Description

Technical Field

[0001] The invention relates to the technical field of glasses, and in particular to a pair of liquid crystal screen fogging glasses. Background Art

[0002] At present, there are many kinds of functional glasses. Application publication number CN113234452A - A liquid crystal composition and its application introduces the application of PDLC (polymer dispersed liquid crystal) as a liquid crystal composition for preventing myopia glasses. PDLC needs to be powered on for a long time to maintain a clear state, the overall power consumption is high, and the transmittance of the clear state is low. It provides a fast-response trans-PNLC liquid crystal composition. By applying trans-PNLC technology, it can maintain a transparent state when the power is off and a frosted state when the power is on, and the switching speed between the two states is fast. Since transparent display can be achieved without power, the power consumption is low. The liquid crystal composition is used in the lenses of glasses for preventing myopia. Switching between the clear state and the foggy state serves to remind the user that the sitting posture is not correct. Using this liquid crystal material, under ultraviolet light irradiation, the RM (reactive monomer) molecules produce a certain network. Since the refractive index of the RM molecules in the initial arrangement is consistent with that of the liquid crystal molecules, the lens remains in a clear state (transparent) at this time. When electricity is applied to the lens, the refractive index of the liquid crystal molecules is different from that of the polymer, so a foggy state (blur) is produced.

[0003] In order to improve the ability to control the lenses, when developing products to prevent myopia, it is necessary to consider the user's eye habits and posture, so as to control whether the lenses become blurred to achieve the purpose of warning, so as to keep the user in a reasonable eye posture during wearing and not too close to the mobile phone or book.

The temples 3 are hinged (using conventional hinge connection methods) on either side of the frame 1. The LCD screen lens 2 is fixed to the frame 1. A lithium battery 4 is located in one temple 3. This arrangement balances the weight of the left and right temples 3, allowing the lithium battery 4 to fully occupy the space within one temple 3. This results in a larger lithium battery 4 and a higher power capacity, ensuring battery life. A circuit module 5 is located in the other temple 3, and a distance sensor module 6 is located in the center of the frame 1.

The circuit module 5 includes a charging interface 51 , a power management module 52 , a power switch 53 , a microprocessor module 54 , and a driving module 55 .

[0033] The microprocessor module 54 can be a single-chip microcomputer circuit. In this case, the nRF52832 (Bluetooth module, capable of Bluetooth communication) model can be selected. Signal processing is implemented through its application circuit. It can process signal magnitude judgment and comparison, output high-level signals, and control MOS tube switching.

[0034] The driving module 55 can be as follows Figure 4As shown, signal terminal SYS-PWR is the power supply signal output by power management module 52. It is provided to the positive electrode of LCD lens 2 via resistor R12 and then connected in parallel to the positive and negative electrodes of LCD lens 2 via diode D3 to prevent reverse current. Transistor Q2 is used to control whether the negative electrode of LCD lens 2 is grounded. An output pin of microprocessor module 54 is connected to the base of transistor Q2 via resistor R15. The high and low voltage levels from control terminal CTL control transistor Q2 on and off, switching the LCD lens 2 between blurred and clear states.

[0035] The power management module 52 is mainly used to control the charge and discharge of the lithium battery 4. The existing power management module 52 can be used, with a charging specification of 5V and a discharging output voltage of 3.3V.

[0036] The charging port 51 is connected to a power management module 52, which is connected to the lithium battery 4 and controls the charging and discharging of the lithium battery 4. The power management module 52 provides operating power to the microprocessor module 54 via a power switch 53. The power switch 53 responds to the opening and closing of the temple 3, turning the power on when the temple 3 is open and off when the temple 3 is closed. Turning the power on and off by opening and closing the temple 3 saves energy and prevents the user from forgetting to turn off the power. Turning off the temple 3 is easy and convenient.

[0037] The distance sensing module 6 is connected to the microprocessor module 54 to provide a sensing signal. The LCD screen lens 2 is connected to the microprocessor module 54 via the driver module 55. If an obstacle is within the sensing distance, a sensing signal is output. The microprocessor module 54 receives the sensing signal and controls the LCD screen lens 2 to a blurred state through the driver module 55. Otherwise, the LCD screen lens 2 remains clear.

[0038] Specific distance sensing module 6 reference Figure 5 As shown, signal PW-SW is generated by microprocessor module 54 and can control the PMOS transistor to turn on or off. Voltage source VCC-3V3 represents a 3.3V power supply, which is provided to the first pin of chip U4 via the PMOS transistor. This first pin, VDD, is the power supply pin, thereby controlling whether chip U4 is powered and operational. Chip U4 is a distance sensing sensor. Capacitor C20 is connected to the first and third pins of chip U4 for filtering. In addition, another power supply signal VCC-SENSOR for the sensor is connected to the sixth and fourth pins of chip U4d via resistors R6 and R7. Pin 4 of chip U4 is used to output a sensing signal, LTR-INT. This signal terminal is connected to an input pin of the microprocessor, thereby obtaining a determination of distance detection by control chip U4.

[0039] Furthermore, the maximum sensing threshold of the distance sensing module 6 is adjustable within a range of 30 cm to 40 cm.

[0040] Based on the above scheme, the circuit module 5 also includes a touch detection module 58, which is connected to the microprocessor module 54 for providing a touch signal. The maximum sensing threshold of the distance sensing module 6 is adjusted according to the touch signal, and is set with a first gear, a second gear and a third gear. The first gear is set to 30 cm, the second gear is 35 cm, and the third gear is set to 40 cm.

[0041] The touch detection module 58 may be a capacitive touch switch (touch sensor). Preferably, when the touch detection module 58 triggers two consecutive touch signals or a touch signal lasting more than 2 seconds, the microprocessor module 54 determines that the gear is switched.

[0042] The circuit module 5 is further connected to an indication module 56 , and the microprocessor module 54 is connected to the indication module 56 . The indication module 56 includes a first indicator light 561 , a second indicator light 562 and a third indicator light 563 , which are blue, yellow and red respectively.

[0043] When the power switch 53 is powered on, the indicator module 56 is powered off; when the power management module 52 determines that the power level of the lithium battery 4 is less than 20%, the second indicator light 562 flashes to indicate; when the power level is less than 10%, the third indicator light 563 flashes to indicate.
