[0001] This application relates to the field of electronic devices, and more particularly, to a method for detecting wearing, an adjustment mechanism, and a wearable device. Background Art

[0002] Nowadays, people pay more and more attention to the health conditions of themselves and their families. Blood pressure measurement, heart rate measurement, blood oxygen measurement, etc. are particularly important. With the progress and development of technology, functions such as blood pressure measurement, heart rate measurement, and blood oxygen measurement have also begun to be integrated into some wearable devices (such as smart watches or smart bracelets, etc.), which provides the possibility for users to measure at any time and place. When performing the above measurements, too tight or too loose wearing of the wearable device by the user will affect the measurement accuracy. Therefore, how to detect whether the wearable device is worn properly and quickly adjust the tightness has become a technical problem to be solved urgently. Summary of the Invention

[0003] This application provides a method for detecting wearing, an adjustment mechanism, and a wearable device, which can quickly detect wearing and adjust the tightness, helping to improve the user experience.

[0004] In a first aspect, a method for detecting the wearing of a wearable device is provided. The wearable device includes a blood pressure detection component and a pressure sensor. The blood pressure detection component includes an airbag and an air pump. The pressure sensor is used to detect the air pressure before the gas flows into the airbag. The method includes: detecting that a preset condition is met and filling the airbag with gas; during the process of filling the airbag with gas, obtaining the air pressure value of the pressure sensor; determining the wearing detection result of the wearable device according to the air pressure value of the pressure sensor; and displaying a first interface, where the first interface includes the wearing detection result.

[0005] In the embodiments of this application, the wearable device can determine whether the wearing is normal by detecting the air pressure before the gas flows into the airbag, ensuring the accuracy of the physiological parameter measurement result and helping to improve the user experience.

[0006] In combination with the first aspect, in some implementation manners of the first aspect, adjustment prompt information is determined according to the air pressure value of the pressure sensor; and the adjustment prompt information is displayed on the first interface.

[0007] In the embodiments of this application, the wearable device can also set more thresholds, so that the wearable device can more accurately and better judge the degree of looseness or tightness in the case of determining that the wearing is too loose or too tight.

[0008] In combination with the first aspect, in certain implementations of the first aspect, the air pressure value of the air pressure sensor is negative. Determining the wearing detection result of the wearable device according to the air pressure value of the air pressure sensor includes: when the air pressure value of the air pressure sensor is greater than a first threshold, determining that the wearing is too tight; when the air pressure value of the air pressure sensor is less than a second threshold, determining that the wearing is too loose; when the air pressure value of the air pressure sensor is greater than or equal to the second threshold and less than or equal to the first threshold, determining that the wearing is normal.

[0009] In combination with the first aspect, in certain implementations of the first aspect, an operation of the user triggering the measurement of physiological parameters is detected; and / or an operation of the user triggering the detection of the wearing tightness of the wearable device is detected; and / or the difference between the measured physiological parameter value and the average value of the physiological parameter values measured within a first time period is detected to be greater than a third threshold.

[0010] In a second aspect, a method for detecting the wearing of a wearable device is provided. The wearable device includes a blood pressure detection component, a first temperature sensor, a second temperature sensor, and a heat source. The blood pressure detection component includes an airbag and an air pump. When the air pump is started, the gas sequentially flows through the first temperature sensor, the heat source, and the second temperature sensor. The method includes: detecting that a preset condition is met, filling the airbag with gas and starting the heat source; during the process of filling the airbag with gas, obtaining the temperature value of the first temperature sensor and the temperature value of the second temperature sensor; determining the wearing detection result of the wearable device according to the temperature value of the first temperature sensor and the temperature value of the second temperature sensor; and displaying a first interface, where the first interface includes the wearing detection result.

[0011] In the embodiments of the present application, the wearable device can determine whether the wearing is normal by detecting the difference in the temperatures measured by two temperature sensors, which ensures the accuracy of the physiological parameter measurement results and helps to improve the user experience.

[0012] In combination with the second aspect, in certain implementations of the second aspect, the method further includes: determining an adjustment prompt message according to the temperature value of the first temperature sensor and the temperature value of the second temperature sensor; and displaying the adjustment prompt message on the first interface.

[0013] In the embodiments of the present application, the wearable device can also set more thresholds, so that the wearable device can more accurately and better judge the degree of looseness or tightness when it is determined that the wearing is too loose or too tight.

[0014] In combination with the second aspect, in some implementations of the second aspect, determining the wearing detection result of the wearable device based on the temperature value of the first temperature sensor and the temperature value of the second temperature sensor includes: determining the wearing detection result of the wearable device based on the difference between the temperature value of the first temperature sensor and the temperature value of the second temperature sensor.

[0015] In combination with the second aspect, in some implementations of the second aspect, the difference between the temperature value of the first temperature sensor and the temperature value of the second temperature sensor is negative. Determining the wearing detection result of the wearable device based on the difference between the temperature value of the first temperature sensor and the temperature value of the second temperature sensor includes: when the difference between the temperature value of the first temperature sensor and the temperature value of the second temperature sensor is greater than a first threshold, determining that the wearing is too tight; when the difference between the temperature value of the first temperature sensor and the temperature value of the second temperature sensor is less than a second threshold, determining that the wearing is too loose; when the difference between the temperature value of the first temperature sensor and the temperature value of the second temperature sensor is greater than or equal to the second threshold and less than or equal to the first threshold, determining that the wearing is normal.

[0016] In combination with the second aspect, in some implementations of the second aspect, detecting that a preset condition is satisfied includes: detecting an operation by the user to trigger the measurement of physiological parameters; and / or detecting an operation by the user to trigger the detection of the wearing tightness of the wearable device; and / or detecting that the difference between the measured physiological parameter value and the average value of the physiological parameter values measured within a first time period is greater than a third threshold.

[0017] In a third aspect, an adjustment mechanism is provided. The adjustment mechanism includes: a housing 810, which includes an accommodation space, and further includes an outer surface and an inner surface. A one-way guide rail 8101 is provided on the inner surface, and the one-way guide rail 8101 is arranged along the length direction of the watch band. The housing 810 is further provided with an opening 8102 that penetrates the outer surface and the inner surface. Wherein, the length direction of the watch band includes a first direction and a second direction, and the first direction and the second direction are opposite. The direction from the inner surface pointing to the outer surface and perpendicular to the first direction and the second direction is the third direction; a fine-tuning slider 820, which is configured to be slidable in the accommodation space along the first direction and the second direction, and the fine-tuning slider 820 is connected to the first watch band to drive the first watch band to move in the first direction and the second direction; an adjustment button 830, which passes through the opening 8102 and is connected to the fine-tuning slider 820 through a first elastic component 850. The adjustment button is provided with sliding teeth 8301. When the first elastic component 850 is in a first state, the sliding teeth 8301 are engaged with the one-way guide rail 8201. When the first elastic component 850 is in a second state, the sliding teeth 8301 are disengaged from the one-way sliding rail 8101; a connection component 840, which is arranged on the outer surface of the housing 810 and is used to connect the second watch band; a second elastic component 860, which is arranged in the accommodation space and abuts against the inner surface of the housing 810 and the fine-tuning slider 820.

[0018] The usage method of the adjustment mechanism provided by the embodiment of the present application is as follows. Taking the one-way guide rail 8101 being in the second direction as an example, when the user wears the wearable device on the wrist or upper arm, etc., when the user feels that the wearing is loose, or the wearable device detects that the wearing is loose, the user can push the adjustment button 830 in the second direction. The adjustment button 830 can drive the fine-tuning slider 820 to slide in the second direction. Since the fine-tuning slider 820 is connected to the first watch band 900, it also drives the first watch band 900 to move in the second direction, thereby achieving the purpose of tightening. It can be understood that when the user tightens, there is no need to press the adjustment button 830. When the user feels that the wearing is tight, or the wearable device detects that the wearing is tight, the user can press the adjustment button 830 so that the sliding teeth 8301 on the adjustment button 830 are disengaged from the saw teeth on the one-way guide rail 8101. Under the push of the second elastic component 860, the fine-tuning slider 820 slides in the first direction, thereby achieving the purpose of loosening. When the user determines that the adjustment is appropriate, the user can stop pressing the adjustment button 830. Then, the adjustment button 830 will move in the third direction under the push of the first elastic component 850, so that the sliding teeth 8301 are engaged with the saw teeth on the one-way guide rail 8101 again. Under the block of the saw teeth, it can block the fine-tuning slider 820 from sliding in the first direction, thereby achieving the purpose of locking. It can be understood that since the fine-tuning slider 820 can slide in the first direction under the push of the second elastic component 860, the user can operate with only one hand, and the operation is simple.

[0019] Combined with the third aspect, in some implementation manners of the third aspect, the direction of the one-way guide rail 8101 is the second direction, and when the fine-tuning slider 820 slides in the second direction, the second elastic component 860 is in a compressed state.

[0020] Combined with the third aspect, in some implementation manners of the third aspect, the direction of the one-way guide rail 8101 is the first direction, and when the fine-tuning slider 820 slides in the first direction, the second elastic component 860 is in a compressed state.

[0021] Combined with the third aspect, in some implementation manners of the third aspect, the length of the one-way guide rail 8101 in the first direction is less than or equal to the length of the opening 8102 in the first direction.

[0022] Combined with the third aspect, in some implementation manners of the third aspect, the diameter of the opening 8102 near the outer surface of the housing 810 is larger than the diameter of the opening 8102 near the inner surface of the housing 810.

[0023] In the embodiment of the present application, the opening 8102 has a variable diameter and the diameter near the outer surface of the upper housing is larger, which can give the user a larger operating space, facilitate the user's better operation, and help improve the user experience.

[0024] In combination with the third aspect, in some implementation manners of the third aspect, the housing 810 includes an upper housing and a bottom plate. One side of the upper housing close to the bottom plate includes a chute 8103 and a positioning screw hole 8104, and the upper housing and the bottom plate are fixedly connected through the chute 8103 and a screw.

[0025] In the embodiment of the present application, after the upper housing and the bottom plate are connected through the chute 8103, since the chute 8103 already provides a certain supporting effect, the upper housing does not need to be provided with positioning screw holes 8104 on all four sides. Only the positioning screw holes 8104 are arranged on both sides of the end far from the first watch band 900 and are fixedly connected through screws. When the upper housing and the bottom plate are fixedly connected, a screw is used, and the screw has no head, so the overall thickness of the adjusting mechanism 800 at the end far from the first watch band can be reduced.

[0026] In combination with the third aspect, in some implementation manners of the third aspect, the length of the one-way guide rail 8101 in the first direction is equal to the distance between two adjacent pin holes on the first watch band or the second watch band.

[0027] In the embodiment of the present application, the length of the one-way guide rail 8101 of the adjusting mechanism 800 in the first direction is equal to the distance between two adjacent pin holes on the watch band, so that when the tightness is adjusted, an adjustment smaller than a smaller amplitude can be achieved, the adjustment accuracy is improved, and the user experience is helped to be enhanced.

[0028] In combination with the third aspect, in some implementation manners of the third aspect, the length of each tooth of the one-way guide rail 8101 in the first direction is 0.8 - 1.2 mm.

[0029] In combination with the third aspect, in some implementation manners of the third aspect, the adjusting button 830 further includes a platform 8302, wherein the sliding tooth 8301 is arranged on the platform 8302.

[0030] In combination with the third aspect, in some implementation manners of the third aspect, the length of the platform 8302 in the first direction is greater than the length of the sliding tooth 8301 in the first direction.

[0031] In combination with the third aspect, in some implementation manners of the third aspect, the fine-tuning slider 820 is further provided with a groove 8201. The adjusting button 830 is inserted into the groove 8201 through the opening 8102, and the first elastic component 850 abuts against the adjusting button 830 and the groove 8201.

[0032] In combination with the third aspect, in some implementation manners of the third aspect, when the sliding tooth 8301 of the adjusting button 830 meshes with the last tooth of the one-way guide rail 8101 in the first direction, the second elastic component 860 is in a normal state.

[0033] In combination with the third aspect, in some implementation manners of the third aspect, the degree of compression of the first elastic component 850 in the first state is less than the degree of compression in the second state.

[0034] In combination with the third aspect, in some implementation manners of the third aspect, the first state is the first compression state.

[0054] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings.

[0055] The terms used in the following embodiments are only for the purpose of describing specific embodiments and are not intended to limit the present application. As used in the specification and appended claims of the present application, the singular forms "a", "an", "the", "above-mentioned", "said", and "this" are also intended to include expressions such as "one or more", unless the context clearly indicates otherwise. It should also be understood that in the following embodiments of the present application, "at least one" and "one or more" mean one, two, or more than two. The term "and / or" is used to describe the association relationship of associated objects and indicates that three relationships can exist; for example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0056] Reference to "one embodiment" or "some embodiments" etc. described in this specification means that a specific feature, structure, or characteristic described in connection with that embodiment is included in one or more embodiments of the present application. Thus, statements such as "in one embodiment", "in some embodiments", "in other some embodiments", "in still other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "comprise", "include", "have" and their variants all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0057] The wearable device provided by the present application can be a portable device that can be integrated into the user's clothes or accessories, has computing functions, and can be connected to a mobile phone and various terminal devices. Exemplarily, the wearable device 100 can be a smart watch, a blood pressure bracelet, an upper arm blood pressure monitor, etc. The present application does not make specific limitations on the type of the wearable device.

[0058] It should be noted that the wearable device provided by the embodiments of the present application has a blood pressure measurement function and / or a blood oxygen measurement function and / or a heart rate measurement function.

[0059] The wearable device generally uses the principle of the oscillometric method to measure blood pressure. Specifically, when blood flows, the vibration caused by the collision of the blood vessel wall is used to obtain the fluctuation envelope from the blood vessel wall, and the blood pressure value is obtained through the relationship between the fluctuation envelope and the arterial blood pressure. During specific measurement, the wearable device needs to be worn on a person's limb, and the airbag of the wearable device is used to compress the artery of the user being measured. When the blood pressure in the artery of the user being measured impacts the airbag, the air pressure inside the airbag generates a pressure fluctuation, and then the blood pressure index of the user being measured is calculated based on the fluctuation of the air pressure inside the airbag.

[0060] Wearable devices usually use the optoelectronic measurement method to measure heart rate. Specifically, a beam of light is emitted onto the skin surface. By the change in blood flow caused by the heartbeat, the light intensity at different times is obtained, and the heart rate value is obtained through the light intensity at different times. Similar to blood pressure measurement, when measuring heart rate, the wearable device needs to be worn on a person's limb. When a beam of light with a fixed wavelength is irradiated onto the skin surface, the light will be transmitted or reflected to the sensor. During this process, the light intensity detected by the sensor will decrease due to absorption by the skin, muscles, and blood. The absorption of light by the skin, muscle tissue, etc. remains constant throughout the blood circulation, but the blood volume in the skin changes pulsatively under the action of the heart. When the heart contracts, the peripheral blood volume is the largest, the light absorption is also the largest, and the detected light intensity is the smallest. When the heart relaxes, on the contrary, the detected light intensity is the largest, that is, the detected light intensity changes pulsatively, and thus the heart rate value of the user is calculated.

[0061] Wearable devices usually use the optoelectronic measurement method to measure blood oxygen. Specifically, red light and infrared light are emitted onto the skin surface. Since oxygenated hemoglobin is reddish, when receiving red light irradiation, the reflectivity of red light is relatively high, while the reflectivity of infrared light is relatively low. On the contrary, when the oxygenated hemoglobin is oxygen-deficient, the reflectivity of red light is relatively low, and the reflectivity of infrared light is relatively high. By analyzing the different reflectivities of red light and infrared light, the blood oxygen value is obtained. Similar to heart rate measurement, when measuring blood oxygen, the wearable device needs to be worn on a person's limb.

[0062] In summary, when the wearable device performs the above measurement functions, the wearable device needs to be worn on a person's limb, but the tightness of the wearing will affect the accuracy of the measurement results. Taking blood pressure measurement as an example, for example, if the wearable device is worn too loosely, the airbag needs to be inflated with more gas to compress the artery of the user being measured. At this time, the pressure in the airbag is increased compared with normal wearing, which will cause the measured blood pressure value to be too high. On the contrary, if the wearable device is worn too tightly, the pressure in the airbag is decreased compared with normal wearing, which will cause the measured blood pressure value to be too low. It can be seen that the tightness of wearing the wearable device will affect the accuracy of the measurement results. Based on this, the embodiments of the present application provide a method for wearing detection and a wearable device.

[0063] Figure 1 It is a schematic structural diagram of a wearable device 100 provided by an embodiment of the present application. In some embodiments, the wearable device 100 may be a smart watch or a bracelet that can be worn around the user's wrist.

[0064] As Figure 1As shown, the wearable device 100 may include a main body 110, a wristband 120, and a blood pressure detection component 130. Among them, the wristband 120 can surround and fit to a body part of the user, such as the user's wrist, upper arm, ankle, or other parts of the body, so as to fit and wear the main body 110 on the part of the user to be detected. The wearable device 100 can implement the blood pressure measurement function through the blood pressure detection component 130.

[0065] The blood pressure detection component 130 may include an airbag 131, an air pump 132, and a barometric pressure sensor (not shown in the figure). Among them, the airbag 131 can be arranged on the inner surface of the wristband 120. The air pump 132 can be arranged inside the main body 110 and communicated with the airbag 131 through an air tube 133, and is used to inflate or deflate the airbag 131. The barometric pressure sensor can also be arranged inside the main body 110 and connected to the airbag 131, and is used to detect the barometric pressure change of the airbag 131.

[0066] It can be understood that the inner surface of the wristband 120 can be the side of the wristband 20 that fits and contacts the body part of the user.

[0067] Exemplarily, when the user measures blood pressure through the wearable device 100 worn on the wrist, the wearable device 100 can control the air pump 132 to start the inflation operation. The air pump 132 can inflate the airbag 31 through the air tube 133, so that the airbag 131 pressurizes and expands, thereby compressing the radial artery of the wrist. In this case, the barometric pressure in the airbag 131 can generate barometric pressure fluctuations. The wearable device 100 can obtain the barometric pressure wave signal in the airbag 131 through the barometric pressure sensor, and calculate the diastolic blood pressure and systolic blood pressure of the user based on the barometric pressure wave signal, so as to implement the blood pressure measurement function.

[0068] After the blood pressure measurement process ends, the wearable device 100 can control the air pump 132 to stop the inflation operation, and the gas in the airbag 131 can be discharged through the air pump 132 to be in a state where blood pressure can be re-measured.

[0069] Optionally, in some embodiments, the wearable device may further include a photoplethysmography (PPG) sensor, which is used to collect the heart rate and blood oxygen of the user.

[0070] Next, the method for wearing detection provided by the embodiments of the present application will be introduced in combination with a graphical user interface (GUI).

[0071] It should be noted that in the GUI involved below, a smart watch is taken as an example of the wearable device for illustration, but it should not be construed as a specific limitation on the embodiments of the present application.

[0072] Figure 2 Shows a group of GUIs provided by an embodiment of the present application.

[0073] As Figure 2 shown in (a) of the figure, the smartwatch display interface 201, and the interface 201 can be a desktop. The smartwatch displays an icon 202 on the interface 201, and the icon 202 corresponds to the blood pressure measurement function. When the smartwatch detects an operation of the user clicking the icon 202, it can respond to this operation and display a GUI as shown in Figure 2 (b) of the figure.

[0074] As Figure 2 shown in (b) of the figure, in response to the user clicking the icon 202, the smartwatch can perform blood pressure measurement and display the blood pressure measurement result on the interface 203.

[0075] As Figure 2 shown in (c)-(d) of the figure, the smartwatch can store the average value of blood pressure measurement results in the past period (for example, one week). The smartwatch can compare the difference between the average value and the current blood pressure measurement result. When the difference between the two is greater than the threshold, the smartwatch can display an option box 204, and the option box 204 is used to output a prompt message, and the prompt message is used to prompt the user whether to perform wearing detection. When the smartwatch detects an operation of the user clicking the OK control 205, it can perform wearing detection and display the detection result on the interface 206 after the detection is completed: "The current wearing is too tight. Please adjust it in time before performing blood pressure measurement."

[0076] In the embodiment of the present application, the smartwatch can detect whether the user is wearing it properly, thereby ensuring the accuracy of functions such as blood pressure measurement, heart rate measurement, and blood oxygen measurement, and helping to improve the user experience.

[0077] It should be noted that for the method of the smartwatch detecting the wearing tightness, please refer to the following text and will not be elaborated here.

[0078] It should also be noted that Figure 2 in the example shown, taking the smartwatch first performing blood pressure detection and then triggering wearing detection when it is determined that there is a large difference between the currently measured blood pressure value and the previously measured blood pressure value as an example, but the embodiment of the present application is not limited thereto. In some other embodiments of the present application, the smartwatch can also perform wearing detection when it is determined that other conditions are met.

[0079] For example, taking the Figure 2 GUI shown in the figure as an example, in response to the user clicking the icon 202, the smartwatch can first perform wearing detection, and after determining that the wearing is normal, then perform blood pressure measurement.

[0080] For another example, the smart watch may display an icon on the desktop, and the icon corresponds to the wearing detection function. In response to the user clicking the icon, the smart watch may perform wearing detection and display the wearing result in the interface.

[0081] For another example, the smart watch may display an icon on the desktop, which corresponds to the heart rate detection function. In response to the user clicking the icon, the smart watch may first perform a wearing detection, and then perform a heart rate detection after determining that the wearing is normal, or first perform a heart rate detection, and then trigger a wearing detection when determining that the heart rate value measured this time is significantly different from the heart rate value measured previously.

[0082] For another example, the smart watch may display an icon on the desktop, which corresponds to the blood oxygen detection function. In response to the user clicking the icon, the smart watch may first perform a wearing detection, and then perform a blood oxygen detection after determining that the wearing is normal, or first perform a blood oxygen detection, and then trigger a wearing detection when it is determined that the blood oxygen value measured this time is significantly different from the blood oxygen value measured previously.

[0083] For another example, the smart watch performs a wearing detection in response to the user pressing the crown (for example, pressing the crown three times in succession) and displays the wearing result in the interface.

[0084] For another example, the smart watch performs a wearing detection in response to the user rotating the crown (for example, rotating the crown 2 circles) and displays the wearing result in the interface.

[0085] Optionally, in some embodiments, when the smart watch determines that the wearer is too tight or too loose, the smart watch can also output adjustment prompt information, which is used to prompt the user how to make adjustments. The adjustment prompt information can be displayed on the same interface as the wearing detection result, or on a different interface.

[0086] In the embodiment of the present application, there is no limitation on the manner in which the smart watch outputs the adjustment prompt information, and several possible implementation methods are introduced as examples below.

[0087] In one possible implementation, the smart watch displays adjustment prompt information on the interface. The adjustment prompt information may be in text form or in animation form, which is not limited in the embodiment of the present application.

[0088] For example, in addition to displaying the detection results on interface 206, the smart watch can also display an adjustment prompt message: "Please tighten the strap" (not shown in the figure).

[0089] For another example, in addition to displaying the test results on interface 206, the smart watch can also display an adjustment prompt message: "Please loosen the buckle by one tooth" (not shown in the figure).

[0090] It should be understood that the description of adjusting the wearing tightness through the buckle can be referred to below and will not be elaborated here.

[0091] In a possible implementation, the smartwatch plays the adjustment prompt message in the form of audio.

[0092] In the embodiments of the present application, the smartwatch can detect whether the user wears it properly. When it is determined that the user wears it too tightly or too loosely, it can output an adjustment prompt message to prompt the user on how to adjust, thereby ensuring the accuracy of functions such as blood pressure measurement, heart rate measurement, and blood oxygen measurement, and helping to improve the user experience.

[0093] Optionally, in some embodiments, the smartwatch can also display the re-wearing detection control 207 and / or the re-blood pressure measurement control 208 on the interface 206.

[0094] The above describes the wearing detection method provided by the embodiments of the present application in combination with the GUI. The following will Figures 3 - 7 introduce the wearing detection method provided by the embodiments of the present application.

[0095] Figure 3 FIG. shows the structural schematic diagram of the wearable device provided by the embodiments of the present application.

[0096] As Figure 3 shown, the wearable device includes a processor, a driving circuit, a pressure sensor #1, a pressure sensor #2, an air pump, and an airbag. Among them, the pressure sensor #1 is used to measure the air pressure in the airbag. The pressure sensor #1, the air pump, and the airbag can be used to implement the blood pressure detection function. The processor of the wearable device can drive the airbag to inflate the airbag through the driving circuit. The pressure sensor #1 is connected to the airbag through an air path and is electrically connected to the processor, and is used to detect the air pressure of the airbag. The processor can obtain the air pressure value measured by the pressure sensor #1, and then the wearable device determines the user's blood pressure according to the air pressure value measured by the pressure sensor #1. The wearable device also includes a pressure sensor #2, which is electrically connected to the processor and is used to measure the air pressure before the gas enters the airbag. Then the wearable device determines the wearing detection result according to the air pressure before the gas enters the airbag.

[0097] In the embodiments of the present application, there is no limitation on the specific position of the pressure sensor #2. The pressure sensor #2 can be set at any position on the air flow path where the gas flows from the outside into the airbag. In some embodiments, the pressure sensor #2 can be set on the main board.

[0098] In the embodiments of the present application, the wearing detection result can be determined through the air pressure value measured by the pressure sensor #2. The following will be combined with Figure 4 for introduction.

[0099] Figure 4The schematic flowchart of the wearing detection method provided by the embodiments of the present application is shown. As Figure 4 shown, the method includes:

[0100] S401, when it is detected that a preset condition is satisfied, gas is filled into the airbag.

[0101] Specifically, the wearable device can fill gas into the airbag when it detects that the preset condition is satisfied.

[0102] In some embodiments, detecting that the preset condition is satisfied means: detecting an operation by the user to trigger wearing detection.

[0103] For example, detecting that the user clicks the icon corresponding to the wearing detection function.

[0104] For another example, detecting an operation where the user continuously presses the crown 3 times.

[0105] For another example, detecting an operation where the user rotates the crown 2 turns.

[0106] For another example, detecting a preset gesture of the user, where the preset gesture corresponds to the wearing detection function.

[0107] In some embodiments, detecting that the preset condition is satisfied means: detecting an operation by the user to trigger measuring physiological parameters, where the physiological parameters include one or more of the following: blood pressure, heart rate, blood oxygen.

[0108] For example, as Figure 2 shown, the smart watch detects an operation where the user clicks the icon 202, and the icon 202 corresponds to the blood pressure measurement function.

[0109] In some embodiments, detecting that the preset condition is satisfied means: the difference between the measured physiological parameter value and the average value of the physiological parameter values measured within the first time period is greater than the threshold.

[0110] For example, as Figure 2 shown, when the smart watch detects that the difference between the blood pressure value measured this time and the average value of the blood pressure values measured in the past week is greater than the threshold, wearing detection can be performed.

[0111] S402, during the process of filling gas into the airbag, obtain the air pressure value of the gas sensor #2.

[0112] Specifically, the process of the air pump filling gas into the airbag is a process where gas enters from the outside into the inside of the wearable device through the air inlet and is filled into the airbag. The air pressure sensor #2 in the embodiments of the present application is arranged on the air flow path where the gas flows from the air inlet into the airbag. In other words, the air pressure sensor #2 is used to detect the air pressure value before the gas flows into the airbag. The wearable device can obtain the air pressure value of the air pressure sensor #2.

[0113] S403. Determine the wearing detection result of the wearable device according to the air pressure value of the air pressure sensor #2.

[0114] Specifically, when gas flows through the air pressure sensor #2, it will cause a jump in the measured air pressure value of the air pressure sensor #2. During the process of the air pump inflating the airbag, since the gas is inflated from the outside to the inside, the air pressure sensor #2 is in a low-pressure state, and the measured air pressure value is negative. The greater the gas flow rate, the smaller the air pressure value measured by the air pressure sensor #2. Therefore, the wearable device can determine the wearing detection result based on the air pressure value measured by the air pressure sensor #2.

[0115] It is not difficult to understand that when the user wears the device more loosely, the gas flow rate will be greater, and the air pressure value measured by the air pressure sensor #2 will be smaller. When the user wears the device more tightly, the gas flow rate will be smaller, and the air pressure value measured by the air pressure sensor #2 will be greater. In other words, the wearable device can indirectly know the magnitude of the gas flow rate through the air pressure value measured by the air pressure sensor #2.

[0116] Such as Figure 5 As shown, in some embodiments, when the wearable device determines that the air pressure value of the air pressure sensor #2 is greater than the threshold #1, it determines that the wearing is too tight.

[0117] In some embodiments, when the wearable device determines that the air pressure value of the air pressure sensor #2 is less than or equal to the threshold #1 and greater than or equal to the threshold #2, it determines that the wearing is normal.

[0118] In some embodiments, when the wearable device determines that the air pressure value of the air pressure sensor #2 is less than the threshold #2, it determines that the wearing is too loose.

[0119] In some embodiments, the air pressure value of the air pressure sensor #2 can be the air pressure value measured by the air pressure sensor #2 during the entire inflation process.

[0120] In some embodiments, the air pressure value of the air pressure sensor #2 can be the air pressure value measured after the gas pressure in the airbag is greater than the threshold #3.

[0121] For example, the air pressure value of the air pressure sensor #2 can be the air pressure value measured after the air pressure of the airbag reaches 100 mmHg.

[0122] When the user wears the device normally and wears it too loosely, in the initial stage of inflation, the airbag of the wearable device may not contact the user's skin. Therefore, in the initial stage of inflation, the gas flow rates entering the wearable device in the two cases of normal wear and too-loose wear may be relatively close, so that the air pressure values of the pressure sensor #2 may also be relatively close. Therefore, in order to avoid misjudgment, the air pressure value of the pressure sensor #2 can be obtained after the gas pressure in the airbag is greater than the threshold #3.

[0123] In some embodiments, the air pressure value of the pressure sensor #2 can be the air pressure value measured by the pressure sensor #2 during the time period #1 of the inflation process.

[0124] For example, the air pressure value of the pressure sensor #2 can be the air pressure value measured by the pressure sensor #2 during the time period from the start of inflation to 10 s.

[0125] It can be understood that the wearable device can obtain multiple air pressure values measured by the pressure sensor #2. The wearable device can perform processing such as removing bad values and calculating the mean value on the multiple air pressure values, and then compare them with the threshold to determine the wearing detection result.

[0126] S404, display the first interface, and the first interface includes the wearing detection result.

[0127] Specifically, after the wearable device determines the wearing detection result, it can display the wearing detection result on the first interface.

[0128] For example, as shown in (d) of Figure 2 , the smart watch displays the wearing detection result on the interface 206.

[0129] In the embodiments of the present application, the wearable device can determine whether the wearing is normal by detecting the air pressure before the gas flows into the airbag, which ensures the accuracy of the physiological parameter measurement result and helps to improve the user experience.

[0130] In some embodiments, the wearable device can also set more thresholds, so that the wearable device can more accurately and better judge the degree of being too loose or too tight when it is determined that the wearing is too loose or too tight.

[0131] For example, continue to refer to Figure 5 , in Figure 5On the basis of setting threshold #1 and threshold #2, the wearable device can also set threshold #4 and threshold #5, where threshold #4 is greater than threshold #1 and threshold #5 is less than threshold #2. When the wearable device determines that the air pressure value of the air pressure sensor #2 is greater than threshold #1 and less than threshold #4, it can be determined that the wear is too tight and one buckle is too tight. When the wearable device determines that the air pressure value of the air pressure sensor #2 is greater than threshold #5 and less than threshold #2, it can be determined that the wear is too loose and one buckle is too loose.

[0132] In some embodiments, the wearable device determines the degree of looseness or tightness during the process of being worn too loose or too tight by setting multiple thresholds, and the wearable device can also determine an adjustment prompt message according to the degree of looseness or tightness, and the adjustment prompt message is used to prompt the user how to make adjustments.

[0133] For example, continuing to refer to Figure 5 , in Figure 5 On the basis of setting threshold #1 and threshold #2, the wearable device can also set threshold #4 and threshold #5, where threshold #4 is greater than threshold #1 and threshold #5 is less than threshold #2. When the wearable device determines that the air pressure value of the air pressure sensor #2 is greater than threshold #1 and less than threshold #4, it can be determined that the wear is too tight and one buckle is too tight, and the wearable device can generate an adjustment prompt message #1, and the adjustment prompt message #1 is used to prompt the user to loosen one buckle. When the wearable device determines that the air pressure value of the air pressure sensor #2 is greater than threshold #5 and less than threshold #2, it can be determined that the wear is too loose and one buckle is too loose, and the wearable device can generate an adjustment prompt message #2, and the adjustment prompt message #2 is used to prompt the user to tighten one buckle.

[0134] In the embodiments of the present application, when it is determined that the wear is too tight or too loose, the wearable device can also detect the air pressure before the gas flows into the airbag through the air pressure sensor #2 to judge the degree of tightness or looseness, and then can output an adjustment prompt message according to the degree of tightness and looseness of the wear, which can better prompt the user how to make tightness adjustments and help improve the user experience.

[0135] Figure 6 FIG. shows a schematic structural diagram of another wearable device provided by the embodiments of the present application.

[0136] As Figure 6As shown, the wearable device includes a processor, a driving circuit, a barometric pressure sensor, a heat source, temperature sensor #1, and temperature sensor #2. Among them, the barometric pressure sensor, the air pump, and the airbag can be used to implement the blood pressure detection function. The barometric pressure sensor is pneumatically connected to the airbag and electrically connected to the processor, and is used to detect the air pressure of the airbag. The processor can obtain the air pressure value measured by the barometric pressure sensor, and then the wearable device can determine the user's blood pressure. The wearable device also includes a heat source, temperature sensor #1, and temperature sensor #2. Among them, the heat source is configured to be started when the air pump works. After the air pump is started, gas will be pumped into the interior of the wearable device. Those skilled in the art can set the positions of the heat source, temperature sensor #1, and temperature sensor #2 as needed so that the gas flows through temperature sensor #1, the heat source, and temperature sensor #2 in sequence.

[0137] In some embodiments, the distance between temperature sensor #1 and the heat source is equal to the distance between temperature sensor #2 and the heat source.

[0138] In the absence of air flow and when the heat source is not started, the temperature values of temperature sensor #1 and temperature sensor #2 are the temperature values inside the wearable device, and the temperature values of temperature sensor #1 and temperature sensor #2 are the same. In the absence of air flow and after the heat source is started and starts to heat up, the temperature values of temperature sensor #1 and temperature sensor #2 will increase, and since the distance between temperature sensor #1 and the heat source is equal to the distance between temperature sensor #2 and the heat source, the heat received by temperature sensor #1 and the temperature sensor is the same, so the temperature values of temperature sensor #1 and temperature sensor #2 are still the same. However, when gas enters the interior of the wearable device, since the gas flow path is temperature sensor #1 - heat source - temperature sensor #2, the heat generated by the heat source will move in the direction of temperature sensor #2 under the action of the gas. Therefore, the temperature value of temperature sensor #2 will be higher than the temperature value of temperature sensor #1. Therefore, the magnitude of the gas flow can be indirectly known based on the difference between the temperature values of temperature sensor #1 and temperature sensor #2.

[0139] In the embodiments of the present application, the specific positions of the heat source, temperature sensor #1, and temperature sensor #2 are not limited. The heat source, temperature sensor #1, and temperature sensor #2 can be set at any position on the gas flow path from the outside into the airbag.

[0140] In some embodiments, the heat source, temperature sensor #1, and temperature sensor #2 can be set on the main board.

[0141] In some embodiments, the heat source, temperature sensor #1, and temperature sensor #2 can be integrated into the design of the air pump, that is, a flow monitoring layer is added, so that the air pump has a flow monitoring function.

[0142] In the embodiments of the present application, the wearing detection result can be determined based on the temperature values measured by temperature sensor #1 and temperature sensor #2. The following will be introduced in conjunction with Figure 7 for illustration.

[0143] Figure 7 FIG. shows a schematic flowchart of the wearing detection method provided by the embodiments of the present application. As Figure 7 shown, the method includes:

[0144] S701, when it is detected that a preset condition is met, inflate the airbag with gas and activate the heat source.

[0145] Specifically, the wearable device can inflate the airbag with gas and activate the heat source when it detects that the preset condition is met. After activating the heat source, the heat source starts to generate heat, and the temperature values measured by temperature sensor #1 and temperature sensor #2 will increase.

[0146] It should be understood that the description of the preset condition can refer to the description of the preset condition in the above text. For the sake of brevity, it will not be repeated here.

[0147] S702, during the process of inflating the airbag with gas, obtain the temperature value of temperature sensor #1 and the temperature value of temperature sensor #2.

[0148] Specifically, when the wearable device detects that the preset condition is met, it activates the air pump to inflate the airbag with gas and activates the heat source. During the process of the air pump inflating the airbag with gas, the temperature value measured by temperature sensor #1 and the temperature value measured by temperature sensor #2 can be obtained.

[0149] S703, determine the wearing detection result of the wearable device according to the temperature value of temperature sensor #1 and the temperature value of temperature sensor #2.

[0150] Specifically, after activating the heat source, the heat source generates heat. When gas flows through temperature sensor #1, the heat source, and temperature sensor #2 in sequence from the air inlet, the heat generated by the heat source will be unevenly distributed along the direction of gas flow, and the temperatures measured by the two temperature sensors will be different. The temperature value measured by temperature sensor #2 will be higher than the temperature value measured by temperature sensor #1. The greater the difference between the temperature value of temperature sensor #1 and the temperature value of temperature sensor #2, the greater the gas flow rate, that is, the user is wearing too loosely. On the contrary, the smaller the difference between the temperature value of temperature sensor #1 and the temperature value of temperature sensor #2, the smaller the gas flow rate, that is, the user is wearing too tightly. In other words, the wearable device can indirectly know the size of the gas flow rate through the difference between the temperature value of temperature sensor #1 and the temperature value of temperature sensor #2.

[0151] In some embodiments, the wearable device may calculate the difference between the temperature value of temperature sensor #1 and the temperature value of temperature sensor #2 according to formula (1) to characterize the difference between the temperature value of temperature sensor #1 and the temperature value of temperature sensor #2.

[0152] ΔT1 = T1 - T2 (1)

[0153] Where ΔT1 is the difference between the temperature value of temperature sensor #1 and the temperature value of temperature sensor #2, T1 is the temperature value of temperature sensor #1, and T2 is the temperature value of temperature sensor #2. Since the temperature value of temperature sensor #2 is greater than the temperature value of temperature sensor #1, the ΔT1 calculated by the wearable device is negative. In these embodiments, when ΔT1 is greater than threshold #1, it can be determined that the wearing is too tight. When ΔT1 is less than or equal to threshold #1 and greater than or equal to threshold #2, it can be determined that the wearing is normal. When ΔT1 is less than threshold #2, it can be determined that the wearing is too loose.

[0154] In some embodiments, the wearable device may calculate the difference between the temperature value of temperature sensor #1 and the temperature value of temperature sensor #2 according to formula (2) to characterize the difference between the temperature value of temperature sensor #1 and the temperature value of temperature sensor #2.

[0155] ΔT2 = T2 - T1 (2)

[0156] Where ΔT2 is the difference between the temperature value of temperature sensor #2 and the temperature value of temperature sensor #1. Since the temperature value of temperature sensor #2 is greater than the temperature value of temperature sensor #1, the ΔT2 calculated by the wearable device is positive. In these embodiments, when ΔT2 is less than threshold #3, it can be determined that the wearing is too tight. When ΔT2 is greater than or equal to threshold #3 and less than or equal to threshold #4, it can be determined that the wearing is normal. When ΔT2 is greater than threshold #4, it can be determined that the wearing is too loose.

[0157] In some embodiments, the wearable device may calculate the difference between the temperature value of temperature sensor #1 and the temperature value of temperature sensor #2 according to formula (3) to characterize the difference between the temperature value of temperature sensor #1 and the temperature value of temperature sensor #2.

[0158] ΔT3 = |T1 - T2| (3)

[0159] Where ΔT3 is the absolute value of the difference between the temperature value of temperature sensor #1 and the temperature value of temperature sensor #2. The ΔT3 calculated by the wearable device is positive. In these embodiments, when ΔT3 is less than threshold #3, it can be determined that the wearing is too tight. When ΔT3 is greater than or equal to threshold #3 and less than or equal to threshold #4, it can be determined that the wearing is normal. When ΔT3 is greater than threshold #4, it can be determined that the wearing is too loose.

[0160] In some embodiments, the temperature value of temperature sensor #1 and the temperature value of temperature sensor #2 may be the temperature values measured by temperature sensor #1 and temperature sensor #2 during the entire inflation process.

[0161] In some embodiments, the temperature value of temperature sensor #1 and the temperature value of temperature sensor #2 may be the temperature values measured by temperature sensor #1 and temperature sensor #2 after the gas pressure in the airbag is greater than threshold #5.

[0162] In some embodiments, the temperature value of temperature sensor #1 and the temperature value of temperature sensor #2 may be the temperature values measured by temperature sensor #1 and temperature sensor #2 during time period #1 of the inflation process.

[0163] It can be understood that the wearable device can obtain multiple temperature values measured by temperature sensor #1 and multiple temperature values measured by temperature sensor #2. The wearable device can process the above data, such as removing bad values and calculating the mean value, then perform a difference calculation, and then compare with the threshold to determine the wearing detection result.

[0164] S704, display the first interface, and the first interface includes the wearing detection result.

[0165] For the description of S704, reference can be made to the description of S404. For the sake of brevity, it will not be repeated here.

[0166] In the embodiments of the present application, the wearable device can determine whether the wearing is normal by detecting the difference in the temperatures measured by two temperature sensors before the gas flows into the airbag, which ensures the accuracy of the physiological parameter measurement result and helps to improve the user experience.

[0167] In some embodiments, the wearable device can also set more thresholds, so that the wearable device can more accurately and better determine the degree of looseness or tightness when it is determined that the wearing is too loose or too tight.

[0168] For example, on the basis of threshold #1 and threshold #2 involved in formula (1), the wearable device can also set threshold #6 and threshold #7, where threshold #6 is greater than threshold #1 and threshold #7 is less than threshold #2. When the wearable device determines that ΔT1 is greater than threshold #1 and less than threshold #6, it can be determined that the wearing is too tight and one buckle is too tight. When the wearable device determines that ΔT1 is greater than threshold #7 and less than threshold #2, it can be determined that the wearing is too loose and one buckle is too loose.

[0169] In some embodiments, the wearable device determines the degree of looseness or tightness during the process of being worn too loosely or too tightly by setting multiple thresholds. Then, the wearable device can also determine an adjustment prompt message according to the degree of looseness or tightness, and this adjustment prompt message is used to prompt the user on how to make adjustments.

[0170] In the embodiments of the present application, when determining that it is worn too tightly or too loosely, the wearable device can also detect the temperature difference between the temperature values of two temperature sensors before the gas flows into the airbag to judge the degree of tightness or looseness. Furthermore, it can output an adjustment prompt message according to the degrees of tightness and looseness, which can better prompt the user on how to adjust the tightness and looseness, and is helpful for improving the user experience.

[0171] It should be noted that in the embodiments of the present application, only the temperature difference between the temperature value of temperature sensor #1 and the temperature value of temperature sensor #2 is used as an example to characterize the difference between the two temperature values. However, the embodiments of the present application are not limited to this. In some other embodiments of the present application, it can also be other parameters used to characterize the temperature difference between the two. For example, the difference between the temperature value of temperature sensor #1 and the temperature value of temperature sensor #2 can be characterized by the square of the difference. For another example, a reference temperature value is set, and the absolute value #1 of the difference between the temperature value of temperature sensor #1 and the temperature reference value, and the absolute value #2 of the difference between the temperature value of temperature sensor #2 and the temperature reference value are calculated respectively. Then, the sum of absolute value #1 and absolute value #2 is used to characterize the difference between the two temperature values. It can be understood that the greater the sum of absolute value #1 and absolute value #2, the greater the difference between the two temperature values; the smaller the sum of absolute value #1 and absolute value #2, the smaller the difference between the two temperature values.

[0172] The above mainly introduces a wearing detection method provided by the embodiments of the present application from the perspective of the wearable device. It can be understood that in order for the wearable device to implement the above functions, it includes the corresponding hardware structures and / or software modules for executing each function. Those skilled in the art should easily realize that, in combination with the algorithm steps of each example described in the embodiments disclosed herein, the present application can be implemented in the form of hardware or a combination of hardware and computer software. Whether a certain function is executed in the way of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Professional technicians can use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of the present application.

[0173] In the case of dividing each function into corresponding function modules (or units), the wearable device provided by the embodiments of the present application includes: a processing module, a detection module, and a display module.

[0174] A processing module, configured to inflate the airbag when it is determined that a preset condition is met.

[0175] A detection module, configured to detect the air pressure value of the pressure sensor #2.

[0176] The processing module is further configured to determine a wearing detection result of the wearable device according to the air pressure value of the pressure sensor #2.

[0177] A display module, configured to display a first interface, and the first interface includes the wearing detection result.

[0178] In some other embodiments, the detection module is configured to detect the temperature value of the temperature sensor #1 and the temperature value of the temperature sensor #2.

[0179] The processing module is further configured to determine a wearing detection result of the wearable device according to the temperature value of the temperature sensor #1 and the temperature value of the temperature sensor #2.

[0180] It should be understood that the implementation principles and technical effects of each module are similar to those of the relevant embodiments of the above method, and will not be elaborated here.

[0181] The wearable device provided in the embodiments of the present application includes a processor, a memory, a blood pressure detection component, and a sensor module. The sensor module includes one or more sensors for implementing the relevant embodiments of the above method. The processor, the memory, the blood pressure detection component, and the sensor module communicate with each other through an internal connection path to transmit control and / or data signals. In a possible design, the processor and the memory can be implemented by a chip. The processor and the memory can be implemented in the same chip, or may be implemented in different chips respectively, or any two of the functions can be combined in one chip. The memory can store program codes, and the processor calls the program codes stored in the memory, so that the wearable device implements the technical solutions in the above embodiments.

[0182] When the wearable device determines that the wearing is too tight or too loose, it can prompt the user to make adjustments. In some scenarios, since the distance between the two watch buckles on the watch band is relatively large, the user may not be able to adjust to a suitable tightness by adjusting the watch buckle. For example, when the wearable device detects that the user is wearing too tightly, it can prompt the user to adjust the tightness. After the user loosens one watch buckle, the wearable device may detect that the user is wearing too loosely again. Therefore, the embodiments of the present application further provide an adjustment mechanism that can finely adjust the tightness.

[0183] In the embodiments of the present application, the same reference numeral is used to represent the same component or the same part. For the same parts in the embodiments of the present application, only one of the parts or components may be marked with a reference numeral in the figure. It should be understood that the reference numeral is equally applicable to other identical parts or components. In addition, the various parts in the drawings are not drawn to scale, and the dimensions and sizes of the parts shown in the drawings are only exemplary and should not be construed as a limitation of the present application.

[0184] The embodiments of the present application define the coordinate system of the drawings. The x-axis direction, the y-axis direction, and the z-axis direction are perpendicular to each other in pairs. The x-axis direction can be understood as the width direction of the adjustment mechanism, the y-axis direction can be understood as the thickness direction of the adjustment mechanism, and the z-axis direction can be understood as the length direction of the adjustment mechanism; alternatively, the z-axis direction can also be understood as the width direction of the adjustment mechanism, and the x-axis direction can be understood as the length direction of the adjustment mechanism. It can be understood that for the convenience of description, in the embodiments of the present application, the x-axis direction is taken as an example to be the width direction of the adjustment mechanism, and the z-axis direction is taken as an example to be the length direction of the adjustment mechanism. It can also be understood that for the convenience of description, in the embodiments of the present application, the positive direction of the z-axis is the first direction, the negative direction of the z-axis is the second direction, and the positive direction of the y-axis is the third direction. Among them, the first direction and the second direction can also be referred to as the length direction of the watch band.

[0185] The following Figures 8 to 12 will introduce the adjustment mechanism provided by the embodiments of the present application in detail.

[0186] Figure 8 The following shows the overall schematic diagram of the adjustment mechanism provided by the embodiments of the present application. Figure 9 The following shows the overall schematic diagram of the adjustment mechanism provided by the embodiments of the present application and the internal schematic diagram of a partial area.

[0187] Referring to Figure 8 and Figure 9 the adjustment mechanism 800 shown, this adjustment mechanism 800 is used to connect the first watch band 900 and the second watch band 1000. Through the cooperation of the various components in the adjustment mechanism 800, the adjustment mechanism 800 can drive the first watch band 900 to move in the length direction of the watch band, thereby achieving the purpose of quickly adjusting the wearing tightness. Among them, when the adjustment mechanism 800 drives the first watch band 900 to move in the length direction of the watch band to achieve loosening, it can be said that the first watch band 900 moves in the first direction, that is, the positive direction of the z-axis in the figure. When the adjustment mechanism 800 drives the first watch band 900 to move in the length direction of the watch band to achieve tightening, it can be said that the first watch band 900 moves in the second direction, that is, the negative direction of the z-axis in the figure.

[0188] Continuing to refer to Figure 8 and Figure 9, the adjusting mechanism 800 includes a housing 810, a fine-tuning slider 820, an adjusting button 830, a connecting component 840, a first elastic component 850, and a second elastic component 860. Among them, the housing 810 can form an integral structure with an accommodation space inside, and the accommodation space opens in a first direction. The housing 810 includes a one-way guide rail 8101 and an opening 8102. The adjusting button 830 includes sliding teeth 8301. The fine-tuning slider 820 is used to connect to the first watch band 900, and the connecting component 840 is used to connect to the second watch band 1000.

[0189] In the embodiments of the present application, the connection method between the fine-tuning slider 820 and the first watch band 900, and the connection method between the connecting component 840 and the second watch band 1000 are not specifically limited. For example, in some embodiments, the first end of the fine-tuning slider 820 is connected to the first watch band 900, and the second watch band 1000 passes through the connecting component 840 and is connected to the connecting component 840. In other embodiments, the adjusting mechanism 800 can also connect the first watch band 900 and the second watch band 1000 in other ways, so that through the adjusting mechanism 800, the first watch band 900 and the second watch band 1000 move relative to each other to achieve the purpose of adjusting the tightness.

[0190] It should be noted that Figure 8 and Figure 9 take the connecting component 840 as a butterfly buckle for example, but the embodiments of the present application do not specifically limit this, and the connecting component 840 can also be a pin buckle, a hook buckle, etc.

[0191] Continuing to refer to Figure 9 in (a) and (b) thereof, where Figure 9 in (b) is Figure 9 a screenshot of the 1-1 position of (a) thereof. The housing 810 can include an upper surface and a lower surface. When the user wears the wearable device, the lower surface is closer to the user's skin. The housing 810 can also include an outer surface and an inner surface. The one-way guide rail 8101 is provided on the inner surface of the housing 810, and the direction of the one-way guide rail is the second direction, and the direction of the opening 8102 is the third direction. The adjusting button 830 passes through the opening 8102 and is connected to the fine-tuning slider 820 through the first elastic component 850. Under the supporting action of the first elastic component 850, the sliding teeth 8301 of the adjusting button 830 are engaged with the one-way guide rail 8101. Among them, the opening 8102 penetrates the outer surface and the inner surface of the housing 810. The third direction can also be described as the direction from the inner surface to the outer surface and perpendicular to the first direction and the second direction, or the direction from the lower surface to the upper surface and perpendicular to the first direction and the second direction, that is, the positive direction of the y-axis in the figure.

[0192] Since the sawteeth on the unidirectional guide rail 8101 have a directionality and the direction is the second direction, when the sliding teeth 8301 of the adjustment button 830 engage with the unidirectional guide rail 8101, the adjustment button 830 can drive the fine-tuning slider 820 to slide relatively in the second direction.

[0193] Of course, when the sliding teeth 8301 of the adjustment button 830 disengage from the unidirectional guide rail 8101, the adjustment button 830 can also drive the fine-tuning slider 820 to slide relatively in the second direction.

[0194] In some embodiments, the fine-tuning slider 820 is further provided with a groove 8201, the adjustment button 830 passes through the opening 8102 and is inserted into the groove 8201, and the first elastic component 850 abuts against the adjustment button 830 and the groove 8201.

[0195] In some embodiments, the fine-tuning slider 820 and the adjustment button 830 abut against the first elastic component 850.

[0196] In some embodiments, the portions of the fine-tuning slider 820 and / or the adjustment button 830 that are in contact with the first elastic component 850 can be fixedly connected by means such as adhesives and buckles.

[0197] In some embodiments, when the first elastic component 850 is in the first state, the user cannot drive the fine-tuning slider 820 to slide in the first direction by pushing the adjustment button 830. For example, when the first elastic component 850 supports the adjustment button 830 so that the sliding teeth 8301 engage with the unidirectional guide rail 8101, the first elastic component 850 is in the first state.

[0198] The first elastic component 850 being in the first state can be divided into two possible implementation manners.

[0199] One possible implementation manner is that the first state is the normal state, that is, the first elastic component 850 does not deform.

[0200] One possible implementation manner is that the first state is the first compression state, that is, although the first elastic component 850 has deformed to a certain extent, it can still support the adjustment button 830 so that the sliding teeth 8301 engage with the unidirectional guide rail 8101.

[0201] Continue to refer to Figure 9 in (c) and (d), where Figure 9 in (c) is Figure 9Screenshot of the 2-2 position in (a) thereof. The second elastic component 860 is disposed in the accommodation space of the housing 810, and when the fine-tuning slider 830 slides in the second direction, or when the sliding tooth 8301 meshes with a non-last sawtooth distributed in the first direction on the one-way guide rail 8101, the second elastic component 860 will be compressed, that is, the second elastic component 860 is in a compressed state. For the description of the state of the second elastic component 860 when the sliding tooth 8301 meshes with the last sawtooth distributed in the first direction on the one-way guide rail 8101, reference can be made to the following text, and it will not be elaborated here.

[0202] It can be understood that when the sliding tooth 8301 meshes with the one-way guide rail 8101, since the sawteeth on the one-way guide rail 8101 have a directionality and the direction is the second direction, even if the second elastic component 860 will push the fine-tuning slider 820 in the first direction, or the user pushes the adjustment button 820 in the first direction, however, the one-way guide rail 8101 and the sliding tooth 8301 of the adjustment button 830 are meshed, and the adjustment button 830 is connected to the fine-tuning slider 820, then it will prevent the fine-tuning slider 820 from sliding in the first direction. In other words, the meshing of the sliding tooth 8301 with the one-way guide rail 8101 can also be understood as the locking of the sliding tooth 8301 with the one-way guide rail 8101. In the case where the sliding tooth 8301 is locked with the one-way guide rail 8101, even if the fine-tuning slider 820 receives a force in the first direction, due to the blocking effect of the sawteeth on the one-way guide rail 8101, the fine-tuning slider 820 will not slide in the first direction. On the contrary, even in the case where the sliding tooth 8301 is locked with the one-way guide rail 8101, when the fine-tuning slider 820 receives a force in the second direction, since the direction of the one-way guide rail 8101 is the second direction, the fine-tuning slider 820 can slide in the second direction.

[0203] In some embodiments, when the first elastic component 850 is in the second state, the user can drive the fine-tuning slider 820 to slide in the first direction by pushing the adjustment button 830.

[0204] For example, continue to refer to Figure 9 in (e) of Figure 9 where (e) in Figure 9 is a screenshot of the 1-1 position of (a) in

[0205] It can be understood that the degree of compression of the first state of the first elastic component is less than that of the second state.

[0206] Continue to refer Figure 9 In (e)-(g) of the figure, when the sliding teeth 8301 are disengaged from the saw teeth on the one-way guide rail 8101, that is, when the locking state is released, the fine-tuning slider 820 will slide in the first direction under the push of the second elastic component 860 due to the absence of the blocking effect of the saw teeth on the one-way guide rail 8101. When the user releases his hand, the adjustment button 830 moves in the third direction under the push of the first elastic component 850, so that the sliding teeth of the adjustment button 830 are engaged with the saw teeth on the one-way guide rail 8101 again, and under the blocking effect of the saw teeth, the fine-tuning slider no longer slides in the first direction.

[0207] It should be noted that Figure 9 In (e)-(g), the fine-tuning slider 820 slides a sawtooth distance under the push of the second elastic component 860 as an example, but the embodiment of the present application is not limited to this. Figure 9 As shown in (h), the fine-tuning slider 820 can slide a distance of multiple saw teeth at one time under the push of the second elastic component 860.

[0208] In some embodiments, when the sliding tooth 8301 of the adjustment button 830 is engaged with the last sawtooth of the one-way guide rail 8101 in the first direction, the second elastic component 860 is in a normal state, that is, the second elastic component 860 is not deformed. In these embodiments, even if the user presses the adjustment button 830 to disengage the sliding tooth 8301 from the sawtooth on the one-way guide rail 8101, the fine-tuning slider 820 will not slide in the first direction because the second elastic component 860 is in a normal state, thereby ensuring that the fine-tuning slider 820 will not easily detach from the housing 810.

[0209] In some embodiments, when the sliding tooth 8301 of the adjustment button 830 is engaged with the last sawtooth of the one-way guide rail 8101 in the first direction, the second elastic component 860 is still in a compressed state. In these embodiments, when the user presses the adjustment button 830 to disengage the sliding tooth 8301 from the sawtooth on the one-way guide rail 8101, the fine-tuning slider 820 will still slide in the first direction due to the push of the second elastic component 860.

[0210] Exemplarily, the first elastic component 850 and the second elastic component 860 may be springs, and the first elastic component 850 and the second elastic component 860 may also be other components capable of elastic deformation, which is not limited in the present application.

[0211] In some embodiments, the working loads of the first elastic component 850 and the second elastic component 860 are the same.

[0212] In some embodiments, the working loads of the first elastic component 850 and the second elastic component 860 are different.

[0213] In some embodiments, the working loads of the first elastic component 850 and the second elastic component 860 are between 2N and 10N.

[0214] In summary, the usage method of the adjusting mechanism 800 provided by the embodiments of the present application is as follows: When the user wears the wearable device on the wrist or upper arm, etc., when the user feels that the wearing is loose, or the wearable device detects that the wearing is loose, the user can push the adjustment button 830 in the second direction. The adjustment button 830 can drive the fine adjustment slider 820 to slide in the second direction. Since the fine adjustment slider 820 is connected to the first watch band 900, it also drives the first watch band 900 to move in the second direction, thereby achieving the purpose of tightening. It can be understood that when the user tightens, there is no need to press the adjustment button 830.

[0215] When the user feels that the wearing is tight, or the wearable device detects that the wearing is tight, the user can press the adjustment button 830 so that the sliding teeth 8301 on the adjustment button 830 are disengaged from the saw teeth on the one-way guide rail 8101. Under the push of the second elastic component 860, the fine adjustment slider 820 slides in the first direction, thereby achieving the purpose of loosening. When the user determines that the adjustment is appropriate, the user can stop pressing the adjustment button 830. Then, the adjustment button 830 will move in the third direction under the push of the first elastic component 850, so that the sliding teeth 8301 are engaged with the saw teeth on the one-way guide rail 8101 again. Under the block of the saw teeth, it can block the fine adjustment slider 820 from sliding in the first direction, thereby achieving the purpose of locking. It can be understood that since the fine adjustment slider 820 can slide in the first direction under the push of the second elastic component 860, the user can operate with only one hand, and the operation is simple.

[0216] It should be noted that in the above introduction, the direction of the one-way guide rail 8101 is the second direction. In some other embodiments, the direction of the one-way guide rail 8101 can also be the first direction.

[0217] It can be understood that when the direction of the one-way guide rail 8101 is the first direction, the position of the second elastic component 860 can be adjusted synchronously so that when the fine adjustment slider 820 slides in the first direction, the second elastic component 860 will be compressed.

[0218] It can also be understood that the direction of the one-way guide rail 8101 is the first direction. When the sliding teeth 8301 are engaged with the one-way guide rail 8101, the user can push the adjustment button 830 in the first direction. The adjustment button 830 can drive the fine adjustment slider 820 to slide in the first direction. Since the fine adjustment slider 820 is connected to the first watch band 900, it also drives the first watch band 900 to move in the first direction, thereby achieving the purpose of loosening.

[0219] When the user feels that the wearing is tight, or the wearable device detects that the wearing is tight, the user can press the adjustment button 830 so that the sliding teeth 8301 on the adjustment button 830 disengage from the saw teeth on the one-way guide rail 8101. Under the push of the second elastic component 860, the fine-tuning slider 820 slides in the second direction, thus achieving the purpose of tightening.

[0220] The following will Figures 10 to 12 introduce each component of the adjustment mechanism 800 in detail.

[0221] Figure 10 The figure shows an overall schematic diagram of the housing 810 provided by the embodiment of the present application.

[0222] Referring to Figure 10 , the housing 810 may include an upper housing and a bottom plate (not shown in the figure). The one-way guide rail 8101 and the opening 8102 are provided on the upper housing. The one-way guide rail 8101 may be provided on the inner surface of the upper housing.

[0223] In some embodiments, the upper housing and the one-way guide rail 8101 are integrally formed. Alternatively, in some other embodiments, the one-way guide rail 8101 is an independent component and is connected to the inner surface of the upper housing by means of bonding or the like.

[0224] In some embodiments, the caliber of the opening 8102 near the outer surface of the upper housing is larger than the caliber of the opening 8102 near the inner surface of the upper housing.

[0225] In the embodiment of the present application, the opening 8102 has a variable caliber and the caliber near the outer surface of the upper housing is larger, which can give the user a larger operating space, facilitate the user's better operation, and help improve the user experience.

[0226] Alternatively, in some other embodiments, the caliber of the opening 8102 near the outer surface of the upper housing may also be equal to the caliber of the opening 8102 near the inner surface of the upper housing.

[0227] In some embodiments, the length of the opening 8102 in the first direction is greater than or equal to the length of the one-way guide rail 8101 in the first direction.

[0228] Regarding the length of the opening 8102 in the first direction being greater than or equal to the length of the one-way guide rail 8101 in the first direction, the following three possible implementation manners may be included.

[0229] One possible implementation manner: The lengths of the caliber of the opening 8102 near the outer surface of the upper housing and the caliber of the opening 8102 near the inner surface of the upper housing in the first direction are both greater than the length of the one-way guide rail 8101 in the first direction.

[0230] A possible implementation: The length of the opening 8102 near the outer surface of the upper housing in the first direction is greater than the length of the one-way guide rail 8101 in the first direction, and the length of the opening 8102 near the inner surface of the upper housing in the first direction is equal to the length of the one-way guide rail 8101 in the first direction.

[0231] A possible implementation: The lengths of the opening 8102 near the outer surface of the upper housing and the opening 8102 near the inner surface of the upper housing in the first direction are both equal to the length of the one-way guide rail 8101 in the first direction.

[0232] In the embodiments of the present application, the connection manner between the upper housing and the bottom plate is not specifically limited. Hereinafter, several possible implementation manners will be exemplarily introduced.

[0233] In some embodiments, one side of the upper housing close to the bottom plate includes a chute 8103 and a positioning screw hole 8104. The upper housing and the bottom plate are connected through the chute 8103 and fixedly connected through a screw.

[0234] After the upper housing and the bottom plate are connected through the chute 8103, since the chute 8103 already provides a certain supporting effect, the upper housing does not need to be provided with positioning screw holes 8104 on all four sides. Only the positioning screw holes 8104 are arranged on both sides of the end far from the first watch band 900 and fixedly connected through a screw. When the upper housing and the bottom plate are fixedly connected, a screw is used, and the screw has no head, so the overall thickness of the adjusting mechanism 800 at the end far from the first watch band can be reduced.

[0235] In some embodiments, positioning screw holes 8104 are distributed around the upper housing, and the upper housing and the bottom plate are fixedly connected through a plurality of bolts.

[0236] In some embodiments, the upper housing and the bottom plate are bonded.

[0237] In some other embodiments, the upper housing and the bottom plate of the housing 810 may also be integrally formed.

[0238] In some embodiments, the length of the one-way guide rail 8101 in the first direction is equal to the distance between two adjacent pin holes on the watch band.

[0239] In the embodiments of the present application, the length of the one-way guide rail 8101 of the adjusting mechanism 800 in the first direction is equal to the distance between two adjacent pin holes on the watch band, so that when the tightness is adjusted, an adjustment with a smaller amplitude can be achieved, the adjustment accuracy is improved, and the user experience is helped to be enhanced.

[0240] It can be understood that, in the embodiments of the present application, only the example where the length of the one-way guide rail 8101 in the first direction is equal to the distance between two adjacent pinholes on the watch band is taken, but no specific limitation is made thereto. In some other embodiments, the length of the one-way guide rail 8101 in the first direction may be equal to the distance between three adjacent pinholes on the watch band. For example, the watch band includes pinhole #1, pinhole #2, and pinhole #3, where pinhole #1 is adjacent to pinhole #2, and pinhole #2 is adjacent to pinhole #3. The length of the one-way guide rail 8101 in the first direction may be equal to the distance between pinhole #1 and pinhole #3.

[0241] In some embodiments, the length of the one-way guide rail 8101 in the third direction is 0.3 - 0.6 mm, that is, the length of the sawteeth on the one-way guide rail 810 in the third direction is 0.3 - 0.6 mm. The length of the one-way guide rail 8101 in the third direction can also be understood as the height of the one-way guide rail 8101, that is, the height of the sawteeth.

[0242] In some embodiments, the length of each sawtooth of the one-way guide rail 8101 in the first direction is 0.8 - 1.2 mm.

[0243] Figure 11 The figure shows an overall schematic diagram of the fine-tuning slider 820 provided by the embodiments of the present application.

[0244] Reference Figure 11 , the second elastic component 860 can be arranged on both sides of the fine-tuning slider 820 along the x direction. The first end 8202 of the fine-tuning slider 820 is used to connect to the first watch band 900. In the embodiments of the present application, no limitation is made on the connection manner between the fine-tuning slider 820 and the first watch band 900.

[0245] For example, referring to Figure 11 in (a), a pinhole is provided at the first end 8202 of the fine-tuning slider 820, and the fine-tuning slider 820 is connected to the first watch band rotating shaft through this pinhole.

[0246] For another example, referring to Figure 11 in (b), a groove is provided at the first end 8202 of the fine-tuning slider 820, and the first watch band 900 can be inserted into this groove, and the fine-tuning slider 820 is fixedly connected to the first watch band 900 through bolts.

[0247] Figure 12 The figure shows an overall schematic diagram of the adjustment button 830 provided by the embodiments of the present application.

[0248] Reference Figure 12 , the adjustment button 830 includes a sliding tooth 8301, and the size of this sliding tooth 8301 matches the size of the sawteeth on the one-way guide rail 8101.

[0249] In some embodiments, the adjustment button 830 further includes a platform 8302, where the sliding teeth 8301 are arranged on the platform 8302.

[0250] In some embodiments, the length of the platform 8302 in the first direction is greater than the length of the sliding teeth 8301 in the first direction.

[0251] In the embodiments of the present application, sliding teeth 8301 can be arranged on the platform 8302 of the adjustment button 830 to engage with the sawteeth on the one-way guide rail 8101. In addition, the length of the platform 8302 in the first direction is greater than the length of the sliding teeth 8301 in the first direction, thereby increasing the overall length of the adjustment button 830 in the first direction, increasing the contact area with the user's finger, and enabling the user to operate better, which helps to improve the user experience.

[0252] Among them, the sliding teeth 8301 can be regarded as a slope. As Figure 9 and 12 shown, the sliding teeth 8301 include a long slope and a short slope. The angle between the long slope and the first direction is an acute angle, the angle between the short slope and the first direction is an obtuse angle, the angle between the long slope and the second direction is an obtuse angle, the angle between the short slope and the second direction is an acute angle, and the angle between the long slope and the first direction is less than the angle between the short slope and the second direction. Therefore, when the sliding teeth 8301 engage with the sawteeth on the one-way guide rail 8101, even if the fine-tuning slider 820 is subjected to a force in the first direction, due to the contact between the short slope and the sawteeth on the one-way guide rail 8101, the fine-tuning slider 820 will be blocked from sliding in the first direction.

[0253] It should be noted that in the embodiments of the present application, only the case where the sliding teeth 8301 include a long slope and a short slope is taken as an example, but the present application does not make specific limitations in this regard. In other embodiments of the present application, the sliding teeth 8301 may only include one slope, and the angle between the slope and the first direction is an acute angle, and the angle between the slope and the second direction is an obtuse angle.

[0254] It should also be noted that Figure 9 and Figure 12 the number of the sliding teeth 8301 on the adjustment button 830 is 1, but the present application does not make specific limitations in this regard. In other embodiments of the present application, the number of the sliding teeth 8301 on the adjustment button 830 may be multiple.
