[0042] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0043] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0044] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0045] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0046] like Figures 1 to 13As shown, this embodiment provides a charging box, which includes a first housing 10, a second housing 20, and a snap-fit ​​mechanism 30. The first housing 10 and the second housing 20 are rotatably connected. A snap-fit ​​block 11 is provided on the first housing 10. The snap-fit ​​mechanism 30 is disposed on the second housing 20. The snap-fit ​​mechanism 30 includes a snap-fit ​​member 31, a driving member 32, and a traction member 33. The snap-fit ​​member 31 is movably disposed on the second housing 20, the driving member 32 is movably disposed on the second housing 20, and the two ends of the traction member 33 are respectively connected to the driving member 32 and the snap-fit ​​member 31. When the first housing 10 is closed on the second housing 20, the snap-fit ​​block 11 corresponds to and cooperates with the snap-fit ​​mechanism 30. The snap-fit ​​member 31 has a locked position. When the first housing 10 is closed on the second housing 20, the snap-fit ​​member 31 is in the locked position and snaps the snap-fit ​​block 11. The driving member 32 is used to drive the snap-fit ​​member 31 away from the locked position through the traction member 33, so that the snap-fit ​​member 31 releases the snap-fit ​​block 11. Specifically, in this embodiment, when the latching member 31 is in the locked position, it can block the latching block 11, thereby limiting the relative rotation of the first housing 10 and the second housing 20, and ensuring the connection stability of the first housing 10 and the second housing 20. The traction member 33 is connected between the latching member 31 and the driving member 32, ensuring effective power transmission. When it is necessary to unlock the first housing 10 and the second housing 20, the driving member 32 can drive the latching member 31 away from the locked position through the traction member 33, thereby causing the latching member 31 to release the latching block 11, and the first housing 10 and the second housing 20 to unlock, ensuring that the first housing 10 and the second housing 20 can be opened normally and ensuring the normal use function of the charging box. Furthermore, since the latching member 31 and the latching block 11 are in a surface contact latching method, it can ensure the stability of the latching. Compared with the buckle structure in the prior art, this surface contact latching method can effectively extend the service life of the charging box and is convenient to unlock.

[0047] Optionally, in one embodiment, as Figure 2 and Figure 3 As shown, the first housing 10 and the second housing 20 are rotatably connected by a pin 41, which can ensure the connection stability of the first housing 10 and the second housing 20. A first torsion spring 42 is provided between the first housing 10 and the second housing 20. The first torsion spring 42 can be configured to make the first housing 10 and the second housing 20 always have a tendency to rotate in a direction away from each other. Thus, when the latching member 31 moves away from the locking position, the first housing 10 and the second housing 20 can automatically pop open, improving the convenience during use.

[0048] Preferably, the first torsion spring 42 is sleeved on the pin 41, which can ensure both the installation stability of the first torsion spring 42 and the performance of the first torsion spring 42.

[0049] Furthermore, such as Figures 8 to 13As shown, a mounting base 21 is provided on the second housing 20, and the mounting base 21 is provided with a mounting cavity 22. The snap-fit ​​member 31 is slidably disposed in the mounting cavity 22, and the driving member 32 is rotatably connected to the second housing 20 via a rotating shaft. Specifically, in this embodiment, the mounting base 21 is provided with a mounting cavity 22, and the snap-fit ​​member 31 is disposed in the mounting cavity 22. The mounting base 21 can protect the snap-fit ​​member 31, preventing it from being bumped or knocked, thereby ensuring the normal function of the snap-fit ​​member 31.

[0050] Optionally, such as Figures 4 to 7 As shown, the latching member 31 is slidably disposed in the mounting cavity 22, the driving member 32 is rotatably disposed in the second housing 20, one end of the traction member 33 is connected to the latching member 31, and the other end of the traction member 33 is connected to the driving member 32. Specifically, in this embodiment, the traction member 33 is a rope or belt, one end of the traction member 33 is connected to the latching member 31, and the other end of the traction member 33 is connected to the driving member 32. The latching member 31 is rotatably disposed in the second housing 20, and the driving member 32 is rotatably connected to the second housing 20 through a rotating shaft. When the driving member 32 is rotated, the traction member 33 can be wound around the driving member 32, or the length of the traction member 33 wound around the driving member 32 increases, thereby enabling the traction member 33 to drive the latching member 31 away from the locked position. After the latching member 31 releases the latching block 11, the separation of the first housing 10 and the second housing 20 is completed. The transmission is stable and effective, ensuring the convenience of opening the charging box.

[0051] Optionally, in this embodiment, the driving component 32 is a driving wheel. This arrangement facilitates the rotation of the driving component 32 onto the second housing 20. At the same time, the driving wheel reduces the structure of the sharp parts of the charging box, ensuring safety during use and making it convenient for the user.

[0052] Preferably, an anti-slip structure is provided on the outer periphery of the drive wheel, which can increase the friction between the user's hand and the drive wheel, thereby improving the ease of opening the box.

[0053] Alternatively, the anti-slip structure may be an anti-slip pattern or an anti-slip rubber sleeve fitted around the outer circumference of the drive wheel, etc., and there are no restrictions on this.

[0054] Furthermore, such as Figure 9 and Figure 13 As shown, the mounting base 21 is provided with a connecting channel 221, and the mounting cavity 22 is connected to the outside through the connecting channel 221. The snap-fit ​​member 31 includes a guide part 311 and a snap-fit ​​part 312. The snap-fit ​​part 312 is slidably disposed in the connecting channel 221, and the guide part 311 is slidably disposed in the mounting cavity 22.

[0055] Furthermore, such as Figure 9 and Figure 13As shown, the mounting base 21 is provided with a drive channel 222, the mounting cavity 22 is connected to the outside through the drive channel 222, and the traction member 33 passes through the drive channel 222.

[0056] Specifically, in this embodiment, a connecting channel 221 and a driving channel 222 are respectively provided on the two opposite side walls of the mounting base 21. The mounting cavity 22 is connected to the outside through the connecting channel 221 and the driving channel 222. The snap-fit ​​part 312 of the snap-fit ​​member 31 is slidably disposed in the connecting channel 221, thereby snapping into or releasing the snap-fit ​​block 11 to ensure the normal opening and closing of the charging box. The guide part 311 of the snap-fit ​​member 31 is slidably disposed in the mounting cavity 22, and the mounting cavity 22 can guide the guide part 311, thereby... The device can guide the latching component 31, thereby ensuring the stability of the latching component 31's position. When the latching component 31 is in the latching position, the gap between the first housing 10 and the second housing 20 is small, preventing dust from entering the charging box through the gap between the first housing 10 and the second housing 20. The drive channel 222 and the connecting channel 221 are arranged opposite to each other, and the traction member 33 passes through the drive channel 222, which facilitates the traction member 33 to provide power to the latching component 31, thereby ensuring the performance of the latching component 31.

[0057] In one embodiment, the snap-fit ​​mechanism 30 further includes a spring 36 disposed in the mounting cavity 22. One end of the spring 36 is connected to or abuts against the snap-fit ​​member 31, and the other end of the spring 36 is connected to or abuts against the side wall of the mounting cavity 22 away from the snap-fit ​​block 11. Specifically, in this embodiment, both ends of the spring 36 elastically abut against the snap-fit ​​member 31 and the side wall of the mounting cavity 22 away from the snap-fit ​​block 11, respectively. Under the drive of the spring 36, the snap-fit ​​member 31 can snap into the snap-fit ​​block 11, thereby ensuring the connection stability of the first housing 10 and the second housing 20.

[0058] Alternatively, in another embodiment, the two ends of the spring 36 are fixedly connected to the snap-fit ​​member 31 and the side wall of the mounting cavity 22 away from the snap-fit ​​block 11, respectively, which can also achieve the above-mentioned technical effect. No specific limitation is made here.

[0059] Optionally, in another embodiment, a second torsion spring is connected between the driving member 32 and the second housing 20. The second torsion spring is used to reset the driving member 32. Specifically, in this embodiment, the driving member 32 is rotatably connected to the second housing 20 via a rotating shaft. The second torsion spring is sleeved on the rotating shaft and limited by the second housing 20. When the charging case is opened, applying a force to the driving member 32 can drive the driving member 32 to rotate, and at the same time, it will compress the second torsion spring, so that the second torsion spring has a force that can drive the driving member 32 to reset. Therefore, after the force applied to the driving member 32 stops, the restoring force of the second torsion spring can drive the driving member 32 to reset, further ensuring that the latching member 31 can be in the locked position, avoiding the latching member 31 from jamming, thereby ensuring the stability of the charging case when it is closed, effectively preventing the charging case from opening without reason, and thus ensuring the performance of the charging case.

[0060] Furthermore, such as Figures 4 to 7 As shown, the latching mechanism 30 also includes a guide wheel 34, which is rotatably mounted on the second housing 20, and the traction member 33 is wound around the guide wheel 34. Specifically, in this embodiment, the guide wheel 34 is rotatably mounted on the second housing 20, and the guide wheel 34 is located on the path connecting the driving member 32 and the latching member 31 through the traction member 33. The traction member 33 is wound around the guide wheel 34. This arrangement allows the guide wheel 34 to divide the traction member 33 into two straight segments, which can be parallel to each other or at an angle, thus changing the direction of the driving force. This makes the placement of each component of the latching mechanism 30 more flexible, improving the versatility of the latching mechanism 30 and reducing the size of the installation space of the latching mechanism 30, thereby improving the space utilization inside the charging box.

[0061] Alternatively, in another embodiment, a guide wheel 34 is provided in the path through which the drive member 32 and the snap-fit ​​member 31 are connected by the traction member 33. The traction member 33 is wound around the guide wheel 34. A third torsion spring is connected between the guide wheel 34 and the second housing 20. The third torsion spring is used to reset the guide wheel 34. Specifically, the guide wheel 34 is rotatably connected to the support block 23 via a rotating shaft. A torsion spring is sleeved on the outer circumference of the rotating shaft, and the two ends of the third torsion spring are respectively limited by the guide wheel 34 and the support block 23. When a force is applied to the driving member 32, the friction between the traction member 33 and the guide wheel 34 can drive the guide wheel 34 to rotate, and at the same time, it will compress the third torsion spring, so that the third torsion spring generates a force to reset the guide wheel 34. Therefore, after the force applied to the driving member 32 stops, the guide wheel 34 is reset under the action of the restoring force of the third torsion spring, which in turn drives the latching member 31 to reset. This ensures that the latching member 31 is in the locked position, effectively avoiding the risk of jamming of the latching mechanism 30, and thus ensuring good stability when the charging box is fastened, improving its performance.

[0062] Furthermore, such as Figure 5As shown, both the driving member 32 and the guide wheel 34 have guide grooves 35, and the traction member 33 is contained within the guide grooves 35. Specifically, in this embodiment, both the driving wheel and the guide wheel 34 are provided with guide grooves 35, and the traction member 33 is simultaneously contained within the guide grooves 35 of both the driving wheel and the guide wheel 34. This arrangement can improve the stability of the traction member 33 during movement, thereby ensuring the performance of the locking mechanism 30.

[0063] Alternatively, in another embodiment, either the drive member 32 or the guide wheel 34 is provided with a guide groove 35, which is not limited here.

[0064] Furthermore, such as Figure 7 and Figure 11 As shown, the second housing 20 also has a support block 23, a mounting base 21 is fixedly disposed on the support block 23, and a guide wheel 34 is rotatably disposed on the support block 23. Specifically, in this embodiment, the second housing 20 includes a side wall and an upper surface. The support block 23 protrudes from the upper surface of the second housing 20, and the mounting base 21 is fixedly disposed on the support block 23. The support block 23 can improve the stability of the mounting position of the mounting base 21, thereby ensuring the sliding stability of the snap-fit ​​member 31 slidably disposed in the mounting base 21. At the same time, the guide wheel 34 is rotatably disposed on the support block 23, and the support block 23 can also ensure the stability of the guide wheel 34 during rotation, thereby ensuring the normal transmission of power and the reliability of the charging box during opening.

[0065] Alternatively, in another embodiment, the snap-fit ​​mechanism 30 may also be directly disposed on the top of the side wall of the second housing 20 and located in the inner direction of the accommodating space enclosed by the second housing 20, without specific limitations.

[0066] In one embodiment, such as Figure 7 and Figure 11 As shown, the first housing 10 is also provided with an assembly groove 12, and the support block 23 is configured to cooperate with the assembly groove 12. Specifically, in this embodiment, when the charging box is in the snap-fit ​​state, the assembly groove 12 on the first housing 10 and the support block 23 on the second housing 20 are inserted into each other, which can improve the accuracy of the relative position between the first housing 10 and the second housing 20 and improve the aesthetics of the charging box; and this configuration allows the support block 23 to extend to the side wall of the second housing 20, which can ensure the connection stability of the support block 23 and the second housing 20, thereby improving the stability of the snap-fit ​​mechanism 30 during operation and ensuring the performance of the charging box.

[0067] In this embodiment, as Figure 7 and Figure 11As shown, both the latching block 11 and the latching member 31 are provided with inclined surfaces. The inclined surfaces of the latching block 11 and the latching member 31 abut against each other to move the latching member 31 away from the locking position. Specifically, in this embodiment, the inclined surfaces include a first inclined surface 111 and a second inclined surface 313. The first inclined surface 111 is provided on the latching block 11, and the second inclined surface 313 is provided on the latching member 31. The first inclined surface 111 can abut against the second inclined surface 313 to move the latching member 31 away from the locking position. When switching the charging case from the open state to the closed state, the user can apply force to the first housing 10, causing the first housing 10 to rotate relative to the second housing 20. During this process, the first inclined surface 111 of the latching block 11 can abut against the second inclined surface 313 of the latching member 31, and the latching block 11 can push the latching member 31, causing the latching member 31 to move away from the locked position. When the first inclined surface 111 of the latching block 11 and the second inclined surface 313 of the latching member 31 disengage, the latching member 31 returns to its original position under the action of the spring 36, thereby making the latching member 31 and the latching block 11 engage. This setting enables the first housing 10 and the second housing 20 to automatically engage, reducing the difficulty of engaging the first housing 10 and the second housing 20 and improving the convenience during use.

[0068] Optionally, in another embodiment, only one inclined surface is provided, which is provided on the latching block 11 or the latching member 31. When switching the charging case from the open state to the closed state, the user can apply a force to the first housing 10, thereby causing the first housing 10 to rotate relative to the second housing 20. During this process, the latching block 11 and the latching member 31 abut against each other through the inclined surface, so that the latching block 11 can push the latching member 31, causing the latching member 31 to move away from the locked position. When the inclined surface and the latching block 11 or the latching member 31 are disengaged, the latching member 31 returns to its original position under the action of the spring 36, thereby making the latching member 31 and the latching block 11 engage. This setting enables the first housing 10 and the second housing 20 to automatically engage, reducing the difficulty of engaging the first housing 10 and the second housing 20 and improving the convenience during use.

[0069] Specifically, the charging case in this embodiment is suitable for wireless earphones, and the earphone body 200 of the wireless earphones is housed within the inner cavity of the charging case. By incorporating the aforementioned charging case, the wireless earphones achieve a compact, small, and convenient structure, easy opening and closing, and a long service life. Furthermore, the safety of the earphone body 200 housed within the charging case is ensured.

[0070] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
