Description

Technical Field

[0001] The utility model relates to a protective case, and in particular to a double-shell connection structure for a folding mobile phone. Background Art

[0002] With the gradual popularization of folding mobile phones, folding mobile phone protective cases that provide effective protection for them have emerged as the times require. Commonly seen folding mobile phone protective cases on the market usually consist of three parts, namely a bottom shell, a middle-axis shell and a face shell. The bottom shell, the middle-axis shell and the face shell are rotationally connected by a pin shaft. Although this design meets the protection requirements of folding mobile phones to a certain extent, there are also some obvious defects and deficiencies.

[0003] First of all, the design structure of the pin shaft connection is complex, and both installation and disassembly are rather troublesome. In addition, since the pin shaft connection requires sufficient space to be reserved between the bottom shell and the middle-axis shell to ensure smooth rotation and folding, this increases the thickness of the overall protective case, affecting the user experience and feel.

[0004] In order to simplify the structure of the protective case and improve the user experience, some designs omit the face shell and only complete the flexible connection between the bottom shell and the middle-axis shell through skin pasting. This design connected by skin pasting, although simplifies the structure of the protective case to a certain extent and reduces the thickness, brings new problems.

[0005] First of all, the middle-axis shell connected by skin pasting has poor elastic ability. Since the skin pasting is exposed outside, it is easily affected by the external environment, such as scratching and abrasion, resulting in damage to the skin pasting, and further affecting the flexible connection between the bottom shell and the middle-axis shell, reducing the service life of the protective case. In addition, after long-term use, the flexible connection by skin pasting is prone to situations such as peeling or breaking of the leather surface, which not only affects the aesthetics of the protective case, but also further reduces its protection performance.

[0006] Secondly, the connection by skin pasting has a higher risk of damage due to the large exposed area of the leather surface. Once the skin pasting is damaged, not only the entire skin pasting part needs to be replaced, increasing the maintenance cost, but also the production cost is greatly increased. The middle-axis shell connected by skin pasting is prone to fatigue damage due to frequent folding during long-term use, further affecting its elasticity and stability. Summary of the Invention

[0007] In order to solve the above problems, the utility model provides a double-shell connection structure for a folding mobile phone, using TPU as the connecting piece of the two shells, effectively solving the deficiencies in the prior art.

[0009] A middle shaft shell, which has a middle shaft installation cavity, and the middle shaft shell is elastically connected to the splicing opening surface of the bottom shell through an elastic connecting piece;

[0010] When the external electronic device is installed in the device installation cavity, the central axis shell is opened, and the central axis position of the central axis shell and the external electronic device is pressed tightly by the elastic connecting piece.

[0011] As a preferred technical solution, the elastic connecting piece is made of TPU material, and two sides of the elastic connecting piece are fixedly bonded to the bottom shell and the middle shaft shell respectively.

[0012] As a preferred technical solution, the splicing opening surface of the bottom shell has a first assembly groove, the middle shaft shell has a second assembly groove relative to the first assembly groove, and the two sides of the elastic connecting piece are respectively inserted into the first assembly groove and the second assembly groove and fixed with glue.

[0014] As a preferred technical solution, a magnetic suction groove is provided on one side of the middle shaft shell opposite to the bottom shell, and magnetic suction blocks are installed in the magnetic suction grooves.

[0015] As a preferred technical solution, the elastic connecting piece is an elastic connecting piece of any shape.

[0016] The beneficial effects of the utility model are as follows: the utility model simplifies the structure of the protective shell by using the elastic connecting piece, avoids the complex installation and thickness problems of the pin connection, and improves the user experience;

[0017] Secondly, the elastic connecting piece made of TPU material provides good elasticity and toughness, so that the middle shaft shell can be stretched and tightly compressed when installing external electronic equipment, which improves the stability and durability of the protective shell;

[0027] like Figure 1 As shown, a double-shell connection structure of a foldable mobile phone of the utility model comprises a bottom shell 2, wherein the bottom shell 2 has a device installation cavity, and one of the side surfaces of the bottom shell 2 forms a splicing opening surface 6. In this embodiment, the electronic device may be a foldable mobile phone, which is installed in the device installation cavity. When the foldable mobile phone is folded, the central axis position of the foldable mobile phone is located in the splicing opening surface 6;

[0028] It also includes a middle shaft shell 1, which has a middle shaft installation cavity 5, and the middle shaft shell 1 is elastically connected to the splicing opening surface 6 of the bottom shell 2 through an elastic connecting piece 3;

[0029] When the external electronic device is installed in the device installation cavity, the central axis shell 1 is opened, and the elastic connecting piece 3 presses the central axis position of the central axis shell 1 and the external electronic device.

[0030] In this embodiment, the elastic connecting piece 3 is made of TPU material, and the two sides of the elastic connecting piece 3 are fixedly bonded to the bottom shell 2 and the middle axis shell 1 respectively.

In this embodiment, the elastic connecting piece 3 is an elastic connecting piece 3 of any shape, preferably a strip-shaped connecting piece with flat surfaces on the upper and lower sides.

[0034] The utility model simplifies the structure of the protective shell by using the elastic connecting piece 3, avoids the complex installation and thickness problems of the pin connection, and improves the user experience;

[0035] Secondly, the elastic connecting piece 3 made of TPU material provides good elasticity and toughness, so that the middle shaft shell 1 can be stretched and tightly pressed when installing external electronic equipment, thereby improving the stability and durability of the protective shell;

[0036] At the same time, the two sides of the elastic connecting piece 3 are fixedly bonded to the bottom shell 2 and the middle shaft shell 1 respectively, ensuring the firmness and reliability of the connection. In addition, the elastic connecting piece 3 is embedded in the assembly grooves of the bottom shell 2 and the middle shaft shell 1 and fixed by glue, further enhancing the stability of the structure.
