A rear door bearing surface A is provided on the upper part of the packaging positioning cavity of the packaging box body, and a rear door bearing surface B is provided on the lower part of the packaging positioning cavity. The rear doors are carried by stacking multiple such rear door packaging boxes. However, since the rear door usually has a certain curvature and a certain height when placed horizontally, when the rear doors are stored in this way by stacking in the height direction, the number of rear doors that can be stored per unit height is limited. Moreover, the rear door is relatively heavy. When the rear doors are stored by stacking in the height direction, when the stacking height reaches a certain level, it is difficult to take or place the topmost rear door. Summary of the Invention

[0004] The object of the present invention is to provide a logistics appliance for transporting a rear door and a packaging method. The logistics appliance for transporting a rear door can accommodate the rear door along the length direction without increasing the height of the rear door, and it is very convenient to take or place the rear door.

[0005] To achieve the above object, the present invention provides a logistics appliance for transporting a rear door, which includes a first fixing member, a second fixing member, and side limiting members located between the first fixing member and the second fixing member. The first fixing member is provided with a plurality of first material grooves, the second fixing member is provided with a plurality of second material grooves, the first material grooves and the second material grooves cooperate with the upper end and the lower end of the rear door respectively to fix the rear door. The first material grooves and the second material grooves correspond to each other one by one. The side limiting members are provided with limiting grooves, and the limiting grooves cooperate with the side surfaces of the rear doors to isolate two adjacent rear doors.

[0006] The side limiting members include a left limiting member and a right limiting member, and the left limiting member and the right limiting member are symmetrically arranged.

[0007] Preferably, the first fixing member further includes a plurality of second material grooves, and the first material grooves and the second material grooves are alternately arranged.

[0008] Preferably, the first fixing member is disposed above the rear door, and the number of the first material grooves on the first fixing member is one less than that of the second material grooves.

[0009] Preferably, the first fixing member and the second fixing member are set to have the same height.

[0010] Preferably, the limiting groove includes a first limiting groove and a second limiting groove, and the first limiting groove and the second limiting groove are alternately arranged.

[0011] Preferably, the first fixing member and the second fixing member are respectively provided with positioning structures, and the side limiting member is connected to the first fixing member and the second fixing member through the positioning structures.

[0012] The present invention further provides a packaging method, which uses the logistics appliance for transporting the rear door, and includes:

[0013] Step 1: Place a tray, a calcium plastic board and the second fixing member in sequence from bottom to top;

[0014] Step 2: Place the rear door in sequence;

[0015] Step 3: Place the side limiting member and the first fixing member correspondingly;

[0016] Step 4: Finally, cover the calcium plastic board above the first fixing member.

[0017] Preferably, in Step 3, the left limiting member and the right limiting member are respectively provided with distinguishing marks, and the left limiting member and the right limiting member are distinguished by the distinguishing marks.

[0018] Preferably, the distinguishing marks are disposed on the upper end surface and the lower end surface of the side limiting member.

[0019] According to the above technical solution, the second fixing member of the present invention is placed below, the lower end of the rear door is placed in the second fixing member in cooperation with the second material groove, and a plurality of second material grooves are distributed along the length direction of the second fixing member, so that a plurality of rear doors are arranged in sequence along the length direction of the second fixing member. Preferably, the second material groove is provided with a curved surface that is in conformity with the surface of the lower end of the rear door, so that the inner wall of the second material groove can be completely fitted with the surface of the lower end of the rear door, and the second material groove can not only accommodate the rear door, but also isolate two adjacent rear doors.

[0020] The side limiting member is located on the side of the rear door. Preferably, the inner wall of the limiting groove is provided with a curved surface that is in conformity with the surface of the side of the rear door, so that the side limiting member can not only accommodate the side of the rear door, but also isolate two adjacent rear doors.

[0021] Preferably, two side limiters are provided: a left side limiter and a right side limiter. The left side limiter and the right side limiter are respectively located on the left side and the right side of the rear door. Since the rear door is usually symmetric left and right, the left side limiter and the right side limiter are symmetrically arranged.

[0022] The first fixing member is located above the rear door.

By determining the distance between two adjacent first material grooves, the gap between two adjacent rear doors can be fixed, and then the relative positions of two adjacent rear doors can be determined, thereby determining the distances between two adjacent second material grooves and two adjacent limiting grooves.

[0024] Preferably, by setting the heights of the first fixing member and the second fixing member and the thicknesses of the two side limiters, the protruding positions of the rear door can be wrapped by the logistics appliance for transporting the rear door. After wrapping, two adjacent rear doors will not come into contact or collide with each other.

[0025] Therefore, the logistics appliance for transporting the rear door can accommodate the rear door along the length direction, ensuring the stable position of the rear door during transportation and preventing the rear doors located in the logistics appliance for transporting the rear door from colliding with each other. At the same time, the way of placing the rear door of the car along the length direction does not increase its height during the packaging process, avoiding the problem that the operator needs to lift or raise the rear door during the packaging or unloading of the rear door, which is convenient for the operator to pack the rear door.

[0026] Other features and advantages of the present invention will be described in detail in the subsequent specific implementation part. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] The following will describe in detail the specific embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not intended to limit the present invention.

[0051] In the present invention, unless otherwise stated, the directional terms included in terms such as "upper end, lower end, alternate, above" only represent the orientation of the term in its normal use state, or the common name understood by those skilled in the art, and should not be regarded as a limitation to the term.

[0052] The present invention provides a logistics appliance for transporting a rear door, including a first fixing member 1, a second fixing member 2, and a side limiting member 3 located between the first fixing member 1 and the second fixing member 2. The first fixing member 1 is provided with a plurality of first material grooves 12, and the second fixing member 2 is provided with a plurality of second material grooves 11. The first material grooves 12 and the second material grooves 11 cooperate with the upper end and the lower end of the rear door respectively to fix the rear door. The first material grooves 12 and the second material grooves 11 correspond to each other one by one. The side limiting member 3 is provided with a limiting groove, and the limiting groove cooperates with the side surface of the rear door to isolate two adjacent rear doors.

[0053] The side limiting member 3 includes a left side limiting member and a right side limiting member, and the left side limiting member and the right side limiting member are symmetrically arranged.

[0054] By implementing the above technical solution, the second fixing member 2 is placed below, and the lower end of the rear door is placed in the second fixing member 2 in cooperation with the second material groove 11. The plurality of second material grooves 11 are distributed along the length direction of the second fixing member 2, so that a plurality of rear doors are arranged in sequence along the length direction of the second fixing member 2. Preferably, the second material groove 11 is provided with a curved surface that is in conformity with the surface of the lower end of the rear door, so that the inner wall of the second material groove 11 can be completely fitted with the surface of the lower end of the rear door, so that the second material groove 11 can not only accommodate the rear door, but also isolate two adjacent rear doors.

[0055] The side limiting member 3 is located on the side surface of the rear door. Preferably, the inner wall of the limiting groove is provided with a curved surface that is in conformity with the surface of the side surface of the rear door, so that the side limiting member 3 can not only accommodate the side surface of the rear door, but also isolate two adjacent rear doors.

[0056] Preferably, two side limiting members 3 are provided: a left side limiting member and a right side limiting member. The left side limiting member and the right side limiting member are respectively located on the left side and the right side of the rear door. Since the rear door is usually symmetric about the left and right, the left side limiting member and the right side limiting member are symmetrically arranged.

[0057] The first fixing member 1 is located above the rear door. The inner wall of the first material groove 12 is provided with a curved surface that is in conformity with the surface of the upper end of the rear door, which can cooperate with the upper end of the rear door to realize the position limitation of the rear door located therein, and can also isolate two adjacent rear doors.

[0058] Preferably, the upper and lower end faces of the side limit member 3 are respectively in contact with the first fixing member 1 and the second fixing member 2. Through the cooperation of the first fixing member 1, the second fixing member 2 and the two side limit members 3, the entire periphery of the rear door can be surrounded. Preferably, by setting the distance between two adjacent first material grooves 12, the effective isolation of two adjacent rear doors can be achieved. By determining the distance between two adjacent first material grooves 12, the gap between two adjacent rear doors can be fixed, and then the relative positions of two adjacent rear doors can be determined, thereby determining the distances between two adjacent second material grooves 11 and between two adjacent limit grooves.

[0059] Preferably, by setting the heights of the first fixing member 1 and the second fixing member 2 and the thicknesses of the two side limit members 3, the protruding positions of the rear door can be wrapped by the logistics appliance for transporting the rear door. After wrapping, two adjacent rear doors will not come into contact or collide with each other.

[0060] Therefore, the logistics appliance for transporting the rear door can accommodate the rear door along the length direction, ensuring the stable position of the rear door during transportation and preventing the rear doors located within the logistics appliance for transporting the rear door from colliding with each other. At the same time, placing the automotive rear door along the length direction ensures that the height of the rear door does not increase during the packaging process, avoiding the problem that operators need to lift or raise the rear door during the packaging or unloading process of the rear door, which facilitates the packaging of the rear door by the operators.

[0061] In this embodiment, preferably, the first fixing member 1 further includes a plurality of second material grooves 11, and the first material grooves 12 and the second material grooves 11 are arranged alternately.

[0062] Since the upper end of the rear door is usually smaller in size and lighter in mass than the lower end of the rear door, when packaging the rear door, if all the rear doors are placed in the same direction, the second fixing member 2 for placing the lower end of the rear door will be thinner. The thinner size will affect the structural strength of the second fixing member 2. If the second fixing member 2 is located below the rear door during transportation, there is a risk of packaging failure.

[0063] By arranging the first material grooves 12 and the second material grooves 11 alternately in the first fixing member 1, during the packaging process of the rear door, the rear doors placed in the same direction as the installation direction and the rear doors placed in the opposite direction to the installation direction are alternately distributed in the length direction of the first fixing member 1. This makes the mass distribution of the logistics appliance for transporting the rear door more uniform along the height direction, and can effectively solve the problem that the thickness of the first fixing member 1 or the second fixing member 2 located below is small and the structural strength is insufficient.

[0064] When the first fixing member 1 is provided with the first material grooves 12 and the second material grooves 11 alternately distributed, the second fixing member 2 correspondingly needs to be provided with the second material grooves 11 and the first material grooves 12 alternately distributed to achieve reliable support for the upper and lower ends of the rear door.

[0065] In this embodiment, preferably, the first fixing member 1 is disposed above the rear door, and the number of the first material grooves 12 on the first fixing member 1 is one less than the number of the second material grooves 11.

[0066] The number of the first material grooves 12 on the first fixing member 1 is one less than the number of the second material grooves 11, that is, both ends of the first fixing member 1 are provided with the second material grooves 11 to cooperate with the lower end of the rear door. Correspondingly, the upper ends of the rear door are placed at both ends of the second fixing member 2 below. Since the size of the upper end of the rear door is small, the supporting parts at both ends of the second fixing member 2 are wider and have better structural strength. During transportation, the second fixing member 2 at the lower part of the logistics appliance for transporting the rear door needs to bear the gravity of the rear door placed therein. By increasing the thickness of both ends of the second fixing member 2, the structural strength of the second fixing member 2 can be effectively increased, and the reliability of the logistics appliance for transporting the rear door during use can be improved.

[0067] In this implementation process, preferably, the heights of the first fixing member 1 and the second fixing member 2 are set to be the same.

[0068] The area of the upper end of the rear door that needs to be protected is small, but there is a large processing surface at the lower end of the rear door that needs to be protected, and this processing surface has a certain height. Therefore, the second material groove 11 needs to have a certain height. When the rear door is placed alternately in the forward and reverse directions, in order to achieve reliable protection of the lower end of the rear door, both the first fixing member 1 and the second fixing member 2 need to be set to a sufficient height to meet the protection of the processing surface at the lower end of the rear door.

[0069] After the rear door is placed on the first fixing member 1 and the second fixing member 2, the solid part between the alternately arranged first material grooves 12 and the second material grooves 11 can isolate and protect the processing surfaces of two adjacent rear doors.

[0070] Preferably, the depth of the second material groove 11 is set to be greater than the depth of the first material groove 12, so that the second material groove 11 cooperating with the processing surface at the lower end of the rear door can achieve protection of the lower end of the rear door, and the side of the first material groove 12 cooperating with the upper end of the rear door close to another rear door is set to be lower, and this lower side can meet the protection of the upper end of the rear door and also can achieve the purpose of saving materials.

[0071] In this embodiment, preferably, the limiting grooves include a first limiting groove 31 and a second limiting groove 32, and the first limiting groove 31 and the second limiting groove 32 are alternately arranged.

[0072] Since the back door is alternately distributed in the forward and reverse directions along the length direction of the first fixing member 1 , two matching curved surfaces need to be provided corresponding to the limiting grooves, that is, the first limiting grooves 31 and the second limiting grooves 32 are alternately arranged on the side limiting member 3 .

[0073] In this embodiment, preferably, the first fixing member 1 and the second fixing member 2 are respectively provided with positioning structures, and the side limiting member 3 is connected to the first fixing member 1 and the second fixing member 2 via the positioning structure.

[0074] In order to facilitate the connection and position limitation between the first fixing member 1, the second fixing member 2 and the side limit member 3, the first fixing member 1 and the second fixing member 2 are respectively provided with a positioning structure, through which the side limit member 3 can achieve relative position limitation with the first fixing member 1 and the second fixing member 2 respectively.

[0075] The present invention also provides a packaging method, which uses the rear door transportation logistics device, comprising:

[0076] Step 1, placing the tray 5, the calcium plastic plate 6 and the second fixing member 2 in order from bottom to top;

[0077] Step 2: Insert the back door one by one;

[0078] Step 3, insert the side limiter 3 and the first fixing member 1 accordingly;

[0079] Step 4: Finally, cover the calcium plastic plate 6 on top of the first fixing member 1.

[0080] Through the implementation of the above technical solution, in order to facilitate the transportation during the process, a pallet 5 is placed first, and then the tailgate is packaged on the pallet 5 using a logistics tool for tailgate transportation. The calcium plastic plates 6 located above and below are respectively used for dust prevention and to receive oil stains dripping from the tailgate. At the same time, the calcium plastic plates 6 located above and below can also provide a force position for bundling during the packaging of the logistics tool for tailgate transportation.

[0081] In step 3, after all the back doors are placed, the left and right limiters can be pushed inward from the left and right sides respectively. After being pushed into place, the side limiters 3 on both sides can cooperate with the back doors and achieve reliable protection for the back doors.

[0082] Preferably, the positioning structure is configured as a structure in which a positioning groove matches a positioning block.

[0083] A third positioning groove 23 is provided on the second fixing member 2 located below. The positioning groove is provided with an opening, and the opening faces the edge of the second fixing member 2. A third positioning block 43 that cooperates with the third positioning groove 23 is provided on the side limiting member 3. During the installation of the side limiting member 3, the third positioning block 43 gradually slides inward through the opening of the third positioning groove 23, and the cooperation between the third positioning block 43 and the third positioning groove 23 can realize the guiding effect on the side limiting member 3 during the installation process.

[0084] Preferably, two mutually parallel third positioning blocks 43 are provided on the side limiting member 3, and the two mutually parallel third positioning blocks 43 can realize a reliable guiding effect on the side limiting member 3 during the installation of the side limiting member 3.

[0085] After the side limiting member 3 is installed, the upper first fixing member 1 can be installed. Press the first fixing member 1 downward until it is pressed in place, and the packaging of the rear door by the logistics appliance for transporting the rear door is realized. Then, cover the calcium plastic board 6 to complete the packaging of the rear door.

[0086] In this embodiment, preferably, in step 3, distinguishing marks are respectively provided on the left side limiting member and the right side limiting member, and the left side limiting member and the right side limiting member are distinguished by the distinguishing marks.

[0087] Usually, the rear door is set to have a left-right symmetric structure. Therefore, the left side limiting member and the right side limiting member also need to be symmetrically arranged. Distinguishing the left side limiting member and the right side limiting member by setting distinguishing marks can improve the working efficiency of the operator.

[0088] Since the discrimination of left and right is related to the orientation of the operator, usually, the left and right are not directly marked to distinguish the left side limiting member and the right side limiting member.

[0089] Distinguishing marks that cooperate with the side limiting member 3 are respectively provided on the first fixing member 1 and the second fixing member 2, and the left side limiting member and the right side limiting member are distinguished by the cooperation with the first fixing member 1 and the second fixing member 2.

[0090] In one embodiment, grooves or protrusions that respectively cooperate with the first fixing member 1 and the second fixing member 2 are provided on the side surface of the side limiting member 3, and the grooves or protrusions are the distinguishing marks.

[0091] The distinguishing marks of the left side limiting member and the right side limiting member are symmetrically arranged, and the distinguishing marks are arranged at positions far from the midline of the side limiting member 3. Preferably, grooves that can be aligned with each other are provided on the side surfaces of the side limiting member 3 and the first fixing member 1, and protrusions that can be aligned with each other are provided on the side surfaces of the side limiting member 3 and the second fixing member 2. Then, the operator can judge whether the side limiting member 3 should be placed on the left side or the right side by observing the positions of the grooves and the protrusions. However, this method does not have an anti-mistake function.

[0092] In this embodiment, preferably, the distinguishing marks are provided on the upper and lower end faces of the side limiting member 3.

[0093] Distinguishing blocks are respectively provided on the upper and lower end faces of the side limiting member 3. The distinguishing blocks are provided on the same side of the side limiting member 3. Corresponding to the distinguishing blocks, distinguishing grooves are respectively provided on the first fixing member 1 and the second fixing member 2. During use, the operator can judge whether the side limiting member 3 is on the left or right by observing the positions of the distinguishing blocks.

[0094] Adopting this method has a certain anti-mistake function. When the side limiting member 3 is placed in the wrong position, it cannot cooperate with the first fixing member 1 and the second fixing member 2, so that the side limiting member 3 cannot be attached to the first fixing member 1 and the second fixing member 2, and the error of this packaging is easy to be found.

[0095] Preferably, the distinguishing marks are set as positioning blocks that cooperate with the fixing structure.

[0096] The distinguishing marks can also be set as positioning blocks.

[0097] The second fixing member 2 is provided with third positioning grooves 23 that open towards its edge. Two third positioning grooves 23 are provided on each side, and the two third positioning grooves 23 are symmetrically arranged along the midline in the length direction of the second fixing member 2.

[0098] The first fixing member 1 is provided with two asymmetrically arranged first positioning grooves 21 and second positioning grooves 22. The side limiting member is provided with a first positioning block 41 and a second positioning hole 42 that respectively cooperate with the first positioning groove 21 and the second positioning groove 22. In this way, after the side limiting member 3 is placed in the wrong position, the first positioning block 41 and the second positioning hole 42 on its upper surface cannot cooperate with the first positioning groove 21 and the second positioning groove 22 on the first fixing member 1, thus reminding the operator that the position of the side limiting member 3 is incorrect and needs to be adjusted.

[0099] Preferably, the second positioning groove 22 is provided at the edge of the first fixing member 1. This can facilitate the operator to identify the second positioning block 42 on the side limiting member 3 that cooperates with the second positioning groove 22 located at the edge, and can select a suitable side limiting member 3 in advance, thus effectively improving work efficiency.

[0100] Preferably, handles 7 are provided on the first fixing member 1, the second fixing member 2 and the side limiting member 3, and the operator can easily take and place them through the handles 7.

[0101] In this embodiment, preferably, the lower part of the packaging box body 1 is provided with first reinforcing beams 81 and second reinforcing beams 82 that are arranged in a staggered manner. The first reinforcing beams 81 and the second reinforcing beams 82 intersect to form a weight reduction groove.

[0102] By providing the first reinforcing beam 81 and the second reinforcing beam 82 to ensure the structural strength of the packaging box body 1, the first reinforcing beam 81 and the second reinforcing beam 82 intersect to form a weight-reducing groove. Therefore, one side of the packaging box body 1 facing away from the automotive front hood includes many inwardly recessed weight-reducing grooves. By providing these grooves, the material usage can be significantly reduced, and the material cost can be lowered.

[0103] The preferred embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solutions of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0104] In addition, it should be noted that, among the various specific technical features described in the above specific embodiments, they can be combined in any suitable manner without conflict. To avoid unnecessary repetition, the present invention will not separately describe various possible combination methods.

[0105] Furthermore, any combination can be made between various different embodiments of the present invention, as long as it does not violate the idea of the present invention, and it should also be regarded as the content disclosed by the present invention.
