[0002] With the development of device technology, the functions of electronic devices are becoming more and more abundant. For example, wearable electronic devices can measure the user's physiological parameters, such as blood pressure, heart rate, etc.

[0003] For example, taking a blood pressure detection watch as an example, the measurement accuracy of most blood pressure detection watches on the market is relatively average. The reason is that the pressure on the wristband of the watch is insufficient, and it is difficult to effectively compress the blood vessels at the wrist of the local user, resulting in the sensor in the blood pressure detection watch being unable to obtain the user's real parameters, such as the user's pulse signal. Therefore, how to effectively apply pressure to the area on the user's skin surface corresponding to the measurement area of ​​the wearable electronic device is an urgent problem to be solved. Summary of the invention

[0012] In the embodiment of the present application, on the one hand, when the motor reset component is in the first working state, the motor can drive the transmission component to inflate the air cushion, so that when the user wears the wearable device, the air cushion can apply pressure to the user's skin surface to effectively compress the user's blood vessels, thereby ensuring that the measurement component can measure the user's real physiological data.

[0041] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0042] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here. In addition, the "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally represents that the objects associated with each other are in an "or" relationship.

[0043] The wearable device, physiological parameter measurement method and apparatus provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0044] The present application embodiment provides a wearable device 1000, Figure 1 is a possible structural diagram of the wearable device 1000 provided in the embodiment of the present application, such as Figure 1 As shown, the wearable device 1000 may include: a shell 10, a pressure pad 20 arranged on the wearing surface 11 of the shell 10, and a motor reset assembly 30, a motor, a transmission assembly 50 and a measuring assembly 60 arranged in the shell 10; the pressure pad 20 is hollow inside, and the transmission assembly 50 is connected to the air inlet end 23 of the pressure pad; the motor is located between the motor reset assembly 30 and the transmission assembly 50; the measuring assembly 60 is arranged close to the wearing surface of the shell.

[0045] In the embodiment of the present application, when the motor reset assembly 30 is in the first working state, the motor is used to drive the transmission assembly 50 to inflate the pressure pad 20; when the motor reset assembly 30 is in the second working state, the motor is used to generate vibration.

[0046] When the user wears the wearable device 1000 , if the pressure pad 20 is inflated, the pressure pad 20 applies pressure to the user's skin surface, so that the measurement component 60 obtains the user's physiological parameters.

[0047] It should be noted that when the user wears the wearable device 1000, the amount of air in the pressure pad 20 is positively correlated with the pressure applied by the pressure pad 20 to the user's skin surface; that is, the more air in the pressure pad 20, the greater the pressure applied by the pressure pad 20 on the user's skin surface.

[0048] In the embodiment of the present application, when the user wears the wearable device 1000, the wearing surface 11 of the housing 10 is the surface of the housing 10 close to the user's skin surface, that is, the wearing surface 11 of the housing 10 is the side wall of the housing 10 away from the display component 110 of the wearable device 1000. Figure 2 and Figure 3 As shown, the wearing surface 11 is arranged opposite to the display component 110 .

[0049] In the embodiment of the present application, the pressure pad is made of a flexible material, so when the pressure pad is inflated, the volume of the pressure pad will increase, that is, the pressure pad will expand, thereby applying pressure to the skin surface of the user.

[0050] In an embodiment of the present application, when a user wears the wearable device, the pressure pad can fit the user's skin surface, so that when the pressure pad is inflated, the pressure pad can apply pressure to the user's skin surface.

[0051] In the embodiment of the present application, the wearable device can pressurize / depressurize the wearer's skin surface by controlling the inflation and deflation of the air cushion.

[0052] Optionally, in the embodiment of the present application, the motor may be a vibration motor. When the motor reset assembly is in the second working state, the vibration motor may be used to generate vibrations to remind a user wearing the wearable device of an event, such as a timed event.

[0053] It can be understood that the embodiment of the present application reuses the original vibration motor in the wearable device to drive the transmission component to inflate the pressure pad, thereby eliminating the need for an additional motor, thereby saving internal space of the wearable device.

[0054] In the wearable device provided in the embodiment of the present application, on the one hand, when the motor reset component is in the first working state, the motor can drive the transmission component to inflate the air cushion, so that when the user wears the wearable device, the air cushion can apply pressure to the user's skin surface to effectively compress the user's blood vessels, thereby ensuring that the measurement component can measure the user's real physiological data. On the other hand, since when the motor reset component is in the first working state, the motor is used to drive the transmission component to inflate the pressure pad; when the motor reset component is in the second working state, the motor is used to generate vibration; that is, the motor can be switched between the inflation function and the vibration function through the motor reset component, so there is no need to set a special motor for the transmission component, so the volume of the wearable device capable of measuring physiological parameters can be reduced.

[0055] In this way, the wearable device provided in the embodiment of the present application can not only accurately obtain the physiological parameters of the user, but also reduce the size of the wearable device.

[0056] The motor reset assembly in the embodiment of the present application is exemplarily described below.

[0057] Optionally, in the embodiment of the present application, Figure 4 and Figure 5 The motor reset assembly 30 shown may include: a first electromagnetic coil 31 and a first reset spring 32. The first reset spring 32 is located between the first electromagnetic coil 31 and the motor, and two ends of the first reset coil are connected to the first electromagnetic coil 31 and the motor respectively.

[0058] Among them, Figure 5 As shown in (a), the first electromagnetic coil 31 is energized, and the first return spring 32 is in the first state under the magnetic force of the first electromagnetic coil 31, driving the motor to be in transmission connection with the transmission assembly 50. Figure 5 As shown in (b), the first electromagnetic coil 31 is de-energized, and the first return spring 32 is in the second state, driving the motor to separate from the transmission assembly 50.

[0059] Optionally, in the embodiment of the present application, the first return spring 32 includes a compressed state and a stretched state, and the first state and the second state are different. For example, the first state is a stretched state, and the second state is a compressed state (ie, a return state).

[0060] Optionally, in the embodiment of the present application, in mode 1, the first return spring may be a compression spring, that is, when not acted upon by an external force, the first return spring is in a stretched state, and at this time the first state is a stretched state (e.g. Figure 5 The second state is the compressed state (as shown in (a) in FIG. Figure 5 When the first electromagnetic coil is powered on, the magnetic force of the first electromagnetic coil on the first reset spring is a repulsive force, so that the first reset spring can be stretched under the action of the repulsive force, thereby driving the motor to be connected to the transmission component. When the first electromagnetic coil is powered off, the first electromagnetic coil does not generate a magnetic force, so that the first reset spring is reset and in a compressed state, thereby driving the motor to separate from the transmission component.

[0061] Optionally, in the embodiment of the present application, in mode 2, the first return spring is a tension spring, that is, when not acted upon by an external force, the first return spring is in a tension state, at which time the first state is a compression state, and the second state is a tension state. In the embodiment of the present application, when the first electromagnetic coil is powered on, the magnetic force of the first electromagnetic coil on the first return spring is an attraction force, so that the first return spring can be compressed and in a compression state under the action of the attraction force, thereby driving the motor to be connected to the transmission assembly; when the first electromagnetic coil is powered off, the first electromagnetic coil does not generate a magnetic force, thereby causing the first return spring to be reset and in a tension state, thereby driving the motor to be separated from the transmission assembly.

[0062] It can be seen that in mode 2, when the first return spring is in a compressed state, the motor is in transmission connection with the transmission assembly, and when the first return spring is in a stretched state, the motor is separated from the transmission assembly. Other descriptions of mode 2 will be described in detail in the following embodiments, and will not be repeated here to avoid repetition.

[0063] It can be understood that in the embodiment of the present application, when the first electromagnetic coil is energized, it indicates that the motor reset assembly is in the first working state, and when the first electromagnetic coil is de-energized, it indicates that the motor reset assembly is in the second working state.

[0064] It should be noted that the above embodiment is illustrated by taking the example that the first electromagnetic coil is energized, the motor is in transmission connection with the transmission component; the first electromagnetic coil is de-energized, and the motor is separated from the transmission component; in actual implementation, when the first electromagnetic coil is energized, the motor and the transmission component can be separated; when the first electromagnetic coil is de-energized, the motor and the transmission component can be in transmission connection. For example, taking the first return spring as a tension spring as an example, when the first electromagnetic coil is de-energized, the first return spring is in a tension state, and at this time the motor is in transmission connection with the transmission component (such as Figure 5 When the first electromagnetic coil is energized, the first electromagnetic coil generates an attraction force on the first return spring, so that the first return spring is compressed and in a compressed state, thereby driving the motor to separate from the transmission assembly (such as Figure 5 As shown in (b) in the figure). It can be understood that since the measurement of physiological parameters is intermittent or staged, compared with the scheme in which the first electromagnetic coil is powered off and the motor is in transmission connection with the transmission component, the transmission connection between the motor and the transmission component when the first electromagnetic coil is powered off can reduce the power consumption of the wearable device. In the following embodiments, unless otherwise specified, the transmission connection between the motor and the transmission component when the first electromagnetic coil is powered off is used as an example for illustration.

[0065] In the embodiment of the present application, the first return spring can be made of magnetic material.

[0066] It should be noted that in the embodiment of the present application, when the first electromagnetic coil is energized, the magnetic force generated by the first electromagnetic coil is greater than the elastic force of the first return spring, so that the first return spring can be in the first state under the action of the magnetic force and drive the motor to move toward the first electromagnetic coil, thereby separating the motor from the transmission assembly.

[0067] In the embodiment of the present application, the magnitude of the magnetic force generated by the first electromagnetic coil can be adjusted by adjusting the magnitude of the current passing through the first electromagnetic coil.

[0068] It is understood that in the embodiment of the present application, the deformation of the first return spring is greater than or equal to the target length. The target length is the overlapping length of the motor and the transmission assembly when the motor and the transmission assembly are in transmission connection, for example, the target length is the overlapping length of the drive gear and the transmission gear described below.

[0069] Optionally, in the embodiment of the present application, Figure 4 and Figure 5 As shown, a driving gear 41 may be provided on the output shaft of the motor. When the motor reset assembly 30 is in the first working state, the motor may be transmission-connected with the transmission assembly 50 through the driving gear 41. In this way, by resetting the motor reset assembly 30, the motor and the transmission assembly 50 may be transmission-connected or separated, thereby improving the switching efficiency of the switching motor function.

[0070] Optionally, in an embodiment of the present application, in method 2, when the first electromagnetic coil is energized, the motor can be connected to the transmission assembly 50 through the drive gear 41; when the first electromagnetic coil is de-energized, the output shaft of the motor can cross the transmission gear, that is, the transmission gear is located between the motor body and the drive gear, so that the motor can be separated from the transmission assembly.

[0071] It should be noted that the above embodiments are only exemplary descriptions of the motor reset assembly in the embodiments of the present application. In actual implementation, any structure that can achieve transmission connection and separation between the motor and the transmission assembly is within the protection scope of the embodiments of the present application.

[0072] The transmission assembly of the embodiment of the present application is exemplarily described below.

[0073] Optionally, in the embodiment of the present application, Figure 4 and Figure 6 As shown, the transmission assembly 50 may include: a transmission gear 51 , a transmission connecting rod 52 , a micro air pump 53 and an air pipe 54 .

[0074] In the embodiment of the present application, the transmission gear 51 can be used for transmission connection with the motor, the two ends of the transmission connecting rod 52 are respectively fixedly connected to the piston of the micro air pump 53 and the transmission gear 51, and the two ends of the air pipe 54 are respectively sealed and connected to the output end of the micro air pump 53 and the air inlet end 23 of the pressure pad.

[0075] Optionally, in the embodiment of the present application, when the motor reset assembly is in the first working state, the transmission gear can be meshed with the driving gear, thereby realizing a transmission connection between the motor and the transmission assembly.

[0076] like Figure 5 As shown, the motor in the embodiment of the present application has two position states: meshing state & separation state. The first electromagnetic coil 31 is energized, and under the action of the first reset spring 32, the transmission gear 51 and the drive gear 41 are meshed, that is, the motor is in a meshing state, and the rotation of the motor will drive the micro air pump 53 to work. The first electromagnetic coil 31 is de-energized, the first reset spring 32 is reset (i.e., compressed), the transmission gear 51 and the drive gear 41 are separated, that is, the motor 40 is in a separation state, and the rotation of the motor 40 is used for the wearable device 1000 itself to vibrate for event reminders.

[0077] Optionally, in the embodiment of the present application, Figure 6 As shown, an eccentric shaft is provided on the side of the transmission gear 51 facing the transmission connecting rod 52, and the transmission gear 51 is fixedly connected to the transmission connecting rod 52 through the eccentric shaft. Specifically, one end of the transmission connecting rod 52 is sleeved on the eccentric shaft.

[0078] Optionally, in the embodiment of the present application, Figure 6As shown, a connecting shaft is provided on the piston of the micro air pump 53, and the piston is fixedly connected to the transmission connecting rod 52 through the connecting shaft. Specifically, the other end of the transmission connecting rod 52 is sleeved on the connecting shaft.

[0079] In the embodiment of the present application, when the transmission gear is meshed with the driving gear, when the motor is working, the transmission assembly can convert the rotational motion of the motor into the linear reciprocating motion of the micro air pump, so that the gas enters the pressure pad through the air pipe, and then the micro air pump can be used to inflate the air pressure pad. In this way, the pressure pad can be pressurized.

[0080] Combine the following Figure 6 The working principle of the transmission assembly is explained exemplarily.

[0081] For example, Figure 6 As shown, the motor is fixedly connected to the transmission gear 51, and the transmission gear 51 is meshed with the driving gear 41. When the motor rotates, the transmission gear 51 is driven to rotate through the driving gear 41. The two ends of the transmission connecting rod 52 are respectively fixedly connected to the transmission gear 51 and the piston 536 of the micro air pump. Driven by the transmission connecting rod 52, the piston 536 reciprocates in the cavity of the micro air pump 53 and pumps air into the air pipe 54.

[0082] Specifically, Figure 6 As shown, the output end of the micro air pump 53 is sequentially provided with a second one-way valve 531, a third return spring 532, a connecting pipe, an air pump cap 533 and a gas flow pipe 534. Among them, the two ends of the third return spring 532 are respectively fixedly connected to the output end of the micro air pump and the connecting pipe, the connecting pipe and the gas flow pipe are both fixedly connected to the air pump cap, and the air flow connecting pipe can be sealed and connected to the air inlet of the pressure pad.

[0083] In the embodiment of the present application, the third return spring may be a tension spring. When the motor drives the piston of the micro air pump to linearly reciprocate in the piston chamber, the airflow may squeeze the second one-way valve and the third return spring, so that the second one-way valve is separated from the output end of the micro air pump, thereby achieving inflation of the pressure pad. Since the second one-way valve and the third return spring are provided, the micro air pump can prevent the gas in the pressure pad from flowing back and overflowing from the output end of the micro air pump.

[0084] In this way, the rotational motion of the motor can be converted into the linear reciprocating motion of the piston through the cooperation of the transmission gear and the transmission connecting rod, so that the micro piston can inflate the pressure pad.

[0085] Optionally, in the embodiment of the present application, Figure 7 As shown, the wearing surface 11 of the shell 10 has a light-transmitting area 11 - 1 , and the measuring component 60 is arranged close to the light-transmitting area 11 - 1 .

[0086] Optionally, in an embodiment of the present application, a through hole is provided on the wearing surface of the shell, and the light-transmitting sheet can be embedded in the through hole.

[0087] Optionally, in the embodiment of the present application, the light-transmitting sheet may be deformed so that a pressure sensor in a measuring assembly corresponding to the light-transmitting sheet can perform pressure measurement.

[0088] Optionally, in the embodiment of the present application, the size of the through hole and the size of the light-transmitting sheet can be determined according to the size of the measuring component to ensure that the entire measuring component can be arranged corresponding to the light-transmitting sheet.

[0089] In the embodiment of the present application, since the wearing surface of the shell is provided with a light-transmitting area, and the measuring component is provided corresponding to the light-transmitting area, it can be ensured that the measuring component can accurately measure the physiological parameters.

[0090] Optionally, in the embodiment of the present application, Figure 7 As shown, the measurement component 60 may include: a physiological parameter measurement unit 61 and a pressure measurement unit 62 .

[0091] In the embodiment of the present application, there is a gap between the physiological parameter measurement unit and the light-transmitting area, and the pressure measurement unit abuts against the light-transmitting area.

[0092] The projection areas of the physiological parameter measurement unit and the pressure measurement unit on the light-transmitting area do not overlap, so that mutual interference between the physiological parameter measurement unit and the pressure measurement unit can be avoided, thereby improving the accuracy of the measurement result.

[0093] Optionally, in an embodiment of the present application, the physiological parameter measurement unit can be used to measure the physiological parameters of the user, and the pressure measurement unit can be used to measure the pressure of the pressure pad on the skin surface of the user.

[0094] Optionally, in the embodiment of the present application, the size of the gap between the physiological parameter measurement unit and the light-transmitting sheet can be set according to actual measurement requirements, and is not limited in the embodiment of the present application.

[0095] Optionally, in an embodiment of the present application, the physiological parameter measurement unit may include: a heart rate sensor, an ECG sensor, and a blood pressure sensor, for real-time monitoring of the user's health status.

[0096] Optionally, in the embodiment of the present application, the pressure measurement unit may include: a pressure sensor for monitoring whether the housing of the wearable device is pressed tightly against the user's skin surface. Moreover, the wearable device may intelligently pressurize or depressurize the pressure pad based on the measurement result of the pressure measurement unit.

[0097] In this way, since the projection areas of the physiological parameter measurement unit and the pressure measurement unit in the measuring component on the light-transmitting sheet do not overlap, and there is a gap between the physiological parameter measurement unit and the light-transmitting sheet, and the pressure measurement unit is in contact with the light-transmitting sheet, during the process of measuring physiological parameters, both the physiological parameter measurement unit and the pressure measurement unit can work accurately without affecting each other, so that accurate relevant data can be measured.

[0098] Optionally, in the embodiment of the present application, Figure 3 As shown, the pressure pad 20 may include: an annular pad body 21 and two pressure belts 22 symmetrically arranged on the annular pad body 21 .

[0099] Optionally, in the embodiments of the present application, in method a, the interior of the annular pad is hollow, and the two pressure belts are not provided with an inner cavity; in method b, the annular pad and the two pressure belts are both hollow, and the inner cavity of the annular pad and the inner cavity of the two pressure belts are interconnected, so that the user's skin surface pressure can be better adjusted.

[0100] In the embodiment of the present application, the annular pad is arranged on the wearing surface of the shell, and the projection area of ​​the annular pad on the wearing surface does not overlap with the light-transmitting area.

[0101] It can be understood that when a user wears the wearable device, the surfaces of the annular pad and the two pressure belts facing away from the wearing surface of the shell fit the user's skin, thereby better exerting pressure on the user's skin surface.

[0102] Optionally, in an embodiment of the present application, when the wearable device is a smart watch, the pressure pad can be used as a strap of the smart watch.

[0103] Optionally, in the embodiment of the present application, Figures 1 to 3 As shown, the wearable device 1000 may further include: a watchband 100. The watchband 100 may include two sub-watchbands 101; the two sub-watchbands 101 are symmetrically arranged on the housing 10. The watchband 100 is used to fix the wearable device 1000 on the wrist of the wearer.

[0104] Optionally, in an embodiment of the present application, the strap 100 is also used to fix the pressure pad 20. Specifically, the two pressure straps 22 are respectively fitted with the surfaces of the two sub-straps 101 away from the shell 10, so that when the user wears the wearable device 1000, the pressure pad 20 can fit the user's skin surface.

[0105] Optionally, in the embodiment of the present application, combined with Figure 8 ,like Fig.10 As shown, the wearable device may further include: a pressure relief component 70 . The pressure relief component is embedded on the wearing surface 11 of the housing corresponding to the air outlet end of the pressure pad 20 , and the pressure pad 20 is depressurized through the pressure relief component 70 .

[0106] In this way, the inflation (pressurization) and pressure relief of the pressure pad can be achieved through the cooperation of the pressure relief component with the motor and the transmission component.

[0107] Optionally, in the embodiment of the present application, the pressure relief assembly may include: a first one-way valve and a one-way valve resetting unit.

[0108] In the embodiment of the present application, the one-way valve reset unit is embedded in the wearing surface of the shell, and the first one-way valve is arranged on the one-way valve reset unit and is located between the one-way valve reset unit and the air outlet end of the pressure pad.

[0109] Among them, when the one-way valve reset unit is in the third working state, the first one-way valve is sealed and connected to the air outlet end of the pressure pad; when the one-way reset unit is in the fourth working state, the one-way reset valve is separated from the air outlet end of the pressure pad to relieve pressure on the pressure pad.

[0110] In this way, since the pressure relief or sealing of the pressure pad can be achieved by switching the working state of the one-way valve reset unit, the operational flexibility of sealing and relieving the pressure of the pressure pad can be improved.

[0111] The one-way valve resetting unit is described below by way of example.

[0112] Optionally, in the embodiment of the present application, combined with Figure 8 ,like Fig.10 As shown, Fig.10 A schematic diagram of the output of the pressure pad is shown in FIG. Fig.10 As shown, the one-way valve reset unit may include: a second electromagnetic coil 72 and a second reset spring 73. The second electromagnetic coil 72 is embedded on the wearing surface 11 of the housing, the second reset spring 73 is located between the second electromagnetic coil 72 and the first one-way valve 71, and the two ends of the second reset spring 73 are respectively connected to the second electromagnetic coil 72 and the first one-way valve 71.

[0113] Among them, in mode 3, the second electromagnetic coil 72 is powered off, the second return spring 73 is stretched, and the first one-way valve 71 is driven to be sealed and connected with the outlet end 24 of the pressure pad; the second electromagnetic coil 72 is powered on, the second return spring 73 is compressed, and the first one-way valve 71 is driven to be separated from the outlet end 24 of the pressure pad, so as to relieve the pressure of the pressure pad 20. Alternatively, in mode 4, the second electromagnetic coil is powered on, the second return spring is stretched, and the first one-way valve is driven to be sealed and connected with the outlet end; the second electromagnetic coil is powered off, the second return spring is compressed, and the first one-way valve is driven to be separated from the outlet end, so as to relieve the pressure of the pressure pad.

[0114] It can be understood that in method 3, the second return spring is a tension spring, and when the second electromagnetic coil is energized, an attractive force is applied to the second return spring to compress the second return spring; in method 4, the second return spring is a compression spring, and when the second electromagnetic coil is energized, a repulsive force is applied to the second return spring to stretch the second return spring.

[0115] In the embodiment of the present application, when the second return spring is stretched, it indicates that the one-way valve return assembly is in the third working state, and when the second return spring is compressed, it indicates that the one-way valve return assembly is in the fourth working state.

[0116] In this way, by disconnecting or energizing the second electromagnetic coil, the first one-way valve and the air outlet end of the pressure pad can be sealed or separated, so that the pressure pad can be easily sealed and depressurized.

The fixed transmission bracket can be fixed on the circuit board by a fixing member, such as a locking screw.

[0122] Optionally, in the embodiment of the present application, Figure 1 , Fig. 9 and Fig.10 As shown, the wearable device 1000 may further include two seals 120, which are respectively arranged at the air outlet end of the pressure pad 20 and the air inlet end 23 of the pressure pad. The seal 120 is used to prevent the gas in the pressure pad 20 from leaking out and water from entering the pressure pad 20.

[0123] For example, combined with Figure 8 ,like Fig. 9 As shown, Fig. 9 It is an enlarged schematic diagram of the air inlet end of the pressure pad. The air pipe 54 passes through the wearing surface 11 of the shell 10 and is connected to the air inlet end of the air pad. The sealing member 120 is embedded between the air pipe and the wearing surface 11.

A through hole is arranged on the decorative ring 12, and the display assembly of the wearable device 1000 is embedded in the decorative ring 12. The circuit board 90 is located on the side of the touch screen assembly facing the middle frame.

[0125] It can be understood that the wearing surface of the above-mentioned shell is the surface of the lower cover assembly facing away from the frame body.

[0126] Optionally, in the present embodiment, the display component may specifically be a touch screen display component, such as a touch display screen.

[0127] Optionally, in the embodiment of the present application, the motor reset assembly, the motor, and the transmission assembly are all arranged on the main board.

[0128] Optionally, in an embodiment of the present application, the circuit board is fixed to the frame by means of fixing members, such as screws.

[0129] The present application also provides a method for measuring physiological data. Fig.11 A possible flow chart of the physiological data measurement method provided in an embodiment of the present application is shown, and the method can be applied to the above-mentioned wearable device, such as Fig.11 As shown, the method may include the following steps 801 and 802. The following is an exemplary description of the method performed by a wearable device as an example.

[0130] Step 801: When a user wears the wearable device, the wearable device controls the motor reset component to be in a first working state, and controls the motor to work, so as to drive the transmission component to inflate the pressure pad, and control the pressure pad to apply pressure to the user's skin surface.

[0131] Step 802: When the pressure applied by the pressure pad to the user's skin surface is greater than or equal to the pressure threshold, the wearable device controls the motor to stop working, controls the motor reset component to be in the second working state, and controls the measurement unit to start measuring the user's physiological parameters.

[0132] It should be noted that, in the embodiment of the present application, the pressure threshold is the pressure required for measuring physiological parameters.

[0133] For example, taking the wearable device as a smart watch, the pressure threshold is the pressure that can block the user's brachial artery.

[0134] Optionally, the physiological parameter measurement method provided in the embodiment of the present application may further include the following step 803.

[0135] 803. In the process of controlling the measuring unit to measure the physiological parameters, the pressure pad is controlled by the pressure relief component to relieve pressure according to a preset pressure relief strategy.

[0136] The preset pressure relief strategy is determined according to the type of physiological parameter that needs to be measured.

[0137] For example, when the physiological parameter is blood pressure, the preset pressure relief strategy may be to relieve pressure at a rate of 5 mmHg every 4 seconds.

[0138] In this way, since the pressure relief strategy of the pressure pad can be determined according to the type of physiological parameter to be measured, it can be ensured that the pressure applied by the pressure pad to the user's skin surface meets the physiological parameter measurement requirements in real time.

[0139] Optionally, in the embodiment of the present application, after the above step 802, the physiological parameter measurement method provided in the embodiment of the present application may further include the following step 804.

[0140] Step 804: When the motor reset component is in the second working state, control the motor to operate so as to vibrate the wearable device.

[0146] The control module 1201 is also used to control the motor to stop working, control the motor reset component to be in the second working state, and control the measurement unit to start measuring the user's physiological parameters when the pressure applied by the pressure pad to the user's skin surface is greater than or equal to the pressure threshold.

[0147] In a possible implementation, the control module 1201 may also be used to control the pressure pad to release pressure according to a preset pressure release strategy through the pressure release component during the process of controlling the measurement unit to measure the physiological parameters;

[0148] The preset pressure relief strategy is determined according to the type of physiological parameter that needs to be measured.

[0149] In a possible implementation, the control module 1201 may also be used to control the motor to operate so as to vibrate the wearable device after the control measurement unit measures the physiological parameters of the user and when the motor reset component is in the second working state.
