Detailed Description

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, specific embodiments of the present invention will be described below with reference to the accompanying drawings. It is to be understood that the drawings in the following description are merely exemplary of the utility model and that other drawings and embodiments may be devised by those skilled in the art without the use of inventive faculty.

In a first embodiment of the present invention, an intelligent eyewear 100 for preventing and controlling bad eyes comprises: a frame body configured with a PNLC zone lens 110, the PNLC zone lens 110 comprising a plurality of independent zones; two glasses legs which are respectively connected with two ends of the glasses frame main body; a bad-eye prevention and control parameter sensing module 120, configured on the frame body or the temple, for sensing bad-eye prevention and control parameters; the main control module 130 is disposed in the frame body or the temple, and is connected to each of the zones in the PNLC zone lens 110 independently and the bad eye prevention and control parameter sensing module 120, for controlling the fogging state of each zone in the PNLC zone lens 110 according to the bad eye prevention and control parameter, and the control chart is shown in fig. 1.

In this embodiment, the frame body may include a plurality of components, including a frame, a nosepiece, etc., in addition to the PNLC zone lens 110. Two mirror legs are first mirror leg and second mirror leg respectively, and wherein, the one end and the first mirror leg of mirror holder main part are connected, and the other end is connected with the second mirror leg, and two mirror legs can be connected with the one end of mirror holder main part respectively through the connecting piece of arbitrary form.

Each partition in the PNLC partition lens 110 is independently connected to a corresponding control terminal in the main control module 130, and is connected to a common terminal of the main control module 130 to access a common potential. The shape and number of the partitions in the PNLC partition lens 110 are not limited here, and may be configured according to actual requirements, as long as independent control of each partition is realized according to a control line corresponding to the partition design. In order to realize the purpose of zone control, the PNLC zone lens 110 includes a first glass layer and a second glass layer which are attached to each other, and PNLC liquid crystal filled between the first glass layer and the second glass layer, a control circuit is etched on the glass layers, and the atomization control of the PNLC liquid crystal between the first glass layer and the second glass layer of each zone is realized through the control circuit, including controlling the PNLC liquid crystal to enter an atomization state and controlling the PNLC liquid crystal to eliminate the atomization and change the PNLC liquid crystal into a full transparent state.

In the process of controlling the PNLC partition lens 110 to enter into atomization, a PWM modulation signal is output to the common terminal through a control line, and a level opposite to the common terminal is output to an area control terminal (the partitions of the PNLC partition lens 110 share the common terminal, and each partition includes an area control terminal), so as to form a pressure difference with gradually increasing duty ratio, so as to gradually atomize the partitions in the PNLC partition lens. In the process of controlling the PNLC partition lens 110 to enter the transparent state, the PWM modulation signal is output to the common terminal through the control line, and the same level as the common terminal is output to the area control terminal (the partitions of the PNLC partition lens 110 share the common terminal, and each partition includes an area control terminal), so as to form a pressure difference with gradually decreasing duty ratio, so as to make each partition in the PNLC partition lens gradually transparent.

In one embodiment, the first glass layer and the second glass layer are made of ITO glass, and in the zoning process, the ITO glass is subjected to exposure, development, acid etching and other steps to divide the ITO glass into an inner zone and a plurality of outer zones, and the zones are subjected to wiring design, so that the finally formed PNLC zone lens 110 achieves the purpose of zone atomization. The control circuit can adopt a flexible circuit board design, and wiring is carried out according to the control requirement, and particularly when partial subareas need to be controlled, only the subareas which need to be subjected to atomization control are wired. If only the outer ring partition is subjected to wiring design, part of the inner ring partition is left empty, so that the inner ring has better permeability, and the purpose of reminding a user can be achieved while the influence on the video is small. For another example, if only the inner ring subarea is wired, a part of the outer ring subarea is left empty, so that the purpose of reminding a user and the function of blocking light rays are achieved.

As shown in fig. 2, which is a schematic structural diagram of an example PNLC zone lens 110, it can be seen that a single lens includes 4 zones, which are zone 1, zone 2, zone 3 and zone 4 in sequence from the outer circle to the inner circle, and the 4 zones have independent control circuits respectively corresponding to SEG1, SEG2, SEG3 and SEG4 in the figure and share a common terminal COM. In other examples, the number of zones may be adjusted according to the size of the lens when performing inner and outer zone zoning, or even a single lens may be controlled as a zone.

In order to satisfy the diversified demand of user to glasses, in other embodiments, intelligence is bad prevents controlling glasses 100 with eyes still possesses and prevents the blue light function, and PNLC subregion lens 110 surface still has the blue light inoxidizing coating promptly, realizes preventing the blue light function through the membrane material reflection. For the blue light protection layer, the light transmittance requirement is as follows: the whole light transmittance reaches more than 80 percent. The transmittance is higher than 80% for the blue light wave band above 455 nm; the transmittance of the 415-445nm short-wave harmful blue light is lower than 80%, and the transmittance of the 385-415nm blue-violet light is lower than 75%. The requirement of the light filtering rate is as follows: the whole light filtering rate is about 20% and not more than 25%. In addition, the intelligent eye protection and control glasses 100 for bad use can meet the requirements for functions of explosion prevention, fingerprint prevention, oil stain prevention, scratch prevention, water prevention, static electricity prevention, reflection reducing film, UV resistance and the like, and corresponding treatment can be performed on the surface of the PNLC zone lens 110, for example, the surface of the PNLC zone lens 110 is attached with an anti-fingerprint layer to realize the fingerprint prevention function, and the surface of the PNLC zone lens 110 is attached with an anti-explosion layer (ARAF anti-explosion layer and the like) to realize the functions of reflection reducing film, fingerprint prevention, explosion prevention and the like.

In the process of preventing and controlling the bad eyes, the bad eye prevention and control parameter sensing module 120 senses the bad eye prevention and control parameters, and the main control module 130 controls the atomization state of each partition in the PNLC partition lens 110 according to the bad eye prevention and control parameters.

In one embodiment, the eye-ward parameter sensing module 120 includes a distance sensing module disposed on the surface of the frame body for sensing a distance parameter between the target object and the frame body in the disposition direction and sending the distance parameter to the main control module 130. After receiving the distance parameter, the main control module 130 compares the distance parameter with a preset distance threshold, and when the sensed distance parameter is smaller than the preset distance threshold, it is determined that the distance is in a too close state currently, and the main control module 130 starts to control each partition in the PNLC partition lens 110 to enter a fogging state; and when the sensed distance parameter is not less than a preset distance threshold, judging that the current state is normal. The preset distance threshold value can be set according to actual conditions, such as 20cm, 30cm and the like, or even farther; in addition, the preset distance threshold may also be an interval value (e.g., 5-30 cm), and when the sensed distance parameter changes between interval values, it is determined that the distance is in a too close state. In an improvement of this embodiment, the main control module 130 includes a timing unit, a duration determining unit and an atomization control unit, in addition to a parameter comparing unit for comparing the distance parameter sensed by the distance sensing module with a preset distance threshold, wherein the timing unit is configured to start timing when the parameter comparing unit determines that the current distance is in a too-close state; the duration judging unit is used for judging whether the duration time of the too-close state is greater than a first preset time threshold value; the atomization control unit is used for respectively controlling each subarea to enter the atomization state according to a preset rule when the duration time of the state duration judged by the duration time judging unit is greater than a first preset time threshold, and the division rule of the independent subarea of the PNLC subarea lens, the sequence of the subareas entering the atomization state under different division rules and the atomization time. The first preset time threshold may be set according to actual conditions, for example, set to 3s, 4s, or even more. The distance sensing module is a distance sensor and can be arranged in the middle of the spectacle frame main body, namely above the nose pad and in the middle of the two lenses, so that the accuracy of sensing data is improved.

Independent subareas of the PNLC subarea lens can be divided according to actual application requirements, and any scheme for realizing the purpose of preventing and controlling bad eyes by further controlling the atomization state of each subarea through the PNLC in the lens after the lens is divided is included in the embodiment, such as:

1) dividing a single lens into an inner ring subarea and a plurality of outer ring subareas which are mutually surrounded in a nesting mode, wherein when 0 outer ring subarea is divided, the whole lens is regarded as the inner ring subarea; when 1 inner ring partition and one outer ring partition are divided, the inner ring partition is nested in the outer ring partition; when the inner ring partition and the outer ring partition are divided into 1, the outer ring partitions are nested layer by layer, and the inner ring partition is nested in the innermost outer ring partition. In the PNLC zone lens shown in fig. 2, a single lens is divided into 1 inner ring zone (zone 4) and 3 outer ring zones (zone 1, zone 2 and zone 3), wherein the zone 1 is the outermost outer ring zone, the zone 2 is the middle outer ring zone, and the zone 3 is the innermost outer ring zone, as shown in the figure, the zone 4 is nested in the zone 3, the zone 3 is nested in the zone 2, the zone 2 is nested in the zone 1, so that 3 outer ring annular zones are formed by nesting, and the direction of the zone 1 pointing to the zone 4 is the outer ring to inner ring direction. In this partition manner, the shape of each partition is not particularly limited, and may be a regular shape or an irregular shape. In practical application, for convenience of etching, partitions with regular shapes may be formed, for example, the outer ring shape of the outer ring partition and the outer ring shape of the inner ring partition are both circular/elliptical/regular polygon, etc.; for another example, the outer ring of the inner ring partition is circular/elliptical, and the outer ring of the outer ring partition is regular polygon; for another example, the outer ring of the outer ring partition is circular/elliptical, and the outer ring of the inner ring partition is regular polygon. When a plurality of outer ring segments are included, the outer ring shape of each outer ring segment may be the same or different. In order to improve the interest, the partition with an irregular shape can be selectively formed, for example, an inner ring partition with a certain animal shape is formed; for another example, as shown in fig. 2, the inner ring zone and the outer ring zone are formed in corresponding shapes according to the shape of the lens. To facilitate common-end routing for each zone and to be more ergonomic, a single lens may be divided into 1-4 circle zones, and particularly into 4 zones including 1 inner circle zone and 3 outer circle zones as shown in fig. 2.

2) A plurality of independent subareas are formed on a single lens in a blocking mode, and the shape of each subarea is not particularly limited in the partitioning mode, and can be a regular shape or an irregular shape. For example, a single lens is divided into four block-shaped subareas of upper left, upper right, lower left and lower right; for another example, a plurality of (1, 2, 3, 4, etc. or even more) mutually independent square partitions are etched on the lens; for another example, a plurality of stripe-shaped partitions (2, 3, etc. or even more) parallel to each other in the transverse/longitudinal direction are etched on the lens.

In the above two divisional division methods, the respective sections are independent from each other, that is, the outermost circles of the divisional sections do not intersect with each other, and in other divisional methods, the divisional sections may be formed so as to intersect with each other, for example, by etching two intersecting circular regions on the lens to finally form 3 control divisional sections (including an intersecting region and a non-intersecting region of the two circular regions), and so on, as long as the finally formed divisional sections can facilitate the wiring and the divisional control.

The sequence of the atomization state of each partition can be set according to the actual situation, in order to improve the user experience, the atomization control can be performed on the partitions one by one according to the arrangement mode, and the atomization control can also be performed on the partitions in a grouping mode according to the arrangement mode (even all the partitions can be divided into 1 group for synchronous control). For example, when a single lens is divided into an inner ring partition and a plurality of outer ring partitions which are mutually surrounded in a nested manner, the progressive atomization from the outer ring partition to the inner ring partition can be adopted to control in the atomization state process; correspondingly, in the process of entering the transparent state, the inner ring subarea and the outer ring subarea are controlled to be transparent step by step. For another example, when a plurality of independent partitions are formed on a single lens in a partitioning manner, in the atomizing state, the progressive atomizing manner from left-to-right/top-to-bottom/outer-ring partitions to inner-ring partitions and the like can be adopted for control; correspondingly, in the transparent state, the control is carried out in a mode of from right to left/down to up/inner ring block to outer ring block and the like. In addition, in practical application, only part of the partitions can be subjected to atomization control, and the partitions needing the atomization control can be subjected to wiring control. The time for each partition to gradually enter the atomization state from the transparent state and gradually enter the transparent state from the atomization state can also be adjusted according to actual conditions, for example, 4s, 5s, 7s or more, and in order to improve user experience, the time for gradually entering the transparent state from the atomization state can be designed to be shorter than the time for gradually entering the atomization state from the transparent state.

In one example, a single lens includes 4 zones as shown in fig. 2 (zone a, zone B, zone C, and zone D from outer to inner). When the distance sensing module detects that the distance between the distance sensing module and the front target object is between 5 and 30cm and the state lasts for 3s, it is determined that the distance is in the too close state, the main control module 130 controls the two lenses to gradually change fog from the outer ring to the inner ring at the same time, and completely change fog within 8s (area a is completely atomized), and performs forced reminding, and the change of the haze corresponding to different times is shown in table 1, wherein Hmax represents peak haze, Eg: Hmax 25% represents 1/4 of the peak haze, that is, the percentage of the haze in the table represents the percentage of the peak haze Hmax.

Table 1: haze change table corresponding to different times in distance sensing

Time of day	Area and haze
		3-4s	A:0-25％、B:0、C:0、D:0
4-5s	A:25％-50％、B:0-25％、C:0、D:0
		5-6s	A:50％-75％、B:25％-75％、C:0-25％、D:0
6-7s	A:75％-100％、B:50％-75％、C:25％-50％、D:0
		7-8s	A:100％—、B:75％-100％、C:50％-100％、D:0
8-9s	A:100％—、B:100％—、C:75％-100％、D:0-33％
		9-10s	A:100％—、B:100％—、C:100％—、D:33-66％
10-11s	A:100％—、B:100％—、C:100％—、D:66％-100％

In the process that the main control module 130 controls each partition to enter atomization, the distance sensing module continuously detects the distance between the partition and the target object in the configuration direction and judges whether the partition is still in an excessively close state, and if the partition is judged to be in a normal state, the main control module 130 controls each partition to recover to be in a fully transparent state within a second preset time threshold (such as 1s and 2 s), so that misjudgment is prevented. In the above example, at any time during 3-9s, if the distance sensing module senses that the distance parameter is normal (the sensed distance parameter is not less than the preset distance threshold), the main control module 130 further controls the lens to return to the full transparency within 1.5s, and the fog flow process is terminated. It should be clear that the haze variation at different times and in different areas is given only by way of example, and in practical applications, can be adjusted according to the requirements.

In another embodiment, the bad-eye prevention and control parameter sensing module 120 includes a sitting posture sensing module disposed on the main body of the frame or the temple (the first temple or the second temple) for sensing the tilt parameter of the head of the wearer and sending the tilt parameter to the main control module 130. After receiving the inclination parameter, the main control module 130 compares the inclination parameter with a preset inclination threshold, and when the sensed inclination parameter is greater than the preset inclination threshold, it is determined that the PNLC sub-area lens 110 is currently in an improper sitting posture state, and the main control module 130 starts to control each sub-area in the PNLC sub-area lens 110 to enter a fogging state; and when the sensed inclination parameter is not greater than a preset inclination threshold value, judging that the current state is in a normal state. The preset inclination threshold may be set according to actual conditions, such as 15 °, 20 °, or even larger. In an improvement of this embodiment, the main control module 130 includes a timing unit, a duration determining unit and an atomization control unit, in addition to a parameter comparing unit for comparing the sensed tilt parameter with a preset tilt threshold, wherein the timing unit is configured to start timing when the parameter comparing unit determines that the current distance is in the too close state; the duration time judging unit judges whether the duration time of the sitting posture improper state is greater than a first preset time threshold value or not; the atomization control unit is used for respectively controlling each subarea to enter the atomization state according to preset rules when the duration time of the state duration judged by the duration time judging unit is greater than a first preset time threshold, wherein the preset rules comprise the division rule of the independent subareas of the PNLC subarea lens, the sequence of the subareas entering the atomization state under different division rules and the atomization time. The first preset time threshold may be set according to actual conditions, for example, set to 3s, 4s, or even more. The sitting posture sensing module can be a gyroscope, an angle sensor and the like.

The independent lens subareas of the PNLC zones can also be divided according to the actual application requirements, and schemes for realizing the purpose of preventing and controlling bad eyes by randomly adopting a mode of further controlling the atomization state of each zone through the PNLC in the lens after the lens is divided are included in the embodiment, for example, a single lens is divided into an inner ring subarea and a plurality of outer ring subareas (the number of the outer rings can be 0, and the whole lens is taken as the inner ring subarea at this time); for another example, a single lens is divided into four zones, i.e., upper left, upper right, lower left, and lower right, etc. In practical applications, in order to facilitate the wiring of the common terminal shared by the partitions and better accord with human engineering, the single lens can be divided into 1-4 circle partitions, especially into 4 partitions including 1 inner circle partition and 3 outer circle partitions as shown in fig. 2, so as to facilitate the purpose of gradual atomization or gradual transparency from the outer circle to the inner circle. The sequence and time of the atomization state of each subarea can be set according to the actual condition, for example, in one example, a single lens comprises 1 inner ring subarea and 1 outer ring subarea, the atomization is gradually carried out from the outer ring to the inner ring in the atomization process, the inner ring starts to atomize after the outer ring starts to atomize for 2s, and the complete atomization of the inner ring and the outer ring needs 7 s.

In one example, a single lens includes 4 zones as shown in fig. 2 (zone a, zone B, zone C, and zone D from outer to inner). The sitting posture sensing module is a gyroscope, when the gyroscope detects that the head of the wearer inclines for more than 20 degrees and the state lasts for 3s, the wearer is determined to be in an improper sitting posture state (head tilting), the main control module 130 controls the two lenses to gradually change fog from the outer ring to the inner ring at the same time, and the fog is completely changed within 8s (area A), forced reminding is carried out, the haze change corresponding to different time is shown in table 2, wherein Hmax represents peak haze, Eg: Hmax 25% represents 1/4 of the peak haze, namely the haze percentage in the table represents the percentage of the haze peak Hmax.

Table 2: haze change table corresponding to different times in inclination angle induction

In the process that the main control module 130 controls each partition to enter atomization, the sitting posture sensing module continuously detects the inclination parameters of the wearer and judges whether the wearer is still in an improper sitting posture state, and if the wearer is judged to be in the proper sitting posture state, the main control module 130 controls each partition to recover to be completely transparent within a second preset time threshold (such as 1s and 2 s) to prevent misjudgment. In the above example, at any time during 3-11s, if the sitting posture sensing module senses that the tilt parameter is normal (the sensed tilt parameter is not greater than the preset tilt threshold), the main control module 130 further controls the lens to return to the full transparency within 1.5s, and the fog flow process is terminated. It should be clear that the haze variation at different times and in different areas is given only by way of example, and in practical applications, can be adjusted according to the requirements.

In another embodiment, the bad eye prevention and control parameter sensing module 120 includes a distance sensing module and a sitting posture sensing module, and the working principle of the modules is the same as that in the above embodiments, which is not described herein again. The difference is that in the working process, the distance sensing module and the sitting posture sensing module work separately, and when the main control module 130 regulates and controls the lens atomization state according to the distance parameter sensed by the distance sensing module, the relevant functions of sitting posture sensing are shielded; when the main control module 130 adjusts and controls the lens atomization state according to the inclination parameter sensed by the sitting posture sensing module, the distance sensing related function is shielded. That is to say, when the main control module 130 controls the lens atomization state according to the sensing parameter of one of the sensing modules, even if the other sensing module also senses that the lens needs to be controlled to enter the atomization state, the lens is not processed, and after the previous control process is finished, if it is still determined that the lens needs to be controlled to enter the atomization state, the lens is processed.

The embodiment is improved to obtain the present embodiment, in the present embodiment, the intelligent bad-eye prevention and control glasses 100 further includes a glasses leg state induction module 140, which is disposed in the glasses leg (the first glasses leg or the second glasses leg), is connected to the main control module 130, and is used for inducing the opening and closing state of the glasses leg, and the main control module 130 controls the on and off state of the intelligent bad-eye prevention and control function of the glasses according to the opening and closing state of the glasses leg.

In this embodiment, a temple state sensing module 140 configured in the first temple or the second temple is configured to sense whether the temple is in an unfolded state or a folded state, and when it is detected that the temple enters the unfolded state from the folded state, the glasses intelligent bad-use eye prevention and control function is turned on, that is, the glasses intelligent bad-use eye prevention and control function enters a starting state; when the glasses are detected to enter the folding state from the unfolding state, the intelligent bad eye using prevention and control function of the glasses is closed, namely the glasses enter the shutdown state. Here, the temple state sensing module 140 may have various types, for example, one or more types of hall sensors, gyroscopes, angle sensors (sensing angle change data), etc., and may determine the open/close state of the temple by sensing data related to the temple. In one example, the temple state sensing module 140 is a hall sensor, and for sensing, the hall sensor may be disposed on one temple, and the magnet may be disposed on the other temple, so that when the first temple and the second temple are in the folded state, the hall sensor and the magnet are closer to each other, and the sensed magnetic field strength is larger (larger than the preset magnetic field strength threshold); when the first glasses leg and the second glasses leg are in the unfolding state, the distance between the Hall sensor and the magnet is long, and the induced magnetic field strength is small (not larger than a preset magnetic field strength threshold), so that the opening and closing state of the glasses legs is determined according to the magnetic field strength induced by the Hall sensor.

In order to improve user experience, an indicator light module for turning on and off the glasses may be further configured on the glasses, for example, when the main control module 130 controls to enter the power-on state, the indicator light module is turned on for a certain time (e.g., 2s, 5s, etc.) and then automatically turned off, so as to prompt the user to enter the power-on state. In one example, the Hall sensor is arranged in the glasses leg, and when the glasses leg is detected to be in the unfolding state, the glasses leg automatically enters the starting state; when the temple is detected to be in the folded state, the temple automatically enters the power-off state. And after the power-on is detected, the indicator light on the side of the glasses leg is turned on for 5s and then automatically turned off to prompt the user that the power-on is finished.

In this embodiment, the intelligent glasses for controlling bad eyes 100 further includes a wearing state sensing module 150, which is disposed inside the frame main body or the temple (the first temple or the second temple), connected to the main control module 130, and configured to sense a wearing state of the glasses and send the sensing state to the main control module 130, and the main control module 130 controls a working state of the intelligent glasses for controlling bad eyes according to the wearing state of the glasses.

In practical applications, the wearing state sensing module 150 may be an infrared sensor, and when the user wears the glasses, the infrared sensor receives reflected infrared light, so as to realize intelligent detection of the wearing state of the glasses. In other examples, the wearing state sensing module 150 may also be other sensing modules, such as a gravity sensing module (for achieving the purpose by sensing the change of the gravitational acceleration), and the like, which is not specifically limited herein, as long as the purpose of the utility model can be achieved.

In the power-on state, if the wearing state sensing module 150 detects that the user wears glasses, the state is in a "working" state, and the main control module 130 controls the bad eye protection and control parameter sensing module 120 to start working; when the user is detected to take off the glasses, the glasses enter a standby state, and the main control module 130 controls the bad eye prevention and control parameter induction module 120 to start entering a sleep state, so that the working state of the whole system is intelligently controlled.

In the above embodiment, in order to improve the detection accuracy and prevent the erroneous determination, when the wearing state sensing module 150 detects that the user takes off the glasses, the main control module 130 controls the bad eye prevention and control parameter sensing module 120 to start entering the sleep state after a preset time (e.g., 1s, 2s, etc.) is reached. In one example, in a startup state, if it is detected that a user wears glasses, the user automatically enters a 'working' state; and when the situation that the user takes off the glasses is monitored, the system enters a standby state after 1s, and the system enters a dormant state.

The position of the loudspeaker in the first mirror leg and/or the second mirror leg can be adjusted according to actual conditions, and the loudspeaker is close to the ear of a user, so that the user can receive a file played by the user conveniently. In order to save resources, when it is detected that the user takes off the glasses, the main control module 130 controls the speaker module 160 to stop playing. The wireless communication module 170 is used for data interaction with the outside, and includes receiving control information, uploading induction parameters and the like, and may be a wifi module, a bluetooth module, an infrared module and the like.

In one example, the wireless communication module is a bluetooth module, and the speaker module 160 is used to implement the function of a bluetooth headset, and the transmission of multimedia files and call voice. This bluetooth module can carry out mutual independent ordinary connection or pass through APP between the external intelligent terminal and be connected, and wherein, ordinary connection is applied to user (child) daily listen to music, online class, answer a call and use, if with intelligent terminal such as the learning that disposes bluetooth module equally be connected.

After the power module is started, if the power module is less than a preset low-power threshold (such as 20% or 25% of full power), red color is displayed, and if the power module exceeds the preset low-power threshold, green color is displayed. When the battery capacity is left with a preset low electric quantity threshold value and a preset minimum electric quantity threshold value (such as 5% of full electric quantity), low electric quantity reminding is respectively carried out, a low electric quantity reminding sound effect is sent out through the loudspeaker module 160, the low electric mode is entered, the electric quantity indicator lamp is controlled to turn red and flash, the flashing period and the duration can be set according to the actual situation, and the flashing period and duration can be set according to the actual situation, for example, the flashing period is 3s with 200ms as the period.

When charging, the glasses legs are put in the glasses case 200, the power supply battery supplies power for the power module in the glasses, and the charging purpose can be achieved in a mode of configuring the matching interface. When the power supply battery is not charged, the power supply battery is charged through a charging interface (e.g., Type-C interface) disposed at the back of the glasses case 200.

The second power display module of the glasses case 200 is similar to the first power display module of the glasses, and is used for displaying the power of the power supply battery. The specific form of the second electric quantity display module can be set according to actual requirements, for example, a liquid crystal display module is arranged in each glasses leg, and the electric quantity of the battery is displayed in real time; and if the power supply is provided with a plurality of indicator lamps with different colors, different electric quantities are prompted.

In order to improve the accuracy of the usage duration statistics, if the user stops wearing (takes off the glasses) and the time exceeds a preset time (such as 3min, 5min and the like) within the set duration, the user again wears the glasses and counts the time again. For time statistics, the statistical rules can be set according to actual conditions, for example, in an example, the time statistics is not affected by standby, shutdown and the like, that is, the shutdown and standby cannot reset the time statistics; the time indicator lamp is in an off state when being turned off, and is kept in a normally-on state in a standby state and a working state; when the user does not wear the glasses for 8 consecutive hours, the time statistics are reset, etc.

The utility model also provides an intelligent bad eye prevention and control glasses control method, which is applied to the intelligent bad eye prevention and control glasses, and as shown in fig. 7, the intelligent bad eye prevention and control glasses control method comprises the following steps: s10, acquiring the bad eye prevention and control parameters sensed by the bad eye prevention and control parameter sensing module, wherein the bad eye prevention and control parameter sensing module is configured on the spectacle frame main body or the spectacle legs; s20 controls the fogging status of each zone in the PNLC zone lens according to the defective eye prevention and control parameter, and the PNLC zone lens is disposed on the frame body.

The step of obtaining the bad eye prevention and control parameters sensed by the bad eye prevention and control parameter sensing module comprises the following steps: sensing a distance parameter between the target object and the configuration direction and/or sensing a tilt parameter of the head of the wearer; the control of the fogging state of each zone in the PNLC zone lens according to the bad eye prevention and control parameters comprises the following steps: and controlling the atomization state of each zone in the PNLC zone lens according to the distance parameter sensed by the distance sensing module and/or the inclination parameter sensed by the sitting posture sensing module.

The preset distance threshold may be set according to actual conditions, such as 20cm, 30cm, and the like, or even further. The first preset time threshold may be set according to actual conditions, such as 3s, 4s, and so on. The independent lens subareas of the PNLC zones can be divided according to actual application requirements, and schemes for realizing the purpose of preventing and controlling bad eyes by randomly adopting a mode of further controlling the atomization state of each zone through the PNLC in the lens after the lens is divided are included in the embodiment, for example, a single lens is divided into an inner ring subarea and a plurality of outer ring subareas (the number of the outer rings can be 0, and the whole lens is taken as the inner ring subarea at this time); for another example, a single lens is divided into four zones, i.e., upper left, upper right, lower left, and lower right, etc. In practical applications, in order to facilitate the wiring of the common terminal shared by the partitions and better accord with human engineering, the single lens can be divided into 1-4 circle partitions, especially into 4 partitions including 1 inner circle partition and 3 outer circle partitions as shown in fig. 2, so as to facilitate the purpose of gradual atomization or gradual transparency from the outer circle to the inner circle. The sequence and time of the atomization state of each subarea can be set according to the actual situation, for example, in one example, a single lens comprises 1 inner circle subarea and 2 outer circle subareas, and atomization is carried out from the outer circle to the inner circle step by step in the atomization process; for another example, in another example, a single lens includes 1 inner ring subarea and 1 outer ring subarea, and during the atomization process, the inner ring subarea and the outer ring subarea synchronously enter the atomization state, and the like. In practical application, the distance sensing module is a distance sensor and can be arranged at the middle position of the spectacle frame main body, namely the middle position of the two lenses above the nose pad, so as to improve the accuracy of sensing data.

In another embodiment, the controlling the fogging status of each zone in the PNLC zone lens according to the tilt parameter sensed by the sitting posture sensing module comprises: judging whether the inclination parameter sensed by the sitting posture sensing module is larger than a preset inclination threshold value or not; if so, judging that the current sitting posture is in an improper state; judging whether the duration time of the sitting posture improper state is greater than a first preset time threshold value or not; if yes, respectively controlling each subarea to enter the atomizing state according to preset rules, wherein the preset rules comprise the division rule of the independent subareas of the PNLC subarea lens, the sequence of the subareas entering the atomizing state under different division rules and the atomizing time. The independent lens subareas of the PNLC zones can also be divided according to the actual application requirements, and schemes for realizing the purpose of preventing and controlling bad eyes by randomly adopting a mode of further controlling the atomization state of each zone through the PNLC in the lens after the lens is divided are included in the embodiment, for example, a single lens is divided into an inner ring subarea and a plurality of outer ring subareas (the number of the outer rings can be 0, and the whole lens is taken as the inner ring subarea at this time); for another example, a single lens is divided into four zones, i.e., upper left, upper right, lower left, and lower right, etc. In practical applications, in order to facilitate the wiring of the common terminal shared by the partitions and better accord with human engineering, the single lens can be divided into 1-4 circle partitions, especially into 4 partitions including 1 inner circle partition and 3 outer circle partitions as shown in fig. 2, so as to facilitate the purpose of gradual atomization or gradual transparency from the outer circle to the inner circle. The sequence and time of the atomization state of each subarea can be set according to the actual condition, for example, in one example, a single lens comprises 1 inner ring subarea and 1 outer ring subarea, the atomization is gradually carried out from the outer ring to the inner ring in the atomization process, the inner ring starts to atomize after the outer ring starts to atomize for 2s, and the complete atomization of the inner ring and the outer ring needs 7 s. The preset inclination threshold may be set according to actual conditions, such as 15 °, 20 °, or even larger. The first preset time threshold may be set according to actual conditions, such as 3s, 4s, and so on. In practical application, the sitting posture sensing module can be a gyroscope, an angle sensor and the like.

Here, the temple state sensing module may be various, for example, one or more of a hall sensor, a gyroscope, an angle sensor (sensing angle change data), and the like, and determines the open/close state of the temple by sensing data related to the temple. In one example, the glasses leg state sensing module is a hall sensor, in order to achieve the sensing purpose, the hall sensor may be arranged on one of the glasses legs, and the magnet may be arranged on the other glasses leg, so that when the first glasses leg and the second glasses leg are in the folded state, the distance between the hall sensor and the magnet is relatively short, and the sensed magnetic field strength is relatively large (greater than a preset magnetic field strength threshold); when the first glasses leg and the second glasses leg are in the unfolding state, the distance between the Hall sensor and the magnet is long, and the induced magnetic field strength is small (not larger than a preset magnetic field strength threshold), so that the opening and closing state of the glasses legs is determined according to the magnetic field strength induced by the Hall sensor.
