Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 and 4, fig. 1 is a perspective view of an overall structure of an embodiment of the present invention, as shown in fig. 4, fig. 4 is a schematic flow chart illustrating a user taking an earphone body a from an earphone storage box.

The utility model provides an among the specific implementation mode, the earphone receiver mainly includes casing 1 down, holds box 2 and rotatory lid 3.

As shown in fig. 2, fig. 2 is an exploded schematic view of fig. 1.

Wherein, lower casing 1 is major structure, has seted up the cavity in it, holds box 2 and sets up in lower casing 1, mainly used installation earphone body a.

The rotary cover 3 is rotatably disposed in the lower case 1, and in a rotational stroke of the rotary cover 3, the opening of the lower case 1 may be closed when rotated to a certain orientation, or the opening of the lower case 1 may be fully opened when rotated to a certain orientation, that is, switching of the opening of the lower case 1 between the closed and open states is achieved by a rotational movement of the rotary cover 3.

So, the earphone receiver that this embodiment provided, through the rotary motion of rotatory lid 3 in casing 1 down, can conveniently realize the operation that opens and shuts to the earphone receiver, compare in prior art, need not additionally to add structures such as hinge to can reduce the volume and occupy, reduction in production cost.

In order to facilitate the rotation of the rotary cover 3 in the lower housing 1, a certain space, i.e. a rotary cavity b, is left between the inner wall of the lower housing 1 and the outer wall of the accommodating box 2 in this embodiment, and the rotary cavity b is mainly used for the rotary cover 3 to rotate so as to provide the space required by the rotation. In general, the shape of the rotary chamber b may be arc-shaped as a whole, considering that the rotary cover 3 performs a rotary motion. It is important that when the rotary cover 3 is rotated to the maximum angle, it can be completely accommodated in the rotary cavity b, that is, the rotary cover 3 can completely open the opening of the lower case 1, and completely expose the earphone body a mounted on the inner accommodating box 2, which is convenient for the user to take. Of course, when the rotary cover body 3 rotates reversely to the maximum angle, the opening of the lower shell 1 can be completely closed naturally, the earphone body a is ensured to be stably installed in the accommodating box 2, and the earphone body a is prevented from being accidentally separated from the lower shell 1.

In order to adapt to the rotation of the rotary cover 3, in this embodiment, the lower housing 1 may be an incomplete circular frame, and the rotary cover 3 may be an arc frame, so that when the rotary cover 3 rotates to completely close the opening of the lower housing 1, the lower housing 1 and the rotary cover 3 are combined to form a disc-shaped structure. Accordingly, since the accommodation box 2 is installed in the lower case 1, the specific shape of the accommodation box 2 may be similar to that of the lower case 1, being an incomplete circular disk, for the convenience of installation.

Further, in order to facilitate smooth taking out of the earphone body a when the rotary cover body 3 is rotated to be opened, in the present embodiment, the surface of the accommodation case 2 may be flush with the opening surface of the lower case 1. Of course, it is also possible if the surface of the accommodation box 2 is slightly higher or lower than the opening surface of the lower case 1.

In a preferred embodiment of the rotating cover 3, in order to ensure stable and smooth rotation, the rotating cover 3 is rotatably sleeved on the accommodating box 2 in this embodiment. With this arrangement, since the housing case 2 is fixedly mounted in the lower case 1, the rotary lid body 3 can be rotated in the lower case 1 with the housing case 2 as a rotation fulcrum.

Specifically, in the present embodiment, the rotation holes 31 are respectively formed on both side edges of the rotation cover 3, the rotation shafts 21 are respectively disposed on both side edges of the accommodation box 2, the rotation holes 31 are sleeved on the corresponding rotation shafts 21, and a clearance shaft hole is formed between the rotation holes 31 and the rotation shafts 21 for circumferential rotation of the rotation holes 31 on the rotation shafts 21. With this arrangement, the rotary cover 3 can be rotated on the accommodation box 2 by engaging the rotary hole 31 with the rotary shaft 21. Here, preferably, in view of structural standardization while facilitating manufacturing, in the present embodiment, the rotation hole 31 may be particularly opened at a position of a center of curvature of the rotation cover body 3, and similarly, the rotation shaft 21 may be particularly opened at a position of a center of curvature of the accommodation box 2. Also, since the rotation hole 31 is fitted over the rotation shaft 21, the rotation cover 3 and the accommodation box 2 form a concentric structure. In addition, considering that the storage box 2 is generally disposed at the center of the lower case 1, the rotary cover 3, the storage box 2, and the lower case 1 are all concentrically arranged.

Further, in order to reduce the rotation resistance of the rotating cover 3 in the lower housing 1, a plurality of mounting holes 32 are formed on both sides of the rotating cover 3, and the balls 4 are mounted in the mounting holes 32. Meanwhile, a plurality of rolling grooves 22 are formed on both side edges of the container 2 along a certain curvature radius. The number of the rolling grooves 22 is the same as the number of the mounting holes 32, and the distance from each mounting hole 32 to the rotation hole 31 is equivalent to the curvature radius of each corresponding rolling groove 22. With this arrangement, when the rotary cover 3 rotates in the lower case 1, each mounting hole 32 rotates synchronously with the rotary cover, and then each ball 4 therein is driven to roll synchronously, and each mounting hole 32 corresponds to each rolling groove 22, so each ball 4 can roll in each corresponding rolling groove 22 along the circumferential direction, and the rolling friction of the balls 4 reduces the rotation resistance of the rotary cover 3 in the lower case 1, and the rotary motion of the rotary cover 3 is smoother.

Similarly, the rotating shaft 21 and the rolling groove 22 can be arranged on the inner walls of the two sides of the lower shell 1, which is equivalent to extending the length of the rotating shaft 21 on the accommodating box 2 by using the rotating shaft 21 on the lower shell 1, thereby preventing the rotating hole 31 from accidentally separating from the rotating shaft 21 during rotation; meanwhile, the arrangement position of the rolling groove 22 formed on the lower shell 1 corresponds to the arrangement position of the rolling groove 22 formed on the accommodating box 2, which is equivalent to mutually buckling to form a rolling space, so that the rolling movement of the ball 4 in the rolling space is more convenient.

As shown in fig. 3, fig. 3 is a schematic structural view illustrating the rotating cover 3 respectively rotated to the unfolded and storage states.

In addition, in order to facilitate the user to pull the rotary cover 3 to rotate it, the present embodiment provides the limit handle 5 on the circumferential outer wall of the rotary cover 3, so that the user can grasp the limit handle 5 to perform a force operation. Specifically, the limit knob 5 is provided at an edge position of the circumferential outer wall of the rotary cover body 3, and the bottom thereof is smooth, so that when the rotary cover body 3 is rotated out of the rotary cavity b by a maximum angle, the outer end of the rotary cover body 3 can be stably pressed against the opening surface of the lower case 1 by abutment between the bottom of the limit knob 5 and the opening surface of the lower case 1, and the opening of the lower case 1 is kept in a closed state.

Furthermore, when the rotary cover 3 is rotated to the rotary chamber b for storage, there is a maximum rotation angle. Specifically, the present embodiment is provided with the abutting block 6 on the circumferential outer wall of the accommodating box 2, and the abutting block 6 may be in a fan-shaped structure, and is mainly used for limiting the maximum radian of the rotating cavity b. When the rotary cover 3 is rotatably accommodated in the rotary cavity b, the inner end of the rotary cover 3 abuts against the surface of the abutment block 6 at the end position of the rotary cavity b, and at this time, the rotary cover 3 is at the maximum rotary accommodating angle, and the opening of the lower housing 1 is in a fully opened state.
