[0003] For ear-hook wireless Bluetooth headsets, they include: ear-hook components and a movement body. When in use, the ear-hook components are hung on the auricle, and the sound-generating part of the movement body corresponds to the ear canal. For bone conduction headphones, the movement body can be placed against the skin on both sides of the human head.
[0004] Compared with ordinary earbud headphones, earhook headphones have an additional earhook component, so the entire headphone product is larger in size, and the relative angle between the earhook component and the main body of the movement cannot be adjusted, so it is not convenient to store.
[0005] In addition, ear-hook Bluetooth headsets are usually designed according to the heads of mainstream people during design and production, so they are not completely suitable for every different user. Due to their physical differences, different users cannot fully adapt when wearing and using them. The existing ear-hook Bluetooth headsets cannot be adjusted, which brings inconvenience to users.

[0027] The present invention is further described below in conjunction with specific embodiments and drawings.
[0028] The present invention is a dual-gear rotating mechanism. Figures 1 to 4 As shown, it includes: a base 1, a rotating arm 2, a torsion spring 3, a pivot 4, an angle clip 5 and a friction plate 6.
[0029] The base 1 comprises: a pivoting portion 11 pivotally connected to the pivot 4 and an extension portion 12 integrally formed with the pivoting portion 11, and the rotating arm 2 comprises: a rotating portion 21 pivotally connected to the pivot 4 and an extension arm 22 integrally formed with the rotating portion 21. The pivoting portion 11 and the rotating portion 21 are correspondingly superimposed on each other, and the pivot 4 passes through the pivoting portion 11 and the rotating portion 21 to achieve a rotatable pivot connection between the two. In this embodiment, the pivoting portion 11 and the rotating portion 21 are designed to be disc-shaped.
[0030] In order to allow the base 1 and the rotating arm 2 to reset themselves, a torsion spring 3 is arranged between the base 1 and the rotating arm 2, and the torsion spring 3 provides elastic force for restoring the base 1 and the rotating arm 2. The specific installation structure is: a recessed area 10 is formed on the pivoting portion 11 of the base 1. The torsion spring 3 is located in the recessed area 10, and the spring body of the torsion spring 3 is sleeved on the pivot 4, and the pins at both ends of the torsion spring 3 are respectively linked to the base 1 and the rotating arm 2 through positioning pins.
[0031] In order to limit the rotation angle between the base 1 and the rotating arm 2, a first limiting groove 13 is provided on the base 1, and a limiting pin 26 corresponding to the first limiting groove 13 is fixed on the rotating arm 2. The first limiting groove 13 is an arc groove, and the limiting pin 26 on the rotating arm 2 falls into the first limiting groove 13. When the base 1 and the rotating arm 2 rotate relative to each other, the limiting pin 26 rotates along the first limiting groove 13, thereby limiting the rotation angle between the base 1 and the rotating arm 2. The limiting pin 26 can also serve as a positioning pin connecting the torsion spring 3 and the rotating arm 2.
[0032] A corner clip 5 is pivotally connected to the pivoting portion 11 of the base 1. The corner clip 5 is symmetrically arranged, and two ends of the long axis direction of the corner clip 5 are respectively formed with double corner clips 50. The side surface 51 connecting the two ends of the double corner clips 50 in the corner clip 5 is an inwardly concave arc surface, and the two side surfaces in the short axis direction of the corner clip 5 are inwardly concave arc surfaces. In addition, two outwardly extending corner clip tentacles 52 are formed in the double corner clip 50, and an obtuse angle recess 53 is formed between the adjacent side walls of the two corner clip tentacles 52.
[0033] Due to the existence of the corner clip 5, in order to allow the base 1 and the rotating arm 2 to rotate relative to each other, a corresponding space must be reserved on the rotating portion 21 of the rotating arm 2 so that the corner clip 5 has an area for relative movement. In this embodiment, a hollow matching area 20 is formed on the rotating portion 21 of the rotating arm 2 along the outer area of the pivot 4, and the matching area 20 is to provide an area for the corner clip 5 to move relative to each other during the rotation process. A clamping position 23 for accommodating the corner clip 5, as well as a middle feeler 24 and a side feeler 25 are respectively arranged along the side of the matching area 20; wherein, the clamping position 23 can be used to accommodate the corner clip 5, and when the base 1 and the rotating arm 2 rotate relative to each other, the middle feeler 24 and the side feeler 25 interfere with one of the double-angle clamping positions 50 in the corner clip 5, thereby driving the corner clip 5 to rotate. In this embodiment, the distance between the middle feeler 24 and the pivot 4 is smaller than the distance between the side feeler 25 and the pivot 4. In this way, although the middle feeler 24 can move the corner clip 5 in the long axis direction, it can still go over the short axis direction of the corner clip 5, thereby ensuring the relative rotation between the base 1 and the rotating arm 2.
[0034] A friction plate 6 is provided between the base 1 and the rotating arm 2. The friction plate 6 is fixed on the surface of the base 1, and the corner clip 5 is located on the surface of the friction plate 6. The friction plate 6 can provide a certain amount of rotation damping. Figure 3 and Figure 5As shown, the center of the friction plate 6 is positioned by the pivot 4, and the pivot 501 for pivoting the corner clip 5 passes through the friction plate 6, so that the friction plate 6 is fixed to the pivot portion 11 of the base 1, and keeps running synchronously with the base 1. At the same time, since the corner clip 5 is located above the friction plate 6, a certain friction force will be formed between the corner clip 5 and the friction plate 6 when the corner clip 5 rotates. The friction force can ensure that the corner clip 5 will not rotate by itself, and will only rotate under the action of external force. When the external force disappears, the corner clip 5 will stop immediately under the action of the friction force, thereby ensuring the accuracy of the rotation angle of the corner clip 5 and no excess rotation margin.
[0035] Combine the following Figure 6 As shown, the working principle of the present invention is described:
[0036] State A: In this state, the obtuse-angled recessed position 53 of the double-angle clamping position 50 in the upper middle of the corner clamp 5 just abuts against the middle tentacle 24. At this time, the rotational torque formed by the rotating arm 2 through the torsion spring 3 is not enough to drive the double-angle clamping position 50 to rotate, so the two are in a relatively stable state. At this time, the base 1 and the rotating arm 2 are in a relatively stable first gear position.
[0037] State B: When the base 1 and the rotating arm 2 need to be closed, the rotating arm 2 is rotated counterclockwise. At this time, the rotating arm 2 overcomes the torque of the torsion spring 3, driving the side feeler 25 to push the side of the double-angle clamp 50 below the corner clamp, causing the corner clamp 5 to rotate counterclockwise until the double-angle clamp 50 above the corner clamp 5 passes over the middle feeler 24.
[0038] State C: At this time, the rotational force applied to the base 1 and the rotating arm 2 is cancelled. Under the elastic force of the torsion spring 3, the base 1 and the rotating arm 2 will rotate relative to each other, that is, the rotating arm 2 will rotate clockwise. At this time, the torque of the rotating arm 2 is sufficient to drive the corner clip 5 to rotate, thereby pushing the middle antenna 24 from the upper right side of the corner clip 5 to rotate counterclockwise.
[0039] State D: When the middle antenna 24 is pushed by the upper right side of the corner clip 5 to rotate counterclockwise, the middle antenna 24 passes over the corner clip 5 clockwise by utilizing the inwardly concave side surface 51 of the corner clip 5 .
[0040] State E: After the middle feeler 24 passes over the corner clip 5 clockwise, under the action of the torsion spring 3, as the rotating arm 2 continues to rotate clockwise, the corner clip 5 falls into the clip position 23, and the base 1 and the rotating arm 2 are relatively stable. At this time, the base 1 and the rotating arm 2 remain in the closed state. The base 1 and the rotating arm 2 are in the relatively stable second gear.
[0041] When the rotating arm 2 needs to be opened, the rotating arm 2 is rotated counterclockwise again to overcome the torque of the torsion spring 3, and the corner clip 5 is pushed back to state A through the side feeler 25.
[0042] See Figure 7As shown, this is a schematic diagram of the present invention used in an ear-hook type earphone, and the ear-hook type earphone generally includes: an ear-hook component 71 and a core component 72. When the present invention is used in the ear-hook type earphone, the rotating arm 2 is built into the ear-hook component 71, the base 1 is built into the core component 72, and the ear-hook component 71 and the core component 72 are pivotally connected by a pivot 4. In this way, the user can adjust the angle between the ear-hook component 71 and the core component 72 as needed, so that the user can obtain a better hearing effect.
[0043] Of course, the above description is only a specific embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. All equivalent changes or modifications made according to the structure, characteristics and principles described in the patent application scope of the present invention should be included in the patent application scope of the present invention.
