[0059] TWS earphones are becoming increasingly popular. Due to their convenience, charging cases that accommodate both the earphones and the battery compartment are becoming increasingly popular. However, depending on user preference and habits, some users prefer to wear only the left earbud or only the right earbud.

[0060] In related technologies, wireless earphones are placed in a compartment to electrically connect the earphones to the battery in the compartment, while a cover protects the earphones placed inside the compartment. However, this design exposes both earphones when the cover is opened, preventing them from opening according to user needs. Furthermore, charging boxes typically use a magnet and a hinged structure for opening and closing, resulting in a relatively simple opening method.

[0061] Based on the above concepts and problems, the present invention proposes a charging box 100. It can be understood that the charging box 100 is used to store the earphones 500, and the charging box 100 is also used to charge the earphones 500. The charging box 100 of the present invention provides users with a brand-new way to open the earphone charging box. By pushing the upper cover 3 in a horizontal push manner, the opening 12 of the charging box 100 is opened, thereby facilitating the user to take only the left earphone 500 or the right earphone 500 according to personal preference, thereby achieving single-handed removal of the earphones 500.

[0062] Please refer to Figures 1 to 5 As shown, in the embodiment of the present invention, the charging box 100 includes a bottom shell 1, an earphone compartment 2 and an upper cover 3. The bottom shell 1 is provided with a mounting cavity 11 and an opening 12 communicating with the mounting cavity 11. The earphone compartment 2 includes a first earphone compartment 21 and a second earphone compartment 22. The first earphone compartment 21 and the second earphone compartment 22 are spaced apart and movably arranged in the mounting cavity 11. The first earphone compartment 21 and the second earphone compartment 22 are both provided with a placement groove 23, and the placement groove 23 is used to place the earphone 500. The upper cover 3 is movably connected to the first earphone compartment 21 and the second earphone compartment 22 through a linkage component 4, and is movably connected. The cover is closed at the opening 12; wherein, the charging box 100 has an open state in which the upper cover 3 is translated relative to the bottom shell 1 to open part of the opening 12, and a covered state in which the opening 12 is covered; in the covered state, the first earphone compartment 21 and the second earphone compartment 22 are both retracted into the installation cavity 11; in the open state, the upper cover 3 has a first position and a second position, in the first position, the first earphone compartment 21 extends out of the opening 12, and the second earphone compartment 22 is retracted into the installation cavity 11, and in the second position, the second earphone compartment 22 extends out of the opening 12, and the first earphone compartment 21 is retracted into the installation cavity 11.

[0063] In this embodiment, the bottom shell 1 of the charging case 100 is used to mount, secure, and protect components such as the earphone compartment 2, upper cover 3, and linkage assembly 4. That is, the bottom shell 1 provides a mounting base for these components. It will be appreciated that the bottom shell 1 has a mounting cavity 11 for mounting and accommodating components such as the earphone compartment 2 and linkage assembly 4. Optionally, the bottom shell 1 is cylindrical or box-shaped with one end open.

[0064] It is understandable that the shape of the bottom shell 1 can be designed according to actual needs, such as a rectangular parallelepiped, a cube, a sphere or an ellipsoid, etc., and is not limited here. In this embodiment, in order to facilitate the charging function of the charging box 100, a power supply component is also provided in the bottom shell 1 of the charging box 100. The specific details can be referred to the existing technology and are not limited here.

[0065] It should be noted that the earphone compartment 2 is used to provide a space for holding, placing, accommodating or charging the earphones 500. In order to facilitate the storage of the earphones 500, the earphone compartment 2 is provided with a placement slot 23 for placing the earphones 500. It can be understood that the shape and contour of the placement slot 23 are similar to the outer contour of the earphones 500. For details, please refer to the existing technology and are not limited here. In order to facilitate the charging of the earphones 500 in the placement slot 23, the slot wall of the placement slot 23 is provided with a power supply contact piece, and the earphones 500 are provided with a charging contact, which are not limited here.

[0066] Optionally, the earphone compartment 2 can be an integrated structure or a split structure. In this embodiment, to facilitate the user to pick up the earphones 500 and to enable the user to pick up a single earphone according to their own preferences and needs, the earphone compartment 2 includes a first earphone compartment 21 and a second earphone compartment 22, which are separated and movably arranged in the installation cavity 11.

[0067] In this embodiment, a linkage component 4 is provided so that the upper cover 3 is movably connected to the first earphone compartment 21 and the second earphone compartment 22 respectively through the linkage component 4, so that the upper cover 3 can be movably closed at the opening 12. In this way, the charging box 100 can have an open state in which the upper cover 3 is translated relative to the bottom shell 1 to open part of the opening 12 and a closed state in which the opening 12 is closed.

[0068] It can be understood that by the user pushing the upper cover 3 horizontally, the upper cover 3 can be translated relative to the bottom shell 1 to open part of the opening 12 or cover the opening 12. In this way, when the user pushes the upper cover 3 horizontally, the upper cover 3 can be translated to drive the first earphone compartment 21 or the second earphone compartment 22 to move in the installation cavity 11 of the bottom shell 1 through the linkage component 4.

[0069] In this embodiment, when a user pushes the upper cover 3 horizontally relative to the bottom shell 1 to partially open the opening 12, the upper cover 3 can have a first position and a second position relative to the bottom shell 1 according to different pushing directions. It can be understood that the direction in which the upper cover 3 moves from the closed state to the first position is defined as the first direction, and the direction in which the upper cover 3 moves from the closed state to the second position is defined as the second direction. The first direction and the second direction are parallel and opposite to each other.

[0070] It should be noted that when the user pushes the upper cover 3 horizontally in the first direction relative to the bottom shell 1 to open the partial opening 12, the upper cover 3 and the partial opening 12 on the bottom shell 1 are enclosed to form a first pick-and-place opening, which is directly opposite to the first earphone compartment 21, so that when the upper cover 3 moves, it is convenient to drive the linkage component 4 to pull the first earphone compartment 21 to move to the first pick-and-place opening or extend out of the first pick-and-place opening, so as to facilitate the user to take the single earphone 500 in the first earphone compartment 21.

[0071] Of course, when the user pushes the upper cover 3 horizontally in the second direction relative to the bottom shell 1 to open the partial opening 12, the upper cover 3 and the partial opening 12 on the bottom shell 1 are enclosed to form a second pick-up and release port, which is directly opposite to the second earphone compartment 22, so that when the upper cover 3 moves, it is convenient to drive the linkage component 4 to pull the second earphone compartment 22 to the second pick-up and release port or extend it out of the second pick-up and release port, so as to facilitate the user to take the single earphone 500 in the second earphone compartment 22.

[0072] In this embodiment, the movement direction of the upper cover 3 is set at an angle to the movement direction of the first earphone compartment 21 or the second earphone compartment 22. Optionally, the movement direction of the upper cover 3 is set perpendicular to the movement direction of the first earphone compartment 21 or the second earphone compartment 22, that is, the first direction and the second direction are both set perpendicular to the movement direction of the first earphone compartment 21 or the second earphone compartment 22.

[0073] The charging box 100 of the present invention is achieved by separating and movably arranging the first earphone compartment 21 and the second earphone compartment 22 of the earphone compartment 2 in the installation cavity 11 of the bottom shell 1, and providing a placement groove 23 in the first earphone compartment 21 and the second earphone compartment 22, so that the earphone 500 is placed in the placement groove 23, and at the same time, the upper cover 3 is movably connected to the first earphone compartment 21 and the second earphone compartment 22 through the linkage component 4, so that the upper cover 3 is movably covered on the opening 12 of the bottom shell 1, so that the charging box 100 can have an open state in which the upper cover 3 is translated relative to the bottom shell 1 to open part of the opening 12 and a closed state in which the opening 12 is covered. In the closed state, the first earphone compartment 21 and the second earphone compartment 22 are both It shrinks into the installation cavity 11, thereby realizing the storage or charging of the earphone 500; and in the open state, by pushing in different directions, the upper cover 3 has a first position and a second position. When the upper cover 3 is pushed to the first position, the upper cover 3 pulls the first earphone compartment 21 out of the opening 12 through the linkage component 4, and the second earphone compartment 22 is still shrinked in the installation cavity 11; when the upper cover 3 is pushed to the second position, the upper cover 3 pulls the second earphone compartment 22 out of the opening 12 through the linkage component 4, and the first earphone compartment 21 shrinks into the installation cavity 11, so that the charging box 100 can realize the taking of a single earphone according to the different preferences or needs of the user, thereby improving the opening method of the charging box 100.

[0074] In one embodiment, the bottom shell 1 is further provided with a first limiting groove 131 and a second limiting groove 132 located in the mounting cavity 11, and at least a portion of the first earphone compartment 21 is slidably accommodated in the first limiting groove 131, and at least a portion of the second earphone compartment 22 is slidably accommodated in the second limiting groove 132; wherein, the slot direction of the first limiting groove 131 is the same as the moving direction of the first earphone compartment 21, and the slot direction of the second limiting groove 132 is the same as the moving direction of the second earphone compartment 22.

[0075] In this embodiment, if Figures 2 to 5As shown, by providing a first limiting groove 131 and a second limiting groove 132 in the mounting cavity 11 of the bottom shell 1, the first limiting groove 131 and the second limiting groove 132 are used to limit the installation of the first earphone compartment 21 and the second earphone compartment 22 while not affecting the movement of the first earphone compartment 21 and the second earphone compartment 22. It can be understood that the first limiting groove 131 and the second limiting groove 132 are used to limit the first earphone compartment 21 and the second earphone compartment 22 in the moving direction of the horizontally pushed upper cover 3, that is, the first limiting groove 131 and the second limiting groove 132 can limit the first earphone compartment 21 and the second earphone compartment 22 in the first direction and the second direction, thereby preventing the first earphone compartment 21 and the second earphone compartment 22 from shaking or other problems.

[0076] It is understood that a middle shell is disposed within the mounting cavity 11 of the bottom shell 1, and a structure such as positioning ribs or positioning plates is formed on the middle shell, so that multiple positioning ribs or positioning plates enclose the first limiting groove 131 and the second limiting groove 132. The positioning ribs or positioning plates can be a single integral structure, enclosing a groove structure. Of course, the positioning ribs or positioning plates can also be multiple convex ribs or plate-like structures, which enclose a groove structure, but this is not limited here.

[0077] To facilitate the user's ability to push the upper cover 3 horizontally, the upper cover 3 drives the linkage assembly 4 to pull the first earphone compartment 21 / second earphone compartment 22 relative to the first limiting slot 131 / second limiting slot 132, and the first limiting slot 131 / second limiting slot 132 do not affect the movement of the first earphone compartment 21 / second earphone compartment 22. In this embodiment, the notch direction of the first limiting slot 131 is the same as the movement direction of the first earphone compartment 21, that is, the depth direction of the first limiting slot 131 is the same as the movement direction of the first earphone compartment 21. The notch direction of the second limiting slot 132 is the same as the movement direction of the second earphone compartment 22, that is, the depth direction of the second limiting slot 132 is the same as the movement direction of the second earphone compartment 22.

[0078] It can be understood that in order to prevent the first earphone compartment 21 / the second earphone compartment 22 from completely separating from the first limiting groove 131 / the second limiting groove 132, the depth of the first limiting groove 131 / the second limiting groove 132 is greater than or equal to the moving height of the first earphone compartment 21 / the second earphone compartment 22.

[0079] Optionally, in order to further prevent the first earphone compartment 21 / the second earphone compartment 22 from completely separating from the first limiting groove 131 / the second limiting groove 132, a limiting boss is provided at the position adjacent to the slot of the first limiting groove 131 / the second limiting groove 132, and a limiting stop or limiting groove and other structures are provided at the bottom of the first earphone compartment 21 / the second earphone compartment 22.

Of course, the second connecting rod 42 of the linkage assembly 4 can also be a single rod-shaped, plate-shaped, strip-shaped, or rod-shaped structure. Of course, the second connecting rod 42 can also be a chain-shaped structure in which multiple rod-shaped, plate-shaped, strip-shaped, or rod-shaped structures are movably connected together, etc., without limitation here.

[0084] In this embodiment, by movably connecting one end of the first connecting rod 41 to the upper cover 3 and rotatably connecting the other end of the first connecting rod 41 to the first earphone compartment 21, it is possible to conveniently use the first connecting rod 41 to pull the first earphone compartment 21 for movement while avoiding problems such as jamming during the pulling process of the first connecting rod 41. It is understandable that by movably connecting one end of the second connecting rod 42 to the upper cover 3 and rotatably connecting the other end of the second connecting rod 42 to the second earphone compartment 22, it is possible to conveniently use the second connecting rod 42 to pull the second earphone compartment 22 for movement while avoiding problems such as jamming during the pulling process of the second connecting rod 42.

[0085] Alternatively, as Figures 2 to 5 As shown, a first rotating ring 411 is provided at one end of the first connecting rod 41 adjacent to the first earphone compartment 21, and a first convex column 211 is provided on the outer wall of the first earphone compartment 21. The first rotating ring 411 is rotatably sleeved on the first convex column 211. Figures 2 to 5 As shown, in order to prevent the arrangement of the first protrusion 211 and the first connecting rod 41 from affecting the sliding of the first earphone compartment 21 in the first limiting groove 131, a first avoidance opening 151 is formed in the groove wall of the first limiting groove 131 corresponding to the first protrusion 211. That is, the groove wall of the first limiting groove 131 is formed in the first avoiding opening 151 corresponding to the first connecting rod 41. Optionally, the extension direction of the first avoiding opening 151 is consistent with the movement direction of the first earphone compartment 21.

In other words, a second avoidance opening 152 is formed in the groove wall of the second limiting groove 132 corresponding to the second connecting rod 42. Optionally, the extension direction of the second avoidance opening 152 is consistent with the movement direction of the second earphone compartment 22.

[0087] In one embodiment, the linkage assembly 4 also includes a first elastic member 43 and a second elastic member 44, one end of the first elastic member 43 is connected to the first earphone compartment 21, and the other end of the first elastic member 43 is connected to the bottom shell 1, one end of the second elastic member 44 is connected to the second earphone compartment 22, and the other end of the second elastic member 44 is connected to the bottom shell 1; wherein, in the first position, the first elastic member 43 is stretched when the first earphone compartment 21 extends out of the opening 12; and in the second position, the second elastic member 44 is stretched when the second earphone compartment 22 extends out of the opening 12.

[0088] In this embodiment, if Figures 2 to 5As shown, by providing the first elastic member 43 and the second elastic member 44, the first elastic member 43 / the second elastic member 44 provide elastic restoring force for the reset of the first earphone compartment 21 / the second earphone compartment 22, while improving the closing effect of the upper cover 3. Optionally, the first elastic member 43 and the second elastic member 44 can be telescopic springs or return springs.

[0089] Alternatively, as Figures 2 to 5 As shown, the outer wall of the first earphone compartment 21 is provided with a first connecting ear 212, and the bottom wall of the mounting cavity 11 is provided with a first fixing ear 141. The two ends of the first elastic member 43 are detachably connected to the first connecting ear 212 and the first fixing ear 141, respectively. As can be understood, this arrangement facilitates assembly and disassembly without affecting the arrangement of the first elastic member 43.

[0090] In order to prevent the first connecting ear 212 and the first elastic member 43 from affecting the sliding of the first earphone compartment 21 in the first limiting groove 131, a first avoidance opening 151 is formed in the groove wall of the first limiting groove 131 corresponding to the first connecting ear 212. In other words, a first avoidance opening 151 is formed in the groove wall of the first limiting groove 131 corresponding to the first elastic member 43. Optionally, the extension direction of the first avoidance opening 151 is consistent with the movement direction of the first earphone compartment 21.

[0091] Alternatively, as Figures 2 to 5 As shown, the outer wall of the second earphone compartment 22 is provided with a second connecting ear 221, and the bottom wall of the bottom shell 1 is provided with a second fixing ear 142. The two ends of the second elastic member 44 are respectively detachably connected to the second connecting ear 221 and the second fixing ear 142. It can be understood that this arrangement can facilitate disassembly and assembly without affecting the arrangement of the second elastic member 44.

[0092] To prevent the second connecting ear 221 and the second elastic member 44 from affecting the sliding of the second earphone compartment 22 in the second limiting groove 132, a second avoidance opening 152 is defined in the wall of the second limiting groove 132 corresponding to the second connecting ear 221. In other words, a second avoidance opening 152 is defined in the wall of the second limiting groove 132 corresponding to the second elastic member 44. Optionally, the extension direction of the second avoidance opening 152 is consistent with the movement direction of the second earphone compartment 22.

[0093] It can be understood that the setting of the first elastic member 43 and the second elastic member 44 can not only provide elastic restoring force for the reset of the first earphone compartment 21 / the second earphone compartment 22, but also connect and fix the upper cover 3 through the first earphone compartment 21 / the second earphone compartment 22 and the first connecting rod 41 and the second connecting rod 42, so as to facilitate the movable closing of the upper cover 3 on the opening 12 of the bottom shell 1.

[0094] In one embodiment, in order to avoid interference between the first connecting rod 41 and the second connecting rod 42 , optionally, the first connecting rod 41 and the second connecting rod 42 are located on opposite sides of the upper cover 3 in the translation direction.

[0095] In order to further ensure that the second connecting rod 42 is not affected when the upper cover 3 moves along the first direction, and to ensure that the first connecting rod 41 is not affected when the upper cover 3 moves along the second direction, in one embodiment, the upper cover 3 is provided with a first sliding groove 31 corresponding to the first connecting rod 41, and the linkage assembly 4 also includes a first slider 45 that slides with the first sliding groove 31, and the first slider 45 is rotatably connected to the first connecting rod 41; the upper cover 3 is provided with a second sliding groove 32 corresponding to the second connecting rod 42, and the linkage assembly 4 also includes a second slider 46 that slides with the second sliding groove 32, and the second slider 46 is rotatably connected to the second connecting rod 42.

[0096] In this embodiment, if Figures 2 to 5 As shown, by providing a first sliding groove 31 and a second sliding groove 32 on the upper cover 3 , the first sliding groove 31 and the second sliding groove 32 are utilized to provide avoidance and sliding guidance for the first connecting rod 41 and the second connecting rod 42 respectively.

[0097] It should be noted that the upper cover 3 moves to the left along the first direction, and moves to the right along the second direction. It is understood that when the upper cover 3 moves in the first direction, the first connecting rod 41 is limited by the first slider 45 to the rightmost end of the first chute 31 in the first direction, while the second connecting rod 42 is located at the leftmost end of the second chute 32 by the second slider 46. When the upper cover 3 moves in the first direction, the upper cover 3, through the limited cooperation between the first chute 31 and the first slider 45, drives the first connecting rod 41 to pull the first earphone compartment 21 to move and stretch the first elastic member 43. At this time, the second slider 46 moves from the leftmost end to the rightmost end of the second chute 32. When the upper cover 3 is released, the first elastic member 43 contracts, driving the first earphone compartment 21 and the first connecting rod 41 to pull the upper cover 3 back to the state of covering the opening 12.

[0098] As can be understood, when the upper cover 3 moves in the second direction, the first connecting rod 41 is limited by the first slider 45 to the rightmost end of the first sliding groove 31 in the first direction, while the second connecting rod 42 is located at the leftmost end of the second sliding groove 32 by the second slider 46. When the upper cover 3 moves in the second direction, the upper cover 3, through the limited cooperation between the second sliding groove 32 and the second slider 46, drives the second connecting rod 42 to pull the second earphone compartment 22 to move, and stretches the second elastic member 44. At this time, the first slider 45 moves from the leftmost end to the rightmost end of the second sliding groove 32. When the upper cover 3 is released, the second elastic member 44 contracts, and drives the second earphone compartment 22 and the second connecting rod 42 to pull the upper cover 3 back to the state of covering the opening 12.

[0099] It should be noted that the first chute 31 / the second chute 32 can be a strip groove or a waist groove or the like recessed on the upper cover 3. Of course, the first chute 31 / the second chute 32 can also be a strip groove or a waist groove or the like convexly provided on the upper cover 3 and enclosed by a convex ring, which is not limited here.

Furthermore, / or, the second slider 46 has a second rotation slot, and the second connecting rod 42 has a second rotation axis, which is rotatably disposed in the second rotation slot.

[0101] In this embodiment, if Figure 2 As shown, by setting the first rotation groove 451 / second rotation groove on the first slider 45 / second slider 46, it is convenient to use the first rotation groove 451 / second rotation groove and the first rotation axis / second rotation axis of the first connecting rod 41 / second connecting rod 42 to achieve rotational connection, thereby improving the connection stability.

[0102] In this embodiment, in order to prevent the end of the bottom shell 1 adjacent to the opening 12 from interfering with the convex ring structure forming the first sliding groove 31 / the second sliding groove 32 during the translation of the upper cover 3, in one embodiment, as shown in FIG. Figures 1 to 5 As shown, the bottom shell 1 is provided with a first clearance opening 161 corresponding to the first chute 31, and the upper cover 3 is provided with a first stopper 33 corresponding to the first clearance opening 161. In the closed state, the first stopper 33 is located at the first clearance opening 161. In the second position, the first chute 31 moves through the first clearance opening 161. The bottom shell 1 is provided with a second clearance opening 162 corresponding to the second chute 32, and the upper cover 3 is provided with a second stopper 34 corresponding to the second clearance opening 162. In the closed state, the second stopper 34 is located at the second clearance opening 162. In the first position, the second chute 32 moves through the second clearance opening 162.

[0103] It can be understood that the setting of the first give way opening 161 / the second give way opening 162 can provide avoidance for the first slide groove 31 / the second slide groove 32, and the first block 33 / the second block 34 can be used to seal the first give way opening 161 / the second give way opening 162 to ensure the sealing of the charging box 100.

[0104] In one embodiment, the bottom shell 1 further includes a first positioning platform 171 corresponding to the first slide groove 31. In the first position, one end of the first slide groove 31 abuts against the first positioning platform 171 for position restraint. Furthermore, / or, the bottom shell 1 further includes a second positioning platform 172 corresponding to the second slide groove 32.

[0106] Optionally, the first clearance opening 161 and the second clearance opening 162 are located on opposite sides of the bottom shell 1 and are staggered; the first positioning platform 171 and the second positioning platform 172 are located on opposite sides of the bottom shell 1 and are staggered.

[0107] In this embodiment, if Figures 1 to 5 As shown, the first clearance opening 161 and the first positioning platform 171 are arranged opposite to each other in the moving direction of the upper cover 3 ; the second clearance opening 162 and the second positioning platform 172 are arranged opposite to each other in the moving direction of the upper cover 3 .

[0108] In one embodiment, if Figures 2 to 5 As shown, the upper cover 3 is provided with a positioning protrusion 35 corresponding to each placement slot 23; when the cover is closed, the positioning protrusion 35 abuts against the earphone 500 in the placement slot 23. It can be understood that by providing the positioning protrusion 35 on the upper cover 3, the positioning protrusion 35 can be used to position the earphone 500 in the placement slot 23 in the Z direction (i.e., the movement direction of the first earphone compartment 21 / second earphone compartment 22). This ensures the position of the earphone 500 in the placement slot 23 and ensures the connection stability of the earphone 500 during charging.

[0109] The present invention also provides a TWS headset 600, which includes the above-mentioned charging box 100 and two earphones 500, each earphone 500 being detachably accommodated in a placement slot 23 of the charging box 100.
