Description

Technical Field

[0001] This utility model relates to the field of headphone technology, and in particular to a Bluetooth headphone. Background Technology

[0002] Bluetooth headsets integrate Bluetooth wireless communication technology into the headset, freeing users from the constraints of traditional wired headphones. Since their introduction, Bluetooth headsets have become an important tool for mobile business professionals to improve work efficiency. Among them, ear-hook Bluetooth headsets are widely favored by users due to their compact and portable design.

[0003] Currently, ear-hook Bluetooth headphones on the market mainly consist of an ear hook and the main body of the earphone. In traditional designs, the ear hook is usually fixedly connected to the main body, lacking adjustable flexibility. This structural design makes it difficult for the headphones to adapt to the different ear sizes of different users, preventing flexible adjustments during wear and thus affecting the optimal fit between the earbud and the driver unit and the human ear. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a Bluetooth headset, which aims to solve the technical problems mentioned in the background art.

[0005] A Bluetooth headset includes a bottom cover, a hinge base, and an ear hook. The bottom cover and the hinge base are rotatably connected about the vertical axis of the bottom cover. The ear hook includes an ear hook portion and a connecting portion. The ear hook portion is connected to the hinge base through the connecting portion. The ear hook portion and the hinge base are rotatably connected about the horizontal axis of the hinge base. The vertical axis of the bottom cover is perpendicular to the horizontal axis of the hinge base.

[0006] The bottom cover is provided with a battery compartment and a contact part. The inner wall of the pivot base is provided with a snap-fit ​​groove. The side wall of the pivot base is provided with a contact part. The battery compartment is interference-fitted with the snap-fit ​​groove. The position of the contact part corresponds to that of the contact part.

[0007] The connecting part includes a pivot pin, a torsion spring, and a sleeve. The torsion spring and the sleeve are sleeved on the pivot pin. The torsion spring is located inside the sleeve. The pivot pin is connected to the sleeve through the torsion spring. The pivot base is connected to the pivot pin through a snap-fit ​​component.

[0008] The beneficial effects of this utility model are:

[0009] This earphone allows for rotation in two directions. First, rotation occurs between the bottom cover and the rotating base along the vertical axis of the bottom cover. This is achieved through an interference fit between the battery compartment on the bottom cover and the inner wall of the rotating base, allowing the rotating base to rotate. The abutment part of the bottom cover engages with the abutment part of the rotating base, acting as a limiter during rotation and adapting to different ear angles. Second, rotation occurs between the ear hook and the rotating base along the horizontal axis of the rotating base. Twisting the ear hook causes the rotating pin to twist, which in turn causes the torsion spring to rotate. A sleeve restricts the rotation of the rotating pin at a certain angle. The torsion spring's automatic return function allows the ear hook to rotate, adapting to different ear shapes. This invention aims to provide high wearing adaptability (through rotation in two directions) and a good user experience (through the rotational feel provided by the torsion spring or the automatic return function) to meet the needs of different users.

[0010] Furthermore, the battery compartment is annular in shape, and the inner wall of the battery compartment is provided with an annular boss, which is interference-fitted with the snap-fit ​​groove.

[0011] Furthermore, the abutting part is provided on the periphery of the battery compartment, the abutting part is wavy, and the two opposite ends of the abutting part are provided with limiting parts.

[0012] Furthermore, the abutting member includes an abutting post and a bead disposed at the end of the abutting post. The abutting post is disposed on the side wall of the rotating shaft base, and the bead abuts against the abutting part. The bead is adapted to the abutting part.

[0013] Furthermore, the side wall of the rotating shaft base is recessed to form a receiving cavity, and the receiving cavity communicates with the interior of the rotating shaft base through a through hole.

[0014] Furthermore, the pivot pin includes a platform portion and a snap-fit ​​portion and a column portion disposed on two opposite sides of the platform portion. The snap-fit ​​portion is fixedly connected to the lug portion. The platform portion and the column portion are disposed in the receiving cavity. One end of the column portion away from the platform portion passes through the through hole. The column portion is provided with a groove. The snap-fit ​​member is disposed on the groove. The end face of the snap-fit ​​member abuts against the inner wall of the pivot base.

[0015] Furthermore, the platform portion is provided with a first fixing hole and a protrusion. The first fixing hole penetrates the platform portion, and the protrusion is located on the periphery of the platform portion. The torsion spring and the sleeve are sleeved on the cylindrical portion. The sleeve includes a first arc-shaped portion and a second arc-shaped portion. The opposite ends of the first arc-shaped portion are connected to the opposite ends of the second arc-shaped portion. The first arc-shaped portion is provided with a second fixing hole. The opposite ends of the torsion spring are respectively connected to the first fixing hole and the second fixing hole. The protrusion is located inside the second arc-shaped portion and abuts against the inner wall of the second arc-shaped portion.

Embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0027] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Furthermore, the various embodiments of the invention, the features within those embodiments, and the features of the embodiments may be freely combined without obvious conflict or contradiction.

[0029] See Figures 1 to 7As shown, a Bluetooth headset includes a bottom cover 1, a hinge base 2, and an ear hook 3. The bottom cover 1 and the hinge base 2 are rotatably connected about the vertical axis of the bottom cover 1. The ear hook 3 includes an ear hook portion 31 and a connecting portion 32. The ear hook portion 31 is connected to the hinge base 2 through the connecting portion 32, and the ear hook portion 31 and the hinge base 2 are rotatably connected about the horizontal axis of the hinge base 2. The bottom cover 1 is provided with a battery compartment 11 and an abutment portion 12. The inner wall of the hinge base 2 is provided with a snap-fit ​​groove 21 and a connecting post 211. A reinforcing plate is sleeved on the connecting post 211. 212, the reinforcing plate 212 is located in the snap-fit ​​groove 21, the side wall of the rotating shaft base 2 is provided with an abutment 22, the battery compartment 11 is interference-fitted with the snap-fit ​​groove 21, and the abutment part 12 corresponds to the position of the abutment part 22; the connecting part 32 includes a rotating shaft pin 321, a torsion spring 322 and a sleeve 323, the torsion spring 322 and the sleeve 323 are sleeved on the rotating shaft pin 321, the torsion spring 322 is located in the sleeve 323, the rotating shaft pin 321 is connected to the sleeve 323 through the torsion spring 322, and the rotating shaft base 2 is connected to the rotating shaft pin 321 through the snap-fit ​​33. It can rotate in two directions. First, it rotates between the bottom cover 1 and the rotating shaft base 2. It is firmly fixed by the interference fit between the battery compartment 11 on the bottom cover 1 and the snap-fit ​​groove 21 on the inner wall of the rotating shaft base 2. To ensure structural strength, a reinforcing plate 212 is added in the snap-fit ​​groove 21 to allow the rotating shaft base 2 to rotate. The abutting part 12 of the bottom cover 1 and the abutting part 22 of the rotating shaft base 2 cooperate to limit the rotation and adapt to the ear angle. Second, it rotates between the ear hook 31 and the rotating shaft base 2. Twisting the ear hook 31 drives the rotating shaft pin 321 to twist the torsion spring 322. The sleeve 323 restricts the rotation of the rotating shaft pin 321 at a certain angle. The automatic return function of the torsion spring 322 is used to allow the ear hook 31 to rotate to adapt to different ear shapes.

[0030] It is worth mentioning that the rotation in the two directions is not simultaneous and can be adjusted flexibly according to specific needs.

[0031] Specifically, the battery compartment 11 is annular in shape, and its inner wall has an annular protrusion 111, which is interference-fitted with the snap-fit ​​groove 21. The annular protrusion 111 divides the battery compartment 11 into upper and lower parts: the lower part is used to accommodate the battery, and the upper part abuts against the inner wall of the snap-fit ​​groove 21 through the annular protrusion 111. This design increases the contact area, forms a stable interference-fit connection, and also serves as the rotation axis between the bottom cover 1 and the rotating shaft base 2.

[0032] Specifically, the abutment portion 12 is located on the periphery of the battery compartment 11. The abutment portion 12 is wavy, and limiting portions 121 are provided at opposite ends of the abutment portion 12. The abutment member 22 includes an abutment post 221 and a ball bearing 222 located at the end of the abutment post 221. The abutment post 221 is located on the side wall of the rotating shaft base 2. The ball bearing 222 abuts against the abutment portion 12, and the ball bearing 222 is adapted to the abutment portion 12. When the pivot base 2 rotates relative to the bottom cover 1, the ball bearing 222 moves along the abutment portion 12. Because the abutment portion 12 is wavy, the ball bearing 222 abuts against the trough of the abutment portion 12. The maximum rotation angle between the bottom cover 1 and the pivot base 2 is 38°. In this embodiment, the rotation angle of the abutment portion 12 is divided into 5 equal parts to ensure that the rotation angle is uniform and controllable. The two opposite ends of the abutment portion 12 are restricted by the limiting portion to form a restriction 121, so that the movement trajectory of the ball bearing 222 does not leave the abutment portion 12.

[0033] Specifically, the side wall of the pivot base 2 is recessed to form a receiving cavity 23, which is connected to the interior of the pivot base 2 through a through hole 24. The pivot pin includes a platform portion 3211 and a snap-fit ​​portion 3212 and a column portion 3213 on opposite sides of the platform portion 3211. The snap-fit ​​portion 3212 is fixedly connected to the lug portion 31. The platform portion 3211 and the column portion 3213 are located in the receiving cavity 23. The end of the column portion 3213 away from the platform portion 3211 passes through the through hole 24. The column portion 3213 is provided with a groove 32131, and a snap-fit ​​member 33 is provided on the groove 32131. The end face of the snap-fit ​​member 33 abuts against the inner wall of the pivot base 2. The platform portion 3211 is provided with a first fixing hole 32111 and a protrusion 32112. The first fixing hole 32111 penetrates the platform portion 3211, and the protrusion 32112 is provided on the periphery of the platform portion 3211. The torsion spring 322 and the sleeve 323 are sleeved on the column portion 3213. The sleeve 322 includes a first arc-shaped portion 3221 and a second arc-shaped portion 3222. The two opposite ends of the first arc-shaped portion 3221 are connected to the two opposite ends of the second arc-shaped portion 3222. The first arc-shaped portion 3221 is provided with a second fixing hole 32211. The two opposite ends of the torsion spring 322 are connected to the first fixing hole 32111 and the second fixing hole 32211 respectively. The protrusion 32112 is located inside the second arc-shaped portion 3222 and abuts against the inner wall of the second arc-shaped portion 3222.

[0034] It should be noted that the interference fit between the snap-fit ​​member 33 and the inner wall of the shaft base 2 provides axial constraint, and the abutment between the protrusion 32112 and the inner wall of the sleeve 323 achieves circumferential limitation, that is, the maximum rotation angle is 30°, which synergistically improves the vibration resistance and rotational stability of the structure. The precise positioning of the first fixing hole 32111 and the second fixing hole 32211 ensures that the preload of the torsion spring 322 is uniform, avoiding eccentric wear. The torsion spring 322 is linked with the sleeve 323 and the shaft pin 321 through the first fixing hole 32111 and the second fixing hole 32211, providing controllable damping during rotation, suppressing axial movement during high-speed rotation, and extending the service life of the mechanism. The receiving groove 23 is integrated into the side wall of the shaft base 2, reducing additional installation space. The embedded fit between the protrusion 32112 and the sleeve 323 further compresses the radial dimension. This structure, through mechanical interlocking and the synergy of elastic elements, significantly improves the rigidity, accuracy and environmental adaptability of the shaft system.

[0035] Understandably, the bottom cover 1 also has an earphone compartment.

[0036] This invention aims to provide high wearing adaptability (through rotation in two directions) and a good user experience (through the rotational feel or automatic return function provided by the torsion spring 322) to meet the needs of different users.
