When the distance between the two nose pads becomes smaller, it will have a lifting movement trend along the user's nose, so that the smart glasses will move upward until the center of the lens of the smart glasses is facing the user's eyeball. Similarly, when it is analyzed that the center of the lens of the smart glasses is higher than the user's eyeball, that is, when the smart glasses are worn too high, the two nose pads can be driven away from each other through the driving mechanism. When the distance between the two nose pads becomes larger, it will have a downward movement trend along the user's nose, so that the smart glasses will move downward until the center of the lens of the smart glasses is facing the user's eyeball. It can be seen that the nose pad adjustment method in this solution achieves automatic corresponding adjustment between the smart glasses and the user's eyes by establishing a connection between the position information of the eyeball and the driving mechanism. In this way, when the user wears the smart glasses, the user's eyes can be kept in alignment with the center of the lens of the smart glasses, thereby reducing the possibility of adverse effects of the smart glasses on the user's eyes.

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0049] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text is to include three parallel solutions. Taking "A and / or B as an example", it includes solution A, or solution B, or a solution that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0051] With the gradual development of augmented reality technology, AR glasses are being used more and more widely. However, there is a common area in which glasses in the current industry need to be improved during use. Specifically, glasses are often worn at different heights due to being lifted too high or slipping during use, making it impossible for the center of the lenses in the glasses to be directly opposite the user's eyeballs. At this time, whether the glasses are worn too high or too low, the user's eyes will need to squint, which can easily cause problems such as eye fatigue or myopic astigmatism, which can easily cause adverse effects on the user's eyes.

[0052] Based on the above considerations, in order to solve the problem that the glasses in the current industry cannot be used directly with the user's eyeballs when worn, which can easily cause adverse effects on the user's eyes, the present application proposes a nose pad adjustment method. The nose pad adjustment method innovatively establishes a connection between the eyeball position information and the driving mechanism used to drive the nose pads to move, so that after comparing the eyeball position information with the standard position information, the driving mechanism is controlled to drive the nose pads to move closer and farther from each other, so as to realize the automatic lifting and lowering of the glasses, and then realize the automatic corresponding adjustment of the glasses and the user's eyeballs, reducing the possibility of adverse effects on the user's eyes due to improper wearing of the glasses.

[0053] Please refer to Figure 1In one embodiment of the present application, the nose pad adjustment method proposed in the present application includes the following steps:

[0054] Step S10, obtaining the position information of the eyeball;

[0055] Step S20, comparing the position information of the eyeball with the standard position information of the eyeball to obtain a position deviation value;

[0056] Step S30 , controlling the driving mechanism 13 to drive the nose pads 15 to move according to the position deviation value, so as to adjust the distance between the two nose pads 15 .

[0057] Among them, after the user or robot wears the smart glasses 100, the position information of the eyeball can be obtained through the position sensor 17 introduced below. The position sensor 17 can be specifically a camera, and the position information of the eyeball can be identified by computer vision image processing technology. Of course, the position sensor 17 can also be an infrared eye tracker, etc. After that, the position information of the eyeball can be compared with the standard position information of the eyeball. The standard position information, that is, when the user or robot wears the smart glasses 100 accurately, the center of the lens of the smart glasses 100 and the eyeball of the user or robot are accurately aligned, and the position of the eyeball of the user or robot at this time is the standard position information. In addition, the standard position information can be pre-stored in the smart glasses 100. After comparing the position information of the eyeball with the standard position information to obtain the deviation value, it means that the current user or robot is not wearing the smart glasses 100 accurately, and the position of the eyeball of the user or robot at the center of the lens of the smart glasses 100 is deviated. Afterwards, the moving distance of the two nose pads 15 is calculated based on the position deviation value until the smart glasses 100 rise when the two nose pads 15 are close to each other, or fall when the two nose pads 15 are far away from each other until the center of the lens is aligned with the eyeball. At this time, the two nose pads 15 can be driven to move a corresponding distance by the driving mechanism 13 used to drive the two nose pads 15 to move. The driving mechanism 13 can be a combination of a driving member 131 and a transmission assembly 132 as described below, or two driving members 131 can drive the two nose pads 15 respectively, so as to ensure that the two nose pads 15 can be driven to adjust the distance between the two nose pads 15.

[0058] When the nose pad adjustment method of the technical solution of the present invention is used, it can automatically obtain the position information of the eyeball, and compare the position information of the eyeball with the standard position information of the eyeball, and then control the driving mechanism 13 to drive the nose pad 15 to move according to the position deviation value obtained by comparison, and then adjust the distance between the two nose pads 15 to achieve the alignment adjustment of the lens center and the eyeball of the smart glasses 100. For example, when it is analyzed that the center of the lens of the smart glasses 100 is lower than the user's eyeball, that is, when the smart glasses 100 are worn too low, the driving mechanism 13 can drive the two nose pads 15 to move closer to each other. When the distance between the two nose pads 15 becomes smaller, it will have a lifting movement trend along the user's nose, so that the smart glasses 100 will move upward until the center of the lens of the smart glasses 100 is facing the user's eyeball. Similarly, when it is analyzed that the center of the lens of the smart glasses 100 is higher than the user's eyeball, that is, when the smart glasses 100 are worn too high, the driving mechanism 13 can drive the two nose pads 15 away from each other. When the distance between the two nose pads 15 increases, it will have a downward movement trend along the user's nose, thereby causing the smart glasses 100 to move downward until the center of the lens of the smart glasses 100 faces the user's eyeball. It can be seen that the nose pad adjustment method in this solution realizes automatic corresponding adjustment between the smart glasses 100 and the user's eyeball by establishing a connection between the position information of the eyeball and the driving mechanism 13. In this way, when the user wears the smart glasses 100, the user's eyeball can be kept facing the center of the lens of the smart glasses 100, so as to reduce the possibility of the smart glasses 100 causing adverse effects on the user's eyes.

[0059] Further, based on the nose pad adjustment method of the above embodiment, please refer to Figure 2 In one embodiment of the present application, the step of obtaining the current position information of the eyeball includes the following steps:

[0060] Step S11, obtaining a visual image of the eyeball;

[0061] Step S12, obtaining the position information of the eyeball according to the visual image analysis.

[0062] In this embodiment, the smart glasses 100 can take a picture of the user's or robot's eyeballs through a camera as described below, and then obtain a visual image of the eyeball position when currently worn. The glasses can pre-store a standard position image when the center of the lens of the glasses is directly opposite to the user's eyeball. In this way, by comparing the eyeball visual image with the standard position image information, the smart glasses 100 can identify the user's eyeball position information based on computer vision image processing technology (since the technology of identifying position information by shooting images is an existing technology, it will not be described in detail here), and then determine whether the current smart glasses 100 are worn too high or too low. At this time, since a camera is needed to implement the method, and the camera is relatively small in size, and does not need to be used in combination, the components are single, which is conducive to improving the convenience of setting it in the limited space on the frame 11.

[0063] Next, the specific structure of the nose pad adjustment structure 10 that can realize the above-mentioned nose pad adjustment method is explained. The nose pad adjustment structure 10 proposed in this application is applied to smart glasses 100, and the smart glasses include a frame 11. In one embodiment of this application, please refer to Figures 3 to 6 The frame assembly 10 proposed in the present application includes two nose pads 15, a driving mechanism 13, and a position sensor 17. The two nose pads 15 are used to be arranged on the frame 11; the driving mechanism 13 is used to be arranged on the frame 11 and can drive the two nose pads 15 to move so as to adjust the distance between the two nose pads 15; the position sensor 17 is used to identify the position information of the eyeball and control the driving mechanism 13 based on the position information of the eyeball.

[0064] The frame 11 can serve as the main frame structure of the smart glasses 100, so as to install components such as the driving mechanism 13, the nose pad 15 and the lenses. At the same time, it can also be used to connect the temples 30 in the smart glasses 100. The frame 11 can be a structure formed by combining two closed annular parts, or can be a structure formed by combining two unclosed annular parts. The present application does not limit the specific structure of the frame 11, and it can be used to install components such as the driving mechanism 13, the nose pad 15 and the lenses.

[0065] The nose pad 15 can be used to abut against the user's nose, and then after the user wears the smart glasses 100, the abutment support of the nose pad 15 can improve the wearing stability of the smart glasses 100. The nose pad 15 can be in a semicircular block shape, or in a cam shape, etc., which is not limited in this application.

[0066] The driving mechanism 13 can be used to provide a driving force to drive the two nose pads 15 to move closer to and away from each other, so that when the two nose pads 15 move closer to each other, they can have a tendency to move upward along the user's nose to achieve the lifting of the smart glasses 100; and when the two nose pads 15 move away from each other, they can have a tendency to move downward along the user's nose to achieve the lowering of the smart glasses 100. In this way, by adjusting the distance between the two nose pads 15, the wearing height of the smart glasses 100 can be adjusted, thereby achieving the corresponding adjustment of the center of the lens of the smart glasses 100 and the user's eyeball. Among them, the driving mechanism 13 can be a combination of a driving member 131 and a transmission assembly 132 as described below, so that the two nose pads 15 are driven by one driving member 131; of course, it can also directly include two driving members 131, so that the two nose pads 15 are driven by the two driving members 131 respectively. The present application does not limit the structural type of the driving mechanism 13 , and the driving mechanism 13 can also be set at any position of the frame 11 , ensuring that the driving mechanism 13 can provide a driving force to drive the two nose pads 15 to move closer to or away from each other.

[0067] The position sensor 17 can be used to identify the position information of the user's eyeballs and transmit it to the driving mechanism 13, so that the driving mechanism 13 drives the nose pads 15 to move to adjust the wearing height of the smart glasses 100, until the center of the lens of the smart glasses 100 is facing the user's eyeballs. Among them, the position sensor 17 can be a camera as described below, of course, it can also be an infrared eye tracker, etc., and this application is not limited to this. As long as the position information of the user's eyeballs can be identified, the driving mechanism 13 drives the nose pads 15 to adjust the wearing height of the smart glasses 100 to the right position. In addition, the position sensor 17 can be connected to a control board, so that after the position information of the eyeball is given, the driving mechanism 13 can be controlled to work.

[0068] When the nose pad adjustment mechanism 10 of the technical solution of the present application is applied to the smart glasses 100, since a position sensor 17 is provided on the frame 11 in the frame assembly 10, the position information of the user's eyeball can be identified through the position sensor 17. At this time, when it is identified that the center of the lens of the smart glasses 100 is lower than the user's eyeball, that is, when the smart glasses 100 are worn too low, the position sensor 17 can transmit the identified position information to the driving mechanism 13, and the driving mechanism 13 can drive the two nose pads 15 to approach each other. When the distance between the two nose pads 15 becomes smaller, it will have a lifting movement trend along the user's nose, thereby causing the smart glasses 100 to move upward until the center of the lens of the smart glasses 100 is facing the user's eyeball. Similarly, when it is identified that the center of the lens of the smart glasses 100 is higher than the user's eyeball, that is, when the smart glasses 100 are worn too high, the position sensor 17 can also transmit the identified position information to the driving mechanism 13, and the driving mechanism 13 can drive the two nose pads 15 to move away from each other. When the distance between the two nose pads 15 increases, it will have a downward movement trend along the user's nose, thereby causing the smart glasses 100 to move downward until the center of the lens of the smart glasses 100 faces the user's eyeball. It can be seen that the nose pad adjustment mechanism in this solution realizes automatic corresponding adjustment between the smart glasses 100 and the user's eyeball through the combination of the position sensor 17 and the drive mechanism 13. In this way, when the user wears the smart glasses 100, the user's eyeball can be kept facing the center of the lens of the smart glasses 100, so as to reduce the possibility of the smart glasses 100 causing adverse effects on the user's eyes.

[0069] Please refer to Figures 5 to 7 In one embodiment of the present application, the driving mechanism 13 includes a driving member 131 and a transmission assembly 132; the transmission assembly 132 is connected to the driving member 131 and the two nose pads 15, so that the driving member 131 drives the two nose pads 15 to move closer to and away from each other through the transmission assembly 132.

[0070] The driving member 131 can be used as a power source to increase the driving force required for movement. The transmission assembly 132 can be used to transmit the drive of the driving member 131 to the two nose pads 15, thereby driving the two nose pads 15 to move closer to each other. The driving member 131 can be a motor or a rotary cylinder. The transmission assembly 132 can be a gear 133 and two racks 134 as described below, or of course a bidirectional screw rod. The present application does not limit the specific types of the driving member 131 and the transmission assembly 132.

[0071] In this embodiment, the driving mechanism 13 is configured to include a driving member 131 and a transmission assembly 132, so that one driving member 131 can provide power to drive two nose pads 15 at the same time. In this case, the number of driving members 131 required can be reduced, and the power consumption required by the driving mechanism 13 when working can be reduced, which is conducive to improving the working time of the smart glasses 100 and improving the user experience. At the same time, such a configuration also makes the structure of the driving mechanism 13 relatively simple, which can improve the convenience of its installation in the limited space on the frame 11.

[0072] Please refer to Figures 6 to 8 In one embodiment of the present application, the transmission assembly 132 includes a gear 133 and two racks 134, the gear 133 is connected to the driving member 131, and the axis of the gear 133 is perpendicular to the sliding direction of the nose pad 15; the two racks 134 are respectively engaged with the opposite sides of the gear 133, and one rack 134 is connected to one nose pad 15.

[0073] When the gear 133 is driven by the driving member 131 to rotate in one direction, the two racks 134 can be driven to approach each other, thereby achieving the mutual approach of the nose pads 15 connected to the two racks 134. When the gear 133 is driven to rotate in the opposite direction, the two racks 134 can be driven to move away from each other, thereby achieving the mutual movement of the nose pads 15 connected to the two racks 134.

[0074] In this embodiment, the transmission assembly 132 is configured to include a gear 133 and two racks 134, and the gear 133 transmission has the advantages of simple structure and stable transmission, so that the synchronous driving of the two nose pads 15 can be realized more conveniently, and the driving stability of the nose pads 15 can be realized. Moreover, it is particularly important that the racks 134 are meshed with the opposite sides of the gear 133, so that they can be distributed more compactly, thereby facilitating the reduction of the overall volume of the transmission assembly 132, so that it can be better installed and set in the limited space on the frame 11. Of course, in other embodiments, the transmission assembly 132 includes a bidirectional screw and two sliding members, the two sliding members are sleeved on the two threaded sections of the bidirectional screw, and are respectively connected to the two nose pads 15, so that the two sliding members are driven to move closer to and away from each other by the bidirectional screw when rotating, thereby driving the two nose pads 15 to move closer to and away from each other.

[0075] Please refer to Figures 6 to 8In one embodiment of the present application, the rack 134 includes a first section 135 and a second section 136. The first section 135 extends along the sliding direction of the nose pad 15. The first section 135 is provided with meshing teeth 135a, and the meshing teeth 135a are meshed with the gear 133. One end of the second section 136 is connected to the first section 135, and the other end is connected to the nose pad 15. The second section 136 and the first section 135 are arranged at an angle.

[0076] The first segment 135 can be extended in the horizontal direction to mesh with the gear 133 for transmission. The second segment 136 can be arranged in an inclined downward direction to connect with the nose pad 15. The first segment 135 and the second segment 136 can be an integral structure to improve the connection strength of the two at the connection point, thereby facilitating the overall strength of the rack 134 for stable transmission of the rack 134. At the same time, the rack 134 can be manufactured by integral molding, thereby simplifying the assembly steps of the first segment 135 and the second segment 136, thereby facilitating the production efficiency of the rack 134.

[0077] In this embodiment, the rack 134 is configured to include a first segment 135 and a second segment 136 that are arranged at an angle, so that the first segment 135 can be arranged very close to the gear 133, thereby facilitating the meshing of the two; and the second segment 136 can also be arranged relatively close to the nose pad 15, thereby facilitating the connection between the two. Therefore, the structure of the rack 134 is configured in this way, so that it can be relatively convenient to establish the required connection with the gear 133 and the nose pad 15, and fully utilize the limited space on the frame 11, so that the rack 134 will not interfere with the arrangement of the lens installed on the frame 11. Of course, in other embodiments, when the connecting portion 115 has a relatively high height in the vertical direction, the rack 134 only includes the first segment 135, and the middle part of the first segment 135 is meshed with the gear 133, and the end part is connected to the nose pad 15.

[0078] Please refer to Figures 6 to 8 In one embodiment of the present application, the transmission assembly 132 also includes a worm wheel 137 and a worm 138. The worm wheel 137 and the gear 133 are coaxially arranged and can drive the gear 133 to rotate when rotating; the worm 138 is connected to the driving member 131 and meshes with the worm wheel 137.

[0079] The worm 138 can be driven to rotate by the driving member 131, and the worm wheel 137 is meshed with the worm 138, so when the worm 138 rotates, the worm wheel 137 can be driven to rotate. When the worm wheel 137 rotates, it can drive the gear 133 to rotate, thereby realizing the subsequent driving of the rack 134 and the nose pad 15 connected to the rack 134. Among them, the worm wheel 137 can be directly connected to the gear 133. Of course, the transmission component 132 can also include a mounting shaft 140 rotatably arranged on the connecting part 115, and the mounting shaft 140 can be used as a mounting carrier to install the gear 133 and the worm wheel 137, and then when the worm wheel 137 rotates to drive the mounting shaft 140 to rotate, it can drive the gear 133 installed on the mounting shaft 140.

[0080] In this embodiment, a worm wheel 137 and a worm 138 are further provided in the transmission assembly 132, so that the rotation axis of the driving member 131 does not need to be parallel to the axis of the gear 133. That is, the gear 133 and the driving member 131 will not be stacked in the thickness direction of the frame 11 (that is, the axis direction of the gear 133), and thus the convenience of installing and setting the driving member 131 can be improved in the case of limited space in the thickness direction of the frame 11. Of course, it should be noted that in other embodiments, when the frame 11 has a relatively large thickness, the transmission assembly 132 is not provided with the worm wheel 137 and the worm 138, and the driving member 131 can be directly connected to the gear 133.

[0081] Please refer to Figure 4 , Figure 6 , Figure 7 as well as Figure 8 In one embodiment of the present application, the sliding direction of the nose pad 15 is defined as the horizontal direction, the frame assembly 10 also has an up-down direction perpendicular to the horizontal direction, and the axis of the worm 138 is set at an angle to both the horizontal direction and the up-down direction.

[0082] In this embodiment, the axis of the worm 138 is set at an angle to the horizontal direction and the vertical direction, so that the driving member 131 connected to the worm 138 can also be set at an angle. In this case, the driving member 131 can be set above the rack 134, so that the driving member 131 and the rack 134 do not need to be stacked in the thickness direction of the frame 11, which is conducive to further improving the compactness of the arrangement of the driving member 131 and the transmission assembly 132, so that in the case of limited space in the thickness direction of the frame 11, the convenience of installing the driving member 131 can be further improved.

[0083] In one embodiment of the present application, the position sensor 17 is a camera.

[0084] In this embodiment, the position sensor 17 is set as a camera, so that the user's eyeball can be photographed by the camera, and then a visual image of the eyeball position when currently worn can be obtained. The smart glasses 100 can pre-store a visual image of the standard position when the center of the lens of the smart glasses 100 is directly opposite to the user's eyeball. In this way, by comparing the current eyeball position visual image with the standard position visual image, the smart glasses 100 can identify the user's eyeball position information based on computer vision image processing technology (since the technology of identifying position information by shooting images is an existing technology, it will not be described in detail here), and then determine whether the current smart glasses 100 are worn too high or too low. At this time, since the size of the camera is relatively small and there is no need to use it in combination, the parts are single, which is conducive to improving the convenience of setting it in the limited space on the frame 11.

[0085] Please refer to Figure 2 The present application also proposes a pair of smart glasses 100, which includes a frame 11 and a nose pad adjustment structure 10. The specific structure of the nose pad adjustment structure 10 refers to the above embodiment. Since the smart glasses 100 adopts all the technical solutions of all the above embodiments, they at least have all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. Among them, the nose pad 15, the driving mechanism 13 and the position sensor 17 in the nose pad adjustment structure 10 are all arranged on the frame 11.

[0086] In one embodiment of the present application, the frame 11 is provided with two lens mounting holes 115 in the moving direction of the nose pad 15 (the lens mounting holes 115 are used to mount the lenses of the smart glasses 100), the number of the position sensors 17 is two, the two position sensors 17 are both electrically connected to the driving mechanism, and each position sensor 17 is arranged above a lens mounting hole 115.

[0087] In this embodiment, the number of position sensors 17 is set to two, and they are respectively located above the two lens mounting holes 115 on the frame 11, so that the two position sensors 17 can respectively correspond to the two eyes of the user well, thereby facilitating the position sensor 17 to identify the position information of the two eyeballs of the user, so as to improve the accuracy of the position information identification and improve the accuracy of the subsequent corresponding adjustment of the center of the lens of the glasses 100 and the user's eyeball. Of course, the present application is not limited to this. In other embodiments, the number of position sensors 17 can be set to only one, or three or more, so as to reduce the error and improve the accuracy of identification through the average of the position information identified by multiple position sensors 17.

[0088] Please refer to Figures 3 to 6In one embodiment of the present application, a receiving cavity 191 is provided in the frame 11, the driving mechanism 13 is provided in the receiving cavity 191, and two nose pads 15 are provided on the outside of the frame 11; the frame 11 is also provided with a clearance hole 116 connected to the receiving cavity 191, the clearance hole 116 is extended along the sliding direction of the nose pad 15, the driving mechanism 13 is connected to one end of the nose pad 15 and / or one end of the nose pad 15 connected to the driving mechanism 13 passes through the clearance hole 116; the position sensor 17 is provided in the receiving cavity and partially passes through the frame 11.

[0089] In this embodiment, the drive mechanism 13 can be arranged in the accommodating cavity 191 by setting the accommodating cavity 191. At this time, the cavity wall of the accommodating cavity 191 can isolate and protect the drive mechanism 13, so that the drive mechanism 13 can be protected from damage by foreign objects. At the same time, by hiding the drive mechanism 13, the visual experience given by the frame 11 can also be improved, so as to further improve the user's experience. The part of the position sensor 17 is arranged in the accommodating cavity 191, which can also play a certain isolation and protection role and improve the compactness of the installation. At the same time, the part of the position sensor 17 that passes through the frame 11 can also be directly exposed, thereby facilitating the detection of whether the user is wearing glasses 100. The clearance hole 116 on the frame 11 can be used for the drive mechanism 13 to be connected to one end of the nose pad 15, or the nose pad 15 to be connected to one end of the drive mechanism 13, or the end of the drive mechanism 13 connected to the nose pad 15 and the end of the nose pad 15 to be connected to the drive mechanism 13, so as to realize the connection between the drive mechanism 13 located in the accommodating cavity 191 and the nose pad 15 located outside the accommodating cavity 191. The drive mechanism 13 can further include a fastener 139, which can pass through the second section 136 of the rack 134 in the drive mechanism 13 and be connected to the nose pad 15 after extending out of the clearance hole 116. Specifically, the fastener 139 can be a screw, so that the connection between the nose pad 15 and the rack 134 is relatively simple, which is conducive to improving the convenience of assembling the glasses 100. Moreover, at this time, the nose pad 15 and the rack 134 are also detachably connected, so that when both are damaged, they can be disassembled and repaired. Of course, the fastener 139 can also be an ordinary column, and after passing through the pass hole 116, it is adhesively connected or magnetically connected to the nose pad 15. In addition, the pass hole 116 can also guide the fastener 139, thereby guiding the sliding of the nose pad 15, so as to further improve the stability of the nose pad 15 during the sliding process. The position sensor 17 is arranged on the outside of the frame 11, so that it can be directly exposed to work, thereby facilitating the accurate position information of the user's eyeball. At the same time, such a setting also makes it convenient to repair and replace it when it is damaged. In addition, in order to improve the convenience of processing and forming the accommodating cavity 191, the frame 11 may include a first shell 117 and a second shell 118, and the first shell 117 and the second shell 118 enclose the accommodating cavity 191.
