[0046] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0047] Example 1

[0048] like Figures 1-12 As shown in the figure, the adjustable nose pad proposed in this embodiment can be used in AR glasses or VR glasses. According to the structural space of the glasses, the adjustable nose pad is designed and laid out in the glasses shell. The adjustable nose pad can be supported on the brow bridge. The adjustable nose pad can also be used in other glasses.

[0049] This adjustable nose pad may include a pair of nose pad links 3 with pad leaves 4 mounted on them, a link adjustment member 1, and a locking member 2. The nose pad links 3 connect the pad leaves 4 and the eyeglass housing 5, supporting the glasses on the bridge of the nose when worn. The link adjustment member 1 adjusts the position of the pair of nose pad links 3 simultaneously to fit the wearer's nose. The locking member 2 secures the adjusted wedge, and can be released and locked. When the locking member 2 is released, the link adjustment member 1 can be adjusted; once adjusted, the locking member 2 locks the link adjustment member 1 in place, preventing movement, thus determining the position of the pair of nose pad links 3.

[0050] Specifically, such as Figures 1-4 As shown, in this embodiment, the linkage adjustment member 1 may include a wedge 11, with a first rack 12 disposed on the lower bottom surface of the wedge 11. The first rack 12 meshes with an adjustment gear 13, and the center surface of the wedge 11 coincides with the center surface of the eyeglass housing 5. A pair of nose pad linkages 3 are symmetrical about the center surface of the wedge 11. The nose pad linkages 3 may include a first rod 31 and a second rod 32 connected to each other. The connection between the first rod 31 and the second rod 32 is rotatably connected to a shaft 34 on the inner wall of the eyeglass housing 5, and the end of the second rod 32 is connected to the nose pad 4. By rotating the adjustment gear 13, the wedge 11 moves horizontally, and the end of the first rod 31 moves along the inclined surface 111 of the wedge 11.

[0051] The wedge 11 is a block with a right-angled trapezoidal cross-section. The wedge 11 moves horizontally along the front-back direction of the glasses by rotating the adjusting gear 13. The angle between the first rod 31 and the second rod 32 of the nose pad connecting rod 3 can be set. Through the connection between the first rod 31 and the second rod 32, the nose pad connecting rod 3 can rotate on the shaft 34 inside the glasses housing 5. As the wedge 11 moves horizontally, the inclined surface 111 of the wedge drives the end of the first rod 31 to move up and down. During this up-and-down movement, the end of the first rod 31 remains in contact with the inclined surface 111 of the wedge 11, thus rotating the nose pad connecting rod 3 and causing the second rod 32 to swing. The orientation of the two second rods 32 of the pair of nose pad connecting rods 3 changes symmetrically, simultaneously moving closer to or further apart from the center plane, so that the distance between the two nose pads 4 is suitable for the wearer.

[0052] The locking component 2 may include a locking block 21, with a first compression spring 22 at its upper end. The first compression spring 22 presses the locking block 21 against the upper surface of the wedge block 11, thus securing the locking block 21 to the upper surface of the wedge block 11. During the adjustment of the linkage adjustment component 1, the wearer simultaneously moves the locking block 21, further compressing the first compression spring 22, causing the locking block 21 to move upward and separate from the wedge block 11, allowing the wedge block 11 to move. After the linkage adjustment component 1 is adjusted, the wearer releases the locking block 21, causing the first compression spring 22 to spring up, resulting in the locking block 21 moving downward and locking the upper surface of the wedge block 11, preventing further movement of the wedge block 11. This fixes the position of the pair of nose bridge linkages 3, allowing the wearer to comfortably and reliably wear the device.

[0053] The eyeglass housing 5 should have a corresponding housing structure designed for the components of this adjustable nose pad.

[0054] Specifically, such as Figure 5 and Figure 6 As shown, in this embodiment, the adjusting gear 13 may include a spur gear 131 and rotating shafts 132 respectively disposed at both ends of the spur gear 131. The rotating shafts 132 pass through a shaft hole 133 disposed within the eyeglass housing 5. The spur gear 131 is adapted to the first rack 12 of the wedge 11. The tooth length of the spur gear 131 may be less than the tooth length of the first rack 12 of the wedge 11. Rotating the spur gear 131 can stably drive the wedge 11 to move. The inner diameter and length of the shaft hole 133 are adapted to the outer diameter and length of the rotating shaft 132, allowing the rotating shaft 132 to rotate stably and flexibly within the shaft hole 133.

[0055] To facilitate adjustment of the adjustment gear 13 by the wearer, an opening 16 is provided on the lower middle part of the eyeglass housing 5, exposing the teeth of the adjustment gear 13 in the opening 16, allowing the teeth of the adjustment gear 13 to be rotated within the opening 16. The opening 16 is located on the lower middle part of the AR eyeglass housing 5 and can be a long, narrow opening. The middle part of the spur gear 131 is located within the opening 16. The opening 16 does not need to be too large; it only needs to allow the spur gear 131 to be rotated effectively within the opening 16.

[0056] like Figure 7 and Figure 8 In this embodiment, the wedge 11 is specifically structured such that a first guide block 14 is provided at both ends of the wedge 11, and the first guide block 14 is disposed in a first guide groove 15 inside the eyeglass housing 5. The first guide groove 15 is adapted to the first guide block 14, and the first guide block 14 can slide within the first guide groove 15, guiding and restricting the movement of the wedge 11, so that the movement of the wedge 11 is horizontally stable and will not disengage from the adjusting gear 13. The inclined surface 111 of the wedge 11 can face the interior of the eyeglass housing 5, and the flat upper top surface of the wedge 11 is close to the front wall 51 of the eyeglass housing.

[0057] like Figure 9 and Figure 10 As shown, in this embodiment, to facilitate the operation of the locking component 2, a toggle block 23 is provided on the side wall of the locking block 21, and an elongated hole 26 is provided on the front wall 5 of the eyeglass housing. The toggle block 23 can extend out of the elongated hole 26. When the toggle block 23 is pushed upward in the elongated hole 26, the locking block 21 separates from the wedge block 11. The width of the elongated hole 26 is adapted to the diameter of the toggle block 23, and the length of the elongated hole 26 can be slightly larger than the diameter of the toggle block 23. When the toggle block 23 is not pushed upward, the toggle block 23 is located at the lower end of the elongated hole 26. When the toggle block 23 is pushed upward, the toggle block 23 is located at the upper end of the elongated hole 26, and the locking block 21 separates from the wedge block 11.

[0058] The wedge 11 and the locking block 21 are secured by a rack and pinion structure. Specifically, a second rack 24 is provided on the upper top surface of the wedge 11, and a third rack 25 that meshes with the second rack 24 is provided on the bottom surface of the locking block 21. After the actuating block 23 is released, the first compression spring 22 rebounds, engaging the third rack 25 with the second rack 24, thus positioning the wedge 11.

[0059] To ensure stable operation of the locking component 2, the upper end of the first compression spring 22 is connected to the inner wall of the eyeglass housing 5. A second guide block 27 is provided on each of the two opposite side walls of the locking block 21. Both side walls can be adjacent to the actuating block. The second guide block 27 is located within a second guide groove 28 inside the eyeglass housing 5. The second guide groove 28 and the second guide block 27 are adapted to each other, limiting the movement of the locking block 21 and ensuring that the locking block 21 moves vertically and stably under the elastic force of the first compression spring 22.

[0060] like Figure 11 and Figure 12 As shown, in this embodiment, the nose pad connecting rod 3 has the following specific structure: the first rod 31 and the second rod 32 are both connected to the outer wall of the bushing 33. The bushing 33 passes through the shaft 34 inside the eyeglass housing 5. The shaft 34 fixes the front and rear positions of the bushing 33. The bushing 33 can rotate flexibly on the shaft 34. The included angle between the first rod 31 and the second rod 32 can be about 90 degrees.

[0061] To stably press the end of the second rod 32 against the inclined surface 111 of the wedge block 11, a second compression spring 35 is vertically mounted on the first rod 31. The upper end of the second compression spring 35 is connected to the inside of the eyeglass housing 5. The elastic force of the second compression spring 35 presses the end of the first rod 31 against the inclined surface 111 of the wedge block 11. The second rod 32 passes through a hole in the eyeglass housing 5 and connects to the nose pad 4. The lower end of the second compression spring 35 can be connected to the middle of the first rod 31 through a connecting post. The elastic force of the second compression spring 35 keeps the end of the first rod 31 pressed against the inclined surface 111 of the wedge block, and the end of the first rod 31 will not separate from the inclined surface 111 of the wedge block during the movement of the wedge block 11.

[0062] In order to allow the end of the first rod 31 to slide flexibly on the wedge inclined surface 111, a spherical sliding block 36 is provided at the end of the first rod 31. The surface of the sliding block 36 that contacts the inclined surface 111 is set as a plane. This plane fits against the inclined surface 111 and can slide easily on the inclined surface 111.

[0063] A hole is provided on the eyeglass housing 5 for the second rod 32 to pass through, allowing the second rod 32 to move freely within this hole during its swinging motion. A connecting block can be provided at the end of the second rod 32, through which it connects to the nose pad 4.

[0064] This adjustable nose pad occupies little internal space in the glasses housing 5 and is easy to adjust. After wearing, simultaneously turn the lever 23 upwards and rotate the adjusting gear 13 until a comfortable fit is achieved. Then release the lever 23 to complete the adjustment in one go.

[0065] Example 2

[0066] like Figure 13 As shown, the glasses provided in this embodiment include the adjustable nose pad described in Embodiment 1. A corresponding component mounting structure space can be designed in the housing of AR, VR, or other glasses to install the adjustable nose pad from Embodiment 1.

[0067] like Figure 6 , Figure 8 , Figure 10 , Figure 12 , Figure 13 As shown, the mounting structure of each part can be designed on the front wall 51 of the eyeglass housing, and the shaft hole 133, the first guide groove 15, the opening 16, the second guide groove 28, the shaft 34, the elongated hole 26, etc. can be provided. The accommodating space of each part can be designed on the rear wall of the eyeglass housing. After the front wall and the rear wall are fastened together, the nose pad can be adjusted and stably located inside the eyeglass housing 5.

[0068] The adjustable nose pads and eyeglasses according to the present invention have been described above by way of example with reference to the accompanying drawings. However, those skilled in the art should understand that various modifications can be made to the adjustable nose pads and eyeglasses of the present invention without departing from the scope of the invention. Therefore, the scope of protection of the present invention should be determined by the contents of the appended claims.
