Description

Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to a smart pair of glasses. Background Technology

[0002] With the development of science and technology and the improvement of people's living standards, eyeglasses are being used more and more widely in people's daily lives. Eyeglasses can be used to correct vision, and they can also be used to help people watch 3D (Three-Dimensional) movies and improve the viewing experience, etc.

[0003] In existing technology, eyeglasses typically have nose pads and temples as support structures for ease of wear. However, wearing eyeglasses for extended periods can easily lead to the nose pads pressing on the bridge of the nose and the temples pressing on the earlobes, causing soreness, discomfort, fatigue, and poor comfort. Summary of the Invention

[0004] In view of the above problems, the present invention is proposed to provide a smart glasses that overcomes or at least partially solves the above problems.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] This application provides an embodiment of smart glasses, which includes: a frame, temples, and nose pads. Both the temples and nose pads are connected to the frame, and at least one of the temples and nose pads is equipped with a massage component.

[0007] The massage assembly includes a pressure sensor and an electrodeformable element. The pressure sensor is connected to at least one of the temple and the nose pad, and the pressure sensor is used to detect the pressure value of at least one of the temple and the nose pad.

[0008] The electro-deformable element expands and contracts at a preset frequency based on the pressure value.

[0009] In this embodiment, when the nose pad is equipped with a massage component, a pressure sensor detects the pressure value of the nose pad, which also represents the pressure on the bridge of the nose. An electro-deformable element can expand and contract based on this pressure value, causing the nose pad to massage the bridge of the nose at a preset frequency, thus relieving discomfort and fatigue caused by pressure from the nose pad. When the temples are equipped with a massage component, a pressure sensor detects the pressure value of the temples, which also represents the pressure on the auricle. The electro-deformable element can expand and contract based on this pressure value, causing the temples to massage the auricle, such as the temples, at a preset frequency, relieving discomfort and fatigue caused by pressure from the temples. When both the nose pad and temples are equipped with massage components, the pressure sensor can simultaneously detect the pressure on both the nose pad and temples, allowing the nose pad to massage the bridge of the nose while the temples massage the auricle, further alleviating soreness and discomfort caused by prolonged wear of smart glasses and improving user comfort.

[0021] Reference Figure 1 This diagram illustrates the structure of a smart glasses embodiment according to this application, specifically including: a frame 10, temples 20, and nose pads 30. Both temples 20 and nose pads 30 are connected to the frame 10, and at least one of the temples 20 and nose pads 30 is equipped with a massage component.

[0022] The massage assembly includes a pressure sensor 11 and an electrodeformable element 12. The pressure sensor 11 is connected to at least one of the temple 20 and the nose pad 30. The pressure sensor 11 is used to detect the pressure value of at least one of the temple 20 and the nose pad 30.

[0023] The electro-deformable element 12 expands and contracts at a preset frequency based on the pressure value.

[0024] In this embodiment, when the nose pad 30 is equipped with a massage component, the pressure sensor 11 detects the pressure value of the nose pad 30, which also represents the pressure on the bridge of the nose. The electro-deformable element 12 can expand and contract based on the pressure value of the nose pad 30, so that the nose pad 30 massages the bridge of the nose at a preset frequency to relieve discomfort caused by the pressure of the nose pad 30 and alleviate fatigue. When the temple 20 is equipped with a massage component, the pressure sensor 11 detects the pressure value of the temple 20, which also represents the pressure on the auricle. The electro-deformable element 12 can expand and contract based on the pressure value, so that the temple 20 massages the auricle, such as the temples, at a preset frequency to relieve discomfort caused by the pressure of the temple 20 around the auricle and alleviate fatigue. With massage components provided on both the temples 20 and the nose pads 30, the pressure sensor 11 can simultaneously detect the pressure on the temples 20 and the nose pads 30, so that while the nose pads 30 massage the bridge of the nose, the temples 20 also massage the area around the ears, further relieving the soreness and discomfort caused by wearing smart glasses for a long time and improving the user's comfort when wearing smart glasses.

[0025] In this way, without affecting the normal function of the glasses, such as vision correction and assisting in watching 3D movies, the smart glasses can have a massage function, thus improving the user experience.

[0026] In this embodiment, the electrodeformable element 12 exhibits an electrostrictive effect. Specifically, the electrostrictive effect refers to the spontaneous formation of molecular clusters, i.e., electric domains, within the electrodeformable element 12. These electric domains are capable of polarization, causing changes in the length of the electrodeformable element 12 along the polarization direction, thereby achieving expansion and contraction. Under the action of an applied electric field, the polarization direction of the electric domains is the same as the direction of the external electric field. Therefore, the direction of expansion and contraction of the electrodeformable element 12 can be controlled by controlling the direction of the applied electric field.

[0027] For example, in the embodiments of this application, the material of the electrodeformable element 12 includes polycrystalline materials, such as lead zirconate titanate ceramics, ferroelectric polymers, etc. The specific material of the electrodeformable element 12 is not limited in the embodiments of this application.

[0028] Specifically, in this embodiment, the pressure sensor 11 is provided with a preset pressure value. When the pressure value of the pressure sensor 11 is less than the preset pressure value, the electro-deformable element 12 can increase the extension range. When the pressure value of the pressure sensor 11 is greater than the preset pressure value, the electro-deformable element 12 can decrease the extension range, so that the electro-deformable element 42 extends and retracts at an appropriate range, thereby realizing the real-time detection of the extension range of the electro-deformable element 12 by the pressure sensor 11, so as to achieve a better massage effect for the user.

[0029] In this embodiment, the preset frequency can be pre-set according to user needs to achieve a better massage effect, such as 50 times per minute, 60 times per minute, etc. This embodiment does not limit the specific value of the preset frequency. In this embodiment, the amplitude and frequency can be adjusted appropriately according to the different needs of different users, thus meeting personalized user requirements and improving the user experience.

[0030] Specifically, in this embodiment, the temple 20 and nose pad 30 can be made of insulating material. The electrodeformable element 12 is disposed within the nose pad 30 and / or temple 20 to prevent leakage of current when the electrodeformable element 12 is working, thus preventing safety accidents. For example, the temple 20 can be made of plastic, resin, or other materials, and the nose pad 30 can also be made of plastic, resin, or other materials. The materials of the temple 20 and nose pad 30 can be the same or different. This embodiment does not limit the specific materials used for the temple 20 and nose pad 30.

[0031] Optionally, in this embodiment, the smart glasses further include a voltage controller 13, which is electrically connected to both the pressure sensor 11 and the electrodeformable element 12. The voltage controller 13 outputs a first voltage to the electrodeformable element 12 based on the pressure value, thereby controlling the electrodeformable element 12 to extend and retract at a preset frequency. The first voltage is inversely proportional to the pressure value, and the preset frequency is directly proportional to the first voltage.

[0032] A first voltage is applied to the electrostrictive element 12 by the voltage controller 13 to form an electric field, causing the electrostrictive element 12 to expand and contract at a preset frequency. Specifically, when the pressure value of the pressure sensor 11 decreases to less than the preset pressure value, the voltage controller 13 increases the first voltage, so that the electrostrictive element 12 can expand and contract at a greater amplitude and at a greater preset frequency according to the increased first voltage. When the pressure value of the pressure sensor 11 increases to greater than the preset pressure value, the voltage controller 13 decreases the first voltage, so that the electrostrictive element 12 can contract and contract at a lesser amplitude and at a preset frequency according to the decreased first voltage. In this way, the electrostrictive element 42 can expand and contract at an appropriate amplitude and frequency to precisely control the massage effect required by the user.

[0033] In some alternative embodiments of this application, such as Figure 2 As shown, both the temples 20 and the nose pads 30 include a first end 14 close to the body and a second end 15 away from the body. The direction from the first end 14 to the second end 15 is a first direction A. The first voltage controls the electro-deformable element 12 to extend and retract along the first direction A at the preset frequency. This allows the electro-deformable element 12 to extend and retract from the first end 14 close to the body to the second end 15 away from the body, preventing the electro-deformable element 12 from extending and retracting in a direction where the massage function cannot be achieved, thereby improving the massage effect on the bridge of the nose and / or the area around the ears.

[0034] In this embodiment, the massage component further includes a first electrode 21 and a second electrode 22, both connected to a voltage controller 13. The first electrode 21 and the second electrode 22 are connected to both ends of the electrodeformable element 12 along a first direction A, causing the electrodeformable element 12 to extend and retract along the first direction A. Thus, the first electrode 21 and the second electrode 22 generate an electric field along the first direction A, enabling the electrodeformable element 12 to extend and retract from a first end 14 near the human body to a second end 15 away from the human body, achieving a massage effect.

[0035] In some alternative embodiments of this application, such as Figure 3 As shown, the massage component may include a plurality of first electrodes 21 and a plurality of second electrodes 22. The plurality of first electrodes 21 are spaced apart on the massage component and connected in parallel; the plurality of second electrodes 22 are also spaced apart on the massage component and connected in parallel; wherein one first electrode 21 corresponds to one second electrode 22. In this way, an electric field can be formed in multiple areas of the massage component where the first electrodes 21 and second electrodes 22 are located, causing the electrodynamic deformable element 12 to extend and retract at multiple positions along a first end 14 close to the human body to a second end 15 away from the human body, thereby enhancing the massage effect of the smart glasses and improving the user experience.

[0036] Specifically, of the first electrode 21 and the second electrode 22, one is a positive electrode and the other is a negative electrode, so that an electric field is formed between the first electrode 21 and the second electrode 22. In the embodiments of this application, the first electrode 21 can be set as the positive electrode and the second electrode 22 as the negative electrode, or the first electrode 21 can be set as the negative electrode and the second electrode 22 as the positive electrode. The specific configuration of the first electrode 21 and the second electrode 22 is not limited in the embodiments of this application.

[0037] Optionally, in this embodiment, when the massage component is disposed on the temple 20, the pressure sensor 11 is also used to detect the leg pressure of the temple 20, and the voltage controller 13 outputs a second voltage to the electrodeformable element 12 based on the leg pressure. The second voltage controls the electrodeformable element 12 to extend and retract along the second direction B to adjust the tightness of the smart glasses. The second direction B is perpendicular to the first direction A.

[0038] During actual wear of smart glasses, the temples 20 are typically closely related to the comfort of the fit. By controlling the electro-deformable element 12 to extend and retract along a second direction B perpendicular to the first direction A via the second voltage, the axial length of the temples 20 can be adjusted, thereby regulating the comfort of the smart glasses. This is automatic, simple, and convenient, avoiding the inability to easily restore the glasses to a suitable tightness when they deform due to prolonged wear or external force. Furthermore, it can adjust the smart glasses to a suitable tightness according to different users, enhancing user personalization. In addition, if the position where the electro-deformable element 12 stops extending and retracting changes from its initial position when the user stops the massage function, the tightness of the smart glasses can also be restored by adjusting the axial length of the temples 20, further improving the user experience.

[0039] In practical applications, a preset leg pressure can be set. When the pressure sensor 11 detects that the leg pressure of the temple 20 is less than the preset leg pressure, the voltage controller 13 increases the second voltage to make the electrodeformable element 12 extend along the second direction B. When the pressure sensor 11 detects that the leg pressure of the temple 20 is greater than the preset leg pressure, the voltage controller 13 decreases the second voltage to make the electrodeformable element 12 shorten along the second direction B until the leg pressure detected by the pressure sensor 11 is within the preset leg pressure range, so as to adjust the tightness of the smart glasses to a suitable degree.

[0040] Specifically, in the embodiments of this application, such as Figure 2As shown, the massage assembly also includes a third electrode 23 and a fourth electrode 24. Along the second direction B, the third electrode 23 and the fourth electrode 24 are respectively connected to both ends of the electrodeformable element 12, allowing the electrodeformable element 12 to extend and retract along the second direction B. In this way, the third electrode 23 and the fourth electrode 24 generate an electric field along the second direction B, enabling the electrodeformable element 12 to extend and retract along the second direction B, which is perpendicular to the first direction A, thus achieving the function of adjusting tightness.

[0041] Optionally, in this embodiment, the number of third electrodes 23 may include multiples, and the number of fourth electrodes 24 may also include multiples. Multiple third electrodes 23 are spaced apart on the massage component and connected in parallel; multiple fourth electrodes 24 are spaced apart on the massage component and connected in parallel; wherein one third electrode 23 corresponds to one fourth electrode 24. In this way, an electric field can be formed in multiple areas on the massage component where the third electrodes 23 and fourth electrodes 24 are provided, causing the electrodeformable element 12 to extend and retract at multiple positions along the second direction B, enhancing the extension and retraction range of the smart glasses and improving adjustment efficiency.

[0042] In this embodiment, similarly, one of the third electrode 23 and the fourth electrode 24 is a positive electrode and the other is a negative electrode, so that an electric field is formed between the third electrode 23 and the fourth electrode 24. For example, the third electrode 23 can be set as the positive electrode and the fourth electrode 24 as the negative electrode, or the third electrode 23 can be set as the negative electrode and the fourth electrode 24 as the positive electrode. The specific configuration of the third electrode 23 and the fourth electrode 24 is not limited in this embodiment.

[0043] Specifically, in this embodiment, the first voltage includes an alternating current (AC) voltage, and the second voltage includes a direct current (DC) voltage. By applying the AC voltage to the electrodeformable element 12, the electrodeformable element 12 can reciprocate and extend in the first direction A, thereby achieving a better massage effect. By applying the DC voltage to the electrodeformable element 12, the electrodeformable element 12 can extend or contract in the second direction B until the pressure sensor 11 detects that the leg pressure is a preset suitable leg pressure. Then, the output of the second voltage stops, stabilizing the size of the electrodeformable element 12, so that the smart glasses are adjusted to a suitable tightness.

[0044] Optionally, in the embodiments of this application, such as Figure 1 and Figure 4As shown, the smart glasses also include temples 40 connected to the temples 20. An adjustment assembly is provided within the temples 40, comprising a pressure detector 41 and an electrostrictive element 42. The pressure detector 41 is connected to the temples 40 and is used to detect the foot pressure on the temples 40. The electrostrictive element 42 extends and retracts along a second direction B based on the foot pressure to adjust the tightness of the smart glasses. By providing an adjustment assembly within the temples 40, the accuracy and efficiency of adjusting the tightness of the smart glasses can be further enhanced in conjunction with the extension and retraction of the temples 20.

[0045] Specifically, the electrostrictive element 42 also exhibits an electrostrictive effect. Spontaneously formed molecular clusters, or electric domains, exist within the electrostrictive element 42. These electric domains are capable of polarization, causing changes in the length of the electrostrictive element 42 along the polarization direction to achieve expansion and contraction. Under the influence of an applied electric field, the polarization direction of the electric domains is the same as the direction of the external electric field. Therefore, by controlling the direction of the applied electric field along the second direction B, the electrostrictive element 42 can be controlled to lengthen or shorten along the second direction B.

[0046] In this embodiment, specifically, both the pressure detector 41 and the electrostrictive element 42 are electrically connected to the voltage controller 13. The voltage controller 13 outputs voltage to the electrostrictive element 42 based on the foot pressure, thereby controlling the electrostrictive element 12 to extend and retract along the second direction B. Precise control of the extension and retraction amplitude of the electrostrictive element 42 is achieved through the pressure controller.

[0047] In practical applications, a preset foot pressure can be set. When the pressure detector 41 detects that the foot pressure of the temple 40 is less than the preset foot pressure, the voltage controller 13 increases the voltage output to make the electrostrictive component 42 produce. When the pressure detector 41 detects that the foot pressure of the temple 40 is greater than the preset foot pressure, the voltage controller 13 decreases the voltage output to make the electrostrictive component 42 shorten until the foot pressure of the pressure detector 41 is the preset foot pressure, so as to adjust the tightness of the smart glasses to a suitable degree.

[0048] In some optional embodiments of this application, the smart glasses are equipped with a button electrically connected to a pressure sensor 11. In response to a press operation on the button, the electro-deformable element 12 starts or stops extending or retracting based on the pressure value of the pressure sensor 11. Thus, the massage function of the smart glasses can be activated with a single button press, which is convenient and quick.

[0049] Optionally, in this embodiment, an energy-reducing crystal may be disposed within the electrodeformable element 12. The energy-reducing crystal is embedded in the electrodeformable element 12 to reduce the energy consumption of the smart glasses. Typically, the electrodeformable element 12 consumes a significant amount of electrical energy. By embedding the energy-reducing crystal in the electrodeformable element 12, the conductivity of the electrodeformable element 12 can be enhanced, thereby reducing energy consumption and saving energy.

[0050] For example, the material of the energy-reducing crystal may include graphene, carbon nanotubes, etc., but the specific material of the energy-reducing crystal is not limited in the embodiments of this application.

[0051] In summary, the smart glasses described in this application embodiment may include at least the following advantages:

[0052] In this embodiment, the smart glasses include a frame, temples, and nose pads. Both the temples and nose pads are connected to the frame. At least one of the temples and nose pads is equipped with a massage component. The massage component includes a pressure sensor and an electro-deformable element. The pressure sensor is connected to at least one of the temples and nose pads and detects the pressure value of at least one of the temples and nose pads. The electro-deformable element expands and contracts at a preset frequency based on the pressure value. When the nose pads are equipped with a massage component, the pressure sensor detects the pressure value of the nose pads, which also represents the pressure on the bridge of the nose. The electro-deformable element can expand and contract based on the pressure value of the nose pads, causing the nose pads to massage the bridge of the nose at a preset frequency, thereby relieving discomfort and fatigue caused by pressure from the nose pads. When the temples are equipped with massage components, pressure sensors detect the pressure value of the temples, which also represents the pressure on the auricle. Electro-deformable components can then expand and contract based on this pressure value, causing the temples to massage the auricle, such as the temples, at a preset frequency. This relieves discomfort and fatigue caused by pressure from the temples. When both the nose pads and temples are equipped with massage components, pressure sensors can simultaneously detect the pressure on both. This allows the nose pads to massage the bridge of the nose while the temples massage the auricle, further alleviating soreness and discomfort caused by prolonged wear of smart glasses and improving user comfort.
