DETAILED DESCRIPTION

[0024] In order to have more clearly understood the technical features, the object and the effect of the utility model, now the specific implementation mode of the utility model is explained in detail with reference to the drawings.

[0025] Clearly, the described embodiments are merely a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative effort fall within the scope of the present application.

[0026] Please refer to Figures 1 to 6 The utility model discloses an easy-to-install suspension type micro inverter 100. The easy-to-install suspension type micro inverter 100 comprises a shell and an electrical device arranged in the shell. The shell is provided with a plurality of connecting heads 3 on the left and right sides, which are used to electrically connect the electrical device in the shell with other electrical components outside the shell, such as photovoltaic panels, electrical components, power grids, etc. The electrical device is a component required to realize the inverter function and additional functions, including but not limited to PCB boards, electronic components thereon, controllers, etc. The present application does not involve improvement of the electrical device. The micro inverter 100 described in the present application comprises an electrical device that can be implemented according to the existing scheme, and the present application does not limit this.

[0027] The present application mainly relates to improvement of the shell of the micro inverter 100 to facilitate installation of the micro inverter 100. In the present application, the shell comprises a shell main body 1 and a handle 2 extending upward from the upper end of the shell main body 1. The handle 2 comprises a transversely extending holding handle 21 and connecting walls 22 extending longitudinally from both ends of the holding handle 21 to be connected to the shell main body 1. The holding handle 21 and the connecting walls 22 enclose a holding space 23 for inserting fingers. One of the two connecting walls 22 is provided with a first suspension hole 201 and a communication hole 203 opening inward from the side end of the connecting wall 22 away from the holding space 23 to communicate with the first suspension hole 201; the holding handle 21 or the other of the two connecting walls 22 is provided with a second suspension hole 202, which communicates with the holding space 23.

[0028] The easy-to-install suspended micro-inverter 100 provided by this utility model allows installers to lift the handle 2 with one hand for installation, eliminating the need to drag the micro-inverter 100 with both hands, thus facilitating the application of force and installation operation. Furthermore, the suspension holes 201, 202, and connecting holes 203 for suspending the micro-inverter 100 are all located on the handle 2, close to the installer's hand, making it easy for the installer to visually observe and align the installation. On the other hand, since the second suspension hole 202 is connected to the gripping space 23, the micro-inverter 100 can be pre-suspended on one side during installation. This allows the installer to focus only on the alignment of the first suspension hole 201, without needing to ensure that multiple suspension holes are suspended simultaneously, greatly reducing the installation difficulty.

[0029] Please see Figures 1 to 4 The illustration shows a first embodiment of the easily installable suspended micro-inverter 100 of this application. In this embodiment, the handle 2 is frame-shaped and is located at the upper end of the housing body 1. The width of the grip 21 is smaller than the width of the connecting wall 22. The grip 21 is a horizontally extending strip, and its width refers to its dimension in the vertical direction. Its width should not be too large, just enough for a normal-sized hand to grasp and hold; at the same time, its width should not be too small, so as to avoid insufficient gripping by a normal-sized hand, resulting in an unstable grip. The connecting wall 22 is a vertically extending plate, and its width refers to its dimension in the horizontal direction. Its width should not be too small, as this would result in insufficient connection strength and would also be detrimental to the opening of the first suspension hole 201. Therefore, in this embodiment, the width of the grip 21 is set to about 2 cm, and the width of each connecting wall 22 is set to about 4 cm.

[0030] In this embodiment, the handle 2 and the shell body 1 are integrally formed. The integrally formed structure has high strength and reduces the number of scattered parts, facilitating manufacturing. In this embodiment, the shell is a metal part, such as a cast aluminum part, and the handle 2 and the shell body 1 are integrally cast. Please refer to [link to previous text]. Figure 1 and Figure 2As shown, the front of the housing body 1 is provided with several heat dissipation fins, and the back of the housing body 1 is an opening. The micro inverter 100 also includes a back cover plate 4 covering the opening. The front refers to the side of the micro inverter 100 that faces outwards after installation, i.e., towards the installer, or the side that the installer or user frequently sees. The heat dissipation fins on the front enhance the heat dissipation performance of the micro inverter 100. In this embodiment, the heat dissipation fins are also integrally formed with the housing body 1. The back refers to the side opposite to the front, i.e., the side where the micro inverter 100 is in contact with the installed components. For example, in some embodiments, the micro inverter 100 is suspended on a wall, and the back is the side in contact with the wall. The opening on the back is used for the assembly, disassembly, and maintenance of the electrical components inside the housing. The back cover plate 4 is fastened to the housing with screws. Furthermore, to improve sealing performance, sealing rings can be provided at the edges of the openings of the back cover plate 4 and the housing to provide a waterproof seal.

[0031] Please see Figure 1 As shown, the first suspension hole 201 and the connecting hole 203 are connected to form an L-shape. In this embodiment, the first suspension hole 201 is a longitudinal through hole, and the connecting hole 203 is a transverse through hole. The connection hole 203 and the first suspension hole 201 are connected to form an L-shape. The outer opening of the connecting hole 203 is an open opening communicating with the outside, allowing the suspension pin that mates with the first suspension hole 201 to enter the first suspension hole 201 transversely through the connecting hole 203. Figure 1 Taking the shown perspective as an example, the first suspension hole 201 is formed on the connecting wall 22 located on the right side. The right end of the connecting wall 22 is the end facing away from the gripping space 23, and its left end is the end facing the gripping space 23. The connecting hole 203 extends from the right end of the connecting wall 22 to the left end, penetrating the right end but not penetrating to the left end.

[0032] The second suspension hole 202 extends upward from the lower edge of the grip handle 21. The second suspension hole 202 communicates with the grip space 23. During installation, the suspension pin that mates with the second suspension hole 202 can be initially positioned anywhere within the grip space 23 to contact and support the grip handle 21, providing a one-sided pre-suspension function. This facilitates the installer's one-sided alignment of the suspension pin with the first suspension hole 201. To achieve balanced and stable support at two points, the second suspension hole 202 is located on the grip handle 21 away from the first suspension hole 201. In this embodiment, as a further improved technical solution, the second suspension hole 202 extends upward from the connection point between the grip handle 21 and another connecting wall 22, such that the side of the connecting wall 22 facing the grip space 23 forms one side wall of the second suspension hole 202, and the second suspension hole 202 and the grip space 23 communicate to form an L-shape. With this configuration, it is easy to quickly align and engage the suspension pin with the second suspension hole 202. Simply make the suspension pin pass through the holding space 23, and then move the micro inverter 100 to the right until the suspension pin is blocked by the leftmost wall of the holding space 23 and cannot move any further. Then, put down the micro inverter 100, and the suspension pin will enter the second suspension hole 202, completing the suspension engagement.

[0033] In another embodiment, the second suspension hole 202 may also be configured to be formed on the other of the two connecting walls 22, and connected to the gripping space 23 through a communicating groove formed from the side end of the connecting wall 22 toward the gripping space 23. Still using Figure 1 Taking the shown perspective as an example, the second suspension hole 202 can be opened on the connecting wall 22 located on the left side. The right end of the connecting wall 22 faces the gripping space 23, and the left end faces away from the gripping space 23. The connecting groove extends from the right end of the connecting wall 22 to the left end. The connecting groove passes through the right end and communicates with the gripping space 23, but does not pass through to the left end.

[0034] Furthermore, such as Figure 1 As shown, the handle 2 is also provided with a housing grounding hole 221. The housing grounding hole 221 can ground the housing through a conductive element to improve the electrical safety performance of the housing.

[0035] For further details, please refer to Figure 4As shown, the housing body 1 has an indicator light hole for mounting the indicator light cover 12. A protruding guide boss 11 is provided on the outer side of the indicator light hole, and a guide surface 111 is provided on the inner wall of the guide boss 11. In this embodiment, the guide surface 111 is a gradually tapering slope from the outside to the inside, which guides the installation of the indicator light cover 12. The indicator light cover 12 is generally cylindrical, with several elastic pieces and annular ribs at its tail end to limit its position after installation and prevent it from falling out of the indicator light hole. The indicator light is located inside the indicator light cover 12, emitting an indicator light through it. After the indicator light cover 12 is installed inside the guide boss 11, a narrow space is formed between the inner wall of the guide boss 11 at the outer side of the guide surface 111 and the peripheral wall of the indicator light cover 12. This space can be filled with sealant to increase the sealing performance at the indicator light hole.

[0036] Please see Figure 5 The illustration shows a second embodiment of the micro-inverter 100 of this application. The main difference between this embodiment and the first embodiment lies in the shape of the lower edge of the grip 21. In both embodiments one and two, the lower edge of the grip 21 is wavy. This wavy shape conforms to human fingers, increasing grip comfort and anti-slip performance. In embodiment one, the wavy shape is formed by a single arc extending repeatedly in the horizontal direction; in embodiment two, the wavy shape is a wavy shape extending upwards from left to right in the horizontal direction, with each arc segment having a different shape. Please refer to [link / reference]. Figure 6 As shown, this is an illustration of Embodiment 3 of the micro inverter 100 of this application. The main difference between it and Embodiment 1 is the shape of the lower edge of the grip 21. In this embodiment, the lower edge of the grip 21 is a straight edge.

[0037] For other parts not mentioned in Embodiments 2 and 3, please refer to Embodiment 1 for the settings, which will not be repeated here.

[0038] As can be seen from the above description of multiple embodiments, the easy-to-install suspended micro inverter 100 provided by this utility model includes a handle 2 having a gripping space 23. The handle 2 is provided with a first suspension hole 201 and a second suspension hole 202. One of the two connecting walls 22 included in the handle 2 is provided with the first suspension hole 201 and a connecting hole 203 that extends inward from the side end of the connecting wall 22 away from the gripping space 23 and communicates with the first suspension hole 201. The grip handle 21 or the other of the two connecting walls 22 is provided with the second suspension hole 202, and the second suspension hole 202 communicates with the gripping space 23. This design allows installers to lift the handle 2 with one hand for installation without having to use both hands. Moreover, the suspension holes and other structures for suspending the micro-inverter 100 are all located on the handle 2, making it easy to observe and align. On the other hand, since the second suspension hole 202 is connected to the gripping space 23, the micro-inverter 100 can be pre-suspended on one side during installation using the gripping space 23, without having to ensure that multiple suspension positions are suspended simultaneously. This greatly reduces the difficulty of installation and improves the efficiency of disassembly and assembly.
