Description

Technical Field

[0001] This invention relates to inverter mounting structures, and more specifically, to an inverter mounting structure that improves assembly convenience and durability and simplifies the structure of the inverter. Background Technology

[0002] As the application of electric motors expands, the use of inverters is also increasing. These inverters are used by integrating with walls or housings, and various devices can be selectively installed onto them as needed.

[0003] These additional installations are called optional accessories, which include, for example, cable holders for securing cables electrically connected to the inverter, so that the cables will not come off or break due to their own weight or other external forces.

[0004] Figures 1 to 3 This is a diagram showing an existing inverter and optional accessories installed on the inverter.

[0005] like Figure 1 and Figure 2 As shown, the existing inverter 10 is composed of a heat sink 20 for heat dissipation on one side and optional accessories 30 such as cable fixing boxes installed on any side of the outside.

[0006] That is, the inverter 10 can be installed by combining the heat sink 20 with the casing or wall, and can be grounded through the heat sink 20.

[0007] In addition, the optional accessory 30 can be combined with the inverter 10 by fastening it to a plurality of positions.

[0008] At this time, as Figure 3 As shown, the optional accessory 30 is configured such that a metal strip 32 extending from a portion thereof is inserted into the inside of the inverter 10 and combined with the inverter 10, and the inserted portion is electrically connected to the grounding path 12 inside the inverter 10 to maintain grounding.

[0009] In addition, this grounding path 12 is also electrically connected to the heat sink 20 made of metal material, so that grounding can be achieved through the contact between the heat sink 20 and the casing or wall.

[0010] The mounting structure of the optional accessory 30 installed on this existing inverter 10 has the following problems.

[0011] First, since the optional accessory 30 is combined with the inverter 10, the load acting on the optional accessory 30 is applied to the inverter 10. Therefore, the inverter 10 needs to be made with high rigidity, which leads to an increase in the manufacturing cost and weight of the inverter 10.

[0012] Secondly, the heat sink 20 attached to the inverter 10 is a structure that is combined with the casing or wall. In addition to its original heat dissipation function, the heat sink 20 also serves to fix the inverter 10. Therefore, it needs to be made to bear the load and thus needs to be manufactured with high rigidity, which leads to increased manufacturing costs and weight.

[0013] Third, since the optional accessory 30 is combined with the inverter 10, a grounding path 12 needs to be formed inside the inverter 10 for grounding. This grounding path 12 originally needed to be made to be exposed to the outside to be combined with the heat sink 20 and the optional accessory 30. However, since it is necessary to form a grounding path inside the inverter 10, the design and manufacture of the inverter 10 become difficult. Furthermore, under certain setup conditions, the presence of this exposed grounding path 12 may also cause adverse problems. Summary of the Invention

[0014] The problem that the invention aims to solve

[0015] The present invention addresses the problems described above, and its objective is to provide an inverter mounting structure that is easy to install, has a robust structure, and simplifies the manufacturing and design of inverters.

[0016] The subject matter of this invention is not limited to the subject matter mentioned above, and those skilled in the art can clearly understand other subject matters not mentioned from the following description.

[0017] Technical solutions to the problem

[0018] To address the aforementioned issues, according to one aspect of the present invention, an inverter mounting structure is provided, comprising: a bracket fixed to a housing or wall, wherein an inverter housing space is formed inside the bracket to accommodate an inverter for mounting; and an optional housing attached to the outside of the bracket.

[0019] The bracket may include: a first surface, formed facing the housing or wall, to which the inverter is attached; a second surface, extending from the first surface in a direction perpendicular to the housing or wall, and formed parallel to each other from both sides of the first surface in a manner facing each other, to form the sides of the inverter receiving space; and a fixing portion, extending bent from the first surface toward the housing or wall, and formed with fixing holes for fixing to the housing or wall; one end of each of the second surfaces may be bent toward each other to form a flange.

[0020] The optional housing can be installed by engaging with the flange.

[0021] The optional housing may have a grounding section, and the grounding wire installed at the grounding terminal of the inverter is electrically connected to the grounding.

[0022] The bracket and optional housing may be formed of a conductive material to ground the inverter.

[0023] The second surface can be configured to expose a portion of the side surface of the inverter, and can have at least one or more vent holes.

[0024] The optional housing may have a plurality of through holes for connecting cables electrically connected to the inverter.

[0025] In addition, according to another aspect of the present invention, an inverter mounting structure is provided, comprising: a bracket fixed to a housing or wall in a grounded state, wherein an inverter housing space is formed inside the bracket to accommodate an inverter for mounting; an optional housing attached to the outside of the inverter housing space of the bracket and configured to be electrically connected to the bracket; and a grounding portion disposed in the optional housing such that a grounding wire mounted on the grounding terminal of the inverter is electrically connected to the grounding portion.

[0026] Invention Effects

[0027] The inverter mounting structure according to the present invention has the following effects.

[0028] In the prior art, it is necessary to design grounding paths for metal structures configured for grounding in both the parts where the inverter contacts the optional housing and the parts where the inverter contacts the housing. However, with the inverter mounting structure according to the present invention, since grounding can usually be achieved through the grounding terminals of all inverters, there is no need to form additional grounding paths, thereby simplifying the design and reducing manufacturing costs.

[0029] The effects of the present invention are not limited to those mentioned above, and those skilled in the art can clearly understand other effects not mentioned from the description of the claims. Attached Figure Description

[0038] In the following description, various embodiments will be illustrated in more detail with reference to the accompanying drawings. Embodiments of the present invention can be varied. Specific embodiments may be depicted in the drawings and may be described in detail in the detailed description. However, the specific embodiments disclosed in the drawings are merely to facilitate understanding of various embodiments. Therefore, the technical concept of the present invention is not limited to the specific embodiments disclosed in the drawings and should be understood to include all equivalents or substitutes within the scope of the present invention.

[0039] Although terms including ordinal numbers such as first and second may be used when describing multiple constituent elements, these constituent elements are not limited by the terms described above. The terms described above are used only to distinguish one constituent element from another.

[0040] In embodiments of the present invention, it should be understood that terms such as "comprising" or "having" are intended to indicate the presence of the features, numbers, steps, actions, constituent elements, components, or combinations thereof described in the embodiments of the present invention, rather than precluding the existence or additional possibility of one or more other features, numbers, steps, actions, constituent elements, components, or combinations thereof. When referring to one constituent element as "connected" or "linked" to another constituent element, it should be understood that it may be directly connected or linked to that other constituent element, but other constituent elements may also exist between them. Conversely, when referring to one constituent element as "directly connected" or "directly linked" to another constituent element, it should be understood that no other constituent elements exist between them.

[0041] On the other hand, the “module” or “part” of the relevant constituent elements used in the embodiments of the present invention performs at least one function or action. Furthermore, a “module” or “part” can perform a function or action through hardware, software, or a combination of hardware and software. Additionally, a plurality of “modules” or “parts” other than those that need to be executed in specific hardware or in at least one processor can also be integrated into at least one module. Unless the context clearly specifies otherwise, singular expressions include plural expressions.

[0042] Furthermore, when describing embodiments of the present invention, if it is determined that a detailed description of a relevant known function or structure may unnecessarily obscure the spirit of the present invention, its detailed description will be abbreviated or omitted.

[0043] The following will describe an embodiment of the inverter mounting structure of the present invention.

[0044] like Figures 4 to 6 As shown, the inverter mounting structure in this embodiment may include a bracket 110 and an optional housing 120.

[0045] The bracket 110 can be fixed to the casing or wall, and can form an inverter housing space inside for the inverter 100 to be connected and accommodated. At this time, the casing and wall can be grounded to the ground.

[0046] Additionally, the optional housing 120 is a housing for accommodating or mounting various optional devices additionally attached to the inverter 100, which can be combined with the outside of the bracket 110.

[0047] In this embodiment, as the optional housing 120, an example of using a cable fixing box will be described. The cable fixing box fixes cables 40 and the like that that are electrically connected to the inverter 100 in a manner that enables them to send and receive power or signals, so that the cables 40 will not fall off or break due to the load of the cables 40 themselves or other external forces.

[0048] Therefore, the optional housing 120 may have a plurality of through holes 122 for connecting and securing the cable 40 electrically connected to the inverter 100. Cable fixing nuts or similar devices are fitted into the through holes 122 to secure the cable 40 to the optional housing 120. That is, since the cable 40 is secured to the optional housing 120, the load or external force applied to the cable 40 can act on the optional housing 120 rather than the portion where the inverter connects to the cable 40, thereby strengthening the cable's securing force.

[0049] Of course, the optional housing 120 is not limited to this, and optional housing 120 may also be installed for other functions and destinations.

[0050] That is, since the optional housing 120 is fixed to the bracket 110 instead of the inverter 100, the load applied to the optional housing 120 can be directly transferred to the bracket 110 instead of the inverter 100, thereby reducing the force applied to the inverter 100. Therefore, the inverter 100 does not need to be manufactured to be too strong, especially in the case of a heat sink, which can be simplified because it is not subject to load, thereby further achieving weight reduction.

[0051] The bracket 110 may include a first surface 111, a second surface 112, a fixing part 113, and a flange part 114.

[0052] The first surface 111 may be formed facing the housing or wall surface on which the bracket 110 is fixed, and the inverter 100 may be coupled to the first surface 111. In this case, the first surface 111 may be flat, but is not necessarily limited to this. One or more threaded holes or the like may be formed on the first surface 111 for coupling the inverter 100.

[0053] The second surface 112 may be formed to extend from both sides of the first surface 111 in a direction perpendicular to the housing or wall, thereby forming an inverter housing space together with the first surface 111 for accommodating the inverter 100. A pair of second surfaces 112 may extend parallel to each other.

[0054] At this time, the second surface 112 can be configured to expose at least a portion of the side of the inverter 100 without covering it entirely. This is to facilitate gripping the inverter 100 when placing it into or removing it from the inverter housing.

[0055] On the other hand, the fixing part 113 can be bent and extended from the edge of the first surface 111 toward the housing or wall, and can form a fixing hole 115 to fix it to the housing or wall through the fixing hole 115. Of course, if necessary, the fixing part 113 can also extend from the edge of the first surface 111 in a planar manner instead of bending, and the fixing hole 115 can be formed on its edge.

[0056] In addition, the fixing components for fixing the bracket 110 through the fixing hole 115 can be screws or bolts, but are not necessarily limited to these; other fixing components such as rivets can also be used.

[0057] That is, the inverter 100 is fixed to the first surface 111, and the first surface 111 on which the inverter 100 is fixed is fixed to the casing or wall by means of the fixing part 113 formed on the first surface 111.

[0058] At this time, a plurality of vent holes 116 for heat dissipation can be formed on the first surface 111 and the second surface 112.

[0059] In addition, the surface opposite to the first surface 111 can be opened. Typically, various operating switches or I / O panel covers are located on the surface of the inverter facing the surface opposite to the first surface 111, so the corresponding surface can be opened to avoid interference with these.

[0060] Additionally, one end of the second surface 112 can be bent in a direction facing each other to form a flange 114, and the optional housing 120 can be fixed to the bracket 110 by engaging with the flange 114. That is, the optional housing 120 can be fastened to the flange 114 by means of fixing members such as screws, bolts and nuts.

[0061] On the other hand, the bracket 110 and the optional housing 120 may be formed of conductive materials such as metal to enable grounding of the cables installed to the inverter 100 and the optional housing 120.

[0062] In addition, such as Figure 7 As shown, a grounding portion 130 may be provided in the optional housing 120 to ground the inverter 100. A grounding wire 132 connected to the grounding terminal of the inverter may be connected to the grounding portion 130. In this case, the connection between the grounding wire 132 and the grounding portion 130 may be achieved using a conductive bolt or the like.

[0063] Therefore, the grounding wire 132 connected to the grounding terminal of the inverter 100 is connected to the grounding portion 130 of the optional housing 120, and the optional housing 120 is in contact with the bracket 110 which is directly electrically connected to the housing or wall. Thus, the inverter 100 and the optional housing 120 can be grounded even without forming an additional grounding path 12 in the inverter 100 or without exposing the grounding path 12 to the outside.

[0064] That is, since the inverter 100 must have a grounding terminal inside, in this embodiment, the need to form an additional grounding path 12 can be eliminated by using the necessary grounding terminal for grounding.

[0065] Therefore, the design of inverter 100 can be further simplified, making its design and manufacture easier. Furthermore, the variety and number of components required to manufacture inverter 100 can be reduced accordingly, thereby reducing not only component costs but also labor hours, and thus the effect of reducing manufacturing costs can be expected.

[0066] As described above, preferred embodiments of the invention have been presented, and it will be apparent to those skilled in the art that, in addition to the embodiments described above, the invention may be embodied in other specific forms without departing from its purpose or scope. Therefore, the above embodiments should be considered exemplary rather than restrictive, and thus, the invention is not limited to the foregoing description, but can be modified within the scope of the appended claims and their equivalents.
