[0039] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.
[0040] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.
[0041] Please refer to Figures 1-4 , Figure 1 This is a schematic diagram of the inverter housing 100 provided in this embodiment; Figure 2 This is a cross-sectional view of the inverter housing 100 provided in this embodiment; Figure 3 for Figure 1 A magnified view of a section at point A in the middle; Figure 4 for Figure 2 A magnified view of a section at point B in the middle;
[0042] This embodiment also provides an inverter, which includes electrical components and an inverter housing 100, with the electrical components housed within the inverter housing 100. The inverter housing 100 includes a shell 110 and a cover 120; the shell 110 is provided with a accommodating cavity 111 and an opening 112 that communicate with each other; the accommodating cavity 111 is used to accommodate the electrical components; the opening 112 is used for the electrical components to pass through; the cover 120 is used to open or close the opening 112; one end face of the opening 112 and the end face of the cover 120 are provided with a glue storage tank 130, and the other end face is provided with at least one extrusion member 140; the extrusion member 140 is located within the glue storage tank 130; the glue storage tank 130 accommodates a gel layer 150, which wraps around the extrusion member 140; the gel layer 150 is used to fill the gap between the shell 110 and the cover 120.
[0043] Specifically, in this embodiment, the housing 110 is provided with an adhesive reservoir 130, and the cover 120 is provided with an extrusion member 140. It should be noted that when filling the adhesive reservoir 130 with adhesive, the space inside the reservoir 130 is not completely filled, but only a portion is filled to avoid excessive adhesive and to prevent adhesive from overflowing into the receiving cavity 111 when the housing 110 and the cover 120 are closed, which could affect the electrical components inside the receiving cavity 111.
[0044] Understandably, the amount of adhesive filled into the adhesive reservoir 130 is limited. In order for the adhesive to seal the gap between the housing 110 and the cover 120, this embodiment provides a pressing member 140 on the cover, so that during the closing process, the adhesive flows upward and overflows into the gap between the housing 110 and the cover 120. After the adhesive solidifies, it forms a gel layer 150. This embodiment utilizes the gel layer 150 to prevent external impurities from entering the receiving cavity 111 through the gap between the housing 110 and the cover 120, thereby avoiding the impact of impurities on the operation of electrical components and improving the protection effect on electrical components.
[0045] Please refer to Figure 5 , Figure 5 This is an exploded view of the inverter housing 100 provided for other embodiments. In other embodiments, the glue reservoir 130 may also be disposed on the cover 120, and the extrusion member 140 may also be disposed on the housing 110. In this case, when installing the housing 110, the cover 120 needs to be placed below the housing 110, so that the housing 110 and the cover 120 are closed together. It should be noted that the electrical components are fixedly connected to the inner wall of the housing 110, therefore, the electrical components will not fall off.
[0046] For further information, please refer to the following: Figures 1-4In this embodiment, the extruder 140 includes a connecting portion 141 and at least one anti-detachment portion 142; one end of the connecting portion 141 is connected to the end face of the opening 112 or the end face of the shell cover 120, and the other end of the connecting portion 141 is connected to the anti-detachment portion 142; the anti-detachment portion 142 extends outward from the connecting portion 141; wherein, the gel layer 150 wraps the connecting portion 141 and the anti-detachment portion 142.
[0047] Specifically, the end of the extruder 140 that extends into the glue storage tank 130 is provided with an anti-detachment part 142. Since the anti-detachment part 142 extends outward from the connecting part 141, the extruder 140 has a hook-like structure. Furthermore, during the closing process of the housing 110 and the cover 120, the glue is squeezed and flows by the extruder 140. After the glue solidifies to form a gel layer 150, the gel will fill the glue storage tank 130 and wrap around the extruder 140.
[0048] Understandably, because the extruder 140 is shaped like a hook, the adhesive gradually forms a groove during the solidification process, which engages with the anti-detachment part 142 of the extruder 140, thereby causing the gel layer 150 to adhere to the extruder 140. Thus, this embodiment utilizes the interaction of various forces generated by the interlocking between the gel layer 150 and the anti-detachment part 142, as well as the adhesiveness of the gel layer 150, to improve the connection stability between the housing 110 and the cover 120, preventing the housing 110 from detaching from the cover 120.
[0049] According to the above configuration, in this embodiment, there are two anti-detachment parts 142. The two anti-detachment parts 142 are arranged in a ring array around the center line of the connecting part 141 to further improve the connection stability of the housing 110 and prevent the housing 110 from detaching from the cover 120 when the inverter is suspended on the photovoltaic frame, thus preventing damage to the electrical components inside the housing 110.
[0050] In other embodiments, the number of anti-detachment parts 142 may be one or three, and the number of anti-detachment parts 142 may be adjusted according to the actual situation.
[0051] It should be noted that if there are two anti-detachment parts 142, the extrusion part 140 can be barbed, conical, or irregularly circular, etc. If there is only one anti-detachment part, the extrusion part 140 can be semi-barbed, semi-conical, or irregularly semi-circular, etc.
[0052] Further, please refer to Figures 1-4A guide slope 131 is provided at the opening of the glue storage tank 130 to guide the glue into the glue storage tank 130. Specifically, the guide slope 131 is provided on the side of the glue storage tank 130 near the receiving cavity 111, so that when the extruder 140 squeezes the glue in the glue storage tank 130, some of the overflowing glue will flow back to the bottom of the glue storage tank 130 under the guidance of the guide slope 131, thereby preventing glue from overflowing into the receiving cavity 111 and affecting the electrical components in the receiving cavity 111.
[0053] Please refer to Figures 1-4 as well as Figures 6-8 , Figure 6 This is a schematic diagram of the structure of the glue storage tank 130 in the first direction provided in this embodiment; Figure 7 This is a schematic diagram of the structure of the glue storage tank 130 in the second direction provided in this embodiment; Figure 8 This is a schematic diagram of the extrusion member 140 provided in this embodiment. In the figure, the X direction is the first direction, the Y direction is the second direction, and the first and second directions are perpendicular.
[0054] In this embodiment, the glue storage tank 130 extends along a first direction or a second direction, and the length of the extruder 140 in the first direction or the second direction is less than the extension length of the glue storage tank 130.
[0055] Specifically, in this embodiment, the glue storage tank 130 includes two first glue storage sections 132 and two second glue storage sections 133. The first glue storage sections 132 extend along a first direction; the second glue storage sections 133 extend along a second direction; the first glue storage sections 132 and the second glue storage sections 133 are in communication; the first glue storage section 132 accommodates a first extruder 140; the second glue storage section 133 accommodates a second extruder 140; the length of the first extruder 140 in the first direction is less than the extension length of the first glue storage section 132; the length of the second extruder 140 in the second direction is less than the extension length of the first glue storage section 132; the first direction is perpendicular to the second direction.
[0056] Both ends of the first glue storage section 132 and the second glue storage section 133 are open, so that the two first glue storage sections 132 and the two second glue storage sections 133 are interconnected in an alternating manner, and the glue storage tank 130 is an annular groove. It can also be understood that each side wall of the housing 110 is provided with a glue storage tank 130.
[0057] This results in the gaps between the four side walls of the housing 110 and the cover 120 being filled by the gel layer 150, thereby improving the sealing performance of the inverter housing 100.
[0058] In this embodiment, both the first glue storage section 132 and the second glue storage section 133 are provided with an extruder 140. In other embodiments, the first glue storage section 132 and the second glue storage section 133 may also be provided with multiple extruders 140.
[0059] Please refer to Figure 9 , Figure 9 This is a schematic diagram of the extruder 140 provided for other embodiments. In other embodiments, a plurality of extruders 140 housed in a first glue reservoir 132 are spaced apart along a first direction; a plurality of extruders 140 housed in a second glue reservoir 133 are spaced apart along a second direction.
[0060] Specifically, in this embodiment, the length of the extruder 140 is greater than that in other embodiments, thereby adjusting the contact area between the extruder 140 and the adhesive to regulate the extrusion effect of the extruder 140 on the adhesive. Operators can adjust the number and length of the extruders 140 according to actual conditions.
[0061] In other embodiments, the number of the first glue reservoir 132 and the second glue reservoir 133 can also be adjusted adaptively according to the actual situation.
[0062] Specifically, if there are two first glue storage sections 132 or two second glue storage sections 133, and one other section, it can be understood that the three side walls of the housing 110 are provided with glue storage grooves 130. If there is one first glue storage section 132 and one second glue storage section 133, it can be understood that two adjacent side walls of the housing 110 are provided with glue storage grooves 130. If only two first glue storage sections 132 or two second glue storage sections 133 are provided, it can be understood that two opposite side walls of the housing 110 are provided with glue storage grooves 130. If only one first glue storage section 132 or one second glue storage section 133 is provided, it can be understood that one side wall of the housing 110 is provided with a glue storage groove 130.
[0063] In summary, the inverter housing 100 provided in this embodiment includes a housing 110 and a cover 120; the housing 110 is provided with an accommodating cavity 111 and an opening 112 that are interconnected; the accommodating cavity 111 is used to accommodate electrical components; the opening 112 is used for the electrical components to pass through; the cover 120 is used to open or close the opening 112; one end face of the opening 112 and the end face of the cover 120 are provided with a glue storage tank 130, and the other end face is provided with at least one extrusion member 140; the extrusion member 140 is located in the glue storage tank 130; the glue storage tank 130 accommodates a gel layer 150, and the gel layer 150 wraps the extrusion member 140; the gel layer 150 is used to fill the gap between the housing 110 and the cover 120.
[0064] In this embodiment, glue is filled into the glue storage tank 130, and during the closing process of the housing 110 and the cover 120, the glue is squeezed by the extruder 140, causing the glue to overflow into the gap between the housing 110 and the cover 120. After the glue solidifies to form a gel layer 150, the gap between the housing 110 and the cover 120 is filled by the gel layer 150, preventing external impurities from entering through the gap between the housing 110 and the cover 120, thereby achieving a seal and preventing external impurities from affecting the electrical components in the accommodating cavity 111, thus improving the protection effect on the electrical components.
[0065] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto.
