Description

Technical Field

[0001] This invention relates to the field of smart wearable technology, and in particular to a smart pair of glasses. Background Technology

[0002] Eyeglasses generally consist of a frame, lenses, and temples. For comfortable wear, nose pads are typically provided where the frame contacts the bridge of the nose. Generally, a nose pad opening is provided in the frame for attaching the nose pads.

[0003] Currently, in existing eyeglasses, the nose pads are generally fixed to the inside of the frame. However, this fixed connection makes it easy for dust to accumulate on the nose pads when the glasses are not in use, and they are also prone to damage in case of accidents. Summary of the Invention

[0004] The main objective of this invention is to provide a smart glasses solution that improves the protection of the nose pad module within the smart glasses, thereby enhancing the overall protection of the smart glasses.

[0005] To achieve the above objectives, the smart glasses proposed in this embodiment of the invention include:

[0006] The frame itself has a nose pad opening;

[0007] A nose pad module has a hidden state and a used state. In the hidden state, the nose pad module does not protrude from the plane of the nose pad opening; in the used state, the nose pad module protrudes from the nose pad opening to contact the bridge of the nose.

[0008] The control component includes a controller and an adjustment component electrically connected to the controller, the controller being used to switch the hidden state and the used state via the adjustment component.

[0009] In one embodiment, the nose pad module includes a bendable nose pad body. In the hidden state, the nose pad body is laid flat within the frame body. In the use state, the adjustment component is used to bend the nose pad body and arch it toward the nose pad opening, so that at least a portion of the nose pad body protrudes from the nose pad opening.

[0010] In one embodiment, the nose pad body includes a bendable portion and a non-bendable portion connected together; the adjustment assembly includes a pusher and an ejector opposite to the nose pad opening, the pusher driving the nose pad body to move toward the nose pad opening, while the ejector pushing the nose pad body toward the outside of the nose pad opening, so that the bendable portion at the nose pad opening bends, so that under the push of the pusher, the non-bendable portion and the bent bendable portion protrude from the nose pad opening.

[0011] In one embodiment, the adjustment assembly further includes a power assembly electrically connected to the controller, the pusher including a meshing first gear and a flexible rack, the flexible rack being disposed on the nose pad body, and the power assembly being used to drive the first gear to rotate.

[0012] In one embodiment, the power assembly includes a drive motor disposed on the frame body and electrically connected to the controller, a worm gear disposed on the frame body, and a second gear that is respectively drivenly connected to the worm gear and the first gear. The worm gear includes a first tooth region that meshes with the drive motor and a second tooth region that meshes with the second gear. The second gear is coaxially arranged with the first gear.

[0013] In one embodiment, the smart glasses further includes a nose pad cover plate disposed within the frame body. The nose pad cover plate has a positioning groove corresponding to the nose pad opening. The ejector includes a top block movably disposed in the positioning groove, a permanent magnet disposed on the bottom of the top block facing the positioning groove, and an electromagnet electrically connected to the controller. The electromagnet and the permanent magnet are disposed opposite to each other and have the same polarity.

[0014] In one embodiment, the positioning groove has a limiting hole on its sidewall, and the top block has a limiting pin. The limiting pin extends into the limiting hole and can move along the limiting hole, so that the top block can move relative to the positioning groove and push the nose pad body out of the nose pad opening.

[0015] In one embodiment, the nose pad body is further provided with an expansion film, the expansion film being at least protruding from the side of the nose pad body near the bridge of the nose, and the adjustment assembly further includes an inflation assembly electrically connected to the controller, wherein in the use state, the controller controls the inflation assembly to inflate the expansion film.

[0016] In one embodiment, the nose pad module includes an expansion film, which is in a contracted state in the hidden state and does not protrude from the plane of the nose pad opening; the adjustment assembly further includes an inflation assembly electrically connected to the controller, which in the use state inflates the expansion film by the inflation assembly to make at least a portion of the expansion film protrude from the nose pad opening.

[0017] In one embodiment, when the nose pad module only includes a bendable nose pad body, when the controller receives a nose pad adjustment signal, it controls the adjustment component to bend the nose pad body according to the nose pad adjustment signal, and bends it to protrude a first preset height relative to the nose pad opening; or

[0018] When the nose pad module includes a bendable nose pad body and an expansion film disposed on the nose pad body, when the controller receives a nose pad adjustment signal, it controls the adjustment component to first bend the nose pad body until it protrudes a first preset height relative to the nose pad opening, and then controls the inflation component to inflate the expansion film so that the expansion film expands to protrude a second preset height relative to the side of the nose pad body near the bridge of the nose; or

[0019] When the nose pad module only includes an expansion film, when the controller receives a nose pad adjustment signal, it controls the inflation component to inflate the expansion film according to the nose pad adjustment signal, so that the expansion film expands to protrude a first preset height relative to the nose pad opening.

[0020] In one embodiment, the frame body is further provided with a distance sensor electrically connected to the controller. The distance sensor is used to detect the distance between the frame body and the bridge of the nose and transmit the distance signal to the controller. The controller generates the nose pad adjustment signal based on the distance signal.

[0021] In one embodiment, the control component further includes an adjustment button disposed on the frame body, the adjustment button being used to control the operation of the adjustment component.

[0022] In one embodiment, the inflation assembly includes an inflation / deflation motor and an air guide tube. The inflation / deflation motor is located on the frame body, and the air guide tube connects the inflation membrane and the inflation / deflation motor.

[0023] The technical solution of this invention provides smart glasses by incorporating a frame body, a nose pad module, and a control component. The frame body has a nose pad opening, and the nose pad module has a hidden state and a used state. In the hidden state, the nose pad module is located within the nose pad opening; in the used state, the nose pad module protrudes from the nose pad opening to contact the bridge of the nose. The control component includes a controller and an adjustment component electrically connected to the controller. The controller switches between the hidden state and the used state via the adjustment component. Thus, the nose pad module is configured with two states: when the smart glasses are in use, the nose pad module protrudes from the nose pad opening; when the smart glasses are not in use, the nose pad module is located within the nose pad opening. This avoids accidental collisions to the nose pad module when the smart glasses are not in use, improving the protection of the nose pad module and consequently, the protection of the smart glasses. Simultaneously, by controlling the adjustment component through the controller to switch between the hidden and used states of the nose pad module, the automation and intelligence of the smart glasses are improved, enhancing the user experience.

[0054] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0055] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0056] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0057] Eyeglasses generally consist of a frame, lenses, and temples. For comfortable wear, nose pads are typically provided where the frame contacts the bridge of the nose. Generally, a nose pad opening is provided in the frame for attaching the nose pads.

[0058] Currently, in existing eyeglasses, the nose pads are generally fixed to the inside of the frame. However, this fixed connection makes it easy for dust to accumulate on the nose pads when the glasses are not in use, and they are also prone to damage in case of accidents.

[0059] This invention proposes a smart glasses.

[0060] Please see 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 used 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 used 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 between the hidden state and the used state through the adjustment component 500.

[0061] Understandably, the frame body 100 includes two temples for resting on the ears to facilitate wearing the smart glasses. For ease of explanation, the side of the frame body 100 with the temples is defined as the inner side of the smart glasses, and the side opposite the temples is defined as the outer side of the smart glasses. In one embodiment, the smart glasses also include an optical module mounted on the frame body 100.

[0062] The frame body 100 has 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, which hides the nose pad module 200 inside the nose pad opening 110. That is, the nose pad module 200 does not protrude from the side of the frame body 100 facing the smart glasses; at this time, 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, which causes the nose pad module 200 to protrude from the nose pad opening 110 to contact the bridge of the nose, thus facilitating the wearing of the smart glasses; at this time, the nose pad module 200 is in use. Thus, when the smart glasses are in use, the nose pad module 200 protrudes from the nose pad opening 110 and contacts the bridge of the nose, 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 inside the nose pad opening 110, thereby avoiding accidental collisions to the nose pad module 200, improving the protection of the nose pad module 200, and thus improving the protection of the smart glasses. It also prevents dust accumulation on the nose pad module 200, making it easier to clean the smart glasses.

[0063] Understandably, the nose pad module 200 includes a left nose pad and a right nose pad, for contacting the left and right sides of the bridge of the nose, respectively. Correspondingly, the frame body 100 also has two nose pad openings 110 for mounting the left and right nose pads, respectively.

[0064] The technical solution of this invention involves incorporating a frame body 100, a nose pad module 200, and a control component into smart glasses. The frame body 100 has a nose pad opening 110, and the nose pad module 200 has a hidden state and a used state. In the hidden state, the nose pad module 200 is located within the nose pad opening 110; in the used state, the nose pad module 200 protrudes beyond 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 switches between the hidden state and the used state via the adjustment component 500. Thus, the nose pad module 200 is configured in two states: when using the smart glasses, the nose pad module 200 protrudes beyond the nose pad opening 110; when not using the smart glasses, the nose pad module 200 is located within the nose pad opening 110. This avoids accidental collisions to the nose pad module 200 when the smart glasses are not in use, improving the protection of the nose pad module 200 and thus the protection of the smart glasses. Simultaneously, the controller 910 controls the adjustment component 500 to switch between the hidden and active states of the nose pad module 200, thereby improving the automation and intelligence of the smart glasses and enhancing the user experience.

[0065] Please see Figures 4 to 6In an embodiment of the present invention, the nose pad module 200 includes a bendable nose pad body 400. In a hidden state, the nose pad body 400 is laid flat inside the frame body 100. In the 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 outward from the nose pad opening 110.

[0066] Specifically, in the embodiment shown in the figures of this invention, the nose pad module 200 includes a bendable nose pad body 400. It is understood that the nose pad body 400 may be partially or entirely bendable. No limitation is made here.

[0067] When the nose pad module 200 is in the hidden state, the nose pad body 400 lies flat inside the frame body 100. It is understood that the frame body 100 is a hollow structure, with an internal storage space for mounting various structural components. In the hidden state, the nose pad body 400 is located within this storage space and lies flat on the frame body 100.

[0068] Understandably, a nose pad opening 110 is formed on one side wall of the frame body 100 facing the inside of the smart glasses. In one embodiment, in the hidden state, at least a portion of the nose pad body 400 covers the nose pad opening 110. At this time, if viewed from the inside of the smart glasses, a portion of the nose pad body 400 can be seen from the nose pad opening 110, and the nose pad body 400 does not protrude beyond the receiving space of the frame body 100. This avoids the exposure of other structural components within the receiving space of the frame body 100, prevents damage to other structures within the frame body 100, and also contributes to the aesthetics of the smart glasses in the hidden state.

[0069] When the nose pad module 200 is in use, the nose pad body 400 bends under the adjustment of the adjustment component 500, causing the nose pad body 400 to arch towards the nose pad opening 110 and protrude outward from the nose pad opening 110. Here, there are no restrictions on the size of the nose pad opening 110 or 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 have a flat shape, but rather 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 retracts directly into the nose pad opening 110 under the adjustment of the adjustment component 500; when the smart glasses are in use, the nose pad body 400 extends directly outward and protrudes from the nose pad opening 110 under the adjustment of the adjustment component 500.

[0071] Please see Figures 4 to 6 , Figure 10 and Figure 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. The adjustment assembly 500 includes a pusher 510 and an ejector 520 opposite to the nose pad opening 110. The pusher 510 drives the nose pad body 400 to move toward the nose pad opening 110, while the ejector 520 pushes 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 bends, so that under the push of the pusher 510, the non-bendable portion 420 and the bent bendable portion 410 protrude from the nose pad opening 110.

[0072] Specifically, the frame body 100 has a mounting groove 120, and the nose pad body 400 is disposed within the mounting groove 120. Thus, the mounting groove 120 provides guidance and a mounting position for the nose pad body 400. The nose pad body 400 includes a bendable portion 410 and a non-bendable portion 420. Under the adjustment of the adjusting component 500, both the bendable portion 410 and the non-bendable portion 420 can protrude from the nose pad opening 110 and contact the bridge of the nose. The non-bendable portion 420 improves the morphological stability of the nose pad body 400 in use.

[0073] In the embodiment shown in the figures of this invention, the nose pad body 400 includes a plurality of bendable portions 410 and a plurality of non-bendable portions 420, wherein one bendable portion 410 and one non-bendable portion 420 are arranged adjacent to each other. That is, the nose pad body 400 is designed with a segmented structure. This segmented structure improves the ease of switching between a concealed state and a use state for the nose pad body 400. Simultaneously, the arrangement of multiple bendable portions 410 and multiple non-bendable portions 420 further improves the morphological stability of the nose pad body 400 in the use state. The number of bendable portions 410 and non-bendable portions 420 is not limited here.

[0074] Please see Figure 5 The adjustment component 500 includes a pusher 510 and an ejector 520. When the nose pad module 200 switches from a hidden state to a used state, the pusher 510 moves the nose pad body 400, which is laid flat on the frame body 100, 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 pushes the nose pad body 400 toward the inside of the smart glasses, thereby causing the bendable portion 410 to bend, so that the nose pad body 400 moving toward the nose pad opening 110 can protrude from the nose pad opening 110. As the pusher 510 continues to push, the nose pad body 400 continues to protrude toward the outside of the nose pad opening 110 until the nose pad body 400 reaches a first preset height. It is worth noting that the first preset height refers to the height extended along the front-to-back direction of the line of sight after the smart glasses are worn. The first preset height can be set according to needs, and there is no limitation on the first preset height here.

[0075] When the nose pad module 200 is switched from the use state to the hidden state, the pusher 510 drives the part of the nose pad body 400 that is still in the nose pad opening 110 to move away from the nose pad opening 110. Understandably, the ejector 520 does not work at this time, that is, the ejector 520 no longer ejects the nose pad body 400. Thus, under the action of the pusher 510, the protruding nose pad body 400 can retract into the nose pad opening 110 and lie flat in the frame body 100.

[0076] Understandably, to ensure that the non-bendable portion 420 and the bent portion 410 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 bent 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 the same as the width of the bent portion 410 to facilitate the forming of the nose pad body 400. Furthermore, the widths of both the non-bendable portion 420 and the bent portion 410 are slightly smaller than the width of the nose pad opening 110. This avoids the exposure of the structural components inside the nose pad opening 110 when viewed from the inside of the smart glasses; at the same time, it also ensures that the non-bendable portion 420 and the bent portion 410 can protrude from the nose pad opening 110. It is worth noting that "slightly smaller" refers to a slightly smaller size in the conventional sense; in one embodiment, the difference can be within the range of 0.2 mm. 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 is not limited here. The length of the non-bendable portion 420 is greater than the length of the bendable portion 410, thus ensuring the structural strength of the nose pad body 400 after it protrudes from the nose pad opening 110, that is, ensuring the structural strength of the nose pad body 400 when the nose pad module 200 is in use. The lengths of both the non-bendable portion 420 and the bendable portion 410 are less than the length of the nose pad opening 110, thus ensuring that the nose pad body 400 can protrude from the nose pad opening 110. In one embodiment, as... 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 restrictions are placed on the dimensions 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 made of materials such as silicone or rubber, and the non-bendable portion 420 is made of materials such as rigid plastic or sheet metal. No specific material is limited for the bendable portion 410 and the non-bendable portion 420.

[0078] Of course, in other embodiments, the nose pad body 400 may only include a bendable portion 410. Under the adjustment of the adjusting component 500, the bendable portion 410 can 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. This ensures that the bendable portion 410 can be bent and deformed to protrude outward from the nose pad opening 110, while also ensuring the morphological stability of the bendable portion 410 in use. More specifically, in one embodiment, the adjusting component 500 may be a telescopic device. When the telescopic device extends, it causes the bendable portion 410 to protrude outward from the nose pad opening 110. When the telescopic device retracts, it causes the bendable portion 410 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 corresponding to the nose pad opening 110, and the end of the telescopic push rod away from the motor connected to the nose pad body 400. When the nose pad body 400 needs to be pushed out, the motor operates, thereby driving the telescopic push rod to extend and causing 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, thereby causing the nose pad body 400 to retract into the nose pad opening 110. In this way, the nose pad body 400 can also be hidden and used.

[0080] Please see Figures 6 to 9 In an embodiment of the present invention, the adjustment component 500 further 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 disposed on the nose pad body 400. The power component 600 is used to drive the first gear 512 to rotate.

[0081] Specifically, in the embodiment shown in the figures of this invention, the pushing member 510 includes a meshing first gear 512 and a flexible rack 511. 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 made of a flexible material, so that the flexible rack 511 has a certain deformation capability. Thus, when the bendable portion 410 is bent, the flexible rack 511 can also bend accordingly, thereby not affecting the bending effect of the bendable portion 410, and can protrude outward from the nose pad opening 110 along with the nose pad body 400. When the nose pad body 400 is laid flat inside the frame body 100 and the bendable portion 410 is not bent, the flexible rack 511 can also return to its original shape without affecting its meshing with the first gear 512. In one embodiment, the flexible rack 511 is configured to be made of materials such as silicone or rubber.

[0082] The first gear 512 is installed inside the frame body 100. In one embodiment, the mounting groove 120 has a gear mounting position on its groove wall. The first gear 512 is installed in the gear mounting position, allowing it to rotate relative to the gear mounting position. Thus, when the nose pad module 200 switches from a hidden state to a used state, the controller 910 controls the power component 600 to operate, causing the power component 600 to drive the first gear 512 to rotate. This causes the flexible rack 511 to move relative to the first gear 512, thereby moving the nose pad body 400 toward the nose pad opening 110. At the same time, the ejector 520 operates, pushing the nose pad body 400 at the nose pad opening 110 outwards, that is, pushing the nose pad body 400 at the nose pad opening 110 toward the inside of the smart glasses. This causes the bendable portion 410 to bend, allowing the nose pad body 400 to protrude from the nose pad opening 110 under the action of the flexible rack 511. When the nose pad module 200 is switched from the used state to the hidden state, the power component 600 only needs to drive the first gear 512 to rotate in the opposite direction. The specific movement process will not be described in detail.

[0083] Of course, in other embodiments, the pusher 510 can also be a push rod and a push motor. The push motor is electrically connected to the controller 910 and is mounted 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, there are two push rods, which are respectively located at both ends of the nose pad body 400 along its length. 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] Please see Figure 5 and Figure 9 In an embodiment of the present invention, two flexible racks 511 are provided, which are respectively provided at both 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 meshes with one flexible rack 511.

[0085] Specifically, in the embodiment shown in the figures of this invention, two flexible racks 511 are disposed at both ends of the nose pad body 400, respectively located on opposite sides of the nose pad opening 110, and each meshes 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 is understood that the power assembly 600 can drive the two first gears 512 to rotate in opposite directions. For ease of explanation, the nose pad body 400 is defined to have a first end and a second end, with the middle portion of the nose pad body 400 directly opposite the nose pad opening 110. One flexible rack 511 is located at the first end and meshes with the first gear 512 at the first end. The power component 600 drives the first gear 512 at the first end to rotate clockwise, thereby moving the first end toward the nose pad opening 110. The other flexible rack 511 is located at the second end and meshes with the first gear 512 at the second end. The power component 600 drives the first gear 512 at the second end to rotate counterclockwise, thereby moving the second end toward the nose pad opening 110. That is, the two first gears 512 rotate in opposite directions, which simultaneously pushes and compresses both ends of the nose pad body 400 toward the middle, causing the middle area of ​​the nose pad body 400 to arch and protrude out of the nose pad opening 110 under the combined drive of the ejector 520 and the two first gears 512. Thus, the arrangement of the two flexible racks 511 and the two first gears 512 is beneficial to the stability of the movement process of the nose pad body 400 protruding out of the nose pad opening 110, and also helps to improve the efficiency of switching between the hidden state and the use state. The following explanation will be based on the example of two flexible racks 511.

[0086] Please see Figure 5 , Figure 8 and Figure 9 In an embodiment of the present invention, the power assembly 600 includes a drive motor 610 disposed on the frame body 100 and electrically connected to the controller 910, a worm gear 620 disposed on the frame body 100, and a second gear 630 that is respectively drivenly connected to the worm gear 620 and the first gear 512. The worm gear 620 includes a first tooth region 621 that meshes with the drive motor 610 and a second tooth region 622 that meshes with the second gear 630. The second gear 630 is coaxially arranged with the first gear 512.

[0087] Specifically, in the embodiment shown in the figures of this invention, the power assembly 600 includes a drive motor 610, a worm gear 620, and a second gear 630. The drive motor 610 is electrically connected to a controller 910, which controls the operation of the drive motor 610. The output shaft of the drive motor 610 is connected to the worm gear 620, thereby driving the worm gear 620 to rotate. The worm gear 620 meshes with the second gear 630, thereby driving the second gear 630 to rotate. Simultaneously, the second gear 630 and the first gear 512 are coaxial gears, causing the first gear 512 to rotate as well, thereby driving the flexible rack 511 to move.

[0088] Understandably, there are two flexible racks 511, and correspondingly, there are also two first gears 512. There are also two second gears 630, and the first gears 512 and second gears 630 are coaxially arranged, meaning there are two coaxial gears formed by the first gears 512 and second gears 630. More specifically, along the length of the worm gear 620, the worm gear 620 has a second tooth section 622, a first tooth section 621, and another second tooth section 622 in sequence. The first tooth section 621 meshes with the drive motor 610, and the two second tooth sections 622 mesh with the two second gears 630 respectively, thereby sequentially driving the first gear 512 to rotate and the flexible rack 511 to move. Thus, by setting up a single power component, the two first gears 512 can be driven, which simplifies the structure of the power component 600 and the pusher 510, and contributes to the lightweight design of the smart glasses. In one embodiment, in order to ensure the normal rotation of the coaxial first gear 512 and second gear 630 and to avoid the influence of other structural components on the rotation of the first gear 512 and second gear 630, a gear cover plate 513 is provided on the first gear 512 and second gear 630, and the gear cover plate 513 is connected to the frame body 100.

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

[0090] Please see Figure 4 , Figures 12 to 16 In an embodiment of the present invention, the smart glasses also include a nose pad cover 300 disposed in the frame body 100. The nose pad cover 300 is provided with a positioning groove 310 corresponding to the nose pad opening 110. The ejector 520 includes a top block 521 movably disposed in the positioning groove 310, a permanent magnet 524 disposed on the bottom of the top block 521 facing 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 300 is disposed within the frame body 100, that is, the nose pad cover 300 is located within the receiving space, and the nose pad cover 300 covers the opening of the mounting groove 120, thereby placing the nose pad body 400 between one side wall of the frame body 100 and the nose pad cover 300. In one embodiment, the frame body 100 has a connecting hole near the mounting groove 120, and the nose pad cover 300 also has a corresponding connecting hole. Screws or other connectors pass through the two connecting holes, thereby detachably connecting the nose pad cover 300 and the frame body 100. This avoids collisions with the nose pad body 400 and improves the protection of the nose pad body 400. Of course, in other embodiments, the nose pad cover 300 and the frame body 100 can also be snap-fitted together; the connection method between the two is not limited here.

[0092] Please see Figure 4 and Figure 15 In one embodiment, the smart glasses further include a flexible circuit board 700, which includes a main circuit board 710, an intermediate circuit board 720, and a nose pad circuit board 730. 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, the main circuit board 710 is provided with a first connector 711, and the intermediate circuit board 720 is electrically connected to the main circuit board 710 through the first connector 711. The intermediate circuit board 720 is provided with a second connector 721, and the nose pad circuit board 730 is electrically connected to the intermediate circuit board 720 through the second connector 721. In the solution shown in the figures of this invention, the controller 910 mentioned above is located on the main circuit board 710, and the drive motor 610 is located on the intermediate circuit board 720. To facilitate the transmission connection between the drive motor 610 and the worm gear 620, the intermediate circuit board 720 is provided with a first branch 722 for mounting the drive motor 610, thereby providing power to the drive motor 610.

[0093] In one embodiment, the nose pad circuit board 730 is also provided with other electronic components, such as a pressure sensor and a bone conduction sensor. Taking the pressure sensor as an example, in one embodiment, the pressure sensor is electrically connected to the controller 910. The pressure sensor is used to detect the pressure value when the nose pad body 400 contacts the bridge of the nose. When the pressure value reaches a first preset pressure, the nose pad body 400 reaches a first preset height. Here, the first preset pressure is not limited.

[0094] In the embodiments shown in the figures of this invention, please refer to... Figure 5 , Figure 17 and Figure 18The nose pad circuit board 730 has a roughly U-shaped structure, specifically including a first segment 731, a bent segment 732, and a second segment 733 connected in sequence, with the first segment 731 and the second segment 733 arranged roughly in parallel. The first segment 731 of the nose pad circuit board 730 is located inside the nose pad body 400, the bent segment 732 and part of the second segment 733 are located inside the mounting groove 120, and the other part of the second segment 733 is located outside the nose pad cover plate 300. That is, after the first segment 731 of the nose pad circuit board 730 passes through a series of bendable parts 410 and non-bendable parts 420, it extends out from one end of the nose pad body 400 and is bent to form the bent segment 732. The second segment 733 extends within the mounting groove 120 and then passes through the nose pad cover plate 300. In one embodiment, in order for the second segment 733 to extend out of the nose pad cover 300, a stepped portion 734 is formed on the second segment 733, and a through hole is provided on the nose pad cover 300. The stepped portion 734 extends into the through hole and allows the free end of the second segment 733 to protrude and be located above the nose pad cover 300.

[0095] Please see Figure 12 , Figure 14 and Figure 16 The nose pad cover 300 has a positioning groove 310 on the side facing the frame body 100. When the nose pad cover 300 is placed on the mounting groove 120, the positioning groove 310 corresponds to 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 disposed within the positioning groove 310, meaning that the top block 521 can move relative to the positioning groove 310 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 opening end of the positioning groove 310 to abut the nose pad body 400. In one embodiment, to facilitate ejecting the nose pad body 400 from the nose pad opening 110, one end of the top block 521 has a 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 has a permanent magnet 524.

[0096] Please see Figure 15 and Figure 16 In one embodiment, an electromagnet 525 is disposed on an intermediate circuit board 720 for electrical connection with a controller 910, and the electromagnet 525 corresponds to a permanent magnet 524. More specifically, to facilitate the cooperation between the electromagnet 525 and the permanent magnet 524, the intermediate circuit board 720 is provided with a second branch 723, which is located above the side of the nose pad cover 300 away from the mounting groove, and the electromagnet 525 is disposed on the second branch 723. In one embodiment, to facilitate the positioning and installation of the second branch 723, an electromagnetic groove 320 is provided on the side of the nose pad cover 300 away from the frame body 100 (e.g., Figure 11As shown, the electromagnetic slot 320 is used to accommodate the second branch 723, and the electromagnet 525 is located 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 cover plate 300.

[0097] Understandably, in one embodiment, the controller 910 is electrically connected to the electromagnet 525. When the nose pad body 400 needs to be pushed out, the controller 910 controls the electromagnet 525 to be energized. The electromagnet 525 and the permanent magnet 524 have the same polarity and repel each other. Under the action of the repulsive force, the permanent magnet 524 moves away from the electromagnet 525, thereby driving the top block 521 to move towards 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, causing it to arch towards the nose pad opening 110. Under the push of the pusher 510, the nose pad body 400 tends to bulge outward towards the nose pad opening 110, and the bendable part 410 bends, causing the nose pad body 400 to bulge out of the nose pad opening 110. When the nose pad body 400 bulges outward toward the nose pad opening 110 and detaches from the contact with the top block 521, the controller 910 controls the electromagnet 525 to be de-energized and lose polarity, thereby eliminating the repulsive force between the electromagnet 525 and the permanent magnet 524, thus removing the supporting force for the top block 521 to move toward the nose pad opening 110.

[0098] Of course, in other embodiments, the ejector 520 may also include a top block, a rotating shaft motor, a winding shaft, an adjusting rope, and an elastic element. The lower end of the top block is provided with an elastic element, and the elastic element is provided with an adjusting rope. One end of the adjusting rope is fixed to the elastic element, and the other end is wound around the winding shaft. The winding shaft is connected to the rotating shaft motor for transmission, so that it rotates with the rotating shaft motor. When the ejector 520 does not need to eject the nose pad body 400, the adjusting rope is wound around the winding shaft, causing the adjusting rope to compress the elastic element. When the ejector 520 needs to eject the nose pad body 400, the rotating shaft motor operates, driving the winding shaft to rotate. The adjusting rope is released from the winding shaft, and as the adjusting rope is released, the elastic element is released and extends, causing the elastic element to drive the top block to eject the nose pad body 400.

[0099] Please see Figure 12 and Figure 13 In an embodiment of the present invention, the side wall of the positioning groove 310 is provided with a limiting hole 311, and the top block 521 is provided with a limiting pin 522. The limiting pin 522 extends into the limiting hole 311 and 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 embodiment shown in the figures of this invention, the top block 521 is provided with a limiting pin 522. In one embodiment, the side wall of the top block 521 is provided with a mounting hole 523, which corresponds to the limiting hole 311. The top block 521 is installed into the positioning groove 310, and then the limiting pin 522 is passed through the limiting hole 311 and the mounting hole 523 in sequence. The limiting pin 522 matches the mounting hole 523 exactly, that is, the limiting pin 522 will not move within the mounting hole 523. Part of the limiting pin 522 is exposed outside the mounting hole 523, and the portion of the limiting pin 522 exposed outside the mounting hole 523 is located inside the limiting hole 311. In one embodiment, the outer surface of the limiting pin 522 is flush with the outer surface of the side wall of the positioning groove 310. It can be understood that the diameter of the limiting hole 311 is greater than the outer diameter of the limiting pin 522, thereby allowing the limiting pin 522 to move within the limiting hole 311. The diameter length of the limiting hole 311 determines the maximum range of the ejection stroke of the top block 521. The diameter length of the limiting hole 311 can be set according to requirements and is not limited here. It is worth noting that the diameter 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] Understandably, when the electromagnet 525 is not energized, the top block 521 is in contact with the bottom wall of the positioning groove 310, with the end of the top block 521 facing away from the bottom wall of the positioning groove 310 located inside the nose pad opening 110. When the controller 910 controls the electromagnet 525 to be energized, a repulsive force is generated between the electromagnet 525 and the permanent magnet 524. Under the action of this repulsive force, the top block 521 moves away from the bottom wall of the positioning groove 310, that is, the top block 521 moves towards 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 facing 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 detaches from the contact with the top block 521, the controller 910 controls the electromagnet 525 to be de-energized and lose polarity, thus preventing it from pushing the permanent magnet 524 on the top block 521. The top block 521 then stops moving outward from the nose pad opening 110. When the nose pad module 200 switches from the used state to the hidden state, the nose pad body 400, located outside the nose pad opening 110, moves inward from the nose pad opening 110 under the action of the pusher 510. When the nose pad body 400 moves to contact the top block 521, the top block 521 is not subjected to repulsive force. Under the action of the nose pad body 400, the top block 521 also moves inward from the nose pad opening 110 until the nose pad body 400 lies flat on the frame body 100.

[0102] Please see Figure 3 , Figure 6 , Figure 17 and Figure 18In an embodiment of the present invention, the nose pad body 400 is further provided with an expansion film 430, which can protrude at least from the side of the nose pad body 400 near 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 film 430.

[0103] Specifically, the nose pad body 400 is flexible and also has an expansion film 430. The expansion film 430 can expand and protrude towards the bridge of the nose, so that the distance between the left and right nose pads 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 can be adjusted, so that the smart glasses can be adapted to nose bridges of different widths, thus improving the applicability of the smart glasses.

[0104] The adjustment assembly 500 also includes an inflation assembly 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 assembly 800 to work. Under the inflation of the inflation assembly 800, the expansion film 430 begins to expand and protrude towards the side closer 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 protrude in other directions while being able to expand and protrude towards the side closer to the bridge of the nose; this is not a limitation. It is understood that the expansion membrane 430 is primarily designed to adjust the distance between the nose pad body 400 and the bridge of the nose. The following explanation will use the example where the expansion membrane 430 can only expand and protrude towards the side closer to the bridge of the nose.

[0106] In one embodiment, an expansion membrane 430 is disposed on the inflexible portion 420. An air-containing cavity 422 is formed within the inflexible portion 420, and at least a portion of the inflation assembly 800 is located within the air-containing cavity. The expansion membrane 430 is configured as the cavity wall of the air-containing cavity 422 facing the bridge of the nose. It is understood that other areas of the inflexible portion 420 cannot deform; only the expansion membrane 430 can expand or retract under the influence of the inflation assembly 800. This allows the expansion membrane 430 to expand precisely only towards the bridge of the nose, thus preventing it from expanding in other directions while expanding towards the bridge of the nose, thereby avoiding additional energy consumption by the inflation assembly 800 and improving its efficiency.

[0107] Understandably, the nose pad body 400 includes multiple non-bendable portions 420 and bendable portions 410. When wearing smart glasses, only a portion of the non-bendable portions 420 and bendable portions 410 of the nose pad body 400 contact the bridge of the nose. In one embodiment, an expansion film 430 is provided only on six non-bendable portions 420 in the middle portion of the nose pad body 400. This avoids additional energy consumption of the inflation assembly 800. Of course, the number of expansion films 430 can be set according to actual needs and is not limited here.

[0108] An expansion membrane 430 is disposed in the non-bendable portion 420. When the expansion membrane 430 expands, the expansion membranes 430 on the adjacent non-bendable portions 420 expand simultaneously, while no expansion area 421 is provided in the bendable portion 410. The location of the bendable portion 410 provides expansion space for the expansion membrane 430. However, it is understandable that the bendable portion 410 is made of a deformable material. If an expansion membrane 430 is disposed in the bendable portion 410, when the inflation assembly 800 operates, the areas on the bendable portion 410 without the expansion membrane 430 will also expand and deform, which is detrimental to controlling the expansion direction.

[0109] Understandably, the adjustment component 500 can adjust the distance between the nose pad module 200 and the bridge of the nose along the front-to-back direction of the line of sight, and the inflation component 800 can adjust the distance between the nose pad module 200 and the bridge of the nose along the left-to-right direction of the bridge of the nose. Thus, in one embodiment, the height of the smart glasses can be adjusted by the cooperation of the adjustment component 500 and the inflation component 800. Of course, in other embodiments, the height of the smart glasses can also be adjusted by either the adjustment component 500 or the inflation component 800 alone.

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

[0111] Specifically, in one embodiment, the nose pad module 200 does not include a bendable nose pad body 400, but instead uses an expansion film 430 to switch between a hidden state and a used state. Meanwhile, the adjustment component 500 includes an inflation component 800, which controls the expansion and contraction of the expansion film 430. More specifically, when the nose pad module 200 is in the hidden state, the controller 910 controls the inflation component 800 not to inflate the expansion film 430; the expansion film 430 is in a contracted state and does not protrude from the plane of the nose pad opening 110. When the nose pad module 200 is in the used state, the controller 910 controls the inflation component 800 to inflate the expansion film 430. The expansion film 430 begins to expand and is squeezed out from the frame body 100 through the nose pad opening 110, causing the expansion film 430 to protrude outward from the nose pad opening 110 to contact the bridge of the nose. When the nose pad module 200 switches from the active state to the hidden state, the controller 910 controls the inflation component 800 to deflate the expansion membrane 430, causing the expansion membrane 430 to contract and retract into the nose pad opening 110. Thus, by simply providing the expansion membrane 430 in the nose pad module 200, the switching between the hidden and active states can be achieved through adjustment of the inflation component 800. It is noteworthy that in this embodiment, the expansion membrane 430 at least protrudes beyond the nose pad opening 110; that is, in this embodiment, the expansion membrane 430 at least has a convex deformation in the front-to-back direction of the line of sight.

[0112] Please see Figure 4 and Figure 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 and the inflation / deflation motor 810.

[0113] Specifically, the following description uses a nose pad module 200 excluding the bendable nose pad body 400, but including the expansion film 430 as an example. When the controller 910 controls the inflation / deflation motor 810 to inflate the expansion film 430 through the air duct 820, the expansion film 430 protrudes from the nose pad opening 110, thus putting the nose pad module 200 into use. When the controller 910 controls the inflation / deflation motor 810 to deflate the expansion film 430 through the air duct 820, the expansion film 430 contracts and retracts into the nose pad opening 110, thus putting the nose pad module 200 into a hidden state.

[0114] The following description uses a nose pad body 400, including a bendable portion 410, a non-bendable portion 420, and an expansion film 430, as an example. Specifically, in the embodiment shown in the figures of this invention, the inflation / deflation motor 810 is located on the second branch 723 of the intermediate circuit board 720 to provide power to the inflation / deflation motor 810. The air duct 820 is generally U-shaped. In one embodiment, the air duct 820 is arranged side by side with the nose pad circuit board 730. After passing through each bendable portion 410 and non-bendable portion 420, the air duct 820 is bent and extends within the mounting groove 120 before passing through the nose pad cover plate 300. The end of the air duct 820 inside the nose pad body 400 is a closed end, and the end of the air duct 820 extending out of the nose pad cover plate 300 is an open end, which is connected to the inflation / deflation motor 810. Understandably, the air tube 820 is made of a flexible material so that it can protrude outward with the nose pad body 400.

[0115] In one embodiment, both the non-bendable portion 420 and the bendable portion 410 are configured as hollow structures, which facilitates the weight reduction of the nose pad body 400. In another embodiment, adjacent hollow structures are independent of each other. The nose pad circuit board 730 and the air guide tube 820 pass through the hollow structures of the non-bendable portion 420 and the bendable portion 410. Specifically, the non-bendable portion 420 forms an air-containing cavity 422, and the air guide tube 820 has an air guide hole 821 in the air-containing cavity 422, that is, the gas in the air guide tube 820 can enter the air-containing cavity 422 through the air guide hole 821. In other words, each air-containing cavity 422 can only be connected through the air guide hole 821 on the air guide tube 820.

[0116] Understandably, in one embodiment, the inflation / deflation motor 810 is electrically connected to the controller 910. When it is necessary to reduce the distance between the nose pad module 200 and the bridge of the nose, the controller 910 controls the inflation / deflation motor 810 to inflate. The gas enters the corresponding air chamber 422 through the air guide hole 821 on the air guide tube 820. As inflation proceeds, the expansion area 421 begins to expand, thereby bringing the nose pad body 400 closer to the bridge of the nose. When it is necessary to increase the distance between the nose pad module 200 and the bridge of the nose, the controller 910 controls the inflation / deflation motor 810 to deflate. The gas in the air chamber 422 is drawn into the air guide tube 820 through the air guide hole 821 and discharged from the air chamber 422, thereby causing the expansion area 421 to shrink back, thus moving the nose pad module 200 away from the bridge of the nose.

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

[0118] Understandably, the expansion membrane 430 is elastic, capable of elastic deformation under external force and recovering its shape after the force is removed. This allows the expansion membrane 430 to expand or contract when the inflation / deflation motor 810 inflates or deflates. In one embodiment, the expansion membrane 430 is made from a thermoplastic resin such as polyethylene or polypropylene using a special process. Understandably, when wearing smart glasses, the expansion membrane 430 comes into contact with the bridge of the nose, and its softness improves 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 includes only a bendable nose pad body 400, the controller 910, upon receiving a nose pad adjustment signal, controls the adjustment component 500 to bend the nose pad body 400 according to the nose pad adjustment signal, and bends it until it protrudes a first preset height 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 film 430 disposed on the nose pad body 400, the controller 910, upon receiving a nose pad adjustment signal, controls the adjustment component 500 to first bend the nose pad body 400 until it protrudes a first preset height relative to the nose pad opening 110, and then controls the inflation component 800 to inflate the expansion film 430 so that the expansion film 430 expands to protrude a second preset height relative to the side of the nose pad body 400 near the bridge of the nose; or,

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

[0122] Understandably, 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 based on the received nose pad adjustment signal. The nose pad adjustment signal can be emitted by an electrical device installed within the frame body 100 and electrically connected to the controller 910, such as a distance sensor 920, a pressure sensor, etc., and is 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 ranges of the first and second preset heights can be set according to needs and are not limited here.

[0123] Thus, the height of the smart glasses can be controlled individually by the height of the nose pad body 400 protruding outward (i.e., the first preset height); or, it can be controlled jointly by the height of the nose pad body 400 protruding outward (i.e., the first preset height) and the height of the expansion film 430 protruding (i.e., the second preset height); or, it can also be controlled individually by the height of the expansion film 430 bulging outward (i.e., the first preset height).

[0124] In an embodiment of the present invention, the frame body 100 is further provided with a distance sensor 920 electrically connected to the controller 910. 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, which includes a bendable nose pad body 400, as an example, please refer to... Figure 4 The frame body 100 is equipped with a distance sensor 920 electrically connected to the controller 910. When the smart glasses are worn, the distance sensor 920 detects the distance between the frame body 100 and the bridge of the nose. When the detected distance signal value is less than a predetermined distance range, the controller 910 controls the adjustment component 500 to operate, thereby causing the nose pad body 400 to protrude outward until it reaches a first preset height. In this embodiment, the distance sensor 920 detects whether the smart glasses are properly worn. Once the distance sensor 920 detects that the smart glasses are properly worn, the controller 910 then controls the adjustment component 500 to make the nose pad body 400 protrude outward. It is worth noting that the predetermined distance range can be set according to actual conditions and is not limited here. Thus, by setting the controller 910 and the distance sensor 920, the automation of using the smart glasses is improved.

[0126] In one embodiment, the distance sensor 920 can be configured as an infrared distance sensor or a proximity sensor; the type of distance sensor 920 is not limited here. In one embodiment, the distance sensor 920 is disposed on the bridge of the nose of the frame body 100, specifically on the side of the bridge of the nose facing downwards from the line of sight, which is beneficial to the reliability of the detected distance signal value. Of course, the distance sensor 920 can also be disposed in other positions on the frame body 100; there are no limitations on this.

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

[0128] Specifically, please refer to Figure 10The frame body 100 of the smart glasses is also equipped with an adjustment button 930. When it is necessary to switch between the hidden and active states of the nose pad module 200, pressing the adjustment button 930 controls the operation of the adjustment component 500. Thus, the state of the nose pad module 200 can be adjusted before or after wearing the smart glasses, thereby improving the versatility of the smart glasses. In one embodiment, for convenient pressing of the adjustment button 930, the adjustment button 930 is located on the temple of the frame body 100, specifically at the end of the temple near the lens rim. Of course, the adjustment button 930 can also be located in other positions on the frame body 100, and there are no limitations on this.

[0129] In other embodiments, the smart glasses are equipped with both a distance sensor 920 and an adjustment button 930. Before wearing the smart glasses, the adjustment button 930 is pressed, causing the nose pad body 400 to protrude to a third preset height. 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 protrusion height of the nose pad body 400 to the first preset height, thereby ensuring that the smart glasses are always at the same height above the bridge of the nose.

[0130] It is worth noting that in this embodiment, the distance sensor 920 detects the distance between the nose pad body 400, which protrudes from the nose pad opening 110, and the bridge of the nose. Generally, the third preset height is similar to the first preset height, and no limitation is placed on the difference between the third preset height and the first preset height.

[0131] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
