A mobile phone is a mobile terminal equipped with a cellular communication module.

[0022] like Figure 2As shown, a mobile terminal packaging box 10 of an embodiment includes a box body 100 and a storage rack 300 accommodated in the box body 100. A mobile terminal (not shown) and a mobile terminal protective shell 20 can be placed on the storage rack 300. The box body 100 includes an upper cover 110 and a lower cover 120, and the upper cover 110 and the lower cover 120 cooperate to form a space for accommodating the storage rack 300.

[0023] Combination Figure 2 , Figure 3 and Figure 4 As shown, specifically, the storage rack 300 has a first surface 310. A storage cavity 320 with an open end is formed on the storage rack 300, and the opening 321 of the storage cavity 320 is located on the first surface 310. The storage cavity 320 has a storage cavity bottom wall 322 and a storage cavity side wall 323. The storage cavity bottom wall 322 is formed with a storage groove 330 connected to the storage cavity 320, and the storage groove 330 is annular. The mobile terminal protective shell 20 includes a protective shell bottom wall 21 and a protective shell side wall 22, and the protective shell side wall 22 is arranged around the periphery of the protective shell bottom wall 21. The protective shell side wall 22 can be accommodated in the storage groove 330, the protective shell bottom wall 21 can abut against the storage cavity bottom wall 322, and the mobile terminal can be accommodated in the storage cavity 320. When accommodated in the storage cavity 320, the mobile terminal is located on the side of the protective shell bottom wall 21 away from the storage cavity bottom wall 322. In this way, when subjected to squeezing, the protective shell bottom wall 21 of the mobile terminal protective shell 20 can be stably pressed against the bottom wall 322 of the accommodating cavity without deformation, thereby achieving effective protection of the mobile terminal protective shell 20.

[0024] In addition, the upper cover 110 and the lower cover 120 are respectively formed by bending and bonding a piece of corrugated cardboard. The corrugated cardboard is a multi-layer adhesive body composed of a layer of corrugated core paper and two layers of cardboard, which has high mechanical strength and can withstand collisions and falls during transportation, thereby providing good protection for the mobile terminal and the mobile terminal protective shell 20 contained therein.

[0025] In addition, the depth H1 of the storage groove 330 is greater than or equal to the height H2 of the protective shell side wall 22, so that the protective shell side wall 22 can be fully extended into the storage groove 330 to prevent the protective shell side wall 22 from deforming due to the force between the protective shell side wall 22 and the storage groove bottom wall 331. It should be pointed out that the depth of the storage groove 330 is the distance between the storage groove bottom wall 331 and the accommodating cavity bottom wall 322. The height of the protective shell side wall 22 is the height of the protective shell side wall 22 beyond the surface of the protective shell bottom wall 21.

[0026] In addition, combined Figure 1 and Figure 3As shown, the width D1 of the storage groove 330 is greater than or equal to the thickness D2 of the protective shell side wall 22, so as to avoid the abutment between the storage groove side wall 332 and the protective shell side wall 22 after the protective shell side wall 22 is fully extended into the storage groove 330, thereby preventing the protective shell side wall 22 from deforming due to the abutment between the storage groove side wall 332 and the protective shell side wall 22. It should be pointed out that the width of the storage groove 330 is the distance between the two storage groove side walls 332. The projection of the protective shell side wall 22 on the plane where the protective shell bottom wall 21 is located is annular, wherein the annular projection has an inner ring and an outer ring, and the maximum distance between the inner ring and the outer ring is the thickness of the protective shell side wall 22.

[0027] Specifically, a storage groove side wall 332 located on the periphery of the storage groove 330 is flush with the side wall 323 of the accommodating cavity, so that the storage groove 330 is located at the edge of the bottom wall 322 of the accommodating cavity. In this way, the accommodating cavity 320 can have a smaller volume while meeting the requirements of accommodating the mobile terminal and the mobile terminal protective shell 20, avoiding space waste in the accommodating cavity 320, and also making the structural design of each component in the accommodating cavity 320 more compact.

[0028] Combination Figure 3 to Figure 4 As shown, in one embodiment, a first receiving groove 340 is further formed on the bottom wall 322 of the accommodating cavity, and the first receiving groove 340 is located in the annular area surrounded by the storage groove 330, that is, the first receiving groove 340 is located on the bottom wall 322 of the accommodating cavity in the annular area surrounded by the storage groove 330. Specifically, the first receiving groove 340 has a first receiving groove bottom wall 341 and a first receiving groove side wall 342, and the accommodating cavity bottom wall 322, the first receiving groove side wall 342 and the first receiving groove bottom wall 341 together form a step-like structure. The first receiving groove 340 is rectangular, and the first receiving groove 340 is used to place the instruction manual of the mobile terminal. The setting of the first receiving groove 340 not only provides a storage space for the instruction manual of the mobile terminal, but also, after the instruction manual of the mobile terminal is placed in the first receiving groove 340, the instruction manual of the mobile terminal can abut against the bottom wall 21 of the protective shell 20 of the mobile terminal protective shell to support the bottom wall 21 of the protective shell.

[0029] In addition, a second receiving groove 350 is formed on the bottom wall 341 of the first receiving groove, and the second receiving groove 350 is used to accommodate mobile terminal accessories such as a charger and a data cable. Specifically, the second receiving groove 350 is cylindrical.

[0030] In one embodiment, the mobile terminal packaging box 10 further includes a support member 500, on which a receiving space 510 for receiving the mobile terminal is formed, and the support member 500 can be received in the receiving cavity 320 and movably connected to the receiving cavity side wall 323. By providing the support member 500, not only can the mobile terminal be supported and received, but also the mobile terminal and the mobile terminal protective shell 20 can be isolated to prevent the flexible mobile terminal protective shell 20 from directly contacting and adhering to the mobile terminal.

[0031] Furthermore, the side wall 323 of the accommodating cavity has a step portion 324 located at the opening 321 of the accommodating cavity 320, and the support member 500 includes a first support portion 520, a second support portion 530 and a connecting portion 540. The first support portion 520 is in the shape of a plate, and the connecting portion 540 is connected to the periphery of the first support portion 520, and together with the first support portion 520, it forms a receiving space 510, and the second support portion 530 is connected to the side of the connecting portion 540 that is away from the receiving space 510. The second support portion 530 can abut against the step portion 324. In this way, the step portion 324 can support the support member 500 and the mobile terminal accommodated in the receiving space 510, thereby realizing the connection between the support member 500 and the inner wall of the accommodating cavity 320.

[0032] Combination Figure 1 and Figure 3 As shown, after the support member 500 is installed on the side wall 323 of the accommodating cavity, that is, when the second support portion 530 abuts against the step portion 324, the distance D3 between the first support portion 520 and the bottom wall 322 of the accommodating cavity is greater than or equal to the thickness D4 of the bottom wall 21 of the protective shell. In this way, not only can there be space between the first support portion 520 and the bottom wall 322 of the accommodating cavity to accommodate the bottom wall 21 of the protective shell, but it can also avoid the first support portion 520 abutting against the bottom wall 21 of the protective shell and causing deformation of the mobile terminal protective shell 20, thereby protecting the mobile terminal protective shell 20.

[0033] The second support portion 530 is connected to the end of the connection portion 540 away from the first support portion 520, and the second support portion 530 is flush with the surface where the opening 321 is located, that is, the second support portion 530 is flush with the first surface 310, so as to present a better appearance effect. In addition, a through hole 550 is provided on the first support portion 520, which penetrates the first support portion 520, and a hand can be inserted into the through hole 550 to take the support member 500 out of the accommodating cavity 320. It should be pointed out that there is one through hole 550, and it is located in the middle position of the first support portion 520, so as to have a better visual effect. In other embodiments, the number of through holes 550 can also be two or more, and the position of the through hole 550 on the first support portion 520 can also be arbitrarily arranged.

[0034] In one embodiment, the storage rack 300 and the support member 500 are both made by vacuum forming, that is, by heating a flat plastic hard sheet to soften it, vacuuming it onto a mold surface, and molding it after cooling. This method has the advantages of saving raw materials, being light in weight, and having high production efficiency.

[0035] Combination Figure 3 and Figure 5 As shown, in addition, a first avoidance groove 560 connected to the receiving space 510 is formed on the connecting portion 540, and the first avoidance groove 560 can make way for the volume adjustment button or the power button on the side of the mobile terminal when the mobile terminal is placed in the receiving space 510. Since the support member 500 is made by blister molding, the outer surface of the connecting portion 540 is a structure protruding outward at the first avoidance groove 560. Therefore, a second avoidance groove 325 is formed at a position corresponding to the first avoidance groove 560 on the side wall 323 of the receiving cavity, so that the support member 500 can be smoothly installed on the side wall 323 of the receiving cavity. At the same time, the second avoidance groove 325 can also limit the support member 500. It should be pointed out that the number of the first avoidance groove 560 and the second avoidance groove 325 are both two, and the two first avoidance grooves 560 are respectively located at two relative positions of the support member 500, and the two second avoidance grooves 325 are respectively located at two relative positions of the side wall 323 of the receiving cavity.

[0036] Combination Figure 2 and Figure 4 As shown, a third receiving slot 360 for receiving headphones is formed on the storage rack 300, and the third receiving slot 360 includes a central receiving slot 361, a headphone receiving slot 362, a microphone receiving slot 363, and a connecting wire receiving slot 364. The headphone receiving slot 362 is located on one side of the central receiving slot 361, the microphone receiving slot 363 is located on the other side of the central receiving slot 361, and the microphone receiving slot 363 is connected to the central receiving slot 361, and the connecting wire receiving slot 364 connects the headphone receiving slot 362 and the microphone receiving slot 363. The headphones include headphone heads, microphones, connecting wires, and connecting plugs. The headphone receiving slot 362 is used to receive headphone heads, the microphone receiving slot 363 is used to receive microphones, the connecting wire receiving slot 364 is used to receive connecting wires between microphones and headphone heads, and the central receiving slot 361 is used to receive connecting wires between microphones and connecting plugs and connecting plugs. It should be noted that there are two earphone receiving slots 362 and two connecting wire receiving slots 364 . The two connecting wire receiving slots 364 are respectively located on opposite sides of the central receiving slot 361 and are each connected to one earphone receiving slot 362 .

[0037] The rack 300 is formed with a fourth receiving groove 370 for accommodating earphone plugs, and a plurality of earphone plug mounting positions 371 are formed in the fourth receiving groove 370. Specifically, the number of the earphone plug mounting positions 371 is an even number, and the sizes of the earphone plug mounting positions 371 can be different to adapt to earphone plugs of different sizes.

[0038] In addition, the third receiving groove 360 ​​and the fourth receiving groove 370 are located on the same side of the accommodating cavity 320 and are spaced apart from the accommodating cavity 320 . The third receiving groove 360 ​​and the fourth receiving groove 370 are spaced apart from each other, so that the structural layout of the rack 300 can be more compact.

[0039] The present application also protects a mobile terminal packaging box assembly. In one embodiment, the mobile terminal packaging box assembly includes a mobile terminal (not shown), a mobile terminal protective shell 20 and a mobile terminal packaging box 10. The mobile terminal packaging box 10 can accommodate the mobile terminal and the mobile terminal protective shell 20, thereby protecting the mobile terminal and the mobile terminal protective shell 20. In some embodiments, the mobile terminal packaging box assembly may also include one or two or more of a mobile terminal instruction manual, earphones, earphone plugs, a data cable, and a charger.

[0040] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
