Description

Technical Field

[0001] This utility model relates to the field of electronic earmuff headband technology, and in particular to an exposed hollow headband. Background Technology

[0002] With the deep integration of consumer electronics and wearable devices, headphones have become an important tool for daily communication, entertainment, and professional audio monitoring. As its core supporting structure, the design of the headband directly affects the overall wearing experience and functional reliability of the product. An exposed hollow headband has emerged, which aims to solve the inherent defects of traditional designs in terms of long-term comfort and internal cable management through structural innovation, meet users' dual needs for high performance and high comfort, and is a key research direction to enhance the competitiveness of the head-mounted device market.

[0003] Existing headband structures mostly adopt a solid or semi-enclosed strip design with one-piece injection molding. The main body relies on the rigidity of the material itself to provide clamping force. The internal cables are usually initially fixed by simple plastic clips or adhesive cable trays. There is a lack of effective centralized management and locking mechanism. Although the structure can guarantee basic support function, it does not consider heat dissipation and wiring. The structural design tends to be conservative and fails to achieve in-depth optimization of functional modules.

[0004] The main problem with existing technology is that its structural design neglects the comfort requirements of long-term wear. Since the main body of the headband is mostly a closed or low-breathability structure, it seriously hinders the heat exchange between the head and the air, resulting in heat accumulation that is difficult to dissipate. Users are prone to discomfort such as stuffiness and sweating during use, which significantly affects the continuity and comfort of the wearing experience. This is a prominent defect in the current product design that needs to be improved. To address this issue, an exposed hollow headband is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an exposed hollow headband, which aims to improve the problems of traditional headbands being stuffy and having unstable electronic circuits when worn.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an exposed hollow headband, comprising a headband body, with connecting blocks at both ends of the headband body, electronic earmuffs on the sidewalls of the connecting blocks, fixing blocks fixedly connected to both sides of the electronic earmuffs, multiple hollow openings inside the headband body, two rows of wire harness assemblies at the top of the headband body, and limit components inside the connecting blocks;

[0007] The cable harness assembly includes a buckle plate, a fixed buckle, and a connecting groove inside the headband body. The buckle plate and the connecting groove are fitted together. The bottom of the fixed buckle is fixedly connected to the outer wall of the buckle plate. A rotating buckle is rotatably connected inside the buckle plate. A limiting block is fixedly connected to the bottom of the rotating buckle. The limiting block and the connecting groove are engaged.

[0008] As a further description of the above technical solution:

[0009] The limiting component includes a slot formed on the inner wall of the connecting block, a slot formed inside the fixing block, and a ball, wherein the slot and the fixing block are fitted together.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the ball is slidably connected to the inside of the connecting block, and the ball and the hole engage with each other.

[0012] As a further description of the above technical solution:

[0013] The ball-holding sidewall is fixedly connected to a limiting plate, and the outer wall of the limiting plate is slidably connected inside the connecting block.

[0014] As a further description of the above technical solution:

[0015] A sliding block is fixedly connected to the outer wall of the limiting plate, and the outer wall of the sliding block is slidably connected inside the connecting block.

[0016] As a further description of the above technical solution:

[0017] The limiting plate is provided with a telescopic rod on its side wall. One end of the telescopic rod is fixedly connected to the side wall of the limiting plate, and the other end of the telescopic rod is fixedly connected to the inside of the connecting block.

[0018] As a further description of the above technical solution:

[0019] A return spring is fitted on the outer wall of the telescopic rod. One end of the return spring is fixedly connected to the side wall of the limiting plate, and the other end of the return spring is fixedly connected to the inside of the connecting block.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the hollow opening inside the headband body allows for efficient ventilation, preventing stuffiness caused by prolonged wear. Simultaneously, the two rows of buckles at the top of the headband body securely fix the electronic circuitry, preventing it from shifting or loosening. This achieves excellent ventilation while wearing the headband, as well as stable and convenient fixation of the electronic circuitry, solving the problems of stuffiness and insecure electronic circuitry fixation in traditional headbands. This improves the comfort and stability of the product.

[0022] 2. In this utility model, when installing electronic earmuffs, the fixing block is initially fixed by aligning and fitting it into the slot. During the installation process, the outer wall of the fixing block presses against the retaining ball, causing it to drive the limiting plate and sliding block to press against the telescopic rod and the return spring. When the fixing block is fully engaged, the return spring releases its elastic potential energy, causing the retaining ball to engage in the retaining hole, achieving a stable fixation effect. This makes the installation of electronic earmuffs convenient and stable, solving the problem of cumbersome and unstable installation of traditional electronic earmuffs, and improving the efficiency of installation and the stability of the structure.

[0033] 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.

[0034] Reference Figures 1-4 This utility model provides an embodiment of an exposed, hollowed-out headband, comprising a headband body 1. The headband body 1 serves as an overall support structure, supporting various components and conforming to the head for a stable wearing effect. Connecting blocks 2 are provided at both ends of the headband body 1, connecting the headband body 1 and electronic earmuffs 3, acting as a transitional connection to ensure a stable connection. Electronic earmuffs 3 are provided on the sidewalls of the connecting blocks 2, providing audio playback or hearing protection functions to meet user needs. Fixing blocks 11 are fixedly connected to both sides of the electronic earmuffs 3. The fixing block 11 works in conjunction with the internal structure of the connecting block 2 to connect the electronic earmuff 3 to the connecting block 2, achieving the effect of installation and fixation. The headband body 1 has multiple hollow openings 4 inside, which are used to increase the breathability of the headband, reduce heat accumulation at the contact point between the head and the headband, and improve wearing comfort. The top of the headband body 1 is provided with two rows of wire harness components, which are used to organize and fix the electronic circuits and prevent the circuits from being messy and shaking. The connecting block 2 is provided with a limiting component inside, which is used to strengthen the connection strength between the electronic earmuff 3 and the connecting block 2 and ensure that the connection between the two is stable.

[0035] The wiring harness assembly includes a buckle plate 5, a fixing buckle 6, and a connecting groove 8 inside the headband body 1. The buckle plate 5 and the connecting groove 8 fit together, allowing the buckle plate 5 to be stably installed on the headband body 1, providing support for subsequent components. The bottom of the fixing buckle 6 is fixedly connected to the outer wall of the buckle plate 5. The fixing buckle 6 is used to initially restrict the position of the electronic circuit and prevent the circuit from moving at will. The buckle plate 5 is rotatably connected to a rotating buckle 7. The rotating buckle 7 can rotate around the buckle plate 5, forming a closed space with the fixing buckle 6 to firmly fix the electronic circuit. The bottom of the rotating buckle 7 is fixedly connected to a limiting block 9. The limiting block 9 and the connecting groove 8 engage. The connecting groove 8 is used to fix the position of the rotating buckle 7, preventing it from accidentally rotating and causing the circuit to loosen, thus achieving a stable locking effect.

[0036] Reference Figures 5-8 The limiting component includes a slot 10 formed on the inner wall of the connecting block 2, a slot 12 formed inside the fixing block 11, and a ball 13. The slot 10 and the fixing block 11 are engaged to form a preliminary positioning and connection, laying the foundation for subsequent fixing. The outer wall of the ball 13 is slidably connected to the inside of the connecting block 2, and the ball 13 can slide back and forth within the connecting block 2. The ball 13 and the slot 12 are engaged to further lock the fixing block 11 and the connecting block 2, achieving a stable fixing effect. A limiting plate 14 is fixedly connected to the side wall of the ball 13. The outer wall of the limiting plate 14 is slidably connected to the inside of the connecting block 2. The limiting plate 14 is used to limit the sliding range of the ball 13 and prevent the ball 13 from falling out of the connecting block 2. A sliding block 15 is fixedly connected to the outer wall of the limiting plate 14. The outer wall of the sliding block 15 is slidably connected to the inside of the connecting block 2. The sliding block 15 moves with the connecting block 2. The limiting plate 14 slides together to help it maintain a stable sliding direction and prevent it from deviating during sliding. A telescopic rod 16 is provided on the side wall of the limiting plate 14. One end of the telescopic rod 16 is fixedly connected to the side wall of the limiting plate 14, and the other end is fixedly connected to the inside of the connecting block 2. The telescopic rod 16 can extend and retract with the movement of the limiting plate 14 to support the limiting plate 14 and assist it in resetting. A reset spring 17 is sleeved on the outer wall of the telescopic rod 16. One end of the reset spring 17 is fixedly connected to the side wall of the limiting plate 14, and the other end is fixedly connected to the inside of the connecting block 2. The reset spring 17 deforms and stores elastic potential energy when the limiting plate 14 moves. When the external force disappears, it releases the potential energy, driving the limiting plate 14 and the locking ball 13 to reset, ensuring that the locking ball 13 can accurately lock into the locking hole 12. Further details are omitted here.

[0037] Working principle: When wearing the headband, the multiple hollow openings 4 inside the headband body 1 form an air circulation channel. When wearing it, the heat of the head can be quickly exchanged with the outside through the hollow area, reducing heat accumulation and avoiding the stuffiness caused by wearing it for a long time, directly improving wearing comfort. At the same time, the two rows of cable assemblies at the top of the headband body 1 are responsible for fixing the electronic circuit. The buckle plate 5 and the connecting groove 8 fit together to form the installation base. When the buckle 7 is rotated around the buckle plate 5, the limiting block 9 at the bottom of the buckle 7 is engaged with the connecting groove 8, locking the position of the buckle 7 and ensuring that the circuit is firmly fixed to prevent shaking or loosening. Then, the buckle 7 and the fixed buckle 6 together clamp the circuit to achieve stable and convenient cable management.

[0038] When installing the electronic earmuff 3, the fixing blocks 11 on both sides of the electronic earmuff 3 are aligned with the slots 10 on the inner wall of the connecting block 2 and inserted to form a preliminary positioning. During the insertion process, the outer wall of the fixing block 11 presses the retaining ball 13, causing the retaining ball 13 to drive the limiting plate 14 and the sliding block 15 to slide into the connecting block 2. At the same time, the limiting plate 14 presses the telescopic rod 16 and the return spring 17, causing the return spring 17 to store elastic potential energy. When the fixing block 11 is fully engaged, the retaining ball 13 is aligned with the retaining hole 12 on the fixing block 11. The return spring 17 releases its potential energy, pushing the limiting plate 14 and the retaining ball 13 to reset. The retaining ball 13 is then inserted into the retaining hole 12, completing the stable fixation of the electronic earmuff 3 and avoiding the problem of easy loosening in traditional connection methods.
