Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of glasses of the present application. In this embodiment, the glasses include: spectacle frame 10 and functional piece 20.

The spectacle frame 10 in the present application may be a spectacle frame of various glasses such as a near-view mirror, a far-view mirror, a sunglass, an intelligent glasses, a virtual reality glasses, a holographic glasses, and an augmented reality glasses, and is not particularly limited.

The functional element 20 may be an assembly or component that is connected to the eyeglass frame 10 to provide the eyeglass with further functionality. For example, the functional element 20 may be a speaker mechanism, in particular a bone conduction speaker mechanism 21, so that the glasses also have the function of the bone conduction speaker mechanism 21. Of course, the functional element may be other components, such as a positioning device, etc., which are not limited herein.

Specifically, the eyeglass frame 10 includes an eyeglass frame 11 and two temples 12, and the temples 12 include a temple body 121 connected with the eyeglass frame 11 and a hinge assembly 122.

Referring further to fig. 2 and 3, fig. 2 is a schematic structural view of an embodiment of the hinge assembly of the present application, and fig. 3 is a schematic exploded structural view of an embodiment of the hinge assembly of the present application. Among other things, the hinge assembly 122 of the present application may be used in eyeglasses in the eyeglass embodiments of the present application.

In this application, hinge assembly 122 includes hinge 30, hinge 30 being a structure that connects two solids and allows relative rotation between the two.

Specifically, when the hinge assembly 122 in the present embodiment is used in the above-described eyeglass embodiment, the hinge assembly 122 is provided at the end of the temple body 121 remote from the eyeglass frame 11, and further connects the functional piece 20 to the end of the temple body 121 remote from the eyeglass frame 11 through the hinge 30.

The hinge assembly 122 further includes a rod member 40 and a fixing member 50. The hinge 30 comprises a hinge base 31 and a hinge arm 32, wherein the hinge arm 32 is rotatably connected with the hinge base 31 through a rotation shaft 33. It will be readily appreciated that the hinge mount 31 and the hinge arm 32 may be connected to two members that require rotational connection, respectively, such that the two members are rotationally connected together by the rotational axis 33 of the hinge 30.

Wherein the hinge seat 31 of the hinge 30 is connected to the rod 40. The rod 40 may be a part or an integral structure of one of the two members rotatably connected by the hinge 30, or may be a connection structure of one of the two members to be rotatably connected to the hinge 30. When the hinge assembly 122 of the present embodiment is used for glasses, the rod 40 may be at least a part of the temple body 121 of the glasses, for example, may be the entire temple body 121, or may be a part of an end of the temple body 121 away from the glasses frame 11, and further, the hinge 30 is provided at an end of the temple body 121 away from the glasses frame 11 through the part of the temple body 121.

Specifically, the rod 40 is provided with a hinge cavity 41 communicating with an end surface of the rod 40 in the longitudinal direction, a first insertion hole 42 communicating with the hinge cavity 41 is provided on a side wall of the rod 40, and an end of the hinge base 31 remote from the hinge arm 32 is inserted into the hinge cavity 41 from the end surface of the rod 40 and is fixed in the hinge cavity 41 by a fixing member 50 inserted in the first insertion hole 42.

In the present embodiment, the hinge cavity 41 communicates with the end surface of the temple body 121 remote from the end of the eyeglass frame 11, so that the hinge base 31 is inserted into the hinge cavity 41 to connect the hinge 30 and the temple body 121.

The hinge cavity 41 may be formed during the molding process of the rod 40, for example, the rod 40 may be made of rubber or plastic, and the hinge cavity 41 may be formed by injection molding. The shape of the hinge cavity 41 matches the hinge base 31 so that the hinge base 31 can be accommodated in the hinge cavity 41. In this embodiment, the temple body 121 may be a long rod along the length direction, correspondingly, the rod-shaped member 40 may be a straight rod along the length direction, the hinge cavity 41 is disposed in the straight rod, and further, the hinge seat 31 is matched with the hinge cavity 41 to be accommodated in the hinge cavity 41 so as to realize the installation of the hinge 30. Of course, in other embodiments, the rod 40 may be in other shapes such as an arcuate rod.

In addition, the first insertion hole 42 may be formed by the rod 40 during the molding process, or may be further formed on the side wall of the rod by drilling or the like after the molding process. Specifically, in the present embodiment, the shape of the first insertion hole 42 may be a circle, and in other embodiments, may be a square, a triangle, or the like. The fixing member 50 is shaped to match the first insertion hole 42 so that the fixing member 50 can be inserted into the first insertion hole 42 from the outside of the rod-like member 40, and thereby the hinge base 31 is fixed in the hinge cavity 41 by abutting against the side wall of the hinge base 31, or by penetrating further through the outer wall of the hinge base 31 to be inserted, or the like. Specifically, mating threads may be provided on the inner wall of the first insertion hole 42 and the outer wall of the fixing member 50 to enable the fixing member 50 to be connected with the first insertion hole 42 by screwing to further fix the hinge seat 31 within the hinge cavity 41. Of course, the connection may be made by other means, such as by an interference fit of the first insertion hole 42 with the fixture 50, or the like.

Further, the hinge arm 32 may be connected to other members such that the members are rotatable about the rotational axis 33 after the hinge arm 32 is connected, further by mounting the hinge mount 31 within the hinge cavity 41 of the shaft 40 to be rotatable with the shaft 40 or other members connected to the shaft 40. For example, when the hinge assembly 122 is applied to the above-mentioned glasses, the functional member 20 such as the bone conduction speaker mechanism 21 is connected to the end of the hinge arm 32 away from the hinge base 31, and thus is connected to the end of the temple body 121 away from the glasses frame 11 through the hinge 30.

In the above manner, the hinge cavity 41 communicating with the end surface of the rod 40 is provided on the rod 40, and the hinge 30 is configured such that the hinge seat 31 is accommodated in the hinge cavity 41, and the fixing member 50 is further inserted through the side wall of the rod 40 through the first insertion hole 42, so that the hinge seat 31 accommodated in the hinge cavity 41 is fixed in the hinge cavity 41, thereby enabling the hinge 30 to be detachable with respect to the rod 40, so as to facilitate replacement of the hinge 30 or the rod 40. When applied to the glasses in the above-described glasses embodiments of the present application, the hinge 30 and the functional element 20 can be detachable from the temple body 121, so that replacement is facilitated when the functional element 20, the glasses frame 11, the temple body 121, or the like is damaged.

Further, referring to fig. 3, in an embodiment, the hinge base 31 is provided with a second insertion hole 311 corresponding to the first insertion hole 42, and the fixing member 50 is further inserted into the second insertion hole 311.

Specifically, the shape of the second insertion hole 311 is matched with the fixing member 50 such that the fixing member 50 is further inserted into the second insertion hole 311 after passing through the first insertion hole 42 to fix the hinge base 31, thereby reducing the shaking of the hinge base 31 within the hinge cavity 41, so that the hinge 30 is more firmly fixed. Specifically, similar to the connection manner of the first insertion hole 42 and the fixing member 50, the inner sidewall of the second insertion hole 311 may be provided with threads matched with each other on the outer wall corresponding to the fixing member 50, so that the fixing member 50 is screwed with the hinge seat 31; alternatively, the outer side walls of the positions where the inner walls of the second insertion holes 311 and the fixing members 50 are in corresponding contact are smooth surfaces, and the fixing members 50 are in interference fit with the second insertion holes 311, which is not particularly limited herein.

Further, the second insertion holes 311 may also penetrate through both sides of the hinge base 31, so that the fixing member 50 can penetrate through the whole hinge base 31 to fix the hinge base 31 in the hinge cavity 41 more firmly.

With further reference to fig. 4, fig. 4 is a cross-sectional view of the hinge assembly 122 of fig. 2 along the A-A axis. In the present embodiment, the cross-sectional shape of the hinge mount 31 matches the cross-sectional shape of the hinge cavity 41 in a cross-section perpendicular to the length direction of the rod 40 so that a sealing fit is formed between the hinge mount 31 and the rod 40 after insertion.

In the cross section shown in fig. 4, the cross-sectional shape of the hinge mount 31 and the cross-sectional shape of the hinge cavity 41 may be any shape as long as the hinge mount 31 can be inserted into the hinge cavity 41 from the end surface of the rod 40 away from the hinge arm 32. Further, a first insertion hole 42 is provided on a side wall of the hinge chamber 41 and communicates with the hinge chamber 41 through the side wall of the hinge chamber 41.

In one application scenario, the cross-sectional shape of the hinge seat 31 and the cross-sectional shape of the hinge cavity 41 are both rectangular, and the first insertion hole 42 is perpendicular to one side of the rectangle.

Specifically, in the present application scenario, the corner angle of the outer side wall of the hinge seat 31 or the corner rounding angle of the inner side wall of the hinge cavity 41 may be further set, so that the contact between the hinge seat 31 and the hinge cavity 41 is smoother, and the hinge seat 31 can be smoothly inserted into the hinge cavity 41.

It should be further noted that a certain amount of gas is stored in the hinge cavity 41 before the assembly of the hinge 30, so if the hinge cavity 41 is only a cavity with one end opened, the insertion of the hinge base 31 will be impaired due to the difficulty in exhausting the gas in the hinge cavity 41 during the assembly process, thereby affecting the assembly. The first insertion hole 42 in the present embodiment penetrates through the sidewall of the hinge chamber 41 to communicate with the hinge chamber 41, and can assist in discharging the gas inside through the hinge chamber 41 from the first insertion hole 42 during the assembly process, thereby facilitating the normal assembly of the hinge 30.

With further reference to fig. 5, fig. 5 is a schematic structural view of an embodiment of a hinge assembly according to the present application. In the hinge assembly 122 embodiment of the present application, the hinge assembly 122 further includes a connecting wire 60 disposed outside the hinge 30.

The connection line 60 may be a connection line 60 having an electrical connection function and/or a mechanical connection function. In the case of the glasses according to the above-described glasses embodiment of the present application, the hinge assembly 122 is used to connect the functional element 20 to the end of the temple body 121 far from the glasses frame 11, and the control circuit or the like related to the functional element 20 may be disposed in the temple body 121, and at this time, the connecting wire 60 is required to electrically connect the functional element 20 and the control circuit or the like in the temple body 121. Specifically, the connection line 60 may be located at one side of the hinge base 31 and the hinge arm 32, and disposed in the same accommodating space as the hinge 30.

Further, the hinge base 31 includes a first end surface 312, and the hinge arm 32 has a second end surface 321 disposed opposite to the first end surface 312, and it is easy to understand that a certain gap exists between the first end surface 312 and the second end surface 321 to enable the hinge base 31 and the hinge arm 32 to relatively rotate about the rotation axis 33. In the present embodiment, during the relative rotation of the hinge arm 32 and the hinge base 31, the relative position between the first end surface 312 and the second end surface 321 is changed, so that the gap therebetween is increased or decreased.

In the present embodiment, the gap between the first end surface 312 and the second end surface 321 is always kept larger or smaller than the diameter of the connecting wire 60, so that the connecting wire 60 located outside the hinge 30 is not clamped in the gap between the first end surface 312 and the second end surface 321 during the relative rotation between the hinge base 31 and the hinge arm 32, and damage of the hinge to the connecting wire 60 is reduced. Specifically, the ratio of the gap between the first end surface 312 and the second end surface 321 to the diameter of the connecting wire 60 during the relative rotation of the hinge arm 32 and the hinge base 31 may be always maintained to be greater than 1.5 or less than 0.8, such as greater than 1.5, 1.7, 1.9, 2.0, etc., or less than 0.8, 0.6, 0.4, 0.2, etc., without being particularly limited thereto.

Referring to fig. 1, 6 to 9, fig. 6 is a view of an original state of a protection sleeve in an embodiment of a hinge assembly according to the present application, fig. 7 is a partial sectional view of the original state of the protection sleeve in an embodiment of the hinge assembly according to the present application, fig. 8 is a view of a bending state of the protection sleeve in an embodiment of the hinge assembly according to the present application, and fig. 9 is a partial sectional view of the bending state of the protection sleeve in an embodiment of the hinge assembly according to the present application. In this embodiment, the hinge assembly 122 may further include a protective sleeve 70.

Specifically, the protection sleeve 70 is sleeved on the periphery of the hinge 30 and is bent along with the hinge 30, wherein the protection sleeve 70 comprises a plurality of annular ridges 71 arranged at intervals along the length direction of the protection sleeve 70, and annular connecting parts 72 arranged between the annular ridges 71 and used for connecting two adjacent annular ridges, wherein the pipe wall thickness of the annular ridges 71 is larger than the pipe wall thickness of the annular connecting parts 72.

The length direction of the protection sleeve 70 is consistent with the length direction of the hinge 30, and the protection sleeve 70 may be specifically disposed along the length direction of the hinge base 31 and the hinge arm 32. The protective sleeve 70 may be made of a soft material, such as soft silica gel, rubber, or the like.

The annular ridge portion 71 may be further formed to protrude outward from the outer side wall of the protection sleeve 70, and the shape of the inner side wall of the protection sleeve 70 corresponding to the annular ridge portion 71 is not particularly limited herein. For example, the inner side wall may be smooth, or a recess or the like may be provided at a position corresponding to the annular ridge portion 71 on the inner side wall.

The annular connecting portion 72 is used to connect adjacent annular ridge portions 71, and is specifically connected to an edge region of the annular ridge portions 71 near the inside of the protection sleeve 70, so that the side of the outer side wall of the protection sleeve 70 may be recessed with respect to the annular ridge portions 71.

Specifically, the number of the annular ridge portion 71 and the annular connecting portion 72 may be set according to actual use, and for example, may be set according to the length of the protection sleeve 70, the width of the annular ridge portion 71 and the annular connecting portion 72 themselves in the length direction of the protection sleeve 70, and the like.

Further, the wall thicknesses of the annular ridge portion 71 and the annular connecting portion 72 refer to the thicknesses between the inner side wall and the outer side wall of the protection sleeve 70 corresponding to the annular ridge portion 71 and the annular connecting portion 72, respectively. In the present embodiment, the wall thickness of the annular ridge portion 71 is larger than the wall thickness of the annular connecting portion 72.

As will be readily appreciated, upon relative rotation between the hinge mount 31 and the hinge arm 32 of the hinge 30 about the rotation axis 33, the angle between the hinge mount 31 and the hinge arm 32 changes, thereby causing the protection sleeve 70 to bend, as shown in fig. 8 and 9. Specifically, when the protective tube 70 is bent along with the hinge 30, the annular ridge portion 71 and the annular connecting portion 72 located at the outer region of the bent shape formed by the protective tube 70 are in a stretched state, and the annular ridge portion 71 and the annular connecting portion 72 located at the inner region of the bent shape are in a pressed state.

In this embodiment, the thickness of the pipe wall of the annular ridge portion 71 is greater than that of the annular connecting portion 72, so that the annular ridge portion 71 is harder relative to the annular connecting portion 72, and thus when the protection sleeve 70 is in a bent state, the protection sleeve 70 on the outer side of the bent shape is in a stretched state, and the annular ridge portion 71 can provide a certain strength support for the protection sleeve 70; meanwhile, the protection sleeve 70 area at one side of the inside in the bending state is extruded, and the annular ridge 71 can bear a certain extrusion force, so that the protection sleeve 70 is protected, the stability of the protection sleeve 70 is improved, and the service life of the protection sleeve 70 is prolonged.

Further, it should be noted that the shape of the protective sleeve 70 corresponds to the state in which the hinge 30 is located. In one application scenario, the protective sleeve 70 may be stretched or squeezed on both sides in the length direction and about the rotational axis. In another application scenario, the hinge base 31 and the hinge arm 32 of the hinge 30 can only rotate within a range of less than or equal to 180 ° around the rotation shaft 33, that is, the protection sleeve 70 can only bend towards one side, so that one of two sides of the protection sleeve 70 along the length direction can be extruded, and the other side can be stretched, at this time, two sides of the protection sleeve 70 with different stress can be set to different structures according to different stresses of the two sides of the protection sleeve 70.

In one embodiment, the annular ridge 71 has a greater width along the length of the protective sleeve 70 toward the outside of the folded shape formed by the protective sleeve 70 when the protective sleeve 70 is in the folded state than toward the inside of the folded shape.

Wherein, increasing the width of the annular ridge portion 71 in the length direction of the protection sleeve 70 can further improve the strength of the protection sleeve. Meanwhile, in the present embodiment, the initial angle between the hinge base 31 and the hinge arm 32 is smaller than 180 °, and in this case, if the annular ridge 71 of the protection sleeve 70 is uniformly disposed, the protection sleeve 70 is pressed in the original state. In the present embodiment, the width of the annular ridge portion 71 on the side of the outer region facing the bent shape in the bent state is large, so that the length of the side protection sleeve 70 can be increased, and the strength of the protection sleeve 70 can be improved, and the degree of stretching on the stretching side can be reduced to some extent when the protection sleeve 70 is bent; meanwhile, the width of the annular ridge portion 71 in the longitudinal direction of the protection sleeve 70 toward the side of the inner region of the bent shape when the protection sleeve 70 is in the bent state is small, and the space of the pressed annular connecting portion 72 in the longitudinal direction of the protection sleeve 70 can be increased, so that the pressing on the pressing side can be relieved to some extent.

Further, in one application scenario, the width of the annular ridge portion 71 gradually becomes smaller from the side toward the outer region of the folded shape toward the side toward the inner region of the folded shape, so that the width of the side toward the outer region of the folded shape formed by the protective sleeve 70 is larger than the width of the side toward the inner region of the folded shape when the protective sleeve 70 is in the folded state.

As will be readily understood, the annular ridge portion 71 is provided around the outer periphery of the protective tube 70, with one side corresponding to the tension side and the other side corresponding to the compression side in the length direction of the protective tube 70. In the present embodiment, the width of the annular ridge portion 71 gradually decreases from the side toward the outer region of the bent shape to the side toward the inner region of the bent shape, so that the width is relatively uniform, and the stability of the protective sleeve 70 can be improved to some extent.

In one embodiment, the annular ridge 71 is provided with a groove 711 on the inner circumferential surface of the inside of the protection sleeve 70 facing the outer side of the bent shape formed by the protection sleeve 70 when the protection sleeve 70 is in the bent state.

Specifically, the grooves 711 in the present embodiment are provided in a direction perpendicular to the length direction of the protective sleeve 70, thereby enabling appropriate stretching of the corresponding annular ridge portions 71 when the protective sleeve 70 is stretched in the length direction.

As described above, in the present embodiment, when the protection sleeve 70 is in the folded state, the protection sleeve 70 facing the outer side of the folded shape formed by the protection sleeve 70 is in the stretched state, and the groove 711 is further provided on the inner circumferential surface of the protection sleeve 70 corresponding to the corresponding annular ridge 71, so that the annular ridge 71 corresponding to the groove 711 can be properly stretched to bear part of the stretching force when the protection sleeve on the side is stretched, thereby reducing the tensile force applied to the protection sleeve 70 on the side, and further protecting the protection sleeve 70.

It is to be noted that the annular ridge portion 71 on the side facing the inside region of the bent shape may not be provided with the groove 71 on the inner side wall of the corresponding protection sleeve 70 when the protection sleeve 70 is in the bent state. In one embodiment, the width of the groove 71 in the longitudinal direction of the protection sleeve 70 is gradually smaller from the side toward the outer side of the folded shape toward the side toward the inner side of the folded shape, so that no groove 711 is provided on the inner side wall of the protection sleeve 70 corresponding to the annular ridge 71 on the side toward the inner side of the folded shape.

Specifically, when the hinge assembly 122 in the present embodiment is applied to the glasses in the glasses embodiment of the present application, the protection sleeve 70 may be coupled with the temple body 121 and the function member 20 respectively provided at both sides in the length direction of the protection sleeve 70. In one application scenario, the protective sleeve 70 may also be integrally formed with other structures in the glasses, such as protective cover layers of some components, etc., so that the glasses are more closed and integrated.

It should be noted that the hinge assembly 122 of the hinge assembly embodiment of the present application may be used not only in the glasses of the glasses embodiment of the present application, but also in other devices, and the hinge assembly 122 may further include other members associated with the hinge 30 in addition to the rod-shaped member 40, the fixing member 50, the connection wire 60, the protection sleeve 70, etc. described above to achieve the corresponding functions.

Specifically, please refer to fig. 10 to 14 together, fig. 10 is a partial cross-sectional view of an embodiment of the hinge of the present application, fig. 11 is an enlarged view of a portion a in fig. 10, fig. 12 is an enlarged view of a portion B in fig. 11 when the first support surface is abutted against the third support surface and is shifted to the second support surface is abutted against the third support surface so that a connection portion between the first support surface and the second support surface is initially contacted with the third support surface, fig. 13 is a partial cross-sectional view of an embodiment of the hinge of the present application, and fig. 14 is an enlarged view of a portion C in fig. 13. It should be noted that the hinge 30 in the hinge embodiment of the present application may be used in the glasses embodiment of the present application, the hinge assembly 122 in the hinge assembly embodiment of the present application, and other devices, which are not specifically limited herein.

In this embodiment, the hinge arm 32 of the hinge 30 has a first support surface 322 and a second support surface 323 that are connected to each other.

The hinge 30 further includes a support 34 and an elastic member 35. The supporting member 34 is movably disposed on the hinge base 31 and has a third supporting surface 341, and the elastic member 35 is configured to elastically bias the supporting member 34 toward the hinge arm 32, so that the third supporting surface 341 can elastically abut against the first supporting surface 322 and the second supporting surface 323, respectively.

When the hinge arm 32 is rotated relative to the hinge base 31 by an external force, the joint 324 of the first support surface 322 and the second support surface 323 pushes the support member 34 to move reversely against the elastic bias of the elastic member 35, so that the third support surface 341 is elastically abutted against one of the first support surface 322 and the second support surface 323 to be elastically abutted against the other of the first support surface 322 and the second support surface 323.

In an application scenario, the support member 34 is connected to an end of the elastic member 35 facing the hinge arm 32, and the third support surface 341 faces the hinge arm 32, and during the rotation of the hinge arm 32 about the rotation axis 33 relative to the hinge base 31 due to the external force, the third support surface 341 can be pushed to make the support member 34 press the elastic member 35, and further, the third support surface 341 is elastically biased under the action of the elastic member 35. Of course, the support 34 may not be connected to the elastic member 35, but merely abut against one side of the support 34, so long as the support 34 can be elastically biased as described above.

The first supporting surface 322 and the second supporting surface 323 are respectively two adjacent sides of the hinge arm 32, at least part of which is parallel to the central axis of the rotating shaft 33, or are part of the two sides, when the hinge arm 32 rotates relative to the hinge seat 31, the first supporting surface 322 and the second supporting surface 323 rotate along with the hinge arm 32 around the rotating shaft 33, so that different sides of the hinge arm 32 face the hinge seat 31, and further the hinge arm 32 can have different relative positional relationships relative to the hinge seat 31.

In addition, the elastic member 35 is a member capable of providing an elastic force and capable of being compressed in an elastic force direction to provide a certain compression space. For example, the elastic member 35 may be a spring, one end of the spring abuts against the supporting member 34, and when the third supporting surface 341 of the supporting member 34 is pushed toward the elastic member 35, the elastic member 35 resists the supporting member 34 and compresses to provide a space in a direction in which the third supporting surface 341 of the supporting member 34 faces, so that when the relative position of the rotating shaft 33 is unchanged, there is still enough space for the different sides of the hinge arm 32 to rotate between the rotating shaft 33 and the third supporting surface 341.

Specifically, the relative position of the rotation shaft 33 does not change when the hinge arm 32 rotates with respect to the hinge base 31, and the contact position of the hinge arm 32 with the third supporting surface 341 of the hinge base 31 changes, and since the distances from the different positions of the hinge arm 32 to the rotation shaft 33 are different, the space between the required rotation shaft 33 to the contact point of the hinge arm 32 with the third supporting surface 341 is different when the different positions of the hinge arm 32, such as the different positions of the first supporting surface 322 and the second supporting surface 323, are in contact with the third supporting surface 341. And limited by the spring force and space, etc., the space provided by the compression of the spring 35 may be limited. Therefore, if a certain position of the hinge arm 32 is too far from the rotating shaft 33 in a section perpendicular to the central axis of the rotating shaft 33 during the rotation of the hinge arm 32 relative to the hinge base 31, the position will be blocked at another position on the third supporting surface during the rotation, and the hinge arm 32 and the hinge base 31 cannot rotate continuously, so that the hinge arm 32 and the hinge base 31 can rotate relatively only within a certain range. In one application scenario, during the relative rotation between the hinge arm 32 and the hinge base 31 about the rotation axis 33, only the region corresponding to the first support surface 322 and the second support surface 323 and the connection 324 between the first support surface 322 and the second support surface 323 can abut against the third support surface 341.

Further, in the present embodiment, the first supporting surface 322 and the second supporting surface 323 may be both planar, and the distance from the joint 324 between the rotating shaft 33 and the first supporting surface 322 is greater than the distance from the rotating shaft 33 to the second supporting surface 323, and the hinge 30 may have two relatively stable states that the third supporting surface 341 abuts against the first supporting surface 322 and the third supporting surface 341 abuts against the second supporting surface 323.

Of course, in the present embodiment, the first supporting surface 322 and the second supporting surface 323 may be curved surfaces with a certain radian, or may even include different sub supporting surfaces, as long as the positional relationship between the hinge arm 32 and the hinge base 31 can have at least two corresponding relatively stable states, which is not specifically limited herein. In addition, other more supporting surfaces may be disposed on the hinge arm 32, so that when the hinge arm 32 receives an external force to rotate relatively between the rotating shaft 33 and the hinge base 31, different supporting surfaces on the hinge arm 32 elastically abut against the third supporting surface 341 to enable the hinge arm 32 and the hinge base 31 to have different relative positions, which is not limited herein.

Specifically, taking an initial state in which the first supporting surface 322 abuts against the third supporting surface 341 of the supporting member 34 as an example, as shown in fig. 10 and 11 in particular. The elastic member 35 may have elastic compression deformation or may be in an original natural state, which is not limited herein. When the hinge 30 is subjected to an external force to cause the hinge arm 32 to rotate relative to the hinge seat 31 about the rotating shaft 33 so that the second supporting surface 323 is gradually close to the third supporting surface 341, the connection portion 324 of the first supporting surface 322 and the second supporting surface 323 contacts with the third supporting surface 341, and the distance from the connection portion 324 to the rotating shaft 33 is greater than the distance from the first supporting surface 322 to the rotating shaft 33, so that the connection portion 324 abuts against the supporting member 34 and pushes the supporting member 34 to move towards the direction of the elastic member 35, and the elastic member 35 overcomes the pushing force to generate compression. And when the hinge arm 32 is further stressed, the connection portion 324 gradually approaches the region between the rotating shaft 33 and the third supporting surface 341, and in the process, the distance between the rotating shaft 33 and the third supporting surface 341 gradually increases; as will be readily appreciated, when the connection line between the connection point 324 and the rotating shaft 33 is perpendicular to the third supporting surface 341, on a section perpendicular to the central axis of the rotating shaft 33, the distance from the rotating shaft 33 to the third supporting surface 341 is equal to the distance from the rotating shaft 33 to the connection point 324, and the rotating shaft 33 is farthest from the third supporting surface 341; at this time, if the force is continuously applied to the hinge 30, the distance from the rotating shaft 33 to the third supporting surface 341 is gradually reduced, so that the space required for compressing the elastic member 35 is reduced, and the elastic member 35 is gradually released to restore until the connecting portion 324 leaves the third supporting surface 341, so that the second supporting surface 323 is abutted against the third supporting surface 341, and the switching between the abutment of the first supporting surface 322 and the third supporting surface 341 against the second supporting surface 323 and the third supporting surface 341 is realized.

Likewise, the process (specifically, as shown in fig. 13 and 14) of switching to the abutment of the second support surface 323 with the third support surface 341 of the support 34 and the abutment of the first support surface 322 with the third support surface 341 of the support 34 in the initial state is similar to the above-described process.

It should be noted that the hinge 30 of the present embodiment can be applied to the hinge assembly 122 of the eyeglass embodiment of the present application. In one application scenario, the functional element 20 is the bone conduction speaker mechanism 21, and when the third supporting surface 341 is elastically abutted against one of the first supporting surface 322 and the second supporting surface 323 to be elastically abutted against the other of the first supporting surface 322 and the second supporting surface 323, the hinge assembly 122 drives the bone conduction speaker mechanism 21 to be capable of being switched between the first relative fixed position and the second relative fixed position relative to the temple body 121, and is capable of being attached to the back of the auricle of the user when the bone conduction speaker mechanism 21 is in the first relative fixed position.

Specifically, a first relative fixed position of the bone conduction speaker mechanism 21 with respect to the temple body 121 is shown in fig. 15, and a second relative fixed position with respect to the temple body 121 is shown in fig. 1.

Wherein the auricle is a part of the outer ear and is mainly composed of cartilage. In this embodiment, the speaker mechanism is attached to the back surface of the auricle, and bone conduction sound and vibration can be transmitted by the cartilage of the auricle. The loudspeaker mechanism is attached to the back of the auricle, so that the influence on the auditory canal in the process of sound transmission can be reduced while the sound quality is improved.

It should be noted that the distance from the rotation axis 33 to the connection portion 324 is greater than the perpendicular distance from the first support surface 322 and the second support surface 323, so that a certain jump occurs in the state of the hinge 30 during the switching of the third support surface 341 from the elastic abutment with one of the first support surface 322 and the second support surface 323 to the elastic abutment with the other of the first support surface 322 and the second support surface 323.

Taking the elastic contact between the first supporting surface 322 and the third supporting surface 341 as an example, the elastic contact between the second supporting surface 323 and the third supporting surface 341 is switched to the maximum distance h between the rotating shaft 33 and the connecting portion 324 ₁ Shortest distance h from rotating shaft 33 to first supporting surface 322 ₂ When the ratio is different, the jump degree generated in the switching process is different.

In one embodiment, in a section perpendicular to the central axis of the shaft 33, the maximum distance h of the shaft 33 from the connection 324 ₁ Shortest distance h from rotating shaft 33 to first supporting surface 322 ₂ The ratio between them is between 1.1 and 1.5.

In particular, the maximum distance h of the rotation axis 33 to the connection 324 can be achieved by arranging the rotation axis 33 away from the second support surface 323 and close to a side of the hinge arm 32 opposite to the second support surface 323 ₁ Greater than the shortest distance h from the rotating shaft 33 to the first supporting surface 322 ₂ Thereby satisfying the above ratio.

It should be noted that h ₁ And h ₂ When the proportion is too large, the jump is obvious, but a larger force may need to be applied to switch the elastic abutting of the first supporting surface 322 and the third supporting surface 341 to the elastic abutting of the second supporting surface 323 and the third supporting surface 341, so that inconvenience is brought to a certain extent for use; and h is ₁ And h ₂ If the ratio is too small, the state is easily switched, but the degree of jump may be small, for example, there is no noticeable touch when the user pulls the hinge 30, which is inconvenient. Will h in this embodiment ₁ And h ₂ The ratio of (2) is set between 1.1 and 1.5, so that when the third supporting surface 341 is elastically abutted against the first supporting surface 322 to be elastically abutted against the second supporting surface 323, the hinge 30 has obvious jump, so that in the use process, a user pulls the hinge 30 to have obvious handfeel, and meanwhile, the jump state is not too abrupt, so that the user is difficult to switch the state of the hinge 30.

In one application scenario, h ₁ And h ₂ The ratio of (2) may also be between 1.2 and 1.4, in particular h ₁ And h ₂ The ratio of (c) may be 1.1, 1.2, 1.3, 1.4, 1.5, etc., and is not particularly limited herein.

In addition, the arrangement of the positions of the first support surface 322 and the second support surface 323 on the hinge arm 32 affects the angle of the included angle between the hinge arm 32 and the hinge seat 31 when the third support surface 341 is abutted against one of the first support surface 322 and the second support surface 323, so that the positions of the first support surface 322 and the second support surface 323 on the hinge arm 32 can be set differently according to specific use requirements. Wherein, the included angle between the hinge arm 32 and the hinge base 31 is ω as shown in fig. 10 and 13 ₁ An angle ω between the hinge arm 32 and the hinge base 31 when the third supporting surface 341 abuts the first supporting surface 322 ₂ The angle between the hinge arm 32 and the hinge base 31 when the third supporting surface 341 abuts against the second supporting surface 323. In an embodiment, the hinge arm 32 and the hinge seat 31 have a certain length, the hinge arm 32 is disposed at one side of the end of the hinge seat 31 in the length direction, the first supporting surface 322 is disposed at the end of the hinge arm 32 near the hinge seat 31 in the length direction, and the second supporting surface 323 is disposed at one end of the hinge arm 32 in the width direction and is parallel to the central axis of the rotating shaft 33. At this time, the angle between the hinge arm 32 and the hinge base 31 is the largest when the third supporting surface 341 is elastically abutted against the first supporting surface 322, and the angle between the hinge arm 32 and the hinge base 31 is the smallest when the third supporting surface 341 is elastically abutted against the second supporting surface 323, so that the angle between the hinge base 31 and the hinge arm 12 is made from ω when the third supporting surface 341 is switched from being elastically abutted against the first supporting surface 322 to being elastically abutted against the second supporting surface 323 ₁ Becomes omega ₂ But becomes smaller.

It should be further noted that, if the direction of the force applied to the hinge arm 32 when the third supporting surface 341 is switched from the elastic abutment with the first supporting surface 322 to the elastic abutment with the second supporting surface 323 is consistent with the direction of the gravity of the hinge arm 32 itself, the angle between the hinge base 31 and the hinge arm 12 becomes smaller when the switching in this stateIn the above h ₁ And h ₂ The ratio between them may also be set such that the hinge arm 32 does not or hardly spontaneously reduce its angle with the hinge base 31 due to its own weight when the third supporting surface 341 elastically abuts against the first supporting surface 322.

In one embodiment of the hinge of the present application, referring to fig. 12, in a section perpendicular to the central axis of the rotating shaft 33, an angle ω between the first supporting surface 322 and the second supporting surface 323 is formed ₃ Is an obtuse angle.

When the hinge 30 is switched from the state in which the first support surface 322 is elastically abutted against the third support surface 341 to the state in which the second support surface 323 is elastically abutted against the third support surface 341, the angle ω between the first support surface 322 and the second support surface 323 is increased ₃ The smaller the angle between the hinge seat 31 and the hinge arm 32 to be rotated is, that is, when the hinge seat 31 is fixed, the user needs to pull the hinge arm 32 by a larger angle to switch the state of the hinge 30, so that the user is hard to use and inconvenient to use.

Since the hinge arm 32 has a certain length, the first supporting surface 322 is disposed at one end of the hinge arm 32 in the length direction, and the second supporting surface 323 is disposed adjacent to the first supporting surface 322 in the width direction of the hinge arm 32. Normally, the first support surface 322 is perpendicular to the second support surface 323, and at this time, when the hinge 30 is switched between the two states, the hinge arm 32 and the hinge base 31 need to be moved by 90 ° relative to each other.

In the present embodiment, the angle ω between the first support surface 322 and the second support surface 323 is equal to the angle ω ₃ Is obtuse, so that the angle required for the relative movement of the hinge arm 32 and the hinge base 31 is less than 90 ° when the hinge 30 is switched between the two states, thereby providing a degree of convenience to the user.

Specifically, when the hinge 30 in the present embodiment is used in the eyeglass embodiment of the present application, the hinge 30 is used to connect the temple body 121 and the bone conduction speaker apparatus 21, and when the hinge 30 is in the second state in which the second supporting surface 323 is elastically abutted against the third supporting surface 341, the bone conduction speaker apparatus 21 is in the first relatively fixed position to be attached to the back of the auricle of the user, so that when the user needs to use the function of the bone conduction speaker apparatus 21 of the eyeglass, only the bone conduction speaker apparatus 21 needs to be rotated by an angle smaller than 90 ° to be attached to the back of the auricle of the user; in addition, when the hinge 30 is in the first state in which the first supporting surface 322 is elastically abutted against the third supporting surface 341, the hinge arm 32 and the connected bone conduction speaker mechanism 21 form a certain angle, so that when the user wears the glasses, the hinge arm 32 and the connected bone conduction speaker mechanism 21 can be positioned behind the ears of the user and arranged towards the directions of the ears of the user, thereby playing a certain role in blocking and fixing the glasses, and being not easy to fall from the head of the user.

It should be noted that the angle ω between the first support surface 322 and the second support surface 323 ₃ The specific angle of (2) can be set according to actual needs. When the angle of the included angle is too large, the included angle between the hinge arm 32 and the functional piece 20 connected to the end part of the hinge arm 32 far away from the hinge seat 31 and the hinge seat 31 is smaller, so that when a user wears the multifunctional device, the hinge arm 32 and the functional piece 20 are too close to the ears of the user to press the ears of the user, and the comfort level of the user is reduced; if the included angle is too small, on the one hand, when the user pulls the bone conduction speaker mechanism 21 to switch between the first relative position and the second relative position, the angle required to be pulled is too large, which is inconvenient for the user to use, and on the other hand, the included angle formed between the glasses leg main body 121 and the hinge 30 and the bone conduction speaker mechanism 21 is small, which is difficult to block and fix the glasses, so that the glasses are easy to drop from the front side of the head of the user when the user wears the glasses. In particular, a specific angle of the included angle between the first support surface 322 and the second support surface 323 may be set according to the head shape of the user.

Specifically, in one application scenario, in a cross section perpendicular to the central axis of the rotating shaft 33, an angle ω between the first support surface 322 and the second support surface 323 ₃ The angle of (2) is between 100 DEG and 120 DEG, and may be specifically 100 DEG, 110 DEG, 120 DEG, etc. The setting of the angle can enable the user to wear the glasses andwhen the bone conduction speaker mechanism 21 is at the first relative fixed position, the bone conduction speaker mechanism 21 is not too close to the user's ear to cause discomfort to the user's ear, and the hinge is not required to be rotated by an excessive angle when the two relative positions of the bone conduction speaker mechanism 21 are switched, so that the use of the bone conduction speaker mechanism is convenient for the user.

Wherein, during the process that the third supporting surface 341 is switched from being elastically abutted against one of the first supporting surface 322 and the second supporting surface 323 to being elastically abutted against the other of the first supporting surface 322 and the second supporting surface 323, the connection portion 324 between the first supporting surface 322 and the second supporting surface 323 abuts against the third supporting surface 341, and pushes the supporting member 34 to reversely move against the elastic bias of the elastic member 35. Taking the elastic abutment of the third supporting surface 341 and the first supporting surface 322 before switching as an example, during initial switching, the first supporting surface 322 gradually moves away from the third supporting surface 341, and at the same time, the connecting portion 324 gradually abuts against the third supporting surface 341, and during switching, one side of the third supporting surface 341 slides to the other side of the third supporting surface 341, and finally further transitions to the elastic abutment of the second supporting surface 323 and the third supporting surface 341. During the state switching process, the connection portion 324 is always abutted against the third supporting surface 341 to interact, and the shape of the connection portion 324 may have a certain influence on the state switching process. For example, if the first support surface 322 and the second support surface 323 are connected by a line, the connection portion 324 has a relatively sharp angle, so that when the user pulls the hinge seat 31 and/or the hinge arm 32 to switch the state of the hinge 30, on one hand, the connection portion 324 is in contact with the third support surface 341 and the connection portion 324 is in contact with the first support surface 322 and the second support surface 323 to switch, the buffering is relatively small, the switching is abrupt, and the hand feeling of pulling the hinge 30 is poor; on the other hand, the connection 324 is relatively sharp, which causes a certain wear to the third supporting surface 341 during repeated switching.

In one embodiment of the present application, the connection portion 324 is disposed in an arc shape in a section perpendicular to the central axis of the rotating shaft 33. Therefore, the connection between the first supporting surface 322 and the second supporting surface 323 is a cambered surface connection, and the connection portion 324 abutting against the third supporting surface 341 is smoother in the process of switching the state of the hinge 30, so that the user has better hand feeling when pulling the hinge 30, and the damage to the third supporting surface 341 in the repeated switching process can be reduced.

Specifically, in one embodiment, the connection portion 324 is configured as an arc, and the curvature of the arc is different, so that the effect of the arc is different, and the specific curvature value needs to be set in combination with the actual use situation. In the present embodiment, the curvature of the circular arc is between 5 and 30, and may be specifically 5, 10, 15, 20, 25, 30, etc., which is not limited herein.

It should be noted that, when the hinge 30 of the present embodiment is applied to the glasses of the above glasses embodiment, the curvature of the connecting portion 324 disposed in the circular arc can enable the user to have a better hand feeling when pulling the hinge 30 to switch the bone conduction speaker between the first relative fixed position and the second relative fixed position.

In an embodiment, the third supporting surface 341 is arranged such that an external force required when the third supporting surface 341 is switched from being in elastic abutment with the first supporting surface 322 to being in elastic abutment with the second supporting surface 323 is different from an external force required when the third supporting surface 341 is switched from being in elastic abutment with the second supporting surface 323 to being in elastic abutment with the first supporting surface 322.

It should be noted that, in a specific use scenario, the functions of the hinges 30 corresponding to different states of the hinges 30, or the structures connected to the hinges 30 are different, or due to the problem of the positions of the hinges 30, when one state is switched to another state, the force is inconvenient for the user to apply, and when the user switches the state of the hinges 30, the force needs to be differentiated in terms of pulling the hinge 30, so as to facilitate the user to apply the force, or provide visual feelings for the user to differentiate the two hinge states.

Specifically, when the hinge 30 of the present embodiment is applied to the glasses, the switching of the state of the hinge 30 will drive the bone conduction speaker apparatus 21 to switch between the first and second relatively fixed positions with respect to the glasses leg main body 121. Correspondingly, the two relatively fixed positions respectively correspond to the two cases that the user uses the bone conduction speaker mechanism 21 and the user does not use the bone conduction speaker mechanism 21, and the difficulty level of force application is different when the user applies force on the back side of the head to switch the two states when wearing the glasses, so that the switching of different states is correspondingly designed to be required to apply different external forces, and the user can use the glasses.

Specifically, in one embodiment, when the third supporting surface 341 is switched from the elastic abutment with the first supporting surface 322 to the elastic abutment with the second supporting surface 323, this corresponds to pulling the bone conduction speaker mechanism 21 from the second relatively fixed position to the first relatively fixed position so as to be fitted to the back of the auricle of the user.

Further, in the present embodiment, the third supporting surface 341 is provided such that an external force required when the third supporting surface 341 is switched from being in elastic abutment with the first supporting surface 322 to being in elastic abutment with the second supporting surface 323 is smaller than an external force required when the third supporting surface 341 is switched from being in elastic abutment with the second supporting surface 323 to being in elastic abutment with the first supporting surface 322.

It should be noted that, when applied to the above-described glasses, when the bone conduction speaker mechanism 21 is used, the third supporting surface 341 needs to be switched from being elastically abutted against the first supporting surface 322 to being elastically abutted against the second supporting surface 323, whereas when the bone conduction speaker mechanism 21 is not used, the third supporting surface 341 needs to be switched from being elastically abutted against the second supporting surface 323 to being elastically abutted against the third supporting surface 341, and according to the present embodiment, the force required to be applied when the bone conduction speaker mechanism 21 is used by the user is smaller than the force required to be applied when the bone conduction speaker mechanism 21 is not used, so that the function of the bone conduction speaker mechanism 21 of the glasses can be facilitated to some extent by the user.

Specifically, referring to fig. 12 and 14 together, in one application scenario, when the third supporting surface 341 is elastically abutted against the first supporting surface 322 to the second supporting surface 323, the connection portion 324 is initially contacted to the first position 3411 of the third supporting surface 341, and when the third supporting surface 341 is elastically abutted against the second supporting surface 323 to the first supporting surface 322, the connection portion 324 is initially contacted to the second position 3412 of the third supporting surface 341, wherein on a section perpendicular to the central axis of the rotating shaft 33,distance d between first position 3411 and contact point between elastic member 35 and support member 34 in elastic biasing direction of elastic member 35 ₁ Less than the distance d between the second location 3412 and the contact point in the direction of the spring bias ₂ 。

It should be noted that, when the third supporting surface 341 elastically abuts against the first supporting surface 322, the connection portion 324 is located near one end of the third supporting surface 341, and when the third supporting surface 341 elastically abuts against the second supporting surface 323, the connection portion 324 is located near the other end of the third supporting surface 341. Therefore, the first position 3411 and the second position 3412 are respectively located near two ends of the third supporting surface 341. That is, in the present embodiment, the positions of the third supporting surface 341 of the supporting member 34 near both ends are different from the distance of the contact point of the elastic member 35 and the supporting member 34 in the elastic biasing direction of the elastic member 35, and the distance corresponding to the second position 3412 is smaller than the distance corresponding to the first position 3411. At this time, when the third supporting surface 341 is switched from being elastically abutted against the first supporting surface 322 to being elastically abutted against the second supporting surface 323, the connection portion 324 is not immediately abutted against the third supporting surface 341 initially and receives the reaction force of the elastic member 35, but gradually abutted against the third supporting surface 341 and receives the reaction force of the elastic member 35 during the switching; when the third supporting surface 341 is switched from being elastically abutted against the first supporting surface 322 to being elastically abutted against the second supporting surface 323, the joint 324 initially abuts against the third supporting surface 341 to receive the reaction force of the elastic member 35, or at least the reaction force of the elastic member 35 is received earlier than when the third supporting surface 341 is switched from being elastically abutted against the second supporting surface 323 to being elastically abutted against the first supporting surface 322. Therefore, in this case, the force required for the hinge 30 to switch from the elastic abutment with the first support surface 322 to the elastic abutment with the second support surface 323 is small, so that the force required to pull the bone conduction speaker mechanism 21 when the user uses the bone conduction speaker mechanism 21 is small, thereby facilitating the use by the user.

Further, the third supporting surface 341 includes a first sub supporting surface 3413 and a second sub supporting surface 3414, where the first position 3411 is disposed on the first sub supporting surface 3413 and the second position 3412 is disposed on the second sub supporting surface 3414. That is, the first sub-supporting surface 3413 and the second sub-supporting surface 3414 are provided near both ends of the third supporting surface 341, respectively.

The second sub-supporting surface 3414 may be a plane, and in particular, when the first supporting surface 322 or the second supporting surface 323 elastically abuts against the third supporting surface 341, the second sub-supporting surface 3414 may be parallel to the first supporting surface 322 or the second supporting surface 323. The first sub-supporting surface 3413 may be a plane surface or an arc surface, which is not limited herein.

Further, the first sub-supporting surface 3413 and the second sub-supporting surface 3414 are not located on the same plane, and the first sub-supporting surface 3413 is inclined with respect to the second sub-supporting surface 3414, and an included angle between the two may be not greater than 10 °, for example, may be not greater than 2 °, 4 °, 6 °, 8 °, 10 °, and the like. Specifically, the first sub-supporting surface 3413 is disposed away from the hinge arm 32 such that, in a cross section perpendicular to the central axis of the rotation shaft 33, a distance between the first position 3411 and a contact point of the elastic member 35 and the supporting member 34 in the elastic biasing direction of the elastic member 35 is smaller than a distance between the second position 3412 and the contact point in the elastic biasing direction. When the first sub-supporting surface 3413 is a cambered surface and the second sub-supporting surface 3414 is a plane, an included angle between the first sub-supporting surface 3413 and the second sub-supporting surface 3414 is an included angle between a plane tangent to the first sub-supporting surface 3413 at an intersection of the first sub-supporting surface 3413 and the second sub-supporting surface 3414.

With further reference to fig. 16, fig. 16 is an exploded view of one embodiment of a hinge of the present application. In this embodiment, the hinge seat 31 includes a seat body 313, a first lug 314 and a second lug 315 protruding from the seat body 313 and disposed at intervals, the hinge arm 32 includes an arm body 325 and a third lug 326 protruding from the arm body 325, the third lug 326 is inserted into a space region between the first lug 314 and the second lug 315 and is rotatably connected with the first lug 314 and the second lug 315 through a rotation shaft 33, the first supporting surface 322 and the second supporting surface 323 are disposed on the third lug 326, the supporting member 34 is at least partially disposed in the space region and located at a side of the third lug 326 facing the seat body 313, the seat body 313 is provided with a receiving cavity 3121 communicating with the space region, the elastic member 35 is disposed in the receiving cavity 3121, and elastically biases the supporting member 34 toward the third lug 326.

Specifically, the corresponding positions of the first lug 314, the second lug 315 and the third lug 326 may be respectively provided with a first through hole, a second through hole and a third through hole which are located in the same axial direction, and the inner diameters of the three through holes may be not smaller than the outer diameter of the rotating shaft 33, so that when the rotating shaft 33 is inserted into the corresponding through holes, the hinge base 31 where the first lug 314 and the second lug 315 are located and the hinge arm 32 where the third lug 326 is located can be rotationally connected together.

The first supporting surface 322 and the second supporting surface 323 are disposed on the third lug 326 and parallel to the central axis of the rotating shaft 33, so that when the hinge arm 32 rotates around the rotating shaft 33 relative to the hinge base 31, the first supporting surface 322 and the second supporting surface 323 may enter a space region between the first lug 314 and the second lug 315.

Further, the supporting member 34 is located between the first lug 314 and the second lug 315 of the seat body 313, and the third supporting surface 341 of the supporting member 34 is disposed towards the third lug 326. In one application scenario, the elastic member 35 is disposed entirely within the receiving cavity 3121 and contacts the support member 34 on a side facing the spaced area between the first ledge 314 and the second ledge 315. When the elastic member 35 is in the natural state, the region of the support member 34 adjacent to the elastic member 35 is at least partially located in the accommodating cavity 3121. It should be noted that the portion of the support 34 located in the accommodating chamber 3121 is shaped to match the accommodating chamber 3121, so that the portion of the support 34 located in the accommodating chamber 3121 can stably slide within the accommodating chamber 3121 when the support 34 is elastically biased by the elastic member 35.

In one application scenario, on a cross section perpendicular to the length direction of the hinge seat 31, the cross-sectional area of the accommodating cavity 3121 is smaller than the cross-sectional area of the spacing region between the first lug 314 and the second lug 315, and the shape of the region of the support 34 located outside the accommodating cavity 3121 matches the spacing region, so that the support 34 does not entirely enter the accommodating cavity 3121 when moving toward the elastic member 35 side.

Of course, in other embodiments, the cross-sectional shape of the accommodating cavity 3121 may be the same as the interval region between the first lug 314 and the second lug 315 in a cross-section perpendicular to the length direction of the hinge base 31, and the supporting member 34 may be completely accommodated in the accommodating cavity 3121 at this time, so that the supporting member 34 slides in the entire accommodating cavity 3121 when receiving the pushing action.

Further, when the hinge 30 in the above embodiment is applied to the hinge assembly 122 in the hinge assembly embodiment of the present application, the first end face 312 of the hinge base 31 is the end faces of the first lug 314 and the second lug 315 facing the hinge arm 32, and the third lug 326 disposed toward the protrusion from the arm body 325 is located in the interval region between the first lug 314 and the second lug 315, so that the first end faces 312 of the first lug 314 and the second lug 315 are disposed toward the arm body 325. The arm body 325 further protrudes from the third lug 326 on a section in the central axis direction of the rotation shaft 33 to form the second end faces 321 of the first lug 314 and the second lug 315 toward the hinge base 31.

In the present embodiment, in the process of relatively rotating the hinge arm 32 and the hinge base 31, the gap between the first end surface 312 of the first lug 314 and the second lug 315 and the second end surface 321 of the arm body 325 is always larger or smaller than the diameter of the connecting wire 60, so that the connecting wire 60 is not clamped between the first lug 314 and the second lug 315 and the arm body 325 in the process of relatively rotating the hinge base 31 and the hinge arm 32, and damage of the hinge 30 to the connecting wire 60 is reduced.

In one application scenario, the gap between the second end surfaces 321 of the first and second lugs 314 and 315 and the first end surface 312 of the arm body 325 remains substantially larger or smaller than the diameter of the connection wire 60 throughout the relative rotation of the hinge arm 32 and the hinge mount 31, thereby further reducing damage to the connection wire 60 by the hinge 30.

It should be noted that, in the present embodiment, the gap between the first end face 312 and the second end face 321 may be a uniform gap with the same size, so as to satisfy the condition that the diameter of the connecting wire 60 is larger or smaller than the above; or in another embodiment, it may be that only the gap at the position where the two end faces are close to the connecting wire 60 satisfies the diameter larger or smaller than the connecting wire 60, while the gap at the other position of the two end faces may not satisfy the above condition.

Specifically, in one application scenario, on a section perpendicular to the central axis of the rotation shaft 33, at least one of the end face of the first lug 314 and the second lug 315 facing the hinge arm 32 and the end face of the arm body 325 facing the hinge base 31 may be provided with a chamfer such that the position of the gap between the hinge arm 32 and the hinge base 31 near the connecting wire 60 during the relative rotation thereof is always maintained to be larger than the diameter of the connecting wire 60.

The chamfer setting can be either a chamfer or a direct chamfer.

In this application scenario, only the end face of the first lug 314 and the second lug 315, which are close to the connecting line 60, facing the hinge arm 32 and at least one of the end faces of the arm body 325, facing the hinge seat 31 need be chamfered, so that the connecting line 60 is not clamped in the gap between the two end faces in the process of relative rotation between the hinge arm 32 and the hinge seat 31.

The hinge in the hinge embodiments described above may be applied to the hinge assembly embodiments of the present application, but is not limited thereto, and may be applied to other hinge assemblies in other embodiments, or two members that need to be rotatably connected may be directly connected.

Further, in an embodiment of the glasses of the present application, the functional element 20 is a bone conduction speaker mechanism 21. The center point O of the fitting surface 211 of the bone conduction speaker mechanism 21 to the ear, the center plane α of the rotation shaft 33 of the hinge 30, the symmetry plane β of the hinge 30, and the like are in the same plane or within a predetermined error range of the opposite plane.

The perpendicular plane α of the rotating shaft 33 refers to a plane perpendicular to the axial direction of the rotating shaft 33 of the hinge 30 and symmetrically dividing the rotating shaft 33, refer to fig. 17.

The symmetry plane β of the hinge 30 refers to a plane that symmetrically divides the hinge 30, i.e. the hinge 30 is symmetrically distributed on two sides of the symmetry plane β of the hinge 30, refer to fig. 18.

The predetermined error range may be obtained by combining experience with statistical data of the material, specification, shape of the ear, and the like of the hinge 30.

It should be noted that, when the center point of the middle vertical plane α of the rotating shaft 33 of the hinge 30, the symmetry plane β of the hinge 30, and the fitting surface 211 of the bone conduction speaker mechanism 21 to which the ear is fitted are in the same plane, the bone conduction speaker mechanism 21 connected to the hinge 30 can be directly fitted to the back of the auricle of the user, when the hinge 30 is deformed under stress, the deformation directions and the movement directions of the bone conduction speaker mechanism 21 are consistent and all lie in the plane, so that when the planes and points are not in the same plane, and the hinge 30 is elastically deformed under stress, the bone conduction speaker mechanism 21 cannot be fitted to the back of the auricle of the user due to torsion of the hinge 30 and the bone conduction speaker mechanism 21, thereby reducing the sound/vibration transmission efficiency and further reducing the sound quality of the bone conduction speaker device. Of course, the center point of the middle vertical surface α of the rotating shaft 33, the symmetry plane β of the hinge 30, and the fitting surface 211 of the bone conduction speaker unit 2120, which fits the ear, may be within a predetermined error range of the relative plane, so that the user will not be excessively affected during the actual use, but it should be noted that, at this time, the fitting effect of the fitting surface 211 of the bone conduction speaker unit 21 and the back of the auricle of the user may be affected to some extent.

Further, when the bone conduction speaker apparatus 21 is in the first relative fixed position with respect to the temple bodies 121, the angle between the horizontal reference plane γ defined by the tops of the two temple bodies 121 and the symmetry plane θ of the fixing member 50 in the longitudinal direction of the temple bodies 121 is 65 ° to 85 °.

Wherein the horizontal reference plane γ defined by the tops of the two temple bodies 121 refers to a plane tangential to the tops of the two temple bodies 121 at the same time, and in one application scenario, the plane is further perpendicular to the symmetry plane of the glasses frame 11, as shown in fig. 19 in particular; the symmetry plane θ of the fixing member 50 in the longitudinal direction of the temple body 121 means a symmetry plane of the fixing member 50 in the longitudinal direction of the temple body 121, as shown in fig. 20.

In the present embodiment, when the bone conduction speaker mechanism 21 is at the first relative fixed position with respect to the temple body 121, the fixing member 50 is aligned with the hinge 30, the symmetry plane θ of the fixing member 50 in the longitudinal direction of the temple body 121 is in the same plane as the symmetry plane of the hinge 30 in the longitudinal direction of the hinge 30, and the end of the hinge 30 away from the temple body 121 is connected to the bone conduction speaker mechanism 21.

In addition, when the bone conduction speaker unit 21 is at the first relative fixed position with respect to the temple body 121, the angle between the horizontal reference plane γ defined by the top portions of the two temple bodies 121 and the symmetry plane θ of the fixing member 50 in the longitudinal direction of the temple body 121 may be 70 ° to 82 °, so that the bone conduction speaker unit 21 further fits in the auricle back area opposite to the auricle foot position.

Specifically, when the bone conduction speaker apparatus 21 is in the first relative fixed position with respect to the temple body 121, the angle between the horizontal reference plane γ defined by the top portions of the two temple bodies 121 and the symmetry plane θ of the fixing member 50 in the longitudinal direction of the temple body 121 may be any angle within the above-mentioned range, such as 70 °, 75 °, 80 °, 82 °, and the like, and is not particularly limited herein.

Further, when the bone conduction speaker mechanism 21 is in the first relatively fixed position with respect to the temple body 121, the angle between the symmetry plane λ of the eyeglass frame 11 and the symmetry plane β of the hinge 30 is 5 ° to 30 °.

The symmetry plane λ of the eyeglass frame 11 is a symmetry plane that symmetrically divides the eyeglass frame 11, as shown in fig. 21. The symmetry plane β of the hinge 30 is the same as that shown in fig. 18 described above, and will not be described again here.

The angle between the symmetry plane λ of the glasses frame 11 and the symmetry plane β of the hinge 30 is related to the head shape of the user, for example, the angle corresponding to the european and asian population is different. When worn by a user, the bottom surface of the temple body 121 is supported by the user's ears, and the bone conduction speaker mechanism 21 is fixed in place by the side surface of the temple body 121 abutting against the side surface of the user's head. Thus, if the angle is large, the front portion of the temple body 121 abuts the head, while the rear portion is away from the head; if the angle is large, the front portion of the temple body 121 is away from the head and the rear portion abuts against the head, and in both cases, the temple body 121 cannot be in good contact with the head, so that the bonding surface 211 of the bone conduction speaker mechanism 21 is easily separated from the back of the auricle, thereby reducing the sound quality of the bone conduction speaker mechanism 21 and bringing inconvenience to the user.

When the bone conduction speaker unit 21 is at the first relative fixed position with respect to the temple body 121, the angle between the symmetry plane λ of the eyeglass frame 11 and the symmetry plane β of the hinge 30 may be 10 ° to 25 °, specifically, may be 10 °, 15 °, 20 °, 25 °, and the like, which is not limited herein.

Further, referring to fig. 22, a distance h between center points of the rotating shafts 33 corresponding to the two temples 12 ₃ May be 90 to 150mm. The distance h ₃ Corresponding to the left-right width of the user's head.

As will be readily appreciated, the two temples 12 are placed on the upper part of the user's ears and clamped on the two sides of the head, if the distance h between the center points of the corresponding axes of rotation 33 of the two temples 12 ₃ If the clamping force of the glasses leg 12 towards the head of the user is relatively small, the situation of 'clamping loose' can occur, so that the glasses leg is easy to loosen from the head of the user, and the bone conduction loudspeaker mechanism 21 is deviated from the position corresponding to the back of the auricle; if the angle of the inward folding is small, the temple 12 will grip the head of the user too much, which is likely to cause discomfort to the user.

Wherein, the distance h between the center points of the corresponding rotating shafts 33 of the two glasses legs 12 ₃ The thickness may be 100 to 130mm, specifically 100mm, 110mm, 120mm, 130mm, etc. It should be noted that the distance h can be selected by different head types of different users ₃ A more suitable range of headphones. Distance h of e.g. male version ₃ The range of female money can be 115-130 mm, and the range of female money can be 100-115 mm, and the female money can be set to be the middle value of the two ranges, so that the female money is suitable for two crowds at the same time.

Optionally, with continued reference to fig. 22, the vertical distance h of the line connecting the center of symmetry of the eyeglass frame 11 to the center of the two rotational shafts 33 ₄ 105-170 mm.

It should be noted that the center of symmetry of the eyeglass frame 11 is the midpoint of the bridge of the nose located in the middle of the eyeglass frame 11, and the vertical distance corresponds to the front-to-back length of the user's head.

It will be readily appreciated that if the vertical distance h ₄ If the size is large, the eyeglass frame 11 may be far from the eyes of the user when the attaching surface 211 of the bone conduction speaker mechanism 21 is attached to the back of the auricle, and the attaching surface 211 of the bone conduction speaker mechanism 21 cannot be attached to the back of the auricle properly because it is far from the back of the auricle when the earphone eyeglass frame 11 is worn properly; if the distance is small, when the eyeglass function and the earphone function are used simultaneously, the eyeglass frame 11 and the bone conduction speaker mechanism 21 simultaneously grip the head in front of and behind the head of the user, which causes discomfort to the user, or when the distance is too small, it is difficult to use both functions simultaneously.

Wherein the vertical distance h of the line connecting the symmetry center of the spectacle frame 11 to the center of the two rotary shafts 33 ₄ The diameter may be 130 to 150mm, and may be 130mm, 140mm, 150mm, or the like. It should be noted that different people can be used to correspond to different distance ranges, for example, distance h of male pattern ₄ The range of the female pattern can be 140-160 mm, and the range of the female pattern can be 105-135 mm, and the female pattern can be set to be the middle value of the two ranges, so that the female pattern is suitable for two groups of people at the same time.

Alternatively, referring to fig. 22 and 23 together, the distance h between the center point of each rotating shaft 33 and the center point O of the contact surface 211 of the corresponding bone conduction speaker mechanism 21 ₅ Perpendicular distance h from the line connecting the center of symmetry of the frame 11 to the center of the two axes of rotation 33 ₄ Ratio h of (2) ₅ /h ₄ 0.1 to 1.5.

Wherein the distance h between the center point of each rotating shaft 33 and the center point O of the attaching surface 211 of the corresponding bone conduction speaker mechanism 21 ₅ Corresponding to the distance from the center point of the rotating shaft 33 to the joint between the joint surface 211 and the back of the auricle of the user; and the vertical distance h of the line connecting the center of symmetry of the frame 11 to the center of the two axes 33 ₄ Corresponding to the vertical distance from the front of the user's head to behind the ear. Vertical distance from front of user's head to behind earFor the time being, if the distance from the center point of the rotating shaft 33 to the joint between the joint surface 211 and the back of the auricle of the user is large, that is, if the above ratio is large, it is indicated that the distance between the center point of the rotating shaft 33 and the center point O of the joint surface 211 of the corresponding bone conduction speaker mechanism 21 is large, the bone conduction speaker mechanism 21 is easily attached to the lower part of the back of the auricle; when the above ratio is small, it is explained that the distance between the center point of the rotation shaft 33 and the center point O of the contact surface 211 of the corresponding bone conduction speaker mechanism 21 is small, the bone conduction speaker mechanism 21 is easily attached to the upper part of the back of the auricle, and thus the transmission efficiency of the bone conduction speaker mechanism 21 to the sound/vibration is affected, and the sound quality is further affected.

Wherein h is ₅ /h ₄ The ratio may be 0.125-0.35, specifically, for example, 0.125, 0.15, 0.20, 0.25, 0.30, 0.35, etc., and different ratios may be designed according to different requirements of users, which is not limited herein.

Furthermore, the bone conduction sounding devices with different specifications can be set according to the different parameters, so that a user can select according to own head types to meet the use requirements of the user.

Referring to fig. 24 to 26, fig. 24 is a schematic structural view of an embodiment of the bone conduction headset of the present application, fig. 25 is an exploded structural view of an embodiment of the bone conduction headset of the present application, and fig. 26 is a cross-sectional view taken along a symmetry plane of the bone conduction headset of fig. 24. In this embodiment, the bone conduction earphone may be a separate bone conduction earphone that can be directly used, or may be a bone conduction earphone that is plugged into an electronic device for use, and in one application scenario, the bone conduction earphone in this embodiment is one of the bone conduction speaker mechanisms 21 in the above-mentioned glasses embodiment.

Among them, bone conduction is a sound conduction mode, i.e., converting sound into mechanical vibration of different frequencies, and transmitting sound waves through skull, bone labyrinth, inner ear lymph fluid transmission, screw, auditory nerve, auditory center, etc. of a person. In this embodiment, a bone conduction headset includes: earphone housing 212, transducer 213, vibration plate 214, and vibration transfer layer 215.

The earphone housing 212 defines an earphone receiving chamber 2122 having an opening 2121 for receiving the associated functional structure of the bone conduction earphone. For example, the transducer 213 may be received in the earphone receiving cavity 2122.

Specifically, the transducer 213 is configured to generate vibrations according to the audio signal. The audio signal may be an audio signal directly stored in the transducer 213, or may be an audio signal input to the transducer 213 through a signal line or the like from a storage device or a communication circuit or the like, and is not limited herein.

Further, the vibration transmitting plate 214 is connected to the transducer 213 and exposed through the opening 2121 of the receiving cavity 2122 to transmit vibration. Specifically, the transducer 213 is capable of converting an audio signal into a corresponding vibration signal, and further transmitting the vibration signal through the vibration plate 214, so as to transmit the vibration signal from the inside of the accommodating cavity 2122 of the earphone housing 212 to the outside of the earphone housing 212, so as to further transmit the vibration signal to a user directly or indirectly contacting the vibration plate 214.

Further, the vibration transmission layer 215 is coated on the outer surface of the vibration transmission plate 214, so that the vibration signal generated by the transducer 213 can be transmitted to the vibration transmission plate 214 transmission layer through the vibration transmission plate 214, and further, the vibration signal can be transmitted to the user by contacting with a specific portion of the user. In this embodiment, the vibration transmission layer 215 is further connected to the earphone housing 212 to cover the opening 2121 of the accommodating cavity 2122, so as to protect the devices in the accommodating cavity 2122 of the earphone housing 212 to a certain extent. Specifically, the vibration transmission layer 215 may be connected to the earphone housing 212 by plugging, fastening, and bonding, and the vibration transmission layer 215 may be fastened to the periphery of the earphone housing 212 by fastening.

In an application scenario, the vibration transmission plate 214 is made of a hard material, for example, hard plastic, so as to better conduct vibration signals, the vibration transmission layer 215 is made of a soft material, for example, soft silica gel, and is coated on the outer surface of the vibration transmission plate 214, so that the bone conduction earphone further transmits vibration signals to a user through the vibration transmission layer 215, and the user has better touch feeling when using the bone conduction earphone.

It should be noted that, in this embodiment, the vibration transmission layer 215 is coated on the outer surface of the vibration transmission plate 214 in an integral injection molding manner, so that the vibration transmission layer 215 and the vibration transmission plate 214 are in an integral structure, and when the bone conduction headset is assembled, the vibration transmission layer 215 and the vibration transmission plate 214 do not need to be adhered together in a manner of dispensing or the like, so that the assembly steps of the headset can be simplified. Meanwhile, the vibration transmission plate 214 and the vibration transmission layer 215 are of an integrated structure, so that adverse effects on the vibration transmission effect caused by uneven thickness of the adhesive layer between the vibration transmission plate 214 and the vibration transmission layer 215 due to adhesive dispensing can be avoided, the vibration transmission effect is improved, and the sound transmission quality of the bone conduction earphone is further improved.

In one embodiment, the vibration transmitting plate 214 protrudes from the opening 2121 to transmit the vibration signal generated by the transducer 213 in the accommodating cavity 2122 of the earphone housing 212 to the outside of the accommodating cavity 2122 and further to the user through the vibration transmitting layer 215.

The vibration transmission layer 215 is fully adhered to the portion of the outer surface of the vibration transmission plate 214 exposed through the opening 2121, and is integrally injection-molded. Specifically, in an application scenario, the portion of the outer surface of the vibration transmission plate 214 exposed through the opening 2121 is an arc surface protruding away from the accommodating cavity 2122, and correspondingly, the vibration transmission layer 215 is formed by fully attaching and integrally injection molding the arc surface and the vibration transmission plate 214. It should be noted that, if the vibration transmission plate 214 and the vibration transmission layer 215 are fully bonded by dispensing, firstly, it is difficult to control uniformity of the formed adhesive layer due to the influence of air, dispensing technology, etc., as described above, so that the vibration transmission effect is reduced; secondly, if carry out full laminating through the mode of point gum, then because in order to realize full laminating, the point gum is easy excessive to spill over, on the one hand further reduces the homogeneity of glue film, on the other hand still brings inconvenience for the assembly of earphone. In this embodiment, the vibration transmission plate 214 and the vibration transmission layer 215 are fully bonded together by means of integral injection molding, so that adverse effects caused by the full bonding realized by the dispensing can be avoided, and on one hand, the bonding area of the vibration transmission layer 215 and the vibration transmission plate 214 can be increased, so that the vibration transmission effect is improved, and on the other hand, the contact area of the vibration transmission layer 215 and the skin of a user can be increased due to the arrangement of the cambered surface, so that the vibration transmission effect is further improved. Specifically, the portion of the outer surface of the vibration-transmitting plate 214 exposed through the opening 2121 may be a plane at the middle portion, and a cambered surface at the peripheral portion.

In one embodiment, the vibration transmitting plate 214 is spaced apart from the earphone housing 212 at the opening 2121 to form an annular space around the vibration transmitting plate 214, and the vibration transmitting layer 215 is provided with through holes 2151 at corresponding areas of the annular space.

In this embodiment, the vibration plate 214 is not connected to the earphone housing 212, specifically, at the opening 2121, the inner side edge of the earphone housing 212 and the outer side edge of the vibration plate 214 are both circular or similar to circular, so that the earphone housing 212 and the vibration plate 214 together form an annular spacer.

The vibration transmission layer 215 is disposed on the outer surface of the vibration transmission plate 214 and is connected to the earphone housing 212 to cover the opening 2121 of the accommodating cavity 2122, so that the direction of the annular spacer away from the accommodating cavity 2122 is covered by the vibration transmission layer 215.

In the present embodiment, the through holes 2151 are further provided in the region of the vibration transmission layer 215 corresponding to the annular spacer, specifically, the shape of the through holes 2151 may be circular, elliptical, or the like, and the number may be one or more, which is not limited herein. When a plurality of through holes 2151 are provided, they may be spaced around vibration plate 214.

It should be noted that, in this embodiment, the through hole 2151 is provided to enable the accommodating cavity 2122 to communicate with the outside of the earphone housing 212, so that leakage sound is further reduced by vibration cancellation, and thus the sound conduction effect of the bone conduction earphone is further improved.

The foregoing is only the embodiments of the present application, and not the patent scope of the present application is limited by the foregoing description, but all equivalent structures or equivalent processes using the contents of the present application and the accompanying drawings, or directly or indirectly applied to other related technical fields, which are included in the patent protection scope of the present application.
