Description

Technical Field

[0001] This utility model relates to the field of inverter technology, specifically to an inverter enclosure. Background Technology

[0002] Currently, some inverter enclosures on the market often use welding at the joints of sheet metal parts. This involves welding to fix the bent sheet metal joints and connecting the structural seams of the enclosure. After welding, the enclosure needs to be trimmed of weld marks and polished to maintain its appearance. Because most welding methods use localized heating, the welded parts inevitably experience stress and deformation within the structure, affecting its load-bearing capacity, machining accuracy, and dimensional stability.

[0003] Because most welding methods employ localized heating, the welded components inevitably experience stress and deformation within the structure, affecting its load-bearing capacity, machining accuracy, and dimensional stability. Furthermore, stress concentration occurs at the weld-workpiece interface, and welding defects (such as cracks, porosity, slag inclusions, incomplete penetration, and lack of fusion) can contribute to brittle fracture. Sheet metal welding often requires pre-fixture fixation. The process demands high levels of skill from both welding equipment and personnel. Some advanced welding equipment is expensive, representing a significant expense for businesses. The welding process also generates high temperatures, intense light, and some toxic gases, which can be harmful to human health. Utility Model Content

[0029] like Figures 1-5 As shown, an inverter enclosure of this utility model includes a bottom shell 10 and a front cover 20 adapted to the bottom shell 10. The bottom shell 10 serves as the main body of the inverter enclosure, and the front cover 20 is used to close the opening of the bottom shell 10, protecting the internal components of the inverter. The bottom shell 10 includes a bottom plate 11 and an outer shell 12 disposed on the bottom plate 11. The outer shell 12 includes a first side wall 121 and a second side wall 122 disposed opposite to each other. The first side wall 121 and the second side wall 122 are interconnected to form the outer shell 12. The outer shell 12 and the bottom plate 11 define a receiving space for accommodating the internal components of the inverter.

[0030] The first sidewall 121 includes a straight plate 1211, rounded corner edges 1212 on both sides of the straight plate 1211, and bent edges 1213 connected to the rounded corner edges 1212. In this invention, the rounded corner edge 1212 refers to the arc structure at the corner of the enclosure, and the bent edge 1213 refers to the step formed with the rounded corner edge 1212, forming a sheet metal splicing seam, so that the second sidewall 122 overlaps on the bent edge 1213 and is connected by the first fixing member 123; furthermore, there is a sheet metal splicing seam between the bent edge 1213 and the second sidewall 122. The rounded corner edges 1212 are provided on both sides of the first sidewall 121 to increase the strength and aesthetics of the enclosure. This inverter enclosure helps to reduce enclosure deformation, ensures dimensional stability, and reduces reliance on personnel skills, welding equipment, and manufacturing tooling. It can be assembled automatically, with simple processing steps, high production efficiency, and good economic value.

[0031] In some specific embodiments, the first fixing member 123 is a rivet. The rivet passes sequentially through the through holes on the bent edge 1213 and the second side wall 122. Through the riveting process, the bent edge 1213 and the second side wall 122 are fixedly connected, thereby sealing the sheet metal splice seam at the rounded corner edge 1212. Using the riveting process reduces the investment in welding equipment and tooling, ensures structural strength, reduces costs, improves production efficiency, and facilitates the assembly and disassembly of the housing. Preferably, the top surface of the rivet is flush with the surface of the outer shell 12, with no protruding structure, resulting in an aesthetically pleasing appearance.

[0032] In one specific embodiment, such as Figures 6-7 As shown, the bottom shell 10 also includes a bracket 13 with a receiving space and a dust cover 14. The first sidewall 121 and / or the second sidewall 122 have pre-reserved mounting positions for the bottom shell 10. The bracket 13 and the dust cover 14 are respectively provided with a first ventilation hole 131 and a second ventilation hole 141, forming a receiving cavity. The receiving cavity contains filter cotton 16 for filtering the air entering the enclosure. The dust cover 14 and the filter cotton 16 effectively prevent dust and other impurities from damaging the internal components of the inverter, improving the protection level of the enclosure. Simultaneously, the quick-disassembly design of the dust cover 14 and the bracket 13 facilitates user maintenance and cleaning of the inverter. The design of the first ventilation hole 131 and the second ventilation hole 141 is for heat dissipation, which is beneficial for air exchange.

[0033] In some specific embodiments, the bracket 13 includes a bracket body 132 with an internal receiving space and a folded edge 133 disposed on the outer edge of the bracket body 132. A first ventilation hole 131 is formed on the bottom of the bracket body 132. The bracket body 132 and the dust cover 14 define a receiving cavity. A through hole is formed on the folded edge 133. The bracket 13 is fixed to the outer shell 12 by a second fastener 136. Specifically, the second fastener 136 can be a rivet, which passes through the through hole of the folded edge and the through hole of the outer shell 12 to fix the bracket 13 to the outer shell 12. The riveting process reduces the investment in welding equipment and tooling, lowers costs, and improves production efficiency.

[0034] In a preferred embodiment, the bracket 13 is further provided with a positioning post 134, and the dust cover 14 is provided with a mounting hole that matches the positioning post 134. The dust cover 14 is fixed to the bracket 13 by a third fastener 143 through the mounting hole and the positioning post 134. The third fastener 143 can be a fastening screw, and the positioning post 134 can be a nut post. The fastening screw is connected to the nut post to complete the installation of the dust cover 14.

[0035] In a preferred embodiment, a positioning groove 135 is provided on the side wall of the bracket 13 and on either of the dust cover 14, and a positioning protrusion 142 is provided on the other at the corresponding position. The bracket 13 and the dust cover 14 are fixed by being inserted into the positioning protrusion 142 through the positioning groove 135, so as to realize the quick installation and removal of the dust cover 14.

[0036] In one specific embodiment, the inverter enclosure further includes a wall mount 30, which is connected to the base plate 11 and extends outward relative to the outer casing 12. The wall mount 30 has hanging holes for easy mounting of the inverter enclosure to a wall or other fixed structure. The outer contour of the wall mount 30 is an arc-shaped, M-like structure, which reduces product weight, enhances aesthetics, and improves strength and stability. The wall mount 30 is fixedly connected to the base casing 10 by rivets. The rivets can be made of aluminum, stainless steel, iron, etc. The rivet material can be adjusted according to strength, corrosion resistance, etc., reducing costs and improving adaptability to different application scenarios.

[0037] The inverter enclosure of this utility model has at least the following beneficial effects: By rationally designing the enclosure structure and dividing it into modular designs, which are then assembled using fasteners, unlike welded enclosures, this solution eliminates the need for post-weld grinding and slag removal. This helps reduce enclosure deformation, ensures dimensional stability, and reduces reliance on personnel skills, welding equipment, and manufacturing tooling. Automated assembly is possible, simplifying the processing steps, increasing production efficiency, and providing good economic value. The dustproof design of the dust cover 14 and filter cotton 16 allows for easy installation and disassembly, reducing dust and foreign objects from entering the enclosure and improving its protection level. The addition of a rounded shape to the wall mount 30 design reduces product weight while enhancing its aesthetics.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
