In addition, the nose pads of smart wearable devices have a single function, which can only provide support and cannot enrich the user's wearing experience. Summary of the Invention

[0003] In view of the above problems, the purpose of this invention is to provide a nose pad module and a smart wearable device to solve the problems of limited functionality caused by size limitations in existing smart wearable devices.

[0006] The heart rate detection component is used to send detection signals to the skin of the wearer of the nose wing module and to receive the reflected signals reflected back from the skin.

[0007] The wearer's heart rate information is determined based on the detected signal and the reflected signal.

[0008] Alternatively, an optional technical solution is that the heart rate detection component includes a light source and photodiodes respectively disposed on both sides of the light source; wherein,

[0009] The light source is used to emit light to detect signals onto the skin, and the photodiode is used to detect the light reflection signal reflected back from the skin and convert the light reflection signal into an electrical signal;

[0010] The nose module determines the wearer's heart rate information based on the electrical signal.

[0011] Alternatively, an optional technical solution is that the module bracket includes a fixing part and an adjusting part movably connected to the fixing part; wherein,

[0012] A support plate is provided on the adjustment part, and the circuit board is attached and fixed on the support plate;

[0013] A soft rubber nose pad is provided on the support plate, and the soft rubber nose pad covers the circuit board and the heart rate detection component.

[0014] Alternatively, an optional technical solution is to provide a light source lens on one side of the light source and a detection lens on one side of the photodiode; wherein,

[0015] The size of the light source lens is not less than the size of the light source, and the size of the detection lens is not less than the size of the photodiode.

[0036] To provide a detailed description of the nose pad module and smart wearable device of the present invention, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] Figures 1 to 3 The overall or partial schematic structure of the nose pad module according to embodiments of the present invention is shown from different angles.

[0038] like Figures 1 to 3 As shown in the figure, the nose pad module of this invention includes a connecting bracket and nose wing modules symmetrically arranged at both ends of the connecting bracket. The two nose wing modules are symmetrically distributed at both ends of the connecting bracket and adapted to the user's nose position. Each nose wing module further includes a module bracket, a circuit board 6 disposed on the module bracket, and a heart rate detection component disposed on the circuit board 6. The heart rate detection component can send a detection signal to the wearer's skin and receive the reflected signal reflected back from the skin, thereby determining the wearer's heart rate information based on the detection signal and the reflected signal. Since the heart rate detection component is located inside the nose pad module and can directly contact the user's skin, it can enrich the functions of the nose pad module while reducing the impact of external interference on the detection results and improving the accuracy of heart rate detection.

[0039] The heart rate detection component includes a light source 8 and photodiodes 71 and 72 respectively disposed on both sides of the light source 8. The light source 8 emits light to the skin to detect signals, and the photodiodes detect the reflected light signals from the skin and convert them into electrical signals, which are then sent to the processing circuit. This enables the detection of the user's heart rate and provides timely prompts and warnings based on the detection results. The accuracy of heart rate detection is improved by comparing or averaging the reflected signals picked up by the first photodiode 71 and the second photodiode 72.

[0040] Specifically, the light source 8 can be an LED or a laser, which can emit light waves of a certain wavelength toward the wearer's skin. Since the absorption rate of light by the user's blood vessels and other tissues varies during the pulse, the light reflected back after the detection signal generated by the light source 8 passes through the skin will be different. At this time, the reflected signal can be received by a photodiode and converted into an electrical signal. The user's heart rate can be determined based on the electrical signal.

[0041] Furthermore, since the nose pad module is located on the bridge of the user's nose when the user wears the smart wearable device, and the bridge of the nose vibrates when the user speaks, the nose pad module of this invention can also include a VPU 11 (Voice Pick-up Unit) on the circuit board 6. This VPU 11 is a MEMS device that captures voice signals through bone conduction and has advantages such as low power consumption, small size, and high performance. By placing the VPU 11 on the back of the heart rate detection component, that is, the VPU 11 and the heart rate detection module are located on opposite sides of the circuit board 6, it is possible to achieve high-precision voice pickup while detecting the user's heart rate, further enriching the user experience.

[0042] In one specific embodiment of the present invention, the module support includes a fixing part 2 and an adjusting part movably connected to the fixing part 2. The adjusting part is movably connected to the fixing part 2 via a rotating shaft. After the user wears the nose pad module, the angle of the adjusting part can automatically adapt to the position of the wearer's nose. A support plate 5 is provided on the adjusting part, and a circuit board 6 is attached and fixed to the support plate 5. A soft rubber nose pad 1 is provided on the support plate 5, covering the circuit board 6 and the heart rate detection component. The soft rubber nose pad 1 can be molded and then fitted onto the support plate 5 and the circuit board 6, or it can be directly injection molded onto the support plate 5 and the circuit board 6. The present invention does not specifically limit the formation method of the soft rubber nose pad 1. Furthermore, in addition to the movably connected fixing and adjusting parts, the module support can also adopt an integrated support structure. This integrated module support can be directly formed on the outside of the support plate 5 and the circuit board through fluidized bed coating.

[0043] To further improve the detection accuracy of the heart rate detection component, reduce external interference, and ensure the wearing comfort of the nose pad module, a light source lens 10 can be set on one side of the light source 8, and a detection lens, including a first detection lens 91 and a second detection lens 92, can be set on the other side of the photodiode. The size of the light source lens 10 is not smaller than the size of the light source 8, and the size of the detection lens is not smaller than the size of the corresponding photodiode. The light source lens 10 and the detection lens are embedded in the soft rubber nose pad 1. Alternatively, each lens can be confined within the soft rubber during the injection molding process of the soft rubber nose pad 1. The light source 8 can directly emit light from the soft rubber nose pad 1 through the light source lens 10 to reach the wearer's skin. Then, the signal reflected back from the skin is fed back to the photodiode through the detection lens to complete the detection of the heart rate signal.

[0044] The soft rubber nose pad 1 is made of an opaque color, such as black or other dark colors, to achieve a light-blocking effect through the soft rubber, thereby reducing the influence of external light on the detection signal.

[0045] In addition, a driving circuit can be set on the circuit board 6. This driving circuit controls the light intensity and timing of the light source 8. In different application scenarios, such as those with significant differences in ambient light, the light intensity and timing of the light source 8 can be adjusted to achieve different levels of heart rate detection accuracy. For example, if abnormalities or fluctuations in the user's heart rate are detected, the light intensity and timing of the light source 8 can be automatically increased to improve detection accuracy.

[0046] In another specific embodiment of the present invention, the nose bridge module further includes a guide tube 3 disposed on the fixing part 2 and a guide wire 4 located within the guide tube 3. The circuit board 6 is electrically connected to the connecting bracket via the guide wire 4. The nose wing module may include a left nose wing module and a right nose wing module, which are detachably electrically connected to the connecting bracket. This detachable electrical connection can be achieved through an external conduit, a guide wire located within the external conduit, and a corresponding connector. For example, a connector can be provided at the end of the external conduit, and a detachable connection can be made with the connecting bracket via the connector.

[0047] In another invention, the present invention also provides a smart wearable device, including the aforementioned nose pad module. It should be noted that embodiments of the smart wearable device can be found in the descriptions of the nose pad module embodiments, and will not be repeated here.

[0048] According to the nose pad module and smart wearable device of the present invention, a heart rate detection component and a VPU are set in the nose wing module. During the user's wearing of the nose pad, the heart rate detection component can detect the wearer's skin blood information and determine the user's heart rate accordingly. Since the nose pad is in direct contact with the skin, the influence of external interference sources can be reduced, and the detection accuracy is high. In addition, the VPU can also realize the acquisition of voice signals, which can enrich the function of the nose pad module and reserve more design space for other structural components of the smart wearable device, such as temples and frames, to meet the user's demand for higher performance.

[0049] The nose pad module and smart wearable device according to the present invention have been described above by way of example with reference to the accompanying drawings. However, those skilled in the art should understand that various modifications can be made to the nose pad module and smart wearable device proposed in the present invention without departing from the scope of the invention. Therefore, the scope of protection of the present invention should be determined by the content of the appended claims.
