[0002] To reduce their size and facilitate storage, headphones often feature a foldable design with a hinge. However, current headphone hinges cannot lock themselves in certain positions to prevent the headphones from rotating uncontrollably, resulting in a poor user experience. Therefore, this problem urgently needs to be solved. Summary of the Invention

[0003] This application provides a rotating shaft, which includes a first hinge, a second hinge, and a positioning component. The first hinge includes a first connecting portion; the second hinge includes a second connecting portion, which is rotatably connected to the first connecting portion, and the second connecting portion is provided with a positioning groove. The positioning component includes an elastic member and a snap-fit ​​member. One end of the elastic member is connected to the first hinge, and the snap-fit ​​member is disposed at the end of the elastic member away from the first hinge. The elastic extension and contraction direction of the elastic member is perpendicular to the rotation axis direction of the second connecting portion, and the elastic member elastically holds the snap-fit ​​member against the second connecting portion. During the rotation of the second connecting portion, the snap-fit ​​member can move into the positioning groove and can also move out of the positioning groove.

[0004] Optionally, in some embodiments, there are two first connecting parts, which are spaced apart along a first direction; there are two second connecting parts, which are respectively located on opposite sides of the two first connecting parts; the rotating shaft also includes two connectors, which are used to connect the first connecting parts and the second connecting parts.

[0005] Optionally, in some embodiments, the first hinge further includes a first main body, a first connecting part connected to the first main body, a limiting groove provided on the first main body, the extending direction of the limiting groove being perpendicular to the rotation axis direction of the second connecting part, and an elastic element disposed in the limiting groove.

[0006] Optionally, in some embodiments, a first wiring channel is provided on the first main body, the first wiring channel is located between two first connecting parts, and the first wiring channel passes through the first main body along a second direction.

[0007] Optionally, in some embodiments, the second hinge further includes a second main body portion, and the second connecting portion is connected to the second main body portion; a second wiring channel is provided on the second main body portion, the second wiring channel is located between the two second connecting portions, and the second wiring channel passes through the second main body portion along a second direction.

[0008] Optionally, in some embodiments, the port of the first wiring channel near the end of the second hinge is positioned opposite to the port of the second wiring channel near the end of the first hinge.

[0009] Optionally, in some embodiments, the shaft further includes a gasket, and the second connecting portion is provided with a mounting groove on the side opposite to the first connecting portion. The gasket is embedded in the mounting groove, and the connector is provided on the side of the second connecting portion opposite to the first connecting portion. At least a portion of the structure of the connector is accommodated in the mounting groove and presses the gasket against the bottom surface of the mounting groove.

[0012] Optionally, in some embodiments, multiple positioning grooves are provided on the second connecting portion, and the multiple positioning grooves are spaced apart from each other.

[0013] In the rotating shaft provided in this embodiment, due to the presence of a positioning component and a positioning groove, the positioning groove continuously moves along with the second connecting part during the rotation of the shaft. When the locking member moves into the positioning groove, the elastic member elastically holds the locking member against the bottom of the positioning groove, thereby forming a locking structure between the locking member and the positioning groove, thus restricting the rotation of the shaft. When the user needs to release the locking effect of the locking member on the rotating shaft, they only need to forcefully rotate the first hinge and the second hinge to move the locking member out of the positioning groove, which is simple and convenient to operate. The specific position of the positioning groove on the second connecting part can be calculated and designed in advance according to the usage requirements to meet the diverse usage needs of users. In summary, the above-mentioned rotating shaft can meet the user's need to lock the rotating shaft in a specific position, and the overall structure is simple and easy to use.

[0023] Please see Figures 1 to 3 This application provides a hinge 100, which can be used to achieve a rotatable connection between two objects. As a specific example, the hinge 100 can be applied to a foldable headset to achieve a rotatable connection between the two parts of the headset body, thereby realizing the folding function of the headset body for convenient carrying or storage. In other embodiments, the hinge 100 can also be applied to any other device or component capable of achieving a folding or rotating effect, without limitation.

[0024] Please see Figure 1 and Figure 2 The aforementioned pivot 100 includes a first hinge 10, a second hinge 11, and a positioning assembly 12. The first hinge 10 is a part of the pivot 100 and is used to fix it to the first of two objects that need to be rotated together. The second hinge 11 is a part of the pivot 100 and is used to fix it to the second of two objects that need to be rotated together.

[0025] The first hinge 10 includes a first connecting portion 101, which is a part of the structure of the first hinge 10. As a specific example, in this embodiment, the first connecting portion 101 is generally disc-shaped. The second hinge 11 includes a second connecting portion 111, which is a part of the structure of the second hinge 11. As a specific example, in this embodiment, the second connecting portion 111 is generally disc-shaped. The second connecting portion 111 is rotatably connected to the first connecting portion 101, and a positioning groove 113 is provided on the second connecting portion 111. The second connecting portion 111 and the first connecting portion 101 are coaxially arranged, and the rotation axis 100 of the second connecting portion 111 and the first connecting portion 101 is in the same direction. Figure 1 The direction indicated by the middle arrow X. The positioning assembly 12 includes an elastic element 121 and a snap-fit ​​element 122. The elastic element 121 itself can elastically extend and retract, and one end of the elastic element 121 is connected to the first hinge 10. The snap-fit ​​element 122 is used to snap into the positioning groove 113 to lock the rotating shaft 100. The snap-fit ​​element 122 is located at the end of the elastic element 121 away from the first hinge 10. It should be noted that the snap-fit ​​element 122 can be connected to the elastic element 121, or it can simply contact the elastic element 121 without any connection relationship; this is not limited. The elastic extension and retraction direction of the elastic element 121 is the same as the direction of the rotating shaft 100 of the second connecting part 111 (i.e., Figure 1 (The direction indicated by the middle arrow X) is perpendicular. The elastic member 121 elastically holds the snap-fit ​​member 122 against the second connecting part 111. During the rotation of the second connecting part 111, the snap-fit ​​member 122 can move into the positioning groove 113 and can also move out of the positioning groove 113.

[0026] With the above configuration, during the rotation of the shaft 100, since the positioning groove 113 is located on the second connecting part 111 and the positioning component 12 is located on the first connecting part 101, when the second connecting part 111 rotates relative to the first connecting part 101, the positioning component 12 and the positioning groove 113 will move relative to each other. When the positioning groove 113 moves to the position of the snap-fit ​​member 122, the elastic member 121 will push the snap-fit ​​member 122 into the positioning groove 113 due to the elastic force, thereby forming a snap-fit ​​structure between the snap-fit ​​member 122 and the positioning groove 113, thus restricting the shaft 100 from rotating freely. When the user needs to release the locking effect of the snap-fit ​​member 122 on the shaft 100, they only need to forcefully rotate the first hinge 10 and the second hinge 11 to make the snap-fit ​​member 122 move out of the positioning groove 113 due to external force. The operation is simple and convenient. The specific position of the positioning groove 113 on the second connecting part 111 can be calculated and designed in advance according to the usage requirements to meet the diverse usage needs of users. In summary, the aforementioned pivot 100 can meet the user's need to lock the pivot 100 in a specific position, and its overall structure is simple and easy to use.

[0027] In this embodiment, as a specific example, the elastic element 121 is a spring, and the snap-fit ​​element 122 is a spherical element. Because the snap-fit ​​element 122 is spherical, it experiences less friction during contact with and movement relative to the second connecting portion 111, thus not excessively hindering the rotation of the shaft 100. Furthermore, by selecting a spring capable of generating an appropriate amount of elastic force, the friction between the snap-fit ​​element 122 and the second connecting portion 111 provides appropriate damping for the rotation of the shaft 100, preventing excessive looseness during rotation and avoiding a poor user experience. In other embodiments, the elastic element 121 can be any other stretchable and elastic component, and the snap-fit ​​element 122 can be any other structural component of any shape; there is no limitation on this.

[0028] Please see Figure 1 and Figure 2 In some embodiments, two first connecting portions 101 are provided, and the two first connecting portions 101 are along a first direction (i.e. Figure 1 (In the direction indicated by the middle arrow X) spaced apart. Two second connecting portions 111 are provided, each located on a side opposite to the two first connecting portions 101. The rotating shaft 100 also includes two connectors 13, which connect the first connecting portions 101 and the second connecting portions 111. As a specific example, in this embodiment, the connector 13 is specifically a screw, with the shank passing through the second connecting portion 111 along a first direction and threadedly connected to the first connecting portion 101, thereby preventing accidental separation of the first connecting portion 101 and the second connecting portion 111, ensuring a stable rotational connection between them.

[0029] With the above configuration, since there are two of each of the first connecting part 101 and the second connecting part 111, and the two first connecting parts 101 are rotatably connected to the two second connecting parts 111 respectively, it can be ensured that the first hinge 10 and the second adhesive are stably rotatably connected, and the possibility of the first hinge 10 and the second hinge 11 being disconnected due to accident can be avoided as much as possible, which is safe and reliable.

[0030] In some embodiments, two sets of positioning components 12 are provided, and the two sets of positioning components 12 are respectively corresponding to the two second connecting parts 111. With the above arrangement, the two positioning components 12 can lock and position the two second connecting parts 111 individually, which can effectively improve the locking and positioning effect of the positioning components 12 on the rotating shaft 100, reduce the possibility of the positioning components 12 failing to lock the rotating shaft 100, and make the self-locking effect of the rotating shaft 100 more reliable and stable.

[0031] In some embodiments, the first hinge 10 further includes a first main body portion 102. The first main body portion 102 is the main structure of the first hinge 10 and is also the specific structure for fixing the first hinge 10 to the first of two objects that need to be rotatably connected. In this embodiment, the specific shape of the first main body portion 102 is not limited. The first connecting portion 101 is connected to the first main body portion 102. The first main body portion 102 is provided with a limiting groove 103. The extending direction of the limiting groove 103 is perpendicular to the direction of the rotation axis 100 of the second connecting portion 111. An elastic member 121 is disposed in the limiting groove 103 and contacts the inner sidewall of the limiting groove 103. It should be noted that the extending direction of the limiting groove 103 can be understood as the length direction of the limiting groove 103.

[0032] With the above configuration, since the elastic member 121 is located in the limiting groove 103 and contacts the inner wall of the limiting groove 103, and the extension direction of the limiting groove 103 is perpendicular to the direction of the rotating shaft 100 of the second connecting part 111, when the elastic member 121 moves in extension and retraction, the limiting groove 103 can limit and guide the extension and retraction direction of the elastic member 121, so as to ensure that the elastic member 121 can only move in extension and retraction in a direction perpendicular to the direction of the rotating shaft 100 of the second connecting part 111, thereby avoiding the elastic member 121 from affecting the snap-fit ​​engagement between the snap-fit ​​member 122 and the positioning groove 113 due to its own skewed extension and retraction direction. That is, it can be ensured that the positioning component 12 can stably lock the rotating shaft 100 and unlock the rotating shaft 100.

[0033] In some embodiments, a first wiring channel 104 is provided on the first main body 102. The first wiring channel 104 is located between two first connecting portions 101, and the first wiring channel 104 is along a second direction (i.e., Figure 1 The direction indicated by the middle arrow Y) penetrates through the first main body 102. As a specific example, in this embodiment, the second direction is perpendicular to the first direction. In other embodiments, the second direction may not be perpendicular to the first direction, and this is not limited.

[0034] With the above configuration, since the first main body 102 is provided with a first wiring channel 104, when the hinge 100 is applied to electronic devices (such as headphones, tablets, etc.), the electronic device's own wiring can pass through the first wiring channel 104 for wiring when passing through the first hinge 10. This can indirectly reduce the space required to install the hinge 100, which is beneficial to reducing the size of electronic devices using the hinge 100. In addition, the first wiring channel 104 can also protect and guide the wiring, which is beneficial to improving the stability of the wiring and extending the life of the electronic device.

[0035] In some embodiments, the second hinge 11 further includes a second main body 112. The second main body 112 is the main structure of the second hinge 11 and is also a specific structure for fixing the second hinge 11 to the second of two objects that need to be rotatably connected. This embodiment does not limit the specific form of the second main body 112. A second connecting part 111 is connected to the second main body 112. A second wiring channel 114 is provided on the second main body 112. The second wiring channel 114 is located between the two second connecting parts 111 and runs along a second direction (i.e.,...). Figure 1 The direction indicated by the middle arrow Y) penetrates through the second main body 112.

[0036] With the above configuration, since the second main body 112 is provided with a second wiring channel 114, when the hinge 100 is applied to electronic devices (such as headphones, tablets, etc.), the electronic device's own wiring can pass through the second wiring channel when passing the second hinge 11, which can indirectly reduce the space required to install the hinge 100, which is beneficial to reduce the size of electronic devices using the hinge 100. In addition, the second wiring channel 114 can also protect and guide the wiring, which is beneficial to improve the stability of the wiring and extend the life of the electronic device.

[0037] In some embodiments, the port of the first wiring channel 104 near the end of the second hinge 11 is disposed opposite to the port of the second wiring channel 114 near the end of the first hinge 10. With the above arrangement, when the hinge 100 is applied to an electronic device (e.g., headphones, tablet computer, etc.), the electronic device's own wiring can pass through the first wiring channel 104 and the second wiring channel 114 almost in a straight line along the second direction when passing through the first hinge 10 and the second hinge 11, and the bending of the hinge 100 will not affect the extension of the wiring. Therefore, it is not only beneficial to reduce the size of the electronic device using the above-mentioned hinge 100, but also beneficial to improve the stability of the wiring and extend the life of the electronic device.

[0038] In some embodiments, the rotating shaft 100 further includes a gasket 14, which may be a sheet structure made of a soft or hard material, such as polyoxymethylene material or metal material. A mounting groove 115 is provided on the side of the second connecting portion 111 opposite to the first connecting portion 101, and the gasket 14 is embedded in the mounting groove 115. A connector 13 is disposed on the side of the second connecting portion 111 opposite to the first connecting portion 101, and at least a portion of the connector 13 is accommodated in the mounting groove 115 and presses the gasket 14 against the bottom surface of the mounting groove 115.

[0039] With the above configuration, since at least a portion of the connector 13 is housed within the mounting groove 115 and presses the gasket 14 against the bottom surface of the mounting groove 115, when the shaft 100 rotates, the second connection portion 111 rotates relative to the first connection and experiences frictional resistance generated by the gasket 14. This provides damping for the shaft 100, preventing it from rotating easily. Furthermore, the user can change the degree of damping generated when the shaft 100 rotates by adjusting the tightness of the connector 13, thus meeting a wide range of user needs.

[0040] In some embodiments, multiple positioning slots 113 are provided on the second connecting portion 111, and the multiple positioning slots 113 are spaced apart from each other. Through this arrangement, the multiple positioning slots 113 can cooperate with the latching member 122 to lock and position the rotating shaft 100 at multiple different positions, thereby meeting diverse user needs. The specific positions of the positioning slots 113 can be calculated in advance according to product requirements. For example, when the rotating shaft 100 is applied to foldable headphones, a positioning slot 113 can be provided at the position where the latching member 122 contacts the second connecting portion 111 after the two rotating parts of the headphones are fully folded, and another positioning slot 113 can be provided at the position where the latching member 122 contacts the second connecting portion 111 after the two rotating parts of the headphones are fully unfolded. This allows the rotating shaft 100 to be locked after the headphones are fully folded, and also locks the headphones after they are fully opened, thereby improving the user experience when using the headphones.

[0041] In summary, the embodiments of this application provide a rotating shaft 100. Since the rotating shaft 100 is equipped with a positioning component 12 and a positioning groove 113, during the rotation of the rotating shaft 100, the positioning groove 113 continuously moves along with the second connecting part 111. When the locking member 122 moves into the positioning groove 113, the elastic member 121 elastically holds the locking member 122 against the bottom of the positioning groove 113, thereby forming a locking structure between the locking member 122 and the positioning groove 113, thus restricting the free rotation of the rotating shaft 100. When the user needs to release the locking effect of the locking member 122 on the rotating shaft 100, they only need to forcefully rotate the first hinge 10 and the second hinge 11 to move the locking member 122 out of the positioning groove 113. The operation is simple and convenient. The specific position of the positioning groove 113 on the second connecting part 111 can be calculated and designed in advance according to usage requirements to meet diverse user needs. In summary, the aforementioned pivot 100 can meet the user's need to lock the pivot 100 in a specific position, and its overall structure is simple and easy to use.
