The intelligent wearable device 100 provided in the embodiments of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

As shown in fig. 1 to 4, the smart wearable device 100 according to the embodiment of the present invention includes: device body 10, lens 20, piezoelectric element and power source 40.

Specifically, the apparatus body 10 is provided with an installation space, the lens 20 is provided in the installation space and fixed by the apparatus body 10, the piezoelectric element is provided in the apparatus body 10, the piezoelectric element generates ultrasonic vibration in a power-on state to clean the lens 20, the power supply 40 is provided in the apparatus body 10, and the power supply 40 supplies power to the piezoelectric element.

In other words, the smart wearable device 100 according to the embodiment of the present invention is mainly composed of a device body 10 having an installation space, a lens 20 provided in the installation space, a piezoelectric element capable of performing ultrasonic vibration cleaning on the lens 20, and a power supply 40 supplying power to the piezoelectric element. The lens 20 can be fixed in the installation space by the device body 10, the piezoelectric element is arranged on the device body 10, and when the piezoelectric element is electrified, the control system can output voltages with different magnitudes or different directions, so that ultrasonic vibration is generated, and dirt on the lens 20 is removed.

It should be noted that the smart wearable device 100 in the present application may be an electronic device suitable for wearing, such as a watch, a bracelet, or glasses. The piezoelectric element includes, but is not limited to, piezoelectric ceramics, and may be other existing piezoelectric materials. The environment in which the piezoelectric element is used may be a liquid environment or an air environment. When the apparatus body 10 is in a liquid environment, the power source 40 is turned on, the piezoelectric element is in an energized state, and when a high-frequency electric signal is applied to the piezoelectric element, a high-frequency acoustic signal (mechanical vibration) is generated. Ultrasonic waves emitted by the piezoelectric element act on liquid, and the breakage of each bubble in the liquid can generate shock waves with great capacity, so that the inner and outer surfaces of the components such as the lens 20 are cleaned and washed. When the apparatus body 10 is located in an air environment, the piezoelectric element in the energized state applies ultrasonic vibration waves (mechanical waves) to the apparatus body 10 or directly to the lens 20, and the stains such as fine powder attached to the lens 20 receive a large ultrasonic acceleration, thereby suppressing the adhesion of stains, and the stains are easily released from the lens 20.

Therefore, according to the intelligent wearable device 100 of the embodiment of the invention, the piezoelectric element is arranged on the device body 10, the piezoelectric element can clean the lens 20 at any time and any place when the device is powered on, and even if a user wears the intelligent wearable device 100 on the body, the lens 20 can be cleaned in time. This intelligence wearing equipment 100 can clean lens 20 through control ultrasonic wave vibrations ripples, and easy operation is feasible, has avoided current wearing equipment to carry out clear problem after need taking off, need not water also can wash, prevents to wash and damages intelligent electronic system, and the convenience is promoted by a wide margin, and is clean effectual.

According to one embodiment of the present invention, the apparatus body 10 is a spectacle frame, and the piezoelectric element includes: the lens comprises a piezoelectric crystal 31 and a positive electrode 32 and a negative electrode 33, wherein the piezoelectric crystal 31 is filled in at least one part of the glasses frame, the positive electrode 32 and the negative electrode 33 are arranged in the glasses frame in a spaced mode, and the positive electrode 32 and the negative electrode 33 are electrified with a power supply 40 to generate internal stress or opposite internal stress on the piezoelectric crystal 31.

In other words, the positive pole of power source 40 is electrically connected to piezoelectric crystal 31 through the positive electrode access of positive electrode 32, and the negative pole of power source 40 is electrically connected to piezoelectric crystal 31 through the negative electrode access of negative electrode 33. As shown in fig. 3 and 4, after the voltage is applied, the electric charges in the piezoelectric crystal 31 between the positive electrode 32 and the negative electrode 33 are rearranged. In addition, when a voltage (e.g., a forward voltage) is input, the positive electrode 32 and the negative electrode 33 of the piezoelectric crystal 31 are energized, and the piezoelectric crystal 31 between the positive electrode 32 and the negative electrode 33 generates an internal stress due to a bipolar charge action, and the direction of the internal stress is shown by two upper and lower arrows in fig. 4. When a reverse voltage is input, the piezoelectric crystal 31 generates internal stress in the opposite direction.

Specifically, when an external voltage is applied to piezoelectric crystal 31, the centers of the positive and negative charges in piezoelectric crystal 31 attract or repel each other, causing piezoelectric crystal 31 to expand or contract. When a voltage is applied to the polarization direction of the piezoelectric crystal 31, the piezoelectric crystal 31 will deform in the longitudinal direction, and the magnitude of the deformation is positively correlated with the magnitude of the applied electric field, i.e. by applying different voltages, the ultrasonic vibrations with different frequencies can be generated to clean the lens 20. When the applied electric field is an alternating electric field, the deformation of the piezoelectric crystal 31 changes with the change of the electric field, and the change is consistent with the change of the electric field.

Optionally, a part of the eyeglass frame is a hollow structure, and the piezoelectric crystal 31 is filled in the hollow part of the eyeglass frame. By providing a portion of the eyeglass frame as a hollow structure, it is advantageous to mount the piezoelectric crystal 31, avoiding the piezoelectric crystal 31 from being exposed to the outer surface of the eyeglass frame.

Optionally, the spectacle frame is a hollow structure as a whole, and the piezoelectric crystal 31 is filled in the spectacle frame extending along the circumferential direction of the lens 20. That is, the entire structure of the eyeglass frame may be a hollow structure, the installation space may be provided within the hollow structure, and the piezoelectric crystal 31 may be filled between the lens and the eyeglass frame. It should be noted that, compared to the embodiment in which a part of the glasses frame is configured as a hollow structure, the present embodiment facilitates the installation of the piezoelectric crystal 31 by configuring the whole structure of the glasses frame as a hollow structure and installing the piezoelectric crystal 31 in the hollow structure, thereby preventing the piezoelectric crystal 31 from affecting the sight range of the user. And set up piezoelectric crystal 31 around the round of lens 20, be in under operating condition at piezoelectric crystal 31, be favorable to transmitting vibration energy to lens 20 to play better clean effect to lens 20, and can clean the linking position between lens 20 and the spectacle-frame, prevent that the dust from blockking up the linking position.

In some embodiments of the invention, positive electrode 32 and negative electrode 33 are disposed at opposite ends of lens 20.

Specifically, two lenses 20 are usually mounted on the glasses frame, and one electrode may be respectively disposed at the left and right ends of each lens 20, that is, one positive electrode 32 is disposed at one end of one lens 20, and the other negative electrode 33 is disposed at the other end, or one electrode may be respectively disposed at the left and right ends of the whole glasses frame, that is, one positive electrode 32 is disposed at one end of the glasses frame, and the other negative electrode 33 is disposed at the other end of the glasses frame. The specific installation number of the electrodes can be reasonably adjusted according to the size of a glasses frame or other actual use requirements, and the positive electrodes 32 and the negative electrodes 33 are arranged at the two ends of the lens 20, so that the stress uniformity of the lens 20 can be improved, and the cleaning area is enlarged.

According to an embodiment of the present invention, the smart wearable device 100 further includes a photosensitive sensor 50, the photosensitive sensor 50 is disposed on the lens 20 to detect the light transmittance of the lens 20, and the positive electrode 32 and the negative electrode 33 of the photosensitive sensor 50 are powered on the power source 40 under the condition that the light transmittance of the lens 20 is lower than a standard value.

That is, the photosensitive sensor 50 is provided on the lens 20, and the light transmittance of the lens 20 can be monitored in real time by the photosensitive sensor 50. When the lens 20 is dirty, the light transmittance of the lens 20 is reduced due to the light blocking by the dirt, the photosensitive sensor 50 detects and sends an indication to the central controller 60, and outputs a voltage to the positive electrode 32 and the negative electrode 33 of the piezoelectric crystal 31, and the voltage can be changed continuously to generate ultrasonic vibration, so that the lens 20 can be automatically cleaned.

In addition, the transmittance of the cleaning lens can be set to a standard value, which can be a normal state value without contamination of the lens, and as a reference, when the transmittance detected by the photosensitive sensor 50 is lower than the standard value, the cleaning procedure is automatically started.

Optionally, the photosensitive sensor 50 is disposed on the outer periphery of one side of the lens 20, so as to detect the transmittance of light while avoiding interference with the sight range of the user.

In some embodiments of the present invention, the smart wearable device 100 further includes a cleaning switch disposed on the device body 10, and the cleaning switch can turn on and off the connection between the power source 40 and the positive electrode 32 and the negative electrode 33. That is to say, the user can also open or close the cleaning process by hand, promotes the use experience.

Preferably, the smart wearable device 100 further comprises an oleophobic and dust-repellent film 70, wherein the oleophobic and dust-repellent film 70 is disposed on at least one side of the lens 20. Further, the oleophobic and dust-repellent film 70 is a hydrophobic and oleophobic nanostructure.

It is noted that the liquid wettability of the solid surface is usually measured by a contact angle, and the contact angles of the solid surface of the hydrophobic and oleophobic nanostructure to water and oil are both larger than 90 degrees. The amphiphobic material can greatly reduce the free energy of the surface, can obviously reduce the surface tension, can form spherical liquid drops under the surface tension of water and oil drops when the water and the oil drops are on the lens 20, and can achieve the automatic cleaning effect under the ultrasonic vibration.

When the oleophobic and dust-repellent film 70 covers the inner side and the outer side of the lens 20, after dust or oil dirt is adhered to the lens 20, the amphiphobic material can greatly reduce the free energy of the surface, the surface tension is obviously reduced, and the oil dirt and the dirt are automatically gathered into spherical liquid drops so as to be easily removed under the vibration of ultrasonic waves and avoid water washing.

According to one embodiment of the invention, the thickness of the piezoelectric element is equal to the combined thickness of the lens 20 and the oleophobic dust-shedding membrane 70. When the thickness of the piezoelectric element is equal to the total thickness of the lens 20 and the oleophobic and dust-repellent film 70, a gap can be avoided from occurring at the joint part of the spectacle frame and the lens 20 and the piezoelectric element, so that the spectacle frame is not easy to deform, and the piezoelectric element is not easy to displace.

The workflow of the intelligent wearable device 100 according to the embodiment of the present invention is described in detail below with reference to fig. 5.

S1, monitoring the transmittance of the lens 20 through the light sensitive sensor 50.

S2, when the transmittance of the lens 20 is lower than the standard value, the photosensitive sensor 50 sends an indication to the central controller 60.

S3, the central controller 60 controls the power source 40 to output voltage to the positive electrode 32 and the negative electrode 33 on both sides of the piezoelectric crystal 31, and the voltage can be changed continuously.

And S4, converting the electric energy into mechanical energy, and generating ultrasonic vibration by the piezoelectric crystal 31 to clean the lens 20.

S5, monitoring the light transmittance through the photosensitive sensor 50, judging the magnitude relation between the light transmittance and the standard value, stopping cleaning if the light transmittance is not lower than the standard value, and returning to the step S2 if the light transmittance is still lower than the standard value.

In other words, in the on state of the smart wearable device 100, firstly, the light transmittance of the lens 20 is monitored by the light-sensitive sensor 50 in real time or at regular time, and when the light transmittance of the lens 20 meets the set standard value, the light-sensitive sensor 50 may not give an indication or give an indication that the lens 20 is normal.

When the light transmittance is affected by the dirt on the lens 20, the photosensitive sensor 50 can detect that the light transmittance of the lens 20 is lower than a standard value, and then send a clean indication that the lens 20 is dirty to the central controller 60.

After the central controller 60 receives the cleaning indication of the photosensitive sensor 50, the central controller 60 controls the power source 40 to output a voltage to the positive electrode 32 and the negative electrode 33 on both sides of the piezoelectric crystal 31, wherein the voltage can change in magnitude or direction continuously.

The piezoelectric crystal 31 converts the electric energy into mechanical energy according to the change of the voltage, and generates ultrasonic vibration to clean the lens 20.

The photosensitive sensor 50 continuously monitors the light transmittance of the lens 20, judges the magnitude relation between the light transmittance and a standard value, and if the light transmittance reaches or is higher than the set standard value, an instruction of stopping cleaning is sent to the central controller 60, the central controller 60 controls the power supply 40 to cut off the power supply to the piezoelectric crystal 31, and the piezoelectric element stops cleaning; if the transmittance is still lower than the standard value, the process returns to step S2 to continue cleaning the lens 20.

In summary, the intelligent wearable device 100 according to the embodiment of the present invention can clean the lens 20 by ultrasonic vibration in the power-on state by installing the piezoelectric element on the device body 10, and can be cleaned without water, thereby preventing the intelligent electronic system from being damaged by water washing. Still cooperate with piezoelectric element through photosensitive sensor 50, when the luminousness of lens 20 is less than the standard value, carry out automatically cleaning to lens 20, realize the automatic lens that washs, can wash according to actual conditions often. In addition, still through setting up oleophobic and dredged dirt membrane 70, when inhibiting the spot adhesion, promote ultrasonic vibration cleaning effect and clean efficiency.
