[0032] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0033] Figures 1 to 8 This is a schematic diagram of the structure of the nose pad assembly and smart glasses of the present invention, wherein: Figure 1 The figure shows a three-dimensional structural diagram of the nose pad assembly of the present invention. Figure 2 The figure shows the exploded structure of the nose pad assembly of the present invention. Figure 3 The nose pad assembly of the present invention is shown along Figure 1 Schematic diagram of the cross-sectional structure along the AA line. Figure 4 The nose pad assembly of the present invention is shown along Figure 1 Schematic diagram of the cross-sectional structure of the middle BB line, Figure 5 The figure shows a three-dimensional structure diagram of the glasses body of the smart glasses of the present invention. Figure 6 The figure shows a rear view structure diagram of the glasses body of the smart glasses of the present invention. Figure 7 The glasses main body of the smart glasses of the present invention is shown along Figure 6 Schematic diagram of the cross-sectional structure of the CC line (enlarged state), Figure 8 Shown Figure 6 For the sake of convenience, only the parts related to the present invention are shown in the figure.

[0034] It should be noted that the directional indications involved in the present invention (such as up, down, front, back, etc.) are only used to explain the relative position relationship between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly; in addition, the descriptions of "first", "second", etc. involved in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features.

[0035] Depend on Figures 1 to 5 It can be seen that the nose pad assembly of the present invention, applied to smart glasses, includes:

[0036] A support rod 10, a first end of which is mounted on a glasses body 50 of the smart glasses;

[0037] The mounting seat 20 is fixed to the second end of the support rod 10 away from the eyeglass body 50, and the mounting seat 20 is provided with a receiving cavity 21;

[0038] The nose pad 30 is provided with a plug connector 31 inserted into the accommodating cavity 21, a gap is provided between the nose pad 30 and the mounting seat 20, and a gap is provided between the plug connector 31 and the side walls and bottom surface of the accommodating cavity 21;

[0039] And the elastic connection structure is connected between the plug connector 31 and the side wall of the accommodating cavity 21. When the nose pad 30 is squeezed, the plug connector 31 pushes the elastic connection structure to produce elastic deformation, and the plug connector 31 moves relative to the side wall and bottom surface of the accommodating cavity 21.

[0040] When the smart glasses are worn, the nose pad 30 of the nose pad assembly fits the user's nose, and the nose pad 30 is squeezed by the nose. Due to the shape of the side of the nose, the nose pad 30 is subjected to squeezing force in the oblique direction. Since there is a gap between the nose pad 30 and the mounting seat 20, there is also a gap between the plug joint 31 and the side wall and the bottom surface of the accommodating cavity 21. When the nose pad 30 is squeezed, it can move toward the side of the mounting seat 20, and the plug joint 31 moves with the nose pad 30 and pushes the elastic connection structure provided between the plug joint 31 and the side wall of the accommodating cavity 21 to produce elastic deformation. The plug joint 31 can tilt relative to the side wall and the bottom surface of the accommodating cavity 21, thereby causing the nose pad 30 to tilt accordingly, making it easier for the nose pad 30 to fit the nose and suitable for the noses of different users. In addition, the elastic force generated by the elastic connection structure can react on the nose pad 30, making the nose pad 30 fit the nose more closely. The nose pad assembly of the utility model solves the problem that the nose pad of the nose pad cannot fit the noses of different users, and can improve the user experience.

[0041] In the present invention, the elastic connection structure is connected between the upper side wall of the accommodating cavity 21 and the lower side wall of the accommodating cavity 21 , and a mounting through hole 32 for the elastic connection structure to pass through is provided on the plug connector 31 .

[0042] As 2, Figure 3 and Figure 4 As shown, the elastic connection structure is a spring 41. Of course, the elastic connection structure can also be set to an elastic rope.

[0043] To facilitate installation, accommodating holes 22 communicating with the accommodating cavity 21 are respectively provided on the side walls on the upper side of the accommodating cavity 21 and the side walls on the lower side of the accommodating cavity 21. Mounting ends 42 that are inserted into the accommodating holes 22 on the corresponding sides are respectively installed at both ends of the spring 41. A limiting structure is respectively provided on each mounting end 42 to prevent the mounting end 42 from sliding into the interior of the accommodating cavity 21. The spring 41 between the two mounting ends 42 is in a stretched state.

[0044] Specifically, an accommodating groove 23 is provided on the outer side wall of the accommodating cavity 21, passing through the accommodating hole 22. Both ends of the accommodating groove 23 are closed. A through hole is provided on the mounting end 42 along the extension direction of the accommodating groove. The limiting structure passes through the through hole and is locked inside the accommodating groove 23, which can confine the limiting structure inside the accommodating groove 23 and prevent the limiting structure from being separated from the mounting end 42. Typically, the limiting structure is configured as a limiting plate 43, which is plugged into the through hole and fits against the bottom surface of the accommodating groove 23; of course, it can also be configured as a limiting rod.

[0045] In some other embodiments, the elastic connection structure may also be provided between the plug connector 31 and the bottom surface of the accommodating cavity 21 . In this case, the elastic connection structure is a spring, an elastic rod, or the like.

[0046] Depend on Figures 5 to 8 As can be seen, the present invention also discloses a pair of smart glasses, which include a glasses body 50, left and right temples (not shown) respectively connected to the left and right sides of the glasses body 50, and nose pads mounted on the glasses body 50. The nose pads include two sets of the above-mentioned nose pad assemblies spaced apart in the left-right direction, the nose pads 30 of the two sets of nose pad assemblies are adjacently arranged, and the first ends of the support rods 10 of the two sets of nose pad assemblies are respectively mounted on the glasses body 50. When wearing the smart glasses, the two sets of nose pad assemblies are respectively clamped on both sides of the nose, and the nose pads 30 of the two sets of nose pad assemblies are respectively fitted to the nose, which can enhance the fit between the nose pads and the user's nose and improve the user experience.

[0048] like Figure 6 、 Figure 7 and Figure 8 As shown, the sliding connection mechanism includes a runway-shaped guide rail 53 arranged along the circumference of the elongated through-hole 51, an annular transmission belt 71 mounted on the runway-shaped guide rail 53 and capable of rotating around the runway-shaped guide rail 53, and a sliding structure slidably mounted between the two long sides of the runway-shaped guide rail 53. The support rod 10 is fixedly mounted on the sliding structure, and the sliding structure is fixedly connected to one side of the annular transmission belt 71. Because the sliding structure is slidably mounted between the two long sides of the runway-shaped guide rail 53 and is fixedly connected to one side of the annular transmission belt 71, when the annular transmission belt 71 rotates around the runway-shaped guide rail 53, it can drive the sliding structure to slide along the two long sides of the runway-shaped guide rail 53, thereby driving the nose pad assembly to slide, thereby adjusting the vertical position of the nose pad assembly. Typically, an annular groove is provided on the annular transmission belt 71, and the annular groove on the annular transmission belt 71 is clamped on the runway-shaped guide rail 53, and the annular transmission belt 71 is restricted by the shape of the runway-shaped guide rail 53 to form a runway shape; of course, the annular transmission belt 71 can also be wrapped around the outer peripheral side of the runway-shaped guide rail 53, leaving a gap between the annular transmission belt 71 and the shell of the glasses body 50 provided with the elongated through hole 51.

[0049] The sliding drive mechanism includes a plurality of transmission teeth 72 arranged sequentially along the circumferential direction on an endless transmission belt 71. These teeth 72 form a rack structure. The mechanism also includes a motor 73 fixedly mounted within the eyeglass body 50 and electrically connected to the mainboard 54. A gear 74 is mounted on the output shaft of motor 73, meshing with the rack structure. During adjustment, motor 73 drives gear 74 to rotate. The meshing of gear 74 with the rack structure drives the endless transmission belt 71 to rotate around the racetrack-shaped guide rail 53.

[0050] Specifically, an upper connecting hole and a lower connecting hole are respectively provided at the upper end and the lower end of the runway-shaped guide rail 53 corresponding to the elongated through hole 51, and the width of the upper connecting hole and the lower connecting hole is equal to the spacing between the two long sides of the runway-shaped guide rail 53; the sliding structure includes an ugly-covering plate 52 that passes through the upper connecting hole and the lower connecting hole in sequence, and the ugly-covering plate 52 is slidably installed between the two long sides of the runway-shaped guide rail 53, and also includes a cover plate 11 fixedly installed on the ugly-covering plate 52, and one side of the cover plate 11 is fixedly connected to the corresponding side of the annular transmission belt 71. Usually, a protrusion is provided on one side of the cover plate 11, and a card slot is provided on the annular transmission belt 71, and the protrusion is fixedly installed inside the card slot; the support rod 10 passes through the ugly-covering plate 52 and is fixedly connected to the cover plate 11.

[0051] In other embodiments, the sliding connection mechanism includes straight guide rails disposed along opposite sides of the elongated through-hole 51, visor plates 52 disposed corresponding to the elongated through-hole 51, and grooves adapted to the straight guide rails disposed along the long sides of the visor plates 52. Typically, the straight guide rails are configured as T-shaped ridges, and the grooves are configured as T-shaped grooves, with the T-shaped ridges and grooves interfitting to achieve installation. The rack structure of the sliding drive mechanism is disposed on the side of the visor plate 52 slide away from the elongated through-hole 51, and the support rod 10 is fixedly connected to the visor plates 52. In this case, the visor plates 52 can both enable the nose pad assembly to slide along the elongated through-hole 51 and also serve to shield the elongated through-hole 51.

[0052] In the present invention, an electronic component 80 is embedded inside the nose pad 30, and an FPC circuit board 60 is connected between the electronic component 80 and the main board 54 inside the eyeglass body 50. The corresponding functions can be realized through the electronic component 80, for example, the electronic component 80 is a bone voiceprint sensor, a pressure sensor, etc.

[0053] In order to facilitate installation, the support rod 10 is configured as a hollow tube, which is communicated with the accommodating cavity 21 to facilitate routing of the FPC circuit board 60 .

[0054] like Figure 2 and Figure 4 As shown, a bracket 90 is provided inside the nose pad 30 for protecting the electronic components 80 and the FPC circuit board 60 embedded inside the nose pad 30 .

[0055] Specifically, the bracket 90 includes a plate body 91 and an extension arm 92 connected to the side of the plate body 91.
