Technical Field

[0001] This invention relates to the field of wearable display device technology, and in particular to a smart glasses. Background Technology

[0002] In the current field of wearable devices, high-brightness light emitted by an optical engine can provide users with clear image displays in bright outdoor conditions, thereby enhancing the user's experience of the real world. However, this method of relying on increasing the brightness of emitted light can cause discomfort to users due to exposure to strong light, affecting the user experience. Summary of the Invention

[0003] The main objective of this invention is to provide a pair of glasses and a wearable display device, which aims to provide smart glasses with a light-blocking function to reduce light flux in strong light environments and improve the user experience.

[0004] To achieve the above objectives, the present invention provides smart glasses comprising:

[0005] A picture frame having an opening for mounting lenses; and

[0006] A light-shielding structure is provided at the frame opening and has both a light-transmitting state and a light-shielding state.

[0007] When the light-transmitting structure is in the light-shielding state, light enters through the frame opening; when the light-shielding structure is in the light-shielding state, it is used to cover part of the frame opening.

[0008] In one embodiment, the light-shielding structure is arranged circumferentially around the frame opening to enclose and form a light-passing opening for light to pass through.

[0009] In one embodiment, the aperture of the light-passing port is adjustable;

[0010] When the light-blocking structure is in the light-transmitting state, the light-transmitting area of ​​the light-passing opening is not less than the light-transmitting area of ​​the frame opening; when the light-blocking structure is in the light-blocking state, the light-transmitting area of ​​the light-passing opening is less than the light-transmitting area of ​​the frame opening.

[0011] In one embodiment, the light-shielding structure is configured to be made of an opaque material, and at least a portion of the light-shielding structure is movable to move toward or away from the center of the frame opening to increase or decrease the aperture of the light-passing opening.

[0012] In one embodiment, the light-shielding structure includes a plurality of light-shielding members, which are connected in sequence and arranged around the circumference of the frame opening to enclose and form the light-passing opening;

[0013] The smart glasses also include a driving structure, which is connected to one of the light-blocking components to drive the plurality of light-blocking components to move synchronously toward or away from the center of the frame opening.

[0014] In one embodiment, the light-shielding structure is configured to be made of an opaque material, and the light-shielding structure is designed to be stretchable and deformable to increase or decrease the aperture of the light-passing opening.

[0015] In one embodiment, the inner wall of the frame opening is provided with a mounting groove, which is arranged around the circumference of the frame opening. When the light-shielding structure is in the light-transmitting state, it is housed in the mounting groove.

[0016] And / or, when the light-shielding structure is in the light-shielding state, the maximum distance between the inner wall of the light-passing opening and the inner wall of the frame opening is D, which satisfies 15mm≤D≤20mm.

[0017] In one embodiment, the smart glasses further include:

[0018] A photosensitive module is used to detect the brightness information of ambient light; and

[0019] A control module is electrically connected to both the photosensitive structure and the light-shielding structure. The control module is used to control the light-shielding structure to switch between the light-shielding state and the light-transmitting state based on the brightness information of the ambient light.

[0020] In one embodiment, the frame includes two frame openings, and the photosensitive module is disposed on the outer wall of the frame and located between the two frame openings;

[0021] And / or, the photosensitive module is disposed on the outer wall of the frame and located on the top side of the frame;

[0022] And / or, the smart glasses further include temples, with the photosensitive module disposed on the outer wall of the temples.

[0023] In one embodiment, the smart glasses further include temples mounted on one side of the frame, and the light-blocking structure is located on the side of the lens opposite to the temples.

[0024] The technical solution of this invention provides a light-blocking structure at the frame opening of eyeglasses, allowing the structure to have both a light-transmitting and a light-blocking state. When the ambient light is not strong, the light-blocking structure can be in the light-transmitting state, allowing light to pass through the frame opening normally. When the ambient light is strong, the light-blocking structure can be in the light-blocking state, covering at least part of the frame opening. This reduces the light-transmitting area of ​​the eyeglasses, thereby reducing the amount of light received by the human eye and preventing discomfort caused by strong light irradiating the eyes, thus improving the user experience.

[0037] In the current field of wearable devices, high-brightness light emitted by an optical engine can provide users with clear image displays in bright outdoor conditions, thereby enhancing the user's experience of the real world. However, this method of relying on increasing the brightness of emitted light can cause discomfort to users due to exposure to strong light, affecting the user experience.

[0038] This invention proposes a smart glasses 100, which can be an AR glasses or other wearable display device with display function.

[0039] Please see Figures 1 to 5 In an embodiment of the present invention, the smart glasses 100 includes a frame 10 and a light-blocking structure 20. The frame 10 has a frame opening 11 for mounting lenses. The light-blocking structure 20 is disposed at the frame opening 11 and has a light-transmitting state and a light-blocking state. When the light-transmitting state is reached, light enters through the frame opening 11. When the light-blocking structure 20 is in the light-blocking state, it covers part of the frame opening 11.

[0040] In one embodiment, the light-shielding structure 20 can be configured as an opaque material and is movably disposed relative to the frame opening 11. This allows the light-shielding structure 20 to be configured to either partially cover the frame opening 11 or allow light to pass through the frame opening 11 by changing its relative position. When the light-shielding structure 20 partially covers the frame opening 11, it can block some light from entering the frame opening 11. Thus, by adjusting the relative position of the light-shielding structure 20 and the frame opening 11, the amount of light entering the human eye can be controlled.

[0041] In another embodiment, the light-shielding structure 20 can also be fixedly installed inside the frame opening 11 and has an adjustable light transmittance, allowing it to have both a light-shielding state with zero light transmittance and a light-transmitting state with higher light transmittance. When the light transmittance of the light-shielding structure 20 is zero, light can pass through the light-shielding structure 20 through the frame opening 11 and be received by the human eye; when the light transmittance of the light-shielding structure 20 is higher, the light-shielding structure 20 can cover the frame opening 11 to prevent some light from entering the frame opening 11. In this way, the amount of light entering the human eye can be controlled by adjusting the light transmittance of the light-shielding structure 20.

[0042] The technical solution of the present invention provides a light-blocking structure 20 at the frame opening 11 of the eyeglasses frame 10, and the light-blocking structure 20 has a light-transmitting state and a light-blocking state. When the ambient light is not strong, the light-blocking structure 20 can be in the light-transmitting state, at which time the frame opening 11 can transmit light normally; when the ambient light is strong, the light-blocking structure 20 can be in the light-blocking state, at which time the light-blocking structure 20 can cover at least part of the frame opening 11, thereby reducing the light-transmitting area of ​​the eyeglasses and reducing the light flux received by the human eye. This can prevent strong light from shining on the human eye and causing discomfort, thus improving the user experience.

[0043] In an embodiment of the present invention, the light-shielding structure 20 is arranged circumferentially around the frame opening 11 to enclose and form a light-passing opening 22 for light to pass through. Thus, regardless of whether the light-shielding structure 20 is in a light-shielding state or a light-passing state, the user can receive external light through the light-passing opening 22 enclosed by the light-shielding structure 20; that is, the adjustment of the state of the light-shielding structure 20 does not affect the user's viewing of the external environment.

[0044] Please see Figures 1 to 3 In an embodiment of the present invention, the aperture of the light-passing port 22 is adjustable; when the light-shielding structure 20 is in the light-transmitting state, the light-transmitting area of ​​the light-passing port 22 is not less than the light-transmitting area of ​​the frame opening 11; when the light-shielding structure 20 is in the light-shielding state, the light-transmitting area of ​​the light-passing port 22 is less than the light-transmitting area of ​​the frame opening 11.

[0045] With this configuration, since the light-transmitting area of ​​the light-passing opening 22 is not less than the light-transmitting area of ​​the frame opening 11 when the light-blocking structure 20 is in the light-transmitting state, the entire area of ​​the frame opening 11 can be illuminated by light, thereby enabling the smart glasses 100 to have a better field of vision for the external environment in non-strong light environments.

[0046] Furthermore, when the light-blocking structure 20 is in the light-blocking state, the light-transmitting area of ​​the light-passing opening 22 is smaller than the light-transmitting area of ​​the frame opening 11, and the light-passing opening 22 is located at the center of the frame opening 11. Therefore, when the light-blocking structure 20 is in the light-blocking state, basically only light rays incident on the frame opening 11 in the direction parallel to the normal direction can be received by the human eye, while external light rays incident at an angle will be blocked by the light-blocking structure 20. In this way, the light-blocking structure 20 can play a good role in blocking strong light in the external environment. For example, the light-blocking structure 20 can effectively block sunlight from high altitudes, thus effectively preventing strong external light from interfering with the human eye.

[0047] In an embodiment of the present invention, the light-shielding structure 20 is configured to be made of an opaque material, and at least a portion of the light-shielding structure 20 is movably configured to move toward or away from the center of the frame opening 11 to increase or decrease the aperture of the light-passing opening 22.

[0048] In this embodiment, the light-shielding structure 20 is made of an opaque material, and it can be arranged around the circumference of the frame opening 11, extending or retracting towards the center of the frame opening 11. When the light-shielding structure 20 extends towards the center of the frame opening 11, the light-shielding area of ​​the light-shielding structure 20 increases, the aperture of the light-passing opening 22 decreases, and the luminous flux of external light entering the human eye decreases accordingly. When the light-shielding structure 20 retracts away from the center of the frame opening 11, the light-shielding area of ​​the light-shielding structure 20 decreases, the aperture of the light-passing opening 22 increases, and the luminous flux of external light entering the human eye increases accordingly.

[0049] Of course, the technical solution of the present invention is not limited to this. In some embodiments, the light-shielding structure 20 may also have adjustable light transmittance, and the light-shielding structure 20 has multiple annular adjustment areas, which are arranged sequentially from the center of the frame opening 11 to the edge of the frame opening 11. The light-shielding structure 20 can increase or decrease its light-shielding area by independently adjusting the light transmittance of multiple annular adjustment areas, thereby achieving adjustment of the aperture size of the light-passing opening 22. Specific implementation methods can be set according to actual needs and are not limited here.

[0050] Please see Figure 4 In an embodiment of the present invention, the light-shielding structure 20 includes a plurality of light-shielding members 21, which are connected in sequence and arranged around the circumference of the frame opening 11 to form the light-passing opening 22; the smart glasses 100 also includes a driving structure, which is connected to one of the light-shielding members 21 to drive the plurality of light-shielding members 21 to move synchronously toward or away from the center of the frame opening 11.

[0051] Specifically, the light-shielding sheet has an opaque, thin sheet structure. Several light-shielding elements 21 can be stacked sequentially around the circumference of the frame opening 11, and these elements are interconnected by movable hinges. Thus, the light-shielding elements 21 can move synchronously toward or away from the center of the frame opening 11 to increase or decrease the aperture of the light-passing opening 22. A drive structure can be disposed on one side of the light-shielding structure 20, and its output end can be connected to one of the light-shielding elements 21. This output end can be retractably positioned toward or away from the frame opening 11, so that when it extends toward the frame opening 11, it abuts against one of the light-shielding elements 21 as it moves toward the center of the frame opening 11, or when it retracts away from the frame opening 11, it drives the light-shielding element 21 away from the center of the frame opening 11.

[0052] In one feasible implementation, the driving structure includes a driving member, a linkage mechanism, and a slider. The driving member may, but is not limited to, be a stepper motor. The slider is used to connect one of the light-shielding members 21 of the light-shielding structure 20. The driving member can drive the slider to move toward or away from the frame opening 11 through the linkage mechanism, thereby driving several light-shielding members 21 to move synchronously toward or away from the center of the frame opening 11 through the slider.

[0053] Furthermore, in some embodiments, the frame 10 includes two frame openings 11 arranged side by side, and each frame opening 11 is provided with a light-shielding structure 20. In this case, the driving structure can be disposed between the two frame openings 11 and drivenly connected to the two light-shielding structures 20 respectively, so that the two light-shielding structures 20 can synchronously adjust their light-shielding areas under the drive of the same driving structure, thereby realizing the synchronous adjustment of the aperture of the light-passing port 22 within the two frame openings 11. Compared with the technical solution of setting two driving structures to drive the two light-shielding structures 20 respectively, this arrangement can reduce the number of driving structures, thereby helping to reduce the volume occupied by the smart glasses 100.

[0054] In an embodiment of the present invention, the light-shielding structure 20 is configured to be made of an opaque material, and the light-shielding structure 20 is designed to be stretchable and deformable to increase or decrease the aperture of the light-passing port 22.

[0055] The light-shielding structure 20 is a shrinkable and stretchable film. Thus, stretching the film increases the light-shielding area of ​​the light-shielding structure 20, while shrinking the film decreases the light-shielding area. In some embodiments, the light-shielding structure 20 may be specifically configured as a polymer film, the material of which may be, but is not limited to, polyamide, etc., and is not limited thereto.

[0056] Please see Figures 1 to 3In an embodiment of the present invention, the inner wall of the frame opening 11 is provided with a mounting groove 111, which is arranged circumferentially around the frame opening 11. When the light-shielding structure 20 is in the light-transmitting state, it is received within the mounting groove 111. By providing the mounting groove 111, on the one hand, the mounting groove 111 can improve the structural stability of the light-shielding structure 20 by positioning it; on the other hand, the mounting groove 111 can provide a receiving space for the light-shielding structure 20, so that the light-shielding structure 20 can be completely received within the mounting groove 111 when in the light-transmitting state, allowing light to enter the entire area of ​​the frame opening 11. This enables the smart glasses 100 to have a better field of vision for the external environment in non-strong light environments.

[0057] In an embodiment of the present invention, when the light-shielding structure 20 is in the light-shielding state, the maximum distance between the inner wall of the light-passing opening 22 and the inner wall of the frame opening 11 is D, which satisfies 15mm≤D≤20mm.

[0058] When the light-blocking structure 20 is in the light-blocking state, it can block part of the frame opening 11. At this time, the inner wall of the light-passing opening 22 and the inner wall of the frame opening 11 are spaced apart. When the distance between the inner wall of the light-passing opening 22 and the inner wall of the frame opening 11 is too large, the light-blocking area of ​​the light-blocking structure 20 will be too large, affecting the user's visible field of view of the external environment. When the distance between the inner wall of the light-passing opening 22 and the inner wall of the frame opening 11 is too small, the light-blocking area of ​​the light-blocking structure 20 will be too small and will not have a good light-blocking effect. Therefore, the maximum distance D between the inner wall of the light-passing opening 22 and the inner wall of the frame opening 11 can be limited to 15mm to 20mm, specifically 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, and any value within 15mm to 20mm, etc., which are not limited here.

[0059] In an embodiment of the present invention, the smart glasses 100 further includes a photosensitive module 30 and a control module. The photosensitive module 30 is used to detect the brightness information of ambient light. The control module is electrically connected to the photosensitive structure and the light-blocking structure 20 respectively. The control module is used to control the light-blocking structure 20 to switch between the light-blocking state and the light-transmitting state according to the brightness information of the ambient light.

[0060] The photosensitive module 30 can sense the ambient light brightness information of the surrounding environment of the smart glasses 100 and convert it into an electrical signal. The control module can dynamically adjust the working state of the light-blocking structure 20 based on the sensing results of the photosensitive module 30 of the ambient light brightness of the surrounding environment of the smart glasses 100, thereby improving the ease of use and practicality of the smart glasses 100.

[0061] Of course, the technical solution of the present invention is not limited to this. In some embodiments, the control module can also adjust the working state of the light-shielding structure 20 based on user input commands. Specific implementation methods can be set according to actual needs.

[0062] Specifically, in one embodiment of the present invention, the frame 10 includes two frame openings 11, and the photosensitive module 30 is disposed on the outer wall of the frame 10 and located between the two frame openings 11. Alternatively, in another embodiment of the present invention, the photosensitive module 30 is disposed on the outer wall of the frame 10 and located on the top side of the frame 10. Or, in yet another embodiment of the present invention, the smart glasses 100 further includes temples, and the photosensitive module 30 is disposed on the outer wall of the temples. It should be noted that the aforementioned installation methods of the photosensitive module 30 all allow the photosensitive module 30 to be exposed on the outer wall of the smart glasses 100, so that the photosensitive module 30 can directly collect the ambient light brightness of the environment in which the smart glasses 100 is located. By setting the photosensitive module 30 in any of the aforementioned installation positions, the real-time detection function of the ambient light of the smart glasses 100 can be realized, so that the control module can adjust the working state of the light-shielding structure 20 based on the ambient light brightness information. The photosensitive module 30 can be, but is not limited to, an ambient light detector.

[0063] Furthermore, multiple photosensitive modules 30 can be provided. For example, photosensitive modules 30 can be installed in two or more of the aforementioned installation positions, which helps to improve the accuracy of the smart glasses 100 in detecting ambient light brightness.

[0064] In an embodiment of the present invention, the smart glasses 100 further includes temples, which are mounted on one side of the frame 10, and the light-blocking structure 20 is disposed on the side of the lens away from the temples.

[0065] In this embodiment, the smart glasses 100 can be waveguide-type enhanced display glasses. A waveguide lens is installed at the frame opening 11 of the frame 10. The light-emitting module of the smart glasses 100 can emit an imaging beam towards the waveguide lens to transmit the imaging beam to the human eye, and direct the imaging beam towards the human eye so that the human eye can receive the relevant display information from the smart glasses 100. Furthermore, by placing the light-shielding structure 20 on the side of the lens away from the temple, it can be prevented from blocking the transmission path of the imaging beam when the waveguide lens emits the imaging beam towards the human eye, thus avoiding any impact on the display effect of the smart glasses 100.

[0066] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
