In order to keep the following description of the embodiments of the present application clear and concise, the detailed description of known functions and known components thereof have been omitted.

As shown in fig. 1 to 18, an embodiment of the present application provides a connection mechanism for eyeglasses. The eyeglass can include a frame and a temple that receive a lens. The connection mechanism includes a first part 100, a second part 200 and a third part 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 shaft 201, the second member 200 being rotatable relative to the first member 100 in a first direction. The third member 300 is for connection with a temple. The third member is rotatably connected to the second member 200 by a second rotation shaft 305, and the third member 300 is rotatable relative to the second member 200 in a second direction different from the first direction. Wherein the axial direction of the second rotation shaft 305 is different from the axial direction of the first rotation shaft 201. With the above structure, the folding and unfolding of the temple in the first direction and the swinging of the temple in the second direction can be realized.

The first direction and the second direction are arc-shaped rotation directions, and the first direction and the second direction are similar to cross. The rotation of the second member 200 relative to the first member 100 may be side-to-side opening and closing (i.e., expanding and closing), while the rotation of the third member 300 relative to the second member 200 may be an up-and-down swing.

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 stretched (outwards broken) so as to adapt to the head circumferences of different wearers and improve the adaptability. And two mirror legs of glasses can also swing from top to bottom, realize adjusting from top to bottom to adapt to the height of different wearers' ears, promote the performance of glasses.

Alternatively, in addition to the rotation of the third member 300 with the second member 200 by using the second rotation shaft 305 as a rotation shaft, a protrusion 310 (which will be described in detail below) on the third member 300 may be used as a rotation shaft, and the protrusion 310 may be connected with the third member 300 and pass through the second member 200. For example, the second member 200 is sleeved on the boss 310 and can rotate around the boss 310. In one example, the post 310 may be a unitary piece extending from the third member 300.

Alternatively, referring to fig. 11-12, the second shaft 305 may be threaded through the third member 300 and the second member 200 such that the third member 300 is rotatably coupled to the second member 200 and the third member 300 is rotatable about the second shaft 305.

Optionally, a butterfly spring piece 306 may be sleeved on the second rotating shaft 305, where the butterfly spring piece 306 is used to provide rotational damping for the third component 300.

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

Example 1

The third member 300 has a limiting portion 303, and the limiting portion 303 is configured to act with 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, and one end of the third member 300 is adapted to interact with the first member 100 when the third member 300 is rotated relative to the second member 200 to limit the rotation angle of the third member 300, and one end of the third member 300 forms a limiting portion 303.

As shown in fig. 7 and 8, upper and lower sides of one end of the first member 100 toward the third member 300 form upper and lower stopper surfaces 108 and 109, respectively. The limiting portion 303 on the third member 300 includes an upper limiting portion and a lower limiting portion. The upper limit surface 108 and the upper limit portion of the first member 100 limit the angle of the upper swing 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 angle of the lower swing of the third member 300 (see fig. 8).

Alternatively, the first member 100 includes a first member body and a rotation shaft coupling coupled to the first member body. The upper and lower sides of the end of the rotation shaft connection member facing the third member 300 form an upper limit surface and a lower limit surface, respectively, to limit the swing angle of the third member 300.

With continued reference to fig. 1-8, the third component 300 includes a frame-shaped structure surrounded by two side walls 301 and a bottom wall 302, and the second component 200 is disposed within the frame-shaped structure. The second gap 309 is formed between the two side walls 301 and the second member 200, and 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 the limiting portion 303. It should be noted that, in the illustration of this embodiment, the second gap 309 is larger, which is merely an illustration, and if the size of the second gap 309 is adjusted, or the protrusions 311 and 312 are provided in the second gap 309, when the third member 300 rotates, the second member 200 may interfere with both side walls 301 or the protrusions 311 and 312 of the third member 300, thereby preventing the third member 300 from rotating continuously. 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 near both side walls 301 to define the second member 200 between the two protrusions 311, and rotational displacement of the third member 300 with respect to the second member 200 is defined therebetween. Or for example in the example shown in fig. 2, the two side walls are provided with protrusions 312 extending towards each other to define rotational displacement of the third part 300 when it is rotated relative to the second part 200.

As shown in fig. 3 to 8, the bottom wall 302 is provided with a first tooth 304, the second member 200 is provided with a second tooth 217 adapted to the first tooth 304, and when the third member 300 rotates relative to the second member 200, the first tooth 304 and the second tooth 217 elastically contact and move relative to each other to provide rotational damping. By providing the first tooth 304 and the second tooth 217 which are engaged with each other, the feel of the rotation process can be enhanced, and the rotation can be stopped at a post-rotation angle.

The second tooth portion 217 includes a plurality of teeth, and tooth slots are formed between adjacent teeth. The first tooth 304 may include a plurality of teeth (tooth slots are formed between adjacent teeth) or may include one tooth. When the connecting member 300 (third component) is located at the position shown in fig. 7, the teeth of the first tooth portion 304 and the second tooth portion 217 located at the lower side in the drawing are engaged. When the connecting member 300 (third component) is located at the position shown in fig. 8, the teeth of the first tooth portion 304 and the second tooth portion 217 located above in the drawing are engaged. That is, as the connecting member 300 (third component) rotates relative to the second component 200, different ones of the first teeth 304 and the second teeth 217 mesh.

Alternatively, in one example, the first and second teeth 304, 217 may have elasticity such that when the first teeth 304 move relative to the second teeth 217, the first and second teeth 304, 217 elastically deform such that the first teeth 304 can snap into different tooth slots. The connection member 300 (third component) and the second component 200 remain in this position without the action of external force.

Optionally, the first tooth 304 on the bottom wall 302 is a tooth protruding from the bottom wall 302, and the second tooth 217 of the second component 200 is a tooth arranged in a recess of the second component 200, so that space can be saved.

With continued reference to fig. 5, the bottom wall 302 is provided with a boss 310 located in the frame structure, and the second component 200 is disposed in the frame structure, with the boss 310 penetrating the second component 200. In this embodiment, the boss 310 may form a rotation shaft instead of the second rotation shaft 305. The boss 310 is fixed with respect to the third member 300. The second member 200 is sleeved on the boss 310 and can rotate around the boss 310, so that the third member 300 is rotatably connected to the second member 200 through the boss 310. The post 310 may have a central hole, and the pin 305 is mounted to the central hole of the post 310. The butterfly spring 306 is pressed between the boss 310 (the second rotating shaft) and the head of the pin 305. In this way, the whole body of the pin shaft 305 including the head can be located in the frame of the third component 300, so that the aesthetic property of the product can be improved, the pins and accessories can be protected, and the service life can be prolonged.

As shown in fig. 3, 4 and 6, the end of the boss 310 is in a long cylindrical shape, the hole on the second component 200 corresponding to the end of the boss 310 is a round hole, and the central hole on the boss 310 of the third component 300 is a round hole, that is, the shaft pin 305 and the second component 200 are kept relatively stationary (fixed with each other), and the second component 200 can rotate around the boss 310 relative to the third component 300, so as to realize the function of swinging the third component 300 up and down. In addition, a friction plate 307 may be sleeved on the boss 310 (the second rotating shaft), and the friction plate 307 is disposed between the boss 310 and the butterfly spring 306.

The butterfly spring 306 has a curved surface (see fig. 9) with an elastic initial shape, and when the pin 305 is assembled into the corresponding hole of the second component 200, the butterfly spring 306 is extruded to force the butterfly spring to deform into a plane (see fig. 10), and the pin 305 and the corresponding hole of the second component 200 can be in interference fit, so that the pin 305 is ensured not to be ejected out due to the resilience force of the butterfly spring 306. The pin 305 and the second component 200 may also be fixed by riveting or welding, so as to ensure that the pin is not ejected out due to the resilience force of the butterfly spring 306, and at this time, the butterfly spring 306 is always extruded to provide damping feel in the rotation process.

Optionally, in one example, the third member 300 and the second member 200 are also moved relative to each other upon relative rotation of the first tooth 304 and the second tooth 217. The second member 200 is forced to move slightly outwardly (away from the bottom wall 302) in the axial direction of the post 310 when the highest points of the two teeth are in contact, and the second member 200 moves slightly inwardly (toward the bottom wall 302) in the axial direction of the post 310 when the lowest points of the two teeth are in contact. Because the second component 200 is sleeved with the butterfly spring piece 306, when the third component 300 rotates relative to the second component 200, the first tooth portion 304 and the second tooth portion 217 can elastically contact under the deformation action of the butterfly spring piece 306.

The pin shaft 305 is matched with the butterfly spring piece 306 to form a damping shaft. The damping shaft provides stepless damping hand feeling. The cooperation of the first tooth 304 and the second tooth 217 provides a stepped damping feel. The damping shaft and the tooth portion may be provided at the same time, or only the tooth portion may be provided without the damping shaft, or only the damping shaft may be provided without the tooth portion.

Example two

As shown in fig. 11 to 18, the second embodiment is different from the first embodiment in that the second rotation shaft (pin 305) is connected to the second member 200 after passing through the third member 300 from the outside of the third member 300. The second rotation shaft (the boss 310) in the first embodiment is passed through the second member 200 and the third member 300 from the inner side of the third member 300. The other parts of the second embodiment are basically the same as those of the first embodiment, and will not be described here again.

The end of the pin 305 is long cylindrical, the hole corresponding to the end of the pin on the second component 200 is a long round hole matched with each other, the central hole on the boss 310 of the third component 300 is a round hole, that is, the pin 305 and the second component 200 are kept relatively stationary (fixed), and the third component 300 can rotate around the pin 305 relative to the second component 200, so as to realize the up-and-down swinging function of the third component 300. In addition, a friction plate 307 can be sleeved on the pin shaft 305, and the friction plate 307 is arranged between the pin shaft 305 and the butterfly-shaped elastic sheet 306.

In this embodiment, the pin 305 may be a second shaft 305, and the pin 305 may penetrate through the third member 300 and the second member 200 and be fixed to the second member 200, so that the third member 300 forms a rotational connection with the second member 200 around the pin 305, and the third member 300 can rotate around the second shaft 305 relative to the second member 200.

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

For example, the engaging portion 102 may be engaged with the first abutting portion 101 (or the second abutting portion 202), the engaging portion 102 may be provided on the same member as the first abutting portion 101 (or the second abutting portion 202), two portions may be continuously extended, or two portions may be provided on different members, and two portions may be continuously extended. It is understood that the mating portion 102 and the first abutting portion 101 (or the second abutting portion 202) may have a space therebetween.

For example, the rotation shaft mechanism may be applied to glasses, the glasses legs 405 of the glasses are connected with the second component 200, the frame 404 of the glasses is connected with the first component 100, the second component 200 can drive the glasses legs 405 to rotate relative to the first component 100 and the frame 404, and the outer stretching of the glasses legs 405 is achieved, so that the glasses can be suitable for the head circumference of different wearers, and the wearing is convenient. For example, when the temple 405 needs to be expanded by 10 ° to 15 °, the first included angle and the second included angle may be set to 165 ° to 170 °, respectively.

When the engaging portion 102 is formed on the first member 100 and the second member 200 is located at the first position, the first abutting portion 101 and the second abutting portion 202 act to hold the second member 200 at the first position. When the engaging portion 102 is formed on the first member 100 and the second member 200 is located at the second position, the engaging portion 102 acts with the second abutting portion 202 to hold the second member 200 at 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 act to hold the second member 200 at the first position. When the fitting 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 acts with the fitting portion 102 to hold the second member 200 at the second position.

In the rotating shaft mechanism of the embodiment of the application, the matching parts are arranged on the first component 100 and the second component 200, and the abutting parts are respectively arranged on the first component 100 and the second component 200, so that the second component 200 can rotate relative to the first component 100, and the matching parts and the abutting parts act and the abutting parts act are switched during rotation, so that the second component 200 can be kept at the first position or the second position after rotation, and the angle adjustment between the first component 100 and the second component 200 is realized.

Alternatively, a bevel may be provided on the first and second members 100, 200 and a flat may be provided on the first and second members 100, 200, respectively, such that the second member 200 is rotatable relative to the first member 100 and switches between bevel-to-flat action (e.g., bevel-to-flat abutment) and flat-to-flat action (e.g., flat-to-flat abutment) upon rotation. It will be appreciated that both the terms "planar" and "beveled" described above may have a substantially planar surface, the "beveled" being named as being angled with respect to the term "planar". Alternatively, the mating portion may have a curved surface, a concave portion, a convex portion, or the like, and the abutting portion may have a curved surface, a concave portion, a convex portion, or the like.

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

In some embodiments, the spindle 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 that rotates 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 in the absence of an external force.

The specific structure, arrangement position and mode of action of the elastic member are not particularly limited in the present application, as long as the restoring force that rotates from the second position toward the first position can be provided to the second member 200. In one example, the resilient member may be an elastomer that is deformable in a direction perpendicular to the axial direction of the first shaft 201 to provide the second member 200 with a restoring force that rotates from the second position toward the first position, such as in a direction substantially perpendicular to the axial direction of the first shaft 201.

For example, in embodiments in which the hinge mechanism described above is used with eyeglasses, the second portion 200 is in the first position when no external force is applied to the eyeglasses, and the temple 405 of the eyeglasses is understood to be in a non-expanded state. To ensure that the temples 405 remain stably in the first position, the elastic members may be deformed to apply a force to the second member 200. When an external force is applied to the glasses, causing the temples 405 to be stretched out, the relative distance between the two temples 405 increases to fit the head circumference of different users. As the temple 405 expands, the second member 200 rotates about the first rotational axis 201 relative to the first member 100, and the second member 200 causes the resilient member to continue to deform until the second member 200 rotates to the second position. Since the engaging portion 102 acts on the first abutting portion 101 or the second abutting portion 202, the second member 200 is limited to the second position and cannot rotate further, the deformation amount of the elastic member reaches the maximum, and the temple 405 is stretched out to the maximum. After the second member 200 is moved from the first position, either between the first position and the second position or in the second position, the resilient member is capable of applying a force to the second member 200 under deformation such that the second member 200 is capable of returning from the second position to the first position in the absence of an external force.

While the above describes the change in the elastic member during rotation of the second member 200 by way of example of glasses, it will be appreciated that similar understanding is possible when the spindle mechanism is used in other devices.

The following describes the specific structure of the spindle mechanism of the present application in terms of various embodiments. For convenience of description, the second member 200 is referred to as being stretched when rotated from the first position to the second position, and the second member 200 is referred to as being reset when rotated from the second position to the first position. In addition, "upper", "lower", "left" and "right" refer to positions in the drawings.

Example 1

As shown in fig. 19 to 21, the fitting portion 102 in the first embodiment is formed in the first member 100, one end of the elastic body abuts against a portion of the second member 200 for acting with the first abutting portion 101 of the first member 100, and the other end abuts against a portion of the first member 100 opposite to the first abutting portion 101; the first shaft 201 is adjacent to the mating portion 102 relative to the elastomer.

With continued reference to fig. 19-21, the elastomer includes a compression spring 210, the compression spring 210 being expandable and contractible in a direction substantially perpendicular to the axial direction of the first rotational shaft 201. The second member 200 includes a pivot portion 203, the second abutting portion 202 is located on a first side of the pivot portion 203, a portion of the second side of the pivot portion 203 corresponding to the first abutting portion 101 of the first member 100 is provided with a spring seat 204, one end of a compression spring 210 is located on the spring seat 204, a portion of the second side of the pivot portion 203 corresponding to the mating portion 102 of the first member 100 includes a shaft seat 205, and the first rotating shaft 201 passes through the shaft seat 205.

For example, the outer side wall, the front side wall, and the inner side wall of the first member 100 in fig. 20 and 21 define a cavity, an upper portion of a left side wall 301 (i.e., an outer side wall) of the cavity forms a first abutment portion 101, and a lower portion of the left side wall 301 is inclined outward to form an engagement portion 102. In this example, the first abutment 101 may be planar, and the mating portion 102 may be beveled, as opposed. The upper portion of the second member 200 forms a pivot portion 203, the left side of the pivot portion 203 (the side close to the left side wall 301, which may also be understood as facing the left side wall 301) being a first side, and forms a second abutment portion 202, the second abutment portion 202 corresponding to both the first abutment portion 101 and the mating portion 102. In this example, the second abutment 202 may be planar. The second side of the pivot portion 203 faces away from the first abutment portion 101, which may be referred to as the right side. The right upper portion of the pivot portion 203 is recessed to form a recess, and the spring seat 204 is provided in the recess. The spring seat 204 in this embodiment may be a protruding column, and one end of the compression spring 210 may be sleeved on the protruding column. 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 thereof, 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 relatively close to the mating portion 102 with respect to the compression spring 210 (elastomer), so that the compression spring 210 is convenient to apply a restoring force to the second member 200 to rotate from the second position toward the first position.

The compression spring 210 may be provided in a plurality, for example, two, juxtaposed to provide a stable and balanced return force for the second member 200.

As shown in fig. 20, when the second member 200 is in the first position, the compression spring 210 applies a force to the second member 200 to press the second member 200 against the first member 100, and the second contact portion 202 of the second member 200 is brought into contact with the first contact portion 101 of the first member 100, and can be held in the first position. When a force is applied to the second member 200 that causes it to expand to the left (outward) in the drawing, the second member 200 rotates until its second abutment 202 abuts against the mating portion 102 on the first member 100, see fig. 21, the compression spring 210 is still in a compressed state, and applies a force to the second member 200 so that it has a tendency 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 on the second member 200. The elastic member includes elastic posts respectively located at opposite sides of the first rotation shaft 201, and the elastic posts 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 the different sides of the first rotation shaft 201 are elastically deformed in opposite directions. The second member 200 is provided with a restoring force rotated from the second position toward the first position by the elastic column elastically deformed in the opposite direction.

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 passing through the first protrusion 206 and being fixed to the first member 100 at both ends, and the second elastic column 212 passing through the second protrusion 207 and being fixed to the first member 100 at both ends.

With continued reference to fig. 24 and 25, the first component 100 includes a first ear panel 103 and a second ear panel 104 disposed in a vertically opposed relationship. The first rotation shaft 201 passes through the second member 200, and both ends are respectively connected to the two ear plates. 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 ear 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 shaft 201 is parallel to the first abutting portion 101 and the second abutting portion 202. The first and second elastic columns 211 and 212 are in an undeformed state (when the second member 200 is in the first position), both of which are parallel to the first rotation axis 201.

As shown in fig. 26 to 28, when the second member 200 is rotated from the first position shown in fig. 26 and 27 to the second position shown in fig. 28, that is, the second member 200 is rotated to the left (outward) shown in fig. 26 and 28, the first protrusion 206 and the second protrusion 207 of the second member 200 respectively drive the elastic column passing therethrough to elastically deform. The first protrusion 206 located on the left side (outside) in fig. 26 and 28 drives the first elastic column 211 located on the left side to elastically deform toward the upper part (when the pivot mechanism is applied to the smart glasses, the first elastic column 211 is close to the front frame of the glasses) as shown in the drawing. The second protrusion 207 located on the right side (inner side) in fig. 26 and 28 drives the second elastic column 212 located on the right side to elastically deform toward the lower part (the first elastic column 211 is away from the front frame when the pivot mechanism is applied to the smart glasses) as shown in the drawing. The elastic post is deformed to have the characteristic of restoring deformation so as to realize the resilience force when the second member 200 is outwardly expanded.

Example III

As shown in fig. 31 to 33, the fitting portion 102 is formed on the second member 200. The first and second members 100, 200 define the receptacle 106. The elastic member is an elastic cushion 213, and the elastic cushion 213 is disposed in the accommodating portion 106 and abuts against the first member 100 and the second member 200 at the same time. When the second member 200 is rotated from the first position to the second position, i.e., outwardly expanded to the left in the drawing to be positioned at the second position, the second member 200 presses the elastic pad 213 to be elastically deformed (see fig. 33), accumulates elastic potential energy, and thus obtains a resilient force to provide a restoring force to the second member 200 rotated from the second position toward 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 resilience of the elastic pad 213.

With continued reference to fig. 31, the first member 100 has a cavity, and one end of the second member 200 extends into the cavity and forms a receiving portion 106 with a left side wall 301 (outer side wall) of the cavity. An end surface of the second member 200 extending into one end of the cavity forms a second abutment 202. The surface of the first member 100 opposite to the second abutting portion 202 forms a first abutting portion 101 and a mating portion 102. That is, the bottom of the accommodating chamber forms the first abutting portion 101 and the fitting portion 102. The first side of the elastic cushion 213 is attached to a side of the second member 200 located in the accommodating portion 106, and the second side of the elastic cushion 213 is attached to a side wall 301 of the accommodating cavity opposite to the side of the second member 200. To fix the elastic pad 213, the elastic pad 213 may be adhered to the side wall 301 of the cavity.

Example IV

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

In the fourth embodiment, the outward-stretching resilience of the second member 200 can be achieved by the elastic sheet 214. The elastic piece 214 may be fixed to the side wall 301 of the accommodating portion 106 of the first member 100 by means of adhesion or welding, and the elastic piece 214 is compressed when the second member 200 is rotated outward, thereby obtaining the elastic force.

Example five

As shown in fig. 37 to 39, the elastic member includes a spring piece group 215 formed by stacking a plurality of spring pieces in sequence; the spring piece group 215 acts on an end surface of the second member 200 adjacent to the second abutting portion 202. When the second member 200 is in the second position, the spring plate set 215 deforms to provide a restoring force to the second member 200 that rotates from the second position toward the first position.

With continued reference to fig. 37 to 39, the first member 100 has a cavity, the upper portion of the left side wall 301 of which forms the first abutment portion 101, and the lower portion of the left side wall 301 of which forms the engagement portion 102 inclined outward. The first end of the second member 200 extends into the cavity, and the spring plate set 215 is located between the first end of the second member 200 and the upper sidewall 301 of the cavity. The spring plates are sequentially stacked from top to bottom. The first end of the second component 200 protrudes from the side of the left side wall 301 away from the cavity, where the side of the left side wall 301 is close to the cavity, so as to form a protrusion, and the elastic piece group 215 acts on the end surface of the protrusion. The first shaft 201 is located below the protrusion and is located as far away from the left side wall 301 of the cavity as possible, so that the spring assembly 215 provides a force to the second component 200 to return the second component from the second position to the first position. In order to provide a deformation space for the elastic sheet set 215, the top side wall of the accommodating cavity defines a recess to deform the free end (acting on the end face of the protrusion) of the elastic sheet set 215, and a mounting portion is further disposed on the top side wall of the accommodating cavity to fix the fixed end of the elastic sheet set.

The first member 100 of the above embodiments may include a first member body and a rotation shaft connection. The shaft connector and the first member body may be an integral piece. Alternatively, the shaft connector is connected to the first member body. The first abutting portion 101 is formed on the rotating shaft connecting member, and the second member 200 is rotatably connected to the rotating shaft connecting member through the first rotating shaft 201.

All of the elastic members in the above embodiments may 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 points of the elastic column are not collinear, i.e., the holes of the elastic column fixed by the first ear plate 103 and the second ear plate 104 and the protruding portion are not coaxial for penetrating the hole of the elastic column, so as to provide the pre-tightening force in advance.

As shown in fig. 40 to 59, the embodiment of the present application further provides a pair of glasses 400. The glasses 400 include a frame 404 and a temple 405, and the glasses 400 further include a rotating shaft mechanism according to any of the above embodiments; or the eyeglass 400 further comprises a connection 420 for the eyeglass of any of the embodiments described above. The frame 404 and the temple 405 are connected by a pivot mechanism or connection 420.

When the glasses 400 include two sets of rotating shaft mechanisms, the first parts 100 of the two sets of rotating shaft mechanisms are respectively fixed on the glasses frame 404, and the two glasses legs 405 are respectively hinged on the second parts 200 of the two sets of rotating shaft mechanisms. Because the second component 200 can rotate left and right relative to the first component 100, the two temples 405 connected to the second component 200 can be broken outwards, so that the distance between the two temples 405 can be adjusted to adapt to the head circumference of different wearers. In addition, the temples 405 are hinged to the second member 200 so that the temples 405 can be folded for easy storage.

When the glasses 400 include the connection mechanism 420, the connection mechanism 420 is two sets, the first parts 100 of the two sets of connection mechanisms 420 are respectively fixed to the frame 404, and the two legs 405 are respectively hinged to the third parts 300 of the two sets of connection mechanisms 420. Because the second component 200 can rotate left and right relative to the first component 100, the two temples 405 can be broken outwards, so that the distance between the two temples 405 can be adjusted to adapt to the head circumference of different wearers. Since the third member 300 can be rotated up and down relative to the second member 200, the two temples 405 can be adjusted up and down to accommodate the height of the ears of different wearers. In addition, the temples 405 are hinged to the third member 300 so that the temples 405 can be folded for easy storage. The glasses 400 of the embodiment of the application have strong applicability, convenient wearing and good user experience.

As shown in fig. 41, the frame 404 of the glasses 400 and the first member 100 may be in a separate structure. 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 connection member such as a screw 407. Of course, the frame 404 may be directly used as the first member 100; or the frame 404 as part of the first component 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. To ensure wear resistance and fatigue resistance during rotation, the first member 100 may be made of aluminum alloy or stainless steel or polyoxymethylene POM material. When the frame 404 and the first member 100 are integrally formed, they may both be of a metallic material and directly integrally molded for ease of assembly.

As shown in fig. 40, the glasses 400 are smart glasses, and the smart glasses 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 intelligent glasses can be AR glasses, VR glasses and other head-mounted display devices. The image source module 402 is used for displaying an image projected into a human eye, and the optical module 403 plays a role of changing an optical path and the like.

The manner in which the temple 405 is connected to the third member 300 and the manner in which the data line 408 is routed are described in connection with various embodiments.

Example 1

When the glasses 400 are smart glasses, a frame 404 (display body) of the smart glasses is typically connected to a temple 405 by a data line 408. As shown in fig. 42 and 43, the data line 408 extends from the display body, through the third member 300, and to the temple 405. As shown in fig. 43, 45 and 46, the glasses 400 further include a folding hinge 409 and a hinge holder 410. The hinge fixing base 410 is fixed on the inner side of the temple 405, and for convenient disassembly, the hinge fixing base 410 can be clamped on the temple 405 and fixed by 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 fixing base 410, so that the temple 405 can rotate with respect to the third member 300. The glasses leg 405 is hinged with the third component 300 through the folding hinge 409, the glasses leg 405 can be folded and unfolded, and the glasses leg 405 is convenient to store and carry after being folded.

Continuing with fig. 46, the folding hinge 409 includes a hinge portion 411 and a third rotation shaft 412, the hinge portion 411 having a through hole 413 and a cutout 414 (see fig. 49) penetrating both axial ends thereof and communicating with the through hole 413. The third rotation shaft 412 penetrates through the through hole 413 and is tightly fitted with the through hole 413 for providing rotation damping to the folding hinge 409.

With continued reference to fig. 45 and 46, the portion of the data line 408 that extends into the temple 405 may be secured within the temple 405 by a hinge mount 410. That is, the data line 408 is positioned between the temple 405 and the hinge mount 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 twisting, and the stability is improved.

As shown in fig. 47 and 48, the glasses 400 further include a connector cover 415 and a temple cover 416, wherein the connector cover 415 is disposed on the third component 300 and is used for covering the data line 408 passing through the third component 300. The temple cover 416 is disposed on the temple 405 and is used to cover the data line 408 in the temple 405. The cover plate may be attached to the third member 300 or the temple 405 using glue or a snap fit. The opposite ends of the connector cover 415 and the temple cover 416 are flexibly connected so that the connector cover 415 and the temple cover 416 can rotate relative to each other and fold along with the temple 405, and the connector cover and the temple cover 416 also bend along with the connector cover and the temple cover at the joint of the connector cover and the temple cover 416 so as not to interfere with the folding of the temple 405. By flexible connection is meant a relatively rigid connection, which is capable of rotating at the connection. For example by means of parts capable of elastic or flexible deformation, such as by means of a silicone, rubber, flexible tape, etc. Of course, the connection between the connector cover 415 and the temple cover 416 may also be rotationally coupled to facilitate rotation as the temple 405 is bent without affecting the bending of the temple 405. Of course, the connector cover 415 and the temple cover 416 may also be a clearance fit, and when the temple 405 is switched between folded and unfolded, the ends of the connector cover 415 and the temple cover 416 opposite to each other do not interfere, and thus do not affect the unfolding and folding of the temple 405. The unfolded state and 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 pivotally 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 have frame structures with opposite ends adapted, the end of the temple 405 is covered outside the end of the third member 300, and the upper side wall 301 of the temple 405 and the upper side wall 301 of the third member 300 are respectively provided with corresponding upper assembly holes. The lower side wall 301 of the temple 405 and the lower side wall 301 of the third member 300 are respectively provided with corresponding lower fitting holes. The number of pins 417 may be two, and the two pins 417 are respectively installed in the upper and lower assembly holes. The portion of the pin 417 extending out of the assembly hole is provided with a snap spring 418 to limit the pin 417 to the assembly hole.

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

As shown in fig. 53, after the temple 405 and the third member 300 are hinged, the data line 408 extends from the frame 404 through the third member 300 to the temple 405. As shown in fig. 56 and 57, the glasses 400 further include a connector cover 415 and a temple cover 416 that are capable of positioning the data line 408 within the third-component 300 and the temple 405. The connection manner, the mating manner, etc. of the connector cover 415 and the temple cover 416 may be the same as those of 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 convenient to store and carry after folding.

The glasses 400 provided by the embodiment of the application can realize the outward stretching, the up-and-down swinging and the folding, and the use experience of wearing the glasses 400 by a user is improved. The outward-stretching rebound function is realized through the elastic column, the compression spring 210, the elastic cushion block 213, the elastic sheet group 215 and the like, and the butterfly-shaped elastic sheet 306 provides swing damping, so that wearing is more comfortable. The function that the data line 408 passes through from inside and the whole structure is sealed is realized through reasonable structural arrangement.

The above description is intended to be illustrative and not limiting, and variations, modifications, alternatives, and variations of the above embodiments may be made by those of ordinary skill in the art within the scope of the present disclosure. Also, the above examples (or one or more aspects 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. The scope of the application should be determined with reference to the appended claims, along with the full scope of equivalents to which such claims are entitled.
