Abstract
Description
Technical Field
[0001] This utility model relates to the field of energy storage equipment technology, and in particular to a quick-change structure for a lithium-ion battery energy storage module that is easy to maintain. Background Technology
[0002] Energy storage batteries are devices that store and release electrical energy through chemical or physical means. They are used to balance the supply and demand of the power system and improve energy utilization efficiency. Their working principle is based on the redox reaction of electrode materials. When charging, electrical energy is converted into chemical energy for storage, and when discharging, chemical energy is converted back into electrical energy for output.
[0003] Currently, in large-scale energy storage environments, multiple energy storage battery modules are connected in series or parallel to form energy storage units, creating energy storage battery clusters. These clusters are the key intermediate layer connecting individual batteries and the energy storage system. Their structure typically includes battery modules, busbars, cluster-level management units, and protective housings. Standardized connections enable energy aggregation and unified management. However, current energy storage battery modules in battery clusters often employ an integrated, fixed structure with dense bolts and limited installation space. Disassembly requires specialized tools, making the process cumbersome. Furthermore, the installation and removal of wiring harnesses for energy storage battery modules reduces the efficiency of replacement and maintenance. Utility Model Content
[0004] The purpose of this invention is to provide a quick-change structure for lithium-ion battery storage modules that is easy to maintain, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A quick-change structure for a lithium-ion battery storage module that is easy to maintain includes a main control box. A battery box is fixedly connected to one side of the main control box. The battery box has several battery compartments. A busbar wiring mechanism is provided on the rear side of each battery compartment. Quick-stop mechanisms are respectively provided on both sides of the main control box. Energy storage batteries are interlaced in the battery compartments. Several terminal posts are fixedly connected to the rear side of each energy storage battery. The busbar wiring mechanism also includes a pad. A busbar connecting post is fixedly connected to the pad. The busbar connecting post is connected to the battery box... The busbar is electrically connected, and several elastic copper sheets are fixedly connected to one side of the busbar connecting post. A protective shell is fixedly connected to one side of the pad near the elastic copper sheets. Several pressure-bearing rods are movably connected to the outside of the protective shell. The quick-limiting mechanism also includes two mounting shells, which are fixedly connected to each other. Several locking blocks are interlaced between the two mounting shells. A connecting block is fixedly connected to one side of each of the two locking blocks. A wedge is movably connected to one side of each connecting block. Several fixing rods are fixedly connected to the outside of the pole post.
[0007] As a further preferred embodiment of this utility model, two positioning bosses are fixedly connected to both sides of the battery compartment.
[0008] As a further preferred embodiment of this utility model, positioning grooves are provided on both sides of the energy storage battery, which allows the energy storage battery to be inserted into the battery compartment. The positioning grooves, together with the positioning bosses, enable the positioning and advancement of the energy storage battery, achieving precise docking between the terminal post and the elastic copper sheet. Fixing buckles are fixedly connected to both sides of the energy storage battery near the positioning grooves. After the energy storage battery is inserted into the battery compartment, they can be quickly fixed in place with the help of the locking blocks. Two handles are fixedly connected to the front side of the energy storage battery.
[0009] As a further preferred embodiment of this utility model, the outer side of the protective shell is provided with several recessed grooves, and the inner side of the pressure rod is fixedly connected with several sliders. The sliders are slidably connected in the corresponding recessed grooves. The protective shell located between the sliders and the pad is fitted with a compression spring. Thus, with the help of the compression spring force, the sliders can provide a pushing force to the fixing rod, so that after the locking block releases the limit on the fixing buckle, the energy storage battery is automatically pushed out of the battery compartment a certain distance, making it easy to take the energy storage battery out of the battery compartment.
[0010] As a further preferred embodiment of this utility model, two support plates are fixed at the top inside the mounting shell. These plates can deform after the locking block and connecting block move upward, thereby providing a thrust for the locking block and connecting block to reset. One side of the locking block is inclined, which facilitates the locking block being pressed into the mounting shell by the fixing buckle when the energy storage battery is inserted and connected into the battery compartment. This paves the way for the locking block to be inserted into the through groove in the fixing buckle on one side. The two connecting blocks are respectively provided with inclined grooves on opposite sides.
[0011] As a further preferred embodiment of this utility model, the top of the wedge block fits into the corresponding inclined groove, and one side of the wedge block is also inserted between the inclined groove and the mounting shell to prevent the wedge block from detaching from the mounting shell. A push rod is fixedly connected between the two vertical wedge blocks, which can realize that pushing a single push rod can simultaneously drive the two wedge blocks to push the two connecting blocks to move within the corresponding mounting shell.
[0012] As a further preferred embodiment of this utility model, one end of the pole is tapered, and a slot is provided on the outer side of the pole to provide a basis for the limiting installation of the fixing rod. Several connecting rods are fixedly connected between the two fixing rods. A limiting protrusion is fixedly connected to the inner side of one of the fixing rods. The fixing rod is inserted and connected to the outer side of the pole, and the limiting protrusion is inserted and connected to the slot. Adjacent fixing rods are fixed with screws, so that the combination structure of the fixing rod and the connecting rod can protect the pole. At the same time, when the locking block releases the limiting of the fixing buckle, the pressure rod can push the fixing rod under the force of the compression spring, thereby realizing the ejection action of the energy storage battery in the battery compartment.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] In this invention, the positioning groove and positioning boss work together to allow the energy storage battery to be precisely pushed forward. The busbar wiring mechanism ensures stable connection between the terminal post and the elastic copper sheet, enabling rapid electrical connection between the energy storage battery and the busbar inside the battery box. At the same time, the quick-limiting mechanism enables the energy storage battery to be quickly fixed and unlocked. The locking block and the fixing buckle can be engaged to complete the fixation, and pushing the push rod can release the limit. With the help of the compression spring, the pressure rod is driven to push the energy storage battery out, greatly simplifying the disassembly and assembly process. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] like Figures 1-7 As shown, this utility model provides a quick-change structure for a lithium-ion energy storage battery module that is easy to maintain. It includes a main control box 1, a battery box 2 fixedly connected to one side of the main control box 1, several battery compartments 3 inside the battery box 2, a busbar wiring mechanism 4 located at the rear of each battery compartment 3, quick-stop mechanisms 6 located on both sides of the main control box 1, energy storage batteries 5 inserted into each battery compartment 3, several terminal posts 7 fixedly connected to the rear of each energy storage battery 5, and a pad 8 with a busbar connecting post 9 fixedly connected to it. The busbar connecting post 9 connects to the battery box 2. The busbar is electrically connected, and several elastic copper sheets 20 are fixedly connected to one side of the busbar connecting post 9. A protective shell 10 is fixedly connected to one side of the pad 8 near the elastic copper sheets 20. Several pressure-bearing rods 11 are movably connected to the outside of the protective shell 10. The quick-limiting mechanism 6 also includes two mounting shells 12, and the two mounting shells 12 are fixedly connected to each other. Several locking blocks 13 are interlaced between the two mounting shells 12. A connecting block 14 is fixedly connected to one side of the two locking blocks 13 respectively. A wedge block 15 is movably connected to one side of the connecting block 14. Several fixing rods 25 are fixedly connected to the outside of the pole post 7.
[0025] like Figures 1-2 As shown, two positioning protrusions 16 are fixedly connected to both sides of the battery compartment 3. Positioning slots 17 are provided on both sides of the energy storage battery 5. After the energy storage battery 5 is inserted into the battery compartment 3, the positioning slots 17 and the positioning protrusions 16 realize the positioning and advancement of the energy storage battery 5, and realize the precise docking of the terminal post 7 and the elastic copper sheet 20. Fixing buckles 18 are fixedly connected to both sides of the energy storage battery 5 near the positioning slots 17. After the energy storage battery 5 is inserted into the battery compartment 3, it can be used with the locking block 13 to realize the quick limiting and fixing of the energy storage battery 5. Two handles 19 are fixedly connected to the front side of the energy storage battery 5.
[0026] like Figures 5-7As shown, the outer side of the protective shell 10 has several recesses 21, and the inner side of the pressure rod 11 is fixedly connected to several sliders 22. The sliders 22 are slidably connected in the corresponding recesses 21. The protective shell 10 located between the sliders 22 and the pad 8 is fitted with a compression spring 23. With the help of the force of the compression spring 23, the sliders 22 can provide a pushing force to the fixing rod 25, so that after the locking block 13 releases the limit on the fixing buckle 18, it can automatically push the energy storage battery 5 out of the battery compartment 3 a certain distance, so that the energy storage battery 5 can be taken out of the battery compartment 3. One end of the pole post 7 is conical, and the outer side of the pole post 7 has a slot 24, which is the limit for the fixing rod 25. The mounting provides a foundation, with several connecting rods 26 fixedly connected between the two fixing rods 25. A limiting protrusion 27 is fixedly connected to the inner side of one of the fixing rods 25. The fixing rod 25 is inserted and connected to the outer side of the pole post 7, and the limiting protrusion 27 is inserted and connected to the slot 24. Adjacent fixing rods 25 are fixed with screws, so that the combination structure of fixing rods 25 and connecting rods 26 can protect the pole post 7. At the same time, when the locking block 13 releases the limiting of the fixing buckle 18, the pressure rod 11 can push the fixing rod 25 under the force of the compression spring 23, thereby realizing the ejection action of the energy storage battery 5 in the battery compartment 3.
[0027] like Figures 1-2 , Figure 7 As shown, two support plates 28 are fixed at the top inside the mounting shell 12. They can deform after the locking block 13 and connecting block 14 move upward, thereby providing a thrust for the resetting of the locking block 13 and connecting block 14. One side of the locking block 13 is inclined, which facilitates the insertion of the energy storage battery 5 into the battery compartment 3 by pressing the locking block 13 into the mounting shell 12 through the fixing buckle 18. This paves the way for the locking block 13 to be inserted into the through groove in the fixing buckle 18 later. The two connecting blocks 14 have inclined grooves 29 on opposite sides. The top of the wedge 15 fits into the corresponding inclined groove 29, and one side of the wedge 15 is also inserted between the inclined groove 29 and the mounting shell 12 to prevent the wedge 15 from detaching from the mounting shell 12. A push rod 30 is fixedly connected between the two vertical wedges 15, which can realize that pushing a single push rod 30 will simultaneously drive the two wedges 15 to push the two connecting blocks 14 to move within the corresponding mounting shell 12.
[0028] It should be noted that this utility model is a quick-change structure for a lithium-ion battery storage module that is easy to maintain. When installing the energy storage battery 5, first align the energy storage battery 5 with the opening of the battery compartment 3, so that the positioning grooves 17 on both sides of the energy storage battery 5 are aligned with the positioning protrusions 16 on both sides inside the battery compartment 3. Push the energy storage battery 5 towards the inside of the battery compartment 3 along the direction of the positioning protrusions 16. During the pushing process, the fixing buckles 18 on both sides of the energy storage battery 5 will contact the inclined surface of the locking block 13 in the quick-limiting mechanism 6. Continuous pushing will squeeze the locking block 13 to retract obliquely upward into the mounting shell 12. At the same time, the locking block 13 drives the connecting block 14 to move synchronously. The support piece 28 inside the mounting shell 12 is deformed by compression. When the energy storage battery 5 is pushed to the designated position, the fixing buckle 18 moves below the locking block 13, and the support piece 28 restores its deformation and pushes the connecting block 14. When the connecting block 14 is reset, the connecting block 14 drives the locking block 13 to extend out of the mounting shell 12. The locking block 13 is inserted into the through groove of the fixing buckle 18, completing the limiting and fixing of the energy storage battery 5. Simultaneously, the terminal post 7 on the rear side of the energy storage battery 5 is inserted between several elastic copper sheets 20. The elastic copper sheets 20 are compressed and deformed, tightly wrapping the terminal post 7, realizing the electrical connection between the terminal post 7 and the busbar connecting post 9, thereby allowing the energy storage battery 5 to form a passage with the busbar in the battery box 2, and the energy storage battery 5 can participate in energy storage normally. Two of the fixing rods 25 on the outside of the terminal post 7 push the two pressure rods 11 to move towards the side of the pad 8 at the same time. Thus, the two pressure rods 11 compress the compression spring 23 towards the side of the pad 8, and the combined structure of the two sets of fixing rods 25 and connecting rods 26 is also inserted into the outside of the protective shell 10.
[0029] When it is necessary to replace or maintain the energy storage battery 5, push the corresponding push rod 30 inward with both hands flat. The push rod 30 drives the two vertical wedges 15 to move synchronously. The top of the wedge 15 contacts the inclined groove 29 of the connecting block 14, pushing the connecting block 14 to move upward. The connecting block 14 drives the locking block 13 to disengage from the through groove of the fixing buckle 18, releasing the restriction on the energy storage battery 5. At this time, the compression spring 23 returns to its deformation, pushing the slider 22 to move outward along the sink 21. The slider 22 drives the pressure rod 11 to move synchronously. The pressure rod 11 pushes the fixing rod 25, thereby pushing the energy storage battery 5 outward a certain distance from the battery compartment 3. The staff can easily take it out of the battery compartment 3 through the handle 19 on the front side of the energy storage battery 5 to complete the disassembly operation.
