Abstract
Description
[0001] This is a divisional application. The original application was filed on June 17, 2022, with application number 202290000508.X, and its utility model name is Augmented Reality Glasses. The entire contents of the original application are incorporated herein by reference. Technical Field
[0002] This application relates to the field of eyewear technology, and in particular to an augmented reality eyewear. Background Technology
[0003] 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 them, smart glasses are the most well-known. The frame connection structure of smart glasses generally falls into two categories: one is a rigid connection between the temples and the frame, or a single piece. This connection method cannot be folded, resulting in poor wearing comfort and instability. The other is a hinged connection between the temples and the frame. Although the temples can be folded, the angle of the temples cannot be adjusted in multiple directions when unfolded, and there are problems with damping and rebound effects, which also easily leads to poor wearing comfort and instability. Utility Model Content
[0004] This utility model provides augmented reality glasses, including: an optical imaging system, the optical imaging system including an image source component and an optical component; a frame, the frame supporting the optical imaging system; temples; and a connecting mechanism, the connecting mechanism being connected to the frame and temples, the connecting mechanism including: a first component, the first component being connected to the frame; an elastic element, the elastic element being disposed between the first component and a second component; a second component, the second component being rotatably connected to the first component via a first pivot to realize the outward extension of the temples; and a third component, the third component being hinged to the temples to realize the folding of the temples; the third component being rotatably connected to the second component via a second pivot to realize the up-and-down swinging of the temples; the third component including: a frame-shaped structure formed by two side walls and a bottom wall, the second component being disposed within the frame-shaped structure, the two side walls having gaps with the second component, when the third component rotates relative to the second component, the second component can act with the two side walls to limit the rotation angle of the third component.
[0005] In one example, the third component also includes a protrusion in the gap, which the second component interferes with when the third component rotates, thus preventing the third component from continuing to rotate.
[0006] In one example, the bottom wall of the third component has a protruding post located within the frame structure. The protruding post passes through the second component to form a second pivot. The protruding post and the third component are fixed relative to each other. The second component is sleeved on the protruding post and can rotate around the protruding post, so that the third component is rotatably connected to the second component through the protruding post. The protruding post has a central hole, and a pin is installed in the central hole of the protruding post.
[0007] In one example, the elastic element provides a preload, making the second component less prone to rotation.
[0008] In one example, the elastic element can deform in an axial direction perpendicular to the first axis of rotation.
[0009] In one example, the elastic elements are compression springs arranged side by side.
[0010] In one example, the bottom wall of the third component has a first tooth, and the second component has a second tooth that matches the first tooth.
[0011] In one example, the augmented reality glasses also include: a data cable extending from the frame to the temple; a connector cover covering the third component to seal the data cable passing through the third component; and a temple cover covering the temple to seal the data cable inside the temple.
[0012] In one example, the connector cover and the temple cover are clearance fit.
[0013] In one example, the connector cover is shorter than the temple cover. Attached Figure Description

Detailed Implementation
[0080] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the described embodiments of this application without creative effort are within the scope of protection of this application.
[0081] Unless otherwise defined, the technical or scientific terms used in this application shall have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains. The terms "first," "second," and similar terms used in this application do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.
[0082] To keep the following description of the embodiments of this application clear and concise, detailed descriptions of known functions and known components are omitted.
[0083] like Figures 1 to 18As shown, this application embodiment provides a connection mechanism for eyeglasses. The eyeglasses may include a frame housing lenses and temples. The connection mechanism includes a first component 100, a second component 200, and a third component 300. The first component 100 is connected to the frame. The second component 200 is rotatably connected to the first component 100 via a first pivot 201, and the second component 200 is rotatable relative to the first component 100 in a first direction. The third component 300 is connected to the temples. The third component is rotatably connected to the second component 200 via a second pivot 305, and the third component 300 is rotatable relative to the second component 200 in a second direction different from the first direction. The axial direction of the second pivot 305 is different from the axial direction of the first pivot 201. With the above structure, the temples can be opened and closed in the first direction and oscillated in the second direction.
[0084] Both the first and second directions are arc-shaped rotation directions, and they form a shape resembling a cross. The rotation of the second component 200 relative to the first component 100 can be left-right opening and closing (i.e., outward opening and closing), while the rotation of the third component 300 relative to the second component 200 can be up-down swinging. It can be understood that the eyeglass frame has a length direction and a width direction. When a user wears the glasses, the length direction of the frame is basically the same as the extension direction of the line connecting the user's left and right eyes, and the width direction of the frame is basically the same as the user's up-down direction. Here, the "left-right" direction can be understood as the length direction of the frame, and the "up-down" direction can be understood as the width direction of the frame.
[0085] When the connecting mechanism of this application embodiment is applied to eyeglasses, it enables the temples to move in two different directions. That is, it allows the two temples of the eyeglasses to spread outward (bend outward) to accommodate different head circumferences of wearers and improve fit. Moreover, the two temples of the eyeglasses can also swing up and down to adjust to accommodate different ear heights of wearers and improve the performance of the eyeglasses.
[0086] It is understood that the second component 200 and the third component 300 in this embodiment can also be applied independently of the first component to eyeglasses, allowing the temples of the eyeglasses to swing up and down. In this example, the second component 200 can be connected to the frame via other components.
[0087] In one example, this disclosure provides eyeglasses that may include a frame housing lenses, a pivot (e.g., a second pivot), an intermediate connector (e.g., a second component), and temples. The intermediate connector is connected to the frame, and the temples are rotatably connected to the intermediate connector via the pivot, the pivot extending substantially along the length of the frame in an axial direction. The temple component may have a first tooth, and the intermediate connector has a second tooth adapted to the first tooth. The first and second teeth are configured to elastically contact and move relative to each other to provide rotational damping when the temples rotate relative to the intermediate connector.
[0088] Optional, combined Figure 3-6 as well as Figure 9-10 In addition to using the second pivot 305 as the pivot to rotatably connect the third component 300 and the second component 200, the protrusion 310 on the third component 300 (described in detail below) can also be used as the pivot, with the protrusion 310 connected to the third component 300 and passing through the second component 200. For example, the second component 200 is sleeved on the protrusion 310 and can rotate around the protrusion 310. In one example, the protrusion 310 can be an integral piece extending from the third component 300.
[0089] Optional, combined Figure 11-12 The second rotating shaft 305 can pass through the third component 300 and the second component 200, so that the third component 300 and the second component 200 form a rotatable connection, and the third component 300 can rotate around the second rotating shaft 305.
[0090] Optionally, a butterfly spring 306 may be fitted onto the second rotating shaft 305, which provides rotational damping for the third component 300.
[0091] The structure of the connection mechanism of this application will be specifically described below with reference to different embodiments. Example 1
[0092] The third component 300 has a limiting part 303, which is used to interact with the first component 100 or the second component 200 of the rotating shaft mechanism when the third component 300 rotates relative to the second component 200, so as to limit the rotation angle of the third component 300.
[0093] like Figure 7 and Figure 8 As shown, one end of the third component 300 is opposite to the first component 100, and there is a first gap 308 between them. One end of the third component 300 is used to act on the first component 100 when the third component 300 rotates relative to the second component 200 to limit the rotation angle of the third component 300. One end of the third component 300 forms a limiting part 303.
[0094] like Figure 7and Figure 8 As shown, an upper limit surface 108 and a lower limit surface 109 are formed on the upper and lower sides of the end of the first component 100 facing the third component 300, respectively. The limiting portion 303 on the third component 300 includes an upper limit portion and a lower limit portion. The upper limit surface 108 and the upper limit portion of the first component 100 limit the upward swing angle of the third component 300 (see...). Figure 7 The lower limit surface 109 of the first component 100 and the lower limit portion limit the angle of the lower swing of the third component 300 (see...). Figure 8 ).
[0095] Optionally, the first component 100 includes a first component body and a rotating shaft connector connected to the first component body. The upper and lower sides of the end of the rotating shaft connector facing the third component 300 are respectively formed with an upper limit surface and a lower limit surface to limit the swing angle of the third component 300.
[0096] Continue to combine Figures 1 to 8 The third component 300 includes a frame-shaped structure formed by two side walls 301 and a bottom wall 302, and the second component 200 is disposed within the frame-shaped structure. A second gap 309 exists between the two side walls 301 and the second component 200. When the third component 300 rotates relative to the second component 200, the second component 200 can interact with the two side walls 301 to limit the rotation angle of the third component 300. The two side walls 301 form limiting portions 303. It should be noted that the second gap 309 in the illustration of this embodiment is relatively large; this is only for illustrative purposes. If the size of the second gap 309 is adjusted, or if protrusions 311 and 312 are provided in the second gap 309, when the third component 300 rotates, the second component 200 will interfere with the two side walls 301 or the protrusions 311 and 312 of the third component 300, thereby hindering the continued rotation of the third component 300. The second component 200 can limit the rotation of the third component 300, thereby restricting the rotation range of the third component 300.
[0097] For example, Figure 1 In the example shown, protrusions 311 are provided on the bottom wall 302 near the two side walls 301 to constrain the second component 200 between the two protrusions 311, thus limiting the rotational displacement of both components when the third component 300 rotates relative to the second component 200. Or, for example, Figure 2 In the example shown, the two sidewalls are provided with protrusions 312 extending toward each other to limit the rotational displacement of the third component 300 relative to the second component 200.
[0098] like Figures 3 to 8As shown, the bottom wall 302 is provided with a first tooth 304, and the second component 200 is provided with a second tooth 217 that is adapted to the first tooth 304. When the third component 300 rotates relative to the second component 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 meshing first tooth 304 and second tooth 217, the tactile feedback during rotation can be increased, and the rotation can be stopped at the angle after rotation.
[0099] The second tooth portion 217 includes multiple teeth, with grooves formed between adjacent teeth. The first tooth portion 304 may include multiple teeth (with grooves formed between adjacent teeth), or it may include a single tooth. The connecting member 300 (third component) is located at... Figure 7 In the position shown, the first tooth 304 and the second tooth 217, located at the lower part of the figure, are engaged. When the connecting member 300 (third component) is located... Figure 8 In the position shown, the teeth of the first tooth 304 and the second tooth 217 located at the top of the figure are engaged. That is, when the connecting member 300 (the third component) rotates relative to the second component 200, different teeth in the first tooth 304 and the second tooth 217 are engaged.
[0100] Optionally, in one example, the first tooth 304 and the second tooth 217 may be elastic, such that when the first tooth 304 moves relative to the second tooth 217, the first tooth 304 and the second tooth 217 elastically deform, allowing the first tooth 304 to engage in different tooth slots. Without external force, the connecting member 300 (the third component) and the second component 200 remain in this position.
[0101] 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 the recess of the second component 200, so as to save space.
[0102] Continue to combine Figure 5 The bottom wall 302 has a protruding post 310 located within a frame structure. The second component 200 is located within the frame structure, and the protruding post 310 passes through the second component 200. In this embodiment, the protruding post 310 can replace the second rotating shaft 305 to form a rotating shaft. The protruding post 310 is fixed relative to the third component 300. The second component 200 is sleeved on the protruding post 310 and can rotate around the protruding post 310, so that the third component 300 is rotatably connected to the second component 200 through the protruding post 310. The protruding post 310 may have a central hole, and the pin 305 is installed in the central hole of the protruding post 310. A butterfly-shaped spring 306 presses against the head of the protruding post 310 (second rotating shaft) and the pin 305. In this way, the entire pin 305, including its head, is contained within the frame of the third component 300, which can improve the aesthetics of the product, protect the pin and accessories, and extend the service life.
[0103] like Figure 3 , Figure 4 and Figure 6 As shown, the end of the protrusion 310 is an elongated cylinder, the hole on the second component 200 corresponding to the end of the protrusion 310 is a round hole, and the center hole on the protrusion 310 of the third component 300 is a round hole. That is, the shaft pin 305 and the second component 200 remain relatively stationary (both are fixed), and the second component 200 can rotate around the protrusion 310 relative to the third component 300, realizing the function of the third component 300 swinging up and down. In addition, a friction plate 307 can also be sleeved on the protrusion 310 (second rotating shaft), and the friction plate 307 is disposed between the protrusion 310 and the butterfly-shaped spring plate 306.
[0104] The butterfly-shaped spring 306 is elastic and its initial shape is a curved surface (see...). Figure 9 When the pin 305 is assembled into the corresponding hole of the second component 200, the butterfly spring 306 is squeezed and forced to deform into a plane (see...). Figure 10 The corresponding hole between the pin 305 and the second component 200 can be an interference fit to ensure that the pin 305 will not be pushed out by the spring force of the butterfly spring 306. The pin 305 and the second component 200 can also be fixed by riveting or welding, which can also ensure that the pin will not be pushed out by the spring force of the butterfly spring 306. In this case, since the butterfly spring 306 is always compressed, it provides a damping feel during the rotation process.
[0105] Optionally, in one example, when the third component 300 and the second component 200 rotate relative to each other, the first tooth 304 and the second tooth 217 also move relative to each other. When the highest points of the two teeth contact each other, the second component 200 is forced to move slightly outward (away from the bottom wall 302) along the axial direction of the protrusion 310, and when the lowest points of the two teeth contact each other, the second component 200 moves slightly inward (closer to the bottom wall 302) along the axial direction of the protrusion 310. Since the second component 200 is fitted with a butterfly-shaped spring 306, when the third component 300 rotates relative to the second component 200, the first tooth 304 and the second tooth 217 can elastically contact each other under the deformation of the butterfly-shaped spring 306.
[0106] The engagement of pin 305 and butterfly spring 306 forms a damping shaft. The damping shaft provides a stepless damping feel. The engagement of the first tooth 304 and the second tooth 217 provides a stepped damping feel. The damping shaft and the tooth can be provided simultaneously, or only the tooth can be provided without the damping shaft, or only the damping shaft can be provided without the tooth. Example 2
[0107] like Figures 11 to 18As shown, the difference between Embodiment 2 and Embodiment 1 is that the second rotating shaft (pin 305) passes through the third component 300 from the outside and connects to the second component 200. In Embodiment 1, the second rotating shaft (protrusion 310) passes through the second component 200 and the third component 300 from the inside. The structure of the other parts of Embodiment 2 is basically the same as that of Embodiment 1, and will not be described again here.
[0108] The end of the pin 305 is an elongated cylinder, and the corresponding holes on the second component 200 are matching elongated holes. The center hole on the protrusion 310 of the third component 300 is a round hole. That is, the pin 305 and the second component 200 remain relatively stationary (both are fixed), while the third component 300 can rotate around the pin 305 relative to the second component 200, realizing the function of the third component 300 swinging up and down. In addition, a friction plate 307 can also be sleeved on the pin 305, and the friction plate 307 is located between the pin 305 and the butterfly spring 306.
[0109] In this embodiment, the pin 305 can be a second rotating shaft 305. The pin 305 can pass through the third component 300 and the second component 200 and be fixed to the second component 200, so that the third component 300 forms a rotatable connection with the second component 200 around the pin 305, and the third component 300 can rotate relative to the second component 200 around the second rotating shaft 305.
[0110] This disclosure also provides a rotating shaft mechanism, for example... Figures 19 to 41As shown, the first component and the second component are assembled together via a first rotating shaft 201 to form a rotating shaft mechanism. The rotating shaft mechanism may include a first rotating shaft 201, a first component 100, a second component 200, and a mating portion 102; the first component 100 has a first abutting portion 101. The second component 200 has a second abutting portion 202; the second component 200 is rotatably connected to the first component 100 via the first rotating shaft 201, and the second component 200 is rotatable relative to the first component 100 within a preset angle range, and the second component 200 has a first position and a second position. Optionally, either 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, and a first included angle α is formed between them. When the mating portion 102 is formed on the second component 200, the mating portion 102 engages with the second abutting portion 202, and a second included angle β is formed between them. Optionally, the first included angle α and the second included angle β define the range of rotation angles of the second component 200 relative to the first component 100. That is, when the mating part 102 is formed on the first component 100, the preset angle range is 0 to 180º-α; when the mating part 102 is formed on the second component 200, the preset angle range is 0 to 180º-β. The values of α and β can be determined according to the actual application field and product of the rotating shaft mechanism, as well as the actual required rotation angle. In addition, α and β can be equal or unequal.
[0111] For example, the mating part 102 can connect with the first abutting part 101 (or the second abutting part 202). This connection can occur if the mating part 102 and the first abutting part 101 (or the second abutting part 202) are disposed on the same component and extend continuously, or if they are disposed on different components and extend continuously. It is understood that there can also be a gap between the mating part 102 and the first abutting part 101 (or the second abutting part 202).
[0112] For example, a pivot mechanism can be applied to eyeglasses. The temples 405 of the eyeglasses are connected to a second component 200, and the frame 404 is connected to a first component 100. The second component 200 can drive the temples 405 to rotate relative to the first component 100 and the frame 404, thereby opening the temples 405 outwards. This allows the eyeglasses to fit different head circumferences and is convenient to wear. For example, when the temples 405 need to open outwards by 10º to 15º, the first angle and the second angle can be set to 165º to 170º respectively.
[0113] It is understood that the hinge mechanism of this disclosure embodiment can be applied to eyeglasses alone, allowing the temples of the eyeglasses to expand further outward after being unfolded. The hinge mechanism of this disclosure embodiment can also be used together with the third component in the above embodiments to form a connecting mechanism for eyeglasses, allowing the temples of the eyeglasses to not only expand further outward after being unfolded, but also to swing up and down.
[0114] In one example, this disclosure provides eyeglasses that may include a frame and temples for housing lenses. The frame itself may serve as a first component, and a second component is rotatably connected to the frame via a pivot. The temples are connected to the frame via the second component. The frame has a first plane located on its inner sidewall and an inclined plane forming an angle with the first plane. The second component has a second plane, which includes a first portion corresponding to the first plane and a second portion corresponding to the inclined plane. The second component can rotate relative to the frame between a first position and a second position via the pivot. In the first position, the first plane is in contact with the first portion of the second plane, and in the second position, the inclined plane is in contact with the second portion of the second plane.
[0115] When the mating part 102 is formed on the first component 100 and the second component 200 is in the first position, the first abutting part 101 interacts with the second abutting part 202 to hold the second component 200 in the first position. When the mating part 102 is formed on the first component 100 and the second component 200 is in the second position, the mating part 102 interacts with the second abutting part 202 to hold the second component 200 in the second position. When the mating part 102 is formed on the second component 200 and the second component 200 is in the first position, the first abutting part 101 interacts with the second abutting part 202 to hold the second component 200 in the first position. When the mating part 102 is formed on the second component 200 and the second component 200 is in the second position, the first abutting part 101 interacts with the mating part 102 to hold the second component 200 in the second position.
[0116] The rotating shaft mechanism of this application embodiment provides mating parts on the first component 100 and the second component 200, and abutting parts on the first component 100 and the second component 200 respectively, so that the second component 200 can rotate relative to the first component 100. During rotation, the action between the mating part and the abutting part and the action between the abutting parts can be switched, so that the second component 200 can be maintained in the first position or the second position after rotation, thereby realizing the adjustment of the angle between the first component 100 and the second component 200.
[0117] Optionally, inclined surfaces can be provided on the first component 100 and the second component 200, and flat surfaces can be provided on the first component 100 and the second component 200 respectively, so that the second component 200 can rotate relative to the first component 100, and during rotation, the interaction between the inclined surface and the flat surface (e.g., the inclined surface and the flat surface are in contact) and the interaction between the flat surfaces (e.g., the flat surface and the flat surface are in contact) can switch. It is understood that the terms "flat surface" and "inclined surface" mentioned above can both have substantially flat surfaces, and "inclined surface" is named because it is at a certain angle relative to the term "flat surface". Optionally, the mating part can also be a structure with curved surfaces, concave parts, or protrusions, etc., and the abutting part can also be a structure with curved surfaces, concave parts, or protrusions, etc.
[0118] In one example, the first abutment is a first plane, the second abutment is a second plane, and the mating parts can be configured in one of the following arrangements: The first component includes a mating part, which is an inclined plane forming a first angle with respect to the first plane. When the second component is in a first position, the first plane and the second plane are in contact; when the second component is in a second position, the inclined plane and the second plane are in contact. Alternatively, the second component includes a mating part, which is an inclined plane forming a second angle with respect to the second plane. When the second component is in the first position, the first plane and the second plane are in contact; when the second component is in the second position, the inclined plane and the first plane are in contact.
[0119] Optionally, the first abutting portion, the second abutting portion, and the mating portion may be located between the first component and the second component and are covered by the first component and / or the second component so that they are not easily observed from the outside.
[0120] In some embodiments, the rotating shaft mechanism may further include an elastic element disposed between the first component 100 and the second component 200, for providing a reset force to the second component 200 to rotate from the second position toward the first position, so that the second component 200 can be reset from the second position to the first position when no external force is applied.
[0121] This application does not specifically limit the specific structure, location, or mode of operation of the elastic element, as long as it can provide a restoring force to the second component 200 for rotation from the second position toward the first position. In one example, the elastic element can be an elastic body that can deform along an axial direction perpendicular to the first axis of rotation 201 to provide a restoring force to the second component 200 for rotation from the second position toward the first position, for example, providing the aforementioned restoring force in a direction substantially perpendicular to the axial direction of the first axis of rotation 201.
[0122] For example, in the embodiment where the aforementioned pivot mechanism is applied to eyeglasses, when no external force is applied to the eyeglasses, the second component 200 is in the first position, and the temples 405 of the eyeglasses can be understood as being in an unextended state. To ensure that the temples 405 can be stably maintained in the first position, the elastic element can have a certain deformation so that a certain force can be applied to the second component 200. When an external force is applied to the eyeglasses, causing the temples 405 to extend outward, the relative distance between the two temples 405 increases to accommodate different users' head circumferences. As the temples 405 extend outward, the second component 200 rotates relative to the first component 100 around the first pivot 201. The second component 200 causes the elastic element to continue to deform until the second component 200 rotates to the second position. Because the mating part 102 interacts with the first abutment part 101 or the second abutment part 202, the second component 200 is restricted to the second position and cannot continue to rotate. The deformation of the elastic element reaches its maximum, and the temples 405 extend outward to their maximum extent. After the second component 200 leaves the first position, whether it is in a position between the first and second positions or in the second position, the elastic element can apply force to the second component 200 under the action of deformation, so that the second component 200 can be reset from the second position to the first position when no external force is applied.
[0123] Although the above example of eyeglasses illustrates the changes in the elastic element during the rotation of the second component 200, it is understood that the same principle applies when the above-mentioned rotating shaft mechanism is used in other devices.
[0124] The specific structure of the rotating shaft mechanism of this application will be described below with reference to different embodiments. It should be noted that, for the sake of convenience, the rotation of the second component 200 from the first position to the second position is referred to as outward expansion, and the rotation of the second component 200 from the second position to the first position is referred to as resetting. In addition, "upper," "lower," "left," and "right" refer to the positions shown in the accompanying drawings. Example 1
[0125] like Figures 19 to 21 As shown, in Embodiment 1, the mating part 102 is formed on the first component 100. One end of the elastic member abuts against the portion of the second component 200 that interacts with the first abutting part 101 of the first component 100, and the other end abuts against the portion of the first component 100 opposite to the first abutting part 101. The first rotating shaft 201 is close to the mating part 102 relative to the elastic member.
[0126] Continue to combine Figures 19 to 21The elastic element includes a compression spring 210, which is extendable and retractable in a direction substantially perpendicular to the axial direction of the first rotating shaft 201. It is understood that other types of elastic elements different from the compression spring 210 may also be used in this embodiment. The second component 200 includes a pivot portion 203, a second abutment portion 202 located on a first side of the pivot portion 203, and a spring seat 204 provided on a second side of the pivot portion 203 corresponding to the portion of the first abutment portion 101 of the first component 100. One end of the compression spring 210 is positioned in the spring seat 204. The portion of the second side of the pivot portion 203 corresponding to the mating portion 102 of the first component 100 includes a bearing seat 205, through which the first rotating shaft 201 passes.
[0127] For example, Figure 20 and Figure 21 The first component 100 has an outer sidewall, a front sidewall, and an inner sidewall defining a cavity. The upper part of the left sidewall 301 (i.e., the outer sidewall) of the cavity forms a first abutment portion 101, and the lower part of the left sidewall 301 slopes outward to form a mating portion 102. In this example, the first abutment portion 101 can be a plane, and the mating portion 102 can be an inclined plane. The upper part of the second component 200 forms a pivot portion 203. The left side of the pivot portion 203 (closer to the left sidewall 301, or the side facing the left sidewall 301) is the first side, and a second abutment portion 202 is formed therein. The second abutment portion 202 corresponds to both the first abutment portion 101 and the mating portion 102. In this example, the second abutment portion 202 can be a plane. The second side of the pivot portion 203 is opposite to the first abutment portion 101 and can be referred to as the right side. The upper right side of the pivot portion 203 is recessed to form a recess, and a spring seat 204 is disposed in the recess. In this embodiment, the spring seat 204 can be a protruding post, and one end of the compression spring 210 can be sleeved on the protruding post. The lower right side of the pivot portion 203 (the part away from the front sidewall) forms a protrusion relative to its upper part, and the protrusion serves as the bearing seat 205 of the first rotating shaft 201, through which the first rotating shaft 201 passes. This allows the first rotating shaft 201 to be close to the mating portion 102 relative to the compression spring 210 (elastic element), facilitating the compression spring 210 to apply force and provide a restoring force for the second component 200 to rotate from the second position toward the first position.
[0128] Compression springs 210 can be arranged in multiple parallel configurations, such as two, to provide a stable and balanced restoring force for the second component 200.
[0129] like Figure 20As shown, when the second component 200 is in the first position, the compression spring 210 applies a force to the second component 200, causing it to abut against the first component 100. The second abutting portion 202 of the second component 200 is in contact with the first abutting portion 101 of the first component 100 and can remain in the first position. When a force is applied to the second component 200 to extend it outward to the left (outward) as shown in the figure, the second component 200 rotates until its second abutting portion 202 is in contact with the mating portion 102 on the first component 100. See [reference needed]. Figure 21 The compression spring 210 remains compressed and applies a force to the second component 200, causing it to tend to return from the second position to the first position. Example 2
[0130] like Figures 22 to 30 As shown, the mating part 102 is formed on the second component 200. The elastic element includes elastic posts located on opposite sides of the first rotating shaft 201, each passing through the second component 200. When the second component 200 switches from the first position to the second position, the elastic posts on different sides of the first rotating shaft 201 elastically deform in opposite directions. The elastic posts, which elastically deform in opposite directions, provide a restoring force to the second component 200 to rotate from the second position toward the first position.
[0131] For example, such as Figure 24 and Figure 25 As shown, the second component 200 includes a first protrusion 206 located on its first side and a second protrusion 207 located on its second side. The elastic post includes a first elastic post 211 and a second elastic post 212. The first elastic post 211 passes through the first protrusion 206 and is fixed at both ends to the first component 100. The second elastic post 212 passes through the second protrusion 207 and is fixed at both ends to the first component 100.
[0132] Continue to combine Figure 24 and Figure 25 The first component 100 includes a first ear plate 103 and a second ear plate 104 arranged vertically opposite each other. A first rotating shaft 201 passes through the second component 200 and is connected to the two ear plates at both ends. The two ends of the two elastic pillars are fixed to the two ear plates respectively.
[0133] like Figure 22 As shown, the first component 100 also includes an end plate 105, with two ear plates disposed on the surface of the end plate 105, forming a first abutment portion 101. One end of the second component 200 faces the end plate surface and forms a second abutment portion 202. The first rotating shaft 201 is parallel to the first abutment portion 101 and the second abutment portion 202. In the non-deformation state (when the second component 200 is in the first position), both the first elastic post 211 and the second elastic post 212 are parallel to the first rotating shaft 201.
[0134] like Figures 26 to 28 As shown, when the second component 200 is... Figure 26 and Figure 27 The first position Figure 28 The second position rotates, that is, the second component 200 rotates towards... Figure 26 and Figure 28 When the left side (outward) is rotated as shown, the first protrusion 206 and the second protrusion 207 of the second component 200 respectively cause the elastic column passing through it to undergo elastic deformation. Figure 26 and Figure 28 The first protrusion 206 located on the left (outer side) drives the first elastic column 211 located on the left to elastically deform towards the upper part shown in the figure (when the pivot mechanism is applied to smart glasses, the first elastic column 211 moves towards the front frame of the glasses). Figure 26 and Figure 28 The second protrusion 207 located on the right (inner side) drives the second elastic column 212 located on the right to elastically deform towards the lower part shown in the figure (when the pivot mechanism is applied to smart glasses, the first elastic column 211 moves away from the front frame). Because the elastic column has the characteristic of restoring its deformation after deformation, it achieves the rebound force when the second component 200 is stretched outward. Example 3
[0135] like Figures 31 to 33 As shown, the mating part 102 is formed in the second component 200. The first component 100 and the second component 200 define the receiving part 106. The elastic member is an elastic pad 213, which is disposed in the receiving part 106 and simultaneously abuts against the first component 100 and the second component 200. When the second component 200 rotates from the first position to the second position, that is, when it expands outward to the left in the figure to the second position, the second component 200 compresses the elastic pad 213, causing it to undergo elastic deformation (see Figure 100). Figure 33 The elastic pad 213 accumulates elastic potential energy to generate a rebound force, which provides a restoring force to the second component 200 to rotate from the second position to the first position. That is, the force that restores the second component 200 from the second position to the first position can be obtained by the rebound force of the elastic pad 213.
[0136] Continue to combine Figure 31The first component 100 has a cavity, and one end of the second component 200 extends into the cavity, forming a receiving portion 106 between it and the left side wall 301 (outer side wall) of the cavity. The end face of the second component 200 extending into the cavity forms a second abutment portion 202. A first abutment portion 101 and a mating portion 102 are formed on the surface of the first component 100 opposite to the second abutment portion 202. That is, the bottom of the cavity forms the first abutment portion 101 and the mating portion 102. A first side of the elastic pad 213 is attached to a side of the second component 200 located within the receiving portion 106, and a second side of the elastic pad 213 is attached to the side wall 301 of the cavity opposite to the side wall of the second component 200. To fix the elastic pad 213, it can be adhered to the side wall 301 of the cavity. Example 4
[0137] like Figures 34 to 36 As shown, the difference between Embodiment 4 and Embodiment 3 is only that the elastic pad 213 is replaced with a spring sheet 214. The spring sheet 214 is disposed in the receiving portion 106. When the second component 200 is in the second position, the spring sheet 214 deforms to provide a reset force to the second component 200 to rotate from the second position toward the first position.
[0138] In Embodiment 4, the outward elasticity of the second component 200 can be achieved by the spring sheet 214. The spring sheet 214 can be fixed to the side wall 301 of the receiving portion 106 of the first component 100 by pasting or welding. When the second component 200 rotates outward, it compresses the spring sheet 214 to obtain the elasticity. Example 5
[0139] like Figures 37 to 39 As shown, the elastic element includes a spring sheet assembly 215 formed by stacking multiple spring sheets in sequence; the spring sheet assembly 215 acts on the end face of the second component 200 adjacent to the second abutment portion 202. When the second component 200 is in the second position, the spring sheet assembly 215 deforms to provide a restoring force to the second component 200 to rotate from the second position toward the first position.
[0140] Continue to combine Figures 37 to 39The first component 100 has a cavity, with a first abutment portion 101 formed on the upper part of the left side wall 301 of the cavity, and an outwardly inclined mating portion 102 formed on the lower part of the left side wall 301 of the cavity. The first end of the second component 200 extends into the cavity, and a spring sheet assembly 215 is located between the first end of the second component 200 and the upper side wall 301 of the cavity. Multiple spring sheets are stacked sequentially from top to bottom. The side of the first end of the second component 200 closest to the left side wall 301 of the cavity protrudes from the side furthest from the left side wall 301 of the cavity, forming a protrusion. The spring sheet assembly 215 acts on the end face of the protrusion. The first rotating shaft 201 is located below the protrusion and as far away from the left side wall 301 of the cavity as possible, so that the spring sheet assembly 215 can provide a force to the second component 200 to reset it from the second position to the first position. In order to allow space for deformation of the spring assembly 215, the top sidewall of the cavity is recessed to allow the free end of the spring assembly 215 (acting on the protruding end face) to deform. The top sidewall of the cavity is also provided with a mounting part to fix the fixed end of the spring assembly.
[0141] The first component 100 in the above embodiments may include a first component body and a rotating shaft connector. The rotating shaft connector and the first component body may be an integral part. Alternatively, the rotating shaft connector is connected to the first component body. A first abutment portion 101 is formed on the rotating shaft connector, and the second component 200 is rotatably connected to the rotating shaft connector via a first rotating shaft 201.
[0142] All the elastic elements in the above embodiments can provide preload, making the second component 200 less prone to rotation. It should be noted that, in Embodiment 2, if the elastic column is to provide preload, the upper, middle, and lower points of the elastic column are not collinear. That is, the holes and protrusions of the first ear plate 103 and the second ear plate 104 that fix the elastic column are not coaxial and pass through the holes of the elastic column in order to provide preload in advance.
[0143] like Figures 40 to 59 As shown, this application embodiment also provides a pair of eyeglasses 400. The eyeglasses 400 includes a frame 404 and temples 405, and further includes a pivot mechanism as described in any of the above embodiments; or the eyeglasses 400 further includes a connecting mechanism 420 for eyeglasses as described in any of the above embodiments. The frame 404 and temples 405 are connected via the pivot mechanism or the connecting mechanism 420.
[0144] When the eyeglasses 400 include a hinge mechanism, there are two sets of hinge mechanisms. The first components 100 of the two sets of hinge mechanisms are fixed to the frame 404, and the two temples 405 are hinged to the second components 200 of the two sets of hinge mechanisms. Since 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 bent outwards, thereby adjusting the distance between the two temples 405 to accommodate different wearers' head circumferences. In addition, the hinges between the temples 405 and the second component 200 allow the temples 405 to be folded for easy storage.
[0145] When the eyeglasses 400 includes a connecting mechanism 420, there are two sets of connecting mechanisms 420. The first components 100 of the two sets of connecting mechanisms 420 are respectively fixed to the frame 404, and the two temples 405 are respectively hinged to the third components 300 of the two sets of connecting mechanisms 420. Since the second component 200 can rotate left and right relative to the first component 100, the two temples 405 can be bent outwards, thereby adjusting the distance between the two temples 405 to accommodate different wearers' head circumferences. Since the third component 300 can rotate up and down relative to the second component 200, the two temples 405 can be adjusted up and down to accommodate different wearers' ear heights. In addition, the temples 405 are hinged to the third component 300, allowing the temples 405 to be folded for easy storage. The eyeglasses 400 of this embodiment are highly adaptable, easy to wear, and provide a good user experience.
[0146] like Figure 41 As shown, the frame 404 of the eyeglasses 400 and the first component 100 can be separate structures. The frame 404 may have fixing holes 406, and the first component 100 can be fixed to the frame 404 using screws 407 or other connecting parts. Alternatively, the frame 404 can be directly used as the first component 100; or the frame 404 can be part of the first component 100; or the frame 404 and the first component 100 can be a single piece. The frame 404 can be made of plastic materials such as ABS or PC. To ensure wear and fatigue resistance during rotation, the first component 100 can be made of aluminum alloy, stainless steel, or polyoxymethylene (POM). When the frame 404 and the first component 100 are a single piece, both can be made of metal and directly molded as a single unit, facilitating assembly.
[0147] like Figure 40 As shown, glasses 400 are smart glasses, and the smart glasses also include an optical imaging system 401. (As...) Figure 60 As shown, the optical imaging system 401 includes an image source component 402 and an optical component 403. The smart glasses can be head-mounted display devices such as AR glasses and VR glasses. The image source component 402 is used to display the image projected onto the viewer's eye, while the optical component 403 functions to change the light path, among other things.
[0148] The connection method between the temple 405 and the third component 300, as well as the routing method of the data cable 408, will be described below with reference to different embodiments. Example 1
[0149] When the glasses 400 are smart glasses, the frame 404 (display body) and temples 405 are typically connected by a data cable 408. For example... Figure 42 and Figure 43 As shown, the data cable 408 extends from the display body, passes through the third component 300, and extends to the temple 405. Figure 43 , Figure 45 and Figure 46 As shown, the eyeglasses 400 also includes a folding hinge 409 and a hinge fixing seat 410. The hinge fixing seat 410 is fixed to the inside of the temple 405. For easy disassembly, the hinge fixing seat 410 can be snapped onto the temple 405 and secured by a buckle. One end of the folding hinge 409 is rotatably connected to the third component 300, and the other end is fixed to the hinge fixing seat 410, allowing the temple 405 to rotate relative to the third component 300. The temple 405 is hinged to the third component 300 through the folding hinge 409, allowing the temple 405 to fold and unfold. When folded, the temple 405 is easy to store and carry.
[0150] Continue to combine Figure 46 The folding hinge 409 includes a hinge portion 411 and a third pivot 412. The hinge portion 411 has a through hole 413 and a cutout 414 that passes through both ends of its axial direction and communicates with the through hole 413 (see [link]). Figure 49 The third pivot 412 passes through the through hole 413 and is tightly fitted to the through hole 413 to provide rotational damping for the folding hinge 409.
[0151] See also Figure 45 and Figure 46 The portion of the data cable 408 extending into the temple 405 can be fixed within the temple 405 via a hinge fixing seat 410. That is, the data cable 408 is positioned between the temple 405 and the hinge fixing seat 410. In this embodiment, two hinge fixing seats 410 can be arranged side-by-side. The folding hinge 409 is assembled and fixed to the two hinge fixing seats 410 respectively by two screws to prevent the folding hinge 409 from twisting and improve stability.
[0152] like Figure 47 and Figure 48As shown, the eyeglasses 400 also includes a connector cover plate 415 and a temple cover plate 416. The connector cover plate 415 covers the third component 300 and is used to cover the data cable 408 passing through the third component 300. The temple cover plate 416 covers the temple 405 and is used to cover the data cable 408 inside the temple 405. The cover plates can be fixed to the third component 300 or the temple 405 by adhesive or snap-fit. The connector cover plate 415 and the temple cover plate 416 are flexibly connected at opposite ends so that they can rotate relative to each other. As the temple 405 folds, the connector cover plate and the temple cover plate 416 also bend at the connection point, so as not to hinder the folding of the temple 405. The so-called flexible connection is relative to the rigid connection. The flexible connection can rotate at the connection point. For example, the connection is achieved by the component that can undergo elastic or flexible deformation, such as the connection by silicone, rubber, flexible strip, etc. Of course, the connecting cover plate 415 and the temple cover plate 416 can also be rotatably connected to facilitate rotation when the temple 405 is bent, without affecting the bending of the temple 405. Alternatively, the connecting cover plate 415 and the temple cover plate 416 can be clearance-fitted, so that when the temple 405 switches between folded and unfolded states, the opposite ends of the connecting cover plate 415 and the temple cover plate 416 will not interfere with each other, thus not affecting the unfolding and folding of the temple 405. The unfolded and folded states of the temple 405 can be found in [reference needed]. Figure 49 and Figure 50 . Example 2
[0153] like Figure 51 and Figure 52 As shown, the third component 300 of the temple 405 achieves a rotatable connection through the cooperation of the pin 417 and the retaining ring 418. For example, continuing the combination Figure 51 The third component 300 and the temple 405 are frame-shaped structures that fit each other at opposite ends. The end of the temple 405 covers the end of the third component 300. The upper sidewall 301 of the temple 405 and the upper sidewall 301 of the third component 300 are respectively provided with corresponding upper mounting holes. The lower sidewall 301 of the temple 405 and the lower sidewall 301 of the third component 300 are respectively provided with corresponding lower mounting holes. There can be two pins 417, which are respectively installed in the upper mounting hole and the lower mounting hole. A retaining spring 418 is provided on the part of the pin 417 that protrudes from the mounting hole to limit the pin 417 to be contained within the mounting hole.
[0154] Pin 417 can be tightly fitted with the mounting hole to provide rotational damping, see [link / reference]. Figure 54 Alternatively, a washer 419 may be provided between the pin 417 and the mounting hole; that is, the portion of the pin 417 located within the mounting hole is fitted with a washer 419 to provide rotational damping. See [link to relevant documentation]. Figure 55 Of course, pin 417 can be replaced by other shaft-like components, and is not limited to pin 417.
[0155] like Figure 53 As shown, after the temple 405 and the third component 300 are hinged, the data cable 408 extends from the frame 404 through the third component 300 to the temple 405. Figure 56 and Figure 57 As shown, the glasses 400 also includes a connector cover plate 415 and a temple cover plate 416. The cover plates can position the data cable 408 within the third component 300 and the temple 405. The connection method and mating method of the connector cover plate 415 and the temple cover plate 416 can be the same as in Embodiment 1, and will not be described again here.
[0156] like Figure 58 and Figure 59 As shown, the temple 405 can be unfolded and folded relative to the third component 300, making it easy to store and carry after folding.
[0157] The glasses 400 of this embodiment can open outwards, swing up and down, and fold, improving the user experience. The outward opening and rebound function is achieved through elastic pillars, compression springs 210, elastic pads 213, spring sheets, and spring sheet groups 215. A butterfly-shaped spring sheet 306 provides swing damping, making wearing more comfortable. Through a reasonable structural arrangement, the data cable 408 passes through the interior, and the overall structure is sealed.
[0158] The above description is intended to be illustrative and not restrictive. Those skilled in the art can make variations, modifications, substitutions, and alterations to the above embodiments within the scope of this disclosure. Furthermore, the above examples (or one or more thereof) can be used in combination with each other, and these embodiments can be combined with each other in various combinations or arrangements. The scope of this application should be determined by referring to the appended claims and the full scope of their equivalents.
