For ordinary skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.
[0029] In an embodiment of the present application, as shown in Figure 1 A shell swing mechanism is provided, which comprises an ear shell body 10, a sliding arm 20, a rotating shaft 30, a rotating shaft support 40 and a spring, a through hole 11 is formed in the side of the ear shell body 10, the end of the sliding arm 20 passes through the through hole 11 into the ear shell body 10, the rotating shaft 30 is sleeved on the end of the sliding arm 20 located in the ear shell body 10, the rotating shaft support 40 is fixed in the inside of the ear shell body 10, the side of the rotating shaft 30 is rotatably connected with the rotating shaft support 40, the spring is connected between the inside of the ear shell body 10 and the rotating shaft 30, further, the spring is a compression spring 50, the middle part of the compression spring 50 abuts against the top of the rotating shaft 30, and both ends of the compression spring 50 are positioned and connected in the inside of the ear shell body 10.
[0030] The shell swing mechanism provided by the embodiments of the present application can be applied to a headset, when used, the sliding arm 20 is swung relative to the ear shell body 10 by the rotation of the rotating shaft 30 relative to the rotating shaft support 40, because the through hole 11 is arranged on the shell body, the sliding arm 20 can swing in the space of the through hole 11, and then the swing of the ear shell body 10 relative to the sliding arm 20 can be realized, when the sliding arm 20 swings, the pressure of the compression spring 50 applied to the rotating shaft 30 is overcome, after the pressure is removed, the relative position of the ear shell body 10 and the sliding arm 20 returns to the original state, so that the damping effect is realized, the whole design does not have exposed structure, that is, there is no exposed ear fork design, which is more simple and has smaller overall thickness.
[0031] In another embodiment of the present application, as shown in Figure 1As shown, the upper end of the rotating shaft 30 is provided with an extension hook 31, and the compression spring 50 is in the shape of Ω, and the middle part of the compression spring 50 in the shape of Ω is buckled in the extension hook 31. Specifically, the middle part of the compression spring 50 in the shape of Ω is formed with a groove structure, which can be buckled in the extension hook 31 at the upper end of the rotating shaft 30, and is stable and reliable. The other two ends of the compression spring 50 in the shape of Ω are free ends, which are fixedly connected to the inside of the ear shell body 10. Thus, the position of the rotating shaft 30 can be limited by the entire compression spring 50 in the shape of Ω, thereby limiting the position of the sliding arm 20, and finally realizing that the ear shell body 10 can return to or tend to return to the original state after the swinging angle and the removal of external force. The structure design is ingenious and has high practicability.
[0032] In another embodiment of the present application, as shown in Figure 1 The inside of the ear shell body 10 is integrally formed with a mounting seat 12 located on both sides of the rotating shaft 30, and the mounting seat 12 on both sides is provided with an embedding groove 121, and the two ends of the compression spring 50 are embedded in the embedding groove 121. Specifically, the mounting seat 12 is integrally formed in the inside of the ear shell body 10, and then the embedding groove 121 can be easily designed on the mounting seat 12. The other two ends of the compression spring 50 in the shape of Ω are designed in a horizontal shape, which can be embedded in the embedding groove 121 of the mounting seat 12, so as to stably connect and fix the two free ends of the compression spring 50 in the shape of Ω in the inside of the ear shell body 10. Therefore, even if external force acts on the compression spring 50 in the shape of Ω, the compression spring 50 in the shape of Ω will not be easily disconnected.
[0033] In another embodiment of the present application, as shown in Figure 1 The rotating shaft bracket 40 is provided with two, and the two rotating shaft brackets 40 are locked on the two mounting seats 12 by fasteners.

For example, a convex shaft can be provided on both sides of the rotating shaft 30, and a shaft hole is provided on the rotating shaft bracket 40. The convex shaft is inserted into the shaft hole to realize rotation cooperation, so that the rotating shaft 30 can rotate relative to the two rotating shaft brackets 40, thereby realizing the relative rotation of the sliding arm 20 relative to the ear shell body 10.
[0034] In another embodiment of the present application, as shown in Figure 1As shown, at least one of the rotating shaft support 40 is provided with a limiting block 41, the rotating shaft 30 and the corresponding position of the limiting block 41 is provided with a limiting angle cavity 32 for the limiting block 41 to extend into and has a space, when the rotating shaft 30 rotates relative to the rotating shaft support 40, the cavity wall of the limiting angle cavity 32 can abut against the limiting block 41. Specifically, the limiting block 41 is provided to abut against the limiting angle cavity 32, for example, when the rotating shaft 30 rotates (i.e. swings) relative to the rotating support to a certain position, it is limited by each other, so that the rotating angle of the ear shell body 10 relative to the sliding arm 20 is too large, which can avoid damaging the ear shell body 10. Wherein, the limiting angle cavity 32 can be an open structure, which is formed by two stop blocks and the outer wall of the rotating shaft 30, or can be realized by setting a hole structure on the rotating shaft 30.
[0035] In another embodiment of the present application, as shown in Figure 2 The elastic member is a tension spring 60, the upper end of the rotating shaft 30 is provided with an extension hook 31, the upper end of the tension spring 60 is hooked in the extension hook 31, and the lower end of the tension spring 60 is positioned and connected in the inside of the ear shell body 10. The tension spring 60 can also be used to connect the rotating shaft 30 with the inside of the ear shell body 10, so that the ear shell body 10 can be reset after swinging relative to the ear shell body 10 and removing the force.
[0036] Further, as shown in Figure 2 The lower end of the tension spring 60 is hooked on the connecting seat 13 arranged in the inside of the ear shell body 10. The connecting seat 13 is also integrally injection molded in the inside of the ear shell body 10, which is specially used for connecting the lower end of the tension spring 60.
[0037] In another embodiment of the present application, as shown in Figure 3 The elastic member is a compression spring 50 and a tension spring 60, the middle part of the compression spring 50 abuts against the top of the rotating shaft 30, both ends of the compression spring 50 are positioned and connected in the inside of the ear shell body 10, the upper end of the tension spring 60 is hooked in the extension hook 31, and the lower end of the tension spring 60 is positioned and connected in the inside of the ear shell body 10.
