[0029] With the development and popularity of smart glasses, there are more and more smart glasses in the market. Different people have different pupil distances, but the display area of the smart glasses is fixed. Usually, the display area is designed for standard pupil distance. However, when different people wear glasses, the center of the frame and the position of the eyeball are not the same, which causes the display area not to be directly opposite to the eyeball when people with other pupil distances wear smart glasses, and the visual experience is poor.

[0030] The embodiment of the present application provides a kind of smart glasses, smart glasses can be AR glasses, VR glasses or MR glasses etc., to solve the problem that the pupil distance of existing smart glasses cannot be adjusted, resulting in poor user experience. The following will be combined with the drawings of the present application to illustrate the technical scheme of the present application. Figures 1-5 .

[0031] The smart glasses provided by the embodiment of the present application, as shown in Figure 1 and Figure 4 , comprising first frame 100 second frame 200 and adjusting assembly 300, first frame 100 is provided with first plug-in part 110, first plug-in part 110 is provided with optical axis 120;Second frame 200 is provided with second plug-in part 210, second plug-in part 210 is formed with plug-in groove 211, first plug-in part 110 is inserted into plug-in groove 211;Adjusting assembly 300 includes gear 310 and gear 310 meshing with rack 320, gear 310 is sleeved on optical axis 120, and rack 320 is arranged on first plug-in part 110.

[0032] Optionally, the first frame 100 (for example, corresponding to the left frame) extends the first plug-in part 110, and the first plug-in part 110 is a long strip structure, and a optical axis 120 is coaxially arranged on the first plug-in part 110. The optical axis 120 not only serves as a structural support, but also serves as the rotation axis of the gear 310, ensuring the stability and concentricity of the gear 310 during rotation. The overall shape of the first plug-in part 110 matches the plug-in groove 211 of the second plug-in part 210 to achieve smooth linear sliding. On the upper surface or side surface of the first plug-in part 110, a rack 320 is further arranged. The rack 320 and the first plug-in part 110 can be integrally formed or fixedly connected later, and the tooth shape direction of the rack 320 is consistent with the sliding direction of the plug-in part.

[0033] The second frame 200 (for example, corresponding to the right frame) is provided with the second plug-in part 210, and the second plug-in part 210 is internally provided with the plug-in groove 211, which is designed in size and shape to accommodate the first plug-in part 110 and allow the first plug-in part 110 to freely slide along the groove direction. The two side walls of the plug-in groove 211 play a guiding role, ensuring that the first frame 100 does not deviate or shake during movement, thereby ensuring the accuracy and stability of the adjustment.

[0034] The adjusting assembly 300 comprises a gear 310 and a rack 320. The gear 310 is sleeved on the optical axis 120 of the first inserting part 110 and can rotate freely around the optical axis 120. The outer edge of the gear 310 is processed with gear teeth, which are matched with the rack 320 to form a meshing relationship. The rack 320 is arranged on the first inserting part 110 and is precisely meshed with the gear 310. When the gear 310 rotates, the gear teeth of the gear 310 will push the rack 320 to move in a linear direction. The meshing structure of the adjusting assembly 300 is similar to a worm gear, which has a large transmission ratio and has a certain self-locking property.

[0035] When the user rotates the gear 310, the rotational motion of the gear 310 is converted into the linear motion of the first inserting part 110 through the meshing rack 320. Since the first inserting part 110 is connected with the second inserting part 210 through the inserting slot 211, the first frame 100 will be translated relative to the second frame 200, so as to change the distance between the first frame 100 and the second frame 200, thereby realizing the adjustment of the interpupillary distance of the smart glasses, enabling the center of the display area to be accurately aligned with the center of the user's pupil, and improving the wearing comfort and visual experience of the user.

[0036] Optionally, the first inserting part 110 and the second inserting part 210 can correspond to the position of the bridge of the smart glasses. Without changing the appearance of the smart glasses, a gear 310 and a rack 320 structure are designed at the bridge position, and the distance between the first frame 100 and the second frame 200 can be adjusted by manually adjusting the gear 310.

[0037] In an optional embodiment, in combination with the drawings shown in Figure 2 、 Figure 3 and Figure 4 , the smart glasses further comprise a limiting assembly 400. The limiting assembly 400 is rotationally arranged on the second inserting part 210, and the limiting assembly 400 is adapted to rotate between a first position and a second position. In the first position, the limiting assembly 400 abuts and locks the gear 310, and in the second position, the limiting assembly 400 is separated from the gear 310.

[0038] In this embodiment, when the limiting assembly 400 rotates to the first position, the gear 310 is in a locked state and cannot rotate, and the linear motion of the rack 320 is also prohibited, and the distance between the first frame 100 and the second frame 200 is rigidly locked. When the user needs to adjust the interpupillary distance again, the limiting assembly 400 only needs to be rotated from the first position to the second position, so that the gear 310 is in an unlocked state. The user can manually rotate the gear 310 again to smoothly adjust the distance between the first frame 100 and the second frame 200 to adapt to the new interpupillary distance requirement.

[0039] By setting the limiting assembly 400 to unlock or lock the gear 310, the structural stability and reliability of the adjusting assembly 300 are improved, accidental rotation of the gear 310 is avoided, and user operation experience is optimized.

[0040] In an optional embodiment, as shown in Figure 2 、 Figure 4 and Figure 5 , the limiting assembly 400 includes a mounting seat 410 and a limiting rod 420, the mounting seat 410 is mounted on the second plug-in part 210, one end of the limiting rod 420 is rotationally connected with the mounting seat 410, and the other end is provided with a protruding tooth 421, when the limiting rod 420 is rotated to the first position, the protruding tooth 421 is engaged with and locked with the gear 310.

[0041] Alternatively, the mounting seat 410 can be integrally formed with the second plug-in part 210, or mounted on the second plug-in part 210 by screws, one end of the limiting rod 420 is designed with a shaft hole or a shaft sleeve matched with the rotating shaft hole on the mounting seat 410, through this structure, the limiting rod 420 is pivotally mounted on the mounting seat 410, so that it can freely rotate around the predetermined axis. The other end of the limiting rod 420 is provided with at least one protruding tooth 421. The protruding tooth 421 is not simply a protrusion, but a precisely calculated tooth structure, the tooth profile (including tooth height, tooth thickness, pressure angle and other parameters) is highly matched with the tooth groove shape of the gear 310, so as to realize precise engagement and lock the gear 310, and improve the locking reliability.

[0042] In an optional embodiment, as shown in Figure 1 and Figure 4 , the second plug-in part 210 is provided with an avoiding groove 212, the avoiding groove 212 is communicated with the plug-in groove 211, and the gear 310 at least partially penetrates out of the avoiding groove 212.

[0043] Exemplarily, the avoiding groove 212 is located at the bottom of the second plug-in part 210 and is communicated with the plug-in groove 211, the existence of the avoiding groove 212 provides a physical window for the gear 310 to interact with the outside world. The rim of the gear 310 will penetrate out of or be exposed from this window. The user can directly touch the gear 310 with fingers or with the help of a simple tool, so as to exert a rotating torque.

[0044] It can be understood that the boundary of the avoidance groove 212 is not only a window, but also plays a physical limiting role. When the turbine rotates, the passing part will be limited by the edge of the avoidance groove 212, thereby preventing it from being pulled out and ensuring that the turbine always maintains the correct axial position on the optical axis 120 during rotation and does not come out or jam due to improper operation. By designing the length of the avoidance groove 212, the maximum rotation angle of the turbine can be indirectly limited, thereby setting a safe mechanical adjustment range for the interpupillary distance adjustment to prevent the user from over-adjusting and causing the frame to separate or the internal structure to be damaged.

[0045] In an optional embodiment, the limiting component 400 further comprises a hinge (not shown in the figure) arranged at the connection between the limiting rod 420 and the mounting base 410 to provide a pre-tightening force. The hinge can be a pin-type hinge or a torsional spring hinge, which is used to provide a pre-tightening force to achieve automatic locking and keep the limiting rod 420 in the first position to lock the gear 310.

[0046] In an optional embodiment, as shown in Figure 4 The rack 320 is integrally formed with the first plug-in part 110, which improves the structural strength and rigidity and simplifies the assembly process and reduces the manufacturing cost.

[0047] In an optional embodiment, the smart glasses further comprise: an interpupillary distance detection module for detecting interpupillary distance data of the wearer; a control module electrically connected to the interpupillary distance detection module, configured to receive the interpupillary distance data and generate an adjustment control signal according to a preset algorithm; and a driving module electrically connected to the control module and the adjustment component 300, configured to drive the adjustment component 300 to adjust the distance between the first frame 100 and the second frame 200 based on the adjustment control signal.

[0048] Optionally, the interpupillary distance detection module is arranged in at least one of the first frame 100 and the second frame 200, and the interpupillary distance detection module comprises an infrared distance sensor or a miniature camera.

[0049] For example, a miniature infrared emitter and receiver can be integrated symmetrically on the left and right sides of the nose pad or the inner side of the frame. When the user wears the glasses, the sensor emits an infrared light or laser beam of a specific wavelength to the corneas of the left and right eyes of the user. By calculating the round-trip time or phase difference of the light beam, the distance from the sensor to the eyes can be accurately measured, and then the interpupillary distance of the user can be accurately calculated by combining the fixed length between the sensors.

[0050] One or two high-resolution miniature cameras can also be integrated above or inside the frame. When the user wears the smart glasses, the cameras capture the image or video stream of the user's face. The built-in image processing chip runs advanced computer vision algorithms (such as face key point detection, iris positioning, pupil center recognition, etc.), which can identify and locate the center point coordinates of the user's left and right pupils in real time, and then directly calculate the interpupillary distance value.

[0051] After the user wears the smart glasses, the interpupillary distance of the smart glasses can be automatically adjusted in the above manner, without the need for manual operation, improving the accuracy and reliability of the adjustment and enhancing the user's experience.

[0052] In an optional embodiment, the smart glasses further include a storage module electrically connected to the control module, configured to store interpupillary distance data of at least one user; the control module is configured to call the corresponding interpupillary distance data according to the selected user profile and generate an adjustment control signal.

[0053] In this embodiment, the interpupillary distance data of different users is pre-stored in the storage module. When the same user or another user whose profile has been stored wears the glasses again, the user's profile is selected through some interactive way (such as voice instruction, mobile phone App selection, physical button on the glasses or facial recognition). The control module reads the interpupillary distance data associated with the selected profile from the storage module and compares it with the actual width of the current frame to calculate the distance and direction that needs to be adjusted, generate an accurate adjustment control signal, and finally complete the automatic adjustment of the frame spacing through the driving module, greatly improving the efficiency and experience in a multi-user scenario.

[0054] In an optional embodiment, the smart glasses further include a displacement detection module for detecting the relative adjustment displacement between the first frame 100 and the second frame 200; a display compensation module electrically connected to the displacement detection module and configured to adjust the display parameters of the smart glasses based on the relative adjustment displacement.

[0055] For example, the displacement detection module can include a gyroscope or an accelerometer or other sensors capable of detecting displacement; the display parameters can include at least one of parallax, image distortion correction parameters and binocular image spacing.

[0056] It can be understood that after the interpupillary distance is adjusted, the smart glasses may have problems such as time difference error or image misplacement. The display compensation module compensates and adjusts to eliminate the negative impact of interpupillary distance adjustment on display quality, greatly improve the user's visual comfort, effectively relieve the user's visual fatigue, and improve the display accuracy and immersion of the smart glasses.

[0057] The smart glasses provided by the embodiments of the present application comprise a first frame 100, a second frame 200 and an adjusting assembly 300, the first frame 100 is provided with a first inserting part 110, the first inserting part 110 is provided with an optical axis 120; the second frame 200 is provided with a second inserting part 210, the second inserting part 210 is formed with an inserting slot 211, the first inserting part 110 is inserted into the inserting slot 211; the adjusting assembly 300 comprises a gear 310 and a gear rack 320 engaged with the gear 310, the gear 310 is sleeved on the optical axis 120, and the gear rack 320 is arranged on the first inserting part 110. When a user rotates the gear 310, the rotary motion of the gear 310 is converted into the linear motion of the gear rack 320, the motion of the gear rack 320 drives the first inserting part 110 to slide in the inserting slot of the second inserting part 210, so that the distance between the first frame 100 and the second frame 200 can be adjusted, the pupil distance of the smart glasses is adjusted, the center of the display area is aligned with the pupil of the user, and the wearing comfort and the visual experience of the user are improved.
