[0030] It should also be understood that the terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. As used in the specification of the present application and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include the plural forms.

[0031] It should be further understood that the term " / and" used in the specification of the present application and the appended claims refers to any combination and all possible combinations of one or more of the related listed items, and includes these combinations.

[0032] Please refer to Figures 1 - 8As shown in the figure, an embodiment of the present application provides a packing box 100, which includes a box body 10 and a wheel assembly 20. The box body 10 includes a bottom wall 10a. The box body 10 is provided with a first groove 11 that is recessed from the bottom wall 10a towards the inner side of the box body 10. The first groove 11 forms a first opening 111 at the bottom wall 10a. A wheel assembly 20 is provided at the first groove 11. The wheel assembly 20 includes a fixing structure 21, a rotating structure 22, and a wheel 23. The fixing structure 21 is installed on the box body 10. The rotating structure 22 is rotatably connected to the fixing structure 21 to rotate and switch between a first state and a second state. The wheel 23 is rotatably connected to the rotating structure 22. When the rotating structure 22 rotates to the first state, it drives the wheel 23 to extend out of the outer side of the bottom wall 10a through the first opening 111 to assist the movement of the box body 10. When the rotating structure 22 rotates to the second state, it drives the wheel 23 to rotate towards the inner side of the bottom wall 10a to retract into the first groove 11.

[0033] The packing box 100 provided by the embodiment of the present application, through the setting of the wheel assembly 20, can rotate to make the wheel 23 extend out of the bottom wall 10a, so that the wheel 23 can be used to assist the movement of the box body 10, without the assistance of a forklift, a trolley or similar instruments for transportation, improving the portability of transportation. When the transportation is completed, the wheel 23 can be retracted into the first groove 11 to form a folded state, reducing the volume of the box body 10 and the occupied space.

[0034] Exemplarily, the shape of the first groove 11 can be rectangular or other shapes, as long as it can adapt to the wheel assembly 20 to accommodate the wheel assembly 20.

[0035] In some embodiments, as Figures 1 - 3 shown, the box body 10 further includes a first side wall 10b adjacent to the bottom wall 10a. The first groove 11 is located at the included angle between the bottom wall 10a and the first side wall 10b. The first groove 11 forms a second opening 112 at the first side wall 10b. The first opening 111 is communicated with the second opening 112. When the wheel 23 retracts into the first groove 11, it faces the second opening 112. Through the above setting, it is convenient for the user to operate the wheel assembly 20 through the first opening 111 and the second opening 112 to drive the wheel 23 to rotate to extend out of the bottom wall 10a or retract into the first groove 11. At the same time, through the communication setting of the second opening 112 and the first opening 111, the first groove 11 has a larger opening, which is convenient for the processing of the first groove 11 in the box body 10 and the installation of the wheel assembly 20.

[0036] In some embodiments, as Figures 1 - 5As shown, the box body 10 further includes a top wall 10c opposite to the bottom wall 10a in a first direction, a second side wall 10d opposite to the first side wall 10b in a second direction, and a third side wall 10e and a fourth side wall 10f oppositely arranged in a third direction. The first direction, the second direction, and the third direction are perpendicular to each other pairwise. In specific applications, such as Figure 4 and Figure 5 shown, the first direction may be the height direction of the box body 10, the second direction may be the length direction of the box body 10, and the third direction may be the width direction of the box body 10.

[0037] In some embodiments, such as Figures 1 - 3 、 Figure 5 shown, the number of the first grooves 11 is two, and the two first grooves 11 are arranged at intervals along the width direction of the box body 10, that is, the two first depressions are arranged at intervals along the third direction. Wheel assemblies 20 are provided in both of the two first grooves 11. Through the arrangement of the two first grooves 11, two wheel assemblies 20 can be provided on one side of the box body 10 to improve the stability of the transportation of the box body 10.

[0038] Of course, in other embodiments, only one first groove 11 and one wheel assembly 20 may be provided, or three or more first grooves 11 and wheel assemblies 20 may be provided.

[0039] In some embodiments, such as Figure 5 and Figure 8 shown, in each of the two wheel assemblies 20, a positioning hole 210 is provided in the fixing structure 21 of each wheel assembly 20. The packaging box 100 further includes a fixing rod 30, and the fixing rod 30 is used to connect to the positioning holes 210 of the fixing structures 21 of the two wheel assemblies 20 to maintain the relative positions of the two wheel assemblies 20. Through the arrangement of the positioning holes 210 and the fixing rod 30, it is helpful to maintain the relative positions of the two wheel assemblies 20, so as to ensure that the two wheel assemblies 20 are parallel to each other, so that the two wheels 23 are coaxially opposite, and the stability of the box body 10 during movement is improved.

[0040] In some embodiments, such as Figures 6 - 8As shown, the fixing structure 21 includes a main body 211, a hinge portion 212 and a bending portion 213. The main body 211 is installed on the box body 10. The hinge portion 212 is connected to one side in the extending direction of the main body 211, and the bending portion 213 is connected to the other side in the extending direction of the main body 211. The hinge portion 212 is rotatably connected to the rotating structure 22, so that the rotating structure 22 can rotate and switch between a first state and a second state relative to the hinge portion 212. Among them, the bending portion 213 is bent relative to the main body 211 to be clamped at a preset position of the box body 10. Exemplarily, the preset position may be a corresponding buckle position on the bottom wall 10a of the box body 10. Through the setting of the bending portion 213, it can be clamped at the corresponding buckle position of the box body 10, thereby improving the connection stability between the fixing structure 21 and the box body 10.

[0041] In some embodiments, as Figure 8 shown, the main body 211 may be in a plate-like structure, including a main board 2111 and side boards 2112 extending from both sides of the main board 2111. The positioning holes 210 may be provided at the side boards 2112 of the main body 211. The main board 2111 of the main body 211 can be fixed to the box body 10 by means of pasting, screwing or buckling, etc., and then clamped to the box body 10 through the bending portion 213, so as to fixedly connect the fixing structure 21 and the box body 10, thereby enhancing the overall stability of the packaging box 100.

[0042] In some embodiments, in the direction from the fixing structure 21 to the rotating structure 22, the vertical thickness of the side board 2112 gradually increases to facilitate the connection of the hinge portion 212, thereby facilitating the rotational connection with the rotating structure 22.

[0043] In some embodiments, the main body 211, the hinge portion 212 and the bending portion 213 are integrally formed, the structure is more stable, and the integrated setting reduces the assembly steps.

[0044] In some embodiments, as Figures 6 - 8As shown, the wheel assembly 20 further includes a rotating shaft 24. The rotating structure 22 includes a support base 221 and a first rotating part 222 and a second rotating part 223 provided at both ends in the extending direction of the support base 221. The extending direction of the support base 221 is parallel to the axial direction of the rotating shaft 24. The first rotating part 222 has a first end 2221 facing the fixed structure 21 and a second end 2222 opposite to the first end 2221. The second rotating part 223 has a third end 2231 facing the fixed structure 21 and a fourth end 2232 opposite to the third end 2231. Among them, the rotating shaft 24 is movably inserted through the hinge part 212 of the fixed structure 21 and the first end 2221 and the third end 2231, so that the rotating structure 22 can rotate relative to the fixed structure 21. The wheel 23 is rotatably connected between the second end 2222 and the fourth end 2232. Thus, the rotation of the rotating structure 22 can drive the wheel 23 to extend out of the bottom wall 10a or retract into the first groove 11, and the wheel 23 can rotate when it extends out of the bottom wall 10a to assist the movement of the box body 10.

[0045] Exemplarily, the hinge part 212 of the fixed structure 21 includes a first hinge part 2121 opposite to the first rotating part 222 and a second hinge part 2122 opposite to the second rotating part 223. The first end 2221 of the first rotating part 222 and the third end 2231 of the second rotating part 223 can be respectively located on the opposite sides of the first hinge part 2121 and the second hinge part 2122, or can be respectively located on the opposite sides of the first hinge part 2121 and the second hinge part 2122 and are connected by the rotating shaft 24 to realize the relative rotation between the fixed structure 21 and the rotating structure 22.

[0046] Optionally, damping structures such as damping gaskets can also be provided on both axial sides of the first rotating part 222 and the second rotating part 223, so that there is resistance when the first rotating part 222 and the second rotating part 223 rotate synchronously, realizing the damping effect, and thus the rotation angle of the rotating structure 22 can be controlled.

[0047] It should be noted that, as Figures 1 - 5As shown, the first groove 11 and the wheel assembly 20 provided in the first groove 11 can be arranged on only one side of the box body 10. When it is necessary to move the box body 10, one side of the box body 10 can be lifted and pushed and pulled unilaterally. Of course, the first groove 11 is not limited to being arranged on only one side of the box body 10. For example, in some other embodiments, the first groove 11 is located at the included angle between the bottom wall 10a and the first side wall 10b. The box body 10 is provided with a second groove at the included angle between the bottom wall 10a and the second side wall 10d. The second groove and the first groove 11 are axially symmetric structures, and the wheel assembly 20 is provided at the second groove. By respectively arranging the first groove 11 and the second groove on both sides of the bottom wall 10a of the box body 10 in the second direction, and arranging the wheel assemblies 20 in both the first groove 11 and the second groove, the movement of the box body 10 is made more balanced.

[0048] In some embodiments, when the rotating structure 22 rotates to the first state, the rotating structure 22 is perpendicular to the bottom wall 10a, so as to facilitate the wheel 23 to abut against the ground for support, thereby facilitating the auxiliary movement of the box body 10. When the rotating structure 22 rotates to the second state, the rotating structure 22 is parallel to the bottom wall 10a. Thus, the wheel 23 can be retracted into the first groove 11. In specific applications, when the wheel 23 extends out of the bottom wall 10a, the rotating structure 22 is perpendicular to the bottom wall 10a, so that the wheel 23 can stably contact the ground and improve the stability during transportation. When the wheel 23 retracts into the first groove 11, the rotating structure 22 is parallel to the bottom wall 10a, thereby avoiding protruding outside the box body 10, maintaining the flatness of the outer wall of the box body 10, and reducing the occupied space.

[0049] In some embodiments, the packaging box 100 further includes a locking structure (not shown in the figure). The locking structure is used to lock when the rotating structure 22 rotates to the first state or the second state, so as to keep the rotating structure 22 in the first state or the second state. When the rotating structure 22 rotates to the first state or the second state, it can be locked through the locking structure to limit the rotation of the rotating structure 22, so as to keep the wheel 23 extending out of the bottom wall 10a or retracting into the first groove 11, thereby avoiding the rotation of the rotating structure 22 to drive the wheel 23 to retract when the box body 10 moves. When the rotating structure 22 needs to be switched from the first state to the second state, or from the second state to the first state, the locking structure can be unlocked, so that the rotating structure 22 can rotate to drive the wheel 23 to rotate to extend out of the bottom wall 10a or retract into the first groove 11.

[0050] Optionally, the locking structure can include a magnetic attraction member and / or a buckle member. The rotating structure 22 is locked or unlocked through the magnetic attraction member and / or the buckle member. The magnetic attraction member can be the magnetic attraction cooperation between magnets or the magnetic attraction cooperation between a magnet and a metal member. The buckle member can be the buckle cooperation between a protrusion and a card slot or the buckle cooperation between two buckles.

[0051] As an implementation manner, magnetic attraction members or snap members can be provided at corresponding positions of the rotating structure 22 and the box body 10, so that when the rotating structure 22 rotates to the first state or the second state, the magnetic attraction members of the two can adsorb each other, or the snap members of the two can be snap-connected to realize the locking of the rotating structure 22.

[0052] As another implementation manner, a locking structure can be provided at the rotating connection between the rotating structure 22 and the fixed structure 21. A sliding groove can be provided on one of the rotating structure 22 and the fixed structure 21, and a protruding portion can be provided on the other of the rotating structure 22 and the fixed structure 21. When the rotating structure 22 and the fixed structure 21 rotate relative to each other, the protruding portion slides in the sliding groove to guide the relative rotation of the rotating structure 22 and the fixed structure 21. Card slots with a deeper depth can be provided at both ends of the extending direction of the sliding groove, so that when the rotating structure 22 rotates to the first state and the second state, the protruding portion is respectively located in the two card slots in the extending direction of the sliding groove to realize locking. When unlocking is required, a relatively large external force is needed to disengage the protruding portion from the card slot to realize unlocking.

[0053] Of course, magnetic attraction members can also be provided in the two card slots of the sliding groove, and the protruding portion can be set as a structure such as metal that can be adsorbed by the magnetic attraction members, so as to improve the locking effect.

[0054] In some embodiments, both the rotating structure 22 and the fixed structure 21 can be made of plastic material. The plastic structure is light in weight, convenient to process, and low in cost. Of course, in other embodiments, the rotating structure 22 and the fixed structure 21 can also be made of metal or other materials.

[0055] In some embodiments, the box body 10 is a cardboard box. The cardboard box packaging has the characteristics of easy material collection, light weight, easy printing, easy design and molding, low cost, etc. Of course, in other embodiments, the box body 10 can also be a wooden box, a plastic box, etc.

[0056] Without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.

[0057] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
