[0035] The mobile device case 1 may further include first and / or second connecting parts 30, 40.

[0036] As shown in Figure 8, the first connecting portion 30 may include first and second insertion plugs 31, 32 which are connected to the first body portion 10 and the second body portion 20, respectively, and a first connecting plug 33 which connects the first and second insertion plugs 31, 32. The first connecting portion 30 is formed of an elastic material, more specifically, a synthetic resin material. The first and second insertion plugs 31, 32 and the connecting plug 33 may be deformed in shape and / or form by external forces. The first and second insertion plugs 31, 32 and / or the connecting plug 33 may be formed of a variety of elastic materials such as rubber, silicone, spring steel, polyurethane, neoprene, latex, and ethylene propylene diene monomer (EPDM).

[0037] The connecting plug 33 is formed in the shape of a "U" as shown in Figure 9, with the first and second insertion plugs 31 and 32 attached to both ends. The connecting plug 33 may have a shape and / or form that is thinner in the central part. The connecting plug 33 may be formed to be flattened in the first side corresponding to where the first and second insertion plugs 31 and 32 are positioned, and to be concave in the second side corresponding to the second side opposite the first side. The connecting plug 33 may be formed to be slightly thicker in the part other than A and bend at A. The connecting plug 33 may have a dumbbell shape that is thinner in the middle, but is not limited to this and can have a variety of shapes. The connecting plug 33 can be bent at a predetermined angle along the second side as shown in Figure 7 (A', see Figure 7).

[0038] As shown in Figure 10, the connecting portion 30 may have grooves 34 and 35 on the sides opposite to the surfaces from which the first and second insertion plugs 31 and 32 protrude. The grooves 34 and 35 may have the same shape as the planar shapes of the first and second insertion plugs 31 and 32. As shown in Figure 11, the first insertion plug 31 of the connecting portion 30 may have a flanged head shape and a tapering neck shape 31-1 so that it can be inserted into the first side hole.

[0039] The second connecting portion 40 can be formed with the same structure as the first connecting portion 30 in Figure 8.

[0040] As shown in Figure 2, a first side hole 16 is located at the end of one side of the first fuselage section 10, and a second side hole 22 is located at the end of one side of the second fuselage section 20. The first insertion plug 31 of the first connecting section 30 connects with the first side hole 16, and the second insertion plug 32 of the first connecting section 30 connects with the second side hole 22, so that the first fuselage section 10 and the second fuselage section 20 can be connected through the first connecting section 30. The first fuselage section 10 and the second fuselage section 20 can form an integrated structure centered on the first connecting section 30. Here, engagement can be carried out by methods such as press-fitting, screw engagement, or elastic engagement.

[0041] One of the first connecting portion 30 and the second connecting portion 40 can be attached to the left or right side of the mobile device case.

[0042] The first connecting portion 30 and / or the second connecting portion 40 can be connected to the first body portion 10 and the second body portion 20 before the mobile device is inserted into the first body portion 10 or the second body portion 20. The first connecting portion 30 and / or the second connecting portion 40 can be connected to the corresponding side holes 16, 17, 22, and 23 inside the first body portion 10 and the second body portion 20. The mobile device can be inserted after the first body portion 10, the second body portion 20 and the first connecting portion 30 are connected (see Figure 8). Upon insertion of the mobile device, the connection state of the first insertion plug 31 and the second insertion plug 32 of the first connecting portion 30 with the side holes 16 and 22 can be concealed. Through this, it is possible to prevent the first insertion plug 31 and the second insertion plug 32 from being separated by external shocks, external forces, etc., after the mobile device has been inserted, and the first connecting portion 30 can mitigate the impact caused by the mobile device falling. The connection is made internally, allowing for a smooth, integrated appearance. The connecting plug 33 of the first connecting section 30 may be exposed externally and protrude. The connecting plug 33 can enable the first body section 10 and the second body section 20 to rotate or fold. The connecting plug 33 can function as a pivot axis that allows the first and second body sections to rotate. The connecting plug 33 can be designed as a hinge or pivot structure. The connecting plug 33 can be exposed externally to allow the first body section 10 and the second body section 20 to rotate. The connecting plug 33 can allow the first body section 10 and the second body section 20 to be folded by a foldable mobile device. The thickness of the sides of the first body section 10 and the second body section 20 where the side holes 16, 17, 22, and 23 are located can be adjusted to correspond to the height of the insertion plugs 31 and 32. The inner surfaces of the first or second connecting portions 30, 40 may be formed to be flat so that a mobile device can be inserted when the first or second connecting portions 30, 40 are joined. The first or second connecting portions 30, 40 may be formed to have flat surfaces so that they can contact the sides of the mobile device when joined.

[0043] The first and second insertion plugs 31 and 32 may be formed to remain fixed without rotating after being coupled to the first side hole 16 and the second side hole 22. The first and second insertion plugs 31 and 32 can be fixed without rotating after engaging with the first side hole 16 and the second side hole 22. The first and second insertion plugs 31 and 32 may have shapes other than circular to prevent unnecessary rotation when coupled to the side holes. The first and second insertion plugs 31 and 32 may preferably be elliptical or D-shaped in plan, but are not limited thereto, and may have shapes such as rectangles or squares.

[0044] The first side hole 16 and the second side hole 22 are located in the first body section 10 and the second body section 20, respectively, and may be formed to be located within a predetermined distance of each other when a mobile device case is attached.

[0045] The first side hole and the first insertion plug can be detached and attached. Each side hole and insertion plug can be connected and separated for the convenience of the user.

[0046] Additional third side holes 17 and fourth side holes 23 are provided in the first fuselage section 10 and the second fuselage section 20, and the insertion plug of the second connecting section 40 can be connected to the third and fourth side holes 17 and 23, respectively.

[0047] As shown in Figure 7, after being joined, the first and second fuselage sections 10 and 20 will rotate along an axis between them. The connecting plug 33 may form the axis of rotation. The axis of rotation can be located in the space between the first fuselage section 10 and the second fuselage section 20.

[0048] In an embodiment of the present invention, the insertion plugs can be connected to the respective side holes before inserting the mobile device into the mobile device case 1.

[0049] As shown in Figure 9, the first connecting portion 30 may include a connecting plug 33 that connects the first insertion plug 31 and the second insertion plug 32. The connecting plug 33 may include a bendable portion A that allows bending and a fixed portion. The fixed portion can be fixed without bending as the first insertion plug 31 and the second insertion plug 32 are attached and fastened to the mobile device.

[0050] The bent portion A can be designed to have a relatively thin thickness R2. The thickness R2 of A can be 70-80% of the thickness R1 of the fixed portion. Preferably, R2 can be 1mm-2mm. The thinner the thickness R2 of the bent portion A, the more easily it can be bent, and the greater the risk of breakage. R2 can be optimized for the effect of bending within a target bending angle range. The target bending angle range may be determined considering the rotation range of the mobile device. A folder-type mobile device can have a rotation range from 0 to 180 degrees. When the mobile device is fully unfolded, the connecting plug 33 is fully extended. When the mobile device is fully folded, the bent portion A of the connecting plug 33 can be fully folded.

[0051] The length L2 of the bent portion A may be 20-30% of the total length L1 of the first connecting portion 30. Preferably, the total length L1 of the first connecting portion 30 may be 13 mm to 20 mm. If the length L2 of the bent portion A is longer than a predetermined standard maximum value, the risk of buckling may increase when axial load / torsional load is applied. If the length L2 of the bent portion A is longer than a predetermined standard minimum value, it may be difficult to meet the target bending angle range.

[0052] Although preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the specific embodiments described above, and it is of course possible for a person with ordinary skill in the art to which the invention belongs to make various modifications without departing from the gist of the present invention as claimed in the claims, and such modifications are not individually understood from the technical idea or prospects of the present invention.
