The invention provides an earphone box which is used for containing wireless earphones.

In an embodiment of the present invention, please refer to fig. 1 to fig. 6 in combination, the earphone box includes a box body 10 and a box cover 20. The earphone box can be round, oval or square. In addition, a rechargeable battery can be arranged in the earphone box to charge the wireless earphone placed in the earphone box. Of course, the secondary battery may not be provided.

In this embodiment, the earphone box further includes an elastic expansion member 30, and the box cover 20 is rotatably connected to the box body 10 to have an open state (refer to fig. 2 and 3) in which the box body 10 is opened and a closed state (refer to fig. 4 and 5) in which the box body 10 is closed. One end of the elastic expansion piece 30 is rotatably connected with the box body 10, and the other end is movably connected with the box cover 20, when the box cover 20 is switched between an open state and a closed state, the elastic expansion piece 30 can move relative to the box cover 20, so that the elastic expansion piece 30 is compressed, and in the open state, the elastic expansion piece 30 is in a compressed state, so that the box cover 20 has a tendency of being kept open.

In this embodiment, the box 10 has a receiving cavity 13, the elastic expansion piece 30 is disposed in the receiving cavity 13, the box 10 has a connecting portion 121, one end of the elastic expansion piece 30 is rotatably connected to the connecting portion 121, and one end of the elastic expansion piece 30 away from the connecting portion 121 is movably connected to the box 10. The expansion direction of the elastic expansion member 30 is the arrangement direction of both ends thereof. For convenience of description, a rotation axis of the cover 20 to be rotated open with respect to the case 10 will be defined as a first axis. When the elastic expansion member 30 is in a free state (i.e., a state in which the elastic expansion member 30 is neither compressed nor stretched), the extension direction of the elastic expansion member 30 is substantially perpendicular to the extension direction of the first axis. The elastic expansion element 30 can rotate at least in a plane perpendicular to the first axis, that is, a rotation axis of the elastic expansion element 30 rotatably connected to the case 10 (hereinafter, a rotation axis of the elastic expansion element 30 rotatably connected to the case 10 is defined as a second axis) is parallel to the first axis. In other words, the elastic expansion member 30 can be rotatably coupled to the case 10 only in one direction, and the elastic expansion member 30 is rotated to form a rotation plane perpendicular to the second axis, which is perpendicular to the first axis. Or the elastic expansion piece 30 can be rotatably connected with the box body 10 along any direction, that is, the elastic expansion piece 30 has a rotation center, the elastic expansion piece 30 can rotate along a plurality of directions to form a plurality of rotation planes, and one rotation plane in the plurality of rotation planes is perpendicular to the first axis. It can be understood that, when the cap 20 is in the open state, the cap 20 can abut against the case 10, thereby limiting the excessive rotation of the cap 20.

It should be noted that the first axis and the second axis are fixed in position on the case body 10, and the cover 20 has a connection structure connected to the elastic expansion member 30, and the connection structure can rotate about the first axis when the cover 20 is switched between the open state and the closed state. The relative position of the connection structure and the second axis changes as the cap 20 rotates, for example, the distance between the connection structure and the second axis decreases or increases as the cap 20 rotates. Therefore, when the end of the elastic expansion piece 30 far away from the connecting part 121 is movably connected with the box cover 20, the compression state of the elastic expansion piece 30 can be changed, and the elastic expansion piece 30 can be in the compression state in the uncovering state. Because the end of the elastic expansion piece 30 far away from the connecting part 121 is movably connected with the box cover 20, the occurrence of the situation of the dead locking among the elastic expansion piece 30, the box cover 20 and the box body 10 can be avoided.

In the opened state (refer to fig. 3 and 4 in combination), the elastic expansion piece 30 has an abutting acting force F0 on the box cover 20, the direction of the abutting acting force is the same as the extending direction of the elastic expansion piece 30, the abutting acting force F0 can be divided into a first component force F1 and a second component force F2, the first component force F1 points to the first axis, the direction of the second component force F2 is parallel to the tangential direction of the rotating direction (the direction X in fig. 4) of the box cover 20 when the box cover 20 is opened, that is, the elastic expansion piece 30 makes the box cover 20 have the tendency of moving along the opening direction through the second component force F2, and further makes the box cover 20 have the tendency of keeping open. When the lid needs to be closed in the open state, a force overcoming the second component F2 needs to be applied to the lid 20 to rotate the lid 20 in the opposite direction until the elastic expansion piece 30 no longer applies a force in the opening direction to the lid 20, so that the lid 20 can be switched from the open state to the closed state. The direction of the force applied to the box cover 20 by the elastic expansion piece 30 can be changed by rotating the box cover 20, or the elastic expansion piece 30 can be restored to a free state, so that the elastic expansion piece 30 does not apply an acting force to the box cover 20 in the opening direction.

According to the technical scheme, the elastic expansion piece 30 is arranged between the box body 10 and the box cover 20 of the earphone box, one end of the elastic expansion piece 30 is rotatably connected with the box body 10, and the other end of the elastic expansion piece 30 is movably connected with the box cover 20, so that when the box cover 20 is opened and is in an open state, the elastic expansion piece 30 can move relative to the box cover 20 and the box body 10 and is compressed to be in a compressed state, the elastic expansion piece 30 has an acting force abutting against the box cover 20 to be opened continuously, and the box body 10 can limit the box cover 20 to rotate continuously along the opening direction, so that the elastic expansion piece 30 can abut against the box cover 20 and is in a trend of keeping the box cover open. At this moment, if the cover 20 is to be switched to the cover closing state from the cover opening state, external force needs to be applied to overcome the action force of the elastic expansion piece 30 abutting against the cover 20 moving towards the opening direction, so that the situation that the cover 20 rotates automatically when the cover is in the cover opening state and covers the box body 10 is reduced, and great convenience is brought to a user to take out and put in an earphone box. Compare in the mode that keeps lid 20 to be in the open mode through axis of rotation respectively with box body 10, lid 20 interference fit, can avoid box body 10 and lid 20 to lead to the condition of fracture with pivot interference fit for a long time, also reduced the wearing and tearing between box body 10 and the lid 20, be favorable to prolonging the life of earphone box.

In one embodiment, the box body 10 includes a box body 11 and a mounting portion 12 disposed on the box body 11, the box body 11 is formed with a receiving cavity 13, the mounting portion 12 covers an opening of the receiving cavity 13, and the mounting portion 12 has an earphone slot; the box cover 20 is rotatably connected with the box body 11; the elastic expansion piece 30 is positioned in the containing cavity 13 and connected with the mounting part 12. Specifically, the earphone slot is located on the side of the mounting portion 12 away from the accommodating cavity 13, and the case cover 20 can cover the earphone slot in a closed state. The elastic extensible member 30 is connected to one side of the mounting portion 12 facing the accommodating cavity 13, that is, the connecting portion 121 is disposed on one side of the mounting portion 12 facing the accommodating cavity 13, so as to ensure that the elastic extensible member 30 is located in the accommodating cavity 13, thereby better protecting the elastic extensible member 30 and preventing the elastic extensible member 30 from being easily damaged when exposed outside the box body 10.

For better explanation, the side of the box cover 20 is taken as the top and the side of the box 10 is taken as the bottom, but when the placement posture of the earphone box is changed, the directional indication between the box cover 20 and the box 10 is changed accordingly.

In one embodiment, the box 10 has an opening (not shown), the cover 20 covers the opening, the box 10 further has a first sidewall 111 and a second sidewall 112 opposite to the first sidewall, the second sidewall 112 is rotatably connected to the cover 20, the elastic expansion member 30 has a first connecting end rotatably connected to the box 10 and a second connecting end connected to the cover 20, the first connecting end is located between the second connecting end and the first sidewall 111, and the first connecting end is close to the opening opposite to the second connecting end.

Specifically, the opening is disposed upward, the first axis is close to the opening, and the first connection end is located between the first axis and the opening, that is, the first connection end is located above the first axis. The box body 11 has the opening facing upward, the mounting portion 12 is disposed at the opening, the connecting portion 121 is located above the first axis, and the first connecting end of the elastic expansion member 30 is rotatably connected to the connecting portion 121. So be equivalent to being close to the opening setting with elastic expansion piece 30, can improve the space utilization of box body 10 opening part to can improve the structure of earphone box compacter, be favorable to reducing the volume of earphone box, perhaps can increase the accommodation space in the earphone box, thereby when box body 10 sets up rechargeable battery, can increase rechargeable battery's capacity.

In this embodiment, in the uncapped state (refer to fig. 3 and 4), the second connection end is located between the first axis and the opening, that is, the second connection end is also located above the first axis, and a stress position between the second connection end and the box cover connection structure is also located above the first axis. At this time, the abutting force F0 of the elastic expansion piece 30 to the box cover 20 is directed from the first side wall 111 to the second side wall 112, and the abutting force F0 is shifted upward of the first axis, so that the abutting force F0 can be decomposed into a first component force F1 directed to the first axis and a second component force F2 parallel to the tangential direction of the rotating direction of the box cover 20 (the rotating direction when the box cover 20 is opened, for example, the X direction in fig. 4), so that the box cover 20 can have a tendency to move in the opening direction by the second component force F2, and the box cover 20 can have a tendency to remain open.

Of course, in other embodiments, the first connection end may be located on a side of the first axis away from the opening, that is, the first connection end is located below the first axis. Or the first connecting end and the first axis are arranged in parallel in the vertical direction. Further, the mounting portion 12 may be provided integrally with the cartridge body 11. Alternatively, the mounting portion 12 and the cartridge body 11 may be detachably connected, for example, the mounting portion 12 and the cartridge body 11 may be engaged or screwed together. Or the mounting portion 12 is bonded to the cartridge body 11. In addition, the connection portion 121 may be provided on the cartridge body 11.

Referring to fig. 5 to 10, in an embodiment, a connection shaft 23 is disposed on the box cover 20, and the elastic expansion element 30 is slidably connected to the connection shaft 23. Specifically, one end of the elastic expansion piece 30 is rotatably connected to the case 10, and the other end is slidably connected to the connecting shaft 23. The connecting shaft 23 extends in a direction perpendicular to the rotational axis of the case 10, i.e., the extending direction of the connecting shaft 23 is substantially perpendicular to the extending direction of the first axis. The box cover 20 is further provided with a limiting part. When the lid 20 is opened, the elastic expansion piece 30 abuts against the limiting portion, and the elastic expansion piece 30 is in a compressed state, so that the lid 20 tends to be opened. The limiting portion may be disposed on the connecting shaft 23, or may be disposed at a connection position of the connecting shaft 23 and the box body 10.

In one embodiment, the elastic expansion element 30 includes a first connecting element 31, an elastic element 33, a second connecting element 32 and a sliding block 34, the elastic element 33 is respectively connected with the first connecting element 31 and the second connecting element 32, the first connecting element 31 is rotatably connected with the box body 10, the second connecting element 32 is rotatably connected with the sliding block 34, and the sliding block 34 is slidably connected with the connecting shaft 23. Specifically, the first connection end is an end of the first connection member 31 away from the second connection member 32, the second connection end is an end of the second connection member 32 away from the first connection member 31, and the first connection member 31 and the second connection member 32 are both hard members and are used for fixedly connecting the elastic member 33. The second connection end is rotatably connected to the box cover 20, and the first connection member 31 is substantially parallel to the rotation axis of the box cover 20, the second connection member 32 is substantially parallel to the rotation axis of the slider 34, and the first axis, so that when the box cover 20 rotates, the elastic expansion member 30 can rotate with respect to the box body 10 and the box cover 20, respectively.

When the box cover 20 rotates, the sliding block 34 also rotates along with the connecting shaft 23 about the first axis, and if the second connecting member 32 is fixedly connected to the sliding block 24, the second connecting member 32 also rotates along with the sliding block 34 about the first axis, which causes the second connecting member 32 and the first connecting member 31 to shift in a direction perpendicular to the extending and retracting direction of the elastic member 33 (for convenience of description, the direction perpendicular to the extending and retracting direction of the elastic member 33 is defined as the first direction), and further causes the elastic member 33 to bend and deform, when the elastic member 33 bends and deforms, the elastic member 33 is prone to fatigue failure, which greatly reduces the compression performance and the service life of the elastic member 33, or in some cases, the first connecting member 31 and the second connecting member 32 are also locked. And through rotating second connecting piece 32 and slider 34 and being connected, when lid 20 rotated, make second connecting piece 32 and slider 34 also be for rotating the connection, make second connecting piece 32 and slider 34's rotation offset the effect that connecting axle 23 drove slider 34 and rotate, so can reduce first connecting piece 31 and second connecting piece 32 skew in the first direction, thereby can reduce elastic component 33 and take place bending deformation, the possibility that elastic component 33 produced fatigue failure has been reduced, be favorable to improving the compression performance and the life of elastic component 33, can also avoid the dead condition of first connecting piece 31 and second connecting piece 32 card. Of course, in other embodiments, the elastic expansion element 30 may be integrally formed as an elastic structure, and the elastic expansion element 30 may be fixedly connected to the slider 34.

When the first connecting end is located on the side of the rotation axis (first axis) of the box cover 20 close to the opening, in the closed state, the connecting shaft 23 extends in the direction away from the opening, that is, the connecting shaft 23 extends downward, and at this time, the slider 34 is located on the connecting shaft 23. When the box cover 20 is gradually rotated to be opened, the connecting shaft 23 can be gradually rotated upward in a clockwise direction, so that the elastic expansion piece 30 is gradually compressed, and the slider 34 can slide in a direction approaching the first axis along the connecting shaft 23. When the connecting shaft 23 is perpendicular to the elastic extensible member 30 (refer to fig. 7 and 8), the amount of compression of the elastic extensible member 30 reaches a maximum value or approaches a maximum value, and the slider 34 is still spaced from the stopper. When the box cover 20 is rotated continuously, the elastic expansion piece 30 is elastically restored to drive the sliding block 34 to slide continuously in the direction close to the first axis until the box cover 20 rotates to the completely opened state, the sliding block 34 abuts against the limiting part, and at this time, the elastic expansion piece 30 is not completely restored and still in the compressed state, so that the box cover 20 has the tendency of keeping open. So rotate through connecting elastic expansion piece 30 and slider 34, rotate slider 34 and connecting axle 23 again and be connected, promoted relative motion's flexibility ratio between elastic expansion piece 30 and the lid 20, improved lid 20 pivoted reliable performance, can further reduce the dead condition of card between elastic expansion piece 30, lid 20 and the box body 10 and take place.

In one embodiment, the connecting shaft 23 has a first end 231, a second end 232, and a limiting member (not shown) disposed between the first end 231 and the second end 232, the first end 231 is connected to the box cover 20, and the sliding block 34 is disposed between the limiting member and the second end 232. In the closed state, the slider 34 abuts against the stopper, and the elastic expansion piece 30 is in a compressed state, so that the lid 20 tends to keep the lid closed with the box 10. Specifically, the connecting shaft 23 extends in a direction away from the opening, and at least the second end 232 of the connecting shaft 23 is located on a side of the first axis away from the opening. In the closed state, the slider 34 is located on the side of the first axis far from the opening, and at this time, the elastic expansion piece 30 is in a compressed state and abuts against the limiting piece, and has an acting force for driving the connecting shaft 23 and the box cover 20 to rotate in the counterclockwise direction, so that the box cover 20 has a tendency of keeping the box body 10 closed. At this time, in order to switch the lid 20 from the closed state to the open state, an external force needs to be applied to overcome the urging force of the elastic expansion piece 30 against the lid 20 until the lid 20 is switched from the closed state to the open state. So can reduce lid 20 and rotate and the condition of opening by oneself when closing the lid state, greatly made things convenient for the user to accomodate wireless earphone. The limiting element may be disposed at the second end 232, or may be disposed at a portion of the connecting shaft 23 between the first end 231 and the second end 232. In other embodiments, the elastic member 33 of the elastic expansion member 30 may be in a free state or a stretched state, and the slider 34 may be located on the connecting shaft 23 in the closed state.

In one embodiment, the box cover 20 has a rotating portion 22 rotatably connected to the box body 10, the earphone box further includes a rotating shaft, the rotating portion 22 is sleeved on the rotating shaft and rotatably connected to the rotating shaft, the connecting shaft is rotatably connected to the box body 10, and the connecting shaft 23 is disposed on the rotating portion 22. Specifically, lid 20 is including the portion of closing 21 that is used for closing box body 10, and the portion of closing 21 is connected with rotation portion 22, and the portion of closing 21 and connecting axle 23 locates the double-phase offside of rotation portion 22, and connecting axle 23 extends towards the direction that deviates from portion of closing 21 from rotation portion 22, and the extending direction of connecting axle 23 and the tangential direction of rotation portion 22 are roughly parallel to be set up, and when closing the lid state promptly, connecting axle 23 is vertical downwardly extending. Compare in with connecting axle 23 setting in the portion 21 that closes of lid to when extending to the portion 22 that rotates the portion one side that deviates from the portion 21 that closes of lid, locate connecting axle 23 and can reduce the length of connecting axle 23 on the portion 22 that rotates, thereby can increase the rigidity of connecting axle 23, can also reduce the occupation space of connecting axle 23, be favorable to improving the compact structure nature of earphone box. Of course, in other embodiments, the connecting shaft 23 may be connected to a portion of the covering portion 21 close to the rotating portion 22. In addition, the extending direction of the connecting shaft 23 and the tangential direction of the rotating portion 22 may be inclined, that is, the connecting shaft 23 is gradually inclined toward the side of the rotating portion 22 close to the elastic extensible member 30 in the extending direction away from the opening in the closed state.

In one embodiment, the rotating portion 22 is located in the receiving cavity 13. Specifically, the lid portion 21 has the connection section 211, the connection section 211 is connected with the rotation portion 22, and the connection section 211 is connected to the side of the rotation portion 22 that deviates from the elastic expansion piece 30, so under the state of closing the lid, when the surface of the connection section 211 that deviates from and accepts the cavity 13 is roughly level with the surface of the box body 10, can guarantee that the rotation portion 22 is located and accept the cavity 13, even the lid 20 rotates, also can guarantee that the rotation portion 22 is located and accept the cavity 13 all the time, can avoid the rotation portion 22 to bulge out in the surface of earphone box, thereby avoid the rotation portion 22 to be worn out or even damaged.
