When the positioning elastic sheet 3 rotates relative to the rotating shaft 2, the positioning surface 3121 can abut against one of the positioning surfaces 3121.
When the hinge structure for the headset is adopted, if the hinge structure is applied between the headset support and the earcap of the headset, one of the connecting support 1 and the positioning elastic sheet 3 can be connected with the headset support of the headset, the other one of the connecting support 1 and the positioning elastic sheet 3 can be connected with the earcap of the headset, and the positioning elastic sheet 3 rotates relative to the rotating shaft 2, so that the hinge function is realized. In addition, the outer wall of the rotating shaft 2 is provided with the plurality of limiting surfaces 21, the inner wall of the positioning elastic sheet 3 is provided with the positioning surface 3121, and when the positioning elastic sheet 3 rotates relative to the rotating shaft 2, the positioning surface 3121 can be abutted against one of the limiting surfaces 21, so that the purpose of rotation limiting is achieved, and the rotation is suspended at a certain rotation angle. This a hinge structure for headphone's simple structure, the equipment is convenient, only needs a location shell fragment 3 and a pivot 2 just can realize the function of headphone's hinge, and the packaging stability is high and packaging efficiency is high.
It should be noted that, in the embodiment of the present invention, the hinge structure for the headset is only applied between the headset holder and the earcap as an example. When in application, the hinge structure for the headset is not limited to be connected between the headset bracket and the earcap, but also can be connected to other positions of the headset where the hinge structure needs to be hinged, and the connection is not limited to this.
In an embodiment, as shown in fig. 6 and 7, the plurality of limiting surfaces 21 are disposed on the outer wall of the rotating shaft 2 at intervals along the circumferential direction of the rotating shaft 2, and the limiting surfaces 21 are disposed continuously and uninterruptedly along the axial direction of the rotating shaft 2, that is, the limiting surfaces 21 are a continuous complete plane along the axial direction of the rotating shaft 2. In practical applications, the area of the limiting surface 21 can be increased as much as possible, so as to increase the contact area between the limiting surface 21 and the positioning surface 3112, and to better limit the rotation of the hinge structure.
In other embodiments not shown in the drawings, the limiting surfaces may also be disposed discontinuously and at intervals along the axial direction of the rotating shaft, that is, the limiting surfaces may be formed by a plurality of limiting facets arranged at intervals along the axial direction of the rotating shaft, so as to effectively prevent relative displacement (i.e., sliding displacement) between the positioning surface and the limiting surfaces along the axial direction of the rotating shaft, and avoid the occurrence of part dislocation.
In an embodiment, as shown in fig. 6 and 7, in the circumferential direction of the rotating shaft 2, two adjacent limiting surfaces 21 are perpendicular to each other. In the illustrated embodiment, the outer wall of the rotating shaft 2 is provided with two limiting surfaces 21 arranged in a circumferential direction of the rotating shaft 2. It can be understood that, when the positioning elastic sheet 3 rotates relative to the rotating shaft 2, the positioning surface 3121 moves from the originally contacted limiting surface 21 to another limiting surface 21, and contacts with another limiting surface 21, thereby realizing the positioning after the positioning elastic sheet 3 rotates relative to the rotating shaft 2. Furthermore, because two adjacent limiting surfaces 21 are perpendicular to each other, that is, the positioning elastic sheet 3 can rotate 90 degrees relative to the rotating shaft 2 and then is limited by the other limiting surface 21.
In other embodiments not shown in the drawings, in the circumferential direction of the rotating shaft, an included angle between two adjacent limiting surfaces may also be set to other degrees, such as 30 °, 50 °, 100 °, or 130 °, according to actual needs, and correspondingly, when the positioning surface moves from the originally contacted limiting surface to another adjacent limiting surface and contacts with the other adjacent limiting surface, the rotation angle of the positioning elastic piece relative to the rotating shaft is the included angle between two adjacent limiting surfaces.
In addition, in other embodiments not shown in the drawings, in the circumferential direction of the rotating shaft, the included angles between two adjacent limiting surfaces may be the same, may also be different, or may also be partially the same and partially different. Specifically, taking the rotating shaft is provided with three limiting surfaces as an example, three limiting surfaces are respectively set as a first limiting surface, a second limiting surface and a third limiting surface, wherein the included angle between the first limiting surface and the second limiting surface is a first included angle, the included angle between the second limiting surface and the third limiting surface is a second included angle, the included angle between the first limiting surface and the third limiting surface is a third included angle, when the included angles are set, the angle of the first included angle, the angle of the second included angle and the angle of the third included angle are the same (namely, the included angles are the same in degree), the angle of the first included angle, the angle of the second included angle and the angle of the third included angle are different (namely, the included angles are different in degree), or the angle of the first included angle and the angle of the second included angle are the same and the angle of the second included angle and the angle of the third included angle are different (namely, the included angles are different in degree), or the angle of the first included angle and the angle of the second included angle and the third included angle are different in degree The degrees of each angle are partially the same and partially different). The specific setting can be adjusted according to actual needs, and is not limited herein.
In an embodiment, as shown in fig. 6 and 7, the limiting surface 21 is formed by recessing the outer wall of the rotating shaft 2 toward the axis of the rotating shaft 2, and the limiting surface 21 is rectangular. It can be understood that the rotating shaft 2 forms a stepped structure at the edge of the limiting surface 21 due to the recess, and when the positioning surface 3121 abuts against the limiting surface 21 for limiting, the stepped structure limits the positioning surface 3121, so as to prevent the positioning surface 3121 from sliding relative to the limiting surface 21 along the axial direction of the rotating shaft 2, further prevent the positioning elastic sheet 3 from displacing relative to the rotating shaft 2 along the axial direction of the rotating shaft 2, and avoid the phenomenon of part dislocation.
In an embodiment, as shown in fig. 4 and 5 and fig. 6 and 7, the limiting surface 21 is a plane, and correspondingly, in order to achieve effective contact between the positioning surface 3121 and the limiting surface 21, the positioning surface 3121 is also configured as a plane.
In other embodiments not shown in the drawings, the position-limiting surface may also be configured as a non-planar structure, such as an arc surface, a frosted surface or an uneven surface, and correspondingly, the positioning surface will also be adapted to the position-limiting surface, that is, the positioning surface will also be a non-planar structure, such as an arc surface, a frosted surface or an uneven surface adapted to the position-limiting surface. Through with spacing face reaches the locating surface all sets up to non-planar structure, multiplicable spacing face with frictional force between the locating surface to reinforcing spacing face with rotation spacing effect when the locating surface butt prevents the locating surface is relative spacing face takes place to deflect.
In an embodiment, as shown in fig. 4 and 5, the positioning elastic sheet 3 includes a positioning main body 31 and a positioning arm 32, the positioning main body 31 is an annular structure with a lateral opening, the positioning arm 32 is connected to an end of the positioning main body 31 at the opening, the positioning main body 31 is sleeved on the rotating shaft 2, and the inner wall of the positioning main body 31 is provided with the positioning surface 3121.
When the hinge structure is used at a position of a headset to be hinged, the hinge structure can be connected with a part of the headset through the positioning arm 32 of the positioning elastic sheet 3, so that the hinge structure is mounted at the position of the positioning elastic sheet 3.
Further, the positioning arm 32 is provided with a plurality of positioning holes 321, and the positioning arm 32 can be connected with a part of the headset through the positioning holes 321. Preferably, the positioning arm 32 can be screwed with a part of the headset by passing through the positioning hole 321 through a screw, or a clamping member adapted to the positioning hole 321 on the part of the headset can be clamped in the positioning hole 321 to be connected in a clamping manner. In addition, the positioning arm 32 may be glued or otherwise connected to the headset part.
In one embodiment, as shown in fig. 4 and 5, the positioning main body 31 includes a surrounding portion 311 and a positioning portion 312, the surrounding portion 311 is connected between the positioning arm 32 and the positioning portion 312, the inner wall of the positioning portion 312 is provided with the positioning surface 3121, and the inner wall of the surrounding portion 311 is provided with an arc surface 3111 connected to the positioning surface 3121.
It can be understood that when the positioning elastic sheet 3 rotates relative to the rotating shaft 2, the positioning arm 32 drives the surrounding portion 311 to rotate relative to the rotating shaft 2, so as to drive the positioning portion 312 to rotate relative to the rotating shaft 2, so that the positioning surface 3121 on the positioning portion 312 moves from the originally contacted limiting surface 21 to another limiting surface 21 and abuts against the other limiting surface 21, thereby achieving the rotation limiting of the positioning elastic sheet 3.
Further, because the inner wall of the surrounding part 311 is provided with the arc surface 3111, it is reducible the surrounding part 311 with friction between the pivot 2 is more convenient for the rotation of the positioning elastic sheet 3, and the arc surface 3111 can be laminated with the outer wall of the pivot 2, better make the positioning elastic sheet 3 only follow the axis of the pivot 2 is rotatory, prevent that the positioning elastic sheet 3 deflects, simultaneously can make the positioning surface 3121 with the laminating between the spacing surface 21 is inseparabler, improves and rotates spacing effect.
It can be understood that, in order to make the arc-shaped surface 3111 better fit with the outer wall of the rotating shaft 2, the lateral opening of the positioning main body 31 can be reduced as much as possible, so as to reduce the deformation amount of the positioning elastic sheet 3 during rotation, so that the positioning elastic sheet 3 only rotates along the axis of the rotating shaft 2, prevent the positioning elastic sheet 3 from deflecting or separating from the rotating shaft 2, and make the fit between the positioning surface 3121 and the limiting surface 21 tighter, thereby improving the effect of rotation limitation.
In an embodiment, as shown in fig. 4 and 5, the plane where the positioning arm 32 is located is parallel to the positioning surface 3121, so as to reduce the deformation amount when the positioning elastic sheet 3 rotates, so that the positioning elastic sheet 3 only rotates along the axis of the rotating shaft 2, and the plane where the positioning arm 32 is located is always parallel to the positioning surface 3121, thereby preventing the positioning elastic sheet 3 from deflecting or separating from the rotating shaft 2, and simultaneously making the joint between the positioning surface 3121 and the limiting surface 21 tighter, and improving the effect of rotation limiting.
In other embodiments not shown in the drawings, an included angle between the plane where the positioning arm is located and the positioning surface may also be adjusted according to actual needs, as long as it is ensured that the deformation amount of the positioning elastic piece is small when the positioning elastic piece rotates, so as to prevent the positioning elastic piece from deflecting or separating from the rotating shaft.
In an embodiment, as shown in fig. 4 and 5, an arc-shaped connecting surface is formed at a position where the positioning main body 31 is connected to the positioning arm 32, and the arrangement of the arc-shaped connecting surface can reduce friction between the positioning elastic sheet 3 and the rotating shaft 2, thereby reducing wear of the positioning elastic sheet 3 and the rotating shaft 2 and increasing service lives of the positioning elastic sheet 3 and the rotating shaft 2.
In an embodiment, as shown in fig. 4 and 5, a lightening hole 33 is formed at a position where the positioning main body 31 is connected to the positioning arm 32, so as to lighten the total amount of the positioning elastic sheet 3, and at the same time, lighten the overall weight of the hinge structure, and reduce the overall weight of the headset as little as possible.
In an embodiment, as shown in fig. 2 and 8, the connecting bracket 1 is provided with a non-circular insertion hole 111, an insertion block 22 having a shape adapted to the shape of the fastening hole 111 is provided at an end of the rotating shaft 2, and the insertion block 22 is inserted into the insertion hole 111 to complete the connection between the rotating shaft 2 and the connecting bracket 1.
It can be understood that, because the insertion hole 111 is non-circular, when the rotating shaft 2 is connected to the connecting bracket 1 through the insertion block 22, the rotating shaft 2 cannot rotate relative to the connecting bracket 1, so as to prevent the positioning elastic sheet 3 from rotating relative to the rotating shaft 2, prevent the connecting bracket 1 and the positioning elastic sheet 3 from rotating relative to the rotating shaft 2 at the same time, and thus achieve effective positioning of rotation.
In an embodiment, as shown in fig. 8, the connecting bracket 1 includes a connecting main body 11 and a connecting arm 12 connected to the connecting main body 11, and the connecting main body 11 is provided with the inserting hole 111.
