[0035] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0036] The present application embodiment provides a wearable device 100, see Figures 1 to 10 As shown, the wearable device 100 includes: a frame 10, an optical structure 20 and a connecting structure 30, the frame 10 is provided with temples 11; the connecting structure 30 includes: a first part 31 and a second part 32, the first part 31 is connected to the frame 10, the second part 32 is connected to the optical structure 20, and the second part 32 is movably connected to the first part 31 to adjust the height of the optical structure 20 relative to the frame 10 after relative movement.

[0037] Specifically, two temples 11 are provided on the frame 10, and the two temples 11 can be worn on the left and right ears of the user respectively.

[0038] The optical structural component 20 can be a myopia lens, a hyperopia lens, a reading lens, an AR structural component, or a VR structural component; when the optical structural component 20 is a myopia lens, the wearable device 100 is a myopia pair of glasses; when the optical structural component 20 is a hyperopia lens, the wearable device 100 is a hyperopia pair of glasses; when the optical structural component 20 is a reading lens, the wearable device 100 is a reading pair of glasses; when the optical structural component 20 is an AR structural component, the wearable device 100 is an AR pair of glasses; when the optical structural component 20 is a VR structural component, the wearable device 100 is a VR pair of glasses.

[0039] The connecting structure 30 includes: a first part 31 and a second part 32, the first part 31 is connected to the frame 10, the second part 32 is connected to the optical structure 20, and the second part 32 is movably connected to the first part 31 to adjust the height of the optical structure 20 relative to the frame 10 after relative movement. That is to say, the first part 31 of the connecting structure 30 is connected to the frame 10, the second part 32 of the connecting structure 30 is connected to the optical structure 20, and the first part 31 and the second part 32 of the connecting structure 30 can move relatively to allow the optical structure 20 to change in height relative to the frame 10. In this way, it can adapt to the height difference between the eyes and ears of different users. At the same time, since the optical structure 20 changes in height relative to the frame 10, the center of the optical structure 20 after the position change is directly opposite to the user's eyes without an angle, thereby ensuring the viewing effect.

[0040] In some embodiments, see Figures 1 to 10 As shown, the first part 31 includes: a first connecting member 311 and a rotating member 312, the first connecting member 311 is connected to the frame 10, the rotating member 312 is rotatably connected to the first connecting member 311, and the rotating member 312 has a first meshing portion 313 and a knob 314; the second part 32 includes: a second connecting member 321 and a second meshing portion 322, the second connecting member 321 is connected to the optical structure 20, the second meshing portion 322 is arranged on the second connecting member 321, and meshes with the first meshing portion 313; wherein, when the knob 314 is subjected to a rotational force, the first meshing portion 313 and the second meshing portion 322 move relative to each other, so that the second part 32 is displaced in the height direction relative to the first part 31.

[0041] Specifically, the first connecting member 311 can be in the shape of a sheet, a rod, or a shape that matches the surface of the frame 10 connected to the first part 31; the first connecting member 311 and the frame 10 bracket can be fixedly connected by means of integral molding, welding, or by means of detachable connection such as screws or snap-fitting. The rotating member 312 is rotatably connected to the first connecting member 311 and can rotate relative to the first connecting member 311, so that a rotational force can be applied to the knob 314 in the rotating member 312 to rotate the first meshing portion 313 of the rotating member 312 relative to the first connecting member 311. Here, the knob 314 can be made of a plastic material injection-molded from common materials such as PC or PC+ABS to reduce the weight of the wearable device 100; the first meshing portion 313 can be made of self-lubricating materials such as POM to ensure that the first meshing portion 313 has reliable lubricity.

[0042] The second connecting member 321 can be in the form of a sheet, a rod, or a shape that matches the surface of the optical structure 20 connected to the second portion 32; the second connecting member 321 is connected to the optical structure 20, so that the second connecting member 321 has strict assembly accuracy and stability. For this purpose, the second connecting member 321 can be made of lightweight metals such as aluminum alloy and titanium alloy; the second connecting member 321 and the optical structure 20 can be fixedly connected by means of integral molding, welding, etc., or can be detachably connected by means of screws, clamping, etc., for example: see Figure 4 As shown, the second connecting member 321 and the optical structural member 20 are connected by screws 201. The second meshing portion 322 disposed on the second connecting member 321 meshes with the first meshing portion 313 on the first connecting member 311, so that when the first meshing portion 313 rotates, the second meshing portion 322 is displaced relative to the first meshing portion 313, so that the optical structural member 20 is displaced relative to the frame 10. At the same time, since the first portion 31 and the second portion 32 are connected by meshing to move relative to each other, the optical structural member 20 is always restricted by the cooperation of the first meshing portion 313 and the second meshing portion 322 during the displacement relative to the frame 10, so that the relative displacement process is smoother.

[0043] In one example, the first connecting member 311 is detachably connected to the frame 10, and the second connecting member 321 is detachably connected to the optical structure 20, so that the connecting structure 30 can be connected between different frames 10 and optical structures 20. For example, the optical structure 20 can be detached from the second connecting member 321 to replace the optical structure 20 with different functions, so that the user can conveniently switch between glasses with different functions.

[0044] In some embodiments, see Figures 3 to 10 As shown, the outer contour of the first meshing portion 313 and the outer contour of the knob 314 both meet the circular condition, the first meshing portion 313 is located on one side of the knob 314 and is coaxially arranged with the knob 314, and the first meshing portion 313 and the knob 314 cooperate to form a convex structure. In this way, the first meshing portion 313 and the knob 314 can be integrally formed and arranged closely to each other, so that the first meshing portion 313 and the knob 314 can have a high structural strength and occupy a small and concentrated space.

[0045] In some embodiments, see Figures 3 to 10As shown, the connection structure 30 may further include: a speed change structure 33, the speed change structure 33 meshes with the first meshing portion 313 and the second meshing portion 322 respectively, and the rotation speed of the speed change structure 33 is different from the rotation speed of the first meshing portion 313. The speed change structure 33 may be a single gear or a plurality of gears meshing with each other, and the rotation speed of the speed change gear is different from the rotation speed of the first meshing portion 313, so as to adjust the rotation speed of the second meshing portion 322, thereby adjusting the speed at which the optical structure 20 is displaced relative to the frame 10.

[0046] In one example, the speed shifting structure 33 is a single gear, and the tooth size of the single gear is larger than the tooth size of the first meshing portion 313, so that after the speed shifting structure 33 transmits the rotational force of the first meshing portion 313 to the second meshing portion 322, the rotation speed of the second meshing portion 322 is lower than the rotation speed of the first meshing portion 313, thereby slowing down the displacement process of the optical structure 20 relative to the frame 10. In this way, the user can more accurately move the optical structure 20 to the required height.

[0047] For another example, see Figures 6 to 10 As shown, the speed change structure 33 is two gears meshing with each other, namely the first gear 331 and the second gear 332, so that after the speed change structure 33 transmits the rotational force of the first meshing part 313 to the second meshing part 322, the rotation speed of the second meshing part 322 is less than the rotation speed of the first meshing part 313, thereby slowing down the displacement process of the optical structure 20 relative to the frame 10. In this way, the user can move the optical structure 20 to the required height more accurately.

[0048] In some embodiments, see Figures 3 to 10As shown, the first connecting member 311 protrudes with a first connecting portion 315 and a second connecting portion 316 opposite to each other; the first part 31 also includes: a first rotating shaft 317 and a second rotating shaft 318, the first rotating shaft 317 passes through the rotating member 312 and is rotationally connected to the first connecting portion 315 and the second connecting portion 316 respectively, and the second rotating shaft 318 passes through the speed change structure 33 and is rotationally connected to the first connecting portion 315 and the second connecting portion 316 respectively. That is to say, the rotating member 312 is connected to the first rotating shaft 317, and the first rotating shaft 317 is rotationally connected to the first connecting part 315 and the second connecting part 316 of the first connecting member 311, so that the rotating member 312 can rotate relative to the first connecting member 311 through the first rotating shaft 317; at the same time, the speed change structure 33 is connected to the second rotating shaft 318, and the second rotating shaft 318 is rotationally connected to the first connecting part 315 and the second connecting part 316 respectively, so that the speed change structure 33 rotates with the rotation of the first meshing part 313, and the second rotating shaft 318 rotates with the speed change structure 33 relative to the first connecting part 315 and the second connecting part 316, so as to be guided by the first connecting part 315 and the second connecting part 316, so that the rotation process of the speed change structure 33 is smoother. In addition, since the first rotating shaft 317 and the second rotating shaft 318 are both connected to the first connecting portion 315 and the second connecting portion 316 of the first connecting member 311, the structural setting of the wearable device 100 can be reduced, thereby simplifying the structure of the wearable device 100 and reducing the manufacturing cost of the wearable device 100.

[0049] In some embodiments, see Figure 6 , Figure 8 and Fig. 9As shown, the first connection part 315 and the second connection part 316 are respectively provided with a first through hole and a second through hole for rotationally connecting to the first rotating shaft 317; the first connection part 315 and the second connection part 316 are respectively provided with a third through hole and a fourth through hole for rotationally connecting to the second rotating shaft 318; the first part 31 also includes: a first fixing plate 319 and a second fixing plate 320, the first fixing plate 319 and the second fixing plate 320 are respectively connected to the two sides of the first connection part 315 and the second connection part 316 opposite to each other, and the first fixing plate 319 blocks the first through hole and the third through hole, and the second fixing plate 320 blocks the second through hole and the fourth through hole. That is, the two ends of the first rotating shaft 317 are respectively penetrated by the first through hole and the second through hole respectively provided on the first connecting portion 315 and the second connecting portion 316 and can rotate relative to the first through hole and the second through hole, and the two ends of the second rotating shaft 318 are respectively penetrated by the third through hole and the fourth through hole respectively provided on the first connecting portion 315 and the second connecting portion 316 and can rotate relative to the third through hole and the fourth through hole, and the first fixing plate 319 and the second fixing plate 320 are respectively connected to the two sides of the first connecting portion 315 and the second connecting portion 316 opposite to each other so as to block the first connecting portion 315 and the second connecting portion 316 from being mutually opposed. The first through hole, the second through hole, the third through hole and the fourth through hole on both sides of the back are opened, so that the first rotating shaft 317 can rotate between the first fixing plate 319 and the second fixing plate 320 without being displaced in the direction of the connection between the first connecting part 315 and the second connecting part 316, and the second rotating shaft 318 can rotate between the first fixing plate 319 and the second fixing plate 320 without being displaced in the direction of the connection between the first connecting part 315 and the second connecting part 316. In this way, the first engaging part 313 and the shifting structure 33 can rotate in the original position to ensure that the optical structure 20 is displaced relative to the frame 10 according to a preset trajectory.

[0050] Here, the first fixing piece 319 can be fixed to the first connecting portion 315 by screws, or can be fixed to the first connecting portion 315 by screws. Fig. 9 The upper and lower ends are bent to be clamped on the side of the first connecting portion 315 facing the second connecting portion 316, and other fixing methods can also be used; the second fixing plate 320 can be fixed to the second connecting portion 316 by screws, or it can be fixed by Fig. 9 The upper and lower ends are bent to be snap-fitted to a side of the second connection portion 316 facing the first connection portion 315 , and other fixing methods are also possible.

[0051] In some embodiments, see Figure 6 , Figure 8 and Fig.10As shown, the first rotating shaft 317 is provided with a first elastic member 3171 on a circle of side walls corresponding to the first through hole; the first rotating shaft 317 is provided with a second elastic member 3172 on a circle of side walls corresponding to the second through hole. In this way, after the first rotating shaft 317 rotates relative to the first connecting portion 315 and the second connecting portion 316, it is subjected to the friction force of the first elastic member 3171 and the second elastic member 3172 to maintain the position after the rotation. Here, the first elastic member 3171 / the second elastic member 3172 can be a silicone structural member, a rubber structural member, or other elastic structural members.

[0052] In some embodiments, see Figures 3 to 6 As shown, the second connecting member 321 protrudes in a direction away from the first connecting member 311 corresponding to the first connecting member 315, the second connecting member 316 and the portion between the first connecting member 315 and the second connecting member 316 to form a receiving space 323, and the first connecting member 315 and the second connecting member 316 are received in the receiving space 323; the second meshing portion 322 is arranged on a surface opposite to the portion between the first connecting member 315 and the second connecting member 316 in the receiving space 323, and the second meshing portion 322 is a rack. In other words, the second connecting member 321 protrudes in a direction away from the first connecting member 311 to form a receiving space 323, and the first connecting member 315, the second connecting member 316 and the portion between the first connecting member 315 and the second connecting member 316 on the first connecting member 311 are located in the receiving space 323, so that a mutually interlocking structure is formed between the first connecting member 311 and the second connecting member 321, thereby making the volume of the wearable device 100 smaller.

[0053] In some embodiments, see Figures 3 to 6As shown, the connection structure 30 may also include: a stop structure 34, the stop structure 34 includes: a first stop portion 341 and a second stop portion 342 are both arranged on the first connection member 311, the first stop portion 341 and the second stop portion 342 correspond to the two ends of the displacement direction of the second connection member 321, and the distance between the first stop portion 341 and the second stop portion 342 along the displacement direction of the second connection member 321 is greater than the size of the second connection member 321 in its displacement direction. That is, the first stop portion 341 and the second stop portion 342 are respectively located above and below the second connecting member 321, and when one of them abuts against the second connecting member 321, the other does not abut against the second connecting member 321; thus, when the second connecting member 321 is raised relative to the first connecting member 311, the second connecting member 321 abuts against one of the first stop portion 341 and the second stop portion 342; and then, when the second connecting member 321 is lowered relative to the first connecting member 311, the second connecting member 321 abuts against the other of the first stop portion 341 and the second stop portion 342. Thus, the first stop portion 341 and the second stop portion 342 limit the displacement of the second connecting member 321.

[0054] In some embodiments, see Figures 3 to 6 As shown, the connection structure 30 may also include: a guide structure 35, which is arranged on the first connection member 311, and the extension direction of the guide structure 35 is consistent with the displacement direction of the second connection member 321; wherein the second connection member 321 is connected to the guide structure 35, and is displaced along the extension direction of the guide structure 35. Here, the guide structure 35 may be a bar groove type track, whose extension direction is consistent with the displacement direction of the second connection member 321, and a slider is arranged on the second connection member 321, and the slider is located in the bar groove type track and can slide along the bar groove type track; the guide structure 35 may also be a bar tooth structure, whose extension direction is consistent with the displacement direction of the second connection member 321, and the second connection member 321 is provided with meshing teeth that match the bar tooth structure, the meshing teeth are meshed with the bar tooth structure and can rotate along the bar tooth structure to move; the guide structure 35 may also be as follows Figures 3 to 6 The hooking structure shown in the figure has a hooking groove which is consistent with the displacement direction of the second connecting member 321, and the second connecting member 321 is hooked with the hooking structure and is at least partially located in the hooking groove so as to be able to move along the hooking groove.

[0056] The frame 10 is provided with two opposite temples 11 for being worn on the left and right ears respectively.
