Referring to fig. 1 to 4, the earphone charging box of the present embodiment includes an upper case 200 and a lower case 100, wherein an earphone accommodating cavity 110 for accommodating an earphone 300 is formed on the lower case 100, and when the earphone 300 needs to be charged or stored, the earphone 300 is placed in the earphone accommodating cavity 110 so as to be stored or charged by the earphone charging box; the upper case 200 serves to open or close the lower case 100. In this embodiment, the upper case 200 may move up and down under an external force with respect to the lower case 100, close the lower case 100 when it moves down with respect to the lower case 100 to be aligned with the lower case 100, open the lower case 100 when the upper case 200 moves up to be separated from the lower case 100 to a side away from the lower case 100, and allow a user to conveniently take out the earphone 300 when the upper case 200 moves up to a position where the user can take out the earphone 300; as shown in fig. 4, the earphone charging box of the present embodiment further includes a guide hole 400 and a guide shaft 500; the guide hole 400 is formed in the lower case 100 and extends in a vertical direction, the guide shaft 500 is located below the upper case 200 and also extends in a vertical direction, the top end of the guide shaft 500 is fixedly connected to the upper case 200, and the bottom end of the guide shaft is inserted into the guide hole 400, which can be driven by the upper case 200 to move up and down along the guide hole 400.

When the charging box needs to be opened, referring to fig. 5, an upward pulling force is applied to the upper case 200 (the pulling force direction is shown by an arrow in fig. 5 which is vertically upward), and when the upper case 200 is pulled to rise to facilitate taking and placing of the earphone 300, the earphone 300 can be taken out or placed; when closed, the upper case 200 is pushed downward to be coupled with the lower case 100 to close the lower case 100.

Further, as shown in fig. 2, 4 to 7, the charging box for the earphone of the present embodiment further includes a first stopper 600 and a second stopper 700, the first stopper 600 is fixed to the top end of the guide hole 400, and a through hole 610 through which the guide shaft 500 passes is formed in the first stopper 600; the second stop block 700 is fixedly arranged at the bottom end of the guide shaft 500 through a screw I, and is located below the first stop block 600. Through setting up first stopper 600 and second stopper 700, can prevent effectively that guiding axle 500 from breaking away from guiding hole 400 by the top of guiding hole 400, further guarantee the use reliability of charging box.

In addition, as shown in fig. 2 and fig. 4 to fig. 7, the earphone charging box of the present embodiment further includes a third stop block 800 and an elastic member 900, the elastic member 900 is used for applying a downward pushing force to the second stop block 700 to drive the upper case 200 to close the lower case 100, and the elastic member 900 is located between the first stop block 600 and the second stop block 700 in a compressed state; the third stopper 800 is fixed to the bottom end of the guide hole 400 and stops the second stopper 700 from being separated from the guide hole 400.

As shown in fig. 4, the elastic member 900 is in a compressed state, and pushes the second stopper 700 downward, thereby indirectly applying a downward pulling force to the upper case 200, so that the upper case 200 keeps closing the lower case 100; when the upper case 200 is pulled upwards by a pulling force indicated by an upward vertical arrow in fig. 5 to conveniently take and place the earphone 300, since the elastic member 900 is always in a compressed state and the second stopper 700 always has a pulling force on the upper case 200, after the earphone is taken out or placed, the user releases his hand, and the upper case 200 is reset to a state of closing the lower case 100 by the pulling force of the elastic member 900, so that the upper case 200 automatically closes the lower case 100 without manual operation, as shown in fig. 4.

In order to make the upper case 200 be able to keep at the position when the upper case 200 is lifted to the position where the user can conveniently take and place the earphone 300, i.e. to release the hand of the user which originally applies pulling force to the upper case 200, so as to further facilitate the user to conveniently take and place the earphone by one person; to achieve the technical effect, as shown in fig. 4 to 7, the first stopper 600 and the guide shaft 500 are provided with stopping structures which cooperate with each other to keep the upper case 200 in a state of opening the lower case 100, and when the upper case 200 is lifted to open the lower case 100 and kept in this state by the stopping structures, as shown in fig. 5 to 7, a bottom position a of the upper case 200 is higher than a top position b of the earphone 300, so as to facilitate taking and placing of the earphone.

In this embodiment, the stopping structure includes a fourth stopping block 510 formed on the guide shaft 500 and a stopping hole 620 formed on the first stopping block 600, the fourth stopping block 510 is long, the shape of the stopping hole 620 is matched with that of the fourth stopping block 510, the stopping hole 620 is located above the through hole 610, the top end of the stopping hole 620 penetrates through the first stopping block 600, the bottom end of the stopping hole 620 is communicated with the through hole 610, and the guide shaft 500 sequentially penetrates through the stopping hole 620 and the through hole 610 and extends into the lower part of the first stopping block 600; the fourth stopper 510 can move up and down along the stopper hole 620 with the guide shaft 500 under an external force, and when the fourth stopper rises to be separated from the stopper hole 620, the guide shaft 500 can circumferentially rotate relative to the through hole 610 and the second stopper 700 can circumferentially rotate relative to the guide hole 400 under the external force. When the upper case 200 is pulled upward and the guide shaft 500 drives the fourth stopper 510 to rise along the stopper hole 620 to be separated from the stopper hole 620, since the guide shaft 500 and the second stopper 700 can rotate circumferentially, the upper case 200 is rotated at this time to rotate the guide shaft 500 and the second stopper 700 circumferentially and further drive the fourth stopper 510 to rotate circumferentially, and since the stopper hole 620 is matched with the fourth stopper 510 in shape, i.e., a long hole, the fourth stopper 510 can rotate to be staggered with the stopper hole 620, so that when a user releases a hand originally applying a pulling force and a rotating force to the upper case 200, the fourth stopper 510 stops on the top surface of the first stopper 600 under the pulling force of the elastic member 900, as shown in fig. 8, the guide shaft 500 can be prevented from driving the upper case 200 to be reset, and the upper case 200 can be maintained in a state of opening the lower case 100. As shown in fig. 6 and 7, the upper case 200 is rotated by 90 °, on one hand, the stop of the upper case 200 when the lower case 100 is opened is achieved, and on the other hand, since the earphones 300 are generally arranged left and right along the length direction of the lower case 100 as shown in fig. 4 to 7, and the length direction of the lower case 100 corresponds to the length direction of the upper case 100, after the upper case 200 is rotated by a certain angle, the length direction of the earphones can be kept away from the earphones 300, as shown in fig. 6, so as to prevent the earphones 300 from interfering with the upper case 200 in the taking and placing process, and further facilitate the taking and placing of the earphones 300.

Further, the upper case 200 and the lower case 100 are coaxial, the guide shaft 500 is coaxial with the upper case 200, and the guide hole 400 is coaxial with the lower case 100, so that the lifting and opening and closing actions of the upper case 200 are smooth.

Furthermore, since the earphone 300 in this embodiment is a dual wireless earphone, which includes two earphone units, the earphone accommodating cavity 110 in this embodiment is formed by two

independent cavities

110A and 110B disposed left and right, and the two independent cavities are symmetrically disposed with respect to the axis of the lower case 100, so that the two earphone units are respectively taken and placed from the left and right sides, and the two

independent cavities

110A and 110B are both similar to the earphone unit of the earphone 300 in shape, so as to improve the placement stability of the earphone units. And the earphone accommodating cavity 110 is inclined outwards relative to the axis of the lower shell 100, i.e. the cavity mouth end is located at the outer side than the cavity bottom end, so as to further facilitate the taking and placing of the earphone.

As shown in fig. 4, the receiving groove 120 is formed above the guide hole 400, the inner diameter of the receiving groove 120 is larger than the inner diameter of the guide hole 400, a through hole communicated with the guide hole 400 is formed at the bottom of the receiving groove 120, the first stop block 600 is a T-shaped block, the vertical portion of the first stop block 600 is inserted into the guide hole 400, and the horizontal portion is fixed to the bottom of the receiving groove 120 by a screw II. Specifically, the receiving groove 120 is deeper than the thickness of the horizontal portion of the first stop block 600, so as to prevent the first stop block 600 from being exposed to interfere with the matching of the upper case 200 and the lower case 100.

For the third stopper 800, in this embodiment, it is a rubber plug, but it may also be a plastic block, so a rubber plug is preferable because the rubber plug has elasticity, on one hand, it can provide a buffer for the second stopper 700 when retracting along with the elastic component 900, on the other hand, it can reduce the noise when the second stopper 700 collides with it; specifically, the periphery of the third stopper 800 is fixedly connected to the bottom end of the guiding hole 400. Meanwhile, the third stopper 800 is inserted into the guide hole 400, or the bottom surface of the third stopper 800 is flush with the bottom surface of the lower case 100, as shown in fig. 4 to 7, so as not to affect the placement of the charging cartridge.

Example two

Unlike the first embodiment, the stopper structure of the present embodiment includes a first protrusion 630 formed on an inner wall of the through hole 610 of the first stopper 600 and a second protrusion 520 formed on an outer wall of the guide shaft 500, and at least one of the first protrusion 630 and the second protrusion 520 is an elastic protrusion. When the guide shaft 500 is raised, the second projection 520 is upwardly moved over the first projection 630 by the press-deformation of the second projection 520 and the first projection 630 on the inner wall of the through hole 610 to stop the first projection 630 to position the guide shaft 500, thereby maintaining the upper case 200 in a state of opening the lower case.

The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions.
