[0045] Figure 1 is a schematic structural diagram of an air conditioner indoor unit according to an embodiment of the utility model, such as Figure 1 As shown, and refer to Figure 2-9 The embodiment of the utility model provides a support assembly 100 of an air conditioner indoor unit, which is used to fix a base 400 and a rear panel 500 of the air conditioner indoor unit. The support assembly 100 includes a crossbeam 200 and a support column 300 .

[0046] The crossbeam 200 is arranged horizontally, and both left and right ends are fixedly connected to the rear panel 500. The upper end of the support column 300 is fixedly connected to the crossbeam 200, and the lower end of the support column 300 is fixedly connected to the base 400.

[0047] The crossbeam 200 and the support column 300 are both sheet metal parts. The crossbeam 200 is provided with a first connection structure 210, which includes a first connection hole 211 and a limit hole 212. The upper end of the support column 300 is provided with a second connection hole 320 and a limit plate 340 corresponding to the first connection hole 211 and the limit hole 212, and the limit plate 340 is inserted into the limit hole 212.

[0048] The indoor air conditioner can be a split type indoor cabinet air conditioner or an integrated mobile indoor cabinet air conditioner. The cabinet air conditioner usually has a large height-to-width ratio, resulting in poor stability of the whole machine.

[0049] The rear panel 500 is usually made of plastic and is processed by injection molding. Due to material limitations, the structural strength of the rear panel 500 is usually weaker than that of metal materials such as steel and iron. Although the stability of the whole machine can be improved to a certain extent by significantly increasing the thickness of the rear panel 500 and the width and thickness of the reinforcing ribs, it will lead to a significant increase in cost and weight of the whole machine.

[0050] In this embodiment, the support assembly 100 is provided to strengthen the connection strength between the base 400 and the rear panel 500 and to strengthen the structural strength of the rear panel 500 itself, thereby improving the stability of the entire device.

[0051] Specifically, the support assembly 100 includes a crossbeam 200 and a support column 300. The crossbeam 200 is arranged at a preset height above the base 400. The two ends of the crossbeam 200 can be directly fixedly connected to the left and right ends of the rear panel 500, or can be indirectly fixedly connected to the left and right ends of the rear panel 500. For example, the left and right ends of the rear panel 500 are respectively fixedly connected to a frame column, and the two ends of the crossbeam 200 are respectively fixedly connected to two frame columns. The connection method of the crossbeam 200 and the rear panel 500 or the frame column can be fastener connection, socket connection, clamping, etc., which is not limited here.

[0052] The crossbeam 200 can be a sheet metal part with a small weight and good structural strength. The rear panel 500 is usually a U-shaped or semi-cylindrical shell with an opening facing forward. The two ends of the crossbeam 200 are fixedly connected to the left and right ends of the rear panel 500, so that the crossbeam 200 can support the rear panel 500, improve the bending strength of the rear panel 500, and thus improve the stability of the whole machine to a certain extent.

[0053] The support column 300 can be a sheet metal part with a small weight and good structural strength, and is used to form a firm connection between the crossbeam 200 and the base 400. Specifically, the crossbeam 200 is provided with a first connection structure 210, and the upper end of the support column 300 is provided with a corresponding second connection hole 320 and a stop plate 340, and the first connection hole 211 and the second connection hole 320 can be fixedly connected by fasteners. The lower end of the support column 300 can be fixedly connected to the base 400 by fasteners, plug-in connection, clamping, etc.

[0054] The first connection hole 211 can be set at the front side of the crossbeam 200, or at the lower side or upper side of the crossbeam 200. The limiting hole 212 can be set at the same surface of the first connection hole 211, or at different surfaces. It should be understood that when the first connection hole 211 and the second connection hole 320 can be fixedly connected by fasteners, there may be a rotational freedom between the support column 300 and the crossbeam 200 in the axial direction of the connection hole. By setting the limiting hole 212 and the limiting plate 340, when the limiting plate 340 is inserted into the limiting hole 212, the support column 300 can be prevented from rotating relative to the crossbeam 200. In other words, the first connection hole 211 and the second connection hole 320, the limiting hole 212 and the limiting plate 340 work together to form a firm connection between the support column 300 and the crossbeam 200, so that the support assembly 100 itself has a good structural strength, thereby strengthening the connection strength between the rear panel 500 and the base 400, and achieving the effect of improving the stability of the air conditioner indoor unit.

[0055] On the other hand, since the cross beam 200 and the support column 300 are both sheet metal parts, such as thin iron plates, the strength of their materials is greater than the strength of the material of the rear panel 500, and their material cost is lower than that of the rear panel 500. Compared with the solution of greatly increasing the amount of material used for the rear panel 500 and reinforcing the ribs of the rear panel 500 in the prior art, the present application can greatly improve the stability of the air conditioner indoor unit without greatly increasing the weight and cost of the whole unit.

[0056] In some embodiments of the support assembly of the present invention, Figure 3 As shown, the support column 300 is arranged to be inclined forward and backward, and the angle α between the length direction of the support column 300 and the horizontal plane is 95-115 degrees.

[0057] The support column 300 is tilted forward and backward, and the lower end of the support column 300 is in front of the upper end. The geometric stability of the triangle can be used to further improve the support strength of the support assembly 100 to the rear panel 500 and the base 400, preventing the air conditioner indoor unit from shaking forward and backward.

[0058] In this embodiment, the angle α between the length direction of the support column 300 and the horizontal plane is 95-115 degrees. It can also be said that the angle between the length direction of the support column 300 and the bottom surface of the base 400 is 95-115 degrees. The smaller the angle between the support column 300 and the horizontal plane, the better the supporting effect on the lower part of the rear panel 500 in the front-to-back direction. However, for the whole machine, the structural strength of the upper part of the rear panel 500 relative to the base 400 has a greater impact on stability. The larger the angle between the support column 300 and the horizontal plane, or the closer it is to 90 degrees, the higher the upper end of the support column 300, that is, the rear panel 500 is supported at a higher position, which more effectively improves the structural strength of the upper part of the rear panel 500 relative to the base 400. 95-115 degrees is a better range considering all aspects.

[0059] Preferably, the angle α between the length direction of the support column 300 and the bottom surface of the base 400 is 105 degrees.

[0060] In some embodiments of the support assembly of the present invention, Figure 4-6 As shown, the crossbeam 200 includes a first front side plate 220 which is vertically arranged and extends left and right, and the first connecting hole 211 and the limiting hole 212 are both located on the first front side plate 220 .

[0061] The support column 300 includes a column body 310 and a first upper folding plate 350 formed by bending upward from the upper end of the column body 310. The back of the first upper folding plate 350 is attached to the front of the first front side plate 220, and the second connection hole 320 is located on the first upper folding plate 350.

[0062] One transverse end edge of the first upper folding plate 350 is bent backward to form a limiting plate 340 .

[0063] The cross beam 200 and the support column 300 are both sheet metal parts, and can be formed by bending an iron plate with a thickness of 1-2 mm.

[0064] In this embodiment, the first connection hole 211 and the limiting hole 212 are both located in the first front side plate 220, which is convenient for installation. The front side of the air conditioner indoor unit has a large operating space, and during production and maintenance, after the front panel of the air conditioner indoor unit is disassembled, the support column 300 can be easily disassembled and assembled on the beam 200 from the front side.

[0065] On the other hand, during installation, the limiting plate 340 is aligned with the corresponding limiting hole 212 and inserted therein, and the second connecting hole 320 is automatically aligned with the first connecting hole 211, which can further improve the installation efficiency.

[0066] On the other hand, when the first connecting hole 211 and the limiting hole 212 are in the same plane, the first connecting hole 211 and the second connecting hole 320, the limiting hole 212 and the limiting plate 340 work together to make the supporting assembly 100 have better structural strength in the left and right directions, thereby strengthening the connection between the rear panel 500 and the base 400 in the left and right directions, thereby improving the stability of the whole machine.

[0067] In some embodiments of the support assembly of the present invention, Figure 6-7 As shown, the transverse end edges of the first upper folding plate 350 are respectively bent backward to form two limiting plates 340 .

[0068] The first connection structure 210 may be provided with two limiting holes 212, which are located on both lateral sides of the first connection hole 211. By providing the limiting holes 212 on both lateral sides of the first connection hole 211, the two limiting plates 340 on both lateral sides of the second connection hole 320 are limited, which can further improve the firmness of the connection between the support column 300 and the crossbeam 200, thereby improving the structural strength between the rear panel 500 and the base 400.

[0069] In some embodiments of the support assembly of the present invention, Figure 4-6 As shown, the cross beam 200 includes a first front side plate 220 vertically arranged and extending left and right, a lower side plate 230 formed by flanged backward from the lower edge of the first front side plate 220, and a first sheet metal hem 240 formed by flanged downward from the rear edge of the lower side plate 230.

[0070] The support column 300 includes a column body 310, and the column body 310 includes a second front side plate 312 and two side folding plates 313 formed by turning the left and right edges of the second front side plate 312 backward. The first upper folding plate 350 is fixedly connected to the second front side plate 312. The upper edges of the two side folding plates 313 are fitted or gap-fitted with the lower side plate 230, and the rear edges of the two side folding plates 313 are fitted or gap-fitted with the first sheet metal hem 240.

[0071] In this embodiment, the cross-sections of the cross beam 200 and the support column 300 are both roughly C-shaped to improve the bending strength in the length direction. On the other hand, by cleverly designing the shapes and positions of the lower side plate 230 and the side folding plate 313, the upper edge of the side folding plate 313 is perpendicular to the lower side plate 230, and the upper edge of the side folding plate 313 is in contact with or has a clearance fit with the lower surface of the lower side plate 230. When the support column 300 is fixedly connected to the cross beam 200, the upper edge of the side folding plate 313 and the lower side plate 230 can support each other, thereby improving the firmness of the connection between the support column 300 and the cross beam 200.

[0072] In this embodiment, the first sheet metal frill 240 can improve the structural strength of the cross beam 200 and prevent the burrs on the edge of the cross beam 200 from being exposed, thereby avoiding scratches on people. On the other hand, by cleverly designing the shape and position of the first sheet metal frill 240 and the side fold plate 313, the rear edge of the side fold plate 313 is perpendicular to the first sheet metal frill 240, and the rear edge of the side fold plate 313 is in contact with or has a clearance fit with the front surface of the first sheet metal frill 240. When the support column 300 is fixedly connected to the cross beam 200, the rear edge of the side fold plate 313 and the first sheet metal frill 240 can support each other, thereby improving the firmness of the connection between the support column 300 and the cross beam 200.

[0073] In some embodiments of the support assembly of the present invention, Figure 6-7 As shown, the second front side plate 312 is provided with a reinforcing rib 315 extending along the length direction thereof.

[0074] The reinforcing rib 315 may protrude forward or backward, which is not limited here. The reinforcing rib 315 may improve the bending strength of the support column 300 along the length direction.

[0075] In some embodiments of the support assembly of the present invention, Figure 6-7 As shown, the rear end of the side fold plate 313 is provided with a second sheet metal frill 314. The second sheet metal frill 314 can improve the structural strength of the support column 300 and prevent the burrs on the edge of the support column 300 from being exposed to avoid scratching people.

[0076] In some embodiments of the support assembly of the present invention, Figure 6-7 As shown, the support column 300 includes a column body 310 and a first lower folding plate 360 ​​formed by bending forward from the lower end of the column body 310 , and the first lower folding plate 360 ​​is arranged horizontally. A third connecting hole 330 is arranged on the first lower folding plate 360 ​​.

[0077] The base 400 is provided with a second connection structure 420 , which includes a first support surface 421 in contact with the bottom surface of the first lower folding plate 360 ​​, and a fourth connection hole 424 located in the first support surface 421 and corresponding to the third connection hole 330 .

[0078] In this embodiment, the first lower folding plate 360 ​​is in surface contact with the first supporting surface 421 on the base 400 , and the support column 300 and the base 400 are fixedly connected by installing fasteners in the third connecting hole 330 and the fourth connecting hole 424 .

[0079] The fourth connecting hole 424 may be a threaded hole for easy installation.

[0080] In some embodiments of the support assembly of the present invention, Figure 6-9As shown, the column 310 includes a second front side plate 312 and two side folding plates 313 formed by bending backward from the left and right edges of the second front side plate 312. The lower edges of the two side folding plates 313 are bent outward to form two second lower folding plates 370, and the two second lower folding plates 370 are both horizontally arranged.

[0081] The second connection structure 420 further includes two second supporting surfaces 422 corresponding to and affixed to the bottom surfaces of the two second lower folding plates 370 .

[0082] In this embodiment, by providing two second lower folding plates 370 and two second supporting surfaces 422, the contact area between the support column 300 and the base 400 can be further expanded, that is, the force-bearing area is increased, and the extrusion pressure generated by the support column 300 on the base 400 is reduced to prevent damage to the base 400.

[0083] On the other hand, the second lower folding plate 370 can also share the pressure of the first lower folding plate 360 ​​and transfer it to the column 310, or transfer it to the beam 200 through the upper edge of the side folding plate 313, so as to prevent the first lower folding plate 360, the second front side plate 312 and the first upper folding plate 350 from being deformed due to excessive force.

[0084] In some embodiments of the support assembly of the present invention, Fig. 9 As shown, the second connection structure 420 also includes a limiting rib 425, which protrudes upward from the edges of the first support surface 421 and the second support surface 422, and the limiting rib 425 is in contact with or has a clearance fit with the peripheral edges of the first lower folding plate 360 ​​and the second lower folding plate 370.

[0085] In this embodiment, the limiting rib 425 can limit the lower end of the support column 300. During installation, when the first lower folding plate 360 ​​and the second lower folding plate 370 are placed on the inner side of the limiting rib 425, the third connecting hole 330 can be automatically aligned with the fourth connecting hole 424, which can further improve the installation efficiency.

[0086] In some embodiments of the support assembly of the present invention, Figure 1-2 As shown, there are three support columns 300 , and three first connection structures 210 and second connection structures 420 are arranged at intervals along the length direction of the beam 200 .

[0087] In this embodiment, by arranging three support columns 300 at intervals, the connection strength between the crossbeam 200 and the base 400 can be further improved, and the rear panel 500 can be well supported in the front-to-back direction to prevent it from shaking. At the same time, since the three support columns 300 are spaced in the left-right direction, the support assembly 100 as a whole has a good structural strength in the left-to-right direction, thereby providing good support for the rear panel 500 in the left-to-right direction to prevent it from shaking.

[0088] On the other hand, when the support column 300 is only provided in the middle of the beam 200 in the left-right direction, the middle of the beam 200 is easily bent and deformed under the support force or tension of the support column 300. When three support columns 300 are provided at intervals in the lateral direction, the support force or tension of the middle of the beam 200 by the support column 300 in the middle can be reduced, thereby avoiding or reducing the bending and deformation of the middle of the beam 200.

[0089] It should be noted that the three support columns 300 may have the same or different specifications and sizes to meet design requirements. Preferably, the three support columns 300 have the same specifications to reduce the number of parts and save mold costs.

[0090] In some embodiments of the support assembly of the present invention, Figure 1-2 As shown, the distance w between two adjacent support columns 300 is greater than or equal to 150 mm.

[0091] In this embodiment, the structural strength of the support assembly 100 along the left-right direction can be enhanced by lengthening the distance between two adjacent support columns 300 .

[0092] In particular, since the spacing between two adjacent support columns 300 is greater than or equal to 150 mm, the spacing between the two support columns 300 on the left and right sides is equal to or greater than 300 mm. When producing or repairing parts on the rear side of the support columns 300, after the support column 300 in the middle is disassembled, there is enough operating space between the two support columns 300 on the left and right sides, and there is no need to disassemble the two support columns 300 on the left and right sides, thereby improving production or repair efficiency.

[0093] In some embodiments of the support assembly of the present invention, Figure 1-2 As shown, the first connection structure 210 and the second connection structure 420 are evenly spaced apart along the length direction of the crossbeam 200. That is, the three support columns 300 are evenly spaced apart along the left-right direction.

[0094] Preferably, one support column 300 is located in the middle of the beam 200 in the left-right direction, and the other two support columns 300 are located at both ends of the beam 200 .

[0095] In some embodiments of the air conditioner indoor unit of the present utility model, Figure 1 As shown, the air conditioner indoor unit includes a base 400, a rear panel 500 and a support assembly 100 of any one of the above embodiments or a combination of the embodiments.

[0096] The air conditioner indoor unit further comprises a front panel, which is surrounded by a rear panel 500 to form a housing of the air conditioner indoor unit. The support assembly 100 is located between the front panel and the rear panel 500.

[0097] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the contents disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
