Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts transportation, in particular to a packaging piece for a back door inner plate. Background Art

[0002] At present, in the process of automobile assembly, parts need to be centrally packaged after production, and then transported to the assembly plant for assembly production. During the packaging and transportation of parts, in order to avoid collision of parts, parts packaging components need to be used. Especially when producing domestically and assembling overseas, the distance of parts packaging and transportation is long and the time is long. Therefore, it is necessary to consider the transportation cost and packaging and transportation effect to reduce parts loss.

[0003] The back door inner panel is a part of automobile assembly. Currently, its main packaging form is a wooden or paper structure. The above structure has the problems of poor shock absorption, loose fixation, and high cost, and is not suitable for long-distance transportation. Therefore, the utility model designs a packaging piece for the back door inner panel. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a packing piece for a back door inner panel.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A packaging piece for a back door inner panel, comprising a foam body made of EPS material, comprising multiple foam layers, each layer of the foam body being connected to no less than two foam bodies, a cavity being provided in the foam body, a through opening being provided in the middle of the cavity, a plurality of protrusions being provided on the upper side of the foam body, a plurality of grooves cooperating with the protrusions being provided on the lower side of the foam body, so that positioning is achieved by the cooperation of the protrusions and the grooves when the multiple foam layers are stacked, and a plurality of material reduction cavities being provided in the foam body.

[0007] Preferably, observation holes are provided in the middle of both sides of the foam body, and the observation holes on both sides pass through the mold cavity and extend to the through-opening.

[0008] Preferably, the plurality of material reduction cavities are respectively distributed on the lower end surface of the foam body and are arranged in a ring shape along the outer edge of the through-opening.

[0009] Preferably, the protrusions are arranged at the four corners of the foam body, and two protrusions are arranged on two intersecting edges of each corner of the foam body.

[0010] Preferably, an oil leakage hole is provided in the mold cavity, and the oil leakage hole passes through the bottom surface of the foam body.

[0011] Preferably, the tops and bottoms of the multiple foam layers are connected and wrapped by paper sleeves, and the paper sleeve at the bottom is connected to a base.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] The packaging box of the back door inner panel is made of EPS material. Large-scale packaging and transportation are achieved through multiple foam layers and multiple foam bodies in each layer, which improves the transportation efficiency of parts. At the same time, each foam body reduces the foam volume through multiple material reduction cavities and through-holes, which can greatly reduce the transportation cost. Empty package transportation is avoided by setting up lookout holes, and lubricating oil accumulation is avoided by setting up oil leakage holes, so as to better ensure the transportation effect.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] like Figure 1-3 As shown, a packaging piece for a back door inner panel includes a foam body 1 made of EPS material, including multiple foam layers, each layer of foam body 1 is connected to no less than two foam bodies 1, a cavity 2 is opened in each foam body 1, a through hole 3 is penetrated in the middle of the cavity 2, and the through hole 3 penetrates the bottom of the foam body 1, so that the back door inner panel is fixed in a manner that is tightly fitted and limited to the annular cavity 2, a plurality of protrusions 4 are respectively provided on the upper side of the foam body 1, and a plurality of grooves 5 cooperating with the protrusions 4 are respectively provided on the lower side of the foam body 1, so that vertical positioning is achieved through the cooperation of the protrusions 4 and the grooves 5 when the multiple foam layers are stacked, and a plurality of material reduction cavities 6 are opened in the foam body 1 to reduce the volume of the foam body 1, thereby reducing the packaging cost.

[0020] Lookout holes 7 are provided in the middle of both sides of the foam body 1, and the lookout holes 7 on both sides pass through the cavity 2 and extend to the through-port 3. The advantage of this is that the interior of the cavity 2 of the foam body 1 can be effectively penetrated, thereby avoiding the problem of empty packages. Multiple material reduction cavities 6 are respectively distributed on the lower end surface of the foam body 1 and are arranged in a ring along the outer edge of the through-port 3. The protrusions 4 are arranged at the four corners of the foam body 1, and the two intersecting edges of each corner of the foam body 1 are provided with two protrusions 4, which improves the accuracy of the protrusions 4 and the grooves 5 when limiting.
