[0025] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.

[0026] Reference is made below to Figures 1 - 4 describe the packaging structure 10 according to an embodiment of the present invention. The packaging structure 10 of this embodiment is used to package the air conditioner indoor unit 20. For example, the packaging structure 10 can be used to package a wall-mounted air conditioner, and the packaging structure 10 of this embodiment can also be used to package a floor-standing air conditioner, and can also be used to package an outdoor unit of an air conditioner, an integrated air conditioner, and so on. In addition, the packaging structure 10 of this embodiment can also be used to package other electrical appliances with buffer and shock absorption requirements.

[0027] As Figure 1 shown, the packaging structure 10 according to an embodiment of the present invention includes: a foam member 11 and an EPE member 12. The foam member 11 has a cavity 111 with an opening 112 on one side in the first direction; the EPE member 12 is disposed in the cavity 111 and is in interference fit with the inner wall of the cavity 111.

[0028] Specifically, as Figure 2 shown, a cavity 111 is formed on the foam member 11. The left side of the cavity 111 is open to form an opening 112. The cross-sectional shape of the opening 112 is the same as the cross-sectional shape of the cavity 111. The EPE member 12 is disposed in the cavity 111, fits with the inner wall of the cavity 111, and the EPE member 12 is fixed in the cavity 111 through interference fit to achieve a fixed connection with the foam member 11.

[0029] Among them, the foam member 11 can be a polystyrene foam member, which has characteristics such as strong heat preservation effect, light weight, and high strength. By setting the foam member 11 as a polystyrene foam member, not only can the weight of the foam member 11 be reduced, the weight of the packaging structure 10 be reduced, the structural strength of the packaging structure 10 be improved, and the protection effect on the air conditioner indoor unit 20 be enhanced, but also it is convenient for molding and the production difficulty is reduced.

[0030] Among them, the EPE member 12 is a polyethylene foam member. The EPE member 12 has good softness and good buffering performance, has a good sound insulation and shock absorption effect, and the flame retardant performance of the EPE member 12 is good, so that good buffering and protection performance can be provided for the packaged air conditioner indoor unit 20.

[0031] In this embodiment, the packaging structure 10 includes the foam member 11 and the EPE member 12, and the EPE member 12 is disposed in the foam member 11. The foam member 11 has a relatively high structural strength and can provide a good supporting effect for the packaged air conditioner indoor unit 20. The EPE member 12 disposed in the foam member 11 has good buffering performance. When the air conditioner indoor unit 20 is in operation, the EPE member 12 can effectively buffer the vibration during transportation and the impact force during dropping, effectively protect the internal component structure of the air conditioner indoor unit 20, and reduce the probability of abnormality of the air conditioner indoor unit 20 caused by improper transportation.

[0032] Moreover, in this embodiment, by making the EPE part 12 in interference fit with the foam part 11, the fixed connection between the EPE part 12 and the foam part 11 can be achieved, the assembly efficiency between the EPE part 12 and the foam part 11 can be improved, and the assembly cost can be reduced.

[0033] According to the packaging structure 10 of the embodiment of the present utility model, by making the EPE part 12 in interference fit within the foam part 11 to form the packaging structure 10, the buffering performance of the packaging structure 10 can be improved on the premise of ensuring the structural strength of the packaging structure 10, and the interference fit can also improve the assembly efficiency of the packaging structure 10 and reduce the cost.

[0034] In an embodiment of the present utility model, the interference amount between the EPE part 12 and the inner wall of the cavity 111 is 2 mm - 4 mm. That is to say, the size of the EPE part 12 is larger than the size of the inner wall of the cavity 111, and the interference amount between the EPE part 12 and the inner wall of the cavity 111 is greater than or equal to 2 mm and less than or equal to 4 mm. Thus, both the fixed connection between the EPE part 12 and the foam part 11 can be achieved, and it is also convenient to install the EPE part 12 into the cavity 111, improving the assembly efficiency.

[0035] For example, the interference amount between the EPE part 12 and the inner wall of the cavity 111 can be 2 mm, 2.5 mm, 3 mm, 3.5 mm or 4 mm, etc.

[0036] As Figure 1 shown, the EPE part 12 is fitted within the cavity 111. In the up and down direction, the height of the EPE part 12 is greater than the height of the cavity 111, and the difference between the height of the EPE part 12 and the height of the cavity 111 is greater than or equal to 2 mm and less than or equal to 4 mm; and / or, in the front and back direction, the width of the EPE part 12 is greater than the width of the cavity 111, and the difference between the width of the EPE part 12 and the width of the cavity 111 is greater than or equal to 2 mm and less than or equal to 4 mm.

[0037] In an embodiment of the present utility model, the EPE part 12 may include at least one cotton board, and at least part of the peripheral surface of the cotton board is in interference fit with the inner wall of the cavity 111.

[0038] That is to say, the EPE part 12 may only include one cotton board, that is, the EPE part 12 itself is in the shape of a plate body. The EPE part 12 may also include two, three, four, five, six or more cotton boards, and the EPE part 12 is composed of a combination of multiple cotton boards. For example, a structure adapted to the cavity 111 can be formed by combining multiple cotton boards, such as the EPE part 12 being formed into a box body structure with one side open.

[0039] Since the pearl cotton is not easy to be formed, in this embodiment, the pearl cotton piece 12 is composed of a cotton board in the shape of a plate body, which can simplify the structure of the pearl cotton piece 12 and facilitate the processing and forming of the pearl cotton piece 12 on the premise of ensuring the buffering performance of the packaging structure 10.

[0040] When the cotton board is fitted into the cavity 111, the cotton board can be in interference fit with the inner wall of the cavity 111 through a part of its peripheral surface. For example, the cotton board is a vertically arranged plate body. Among them, the cotton board can be in interference fit with the inner wall of the cavity 111 only in the up and down directions, while in clearance fit with the inner wall of the cavity 111 on the side surfaces in the front and back directions; the cotton board can also be in interference fit with the inner wall of the cavity 111 only in the front and back directions, while in clearance fit with the inner wall of the cavity 111 on the side surfaces in the up and down directions. Thus, the assembly of the cotton board can be facilitated and the assembly difficulty of the cotton board can be reduced.

[0041] Of course, the cotton board can also be in interference fit with the inner wall of the cavity 111 through all its peripheral surfaces. For example, the cotton board is a vertically arranged plate body, and the cotton board can be in interference fit with the inner wall of the cavity 111 in both the up and down directions and the front and back directions. In this way, the reliability of the fixation between the cotton board and the foam piece 11 can be improved.

[0042] In an embodiment of the present utility model, the thickness of the cotton board can be 35mm - 40mm. For example, the thickness of the cotton board can be 35mm, 36mm, 37mm, 38mm, 39mm or 40mm.

[0043] It should be noted that when the thickness of the cotton board is small, the cotton board does not have enough thickness and cannot provide enough buffering capacity, which affects the vibration reduction effect on the air conditioner indoor unit 20. When the thickness of the cotton board is large, on the one hand, the cotton board will occupy more space in the foam piece 11, increasing the size of the packaging structure 10. On the other hand, it will cause insufficient structural strength of the packaging structure 10 and is easy to be damaged.

[0044] In this embodiment, by setting the thickness of the cotton board between 35mm - 40mm, the structural strength of the packaging structure 10 can be ensured on the premise of meeting the vibration reduction and buffering functions, and the size of the packaging structure 10 can be within a suitable range.

[0045] In an embodiment of the present utility model, the pearl cotton piece 12 has a cotton board, and the cotton board is arranged on the bottom wall of the cavity 111 opposite to the opening 112.

[0046] For example Figure 2 As shown, the foam piece 11 forms a cavity 111 that is open on the left side. The contour of the cotton board is the same as the cross-sectional shape of the cavity 111 perpendicular to the left and right directions. The cotton board is loaded into the cavity 111 from the opening 112 on the left side, and the right surface of the cotton board is attached to the bottom wall of the cavity 111 (i.e., the right inner wall of the cavity 111). The peripheral side surface of the cotton board abuts against the peripheral wall surface of the cavity 111.

[0047] In this embodiment, by making the EPE member 12 include only one cotton board, the number of cotton boards can be reduced, and the cost can be lowered. In addition, since components such as the motor of the air conditioner indoor unit 20 are arranged at both ends in the length direction, when the air conditioner indoor unit 20 is installed into the cavity 111 of the installation structure, the position of the air conditioner indoor unit 20 where the motor is provided can extend into the cavity 111. At the same time, the cotton board can provide vibration damping and buffering for the air conditioner indoor unit 20 at the end faces at both ends in the length direction of the air conditioner indoor unit 20. In this way, the motor can be protected to the greatest extent, and the vibration impact on the motor during the transportation or dropping of the air conditioner indoor unit 20 can be reduced, and the probability of the motor generating abnormal noise can be lowered.

[0048] In an embodiment of the present utility model, the cross section of the cavity 111 is a rectangle with chamfered corners, and the shape of the cotton board is adapted to the cross section of the cavity 111. Thus, the shape of the cavity 111 and the shape of the cotton board can be adapted to the cross-sectional shape of the air conditioner indoor unit 20, which can facilitate the installation of the air conditioner indoor unit 20, and can also facilitate the effective elastic support of the end face of the air conditioner indoor unit 20 by the cotton board, improving the support and elastic buffering effect on the air conditioner indoor unit 20.

[0049] For example Figure 2 As shown, in the projection plane perpendicular to the left-right direction, the projection of the cavity 111 is a pentagon shape formed by cutting off a corner from a rectangle, and the projection of the cotton board is also a pentagon shape formed by cutting off a corner from a rectangle, and the projection of the cavity 111 is similar to the projection of the cotton board.

[0050] In an embodiment of the present utility model, in the direction from the bottom wall of the cavity 111 towards the opening 112, the cross-sectional dimension of the opening 112 gradually increases. For example Figure 2 As shown, in the direction from right to left, the inner wall of the opening 112 is formed as an inclined surface extending outward away from the center of the opening 112. In other words, the inner wall shape of the opening 112 is a conical surface. In this way, when the EPE member 12 is installed into the cavity 111, the inner wall of the opening 112 can play a role in positioning and guiding the EPE member 12, improving the assembly efficiency.

[0051] Furthermore, the end face dimension of the end of the opening 112 facing away from the bottom wall of the cavity 111 is greater than or equal to the cross-sectional dimension of the cotton board of the EPE member 12. Thus, it is beneficial to install the cotton board into the opening 112, improving the assembly efficiency.

[0052] Among them, a chamfer can be provided at the connection position between the inner wall of the cavity 111 and the outer surface of the foam member 11 to form an opening 112 with a gradually increasing cross-sectional dimension. In this way, the processing and forming of the opening 112 can be facilitated, and the processing difficulty can be reduced. Further, the angle of the chamfer can be greater than or equal to 30° and less than or equal to 60°, which can further facilitate the processing and forming. For example, the chamfer between the inner wall of the cavity 111 and the outer surface of the foam member 11 can be 35°, 45°, 55°, etc.

[0053] In an embodiment of the present utility model, a foolproof groove 113 for indicating the position of the foam member 11 is formed on the outer surface of the foam member 11. For example, the outer contour shape of the foam member 11 is a cuboid shape, and one side of the foam member 11 is open in the left-right direction. Among them, a foolproof groove 113 can be formed on one side surface of the foam member 11 in the up-down direction to indicate the position of the foam member 11 in the up-down direction, prevent the foam member 11 from being installed reversely in the up-down direction, and improve the assembly efficiency; a foolproof groove 113 can also be formed on one side surface of the foam member 11 in the front-back direction to indicate the position of the foam member 11 in the front-back direction, prevent the foam member 11 from being placed reversely in the front-back direction, and improve the assembly efficiency.

[0054] Among them, in order to further distinguish and indicate the foolproof grooves 113 in different directions, the shapes of the foolproof grooves 113 can be different in different directions. For example, the foolproof groove 113 formed on one side surface in the up-down direction can be a rectangular groove, and the foolproof groove 113 formed on one side surface of the foam member 11 in the front-back direction can be a triangle. In this way, the foolproof effect of the foam member 11 can be further improved, and the assembly efficiency can be further improved.

[0055] Further, the foolproof groove 113 can be formed on one side edge of the foam member 11 in the first direction that is away from the opening 112 and penetrate through one side edge of the foam member 11 that is away from the groove. In this way, the processing of the foolproof groove 113 can be facilitated.

[0056] In an embodiment of the present utility model, a jack 114 is formed on the foam member 11, and the jack 114 is configured to be suitable for inserting a remote controller. When packing and packaging the air conditioner indoor unit 20, the remote controller can be inserted into the jack 114 to avoid loss of the remote controller.

[0057] Among them, the jack 114 and the opening 112 are formed on the same side surface of the foam member 11. For example Figure 2 As shown, both the jack 114 and the opening 112 are formed on the left side surface of the foam member 11, and the jack 114 is located at the rectangular chamfer position of the cavity 111. In this way, the space utilization rate of the foam member 11 can be improved, and the space occupation can be reduced.

[0058] In an embodiment of the present utility model, the number of foam members 11 is two, and the two foam members 11 are adapted to be symmetrically arranged at both ends in the length direction of the air conditioner indoor unit 20. The EPE members 12 correspond to the foam members 11 one by one. In this way, the left and right ends of the air conditioner indoor unit 20 can be respectively inserted into the cavities 111 of the two packaging structures 10. Thus, it is convenient to package the air conditioner indoor unit 20, and the support and buffering effects on the air conditioner indoor unit 20 can also be improved.

[0059] Next, reference will be made to Figures 1 - 4 describe the packaging structure 10 according to a specific embodiment of the present utility model.

[0060] Referring to Figure 1 , the packaging structure 10 includes two foam members 11 and two EPE members 12. The two foam members 11 are arranged symmetrically left and right. The two foam members 11 form cavities 111 with opposite openings 112. The cross-section of the cavity 111 is a rectangular shape with a notch. The EPE member 12 is a plate-shaped cotton board perpendicular to the left-right direction, and the shape of the cotton board is adapted to the cross-section of the cavity 111. The two cotton boards are respectively arranged at the bottom wall positions of the cavities 111 of the two foam members 11. The thickness of the cotton board is 35 mm - 45 mm. The peripheral surface of the cotton board is in interference fit with the inner wall of the cavity 111, and the interference amount is 3 mm.

[0061] Among them, for the foam member 11 of the packaging structure 10 in this embodiment, the depth of the cavity 111 in the left-right direction is deepened on the basis of the original foam cushion, and an EPE member 12 is nested inside the cavity 111, and then it is fixed in the foam member 11 by interference fit, and glue or heat ironing is not required. Thus, the problem of insufficient buffering of the foam cushion can be solved, so as to better protect the internal structural parts and motors of the product, and solve the problem that the motor of the air conditioner indoor unit 20 is prone to generate abnormal noises after being dropped during transportation. By adopting the interference fit method, the efficiency is improved and the cost is saved.
