Description

Technical Field

[0001] This utility model relates to the field of headphone technology, and in particular to a fully concealed, detachable inner headband. Background Technology

[0002] With the widespread use of headphones in entertainment, office, and other scenarios, users' demands for headband comfort, aesthetic appeal, and personalization are constantly increasing. As a core support component of headphones, the headband not only needs to provide a secure fit during wear but also needs to accommodate the different installation requirements of passive and electronic earcups. Especially for electronic earcups, the concealment of the wiring directly affects the overall aesthetics. Furthermore, users desire adjustable headband linings to suit their preferences. Therefore, developing a fully concealed, detachable headband with a removable lining has become a key direction for improving the user experience and competitiveness of headphones.

[0003] Most existing headbands for headphones are made of one-piece injection molding or metal frame splicing structure. Their inner lining is usually glued to the inside of the headband with strong glue or stitching. The earcups are usually locked directly to the brackets at both ends of the headband by fixing bolts. Some headbands with adjustment function rely on simple metal springs or sliding grooves to achieve length adjustment.

[0004] The inner lining of existing headbands is fixed by adhesive or stitching. When users want to change the inner lining to different colors or styles to meet their personalized needs, or when the inner lining is worn or dirty and needs maintenance, the inner lining cannot be removed separately. The entire headband must be disassembled, or even replaced with a completely new headband. This is extremely inconvenient and also results in a fixed and monotonous headband style that is difficult to adapt to diverse user preferences. This reduces the product's flexibility and user experience. Therefore, a fully concealed, detachable inner lining headband is proposed to solve the above problems. Utility Model Content

[0036] Reference Figure 1 - Figure 7 This utility model provides an embodiment of a fully concealed, detachable inner headband, comprising a headband 1. The headband 1 serves as a supporting frame for the overall structure, providing an installation reference for each component and ensuring the overall structural stability of the headband 1. Earmuffs 3 are installed inside the headband 1. The earmuffs 3 are the core components that contact the ears, used to wrap the ears to achieve an acoustic seal and provide wearing comfort. Connecting posts 10 are fixedly connected to the side walls of the earmuffs 3, connecting the earmuffs 3 to the connecting piece 5, transmitting the installation positioning force of the earmuffs 3, and ensuring the connection stability between the earmuffs 3 and the headband 1. A spring rod 4 is fixedly connected inside the headband 1. The spring rod 4 has elastic deformation capability and can be adjusted according to the user's... The headband 1 is designed to automatically adjust the distance between its two ends to improve the fit when worn. Both ends of the spring rod 4 are fixedly connected to connectors 5. Connectors 5 serve as the intermediate connecting parts between the spring rod 4 and the connecting post 10, enabling indirect connection between the earmuff 3 and the spring rod 4 while ensuring effective force transmission. Connectors 5 are fitted onto the outer wall of the connecting post 10. The top of the headband 1 is slidably connected to an inner liner 2. The inner liner 2 is in direct contact with the user's head, providing cushioning and pressure relief, reducing the pressure on the head during prolonged wear, and improving wearing comfort. The inner liner 2 has a buckle assembly inside, which enables the detachable connection between the inner liner 2 and the headband 1, facilitating the removal and replacement of the inner liner 2.

[0037] The snap-fit ​​assembly includes a snap-fit ​​plate 6, which serves as the supporting base for the snap-fit ​​assembly, provides space for the snap-fit ​​groove 7, and transmits the installation force of the inner bushing 2. The top of the snap-fit ​​plate 6 is fixedly connected to the bottom of the inner bushing 2. The snap-fit ​​groove 7 is provided inside the snap-fit ​​plate 6, which is used to cooperate with the snap-fit ​​pin 9 to form an engaging structure, realizing the positioning connection between the inner bushing 2 and the snap-fit ​​block 8. The top of the headband 1 is fixedly connected to the snap-fit ​​block 8, which provides a fixed support point for the snap-fit ​​pin 9 and is the connection carrier between the snap-fit ​​assembly and the headband 1. The snap-fit ​​pin 9 is fixedly connected to the side wall of the snap-fit ​​block 8, and the snap-fit ​​pin 9 engages with the snap-fit ​​groove 7, which can directly lock the relative position of the inner bushing 2 and the headband 1, preventing the inner bushing 2 from sliding and shifting during use. The connecting column 10 is provided with a limit component to limit... The positioning component is used to limit the relative movement between the connecting post 10 and the connector 5, preventing the connecting post 10 from detaching from the connector 5 and ensuring the installation stability of the earmuff 3. A support block 11 is fixedly connected to the side wall of the connector 5. The support block 11 provides installation support for the hollow post 12, ensuring that the position of the hollow post 12 is fixed. The hollow post 12 is fixedly connected inside the support block 11. The hollow post 12 provides a closed installation space for the locking component, ensuring the structural stability of the locking component and its normal function. The locking component is set inside the hollow post 12. The locking component and the limiting component work together to further strengthen the connection between the connecting post 10 and the connector 5, prevent the earmuff 3 from loosening during use, and improve the overall structural reliability of the headband 1.

[0038] Reference Figure 1 - Figure 7The limiting assembly includes a sliding post 17 and a limiting plate 15. The sliding post 17 is slidably connected to the inner wall of the connecting post 10 and can move axially along the inner wall of the connecting post 10, providing support for the position adjustment of the limiting plate 15. At the same time, it drives the locking rod 18 to move synchronously, realizing the switching of the limiting state. One side of the limiting plate 15 is fixedly connected to one end of the sliding post 17. Its diameter is larger than the diameter of the sleeve hole of the connecting piece 5. When it contacts the connecting piece 5, it can form an axial block to prevent the connecting post 10 from coming out of the connecting piece 5, ensuring the installation stability of the earmuff 3. One side of the limiting plate 15 contacts the connecting piece 5. The side wall of the limiting plate 15 has a positioning hole 19 for engaging with the bottom of the positioning post 13 to lock the limiting plate 15. The rotation and movement of the 5-axis limit plate 15 prevents the limiting components from loosening on their own. A handle 16 is fixedly connected to the other side of the limit plate 15, providing a convenient operating component for the user to grip and rotate, thereby rotating the limit plate 15 and the sliding column 17 to adjust the position of the locking rod 18. The other end of the sliding column 17 is fixedly connected to the locking rod 18, which can slide within the sliding groove 20 or rotate within the disc groove 21. The locking rod 18 restricts the axial movement range of the sliding column 17 through its cooperation with the groove. The inner wall of the connecting column 10 has a sliding groove 20, providing a channel for the locking rod 18 to slide axially, ensuring that the locking rod 18 moves in a fixed direction and preventing the sliding column 17 from shifting. The locking rod 18 is slidably connected to the sliding column 17. The inner wall of the moving groove 20 has a disc groove 21 inside the connecting column 10, which communicates with the sliding groove 20, providing rotation space for the locking rod 18. When the locking rod 18 rotates into the disc groove 21, the radial restriction of the groove body prevents the sliding column 17 from axially dislodging. The locking rod 18 is rotatably connected to the inner wall of the disc groove 21. The locking component includes a positioning column 13, which is slidably connected inside the hollow column 12 and can slide up and down along the inner wall of the hollow column 12. Its bottom can be inserted into the positioning hole 19 to lock, or disengage from the positioning hole 19 to unlock. It is the core component for controlling the state of the limiting component. The bottom of the positioning column 13 engages with the positioning hole 19, and a sliding disc 14 is fixedly connected to the outer wall of the positioning column 13. The positioning post 13 can slide synchronously with the positioning post 13, which not only seals the internal space of the hollow post 12 to prevent impurities from entering, but also provides a force fulcrum for the return spring 22, ensuring that the spring force can be effectively transmitted to the positioning post 13. The sliding plate 14 is slidably connected to the inner wall of the hollow post 12, and the positioning post 13 is fitted with a return spring 22 on the outer wall. In the natural state, the spring force pushes the sliding plate 14 to move downward, causing the bottom of the positioning post 13 to automatically engage with the positioning hole 19, ensuring the stability of the locked state. When the positioning post 13 is pressed, it can be compressed, providing elastic reset capability for unlocking operation. One end of the return spring 22 is fixedly connected to the inner wall of the hollow post 12, and the other end of the return spring 22 is fixedly connected to the top of the sliding plate 14.

[0039] Working principle: When installing the inner liner 2, the inner liner 2 is pushed to move the bottom fixed plate 6 towards the top fixed block 8 of the headband 1. This causes the slot 7 inside the plate 6 to align and engage with the pin 9 fixed on the side wall of the block 8, thus forming a stable connection between the inner liner 2 and the headband 1. When removing the inner liner 2, the inner liner 2 is slid in the opposite direction to move the plate 6 away from the block 8, thereby causing the slot 7 to disengage from the pin 9, thus enabling the inner liner 2 to be quickly removed and replaced.

[0040] When installing the earmuff 3, the connecting post 10 fixed to the side wall of the earmuff 3 is inserted into the connecting piece 5 fixed at both ends of the spring rod 4 inside the headband 1. This causes the limiting plate 15 fixed to one end of the sliding post 17 in the limiting assembly to contact the connecting piece 5. At this time, the positioning post 13 inside the hollow post 12 in the locking assembly, under the elastic force of the return spring 22 sleeved on its outer wall, causes the sliding plate 14 fixed to the outer wall of the positioning post 13 to slide down along the inner wall of the hollow post 12. This causes the bottom of the positioning post 13 to be inserted into the positioning hole 19 opened on the side wall of the limiting plate 15, thereby achieving stable positioning of the earmuff 3 inside the headband 1. The hollow post 12 is fixed inside the support block 11 fixed to the side wall of the connecting piece 5.

[0041] When disassembling the earmuff 3, pulling the positioning post 13 causes the sliding plate 14 to compress the return spring 22 and slide upward, thereby causing the bottom of the positioning post 13 to disengage from the positioning hole 19 and release the lock. Then, rotating the handle 16 fixed on the other side of the limiting plate 15 causes the limiting plate 15 and the sliding post 17 to rotate, thereby causing the locking rod 18 fixed on the other end of the sliding post 17 to rotate from the sliding groove 20 opened in the inner wall of the connecting post 10 into the disc groove 21 opened inside the connecting post 10. Finally, the sliding post 17 is pulled outward to cause the limiting plate 15 to disengage from the connecting piece 5, so that the connecting post 10 separates from the connecting piece 5 along with the earmuff 3, thus completing the disassembly of the earmuff 3.
