Description

Technical Field

[0001] This invention relates to the field of electronic device technology, and more particularly to a smart host and a smart wearable device. Background Technology

[0002] Smart wearable devices, such as smartwatches and smart bracelets, have become deeply integrated into people's daily lives as rapidly developing electronic products in recent years. Many smart wearable devices are equipped with detection modules. When a user wears the device, the detection module faces the user's body and uses a built-in sensor system to monitor and analyze the user in real time. These sensors can capture physiological parameters such as the user's heart rate, allowing the user to understand their own physical condition.

[0003] The smart wearable device also has a card slot module. When users need to expand the device's functions, they can put the corresponding function card into the card slot module. For example, users can put a SIM card into the card slot module to enable the smart wearable device to make voice calls and other functions.

[0067] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0068] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected" and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0069] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0070] In order to simultaneously house the detection module and the card insertion module within the same intelligent host, the inventors considered adopting... Figure 1 The layout is as follows: A detection module and a card insertion module are arranged one above the other on the main casing of the smart host. The detection module has a sensing area that receives the user's physiological information when the user wears the smart wearable device. The rear card insertion module has a card back cover. When the user needs to install a function card, they use a tool to pry up the card back cover from the right side. During the prying process, the card back cover rotates around its left side, which is the point of contact between it and the main casing.

[0071] However, the inventor discovered Figure 1 The layout of the detection module and card insertion module in the diagram has the following drawbacks. First, point M in the diagram is the center point on the back of the smart host. This layout causes the sensing area to deviate from the center point. When a user wears the smart wearable device, the sensing area may not be in contact with the user's skin, significantly impacting the performance of physiological information detection and hindering accuracy and immediacy. Second, users need to use a special prying tool to pry off the card back cover from one side, and a great deal of force is required, making the card removal and placement cumbersome. Third, when the card back cover is pried off, the stress is concentrated on the card back cover and the main housing at the fulcrum, making them prone to cracking.

[0072] To address the aforementioned issues, this application provides a smart host and a smart wearable device employing the smart host. When worn on a user's body, the smart wearable device can contact or be very close to the user's skin through its sensing area to collect and detect the user's physiological information via a detection module, thereby achieving user health monitoring. The smart wearable device's card slot module can accommodate a SIM card, NFC card, memory card, etc., to expand the device's functionality.

[0073] The smart wearable device can be, but is not limited to, smartwatches, smart bracelets, smart glasses (such as AR glasses, VR glasses, etc.), and smart headphones (such as over-ear headphones, etc.).

[0074] It should be noted that, in order to clearly describe the relative relationships between the components in the smart host of this application, the terms "front" and "back" are used to describe the positional relationship of adjacent components. Specifically, when a user wears the smart wearable device, the back of the smart host is the side facing the user's skin, and the front of the smart host is the side facing away from the user's skin. For ease of understanding, some accompanying drawings use the z-axis to indicate the front-back direction of the smart host, the y-axis to indicate the up-down direction, and the x-axis to indicate the left-right direction.

[0075] Taking the smartwatch's main unit as an example, the smartwatch has a display screen located on the front, while the main casing is located on the back. A raised section protrudes from the main casing in a direction away from the display screen. When the user wears the smartwatch on their left arm, the back of the smartwatch fits snugly against the skin. When the user raises their left wrist to look at the display screen, the left and right sides of the smartwatch correspond to the user's left and right sides of their body. The side of the smartwatch closer to the user's torso is considered the lower side, and the side away from the user's torso is considered the upper side.

[0076] Please refer to the following. Figures 2 to 18 This application describes the smart wearable device.

[0077] A smart wearable device includes a smart host and a wearable component, which is used to wear the smart host onto a user's body. For example, the smart wearable device is a watch, and the wearable component is a watch strap.

[0078] The intelligent host includes a casing 10, a card insertion module 20, and a detection module 30.

[0079] The outer casing 10 protects various devices and structures located within it. The outer casing 10 includes a main casing 11 and a protruding portion 12. The main casing 11 has a base plate and a surrounding frame (omitted in the figure). The base plate and the frame together define a main cavity inside the main casing, which houses the main electronic devices. A display screen (omitted in the figure) is mounted on the front side of the main casing and displays information such as time and health information. Only the base plate of the main casing 11 is shown in the figure. The outer casing 10 also includes a protruding portion 12, which is connected to the main casing 11 and protrudes outward relative to the main casing 11. The protruding portion 12 has a receiving cavity 1201 inside and is provided with a first opening 121 and a second opening 122.

[0080] The card insertion module 20 is disposed in the receiving cavity 1201, and the detection module 30 is at least partially disposed in the receiving cavity 1201. In the front-back direction of the smart host, the card insertion module 20 and the detection module 30 are stacked. The detection module 30 is located behind the card insertion module 20, and the part of the detection module 30 that needs to contact the user's skin is located behind the convex part 12.

[0081] The card insertion module 20 can be, but is not limited to, a SIM card module. The card insertion module 20 includes a card holder 21, which provides a card placement position. This position can be, but is not limited to, a card slot, and the card holder 21 can be used to hold a SIM card. The card holder 21 is slidably connected to the protrusion 12, either directly or indirectly, and can slide relative to the protrusion 12. The card holder 21 can slide outwards from the protrusion 12 via the second opening 122 to a pull-out position, facilitating the insertion of a function card 23 into the card holder 21. The card holder 21 can also slide relative to the protrusion 12 so that the card placement position of the card holder 21 is fully inserted into the receiving cavity 1201, allowing the SIM card and other function cards 23 to be inserted internally and electrically connected to the circuit board.

[0082] The detection module 30 includes a sensor 31 and a cover 32. The sensor 31 is disposed in the receiving cavity 1201 and / or the first opening 121 within the protruding portion 12 to protect the sensor 31. The cover 32 covers the first opening 121 of the protruding portion 12 to seal the receiving cavity 1201, achieving waterproof sealing, etc. The cover 32 has a sensing area 3201 in the middle, meaning that the sensing area 3201 of the cover 32 is not located in the edge area. The sensing area 3201 of the cover 32 is provided with a temperature-conducting component 33 and a transparent window component 322.

[0083] The cover 32 in the detection module 30 can also be called a lens. When the sensor 31 in the convex portion 12 includes a photoelectric sensor 31 (e.g., a PPG sensor 31), a transparent window component 322 is provided on the cover 32 at the position corresponding to the photoelectric sensor 31. The window component 322, in contact with the skin, allows light signals radiated or reflected by the skin to reach the optical receiver 312 inside the receiving cavity 1201 through the window component 322, realizing physiological information detection functions such as heart rate detection and blood oxygen detection. When the sensor 31 in the receiving cavity 1201 includes a temperature sensor 313, a temperature-conducting component 33 is provided on the cover 32 at the position corresponding to the temperature sensor 313. The temperature-conducting component 33, in contact with the skin, can conduct heat to the temperature sensor 313 inside the receiving cavity 1201, realizing body temperature detection.

[0084] The smart host and smart wearable device of this application have a protruding part 12 on the main shell 11. The space of the receiving cavity 1201 of the protruding part 12 can be used to accommodate the card insertion module 20 and the detection module 30, reducing the space occupied inside the main shell 11. When the user wears the smart wearable device, the protruding part 12 contacts the user's skin, avoiding the entire back of the main shell 11 from adhering to the skin surface, reducing stuffiness and improving the wearing experience.

[0085] By stacking the card insertion module 20 in the space in front of the detection module 30, more area can be reserved on the rear surface of the smart host to accommodate the detection module 30. This not only allows the sensing area 3201 of the detection module 30 to be centrally located, but also positions it at the most protruding position on the rear of the smart host. When the user wears the smart wearable device, the centrally located and protruding sensing area 3201 contacts the user's skin. Compared to an off-center sensing area 3201, this design allows for more reliable contact and proximity to the user's skin, thereby improving the accuracy and immediacy of heart rate and body temperature detection. Furthermore, with the sensing area 3201 positioned at the center of the device, arm support is more balanced during wear, resulting in a more comfortable wearing experience.

[0086] This application provides a first opening 121 in the convex portion 12, and the convex portion 12 and the cover 32 are two components, which is more versatile and facilitates the design of different shapes and types of cover 32 according to the needs of detection performance. For example, the number and layout of window components 322 and temperature conducting components 33 on different cover 32 are different, which is more flexible.

[0087] In this application, the card holder 21 is slidably mounted within the protruding portion 12, and a second opening 122 is correspondingly provided on the side of the protruding portion 12. The card holder 21 can be pulled out or pushed in by sliding, thereby enabling the installation and removal of function cards 23 such as SIM cards. Since the card holder 21 is pulled out approximately parallel to the detection module 30, the detection module 30 does not need to be disassembled when installing or removing function cards 23. Furthermore, no special tools are required when sliding the card holder 21, and localized stress concentration is less likely to cause damage to the card holder 21 or the main housing 11. The card holder 21 is located on the side of the protruding portion 12, and its concealed design has minimal impact on the appearance.

[0088] The intelligent host of this application can provide richer health detection functions, more accurate and timely detection results, improve detection performance, take into account appearance and wearing comfort, and also improve the installation and removal experience of function card 23.

[0089] In one embodiment, the protrusion 12 protrudes relative to the main housing 11 toward the rear side of the smart wearable device, that is, the protrusion 12 protrudes relative to the main housing 11 toward the direction away from the display screen, so as to facilitate contact with the user's skin.

[0090] Optionally, the card insertion module 20 is positioned on the front side of the detection module 30, meaning the card insertion module 20 and the detection module 30 are stacked. This allows the entire rear surface of the convex portion 12 to be used for arranging the relevant detection elements of the detection module 30, thus allowing for the placement of more sensors 31 for detecting user health information without increasing the size of the smart host. When a user wears the smart wearable device, the sensing area 3201 of the cover 32 is close to or against the user's skin surface, allowing the sensors 31 to acquire health information such as body temperature and heart rate. It is understandable that many smart wearable devices in related technologies have relatively simple health detection functions. Arranging the detection module 30 and the card insertion module 20 in the same plane parallel to the display screen will cause the sensing area of ​​the detection module 30 to deviate slightly from the center point of the rear side of the smart host, resulting in a certain degree of eccentricity. However, when a user wears a smart wearable device, the center of the rear side of the smart host generally provides the best contact with the skin; therefore, eccentricity of the sensing area of ​​the detection module 30 will reduce detection accuracy. In this embodiment, the detection module 30 is located behind the card insertion module 20. On the one hand, it can center the entire sensing area 3201, improve the fit between the sensing area 3201 and the user's skin, and improve the detection accuracy. On the other hand, more sensors 31 can be arranged in the receiving cavity 1201, and when there are many sensing parts (including temperature-conducting components 33 and window components 322) arranged on the cover 32 for cooperating with the internal sensors 31, the sensing parts can also be centered.

[0091] Alternatively, please continue to refer to Figure 3 The protruding portion 12 has an opening in the main housing 11 on the side opposite to the main housing 11, that is, a first opening 121 is provided on the rear side of the protruding portion 12. A second opening 122 is provided on the side of the protruding portion 12 adjacent to the main housing 11, that is, the second opening 122 is located on the outer peripheral side of the protruding portion 12. For example, in a smart wearable device such as a smartwatch, when the user wears the smart wearable device, the first opening 121 is located on the side of the protruding portion 12 closest to the wrist skin, and the second opening 122 is located on the side of the protruding portion 12 facing the user's body. Both the first opening 121 and the second opening 122 communicate with the receiving cavity 1201 inside the protruding portion 12. In this embodiment, by providing the first opening 121 on the rear side of the protruding portion 12, the cover 32 of the detection module 30 can be arranged on the side of the entire smart host closest to the skin. By setting the second opening 122 on the circumferential side of the protrusion 12, the card support 21 of the card insertion module 20 can be inserted into the receiving cavity 1201 of the protrusion 12 along a direction that is approximately parallel to the display screen and the cover 32. The card support 21 can be inserted into the side of the detection module 30 near the display screen, thereby achieving a stacked layout of the card support 21 and the detection module 30.

[0092] In one embodiment, reference is made to Figures 3 to 7 The side of the cover 32 facing away from the protrusion 12 is the back cover surface. The middle area of ​​the back cover surface is the sensing area 3201 for contact with the user's skin. The back cover surface also includes a transition area 3202, which surrounds the sensing area 3201, or in other words, the sensing area 3201 is located in the middle of the transition area 3202. The transition area 3202 extends from the sensing area 3201 in the middle of the cover 32 to the outer peripheral edge of the cover 32, towards the protrusion 12, that is, the transition area 3202 extends from the middle to the front side of the edge of the smart host. The sensing area 3201 is flat to ensure good contact with the user's skin, and the transition area 3202 is a large arc surface for transition. Compared to the design where the back of the cover 32 is completely flat, this embodiment configures the back of the cover 32 with a small central plane as the sensing area 3201 and a large arc transition around it. This allows the higher central sensing area 3201 to make good contact with the skin when the user wears the smart wearable device, while minimizing contact between the transition area 3202 and the skin. This ensures detection accuracy while reducing the area in contact with the user's skin, avoiding stuffiness, and improving wearing comfort.

[0093] Optionally, the area of ​​the transition zone 3202 occupies more than 40% of the total back cover area to improve wearing comfort. For example, the transition width (dimension in the x-direction) of the transition surface is greater than 4mm for better wearing comfort.

[0094] Optionally, the window component 322 is provided with an optical texture on the side near the receiving cavity 1201. The optical texture can be, but is not limited to, Fresnel texture. The setting of the optical texture facilitates the internal sensor 31 to realize the detection function.

[0095] In one embodiment, the cover 32 includes a main cover portion 321, and a window portion 322 connected to the main cover portion 321. The window portion 322 extends through the main cover portion 321 from front to back, so that both the end of the window portion 322 near the receiving cavity 1201 and the end away from the receiving cavity 1201 are not blocked by the main cover portion 321. This allows the window portion 322 to provide an optical path between the receiving cavity 1201 and the outside of the smart host, wherein light from outside the smart host can enter the receiving cavity 1201 through the window portion. For example, a receiver 312 of the PPG sensor 31 is disposed in the receiving cavity 1201, and the receiver 312 is positioned corresponding to the window portion.

[0096] In configuring the cover 32, to conceal the internal structure and achieve a cleaner, more aesthetically pleasing appearance, the main body 321 of the cover was designed to be opaque. The inventors considered using a glass cover 32, but a glass cover 32 requires a separate opening to assemble the window component 322 with optical textures on the back, making the manufacturing process more complex. Furthermore, a glass cover 32 could pose a safety hazard if cracked by external force, potentially injuring children.

[0097] In this embodiment, the main body 321 and the window component 322 are integrally connected, and the main body 321 and the window component 322 are formed into a plastic structure through a two-color injection molding process. Two-color injection molding technology allows for the creation of composite structures with different materials, colors, and structures by injecting different colored plastic materials in one or two molding processes. This eliminates the need for assembly steps between the main body 321 and the window component 322, and allows for the direct design of optical patterns on the inner side of the window component 322 through injection mold design, eliminating the need for complex processes such as glass cutting, drilling, and assembling Fresnel pattern components. This results in significant cost savings for large-scale production. Furthermore, the plastic cover 32 offers better security. When a curved transition area 3202 needs to be provided on the rear side of the cover 32, it can be more easily achieved through mold design.

[0098] Of course, in other embodiments, the cover body 321 and the window component 322 may also be two separate parts.

[0099] In one embodiment, reference is made to Figure 5 , Figure 6 The cover 32 includes a main body 321 and a plurality of window components 322. The window components 322 in the cover 32 include a first window 3221 and a plurality of second windows 3222, which are arranged around the first window 3221, meaning the first window 3221 is located in the middle of the plurality of second windows 3222. Adjacent second windows 3222 are spaced apart. Optionally, the number of second windows 3222 is three or more.

[0100] Correspondingly, in the sensor 31 disposed within the cavity 1201 of the convex portion 12, reference is made. Figure 13 It includes a light emitter 311 and multiple light receivers 312. The light emitter 311 corresponds to the position of the first window 3221, and the multiple light receivers 312 correspond one-to-one with the positions of multiple second windows 3222. The first window 3221 is used to allow light signals inside the receiving cavity 1201 to be emitted, and the second windows 3222 are used to allow light signals reflected from the user's body to enter the receiving cavity 1201.

[0101] For example, the light transmitter 311 and the light receiver 312 are respectively the transmitter 311 and receiver 312 of the PPG sensor 31, which is used to detect physiological information such as heart rate and blood oxygen saturation. The first window 3221 is the transmission window, and the second window 3222 is the reception window. By centering the transmission window of the PPG and setting the reception windows in multiple directions, such as four directions, measurement errors caused by wearing misalignment are prevented, resulting in high reliability.

[0102] In this embodiment, multiple second windows 3222 are provided within the sensing area 3201 of the cover 32, and correspondingly, multiple light receivers 312 are provided within the receiving cavity 1201. This allows multiple light receivers 312 to receive reflected light from different positions. Thus, even when the user wears the smart wearable device, and even if the sensing area 3201 is only partially in contact with the skin, at least one second window 3222 can be in contact with the skin, and at least one light receiver 312 can receive sufficiently strong light, thereby reducing measurement errors caused by misalignment. The multiple second windows 3222 enable data collection from multiple locations, and multiple data points further improve the accuracy and reliability of physiological parameter measurements.

[0103] Furthermore, surrounding a single light transmitter 311 with multiple light receivers 312 can, on the one hand, make more effective use of the width space inside the device, which is beneficial to reducing the area occupied by the sensing area 3201 and is conducive to central placement; on the other hand, the surrounding arrangement of multiple light receivers 312 can reduce the impact of external light interference.

[0104] In one embodiment, reference is made to Figure 3 , Figure 11 The main body 321 of the cover has a through hole 3211. The detection module 30 includes a temperature-conducting component 33, which is disposed within the through hole 3211. A contact-type temperature sensor 313 is disposed within the receiving cavity 1201. The temperature sensor 313 is positioned corresponding to the temperature-conducting component 33. The front side of the temperature-conducting component 33 is in thermal contact with the temperature sensor 313, while the rear side of the temperature-conducting component 33 is exposed for contact with the skin. The temperature-conducting component 33 is used to conduct the user's skin temperature to the temperature sensor 313. The material of the temperature-conducting component 33 can be, but is not limited to, steel, copper, etc.

[0105] The detection module 30 includes a temperature sensor 313, a temperature-conducting component 33, a transmitter 311 of a PPG sensor 31, a first window 3221, receivers 312 of multiple PPG sensors 31, and multiple second windows 3222. It can simultaneously perform multiple physiological information detection functions such as temperature detection and heart rate detection. By collaboratively processing multiple physiological information, it can obtain richer health monitoring, sleep monitoring, and exercise monitoring functions. However, it is understandable that when multiple sensors 31 are integrated into the detection module 30, how to arrange the internal sensors 31 and how to position the cover 32 becomes a challenge. To solve this layout problem of the detection module 30, the detection module 30 can be configured as follows:

[0106] like Figure 5 , Figure 6 The detection module 30 cleverly utilizes multiple second windows 3222 arranged along a circular or elliptical trajectory to also place the temperature-conducting component 33 on this circular or elliptical trajectory. The temperature-conducting component 33 is positioned between adjacent second windows 3222, so that the temperature-conducting component 33 is as close to the center as possible without affecting the size of the entire sensing area 3201. The closer the temperature-conducting component 33 is to the center, the better it can fit with the user's skin, thereby transferring the user's body surface temperature to the internal temperature sensor 313 and improving the accuracy of temperature measurement.

[0107] Understandably, while the arrangement of "first window 3221 located in the center, multiple second windows 3222 surrounding the first window 3221, and temperature-conducting component 33 located between the first window 3221 and the second windows 3222" allows the temperature-conducting component 33 to be closer to the central area for more accurate temperature measurement data, the presence of the temperature-conducting component 33 increases the distance between the second windows 3222 and the first window 3221, potentially affecting the immediacy and accuracy of the light signal received by the second windows 3222 and the light receiver 312. This embodiment, by arranging the second windows 3222 and the temperature-conducting component 33 on the same circular or elliptical trajectory, ensures that both the second windows 3222 and the temperature-conducting component 33 are closer to the first window 3221. Furthermore, the circular or elliptical trajectory layout makes the overall appearance of the sensing area 3201 neater and more aesthetically pleasing, improving its overall integrity and ensuring measurement accuracy while minimizing the area occupied by the sensing area 3201.

[0108] In one embodiment, reference is made to Figures 2 to 7The cover 32 has a rectangular structure. It should be noted that cover 32 structures where the long and short sides are connected by curved bevels also fall under the category of rectangular structures. The dimension of the cover 32 in the left-right direction of the smart device is d1, and the dimension in the top-bottom direction is d2, where d1 is smaller than d2. This means the cover 32 is smaller in the left-right direction and larger in the top-bottom direction. By adopting a rectangular design, both wearing comfort and measurement stability can be considered: the smaller left-right dimension of the cover 32 reduces the risk of light leakage. The larger top-bottom dimension of the cover 32 increases the support strength between the arm and the cover 32 in the top-bottom direction when the smart wearable device is worn on the arm or wrist, improving wearing stability and preventing issues such as the smartwatch being misaligned, tilted, or causing light leakage.

[0109] Understandably, light leakage refers to the situation where, when a smartwatch is worn on the forearm or wrist, the left or right side of the smartwatch is tilted up, or the smartwatch is not worn correctly, resulting in an excessively large gap between the rear sensing area 3201 and the user's skin. This allows too much external ambient light to enter this gap, causing some of the light entering the receiving cavity 1201 through the second window 3222 to be ambient light rather than light reflected from the arm, thus affecting detection accuracy. In this embodiment, by using a rectangular cover 32 with the sensing area 3201 positioned centrally on the rear side of the cover 32, and with the sensing area 3201 being the highest plane on the rear side of the cover 32, both detection accuracy and support during wear are balanced.

[0110] Compared to a circular cover 32, a rectangular cover 32 can have a larger length under the same watch width conditions. This increases the vertical dimension of the rectangular cover 32 when worn by the user. Even if the smartwatch tends to tilt up at the top or bottom, the curved surface of the upper or lower side of the sensing area 3201 of the rectangular cover 32 can support the arm and prevent the tilt angle from being too large. It also helps to prevent light leakage.

[0111] In one embodiment, the cover 32 includes a first window portion 3221 and four second window portions 3222, and the cover 32 is also provided with two temperature-conducting components 33. Two of the second window portions 3222 are arranged along a first horizontal direction on opposite sides of the first window portion 3221, and the other two second window portions 3222 are arranged along a second horizontal direction on opposite sides of the first window portion 3221. The two temperature-conducting components 33 are arranged along a third horizontal direction on opposite sides of the first window portion 3221. Figure 6The three dashed lines in the middle represent three reference lines extending in the first horizontal direction, the second horizontal direction, and the third horizontal direction. Each temperature-conducting component 33 is located between two adjacent second window portions 3222, and the temperature-conducting component 33 is spaced apart from the adjacent second window portions 3222. In this embodiment, the arrangement of two temperature-conducting components 33 can provide two temperature measurement points, improving temperature measurement redundancy and accuracy, ensuring that at least one temperature-conducting component 33 is in contact with the skin. When both temperature-conducting components 33 are in contact with the skin, the body temperature can be determined more accurately through the detection results of the two temperature sensors 313.

[0112] Optionally, the horizontal centerline extends along the left-right direction (x-direction) of the smart wearable device, and the vertical centerline extends along the up-down direction (y-direction) of the smart wearable device. The intersection of the horizontal and vertical centerlines is located at the center of the first window portion 3221. The four second windows 3222 include four second windows 3222 located at the top left, bottom left, top right, and bottom right. Specifically, the top left and bottom left second windows 3222 are located on either side of the horizontal centerline, the top right and bottom right second windows 3222 are located on either side of the vertical centerline, the top left and top right second windows 3222 are located on either side of the vertical centerline, and the bottom left and bottom right second windows 3222 are located on either side of the vertical centerline. These four second windows 3222 are arranged at an angle. Thus, when the smart wearable device is a smartwatch, even if the left side of the smartwatch is slightly tilted up when worn on the arm, the upper right and lower right second windows 3222 can still fit well against the skin to reduce light leakage. Similarly, even if the top of the smartwatch is slightly tilted up, the lower left and lower right second windows 3222 can still fit well against the skin to reduce light leakage. In this way, under various tilting conditions, at least two second windows 3222 can fit well against the skin to reduce light interference caused by light leakage. The ingenious layout of these four second windows 3222 ensures good measurement accuracy under various wearing conditions.

[0113] It is understandable that arranging the four second windows 3222 at approximately a 45-degree angle in the four directions of the first window 3221 (upper left, lower left, upper right, and lower right) can more effectively utilize the space in the width direction of the cover 32 and minimize the size of the cover 32 in the width direction.

[0114] Optionally, the two temperature-conducting components 33 are located on both sides of the longitudinal centerline, that is, on the upper and lower sides of the first window portion 3221. It can be understood that when the cover 32 is rectangular, since the lateral dimensions of the cover 32 are minimized, arranging the two temperature-conducting components 33 one above the other utilizes the space of the cover 32 and keeps the temperature-conducting components 33 as close to the center as possible, thereby improving the reliability of the contact between the temperature-conducting components 33 and the skin.

[0115] In one embodiment, reference is made to Figure 2 , Figure 5 , Figure 7 The surface of the first window portion 3221 facing away from the receiving cavity 1201 is circular or square, which helps to reduce light leakage when wearing. The surface of the second window portion 3222 facing away from the receiving cavity 1201 is fan-shaped, and the surface of the temperature-conducting component 33 facing away from the receiving cavity 1201 is also fan-shaped. This allows multiple second window portions 3222 and two temperature-conducting components 33 to be arranged along the same circular or elliptical trajectory, while also maintaining an aesthetically pleasing appearance.

[0116] The thermal conductivity of the cover 32 is generally poor. If the thermally conductive component 33, the cover body 321, and the window component 322 are directly integrally molded, the thermal conductivity requirements cannot be met. In one embodiment, the thermally conductive component 33 is assembled to the cover 32. (Refer to...) Figure 2 , Figure 3 The cover 32 includes a main body 321 and a window portion, which are integrally connected to the main body 321. Correspondingly, the main body 321 is provided with a through hole 3211, and the temperature-conducting component 33 can be assembled into the through hole 3211. In order to achieve waterproof protection for the devices inside the cavity 1201, a waterproof material needs to be provided between the temperature-conducting component 33 and the main body 321.

[0117] The inventors considered attaching a full ring of waterproof double-sided tape to the front of the temperature-conducting component 33, but found that the waterproof double-sided tape had a large adhesion area and its design was not flexible enough to meet the waterproof requirements of the overall miniaturized design. For example, when the cap 331 of the temperature-conducting component 33 is designed as an irregular shape (e.g., a fan-shaped ring) according to appearance requirements, the waterproof double-sided tape needs to be cut into the same irregular shape, which is quite troublesome.

[0118] This embodiment uses a sealing ring fitted around the outer periphery of the temperature-conducting component 33 for waterproofing, eliminating the need to apply sealant to the front side of the temperature-conducting component 33. This makes assembly simple, provides good stability, and allows for flexible and adaptable design schemes, making it suitable for temperature-conducting components 33 of different shapes.

[0119] Optionally, refer to Figure 3 The main body 321 of the cover is provided with a cover through hole 3211 and a limiting groove 3212. The limiting groove 3212 is located on the side of the cover through hole 3211 away from the receiving cavity 1201. The limiting groove 3212 is connected to the receiving cavity 1201 through the cover through hole 3211. Figure 10 The diagram illustrates the structure of the temperature-conducting component 33 at different angles. The temperature-conducting component 33 includes a pillar 332 and a cap 331 connected to one end of the pillar 332 and protruding relative to the outer wall of the pillar 332. The end of the cap 331 facing away from the pillar 332 is exposed for contact with the user's skin. (See reference...) Figure 10The cap 331 is fitted into the limiting groove 3212, and the column 332 passes through the cover through hole 3211. A first sealing ring 34 is fitted around the outside of the column 332. The first sealing ring 34 abuts against the wall of the cover through hole 3211. Waterproof sealing protection is achieved through the first sealing ring 34 between the temperature-conducting component 33 and the wall of the cover through hole 3211. During assembly, the first sealing ring 34 can be fitted over the temperature-conducting component 33 first, and then the temperature-conducting component 33 can be inserted into the cover through hole 3211. During the insertion of the temperature-conducting component 33, when the groove surface of the limiting groove 3212 abuts against the front side of the cap 331, it restricts the temperature-conducting component 33 from being inserted further inward, and the temperature-conducting component 33 is inserted into place.

[0120] Understandably, the cap 331 can be designed in different shapes as needed, while the column 332 can be designed as a cylinder, which makes it convenient to use a circular sealing ring to fit around the column 332 for waterproofing, thus balancing the flexibility of the cap 331 shape design with the ease of installation of the first sealing ring 34.

[0121] Alternatively, please continue to refer to Figure 11 The temperature-conducting component 33 includes a fastening portion 333, which is connected to the end of the post portion 332 opposite to the cap portion 331. A limiting portion is provided on the wall of the cover through-hole 3211, and the fastening portion 333 engages with the limiting portion to restrict the temperature-conducting component 33 from moving away from the receiving cavity 1201 and detaching from the cover body 32. The design of the fastening portion 333 facilitates the secure fastening of the temperature-conducting component 33 onto the cover body 321, making it less prone to loosening after insertion. In this embodiment, the design of the cap portion 331, post portion 332, and fastening portion 333 of the temperature-conducting component 33 simplifies and facilitates the implementation of a waterproofing solution between the temperature-conducting component 33 and the cover body 321. Furthermore, the temperature-conducting component 33 only needs to be inserted in a straight line to achieve fastening with the cover body 321, making assembly convenient, quick, reliable, and cost-effective.

[0122] In one embodiment, please refer to Figure 13 The smart host includes a motor module 50, which is used for vibration to provide haptic feedback. When the card insertion module 20 is a SIM card module, the smart host has the function of receiving incoming calls and messages. The motor module 50 can provide notifications for incoming calls via vibration, and can also provide reminders for health information such as abnormal heart rate or steps reaching a target. When arranging the motor module 50, the inventors considered placing it within the main cavity of the main housing. However, they found that the motor module 50 is relatively large. Placing a large battery and motor module 50 within the main cavity would result in a large overall size of the host, which is not conducive to miniaturization design.

[0123] In this embodiment, the motor module 50 is arranged within the receiving cavity 1201. The receiving cavity 1201 formed inside the protruding part 12 can accommodate the motor module 50, reducing the thickness of the host and facilitating overall miniaturization. In the z-axis direction of the smart host, the motor module 50 and the card insertion module 20 are located on the same side of the detection module 30, that is, both the motor module 50 and the card insertion module 20 are located in front of the detection module 30. The arrangement of the motor module 50 does not occupy the rear space and does not affect the rear layout of the detection module 30.

[0124] Optionally, with both the convex portion 12 and the cover 32 being rectangular, and the vertical (y-axis) dimensions of the convex portion 12 and the cover 32 being larger than their horizontal (x-axis) dimensions, the larger vertical dimension of the cover 32 effectively supports the smart device when worn, preventing it from tilting and ensuring the sensing area 3201 fits snugly against the skin. Furthermore, the y-axis dimension of the convex portion 12 allows for the adjacent placement of the motor module 50 and the card insertion module, resulting in a more rational internal space layout. Moreover, when the motor module 50 is positioned within the cavity 1201 of the convex portion 12, it is closer to the user's skin when wearing the smart wearable device, resulting in stronger and more immediate vibration feedback and a better user experience.

[0125] In one embodiment, reference is made to Figure 9 , Figure 14 , Figure 15 Since the card support 21 in the card insertion module 20 is directly or indirectly slidably installed on the protrusion 12, in order to achieve waterproofing at the second opening 122 of the protrusion 12, the card support 21 is fitted with a second sealing ring 24.

[0126] Optionally, the card holder 21 includes a card holder body 211, a card holder neck 212, and a card holder outer end 213. The card holder body 211 is connected to the card holder outer end 213 via the card holder neck 212. The card holder 21 is provided with a card slot for holding a SIM card or other functional card 23. A second sealing ring 24 is fitted onto the card holder neck 212. The card holder outer end 213 provides a position for the user to apply external force, facilitating pushing the card holder 21 inward or pulling it outward.

[0127] Card holder 21 has an insertion position and a withdrawal position. For example... Figure 9 As shown, when the card support 21 is in the insertion position, the card holder body 211 is located in the receiving cavity 1201 of the protrusion 12, the card holder neck 212 is located at the second opening 122, and the second sealing ring 24 abuts against the edge wall of the second opening 122, so as to achieve waterproofing at the second opening 122 when the card support 21 is inserted into place.

[0128] In this configuration, the card holder 21 and the detection module 30 are stacked in the z-axis direction of the smart host; in the y-axis direction of the smart host, the motor module 50 and the second sealing ring 24 are located on opposite sides of the card holder body 211. For example, the convex portion 12 is rectangular in shape with its vertical dimensions larger than its horizontal dimensions. By placing the space-consuming second sealing ring 24 and motor module 50 on the vertical sides of the card holder body 211, the internal space can be fully utilized. This allows the motor module 50 and the card holder body 211 to be roughly arranged in the same plane, reserving more thickness space for the SIM card to be placed in the card slot of the card holder body 211.

[0129] Optionally, the intelligent host also includes a device group 60, which consists of peripheral devices for cooperating with the detection module 30. Correspondingly, in the y-axis direction of the intelligent host, the device group 60 and the motor module 50 are located on the side of the card holder body 211 opposite to the second sealing ring 24; in the x-axis direction of the intelligent host, the device group 60 and the motor module 50 are adjacent. For example, the second sealing ring 24, which occupies a relatively large space, is located at the 6 o'clock position, the motor module 50, which also occupies a relatively large space, is located at the 1 o'clock position, and the device group 60 is located at the 11 o'clock position. This layout has high space utilization.

[0130] Optionally, to facilitate the user's manual removal of the card holder 21 to insert the function card 23 into the card slot, a notch is provided on the card holder 21, allowing the user to pull the card holder 21 outwards using their fingertip or a toothpick. When the card holder 21 is in the inserted position, the outer end of the card holder is located outside the protrusion 12, as shown in the reference section. Figure 9 , Figure 14 , Figure 15 The outer end 213 of the card tray is provided with a first notch 214, and correspondingly, a second notch 323 is also provided on the side of the cover 32 near the outer end 213 of the card tray, such as... Figure 1 , Figure 16 The diagram illustrates that the first notch 214 and the second notch 323 together define the disassembly notch. When disassembling, the user can insert their fingers or other tools through the disassembly notch into the first notch 214 of the outer end 213 of the card tray, thereby pulling the card support 21 outwards to expose the card slot. With the second notch 323 provided in the cover 32, the first notch 214 of the outer end 213 of the card tray does not need to be very deep, which helps to reduce the thickness of the card support 21.

[0131] If a groove is provided only at the end of the card support 21 to provide a disassembly notch, the outer end of the card support 21 needs to protrude outwards at a certain position relative to the edge of the cover 32, and a groove is provided on the side of the outer end of the card support 21 away from the main housing 11. In this way, the groove of the first opening 121 of the card support 21 can be easily seen from the back of the smart host. Not only is the appearance unsightly, but this position is also prone to the accumulation of sweat and other substances, which is not conducive to waterproof protection.

[0132] In this embodiment, refer to Figure 9 The disassembly notch is formed by the arc-shaped notch (second notch groove 323) of the cover 32. When the outer shell 10 is in the upright state, the user can directly remove the card support 21 from the back of the smart host. When the outer shell 10 is in the normal state, it does not affect the contact experience of wearing the arm and avoids the relatively poor user experience of taking the card from the side.

[0133] The cover 32 partially covers the rear side of the outer end 213 of the card tray, and the second notch 323 of the cover 32 is opened on the front side and is inclined into the receiving cavity 1201. In this way, the cover 32 not only covers the first notch 214 of the outer end 213 of the card tray from the rear, but also has an aesthetic appearance that helps prevent sweat from entering and hides the disassembly notch.

[0134] Optionally, the smart host includes a tray bracket 70, which is rotatably connected to the housing 10 so that the housing 10 can be in a normal state (e.g., Figures 7 to 9 (Illustrative) and standing state (e.g.) Figure 16 (Illustrative) Switching between. The tray bracket 70 has a clearance hole. When the outer shell 10 is in the normal state, the main shell 11 abuts against the tray bracket 70, the protrusion 12 passes through the clearance hole, and the tray bracket 70 covers the periphery of the first notch 214. When the outer shell 10 is in the upright state, the main shell 11 is tilted or vertical relative to the tray bracket 70. For example, the smart wearable device is a watch. The two ends of the tray bracket 70 are connected to the watch strap. When the user wears the smart watch normally, the outer shell 10 of the smart host is in the normal state, the smart host is flat, and the tray bracket 70 is located on the side of the smart host closer to the arm. The protrusion 12 passes through the tray bracket 70 and contacts the skin, without affecting body temperature and heart rate detection. When the user needs to raise their wrist and stand the watch body upright to take a picture or video, the outer shell 10 can be flipped up relative to the tray bracket 70. It can be understood that, as Figure 8 , Figure 9As shown, when the outer casing 10 is in its normal state, the tray bracket 70 at least covers one side of the outer end 213 of the card tray. This, combined with the cover 32 covering the rear side of the outer end 213 of the card tray, allows for the concealment of the card support 21 and its first notch 214. This results in an aesthetically pleasing appearance and prevents sweat from entering. It is understandable that children, when wearing a smartwatch, are prone to accidentally touching various parts. In this embodiment, when the outer casing 10 is laid flat in its normal state, the tray bracket 70 covers the outside of the first notch 214, preventing the user from accidentally removing the card support 21. Figure 16 To illustrate, when the card support 21 needs to be pulled out and the function card 23 needs to be disassembled or assembled, the main housing 11 is flipped up relative to the tray bracket 70 to expose the first notch 214 at the disassembly notch.

[0135] Compared to Figure 1 The previous solution involved opening the card cover by prying it open with a special tool using a force of nearly 1 kg. This new solution allows the card holder 21 to be pulled out directly with a fingernail, requiring less than 300g of force, and the card holder 21 is less likely to accidentally detach. The card holder 21 is also secured internally by a spring-loaded mechanism, preventing complete accidental detachment.

[0136] In one embodiment, the smart host includes a flexible circuit board 40, and the electronic components in the card insertion module 20 and detection module 30 are mounted on the same flexible circuit board 40 to improve overall compactness. (See also...) Figure 17 The flexible circuit board 40 is bent in the middle to form a first circuit layer 41 and a second circuit layer 42 spaced apart along the z-axis. The first circuit layer 41 is located at the rear, and the second circuit layer 42 is located at the front. The first detection module 30, the first circuit layer 41, the card insertion module 20, and the second circuit layer 42 are arranged from back to front along the z-axis of the smart host. The sensor 31 in the detection module 30 is installed in the first circuit layer 41. The card support 21 has a card slot on the side near the second circuit layer. When a function card 23 is installed in the card slot, the function card 23 can be electrically connected to the second circuit layer 42.

[0137] Optionally, the card insertion module 20 includes a card holder 22, which defines a card insertion space between the card holder 22 and the second circuit layer 42. The card support member 21 is at least partially located within the card insertion space and is slidably mounted on the card holder 22. (Two modules are powered through the same FPC, resulting in a smaller footprint.)

[0138] In this embodiment, the electronic components in the card insertion module 20 and the electronic components in the detection module 30 can be inserted into the main control circuit board inside the main cavity via the same connector of the flexible circuit board 40, thereby realizing the electrical connection between the detection module 30, the card insertion module 20, and the main control circuit board. Compared to setting two independent PCBs for the card insertion module 20 and the detection module 30, and connecting the two PCBs to the main control circuit board through wires, the flexible circuit board 40 in this embodiment not only simplifies the wiring connecting the two modules to the main control circuit board and simplifies the assembly steps, but also occupies less thickness space within the narrow space of the cavity 1201 of the protrusion 12. Furthermore, the flexible circuit board 40 is flexible, making it less prone to damage when bent during electrical connections, whereas the single-solder connection method for wires is prone to loosening at the solder joints.

[0139] Optionally, a first steel plate can be provided on the side of the first circuit layer 41 near the second circuit layer, and a second steel plate can be provided on the side of the second circuit layer 42 away from the first circuit layer 41, to reinforce the flexible circuit board 40. The steel plate is connected and fixed to the flexible circuit board 40 by adhesive bonding, and a relatively thin steel plate can be used.

[0140] In one embodiment, reference is made to Figure 17 , Figure 18 The first circuit layer 41 is provided with a first positioning hole 411, and the cover 32 is provided with a first positioning post 324, which passes through the first positioning hole 411. (Refer to...) Figure 17 , Figure 19 The second circuit layer 42 is provided with a second positioning hole 421, and the convex part 12 is provided with a second positioning post 123, which passes through the second positioning hole 421.

[0141] Optionally, the smart host includes a support plate 81, which is disposed on the side of the second circuit layer 42 opposite to the card insertion module 20. The second circuit layer 42 is bonded to the support plate 81, and the support plate 81 is connected to the protrusion 12 or the main housing 11 by fasteners 82.

[0142] Reference Figure 19 The support plate 81 is provided with a third positioning hole (not marked in the figure), and the second positioning post 123 passes through both the second positioning hole 421 of the second circuit layer 42 and the third positioning hole of the support plate 81.

[0143] During assembly, sensor 31 is welded to the first circuit layer 41, card holder 22 from card module 20 is placed on the second circuit layer 42, and support plate 81 is placed on the side of the second circuit layer 42 opposite to the first circuit layer 41. An adhesive layer is placed between support plate 81 and the second circuit layer 42. The adhesive layer includes a low-compression material substrate and double-sided adhesive on both sides. The positioning post of the fixture passes through the second positioning post 123 and the third positioning post simultaneously to first achieve the positioning of support plate 81 and the second circuit layer in the x and y directions. Then, support plate 81 and the second circuit layer are glued and fixed together by the adhesive layer. Then, the first positioning hole 411 of the first circuit layer 41 passes through the first positioning post 324, and the second positioning hole 421 of the second circuit layer 42 and the third positioning hole of support plate 81 pass through the third positioning post. Then, multiple fasteners 82 are used in multiple positions to lock and fix support plate 81 to the protrusion 12 or the main housing 11.

[0144] The adhesive layer substrate can be a low-compressibility material such as PET, PI, or fiberglass board, occupying less thickness space. This assembly method ensures the consistency and accuracy of the positions of the sensor 31 and the card holder 22 in the z-axis, x-axis, and y-axis directions, allowing the PPG sensor 31 to accurately align with the window component 322, the temperature sensor 313 to accurately align with the temperature-conducting component 33, and the card support 21 to accurately insert between the card holder 22 and the second circuit layer 42, thereby providing accurate, stable, and reliable detection and card insertion / removal functions.
