The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0046] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides various specific processes and examples of materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0047] Hereinafter, with reference to the accompanying drawings, a sensor assembly 1 for a wearable device 100 according to an embodiment of the first aspect of the present invention will be described.

[0048] See also Figure 1-Figure 3 The sensor assembly 1 can be used in a wearable device 100. The sensor assembly 1 includes: a housing 11, a cover 12 and a main board 16. The housing 11 includes a mounting portion 111, and the mounting portion 111 has a hollow area 1110. The cover 12 is arranged on the mounting portion 111, and the cover 12 has a light-transmitting portion 121 and an electrode portion 122. The cover 12 is connected to the housing 11 and the connection is sealed. The main board 16 is arranged on the back side of the cover 12, and the main board 16 is connected to the housing 11 and the connection is sealed. The main board 16 includes a flexible circuit board 13 and a reinforcement plate 14. The flexible circuit board 13 includes a carrier plate portion 131. The reinforcement plate 14 is arranged on the side of the carrier plate portion 131 facing away from the cover plate 12. The side of the carrier plate portion 131 facing the cover plate 12 is provided with a conductive member 132, a photosensitive component 133 and a chip 134. The conductive member 132 is electrically connected to the electrode portion 122 through the hollow area 1110, and the photosensitive component 133 is opposite to the light-transmitting portion 121 through the hollow area 1110.

[0049] Exemplarily, the light sensing component 133 may include a light source 1331 and a photosensitive element 1332. The light source 1331 (such as an LED) emits light, and the light is refracted through the skin and received by the photosensitive element 1332 (such as a PD). The photosensitive element 1332 transmits the signal to the chip 134. After analysis and calculation, the chip 134 can obtain information such as blood oxygen, electrocardiogram, and heart rate, thereby realizing health detection.

[0050] The two sides of the cover plate 12 in the thickness direction are the front side and the back side, wherein the side of the cover plate 12 facing the user is the front side, and the other side (i.e., the side facing away from the user) is the back side. Exemplarily, the front side surface of the cover plate 12 can be an outward convex surface, so as to facilitate the contact between the electrode part 122 and the user's skin to achieve electrical signal detection.

[0051] Among them, the cover plate 12 is connected to the shell 11 and the connection is sealed, and the main board 16 is connected to the shell 11 and the connection is sealed, so that the connection between the cover plate 12 and the shell 11 and the connection between the main board 16 and the shell 11 are both sealed, so that the sensor component 1 has self-sealing properties, effectively preventing external factors such as dust and moisture from interfering with and damaging the internal circuit of the sensor component 1, thereby improving the reliability and service life of the sensor component 1.

[0052] In the embodiments of the present application, "the cover plate 12 is connected to the shell 11 and the connection is sealed" and "the main board 16 is connected to the shell 11 and the connection is sealed". The specific sealing method is not limited. For example, it can be using sealant, sealing ring or sealing structure, etc., and advanced sealing technology such as laser welding or ultrasonic welding can also be considered to improve the reliability and efficiency of sealing.

[0053] Among them, the light-transmitting portion 121 and the electrode portion 122 arranged on the cover plate 12 are respectively opposite to the photosensitive component 133 and the conductive member 132 on the flexible circuit board 13, which reduces the loss and interference during signal transmission and ensures the accurate transmission of optical signals and the stable connection of electrical signals.

[0054] The provision of the reinforcing plate 14 enhances the overall structural strength of the flexible circuit board 13, prevents deformation or damage caused by excessive force on the flexible circuit board 13, and improves the durability and stability of the sensor assembly 1. For example, the reinforcing plate 14 can be made of different materials, such as metal, plastic or composite materials, to meet different strength, weight and cost requirements; the structure of the reinforcing plate 14 can be designed in various shapes and sizes to adapt to different flexible circuit board 13 layout and installation requirements.

[0055] The electrical connection method in "the conductive member 132 is electrically connected to the electrode portion 122 through the hollow area 1110" is not limited, for example, it can be welding, plugging or crimping, etc., and reliable connection methods such as elastic contacts can also be considered to meet the connection requirements of the flexible circuit board 13 when it is bent. It is understandable that considering environmental factors such as vibration and impact of the wearable device 100, the connection method has a certain ability to resist vibration and impact.

[0056] Exemplarily, the shell 11 can be made of different materials, such as metal, plastic or ceramic, to meet different strength, weight and corrosion resistance requirements; the structure of the shell 11 can be designed into various shapes and sizes to adapt to different wearable device 100 application scenarios and user needs.

[0057] In the above technical solution, the mainboard 16 of the sensor assembly 1 is designed to use a flexible circuit board 13 to carry the conductive member 132, the light sensing member 133 and the chip 134, and the conductive member 132, the light sensing member 133 and the chip 134 are all arranged on one side of the flexible circuit board 13, so that the overall thickness of the sensor assembly 1 is relatively thin. Moreover, by setting the connection between the cover plate 12 and the housing 11, and the connection between the mainboard 16 and the housing 11 to be sealed, the sensor assembly 1 has self-sealing properties, which effectively prevents external factors such as dust and moisture from interfering with and damaging the internal circuit of the sensor assembly 1. In this way, since the sensor assembly 1 is thin and self-sealing, the setting position can be flexibly selected in the wearable device 100 to improve the wearing comfort.

[0058] Some flexible wearable devices in the related technology are equipped with a health sensing structure for detecting health status. Because flexible wearable devices are equipped with batteries, motherboards and other structures, they need to reserve a part of the straight board area. The straight board area has a stable structure and the outer shell can be completely sealed. Therefore, the health sensing structure is usually designed in the straight board area. However, with the diversification of the forms of flexible wearable devices, the area of ​​a single straight board area is getting smaller and smaller, which makes it difficult to meet the installation requirements of the health sensing structure.

[0059] During the research and development process, we considered designing the health sensor structure in the bending area of ​​the flexible wearable device. However, since there is a moving mechanism in the bending area, the shell of the bending area cannot be sealed. When designing the health sensor structure in the bending area, an additional sealing structure is required to ensure waterproof and dustproof requirements.

[0060] The health sensing structure in the related technology is composed of a cover plate, a shell, a PCB board, a photosensitive component, a chip, etc. The front of the PCB board is provided with a photosensitive component, and the back of the PCB board is provided with a chip and a connector. The PCB board is connected to the flexible circuit board through the connector, and the flexible circuit board is connected to the main board of the flexible wearable device. The normal health sensing structure height is: the sum of the cover plate thickness, the minimum detection distance of the photosensitive component, the height of the photosensitive component, the PCB thickness, the connector height, and the height of the seal (such as a shielding cover or a sealing steel plate).

[0061] In the embodiment of the present application, the main board 16 of the sensor assembly 1 is designed to use a flexible circuit board 13 to carry the conductive member 132, the light sensing component 133 and the chip 134, that is, the FPC base is used. By arranging all the electronic components on the front of the FPC, the thickness of the chip and the connector on the back of the FPC is omitted. The FPC back has a reinforcing plate 14 to ensure strength, and the height of the seal on the back of the PCB (such as a shielding cover or a sealing steel plate) is omitted, so that the overall height of the sensor assembly 1 is significantly reduced, for example, the thickness can be reduced by about 1.3mm. Moreover, due to the use of a flexible circuit board 13, the flexible circuit board 13 can directly extend the wiring part 135 to connect with the main board of the flexible wearable device, so that the connector can be eliminated, saving the space and cost of the connector. Moreover, according to the sensor assembly 1 of the embodiment of the present application, the cover plate 12 is connected to the housing 11 and the connection is sealed, and the main board 16 is connected to the housing 11 and the connection is sealed, which effectively ensures the waterproof and dustproof capabilities of the front and back of the sensor assembly 1.

[0062] In this way, since the sensor component 1 is thin and self-sealing, the setting position in the wearable device 100 can be flexibly selected, so that the wearable device 100 can increase the display area, make the appearance of the wearable device 100 changeable, and provide a variety of forms to meet the needs of different consumers.

[0063] According to the sensor component 1 of the embodiment of the present application, due to its thin thickness and self-sealing properties, the sensor component 1 can be set in the deformable area 22 (such as a bending area or a flexible area) of the wearable device 100. When the wearable device 100 has multiple deformable areas 22, one or more deformable areas 22 can be selected as the installation position of the sensor component 1 to meet diverse design requirements. For example, the sensor component 1 can be set in areas such as a strap or a bracelet to save space on the entire device.

[0064] Flexible wearable devices in related technologies are divided into straight areas and deformable areas (such as bending areas and / or flexible areas). The bending areas have various motion mechanisms such as hinges and gears, and the flexible areas include structures such as bracelets and straps. It is impossible to ensure that the shell is completely sealed in all forms and has no waterproof and dustproof functions. The health sensor structure needs to contact the skin, and the related physiological signals are very weak. Components such as chips are also easily affected by moisture and fail, so the requirements for waterproof and dustproof are very high. If the waterproof and dustproof structure is added separately to the location where the health sensor structure is set, the thickness will be increased, resulting in the health sensor structure convex platform being too high, affecting the consumer's wearing comfort. Therefore, the flexible wearable devices in related technologies all fix the health sensor structure in the straight area. With the diversification of the form of flexible wearable devices and the changes in wearing methods, the area of ​​a single straight area is getting smaller and smaller, and the health sensor needs to contact the skin, so it is best designed in the center. If it is forcibly designed in the straight area, it will have higher requirements for consumers to wear.

[0065] According to the sensor assembly 1 of the embodiment of the present application, due to its thin thickness and self-sealing property, the sensor assembly 1 can be set in the deformable area 22 (such as the bending area or the flexible area) of the wearable device 100. When the outer shell of the bending area or the flexible area cannot be completely sealed, it can automatically meet the waterproof and dustproof requirements without additionally increasing the height, thereby being able to cope with more varied wearing methods of consumers. In short, the sensor assembly 1 according to the embodiment of the present application has independent waterproof and dustproof functions and is thin in thickness, which can increase the wearing comfort of consumers and save space for the straight panel area of ​​the whole device.

[0066] In some implementations, see Figure 4 and Figure 5 The mounting portion 111 includes a penetrating opening area 1111 and a dividing rib 1112 disposed in the opening area 1111. The opening area 1111 is divided into a plurality of hollow areas 1110 by the dividing rib 1112. The photosensitive component 133 includes a light source component 1331 and a photosensitive component 1332. The conductive component 132, the photosensitive component 1332 and the light source component 1331 are respectively disposed corresponding to different hollow areas 1110.

[0067] Thus, the housing 11 divides the opening area 1111 into a plurality of hollow areas 1110 by providing the separation ribs 1112, thereby realizing an orderly layout of the components inside the sensor assembly 1. Each hollow area 1110 corresponds to a different component, and the functional divisions between the components are more clearly defined, thereby reducing signal interference and light interference between each other, and improving the reliability of the sensor assembly 1. At the same time, there is no need to provide additional sponge parts for separation, thereby reducing parts, simplifying assembly, improving assembly efficiency of the sensor assembly 1, and reducing the cost of the sensor assembly 1.

[0068] In addition, the provision of the separation ribs 1112 not only serves to divide the hollow area 1110 , but also enhances the structural strength of the mounting portion 111 , thereby improving the impact resistance of the sensor assembly 1 .

[0069] For example, the separation ribs 1112 can be designed to be straight, curved or irregular in shape to accommodate different shapes of the opening area 1111 and component layout requirements. The number of the separation ribs 1112 can be adjusted as needed to divide an appropriate number of hollow areas 1110 .

[0070] It is worth noting that the number and position distribution of the hollow areas 1110 can be flexibly adjusted according to different wearable devices 100 and application scenarios to meet different needs.

[0071] For example, the layout of the hollow areas 1110 can be evenly distributed, or can be designed into different shapes and sizes as needed to adapt to the size and layout requirements of different components. The spacing between the hollow areas 1110 can be adjusted according to the barrier requirements between the components.

[0072] In some embodiments, see Figure 6-Figure 8 The cover plate 12 includes a transparent substrate 123, the edge of the transparent substrate 123 is coated with a metal electrode 124, the metal electrode 124 constitutes an electrode portion 122, the metal electrode 124 extends from the front side of the transparent substrate 123 to the back side of the transparent substrate 123, and at least a portion of the metal electrode 124 extending to the back side of the transparent substrate 123 is opposite to the conductive member 132; the back side of the transparent substrate 123 is entirely covered with a light shielding layer 125, and the light shielding layer 125 is provided with a first window 1251 at a location corresponding to the conductive member 132, the conductive member 132 is a spring and is electrically connected to the metal electrode 124 at the back side of the transparent substrate 123 through the first window 1251, the photosensitive component 133 includes a light source component 1331 and a photosensitive component 1332, the light shielding layer 125 is provided with a second window 1252 at locations corresponding to each light source component 1331 and each photosensitive component 1332, and the transparent substrate 123 constitutes a light-transmitting portion 121 at a location corresponding to the second window 1252.

[0073] There is at least one light source component 1331 and at least one photosensitive component 1332. Each light source component 1331 is provided with a second window 1252, which means that each light source component 1331 corresponds to a second window 1252, and each photosensitive component 1332 is provided with a second window 1252, which means that each photosensitive component 1332 corresponds to a second window 1252.

[0074] In the above technical solution, by integrating the metal electrode 124 and the light-shielding layer 125 on the transparent substrate 123 and reserving windows for the conductive member 132 and the light-sensing component 133 on the light-shielding layer 125 , a high degree of integration of the cover 12 is achieved, which is beneficial to the miniaturization of the sensor component 1 .

[0075] Among them, the conductive member 132 is a spring and is electrically connected to the metal electrode 124 on the back of the transparent substrate 123 through the first window 1251, and the photosensitive component 133 is arranged corresponding to the light-transmitting portion 121 through the second window 1252, thereby ensuring the electrical signal transmission and optical signal receiving functions of the sensor component 1.

[0076] The light shielding layer 125 is provided with a second window 1252 corresponding to the light sensing component 133, and the transparent substrate 123 forms a light-transmitting portion 121 corresponding to the second window 1252, ensuring that the light emitted by the light source 1331 can irradiate the human skin, thereby improving the transmission efficiency of the light signal; the design of the light shielding layer 125 effectively reduces the interference of external light on the light receiving by the light sensing component 1332, thereby improving the accuracy and sensitivity of the light sensing component 133. In addition, the light shielding layer 125 can also shield the electronic components on the front of the carrier plate portion 131.

[0077] The design of the cover plate 12 is convenient for manufacturing and assembly, thus reducing production costs and improving production efficiency; the electrical connection between the spring and the metal electrode 124 is simple and reliable, and is easy to realize automated production.

[0078] For example, in addition to the spring, the conductive part 132 may also be made of conductive elements of other shapes, such as needle-shaped, sheet-shaped or column-shaped, to meet different installation and connection requirements; the material of the conductive part 132 may be selected from metals, alloys or conductive plastics, to meet different conductive performance and cost requirements.

[0079] Exemplarily, the shading layer 125 can be designed to have different shapes and thicknesses to meet different optical performance and structural strength requirements; in addition to using shading materials, it is also possible to consider using reflective materials or filter materials to further optimize the optical performance.

[0080] Exemplarily, the transparent substrate 123 can be made of different materials, such as sapphire glass, plastic or composite materials, to meet different transparency, strength and cost requirements; the shape and size of the transparent substrate 123 can be adjusted according to the appearance and functional requirements of the wearable device 100.

[0081] Exemplarily, the layout of the electrode portion 122 and the light-transmitting portion 121 can be adjusted according to the layout of the light-sensing component 133 and the conductive member 132 to achieve better signal transmission and reception effects.

[0082] Exemplarily, the transparent substrate 123 is sapphire glass, and its shape is designed to be an oblong. The edges of the front and back sides of the transparent substrate 123 are plated with copper as metal electrodes 124. The metal springs on the flexible circuit board 13 are electrically connected to the metal electrodes 124, so that the electrical signals on the skin can be transmitted to the chip 134. The back side of the transparent substrate 123 is sprayed with light-shielding ink as a light-shielding layer 125, leaving only the first window 1251 and the second window 1252. The second window 1252 allows the light to be more concentrated so that the light-sensing component 133 is not easily disturbed. The first window 1251 allows the metal spring to directly contact the copper plating on the back side. The light-shielding ink can also shield the electronic components on the front side of the flexible circuit board 13.

[0083] In some embodiments, see Figure 2 and Figure 4 The photosensitive component 133 includes a light source component 1331 and a photosensitive component 1332 . The photosensitive components 1332 are multiple and are arranged around the light source component 1331 at intervals. The multiple photosensitive components 1332 are arranged corresponding to different hollow areas 1110 ; the electrode part 122 is arranged around the light-transmitting part 121 .

[0084] Thus, by providing a plurality of photosensitive members 1332 and surrounding the light source member 1331 at intervals, it is possible to receive and detect light emitted by the light source member 1331 in different directions. This layout improves the comprehensiveness and accuracy of light signal detection, so that the sensor assembly 1 can more accurately collect light signals emitted by the light source member 1331 and reflected by the human body.

[0085] The number, position and spacing of the photosensitive members 1332 can be adjusted according to actual needs to meet the requirements of different application scenarios.

[0086] The electrode portion 122 is arranged around the light-transmitting portion 121 . This layout not only facilitates the electrical connection between the electrode portion 122 and the conductive member 132 , but also helps to improve the connection stability and reliability between the electrode portion 122 and the conductive member 132 .

[0087] The layout and setting of the light source component 1331 and the photosensitive component 1332, such as the light emitting angle of the light source component 1331 and the receiving angle of the photosensitive component 1332, can be set as needed to optimize the transmission and reception effects of the optical signal and improve the performance of the sensor component 1.

[0088] In some embodiments, see Fig. 9 and Figure 4The carrier plate portion 131 is formed into a rectangular, elliptical, or oblong structure. The photosensitive component 133 includes a light source 1331 and a photosensitive member 1332. The light source 1331 is arranged in the center of the carrier plate portion 131. There are four photosensitive members 1332 and they are arranged around the light source 1331. The chip 134 is arranged near one end of the length of the carrier plate portion 131 and is located between two adjacent photosensitive members 1332.

[0089] Therefore, by designing the carrier plate portion 131 into a rectangular, elliptical or oblong structure, the front side of the carrier plate portion 131 has a larger layout space, which is conducive to arranging the chip 134 and the photosensitive component 133 on the front side of the carrier plate portion 131. This design of the carrier plate portion 131 frees up space for wiring on the front side of the carrier plate portion 131.

[0090] In addition, the carrier plate portion 131 adopts a rectangular, elliptical or oblong structure, which is easy to process and manufacture during the manufacturing and assembly process, improves the yield rate and reduces the processing cost. Of course, the present application is not limited to this, and other elongated structures close to rectangular, elliptical or oblong structures are also possible, such as an elongated hexagon, an elongated octagon, etc.

[0091] In the above technical solution, by arranging the light source component 1331 at the center of the carrier plate portion 131 and surrounding it with four photosensitive components 1332 , it helps to improve the accuracy and consistency of light signal reception, thereby enhancing the overall performance of the photosensitive component 133 .

[0092] For example, Figure 4 As shown, the carrier plate portion 131 is formed into an oblong structure, the light source member 1331 is arranged in the center of the oblong carrier plate portion 131, the light source member 1331 is close to a square, the two sides of the light source member 1331 are respectively parallel to the two straight sides of the oblong structure, the photosensitive member 1332 is close to a rectangle, the four photosensitive members 1332 arranged around the light source member 1331 are located outside the four vertex corners of the light source member 1331, and the long sides of the photosensitive members 1332 face the light source member 1331. This arrangement and the arrangement angle of the photosensitive members 1332 ensure the accuracy and consistency of the light signal reception, and increase the accuracy of the detection of the sensor assembly 1. It can be understood that the oblong is a runway shape, which is composed of a rectangle and two semicircles.

[0093] In some embodiments, see Figure 3, the mounting portion 111 is a rubber-coated molded part and is connected to the cover plate 12 by rubber coating, so that the connection between the cover plate 12 and the housing 11 is sealed. That is, the mounting portion 111 can be directly obtained by rubber coating process, and the mounting portion 111 is connected to the cover plate 12, so that the connection between the cover plate 12 and the housing 11 can be sealed, effectively preventing external moisture, dust or other impurities from entering the interior of the housing 11 through the connection gap, thereby protecting the electronic components or other sensitive components inside the housing 11 from damage. Moreover, this processing method has high production efficiency. In short, the housing 11 and the front cover plate 12 are fixed together by rubber coating process to ensure the sealing of the front of the sensor assembly 1. Moreover, since the mounting portion 111 is a rubber-coated molded part, the mounting portion 111 can be an insulating material, such as plastic (such as PC, nylon fiber), so that the insulation between the mounting portion 111 and the cover plate 12 can be ensured.

[0094] In some embodiments, see Figure 5 The housing 11 includes a bottom shell portion 112, which is a metal part, and the mounting portion 111 is connected to the bottom shell portion 112 by rubber coating. Therefore, the bottom shell portion 112 is made of metal, which can provide good structural strength and electromagnetic shielding effect, protect the internal electronic components from external electromagnetic interference, and improve the working reliability of the sensor assembly 1.

[0095] Exemplarily, the bottom shell portion 112 is made of metal, such as aluminum alloy, stainless steel, etc., to ensure the strength and reliability of the sensor assembly 1. Exemplarily, the mounting portion 111 is made of plastic, such as PC, nylon fiber, etc. Exemplarily, when the shell 11 is formed, the metal bottom shell portion 112 is first processed, and the cover plate 12 is connected to the metal bottom shell portion 112 through a plastic encapsulation process, and the encapsulated mounting portion 111 is obtained, which can ensure the overall strength of the shell 11, and the insulation and sealing between the cover plate 12 and the bottom shell portion 112 can be ensured, and the waterproof and dustproof capabilities of the sensor assembly 1 can be ensured.

[0096] In some embodiments, see Figure 3 and Figure 5 The mounting portion 111 has a recessed platform 1113, which is annular and surrounds the hollow area 1110, and the cover plate 12 is embedded in the platform 1113. The platform 1113 is annular and surrounds the hollow area 1110, which means that all the hollow areas 1110 are located in the inner ring area of ​​the platform 1113.

[0097] The mounting portion 111 has a recessed platform 1113, which provides a precise positioning reference for the cover plate 12, so that the cover plate 12 can be accurately aligned and embedded during installation, thereby improving the convenience and stability of the installation of the cover plate 12. At the same time, the edge of the platform 1113 can be used as a limiting surface for the cover plate 12, thereby enhancing the connection strength between the cover plate 12 and the mounting portion 111. When the cover plate 12 is embedded in the platform 1113, a compact fit can be formed between the two, which can reduce space occupation on the one hand, and facilitate the formation of a sealed fit between the two on the other hand, which can effectively prevent moisture, dust and other external substances from invading the interior of the housing 11, thereby improving the sealing and waterproof performance of the product.

[0098] In addition, when the mounting portion 111 is a rubber-coated molded part and the mounting portion 111 includes a separation rib 1112, the separation rib 1112 is also formed by rubber-coating, thereby facilitating the processing and forming of the separation rib 1112. In addition, when the mounting portion 111 is a rubber-coated molded part and the mounting portion 111 includes a sink 1113, the sink 1113 is also formed by rubber-coating, thereby facilitating the processing and forming of the sink 1113.

[0099] In some embodiments, see Figure 2 and Figure 3 The mounting portion 111 has a supporting portion 1114 protruding in a direction away from the cover plate 12 , and the edge of the carrier plate portion 131 is connected to the supporting portion 1114 via a double-sided adhesive tape 15 .

[0100] In the above technical solution, the support portion 1114 is provided to provide the shell 11 with a support structure for fixing the flexible circuit board 13, thereby simplifying the structure of the sensor assembly 1 and facilitating the assembly of the flexible circuit board 13. Moreover, the overall rigidity and stability of the shell 11 are enhanced to prevent deformation or damage of the shell 11 due to external force.

[0101] In some embodiments, see Figure 3 The reinforcing plate 14 is connected to the carrier plate portion 131 , and a sealant is provided at the joint between the main board 16 and the shell 11 to seal the joint between the main board 16 and the shell 11 .

[0102] In the above technical solution, the reinforcement plate 14 is connected to the carrier plate portion 131, and a sealant is provided at the fitting position of the main board 16 and the shell 11, so that the connection between the main board 16 and the shell 11 can be realized and the connection is sealed. The reinforcement plate 14 can effectively provide support force to the carrier plate portion 131, and the sealant can effectively fill the gap between the main board 16 and the shell 11 to prevent the intrusion of external substances such as moisture and dust, thereby improving the sealing performance of the entire structure and improving the moisture-proof, dust-proof or corrosion-proof performance of the sensor component 1; the enhancement of the sealing performance can also reduce circuit failures caused by environmental factors, thereby improving the reliability and stability of the sensor component 1.

[0103] In some embodiments, see Figure 2 The reinforcing plate 14 is a metal plate, so that it can have good supporting strength, so that the reinforcing plate 14 can effectively provide supporting force to the carrier plate portion 131.

[0104] Exemplarily, the reinforcing plate 14 is a steel plate, the back of the flexible circuit board 13 is fixed with the steel plate, and the gap between the steel plate and the shell 11 is filled with UV glue as a sealant to ensure the sealing of the back of the shell 11; the flexible circuit board 13 is adhered to the shell 11 by a waterproof double-sided tape 15, and the edge is sealed with the shell 11 by the above-mentioned UV glue.

[0105] Exemplarily, the reinforcing plate 14 and the carrier plate portion 131 may be adhered by means of a waterproof double-sided adhesive tape, or may be fixedly connected by means of fasteners or the like.

[0106] In an embodiment of the present application, the strength and rigidity of the flexible circuit board 13 can be enhanced by adjusting the thickness of the reinforcement plate 14 or changing the shape or material of the reinforcement plate 14; in addition, in other embodiments of the present application, additional sealing structures such as sealing grooves, sealing lips, etc. can be added between the reinforcement plate 14 and the shell 11 to further improve the sealing performance.

[0107] Next, a wearable device 100 according to an embodiment of the second aspect of the present invention is described.

[0108] See also Figure 1 The wearable device 100 includes a device body 2 and a sensor assembly 1 for the wearable device 100 according to any embodiment of the first aspect of the present invention, wherein the sensor assembly 1 is disposed on the device body 2 and combined with Fig. 9 and Figure 4 The flexible circuit board 13 also includes a wiring portion 135 , which extends outside the housing 11 and is connected to the main board of the device body 2 .

[0109] According to the wearable device 100 of the embodiment of the present invention, by setting the sensor component 1 for the wearable device 100 of the first aspect mentioned above, since the sensor component 1 is thin and self-sealing, the sensor component 1 can flexibly select the installation position, for example, it can be set in the deformable area 22 of the wearable device 100, to meet the user's personalized needs and improve the user's experience.

[0110] In some embodiments, see Figure 1The device body 2 has a deformable region 22, the deformable region 22 includes a flexible region and / or a bending region, and the sensor assembly 1 is arranged in the deformable region 22. The deformable region 22 may include only the flexible region, only the bending region, or both the flexible region and the bending region. The bending region may be a region where a hinge or a gear is arranged and can be bent and deformed, and the flexible region may be a region where a bracelet or a strap can be flexibly deformed.

[0111] By designing the deformable area 22, the device can better fit the human body curve, reduce the pressure and discomfort when worn, and thus improve the wearing comfort of the user. Since the sensor component 1 is thin and self-sealing, the sensor component 1 can be set in the deformable area 22, so that the sensor component 1 can move with the deformable area 22 when the human body moves, and the sensor component 1 fits the human body better, improving the accuracy and reliability of data collection.

[0112] In the related art, the bending area has various motion mechanisms such as hinges, gears, etc., which cannot ensure that the shell is completely sealed in all forms and has no waterproof and dustproof functions. The flexible area includes structures such as watch chains and straps, which cannot ensure that the shell is completely sealed in all forms and has no waterproof and dustproof functions. The health sensors in the related art need to contact the skin, and the related physiological signals are very weak. Components such as chips are also easily affected by moisture and fail, so the requirements for waterproof and dustproof are very high. If the health sensor is added with a waterproof and dustproof structure alone, the thickness will be increased, resulting in the health sensor boss being too high, affecting the consumer's wearing comfort. Therefore, the flexible wearable devices in the related art all fix the health sensor in the straight plate area. In the embodiment of the present application, since the sensor component 1 is thin and self-sealing, the sensor component 1 can be set in the deformable area 22 without being fixed in the straight plate area.

[0113] In some embodiments, see Figure 10-11 The device body 2 is an annular structure and also has a straight plate area 23. The main board of the device body 2 is arranged in the straight plate area 23. The straight plate area 23 and the deformable area 22 are respectively multiple and alternately arranged along the annular direction of the device body 2. One or more deformable areas 22 are provided with a sensor assembly 1. Among them, the straight plate area 23 cannot be bent or deformed and cannot be flexibly deformed.

[0114] The design of the annular structure allows the device to naturally fit the annular parts such as the wrist and ankle, while the alternating arrangement of the straight plate area 23 and the deformable area 22 further improves the device's ability to adapt to complex human body curves. This design not only reduces the sense of oppression when worn, but also improves the stability and comfort of the device.

[0115] The deformable region 22 can bend with the movement of the human body, thereby ensuring that the sensor assembly 1 can still accurately capture data in a dynamic environment. At the same time, the setting of multiple deformable regions 22 can cover a wider range of human body surfaces, improving the comprehensiveness and accuracy of data collection.

[0116] For example, Fig.11 As shown, since the straight plate area 23 and the deformable area 22 are alternately arranged, the main board of the device body 2 is arranged in the straight plate area 23. When the sensor component 1 is arranged in the deformable area 22 adjacent to the straight plate area 23 where the main board of the device body 2 is located, the length of the routing portion 135 can be shortened, which is beneficial to the connection between the flexible circuit board 13 and the main board of the device body 2.

[0117] For example, Fig.11 As shown, as the shape of the wearable device 100 becomes more and more diversified, the wearable device 100 may have multiple straight areas 23 and multiple deformable areas 22. In the future, the wearable device 100 will no longer require a wearing method, and the position close to the skin will become unfixed. Two or more deformable areas 22 can be selected from the many bending areas according to the wearing habits as the setting positions of the sensor component 1. When the wearable device 100 rotates around the wrist, the sensor component 1 can also ensure the reliability and stability of data collection (such as electrocardiogram, blood oxygen, heart rate, etc.).

[0118] In some embodiments, see Figure 1 The device body 2 is an annular structure and also has a straight area 23, and the main board of the device body 2 is arranged in the straight area 23; the deformable area 22 includes a first area 221 and a second area 222, and the straight area 23 is connected to the first area 221 at both ends of the annular direction of the device body 2 through a second area 222 respectively, and the second area 222 is a flexible area, and the routing portion 135 extends to the straight area 23 through the inside of the second area 222.

[0119] According to the wearable device 100 of this embodiment, by setting the main board of the device body 2 in the straight area 23, and using the flexible second area 222 to connect the straight area 23 and the first area 221, the wiring portion 135 extends to the straight area 23 through the inside of the flexible second area 222, thereby avoiding exposure of the wiring on the surface of the device, which not only improves the aesthetics of the device, but also reduces the risk of device failure caused by wiring problems.

[0120] For example, Figure 1As shown, the wearable device 100 is provided with a deformable area 22 such as a strap or a bracelet, and a sensor component 1 is arranged in the front area of ​​the strap close to the wrist. The strap is designed to be hollow, and the wiring portion 135 of the flexible circuit board 13 extends to the straight area 23 of the wearable device 100 through the internal space of the strap and is connected to the main board of the wearable device 100; the strap is soft and elastic, which can make the health sensing structure fit the wrist better, and can also play a role in detecting data (such as electrocardiogram, blood oxygen, heart rate, etc.). This embodiment can save space for the straight area 23 of the wearable device 100, and at the same time provide more possibilities for the morphological design of the wearable device 100.

[0121] Of course, the present application is not limited thereto. For example, in some other embodiments of the present application, see Fig.12 The sensor assembly 1 can also be arranged on the back side of the straight plate area 23 and overlapped with the main board integrated in the straight plate area 23, so that the wiring portion 135 can be further shortened. Thus, the compactness and functional integration of the wearable device 100 can be achieved.

[0122] In summary, the wearable device 100 disclosed in some embodiments of the present invention designs the main board 16 of the sensor component 1 to adopt a flexible circuit board 13 to carry a conductive part 132, a light sensing component 133 and a chip 134, and designs all these electronic components on the front of the flexible circuit board 13, eliminating the space for the connector and the back components, so that the sensor component 1 can be set in the deformable area 22; the mounting portion 111 of the shell 11 is designed with a separation rib 1112 inside to reduce the mutual interference of electronic components, and the connection between the shell 11 and the cover plate 12 adopts a glue encapsulation process to ensure the front sealing; a steel plate is added to the back of the carrier plate portion 131 of the flexible circuit board 13, and the side gaps are filled with UV glue to ensure the back sealing; the flexible circuit board 13 and the cover plate 12 are designed to be oblong to increase the wiring space; the back of the transparent substrate 123 has a light shielding layer 125; the interference of external light on the light sensing component 133 is reduced and the electronic components on the front of the carrier plate portion 131 are shielded.

[0123] Through this design, the health sensor component 1 can be set in the deformable area 22 of the flexible wearable device 100, and it has independent waterproof and dustproof functions regardless of the front or back, and the thickness is reduced; one or more deformable areas 22 such as straps and bracelets can be selected as the setting position of the sensor component 1 according to wearing requirements, so as to meet various wearing methods and save space of the entire device.
