Description

Technical Field

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

[0002] Eyeglasses generally consist of a frame, lenses, and temples. For comfortable wear, nose pads are usually added where the frame contacts the bridge of the nose.

[0003] The nose pads of existing glasses are fixedly connected to the frames. Considering the differences in the shape of different users' noses, fixed nose pads may cause uneven pressure distribution, which may lead to discomfort when worn for a long time. Summary of the Invention

[0004] The main objective of this invention is to provide a smart glasses solution that aims to improve the wearing comfort of smart glasses.

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

[0006] The frame itself is equipped with a controller; and

[0007] A nose pad module includes a nose pad leg and a nose pad assembly connected together. The nose pad assembly is used to contact the nose. The nose pad leg is mounted on the frame body and has a bendable state and a non-bendable state. A controller is electrically connected to the nose pad leg and is used to control the nose pad leg to switch to the bendable state. When the nose pad leg is in the bendable state, the position of the nose pad assembly can be adjusted by bending the nose pad leg.

[0008] In one embodiment, the nose support leg comprises a heat-deformable material, and when the temperature of the nose support leg is higher than a first preset temperature, the nose support leg is in the bendable state.

[0009] In one embodiment, when the temperature of the nose pad is higher than a second preset temperature but lower than a third preset temperature, the nose pad is in an ideal bendable state; the second preset temperature is higher than the first preset temperature; the smart glasses also include a reminder device electrically connected to the controller, and in the ideal bendable state, the controller controls the reminder device to send an adjustment reminder to the user.

[0010] In one embodiment, the heat-deformable material comprises a thermotropic shape memory polymer.

[0011] In one embodiment, the nose support leg includes a heating element located within the heat-deformable material and electrically connected to the controller; the controller controls the operation of the heating element to control the nose support leg to be in the bendable state or the non-bendable state.

[0012] In one embodiment, the nose pad leg further includes a nose pad flexible element and a nose pad wiring harness wrapped within the nose pad flexible element. The nose pad flexible element is sleeved on the outside of the heat-deformable material, and the nose pad wiring harness is used to electrically connect the controller to electrical components on the nose pad assembly.

[0013] In one embodiment, the nose pad assembly is provided with an eye sensor electrically connected to the controller. The eye sensor is used to identify the position information of the eyeball. The controller compares the eye position information detected by the eye sensor with a first preset eye position. When the eye position information is inconsistent with the first preset eye position, the controller controls the nose pad leg to be in the bendable state so as to adjust the position of the eye sensor by bending the nose pad leg.

[0014] In one embodiment, the nose pad assembly includes a mounting base and a nose pad body, the mounting base being connected to the nose pad leg, and the nose pad body and the eye sensor being respectively mounted on opposite sides of the mounting base.

[0015] In one embodiment, the leaf assembly further includes a leaf cover plate, the mounting base is provided with a first mounting port, at least a portion of the leaf body extends into the first mounting port, and the leaf cover plate is located within the mounting base and connected to the leaf body.

[0016] In one embodiment, the mounting base has a mounting groove at one end facing the leaf body, and the bottom of the mounting groove has a first mounting opening; the leaf body includes a contact portion and a connecting portion connected to each other, the connecting portion is located in the mounting groove and can swing relative to the mounting groove, and at least a portion of the leaf body extends into the first mounting opening, and a swing gap is provided between the leaf cover plate and the groove wall of the mounting groove.

[0017] In one embodiment, the swing angle of the connecting portion relative to the mounting groove is in the range of 0-10°.

[0018] In one embodiment, the nose pad module further includes a locking structure for locking the sway of the nose pad body relative to the mounting base.

[0019] In one embodiment, the locking structure includes an electromagnet disposed in one of the mounting groove and the connecting portion, and a magnetic element disposed in the other. The controller is electrically connected to the electromagnet to control the energization or de-energization of the electromagnet, thereby controlling the attraction or de-attraction between the electromagnet and the magnetic element to lock or unlock the swing of the leaf body.

[0020] In one embodiment, a bone conduction sensor is provided within the contact portion; and / or, a microphone is provided within the contact portion.

[0021] The technical solution of this invention involves incorporating a frame body and a nose pad module into smart glasses. The frame body includes a controller, and the nose pad module comprises a connected nose pad leg and a nose pad assembly. The nose pad assembly contacts the nose. The nose pad leg is mounted on the frame body and has a bendable and a non-bendable state. The controller is electrically connected to the nose pad leg and controls it to switch to the bendable state. When the nose pad leg is in the bendable state, the position of the nose pad assembly can be adjusted by bending it. Thus, compared to the fixed nose pad relative to the frame body in the prior art, the nose pad leg in this invention has both bendable and non-bendable states. This allows the nose pad assembly to adapt to different nose bridge shapes, improving the wearing comfort of the smart glasses. Furthermore, it ensures that the nose pad assembly remains in its adjusted position, preventing unintentional adjustment and guaranteeing the wearing stability of the smart glasses.

[0040] Eyeglasses generally consist of a frame, lenses, and temples. For comfortable wear, nose pads are usually added where the frame contacts the bridge of the nose.

[0041] The nose pads of existing glasses are fixedly connected to the frames. Considering the differences in the shape of different users' noses, fixed nose pads may cause uneven pressure distribution, which may lead to discomfort when worn for a long time.

[0042] This invention proposes a smart glasses.

[0043] Please see Figures 1 to 3 In one embodiment of the present invention, the smart glasses include a frame body 100 and a nose pad module 200. The frame body 100 is provided with a controller 110. The nose pad module 200 includes a nose pad temple 300 and a nose pad assembly 400 connected to each other. The nose pad assembly 400 is used to contact the nose. The nose pad temple 300 is installed on the frame body 100 and has a bendable state and a non-bendable state. The controller 110 is electrically connected to the nose pad temple 300 and is used to control the nose pad temple 300 to switch to the bendable state. When the nose pad temple 300 is in the bendable state, the position of the nose pad assembly 400 can be adjusted by bending the nose pad temple 300.

[0044] Specifically, one end of the nose pad leg 300 is mounted on the frame body 100, and the other end is connected to the nose pad assembly 400 to provide mounting support for the nose pad assembly 400. 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. The left and right nose pads have identical structures, are positioned opposite each other, and are electrically connected to the controller 110, enabling the controller 110 to control both the left and right nose pads to switch to a bendable state.

[0045] When the controller 110 switches the nose pad 300 to the bendable state, the user can manually bend the nose pad 300 to adjust the position of the nose pad assembly 400 until the nose pad assembly 400 is in the correct position. Once the nose pad assembly 400 is in the correct position, the nose pad 300 remains in the adjusted posture; that is, it is in a non-bendable state. This ensures the nose pad assembly 400 remains in the adjusted position, preventing positional changes due to external forces or other conditions. Understandably, bending the nose pad 300 can be done not only by directly bending it by hand but also by pressing on the frame body 100. In this way, by setting the nose pad 300 to have a bendable state and a non-bendable state, on the one hand, the nose pad assembly 400 can be adapted to different shapes of nose bridges, thereby improving the wearing comfort of smart glasses; on the other hand, it can keep the nose pad assembly 400 in the adjusted position, avoiding the non-active adjustment of the nose pad assembly 400 and ensuring the wearing stability of smart glasses.

[0046] Understandably, adjusting the position of the nose pad assembly 400 could be to improve the wearing comfort of the smart glasses. Of course, when storing the smart glasses, if the posture of the nose pad 300 does not match the shape of the space containing it, the nose pad 300 can be switched to a bendable state to facilitate storage. That is, the nose pad 300 can be in a bendable state whether the smart glasses are being worn or stored.

[0047] In one embodiment, the smart glasses are equipped with a contact sensor located on the frame body 100 or the nose pad assembly 400. When the contact sensor detects a contact signal, it transmits the signal to the controller 110. The controller 110 receives the contact signal and controls the nose pad 300 to switch to a bendable state. In another embodiment, the smart glasses are equipped with an adjustment button. When the position of the nose pad assembly 400 needs to be adjusted, pressing the adjustment button will cause the controller 110 to control the nose pad 300 to switch to a bendable state. Here, no restrictions are placed on the triggering conditions for the controller 110 to control the nose pad 300 to switch to a bendable state.

[0048] It is worth noting that the control logic of the controller 110 and the nose support leg 300 in this invention, as well as the control logic of the controller 110 and other components mentioned below, are all prior art and will not be described in detail here.

[0049] In an embodiment of the present invention, the nose support leg 300 includes a heat-deformable material 310. When the temperature of the nose support leg 300 is higher than a first preset temperature, the nose support leg 300 is in a bendable state. Specifically, when the temperature of the nose support leg 300 is higher than the first preset temperature, the heat-deformable material 310 changes, and at this time the heat-deformable material 310 has deformation capability, thereby making the nose support leg 300 bendable.

[0050] In one embodiment, when the temperature of the nose support leg 300 is higher than a second preset temperature but lower than a third preset temperature, the nose support leg 300 is in an ideal bendable state; the second preset temperature is higher than the first preset temperature; the smart glasses also include a reminder device electrically connected to the controller 110, and in the ideal bendable state, the controller 110 controls the reminder device to send an adjustment reminder to the user.

[0051] Specifically, in one embodiment, the nose support leg 300 has an ideal bendable state. This ideal bendable state refers to a state where the nose support leg 300 exhibits optimal bending performance. As the temperature increases, the deformation capability of the heat-deformable material 310 gradually strengthens. When the temperature rises from a first preset temperature to a second preset temperature, the heat-deformable material 310 begins to exhibit optimal bending performance. It is understood that when the temperature is too high, the heat-deformable material 310 may experience shape memory effect and hyperelastic failure, and may even suffer irreversible structural damage. Therefore, the heat-deformable material 310 needs to have a limited temperature limit. In one embodiment, the bending performance of the heat-deformable material 310 is optimal when the nose support leg 300 is between the second and third preset temperatures.

[0052] In one embodiment, the smart glasses also include a reminder device electrically connected to the controller 110. Specifically, the reminder device can be a sound-emitting device, such as a speaker. The smart glasses also include a temperature sensor electrically connected to the controller 110. The temperature sensor detects the temperature of the nose pad 300 and transmits the temperature signal to the controller 110. The controller 110 receives the temperature signal and compares it with a second preset temperature and a third preset temperature. When the temperature signal is between the second and third preset temperatures, the controller 110 controls the sound-emitting device to emit a prompt sound to remind the user that the nose pad 300 is in an ideal bendable state, thus facilitating user adjustment. Of course, in other embodiments, the reminder device can also be a light-emitting device, etc.

[0053] In one embodiment, when the temperature signal received by the controller 110 from the temperature sensor is greater than or equal to a third preset temperature, the controller 110 controls the cancellation of heating of the nose support leg 300 to prevent damage to the heat-deformable material 310.

[0054] Understandably, there are many types of heat-deformable materials 310, and different materials have different deformation temperatures. Therefore, the first preset temperature is not limited here. The ideal deformation temperature range varies for different materials, so the second and third preset temperatures are not limited here.

[0055] In embodiments of the present invention, the heat-deformable material 310 includes a thermotropic shape memory polymer. Specifically, a thermotropic shape memory polymer refers to a polymeric material that triggers a shape memory effect through temperature changes, such as thermoplastic polyurethane (TPU), polycaprolactone-type polyurethane (PCL-PU), polylactic acid (PLA), polycaprolactone (PCL), etc. The specific material of the heat-deformable material 310 is not limited herein.

[0056] Understandably, the heat-deformable material 310 can be bent and deformed by heating, and its shape can be fixed by cooling. That is, when the heat-deformable material 310 is in a heated state, the nose support leg 300 is in a bendable state; when the heat-deformable material 310 is in a cooled state, the nose support leg 300 is in a non-bendable state. Understandably, the controller 110 is electrically connected to the nose support leg 300. When the position of the leaf assembly 400 needs to be adjusted, the controller 110 controls the heating of the nose support leg 300, so that the heat-deformable material 310 is in a heated state. When the temperature of the heat-deformable material 310 reaches a first preset temperature, the nose support leg 300 switches to a bendable state. At this time, the position of the nose support leg 300 is adjusted by bending the nose support leg 300. After the position of the nose support leg 400 is adjusted to the correct position, the controller 110 controls the removal of heating on the nose support leg 300, thereby causing the temperature of the heat-deformable material 310 to drop and the heat-deformable material 310 to be in a cooling state. When the temperature of the heat-deformable material 310 drops below the first preset temperature, the heat-deformable material 310 can no longer be deformed and bent. At this time, the nose support leg 300 is in an unbendable state.

[0057] Understandably, in smart glasses, the heat-deformable material 310 is small in size and can be cooled naturally without the need for additional heat dissipation devices.

[0058] Of course, in other embodiments, the nose bridge leg 300 may also include an electrodeformable material, such as a bistable electroactive polymer (BSEP). A control circuit board 120 is also mounted on the frame body 100, and a controller 110 is disposed on the control circuit board 120. The control circuit board 120 can apply an electric field to the bistable electroactive polymer, thereby softening the polymer and allowing it to deform. When the control circuit board 120 removes the electric field from the bistable electroactive polymer, the polymer returns to its rigidity and cannot deform. In one embodiment, to improve the safety of the deformable component, an insulating layer is also included on the outside of the bistable electroactive polymer.

[0059] Please see Figure 4 In an embodiment of the present invention, the nose support leg 300 includes a heating element 320, which is located within the heat-deformable material 310 and is electrically connected to the controller 110. The controller 110 controls the operation of the heating element 320 to control the nose support leg 300 to be in a bendable or non-bendable state.

[0060] Specifically, in one embodiment, the nose support leg 300 includes a heating element 320 electrically connected to the controller 110, the heating element 320 being enclosed within a heat-deformable material 310. It is understood that at room temperature, the heat-deformable material 310 is a rigid component and cannot deform; when heated, the rigidity of the heat-deformable material 310 changes, allowing it to deform.

[0061] The controller 110 is electrically connected to the heating element 320 to control the operation of the heating element 320. In one embodiment, the controller 110 is disposed on the control circuit board 120, which is electrically connected to the heating element 320 via a wiring harness to supply power to the heating element 320.

[0062] When the contact sensor or adjustment button on the smart glasses is triggered, the controller 110 receives the trigger signal and controls the heating element 320 to operate, heating the heat-deformable material 310 to switch the nose pad 300 to a bendable state, allowing it to be bent and thus moving the nose pad assembly 400 until it is adjusted into place. At this time, the controller 110 controls the heating element 320 to stop heating the heat-deformable material 310, allowing its temperature to decrease. As the temperature decreases, the heat-deformable material 310 can no longer deform, thus placing the nose pad 300 in a non-deformable state. In one embodiment, the heating element 320 can be a heating wire, a flexible silicone heating sheet, etc., and is not limited thereto. It is understood that the heating element 320 also needs to be flexible so that it can bend along with the heat-deformable material 310.

[0063] Please see Figure 4 In an embodiment of the present invention, the nose pad leg 300 further includes a nose pad flexible member 340 and a nose pad wiring harness 330 wrapped within the nose pad flexible member 340. The nose pad flexible member 340 is sleeved on the outside of the heat-deformable material 310, and the nose pad wiring harness 330 is used to electrically connect the controller 110 and the electrical components on the nose pad assembly 400.

[0064] Specifically, to facilitate the installation of the nose pad wiring harness 330, the nose pad leg 300 also includes a nose pad flexible member 340. The nose pad flexible member 340 has multiple through holes for the nose pad wiring harness 330 to pass through, and the nose pad flexible member 340 is sleeved on the outside of the heat-deformable material 310. It is understood that the nose pad wiring harness 330 is a flexible member; when the nose pad leg 300 is in a bendable state, the nose pad flexible member 340 and the nose pad wiring harness 330 can bend together with the heat-deformable material 310 under the action of external force. In one embodiment, the nose pad flexible member 340 is configured as a silicone member or a rubber member, etc.

[0065] Understandably, the nose pad assembly 400 is equipped with electrical components, such as the eye sensor 500, electromagnet 414, bone conduction sensor 424, and microphone 425 mentioned below. These electrical components need to be electrically connected to the controller 110. In one embodiment, the control circuit board 120 on which the controller 110 is mounted is equipped with a connecting harness 130, and the nose pad leg 300 is equipped with a nose pad harness 330. One end of the nose pad harness 330 is electrically connected to the connecting harness 130, and the other end of the nose pad harness 330 is connected to the eye sensor 500 and other electrical components, thereby realizing the electrical connection between the controller 110 and the electrical components on the nose pad assembly 400.

[0066] Please see Figures 1 to 3 In an embodiment of the present invention, the nose pad assembly 400 is provided with an eye sensor 500 electrically connected to the controller 110. The eye sensor 500 is used to identify the position information of the eyeball. The controller 110 compares the eyeball position information detected by the eye sensor 500 with a first preset eyeball position. When the eyeball position information is inconsistent with the first preset eyeball position, the controller 110 controls the nose pad leg 300 to be in a bendable state so as to adjust the position of the eye sensor 500 by bending the nose pad leg 300.

[0067] As is understandable, eye-tracking technology uses sensors to capture the movement characteristics of the eyeballs and uses algorithms to analyze this data to infer the user's gaze point. In smart wearable devices, eye tracking can enable touchless interaction, such as eye-controlled mice and keyboards. Currently, eye-tracking sensors are generally fixedly mounted on the frame of smart glasses. However, due to significant differences in facial features among different users (such as eye socket depth and nose bridge height), fixed eye-tracking sensor positions may not meet the needs of all users.

[0068] In this invention, an eye sensor 500 is mounted on the nose pad assembly 400. The eye sensor 500 can send the detected eye position information to a controller 110, which has a first preset eye position. When a user wears smart glasses, the eye sensor 500 can detect the user's eye position information. When the eye position information is inconsistent with the first preset eye position, the controller 110 controls the nose pad leg 300 to be in a bendable state. At this time, the user bends the nose pad leg 300 to adjust the position of the nose pad assembly 400, thereby adjusting the position of the eye sensor 500. When the eye position information sent by the eye sensor 500 is consistent with the first preset eye position, the eye sensor 500 is in the correct position, and the nose pad leg 300 is in a non-bendable state. In one embodiment, the eye sensor 500 can be a camera or an infrared eye tracker; the type of eye sensor 500 is not limited here.

[0069] Thus, the nose pad module 200 includes a nose pad leg 300 and a nose pad assembly 400 connected together. The nose pad leg 300 has a bendable state and a non-bendable state. In this invention, an eye sensor 500 is installed on the nose pad assembly 400, so that the relative position of the eye sensor 500 and the eyeball can be adjusted and fixed by changing the bendable and non-bendable states of the nose pad leg 300, thereby improving the effect of the eye sensor 500 in capturing eye movements and improving the usability of smart glasses.

[0070] Please see Figure 6 In an embodiment of the present invention, the nose pad assembly 400 includes a mounting base 410 and a nose pad body 420. The mounting base 410 is connected to the nose pad leg 300, and the nose pad body 420 and the eye sensor 500 are respectively mounted on opposite sides of the mounting base 410.

[0071] Specifically, the nose pad assembly 400 includes a mounting base 410 and a nose pad body 420 mounted on the mounting base 410, wherein the mounting base 410 is used to connect with the nose support leg 300, and the nose pad body 420 is used to contact the nose. In one embodiment, the nose pad body 420 and the eye sensor 500 are respectively mounted on opposite sides of the mounting base 410. This allows the eye sensor 500 to have a better position for capturing the eyeball, while also avoiding obstruction of the line of sight by the eye sensor 500.

[0072] Please refer to 5 to Figure 7 In an embodiment of the present invention, the leaf assembly 400 further includes a leaf cover plate 430, the mounting base 410 is provided with a first mounting port 411, at least a portion of the leaf body 420 extends into the first mounting port 411, and the leaf cover plate 430 is located in the mounting base 410 and connected to the leaf body 420.

[0073] Specifically, the mounting base 410 has a cavity and a first mounting port 411 communicating with the cavity. At least a portion of the leaf holder body 420 extends into the cavity through the first mounting port 411. A leaf holder cover plate 430 is disposed within the cavity of the mounting base 410 and covers the leaf holder body 420. In one embodiment, the leaf holder cover plate 430 is connected to the leaf holder body 420 by bolts or other connecting components. It should be noted that the size of the leaf holder cover plate 430 is larger than the size of the first mounting port 411 to prevent the leaf holder cover plate 430 from detaching from the cavity through the first mounting port 411. Thus, connecting the leaf holder cover plate 430 to the leaf holder body 420 prevents the leaf holder body 420 from detaching from the first mounting port 411, ensuring the stability of the connection between the leaf holder body 420 and the mounting base 410.

[0074] In one embodiment, the mounting base 410 is further provided with a second mounting port 412, through which the nose support leg 300 is mounted on the mounting base 410.

[0075] Please see Figure 6 and Figure 7 In an embodiment of the present invention, the mounting base 410 is provided with a mounting groove 413 at one end facing the leaf body 420, and the bottom of the mounting groove 413 is provided with a first mounting opening 411; the leaf body 420 includes a contact portion 421 and a connecting portion 422 connected to each other, the connecting portion 422 is located in the mounting groove 413 and can swing relative to the mounting groove 413, and at least a portion of the leaf body 420 extends into the first mounting opening 411, and a swing gap is provided between the leaf cover plate 430 and the groove wall of the mounting groove 413.

[0076] Understandably, when the nose support leg 300 is in a bendable state, the position of the eye sensor 500 can be adjusted by bending the nose support leg 300. Once the position of the eye sensor 500 is adjusted, the contact between the nose pad body 420 and the nose may be uncomfortable. To ensure that the nose pad body 420 provides a comfortable wearing experience for users when it contacts nose bridges of different shapes, this invention sets the nose pad body 420 into an angle-adjustable structure.

[0077] Specifically, the mounting base 410 has a mounting groove 413 formed at one end of the mounting leaf body 420, and the bottom of the mounting groove 413 has a first mounting opening 411. The mounting leaf body 420 includes a contact portion 421 and a connecting portion 422 connected to each other, wherein the contact portion 421 is used to contact the nose, and the connecting portion 422 is used to connect with the mounting base 410. In one embodiment, the mounting leaf body 420 is generally mushroom-shaped, the cross-section of the contact portion 421 is circular, and the connecting portion 422 is connected to the center of the contact portion 421. The end of the connecting portion 422 connected to the mounting base 410 is chamfered and is generally bullet-shaped, so that the structure of the connecting portion 422 matches the structure of the mounting groove 413, and the connecting portion 422 can swing relative to the mounting groove 413. At the same time, a swing gap is provided between the mounting leaf cover plate 430 and the inner wall of the mounting groove 413. Understandably, the nose pad cover 430 is connected to the nose pad body 420 via bolts or other connecting members. Specifically, the bolts or other connecting members connect the nose pad cover 430 and the nose pad body 420 together through the first mounting port 411, and the bolts or other connecting members are not connected to the mounting base 410. Thus, when the nose pad body 420 swings relative to the mounting groove 413, the nose pad cover 430 also swings with the nose pad body 420, allowing the nose pad body 420 to adjust its contact position with the nose. In one embodiment, the nose pad body 420 is configured as a flexible component to improve the comfort of the nose pad module 200 in contact with the nose.

[0078] In an embodiment of the present invention, the nose pad module 200 further includes a locking structure for locking the nose pad body 420 relative to the mounting base 410. Thus, once the nose pad body 420 is adjusted to its correct position, the oscillation stops and is locked in place by the locking structure, preventing discomfort caused by changes in the relative position of the nose pad body 420 and the nose.

[0079] Of course, in other embodiments, the nosepiece body 420 can also be configured as a flexible element. It is understood that a flexible element will deform under a large external force but will not deform under a small external force. When wearing smart glasses, the pushing force of the nose on the nosepiece body 420 cannot cause the flexible element to deform. Thus, the nosepiece body 420 configured as a flexible element does not require a locking structure.

[0080] Please see Figure 6 and Figure 7 In an embodiment of the present invention, the locking structure includes an electromagnet 414 disposed in one of the mounting groove 413 and the connecting portion 422, and a magnetic element 423 disposed in the other of the two. The controller 110 is electrically connected to the electromagnet 414 to control the energization or de-energization of the electromagnet 414, so as to control the attraction or de-attraction between the electromagnet 414 and the magnetic element 423, so as to lock or unlock the swing of the leaf body 420.

[0081] Specifically, in one embodiment, the locking structure is configured as an electromagnetic locking structure. In the embodiment shown in the figures of this invention, an electromagnet 414 is installed on the groove wall of the mounting groove 413, and a magnetic element 423 is provided on the outer side of the connecting portion 422 of the leaf body 420. In one embodiment, the magnetic element 423 is configured as an iron element; of course, in other embodiments, the magnetic element 423 can also be a magnet or a material containing cobalt, nickel, etc.

[0082] When the leaf holder body 420 swings into position, the controller 110 energizes the electromagnet 414, causing it to attract the magnetic component 423, thus limiting the swing of the leaf holder body 420. When the leaf holder body 420 needs to swing within the mounting groove 413 to adjust its position, the controller 110 de-energizes the electromagnet 414, causing it to de-attract from the magnetic component 423, allowing the leaf holder body 420 to swing. It is understood that the leaf holder body 420 can swing relative to the mounting groove 413 within a certain range. To ensure that the electromagnet 414 and the magnetic component 423 can attract each other after the leaf holder body 420 swings to any position, the magnetic component 423 needs to have a certain range. The size of the magnetic component 423 is not limited here.

[0083] Of course, in other embodiments, the mounting groove 413 may be provided with a magnetic element 423, and the leaf holder body 420 may be provided with an electromagnet 414. In other embodiments, the locking structure may also have a first elongated hole in the groove wall of the mounting groove 413 and a second elongated hole in the connecting part 422. When the leaf holder body 420 swings into position, at least part of the first elongated hole and the second elongated hole coincide, and bolts or other connecting parts pass through the first elongated hole and the second elongated hole to lock the swing of the leaf holder body 420.

[0084] In embodiments of the present invention, the swing angle range of the connecting portion 422 relative to the mounting groove 413 is 0-10°. It is understood that, without changing the connecting portion 422, the inclination angle of the groove sidewall of the mounting groove 413 determines the swing range of the connecting portion 422. In one embodiment, the swing angle range of the connecting portion 422 relative to the mounting groove 413 is 0-10°. This ensures the contact area between the connecting portion 422 and the mounting groove 413, thereby ensuring the adsorption area when the electromagnet 414 and the magnetic component 423 attract each other after the leaf body 420 swings to its position, thus ensuring the swing locking effect of the leaf body 420. Of course, in other embodiments, the swing angle range of the connecting portion 422 relative to the mounting groove 413 can also be 0-20°; the swing angle range of the leaf body 420 relative to the mounting groove 413 is not limited here.

[0085] Please see Figure 3 and Figure 6 In an embodiment of the present invention, the frame body 100 is equipped with a control circuit board 120, a controller 110 is disposed on the control circuit board 120, the nose pad leg 300 includes a nose pad wiring harness 330, the nose pad wiring harness 330 is electrically connected to the control circuit board 120; the nose pad body 420 includes a nose pad wiring harness 440, which is located in the mounting base 410, and the nose pad wiring harness 330 is electrically connected to the nose pad wiring harness 440, the electromagnet 414 and the eye sensor 500 respectively.

[0086] Specifically, the frame body 100 is equipped with a control circuit board 120. In one embodiment, the control circuit board 120 includes a main circuit board 121 and a connecting circuit board 122 electrically connected. The main circuit board 121 is provided with a controller 110, and the connecting circuit board 122 includes two connecting pins, each with a connecting wire harness 130 for electrical connection to the left and right nose pads, respectively. The nose pad leg 300 is provided with a nose pad wire harness 330 connected to the connecting wire harness 130, and the nose pad body 420 is provided with a nose pad wire harness 440, with at least a portion of the nose pad wire harness 440 extending from the connecting portion 422 and entering the cavity of the mounting base 410.

[0087] Within the cavity of the mounting base 410, the nose pad wiring harness 330 is electrically connected to the nose pad wiring harness 440, the electromagnet 414, and the eye sensor 500, respectively, to supply power to the nose pad body 420, the electromagnet 414, and the eye sensor 500. In one embodiment, the mounting base 410 includes a base 415 and a mounting cover 416 covering the base 415. The eye sensor 500 is mounted on the mounting cover 416, thus facilitating the installation of the eye sensor 500 and the wiring connections of the nose pad wiring harness 330, the nose pad wiring harness 440, the electromagnet 414, and the eye sensor 500.

[0088] It is worth noting that, Figure 6 and Figure 7 The wiring harness electrical connections shown are merely illustrative and do not represent the actual electrical connections during the operation of the smart glasses. Of course, in other embodiments, each of the aforementioned components may also have its own battery, and they may be electrically connected to each other via electrical signals.

[0089] Please see Figure 6 and Figure 7 In an embodiment of the present invention, a bone conduction sensor 424 is provided in the contact portion 421; and / or, a microphone 425 is provided in the contact portion 421.

[0090] Understandably, the lens assembly 400 incorporates a bone conduction sensor 424 and / or a microphone 425. The basic principle of the bone conduction sensor 424 is to transmit vibrations through the bones, rather than through the air or eardrum. This allows for clear voice capture in noisy environments or uninterrupted reception of ambient sounds during movement, improving safety. The microphone 425 enables the smart glasses to be sound-absorbing, thereby enhancing their functionality.

[0091] 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.
