Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0032] Augmented Reality (AR) is a technology that calculates the position and angle of camera images in real time and adds corresponding images. The goal of this technology is to overlay the virtual world on the real world on the screen and interact with it. AR glasses are products generated under this technology. AR glasses usually include frames and temples. The temples are connected to the frames through a hinge mechanism for users to use. However, the rotating part connected to the temples in the traditional hinge mechanism usually does not have the function of automatically resetting after rotation.

[0033] In order to improve the problem that the traditional rotating shaft mechanism has no automatic reset function after the rotating part rotates, the utility model provides a rotating shaft mechanism.

[0034] Please refer to Figure 1 and Figure 2 In one embodiment of the utility model, the rotating shaft mechanism includes a support frame assembly 100, a rotating assembly 300 and an elastic member 400. The support frame assembly 100 includes a first side bracket 110 and a second side bracket 120 which are separately arranged; both ends of the rotating assembly 300 are rotatably connected to the first side bracket 110 and the second side bracket 120 respectively; the elastic member 400 is connected to the rotating assembly 300, and the elastic member 400 can limit the rotation of the rotating assembly 300, and can reset the rotating assembly 300 after the rotating assembly 300 rotates.

[0035] The support frame assembly 100 includes a first side bracket 110 and a second side bracket 120 which are separately arranged, which means that the support frame assembly 100 is composed of at least two independent parts, wherein the two independent parts are the first side bracket 110 and the second side bracket 120, that is, the first side bracket 110 and the second side bracket 120 are not connected by a connecting piece. With such an arrangement, the overall weight of the support frame assembly 100 is relatively light, so that when the shaft mechanism is applied to a head-mounted device, such as between the frame and the temples of glasses, the pressure of the head-mounted device on the user's head can be reduced. In addition, such an arrangement can also reduce the material cost of the support frame assembly 100.

[0036] The rotating assembly 300 refers to an assembly that can rotate relative to the support frame assembly 100100. When the shaft mechanism is applied to glasses, the rotating assembly 300 can be connected to the temples, so that the temples can be folded, and the opening and closing angles of the temples can be adjusted. By rotating the two ends of the rotating assembly 300 to the first side bracket 110 and the second side bracket 120, the rotating assembly 300 can rotate relative to the support frame assembly 100, and has a good connection effect with the support frame assembly 100. Specifically, when the two ends of the rotating component 300 are respectively rotatably connected to the first side bracket 110 and the second side bracket 120, the rotating component 300 can be arranged between the first side bracket 110 and the second side bracket 120; or one end of the rotating component 300 can be sleeved and matched with the first side bracket 110 or the second side bracket 120, for example, one end of the rotating component 300 is sleeved outside the first side bracket 110 or the second side bracket 120, or the first side bracket 110 or the second side bracket 120 can be sleeved outside one end of the rotating component 300; or, the two ends of the rotating component 300 are respectively sleeved and matched with the first side bracket 110 and the second side bracket 120.

[0037] The rotating mechanism also includes an elastic member 400, which is connected to the rotating assembly 300. The elastic member 400 limits the rotation of the rotating assembly 300 and can reset the rotating assembly 300 after the rotating assembly 300 rotates. Therefore, after the elastic member 400 is added, the rotating mechanism can achieve the effect of automatic reset of the rotating assembly 300 after rotation. Therefore, when the rotating shaft mechanism in the technical solution of the utility model is applied between the frame and the temples of the glasses and the temples are connected to the rotating assembly 300, the user can open the temples and wear the glasses to achieve the effect of automatically clamping the user's head with the temples. On the one hand, it reduces the risk of the glasses falling off, and on the other hand, it allows the glasses to be adapted to users with different face shapes. Specifically, the elastic member 400 may be a spring or a torsion spring. When the elastic member 400 is a spring, a supporting portion that is mutually limited with the spring may be provided on the rotating assembly 300. The supporting portion is driven to rotate during the rotation of the rotating assembly 300, and then the supporting portion compresses and deforms the spring. When the driving force for the rotation of the rotating assembly 300 is removed, the spring drives the rotating assembly 300 to reset under the action of its elastic force. When the elastic member 400 is a torsion spring, one end of the torsion spring is connected to the rotating assembly 300 and rotates synchronously with the rotating assembly 300, and the other end is fixedly connected to the support frame assembly 100, so that when the rotating assembly 300 rotates, the torsion spring is driven to torsion and deform. When the driving force for the rotation of the rotating assembly 300 is removed, the torsion spring drives the rotating assembly 300 to reset under the action of its elastic force. In this way, the rotating assembly 300 has the function of automatically resetting after rotation.

[0038] The support frame assembly 100 in the technical solution of the utility model includes a first side bracket 110 and a second side bracket 120 which are separately arranged, so that the structure of the support frame assembly 100 is relatively simple, the weight of the support frame assembly 100 is relatively light, the overall weight of the rotating shaft mechanism is reduced, and the material cost of the support frame assembly 100 is reduced. By rotating and connecting the two ends of the rotating assembly 300 to the first side bracket 110 and the second side bracket 120 respectively, the rotating assembly 300 can be rotated relative to the support frame assembly 100. By connecting the elastic member 400 to the rotating assembly 300, the elastic member 400 limits the rotation of the rotating assembly 300, and can reset the rotating assembly 300 after the rotating assembly 300 rotates, so that the rotating assembly 300 can be hindered by the elastic member 400 during the rotation process, so that on the one hand, the rotation of the rotating assembly 300 can be limited, and it can also be realized that after the rotation force on the rotating assembly 300 is removed, the rotating assembly 300 is automatically reset under the elastic force of the elastic member 400, thereby increasing the function that the rotating part of the rotating shaft mechanism can automatically reset.

[0039] like Figure 1 As shown, in some embodiments of the present invention, one end of the rotating assembly 300 is sleeved outside the first side bracket 110 or the second side bracket 120 .

[0040] By sleeved one end of the rotating assembly 300 outside the first side bracket 110 or the second side bracket 120, the rotating assembly 300 can protect part of the first side bracket 110 or the second side bracket 120, and can also reduce the large space occupied by the rotating shaft mechanism in the rotating shaft direction of the rotating assembly 300.

[0041] Please refer to Figure 2 As shown, in one embodiment of the present invention, the rotating shaft mechanism may further include a shaft body 200 , and the shaft body 200 is installed on the supporting frame assembly 100 .

[0042] The rotating assembly 300 can rotate with the center line of the shaft body 200 as the axis. Specifically, the shaft body 200 can be provided with one, and the two ends of the shaft body 200 are respectively connected to the first side bracket 110 and the second side bracket 120. Or the shaft body 200 can be provided with two, the two shaft bodies 200 are coaxially arranged side by side, and the two shaft bodies 200 are respectively connected to the first side bracket 110 and the second side bracket 120. Specifically, the shaft body 200 can be detachably connected to the support frame assembly 100, so as to facilitate the shaft body 200 to be replaced separately and the support frame assembly 100 to be replaced separately. For example, the first side bracket 110 and the second side bracket 120 are both provided with a through hole for inserting the shaft body 200, and the two ends of the shaft body 200 are respectively inserted into the through hole of the first side bracket 110 and the through hole of the second side bracket 120. Or the shaft body 200 can be fixedly connected to the first side bracket 110 and / or the second side bracket 120 through a flange. Alternatively, the shaft body 200 may be connected to the first side bracket 110 and / or the second side bracket 120 by a clamping method. Of course, in other examples, the shaft body 200 may also be non-detachably connected to the support frame assembly 100, for example, the shaft body 200 and the support frame assembly 100 are welded or integrally formed to achieve a non-detachable connection effect, thereby enhancing the support strength of the support frame assembly 100 and the shaft body 200.

[0043] Please refer to Figure 2 As shown, in some embodiments of the present invention, the second side bracket 120 is provided with a first limiting portion 120a, and the elastic member 400 is a torsion spring, one end of the torsion spring is connected to the rotating assembly 300, and the other end is mutually abutted against the first limiting portion 120a and the torsion spring is twisted and deformed to limit the rotation of the rotating assembly 300 and to reset the rotating assembly 300 after the rotating assembly 300 rotates.

[0044] When the rotating assembly 300 rotates, the elastic member 400 also rotates synchronously with the rotating assembly 300. When the elastic member 400 is a torsion spring, one end of the torsion spring will abut against the first limit portion 120a on the support frame assembly 100, and the first limit portion 120a will limit the movement of the end of the torsion spring abutting against the first limit portion 120a. However, the end of the torsion spring connected to the rotating assembly 300 will deform under the continued rotation of the rotating assembly 300, so that the torsion spring is in a state of torsion deformation, and the torsion spring has no effect on the rotating assembly 300. Continued rotation will have an hindering effect. When the rotational driving force on the rotating component 300 is cancelled, the rotating component 300 will tend to reverse to the initial state under the action of the torsion spring. Therefore, when the temple is connected to the rotating component 300, and the torsion spring and the first limiting portion 120a are in abutment against each other and the torsion spring is in a torsional deformation state (this state is defined as the rotating component 300 being in an elastic clamping state), the torsion spring can provide the temple with a clamping force when worn, so that it can automatically clamp the user's face and adapt to users with different face shapes.

[0045] Please refer to Figure 1 and Figure 3 In some embodiments of the present invention, the rotating assembly 300 also has a transition state when rotating relative to the support frame assembly 100. In the transition state, the end of the torsion spring away from the rotating wheel 310 is mutually limited by the first limiting portion 120a and is not compressed or torsionally deformed.

[0046] The rotating wheel 310 also has a transition state when rotating relative to the support frame assembly 100, and the transition state is an intermediate state when transitioning from the self-locking state to the elastic clamping state or an intermediate state when transitioning from the elastic clamping state to the self-locking state. In the transition state, the end of the torsion spring away from the rotating wheel 310 is mutually limited with the first limit portion 120a, but the torsion spring does not undergo torsional deformation. At this time, if the rotating assembly 300 rotates toward the above-mentioned elastic clamping state, the torsion spring can be abutted against the first limit portion 120a and the torsion spring will undergo torsional deformation. By setting the transition state, the rotating assembly 300 can be in a transition state without using the rotating shaft mechanism, so as to avoid the torsion spring being in a deformed state for a long time and shortening the service life of the torsion spring.

[0047] Please refer to Figure 4 and Figure 5 In one embodiment of the utility model, the rotating assembly 300 includes a rotating wheel 310 that rotates relative to the supporting frame assembly 100, and one end of the elastic member 400 is transmission-connected to the rotating wheel 310. The rotating wheel 310 has a self-locking state when rotating relative to the supporting frame assembly 100; in the self-locking state, the elastic member 400 can also be compressed and deformed along the axial direction of the rotating wheel 310 and squeeze the rotating wheel 310 so that the rotating wheel 310 is against the first side bracket 110.

[0048] The rotating assembly 300 includes a rotating wheel 310, which can be sleeved outside the shaft body 200, so that the rotating wheel 310 can rotate around the center line of the shaft. Alternatively, the rotating wheel 310 can be sleeved outside the first side bracket 110 and rotate around the first side bracket 110 as the shaft.

[0049] The elastic member 400 is in transmission connection with the rotating wheel 310. When the rotating wheel 310 rotates relative to the support frame assembly 100, it has a self-locking state. In the self-locking state, the elastic member 400 is compressed and deformed along the axial direction of the rotating wheel 310 and squeezes the rotating wheel 310, so that the rotating wheel 310 abuts against the first side bracket 110, so that there is sufficient friction between the rotating wheel 310 and the first side bracket 110, thereby reducing the risk of the rotating wheel 310 rotating, and realizing the self-locking state of the rotating wheel 310. Specifically, in order to realize that the rotating wheel 310 can make the elastic member 400 have the effect of compressing and deforming along the axial direction of the rotating wheel 310 during the rotation process, the rotating wheel 310 and the elastic member 400 can be connected by transmission assembly, that is, the elastic member 400 can be compressed and deformed under the drive of the transmission assembly. For example, the rotating wheel 310 and the elastic member 400 are arranged along the axial direction of the rotating wheel 310, and a gear that rotates synchronously with the rotating wheel 310 is further provided at one end of the elastic member 400 away from the rotating wheel 310, and the gear is meshed with a rack, and the rack is connected to the end of the elastic member 400 away from the rotating wheel 310; when the rotating wheel 310 rotates, the gear rotates synchronously with the rotating wheel 310, and the gear can drive the rack to squeeze the elastic member 400 in the direction close to the rotating wheel 310, and then the rotating wheel 310 moves closer to the support frame under the elastic force of the elastic member 400. The rotating wheel 310 and the supporting frame assembly 100 move in the direction of or have a tendency to move toward the direction close to the supporting frame assembly 100, thereby causing the rotating wheel 310 and the supporting frame assembly 100 to abut against each other, increasing the pressure between the rotating wheel 310 and the supporting frame assembly 100, thereby increasing the maximum static friction between the rotating wheel 310 and the supporting frame assembly 100, so that the rotating wheel 310 can achieve a self-locking state, that is, the rotating wheel 310 will not rotate automatically without the action of external force, thereby reducing the risk of the rotating part of the rotating mechanism being prone to automatic fall back. When the supporting frame assembly 100 includes a first side bracket 110 and a second side bracket 120, the rotating wheel 310, the elastic member 400, and the gear can all be arranged between the first side bracket 110 and the second side bracket 120; the rotating wheel 310 can be arranged close to the first side bracket 110. Alternatively, at least one end of the shaft body 200 may extend out of the support frame assembly 100, the rotating wheel 310 may be arranged close to the first side bracket 110 and located on a side of the first side bracket 110 away from the second side bracket 120, and the elastic member 400 is arranged on a side of the rotating wheel 310 away from the first side bracket 110.

[0050] When the wheel 310 rotates relative to the support frame assembly 100, the raised structure on the wheel 310 and the raised structure on the first side bracket 110 of the support frame assembly 100 are in a state of mutual resistance. At this time, the wheel 310 can slide on the shaft body 200 along the extension and contraction direction of the elastic member 400, and the elastic member 400 can be compressed under the action of the raised structure on the support frame assembly 100. The elastic member 400 gives elastic force to the wheel 310 in the reverse direction, so that the raised structure on the wheel 310 and the raised structure on the support frame assembly 100 have a greater resistance force, thereby increasing the friction between the wheel 310 and the support frame assembly 100 and reducing the risk of the wheel 310 automatically falling back.

[0051] In addition, by compressing and deforming the elastic member 400 and squeezing the rotating wheel 310, the arrangement of other friction plates such as butterfly washers can be reduced, thereby simplifying the rotating shaft mechanism and reducing the space occupied by the rotating shaft mechanism.

[0052] Please refer to Figure 6 and Figure 7 In one embodiment of the present invention, the rotating wheel 310 has an initial state when rotating relative to the supporting frame assembly 100. In the initial state, the elastic member 400 is not compressed and deformed, and is spaced apart from the first limiting portion 120a.

[0053] With such arrangement, when the rotating assembly 300 rotates from the initial state to the above-mentioned transition state or elastic clamping state, the elastic member can rotate synchronously with the rotating assembly 300 without being affected by the limiting effect of the first limiting portion 120a, so that the rotating assembly 300 can rotate freely, thereby reducing the rotational resistance of the rotating assembly 300 during the initial rotation, so that the rotating assembly 300 can quickly open to an appropriate angle.

[0054] In order to make the rotating assembly 300 have a self-locking state, please refer to Figure 4 and Figure 5 In some embodiments of the utility model, the rotating wheel 310 is arranged between the first side bracket 110 and the second side bracket 120, and a convex bump 312 is formed on the end surface of the rotating wheel 310 facing the first side bracket 110, and the first side bracket 110 is provided with a protrusion 111; the two ends of the elastic member 400 are respectively connected to the rotating wheel 310 and the second side 120; in the self-locking state, the protrusion 111 is in abutment with the convex bump 312, and the rotating wheel 310 compresses the elastic member 400.

[0055] With such arrangement, when the rotating wheel 310 rotates, the raised portion 111 of the first side bracket 110 is in a state of correspondingly abutting against the convex bump 312 on the rotating wheel 310. At this time, since the raised portion 111 of the first side bracket 110 abuts against the convex bump 312 on the rotating wheel 310, the raised portion 111 will drive the rotating wheel 310 to move in a direction away from the raised portion 111, that is, in the direction of compressing the elastic member 400. At this time, the elastic member 400 is compressed, and the elastic member 400 gives elastic force to the rotating wheel 310 in the opposite direction, so that the rotating wheel 310 is pressed against the raised portion 111 of the first side 110 under the elastic force of the elastic member 400, thereby increasing the friction between the rotating wheel 310 and the first side bracket 110 of the support frame assembly 100, thereby realizing the self-locking state of the rotating wheel 310 and reducing the risk of the rotating wheel 310 automatically falling back when rotating to the self-locking state.

[0056] In addition, in this embodiment, the rotating wheel 310 can not only directly drive the elastic member 400 to be compressed, but also can support the support frame assembly 100 under the elastic force of the elastic member 400. Therefore, in this embodiment, no other transmission components are required to be arranged between the rotating wheel 310 and the elastic member 400, thereby simplifying the structure of the rotating shaft mechanism and reducing the space occupied by the rotating shaft mechanism.

[0057] Based on the above structure, in order to make the rotating wheel 310 have the above initial state, please refer to Figure 4 and Figure 5 In some embodiments of the present invention, a first groove 311 is formed on the end surface of the rotating wheel 310 facing the first side 110 , and the rotating wheel 310 has an initial state when rotating relative to the support frame assembly 100 . In the initial state, the protrusion 111 is located in the first groove 311 .

[0058] By ensuring that the rotating wheel 310 has an initial state when rotating relative to the support frame assembly 100, and in the initial state, the protrusion 111 of the first side 110 of the support frame assembly 100 is located in the first groove 311, the rotating wheel 310 does not compress the elastic member 400, so that the elastic member 400 is in a natural state, reducing the risk of the elastic member 400 being easily failed in the initial state of the rotating shaft mechanism.

[0059] Based on the above structure, in order to make the rotating wheel 310 have the above elastic clamping state, please refer to Figure 3 As shown, in some embodiments of the present invention, a second groove 313 is formed on the end surface of the rotating wheel 310 facing the first side 110 , and when the rotating wheel 310 is in an elastic clamping state, the protrusion 111 slides in the second groove 313 .

[0060] When the rotating wheel 310 rotates to the elastic clamping state, the protrusion 111 is arranged in the second groove 313, which can reduce the degree of the rotating wheel 310 squeezing the elastic member 400, thereby reducing the compression deformation of the elastic member 400, reducing the elastic force of the elastic member 400 on the rotating wheel 310 and the friction between the rotating wheel 310 and the support frame assembly 100, so that the rotating wheel 310 will not self-lock when it is in the elastic clamping state, preventing the rotating wheel 310 from being unable to automatically rebound due to friction during the opening process, thereby affecting the clamping effect of the torsion force of the torsion spring on the rotating wheel 310 and the temple connected to the rotating wheel 310. Specifically, when the rotating wheel 310 has both the first groove 311 and the second groove 313, the first groove 311 and the second groove 313 are arranged at intervals, and the convex bump 312 is arranged between the first groove 311 and the second groove 313.

[0061] Based on the above structure, in the transition state, the protrusion 111 is located in the second groove 313, for example, it can contact the groove wall of the second groove 313 close to the bulge 312. At this time, since the protrusion 111 is located in the second groove 313, the degree of compression deformation of the torsion spring is reduced, so that the torsion spring is no longer in a state of being compressed and deformed by the rotating wheel 310.

[0062] Specifically, when the shaft mechanism is applied to glasses, the glasses include a frame and temples, the frame is connected to the support frame assembly 100, and the temples are connected to the rotating assembly 300. It can be defined that when the temples rotate 0°, that is, when the temples are almost parallel to the lenses in the frame, the rotating wheel 310 is in an initial state; when the temples start to rotate from 0° to a predetermined angle, for example, the predetermined angle can be 90°, and of course it can also be other angles, the rotating wheel 310 is in a self-locking state; when the temples rotate to a predetermined angle, the rotating wheel 310 is in a transition state; when the temples continue to rotate from the predetermined angle to a larger angle, the rotating wheel 310 is in an elastic clamping state.

[0063] like Figure 5 As shown, in some embodiments of the utility model, the support frame assembly 100 is provided with a first arc-shaped limit groove 121, and one end of the torsion spring away from the rotating wheel 310 is arranged in the first arc-shaped limit groove 121. When the rotating wheel 310 is in a self-locking state, the end of the torsion spring away from the rotating wheel 310 can slide in the first arc-shaped limit groove 121.

[0064] It is understandable that when the end of the torsion spring away from the rotating wheel 310 is arranged in the first arc-shaped limiting groove 121, the groove wall of the first arc-shaped limiting groove 121 can limit the angle of the torsion spring rotating synchronously with the rotating wheel 310, so that when the groove wall of the first arc-shaped limiting groove 121 limits the torsion spring, the torsion spring can provide a clamping force for the rotating wheel 310 in an elastic clamping state. In addition, by arranging the end of the torsion spring away from the rotating wheel 310 in the first arc-shaped limiting groove 121, when the rotating wheel 310 is in a self-locking state, the torsion spring has a good guiding and limiting effect when rotating with the rotating wheel 310, and has a good avoidance effect on the movement of the torsion spring rotating synchronously with the rotating wheel 310.

[0065] Please refer to Figure 3 , Figure 5 or Figure 7 As shown, in some embodiments of the present invention, the rotating wheel 310 is provided with an insertion hole 314 , and one end of the elastic member 400 is inserted into the insertion hole 314 .

[0066] By inserting one end of the elastic member 400 into the insertion hole 314 of the rotating wheel 310, it is convenient to connect the elastic member 400 with the rotating wheel 310, thereby improving the connection efficiency between the elastic member 400 and the rotating wheel 310 and reducing the number of connection components.

[0067] Please refer to Figure 1 and Figure 2 , or refer to Figure 4 and Figure 5 In some embodiments of the utility model, the rotating assembly 300 also includes a rotating drum 320, the two ends of which are rotatably connected to the first side bracket 110 and the second side bracket 120 respectively, the rotating wheel 310 is transmission-connected to the rotating drum 320 and rotates synchronously, and at least one of the rotating wheel 310 and the elastic member 400 is located in the rotating drum 320.

[0068] By setting up the rotating drum 320, and at least one of the rotating wheel 310 and the elastic member 400 is located in the rotating drum 320, the rotating wheel 310 is connected to the rotating drum 320 and rotates synchronously. On the one hand, it is convenient for the user to drive the rotating drum 320 to rotate to achieve the effect of driving the rotating wheel 310 to rotate. On the other hand, it also has a good protection effect on at least one of the rotating wheel 310 and the elastic member 400, reducing dust or water vapor from entering between the rotating wheel 310 and the support frame assembly 100 and affecting the contact effect between the rotating wheel 310 and the support frame assembly 100.

[0069] Specifically, the rotating drum 320 may only include a cylindrical drum body, or a connecting ear structure may be connected to the drum body for easy connection with the temples. The rotating wheel 310 is transmission-connected with the rotating drum 320 and rotates synchronously, and the rotating wheel 310 and the rotating drum 320 may be fixedly connected, or a clamping structure is provided on the rotating wheel 310 and the rotating drum 320 to clamp each other.

[0070] Please refer to Figure 1 and Figure 2 , or refer to Figure 4 and Figure 5 In some embodiments of the present invention, one of the rotating drum 320 and the rotating wheel 310 is provided with a slide groove 315, and the other one is provided with a slider, which is inserted into the slide groove 315 and can slide in the slide groove 315. The extension direction of the slide groove 315 is the same as the extension direction of the elastic member 400.

[0071] Specifically, a slide groove 315 may be provided on the inner side wall of the rotating drum 320, and a slider may be provided on the outer side wall of the rotating wheel 310; or a slider may be provided on the inner side wall of the rotating drum 320, and a slide groove 315 may be provided on the outer side wall of the rotating wheel 310. By making the slide groove 315 and the elastic member 400 have the same expansion and contraction direction, the rotating drum 320 can drive the rotating wheel 310 to rotate synchronously during the rotation process, and the rotating wheel 310 can also move along the expansion and contraction direction of the elastic member 400 under the abutment of the protrusion 111 of the support frame assembly 100, so that the rotating wheel 310 can squeeze the elastic member 400 to cause compression deformation in the self-locking state, and the elastic member 400 can reversely give elastic force to the rotating wheel 310, so that the rotating wheel 310 can tightly abut the protrusion 111 of the support frame assembly 100, increase the friction between the rotating wheel 310 and the support frame assembly 100, and realize the self-locking state of the rotating wheel 310.

[0072] like Figure 2 , Figure 3 , Figure 5 or Figure 7 As shown, further, the slide groove 315 has an entrance for inserting the slider, and the side wall of the entrance of the slide groove 315 is formed with a guiding inclined surface.

[0073] With such a configuration, the guiding inclined surface plays a good guiding role in the sliding block sliding into the sliding groove 315 , thereby improving the assembly efficiency of the rotating drum 320 and the rotating wheel 310 .

[0074] like Figure 4 As shown, in some embodiments of the present invention, one of the rotating assembly 300 and the supporting frame assembly 100 is provided with a limit block 321 , and the other one is provided with a second arc-shaped limit groove 122 , and the limit block 321 is disposed in the second arc-shaped limit groove 122 .

[0075] Specifically, the rotating assembly 300 may be provided with a limit block 321, for example, the limit block 321 is provided on the rotating wheel 310 or the limit block 321 is provided on the rotating drum 320; the second arc-shaped limit groove 122 is provided on the support frame assembly 100. Alternatively, the limit block 321 is provided on the support frame assembly 100, and the second arc-shaped limit groove 122 is provided on the rotating assembly 300. By arranging the limit block 321 in the second arc-shaped limit groove 122, the rotating assembly 300 has a certain angle limit when rotating relative to the supporting frame assembly 100, thereby preventing the user from rotating the rotating assembly 300 by an excessive angle.

[0076] The utility model also provides a pair of glasses, which include a frame, temples and a rotating shaft mechanism. The specific structure of the rotating shaft mechanism refers to the above embodiment. Since the glasses adopt all the technical solutions of all the above embodiments, they at least have all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. Among them, the support frame assembly 100 is connected to the frame, and the temples are connected to the rotating assembly 300.

[0077] By connecting the support frame to the frame and the temples to the rotating assembly 300, the temples can rotate relative to the frame, thereby adjusting the opening angle of the temples. In addition, when the rotating shaft mechanism adopts the rotating shaft mechanism of the above embodiment, it can ensure that the temples are in a self-locking state during the rotation process, thereby reducing the risk of the temples automatically falling back.

[0078] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
