Description

Technical Field

[0001] This utility model relates to the field of logistics packaging, specifically to a packaging box for transporting the rear door of a car. Background Technology

[0002] In some special cases, the production of automotive parts and the assembly of complete vehicles are not in the same factory. In such cases, the automotive parts need to be transported to the factory where the complete vehicles are assembled after they are produced.

[0003] Chinese patent number 202120584250.X discloses a car rear door packaging box. This packaging box includes a base and multiple packaging boxes arranged along the length of the base. The upper end of each packaging box has a material-reducing hole, and the upper surface of each packaging box has a fastening strip with multiple fastening blocks fixed to it. The fastening blocks are at least partially engaged in the material-reducing hole. Locking straps are fixed to both ends of the fastening strip. A locking mechanism is provided on the base, and the locking straps are at least partially engaged with the locking mechanism. The car rear door is fixed by the base and corresponding slots on the packaging boxes located on both sides of the base. While this method effectively secures the car rear door, it requires the base to cooperate with two packaging boxes. Since the base and packaging boxes have different mechanisms, two types of components need to be designed and manufactured separately, resulting in high equipment development and manufacturing costs, and a cumbersome construction process. Utility Model Content

[0004] The purpose of this utility model is to provide a packaging box for transporting car rear doors. This packaging box uses packaging components to accommodate car rear doors, and multiple car rear doors can be packaged and accommodated by stacking multiple packaging components along the height direction.

[0005] To achieve the above objectives, this utility model provides a packaging box for transporting the rear door of a car, comprising a tray stacked from bottom to top, a calcium plastic board at the bottom, multiple packaging components, and a calcium plastic board at the top;

[0006] The packaging includes a packaging body, a packaging cavity, a pressing surface, a limiting block, and a limiting hole that mates with the limiting block. The limiting block and the limiting hole are located on the upper and lower surfaces of the packaging body, respectively. The packaging cavity and the pressing surface are located on the upper and lower parts of the packaging body, respectively. The rear door of the car is placed in the packaging cavity, and the pressing surface of the upper packaging mates with the rear door of the car inside the lower packaging.

[0007] Preferably, the packaging has two packaging acupoints.

[0008] Preferably, the two acupoints on the packaging are arranged in a centrally symmetrical distribution.

[0009] Preferably, the lower part of the packaging body is provided with staggered first and second reinforcing beams, and the first and second reinforcing beams intersect to form a weight-reducing groove.

[0010] Preferably, the first reinforcing beam and the second reinforcing beam are parallel to the long side and the short side of the package body, respectively.

[0011] Preferably, at least two limiting blocks are provided, and two of the multiple limiting blocks are respectively provided at two opposite corners of the packaging body.

[0012] Preferably, the sidewalls of the limiting hole are configured as intersecting first and second reinforcing beams.

[0013] Preferably, the diagonally opposite limiting block is provided with a chamfered surface, and the sidewall of the limiting hole is provided with a reinforcing block corresponding to the chamfered surface. The reinforcing block is connected to the first reinforcing beam and the second reinforcing beam as a whole.

[0014] Preferably, the positions where the first and second reinforcing beams fit against the rear door of the vehicle form a pressing surface.

[0015] Preferably, the packaging body is provided with multiple handles.

[0016] According to the above technical solution, the rear door of the car is placed in the packaging cavity of this utility model. The surface of the packaging cavity is set as a curved surface that conforms to the shape of the packaging surface of the rear door. After placement, the surface of the rear door fits into the surface of the packaging cavity, thus realizing the accommodation of the rear door by the car rear door transportation packaging box.

[0017] Multiple packages can be stacked in the height direction through the cooperation of limiting blocks and limiting holes. The limiting blocks and limiting holes are located on the upper and lower surfaces of the packages, respectively. The limiting block of the lower package cooperates with the limiting hole of the upper package, thereby limiting the position of two adjacent packages.

[0018] After the rear door of the car is placed in the packaging cavity, the pressing surface of the upper packaging can cooperate with the non-packaging surface of the rear door to protect the non-packaging surface. At the same time, the rear door inside the upper packaging has a certain weight. Under the weight of the upper packaging, it can apply pressure to the rear door below through the pressing surface. During transportation, this pressure can ensure the stability of the rear door during transportation.

[0019] Preferably, when two adjacent packages are fitted together, the upper package and the lower package can fit together to completely cover the rear door of the car, thus improving the protection of the car door during transportation.

[0020] The two calcium plastic boards located at the top and bottom serve to prevent dust and collect oil. The lower part of the pallet is designed in a crisscross shape to facilitate forklift operation.

[0021] Therefore, when using this car rear door transport packaging box, only one type of packaging unit is needed to accommodate the car rear door. Moreover, multiple packaging units can be stacked vertically to accommodate even more car rear doors. Thus, only one type of packaging unit needs to be produced, making both production and use very simple.

[0022] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0037] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0038] In this utility model, unless otherwise stated, directional terms such as "upper surface," "lower surface," "upper part," "lower part," "above," "below," "parallel," and "vertical" contained in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the terminology.

[0039] See Figure 1 The aforementioned packaging box for transporting the rear door of a car includes a pallet 1 stacked from bottom to top, a calcium plastic board 2 located at the bottom, multiple packaging components, and a calcium plastic board 2 located at the top;

[0040] The packaging includes a packaging body 41, a packaging cavity 42, a pressing surface 43, a limiting block 5, and a limiting hole 6 that mates with the limiting block 5. The limiting block 5 and the limiting hole 6 are located on the upper and lower surfaces of the packaging body 41, respectively. The packaging cavity 42 and the pressing surface 43 are located on the upper and lower parts of the packaging body 41, respectively. The rear door of the car is placed in the packaging cavity 42. The pressing surface 43 of the upper packaging mates with the non-packaging surface of the rear door of the car inside the lower packaging.

[0041] By implementing the above technical solution, the rear door of the car is placed in the packaging cavity 42. The surface of the packaging cavity 42 is set as a curved surface that conforms to the shape of the packaging surface of the rear door of the car. After placement, the surface of the rear door of the car fits into the surface of the packaging cavity 42, thus realizing the accommodation of the rear door of the car in the packaging box for transporting the rear door.

[0042] Multiple packages can be stacked in the height direction by the cooperation of limiting block 5 and limiting hole 6. The limiting block 5 and limiting hole 6 are located on the upper and lower surfaces of the packages, respectively. The limiting block 5 of the lower package cooperates with the limiting hole 6 of the upper package, thereby limiting the position of two adjacent packages.

[0043] After the rear door of the car is placed in the packaging cavity 42, the pressing surface 43 of the upper packaging can cooperate with the non-packaging surface of the rear door to protect the non-packaging surface. At the same time, the rear door of the car inside the upper packaging has a certain weight. Under the action of the weight of the upper packaging, pressure can be applied to the rear door of the car below through the pressing surface 43. During transportation, this pressure can ensure the stability of the rear door during transportation.

[0044] Preferably, such as Figure 5As shown, when two adjacent packages are put together, the upper package and the lower package can fit together to completely cover the rear door of the car, thus improving the protection of the rear door during transportation.

[0045] The two calcium plastic boards 2, located at the top and bottom respectively, serve to prevent dust and collect oil. The lower part of the pallet is designed in a crisscross shape to facilitate forklift operation.

[0046] Therefore, when using this car rear door transport packaging box, only one type of packaging unit is needed to accommodate the car rear door. Moreover, multiple packaging units can be stacked vertically to accommodate even more car rear doors. Thus, only one type of packaging unit needs to be produced, making both production and use very simple.

[0047] In this embodiment, preferably, the packaging has two packaging acupoints 42.

[0048] Each package has two packaging slots 42, which can accommodate two car rear doors at the same time. Preferably, the left and right car rear doors can be put into one package at the same time, which is beneficial for installation at the destination.

[0049] In this embodiment, preferably, the two packaging acupoints 42 are arranged in a centrally symmetrical distribution.

[0050] The upper part of the car rear door has a cavity for installing the door glass, and the lower part is a sheet metal part. Therefore, there is a large weight difference between the upper and lower parts of the car rear door. By setting two packaging holes 42 symmetrically distributed in the center, the weight distribution of the two car rear doors on the packaging body 41 is more uniform. This makes the overall weight distribution more reasonable after multiple packaging boxes are stacked, and increases the stability of the car rear door transportation packaging box during transportation.

[0051] In one embodiment, the two short end faces of the packaging body 41 are provided with distinguishing marks 11 for differentiating the left and right doors. Corresponding to different distinguishing marks 11, the operator can easily distinguish which packaging cavity 2 the left and right rear doors of the car are located in, which can effectively improve the work efficiency of packaging and destination assembly.

[0052] In one embodiment, a distinguishing mark 11 is provided on one side of the packaging body 41, while no distinguishing mark 11 is provided on the other side of the packaging body 41. In this way, on-site operators can easily distinguish between the two packaging acupoints 2. It can also reduce the complexity of using the distinguishing mark 11.

[0053] More preferably, the distinguishing mark 11 is set as a recessed structure. From the perspective of cost saving, setting the distinguishing mark 11 as a recessed structure can not only save the amount of foam material used, but also the recessed structure can be directly set on the production mold without the need for additional processing steps for the distinguishing mark 11, thus reducing the processing steps to a certain extent.

[0054] In this embodiment, preferably, the lower part of the packaging body 41 is provided with staggered first reinforcing beams 45 and second reinforcing beams 46, and the first reinforcing beams 45 and second reinforcing beams 46 intersect to form a weight-reducing groove 47.

[0055] By setting a first reinforcing beam 45 and a second reinforcing beam 46 to ensure the structural strength of the packaging body 41, the first reinforcing beam 45 and the second reinforcing beam 46 intersect to form a weight-reducing groove 47. Therefore, the side of the packaging body 41 facing away from the rear door of the car includes many inwardly recessed weight-reducing grooves 47. By setting these grooves, the amount of material used for the packaging can be significantly reduced, thereby reducing the material cost of the packaging. At the same time, reliable weight reduction can be achieved, facilitating transportation.

[0056] Preferably, the side of the first reinforcing beam 45 and the second reinforcing beam 46 that contacts the rear door of the car is provided with a curved surface that conforms to the shape of the rear door surface. When the upper packaging body 41 covers the lower packaging body 41, the first reinforcing beam 45 and the second reinforcing beam 46 can fit well against the non-packaging surface of the rear door of the car. While achieving reliable stacking, they can also limit the rear door of the car located below, ensuring stability during the transportation process.

[0057] In this embodiment, preferably, the first reinforcing beam 45 and the second reinforcing beam 46 are parallel to the long side and the short side of the packaging body 41, respectively.

[0058] The first reinforcing beam 45 and the second reinforcing beam 46 are parallel to the long side and the short side of the packaging body 41, respectively. Therefore, the packaging body can also be set with the first reinforcing beam 45 and the second reinforcing beam 46 around its perimeter. In this way, the first reinforcing beam 45 and the second reinforcing beam 46 can be arranged to the maximum extent, further reducing the number of the first reinforcing beam 45 and the second reinforcing beam 46 and achieving the purpose of saving materials.

[0059] In this embodiment, preferably, at least two limiting blocks 5 are provided, and two of the multiple limiting blocks 5 are respectively provided at two opposite corners of the packaging body 41.

[0060] By fixing the diagonal, the relative position of two adjacent packages can be effectively controlled. Therefore, by setting two limiting blocks 5 at two opposite corners of the package body 41, the position of two adjacent packages can be limited along the diagonal.

[0061] From the perspective of saving space in transportation, the packaging needs to be set into a relatively regular shape, usually a rectangle. This will be very beneficial for the close arrangement of multiple car rear door transport packaging boxes in a limited space, thus effectively saving space.

[0062] Preferably, four limiting blocks 5 are provided, and the four limiting blocks 5 are positioned as close as possible to the four corners of the package body 41.

[0063] Since the limiting block 5 needs to play a role in the relative positioning of the upper and lower packaging pieces, the limiting block 5 needs to have a certain strength. The cross-sectional area and height of the limiting block 5 need to be designed in accordance with the strength requirements and positioning reliability.

[0064] Preferably, due to the limited space on the surface of the packaging body 41, the cross-sectional shape of the limiting block 5 can be set differently, but the height of the limiting block 5 needs to be set to the same.

[0065] By cooperating with multiple limiting blocks 5 and limiting holes 6, the two adjacent packages no longer have the degree of freedom of relative movement. That is, by cooperating with multiple limiting blocks 5 and limiting holes 6, the two adjacent packages are limited in both the X and Y directions, which improves the stability of the packages after stacking. During transportation, the relative position between the two adjacent packages will not change.

[0066] Preferably, there are 6 limiting blocks 5. Four limiting blocks 5 are located at the four corners of the packaging body 41, and the other two limiting blocks 5 are located on the two opposite long sides, and are set at positions as far apart as possible from each other according to the actual space.

[0067] In this embodiment, preferably, the sidewall of the limiting hole 6 is configured as an intersecting first reinforcing beam 45 and a second reinforcing beam 46.

[0068] The intersection of the first reinforcing beam 45 and the second reinforcing beam 46 is aligned with the position of the limiting hole 6. The cooperation between the first reinforcing beam 45, the second reinforcing beam 46, and the limiting block 5 ensures reliable positioning of two adjacent packages. Setting the limiting hole 6 to be shared with the weight-reducing groove 47 reduces the number of structural components in the automotive rear door transport packaging box, while also lowering the complexity of the mold design.

[0069] In this embodiment, preferably, the diagonally opposite limiting block 5 is provided with a chamfered surface 51, and the sidewall of the limiting hole 6 is provided with a reinforcing block 61 corresponding to the chamfered surface 51 of the limiting block 5. The reinforcing block 61 is connected to the first reinforcing beam 45 and the second reinforcing beam 46 as a whole.

[0070] like Figure 2-4As shown, the limiting block 5 is set as a cuboid with a chamfered surface. The side wall of the limiting hole 6 is provided with a reinforcing block 61 corresponding to the chamfered surface 51 of the limiting block 5. The reinforcing block 61 is connected to the first reinforcing beam 45 and the second reinforcing beam 46 as a whole, which can improve the structural strength of the first reinforcing beam 45 and the second reinforcing beam 46 at the connection.

[0071] Preferably, the reinforcing block 61 is disposed at the corner of the package to improve the structural strength of the package at the corner.

[0072] The packaging boxes used for transporting car rear doors have strength requirements for the corners of the packaging. Specifically, during the corner drop test, only localized compression is allowed at the corners of the packaging body 41. By adding reinforcing blocks 61 to the first reinforcing beam 45 and the second reinforcing beam 46 at the corner, the structural strength of the packaging body 41 at that corner can be significantly improved, resulting in better performance of the packaging body 41 in the corner drop test.

[0073] In this embodiment, preferably, the first reinforcing beam 45 and the second reinforcing beam 46 form a pressing surface 43 at the position where they fit against the rear door of the car.

[0074] After the rear door of the car is placed in the packaging cavity 42, its height may exceed the upper surface of the packaging. In this case, the bottom of the upper packaging needs to be provided with a groove to accommodate the part of the rear door that is higher than the packaging. Preferably, the positions where the first reinforcing beam 45 and the second reinforcing beam 46 fit against the rear door form a pressing surface 43. This pressing surface 43 cooperates with the non-packaging surface of the rear door to form a curved surface that conforms to the shape of the non-packaging surface of the rear door, thereby achieving better accommodation of the rear door.

[0075] By setting a pressure surface 43 at the bottom of the packaging, the thickness of the packaging can also be effectively reduced, resulting in a smaller height for the car rear door transport packaging box, thereby improving the efficiency of space utilization.

[0076] Preferably, the pressing surface 43 and the packaging cavity 42 are connected through a receiving hole. The solid portion between the pressing surface 43 and the packaging cavity 42 is used to isolate two adjacent rear doors of the car, protecting the rear doors during transportation. The main body of the rear door is located within the receiving hole, while the solid portion around the receiving hole supports the outer edge of the rear door. The portion of the rear door that is higher than the main body 41 of the packaging component cooperates with the pressing surface 43 above and is received within the upper packaging component. The portion of the rear door that is lower than the main body 41 of the packaging component is located in the packaging cavity 42 and is received within the lower packaging component. Therefore, by providing the receiving hole, the thickness of the car rear door transport packaging box is reduced, each car rear door can be stored by fitting two adjacent car rear door transport packaging boxes together, and the material usage of the car rear door transport packaging box can be reduced by providing the receiving hole, thus reducing material costs.

[0077] In this embodiment, preferably, the packaging body 41 is provided with a plurality of handles 7.

[0078] To facilitate staff in handling the package, a handle 7 is provided at the bottom of the package body 41, allowing staff to easily grasp the package.

[0079] Preferably, multiple handles 7 can be provided to facilitate workers to grasp the packaged items from any angle.

[0080] To ensure the structural strength of the packaging, the depth of the handle 7 should not be too large; a depth that allows a finger to be inserted is sufficient to meet the usage requirements.

[0081] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0082] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0083] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
