Technical Field

[0001] This utility model relates to the field of smart wearable technology, and in particular to a nose pad structure and smart glasses. Background Technology

[0002] With technological advancements, smart glasses have integrated various functional modules to meet diverse user needs. As the functionality of smart glasses continues to increase, the number of electronic components and sensors that need to be housed within the frame is also growing. However, current smart glasses do not offer external air pressure detection. Adding an air pressure detection component would typically place it within the frame, causing it to compete for limited space with other components, leading to functional and structural conflicts. Therefore, adding an air pressure detection component to existing smart glasses requires significant modifications, necessitating a complete redesign of the frame layout, thus increasing design and production costs. Utility Model Content

[0003] The main purpose of this invention is to propose a nose pad structure and smart glasses, which aims to set up an air pressure detection component inside the nose pad. The nose pad can add air pressure detection function to the smart glasses, thereby reducing the need to modify the frame and reducing the design and production costs of adding air pressure detection function.

[0004] To achieve the above objectives, this utility model proposes a nose pad structure for connection with a glasses frame, the nose pad structure comprising:

[0005] Nose pads, used to support the eyeglass frame;

[0006] A connecting component, one end of which is connected to the nose pad and the other end of which is used to connect to the eyeglass frame; and

[0007] A pressure detection component is disposed on the nose pad and is used to detect external air pressure.

[0008] In one embodiment, the nose pad has a cavity and a through hole communicating with the cavity, and the air pressure detection component is disposed in the cavity and detects the external air pressure through the through hole.

[0009] In one embodiment, the air pressure detection component includes:

[0010] A support frame is disposed in the cavity;

[0011] Circuit board, the circuit board being connected to the support frame; and

[0012] A pressure sensor is provided on the circuit board, and the pressure sensor has a detection film, which is positioned opposite the through hole.

[0013] In one embodiment, the nose pad is covered to the outside of the air pressure detection component by an overmolding process.

[0014] In one embodiment, the nose pad has an opening communicating with the cavity, the connecting assembly has a threading channel, one end of the threading channel is communicating with the opening, and the other end of the threading channel is used to connect to the eyeglass frame. The air pressure detection assembly also includes a connecting wire connected to the circuit board, and the connecting wire passes through the opening and the threading channel to be electrically connected to the eyeglass frame.

[0015] In one embodiment, the support frame includes a first frame and a second frame connected at an angle. The first frame is connected to the circuit board, and the second frame is provided with a lead wire groove that passes through the opening. The connecting wire is confined within the lead wire groove.

[0016] In one embodiment, the connecting assembly includes a connecting tube and a mounting base connected together. The connecting tube has the wire passage. The mounting base is connected to one end of the connecting tube and has a groove communicating with the wire passage. The nose pad is rotatably disposed in the groove. The nose pad has an opening communicating with the groove and the cavity. The connecting wire passes through the opening and the groove to extend into the wire passage.

[0017] In one embodiment, the nose pad has an abutting surface and a mounting surface that are opposite to each other. The abutting surface is used to abut against the bridge of the nose, and the mounting surface is connected to the connecting assembly. The through hole is formed on the mounting surface.

[0020] The technical solution of this utility model involves placing the air pressure detection component inside the nose pad. When the nose pad is connected to the frame via a connecting component, the air pressure detection component is also connected to the frame, enabling the smart glasses to have an air pressure detection function. This avoids directly placing the air pressure detection component inside the frame, minimizing changes to the original component design and layout within the frame, and reducing design and production costs.

[0031] In related technologies, the various functional electronic components of smart glasses are usually housed within the frame. Existing smart glasses devices do not provide external air pressure detection functionality. If an air pressure detection component were added, it would typically be placed within the frame. However, this could lead to the air pressure detection component competing for limited space with other components within the frame, resulting in functional and structural conflicts.

[0032] Based on the above issues, please refer to the following: Figures 1 to 3 As shown, this utility model proposes a nose pad structure 100 for connecting with a glasses frame. The nose pad structure 100 includes a nose pad 1, a connecting component 2, and an air pressure detection component 3. The nose pad 1 is used to support the glasses frame. One end of the connecting component 2 is connected to the nose pad 1, and the other end is used to connect with the glasses frame. The air pressure detection component 3 is located on the nose pad 1 and is used to detect external air pressure.

[0033] Specifically, in this embodiment, the air pressure detection component 3 is disposed on the nose pad 1. When the nose pad 1 is connected to the frame via the connecting component 2, the air pressure detection component 3 is also connected as a functional module to the main control module of the frame, enabling the smart glasses to have an air pressure detection function. This avoids directly placing the air pressure detection component 3 inside the frame, avoiding significant changes to the original component design and layout within the frame, and reducing design and production costs. The nose pad 1 is connected to the frame via the connecting component 2, thus maintaining a certain distance between the nose pad 1 and the frame, allowing the frame to have an appropriate wearing height.

[0034] Understandably, the barometric pressure detection component 3 can detect external air pressure in real time, providing the wearer of the smart glasses with accurate air pressure information for reference during travel and activities. Optionally, the barometric pressure detection component 3 can also be connected to an alarm module inside the frame, and the alarm module can be set with maximum and minimum detection values ​​for the barometric pressure detection component 3. When the barometric pressure detection component 3 detects that the external air pressure is higher than the maximum detection value or lower than the minimum detection value, the alarm module will issue an alarm to remind the user to pay attention to safety.

[0035] Optionally, the nose pad 1 is made of silicone or rubber, giving it a certain degree of elasticity. This allows the nose pad 1 to fit snugly against the user's nose bridge, improving the comfort of wearing the smart glasses. It also provides some cushioning protection for the air pressure detection component 3, reducing the possibility of damage to it, and serves as insulation to ensure the reliability of the circuitry of the air pressure detection component 3. Furthermore, the nose pad 1 can have a curved surface to better fit the user's nose bridge, further enhancing wearing comfort.

[0036] In practice, the air pressure detection component 3 can be connected to the outside of the nose pad 1 or located inside the nose pad 1. The air pressure detection component 3 can communicate with the main control module of the frame wirelessly, such as via Bluetooth, or it can be directly connected to the main control module of the frame via the connecting wire 34; no specific limitation is made here.

[0037] In embodiments of this utility model, such as Figures 1 to 3 As shown, the nose pad 1 has a cavity 11 and a through hole 12 connecting the cavity 11. The air pressure detection component 3 is located in the cavity 11 and detects the external air pressure through the through hole 12.

[0038] In this embodiment, the air pressure detection component 3 is disposed within the cavity 11 of the nose pad 1. Thus, the nose pad 1 provides support and protection for the air pressure detection component 3, effectively reducing the risk of failure or damage caused by external impacts, vibrations, or other factors. This ensures the stability and reliability of the air pressure detection component 3 and extends its service life. The air pressure detection component 3 detects external air pressure through the through-hole 12, minimizing the exposed portion of the air pressure detection component 3 and further ensuring its stability and reliability.

[0039] In actual implementation, the through hole 12 is only provided for the detection end of the air pressure detection component 3, so that the through hole 12 is set in a small size. Optionally, a sealing ring can be provided between the through hole 12 and the air pressure detection component 3 to further ensure the sealing of the cavity 11 and prevent water vapor or external impurities from entering the cavity 11 through the through hole 12 and affecting the normal operation of the air pressure detection component 3.

[0040] In embodiments of this utility model, such as Figures 1 to 3As shown, the air pressure detection assembly 3 includes a support frame 31, a circuit board 32, and an air pressure sensor 33. The support frame 31 is located in the cavity 11; the circuit board 32 is connected to the support frame 31; the air pressure sensor 33 is located on the circuit board 32, and the air pressure sensor 33 is provided with a detection film 331, which is positioned opposite the through hole 12.

[0041] In this embodiment, the support frame 31 is the mounting structure in the air pressure detection assembly 3, serving to support and fix the circuit board 32 and the air pressure sensor 33. The circuit board 32 is connected to the support frame 31 and is used to set up signal processing and transmission circuits related to air pressure detection, so as to transmit the detection results of the air pressure sensor 33 to the frame. The air pressure sensor 33 can measure the external air pressure by detecting the deformation of the thin film 331.

[0042] Understandably, the pressure sensor 33 can detect external air pressure by utilizing the pressure difference between the inside and outside of the detection diaphragm 331. When the external air pressure is greater than the internal air pressure of the detection diaphragm 331, the detection diaphragm 331 will deform inward; when the external air pressure is less than the internal air pressure of the detection diaphragm 331, the detection diaphragm 331 will deform outward. The pressure sensor 33 can measure the magnitude of the external air pressure by detecting the deformation of the detection diaphragm 331. In this application, the outer side of the detection diaphragm 331 faces the through hole 12, and a sealed reference pressure chamber can be provided on the inner side of the detection diaphragm 331. Optionally, the outer side of the detection diaphragm 331 can be fitted over the through hole 12, and a sealing ring is provided between the through hole 12 and the detection diaphragm 331. In this way, the cavity 11 can be set as the reference pressure chamber, or the air pressure in the cavity 11 can be set to be the same as the reference air pressure, so as to further ensure the reliability of the detection of the pressure detection component 3. Understandably, the edge of the detection membrane 311 is supported by a bracket. When the detection membrane 311 covers the through hole 12, the bracket of the detection membrane 311 is in close contact with the cavity wall of the cavity 11, or in close contact through a sealing ring, to ensure the sealing of the cavity 11. Optionally, the area of ​​the detection membrane 311 is larger than the area of ​​the through hole 12.

[0043] Optionally, the pressure sensor 33 can be a capacitive pressure sensor 33 or a resistive pressure sensor 33, without any specific limitation.

[0044] Optionally, the circuit board 32 is a flexible circuit board 32. Understandably, the flexible circuit board 32 possesses good flexibility and elasticity, effectively resisting external vibrations and impacts, reducing the risk of circuit connection breakage or damage due to external forces, and improving the reliability and stability of the air pressure detection component 3. At the same time, the flexible circuit board 32 is lightweight and thin, which helps to reduce the weight of the nose pad 1 and improve wearing comfort.

[0045] In embodiments of this utility model, such as Figure 1 and Figure 3As shown, the nose pad 1 is wrapped around the outside of the air pressure detection component 3 using an overmolding process.

[0046] Specifically, the nose pad 1 is coated with adhesive and installed on the outside of the air pressure detection component 3, with a through hole 12 reserved only at the detection end of the air pressure detection component 3, so that the air pressure detection component 3 can detect external air pressure. The adhesive coating of the nose pad 1 can effectively prevent moisture, dust and other impurities from entering the cavity 11, protect the relevant electronic components of the air pressure detection component 3, improve the stability of the air pressure detection component 3, and extend the service life of the air pressure detection component 3. At the same time, it can also effectively ensure the sealing of the cavity 11 and prevent the reference pressure chamber inside the detection diaphragm 331 from failing.

[0047] In embodiments of this utility model, such as Figures 1 to 3 As shown, the nose pad 1 has an opening 17 that connects to the cavity 11, the connecting component 2 has a wire channel 211, one end of the wire channel 211 is connected to the opening 17, and the other end of the wire channel 211 is used to connect to the eyeglass frame. The air pressure detection component 3 also includes a connecting wire 34 connected to the circuit board 32. The connecting wire 34 passes through the opening 17 and the wire channel 211 to be electrically connected to the eyeglass frame.

[0048] In this embodiment, the barometric pressure detection component 3 is electrically connected to the eyeglass frame via a connecting wire 34. One end of the connecting component 2 is connected to the nose pad 1, and the other end is connected to the eyeglass frame. The connecting component 2 has a wire-passing channel 211, providing a connection channel between the circuit board 32 and the electronic components inside the eyeglass frame. The connecting wire 34 is inserted into the eyeglass frame through the wire-passing channel 211 to prevent direct exposure of the connecting wire 34 on the circuit board 32, thus improving the reliability of the electrical connection between the barometric pressure detection component 3 and the eyeglass frame. In this way, the connecting component 2 achieves a mechanical connection with the eyeglass frame while also allowing the connecting wire 34 to be inserted into the eyeglass frame.

[0049] In embodiments of this utility model, such as Figures 1 to 3 As shown, the support frame 31 includes a first frame 311 and a second frame 312 connected at an angle. The first frame 311 is connected to the circuit board 32. The second frame 312 is provided with a lead wire groove 3121 and passes through the opening 17. The connecting wire 34 is limited to the lead wire groove 3121.

[0050] In this embodiment, the first frame 311 is disposed on the side of the circuit board 32 near the opening 17, and the circuit board 32 is connected to the first frame 311. This enhances the mechanical strength of the circuit board 32 and ensures the stability of its shape and position. The second frame 312 passes through the opening 17 and is provided with a lead groove 3121 for the connecting wire 34 to pass through. The second frame 312 is used to guide and restrict the position of the connecting wire 34 within the opening 17, thus relatively fixing the positions of the circuit board 32 and the connecting wire 34 and preventing unstable electrical connection between the connecting wire 34 and the circuit board 32 due to rotation of the nose pad 1. The connection between the first frame 311 and the second frame 312 can be rounded to avoid damage to the circuit board 32 and the connecting wire 34.

[0051] The first frame 311 and the second frame 312 are set at an angle, and the angle between them can be the same as the angle between the extension direction of the cavity 11 and the extension direction of the opening 17. This ensures that the relative position of the circuit board 32 and the connecting wire 34 is consistent with the relative position of the cavity 11 and the opening 17, thus ensuring the stability of the electrical connection between the two. At the same time, the support frame 31 also provides support for the nose pad 1, thereby improving the stability of the nose pad structure 100.

[0052] Optionally, the support frame 31 is made of spring sheet material, which has a certain buffering effect and can return to its original position after deformation, so as to ensure the stability of the relative position of the circuit board 32 and the connecting wire 34 passing through the opening 17.

[0053] Alternatively, the first frame 311 and the circuit board 32 can be connected by adhesive or screws.

[0054] Optionally, the side of the first frame 311 facing away from the circuit board 32 may be provided with protrusions or recesses. When the nose pad 1 is coated with adhesive to the first frame 311, the connection strength between the first frame 311 and the nose pad 1 can be enhanced.

[0055] Understandably, the lead wire groove 3121 is a through groove that runs through both ends, so that the connecting wire 34 can be led out from the circuit board 32 and extend out of the cavity 11 through the lead wire groove 3121 and the opening 17.

[0056] In actual implementation, the connecting wires 34 include multiple wires, and the lead grooves 3121 are arranged one-to-one with the connecting wires 34. Each connecting wire 34 passes through a lead groove 3121, thus avoiding multiple connecting wires 34 from getting tangled together and affecting the stability and reliability of the electrical connection. Optionally, the connecting wires 34 and the lead grooves 3121 can be arranged in one, two, three, or four sets, etc., without specific limitations.

[0057] In embodiments of this utility model, such as Figures 1 to 3As shown, the connecting assembly 2 includes a connecting pipe 21 and a mounting base 22 connected to each other. The connecting pipe 21 is provided with a wire passage 211. The mounting base 22 is connected to one end of the connecting pipe 21 and is provided with a receiving groove 221 that communicates with the wire passage 211. The nose pad 1 is rotatably disposed in the receiving groove 221. The nose pad 1 is provided with an opening 17 that communicates with the receiving groove 221 and the cavity 11. The connecting wire 34 passes through the opening 17 and the receiving groove 221 to extend into the wire passage 211.

[0058] In this embodiment, the connecting tube 21 is hollow to form a wiring channel 211, which protects the connecting wire 34 and prevents it from being directly exposed. The mounting base 22 is used to mount and fix the nose pad 1. The nose pad 1 is located on the side of the mounting base 22 away from the connecting tube 21. The mounting base 22 has a groove 221 that connects to the wiring channel 211. The opening of the groove 221 faces the nose pad 1 and communicates with the opening 17 of the nose pad 1, allowing the connecting wire 34 on the circuit board 32 to be connected to the frame through the opening 17, the groove 221, and the wiring channel 211, thus achieving an electrical connection between the air pressure detection component 3 and the frame. Simultaneously, the nose pad 1 is rotatably mounted within the groove 221, allowing the user to adjust the angle and position of the nose pad 1 according to their wearing needs, improving the comfort of wearing the smart glasses.

[0059] In actual implementation, the nose pad 1 includes a main body 15 and a connecting part 16. The connecting part 16 is confined within the receiving groove 221 and is rotatably connected to the groove wall of the receiving groove 221 via a rotating shaft. The main body 15 is located outside the receiving groove 221 and is used to abut against the user's nose bridge to support the eyeglass frame. The main body 15 is provided with a cavity 11 for accommodating the air pressure detection component 3, and the connecting part 16 is provided with an opening 17 connecting the cavity 11 and the receiving groove 221.

[0060] Alternatively, the main body 15 and the connecting part 16 can be integrally formed, or they can be connected by adhesive or screws.

[0061] Optionally, the connecting tube 21 can be made of metal or plastic, and has a certain plastic deformation capability. Users can slightly change the shape of the connecting tube 21 to adjust the position of the nose pad 1, so that the position of the nose pad 1 is more in line with the position of the bridge of the nose, thereby improving the comfort of wearing smart glasses.

[0062] In embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the nose pad 1 has a contact surface 13 and a mounting surface 14 that are opposite to each other. The contact surface 13 is used to contact the bridge of the nose, and the mounting surface 14 is connected to the connecting component 2. The through hole 12 is opened on the mounting surface 14.

[0063] In this embodiment, the through hole 12 is provided on the mounting surface 14 of the nose pad 1 away from the contact surface 13, so as to avoid the user's nose bridge blocking the through hole 12 when the user wears smart glasses, which would prevent the air pressure detection component 3 from detecting the external air pressure normally.

[0064] In actual implementation, the nose pad 1 is usually flat, with the contact surface 13 and the mounting surface 14 being the two end faces of the nose pad 1, which have a large area. The circuit board 32 in the air pressure detection assembly 3 can be set parallel to the contact surface 13 and the mounting surface 14 to conform to the shape of the nose pad 1 and obtain the optimal setting position.

[0065] Understandably, the nose pad 1 also has a relative upper and lower side and a relative inner and outer side. Here, the upper, lower, inner and outer sides refer to the periphery of the nose pad 1 located between the mounting surface 14 and the abutment surface 13. When the user wears smart glasses, the upper and outer sides are the sides away from the bridge of the nose. The through hole 12 can also be set on the upper and outer sides.

[0066] In embodiments of this utility model, such as Figure 1 As shown, the end of the connecting component 2 away from the nose pad 1 is provided with a slot 212, which is used to engage with the frame.

[0067] Specifically, the end of the connecting component 2 furthest from the nose pad 1 has a slot 212 for connecting to the frame, facilitating the insertion of the nose pad structure 100 into the frame. In actual implementation, the frame has a locking hole communicating with the internal space. The end of the connecting component 2 furthest from the nose pad 1 is inserted into the locking hole, and a locking block inside the locking hole engages with the slot 212 to achieve a limiting position, thereby fixing the connecting component 2 to the frame and achieving a mechanical connection between the nose pad structure 100 and the frame. Simultaneously, the wiring channel 211 also communicates with the interior of the frame, allowing the connecting wire 34 to be connected to the electrical structure inside the frame, achieving an electrical connection between the nose pad 1 component and the frame.

[0068] Optionally, the connecting component 2 may also be provided with an electrical connector, such as an electrical connection pin, electrical connection terminal, or Type-C connector, at the end away from the nose pad 1. The electrical connector is electrically connected to the air pressure detection component 3, and the eyeglass frame is provided with an electrical connection interface. When the electrical connector is inserted into the electrical connection interface of the eyeglass frame, the mechanical connection and electrical connection between the connecting component 2 and the eyeglass frame can be completed simultaneously.

[0069] Optionally, the end of the connecting component 2 away from the nose pad 1 can also be detachably connected to the frame by means of screws or clips, so as to facilitate user repair or replacement of the nose pad structure 100.

[0070] This utility model also proposes a smart glasses, which includes a frame and a nose pad structure 100. The specific structure of the nose pad structure 100 is as described in the above embodiments. Since the nose pad structure 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The nose pad structure 100 is connected to the frame, and the air pressure detection component 3 is connected to the frame, enabling the smart glasses to have an air pressure detection function. The smart glasses can be AR glasses, VR glasses, etc. The above description is only an exemplary embodiment of this utility model and does not limit the patent scope of this utility model.
