Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to a wearable device. Background Art

[0002] With the rapid development of wearable devices, people have more and more requirements for the functions of wearable devices. Among them, measuring body temperature is a very practical function.

[0003] Current wearable devices with body temperature measurement capabilities often use contact-based measurement modules. These contact-based measurement modules can measure temperature by attaching a temperature sensor to the wearable device's housing. However, these modules are susceptible to the thermal conductivity of the housing and the ambient temperature, resulting in significant measurement errors. Summary of the Invention

[0004] The present application provides a wearable device that can measure human body temperature and effectively improves its measurement accuracy.

[0005] The present application provides a wearable device, which may include a shell, a heat-conducting structure, an ambient temperature measurement module and a skin-tight temperature measurement module. The shell includes a first shell and a second shell, and the first shell and the second shell are buckled together to form a storage space of the shell. The first shell includes a first surface, the second shell includes a second surface, and the first surface and the second surface are connected by a connecting wall. The heat-conducting structure includes a first heat-conducting end and a second heat-conducting end, the first heat-conducting end is used to collect ambient temperature, and the second heat-conducting end is located in the storage space. The ambient temperature measurement module is arranged at the second heat-conducting end, and the ambient temperature collected by the first heat-conducting end can be transmitted to the ambient temperature measurement module via the second heat-conducting end to obtain ambient temperature data. The skin-tight temperature measurement module is located in the storage space of the shell and is arranged on the first surface of the first shell for collecting skin temperature. By adopting the solution provided in the present 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 accommodating space, and then conducts it to the ambient temperature measurement module, forming a stable ambient temperature conduction path in the shell, so as to less affect 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-tight temperature measurement module are used as input, and the human body temperature data is obtained through the algorithm, which can effectively improve the accuracy of human body temperature measurement.

[0006] Since wearable devices are usually provided with a button, the button can be provided on the connecting wall of the shell. In a possible implementation of the present application, the heat-conducting structure may be a button, and the button may usually include a button cap and a button rod. The button cap may be provided on the connecting wall to serve as a first heat-conducting end for collecting ambient temperature. The button rod is fixedly connected to the button cap, and the button rod is located in the accommodating space, and the end of the button rod facing away from the button cap serves as the second heat-conducting end for setting the ambient temperature measurement module. In the present application, the collection of ambient temperature is achieved through the button, which can effectively simplify the structure of the wearable device; the ambient temperature measurement module is provided in the shell, so that the ambient temperature measurement module can be protected by the shell.

[0007] When designing the key, the key can be configured as an integrally molded structure, using methods such as, but not limited to, multi-shot injection molding, multi-shot casting, 3D additive manufacturing, or powder metallurgy to enhance the key's structural stability. Alternatively, the key can be configured as an assembled structure, in which case the key cap and key stem can be fixedly connected by, but not limited to, welding, bonding, riveting, clamping, or threaded connection.

[0008] In a possible embodiment of the present application, the key cap and / or key rod may be configured as an inner and outer layer structure. The 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 be in contact with the outer layer portion. The thermal conductivity of the material of the outer layer portion may be 35-200W / (m·K), so that the outer layer portion can have higher thermal conductivity while also having more reliable structural stability, thereby meeting the requirements of the entire key for structural strength. In addition, the surface of the outer layer portion may also have surface treatment features including but not limited to polishing, painting, brushing, or matte, so as to improve the appearance of the key. The thermal conductivity of the material of the inner layer portion may be 200-380W / (m·K), which is beneficial to improving the thermal conductivity efficiency of the entire key.

[0009] In a possible implementation of the present application, the button rod may be provided with a waterproof groove, in which a first sealing member is installed. The first sealing member is interference-fitted with the button rod and the housing, thereby achieving a waterproof seal.

[0010] In a possible implementation of the present application, at least part of the key cap may extend from the connecting wall to the outside of the housing, which can effectively increase the contact area between the key cap and the external environment, thereby facilitating improvement in the accuracy of the key's collection of ambient temperature.

[0011] Furthermore, at least a portion of the keycap extends outside the housing, allowing control of the corresponding function by pressing or rotating the key. If the key is a push key, the key may further include an elastic member disposed on the side of the keycap facing the key stem. Furthermore, the elastic member may elastically abut against the housing or a structural member disposed within the receiving space.

[0012] In one possible implementation of the present 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 the first temperature sensor is electrically connected to the first circuit board. The ambient temperature measurement module may receive the ambient temperature via 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 the second heat conducting end. In this way, the ambient temperature collected by the first heat conducting end is transmitted to the second heat conducting end and then received by the ambient temperature measurement module. The heat conduction path is shorter, which is conducive to improving the measurement accuracy of the ambient temperature.

[0013] In order to improve the reliability of the connection between the ambient temperature measurement module and the button, in one possible implementation of the present application, the ambient temperature measurement module may further include a cover plate. The cover plate is mounted on an assembly structure formed by connecting the first temperature sensor, the first circuit board, and the end of the button rod facing away from the button cap. In addition, the cover plate may have an inner contour that matches the outer contour of the above-mentioned assembly structure, thereby providing the cover plate with better fixing and protection capabilities, and the cover plate occupies less space within the housing of the wearable device.

[0014] In addition to using the button as a heat conductor in the present application, in another possible implementation of the present application, the heat conducting structure can also be provided as an independent structure. In a specific configuration, the heat conducting structure can also include a connecting portion for connecting the first heat conducting end and the second heat conducting end. It is understood that the heat conducting structure can be an integrally molded structure to improve its structural stability.

[0015] The connecting wall of the housing may also be provided with a key slot for mounting a key, and the first heat-conducting end of the heat-conducting structure may extend into the key slot to collect ambient temperature. In addition, there is a clearance space between the key and the first heat-conducting end to avoid interference between the two when performing their respective functions.

[0016] In a possible implementation of the present application, a bracket may be further provided on one side of the connecting wall of the housing located within the accommodating space, and the bracket may support the connecting wall, thereby improving the structural stability of the entire housing.

[0017] The connection portion of the thermally conductive structure can be embedded in the bracket, which can reduce the space occupied by the thermally conductive structure. In addition, by embedding the thermally conductive structure in the bracket, the bracket can also support the thermally conductive structure, which reduces the need for structural strength of the thermally conductive structure. This allows the thermally conductive structure to be made of materials with higher thermal conductivity, thereby improving the accuracy of its temperature detection.

[0018] In another possible implementation of the present application, the connecting wall can be used as a heat-conducting structure. The side of the connecting wall located outside the storage space can serve as the first heat-conducting end, and the side of the connecting wall located inside the storage space can serve as the second heat-conducting end. This can effectively simplify the structure of the wearable device and facilitate the acquisition of ambient temperature.

[0019] In a possible embodiment of the present application, foam may be mounted on a side of the ambient temperature measurement module that is away from the second heat conducting end, so as to protect the ambient temperature measurement module.

[0020] The skin-tight temperature measurement module may include a second temperature sensor and a second circuit board assembly, wherein the second circuit board assembly includes a second circuit board, and the second temperature sensor may be disposed on the second circuit board, and the second circuit board and the second circuit board are electrically connected.

[0021] The wearable device may further include a photoplethysmography lens disposed on the wearable device. Furthermore, the photoplethysmography lens may be a portion of the first surface of the wearable device housing. In this manner, one of the second temperature sensor and the second circuit board may be attached to the photoplethysmography lens to collect human skin temperature.

[0022] In a possible implementation of the present application, the thermal conductivity of the photoplethysmograph lens may 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-tight temperature measurement module.

[0023] The PPG lens can be divided into a translucent area and a non-translucent area. This allows light emitted by the PPG module's light source to pass through the translucent area and enter the human body, or light reflected by the human body to pass through the translucent area and be received by the PPG module's photodetector. Furthermore, by adjusting the position of the light source or the direction of light emitted by the light source, the lens can ensure that as much light as possible is transmitted through the translucent area, thereby reducing energy loss and improving the detection accuracy of the PPG module.

[0024] The skin-mounted temperature sensor can be provided with a non-light-transmitting area of ​​the lens of the photoplethysmograph to avoid blocking the light emitted or reflected from the light source.

[0025] In a possible implementation of the present application, the skin-tight temperature measurement module may further include a temperature measurement structure, which includes a heat conductor, the heat conductor including a fixed portion and a contact portion connected to each other, the fixed portion being located in the accommodating space, and the fixed portion being fixedly connected to the outer shell, thereby achieving a fixed connection between the heat conductor and the outer shell. In addition, one of the second temperature sensor and the second circuit board is fixed to a side of the fixed portion facing away from the contact portion. The first shell is provided with a mounting hole, which passes through the first surface, and at least a portion of the contact portion extends from the mounting hole to the outside of the outer shell. In this way, direct contact between the contact portion and the human skin can be achieved, which is conducive to improving the measurement accuracy of the skin temperature.

[0026] A second sealing member may be provided on the contact portion, and the second sealing member may be interference-fitted with the contact portion and the hole wall of the mounting hole, thereby achieving a waterproof sealing effect.

[0027] In one possible implementation of the present application, the skin-attached temperature measurement module may include at least two temperature measurement modules, which are spaced apart. By providing at least two temperature measurement modules, multi-point skin temperature measurement can be achieved. This allows for improved skin temperature measurement accuracy by the attached temperature measurement module through mutual calibration between the temperature measurement modules, thereby improving the wearable device's accuracy in measuring human body temperature.

[0065] In order to make the purpose, technical solutions and advantages of this application clearer, this application will be further described in detail below with reference to the accompanying drawings.

[0066] To facilitate understanding of the wearable device provided in the embodiments of the present application, the following first describes its application scenarios. The wearable device can be, but is not limited to, a portable electronic device such as a smartwatch or smart bracelet. Taking a smartwatch as an example, it can be worn on the user's wrist to detect the user's body temperature and other physical signs at any time, so as to achieve predictive knowledge of the user's physical condition, thereby effectively reducing the risk of dangerous diseases.

[0067] Currently, the temperature measurement modules of smartwatches with body temperature measurement functions can be divided into two categories: one is non-contact temperature measurement modules, represented by infrared temperature measurement. These temperature measurement modules are relatively complex and costly, and require more space for installation, making them difficult to implement. Furthermore, infrared-based non-contact temperature measurement modules often require space within the smartwatch casing to transmit infrared light. This can detract from the smartwatch's aesthetics.

[0068] Another type of temperature measurement module typically involves creating a hole in the housing to place a temperature sensor inside; alternatively, a simple thermally conductive column connected to the temperature sensor extends from the hole to achieve temperature measurement. This approach can lead to significant measurement errors due to the varying thermal conductivity of the housing and significant environmental influences. Furthermore, creating a hole in the housing and placing the temperature sensor inside the hole makes waterproofing a wearable product difficult. If the temperature sensor is enclosed in a sealant, measurement errors can be significant.

[0069] As can be seen from the above description, most current smartwatches with temperature measurement modules measure the temperature of the human wrist skin. However, wrist skin temperature is not the same as body temperature and is significantly affected by ambient temperature. Therefore, wrist skin temperature cannot accurately reflect human body temperature.

[0070] Based on this, the present application provides a wearable device, which can obtain relatively accurate human body temperature measurement results by simultaneously setting an environmental temperature measurement module and a skin-tight temperature measurement module to input the obtained environmental temperature data and skin temperature data into the algorithm.

[0071] In order to make the purpose, technical solutions and advantages of this application clearer, this application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0072] The terms used in the following embodiments are only for the purpose of describing specific embodiments and are not intended to be limiting of the present application. As used in the specification of the present application and the appended claims, the singular expressions "a", "an", "above", "the" and "this" are intended to also include expressions such as "one or more", unless there is a clear contrary indication in the context. It should also be understood that in the following embodiments of the present application, "at least one", "one or more" refer to one, two or more. The term "and / or" is used to describe the association relationship of associated objects, indicating that three relationships may exist; for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and subsequent associated objects are in an "or" relationship.

[0073] References to "one embodiment" or "some embodiments" in this specification mean that a particular feature, structure, or characteristic described in conjunction with that embodiment is included in one or more embodiments of the present application. Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in yet other embodiments" appearing in various places in 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 "including," "comprising," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0074] In this application, the algorithm for calculating human body temperature plays a vital role in the wearable device's temperature measurement function. When the wearable device provided in this application is in the development stage, the algorithm can be trained based on the ambient temperature data collected by the ambient temperature measurement module for the same object at the same time, the skin data collected by the skin-tight temperature measurement module for the same object at the same time, and accurate human body temperature data, taking into account individual differences in the collected objects, such as age and gender, to finally realize the algorithm's function.

[0075] Reference Figure 1 , Figure 1 The calculation flow chart of the human body temperature obtained by the algorithm is shown. 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-tight temperature measurement module are the inputs of the algorithm, while the human body temperature data T3 is the output of the algorithm.

[0076] In addition, refer to Figure 2 , Figure 2 The human body temperature curve obtained by using the above algorithm in one embodiment of the present application is shown. Figure 2In the figure, the curve with prisms represents the ambient temperature data T1 measured by the ambient temperature measurement module, the curve with squares represents the skin temperature data T2 measured by the skin-tight temperature measurement module, and the curve with triangles represents the human body temperature data T3 obtained by the algorithm. Figure 2 It can be seen that, by using the algorithm of the present application, the curve of the human body temperature data T3 obtained by calculating the corresponding multiple sets of ambient temperature data T1 and skin temperature data T2 is relatively flat, which proves the practicality and reliability of the algorithm.

[0077] After a preliminary understanding of the principle of human body temperature measurement of the wearable device provided in this application, the specific setting method of the ambient temperature measurement module and the skin-mounted temperature measurement module in the wearable device is introduced in conjunction with the accompanying drawings.

[0078] Reference Figure 3 , Figure 3 This is a schematic diagram of the structure of a wearable device provided by an embodiment of the present application. In this application, a smart watch is taken as an example to introduce the wearable device that can measure body temperature.

[0079] exist Figure 3 In the illustrated embodiment, the wearable device may include a housing 1 having a first shell 101 and a second shell 102. The first shell 101 and the second shell 102 are engaged with each other to form a receiving space 103 of the housing 1 for accommodating a functional module of the wearable device between the first shell 101 and the second shell 102.

[0080] In addition, the first shell 101 may include a first surface 1011. In the present application, the first surface 1011 may be the surface that contacts the human body when the wearable device is worn. The second shell 102 may include a second surface (not shown in the figure), which is arranged opposite to the first surface 1011. In a possible embodiment of the present application, the second surface may be the surface of a display screen, which may be used to display the results obtained by measuring the functional modules of the wearable device. It is understandable that in Figure 3 In order to show the accommodating space 103 of the housing 1, the display screen is omitted.

[0081] A connecting wall 1021 is provided between the first surface 1011 and the second surface, and is used to connect the first surface 1011 and the second surface. Furthermore, the connecting wall 1021 can be provided on either 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.

[0082] You can continue to refer to Figure 3, the wearable device may further include a button 2. In one embodiment of the present application, the button 2 may be provided on the exterior surface of the wearable device. For example, it may be provided on the second surface or the connecting wall 1021. Figure 3 In the embodiment shown, the button 2 is arranged on the connecting wall 1021, which is conducive to achieving a narrow-frame design for the display screen of the wearable device.

[0083] In this application, when setting button 2, please refer to Figure 4 , Figure 4 The schematic diagram of the structure of a key 2 of an embodiment of the present application is shown. The key 2 may include a key cap 201 and a key rod 202 connected to each other. The key cap 201 may be, but is not limited to, circular, oval or rectangular. Figure 3 and Figure 4 At least a portion of the key cap 201 extends from the connecting wall 1021 to the outside of the housing 1 and contacts the external environment, thereby facilitating operation of the key 2. The key stem 202 extends into the interior of the accommodating space 103 of the housing 1 and can be used to connect to a functional module within the accommodating space 103.

[0084] The button 2 of the wearable device provided in this application can be set to Figure 3 The push button in the embodiment shown in the figure can control the implementation 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, the button 2 can also be set as a rotary button to control the implementation of the corresponding function of the functional module by rotating the button 2. It is understandable that the above is only some exemplary descriptions of the setting form of the button 2 of the present application. In other embodiments of the present application, the button 2 can also adopt other possible settings, such as including the performance of both a press key and a rotary key, which are not introduced one by one here. In addition, a clearance space is reserved in the accommodating space 103 for linear reciprocating or rotational movements of the button. It should be understood that in the present application, there is no necessary connection between the shape of the button cap 201 and the specific setting form of the button 2. For example, a button 2 with a circular button cap 201 can be both a press key and a rotary key; a button 2 with an oval button cap 201 can be both a press key and a rotary key. For the sake of distinction, in the following embodiments of the present application, the button 2 that can be used to control the functional module is recorded as a function button 2a.

[0085] From the above introduction to the human body temperature measurement principle of the wearable device, it can be seen that the wearable device provided in this application can include an ambient temperature measurement module. In one possible embodiment, the ambient temperature measurement module can be integrated with the function button 2a of the wearable device.

[0086] In a specific implementation, since the key cap 201 can come into contact with the external environment, in this embodiment, the key cap 201 can be made of a material with a high thermal conductivity coefficient, so that the key 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 a possible embodiment of the present application, the material of the key 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 the present application, the key stem 202 can also be made of a material with a high thermal conductivity coefficient, which 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, so that heat can be transferred between the key cap 201 and the key stem 202. It will be understood that in the present application, the materials of the key cap 201 and the key stem 202 can be the same or different, as long as efficient heat transfer between the two can be achieved.

[0087] Reference Figure 6a , Figure 6a The cross-sectional structure diagram of the function key 2a of an embodiment of the present application is shown. In this embodiment, the structure of the function key 2a can be the same as that of the above Figure 4 The structure of the key 2 shown in FIG is the same as that of the key 2 shown in FIG. Figure 6a Shown Figure 4 The cross-sectional structure at AA in the middle. The function key 2a can be an integrally molded structure, which can be formed by, but is not limited to, multi-shot injection molding, multi-shot casting, three-dimensional additive manufacturing, or powder metallurgy. Alternatively, the function key 2a can be an assembled structure, wherein the key cap 201 and the key stem 202 can be fixedly connected by, but is not limited to, welding, bonding, riveting, clamping, or threaded connection.

[0088] In some embodiments of the present application, the button cap 201 and / or the button stem 202 may also adopt an inner and outer layer structure design. Figure 6a In the embodiment shown, both the key cap 201 and the key stem 202 are designed as inner and outer layer structures, and the inner and outer layer structures can be divided into: outer layer fully wrapped, outer layer half wrapped, outer layer surface patch and other forms. Figure 6a In the illustrated embodiment, the keycap 201 adopts a semi-enclosed design, while the key stem 202 adopts a fully enclosed design. The inner portion 2032a of the keycap 201 has at least two surfaces in contact with the outer portion 2031a, and at least one surface is located outside the outer portion 2031a. The outer portion 2031b of the key stem 202 forms a closed space, with the inner portion 2032b completely enclosed within the closed space. In the fully enclosed design, no surface of the inner portion 2032 comes into contact with the outside world or external components.

[0089] In some other embodiments, the key cap 201 and the key stem 202 may also be designed in a semi-enclosed or fully-enclosed manner, and their specific configuration is similar to that of the above embodiment and will not be described in detail here.

[0090] Reference Figure 6b , Figure 6b The cross-sectional structure diagram of a key with a key cap 201 designed in the form of a surface mount is shown. In this embodiment, only one surface of the inner layer 2032 of the key cap 201 contacts the outer layer 2031, while the remaining surfaces are located outside the outer layer 2031. In addition, it is worth mentioning that Figure 6b In the illustrated embodiment, the key stem 202 is an integrally formed structure, which can be formed using methods such as multi-shot injection molding, multi-shot casting, 3D additive manufacturing, or powder metallurgy. Furthermore, the key stem 202 and key cap 201 can be integrally formed, which can be formed using methods such as, but not limited to, injection molding, multi-shot casting, 3D additive manufacturing, or powder metallurgy. Alternatively, the key stem 202 and key cap 201 can be assembled using methods such as, but not limited to, welding, bonding, clamping, or threaded connection.

[0091] As can be seen from the above embodiments, the function key 2a provided herein can exhibit high thermal conductivity. When the key cap 201 and / or key stem 202 utilize an inner and outer layer structure, both the inner layer 2032 and the outer layer 2031 can exhibit high thermal conductivity. In a specific implementation, for example, the outer layer 2031 can be made of a metal with a high thermal conductivity coefficient, such as aluminum alloy or stainless steel, or a material with high thermal conductivity, such as ceramic, sapphire, or plastic. The thermal conductivity coefficient of the outer layer 2031 made of such materials is approximately 35-200 W / (m·K). This allows the outer layer 2031 to have high thermal conductivity while maintaining reliable structural stability, thereby meeting the structural strength requirements of the entire function key 2a. Furthermore, the surface of the outer layer 2031 can be treated with surface treatments, including but not limited to polishing, painting, brushing, or matte finishes, to enhance the aesthetic appearance of the function key 2a.

[0092] Since at least a portion of the inner layer 2032 can be covered by the outer layer 2031, its structural strength can have a smaller impact on the structural stability of the entire function key 2a. Therefore, in the present 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 a copper alloy is approximately 200-380 W / (m·K), its thermal conductivity efficiency is high, which is 5-10 times that of ordinary metal materials. Therefore, the thermal conductivity of the inner layer 2032 made of this material can reach 200-380 W / (m·K). In the present application, by configuring the key cap 201 and / or the key stem 202 of the function key 2a as an inner and outer layer structure, the thermal conductivity efficiency of the entire key can be effectively improved.

[0093] In one possible embodiment of the present application, the function key 2a can be formed using, but is not limited to, two-shot injection molding, two-shot casting, three-dimensional additive manufacturing, or powder metallurgy. These molding methods enable layered manufacturing of the keycap 201 and / or key stem 202, and the joining of the inner layer 2032 and outer layer 2031. Furthermore, subsequent CNC machining and surface treatment processes can be used to ensure the appearance, mechanical properties, and high thermal conductivity of the function key 2a.

[0094] In the above embodiments, the specific design of the function key 2a is described using the assembled structure. In other embodiments of the present application, the function key 2a can also be an integrally formed structure. In this embodiment, if the key cap 201 and the key stem 202 adopt an inner and outer layer structure, the inner layer 2032 of the key cap 201 and the outer layer 2031 of the key stem 202 can be, but are not limited to, integrally formed. This can effectively simplify the key structure and processing technology, thereby improving key processing efficiency.

[0095] Reference Figure 7 , Figure 7 The following is a schematic diagram showing the decomposition structure of a wearable device according to another embodiment of the present invention. In order to facilitate the description of the connection and position relationship between the ambient temperature measurement module and the function button 2a, Figure 7 The housing of the wearable device is omitted. In this embodiment of the present application, the ambient temperature measurement module is arranged as follows Figure 3The ambient temperature measurement module is shown within the housing space 103 of the wearable device's housing 1. This allows the housing 1 to protect the ambient temperature measurement module, improving the wearable device's structural reliability. Furthermore, the ambient temperature measurement module may include a first temperature sensor 301 and a first circuit board assembly 302. The first temperature sensor 301 can be fixed to the end of the key stem 202 facing away from the key cap 201, so that the end of the key stem 202 facing away from the key cap 201 serves as a second heat-conducting end. It is understood that the portion of the key stem 202 used to connect the first heat-conducting end and the second heat-conducting end can serve as a connecting portion. In this way, the ambient temperature collected by the key cap 201, which serves as the first heat-conducting end, can be transferred to the second heat-conducting end through the connecting portion of the key stem 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 key stem 202, the first temperature sensor 301 can be bonded to the end of the key stem 202 using thermally conductive adhesive 303.

[0096] 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 stem 202 facing away from the button cap 201 (the second heat-conducting end). This surface provides a flat mounting surface for the first temperature sensor 301 to be mounted on the button stem 202, thereby facilitating the installation and securing of the first temperature sensor 301. Furthermore, the area of ​​the mounting surface 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 sensed by the first temperature sensor 301.

[0097] You can continue to refer to Figure 7 The first circuit board assembly 302 may include a first circuit board 3021. The first circuit board 3021 may be, for example, a flexible printed circuit (FPC), which facilitates the layout of the first circuit board 3021 within the housing 1 of the wearable device. It is understood that in some possible embodiments of the present application, the first circuit board 3021 may also be a printed circuit board (PCB), which may be applied to wearable devices with ample accommodation space 103 of the housing 1.

[0098] 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. Figure 7In the illustrated embodiment, the first circuit board 3021 can be disposed on the side of the first temperature sensor 301 facing away from the button stem 202. However, in other embodiments of the present application, the first circuit board 3021 can also be disposed between the first temperature sensor 301 and the button stem 202. In this case, the first circuit board 3021 can be fixed to the button stem 202 via thermally conductive adhesive 303. In the present application, by disposing the first temperature sensor 301 and the first circuit board 3021 at the end of the button stem 202 facing away from the button cap 201, the housing 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 in collecting ambient temperature.

[0099] The above embodiment is merely an illustrative description of the relative positional relationship between the first circuit board 3021, the first temperature sensor 301, and the key rod 202. Furthermore, those skilled in the art may design a suitable layout based on the type of first temperature sensor 301 selected and the connection process between the first temperature sensor 301 and the first circuit board 3021, and all such arrangements should be understood to fall within the scope of protection of this application.

[0100] In addition, a key rubber gasket 3022 and a key spring 3023 may be provided on the first circuit board 3021 but are not limited to being provided thereon. The key rubber gasket 3022 may be used to act as a buffer, and the key spring 3023 may be used as a switch for the function key 2a.

[0101] In a possible embodiment of the present application, in order to ensure stable connection between the first circuit board 3021, the first temperature sensor 301 and the key rod 202, the ambient temperature measurement module may further include a cover plate 304. Figure 7 As can be seen, the cover plate 304 can lock and secure the assembled first circuit board 3021, first temperature sensor 301, and key rod 202. In a specific implementation, the cover plate 304 can have an inner contour that matches the outer contour of the assembly structure formed by connecting the first circuit board 3021, first temperature sensor 301, and the end of the key rod 202 facing away from the key cap 201. In this way, the cover plate 304 can be placed within the assembly structure, thereby providing the cover plate 304 with better fixing and protection capabilities, and the cover plate 304 can be used in various situations. Figure 3 The illustrated wearable device occupies a smaller space within the receiving space 103 of the housing 1. It is worth mentioning that in the embodiment of the present application, the cover plate 304 may be, but is not limited to, an injection molded part obtained through an injection molding process, or a metal part obtained through a metal processing process (such as stamping). The processing process and material of the cover plate 304 are not limited in this application.

[0102] In addition, you can continue to refer to Figure 7 In a possible embodiment of the present 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 rod 202 through the adhesive material 305, thereby effectively improving the connection reliability of the structure assembled by the cover plate 304 and the first circuit board 3021, the first temperature sensor 301 and the button rod 202.

[0103] Reference Figure 8 , Figure 8 for Figure 7 The function button 2a and the ambient temperature measurement module shown in FIG are a partial structural diagram after being installed in the housing 1. Figure 8 3 shows the relative positional relationship between the key rubber gasket 3022 and the key spring 3023 and the function key, wherein the key rubber gasket 3022 can be located between the function key and the key spring 3023 to play a buffering role.

[0104] Continue to refer to Figure 8 In some embodiments of the present application, a waterproof groove 2022 may be provided on the key rod 202 of the function key 2a. The waterproof groove 2022 may be an annular groove provided around the key rod 202. In addition, a first sealing member 205 may be installed in the waterproof groove 2022. The first sealing member 205 may be, but is not limited to, Figure 4 . It is understood that the first sealing member 205 may be interference-fitted with the key stem 202 and the sidewall of the housing 1, or a structural component within the housing 1's accommodation space, to provide a waterproof seal. The interference fit between the first sealing member 205 and the key stem 202 and the sidewall of the housing 1, or a structural component within the housing 1, may be, but is not limited to, interference fit, abutment, or embedding.

[0105] It is worth mentioning that in Figure 7 and Figure 8 In the illustrated embodiment, the function key 2a can be configured as a push key. The key can further include an elastic member 204, which can be disposed on the side of the keycap 201 facing the key stem 202. The elastic member 204 can, but is not limited to, elastically abut against the housing 1 or a structural member disposed within the accommodation space. Thus, when the function key 2a is pressed, the elastic member 204 accumulates elastic force, and when the function key 2a is released, the elastic member 204 releases the elastic force, thereby pushing the function key 2a back into position. Furthermore, the elastic member 204 can, but is not limited to, be a spring, and the spring coefficient and number of the springs can be designed based on specific elasticity requirements.

[0106] From the above introduction to the shell 1 of the wearable device, it can be known that in this application, the first surface 1011 of the first shell 101 of the shell 1 can be used as the surface of the wearable device in contact with the human body, and the skin-type temperature measurement module can be used to measure the skin temperature of the human body. The skin-type temperature measurement module can be set in the first shell 101.

[0107] Reference Figure 9 , Figure 9 A schematic structural diagram of a first housing 101 according to an embodiment of the present application is provided. In this embodiment, the wearable device is provided with a photoplethysmograph (PPG) module, which includes a PPG lens 5 disposed in the first housing 101. The specific shape of the PPG lens 5 is not limited in this application; for example, the PPG lens 5 can be circular, rectangular, or any other regular or irregular shape.

[0108] In the embodiment of the present application, the PPG lens 5 is inlaid or bonded to the first shell 101, and the PPG lens 5 can be used as a part of the first surface 1011 to contact the skin of the wearing part. Since the material of the PPG lens 5 can usually be sapphire, sapphire has good thermal conductivity, and its thermal conductivity coefficient is about 35-55W / (m·K). Therefore, in this embodiment of the present application, the PPG lens 5 can be used for collecting skin temperature. In addition, in the present application, the specific setting position of the PPG lens 5 on the first shell 101 is not limited. For example, it can be set at the center of the first shell 101 to effectively increase the contact area between the PPG lens 5 and the wearing part, thereby improving its accuracy in collecting skin temperature.

[0109] In a possible embodiment of the present application, the skin-tight temperature measurement module 4 can be set on the PPG lens 5, so that the human skin temperature information can be efficiently transmitted to the skin-tight temperature measurement module 4 through the PPG lens 5, without adding other heat-conducting structures 6 such as heat-conducting columns, thereby effectively simplifying the structure of the wearable device.

[0110] Reference Figure 10 , Figure 10 for Figure 9 An enlarged view of the partial structure at point B in the figure. In this embodiment, the skin-tight 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 mounted on the PPG lens 5 so that the skin temperature collected by the PPG lens 5 can be efficiently transmitted 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 to the PPG lens 5 using thermally conductive adhesive 303.

[0111] You can continue to refer to Figure 10 In some other embodiments of the present 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 by the light source of the PPG module to pass through the light-transmitting area 501 and enter the human body, or allows light reflected by the human body to pass through the light-transmitting area 501 and be received by the photodetector of the PPG module. In addition, by adjusting the position of the light source or the direction of the light emitted by the light source, as much light as possible can be transmitted through the light-transmitting area 501, thereby reducing energy loss and improving the detection accuracy of the PPG module.

[0112] It can be understood that in the embodiment of the present application, the second temperature sensor 401 can be set in the non-light-transmitting area 502 of the PPG lens 5, so as to avoid the second temperature sensor 401 blocking the light emitted or reflected by the light source.

[0113] When specifically setting up the second circuit board assembly 402, you can continue to refer to Figure 10 The second circuit board assembly 402 may include a second circuit board 4021. The second circuit board 4021 may be a flexible printed circuit (FPC). This makes it easier for the second circuit board 4021 to be mounted on a Figure 3 It is understood that in some possible embodiments of the present application, the second circuit board 4021 may also be a printed circuit board (PCB), which can be applied to wearable devices with ample accommodation space 103 of the housing 1.

[0114] Reference Figure 11 , Figure 11 Shown Figure 10 In this embodiment of the present application, the second circuit board 4021 is electrically connected to the second temperature sensor 401. 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 the present application, the second circuit board 4021 can also be disposed between the second temperature sensor 401 and the PPG lens 5. In this case, the second circuit board 4021 can be fixed to the PPG lens 5 via thermally conductive adhesive 303. The above embodiment is merely an illustrative illustration 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 may design a reasonable layout based on the type of second temperature sensor 401 selected and the connection process between the second temperature sensor 401 and the second circuit board 4021, and all such arrangements should be understood to fall within the scope of protection of the present application.

[0115] It is worth mentioning that a key rubber gasket may also be provided on the second circuit board 4021 but is not limited to being provided thereon to provide a buffer for the second circuit board 4021 .

[0116] In addition, in some possible embodiments, the second circuit board 4021 may be the same circuit board as the first circuit board 3021 of the above embodiment, so as to effectively simplify the structure of the wearable device and allow the accommodating space 103 of the shell 1 to have extra space for installing other functional modules, thereby realizing a functionally diversified design of the wearable device.

[0117] It is understandable that the PPG lens and skin-mounted temperature measurement module 4 provided in the above embodiment can not only be arranged on the first housing 101 but also be provided on the skin-mounted temperature measurement module 4. Figure 9 In addition to the wearable device of the shape shown, it can also be set in, but not limited to, Figure 12 In addition, refer to the wearable device of the shape shown. Figure 13 , Figure 13 Shown Figure 12 The structure of the first shell 101 of the wearable device shown in FIG. 1 is shown in FIG. 2 . In this embodiment, the specific configuration of the PPG lens and the skin-mounted temperature measurement module 4 can be referred to. Figure 9 The embodiments shown are not described in detail here.

[0118] Reference Figure 14 , Figure 14 The configuration of the skin-mounted temperature measurement module 4 in another possible embodiment of the present application is shown. In this embodiment, the configuration of the skin-mounted temperature measurement module 4 is independent of the design of the PPG lens 5. In specific implementation, the skin-mounted temperature measurement module 4 may include one temperature measurement structure 403; or may include at least two temperature measurement structures 403, such as Figure 14As shown, the at least two temperature measurement structures 403 can be, but are not limited to, disposed around the periphery of the PPG lens 5 and spaced apart. Their arrangement can be, but is not limited to, symmetrical or in a matrix. This allows for algorithm optimization through multi-point skin temperature measurement, thereby improving the accuracy of human body temperature measurement.

[0119] Reference Figure 15 , Figure 15 This is a structural schematic diagram of the temperature measuring structure 403 of a possible embodiment of the present application. The temperature measuring structure 403 may include a heat conductor 4031, and the heat conductor 4031 includes a fixing portion 40311 and a contact portion 40312. The fixing portion 40311 and the contact portion 40312 may be an integrally formed structure; or the fixing portion 40311 and the contact portion 40312 are independent structures, and the two may be connected by, but not limited to, double-shot injection molding, double-shot injection molding, multi-shot casting, three-dimensional additive manufacturing or powder metallurgy. Or they may be assembled by bonding, welding or threaded connection. In addition, the fixing portion 40311 and the contact portion 40312 may be made of a single material, or be set as an inner and outer layer structure. When it adopts an inner and outer layer structure design, its specific setting method and material selection can refer to the introduction of the function keys adopting the inner and outer layer structure design in the above embodiment, and will not be repeated here.

[0120] In this embodiment of the present application, the fixing portion 40311 can be used to Figure 14 The housing 1 of the wearable device shown is fixedly connected, thereby achieving a fixed connection between the heat conducting member 4031 and the housing 1. It can be understood that when the heat conducting member 4031 is installed on the housing 1, the fixing portion 40311 can be located in the receiving space 103 of the housing 1 (see Figure 3 ), and the fixing portion 40311 is fixedly connected to the housing 1. Exemplarily, the fixing portion 40311 can be fixed to one side of the first surface 1011 located in the accommodating space 103.

[0121] In addition, you can also refer to Figure 14 and Figure 15 The first shell 101 may be provided with a mounting hole 1012, which passes through the first surface 1011. At least a portion of the contact portion 40312 extends from the mounting hole 1012 to the outside of the shell 1 for contacting the skin of the wearing part. Figure 15A second sealing member 40313 may also be provided on the contact portion 40312. This second sealing member 40313 may be, for example, an annular rubber ring. This second sealing member 40313 may be assembled by interference fit between the contact portion 40312 and the wall of the mounting hole 1012, thereby providing a waterproof seal. It is understood that in this embodiment of the present application, the portion of the first housing 101 where the heat conductor 4031 is disposed may be made of a material with a low thermal conductivity, such as plastic, to minimize its impact on the temperature collection process of the heat conductor 4031.

[0122] The temperature measurement structure 403 may also include a second circuit board 4021, which is fixed to the side of the fixing portion 40311 facing away from the contact portion 40312 via thermally conductive adhesive 303. In addition, a second temperature sensor 401 is provided on the second circuit board 4021. The second temperature sensor 401 may be fixed to the second circuit board 4021 via, but is not limited to, thermally conductive adhesive 303. In this way, the skin temperature collected via the contact portion 40312 is transmitted to the second temperature sensor 401 via the fixing portion 40311 and the second circuit board 4021. Figure 15 In some possible embodiments of the present application, the second circuit board 4021 can also be connected to the contact portion 40312 and the fixing portion 40311 respectively through the thermal conductive adhesive 303, so that the skin temperature collected through the contact portion 40312 can be directly transferred to the second circuit board 4021, which is conducive to improving the accuracy of temperature measurement.

[0123] In another possible embodiment of the present application, the second temperature sensor 401 may be fixed to the heat conductor 4031 via thermally conductive adhesive 303, and the second circuit board 4021 may be fixed to the second temperature sensor 401 via thermally conductive adhesive 303. Those skilled in the art may reasonably arrange the second temperature sensor 401 based on the type of the second temperature sensor 401 selected 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 scope of protection of the present application.

[0124] Continue to refer to Figure 15 A stopper 403111 may be further provided on the side of the fixing portion 40311 of the heat conducting member 4031 facing away from the contact portion 40312. Two stoppers 403111 may be provided opposite each other, and the second temperature sensor 401, the second circuit board 4021, and other structures connected to the heat conducting member 4031 may be provided between the two stoppers 403111, thereby limiting the position of the second temperature sensor 401, the second circuit board 4021, and other structures on the fixing portion 40311.

[0125] As can be seen from the above description of the temperature measurement structure 403, in some embodiments of the present application, each temperature measurement structure 403 can be provided with a corresponding second circuit board 4021 and a second temperature sensor 401. In other embodiments, each temperature measurement structure 403 can be provided with a corresponding second temperature sensor 401, and at least two temperature measurement structures 403 can share a second circuit board 4021. This can effectively simplify the structure of the skin-mounted measurement module. By using multiple temperature measurement structures 403 to simultaneously measure skin temperature, the accuracy of skin temperature measurement can be effectively improved, thereby improving the accuracy of human body temperature measurement.

[0126] It is understandable that in Figure 14 and Figure 15 In the embodiment shown, the contact portion 40312 of the temperature measuring structure 403 is designed as a rectangular outline. In other embodiments of the present application, the contact portion 40312 can also be designed as follows Figure 16 The multi-segment arc profile design shown in Figure 17 The circular contour design shown in , of course, can also adopt contour designs of other shapes such as petal shape, which are not listed here one by one.

[0127] In the above embodiment of the present application, the button for setting the ambient temperature measurement module can be pressed or rotated to control the functional modules of the wearable device. In some other possible embodiments of the present application, the button for connecting to the ambient temperature measurement module can be designed separately. In this embodiment, in addition to being used to collect the ambient temperature, the button is not connected to any other functional module, and pressing or rotating the button cannot be used to implement any function. In this application, such a button can be referred to as a "fake button."

[0128] In order to improve the appearance of the wearable device and avoid interference with the operation of the function keys, the length of the key cap 201 of the dummy key 2b extending outside the housing 1 can be reduced. Figure 18 , Figure 18 This embodiment illustrates the placement of a dummy button 2b in a wearable device. In this embodiment, the surface of the button cap 201 of the dummy button 2b can be designed to conform to the surface contour of the connecting wall 1012 of the housing 1, thereby improving the continuity of the wearable device's surface contour and enhancing its appearance.

[0129] Reference Figure 19 , Figure 19 for Figure 18The exploded structural diagram of the wearable device is shown in FIG. In this embodiment, the elastic element is not required on the keycap 201, thereby simplifying the structure of the wearable device. The structure and material selection of the keycap 201 and key stem 202 of the dummy key 2b can be similar to those of the functional keys in the above-mentioned embodiments and will not be further described here.

[0130] You can continue to refer to Figure 19 , a through hole 1022 may be provided on the connecting wall 1012, and the key rod 202 of the dummy key 2b may pass through the through hole 1022 and extend into the accommodation space 103. In some embodiments of the present application, the length of the key rod 202 extending into the accommodation space 103 may be shortened as much as possible. Figure 20 As shown, Figure 20 for Figure 18 In this embodiment, the key cap 201 and / or the key rod 202 may be miniaturized, which can reduce the occupation of the accommodating space 103 by the dummy key 2b.

[0131] It is understandable that Figures 18 to 20 The ambient temperature measurement module, the skin-tight temperature measurement module, and the method for realizing human body temperature measurement in the illustrated embodiment can be configured with reference to any of the above embodiments and will not be described in detail here.

[0132] Through the above embodiments, the specific configuration of the ambient temperature measurement module in the wearable device can be understood as follows: as long as the ambient temperature can be transferred to the ambient temperature measurement module through a heat-conducting structure, the ambient temperature measurement module can obtain the ambient temperature. Based on this, in addition to being a button (function button or dummy button) in the above embodiments, in other embodiments of the present application, the heat-conducting structure can also be hidden in the housing to avoid affecting the appearance of the wearable device.

[0133] When implementing it, refer to Figure 21 , Figure 21 The schematic diagram of the heat-conducting structure 6 of a possible embodiment of the present 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 measured along the Figure 21 The arrow shown in FIG. 6 is directed from the first heat conducting end 601 to the second heat conducting end 602 through the connecting portion 603 .

[0134] In this embodiment of the present application, the heat-conducting structure 6 can be an integrally formed structure or can adopt an inner and outer layer structure design. Its specific setting method and material selection can refer to the function keys introduced in the above embodiment and will not be repeated here.

[0135] When the heat conducting structure 6 is arranged on the housing 1, reference can be made to Figure 22a , Figure 22a This is a schematic diagram of the structure of a wearable device according to another embodiment of the present application. The first heat-conducting end 601 of the heat-conducting structure 6 can extend into the connecting wall 1012 of the housing 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 by the wearable device.

[0136] You can continue to refer to Figure 22a ,exist Figure 22a In the illustrated embodiment, the first heat-conducting end 601 extends into the key slot 104 of the housing 1, which is used to mount a key (a function key or a dummy key). It will be appreciated that, in this embodiment, a clearance space can be provided within the key slot 104 to allow the first heat-conducting end 601 to escape, thereby preventing interference between the key and the first heat-conducting end 601, allowing the key and the first heat-conducting end 601 to function independently. Furthermore, by locating the first heat-conducting end 601 within the key slot 104, the structure and manufacturing process of the housing 1 can be effectively simplified.

[0137] Since the first heat conducting end 601 of the heat conducting structure 6 can extend into the key slot 104, the second heat conducting end 602 is located in the accommodation space 103. Figure 21 and Figure 22a In a possible embodiment of the present application, a hollow area 6031 may be provided on the connection portion 603 of the heat conducting structure 6. The hollow area 6031 may be used to avoid the key rod of the key, thereby avoiding interference with the key operation. Figure 21 and Figure 22a In the embodiment shown, two first heat-conducting ends 601 can also be set, and the two first heat-conducting ends 601 are respectively arranged 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.

[0138] Reference Figure 22b , Figure 22bThe structure of the wearable device at another angle is shown. The second heat-conducting end 602 of the heat-conducting structure 6 can extend into the interior of the accommodating space 103 of the housing 1, and the ambient temperature measurement module can be fixed to the second heat-conducting end 602, so that the ambient temperature collected by the first heat-conducting end 601 can be transmitted to the ambient temperature measurement module through the connecting portion 603 and the second heat-conducting end 602. In order to improve the heat conduction efficiency between the ambient temperature measurement module and the second heat-conducting end 602, the ambient temperature measurement module can be fixed to the second heat-conducting end 602 by bonding with a heat-conducting adhesive. In addition, you can continue to refer to Figure 22b A flat mounting surface of a certain size may also be provided at the second heat-conducting end 602 , which may provide a mounting plane for the ambient temperature measurement module to be installed on the heat-conducting structure 6 , thereby facilitating the installation and fixation of the ambient temperature measurement module.

[0139] It is worth mentioning that in order to improve the structural stability of the housing 1 of the wearable device and to facilitate the arrangement of the functional modules in the accommodating space 103, reference may be made to Figure 22b A bracket 105 may also be provided on one side of the connecting wall 1012 of the housing 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 .

[0140] Reference Figure 23 , Figure 23 The figure illustrates the relative positional relationship between the heat-conducting structure 6, the connecting wall 1012, and the bracket 105. The connecting portion of the heat-conducting structure 6 can be embedded in the bracket 105, thereby concealing the connecting portion of the heat-conducting structure 6 within the bracket 105. This reduces the footprint of the heat-conducting structure 6 within the accommodation space 103. Furthermore, by embedding the heat-conducting structure 6 within the bracket 105, the bracket 105 can also provide support for the heat-conducting structure 6, reducing the need for structural strength. This allows the heat-conducting structure 6 to be made of a material with a higher thermal conductivity, thereby improving the accuracy of its temperature detection. It is understood that to conceal the heat-conducting structure 6 within the connecting wall 1012 and the bracket 105, the heat-conducting structure 6 can be, but is not limited to, manufactured using insert injection molding.

[0141] exist Figure 23In the illustrated embodiment, the first circuit board 3021 of the ambient temperature measurement module can be secured to the second heat-conducting end 602 via thermally conductive adhesive 303, and the first temperature sensor 301 is disposed on the side of the first circuit board 3021 facing away from the second heat-conducting end 602. Furthermore, foam 7 is attached to the surface of the first temperature sensor 301 facing away from the second heat-conducting end 602. This foam 7 provides protection and shock absorption for the entire ambient temperature measurement module. In other embodiments, the first temperature sensor 301 can be secured to the second heat-conducting end 602 via thermally conductive adhesive 303, while the first circuit board 3021 is disposed on the side of the first temperature sensor 301 facing away from the second heat-conducting end 602. In this case, the foam 7 can be disposed on the side of the first circuit board 3021 facing away from the second heat-conducting end 602. It can be understood that in the present application, the relative position relationship among the first circuit board 3021, the first temperature sensor 301 and the second heat-conducting end 602 is not limited. Those skilled in the art can reasonably arrange them according to 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 they should all be understood to fall within the scope of protection of the present application.

[0142] It is understandable that, in the present application, foam 7 may be attached to the skin-attached temperature measurement module to protect and reduce shock to the skin-attached temperature measurement module. Figures 21 to 23 In the illustrated embodiment, the specific configuration of the ambient temperature measurement module and the skin-tight temperature measurement module, as well as the method for achieving human body temperature measurement, can be configured with reference to the above embodiments and will not be described in detail here.

[0143] As can be seen from the description of 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 used to obtain a more accurate human body temperature. Since the side of the connecting wall 1012 facing away from the accommodating space 103 is in direct contact with the external environment, in some possible embodiments of the present application, the connecting wall 1012 can also be used as a heat-conducting structure, and the portion of the connecting wall 1012 located outside the accommodating space 103 can be used as a first heat-conducting end, and the portion of the connecting wall 1012 located inside the accommodating space 103 can be used as a second heat-conducting end. This can effectively simplify the structure of the wearable device and facilitate the collection of the ambient temperature.

[0144] When implementing it, please refer to Figure 24 , Figure 24A schematic diagram of a partial structure of a wearable device according to a possible embodiment of the present application is shown. In this embodiment, the connecting wall 1012 can be made of, but is not limited to, metal materials such as stainless steel, titanium alloy, aluminum alloy, cobalt-based alloy, nickel-based alloy, iron-based alloy, platinum alloy, and titanium-tantalum alloy. It can also be made of non-metallic materials such as ceramics to ensure that the connecting wall 1012 has a high thermal conductivity.

[0145] The first circuit board 3021 of the ambient temperature measurement module is located on one side of the connecting wall 1012 located in 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, thereby supporting the first temperature sensor 301. In addition, the first temperature sensor 301 can be bonded to the connecting wall 1012 via thermally conductive adhesive. In this case, the first circuit board 3021 can simultaneously support the first temperature sensor 301 and the thermally conductive adhesive. In this embodiment of the present application, the ambient temperature collected by the first thermally conductive end of the connecting wall 1012 can be transmitted to the first temperature sensor 301 via the second thermally conductive end and the thermally conductive adhesive. Because there is a circuit connection between the first temperature sensor 301 and the first circuit board 3021, the temperature data can be transmitted to the first circuit board 3021.

[0146] It is understood that since the surface area of ​​the connecting wall 1012, which serves as the first heat-conducting end, is larger, its area in contact with the environment is larger, thereby facilitating improved accuracy in ambient temperature measurement by the connecting wall 1012. Furthermore, the overall volume of the connecting wall 1012 is larger, thus providing more stable ambient temperature measurement.

[0147] You can continue to refer to Figure 24 In some other possible embodiments of the present 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. In addition, by providing 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 when the connecting wall 1012 is subjected to external forces can be effectively avoided.

[0148] In another embodiment of the present application, a certain distance may be provided between the first temperature sensor 301 and the connecting wall 1012. For example, the minimum distance between the two is between 0.3 and 1.3 mm. This effectively shortens 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. Furthermore, by providing 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 caused by external forces acting on the connecting wall 1012 can be reduced.

[0149] It is understandable that in Figure 24 In the illustrated embodiment, the specific configuration of the ambient temperature measurement module and the skin-tight temperature measurement module, as well as the method for achieving human body temperature measurement, can be configured with reference to the above embodiments and will not be described in detail here.

[0150] By using the wearable device provided by the present application, by setting 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. In addition, a skin-tight temperature measurement module is set on the first housing 101 to obtain a relatively accurate skin temperature through the skin-tight temperature measurement module. In this way, the ambient temperature data measured by the ambient temperature measurement module and the skin temperature data measured by the skin-tight temperature measurement module can be used as input, and the human body temperature can be obtained through calculation by the algorithm. By comprehensively considering the ambient temperature and skin temperature, the accuracy of human body temperature measurement can be effectively improved.

[0151] It is understandable that the solution for measuring human body temperature provided in the above embodiments of the present application can be used in addition to wearable devices, and can also be used in other commonly used electronic devices. For example, it can be used in mobile phones, speakers, televisions, sweeping robots or routers, etc., so that they have the function of measuring human body temperature. Among them, in these electronic devices, the ambient temperature measurement module and the skin-mounted temperature measurement module can be set with reference to any of the above embodiments, and will not be described in detail here. In addition, through reasonable design, the above electronic devices can also be enabled to measure the ambient temperature independently.

[0152] The above are only specific embodiments of the present application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
