As shown in fig. 1-18, the present application provides an attachment mechanism for eyeglasses. The eyeglasses may include a frame and temples that receive lenses. The connection mechanism includes a first member 100, a second member 200, and a third member 300. The first member 100 is adapted to be coupled to a frame. The second member 200 is rotatably connected to the first member 100 by a first rotating shaft 201, and the second member 200 can rotate in a first direction relative to the first member 100. The third member 300 is used to connect with the temples. The third member is rotatably connected to the second member 200 by a second shaft 305, and the third member 300 is capable of rotating relative to the second member 200 in a second direction different from the first direction. Wherein the axial direction of the second rotating shaft 305 is different from the axial direction of the first rotating shaft 201. Through the structure, the opening and closing of the glasses legs in the first direction and the swinging of the glasses legs in the second direction can be realized.

The first direction and the second direction are both arc-shaped rotating directions, and the first direction and the second direction are similar to a cross. The rotation of the second member 200 relative to the first member 100 may be left-right opening and closing (i.e., opening and closing), while the rotation of the third member 300 relative to the second member 200 may be up-down swinging.

When the connecting mechanism of the embodiment of the application is applied to the glasses, the movement of the glasses legs in two different directions can be realized, namely, the two glasses legs of the glasses can be outwards opened (outwards bent), so that the connecting mechanism is suitable for the head circumference of different wearers, and the adaptability is improved. And two mirror legs of glasses can also the luffing motion, realize adjusting from top to bottom to the high of the ear of adaptation different wearers promotes the performance of glasses.

The second rotation shaft 305 may penetrate through the third member 300 and the second member 200, so that the third member 300 is rotatably connected with the second member 200, and the third member 300 can rotate around the second rotation shaft 305. The second shaft 305 may be sleeved with a butterfly spring 306, and the butterfly spring 306 is used for providing rotational damping for the third member 300.

The structure of the coupling mechanism of the present application will be specifically described below with reference to various embodiments.

Example one

The third member 300 has a stopper portion 303, and the stopper portion 303 is configured to act on the first member 100 or the second member 200 of the spindle mechanism when the third member 300 rotates relative to the second member 200, so as to limit the rotation angle of the third member 300.

As shown in fig. 7 and 8, one end of the third member 300 is opposite to the first member 100 with a first gap 308 therebetween, the one end of the third member 300 is used to act on the first member 100 when the third member 300 rotates relative to the second member 200 to limit the rotation angle of the third member 300, and the one end of the third member 300 forms a stopper 303.

As shown in fig. 7 and 8, the upper and lower sides of one end of the first member 100 facing the third member 300 are formed with an upper limit surface 108 and a lower limit surface 109, respectively. The stopper 303 of the third member 300 includes an upper stopper and a lower stopper. The upper limit surface 108 and the upper limit portion of the first member 100 limit the swinging-up angle of the third member 300 (see fig. 7), and the lower limit surface 109 and the lower limit portion of the first member 100 limit the swinging-down angle of the third member 300 (see fig. 8).

Optionally, the first member 100 includes a first member body and a spindle connector coupled to the first member body. The upper and lower sides of the rotation shaft connector facing one end of the third member 300 form an upper and lower limiting surface, respectively, to limit the swing angle of the third member 300.

With continued reference to fig. 1-8, the third member 300 comprises a frame-like structure bounded by two side walls 301 and a bottom wall 302, and the second member 200 is disposed within the frame-like structure. The two side walls 301 and the second member 200 have a second gap 309 therebetween, when the third member 300 rotates relative to the second member 200, the second member 200 can act on the two side walls 301 to limit the rotation angle of the third member 300, and the two side walls 301 form a limiting portion 303. It should be noted that the second gap 309 in the drawings of the present embodiment is larger, which is only an illustration, if the size of the second gap 309 is adjusted, or the

protrusions

311 and 312 are disposed in the second gap 309, when the third member 300 rotates, the second member 200 interferes with the two sidewalls 301 or the

protrusions

311 and 312 of the third member 300, so as to prevent the third member 300 from rotating further. The second member 200 can form a limit to the rotation of the third member 300, thereby limiting the range of rotation of the third member 300.

For example, in the example shown in fig. 1, the bottom wall 302 is provided with protrusions 311 at positions close to the two side walls 301 to define the second member 200 between the two protrusions 311 and to define the rotational displacement of the third member 300 when rotated relative to the second member 200. Or, for example, in the example shown in fig. 2, the two side walls are provided with protrusions 312 extending towards each other to limit the rotational displacement of the third part 300 relative to the second part 200 when the two are rotated.

As shown in fig. 3 to 8, the bottom wall 302 is provided with a first tooth portion 304, the second member 200 is provided with a second tooth portion 217 adapted to the first tooth portion 304, and when the third member 300 rotates relative to the second member 200, the first tooth portion 304 and the second tooth portion 217 elastically contact and relatively move to provide rotational damping. By arranging the first tooth part 304 and the second tooth part 217 which are meshed with each other, the jerking feeling of the rotation process can be increased, and the rotation process can be stopped at the rotated angle.

The second tooth portion 217 includes a plurality of teeth, and adjacent teeth form a tooth space therebetween. First tooth portion 304 may include a plurality of teeth (with adjacent teeth forming a tooth slot therebetween) or may include one tooth. When the connecting member 300 is located at the position shown in fig. 7, the teeth of the first and

second teeth

304 and 217 located lower in the figure are engaged. When the connecting member 300 is located at the position shown in fig. 8, the teeth of the first and

second teeth

304 and 217 located upward in the figure are engaged. That is, as the connecting member 300 rotates relative to the second part 200, different ones of the first and

second tooth portions

304, 217 mesh. First tooth 304 and second tooth 217 may be resilient such that first tooth 304 and second tooth 217 are resiliently deformed when first tooth 304 is moved relative to second tooth 217 to enable first tooth 304 to snap into different tooth slots. The connection member 300 and the second part 200 are maintained in this position without the application of external force.

Optionally, the first teeth 304 on the bottom wall 302 are teeth protruding from the bottom wall 302, and the second teeth 217 of the second member 200 are teeth arranged in a recess of the second member 200, so as to save space.

With reference to fig. 5 and 12, the bottom wall 302 is provided with a protrusion 310 having a central hole and located in the frame-shaped structure, the second member 200 is disposed in the frame-shaped structure, and the protrusion 310 penetrates through the second member 200. The second rotating shaft 305 may be a pin shaft, which is installed in the central hole of the convex pillar 310, and the butterfly-shaped elastic piece 306 is pressed between the convex pillar 310 and the head of the pin shaft. Therefore, the whole pin shaft including the head part is arranged in the frame of the third part 300, the attractiveness of the product can be improved, pins and accessories are protected, and the service life is prolonged.

As shown in fig. 3, 4 and 6, the end of the pin is an elongated cylinder, the holes of the second component 200 corresponding to the end of the pin are elongated holes matched with each other, the center hole of the boss 310 of the third component 300 is a circular hole, that is, the pin and the second component 200 are kept relatively stationary (both are fixed), and the third component 300 can rotate around the pin relative to the second component 200, so as to realize the function of swinging the third component 300 up and down. In addition, the pin shaft may further be sleeved with a friction plate 307, and the friction plate 307 is disposed between the convex column 310 and the butterfly-shaped elastic sheet 306.

The butterfly-shaped elastic piece 306 has elasticity, the initial shape of the butterfly-shaped elastic piece is a curved surface (see fig. 9), when the pin shaft is assembled into the corresponding hole of the second component 200, the butterfly-shaped elastic piece 306 is pressed to be forced to be deformed into a plane (see fig. 10), and the pin shaft and the corresponding hole of the second component 200 can be in interference fit, so that the pin shaft is ensured not to be ejected out due to the resilience force of the butterfly-shaped elastic piece 306. The pin shaft and the second component 200 can also be fixed by riveting or welding and the like, so that the pin shaft can be prevented from being ejected out due to the resilience force of the butterfly-shaped elastic sheet 306, and the butterfly-shaped elastic sheet 306 is always extruded at the moment, so that the damping hand feeling in the rotating process is provided.

The pin shaft is matched with the butterfly-shaped elastic sheet 306 to form a damping shaft. The damping shaft provides stepless damping hand feeling. The cooperation of first tooth 304 and second tooth 217 provides a feel of stepped damping. The damping shaft and the tooth part can be arranged at the same time, only the tooth part without the damping shaft can be arranged, or only the damping shaft without the tooth part can be arranged.

Example two

As shown in fig. 11 to 18, the second embodiment is different from the first embodiment in that the pin is connected to the second member 200 after passing through the third member 300 from the outer side of the third member 300. The pin in the first embodiment is inserted through the second member 200 and the third member 300 from the inner side of the third member 300. The structure of the other parts of the second embodiment is basically the same as that of the first embodiment, and the description thereof is omitted.

As shown in fig. 19 to 41, the first member and the second member are assembled together by the first rotating shaft 201 to form a rotating shaft mechanism. Specifically, the rotating shaft mechanism comprises a first rotating shaft 201, a first component 100, a second component 200 and a matching part 102; the first component 100 has a first abutment 101. The second component 200 has a second abutment 202; the second member 200 is rotatably coupled to the first member 100 by a first rotating shaft 201, the second member 200 is rotatable within a predetermined angle range with respect to the first member 100, and the second member 200 has a first position and a second position. Optionally, either the first component 100 or the second component 200 includes a mating portion 102. When the engaging portion 102 is formed on the first component 100, the engaging portion 102 is engaged with the first abutting portion 101 and forms a first included angle α therebetween. When the mating portion 102 is formed on the second component 200, the mating portion 102 is engaged with the second abutting portion 202 to form a second included angle β therebetween. Optionally, the first included angle α and the second included angle β define a rotation angle range of the second member 200 with respect to the first member 100. That is, when the fitting portion 102 is formed at the first member 100, the predetermined angle ranges from 0 to 180 ° - α; when the fitting portion 102 is formed on the second member 200, the predetermined angle is in the range of 0 to 180 ° - β. The values of alpha and beta can be determined according to the actual application field and product of the rotating shaft mechanism and the actual rotating angle required. Further, α and β may be equal or different.

For example, the engaging portion 102 is engaged with the first abutting portion 101 (or the second abutting portion 202), and the engaging portion 102 and the first abutting portion 101 (or the second abutting portion 202) may be disposed on the same component, and two portions may extend continuously, or disposed on different components, and two portions may extend continuously. It is understood that there may also be a space between the mating portion 102 and the first abutment 101 (or, the second abutment 202).

For example, the rotating shaft mechanism may be applied to glasses, a temple 405 of the glasses is connected to the second component 200, a frame 404 of the glasses is connected to the first component 100, and the second component 200 can drive the temple 405 to rotate relative to the first component 100 and the frame 404, so as to realize the outward extension of the temple 405, so that the glasses can be suitable for different wearers' head circumferences and are convenient to wear. For example, when the temples 405 are required to be outwardly expanded by 10 ° to 15 °, the first and second included angles may be set to 165 ° to 170 °, respectively.

When the mating portion 102 is formed on the first component 100 and the second component 200 is located at the first position, the first abutting portion 101 and the second abutting portion 202 interact with each other to hold the second component 200 at the first position. When the mating portion 102 is formed on the first component 100 and the second component 200 is in the second position, the mating portion 102 interacts with the second abutment 202 to retain the second component 200 in the second position. When the engaging portion 102 is formed on the second member 200 and the second member 200 is located at the first position, the first abutting portion 101 and the second abutting portion 202 interact with each other to hold the second member 200 at the first position. When the engaging portion 102 is formed on the second member 200 and the second member 200 is located at the second position, the first abutting portion 101 and the engaging portion 102 interact with each other to hold the second member 200 at the second position.

In the spindle mechanism according to the embodiment of the present application, the engaging portions are provided on the first member 100 and the second member 200, and the abutting portions are provided on the first member 100 and the second member 200, respectively, so that the second member 200 can rotate relative to the first member 100, and the engaging portions and the abutting portions act in a switching manner during rotation, so that the second member 200 can be held at the first position or the second position after rotation, and the angle between the first member 100 and the second member 200 can be adjusted.

Alternatively, a ramp may be provided on the first and

second members

100, 200 and a flat surface may be provided on the first and

second members

100, 200 respectively, such that the second member 200 is able to rotate relative to the first member 100 and switch between ramp to flat (e.g. ramp to flat) and flat to flat (e.g. flat to flat) action upon rotation. It will be appreciated that both the terms "flat" and "beveled" described above may have a substantially flat surface, the term "beveled" being so named because it is at an angle relative to the term "flat". Alternatively, the engaging portion may have a curved surface, a concave portion, a projection, or the like, and the abutting portion may have a curved surface, a concave portion, a projection, or the like.

Alternatively, the first abutting portion, the second abutting portion, and the fitting portion may be provided at a portion between the first member and the second member, and shielded by the first member and/or the second member so as to be not easily visible from the outside.

In some embodiments, the hinge mechanism may further include an elastic member disposed between the first member 100 and the second member 200 for providing a restoring force to the second member 200 to rotate from the second position toward the first position, so that the second member 200 can be restored from the second position to the first position when no external force is applied.

The specific structure, the setting position and the action mode of the elastic member are not particularly limited in this application, as long as the second member 200 can be reset by the rotation of the second position toward the first position. In one example, the elastic member may be an elastic body, and the elastic body may be deformable in a direction perpendicular to the axial direction of the first rotating shaft 201 to provide the second component 200 with a restoring force rotating from the second position toward the first position, for example, in a direction substantially perpendicular to the axial direction of the first rotating shaft 201.

For example, in embodiments where the hinge mechanism described above is applied to eyeglasses, when no external force is applied to the eyeglasses, the second member 200 is in the first position and the temple 405 of the eyeglasses can be understood to be in an un-extended state. To ensure that the temple 405 is stably held in the first position, the elastic member may be given a certain deformation to apply a certain force to the second part 200. When an external force is applied to the glasses to outwardly spread the temples 405, the relative distance between the temples 405 is increased to fit the head circumference of different users. As the temple 405 is extended, the second part 200 rotates relative to the first part 100 about the first rotation axis 201, and the second part 200 continues to deform the elastic member until the second part 200 rotates to the second position. Since the engagement portion 102 interacts with the first abutment 101 or the second abutment 202, the second part 200 is restrained from further rotation in the second position, the amount of deformation of the elastic member is maximized and the temple 405 is thereby outwardly extended to a maximum extent. After the second member 200 leaves the first position, whether in a position between the first position and the second position or in the second position, the elastic member can apply a force to the second member 200 under the deformation, so that the second member 200 can be restored from the second position to the first position when no external force is applied.

Although the above describes the change of the elastic member during the rotation of the second member 200 by taking the eyeglasses as an example, it is understood that the rotation shaft mechanism can be similarly understood when it is used in other devices.

The following describes a specific structure of the spindle mechanism according to the present application in various embodiments. For convenience of description, the rotation of the second member 200 from the first position to the second position is referred to as outward expansion, and the rotation of the second member 200 from the second position to the first position is referred to as return. In addition, "upper", "lower", "left" and "right" are for positions in the drawings.

Example one

As shown in fig. 19 to 21, the engaging portion 102 in the first embodiment is formed on the first component 100, one end of the elastic body abuts against a portion of the second component 200, which is used for interacting with the first abutting portion 101 of the first component 100, and the other end abuts against a portion of the first component 100, which is opposite to the first abutting portion 101; the first rotating shaft 201 is close to the matching part 102 relative to the elastic body.

With continued reference to fig. 19-21, the resilient body includes a compression spring 210, the compression spring 210 being retractable in a direction substantially perpendicular to the axial direction of the first axis of rotation 201. The second component 200 includes a pivot portion 203, the second abutting portion 202 is located on a first side of the pivot portion 203, a spring seat 204 is disposed on a portion, corresponding to the first abutting portion 101 of the first component 100, of a second side of the pivot portion 203, one end of a compression spring 210 is located on the spring seat 204, a portion, corresponding to the mating portion 102 of the first component 100, of the second side of the pivot portion 203 includes a shaft seat 205, and the first rotating shaft 201 penetrates through the shaft seat 205.

For example, the outer, front and inner side walls of the first component 100 in fig. 20 and 21 define a pocket, with the upper portion of the left side wall 301 (i.e., the outer side wall) of the pocket forming the first abutment 101 and the lower portion of the left side wall 301 being inclined outwardly to form the mating portion 102. In this example, the first abutment 101 may be planar, and the mating portion 102 may be beveled, as opposed to planar. The upper portion of the second member 200 forms a pivot portion 203, the left side (the side close to the left side wall 301, which may also be understood as the side facing the left side wall 301) of the pivot portion 203 is the first side, and forms a second abutment portion 202, and the second abutment portion 202 corresponds to both the first abutment portion 101 and the engagement portion 102. In this example, the second abutment 202 may be planar. The second side of the pivot portion 203, which is facing away from the first abutment 101, may be referred to as the right side. The upper right side of the pivot portion 203 is recessed to form a recess in which the spring seat 204 is provided. The spring seat 204 in this embodiment may be a convex pillar, and one end of the compression spring 210 may be sleeved on the convex pillar. The right lower part (the part far from the front side wall) of the pivoting part 203 forms a convex part relative to the upper part, the convex part is used as a shaft seat 205 of the first rotating shaft 201, and the first rotating shaft 201 penetrates through the shaft seat 205. Thereby, the first rotating shaft 201 is close to the matching part 102 relative to the compression spring 210 (elastic body), which facilitates the compression spring 210 to apply force, and provides the second component 200 with a reset force rotating from the second position to the first position.

The compression springs 210 may be provided in plurality, e.g., two, arranged in parallel to provide a stable and uniform return force to the second member 200.

As shown in fig. 20, when the second member 200 is at the first position, the compression spring 210 applies an urging force to the second member 200 so as to abut against the first member 100, and the second abutting portion 202 of the second member 200 abuts against the first abutting portion 101 of the first member 100 and can be held at the first position. When a force is applied to the second member 200 to cause it to expand outwardly to the left in the drawing, the second member 200 rotates until its second abutment portion 202 abuts against the engagement portion 102 on the first member 100, see fig. 21, with the compression spring 210 still in a compressed state and applies a force to the second member 200 tending to return from the second position to the first position.

Example two

As shown in fig. 22 to 30, the fitting portion 102 is formed at the second member 200. The elastic members include elastic columns respectively located at opposite sides of the first rotating shaft 201, and the elastic columns respectively pass through the second member 200. When the second member 200 is switched from the first position to the second position, the elastic columns located on different sides of the first rotating shaft 201 are elastically deformed in opposite directions. The second member 200 is provided with a restoring force by elastically deforming the elastic columns in the opposite direction to rotate from the second position toward the first position.

For example, as shown in fig. 24 and 25, the second member 200 includes a first protrusion 206 on a first side thereof and a second protrusion 207 on a second side thereof. The elastic column includes a first elastic column 211 and a second elastic column 212, the first elastic column 211 passes through the first protrusion 206 and has two ends fixed to the first member 100, and the second elastic column 212 passes through the second protrusion 207 and has two ends fixed to the first member 100.

With continued reference to fig. 24 and 25, the first component 100 includes a first ear plate 103 and a second ear plate 104 disposed in an opposing relationship. The first rotating shaft 201 passes through the second member 200, and both ends are connected to the two ear plates, respectively. Two ends of the two elastic columns are respectively fixed with the two ear plates.

As shown in fig. 22, the first member 100 further includes an end plate 105, and both of the lug plates are provided on a plate surface (surface) of the end plate 105, the plate surface forming the first abutting portion 101. One end of the second member 200 faces the plate surface, and forms a second abutting portion 202. The first rotation axis 201 is parallel to the first abutment 101 and the second abutment 202. The first and second

resilient columns

211, 212 are both parallel to the first axis of rotation 201 in an undeformed state (when the second member 200 is in the first position).

As shown in fig. 26 to 28, when the second member 200 rotates from the first position shown in fig. 26 and 27 to the second position shown in fig. 28, that is, the second member 200 rotates to the left (outward) side shown in fig. 26 and 28, the first protrusion 206 and the second protrusion 207 of the second member 200 respectively drive the elastic columns penetrating through the elastic columns to elastically deform. The first convex portion 206 on the left side (outer side) in fig. 26 and 28 brings the first elastic column 211 on the left side to elastically deform toward the upper portion shown in the drawing (when the hinge mechanism is applied to the smart glasses, the first elastic column 211 comes close to the front frame of the glasses). The second protrusion 207 located on the right side (inner side) in fig. 26 and 28 brings the second elastic column 212 located on the right side to elastically deform toward the lower portion shown in the drawing (when the hinge mechanism is applied to the smart glasses, the first elastic column 211 moves away from the front frame). The elastic column has the characteristic of restoring deformation after being deformed so as to realize the resilience force when the second component 200 is outwards expanded.

EXAMPLE III

As shown in fig. 31 to 33, the fitting portion 102 is formed in the second member 200. The first and

second members

100 and 200 define a receptacle 106. The elastic member is an elastic cushion block 213, and the elastic cushion block 213 is disposed in the accommodating portion 106 and abuts against the first member 100 and the second member 200. When the second member 200 rotates from the first position to the second position, i.e. expands to the second position to the left in the drawing, the second member 200 presses the elastic pad 213 to deform it elastically (see fig. 33), and accumulates elastic potential energy, thereby obtaining a resilient force to provide the second member 200 with a restoring force rotating from the second position to the first position. That is, the force for returning the second member 200 from the second position to the first position can be obtained by the resilient force of the resilient pad 213.

With continued reference to fig. 31, the first member 100 has a cavity into which one end of the second member 200 extends and forms a receptacle 106 with a left sidewall 301 (outer sidewall) of the cavity. The end face of the second part 200 that projects into one end of the cavity forms a second abutment 202. The surface of the first component 100 opposite the second abutment 202 forms the first abutment 101 and the mating portion 102. That is, the cavity bottom of the cavity forms the first abutment 101 and the mating portion 102. A first side surface of the resilient pad 213 is attached to a side surface of the second member 200 located in the receiving portion 106, and a second side surface of the resilient pad 213 is attached to a side wall 301 surface of the receiving cavity opposite to the side surface of the second member 200. To fix the resilient pad 213, the resilient pad 213 may be adhered to the side wall 301 of the receiving chamber.

Example four

As shown in fig. 34 to 36, the difference between the fourth embodiment and the third embodiment is only that the elastic pad 213 is replaced with an elastic piece 214. The elastic piece 214 is disposed in the accommodating portion 106, and when the second member 200 is located at the second position, the elastic piece 214 deforms to provide a restoring force for the second member 200 to rotate from the second position to the first position.

In the fourth embodiment, the outward-extending resilience of the second member 200 can be realized by the elastic sheet 214. The elastic sheet 214 can be fixed on the side wall 301 of the accommodating part 106 of the first member 100 by means of adhesion or welding, and the elastic sheet 214 is compressed when the second member 200 rotates outwards to obtain resilience.

EXAMPLE five

As shown in fig. 37 to 39, the elastic member includes a clip group 215 formed by stacking a plurality of clips in sequence; the group of spring plates 215 acts on the end face of the second member 200 adjacent to the second abutment 202. When the second member 200 is located at the second position, the resilient member 215 deforms to provide a restoring force to the second member 200, which is rotated from the second position to the first position.

With continued reference to fig. 37 to 39, the first member 100 has a cavity, an upper portion of a left sidewall 301 of the cavity forms the first abutting portion 101, and a lower portion of the left sidewall 301 of the cavity forms the mating portion 102 inclined to the outside. The first end of the second member 200 extends into the cavity, and the resilient tab set 215 is located between the first end of the second member 200 and the upper sidewall 301 of the cavity. A plurality of shell fragments stack from top to bottom in proper order. One side of the first end of the second component 200 close to the left side wall 301 of the cavity protrudes from one side of the left side wall 301 far away from the cavity to form a protrusion, and the elastic sheet group 215 acts on the end face of the protrusion. The first hinge 201 is located below the projection and as far away from the left sidewall 301 of the cavity as possible so that the spring pack 215 provides a force to the second part 200 to return it from the second position to the first position. In order to leave a space for deformation of the spring plate set 215, the top side wall of the housing defines a recess to deform the free end (end surface acting on the protrusion) of the spring plate set 215, and the top side wall of the housing is further provided with a mounting portion to fix the fixed end of the spring plate set.

The first member 100 in the above embodiments may include a first member body and a hinge connector. The shaft connector and the first member body may be a single piece. Alternatively, the shaft connector is connected to the first member body. The first abutting portion 101 is formed on a rotation shaft connector, and the second member 200 is rotatably connected to the rotation shaft connector through a first rotation shaft 201.

All of the elastic members in the above embodiments can provide a pre-tightening force, so that the second member 200 is not easily rotated. It should be noted that, if the elastic column in the second embodiment is to provide the pre-tightening force, the upper, middle and lower three points of the elastic column are not collinear, that is, the holes for fixing the elastic column by the first ear plate 103 and the second ear plate 104 and the protrusions for passing through the holes of the elastic column are not coaxial, so as to provide the pre-tightening force in advance.

As shown in fig. 40 to 59, the present embodiment also provides a pair of glasses 400. The glasses 400 comprise a frame 404 and a temple 405, and the glasses 400 further comprise a rotating shaft mechanism of any one of the above embodiments; or the eyeglasses 400 further comprise any of the above-described embodiments of attachment mechanisms 420 for eyeglasses. The frame 404 and temple 405 are connected by a hinge mechanism or connection mechanism 420.

When the eyeglasses 400 comprise two sets of pivot mechanisms, the first members 100 of the two sets of pivot mechanisms are respectively fixed to the frame 404, and the two legs 405 are respectively hinged to the second members 200 of the two sets of pivot mechanisms. Since the second member 200 can rotate left and right with respect to the first member 100, the two temples 405 connected to the second member 200 can be outwardly bent, so that the distance between the two temples 405 can be adjusted to suit the head circumference of different wearers. In addition, the temple 405 is hinged to the second member 200 so that the temple 405 can be folded for convenient storage.

When the eyeglasses 400 comprise two sets of connecting mechanisms 420, the first members 100 of the two sets of connecting mechanisms 420 are respectively fixed to the frame 404, and the two legs 405 are respectively hinged to the third members 300 of the two sets of connecting mechanisms 420. Since the second member 200 can rotate left and right with respect to the first member 100, the two temples 405 can be outwardly bent, so that the distance between the two temples 405 can be adjusted to suit the head circumference of different wearers. Since the third part 300 can be rotated up and down relative to the second part 200, the two temples 405 can be adjusted up and down to accommodate the height of the ears of different wearers. In addition, the temple 405 is hinged to the third member 300 so that the temple 405 can be folded for convenient storage. The glasses 400 of the embodiment of the application have the advantages of strong applicability, convenience in wearing and good use experience of a user.

As shown in fig. 41, the frame 404 of the eyeglasses 400 and the first member 100 may be separate structures. The frame 404 may be provided with a fixing hole 406, and the first member 100 may be fixed to the frame 404 by a connecting member such as a screw 407. Of course, the frame 404 may be directly formed as the first member 100; or the frame 404 as part of the first member 100; or the frame 404 may be integral with the first member 100. The frame 404 may be made of plastic material, such as ABS/PC. In order to ensure wear and fatigue resistance during rotation, the first component 100 may be made of aluminum alloy, stainless steel or polyoxymethylene POM. When the frame 404 and the first member 100 are a unitary piece, both may be of a metallic material and may be directly integrally molded for ease of assembly.

As shown in fig. 40, the glasses 400 are smart glasses, which further include an optical imaging system 401. As shown in fig. 60, the optical imaging system 401 includes an image source assembly 402 and an optical assembly 403. The smart glasses may be head-mounted display devices such as AR glasses, VR glasses, and the like. The image source module 402 is used to display an image projected into the human eye, and the optical module 403 functions to change the optical path.

The connection of the mirror legs 405 to the third member 300 and the routing of the data lines 408 will be described with reference to different embodiments.

Example one

When the eyeglasses 400 are smart eyeglasses, the frame 404 (display body) and the temple 405 of the smart eyeglasses are typically connected by a data cable 408. As shown in fig. 42 and 43, the data line 408 extends from the display body, through the third component 300, and to the temple 405. As shown in fig. 43, 45 and 46, eyewear 400 further includes a folding hinge 409 and a hinge mount 410. The hinge fixing base 410 is fixed on the inner side of the temple 405, and for the convenience of disassembly, the hinge fixing base 410 can be clamped on the temple 405 and fixed through a buckle. One end of the folding hinge 409 is rotatably connected to the third member 300 and the other end is fixed to the hinge holder 410 so that the temple 405 can rotate with respect to the third member 300. The temple arm 405 is hinged with the third member 300 by a folding hinge 409, the temple arm 405 can be folded and unfolded, and the temple arm 405 is folded for easy storage and carrying.

With continued reference to fig. 46, the folding hinge 409 includes a hinge portion 411 and a third rotating shaft 412, and the hinge portion 411 has a through hole 413 and a slit 414 (see fig. 49) penetrating both axial ends thereof and communicating with the through hole 413. The third shaft 412 penetrates through the through hole 413 and is tightly matched with the through hole 413 so as to provide rotation damping for the folding hinge 409.

With continued reference to fig. 45 and 46, the portion of the data cable 408 extending into the temple 405 may be secured within the temple 405 by a hinge mount 410. That is, the data cable 408 is positioned between the temple 405 and the hinge holder 410. The hinge fixing base 410 in the first embodiment may be two hinge fixing bases arranged in parallel. The folding hinge 409 is assembled and fixed with the two hinge fixing seats 410 through two screws respectively, so that the folding hinge 409 is prevented from being twisted, and the stability is improved.

As shown in fig. 47 and 48, the eyeglasses 400 further include a connector cover 415 and a temple cover 416, the connector cover 415 being attached to the third member 300 for covering the data line 408 passing through the third member 300. A temple cover 416 is positioned over the temple 405 to enclose the data cable 408 within the temple 405. The cover plate may be attached to the third member 300 or the temple 405 using glue or by snap-fitting. The opposite ends of connector cover 415 and temple cover 416 are flexibly connected to allow relative rotation and folding of the temples 405, and the connection cover and temple cover 416 are bent at their connection so as not to interfere with folding of the temples 405. A flexible connection is a connection that is relatively rigid, in that it is capable of rotating at the connection. For example by means of an elastically or flexibly deformable component, such as a connection by means of silicone, rubber, flexible tape or the like. Of course, the rotational connection between connector cover 415 and temple cover 416 may also be made to facilitate rotation as the temple 405 is bent without affecting the bending of the temple 405. Of course, connector cover 415 and temple cover 416 may also be a clearance fit, such that when temple 405 is switched between folded and unfolded, the ends of connector cover 415 and temple cover 416 that are opposite each other do not interfere, and thus do not interfere with the unfolding and folding of temple 405. The unfolded state and the folded state of the temples 405 can be seen in fig. 49 and 50.

Example two

As shown in fig. 51 and 52, the third part 300 of the temple 405 is rotatably connected by the cooperation of the pin 417 and the snap spring 418. For example, with continued reference to fig. 51, the third member 300 and the temple 405 are frame-shaped structures with opposite ends adapted to each other, the end of the temple 405 is wrapped around the end of the third member 300, and the upper sidewall 301 of the temple 405 and the upper sidewall 301 of the third member 300 are respectively provided with corresponding upper assembling holes. The lower side wall 301 of the temple 405 and the lower side wall 301 of the third member 300 are opened with corresponding lower fitting holes, respectively. The number of the pins 417 may be two, and the two pins 417 are respectively installed in the upper and lower installation holes. The portion of the pin 417 that extends out of the mounting hole is provided with a snap spring 418 to retain the pin 417 within the mounting hole.

The pin 417 may be a close fit with the mounting hole to provide rotational damping, see fig. 54. Alternatively, a washer 419 may be provided between the pin 417 and the mounting hole, i.e., the portion of the pin 417 within the mounting hole is sleeved over the washer 419 to provide rotational damping, see fig. 55. Of course, the pin 417 may be replaced by other shaft-like members, and is not limited to the pin 417.

As shown in fig. 53, when the temple 405 and the third member 300 are hinged, the data cable 408 extends from the frame 404 through the third member 300 to the temple 405. As shown in fig. 56 and 57, eyewear 400 further includes connector cover 415 and temple cover 416, which are capable of positioning data line 408 within third component 300 and temple 405. The connection, engagement, etc. of the connector cover 415 and the temple cover 416 may be the same as in the first embodiment, and will not be described herein.

As shown in fig. 58 and 59, the temple 405 can be unfolded and folded with respect to the third member 300, and is folded for storage and carrying.

The glasses 400 of the embodiment of the application can be expanded, can swing up and down, can be folded, and improves the use experience of the user wearing the glasses 400. The outward-expanding rebound function is realized through the elastic columns, the compression springs 210, the elastic cushion blocks 213, the elastic sheets, the elastic sheet set 215 and the like, and the butterfly-shaped elastic sheet 306 provides swing damping, so that the wearing is more comfortable. Through reasonable structural arrangement, the data line 408 penetrates through the inside, and the whole structure is sealed.

The above description is intended to be illustrative, and not restrictive, and variations, modifications, substitutions, and alterations may be made to the above-described embodiments by those of ordinary skill in the art within the scope of the present disclosure. Also, the above-described examples (or one or more versions thereof) may be used in combination with each other, and it is contemplated that the embodiments may be combined with each other in various combinations or permutations.
