[0002] The present application relates to the field of electronic technology, and in particular to a health monitoring module and electronic equipment. Background Art

[0003] Today, people are increasingly demanding more functionality from electronic devices. Users hope to integrate more health monitoring functions into compact devices. For example, users want devices that can not only monitor multiple indicators such as blood oxygen, electrocardiogram, heart rate, and blood pressure, but also analyze these indicators to create micro-physical examination modes or stress detection modes, making it easier for users to monitor their health. Therefore, achieving multifunctionality in electronic devices while ensuring miniaturization and portability has become an industry trend. Summary of the Invention

[0004] The present application provides a health monitoring module and an electronic device.

[0005] In a first aspect, an embodiment of the present application provides a health monitoring module. The health monitoring module includes a housing, an optical heart rate module, a circuit board, and a light-transmitting member. The housing is fixed to one side of the circuit board and together with the circuit board encloses a storage space. The housing is provided with a light-transmitting hole, which connects the storage space with the outside world. The housing includes a conductive part, which is made of conductive material. A part of the conductive part is exposed on the top surface of the housing, and the other part is electrically connected to the circuit board. The light-transmitting member is fixed to the housing and at least partially fills the light-transmitting hole. The optical heart rate module is located in the storage space, the optical heart rate module is fixed to the circuit board, and is electrically connected to the circuit board. The optical heart rate module and the light-transmitting hole are arranged relative to each other, and the optical heart rate module emits and receives light through the light-transmitting hole and the light-transmitting member.

[0006] It is understood that the housing is fixed to one side of the circuit board and, together with the circuit board, encloses a storage space. The optical heart rate module is located in the storage space. The housing can protect the optical heart rate module.

[0007] The housing has a light-transmitting hole that connects the storage space to the outside world. A light-transmitting member is fixed to the housing and at least partially fills the light-transmitting hole. The light-transmitting member seals the light-transmitting hole to prevent dust and other impurities from entering the storage space through the light-transmitting hole and interfering with the operation of the optical heart rate module.

[0008] The optical heart rate module can be used to collect the user's heart rate signal, such as a photoplethysmography (PPG) signal. When the user's finger presses the housing, the user's finger covers the light-transmitting hole, allowing light from the optical heart rate module to shine onto the user's finger through the light-transmitting hole. The light is then reflected or scattered by the blood vessels in the user's finger, returning to the storage space through the light-transmitting hole. It is received by the optical heart rate module, converted into an electrical signal through photoelectric conversion, and transmitted to the circuit board.

[0009] The light reflected or scattered by the blood vessels in the user's finger can reflect the user's blood flow information. Blood flow usually refers to the flow of blood in the blood vessels in the body. It is a basic parameter of the blood circulation system, reflecting the process of blood flowing through arteries, capillaries and veins under the action of the heart pumping blood. Blood flow can be characterized by a variety of parameters, including but not limited to speed, flow, direction, stability (whether the flow of blood in the circulatory system is stable), resistance (blood flow is affected by the resistance of the blood vessel wall), pulsatility (fluctuation of blood flow during the heartbeat), distribution (distribution of blood flow in the body), etc. By measuring and analyzing this blood flow information, the function of the heart and vascular system can be evaluated, cardiovascular disease can be diagnosed, and effective treatment plans can be formulated.

[0010] Blood flow information is interrelated and mutually influential with other physiological characteristics such as heart rate, blood oxygen, and respiration. In physiological characteristic detection, comprehensive consideration of this information helps to more accurately understand the body's physiological state and health status.

[0011] A portion of the conductive portion is exposed on the top surface of the housing. To measure an ECG, the user touches their finger to the top surface of the housing, electrically connecting the conductive portion. This allows the housing to collect the user's electrical signal. This signal is processed to produce the user's electrocardiogram (ECG) waveform, which can reflect the user's cardiac function.

[0012] The PPG signal can also be combined with the aforementioned ECG waveform to generate more accurate blood pressure and other biometric information related to the human cardiovascular system through algorithms. For example, the health monitoring module can simultaneously collect the user's ECG waveform and PPG signal, calculate the time difference (PPT) between the two through an algorithm, and then convert the difference using a formula to obtain the user's blood pressure data.

[0013] The housing can also be used to sense or detect a user's touch or press, enabling the health monitoring module to function as a key. For example, when a user touches or presses the conductive portion, the conductive portion can collect the user's electrical signal. Based on whether the conductive portion collects the user's electrical signal, it can be determined whether the user has touched or pressed the conductive portion.

[0014] The shell of the health monitoring module of the present application can be used to collect the user's electrical signals and obtain ECG signals. The optical heart rate module can be used to obtain the user's PPG signals. After the ECG signals and PPG signals are processed by corresponding algorithms, multiple physiological indicators such as the user's electrocardiogram, heart rate, and blood pressure can be obtained. In the traditional technical solution, the PPG acquisition device and the ECG acquisition device are set separately. The user needs to use two fingers to touch the PPG acquisition device and the ECG acquisition device at the same time to complete the acquisition of ECG signals and PPG signals. When the health monitoring module of the present application collects the user's ECG signals and PPG signals, the user only needs to place one finger on the top surface of the shell, which is easier to operate.

[0015] The health monitoring module integrates the button function and the health monitoring function. Compared with the solution of setting the button and health monitoring function modules separately, the health monitoring module of the present application has a smaller size while achieving multi-functions.

[0016] Furthermore, this application uses an ECG waveform combined with a PPG signal to measure a user's blood pressure. Compared to traditional blood pressure monitors, this device eliminates the need for an air pump or airbag, resulting in a smaller footprint. This health monitoring module allows users to simply place their finger on the housing to complete a blood pressure test, simplifying the process and making it more convenient for users.

[0017] In one embodiment, the health monitoring module further includes a pressure-sensing circuit and a pressure-sensing component. The pressure-sensing component is fixed to the side of the circuit board facing away from the housing, and the pressure-sensing circuit is fixed to the pressure-sensing component. When the housing is subjected to pressure and the pressure-sensing component deforms, the pressure-sensing circuit is used to detect the deformation of the pressure-sensing component.

[0018] It is understood that when a user places a finger on the housing to measure ECG and PPG signals, the pressure-sensing component may deform to varying degrees depending on the force acting between the user's finger and the housing. The pressure-sensing circuit can be used to detect this deformation of the pressure-sensing component. Thus, the degree of pressure-sensing component deformation detected by the pressure-sensing circuit can be used to determine the force with which the user's finger pressed the housing.

[0019] When the user's finger is placed in the wrong position on the housing, or the position where the finger is placed deviates from the ideal detection position, the force applied to the pressure-sensing component is small. The pressure-sensing chip can determine whether the user's finger is in place based on the force applied to the pressure-sensing component. During the operation of the pressure-sensing circuit and the pressure-sensing component, a first threshold value can be set. The first threshold value is the minimum force applied to the pressure-sensing component when the user's finger is in place. When the pressure-sensing chip monitors that the real-time force detected by the pressure-sensing component is greater than or equal to the first threshold value, the pressure-sensing chip can control the health monitoring module to start collecting the user's ECG and PPG signals at the same time, calculate the time difference between the two, that is, the pulse wave transmission time (PTT), and then convert it through a series of formulas to finally obtain the user's blood pressure data.

[0020] When the force between the user's finger and the housing is small, the depth of penetration of the light emitted by the light emitter into the tissue under the user's skin is limited, and the user's blood vessels are at a certain depth from the surface of the user's skin. Generally, the greater the force applied by the user to the housing, the better the fit between the finger and the keycap, and the deeper the light emitted by the light emitter penetrates the user's skin. Therefore, when the health monitoring module is used to measure the PPG signal, a second threshold value can be set. When the force between the user's finger and the housing is greater than or equal to the second threshold value, the light emitted by the light emitter penetrates the user's skin to a greater depth, allowing most of the light to illuminate the location of the blood vessels under the user's skin. When the pressure sensing chip monitors that the real-time force detected by the pressure sensing component is greater than or equal to the second threshold value, the pressure sensing chip controls the health monitoring module to start collecting the user's PPG signal, so that the collected PPG signal is more accurate.

[0021] In addition, when the real-time force detected by the pressure sensing component is greater than or equal to the second threshold value, the pressure sensing chip controls the health monitoring module to start collecting the user's ECG signal, so that the force between the user and the shell is within a larger range, and the electrical connection reliability between the shell and the user is better, so that the collected ECG signal is more accurate.

[0022] Furthermore, the pressure-sensing circuit and pressure-sensing component can be used to measure water depth. When the user is underwater, water pressure can also cause the pressure-sensing component to deform, allowing the pressure-sensing circuit to detect the degree of deformation. The pressure-sensing chip can detect the magnitude of the water pressure based on the electrical signal of the pressure-sensing circuit. Water pressure is proportional to water depth. Through formula calculation, the user's real-time underwater depth information can be obtained, enabling the health monitoring module to have underwater depth detection capabilities.

[0023] In one embodiment, the pressure sensing assembly includes a key rod, a portion of a first surface of the key rod being fixed to a side of the circuit board facing away from the housing. A pressure sensing circuit is disposed on another portion of the first surface of the key rod, with the pressure sensing circuit and the circuit board spaced apart. When the housing is subjected to pressure, the key rod deforms, and the pressure sensing circuit detects the deformation of the key rod.

[0024] It is understood that, compared to installing the pressure sensing circuit at other locations on the key rod, installing the pressure sensing circuit on the first surface of the key rod. Part of the first surface of the key rod can be fixed to the side of the circuit board facing away from the housing. The pressure sensing circuit can be closer to the circuit board. When the pressure sensing circuit is electrically connected to the circuit board, the length of the electrical connection structure between the pressure sensing circuit and the circuit board is shorter, and the volume of the electrical connection structure is smaller, which is conducive to the miniaturization of the health monitoring module.

[0025] In addition, the pressure sensing circuit and the circuit board are spaced apart. The space between the pressure sensing circuit and the circuit board can be used to provide space for the key rod to deform, thereby preventing the key rod from squeezing other nearby devices when deforming.

[0026] In one embodiment, a groove is provided on the first surface of the key rod, and the pressure sensing circuit is disposed in the groove.

[0027] It is understood that the first surface of the key stem can be recessed toward the side away from the circuit board to form a groove, with the wall of the groove forming a portion of the first surface of the key stem. The depth of the groove can be set slightly greater than the thickness of the pressure sensing circuit, and the pressure sensing circuit is fixed to the bottom surface of the groove. The pressure sensing circuit can be spaced apart from the circuit board.

[0028] In one embodiment, the key rod includes a first portion and a second portion. The first portion is plate-shaped, and the second portion is rod-shaped. The second portion is located on the side of the first portion facing away from the circuit board, and one end of the second portion is connected to the middle portion of the first portion. The first surface of the key rod is the surface of the first portion facing away from the second portion. When the housing is subjected to pressure, the first portion deforms, and the pressure-sensing circuit is used to detect the deformation of the first portion.

[0029] It is understandable that the button rod is set to a "T"-shaped structure. The two ends of the first part can be fixed to the circuit board. The connection position between the first surface and the circuit board may include a first position P and a second position P (as shown in the figure). The groove can be set between the first position P and the second position P. When the shell is subjected to pressure, the two ends of the first part are subjected to two forces F, and the middle part of the first part is subjected to a force F, which can cause the first part to be deformed more and the resistance of the pressure sensing circuit to change more, which is beneficial to the detection of the pressure applied to the shell by the user. In addition, when the user presses the shell, the shell is not easy to tilt to one side.

[0030] In one embodiment, the health monitoring module further includes a first waterproof member connected to the first portion and covering the pressure sensing circuit. And / or

[0031] The health monitoring module also includes a second waterproof component, which is sleeved on the second part.

[0032] It is understandable that the first waterproof component can be used to achieve waterproof and dustproof properties of the pressure sensing circuit, preventing water vapor or dust from interfering with the operation of the pressure sensing circuit through the gap between the circuit board and the key rod.

[0033] When the health monitoring module is fixed to the middle frame of the electronic device, the middle frame can be provided with a fixing hole, and a portion of the second portion is located within the fixing hole. In this case, the second waterproof member can abut between the second portion and the wall surface of the fixing hole. It can be understood that the provision of the second waterproof member can reduce the risk of external moisture or dust entering the internal space of the electronic device through the gap between the second portion and the fixing hole, thereby interfering with the operation of components (such as the motherboard) within the internal space of the electronic device.

[0034] In one embodiment, the pressure sensing assembly includes a key rod and a supporting steel sheet. The first surface of the key rod is fixed to the side of the circuit board facing away from the housing. The supporting steel sheet is connected to the second surface of the key rod, with the first and second surfaces of the key rod facing each other. The pressure sensing circuit is fixed to the side of the supporting steel sheet facing away from the key rod. When the housing is subjected to pressure and the supporting steel sheet deforms, the pressure sensing circuit is used to detect the deformation of the supporting steel sheet.

[0035] It is understandable that the pressure sensing circuit and the circuit board are set apart. When the pressure sensing circuit fails, the pressure sensing circuit can be repaired separately without affecting the optical heart rate module, making maintenance more convenient.

[0036] In one embodiment, the pressure sensing component further includes an elastic member, which is in contact between the key rod and the supporting steel sheet, and has elasticity.

[0037] It is understandable that by providing an elastic member, the structural tolerances of the key rod and the supporting steel sheet can be absorbed, as well as the assembly tolerances between the key rod and the supporting steel sheet, thereby preventing excessive holding force between the key rod and the supporting steel sheet, which would cause the supporting steel sheet to deform significantly, thereby reducing the pressure sensing accuracy or even causing the pressure sensing detection to fail. In addition, when the health monitoring module is used as a button, the elastic member can act as a buffer when the user presses the health monitoring module, and the elastic member can also improve the feel of use.

[0038] In one embodiment, the pressure sensing component includes a key rod and a supporting steel sheet, a partial area of ​​the first surface of the key rod is fixed to the side of the circuit board facing away from the outer shell, the supporting steel sheet is connected to the second surface of the key rod, and the second surface of the key rod and the first surface of the key rod are arranged opposite to each other.

[0039] The pressure sensing circuit includes a first pressure sensing circuit and a second pressure sensing circuit. The first pressure sensing circuit is arranged in another part of the first surface of the key rod. The first pressure sensing circuit and the circuit board are arranged at intervals. The second pressure sensing circuit is fixed on the side of the supporting steel sheet away from the key rod.

[0040] When the housing is subjected to pressure, the key rod is deformed and the supporting steel sheet is deformed, the first pressure sensing circuit is used to detect the deformation of the key rod, and the second pressure sensing circuit is used to detect the deformation of the supporting steel sheet.

[0041] It is understandable that two pressure-sensing circuits, a first pressure-sensing circuit and a second pressure-sensing circuit, are provided, and the first pressure-sensing circuit and the second pressure-sensing circuit are spaced apart. Compared to an embodiment in which only one pressure-sensing circuit is provided, this embodiment provides a plurality of pressure-sensing circuits, thereby achieving higher pressure-sensing detection accuracy, which is beneficial for improving the acquisition of ECG and PPG signals. In addition, when one pressure-sensing circuit fails, the other pressure-sensing circuit can still operate normally, making the pressure-sensing detection function of the health monitoring module more reliable.

[0042] In one embodiment, the housing and the light-transmitting member are integrally formed structural members. And / or,

[0043] The light-transmitting component contacts and is fixedly connected to the housing, the optical heart rate module and the circuit board.

[0044] It is understandable that the connection strength between the housing and the light-transmitting member is relatively good. For example, when the light-transmitting member is formed by curing glue, transparent glue can be poured into the housing through a jig. After the glue cures, the light-transmitting member is directly fixedly connected to the housing to form a shape. In this way, the health monitoring module does not need to set up an additional connection structure between the light-transmitting member and the housing, which simplifies the process flow and helps to reduce the cost of the health monitoring module. In addition, no additional connection structure is required between the housing and the light-transmitting member, and there is no visual step difference between the housing and the light-transmitting member, resulting in a better appearance.

[0045] The light-transmitting member contacts and securely connects the housing, the optical heart rate module, and the circuit board. The light-transmitting member can provide waterproofing for the optical heart rate module.

[0046] In one embodiment, the circuit board is provided with a first through hole and a second through hole spaced apart from each other, both of which connect the accommodation space and the outside, and the light-transmitting member is filled in the accommodation space, the first through hole and the second through hole.

[0047] The optical heart rate module includes a light emitter and a light receiver, which are arranged on the circuit board at intervals. The light emitter is located between the first through hole and the second through hole, or the light receiver is located between the first through hole and the second through hole.

[0048] It is understandable that when the light-transmitting member can be formed by a glue-filling process, one of the first through hole and the second through hole can be used as a glue-filling hole, and the other can be used as a glue-discharging hole.

[0049] Compared with the solution in which both the light emitter and the light receiver are located between the first through hole and the second through hole, the light emitter is located between the first through hole and the second through hole, or the light receiver is located between the first through hole and the second through hole. A larger routing space can be reserved on the right side of the light emitter or the left side of the light receiver. The routing space can be used to arrange signal transmission lines for transmitting signals from the conductive part and the light receiver.

[0050] In one embodiment, the optical heart rate module includes a light emitter and a light receiver, which are fixed on the circuit board at intervals. There are two light-transmitting holes, which are arranged at intervals. The light emitter and the light receiver are respectively arranged corresponding to the two light-transmitting holes.

[0051] The shell includes a frame and a shading portion. The frame is connected to the circuit board and encloses a storage space with the circuit board. The light-transmitting hole is set in the frame. The shading portion is connected to the frame and is located in the storage space. The shading portion is at least partially located between the light emitter and the light receiver, and the shading portion is made of opaque material.

[0052] It can be understood that the shading portion can block the light emitted by the light emitter, reducing the light emitted by the light emitter from being directly transmitted to the light receiver position in the accommodation space, so that the light received by the light receiver comes as much as possible from the light reflected by the user, which can improve the measurement accuracy of the heart rate signal.

[0053] In one embodiment, the optical heart rate module and the housing are spaced apart.

[0054] It is understood that the optical heart rate module and the housing are spaced apart, and the gap between the housing and the optical heart rate module can be used to provide a waterproof structure to protect the optical heart rate module from water and dust. In addition, the gap between the housing and the optical heart rate module can also be used to accommodate assembly errors, preventing the housing and the optical heart rate module from abutting or colliding during assembly, which could damage either.

[0055] In one embodiment, the light-transmitting element further fills the accommodating space and covers the optical heart rate module.

[0056] It is understandable that the light-transmitting component can provide waterproof, dustproof and protective functions for the optical heart rate module.

[0057] In one embodiment, the health monitoring module also includes a conductive part, which is located in the accommodating space and is spaced apart from the optical heart rate module. The conductive part is supported between the conductive part and the circuit board and is electrically connected between the conductive part and the circuit board. The conductive part is elastic.

[0058] It is understandable that the conductive member can be electrically connected between the conductive portion and the circuit board, thereby enabling the electrical signal collected by the conductive portion to be transmitted to the circuit board. The conductive member can be elastic. The conductive member can be held between the conductive portion of the housing and the circuit board, and electrically connect the conductive portion and the circuit board. Compared to conductive structures that do not have elasticity, such as metal traces or flexible circuit boards, the conductive member is elastic and is held between the conductive portion of the housing and the circuit board. The conductive member is not easily displaced, which can improve the reliability of the electrical connection between the conductive member and the conductive portion, and between the conductive member and the circuit board.

[0059] In one embodiment, the conductive member is provided with holes. And / or

[0060] A partial area of ​​the first surface of the conductive element is connected to the circuit board, and another partial area of ​​the first surface of the conductive element is recessed in a direction away from the circuit board and is spaced apart from the circuit board.

[0061] It is understandable that the conductive member may be provided with a hole, so that when the conductive member is held between the conductive portion of the housing and the circuit board, the hole may provide a space for deformation.

[0062] A first space is formed between another portion of the first surface and the circuit board. When the conductive member is held between the conductive portion of the housing and the circuit board, the first space can provide a space for deformation.

[0063] In one embodiment, the health monitoring module further includes a conductive layer disposed on the top surface of the housing, the conductive layer being electrically connected to the conductive part, and the hardness of the material used in the conductive layer is greater than the hardness of the material used in the conductive part.

[0064] It is understandable that the conductive layer can be used to prevent the top surface of the housing from being scratched, corroded, abraded, or other adverse factors that may affect the collection of user electrical signals.

[0065] In one embodiment, the health monitoring module further includes a flexible circuit board, which is connected to the circuit board and electrically connected to the circuit board, and the flexible circuit board is located outside the accommodating space.

[0066] It is understood that flexible printed circuit boards can be used to transmit electrical signals on the circuit board. Flexible printed circuit boards have good bendability and can be applied to a wide range of electrical connection scenarios.

[0067] In a second aspect, an embodiment of the present application provides an electronic device, which includes a housing and a health monitoring module, wherein the health monitoring module is mounted in the housing.

[0068] It is understandable that when the health monitoring module is installed on an electronic device, it is conducive to the miniaturization of the electronic device. The housing and the optical heart rate module can be stacked in the thickness direction (Z-axis direction) of the health monitoring module. The health monitoring module can occupy a smaller surface area of ​​the electronic device, which is conducive to saving stacking space of the entire device. More other functional components can be set on the surface of the electronic device to meet the diverse needs of users.

[0069] In one embodiment, the electronic device further includes an ECG chip, which is located inside the housing and electrically connected to the conductive portion of the housing of the health monitoring module.

[0070] It is understandable that the ECG chip can be used to process the electrical signal obtained by the shell to obtain the user's electrocardiogram waveform.

[0071] In one embodiment, the electronic device further includes a screen, the shell includes a middle frame and a back cover, the middle frame is connected between the screen and the back cover, and the health monitoring module is installed in the middle frame and exposed on the outer surface of the middle frame.

[0072] It is understood that the outer surface of the middle frame refers to the surface of the middle frame away from the internal space of the electronic device, that is, the side of the electronic device. The health monitoring module is installed on the side of the electronic device, which is convenient for the user to touch or press. Compared with the solution of installing the health monitoring module on the screen, installing the health monitoring module on the side of the electronic device does not need to occupy the display area of ​​the screen, which is conducive to increasing the display area of ​​the electronic device.

[0073] In one embodiment, the electronic device is a watch or a bracelet, and the health monitoring module is a button of the watch or the bracelet.

[0074] It is understandable that by integrating the health monitoring function and button function of the electronic device into the health monitoring module, the electronic device can save space for additional button settings, which is conducive to the miniaturization of the electronic device.

[0075] In one embodiment, the electronic device further includes a motor, which is mounted on the housing and vibrates according to data monitored by the health monitoring module.

[0076] It is understood that when the health monitoring module is used as a touch button of an electronic device, the motor can vibrate to prompt the user whether the key operation is valid. The motor generates a vibration, achieving a function similar to that of a touch button. BRIEF DESCRIPTION OF THE DRAWINGS

[0097] The embodiments of the present invention are described below in conjunction with the accompanying drawings. The embodiments described herein with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, and should not be understood as limiting the present invention.

[0098] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. It should be understood that in the present application, "electrical connection" can be understood as the physical contact and electrical conduction of components; it can also be understood as the form in which different components in the circuit structure are connected through physical lines such as printed circuit board (PCB) copper foil or wires that can transmit electrical signals. "Connection" and "connected" can both refer to a mechanical connection relationship or a physical connection relationship. For example, A is connected to B or A and B are connected to each other, which means that there is a fastening component (such as a screw, bolt, rivet, etc.) between A and B, or A and B are in contact with each other and A and B are difficult to separate.

[0099] Furthermore, the word "fixed" in this article should also be understood in a broad sense. For example, "fixed" can be directly fixed or indirectly fixed through an intermediate medium. Among them, "fixed" means connected to each other and the relative position relationship after connection remains unchanged. The directional terms mentioned in the embodiments of the present application, such as "upper", "lower", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present application, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application.

[0103] FIG1 is a schematic diagram of an electronic device 1000 according to an embodiment of the present application.

[0104] The electronic device 1000 may include but is not limited to wearable devices such as smart watches, sports watches, bracelets, augmented reality (AR) glasses, virtual reality (VR) glasses or headphones. The electronic device 1000 may also be a terminal product such as a mobile phone, a tablet or a home appliance. The electronic device 1000 shown in Figure 1 is described using a smart watch as an example. It should be noted that Figure 1 only schematically shows some components included in the electronic device 1000, and the actual size, actual position and actual structure of these components are not limited by the figure. The following figures also only schematically show some components, and the actual size, actual position and actual structure of these components are also not limited by the following figures. The details will not be repeated below.

[0105] As shown in Figure 1, electronic device 1000 may include a watch body 1001 and a watch strap 1002. Watch strap 1002 is connected to watch body 1001. For example, there may be two watch straps 1002, connected to both ends of watch body 1001. When a user wears electronic device 1000, watch strap 1002 may be used to secure watch body 1001 to the user. In other embodiments, there may be only one watch strap 1002.

[0106] The watch body 1001 may include a health monitoring module 100, a screen 210, and a housing 200. The health monitoring module 100 may be mounted on the housing 200. The health monitoring module 100 may be used to detect a user's health parameters, allowing the user to monitor their health status at any time. For example, the health monitoring module 100 may be used to measure the user's blood pressure and electrocardiogram (ECG) data.

[0107] In some embodiments, the screen 210 can be used to display images, etc. The screen 210 can be a flat screen or a curved screen. The display screen of the screen 210 can be an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, or a liquid crystal display (LCD).

[0108] Exemplarily, the housing 200 may include a middle frame 220 and a back cover 230. The screen 210 and the back cover 230 are spaced apart relative to each other, and the middle frame 220 is connected between the screen 210 and the back cover 230. The screen 210, the middle frame 220 and the back cover 230 together enclose an internal space 1003 of the electronic device 1000. The internal space 1003 of the electronic device 1000 can be used to place components of the electronic device 1000, such as a motherboard, a battery, a speaker, or a microphone. In other embodiments, the middle frame 220 and the back cover 230 may also be an integral structural component. When the user wears the electronic device 1000, the screen 210 is located on the side of the watch body 1001 facing away from the user's wrist skin, and the back cover 230 is located on the side of the watch body 1001 facing the user's wrist skin, and the back cover 230 can contact the user's wrist skin.

[0109] FIG2 is a partial cross-sectional view of an embodiment of the electronic device 1000 shown in FIG1 at section line AA.

[0110] As shown in Figures 1 and 2, the health monitoring module 100 can be set on the side of the electronic device 1000. The side of the electronic device 1000 can surround the front of the electronic device 1000 (the side facing the user when the electronic device 1000 is in normal use). Among them, for an electronic device 1000 with a display screen such as a smart watch or a smart bracelet, the front is the side where the screen 210 is located, and the side of the electronic device 1000 can surround the screen 210. For an electronic device 1000 without a screen 210, the front can be the main user interface of the electronic device 1000, and the side of the electronic device 1000 can surround the main user interface.

[0111] Exemplarily, when the housing 200 includes a middle frame 220 and a back cover 230, the health monitoring module 100 can be installed on the middle frame 220 and exposed relative to the outer surface 2201 of the middle frame 220. The outer surface 2201 of the middle frame 220 refers to the surface of the middle frame 220 away from the internal space 1003 of the electronic device 1000, that is, the side of the electronic device 1000. It can be understood that installing the health monitoring module 100 on the side of the electronic device 1000 is convenient for the user to touch or press. Compared with the solution of installing the health monitoring module 100 on the screen 210, installing the health monitoring module 100 on the side of the electronic device 1000 does not need to occupy the display area of ​​the screen 210, which is conducive to increasing the display area of ​​the electronic device 1000.

[0112] In addition, the health monitoring module 100 can also be electrically connected to circuits within the electronic device 1000. For example, if the electronic device 1000 includes a main board and a sub-board, the health monitoring module 100 can be electrically connected to the main board and / or the sub-board to achieve signal transmission. If the electronic device 1000 includes only a main board, the health monitoring module 100 can be electrically connected to the main board.

[0113] In some embodiments, the electronic device 1000 may further include a processor (not shown), which may be fixed to and electrically connected to the mainboard. The health monitoring module 100 may be electrically connected to the processor. Signals collected by the health monitoring module 100 may be transmitted to the processor via the flexible circuit board 99 and the mainboard.

[0114] In some embodiments, the processor can be configured to comprehensively analyze the health parameters of multiple users detected by the health monitoring module 100 to determine whether the user's current physical condition is healthy. If the analysis results indicate that the user is currently in a sub-healthy state, the processor can also provide adjustment suggestions for the user's lifestyle, work, and eating habits based on the analysis results. In some embodiments, the processor can also be configured to analyze the user's current mental state based on the parameters detected by the health monitoring module 100 to determine whether the user has mental health issues such as depression.

[0115] In some embodiments, when the electronic device 1000 is a watch or a wristband, the health monitoring module 100 can also be a button on the watch or wristband. In this way, the user can operate the watch or wristband by touching or pressing the health monitoring module 10, thereby interacting with the electronic device 1000. It will be appreciated that by integrating the health monitoring function and the button function of the electronic device into the health monitoring module 100, the electronic device 1000 can save space for additional buttons, which is conducive to the miniaturization of the electronic device 1000.

[0116] In some embodiments, the health monitoring module 100 may be a touch button. When implementing the button function, the health monitoring module 100 does not need to move relative to the middle frame 220. The user only needs to touch the health monitoring module 100 to implement the button function.

[0117] In other embodiments, the health monitoring module 100 may also be a key with a travel range. When implementing the key function, the user needs to press the health monitoring module 100 to move the health monitoring module 100 relative to the middle frame 220 to generate a certain displacement to implement the key function.

[0118] For ease of description, the thickness direction of the health monitoring module 100 is defined as the Z axis. The length direction of the health monitoring module 100 is defined as the Y axis. The width direction of the health monitoring module 100 is defined as the X axis. It is understood that the coordinate system setting can be flexibly set according to specific actual needs.

[0119] Figure 3 is a schematic structural diagram of an embodiment of the health monitoring module 100 shown in Figure 1. Figure 4 is an exploded schematic diagram of an embodiment of the health monitoring module 100 shown in Figure 3. Figure 5 is a partial cross-sectional view of another embodiment of the electronic device 1000 shown in Figure 1 at section line AA.

[0120] As shown in Figures 3, 4 and 5, the health monitoring module 100 may include a housing 10, an optical heart rate module 20, a circuit board 30 and a light-transmitting member 40. The housing 10 is fixed to one side of the circuit board 30, and together with the circuit board 30, encloses a receiving space 50. The housing 10 is provided with a light-transmitting hole 11, which connects the receiving space 50 with the outside world. The optical heart rate module 20 is located in the receiving space 50, and the optical heart rate module 20 is fixed to the circuit board 30. The light-transmitting member 40 is fixed to the housing 10 and at least partially fills the light-transmitting hole 11. The housing 10, the optical heart rate module 20, the circuit board 30 and the light-transmitting member 40 will be described in detail below with reference to the accompanying drawings.

[0121] Exemplarily, the housing 10 may include a conductive part 1, the conductive part 1 is made of conductive material, a portion of the conductive part 1 is exposed on the top surface 12 of the housing 10, and the other portion is electrically connected to the circuit board 30. The top surface 12 of the housing 10 is the side surface of the housing 10 away from the circuit board 30. When the health monitoring module 100 is installed on the middle frame 220, the top surface 12 of the housing 10 can be exposed on the middle frame 220 (as shown in Figure 5), and a portion of the conductive part 1 is exposed on the top surface 12 of the housing 10. The finger can be touched to the top surface 12 of the housing 10 and electrically connected to the conductive part 1, so that the housing 10 can collect the user's electrical signals.

[0122] For example, when a user wears electronic device 1000, the top surface 12 of housing 10 of health monitoring module 100 is exposed. To measure an electrocardiogram (ECG), the user can place a finger on top surface 12 of housing 10, electrically connecting it to conductive portion 1. This allows housing 10 to collect the user's electrical signal. After processing, the signal can produce an electrocardiogram (ECG) waveform. This waveform can reflect the user's cardiac function.

[0123] In some embodiments, the housing 10 can also be used to sense or detect a user's touch or press, thereby enabling the health monitoring module 100 to function as a key. For example, when a user touches or presses the conductive portion 1, the conductive portion 1 can collect the user's electrical signal. Based on whether the conductive portion 1 collects the user's electrical signal, it is determined whether the user has touched or pressed the conductive portion.

[0124] In other embodiments, the health monitoring module 100 may also be used to sense the user's touch or press action on the housing through other modules. For example, the optical heart rate module 20 may also be used to sense the user's touch action on the housing.

[0125] FIG6 is an enlarged schematic diagram of an embodiment of the structure shown in FIG5 at position B. FIG.

[0126] As shown in Figures 5 and 6, the housing 10 may include a top plate 13 and a side wall 14 (for ease of understanding, the top plate 13 and the side wall 14 are schematically distinguished by dotted lines in Figures 5 and 6). The top plate 13 includes a first surface 131 and a second surface 132 disposed opposite to each other. The side wall 14 includes a first end surface 141, a second end surface 142, an inner side surface 143, and an outer side surface 144. The first end surface 141 and the second end surface 142 are disposed opposite to each other. The inner side surface 143 is connected between the first end surface 141 and the second end surface 142. The outer side surface 144 is connected between the first end surface 141 and the second end surface 142. The second end surface 142 of the side wall 14 is fixed to the first surface 131 of the top plate 13. It can be understood that the second surface 132 of the top plate 13 constitutes the top surface 12 of the housing 10. The first end surface 141 of the side wall 14 is the bottom surface of the housing 10.

[0127] In other words, as shown in FIG6 , the first surface 131 and the second surface 132 are sequentially arranged from bottom to top along the Z-axis. The outer side surface 144 and the inner side surface 143 are sequentially arranged from left to right along the Y-axis. The first end surface 141 and the second end surface 142 are sequentially arranged from bottom to top along the Z-axis.

[0128] The housing 10 may be provided with a light-transmitting hole 11. For example, the light-transmitting hole 11 may be located in the top plate 13. The light-transmitting hole 11 passes through the first surface 131 and the second surface 132 of the top plate 13.

[0129] In some embodiments, the top plate 13 and the side wall 14 can be an integrally formed structural member. It should be noted that the two components are formed into an integrated structural member through an integral molding process, which means that in the process of forming one of the two components, the component is connected to the other component, and there is no need to connect the two components together through reprocessing (such as bonding, welding, snap connection, screw connection). For example, the top plate 13 and the side wall 14 can be integrally formed through a mold infusion process. In some embodiments, the top plate 13 and the side wall 14 can also be made separately and then fixedly connected by gluing or other methods.

[0130] The conductive portion 1 of the housing 10 can be implemented in a variety of ways. The housing 10 can be used as the conductive portion 1 in its entirety or in part.

[0131] In some embodiments, the shell 10 can serve as the conductive portion 1 as a whole. For example, the shell 10 can be made of metal as a whole. Metal materials can conduct electricity, and the entire shell 10 can conduct electricity. When the user touches the shell 10, any position on the top surface 12 of the shell 10 can be electrically connected to the user. The electrical connection area between the shell 10 and the user is large, and the electrical connection reliability is better. In addition, compared with materials such as plastic, metal materials have better strength and are wear-resistant. The overall strength of the shell 10 is better and the service life is longer. When the shell 10 is made of metal as a whole, it can be processed by a computer numerical control (CNC) machine tool or directly formed by a mold, or it can be prepared separately in multiple parts and finally assembled into a mold. This application does not limit this. In other embodiments, the shell 10 can also be made of other non-metallic conductive materials.

[0132] For example, when the entire housing 10 is made of metal, the housing 10 can be directly fixedly connected to the circuit board 30 by conductive adhesive and electrically connected to the circuit board 30. Alternatively, the housing 10 can be directly fixedly connected to the circuit board 30 by welding and electrically connected to the circuit board 30. It is understood that the conductive adhesive itself has a conductive effect and also has an adhesive function. The conductive adhesive is used to fix the housing 10 to the circuit board 30. The conductive adhesive can also be used for electrical conduction between the housing 10 and the circuit board 30, which can eliminate the need for a separate structure for electrical connection between the housing 10 and the circuit board 30, thereby reducing the volume of the health monitoring module 100.

[0133] In other embodiments, a portion of the top plate 13 of the shell 10 and a portion of the side wall 14 of the shell 10 constitute the conductive part 1. In this case, the conductive part 1 is made of a conductive material, and the other parts of the shell 10 except the conductive part 1 can be made of an insulating material. For example, the conductive part 1 is made of a metal material, and the other parts are made of a ceramic material. The part made of metal material and the part made of ceramic material can be fixed by gluing or the like. Alternatively, the conductive part 1 is made of a metal material, and the other parts are made of a polymer inorganic material. In the process of preparing the shell 10, the conductive part 1 can be prepared first, and the conductive part 1 is used as an insert, and then the shell 10 is formed by an insert injection molding process.

[0134] In other embodiments, the top plate 13 of the housing 10 may constitute the conductive portion 1. The sidewalls 14 of the housing 10 may be made of insulating material.

[0135] As shown in Figure 6, the health monitoring module 100 also includes a conductive layer 70 provided on the top surface 12 of the housing 10. The conductive layer 70 can be electrically connected to the conductive part 1, and the hardness of the material used in the conductive layer 70 can be greater than the hardness of the material used in the conductive part 1. When the user needs to measure the electrocardiogram, the user can touch the conductive layer 70 with a finger. The user's electrical signal can be transmitted to the conductive part 1 through the conductive layer 70. It is understandable that the conductive layer 70 can be used to prevent the top surface 12 of the housing 10 from being scratched, corroded, abraded, and other adverse factors from affecting the collection of the user's electrical signal.

[0136] In some embodiments, the conductive layer 70 can be formed using a physical vapor deposition (PVD) process. This allows the conductive layer 70 to have a higher hardness, higher wear resistance, and higher corrosion resistance. In other embodiments, the conductive layer 70 can also be formed using a diamond-like carbon coating or other techniques to achieve even higher hardness.

[0137] In some embodiments, the conductive layer 70 may be made of chromium or a chromium alloy.

[0138] In other embodiments, when the conductive layer 70 is made of a transparent conductive material such as indium tin oxide (ITO), the conductive layer 70 may also be fixed to a surface of the light-transmitting member 40 that is away from the circuit board 30 .

[0139] As shown in FIG5 , the top surface 12 of the housing 10 may include a curved surface so that when a user touches the housing 10 , the user has a better feel.

[0140] In some embodiments, the height of the housing 10 in the Z-axis direction can be in the range of 1 millimeter (mm) to 3 mm. For example, the height of the housing 10 in the Z-axis direction can be 1 mm, 1.5 mm, 2 mm, 2.8 mm, or 3 mm. In this way, the strength of the housing 10 is improved.

[0141] In some embodiments, the length of the housing 10 in the Y-axis direction may be in the range of 6 mm to 20 mm. For example, the length of the housing 10 in the Y-axis direction may be 6 mm, 8 mm, 14 mm, 18 mm, or 20 mm.

[0142] In some embodiments, the circuit board 30 may be a rigid printed circuit board (PCB) or a flexible printed circuit board (FPC).

[0143] In some embodiments, the health monitoring module 100 may further include a reinforcement plate 39. The reinforcement plate 39 may be connected to a side of the circuit board 30 away from the optical heart rate module 20. The reinforcement plate 39 may be used to reinforce the circuit board 30. For example, the reinforcement plate 39 may be made of a metal material, such as iron or an iron alloy.

[0144] As shown in FIG5 , the optical heart rate module 20 can be fixed to the circuit board 30 and electrically connected to the circuit board 30. For example, the optical heart rate module 20 can include a light emitter 21 and a light receiver 22. The light emitter 21 and the light receiver 22 are spaced apart on the circuit board 30. The light emitter 21 can be used to emit light. The light receiver 22 is used to receive light and convert the optical signal into an electrical signal. It will be understood that the light emitter 21 and the light receiver 22 shown in FIG5 are merely schematic representations. In other embodiments, the positions of the light emitter 21 and the light receiver 22 can also be interchanged.

[0145] In some embodiments, the circuit board 30 can be used to electrically connect to a mainboard (not shown). When the conductive portion 1 of the housing 10 collects an electrical signal from the user, the signal can be transmitted to the mainboard via the circuit board 30. For example, the health monitoring module 100 can also include a flexible circuit board 99, which can be used to transmit the signal from the circuit board 30 to the mainboard. This will be described in detail below.

[0146] As shown in Figures 5 and 6, the housing 10 can be fixed to one side of the circuit board 30. The housing 10 and the circuit board 30 together enclose a storage space 50. The light-transmitting hole 11 connects the storage space 50 with the outside world. For example, the first end surface 141 of the side wall 14 is fixed to the circuit board 30. The inner side surface 143 of the side wall 14 can, together with the first surface 131 of the top plate 13 and the circuit board 30, enclose the storage space 50. The light-transmitting hole 11 can pass through the first surface 131 and the second surface 132 of the top plate 13. In this way, the light-transmitting hole 11 can connect the storage space 50 with the outside world.

[0147] In some embodiments, the first end surface 141 of the side wall 14 may be glued and fixed to the circuit board 30 by means of a waterproof adhesive 18 .

[0148] As shown in Figures 4 and 5, the waterproof adhesive can be annular. When the housing 10 is fixed to the circuit board 30 via the waterproof adhesive 18, the waterproof adhesive 18 can seal the accommodating space 50. Furthermore, when the health monitoring module 100 is located in a humid environment or underwater, the waterproof adhesive 18 can prevent moisture from entering the accommodating space 50 through the gap between the housing 10 and the circuit board 30, thereby providing waterproof protection for the components (e.g., the optical heart rate module 20) within the accommodating space 50.

[0149] In other embodiments, the first end surface 141 of the side wall 14 may also be fixed to the circuit board 30 by welding.

[0150] As shown in Figure 5, the optical heart rate module 20 is located in the accommodating space 50. The optical heart rate module 20 and the light-transmitting hole 11 are arranged opposite to each other. The optical heart rate module 20 can emit and receive light through the light-transmitting hole 11. The optical heart rate module 20 can be used to collect the user's photoplethysmography (PPG) signal. For example, the light emitter 21 and the light receiver 22 can be located in the accommodating space 50. The light emitter 21 can be arranged opposite to the light-transmitting hole 11. The light receiver 22 can be arranged opposite to the light-transmitting hole 11. When the user's finger presses the housing 10, the user's finger can cover the light-transmitting hole 11, and the light emitted by the light emitter 21 can be irradiated onto the user's finger through the light-transmitting hole 11. The light can then be reflected or scattered by the blood vessels in the user's finger, return to the accommodating space 50 through the light-transmitting hole 11, be received by the light receiver 22, and form an electrical signal after photoelectric conversion, which is transmitted to the circuit board 30.

[0151] For example, light reflected or scattered by the blood vessels in the user's finger can reflect the user's blood flow information. Blood flow generally refers to the flow of blood in the blood vessels in the body. It is a basic parameter of the blood circulation system, reflecting the process of blood flowing through arteries, capillaries and veins under the action of the heart pumping blood. Blood flow can be characterized by a variety of parameters, including but not limited to speed, flow, direction, stability (whether the flow of blood in the circulatory system is stable), resistance (blood flow is affected by the resistance of the blood vessel wall), pulsatility (fluctuation of blood flow during heart beating), distribution (distribution of blood flow in the body), etc. By measuring and analyzing this blood flow information, the function of the heart and vascular system can be evaluated, cardiovascular disease can be diagnosed, and effective treatment plans can be formulated.

[0152] Blood flow information is interrelated and mutually influential with other physiological characteristics such as heart rate, blood oxygen, and respiration. In physiological characteristic detection, comprehensive consideration of this information helps to more accurately understand the body's physiological state and health status.

[0153] In some embodiments, the number of light-transmitting holes 11 may be two, and the two light-transmitting holes 11 are arranged at intervals, and the light emitter 21 and the light receiver 22 are respectively arranged corresponding to the two light-transmitting holes 11. Exemplarily, for ease of description, the two light-transmitting holes 11 are respectively a first light-transmitting hole 111 and a second light-transmitting hole 112. The first light-transmitting hole 111 and the second light-transmitting hole 112 are arranged at intervals. The first light-transmitting hole 111 and the light-transmitting hole 112 are arranged opposite to each other, and the second light-transmitting hole 112 and the light receiver 22 are arranged opposite to each other. A portion of the light-transmitting member 40 is filled in the first light-transmitting hole 111, and a portion is filled in the second light-transmitting hole 112. The light emitter 21 emits light through the first light-transmitting hole 111 and the light-transmitting member 40. The light receiver 22 receives light through the second light-transmitting hole 112 and the light-transmitting member 40. In other embodiments, the number of light-transmitting hole 11 may also be one.

[0154] FIG. 7 is a partial structural diagram of an embodiment of the structure shown in FIG. 5 .

[0155] As shown in Figures 5 and 7, the optical heart rate module 20 can be spaced apart from the housing 10. Exemplarily, the light emitter 21 may include a top surface 211, a bottom surface 212 and a side surface 213. The top surface 211 of the light emitter 21 and the bottom surface 212 of the light emitter 21 are arranged back to back. The side surface 213 of the light emitter 21 is connected between the top surface 211 of the light emitter 21 and the bottom surface 212 of the light emitter 21. The bottom surface 212 of the light emitter 21 is connected to the circuit board 30. The top surface 211 of the light emitter 21 faces the light-transmitting hole 11. The positional relationship between the light receiver 22 and the housing 10 can refer to the light emitter 21 and will not be repeated here.

[0156] It is understood that the optical heart rate module 20 and the housing 10 are spaced apart, and the gap between the housing 10 and the optical heart rate module 20 can be used to provide a waterproof structure to protect the optical heart rate module 20 from water and dust. In addition, the gap between the housing 10 and the optical heart rate module 20 can also be used to accommodate assembly errors, preventing the housing 10 and the optical heart rate module 20 from abutting or colliding during assembly, which could damage either.

[0157] In other embodiments, the optical heart rate module 20 may also be connected to the housing 10 . For example, the side surface 213 of the light emitter 21 may be connected to the housing 10 .

[0158] In some embodiments, the light emitter 21 can be positioned relative to a portion of the housing 10 in the Z-axis direction. That is, along the thickness direction of the health monitoring module 100, the projection of the light emitter 21 on the circuit board 30 can partially overlap with the projection of the housing 10 on the circuit board 30. The light emitter 21 does not need to be positioned directly opposite the light transmission hole 11. It is understood that the light source of the light emitter 21 can be located to one side of the light emitter 21, rather than directly in the center of the light emitter 21. By staggering the center of the light emitter 21 and the center of the light transmission hole 11, the light source of the light emitter 21 can be positioned relative to the center of the light transmission hole 11, allowing light emitted by the light source to pass through the light transmission hole 11 as much as possible and illuminate the user's skin or tissue. In other embodiments, the light source of the light emitter 21 can also be located at the center of the light emitter 21. Those skilled in the art can design the relative positional relationship between the light emitter 21, the light transmission hole 11, and the housing 10 based on the specific position of the light source of the light emitter 21 on the light emitter 21, so that light emitted by the light source passes through the light transmission hole 11 as much as possible and illuminates the user's skin.

[0159] Illustratively, the light emitter 21 may include one light source or multiple light sources. When the light emitter 21 includes multiple light sources, the wavelengths of light emitted by these light sources may be different from each other, or in other words, the wavelengths of these light sources are different from each other. Illustratively, the wavelengths of the multiple light sources may include near-infrared light bands, red light bands, blue light bands, yellow light bands, green light bands, etc.

[0160] In some embodiments, the height of the housing 10 in the Z-axis direction can be in the range of 1 mm to 3 mm. When the light emitter 21 emits light, the height of the housing 10 is relatively high, which can provide a certain travel distance for the light emitted by the light emitter 21, so that the light can illuminate a larger area of ​​the user's skin surface.

[0161] In some embodiments, the housing 10 may further include a light shield 15 (for ease of understanding, dashed lines schematically distinguish the top plate 13, sidewalls 14, and light shield 15 in FIG5 ). The light shield 15 may be connected to the first surface 131 of the top plate 13 and located in the receiving space 50. The light shield 15 is at least partially located between the light emitter 21 and the light receiver 22. The light shield 15 is made of an opaque material. This shield 15 can block light emitted by the light emitter 21, reducing the amount of light emitted by the light emitter 21 that directly propagates within the receiving space 50 to the light receiver 22. This ensures that the light received by the light receiver 22 is, as much as possible, entirely from light reflected by the user, thereby improving the measurement accuracy of the PPG signal. The top plate 13 and sidewalls 14 may form the frame 19 of the housing 10. The frame 19 may be connected to the circuit board 30 and, together with the circuit board 30, enclose the receiving space 50.

[0162] In some embodiments, the light shielding portion 15 can be an integrally formed structure with the top plate 13. For example, the light shielding portion 15 can be integrally formed with the top plate 13 and the side wall 14 by CNC or mold processing.

[0163] In some embodiments, the light shielding portion 15 can be spaced apart from the circuit board 30. For example, in the Z-axis direction, the spacing between the light shielding portion 15 and the circuit board 30 can be in the range of 0.2 mm to 0.6 mm. For example, in the Z-axis direction, the spacing between the light shielding portion 15 and the circuit board 30 can be 0.2 mm, 0.3 mm, or 0.6 mm. In this way, the gap between the light shielding portion 15 and the circuit board 30 is smaller, and the light shielding portion 15 has a better light-blocking effect.

[0164] In other embodiments, the light shielding portion 15 may also be connected to the circuit board 30. The light shielding portion 15 divides the accommodating space 50 into two independent spaces.

[0165] As shown in Figures 5 and 7 , the light-transmitting member 40 can be fixed to the housing 10 and at least partially fill the light-transmitting hole 11. It is understood that the light-transmitting member 40 is used to seal the light-transmitting hole 11, thereby preventing foreign matter such as dust from entering the accommodation space 50 through the light-transmitting hole 11 and interfering with the operation of the optical heart rate module 20.

[0166] Exemplarily, the light-transmitting member 40 can be formed by curing waterproof glue. In this way, the housing 10, the circuit board 30 and the light-transmitting member 40 can cooperate to provide waterproof protection for the optical heart rate module 20, preventing external impurities such as water vapor from entering the accommodating space 50 through the light-transmitting hole 11 and interfering with the operation of the optical heart rate module 20. There is no need to set up an additional waterproof structure for the optical heart rate module 20, which is conducive to the miniaturization of the health monitoring module 100. The overall waterproof function of the health monitoring module 100 is better. In some embodiments, when the health monitoring module 100 is a stand-alone product, it can achieve a waterproof level of 5ATM, meeting the user's needs for using the electronic device 1000 in an environment with high humidity.

[0167] In some embodiments, the top surface of the light-transmitting member 40 is a curved surface. The top surface of the light-transmitting member 40 is the surface of the light-transmitting member 40 that is away from the circuit board 30. When the light-transmitting member 40 is exposed from the housing 10, the height difference between the top surface of the light-transmitting member 40 and the top surface 12 of the housing can be set to be relatively small, and the top surface of the light-transmitting member 40 can transition smoothly with the top surface 12 of the housing, providing a good feel when a user touches the housing 10.

[0168] The light-transmitting member 40 is made of a light-transmitting material. For example, the light-transmitting member 40 can be transparent glass or formed by curing transparent glue. In this way, the light-transmitting member 40 does not affect the light emitted by the light emitter 21 from irradiating the user's skin or tissue through the light-transmitting hole 11, nor does it affect the reflected light from passing through the light-transmitting hole 11 and being received by the light receiver 22.

[0169] In some embodiments, the light-transmitting member 40 can be filled in the light-transmitting hole 11 and the accommodating space 50 at the same time. The light-transmitting member 40 contacts and is fixedly connected to the housing 10, the optical heart rate module 20 (including the light receiver 22 and the light emitter 21) and the circuit board 30. Exemplarily, the optical heart rate module 20 (including the light receiver 22 and the light emitter 21) can be spaced apart from the housing 10, and the light-transmitting member 40 can contact and be connected to the top surface 211 and the side surface 213 of the light emitter 21. The light-transmitting member 40 can also contact and be connected to the top surface and the side surface of the light receiver 22. The light-transmitting member 40 can contact and be fixedly connected to the side surface of the circuit board 30 close to the housing 10. In this way, the light-transmitting member 40 can cover the optical heart rate module 20 (including the light receiver 22 and the light emitter 21). The light-transmitting member 40 can play a waterproof role for the optical heart rate module 20.

[0170] In other embodiments, when the side surface 213 of the light emitter 21 is connected to the housing 10 , the light-transmitting member 40 may be connected to the top surface 211 of the light emitter 21 .

[0171] In other embodiments, the light-transmitting member 40 may also fill a portion of the accommodation space 50. The light-transmitting member 40 may contact and be fixedly connected to the housing 10, and the light-transmitting member 40 is spaced apart from the optical heart rate module 20 (including the light receiver 22 and the light emitter 21) and the circuit board 30.

[0172] In other embodiments, the light-transmitting member 40 can be located solely within the light-transmitting aperture 11. This allows the light-transmitting member 40 to achieve waterproof, dustproof, and light-transmitting properties. In this case, the light-transmitting member 40 contacts and is fixedly connected to the housing 10. The light-transmitting member 40 is spaced apart from the circuit board 30 and the optical heart rate module 20 (light receiver 22 and light emitter 21).

[0173] In some embodiments, the housing 10 and the light-transmitting member 40 can be integrally formed structural members. In this way, the connection strength between the housing 10 and the light-transmitting member 40 is better. For example, when the light-transmitting member 40 is formed by curing glue, transparent glue can be poured into the housing 10 through a jig. After the glue is cured, the light-transmitting member 40 is directly fixedly connected to the housing 10 to form. In this way, the health monitoring module 100 does not need to set up an additional connection structure between the light-transmitting member 40 and the housing 10, which simplifies the process flow and helps to reduce the cost of the health monitoring module 100. In addition, the light-transmitting member 40 is formed by the jig glue pouring process, and there is no need to set up an additional connection structure between the housing 10 and the light-transmitting member 40. There is no visual step difference between the housing 10 and the light-transmitting member 40, and the appearance effect is better.

[0174] In some embodiments, the circuit board 30 may be provided with a first through hole 31 and a second through hole 32 spaced apart. The first through hole 31 and the second through hole 32 may both connect the accommodating space 50 to the outside world. The light emitter 21 may be spaced apart from the first through hole 31 and the second through hole 32. The light receiver 22 may be spaced apart from the first through hole 31 and the second through hole 32. When the light-transmitting member 40 is formed using a glue potting process, one of the first through hole 31 and the second through hole 32 may serve as a glue potting hole, and the other may serve as a glue outlet hole.

[0175] In some embodiments, the light-transmitting member 40 may be partially filled in the light-transmitting hole 11 , partially filled in the accommodating space 50 , partially filled in the first through hole 31 , and partially filled in the second through hole 32 .

[0176] Exemplarily, the assembly steps of the health monitoring module 100 may include: first fixing the optical heart rate module 20 to the circuit board 30, and then pre-fixing the housing 10 to the circuit board 30 through the waterproof adhesive 18 to form a receiving space 50. The light-transmitting hole 11 is sealed by a jig on one side of the top surface 12 of the housing 10. The circuit board 30 may be provided with a first through hole 31 and a second through hole 32 spaced apart, and the first through hole 31 and the second through hole 32 both connect the receiving space 50 and the outside world. Glue is poured into the receiving space 50 through the first through hole 31 / the second through hole, and the glue is cured to form a light-transmitting member 40. The light-transmitting member 40 can simultaneously contact and connect the housing 10, the optical heart rate module 20 (including the light receiver 22 and the light emitter 21) and the circuit board 30 to form an integrally formed structural member of the housing 10, the light-transmitting member 40, the optical heart rate module 20 and the circuit board 30. At this time, the light-transmitting member 40 can also be used to strengthen the connection strength between the circuit board 30 and the housing 10.

[0177] It can be understood that the light-transmitting member 40 is formed into an integrally formed structural member with the housing 10 , the optical heart rate module 20 and the circuit board 30 by pouring waterproof glue, and the light-transmitting member 40 can provide better waterproof protection for the optical heart rate module 20 .

[0178] In some embodiments, when the light shielding portion 15 of the housing 10 divides the receiving space 50 into two independent spaces, the light-transmitting member 40 may also include two spaced-apart portions. When the light-transmitting member 40 is assembled with the housing 10 and the circuit board 30 using a jig-based glue-filling process, the two independent cavities of the receiving space 50 can be glue-filled separately.

[0179] In some embodiments, when the health monitoring module 100 is mounted on the side of the electronic device 1000, the width of the health monitoring module 100 (the length of the health monitoring module 100 in the X-axis direction) needs to be set smaller to be suitable for use in thin electronic devices. For example, the first through hole 31, the second through hole 32, the light emitter 21, and the light receiver 22 can be spaced apart along the length direction of the health monitoring module 100. In this way, compared to the solution in which the first through hole 31 and the light emitter 21 are spaced apart along the width direction of the health monitoring module, the first through hole 31, the second through hole 32, the light emitter 21, and the light receiver 22 are spaced apart along the length direction of the health monitoring module 100, which is conducive to reducing the width of the health monitoring module 100.

[0180] For example, as shown in Figures 1 and 7, the flexible circuit board 99 can be connected to the left or right side of the circuit board 30. For example, the flexible circuit board 99 can be connected to the right side of the circuit board 30. Compared to connecting the flexible circuit board 99 to the side of the circuit board 30 close to the screen 210 or the side of the circuit board 30 close to the back cover 230, the solution of this embodiment is conducive to reducing the width of the health monitoring module 100.

[0181] As shown in FIG7 , the light emitter 21 may be located between the first through hole 31 and the second through hole 32, or the light receiver 22 may be located between the first through hole 31 and the second through hole 32. For example, the first through hole 31 may be located on the left side of the light receiver 22, and the second through hole 32 may be located between the light emitter 21 and the light receiver 22.

[0182] It is understood that, compared to the solution in which both the light emitter 21 and the light receiver 22 are located between the first through hole 31 and the second through hole 32, the light emitter 21 is located between the first through hole 31 and the second through hole 32, or the light receiver 22 is located between the first through hole 31 and the second through hole 32. This allows for a larger wiring space to be reserved on the right side of the light emitter 21 or the left side of the light receiver 22. The wiring space can be used to arrange signal transmission lines for transmitting signals from the conductive portion 1 and the light receiver 22 to the flexible circuit board 99. Furthermore, the flexible circuit board 99 can be connected to the left or right side of the circuit board 30.

[0183] In some embodiments, when the circuit board 30 is provided with a first through hole 31 and a second through hole 32, the reinforcing plate 39 may also be provided with a third through hole 391 and a fourth through hole 392 corresponding thereto. The third through hole 391 is disposed opposite and communicates with the first through hole 31. The fourth through hole 392 is disposed opposite and communicates with the second through hole 32. The light-transmitting member 40 may fill the light-transmitting hole 11, the accommodation space 50, the first through hole 31, the second through hole 32, the third through hole 391, and the fourth through hole 392.

[0184] In other embodiments, the light-transmitting member 40 may also be formed by injection molding under low temperature and low pressure conditions. One of the first through hole 31 and the second through hole 32 may be used as an injection hole, and the other may be used as an exit hole.

[0185] In other embodiments, the top surface 12 of the housing 10 is sealed with a jig to seal the light-transmitting hole 11. Transparent glue is then poured into the light-transmitting hole 11 of the housing 10. After the glue cures, the housing 10 and the light-transmitting member 40 are formed into an integral structure. The optical heart rate module 20 is then secured to the circuit board 30, and the housing 10 is then secured to the circuit board 30, thereby completing the assembly of the housing 10, optical heart rate module 20, circuit board 30, and light-transmitting member 40.

[0186] In other embodiments, the light-transmitting member 40 may also be first formed by processing and then fixed to the housing 10 by processes such as gluing, clamping or welding.

[0187] In some embodiments, the hardness of the light-transmitting member 40 can meet a pencil test of 2H or higher. This improves the hardness of the light-transmitting member 40, making the surface of the light-transmitting member 40 away from the circuit board 30 less susceptible to scratches and improving its aesthetics. Furthermore, the light-transmitting member 40 has minimal impact on light. When the light emitter 21 emits light and the light receiver 22 receives light through the light-transmitting member 40, light loss is minimal, resulting in higher measurement accuracy for the optical heart rate module 20.

[0188] In some embodiments, the transmittance of the light-transmitting element 40 can be greater than 90%. In this way, the light-transmitting element 40 has a smaller light-blocking effect. When the light emitter 21 emits light and the light receiver 22 receives light through the light-transmitting element 40, light loss is small, and the measurement accuracy of the optical heart rate module 20 is higher.

[0189] In some embodiments, the material of the light-transmitting member 40 is selected to avoid lipids, alcohols, and ketones. For example, the light-transmitting member 40 can be made of polypropylene. Lipids, alcohols, and ketones have a shorter lifespan when exposed to high temperature, high humidity, and acidic or alkaline sweat. When the material of the light-transmitting member 40 is selected to avoid lipids, alcohols, and ketones, the light-transmitting member 40 can still have a longer lifespan in high temperature, high humidity, and acidic or alkaline sweat environments.

[0190] In some embodiments, the elastic modulus of the light-transmitting member 40 after being immersed in acid or alkali does not change by more than 2% compared to before the immersion. This prevents the light-transmitting member 40 from aging due to long-term exposure to acid or alkali sweat, which can prevent the light-transmitting member 40 from forming a gap with the housing 10, and reduces the probability of external impurities such as moisture or dust entering the accommodation space 50 through the gap between the light-transmitting member 40 and the housing 10.

[0191] In some embodiments, the elastic modulus of the light-transmitting member 40 does not vary by more than 2% between temperatures of -30°C and +30°C. This reduces the risk of aging of the light-transmitting member 40 under extreme temperature conditions and the formation of a gap between the light-transmitting member 40 and the housing 10, further reducing the probability of external impurities such as moisture or dust entering the accommodating space 50 through the gap between the light-transmitting member 40 and the housing 10.

[0192] In some embodiments, the elastic modulus of the light-transmitting element 40 does not change by more than 2% within 5 years. Thus, the light-transmitting element 40 has a longer service life, and the health monitoring module 100 has a longer service life.

[0193] The above describes the structures of several health monitoring modules 100 . The following describes a specific implementation of installing the health monitoring module 100 on an electronic device 1000 , as well as an implementation of signal transmission between the health monitoring module 100 and the mainboard of the electronic device 1000 .

[0194] As shown in Figures 1 and 5 , when the health monitoring module 100 is mounted on the electronic device 1000, the housing 200 may be provided with a mounting hole 2202. The health monitoring module 100 may be electrically connected to a mainboard disposed inside the housing 200 through the mounting hole 2202.

[0195] For example, the flexible circuit board 99 can be located outside the accommodation space 50. The flexible circuit board 99 can be connected to the circuit board 30 and electrically connected to the circuit board 30. For example, when the health monitoring module 100 is installed on the middle frame 220, a portion of the flexible circuit board 99 can be located in the internal space 1003 of the housing 200 for connection to the motherboard, a portion can be located within the mounting hole 2202, and another portion can be located outside the housing 200 for electrical connection to the circuit board 30. The circuit board 30 can be electrically connected to the motherboard through the flexible circuit board 99. For example, when the health monitoring module 100 is installed on the middle frame 220 of the electronic device 1000, the mounting hole 2202 can be located on the middle frame 220.

[0196] As shown in Figures 1 and 4, the flexible circuit board 99 may include an electrical connection portion 991, which can be used to electrically connect to the mainboard. Exemplarily, a plurality of pads may be provided on the electrical connection portion 991, which can be used to electrically connect to the mainboard. When the mainboard is arranged parallel to the screen 210, the electrical connection portion 991 may also be parallel to the screen 210, so that an electrical connection with the mainboard can be achieved. When the mainboard is arranged perpendicular to the direction of the screen 210, the electrical connection portion may also be arranged perpendicular to the direction of the screen 210, so as to achieve an electrical connection with the mainboard. It is understandable that the arrangement of the electrical connection portion can be arranged according to the direction of the mainboard of the electronic device 1000, and this application does not impose any restrictions.

[0197] In some embodiments, the flexible printed circuit board 99 can be electrically connected to the mainboard through a board to board connector (BTB), hotbar welding, or a zero insertion force connector (ZIF).

[0198] In some embodiments, the flexible circuit board 99 and the circuit board 30 may be integrally formed components. For example, the flexible circuit board 99 and the circuit board 30 may be part of an integrally formed rigid-flex board. Alternatively, the flexible circuit board 99 and the circuit board 30 may be part of an integrally formed flexible circuit board. In other embodiments, the flexible circuit board 99 may also be electrically connected to the circuit board 30 by providing an electrical connection structure (e.g., a BTB connector or a ZIF connector).

[0199] Exemplarily, the acquisition path of the user's ECG signal may include: after the conductive part 1 of the housing 10 acquires the user's electrical signal, the electrical signal can be transmitted to the main board of the electronic device 1000 through the conductive part 1, the circuit board 30, and the flexible circuit board 99 in sequence.

[0200] For example, the electronic device 1000 may include an electrocardiography (ECG) chip (not shown). The ECG chip may be located in the interior space of the housing 200. For example, the ECG chip may be fixed to the mainboard and electrically connected to the mainboard. The ECG chip may be electrically connected to the conductive portion 1 of the housing 10 via the mainboard, the flexible circuit board 99, and the circuit board 30. The ECG chip may be used to process the electrical signals obtained by the housing 10 to obtain an electrocardiogram waveform of the user.

[0201] In other embodiments, the electronic device 1000 may further include an ECG chip for processing other types of ECG signals in addition to ECG. The ECG chip may be used to process the electrical signals collected by the conductive part 1 to obtain the user's ECG information.

[0202] For example, the user's heart rate signal collection path may include: light emitted by the light emitter 21 can be irradiated onto the user's finger through the light transmission hole 11. The light can then be reflected or scattered by blood vessels in the user's finger, return to the storage space 50 through the light transmission hole 11, and be received by the light receiver 22. After the light receiver 22 of the optical heart rate module 20 collects the optical signal reflected by the user's tissue, it converts the optical signal into an electrical signal, which is then transmitted to the main board of the electronic device 1000 via the circuit board 30 and the flexible circuit board 99.

[0203] For example, the electronic device 1000 may include a PPG chip (not shown). The PPG chip may be fixed to and electrically connected to the mainboard. The PPG chip may be electrically connected to the optical receiver 22 via the mainboard and the circuit board 30. The PPG chip may be used to process the electrical signals collected by the optical receiver 22 to obtain the user's photoplethysmography (PPG) signal.

[0204] In other embodiments, the electronic device 1000 may further include a heart rate chip for processing heart rate signals processed by methods other than PPG. The heart rate chip may be used to process the electrical signal converted by the optical receiver 22 to obtain the user's heart rate information.

[0205] In some embodiments, the PPG signal can be combined with the aforementioned ECG waveform to obtain more accurate blood pressure and other biometric information related to the human cardiovascular system through an algorithm. For example, the health monitoring module 100 can simultaneously collect the user's ECG waveform and PPG signal, calculate the time difference (PPT) between the two through an algorithm, and then convert the difference using a formula to obtain the user's blood pressure data.

[0206] In some embodiments, the electronic device 1000 may include a seal 98. The seal 98 may be fixedly connected between the flexible printed circuit board 99 and the wall of the mounting hole 2202 and fill the interior of the mounting hole 2202. The seal 98 may be used to seal the gap between the flexible printed circuit board 99 and the mounting hole 2202. This prevents moisture or dust from entering the interior space 1003 of the electronic device 1000 through the mounting hole 2202 and interfering with the operation of components (e.g., a motherboard) within the interior space 1003 of the electronic device 1000.

[0207] In some embodiments, seal 98 can be formed by curing glue. For example, seal 98 can be formed by curing waterproof glue. Thus, when electronic device 1000 is in a humid environment or underwater, seal 98 can be used to waterproof electronic device 1000, preventing moisture from entering the interior of the electronic device through mounting hole 2202. Electronic device 1000 can be waterproof.

[0208] In some embodiments, when the health monitoring module 100 is used as a button of the electronic device 1000, it is possible to determine whether the user is touching the housing 10 based on whether the user's PPG signal is collected. In addition, it is also possible to determine whether the user is touching the housing 10 based on the electrical signal collected on the housing 10.

[0209] It is understandable that the housing 10 of the health monitoring module 100 of the present application can be used to collect the user's electrical signals and obtain ECG signals, and the optical heart rate module 20 can be used to obtain the user's PPG signals. After the ECG signals and PPG signals are processed by corresponding algorithms, multiple physiological indicators such as the user's electrocardiogram, heart rate, and blood pressure can be obtained. In traditional technical solutions, the PPG acquisition device and the ECG acquisition device are set separately, and the user needs to use two fingers to touch the PPG acquisition device and the ECG acquisition device at the same time to complete the acquisition of ECG signals and PPG signals. When the health monitoring module 100 of the present application collects the user's ECG signals and PPG signals, the user only needs to place one finger on the top surface 12 of the housing 10, which is easier to operate.

[0210] The health monitoring module 100 integrates both key functions and health monitoring functions. Compared to solutions that separate key functions and health monitoring functions, the health monitoring module 100 of the present application achieves multi-functionality while being compact. When installed on an electronic device 1000, the health monitoring module 100 facilitates miniaturization of the electronic device 1000.

[0211] Furthermore, the housing 10 and the optical heart rate module 20 can be stacked in the thickness direction (Z-axis direction) of the health monitoring module 100. This allows the health monitoring module 100 to occupy a smaller surface area of ​​the electronic device 1000, saving space for stacking the entire device. This allows for more functional components to be installed on the surface of the electronic device 1000, thereby meeting diverse user needs.

[0212] Furthermore, this application utilizes an ECG waveform combined with a PPG signal to measure a user's blood pressure. Compared to traditional blood pressure monitors, this device eliminates the need for an air pump or airbag, resulting in a smaller footprint. The health monitoring module 100 of this application measures blood pressure with a single click, requiring only the user to place their finger on the housing 10. This streamlined testing process makes it more convenient for users.

[0213] In other embodiments, the health monitoring module 100 may further include a temperature sensor on the top surface 12 of the housing 10. When a user touches the housing 10, the temperature sensor may detect a temperature change at the top surface 12 of the housing 10, thereby determining whether the user has touched the top surface 12 of the housing 10.

[0214] FIG8 is a schematic structural diagram of an embodiment of the conductive member 60 in FIG6 .

[0215] As shown in Figures 5 and 8 , the health monitoring module 100 may further include a conductive member 60. The conductive member 60 may be located within the accommodation space 50. The conductive member 60 may be spaced apart from the optical heart rate module 20 (the light emitter 21 and the light receiver 22). The conductive member 60 may be electrically connected between the conductive portion 1 and the circuit board 30, thereby transmitting the electrical signals collected by the conductive portion 1 to the circuit board 30.

[0216] It can be understood that when the health monitoring module 100 can also include a conductive part 60, the acquisition path of the user's ECG waveform can include: after the conductive part 1 of the shell 10 collects the user's electrical signal, the electrical signal can be transmitted to the main board of the electronic device 1000 through the conductive part 1, the conductive part 60, the circuit board 30, and the flexible circuit board 99 in sequence.

[0217] In some embodiments, the conductive member 60 can be elastic. The conductive member 60 can be positioned between the conductive portion 1 of the housing 10 and the circuit board 30, electrically connecting the conductive portion 1 and the circuit board 30. It is understood that, compared to a conductive structure 64 that is not elastic, such as a metal trace or a flexible circuit board, the elasticity of the conductive member 60 allows the conductive member 60 to be positioned between the conductive portion 1 of the housing 10 and the circuit board 30, making it less likely to shift. This can improve the reliability of the electrical connections between the conductive member 60 and the conductive portion 1, and between the conductive member 60 and the circuit board 30.

[0218] As shown in Figures 6 and 8, the conductive member 60 may include a first surface 61 and a second surface 62 disposed opposite each other. A portion of the first surface 61 abuts the circuit board 30, while another portion of the first surface 61 is recessed away from the circuit board 30 and spaced apart from the circuit board 30. The second surface 62 abuts the conductive portion 1 of the housing 10. Thus, a first space is formed between the other portion of the first surface 61 and the circuit board 30. When the conductive member 60 abuts between the conductive portion 1 of the housing 10 and the circuit board 30, the first space provides room for deformation.

[0219] In some embodiments, the conductive member 60 may be provided with a hole 63. Thus, when the conductive member 60 is positioned between the conductive portion 1 of the housing 10 and the circuit board 30, the hole 63 provides space for deformation. The number of holes 63 may be one or more. FIG. 8 illustrates two holes 63.

[0220] In some embodiments, the conductive member 60 may include a conductive structure 64 and an elastic structure 65. The conductive structure 64 may encase the elastic structure 65. The conductive structure 64 is used to electrically connect the conductive portion 1 and the circuit board 30. The elastic structure 65 is used to provide elasticity. When the conductive member 60 is positioned between the circuit board 30 and the conductive portion 1, the elastic structure 65 is compressed, and the elastic force of the elastic structure 65 causes the conductive structure 64 to recover its deformation. A portion of the conductive structure 64 is positioned between the elastic structure 65 and the circuit board 30, electrically connecting the circuit board 30, while the other portion is positioned between the elastic structure 65 and the conductive portion 1 of the housing 10, electrically connecting the conductive portion 1.

[0221] In some embodiments, the conductive structure 64 may be made of conductive metal materials such as copper, and the elastic structure 65 may be made of elastic materials such as silicone or rubber.

[0222] In other embodiments, the conductive member 60 can also be made entirely of conductive silicone with conductive properties. In this way, the conductive member 60 has the elasticity of silicone and can achieve electrical connection between the circuit board 30 and the conductive part 1.

[0223] In other embodiments, the conductive member 60 may also be a solid structure. The conductive member 60 may be disposed between the light emitter 21 and the light receiver 22. The conductive member 60 may serve as a light shielding structure to block the light emitted by the light emitter 21, thereby preventing the light emitted by the light emitter 21 from interfering with the light receiver 22 receiving external light.

[0224] In other embodiments, the conductive member 60 may also be a conductive spring, a conductive spring, a conductive wire, or the like.

[0225] FIG9 is a partial cross-sectional view of one embodiment of the electronic device 1000 shown in FIG1 at section line CC.

[0226] As shown in Figures 4, 5, and 9, the health monitoring module 100 may further include a pressure sensing circuit 80 and a pressure sensing component 90. The pressure sensing component 90 may be fixed to the side of the circuit board 30 facing away from the housing 10, and the pressure sensing circuit 80 may be fixed to the pressure sensing component 90. When the housing 10 is subjected to pressure, the pressure sensing component 90 may deform, and the pressure sensing circuit 80 may be used to detect the deformation of the pressure sensing component 90.

[0227] Exemplarily, the resistance value of the pressure sensing circuit 80 can change according to the degree of deformation of the pressure sensing component 90. The electronic device 1000 can be provided with a pressure sensing chip (not shown). Exemplarily, the pressure sensing chip can be installed on the mainboard and electrically connected to the mainboard. The pressure sensing chip can be electrically connected to the pressure sensing circuit 80. The electronic device 1000 can provide a current with a fixed voltage value to the pressure sensing circuit 80. When the resistance value of the pressure sensing circuit 80 changes, the current on the pressure sensing circuit 80 will also change accordingly. The pressure sensing chip can judge the strength of the user's pressing on the housing 10 based on the magnitude of the current.

[0228] For example, when a user measures ECG and PPG signals, the user places a finger on the housing 10, and the pressure sensing component 90 may deform to varying degrees depending on the force acting between the user's finger and the housing 10. The pressure sensing circuit 80 may be used to detect the deformation of the pressure sensing component 90. In this way, the force with which the user's finger presses the housing 10 can be determined by the degree of deformation of the pressure sensing component 90 detected by the pressure sensing circuit 80.

[0229] It is understandable that when the user's finger is placed in the wrong position on the housing 10, or when the position of the finger is offset from the ideal detection position, the force applied to the pressure sensing component 90 is small. The pressure sensing chip can determine whether the user's finger is in place based on the force applied to the pressure sensing component 90. During the operation of the pressure sensing circuit 80 and the pressure sensing component 90, a first threshold value can be set. The first threshold value is the minimum force applied to the pressure sensing component 90 when the user's finger is in place. When the pressure sensing chip monitors that the real-time force detected by the pressure sensing component 90 is greater than or equal to the first threshold value, the pressure sensing chip can control the health monitoring module 100 to start collecting the user's ECG and PPG signals simultaneously, calculate the time difference between the two, that is, the pulse wave transmission time (PTT), and then convert it through a series of formulas to finally obtain the user's blood pressure data.

[0230] In some embodiments, when the force between the user's finger and the housing 10 is low, the depth of penetration of the light emitted by the light emitter 21 into the tissue beneath the user's skin is limited, and the user's blood vessels are located at a certain depth from the user's skin surface. Generally, the greater the force applied by the user to the housing 10, the better the fit between the user's finger and the keycap 10, and the deeper the light emitted by the light emitter 21 penetrates the user's skin. Therefore, when the health monitoring module 100 is used to measure PPG signals, a second threshold value can be set. When the force between the user's finger and the housing 10 is greater than or equal to the second threshold value, the light emitted by the light emitter 21 penetrates the user's skin to a greater depth, allowing most of the light to illuminate the location of the user's blood vessels beneath the skin. When the pressure sensing chip detects that the real-time force detected by the pressure sensing component 90 is greater than or equal to the second threshold value, the pressure sensing chip controls the health monitoring module 100 to begin collecting the user's PPG signal, thereby improving the accuracy of the collected PPG signal.

[0231] In addition, when the real-time force detected by the pressure sensing component 90 is greater than or equal to the second threshold value, the pressure sensing chip controls the health monitoring module 100 to start collecting the user's ECG signal, so that the force between the user and the shell 10 is within a larger range, and the electrical connection reliability between the shell 10 and the user is better, so that the collected ECG signal is more accurate.

[0232] Exemplarily, the first threshold values ​​may be equal or unequal.

[0233] In some embodiments, the pressure-sensing circuit 80 and the pressure-sensing component 90 can be used to measure water depth. It can be understood that when a user is underwater, water pressure can also cause the pressure-sensing component 90 to deform, allowing the pressure-sensing circuit 80 to detect the degree of deformation of the pressure-sensing component 90. The pressure-sensing chip can detect the magnitude of the water pressure based on the electrical signal from the pressure-sensing circuit 80. The water pressure is proportional to the water depth. A formula can be used to calculate the user's real-time underwater depth information, enabling the health monitoring module 100 to have underwater depth detection capabilities.

[0234] It can be understood that compared with the traditional technical solution of measuring water depth by setting a depth gauge, the depth gauge requires a hole to transmit water pressure. The health monitoring module 100 of the present application directly transmits water pressure to the pressure sensing component 90 through the shell 10, and obtains the water depth through the formula. On the one hand, the health monitoring module 100 of the present application does not require an additional depth gauge device to achieve water depth measurement, and is smaller in size and more convenient to carry. On the other hand, the water pressure is directly transmitted to the pressure sensing component 90 through the top surface 12 of the shell 10, and no hole is required. The top surface 12 of the shell 10 is an exposed structure, which is easy to clean, and the health monitoring module 100 is not prone to dirt and blockage problems.

[0235] It is understood that the pressure sensor detection accuracy can be customized according to the accuracy requirements and depth range requirements. For example, by increasing the area of ​​the pressure sensor strain gauge, the accuracy and range of pressure detection can be improved.

[0236] For example, the pressure detection accuracy of the health monitoring module 100 can reach 5 grams of force (gF) (equivalent to the pressure at a water depth of 0.15 meters), and the pressure detection range can reach 1500 gF (equivalent to the pressure at a water depth of 50 meters).

[0237] In some embodiments, the electronic device 1000 may further include a motor (not shown). The motor may be mounted in the housing 200. For example, the motor may be disposed within the interior space of the electronic device 1000, and the health monitoring module 100 may be electrically connected to the motor. The motor may be configured to vibrate based on data detected by the health monitoring module 100. Several embodiments of vibrating the motor based on data monitored by the health monitoring module 100 will be described below in detail with reference to the accompanying drawings.

[0238] In some embodiments, when the health monitoring module 100 serves as a touch button of the electronic device 1000 , the motor can vibrate to prompt the user whether the operation of the button is valid.

[0239] In some embodiments, the pressure sensing circuit 80 can be electrically connected to the motor of the electronic device 1000. When the user presses the housing 10 and the pressure sensing circuit 80 detects that the pressure sensing component 90 is deformed, the motor can vibrate. The pressure sensing circuit 80 and the pressure sensing component 90 can cooperate with the motor to realize the virtual key function of the health monitoring module 100. For example, the whole machine algorithm sets a corresponding threshold. When the user presses the housing 10 with a finger, the resistance of the pressure sensing circuit 80 changes, and an electrical signal is generated, which is calculated by the pressure sensing chip inside the whole machine. The pressure sensing chip can be electrically connected to the motor to control the motor to generate a vibration, thereby achieving a function similar to a touch button.

[0240] In some embodiments, the detection results of the pressure sensing circuit 80 can also be used to determine false touches. False touches can include false key presses and false touches detected during health checks. For example, if the pressure sensing circuit 80 detects that the user's pressure on the housing 10 exceeds a threshold, it is determined that the user is pressing the housing 10. If the pressure is less than the threshold, it is determined to be a false touch. It is understood that the threshold value can be adjusted based on actual usage.

[0241] In some embodiments, when the pressure sensing circuit recognizes that the force applied to the pressure sensing component 90 is less than a first threshold value, the pressure sensing circuit controls the motor to vibrate to prompt that the position of the user's finger placed on the housing 10 deviates from the ideal detection position.

[0242] In some embodiments, when the pressure sensing circuit recognizes that the force applied to the pressure sensing component 90 is less than a second threshold value, the pressure sensing circuit controls the motor to vibrate to prompt the user to increase the force, thereby improving the acquisition accuracy of ECG and PPG signals.

[0243] In some embodiments, when the health monitoring module 100 collects the user's health parameters, when the PPG and ECG signal collection is completed, the motor can vibrate to indicate that the detection is complete.

[0244] In some embodiments, the pressure sensing circuit 80 may be fixed to the circuit board 30 by gluing.

[0245] In some embodiments, the pressure sensing circuit 80 can be electrically connected to the circuit board 30. The electrical signal of the pressure sensing circuit 80 can be transmitted to the main board of the electronic device 1000 via the circuit board 30 and the flexible circuit board 99. In this way, when the health monitoring module 100 is installed on the middle frame 220, the middle frame 220 only needs to open a mounting hole 2202 for the flexible circuit board 99 to pass through, and the structure of the middle frame 220 is relatively simple. In other embodiments, the pressure sensing circuit 80 can also be directly electrically connected to the main board of the electronic device 1000, and the electrical signal of the pressure sensing circuit 80 does not pass through the circuit board 30 and the flexible circuit board 99. In this case, another through hole can be opened on the middle frame 220 for the electrical signal of the pressure sensing circuit 80 to pass through.

[0246] In some embodiments, the pressure sensing circuit 80 and the circuit board 30 may be integrally formed components. For example, the pressure sensing circuit 80 and the circuit board 30 may be part of an integrally formed rigid-flex board. Alternatively, the pressure sensing circuit 80 and the circuit board 30 may be part of an integrally formed flexible circuit board.

[0247] In some embodiments, the pressure sensing component 90 may include a button rod 91. The button rod 91 may include a first surface 911 and a second surface 912. The first surface 911 of the button rod 91 and the second surface 912 of the button rod 91 are arranged back to back. A partial area of ​​the first surface 911 of the button rod 91 can be fixed to the side of the circuit board 30 facing away from the housing 10. The pressure sensing circuit 80 can be arranged in another partial area of ​​the first surface 911 of the button rod 91. The pressure sensing circuit 80 and the circuit board 30 are spaced apart. When the housing 10 is subjected to pressure, the button rod 91 is deformed. The pressure sensing circuit 80 can be used to detect the deformation of the button rod 91.

[0248] It is understood that, compared to installing the pressure sensing circuit 80 at other locations on the button rod 91, installing the pressure sensing circuit 80 on the first surface 911 of the button rod 91 is advantageous. A portion of the first surface 911 of the button rod 91 can be fixed to the side of the circuit board 30 facing away from the housing 10. The pressure sensing circuit 80 can be closer to the circuit board 30. When the pressure sensing circuit 80 is electrically connected to the circuit board 30, the length and volume of the electrical connection structure between the pressure sensing circuit 80 and the circuit board 30 are reduced, which facilitates miniaturization of the health monitoring module 100.

[0249] In addition, the pressure sensing circuit 80 is spaced apart from the circuit board 30. The space between the pressure sensing circuit 80 and the circuit board 30 can be used to provide space for the deformation of the key rod 91, thereby preventing the key rod 91 from squeezing other nearby devices when deforming.

[0250] As shown in Figure 9, the button rod 91 may be provided with a stepped surface 913. The stepped surface 913 may be connected to the middle frame 220. The stepped surface 913 is located on the side of the first surface 911 away from the circuit board 30. When the housing 10 is subjected to pressure, the housing 10 will move downward, and the pressure F1 applied by the user to the housing 10 is transmitted to a part of the first surface 911 of the button rod 91 through the housing 10 and the circuit board 30. The stepped surface 913 of the button rod 91 may abut the middle frame 220. The reaction force F2 of the middle frame 220 may act on the stepped surface 913 of the button rod 91, and the direction is opposite to the force of the user pressing the housing 10. In this way, another part of the first surface 911 (that is, the area where the pressure sensing circuit 80 is fixed) may be deformed under the action of F1 and F2, and the pressure sensing circuit 80 may detect the deformation of this part.

[0251] In some embodiments, the first surface 911 of the key rod 91 may be provided with a groove 9111, and the pressure sensing circuit 80 may be disposed within the groove 9111. For example, the first surface 911 of the key rod 91 may be recessed toward a side away from the circuit board 30 to form the groove 9111, with the wall of the groove 9111 forming a portion of the first surface 911 of the key rod 91. The depth of the groove 9111 may be slightly greater than the thickness of the pressure sensing circuit 80, and the pressure sensing circuit 80 is secured to the bottom surface of the groove 9111. In this manner, the pressure sensing circuit 80 can be spaced apart from the circuit board 30.

[0252] In some embodiments, the depth of the groove 9111 is in the range of 0.2 mm to 0.5 mm. For example, the depth of the groove 9111 can be 0.2 mm, 0.3 mm, 0.4 mm, or 0.5 mm.

[0253] In some embodiments, the button stem 91 may include a first portion 914 and a second portion 915 (for ease of understanding, the first portion 914 and the second portion 915 are schematically divided by a dotted line in FIG9 ). The first portion 914 is plate-shaped, and the second portion 915 is rod-shaped. The second portion 915 is located on the side of the first portion 914 facing away from the circuit board 30. One end of the second portion 915 is connected to the middle portion of the first portion 914. The first surface 911 of the button stem 91 is the surface of the first portion 914 facing away from the second portion 915. The pressure sensing circuit 80 may be disposed in another portion of the second surface 9142. In this way, the button stem 91 may be T-shaped. When the housing 10 is subjected to pressure, the first portion 914 may deform, and the pressure sensing circuit 80 is used to detect the deformation of the first portion 914. The second surface 912 of the button stem 91 may be the surface of the second portion 915 facing away from the first portion 914.

[0254] It is understandable that the button rod 91 is set to a "T"-shaped structure. The two ends of the first part 914 can be fixed to the circuit board 30. The connection position between the first surface 911 and the circuit board 30 may include a first position P1 and a second position P2 (as shown in Figure 5). The groove 9111 can be set between the first position P1 and the second position P2. When the housing 10 is subjected to pressure, the two ends of the first part 914 are subjected to two forces F1, and the middle part of the first part 914 is subjected to the force F2, which can cause the first part 914 to be deformed more, and the resistance of the pressure sensing circuit 80 changes more, which is beneficial to the detection of the pressure applied to the housing 10 by the user. In addition, when the user presses the housing 10, the housing 10 is not easy to tilt to one side.

[0255] In other embodiments, the first portion 914 may also be cylindrical. The groove 9111 may be provided in the middle of the first surface 911 .

[0256] As shown in Figure 9, the health monitoring module 100 may further include a first waterproof member 59, which may be connected to the first portion 914 and cover the pressure sensing circuit 80. Thus, the first waterproof member 59 can be used to provide waterproof and dustproof protection for the pressure sensing circuit 80, preventing moisture or dust from interfering with the operation of the pressure sensing circuit 80 through the gap between the circuit board 30 and the key rod 91. For example, the first waterproof member 59 may be formed by curing waterproof adhesive.

[0257] In some embodiments, the first surface 911 of the button rod 91 may have a groove 9111 , and the pressure sensing circuit 80 may be disposed in the groove 9111 . The first waterproof member 59 may fill the groove 9111 , connect to the first portion 914 , and cover the pressure sensing circuit 80 .

[0258] In some embodiments, the Shore hardness of the first waterproof member 59 may be within a range of greater than or equal to 20° and less than or equal to 30°.

[0259] In some embodiments, the material of the first waterproof member 59 is selected to avoid lipids, alcohols, and ketones. In this way, the first waterproof member 59 still has a long service life in high temperature, high humidity, acidic and alkaline sweat environments.

[0260] In some embodiments, the elastic modulus of the first waterproof member 59 after being immersed in acid or alkali solution does not change by more than 2% compared to before the immersion. This can slow down the aging of the first waterproof member 59 when exposed to acid or alkali solution for a long time, and reduce the risk of impurities such as water vapor or dust corroding the pressure sensing circuit 80.

[0261] In some embodiments, the elastic modulus of the first waterproof member 59 at -30°C and +30°C does not vary by more than 2%. This can slow down the aging of the first waterproof member 59 in extreme temperature environments and reduce the risk of corrosion of the pressure sensing circuit 80 by impurities such as moisture or dust.

[0262] In some embodiments, the elastic modulus of the first waterproof member 59 does not change by more than 2% within 5 years. This prolongs the service life of the first waterproof member 59 and reduces the risk of water vapor, dust, or other impurities corroding the pressure sensing circuit 80.

[0263] In some embodiments, the health monitoring module 100 further includes a second waterproof member 58, which is sleeved onto the second portion 915. When the health monitoring module 100 is fixed to the middle frame 220 of the electronic device 1000, the middle frame 220 may be provided with a fixing hole 2203, and a portion of the second portion 915 is located within the fixing hole 2203. In this case, the second waterproof member 58 may abut between the second portion 915 and the wall surface of the fixing hole 2203. It is understood that the provision of the second waterproof member 58 can reduce the risk of external moisture or dust entering the internal space of the electronic device 1000 through the gap between the second portion 915 and the fixing hole 2203, thereby interfering with the operation of components (such as the motherboard) within the internal space of the electronic device 1000.

[0264] In some embodiments, the second waterproof member 58 may be made of elastic materials such as silicone or rubber.

[0265] In some embodiments, the health monitoring module 100 may further include a retaining spring 57. The second portion 915 may be provided with a retaining slot 9151. The retaining slot 9151 may have an opening located on a side of the second portion 915. When the health monitoring module 100 is mounted on the middle frame 220, the opening of the retaining slot 9151 may be located within the interior space 1003 of the electronic device 1000. Part of the retaining spring 57 may be fixed within the retaining slot 9151, while part of the retaining spring 57 may extend out of the retaining slot 9151. In this manner, the retaining spring 57 may prevent the health monitoring module 100 from becoming loose outside the electronic device 1000.

[0266] In other embodiments, the health monitoring module 100 may also include a latch fixed to the second portion 915. When the health monitoring module 100 is mounted on the middle frame 220, the latch may be located in the internal space 1003 of the electronic device 1000, and the length of the latch may be greater than the diameter of the fixing hole 2203. In this way, the latch can also prevent the health monitoring module 100 from loosening toward the outside of the electronic device 1000.

[0267] It is understood that, as shown in Figures 1, 2, and 9, the health monitoring module 100 of the present application can be installed as a standalone product on the housing 200 of the electronic device 1000. During installation of the health monitoring module 100 to the housing 200, the flexible printed circuit board 99 of the health monitoring module 100 can enter the internal space 1003 of the electronic device 1000 through the mounting hole 2202. The housing 200 can be provided with a fixing hole 2203, and the pressure sensing component 90 can be restrained relative to the housing 200 by a second waterproof member 58 and a retaining spring 57. The second waterproof member 58 can be used to prevent external moisture or dust from entering the internal space of the electronic device 1000 through the gap between the second portion 915 and the fixing hole 2203. A sealing member 98 is placed in the mounting hole 2202. The sealing member 98 can be used to seal the gap between the flexible printed circuit board 99 and the mounting hole 2202, preventing moisture or dust from entering the internal space 1003 of the electronic device 1000 through the mounting hole 2202. In this way, the assembly seal between the health monitoring module 100 and the housing 200 is completed. The overall waterproof function of the electronic device 1000 is better. In some embodiments, the electronic device 1000 can achieve a waterproof level of 5ATM.

[0268] In some embodiments, the seal 98 can be formed by applying and curing waterproof glue in the mounting hole 2202. It is understood that, compared to the seal 98 made of an elastic material such as a rubber plug, the waterproof glue is fluid before curing, can fill smaller gaps, can better adapt to the shape of the gap between the mounting hole 2202 and the flexible circuit board 99, and can better seal the gap between the mounting hole 2202 and the flexible circuit board 99.

[0269] A specific implementation of the pressure sensing circuit 80 and the pressure sensing component 90 is introduced above. Several implementations of the pressure sensing circuit 80 and the pressure sensing component 90 are introduced below with reference to the accompanying drawings.

[0270] In some embodiments, the same technical contents as those of the health monitoring module 100 in the above embodiments are not described in detail. Fig. 10 is a partial cross-sectional view of another embodiment of the electronic device 1000 shown in Fig. 1 at section line AA.

[0271] As shown in Figure 10, the button rod 91 may include a fixed portion 916 and a deformable portion 917. The fixed portion 916 may be fixed to the side of the circuit board 30 facing away from the housing 10. One end of the deformable portion 917 is fixed to the fixed portion 916, and the other end of the deformable portion 917 may be connected to the middle frame 220. The pressure sensing circuit 80 is fixed to the deformable portion 917. When the user presses the housing 10, the fixed portion 916 may move downward, the deformable portion 917 is held between the circuit board 30 and the middle frame 220, and the deformable portion 917 is deformed. The pressure sensing circuit 80 may be fixed on the deformable portion 917. The pressure sensing circuit 80 may be used to detect the deformation of the deformable portion 917.

[0272] In some embodiments, when the user presses the housing 10, the deformable portion 917 is held between the circuit board 30 and the middle frame 220. The deformable portion 917 is subjected to a holding force along the thickness direction of the health monitoring module 100 and deforms along the thickness direction.

[0273] In some embodiments, there may be two deformable portions 917, each fixed to the ends of the fixing portion 916. There may also be two pressure sensing circuits 80, each corresponding to one of the two deformable portions 917.

[0274] As shown in FIG10 , the button rod 91 is provided with a first deformable portion 917, a fixed portion 916, and a second deformable portion 917 from left to right along the Y-axis. The circuit board 30, the deformable portion 917, and a portion of the middle frame 220 are arranged in sequence from top to bottom along the Z-axis.

[0275] In some embodiments, the shape of the deformable portion 917 can be a continuous "W" shape, or a continuous "S" shape, "V" shape, etc. The shape of the deformable portion 917 can be designed according to needs and is not limited in this application.

[0276] In some embodiments, the deformation portion 917 may be a leaf spring.

[0277] In other embodiments, the number of the deformation portion 917 may also be one.

[0278] In some embodiments, the same technical contents as those of the health monitoring module 100 in the above embodiments are not described in detail. Fig. 11 is a partial cross-sectional view of another embodiment of the electronic device 1000 shown in Fig. 1 at section line AA.

[0279] As shown in Figure 11, the button stem 91 may include a fixed portion 916 and a deformable portion 917. The fixed portion 916 may include a first portion 9161 and a second portion 9162. The first portion 9161 may be plate-shaped, and the second portion 9162 may be rod-shaped. The first portion 9161 of the fixed portion 916 may be fixed to the side of the circuit board 30 facing away from the housing 10. The second portion 9162 may be located on the side of the first portion 9161 facing away from the circuit board 30, with one end of the second portion 9162 connected to the middle of the first portion 9161. The deformable portion 917 may have a spiral structure and be sleeved onto the second portion 9162. When a user presses the housing 10, the fixed portion 916 may move downward, with one end of the deformable portion 917 abutting the first portion 9161 of the fixed portion 916 and the other end abutting the middle frame 220, causing the deformable portion 917 to deform. The pressure sensing circuit 80 may be used to detect the deformation of the deformable portion 917.

[0280] 11 , the first portion 9161 and the second portion 9162 of the fixing portion 916 are sequentially arranged from top to bottom along the Z-axis. The circuit board 30, the first portion 9161, the deformable portion 917, and part of the middle frame 220 are sequentially arranged from top to bottom along the Z-axis.

[0281] In some embodiments, the deformation portion 917 may be a spring.

[0282] In some embodiments, the same technical content as the health monitoring module 100 in the previous embodiment is not repeated. Figure 12 is a structural diagram of another embodiment of the health monitoring module 100 shown in Figure 1. Figure 13 is an exploded schematic diagram of an embodiment of the health monitoring module 100 shown in Figure 12.

[0283] As shown in Figures 12 and 13, the health monitoring module 100 may include a housing 10, an optical heart rate module 20, a circuit board 30, a light-transmitting member 40, a retaining spring 57, a second waterproof member 58, a conductive member 60, a flexible circuit board 99, a pressure sensing circuit 80, and a pressure sensing assembly 90. The arrangement of the housing 10, the optical heart rate module 20, the circuit board 30, the light-transmitting member 40, the retaining spring 57, the second waterproof member 58, the conductive member 60, and the flexible circuit board 99 may refer to the arrangement of the housing 10, the optical heart rate module 20, the circuit board 30, the light-transmitting member 40, the retaining spring 57, the second waterproof member 58, the conductive member 60, and the flexible circuit board 99 in the previous embodiment, and will not be repeated here.

[0284] Figure 14 is a partial cross-sectional view of another embodiment of the electronic device 1000 shown in Figure 1 at section line AA. Figure 15 is a partial cross-sectional view of another embodiment of the electronic device 1000 shown in Figure 1 at section line CC. It will be understood that Figures 14 and 15 are intended to illustrate the assembly of the health monitoring module 100 shown in Figure 12 on the electronic device 1000.

[0285] As shown in Figures 13 to 15, the pressure sensing component 90 may include a button rod 91 and a supporting steel sheet 92. The button rod 91 may include a first surface 911 and a second surface 912. The first surface 911 of the button rod 91 and the second surface 912 of the button rod 91 are arranged back to back. The first surface 911 of the button rod 91 is fixed to the side of the circuit board 30 facing away from the housing 10. The supporting steel sheet 92 is connected to the second surface 912 of the button rod 91, and the pressure sensing circuit 80 is fixed to the side of the supporting steel sheet 92 away from the button rod 91. When the housing 10 is subjected to pressure, the supporting steel sheet 92 can undergo elastic deformation, and the pressure sensing circuit 80 can be used to detect the deformation of the supporting steel sheet 92.

[0286] It is understandable that the pressure sensing circuit 80 and the circuit board 30 are spaced apart. When the pressure sensing circuit 80 fails, the pressure sensing circuit 80 can be repaired alone without affecting the optical heart rate module 20, making maintenance more convenient.

[0287] In some embodiments, when the health monitoring module 100 is installed in the middle frame 220, a portion of the button rod 91 is located in the internal space of the electronic device 1000, and the other portion is exposed from the middle frame 220. The supporting steel sheet 92 and the pressure sensing circuit 80 can be installed in the internal space of the electronic device 1000. In this way, compared with the embodiment shown above (as shown in Figure 5), the supporting steel sheet 92 and the pressure sensing circuit 80 can be installed in the internal space 1003 of the electronic device 1000. When the electronic device 1000 falls or is hit by a large external force, the middle frame 220 can protect the pressure sensing circuit 80 and the supporting steel sheet 92, and the reliability of the electronic device 1000 is better. In addition, the health monitoring module 100 does not need to set up an additional waterproof structure to waterproof the pressure sensing circuit 80.

[0288] In some embodiments, the support steel sheet 92 may include a main body 921, a first ear 922, and a second ear 923, wherein the first ear 922 and the second ear 923 are respectively connected to the ends of the main body 921. When the health monitoring module 100 is mounted on the middle frame 220, the first ear 922 and the second ear 923 may be fixedly connected to the middle frame 220. For example, the middle frame 220 may include a first protrusion 2208 and a second protrusion 2209. The first ear 922 may be provided with a fifth through hole 9221, and the second ear 923 may be provided with a sixth through hole 9231. When the health monitoring module 100 is mounted on the middle frame 220, the first protrusion 2208 may be partially located within the fifth through hole 9221. The second protrusion 2209 may be partially located within the sixth through hole 9231. Thus, when the housing 10 is subjected to pressure, the button rod 91 moves relative to the fixing hole 2203 toward the interior space of the electronic device 1000. The button rod 91 can abut against the main body 921 of the supporting steel sheet 92, causing the main body 921 to deform under the force. The pressure sensing circuit 80 is used to detect the deformation of the supporting steel sheet 92.

[0289] In some embodiments, the pressure sensing component 90 may further include an elastic member 93, which abuts between the button rod 91 and the supporting steel sheet 92, and the elastic member 93 is elastic. It is understandable that by providing the elastic member 93, the structural tolerances of the button rod 91 and the supporting steel sheet 92 can be absorbed, and the assembly tolerances between the button rod 91 and the supporting steel sheet 92 can also be absorbed, thereby avoiding excessive holding force between the button rod 91 and the supporting steel sheet 92, which causes a large deformation of the supporting steel sheet 92, reduces the pressure sensing detection accuracy or causes the pressure sensing detection to fail. In addition, when the health monitoring module 100 is used as a button, when the user presses the health monitoring module 100, the elastic member 93 can play a buffering role, and the elastic member 93 can also improve the feel of use.

[0290] As shown in FIG. 13 to FIG. 15 , the circuit board 30 , the key rod 91 , the elastic member 93 , a portion of the supporting steel sheet 92 and the pressure sensing circuit 80 are sequentially arranged from top to bottom along the Z-axis direction.

[0291] In some embodiments, the same technical contents as those of the health monitoring module 100 in the previous embodiment are not repeated.

[0292] Fig. 16 is a schematic structural diagram of another embodiment of the health monitoring module 100 shown in Fig. 1. Fig. 17 is an exploded schematic diagram of an embodiment of the health monitoring module 100 shown in Fig. 16.

[0293] As shown in Figures 16 and 17, the health monitoring module 100 may include a housing 10, an optical heart rate module 20, a circuit board 30, a light-transmitting member 40, a retaining spring 57, a second waterproof member 58, a conductive member 60, a flexible circuit board 99, a pressure sensing circuit 80, and a pressure sensing assembly 90. The arrangement of the housing 10, the optical heart rate module 20, the circuit board 30, the light-transmitting member 40, the retaining spring 57, the second waterproof member 58, the conductive member 60, and the flexible circuit board 99 may refer to the arrangement of the housing 10, the optical heart rate module 20, the circuit board 30, the light-transmitting member 40, the retaining spring 57, the second waterproof member 58, the conductive member 60, and the flexible circuit board 99 in the previous embodiment, and will not be repeated here.

[0294] Figure 18 is a partial cross-sectional view of another embodiment of the electronic device 1000 shown in Figure 1 at section line AA. Figure 19 is a partial cross-sectional view of another embodiment of the electronic device 1000 shown in Figure 1 at section line CC. It will be understood that Figures 18 and 19 are intended to illustrate the assembly of the health monitoring module 100 shown in Figure 16 on the electronic device 1000.

[0295] As shown in Figures 17 to 19, the pressure sensing assembly 90 may include a button rod 91, a supporting steel sheet 92, and an elastic member 93. The button rod 91 may include a first surface 911 and a second surface 912. The first surface 911 and the second surface 912 of the button rod 91 are disposed opposite each other. A portion of the first surface 911 of the button rod 91 is fixed to the side of the circuit board 30 facing away from the housing 10, and the supporting steel sheet 92 is connected to the second surface 912 of the button rod 91.

[0296] The pressure sensing circuit 80 may include a first pressure sensing circuit 81 and a second pressure sensing circuit 82. The first pressure sensing circuit 81 is disposed on another portion of the first surface 911 of the key rod 91, spaced apart from the circuit board 30. The second pressure sensing circuit 82 is fixed to the side of the support steel sheet 92 away from the key rod 91. When the housing 10 is subjected to pressure, causing the key rod 91 and the support steel sheet 92 to deform, the first pressure sensing circuit 81 detects the deformation of the key rod 91, and the second pressure sensing circuit 82 detects the deformation of the support steel sheet 92.

[0297] It is understood that two pressure-sensing circuits, a first pressure-sensing circuit 81 and a second pressure-sensing circuit 82, are provided, and the first pressure-sensing circuit 81 and the second pressure-sensing circuit 82 are spaced apart. Compared to an embodiment in which only one pressure-sensing circuit 80 is provided, this embodiment provides a plurality of pressure-sensing circuits 80, thereby achieving higher accuracy in pressure-sensing detection, which is beneficial for improving the acquisition of ECG and PPG signals. In addition, when one of the pressure-sensing circuits 80 fails, the other pressure-sensing circuit 80 can still operate normally, and the pressure-sensing detection function of the health monitoring module 100 is relatively reliable.

[0298] As shown in FIG. 17 to FIG. 19 , the circuit board 30 , the first pressure sensing circuit 81 , the key rod 91 , the elastic member 93 , a portion of the supporting steel sheet 92 and the second pressure sensing circuit 82 are sequentially arranged from top to bottom along the Z-axis direction.

[0299] For example, during pressure testing, the health monitoring module 100 in this embodiment can move relative to the middle frame 220 along the thickness direction of the health monitoring module 100. The force between the second waterproof member 58 and the middle frame 220 causes the first surface 911 of the key rod 91 to deform. In other words, the health monitoring module 100 in this embodiment does not need to have a stepped surface 913 abutting against the middle frame 220.

[0300] The specific arrangement of the button rod 91 and the second pressure sensing circuit 82 and the elastic member 93 can refer to the arrangement of the button rod 91 and the pressure sensing circuit 80 and the elastic member 93 in the embodiment shown in FIG14 , which will not be repeated here.

[0301] For example, when the health monitoring module is installed in the middle frame 220 , the first pressure sensing circuit 81 may be located on the outside of the middle frame 220 , and the second pressure sensing circuit 82 may be located on the inside of the middle frame 220 .

[0302] It can be understood that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other, and any combination of features in different embodiments is also within the scope of protection of the present application. That is to say, the multiple embodiments described above can also be arbitrarily combined according to actual needs.

[0303] It should be understood that all the above drawings are for illustrative purposes only and do not represent the actual size of the product. Moreover, the dimensional ratios between the components in the drawings are not intended to limit the actual product of the present application.

[0304] The above description is merely a specific embodiment of the present application, but the scope of protection of the present 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.
