[0002] With the improvement of people's living standards and the increase of various audio-visual entertainment methods, as well as the gradual popularization of corresponding mobile devices such as smartphones and tablets, headphones have gradually become a necessity in people's lives in order to obtain a better sound experience without disturbing others. Over-ear Bluetooth headphones have gradually become favored by many users because they cause less damage to the ears and have better sound quality. Chinese patent CN210629822U discloses a retractable earphone, including a left earcup, a right earcup, and a U-shaped headband connecting the left and right earcups. The left and right earcups are symmetrically arranged. The left earcup has an elongated slot, and a microphone is hinged to the front of the left earcup. This invention has a simple structure and a clean appearance. It can hide the microphone rod inside the earphone, effectively solving the problem of the microphone rod's visibility to the user, increasing the reliability and durability of the microphone rod's rotation, and enhancing the user experience. Current headphones, due to differences in users' ears, such as variations in auricular rotation angle, and the inability of the earcups to rotate, cannot properly fit users, easily causing discomfort and reducing the applicability of the device. To address this, we propose a Bluetooth headset with rotatable earcups. Summary of the Invention

[0003] The purpose of this invention is to provide a Bluetooth headset with rotatable earcups, in order to solve the problem mentioned in the background art that current headsets cannot rotate during use, cannot fit the user well, easily cause user discomfort, and reduce the applicability of the device.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a Bluetooth headset with rotatable earcups, including a headband, with mounting plates fixed at both ends of the inner sidewall of the headband, earcups connected to one side of the mounting plates, a sponge pad connected to one side of the earcups, a rotating mechanism connected inside the mounting plates, and the earcups connected to one side of the mounting plates via the rotating mechanism, a disassembly mechanism connected to the inner cavity of the earcups, and the sponge pad connected to one side of the earcups via the disassembly mechanism.

[0005] As a further description of the above technical solution: The rotating mechanism includes a rotating shaft that rotates within the inner cavity of the mounting plate. A stop block is fixed to the outer wall of the rotating shaft. A limit groove is formed on the inner wall of the mounting plate. Positioning grooves are evenly formed on the inner wall of the mounting plate. A contraction cavity is formed inside the rotating shaft and extends through the outer side of the rotating shaft. A first strong spring is fixed to the middle of one side of the contraction cavity. A connecting plate is fixed to one end of the first strong spring. A positioning post is fixed to the middle of the bottom of the connecting plate.

[0006] As a further description of the above technical solution: The limiting groove is an arc groove, the stop block is connected inside the limiting groove, and the rotating shaft is fixed to the middle of one side of the earcup.

[0007] As a further description of the above technical solution: The connecting plate slides inside the contraction cavity, the end of the positioning post is a hemispherical surface, and the positioning groove is a hemispherical groove.

[0008] As a further description of the above technical solution: The disassembly and assembly mechanism includes push rods that symmetrically slide through both sides of the inner cavity of the earcup. One end of the push rod is fixed with a connecting plate, a second strong spring is fixed with one side of the connecting plate, insertion rods are symmetrically fixed with one side of the connecting plate, a connecting shell is fixed with one side of the sponge pad, and insertion holes are symmetrically opened through both sides of the connecting shell.

[0009] As a further description of the above technical solution: One end of the second strong spring is fixed to the inner wall of the ear cup, and the second strong spring is sleeved on the outside of the push rod. The two sides of the connecting shell are provided with slots.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This rotatable Bluetooth headset rotates by rotating the earcups, causing the pivot to rotate and the positioning groove to press against the end of the positioning post. This causes the positioning post to retract into the contraction cavity, and the connecting plate to press against the first strong spring. When the positioning post aligns with the next positioning groove, the first strong spring resets the positioning post, embedding it into the positioning groove and fixing the pivot. This fixes the earcups, making it easy to rotate and adjust the angle of the earcups. This allows the earcups to better fit different ear shapes, making the user more comfortable and improving the applicability of the device.

[0011] This rotatable Bluetooth headset allows for easy replacement of damaged or worn-out earpads. By pressing a lever, the connecting plate moves, stretching the second strong spring and disengaging the plug from the socket, thus releasing the connecting shell and allowing the foam pad to be removed. A new foam pad can then be installed, embedding the connecting shell into the earpad. Loosening the lever resets the second strong spring, causing the connecting plate to return the plug to its original position and re-insert it into the socket, completing the fixation. This facilitates the replacement of damaged or worn-out foam pads, improving ease of replacement and enhancing the device's practicality. Attached Figure Description

[0017] This invention provides a Bluetooth headset with rotatable earcups, allowing for easy adjustment of the earcup angle to better fit different ear shapes, resulting in greater user comfort and improved device versatility. Please refer to [link / reference]. Figure 1 It includes a head beam 1, and mounting plates 2 are fixed at both ends of the inner sidewall of the head beam 1; Please refer to it again. Figure 1 One side of the mounting plate 2 is connected to the ear cup 3, and one side of the ear cup 3 is connected to the sponge pad 4. Please refer to it again. Figure 1 and Figure 2 The mounting plate 2 is internally connected to a rotating mechanism 5, and the earcups 3 are connected to one side of the mounting plate 2 via the rotating mechanism 5. The inner cavity of the earcups 3 is connected to a disassembly mechanism 6, and the sponge pad 4 is connected to one side of the earcups 3 via the disassembly mechanism 6.

[0018] Please refer to it again. Figure 3 The rotating mechanism 5 includes a rotating shaft 501 that rotates within the cavity of the mounting plate 2, and a stop block 502 is fixed to the outer wall of the rotating shaft 501. Please refer to it again. Figure 3The inner cavity sidewall of the mounting plate 2 is provided with a limiting groove 503, and the inner cavity sidewall of the mounting plate 2 is provided with positioning grooves 504 evenly. The rotating shaft 501 is provided with a shrinkage cavity 505 inside, and the shrinkage cavity 505 penetrates through the outer side of the rotating shaft 501. Please refer to it again. Figure 3 A first strong spring 506 is fixed in the middle of one side of the contraction cavity 505. A connecting plate 507 is fixed at one end of the first strong spring 506. A positioning post 508 is fixed in the middle of the bottom of the connecting plate 507.

[0019] In summary, by rotating the earcup 3, the rotating shaft 501 is driven to rotate, causing the positioning groove 504 to press against the end of the positioning post 508, thereby causing the positioning post 508 to retract into the shrinkage cavity 505. This causes the connecting plate 507 to press against the first strong spring 506. When the positioning post aligns with the next positioning groove 504 of 508, the first strong spring 506 resets, causing the positioning post 508 to be embedded in the positioning groove 504, fixing the rotating shaft 501, and thus fixing the earcup 3. This facilitates the rotation of the earcup 3, making it easy to adjust the angle of the earcup 3, allowing the earcup 3 to better fit different auricles, making the user more comfortable and improving the applicability of the device.

[0020] Please refer to it again. Figure 2 and Figure 3 The limiting groove 503 is an arc groove, the stop block 502 is connected inside the limiting groove 503, and the rotating shaft 501 is fixed to the middle of one side of the earcup 3.

[0021] Please refer to it again. Figure 3 The connecting plate 507 slides inside the contraction cavity 505, the end of the positioning post 508 is a hemispherical surface, and the positioning groove 504 is a hemispherical groove.

[0022] Please refer to it again. Figure 4 and Figure 5 The disassembly and assembly mechanism 6 includes a push rod 601 that slides symmetrically through both sides of the inner cavity of the ear cup 3. One end of the push rod 601 is fixed with a connecting plate 602. A second strong spring 603 is fixed on one side of the connecting plate 602. A plug rod 604 is symmetrically fixed on one side of the connecting plate 602. A connecting shell 605 is fixed on one side of the sponge pad 4. Plug holes 606 are symmetrically opened on both sides of the connecting shell 605.

[0023] Please refer to it again. Figure 4 and Figure 5 One end of the second strong spring 603 is fixed to the inner cavity side wall of the ear cup 3, and the second strong spring 603 is sleeved on the outside of the push rod 601. The two sides of the connecting shell 605 are provided with slots.

[0024] In summary, by pressing the actuating rod 601, the connecting plate 602 is moved, causing the second strong spring 603 to stretch. Simultaneously, the insertion rod 604 is disengaged from the insertion hole 606, releasing the fixing of the connecting shell 605. This allows the sponge pad 4 to be disassembled, and then a new sponge pad 4 to be installed. The connecting shell 605 is then embedded in the earcup 3. Loosening the actuating rod 601 allows the second strong spring 603 to reset, causing the connecting plate 602 to move the insertion rod 604 back to its original position. The insertion rod 604 is then inserted into the insertion hole 606, completing the fixing process. This facilitates the replacement of damaged or aged sponge pads 4, improving the convenience of replacement and enhancing the practicality of the device.

[0025] In practical use, when the angle of the earcup 3 needs to be adjusted, rotating the earcup 3 drives the rotating shaft 501 to rotate, causing the positioning groove 504 to press against the end of the positioning post 508, thereby causing the positioning post 508 to retract into the shrinkage cavity 505. This causes the connecting plate 507 to press against the first strong spring 506. When the positioning post aligns with the next positioning groove 504 of 508, the first strong spring 506 resets, causing the positioning post 508 to be embedded in the positioning groove 504, fixing the rotating shaft 501, thereby fixing the earcup 3. This facilitates the rotation of the earcup 3 and the adjustment of its angle, allowing the earcup 3 to better fit the body. To accommodate different earlobes, when the foam pad 4 is damaged or aged, press the actuating rod 601 to move the connecting plate 602, causing the second strong spring 603 to stretch. At the same time, the insertion rod 604 is disengaged from the insertion hole 606, releasing the fixing of the connecting shell 605, thereby disassembling the foam pad 4. Then, install the new foam pad 4, so that the connecting shell 605 is embedded in the ear cup 3. Loosen the actuating rod 601, and through the reset of the second strong spring 603, the connecting plate 602 drives the insertion rod 604 to reset, allowing the insertion rod 604 to be inserted into the insertion hole 606 to complete the fixing, thus facilitating the replacement of the damaged or aged foam pad 4.
