[0053] The present invention provides an earphone charging box 100.

[0054] Reference Figure 1 and Figure 6 In an embodiment of the present invention, the earphone charging box 100 includes an outer shell 10, an inner shell 20, an upper cover 30 and a linkage mechanism 40. The inner shell 20 is movably connected to the outer shell 10, and the inner shell 20 is provided with an earphone 200 accommodating cavity 11; the upper cover 30 is slidably arranged on the inner shell 20, and the upper cover 30 can slide to open or slide to close the earphone 200 accommodating cavity 11; the linkage mechanism 40 connects the outer shell 10, the inner shell 20 and the upper cover 30, and the inner shell 20 moves relative to the outer shell 10 through the linkage mechanism 40, and drives the upper cover 30 to slide through the linkage mechanism 40.

[0055] Among them, the outer shell 10 is mainly used to carry components such as the inner shell 20, and its shape can be a regular shape such as a rectangle for easy carrying, which is not limited in this application. In order to avoid the overall weight of the earphone charging box 100 being too heavy and inconvenient for users to carry, the material of the outer shell 10 and the inner shell 20 can be plastic (such as ABS, POM, PS, PMMA, PC, PET, PBT, PPO, etc.), that is, the support and protection provided will not make the overall weight of the earphone charging box 100 too heavy. Of course, the material of the outer shell 10 and the inner shell 20 can also be metal to improve the service life of the earphone charging box 100. It should be noted that the earphone charging box 100 can drive the inner shell 20 to move relative to the outer shell 10 through an electric structure, or it can drive the inner shell 20 to move relative to the outer shell 10 through a mechanical structure. The earphone 200 accommodating cavity 11 can be an integral chamber to place two earphones 200 at the same time, so as to facilitate the processing of the inner shell 20. Of course, the earphone 200 accommodating chamber 11 can also be two independent chambers to place two earphones 200 respectively, which is convenient for users to take out. The specific selection can be made by those skilled in the art. In addition, the earphone charging box 100 can be closed by directly pushing the upper cover 30 to slide closed, or by driving the inner shell 20 to move so that the upper cover 30 slides to close the earphone 200 accommodating chamber 11.

[0056] The earphone charging box 100 of the technical solution of the present invention comprises an outer shell 10 and an inner shell 20 movably connected to the outer shell 10, the inner shell 20 is provided with an earphone 200 accommodating cavity 11, and the earphone charging box 100 also comprises a linkage mechanism 40 and an upper cover 30 slidably arranged on the inner shell 20, the upper cover 30 can slide to open or slide to close the earphone 200 accommodating cavity 11, and the linkage mechanism 40 connects the outer shell 10, the inner shell 20 and the upper cover 30. Thus, by making the inner shell 20 move relative to the outer shell 10 under the action of the linkage mechanism 40, the user can simultaneously drive the upper cover 30 to slide through the linkage mechanism 40 to open the earphone 200 accommodating cavity 11, so that the user can open the cover without touching the upper cover 30, which is more convenient to use, and allows the user to obtain a brand new box opening experience, increase the selectivity of the earphone charging box 100, and improve the user's experience of use.

[0057] Reference Figures 1 to 7 In one embodiment of the present application, a mounting cavity 14 with an opening is formed in the outer shell 10, and the inner shell 20 is movably disposed in the mounting cavity 14 and reciprocates in the opening of the mounting cavity 14; when the inner shell 20 slides out of the opening of the mounting cavity 14, the inner shell 20 drives the linkage mechanism 40 to drive the upper cover 30 to slide open the earphone 200 accommodating cavity 11. The inner shell 20 can be installed in the mounting cavity 14 of the outer shell 10 through the opening, so that the outer shell 10 can be circumferentially arranged around the inner shell 20 to play a protective role. The inner shell 20 can reciprocate along the opening of the installation cavity 14, so that when the inner shell 20 slides out of the opening of the installation cavity 14, the inner shell 20 drives the linkage mechanism 40 to drive the upper cover 30 to slide open the earphone 200 accommodating cavity 11, so that the user can take the earphone 200 from the earphone 200 accommodating cavity 11 of the inner shell 20 without touching the upper cover 30. At the same time, the inner shell 20 extends out of the outer shell 10, which is more convenient for the user to take the earphone 200. When the upper cover 30 is driven to cover the earphone 200 accommodating cavity 11 again to cover the earphone 200, the inner shell 20 is simultaneously and completely accommodated in the installation cavity 14 of the outer shell 10, which can not only ensure that the inner shell 20 is covered and protected by the outer shell 10 as a whole, but also effectively avoid the earphone charging box 100 from occupying too much volume after the box is closed, thereby improving the usability of the earphone charging box 100.

[0058] Furthermore, the collection reference Figure 8The linkage mechanism 40 includes a first rack 41, a driving gear 42 and a second rack 43. The first rack 41 is connected to the outer shell 10; the driving gear 42 is rotatably connected to the inner shell 20, and the driving gear 42 is meshed with the first rack 41; the second rack 43 is connected to the upper cover 30, and the second rack 43 is meshed with the driving gear 42, so that the first rack 41 and the second rack 43 can both drive the driving gear 42 to rotate, so as to synchronously drive the upper cover 30 to slide open or slide close the earphone 200 accommodating chamber 11. The linkage mechanism 40 adopts the method of meshing of racks and gears for transmission, and the transmission method is relatively stable, that is, when the inner shell 20 moves toward the opening of the installation chamber 14 of the outer shell 10, the first rack 41 drives the driving gear 42 to rotate, so that the driving gear 42 drives the second rack 43 to move to synchronously drive the cover plate to slide to open the earphone 200 accommodating chamber 11. When the upper cover 30 is driven to close the earphone 200 accommodating cavity 11, the upper cover 30 slides to make the second rack 43 drive the driving gear 42 to rotate, so that the driving gear 42 drives the first rack to move, so as to drive the inner shell 20 to move along the opening of the installation cavity 14 away from the outer shell 10, so as to complete the closing process. It should be noted that the first rack 41 can be an integral structure with the outer shell 10, and the second rack 43 can be an integral structure with the upper cover 30, which not only reduces the number of parts, but also reduces the labor of assembly and reduces costs, while ensuring the strength of the overall structure of the first rack 41 and the second rack 43, so that the transmission between the gears and the first rack 41 and the second rack 43 is relatively stable. Of course, the linkage mechanism 40 can also be a ball screw or other structure, and the specific setting can be set by those skilled in the art according to the specific situation.

[0059] Furthermore, the side wall surface of the inner shell 20 is recessed to form a clearance groove 21, and the inner shell 20 is protruding with a rotating shaft 24 in the clearance groove 21, and the driving gear 42 is sleeved on the rotating shaft 24; it can be understood that by recessing the clearance groove 21 on the side wall surface of the inner shell 20, an escape space is formed for the installation of the driving gear 42, and the driving gear 42 can be sleeved on the rotating shaft 24 located in the clearance groove 21, so as to avoid the driving gear 42 occupying more space in the outer shell 10, so that the assembly between the inner shell 20 and the outer shell 10 can be more compact, so that the volume of the earphone charging box 100 is smaller, which is more convenient for users to carry.

[0060] Optionally, in conjunction with reference Figure 3 and Fig.10The inner shell 20 is provided with a guide channel 22 on the surface facing the upper cover 30, and the guide channel 22 extends in the direction in which the upper cover 30 opens the earphone 200 accommodating cavity 11, and the second rack 43 includes a meshing portion 431, a connecting portion 432, and a guiding portion 433, wherein the meshing portion 431 is meshed and connected with the driving gear 42, the connecting portion 432 is connected with the upper cover 30, and the guiding portion 433 is connected with the meshing portion 431 and the connecting portion 432 respectively, and the guiding portion 433 is embedded in the guide channel 22. The meshing portion 431, the connecting portion 432, and the guiding portion 433 are provided as an integrated structure to ensure the strength of the overall structure of the second rack 43. By providing a guide channel 22 on the inner shell 20, the guide portion 433 of the second rack 43 can be embedded in the guide channel 22, so that the second rack 43 can be guided by the guide channel 22 to move in a directional manner, thereby ensuring the stability of the upper cover 30 in opening and closing the earphone 200 accommodating cavity 11. In addition, the inner shell 20 is also provided with an auxiliary channel, the extension direction of which is the same as the extension direction of the guide channel 22, and the upper cover 30 is provided with an auxiliary slider on the side facing the inner shell 20, the auxiliary slider can partially pass through the auxiliary channel and be limited to the side of the inner shell 20 away from the upper cover 30, so as to achieve the effect of preventing the upper cover 30 from separating from the inner shell 20, and the auxiliary slider slides in the auxiliary channel to further ensure the directional movement of the second rack 43, so as to improve the stability of the upper cover 30 in opening and closing the earphone 200 accommodating cavity 11. Of course, the upper cover 30 and the inner shell 20 can also be connected by means of sliders and slide rails.

[0061] In one embodiment of the present application, the earphone charging box 100 also includes a lifting mechanism, which is arranged in the mounting cavity 14 of the outer shell 10 to drive the inner shell 20 to slide back and forth relative to the opening of the mounting cavity 14. Among them, the lifting mechanism is installed in the mounting cavity 14, and the lifting mechanism can be a driving mechanism such as a motor or a cylinder to drive the inner shell 20 to move relative to the outer shell 10, so as to further facilitate the user's operation and improve the user's experience. Of course, the lifting mechanism can also be driven by a purely mechanical structure, which can not only make the internal structure of the earphone charging box 100 compact to reduce the volume of the earphone charging box 100, but also make the cost of the earphone charging box 100 relatively low and easy to produce. The specific setting can be made by those skilled in the art according to the specific situation.

[0062] Furthermore, in conjunction with reference Figures 2 to 5 ,as well as Figure 7The lifting mechanism includes a lifting elastic member 51, a stop block 52 and a limiting member 53. The lifting elastic member 51 is embedded in the installation cavity 14 of the outer shell 10 and is connected to the inner shell 20 so that the inner shell 20 can be relatively close to or away from the opening of the installation cavity 14; the stop block 52 is connected to the inner shell 20; the limiting member 53 is movably connected to the outer shell 10, and the limiting member 53 moves relative to the inner shell 20 to be detachably abutted with the stop block 52; when the upper cover 30 closes the earphone 200 accommodating cavity 11, the limiting member 53 abuts against the stop block 52 to limit the lifting elastic member 51 from lifting the inner shell 20, and when the upper cover 30 opens the earphone 200 accommodating cavity 11, the limiting member 53 is separated from the stop block 52. In one embodiment, the lifting elastic member 51 can be a spring or made of elastic materials such as silicone, that is, when the upper cover 30 closes the earphone 200 accommodating chamber 11, the limiting member 53 abuts against the stop block 52 to limit the position, so that the inner shell 20 is restricted from moving, so that the inner shell 20 is fixed and abuts against the lifting elastic member 51 to be pressed and deformed; and when it is necessary to open the earphone 200 accommodating chamber 11, the limiting member 53 is driven to move to separate from the stop block 52, so that the inner shell 20 can move again, and then the pressed lifting elastic member 51 will reset to elastically lift the inner shell 20, and drive the upper cover 30 to open the earphone 200 accommodating chamber 11 through the linkage mechanism 40, so as to achieve the driving of the inner shell 20 to move to synchronously drive the linkage mechanism 40 and the upper cover 30 to move, so as to open or close the upper cover 30. It should be noted that the limiting member 53 can be moved by pure mechanical drive or by motor drive, which can be selected by those skilled in the art.

[0063] Furthermore, in conjunction with the reference Fig. 9The lifting mechanism further includes a reset elastic member 54. The housing 10 is provided with a clearance opening 12 connected to the installation cavity 14. The reset elastic member 54 is respectively connected to the housing 10 and the limiting member 53, so that the limiting member 53 can be relatively inserted into or extended from the clearance opening 12 to be in contact with or separated from the stop block 52. The reset elastic member 54 can be the same as the lifting elastic member 51, that is, it can be a spring or made of elastic materials such as silicone. At the same time, in order to ensure the stability of the installation of the reset elastic member 54, a fixing block 13 is provided on the inner wall surface of the housing 10. The fixing block 13 is provided with a fixing groove 131 for the reset elastic member 54 to be placed, so as to ensure the stability of the reset elastic member 54 when it is in contact. The specific opening shape of the clearance opening 12 is not limited, so that part of the limiting member 53 can pass through the outer shell 10. In this way, the user can press the limiting member 53 from the outside of the clearance opening 12 of the outer shell 10 of the earphone charging box 100 to make the limiting member 53 abut against and press the reset elastic member 54, and at the same time separate the limiting member 53 from the stop block 52, so that the inner shell 20 will be lifted by the lifting elastic member 51 to drive the upper cover 30 to open the earphone 200 accommodating cavity 11. After opening, the reset elastic member 54 will reset to push the limiting member 53 back to its original position for reopening next time. In this way, the opening method of the purely mechanical structure can make the internal structure more compact, so that the volume of the earphone charging box 100 can be designed to be relatively small, and at the same time, the production cost can be effectively reduced.

[0064] Understandable, combined with reference Figure 7 The inner shell 20 is provided with a clearance opening 23, and the clearance opening 23 extends along the moving direction of the inner shell 20. The limiting member 53 passes through the clearance opening 23 and extends out of the clearance port 12. The inner shell 20 moves relative to the outer shell 10, so that the limiting member 53 reciprocates relative to the clearance opening 23. In order to prevent the inner shell 20 from moving up and down too much and completely separating from the outer shell 10, a clearance opening 23 is provided in the inner shell 20 for the limiting member 53 to pass through. In this way, the limiting member 53 is accommodated and limited in the clearance opening 23 to limit the moving distance of the inner shell 20, thereby ensuring the normal opening and closing process of the earphone charging box 100.

[0065] Furthermore, in conjunction with reference Figure 4A guide slope 521 is provided on a side of the stop block 52 away from the opening of the installation cavity 14. When the inner shell 20 moves in a direction away from the opening of the installation cavity 14, the guide slope 521 is used to guide the limit member 53 to move in a direction away from the stop block 52. When the upper cover 30 is opened and the earphone 200 accommodating cavity 11 is closed again, the upper cover 30 is driven to move so that the linkage mechanism 40 drives the inner shell 20 to move downward. At this time, the stop block 52 is located above the limit member 53. When the stop block 52 abuts against the limit member 53 again, the inner shell 20 is moved downward. The guide bevel 521 is provided to automatically drive the limit member 53 to move in the direction of separation from the stop block 52, that is, to move in the direction of pressing the reset elastic member 54, so that the limit block of the inner shell 20 is separated from the limit member 53, so that the stop block 52 of the inner shell 20 can move to the bottom of the limit member 53, and the limit member 53 is re-contacted with the stop block 52 under the reset action of the reset elastic member 54, so as to achieve the effect of closing the earphone 200 accommodating cavity 11. By providing the guide bevel 521, the user's operation difficulty is reduced and the usability of the earphone charging box 100 is improved.

[0066] Optionally, refer to Figure 5 The position-limiting member 53 includes a contact block 531 and a plug-in block 532 connected to each other. The plug-in block 532 sequentially passes through the clearance port 12 and the clearance passage 23 and is connected to the reset elastic member 54. The contact block 531 is used to limit the contact with the stop block 52. It can be understood that the contact block 531 and the plug-in block 532 can be an integrated structure, that is, the installation process is omitted, and the overall structural strength of the position-limiting member 53 is ensured. Of course, the plug-in block 532 and the contact block 531 can also be connected in a detachable manner such as a buckle, so as to facilitate later maintenance and replacement. The plug-in block 532 can sequentially pass through the clearance port 12 and the clearance passage 23 and abut against the reset elastic member 54, and the plug-in block 532 can be connected to the side wall of the plug-in block 532, so as to abut against the stop block 52. It should be noted that in order to further enhance the effect of the stop abutment, a plurality of abutment blocks 531 may be provided, and a plurality of stop blocks 52 may also be provided, so that abutment between the abutment blocks 531 and the stop blocks 52 can be enhanced. The specific number of the abutment blocks 531 and the stop blocks 52 may be set by technicians in this field according to the specific circumstances and will not be elaborated here.

[0067] In one embodiment of the present application, refer to Figure 1 and Figure 6, the number of the upper covers 30 is two, and both of the upper covers 30 are slidably arranged on the inner shell 20; the number of the linkage mechanisms 40 is two, one of the linkage mechanisms 40 is respectively connected to one of the upper covers 30 and the inner shell 20, and the other linkage mechanism 40 is respectively connected to the other upper cover 30 and the inner shell 20, and the inner shell 20 moves relative to the outer shell 10 to drive the two linkage mechanisms 40 to drive the two upper covers 30 to move closer to or away from each other. Among them, by setting two upper covers 30 and transmitting them respectively through two linkage mechanisms 40 at the same time, not only the moving efficiency of each upper cover 30 is relatively stable, but also the structure of one group can be replaced independently later. The opening and closing method of the earphone charging box 100 makes the two upper covers 30 abut or separate from the middle, so that the user can directly take the earphone 200 from the middle of the earphone charging box 100. This opening and closing method makes the taking process more convenient, and also makes the overall opening and closing method of the earphone charging box 100 more beautiful.
