[0029] Example 1

[0030] like Figure 1-5 As shown, this embodiment of the utility model provides a protective shell for an earphone case. The protective shell includes a shell body 1, a shell cap 2, and a flexible connector 3 connecting the shell body 1 and the shell cap 2. The flexible connector 3 includes an annular portion 31, which is connected to both the shell body 1 and the shell cap 2. The thickness W1 of the annular portion 31 in the radial direction is 0.4mm-1.0mm to prevent the annular portion 31 from breaking.

[0031] In this embodiment, the headphone case protective shell includes a shell body 1, a shell cap 2, and a flexible connector 3 connecting the shell body 1 and the shell cap 2. The flexible connector 3 can be made of elastic materials such as silicone or TPU. In this embodiment, the flexible connector 3 is connected to both the shell body 1 and the shell cap 2 through the annular portion 31. The bent part of the annular portion 31 is slender but needs a certain thickness for support, so that it can be bent multiple times without breaking easily. It also has a good concealment effect, minimizing the exposed area. The headphone case protective shell of this embodiment has a simple structure, has little impact on appearance, and is inexpensive, reducing manufacturing costs and improving aesthetics.

[0032] In this embodiment, the flexible connector 3 connecting the shell body 1 and the shell cap 2 can be connected by means of molding, gluing, welding, assembly, etc.; it can also be connected by other integral molding methods, curing molding methods, or detachable and replaceable methods.

[0033] In some embodiments, the flexible connector 3 includes a first connecting portion 32 constructed on the outer periphery of the annular portion 31, the inner wall of the shell body 1 is constructed with a first inset position 11, the first connecting portion 32 is disposed at the first inset position 11, and the side of the first connecting portion 32 facing the inner wall of the shell body 1 is flush with the inner wall of the shell body 1.

[0034] The first connecting part 32 and the first embedded part 11 can be fixed by welding / adhesion / mechanical connection.

[0035] In some embodiments, the length H1 of the first connecting portion 32 in the radial direction of the annular portion 31 is 6mm-15mm, ensuring that there is sufficient welding / bonding area between the first connecting portion 32 and the first inset 11, and ensuring the reliability of the connection between the first connecting portion 32 and the first inset 11.

[0036] In some embodiments, one or more first blind holes 111 are formed at the first embedded position 11, and one or more first insert parts 321 are formed on the side of the first connecting part 32 facing the first embedded position 11, which are inserted into the first blind holes 111 in a one-to-one correspondence, thereby further improving the reliability of the connection between the first connecting part 32 and the first embedded position 11.

[0037] In some embodiments, the flexible connector 3 further includes a pressing portion 33 constructed on the first connecting portion 32 away from the annular portion 31, and a through hole 12 is formed on the shell body 1 at a position opposite to the pressing portion 33, the pressing portion 33 extending into the through hole 12.

[0038] In related technologies, the headphone case has a button at this position. To accommodate the headphone case, the headphone case protective shell of this embodiment has a pressing part 33 at the position corresponding to the button, which can protect the original button. Moreover, the pressing part 33 and the first connecting part 32 can be integrally formed, which can save costs and avoid the problem that the pressing part 33 is easily lost when the pressing part 33 and the first connecting part 32 are designed separately.

[0039] In some embodiments, the flexible connector 3 further includes a second connecting portion 34 constructed on the outer periphery of the annular portion 31, wherein the first connecting portion 32 extends in the opposite direction to the second connecting portion 34, the inner wall of the cap 2 is constructed with a second inner insert 21, the second connecting portion 34 is disposed at the second inner insert 21, and the side of the second connecting portion 34 facing the inner wall of the cap 2 is flush with the inner wall of the cap 2.

[0040] The second connecting part 34 and the second inner part 21 can be fixed by welding / adhesion / mechanical connection.

[0041] In some embodiments, the length H2 of the second connecting portion 34 in the radial direction of the annular portion 31 is 6mm-15mm. This ensures that there is sufficient welding / bonding area between the second connecting portion 34 and the second insert 21, thereby ensuring the reliability of the connection between the second connecting portion 34 and the second insert 21.

[0042] In some embodiments, one or more second blind holes 211 are provided at the second embedded position 21, and one or more second insert portions 341, corresponding to each other, are provided on the side of the second connecting portion 34 facing the second embedded position 21. This further improves the reliability of the connection between the second connecting portion 34 and the second embedded position 21.

[0043] In some embodiments, the thickness W2 of the annular portion 31 in the axial direction is 0.9 mm to 1.3 mm to prevent the annular portion 31 from breaking.

[0044] Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific working processes of the devices, apparatuses, and units described above can be referred to the corresponding processes in the foregoing method embodiments, and will not be repeated here.

[0045] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
