[0031] The principles and features of the present application are described below in conjunction with the accompanying drawings, and the examples are only used to explain the present application and not to limit the scope of the present application.

[0032] As Figures 2 to 5 shown, the present application provides a chassis 1 for a wall-mounted air conditioner indoor unit. The chassis 1 is provided with a limiting buckle 121 and a reinforcing structure, the limiting buckle 121 is arranged to be clamped with the limiting clamping hole 211 of the wall-hanging plate 2 to limit the cooperation of the chassis 1 and the wall-hanging plate 2, as Figure 7 and Figure 9 shown. The reinforcing structure is arranged to reinforce the structure of the limiting buckle 121. The reinforcing structure can be arranged to be directly or indirectly connected with the limiting buckle 121.

[0033] The chassis 1 provided by the present application can improve the structural strength of the limiting buckle 121 by adding a reinforcing structure to the chassis 1 to reinforce the structure of the limiting buckle 121, thereby facilitating the improvement of the shear resistance of the limiting buckle 121, and further facilitating the prevention of the limiting buckle 121 from cracking or breaking during the drop test to cause assembly failure.

[0034] In some exemplary embodiments, as Figure 1 and Figure 2As shown, the number of limiting buckles 121 can be multiple, the number of limiting buckle holes 211 is equal to the number of limiting buckles 121 and one-to-one correspondence, through the cooperation of multiple limiting buckles 121 and multiple limiting buckle holes 211, to improve the limiting reliability of the chassis 1 and the wall hanging plate 2. The number of reinforcing structures is multiple, and the multiple reinforcing structures correspond one-to-one to the multiple limiting buckles 121, so as to ensure that each limiting buckle 121 has good structural strength to prevent it from cracking or breaking in the drop test.

[0035] In some exemplary embodiments, one end of the limiting buckle 121 is provided with an abutting portion 1213, which is arranged to abut the hole wall of the limiting buckle hole 211, as shown in Figure 10 The reinforcing structure includes a first reinforcing portion provided on the abutting portion 1213.

[0036] In some exemplary embodiments, when installed, the wall hanging plate 2 is fixed on the wall and located at the rear side of the wall-mounted air conditioner indoor unit, so the chassis 1 is located at the front side of the wall hanging plate 2, as shown in Figure 9 As shown, one end (front end) of the limiting buckle 121 is provided with an abutting portion 1213, as shown in Figure 10 The abutting portion 1213 is arranged to abut the hole wall of the limiting buckle hole 211, as shown in Figure 10 The reinforcing structure includes a first reinforcing portion provided on the abutting portion 1213.

[0037] Since the abutting portion 1213 abuts the hole wall of the limiting buckle hole 211, in the drop test, the abutting portion 1213 is the main force receiving portion of the shearing force applied by the wall hanging plate 2 to the limiting buckle 121, so the first reinforcing portion is arranged on the abutting portion 1213, which can effectively strengthen the abutting portion 1213, and is conducive to improving the shearing resistance of the abutting portion 1213, thereby reducing the risk of cracking or breaking of the limiting buckle 121.

[0038] In some embodiments, the limiting buckle 121 is arranged as a hollow convex as shown in Figure 3 and Figure 10 The abutting portion 1213 is provided with a first opening 1211 in communication with the internal space of the convex, and the first reinforcing portion includes a reinforcing flange 122 arranged along the circumference of the first opening 1211, as shown in Figure 5 The structure is simple, easy to process and form, and has good reinforcing effect.

[0039] The limiting buckle 121 is provided as a convex structure with an inner hollow, facilitating molding and being easy to deform elastically to reduce the difficulty of the limiting buckle 121 being clamped into the limiting buckle hole 211, but also resulting in a relatively low structural strength. Therefore, the reinforcing flange 122 is provided at the first opening 1211 of the convex structure in a circumferential direction, which can effectively weaken the shear force received by the limiting buckle 121 and effectively improve the strength of the limiting buckle 121, thereby preventing the limiting buckle 121 from cracking or breaking in a drop test.

[0040] Of course, the first reinforcing portion is not limited to the structure of the reinforcing flange 122, and can also be a reinforcing rib 123, a reinforcing column, or other shaped reinforcing structures.

[0041] In some embodiments, as shown in Figure 5 , the reinforcing flange 122 is provided at the inner edge of the first opening 1211 and protrudes inwardly of the first opening 1211. Since the inner side of the first opening 1211 is a hollow space, it is easier to deform, and the outer side of the first opening 1211 is connected to other structures of the chassis 1. Therefore, the reinforcing flange 122 is provided at the inner edge of the first opening 1211, which is beneficial to better improve the structural strength of the limiting buckle 121 and also has more appropriate space to set the reinforcing flange 122.

[0042] Of course, the position of the reinforcing flange 122 is not limited thereto, and can also be provided at the outer edge of the first opening 1211 or both the inner and outer edges.

[0043] In some embodiments, as shown in Figure 5 , the first opening 1211 is U-shaped, and the reinforcing flange 122 is a U-shaped flange. Of course, the shape of the first opening 1211 is not limited to U-shaped, and the shape of the reinforcing flange 122 is also not limited to a U-shaped flange.

[0044] In some exemplary embodiments, as shown in Figure 1 and Figure 2 , the chassis 1 comprises a chassis body 11 and a limiting plate 12 connected to the chassis body 11. The chassis body 11 can be provided with a mounting structure for mounting an indoor heat exchanger, a fan wheel, a motor, etc. The limiting plate 12 can be provided at the lower end of the chassis body 11 and protrude rearward.

[0045] As shown in Figure 1 and Figure 2 , the limiting buckle 121 is provided on the limiting plate 12 and protrudes to one side of the thickness direction of the limiting plate 12, and at least a part of the reinforcing structure is provided on the limiting plate 12, facilitating molding.

[0046] The upper part of the chassis body 11 can be provided with a slot 111 with an opening downward (as shown in Figure 1 and Figure 9 ), and the upper part of the wall-hanging plate 2 can be provided with a plug 22, such asFigure 1 and Figure 9 As shown. During installation, the tongue 22 can be inserted into the slot 111 first, and then the limiting buckle 121 can be snapped into the limiting hole 211 to achieve relative fixation between the chassis 1 and the wall-mounted panel 2. Furthermore, the cooperation between the tongue 22 and the slot 111 can achieve effective support of the wall-mounted panel 2 for the chassis 1 in user-side installation scenarios.

[0047] In some embodiments, the limiting plate 12 is provided with a second opening 124, such as Figure 5 As shown. The limiting buckle 121 is provided at the second opening 124 and is connected to the wall of the second opening 124. The reinforcing structure includes a second reinforcing part provided at the second opening 124.

[0048] The second reinforcing part helps to improve the connection strength between the limit buckle 121 and the limit plate 12, and helps to reduce the shear force on the limit buckle 121, thereby helping to prevent the limit buckle 121 from cracking or breaking during the drop test.

[0049] In some embodiments, the second reinforcing portion includes a reinforcing rib 123, such as Figure 4 As shown, the structure is simple, easy to process and form, and has a good reinforcing effect. Of course, the second reinforcing part is not limited to the structural form of the reinforcing rib 123, but can also adopt the reinforcing flange 122, the reinforcing column or other types of reinforcing structures.

[0050] In some embodiments, such as Figure 5 As shown, the reinforcing rib 123 includes a first sub-rib 1231 and a second sub-rib 1232. The first sub-rib 1231 is parallel to the wall of the second opening 124, and the second sub-rib 1232 is perpendicular to the wall of the second opening 124.

[0051] The first sub-rib 1231 and the second sub-rib 1232 are arranged horizontally and vertically, which can effectively reduce the shear force on the limiting buckle 121 and effectively improve the structural strength of the limiting buckle 121, thereby helping to prevent the limiting buckle 121 from cracking or breaking during drop tests.

[0052] In some embodiments, such as Figure 5 As shown, the first sub-reinforcement 1231 is arranged circumferentially along the second opening 124, the second sub-reinforcement 1232 is perpendicularly connected to the first sub-reinforcement 1231, and one first sub-reinforcement 1231 connects to multiple parallel and spaced second sub-reinforcements 1232.

[0053] In this way, the first sub-rib 1231 and multiple second sub-ribs 1232 work together to enhance the reinforcing effect, which is conducive to further improving the structural strength of the limit buckle 121, thereby helping to prevent the limit buckle 121 from cracking or breaking during drop tests.

[0054] In some embodiments, such asFigure 5 As shown, two ends of each second reinforcing rib 1232 are connected with the first reinforcing rib 1231, which can improve the reinforcing effect and further improve the structural strength of the limiting buckle 121, thereby preventing the limiting buckle 121 from being cracked or broken in the drop test.

[0055] The specific number and position of the first reinforcing rib 1231 and the second reinforcing rib 1232 can be reasonably set according to the needs, and the length of different first reinforcing ribs 1231 can also be reasonably set according to the specific position, and the length of different second reinforcing ribs 1232 can also be reasonably set according to the specific position.

[0056] In some embodiments, as shown in Figure 5 As shown, the second reinforcing part is arranged on the side of the limiting plate 12 in the thickness direction away from the limiting buckle 121, which is convenient for processing and molding, and does not interfere with the cooperation of the limiting buckle 121 and the limiting buckle hole 211.

[0057] In some exemplary embodiments, the bottom plate 1 is an injection molding part, which is convenient for designing into the required shape according to the needs. The limiting buckle 121 of the bottom plate 1 adopts a small inclined structure on the mold.

[0058] In some exemplary embodiments, the wall-hanging plate 2 is a sheet metal part, which has high structural strength, but is also easy to cut the limiting buckle 121 in the drop test, causing the limiting buckle 121 to be cracked or broken. Therefore, the embodiment of the present application adds a reinforcing structure to the bottom plate 1 to reinforce the structure of the limiting buckle 121 to prevent it from being cracked or broken in the drop test and causing assembly failure.

[0059] As shown in Figure 1 , Figure 6 , Figure 8 and Figure 9 The embodiment of the present application also provides a wall-mounted air conditioner indoor unit, which comprises the bottom plate 1 and the wall-hanging plate 2 of any one of the above embodiments. The wall-hanging plate 2 is provided with a limiting buckle hole 211, and the limiting buckle hole 211 is engaged with the limiting buckle 121 of the bottom plate 1.

[0060] The wall-mounted air conditioner indoor unit provided by the present application has all the beneficial effects of the bottom plate 1 of any one of the above embodiments, and thus is not repeated here.

[0061] In some exemplary embodiments, the wall-hanging plate 2 is provided with a limiting cooperation plate 21, which is arranged at the lower end of the wall-hanging plate 2 and protrudes forward. The limiting buckle hole 211 is arranged on the limiting cooperation plate 21, and the limiting cooperation plate 21 abuts against the upper side of the limiting plate 12 of the bottom plate 1, so that the limiting buckle 121 is clamped into the limiting buckle hole 211 from the lower side of the limiting buckle hole 211.

[0062] In some exemplary embodiments, the limiting buckle 121 is provided with a guide inclined surface 1212 to facilitate smooth buckling of the limiting buckle 121 into the limiting buckle hole 211.
