[0043] Through the above-mentioned drawings, specific embodiments of the present invention have been shown, and more detailed descriptions will be given later. These drawings and textual descriptions are not intended to limit the scope of the concept of the present invention in any way, but to illustrate the concept of the present invention to those skilled in the art by referring to specific embodiments. Detailed implementation manners

[0044] To make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the drawings.

[0045] With the development of technology and the continuous improvement of people's living standards, electronic products play an increasingly important role in our lives. As the carrier of electronic products, the packaging box plays an important role in protecting the product, transmitting information and enhancing the product image. That is to say, the packaging box has the function of protecting electronic products and can effectively prevent electronic products from being damaged during transportation, storage and sales. Moreover, relevant information about the electronic product can be set on the surface of the packaging box to transmit the information and brand image of the electronic product and improve the competitiveness of the product.

[0046] However, during the process of product circulation, the products in the packaging box shake during the transaction, resulting in a relatively easy problem of product breakage.

[0047] Please refer to Figure 1 、 Figure 2 and Figure 3 , Figure 1 which are schematic structural diagrams of a packaging box provided by an embodiment of the present utility model, Figure 2 is Figure 1 an exploded structural diagram of the packaging box shown in Figure 3 is Figure 1 a schematic structural diagram of another state of the packaging box shown in Figure 3 is Figure 1 a schematic structural diagram of another perspective of the packaging box shown in Figure 1 The packaging box shown in Figure 3 is in a closed state, and the packaging box shown in

[0048] is in an open state. According to one aspect of the present utility model, a packaging box is provided. The packaging box may include a first housing 11, a fastening film 12, a buffer structure 13, and a second housing 14.

[0049] The first housing 11 may be rotatably connected to the second housing 14. The packaging box has an open state and a closed state. The first housing 11 can move between a first position and a second position. When the first housing 11 is at the first position, the packaging box is in the closed state. When the first housing 11 is at the second position, the packaging box is in the open state. That is, the first housing 11 can rotate relative to the second housing 14 so that the first housing 11 can switch between the first position and the second position, thereby enabling the packaging box to switch between the open state and the closed state.

[0050] The second housing 14 may have a receiving portion with an opening facing the first housing 11. At least a part of the buffer structure 13 is located in the receiving portion. The buffer structure 13 may be fixedly connected to the second housing 14. The buffer structure 13 may include an elastic structure. The buffer structure 13 may fill the receiving portion and be flush with the opening of the receiving portion.

[0051] Exemplarily, the product 20 can be placed in the packaging box. When the first housing 11 is in the first position, the packaging box is in a closed state. The product 20 can be located between the fastening film 12 and the buffer structure 13. At this time, the fastening film 12 can apply a force towards the buffer structure 13 to the product 20, so as to clamp the product 20 through the fastening film 12 and the buffer structure 13. That is, during the process of packaging the product 20, the product 20 can be placed on the buffer structure 13 of the second housing 14, and the first housing 11 is rotated to make the fastening film 12 fit with the side of the product 20 facing away from the buffer structure 13, so that the fastening film 12 and the buffer structure 13 can clamp and fix the product 20 located between them, avoiding the phenomenon that the product 20 shakes in the packaging box during the transportation of the product 20.

[0052] When the user needs to use the product 20, the first housing 11 can be rotated to make the packaging box in an open state, so as to facilitate the user to take out the product 20 from the packaging box. Since the first housing 11 and the second housing 14 are rotatably connected, the first housing 11 and the second housing 14 will not be completely separated, and the integrity of the packaging box can be maintained. When the user needs to place the product 20 back into the packaging box again, the product 20 can be directly placed back into the packaging box, and the first housing 11 is rotated to close the packaging box. Compared with the solution in the related art where the first housing 11 and the second housing 14 are separately arranged, in the embodiment of the present utility model, when the user closes the packaging box, there is no need to align the first housing 11 and the second housing 14, which can reduce the difficulty of closing the packaging box.

[0053] In summary, the embodiment of the present utility model provides a packaging box, including a first housing, a fastening film, a buffer structure and a second housing. When the packaging box is in a closed state, the product can be located between the fastening film and the buffer structure. At this time, the fastening film can apply a force towards the buffer structure to the product, so as to clamp and fix the product through the fastening film and the buffer structure, avoiding the phenomenon that the product shakes in the packaging box during the transportation of the product, and enhancing the protection function of the packaging box.

[0054] Please refer to Figure 4 and Figure 5 , Figure 4 is a schematic structural diagram of a first housing 11 and a fastening film 12 provided by the embodiment of the present utility model, Figure 5 is Figure 4A schematic cross-sectional structure diagram of the first housing 11 and the fastening film 12 shown along the A1-A2 position. In an alternative embodiment, the first housing 11 may include a first frame 111 and a first clamping frame 112, and the first frame 111 may be clamped with the first clamping frame 112; the edge portion of the fastening film 12 may be located at the connection position of the first frame 111 and the first clamping frame 112, and the edge portion of the fastening film 12 is located between the first clamping frame 112 and the first frame 111 and is in contact with the first clamping frame 112 and the first frame 111 respectively. The first frame 111 and the first clamping frame 112 may clamp the edge portion of the fastening film 12 to fix the fastening film 12 on the first housing 11. In this way, the installation and disassembly difficulty of the fastening film 12 can be reduced. Compared with the scheme of bonding the edge portion of the fastening film 12 to the first housing 11, the first frame 111 and the first clamping frame 112 can clamp the edge portion of the fastening film 12 to fix the fastening film 12. In the case where the fastening film 12 is damaged, the fastening film 12 can be replaced relatively easily.

[0055] Please refer to Figure 5 , in an alternative embodiment, the first frame 111 may include a first annular bottom plate 1111 and a first side plate 1112, and the first side plate 1112 is connected to the inner edge of the first annular bottom plate 1111; the first clamping frame 112 includes a second annular bottom plate 1121 and a second side plate 1122, and the second side plate 1122 is connected to the inner edge of the second annular bottom plate 1121; the second side plate 1122 may be located on one side of the first side plate 1112 close to the outer edge of the first annular bottom plate 1111, and the second side plate 1122 abuts against the first side plate 1112; the edge portion of the fastening film 12 is located between the first side plate 1112 and the second side plate 1122.

[0056] One side of the edge portion of the fastening film 12 may be attached to the side of the second side plate 1122 close to the first side plate 1112, and the other side of the edge portion of the fastening film 12 may be attached to the side of the first side plate 1112 close to the second side plate 1122. That is, the second side plate 1122 may press the edge portion of the fastening film 12 against the first side plate 1112 to improve the connection stability between the fastening film 12 and the first housing 11 and prevent the tension state of the fastening film 12 from failing.

[0057] Please refer to Figure 5 and Figure 6 , Figure 6This is a schematic projection diagram of the structure of a first clamping frame 112 provided in an embodiment of the present invention. In an optional embodiment, the second side plate 1122 of the first clamping frame 112 has a plurality of connecting posts 1123 on a side facing away from the second annular base plate 1121 of the first clamping frame 112. The edge portion of the fastening membrane 12 has a plurality of connecting posts 1123 corresponding to a plurality of connecting through holes (not shown in the figure), and the connecting posts 1123 are located in the corresponding connecting through holes.

[0058] When connecting the fastening film 12 to the first housing 11, the multiple connecting through holes in the edge portion of the fastening film 12 can be inserted one by one onto the multiple connecting posts 1123 of the first clamping frame 112, so that the edge portion of the fastening film 12 is connected to the second side plate 1122 of the first clamping frame 112. Then, the second side plate 1122 of the first clamping frame 112 connected to the fastening film 12 is assembled on the side of the first side plate 1112 of the first frame 111 to fix the fastening film 12 to the first housing 11. In this way, the connection between the fastening film 12 and the first housing 11 can be made more stable, and the fastening film 12 and the first housing 11 can be prevented from being separated.

[0059] In an exemplary embodiment, please refer to Figure 7 , Figure 7 yes Figure 4 Another cross-sectional structural diagram of the first shell 11 and the fastening membrane 12 along the position A1-A2 is shown in FIG. Figure 7 As shown, the first side plate 1112 of the first frame 111 has a plurality of protruding structures t1 on one side close to the second side plate 1122 of the first clip frame 112; the second side plate 1122 of the first clip frame 112 can abut against the protruding structures t1. Alternatively, for example, an angle is provided between the first side plate 1112 of the first frame 111 and the second side plate 1122 of the first clip frame 112, that is, the extension directions of the first side plate 1112 of the first frame 111 and the second side plate 1122 of the first clip frame 112 are not completely parallel, both of which can make the abutment between the first side plate 1112 of the first frame 111 and the second side plate 1122 of the first clip frame 112 tighter, and enable the second side plate 1122 of the first clip frame 112 to press the edge portion of the fastening film 12 against the first side plate 1112 of the first frame 111, thereby avoiding an unstable connection between the fastening film 12 and the first shell 11. In this way, the connection between the fastening film 12 and the first shell 11 can be further made more stable, and the fastening film 12 and the first shell 11 can be prevented from being separated.

[0060] Please refer to Figure 8 、 Figure 9 and Figure 10 , Figure 8 This is a structural diagram of a second shell 14 and a buffer structure 13 provided by an embodiment of the present utility model.Figure 9 is Figure 8 A schematic cross-sectional structure diagram of the second housing 14 and the buffer structure 13 along the B1-B2 position shown in Figure 10 is a schematic diagram of a buffer structure 13 provided by an embodiment of the present invention. In an optional embodiment, a buffer structure 13 is provided in the packaging box to reduce the impact external force and vibration external force transmitted to the product 20, thereby playing a role in protecting the product 20. The buffer structure 13 may include a stacked first buffer layer 131 and a second buffer layer 132. The first buffer layer 131 is located on the side of the second buffer layer 132 close to the fastening film 12; the first buffer layer 131 includes a plurality of buffer blocks 1311, and one surface of the plurality of buffer blocks 1311 close to the second buffer layer 132 is connected to the second buffer layer 132. When the product 20 is placed between the buffer structure 13 and the fastening film 12, since the fastening film 12 can apply a force towards the buffer structure 13 to the product 20 to position the product 20 in a direction perpendicular to the first buffer layer 131, plus the self-weight of the product 20 itself, a plurality of buffer blocks 1311 in the area where the product 20 contacts the buffer structure 13 can generate compressive deformation, and the shapes of the plurality of buffer blocks 1311 that do not contact the product 20 may not change. Thus, the height of the buffer block 1311 after compressive deformation is less than the height of the undeformed buffer block 1311, and the undeformed buffer block 1311 can play a limiting effect on the product 20, that is, position the product 20 in a direction parallel to the first buffer layer 131, which can further improve the protection effect of the buffer structure 13 on the product 20.

[0061] Exemplarily, the material of the fastening film 12 may include at least one of polyethylene (English: polyethylene; abbreviation: PE) and polyurethane (English: Polyurethane; abbreviation: PU).

[0063] Please refer to Figure 10, in an alternative embodiment, the orthographic projection of the buffer block 1311 in the buffer structure 13 on the second buffer layer 132 may be polygonal; and the areas and shapes of the orthographic projections of the plurality of buffer blocks 1311 on the second buffer layer 132 are the same. Exemplarily, the orthographic projection of the buffer block 1311 on the second buffer layer 132 may be square, which can make the arrangement of the plurality of buffer blocks 1311 relatively compact, so that the force between the plurality of buffer blocks 1311 of the buffer structure 13 and the product 20 is relatively uniform.

[0064] Please refer to Figure 8 , in an alternative embodiment, in the thickness direction of the buffer structure 13, the thickness of the buffer structure 13 is the same as the depth of the accommodating portion. In this way, when the packaging box is in the closed state, the buffer structure 13 and the fastening film 12 can clamp the product 20, strengthening the protection of the product 20 by the packaging box.

[0065] Please refer to Figure 11 、 Figure 12 and Figure 13 , Figure 11 is a schematic structural diagram of a first housing 11 provided by an embodiment of the present invention, Figure 12 is a schematic structural diagram of a second housing 14 provided by an embodiment of the present invention, Figure 13 is a schematic structural diagram of another packaging box provided by an embodiment of the present invention.
