[0050] Most current headphone devices come with portable charging cases. Taking wireless Bluetooth headphones as an example, the popularity of wireless Bluetooth headphones is increasing day by day, and wireless Bluetooth headphone charging devices are essential accessories. Currently, the headphone cases of wireless Bluetooth headphones on the market have a relatively simple structure, which is not only inconvenient to store, but also makes the use efficiency of the headphone case low.

[0051] In view of this, the present invention provides an earphone charging case and an earphone device. Figures 1 to 7 Specific embodiments of the earphone charging case provided by the present invention; Figures 8 to 9 Specific embodiments of the headphone device provided by the present invention.

[0052] Please see Figures 1 to 5The earphone charging case 100 includes a shell 1, a base 2, and a position holding structure 4. The shell 1 has an opening at one end in a first direction F1. The base 2 has an earphone charging compartment 21 mounted on it. The base 2 is movably disposed within the shell 1 along the first direction F1. An elastic member 3 is provided between the shell 1 and the base 2, and the elastic member 3 is used to push the base 2 to move along the axial extension direction of the opening. The base 2 has a closed position that is retracted into the shell 1, and a position that extends towards the shell 1. 1. The exposed open position; the position holding structure 4 includes a slider 41 and a groove 42. The slider 41 is movably disposed on one of the inner side of the outer shell 1 and the outer side of the seat 2 along the second direction F2. The groove 42 is disposed on the other of the inner side of the outer shell 1 and the outer side of the seat 2. A first limiting part and a second limiting part are formed on the bottom wall of the groove 42 so that the slider 41 can be correspondingly limited and fixed when the seat 2 is in the closed position and the open position.

[0053] In the technical solution of the present invention, the earphone charging case 100 includes a shell 1, a base 2, and a position holding structure 4; the base 2 is movably disposed within the shell 1 along a first direction F1, and an elastic member 3 is provided between the shell 1 and the base 2 so that the base 2 can move along the axial extension direction of the opening; the base 2 has a closed position retracted into the shell 1 and an open position exposed to the outside of the shell 1; a slider 41 and a groove 42 are correspondingly provided between the inner side of the shell 1 and the outer side of the base 2, the slider 41 can move along the second direction F2, and a first limiting part and a second limiting part are formed on the bottom wall of the groove 42 so that the slider 41 can be correspondingly limited and fixed when the base 2 is in the closed position and the open position; that is, during use, when the user pushes the base 2 to the closed position, the base 2 is retracted into the shell 1. Inside the shell 1, the slider 41 slides along the loop groove 42 to engage with the first limiting part, fixing the seat 2 in the closed position, thus completing the closing action. When it is necessary to open the box, the user pushes the seat 2 inward again to disengage the slider 41 from the first limiting part. At this time, the elastic member 3 pushes the seat 2 to move along the axial extension direction of the opening, pushing the seat 2 to the open position. At this time, the seat 2 is exposed to the outside of the shell 1, and the slider 41 slides along the loop groove 42 to engage with the second limiting part, fixing the seat 2 in the open position, thus completing the opening action. This configuration allows the headphone charging case 100 to not only provide charging and storage functions for the headphones, but also to have an automatic and quick opening and closing function, making the headphone charging case 100 easy to store and highly efficient to use.

[0054] Please see Figure 6 and Figure 7The spiral groove 42 includes a first groove segment 421, a second groove segment 422, a third groove segment 423, and a fourth groove segment 424 connected end to end. The first groove segment 421 and the second groove segment 422 extend obliquely in the second direction F2, while the third groove segment 423 and the fourth groove segment 424 extend obliquely in the first direction F1. The first groove segment 421 and the second groove segment 422 are located near the opening of the mounting cavity. The first limiting portion is located at the position of the first groove segment 421 near the second groove segment 422; the second limiting portion… Located at the connection between the third slot 423 and the fourth slot 424; when the base 2 switches from the open position to the closed position, the slider 41 passes through the fourth slot 424 and the first slot 421 in sequence; when the base 2 switches from the closed position to the open position, the slider 41 passes through the first slot 421, the second slot 422 and the third slot 423 in sequence; this arrangement enables the earphone charging case 100 to also have an automatic and quick opening and closing function, thereby making the earphone charging case 100 easy to store and highly efficient to use.

[0055] Specifically, the first groove segment 421 has a first step 43 formed near the second groove segment 422; a second step 44 is formed at the connection between the third groove segment 423 and the fourth groove segment 424, so that the groove depth of the fourth groove segment 424 is greater than the groove depth of the third groove segment 423; a third step 45 is formed at the connection between the first groove segment 421 and the second groove segment 422, so that the groove depth of the second groove segment 422 is greater than the groove depth of the first groove segment 421; wherein, the first limiting part includes the first step 43; the second limiting part includes the second step 44; that is, during use, when the user pushes the seat 2 to the closed position, the seat 2 is retracted into the outer shell 1. At this time, the slider 41 slides through the fourth groove segment 424 and the first groove segment 421 in sequence, and crosses the first step 43. The first step 43 limits and fixes the slider 41, preventing the slider 41 from returning, so as to fix the seat 2 in the closed position, thereby completing the closing action; when it is necessary to open the box... The user pushes the seat 2 inward again, causing the slider 41 to continue sliding towards the second groove 422. At this time, the slider 41 passes the third step 45, which limits and fixes the slider 41 to prevent it from returning to its original position. At this time, the compression of the elastic element 3 reaches its maximum. When the user releases the seat 2, the elastic element 3 pushes the seat 2 to move along the axial extension direction of the opening, pushing the seat 2 to the opening position. At this time, the seat 2 protrudes outward from the outer shell 1. Furthermore, the slider 41 slides from the second groove segment 422 to the third groove segment 423 and crosses the second step 44. The second step 44 limits and fixes the slider 41 to fix the seat 2 in the opening position, thereby completing the opening action. With this configuration, the headphone charging case 100 not only provides functions such as charging and storing the headphones, but also has the function of automatic and quick opening and closing, making the headphone charging case 100 easy to store and highly efficient to use.

[0056] Meanwhile, the bottom wall of the first groove segment 421 is provided with a transition groove segment 46 near the third step 45. The bottom wall of the transition groove segment 46 forms a guide slope connecting to the third step 45. By providing the transition groove segment 46 and the guide slope on the bottom wall of the transition groove segment 46, the slider 41 can easily cross the third step 45, thereby making it easier for the seat 2 to switch from the closed position to the open position.

[0057] Further reading Figure 3 and Figure 6In this embodiment, the seat 2 extends outward on the side facing the inner wall of the outer shell 1 to form a limiting platform 22. The limiting platform 22 is used to abut against the bottom wall end face of the mounting cavity when the slider 41 passes the third step 45, thereby limiting the seat 2. That is, when it is necessary to open the box, the user pushes the seat 2 inward again so that the slider 41 passes the third step 45. At this time, the limiting platform 22 abuts against the bottom wall end face of the mounting cavity, thereby preventing the seat 2 from moving too inward and making the switching of the seat 2 between the closed position and the open position smoother.

[0058] Please see Figure 9 In this invention, an avoidance groove 11 is provided on the inner wall of the outer shell 1, and an installation groove 12 is provided on the bottom wall of the avoidance groove 11. The installation groove 12 extends longitudinally. One end of the slider 41 is slidably installed in the installation groove 12 laterally. This arrangement makes the structural installation between the outer shell 1 and the base 2 more compact, thereby reducing the space occupied by the earphone charging case 100.

[0059] Specifically, the slider 41 includes a slider cover 411, a slider body 412, and an elastic connector 413; one end of the slider cover 411 is slidably installed in the mounting groove 12; the slider body 412 is disposed opposite to the slider cover 411, and the end of the slider body 412 facing away from the slider cover 411 is slidably installed in the U-shaped groove 42; the two ends of the elastic connector 413 are respectively connected to the opposite ends of the slider cover 411 and the slider body 412; by setting the slider 41 as a segmented type, the movement of the slider 41 is more flexible, thereby making the switching of the seat 2 between the closed position and the open position smoother.

[0060] The present invention does not limit the specific form of the seat 2. Specifically, in this example, the seat 2 includes an outer shell and an inner shell; the outer shell forms a cavity with an opening on one side; the inner shell is disposed in the cavity, and the charging cavity is formed on the inner shell for placing and charging the device; this arrangement makes the structure of the seat 2 more compact, thereby reducing the space occupied by the earphone charging case 100.

[0061] The present invention does not limit the specific form of the outer shell 1. Specifically, in this example, the outer shell 1 includes a shell and a cover. The shell has a cavity with openings on both sides. The cover covers one side opening of the cavity to form the mounting cavity together with the shell. This arrangement makes the structure of the outer shell 1 more compact, thereby reducing the space occupied by the earphone charging case 100.

[0062] Please see Figure 8and Figure 9 The present invention also provides an earphone device 1000, which includes an earphone charging case 100. It should be noted that the earphone charging case 100 is the earphone charging case 100 described above. That is, the earphone device 1000 includes all the technical features of the earphone charging case 100 described above. Since the earphone device 1000 adopts all the technical solutions of all embodiments of the earphone charging case 100 described above, it also has all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0063] Specifically, the headphone device 1000 also includes a wireless earphone 200, which is placed inside the earphone charging case 21 of the headphone charging case 100. This arrangement not only enables the headphone device 1000 to provide charging and storage functions for the wireless earphone 200, but also has an automatic and quick opening and closing function, making the headphone device 1000 easy to store and highly efficient to use.

[0064] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention.
