The frame and the leg of the smart glasses are usually connected by a hinge structure to realize the relative rotation between the leg and the frame. The hinge needs to be as light as possible on the basis of having a rotating shaft function to avoid excessive weight of the whole machine. At the same time, due to the limited space of the leg, the volume of the hinge also needs to be as small as possible. Therefore, how to effectively design the hinge structure to be light and small is a problem that needs to be solved by the technical personnel in the field at present.

[0049] The embodiments of the present application disclose a hinge structure and smart glasses to reduce the space occupation of the hinge structure and reduce the weight of the hinge structure.

[0050] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0051] The hinge structure provided by the present application can be used for the rotary connection between two connecting pieces, and is particularly applicable to, but not limited to, the connection between the leg and the frame of smart glasses. The rotary axis of the conventional hinge structure is fixed when rotating, and the present application provides a hinge structure, the first rotary piece and the second rotary piece can rotate relative to each other to realize the rotary connection between the two connecting pieces connected with the first rotary piece and the second rotary piece respectively, and the rotary axis of the first rotary piece and the second rotary piece when rotating relative to each other can move linearly.

[0052] In some embodiments, referring to Figs. 1-2, the hinge structure provided by the present application comprises a first rotating member 1, a second rotating member 2, a connecting member 3 and an elastic member 4. The first rotating member 1 and the second rotating member 2 are two main structures for relative rotation of the hinge structure. One of the first rotating member 1 and the second rotating member 2 can be used to connect with the temple of the smart glasses, and the other can be used to connect with the frame of the smart glasses. The temple is folded or unfolded relative to the frame through the relative rotation of the first rotating member 1 and the second rotating member 2. A limiting through hole 21 is formed on the second rotating member 2, and one end of the connecting member 3 is rotatably arranged on the first rotating member 1, and the other end is arranged through the limiting through hole 21. Specifically, one end of the connecting member 3 is rotatably connected with the first rotating member, and the other end is slidably connected with the second rotating member. The first rotating member 1 and the connecting member 3 can rotate relative to each other, and the connecting member 3 can move linearly along the limiting through hole 21, so that the first rotating member 1 and the second rotating member 2 can be relatively flipped, and the rotation axis during flipping moves linearly, i.e., the first rotating member 1 and the second rotating member 2 no longer rotate around a fixed rotation axis as the center during flipping. Specifically, the first rotating member 1 and the second rotating member 2 can rotate relative to each other around the rotation axis of the first rotating member 1 and the connecting member 3 which moves linearly. The elastic member 4 is arranged between the connecting member 3 and the second rotating member 2. When the first rotating member 1 and the second rotating member 2 are relatively flipped, the connecting member 3 moves linearly correspondingly, so that the connecting member 3 acts on the elastic member 4 to make it elastically deform to provide a restoring force. Since the elastic member 4 is arranged between the connecting member 3 and the second rotating member 2, the force of the elastic member 4 acts on the second rotating member 2 at the same time, so that the second rotating member 2 can abut against the first rotating member 1. In this embodiment, the connecting member 3 and the elastic member 4 cooperate with the first rotating member 1 and the second rotating member 2. The limiting through hole 21 is used to limit the degrees of freedom of the connecting member 3, so that it can only move linearly along the limiting through hole 21. That is, when the first rotating member 1 and the second rotating member 2 are relatively flipped, the connecting member 3 can only move linearly along the limiting through hole 21, so as to ensure that the connecting member 3 has a determined motion track. In addition, the connecting member 3 and the elastic member 4 cooperate to ensure that the first rotating member 1 and the second rotating member 2 cannot move up and down in the direction perpendicular to the limiting through hole 21, thereby ensuring that the hinge structure as a whole has a unique determined motion track.

[0053] The hinge structure provided in the application is used, one end of the connecting piece 3 is rotatably arranged on the first rotating piece 1, the other end is arranged in the limiting through hole 21, and the elastic piece 4 acts on the second rotating piece 2. When the first rotating piece 1 and the second rotating piece 2 are relatively flipped, on one hand, the first rotating piece 1 rotates relative to the connecting piece 3, and at the same time, the connecting piece 3 moves linearly relative to the second rotating piece 2 along the limiting through hole 21, that is, when the first rotating piece 1 and the second rotating piece 2 are relatively flipped, it is rotated around the linearly moving rotation axis, so that the hinge structure can meet the flipping requirement through a smaller size, and enough space is left for the distribution of other structural members of the smart glasses provided with the hinge structure, thereby reducing the overall size of the smart glasses. In addition, the size is reduced, and the weight is correspondingly reduced, thereby facilitating the miniaturization and lightweight design.

[0054] In some embodiments, the appearance gap of the hinge structure is zero when it is flipped. Since the rotation center is not fixed when it is flipped, the first rotating piece 1 and the second rotating piece 2 form a line-plane cooperation or a plane-plane cooperation, that is, the first rotating piece 1 and the second rotating piece 2 always remain in close contact, achieving the goal of zero appearance gap. Specifically, referring to FIGS. 1-6, during the flipping process of the first rotating piece 1 and the second rotating piece 2, the first rotating piece 1 and the second rotating piece 2 are in line contact or surface contact. It can be understood that, since the rotation axes of the first rotating piece 1 and the second rotating piece 2 can always move linearly during the flipping process, according to the structure of the first rotating piece 1 and the second rotating piece 2, they can always remain in line contact during the relative flipping process, or in some angles for surface contact, and always remain in line contact in the remaining angles. Therefore, from the appearance, the first rotating piece 1 and the second rotating piece 2 always remain in close contact, and when the hinge structure connects the temple and the frame, the temple and the frame always remain in close contact, ensuring that they are tightly close at any flipping angle, significantly improving the appearance of the overall structure, and eliminating the need for additional shielding components to shield the hinge structure, thereby simplifying the structure.

[0055] In some embodiments, referring to FIGS. 1-6, the first rotating piece 1 is provided with a first plane 11 at one end facing the second rotating piece 2, the first plane 11 is parallel to the rotation axis of the first rotating piece 1 and the connecting piece 3, and the second rotating piece 2 is provided with a second plane 22 parallel to the first plane 11 to be in surface contact with the first plane 11. By providing the first plane 11 and the second plane 22, the first rotating piece 1 and the second rotating piece 2 can be flipped to surface contact, that is, the first plane 11 is in contact with the second plane 22, and the elastic piece 4 can provide a force to the second rotating piece 2, so that the hinge structure can be stably maintained in the current state to meet the regular use of the hinge structure. Specifically, when the first rotating piece 1 and the second rotating piece 2 are connected with the temple and the frame respectively, the state of the first plane 11 being in contact with the second plane 22, the temple is opened.

[0056] In some embodiments, referring to FIG. 1-4, the outer edge of the first plane 11 is provided with an arc surface 12 to be in line contact with the second plane 22 when the first rotating member 1 and the second rotating member 2 are relatively turned outward. It is to be noted that the outer side here refers to the direction in which the first rotating member 1 and the second rotating member 2 are turned to one side from the state in which the first plane 11 and the second plane 22 are in contact, and the inner side accordingly refers to the direction in which the first rotating member 1 and the second rotating member 2 are turned to the other side. In the case in which the hinge structure is connected to the temple and the frame, the outer side refers to the direction in which the temple is turned outward relative to the frame, and the inner side accordingly refers to the direction in which the temple is turned inward relative to the frame. By providing the arc surface 12 on the outer edge of the first plane 11, on the one hand, the arc surface 12 can be in line contact with the second plane 22 when the first rotating member 1 and the second rotating member 2 are relatively turned outward, thereby avoiding the generation of a gap between the first rotating member 1 and the second rotating member 2 when turned. On the other hand, the provision of the arc surface 12 makes it easier for the user to turn the first rotating member 1 or the second rotating member 2, and the arc surface 12 generates rolling friction when the first rotating member 1 and the second rotating member 2 are relatively turned, which is smaller than sliding friction, and thus is less likely to be worn.

[0057] In some embodiments, referring to FIG. 5-6, the first rotating member 1 is further provided with a third plane 13, and the first rotating member 1 and the second rotating member 2 can be relatively turned inward from the state in which the first plane 11 and the second plane 22 are in contact to the state in which the third plane 13 and the second plane 22 are in contact. By providing the third plane 13, the first rotating member 1 and the second rotating member 2 can be turned to face contact, i.e., the third plane 13 and the second plane 22 are in contact, and the elastic member 4 can provide a force to the second rotating member 2, thereby enabling the hinge structure to be stably maintained in the current state to meet another regular use state of the hinge structure. That is, in this embodiment, the first rotating member 1 and the second rotating member 2 can be maintained in the state in which the first plane 11 and the second plane 22 are in contact under the action of the elastic member 4, when turning is needed, an external force is applied to the first rotating member 1 and / or the second rotating member 2 to relatively turn the first rotating member 1 and the second rotating member 2 inward, and when the third plane 13 and the second plane 22 are in contact, the first rotating member 1 and the second rotating member 2 can be maintained in the current state under the action of the elastic member 4. In the process of turning from the state in which the first plane 11 and the second plane 22 are in contact to the state in which the third plane 13 and the second plane 22 are in contact, the first rotating member 1 can always be in line contact with the second plane 22. Specifically, when the first rotating member 1 and the second rotating member 2 are connected to the temple and the frame respectively, in the state in which the third plane 13 and the second plane 22 are in contact, the temple is folded relative to the frame. The angle between the first plane 11 and the third plane 13 can be set as needed, e.g., the two planes can be perpendicular, and according to the needs of the use scenario, the angle can be 60 degrees, 100 degrees, or other angles.

[0058] In some embodiments, referring to FIGS. 5-6, the third plane 13 and the first plane 11 are connected by an arc surface. By arranging the arc surface between the third plane 13 and the first plane 11, on one hand, when the first rotating member 1 and the second rotating member 2 are relatively turned inward, the arc surface can be in line contact with the second plane 22, avoiding the generation of a gap between the first rotating member 1 and the second rotating member 2 during turning. On the other hand, the arrangement of the arc surface makes the operation more labor-saving when the user turns the first rotating member 1 or the second rotating member 2, and the arc surface transition generates rolling friction when the first rotating member 1 and the second rotating member 2 are relatively turned, which is smaller than the frictional force of sliding friction, and thus is not easy to wear. Of course, in other embodiments, the arc surface can not be arranged, i.e., the first plane 11 and the third plane 13 can also be straight edges, which can also maintain line contact with the second plane 22.

[0059] In some embodiments, referring to FIGS. 3, 5-6, the third plane 13 and the first plane 11 are connected by a round corner 14, and the radius R of the round corner 14 is inversely related to the maximum restoring force provided by the elastic member 4 to the second rotating member 2. By arranging the round corner 14, when the first rotating member 1 and the second rotating member 2 are turned inward from the state of being in contact with the first plane 11 and the second plane 22, the elastic member 4 is deformed, and the deformation amount of the elastic member 4 is inversely related to the radius R of the round corner 14, i.e., the greater the radius R of the round corner 14, the smaller the maximum deformation amount of the elastic member 4; conversely, the smaller the radius R of the round corner 14, the greater the maximum deformation amount of the elastic member 4. As shown in FIG. 3, in the state of being in contact with the first plane 11 and the second plane 22, the distance between the rotation axis of the first rotating member 1 and the connecting member 3 and the second plane 22 is X1; as shown in FIG. 5, in the process of turning inward, the maximum distance between the rotation axis of the first rotating member 1 and the connecting member 3 and the second plane 22 is X2, then ΔX = X2-X1, and ΔX is the deformation amount of the elastic member 4. The maximum restoring force provided by the elastic member 4 to the second rotating member 2 is determined by ΔX, and thus the size of the radius R of the round corner 14 can be arranged to adjust the maximum restoring force provided by the elastic member 4 to the second rotating member 2 when turning inward, i.e., the radius R can be changed to adjust the elastic arch effect force value of the hinge structure, which is convenient to adjust without the need to replace the elastic member 4 or to disassemble and modify the entire hinge structure.

[0060] The above embodiments respectively illustrate the cases of the first rotating member 1 and the second rotating member 2 being relatively turned inward and outward. When the first rotating member 1 and the second rotating member 2 are turned inward and outward from the state of being in contact with the first plane 11 and the second plane 22, the connecting member 3 can act on the elastic member 4 to deform it, so that the restoring force of the elastic member 4 can act on the second rotating member 2, i.e., the automatic resetting force of the second rotating member 2. When the hinge structure is connected between the temple and the frame, it can provide the automatic resetting force for the temple, and when the temple is turned outward, it can provide the clamping force of the temple, so that it can be reliably fitted to the user's head.

[0061] According to actual needs, the turning of the first turning member 1 and the second turning member 2 in the above embodiments can only include outward turning, i.e. turning from the state of contact between the first plane 11 and the second plane 22 to the outward turning; or can only include inward turning, i.e. turning from the state of contact between the first plane 11 and the second plane 22 to the outward turning; or can include both inward turning and outward turning. In the state without the first plane 11 and the second plane 22, the inward turning and the outward turning correspond to forward turning and reverse turning respectively.

[0062] In some embodiments, referring to FIGS. 1-6, the connecting member 3 includes a connecting member body 31 and a blocking member 32. The connecting member body 31 is arranged through the limiting through hole 21, and one end is rotatably arranged at the first turning member 1. The blocking member 32 is arranged at the other end of the connecting member body 31, and the elastic member 4 is arranged between the blocking member 32 and the second turning member 2. It can be understood that the blocking member 32 and the connecting member body 31 can be an integrated structure or a split structure connected by a conventional fixing mode. The blocking member 32 is opposite to the second turning member 2 to facilitate the installation of the elastic member 4, such as abutting the two ends of the elastic member 4 to the second turning member 2 and the blocking member 32 respectively. When the first turning member 1 and the second turning member 2 are turned relative to each other, the connecting member body 31 moves along the limiting through hole 21, and the blocking member 32 acts on the elastic member 4 to compress or release it.

[0063] In some embodiments, the elastic member 4 includes a spiral spring, and the spiral spring can be sleeved outside the connecting member body 31. Thus, the connecting member body 31 can support and guide the spiral spring to deform more stably. In other embodiments, the elastic member 4 can also be an elastic material member or an elastic structure member capable of providing a restoring force.

[0064] In some embodiments, the connection between the connecting member 3 and the first turning member 1 is realized by the rotating shaft 6, which simultaneously penetrates the through hole on the first turning member 1 and the through hole on the connecting member 3 to connect the connecting member 3 and the first turning member 1 while allowing the connecting member 3 to rotate around the rotating shaft 6. The connection between the connecting member 3 and the second turning member 2 is realized by the elastic member 4 and the blocking member 32. The connecting member 3 penetrates the limiting through hole 21 of the second turning member 2 and the spiral spring and is then fixed to the blocking member 32. The two ends of the elastic member 4 abut to the second turning member 2 and the blocking member 32, and the blocking member 32 and the elastic member 4 make the connecting member 3 arranged through the limiting through hole 21 and unable to be taken out. The limiting through hole limits the connecting member 3 to move reciprocally in a horizontal manner, and the elastic member 4 specifically maintains a certain pre-pressing amount to ensure that the first turning member 1 and the second turning member 2 always maintain a state of close connection.

[0065] In some embodiments, the first rotating member 1 comprises a first panel 16 and a support 17 arranged on the first panel 16, the connecting member 3 is rotationally connected with the support 17, the first panel 17 is provided with an avoiding slot 15, and the connecting member 3 is arranged in the avoiding slot 15. It can be understood that the first panel 16 and the support 17 can be an integrated structure or a split structure connected by a conventional fixing mode. The support 17 is rotationally connected with the connecting member 3, and in the case that the connecting member 3 comprises a connecting member main body 31 and a blocking member 32, one end of the connecting member main body 31 is rotationally connected with the support 17. The avoiding slot 15 can be in a strip shape, and one end thereof can extend to the edge of the first panel 16, i.e., in an opening, so as to facilitate the assembly of the connecting member 3. When the first rotating member 1 and the second rotating member 2 are relatively flipped, the connecting member 3 moves linearly along the limiting through hole 21, and the connecting member 3 rotates relative to the support 17 about the rotation axis, so that the connecting member 3 can move in the avoiding slot 15, thereby avoiding movement interference.

[0066] Further, the first rotating member 1 and the second rotating member 2 can be relatively outward flipped to abut against one end of the connecting member 3 and the avoiding slot 15. That is, the outward flipping angle of the first rotating member 1 and the second rotating member 2 is limited by the cooperation of the avoiding slot 15 and the connecting member 3, so as to avoid that the outward flipping angle is too large. Specifically, the outward limit angle of the first rotating member 1 and the second rotating member 2 is set to 20-30 degrees.

[0067] In other embodiments, the limiting of the outward flipping angle of the first rotating member 1 and the second rotating member 2 can also be achieved by arranging a limiting structure on the second rotating member 2 to cooperate with the connecting member 3. In the case that the connecting member 3 comprises a connecting member main body 31 and a blocking member 32, a limiting part is arranged on the second rotating member 2 opposite to the blocking member 32. When the first rotating member 1 and the second rotating member 2 are relatively outward flipped, the blocking member 32 moves linearly close to the limiting part until the blocking member 32 abuts against the limiting part, so that the further outward flipping of the first rotating member 1 and the second rotating member 2 is limited, i.e., the outward limit angle is reached.

[0068] In some embodiments, referring to FIG. 2 or FIGS. 7-9, the hinge structure comprises at least two connecting members 3, and the two connecting members 3 are arranged at intervals and are respectively rotationally connected with the first rotating member 1 through two rotating shafts 6. By arranging two connecting members 3 to cooperate with the first rotating member 1 and the second rotating member 2, the flipping cooperation of the two rotating members is more stable and reliable. Moreover, the two connecting members 3 are respectively connected with the first rotating member 1 through separately arranged rotating shafts 6, thereby avoiding the use of a long rotating shaft and reducing the overall weight. Specifically, the first rotating shaft 6 is rotationally connected with the first connecting member 3 from the outer end thereof away from the second connecting member 3, and the second rotating shaft 6 is rotationally connected with the second connecting member 3 from the outer end thereof away from the first connecting member 3.

[0069] In some embodiments, referring to Figs. 7-9, the hinge structure comprises an electrical connecting member 5 arranged in the space between the two rotating shafts 6 and extending to the first rotating member 1 and the second rotating member 2 respectively to connect the electrical elements in the temple and the frame of the smart glasses. By arranging the electrical connecting member 5, the electrical elements in the frame and the temple are connected to realize the corresponding power supply and / or communication functions. It can be understood that the electrical elements include but are not limited to flexible circuit board, rigid circuit board, spring, pin, etc. The electrical connecting member 5 can be a flexible circuit board, a wire, etc. The two rotating shafts 6 and the two connecting members 3 are arranged in space, which provides a wire passing space for the electrical connecting member 5. The wire passing space can be designed without shaft, i.e. no physical rotating shaft is arranged in the wire passing space, and the electrical connecting member 5 can directly pass through the rotating axis of the first rotating member 1 and the connecting member 3. Therefore, when the hinge structure is flipped, the length of the electrical connecting member 5 changes the least in the corresponding bending process, which greatly improves the service life of the electrical connecting member 5. On the other hand, the structure allows the electrical connecting member 5 to be arranged in the hinge structure after the hinge structure is installed, which is simple to assemble and is not affected by the size of the electrical connecting member 5 connector, and has low assembly requirements.

[0070] In some embodiments, referring to Fig. 10, one of the first rotating member 1 and the second rotating member 2 is used to connect with the frame of the smart glasses, and the other is used to connect with the temple of the smart glasses; the four peripheral side walls of the first rotating member 1 and the side walls of the connecting end of the frame or the temple connected therewith are flush, and / or the four peripheral side walls of the second rotating member 2 and the side walls of the connecting end of the frame or the temple connected therewith are flush. That is, after the first rotating member 1 is assembled with the corresponding connecting end, the four peripheries of the first rotating member 1 are flush with the four peripheries of the corresponding connecting end. Correspondingly, after the second rotating member 2 is assembled with the corresponding connecting end, the four peripheries of the second rotating member 2 are flush with the four peripheries of the corresponding connecting end. The end faces of the first rotating member 1 and the second rotating member 2 are used as the appearance surface of the hinge structure while being used as the movement contact surface, which on the one hand makes the hinge structure not embedded in the corresponding connecting end (such as a plastic shell), reduces the precision requirement, avoids the appearance from having a step difference, and ensures the integrity and aesthetics of the appearance. On the other hand, the end faces of the hinge structure are arranged as the appearance surface, specifically the first plane 11 and the second plane 22 as the appearance surface, which provides a larger contact area, reduces the wear, and prolongs the service life of the hinge structure.

[0071] In some embodiments, referring to FIG. 2, the first rotating member 1 includes a first panel 16 and a support 17. The first panel 16 is configured to cooperate with the second rotating member 2, and the first panel 16 is provided with a clearance slot 15 in which the connecting member body 31 is arranged. The support 17 is provided with a through hole, and the connecting member body 31 specifically includes a connecting rod 312 and a connecting ring 311 arranged at the end of the connecting rod 312. The hollow part of the connecting ring 311 is opposite to the through hole, and the rotating shaft 6 is arranged in the through hole and the connecting ring 311 to rotationally connect the connecting member body 31 and the support 17. In the case that the first rotating member 1 is provided with at least one of the first plane 11, the third plane 13, the arc surface 12, and the rounded corner 14, the at least one is arranged on the first panel 16. When the first rotating member 1 is assembled on the temple or the frame, the side wall around the first panel 16 is flush with the side wall around the connecting end on the corresponding temple or frame. The support 17 is specifically provided with a first fixing part, such as a screw hole, to be screwed with the corresponding connecting end. The first fixing part is specifically arranged on the part of the support 17 perpendicular to the first panel 16 to more fully utilize the space and thereby reduce the space occupation of the hinge structure. In summary, the first rotating member 1 is provided with the above arrangement, which is simple and compact in structure, facilitates cooperation and connection with various components, is reliable in overall structural connection, stable in movement, and small in space occupation.

[0072] In some embodiments, referring to FIG. 2, the second rotating member 2 includes a second panel 23 and a support lug 24. The second panel 23 is configured to cooperate with the first rotating member 1, and the limiting through hole 21 is arranged on the second panel 23. The support lug 24 is arranged on the second panel 23. In the case that the second rotating member 2 is provided with the second plane 22, the second plane 22 is arranged on the second panel 23. When the second rotating member 2 is assembled on the temple or the frame, the side wall around the second panel 23 is flush with the side wall around the connecting end on the corresponding temple or frame. The support lug 24 is provided with a second fixing part, such as a screw hole, to be screwed with the corresponding connecting end. The support lug 24 is specifically perpendicular to the second panel 23 to more fully utilize the space and thereby reduce the space occupation of the hinge structure.
