DETAILED DESCRIPTION

[0049] Clearly and completely describe the technical scheme in the embodiments of the utility model with reference to the drawings in the embodiments of the utility model, obviously, the described embodiments are only a part of the embodiments of the utility model, and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor belong to the scope of the utility model protection.

[0050] Please refer to Figures 1-5 The utility model provides the following technical scheme: a wall -hanging installation's energy storage equipment, including two upper and lower laminated arrangement's upper casing 1 and lower casing 2, fixed in the energy storage battery pack module 3 of upper casing 1, fixed in the micro inverter module 4 of lower casing 2, the bottom surface of upper casing 1 and the top surface of lower casing 2 are provided with the lead hole 5 that communicates, the left and right two side surfaces of upper casing 1 and lower casing 2 are all processed with the breathable micropore 10, still include: connecting mechanism 6, door plate 7, hanging plate 9, reverse L type support 11 and clamping mechanism 12.

[0051] Further, as shown in Figure 1 In the embodiment, the upper casing 1 is fixed to the top end of the lower casing 2 by two groups of symmetrically distributed connecting mechanisms 6, the door plates 7 are hinged to the open ends of the upper casing 1 and the lower casing 2, and the door plates 7 are locked after being closed by the locking mechanisms 8, the hanging plate 9 is fixed to the top end of the upper casing 1, and the hanging holes 91 are formed in the hanging plate 9, the reverse L-shaped supports 11 are fixed to the wall surface by the adhesive layers 111 for supporting the lower casing 2, and the clamping mechanisms 12 are installed at the top ends of the reverse L-shaped supports 11 for clamping the lower casing 2. After using the above scheme, the load-bearing wall (such as a concrete wall) is selected, the installation position is marked by a level, and the levelness of the reverse L-shaped supports 11 is ensured.

[0052] For the position of the hanging hole 91, a screw is drilled into the wall surface, then the wall surface installation area is cleaned, and the reverse L-shaped support 11 is pasted to the wall surface by the adhesive layer 111, wherein the adhesive layer 111 is a 3M VHB adhesive tape, and the load-bearing capacity is greater than or equal to 50 kg.

[0053] The hanging hole 91 of the hanging plate 9 is aligned with the screw drilled into the wall surface in advance, the screw penetrates the hanging hole 91, and the energy storage equipment is hung on the screw.

[0054] The clamping mechanism 12 is started, the lower casing 2 is clamped by the clamping mechanism 12, the stable installation of the energy storage equipment can be realized, and the energy storage battery pack module 3 is connected with the micro inverter module 4 through the lead hole 5.

[0055] Through the above design, the wall-mounted energy storage equipment realizes three core advantages of convenient installation, efficient heat dissipation and safety protection, is suitable for distributed photovoltaic energy storage, emergency backup power supply and the like scenes, and helps household and industrial and commercial users to realize energy self-management.

[0056] The energy storage device of this utility model adopts a modular design, with an upper shell 1 and a lower shell 2, which are used to install the energy storage battery pack module 3 and the micro inverter module 4, respectively. The module can be inspected and maintained by opening the corresponding door panel 7, which is more convenient and safer.

[0057] The energy storage device is supported by an inverted L-shaped bracket 11 that is fixed by adhesive bonding and clamped by a clamping mechanism 12, which reduces the number of holes to be drilled in the wall while ensuring stable installation.

[0058] Optionally, by Figures 1-3 As shown, in this embodiment, the clamping mechanism 12 includes: a positioning block 121, an inverted L-shaped locking block 122, a fixing plate 123, a bidirectional threaded rod 124, and a regular hexagonal knob 125. Two positioning blocks 121 are symmetrically fixed to the bottom of the outer side of the lower housing 2, and each positioning block 121 has a positioning groove 1211. Two inverted L-shaped locking blocks 122 are symmetrically distributed, and the horizontal portion of each inverted L-shaped locking block 122 is embedded in the positioning groove 1211. Two fixing plates 123 are symmetrically fixed to the top surface of the inverted L-shaped bracket 11. The bidirectional threaded rod 124 is rotatably mounted between the two fixing plates 123, and the bidirectional threaded rod 124 passes through the inverted L-shaped locking block 122 and engages via a threaded connection. Connected to the inverted L-shaped locking block 122, the hexagonal knob 125 is fixed to one end of the bidirectional threaded rod 124. With the above scheme, when the energy storage device is suspended on the screw, the horizontal part of the inverted L-shaped locking block 122 is aligned with the positioning groove 1211. At this time, the hexagonal knob 125 is turned with a wrench to rotate the bidirectional threaded rod 124. Since the bidirectional threaded rod 124 is connected to the inverted L-shaped locking block 122 by the thread engagement, the rotation of the bidirectional threaded rod 124 will be converted into the linear movement of the two inverted L-shaped locking blocks 122, causing the two inverted L-shaped locking blocks 122 to move closer to the inward side until the horizontal part of the inverted L-shaped locking block 122 is embedded in the positioning groove 1211 to achieve locking.

[0059] Through the above design, the clamping mechanism 12 achieves the core objectives of rapid installation, high-stability clamping, and tool-free maintenance. Together with the suspension structure of the hanging plate 9, it forms a double-insurance fixing system to ensure the long-term reliability of the energy storage equipment installed on the wall.

[0060] Preferably, by Figures 1-3 As shown in this embodiment, the clamping mechanism 12 further includes: guide rods 126. Two guide rods 126 are symmetrically fixed between two fixed plates 123, and the guide rods 126 pass through the inverted L-shaped locking block 122. With the above solution, when in use, the inverted L-shaped locking block 122 has a guide hole and forms a clearance fit with the guide rods 126, which allows axial sliding but restricts radial swing.

[0061] When the hexagonal knob 125 is rotated, the bidirectional threaded rod 124 drives the inverted L-shaped locking block 122 to move axially. The guide rod 126 restricts the rotation of the inverted L-shaped locking block 122 around the bidirectional threaded rod 124, eliminating the lateral displacement caused by the backlash of the thread pair in the traditional single threaded rod transmission.

[0062] Optionally, by Figure 1 and Figure 4 As shown, in this embodiment, the connecting mechanism 6 includes: a lower connecting plate 61, an upper connecting plate 62, a threaded post 63, and a locking nut 64. The lower connecting plate 61 is fixed to the top of the outer side of the lower housing 2, and the upper connecting plate 62 is fixed to the bottom of the outer side of the upper housing 1. A through hole 621 is provided on the upper connecting plate 62. The threaded post 63 is fixed to the top surface of the lower connecting plate 61 and passes through the through hole 621. The locking nut 64 is installed on the protruding end of the threaded post 63 by thread engagement. With the above scheme, the structure is used to realize the quick and stable assembly of the upper housing 1 and the lower housing 2 during use.

[0063] When installing the upper housing 1 onto the top of the lower housing 2, first ensure that the upper housing 1 and the lower housing 2 are accurately aligned, so that the upper connecting plate 62 and the lower connecting plate 61 are parallel to each other and completely correspond, ensuring that the through hole 621 on the upper connecting plate 62 can be accurately aligned with the threaded post 63 on the top surface of the lower connecting plate 61.

[0064] Slowly lower the upper housing 1 so that the threaded post 63 can pass smoothly through the through hole 621. During this process, avoid collision between the threaded post 63 and the edge of the through hole 621 to prevent damage to the threads.

[0065] After the threaded post 63 has completely passed through the through hole 621, tighten the locking nut 64 onto the protruding end of the threaded post 63 to apply pressure and lock it in place.

[0066] When maintenance, repair, or replacement of the energy storage battery pack module 3 or the micro inverter module 4 inside the equipment is required, the upper housing 1 can be easily separated from the lower housing 2 simply by using a wrench to loosen the locking nut 64. This detachable connection method greatly improves the maintainability of the equipment and reduces maintenance time and costs. For example, if the energy storage battery pack module 3 malfunctions, the operator can quickly disassemble the upper housing 1 or simply open the corresponding door panel 7 to directly inspect and repair the energy storage battery pack module 3 without damaging the entire structure of the equipment.

[0067] Optionally, by Figure 1 and Figure 5As shown, in this embodiment, the locking mechanism 8 includes: a limiting block 81, a flip screw 82, and a wing nut 83. The limiting block 81 is fixed to the free end of the door panel 7, and a notch 811 is provided on the limiting block 81. The flip screw 82 is hinged to the outer wall of both the upper housing 1 and the lower housing 2, and the flip screw 82 passes through the notch 811. The wing nut 83 is installed on the protruding end of the flip screw 82 by thread engagement. With the above scheme, when it is necessary to close the door panel 7 of the upper housing 1 or the lower housing 2, the door panel 7 is rotated around its hinge axis to the closed position.

[0068] The rotating screw 82, which is hinged to the outer wall of the upper housing 1 and the lower housing 2, is rotated around its hinge point so that it passes through the notch 811 opened on the limiting block 81.

[0069] After the reversing screw 82 has completely passed through the notch 811, screw the wing nut 83 onto the protruding end of the reversing screw 82.

[0070] The locking mechanism 8 uses a combination of a wing nut 83 and a flip screw 82. No additional tools are required, and operators can directly lock and unlock the door panel 7 by hand. This convenient operation method improves the efficiency of equipment maintenance and repair, especially when the door panel 7 needs to be opened and closed frequently, which can save a lot of time and effort.

[0071] Preferably, by Figure 1 As shown, this embodiment also includes a transparent observation window 71, which is embedded and fixed on the door panel 7. With the above solution, when in use, the two transparent observation windows 71 are respectively facing the SOC display screen of the energy storage battery pack module 3 and the operation indicator light of the micro inverter module 4, making it easy to observe the status of the energy storage battery pack module 3 and the micro inverter module 4.

[0072] Preferably, by Figure 1 and Figure 2 As shown, this embodiment also includes: corner bracing blocks 112 and rubber support strips 113. Multiple corner bracing blocks 112 are fixed at equal intervals between the horizontal and vertical parts of the inverted L-shaped bracket 11, and two rubber support strips 113 are symmetrically fixed to the top surface of the inverted L-shaped bracket 11. With the above solution, when in use, multiple corner bracing blocks 112 greatly improve the load-bearing capacity of the inverted L-shaped bracket 11 through the principle of triangular mechanics.

[0073] Two rubber support strips 113 are used to elastically support the energy storage device. Through elastic deformation, they achieve three functions: vibration isolation, leveling, and anti-slip, protecting the precision components inside the energy storage device.

[0074] Preferably, by Figure 1 and Figure 2As shown, this embodiment also includes a thermally conductive silicone sheet 13. Thermally conductive silicone sheets 13 are bonded and fixed on the back of both the upper housing 1 and the lower housing 2. With the above solution, when in use, the energy storage battery pack module 3 and the micro inverter module 4 generate heat that is conducted to the outer shell and then conducted to the wall through the thermally conductive silicone sheet 13. The heat is then dissipated through heat conduction on the wall and air convection.

[0075] The circuit connection involved in this utility model is a common method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. It belongs to the widely used prior art.

[0076] Components not described in detail in this article are existing technologies.

The module can be inspected and maintained by opening the corresponding door panel 7, which is more convenient and safer.

[0078] The energy storage device is supported by an inverted L-shaped bracket 11 that is glued and fixed, and clamped by a clamping mechanism 12, which reduces the number of holes to be drilled in the wall while ensuring installation stability.

[0079] During installation, the upper housing 1 and the lower housing 2 are first stably assembled using the connecting mechanism 6;

[0080] Next, select a load-bearing wall, mark the installation position with a level, and ensure the horizontality of the inverted L-shaped bracket 11;

[0081] For the position of the mounting hole 91, drive screws into the wall, then clean the wall installation area, and stick the inverted L-shaped bracket 11 to the wall using the adhesive layer 111;

[0082] Align the mounting hole 91 of the mounting plate 9 with the screw that has been driven into the wall beforehand, so that the screw passes through the mounting hole 91, and suspend the energy storage device on the screw.

[0083] Start the clamping mechanism 12, and the lower housing 2 will be clamped by the clamping mechanism 12 to achieve stable installation of the energy storage device. The energy storage battery pack module 3 is connected to the micro inverter module 4 through the lead hole 5.

[0084] Through the above design, this wall-mounted energy storage device achieves three core advantages: convenient installation, efficient heat dissipation, and safety protection. It is suitable for scenarios such as distributed photovoltaic energy storage and emergency backup power, helping residential and commercial users to achieve autonomous energy management.
