Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of inverter structure, in particular to an inverter box and a photovoltaic inverter. BACKGROUND

[0002] An inverter is an electronic device that converts direct current (DC) to alternating current (AC). It is widely used in many fields, including solar power generation systems, wind power generation systems, electric vehicle charging stations, etc. According to the application scenarios of inverters, different inverter products can be divided into photovoltaic inverters, energy storage inverters, etc.

[0003] With the popularization of inverter products, competition among various products is intensifying, and each product is pursuing the ultimate size and cost. Since inverter products need to be designed for waterproofing, the traditional cover plate waterproofing design is to fold the bottom frame outward by one turn and then fix the screws on the outer periphery and the front of the upper cover. However, the conventional design of cover plate sealing occupies a large space, which is invalid space, resulting in a significant reduction in the net space of the product box. SUMMARY

[0004] Therefore, in order to solve the problem that the conventional design of cover plate sealing occupies a large space, which is invalid space, resulting in a significant reduction in the net space of the product box, the present disclosure provides an inverter box and a photovoltaic inverter.

[0009] The inverter box of the present disclosure comprises a bottom frame, a sealing component and a cover plate. The sealing component is arranged on one frame of the bottom frame, and the frame is sealed by the cover plate. The sealing box formed in this way does not need to be folded on the bottom frame, greatly improving the space utilization rate of the inverter and effectively reducing the cost.

[0010] As one of the optional embodiments, it further comprises:

[0011] a fixing component for fixing the cover plate on the bottom frame.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0034] Unless otherwise defined, the technical or scientific terms used in this disclosure shall have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms “first,” “second,” and similar terms used in this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components.

Terms such as “connected” or “linked” are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as “upper,” “lower,” “left,” and “right” are used only to indicate relative positional relationships, and these relative positional relationships may change accordingly when the absolute position of the described objects changes.

[0035] To keep the following description of the embodiments of this disclosure clear and concise, detailed descriptions of some known functions and components have been omitted.

[0036] This disclosure provides an inverter enclosure.

[0037] Figure 1 This is a schematic diagram of an inverter housing structure according to a disclosed embodiment, as shown below. Figure 1 As shown, an inverter housing according to a disclosed embodiment includes:

[0038] Base frame 100;

[0039] A sealing component 101 is disposed on one side of the bottom frame 100;

[0040] Cover plate 102 is used to cover the frame.

[0041] like Figure 1As shown, the bottom frame 100 is a semi-enclosed box, generally a sealed cubic box. One side of the box is designed to be open to cover the cover plate 102, and the edge of the open side is the frame.

[0042] The cover plate 102 covers the frame, that is, it covers one side of the opening design of the bottom frame 100. At the same time, the sealing component 101 is used to seal the gap between the cover plate 102 and the frame, forming an integrally sealed inverter enclosure.

[0043] As one embodiment, the inverter enclosure of a disclosed embodiment further includes:

[0044] A fixing component is used to fix the cover plate 102 to the bottom frame 100.

[0045] The fixing component is used to fix the cover plate 102 to the bottom frame 100, indirectly fixing the sealing component 101 and maintaining the stability of the inverter enclosure sealing space.

[0046] The fixing components can be fixed by snap-fit, plug-in, or screw 104. By selecting a suitable fixing structure, the connection stability between the cover plate 102 and the base frame 100 is maintained.

[0047] As one embodiment, the fixing component includes:

[0048] The first connecting part is provided in the bottom frame 100;

[0049] The second connecting portion is provided on the cover plate 102;

[0050] A connecting component for connecting the first connecting part and the second connecting part.

[0051] The connecting component connects the first connecting part and the second connecting part, indirectly connecting and fixing the bottom frame 100 and the cover plate 102. At the same time, since the sealing component 101 is set on the frame, fixing the bottom frame 100 and the cover plate 102 also fixes the sealing component 101 between them.

[0052] As a preferred embodiment, such as Figure 1 As shown, the fixing component adopts a screw 104 fixing structure, and the corresponding first connecting part and second connecting part are screw holes 103, and the connecting component is a screw 104.

[0053] Screw 104 passes through the first connecting part and the second connecting part to complete the screw 104 locking, and fixes the cover plate 102 to the bottom frame 100 by screw 104.

[0054] As a preferred embodiment, countersunk screws 104 are selected to avoid the impact of screws 104 on the shape of the inverter enclosure and improve aesthetics.

[0055] As one embodiment, the fixing component further includes:

[0056] A connecting seal is disposed between the first connecting part and the second connecting part.

[0057] By connecting the sealing element, the first connection part and the second connection part are sealed, ensuring the overall airtightness of the inverter enclosure.

[0058] As a preferred embodiment, such as Figure 1 As shown, the connecting seal is a gasket 105, such as a rubber gasket 105.

[0059] As one example, such as Figure 1 As shown, the cover plate 102 includes:

[0060] Cover 106;

[0061] The sides 107 are provided around the faceplate 106.

[0062] Preferably, the second connecting part is provided on the side 107, so the frame of the bottom frame 100 does not need to be folded, thus ensuring the utilization rate of the internal space of the inverter box.

[0063] Figure 2 This is a side view of the inverter enclosure, as shown. Figure 2 As shown, the sealing component 101 is a sealing strip. Preferably, the angled space formed by the faceplate 106 and the side 107 of the cover plate 102 can limit the sealing strip and improve the sealing effect. The gasket 105 serves as a sealing structure between the screw 104 and the screw hole 103, and also cushions the cover plate 102.

[0064] The inverter enclosure according to any of the above embodiments of this disclosure includes a base frame 100, a sealing component 101, and a cover plate 102. The sealing component 101 is disposed on one side of the base frame 100, and the cover plate 102 covers this side to form a sealed enclosure. This sealed enclosure design eliminates the need for folding the base frame 100, greatly improving the space utilization of the inverter and effectively reducing costs.

[0065] Based on the inverter enclosure, this disclosure also provides a photovoltaic inverter, including:

[0066] Inverter housing of any of the above embodiments;

[0067] The inverter circuit is installed inside the inverter enclosure.

[0068] The aforementioned photovoltaic inverter includes an inverter enclosure and an inverter circuit housed within the enclosure. The inverter enclosure comprises a bottom frame, a sealing component, and a cover plate. The sealing component is located on one side of the bottom frame, and the cover plate covers this side to form a sealed enclosure. This sealed enclosure design eliminates the need for folding the bottom frame, significantly improving the inverter's space utilization and effectively reducing costs.
