Since their advent, Bluetooth headsets have been a great tool for mobile business professionals to improve efficiency. Over-ear Bluetooth headsets feature an arc-shaped structure that fits snugly against the head, making them more comfortable and comfortable to wear. The larger headband also allows for greater battery life and enhanced functionality.

[0003] Currently, a Chinese patent discloses a Bluetooth headset (authorization announcement number CN222321755U). This utility model includes: a body component, which includes a first support ring, a second support ring, a first support plate, and a second support plate; and a folding component, which includes a first rotating shaft, a support frame, an insert block, a slot, a stop block, a spring, an inner groove, a docking block, and a second rotating shaft; the bottom of the first support ring and the second support ring are connected to the first rotating shaft, and the bottom of the first rotating shaft is rotatably connected to the first support plate and the second support plate, respectively; the lower part of the outer surface of the first support ring and the second support ring is connected to the support frame. To address the issue that existing over-ear Bluetooth headphones, being a single unit, are difficult to fold and store when not in use, resulting in them scattering on a table and taking up considerable space, the proposed solution has the following drawbacks: While the elasticity between the first and second support rings is used to secure the earpiece to the ear and prevent it from falling off, the elasticity is fixed. Excessive elasticity can cause ear or head pinching, while insufficient elasticity can result in an insecure fit. Utility Model Content

[0004] Therefore, it is necessary to provide a Bluetooth headset with high stability, addressing the issues of excessive elasticity causing ear or head clamping, and insufficient elasticity resulting in an unstable fit.

[0005] A highly stable Bluetooth headset includes: a headband, with telescopic frames fixedly connected to both sides of the headband, and Bluetooth headset bodies rotatably connected to the surfaces of both telescopic frames; the headband is provided with a clamping mechanism for adjusting the clamping force between the two Bluetooth headset bodies; wherein, the clamping mechanism includes mounting grooves symmetrically opening and closing on both sides of the headband, a rotating shaft fixedly connected in the mounting groove, the telescopic frames rotatably connected to the rotating shaft, a torsion spring provided in the mounting groove, and a stop bar corresponding to the torsion spring provided on the top of the telescopic frame.

[0006] In one embodiment, multiple rotating shafts are provided, and one end of the torsion spring is blocked by a stop bar, while the other end is blocked by a head beam.

[0007] In one embodiment, each of the stop bars has a slot corresponding to the torsion spring on the side near the torsion spring.

[0008] In one embodiment, a rotating frame is rotatably connected in the mounting slot, one end of the torsion spring is fixedly connected to the surface of the rotating frame, one end of the rotating frame is fixedly connected to an adjusting plate, a limit bolt is provided on the surface of the adjusting plate, and a positioning hole corresponding to the limit bolt is opened on the side of the head beam near the adjusting plate.

[0009] In one embodiment, the positioning hole is annularly disposed on one side of the head beam, and the surface of the adjusting disc has a limiting hole with the same diameter as the positioning hole, and the limiting bolt is threaded into the limiting hole.

[0010] In one embodiment, the surface of the adjustment disc is provided with anti-slip protrusions, and the surface of the torsion spring is provided with a wear-resistant layer.

[0011] In one embodiment, the rear end of the limiting bolt is provided with a thread of the same thickness as the limiting hole, and the front end of the limiting bolt is unthreaded.

[0012] In one embodiment, the headband is arc-shaped, and a silicone pad that fits against the headband is provided at the bottom of the headband.

[0013] Beneficial effects

[0014] A clamping mechanism is provided, which adjusts the force of the torsion spring acting on the telescopic frame by changing the snap-fit ​​position of one end of the torsion spring, thereby changing the clamping force between the two Bluetooth headset bodies, improving wearing comfort, and can be adjusted according to user preferences.

[0015] The rotating adjustment disc drives the rotating frame to rotate, thereby changing the position of the torsion spring and thus changing the amount of energy stored in the torsion spring. This alters the force exerted on the telescopic frame, enabling multiple adjustments and more precise control of the pressure between the two Bluetooth headsets. Attached Figure Description

[0028] The following is combined Figures 1-4 This invention describes a highly stable Bluetooth headset.

[0029] In one embodiment, a highly stable Bluetooth headset includes: a headband 100, telescopic frames 110 fixedly connected to both sides of the headband 100, Bluetooth headset bodies 111 rotatably connected to the surfaces of both telescopic frames 110, and a clamping mechanism 200 provided on the headband 100 for adjusting the clamping force between the two Bluetooth headset bodies 111; wherein, the clamping mechanism 200 includes mounting grooves 210 symmetrically opening and closing on both sides of the headband 100, a rotating shaft 211 fixedly connected in the mounting grooves 210, the telescopic frames 110 rotatably connected to the rotating shaft 211, a torsion spring 220 provided in the mounting grooves 210, and a stop bar 221 corresponding to the torsion spring 220 provided on the top of the telescopic frame 110.

[0030] like Figure 2 As shown, the rotating shaft 211 is provided with multiple shafts, and one end of the torsion spring 220 is blocked by the stop bar 221, while the other end is blocked by the head beam 100.

[0031] In this embodiment, one end of the torsion spring 220 is secured to one side of the stop bar 221 to limit the position of the torsion spring 220. When the telescopic frame 110 rotates, it compresses the torsion spring 220, causing the torsion spring 220 to deform. The torsion spring 220 generates a reverse force on the telescopic frame 110. By changing the position of the torsion spring 220 on the stop bar 221, the magnitude of the reverse force of the torsion spring 220 on the telescopic frame 110 is changed, thereby adjusting the pressure between the two Bluetooth headset bodies 111. This makes it easier for people with different head sizes to wear, ensuring wearing stability and avoiding problems such as pressure on the ears and head.

[0032] like Figure 2 As shown, each stop bar 221 has a corresponding slot on the side near the torsion spring 220.

[0033] In this embodiment, a slot is provided to better limit the torsion spring 220, preventing the torsion spring 220 from falling off the stop bar 221 and causing the headband 100 to fall off, thus ensuring the stability of wearing.

[0034] like Figure 3 and Figure 4 As shown, a rotating frame 230 is rotatably connected in the mounting groove 210. One end of a torsion spring 220 is fixedly connected to the surface of the rotating frame 230. An adjusting plate 232 is fixedly connected to one end of the rotating frame 230. A limit bolt 234 is provided on the surface of the adjusting plate 232. A positioning hole 231 corresponding to the limit bolt 234 is provided on the side of the head beam 100 near the adjusting plate 232.

[0035] In this embodiment, the limiting bolt 234 is pulled out from the positioning hole 231, the adjusting plate 232 is loosened, and under the action of the torsion spring 220, the rotating frame 230 drives the adjusting plate 232 to rotate, releasing the energy stored in the torsion spring 220. At this time, after one end of the torsion spring 220 is stuck on different stops 221, the adjusting plate 232 is rotated in the opposite direction to allow the torsion spring 220 to store energy again. The limiting bolt 234 is then reinserted into the positioning hole 231, completing the operation of changing the torsion spring 220 from one stop 221 to another. This facilitates the adjustment of the energy stored in the torsion spring 220 and makes it convenient to adjust the pressure of the telescopic frame 110.

[0036] like Figure 3 and Figure 4 As shown, the positioning hole 231 is arranged in a ring on one side of the head beam 100, and the surface of the adjusting plate 232 is provided with a limiting hole 233 with the same diameter as the positioning hole 231. The limiting bolt 234 is threaded into the limiting hole 233.

[0037] In this embodiment, multiple positioning holes 231 are arranged in a ring to realize multi-level adjustment of the torsion spring 220. The limit bolt 234 is screwed into the limit hole 233 to prevent the limit bolt 234 from falling off, so that the force of the torsion spring 220 on the telescopic frame 110 remains stable.

[0038] like Figure 4 As shown, the surface of the adjustment disc 232 is provided with anti-slip protrusions, and the surface of the torsion spring 220 is provided with a wear-resistant layer.

[0039] In this embodiment, the anti-slip protrusions facilitate the rotation of the adjustment disc 232 by hand, thereby applying force to the torsion spring 220. The wear-resistant layer is made of polyurethane, which combines flexibility and wear resistance, making it suitable for spring applications requiring dynamic bending.

[0040] like Figure 4 As shown, the rear end of the limiting bolt 234 is provided with a thread of the same thickness as the limiting hole 233, and the front end of the limiting bolt 234 is not threaded.

[0041] In this embodiment, the rear end is threaded to facilitate locking the position of the limiting bolt 234 and prevent the limiting bolt 234 from falling out of the limiting hole 233. The front end is unthreaded to facilitate the insertion of the limiting bolt 234 into the limiting hole 233.

[0042] like Figure 1 As shown, the headband 100 is arc-shaped, and a silicone pad that fits against the bottom of the headband 100 is provided.

[0043] In this embodiment, the arc-shaped design fits the user's head better, increasing the contact area with the head, reducing pressure, and improving wearing comfort. The silicone pad is also more skin-friendly, making it more comfortable to wear.

[0044] Working principle: The telescopic frame 110 is extended or retracted according to the size of the head, increasing the wearing range so that the Bluetooth headset body 111 covers the ears. By pulling the limiting bolt 234 out of the positioning hole 231 and rotating the adjustment disc 232, the rotating frame 230 is rotated, thereby changing the compression of the torsion spring 220. This adjusts the force exerted by the torsion spring 220 on the telescopic frame 110, allowing for multiple levels of adjustment to improve wearing comfort according to user needs.

[0045] It should be noted that the torsion spring 220 and limit bolt 234 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs, and will not be elaborated here.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
