[0002] Currently, wireless headphones have become the main trend in the headphone industry. Wireless headphones are usually charged by placing them in a charging case, which also serves as a storage solution.
[0003] Existing charging cases consist of an upper shell and a lower shell, which are connected by a hinge. The upper shell rotates to open and close. Usually, a magnetic or snap-fit structure is set between the upper and lower shells to allow them to fit together properly. However, the magnetic structure can lead to limited stability in the connection between the upper and lower shells. When the charging case is placed with other items, the upper and lower shells can easily separate, resulting in the loss of earphones. On the other hand, the snap-fit structure can deform during opening and closing, and long-term use can cause wear and tear on the snap-fit structure, which in turn affects the stability of the connection between the upper and lower shells of the charging case, thus shortening the lifespan of the charging case.
[0004] Therefore, a charging case and wireless earphones are needed to solve the above problems. Utility Model Content

[0044] like Figures 1 to 13 As shown, this embodiment provides a charging box, which includes a first housing 10 and a second housing 20 rotatably connected. The first housing 10 is provided with a snap-fit block 11, and the second housing 20 is provided with a locking mechanism. The locking mechanism includes a swing rod 22, which is rotatably disposed on the second housing 20. When the swing rod 22 is in the locked position, one end of the swing rod 22 can snap into the snap-fit block 11. When the swing rod 22 is in the unlocked position, one end of the swing rod 22 releases the snap-fit block 11. Specifically, in this embodiment, when in the locked position, one end of the swing arm 22 can engage with the locking block 11, locking the first housing 10 and the second housing 20 in a snap-fit state, ensuring the connection stability of the first housing 10 and the second housing 20. When in the unlocked position, one end of the swing arm 22 releases the locking block 11, thereby allowing the first housing 10 and the second housing 20 to open normally, ensuring the normal use function of the charging box. Moreover, the swing arm 22 and the locking block 11 are engaged in a rotating manner, which has the advantage of reducing component failure and deformation compared to the snap-fit structure in the prior art, thereby extending the service life of the charging box.
[0045] Specifically, in this embodiment, the first shell 10 and the second shell 20 are only used to distinguish between the two shells. The first shell 10 can be an upper shell or a lower shell. When the first shell 10 is an upper shell, the second shell 20 corresponds to the lower shell, and when the first shell 10 is a lower shell, the second shell 20 corresponds to the upper shell. This will not be elaborated further here.
[0046] Furthermore, such as Figure 3 and Figure 6 As shown, the locking mechanism includes a connecting rod 23, and the other end of the swing arm 22 is connected to the connecting rod 23. Specifically, in this embodiment, the connecting rod 23 allows for a flexible adjustment range of the unlocking position of the swing arm 22, thereby improving product versatility and the opening and closing flexibility of the charging case.
[0047] Furthermore, such as Figure 3 and Figure 6As shown, at least two swing arms 22 are provided, each swing arm 22 is equipped with a locking block 11, and at least two swing arms 22 are connected to the connecting rod 23. Specifically, in this embodiment, there are two locking blocks 11 and two swing arms 22. The two swing arms 22 and the two locking blocks 11 can be locked together accordingly. This arrangement can improve the force balance of the first housing 10 and the second housing 20, thereby improving the connection stability of the first housing 10 and the second housing 20 and ensuring the functionality of the charging box.
[0048] Optionally, at least two swing arms 22 are connected to the connecting rod 23. The connecting rod 23 can drive at least two swing arms 22 to rotate synchronously. Only force needs to be applied to the connecting rod 23 to ensure that the charging box can be opened, thus improving the ease of opening the charging box.
[0049] Furthermore, the locking mechanism also includes an actuating element 21, which is fixedly connected to the connecting rod 23. Specifically, in this embodiment, the actuating element 21 is a protrusion fixedly connected to the connecting rod 23. By applying force to the protrusion, the connecting rod 23 can be moved, and the connecting rod 23 drives the swing arm 22 to rotate, thereby ensuring the normal opening of the charging box.
[0050] In another embodiment, the locking mechanism further includes an actuating element 21, which is rotatably connected to the second housing 20 and rotatably connected to the connecting rod 23. Specifically, the actuating element 21 and the swing rod 22 are rotatably connected to the second housing 20, and the connecting rod 23 is rotatably connected to the actuating element 21 and the swing rod 22, respectively. This allows rotating the actuating element 21 to drive the connecting rod 23 to move, thereby transmitting the power of the actuating element 21 to the swing rod 22 and ensuring the functionality of the locking mechanism.
[0051] Optionally, the two rocker arms 22 are rotatably connected to the two ends of the connecting rod 23, and the actuating element 21 is rotatably disposed in the middle of the connecting rod 23. Actuating the actuating element 21 can drive the connecting rod 23 to move, thereby driving the rocker arms 22 located at both ends of the connecting rod 23 to move synchronously, which simplifies the structure and improves the ease of use.
[0052] Furthermore, such as Figure 9 and Figure 10 As shown, the locking mechanism also includes a reset member, which is located at the rotation shaft 31 of the swing arm 22. Specifically, in this embodiment, the reset member enables the swing arm 22 to stop in the locked position, thereby improving the connection stability of the first housing 10 and the second housing 20, ensuring that the first housing 10 and the second housing 20 will not separate from each other during use, and thus ensuring the safety of the charging box.
[0053] Specifically, in this embodiment, the reset component is a torsion spring 30, a rotating seat 25 is provided on the mounting base 24, and the swing arm 22 is rotatably connected to the rotating seat 25 through the rotating shaft 31. The torsion spring 30 is sleeved on the outer periphery of the rotating shaft 31, and one end of the torsion spring 30 is connected to the mounting base 24, and the other end is connected to the swing arm 22. When the swing arm 22 rotates, the torsion spring 30 will be subjected to force and twist, thereby generating an elastic restoring force, so that the torsion spring 30 can always drive the swing arm 22 to stop in the locked position, thereby improving the connection stability of the first shell 10 and the second shell 20 of the charging box.
[0054] Optionally, in this embodiment, when the toggle member 21 is rotatably mounted on the mounting base 24, a reset member is also provided at the rotation shaft 31 of the toggle member 21, which further improves the connection stability of the first housing 10 and the second housing 20.
[0055] Specifically, in this embodiment, torsion springs 30 are provided at the rotation shaft 31 of both the rocker arm 22 and the actuating member 21 to improve safety during use. In another embodiment, torsion springs 30 may be provided only at the rotation shaft 31 of the rocker arm 22, and this is not a limitation.
[0056] In other embodiments, the reset element may also be a tension spring, one end of which is connected to the rocker arm 22 and the other end of which is connected to the first housing 10 or the second housing 20. The tension spring causes the rocker arm 22 to always have a tendency to move to the locked position, and thus also causes the rocker arm 22 to stop in the locked position, thereby ensuring the connection stability of the first housing 10 and the second housing 20.
[0057] Furthermore, such as Figures 1 to 9 as well as Figure 11 and Figure 12As shown, the first housing 10 is provided with an alignment groove 12, and the second housing 20 is provided with a mounting base 24. The rocker arm 22 is rotatably connected to the mounting base 24 via a rotating shaft 31. A snap-fit block 11 is disposed in the alignment groove 12, and the mounting base 24 is provided with a mounting cavity 241. The mounting cavity 241 is connected to the outside through a first channel 242 and a second channel 243, respectively. One end of the rocker arm 22 can extend from the second channel 243 into the alignment groove 12. Specifically, in this embodiment, the alignment groove 12 and the mounting base 24 are correspondingly arranged, so that when the first housing 10 and the second housing 20 are fastened together, a portion of the structure of the mounting base 24 is located in the alignment groove 12, thereby improving the sealing performance between the first housing 10 and the second housing 20. The mounting base 24 is provided with a mounting cavity 241, and the connecting rod 23 is disposed in the mounting cavity 241, thereby improving the movement stability of the connecting rod 23 and effectively avoiding the influence of external structures on the movement of the connecting rod 23. The mounting base 24 can also provide sufficient support for the actuating member 21 and the swing arm 22, thereby improving the movement stability of the locking mechanism. The first channel 242 and the second channel 243 are arranged opposite to each other. The first channel 242 connects the mounting cavity 241 to the outside, allowing one end of the actuating member 21 to extend out from the first channel 242 for easy actuation by personnel. The second channel 243 connects the mounting cavity 241 to the alignment groove 12, allowing one end of the swing arm 22 to extend out from the second channel 243 into the alignment groove 12 and engage with the locking block 11, ensuring the connection stability of the first housing 10 and the second housing 20.
[0058] Specifically, in this embodiment, the hinge joint between the rocker arm 22 and the mounting base 24 and the hinge joint between the actuating member 21 and the mounting base 24 are both located in the second channel 243, which facilitates installation.
[0059] Furthermore, such as Figure 11 and Figure 12 As shown, the latching block 11 has a pressing surface 111, which is inclined. Specifically, in this embodiment, after the first housing 10 and the second housing 20 are opened, the swing rod 22 will stop in the locked position under the action of the reset member. During the process of fastening the first housing 10 and the second housing 20, the inclined pressing surface 111 can gradually press against the swing rod 22, thereby pushing the swing rod 22 from the locked position to the unlocked position. After the swing rod 22 disengages from the pressing surface 111, it can automatically return to the locked position under the action of the reset member. Thus, by applying pressure to the first housing 10 or the second housing 20, the first housing 10 and the second housing 20 can be switched from the open state to the fastened state, avoiding the need to move the actuating member 21 when switching the first housing 10 and the second housing 20 from the open state to the fastened state, thus improving the convenience of use.
[0060] Furthermore, such as Figure 11 and Figure 12As shown, the locking block 11 also has a clearance surface 112, which is angled to the pressing surface 111. Specifically, in this embodiment, since the swing rod 22 is rotatably configured, the part near the hinge and the part away from the hinge have a certain positional difference in the extension direction of the connecting rod 23. The clearance surface 112 can clear the swing rod 22, ensuring its functionality.
[0061] This embodiment also provides a wireless earphone, which includes an earphone body 2 and the aforementioned charging case. The earphone body 2 can be placed in the charging case. By incorporating the charging case, this wireless earphone effectively prevents the first housing 10 and the second housing 20 from detaching, improving the safety of the earphone body 2 during use and preventing its loss. Furthermore, the contact-type snap-fit design extends the lifespan of the charging case, thereby extending the lifespan of the wireless earphone.
