[0003] In the related art, there is a headset that can realize the rotation of the headset body relative to the headband assembly by means of a rotating shaft, and in order to prevent the rotating shaft from falling out of the corresponding shaft hole, an anti-drop nut connected to the rotating shaft is provided, and in addition, in order to prevent the anti-drop nut from generating friction with other components when rotating with the rotating shaft, a wear-resistant ring sleeved on the outside of the rotating shaft is provided between the anti-drop nut and other components. However, for the convenience of installation, the inner diameter of the wear-resistant ring is usually larger than the outer diameter of the rotating shaft, which may cause the anti-drop nut to rotate relative to the wear-resistant ring, causing the wear-resistant ring to move in the radial direction of the rotating shaft, thereby causing the contact area between the anti-drop nut and the wear-resistant sheet to change, thereby causing the friction force to change, affecting the rotation stability. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model provides an ear fork assembly, which can improve the rotation stability.

[0005] The utility model also provides a headset with the ear fork assembly.

[0006] According to the embodiment of the first aspect of the utility model, the ear fork assembly comprises: a connecting arm; an ear fork, one of the ear fork and the connecting arm is provided with an axial hole, and the other is provided with a mounting position arranged opposite to the axial hole, and the edge of the axial hole at one end away from the mounting position is provided with a positioning chamfer; a rotating shaft mechanism, the rotating shaft mechanism comprises a rotating shaft, an anti-slip part and a wear-resistant ring, one end of the rotating shaft is arranged at the mounting position and is limited in the mounting position, and the rotating shaft is rotatably passed through the axial hole, one side of the wear-resistant ring is provided with a positioning inclined surface, the wear-resistant ring is sleeved on the end of the rotating shaft away from the mounting position, and the positioning inclined surface is positioned and matched with the surface of the positioning chamfer, the anti-slip part is sleeved on the end of the rotating shaft away from the mounting position, and is pressed on the side of the wear-resistant ring away from the positioning chamfer.

[0007] The ear fork assembly according to the embodiment of the utility model has at least the following beneficial effects:

[0008] In the ear fork assembly of the utility model, the connecting arm is used to connect the headband assembly, the ear fork is connected to the connecting arm by a rotating shaft mechanism, and the ear fork is used to connect the earphone body; the ear fork can rotate relative to the connecting arm, thereby driving the earphone body to rotate to adjust the angle of the earphone body. One end of the rotating shaft is inserted into the installation position and is restricted from being disengaged from the installation position, and the rotating shaft is rotatably inserted into the shaft hole, so that the ear fork can be rotated relative to the connecting arm by relying on the rotating shaft. In addition, by sleeve-arranging an anti-slipping member at one end of the rotating shaft away from the installation position, the anti-slipping member can be relied on to restrict the rotating shaft from being disengaged from the shaft hole. In addition, by sleeve-arranging a wear-resistant ring at one end of the rotating shaft away from the installation position, and pressing the anti-slipping member on the wear-resistant ring, when the rotating shaft rotates, the anti-slipping member will be driven to rotate relative to the wear-resistant ring, and a friction effect will be generated between the wear-resistant ring and the anti-slipping member. Among them, the edge of the end of the shaft hole away from the installation position is provided with a positioning chamfer; one side of the wear-resistant ring is provided with a positioning inclined surface, and the positioning inclined surface is positioned and matched with the surface of the positioning chamfer, and the anti-slipping member is pressed on the side of the wear-resistant ring away from the positioning chamfer. It can be understood that the positioning chamfer is formed by opening a chamfer on the edge of the end of the shaft hole away from the installation position, and the entire positioning chamfer is an annular structure, and the surface of the positioning chamfer is inclined. The positioning bevel on the side of the wear-resistant ring close to the installation position is adapted to the surface of the positioning chamfer. In this way, when the positioning chamfer of the positioning bevel of the wear-resistant ring fits, the positioning chamfer has the effect of centering the entire wear-resistant ring, which can reduce the risk of the wear-resistant ring being offset in the radial direction of the shaft hole. In this way, the risk of the wear-resistant ring being offset in the radial direction of the shaft hole due to the rotation of the anti-slip part relative to the wear-resistant ring can be reduced, thereby reducing the risk of changes in the contact area between the anti-slip part and the wear-resistant ring, or the contact area between the wear-resistant ring and the connecting arm, thereby improving the stability of the ear fork when rotating relative to the connecting arm.

[0009] According to some embodiments of the present invention, the wear-resistant ring is provided with a plurality of avoidance grooves spaced apart along the circumference of the wear-resistant ring from the positioning inclined surface.

[0011] According to some embodiments of the utility model, the anti-slip component is threadedly connected to the rotating shaft, and the anti-slip component can be operably rotated and moved along the axial direction of the rotating shaft to change the pre-tightening force between the anti-slip component and the wear-resistant ring.

[0012] According to some embodiments of the utility model, the connecting arm is provided with the shaft hole, the ear fork is provided with the mounting position, the rotating shaft mechanism also includes a rotating shaft seat, the rotating shaft seat is arranged in the mounting position and sleeved on the outside of the rotating shaft, and the rotating shaft seat fixes the rotating shaft and the ear fork together.

[0013] According to some embodiments of the present utility model, the rotating shaft seat is in contact with and cooperates with the connecting arm.

[0014] According to some embodiments of the utility model, the shaft seat has a first contact surface arranged perpendicularly to the axis of the shaft, the connecting arm has a second contact surface arranged perpendicularly to the shaft, and the first contact surface is in contact and cooperation with the second contact surface.

[0015] According to some embodiments of the utility model, the rotating shaft seat is provided with a first mounting hole, the rotating shaft is provided with a second mounting hole corresponding to the first mounting hole, the ear fork is provided with a third mounting hole corresponding to the second mounting hole, and the rotating shaft mechanism also includes a fastener passing through the first mounting hole, the second mounting hole and the third mounting hole.

[0016] According to some embodiments of the utility model, the rotating shaft is provided with wire holes penetrating through both ends of the rotating shaft.

[0017] A headset according to an embodiment of the second aspect of the utility model comprises the ear fork assembly as described above.

[0018] The headset according to the embodiment of the utility model has at least the following beneficial effects:

[0019] The headset of the utility model has an ear fork assembly of the above-mentioned embodiment. In the ear fork assembly, the connecting arm is used to connect the headband assembly, the ear fork is connected to the connecting arm by a rotating shaft mechanism, and the ear fork is used to connect the earphone body; the ear fork can rotate relative to the connecting arm, thereby driving the earphone body to rotate to adjust the angle of the earphone body. One end of the rotating shaft is inserted into the installation position and is restricted from escaping from the installation position, and the rotating shaft is rotatably inserted into the shaft hole, so that the ear fork can be rotated relative to the connecting arm by relying on the rotating shaft. In addition, by sleeve-arranging an anti-slipping member at one end of the rotating shaft away from the installation position, the anti-slipping member can be relied on to restrict the rotating shaft from escaping from the shaft hole. In addition, by sleeve-arranging a wear-resistant ring at one end of the rotating shaft away from the installation position, and pressing the anti-slipping member on the wear-resistant ring, when the rotating shaft rotates, the anti-slipping member will be driven to rotate relative to the wear-resistant ring, and a friction effect will be generated between the wear-resistant ring and the anti-slipping member. Among them, a positioning chamfer is provided at the edge of the end of the shaft hole away from the installation position; a positioning bevel is provided on one side of the wear-resistant ring, and the positioning bevel is positioned and matched with the surface of the positioning chamfer, and the anti-slip part is pressed on the side of the wear-resistant ring away from the positioning chamfer. It can be understood that the positioning chamfer is formed by opening a chamfer on the edge of the end of the shaft hole away from the installation position, the entire positioning chamfer is a ring structure, and the surface of the positioning chamfer is inclined. The positioning bevel on the side of the wear-resistant ring close to the installation position is adapted to the surface of the positioning chamfer, so that when the positioning chamfer of the positioning bevel of the wear-resistant ring fits, the positioning chamfer has the effect of centering and positioning the entire wear-resistant ring, which can reduce the risk of the wear-resistant ring being offset in the radial direction of the shaft hole. In this way, the risk of the anti-slip part driving the wear-resistant ring to deviate in the radial direction of the shaft hole when the anti-slip part rotates relative to the wear-resistant ring can be reduced, thereby reducing the risk of the contact area between the anti-slip part and the wear-resistant ring, or the risk of the contact area between the wear-resistant ring and the connecting arm changing, and improving the stability of the ear fork when rotating relative to the connecting arm.

In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0036] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] like Figure 1 As shown, an ear fork assembly provided by the utility model can be applied to a headset, wherein the headset can be a smart headset, and the headset can be configured with a call noise reduction function and / or an artificial intelligence noise reduction function, and at the same time, can also be configured with stereo surround and other functions.

[0038] Combination Figure 1 and Figure 2 The ear fork assembly includes a connecting arm 100, an ear fork 200 and a rotating shaft mechanism 300.

[0039] The connecting arm 100 is used to connect the headband assembly, the ear fork 200 is connected to the connecting arm 100 by means of a rotating shaft mechanism 300, and the ear fork 200 is used to connect the earphone body; the ear fork 200 can rotate relative to the connecting arm 100, thereby driving the earphone body to rotate to adjust the angle of the earphone body.

[0040] Combination Figure 2 and Figure 3 Further, the connecting arm 100 is provided with an axial hole 110, and the ear fork 200 is provided with a mounting position 210 arranged opposite to the axial hole 110. Specifically, the axial hole 110 is arranged at one end of the connecting arm 100 away from the headband assembly, and the mounting position 210 is arranged at the top of the ear fork 200 and arranged opposite to the axial hole 110.

[0041] Combination Figure 3 and Figure 4 The rotating shaft mechanism 300 includes a rotating shaft 310, an anti-slip component 320 and a wear-resistant ring 330. One end of the rotating shaft 310 is arranged at the mounting position 210 and is limited in the mounting position 210, and the rotating shaft 310 is rotatably passed through the shaft hole 110. The wear-resistant ring 330 is sleeved on one end of the rotating shaft 310 away from the mounting position 210. The anti-slip component 320 is sleeved on one end of the rotating shaft 310 away from the mounting position 210 and pressed on the wear-resistant ring 330.

[0042] It can be understood that the mounting position 210 is a mounting groove, and one end of the rotating shaft 310 is inserted into the mounting position 210 and is restricted from being disengaged from the mounting position 210. In addition, the rotating shaft 310 is rotatably inserted into the shaft hole 110, so that the ear fork 200 can be rotated relative to the connecting arm 100 by relying on the rotating shaft 310. In addition, by sleeve-arranging the anti-slipping member 320 at one end of the rotating shaft 310 away from the mounting position 210, the anti-slipping member 320 can be relied on to restrict the rotating shaft 310 from being disengaged from the shaft hole 110. In addition, by sleeve-arranging the wear-resistant ring 330 at one end of the rotating shaft 310 away from the mounting position 210, and pressing the anti-slipping member 320 on the wear-resistant ring 330, when the rotating shaft 310 rotates, the anti-slipping member 320 will be driven to rotate relative to the wear-resistant ring 330, and a friction effect will be generated between the wear-resistant ring 330 and the anti-slipping member 320.

[0043] Combination Figure 3 and Figure 6 Furthermore, a positioning chamfer 111 is provided on the edge of one end of the shaft hole 110 away from the mounting position 210; a positioning inclined surface 331 is provided on one side of the wear-resistant ring 330, and the wear-resistant ring 330 is sleeved on the end of the rotating shaft 310 away from the mounting position 210, and the positioning inclined surface 331 is positioned and matched with the surface of the positioning chamfer 111, and the anti-slip component 320 is sleeved on the end of the rotating shaft 310 away from the mounting position 210, and is pressed on the side of the wear-resistant ring 330 away from the positioning chamfer 111.

[0044] It can be understood that the positioning chamfer 111 is formed by providing a chamfer at the edge of the end of the shaft hole 110 away from the installation position 210, and the entire positioning chamfer 111 is an annular structure, and the surface of the positioning chamfer 111 is inclined. The positioning bevel 331 on the side of the wear ring 330 close to the installation position 210 is adapted to the surface of the positioning chamfer 111, so that when the positioning bevel 331 of the wear ring 330 fits the positioning chamfer 111, the positioning chamfer 111 has the effect of centering the entire wear ring 330, which can reduce the risk of the wear ring 330 being offset in the radial direction of the shaft hole 110. In this way, the risk of the wear-resistant ring 330 being displaced in the radial direction of the axial hole 110 when the anti-slip part 320 rotates relative to the wear-resistant ring 330 can be reduced, thereby reducing the risk of changes in the contact area between the anti-slip part 320 and the wear-resistant ring 330, or the contact area between the wear-resistant ring 330 and the connecting arm 100, thereby improving the stability of the ear fork 200 when rotating relative to the connecting arm 100.

[0045] Combination Figure 6 and Figure 7 Furthermore, the self-positioning inclined surface 331 of the wear-resistant ring 330 is provided with a plurality of avoidance grooves 332 arranged at intervals along the circumference of the wear-resistant ring 330 .

[0046] It is understandable that the provision of the avoidance groove 332 can reduce the contact area between the wear-resistant ring 330 and the positioning chamfer 111 , thereby reducing the friction between the wear-resistant ring 330 and the positioning chamfer 111 .

[0047] Combination Figure 3 and Figure 7 In some embodiments, the wear-resistant ring 330 has a friction surface 333 disposed opposite to the positioning inclined surface 331, and the friction surface 333 is perpendicular to the axis of the rotating shaft 310. The anti-slip component 320 has an extrusion surface disposed perpendicular to the axis of the rotating shaft 310, and the extrusion surface is in contact with the friction surface 333.

[0048] It is understandable that the anti-slip member 320 can squeeze the wear ring 330, thereby achieving the positioning of the wear ring 330. Conversely, the wear ring 330 can also limit the anti-slip member 320, preventing the anti-slip member 320 from moving toward the shaft hole 110 and causing the shaft 310 to loosen. Among them, the friction surface 333 of the wear ring 330 is perpendicular to the axis of the shaft 310 and squeezes and contacts with the extrusion surface of the anti-slip member 320, and the extrusion surface of the anti-slip member 320 is perpendicular to the axis of the shaft 310, so that when the anti-slip member 320 rotates relative to the wear ring 330, the contact area between the anti-slip member 320 and the wear ring 330 remains unchanged, thereby improving the stability of the ear fork 200 when rotating relative to the connecting arm 100.

[0049] Combination Figure 3 , Figure 4 and Figure 5 In some embodiments, the anti-slip member 320 is threadedly connected to the rotating shaft 310, and the anti-slip member 320 can be operably rotated and moved along the axial direction of the rotating shaft 310 to change the preload force between the anti-slip member 320 and the wear ring 330. In this way, by rotating the anti-slip member 320, the preload force between the anti-slip member 320 and the wear ring 330 can be changed, thereby changing the force required to adjust the angle of the ear fork 200.

[0050] Specifically, the anti-slip component 320 is an anti-slip nut, an end of the rotating shaft 310 away from the installation position 210 is provided with an external thread, the anti-slip nut is sleeved on the end of the rotating shaft 310 away from the installation position 210, and the internal thread of the anti-slip nut is connected to the external thread of the rotating shaft 310.

[0051] It should be noted that, in other embodiments, the mounting position 210 may be provided on the connecting arm 100 , and the axial hole 110 may be provided on the ear fork 200 .

[0052] Combination Figure 3 and Figure 4In some embodiments, the connecting arm 100 is provided with an axial hole 110, the ear fork 200 is provided with a mounting position 210, and the rotating shaft mechanism 300 also includes a rotating shaft seat 340, which is arranged in the mounting position 210 and sleeved on the outside of the rotating shaft 310, and the rotating shaft seat 340 fixes the rotating shaft 310 and the ear fork 200 together.

[0053] Specifically, an undercut portion 312 is provided at one end of the rotating shaft 310 close to the mounting position 210 , and the rotating shaft seat 340 is pressed on a side of the undercut portion 312 close to the shaft hole 110 , and the rotating shaft seat 340 is used to limit the undercut portion 312 from escaping from the mounting position 210 .

[0054] Combination Figure 4 and Figure 5 Further, the shaft seat 340 is provided with a first mounting hole 341, the shaft 310 is provided with a second mounting hole 313 corresponding to the first mounting hole 341, the ear fork 200 is provided with a third mounting hole corresponding to the second mounting hole 313, and the shaft mechanism 300 further includes a fastener 350 penetrating the first mounting hole 341, the second mounting hole 313 and the third mounting hole. In this way, under the action of the fastener 350, the shaft seat 340 and the shaft 310 can be fixed to the ear fork 200 together.

[0055] Specifically, the second mounting hole 313 is opened in the undercut portion 312, the first mounting hole 341, the second mounting hole 313 and the third mounting hole are arranged relatively, and the fastener 350 is sequentially passed through the first mounting hole 341, the second mounting hole 313 and the third mounting hole.

[0056] The first mounting hole 341 and the second mounting hole 313 are both through holes, the third mounting hole is a screw hole, and the fastener 350 is a screw.

[0057] Of course, in other embodiments, the shaft seat 340, the shaft 310 and the ear fork 200 may also be fixed together by bonding or welding.

[0058] like Figure 3 As shown, further, the rotating shaft seat 340 is in contact with the connecting arm 100. In this way, when the ear fork 200 rotates relative to the connecting arm 100, friction will also be generated between the rotating shaft seat 340 and the connecting arm 100.

[0059] Specifically, the shaft seat 340 has a first contact surface 342 disposed perpendicularly to the axis of the shaft 310 , and the connecting arm 100 has a second contact surface 120 disposed perpendicularly to the shaft 310 . The first contact surface 342 contacts and cooperates with the second contact surface 120 .

[0060] It can be understood that the first contact surface 342 of the shaft seat 340 is perpendicular to the axis of the shaft 310 and contacts the second contact surface 120 of the connecting arm 100, and the second contact surface 120 of the connecting arm 100 is perpendicular to the axis of the shaft 310. This allows the contact area between the shaft seat 340 and the connecting arm 100 to remain unchanged when the shaft seat 340 rotates relative to the connecting arm 100, thereby improving the stability of the ear fork 200 when it rotates relative to the connecting arm 100.

[0061] Combination Figure 3 , Figure 4 and Figure 5 In some embodiments, the shaft 310 is provided with wire holes 311 penetrating both ends of the shaft 310, and the wire holes 311 are used for passing the signal wire 400, so that the signal wire 400 passes from the inside of the connecting arm 100 to the inside of the ear fork 200. It should be noted that only a part of the signal wire 400 is shown in the figure.

[0062] The utility model also provides a headset having an ear fork assembly of the above embodiment. In the ear fork assembly, the connecting arm 100 is used to connect the headband assembly, the ear fork 200 is connected to the connecting arm 100 by means of a rotating shaft mechanism 300, and the ear fork 200 is used to connect the headphone body; the ear fork 200 can rotate relative to the connecting arm 100, thereby driving the headphone body to rotate to adjust the angle of the headphone body. One end of the rotating shaft 310 is inserted into the mounting position 210 and is restricted from being disengaged from the mounting position 210, and the rotating shaft 310 is rotatably inserted into the shaft hole 110, so that the ear fork 200 can be rotated relative to the connecting arm 100 by means of the rotating shaft 310. In addition, by sleeve-arranging an anti-slipping member 320 at one end of the rotating shaft 310 away from the mounting position 210, the anti-slipping member 320 can be used to restrict the rotating shaft 310 from being disengaged from the shaft hole 110. Furthermore, by sleeve-mounting the wear-resistant ring 330 on the end of the rotating shaft 310 away from the installation position 210, and pressing the anti-slip member 320 on the wear-resistant ring 330, when the rotating shaft 310 rotates, the anti-slip member 320 will be driven to rotate relative to the wear-resistant ring 330, and a friction effect will be generated between the wear-resistant ring 330 and the anti-slip member 320. Among them, the edge of the end of the shaft hole 110 away from the installation position 210 is provided with a positioning chamfer 111; one side of the wear-resistant ring 330 is provided with a positioning bevel 331, and the positioning bevel 331 is positioned and matched with the surface of the positioning chamfer 111, and the anti-slip member 320 is pressed on the side of the wear-resistant ring 330 away from the positioning chamfer 111. It can be understood that the positioning chamfer 111 is formed by providing a chamfer on the edge of the end of the shaft hole 110 away from the installation position 210, and the entire positioning chamfer 111 is a ring structure, and the surface of the positioning chamfer 111 is inclined. The positioning bevel 331 of the wear ring 330 on the side close to the installation position 210 is matched with the surface of the positioning chamfer 111. In this way, when the positioning bevel 331 of the wear ring 330 and the positioning chamfer 111 are in contact, the positioning chamfer 111 has the effect of centering the entire wear ring 330, which can reduce the risk of the wear ring 330 being offset in the radial direction of the shaft hole 110. In this way, the risk of the wear ring 330 being offset in the radial direction of the shaft hole 110 caused by the rotation of the anti-slip member 320 relative to the wear ring 330 can be reduced, thereby reducing the risk of changes in the contact area between the anti-slip member 320 and the wear ring 330, or the contact area between the wear ring 330 and the connecting arm 100, thereby improving the stability of the ear fork 200 when rotating relative to the connecting arm 100.
