[0029] Please also refer to Figures 1-5 This utility model provides an external household energy storage box, which includes an energy storage box, a box body 10 and a cover plate 20 covering the box body 10. The outer side of the box body 10 is provided with a hanging ring 30, a handle structure 40 and a hanging ear structure 50. The inner side of the box body 10 is provided with a detachable module box 60. The module box 60 is provided with two battery modules. Each battery module includes multiple batteries 73 arranged along the length of the module box 60.
[0030] In this embodiment, in order to facilitate the handling, installation and fixation of the energy storage device, a number of functional structures are provided on the outside of the housing 10, including lifting rings 30 for lifting, handle structures 40 for handling, and hanging ear structures 50 for wall mounting.
[0031] The enclosure 10 adopts a cuboid structure design with six sides: the two sides along the length are the front and back, the two sides along the width are the left and right sides, and the two sides along the height are the top and bottom. When facing the energy storage box, the side facing the operator is the front, and the side opposite it is the back (rear); the left and right sides of the front are the left and right sides, respectively; the top is the top surface, and the bottom is the bottom surface.
[0032] A module box 60 is provided inside the housing 10, which is used to accommodate and fix the battery modules. Two battery modules are housed within the module box 60, each including multiple batteries 73 arranged sequentially along the length of the module box 60. Specifically, the battery modules are arranged in a straight line, meaning that multiple batteries 73 are arranged sequentially along the length of the module box 60.
[0033] The module box 60, as an independent battery module housing structure, is detachably connected to the housing 10. This design allows for pre-assembly of the battery modules outside the energy storage box. During actual assembly, the batteries 73 are first placed into the module box 60 according to a predetermined arrangement. Since the module box 60 is separate from the housing 10, operators can complete this step on a flat surface such as a workbench, avoiding the inconvenience of assembling inside the energy storage box 10. After the batteries 73 are placed in sequence and arranged into two complete battery modules, the assembled module box 60 is then placed into the energy storage box 10.
[0034] This modular design has the following advantages: First, the pre-assembly method improves the efficiency and accuracy of battery 73 installation; second, the overall installation method reduces on-site operation time; third, when maintenance or replacement is required, the entire module box 60 can be directly removed for operation, avoiding complex disassembly and assembly work inside the box 10.
[0035] Through the above design, the external home energy storage box provided in this embodiment features a compact structure, convenient installation, and easy maintenance. The external functional structure of the box 10 meets the diverse needs of the energy storage device during transportation, installation, and use, while the internal modular design ensures the speed of battery module assembly.
[0036] In one embodiment, at least two lifting rings 30 are provided, and the lifting rings 30 are provided on the top of the housing 10.
[0037] In this embodiment, to meet the needs of hoisting operations during the installation and transportation of the energy storage device, two lifting rings 30 are symmetrically fixed to the top (top surface) of the housing 10. This dual-point lifting method makes the energy storage device more stable during hoisting, preventing tilting or swaying.
[0038] In practical applications, when it is necessary to hoist the energy storage device to the installation position, the hook of the lifting equipment can be connected to two lifting rings 30 at the same time to realize the smooth lifting and movement of the energy storage device, ensuring the reliability of the handling process.
[0039] In one embodiment, at least two handle structures 40 are provided, and the handle structures 40 are respectively provided on opposite sides of the housing 10.
[0040] In this embodiment, the energy storage box 10 has a handle structure 40 on both the left and right sides (i.e., opposite sides of the box 10). This symmetrical arrangement design takes into account the ease of use for operators during handling.
[0041] The handle structure 40 is positioned at a suitable height on both sides of the box 10, and has holes between it and the box 10, allowing two operators to easily grip it. Each handle structure 40 is fixedly connected to the box 10 by welding to ensure stability during handling.
[0042] In practical applications, when moving energy storage devices on the ground, operators can smoothly move the devices by gripping the handles 40 on both sides. This design meets the daily handling needs of energy storage devices while ensuring convenience during the process. The handle structure 40 is particularly important when it is necessary to adjust the position of the energy storage device or move it short distances in narrow areas where lifting equipment cannot be used.
[0043] In one embodiment, a suspension bracket for fixed connection with a support structure (not shown in the figures) is also included. At least two hanging ear structures 50 are provided, which are located on the back of the housing 10 and are used to hang on the suspension bracket.
[0044] In this embodiment, the supporting structure is specifically a wall. To achieve wall-mounted installation of the energy storage box, the energy storage device also includes a suspension bracket for fixed connection with the wall. The energy storage box body 10 is provided with two hanging ear structures 50 on the back (i.e., the rear), which are used to cooperate with the suspension bracket to achieve stable installation of the energy storage box.
[0045] Specifically, the hanging ear structure 50 adopts a symmetrical arrangement to ensure uniform force distribution. This wall-mounted design primarily considers the actual installation needs of home energy storage devices. Due to limited space in the home environment, wall-mounting saves floor space. The suspension bracket is designed to be fixedly connected to the wall, providing stable support for the energy storage box. During installation, the suspension bracket must be securely installed on the wall.
[0046] In actual installation, two operators are usually required to align the mounting lugs 50 of the energy storage box with the corresponding positions on the suspension bracket, and then slowly hang the energy storage box in place. After installation, the energy storage box will be fixed tightly against the wall.
[0047] In other embodiments, the supporting structure can be not only a wall, but also other structures that can provide sufficient load-bearing capacity, such as metal brackets, concrete columns, steel structural columns, etc.
[0048] In one embodiment, the ear-hanging structure 50 includes a fixing part 51 and an arm-shaped part 52. The fixing part 51 is fixedly connected to the housing 10. One end of the arm-shaped part 52 is connected to the fixing part 51, and the other end extends downward to form an extension. A gap is left between the extension of the arm-shaped part 52 and the fixing part 51.
[0049] In this embodiment, the hanging lug structure 50 of the energy storage box includes two main parts: a fixing part 51 and an arm-shaped part 52. The fixing part 51 is used to fix and connect to the box body 10 of the energy storage box, while the arm-shaped part 52 is used to cooperate with the suspension bracket.
[0050] Specifically, the fixing part 51 is fixedly connected to the back of the housing 10 by bolts (or welding). One end of the arm-shaped part 52 is connected to the fixing part 51, and the other end extends downward to form an extension. A certain gap is left between the extension of the arm-shaped part 52 and the fixing part 51, which helps to achieve the self-locking effect of the energy storage box, that is, under the action of the gravity of the housing 10, the arm-shaped part 52 will naturally and tightly cooperate with the suspension bracket.
[0051] During actual installation, align the extension of the arm-shaped part 52 with the corresponding structure on the suspension bracket; slowly lower the energy storage box so that the extension and the suspension bracket are properly engaged; fine position adjustments can be made through the gap between the extension and the fixing part 51 to ensure accurate installation.
[0052] In one embodiment, the suspension bracket includes a first connecting plate 53 and a second connecting plate 54 that are relatively fixed and spaced apart. The first connecting plate 53 is used to fix it to the wall. The second connecting plate 54 has a through hole 541 through it along the thickness direction. The extension of the arm-shaped part 52 can pass through the through hole 541 and one end of the arm-shaped part 52 overlaps in the through hole 541.
[0053] In this embodiment, the first connecting plate 53 and the second connecting plate 54 are relatively fixed, which can be achieved by setting a fixing plate 55 between them. Specifically, the suspension bracket has an overall C-shaped structure, including the first connecting plate 53 and the second connecting plate 54 on both sides and the fixing plate 55 in the middle. In this way, the first connecting plate 53 and the second connecting plate 54 are both relatively fixed and spaced apart. This design is mainly used to achieve stable wall-mounted installation of the energy storage box.
[0054] The first connecting plate 53 is used for fixed connection to the wall. During installation, the first connecting plate 53 can be firmly installed on the wall using fasteners such as expansion bolts. The second connecting plate 54 is the main functional plate, which has a through hole 541 extending through it along its thickness direction. The design of this through hole 541 matches the dimensions of the arm-shaped part 52 of the lug structure 50, so that the extension of the arm-shaped part 52 can be accurately inserted into the through hole 541, and one end of the arm-shaped part 52 can be reliably overlapped in the through hole 541. At this time, the extension of the arm-shaped part 52 passes through the gap between the first connecting plate 53 and the second connecting plate 54.
[0055] In actual installation, the operating steps are as follows: First, fix the suspension bracket to the wall using the first connecting plate 53 to ensure a secure installation; then, lift the energy storage box so that the hanging lug structure 50 on its back aligns with the through hole 541 on the second connecting plate 54; finally, slowly insert the extension of the arm-shaped part 52 into the through hole 541 and slowly lower the energy storage box until one end of the arm-shaped part 52 reliably overlaps the through hole 541. The entire installation process is simple, intuitive, and easy to operate.
[0056] In one embodiment, a roller assembly 80 is provided at the bottom of the housing 10.
[0057] In this embodiment, to facilitate the movement of the energy storage box on the ground, a roller assembly 80 is provided on the bottom surface (i.e., the underside) of the box 10. This design takes into account the practical needs of the energy storage device, which may require position adjustment or short-distance movement during daily use. This design with the roller assembly 80 at the bottom is particularly suitable for single-person operation. The operator can easily push or pull the energy storage device on the ground using the handle structure 40, thereby adjusting its position.
[0058] In one embodiment, the module box 60 includes a surrounding plate 61 and a sealing plate 62. Two battery modules are disposed inside the surrounding plate 61. Two sealing plates 62 are disposed at opposite ends of the surrounding plate 61 for fixing the battery modules.
[0059] In this embodiment, the enclosure 61 is used to form a space to accommodate the battery modules, and two battery modules are disposed on the inner side of the enclosure 61. Sealing plates 62 are respectively provided at opposite ends of the enclosure 61, and the battery modules are fixed by these two sealing plates 62.
[0060] Specifically, the enclosure 61 is designed to form a space that can accommodate two battery modules. Each battery module contains multiple batteries 73 arranged along the length of the enclosure 61. Once the battery modules are in place, they are secured by the end plates 62 to prevent them from shaking or shifting during use.
[0061] In the actual assembly process, firstly, a sealing plate 62 is fixed to one end of the enclosure 61. Then, the battery 73 is placed directly into the receiving space formed by the enclosure 61 from the top according to the predetermined position. Finally, another sealing plate 62 is fixed to the enclosure 61 after it abuts against the battery 73 inside the enclosure 61. After the battery module assembly is completed, the entire module box 60 can be placed into the energy storage box body 10.
[0062] In the actual assembly process, firstly, a sealing plate 62 is fixed to one end of the enclosure 61, thus forming a receiving space with an opening at the top and the other end. The operator can then directly insert the battery 73 into the receiving space formed by the enclosure 61 from the top.
[0063] After all batteries 73 are in place, insert another sealing plate 62 through the opening at the other end. As this sealing plate 62 is pushed in, it gradually comes into contact with the batteries 73 within the receiving space. By adjusting the position of the sealing plate 62, appropriate pressure can be applied to the batteries 73, ensuring a tight fit between adjacent batteries 73. Once the position is confirmed to be appropriate, the sealing plate 62 is fixedly connected to the surrounding plate 61, thus completing the fixation of the entire battery module.
[0064] A key advantage of this assembly method is that the module box 60 can be assembled outside the energy storage box. Once the battery modules are fully assembled and secured, the entire module box 60 is then placed inside the energy storage box's housing 10. This significantly simplifies the installation process and improves assembly efficiency. Furthermore, this modular design facilitates future maintenance and replacement.
[0065] In this embodiment, the enclosure 61 includes a bottom plate 611 and two side plates 612, which are disposed on opposite sides of the bottom plate 611. The side plates 612 are generally C-shaped with their openings facing outwards. Specifically, the top of the side plate 612 is configured as a first transverse plate-like structure 91, the top surface of which has a first fixing hole 92. Similarly, the inner side of the energy storage box 10 is provided with a second transverse plate-like structure 93, the top surface of which has a second fixing hole 94. When the module box 60 is installed into the energy storage box 10, the first fixing hole 92 and the second fixing hole 94 are aligned, and the two fixing holes can be fixed by bolts or other fasteners (not shown in the figures). This completes the assembly of the module box 60 and also completes the detachable connection between the module box 60 and the box 10.
[0066] In one embodiment, the top of the sealing plate 62 is provided with two grooves 621, and an insulating seat 63 is provided in the grooves 621. Signal acquisition components are respectively provided on the two battery modules, and the two ends of the signal acquisition components are respectively connected to the corresponding insulating seats.
[0067] In this embodiment, the signal acquisition component is mainly used to acquire and monitor the operating status information of the battery 73, including but not limited to parameters such as the voltage and current of the battery 73. The signal acquisition component includes an acquisition board 110 and a signal harness 111 connected thereto. Here, the acquisition board 110 is connected to the insulating base 63, and one insulating base 63 corresponds to one acquisition board 110. In practical applications, the insulating base 63 is first installed in the groove on the top of the sealing plate 62, and then the acquisition board 110 on the battery module is connected to the corresponding insulating base 63. The acquisition board 110 connected to the insulating base 63 at one end of the battery module is also connected to the main positive line and the main negative line. At the other end of the battery module, a connecting plate is set to connect the acquisition boards 110 of the first battery module 71 and the second battery module 72, and the connecting plate is fixedly connected to the insulating base 63 at that end.
[0068] In one embodiment, the groove 621 includes a communicating upper opening 622 and a lower receiving cavity 623, the width of the upper opening 622 being smaller than the width of the lower receiving cavity 623; the insulating seat 63 includes a connected head 631 and a limiting part 632, the width of the head 631 being smaller than the width of the limiting part 632, the head 631 passing through the upper opening 622, and the limiting part 632 being received in the lower receiving cavity 623, with a height difference between the limiting part 632 and the lower receiving cavity.
[0069] In this embodiment, the width of the upper opening 622 is designed to be smaller than the width of the lower receiving cavity 623, forming a stepped internal space. Correspondingly, the structure of the insulating base 63 also adopts a matching design, including a connected head 631 and a limiting part 632. The width of the head 631 is smaller than the width of the limiting part 632, and this dimensional relationship matches the structure of the groove 621. During installation, the head 631 of the insulating base 63 passes through the upper opening 622, while the limiting part 632 is received within the lower receiving cavity 623. A certain height difference is designed between the limiting part 632 and the lower receiving cavity. Specifically, the height of the limiting part 632 is smaller than the height of the lower receiving cavity 623.
[0070] In the specific implementation process, the insulating base 63 is inserted into the groove 621 from front to back. After the limiting part 632 is fully inserted into the lower receiving cavity 623, a preset height difference will remain between its top surface and the receiving cavity. This height difference is designed to ensure that the limiting part 632 has a certain vertical movement space after installation, so as to adapt to the position changes of the support plate and the signal acquisition components on it due to various factors.
[0071] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
