[0002] An inverter is a power regulation device composed of semiconductor devices, mainly used to convert DC power into AC power. It is generally composed of a boost circuit and an inverter bridge circuit. The boost circuit boosts the DC voltage of the solar cell to the DC voltage required for the inverter output control; the inverter bridge circuit converts the boosted DC voltage into an AC voltage of a common frequency.

[0003] With the growing demand for photovoltaic inverters and the rich application scenarios, there is a trend of miniaturization of inverters.

[0033] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the relevant utility model are shown in the accompanying drawings. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0035] The utility model provides a double-locking wall-mounted structure of a micro inverter, such as Figures 1 to 8 As shown, it includes a wall-mounted base plate 1 and an inverter body 2, and the inverter body 2 includes an inverter housing 3 for matching with the wall-mounted base plate.

[0036] A plurality of coupling mechanisms 4 for coupling and assembling the inverter housing 3 and the wall-mounted bottom plate 1 are provided between the outer periphery of the inverter housing 3 and the wall-mounted bottom plate.

[0037] The matching mechanism 4 includes a clamping portion 5 arranged on the wall-mounted base plate and a matching pile platform 6 arranged on the inverter housing for matching with the clamping portion. A first locking portion 7 for fitting and locking the inverter housing and the wall-mounted base plate and a second locking portion 8 for locking the inverter housing and the wall-mounted base plate to form a heat dissipation gap are provided between the clamping portion 5 and the matching pile platform 6.

[0038] Specific implementation process and principle description:

[0039] The matching assembly between the wall-mounted base plate 1 and the inverter body 2 can be achieved through the matching mechanism 4, and the design of the first locking portion 7 and the second locking portion 8 can meet the requirements of the fitting assembly and the interval heat dissipation assembly of the two.

[0040] Specifically, refer to Figure 1 and Figure 2 As shown, the wall-mounted base plate 1 and the inverter body 2 are assembled together. At this time, the first locking part 7 locks the wall-mounted base plate 1 and the inverter body 2 together. At this time, the first locking part 7 is in a locking state for both, and the second locking part 8 is in a loose state.

[0041] Reference Figure 3 and Figure 4As shown, it is an assembly structure in which the wall-mounted base plate 1 and the inverter body 2 are spaced apart for heat dissipation. At this time, the second locking portion 8 locks the two apart, and the first locking portion 7 is a non-locking structure.

[0042] In this way, during the packaging and transportation process, the close-fitting and locking structure is adopted, which has a small volume and can effectively avoid shock, so that the transportation cost is reduced. When in use, the interval locking method is adopted to meet its heat dissipation requirements, so that the performance of the micro inverter is improved.

[0043] In a specific embodiment, the first locking portion 7 includes two oppositely arranged first snap arms 71 arranged on the pile portion, two first snap grooves 72 arranged on the matching pile platform and corresponding to the first snap arms, and a first locking platform 73 arranged between the two first snap grooves.

[0044] The second locking portion 8 includes two second buckle arms 81 arranged opposite to each other on the pile portion, two second buckle grooves 82 arranged on the matching pile platform and corresponding to the second buckle arms, and a second locking platform 83 arranged between the two second buckle grooves.

[0045] Specifically, this embodiment adopts a design in which the first locking portion 7 and the second locking portion 8 are separated, that is, the first locking portion 7 performs separate fitting locking, and the second locking portion 8 performs separate interval locking. When the first locking portion 7 is locking, the second locking portion 8 is in a loose state. Conversely, when the second locking portion 8 is locking, the first locking portion 7 is in a loose state, thus meeting the locking requirements of two different locking states.

[0046] The first locking portion 7 and the second locking portion 8 are explained. Generally, the demand can be met by using two locking structures with different strokes, such as locking by a locking pin, locking by a bolt, locking by a snap, etc. As long as the locking structure can meet the two states of fitting and spacing, it is within the protection scope of this case.

[0047] The matching assembly structure of the snap arm and the snap groove is the preferred embodiment of the present invention, which meets the requirements of detachable assembly and disassembly, is easy to form and produce the first locking part 7 and the second locking part 8, and has a simple structure and controlled costs.

[0048] In a specific embodiment, the first locking platform 73 and the second locking platform 83 are an integrated shared locking platform.

[0049] For specific instructions, refer to Figures 1 to 8As shown, the first locking platform 73 and the second locking platform 83 are an integrated shared locking platform, and the shared locking platform shares two locking positions. When locking in close contact, the first snap arm limits and locks the exposed surface of the shared locking platform. When locking the second locking position, the first snap arm of the release platform releases the shared locking platform, so that the wall-mounted base plate 1 and the inverter body 2 are separated. At this time, the second snap arm limits and locks the exposed surface of the shared locking platform to meet the interval locking requirements.

[0050] The positions of the two first buckle arms and the two second buckle arms are described. The relative direction of the two first buckle arms and the relative direction of the two second buckle arms can be parallel or cross-distributed, thus meeting the common compatibility requirements of the common locking platform.

[0051] In a specific embodiment, a group of opposite side walls of the common locking platform are respectively provided with first buckle grooves, and another group of opposite side walls are respectively provided with second buckle grooves.

[0052] This embodiment is a preferred structure, which adopts a layout method of crossing relative directions, so that the combination of the first locking part 7 and the second locking part 8 is more compact and ingenious.

[0053] In a specific embodiment, the first latch arm 71 is provided with a limiting latch body 711 for locking the inverter housing and the wall-mounted base plate together, and a locking support free end 712 for supporting the bottom locking of the common locking platform when the inverter housing and the wall-mounted base plate are locked in a spaced relationship.

[0054] Specifically, when the fitting locking is performed, the exposed surface of the common locking platform is limited by the limiting buckle body 711, and when the interval locking is performed, the inverter housing is pulled outward so that the common locking platform is separated from the limiting buckle body 711 and is limited by the second buckle arm 81. At this time, the free end of the first buckle arm 71 is elastically reset so that the free end 712 of the locking support supports the bottom wall of the common locking platform, thereby achieving reliable locking of the interval heat dissipation locking state.

[0055] It should be noted that the locking support free end 712 is designed to increase the stability of the interval locking, and is also a design that cleverly combines the first locking portion 7 and the second locking portion 8.

[0056] Of course, stable locking can also be achieved by designing a limiting protrusion on the second buckle arm 72 for the bottom wall of the common locking platform. It only needs to meet the double limiting structure design of the top wall and the bottom wall of the common locking platform in the interval locking state, which is within the protection scope of this case.

[0057] In a specific embodiment, the clamping pile portion 5 is provided with a hollow portion 50 for being arranged opposite to the common locking platform.

[0058] Specifically, the first snap arm and the second snap arm are both relatively inclined deformation structures. Through the hollow portion 50, the ejection of the top column can be achieved, thereby realizing the opening operation of the relative snap arms, playing the role of unlocking and disassembly, thus facilitating assembly and disassembly operations.

[0059] More specifically, when the wall-mounted base plate 1 and the inverter body 2 are assembled, the top column passes through the hollow portion 50 to force the first buckle arm and the second buckle arm to separate. At this time, after the fitting assembly, the top column is withdrawn, and the first buckle arm is deformed and reset to achieve fitting and locking. When disassembling, the first buckle arm and the second buckle arm are also separated through the top column, which facilitates the disassembly of the two.

[0060] When changing from the fitted state to the separated locked state, the inverter body 2 is directly pulled so that the common locking platform passes through the limiting buckle body 711 to achieve the separated locking.

[0061] In a specific embodiment, a plurality of corner guide bodies 9 for guiding the assembly of the inverter housing are provided on the wall-mounted base plate 1 .

[0062] The corner end guide body 9 satisfies the guiding requirement for relative assembly between the wall-mounted base plate 1 and the inverter body 2 .

[0063] In a specific embodiment, Figures 1 to 8 As shown, two matching piles are respectively provided on a set of opposite side walls of the inverter housing.

[0064] It is a double-sided locking structure. Of course, the use of other distributed structures that can achieve fit locking and interval locking is also within the protection scope of this case, such as setting a matching pile platform on each side wall.

[0065] In a specific embodiment, the matching pile platform is a structure integrally formed on the inverter housing, which meets the structural strength requirements of integral molding and is easy to process and produce.

[0066] From the above description, it can be found that the utility model meets the requirements of locking and providing heat dissipation gaps, which is convenient for packaging and transportation during lamination and heat dissipation during use. The cleverly combined matching mechanism design has a compact structure and reliable and stable double lock retention, and is easy to install and disassemble. The installation is relatively simple and quick, the structure is compact, and it is easy to manufacture and promote application.

[0068] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
