Description

Technical Field

[0001] This utility model relates to the field of Bluetooth headset technology, and in particular to a charging case and Bluetooth headset assembly. Background Technology

[0002] Bluetooth earphones are headphone devices that achieve wireless audio transmission through Bluetooth technology. Bluetooth earphone charging cases are used to store and protect the earphones, and to provide power to extend battery life. To facilitate carrying the charging case and to dissipate static electricity, some charging cases also have an anti-static lanyard structure.

[0003] In existing technology, after the lanyard structure is assembled, additional ribbon cables need to be welded to the connector at the end of the lanyard. Then, the other end of the ribbon cable is connected to the main board through a ribbon cable clip. Finally, the main board is connected to the decorative ring at the charging port to achieve electrostatic conduction of the lanyard. This processing method is not only complex and cumbersome, resulting in low production efficiency, but also requires pre-folding the ribbon cable during processing, which can easily lead to breakage or damage, affecting the anti-static function. In addition, the above processing requires the use of welding and assembly equipment, resulting in high investment costs. Furthermore, connecting the ribbon cable clip is difficult to operate, and static electricity can pass through the main board during the process, increasing the risk of electrostatic discharge.

[0004] Therefore, there is an urgent need for a charging case and Bluetooth earphone assembly to solve the above-mentioned technical problems. Utility Model Content

[0043] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0044] like Figures 1 to 8As shown, this embodiment provides a charging case for accommodating and charging Bluetooth earphones. The charging case also features a lanyard structure, which allows the charging case to be hung on an object such as a backpack for easy carrying and use. Furthermore, the lanyard structure has a static discharge function, preventing damage to the Bluetooth earphones from static electricity generated during prolonged use or in dry environments, thus effectively protecting the earphones.

[0045] The charging case in this embodiment includes a housing 1, within which are housed a battery, a motherboard, a charging management chip, and earphone charging contacts (not shown in the figure), enabling functions such as storage, charging, and intelligent control. A charging port 11 is provided on one side of the housing 1 to facilitate charging of the battery within the charging case by an external charging device. A decorative ring 2 is fixedly installed at the charging port 11, enhancing the aesthetics and premium feel of the charging case. Specifically, the decorative ring 2 is made of conductive metal and is electrically connected to the motherboard. A lanyard structure is provided on the housing 1, comprising a lanyard connector 3 and a lanyard. The lanyard connector 3 is fixedly connected to one side wall of the housing 1, and the lanyard is connected to the lanyard connector 3. In this embodiment, the lanyard connector 3 is made of conductive metal, and the lanyard is made of a material with anti-static properties, such as conductive fiber, metal fiber, silver-plated fiber, conductive acrylic fiber, or glass fiber. The housing 1 also includes a conductive spring 4, which is made of a flexible metal material. Both ends of the conductive spring 4 are electrically connected to the lanyard connector 3 and the decorative ring 2, respectively. This enables electrical conductivity between the mainboard, decorative ring 2, conductive spring 4, lanyard connector 3, and lanyard, thereby discharging static electricity from the charging compartment. Optionally, in this embodiment, the conductive spring 4 is made of beryllium copper (BeCu). Beryllium copper not only has high conductivity, meeting the requirements for static electricity conduction, but also high elasticity and hardness, making it resistant to deformation over long-term use. Furthermore, in this embodiment, the conductive spring 4 is integrally formed with the housing 1 through injection molding. After injection molding, the main body of the conductive spring 4 is completely embedded in the side wall of the housing 1, while the two ends of the conductive spring 4 are exposed on the inner wall of the housing 1. Since the conductive spring 4 has a certain elasticity, under the action of elastic force, one end of the conductive spring 4 abuts against the hanging rope connector 3 to achieve electrical conduction with the hanging rope connector 3, and the other end of the conductive spring 4 abuts against the decorative ring 2 to achieve electrical conduction with the decorative ring 2.

[0046] The aforementioned charging case design eliminates the need for pre-folding, welding, and connecting cable clips, simplifying the production process, improving efficiency, and reducing labor and equipment costs. Furthermore, by integrally injection molding the conductive spring 4 with the housing 1, the connection reliability and structural strength are improved, increasing the tensile strength and durability of the conductive spring 4, thus enhancing product quality. Moreover, with one end of the conductive spring 4 electrically contacting the lanyard connector 3 and the other end electrically contacting the decorative ring 2, its conductivity is stable, ensuring excellent electrostatic protection and effectively protecting the Bluetooth headset from static electricity. In addition, integrating the conductive spring 4 into the housing 1 itself results in a more compact structure, saving internal space and facilitating product miniaturization.

[0047] Optionally, in this embodiment, the decorative ring 2 and the lanyard connector 3 are respectively disposed on adjacent sides of the housing 1, thus the conductive spring 4 is configured in a curved shape to facilitate the connection between the decorative ring 2 and the lanyard connector 3. Specifically, one end of the conductive spring 4 is provided with a raised first contact 41, and the other end is provided with a raised second contact 42. The first contact 41 is elastically pressed against the lanyard connector 3 to achieve electrical conduction, and the second contact 42 is elastically pressed against the decorative ring 2 to achieve electrical conduction. In this embodiment, by elastically pressing the first contact 41 onto the lanyard connector 3 and the second contact 42 onto the decorative ring 2, the contact reliability between the two ends of the conductive spring 4 and the lanyard connector 3 and the decorative ring 2 is improved, ensuring a low-impedance, high-stability electrical connection and avoiding short-circuit problems; moreover, the assembly process of the conductive spring 4 with the lanyard connector 3 and the decorative ring 2 is convenient and simplifies the processing flow.

[0048] Furthermore, multiple anchoring holes 43 are provided on both sides of the conductive spring 4. The anchoring holes 43 are configured to cooperate with the ejector pins on the injection mold for positioning during injection molding. This prevents the conductive spring 4 from deviating during injection molding and improves the injection molding accuracy between the conductive spring 4 and the housing 1. In addition, after injection molding, plastic nails can be formed in the anchoring holes 43, thereby achieving mechanical locking between the conductive spring 4 and the housing 1, further increasing the connection between the conductive spring 4 and the housing 1 and preventing the conductive spring 4 from falling off. Optionally, the anchoring hole 43 is a semi-cylindrical notch penetrating the side of the conductive spring 4 to facilitate positioning operations. In this embodiment, the cross-section of the conductive spring 4 is rectangular and should not be too thick or too thin. If it is too thick, the connection between the conductive spring 4 and the housing 1 will be affected due to insufficient plastic coating during injection molding. If it is too thin, the conductive spring 4 will be prone to wobbling due to partial melting during injection molding, thus affecting the positioning effect with the mold. Preferably, in this embodiment, the conductive spring 4 has a width of 0.4 mm and a thickness of 0.2 mm, which is suitable in thickness, has good elasticity, reliable connection, and accurate positioning.

[0049] To connect the lanyard connector 3 to the housing 1, the existing technology typically involves first fixing the lanyard connector 3 in a specific fixture, then applying adhesive to the lanyard connector 3 using a dispensing machine, and finally assembling the lanyard connector 3 onto the housing 1. This process is problematic because the amount of adhesive applied is small and difficult to control, leading to adhesive overflow and contamination of the housing 1 surface. This necessitates additional cleaning steps, reducing production efficiency. Furthermore, the dimensional tolerances between the lanyard connector 3 and the housing 1 result in noticeable height discrepancies and visible gaps after bonding, leading to a poor feel and a cheap appearance. Additionally, to prevent detachment, the contact area between the lanyard connector 3 and the housing 1 needs to be increased, resulting in a larger lanyard connector 3. Moreover, the dispensing and curing processes require time, increasing the production cycle time and reducing efficiency, hindering large-scale, high-efficiency production.

[0050] To address the aforementioned issues, in this embodiment, the lanyard connector 3 is integrally injection molded with the housing 1 as an insert. This design makes the connection between the lanyard connector 3 and the housing 1 more reliable and structurally stronger. The mechanical insert's covering strength is far superior to adhesive bonding, significantly enhancing tensile strength and effectively reducing the risk of the lanyard connector 3 detaching. Furthermore, the injection molding process can be automated at high speed, eliminating the waiting time for dispensing and curing, resulting in higher production efficiency, better product consistency, and improved yield. Moreover, the lanyard connector 3 and the housing 1 are seamlessly integrated, without any steps or gaps, with a smooth surface transition, significantly improving aesthetics and product quality. In addition, the integral injection molding method allows for greater design freedom for the charging compartment; the fixing position of the lanyard connector 3 can be designed in any area of ​​the housing 1, no longer limited to a flat surface, and can also be a curved surface or a complex structure.

[0051] Optionally, the lanyard connector 3 in this embodiment is provided with a first positioning structure, which is configured to cooperate with a second positioning structure on the injection mold for positioning during injection molding. Specifically, the first positioning structure can be a positioning hole 31, and the second positioning structure can be a positioning post. Through the insertion and cooperation of the positioning hole 31 and the positioning post, the lanyard connector 3 is accurately positioned in the injection mold, improving the quality of the injection molded product. Furthermore, the lanyard connector 3 is also provided with a first anti-mistake structure, which is configured to cooperate with the second anti-mistake structure on the injection mold to prevent mistakes during injection molding. Specifically, the first anti-mistake structure can be an anti-mistake hole 32, the size of which is different from that of the positioning hole 31 (e.g., the diameter of the anti-mistake hole 32 is larger than that of the positioning hole 31), thus effectively preventing the lanyard connector 3 from being installed backwards in the injection mold. It should be noted that the above-mentioned positioning structure and anti-mistake structure can also adopt other structural forms, and are not limited to this embodiment.

[0052] Furthermore, the rope connector 3 is also equipped with an anchoring structure. This anchoring structure surrounds the outer periphery of the rope connector 3, thus providing a circumferential anchoring effect. This enhances the gripping force of the injection-molded body on the rope connector 3, improves connection stability, prevents the rope connector 3 from detaching, and extends the service life of the rope structure. Specifically, such as... Figure 7 As shown, the anchoring structure can be a continuous annular groove 33 surrounding the outer periphery of the rope connector 3, which is simple in structure and easy to manufacture; or, as shown... Figure 8 As shown, the anchoring structure can also include multiple independently set grooves 34, which are distributed at intervals around the outer periphery of the hanging rope connector 3. This structure has better anchoring performance and effectively improves connection stability.

[0053] In some embodiments, the lanyard connector 3 and the housing 1 can also be configured as separate structures. Specifically, the housing 1 has an installation opening 12, and the lanyard connector 3 includes a hook portion 35 and a skirt portion 36 surrounding the hook portion 35. At least a portion of the hook portion 35 is installed in the installation opening 12, and the skirt portion 36 abuts against the inner wall of the housing 1 to prevent the lanyard connector 3 from falling off from the installation opening 12. The hook portion 35 and the skirt portion 36 can be fixed to the housing 1 by means of adhesive or other methods. The hook portion 35 is provided with a lanyard hole 351, and the lanyard is threaded and fixed in the lanyard hole 351.

[0054] Furthermore, in some embodiments, such as Figure 7 As shown, the lanyard connector 3 may be provided with an extension 37 to increase the reliability of its connection with the housing 1. In other embodiments, such as Figure 8 As shown, the lanyard connector 3 may also omit the extension 37 to reduce the size of the lanyard connector 3 and save space.

[0055] This embodiment also provides a Bluetooth headset assembly, including the aforementioned charging case and a Bluetooth headset adapted to the charging case. The charging case is used to store and charge the Bluetooth headset. The Bluetooth headset assembly of this embodiment has a compact structure, reliable connection, high production efficiency, stable electrical conductivity, and effectively improves electrostatic protection.
