Description

Technical Field

[0001] This utility model relates to the field of electrical technology, and in particular to a stacked lithium battery energy storage device. Background Technology

[0002] In the current trend of energy transition, renewable energy sources such as solar and wind power are being used more and more widely. However, these energy sources are intermittent and unstable, making energy storage devices a key component in ensuring a stable energy supply. Stacked lithium-ion battery energy storage devices, with their flexible capacity expansion capabilities, high energy density, and relatively convenient installation and maintenance, have been widely used in various fields such as residential energy storage, industrial and commercial energy storage, and even small-scale grid energy storage.

[0003] In the home energy storage scenario, as residents become more aware of power stability and energy conservation, more and more families are equipping themselves with energy storage devices. Users expect to be able to easily and flexibly increase or decrease the number of battery modules according to their own electricity needs and home space conditions, achieving free expansion of energy storage capacity to meet needs such as charging during off-peak electricity pricing at night, discharging for self-use during peak daytime electricity consumption, or ensuring the normal operation of critical appliances such as refrigerators and lighting during power outages. Stacked lithium battery energy storage devices can store and allocate electricity generated by distributed generation, balancing the supply and demand difference between power generation and consumption, and improving grid stability and power quality.

[0004] In the actual installation process of existing equipment, traditional battery modules are stacked and installed mainly by manual alignment. Since battery modules are usually heavy and large, manual alignment is extremely difficult. During the alignment process, workers need to rely on experience and visual observation to accurately place the upper layer of modules on the lower layer to ensure that all connection parts are accurately aligned. However, this method is prone to deviation. Once the alignment error between modules exceeds a certain range, subsequent connection processes will be difficult to carry out smoothly, thereby reducing the practicality and reliability of the equipment. Utility Model Content

[0005] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a stacked lithium battery energy storage device. This device can solve the problem that when traditional battery modules are stacked and installed, they mainly rely on manual alignment of each module. Since battery modules are usually heavy and large in size, manual alignment is extremely difficult. During the alignment process, workers need to rely on experience and visual observation to accurately place the upper layer module on the lower layer module to ensure that the connection parts are accurately aligned. However, this method is prone to deviation. Once the alignment error between modules exceeds a certain range, it will make it difficult to carry out subsequent connection processes smoothly, thereby reducing the practicality and reliability of the equipment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a stacked lithium battery energy storage device, comprising a support frame, wherein two positioning components are disposed on the support frame;

[0007] The positioning component includes a lithium battery body, a mounting base, and two protrusions. The lithium battery body is fixedly mounted on the upper surface of the mounting base, and the two protrusions are fixedly mounted on both sides of the lower end of the bracket. Two sliding grooves are opened on the lower surface of the mounting base. Push block grooves are opened on the outer walls of the two protrusions. Two push blocks are slidably connected inside the two push block grooves. First limiting block grooves are opened on the outer walls of both sides of the two protrusions. Limiting blocks are slidably connected inside the four first limiting block grooves.

[0008] Among them, T-shaped blocks are fixedly connected to the upper surface of the two protrusions, T-shaped block grooves are opened inside the two slides, second limiting block grooves are opened on the inner walls of both sides of the two slides, reset springs are set inside the two protrusions, and limiting blocks are slidably engaged inside the two protrusions. The two positioning components are used in conjunction and are set at the top and bottom of the bracket.

[0009] Preferably, the mounting base is slidably connected to the outer wall of the corresponding protrusion via two sliding grooves;

[0010] The outer walls of the two T-blocks are slidably connected to the interior of the corresponding T-block grooves.

[0011] Preferably, the ends of the four first limiting block slots near the second limiting block slots all slide into the interior of the groove and are slidably connected to the interior of the corresponding second limiting block slots.

[0012] Preferably, the two ends of the two return springs are fixedly connected to one side of the outer wall of the corresponding push block;

[0013] The interiors of the four first limiting block slots are respectively connected to the interiors of the corresponding protrusions.

[0014] Preferably, the ends of the four push blocks near the limiting block all slide into the interior of the first limiting block groove and are fixedly connected to the outer wall of the corresponding limiting block, respectively.

[0015] Preferably, the outer walls at both ends of the two limiting blocks are in contact with the outer wall on one side of the corresponding push block.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This stacked lithium battery energy storage device achieves efficient and precise alignment of the lithium battery body through the precise guiding and limiting structure in the positioning component. During installation, simply align the sliding groove on the lower surface of the mounting base with the protrusion at the lower end of the bracket. Utilizing the sliding cooperation between the T-block and the T-slot, the mounting base can be quickly guided to slide in the correct direction.

[0028] Please see Figure 1-4 This utility model provides a technical solution: a stacked lithium battery energy storage device, including a support frame 1;

[0029] Two positioning components are installed on bracket 1;

[0030] The positioning assembly includes a lithium battery body 2, a mounting base 3, and two protrusions 7. The lithium battery body 2 is fixedly mounted on the upper surface of the mounting base 3, and the two protrusions 7 are fixedly mounted on both sides of the lower end of the bracket 1. Two sliding grooves 9 are formed on the lower surface of the mounting base 3. Push block grooves 4 are formed on the outer walls of the two protrusions 7, and two push blocks 5 are slidably connected inside the two push block grooves 4. The mounting base 3 is slidably connected to the outer walls of the corresponding protrusions 7 through the two sliding grooves 9. First limiting block grooves 12 are formed on both sides of the outer walls of the two protrusions 7, and limiting blocks 11 are slidably connected inside the four first limiting block grooves 12. T-shaped blocks 10 are fixedly connected to the upper surface of the two protrusions 7, and T-shaped block grooves 8 are formed inside the two sliding grooves 9. The outer walls of the two T-shaped blocks 10 are slidably connected to the interior of the corresponding T-shaped block grooves 8. The inner walls of the two sliding grooves 9 are slidably connected to the interior of the corresponding T-shaped block grooves 8. Each of the four first limiting block slots 12 is provided with a second limiting block groove 13. The ends of the four first limiting block slots 12 near the second limiting block groove 13 are slidably extended into the interior of the slide groove 9 and are respectively slidably connected to the interior of the corresponding second limiting block groove 13. The interior of each of the two protrusions 7 is provided with a return spring 14. The two ends of the two return springs 14 are respectively fixedly connected to the outer wall of one side of the corresponding push block 5. The interior of each of the four first limiting block slots 12 is connected to the interior of the corresponding protrusion 7. The ends of each of the four push blocks 5 near the limiting block 11 are slidably extended into the interior of the first limiting block slot 12 and are respectively fixedly connected to the outer wall of the corresponding limiting block 11. The interior of each of the two protrusions 7 is slidably engaged with a limiting block 6. The outer walls of the two limiting blocks 6 are respectively in contact with the outer wall of one side of the corresponding push block 5. The two positioning components are used in conjunction and are set above and below the bracket 1.

[0031] Furthermore, when using this device and stacking lithium battery energy storage devices, the upper and lower positioning components need to be adapted and installed. The sliding groove 9 on the lower surface of the mounting base 3 is aligned with the protrusion 7 at the lower end of the bracket 1, so that the T-shaped block 10 on the protrusion 7 slides into the T-shaped block groove 8 in the sliding groove 9. At the same time, the protrusion 7 is inserted into the sliding groove 9. During the insertion process, the limiting blocks 11 on both sides of the protrusion 7 are squeezed by the inner wall of the sliding groove 9, pushing the push block 5 to compress the return spring 14 and slide into the push block groove 4. The limiting block 11 then retracts into the first limiting block groove 12. Then, when the mounting base 3 slides to align the first limiting block groove 12 with the second limiting block groove 13, the return spring 14 rebounds, pushing the push block 5 to drive the limiting block 11 to slide into the second limiting block groove 13, thus initially realizing the limiting and fixing of the mounting base 3 and the protrusion 7. Next, slide the limiting block 6 into the protrusion 7 so that its two ends contact the push block 5, thereby limiting the push block 5 a second time and preventing the limiting block 11 from disengaging from the second limiting block groove 13 due to external force. This completes the stable connection between the upper lithium battery body 2 and the bracket 1. Then, the installation principle of the lower positioning component is the same as that of the upper layer. It is connected to the bracket 1 or the support structure below through the same limiting structure. Finally, the assembly of the stacked lithium battery energy storage device is completed. If it is necessary to disassemble the lithium battery body 2 for maintenance or replacement, the operation is reversed. First, pull out the limiting block 6, push the push block 5 to compress the reset spring 14 and drive the limiting block 11 out of the second limiting block groove 13. Then, pull out the protrusion 7 along the T-shaped block groove 8 to remove the lithium battery body 2. The operation is convenient.

[0032] The precise guidance and limiting structure in the positioning component enables efficient and accurate alignment of the lithium battery body 2 during installation. During installation, simply align the sliding groove 9 on the lower surface of the mounting base 3 with the protrusion 7 at the lower end of the bracket 1. The sliding cooperation between the T-block 10 and the T-block groove 8 can quickly guide the mounting base 3 to slide in the correct direction, eliminating the need for workers to rely on experience and visual inspection for difficult alignment. Compared with traditional manual alignment methods, this significantly reduces the difficulty of operation, allowing even non-professionals to easily complete the installation. This significantly improves the installation efficiency of equipment in scenarios such as home energy storage and meets users' needs for flexibly adding or removing battery modules.

[0033] Structural Description: Bracket 1: As the basic support component of the entire stacking device, it is used to install the upper and lower positioning components and provide a stacking carrier for the lithium battery body 2. The lower two sides are fixedly installed with protrusions 7. The positioning and fixation of the lithium battery body 2 are achieved through the cooperation of the protrusions 7 and the mounting base 3.

[0034] The lithium battery body 2 is fixed on the upper surface of the mounting base 3 and is the core component of the energy storage device. It is connected to the bracket 1 through the positioning component to achieve multi-layer stacking and improve the energy storage capacity.

[0035] Mounting base 3: Used to support the lithium battery body 2. The lower surface has a sliding groove 9 that slides and engages with the protrusion 7. Through the cooperation of the T-shaped block groove 8 and the T-shaped block 10, and the second limiting block groove 13 and the limiting block 11, it achieves precise positioning and stable connection with the bracket 1. It is the connecting bridge between the lithium battery body 2 and the bracket 1.

[0036] Protrusion 7: Fixed on both sides of the lower end of bracket 1, with T-shaped block 10 fixed on the upper surface. Push block groove 4 and first limit block groove 12 are opened on the outer wall. Reset spring 14, installation push block 5, limit block 11 and limit block 6 are set inside. T-shaped block 10 and T-shaped block groove 8 cooperate to provide guidance for the sliding of mounting base 3. Push block 5 drives limit block 11 to be inserted into second limit block groove 13 under the action of reset spring 14 to achieve initial limit. Limit block 6 limits push block 5 a second time to enhance connection stability.

[0037] T-block 10 and T-block groove 8: T-block 10 is fixed on the upper surface of protrusion 7, and T-block groove 8 is opened inside the slide groove 9. The two slide together to provide guidance for the connection between mounting base 3 and protrusion 7, prevent mounting base 3 from shifting during sliding, and ensure accurate alignment of the limiting structure.

[0038] Push block 5 and reset spring 14: Push block 5 is slidably connected in push block groove 4. One end is fixed to limit block 11, and the other end is acted on by reset spring 14. The two ends of reset spring 14 are connected to push block 5. When mounting base 3 slides into place, the elastic force pushes push block 5 to drive limit block 11 into second limit block groove 13. It is the power component to achieve initial limit.

[0039] Limiting block 11: It is slidably connected in the first limiting block groove 12, one end is fixed to the push block 5, and the other end can slide into the second limiting block groove 13. By engaging with the second limiting block groove 13, it restricts the relative sliding of the mounting base 3 and the protrusion 7, thereby fixing the positioning component.

[0040] Limiting block 6: It slides and engages inside the protrusion 7, with both ends in contact with the push block 5. It is used to fix the position of the push block 5 and prevent the push block 5 from moving due to external forces (such as equipment vibration), causing the limiting block 11 to disengage from the second limiting block groove 13, thus playing a secondary limiting and reinforcing role.

[0041] Slide groove 9 and second limiting block groove 13: Slide groove 9 is opened on the lower surface of mounting base 3 to accommodate protrusion 7 and provide space for its sliding. T-shaped block groove 8 is opened inside for guidance. Second limiting block groove 13 is opened on both inner walls to cooperate with limiting block 11 to realize the limiting and fixing of mounting base 3 and protrusion 7.

[0042] First limiting block groove 12: It is formed on the outer walls of both sides of the protrusion 7 and corresponds to the second limiting block groove 13. It provides sliding space for the limiting block 11. Its interior is connected to the interior of the protrusion 7 to ensure the continuity of the push block 5 driving the limiting block 11 to move.

[0043] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
