The invention provides a packaging structure which is used for packaging household appliances; in this embodiment, the packaging structure is specifically used for packaging an air conditioner outdoor unit (or an air conditioner integrated unit), however, in other embodiments, the packaging structure may also be used for packaging household appliances such as a washing machine, a dehumidifier, etc., and the design is not limited thereto.
In an embodiment of the present invention, referring to fig. 1 to 7 and fig. 9 and 12, the package structure includes:
the package body 1 is provided with a first surface 11 and a second surface 12 which are oppositely arranged, the first surface 11 is used for being matched and installed by the air conditioner outdoor unit 3, and a plurality of protruding points 123 are convexly arranged on the second surface 12; and
the protective film layer 2 is covered on the second surface 12 and is integrally arranged with the package body 1; a concave pit 211a is formed on the inner surface of the protective film 2 corresponding to each convex point 123, and a convex corresponding to each concave pit 211a is formed on the outer surface of the protective film, and the convex points 123 are adapted to be covered on the protective film 2 through the concave pits 211a.
In this embodiment, the package body 1 is a foam member, and it can be appreciated that the foam structure has better buffering performance, which is beneficial to protecting the air conditioner outdoor unit 3, and of course, in other embodiments, the package body 1 may also have other structures with better anti-seismic performance. In addition, referring to fig. 1, in the present embodiment, the foam member is a foam board packaged at the bottom of the air-conditioning outdoor unit 3, and the packaging structure of the air-conditioning outdoor unit 3 further includes a packaging box 4 adapted to fit the air-conditioning outdoor unit 3 and the foam board from top to bottom, it can be understood that the first surface 11 of the foam board supports the air-conditioning outdoor unit 3, the second surface 12 is exposed to the outside, and the protective film layer 2 on the second surface 12 effectively protects the foam board; of course, in other embodiments, the foam member may be packaged on top of the air conditioner outdoor unit 3 or packaged on the side of the air conditioner outdoor unit 3, which is not limited in this design.
According to the technical scheme, the second surface 12 of the package body 1 is provided with the plurality of protruding points 123 in a protruding mode, and the inner surface of the protective film layer 2 covered with the second surface 12 is provided with the concave pits 211a which are matched with the protruding points 123, so that the contact area between the protective film layer 2 and the package body 1 is effectively increased, the connection tightness between the protective film layer 2 and the package body 1 is further enhanced, and the problem that the protective film layer 2 falls off after the package structure is used for a long time is avoided.
Further, the protective film layer 2 is a plastic film layer. It can be understood that the plastic film is a widely used structure in the prior art, and has the advantages of low thickness, stable structure, easy obtainment and the like. It should be noted that the present design is not limited to this, and in other embodiments, the protective film 2 may be a silica gel film or the like. In this embodiment, the plastic film layer is a PS film, and it can be understood that, on one hand, the PS film has better waterproof performance than other films, and can effectively prevent the packaging structure from being wetted, and on the other hand, the PS film has better bonding effect with the packaging body 1, which is beneficial to ensuring the tight connection between the PS film and the packaging body 1, and avoiding the occurrence of bubbles between the plastic film and the packaging body 1, even the plastic film falling off under scraping after the packaging structure is used for a long time; of course, in other embodiments, the plastic film layer may be a PET plastic film, a PP plastic film, an ABS plastic film, or the like, which is not limited in this design.
Further, the thickness of the protective film layer 2 is 0.05mm to 1.5mm. It can be understood that the thickness of the protective film layer 2 is too small, the protective effect on the package body 1 is poor, and the thickness of the protective film layer 2 is too large, which easily causes the waste of the structure, and then increases the production cost of the package structure.
Further, the protective film layer 2 is integrally formed on the second surface 12 of the package body 1 by hot pressing. It can be understood that the hot-pressing integrated forming technology is widely applied in the prior art, has the advantages of stable connection, high production efficiency and the like, and can effectively ensure the connection tightness of the protective film layer 2 and the package body 1 and avoid the phenomena of loosening, falling and the like of the protective film layer 2 after long-term use of the package structure when applied to the technical scheme of the invention. It should be noted that the present design is not limited thereto, and in other embodiments, the protective film layer 2 may be adhered or integrally formed on the second surface 12 of the package body 1 by hydraulic pressure.
Further, referring to fig. 4 to 7, the package body 1 further has a third surface 13 connecting the peripheral edges of the first surface 11 and the second surface 12, the protective film layer 2 includes a protective film body 21 and a first folded edge portion 22 disposed on the peripheral edge of the protective film body 21, the protective film body 21 is disposed on the second surface 12, and the first folded edge portion 22 is disposed on the third surface 13. It will be appreciated that the arrangement is such that the protective film 2 better encloses the package body 1, on the one hand enhancing the stability of the connection between the two, and on the other hand, the protective film 2 also forms an effective protection for the peripheral side of the package body 1.
In this embodiment, the side edge of the first folded edge 22 facing away from the second surface 12 is flush with the connecting edge of the third surface 13 and the first surface 11, so that the first folded edge 22 completely covers the third surface 13 to better protect the package body 1; in another embodiment, the first folded edge 22 extends away from the side edge of the second surface 12, and is folded towards the first surface 11 to form a second folded edge that is disposed to cover the first surface 11, which can be understood so that the protection film layer 2 also protects the inner side surface of the package body 1 to some extent.
Further, referring to fig. 4, 6 and 10, the second surface 12 of the package body 1 is concavely provided with a plurality of material saving grooves 121, the protective film body 21 includes a first film 211 and a second film 212 connected to each other, the first film 211 is covered on the second surface 12, and the second film 212 is covered on the inner wall of the material saving groove 121. It can be understood that the material saving groove 121 is formed in the package body 1, so that the material consumption of the package body 1 can be reduced on the basis of ensuring the buffering performance of the package body 1, thereby reducing the production cost of the package structure, and the corresponding additionally-arranged material saving groove 121 is formed, and the second membrane 212 of the protective film body 21 covers the groove wall of the material saving groove 121, so that the structural strength in the material saving groove 121 is effectively ensured, and the material saving groove 121 is prevented from being deformed due to external collision. It should be noted that, the present design is not limited to this, and in other embodiments, the second surface 12 of the package body 1 is not additionally provided with a concave-convex structure, but is horizontally disposed, so as to reduce the process difficulty of the package body 1.
In this embodiment, the second surface 12 is provided with a plurality of material saving grooves 121, the middle of the first surface 11 of the package body 1 is concavely provided with a process groove 111 (the package body 1 forms supporting protrusions for supporting the outdoor unit 3 of the air conditioner on both sides of the process groove 111), the second surface 12 is provided with a first side edge 125 and a second side edge 126 oppositely arranged in a first direction (the length direction of the package body 1), and the plurality of material saving grooves 121 comprise a first material saving groove 121a near the first side edge 125 and a second material saving groove 121b near the second side edge 126. It can be appreciated that the arrangement is such that the process groove 111 and the material saving groove 121 of the package body 1 are arranged in a staggered manner, so that the package body 1 is prevented from being too thin at the position where the process groove 111 and the material saving groove 121 are overlapped in the up-down direction, and the structural strength is seriously reduced. In addition, in this embodiment, the material saving groove 121 is a cuboid groove, and the connection parts of the groove walls of the material saving groove 121 are rounded to better avoid the influence on the structural strength of the package body 1 after the groove is opened.
Further, the thickness of the second membrane 212 is smaller than the thickness of the first membrane 211. It can be appreciated that, as before, the protective film 2 is preferably covered on the second surface 12 of the package body 1 by hot-pressing and integrally forming, when the second surface 12 of the package body 1 is provided with the material saving groove 121, the mold presses the protective film 2 to bend and deform the protective film into a shape adapted to the material saving groove 121, so that the thickness of the second film 212 is necessarily smaller than that of the original film (the first film 211) after bending and stretching. It will be appreciated that the second membrane 212 includes a vertical membrane attached to the sidewall of the chute 121, and a horizontal membrane attached to the bottom wall of the chute 121, and the thickness of the vertical membrane is correspondingly smaller than that of the horizontal membrane based on the fact that the second membrane 212 is formed by bending. In addition, referring to fig. 10, in the present embodiment, the length of the vertical membrane is S3, and the value of S3 ranges from 10mm to 20mm, it is understood that if S3 is too small, the material saving effect of the material saving slot 121 is not obvious, and considering the bending and stretching forming manner of the second membrane 212, too large S3 will definitely result in too low structural strength of the second membrane 212, even damaged during bending and stretching.
Referring to fig. 5, 9 and 12, in the present embodiment, the protruding points 123 are formed on the second surface 12 outside the material saving groove 121 (formed on the first membrane 211), however, in other embodiments, the protruding points 123 may be formed partly outside the material saving groove 121, partly inside the material saving groove 121 (formed on the transverse membrane of the second membrane 212), or both inside the material saving groove 121; it will be appreciated that, as before, the protective film layer 2 is preferably formed by hot-pressing to cover the second surface 12 of the package body 1, and the protruding points 123 are added to the second surface 12, which will certainly increase the contact area between the protective film body 21 and the second surface 12, so as to better achieve heat transfer therebetween and ensure tightness of the adhesion of the protective film body 21 to the second surface 12. In this embodiment, referring to fig. 9, the protruding height of the protrusion is S2, the value range of S2 is 0.1 mm-1 mm, that is, the protruding height range of the bump 123 on the second surface 12 is 0.1 mm-1 mm, it can be understood that the protruding height of the bump 123 is too small, the effect of enhancing the adhesion of the protective film body 21 on the second surface 12 is poor, the protruding height of the bump 123 is too large, and the structural strength of the protective film body 21 adapted to the pit 211a formed by the bump 123 is poor.
In this embodiment, a plurality of bumps 123 are provided, and the plurality of bumps 123 are arranged on the second surface 12 at intervals in a single group, and a plurality of groups of pits 211a are formed on the protective film layer 2 corresponding to the plurality of groups of bumps 123. In addition, in the present embodiment, the plurality of groups of bumps 123 are arranged in a rectangular array on the second surface 12, and it can be understood that, since the contact area between the single bump 123 and the protective film body 21 and the second surface 12 is smaller, the compactness of the protective film body 21 attached to the second surface 12 is more significantly improved by arranging the plurality of bumps 123 in groups. In addition, in the present embodiment, any of the bump 123 is arranged in a circular shape, the diameter of any of the bump 123 is S1, the value range of S1 is 5 mm-15 mm, and of course, in other embodiments, any of the bump 123 may be arranged in other shapes such as regular hexagon, which is not limited in this design.
Further, referring to fig. 4, 7 and 13, a plurality of demolding grooves 122 (formed by pressing a pressing rod when demolding the package body 1) are formed in the second surface 12 of the package body 1 with the material saving groove 121 therebetween, convex portions are formed on the inner surface of the protection film body 21 corresponding to the demolding grooves 122, concave portions 211b corresponding to the convex portions are formed on the outer surface of the protection film body 21, and the convex portions of the protection film body 21 are fitted to the demolding grooves 122. It will be appreciated that this arrangement is also advantageous for achieving tightness of the application of the protective film body 21 to the second surface 12. In this embodiment, the recess depth of the recess 211b is S4, the value range of S4 is 0.1 mm-1 mm, that is, the recess depth of the demolding groove 122 on the second surface 12 is 0.1 mm-1 mm, it can be understood that the recess depth of the demolding groove 122 is too small, the effect of enhancing the adhesion of the protective film body 21 on the second surface 12 is poor, the recess depth of the demolding groove 122 is too large, and the structural strength of the concave pit 211a formed by adapting the protective film body 21 to the convex point 123 is poor.
In this embodiment, the demolding grooves 122 are provided with a plurality of demolding grooves 122, and the plurality of demolding grooves 122 are respectively arranged along the periphery of the second surface 12 at intervals, and it can be understood that the ejector rods are arranged in such a way to uniformly push against the second surface 12 of the package body 1, so that the demolding stability of the package body 1 is facilitated. In the present embodiment, the demolding groove 122 is a cylindrical groove, however, in other embodiments, the demolding groove 122 may be a rectangular groove, and the design is not limited thereto. In addition, in this embodiment, the second surface 12 of the package body 1 is further provided with a plurality of feeding grooves 124 (the package body 1 is formed to form a connecting feeding port) by forming the material saving grooves 121 and the demolding grooves 122, and the inner surface of the protective film body 21 is further adapted to be provided with the feeding grooves 124.
