[0001] This application claims priority to Russian Patent Application No. 2024138905, filed on December 23, 2024, entitled "An Electronic Device with Blood Pressure Measurement Function", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of electronic equipment technology, and more specifically, to an electronic device with blood pressure measurement function. Background Technology

[0003] As living standards continue to improve, people are paying more and more attention to their health. To meet user needs, an increasing number of wearable devices are integrating health measurement functions, such as blood pressure measurement.

[0004] The most common method of blood pressure measurement is the cuff method. However, cuff-based measurement requires an electronic device connected to additional accessories. For example, the electronic device needs to include an air bladder for blood pressure measurement. In this case, the electronic device's structure is relatively bulky. Therefore, how to achieve accurate blood pressure measurement without adding external accessories is a problem that urgently needs to be solved. Summary of the Invention

[0005] This application provides an electronic device with blood pressure measurement function. The electronic device includes a measuring element, a connector, a pressure sensor, a vibrator, and a processor. When a user contacts the measuring element, the vibrator vibrates, the pressure sensor measures the pressure between the user and the measuring element, and the measuring element measures the user's vascular signal. The processor determines the user's blood pressure value based on the pressure value and the vascular signal.

[0006] In a first aspect, an electronic device is provided, comprising: a housing including a mid-frame; a measuring element, at least a portion of which is located outside the mid-frame; a connector, a pressure sensor, and a vibrator, wherein the connector, the pressure sensor, and the vibrator are located within the housing, a first end of the vibrator and the pressure sensor is fixedly connected to the mid-frame, and the connector is fixedly connected to the measuring element, a second end of the pressure sensor, and the vibrator, respectively; and a processor located within the housing, wherein the processor is coupled to the measuring element, the pressure sensor, and the vibrator, respectively.

[0007] According to an embodiment of this application, a vibration signal generated by a vibrator is used to replace the user's heartbeat signal. When the vibrator generates a vibration signal, a measuring device measures the user's vascular signal, and a pressure sensor measures the pressure value between the user and the measuring device (which can be understood as the pressure value exerted on the surface of the measuring device in contact with the user. For example, when the user's finger is in contact with the measuring device, the pressure sensor measures the pressure value exerted on the surface of the measuring device where the user's finger is in contact with the finger). The volume change of the blood vessels can be determined by measuring the user's vascular signal. Therefore, the processor can determine the vascular compliance curve based on the volume change of the blood vessels and the pressure value between the user and the measuring device, thereby obtaining the user's blood pressure value.

[0008] Furthermore, the vibration signal generated by the vibrator can be used to obtain changes in blood vessel volume in a way that substitutes for the user's heartbeat signal, and is roughly the same as the actual changes in blood vessel volume (obtained by the traditional oscilloscope method). Therefore, the electronic device can achieve accurate blood pressure measurement without the need for additional external accessories.

[0009] In conjunction with the first aspect, in some implementations of the first aspect, the electronic device further includes a baffle, and the vibrator is fixedly connected to the middle frame through the baffle; wherein the baffle divides the housing into a first region and a second region, and the connector, the pressure sensor, and the vibrator are located in the first region.

[0010] According to an embodiment of this application, the connector, pressure sensor, and vibrator are located in a first region, while other components (e.g., a processor) may be located in a second region. A baffle may be used to prevent interference between components in the first region and components in the second region.

[0011] In conjunction with the first aspect, in some implementations of the first aspect, the electronic device further includes a spring, and the vibrator is fixedly connected to the baffle via the spring.

[0012] According to the embodiments of this application, the spring can provide a certain elasticity between the baffle and the vibrator, making it easier to design the layout within the electronic device.

[0013] In conjunction with the first aspect, in some implementations of the first aspect, the electronic device further includes a battery located in the second region.

[0014] In conjunction with the first aspect, in some implementations of the first aspect, the electronic device further includes a first limiting member fixedly connected to the housing, and at least a portion of the connecting member is located between the first limiting member and the mid-frame.

[0015] According to an embodiment of this application, the first limiting member can be used to limit the range of movement of the connector when the vibrator vibrates, so that the connector vibrates with the vibrator within a fixed range.

[0016] In conjunction with the first aspect, in some implementations of the first aspect, the middle frame includes a protrusion that serves as the first limiting member.

[0017] According to the embodiments of this application, the first limiting member is a protrusion integrally formed with the middle frame, which is used as an example for explanation. In actual production or design, it can also be other structures. For example, the first limiting member may include a pin fixedly connected to the back cover, etc. The embodiments of this application do not limit this.

[0018] In conjunction with the first aspect, in some implementations of the first aspect, the electronic device further includes a drive member for moving the connector along a first direction, the first direction being the direction from the vibrator to the measuring member.

[0019] According to an embodiment of this application, when a user presses the measuring element, the driving member can move the connecting member along a first direction, thereby adjusting the pressure between the user and the measuring element so that the pressure reaches a threshold in a short time, thus quickly completing the blood pressure measurement. In this case, the user does not need to adjust the pressure applied to the measuring element, resulting in a better user experience during the measurement process.

[0020] In conjunction with the first aspect, in some implementations of the first aspect, the driving element includes a gear and a drive motor, the drive motor being used to rotate the gear, the gear meshing with the connecting element.

[0021] According to the embodiments of this application, the driving component is described as the above structure. In actual production or design, the driving component may also be other structures.

[0022] In conjunction with the first aspect, in some implementations of the first aspect, the electronic device further includes an opening and a second limiting member, a first end of the second limiting member being fixedly connected to the middle frame, and a second end of the second limiting member being movable between a first position and a second position; wherein, when the second end of the second limiting member is located in the first position, the second end of the second limiting member is received within the opening; and when the second end of the second limiting member is located in the second position, the second end of the second limiting member extends out of the opening and forms a receiving cavity with the measuring member.

[0023] According to an embodiment of this application, when a user is measuring blood pressure, the second end of the second limiting member is located in the second position, and the user's finger can be positioned within a receiving cavity formed between the second limiting member and the measuring member. With the user's finger within the receiving cavity, during the process of the driving member adjusting the pressure between the user and the measuring member, the second limiting member can provide support for the user's phone, avoiding measurement inaccuracies caused by the movement of the user's finger, thereby improving the accuracy of blood pressure measurement.

[0024] In conjunction with the first aspect, in some implementations of the first aspect, the electronic device further includes a display screen fixedly connected to the mid-frame, the display screen being used to display the pressure value between the user and the measuring element.

[0025] According to an embodiment of this application, the display screen can be used to display the pressure value between the user and the measuring device. Simultaneously, the display screen can be used to instruct the user to increase the pressure applied to the measuring device until the pressure reaches a threshold. Once the pressure reaches the threshold, the electronic device measures the user's blood pressure. In one embodiment, the display screen can also be used to display the measured blood pressure value.

[0026] The display screen is also used to instruct the user to increase the pressure applied to the measuring element so that the pressure reaches a threshold.

[0027] The electronic device also includes an output device; the output device is used to instruct the user to increase the pressure applied to the measuring element so that the pressure reaches a threshold. The output device can be a speaker or a vibration feedback device. The speaker instructs the user through sound, while the vibration feedback device can be a motor that instructs the user through vibration, such as different vibration amplitudes or frequencies.

[0028] In conjunction with the first aspect, in some implementations of the first aspect, the measuring element includes a vascular signal sensor and a fixing element, wherein the vascular signal sensor and the fixing element are fixedly connected.

[0029] According to an embodiment of this application, the vascular signal sensor can be located outside the middle frame, while the fixing member is located inside the middle frame. The vascular signal sensor is fixedly connected to the connector via the fixing member. When measuring a user's blood pressure, the vascular signal sensor can directly contact the user to acquire the user's vascular signal.

[0030] The vascular signal sensor can be located inside the middle frame, while the fixing member is located outside the middle frame. The fixing member is fixedly connected to the connector via the vascular signal sensor. When measuring a user's blood pressure, the vascular signal sensor acquires the user's vascular signal through the fixing member. In one embodiment, the fixing member is made of a light-transmitting material.

[0031] In conjunction with the first aspect, in some implementations of the first aspect, the vascular signal sensor includes at least one of a photoplethysmography (PPG) sensor and an electrocardiogram (ECG) sensor.

[0032] According to the embodiments of this application, the vascular signal sensor 121 can also be other types of sensors. The embodiments of this application do not limit this, and can be determined according to actual production or design, and will not be described in detail.

[0033] In conjunction with the first aspect, in some implementations of the first aspect, the vibration frequency of the vibrator is greater than or equal to 4Hz.

[0034] According to the embodiments of this application, when the vibration frequency of the vibrator is high, the measurement time for the user can be shortened when acquiring the same number of vascular signal waveforms (one vascular signal waveform can be understood as the vascular signal acquired by the vibrator in one vibration), which is beneficial to improving the user experience. For example, the frequency of a heartbeat is about 1Hz, and the vibration frequency of the vibrator 150 is 15Hz. When acquiring the waveforms of 30 vascular signals, the technical solution provided in this application requires a measurement time of less than 15 seconds, while the traditional oscilloscope method requires a measurement time of 30 seconds.

[0035] Meanwhile, since the vibration frequency of the vibrator is higher than the frequency of the heartbeat, the waveform of the vascular signal generated by the vibrator is less affected by the waveform of the vascular signal generated by the heartbeat, resulting in better measurement accuracy.

[0036] As the vibration frequency of the vibrator increases, the requirements for the measurement sensitivity of the measuring device are further increased. Therefore, the vibration frequency of the vibrator is more practical when it is within a certain range (for example, greater than or equal to 15Hz and less than or equal to 50Hz).

[0037] In conjunction with the first aspect, in some implementations of the first aspect, the electronic device further includes a modem; wherein a first port of the modem is coupled to the measuring element, a second port of the modem is coupled to the pressure sensor, and a third port of the modem is coupled to the processor.

[0038] According to embodiments of this application, a modem can be used to modulate and demodulate signals for processing by a processor. For example, a modem can be used to demodulate vascular signals measured by a measuring device from a user, extracting the envelope signal of the vascular signal curve.

[0039] In conjunction with the first aspect, in some implementations of the first aspect, the electronic device includes a button, the button including the measuring element.

[0040] In a second aspect, an electronic device is provided, comprising: a housing including a mid-frame; a measuring element, at least a portion of which is located outside the mid-frame; a connector, a pressure sensor, and a drive, wherein the connector, the pressure sensor, and the drive are located within the housing, a first end of the pressure sensor is fixedly connected to the mid-frame, the connector is fixedly connected to the second ends of the measuring element and the pressure sensor respectively, and the drive is used to move the connector along a first direction, the first direction being a direction from the connector to the measuring element; and a processor located within the housing, the processor being coupled to the measuring element, the pressure sensor, and the drive.

[0041] In conjunction with the second aspect, in some implementations of the second aspect, the driving element includes a gear and a drive motor, the drive motor being used to rotate the gear, the gear meshing with the connecting element.

[0042] In conjunction with the second aspect, in some implementations of the second aspect, the electronic device further includes an opening and a limiting member, a first end of the limiting member being fixedly connected to the middle frame, and a second end of the limiting member being movable between a first position and a second position; wherein, when the second end of the limiting member is in the first position, the second end of the limiting member is received within the opening; and when the second end of the limiting member is in the second position, the second end of the limiting member extends out of the opening and forms a receiving cavity with the measuring member.

[0057] The following explains the terms that may appear in the embodiments of this application.

[0058] Coupling can be understood as direct coupling and / or indirect coupling. "Coupled connection" can be understood as a direct coupling connection and / or indirect coupling connection. Direct coupling can also be called "electrical connection," which is understood as physical contact and electrical conduction between components; it can also be understood as the form of connection between different components in a circuit structure through physical lines that can transmit signals, such as copper foil or wires on a printed circuit board (PCB). "Indirect coupling" can be understood as two conductors conducting electricity through a gap / non-contact method. In one embodiment, indirect coupling can also be called capacitive coupling, for example, signal transmission is achieved by forming an equivalent capacitance through coupling between the gaps between two conductive components.

[0059] Components / devices: including at least one of lumped components / devices and distributed components / devices.

[0060] Lumped components / devices: This refers to all components whose size is much smaller than the wavelength relative to the circuit's operating frequency.

[0065] In the embodiments of this application, the terms "first," "second," etc., are used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0070] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0071] Figure 1 is a schematic diagram of an electronic device 10 provided in an embodiment of this application.

[0072] As shown in Figure 1, the electronic device 10 can be a wristband or a watch. In one embodiment, the electronic device 10 can also be a mobile terminal such as a mobile phone, and this application embodiment does not limit this.

[0073] In one embodiment, the electronic device 10 may include a watch body 13, a watch strap 20, a watch band 30, and a watch buckle 16.

[0074] The watch body 13 can be rotatably or fixedly connected to the watch strap 20 and watch strap 30 respectively on both sides. The buckle 16 can be located at the end of the watch strap 20 or watch strap 30 away from the watch body 13 (the end not connected to the watch body 13). When the user wears the electronic device 10, the buckle 16 can be used to connect the watch strap 20 and watch strap 30 to each other.

[0075] In one embodiment, the watch body 13 may include components such as a housing and a display screen. In some scenarios, the housing may include a mid-frame and a back cover. The display screen may be located on a first side of the mid-frame and fixedly connected to it. The back cover may be located on a second side of the mid-frame and fixedly connected to it. The first side of the mid-frame can be understood as the side away from the user's wrist when the user wears the electronic device 10. The second side of the mid-frame can be understood as the side closer to (facing) the user's wrist when the user wears the electronic device 10. The housing and the display screen may form a receiving cavity, which can be used to house related components such as circuit boards (not shown in the figure).

[0076] The circuit board and related components may include a printed circuit board (PCB), a processor electrically connected (coupled) to the PCB, and one or more sensors. The processor can be used to control these sensors to perform measurement and detection operations, and the processor can also be used to process the measurement results from the sensors.

[0077] For example, the aforementioned sensor may include one or more of the following: photoplethysmograph (PPG) sensor, pressure sensor, fingerprint sensor, electrocardiogram (ECG) sensor, acceleration (ACC) sensor, ambient light sensor, proximity sensor, touch sensor, temperature sensor, gyroscope sensor, etc.

[0078] Among these, the PPG sensor can be used to measure heart rate, that is, the number of heartbeats a user makes per unit of time. The pressure sensor can be used to measure the pressure between the human body and the electronic device 10. The ECG sensor can be used to measure the bioelectrical signals of the human body. The ACC sensor can be used to measure the magnitude of the acceleration of the electronic device 10 in various directions (generally three axes, namely x, y, and z axes). The value of this acceleration can be used to identify the posture of the electronic device 10 and is used in applications such as pedometers. The gyroscope sensor can be used to determine the motion posture of the electronic device 10. For example, the angular velocity of the electronic device 10 around the three axes (i.e., x, y, and z axes) can be determined by the gyroscope sensor, and these angular velocities can be used to reflect the user's motion state.

[0079] It should be understood that the above description of the sensors in the electronic device 10 is exemplary. In practical applications, the electronic device 10 may also include more or fewer sensors, or other sensors with the same or similar functions may be used to replace the sensors listed above. This application embodiment does not limit the scope of the invention.

[0080] In one embodiment, the cavity enclosed by the housing and the display screen can also be used to house a power supply circuit, which can be used to power electronic components (such as processing units and various sensors) in the electronic device 10. Exemplarily, the power supply circuit may include a battery.

[0081] In one embodiment, the watch strap 20 and watch strap 30 can be rotatably connected to the watch body 13 in various ways, including but not limited to: spring bar interface connection, fixed bar interface connection, hook connection, magnetic connection or threaded connection, etc. For the sake of brevity, they will not be described in detail.

[0082] It should be understood that the above embodiments are described using the example of detachable straps 20 and 30 to the watch body 13. In actual production or design, straps 20 and 30 can be fixedly connected to the watch body 13 (straps 20 and 30 are not detachable from the watch body 13). The connection method between the watch body and strap is not limited in this application embodiment and can be determined according to actual production or design. For the sake of brevity, it will not be elaborated further.

[0083] In one embodiment, the electronic device 10 includes accessories. For example, accessory 40 may include an airbag for blood pressure measurement, accessory 40 may include external electrode pads for electrocardiogram measurement, or accessory 40 may include sensors for measuring ultraviolet intensity, light intensity, etc., and this application does not limit this.

[0084] In one embodiment, accessory 40 may be fixedly connected to watch strap 20 or watch strap 30.

[0085] In one embodiment, the buckle 16 may include one or more of the following: a pin buckle, a folding buckle, a butterfly buckle, or a concealed buckle.

[0086] As living standards continue to improve, people are paying more and more attention to their health. To meet user needs, more and more wearable devices are integrating health measurement functions, such as blood pressure measurement. Common blood pressure measurement methods include cuff-type, for example, in the electronic device 10 shown in Figure 1, users can measure their blood pressure through the blood pressure measuring cuff (accessory 40).

[0087] The oscillometric method commonly used in upper arm cuff blood pressure monitors works on the following principle: the heart generates pressure through contraction and relaxation, which propels blood through the circulatory system; the pressure on the blood vessel walls is blood pressure. The oscillometric method measures blood pressure by recording and analyzing the pressure signal measured in the cuff throughout the process of changing the external pressure of the blood vessel using an air bladder. The following describes an oscillometric method where the air bladder pressure is observed by gradually deflating it after occlusion. As shown in Figure 2, Pe represents the external pressure, i.e., the gas pressure inside the cuff, which can be measured by a pressure sensor. O represents the vascular signal measured in the cuff, which can be obtained by bandpass filtering Pe (typical filtering frequency is 0.2Hz-4Hz). This signal reflects the effect of blood pressure on vasodilation, i.e., the change in blood vessel volume. The amplitude of the vascular signal wave is proportional to the change in blood vessel volume. The greater the volume change per unit pressure, the greater the compliance (volume change per unit pressure). The oscillometric analysis process can be understood as follows: after the pressure generated by the balloon blocks the blood vessel, the external pressure on the blood vessel gradually decreases during the uniform deflation of the balloon. Throughout this process, the pressure exerted by the heart on the artery remains relatively stable. Therefore, the transmural pressure on the arterial wall changes as the external pressure decreases. During this change in transmural pressure, the volume expansion of the blood vessel caused by blood pressure also changes; that is, the amplitude of the vascular signal wave changes with the transmural pressure. The amplitude envelope of the vascular signal wave reflects the change in blood pressure with respect to the blood vessel volume under changing transmural pressure, i.e., the vascular compliance curve. When the compliance curve has its maximum amplitude, the corresponding external pressure can be equivalent to the mean arterial pressure (MAP). The corresponding systolic blood pressure (SBP) and diastolic blood pressure (DBP) are obtained through the compliance curve and corresponding calculations.

[0088] However, the cuff-type measurement method requires electronic equipment 10, including a blood pressure measuring bladder, which results in a relatively bulky structure. Therefore, how to achieve accurate blood pressure measurement without adding external connecting accessories is an urgent problem to be solved.

[0089] It should be understood that during blood pressure measurement, the air bladder generates varying external pressure, causing the blood vessel wall to be simultaneously subjected to internal pressure (an average heartbeat pulse wave of approximately 1 Hz) and external pressure (e.g., air bladder pressure). Under the combined effect of the same heartbeat pulse wave and varying external pressure P, different changes in blood vessel volume (ΔO) will occur. Based on P and ΔO, a compliance curve can be determined, and thus the blood pressure value can be determined. Based on the above principle analysis, using an external vibration signal instead of a heartbeat pulse wave can also determine a compliance curve. Therefore, in the technical solution provided in this application embodiment, a vibration signal is generated by a vibrator, and the volume change of blood vessels under different external pressures is measured using a measuring device to achieve accurate blood pressure measurement.

[0090] This application provides an electronic device with blood pressure measurement function, comprising a measuring element, a connector, a pressure sensor, a vibrator, and a processor. When a user contacts the measuring element, the vibrator vibrates, the pressure sensor measures the pressure value between the user and the measuring element, and the measuring element measures the user's vascular signal. The processor determines the user's blood pressure value based on the pressure value and the vascular signal.

[0091] Figure 3 is a schematic diagram of an electronic device 10 provided in an embodiment of this application.

[0092] It should be understood that, for the sake of brevity, this application embodiment uses a smartwatch as an example for illustration. In actual production or design, the electronic device 10 can also be other types, such as a wristband, tablet computer, mobile phone, etc. This application embodiment does not limit this, and for the sake of brevity, it will not be described in detail.

[0096] It should be understood that "located in the middle frame 111" in the above embodiments can be understood as located outside the space formed by the middle frame 111. For example, it can also be understood as located outside the space formed by the housing 110.

[0097] Connector 130, pressure sensor 140, vibrator 150 and processor 160 are located inside housing 110.

[0098] In one embodiment, the housing 110 may further include a middle frame 111 and a rear cover 112. In one embodiment, the connector 130, pressure sensor 140, vibrator 150, and processor 160 are located within the space formed by the middle frame 111 and the rear cover 112.

The connector 130 is fixedly connected to the measuring element 120. The connector 130 is fixedly connected to the second end of the pressure sensor 140. The connector 130 is fixedly connected to the vibrator 150.

[0100] The processor 160 is coupled to the measuring element 120, the pressure sensor 140, and the vibrator 150, respectively. In one embodiment, the processor 160 can be coupled to the measuring element 120, the pressure sensor 140, and the vibrator 150 via a flexible printed circuit (FPC). In another embodiment, the processor 160 can be integrated with the data acquisition circuitry in the same device (e.g., a processing chip).

[0101] In one embodiment, the electronic device 10 may further include a printed circuit board (PCB) 171. The processor 160 may be located on the PCB 171.

[0102] According to an embodiment of this application, the vibration signal generated by the vibrator 150 replaces the heartbeat signal of the user. As shown in FIG5, when the vibrator generates a vibration signal, the measuring element 120 measures the user's vascular signal, and the pressure sensor 140 measures the pressure value between the user and the measuring element 120 (which can be understood as the pressure value of the surface in contact with the measuring element 120. For example, when the user's finger is in contact with the measuring element 120, the pressure sensor 140 measures the pressure value of the surface in contact with the measuring element 120). As shown in FIG6, the volume change of the blood vessels can be determined by measuring the user's vascular signal by the measuring element 120. Therefore, the processor 160 can determine the compliance curve of the blood vessels by using the volume change of the blood vessels and the pressure value between the user and the measuring element 120, thereby obtaining the user's blood pressure value. For example, the processor 160 can confirm the user's mean arterial pressure, systolic pressure, and diastolic pressure by using the compliance curve.

[0103] As shown in Figure 6, the change in blood vessel volume obtained by using the vibration signal generated by the vibrator 150 to replace the user's heartbeat signal is roughly the same as the actual change in blood vessel volume (the change in blood vessel volume obtained by the conventional oscilloscope method). Therefore, the electronic device 10 achieves accurate blood pressure measurement without the need for additional external connection accessories.

[0104] In one embodiment, the vibration frequency of vibrator 150 is greater than or equal to 4 Hz. In one embodiment, the vibration frequency of vibrator 150 is greater than or equal to 10 Hz. In one embodiment, the vibration frequency of vibrator 150 is greater than or equal to 15 Hz. In one embodiment, the vibration frequency of vibrator 150 is less than or equal to 50 Hz. In one embodiment, the vibration frequency of vibrator 150 is less than or equal to 25 Hz. In one embodiment, the vibration frequency of vibrator 150 is greater than or equal to 15 Hz and less than or equal to 25 Hz.

[0105] It should be understood that when the vibration frequency of the vibrator 150 is relatively high, the measurement time for the user can be shortened when acquiring the same number of vascular signal waveforms (one vascular signal waveform can be understood as the vascular signal acquired by the vibrator 150 in one vibration), which is beneficial to improving the user experience. For example, the frequency of a heartbeat is about 1Hz, and the vibration frequency of the vibrator 150 is 15Hz. When acquiring the waveforms of 30 vascular signals, the technical solution provided in this application embodiment requires a measurement time of less than 15 seconds, while the traditional oscilloscope method requires a measurement time of 30 seconds.

[0106] Meanwhile, since the vibration frequency of the vibrator 150 is higher than the frequency of the heartbeat, the waveform of the vascular signal generated by the vibrator is less affected by the waveform of the vascular signal generated by the heartbeat, resulting in better measurement accuracy.

[0107] As the vibration frequency of the vibrator 150 increases, the requirements for the measurement sensitivity of the measuring element 120 and / or the measurement sensitivity of the pressure sensor 140 are further increased. Therefore, the vibration frequency of the vibrator 150 has good practicality within a certain range (e.g., greater than or equal to 15Hz and less than or equal to 25Hz).

[0108] In one embodiment, the vibration displacement of the vibrator 150 is greater than or equal to 0.05 mm. In another embodiment, the vibration displacement of the vibrator 150 is greater than or equal to 0.1 mm.

[0109] It should be understood that the vibration displacement of vibrator 150 can be interpreted as the amplitude of vibrator 150 during vibration. As the vibration displacement of vibrator 150 increases, the volume change of blood vessels is greater, which is more conducive to the measurement device 120 acquiring blood vessel signals and improving the accuracy of measurement.

[0110] In one embodiment, the electronic device 10 further includes a first limiting member 113. The first limiting member 113 is fixedly connected to the housing 110, and at least a portion of the connector 130 is located between the first limiting member 113 and the middle frame 111.

[0111] It should be understood that the first limiting member 113 can be used to limit the range of movement of the connector 130 when the vibrator 150 vibrates, so that the connector 130 vibrates with the vibrator 150 within a fixed range.

[0112] In one embodiment, the middle frame 111 includes a protrusion. The protrusion serves as a first limiting member 113.

[0113] It should be understood that in the electronic device 10 shown in Figure 4, the first limiting member 113 is a protrusion integrally formed with the middle frame 111 as an example for explanation. In actual production or design, it may be other structures. For example, the first limiting member 113 may include a pin fixedly connected to the back cover 112, etc. The embodiments of this application do not limit this.

[0114] In one embodiment, the pressure sensor 140 is strip-shaped. In another embodiment, the length of the pressure sensor 140 is greater than 8 mm.

[0115] It should be understood that the first and second ends of the pressure sensor 140 are fixedly connected to the middle frame 111 and the connector 130, respectively, forming a lever-like structure. As the length of the pressure sensor 140 increases, under the same pressure (and the same pressure on the connector 130), the deformation of the pressure sensor 140 is greater, and the measurement accuracy of the pressure sensor 140 is higher.

[0116] In one embodiment, the electronic device 10 further includes a nut 140a. The pressure sensor 140 is fixedly connected to the middle frame 111 via the nut 140a.

[0117] It should be understood that the embodiments of this application do not limit the fixing method between the first end of the pressure sensor 140 and the middle frame 111. For the sake of brevity, the embodiments of this application take fixing by nut 140a as an example. In actual production or design, the first end of the pressure sensor 140 and the middle frame 111 can also be fixed by other structures, such as mortise and tenon structure, snap-fit, glue, etc. The embodiments of this application do not limit this.

[0118] In one embodiment, the electronic device 10 further includes a gasket 141. The second end of the pressure sensor 140 is fixedly connected to the connector 130 via the gasket 141.

[0119] It should be understood that the gasket 141 can enhance the strength of the fixed connection between the second end of the pressure sensor 140 and the connector 130, thereby improving the measurement sensitivity of the pressure sensor 140.

[0120] In one embodiment, the electronic device 10 may further include a baffle 151. The connector 130 is fixedly connected to the mid-frame 111 via the baffle 151.

[0121] In one embodiment, baffle 151 divides housing 110 into a first region and a second region. In one embodiment, connector 130, pressure sensor 140, and vibrator 150 are located in the first region. In one embodiment, processor 160 is located in the second region.

[0122] It should be understood that connector 130, pressure sensor 140, and vibrator 150 are located in the first region, while other components (e.g., processor 160) may be located in the second region. Baffle 151 may be used to prevent interference between components in the first region and components in the second region.

[0123] In one embodiment, the electronic device 10 further includes a spring. The vibrator 150 is fixedly connected to the baffle 151 by the spring.

[0124] It should be understood that the spring can provide a certain degree of elasticity between the baffle 151 and the vibrator 150, making it easier to design the layout within the electronic device 10.

[0125] In one embodiment, the electronic device further includes a nut 151a. The baffle 151 is fixedly connected to the middle frame 111 by the nut 151a.

[0126] It should be understood that the embodiments of this application do not limit the fixing method between the baffle 151 and the middle frame 111. For the sake of simplicity, the embodiment of this application takes fixing by nut 151a as an example. In actual production or design, the baffle 151 and the middle frame 111 can also be fixed by other structures, such as mortise and tenon structure, snap-fit, glue, etc. The embodiment of this application does not limit this.

[0127] In one embodiment, the electronic device 10 further includes a battery 170. The battery 170 is coupled to the measuring element 120, the pressure sensor 140, the vibrator 150, and the processor 160 to provide electrical power.

[0128] In one embodiment, battery 170 is located in the aforementioned second region.

[0129] In one embodiment, the measuring element 120 includes a vascular signal sensor 121 and a fixture 122, as shown in FIG7. The vascular signal sensor 121 and the fixture 122 are fixedly connected. The vascular signal sensor 121 is used to acquire the user's vascular signals. The vascular signal sensor 121 is coupled to the processor 160.

[0130] It should be understood that the electronic device 10 may include at least one button, and a corresponding position of one of the buttons is provided with multiple devices for measuring blood pressure as described in the above embodiments. For example, the electronic device 10 may be a smartwatch. A corresponding position of the knob of the smartwatch is provided with multiple devices for measuring blood pressure as described in the above embodiments. Alternatively, the electronic device 10 may be a wristband. A corresponding position of the button of the wristband is provided with multiple devices for measuring blood pressure as described in the above embodiments. Alternatively, the electronic device 10 may be a mobile phone or tablet computer. A corresponding position of the volume button or power button of the mobile phone or tablet computer is provided with multiple devices for measuring blood pressure as described in the above embodiments.

[0131] In one embodiment, the vascular signal sensor 121 may be located outside the middle frame 111, and the fixing member 122 may be located inside the middle frame 111. The vascular signal sensor 121 is fixedly connected to the connector 130 via the fixing member 122. When measuring a user's blood pressure, the vascular signal sensor 121 may be in direct contact with the user to acquire the user's vascular signal.

[0132] In one embodiment, the vascular signal sensor 121 may be located within the middle frame 111, and the fastener 122 may be located outside the middle frame 111. The fastener 122 is fixedly connected to the connector 130 via the vascular signal sensor 121. When measuring a user's blood pressure, the vascular signal sensor 121 acquires the user's vascular signal via the fastener 122. In one embodiment, the fastener 122 is made of a light-transmitting material.

[0133] In one embodiment, the vascular signal sensor 121 includes at least one of a PPG sensor and an ECG sensor.

[0134] It should be understood that the vascular signal sensor 121 can also be other types of sensors. This application embodiment does not limit this and can be determined according to actual production or design, which will not be elaborated in detail.

[0135] In one embodiment, the electronic device 10 may further include a display screen 200, as shown in Figures 8A and 8B. The display screen 200 may be fixedly connected to the mid-frame 111 in the above embodiments.

[0136] It should be understood that the display screen 200 can be used to display the pressure value between the user and the measuring element. Simultaneously, the display screen 200 can be used to instruct the user to increase the pressure applied to the measuring element until the pressure reaches a threshold. When the pressure reaches the threshold, the electronic device 10 measures the user's blood pressure. In one embodiment, the display screen 200 can also be used to display the measured blood pressure value.

[0137] In one embodiment, the electronic device 10 may further include a modem 161, as shown in FIG9. A first port of the modem 161 is coupled to the measuring element 120. A second port of the modem 161 is coupled to the pressure sensor 140. A third port of the modem 161 is coupled to the processor 160.

[0138] It should be understood that modem 161 can be used to modulate and demodulate signals for processing by processor 160. For example, modem 161 can be used to demodulate vascular signals measured by measuring device 120 of a user, extracting the envelope signal of the vascular signal curve.

[0139] In one embodiment, the electronic device 10 may further include a filter 162 and / or a filter 163. In one embodiment, the filter 162 is coupled between a first port of the modem 161 and the measuring element 120. In one embodiment, the filter 163 is coupled between a second port of the modem 161 and the pressure sensor 140.

[0140] It should be understood that filter 162 and / or filter 163 can be bandpass filters, used to allow signals with frequencies within a preset range to pass through, thereby reducing interference from other unwanted signals and facilitating subsequent processing by processor 160.

[0141] Figure 10 is a schematic diagram of an electronic device 10 provided in an embodiment of this application.

[0142] As shown in Figure 10, the electronic device 10 may further include a drive member 180. The drive member 180 is used to move the connector 130 along a first direction, which is the direction from the vibrator 150 to the measuring member 120.

[0143] It should be understood that the electronic device 10 shown in FIG10 differs from the electronic device 10 shown in the above embodiments (FIGs 3, 4, 7 to 9) in that the driving element 180 is different.

[0144] In the above embodiment, the user needs to press the measuring element 120 to make the pressure between the user and the measuring element 120 reach a threshold, thereby measuring the user's blood pressure.

[0145] In the electronic device 10 shown in Figure 10, when the user presses the measuring element 120, the drive element 180 can move the connecting element 130 along a first direction, thereby adjusting the pressure between the user and the measuring element 120 so that the pressure reaches the threshold in a short time, thus quickly completing the blood pressure measurement. In this case, the user does not need to adjust the pressure applied to the measuring element 120, resulting in a better user experience during the measurement process.

[0146] In one embodiment, the vibration displacement of the vibrator 150 is less than or equal to 0.1 mm. In another embodiment, the vibration displacement of the vibrator 150 is less than or equal to 0.05 mm.

[0147] It should be understood that when the electronic device 10 includes a drive element 180, the electronic device 10 can adjust the pressure between the user and the measuring element 120 via the drive element 180. In this case, the vibrator 150 can have a small amount of vibration displacement.

[0148] In one embodiment, the drive member 180 includes a gear 181 and a drive motor 182. The gear 181 meshes with the connector 130. The drive motor 182 drives the gear 181 to rotate, thereby moving the connector 130 along a first direction.

[0149] It should be understood that in this embodiment, the driving component 180 is described using the above structure as an example. In actual production or design, the driving component 180 can also be other structures. For example, the driving component 180 can be a telescopic structure. The first end of the driving component 180 is fixedly connected to the middle frame 111, and the second end is fixedly connected to the connecting component 130. By adjusting the distance between the first end and the second end, the driving component 180 causes the connecting component 130 to move along a first direction, thereby adjusting the pressure between the user and the measuring component 120. This embodiment does not limit this, and for the sake of brevity, it will not be described in detail.

[0150] In one embodiment, the electronic device 10 may further include a second limiting member 190, as shown in Figures 11 and 12. A first end of the second limiting member 190 is fixedly connected to the middle frame 111. A second end of the second limiting member 190 is movable between a first position and a second position.

[0151] The middle frame 111 includes an opening 114. When the second end of the second limiting member 190 is in the first position, the second end of the second limiting member is received within the opening 114, as shown in FIG11.

[0152] When the second end of the second limiting member 190 is in the second position, a receiving cavity is formed between the second limiting member 190 and the measuring member 120, as shown in FIG12.

[0153] It should be understood that when a user is measuring blood pressure, the second end of the second limiting member 190 is in the second position, and the user's finger can be positioned within the receiving cavity formed between the second limiting member 190 and the measuring member 120. With the user's finger within the receiving cavity, during the process of the drive member 180 adjusting the pressure between the user and the measuring member 120, the second limiting member 190 can provide support for the user's finger, preventing measurement inaccuracies caused by finger movement, thereby improving the accuracy of blood pressure measurement.

[0154] In one embodiment, the distance D between the first position and the second position is greater than or equal to 4 mm and less than or equal to 10 mm.

[0155] It should be understood that the distance D between the first position and the second position can also be understood as the displacement of the second end of the second limiting member 190 from the first position to the second position. This distance can also be adjusted according to the size of the designed receiving cavity to accommodate the user's finger size and improve the user experience.

[0156] Figure 13 is a schematic diagram of an electronic device 10 provided in an embodiment of this application.

[0157] As shown in Figure 13, the electronic device 10 includes a housing 110, a measuring element 120, a connector 130, a pressure sensor 140, a drive element 180, and a processor 160.

[0158] The housing 110 includes a middle frame 111.

[0159] At least a portion of the measuring element 120 is located outside the middle frame 111. In one embodiment, when a user is measuring blood pressure, the user's finger contacts the portion of the measuring element 120 located outside the middle frame 111.

[0160] Connector 130, pressure sensor 140, drive 180 and processor 160 are located inside housing 110.

[0161] In one embodiment, the housing 110 may further include a middle frame 111 and a rear cover 112. In one embodiment, the connector 130, pressure sensor 140, actuator 180, and processor 160 are located within the space formed by the middle frame 111 and the rear cover 112.

[0162] The first end of the pressure sensor 140 is fixedly connected to the middle frame 111. The connector 130 is fixedly connected to the measuring element 120. The connector 130 is fixedly connected to the second end of the pressure sensor 140. The drive element 180 is used to move the connector 130 along a first direction, which is the direction from the connector 130 to the measuring element 120.

[0163] The processor 160 is coupled to the measuring element 120, the pressure sensor 140, and the drive element 180, respectively. In one embodiment, the processor 160 can be coupled to the measuring element 120, the pressure sensor 140, and the drive element 180 via an FPC. In another embodiment, the processor 160 can be integrated with the data acquisition circuitry in the same device (e.g., a processing chip).

[0164] In one embodiment, the electronic device 10 may further include a PCB 171. The processor 160 may be located on the PCB 171.

[0165] It should be understood that the electronic device 10 shown in FIG13 differs from the electronic device 10 shown in the above embodiments (FIGs 3, 4, 7 to 9, 10 to 12) in that it does not include the vibrator 150.

[0166] In the electronic device 10 shown in the above embodiments (Figures 3, 4, 7 to 9, 10 to 12), the vibration signal generated by the vibrator 150 replaces the beating signal of the user's heart. When the vibrator generates a vibration signal, the measuring element 120 measures the user's vascular signal, and the pressure sensor 140 measures the pressure value between the user and the measuring element 120. The volume change of the blood vessels can be determined by measuring the user's vascular signal by the measuring element 120. Therefore, the processor 160 can determine the vascular compliance curve by using the volume change of the blood vessels and the pressure value between the user and the measuring element 120, thereby obtaining the user's blood pressure value. For example, the processor 160 can determine the user's mean arterial pressure by using the compliance curve, and then determine the corresponding systolic and diastolic blood pressure based on the mean arterial pressure.

[0167] In the electronic device 10 shown in Figure 13, when the user presses the measuring element 120, the drive element 180 can move the connecting element 130 along a first direction, thereby adjusting the pressure between the user and the measuring element 120. The pressure sensor 140 measures the pressure value between the user and the measuring element 120. The measuring element 120 measures the user's vascular signals at different pressure values. Therefore, the processor 160 can determine the vascular compliance curve based on the vascular volume change and the pressure value between the user and the measuring element 120, thereby obtaining the user's blood pressure value. For example, the processor 160 can determine the user's mean arterial pressure through the compliance curve, and then determine the corresponding systolic and diastolic blood pressure based on the mean arterial pressure.

[0168] In one embodiment, the drive member 180 includes a gear 181 and a drive motor 182. The gear 181 meshes with the connector 130. The drive motor 182 drives the gear 181 to rotate, thereby moving the connector 130 along a first direction.

[0169] It should be understood that in this embodiment, the driving component 180 is described using the above structure as an example. In actual production or design, the driving component 180 can also be other structures. For example, the driving component 180 can be a telescopic structure. The first end of the driving component 180 is fixedly connected to the middle frame 111, and the second end is fixedly connected to the connecting component 130. By adjusting the distance between the first end and the second end, the driving component 180 causes the connecting component 130 to move along a first direction, thereby adjusting the pressure between the user and the measuring component 120. This embodiment does not limit this, and for the sake of brevity, it will not be described in detail.

[0170] In one embodiment, the electronic device 10 may further include a second limiting member 190, as shown in FIG14. A first end of the second limiting member 190 is fixedly connected to the middle frame 111. A second end of the second limiting member 190 is movable between a first position and a second position.

[0171] The middle frame 111 includes an opening 114. When the second end of the second limiting member 190 is in the first position, the second end of the second limiting member is received within the opening 114. When the second end of the second limiting member 190 is in the second position, a receiving cavity is formed between the second limiting member 190 and the measuring member 120.

[0172] It should be understood that when a user is measuring blood pressure, the second end of the second limiting member 190 is in the second position, and the user's finger can be positioned within the receiving cavity formed between the second limiting member 190 and the measuring member 120. With the user's finger within the receiving cavity, during the process of the drive member 180 adjusting the pressure between the user and the measuring member 120, the second limiting member 190 can provide support for the user's finger, preventing measurement inaccuracies caused by finger movement, thereby improving the accuracy of blood pressure measurement.

[0173] For the sake of brevity, the parts of the electronic device 10 shown in Figure 13 that are similar to those in the above embodiments (Figures 3, 4, 7 to 9, 10 to 12) will not be described in detail. These similar parts include: the shape of the pressure sensor 140; the gasket 141 fixedly connected between the second end of the pressure sensor 140 and the connector 130; the baffle 151 fixedly connected between the connector 130 and the middle frame 111; the baffle 151 fixedly connected to the middle frame 111 by a nut; the battery 170 located in the second region; the structure of the measuring element 120, and the type of the vascular signal sensor 121 in the measuring element 120; the display screen 200 for displaying the pressure value between the user and the measuring element or displaying the blood pressure measurement structure; the modem 161 for processing signals; and so on.

[0174] The above description describes specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
