Description

Technical Field

[0001] This utility model relates to the field of charging case technology, specifically a wireless charging Bluetooth headset charging case. Background Technology

[0002] With the rapid development of wireless technology, Bluetooth earphones have become an indispensable audio device in people's daily lives, providing users with great convenience. Battery life has always been a major concern for users; therefore, the design and functional optimization of the charging case, as an important accessory for Bluetooth earphones, are particularly important. However, current Bluetooth earphone charging cases on the market have the following design problems:

[0003] First, most charging cases for Bluetooth earphones currently only support wired charging. Users need to manually place the earphones into the charging case and connect them to the charging contacts inside via a physical interface to charge. This wired charging method is not only cumbersome, but frequent plugging and unplugging can easily cause wear and tear on the charging interface, affecting charging efficiency and the durability of the device. In addition, cable management is also a major problem for users. Cables are prone to tangling and knotting, which not only affects aesthetics but may also pose a safety hazard.

[0004] Secondly, the closure between the charging case lid and the bottom box also presents problems. Many charging cases use snap-fit ​​or simple friction closure designs, which are often not secure enough and can easily open due to accidental touches or drops, causing the Bluetooth earphones to fall out or be damaged. This insecure closure not only affects the practicality of the charging case but also reduces user satisfaction and trust in the product. Utility Model Content

[0005] In order to overcome the shortcomings of existing technical solutions, this utility model provides a wireless charging Bluetooth earphone charging case, which can effectively solve the technical problems of current Bluetooth earphone charging cases only being able to perform wired charging and the lid and bottom box not being able to close securely.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A wireless charging Bluetooth earphone charging case includes a bottom box and a cover. The bottom box and one end of the cover are connected by a pivot, allowing the cover to flip along the pivot to form an open or closed structure with the bottom box. A lower inner core is installed inside the bottom box, and an upper inner core is installed inside the cover. The lower and upper inner cores together form two cavities for accommodating the Bluetooth earphones.

[0008] The bottom box contains a control circuit board and an electromagnetic induction coil. The electromagnetic induction coil is located near the bottom of the bottom box, and both ends of the electromagnetic induction coil are connected to the control circuit board. The control circuit board is located below the lower inner core and has several conductive charging terminals connected to it. The end of each charging terminal away from the control circuit board extends through the lower inner core into different cavities for contact with the Bluetooth headset for charging.

[0009] The lower inner core has a lower magnetic block installed inside, and the upper inner core has an upper magnetic block installed inside, corresponding to the lower magnetic block. When the cover and the bottom box are closed, the lower magnetic block and the upper magnetic block are fixed together by magnetic attraction.

[0010] Furthermore, the electromagnetic induction coil has a repeatedly wound structure and is fixed by a preset back plate. The back plate and the control circuit board are together fixed in the bottom box by locking components.

[0011] Furthermore, the bottom box is provided with a support member that supports and fixes to the bottom of the lower inner core. The bottom of the support member is connected to the edge of the control circuit board. A fastening and fixing connecting strap connects the control circuit board and the lower inner core.

[0012] Furthermore, a lithium battery is electrically connected to the control circuit board, and an indicator light connected to the control circuit board is provided on the outside of the base box to display the lithium battery level.

[0013] Furthermore, the bottom of the base box is provided with a flat bottom surface, and the flat bottom surface is provided with an anti-slip layer.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) The charging case has a built-in electromagnetic induction coil, which enables wireless charging of Bluetooth earphones. This eliminates the need for cumbersome plugging and unplugging operations, improves the ease of use, and avoids the problems of interface wear and cable tangling caused by traditional wired charging methods.

[0016] (2) The bottom box and the cover of the charging case are fixed by magnetic attraction, which achieves a stable and convenient closing effect, which not only enhances the structural stability of the charging case, but also prevents damage caused by accidental opening or falling.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figure 1-8 As shown, this utility model provides a wireless charging Bluetooth headset charging case, aiming to provide a compact, convenient device for charging Bluetooth headsets. The charging case mainly includes a base box 1 and a cover 2. The base box 1 and one end of the cover 2 are connected by a pivot 3, allowing the cover 2 to rotate along the pivot 3, thus forming an open or closed structure with the base box 1. A lower inner core 4 is installed inside the base box 1, while an upper inner core 5 is installed inside the cover 2. The lower inner core 4 and the upper inner core 5 together have two cavities 7, which are used to accommodate the Bluetooth headset 6.

[0029] Inside the base box 1, a control circuit board 8 and an electromagnetic induction coil 9 are installed. The electromagnetic induction coil 9 is located near the bottom of the base box 1, and its two ends are electrically connected to the control circuit board 8. The electromagnetic induction coil 9 has a repeatedly wound structure and is fixed by a pre-set back plate 13. The control circuit board 8 is located below the lower inner core 4, and the back plate 13 and the control circuit board 8 are together firmly fixed to the base box 1 by locking components 14 (such as screws or rivets). This structure not only ensures the stability and safety of the electromagnetic induction coil 9, but also helps to improve the efficiency of wireless charging.

[0030] On the control circuit board 8, there are several conductive charging terminals 10 connected. The end of these charging terminals 10 away from the control circuit board 8 passes through the lower inner core 4 and extends into the interior of different cavities 7 so as to achieve contact charging with the Bluetooth headset 6.

[0031] For convenient power supply and storage, a lithium battery 17 is electrically connected to the control circuit board 8, providing power to the entire charging compartment. To help users understand the battery level of the lithium battery 17, an indicator light 18 connected to the control circuit board 8 is provided on the outside of the bottom box 1. The indicator light 18 can display the battery level of the lithium battery 17 in real time, allowing users to charge it in a timely manner.

[0032] A support member 15 is provided inside the base box 1 to support and fix the bottom of the lower inner core 4. The bottom of the support member 15 is connected to the edge of the control circuit board 8. In addition, the control circuit board 8 and the lower inner core 4 are further secured by a fastening connecting strap 16. This structure not only enhances the stability of the entire device, but also helps to improve its service life.

[0033] To enhance the closing stability between the bottom box 1 and the cover 2, a lower magnetic block 11 is installed inside the lower inner core 4, while an upper magnetic block 12 corresponding to the lower magnetic block 11 is installed inside the upper inner core 5. When the cover 2 and the bottom box 1 are closed, the lower magnetic block 11 and the upper magnetic block 12 are attracted by magnetism, thereby ensuring that the two are firmly joined together.

[0034] In addition, a flat bottom surface 19 is provided at the bottom of the base box 1, and an anti-slip layer 20 is provided on the flat bottom surface 19 to prevent slipping. These anti-slip layers 20 not only increase the friction between the base box 1 and the placement surface, preventing the charging case from sliding or tipping over during charging, but also help improve the user experience.

[0035] Compared with traditional technologies, the Bluetooth earphone charging case provided by this technical solution achieves wireless charging of the Bluetooth earphones 6 by incorporating an electromagnetic induction coil 9. This eliminates the need for cumbersome plugging and unplugging operations, improving ease of use and avoiding the problems of interface wear and cable tangling caused by traditional wired charging methods. The bottom box 1 and the cover 2 of the charging case are fixed with magnetic attraction, achieving a stable and convenient closure effect. This not only enhances the structural stability of the charging case but also prevents damage caused by accidental opening or drops.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
