[0028] The principles and features of the present application will be described below with reference to the accompanying drawings. The examples given are only used to explain the present application and are not intended to limit the scope of the present application.

[0029] As Figure 1 、 Figure 2 and Figure 7 shown, some embodiments of the present application provide a box body strengthening structure for an air conditioner. The air conditioner can be, but is not limited to, a floor-standing air conditioner, a vertical wall-mounted air conditioner, etc.

[0030] The box body strengthening structure includes: a rear box 1 and a volute 2.

[0031] Among them, as Figure 4 shown, the rear box 1 is provided with a concave cavity 11 with an opening facing forward. At least part of the volute 2 is arranged in the concave cavity 11. A strengthening part 21 is convexly provided on the outer side wall of the volute 2, as Figure 1As shown, the reinforcing part 21 is located inside the front opening of the rear box body 1 and is fixedly connected to the rear box body 1 to reinforce the rear box body 1.

[0032] One reinforcing part 21 can be provided. For example, one reinforcing part 21 is provided on the right side of the volute, and is fixedly connected to the right end of the rear box body 1, then one sheet metal part for reinforcing the rear box body 1 can be cancelled. Or, two reinforcing parts 21 can also be provided. For example, one reinforcing part 21 is provided on each of the left and right sides of the volute, and is fixedly connected to the left and right ends of the rear box body 1, then two sheet metal parts for reinforcing the rear box body 1 can be cancelled.

[0033] Therefore, for the box body reinforcing structure provided by the embodiment of the present application, the rear box body 1 is reinforced through the reinforcing part 21 on the volute 2, and at least one sheet metal part for reinforcing the rear box body 1 can be cancelled, reducing the number of parts and simplifying the assembly process, thereby being beneficial to reducing the production cost and improving the manufacturing efficiency.

[0034] Among them, the volute 2 can be completely located inside the rear box body 1, or partially located inside the rear box body 1, and there is also a part located inside the front box body.

[0035] In some exemplary embodiments, the reinforcing part 21 and the volute 2 are of an integral structure, as Figure 6 shown.

[0036] In some exemplary embodiments, the reinforcing part 21 includes a reinforcing plate 211 extending along the height direction (i.e., the up and down direction) of the rear box body 1, as Figure 7 and Figure 8 shown. The reinforcing plate 211 is provided with a fixing part, and the inner side wall of the rear box body 1 is provided with a fixing cooperation part, and the fixing part is fixedly connected to the fixing cooperation part.

[0037] The reinforcing plate 211 can extend from the top of the volute 2 to the bottom of the volute 2, providing reliable support and reinforcement for the rear box body 1.

[0038] In some embodiments, one of the fixing part and the fixing cooperation part includes a fixing hole 213 (as Figure 3 and Figure 6 shown), and the other includes a fixing post 14 (as Figure 3 , Figure 4 , Figure 5 and Figure 8 shown), and the fixing post 14 and the fixing hole 213 are fixedly connected through a fastener.

[0039] The fastener has high connection strength and is relatively firmly fixed. The fastener can be, but is not limited to, a screw. The fixing post 14 can be provided with a threaded hole, and the fixing hole 213 can be a smooth hole, and the screw passes through the smooth hole and is threadedly connected to the fixing post 14 to realize the fixed connection between the reinforcing plate 211 and the rear box body 1.

[0040] The number of the fixing posts 14 and the fixing holes 213 is not limited. In some embodiments, the number of the fixing posts 14 is multiple, such as Figure 4 and Figure 8 shown. The multiple fixing posts 14 are arranged at intervals in the up-and-down direction. The number of the fixing holes 213 is multiple, such as Figure 6 shown. The multiple fixing holes 213 are arranged at intervals in the up-and-down direction. In this way, the reinforcing plate 211 and the rear box body 1 can be fixedly connected through multiple fasteners, which is beneficial to the uniform force of the volute 2 and the rear box body 1 and is beneficial to improving the connection reliability.

[0041] In one example, the fixing part includes the fixing hole 213, and the fixing and mating part includes the fixing post 14, which is convenient for hiding the screw inside the rear box body 1 and is beneficial to improving the aesthetics of the air conditioner.

[0042] The inner side wall of the rear box body 1 is convexly provided with a supporting part 15, such as Figure 5 shown. The fixing post 14 is arranged on the supporting part 15. In this way, it is convenient to reasonably set the position of the fixing hole 213 as required, which is beneficial to avoiding the position of the fixing hole 213 being too close to the edge of the reinforcing plate 211.

[0043] The supporting part 15 includes a supporting rib 151 connected to the outer side wall of the fixing post 14, such as Figure 5 shown. The supporting rib 151 can play a strengthening role, which is beneficial to improving the strength of the fixing post 14, and further beneficial to improving the connection strength between the reinforcing plate 211 and the rear box body 1.

[0044] In other examples, the fixing part includes the fixing post 14, and the fixing and mating part includes the fixing hole 213.

[0045] Of course, the structural forms of the fixing part and the fixing and mating part are not limited to the above ways. For example, the fixed connection can also be realized through a clamping structure, a welding structure and other ways.

[0046] In some embodiments, such as Figure 2 and Figure 3 shown, the fixing post 14 and the fixing hole 213 are arranged opposite to each other in the front-back direction, so that the fastener is inserted through the fixing post 14 and the fixing hole 213 in the front-back direction. This is beneficial to reducing the installation difficulty of the fastener and is beneficial to improving the assembly efficiency.

[0047] Of course, the installation direction of the fastener is not limited to the front-back direction, and can also be adjusted to other directions as required.

[0048] In some exemplary embodiments, the reinforcing plate 211 is provided with a positioning part, and the inner side wall of the rear box body 1 is provided with a positioning and mating part. The positioning part and the positioning and mating part cooperate to position the relative position of the volute 2 and the rear box body 1 and limit the bending deformation of the rear box body 1 in the left-right direction.

[0049] This facilitates the pre-positioning between the volute 2 and the rear box body 1 through the positioning part and the positioning and mating part first, and then the fixed connection through the fasteners, which is beneficial to reducing the assembly difficulty between the volute 2 and the rear box body 1 and improving the assembly efficiency.

[0050] Moreover, since the size of the rear box body 1 in the up and down direction is usually relatively large, it is prone to bending deformation in the left and right directions due to force. Through the cooperation of the positioning part and the positioning and mating part, it is beneficial to prevent the side walls of the rear box body 1 from moving sideways and causing the rear box body 1 to bend, that is, it can limit the bending deformation of the rear box body 1 in the left and right directions, thereby improving the strength of the rear box body 1.

[0051] In some embodiments, one of the positioning part and the positioning and mating part includes a first card slot 214 (as shown in Figure 3 、 Figure 6 ), and the other includes a first snap 12 (as shown in Figure 3 、 Figure 4 、 Figure 7 and Figure 8 ). The first snap 12 includes a first connecting part 121 and a first clamping part 122 connected to the first connecting part 121, as shown in Figure 5 . The first clamping part 122 is arranged to be inserted into the first card slot 214 in the front and rear direction to limit the bending deformation of the rear box body 1 in the left and right directions.

[0052] The first connecting part 121 is mainly used to realize the connection between the first snap 12 and the rear box body 1 (when the first snap 12 is arranged on the rear box body 1) or the reinforcing plate 211 (when the first snap 12 is arranged on the reinforcing plate 211). The shape of the first connecting part 121 is not limited and can be, but is not limited to, shapes such as plate-shaped and block-shaped. The first clamping part 122 is mainly used to realize the positioning function and the limiting function. The shape of the first clamping part 122 is not limited and can be, but is not limited to, shapes such as block-shaped and plate-shaped.

[0053] The number of the first snaps 12 and the first card slots 214 is not limited. In some embodiments, the number of the first snaps 12 is multiple, as shown in Figure 4 , and the multiple first snaps 12 are arranged at intervals in the up and down direction. The number of the first card slots 214 is multiple, as shown in Figure 6 , and the multiple first card slots 214 are arranged at intervals in the up and down direction. In this way, the reinforcing plate 211 and the rear box body 1 can be clamped by the multiple first snaps 12 and the multiple first card slots 214, which is beneficial to the uniform stress between the volute 2 and the rear box body 1, beneficial to improving the connection reliability, and beneficial to improving the strength of the rear box body 1.

[0054] In an example, the positioning part includes the first card slot 214, and the positioning and mating part includes the first snap 12.

[0055] In other examples, the positioning portion includes a first buckle 12, and the positioning and mating portion includes a first slot 214.

[0056] Of course, the positioning portion and the positioning and mating portion are not limited to the structural form of the first slot 214 and the first buckle 12. For example, they can also be in the structural forms of a positioning post and a positioning hole, or a positioning protrusion and a positioning groove, etc.

[0057] In some exemplary embodiments, the reinforcing plate 211 is provided with a limiting portion, and the inner side wall of the rear box body 1 is provided with a limiting and mating portion. The limiting portion cooperates with the limiting and mating portion to limit the rear box body 1 from bending and deforming in the front-rear direction.

[0058] Since the size of the rear box body 1 in the up-down direction is usually relatively large, it is prone to bending and deforming in the front-rear direction due to force, which affects the straightness of the rear box body 1. Through the cooperation of the limiting portion and the limiting and mating portion, it is beneficial to prevent the rear box body 1 from bending and deforming in the front-rear direction, thereby being beneficial to ensuring the straightness of the rear box body 1.

[0059] In some embodiments, one of the limiting portion and the limiting and mating portion includes a second slot 215 (as Figure 3 , Figure 6 shown), and the other includes a second buckle 13 (as Figure 3 , Figure 4 , Figure 7 and Figure 8 shown). The second buckle 13 includes a second connecting portion 131 and a second clamping portion 132 connected to the second connecting portion 131 and bent relative to the second connecting portion 131, as Figure 5 shown. The second connecting portion 131 is arranged to be inserted into the second slot 215 in the front-rear direction, and the second clamping portion 132 is arranged to pass through the second slot 215 and hook the rear box body 1 or the reinforcing plate 211 in the front-rear direction to limit the rear box body 1 from bending and deforming in the front-rear direction.

[0060] The second connecting portion 131 is used to realize the connection between the second buckle 13 and the rear box body 1 (when the second buckle 13 is provided on the rear box body 1) or the reinforcing plate 211 (when the second buckle 13 is provided on the reinforcing plate 211), and passes through the second slot 215 to ensure that the second clamping portion 132 can hook the rear box body 1 (when the second buckle 13 is provided on the reinforcing plate 211) or the reinforcing plate 211 (when the second buckle 13 is provided on the rear box body 1). The shape of the second connecting portion 131 is not limited and can be, but is not limited to, shapes such as plate-shaped and block-shaped. The second clamping portion 132 is mainly used to realize the limiting function. The shape of the second clamping portion 132 is not limited and can be, but is not limited to, shapes such as block-shaped and plate-shaped.

[0061] The number of the second buckle 13 and the second slot 215 is not limited. In some embodiments, the number of the second buckle 13 is multiple, such as Figure 4As shown, a plurality of second buckles 13 are arranged at intervals in the up and down direction. The number of the second card slots 215 is plural, such as Figure 6 As shown, a plurality of second card slots 215 are arranged at intervals in the up and down direction. In this way, the reinforcing plate 211 and the rear box body 1 can be clamped through the plurality of second buckles 13 and the plurality of second card slots 215, which is beneficial to the uniform force of the volute 2 and the rear box body 1, beneficial to improving the connection reliability, and beneficial to improving the strength of the rear box body 1.

[0062] In one example, the limiting part includes the second card slot 215, and the limiting and cooperating part includes the second buckle 13.

[0063] In other examples, the limiting part includes the second buckle 13, and the limiting and cooperating part includes the second card slot 215.

[0064] Of course, the limiting part and the limiting and cooperating part are not limited to the structural forms of the second card slot 215 and the second buckle 13. For example, they can also be in the structural forms of a limiting post and a limiting hole, or a limiting protrusion and a limiting groove, etc.

[0065] Such as Figure 3 As shown, the length of the first card slot 214 in the up and down direction can be greater than the length of the first clamping part 122 in the up and down direction, so that the first clamping part 122 can move up and down along the first card slot 214. In this way, when connecting the volute 2 and the rear box body 1, the first clamping part 122 can be inserted into the first card slot 214 in the front and back direction and the second clamping part 132 can pass through the second card slot 215 first, and then the volute 2 is moved in the up and down direction to make the second clamping part 132 hook the reinforcing plate 211 or the rear box body 1. In this way, through two steps, the alignment between the volute 2 and the rear box body 1 can be realized, and then the volute 2 and the rear box body 1 can be firmly connected by screws.

[0066] In some exemplary embodiments, the reinforcing plate 211 includes a plate body 2111 and a flange 2112, such as Figure 3 As shown. The flange 2112 is connected to one end (left end or right end) of the plate body 2111 away from the volute 2 and abuts against the inner side wall of the rear box body 1, and the fixing part is arranged on the plate body 2111.

[0067] In this way, the flange 2112 can also play a role in limiting the rear box body 1, which is beneficial to preventing the rear box body 1 from being bent and deformed.

[0068] In some exemplary embodiments, the reinforcing part 21 further includes reinforcing ribs 212, such as Figure 3 As shown, the reinforcing ribs 212 are arranged on the reinforcing plate 211.

[0069] The number of the reinforcing ribs 212 is not limited. In some embodiments, the number of the reinforcing ribs 212 is plural, such as Figure 3As shown, the reinforcing ribs 212 extend along the width direction of the plate body 2111, and a plurality of reinforcing ribs 212 are arranged at intervals along the height direction of the rear box body 1.

[0070] The first buckle 12 and the second buckle 13 can also be provided with reinforcing ribs 212 for reinforcement.
