[0051] In the embodiments of the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting", "fixing" and the like should be understood in a broad sense, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements. For those 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.

[0052] The earphone box is a container specially designed to store earphones, which is convenient to carry and protects the earphones from damage. It not only has a storage function, but also can charge the earphones. However, when the user needs to use the earphones, the user needs to put his fingers into the earphone box to take out the earphones, which is not convenient to use and the user experience is poor.

[0053] To solve the above technical problems, the present application provides an earphone box, which introduces a pop-up mechanism to enable the user to more conveniently take out the earphones from the earphone box, thereby improving the convenience and interest in the use of the earphones.

[0054] In one embodiment, refer to Figures 1 to 8 As shown, the earphone case provided in this application includes: a case body 1 and a pop-out mechanism 2. The case body 1 is used to accommodate a first earphone 3 and a second earphone 4. The pop-out mechanism 2 includes a first bracket 5, a second bracket 6, and a rotating disk 7. The first bracket 5 includes a first support 8 and a first rack 9 disposed within the case body 1. The first support 8 is used to support the first earphone 3, and the first rack 9 is connected to the first support 8 along the height direction X of the case body 1. The second bracket 6 includes a second support 10 and a second rack 11 disposed within the case body 1. The second support 10 is used to support the second earphone 4, and the second rack 11 is connected to the second support 10 along the height direction X.

[0055] The rotating disk 7 includes a drive disk body 12 rotatably connected to the side of the housing 1 and a transmission gear 13. The transmission gear 13 is connected to the drive disk body 12, and a transmission tooth 14 is provided on a portion of the peripheral wall of the transmission gear 13 between the first rack 9 and the second rack 11. The transmission tooth 14 is used to mesh with the first rack 9 or the second rack 11 to pop out the first earphone 3 or the second earphone 4.

[0056] In this embodiment, the housing 1 serves as the basic frame of the entire device, providing storage space for the first earphone 3 and the second earphone 4.

[0057] In the pop-out mechanism 2, each bracket includes a support for supporting the corresponding earphone, and the rack of each bracket is connected to the corresponding support along the height direction X of the housing 1; the rotating disk 7 can be a one-piece molded structure. When the user wants to remove the earphone, he rotates the drive disk 12 of the rotating disk 7, which drives the transmission gear 13 to rotate. Since there are transmission teeth 14 on part of the peripheral wall of the transmission gear 13, when it rotates, it will selectively engage with one of the two racks and disengage from the other according to the direction of rotation, thereby popping out the corresponding earphone.

[0058] like Figure 1 and Figure 2 As shown, when using Figure 2 Counterclockwise (i.e.) Figure 1 When the drive disc 12 is rotated clockwise, the transmission teeth 14 of the transmission gear 13 mesh with the second rack 11, causing the second support 10 to rise, thereby lifting the second earphone 4 and ejecting it from the housing 1; at this time, the transmission teeth 14 of the transmission gear 13 disengage from the first rack 9, and the first support 8 remains stationary. Conversely, if... Figure 2 clockwise (i.e.) Figure 1 Rotating the drive disc 12 (reverse pointer) causes the first support 8 to rise, causing the first earphone 3 to pop out, while the second support 10 remains stationary.

[0059] Therefore, the earphone box provided by the embodiment of the present application can quickly pop out the required earphone from the earphone box by simply rotating the rotating disc 7. This design not only simplifies the process of taking out the earphone, but also increases the fun of use.

[0060] In one embodiment, referring to Figure 2 , the transmission gear 13 is a half gear, and the peripheral wall of the half gear includes a first arc wall 15 and a second arc wall 16 with equal arc lengths. In the height direction X, the first arc wall 15 is higher than the second arc wall 16, and the second arc wall 16 is provided with the transmission teeth 14.

[0061] In this embodiment, the peripheral wall of the half gear is divided into two parts, wherein the first arc wall 15 is not provided with the transmission teeth 14, and the second arc wall 16 is provided with the transmission teeth 14. The two arc walls have equal arc lengths, and the first arc wall 15 is higher than the second arc wall 16. That is, the lower half of the peripheral wall of the half gear is provided with the transmission teeth 14, and the first rack 9 and the second rack 11 are symmetrically distributed on the left and right sides of the transmission teeth 14.

[0062] It can be understood that, due to the design of the half gear, it can selectively engage with one of the racks and naturally separate from the other rack during rotation. When the half gear rotates, the transmission teeth 14 on the second arc wall 16 will engage with the corresponding rack to push the corresponding bracket to rise, and the first arc wall 15 without teeth will be in contact with the other rack. At this time, since there is no transmission teeth 14, no engagement occurs, and the corresponding bracket will not move.

[0063] Therefore, the use of the half gear in the embodiment of the present application can achieve precise control of the earphone, ensuring that only one earphone is popped out each time, and improving the safety and convenience of user experience.

[0064] In one embodiment, referring to Figure 1 and Figure 2 , the peripheral wall of the driving disc body 12 is provided with a sawtooth structure 17.

[0065] The sawtooth structure 17 can increase the surface roughness, so that the user's fingers can more firmly hold the driving disc body 12, especially in the case of wet hands. This helps to prevent slipping and ensures that the user can easily rotate the driving disc body 12, thereby improving the convenience of use.

[0066] In one embodiment, referring to Figures 1 to 4 , the side surface of the box body 1 is provided with a mounting groove 18, the center of the mounting groove 18 is provided with a connecting shaft 19, the driving disc body 12 and the transmission gear 13 are concentrically arranged, and the centers of the driving disc body 12 and the transmission gear 13 are provided with a connecting hole 20 rotatably connected to the connecting shaft 19. The transmission gear 13 is arranged in the mounting groove 18, and the driving disc body 12 is arranged on the outer side of the transmission gear 13 away from the mounting groove 18.

[0067] In this embodiment, the connecting shaft 19 on the box body 1 can provide a stable rotating support point for the rotating disc 7. Since the driving disc body 12 and the transmission gear 13 of the rotating disc 7 are concentrically arranged and fixed by the connecting shaft 19, it means that the user only needs to rotate the driving disc body 12 to effectively control the rotation of the transmission gear 13, thereby triggering the ejection mechanism of the earphone. This intuitive operation greatly improves the user experience.

[0068] Moreover, the connecting shaft 19 is provided with a fastening hole 21, and a fastener 22 such as a screw can be passed through the connecting hole 20 and fastened with the fastening hole 21 of the connecting shaft 19, so as to stably fix the rotating disc 7 on the box body 1.

[0069] The transmission gear 13 is located in the mounting groove 18, which can protect the transmission gear 13 from the external environment, prolong the service life, and also improve the compactness of the overall structure, which is conducive to the overall miniaturization design. In addition, since the transmission gear 13 is hidden in the mounting groove 18, it also helps to maintain the simplicity and beauty of the appearance of the earphone box.

[0070] The driving disc body 12 is arranged on the outer side of the transmission gear 13 away from the mounting groove 18, and directly faces the user. Such an arrangement allows the user to directly contact and operate the driving disc body 12 without the need to open an additional cover or perform other complex actions, effectively simplifying the user's operation steps and improving the convenience of use.

[0071] Therefore, the embodiments of the present application achieve the compactness and miniaturization of the earphone box structure through ingenious structural layout, while taking into account the operational convenience of the user.

[0072] In one embodiment, referring to Figures 1 to 6 As shown in the figure, the box body 1 is provided with a first slot 23 accommodating the first earphone 3 and a second slot 24 accommodating the second earphone 4; the box body 1 is also provided with a first guide groove 25 and a second guide groove 26, the first guide groove 25 is provided with a first support 8 and a first rack 9, and the second guide groove 26 is provided with a second support 10 and a second rack 11; the first support 8 extends into the first slot 23, the first rack 9 has a first tooth 27 extending into the mounting groove 18 for meshing with the transmission tooth 14; the second support 10 extends into the second slot 24, and the second rack 11 has a second tooth 28 extending into the mounting groove 18 for meshing with the transmission tooth 14.

[0073] In this embodiment, the first slot 23 and the second slot 24 are arranged side by side, and are respectively used to accommodate the first earphone 3 and the second earphone 4. Such a design allows each earphone to have an independent space, avoiding interference between each other, and also facilitating the user to identify and select.

[0074] Each guide slot is provided with a corresponding support platform and a rack for guiding the lifting of the entire bracket. This guiding mechanism ensures that the bracket moves in a straight line during lifting or lowering, preventing tilting or jamming, thereby ensuring that the earphones can be smoothly and reliably ejected.

[0075] Each support platform extends into the corresponding slot to support and lift the earphones in the corresponding slot. This design not only provides stable support for the earphones, but also allows the earphones to be smoothly ejected under the action of the support platform.

[0076] Each rack has teeth extending into the mounting slot 18 for engaging the drive teeth 14 on the drive gear 13. This ensures that when the drive disc 12 is twisted, the corresponding bracket can be precisely controlled to lift or lower by the drive gear 13, achieving the ejection action of the earphones.

[0077] Therefore, the embodiment of the present application integrates mechanical components in a compact space, particularly the layout of the guide slot, support platform, rack, and drive gear 13, so that the entire earphone case can be made smaller and more portable. Moreover, the stability and reliability of the earphone ejection process can be ensured by the guide slot structure, reducing the risk of earphone damage due to mechanical failure.

[0078] In one embodiment, referring to Figures 2 to 6 As shown in the figure, the first guide slot 25 is provided with a first limiting boss 29 and a second limiting boss 30. The first limiting boss 29 is used to structure the first guide slot 25 into a first slot 31 adapted to the first support platform 8 and a second slot 32 adapted to the first rack 9. The first slot 31 is in communication with the first slot 23, and the second slot 32 is in communication with the mounting slot 18. The first support platform 8 is located between the first limiting boss 29 and the second limiting boss 30.

[0079] In this embodiment, the first limiting boss 29 separates the first guide slot 25 into two first and second slots 31 and 32 that are in communication with each other. The first slot 31 can be in communication with the first slot 23 through a first through-hole 33 on the side, allowing the first support platform 8 to extend into the first slot 23 through the first through-hole 33 to provide stable support for the first earphone 3. The second slot 32 can be in communication with the mounting slot 18 through a second through-hole 34 on the side, ensuring that the first teeth 27 on the first rack 9 can smoothly extend into the mounting slot 18 through the second through-hole 34 and engage with the drive teeth 14 of the drive gear 13.

[0080] The second limiting boss 30 works together with the first limiting boss 29 to define the movement range of the first support platform 8, preventing it from deviating or exceeding the predetermined path during lifting or lowering, and ensuring the accuracy and stability of the movement of the first support platform 8.

[0081] Therefore, the design of the limiting boss in the embodiment of the application ingeniously utilizes the limited space in the first guide groove 25, realizes the function division of multiple grooves, enables the first supporting table 8 and the first rack 9 to smoothly slide in the respective grooves, and improves the compactness of the overall structure, which is conducive to the miniaturization design of the earphone box.

[0082] In one embodiment, referring to Figure 1 and Figure 2 , the bottom of the box body 1 is detachably connected with a bottom cover 35, and the second limiting boss 30 is fixed on the bottom cover 35.

[0083] Specifically, the bottom cover 35 can be connected with the box body 1 through screws, buckles or other structures, and through the detachable design, the installation and maintenance of the internal components can be facilitated.

[0084] In addition, the top of the box body 1 is provided with an openable top cover (not shown in the figure), which can close the first slot 23 and the second slot 24 to protect the first earphone 3 and the second earphone 4.

[0085] When the earphone needs to be used, the top cover can be opened, and then the rotating disc 7 is screwed to pop out the earphone, and when it is not used, the top cover can be closed to protect the earphone.

[0086] In one embodiment, referring to Figures 2 to 6 , the second guide groove 26 is provided with a third limiting boss 36 and a fourth limiting boss 37, the third limiting boss 36 is used to structure the second guide groove 26 into a third groove 38 matched with the second supporting table 10 and a fourth groove 39 matched with the second rack 11, the third groove 38 is in communication with the second slot 24, and the fourth groove 39 is in communication with the mounting groove 18; the second supporting table 10 is arranged between the third limiting boss 36 and the fourth limiting boss 37.

[0087] In this embodiment, the third limiting boss 36 divides the second guide groove 26 into two third groove 38 and fourth groove 39 which are in communication with each other. The third groove 38 can be in communication with the second slot 24 through a third through hole 40 on the side, allowing the second supporting table 10 to extend into the second slot 24 through the third through hole 40 to provide stable support for the second earphone 4. The fourth groove 39 can be in communication with the mounting groove 18 through a fourth through hole 41 on the side, ensuring that the second teeth 28 on the second rack 11 can smoothly extend into the mounting groove 18 through the fourth through hole 41 and mesh with the driving teeth 14 of the transmission gear 13.

[0088] The fourth limiting boss 37 can be fixed on the bottom cover 35 and work together with the third limiting boss 36 to jointly limit the movement range of the second supporting table 10, prevent it from deviating or exceeding the predetermined path during lifting, and ensure the accuracy and stability of the movement of the second supporting table 10.

[0089] Therefore, the design of the limiting boss in this embodiment of the application cleverly utilizes the limited space in the second guide groove 26 to realize the functional division of multiple channels, so that the second support 10 and the second rack 11 can slide smoothly in their respective channels, and improve the compactness of the overall structure, which is conducive to the miniaturization design of the headphone box.

[0090] In one embodiment, refer to Figures 2 to 4 , Figure 7 As shown, the headphone case also includes a torsion spring 42 sleeved on the connecting shaft 19. The torsion spring 42 has a first free end 43 and a second free end 44. A first limiting part 45 and a second limiting part 46 are provided in the mounting groove 18. The first limiting part 45 and the second limiting part 46 are located on the upper and lower sides of the torsion spring 42 along the height direction X, and are used to limit the torsion spring 42. The first limiting part 45 is higher than the second limiting part 46. The left and right ends of the second limiting part 46 are provided with a first limiting surface 47 and a second limiting surface 48 extending along the length direction Y of the case body 1. The middle part of the transmission gear 13 is provided with a receiving hole 20. The groove 49 contains a third limiting part 50 sleeved outside the first limiting part 45 and a fourth limiting part 51 sleeved outside the second limiting part 46. The left and right ends of the fourth limiting part 51 are provided with a third limiting surface 52 and a fourth limiting surface 53 extending along the length direction Y. The third limiting surface 52 is adjacent to the first limiting surface 47, and the fourth limiting surface 53 is adjacent to the second limiting surface 48. The first free end 43 abuts against the first limiting surface 47 and the third limiting surface 52, and the second free end 44 abuts against the second limiting surface 48 and the fourth limiting surface 53. This is the initial position of the free end of the torsion spring 42.

[0091] It is understandable that the first free end 43 and the second free end 44 of the torsion spring 42 are both in a pre-compressed state, possessing a certain pre-compressed force, to provide the necessary elastic restoring force for subsequent operations.

[0092] like Figure 7 As shown, when the user rotates the rotating disc 7 counterclockwise to pop out the earphones, the first free end 43 of the torsion spring 42 rotates counterclockwise and is compressed along with the third limiting surface 52 of the fourth limiting part 51 in the transmission gear 13. At this time, the first free end 43 separates from the first limiting surface 47 of the second limiting part 46 in the mounting groove 18. The second free end 44 continues to abut against the second limiting surface 48 of the second limiting part 46 and remains in the same position. At this time, the second free end 44 separates from the fourth limiting surface 53 of the fourth limiting part 51.

[0093] After the external force is removed, due to the preload of the first free end 43 of the torsion spring 42, the rotating disk 7 will be subjected to torque and rotate clockwise back to its initial position. Figure 2At this time, the transmission teeth 14 of the lower half of the transmission gear 13 are located between the first rack 9 and the second rack 11 and are separated from both racks, in preparation for the next operation. The reverse is the same, and details are not repeated here.

[0094] Therefore, the automatic return-to-zero reset function of the rotating disc 7 can be realized through the design of the torsional spring 42, so as to drive the corresponding bracket to reset, thereby simplifying the operation steps of the user and improving the convenience and efficiency of use. Moreover, the design of the torsional spring 42 and the related limiting components ingeniously utilizes the limited space inside the earphone box, realizes the integration of multiple components, ensures the coordinated operation between the components, maintains the compactness of the overall structure, and is conducive to the miniaturization design of the earphone box.

[0095] In one embodiment, referring to Figures 2 to 4 As shown, the shapes of the first limiting portion 45, the second limiting portion 46, the third limiting portion 50, and the fourth limiting portion 51 are all arc-shaped. In this way, the stability and reliability of the rotation of the rotating disc 7 can be improved.
