no complex processes. However, in actual operation, due to the need to position multiple modules one by one and tighten multiple bolts sequentially, the steps are relatively repetitive, and the overall operation is still cumbersome. This places high demands on the efficiency and consistency of personnel operations. Therefore, we propose a modular energy storage integrated machine rapid assembly structure. Summary of the Invention

[0005] The purpose of this invention is to provide a modular energy storage integrated machine rapid assembly structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a modular energy storage integrated unit rapid assembly structure, comprising: a cabinet, and a base fixed to the bottom of the cabinet; and further comprising: A support frame is installed inside the cabinet. A power conversion module is fixed on the support frame. The support frame has several through holes, and a support rod is mounted on the support frame via screws. Support plates are fixed to both ends of the support rod by locking devices, which secure the support plates to the top of the support rod. The battery module is mounted on the support plate, which is equipped with a positioning mechanism adapted to the battery module. The positioning mechanism is used to position the battery module on the support plate. The battery module is equipped with an unlocking component, which is used to release the positioning of the battery module.

[0007] Preferably, the locking component includes: a threaded hole on the support rod, the threaded hole being threadedly connected to the screw; a channel communicating with the threaded hole on the support rod; a through groove on the support rod; a rod body slidingly passing through the channel; a movable ring fixed at one end of the rod body abutting against one end of the screw; a return spring a sleeved on the rod body, the two ends of the return spring a being fixed to the movable ring and the channel respectively; two pressing blocks slidably connected inside the through groove; mounting holes on adjacent sides of the two pressing blocks; a return spring b fixed between the two mounting holes; and a transmission column fixed at the end of the rod body away from the movable ring, the transmission column abutting against the pressing blocks.

[0008] Preferably, the top surface of the support rod has at least two limiting grooves, the support plate is fixed with a limiting plate that engages with the limiting grooves, and the support plate is fixed with a baffle that abuts against the battery module.

[0009] Preferably, the positioning mechanism includes: a rotating rod fixed on the support plate, a positioning plate rotatably connected to the rotating rod, a limiting plate fixed on the support plate that abuts against the positioning plate, an mounting rod fixed on the support plate, a spring sheet fixed on the mounting rod and the positioning plate, an mounting plate fixed on the battery module, and a positioning groove adapted to the positioning plate on the mounting plate.

[0010] Preferably, the unlocking component includes: a sliding groove on the mounting plate, a transmission plate slidably connected to the sliding groove, a pull rod slidably passing through the mounting plate and fixed to the transmission plate, a connecting ring fixed on the pull rod, and a return spring c sleeved on the pull rod, with both ends of the return spring c fixed to the connecting ring and the mounting plate respectively.

[0011] Preferably, the support rod has a guide groove that communicates with the through groove, the extrusion block has a guide block that is slidably connected to the guide groove, the two extrusion blocks are arranged on an inclined surface on one side, the other side of the extrusion block has a serrated groove, and the cross-section of the transmission column is arranged in the shape of an inverted trapezoid.

[0012] Preferably, one side of the mounting plate is chamfered, the total width of the battery module and the two mounting plates is the same as the width of the support plate, and the mounting plate and the support plate are slidably connected.

[0013] Preferably, the movable ring is slidably connected to the channel, and the central axes of the movable ring, the rod, and the transmission column are collinear.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This invention employs a locking and fixing method for the support plate, achieving a stable connection through fasteners. This effectively prevents the support plate from loosening or wobbling under load, ensuring the stability and reliability of the entire support system. The invention cleverly completes the locking and fixing operation of the support bracket simultaneously during the assembly of the support rod, making the assembly process simpler and more efficient. No additional fixing steps are required, thus significantly improving the overall efficiency of on-site assembly work.

[0015] This invention, through a positioning mechanism, enables automatic and precise alignment and locking during the process of pushing the battery module into the predetermined position. This effectively solves the problems of cumbersome operation and excessive time consumption inherent in the traditional method of fixing with bolts by manual means. It not only provides great convenience for workers, enabling a single person to easily and smoothly complete the assembly and connection between the battery module and the cabinet, but also significantly improves the work efficiency of the entire battery module assembly process, greatly enhancing the efficiency of assembly work.

[0016] This invention enables unlocking and positioning through manual operation. Pressing the lever releases the fixing constraint on the battery module, allowing the battery module to be easily removed. This greatly simplifies the operation process for staff when performing battery module disassembly tasks, effectively simplifies the operation steps, and significantly improves the efficiency of daily maintenance and replacement of battery modules.

[0017] This invention uses a combination of support rods and support plates to distribute the load-bearing pressure of the battery module, and with equally spaced through holes, the installation height of the support plate inside the support frame can be adjusted according to actual usage needs, thus providing great convenience and flexibility in the assembly process.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1 Please see Figure 1 - Figure 13The modular energy storage unit quick-assembly structure shown in the diagram includes: a cabinet 1, a base 2 fixed to the bottom of the cabinet 1, and a support frame 3 installed inside the cabinet 1. A power conversion module 4 is fixed on the support frame 3. The battery compartment of the cabinet 1 has a double-leaf door on the front and a single-leaf door on the back. The support frame 3 has several through holes 5 evenly spaced. A support rod 7 is installed on the support frame 3 via a screw 6. Support plates 9 are fixed to both ends of the support rod 7 by locking devices 8. At least two limiting grooves 24 are formed on the top surface of the support rod 7. A limiting plate 25 is fixed on the plate 9 and engages with the limiting groove 24. The addition of the limiting groove 24 and the limiting plate 25 creates a pre-positioning effect on the support plate 9. The locking member 8 is used to fix the support plate 9 to the top of the support rod 7. A battery module 10 is provided on the support plate 9. The support plate 9 is provided with a positioning mechanism 11 adapted to the battery module 10. The positioning mechanism 11 is used to position the battery module 10 on the support plate 9. An unlocking member 12 is provided on the battery module 10. The unlocking member 12 is used to release the positioning of the battery module 10.

[0022] In this solution, the locking support plate 9 and the automatic positioning of the battery module 10 are used to change the traditional method of fixing the module with bolts, thereby improving the efficiency of on-site assembly. At the same time, by using the combination of positioning and unlocking, the staff can quickly disassemble and install the module on-site during later maintenance and disassembly, making the disassembly and installation operation more convenient.

[0023] It should be noted that several battery modules 10 are installed in a vertically equidistant arrangement. Each battery module 10 has male and female integrated connectors on its top and bottom surfaces. The power conversion module 4 is located at the bottom of the stack. The connection method is mainly based on prefabricated high-voltage cables and industrial-grade high-current quick-connect connectors. The megawatt-level high-current circuit is connected with hard copper busbar bolts to realize the connection control between the battery module 10 and the power conversion module 4. This is a conventional setting in this field, so it will not be described in detail here.

[0024] In this technical solution, the locking component 8 includes: a threaded hole 13 on a support rod 7, the threaded hole 13 being threadedly connected to a screw rod 6; a channel 15 on the support rod 7 communicating with the threaded hole 13; a through groove 16 on the support rod 7; a rod body 17 slidingly passing through the channel 15; a movable ring 18 fixed at one end of the rod body 17 abutting against one end of the screw rod 6; a return spring a19 sleeved on the rod body 17; the two ends of the return spring a19 being fixed to the movable ring 18 and the channel 15 respectively; and two pressing blocks 20 slidingly connected inside the through groove 16. Mounting holes 21 are provided on both adjacent sides of the 20. A return spring b22 is fixed between the two mounting holes 21. A transmission column 23 is fixed at the end of the rod 17 away from the movable ring 18. The transmission column 23 abuts against the pressing block 20. A baffle 26 that abuts against the battery module 10 is fixed on the support plate 9. When the back of the battery module 10 contacts the baffle 26, the battery module 10 is automatically positioned. The movable ring 18 is slidably connected to the channel 15. The central axes of the movable ring 18, the rod 17 and the transmission column 23 are collinear.

[0025] The support rod 7 has a guide groove 39 that communicates with the through groove 16. The extrusion block 20 has a guide block 40 that is slidably connected to the guide groove 39. The addition of the guide block 40 and the guide groove 39 serves to guide the extrusion block 20. When the extrusion block 20 is subjected to force and moves, it moves smoothly within the opening trajectory of the guide groove 39. The two extrusion blocks 20 are arranged with an inclined surface on one side and a serrated groove 14 is opened on the other side of the extrusion block 20. The cross-section of the transmission column 23 is arranged in the shape of an inverted trapezoid. The extrusion block 20 is made of a soft material, which can further enhance the tightness of the connection with the support bracket when the extrusion block 20 is pressed.

[0026] It should be noted that the diameter of the through holes 5 on the support frame 3 is larger than the outer diameter of the screw 6 to ensure sufficient operating clearance. The main purpose is to allow the operator to easily and smoothly pass the screw 6 through the through holes 5 and then accurately align and screw it into the corresponding threaded hole 13 fixed on the support rod 7. In the entire connection structure, the support rod 7 and the support frame 3 are not connected in a flexible or movable way, but are fastened by the screw 6 as described above, which achieves a stable and rigid connection that cannot be moved relative to each other, thereby ensuring the rigidity, stability and load-bearing capacity of the overall structure and the battery module 10.

[0027] In this solution, the working principle of using locking component 8 to lock the support plate 9 during on-site assembly is as follows: First, the operator needs to accurately place the support rod 7 at the corresponding through hole 5 installation position inside the support frame 3. Then, take the screw 6 and pass it through the through hole 5 on the support frame 3 to make a preliminary connection with the pre-set threaded hole 13 on the support rod 7. In this step, the screw 6 only needs to be screwed in a few turns, without being fully tightened. The main purpose is to use the preliminary engagement between the screw 6 and the threaded hole 13 to achieve the pre-positioning of the support rod 7 and ensure that its position is basically fixed. Afterwards, the operator takes the support bracket and places it steadily on the support rod 7 that has been initially positioned. When placing it, it is necessary to ensure that the limiting plate 25 on the bracket is aligned with the corresponding limiting groove 24 on the support rod 7 or the bearing frame 3 to ensure that the two fit together in place, thereby achieving the initial positioning of the support bracket and providing a foundation for its subsequent stable locking. Finally, the operator uses a wrench to tighten the previously preliminarily connected screw 6. As the tool applies torque, the screw 6 rotates under the action of the threaded transmission, continuously moving deeper into the through hole 5. The deeper movement of the screw 6 contacts the movable ring 18 and generates a squeezing transmission effect. The return spring a19 begins to bear pressure and is in a gradually compressed state. This squeezing transmission drives the rod 17 to be subjected to force, causing the rod 17 to move into the through groove 16. The movement of the rod 17 interacts with the two symmetrically arranged squeezing blocks 20 through the transmission column 23 at its end, forming a squeezing transmission. The transmission effect forces the two squeezing blocks 20 to be subjected to force simultaneously and move stably towards the two sides of the support bracket until they are tightly fitted with the side structure of the support bracket, applying a continuous lateral clamping force. Finally, a firm and reliable locking effect is achieved on the support bracket, thus preparing for the subsequent installation of the battery module 10.

[0028] In this technical solution, the positioning mechanism 11 includes: a rotating rod 27 fixed on the support plate 9, a positioning plate 28 rotatably connected to the rotating rod 27, a limiting plate 29 fixed on the support plate 9 that abuts against the positioning plate 28, an mounting rod 30 fixed on the support plate 9, a spring sheet 31 fixed on the mounting rod 30 and the positioning plate 28, and a mounting plate 32 fixed on the battery module 10. The mounting plate 32 has a positioning groove 33 adapted to the positioning plate 28. One side of the mounting plate 32 is chamfered. The chamfered surface of the mounting plate 32 ensures relatively smooth compression and transmission with the positioning plate 28. The total width of the battery module 10 and the two mounting plates 32 is the same as the width of the support plate 9, and the mounting plate 32 is slidably connected to the support plate 9. Through the width settings of the mounting plate 32 and the battery module 10, the battery module 10 achieves a preliminary positioning effect when pushed into the support plate 9.

[0029] It should be noted that by smoothly and slowly pushing the battery module 10 into the support bracket, the inclined slope structure designed on the mounting plate 32 generates a continuous and stable squeezing action with the positioning plate 28 on the bracket. The ingenious design achieves the precise positioning of the battery module 10 naturally and automatically during the same process of pushing the battery module 10 in. This optimization greatly and significantly improves the work efficiency of positioning and assembling the battery module 10 during on-site assembly.

[0030] The workflow for positioning the battery module 10 using the positioning mechanism 11 is as follows: Personnel smoothly push the battery module 10 into the support plate 9. When the module comes into contact with the mounting plate 32, the chamfered surface at the front end of the mounting plate 32 interacts with the positioning plate 28, generating a certain amount of pressure. Under the transmission of force, the positioning plate 28 is compressed and will rotate around the axis of the rotating rod 27. At the same time, the elasticity of the spring plate 31 ensures that the positioning plate 28 and the limiting plate 29 are in a close fit. When the positioning plate 28 rotates to fully match the preset positioning groove 33, the two will form a stable locking state. At this time, the locking action will be accompanied by a clear sound. This sound signal can promptly remind the on-site operators that the battery module 10 has been successfully positioned, thereby ensuring that the entire installation process is accurate and efficient.

[0031] Example 2: This embodiment supplements Embodiment 1, specifically, as follows: Figure 8 and Figure 9 As shown, the unlocking component 12 includes: a sliding groove 34 on the mounting plate 32, a transmission plate 35 slidably connected to the sliding groove 34, a pull rod 36 slidably passing through the mounting plate 32 and fixed to the transmission plate 35, the pull rod 36 being located on one side of the battery module 10, a connecting ring 37 fixed on the pull rod 36, and a return spring c38 sleeved on the pull rod 36, with both ends of the return spring c38 fixed to the connecting ring 37 and the mounting plate 32 respectively. Utilizing the elastic effect of the return spring c38, the transmission plate 35 is not in contact with the positioning plate 28 when it is not under force.

[0032] Specifically, personnel press the lever 36 to apply force, causing the transmission plate 35 to move under force, making it move smoothly along the track of the slide groove 34. Through the effective compression transmission mechanism formed between the transmission plate 35 and the positioning plate 28, the force is transmitted to the positioning plate 28, causing the positioning plate 28 to flip after being subjected to force. As the positioning plate 28 flips, the original tight fit with the positioning groove 33 is broken, resulting in the complete separation of the connection between the positioning plate 28 and the positioning groove 33. This successfully releases the fixed positioning state of the battery module 10, allowing personnel to smoothly pull the battery module 10 out of the equipment and complete the disassembly process.
