[0057] Glasses generally include a glasses frame, glasses lenses and glasses legs. In order to make the glasses comfortable to wear, glasses nose pads are generally arranged where the glasses frame contacts the user's nose bridge. Generally, a nose pad opening is provided on the glasses frame for the glasses nose pad to be installed.

[0058] At present, in the existing glasses, the nose pad is generally fixed to the inner side of the glasses frame. However, the fixed connection between the nose pad and the glasses frame makes it easy for dust to accumulate on the nose pad when the glasses are not in use, and it is also easy to cause damage to the nose pad in an accident.

[0059] The present invention provides a pair of smart glasses.

[0060] See also Figures 1 to 3 In one embodiment of the present invention, the smart glasses include a frame body 100, a nose pad module 200 and a control component. The frame body 100 is provided with a nose pad opening 110. The nose pad module 200 has a hidden state and a use state. In the hidden state, the nose pad module 200 does not protrude from the plane where the nose pad opening 110 is located; in the use state, the nose pad module 200 protrudes from the nose pad opening 110 to contact the bridge of the nose. The control component includes a controller 910 and an adjustment component 500 electrically connected to the controller 910. The controller 910 is used to switch the hidden state and the use state through the adjustment component 500.

[0061] It can be understood that the frame body 100 includes two temples, which are used to overlap the ears to facilitate the wearing of the smart glasses. For the convenience of explanation, the side of the frame body 100 where the temples are installed is defined as the inner side of the smart glasses, and the side opposite to the temples is defined as the outer side of the smart glasses. In one embodiment, the smart glasses also include an optical module installed on the frame body 100.

[0062] The frame body 100 is provided with a nose pad opening 110, and the nose pad module 200 is installed at the nose pad opening 110. When the smart glasses are not in use, the controller 910 controls the adjustment component 500, and the nose pad module 200 is hidden in the nose pad opening 110 through the adjustment component 500, that is, the nose pad module 200 does not protrude from the side of the frame body 100 facing the inner side of the smart glasses, and the nose pad module 200 is in a hidden state. When the smart glasses are in use, the controller 910 controls the adjustment component 500, and the nose pad module 200 is protruded from the nose pad opening 110 through the adjustment component 500 to contact the bridge of the nose, so as to facilitate wearing of the smart glasses, and the nose pad module 200 is in a use state. In this way, when the smart glasses are used, the nose pad module 200 protrudes from the nose pad opening 110 and contacts the bridge of the nose, thereby ensuring the normal use of the nose pad module 200; when the smart glasses are not in use, the nose pad module 200 is hidden in the nose pad opening 110, thereby avoiding accidental collision of the nose pad module 200, improving the protection of the nose pad module 200, and further improving the protection of the smart glasses, while also avoiding dust accumulation at the nose pad module 200, making it convenient to clean the smart glasses.

[0063] It can be understood that the nose pad module 200 includes a left nose pad and a right nose pad, which are used to contact the left and right sides of the nose bridge respectively. Correspondingly, the frame body 100 is also provided with two nose pad openings 110, which are used to install the left nose pad and the right nose pad respectively.

[0064] The technical solution of the present invention is to set a frame body 100, a nose pad module 200 and a control component in the smart glasses, wherein the frame body 100 is provided with a nose pad opening 110, and the nose pad module 200 has a hidden state and a use state. In the hidden state, the nose pad module 200 is located in the nose pad opening 110; in the use state, the nose pad module 200 protrudes from the nose pad opening 110 to contact the bridge of the nose. The control component includes a controller 910 and an adjustment component 500 electrically connected to the controller 910, and the controller 910 is used to switch the hidden state and the use state through the adjustment component 500. In this way, the nose pad module 200 is set to two states. When the smart glasses are used, the nose pad module 200 is protruded from the nose pad opening 110; when the smart glasses are not used, the nose pad module 200 is located in the nose pad opening 110. In this way, accidental collision of the nose pad module 200 when the smart glasses are not in use is avoided, the protection of the nose pad module 200 is improved, and the protection of the smart glasses is further improved. At the same time, the controller 910 controls the adjustment component 500 to switch the hidden state and the use state of the nose pad module 200, thereby improving the automation and intelligence of the smart glasses and improving the user experience of the smart glasses.

[0065] See also Figures 4 to 6In an embodiment of the present invention, the nose pad module 200 includes a bendable nose pad body 400, which is laid flat in the frame body 100 in a hidden state; in a use state, the adjustment component 500 is used to bend the nose pad body 400 and arch it toward the nose pad opening 110, so that at least a portion of the nose pad body 400 protrudes out of the nose pad opening 110.

[0066] Specifically, in the solution shown in the figure of the present invention, the nose pad module 200 includes a bendable nose pad body 400. It can be understood that the nose pad body 400 can be partially bendable or all bendable. This is not limited here.

[0067] When the nose pad module 200 is in the hidden state, the nose pad body 400 is laid flat in the frame body 100. It can be understood that the frame body 100 is a hollow structure, and a receiving space is formed inside it to install various structural parts. In the hidden state, the nose pad body 400 is located in the receiving space and laid flat on the frame body 100.

[0068] It can be understood that a nose pad opening 110 is formed on a side wall of the frame body 100 facing the inner side of the smart glasses. In one embodiment, in the hidden state, at least part of the nose pad body 400 covers the nose pad opening 110. At this time, if the smart glasses are observed from the inner side, part of the nose pad body 400 can be seen from the nose pad opening 110, and the nose pad body 400 does not protrude from the receiving space of the frame body 100. In this way, exposure of other structural parts in the receiving space of the frame body 100 is avoided, damage to other structures in the frame body 100 is avoided, and the aesthetics of the smart glasses in the hidden state is also improved.

[0069] When the nose pad module 200 is in use, the nose pad body 400 is bent under the adjustment of the adjustment component 500, so that the nose pad body 400 is arched toward the nose pad opening 110 and protrudes from the nose pad opening 110. Here, there is no restriction on the size of the nose pad opening 110 and the bending angle of the nose pad body 400, as long as it can be ensured that the nose pad body 400 can protrude from the nose pad opening 110 after bending.

[0070] Of course, in other embodiments, the nose pad body 400 may not be flat, but the nose pad body 400 may always maintain the shape of being in contact with the bridge of the nose. When the smart glasses are not in use, the nose pad body 400 is adjusted by the adjustment component 500 to directly retract into the nose pad opening 110; when the smart glasses are in use, the nose pad body 400 is adjusted by the adjustment component 500 to directly extend out of the nose pad opening 110.

[0071] See also Figures 4 to 6 , Fig.10 and Fig.11In an embodiment of the present invention, the nose pad body 400 includes a bendable portion 410 and a non-bendable portion 420 connected to each other, and the adjustment component 500 includes a pushing member 510 and an ejecting member 520 opposite to the nose pad opening 110. The pushing member 510 drives the nose pad body 400 to move toward the nose pad opening 110, and at the same time, the ejecting member 520 ejects the nose pad body 400 toward the outside of the nose pad opening 110, so that the bendable portion 410 at the nose pad opening 110 is bent, so that under the push of the pushing member 510, the non-bendable portion 420 and the bent bendable portion 410 protrude from the nose pad opening 110.

[0072] Specifically, a mounting groove 120 is provided in the frame body 100, and the nose pad body 400 is provided in the mounting groove 120. Thus, the mounting groove 120 provides a guide for the installation of the nose pad body 400, and also provides an installation position. The nose pad body 400 includes a bendable portion 410 and a non-bendable portion 420. Under the adjustment of the adjustment component 500, the bendable portion 410 and the non-bendable portion 420 can both protrude from the nose pad opening 110 and contact the bridge of the nose. The provision of the non-bendable portion 420 improves the shape stability of the nose pad body 400 in the use state.

[0073] In the scheme shown in the figure of the present invention, the nose pad body 400 includes a plurality of bendable parts 410 and a plurality of non-bendable parts 420, wherein a bendable part 410 is arranged adjacent to a non-bendable part 420. That is, the nose pad body 400 is set as a section-shaped structure. In this way, the setting of the section-shaped structure improves the convenience of switching the nose pad body 400 between the hidden state and the use state. At the same time, the setting of the plurality of bendable parts 410 and the plurality of non-bendable parts 420 further improves the morphological stability of the nose pad body 400 in the use state. Here, there is no restriction on the number of the bendable parts 410 and the non-bendable parts 420.

[0074] See also Figure 5 , the adjustment component 500 includes a pusher 510 and an ejector 520. When the nose pad module 200 is switched from the hidden state to the use state, the pusher 510 drives the nose pad body 400 laid on the frame body 100 to move toward the nose pad opening 110. At the same time, the ejector 520 arches the nose pad body 400 toward the outside of the nose pad opening 110, that is, the ejector 520 ejects the nose pad body 400 toward the inside of the smart glasses, so that the bendable portion 410 is bent, so that the nose pad body 400 moving toward the nose pad opening 110 can protrude from the nose pad opening 110. In this way, as the pusher 510 continues to push, the nose pad body 400 continues to protrude out of the nose pad opening 110 until the nose pad body 400 reaches the first preset height. It is worth noting that the first preset height refers to the height extending along the front-back direction of the line of sight after the smart glasses are worn. The first preset height can be set according to demand, and the first preset height is not limited here.

[0075] When the nose pad module 200 is switched from the use state to the hidden state, the pushing member 510 drives the portion of the nose pad body 400 remaining in the nose pad opening 110 to move in a direction away from the nose pad opening 110. It can be understood that the ejection member 520 does not work at this time, that is, the ejection member 520 no longer ejects the nose pad body 400, so that under the drive of the pushing member 510, the protruding nose pad body 400 can be retracted into the nose pad opening 110 and laid flat in the frame body 100.

[0076] It can be understood that in order to ensure that the non-bendable portion 420 and the bendable portion 410 after bending can protrude from the nose pad opening 110, the size of the non-bendable portion 420 is smaller than the size of the nose pad opening 110, and the size of the bendable portion 410 is smaller than the size of the nose pad opening 110. In one embodiment, the width of the non-bendable portion 420 is consistent with the width of the bendable portion 410 to facilitate the molding of the nose pad body 400. In addition, the width of the non-bendable portion 420 and the width of the bendable portion 410 are slightly smaller than the width of the nose pad opening 110, so that the exposure of the structural parts in the nose pad opening 110 is avoided when observing from the inside of the smart glasses; at the same time, it is also ensured that the non-bendable portion 420 and the bendable portion 410 can protrude from the nose pad opening 110. It is worth noting that slightly smaller means slightly smaller in the conventional sense. In one embodiment, the difference range can be 0.2mm. There is no restriction on the difference between the width of the non-bendable portion 420 and the bendable portion 410 and the width of the nose pad opening 110. The length of the non-bendable portion 420 is greater than the length of the bendable portion 410, so as to ensure the structural strength of the nose pad body 400 protruding from the nose pad opening 110, that is, to ensure the structural strength of the nose pad body 400 when the nose pad module 200 is in use. The lengths of the non-bendable portion 420 and the bendable portion 410 are both less than the length of the nose pad opening 110, so as to ensure that the nose pad body 400 can protrude from the nose pad opening 110. In one embodiment, Figure 1 As shown, the length of the nose pad opening 110 is greater than or equal to the sum of the lengths of the three non-bendable portions 420 and the three bendable portions 410 . Here, no limitation is imposed on the sizes of the nose pad opening 110 , the non-bendable portions 420 and the bendable portions 410 .

[0077] In one embodiment, the bendable portion 410 is configured to be made of materials such as silicone and rubber, and the non-bendable portion 420 is configured to be made of materials such as hard plastic and sheet metal. The specific materials of the bendable portion 410 and the non-bendable portion 420 are not limited herein.

[0078] Of course, in other embodiments, the nose pad body 400 may also include only the bendable portion 410. Under the adjustment of the adjustment component 500, the bendable portion 410 may be bent and deformed to protrude from the nose pad opening 110 to contact the bridge of the nose. In one embodiment, the bendable portion 410 is configured as a deformable plastic with a certain structural strength, so that it is ensured that the bendable portion 410 can be bent and deformed to protrude from the nose pad opening 110, and the shape stability of the bendable portion 410 in use is also ensured. More specifically, in one embodiment, the adjustment component 500 may be a telescopic device. When the telescopic device is extended, the bendable portion 410 is driven to protrude from the nose pad opening 110. When the telescopic device is retracted, the bendable portion 410 is driven to retract into the nose pad opening 110.

[0079] Of course, in other embodiments, the adjustment assembly 500 may also include a motor and a telescopic push rod, the telescopic push rod corresponds to the nose pad opening 110, and the end of the telescopic push rod away from the motor is connected to the nose pad body 400. When the nose pad body 400 needs to be pushed out, the motor works to drive the telescopic push rod to extend and drive the nose pad body 400 to protrude out of the nose pad opening 110. When the nose pad body 400 needs to be hidden, the motor drives the telescopic push rod to retract and drive the nose pad body 400 to retract into the nose pad opening 110. In this way, the nose pad body 400 can be hidden and used.

[0080] See also Figures 6 to 9 In an embodiment of the present invention, the adjustment component 500 also includes a power component 600 electrically connected to the controller 910, the pusher 510 includes a meshing first gear 512 and a flexible rack 511, the flexible rack 511 is provided on the nose pad body 400, and the power component 600 is used to drive the first gear 512 to rotate.

[0081] Specifically, in the scheme shown in the figure of the present invention, the pusher 510 includes a first gear 512 and a flexible rack 511 that are meshed with each other, and the flexible rack 511 is laid on the bendable portion 410 and the non-bendable portion 420, that is, the flexible rack 511 is located on the side of the nose pad body 400 away from the nose pad opening 110. It can be understood that the flexible rack 511 is configured as a flexible material, so that the flexible rack 511 has a certain deformation ability. In this way, when the bendable portion 410 is bent, the flexible rack 511 can also bend accordingly, so as not to affect the bending effect of the bendable portion 410, and can protrude from the nose pad opening 110 with the nose pad body 400. When the nose pad body 400 is laid flat in the frame body 100 and the bendable portion 410 is not bent, the flexible rack 511 can also be restored to its original state without affecting and meshing with the first gear 512. In one embodiment, the flexible rack 511 is made of materials such as silicone and rubber.

[0082] The first gear 512 is installed in the frame body 100. In one embodiment, a gear installation position is provided on the groove wall of the installation groove 120. The first gear 512 is installed in the gear installation position, and the first gear 512 can rotate relative to the gear installation position. In this way, when the nose pad module 200 is switched from the hidden state to the use state, the controller 910 controls the power assembly 600 to work, so that the power assembly 600 drives the first gear 512 to rotate, drives the flexible rack 511 to move relative to the first gear 512, thereby driving the nose pad body 400 to move toward the nose pad opening 110, and at the same time, the ejector 520 works to eject the nose pad body 400 at the nose pad opening 110 toward the outside of the nose pad opening 110, that is, the nose pad body 400 at the nose pad opening 110 is ejected toward the inside of the smart glasses, so that the bendable portion 410 is bent, and then the nose pad body 400 can protrude from the nose pad opening 110 driven by the flexible rack 511. When the nose pad module 200 is switched from the use state to the hidden state, it is only necessary for the power assembly 600 to drive the first gear 512 to rotate in the reverse direction, and the specific movement process will not be described in detail.

[0083] Of course, in other embodiments, the push member 510 can also be a push rod and a push motor, the push motor is electrically connected to the controller 910, the push motor is arranged on the frame body 100, one end of the push rod is connected to the push motor, and the other end is connected to the nose pad body 400. When the push motor is working, the push rod drives the nose pad body 400 to move toward the nose pad opening 110. In one embodiment, two push rods are provided, and the two push rods are respectively arranged at both ends of the nose pad body 400 along the length direction thereof. Driven by the two push rods, both ends of the nose pad body 400 move toward the nose pad opening 110, so that the nose pad body 100 arches out of the nose pad opening.

[0084] See also Figure 5 and Fig. 9 In an embodiment of the present invention, two flexible racks 511 are provided, and the two flexible racks 511 are respectively provided at two ends of the nose pad body 400 and on both sides of the nose pad opening 110 . Two first gears 512 are provided, and one first gear 512 is meshed with one flexible rack 511 .

[0085] Specifically, in the solution shown in the figure of the present invention, two flexible racks 511 are provided at both ends of the nose pad body 400, so as to be located at opposite sides of the nose pad opening 110, and respectively mesh with a first gear 512. In one embodiment, the two flexible racks 511 are symmetrically arranged on both sides of the nose pad opening 110. It can be understood that the power assembly 600 can drive the two first gears 512 to rotate in opposite directions. For the convenience of description, the nose pad body 400 is defined as having a first end and a second end, and the middle part of the nose pad body 400 is just opposite to the nose pad opening 110. One of the flexible racks 511 is provided at the first end and meshes with the first gear 512 at the first end. The power assembly 600 drives the first gear 512 at the first end to rotate clockwise, thereby driving the first end to move toward the nose pad opening 110. The other flexible rack 511 is provided at the second end and meshes with the first gear 512 at the second end. The power assembly 600 drives the first gear 512 at the second end to rotate counterclockwise, thereby driving the second end to move toward the nose pad opening 110. That is, the rotation directions of the two first gears 512 are opposite, so that the two ends of the nose pad body 400 are pushed and squeezed toward the middle at the same time, so that the middle area of ​​the nose pad body 400 is arched and protrudes from the nose pad opening 110 under the joint drive of the ejector 520 and the two first gears 512. In this way, the provision of the two flexible racks 511 and the two first gears 512 is conducive to the stability of the movement process of the nose pad body 400 protruding from the nose pad opening 110, and is also conducive to improving the efficiency of switching between the hidden state and the use state. The following description will be made by taking the case where two flexible racks 511 are provided as an example.

[0086] See also Figure 5 , Figure 8 and Fig. 9 In an embodiment of the present invention, the power assembly 600 includes a driving motor 610 disposed on the frame body 100 and electrically connected to the controller 910, a worm 620 disposed on the frame body 100, and a second gear 630 respectively connected to the worm 620 and the first gear 512, the worm 620 includes a first tooth area 621 meshing with the driving motor 610, and a second tooth area 622 meshing with the second gear 630, and the second gear 630 is coaxially arranged with the first gear 512.

[0087] Specifically, in the scheme shown in the figure of the present invention, the power assembly 600 includes a driving motor 610, a worm 620 and a second gear 630, wherein the driving motor 610 is electrically connected to the controller 910, and the controller 910 is used to control the operation of the driving motor 610, and the output shaft of the driving motor 610 is connected to the worm 620 in a transmission manner, thereby driving the worm 620 to rotate. The worm 620 is meshed with the second gear 630, thereby driving the second gear 630 to rotate. At the same time, the second gear 630 and the first gear 512 are coaxial gears, so that the first gear 512 also rotates, thereby driving the flexible rack 511 to move.

[0088] It can be understood that two flexible racks 511 are provided, and correspondingly, two first gears 512 are also provided. Two second gears 630 are also provided correspondingly, and the first gear 512 and the second gear 630 are coaxially arranged, that is, two coaxial gears composed of the first gear 512 and the second gear 630 are provided. More specifically, along the length direction of the worm 620, the worm 620 is provided with a second tooth area 622, a first tooth area 621 and a second tooth area 622 in sequence. Among them, the first tooth area 621 is meshed with the driving motor 610, and the two second tooth areas 622 are respectively meshed with the two second gears 630, thereby driving the first gear 512 to rotate and the flexible rack 511 to move in sequence. In this way, by providing a power member, the driving of the two first gears 512 can be achieved, which is conducive to the simplification of the structure of the power assembly 600 and the pusher 510, and is conducive to the lightweight of the smart glasses. In one embodiment, in order to ensure the normal rotation of the coaxial first gear 512 and the second gear 630 and avoid the influence of other structural parts on the rotation of the first gear 512 and the second gear 630, a gear cover plate 513 is provided on the first gear 512 and the second gear 630, and the gear cover plate 513 is connected to the frame body 100.

[0089] Of course, in other embodiments, the power assembly 600 may also be a cylinder, a hydraulic cylinder, etc., as long as it can drive the first gear 512 to rotate.

[0090] See also Figure 4 , Figures 12 to 16 In an embodiment of the present invention, the smart glasses further include a nose pad cover plate 300 disposed in the frame body 100, a positioning groove 310 corresponding to the nose pad opening 110 is disposed in the nose pad cover plate 300, and an ejector 520 includes a top block 521 movably disposed in the positioning groove 310, a permanent magnet 524 disposed at the top block 521 facing the bottom of the positioning groove 310, and an electromagnet 525 electrically connected to the controller 910, the electromagnet 525 and the permanent magnet 524 are disposed opposite to each other and have the same polarity.

[0091] Specifically, the nose pad cover plate 300 is arranged in the frame body 100, that is, the nose pad cover plate 300 is located in the receiving space, and the nose pad cover plate 300 is covered at the notch of the mounting groove 120, so that the nose pad body 400 is arranged between a side wall of the frame body 100 and the nose pad cover plate 300. In one embodiment, the frame body 100 is provided with a connecting hole at a position close to the mounting groove 120, and the nose pad cover plate 300 is also correspondingly provided with a connecting hole, and a connecting member such as a screw passes through the two connecting holes, so that the nose pad cover plate 300 and the frame body 100 are detachably connected. In this way, the collision of the nose pad body 400 is avoided, and the protection of the nose pad body 400 is improved. Of course, in other embodiments, the nose pad cover plate 300 and the frame body 100 can also be snap-connected, and the connection method between the two is not limited here.

[0092] See also Figure 4 and Fig.15 In one embodiment, the smart glasses further include a flexible circuit board 700, and the flexible circuit board 700 includes a main circuit board 710, an intermediate circuit board 720, and a nose pad circuit board 730, wherein the two ends of the intermediate circuit board 720 are electrically connected to the main circuit board 710 and the nose pad circuit board 730 respectively. More specifically, in one embodiment, a first connector 711 is provided on the main circuit board 710, and the intermediate circuit board 720 is electrically connected to the main circuit board 710 through the first connector 711. A second connector 721 is provided on the intermediate circuit board 720, and the nose pad circuit board 730 is electrically connected to the intermediate circuit board 720 through the second connector 721. In the scheme shown in the figure of the present invention, the controller 910 mentioned above is provided on the main circuit board 710, and the drive motor 610 is provided on the intermediate circuit board 720. In particular, in order to facilitate the transmission connection between the drive motor 610 and the worm 620, the intermediate circuit board 720 is provided with a first branch 722 for the drive motor 610 to be installed, so as to provide power to the drive motor 610.

[0093] In one embodiment, other electronic components, such as a pressure sensor, a bone conduction sensor, etc., are also provided on the nose pad circuit board 730. Taking the pressure sensor as an example, in one embodiment, the pressure sensor is electrically connected to the controller 910, and the pressure sensor is used to detect the pressure value when the nose pad body 400 contacts the nose bridge. When the pressure value reaches the first preset pressure, the nose pad body 400 reaches the first preset height. Here, there is no restriction on the first preset pressure.

[0094] In the scheme shown in the figure of the present invention, please refer to Figure 5 , Fig.17 and Fig.18The nose pad circuit board 730 is generally in a "U"-shaped structure, specifically including a first section 731, a bending section 732 and a second section 733 connected in sequence, wherein the first section 731 and the second section 733 are generally arranged in parallel. The first section 731 of the nose pad circuit board 730 is located in the nose pad body 400, the bending section 732 and part of the second section 733 are located in the mounting groove 120, and the other part of the second section 733 is located outside the nose pad cover 300. That is, after the first section 731 of the nose pad circuit board 730 passes through the bendable parts 410 and the non-bendable parts 420 one by one, it extends from one end of the nose pad body 400 and bends to form the bending section 732, and the second section 733 extends in the mounting groove 120 and passes through the nose pad cover 300. In one embodiment, in order to allow the second section 733 to extend out of the nose pad cover 300, a step portion 734 is formed on the second section 733, and a through hole is provided on the nose pad cover 300. The step portion 734 extends into the through hole and allows the free end of the second section 733 to pass through and be located above the nose pad cover 300.

[0095] See also Fig.12 , Fig.14 and Fig.16 The nose pad cover plate 300 is provided with a positioning groove 310 on the side facing the frame body 100. When the nose pad cover plate 300 is covered on the mounting groove 120, the positioning groove 310 corresponds to the position of the nose pad opening 110. The ejector 520 includes a top block 521, a permanent magnet 524 and an electromagnet 525. The top block 521 is movably arranged in the positioning groove 310, that is, the top block 521 can move relative to the positioning groove 310 to be used to abut or separate from the nose pad body 400. It can be understood that one end of the top block 521 is located at the notch end of the positioning groove 310 to abut the nose pad body 400. In one embodiment, in order to facilitate the nose pad body 400 to be ejected from the nose pad opening 110, one end of the top block 521 is provided with a top abutting tip. The other end of the top block 521 is located at the bottom end of the positioning groove 310, and the other end of the top block 521 is provided with a permanent magnet 524.

[0096] See also Fig.15 and Fig.16 In one embodiment, the electromagnet 525 is disposed on the middle circuit board 720 to be electrically connected to the controller 910, and the electromagnet 525 corresponds to the permanent magnet 524. More specifically, in order to facilitate the coordination between the electromagnet 525 and the permanent magnet 524, the middle circuit board 720 is provided with a second branch 723, and the second branch 723 is located above the side of the nose pad cover 300 away from the installation slot, and the electromagnet 525 is disposed on the second branch 723. In one embodiment, in order to facilitate the positioning and installation of the second branch 723, an electromagnetic slot 320 (such as Fig.11As shown in FIG. 3 , the electromagnetic slot 320 is used to accommodate the second branch 723, and the electromagnet 525 is disposed on the side of the second branch 723 facing the electromagnetic slot 320. Thus, the electromagnet 525 and the permanent magnet 524 are separated only by the nose support cover 300.

[0097] It can be understood that in one embodiment, the controller 910 is electrically connected to the electromagnet 525. When the nose pad body 400 needs to be ejected, the controller 910 controls the electromagnet 525 to be powered on, and the polarity of the electromagnet 525 and the permanent magnet 524 are the same, and the two repel each other. Under the action of the repulsive force, the permanent magnet 524 moves in a direction away from the electromagnet 525, thereby driving the top block 521 to move in a direction close to the nose pad opening 110, so that the top tip of the top block 521 contacts the nose pad body 400 and pushes against the nose pad body 400 to have a tendency to arch toward the nose pad opening 110. Under the push of the pusher 510, the nose pad body 400 has a tendency to protrude outward from the nose pad opening 110, and the bendable portion 410 bends, so that the nose pad body 400 protrudes from the nose pad opening 110. When the nose pad body 400 bulges outward from the nose pad opening 110 and breaks contact with the top block 521 , the controller 910 controls the electromagnet 525 to be powered off and lose polarity, thereby eliminating the repulsive force between the electromagnet 525 and the permanent magnet 524 , thereby canceling the supporting force of the top block 521 moving toward the nose pad opening 110 .

[0098] Of course, in other embodiments, the ejector 520 may also include an ejector block, a rotating shaft motor, a winding shaft, an adjustment rope, and an elastic member, wherein an elastic member is provided at the lower end of the ejector block, an adjustment rope is provided on the elastic member, one end of the adjustment rope is fixed to the elastic member, and the other end is wound on the winding shaft, and the winding shaft is connected to the rotating shaft motor in a transmission manner to rotate with the rotation of the rotating shaft motor. When the ejector 520 does not need to eject the nose pad body 400, the adjustment rope is wound on the winding shaft, so that the adjustment rope drives the elastic member to compress. When the ejector 520 needs to eject the nose pad body 400, the rotating shaft motor drives the winding shaft to rotate when it is working, and the adjustment rope is released from the winding shaft. With the release of the adjustment rope, the elastic member is released and stretched, so that the elastic member drives the ejector block to eject the nose pad body 400.

[0099] See also Fig.12 and Fig.13 In an embodiment of the present invention, a limiting hole 311 is provided on the side wall of the positioning groove 310, and a limiting pin 522 is provided on the top block 521. The limiting pin 522 extends into the limiting hole 311, and the limiting pin 522 can move along the limiting hole 311, so that the top block 521 can move relative to the positioning groove 310 and push the nose pad body 400 out of the nose pad opening 110.

[0100] Specifically, in the scheme shown in the figure of the present invention, a limit pin 522 is provided on the top block 521. In one embodiment, a mounting hole 523 is provided on the side wall of the top block 521, and the mounting hole 523 is arranged corresponding to the limit hole 311. The top block 521 is installed in the positioning groove 310, and then the limit pin 522 is passed through the limit hole 311 and the mounting hole 523 in sequence. The limit pin 522 is exactly matched with the mounting hole 523, that is, the limit pin 522 will not move in the mounting hole 523. Part of the limit pin 522 is exposed outside the mounting hole 523, and the limit pin 522 exposed outside the mounting hole 523 is located in the limit hole 311. In one embodiment, the outer surface of the limit pin 522 is flush with the outer surface of the side wall of the positioning groove 310. It can be understood that the aperture length of the limit hole 311 is greater than the outer diameter length of the limit pin 522, so that the limit pin 522 can move in the limit hole 311. The aperture length of the limiting hole 311 determines the maximum range of the ejection stroke of the ejector block 521. The aperture length of the limiting hole 311 can be set according to the needs and is not limited here. It is worth noting that the aperture length of the limiting hole 311 here refers to the length of the limiting hole 311 extending along the depth direction of the positioning groove 310.

[0101] It can be understood that when the electromagnet 525 is not powered on, the top block 521 contacts the bottom wall of the positioning groove 310, and at this time, the end of the top block 521 that is away from the bottom wall of the positioning groove 310 is located in the nose pad opening 110. When the controller 910 controls the electromagnet 525 to be powered on, a repulsive force is generated between the electromagnet 525 and the permanent magnet 524. Under the action of the repulsive force, the top block 521 moves in a direction away from the bottom wall of the positioning groove 310, that is, the top block 521 moves toward the inside of the smart glasses, thereby pushing the nose pad body 400 out of the nose pad opening 110. In one embodiment, at this time, the end of the top block 521 that is away from the bottom wall of the positioning groove 310 is located outside the nose pad opening 110, thereby ensuring that the top block 521 can push the nose pad body 400 out. When the nose pad body 400 bulges outward from the nose pad opening 110 and breaks away from the contact with the top block 521, the controller 910 controls the electromagnet 525 to be powered off and lose polarity, and can no longer push the permanent magnet 524 on the top block 521, and the top block 521 no longer continues to move toward the outside of the nose pad opening 110. When the nose pad module 200 is switched from the use state to the hidden state, the nose pad body 400 located outside the nose pad opening 110 moves into the nose pad opening 110 under the drive of the pusher 510. When the nose pad body 400 moves to contact with the top block 521, the top block 521 is not subjected to the repulsive force at this time. Driven by the nose pad body 400, the top block 521 also moves into the nose pad opening 110 until the nose pad body 400 is flat on the frame body 100.

[0102] See also Figure 3 , Figure 6 , Fig.17 and Fig.18In an embodiment of the present invention, an expansion membrane 430 is further provided on the nose pad body 400, and the expansion membrane 430 can at least protrude from the side of the nose pad body 400 close to the bridge of the nose. The adjustment component 500 also includes an inflation component 800 electrically connected to the controller 910. In use, the controller 910 controls the inflation component 800 to inflate the expansion membrane 430.

[0103] Specifically, the nose pad body 400 is bendable and also has an expansion membrane 430, which can expand and bulge toward the direction close to the bridge of the nose, so that the distance between the left nose pad and the right nose pad can be adjusted, that is, the distance between the nose pad body 400 and the bridge of the nose in the left and right directions of the bridge of the nose can be adjusted, so that the smart glasses can be adapted to nose bridges of different widths, thereby improving the applicability of the smart glasses.

[0104] The adjustment component 500 also includes an inflation component 800 electrically connected to the controller 910. When the nose pad body 400 protrudes from the nose pad opening 110, the controller 910 controls the inflation component 800 to operate. When the inflation component 800 is inflated, the expansion membrane 430 begins to expand and protrude toward the side close to the bridge of the nose, thereby adjusting the distance between the nose pad body 400 and the bridge of the nose.

[0105] Of course, in other embodiments, the expansion membrane 430 can expand and bulge toward the side close to the bridge of the nose, and can also expand and bulge toward other directions, which is not limited here. It can be understood that the expansion membrane 430 is mainly provided to adjust the distance between the nose pad body 400 and the bridge of the nose. The following is an example in which the expansion membrane 430 can only expand and bulge toward the side close to the bridge of the nose.

[0106] In one embodiment, the expansion membrane 430 is disposed on the non-bendable portion 420. An air cavity 422 is formed in the non-bendable portion 420, and at least part of the inflatable component 800 is located in the air cavity. The expansion membrane 430 is configured as the cavity wall of the air cavity 422 on the side facing the bridge of the nose. It can be understood that other areas of the non-bendable portion 420 cannot be deformed, and only the expansion membrane 430 can be deformed to expand or retract under the drive of the inflatable component 800. In this way, the expansion membrane 430 can accurately expand only in the direction of the bridge of the nose, thereby avoiding the expansion membrane 430 from expanding in other directions while expanding in the direction of the bridge of the nose, thereby avoiding the extra energy consumption of the inflatable component 800, which is beneficial to improving the efficiency of the inflatable component 800.

[0107] It can be understood that the nose pad body 400 includes a plurality of non-bendable parts 420 and bendable parts 410. When the smart glasses are worn, only some of the non-bendable parts 420 and bendable parts 410 in the nose pad body 400 are in contact with the bridge of the nose. In one embodiment, the expansion membrane 430 is only provided on the six non-bendable parts 420 in the middle part of the nose pad body 400. In this way, the extra energy consumption of the inflatable component 800 is avoided. Of course, the number of expansion membranes 430 can be set according to actual needs and is not limited here.

[0108] The expansion membrane 430 is arranged on the non-bendable part 420. When the expansion membrane 430 expands, the expansion membrane 430 on the adjacent non-bendable part 420 expands at the same time, and the expansion area 421 is not arranged on the bendable part 410. The location of the bendable part 410 provides an expansion space for the expansion of the expansion membrane 430. At the same time, it can be understood that the bendable part 410 is made of a deformable material. If the expansion membrane 430 is arranged on the bendable part 410, when the inflatable component 800 is working, the area on the bendable part 410 where the expansion membrane 430 is not arranged will also expand and deform, which is not conducive to the control of the expansion direction.

[0109] It can be understood that the adjustment component 500 can adjust the distance between the nose support module 200 and the nose bridge along the front-back direction of the line of sight, and the inflatable component 800 can adjust the distance between the nose support module 200 and the nose bridge along the left-right direction of the nose bridge. In this way, in one embodiment, the height of the smart glasses can be adjusted by the cooperation of the adjustment component 500 and the inflatable component 800. Of course, in other embodiments, the height of the smart glasses can also be adjusted only by the adjustment component 500 or the inflatable component 800.

[0110] In an embodiment of the present invention, the nose pad module 200 includes an expansion membrane 430. In a hidden state, the expansion membrane 430 is in a contracted state and does not protrude from the plane where the nose pad opening 110 is located; the adjustment component 500 also includes an inflation component 800 electrically connected to the controller 910. In a use state, the controller 910 inflation component 800 inflates the expansion membrane 430 so that at least part of the expansion membrane 430 protrudes out of the nose pad opening 110.

[0111] Specifically, in one embodiment, the nose support module 200 does not include a bendable nose support body 400, but realizes the switching between the hidden state and the use state through the expansion membrane 430. At the same time, the adjustment component 500 includes an inflatable component 800, and the inflatable component 800 is used to control the expansion and contraction of the expansion membrane 430. More specifically, when the nose support module 200 is in the hidden state, the controller 910 controls the inflatable component 800 not to inflate the expansion membrane 430, the expansion membrane 430 is in a contracted state, and the expansion membrane 430 does not protrude from the plane where the nose support opening 110 is located. When the nose support module 200 is in the use state, the controller 910 controls the inflatable component 800 to inflate the expansion membrane 430, and the expansion membrane 430 begins to expand and is squeezed out from the frame body 100 through the nose support opening 110, so that the expansion membrane 430 protrudes from the nose support opening 110 to contact the bridge of the nose. When the nose pad module 200 switches from the use state to the hidden state, the controller 910 controls the inflation component 800 to evacuate the expansion membrane 430, so that the expansion membrane 430 shrinks and retracts into the nose pad opening 110. In this way, only the expansion membrane 430 is provided in the nose pad module 200, and the switching between the hidden state and the use state can be achieved by adjusting the inflation component 800. It is worth noting that in this embodiment, the expansion membrane 430 can at least protrude from the nose pad opening 110, that is, in this embodiment, the expansion membrane 430 has at least a convex deformation in the front and rear direction of the line of sight.

[0112] See also Figure 4 and Fig.18 In an embodiment of the present invention, the inflation assembly 800 includes an inflation / deflation motor 810 and an air duct 820 . The inflation / deflation motor 810 is disposed on the frame body 100 , and the air duct 820 connects the expansion membrane 430 with the inflation / deflation motor 810 .

[0113] Specifically, the following description is made by taking the nose pad module 200 as an example in which the nose pad module 200 does not include the bendable nose pad body 400 but includes the expansion membrane 430. When the controller 910 controls the inflation motor 810 to inflate the expansion membrane 430 through the air duct 820, the expansion membrane 430 protrudes from the nose pad opening 110, so that the nose pad module 200 is in use. When the controller 910 controls the inflation motor 810 to deflate the expansion membrane 430 through the air duct 820, the expansion membrane 430 shrinks and retracts into the nose pad opening 110, so that the nose pad module 200 is in a hidden state.

[0114] The following is an example of a nose pad body 400 including a bendable portion 410, a non-bendable portion 420 and an expansion membrane 430. Specifically, in the scheme shown in the figure of the present invention, the charging and discharging motor 810 is arranged on the second branch 723 of the intermediate circuit board 720 to provide power for the charging and discharging motor 810. The air duct 820 is roughly in a "U"-shaped structure. In one embodiment, the air duct 820 is arranged side by side with the nose pad circuit board 730. After passing through the bendable portion 410 and the non-bendable portion 420 one by one, the air duct 820 is bent and extends in the mounting groove 120 and then passes through the nose pad cover 300. Among them, the end of the air duct 820 located in the nose pad body 400 is a closed end, and the end of the air duct 820 extending out of the nose pad cover 300 is an open end, and the open end is connected to the charging and discharging motor 810. It can be understood that the air guide tube 820 is configured with a flexible material so that the air guide tube 820 can bulge outward along with the nose pad body 400 .

[0115] In one embodiment, both the non-bendable portion 420 and the bendable portion 410 are configured as cavity structures, which is beneficial to the lightweight of the nose pad body 400. In one embodiment, adjacent cavity structures are independent of each other. The nose pad circuit board 730 and the air duct 820 are arranged in the cavity structures of the non-bendable portion 420 and the bendable portion 410. Specifically, the non-bendable portion 420 is formed with an air accommodating cavity 422, and the air duct 820 is provided with an air duct hole 821 in the air accommodating cavity 422, that is, the gas in the air duct 820 can enter the air accommodating cavity 422 through the air duct hole 821. In other words, each air accommodating cavity 422 can only be connected through the air duct hole 821 on the air duct 820.

[0116] It can be understood that, in one embodiment, the charging and discharging motor 810 is electrically connected to the controller 910. When it is necessary to reduce the distance between the nose support module 200 and the bridge of the nose, the controller 910 controls the charging and discharging motor 810 to inflate, and the gas enters the corresponding air chamber 422 through the air holes 821 on the air tube 820. As the inflation proceeds, the expansion area 421 begins to expand, so that the nose support body 400 is close to the bridge of the nose. When it is necessary to increase the distance between the nose support module 200 and the bridge of the nose, the controller 910 controls the charging and discharging motor 810 to deflate, and the gas in the air chamber 422 is drawn into the air tube 820 through the air holes 821 and discharged from the air chamber 422, so that the expansion area 421 retracts, so that the nose support module 200 is away from the bridge of the nose.

[0117] Of course, in other embodiments, the inflation component 800 may also be an inflation button and a push rod, one end of the push rod is connected to the inflation button, and the other end is connected to the inflation membrane 430. When the inflation button is pressed, the push rod is forced to move and push the inflation membrane 430 to move toward the direction close to the bridge of the nose, thereby adjusting the distance between the nose support module 200 and the bridge of the nose.

[0118] It is understandable that the expansion membrane 430 itself is elastic, and it can be elastically deformed when subjected to external force, and can recover the deformation after the external force is lost, so that the expansion membrane 430 can expand or retract when the inflation or deflation motor 810 is inflated or deflated. In one embodiment, the expansion membrane 430 is made of thermoplastic resins such as polyethylene or polypropylene through a special process. It is understandable that when wearing smart glasses, the expansion membrane 430 is used to contact the bridge of the nose, and the soft properties of the expansion membrane 430 can improve the wearing comfort of the smart glasses. Of course, in other embodiments, the expansion membrane 430 can also be made of latex.

[0119] In an embodiment of the present invention, when the nose pad module 200 only includes the bendable nose pad body 400, the controller 910 controls the adjustment component 500 to bend the nose pad body 400 according to the nose pad adjustment signal when receiving the nose pad adjustment signal, and bends the nose pad body 400 to a first preset height protruding relative to the nose pad opening 110; or,

[0120] When the nose pad module 200 includes a bendable nose pad body 400 and an expansion membrane 430 disposed on the nose pad body 400, the controller 910 controls the adjustment component 500 to first bend the nose pad body 400 according to the nose pad adjustment signal, and bends it to a first preset height relative to the nose pad opening 110, and then controls the inflation component 800 to inflate the expansion membrane 430, so that the expansion membrane 430 is inflated to a second preset height relative to the side of the nose pad body 400 close to the bridge of the nose; or,

[0121] When the nose pad module 200 only includes the expansion membrane 430 , upon receiving a nose pad adjustment signal, the controller 910 controls the inflation component 800 to inflate the expansion membrane 430 according to the nose pad adjustment signal, so that the expansion membrane 430 expands to a first preset height relative to the nose pad opening 110 .

[0122] It can be understood that the controller 910 is electrically connected to both the adjustment component 500 and the inflation component 800, that is, the controller 910 can control the operation of the adjustment component 500 and the inflation component 800 according to the received nose pad adjustment signal. The nose pad adjustment signal can be issued by an electrical device installed in the frame body 100 and electrically connected to the controller 910, such as a distance sensor 920, a pressure sensor, etc., which are not limited here. The first preset height refers to the height along the front-to-back direction of the line of sight after wearing the smart glasses; the second preset height refers to the height along the left-to-right direction of the bridge of the nose after wearing the smart glasses. The specific height values ​​or height ranges of the first preset height and the second preset height can be set according to needs, and are not limited here.

[0123] In this way, the height of the smart glasses can be controlled solely by the protruding height of the nose pad body 400 (i.e., the first preset height); or, it can be controlled jointly by the protruding height of the nose pad body 400 (i.e., the first preset height) and the protruding height of the expansion membrane 430 (i.e., the second preset height); or, it can also be controlled solely by the bulging height of the expansion membrane 430 (i.e., the first preset height).

[0124] In an embodiment of the present invention, a distance sensor 920 electrically connected to the controller 910 is also provided on the frame body 100. The distance sensor 920 is used to detect the distance between the frame body 100 and the bridge of the nose, and transmit the distance signal to the controller 920. The controller 920 generates a nose pad adjustment signal based on the distance signal.

[0125] Specifically, taking the nose pad module 200 including the bendable nose pad body 400 as an example, refer to Figure 4 , a distance sensor 920 electrically connected to the controller 910 is provided on the frame body 100. When the smart glasses are worn, the distance sensor 920 is used to detect the distance between the frame body 100 and the bridge of the nose. When the detected distance signal value is less than the predetermined distance range value, the controller 910 controls the adjustment component 500 to work, thereby driving the nose pad body 400 to bulge outward until the nose pad body 400 bulges outward to a first preset height. In this embodiment, the distance sensor 920 detects whether the smart glasses have been worn in place. When the distance sensor 920 detects that the smart glasses have been worn in place, the controller 910 controls the adjustment component 500 to make the nose pad body 400 bulge outward. It is worth noting that the predetermined distance range value can be set according to actual conditions, and is not limited here. In this way, by setting the controller 910 and the distance sensor 920, the automation of the use of the smart glasses is improved.

[0126] In one embodiment, the distance sensor 920 can be configured as an infrared distance sensor 920 or a proximity sensor, and the type of the distance sensor 920 is not limited here. In one embodiment, the distance sensor 920 is arranged on the nose bridge of the frame body 100, specifically on the side of the nose bridge facing below the line of sight, which is conducive to the reliability of the detected distance signal value. Of course, the distance sensor 920 can also be arranged at other positions of the frame body 100, which is not limited here.

[0127] The control component also includes an adjustment button 930 disposed on the frame body 100 , and the adjustment button 930 is used to control the operation of the adjustment component 500 .

[0128] Specifically, see Fig.10The frame body 100 of the smart glasses is also provided with an adjustment button 930. When the hidden state and the use state of the nose pad module 200 need to be switched, the adjustment button 930 can be pressed to control the operation of the adjustment component 500. In this way, the state of the nose pad module 200 can be adjusted before or after wearing the smart glasses, thereby improving the diversity of use of the smart glasses. In one embodiment, in order to facilitate pressing the adjustment button 930, the adjustment button 930 is arranged on the temple of the frame body 100, and can be specifically arranged at one end of the temple close to the mirror ring. Of course, the adjustment button 930 can also be arranged at other positions of the frame body 100, which is not limited here.

[0129] In other embodiments, the smart glasses are provided with both a distance sensor 920 and an adjustment button 930. When preparing to wear the smart glasses, the adjustment button 930 is pressed to make the nose pad body 400 protrude to a third preset height, and then the smart glasses are worn on the bridge of the nose. At this time, the distance sensor 920 starts to detect the distance between the nose pad body 400 and the bridge of the nose, so that the controller 910 determines and adjusts the protruding height of the nose pad body 400, and adjusts the nose pad body 400 to the first preset height, so that the smart glasses can be worn at the same height above the bridge of the nose every time.

[0130] It is worth noting that in this embodiment, the distance sensor 920 detects the distance between the nose pad body 400 protruding from the nose pad opening 110 and the nose bridge. Generally, the third preset height is close to the height value of the first preset height, and the difference between the third preset height and the first preset height is not limited here.

[0131] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
