[0041] Please refer to Figure 1 The wireless earphone 1000 of the present application embodiment comprises the earphone charging bin 100 and the earphone body 200 of any embodiment of the present application, and the earphone body 200 is accommodated in the accommodation cavity 30.

[0042] In this way, the protruding part 101 can not only provide damping effect during the rotation of the cover 20, but also enhance the connection strength between the cover 20 and the damping part 40, so as to provide additional holding force when the earphone charging bin 100 is subjected to drop impact, reduce the possibility of accidental opening of the cover 20, and reduce the risk of dropping the earphone body 200.

[0043] Specifically, the earphone charging bin 100 can be used to protect the earphone body 200, provide a convenient storage method, and charge the earphone body 200 when needed. For example, a wireless charging coil or a metal contact point can be integrated in the earphone charging bin 100 for charging the earphone body 200. The earphone body 200 can include components such as a sound generating unit, a circuit board, a battery, etc. of the earphone. The earphone body 200 can be used to play audio and receive sound. The earphone body 200 can be designed as an in-ear type, a semi-in-ear type or other forms.

[0044] Please refer to Figure 2 , Figure 3 ,Figure 4 and Figure 5 The earphone charging bin 100 in the embodiment of the utility model comprises a shell 10, a cover 20 and a damping piece 40. The cover 20 and the shell 10 enclose a containing cavity 30, the cover 20 is rotatably connected with the shell 10 to close or open the containing cavity 30; the damping piece 40 is connected with the shell 10 and is arranged between the shell 10 and the cover 20; wherein one of the cover 20 and the damping piece 40 comprises a protruding part 101, the protruding part 101 is protruded on the outer surface of one of the cover 20 and the damping piece 40 and is in contact with the other one of the cover 20 and the damping piece 40.

[0045] In the earphone charging bin 100 in the embodiment of the utility model, the damping piece 40 is arranged between the shell 10 and the cover 20, and the cover 20 and the damping piece 40 are in contact with each other through the protruding part 101, which can realize the damping effect of the cover 20 in the rotating process, so that the cover 20 can hover at any angle, improving the flexibility and convenience of use. At the same time, the protruding part 101 can keep the connection between the cover 20 and the shell 10 stable under the impact of the earphone charging bin 100 falling and the like, preventing accidental separation between the cover 20 and the shell 10. In addition, the width and contact area and other parameters of the protruding part 101 can be adjusted, so that the damping strength can be adjusted at low cost, and the length of the protruding part 101 can be adjusted to adjust the damping range.

[0046] Specifically, the shell 10 refers to the external structure constituting the earphone charging bin 100, which can be used to protect the earphone body 200 and other accessories arranged inside the earphone charging bin 100. The containing cavity 30 can be used to contain the earphone body 200 and other accessories. The containing cavity 30 can be provided with charging contacts or magnetic attraction devices for charging and fixing the earphone body 200.

[0047] The cover 20 can be matched with the shell 10 to close or open the containing cavity 30. The cover 20 can be rotated towards the direction away from the shell 10 to open the containing cavity 30. The cover 20 can also be rotated towards the direction close to the shell 10 to close the containing cavity 30. The cover 20 can be rotatably connected with the shell 10 by using hinges, rotating shafts 11 or spherical joints and the like.

[0048] The damping member 40 can be connected with the shell 10 by bonding, buckling or screwing, etc. The damping member 40 can be used to reduce or control the opening and closing speed of the cover 20, and provide a smooth opening and closing experience. The damping member 40 can be a component that can play a damping role. Through the damping effect of the damping member 40, damping force can be applied to the cover 20 when the cover 20 rotates relative to the shell 10, so as to control the rotation process of the cover 20 in cooperation with the action of the user's finger part. The number of damping members 40 can be one or more to adapt to different damping needs. The damping member 40 can be made of rubber, silicone or other materials that can play a damping role.

[0049] The protruding part 101 can be protruded on the outer surface of the cover 20. The protruding part 101 can also be protruded on the outer surface of the damping member 40. The protruding part 101 can be a structure such as a rib, a bump or a rib. The protruding part 101 can be a regular shape such as a cylinder or a prism, or an irregular shape. The protruding part 101 is used to enhance the damping effect between the cover 20 and the damping member 40. When the protruding part 101 contacts one of the cover 20 and the damping member 40, friction can be generated, and the protruding part 101 can be deformed, thereby being able to play a damping role. The protruding part 101 can be made of the same material as the damping member 40, or can be made of different materials. For example, the protruding part 101 can also be made of rubber, silicone or other materials that can play a damping role.

[0050] In the related art, if the damping member 40 is provided, the contact area between the cover 20 and the shell 10 needs to be reduced, so that the cover 20 can contact the damping member 40 to achieve the damping effect. However, the utility model embodiment does not reduce the contact area between the cover 20 and the shell 10, but realizes the damping effect between the cover 20 and the damping member 40 through the protruding part, thereby ensuring the structural stability of the cover 20 when rotating to the maximum opening position, and maintaining the structural strength of the cover 20.

[0051] By providing the damping member 40 and setting the protruding part 101 to contact one of the cover 20 and the damping member 40, the damping effect is realized. The cover 20 can not only move to the position of closing the accommodating cavity 30, but also move to the maximum position of opening the accommodating cavity 30, and can also hover at any position between closing the accommodating cavity 30 and opening the accommodating cavity 30 to realize the hovering function of the cover 20. When the cover 20 hovers at any position between closing the accommodating cavity 30 and opening the accommodating cavity 30, the protruding part 101 contacts one of the cover 20 and the damping member 40 to generate friction, so that the cover 20 and the damping member 40 remain relatively stationary to realize the hovering function of the cover 20.

[0052] Figures 3 to 11 Different states of the earphone charging box 100 are shown. Among them,Figure 3 、 Figure 4 and Figure 5 shows the closed state of the earphone charging case 100. Figure 6 、 Figure 7 and Figure 8 shows one open state of the earphone charging case 100. Figure 9 、 Figure 10 and Figure 11 shows another open state of the earphone charging case 100. It should be noted that the open states of the earphone charging case 100 are not limited to Figures 6 to 11 shown, Figures 6 to 11 which are only examples for easy understanding. According to different rotation angles of the cover 20 relative to the shell 10, the earphone charging case 100 can also present other open states.

[0053] Please refer to Figure 5 、 Figure 8 and Figure 11 In some embodiments, the damping member 40 includes a mounting surface 41 and a protrusion 101, the mounting surface 41 is arranged towards the cover 20, and the protrusion 101 is protruded from one side of the mounting surface 41 and in contact with the cover 20.

[0054] In this way, the protrusion 101 arranged on the damping member 40 has a simple manufacturing process and low manufacturing cost. At the same time, the protrusion 101 occupies a small space, which is conducive to improving the overall space utilization of the earphone charging case 100.

[0055] Specifically, the mounting surface 41 can be a plane or a curved surface formed on the damping member 40. For example, the mounting surface 41 can be an arc-shaped curved surface, and the curvature of the arc-shaped curved surface gradually increases in the rotation direction of the cover 20 from the closed accommodation cavity 30 to the open accommodation cavity 30. The protrusion 101 and the mounting surface 41 can be integrally formed, for example, the protrusion 101 and the mounting surface 41 can be integrally formed by injection molding. In this way, the protrusion 101 and the mounting surface 41 formed in this way have no joints or seams between them, which reduces potential weak points, thereby improving the overall structural strength of the protrusion 101 and the mounting surface 41, so that the protrusion 101 can continuously contact the cover 20, thereby continuously providing damping effect.

[0056] Please refer to Figure 5 、 Figure 8 and Figure 11 In some embodiments, one of the cover 20 and the shell 10 includes a rotation shaft 11, and the other is provided with a mounting hole 21, the rotation shaft 11 is arranged through the mounting hole 21 and rotationally matched with the mounting hole 21.

[0057] Thus, one of the cover 20 and the shell 10 comprises the rotating shaft 11, and the other is provided with the mounting hole 21, and the rotating shaft 11 is arranged in the mounting hole 21 and rotationally connected with the mounting hole 21, so as to realize the rotation connection of the cover 20 relative to the shell 10. The design of the rotating shaft 11 and the mounting hole 21 allows the cover 20 to maintain stable rotation performance in long-term use, reduces wear, and thus prolongs the service life of the earphone charging bin 100. Moreover, the manufacturing process of the rotating shaft 11 and the mounting hole 21 is simple, and the cost is low.

[0058] Specifically, the rotating shaft 11 can be driven to rotate freely in the mounting hole 21. For example, when the user applies a force to the cover 20, the rotating shaft 11 can rotate in the clockwise or counterclockwise direction in the mounting hole 21. The mounting hole 21 can be manufactured by machining, casting or injection molding, and the like, and the utility model embodiment is not limited thereto.

[0059] The rotating shaft 11 can be arranged on the cover 20 or on the shell 10. The mounting hole 21 can be arranged on the cover 20 or on the shell 10.

[0060] Please refer to Figure 5 , Figure 8 and Figure 11 . In some embodiments, the shell 10 comprises the rotating shaft 11, and the cover 20 is provided with the mounting hole 21.

[0061] The shell 10 can provide a more stable support point, reduce the shaking caused by the rotation of the cover 20, and enhance the stability of the overall structure. Moreover, the design of the shell 10 comprising the rotating shaft 11 makes the assembly process simpler, and the assembly can be completed by simply aligning the mounting hole 21 of the cover 20 with the rotating shaft 11 of the shell 10.

[0062] Please refer to Figure 4 , Figure 7 and Figure 10 . In some embodiments, the cover 20 comprises the upper cover 22 and the inner support 23 connected with the upper cover 22, the shell 10 comprises the lower shell 12 and the middle shell 13 connected with the lower shell 12, the inner support 23 and the middle shell 13 are arranged between the lower shell 12 and the upper cover 22, the inner support 23 is rotationally connected with the middle shell 13, the inner support 23 has the first accommodating cavity 230, the middle shell 13 has the second accommodating cavity 130 arranged correspondingly to the first accommodating cavity 230, one end of the second accommodating cavity 130 is closed, the other end of the second accommodating cavity 130 is provided with the first opening 131, one end of the first accommodating cavity 230 is closed, the other end of the first accommodating cavity 230 is provided with the second opening 231 arranged correspondingly to the first opening 131, and the accommodating cavity 30 comprises the first accommodating cavity 230 and the second accommodating cavity 130.

[0063] Therefore, the rotatable connection between the inner shell 23 and the middle shell 13 allows the cover 20 of the earphone charging case 100 to rotate relative to the shell 10, which provides additional flexibility for the opening and closing mechanism of the charging case. By arranging the first accommodating cavity 230 and the second accommodating cavity 130 and corresponding to each other, the charging case can more effectively utilize the internal space and provide more storage positions for earphones and other accessories.

[0064] The first accommodating cavity 230 of the inner shell 23 and the second accommodating cavity 130 of the middle shell 13 are closed at one end, and the inner shell 23 and the middle shell 13 are arranged between the lower shell 12 and the upper cover 22, which can provide additional protection for the earphones and other accessories stored inside and reduce damage caused by falling or impact.

[0065] In addition, the inner shell 23 can support the upper cover 22, thereby improving the overall structural strength of the cover 20 and reducing the probability of shaking of the cover 20 during rotation.

[0066] Specifically, the upper cover 22 and the inner shell 23 can be connected by snap connection, threaded connection, etc., or can be connected by one-piece molding. The lower shell 12 and the middle shell 13 can be connected by snap connection, threaded connection, etc., or can be connected by one-piece molding. The first accommodating cavity 230 and the second accommodating cavity 130 can be customized in shape according to requirements. For example, the first accommodating cavity 230 and the second accommodating cavity 130 can match the shape of the earphone body 200.

[0067] Please refer to Figure 5 , Figure 8 , Figure 11 , and Figure 12 and Figure 13 . In some embodiments, the middle shell 13 includes a mounting portion 132 spaced from the second accommodating cavity 130, and the mounting portion 132 is connected with the damping member 40.

[0068] Therefore, since the mounting portion 132 is spaced from the second accommodating cavity 130, the second accommodating cavity 130 is less likely to be affected during rotation of the inner shell 23 or the middle shell 13, thereby reducing the probability of interference between the inner shell 23 and the earphones and other accessories accommodated in the second accommodating cavity 130. Moreover, since the middle shell 13 is arranged between the lower shell 12 and the upper cover 22, the mounting portion 132 of the middle shell 13 is less likely to be affected by external environmental factors, thereby improving the durability of the earphone charging case 100.

[0069] Specifically, the mounting portion 132 can be located on the side of the second accommodating cavity 130 close to the damping member 40. The number of the mounting portion 132 and the damping member 40 can be one or more. The mounting portion 132 and the damping member 40 can be connected by threaded connection, clamping, bonding, etc.

[0070] Please refer to Figure 12 and Figure 13 In some embodiments, the number of the mounting portions 132 and the number of the dampening members 40 are both plural, and the mounting portions 132 and the dampening members 40 are arranged in the length direction L of the earphone charging bin 100 in a one-to-one correspondence.

[0071] In this way, by arranging the mounting portions 132 and the dampening members 40 in a one-to-one correspondence, the uniform distribution of the damping force during the opening and closing of the charging bin cover 20 can be achieved, and the uneven movement of the inner holder 23 caused by uneven damping can be avoided.

[0072] Specifically, the number of the mounting portions 132 can be two, three, four, or even more. The number of the dampening members 40 can be two, three, four, or even more. For example, the number of the mounting portions 132 and the number of the dampening members 40 are both two, and the two mounting portions 132 and the two dampening members 40 are arranged in the length direction L of the earphone charging bin 100 in a one-to-one correspondence.

[0073] In some embodiments, the mounting portions 132 and the dampening members 40 are bonded.

[0074] In this way, by using bonding to connect the mounting portions 132 and the dampening members 40, the assembly process of the earphone charging bin 100 can be simplified. The bonding method can reduce the loosening of components caused by vibration or long-term use, thereby enhancing the durability of the charging bin and prolonging its service life. Bonding connection can reduce the micro-motion between the mounting portions 132 and the dampening members 40, and reduce the noise and vibration caused by friction or impact between components.

[0075] Specifically, the mounting portions 132 and the dampening members 40 can be bonded with adhesives such as back adhesive, epoxy resin, and silicone adhesive. For example, the mounting portions 132 and the dampening members 40 can be bonded with back adhesive, which can be pressure-sensitive adhesive. The pressure-sensitive adhesive can be bonded to the surface of the adherend under slight pressure, without the need for additional curing time or conditions, which is conducive to the rapid bonding of the mounting portions 132 and the dampening members 40. The pressure-sensitive adhesive has reversibility, that is, the pressure-sensitive adhesive can be easily removed without leaving residue or damaging the surface of the adherend, which is conducive to the disassembly of the mounting portions 132 and the dampening members 40. The pressure-sensitive adhesive can be bonded by slight pressure, but the pressure-sensitive adhesive can provide long-term bonding effect, and can remain stable even under various environmental conditions, so as to maintain stable connection between the mounting portions 132 and the dampening members 40.

[0076] Please refer to Figure 5 、 Figure 8 、 Figure 11In some embodiments, the middle shell 13 comprises a mounting portion 132, the mounting portion 132 is provided with a mounting groove 1320, the mounting groove 1320 is recessed on one side of the mounting portion 132 in a direction away from the cover 20, the mounting groove 1320 and the inner holder 23 form a third accommodating cavity 102, and the damping member 40 is arranged in the third accommodating cavity 102.

[0077] In this way, by arranging the mounting groove 1320 on the mounting portion 132 of the middle shell 13 and arranging the damping member 40 in the third accommodating cavity 102, the layout of the damping member 40 in the earphone charging box 100 can be optimized to be more compact and concentrated, and the occupation of the internal space of the earphone charging box 100 can be reduced.

[0078] In addition, the mounting groove 1320 is recessed on one side of the mounting portion 132 in a direction away from the cover 20, which can provide a larger mounting space for the damping member 40.

[0079] Please refer to Figure 5 、 Figure 8 、 Figure 11 In some embodiments, the damping member 40 comprises a protruding portion 101, the inner holder 23 comprises a covering portion 232 and a rotating portion 233 connected with the covering portion 232, the covering portion 232 has a first accommodating cavity 230, the rotating portion 233 and the mounting groove 1320 form a third accommodating cavity 102, and the rotating portion 233 is in contact with the protruding portion 101.

[0080] In this way, the rotating portion 233 and the protruding portion 101 will generate friction during contact, which can achieve the damping effect between the rotating portion 233 and the protruding portion 101, so as to achieve the damping effect of the covering portion 232 during rotation, so that the covering portion 232 can hover at any angle, improving the flexibility and convenience of use. In addition, the first accommodating cavity 230 and the third accommodating cavity 102 are respectively formed by different parts of the inner holder 23, which makes the structure of the earphone charging box 100 compact.

[0081] Specifically, the rotating portion 233 and the protruding portion 101 can generate friction due to contact, thereby being able to provide a damping effect to enable the cover 20 to hover at any angle.

[0082] Please refer to Figure 5 、 Figure 8 、 Figure 11 In some embodiments, the protruding portion 101 interferes with the other one of the cover 20 and the damping member 40.

[0083] In this way, the interference enables the cover 20 to maintain contact with the damping member 40 during rotation, which can enhance the damping effect of the cover 20 during rotation, thereby reducing the probability of failure of the hovering function of the cover 20.

[0084] Specifically, the protrusion 101 abuts against the other one of the cover 20 and the damping member 40. When in contact with the cover 20 or the damping member 40, the protrusion 101 can be in a deformed state. For the case that the cover 20 comprises the protrusion 101, during the rotation of the cover 20, the outer surface of the cover 20 will constantly interfere with the protrusion 101, the protrusion 101 will be elastically deformed, and friction will be generated between the protrusion 101 and the outer surface of the cover 20, thereby achieving the damping effect.

[0085] In some embodiments, the interference amount between the protrusion 101 and the other one of the cover 20 and the damping member 40 ranges from [0.3, 0.7] mm. For example, the interference amount can range from [0.3, 0.6] mm, [0.4, 0.6] mm, [0.3, 0.5] mm, [0.5, 0.6] mm, [0.4, 0.7] mm, etc. The interference amount can be 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, etc.

[0086] In this way, by controlling the interference amount between the protrusion 101 and the other one of the cover 20 and the damping member 40 within the range of [0.3, 0.7] mm, it can be ensured that the connection between the cover 20 and the damping member 40 is neither too loose nor too tight, thereby ensuring the stability of the connection, and thus ensuring that the damping member 40 provides uniform and stable damping force during the opening and closing of the cover 20, thereby improving the damping performance.

[0087] Please refer to Figure 5 , Figure 8 , Figure 11 In some embodiments, the protrusion 101 is a rib. In this way, designing the protrusion 101 as a rib can significantly enhance the structural strength of the protrusion 101, making the protrusion 101 more capable of bearing various stresses during use and improving the durability of the protrusion 101.

[0088] Specifically, the rib can be manufactured by injection molding, extrusion, or 3D printing, etc. The damping strength can be adjusted at low cost by adjusting the width of the rib and the interference amount. The damping range can be adjusted by adjusting the length of the rib.
