[0042] In order to facilitate the understanding of the wearable device provided in the embodiment of the present application, its application scenario is first described below. The wearable device provided in the present application can be used for human health monitoring. Wearable devices such as smart watches or smart bracelets with the function of monitoring human health are one of the important products for mobile and online health monitoring and are widely praised by users. Therefore, the wearable device provided in the present application can be, but is not limited to, portable electronic devices such as smart watches and smart bracelets.

[0043] Take smart watches as an example, which can usually be worn on the wrist of the user. In this way, the electrocardiograph (ECG) can be set on the smart watch to conveniently detect the electrocardiogram of the human body. By calculating the electrocardiogram obtained by ECG measurement, human indicators such as heart rate, heart rate variability (HRV), and blood pressure can be obtained. Thereby, the body state can be predicted to effectively avoid obstacles to the conduction system of the heart or myocardial lesions. In addition, body temperature is also an important health indicator of the human body. By measuring the body temperature of the human body, the health state of the body can also be predicted, which can effectively reduce the risk of dangerous diseases.

[0044] In current wearable devices such as smart watches, an ECG module and a body temperature measurement module are usually provided at the same time. Since the detection of electrocardiogram and body temperature usually requires contact with human skin, the ECG module and the body temperature measurement module can be provided on the side of the wearable device that contacts the human body.

[0045] Reference Figure 1 , Figure 1 A schematic diagram of the structure of a wearable device provided by an embodiment of the present application is shown. The wearable device may include a housing having a first shell 1 and a second shell. The first shell 1 is disposed opposite to the second shell. In addition, the first shell 1 and the second shell are snapped together to form a storage space for accommodating the functional modules of the wearable device between the first shell 1 and the second shell. In the present application, when the wearable device is worn, the first shell 1 can be in contact with the human body, and the ECG module and the body temperature measurement module can be disposed close to the first shell 1.

[0046] Reference Figure 2 , Figure 2 An exploded view of a first shell 1 of an existing wearable device provided in one embodiment of the present application. In the present application, for the convenience of description, the surface of the first shell 1 that contacts the human body can be defined as the first surface 1a of the first shell 1, and the surface of the first shell 1 that faces the accommodating space can be defined as the second surface 1b of the first shell 1, and the first surface 1a and the second surface 1b are arranged opposite to each other. In addition, the connection surface of the first shell 1 that connects the first surface 1a and the second surface 1b can also be defined as the side surface 1c of the first shell 1.

[0047] Continue to refer to Figure 2 In this embodiment, the first shell 1 includes a fixing portion 101 and a detecting portion 102. The fixing portion 101 may be provided with a mounting hole 1011. Exemplarily, the fixing portion 101 may be a ring-shaped structure. The detecting portion 102 may be installed in the mounting hole 1011 of the fixing portion 101, and the detecting portion 102 is fixedly connected to the fixing portion 101. In this embodiment of the present application, the material of the fixing portion 101 may be plastic, ceramic, glass, etc., and the material of the detecting portion 102 may be plastic, ceramic, glass, etc. The materials of the fixing portion 101 and the detecting portion 102 may be the same or different.

[0048] The ECG module may generally include ECG electrodes 2a. Figure 2 In the illustrated embodiment, the ECG electrode 2a may be disposed on the first surface 1a of the first housing 1, and the ECG electrode 2a may be disposed along the edge of the first surface 1a. In addition, the ECG electrode 2a disposed on the first surface 1a may be led to the second surface by routing on the side surface 1c of the first housing 1, thereby achieving electrical connection between the ECG electrode 2a and the portion of the ECG module disposed in the accommodation space.

[0049] In addition, Figure 2 In the illustrated embodiment, when the body temperature measurement module is specifically set up, a heat-conducting column or other structure (not shown in the figure) may be embedded in the fixed portion 101 to conduct the detected human body temperature to the portion of the body temperature measurement module located in the accommodating space through the heat-conducting column, thereby achieving body temperature measurement.

[0050] Reference Figure 3 , Figure 3 This is a schematic diagram of the structure of a first housing 1 of an existing wearable device provided in another embodiment of the present application. In this embodiment, the ECG electrode 2a can be embedded in the fixing portion 101, and the ECG electrode 2a can extend to the accommodation space and be electrically connected to other parts of the ECG module. Figure 3 In the illustrated embodiment, the detection portion 102 may be made of sapphire glass having a high thermal conductivity, and the human body temperature detected by the sapphire glass may be conducted to the portion of the body temperature measurement module located in the accommodation space to achieve body temperature measurement.

[0051] By the above Figure 2 and Figure 3 It can be seen from the embodiments shown that in the existing wearable devices with both electrocardiogram and body temperature detection functions, the ECG module and the body temperature measurement module need to be set separately, which occupies a large space in the wearable device, thereby affecting the design requirements of miniaturization and thinness of the wearable device.

[0052] The wearable device provided by the present application aims to solve the above problems, by integrating the ECG module and the body temperature measurement module, saving the setting space of the modules for realizing the electrocardiogram and body temperature detection functions. It is conducive to realizing the miniaturization and thinness design of the wearable device. In addition, space can be reserved for the setting of other functional modules to increase the functional diversity of the wearable device.

[0053] In order to make the objectives, technical solutions and advantages of the present application more clear, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0054] The terms used in the following embodiments are only for the purpose of describing specific embodiments, and are not intended to be used as limitations on the present application. As used in the specification and the appended claims of the present application, the singular expressions "one", "a kind of", "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 represent: 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 objects associated before and after are in an "or" relationship.

[0055] References to "one embodiment" or "some embodiments" etc. described in this specification mean that a particular feature, structure or characteristic described in conjunction with the embodiment is included in one or more embodiments of the present application. Thus, the phrases "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear at different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0056] Reference Figure 4 , Figure 4 A schematic diagram of the structure of a wearable device provided for a possible embodiment of the present application. In this embodiment, the first shell 1 of the wearable device may be an integrally formed structure. The material of the first shell 1 may be, but is not limited to, ceramic, glass, or plastic. By setting the first shell 1 as an integrally formed structure, the structural reliability of the first shell 1 can be effectively improved, thereby improving the structural stability of the entire wearable device. In addition, by setting the first shell 1 as an integrated structure, the degree of integration of the wearable device can also be improved, thereby improving the appearance of the wearable device.

[0057] exist Figure 4 In the illustrated embodiment, the wearable device is provided with an ECG electrode 2a, which can be provided on the first surface 1a of the first shell 1. In the present application, the ECG electrode 2a may include, but is not limited to, a material having thermal conductivity and electrical conductivity such as silicon carbide or silver. In a possible embodiment of the present application, the ECG electrode 2a may include a resin material substrate, and a filler having thermal conductivity and electrical conductivity such as silicon carbide or silver doped in the resin material substrate, so that the ECG electrode 2a can be used to transmit electrical signals and to transmit temperature signals. In addition, the ECG electrode 2a may be formed on the first surface 1a of the first shell 1 by, but is not limited to, physical vapor deposition (PVD), printing, and slurry sintering.

[0058] You can continue to refer to Figure 4 In the present application, the shape of the ECG electrode 2a is not specifically limited. For example, it can be set as follows Figure 4 The arc shape shown can also be set to other regular shapes such as a circle, a square, or some possible irregular shapes. In addition, the number of ECG electrodes 2a can be one or more. For example, when there are two ECG electrodes 2a, the two ECG electrodes 2a can be set to Figure 4The arc shown in the figure is symmetrically arranged to improve the aesthetics of the ECG electrode 2a. In other possible embodiments of the present application, when there are multiple ECG electrodes 2a, the shapes of the multiple ECG electrodes 2a may be different, and they may be designed according to the space available for setting the ECG electrodes 2a on the first surface 1a of the first shell 1. It can be understood that by arranging multiple ECG electrodes 2a on the first surface 1a of the first shell 1, multi-point measurement can be achieved, which can effectively improve the stability and reliability of electrocardiogram and body temperature detection, thereby facilitating improving the accuracy of electrocardiogram and body temperature detection.

[0059] In addition, the ECG electrode 2a can be set at any position of the first surface 1a, and illustratively, it can be set in the central area of ​​the first surface 1a. The wearable device provided by this solution has no requirements for the setting position of the ECG electrode 2a on the first surface 1a, which can effectively reduce the difficulty of process control of the ECG electrode 2a. In a possible embodiment of the present application, the area of ​​the first surface 1a for setting the ECG electrode 2a can also be made to bulge in the direction away from the accommodating space to facilitate reliable contact between the ECG electrode 2a and the human body.

[0060] You can continue to refer to Figure 4 The first shell 1 is also provided with a via 103, which passes through the first shell 1 in the direction from the first surface 1a to the second surface. In the present application, the via 103 may be formed by, but is not limited to, computerized numerical control (CNC), laser drilling, or directly formed by a mold forming process. The ECG electrode 2a covers the via 103. It can be understood from the introduction of the formation process of the ECG electrode 2a in the above embodiment that in the process of forming the ECG electrode 2a by PVD, part of the material used to form the ECG electrode 2a can pass through the via 103 and spread to the second surface of the first shell 1.

[0061] The specific shape of the via hole 103 is not limited in the present application. For example, it can be a hole of a regular shape such as a circle, square or triangle, or it can be a hole of some possible irregular shape. In addition, it can be understood that the smaller the aperture of the via hole 103, the smaller the impact on the appearance of the first shell 1, and it is easier to meet the waterproof performance requirements of the first shell 1. However, if the aperture of the via hole 103 is too small, it is not conducive to the material used to form the ECG electrode 2a to pass through the via hole 103. In a possible embodiment of the present application, the aperture of the via hole 103 can be 0.1mm to 5mm, and for example, it can be 0.2mm, 0.5mm, 0.7mm, 1.0mm or 3mm, etc. Thereby, on the basis of satisfying the appearance of the first shell 1, it is easy to achieve the waterproof design of the first shell 1.

[0062] Reference Figure 5 , Figure 5 A schematic diagram of the structure of the second surface 1b of the first shell 1 of an embodiment of the present application is shown. It is understandable that in the present application, the material of the ECG electrode 2a can fill the entire via 103 to block the via 103; or it can be formed only on the hole wall of the via 103. As long as the part of the ECG electrode 2a formed on the first surface 1a and the part formed on the second surface 1b can be connected. For ease of description, in the present application, the part of the ECG electrode 2a located on the first surface 1a can be referred to as the first detection end 201, the part of the ECG electrode 2a located on the second surface 1b can be referred to as the second detection end 202, and the part of the ECG electrode 2a that penetrates the via 103 can be referred to as the connecting portion. It is understandable that the first detection end 201 and the second detection end 202 are connected through the connecting portion.

[0063] You can continue to refer to Figure 5 The present application does not specifically limit the shape of the second detection end 202. For example, it can be Figure 5 In some other embodiments, it may be a regular shape such as an ellipse, a triangle, a rectangle, or some possible irregular shape. In addition, the present application does not limit the area of ​​the second detection terminal 202. For example, the area of ​​the second detection terminal 202 may be larger than the cross-sectional area of ​​the via 103, so as to facilitate the electrical connection between the second detection terminal 202 and other devices located in the accommodation space of the wearable device, thereby achieving electrical connection between the entire ECG electrode 2a and other devices located in the accommodation space of the wearable device.

[0064] From the introduction of the above embodiments, it can be known that in the present application, there can be multiple ECG electrodes 2a, and a via 103 can be set for each ECG electrode 2a to achieve electrical connection between each ECG electrode 2a and other devices located in the storage space of the wearable device. In addition, the number of vias 103 set for each ECG electrode 2a can be the same or different, and can be specifically set according to the connection relationship between the ECG electrode 2a and the device in the storage space of the wearable device.

[0065] In order to realize the electrocardiogram and body temperature detection functions of the wearable device, the wearable device provided by the present application may further include a circuit board 3. Figure 6 , Figure 6An exploded view of the local structure of a wearable device provided in one embodiment of the present application. In this embodiment, the circuit board 3 can be arranged in the accommodation space of the wearable device. The circuit board 3 can be exemplarily a printed circuit board (PCB) or a flexible printed circuit (FPC). The circuit board 3 can integrate an ECG module and a temperature measurement module such as a functional module for realizing electrocardiogram and body temperature detection, a control module, a processing module or a storage module.

[0066] The circuit board 3 is usually provided with metal traces, and each metal trace can be electrically connected to the above-mentioned various modules integrated in the circuit board 3. Figure 6 The circuit board 3 is also provided with a contact 4. In a possible embodiment of the present application, the portion of the metal trace formed on the surface of the circuit board 3 can be used as the contact 4. Alternatively, the covering on the surface of the circuit board 3 is etched away to expose the corresponding metal trace, and the exposed portion of the metal trace is used as the contact 4. This enables electrical connection between the contact 4 and the metal trace, and further electrical connection between the contact 4 and various modules.

[0067] It can be understood that the above-mentioned configuration of the contacts 4 is only an exemplary description given in some possible embodiments of the present application. In other embodiments of the present application, the contacts 4 may also be configured in other possible ways, which are not listed here one by one.

[0068] In the present application, the contact 4 can be electrically connected to the ECG module in the circuit board 3, so that the ECG electrode 2a can be connected to the Figure 5 The second detection end 202 is electrically connected to the contact 4 to achieve electrical connection between the entire ECG electrode 2a and the circuit board 3. Figure 7 , Figure 7 for Figure 4 In this embodiment, a thermal conductive adhesive 5 may be provided between the second detection end 202 of the ECG electrode 2a and the contact 4, so as to electrically connect the second detection end 202 to the contact 4 through the thermal conductive adhesive 5. It is understandable that while the thermal conductive adhesive 5 is used to connect the second detection end 202 and the contact 4, the thermal conductive adhesive 5 may also be used to block the via 103, thereby achieving sealing of the via 103, so as to achieve a waterproof effect for the entire first housing 1.

[0069] The above embodiment is only an exemplary description of the electrical connection between the second detection end 202 and the contact 4. In some other possible embodiments of the present application, the second detection end 202 and the contact 4 can also be electrically connected by a lead, a spring or other possible structure with thermal and electrical conductivity. In addition, the via 103 can also be waterproofed and sealed by applying waterproof glue.

[0070] Since the thermally conductive and electrically conductive adhesive 5 has good thermal and electrical conductivity, it can be used not only to transmit the electrical signal collected by the ECG electrode 2a to the contact 4, but also to conduct the temperature collected by the ECG electrode 2a to the circuit board 3. Since the ECG electrode 2a is also formed of a material having thermal and electrical conductivity, in some possible embodiments of the present application, the ECG electrode 2a and the thermally conductive and electrically conductive adhesive 5 may contain the same material having thermal and electrical conductivity to improve the efficiency of the ECG electrode 2a in transmitting electrical signals and conducting temperature through the thermally conductive and electrically conductive adhesive 5. In some other embodiments of the present application, the ECG electrode 2a and the thermally conductive and electrically conductive adhesive 5 contain different materials having thermal and electrical conductivity, as long as the ECG electrode 2a can transmit electrical signals and conduct temperature through the thermally conductive and electrically conductive adhesive 5.

[0071] Can be referred to together Figure 6 and Figure 7 In the present application, a temperature sensor 6 may also be provided on the circuit board 3, and the temperature sensor 6 is electrically connected to the circuit board 3. In the present application, the electrical connection between the temperature sensor 6 and the circuit board 3 may be achieved by the electrical connection between the temperature sensor 6 and the metal traces in the circuit board 3. In addition, the temperature sensor 6 may be fixed to the circuit board 3, and the fixing method may be, but is not limited to, welding or bonding.

[0072] You can continue to refer to Figure 7 In the present application, the second detection end 202 of the ECG electrode 2a can also be in thermal contact with the temperature sensor 6, and the contact mode can be direct contact or indirect contact. In a possible embodiment of the present application, the thermal conductive adhesive 5 can also be arranged between the temperature sensor 6 and the second detection end 202, and the second detection end 202 and the temperature sensor 6 are connected through the thermal conductive adhesive 5. It can be understood that the thermal conductive adhesive 5 can also have an adhesive property, so that the temperature sensor 6 can be bonded and fixed to the circuit board 3 through the thermal conductive adhesive 5.

[0073] In the wearable device provided in the present application, the ECG electrode 2a can extend from the first surface 1a of the first shell 1 to the second surface 1b through the via 103 penetrating the first shell 1. In addition, since the ECG electrode 2a is formed of a material having thermal and electrical conductivity, and the second detection end 202 of the ECG electrode 2a is electrically connected to the contact 4 on the circuit board 3 through the thermal and electrical conductive adhesive 5. In this way, the electrocardiogram signal detected by the ECG electrode 2a can be transmitted to the contact 4 through the thermal and electrical conductive adhesive 5, and the electrocardiogram signal is analyzed and processed by the ECG module connected to the contact 4, thereby obtaining corresponding electrocardiogram data, so as to realize the detection of the electrocardiogram of the human body. The second detection end 202 of the ECG electrode 2a is connected to the temperature sensor 6 on the circuit board 3 through the thermally conductive and electrically conductive adhesive 5. The temperature signal collected by the first detection end 201 of the ECG electrode 2a can be transmitted to the second detection end 202 through the connecting portion 203 arranged in the via 103, and transmitted to the temperature sensor 6 through the thermally conductive and electrically conductive adhesive 5. Then, the temperature signal is analyzed and processed by the body temperature measurement module integrated in the circuit board 3 for realizing temperature detection to obtain the temperature data of the human body, thereby realizing the detection of the body temperature of the human body.

[0074] By using the wearable device provided in the embodiment of the present application, the functions of electrocardiogram detection and body temperature detection can be integrated through the ECG electrode 2a with thermal and electrical conductivity, which can effectively save the setting space of the module for realizing the electrocardiogram detection and body temperature detection functions. This is conducive to the miniaturization and thinness of the wearable device. In addition, by integrating the electrocardiogram detection and body temperature detection functions, space can be reserved for the setting of other functional modules of the wearable device, which is conducive to the realization of the diversified functional design of the wearable device to enhance the user experience.

[0075] From the above description of the embodiment, it can be known that the ECG electrode 2a is formed of a material having thermal and electrical conductivity. In a possible embodiment of the present application, the charging function of the wearable device can also be integrated into the ECG electrode 2a. In the specific implementation, reference can be made to Figure 8 , Figure 8 An exploded view of a partial structure of a wearable device implemented in the present application is shown. In this embodiment, a charging pin 7 may also be provided on the circuit board 3, and the charging pin 7 is electrically connected to the circuit board 3. In the present application, the electrical connection between the charging pin 7 and the circuit board 3 may be achieved by the electrical connection between the charging pin 7 and the metal trace in the circuit board 3. In addition, the metal trace in the circuit board 3 electrically connected to the charging pin 7 may also be electrically connected to a charging module, which may be, but is not limited to, provided on the circuit board 3. In this way, the wearable device may be charged by the electrical connection between an external charging device and the charging pin 7.

[0076] Please refer to Fig. 9 , Fig. 9 for Figure 4 In the cross-sectional view at BB in the middle, in the present application, the charging pin 7 can be fixed to the circuit board 3, and the fixing method thereof can be but is not limited to welding or bonding. Fig.10 , Fig.10 for Fig. 9 An enlarged view of the local structure at C in the middle. In this embodiment of the present application, the length of the charging pin 7 can be designed so that it can directly contact the second detection end 202 of the ECG electrode 2a, thereby effectively reducing the charging resistance of the wearable device and improving the charging efficiency. In addition, in order to improve the reliability of the contact between the charging pin 7 and the second detection end 202, the charging pin 7 can be set as a spring, or the charging pin 7 can be made of an elastic material, so that the charging pin 7 and the second detection end 202 can achieve stable contact through the elastic contact force.

[0077] In a possible embodiment of the present application, the charging pin 7 can also be electrically connected to the second detection end 202 of the ECG electrode 2a through a lead, and the material, thickness and other parameters of the lead can be adjusted to achieve the purpose of reducing impedance. In some other embodiments of the present application, the thermal conductive adhesive 5 can also be arranged between the charging pin 7 and the second detection end 202, and the second detection end 202 and the charging pin 7 are connected through the thermal conductive adhesive 5. It can be understood that the thermal conductive adhesive 5 can also have adhesive properties, so that the charging pin 7 can be bonded and fixed to the circuit board 3 through the thermal conductive adhesive 5 to improve the reliability of the connection between the charging pin 7 and the circuit board 3.

[0078] It is understandable that the connection method between the charging pin 7 and the second detection terminal 202 provided in the above embodiment is only some exemplary descriptions given in this application. In other possible embodiments of this application, other possible connection methods can be adopted between the two, which are not listed one by one here. As long as a stable electrical connection between the charging pin 7 and the second detection terminal 202 can be achieved, they should be understood to fall within the protection scope of this application.

[0079] In the present application, since the ECG electrode 2a is formed of a material having thermal and electrical conductivity, and the second detection end 202 of the ECG electrode 2a is electrically connected to the charging pin 7 on the circuit board 3. In this way, the first detection end 201 of the ECG electrode 2a can be electrically connected to an external charging device, so that the current generated by the external charging device enters the ECG electrode 2a through the first detection end 201, and is transmitted to the charging pin 7 through the second detection end 202 of the ECG electrode 2a, and then the charging module electrically connected to the charging pin 7 in the circuit board 3 is used to charge the wearable device.

[0080] Some current wearable devices may also be provided with an antenna module (not shown in the figure) to achieve wireless communication between the wearable device and other external terminal devices. The antenna module and the devices in the wearable device can realize the function of the antenna by being electrically connected. Since the ECG electrode 2a has conductive properties, in some possible embodiments of the present application, the antenna module may be provided on the circuit board 3. In addition, the antenna module may be electrically connected to the contacts exposed on the surface of the circuit board 3 through the metal traces in the circuit board 3. For ease of distinction, in this embodiment of the present application, the contacts electrically connected to the ECG module may be referred to as first-class contacts, and the contacts electrically connected to the antenna module may be referred to as second-class contacts.

[0081] In this embodiment, the ECG electrode 2a can be electrically connected to the second type of contact on the circuit board 3 to integrate the antenna function into the ECG electrode 2a, so that the antenna signal is received or transmitted through the first detection end 201 of the ECG electrode 2a disposed on the first surface 1a of the first housing 1. It is understandable that the ECG electrode 2a and the second type of contact can be electrically connected through, but not limited to, a structure having thermal and electrical conductivity such as a thermal conductive adhesive 5, a lead or a spring.

[0082] By using the wearable device provided in this embodiment of the present application, the electrocardiogram detection, body temperature detection, charging function and antenna function can be integrated through the ECG electrode 2a, which can effectively save the setting space of the modules used to realize the electrocardiogram detection, body temperature detection, charging function and antenna function. This is conducive to the miniaturization and thinness of the wearable device. In addition, by integrating the electrocardiogram detection, body temperature detection and charging functions, space can be reserved for the setting of other functional modules of the wearable device, which is conducive to the realization of the diversified functional design of the wearable device to enhance the user experience.

[0083] It can be understood from the introduction of the setting method of the via 103 in the above embodiment of the present application that in a possible implementation of the present application, the via 103 can be opened respectively for each function, so as to electrically connect the corresponding contact 4, temperature sensor 6 or charging pin 7 on the circuit board 3 with the corresponding via 103. In some other embodiments of the present application, at least two functions can be realized by opening one via 103. In this case, the area of ​​the second detection end 202 of the ECG electrode 2a corresponding to the via 103 can be set larger.

[0084] Reference Fig.11 , Fig.11An exploded view of the first shell 1 of a wearable device provided for another possible embodiment of the present application. In this embodiment, the first shell 1 includes a fixing portion 101 and a detecting portion 102, wherein the fixing portion 101 may be provided with a mounting hole 1011. Exemplarily, the fixing portion 101 may be an annular structure. The detecting portion 102 may be mounted in the mounting hole 1011 of the fixing portion 101, and the detecting portion 102 is fixedly connected to the fixing portion 101. In this embodiment of the present application, the materials of the fixing portion 101 and the detecting portion 102 may be the same or different. Exemplarily, the material of the fixing portion 101 may be plastic, ceramic, glass, etc., and the material of the detecting portion 102 may be plastic, ceramic, glass, etc.

[0085] In this embodiment of the present application, the ECG electrode 2a is arranged on the detection part 102, and the detection part 102 can protrude from the fixing part 101 in the direction away from the accommodating space of the wearable device, so as to achieve reliable contact between the ECG electrode 2a and the human body, thereby improving the accuracy of detection.

[0086] It is understandable that the use of Fig.11 The specific configuration of other structures of the wearable device of the first shell 1 shown, as well as the process of realizing electrocardiogram detection, body temperature detection, charging function and antenna function can refer to any of the above embodiments and will not be described in detail here.

[0087] The above embodiment of the present application provides a setting method of extending the ECG electrode 2a from the first surface 1a to the second surface 1b by opening a hole 103 on the first shell 1. In addition to being used for the first shell 1, it can also be used for the setting of other structures of the wearable device. For example, we know that the detection of electrocardiogram usually requires the formation of a circulation loop passing through the heart in the human body. Therefore, in addition to setting the ECG electrode 2a in the first shell 1, the ECG electrode can also be set in an area that can still be touched after the wearable device is worn on the human body. For example, referring to Fig.12 , Fig.12 The structure of the second shell 8 side of the wearable device of the embodiment of the present application is shown. In this embodiment, an ECG electrode 2b can be set on the second shell 8 of the outer shell of the wearable device. Still taking the wearable device as a smart watch as an example, when the smart watch is worn on the left hand of the human body, the ECG electrode 2a set on the first shell 1 can contact the left hand, and the right hand of the human body can contact the ECG electrode 2b set on the second shell 8, thereby forming an electrocardiogram detection path.

[0088] The second shell 8 of the wearable device may include a display screen 81, which can be used to display the test results of the electrocardiogram, body temperature, etc., as well as the power or signal status of the wearable device, so that the user can intuitively know his or her own health status and the working status of the wearable device. In a possible embodiment of the present application, an ECG electrode 2b can be set in the display area of ​​the display screen 81 of the second shell 8. At this time, the ECG electrode 2b can be formed of a transparent material with thermal and electrical conductivity. In some other possible embodiments of the present application, the ECG electrode 2b can also be set in the non-display area of ​​the display screen 81 of the second shell 8. At this time, there is no requirement for the transparency of the material of the ECG electrode 2b, as long as it has good thermal and electrical conductivity.

[0089] Reference Fig.13 , Fig.13 Shown Fig.12 An exploded diagram of the wearable device shown in . In a possible embodiment of the present application, the surface of the display screen 81 of the second shell 8 that is used for display can be defined as the first surface 81a of the display screen 81, and the surface of the display screen 81 that faces the accommodating space can be defined as the second surface 81b of the display screen 81. The display screen 81 is also provided with a via 8101, and the via 8101 penetrates the display screen 81 in the direction from the first surface 81a to the second surface 81b. The ECG electrode 2b can extend from the first surface 81a of the display screen 81 to the second surface 81b of the display screen 81 through the via 8101, thereby realizing the connection between the ECG electrode 2b and the circuit board located in the accommodating space.

[0090] It is understood that the connection between the ECG electrode 2b of the display screen 81 of the second housing 8 and the circuit board can refer to the above-mentioned example. Figure 7 In the embodiment shown, the connection mode between the ECG electrode 2a of the first shell 1 and the circuit board 3 is set. For example, contacts 4 and the like can be formed on the circuit board, which will not be described in detail here. In addition, the ECG electrode 2b on the display screen 81 and the ECG electrode 2a on the first shell 1 can be electrically connected to the same circuit board 3, or to different circuit boards 3, which can be designed according to the specific layout mode in the accommodation space of the wearable device.

[0091] Similar to the side of the first shell 1, the ECG electrode 2b provided on the display screen 81 can also be formed of a heat-conductive and electrically conductive material. In this way, the ECG electrode 2b can also be connected to a temperature sensor provided on a circuit board through a structure having heat-conductive and electrically conductive properties such as a heat-conductive and electrically conductive adhesive, a lead or a shrapnel, so as to detect the ambient temperature through the ECG electrode 2b. With this solution, the electrocardiogram detection and ambient temperature detection functions can be integrated through the ECG electrode 2b provided on the second shell 8. While adding the ambient temperature detection function to the wearable device, it can also avoid occupying too much space of the wearable device. It has little impact on the miniaturization design of the wearable device and can enhance the user experience. In addition, the body temperature detected by the ECG electrode 2a of the first shell 1 can also be calibrated through the ambient temperature detected by the ECG electrode 2b to improve the accuracy of body temperature detection.

[0092] It is understandable that, when the wearable device is worn by the user, the display screen 81 may always be exposed. Based on this, in the present application, the antenna function of the wearable device may also be integrated on the ECG electrode 2b of the display screen 81 to provide the user with more options. Fig.14 , Fig.14 This is a schematic diagram of a partial structure of a wearable device according to a possible embodiment of the present application. Fig.14 In the embodiment, the ECG electrode 2b extends from the first surface 81a of the display screen 81 to the second surface 81b (see Fig.13 ), the contacts 4 on the circuit board 3 include second-type contacts. In addition, an antenna module (not shown in the figure) is provided on the circuit board 3, and the second-type contacts are electrically connected to the antenna module. In this embodiment of the present application, the portion of the ECG electrode 2b located on the second surface 81b can also be electrically connected to the second-type contact through the thermally conductive and electrically conductive adhesive 5, so that the antenna signal can be received or transmitted through the portion of the ECG electrode 2b provided on the first surface 81a of the display screen, so as to realize the antenna function of the wearable device.

[0093] It is worth mentioning that the part of the ECG electrode 2b located on the second surface 81b and the second type of contact can also be electrically connected through a structure with thermal and electrical conductivity such as a lead or a spring. Fig.14 In the embodiment shown, the charging function of the wearable device can be integrated into the ECG electrode 2b by setting a charging pin on the circuit board 3. The specific setting method can refer to the above embodiment and will not be repeated here.

[0094] You can continue to refer to Fig.13In this embodiment of the present application, the second shell 8 may further include a support frame 82, and the support frame 82 is located on the side of the display screen 81 facing the accommodating space, and the display screen 81 may be fixed to the support frame 82, so that the support frame 82 supports the display screen 81. The material of the support frame 82 may be, but is not limited to, metal or plastic. In addition, in the present application, in order to achieve the fixation of the first shell 1, the wearable device may further include a fixing frame 9, and the fixing frame 9 may be located on the side of the first shell 1 facing the accommodating space of the wearable device, and the first shell 1 is fixed to the fixing frame 9. The material of the fixing frame 9 may be, but is not limited to, metal or plastic, so as to provide reliable support for the first shell 1. In addition, the support frame 82 and the fixing frame 9 may be, but are not limited to, fastened and connected by fasteners.

[0095] In the present application, the support frame 82 may be provided in a ring-shaped structure so that the support frame 82 serves as part of the housing of the wearable device. The support frame 82 has a side wall, which can be used to connect the first shell 1 and the display screen 81, so that the side wall, the first shell 1 and the display screen 81 together form a closed accommodation space. When the wearable device is worn on the human body, since the side wall also has an area that can be touched, in some possible embodiments of the present application, the area of ​​the side wall of the support frame 82 that can be touched may also be provided with ECG electrodes.

[0096] Reference Fig.15 , Fig.15 for Fig.13 A stereoscopic diagram of the wearable device shown in . In this embodiment of the present application, the side surface of the side wall of the support frame 82 that can be seen by the user can be defined as the first surface 82a of the side wall, and the surface of the side wall facing the accommodating space can be defined as the second surface 82b of the side wall. In addition, the side wall can also be provided with a via 8201, and the via 8201 penetrates the side wall of the support frame 82 in the direction from the first surface 82a of the side wall to the second surface 82b. The ECG electrode 2c can extend from the first surface 82a of the side wall of the support frame 82 to the second surface 82b through the via 8201, thereby realizing the electrical connection between the ECG electrode 2c and the circuit board located in the accommodating space.

[0097] It is understandable that in this embodiment, the specific location and shape of the ECG electrode 2c on the side wall of the support frame 82 are not limited, and it can be adaptively adjusted according to the side wall structure of the support frame 82. In addition, the ECG electrode 2c arranged on the side wall of the support frame 82 can also be formed of a transparent material with thermal and electrical conductivity to improve the appearance of the wearable device.

[0098] exist Fig.15In the embodiment shown, the connection between the ECG electrode 2c provided on the side wall of the support frame 82 and the circuit board can be set by referring to the connection method between the ECG electrode 2a of the first housing 1 and the circuit board 3 in any of the above embodiments. For example, the contact 4 can be formed on the circuit board 3, which will not be described in detail here.

[0099] Similar to the side of the first shell 1, the ECG electrode 2c arranged on the side wall of the support frame 82 can also be formed of a thermally conductive and electrically conductive material. In this way, the ECG electrode 2c can also be connected to the temperature sensor arranged on the circuit board through a thermally conductive and electrically conductive adhesive to detect the ambient temperature through the ECG electrode 2c. With this solution, the electrocardiogram detection and ambient temperature detection functions can be integrated through the ECG electrode 2c arranged on the side wall of the support frame 82. While adding the ambient temperature detection function to the wearable device, it can also avoid occupying too much space of the wearable device. It has little impact on the miniaturization design of the wearable device and can enhance the user experience. In addition, the body temperature detected by the ECG electrode 2a of the first shell 1 can also be calibrated by the ambient temperature detected by the ECG electrode 2c to improve the accuracy of body temperature detection.

[0100] It is understandable that, based on the above embodiments, through reasonable design, the charging function and antenna function of the wearable device can also be integrated on the ECG electrode 2c on the side wall of the support frame 82 to provide users with more options.

[0101] It is worth mentioning that, with the wearable device provided in the present application, ECG detection can be achieved by setting ECG electrodes on any two structures among the first shell 1, the display screen 81 and the support frame 82. In addition, when ECG electrodes are set on the three structures of the first shell 1, the display screen 81 and the support frame 82, multiple ECG detection channels can be formed through reasonable design, and the multiple ECG detection channels can be calibrated with each other to improve the accuracy of the wearable device for ECG detection.

[0102] The wearable device provided by the present application can be provided with ECG electrodes on structures such as the first shell 1, the display screen 81 and the support frame 82, and the ECG electrodes are formed of heat-conductive and electrically conductive materials, so that the ECG detection, body temperature detection, charging function and antenna function are integrated through the ECG electrodes to achieve the miniaturization and thin design of the structure of the wearable device. In addition, by providing a via hole on the structure provided with the ECG electrode, the ECG electrode formed on one side surface of the structure is extended to the one side surface of the structure located in the accommodation space through the via hole, so as to facilitate the electrical connection between the ECG electrode and other devices in the accommodation space of the wearable device, and can effectively improve the aesthetics of the wearable device area provided with the ECG electrode.

[0103] It is understandable that the solution provided by the present application for integrating multiple functions through ECG electrodes can be used in other possible electronic devices in addition to being set in wearable devices. Exemplarily, it can be used in mobile phones, stereos, televisions, sweeping robots or routers, etc., to set ECG electrodes on the housings of these electronic devices in the above manner, and integrate electrocardiogram detection, body temperature detection, charging functions, antenna functions, etc. through ECG electrodes. It can realize the miniaturization and thinness design of electronic devices. And it can reserve space for the setting of other functional modules, thereby realizing the functional diversification of electronic devices.

Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
