Description

Technical Field

[0001] The present invention relates to the field of material packaging, and specifically, to a packaging box for transporting the front hood of an automobile and a packaging method using the same. Background Art

[0002] The front hood of an automobile mainly serves to cover and protect the engine components of the automobile and is an essential part of the automobile. In some special cases, the production of automobile components and the assembly of the whole vehicle are not in the same factory. After the production of automobile components is completed, they need to be transported to the factory for assembling the whole vehicle. Therefore, as one of the important components of the whole vehicle, the front hood of the automobile also needs to be transported to the factory for assembling the whole vehicle for vehicle assembly.

[0003] Chinese Patent with Patent No. 202420915645.7 discloses a packaging body for the front hood of an automobile, including a packaging box body 1. The front hood of the automobile is placed in the packaging box body 1. There are multiple groups of the packaging box bodies 1, and multiple groups of the packaging box bodies 1 can be stacked on top of each other in the vertical direction. All the upper group of the packaging box bodies 1 are placed by rotating 180 degrees in the horizontal direction relative to the adjacent lower group of the packaging box bodies 1, so that the head of the front hood of the automobile in the upper group of the packaging box bodies 1 corresponds to the tail of the front hood of the automobile in the adjacent lower group of the packaging box bodies 1, and the tail of the front hood of the automobile in the upper group of the packaging box bodies 1 corresponds to the head of the front hood of the automobile in the adjacent lower group of the packaging box bodies 1. Positioning components are provided between multiple groups of the packaging box bodies 1. Although the positioning of the front hood of the automobile can be achieved in this way, since there is a lack of limitation on the front hood of the automobile in the height direction between the upper and lower layers, during transportation, violent bumps and the like may cause the front hood of the automobile to shift or even collide with each other. Summary of the Invention

The packaging box for transporting the front hood of the automobile is provided with a positioning surface and a supporting surface, and the front hood of the automobile therein is limited in the height direction through the cooperation of the positioning surface and the supporting surface.

[0005] To achieve the above object, the present invention provides a packaging box for transporting the front hood of an automobile, including a packaging box body, a supporting surface, a positioning surface, a positioning block and a limiting groove cooperating with the positioning block. The positioning block and the limiting groove are respectively located on the upper surface and the lower surface of the packaging box body. The supporting surface and the positioning surface are respectively located in the upper part and the lower part of the packaging box body. The supporting surface cooperates with the first surface of the front hood of the automobile, and the positioning surface cooperates with the second surface of the front hood of the automobile;

[0006] A protrusion is provided along the outer edge of the supporting surface of the packaging box body, and the protrusion and the positioning surface enclose a receiving cavity, and the front hood of the automobile is placed in the receiving cavity.

[0007] Preferably, the packaging box body is further provided with a taking groove, which is located at the edge of the accommodating cavity and communicates with the accommodating cavity.

[0008] Preferably, the packaging box body is provided with a cavity, and the cavity connects the supporting surface and the positioning surface.

[0009] Preferably, the depth of the taking groove is lower than the depth of the accommodating cavity.

[0010] Preferably, the lower part of the packaging box body is provided with a first reinforcing beam and a second reinforcing beam which are arranged in a staggered manner, and the first reinforcing beam and the second reinforcing beam intersect to form a weight-reducing groove.

[0011] Preferably, the positions where the first reinforcing beam and the second reinforcing beam are attached to the front hood of the vehicle form a positioning surface.

[0012] Preferably, the packaging box for transporting the front hood of the vehicle is integrally formed with EPS foam.

[0013] The present invention provides a packaging method using the above-mentioned packaging box for transporting the front hood of the vehicle, including:

[0014] Step 1: Take a tray and place it at the bottommost layer, place the calcium plastic board with the opening facing upward on the tray, and place the packaging box for transporting the front hood of the vehicle inside the calcium plastic board;

[0015] Step 2: Take the front hood of the vehicle and place it in the accommodating cavity, and take the packaging box for transporting the front hood of the vehicle and cover it on the front hood of the vehicle;

[0016] Step 3: Repeat Step 2 until the height of the packaging box for transporting the front hood of the vehicle at the topmost layer meets the requirements;

[0017] Step 4: Take the calcium plastic board with the opening facing downward and cover it on the packaging box for transporting the front hood of the vehicle at the topmost layer.

[0018] Preferably, in Step 2, the front hood of the vehicle is carried through the taking groove;

[0019] When placing the front hood of the vehicle, first cooperate the narrower end of the front hood of the vehicle with the supporting surface.

[0020] Preferably, in Step 2, when taking the packaging box for transporting the front hood of the vehicle and covering it on the front hood of the vehicle, the cavity is used to discharge the air between two adjacent packaging boxes for transporting the front hood of the vehicle.

[0021] According to the above technical solution, after the front hood of the vehicle of the present invention is placed in the accommodation cavity, the first surface of the vehicle cooperates with the support surface. Preferably, the support surface is set as a curved surface that is conformable to the first surface of the front hood of the vehicle, which can better realize the support of the front hood of the vehicle. The protrusions are located around the front hood of the vehicle to limit the position of the front hood of the vehicle. Through the cooperation of the protrusions and the support surface, effective limitation of the front hood of the vehicle can be achieved, so that the front hood of the vehicle cannot slide in the horizontal plane.

[0022] The packaging box for transporting the front hood of the vehicle located above is provided with a positioning surface. When the packaging box for transporting the front hood of the vehicle located above is placed in place, its positioning surface will cooperate with the second surface of the front hood of the vehicle.

[0023] By setting the cooperation of the positioning block and the limiting groove, the relative position of two adjacent packaging boxes for transporting the front hood of the vehicle is kept stable during cooperation. Thus, the positioning surface of the upper packaging box for transporting the front hood of the vehicle can reliably cooperate with the front hood of the vehicle below.

[0024] Since the front hood of the vehicle is also placed in the packaging box for transporting the front hood of the vehicle located above, by using the gravity of the front hood of the vehicle, the positioning surface can apply a certain pressure to the front hood of the vehicle below. Under the action of this pressure, the front hood of the vehicle can maintain a stable position, thereby realizing the reliable limitation of the front hood of the vehicle. The position stability of the front hood of the vehicle during transportation is ensured.

[0025] Other features and advantages of the present invention will be described in detail in the subsequent specific implementation section. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The following will describe in detail the specific implementation manners of the present invention with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only for explaining and understanding the present invention, and are not used to limit the present invention.

[0041] In the present invention, unless otherwise stated, the directional terms included in terms such as "upper surface, lower surface, upper part, lower part, inside, lower than, intersect, fit" only represent the direction of the term in the normal use state, or the common name understood by those skilled in the art, and should not be regarded as a limitation of the term.

[0042] See Figures 1-5 The described packaging box for transporting the front hood of an automobile includes a packaging box body 1, a supporting surface, a positioning surface 2, a positioning block 3 and a limiting groove 4 that cooperates with the positioning block 3. The positioning block 3 and the limiting groove 4 are respectively located on the upper surface and the lower surface of the packaging box body 1. The supporting surface and the positioning surface 2 are respectively located on the upper part and the lower part of the packaging box body 1. The supporting surface cooperates with the first surface of the front hood of the automobile, and the positioning surface 2 cooperates with the second surface of the front hood of the automobile;

[0043] A protrusion 12 is provided along the outer edge of the supporting surface of the packaging box body 1. The protrusion 12 and the positioning surface 2 enclose an accommodating cavity 7, and the front hood of the automobile is placed in the accommodating cavity 7.

[0044] Through the implementation of the above technical solution, after the front hood of the vehicle is placed in the accommodation cavity 7, the first surface of the front hood of the vehicle cooperates with the support surface. Preferably, the support surface is set as a curved surface that is conformally shaped with the first surface of the front hood of the vehicle, which can better realize the support of the front hood of the vehicle. The protrusion 12 is located around the front hood of the vehicle to play a limiting role on the front hood of the vehicle. Through the cooperation of the protrusion 12 and the support surface, effective limitation of the front hood of the vehicle can be achieved, so that the front hood of the vehicle cannot slide in the horizontal plane.

[0045] The packaging box for transporting the front hood of the vehicle located above is provided with a positioning surface 2. When the packaging box for transporting the front hood of the vehicle located above is placed in place, its positioning surface 2 will cooperate with the second surface of the front hood of the vehicle. Preferably, the positioning surface 2 is set as a curved surface that is conformally shaped with the second surface of the front hood of the vehicle, which can realize the effective cooperation between the packaging box for transporting the front hood of the vehicle located above and the front hood of the vehicle below, and realize the limitation of the front hood of the vehicle in the height direction.

[0046] By setting the positioning block 3 to cooperate with the limiting groove 4, the relative positions of two adjacent packaging boxes for transporting the front hood of the vehicle are kept stable during cooperation. Thus, the positioning surface 2 of the packaging box for transporting the front hood of the vehicle above can reliably cooperate with the front hood of the vehicle below.

[0047] Since the front hood of the vehicle is also placed in the packaging box for transporting the front hood of the vehicle located above, by using the gravity of the front hood of the vehicle, the positioning surface 2 can exert a certain pressure on the front hood of the vehicle below. Under the action of this pressure, the front hood of the vehicle can maintain a stable position, thereby realizing the reliable limitation of the front hood of the vehicle and ensuring the position stability of the front hood of the vehicle during the conveying process.

[0048] In this embodiment, preferably, the packaging box body 1 is further provided with a taking groove 5, and the taking groove 5 is located at the edge of the accommodation cavity 7 and is communicated with the accommodation cavity 7.

[0049] By setting the taking groove 5 to be communicated with the accommodation cavity 7, the hand of the operator can be put into the lower part of the front hood of the vehicle through the taking groove 5, so that a force can be conveniently applied to the front hood of the vehicle, facilitating the operator to take or place the front hood of the vehicle.

[0050] In this embodiment, preferably, the depth of the taking groove 5 is lower than the depth of the accommodation cavity 7.

[0051] When the depth of the taking groove 5 is lower than the depth of the accommodation cavity 7, the hand of the operator can directly reach into the accommodation cavity 7 along the bottom of the taking groove 5 to the lower part of the front hood of the vehicle. Therefore, it is very easy to operate the front hood through the taking groove 5.

[0052] Since the front hood of a car is generally large in size and has a certain weight, when taking the front hood, generally two people are required to lift it together. Preferably, taking grooves 5 are respectively arranged along both sides of the front hood of the car, enabling two people to lift the front hood of the car together. At the same time, two taking grooves 5 are arranged on each side, allowing each person to operate with both hands.

[0053] Preferably, the position of the taking groove 5 on the packaging box for transporting the front hood of the car is fixed. Moreover, through the cooperation of the front hood of the car and the supporting surface, the relative position of the taking groove 5 and the front hood of the car is also fixed. Therefore, when a robotic arm needs to grasp or place the front hood of the car, only by positioning the packaging box for transporting the front hood of the car can the reliable grasping and placing of the front hood of the car by the robotic arm be achieved.

[0054] In this embodiment, preferably, the lower part of the packaging box body 1 is provided with a first reinforcing beam 61 and a second reinforcing beam 62 arranged in an alternating manner, and the first reinforcing beam 61 and the second reinforcing beam 62 intersect to form a weight reduction groove 63.

[0055] By providing the first reinforcing beam 61 and the second reinforcing beam 62 to ensure the structural strength of the packaging box body 1, and the first reinforcing beam 61 and the second reinforcing beam 62 intersect to form a weight reduction groove 63. Therefore, the side of the packaging box body 1 facing away from the front hood of the car includes many inwardly concave weight reduction grooves 63. By providing these grooves, the material consumption of the packaging box body 1 can be significantly reduced, and the material cost of the packaging box body 1 can be lowered.

[0056] Preferably, the first reinforcing beam 61 and the second reinforcing beam 62 are respectively parallel to the long side and the short side of the packaging box body 1 itself. Then, the four sides of the packaging box body 1 can also be provided with the structure of the first reinforcing beam 61 and the second reinforcing beam 62. In this way, the first reinforcing beam 61 and the second reinforcing beam 62 can be arranged most effectively, further reducing the distribution quantity of the first reinforcing beam 61 and the second reinforcing beam 62, and achieving the purpose of saving materials.

[0057] Preferably, at least two positioning blocks 3 are provided, and two of the multiple positioning blocks 3 are respectively arranged at two diagonals of the packaging box body 1. Through the fixation of the diagonal line, the relative position of two adjacent packaging box bodies 1 can be effectively controlled. Therefore, by arranging two positioning blocks 3 at two diagonals of the packaging box body 1, the position limitation of two adjacent packaging box bodies 1 along the diagonal line can be achieved.

[0058] Considering from the perspective of saving space occupation, the packaging box body 1 needs to be set to a relatively regular shape, usually set to a rectangle, which will be very beneficial to the close arrangement of the packaging boxes for transporting the front hoods of the cars in a limited space, thereby effectively saving space occupation.

[0059] Preferably, four positioning blocks 3 are provided, and the four positioning blocks 3 are preferably arranged at positions close to the four corners of the packaging box body 1.

[0060] Since the positioning block 3 needs to relatively position the upper and lower packaging box bodies 1, the positioning block 34 needs to have a certain strength. The cross-sectional area and height of the positioning block 3 need to be designed accordingly in combination with the strength requirements and positioning reliability.

[0061] Preferably, due to the limitation of the available space on the surface of the packaging box body 1, the cross-sectional shapes of the positioning blocks 3 can be different, but the heights of the positioning blocks 3 need to be set the same.

[0062] Through the cooperation of the multiple positioning blocks 3 and the limiting grooves 4, there is no longer a degree of freedom of relative movement between two adjacent packaging box bodies 1. That is, through the cooperation of the multiple positioning blocks 3 and the limiting grooves 4, two adjacent packaging box bodies 1 are limited in both the X and Y directions, improving the stability after stacking of the packaging box body 1. During transportation, the relative positions between two adjacent packaging box bodies 1 will not change.

[0063] Preferably, six positioning blocks 3 are provided. Four positioning blocks 3 are respectively located at the four corners of the packaging box body 1, and the other two positioning blocks 3 are respectively located on two opposite long sides and are arranged at positions as far away from each other as possible according to the actual space.

[0064] In this embodiment, preferably, the side walls of the limiting groove 4 are provided with a first reinforcing beam 61 and a second reinforcing beam 62 that intersect.

[0065] The position where the first reinforcing beam 61 and the second reinforcing beam 62 intersect is set to be consistent with the position of the limiting groove 4. Through the cooperation of the first reinforcing beam 61 and the second reinforcing beam 62 with the limiting block, reliable limiting of two adjacent packaging box bodies 1 can be achieved. Setting the limiting groove 4 to a structure shared with the weight reduction groove 63 can reduce the number of structural components of the packaging box for transporting the automobile front hood, and at the same time reduce the complexity of the mold design of the packaging box for transporting the automobile front hood.

[0066] In this embodiment, preferably, a positioning surface 2 is formed at the position where the first reinforcing beam 61 and the second reinforcing beam 62 are in contact with the automobile front hood.

[0067] A curved surface that is shaped to conform to the second surface is provided on the side of the first reinforcing beam 61 and the second reinforcing beam 62 that is in contact with the second surface of the automobile front hood. This curved surface is set as the positioning surface 2. When the upper packaging box body 1 is covered on the lower packaging box body 1, the positioning surface 2 can well conform to the second surface of the automobile front hood, and while achieving reliable stacking, it can also limit the lower automobile front hood to ensure stability during transportation.

[0068] An automobile front hood is placed inside the packaging box body 1. By using the weight of the automobile front hood, the packaging box body 1 applies a certain pressure to the lower automobile front hood through the positioning surface 2, and under the action of this pressure, it can ensure that the automobile front hood does not move up and down.

[0069] After the automobile front hood is placed on the supporting surface, its height will be higher than the upper surface of the packaging box body 1. At this time, a groove is provided at the bottom of the upper packaging box body 1 to accommodate the part of the automobile front hood that is higher than the packaging box body 1. The positions where the first reinforcing beam 61 and the second reinforcing beam 62 are in contact with the automobile front hood form the positioning surface 2, and the positioning surface 2 is formed with a curved surface that is in imitation of the second surface of the automobile front hood, which can cooperate with the surface of the automobile front hood that is higher than the packaging box body 1, so as to realize the accommodation of the part of the automobile front hood that is higher than the packaging box body 1. In this way, the cooperation of two adjacent packaging boxes for transporting automobile front hoods can well realize the storage and protection of the automobile front hood. Moreover, by setting the positioning surface 2 at the lower part of the packaging box body 1, the thickness of the packaging box for transporting the automobile front hood can be effectively reduced, so that the packaging box for transporting the automobile front hood has a smaller height, thereby improving the space utilization efficiency.

[0070] The packaging box for transporting the automobile front hood is integrally formed with EPS foam.

[0071] Due to the extremely low density of EPS foam, using EPS foam can reliably reduce the weight of the packaging box for transporting the automobile front hood and reduce the transportation cost.

[0072] In this embodiment, preferably, the packaging box body 1 is provided with a cavity 11, and the cavity 11 connects the supporting surface and the positioning surface 2.

[0073] In one embodiment, the cavity 11 is arranged at a position corresponding to the regular curved surface of the automobile front hood, and the solid part between the positioning surface 2 and the supporting surface is used to support and isolate two adjacent automobile front hoods. In this way, while reliably supporting and protecting the automobile front hood, the material usage can be reduced and the material cost can be lowered.

[0074] In one embodiment, the cavity 11 is located in the middle of the packaging box body 1. The solid part around the cavity 11 can achieve a reliable supporting effect on the automobile front hood, and by setting the thickness of the solid part, two adjacent automobile front hoods can be effectively isolated to avoid bumps during transportation.

[0075] Preferably, after the automobile hood is placed, it is first necessary to place the next automobile hood transport packaging box on top of the automobile hood. When the positioning surface 2 cooperates with the second surface, the space between the positioning surface 2 and the second surface gradually decreases. Therefore, the air in the space needs to be continuously discharged during the placement of the automobile hood transport packaging box. If the air is only discharged through the gap between the second surface and the positioning surface 2, air resistance will be encountered when placing the automobile hood transport packaging box. Therefore, the provision of the cavity 11 can facilitate the discharge of air in the space from the cavity 11, thereby improving the work efficiency when placing the automobile hood transport packaging box, and can also improve the accuracy of the position of the automobile hood transport packaging box after placement.

[0076] The present invention also provides a packaging method using a packaging box for transporting a front hatch of an automobile, comprising:

[0077] Step 1: Take the tray 81 and place it at the bottom, place the calcium plastic plate 82 with its opening facing upward on the tray 81, and place the packaging box for transporting the front hatch of the automobile inside the calcium plastic plate 82;

[0078] Step 2: Place the front hatch of the car on the support surface, and place the cover of the packaging box for transporting the front hatch of the car on the front hatch of the car;

[0079] Step 3: Repeat step 2 until the height of the topmost car front hatch transport packaging box reaches the requirement;

[0080] Step 4: Take the calcium plastic plate 82 and open it downward to cover the uppermost automobile front hatch cover transportation packaging box.

[0081] Through the implementation of the above technical solution, the lower part of the pallet 81 is set in a "川" shape, which is convenient for forklift operation and is conducive to the transportation of the front hood of the car; a calcium plastic plate 82 is placed under the packaging box for transporting the front hood of the car as an oil receiving tray, which can receive the oil dripping from the sheet metal above, and the upper calcium plastic plate 82 can play a dust-proof role.

[0082] The car hood is placed in a packaging box for transporting the car hood. According to the size of the packaging box, at least one car hood is placed in each packaging box. Then another packaging box for transporting the car hood is stacked on top and another car hood is placed. In this way, the car hood is packaged and stored.

[0083] Two adjacent automobile hood transport packaging boxes are stacked in the height direction by the cooperation of the positioning block 3 and the limiting groove 4. Preferably, the edges of the two adjacent packaging box bodies 1 are in contact with each other, so that the automobile hood located therebetween can be reliably protected.

[0084] Preferably, a handle 9 is provided on the packaging box body 1, and an operator can easily take the packaging box body 1 through the handle 9. In actual production, the operator needs to first take the packaging box for transporting the front engine hood of the vehicle, and determine its position by the cooperation of the positioning block 3 and the limiting groove 4 with the packaging box for transporting the front engine hood of the vehicle below, and then place the front engine hood of the vehicle.

[0085] Preferably, the positioning surface 2 and the package support surface are communicated through a cavity 11. The cavity 11 is arranged at a position corresponding to the regular curved surface of the front engine hood of the vehicle, and the solid part between the positioning surface 2 and the support surface is used to support and isolate two adjacent front engine hoods of the vehicle. In this way, while reliably supporting and protecting the front engine hood of the vehicle, the material usage can be reduced and the material cost can be lowered.

[0086] Preferably, in step two, the top of the packaging box for transporting the front engine hood of the vehicle at the topmost layer is set to be horizontal.

[0087] Setting the top of the packaging box for transporting the front engine hood of the vehicle at the topmost layer to be horizontal is very beneficial for logistics packaging. Preferably, the packaging box for transporting the front engine hood of the vehicle at the topmost layer can be cut along the upper surface of the packaging box body 1. It is also very easy to cut the packaging box body 11 made of EPS foam.

[0088] Preferably, in order to save the space occupied by the packaging, the packaging box for transporting the front engine hood of the vehicle at the lowermost layer can also be cut, and cutting off the positioning surface 2 of the packaging box for transporting the front engine hood of the vehicle at the lowermost layer can save a part of the height space.

[0089] In this embodiment, preferably, in step two, the front engine hood of the vehicle is carried through the taking groove 5, and when placing the front engine hood of the vehicle, the narrower end of the front engine hood of the vehicle is first fitted with the support surface.

[0090] When the operator lifts the front engine hood of the vehicle, the smaller end of the front engine hood of the vehicle can be first placed into the packaging box for transporting the front engine hood of the vehicle to make it cooperate with the support surface. By using the cooperation at this position and the guiding function of the protrusion 12, the front engine hood of the vehicle can be smoothly placed down to achieve the cooperation between the front engine hood of the vehicle and the support surface.

[0091] Adopting this method of placing the front engine hood of the vehicle obliquely in the accommodating cavity 7 can also effectively discharge the air between the front engine hood of the vehicle and the lower support surface, making the placement process of the front engine hood of the vehicle more stable.

[0092] In this embodiment, preferably, in step three, when the packaging box for transporting the front engine hood of the vehicle is covered on the front engine hood of the vehicle, the cavity 11 is used to discharge the air between two adjacent packaging boxes for transporting the front engine hood of the vehicle.

[0093] After the vehicle front hood is placed, it is necessary to place the next packaging box for transporting the vehicle front hood above the vehicle front hood. When the positioning surface 2 cooperates with the second surface of the vehicle front hood, the space between the positioning surface 2 and the second surface gradually decreases. Therefore, during the process of placing the packaging box for transporting the vehicle front hood, the air in the space needs to be continuously discharged. If this air is only discharged through the gap between the second surface and the positioning surface 2, air resistance will be encountered when placing the packaging box for transporting the vehicle front hood. Since the self-weight of the packaging box for transporting the vehicle front hood is very small, the air resistance has a greater impact on the movement trajectory of the packaging box for transporting the vehicle front hood, which may cause position deviation after the packaging box for transporting the vehicle front hood is placed. The cavity 11 is provided to facilitate the discharge of the air in the space from the cavity 11, which can improve the accuracy of the position after the packaging box for transporting the vehicle front hood is placed, thereby enhancing the working efficiency when placing the packaging box for transporting the vehicle front hood.
