Description

TECHNICAL FIELD

[0001] Embodiments of the present disclosure relate to the technical field of head-mounted display device, in particular to a glasses rotation shaft and smart glasses with the same. BACKGROUND

[0002] In the technical field of head-mounted display device, AR glasses can construct a virtual visual picture in a space of several meters in front of the glasses. However, due to the constraint of optical aperture, the visual area formed around the human eye has a range limit, which is defined as the eye-box. The user's eyes need to be within the range of the eye-box to see the imaging picture. The commonly used method to adjust the eye-box to the position of the user's eyes is to adjust the height of the glasses nose pad.

[0003] However, when the above-mentioned method of adjusting the height of the glasses nose pad is adopted, the following technical problems often exist:

[0004] With the change of the height of the nose pad, although the eyes can enter the range of the eye-box, it will cause the change of the viewing angle of the imaging picture of the AR glasses, which may cause the picture missing, thereby affecting the use experience.

Moreover, the sliding block is embedded in the shaft housing, which can change the included angle between the shaft housing and the XOY plane, thereby enabling the temple to be adjusted in the vertical direction. Thus, the use experience of AR glasses can be improved. BRIEF DESCRIPTION OF DRAWINGS

[0046] Figure 12 is a comparison diagram of the states of the temple before and after adjustment of some embodiments of the present disclosure. Figure 12 The XOZ plane 30, the frame 31 and the temple 16 are included. It should be noted that the frame 31 is placed parallel to the XOZ plane 30. Among them, the XOZ plane 30 is based on the coordinate system shown in Figure 1 The temple 16 includes the forms in the two states before and after adjustment, and the two states do not coexist. In the figure, the forms in the two states are combined in the same picture only for the convenience of understanding. The arrow in the figure points from the temple before adjustment to the temple after adjustment.

[0047] In some embodiments, the above-mentioned glasses hinge can include a slider 1, a hinge shell 3, a hinge inner shell 2, a connecting piece 4 and a first elastic piece 19. Among them, the above-mentioned slider 1 can be a hollow structure similar to a cuboid. One side of the above-mentioned slider 1 can be provided with a slider tooth belt 17. The above-mentioned slider tooth belt 17 can be a sawtooth-shaped protruding belt that has been pre-set on one side of the above-mentioned slider 1. The above-mentioned hinge inner shell 2 can be a cuboid structure provided with an inner shell tooth belt 18 on one side. The above-mentioned inner shell tooth belt 18 can be a sawtooth-shaped protruding belt that has been pre-set on one side of the above-mentioned hinge inner shell 2. The above-mentioned slider tooth belt 17 and the above-mentioned inner shell tooth belt 18 are separable intermeshing structures. The above-mentioned first elastic piece 19 can abut the above-mentioned slider 1 and the above-mentioned hinge inner shell 2, respectively. One end of the above-mentioned first elastic piece 19 abuts against the side of the above-mentioned slider 1 which is not provided with the above-mentioned slider tooth belt 17, and the other end abuts against the side of the above-mentioned hinge inner shell 2 which is provided with the above-mentioned inner shell tooth belt 18. The above-mentioned first elastic piece 19 can make the above-mentioned slider 1 and the above-mentioned hinge inner shell 2 receive a set of forces of the same size and opposite directions through the elastic force of the first elastic piece 19. This can make the elastic force of the above-mentioned first elastic piece 19 be converted into the fastening force of the intermeshing of the above-mentioned slider tooth belt 17 and the above-mentioned inner shell tooth belt 18. When the above-mentioned first elastic piece 19 is compressed, the above-mentioned slider tooth belt 17 and the above-mentioned inner shell tooth belt 18 are separated. For example, the user can pull the above-mentioned slider 1 with his hand so that the above-mentioned first elastic piece 19 is compressed, and at the same time, the above-mentioned slider tooth belt 17 and the above-mentioned inner shell tooth belt 18 are separated. At this time, the user can give the above-mentioned slider 1 a downward or upward force, so that the above-mentioned slider tooth belt 17 rotates around the above-mentioned inner shell tooth belt 18. When the appropriate angle is reached, the user releases his hand, and the above-mentioned first elastic piece 19 makes the above-mentioned slider tooth belt 17 and the above-mentioned inner shell tooth belt 18 re-intermesh. The above-mentioned first elastic piece 19 can be a compression spring, which is not specifically limited here. The above-mentioned slider 1 and the above-mentioned hinge inner shell 2 can be plastic materials, which are not specifically limited here.

[0048] In some embodiments, the first elastic member 19 can also abut against the slider 1 and the shaft housing 3 respectively to achieve the meshing of the slider tooth belt 17 and the inner housing tooth belt 18. The specific structure design can be as follows: a housing protrusion is arranged inside the shaft housing 3. The housing protrusion can be a square protrusion. It should be noted that the housing protrusion is not shown in the drawings. The first elastic member 19 is installed on the back of the housing protrusion and the slider tooth belt 17, so that the first elastic member 19 abuts against the slider 1 and the shaft housing 3 respectively to achieve the meshing of the slider tooth belt 17 and the inner housing tooth belt 18. For ease of understanding, the following explanation is made in combination with the coordinate system in the drawings. Figure 1 The housing protrusion is arranged in the positive direction of the Y-axis of the slider 1. For example, if the maximum coordinate value of the edge of the slider 1 on the Y-axis is 10, the housing protrusion can be arranged at a position with a Y-axis coordinate value of 15.

[0049] In some embodiments, the slider 1 can be embedded inside the shaft housing 3. The shaft housing 3 can be a sheet-shaped structure with bent edges on both sides. The shaft housing 3 can be used to wrap the components of the slider 1 and the shaft inner housing 2. The shaft housing 3 wrapping the slider 1 and the shaft inner housing 2 can protect the connection relationship between the slider 1 and the shaft inner housing 2 to some extent. The material of the shaft housing 3 can be metal (such as titanium alloy) or plastic (such as polycarbonate), which is not limited here. The shaft housing 3 can be provided with a temple 16, that is, the shaft housing 3 and the temple 16 are an integral structure. It can also be a split structure, which requires a connecting structure on the shaft housing 3 to connect the temple 16. Whether the shaft housing 3 and the temple 16 are integral or not is not limited here. The shaft housing 3 can be connected to the shaft inner housing 2 through the connecting member 4. The connecting member 4 can be a screw, which is not limited here. The shaft housing 3 can be provided with a screw hole for installing the screw. The shaft inner housing 2 can be provided with a hole larger than the diameter of the rod of the screw but smaller than the diameter of the head of the screw. In this way, the rod of the screw can be screwed into the screw hole of the shaft housing 3 through the hole of the shaft inner housing 2. Because the screw and the shaft housing 3 are fixed through the screw hole, the screw and the shaft housing 3 can be regarded as a whole. The hole of the shaft inner housing 2 is larger than the diameter of the rod of the screw. Therefore, the screw can move in the hole of the shaft inner housing 2. Further, the shaft housing 3 and the shaft inner housing 2 can slide relative to each other within a predetermined range. The predetermined range is the range of the hole of the shaft inner housing 2.

[0050] In some embodiments, when the slider tooth belt 17 and the inner shell tooth belt 18 are in meshing rotation, the angle between the rotation shaft shell 3 and the XOY plane changes. The meshing rotation of the slider tooth belt 17 and the inner shell tooth belt 18 refers to the change of the relative position between the slider tooth belt 17 and the inner shell tooth belt 18. For example, assuming that the temple 16 is an integral structure with the rotation shaft shell 3, the temple 16 can be regarded as an extension of the rotation shaft shell 3. If the slider tooth belt 17 is moved downward by one tooth, the angle between the rotation shaft shell 3 and the XOY plane increases by 15°, and then the temple 16 is vertically adjusted downward by 15°. It should be noted that, Figure 1 and Figure 4 The rotation shaft shell 3 shown in the above is not provided with the temple 16. The specific angle that can be changed by adjusting the slider tooth belt 17 and the inner shell tooth belt 18 is not limited. The significance of vertically adjusting the angle of the temple 16 is that the user can compensate for the change of the picture viewing angle caused by adjusting the nose pad in combination with the angle adjustment of the temple 16. For example, although the elevation of the nose pad makes the eyes enter the eye box, it also causes the picture to be offset upward, at this time, the temple 16 is rotated upward by a certain angle, which drives the frame to slightly tilt downward, so that the picture viewing angle returns to the normal range, and at the same time, the clamping force of the glasses is also enhanced to a certain extent, which ensures the stability of wearing. Moreover, the vertical adjustment of the temple 16 by changing the meshing teeth of the slider tooth belt 17 and the inner shell tooth belt 18 can improve the stability of the temple 16 after vertical angle adjustment, so that the temple 16 will not easily rotate vertically again. To a certain extent, it can improve the user experience, which is reflected in that the user does not need to adjust again the next time he uses it after adjusting it once.

[0051] Alternatively, as shown in Figure 4 The rotation shaft shell 3 can be provided with a connecting part 15. The connecting part 15 can be a protrusion with an internal hollow and a thread. Figure 2 The rotation shaft inner shell 2 shown in the above can be provided with a connecting hole 12, and the diameter of the connecting hole 12 can be greater than Figure 1 The diameter of the connecting part 4. The connecting part 4 can be a gasket screw. The diameter of the connecting hole 12 can be greater than the diameter of the gasket screw rod part and the head part. The diameter of the connecting hole 12 can be smaller than the gasket diameter of the gasket screw. Referring to Figure 1The rod of the gasket screw can pass through the connecting hole 12 and be screwed into the connecting part 15 to be connected with the rotating shaft shell 3 as a whole. The gasket of the gasket screw is installed at the end of the head of the gasket screw to prevent the head of the gasket screw from passing through the connecting hole 12. Because the diameter of the rod of the gasket screw is smaller than the diameter of the connecting hole 12, the rod of the gasket screw can move in the connecting hole 12, so that the rotating shaft shell 3 and the rotating shaft inner shell 2 can slide relative to each other. Because the rod of the gasket screw is screwed into the connecting part 15, the connecting part 4 can move synchronously with the rotating shaft shell 3. The gasket screw is used because the gasket screw can compensate for the small diameter of the head of the screw and reduce the possibility of the head of the screw sinking into the connecting hole 12. In addition, the relative sliding of the rotating shaft shell 3 and the rotating shaft inner shell 2 is prevented to a certain extent. Figure 12 When the plane of the mirror frame 31 is parallel to the XOZ plane 30, the rotating shaft shell 3 can drive the temple 16 to rotate in the YOZ plane through the connecting part 4, so that the angle between the temple 16 and the XOY plane changes.

[0052] Alternatively, as shown in Figure 6 The opposite side of the sliding block tooth belt 17 is provided with a sliding block protrusion 10. The sliding block protrusion 10 can be a square protrusion structure. On the rotating shaft inner shell 2, the side of the inner shell tooth belt 18 can be provided with a sliding block protrusion 10. Figure 2The inner housing protrusion 11 is shown. The inner housing protrusion 11 can be located on the side of the inner housing tooth belt 18 and perpendicular to the tooth tip of the inner housing tooth belt 18. The inner housing protrusion 11 can be a square protrusion. The slider protrusion 10 and the inner housing protrusion 11 sandwich the first elastic member 19, so that one side of the first elastic member 19 is against the slider protrusion 10, and the other side is against the inner housing protrusion 11. The reason for this arrangement is that the first elastic member 19 (such as a compression spring) releases elastic force to both sides after being compressed. The elastic force of the first elastic member 19 can be used to provide a fastening force for the meshing of the slider tooth belt 17 and the inner housing tooth belt 18. This is achieved by the slider protrusion 10 and the inner housing protrusion 11. The principle is that the distance between the slider protrusion 10 and the inner housing protrusion 11 is smaller than the length of the first elastic member 19 when it is not deformed. After the first elastic member 19 is compressed, it is placed between the slider protrusion 10 and the inner housing protrusion 11. The first elastic member 19 presses the slider protrusion 10 and the inner housing protrusion 11 on both sides. Because the slider tooth belt 17 and the inner housing tooth belt 18 are meshed with each other, the slider protrusion 10 and the inner housing protrusion 11 cannot move. Thus, the elastic force of the first elastic member 19 can be converted into a fastening force for the slider tooth belt 17 and the inner housing tooth belt 18.

[0053] Optionally, as shown in Figure 1 and Figure 7 , the upper end of the shaft housing 3 can be provided with an upper baffle 5, and the lower end can be provided with a lower baffle 6. The upper baffle 5 and the lower baffle 6 can be a sheet structure obtained by bending a portion of the opposite sides of the shaft housing 3. The upper baffle 5 and the lower baffle 6 can better wrap the slider 1 and the shaft inner housing 2. To some extent, it protects the cooperation relationship of the slider 1 and the shaft inner housing 2. The shaft inner housing 2 can be rotatably connected to the glasses body 9. It should be noted that the rotatable connection to the glasses body 9 here means that the shaft inner housing 2 can rotate around the glasses body 9 in the same plane. For example, in combination with Figure 1 the coordinate system shown, after the glasses body 9 and the shaft inner housing 2 are connected, they are placed in the XOY plane, and the angle between the shaft inner housing 2 and the glasses body 9 in the XOY plane can be changed. The slider 1 can move between the upper baffle 5 and the lower baffle 6 to achieve the separable meshing of the slider tooth belt 17 and the inner housing tooth belt 18.

[0054] Optionally, as shown in Figure 5 , the temple 16 can be detachably connected to the shaft housing 3. It should be noted that Figure 5The mirror legs 16 are connected to the rotating shaft shell 3. The mirror legs 16 can be in a long strip structure. One side of the mirror legs 16 can be provided with an arc-shaped bend. The arc-shaped bend can be used to hook behind the user's ear to fix the lenses of the glasses in front of the user's eyes. The other side of the mirror legs 16 can be provided with a buckle. The rotating shaft shell 3 can be provided with a buckle matched with the buckle on the mirror legs 16. The embedding of the buckle can make the mirror legs 16 detachably connected to the rotating shaft shell 3. The detachable connection of the mirror legs 16 to the rotating shaft shell 3 facilitates the storage and carrying of the glasses as a whole to a certain extent.

[0055] Optionally, the slider tooth belt 17 and the inner shell tooth belt 18 are configured to be separable engagement structure. The specific implementation has been explained above, which will not be repeated here.

[0056] Optionally, as shown in Figure 1 and Figure 7 , the lower baffle 6 of the rotating shaft shell 3 is provided with an opening. The opening can pass through the rotating shaft inner shell 2. When the rotating shaft shell 3 is adjusted upward, the rotating shaft inner shell 2 moves vertically downward compared with the rotating shaft shell 3. The lower baffle 6 of the rotating shaft shell 3 blocks the path of the downward movement of the rotating shaft inner shell 2. Therefore, an opening needs to be provided on the lower baffle 6 of the rotating shaft shell 3 to pass through the rotating shaft inner shell 2.

[0057] Optionally, as shown in Figure 6 , the number of teeth of the slider tooth belt 17 can be greater than the number of teeth of the inner shell tooth belt 18. Because the slider tooth belt 17 and the inner shell tooth belt 18 need to be dislocated when the vertical angle of the mirror legs is adjusted. The number of teeth of the slider tooth belt 17 is greater than the number of teeth of the inner shell tooth belt 18, which makes the slider tooth belt 17 and the inner shell tooth belt 18 have space to be dislocated.

[0058] Further referring to Figure 8 , Figure 8 is a structure schematic diagram of the adjustable mirror legs of some embodiments of the present disclosure in an incomplete assembled state. Figure 8 It includes a rotating shaft shell 3, a fixed segment 20, a movable segment 21, a threaded groove 22, a screw rod 23, and an adjusting knob 24.

[0061] Optionally, the above-mentioned glasses rotation shaft can further comprise an adjustable temple. The above-mentioned adjustable temple is a temple with adjustable length. The above-mentioned adjustable temple can comprise a fixed segment 20 and a movable segment 21. The above-mentioned fixed segment 20 is a long strip structure.

It should be noted that in Figure 8 , the threads of the above-mentioned screw rod 23 and the above-mentioned threaded groove 22 are not drawn. The above-mentioned screw rod 23 can match the above-mentioned threaded groove 22. The above-mentioned fixed segment 20 can be detachably connected to the above-mentioned rotation shaft shell 3 through the above-mentioned screw rod 23 and the above-mentioned threaded groove 22. The other side of the above-mentioned fixed segment 20 can be provided with a sliding groove 27 from the end face to the inside. The above-mentioned sliding groove 27 is a long strip groove provided inside the above-mentioned fixed segment 20. One side of the inside of the above-mentioned sliding groove 27 can be provided with a first toothed belt 25. The above-mentioned first toothed belt 25 can be a belt structure composed of a plurality of sawteeth. One side of the above-mentioned movable segment 21 can be provided with a connecting rod 28. The one side of the above-mentioned movable segment 21 refers to the side without the arc-shaped bend. The above-mentioned connecting rod 28 can be a rod-shaped structure with a second toothed belt 29. The above-mentioned second toothed belt 29 can be a belt structure with the same shape as the above-mentioned first toothed belt 25. The above-mentioned connecting rod 28 can be installed in the above-mentioned sliding groove 27, and the above-mentioned second toothed belt 29 is opposite to the above-mentioned first toothed belt 25. The above-mentioned second toothed belt 29 and the above-mentioned first toothed belt 25 can be provided with a gap therebetween. The outer surface of the above-mentioned fixed segment 20 can be provided with a hole. The above-mentioned hole can be arranged at a position opposite to the above-mentioned gap. The above-mentioned hole can be provided with an adjusting knob 24. The above-mentioned adjusting knob 24 can be provided with a gear. It should be noted that the adjusting knob 24 shown in Figure 8 does not have a gear. The above-mentioned gear can match the above-mentioned gap. That is, the above-mentioned gear can be inserted into the above-mentioned gap, and the teeth of the above-mentioned gear can engage with the above-mentioned first toothed belt 25 and the above-mentioned second toothed belt 29. When the above-mentioned adjusting knob 24 is rotated, the above-mentioned first toothed belt 25 and the above-mentioned second toothed belt 29 will be relatively displaced. For example, when the above-mentioned adjusting knob 24 is rotated clockwise, the above-mentioned second toothed belt 29 will move towards the above-mentioned rotation shaft shell 3, thereby driving the above-mentioned movable segment 21 to move in the direction of approaching the above-mentioned rotation shaft shell 3, so as to achieve the effect of shortening the above-mentioned adjustable temple. The thickness of the above-mentioned gear can be greater than the width of the above-mentioned first toothed belt 25 and the above-mentioned second toothed belt 29. In the above-mentioned sliding groove 27, the side opposite to the above-mentioned hole can be provided with a gear groove 26. It should be noted that the gear groove 26 shown in Figure 9 is not the profile of the gear, Figure 9The gear recess 26 shown in the figure is only a schematic of the location and general shape of the gear recess 26. The gear recess 26 can be a recess provided on an inner wall of the sliding groove 27 and matching the gear profile. The thickness of the gear is set to be greater than the width of the first tooth belt 25 and the second tooth belt 29, because the gear needs to be able to go deep into the gear recess 26 under the condition of mutual engagement with the first tooth belt 25 and the second tooth belt 29, so as to fix the first tooth belt 25 and the second tooth belt 29 from further relative displacement.

[0062] For the convenience of understanding, the whole process of adjusting the length of the glasses legs is explained as follows:

[0063] First, the adjusting knob 24 needs to be pulled axially. The purpose of this step is to pull the gear out of the gear recess 26.

[0064] Second, rotate the adjusting knob 24, and the movable section 21 will move with the rotation of the adjusting knob 24. This step is to adjust the length of the adjustable glasses legs.

[0065] Third, after the length of the adjustable glasses legs is determined, press the adjusting knob 24. This step is to press the gear into the gear recess 26, so as to limit the rotation of the adjusting knob 24 by the gear recess 26.

[0066] The optional embodiment is an inventive point of the embodiment of the present disclosure, which solves the technical problem of poor applicability of AR glasses. The factors leading to poor applicability of AR glasses are as follows: AR glasses are different from ordinary myopia glasses or hyperopia glasses, and have specific requirements for the wearing position of the user to achieve better use experience. The virtual picture presented by the AR glasses needs the eyes of the user to be within the eyebox range to see the complete picture. The glasses legs of the AR glasses cannot adapt to the distance between the eyes and ears of everyone. If the above factors are solved, the effect of improving the applicability of AR glasses can be achieved. In order to achieve this effect, the present disclosure further provides a length-adjustable glasses leg. On the one hand, the user can adjust the length of the glasses leg by rotating the adjusting knob. On the other hand, the gear and the gear recess can also fix the length-adjusted glasses leg. Thus, the applicability of AR glasses is improved.

[0067] Some embodiments of this disclosure provide a glasses hinge that can improve the user experience of AR glasses. Specifically, the reason for the poor user experience of most AR glasses is that when adjusting the nose pad height to allow the eyes to enter the eye box, the overall position of the glasses changes, thereby altering the perspective of the AR image. For example, after raising the nose pad, the image may shift upwards, and the scene seen by the user differs from the originally designed perspective, affecting the immersion and content presentation, resulting in a poor experience when watching videos or playing games. Based on this, some embodiments of this disclosure provide a glasses hinge, which includes a slider, a hinge housing, a hinge inner housing, a connector, and a first elastic member. The hinge housing is connected to the temple. The slider has a slider toothed band, and the hinge inner housing has an inner housing toothed band. The slider toothed band and the inner housing toothed band are configured to mesh with each other. The first elastic member abuts against the slider and the hinge inner housing or the hinge housing, respectively. The slider is embedded within the hinge housing, and the hinge housing and the hinge inner housing are rotatably connected via the connector. When the inner housing toothed band meshes with the slider toothed band, the angle of the hinge housing relative to the XOY plane changes. This is because the slider and the hinge inner housing can change their included angle through the misalignment of the slider toothed band and the inner housing toothed band. Furthermore, the slider being embedded within the hinge housing allows the included angle of the hinge housing with the XOY plane to change, thereby enabling the temple to be adjusted vertically. This improves the user experience of AR glasses.

[0068] Figure 11 This is a schematic diagram of the structure of smart glasses according to some embodiments of this disclosure. Figure 11 It includes slider 1, inner shell of rotating shaft 2, outer shell of rotating shaft 3, and eyeglass body 9.

[0069] In some embodiments, the above-mentioned smart glasses include, for example, Figures 1-7 The corresponding eyeglass hinges and eyeglass body 9. The aforementioned eyeglass body 9 can be AR glasses without temples. There can be two eyeglass hinges, each mounted on one side of the aforementioned eyeglass body 9. This is to ensure that both temples of the AR glasses can be vertically adjusted.

[0070] Optionally, such as Figure 1 and Figure 3 As shown, the aforementioned eyeglass pivot may also include Figure 3 The connecting shaft 14 is shown. The connecting shaft 14 can be a cylindrical structure used to connect the inner housing 2 of the rotating shaft and the eyeglass body 9. For example, it can be a pin, but this is not specifically limited. The side of the eyeglass body 9 can be provided with... Figure 1The first connecting ear 8 is shown. The first connecting ear 8 can be a cylindrical structure located on the side of the eyeglass body 9. The other side of the inner housing 2 of the rotating shaft can be provided with... Figure 1 The second connecting ear 7 is shown. The second connecting ear 7 may include two ear pieces of the same size. The second connecting ear 7 may be two cylindrical structures disposed on the inner housing 2 of the rotating shaft. Both the first connecting ear 8 and the second connecting ear 7 may have a hole in the middle. The diameter of the hole may be the same as the diameter of the connecting shaft 14, so that the connecting shaft 14 can be inserted into the hole. The inner housing 2 of the rotating shaft can be connected to the eyeglass body 9 by simultaneously inserting the connecting shaft 14 into both the first connecting ear 8 and the second connecting ear 7. For example, the two connecting ear pieces of the second connecting ear 7 sandwich the first connecting ear 8 in the middle, and control the axes of the second connecting ear 7 and the first connecting ear 8 to be on the same axis, before inserting the connecting shaft 14. This allows the inner housing 2 of the rotating shaft to rotate around the connecting shaft 14 and the eyeglass body 9. Since the inner housing 2 and the outer housing 3 of the rotating shaft are connected, both the outer housing 3 and the inner housing 2 can rotate simultaneously around the connecting shaft 14. Furthermore, the outer housing 3 can have temples. Therefore, the temples can rotate around the connecting shaft 14 to allow for the opening and closing of the temples relative to the eyeglass body 9.

[0071] Optionally, such as Figure 3 As shown, the aforementioned eyeglass hinge may further include a second elastic element 13. One side of the second elastic element 13 can abut against the inner shell 2 of the hinge, and the other side can abut against the eyeglass body 9. The purpose of this arrangement is to provide a lateral clamping force to the temples when the user wears the eyeglasses, making the eyeglasses fit more securely. The second elastic element 13 can be a compression spring or a torsion spring, and no specific limitation is made here. In order to fix the second elastic element 13 between the inner shell 2 of the hinge and the eyeglass body 9, a fixing structure can be provided on the inner shell 2 of the hinge and the eyeglass body 9. Figure 3 The diagram shows a fixing structure that can be provided when the second elastic element 13 is a compression spring. Specifically, a limiting rod can be provided on the inner shell 2 of the rotating shaft to allow the compression spring to be fitted, and a groove can be provided on the eyeglass body 9 to accommodate the compression spring. By fitting both sides of the compression spring onto the limiting rod and into the groove, the fixing function can be achieved. No specific limitations are made regarding the fixing structure described above.

[0072] Some embodiments of the present disclosure provide a smart glasses which can improve the use experience of AR glasses. Specifically, the reason why the use experience of most AR glasses is not good is that most AR glasses will cause the overall position of the glasses to change when adjusting the height of the nose pad to make the eyes enter the eyebox, thereby changing the viewing angle of the AR imaging picture. It affects the immersion and content presentation effect of watching. Based on this, some embodiments of the present disclosure provide a smart glasses, which comprises Figures 1-7 A corresponding glasses pivot and a glasses body. The glasses pivot is installed on both sides of the glasses body. Because the glasses pivot can make the smart glasses have the function of adjusting the vertical angle of the glasses leg, the viewing angle will not change when adjusting the height of the nose pad to make the eyes enter the eyebox. Therefore, the use experience of AR glasses is improved.

[0073] The above description is only some preferred embodiments of the present disclosure and an explanation of the technical principles applied. Those skilled in the art should understand that the scope of the application involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combinations of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept. For example, the above features are replaced with each other to form a technical solution with similar functions disclosed in the embodiments of the present disclosure (but not limited to).
