[0044] The trend of air-conditioning outdoor units is miniaturization and lightweight, requiring machines of the same capacity to be lighter, increase product cabinet volume, reduce product costs, and increase product competitiveness.
[0045] In the air conditioner outdoor unit, the chassis is the supporting base of the entire outdoor unit. In order to ensure the rigidity and strength of the chassis, the chassis is generally thicker, such as 8mm, which results in high cost and insufficient product competitiveness.
[0046] In view of this, the present invention provides a chassis, a chassis assembly and an air-conditioning outdoor unit, aiming to reduce costs while ensuring product reliability and manufacturability. Figures 1 to 11 An embodiment of the chassis provided by the present invention; Figures 12 to 15 An embodiment of a chassis assembly provided by the present invention.
[0047] In the embodiment of the present invention, please refer to the attached Figure 1 The chassis 100 includes a bottom plate 1 and a plurality of side plates 2 extending upward from the edge of the bottom plate 1, wherein the chassis 100 further includes a first reinforcement structure 3, one side of the bottom plate 1 is partially recessed and the other side of the bottom plate 1 is correspondingly protruded to form the first reinforcement structure 3; and / or the chassis 100 further includes a second reinforcement structure 4, at least one free end of the side plate 2 is bent to form the second reinforcement structure 4, or one side of the side plate 2 is partially recessed and the other side of the bottom plate 1 is correspondingly protruded to form the second reinforcement structure 4.
[0048] In the technical solution of the present invention, it can be understood that the formation method of the first reinforcing structure 3 can greatly increase the strength and rigidity of the chassis 100 at the position of the bottom plate 1 without increasing the thickness of the bottom plate 1, so that the strength and rigidity of the chassis 100 can be guaranteed while the thickness of the bottom plate 1 is reduced; the formation method of the second reinforcing structure 4 can greatly increase the strength and rigidity of the chassis 100 at the position of the side plate 2 without increasing the thickness of the side plate 2, so that the strength and rigidity of the chassis 100 can be guaranteed while the thickness of the side plate 2 is reduced, and the structures of the first reinforcing structure 3 and the second reinforcing structure 4 are simple, thereby reducing the difficulty of the manufacturing process of the chassis 100. With such a configuration, the chassis 100 uses less material, which can reduce the product cost while ensuring the reliability and manufacturability of the product.
[0049] In this embodiment, at least one free end of the side panel 2 is folded downward to form a first folded edge 41 (see Figure 2 , Figure 3 , Figure 4 and Figure 5 ), the second reinforcement structure 4 includes the first folded edge 41. Due to the arrangement of the first folded edge 41, the wall thickness of the chassis 100 at the position of the first folded edge 41 is twice the thickness of the side panel 2, which greatly increases the strength and rigidity of the side panel 2. More specifically, the first folded edge 41 can be stretched by a mold to stretch the free end of the side panel 2, bend the free end of the side panel 2 outward by 45°, and then bend it by 135° to fold it flat, and bend it in steps to avoid damage to the side panel 2 and ensure the reliability of the structure.
[0050] It should be noted that the "inside" or "outside" in this embodiment refers to the inside of the air-conditioning outdoor unit or the outside of the air-conditioning outdoor unit when the chassis 100 is used for the air-conditioning outdoor unit, which will not be repeated below.
[0051] In this embodiment, at least one free end of the side plate 2 is bent outward to form a first inclined folded edge 42 (see Figure 2 , Fig. 9 and Fig.11), the second reinforcement structure 4 includes the first inclined folded edge 42. Due to the setting of the first inclined folded edge 42, the strength and rigidity of the chassis 100 at the position of the side panel 2 can be greatly increased without increasing or slightly increasing the area of the side panel 2, effectively reducing the risk of product falling and deformation, thereby controlling product costs and ensuring product reliability. Specifically, the free end of the side panel 2 begins to bend from 1 / 2 to 2 / 3 of the height of the side panel 2, and the outward bending angle of the first inclined folded edge 42 is 20° to 60°, which can better ensure the overall strength and rigidity of the side panel 2. In a specific embodiment, the outward bending angle of the first inclined folded edge 42 is 45°, so that the side panel 2 obtains better strength and rigidity.
[0052] In this embodiment, the bottom plate 1 is arranged in an elongated shape so that the bottom plate 1 has a long side and a short side; at least one of the side plates 2 located on the long side is provided with the second reinforcing structure 4. It can be understood that when the bottom plate 1 is arranged in an elongated shape, the chassis 100 is subjected to greater force in the long side direction and less force in the short side direction, and the rigidity in the long side direction needs to be strengthened. By providing the second reinforcing structure 4 on one of the side plates 2 located on the long side, the rigidity of the chassis 100 on the long side can be enhanced to ensure the reliability of the product. The present invention does not specifically limit the form in which the two side plates 2 located on the long side are provided with the second reinforcing structure 4, and the two side plates 2 may be provided with the second reinforcing structure 4, and the two first reinforcing structures 3 are the first folded edge 41 and the first inclined folded edge 42, respectively. It can be understood that, in one embodiment, the first inclined folded edge 42 is arranged corresponding to the condenser of the air conditioner outdoor unit, which can increase the water receiving area of the chassis 100 corresponding to the condenser, so that the condensed water of the condenser flows into the chassis 100 and passes through the centralizing hole 7 (see Figure 3 ) drainage to avoid condensation water dripping and improve product experience.
[0053] In this embodiment, the bottom plate 1 is arranged in an elongated shape; the first reinforcing structure 3 includes a first reinforcing rib 31 (see Figure 6 , Figure 7 and Fig. 9 ), the first reinforcing rib 31 extends along the length direction of the bottom plate 1. It can be understood that the first reinforcing rib 31 extending along the length direction of the bottom plate 1 can strengthen the rigidity of the bottom plate 1 in its length direction, ensure the overall strength and rigidity of the bottom plate 1, and thus the reliability of the product. More specifically, the first reinforcing rib 31 can be provided with a plurality of first reinforcing ribs 31, and the plurality of first reinforcing ribs 31 are distributed along the width direction of the bottom plate 1, which can effectively ensure the rigidity of the chassis 100 at the position of the bottom plate 1.
[0054] In this embodiment, the first reinforcement structure 3 includes a mounting boss 34 and a second reinforcement rib 32 (see Figure 8 ), the mounting boss 34 is used to mount the compressor, the second reinforcing rib 32 extends along the circumference of the mounting boss 34 and is spaced apart from the mounting boss 34. It is understandable that the compressor is one of the most important components in the air conditioner outdoor unit. If the compressor is not fixed stably, it will cause abnormal noise or pipe breakage caused by excessive vibration of the pipeline. By setting the mounting boss 34 and the second reinforcing rib 32, the rigidity of the base plate 1 corresponding to the position where the compressor is installed can be strengthened, so that the position is not easy to deform, forming a relatively stable support for the compressor, and the compressor is stably installed to avoid pipeline vibration and noise problems, thereby ensuring the reliability of the product. Specifically, there are three mounting bosses 34, and the compressor is fixed by three bolts 8.
[0055] The present invention does not specifically limit the structure of the second reinforcing rib 32. The second reinforcing rib 32 may be an arc-shaped reinforcing rib, and a plurality of the arc-shaped reinforcing ribs are distributed along the circumference of the mounting boss 34. In the present embodiment, the second reinforcing rib 32 includes an annular reinforcing rib arranged on the periphery of the mounting boss 34. The second reinforcing rib 32 is arranged along the circumference of the mounting boss 34, which is beneficial to ensure the overall stiffness of the mounting boss 34, thereby ensuring the reliability of the product.
[0056] In this embodiment, the first reinforcement structure 3 further includes a plurality of third reinforcement ribs 33 (see Figure 8 ), one end of each of the third reinforcing ribs 33 is close to the center of the mounting boss 34 and extends to the annular reinforcing rib (second reinforcing rib 32), and the other end of each of the third reinforcing ribs 33 extends in a direction away from the center of the mounting boss 34, and a plurality of the third reinforcing ribs 33 are distributed at intervals along the circumference of the mounting boss 34. The third reinforcing ribs 33 and the annular reinforcing ribs strengthen the rigidity of the mounting boss 34 in all directions, and can better strengthen the rigidity of the base plate 1 corresponding to the compressor installation position, thereby forming a more stable support for the compressor, making the compressor installation more stable, and further ensuring the reliability of the product.
[0057] In one embodiment, the thickness of the side plate 2 is less than 8 mm; in another embodiment, the thickness of the bottom plate 1 is less than 8 mm. The above two embodiments can be selected or exist at the same time. It can be understood that by setting the first reinforcement structure 3 and / or the second reinforcement structure 4, the strength and rigidity of the chassis 100 can be guaranteed while reducing the thickness of the bottom plate 1 and / or the side plate 2, thereby reducing the product cost while ensuring the reliability and manufacturability of the product.
[0058] In one embodiment, the thickness of the side plate 2 is 6 mm, and in another embodiment, the thickness of the bottom plate 1 is 6 mm. The above two embodiments can be selected or exist at the same time. It can be understood that the 6 mm raw material thickness, compared with the raw material thickness of 8 mm or even greater in the related art, can still reduce the overall material usage of the chassis 100 and reduce product costs even if the first reinforcement structure 3 and / or the second reinforcement structure 4 cause the area of the raw material to increase slightly.
[0059] In this embodiment, the bottom plate 1 is provided with a through hole 11 (see Figure 3 ), the edge of the through hole 11 is folded toward one side of the bottom plate 1 to form a second folded edge stacked with the bottom plate 1 (in the figure, the edge of the through hole 11 is folded toward the outside of the bottom plate 1 to form the second folded edge, so the second folded edge cannot be seen from the inside of the bottom plate 1, and the second folded edge is understood with reference to the position of the mounting hole 5), and the chassis 100 is also provided with a mounting hole 5, and the mounting hole 5 is arranged at a relative position between the second folded edge and the bottom plate 1. It can be understood that the setting of the mounting hole 5 can be used to penetrate fasteners (such as screws) to install other components of the air-conditioning outdoor unit on the chassis 100. Through the setting of the second folded edge, the wall thickness of the chassis 100 at the second folded edge position can be twice the thickness of the bottom plate 1, which can avoid structural loosening or damage at the mounting hole 5 (such as the risk of screw slippage), thereby ensuring the reliability of the product. Similarly, please refer to Figure 5 The mounting hole 5 can also be set through the first folded edge 41 and the side panel 2 to facilitate the connection between the side panel 2 and other components of the air conditioner outdoor unit, and to avoid loosening and damage of the structure at the mounting hole 5, thereby ensuring the reliability of the product.
[0060] The present invention also provides a chassis assembly 1000 (see Fig.12 and Fig.14 ), used for an air conditioner outdoor unit, the chassis assembly 1000 comprises a motor bracket 300, a valve plate 200, and the chassis 100 as described above; the lower end of the motor bracket 300 is supported on the bottom plate 1; the lower end of the valve plate 200 is supported on the bottom plate 1. The chassis 100 refers to all the above embodiments, and since the chassis assembly 1000 has all the above technical solutions, it has at least the technical effects of all the above embodiments, which will not be repeated here.
[0061] In this embodiment, the side plate 2 includes a side plate section corresponding to the valve plate 200, the side plate section is located outside the valve plate 200, and the side plate section extends upward from the periphery of the bottom plate 1, and the free end of the side plate section is bent outward to form a second inclined fold 6 (see Figure 8, Fig.10 and Fig.13 ), the second inclined folded edge 6 can increase the water receiving area of the chassis 100 corresponding to the valve plate 200, can prevent the condensed water of the valve plate 200 from overflowing and dripping, and improve the user experience of the product.
[0062] In this embodiment, the outer side of the valve plate 200 is provided with a first buckle 210 (see Fig.13 ), the first clip 210 is clamped on the upper edge of the side panel 2. In this way, the first clip 210 can fix the valve plate 200. Specifically, the valve plate 200 and the side panel 2 can also have corresponding fastening holes for inserting fasteners to further fix the valve plate 200. In the related art, the valve plate 200 includes legs extending in the horizontal direction, and the legs and the bottom plate 1 have corresponding fastening holes for inserting fasteners for fastening, which has the risk of condensed water flowing out of the air conditioner outdoor unit 1000 from the gap between the fastening holes of the bottom plate 1 and the fasteners. In this embodiment, the valve plate 200 is fixed by arranging the first clip 210 on the outer side of the valve plate 200, which can avoid this risk and improve the user experience.
[0063] In this embodiment, the bottom plate 1 is provided with a second buckle 9 (see Figure 2 , Fig.14 and Fig.15 ), the motor bracket 300 includes a support portion 310 extending in the horizontal direction, and the second clip 9 is clamped on the edge of the support portion 310. In the related art, the installation process of the motor bracket 300 includes positioning the motor bracket 300 with the motor already installed on the chassis 100, and subsequently fastening the motor bracket 300 with fasteners. Before fastening with fasteners, since the motor has been installed on the motor bracket 300, the motor bracket 300 is easy to fall due to the influence of gravity. By setting the second clip 9, the second clip 9 can be connected to the edge of the support portion 310 to form a rotating shaft. By using the principle of leverage, the motor bracket 300 is locked to prevent the motor bracket 300 from falling, thereby improving the manufacturing efficiency of the product.
[0064] The present invention also provides an air-conditioning outdoor unit, which includes a chassis assembly 1000 as described above. The chassis assembly 1000 refers to all the above-mentioned embodiments. Since the chassis assembly 1000 has all the above-mentioned technical solutions, it at least has the technical effects of all the above-mentioned embodiments, which will not be repeated here.
[0065] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
