[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Reference Figure 1 、 Figure 2 The present invention provides an embodiment of a wireless earhook for conveniently charging Bluetooth headsets. The earhook comprises a housing 1 made of polycarbonate. Polycarbonate has high strength and toughness, and can withstand a certain degree of external impact without cracking or damage, providing reliable protection for the internal electronic components. It also has excellent corrosion resistance, resisting common environmental factors such as sweat and moisture, ensuring that the housing 1 maintains stable performance during long-term use. The front of the housing 1 is detachably connected to a housing 2, also made of polycarbonate. This allows the user to easily remove and install the housing 2 as needed, facilitating maintenance and repair of the internal electronic components. An earhook 3 is fixedly connected to the bottom of the housing 1. The earhook 3 is made of silicone. Silicone is soft and comfortable to wear, preventing pressure on the ear. Silicone also has excellent anti-slip properties, ensuring that the wireless earhook 3 remains firmly fixed to the ear during wear and prevents it from slipping off. The ear hook 3 is C-shaped, which better conforms to the contours of the ear, increasing wearing stability and comfort. The C-shape allows the ear hook 3 to wrap around the back and sides of the ear, providing firm support. Even during exercise or activities, the wireless ear hook 3 can remain stable.

[0028] Reference Figure 2 、 Figure 3 、 Figure 5A plug 4 is fixedly connected to the top of the earhook 3. This plug 4 can be used to connect to an external power source or charging device to provide power to the wireless earhook 3. The plug 4 should be designed for compatibility and stability, ensuring reliable connection with various power sources and charging devices. A magnetic retaining magnet 5 is mounted on the inner rear wall of the housing 1. This magnet 5 has a strong magnetic force. When the Bluetooth headset needs to be charged, it can be placed on the back side of the housing 1. The magnetic retaining magnet 5 will quickly attract the headset, ensuring that the headset remains in a stable position during charging. A receiving coil 6 is also fixedly connected to the inner rear wall of the housing 1. The receiving coil 6 is a key component of wireless charging. It receives external wireless charging signals and converts them into current, providing the energy required to charge the Bluetooth headset. The performance of the receiving coil 6 directly affects the charging efficiency and stability of the wireless earhook 3. A wireless charging receiver motherboard 7 is mounted on the inner wall of the housing 1. This motherboard is responsible for processing and converting the wireless charging signals received by the receiving coil 6, converting them into the current and voltage suitable for charging the Bluetooth headset. The wireless charging receiving motherboard 7 should have high charging conversion efficiency and stable performance to ensure that the Bluetooth headset can be charged quickly and safely.

[0029] Reference Figures 4 to 6 , multiple inner cavities 8 are provided at the four corners of the interior of the shell 1. The inner walls on the front and rear sides of the inner cavity 8 are fixedly connected with fixed rods 9, which provide stable support for the movement of other components. The inner wall of the inner cavity 8 is rotatably connected with a rotating rod 10, and the outside of the rotating rod 10 is fixedly connected with a handle 11. The user can rotate the rotating rod 10 by turning the handle 11. The internal thread of the rotating rod 10 is connected to a threaded column 12. When the rotating rod 10 rotates, the threaded column 12 will move under the action of the thread. Multiple balls 13 are fixedly connected to the adjacent sides of the multiple threaded columns 12. The function of the balls 13 is to cooperate with the clamping plate 14 on the shell 2 2 to achieve a firm connection between the shell 1 and the shell 2 2.

[0030] A snap-on plate 14 is fixedly connected to the rear side of the second housing 2, and a sealing gasket 15 is fixedly connected to the rear side of the snap-on plate 14. The sealing gasket 15 is made of a soft material. When the first and second housings 1 and 2 are connected together, the sealing gasket 15 fits tightly against the front side of the first housing 1, providing a good seal and preventing external factors such as dust and moisture from entering the wireless earhook 3, thereby protecting the internal electronic components. The interior of the snap-on plate 14 is provided with multiple grooves 16. The exterior of the ball 13 engages with the inner walls of the grooves 16, achieving a secure connection between the first and second housings 1 and 2. The exterior of the fixing rod 9 slides inside the threaded post 12, ensuring the stability and linearity of the threaded post 12 during movement. The exterior of the ball 13 slides against the inner wall of the inner cavity 8, allowing the ball 13 to move freely within a certain range to better engage with the grooves 16. When it is necessary to remove the second housing 2 , the user only needs to reversely rotate the handle 11 so that the threaded column 12 drives the ball 13 out of the groove 16 , and the second housing 2 can be easily removed from the first housing 1 .

[0031] Working principle: When the wireless ear hook 3 needs to charge the Bluetooth headset, the Bluetooth headset is placed on the back side of the housing 1, close to the magnetic fixing magnet 5. The magnetic fixing magnet 5 will generate a strong magnetic force to firmly adsorb the Bluetooth headset on the housing of the wireless ear hook 3, ensuring that the position of the headset is stable during the charging process. At this time, the wireless charging receiving motherboard 7 starts working. It receives the external wireless charging signal through the receiving coil 6. The receiving coil 6 is usually made of conductive material such as a copper coil. It can efficiently sense the external electromagnetic field and convert it into current. After the wireless charging receiving motherboard 7 receives the current transmitted by the receiving coil 6, it will process and convert it. It converts the wireless charging signal into a current and voltage suitable for charging the Bluetooth headset. Since the wireless ear hook 3 adopts wireless charging and has no metal contact points, there will be no poor contact problems such as oxidation. At the same time, its radio transmission range can reach within 3mm, which can ensure stable charging power for the Bluetooth headset at close range.

[0032] When installing or sealing the second housing 2, the user rotates the handle 11, causing the handle 11 to rotate the rotating rod 10, which in turn drives the threaded column 12 to move, thereby causing the threaded column 12 to move the ball 13, aligning the second housing 2 with the first housing 1. The user then rotates the handle 11 again, causing the handle 11 to rotate the rotating rod 10, which in turn drives the threaded column 12 to move, thereby causing the threaded column 12 to move the ball 13. When the ear hook 3 needs to be cleaned, the user can easily disassemble the first housing 1 and the second housing 2, thoroughly cleaning the interior of the ear hook 3, ensuring that the ear hook 3 is always clean and tidy. If the ear hook 3 malfunctions and requires repair, the detachable design makes it easier for maintenance personnel to inspect and replace parts, improving maintenance efficiency. Furthermore, the detachable ear hook 3 makes storage and carrying more convenient. When the ear hook 3 is not in use, the user can disassemble it and store it properly, which takes up less space; when carrying the ear hook 3 for travel, the user can also disassemble it as needed, making it easier to put it in a bag or pocket.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
