Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the following embodiments and the accompanying drawings.
As shown in fig. 1 and 2, the smart glasses provided by the embodiment of the invention comprise a frame 1, and a lens 2 is mounted on the frame 1. As shown in fig. 3, the lens 2 includes electrochromic glass 6 and photochromic glass 7. The electrochromic glass 6 is in a fully transparent state when an electric field is not applied, the photochromic glass 7 is in a fully transparent state when the photochromic glass is not illuminated, and the photochromic glass 7 and the electrochromic glass 6 are overlapped and bonded with each other. The frame 1 is also provided with a light sensor 3 and a controller 13.
The light sensor 3 is used for detecting the ambient light intensity, the controller 13 is connected with the light sensor 3 and the electrochromic glass 6, and the controller 13 is used for changing the transmittance of the electrochromic glass 6 according to the ambient light intensity. Photochromic glass 7 can self-adaptation illumination intensity adjust the transmittance, and controller 13 can be according to the ambient light intensity intelligent regulation electrochromic glass 6's transmittance that light sensor 3 detected, through the dual regulation of electrochromic glass 6 and photochromic glass 7 to 2 transmittances of lens, can provide comfortable illumination intensity for glasses to the prevention eyes are near-sighted.
Specifically, when the transmittance of the electrochromic glass 6 is controlled, the controller 13 applies the electric field to the electrochromic glass 6 when the ambient light intensity is higher than the preset threshold value, so as to reduce the transmittance of the electrochromic glass 6, and when the ambient light intensity is not higher than the threshold value, the application of the electric field to the electrochromic glass 6 is stopped, so as to restore the original transmittance of the electrochromic glass 6.
The mirror holder 1 is further provided with an LED indicator light 8, the LED indicator light 8 is connected with a controller 13, and the controller 13 is used for driving the LED indicator light 8 to send out a light alarm signal when the ambient light intensity is not in the preset range continuously and reaches the first time length. This preset scope can make eyes be in the most comfortable illumination intensity scope, and environment illumination intensity neither too strong nor too weak this moment promptly, if environment illumination intensity is below this preset scope's minimum, explains that environment illumination intensity is too weak, if environment illumination intensity is more than this preset scope's maximum value, explains that environment illumination intensity is too strong. When the ambient light intensity is continuously too weak or too strong to reach the preset first time period, the controller 13 sends out a corresponding prompt through the LED indicator 8. The LED indicator lamp 8 is composed of a plurality of single color LED lamps, including a red LED lamp, a green LED lamp, and a blue LED lamp. As shown in fig. 12 and fig. 13, the light sensor 3 can be implemented by a photodiode, one end of the photodiode is connected to 3.3V through a resistor 100K, the other end of the photodiode is connected to the ground, and the photodiode is connected to an ADC (analog-to-digital converter) detection pin 41 of the MCU (i.e., the controller 13) through a current limiting resistor. One end of the blue LED lamp is connected with the 23 rd pin of the MCU, and the other end of the blue LED lamp is connected with 3.3V. When the light source is not illuminated, the saturation reverse leakage current of the photosensitive diode is small, and when the light source is illuminated, the saturation reverse leakage current of the photosensitive diode is increased. Therefore, according to the change of the saturation reverse leakage current of the photodiode, the voltage read by the ADC of the MCU varies with the brightness of the light. When the ambient light intensity is too weak, the blue LED flickers for 10 times, and when the ambient light intensity is too strong, the blue LED is normally lighted for 10 seconds.
The spectacle frame 1 is further provided with an attitude sensor 14 and a vibration motor 9, the attitude sensor 14 and the vibration motor 9 are connected with a controller 13, the attitude sensor 14 is used for detecting the horizontal angle of the spectacle frame 1, and the controller 13 is used for driving the vibration motor 9 to send out a vibration alarm signal when the horizontal angle is continuously higher than a preset value and reaches a second time length. The attitude sensor 14 may be a six-axis inertial measurement unit, and specifically may be a six-axis inertial measurement unit of model BM 160. The BM160 six-axis inertial measurement unit integrates a 16-bit three-axis gravity accelerometer and an ultra-low power consumption three-axis gyroscope in a single package body, and adopts 14-pin LGA package, and the size is 2.5 multiplied by 3.0 multiplied by 0.8mm 3. When the triaxial gravity accelerometer and the triaxial gyroscope operate in a full-speed mode, the typical value of power consumption is as low as 950 muA, and the energy consumption is greatly reduced. As shown in fig. 10 and 11, the BM160 six-axis inertial measurement unit is connected to the 27 th pin and the 28 th pin of the MCU through an I2C interface as the attitude sensor 14. The vibration motor 9 is a flat motor and is driven by an NMOS (N-channel metal oxide semiconductor) tube, the driving voltage is taken from the voltage of the lithium ion rechargeable battery 11, and the driving IO port is connected to the 15 th pin of the MCU. When the horizontal angle is normal, the vibration motor 9 does not operate. When the lowering angle is larger than 15 degrees or the head-shake angle is larger than 15 degrees and the duration exceeds 60 seconds, the vibration motor 9 starts vibrating. If the user raises his head and looks straight ahead with his eyes during the vibration process, the horizontal angle detected by the attitude sensor 14 is returned to the normal range, and the vibration motor 9 automatically stops the vibration.
The light sensor 3 can be disposed on the inner side of the lens 2, and the ambient illumination intensity is the illumination intensity of the light in front of the lens 2 after passing through the lens 2. When light sensor 3 set up in lens 2 inboard, the illumination intensity behind lens 2 is passed through to the light in its environment illumination intensity that detects for the light in lens 2 the place ahead, shines the illumination intensity to user's eyes promptly, and this illumination intensity is the illumination intensity that people's eyes really accepted, consequently, the illumination intensity value that its detected when setting up light sensor 3 in lens 2 inboard is more meaningful for helping user's eyes to obtain comfortable illumination intensity. Of course, the light sensor 3 may also be disposed above the lens 2, and the ambient light intensity detected by the light sensor 3 is the light intensity in front of the lens 2, i.e. the light intensity irradiated onto the glasses, but not the light intensity irradiated onto the eyes of the user.
The electrochromic glass 6 and the photochromic glass 7 can be designed to have different transmittances at different parts in the non-fully transparent state, and specifically, the transmittances of the electrochromic glass 6 and the photochromic glass 7 are gradually increased from top to bottom in the non-fully transparent state. The aforementioned "up" and "down" are shown in fig. 1 and 2, i.e., above and below the vertical direction when the glasses are horizontally placed. Glasses made of the lens structure with the transmittance gradually increased from top to bottom are suitable for being worn during riding or driving at night, can effectively block the highlight directly emitted from far away, and do not influence the observation of a wearer to near places.

One end of the green LED lamp is connected with the 20 th pin of the MCU, and one end of the green LED lamp is connected with 3.3V. The charging insertion detection is connected to the 43 rd pin of the MCU after being divided by two resistors. When charging the lithium ion rechargeable battery 11, the 43 rd pin of the MCU detects a high level, the 11 th pin of the MCU detects a low level, and the red LED lights up to indicate that charging is underway. When the lithium ion rechargeable battery 11 is fully charged, the 11 th pin of the MCU detects a high level, the red LED lamp is turned off, and the green LED lamp is turned on. And one end of the ADC detection pin is connected with the anode of the lithium ion rechargeable battery 11, and the other end of the ADC detection pin is grounded.
