DETAILED DESCRIPTION
[0018] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0019] Please refer to Figs. 1-3The utility model provides a technical scheme: a child myopia prevention and control glasses mainly includes mirror frame, atomization PNLC lens 4, first glasses leg 6 and second glasses leg 7, the mirror frame is the main body support structure of glasses, provides the installation foundation for other components, the atomization PNLC lens 4 is the core optical component of realizing myopia prevention and control function, first glasses leg 6 and second glasses leg 7 are hinged in the both sides of mirror frame respectively, and the user can adjust the opening angle of glasses leg according to the head size and wearing comfort of oneself.
[0020] The mirror frame is composed of the front mirror frame 1 and the rear mirror frame 2 that are buckled with each other. The front mirror frame 1 and the rear mirror frame 2 are connected in a buckling mode, which facilitates assembly and disassembly and also ensures the overall strength and stability of the mirror frame. The inner mirror frame 3 is fixed between the front mirror frame 1 and the rear mirror frame 2, and provides a special mounting position for the atomization PNLC lens 4, ensuring stable lens mounting.
[0021] The soft wire 5 is also arranged between the front mirror frame 1 and the rear mirror frame 2. The soft wire 5 has good flexibility and conductivity, and can power the atomization PNLC lens 4, the distance sensor 8 and the light sensor 9 to make them work normally. At the same time, the soft wire 5 can also transmit the communication signals of the distance sensor 8 and the light sensor 9, accurately transmitting the data detected by the sensors to the circuit board 71 for processing. The power connection parts at both ends of the soft wire 5 are connected with the power connection ends of the battery 62 and the circuit board 71 respectively, thereby realizing the conduction of the entire glasses circuit.
[0022] The nose holder 10 is installed on the back of the rear mirror frame 2. The design of the nose holder 10 conforms to the principle of ergonomics, can closely fit the user's nose bridge, provide a comfortable wearing experience, and ensure that the glasses remain stable during wearing and are not easy to slip off.
[0023] The atomization PNLC lens 4 is installed inside the inner mirror frame 3. The lens is made of special materials and processes, and presents a transparent structure before being powered on, so that the user can clearly see external objects. When powered on, the lens will undergo a fogging phenomenon and become blurred. The atomization PNLC lens 4 adopts existing technology, and the specific structure and principle are not described here. This feature enables the glasses to remind the user to adjust eye habits by fogging the lens under certain conditions, thereby achieving the purpose of preventing and controlling myopia.
[0024] The first temple 6 is provided with a magnet 61 and a battery 62. The magnet 61 cooperates with a Hall switch 74 in the second temple 7 to realize the power-on and power-off functions of the glasses. When the first temple 6 and the second temple 7 are normally closed, the magnet 61 is close to the Hall switch 74, the Hall switch 74 senses the change of the magnetic field, triggers the circuit to be turned on, and the glasses are powered on; when the first temple 6 and the second temple 7 are opened at a certain angle, the magnet 61 is away from the Hall switch 74, the magnetic field disappears, the circuit is turned off, and the glasses are powered off. The battery 62 provides power support for each electronic element of the glasses to ensure its normal operation.
[0025] The second temple 7 is provided with a circuit board 71 and a vibration motor 72. The circuit board 71 is the electronic control center of the glasses, and the gyroscope 73, the Hall switch 74 and the charging interface 75 are respectively integrated on the circuit board 71. The circuit board 71 can supply power to the gyroscope 73, the Hall switch 74 and the vibration motor 72, and can control and process the data collected by the sensor accordingly.
[0026] The vibration motor 72 vibrates at the moment when the glasses are powered on and powered off. When the glasses are turned on (powered on), the vibration motor 72 vibrates to remind the user that the glasses have been normally started; when the glasses are turned off (powered off), the vibration motor 72 vibrates again to inform the user that the glasses have been turned off. This vibration reminding method is intuitive and effective, and is convenient for the user to know the working state of the glasses in time.
[0027] The gyroscope 73 is used to detect the angle of the glasses in the use state. When a child wears the glasses, if the head angle is abnormal, for example, the head is tilted or the angle of the head is greater than 25°, the gyroscope 73 will detect the change of the angle and transmit the signal to the circuit board 71. After processing by the circuit board 71, the atomized PNLC lens 4 is powered on to atomize, so that the glasses cannot be used continuously, thereby reminding the child to adjust the sitting posture and preventing myopia caused by improper eye posture.
[0028] A through hole is provided at the bottom of the second temple 7 for the charging connector to be inserted into the charging interface 75. The charging interface 75 is used to charge the battery 62. When the battery is low, the user can connect an external power source to the charging interface 75 to supplement the power of the battery, so as to ensure that the glasses can be used continuously and normally.
[0029] A reserved slot 11 is provided on the front surface of the front frame 1, and a distance sensor 8 and a light sensor 9 are respectively installed in the reserved slot 11. A transparent protective cover 12 is installed on the front surface of the reserved slot 11. The protective cover 12 can not only protect the distance sensor 8 and the light sensor 9 from being collided and damaged by external objects, but also will not affect the normal distance measurement and light intensity detection of the sensors due to its transparent property.
[0030] The distance sensor 8 can detect the distance from the glasses to the object in real time. When the distance is detected to be too close, it means that the user may be too close to the object such as a book or an electronic screen, and there is a risk of myopia. At this time, the distance sensor 8 transmits a signal to the circuit board 71, and the circuit board 71 controls the fogging PNLC lens 4 to be powered on to fog, reminding the user to adjust the distance.
[0031] The light sensor 9 can detect the intensity of ambient light. When the ambient light is too strong or too weak, it will cause harm to the user's eyes and increase the likelihood of myopia. The light sensor 9 transmits the detected light intensity signal to the circuit board 71, which makes a judgment according to the preset light intensity threshold. If the light intensity exceeds the normal range, the circuit board 71 controls the fogging PNLC lens 4 to be powered on to fog, reminding the user to improve the eye environment.
[0032] In operation: when the user wears the child myopia prevention glasses of the present application, the glasses are in standby state. When the first lens leg 6 and the second lens leg 7 are closed, the magnet 61 is close to the Hall switch 74, and the glasses are powered on. At this time, the distance sensor 8 and the light sensor 9 start to work, and the distance from the glasses to the object and the intensity of the ambient light are detected in real time. The gyroscope 73 also starts to detect the angle of the glasses.
[0033] In normal use, if the distance sensor 8 detects that the distance is too close, or the light sensor 9 detects that the ambient light is too strong or too weak, or the gyroscope 73 detects that the head angle is abnormal (such as tilting the head or the angle of the head is greater than 25°), the circuit board 71 will receive the corresponding signal and control the fogging PNLC lens 4 to be powered on to fog. After the lens is fogged, the user cannot clearly see the external object, so as to realize that there is a problem in the user's eye habits or posture, and then actively adjust.
[0034] When the user finishes using the glasses and opens the first lens leg 6 and the second lens leg 7 to a certain angle, the magnet 61 is away from the Hall switch 74, the glasses are powered off, and the vibration motor 72 vibrates to remind the user that the glasses have been turned off.
[0035] When the battery is low, the user can charge the battery 62 through the charging interface 75 to ensure that the glasses can be used normally at any time.
[0036] Finally, it should be noted that the circuit connection structure of each electronic component and the arrangement of the circuit are all known technologies, which will not be described in detail here.
