[0030] Figure 1 An electrical control schematic diagram of the smart glasses provided by an embodiment of the present invention; Figure 2 An axonometric diagram of the smart glasses provided by an embodiment of the present invention; Figure 3 A front view of the smart glasses provided by an embodiment of the present invention; Figure 4 A partial cross-sectional view of the smart glasses provided by an embodiment of the present invention. Figure 1-Figure 4As shown, the smart glasses provided in this embodiment include: a lens 10 , a frame 20 , a lens driving device 30 , a light sensor 40 and a control chip 50 .

[0031] The lens 10 is filled with dimethyl silicone oil so that the lens 10 can be stretched. The lens 10 is arranged in the frame 20, and can be slidably arranged in the frame 20. The frame 20 has a reserved space for the lens 10 to be stretched; the lens driving device 30 is connected to the lens 10 and is used to stretch the lens 10. The light sensor 40 is electrically connected to the lens driving device 30 and is used to sense the intensity of external light. The control chip 50 is electrically connected to the light sensor 40 and is used to receive the light intensity signal sent by the light sensor 40, and control the lens driving device 30 to perform the action of stretching the lens 10 according to the light intensity signal.

[0032] Specifically, during the manufacturing process of the lens 10, a silicone material may be added. This material is called polydimethylsiloxane (dimethyl silicone oil, also known as polydimethylsiloxane), which is a hydrophobic silicone material and is used in various fields such as medicine, daily chemicals, food, and construction. The latest research has found that the characteristic of this material is that it has a dark area that is opaque under normal circumstances, but it gradually becomes transparent when stretched. In the process of gradually becoming transparent, the transmittance changes continuously, and the transmittance is the highest in a completely transparent state.

[0033] like Figure 4 As shown, the frame 20 has a reserved space A for the lens 10 to be stretched, wherein the reserved space A refers to the area of ​​the lens 10 that does not completely occupy the entire frame 20 when the lens 10 is in the original unstretched state, so that the lens 10 has space to unfold after being stretched. A slide groove for the lens 10 to slide can be provided on the inner side of the frame 20. During the stretching process, the lens 10 slides in the slide groove of the frame 20 and gradually occupies a larger area of ​​the frame 20.

[0034] In life, for example, in the following scenarios, there are more and more cars on the road, and the number of cars driving at night is also increasing. However, due to the dim light at night, the field of vision is affected, and the driver's judgment of the actual distance of objects on the road will have a certain deviation, which is easy to make misjudgments and cause car accidents. The projection distance of the low beam is short, and people, objects or cars far away cannot be found in time, and judgments cannot be made early. There is no time to deal with emergencies, which is easy to cause accidents. Therefore, many car owners will choose to turn on the high beam to increase the irradiation distance and projection range. The high beam light is strong and far away. When meeting, it will instantly blind people in the opposite lane for more than 3 seconds, which will cause panic in the opposite driver, trigger misoperation, and cause unnecessary accidents. If the speed is fast, the probability of danger will be greater. If the driving time is long, this uninterrupted blinding will cause damage to the eyes and make driving more difficult. For the above-mentioned life scenes, giving the driver smart glasses with adjustable light transmittance can solve the above-mentioned technical problems. In this embodiment, the light sensor 40 detects the external light intensity. When the light sensor 40 detects that the external light intensity is weak, in order to ensure the driver's field of vision, the light transmittance of the lens 10 should be as high as possible. At this time, the control chip 50 receives the lower light intensity signal and judges and processes it. The control chip 50 can be set with a predetermined maximum threshold of external light intensity by default for the control chip 50 to judge and control the lens driving device 30 to perform the action of stretching the lens 10. The control chip 50 is also used to control the lens driving device 30 to stop the action after the lens 10 is stretched to the target light transmittance, so that the lens 10 is maintained at the target light transmittance. Since the light transmittance of the lens 10 corresponds to the stretching degree of the lens 10, the lens driving device 30 is also used to maintain the stretching degree of the lens 10 after reaching the target light transmittance. During the stretching process of the lens 10, its light transmittance gradually increases, and the driver can see the front of the field of vision more clearly. When the other vehicle turns on the high beam, the light sensor 40 detects that the external light intensity is strong. In order to avoid damaging the driver's eyes, the transmittance of the lens 10 needs to be reduced. At this time, the control chip 50 receives the higher light intensity signal, judges and processes it, and controls the lens drive device 30 to slowly release the lens 10, so that the stretching degree of the lens 10 is reduced and maintained at the required stretching degree. During the release process, the lens 10 continuously retracts, and its transmittance gradually decreases, which can prevent high-intensity light such as high beams from damaging the driver's eyes and can effectively improve night driving safety.

[0035] In this embodiment, after the lens 10 is stretched to the desired stretching degree, that is, the target transmittance, during use in the state of the transmittance, the lens driving device 30 maintains the stretching degree of the lens 10. When the transmittance needs to be adjusted again, for example, when the transmittance needs to be reduced, the lens driving device 30 can release the lens 10. Since the lens 10 has the property of being retractable and deformable, the driving force applied by the lens driving device 30 is released, and the lens 10 can restore the deformation. During the process of restoring the deformation, the transmittance continues to decrease.

[0036] Furthermore, a power supply circuit 60 may be included, which is electrically connected to the control chip 50 and is used to supply power to the control chip 50. The power supply circuit 60 may use a replaceable battery and a related power supply circuit. The power supply circuit 60 may directly supply power to the control chip 50, and the control chip 50 may indirectly supply power to the light sensor 40 and the lens driving device 30.

[0037] The smart glasses provided by the embodiments of the present invention can be stretched because dimethyl silicone oil is filled in the lenses, and the dimethyl silicone oil has the property of variable transmittance after stretching. The intensity of external light can be sensed in real time by the light sensor, and the collected external light intensity signal is transmitted to the control chip for processing. The control chip controls the lens driving device to stretch the lens according to the external light intensity signal, thereby changing the transmittance of the lens. This can achieve the purpose of automatically adjusting the transmittance of the glasses according to the external light intensity, and can greatly improve the use flexibility of the smart glasses and improve the user experience.

[0038] Specifically, Figure 3 As shown, two lens driving devices 30 may be connected to each lens 10, and the two lens driving devices 30 are respectively connected to the first side 11 and the second side 12 of the lens 10, wherein the first side 11 and the second side 12 are arranged opposite to each other. The lens driving device 30 may be arranged in the frame 20, and a cavity may be arranged in the frame 20 to accommodate the lens driving device 30. The first side 11 and the second side 12 may be the upper and lower sides of the lens 10, or the left and right sides of the lens 10, which is not limited in this embodiment. In the manner of this embodiment, both sides of the lens 10 are stretched, which can make the stretching force of the lens 10 more uniform, and the change of its light transmittance is also more uniform, and the user experience is better.

[0039] As an optional implementation, each lens 10 may be connected to only one lens driving device 30, a first side of the lens 10 is fixed to the frame 20, and a second side of the lens 10 opposite to the first side is connected to the lens driving device 30. In this way, the lens 10 can also be stretched, but the stretching uniformity of the stretched lens 10 is poorer than that of the above-mentioned way.

[0040] The present embodiment further includes a lens holder 70 for holding the lens 10. The lens holder 70 is slidably disposed in the lens frame 20. The lens 10 is connected to the lens driving device 30 via the lens holder 70. Figure 4 As shown, the lens holder 70 may be U-shaped, and the U-shaped lens holder 70 is clamped on the edge of the lens 10. The lens holder 70 may be a plastic part, and is fixedly connected to the lens 10, for example, by gluing. The driving end of the lens driving device 30 is fixedly connected to the lens holder 70, and the lens driving device 30 provides a pulling force to the lens holder 70, and the lens holder 70 drives the lens 10 to stretch.

[0041] Based on the above embodiments, preferably, Figure 4 As shown, the lens driving device 30 may include a motor 31 and a flexible transmission member 32, one end of the flexible transmission member 32 may be wound around the output shaft 311 of the motor 31, and the other end of the flexible transmission member 32 may be connected to the lens clamp 70. Preferably, the lens clamp 70 in this embodiment, the flexible transmission member 32 may be a nylon rope. The extension direction of the output shaft 311 of the motor 31 may be perpendicular to the stretching direction of the lens 10. When the motor 31 rotates, the flexible transmission member 32 fixed on the output shaft 311 of the motor 31 is driven to be wound around the output shaft 311. Compared with the rigid transmission member, the transmission distance can be reduced as much as possible by transmitting power through the flexible transmission member 32, which can save space and effectively reduce the volume of the glasses.

[0042] In addition, the lens holder 70 may be provided with an opening (not shown) in the thickness direction, and the flexible transmission member 32 may be fixed at the opening. Preferably, the opening is provided in the middle of the lens holder 70, thereby ensuring better force uniformity, and the flexible transmission member 32 is directly connected to the opening, which has a simple structure and is easy to assemble.

[0043] As another optional implementation, the lens driving device 30 can also be a linear driver, the output shaft of the linear driver is connected to the lens clamp 70, and the extension direction of the output shaft of the linear driver 30 is consistent with the stretching direction of the lens. In this embodiment, the lens driving device 30 can be a driving device that directly outputs a linear driving force, such as a cylinder or a linear motor. This method allows the lens 10 to be stretched directly, and the intermediate transmission member can be omitted.

[0044] Furthermore, the above-mentioned smart glasses may also include an operation module 80, which is connected to the control chip 50, and is used for the user to input a predetermined maximum threshold of the intensity of external light allowed to pass through the lens 10, so that the control chip 50 controls the lens driving device 30 to operate according to the maximum threshold of the intensity of external light and the light intensity signal. Specifically, Figure 2As shown, the operation module 80 may have two operation buttons "+" and "-". The user may select the operation button to increase or decrease the maximum threshold of the external light intensity, or may directly input the maximum threshold of the external light intensity to be set, which is not limited in this embodiment.

[0045] When the external light intensity detected by the light sensor 40 is higher than the maximum external light intensity threshold set by the operating module 80, the control chip 50 will send instructions to control the lens driving device 30 to work, and reduce the light intensity entering the eye by reducing the transmittance of the lens 10; when the light sensor 40 detects that the external light intensity is lower than the set maximum external light intensity threshold, the control chip 50 can control the lens driving device 30 to work, and gradually increase the transmittance of the lens 10 to the maximum.

Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but rather use differences in components' functions as the criteria for distinction.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
