Description

[Technical Field]

[0001] The present application relates to the technical field of eyeglasses, and more particularly to pivot mechanisms and eyeglasses including pivot mechanisms. [Background technology]

[0002] With the development of technologies such as virtual reality (VR), augmented reality (AR), and mixed reality (MR), more and more smart wearable devices are becoming familiar to people. Among these, smart glasses are the most well-known. The connection structure of the frame of smart glasses can be roughly divided into two types. One type has temples and a frame that are rigidly connected or are a single piece. This connection mode makes the smart glasses unable to be folded, making the smart glasses uncomfortable to wear and not firmly fixed after wearing. The other type has temples and a frame that are hingedly connected. While the temples can be folded, they cannot be adjusted in multiple directions when unfolded, and they have poor damping and springback effects. This makes the smart glasses uncomfortable to wear and not firmly fixed after wearing. Summary of the Invention

DETAILED DESCRIPTION OF THE INVENTION

[0010] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the embodiments of the present application will be described clearly and completely below with reference to the drawings of the embodiments of the present application. Obviously, the described embodiments are not all the embodiments but only some of the embodiments of the present application. Based on the described embodiments of the present application, all other embodiments that can be obtained by those skilled in the art without inventive efforts belong to the scope of the claims of the present application.

[0011] Unless otherwise defined, technical or scientific terms used herein shall have their ordinary meaning as understood by those of ordinary skill in the art to which this application pertains. As used herein, the terms "first," "second," and similar terms do not denote any order, quantity, or importance, but are used only to distinguish between different components. Similar terms, such as "comprise" or "comprises," mean that the element or object appearing before the term covers the element or object listed thereafter and its equivalents, but does not exclude other elements or objects. Similar terms, such as "connect" or "coupled," are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. Terms such as "top," "bottom," "left," and "right" are used only to describe relative positions, and if the absolute positions of the objects described are changed, their relative positions may also change accordingly.

[0012] For clarity and conciseness of the following description of the present embodiments, the present application omits detailed descriptions of known functions and components.

[0013] As shown in FIGS. 1 to 18 , an embodiment of the present application provides a connection mechanism for eyeglasses. The eyeglasses may include a frame that houses lenses and temples. The connection mechanism includes a first member 100, a second member 200, and a third member 300. The first member 100 is used to connect to the frame. The second member 200 is rotatably connected to the first member 100 via a first rotation shaft 201, and the second member 200 is rotatable in a first direction relative to the first member 100. The third member 300 is used to connect to the temples. The third member is rotatably connected to the second member 200 via a second rotation shaft 305, and the third member 300 is rotatable in a second direction different from the first direction relative to the second member 200. The axial direction of the second rotation shaft 305 is different from the axial direction of the first rotation shaft 201. The above structure allows the temples to open and close in a first direction and swing in a second direction.

[0014] The first and second directions are both rotation directions that form an arc, and the first and second directions intersect like a cross. The rotation of the second member 200 relative to the first member 100 may be opening and closing (i.e., opening and closing outward), and the rotation of the third member 300 relative to the second member 200 may be swinging up and down. It can be understood that the frame can be defined as having a longitudinal direction and a width direction. When a user wears the glasses, the longitudinal direction of the frame is approximately the same as the direction of the line connecting the user's left and right eyes, and the width direction of the frame is approximately the same as the user's up and down direction. The "left and right" direction here can be understood as the longitudinal direction of the frame, and the "up and down" direction can be understood as the width direction of the frame.

[0015] When the connection mechanism according to the embodiment of the present application is applied to eyeglasses, it is possible to realize movement of the temples in two different directions, and the two temples of the eyeglasses can be opened outward (bent outward) to fit the head circumference of different wearers and improve the fit. In addition, the two temples of the eyeglasses can also be swung up and down to achieve vertical adjustment so as to fit the ear height of different wearers and improve the usability of the eyeglasses.

[0016] It can be understood that the second member 200 and the third member 300 in the embodiment of the present application may be applied to the eyeglasses separately from the first member so that the temples of the eyeglasses can swing up and down. In this example, the second member 200 can be connected to the frame via another member.

[0017] In one example, the present disclosure provides eyeglasses that can include a frame that houses lenses, a rotation axis (e.g., a second rotation axis), an intermediate connector (e.g., a second member), and temples. The intermediate connector is connected to the frame, and the temples are rotatably connected to the intermediate connector via the rotation axis, with the axial direction of the rotation axis extending essentially along the longitudinal direction of the frame. The temple members may be provided with first teeth, and the intermediate connector is provided with second teeth that match the first teeth. When the temples rotate relative to the intermediate connector, the first teeth and the second teeth elastically contact and move relative to each other, providing rotational damping.

[0018] Optionally, by combining Figures 3 to 6 with Figures 9 and 10, the third member 300 and the second member 200 may be rotatably connected around the second rotation shaft 305 as the rotation axis, or a boss 310 (described in detail later) on the third member 300 may be used as the rotation axis to connect the boss 310 to the third member 300 and to drill the second member 200. For example, the second member 200 is fitted to the boss 310 and is rotatable around the boss 310. In one example, the boss 310 may be an integral member extending from the third member 300.

[0019] Optionally, in combination with Figures 11 to 12, the second rotation axis 305 may be drilled through the third member 300 and the second member 200 so that the third member 300 and the second member 200 are rotatably connected, and the third member 300 is rotatable around the second rotation axis 305.

[0020] Optionally, the second rotation shaft 305 may be fitted with a dish-shaped elastic sheet 306 for providing rotational damping to the third member 300 .

[0021] The structure of the connection mechanism of the present invention will be specifically described below with reference to different embodiments.

[0022] [Example 1] The third member 300 has a position regulating portion 303 that interacts with the first member 100 or the second member 200 of the pivot shaft mechanism to regulate the rotation angle of the third member 300 when the third member 300 rotates relative to the second member 200.

[0023] As shown in Figures 7 and 8, one end of the third member 300 faces the first member 100, and there is a first gap 308 between the two. When the third member 300 rotates relative to the second member 200, the one end of the third member 300 interacts with the first member 100 to regulate the rotation angle of the third member 300, and the one end of the third member 300 forms a position regulating portion 303.

[0024] 7 and 8, the upper and lower sides of the first member 100 facing one end of the third member 300 respectively form an upper position restriction surface 108 and a lower position restriction surface 109. The position restriction portion 303 of the third member 300 includes an upper position restriction portion and a lower position restriction portion. The upper position restriction surface 108 and the upper position restriction portion of the first member 100 restrict the angle of upward swing of the third member 300 (see FIG. 7), and the lower position restriction surface 109 and the lower position restriction portion of the first member 100 restrict the angle of downward swing of the third member 300 (see FIG. 8).

[0025] Optionally, the first member 100 includes a first member body and a rotary shaft connecting member connected to the first member body. The upper and lower sides of the rotary shaft connecting member facing one end of the third member 300 form upper and lower position restricting surfaces, respectively, to restrict the swing angle of the third member 300.

[0026] 1 to 8, third member 300 includes a frame-like structure surrounded by both side walls 301 and a bottom wall 302, and second member 200 is provided within the frame-like structure. There are second gaps 309 between both side walls 301 and second member 200, and when third member 300 rotates relative to second member 200, second member 200 can interact with both side walls 301 to regulate the rotation angle of third member 300, and both side walls 301 form position regulation portions 303. Note that, although the second gap 309 shown in the illustration of this embodiment is large, this is merely an example, and if the size of the second gap 309 is adjusted or bumps 311, 312 are provided in the second gap 309, when the third member 300 rotates, the second member 200 will interfere with both side walls 301 of the third member 300 and the bumps 311, 312, thereby preventing further rotation of the third member 300. The second member 200 can form a position restriction on the rotation of the third member 300, thereby restricting the rotation range of the third member 300.

[0027] 1, bumps 311 are provided on the bottom wall 302 near both side walls 301 to define the second member 200 between the two bumps 311, and when the third member 300 rotates relative to the second member 200, the rotational displacement of both members is defined. Also, in the example shown in FIG. 2, bumps 312 are provided on both side walls extending opposite each other to define the rotational displacement of both members when the third member 300 rotates relative to the second member 200.

[0028] 3 to 8, the bottom wall 302 is provided with first toothed portions 304, and the second member 200 is provided with second toothed portions 217 that match the first toothed portions 304. When the third member 300 rotates relative to the second member 200, the first toothed portions 304 and the second toothed portions 217 elastically contact each other and move relative to each other, thereby damping the rotation. By providing the meshing first toothed portions 304 and second toothed portions 217, it is possible to increase the clicking sensation during the rotation process and to stop the rotation at an angle.

[0029] The second toothed portion 217 includes a plurality of teeth, with a tooth gap formed between adjacent teeth. The first toothed portion 304 may include a plurality of teeth (with a tooth gap formed between adjacent teeth) or may include a single tooth. When the connecting member 300 (third member) is positioned as shown in FIG. 7, the first toothed portion 304 meshes with a tooth located at the bottom of the second toothed portion 217 in the figure. When the connecting member 300 (third member) is positioned as shown in FIG. 8, the first toothed portion 304 meshes with a tooth located at the top of the second toothed portion 217 in the figure. In other words, when the connecting member 300 (third member) rotates relative to the second member 200, the first toothed portion 304 meshes with a different tooth of the second toothed portion 217.

[0030] Optionally, in one example, the first tooth portion 304 and the second tooth portion 217 may be elastic, so that when the first tooth portion 304 moves relative to the second tooth portion 217, the first tooth portion 304 and the second tooth portion 217 elastically deform so that the first tooth portion 304 can be caught in a different tooth gap. Unless an external force is applied, the connecting member 300 (third member) and the second member 200 are held in that position.

[0031] Optionally, to save space, the first teeth 304 on the bottom wall 302 are teeth that protrude from the bottom wall 302, and the second teeth 217 on the second member 200 are teeth that are disposed in recesses in the second member 200.

[0032] Continuing with FIG. 5, the bottom wall 302 is provided with a boss 310 positioned within a frame-like structure, and the second member 200 is provided within the frame-like structure, with the boss 310 perforating the second member 200. In this embodiment, the boss 310 can form the rotation axis instead of the second rotation axis 305. The boss 310 is fixed relative to the third member 300. The second member 200 is fitted to the boss 310 and is rotatable around the boss 310, thereby rotatably connecting the third member 300 to the second member 200 via the boss 310. The boss 310 may have a central hole, and a pin shaft 305 is attached to the central hole of the boss 310. The dish-shaped elastic sheet 306 is pressed between the boss 310 (second rotation axis) and the head of the pin shaft 305. This allows the entire pin shaft 305, including the head, to be housed within the frame of the third member 300, improving the aesthetic appearance of the product, protecting the pin and metal fittings, and extending their service life.

[0033] 3, 4, and 6, the end of boss 310 is elongated cylindrical, the hole in second member 200 corresponding to the end of boss 310 is a circular hole, and the central hole in boss 310 of third member 300 is a circular hole, i.e., pin shaft 305 and second member 200 remain relatively stationary (they are fixed), while second member 200 can rotate around boss 310 relative to third member 300, thereby realizing the up-and-down swing function of third member 300. Furthermore, boss 310 (second rotation shaft) may be exteriorly fitted with friction sheet 307 provided between boss 310 and dish-shaped elastic sheet 306.

[0034] The dished elastic sheet 306 has elasticity and has a curved initial shape (see FIG. 9 ). When the pin shaft 305 is inserted into the corresponding hole of the second member 200, the dished elastic sheet 306 is pressed so as to be forcibly deformed into a flat surface (see FIG. 10 ). The pin shaft 305 and the corresponding hole of the second member 200 may be tightly fitted together, which prevents the pin shaft 305 from being pushed up by the repulsive force of the dished elastic sheet 306. The pin shaft 305 and the second member 200 may be fixed by caulking or welding, which similarly prevents the pin shaft 305 from being pushed up by the repulsive force of the dished elastic sheet 306. At this time, the dished elastic sheet 306 is constantly pressed, providing a damping response during the rotation process.

[0035] Optionally, in one example, when the third member 300 and the second member 200 rotate relative to each other, the first toothed portion 304 and the second toothed portion 217 also move relative to each other. When the highest points of the two toothed portions come into contact, the second member 200 is forced to move slightly outward (away from the bottom wall 302) along the axial direction of the boss 310, and when the lowest points of the two toothed portions come into contact, the second member 200 moves slightly inward (closer to the bottom wall 302) along the axial direction of the boss 310. Because the second member 200 is exteriorly fitted with a dish-shaped elastic sheet 306, when the third member 300 rotates relative to the second member 200, the first toothed portion 304 and the second toothed portion 217 can elastically come into contact with each other due to the action of deformation of the dish-shaped elastic sheet 306.

[0036] The pin shaft 305 and the dish-shaped elastic sheet 306 are fitted together to form a damping shaft. The damping shaft provides a stepless damper response. The first tooth portion 304 and the second tooth portion 217 are fitted together to provide a stepwise damper response. The damping shaft and the tooth portion may be provided simultaneously, or only the tooth portion may be provided without the damping shaft, or only the damping shaft may be provided without the tooth portion.

[0037] [Example 2] 11 to 18, Example 2 differs from Example 1 in that the second rotating shaft (pin shaft 305) penetrates the third member 300 from the outside of the third member 300 and is then connected to the second member 200. The second rotating shaft (boss 310) in Example 1 penetrates the second member 200 and the third member 300 from the inside of the third member 300. The structure of other parts of Example 2 is substantially the same as Example 1, so a detailed description will be omitted here.

[0038] The end of the pin shaft 305 is oval, the hole in the second member 200 corresponding to the pin end is an oval hole that matches with the corresponding hole, and the central hole in the boss 310 of the third member 300 is a circular hole, i.e., the pin shaft 305 and the second member 200 remain relatively stationary (they are fixed), but the third member 300 can rotate around the pin shaft 305 relative to the second member 200, thereby realizing the up-and-down swing function of the third member 300. Furthermore, the pin shaft 305 may be exteriorly fitted with a friction sheet 307 provided between the pin shaft 305 and the dish-shaped elastic sheet 306.

[0039] In this embodiment, the pin shaft 305 may be a second rotation axis 305, which penetrates the third member 300 and the second member 200 and is fixed to the second member 200, thereby allowing the third member 300 to form a rotational connection with the second member 200 around the pin shaft 305, and the third member 300 can rotate relative to the second member 200 around the second rotation axis 305.

[0040] An embodiment of the present disclosure further provides a rotating shaft mechanism. For example, as shown in FIGS. 19 to 41 , a first member and a second member are assembled via a first rotating shaft 201 to jointly form the rotating shaft mechanism. The rotating shaft mechanism may include a first rotating shaft 201, a first member 100, a second member 200, and a fitting portion 102, where the first member 100 has a first abutting portion 101. The second member 200 has a second abutting portion 202, and the second member 200 is rotatably connected to the first member 100 via the first rotating shaft 201, where the second member 200 is rotatable within a predetermined angular range relative to the first member 100, and the second member 200 has a first position and a second position. Optionally, the first member 100 or the second member 200 includes the fitting portion 102. When the mating portion 102 is formed on the first member 100, the mating portion 102 abuts against the first abutting portion 101, forming a first included angle α therebetween. When the mating portion 102 is formed on the second member 200, the mating portion 102 abuts against the second abutting portion 202, forming 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 relative to the first member 100. That is, when the mating portion 102 is formed on the first member 100, the predetermined angle range is 0° to 180°-α, and when the mating portion 102 is formed on the second member 200, the predetermined angle range is 0° to 180°-β. The values ​​of α and β can be determined based on the field and product to which the rotary shaft mechanism is actually applied, and the angle that is actually required to rotate. Furthermore, α and β may or may not be equal.

[0041] For example, when the fitting portion 102 abuts against the first abutting portion 101 (or the second abutting portion 202), the fitting portion 102 may be provided on the same member as the first abutting portion 101 (or the second abutting portion 202), with the two portions extending continuously, or the fitting portion 102 may be provided on different members, with the two portions extending continuously. It can be understood that there may be a gap between the fitting portion 102 and the first abutting portion 101 (or the second abutting portion 202).

[0042] For example, a rotating shaft mechanism can be applied to eyeglasses, where the temples 405 of the eyeglasses are connected to the second member 200 and the frame 404 of the eyeglasses are connected to the first member 100, and the second member 200 can rotate the temples 405 relative to the first member 100 and the frame 404 to allow the temples 405 to open outward, thereby allowing the eyeglasses to fit different wearer's head circumferences and making them easier to wear. For example, if the temples 405 need to open outward by 10° to 15°, the first included angle and the second included angle can be 165° to 170°, respectively.

[0043] It can be understood that the rotating shaft mechanism according to the embodiment of the present disclosure can be applied alone to eyeglasses, allowing the temples of the eyeglasses to open further outward after being unfolded. The rotating shaft mechanism according to the embodiment of the present disclosure may also be applied to eyeglasses by forming a connection mechanism together with the third member in the above-mentioned embodiment, allowing the temples of the eyeglasses to open further outward after being unfolded, as well as to swing up and down.

[0044] In one example, the present disclosure provides eyeglasses that can include a frame that houses lenses and temples. The frame itself can be a first member, a second member can be rotatably connected to the frame via a rotation axis, and the temples can be connected to the frame via the second member. The frame has a first flat surface located on the inner wall of the frame and a beveled surface that forms an included angle with the first flat surface. The second member has a second flat surface that includes a first portion corresponding to the first flat surface and a second portion corresponding to the beveled surface. The second member can be rotated relative to the frame via the rotation axis between a first position and a second position. In the first position, the first flat surface and the first portion of the second flat surface are in close contact, and in the second position, the beveled surface and the second portion of the second flat surface are in close contact.

[0045] When the fitting portion 102 is formed on the first member 100 and the second member 200 is located at the first position, the first abutment portion 101 and the second abutment portion 202 interact with each other to hold the second member 200 at the first position. When the fitting portion 102 is formed on the first member 100 and the second member 200 is located at the second position, the fitting portion 102 and the second abutment portion 202 interact with each other to hold the second member 200 at the second position. When the fitting portion 102 is formed on the second member 200 and the second member 200 is located at the first position, the first abutment portion 101 and the second abutment portion 202 interact with each other to hold the second member 200 at the first position. The fitting portion 102 is formed on the second member 200, and when the second member 200 is located at the second position, the first abutment portion 101 and the fitting portion 102 interact with each other to hold the second member 200 at the second position.

[0046] The rotating shaft mechanism according to the embodiment of the present application provides a fitting portion on the first member 100 and the second member 200, and also provides a contact portion on the first member 100 and the second member 200, thereby allowing the second member 200 to rotate relative to the first member 100, and by allowing the fitting portion and the contact portion to act upon rotation and the contact portions to act upon each other, the second member 200 can be held in a first position or a second position after rotation, thereby realizing adjustment of the angle between the first member 100 and the second member 200.

[0047] Alternatively, by providing a slope on the first member 100 and a flat surface on the second member 200, the second member 200 can be rotated relative to the first member 100, and the slope and the flat surface can be switched between interacting with each other (e.g., the slope and the flat surface are in close contact with each other) and interacting with each other (e.g., the flat surface and the flat surface are in close contact with each other) during rotation. The terms "flat surface" and "slope" can both have essentially flat surfaces, and it can be understood that the "slope" is named after its angle relative to the term "flat surface." Alternatively, the mating portion can have a structure having a curved surface, a recess, a bump, or the like, and the abutting portion can have a structure having a curved surface, a recess, a bump, or the like.

[0048] In one example, the first abutment portion is a first plane, the second abutment portion is a second plane, and the mating portions can be arranged in one of the following configurations: the first member includes a mating portion that is a sloped surface that forms a first included angle with the first plane, and when the second member is in a first position, the first plane and the second plane are in close contact, and when the second member is in a second position, the sloped surface and the second plane are in close contact; the second member includes a mating portion that is a sloped surface that forms a second included angle with the second plane, and when the second member is in a first position, the first plane and the second plane are in close contact, and when the second member is in a second position, the sloped surface and the first plane are in close contact.

[0049] Optionally, the first abutment portion, the second abutment portion and the fitting portion may be provided in a region between the first member and the second member and may be hidden by the first member and / or the second member so as to be difficult to see from the outside.

[0050] In some embodiments, the rotary shaft mechanism may further include an elastic member provided between the first member 100 and the second member 200 for applying a restoring biasing force to the second member 200 to rotate from the second position toward the first position so that the second member 200 can return from the second position to the first position when no external force is acting.

[0051] The specific structure, installation position, and operation mode of the elastic member are not particularly limited in the present application, as long as it can apply a return biasing force to the second member 200 to rotate it from the second position toward the first position. In one example, the elastic member may be an elastic body that is deformable in a direction perpendicular to the axial direction of the first rotation shaft 201, thereby applying a return biasing force to the second member 200 to rotate it from the second position toward the first position, for example, applying the return biasing force in a direction approximately perpendicular to the axial direction of the first rotation shaft 201.

[0052] For example, in an embodiment in which the above-described rotating shaft mechanism is applied to eyeglasses, when no external force is applied to the eyeglasses, the second member 200 is in a first position, and the temples 405 of the eyeglasses are not open outward. To ensure that the temples 405 are stably held in the first position, the elastic member can be given a certain deformation, thereby applying a certain force to the second member 200. When an external force is applied to the eyeglasses and the temples 405 open outward, the relative distance between the two temples 405 increases, thereby allowing the eyeglasses to fit different head circumferences. As the temples 405 open outward, the second member 200 rotates relative to the first member 100 around the first rotating shaft 201, and the second member 200 continues to deform the elastic member until the second member 200 rotates to the second position. Because the fitting portion 102 interacts with the first abutment portion 101 or the second abutment portion 202, the second member 200 is restricted to the second position and cannot rotate any further, the amount of deformation of the elastic member reaches a maximum, and the temples 405 are accordingly opened outward to their maximum extent. After the second member 200 leaves the first position, whether it is located at a position between the first and second positions or at the second position, the elastic member can apply force to the second member 200 due to the action of deformation, and this allows the second member 200 to return from the second position to the first position when no external force is acting.

[0053] The above describes the change in the elastic member during the rotation process of the second member 200 using eyeglasses as an example, but it can be understood that the same can be understood when the above rotation axis mechanism is used in other devices.

[0054] The specific structure of the rotary shaft mechanism of the present application will be introduced below using different embodiments. For ease of explanation, the rotation of the second member 200 from the first position to the second position will be referred to as "outward opening," and the rotation of the second member 200 from the second position to the first position will be referred to as "returning." Note that "up," "down," "left," and "right" refer to positions in the drawings.

[0055] [Example 1] As shown in Figures 19 to 21, the fitting portion 102 in Example 1 is formed on the first member 100, one end of the elastic member abuts against a portion of the second member 200 that interacts with the first abutment portion 101 of the first member 100, and the other end abuts against a portion of the first member 100 that faces the first abutment portion 101, and the first rotation axis 201 is closer to the fitting portion 102 than the elastic member.

[0056] 19 to 21 , the elastic member includes a compression spring 210 that can expand and contract in a direction approximately perpendicular to the axial direction of the first rotation shaft 201. It can be understood that in this embodiment, another type of elastic member different from the compression spring 210 may be selected. The second member 200 includes a pivot portion 203, a second abutting portion 202 is located on a first side of the pivot portion 203, a spring seat 204 is provided on a portion of the second side of the pivot portion 203 that corresponds to the first abutting portion 101 of the first member 100, one end of the compression spring 210 is positioned on the spring seat 204, and a portion of the second side of the pivot portion 203 that corresponds to the fitting portion 102 of the first member 100 includes an axis seat 205 through which the first rotation shaft 201 is drilled.

[0057] For example, in FIGS. 20 and 21 , the outer wall, front wall, and inner wall of the first member 100 define a storage chamber, and the upper portion of the left side wall 301 (i.e., the outer wall) of the storage chamber forms a first abutment portion 101, and the lower portion of the left side wall 301 is inclined outward to form a fitting portion 102. In this example, the first abutment portion 101 may be flat, while the fitting portion 102 may be inclined. The upper portion of the second member 200 forms a pivot portion 203, and the left side of the pivot portion 203 (closer to the left side wall 301, which can also be understood as the side facing the left side wall 301) is the first side, and forms a second abutment portion 202 that corresponds to both the first abutment portion 101 and the fitting portion 102. In this example, the second abutment portion 202 may be flat. The second side of the pivot portion 203 is spaced from the first abutment portion 101 and can be referred to as the right side. The upper right portion of the pivot portion 203 is recessed inward, and a spring seat 204 is provided in the recess. In this embodiment, the spring seat 204 may be a boss, and one end of the compression spring 210 can be fitted to the boss. The lower right portion of the pivot portion 203 (the portion away from the front wall) is formed as a protrusion relative to the upper portion. The protrusion serves as a shaft seat 205 for the first rotating shaft 201, and the first rotating shaft 201 penetrates the shaft seat 205. This positioning position makes the first rotating shaft 201 closer to the fitting portion 102 than the compression spring 210 (elastic member), making it easier for the compression spring 210 to apply force and provide a return biasing force to the second member 200 to rotate it from the second position toward the first position.

[0058] The compression springs 210 may be multiple, for example two, arranged in parallel, thereby providing a stable and balanced restoring force to the second member 200 .

[0059] 20, when the second member 200 is located at the first position, the compression spring 210 applies a biasing force to the second member 200 to cause it to abut against the first member 100, so that the second abutment portion 202 of the second member 200 and the first abutment portion 101 of the first member 100 are in close contact with each other, and the second member 200 can be held at the first position. When a biasing force is applied to the second member 200 to open it outward to the left (outward) in the figure, the second member 200 rotates until the second abutment portion 202 comes into close contact with the fitting portion 102 of the first member 100, and as shown in FIG. 21, the compression spring 210 remains in a compressed state and applies a biasing force to the second member 200 so as to cause it to have a tendency to return from the second position to the first position.

[0060] [Example 2] As shown in Figures 22 to 30, the fitting portion 102 is formed on the second member 200. The elastic member includes elastic pillars located on opposite sides of the first rotation shaft 201, and the elastic pillars each penetrate the second member 200. When the second member 200 switches from the first position to the second position, the elastic pillars located on different sides of the first rotation shaft 201 elastically deform in opposite directions. The elastic pillars elastically deforming in opposite directions apply a restoring force to the second member 200 that rotates it from the second position toward the first position.

[0061] 24 and 25 , the second member 200 includes a first protrusion 206 located on a first side thereof and a second protrusion 207 located on a second side thereof. The elastic pillars include a first elastic pillar 211 that passes through the first protrusion 206 and has both ends fixed to the first member 100, and a second elastic pillar 212 that passes through the second protrusion 207 and has both ends fixed to the first member 100.

[0062] 24 and 25, the first member 100 includes a first ear plate 103 and a second ear plate 104 arranged opposite each other. A first rotation shaft 201 passes through the second member 200 and is connected at both ends to the two ear plates. Two elastic columns are fixed at both ends to the two ear plates.

[0063] As shown in Fig. 22, the first member 100 further includes an end plate 105, and the two ear plates are both provided on the plate surface (surface) of the end plate 105, with the plate surface forming a first abutment portion 101. One end of the second member 200 faces the plate surface and forms a second abutment portion 202. The first rotation axis 201 is parallel to the first abutment portion 101 and the second abutment portion 202. The first elastic pillar 211 and the second elastic pillar 212 are both parallel to the first rotation axis 201 in an undeformed state (when the second member 200 is located at the first position).

[0064] 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, when the second member 200 rotates to the left (outward) as shown in Fig. 26 and 28, the first protrusion 206 and the second protrusion 207 of the second member 200 elastically deform, respectively, carrying with them the perforated elastic posts. The first protrusion 206 located on the left side (outside) in Fig. 26 and 28 elastically deforms the first elastic post 211 located on the left side toward the top in the drawings (in the direction in which the first elastic post 211 approaches the front frame of the glasses when the rotation axis mechanism is applied to smart glasses). 26 and 28, the second protrusion 207 located on the right side (inner side) causes the second elastic pillar 212 located on the right side to be elastically deformed downward in the drawings (in the direction in which the first elastic pillar 211 moves away from the front frame when the rotation axis mechanism is applied to smart glasses). The elastic pillar has the characteristic of recovering from deformation after deformation, thereby realizing a repulsive force when the second member 200 opens outward.

[0065] [Example 3] As shown in FIGS. 31 to 33 , the fitting portion 102 is formed in the second member 200. The first member 100 and the second member 200 define the accommodation portion 106. The elastic member is an elastic spacer 213, which is provided in the accommodation portion 106 and abuts against both the first member 100 and the second member 200 at the same time. When the second member 200 rotates from the first position to the second position, i.e., when it opens outward toward the left side in the figure to the second position, the second member 200 presses and elastically deforms the elastic spacer 213 (see FIG. 33 ), storing elastic energy and obtaining a repulsive force, which thereby applies a restoring force to the second member 200 to rotate it from the second position toward the first position. In other words, the repulsive force of the elastic spacer 213 provides the repulsive force that returns the second member 200 from the second position to the first position.

[0066] Continuing with FIG. 31, first member 100 has a storage chamber, and one end of second member 200 protrudes into the storage chamber, forming storage section 106 between the end and left side wall 301 (outer wall) of the storage chamber. The end face of the one end of second member 200 protruding into the storage chamber forms second contact portion 202. The surface of first member 100 facing second contact portion 202 forms fitting portion 102 with first contact portion 101. In other words, the bottom of the storage chamber forms fitting portion 102 with first contact portion 101. A first side surface of elastic spacer 213 is in close contact with one side surface of second member 200 located within storage section 106, and a second side surface of elastic spacer 213 is in close contact with the surface of side wall 301 of the storage chamber facing one side surface of second member 200. To fix the elastic spacer 213, the elastic spacer 213 can be attached to the surface of the side wall 301 of the containing chamber.

[0067] [Example 4] 34 to 36, the fourth embodiment differs from the third embodiment only in that elastic spacer 213 is replaced with elastic sheet 214. Elastic sheet 214 is provided in accommodating portion 106, and when second member 200 is located at the second position, elastic sheet 214 deforms to apply a restoring force to second member 200 to rotate second member 200 from the second position toward the first position.

[0068] In the fourth embodiment, the outward opening repulsive force of the second member 200 is realized by the elastic sheet 214. The elastic sheet 214 can be fixed to the side wall 301 of the accommodating portion 106 of the first member 100 by pasting or welding, and when the second member 200 rotates outward, the elastic sheet 214 is compressed to generate the repulsive force.

[0069] [Example 5] 37 to 39, the elastic member includes an elastic sheet group 215 formed by sequentially stacking a plurality of elastic sheets, and the elastic sheet group 215 acts on an end surface of the second member 200 adjacent to the second abutment portion 202. When the second member 200 is located at the second position, the elastic sheet group 215 deforms so as to apply a restoring force to the second member 200 to rotate it from the second position toward the first position.

[0070] Continuing with FIG. 37 to FIG. 39 , first member 100 has a housing chamber, and the upper part of left side wall 301 of the housing chamber forms first abutment portion 101, and the lower part of left side wall 301 of the housing chamber forms fitting portion 102 that slopes outward. A first end of second member 200 protrudes into the housing chamber, and elastic sheet group 215 is located between the first end of second member 200 and upper wall 301 of the housing chamber. Multiple elastic sheets are stacked in order from top to bottom. One side of the first end of second member 200, close to left side wall 301 of the housing chamber, protrudes to one side away from left side wall 301 of the housing chamber, forming a bump, and elastic sheet group 215 acts on the end surface of the bump. The first rotation shaft 201 is located below the bump and as far away as possible from the left side wall 301 of the accommodation chamber so that the elastic sheet group 215 applies a biasing force to the second member 200 to return it from the second position to the first position. In order to provide a space for the elastic sheet group 215 to deform, a recess is defined in the ceiling wall of the accommodation chamber so that the free ends (end faces acting on the bump) of the elastic sheet group 215 can deform, and an attachment portion is further provided in the ceiling wall of the accommodation chamber to fix the fixed ends of the elastic sheet group.

[0071] The first member 100 in each of the above-described embodiments may include a first member body and a rotary shaft connecting member. The rotary shaft connecting member and the first member body may be an integral member. Alternatively, the rotary shaft connecting member may be connected to the first member body. The first abutment portion 101 is formed on the rotary shaft connecting member, and the second member 200 is rotatably connected to the rotary shaft connecting member via the first rotary shaft 201.

[0072] All of the elastic members in the above embodiments can apply a biasing force that makes it difficult for the second member 200 to rotate. Note that when applying a biasing force to the elastic pillar in the second embodiment, the biasing force is applied early so that the three points of the top, middle, and bottom of the elastic pillar are not aligned in a straight line, i.e., the holes for fixing the elastic pillars of the first ear plate 103 and the second ear plate 104 and the holes through which the elastic pillars of the convex portions pass are not coaxial.

[0073] 40 to 59, an embodiment of the present application further provides eyeglasses 400. The eyeglasses 400 include a frame 404 and temples 405, and the eyeglasses 400 further include a pivot mechanism according to any of the above-described embodiments, or the eyeglasses 400 further include a connection mechanism 420 for eyeglasses according to any of the above-described embodiments. The frame 404 and the temples 405 are connected via the pivot mechanism or the connection mechanism 420.

[0074] When the eyeglasses 400 include a rotational axis mechanism, there are two sets of rotational axis mechanisms, and the first members 100 of the two sets of rotational axis mechanisms are fixed to the frame 404, respectively, and the temples 405 are hingedly connected to the second members 200 of the two sets of rotational axis mechanisms, respectively. Because the second members 200 are rotatable left and right relative to the first members 100, the two temples 405 connected to the second members 200 can be bent outward, thereby adjusting the distance between the two temples 405 to fit different wearer's head circumferences. In addition, the temples 405 are hingedly connected to the second members 200, allowing them to be folded for easier storage.

[0075] When the eyeglasses 400 include a connecting mechanism 420, the connecting mechanism 420 is provided in two sets. The first members 100 of the two sets of connecting mechanisms 420 are fixed to the frame 404, respectively, and the temples 405 are hingedly connected to the third members 300 of the two sets of connecting mechanisms 420, respectively. The second members 200 are rotatable left and right relative to the first members 100, allowing the two temples 405 to bend outward, thereby adjusting the distance between the two temples 405 to fit different wearers' head circumferences. The third members 300 are rotatable up and down relative to the second members 200, allowing the two temples 405 to be adjusted up and down to fit different wearers' ear heights. Furthermore, the temples 405 are hingedly connected to the third members 300, allowing the temples 405 to be folded for easy storage. The eyeglasses 400 according to the embodiment of the present application are highly adaptable, easy to wear, and provide a good user experience.

[0076] As shown in FIG. 41 , the frame 404 and the first member 100 of the eyeglasses 400 may be separate structures. The frame 404 may have fixing holes 406, and the first member 100 may be fixed to the frame 404 by a connector such as a screw 407. Of course, the frame 404 may be the first member 100 itself, or the frame 404 may be a part of the first member 100, or the frame 404 and the first member 100 may be an integrated member. The frame 404 may be made of a plastic material such as ABS / PC. The first member 100 may be made of aluminum alloy, stainless steel, or polyoxymethylene (POM) to withstand wear and fatigue during rotation. When the frame 404 and the first member 100 are an integrated member, both may be made of metal materials and are directly molded integrally, facilitating assembly.

[0077] As shown in Fig. 40, 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 smart glasses are head-mounted displays such as AR glasses and VR glasses. The image source assembly 402 is used to display an image projected to a person's eyes, and the optical assembly 403 plays a role such as changing the light path.

[0078] Hereinafter, 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 will be described with reference to different embodiments.

[0079] [Example 1] When the glasses 400 are smart glasses, a frame 404 (display body) and temples 405 of the smart glasses are typically connected by data lines 408. As shown in FIGS. 42 and 43 , the data lines 408 extend from the display body, through the third member 300, and to the temples 405. As shown in FIGS. 43 , 45 , and 46 , the glasses 400 further include a folding hinge 409 and a hinge fixing base 410. The hinge fixing base 410 is fixed to the inside of the temple 405, and for easy removal, the hinge fixing base 410 can be engaged with the temple 405 and fixed with a snap. 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, allowing the temples 405 to rotate relative to the third member 300. The temple 405 is hinged to the third member 300 by a folding hinge 409, and the temple 405 can be folded and unfolded, and after the temple 405 is folded, it is easy to store and carry.

[0080] Continuing with FIG. 46, folding hinge 409 includes hinge portion 411 and third rotating shaft 412, and hinge portion 411 has through-hole 413 and notches 414 that pass through both axial ends of hinge portion 411 and communicate with through-hole 413 (see FIG. 49). Third rotating shaft 412 has through-hole 413 drilled therein and is tightly fitted with through-hole 413 so as to provide rotational damping to folding hinge 409.

[0081] 45 and 46, the portion of the data line 408 extending into the temple 405 can be fixed within the temple 405 via a hinge fixing base 410. That is, the data line 408 is positioned between the temple 405 and the hinge fixing base 410. In this embodiment, there may be two hinge fixing bases 410 arranged side by side. The folding hinge 409 is assembled and fixed to each of the two hinge fixing bases 410 with two screws, thereby preventing the folding hinge 409 from twisting and improving stability.

[0082] As shown in FIGS. 47 and 48 , the eyeglasses 400 further include a connector cover 415 and a temple cover 416. The connector cover 415 is provided to cover the third member 300 and is used to seal the data lines 408 that pass through the third member 300. The temple cover 416 is provided to cover the temple 405 and is used to seal the data lines 408 inside the temple 405. The cover can be fixed to the third member 300 or the temple 405 by adhesive bonding or engagement. Opposing ends of the connector cover 415 and the temple cover 416 are flexibly connected to allow relative rotation. As the temple 405 is folded, the connector cover and the temple cover 416 are also folded at their connection points, so that folding of the temple 405 is not hindered. A flexibly connected connection means that the connection points can rotate, as opposed to a non-flexibly connected connection. For example, the connection is made using a member that is elastic and flexibly deformable, such as a connection via silicone rubber, rubber, or a flexible belt. Of course, the connector cover 415 and the temple cover 416 may be connected to each other so that they can rotate easily when the temple 405 is folded without affecting the folding of the temple 405. Of course, the connector cover 415 and the temple cover 416 may be loosely fitted together so that the opposing ends of the connector cover 415 and the temple cover 416 do not interfere with each other when the temple 405 is switched between folded and unfolded, and further so that the unfolding and folding of the temple 405 is not affected. See Figures 49 and 50 for the unfolded and folded states of the temple 405.

[0083] [Example 2] As shown in Figures 51 and 52, the temple 405 and the third member 300 are rotatably connected by the engagement of a pin 417 and a clip spring 418. For example, continuing with Figure 51, the third member 300 and the temple 405 have a frame-like structure in which opposing ends fit together, the end of the temple 405 wraps around the outside of the end of the third member 300, and corresponding upper assembly holes are formed in the upper wall 301 of the temple 405 and the upper wall 301 of the third member 300. Corresponding lower assembly holes are formed in the lower wall 301 of the temple 405 and the lower wall 301 of the third member 300. There may be two pins 417, and the two pins 417 are attached to the upper and lower assembly holes, respectively. A clip spring 418 is provided on the portion of the pin 417 that protrudes from the assembly hole so as to restrict the position of the pin 417 within the assembly hole.

[0084] The pin 417 can be interference-fitted into the assembly hole to provide rotational damping, as shown in Fig. 54. Alternatively, as shown in Fig. 55, a washer 419 is provided between the pin 417 and the assembly hole, i.e., the washer 419 is fitted over the portion of the pin 417 located within the assembly hole to provide rotational damping. Of course, the pin 417 is not limited to the pin 417 and may be replaced with another generally shaft-shaped member.

[0085] As shown in Fig. 53, after the temple 405 and the third member 300 are hingedly connected, the data wire 408 extends from the frame 404 through the third member 300 to the temple 405. As shown in Figs. 56 and 57, the eyeglasses 400 further include a connector cover 415 and a temple cover 416, which can position the data wire 408 within the third member 300 and the temple 405. The connection and fitting manner between the connector cover 415 and the temple cover 416 may be the same as in the first embodiment, and detailed description thereof will be omitted here.

[0086] As shown in Figures 58 and 59, the temples 405 are deployable and foldable relative to the third member 300, and once folded, are easy to store and carry.

[0087] The eyeglasses 400 according to the embodiment of the present application can not only open outward but also swing up and down, and are foldable, improving the user experience when wearing the eyeglasses 400. The functions of opening outward and spring back are realized by the elastic pillar, compression spring 210, elastic spacer 213, elastic sheet, elastic sheet group 215, etc., and the dish-shaped elastic sheet 306 provides swing damping, making the eyeglasses more comfortable to wear. The rational structural layout allows the data line 408 to pass through the interior, and the overall structure is sealed.

[0088] The foregoing description is illustrative rather than limiting. Those skilled in the art may change, amend, substitute, and modify the above-described embodiments within the scope of this disclosure. It is also contemplated that the above-described examples (or one or more of their solutions) may be used in combination with each other, and that these embodiments may be combined with each other in various combinations and permutations. The scope of this application should be determined with reference to the appended claims, along with the full scope of equivalents to which those claims are entitled. [Explanation of symbols]
