a liquid crystal lens 4, wherein the liquid crystal lens 4 is mounted in the frame; the liquid crystal lens 4 is electrically connected with the control module;

the distance sensor 7 is electrically connected with the control module, and the distance sensor 7 is used for transmitting a distance signal to the control module;

and the control module is used for comparing the received distance signal with a preset distance to control the change of the display state of the liquid crystal lens 4.

The working principle of the embodiment of the invention is as follows: when the glasses frame is worn, the glasses frame is erected in front of eyes of a user, glasses legs are worn on ears of the user, when the glasses frame is used, the infrared distance sensor 7 which can monitor the viewing distance in real time on the left side and the middle side of the glasses frame, when the viewing distance is too short, the controller controls the liquid crystal lens 4 to carry out frequency conversion, so that an image displayed by the liquid crystal lens 4 is blurred, the user needs to adjust the viewing distance, the viewing distance is in accordance with the proper distance, the liquid crystal lens 4 is recovered to a normal state, the user can control the sufficient viewing distance, and the occurrence of myopia of the user is effectively prevented; and the eyeshield layer that sets up in the 4 outsides of liquid crystal lens can make glasses have anti blue light, prevent tired function, and more comfortable when the user uses further prevents near-sighted emergence.

By adopting the technical scheme, the invention has the beneficial effects that: simple structure, reasonable in design through liquid crystal lens 4 as the lens, when the viewing distance is too close, 4 frequency conversion of liquid crystal lens make the image of demonstration become fuzzy, and the person of wearing needs the adjustment viewing distance to obtain clear image to can the effectual emergence of prevention person of wearing myopia.

As an optional implementation manner, in the first aspect of the embodiment of the present invention, the apparatus further includes a timing module electrically connected to the control module, where the timing module is configured to transmit a time signal to the control module; the control module is used for comparing the received time signal with preset time to control the change of the display state of the liquid crystal lens 4.

Specifically, when a user wears the intelligent glasses, a timing module is started to record time; since the eye-use duration has a great influence on users, particularly children, the embodiment of the invention is operated by combining timing with the liquid crystal lens 4; if the preset time is exceeded, for example, the time for reading a book exceeds 1 hour, the user should be reminded to take a rest to protect the eyes, if the voice reminding mode is tightly adopted, the user cannot always effectively complete the rest, and the user may not stop to take a rest for the eyes after the voice reminding, so that the corresponding effect cannot be always achieved even if the voice reminding mode is adopted. When the preset time duration is reached, the aim of reminding the user is fulfilled by adopting a mode of forcibly blocking the sight, namely when the corresponding time duration is reached, the light transmittance of the liquid crystal lens 4 is directly controlled to be reduced, namely the passing light is less, so that the image of the eyes of the user is finally blurred, the user is reminded of resting the eyes, and the occurrence of the shortsightedness of the wearer can be effectively prevented.

As an optional implementation manner, in the first aspect of the embodiment of the present invention, the glasses further include a key module 212 electrically connected to the control module, the key module 212 is disposed at one side of the glasses leg 2, and the control module is configured to switch the preset time according to a received key signal;

because the eye habits of different people are different, in order to adapt to the requirements of more users, the key module 212 is adopted to switch the preset time in the embodiment of the invention; for example, when the implementation is performed, 4 gears can be set, such as setting 40 minutes, 1 hour, 20 minutes and 1 hour, 40 minutes to set the preset time; when a user needs to switch, the corresponding content can be switched through the key, and generally, the time of initial use is 40 minutes; the gear is changed once per pressing, and when the device is specifically implemented, a loudspeaker can be arranged to broadcast time of the device, so that a user can know the current specific set time.

In order to enable the scheme of the invention to be more convenient to operate, a Bluetooth module can be arranged to perform data interaction with a user mobile phone end; the user can adjust the corresponding preset time through the mobile phone app, and a stepless adjusting mode can be realized through the mobile phone app, and any numerical value from 1 minute to 3 hours can be set. Specifically, the bluetooth module may be disposed on the PCB circuit board 6, and then electrically connected to the battery through the first flexible connecting line 51 and the control module.

When the method is specifically implemented, corresponding reading time or reading distance and the like can be set through the mobile phone app; more preferably, during implementation, the bluetooth module may be in communication connection with the intelligent terminal, for example, the bluetooth module may be electrically connected with a tablet computer; when the user is watching the network course, when the liquid crystal lens at the intelligent glasses is detected to be in the atomizing state, the control signal can be sent to the tablet personal computer to control the network course to pause, and after a period of time, the corresponding control signal is sent to be opened to realize linkage of the intelligent glasses and the tablet personal computer.

As an optional implementation manner, in a first aspect of the embodiment of the present invention, fig. 7 is a schematic flowchart of a process of using an eye reminder provided in the embodiment of the present invention, and as shown in fig. 7, the control module is configured to execute the following steps:

s101: acquiring distance information detected by a distance sensor 7;

s102: matching corresponding reminding time with a preset mapping table according to the distance information;

s103: when the reminding time is up, a corresponding control signal is sent to the liquid crystal lens 4 to control the display state of the liquid crystal lens 4.

In particular, different distances correspond to different suitable reading times; for example, when the reading distance is 33cm, the user may be recommended to read for 1 hour and twenty minutes; when the reading distance of the user is 30cm, the reading time of the user can be recommended to be 1 hour, and when the reading distance of the user is too close, the liquid crystal lens can be directly controlled to be in the atomizing state to achieve the purpose of reminding.

During specific matching setting, a range matching mode can be performed; for example, the preset mapping table may be: the reading time is 1 hour corresponding to 30-33 cm; the reading time of 25-30cm is 40 minutes; when the distance is less than 25cm, the user is directly reminded; and correcting the reading posture of the user. Specifically, a formula matching mode can be adopted, namely each distance corresponds to one reading time length, and more accurate time adjustment can be realized.

Besides the adjustment in the above manner, the corresponding light intensity can be obtained through the light sensor, because if the desk is in a dark environment, the eyes of the user are also greatly affected, when the desktop illumination is less than 250 lux, the user is reminded of using the eyes, and when the desktop illumination is greater than 300 lux, the time adjustment is not needed according to the illumination.

the embodiment of the invention can also be provided with the light sensor to detect the light signal of the current environment, and if the light sensor is in a weak light environment, the eyes of a user are easy to be tired; in specific implementation, different preset durations may be adjusted according to different ambient light intensities, for example, when the first ambient light intensity interval is in, the preset duration is set to 40 minutes, when the first ambient light intensity interval is in, the preset duration may be set to 1 hour, and when the third ambient light intensity interval is in, the preset duration may be set to 1 hour and 20 minutes; when the detected ambient light intensity is smaller than a certain numerical value, the liquid crystal lens 4 is controlled to be in the atomizing state, and a user is reminded to improve the ambient light brightness.

And/or, the liquid crystal display further comprises a stroboscopic switch electrically connected with the control module, and the stroboscopic switch is used for controlling the display state of the liquid crystal lens 4.

The liquid crystal lens 4 is controlled by a strobe switch to carry out strobe operation at 5HZ or 10 HZ; when the preset time is detected, the embodiment of the invention can also control the current to be transmitted to the lens, and the lens can be darkened or become transparent under the action of the current. After the signal is input, the lens flickers for only 0.1 to 0.2 seconds, which does not cause discomfort to eyes and can relieve eye tension. Through the stroboscopic mode, on one hand, the eye using reminding of the user can be realized, and on the other hand, the eye fatigue of the user can be relieved.

As an optional implementation manner, in the first aspect of the embodiment of the present invention, the smart glasses further include a power module 5 electrically connected to the control module, and a charging interface electrically connected to the power module 5, where the power module is used to supply power to the smart glasses, and the power module is a lithium battery;

The power module 5 is arranged on the charging interface which is a magnetic suction charging interface 211, and the power module 5 is electrically connected with the control module through a second flexible connecting wire 411.

The power module 5 supplies power to the whole intelligent glasses; the magnetic attraction manner is adopted, so that the charging of a user is more convenient, and when the magnetic attraction charging interface 211 is implemented specifically, a magnetic induction module can be arranged at the position of the glasses frame corresponding to the magnetic attraction charging interface 211, so that when the user folds the glasses, the closing operation can be automatically realized; the service life of the battery is prolonged.

As an alternative implementation manner, in the first aspect of the embodiment of the present invention, the glasses frame 1 includes a left glasses frame 11 and a right glasses frame 12, the temple 2 includes a left temple 21 and a right temple 22, the left temple 21 is rotatably connected to the left glasses frame 11, the right temple 22 is rotatably connected to the right glasses frame 12, and the left glasses frame 11 and the right glasses frame 12 are fixedly connected through the connecting portion 3;

still include the angle sensor with control module electric connection, angle sensor sets up and is used for detecting the inclination of glasses in the picture frame.

The posture of the user is detected through the angle sensor, for example, when the user reads, if the posture is incorrect, the situation of high and low shoulders is easily generated in the past; therefore, in the embodiment of the invention, the attitude detection is carried out by adopting the angle sensor, and when the attitude of the user is detected to be incorrect, the user is reminded in time. In the embodiment of the present invention, the angle sensor may have two different forms, one is to directly use the gyroscope for angle detection, and the other is to use two infrared sensors for detection.

The first blocking part and the second blocking part are arranged to realize the function of the frame, namely, a user wearing the myopia glasses 8 can wear the glasses; the specific blocking part is mainly used for being matched with an external myopia lens 8, so that the two lenses are fixed in the wearing process, the relative sliding is reduced, and the use scene is improved. The setting mode of above-mentioned block portion can adopt the setting mode of annular setting square or buckle or the setting mode of unilateral recess to go on, and its purpose is in order to make near-sighted user wear more convenience. When the user who wears spectacles wears above-mentioned glasses, the user can directly carry out the cover frame operation with this intelligent glasses with its spectacles for both are fixed, finally make it can adapt to more extensive crowd's demand and use.

As an optional implementation manner, in the first aspect of the embodiments of the present invention, the liquid crystal lens 4 includes a liquid crystal dimming layer 41, the liquid crystal dimming layer 41 includes a PDLC liquid crystal film or a PSLC liquid crystal film, and the liquid crystal dimming layer 41 is electrically connected to the control module through a second flexible connection line 411;

the liquid crystal lens further comprises a protective layer 42, and the protective layer 42 is positioned below the liquid crystal dimming layer 41; the protective layer 41 is any one of a tricarboxylic acid fiber film, a polycarbonate film, or a thermoplastic polyester film.

The light adjusting film (PDLC) in the examples of the present invention is an interpretive polymer dispersed Liquid Crystal. As the name implies, the light modulation film is a film capable of adjusting the light passing state. It works mainly between a scattering state and a transparent state, i.e. the film itself can be changed between a transparent and a non-transparent state (the visual effect is close to frosted glass), the transparency being regulated by a voltage.

The basic principle is as follows:

1. when the light-adjusting film is powered off, the polymer liquid crystal materials in the light-adjusting film are arranged in disorder, so that light cannot penetrate through the film, and the observed effect is a milky opaque state, namely an atomized state.

2. When the light-regulating film is powered on, the polymer liquid crystal material in the middle of the film is orderly arranged under the action of an electric field, so that light can penetrate through the film, and the observed effect is a transparent and colorless film state. The switching between the atomizing state and the transparent state is realized by controlling the power on and off; specifically, that is, when the preset time is reached, the power-off can be controlled to realize the atomization operation on the liquid crystal lens 4, and then the user can be reminded by eyes.

The PDLC is a liquid crystal high polymer which is formed by UV curing of liquid crystal resin sandwiched between two ITO transparent conductive films. Due to the dielectric anisotropy of the liquid crystal, the refractive indexes of the liquid crystal and the resin are consistent after the liquid crystal is electrified, the transparency (the transmittance is more than 75%) is realized, the liquid crystal is irregularly arranged after the power is off, the refractive indexes of the liquid crystal and the resin are different, and the liquid crystal is in a fog state, namely a frosted state. A fast switching between transparent and frosted is achieved. The PDLC liquid crystal film further comprises a cold buried resin edge sealing layer arranged on the PDLC structure layer, two sides of the thickness direction of the PDLC structure layer are respectively provided with an adhesive layer, and the cold buried resin edge sealing layer and the adhesive layer form a closed space for sealing the PDLC structure layer. And part of the cold-buried resin edge sealing layers are positioned on two sides of the PDLC structure layer in the thickness direction and cover two sides of the PDLC structure layer in the thickness direction together with the rubber clamping layer.

The embodiment of the invention can also adopt a PSLC liquid crystal film for operation, and when the PSLC liquid crystal film is adopted, the specific implementation mode is opposite to that of the PDLS liquid crystal film; the PSLC is in the atomizing state when being powered on and in the transparent state when being powered off, and the mode of adopting the PSLC liquid crystal film in the embodiment of the present invention is more preferable, because the time of being in the transparent state is longer in the process of using the glasses, and the service life of the whole is longer when adopting the PSLC liquid crystal film.

In addition to the two liquid crystal films, in the implementation, a liquid crystal film with a changed transmittance may be used, that is, the transmittance of the liquid crystal film is any value of 1% to 100%.

As an optional implementation manner, in the first aspect of the embodiment of the present invention, the liquid crystal lens 4 further includes a blue light prevention layer 43, the liquid crystal dimming layer 41, the protective layer 42, and the blue light prevention layer 43 are sequentially stacked to form the liquid crystal lens 4, and the blue light prevention layer 43 adopts a blue light prevention film;

since the strength of the liquid crystal lens 4 is not particularly high, if an unexpected situation occurs during use, a situation in which the liquid crystal lens 4 is easily chipped occurs; because it is in the region of the eyes, if fragmentation occurs, the user's eyes may be compromised, causing even greater injury; therefore, in the embodiment of the present invention, the protective layer 42 is used to protect the eyes of the user, and even if the liquid crystal lens 4 is accidentally cracked, the protective layer 42 does not substantially affect the eyes of the user. Specifically, the protective layer 42 is a TAC film or a PC sheet, which has good toughness and can effectively protect the eyes of the user. The eyeshield layer that 4 outsides of liquid crystal lens set up can make glasses have anti blue light, prevent tired function, and more comfortable when the user uses further prevents near-sighted emergence.

In actual use, a user can use a mobile phone, a computer or a tablet personal computer to log on a lesson, so that the user has a better radio reception effect; the corresponding communication connection is realized by adopting a mode that a Bluetooth headset at the intelligent glasses is matched with an intelligent terminal; finally, the content played at the intelligent terminal is transmitted to the ears of the user through the Bluetooth headset, and the overall use scene is improved.

The foregoing is considered as illustrative of the preferred embodiments of the invention and technical principles employed. The present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention. Therefore, although the present invention has been described in more detail by the above embodiments, the present invention is not limited to the above embodiments, and may include other equivalent embodiments without departing from the spirit of the present invention, and the scope of the present invention is determined by the scope of the claims.
