Description

[0001] This application is a divisional application. The original application has the application number 202110560247.9 and the original application date is May 21, 2021. The entire contents of the original application are incorporated herein by reference. Technical Field

[0002] This application relates to the field of electronic device technology, and more particularly to a wearable device. Background Technology

[0003] With the rapid development of wearable devices, people have increasingly higher demands for their functions. Among these, body temperature measurement is a very practical function.

[0004] Current wearable devices with body temperature measurement capabilities typically employ contact-based measurement modules. These modules measure temperature by attaching a temperature sensor to the device's housing. However, contact-based modules are susceptible to variations in the housing's thermal conductivity and ambient temperature, leading to potentially large measurement errors. Summary of the Invention

[0005] This application provides a wearable device that can measure human body temperature, and the measurement accuracy is effectively improved.

[0006] This application provides a wearable device, which may include a shell, a thermally conductive structure, an ambient temperature measurement module, and a skin-touch temperature measurement module. The shell includes a first housing and a second housing, which are interlocked to form a receiving space within the shell. The first housing includes a first surface, and the second housing includes a second surface; the first and second surfaces are connected by a connecting wall. The thermally conductive structure includes a first thermally conductive end and a second thermally conductive end. The first thermally conductive end is used to collect ambient temperature, and the second thermally conductive end is located within the receiving space. The ambient temperature measurement module is disposed on the second thermally conductive end, and the ambient temperature collected by the first thermally conductive end can be transmitted to the ambient temperature measurement module via the second thermally conductive end to obtain ambient temperature data. The skin-touch temperature measurement module is located within the receiving space of the shell and is disposed on the first surface of the first housing, for collecting skin temperature. Using the solution provided in this application, the heat-conducting structure conducts the ambient temperature collected by the first heat-conducting end to the second heat-conducting end located in the containment space, and then conducts it to the ambient temperature measurement module, forming a stable ambient temperature conduction path within the housing, so as to have less impact on the overall appearance of the device; the ambient temperature data measured by the ambient temperature measurement module and the skin temperature data measured by the skin-touch temperature measurement module are used as input quantities, and human body temperature data are obtained through an algorithm, which can effectively improve the accuracy of human body temperature measurement.

[0007] Wearable devices typically have buttons, which can be located on the connecting wall of the housing. In one possible implementation of this application, the heat-conducting structure can be a button, which typically includes a button cap and a button lever. The button cap can be located on the connecting wall to serve as a first heat-conducting end for collecting ambient temperature. The button lever is fixedly connected to the button cap and is located within the receiving space. The end of the button lever facing away from the button cap serves as a second heat-conducting end for housing the ambient temperature measurement module. In this application, collecting ambient temperature via a button effectively simplifies the structure of the wearable device; placing the ambient temperature measurement module inside the housing protects it from the housing's confinement.

[0008] When designing buttons, they can be configured as a single-piece molding structure. The molding method can be, but is not limited to, multi-shot injection molding, multi-shot casting, three-dimensional additive manufacturing, or powder metallurgy, to improve the structural stability of the buttons. Alternatively, buttons can be configured as an assembly structure, in which case the button cap and button rod can be fixedly connected by, but is not limited to, welding, bonding, riveting, snap-fitting, or threaded connections.

[0009] In one possible embodiment of this application, the keycap and / or key lever may be configured as an inner and outer layer structure. This inner and outer layer structure may include an inner layer portion and an outer layer portion, wherein at least one surface of the inner layer portion may contact the outer layer portion. The thermal conductivity of the material of the outer layer portion may be 35-200 W / (m·K), thus enabling the outer layer portion to have high thermal conductivity while also possessing relatively reliable structural stability, thereby meeting the structural strength requirements of the entire key. Furthermore, the surface of the outer layer portion may have surface treatment features including, but not limited to, polishing, painting, brushing, or matte finishes, to improve the aesthetic appearance of the key. The thermal conductivity of the material of the inner layer portion may be 200-380 W / (m·K), which is beneficial for improving the overall thermal conductivity efficiency of the key.

[0010] In one possible implementation of this application, the button lever may be provided with a waterproof groove, and a first sealing element is installed in the waterproof groove. The first sealing element is interference-fitted with the button lever and the housing, thereby playing a waterproof sealing role.

[0011] In one possible implementation of this application, at least a portion of the keycap can extend from the connecting wall to the outside of the housing, which can effectively increase the contact area between the keycap and the external environment, thereby improving the accuracy of the keycap in collecting ambient temperature.

[0012] Additionally, at least a portion of the button cap extends outside the housing, allowing control of the corresponding function by pressing or rotating the button. When the button is a push-button button, it may also include a spring element, which may be located on the side of the button cap facing the button lever. Furthermore, the spring element may elastically abut against the housing or a structural member disposed within the receiving space.

[0013] In one possible implementation of this application, the ambient temperature measurement module may include a first temperature sensor and a first circuit board assembly. The first circuit board assembly may include a first circuit board, and the first temperature sensor may be disposed on the first circuit board and electrically connected to the first circuit board. The ambient temperature measurement module can receive the ambient temperature through the first temperature sensor and / or the first circuit board. In a specific implementation, one of the first temperature sensor and the first circuit board may be fixed to a second heat-conducting end. In this way, the ambient temperature collected by the first heat-conducting end is conducted to the second heat-conducting end and then received by the ambient temperature measurement module. The heat conduction path is shorter, which is beneficial for improving the measurement accuracy of the ambient temperature.

[0014] To improve the reliability of the connection between the ambient temperature measurement module and the button, in one possible implementation of this application, the ambient temperature measurement module may further include a cover plate. This cover plate is fitted onto the assembly structure formed by the connection between the first temperature sensor, the first circuit board, and the end of the button lever opposite to the button cap. Furthermore, the cover plate may have an inner contour that matches the outer contour of the aforementioned assembly structure, thereby providing better fixation and protection capabilities, and reducing the space occupied by the cover plate within the housing of the wearable device.

[0015] In this application, besides using buttons as heat-conducting components, in another possible implementation, the heat-conducting structure can also be configured as an independent structure. In a specific configuration, this heat-conducting structure may further include a connecting portion for connecting the first heat-conducting end and the second heat-conducting end. It is understood that this heat-conducting structure can be a one-piece molded structure to improve its structural stability.

[0016] The connecting wall of the outer casing can also be provided with a button slot for mounting buttons, and the first heat-conducting end of the heat-conducting structure can extend into the button slot to collect ambient temperature. In addition, there is a clearance space between the button and the first heat-conducting end to avoid interference when they perform their respective functions.

[0017] In one possible implementation of this application, a support can be provided on the side of the connecting wall of the shell located within the accommodating space. This support can provide support for the connecting wall, thereby improving the structural stability of the entire shell.

[0018] The connecting part of the heat-conducting structure can be embedded in a bracket, which reduces the space occupied by the heat-conducting structure. In addition, by embedding the heat-conducting structure in the bracket, the bracket can also support the heat-conducting structure, which reduces the need to consider the structural strength of the heat-conducting structure. This allows the heat-conducting structure to be made of a material with a high thermal conductivity, thereby improving the accuracy of its temperature detection.

[0019] In another possible implementation of this application, the connecting wall can also be used as a heat-conducting structure. The side of the connecting wall outside the receiving space can serve as the first heat-conducting end, and the side of the connecting wall inside the receiving space can serve as the second heat-conducting end. This effectively simplifies the structure of the wearable device and facilitates the acquisition of ambient temperature.

[0020] In one possible embodiment of this application, foam may be attached to the side of the ambient temperature measurement module away from the second heat-conducting end to protect the ambient temperature measurement module.

[0021] In a specific configuration, this skin-touch temperature measurement module may include a second temperature sensor and a second circuit board assembly. The second circuit board assembly includes a second circuit board, on which the second temperature sensor may be disposed, and the two are electrically connected.

[0022] The wearable device may also include a photoplethysmography (PPG) lens disposed thereon. Additionally, the PPG lens may be part of the first surface of the wearable device's housing. This allows a second temperature sensor and one of a second circuit board to be fixed to the PPG lens for acquiring human skin temperature.

[0023] In one possible implementation of this application, the thermal conductivity of the photoplethysmography lens can be 35-55 W / (m·K), which is relatively high and thus helps to improve the accuracy of the skin temperature collected by the skin-touch temperature measurement module.

[0024] The lens of a photoplethysmography (PPG) scanner can be divided into a transparent area and a non-transparent area. This allows light emitted from the PPG module's light source to pass through the transparent area and enter the human body, or allows light reflected from the human body to pass through the transparent area and be received by the PPG module's photodetector. Furthermore, by adjusting the position of the light source or the direction of light emission, as much light as possible can pass through the transparent area, thereby reducing energy loss and improving the detection accuracy of the PPG module.

[0025] Skin-touch temperature sensors can have a non-transparent area set in the lens of a photoplethysmometer to prevent it from blocking light emitted or reflected from the light source.

[0026] In one possible implementation of this application, the skin-contact temperature measurement module may further include a temperature measuring structure. This structure includes a heat-conducting element, which comprises a fixed portion and a contact portion connected together. The fixed portion is located within the receiving space and is fixedly connected to the outer casing, thereby achieving a fixed connection between the heat-conducting element and the outer casing. Additionally, one of the second temperature sensor and the second circuit board is fixed to the side of the fixed portion opposite to the contact portion. The first housing has a mounting hole that penetrates through the first surface, and at least a portion of the contact portion extends out of the mounting hole to the outside of the outer casing. This allows for direct contact between the contact portion and human skin, which helps improve the accuracy of skin temperature measurement.

[0027] A second sealing element may be provided on the contact part, which may be interference-fitted with the contact part and the wall of the mounting hole to achieve a waterproof seal.

[0028] In one possible implementation of this application, the skin-contact temperature measurement module may include at least two temperature measurement modules arranged at intervals. By setting at least two temperature measurement modules, multi-point measurement of skin temperature can be achieved. This allows for mutual calibration between the temperature measurement modules, improving the measurement accuracy of the skin temperature by the skin-contact temperature measurement module, and thus improving the human body temperature measurement accuracy of the wearable device.

[0066] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0067] To facilitate understanding of the wearable device provided in this application embodiment, its application scenarios are first described below. This wearable device can be, but is not limited to, portable electronic devices such as smartwatches and smart bracelets. Taking a smartwatch as an example, it can be worn on the user's wrist to detect the user's body temperature and other vital signs at any time, thereby enabling prediction of the user's physical condition and effectively reducing the risk of dangerous illnesses.

[0068] Currently, smartwatches with body temperature measurement functions can be divided into two main categories in terms of their temperature measurement modules: one is the non-contact temperature measurement module, represented by infrared thermometry. This type of module has a more complex structure, higher cost, and requires more space for installation, making it more difficult to implement. Furthermore, infrared-based non-contact temperature measurement modules typically occupy space within the smartwatch's casing to emit infrared light. This can negatively impact the smartwatch's aesthetic appearance.

[0069] Another type of temperature measurement module typically involves creating an opening in the housing to house the temperature sensor; alternatively, a simple heat-conducting column connected to the temperature sensor extends from the opening to measure the temperature. This approach suffers from significant measurement errors due to variations in the thermal conductivity of the housing and the considerable influence of the environment. Furthermore, placing the temperature sensor inside an opening in the housing complicates the waterproofing of wearable products. Encasing the temperature sensor in a seal further increases the likelihood of measurement errors.

[0070] As explained above, most smartwatches with temperature measurement modules currently measure the temperature of the skin on the wrist. However, wrist skin temperature and body temperature are not the same thing, and the measurement of wrist skin temperature is greatly affected by the ambient temperature. Therefore, wrist skin temperature cannot accurately reflect body temperature.

[0071] Based on this, this application provides a wearable device that simultaneously sets up an ambient temperature measurement module and a skin-touch temperature measurement module to input the obtained ambient temperature data and skin temperature data into an algorithm, thereby obtaining a relatively accurate human body temperature measurement result.

[0072] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0073] The terminology used in the following embodiments is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. As used in the specification and appended claims of this application, the singular expressions “a,” “an,” “the,” “the,” and “this” are intended to also include expressions such as “one or more,” unless the context clearly indicates otherwise. It should also be understood that in the following embodiments of this application, “at least one” and “one or more” refer to one, two, or more than two. The term “and / or” is used to describe the relationship between related objects, indicating that three relationships may exist; for example, A and / or B can indicate: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character “ / ” generally indicates that the preceding and following related objects are in an “or” relationship.

[0074] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0075] In this application, the algorithm used to calculate human body temperature plays a crucial role in enabling the wearable device to perform temperature measurement. When the wearable device provided in this application is under development, it can simultaneously collect ambient temperature data from the environmental temperature measurement module, skin data from the skin-touch temperature measurement module, and accurate human body temperature data from the same object. Taking into account individual differences of the collected objects, such as age and gender, the algorithm is trained to finally achieve its function.

[0076] Reference Figure 1 , Figure 1 The flowchart illustrates the calculation process for obtaining human body temperature using an algorithm. It can be understood that in this algorithm, the ambient temperature data T1 measured by the ambient temperature measurement module and the skin temperature data T2 measured by the skin-touch temperature measurement module are the inputs to the algorithm, while the human body temperature data T3 is the output.

[0077] Additionally, refer to Figure 2 , Figure 2 This paper illustrates a human body temperature curve obtained using the algorithm described above, according to one embodiment of this application. Figure 2In the diagram, the ambient temperature data T1 measured by the environmental temperature measurement module is represented by a curve with a diamond shape, the skin temperature data T2 measured by the skin-contact temperature measurement module is represented by a curve with a square shape, and the human body temperature data T3 obtained through the algorithm is represented by a curve with a triangle shape. Figure 2 As can be seen, the curve of human body temperature data T3 obtained by using the algorithm of this application through the calculation of multiple sets of corresponding environmental temperature data T1 and skin temperature data T2 is relatively flat, which proves the practicality and reliability of the algorithm.

[0078] After gaining a preliminary understanding of the principle of human body temperature measurement in the wearable device provided in this application, the following section, in conjunction with the accompanying drawings, introduces the specific setup of the environmental temperature measurement module and the skin-touch temperature measurement module in the wearable device.

[0079] Reference Figure 3 , Figure 3 This is a schematic diagram of the structure of a wearable device provided in one embodiment of this application. In this application, a smartwatch is used as an example to describe the wearable device capable of body temperature measurement.

[0080] exist Figure 3 In the illustrated embodiment, the wearable device may include a housing 1 having a first housing 101 and a second housing 102. The first housing 101 and the second housing 102 are engaged to form a receiving space 103 between the first housing 101 and the second housing 102 for accommodating the functional modules of the wearable device.

[0081] Additionally, the first housing 101 may include a first surface 1011. In this application, the first surface 1011 may be the surface that contacts the human body when the wearable device is worn. The second housing 102 may include a second surface (not shown in the figure), which is disposed opposite to the first surface 1011. In one possible embodiment of this application, the second surface may be the surface of a display screen, which can be used to display the results measured by the functional modules of the wearable device. It is understood that in Figure 3 In order to show the housing space 103 of the outer casing 1, the display screen is omitted.

[0082] A connecting wall 1021 is also provided between the first surface 1011 and the second surface, which is used to connect the first surface 1011 and the second surface. Furthermore, the connecting wall 1021 can be disposed either in the first housing 101 or the second housing 102. It is understood that, in this application, the second surface and the connecting wall 1021 can serve as the exterior surfaces of the wearable device.

[0083] You can continue to refer to Figure 3The wearable device may also include a button 2. In one embodiment of this application, the button 2 may be disposed on the outer surface of the wearable device. Exemplarily, it may be disposed on the second surface or the connecting wall 1021. Figure 3 In the embodiment shown, button 2 is located on the connecting wall 1021, which facilitates the narrow bezel design of the display screen of the wearable device.

[0084] In this application, when specifically setting button 2, please refer to... Figure 4 , Figure 4 A schematic diagram of a button 2 according to an embodiment of this application is shown. The button 2 may include a button cap 201 and a button lever 202 connected together. The button cap 201 may be, but is not limited to, circular, elliptical, or rectangular shapes. Additionally, see also... Figure 3 and Figure 4 At least a portion of the button cap 201 extends from the connecting wall 1021 to the outside of the housing 1 and comes into contact with the external environment to facilitate operation of the button 2. The button lever 202 extends into the interior of the receiving space 103 of the housing 1 and can be used to connect with functional modules within the receiving space 103.

[0085] The button 2 of the wearable device provided in this application can be set as... Figure 3 The illustrated embodiment features a press button, allowing control of the corresponding function of the functional module by pressing the button cap 201. In other embodiments, for example... Figure 5 In the wearable device shown, button 2 can also be configured as a rotary button, allowing control of the corresponding function of the functional module by rotating button 2. It is understood that the above are merely exemplary descriptions of the button 2 configuration in this application. In other embodiments of this application, button 2 may also adopt other possible configurations, such as simultaneously including the functions of a press button and a rotary button, which will not be described in detail here. Furthermore, a clearance space is reserved within the accommodating space 103 for linear reciprocating or rotating movements of the button. It should be understood that in this application, there is no necessary connection between the shape of the button cap 201 and the specific configuration of button 2. For example, a button 2 with a circular button cap 201 can be either a press button or a rotary button; a button 2 with an elliptical button cap 201 can be either a press button or a rotary button. For ease of distinction, in the following embodiments of this application, button 2 used to control the functional module will be referred to as function button 2a.

[0086] As described above regarding the principle of human body temperature measurement in wearable devices, the wearable device provided in this application may include an ambient temperature measurement module. In one possible embodiment, this ambient temperature measurement module may be integrated with the function button 2a of the wearable device.

[0087] In specific implementation, since the button cap 201 can come into contact with the external environment, in this embodiment, the button cap 201 can be made of a material with a high thermal conductivity, so that the button cap 201, as the first heat-conducting end, can exchange heat with the external environment to achieve the purpose of collecting ambient temperature information. In one possible embodiment of this application, the material of the button cap 201 can be, for example, a metal such as aluminum, copper alloy, or stainless steel, or a non-metal such as high thermal conductivity ceramic, sapphire, or high thermal conductivity plastic. In addition, in this application, the button lever 202 can also be made of a material with a high thermal conductivity, for example, a metal such as aluminum, copper alloy, or stainless steel, or a non-metal such as high thermal conductivity ceramic, sapphire, or high thermal conductivity plastic, so that heat can be transferred between the button cap 201 and the button lever 202. It is understood that in this application, the materials of the button cap 201 and the button lever 202 can be the same or different, as long as efficient heat transfer can be achieved between the two.

[0088] Reference Figure 6a , Figure 6a A cross-sectional view of a function key 2a according to one embodiment of this application is shown. In this embodiment, the structure of the function key 2a can be the same as described above. Figure 4 The structure of button 2 shown is the same, then Figure 6a Showing Figure 4 The cross-sectional structure at point AA. This function button 2a can be a one-piece molded structure, formed by, but not limited to, multi-shot injection molding, multi-shot casting, three-dimensional additive manufacturing, or powder metallurgy. Alternatively, this function button 2a can also be an assembled structure, wherein the button cap 201 and the button rod 202 can be fixedly connected by, but not limited to, welding, bonding, riveting, snap-fitting, or threaded connections.

[0089] In some embodiments of this application, the button cap 201 and / or the button lever 202 may also employ an inner and outer layer structure design. For example, in... Figure 6a In the illustrated embodiment, both the button cap 201 and the button lever 202 are designed with inner and outer layers. The inner and outer layer structures can be categorized as: fully enclosed outer layer, partially enclosed outer layer, or surface patch outer layer. Figure 6a In the illustrated embodiment, the button cap 201 adopts a semi-enclosed outer layer design, and the button lever 202 adopts a fully enclosed outer layer design. Specifically, the inner layer portion 2032a of the button cap 201 has at least two surfaces in contact with the outer layer portion 2031a, and at least one surface is located outside the outer layer portion 2031a. The outer layer portion 2031b of the button lever 202 forms a closed space, and the inner layer portion 2032b is completely surrounded by the outer layer portion 2031b within this closed space. Therefore, when the fully enclosed outer layer design is adopted, none of the surfaces of the inner layer portion 2032b contact the external space or external components.

[0090] In other embodiments, both the button cap 201 and the button lever 202 may adopt a semi-enclosed or fully enclosed design. The specific configuration is similar to the embodiments described above and will not be repeated here.

[0091] Reference Figure 6b , Figure 6b A cross-sectional structural diagram of a button with a surface mount design (201) is shown. In this embodiment, only one side of the inner layer 2032 of the button cap 201 contacts the outer layer 2031, while the remaining sides are located outside the outer layer 2031. Furthermore, it is worth mentioning that... Figure 6b In the illustrated embodiment, the button lever 202 adopts a one-piece molded structure design, which can be formed by methods such as injection molding, injection casting, three-dimensional additive manufacturing, or powder metallurgy. Furthermore, the button lever 202 and the button cap 201 can be a one-piece molded structure, and the molding method can be, but is not limited to, injection molding, injection casting, three-dimensional additive manufacturing, or powder metallurgy. Alternatively, the button lever 202 and the button cap 201 can be assembled by, but is not limited to, welding, bonding, snap-fitting, or threaded connections.

[0092] As described in the above embodiments, the function key 2a provided in this application can possess high thermal conductivity. When the key cap 201 and / or the key lever 202 adopt an inner and outer layer structure design, both the inner layer 2032 and the outer layer 2031 can possess high thermal conductivity. Specifically, for example, the outer layer 2031 can be made of metals with high thermal conductivity, such as aluminum alloy or stainless steel, or materials with high thermal conductivity, such as ceramics, sapphire, or plastics. The thermal conductivity of the outer layer 2031 made of the above materials is approximately 35-200 W / (m·K), which allows the outer layer 2031 to possess high thermal conductivity while also having relatively reliable structural stability, thereby meeting the structural strength requirements of the entire function key 2a. Furthermore, the surface of the outer layer 2031 can have surface treatment features including, but not limited to, polishing, painting, brushing, or matte finishes to improve the aesthetic appearance of the function key 2a.

[0093] Since at least a portion of the inner layer 2032 can be covered by the outer layer 2031, its structural strength has a relatively small impact on the overall structural stability of the function button 2a. Therefore, in this application, the inner layer 2032 can be made of copper or a copper alloy with high thermal conductivity. Since the thermal conductivity of copper or copper alloy is approximately 200-380 W / (m·K), its thermal conductivity is high, 5-10 times that of ordinary metal materials. Therefore, the thermal conductivity of the inner layer 2032 using this material can reach 200-380 W / (m·K). In this application, by setting the button cap 201 and / or button lever 202 of the function button 2a as an inner and outer layer structure, the overall thermal conductivity of the button can be effectively improved.

[0094] In one possible embodiment of this application, the molding method for the function key 2a can be, but is not limited to, two-shot injection molding, two-shot casting injection molding, three-dimensional additive manufacturing, or powder metallurgy. Using the above molding methods, the materials of the keycap 201 and / or the key lever 202 can be manufactured in layers, and the inner layer 2032 and the outer layer 2031 can be bonded together. Furthermore, subsequent CNC machining, surface treatment, and other processes can ensure the appearance, mechanical properties, and high thermal conductivity of the function key 2a.

[0095] In the above embodiments, the specific design of the function button 2a is described using it as the assembly structure. In other embodiments of this application, the function button 2a can also be a one-piece molded structure. In this embodiment, if the button cap 201 and the button rod 202 adopt an inner and outer layer structure design, the inner layer 2032 of both can be a one-piece molded structure, and the outer layer 2031 of both can also be a one-piece molded structure. This can effectively simplify the structure and processing technology of the button, thereby improving the processing efficiency of the button.

[0096] Reference Figure 7 , Figure 7 An exploded structural diagram of a wearable device according to another embodiment of this application is shown. To facilitate the explanation of the connection and positional relationship between the ambient temperature measurement module and function button 2a, in... Figure 7 The outer casing of the wearable device is omitted. In this embodiment of the application, the ambient temperature measurement module is disposed as follows: Figure 3The wearable device shown is housed within the housing 103 of its outer shell 1, which protects the ambient temperature measurement module and improves the structural reliability of the wearable device. The ambient temperature measurement module may include a first temperature sensor 301 and a first circuit board assembly 302. The first temperature sensor 301 is fixed to the end of the button lever 202 facing away from the button cap 201, making this end of the button lever 202 a second heat-conducting end. It is understood that the portion of the button lever 202 used to connect the first and second heat-conducting ends can serve as a connecting part. Thus, the ambient temperature collected by the button cap 201 (serving as the first heat-conducting end) can be transferred to the second heat-conducting end via the connecting part of the button lever 202, and then to the first temperature sensor 301 located at the second heat-conducting end. To improve the thermal conductivity between the first temperature sensor 301 and the button lever 202, the first temperature sensor 301 can be bonded to the end of the button lever 202 using thermally conductive adhesive 303.

[0097] You can continue to refer to Figure 7 A flat mounting surface 2021 of a certain size can be provided at the end of the button lever 202 away from the button cap 201 (the second heat-conducting end). This surface provides a mounting plane for the first temperature sensor 301 to be mounted on the button lever 202, thereby facilitating the installation and fixation of the first temperature sensor 301. Furthermore, the area of ​​the mounting plane can be adjusted to increase the contact area between the second heat-conducting end and the first temperature sensor 301, thereby improving the accuracy of the ambient temperature received by the first temperature sensor 301.

[0098] You can continue to refer to Figure 7 The first circuit board assembly 302 may include a first circuit board 3021, which may be, for example, a flexible printed circuit (FPC), facilitating its placement within the housing 1 of the wearable device. It is understood that, in some possible embodiments of this application, the first circuit board 3021 may also be a printed circuit board (PCB), which may be applied, for example, to wearable devices with ample accommodating space 103 within the housing 1.

[0099] The first circuit board 3021 is electrically connected to the first temperature sensor 301, and the ambient temperature signal detected by the first temperature sensor 301 can be transmitted to the first circuit board 3021. Specifically, in... Figure 7In the illustrated embodiment, the first circuit board 3021 can be disposed on the side of the first temperature sensor 301 opposite to the button lever 202. However, in other embodiments of this application, the first circuit board 3021 can also be disposed between the first temperature sensor 301 and the button lever 202, in which case the first circuit board 3021 can be fixed to the button lever 202 by thermally conductive adhesive 303. In this application, by disposing the first temperature sensor 301 and the first circuit board 3021 at the end of the button lever 202 opposite to the button cap 201, the outer shell of the wearable device can protect the first temperature sensor 301 and the first circuit board 3021, thereby effectively improving the stability of the ambient temperature measurement module for ambient temperature acquisition.

[0100] The above embodiments are merely illustrative examples illustrating the relative positional relationship between the first circuit board 3021, the first temperature sensor 301, and the button lever 202. Furthermore, those skilled in the art can reasonably arrange the first temperature sensor 301 according to its type and the connection process between the first temperature sensor 301 and the first circuit board 3021, but all such arrangements should be understood to fall within the protection scope of this application.

[0101] In addition, a button rubber pad 3022 and a button spring 3023 may be provided on the first circuit board 3021, including but not limited to the button rubber pad 3022, wherein the button rubber pad 3022 can be used to buffer, and the button spring 3023 can be used as a switch for the function button 2a.

[0102] In one possible embodiment of this application, to ensure a stable connection between the first circuit board 3021, the first temperature sensor 301, and the button lever 202, the ambient temperature measurement module may further include a cover plate 304. Figure 7 It can be seen that the cover plate 304 can lock and fix the assembled first circuit board 3021, first temperature sensor 301, and button lever 202. In specific implementations, the cover plate 304 can have an inner contour that matches the outer contour of the assembly structure formed by connecting the ends of the first circuit board 3021, first temperature sensor 301, and button lever 202 away from the button cap 201. This allows the cover plate 304 to be fitted onto the assembly structure, thereby giving the cover plate 304 superior fixing and protective capabilities, and the cover plate 304 in... Figure 3 The space occupied within the housing 103 of the wearable device shown is smaller. It is worth mentioning that, in the embodiments of this application, the cover plate 304 may be, but is not limited to, an injection molded part obtained by injection molding process, or a metal part obtained by metal processing process (such as stamping). The processing technology and material of the cover plate 304 are not limited in this application.

[0103] Additionally, you can continue to refer to Figure 7 In one possible embodiment of this application, the cover plate 304 can also be bonded to at least one of the first circuit board 3021, the first temperature sensor 301 and the button lever 202 by adhesive material 305, thereby effectively improving the connection reliability of the structure formed by assembling the cover plate 304 with the first circuit board 3021, the first temperature sensor 301 and the button lever 202.

[0104] Reference Figure 8 , Figure 8 for Figure 7 The diagram shows a partial structural schematic of the function button 2a and the ambient temperature measurement module installed after mounting on the housing 1. Figure 8 The image shows the relative positional relationship between the button rubber pad 3022 and the button spring 3023 and the function button. The button rubber pad 3022 can be located between the function button and the button spring 3023 to provide a buffering effect.

[0105] Continue to refer to Figure 8 In some embodiments of this application, a waterproof groove 2022 may be provided on the button lever 202 of the function button 2a. This waterproof groove 2022 may be an annular groove surrounding the button lever 202. Furthermore, a first sealing element 205 may be installed within the waterproof groove 2022. This first sealing element 205 may be, but is not limited to, a sealing element such as... Figure 4 The annular rubber ring shown is illustrated. It is understood that the first seal 205 can be interference-fitted with the button lever 202 and the side wall of the housing 1 or the structural components within the housing 1's accommodating space to achieve a waterproof seal. The interference fit between the first seal 205 and the button lever 202 and the side wall of the housing 1 or the structural components within the housing 1 can be, but is not limited to, interference fit, abutment, or embedding.

[0106] It is worth mentioning that, Figure 7 and Figure 8 In the illustrated embodiment, function button 2a can be configured as a push button. The button may further include an elastic element 204, which can be disposed on the side of the button cap 201 facing the button lever 202. The elastic element 204 can, but is not limited to, elastically abut against the housing 1 or a structural member disposed within the receiving space. Thus, when function button 2a is pressed, the elastic element 204 accumulates elastic force, and when function button 2a is released, the elastic element 204 releases the elastic force, thereby pushing function button 2a to reset. Furthermore, the elastic element 204 can, but is not limited to, be a spring, and the spring constant and number of springs can be designed according to specific elasticity requirements.

[0107] As can be seen from the above description of the outer shell 1 of the wearable device, in this application, the first surface 1011 of the first housing 101 of the outer shell 1 can be used as the surface of the wearable device in contact with the human body, and the skin-contact temperature measurement module can be used to measure the skin temperature of the human body. Therefore, the skin-contact temperature measurement module can be set in the first housing 101.

[0108] Reference Figure 9 , Figure 9 A schematic diagram of the structure of a first housing 101 according to one embodiment of this application is provided. In this embodiment, the wearable device is provided with a photoplethysmograph (PPG) module, which includes a PPG lens 5 disposed on the first housing 101. In this application, the specific shape of the PPG lens 5 is not limited. For example, the PPG lens 5 can be circular, rectangular, or any other regular or irregular shape.

[0109] In this embodiment, the PPG lens 5 is embedded or bonded to the first housing 101, and the PPG lens 5 can be part of the first surface 1011 for contact with the skin of the wearing area. Since the material of the PPG lens 5 is typically sapphire, which has good thermal conductivity (approximately 35-55 W / (m·K)), the PPG lens 5 can be used for skin temperature acquisition in this embodiment. Furthermore, this application does not limit the specific location of the PPG lens 5 on the first housing 101. For example, it can be positioned at the center of the first housing 101 to effectively increase the contact area between the PPG lens 5 and the wearing area, thereby improving the accuracy of skin temperature acquisition.

[0110] In one possible embodiment of this application, the skin-contact temperature measurement module 4 can be disposed on the PPG lens 5. In this way, human skin temperature information can be efficiently transmitted to the skin-contact temperature measurement module 4 through the PPG lens 5 without the need to add heat-conducting pillars or other heat-conducting structures 6, thereby effectively simplifying the structure of the wearable device.

[0111] Reference Figure 10 , Figure 10 for Figure 9 A magnified view of the partial structure at point B. In this embodiment, the skin-touch temperature measurement module 4 may include a second temperature sensor 401 and a second circuit board assembly 402. The second temperature sensor 401 may be disposed on the PPG lens 5 to efficiently transfer the skin temperature collected by the PPG lens 5 to the second temperature sensor 401. To improve the thermal conductivity between the second temperature sensor 401 and the PPG lens 5, the second temperature sensor 401 may be bonded and fixed to the PPG lens 5 using thermally conductive adhesive 303.

[0112] You can continue to refer to Figure 10 In other embodiments of this application, the PPG lens 5 can be divided into a light-transmitting area 501 and a non-light-transmitting area 502. This allows light emitted from the PPG module's light source to pass through the light-transmitting area 501 and enter the human body, or allows light reflected from the human body to pass through the light-transmitting area 501 and be received by the PPG module's photodetector. Furthermore, by adjusting the position of the light source or the emission direction of the light emitted from the light source, as much light as possible can pass through the light-transmitting area 501 for transmission, thereby reducing energy loss and improving the detection accuracy of the PPG module.

[0113] It is understood that, in this embodiment of the application, the second temperature sensor 401 can be disposed in the non-transparent area 502 of the PPG lens 5, thereby avoiding the second temperature sensor 401 from blocking the light emitted or reflected by the light source.

[0114] When specifically configuring the second circuit board assembly 402, please refer to... Figure 10 The second circuit board assembly 402 may include a second circuit board 4021, which may be, for example, a flexible printed circuit board (FPC), thus facilitating the installation of the second circuit board 4021. Figure 3 The layout within the housing 1 of the wearable device is shown. It is understood that, in some possible embodiments of this application, the second circuit board 4021 may also be a printed circuit board (PCB), which can be exemplary applied in wearable devices with ample accommodating space 103 in the housing 1.

[0115] Reference Figure 11 , Figure 11 Showing Figure 10 A cross-sectional view of the CC section is shown. In this embodiment of the application, the second circuit board 4021 is electrically connected to the second temperature sensor 401. Wherein... Figure 11In the illustrated embodiment, the second circuit board 4021 can be disposed on the side of the second temperature sensor 401 facing away from the PPG lens 5. However, in other embodiments of this application, the second circuit board 4021 can also be disposed between the second temperature sensor 401 and the PPG lens 5, in which case the second circuit board 4021 can be fixed to the PPG lens 5 by thermally conductive adhesive 303. The above embodiments are merely illustrative examples of the relative positional relationship between the second circuit board 4021, the second temperature sensor 401, and the PPG lens 5. Furthermore, those skilled in the art can reasonably arrange the second temperature sensor 401 according to its type and the connection process between the second temperature sensor 401 and the second circuit board 4021, but all such arrangements should be understood to fall within the protection scope of this application.

[0116] It is worth mentioning that, but not limited to, a button rubber pad may be provided on the second circuit board 4021 to buffer the second circuit board 4021.

[0117] In addition, in some possible embodiments, the second circuit board 4021 may be the same circuit board as the first circuit board 3021 in the above embodiments, so as to effectively simplify the structure of the wearable device and allow the housing 103 to have extra space for installing other functional modules, thereby realizing the functional diversification design of the wearable device.

[0118] It is understood that the PPG lens and skin-contact temperature measurement module 4 provided in the above embodiments can not only be disposed in the first housing 101. Figure 9 In addition to wearable devices of the shape shown, they can also be set in, but are not limited to, devices such as Figure 12 Wearable devices of the shape shown. Additionally, see reference... Figure 13 , Figure 13 Showing Figure 12 The structure of the first housing 101 of the wearable device shown in the figure, in this embodiment, the specific arrangement of the PPG lens and the skin-contact temperature measurement module 4 can be referred to Figure 9 The embodiments shown are not described in detail here.

[0119] Reference Figure 14 , Figure 14 This illustration demonstrates another possible embodiment of the skin-contact temperature measurement module 4. In this embodiment, the placement of the skin-contact temperature measurement module 4 is independent of the design of the PPG lens 5. Specifically, the skin-contact temperature measurement module 4 may include one temperature measuring structure 403; or it may include at least two temperature measuring structures 403, such as... Figure 14As shown, the at least two temperature measuring structures 403 can be, but are not limited to, disposed around the periphery of the PPG lens 5, and arranged at intervals. Their arrangement can be, but is not limited to, symmetrical or matrix arrangement. This allows for algorithm optimization through multi-point skin temperature measurement, thereby improving the accuracy of human body temperature measurement.

[0120] Reference Figure 15 , Figure 15 This is a schematic diagram of a possible embodiment of the temperature measuring structure 403 of this application. The temperature measuring structure 403 may include a heat-conducting element 4031, which includes a fixing part 40311 and a contact part 40312. The fixing part 40311 and the contact part 40312 may be integrally formed; or the fixing part 40311 and the contact part 40312 may be independent structures, and they may be connected by, but not limited to, two-shot injection molding, multi-shot casting, three-dimensional additive manufacturing, or powder metallurgy. Alternatively, they may be assembled by bonding, welding, or threaded connections. Furthermore, the fixing part 40311 and the contact part 40312 may be made of a single material, or they may be configured as an inner and outer layer structure. When an inner and outer layer structure design is adopted, the specific configuration and material selection can be referred to the description of the function buttons using an inner and outer layer structure design in the above embodiments, and will not be repeated here.

[0121] In this embodiment of the application, the fixing part 40311 can be used with... Figure 14 The wearable device shown is fixedly connected to the outer shell 1, thereby achieving a fixed connection between the heat-conducting component 4031 and the outer shell 1. It can be understood that when the heat-conducting component 4031 is installed on the outer shell 1, the fixing part 40311 can be located in the receiving space 103 of the outer shell 1 (see reference). Figure 3 The fixing part 40311 is fixedly connected to the outer shell 1. For example, the fixing part 40311 can be fixed to one side of the first surface 1011 located in the receiving space 103.

[0122] Additionally, you can refer to the following: Figure 14 and Figure 15 A mounting hole 1012 may be provided on the first housing 101, the mounting hole 1012 penetrating the first surface 1011. At least a portion of the contact portion 40312 extends from the mounting hole 1012 to the outside of the housing 1 for contact with the skin of the wearing area. (See also...) Figure 15A second sealing element 40313 may also be provided on the contact portion 40312. This second sealing element 40313 may be, for example, an annular rubber ring. The second sealing element 40313 can be fitted with the contact portion 40312 and the wall of the mounting hole 1012 through interference, thereby achieving a waterproof sealing effect. It is understood that, in this embodiment of the application, the portion of the first housing 101 used for housing the heat-conducting element 4031 may be made of a material with low thermal conductivity, such as plastic, to reduce its impact on the temperature acquisition of the heat-conducting element 4031.

[0123] The temperature measuring structure 403 may further include a second circuit board 4021, which is fixed to the side of the fixing part 40311 opposite to the contact part 40312 by thermally conductive adhesive 303. Additionally, a second temperature sensor 401 is disposed on the second circuit board 4021, and the second temperature sensor 401 may, but is not limited to, be fixed to the second circuit board 4021 by thermally conductive adhesive 303. In this way, the skin temperature collected by the contact part 40312 can be transmitted to the second temperature sensor 401 through the fixing part 40311 and the second circuit board 4021. (Continuing to refer to...) Figure 15 In some possible embodiments of this application, the second circuit board 4021 can be connected to the contact portion 40312 and the fixing portion 40311 respectively through thermally conductive adhesive 303. This allows the skin temperature collected through the contact portion 40312 to be directly transferred to the second circuit board 4021, which helps to improve the accuracy of temperature measurement.

[0124] In another possible embodiment of this application, the second temperature sensor 401 can be fixed to the heat-conducting component 4031 using thermally conductive adhesive 303, and the second circuit board 4021 can be fixed to the second temperature sensor 401 using thermally conductive adhesive 303. Those skilled in the art can make reasonable arrangements based on the type of the selected second temperature sensor 401 and the connection process between the second temperature sensor 401 and the second circuit board 4021, but all of these should be understood to fall within the protection scope of this application.

[0125] Continue to refer to Figure 15 A stop portion 403111 may also be provided on the side of the fixing portion 40311 of the heat-conducting component 4031 away from the contact portion 40312. There may be two stop portions 403111 arranged opposite each other. The structures such as the second temperature sensor 401 and the second circuit board 4021 that are connected to the heat-conducting component 4031 may be provided between the two stop portions 403111, thereby limiting the two temperature sensors 401 and the second circuit board 4021 on the fixing portion 40311.

[0126] As described above regarding the temperature measuring structure 403, in some embodiments of this application, each temperature measuring structure 403 may be provided with a second circuit board 4021 and a second temperature sensor 401. In other embodiments, each temperature measuring structure 403 may be provided with a second temperature sensor 401, and at least two temperature measuring structures 403 may share a single second circuit board 4021. This effectively simplifies the structure of the skin-contact measurement module. By employing multiple temperature measuring structures 403 to simultaneously measure skin temperature, the accuracy of skin temperature measurement can be effectively improved, thereby enhancing the precision of human body temperature measurement.

[0127] Understandably, in Figure 14 and Figure 15 In the illustrated embodiment, the contact portion 40312 of the temperature sensing structure 403 has a rectangular outline design. In other embodiments of this application, the contact portion 40312 may also adopt a rectangular outline design. Figure 16 The multi-segment arc-shaped contour design shown, or the use of Figure 17 The circular outline design shown can, of course, also be used in other shapes such as petals, which will not be listed here.

[0128] In the above embodiments of this application, the button used to set the ambient temperature measurement module can control the functional modules of the wearable device through pressing or rotating operations. In some other possible embodiments of this application, the button used to connect to the ambient temperature measurement module can be designed separately. In this embodiment, the button is not connected to any other functional modules except for collecting ambient temperature data, and pressing or rotating the button cannot be used to perform any function. In this application, such a button can be referred to as a "dummy button".

[0129] To improve the aesthetics of wearable devices and avoid interfering with the operation of function buttons, the length of the part of the button cap 201 of the dummy button 2b extending outside the housing 1 can be reduced. For example, refer to... Figure 18 , Figure 18 This invention illustrates an embodiment of the dummy button 2b in a wearable device. In this embodiment, the surface of the button cap 201 of the dummy button 2b is designed to adapt to the surface contour of the connecting wall 1012 of the outer shell 1, thereby improving the continuity of the surface contour of the wearable device and enhancing its appearance.

[0130] Reference Figure 19 , Figure 19 for Figure 18The diagram shows an exploded view of the wearable device. In this embodiment, the elastic element may not be provided on the button cap 201, thereby simplifying the structure of the wearable device. The structure and material selection of the button cap 201 and button lever 202 of the dummy button 2b can be set with reference to the function buttons in the above embodiment, and will not be described in detail here.

[0131] You can continue to refer to Figure 19 A through hole 1022 can also be provided on the connecting wall 1012, through which the button rod 202 of the dummy button 2b can extend into the receiving space 103. In some embodiments of this application, the length of the button rod 202 extending into the receiving space 103 can be shortened as much as possible. In specific implementation, such as... Figure 20 As shown, Figure 20 for Figure 18 The diagram shows a partial structural schematic of the wearable device. In this embodiment, the button cap 201 and / or button lever 202 can be miniaturized, which can reduce the space occupied by the dummy button 2b in the housing space 103.

[0132] Understandable, Figures 18 to 20 The ambient temperature measurement module, skin-touch temperature measurement module, and method for measuring human body temperature shown in the embodiments can all be configured with reference to any of the above embodiments, and will not be described in detail here.

[0133] As can be seen from the above embodiments describing the specific setup of the ambient temperature measurement module in a wearable device, as long as the ambient temperature can be conducted to the ambient temperature measurement module through a heat-conducting structure, the module can acquire the ambient temperature. Therefore, in addition to the buttons (function buttons or dummy buttons) mentioned in the above embodiments, in other embodiments of this application, the heat-conducting structure can also be hidden within the outer casing to avoid affecting the aesthetic appearance of the wearable device.

[0134] In specific implementation, refer to Figure 21 , Figure 21 A schematic diagram of a possible embodiment of the heat-conducting structure 6 of this application is shown. In this embodiment, the heat-conducting structure 6 may include a first heat-conducting end 601, a second heat-conducting end 602, and a connecting portion 603 for connecting the first heat-conducting end 601 and the second heat-conducting end 602. The first heat-conducting end 601 can be used to collect ambient temperature, so that the ambient temperature can be... Figure 21 The arrow shown is transmitted from the first heat-conducting end 601 through the connecting part 603 to the second heat-conducting end 602.

[0135] In this embodiment of the application, the heat-conducting structure 6 can be an integrally molded structure or an inner and outer layer structure design. The specific setting method and material selection can refer to the function buttons described in the above embodiments, and will not be repeated here.

[0136] When installing the heat-conducting structure 6 on the outer casing 1, refer to Figure 22a , Figure 22a This is a schematic diagram of the structure of a wearable device according to another embodiment of this application. The first heat-conducting end 601 of the heat-conducting structure 6 can extend into the connecting wall 1012 of the outer shell 1, so that the ambient temperature collected by the first heat-conducting end 601 is closer to the ambient temperature outside the wearable device, thereby improving the accuracy of human body temperature measurement of the wearable device.

[0137] You can continue to refer to Figure 22a ,exist Figure 22a In the illustrated embodiment, the first heat-conducting end 601 extends into the button slot 104 of the housing 1, which is used to mount a button (function button or dummy button). It is understood that in this embodiment, the button slot 104 may be provided with a clearance space to avoid interference between the button and the first heat-conducting end 601, allowing the button and the first heat-conducting end 601 to each perform their respective functions. Furthermore, by placing the first heat-conducting end 601 within the button slot 104, the structure and manufacturing process of the housing 1 can be effectively simplified.

[0138] Since the first heat-conducting end 601 of the heat-conducting structure 6 can extend into the key slot 104, and the second heat-conducting end 602 is located within the receiving space 103. (See also...) Figure 21 and Figure 22a In one possible embodiment of this application, a hollow area 6031 may also be provided in the connection portion 603 of the heat-conducting structure 6. This hollow area 6031 can be used to avoid the button lever of the button, thereby preventing interference with the operation of the button. Additionally, in Figure 21 and Figure 22a In the embodiment shown, the first heat-conducting end 601 can also be set as two, and the two first heat-conducting ends 601 are respectively disposed on both sides of the hollow area 6031 to increase the area of ​​the heat-conducting structure 6 for contact with the external environment and improve its accuracy in collecting ambient temperature.

[0139] Reference Figure 22b , Figure 22bThis demonstrates the wearable device's structure from another angle. The second heat-conducting end 602 of the heat-conducting structure 6 can extend into the receiving space 103 of the outer shell 1, allowing the ambient temperature measurement module to be fixed to the second heat-conducting end 602. This enables the ambient temperature collected by the first heat-conducting end 601 to be transferred to the ambient temperature measurement module via the connecting part 603 and the second heat-conducting end 602. To improve the thermal conductivity between the ambient temperature measurement module and the second heat-conducting end 602, the ambient temperature measurement module can be bonded to the second heat-conducting end 602 using thermally conductive adhesive. Further details can be found by referring to… Figure 22b The second heat-conducting end 602 can also be provided with a flat mounting surface of a certain size. This mounting surface can provide a mounting plane for the installation of the ambient temperature measurement module on the heat-conducting structure 6, thereby facilitating the installation and fixation of the ambient temperature measurement module.

[0140] It is worth mentioning that, in order to improve the structural stability of the wearable device's casing 1 and facilitate the arrangement of functional modules within the storage space 103, reference can be made to... Figure 22b A bracket 105 may also be provided on one side of the connecting wall 1012 of the outer casing 1 located within the accommodating space 103. The bracket 105 is fixedly connected to the connecting wall 1012 so that the bracket 105 supports the connecting wall 1012.

[0141] Reference Figure 23 , Figure 23 The relative positional relationship between the heat-conducting structure 6, the connecting wall 1012, and the support 105 is illustrated. The connecting portion of the heat-conducting structure 6 can be embedded in the support 105, thus concealing the connecting portion of the heat-conducting structure 6 within the support 105, which reduces the space occupied by the heat-conducting structure 6 in the accommodating space 103. Furthermore, by embedding the heat-conducting structure 6 in the support 105, the support 105 can also support the heat-conducting structure 6, reducing the need for considerations regarding the structural strength of the heat-conducting structure 6. This allows the heat-conducting structure 6 to be made of a material with a high thermal conductivity, thereby improving its temperature detection accuracy. It is understood that, in order to conceal the heat-conducting structure 6 within the connecting wall 1012 and the support 105, the heat-conducting structure 6 can be manufactured using, but is not limited to, insert injection molding.

[0142] exist Figure 23In the illustrated embodiment, the first circuit board 3021 of the ambient temperature measurement module can be fixed to the second heat-conducting end 602 by thermally conductive adhesive 303, and the first temperature sensor 301 is disposed on the side of the first circuit board 3021 opposite to the second heat-conducting end 602. Additionally, foam 7 is attached to the surface of the side of the first temperature sensor 301 opposite to the second heat-conducting end 602, which provides protection and shock absorption for the entire ambient temperature measurement module. In other embodiments, the first temperature sensor 301 can be fixed to the second heat-conducting end 602 by thermally conductive adhesive 303, and the first circuit board 3021 can be disposed on the side of the first temperature sensor 301 opposite to the second heat-conducting end 602. In this case, foam 7 can be disposed on the side of the first circuit board 3021 opposite to the second heat-conducting end 602. It is understood that the relative positional relationship between the first circuit board 3021, the first temperature sensor 301 and the second heat-conducting end 602 is not limited in this application. Those skilled in the art can make reasonable arrangements based on the type of the selected first temperature sensor 301 and the connection process between the first temperature sensor 301 and the first circuit board 3021, but all of them should be understood to fall within the protection scope of this application.

[0143] Understandably, in this application, foam 7 can also be attached to the skin-contact temperature measurement module to protect and dampen it. Additionally, Figures 21 to 23 In the embodiments shown, the specific settings of the ambient temperature measurement module, the skin-touch temperature measurement module, and the method for achieving human body temperature measurement can all be set with reference to the above embodiments, and will not be repeated here.

[0144] As described in the above embodiments, in this application, the ambient temperature measurement module can collect the temperature near the connecting wall 1012 to obtain the ambient temperature for obtaining a more accurate human body temperature. Since the side of the connecting wall 1012 facing away from the receiving space 103 is in direct contact with the external environment, in some possible embodiments of this application, the connecting wall 1012 can also be used as a heat-conducting structure. The portion of the connecting wall 1012 located outside the receiving space 103 can serve as the first heat-conducting end, and the portion of the connecting wall 1012 located inside the receiving space 103 can serve as the second heat-conducting end. This effectively simplifies the structure of the wearable device and facilitates the collection of ambient temperature.

[0145] In specific implementation, you can refer to Figure 24 , Figure 24A partial structural schematic diagram of a wearable device according to a possible embodiment of this application is shown. In this embodiment, the connecting wall 1012 may be made of metallic materials such as stainless steel, titanium alloy, aluminum alloy, cobalt-based alloy, nickel-based alloy, iron-based alloy, platinum alloy, and titanium-tanium alloy, or it may be made of non-metallic materials such as ceramic, so that the connecting wall 1012 has a high thermal conductivity.

[0146] The first circuit board 3021 of the ambient temperature measurement module is located on one side of the connecting wall 1012, within the accommodating space 103. The first temperature sensor 301 is fixedly connected to the first circuit board 3021. The first circuit board 3021 can be, for example, a PCB, thus providing support for the first temperature sensor 301. Alternatively, the first temperature sensor 301 can be bonded to the connecting wall 1012 using thermally conductive adhesive. In this case, the first circuit board 3021 simultaneously supports both the first temperature sensor 301 and the thermally conductive adhesive. In this embodiment of the application, the ambient temperature collected by the first thermally conductive end of the connecting wall 1012 can be conducted to the first temperature sensor 301 through the second thermally conductive end and the thermally conductive adhesive. Furthermore, since there is a circuit connection between the first temperature sensor 301 and the first circuit board 3021, temperature data can be transmitted to the first circuit board 3021.

[0147] Understandably, because the connecting wall 1012, which serves as the first heat-conducting end, has a large surface area, its contact area with the environment is also large, which helps to improve the accuracy of the connecting wall 1012 in acquiring ambient temperature. In addition, the overall volume of the connecting wall 1012 is large, therefore, its acquisition of ambient temperature is more stable.

[0148] You can continue to refer to Figure 24 In some other possible embodiments of this application, the minimum distance between the edge of the first circuit board 3021 facing the connecting wall 1012 and the second heat-conducting end of the connecting wall 1012 can be 0.1 mm. This effectively shortens the heat conduction path between the connecting wall 1012 and the first circuit board 3021, thereby improving the accuracy of the ambient temperature data obtained by the first circuit board 3021. Furthermore, by setting a certain distance between the first circuit board 3021 and the second heat-conducting end of the connecting wall 1012, damage to the first circuit board 3021 can be effectively avoided when the connecting wall 1012 is subjected to external force.

[0149] In another embodiment of this application, a certain distance may exist between the first temperature sensor 301 and the connecting wall 1012. For example, the minimum distance between the two is between 0.3-1.3 mm, which can effectively shorten the heat conduction path between the connecting wall 1012 and the first temperature sensor 301, thereby improving the accuracy of the ambient temperature data obtained by the first temperature sensor 301. In addition, by setting a certain distance between the first temperature sensor 301 and the second heat-conducting end of the connecting wall 1012, the risk of damage to the first temperature sensor 301 when the connecting wall 1012 is subjected to external force can be reduced.

[0150] Understandably, in Figure 24 In the embodiments shown, the specific settings of the ambient temperature measurement module, the skin-touch temperature measurement module, and the method for achieving human body temperature measurement can all be set with reference to the above embodiments, and will not be repeated here.

[0151] By using the wearable device provided in this application, and by placing the ambient temperature measurement module on the button 2 or the connecting wall 1012 of the housing 1, a relatively accurate ambient temperature can be obtained through the ambient temperature measurement module. Additionally, a skin-touch temperature measurement module is provided on the first housing 101 to obtain a relatively accurate skin temperature. Thus, the ambient temperature data measured by the ambient temperature measurement module and the skin temperature data measured by the skin-touch temperature measurement module can be used as input values, and the human body temperature can be obtained through algorithm calculation. By comprehensively considering both ambient temperature and skin temperature, the accuracy of human body temperature measurement can be effectively improved.

[0152] It is understood that the scheme for measuring human body temperature provided in the above embodiments of this application can be used not only in wearable devices but also in other commonly used electronic devices. For example, it can be used in mobile phones, speakers, televisions, robot vacuum cleaners, or routers to enable them to measure human body temperature. In these electronic devices, both the ambient temperature measurement module and the skin-contact temperature measurement module can be configured according to any of the above embodiments, and will not be elaborated upon here. Furthermore, through reasonable design, the above electronic devices can also be configured to measure ambient temperature independently.

[0153] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
