[0036] Figure 1is a schematic structural diagram of a packaging structure of an air conditioner indoor unit according to an embodiment of the utility model, such as Figure 1 As shown, and refer to Figures 2 to 4 The embodiment of the utility model provides a packaging structure of an air conditioner indoor unit, and the packaging structure of the air conditioner indoor unit includes two end pads 200 and a middle pad 100. The two end pads 200 are respectively mounted on both ends of the length direction of the air conditioner indoor unit. The middle pad 100 is mounted on the outer periphery of the air conditioner indoor unit and is located between the two end pads 200 in the length direction of the air conditioner indoor unit. The lower surface of the middle pad 100 is not higher than the lower surfaces of the two end pads 200.

[0037] Take the two end spacers 200 as an example, which are arranged at a left-right interval.

[0038] In this embodiment, the end pads 200 are used to support the air-conditioning indoor unit and protect the two ends of the air-conditioning indoor unit in the length direction to prevent the air-conditioning indoor unit from being damaged by collisions during transportation. The middle pad 100 supports and protects the middle section of the air-conditioning indoor unit in the length direction to further prevent the air-conditioning indoor unit from being damaged by collisions during transportation. The lower surface of the middle pad 100 is not higher than the lower surfaces of the two end pads 200. During handling or transportation, the bottom of the middle pad 100 will be squeezed by the outer packaging, such as the outer packaging box, so that the middle pad 100 generates friction with the outer packaging box and the air-conditioning indoor unit housing, preventing the middle pad 100 from moving relative to the air-conditioning indoor unit. The protection of the air-conditioning indoor unit during handling and transportation is strengthened, the quality of the air-conditioning indoor unit after transportation is guaranteed, and the user experience is improved.

[0039] Preferably, in some embodiments of the packaging structure of the present invention, Figure 1 As shown, the lower surface of the middle block 100 is lower than the lower surfaces of the two end blocks 200 .

[0040] In this embodiment, the lower surface of the middle pad 100 is lower. Compared with the case where the lower surface of the middle pad 100 is flush with the lower surfaces of the two end pads 200, the bottom end of the middle pad 100 can be subjected to greater pressure, thereby making the middle pad 100 subjected to greater static friction, more effectively preventing the movement of the middle pad 100, and improving the protection ability of the middle pad 100 to the air-conditioning indoor unit during handling and transportation.

[0041] In some other embodiments of the packaging structure of the present invention, the lower surface of the middle cushion block 100 may also be flush with the lower surfaces of the two end cushion blocks 200 .

[0042] In some embodiments of the packaging structure of the present invention, Figure 3As shown, the middle pad 100 includes a first portion 110 and a second portion 120 disposed up and down. A mounting groove 130 is defined between the first portion 110 and the second portion 120 to surround the air conditioner indoor unit from the upper and lower sides respectively. The lower surface of the second portion 120 is the lower surface of the middle pad 100.

[0043] In this embodiment, the first part 110 and the second part 120 surround the air conditioner indoor unit from the upper and lower sides respectively. When removing the packaging structure, the first part 110 can be taken out first, and then the air conditioner indoor unit can be taken out. When putting the packaging structure, the second part 120 can be placed first, and then the air conditioner indoor unit can be placed, and the air conditioner indoor unit can be placed in the installation groove 130. There is no need to move the middle pad 100 to both ends of the air conditioner indoor unit for installation or removal, which simplifies the removal and installation steps of the packaging structure and makes the operation of workers easier.

[0044] Furthermore, in some embodiments of the packaging structure of the present invention, the first part 110 and the second part 120 can be fixedly connected by gluing or snapping to prevent the first part 110 or the second part 120 from shifting during transportation and causing damage to the air conditioner indoor unit.

[0045] In some embodiments of the packaging structure of the present invention, Figure 4 As shown, at least one trapezoidal rib 111 protruding downward is provided on the first portion 110. At least one trapezoidal groove 121 opening upward is provided on the second portion 120. At least one trapezoidal rib 111 is inserted into one trapezoidal groove 121.

[0046] In this embodiment, the number of the trapezoidal ribs 111 is consistent with the number of the trapezoidal grooves 121. The size of the opening at the upper end of the trapezoidal groove 121 is larger than the size of the lower end of the trapezoidal rib 111. During the process of installing the first part 110 on the second part 120, the position of the first part 110 may be deviated. When moving downward, the left and right side walls of the trapezoidal groove 121 guide the trapezoidal rib 111 so that the first part 110 is in the correct installation position after installation, that is, the first part 110 and the second part 120 are matched in profile. This packaging structure does not require the first part 110 to be fully aligned before being installed on the second part 120, which simplifies the installation method, improves the installation speed, and thus improves the packaging speed of the air conditioner indoor unit.

[0047] Preferably, in some embodiments of the packaging structure of the present invention, Figure 4 As shown, a downwardly protruding trapezoidal rib 111 is provided on the first portion 110. A trapezoidal groove 121 with an upward opening is provided on the second portion 120.

[0048] In this embodiment, only one set of mutually matching trapezoidal ribs 111 and trapezoidal grooves 121 is provided, which simplifies the production and manufacturing of the mold, makes it easier to form the middle pad 100, and reduces the production cost of the middle pad 100.

[0049] In other embodiments of the packaging structure of the present invention, the first part 110 is provided with two or more downwardly protruding trapezoidal ribs 111. The second part 120 is provided with the same number of trapezoidal grooves 121 with upward openings as the number of trapezoidal ribs 111 to improve the stability of the clamping between the first part 110 and the second part 120.

[0050] In some other embodiments of the packaging structure of the present invention, at least one trapezoidal groove 121 with an opening facing downward may be provided on the first portion 110. At least one trapezoidal rib 111 protruding upward may be provided on the second portion 120.

[0051] In some embodiments of the packaging structure of the present invention, Figure 4 As shown, the trapezoidal ribs 111 and the trapezoidal grooves 121 both extend frontward and rearward.

[0052] In this embodiment, the trapezoidal groove 121 passes through the inner and outer surfaces of the second part 120 in the front-to-back direction, and the trapezoidal rib 111 is snapped into the trapezoidal groove 121 to limit the relative movement of the first part 110 and the second part 120 in the left-right direction to prevent the first part 110 or the second part 120 from sliding during transportation.

[0053] In some other embodiments of the packaging structure of the present invention, the trapezoidal groove is in the shape of a blind hole, so that the relative movement of the first part 110 and the second part 120 in the horizontal direction is limited by the cooperation between the trapezoidal groove and the trapezoidal rib.

[0054] In some embodiments of the packaging structure of the present invention, the inner surface of the installation groove 130 matches the outer peripheral surface of the air conditioner indoor unit.

[0055] In this embodiment, the inner surface of the mounting groove 130 fits the outer periphery of the air conditioner indoor unit, reducing the pressure of the inner surface of the mounting groove 130 on the outer periphery of the air conditioner indoor unit, so as to reduce the situation that the air conditioner indoor unit is squeezed and damaged by the mounting groove 130 during handling and transportation. In addition, the inner surface of the mounting groove 130 fits the outer periphery of the air conditioner indoor unit to prevent the middle pad 100 from moving in the front-to-back direction relative to the air conditioner indoor unit, thereby improving the protection performance of the middle pad 100.

[0056] In some embodiments of the packaging structure of the present invention, Figure 1 As shown, the second portion 120 is located at the lower side of the air outlet of the indoor unit of the air conditioner.

[0057] In this embodiment, an air guide plate or a swing blade is provided at the air outlet of the air conditioner indoor unit. After the air conditioner indoor unit is placed in the second part 120, the highest point of the second part 120 is lower than the air outlet. The second part 120 will not generate pressure on the air guide plate or the swing blade at the air outlet, thereby preventing the air guide plate or the swing blade from being damaged by pressure.

[0058] Further, in some embodiments of the packaging structure of the present invention, such as Figure 1 and Figure 3 As shown, the lowest point of the first part 110 is located at the lower end of the air outlet of the air conditioner, and the first part 110 located at the outer periphery of the air outlet of the air conditioner indoor unit is spaced apart from the air outlet of the air conditioner to prevent squeezing of the air guide plate or the swing blade.

[0059] In some embodiments of the packaging structure of the present invention, the upper surface of the middle cushion block 100 is flush with the upper surfaces of the two end cushion blocks 200 .

[0060] In this embodiment, the upper surfaces of the middle pad 100 and the two end pads 200 are flush, so that the middle pad 100 and the two end pads 200 share the pressure on the upper ends, reducing the local force on the air conditioner indoor unit, and the upper surface of the middle pad 100 is subjected to friction to prevent the movement of the middle pad 100. The protection of the air conditioner indoor unit during handling and transportation is strengthened, the quality of the air conditioner indoor unit after transportation is guaranteed, and the user experience is improved.

[0061] In some embodiments of the packaging structure of the present invention, the upper surface of the middle cushion block 100 is higher than the upper surfaces of the two end cushion blocks 200 .

[0062] In this embodiment, the upper surface of the middle pad 100 is higher. Compared with the case where the upper surface of the middle pad 100 is flush with the upper surfaces of the two end pads 200, the bottom end of the middle pad 100 can be subjected to greater pressure, thereby making the middle pad 100 subjected to greater friction, more effectively preventing the movement of the middle pad 100, and improving the protection of the middle pad 100 to the air conditioner indoor unit during handling and transportation.

[0063] In some embodiments of the packaging structure of the present invention, the front surface of the middle cushion block 100 is flush with the front surfaces of the two end cushion blocks 200 .

[0064] Alternatively, the front surface of the middle block 100 is located at the front side of the front surfaces of the two end blocks 200 .

[0065] In some embodiments of the packaging structure of the present invention, the rear surface of the middle cushion block 100 is flush with the rear surfaces of the two end cushion blocks 200 .

[0066] Alternatively, the rear surface of the middle block 100 is located at the rear side of the rear surfaces of the two end blocks 200 , and the lower surface of the middle block 100 is lower than the lower surfaces of the end blocks 200 .

[0067] In some embodiments of the packaging structure of the present invention, the front surface, rear surface, upper surface and lower surface of the middle pad 100 are all flat, so as to reduce the difficulty of mold production, make the demolding of the middle pad 100 simpler, and reduce production costs.

[0068] In some embodiments of the packaging structure of the present invention, Figure 1 or Figure 2 As shown, each end pad 200 is away from the outer surface of the air conditioner indoor unit to form a material-saving groove opening outward, so as to reduce the use of materials and reduce the production cost of the packaging structure.

[0069] In some embodiments of the packaging structure of the present invention, Figure 1 or Figure 2 As shown, the width of the middle pad 100 in the length direction of the air conditioner indoor unit is smaller than the width of the end pad 200 in the length direction of the air conditioner indoor unit.

[0070] In this embodiment, the two end pads 200 play a major role in preventing shock and collision in the packaging structure, and the middle pad mainly supports and protects the middle section of the air conditioner indoor unit in the length direction, and does not need to generate a large supporting force. The width of the middle pad 100 in the length direction of the air conditioner indoor unit is reduced, and the size of the middle pad 100 is reduced to reduce materials and reduce production costs.

[0071] In some embodiments of the packaging structure of the present invention, Figure 1 As shown, the end pad 200 near the fan of the air conditioner indoor unit includes a pad body 210 and a reinforcing support plate 220 extending from the bottom plate of the pad body 210 to the middle pad 100. A receiving groove opening toward the middle pad 100 is formed in the pad body 210.

[0072] In this embodiment, the pad body 210 wraps the end of the air conditioner indoor unit to protect it. The end of the fan close to the air conditioner indoor unit is heavier and requires a higher support force. The reinforcing support plate 220 supports the bottom of the air conditioner indoor unit to prevent the air conditioner indoor unit from being squeezed or even damaged after the end pad 200 is damaged.

[0073] In some embodiments of the packaging structure of the present invention, Figure 1 As shown, the upper end of the reinforcing support plate 220 is fixedly connected to the side surface of the cushion block body 210 facing the middle cushion block 100 through a chamfered structure 221 .

[0074] In this embodiment, the reinforcing support plate 220 is fixedly connected to the cushion block body 210 via the chamfered structure 221 , thereby improving the stability of the reinforcing support plate 220 and reducing the occurrence of damage or deformation of the end cushion block 200 .

[0075] In some embodiments of the packaging structure of the present invention, the two end pads 200 may also include a pad body 210 and a reinforcing support plate 220 extending from the bottom plate of the pad body 210 to the middle pad 100.
