Description

Technical Field

[0001] This invention relates to the field of smart glasses technology, and in particular to a smart pair of glasses and its charging method. Background Technology

[0002] With the development and popularization of smart glasses, more and more people are starting to use them. Users' requirements for the battery life of smart glasses are also gradually increasing. Because the basic shape of the glasses must be maintained, the battery capacity cannot be increased at will. Therefore, the battery capacity is limited, which makes it difficult to improve the battery life of existing smart glasses. Summary of the Invention

[0003] The main objective of this invention is to propose a smart glasses and its charging method, aiming to solve the technical problem of how to improve the battery life of smart glasses.

[0004] To achieve the above objectives, the present invention proposes smart glasses, which include a frame and temples connected to the frame, wherein the temples have an interior cavity and an opening communicating with the cavity.

[0005] The smart glasses also include a photosensitive element, a driving module, a control module, and a power module. The driving module includes a first driving component, a blocking component, and a photovoltaic component. The photovoltaic component is connected to the blocking component. Both the blocking component and the photovoltaic component are located within the mounting cavity. The blocking component has a blocking position and an exposed position. The first driving component is drively connected to the blocking component and / or the photovoltaic component.

[0006] The power supply module is electrically connected to the photovoltaic module. The first driving component and the photosensitive element are both communicatively connected to the control module. The photosensitive element can output light intensity information to the control module according to the intensity of the light source. The control module can control the first driving component to drive the blocking component to reciprocate between the blocking position and the exposed position according to the light intensity information. When the blocking component is in the blocking position, the blocking component covers the opening. When the blocking component is in the exposed position, the light emitted by the light source can pass through the opening and be emitted to the photovoltaic module.

[0007] In one embodiment, the smart glasses further include a positioning module disposed on the temple, the blocking component being located at the exposed position, the positioning module being detachably connected to the blocking component, and the positioning module being able to restrict the blocking component from leaving the exposed position.

[0008] In one embodiment, the positioning module includes a second driving component and a locking block. The second driving component is tractively connected to the locking block and is disposed within the mounting cavity. The shielding component includes a shielding plate having a shielding position and an exposed position. The shielding plate is connected to the photovoltaic module and has a locking hole located at the exposed position. The locking hole faces the locking block. The second driving component can drive the locking block to extend into or disengage from the locking hole.

[0009] In one embodiment, the second driving component includes an electromagnet and a reset elastic element. The locking block is made of a magnetic material. When the electromagnet is energized, it can drive the locking block to disengage from the locking hole. When the electromagnet is de-energized, the reset elastic element can drive the locking block to extend into the locking hole.

[0010] In one embodiment, the end of the locking block facing away from the reset elastic member has a top surface, and the side wall of the locking block has a side surface facing the photovoltaic module. The locking block has a guide slope connecting the top surface and the side surface. The guide slope is inclined in a first direction away from the photovoltaic module. The first driving component drives the blocking component, which moves towards the exposure position, to abut against the guide slope and move relative to the guide slope, so that the locking block moves towards the electromagnet until the top surface of the locking block abuts against the bottom surface of the blocking component.

[0011] In one embodiment, the smart glasses further include a position sensor. The card block has a latching position and a disengaging position. The second driving component can drive the card block to reciprocate between the latching position and the disengaging position. The card block is located in the latching position and inside the card hole. The card block is located in the disengaging position and outside the card hole. The position sensor is used to detect whether the card block is located in the disengaging position. The position sensor is communicatively connected to the control module. When the position sensor detects that the card block has left the disengaging position, the control module controls the first driving component to stop driving the blocking component to move away from the blocking position.

[0012] In one embodiment, the first driving component includes a shape memory alloy spring. When the shape memory alloy spring is energized, it can drive the blocking component to move from the blocking position to the exposed position. When the shape memory alloy spring is de-energized, it can drive the blocking component to move from the exposed position to the blocking position.

[0013] And / or, the blocking component slides against the inner wall of the temple;

[0014] And / or, the photovoltaic module slides into contact with the inner wall of the temple.

[0017] And / or, the temple is further provided with a mounting groove for accommodating the photosensitive element, the photosensitive element is located in the mounting groove, and the photosensitive side of the photosensitive element is exposed through the groove opening of the mounting groove.

[0018] In one embodiment, the number of temples includes two, and each temple is hinged to the frame.

[0020] In one embodiment, the smart glasses further include lenses disposed on the frame;

[0021] And / or, the smart glasses further include a sound module located within the mounting cavity, and the temples are provided with sound holes communicating with the mounting cavity.

[0022] This invention also proposes a charging method for smart glasses, which is applied to the aforementioned smart glasses and includes the following steps:

[0023] Real-time control of the photosensitive element to acquire light intensity information of the light source;

[0024] The control module determines whether the intensity of the light source meets the preset light intensity requirements based on the light intensity information.

[0025] If the intensity of the light source meets the preset light intensity requirement, the first driving component is controlled to move the blocking component to the exposure position, so that the photovoltaic module is exposed through the opening.

[0026] If the intensity of the light source does not meet the preset light intensity requirement, the first driving component is controlled to move the blocking component to the blocking position so that the blocking component closes the mounting cavity.

[0027] In one embodiment, the smart glasses further include a positioning module, the positioning module including a second driving component and a locking block, the second driving component being tractively connected to the locking block, the blocking component including a blocking plate having a blocking position and an exposure position, the blocking plate being connected to the photovoltaic module, the blocking plate having a locking hole, the blocking plate being located at the exposure position, and the locking hole being oriented towards the locking block; the step of controlling the first driving component to move the blocking component to the exposure position includes:

[0028] The first driving component is controlled to move the cover plate to the exposed position, and the second driving component is controlled to move the card block into the card hole;

[0029] The step of controlling the first driving component to move the blocking component to the blocking position includes:

[0030] The second driving component is controlled to disengage the card block from the card hole, and the first driving component is controlled to move the shielding plate to the shielding position.

[0031] The smart glasses also include a position sensor. The shield also has a middle position between the shielding position and the exposed position. The second driving component includes an electromagnet and a reset elastic element. The locking block is made of magnetic material. When the electromagnet is energized, it can drive the locking block to disengage from the locking hole. When the electromagnet is de-energized, the reset elastic element can drive the locking block to extend into the locking hole. The locking block has a locking position and a disengaging position. The locking block is located in the locking position, inside the locking hole, in the disengaging position, or outside the locking hole. The shielding component is in the middle position, the locking block is in the disengaging position, and the top surface of the locking block abuts against the bottom surface of the shielding component. The position sensor is used to detect whether the locking block is in the disengaging position.

[0032] The steps of controlling the first driving component to move the cover plate to the exposed position and controlling the second driving component to move the card block into the card hole include:

[0033] Control the first driving component to move the baffle to the middle position;

[0034] The position sensor is controlled in real time to detect whether the card block is in the disengaged position, and the first drive component is controlled to move the cover plate to the exposed position.

[0035] If the reset elastic element causes the card block to leave the disengagement position and extend into the card hole, then the first drive component is powered off.

[0036] And / or,

[0037] The steps of controlling the second driving component to disengage the card block from the card hole and controlling the first driving component to move the baffle to the baffle position include:

[0038] The electromagnet is energized to attract the card block and detach it from the card slot;

[0039] The first driving component is controlled to move the baffle to the baffle position, and the position sensor is controlled to detect whether the card block is in the disengagement position;

[0040] If the locking block is in the disengaged position, the electromagnet is de-energized.

[0041] The technical solution of this invention detects the intensity of a light source by setting a photosensitive element. When the intensity of the light source meets the preset light intensity requirement, the first driving component drives the blocking component located in the blocking position to move relative to the temple towards the exposed position. Since the blocking component is connected to the photovoltaic component, the photovoltaic component will also move with the blocking component. When the blocking component is in the exposed position, the photovoltaic component moves just below the opening. The light emitted from the light source can pass through the opening and be emitted onto the photovoltaic component. The photovoltaic component can convert light energy into electrical energy and send the electrical energy to the power module for storage, thereby improving the battery life of the smart glasses.

[0060] With the development and popularization of smart glasses, more and more people are starting to use them. Users' requirements for the battery life of smart glasses are also gradually increasing. Because the basic shape of the glasses must be maintained, the battery capacity cannot be increased at will. Therefore, the battery capacity is limited, which makes it difficult to improve the battery life of existing smart glasses.

[0061] The inventors discovered that since there are light sources in some scenarios where users wear glasses, if these light sources are utilized to generate electricity, the battery life of smart glasses can be improved without changing the battery capacity.

[0062] This invention proposes a smart glasses solution aimed at solving the technical problem of improving the battery life of smart glasses.

[0063] Please see Figures 1 to 4 In one embodiment of the present invention, the smart glasses 100 includes a frame 1 and temples 2 connected to the frame 1. The temples 2 have an internal mounting cavity 21 and an opening 22 communicating with the mounting cavity 21.

[0064] The smart glasses 100 also includes a photosensitive element 3, a driving module 4, a control module 5, and a power module 6. The driving module 4 includes a first driving component 41, a blocking component 42, and a photovoltaic component 43. The photovoltaic component 43 is connected to the blocking component 42. Both the blocking component 42 and the photovoltaic component 43 are located within the mounting cavity 21. The blocking component 42 has a blocking position and an exposed position. The first driving component 41 is drively connected to the blocking component 42 and / or the photovoltaic component 43. The power module 6 is electrically connected to the photovoltaic component 43. Both the first driving component 41 and the photosensitive element 3 are communicatively connected to the control module 5. The photosensitive element 3 can output light intensity information to the control module 5 according to the intensity of the light source. The control module 5 can control the first driving component 41 to drive the blocking component 42 to reciprocate between the blocking position and the exposed position according to the light intensity information. When the blocking component 42 is in the blocking position, the blocking component 42 covers the opening 22. When the blocking component 42 is in the exposed position, the light emitted from the light source can pass through the opening 22 and be emitted to the photovoltaic component 43.

[0065] The technical solution of this invention uses a photosensitive element 3 to detect the intensity of the light source and outputs light intensity information to a control module 5. The control module 5 determines whether the current light source intensity meets the preset light intensity requirement based on the light intensity information. If the current light source intensity meets the preset light intensity requirement, it controls the first driving component 41 to move the blocking component 42 away from the blocking position and towards the exposure position. Since the blocking component 42 is connected to the photovoltaic component 43, the photovoltaic component 43 will also move along with the blocking component 42. When the blocking component 42 is in the exposure position, the photovoltaic component 43 has just moved below the opening 22, and the light emitted from the light source can pass through the opening 22 and be emitted onto the photovoltaic component 43. The photovoltaic module 43 can convert light energy into electrical energy and transmit the electrical energy to the power module 6 for storage or directly to power electronic components, thereby improving the battery life of the smart glasses 100. For smart glasses 100 that are frequently used outdoors, the smart glasses 100 of this embodiment not only meets the application scenario, but also uses solar energy, which is a clean energy source and is therefore more environmentally friendly. When the light source intensity does not meet the preset light intensity requirement, the first driving component 41 drives the blocking component to move from the exposed position to the blocking position. The blocking component 42 located at the blocking position will cover the opening 22, thereby closing the mounting cavity 21. The photovoltaic module 43 connected to the blocking component 42 will move with the opening 22. As the shading component 42 moves away from the opening 22, and both the shading component 42 and the photovoltaic module 43 are located in the mounting cavity 21, the photovoltaic module 43 is now within the closed mounting cavity 21 after the shading component 42 covers the opening 22. Since the photovoltaic module 43 is made of fragile material (generally glass), the inventors considered that if the photovoltaic module 43 were constantly exposed, it would be easily damaged by external impacts, posing a safety risk. Therefore, in this embodiment, when the light source intensity is insufficient, the shading component 42 encloses the photovoltaic module 43 within the mounting cavity 21, reducing the risk of breakage. Simultaneously, even if the photovoltaic module 43... The broken photovoltaic module 43, located within the enclosed mounting cavity 21, does not pose a corresponding safety risk, effectively improving the safety performance of the smart glasses 100. Simultaneously, the inventors considered that if the photovoltaic module 43 were constantly exposed, external dust or other foreign objects could easily adhere to its surface, affecting its light absorption efficiency. In this embodiment, when the light source intensity is insufficient, a shielding component encloses the photovoltaic module 43 within the mounting cavity 21, effectively preventing foreign objects from adhering to it. This ensures that when the light source intensity meets the preset light intensity requirement, the photovoltaic module 43 can fully receive light energy. The opening 22 is located above the temple 2, facilitating the light emitted from the light source to illuminate the photovoltaic module 43 through the opening 22.

[0066] It should be noted that in this embodiment, the shielding component 42 and the photovoltaic component 43 are arranged sequentially along the length of the temple 2, thereby making full use of the space within the mounting cavity 21. Compared to a stacked arrangement of the photovoltaic component 43 and the shielding component 42, this saves space in the thickness direction, allowing for the accommodation of a larger power module 6, thus improving the battery life of the smart glasses 100. The length of the temple 2 is... Figure 4 The front and back directions are shown.

[0067] It should also be noted that the first drive component 41 and the power module 6 can be located inside the mounting cavity 21 or outside the mounting cavity 21, without any restriction; the control module 5 can be located on the temple 2 or not, for example, a mobile phone, tablet or other terminal can be used as the control module 5, without any restriction. It should also be noted that the photosensitive element 3 can be a photoresistor, photodiode, digital light intensity sensor, etc.; the shading component 42 can be a shading plate 42A or a shading block; the power module 6 includes at least one battery, and the number of batteries can be selected according to needs and is not limited here; in addition, the photovoltaic module 43 can be a monocrystalline silicon photovoltaic panel 43A, a polycrystalline silicon photovoltaic panel 43A, or a thin-film photovoltaic panel 43A, and there are no specific restrictions here. The shading component 42 and the photovoltaic module 43 can be bonded or snap-fitted together. For example, the shading component 42 is provided with a connecting post, and the photovoltaic module 43 is provided with a connecting hole for the connecting post to pass through. There are no specific restrictions on the connection form between the shading component 42 and the photovoltaic module 43.

[0068] Please see Figures 2 to 5 In one embodiment, the smart glasses 100 further includes a positioning module 7, which is disposed on the temple 2. The blocking component 42 is located in the exposed position. The positioning module 7 and the blocking component 42 are detachably connected. The positioning module 7 can restrict the blocking component 42 from leaving the exposed position. By setting the positioning module 7, when the blocking component 42 is in the exposed position, the positioning module 7 is connected to the blocking component 42, thereby restricting the blocking component 42 from leaving the exposed position. This ensures that the photovoltaic module 43 can stably stay at the opening 22 when the light source intensity meets the preset light intensity requirement, thereby improving the stability and reliability of the light energy conversion of the photovoltaic module 43. When the light source intensity does not meet the preset light intensity requirement, the positioning module 7 is disconnected from the blocking component 42, so that the first driving component 41 can drive the blocking component 42 to move from the exposed position to the blocked position.

[0069] According to an embodiment of the present invention, the positioning module 7 includes a positioning pin, and the blocking component 42 includes a blocking plate 42A. The blocking plate 42A has a positioning hole. When the blocking plate 42A is in the exposed position, the positioning pin passes through the positioning hole, thereby restricting the blocking plate 42A from leaving the exposed position. When the positioning pin leaves the positioning hole, the first driving component 41 can drive the blocking plate 42A to leave the exposed position.

[0070] Please see Figures 3 to 5 In one embodiment, the positioning module 7 includes a second driving component 71 and a locking block 72. The second driving component 71 is connected to the locking block 72 in a transmission manner. The second driving component 71 is disposed in the mounting cavity 21. The shielding component 42 includes a shielding plate 42A. The shielding plate 42A has a shielding position and an exposed position. The shielding plate 42A is connected to the photovoltaic module 43. The shielding plate 42A has a locking hole 421. The shielding plate 42A is located in the exposed position. The locking hole 421 is set facing the locking block 72. The second driving component 71 can drive the locking block 72 to extend into or disengage from the locking hole 421. When the shield 42A is in the exposed position, the locking hole 421 is located above the locking block 72. The second drive assembly 71 drives the locking block 72 to rise, so that the locking block 72 extends into the locking hole 421. The cooperation between the locking block 72 and the locking hole 421 restricts the shield 42A from leaving the exposed position. When the second drive assembly 71 drives the locking block 72 to fall away from the locking hole 421, the shield 42A can leave the exposed position under the drive of the first drive assembly 41 because it is no longer limited by the locking block 72.

[0071] It should be noted that the first drive assembly 41 and the second drive assembly 71 can be either a motor or an electric actuator, without specific limitations. The second drive assembly 71 can be directly connected to the locking block 72, or it can be connected to the locking block 72 via a gear and rack transmission, again without specific limitations. For example, the output shaft of the electric actuator can be directly connected to the locking block 72, and the electric actuator can directly drive the locking block 72 to move up and down; or the output shaft of the motor can be connected to a gear, the gear can mesh with a rack, and the rack can be connected to the locking block 72. In this case, the motor drives the gear to rotate, and the rotating gear drives the rack to rise and fall, thereby driving the locking block 72 connected to the rack to move up and down.

[0072] Please see Figure 3 and Figure 5In one embodiment, the second driving component 71 includes an electromagnet 711 and a reset elastic member 712. The locking block 72 is made of magnetic material. When the electromagnet 711 is energized, it can drive the locking block 72 to disengage from the locking hole 421. When the electromagnet 711 is de-energized, the reset elastic member 712 can drive the locking block 72 to extend into the locking hole 421. When the electromagnet 711 is energized, it attracts the locking block 72 and moves it downward. At this time, the reset elastic member 712 is compressed. Therefore, when the electromagnet 711 is energized, it can drive the locking block 72 to move downward and disengage from the locking hole 421. When the electromagnet 711 is de-energized and the reset elastic member 712 is compressed, the reset elastic member 712 can drive the locking block 72 to move upward. Therefore, the reset elastic member 712 can drive the locking block 72 to move upward and extend into the locking hole 421. By setting up an electromagnet 711 and a reset elastic element 712, the automatic engagement or disengagement of the locking block 72 and the locking hole 421 is achieved.

[0073] Please see Figures 3 to 5 In one embodiment, the end of the locking block 72 away from the reset elastic member 712 is provided with a top surface 721, and the side wall of the locking block 72 facing the photovoltaic module 43 is provided with a side surface 722. The locking block 72 is provided with a guide slope 723 connecting the top surface 721 and the side surface 722. The guide slope 723 is inclined in a first direction away from the photovoltaic module 43. The first driving component 41 drives the shading component 42, which moves towards the exposure position, to abut against the guide slope 723 and move relative to the guide slope 723, so that the locking block 72 moves towards the electromagnet 711 until the top surface 721 of the locking block 72 abuts against the bottom surface of the shading component 42. By setting the guide ramp 723, when the first driving assembly 41 drives the baffle 42A to move to the left, the baffle 42A will first contact the guide ramp. As the baffle 42A continues to move to the left, the guide ramp 723 will guide the locking block 72 to move downward, avoiding interference between the locking block 72 and the baffle 42A. The downward-moving locking block 72 will compress the reset elastic member 712 until the top surface 721 of the locking block 72 abuts against the bottom surface of the baffle 42A. The locking block 72 stops moving downward and is pressed against the bottom surface of the baffle 42A by the reset elastic member 712. The baffle 42A continues to move to the left until the baffle 42A moves to the exposed position. At this time, the locking hole 421 is located above the locking block 72. The reset elastic member 712 then drives the locking block 72 to move upward so that the locking block 72 extends into the locking hole 421. The reset elastic element 712 can be a spring or a rubber pad; it should be noted that the number of reset elastic elements 712 can be two or more. The first direction is... Figure 4 The direction shown is from bottom to top.

[0074] Please see Figure 5In one embodiment, the smart glasses 100 further includes a position sensor 8. The locking block 72 has a locking position and a disengaging position. The second driving component 71 can drive the locking block 72 to reciprocate between the locking position and the disengaging position. When the locking block 72 is in the locking position, the locking block 72 is located inside the card hole 421. When the locking block 72 is in the disengaging position, the locking block 72 is located outside the card hole 421. The position sensor 8 is used to detect whether the locking block 72 is in the disengaging position. The position sensor 8 is communicatively connected to the control module 5. When the position sensor 8 detects that the locking block 72 has left the disengaging position, the control module 5 controls the first driving component 41 to stop driving the blocking component 42 to move away from the blocking position. The position sensor 8 is used to acquire the position information of the locking block 72, thereby determining whether the locking block 72 is in the disengaged position. When the first drive assembly 41 drives the baffle plate 42A to move to the left, before the baffle plate 42A contacts the locking block 72, the locking block 72 is at the height of the engagement position. The baffle plate 42A, moving to the left, will first contact the guide ramp. As the baffle plate 42A continues to move to the left, the guide ramp 723 will guide the locking block 72 to move downwards until the top surface 721 of the locking block 72 abuts against the bottom surface of the baffle plate 42A. At this time, the locking block 72 moves to the disengaged position. The position sensor 8 detects that the locking block 72 has moved from the height of the engagement position to the disengaged position, and then the mechanism is activated. The system continuously monitors whether the locking block 72 is in the disengaged position. When the shielding plate 42A moves to the exposed position, the locking hole 421 is located above the locking block 72. The reset elastic element 712 then drives the locking block 72 to move upward from the disengaged position to the engaged position. After the position sensor 8 detects that the locking block 72 has left the disengaged position, it sends the information to the control module 5. The control module 5 then cuts off the power to the first drive component 41 based on this information, thereby stopping the action of the first drive component 41. That is, it stops the first drive component 41 from continuing to drive the shielding plate 42A and the photovoltaic module 43 to move to the left, thus avoiding the squeezing damage between the shielding plate 42A and the locking block 72, and also saving the energy consumption of the first drive component 41.

[0075] Please see Figures 2 to 4In one embodiment, the first driving component 41 includes a shape memory alloy spring 41A. When the shape memory alloy spring 41A is energized, it can drive the blocking component 42 to move from the blocking position to the exposed position. When the shape memory alloy spring 41A is de-energized, it can drive the blocking component 42 to move from the exposed position to the blocking position. The shape memory alloy spring 41A is a spring made of shape memory alloy wire, which has the characteristic of increasing length when energized and decreasing in temperature when de-energized to restore its original length. Therefore, in this embodiment, when the blocking plate 42 is needed... When A and photovoltaic module 43 move to the left, the memory alloy spring 41A is energized, causing the temperature of the memory alloy spring 41A to rise and its length to extend, thereby driving the shielding plate 42A and photovoltaic module 43 to move to the left to the exposed position. When the memory alloy spring 41A is de-energized, due to its characteristics, the memory alloy spring 41A will return to its original length, so the memory alloy spring 41A can then drive the shielding plate 42A and photovoltaic module 43 to move to the right together from the exposed position to the shielded position. The use of memory alloy spring 41A results in a simple structure and low weight, which facilitates the assembly and lightweight design of smart glasses 100.

[0076] In one embodiment, the shielding component 42 slides against the inner wall of the temple 2; the shielding plate 42A slides against the inner wall of the temple 2, thereby enabling the shielding plate 42A and the photovoltaic module 43 connected to the shielding plate 42A to reciprocate in a defined direction, improving the stability of the shielding plate 42A's movement. Specifically, the shielding plate 42A may be provided with a slide rail, and the inner wall of the mounting cavity 21 may be provided with a groove that slides against the slide rail; or the shielding plate 42A may be provided with a groove, and the inner wall of the mounting cavity 21 may protrude inward to form a slide rail that slides against the groove.

[0077] In one embodiment, the photovoltaic module 43 is slidably engaged with the inner wall of the temple 2. This slidable engagement allows the shielding plate 42A and the photovoltaic module 43 connected to it to reciprocate in a defined direction, improving the stability of the photovoltaic module 43's movement. Alternatively, a slide rail may be provided on the photovoltaic module 43, and a groove may be provided on the inner wall of the mounting cavity 21 to slidably engage with the slide rail; or the photovoltaic module 43 may have a groove, and the inner wall of the mounting cavity 21 may protrude inward to form a slide rail that slidably engages with the groove.

[0078] In one embodiment, the photovoltaic module 43 includes at least one photovoltaic panel 43A; each photovoltaic panel 43A is disposed facing the opening 22; by disposing of multiple photovoltaic panels 43A, the light energy conversion efficiency is effectively improved, thereby further increasing the battery life of the smart glasses 100.

[0079] Please see Figure 2 and Figure 3In one embodiment, the control module 5 includes a circuit board 5A. Both the circuit board 5A and the power module 6 are disposed within the mounting cavity 21. The first driving component 41 and the photosensitive element 3 are electrically connected to the circuit board 5A. Both the circuit board 5A and the power module 6 are disposed on the side of the photovoltaic module 43 facing away from the opening 22. The power module 6 is located on the side of the circuit board 5A facing away from the photovoltaic module 43. By placing the power module 6 and the circuit board 5A on the side of the photovoltaic module 43 facing away from the opening 22, the phenomenon of the circuit board 5A or the power module 6 blocking the light emitted from the light source is avoided. The circuit board 5A is located below the photovoltaic module 43, and the power module 6 is located below the circuit board 5A.

[0080] Please see Figure 1 and Figure 2 In one embodiment, the temple 2 is further provided with a mounting groove 23 for accommodating the photosensitive element 3. The photosensitive element 3 is located within the mounting groove 23, and the photosensitive side of the photosensitive element 3 is exposed through the opening of the mounting groove 23. By providing the mounting groove 23 to accommodate the photosensitive element 3, the overall aesthetics of the smart glasses 100 are improved, and the phenomenon that the photosensitive element 3, which is located on the outside of the temple 2, is easily damaged by collisions with external objects is also avoided.

[0081] Please see Figure 1 In one embodiment, the number of temples 2 includes two, and each temple 2 is hinged to the frame 1. The fact that there can be two temples 2 improves the stability of wearing the smart glasses 100.

[0082] In one embodiment, the number of photosensitive elements 3 and temples 2 are the same and correspond one-to-one, the number of driving modules 4 and temples 2 are the same and correspond one-to-one, the number of control modules 5 and temples 2 are the same and correspond one-to-one, and the number of power modules 6 and temples 2 are the same and correspond one-to-one. The fact that the number of photosensitive elements 3, driving modules 4, control modules 5, and power modules 6 are all the same and correspond one-to-one with the number of temples 2 ensures that when the light source intensity meets the preset light intensity requirement, the photovoltaic modules 43 located on both temples 2 can absorb light energy, thereby effectively improving the battery life of the smart glasses 100.

[0083] Please see Figure 1 In one embodiment, the smart glasses 100 also includes a lens 9 disposed on the frame 1; the lens 9 is disposed on the frame 1 so as to meet the needs of different users for the lens 9.

[0084] Please see Figures 2 to 4In one embodiment, the smart glasses 100 further includes a sound module 10, which is located within the mounting cavity 21. The temple 2 also has a sound hole 24 communicating with the mounting cavity 21. By adding the sound module 10, the functionality of the smart glasses 100 is enriched, and by placing the sound module 10 within the mounting cavity 21, the space utilization of the mounting cavity 21 is effectively improved.

[0085] The charging method for the smart glasses 100 can be as follows: the photosensitive element 3 detects the intensity of the light source and outputs light intensity information to the control module 5. The control module 5 determines whether the current light source intensity meets the preset light intensity requirement based on the light intensity information. If the current light source intensity meets the preset light intensity requirement, the memory alloy spring 41A is energized and drives the shield 42A to move away from the shielding position and towards the exposure position. Before reaching the exposure position, the shield 42A will first contact the guide slope 723. As the shield 42A continues to move to the left, the guide slope 723... The inclined plane 723 guides the locking block 72 to move downwards, preventing interference between the locking block 72 and the baffle plate 42A. The downward-moving locking block 72 compresses the reset elastic element 712 until its top surface 721 abuts against the bottom surface of the baffle plate 42A. The locking block 72 stops moving downwards and is held against the bottom surface of the baffle plate 42A by the reset elastic element 712. At this point, the locking block 72 is in the disengaged position. The position sensor 8 continuously monitors whether the locking block 72 has left the disengaged position. The baffle plate 42A continues to move to the left until it reaches the exposed position, at which point the locking hole... Position 421 is located above the locking block 72. The reset elastic element 712 drives the locking block 72 to move upward, causing the locking block 72 to extend into the locking hole 421. The position sensor 8 detects that the locking block 72 has left the disengaged position, so the control module 5 controls the memory alloy spring 41A to be de-energized. Since the locking block 72 is located inside the locking hole 421, the memory alloy spring 41A cannot drive the shield 42A away from the exposed position after the power is de-energized. When the light source intensity does not meet the preset light intensity requirement, the electromagnet 711 is energized, thereby generating a downward attraction force on the locking block 72 and driving the locking block 72. As the module moves downward away from the locking hole 421, the lack of locking block 72 causes the shape memory alloy spring 41A to move the shielding plate 42A to the right, moving away from the exposed position and towards the shielding position. At the same time, the position sensor 8 detects that the locking block 72 has disengaged from the locking hole 421. For example, if the locking block 72 moves to the disengaged position or continues to move downward after passing the disengaged position, the electromagnet 711 is de-energized, thereby saving energy. When the shielding plate 42A is in the shielding position, the shielding plate 42A covers the opening 22, and the photovoltaic module 43 is enclosed in the mounting cavity 21 and hidden.

[0086] Please see Figure 6 , Figure 6 This is a flowchart illustrating the first embodiment of the charging method for smart glasses provided by the present invention; please refer to [link / reference]. Figure 7 , Figure 7This is a flowchart illustrating a second embodiment of the charging method for smart glasses provided by the present invention. The present invention also proposes a charging method for smart glasses, which is applied to the aforementioned smart glasses. The charging method for smart glasses includes the following steps:

[0087] S100, real-time control of the photosensitive element to acquire light intensity information of the light source;

[0088] By using photosensitive elements to detect the light intensity of light sources in real time, it is possible to understand the changes in the light intensity of the current environment.

[0089] S200, the control module determines whether the intensity of the light source meets the preset light intensity requirement based on the light intensity information;

[0090] The control module determines whether the intensity of the current light source meets the preset light intensity requirement based on the light intensity information obtained by the photosensitive element. The preset light intensity requirement can be a preset light intensity value or a preset light intensity range. Taking a preset light intensity value as an example, the light intensity information obtained by the photosensitive element includes the light intensity value of the current light source. The control module determines whether the intensity of the current light source meets the preset light intensity requirement by comparing the current light intensity value with the preset light intensity value.

[0091] S210, if the intensity of the light source meets the preset light intensity requirement, control the first driving component to move the blocking component to the exposure position; so that the photovoltaic module is exposed through the opening;

[0092] If the light intensity of the current light source is greater than or equal to the preset light intensity value, it means that the intensity of the current light source meets the preset light intensity requirement. Therefore, by controlling the first driving component, the blocking component is moved away from the blocking position and towards the exposure position. Since the blocking component is connected to the photovoltaic component, the photovoltaic component will also move with the blocking component. When the blocking component is in the exposure position, the photovoltaic component moves just below the opening. The light emitted from the light source can pass through the opening and be emitted onto the photovoltaic component. The photovoltaic component can convert light energy into electrical energy and deliver the electrical energy to the power module for storage or directly supply the electronic components, thereby improving the battery life of the smart glasses.

[0093] S220, if the intensity of the light source does not meet the preset light intensity requirement, the first driving component is controlled to move the blocking component to the blocking position so that the blocking component closes the mounting cavity.

[0094] When the light source intensity does not meet the preset light intensity requirement, the first driving component drives the shielding component to move from the exposed position to the shielding position. The shielding component located in the shielding position will cover the opening, thereby closing the mounting cavity. The photovoltaic module connected to the shielding component will leave the opening as the shielding component moves. Since both the shielding component and the photovoltaic module are located in the mounting cavity, the photovoltaic module is in the closed mounting cavity after the shielding component covers the opening.

[0095] The technical solution of this invention uses a photosensitive element to detect the intensity of a light source and outputs light intensity information to a control module. The control module determines whether the current light source intensity meets a preset light intensity requirement based on this information. If the current light source intensity meets the preset light intensity requirement, the first driving component moves the blocking component away from the blocking position and towards the exposure position. Since the blocking component is connected to the photovoltaic module, the photovoltaic module also moves with the blocking component. When the blocking component is in the exposure position, the photovoltaic module moves just below the opening, allowing light emitted from the light source to pass through the opening and reach the photovoltaic module. The photovoltaic module converts light energy into electrical energy and transmits the electrical energy to the power module for storage or directly supplies it to electronic components, thereby improving the battery life of the smart glasses. For smart glasses frequently used outdoors, the smart glasses of this embodiment not only meet this application scenario but also use solar energy, a clean energy source, making them more environmentally friendly. When the light source intensity does not meet the preset light intensity requirement, the first driving component moves the blocking component from the exposure position to the blocking position. The blocking component in the blocking position covers the opening, thereby sealing the mounting cavity and connecting with the blocking component. The connected photovoltaic (PV) module moves away from the opening as the shading component moves. Since both the shading component and the PV module are located in the mounting cavity, the PV module is inside the closed mounting cavity after the shading component covers the opening. Because the PV module material is fragile, the inventors considered that if the PV module is constantly exposed, it is easily damaged by external impacts, posing a safety risk. Therefore, in this embodiment, when the light source intensity is insufficient, the shading component encloses the PV module within the mounting cavity, reducing the risk of breakage. Even if the PV module breaks, the broken pieces are within the closed mounting cavity and do not pose a corresponding safety risk, effectively improving the safety performance of the smart glasses. Furthermore, the inventors also considered that if the PV module is constantly exposed, dust or other foreign objects can easily adhere to its surface, affecting its light absorption efficiency. In this embodiment, when the light source intensity is insufficient, the shading component encloses the PV module within the mounting cavity, effectively preventing foreign objects from adhering to the PV module. This ensures that when the light source intensity meets the preset light intensity requirements, the PV module can fully receive light energy.

[0096] Please see Figure 8 , Figure 8 This is a flowchart illustrating a third embodiment of the charging method for smart glasses provided by the present invention; please refer to [link / reference]. Figure 9 , Figure 9 This is a flowchart illustrating a fourth embodiment of the charging method for smart glasses provided by the present invention. In one embodiment, the smart glasses further include a positioning module, which includes a second driving component and a locking block. The second driving component is convexly connected to the locking block. The blocking component includes a blocking plate having a blocking position and an exposed position. The blocking plate is connected to the photovoltaic module. The blocking plate has a locking hole located at the exposed position, and the locking hole faces the locking block. The step of controlling the first driving component to move the blocking component to the exposed position includes:

[0097] S211, control the first driving component to move the cover plate to the exposed position, and control the second driving component to move the card block into the card hole;

[0098] The step of controlling the first driving component to move the blocking component to the blocking position includes:

[0099] S221, control the second driving component to drive the card block to disengage from the card hole, and control the first driving component to drive the shield to move to the shielding position.

[0100] By setting up a positioning module, when the shading component is in the exposed position, the positioning module is connected to the shading component, thereby restricting the shading component from leaving the exposed position. This ensures that the photovoltaic module can stably stay at the opening when the light source intensity meets the preset light intensity requirement, improving the stability and reliability of the photovoltaic module's light energy conversion. When the light source intensity does not meet the preset light intensity requirement, the positioning module is disconnected from the shading component, so that the first driving component can drive the shading component to move from the exposed position to the shading position.

[0101] Please see Figure 10 , Figure 10 This is a flowchart illustrating the fifth embodiment of the charging method for smart glasses provided by the present invention; please refer to [link / reference]. Figure 11 , Figure 11This is a flowchart illustrating a sixth embodiment of the charging method for smart glasses provided by the present invention. The smart glasses further include a position sensor. The shield also has a middle position, which is between the shielding position and the exposed position. The second driving component includes an electromagnet and a reset elastic element. The locking block is made of magnetic material. When the electromagnet is energized, it can drive the locking block to disengage from the locking hole. When the electromagnet is de-energized, the reset elastic element can drive the locking block to extend into the locking hole. The locking block has a locking position and a disengaging position. The locking block is located in the locking position, inside the locking hole, in the disengaging position, or outside the locking hole. The shielding component is in the middle position, the locking block is in the disengaging position, and the top surface of the locking block abuts against the bottom surface of the shielding component. The position sensor is used to detect whether the locking block is in the disengaging position.

[0102] The steps in S211 include:

[0103] S2111, control the first drive component to move the baffle to the middle position;

[0104] S2112, Real-time control of the position sensor to detect whether the reset elastic element drives the locking block away from the disengagement position, and control of the first drive component to drive the shield to move to the exposure position;

[0105] S2113, if the card block leaves the disengagement position, then control the first drive component to be powered off;

[0106] And / or,

[0107] The steps in S221 include:

[0108] S2211, control the electromagnet to be energized to attract the card block and disengage it from the card hole;

[0109] S2212, control the first driving component to move the shield to the shielding position, and control the position sensor to detect whether the card block is in the disengagement position;

[0110] S2213, if the locking block is in the disengaged position, then control the electromagnet to be de-energized.

[0111] When the position sensor detects that the locking block has left the disengagement position, it sends this information to the control module. The control module then cuts off power to the first drive component, stopping its operation and preventing it from further moving the shading plate and photovoltaic module to the left. This avoids damage from squeezing between the shading plate and the locking block, and also saves energy from the first drive component. It should be noted that after the position sensor detects the locking block has left the disengagement position, the disengaged block will extend into the locking hole. When the position sensor detects the block has disengaged from the locking hole and moved to the disengagement position, it cuts off power to the electromagnet, thus saving energy.

[0112] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
