[0002] Protective cases are generally used to protect devices to prevent hard objects from leaving scratches on the device screen or body. In order to better protect the device, general protective cases currently use harder composite materials to achieve better protection. However, the use of harder materials will cause the device to be difficult to install or disassemble, which is not conducive to normal use by users. At the same time, the existing protective cases are made of composite materials. Therefore, if the dimensional tolerance is not accurate, it is easy to cause the device to become loose or not fit tightly after being installed in the protective case. Therefore, it is often necessary to constantly correct the mold to achieve a complete fit with the size of the device. Utility Model Content

[0023] See also Figure 1-4 As shown, the utility model relates to a protective shell, including a hard shell 1, which serves as a skeleton support. It is not easy to assemble terminal devices such as mobile phones and IPADs (not shown in the figure) with a harder shell, and at least one shell notch 111 is provided on each shell corner 11 of the hard shell 1. When assembling the terminal device, the shell notch 111 undergoes elastic deformation, which facilitates the assembly of the terminal device into the hard shell 1.

[0024] The shell gap 111 is filled with a filling soft rubber block 211. The filling soft rubber block 211 has a certain elasticity. This not only solves the problem that the hard rubber of the hard shell 1 is not easy to install, but also makes it more convenient for users to assemble and disassemble, making the hard shell 1 more comprehensive and protective without leaving any gaps. After filling the filling soft rubber block 211, the shell gap 111 is filled, no discomfort is felt, and it is more comfortable to hold.

[0025] Although the hard shell 1 is relatively hard and can better protect the mobile phone, after the terminal device is assembled in the hard shell 1, there is an assembly gap between the side wall of the terminal device and the inner wall of the hard shell 1, resulting in looseness and loose fit. Therefore, it is often necessary to constantly modify the mold to achieve full size compliance with the device, resulting in a high defect rate;

[0026] In order to avoid looseness after assembly, the inner side wall surface of the hard shell 1 is provided with an injection molding groove 14, and the soft inner frame 2 is injection molded in the injection molding groove 14. After the inner side wall of the hard shell 1 is filled with the soft inner frame 2, since the soft inner frame 2 has a certain tolerance and error tolerance size, a slight deviation in the size will not cause the device (such as a mobile phone or other mobile terminal) to become loose, thereby improving the yield of the preparation and improving the impact resistance of the protective shell to the device. When falling or being impacted, the soft inner frame 2 absorbs energy and reduces the damage to the device.

[0027] Furthermore, in this embodiment, the hard shell 1 is preferably made of a generally harder material. The hard shell 1 can effectively protect the device from damage caused by friction, wear, collision and falling during use. The preferred material of the hard shell 1 is: Kevlar (aramid fiber composite material), or it can be a composite material such as carbon fiber, glass fiber, plant fiber, chemical fiber, etc.

[0028] In this embodiment, the hard shell 1 includes a shell bottom 12 and a frame 13. The shell bottom 12 is a quadrilateral in shape. The frame 13 is arranged around the outline of the shell bottom 12. The inner wall of the frame 13 is provided with an injection molding groove 14. The injection molding groove 14 is used to assemble with the soft inner frame 2. The frame 13 after surrounding forms four shell corners 11 due to the outline of the shell bottom 12. Each of the diagonal corners is provided with at least one shell notch 111. The shell notch 111 is rectangular in shape. The shell notch 111 improves the elasticity of the hard shell 1 and facilitates the installation or removal of the device.

[0029] Furthermore, in this embodiment, the soft inner frame 2 is preferably made of a generally soft and elastic material. The elastic material used in the soft inner frame 2 has a certain tolerance and error tolerance size. A slight deviation in the size will not cause the device to loosen, thereby improving the yield of the preparation. In addition, the soft inner frame 2 also improves the impact resistance of the protective shell to the device. When it falls or is impacted, the elastic material of the soft inner frame 2 absorbs energy and reduces damage to the device. The preferred material of the soft inner frame 2 is: TPU, TPE, TPX, TPV, TPSiv, silicone / liquid silicone and other plastic silicone / liquid silicone and other elastic compounds.

[0030] In this embodiment, the outer contour of the soft inner frame 2 matches the injection molding groove 14, and the soft inner frame 2 has four inner frame corners 21, and each inner frame corner 21 is provided with a filling soft rubber block 211, and the filling soft rubber block 211 is integrally injection molded with the soft inner frame 2, and the material of the filling soft rubber block 211 is consistent with the inner frame corner 21, and the filling soft rubber block 211 protrudes from the outer peripheral surface of the soft inner frame 2, and the shape and position of the filling soft rubber block 211 match the shell gap 111. When the soft inner frame 2 is set in the injection molding groove 14 of the hard shell 1, the filling soft rubber block 211 fills the shell gap 111. When the device is installed or removed from the protective shell, the filling soft rubber block 211 can provide elasticity due to the use of soft rubber material, so that the device can be more easily installed inside the protective shell through the corners.

[0031] In this embodiment, the frame 13 of the hard shell 1 is provided with a first button hole 15, a second button hole 16, a first shell plug hole 17, a second shell plug hole 18, and a third shell plug hole 19. The soft inner frame 2 is provided with a first key adhesive layer 22, a second key adhesive layer 23, a first inner frame plug hole 24, a second inner frame plug hole 25, and a third inner frame plug hole 26. The first key adhesive layer 22, the second key adhesive layer 23, the first inner frame plug hole 24, the second inner frame plug hole 25, and the third inner frame plug hole 26 are matched with the positions of the first button hole 15, the second button hole 16, the first shell plug hole 17, the second shell plug hole 18, and the third shell plug hole 19 in sequence. When the soft inner frame 2 is set in the injection molding groove 14 of the hard shell 1, the first button glue layer 22 is exposed to the hard shell 1 through the first button hole 15, and the second button glue layer 23 is exposed to the hard shell 1 through the second button hole 16, and the first inner frame hole 24, the second inner frame hole 25 and the third inner frame hole 26 overlap with the first shell hole 17, the second shell hole 18 and the third shell hole 19 respectively.

[0032] In this embodiment, inner frame notches 27 are provided on both sides of each of the inner frame corners 21 , the first button adhesive layer 22 , the second button adhesive layer 23 , the first inner frame inserting hole 24 , the second inner frame inserting hole 25 and the third inner frame inserting hole 26 .

[0033] The following is a manufacturing process of a protective case of the utility model: first, a hard shell 1 in the form of a mobile phone shell is prepared and stacked by hard materials, and a shell notch 111 is cut out at the shell corner 11 of the hard shell 1 by laser cutting or CNC machine tool processing. Then, the hard shell 1 is placed in a mold, and the elastic material is injected into the mold to make the hard shell 1 and the soft inner frame 2 injection molded, and the filling soft rubber block 211 of the soft inner frame 2 fills the shell notch 111 of the hard shell 1, and finally it is cooled and taken out from the mold, thereby obtaining a finished protective case.

[0034] The utility model relates to a protective shell, which comprises a hard shell 1 and a soft inner frame 2. The hard shell 1 can effectively protect a device from damage caused by friction, wear, collision and falling during use. A shell notch 111 is provided at a shell corner 11 of the hard shell 1. The shell notch 111 is filled with a soft rubber block 211, thereby improving the elasticity of the protective shell during installation and making it more convenient to install or disassemble the device.

[0035] In the present invention, the soft inner frame 2 has elasticity, which can facilitate the installation or removal of the device, and at the same time improve the impact resistance of the protective shell to the device, which can effectively protect the device and prevent damage to the device. When the device is installed in the protective shell, because the soft inner frame 2 has a certain tolerance and error-tolerant size effect, a slight deviation in the size will not cause the device to loosen, so that the device is better fixed in the protective shell, giving the user a better use experience.
