DETAILED DESCRIPTION OF THE EMBODIMENTS
[0011] The following further describes in detail the embodiments of the present invention with reference to the drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.
[0012] Please refer to Figures 1-6 , the present invention provides a portable foldable over-ear Bluetooth headset, including two headphone sleeve rods 31, which are hinged between the two headphone sleeve rods 31. This hinged structure enables the headphone sleeve rods 31 to be flexibly folded, facilitating storage and carrying. When not in use, the occupied space of the headphones can be significantly reduced, making it convenient to put them into a backpack, pocket, etc.
[0013] At the lower ends of both headphone sleeve rods 31, there are provided Bluetooth headphone main bodies 32, which are the core components for sound production and signal reception, providing users with high-quality audio experiences. At the front and rear ends of both Bluetooth headphone main bodies 32, there are provided pin slots 33, which cooperate with the disassembly and assembly mechanism to achieve a stable and convenient connection between the Bluetooth headphone main body 32 and the headphone ring sleeve 17.
[0014] At the lower ends of both headphone sleeve rods 31, there are provided a flipping mechanism and a disassembly and assembly mechanism. The flipping mechanism includes a fixing block 11, which is fixedly installed at the lower end of the headphone sleeve rod 31, playing a role in stable support and connection. The lower end of the fixing block 11 is hinged with a headphone ring sleeve 17, enabling the headphone ring sleeve 17 to rotate relative to the fixing block 11, providing the possibility for adjusting the wearing angle. Users can flexibly adjust the position of the headphone ring sleeve 17 according to their own head shape and wearing habits, improving the wearing comfort.
[0015] Two guiding rods 12 are fixedly installed on the fixing block 11. A rectangular locking plate 14 is sleeved on the two guiding rods 12. Two rectangular sliding grooves 13 are provided on the rectangular locking plate 14. The rectangular locking plate 14 is slidably installed on the circumferential surfaces of the two guiding rods 12 through the two rectangular sliding grooves 13 provided. This structural design ensures the stability and accuracy of the sliding of the rectangular locking plate 14 on the guiding rods 12. An L-shaped fixing plate 16 is fixedly installed on the headphone ring sleeve 17. A locking screw rod 15 is threadedly connected to the L-shaped fixing plate 16. The locking screw rod 15 is attached to the surface of the rectangular locking plate 14. When it is necessary to adjust the angle of the headphone ring sleeve 17, rotate the locking screw rod 15 to separate it from the rectangular locking plate 14. The rectangular locking plate 14 can slide on the guiding rods 12, thereby realizing the rotation of the headphone ring sleeve 17. After adjusting the angle, rotate the locking screw rod 15 in the reverse direction to make it fit the rectangular locking plate 14 again, and the position of the headphone ring sleeve 17 can be fixed. The operation is simple and convenient, and can effectively meet the personalized needs of different users.
[0016] A magnetic attraction block 18 is fixedly installed on the headphone ring sleeve 17. When the headphones are folded and stored, the magnetic attraction blocks 18 on the two headphone ring sleeves 17 attract each other, keeping the folded headphones in a compact state, avoiding looseness, further enhancing the convenience and stability of storage, and preventing the headphones from accidentally unfolding during the carrying process.
[0017] The disassembly and assembly mechanism includes a fixed circular ring 21. A circular sliding groove 19 is provided on the earphone ring sleeve 17. The fixed circular ring 21 is fixedly installed in the circular sliding groove 19 opened on the earphone ring sleeve 17, providing a stable track for the sliding of the bolt rod 22. The bolt rod 22 is slidably installed through the fixed circular ring 21. A sliding ring sleeve 24 is fixedly installed on the bolt rod 22. The sliding ring sleeve 24 is slidably installed in the circular sliding groove 19 opened on the earphone ring sleeve 17. A return spring 23 is sleeved on the bolt rod 22. The return spring 23 is fixedly installed between the sliding ring sleeve 24 and the fixed circular ring 21. The bolt rod 22 is inserted into a bolt slot 33 opened on the Bluetooth earphone main body 32. When it is necessary to disassemble the Bluetooth earphone main body 32, the bolt rod 22 is pulled. The bolt rod 22 slides in the circular sliding groove 19 against the elastic force of the return spring 23, so that the bolt rod 22 is disengaged from the bolt slot 33, and thus the Bluetooth earphone main body 32 can be easily removed, facilitating separate cleaning, maintenance or replacement thereof; during installation, just align the Bluetooth earphone main body 32 with the earphone ring sleeve 17 and release the bolt rod 22. Under the action of the elastic force of the return spring 23, the bolt rod 22 automatically inserts into the bolt slot 33, realizing fast and stable installation and ensuring the reliability during the use of the earphone.
[0018] Working principle: First step, in daily use scenarios, when it is necessary to store this portable foldable head-mounted Bluetooth earphone, or when it is necessary to disassemble it for maintenance, replacement of components, etc., the user only needs to pinch the bolt rod 22 on the earphone ring sleeve 17 with a finger and pull it outwards. At this time, the bolt rod 22 will slide in the fixed circular ring 21 along the circular sliding groove 19 against the elastic force of the return spring 23, and the sliding ring sleeve 24 will move in the circular sliding groove 19 accordingly. The end of the bolt rod 22 gradually moves out of the bolt slot 33 opened on the Bluetooth earphone main body 32. When the bolt rod 22 is completely disengaged from the bolt slot 33, the Bluetooth earphone main body 32 can be easily taken out of the earphone ring sleeve 17. Since the structures at the lower ends of the two earphone sleeve rods 31 are the same, both Bluetooth earphone main bodies 32 can be disassembled in this way.
[0019] Step 2. After the disassembly of the main body 32 of the Bluetooth headset is completed, since the tops of the two earphone sleeve rods 31 are hinged, the user can fold the two earphone sleeve rods 31 in half to initially reduce the volume of the earphone. Then, rotate the locking screw 15 on the L-shaped fixing plate 16 of the earphone ring sleeve 17. Since the locking screw 15 is threadedly connected to the L-shaped fixing plate 16, during the rotation, the locking screw 15 will gradually separate from the rectangular lock plate 14 attached to its surface. Subsequently, push the rectangular lock plate 14 upward. Since the rectangular lock plate 14 is slidably installed on the circumferential surfaces of the two guide rods 12 through two rectangular chutes 13 opened, under the limiting action of the guide rods 12, the rectangular lock plate 14 can move upward smoothly and parallelly until it is completely removed from the L-shaped fixing plate 16. At this time, using the hinge structure between the fixing block 11 and the earphone ring sleeve 17, fold the earphone ring sleeve 17 in half. Similarly, the earphone ring sleeve 17 on the other side can also be folded in half in the same operation manner. In this way, the earphone sleeve rods 31 and the earphone ring sleeves 17 are folded into a long strip shape, and the magnetic attraction blocks 18 provided on the two earphone ring sleeves 17 will attract each other, thereby firmly fixing the folded overall structure together, which is convenient for storage and carrying.
[0020] Step 3. When the earphone needs to be used again, first perform the installation operation. Align the fixing block 11 with the earphone ring sleeve 17, and then move the rectangular lock plate 14 downward along the guide rods 12 in the reverse direction so that it is inserted into the L-shaped fixing plate 16. After that, rotate the locking screw 15. As the thread between the locking screw 15 and the L-shaped fixing plate 16 rotates, the locking screw 15 gradually approaches the rectangular lock plate 14 and finally fits tightly, thereby locking the rectangular lock plate 14. At this time, the earphone ring sleeve 17 and the fixing block 11 are firmly fixed together.
[0021] Step 4. After the fixing of the earphone ring sleeve 17 and the fixing block 11 is completed, place the main body 32 of the Bluetooth headset into the earphone ring sleeve 17, adjust the position, and then pull the pin rods 22 at the front and rear ends of the earphone ring sleeve 17 respectively, so that the pin rods 22 compress the return spring 23 and slide in the circular chute 19. After aligning the two pin rods 22 with the pin slots 33 opened on the main body 32 of the Bluetooth headset and releasing them, at this time, under the elastic force of the return spring 23, the pin rods 22 will quickly insert into the pin slots 33, realizing the reliable connection between the main body 32 of the Bluetooth headset and the earphone ring sleeve 17. Thus, the installation of the entire earphone is completed and it can be used normally.
[0022] In the present invention, by providing a hinged structure passing through the earphone sleeve rods 31 and a flip mechanism (including a fixing block 11, an earphone ring sleeve 17, a guide rod 12, a rectangular locking plate 14, an L-shaped fixing plate 16 and a locking screw 15), the earphone can be flexibly folded, the two earphone sleeve rods 31 can be folded along the hinge point, and the earphone ring sleeve 17 can also be rotated on the fixing block 11 and folded, which greatly reduces the storage volume. In addition, the magnetic blocks 18 on the earphone ring sleeve 17 attract each other after folding, so that the earphones remain compact, which is convenient for users to put them. The Bluetooth headset body 32 can be easily removed and installed by putting it into a pocket, backpack, etc., and the portability of the headset is improved, meeting the needs of people to store and carry it at any time in travel, office, etc. In the present invention, the disassembly and assembly mechanism (including the fixed ring 21, the circular slide groove 19, the latch rod 22, the sliding ring sleeve 24, the reset spring 23 and the latch groove 33) is set, so that the Bluetooth headset body 32 can be easily disassembled and installed. When the Bluetooth headset body 32 needs to be cleaned or repaired, the latch rod 22 can be pulled out of the latch groove 33 to be easily removed; when installing, the latch rod 22 is released to reset the latch rod 22. Under the action of the spring 23, the pin slot 33 can be quickly inserted to achieve fixation, which is simple to operate, reduces the difficulty of maintenance, and prolongs the service life of the earphone. In the present invention, through the coordinated work of the fixing block 11, the guide rod 12, the rectangular locking plate 14, the L-shaped fixing plate 16 and the locking screw 15 in the flip mechanism, the user can loosen the locking screw 15 and adjust the angle of the earphone ring sleeve 17 according to his own head shape and wearing habits, and then tighten the locking screw 15 to fix it, which effectively improves the wearing comfort, adapts to the personalized needs of different users, and makes the user not easy to feel tired when using the earphone for a long time. In the present invention, in the disassembly and assembly mechanism, the pin rod 22 slides in the circular slide groove 19 through the sliding ring sleeve 24, and the reset spring 23 provides a stable elastic force, so that the pin rod 22 can be firmly inserted into the pin slot 33, ensuring the stability of the connection between the Bluetooth earphone main body 32 and the earphone ring sleeve 17. During use, even if the earphone is subjected to a certain shaking or collision, the Bluetooth earphone main body 32 is not easy to loosen or fall off, ensuring the normal use of the earphone and improving the user experience.
