Description

Technical Field

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

[0002] As the core carrier of modern mobile audio devices, Bluetooth earphones rely heavily on their charging cases for portability and battery life. Charging cases not only provide storage and protection for the earphones but also integrate a battery module for charging, while enabling quick and easy access via magnetic or snap-on mechanisms. With in-ear earphones becoming mainstream, the structural design of charging cases must balance earphone protection, charging efficiency, and the storage needs of users' personal accessories, making it a key component affecting user experience.

[0003] In-ear Bluetooth headphones typically come with multiple sets of silicone ear tips in different sizes to fit different ear canals and ensure a secure fit. These ear tips can also serve as spares. If the original ear tips are lost, the spare ear tips can be installed on the headphones to ensure they can still be used. Currently, commercially available charging cases generally lack a dedicated storage design for ear tips. After purchasing in-ear Bluetooth headphones, spare ear tips are usually just placed in the headphone box in a pouch, and users have to keep them safe themselves, as there is no dedicated storage place for spare ear tips. Utility Model Content

[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides a portable Bluetooth headset charging and storage box, which can effectively solve the technical problem of having no place to store spare earplugs.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A portable Bluetooth earphone charging and storage case includes a case body and a lid. The case body contains an inner liner and a charging component. The inner liner is nested within the opening of the case body, and its inner wall, combined with the inner wall of the case body, forms an electronic control cavity. The charging component is housed within this cavity. The surface of the nested inner liner has an earphone storage slot for storing Bluetooth earphones. The inner wall of the lid has a storage cavity containing at least two ear tip storage posts. The total number of ear tip storage posts is even. These posts are used to store spare ear tips for the Bluetooth earphones. The surface of each ear tip storage post has an anti-dislodgement structure, including three or more positioning rings with a semi-circular cross-section. A guide slope is provided at the end of each ear tip storage post away from the lid. A cover plate is located at the opening of the lid and is connected to the lid via a magnetic component. The cover plate is used to close the storage cavity, and its surface has positioning grooves that match the shape of the Bluetooth earphones.

[0007] Furthermore, the charging component includes a main control circuit board, a battery, a charging port, and a power supply point. The battery, charging port, and power supply point are all electrically connected to the main control circuit board. The charging port extends to the surface of the housing, and the power supply point extends to the inner wall of the earphone storage slot.

[0008] Furthermore, the main control circuit board is also electrically connected to an LED indicator light, which extends to the surface of the housing.

[0009] Furthermore, the LED indicator and lampshade are triangular, with any corner of the triangular lampshade facing the box cover, and the edge of the box cover is provided with positioning protrusions for blind touch.

[0010] Furthermore, the magnetic attraction assembly includes a neodymium iron boron magnet disposed on the edge of the cover plate and a magnetic conductive sheet disposed inside the cover. The magnetic attraction force between the neodymium iron boron magnet and the magnetic conductive sheet is 3-5N, and the surface of the magnetic conductive sheet is provided with an anti-rust coating.

[0011] Furthermore, the positioning groove is embedded with a buffer pad, which is made of foamed silicone material and has a compression amount of 20-30% of the original thickness.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting a storage cavity and earplug cap storage pillars on the inner wall of the box lid, the spare earplug cap storage area and the headphone storage slot are integrated into the same box body, avoiding the need to carry an extra earplug case and realizing the function of one box for multiple uses. The number of earplug cap storage pillars is even, which can accommodate the need for independent storage of left and right earplug caps. When taking them out, the corresponding ear can be quickly matched. The positioning ring adopts a semi-circular cross-section design, which forms a surface contact with the inner wall of the earplug cap, and the clamping force is evenly distributed, reducing the earplug cap drop rate and improving stability. The guide slope reduces the resistance to inserting the earplug cap and improves the success rate of one-handed operation. Attached Figure Description

[0017] The following is combined Figures 1-2 The present invention provides a detailed description of a portable Bluetooth headset charging and storage box:

[0018] A portable Bluetooth earphone charging and storage case includes a case body 1 and a case lid 2. The case body 1 contains an inner liner 3 and a charging assembly. The inner liner 3 is nested within the opening of the case body 1. The inner wall of the inner liner 3 and the inner wall of the case body 1 combine to form an electronic control cavity 4. The charging assembly is disposed within the electronic control cavity 4. The surface of the inner liner 3 has an earphone storage slot 5 for storing Bluetooth earphones. The inner wall of the case lid 2 has a storage cavity 6, within which two ear tip storage posts 7 are fixedly installed. The storage column 7 is used to store spare ear tips for Bluetooth earphones. The surface of the ear tip storage column 7 is provided with an anti-dislodgement structure, which includes three positioning rings 8. The cross-section of the positioning rings 8 is semi-circular. The end of the ear tip storage column 7 away from the lid 2 is provided with a guide slope 9. The lid 2 is provided with a cover plate 10 at the snap opening. The cover plate 10 is connected to the lid 2 by a magnetic component. The cover plate 10 is used to close the storage cavity 6. The surface of the cover plate 10 is provided with a positioning groove 11 that matches the shape of the Bluetooth earphone.

[0019] By setting a storage cavity 6 and earplug cap storage pillars 7 on the inner wall of the lid 2, the spare earplug cap storage area and the headphone storage slot 5 are integrated into the same box 1, avoiding the need to carry an extra earplug case and realizing the function of one box for multiple uses. The number of earplug cap storage pillars 7 is even, which can accommodate the need for independent storage of left and right earplug caps. When taking them out, they can be quickly matched with the corresponding ear. The positioning ring 8 adopts a semi-circular cross-section design, which forms a surface contact with the inner wall of the earplug cap, and the clamping force is evenly distributed, reducing the earplug cap drop rate and improving stability. The guide slope 9 reduces the resistance to inserting the earplug cap and improves the success rate of one-handed operation.

[0020] The charging assembly includes a main control circuit board 12, a battery 13, a charging port 14, and a power supply point 15. The battery 13, charging port 14, and power supply point 15 are all electrically connected to the main control circuit board 12. The charging port 14 extends to the surface of the housing 1, and the power supply point 15 extends to the inner wall of the earphone storage slot 5. The main control circuit board 12 is also electrically connected to an LED indicator 16, which extends to the surface of the housing 1. The LED indicator 16 and its lampshade form a triangle, with any corner of the triangular lampshade facing the housing cover 2. The edge of the housing cover 2 is provided with a positioning protrusion 17 for blind operation. The triangular lampshade points towards the housing cover 2. Combined with the positioning protrusion 17 on the edge of the housing cover 2, the opening direction can be quickly identified by touch during blind operation, improving the success rate of operation in dark environments. The LED indicator 16 displays the battery level and charging status in real time, allowing users to understand the device status without opening the cover. The triangular lampshade and the positioning protrusion 17 form a visual-tactile dual-guidance system, enabling users to quickly identify the direction and open the cover when taking the device out of their pocket.

[0021] The magnetic attraction component includes a neodymium iron boron magnet 18 located on the edge of the cover plate 10 and a magnetic conductive sheet 19 located inside the lid 2. The magnetic attraction force between the neodymium iron boron magnet 18 and the magnetic conductive sheet 19 is 5N, which provides moderate opening and closing force with one hand. This not only prevents accidental opening but also allows for easy opening with one finger. Furthermore, the surface of the magnetic conductive sheet 19 is coated with an anti-rust coating, which improves corrosion resistance in humid environments.

[0022] The positioning groove 11 is embedded with a buffer pad 20. The buffer pad 20 is made of foamed silicone material and the compression amount is 20-30% of the original thickness. The combination design of the positioning groove 11 and the buffer pad 20 precisely restricts the displacement of the earphone and avoids wear on the charging contacts.
