DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0039] With reference to Figure 1 , Figure 3 and Figure 4 , an embodiment provided by the utility model: the AR glasses vision correction device based on the liquid crystal variable focus film, including glasses shell 1, the inside fixed connection of glasses shell 1 has mounting frame 3, the inside of mounting frame 3 is provided with two mounting grooves 4, two mounting grooves 4 are all clamped with lens holder 5 in the inside, the inside of two lens holders 5 is all fixedly connected with optical waveguide lens 6, the inside of two optical waveguide lenses 6 is all fixedly connected with liquid crystal variable focus film 7, the inside front side of glasses shell 1 is fixedly connected with display screen 8, the left side of glasses shell 1 is fixedly connected with optical machine module 9, optical machine module 9 and display screen 8 are electrically connected, glasses shell 1 is provided with binding assembly on the back, and glasses shell 1 is provided with nose pad adjusting mechanism 2 on the bottom.

[0040] Specifically, in the AR glasses vision correction device based on the liquid crystal variable focus film, the glasses shell 1 is used to build the installation position of the whole device, and the mounting frame 3 is firmly connected inside the glasses shell 1. Two mounting grooves 4 are arranged in the mounting frame 3, which can accurately fit the lens holder 5, so that the lens holder 5 can be tightly clamped therein, and then the optical waveguide lens 6 can be stably fixed. The optical waveguide lens 6 undertakes the task of light transmission in the device, and the liquid crystal variable focus film 7 fixed inside the optical waveguide lens 6 is the core of realizing the vision correction function. After the vision correction device is started, the optical machine module 9 located on the left side of the glasses shell 1 starts to work. The optical machine module 9 and the display screen 8 fixed on the front side of the inside of the glasses shell 1 are electrically connected to establish a signal transmission channel. The optical machine module 9 generates image light signals, which are quickly transmitted to the display screen 8 along the channel. The display screen 8 converts the received image light signals into visible images for users to watch. The light emitted by the visible images then enters the optical waveguide lens 6. If the user has vision problems and needs to correct vision, an external control device can be used to input an electrical signal to the liquid crystal variable focus film 7. Under the action of the electrical signal, the arrangement state of the liquid crystal molecules in the liquid crystal variable focus film 7 changes. The change of the arrangement state of the liquid crystal molecules directly leads to the corresponding change of the focal length of the film. By accurately controlling the strength of the electrical signal output by the external control device, the focal length of the liquid crystal variable focus film 7 can be accurately adjusted. After such adjustment, the light can smoothly enter the human eye at the right angle and focus state after being transmitted through the optical waveguide lens 6, thereby realizing effective correction of the user's vision and enabling the user to clearly see the images presented by the display screen 8. In the wearing process, the binding assembly arranged on the rear side of the glasses shell 1 can firmly fix the glasses on the user's head, ensuring that the glasses will not shake during use. The nose pad adjusting mechanism 2 at the bottom of the glasses shell 1 can flexibly adjust the position and angle of the nose pad according to the nose shape characteristics of different users and the personalized needs of wearing comfort, ensuring that the whole glasses are stable and comfortable to wear, and effectively ensuring that the focal length is adjusted according to the user's vision condition to correct the vision, and at the same time, the glasses will not interfere with the use effect due to wearing problems.

[0041] Referring to Figure 1 , Figure 2 and Figure 4 , the nose pad adjusting mechanism 2 comprises two fixed sleeves 201, two fixed sleeves 201 are respectively fixedly connected to the left and right sides of the bottom of the glasses shell 1, two adjusting knobs 202 are rotatably connected to the top of the glasses shell 1, two adjusting knobs 202 are fixedly connected with adjusting screws 203 at the bottom, two adjusting screws 203 are externally threaded with threaded sleeves 204, two threaded sleeves 204 are rotatably connected with rotating top sleeves 205 at the bottom, two rotating top sleeves 205 are fixedly connected with angle adjusting balls 206 at the bottom, and two angle adjusting balls 206 are rotatably connected with rubber nose pads 207.

[0042] Specifically, the two fixed sleeves 201 in the nose pad adjustment mechanism 2 are firmly fixed to the left and right sides of the bottom of the eyeglass shell 1, providing a support base for the entire nose pad adjustment mechanism 2. An adjustment knob 202 is rotatably connected to the top of the fixed sleeve 201. When the user needs to adjust the position or angle of the nose pad, a rotational force is applied to the adjustment knob 202. An adjustment screw 203 is fixedly connected to the bottom of the adjustment knob 202. The rotation of the adjustment knob 202 drives the adjustment screw 203 to rotate synchronously. Since the adjustment screw 203 and the threaded sleeve 204 are connected by a thread, the rotation of the adjustment screw 203 causes the threaded sleeve 204 to produce a linear displacement along the screw axis. This threaded transmission method precisely converts the circular motion of the adjustment knob 202 into the linear motion of the threaded sleeve 204. A rotating top sleeve 205 is rotatably connected to the bottom of the threaded sleeve 204. The linear displacement of the threaded sleeve 204 pushes the rotating top sleeve 205... As the top cover 205 moves, the angle adjustment ball 206, which is fixedly connected to the bottom of the rotating top cover 205, moves along with it. Because it is rotatably connected to the rubber nose pad 207, the rubber nose pad 207 can be flexibly adjusted in angle as its position changes. When the user wants to raise the nose pad height, rotating the adjustment knob 202 clockwise rotates the adjustment screw 203, causing the threaded sleeve 204 to move upwards. The top cover 205, angle adjustment ball 206, and rubber nose pad 207 rise accordingly. If the user needs to fine-tune the nose pad angle for a better fit, the angle adjustment ball 206 can rotate within the rubber nose pad 207, achieving flexible multi-angle adjustment. This allows for easy and precise adjustment of the nose pad's position and angle according to individual nose shape and wearing comfort needs, ensuring the stability and comfort of the glasses during vision correction and AR display, and preventing wearing problems from interfering with the usage effect.
