[0013] The present application is further described in detail below in conjunction with the accompanying drawings and examples. It is particularly noted that the following examples are only used to illustrate the present application, but are not intended to limit the scope of the present application. Similarly, the following examples are only some embodiments of the present application rather than all embodiments, and all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0014] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0015] See also Figure 1 , Figure 1 It is a schematic diagram of the structure of the glasses 10 provided in an embodiment of the present application.

[0016] The glasses 10 provided in the embodiment of the present application may be smart glasses with functions such as video recording, lighting or display, or may be ordinary glasses with functions such as vision correction, shading, decoration or anti-glare. Figure 1 As shown, the glasses 10 may include: a lens 100 and a wearing bracket 200. The lens 100 is disposed on the wearing bracket 200, and the wearing bracket 200 can be worn on the user's head. At the same time, the lens 100 can be located in front of the user's eyes, and the wearing bracket 200 can be supported on the user's nose and ears. In addition, the structure of the wearing bracket 200 supporting the user's nose can also be adjusted, so that different wearers can adjust the wearing bracket 200 according to their own needs, so as to improve the versatility of the glasses 10 between different wearers.

[0017] Exemplarily, the lens 100 can also be used to conduct light and can form an image in front of the user's eyes to achieve the function of augmented reality. For example, the lens 100 can be an optical waveguide sheet, specifically a planar grating waveguide sheet (such as a diffraction grating waveguide sheet), and the glasses 10 can also include an optical machine 300 disposed on the wearing bracket 200, and the lens 100 can conduct the light emitted by the optical machine 300 for imaging to achieve the function of augmented reality in front of the user's eyes. Among them, the lens 100 can be provided with an optical coupling inlet portion arranged opposite to the optical machine 300 in the light emitting direction of the optical machine 300, and an optical coupling outlet portion connected to the optical coupling inlet portion and located in front of the user's eyes. At the same time, the optical coupling inlet portion and the optical coupling outlet portion are connected together to form an optical path, and the light can be coupled into the lens 100 from the optical coupling inlet portion, and after being transmitted in the optical path, it is coupled out of the lens 100 from the optical coupling outlet portion to be shot into the wearer's eyes, so that the wearer can see the corresponding virtual image. In addition, the optical coupling outlet is also light-transmissive, and external light can pass through the optical coupling outlet into the wearer's eyes, so that the wearer can see the real external environment and the virtual image displayed by the optical coupling outlet at the same time, thereby realizing the function of augmented reality.

[0018] Optionally, in addition to realizing image display through the cooperation of the optical machine 300 and the lens 100 (optical waveguide), the lens 100 can also be a display screen with a display function to provide the glasses 10 with an image display function. Among them, when the lens 100 is a display, the lens 100 can still have light transmittance (such as a transparent display screen), and the opaque structure in the lens 100 (such as metal wiring, etc.) can be arranged in the partial area of ​​the lens 100 blocked by the wearing bracket 200, so that the user can still see the real environment outside through the lens 100, and can be combined with the virtual image displayed by the lens 100 to realize the function of augmented reality. Of course, in some embodiments, the lens 100 can also be used to realize the function of virtual reality, in which case the lens 100 may not have light transmittance to reduce the interference of external light on the virtual image displayed by the lens 100.

[0019] Optionally, when the glasses 10 are used to achieve other functions besides displaying images, the lens 100 may also be a vision correction lens made of one or more lenses such as convex lenses and concave lenses, and other types of lenses or functional lenses (such as flat lenses, anti-glare lenses, colored lenses, etc.) or functional films (such as anti-reflection films, polarizing films, filter films, etc.) may also be provided in the vision correction lens. Of course, the lens 100 may also be other functional lenses such as flat lenses, anti-glare lenses, colored lenses, and decorative lenses.

[0020] Optionally, the lens 100 may also be a photochromic device. For example, the photochromic device may be made of a photochromic material so that the photochromic device can change color after being excited by light of a certain wavelength. The photochromic material may be made using a technical solution already existing in the prior art within the scope of understanding of those skilled in the art, and no further description is given. Alternatively, the lens 100 may also be an electrochromic device. For example, the electrochromic device may be made of an electrochromic material. The electrochromic material may be one of an inorganic electrochromic material and an organic electrochromic material. The inorganic electrochromic material may be tungsten trioxide. The organic electrochromic material may be one of polythiophenes and their derivatives, viologens, tetrathiafulvalene, metal phthalocyanine compounds, and the like. Of course, the electrochromic material may be made using a technical solution already existing in the prior art within the scope of understanding of those skilled in the art, and no further description is given.

[0021] Optionally, the number of lenses 100 can be two, and the two lenses 100 can be respectively arranged at the positions of the wearing bracket 200 corresponding to the left and right eyes of the user, and can be symmetrically arranged on the wearing bracket 200. Among them, both lenses 100 can be optical waveguides, and the number of optical machines 300 can also be two, and the two optical machines 300 can be respectively arranged corresponding to the two lenses 100. Of course, in some embodiments, only one of the two lenses 100 can be an optical waveguide, and the other can be the aforementioned ordinary functional lens, such as an anti-glare lens, a tinted lens, and a myopia lens. Or, when the glasses 10 do not need to realize the function of image display, the two lenses 100 can also be the aforementioned ordinary functional lenses. That is, the specific type of the lens 100 can be selected according to the required function of the glasses 10, and this embodiment does not limit this.

[0022] For example, the wearing bracket 200 can be used to install the lens 100 and can be worn on the user's head. Figure 1As shown, the wearing bracket 200 may include: a frame 210, a leg 220 and a nose pad 230. Among them, the frame 210 can be arranged relative to the eye area of ​​the wearer, and the frame 210 is provided with through grooves in the areas corresponding to the left and right eyes of the wearer, and the lens 100 can be installed by using the through grooves to fix the lens 100 on the frame 210. The leg 220 is connected to the frame 210 and can be supported on the ear of the user, and the leg 220 can be used to install other functional components required for the glasses 10 in addition to installing the optical machine 300. At the same time, the number of the legs 220 can be two, and the two legs 220 can also be arranged relative and spaced to form a space to avoid the user's head. The nose pad 230 is connected to the frame 210 and can be supported on the user's nose, so that the frame 210 can be worn in front of the user's eyes through the leg 220 and the nose pad 230 to arrange the lens 100 at the position corresponding to the wearer's eyes. In addition, the position of the nose pad 230 can also be adjusted, so that different wearers can adjust the nose pad 230 according to their own needs, so as to improve the versatility of the wearing bracket 200 among different wearers.

[0023] All directional indications (such as up, down, left, right, front, back...) in the embodiments of the present application are only used to explain the relative positional relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication also changes accordingly. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0024] See also Figures 2 to 4 , Figure 2 yes Figure 1 A partial enlarged schematic diagram of point A in the middle. Figure 3 yes Figure 2 The exploded structural diagram of the middle nose pad 230 is shown below. Figure 4 yes Figure 1 Schematic diagram of the partial cross-sectional structure of the wearing bracket 200 along V-V.

[0025] The nose pad 230 is connected to the frame 210 and is located between the two through slots on the frame 210, and the nose pad 230 can be supported on the bridge of the user's nose. Figures 2 to 4As shown, the nose pad 230 may include: a first support rod 231, a second support rod 232 and a support leaf 233. Among them, one end of the first support rod 231 can be inserted into the side of the frame 210 facing the user's eyes, and can rotate with the direction of insertion into the frame 210 as the axis direction X. One end of the second support rod 232 is inserted into the other end of the first support rod 231, and can reciprocate and slide with the direction of insertion into the first support rod 231 as the displacement direction Y, and the axis direction X intersects with the displacement direction Y. The support leaf 233 is connected to the other end of the second support rod 232, and the support leaf 233 can contact the user's nose, so that the frame 210 can be supported on the user's nose through the first support rod 231, the second support rod 232 and the support leaf 233. In this embodiment, by setting the first support rod 231 to be rotatably connected to the frame 210, and the second support rod 232 to be slidably connected to the first support rod 231, and the rotation axis direction X of the first support rod 231 intersects with the displacement direction Y of the second support rod 232, the support leaf 233 can be adjusted in at least two different directions, so that different wearers can adjust the position of the support leaf 233 according to their own needs, thereby improving the versatility of the wearing bracket 200 among different wearers.

[0026] The terms "first", "second", and "third" in this application are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first", "second", and "third" may explicitly or implicitly include at least one of the features.

[0027] Further, the nose pad 230 may be provided with two groups of connected first support rods 231, second support rods 232 and support leaves 233, and the two groups of first support rods 231, second support rods 232 and support leaves 233 may be symmetrically arranged on the frame 210. Wherein, when the user wears the wearing bracket 200 on the head, the two support leaves 233 may be respectively located on opposite sides of the user's nose, and both may contact the user's nose to improve the stability of the nose pad 230 supported on the user's nose. At the same time, when the two first support rods 231 rotate, the two support leaves 233 may move in a direction close to or away from each other with the first support rods 231 to increase or decrease the distance between the two support leaves 233. In addition, when the two second support rods 232 slide, the two support leaves 233 may move in a direction close to or away from the wearer's nose to increase or decrease the distance between the two support leaves 233 and the user's nose. With such a configuration, different wearers can adjust the position of the support leaf 233 according to their own needs, so as to improve the versatility of the wearing bracket 200 among different wearers.

[0028] Optionally, in some embodiments, the nose pad 230 may also only have one set of the first support rod 231, the second support rod 232 and the support leaf 233. The following only takes the connection relationship of a single set of the first support rod 231, the second support rod 232 and the support leaf 233 as an example for explanation.

[0029] For example, a connection hole 211 is provided on one side of the frame 210 close to the user's eyes, and one end of the first support rod 231 can be inserted into the connection hole 211 and can rotate with the direction of insertion into the connection hole 211 as the axis direction X. Figures 2 to 4 As shown, the first support rod 231 may include: a rotating portion 2311, a curved portion 2312 and a sleeve portion 2313. Among them, one end of the rotating portion 2311 can be inserted into the connecting hole 211, and can be rotated with the direction of insertion into the connecting hole 211 as the axial direction X. The curved portion 2312 can be connected to the other opposite end of the rotating portion 2311, and can be bent toward a position close to the user's nose so that the support leaf 233 can contact the user's nose. One end of the sleeve portion 2313 is connected to the other end of the curved portion 2312, and the other opposite end of the sleeve portion 2313 is also provided with a mounting hole 23131. The second support rod 232 is inserted into the mounting hole 23131 from the other opposite end of the sleeve portion 2313, and can slide back and forth with the direction of insertion into the mounting hole 23131 as the displacement direction Y.

[0030] Optionally, in order to realize the rotation suspension of the first support rod 231, the nose pad 230 may further include: an elastic abutment 234, and the elastic abutment 234 may be arranged on one end of the rotating portion 2311 inserted in the connecting hole 211, and can abut against the frame 210 in a direction perpendicular to the axial direction X, so that the first support rod 231 can use the elastic abutment 234 to abut against the frame 210 to limit the rotation of the first support rod 231, thereby realizing the rotation suspension of the first support rod 231. Among them, a groove 2314 is provided on one end of the rotating portion 2311 inserted in the connecting hole 211, and the elastic abutment 234 is arranged in the groove 2314, and a part of the elastic abutment 234 is also protruding from the groove 2314, and can abut against the side wall of the connecting hole 211, that is, the frame 210.

[0031] Optionally, the elastic abutment member 234 may include an elastic portion 2341 and an abutment portion 2342. The elastic portion 2341 is disposed in the groove 2314 and is connected to the groove 2314 and the abutment portion 2342 respectively, and a portion of the abutment portion 2342 is also protruded from the groove 2314. At the same time, the abutment portion 2342 can also abut against the side wall of the connecting hole 211, and can press the elastic portion 2341 together with the bottom wall of the groove 2314 to elastically deform, so as to maintain the abutment state with the side wall of the connecting hole 211 under the elastic force generated by the elastic portion 2341, thereby limiting the rotation of the rotating portion 2311. In addition, the elastic part 2341 may be a spring, and a convex column may be provided on the side of the abutting part 2342 facing the bottom wall of the groove 2314, and one end of the elastic part 2341 may be connected to the bottom wall of the groove 2314, and the other opposite end may be sleeved on the convex column to achieve the connection between the elastic part 2341 and the abutting part 2342. In this embodiment, the abutting part 2342 may be a friction block to increase the friction force generated when the abutting part 2342 rotates with the rotating part 2311, thereby improving the stability of the first support rod 231 when rotating and hovering.

[0032] In some embodiments, the elastic portion 2341 may also be a metal spring sheet, or an elastic pad made of elastic materials such as rubber, silicone or soft plastic. It only needs the elastic portion 2341 to be able to undergo elastic deformation under the pressure of the abutting portion 2342 and the bottom wall of the groove 2314, and this embodiment does not limit this.

[0033] Optionally, in order to further improve the stability of the first support rod 231 in rotation and suspension, a first damping member 235 may be provided on the side wall of the connecting hole 211. Figure 4 As shown, the first damping member 235 can be arranged on the side wall of the connecting hole 211, and is arranged around one end of the rotating portion 2311 inserted into the connecting hole 211, and the first damping member 235 can also abut against the abutment portion 2342 in a direction perpendicular to the axial direction X to increase the friction force generated when the rotating portion 2311 rotates, thereby improving the stability of the first support rod 231 rotating and hovering. In this embodiment, the first damping member 235 can specifically be a silicone ring. Of course, the first damping member 235 is not limited to being made of silicone, and the first damping member 235 can also be made of other materials with a large friction coefficient. It is only necessary that the first damping member 235 can increase the friction force generated when the rotating portion 2311 rotates, and this embodiment does not limit this.

[0034] Optionally, in order to achieve the sliding retention of the second support rod 232, the nose pad 230 may further include: a second damping member 236. Figure 4As shown, the second damping member 236 can be sleeved on one end of the second support rod 232 inserted in the mounting hole 23131, and is located between the second support rod 232 and the side wall of the mounting hole 23131, and the second damping member 236 can also abut against the side wall of the mounting hole 23131 to limit the sliding of the second support rod 232, thereby achieving the sliding retention of the second support rod 232. In this embodiment, the second damping member 236 can also be a silicone ring. Of course, the second damping member 236 is not limited to being made of silicone, and the second damping member 236 can also be made of other materials with a large friction coefficient. It is only necessary that the second damping member 236 can increase the friction force generated when the second support rod 232 slides, and this embodiment does not limit this.

[0035] Optionally, the nose pad 230 can be used on other devices with similar requirements in addition to the glasses 10. For example, the nose pad 230 can also be used on a head-mounted device (VR device) that implements a virtual reality function.

[0036] The nose pad 230 provided by the present application is configured such that one end of the first support rod 231 is inserted into the frame 210 and can rotate with the direction of insertion into the frame 210 as the axis direction X, and one end of the second support rod 232 is inserted into the other end of the first support rod 231 and can slide back and forth with the direction of insertion into the first support rod 231 as the displacement direction Y, and the axis direction X also intersects with the displacement direction Y, so that the support leaf 233 connected to the other end of the second support rod 232 can be adjusted in at least two different directions. With such a configuration, different users can adjust the position of the support leaf 233 by rotating the first support rod 231 and / or sliding the second support rod 232, so that the nose pad 230 can match itself, thereby improving the versatility of the glasses 10 between different users.

[0037] The above descriptions are only some embodiments of the present application, and do not limit the protection scope of the present application. Any equivalent device or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
