[0021] The technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0022] Please see Figures 1 to 6 The smart glasses provided in this application embodiment are, for example, augmented reality (AR) glasses, AI glasses, or functional glasses. In some other embodiments, the smart glasses may also be virtual reality (VR) glasses or other head-mounted display devices with a glasses-like appearance.

[0023] The smart glasses include a frame 10 and a nose pad assembly 20. The frame 10 includes two lens mounting parts 110 for mounting lenses and a nose bridge 120 connected between the two lens mounting parts 110. The nose pad assembly 20 is fixed to the nose bridge 120.

[0024] In some embodiments, the smart glasses also include temples (not shown) that are hinged to the frame 10.

[0025] like Figures 1 to 3 As shown in any of the accompanying drawings, in some embodiments, the nose pad assembly 20 includes a nose pad bracket 210, a first nose pad 220, and a second nose pad 230. The nose pad bracket 210 is fixed to the nose bridge frame 120 or detachably connected to the nose bridge frame 210. At least one of the first nose pad 220 and the second nose pad 230 is movably disposed on the nose pad bracket 210, and the movable first nose pad 220 and / or second nose pad 230 can move longitudinally relative to the nose pad bracket 210 and be limited in position.

[0026] For the nose bridge 210, please refer to... Figure 3 See also Figure 4 and Figure 5 In some embodiments, the nose bridge support 210 includes a connector 2110, a first support 2120, and a second support 2140. The connector 2110 is used to connect to the nose bridge 120. The first support 2120 and the second support 2140 are symmetrically connected to the connector 2110. The end of the first support 2120 away from the connector 2110 is used to connect to the first nose pad 220, and the end of the second support 2140 away from the connector 2110 is used to connect to the second nose pad 230. Exemplarily, the connector 2110 is generally arc-shaped or inverted U-shaped. The nose bridge 120 has a mounting groove 121 that matches the shape of the connector 2110, and the connector 2110 is snapped into the mounting groove 121. Corresponding clearance notches 122 are provided on the mounting groove 121 on the corresponding sides adjacent to the two lens mounting portions 110. The first support 2120 and the second support 2140 extend out of the frame 10 through the corresponding clearance notches 122.

[0027] The first support member 2120 and the second support member 2140 are integrally formed at both ends of the connector 2110. The first support member 2120 and the second support member 2140 are expanded outward and twisted to form an outward octagon shape. In the above technical solution, the nose pad support 210 is an integral structure, which can simplify the complexity of the overall manufacturing process of the nose pad support 210.

[0028] Furthermore, such as Figure 5 As shown, the first support member 2120 is connected to the first adjusting member 2130 at the end away from the connecting member 2110, and the first support member 2120 is connected to the middle position of the first adjusting member 2130 when it is in a longitudinally placed state. The first adjusting member 2130 has multiple first slots 2131, which are arranged at intervals along the longitudinal direction. A first limiting protrusion 2133 is provided between two adjacent first slots 2131. Exemplarily, the first adjusting member 2130 is closed at one end along the longitudinal direction and open at the other end. The multiple first slots 2131 are interconnected to form a first moving path (not shown in the figure). The first moving path forms a first notch 2132 at the open end of the first adjusting member 2130. The first notch 2132 is used for the first support arm 2210 to extend into or disengage. The first limiting protrusions 2133 are arranged in pairs and symmetrically connected to the first adjusting member 2130.

[0029] The second support member 2140 has a second adjusting member 2150 at its end away from the connecting member 2110, and the second support member is connected to the middle position of the second adjusting member when it is in a longitudinally placed state. The second adjusting member 2150 has multiple second slots (not shown in the figure), which are arranged at intervals along the longitudinal direction. A second limiting protrusion (not shown in the figure) is provided between two adjacent second slots. Exemplarily, the second adjusting member 2150 is closed at one end along the longitudinal direction and open at the other end. The multiple second slots are interconnected to form a second moving path (not shown in the figure). The second moving path forms a second notch (not shown in the figure) at the open end of the second adjusting member 2150, which is used for the second support arm 2310 to disengage. The second limiting protrusions are arranged in pairs and symmetrically connected to the first adjusting member 2130.

[0030] In another embodiment of this application, the first support member 2120 is connected to the top or bottom position of the first adjusting member 2130 when it is in a longitudinally placed state; In another embodiment of this application, the first limiting protrusion 2133 is provided on one side of the first adjusting member 2130 and is located between two adjacent first slots 2131; and the second limiting protrusion is provided on one side of the second adjusting member and is located between two adjacent second slots.

[0031] For the first nose pad, 220, please refer to... Figure 6 See also Figure 5In some embodiments, the first nose pad 220 includes a first support arm 2210, which is engaged with any of the first slots 2131 to enable longitudinal movement of the first nose pad 220 relative to the nose pad support 210.

[0032] For example, the first nose pad 220 also includes a first nose flap 2220, which conforms to one side of the user's nose when the user wears the smart glasses. A first support arm 2210 is integrally formed with the first nose flap 2220 and extends outward. The cross-sectional shape of the first support arm 2210 is approximately rectangular. A first annular groove 2211 is provided at the end of the first support arm 2210 away from the first nose flap 2220. A first limiting groove 2212 is provided in the first annular groove 2211 at a position corresponding to the first limiting protrusion 2133. The first limiting groove 2212 is V-shaped or inverted trapezoidal and is used to engage with the first limiting protrusion 2133.

[0033] In this embodiment, due to the hollow design of the first adjusting member 2130, the first adjusting member 2130 has a certain amount of expansion and contraction space in the lateral direction, that is, the first adjusting member 2130 has a certain amount of elasticity in the lateral direction. Therefore, when the first limiting protrusion 2133 is assembled in the first limiting groove 2212, the nose pad can be moved up and down by the action of external force. At the same time, after the external force is released, the first adjusting member 2130 can recover its deformation under the action of elastic restoring force, thereby achieving the limiting and fixing of the nose pad position. Of course, in other embodiments of this application, the first limiting groove 2212 can also be a regular shape such as D-shaped, semi-circular, or trapezoidal.

[0034] In specific implementation, when the first support arm 2210 slides through the first notch 2132 to any of the first slots 2131 within the first moving path, the first nose pad 2220 is restricted from swinging back and forth by the limiting cooperation between the side wall of the first annular groove 2211 and the first adjusting member 2130, and the first nose pad 2220 is restricted from moving up and down by the snap-fit ​​cooperation between the first limiting protrusion 2133 and the first limiting groove 2212, thereby enabling the first nose pad 220 to move longitudinally and be limited relative to the nose pad support 210.

[0035] In the above technical solution, by setting multiple first slots 2131, the position of the first nose pad 220 relative to the nose pad bracket 210 has multiple positions. The first support arm 2210 cooperates with different first slots 2131 to limit the position of the first nose pad 220 relative to the nose pad bracket 210 to different positions. While ensuring that the position of the first nose pad 220 relative to the nose pad bracket 210 is adjustable, the connection between the two is relatively stable after adjustment.

[0036] It is understood that the number of first checkpoints 2131 is not specifically limited in the embodiments of this application. For example, in the embodiments of this application, the number of first checkpoints 2131 is four. In other embodiments, the number of first checkpoints 2131 can be two, three, seven, or other numbers. In other embodiments, the multiple first checkpoints 2131 can be arranged at equal intervals or at unequal intervals.

[0037] It is also understood that in some other embodiments, the first adjusting member 2130 is closed at both ends along the longitudinal direction, and multiple first slots 2131 are arranged at intervals along the longitudinal direction and are not connected to each other. The first support arm 2210 can be inserted or removed from any of the first slots 2131, and the first support arm 2210 can be moved up and down to realize the longitudinal movement of the first nose pad 220 relative to the nose pad bracket 210.

[0038] Furthermore, the vertical distance between the two side walls of the first adjusting member 2130 is slightly smaller than the inner distance between the two side walls of the first annular groove, so that the first nose pad 220 can slide longitudinally within the first moving path and improve the stability of the first nose pad 220 when sliding.

[0039] For the second nose pad 230, please refer to... Figure 6 See also Figure 5 In some embodiments, the second nose pad 230 includes a first support arm 2210, which is engaged with any one of the second slots to enable longitudinal movement of the second nose pad 230 relative to the nose pad support 210.

[0040] For example, the second nose pad 230 also includes a second nose flap 2320, which conforms to the user's other nostril when the user wears the smart glasses. A second support arm 2310 is integrally formed with the second nose flap 2320 and extends outward. The cross-sectional shape of the second support arm 2310 is generally rectangular. A second annular groove 2311 is provided at the end of the second support arm 2310 away from the second nose flap 2320. A second limiting groove 2312 is provided in the second annular groove 2311 at a position corresponding to the second limiting protrusion. The second limiting groove 2312 is V-shaped or inverted trapezoidal and is used to engage with the second limiting protrusion.

[0041] In this embodiment, due to the hollow design of the second adjusting member 2150, it has a certain amount of expansion and contraction space in the lateral direction, that is, it has a certain elasticity in the lateral direction. Therefore, when the second annular groove 2311 is assembled in the second limiting groove 2312, the nose pad can move up and down under the action of external force. Simultaneously, after the external force is released, the second adjusting member 2150 can recover its deformation under the action of elastic restoring force, thereby achieving the limiting and fixing of the nose pad position. This achieves the limiting cooperation between the second nose pad 230 and the nose pad support 210. Of course, in other embodiments of this application, the second limiting groove 2312 can also be a regular shape such as D-shaped, semi-circular, or trapezoidal.

[0042] In specific implementation, when the second support arm 2310 slides through the second notch to any of the second slots in the second moving path, the second support leaf 2320 is restricted from swinging back and forth by the limiting cooperation between the side wall of the second annular groove 2311 and the second adjusting member 2150, and the second support leaf 2320 is restricted from moving up and down by the locking cooperation between the second limiting protrusion and the second limiting groove 2312, so that the second nose pad 230 can move longitudinally and be limited relative to the nose pad support 210.

[0043] In the above technical solution, by setting multiple second slots, the position of the second nose pad 230 relative to the nose pad bracket 210 has multiple positions. The second support arm 2310 cooperates with different second slots to limit the position of the second nose pad 230 relative to the nose pad bracket 210 to different positions. On the basis of ensuring that the position of the second nose pad 230 relative to the nose pad bracket 210 is adjustable, the connection between the two is relatively stable after adjustment.

[0044] It is understood that the number of second checkpoints is not specifically limited in the embodiments of this application. For example, in the embodiments of this application, the number of second checkpoints is three. In other embodiments, the number of second checkpoints can be two, four, seven, or other numbers. In other embodiments, multiple second checkpoints can be arranged at equal intervals or at unequal intervals.

[0045] It is also understood that in some other embodiments, the second adjusting member 2150 is closed at both ends along the longitudinal direction, and multiple second slots are arranged longitudinally at intervals and are not connected to each other. The second support arm 2310 can be inserted or removed from any of the second slots, and the second support arm 2310 can be moved up and down, so as to realize the longitudinal movement of the second nose pad 230 relative to the nose pad bracket 210.

[0046] Furthermore, the vertical distance between the two side walls of the second adjusting member 2150 is slightly smaller than the inner distance between the two side walls of the second annular groove, so that the second nose pad 230 can slide longitudinally within the second moving path and improve the stability of the second nose pad 230 when sliding.

[0047] Furthermore, continue as Figure 6 As shown, the first support arm 2210 is located on the side of the first support leaf 2220 near its top, and the second support arm 2310 is located on the side of the second support leaf 2320 near its top. This results in a smaller angle between the first support leaf 2220 and the second support leaf 2320, providing a better wearing experience. If the nose pads are positioned in the middle of the bridge of the nose, the nose pads will open at a larger angle under the influence of the bridge of the nose when worn. A smaller angle allows them to fit snugly against both sides of the bridge of the nose, providing more stable support. This prevents the smart glasses from wobbling from side to side due to an excessively wide gap between the first nose pad 220 and the second nose pad 230. At the same time, the nose pads fixed at the top can fit well against the upper part of the bridge of the nose (nasal bone area) when worn. The bones in this area are harder and have a larger surface area, making them suitable for bearing support. Compared to the softer middle part of the bridge of the nose (cartilage area), there is no problem of pressure causing pain or indentations. In addition, the nose pads at the top do not come into contact with the alar cartilage or nasal opening, but are far away from the nasal cavity, only contacting the outer side of the nasal bone. This results in a higher degree of fit and does not put pressure on the nasal cavity, reducing discomfort when wearing them. At the same time, when the upper part of the nose pads is fixed, the support point is closer to the center line of gravity of the glasses frame (usually located at the top of the frame), which can reduce the tendency of the frame to tilt downwards due to gravity through the lever principle. For example, AR glasses may be heavier at the top because they are equipped with optical modules. Fixing the nose pads at the top can better balance the weight between the front and back, avoiding the problem of "glasses frequently slipping down when looking down".

[0048] In some embodiments, both the second nose pad 230 and the first nose pad 220 are made of a flexible, soft material. That is, the second nose pad 230 and the first nose pad 220 are flexible elastic elements, for example, the second nose pad 230 and the first nose pad 220 are elastic elements made of silicone material.

[0049] In some embodiments, the nose pad support 210 is made of elastic metal or rigid plastic material. For example, the nose pad support 210 can be made of elastic metal materials such as elastic steel, titanium, or glass copper, so that the first adjusting member 2130 and the second adjusting member 2150 can switch gears when the first nose pad 220 and / or the second nose pad 230 move longitudinally through their own elastic deformation.

[0050] In some embodiments, smart glasses meet at least one of the following conditions: (1) The width of the first annular groove 2211 and the width of the second annular groove 2311 each satisfy 0.3mm to 1.5mm. For example, the width of the first annular groove 2211 and the width of the second annular groove 2311 can each be 0.3mm, 0.5mm, 0.8mm, 1.0mm, 1.2mm, 1.5mm or any two of the above values.

[0052] (3) The length of the first limiting groove 2212 and the length of the second limiting groove 2312 are each within the range of 0.3mm to 1.5mm.

[0054] (5) The depth of the first limiting groove 2212 and the depth of the second limiting groove 2312 each satisfy 0.2mm to 0.8mm. For example, the width of the first limiting groove 2212 and the width of the second limiting groove 2312 can each be 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm or any two of the above values.

[0055] (6) The lateral spacing of the first bayonet 2131 and the lateral spacing of the second bayonet are each within the range of 0.8mm to 2mm.

[0056] (7) The longitudinal spacing between any two adjacent first limiting protrusions 2133 and the longitudinal spacing between any two adjacent second limiting protrusions each satisfy 1mm to 5mm. For example, the longitudinal spacing between any two adjacent first limiting protrusions 2133 and the longitudinal spacing between any two adjacent second limiting protrusions can each be 1mm, 1.2mm, 1.5mm, 1.8mm, 2mm, 2.4mm, 2.8mm, 3mm, 3.5mm, 4.5mm, 5mm or any two of these values.

[0058] (9) The longitudinal width of the first limiting protrusion 2133 and the longitudinal width of the second limiting protrusion are each satisfied to be 0.1mm to 0.5mm. For example, the longitudinal width of the first limiting protrusion 2133 and the longitudinal width of the second limiting protrusion can each be 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm or any two of the values.

[0059] In summary, in the smart glasses of this application, at least one of the first nose pad 220 and the second nose pad 230 can move and be limited in the longitudinal direction. That is, only one nose pad is used to achieve the adjustment and fixation of the relative position between the two nose pads, so that the nose pad assembly 20 can be adapted to users with different face shapes, thereby improving the convenience of using the smart glasses for different users.

[0060] It is understood that the above embodiments are illustrated by the example of the first nose pad 220 and the second nose pad 230 being movably disposed on the nose pad bracket 210. In other embodiments, one of the first nose pad 220 and the second nose pad 230 is movably disposed on the nose pad bracket 210, while the other is fixed to the nose pad bracket 210. Taking the example of the second nose pad 230 being fixed to the nose pad bracket 210, in this case, one end of the nose pad bracket 210 is no longer provided with the second adjusting member 2150, and the second support arm 2310 fixes the second nose pad 230 to the nose pad bracket 210 by screws, which also facilitates the nose pad assembly 20 to adapt to users with different face shapes.

[0061] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
