Description

Technical Field

[0001] This utility model relates to the field of logistics packaging, specifically to an EPS foam packaging box for transporting automobile roofs. Background Technology

[0002] Besides its function of protecting against rain and dust, the car roof, along with other parts of the vehicle body, enhances the overall strength and torsional rigidity of the vehicle, making it an indispensable component. In some special cases, automotive parts are manufactured in separate factories from the vehicle assembly plant, and the manufactured parts need to be transported to the assembly plant. As a crucial component of the vehicle, the car roof also needs to be transported to the assembly plant for final assembly.

[0003] Chinese Patent No. 201720341838.6 discloses a packaging device for an automotive roof assembly, comprising a frame structure, which is a profile frame structure; the frame structure includes a base and a pair of side frames and a pair of end frames mounted on the base; the base and side frames are provided with protective strips on their inner sides to prevent the roof assembly from contacting the frame profile; the tops of the pair of side frames are connected by a pull rod; the side frames and end frames are mounted on the base by fasteners and are spliced ​​together by fasteners; the end of the pull rod is provided with a bent hook, which is engaged with the top of the side frame; a pressure stop is provided between the tops of the pair of end frames to prevent the roof assembly from contacting the frame profile; the end of the pressure stop is provided with a retaining plate, and the inner top of the end frame is provided with a groove adapted to the retaining plate; the protective strips and the pressure stop are both sponge strips. While this method can achieve the positioning of the car roof, the frame structure cannot provide full protection for the roof, so the roof is still at risk of being hit or scratched by foreign objects during transportation. Utility Model Content

[0004] The purpose of this utility model is to provide an EPS foam packaging box for transporting car roofs. Through the cooperation of positioning blocks and limiting grooves, the packaging boxes for transporting car roofs can be stacked. The edges of two stacked packaging boxes for transporting car roofs fit together, thus achieving reliable protection for the car roof.

[0005] To achieve the above objectives, this utility model provides an EPS foam packaging box for transporting car roofs, including a packaging box body, a supporting surface, a positioning surface, a positioning block, and a limiting groove that cooperates with the positioning block. The positioning block and the limiting groove are located on the upper and lower surfaces of the packaging box body, respectively. The supporting surface and the positioning surface are located on the upper and lower parts of the packaging box body, respectively. The supporting surface cooperates with the first surface of the car roof, and the positioning surface cooperates with the second surface of the car roof.

[0006] By using the positioning block and the limiting groove, two EPS foam packaging boxes used for transporting car roofs can be stacked, and the edges of the two packaging boxes fit together after stacking.

[0007] Preferably, the lower part of the packaging box body is provided with staggered first and second reinforcing beams, and the first and second reinforcing beams intersect to form a weight-reducing groove.

[0008] Preferably, the first reinforcing beam and the second reinforcing beam are parallel to the long side and the short side of the packaging box body, respectively.

[0009] Preferably, at least two positioning blocks are provided, and two of the multiple positioning blocks are respectively located at two opposite corners of the packaging box body.

[0010] Preferably, the sidewalls of the limiting groove are configured as intersecting first and second reinforcing beams.

[0011] Preferably, the positions where the first and second reinforcing beams fit against the vehicle roof form a positioning surface.

[0012] Preferably, the positioning surface and the package support surface are connected through a receiving hole.

[0013] Preferably, the support surface is at least partially higher than the upper surface of the packaging box body, and a retrieval gap is provided between the support surface higher than the upper surface of the packaging box body and the edge of the car roof.

[0014] According to the above technical solution, this utility model places the car roof on a supporting surface. The supporting surface has a curved surface that conforms to the shape of the first surface of the car roof, which can cooperate with the first surface of the car roof to support and accommodate it. The packaging box body has protrusions around the perimeter of the supporting surface. After the car roof is placed on the supporting surface, the packaging box body can circumferentially limit the car roof, so that the car roof will not slide horizontally after being placed on the supporting surface.

[0015] After the car roof is placed inside the packaging box used for transporting car roofs, another packaging box for transporting car roofs is placed on top of the lower one. The positioning surface of the upper packaging box mates with the second surface of the car roof, allowing the car roof to be positioned between the two adjacent packaging boxes. This minimizes the height of the packaging boxes, making efficient use of space. Furthermore, the upper packaging box can also hold a car roof. The weight of this upper car roof applies pressure to the lower one, maintaining its relative stability and ensuring stability during transport.

[0016] The relative positions of two adjacent packaging boxes used for transporting car roofs are fixed by the cooperation of positioning blocks and limiting grooves. When the positioning blocks and limiting grooves are engaged, the edges of the two adjacent packaging boxes used for transporting car roofs come into contact with each other, so that the car roof located in it can be completely wrapped around the car roof by the two packaging boxes used for transporting car roofs. The packaging box body 1 located above and below the car roof can wrap the car from both the top and bottom, so that the stacked packaging boxes used for transporting car roofs can effectively protect the car roof.

[0017] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0032] 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.

[0033] In this utility model, unless otherwise stated, directional words such as "one end," "the other end," "outer surface," "axis," "conical," and "near" 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 term.

[0034] See Figure 1-4 An EPS foam packaging box for transporting car roofs includes a packaging box body, a supporting surface, a positioning surface, a positioning block, and a limiting groove that cooperates with the positioning block. The positioning block and the limiting groove are located on the upper and lower surfaces of the packaging box body, respectively. The supporting surface and the positioning surface are located on the upper and lower parts of the packaging box body, respectively. The supporting surface cooperates with the first surface of the car roof, and the positioning surface cooperates with the second surface of the car roof.

[0035] By using the positioning block and the limiting groove, two EPS foam packaging boxes used for transporting car roofs can be stacked, and the edges of the two packaging boxes fit together after stacking.

[0036] Through the implementation of the above technical solution, the car roof is placed on the support surface 2. The support surface 2 has a curved surface that conforms to the shape of the first surface of the car roof, which can cooperate with the first surface of the car roof to support and accommodate the car roof. The packaging box body 1 has protrusions around the support surface 2. After the car roof is placed on the support surface 2, the packaging box body 1 can circumferentially limit the car roof, so that the car roof will not slide in the horizontal direction after being placed on the support surface 2.

[0037] After the car roof is placed inside the packaging box for transporting the car roof, another packaging box for transporting the car roof is placed on top of the lower packaging box. The positioning surface 3 of the upper packaging box can then mate with the second surface of the car roof, allowing the car roof to be positioned between the two adjacent packaging boxes. This minimizes the height of the packaging boxes and makes efficient use of space. Furthermore, the upper packaging box can also hold a car roof. The weight of this upper packaging box applies pressure to the lower car roof, ensuring its relative stability during transport.

[0038] The relative positions of two adjacent packaging boxes used for transporting car roofs are fixed by the cooperation of positioning block 4 and limiting groove 5. When the positioning block 4 and limiting groove 5 are engaged, the edges of the two adjacent packaging boxes used for transporting car roofs come into contact with each other, so that the car roof located therein can be completely wrapped around the car roof by the two packaging boxes used for transporting car roofs. The packaging box body 1 located above and below the car roof can wrap the car from both the top and bottom, so that the stacked packaging boxes used for transporting car roofs can effectively protect the car roof.

[0039] Preferably, the supporting surface 2 of the packaging box used for transporting the car roof is aligned with the first surface of the car roof, and its positioning surface 3 is aligned with the second surface of the car roof. In this way, after placing the first car roof, the second car roof can be rotated 180° and placed, and so on. This method can make the overall mass distribution more uniform after all the car roofs are placed, which is beneficial to the stability of the car roof during transportation.

[0040] In this embodiment, preferably, the lower part of the packaging box body 1 is provided with staggered first reinforcing beams 61 and second reinforcing beams 62, and the first reinforcing beams 61 and second reinforcing beams 62 intersect to form a weight-reducing groove 63.

[0041] By setting a first reinforcing beam 61 and a second reinforcing beam 62 to ensure the structural strength of the packaging box body 1, the first reinforcing beam 61 and the second reinforcing beam 62 intersect to form a weight-reducing groove 63. Therefore, the side of the packaging box body 1 facing away from the car roof includes many inwardly recessed weight-reducing grooves 63. By setting these grooves, the amount of material used in the packaging box body 1 can be significantly reduced, and the material cost of the packaging box body 1 can be reduced.

[0042] In this embodiment, preferably, the first reinforcing beam 61 and the second reinforcing beam 62 are parallel to the long side and the short side of the packaging box body 1, respectively.

[0043] The first reinforcing beam 61 and the second reinforcing beam 62 are parallel to the long and short sides of the packaging box body 1, respectively. Therefore, the perimeter of the packaging box body 1 can also be configured with the first reinforcing beam 61 and the second reinforcing beam 62. This method allows for the most efficient arrangement of the first reinforcing beam 61 and the second reinforcing beam 62, further reducing their number and achieving material savings. In this embodiment, preferably, at least two positioning blocks 4 are provided, with two of the multiple positioning blocks 4 positioned at opposite corners of the packaging box body 1.

[0044] By fixing the diagonal, the relative positions of two adjacent packaging box bodies 1 can be effectively controlled. Therefore, by setting two positioning blocks 4 at the two opposite corners of the packaging box body 1, the position of two adjacent packaging box bodies 1 along the diagonal can be defined.

[0045] From the perspective of saving space, the main body of the packaging box 1 needs to be set to a relatively regular shape, usually a rectangle. This will be very beneficial for the compact arrangement of the packaging boxes used for transporting car roofs in a limited space, thereby effectively saving space.

[0046] Preferably, four positioning blocks 4 are provided, and the four positioning blocks 4 are positioned as close as possible to the four corners of the packaging box body 1.

[0047] Since the positioning block 4 needs to play a role in the relative positioning of the upper and lower packaging box bodies 1, the positioning block 4 needs to have a certain strength. The cross-sectional area and height of the positioning block 4 need to be designed in accordance with the strength requirements and positioning reliability.

[0048] Preferably, due to the limited available space on the surface of the packaging box body 1, the cross-sectional shape of the positioning block 4 can be set differently, but the height of the positioning block 4 needs to be set to be the same.

[0049] By cooperating with multiple positioning blocks 4 and limiting grooves 5, the two adjacent packaging box bodies 1 no longer have the degree of freedom of relative movement. That is, by cooperating with multiple positioning blocks 4 and limiting grooves 5, the two adjacent packaging box bodies 1 are limited in the X and Y directions, which improves the stability of the packaging box bodies 1 after stacking. During transportation, the relative position between the two adjacent packaging box bodies 1 will not change.

[0050] Preferably, there are six positioning blocks 4. Four positioning blocks 4 are located at the four corners of the packaging box body 1, and the other two positioning blocks 4 are located on two opposite long sides, and are positioned as far apart as possible from each other according to the actual space.

[0051] In this embodiment, the sidewalls of the preselected limiting groove 5 are configured as intersecting first reinforcing beam 61 and second reinforcing beam 62.

[0052] The intersection of the first reinforcing beam 61 and the second reinforcing beam 62 is aligned with the position of the limiting groove 5. The cooperation between the first and second reinforcing beams 61 and the limiting block ensures reliable positioning of two adjacent packaging box bodies 1. Setting the limiting groove 5 to be shared with the weight-reducing groove 63 reduces the number of structural components in the packaging box used for transporting car roofs, and also lowers the complexity of the mold design for the packaging box used for transporting car roofs.

[0053] In this embodiment, preferably, the positioning surface 3 is formed at the position where the first reinforcing beam 61 and the second reinforcing beam 62 are attached to the car roof.

[0054] The first reinforcing beam 61 and the second reinforcing beam 62 have a curved surface that conforms to the shape of the second surface on the side that contacts the second surface of the car roof. This curved surface is set as the positioning surface 3. When the upper packaging box body 1 is placed on the lower packaging box body 1, the positioning surface 3 can fit well with the second surface of the car roof. While achieving reliable stacking, it can also limit the position of the lower car roof and ensure stability during transportation.

[0055] The car roof is placed inside the packaging box body 1. Using the weight of the car roof, the packaging box body 1 applies a certain pressure to the car roof below through the positioning surface 3. Under the action of this pressure, the car roof can be guaranteed not to move up and down.

[0056] After the car roof is placed on the support surface 2, its height will exceed the upper surface of the packaging box body 1. At this point, a groove needs to be provided at the bottom of the upper packaging box body 1 to accommodate the portion of the car roof that extends beyond the packaging box body 1. The positions where the first reinforcing beam 61 and the second reinforcing beam 62 fit against the car roof form a positioning surface 3. This positioning surface 3 has a curved surface that conforms to the shape of the second surface of the car roof, allowing it to mate with the surface of the car roof that extends beyond the packaging box body 1, thereby accommodating the portion of the car roof that extends beyond the packaging box body 1. In this way, the cooperation of two adjacent packaging boxes used for transporting the car roof effectively achieves the storage and protection of the car roof. Furthermore, by providing the positioning surface 3 at the bottom of the packaging box body 1, the thickness of the packaging box used for transporting the car roof can be effectively reduced, resulting in a smaller packaging box and improved space utilization efficiency.

[0057] In this embodiment, preferably, the positioning surface 3 and the package support surface 2 are connected through the receiving hole 11.

[0058] The receiving hole 11 is positioned corresponding to the regular curved surface of the car roof, and the solid portion between the positioning surface 3 and the supporting surface 2 is used to support and isolate two adjacent car roofs. In this way, the amount of material used can be reduced and the material cost can be lowered while providing reliable support and protection for the car roof.

[0059] Preferably, the receiving hole 11 is located in the middle of the packaging box body 1. The solid portion around the receiving hole 11 can provide reliable support for the car roof, and by setting the thickness of the solid portion, it can also effectively isolate two adjacent car roofs to avoid bumps and collisions during transportation.

[0060] In this embodiment, preferably, the support surface 2 is at least partially higher than the upper surface of the packaging box body 1, and a retrieval gap is provided between the support surface 2, which is higher than the upper surface of the packaging box body 1, and the edge of the car roof.

[0061] The support surface 2 is at least partially higher than the upper surface of the packaging box body 1. When the car roof is placed on the support surface 2, at least part of the car roof will be higher than the packaging box body 1. A retrieval gap is provided between the support surface 2, which is higher than the upper surface of the packaging box body 1, and the edge of the car roof. Therefore, a part of the operating space is reserved under the car roof through the retrieval gap. By using this operating space, the operator can operate the car roof by grabbing the edge of the car roof corresponding to the retrieval gap.

[0062] The operator grasps the car roof at the retrieval gap. Since the car roof is heavy, it is preferable that retrieval gaps be provided on both sides of the packaging box body 1. Two operators place their hands under the retrieval gaps on both sides to lift the car roof. Then the car roof can be placed on the support surface 2. After placement, the operator can easily put the car roof down. Since there is operating space on the upper surface of the packaging box body 1 corresponding to the retrieval position, the operator can easily retract their hand.

[0063] Preferably, the packaging box used for transporting the car roof is made of EPS foam in one piece.

[0064] Because EPS foam has an extremely low density, its use can reliably reduce the weight of packaging boxes used for transporting car roofs, thereby lowering transportation costs.

[0065] The packaging box used for transporting car roofs can be used to package the car roofs in the following way:

[0066] Step 1: Place tray 71 at the bottom, place calcium plastic board 72 with the opening facing up on tray 71, and place the packaging box for transporting the car roof inside calcium plastic board 72.

[0067] Step 2: Place the car roof on the support surface 2, and place the lid of the packaging box used to transport the car roof on the car roof.

[0068] Step 3: Repeat step 2 until the height of the topmost packaging box used to transport the car roof reaches the required level.

[0069] Step 4: Take calcium plastic board 72 and place it on top of the packaging box used for transporting the car roof.

[0070] Through the implementation of the above technical solution, the lower part of the tray 71 is set in a U-shape, which is convenient for forklift operation and is beneficial to the transfer of the car roof; a calcium plastic board 72 is placed below the packaging box for transporting the car roof as an oil drip tray, which can承接 the oil stains dripping from the sheet metal parts above.

[0071] The car roof is placed in the packaging box for transporting the car roof. According to the size of the packaging box, at least one roof is placed in each packaging box, and then another packaging box for transporting the car roof is stacked above, and another roof is placed. In this way, the packaging and storage of the roof are realized.

[0072] Adjacent two packaging boxes for transporting the car roof are stacked in the height direction through the cooperation of the positioning block 4 and the limiting groove 5. Preferably, the edges of the adjacent two packaging box bodies 1 are in contact with each other, so as to realize reliable protection of the car roof located therein.

[0073] Preferably, a handle 8 is provided on the packaging box body 1, and the operator can easily take the packaging box body 1 through the handle 8. In actual production, the operator needs to first take the packaging box for transporting the car roof, and determine its position through the cooperation of the positioning block 4 and the limiting groove 5 with the packaging box for transporting the car roof below, and then place the car roof.

[0074] In this embodiment, preferably, in step three, the top of the uppermost packaging box for transporting the car roof is set to be horizontal.

[0075] Setting the top of the uppermost packaging box for transporting the car roof to be horizontal is very beneficial to logistics packaging. Preferably, the uppermost packaging box for transporting the car roof can be cut along the upper surface of the packaging box body 1. It is also very easy to cut the packaging box body 1 made of EPS foam.

[0076] Preferably, in order to save the space occupied by the packaging, the lowermost packaging box for transporting the car roof can also be cut, and cutting off the positioning surface 3 of the lowermost packaging box for transporting the car roof can save a part of the height space.

[0077] Preferably, in step two, the car roof is carried through the taking gap;

[0078] When placing the car roof, first cooperate the end close to the front windshield with the supporting surface 2.

[0079] In step two, the car roof can be carried through the taking gap. After the operator lifts the car roof, first, the end of the car roof close to the front windshield needs to be placed in the packaging box for transporting the car roof and cooperate with the supporting surface 2.

[0080] Because the other end of the roof needs to be fitted with a tailgate, the connection between the roof and the tailgate is structurally complex. Correspondingly, the support surface 2 has a corresponding hole 9. Since the hole 9 needs to mate with the roof and provide stable support, the clearance between the hole 9 and the roof is small. Therefore, when placing the roof, avoid directly fitting it into the hole 9. After lifting the roof, the operator can first place the end of the roof closest to the windshield into the packaging box used for transporting the roof, making it mate with the support surface 2. Using the guiding effect of this position, the roof can be smoothly lowered, allowing it to mate smoothly with the support surface 2. With the assistance of the support surface 2, the rear part of the roof that mates with the tailgate can easily fall into the hole 9. The operator only needs to provide appropriate pushing or pressing to completely place the roof into the packaging box.

[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.
