Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of computers, and particularly relates to a control method of a connecting band of a wearable device and related equipment. BACKGROUND

[0002] A wearable device such as a watch, a bracelet, a virtual reality (VR) device or an augmented reality (AR) device needs to be worn on a user's body, and the tightness of the wearable device when worn needs to be adjusted by the user due to different body shapes of different users.

[0003] Specifically, the wearable device is provided with a connecting band, when the user manually controls the connecting band to perform a contraction operation, the wearable device worn can be tightened, and when the user manually controls the connecting band to perform an extension operation, the wearable device worn can be loosened, and a scheme for automatically controlling the connecting band to perform the contraction operation or the extension operation is urgently needed. SUMMARY

[0004] Embodiments of the present application provide a control method of a connecting band of a wearable device and related equipment, which provide a scheme for automatically controlling the connecting band to perform the contraction operation or the extension operation, since the first power source and the second power source are located at two ends of the roller, the roller can be synchronously driven to rotate in the target direction, that is, balanced traction is provided at two ends of the roller, which is beneficial to ensure that the connecting band is subjected to balanced traction, is beneficial to reduce the wear of the connecting band, and prolongs the use time of the connecting band.

[0005] To solve the above technical problems, embodiments of the present application provide the following technical solutions:

[0006] In a first aspect, the embodiments of the present application provide a wearable device, which can be used in the field of smart wearable devices. The wearable device comprises a device main body, a connecting band and an adjusting device. The connecting band is connected to the device main body. The adjusting device comprises two power sources, two transmission assemblies and a roller shaft. The two power sources comprise a first power source and a second power source. The two transmission assemblies comprise a first transmission assembly and a second transmission assembly. The first power source is connected to the first end of the roller shaft through the first transmission assembly. The second power source is connected to the second end of the roller shaft through the second transmission assembly. The first end and the second end are two ends of the roller shaft. The rotation shaft of the first power source is perpendicular to the rotation shaft of the roller shaft. The rotation shaft of the second power source is perpendicular to the rotation shaft of the roller shaft. The first transmission assembly is used to drive the roller shaft to rotate in a target direction by transmitting the driving force output by the first power source to the roller shaft. The second transmission assembly is used to drive the roller shaft to rotate in the target direction by transmitting the driving force output by the second power source to the roller shaft. When the roller shaft rotates in the target direction, the connecting band is driven to move, so as to realize the contraction operation or the stretching operation of the connecting band.

[0007] In the present implementation, the above scheme provides a scheme for automatically controlling the connecting band to perform the contraction operation or the stretching operation. Since the first power source and the second power source are located at two ends of the roller shaft, the roller shaft can be synchronously driven to rotate in the target direction, that is, balanced traction is provided at the two ends of the roller shaft, which is beneficial to ensure that the connecting band receives balanced traction and is beneficial to reduce the wear of the connecting band and prolong the service life of the connecting band.

[0008] In a possible implementation of the first aspect, when the two power sources are working, the first transmission assembly is used to increase the moment of the driving force output by the first power source, and the second transmission assembly is used to increase the moment of the driving force output by the second power source. That is, the driving force obtained by the roller shaft can be greater than the sum of the driving forces output by the first power source and the second power source, so as to provide greater driving force for the connecting band.

[0009] In the embodiments of the present application, when the user is in a running state or the like, the power source can need to provide greater traction. After the first transmission assembly and the second transmission assembly amplify the torque of the driving force output by the power source, the roller will obtain greater driving force, so that the roller can provide greater traction to the connecting belt. Therefore, the power source can provide sufficient power to support the connecting belt to perform contraction or expansion operation in more scenarios, which is beneficial to expand the application scenarios of the present scheme. In addition, when the first power source and the second power source are not working, the connecting belt can be subjected to external traction. The traction received by the connecting belt can be conducted to the first power source through the roller and the first transmission assembly, and the traction received by the connecting belt can also be conducted to the second power source through the roller and the second transmission assembly 305. The first transmission assembly is also used to reduce the traction conducted to the first power source 302, and the second transmission assembly can also be used to reduce the traction conducted to the second power source. Since the smaller traction is lower than the resistance of the first power source (or the second power source) itself, the self-locking of the first power source and the second power source can be achieved. That is, when the user wears the wearable device, the connecting belt will not easily perform contraction or expansion operation, so that the user can comfortably wear the wearable device.

[0010] In a possible implementation form of the first aspect, when the first transmission assembly and the second transmission assembly adopt a gear transmission mode, the first transmission assembly is a first gear set, and the second transmission assembly is a second gear set. The first gear set and the second gear set each include at least one gear. Alternatively, when the first transmission assembly and the second transmission assembly can each adopt a belt transmission mode, the first transmission assembly and the second transmission assembly each can include a driving wheel, a transmission belt, and a driven wheel. The driving wheel of each transmission assembly is connected with the power source. The driving wheel in the transmission assembly and the driven wheel of the transmission assembly are connected through the transmission belt. The driven wheel in the transmission assembly can be connected with one end of the roller.

[0011] In a possible implementation of the first aspect, each of the first gear set and the second gear set comprises at least one first gear, the first gear can comprise N gears coaxial, N is an integer greater than or equal to 2. When N is 2, the first gear can also be referred to as a double gear, when N is 3, the first gear can also be referred to as a triple gear, and the like, and the specific selection of the first gear can be flexibly set according to the actual product form, which is not limited herein. The first gear comprises a first sub-gear and a second sub-gear, the first sub-gear and the second sub-gear are coaxial, the radius of the second sub-gear is smaller than the radius of the first sub-gear, the second sub-gear in the first gear is engaged with the second gear, and the radius of the second gear is greater than the radius of the second sub-gear; when the two power sources are working, the second sub-gear in the first gear set is used to transmit the driving force output by the first power source to the second gear in the first gear set, and the second sub-gear in the first gear set is used to transmit the driving force output by the second power source to the second gear in the first gear set.

[0012] In the embodiments of the present application, a plurality of first gears can be arranged in each transmission assembly, so that the gears with larger radii in the first gears can be engaged with the previous gears, and the gears with smaller radii in the first gears can be engaged with the next gears. Since the driving force is transmitted from the gears with smaller radii to the gears with larger radii, the rotational speed will decrease and the driving force will increase, so that the radius of the gears can be reduced under the condition that the rotational speed is unchanged by the first gears. Moreover, the multi-stage transmission by the plurality of first gears in each transmission assembly is beneficial to increasing the driving force output by the power sources and reducing the radius of the gear connected to the roller, that is, beneficial to reducing the radius of the largest gear in the transmission assembly, thereby reducing the thickness of the entire driving device.

[0013] In a possible implementation of the first aspect, the first power source and the second power source are both electric machines, the rotational shaft of the first power source is parallel to the length direction of the connecting belt, and the rotational shaft of the second power source is parallel to the length direction of the connecting belt; the first gear is a double gear, and the second gear is a gear with a larger radius in the double gear; the target gear is a double gear, the first sub-gear in the target gear is a face gear, the first sub-gear in the target gear is connected to the power source, and the second sub-gear in the target gear is engaged with the next gear in the gear set, wherein the face gear in the target gear is used to change the direction of the driving force output by the power source.

[0014] In a possible implementation of the first aspect, the transmission ratio of the first gear set and the transmission ratio of the second gear set are both located in the target interval, that is, when the two power sources are working, the ratio between the torque obtained by the first end of the roller and the torque output by the first power source is located in the target interval, and the ratio between the torque obtained by the second end of the roller and the torque output by the second power source is located in the target interval, and the target interval is 50 to 100.

[0015] In the embodiments of the present application, the transmission ratio of the first gear set and the transmission ratio of the second gear set are disclosed, which is beneficial to reduce the difficulty of implementation of the present solution.

[0016] In a possible implementation manner of the first aspect, the first gear set and the second gear set each include a target gear, the target gear in the first gear set is configured to change the direction of the driving force output by the first power source, and the target gear in the second gear set is configured to change the direction of the driving force output by the second power source. The first power source and the second power source output a torque in a plane parallel to the connecting belt, the target gear in the first gear set is configured to convert the torque output by the first power source into a torque in a plane perpendicular to the connecting belt, and the target gear in the second gear set is configured to convert the torque output by the second power source into a torque in a plane perpendicular to the connecting belt. The target gear includes any one of the following gears: a face gear, a worm gear, a bevel gear, or a bevel gear.

[0017] In the embodiments of the present application, the first gear set and the second gear set each include a target gear configured to change the direction of the driving force output by the power source, and multiple implementation manners of the target gear are provided, which is beneficial to improve the implementation flexibility of the present solution and expand the application scenarios of the present solution.

[0018] In a possible implementation manner of the first aspect, the rotation axis of the first power source is parallel to the length direction of the connecting belt, and the rotation axis of the second power source is parallel to the length direction of the connecting belt, that is, the rotation axis of the first power source is parallel to the rotation axis of the second power source. Since the rotation axis of the roller is perpendicular to the rotation axis of the first power source (or the second power source), the rotation axis of the roller is parallel to the width direction of the connecting belt. The length direction of the connecting belt can also be referred to as the long side direction of the connecting belt, and the width direction of the connecting belt can also be referred to as the short side direction of the connecting belt.

[0019] In a possible implementation manner of the first aspect, the first power source is fixed to the first side of the connection band, the second power source is fixed to the second side of the connection band, and the adjusting device further includes a first sensor, a second sensor and a driving assembly, the first sensor is fixed to the first side of the connection band, and the second sensor is fixed to the second side of the connection band. It should be noted that, since the first power source and the second power source can be arranged on the outer surface of the connection band, and the first sensor and the second sensor are used to obtain the pressure generated on the connection band by the user, the first sensor and the second sensor can be arranged on the inner surface of the connection band, that is, the first sensor and the first power source can be arranged on two different surfaces of the connection band, and the second sensor and the second power source can be arranged on two different surfaces of the connection band. The outer surface of the connection band and the inner surface of the connection band are two different surfaces of the connection band that are parallel to each other, and when the user wears the wearable device, the surface of the connection band that is close to the skin of the user is referred to as the inner surface of the connection band. The first sensor is used to obtain a first pressure value, and the second sensor is used to obtain a second pressure value. If it is determined according to the first pressure value and the second pressure value that the pressure difference between the first side and the second side of the connection band is greater than or equal to a pressure threshold, the driving assembly can be in the second working mode, and the number of control signals sent by the driving assembly to the first power source and the second power source in the target time period is different, so as to reduce the pressure difference between the first side and the second side, and the rotation speed of the first power source and the second power source is positively correlated with the sending frequency of the control signal.

[0020] In the embodiments of the present application, the first sensor and the second sensor are also used to obtain the pressure difference between the first side and the second side of the connection band, and in the case where it is determined that the pressure difference between the first side and the second side of the connection band is greater than or equal to a pressure threshold, the number of control signals sent to the first power source and the second power source in the target time period is different, so as to reduce the pressure difference between the first side and the second side of the connection band; that is, a feedback mechanism is provided, and the pressure difference between the first side and the second side of the connection band can be adjusted in time, so as to further ensure that the connection band can be subjected to balanced traction, which is beneficial to reducing the wear of the connection band and prolonging the use time of the connection band.

[0021] In a possible implementation manner of the first aspect, the shape of the tooth profile corresponding to the gears included in the first gear set is an axisymmetric figure, and the shape of the tooth profile corresponding to the gears included in the second gear set is an axisymmetric figure. In the embodiment of the application, since the shape of the tooth profile corresponding to the gears included in the transmission assembly is an axisymmetric figure, the meshing between the gears of the transmission assembly can be achieved regardless of whether the gears rotate in a forward direction or a reverse direction, so that good transmission of driving force is achieved, which is beneficial to reducing the wear between the gears and prolonging the service life of the transmission assembly. In addition, when the shape of the tooth profile corresponding to the gears included in the first transmission assembly and the second transmission assembly is an isosceles trapezoid, the noise generated by the two transmission assemblies during operation can be reduced.

[0022] In a possible implementation manner of the first aspect, the adjusting device further includes a driving assembly, the first power source and the second power source are both motors, and in the first working mode, the driving assembly is configured to synchronously send control signals to the first power source and the second power source, that is, the driving assembly can synchronously send a second control signal to the second power source while sending a first control signal to the first power source, to instruct the first power source and the second power source to work synchronously. The synchronous working of the first power source and the second power source means that the first power source and the second power source start to output driving force at the same time, and the first power source and the second power source output driving force of the same size. The control signal is used to instruct the first power source and the second power source to output driving force, and the rotation speed of the first power source and the second power source is positively correlated with the sending frequency of the control signal. It should be noted that, since there is an error in the circuit transmission process of the pulse signal, the time when the first power source obtains the first control signal and the time when the second power source obtains the second control signal can have an error, for example, an interval of 0.5 ms, 1 ms, 2 ms or other time lengths, which are not exhaustively listed here. That is, the time when the first power source obtains the first control signal and the time when the second power source obtains the second control signal can not be exactly consistent.

[0023] In the embodiment of the application, since the first power source and the second power source are both motors, the rotation speed of the first power source and the second power source is positively correlated with the sending frequency of the control signal, so that the driving assembly can adjust the rotation speed of the first power source and the second power source by adjusting the sending frequency of the control signal, thereby adjusting the speed of the connecting belt performing the contraction operation or the stretching operation according to the actual application scenario, which is beneficial to improving the flexibility of the scheme.

[0024] In a possible implementation manner of the first aspect, the wearable device is any one of the following: a watch, a bracelet, a virtual reality (VR) device, an augmented reality (AR) device, earphones or glasses. In the embodiment of the application, multiple specific forms of the wearable device are provided, which is beneficial to expanding the application scenario of the scheme and improving the implementation flexibility of the scheme.

The two transmission assemblies comprise a first transmission assembly and a second transmission assembly. The first power source is connected with a first end of the roller shaft through the first transmission assembly. The second power source is connected with a second end of the roller shaft through the second transmission assembly. The first end and the second end are two ends of the roller shaft respectively. The rotation shaft of the first power source is perpendicular to the rotation shaft of the roller shaft. The rotation shaft of the second power source is perpendicular to the rotation shaft of the roller shaft. The first transmission assembly is used to drive the roller shaft to rotate in a target direction by transmitting the driving force output by the first power source to the roller shaft. The second transmission assembly is used to drive the roller shaft to rotate in the target direction by transmitting the driving force output by the second power source to the roller shaft. The connecting band is driven to move when the roller shaft rotates in the target direction.

[0026] The specific implementation structure of the wearable device assembly provided in the second aspect of the embodiments of the present application can refer to the description in the various possible implementation manners in the first aspect, which will not be described here one by one.

[0027] In a third aspect, the embodiments of the present application provide an adjusting device, which can be applied to the field of smart wearable devices. The adjusting device is arranged on a connecting band of a wearable device. The adjusting device is used to connect with a main body of the wearable device through the connecting band. The adjusting device comprises two power sources, two transmission assemblies and a roller shaft. The two power sources comprise a first power source and a second power source. The two transmission assemblies comprise a first transmission assembly and a second transmission assembly. The first power source is connected with a first end of the roller shaft through the first transmission assembly. The second power source is connected with a second end of the roller shaft through the second transmission assembly. The first end and the second end are two ends of the roller shaft respectively. The rotation shaft of the first power source is perpendicular to the rotation shaft of the roller shaft. The rotation shaft of the second power source is perpendicular to the rotation shaft of the roller shaft. The first transmission assembly is used to drive the roller shaft to rotate in a target direction by transmitting the driving force output by the first power source to the roller shaft. The second transmission assembly is used to drive the roller shaft to rotate in the target direction by transmitting the driving force output by the second power source to the roller shaft. The connecting band is driven to move when the roller shaft rotates in the target direction.

[0028] The specific implementation structure of the adjusting device provided in the third aspect of the embodiments of the present application can refer to the description in the various possible implementation manners in the first aspect, which will not be described here one by one.

[0029] In a fourth aspect, the embodiments of the present application provide a control method of a connecting band of a wearable device, which can be applied to the field of smart wearable devices. The method is applied to a wearable device, which includes a processor, a sensor, a connecting band, and an adjusting device. The adjusting device includes two power sources, two transmission assemblies, and a roller shaft. The two power sources include a first power source and a second power source. The two transmission assemblies include a first transmission assembly and a second transmission assembly. The first power source is connected to the first end of the roller shaft through the first transmission assembly. The second power source is connected to the second end of the roller shaft through the second transmission assembly. The first end and the second end are two ends of the roller shaft. The rotating shaft of the first power source is perpendicular to the rotating shaft of the roller shaft. The rotating shaft of the second power source is perpendicular to the rotating shaft of the roller shaft. The method includes: when the processor determines that a first condition is met according to a measurement value collected by the sensor, synchronously sending a control signal to the first power source and the second power source. The control signal is used to control the first power source and the second power source to output driving force. The first transmission assembly is used to transmit the driving force output by the first power source to the roller shaft in a transmission manner, so as to drive the roller shaft to rotate in a target direction. The second transmission assembly is used to transmit the driving force output by the second power source to the roller shaft in a transmission manner, so as to drive the roller shaft to rotate in the target direction. When the roller shaft rotates in the target direction, the connecting band is driven to move.

[0030] In a possible implementation manner of the fourth aspect, the sensor includes any one or more of the following sensors: a pressure sensor, a temperature sensor, a humidity sensor, an inertial sensor, or an acceleration sensor. Further, if the sensor includes a pressure sensor arranged on the connecting band, the pressure sensor is used to measure the pressure value sensed by the connecting band, that is, the pressure value obtained by the pressure sensor is used to reflect the tightness of the connecting band. When the pressure value obtained by the pressure sensor is within a preset threshold interval, it is considered that the first condition is met.

[0031] If the sensor includes a temperature sensor arranged on the connecting band, when the temperature value obtained by the temperature sensor is greater than or equal to a target temperature value, the connecting band is driven to move to perform the stretching operation. During the process in which the user wears the wearable device, if the temperature sensor finds that the temperature of the user's body surface is too high, the connecting band can be appropriately loosened to reduce the temperature of the user's body surface, so as to provide a more comfortable wearing experience for the user, and help to improve the user stickiness of the present solution.

[0032] If the sensor can include a humidity sensor arranged on the connecting band, when the humidity value obtained by the humidity sensor is greater than or equal to a target humidity value, the driving of the connecting band to perform the stretching operation can be triggered; since in the process of wearing the wearable device by the user, if the humidity of the user's body surface is found to be too high through the humidity sensor, it proves that the user may sweat during wearing, and the connecting band can be appropriately relaxed to reduce the humidity of the user's body surface, thereby providing a more comfortable wearing experience for the user.

[0033] If the sensor can include an inertial sensor or an acceleration sensor, the foregoing inertial sensor or acceleration sensor is used to obtain the current motion state of the wearable device, when it is determined according to the measurement value collected by the inertial sensor that the moving speed of the wearable device is greater than or equal to a target speed value, or when it is determined according to the measurement value collected by the acceleration sensor that the acceleration of the wearable device is greater than or equal to a target acceleration, it is considered that the first condition is met, and the driving of the connecting band to perform the contraction operation can be triggered; since the user will drive the wearable device to move quickly in a fast motion state, the wearable device is prone to centrifugal force, and the driving of the connecting band to perform the contraction operation can be triggered to avoid the wearable device from falling off.

[0034] In a possible implementation manner of the fourth aspect, the processor synchronously sends control signals to the first power source and the second power source, including: in a case where the processor determines that the pressure value obtained by the sensor is located in a first threshold interval, the processor synchronously sends the control signals to the first power source and the second power source at a first frequency; in a case where the processor determines that the pressure value obtained by the sensor is located in a second threshold interval, the processor synchronously sends the control signals to the first power source and the second power source at a second frequency; wherein the pressure value corresponding to the first threshold interval is less than the pressure value corresponding to the second threshold interval, the first frequency is greater than the second frequency, and the rotation speed of the first power source and the second power source is positively correlated with the sending frequency of the control signals.

It should be understood that the terms thus used can be interchanged under appropriate circumstances, and this is merely a distinguishing manner adopted in the description of the embodiments of the present application for the objects with the same attributes in the description. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, so that a process, a method, a system, a product or an apparatus containing a series of units does not have to be limited to those units, but can include other units not clearly listed or inherent to the process, the method, the product or the apparatus.

[0058] The embodiments of the present application are described below with reference to the accompanying drawings. Those skilled in the art can know that, with the development of technology and the emergence of new scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0059] The present application can be applied to various wearable devices that need to adjust the tightness. As an example, for example, the wearable device is a bracelet (or a watch), and the connecting band can be the watchband of the bracelet (or the watch). Since the sizes of wrists of different users are different, the connecting band in the figure needs to be controlled to perform the contraction operation or the expansion operation to adjust the tightness when the user wears the bracelet.

[0060] As another example, refer to Figure 1 a , Figure 1 a is a schematic diagram of a wearable device according to an embodiment of the present application. Figure 1 a In the embodiment, the wearable device is a virtual reality (VR) device, as shown in the figure. Since the sizes of head circumferences of different users are different, the connecting band in the figure needs to be controlled to perform the contraction operation or the expansion operation to adjust the tightness when the user wears the VR device.

[0061] As another example, refer to Figure 1 b , Figure 1 b is a schematic diagram of a wearable device according to an embodiment of the present application. Figure 1 b In the embodiment, the wearable device is a headset, as shown in the figure. Since the sizes of heads of different users are different, the connecting band in the figure needs to be controlled to perform the contraction operation or the expansion operation to adjust the tightness when the user wears the headset.

It should be noted that the above are only examples for facilitating the understanding of the solutions, and the embodiments of the present application can also be applied to other types of wearable devices, such as augmented reality (AR) devices or other types of wearable devices, and so on. Here, the examples are not exhaustive, and in subsequent embodiments, only the wearable device is taken as an example of a watch or a bracelet to further illustrate the structure of the wearable device. In the embodiments of the present application, various specific forms of the wearable device are provided, which is beneficial to expand the application scenarios of the solutions and improve the implementation flexibility of the solutions.

[0064] In combination with the above description, the embodiment of the present application provides a wearable device. Please refer to Figure 2 and Figure 3 , Figure 2 FIG. 1 is a structural schematic diagram of a wearable device provided by the embodiment of the present application, Figure 3 FIG. 2 is a structural schematic diagram of a component of the wearable device provided by the embodiment of the present application. As shown in Figure 2 , the wearable device 1 can include a device main body 10, a connecting band 20, and an adjusting device 30. In subsequent embodiments of the present application, only the wearable device 1 is specifically taken as a bracelet (or a watch) for example to be described, and the connecting band 20 is specifically taken as a watchband of the wearable device 1, the connecting band 20 is connected with the device main body 10, and the adjusting device 30 can be installed on the connecting band 20; for the case that the wearable device 1 is specifically taken as a VR device, earphones, glasses, or other types of wearable devices, please refer to the case that the wearable device 1 is specifically taken as a bracelet (or a watch) for understanding, and the embodiments of the present application will not be described one by one.

[0065] Please refer to Figure 3 , the adjusting device 30 can include two power sources, two transmission assemblies, and a roller shaft 301, the two power sources include a first power source 302 and a second power source 303, the two transmission assemblies include a first transmission assembly 304 and a second transmission assembly 305, the first power source 302 is connected with a first end of the roller shaft 301 through the first transmission assembly 304, the second power source 303 is connected with a second end of the roller shaft 301 through the second transmission assembly 305, the first end and the second end are two ends of the roller shaft 301 respectively, a rotating shaft of the first power source 302 is perpendicular to a rotating shaft of the roller shaft 301, and a rotating shaft of the second power source 303 is perpendicular to the rotating shaft of the roller shaft 301.

[0066] When the two power sources work synchronously, the first power source 302 drives the roller shaft 301 to rotate along a target direction through the transmission cooperation between the first transmission assembly 304 and the roller shaft 301, and the second power source 303 drives the roller shaft 301 to rotate along the target direction through the transmission cooperation between the second transmission assembly 305 and the roller shaft 301, when the roller shaft 301 rotates along the target direction, the connecting band 20 is driven to move, thereby realizing the driving of the connecting band 20 to perform a contraction operation or an expansion operation.

[0067] In the embodiment of the present application, through the above description; a scheme for automatically controlling the connecting band to perform a contraction operation or an expansion operation is provided, since the first power source and the second power source are located at two ends of the roller shaft, the roller shaft can be synchronously driven to rotate along a target direction, that is, balanced traction is provided at two ends of the roller shaft, which is beneficial to guarantee that the connecting band receives balanced traction, and is beneficial to reduce the wear of the connecting band and prolong the use time of the connecting band.

[0068] The first power source 302 can specifically adoptFigure 3 The motor shown is an example; for instance, the first power source 302 can be a stepper motor, a linear motor, or other types of motors. The first power source 302 can also be a power device other than a motor. The specific manifestations of the first power source 302 are not exhaustively listed here.

[0069] The second power source 303 has the same specific form as the first power source 302, and will not be described in detail here.

[0070] The first power source 302 can be fixed to the first side of the surface of the connecting belt 10, and the second power source 303 can be fixed to the second side of the surface of the connecting belt 10. The first side and the second side are different sides of the same surface of the connecting belt 10.

[0071] Optionally, the first power source 302 and the second power source 303 can be symmetrically distributed on both sides of the surface of the connecting belt 10. Specifically, in one implementation, such as... Figure 3 As shown, the first power source 302 and the second power source 303 can be axially symmetrical, and the axis of symmetry of the first power source 302 and the second power source 303 is the central axis of the roller 301.

[0072] In another implementation, the first power source 302 and the second power source 303 can be centrally symmetrical, with the center of symmetry of the first power source 302 and the second power source 303 being the center point of the roller 301. The "center point of the roller 301" can also be called the "center of gravity of the roller 301".

[0073] It should be noted that the first power source 302 and the second power source 303 may not be symmetrically distributed on both sides of the surface of the connecting belt 10, as long as it can be ensured that the driving force of the first power source 302 to the first side of the roller 301 and the driving force of the second power source 303 to the second side of the roller 302 are the same.

[0074] Since the components of the wearable device 1 may have errors during the production process, the relationship between the first power source 302 and the second power source 303 may not be a precise axisymmetric (or centrally symmetric) relationship. That is, in the actual product, due to error issues, there may be errors between the positional relationship between the first power source 302 and the second power source 303 and a precise axisymmetric (or centrally symmetric) relationship.

[0075] The rotation axis of the first power source 302 is parallel to the length direction of the connecting belt 20, and the rotation axis of the second power source 303 is also parallel to the length direction of the connecting belt 20, that is, the rotation axis of the first power source 302 is parallel to the rotation axis of the second power source 303. Since the rotation axis of the roller 301 is perpendicular to the rotation axis of the first power source 302 (or the second power source 303), the rotation axis of the roller 301 is parallel to the width direction of the connecting belt 20. The length direction of the connecting belt 20 can also be referred to as the long side direction of the connecting belt 20, and the width direction of the connecting belt 20 can also be referred to as the short side direction of the connecting belt. For a more intuitive understanding of the present scheme, please refer to Figure 4 , Figure 4 For the structure of the components of the wearable device provided in the embodiment of the present application, Figure 4 can be understood in combination with the above description of Figure 3 , Figure 4 is based on Figure 3 increased to the length direction of the connecting belt 20 and the width direction of the connecting belt 20, Figure 4 shows the length direction of the connecting belt 20 and the width direction of the connecting belt 20, it should be understood that Figure 4 in the example is only for the convenience of understanding the present scheme, and is not used to limit the present scheme.

[0076] Please refer to Figure 5 , Figure 5 For a structure of the adjusting device provided in the embodiment of the present application, please refer to Figure 5 , the adjusting device 30 can further include a driving assembly 306, the first power source 302 and the second power source 303 are fixedly connected with the driving assembly 306, and the driving assembly 306 is used to send a control signal to the first power source 302 and the second power source 303, and the control signal is used to indicate the output torque of the first power source 302 and the second power source 303. Wherein, the torque refers to the tendency of the force to make the object rotate around the rotation axis or fulcrum.

[0077] The above control signal can include a first control signal and a second control signal, and the driving assembly 306 sends the first control signal to the first power source 302 to control the output torque of the first power source 302; the driving assembly 306 sends the second control signal to the second power source 303 to control the output torque of the second power source 303.

[0078] For a further understanding of the present scheme, please refer to Figure 6 , Figure 6 For a structure of the adjusting device provided in the embodiment of the present application, Figure 6In the case of the first power source 302 and the second power source 303 being distributed in an axis symmetry, taking the central axis of the roller 301 as an example, the driving assembly 306 can include a processor 3061, a first circuit 3062 and a second circuit 3063. One end of the first circuit 3062 is connected to the processor 3061, and the other end of the first circuit 3062 is connected to the first power source 302. One end of the second circuit 3063 is connected to the processor 3061, and the other end of the second circuit 3063 is connected to the second power source 303. After the processor 3061 generates a control signal, the first circuit 3062 is configured to transmit the first control signal to the first power source 302, and the second circuit 3063 is configured to transmit the second control signal to the second power source 303. It should be understood that, Figure 6 The examples in the above description are only for the convenience of understanding the present application and do not limit the present application.

[0079] Further, in one working mode (i.e., the first working mode), the driving assembly 306 is configured to synchronously transmit control signals to the first power source 302 and the second power source 303 to control the first power source 302 and the second power source 303 to work synchronously. The synchronous working of the first power source 302 and the second power source 303 means that the first power source 302 and the second power source 303 start to output driving force at the same time, and the first power source 302 and the second power source 303 output driving force of the same size. Specifically, when the first power source 302 and the second power source 303 are both motors, it means that the first power source 302 and the second power source 303 start to rotate at the same time and have the same rotating speed.

[0080] Then, the driving assembly 306 can synchronously transmit the second control signal to the second power source 302 while transmitting the first control signal to the first power source 302 to instruct the first power source 302 and the second power source 303 to work synchronously. It should be noted that, due to the error in the circuit transmission process of the pulse signal, the time when the first power source 302 obtains the first control signal and the time when the second power source 303 obtains the second control signal can have an error, for example, an interval of 0.5 ms, 1 ms, 2 ms or other time lengths, which are not exhaustively listed herein. That is, the time when the first power source 302 obtains the first control signal and the time when the second power source 303 obtains the second control signal can not be exactly consistent.

[0081] Further, the first control signal and the second control signal can each specifically be a pulse signal. Specifically, in one implementation, when the driving assembly 306 synchronously sends a positive pulse signal (i.e., a specific form of the control signal) to the first power source 302 and the second power source 303 according to a first frequency, the first power source 302 and the second power source 303 can each output a torque according to a first speed, and the torque output by the first power source 302 and the torque output by the second power source 303 are transmitted to the roller 301 to drive the roller 301 to rotate in a first direction. When the roller 301 rotates in the first direction, the connecting belt 20 can be driven to move in a positive direction, i.e., to perform a contraction operation.

[0082] When the driving assembly 306 synchronously sends a negative pulse signal (i.e., another specific form of the control signal) to the first power source 302 and the second power source 303 according to a second frequency, since the electromagnetic signals generated by the positive pulse signal and the negative pulse signal are opposite, the first power source 302 and the second power source 303 can each output a torque in the opposite direction according to a second speed, and the torque output by the first power source 302 and the torque output by the second power source 303 are transmitted to the roller 301 to drive the roller 301 to rotate in a second direction. When the roller 301 rotates in the second direction, the connecting belt 20 can be driven to move in the opposite direction, i.e., to perform an extension operation.

[0083] The second direction and the first direction are opposite directions, i.e., if the first direction is a clockwise direction, the second direction is a counterclockwise direction; if the first direction is a counterclockwise direction, the second direction is a clockwise direction.

[0084] The first frequency and the second frequency can be the same or different, and correspondingly, the first speed and the second speed can be the same or different. As an example, the first frequency can have a value range of 50 Hz to 100 Hz, and as an example, the first frequency can have a value of 60 Hz, 70 Hz, 80 Hz, 90 Hz, or other values, etc. The specific value of the first frequency needs to be flexibly set in combination with the actual product and the actual application scenario, which is not limited here. The value of the second frequency can refer to the description of the value of the first frequency, which is not repeated here.

[0085] In another implementation, the driving assembly 306 can also synchronously send a negative pulse signal to the first power source 302 and the second power source 303 to drive the connecting belt 20 to perform an extension operation, and synchronously send a positive pulse signal to the first power source 302 and the second power source 303 to drive the connecting belt 20 to perform a contraction operation.

[0086] Further, if the first power source 302 and the second power source 303 are both motors, the rotational speed of the first power source 302 and the second power source 303 can be positively correlated with the frequency of the control signal sent by the driving assembly 306. That is, the greater the value of the first frequency (or the second frequency), the faster the rotational speed of the first power source 302 and the second power source 303, and the faster the rotational speed of the roller 301, and thus the faster the moving speed of the connecting belt 20; the smaller the value of the first frequency (or the second frequency), the slower the rotational speed of the first power source 302 and the second power source 303, and the slower the rotational speed of the roller 301, and thus the slower the moving speed of the connecting belt 20.

[0087] For example, when the first power source 302 and the second power source 303 are both stepper motors, when the driving assembly 306 sends a positive pulse signal to the first power source 302 (or the second power source 303), the first power source 302 (or the second power source 303) can rotate S steps in the positive direction, so that the rotational speed of the first power source 302 and the second power source 303 can be controlled by adjusting the sending frequency of the pulse signal (i.e., a specific form of the control signal). The value of S is an integer greater than or equal to 1. When the driving assembly 306 sends a negative pulse signal to the first power source 302 (or the second power source 303), the first power source 302 (or the second power source 303) can rotate S steps in the opposite direction.

[0088] Alternatively, the driving assembly 306 can output control signals to the first power source 302 and the second power source 303 at different frequencies at different times according to the scene requirements, so as to drive the roller 301 to rotate at different speeds at different times, and thus drive the connecting belt 20 to move at different speeds.

[0089] As an example, the wearable device 1 is embodied as a watch for example, and the watch can be configured with at least one type of sensor, which can include a pressure sensor configured on the connection band 20, the pressure sensor being used to measure the pressure value sensed by the connection band 20, i.e., the pressure value obtained by the pressure sensor is used to reflect the tightness of the connection band 20, in the case where the obtained pressure value is located in a first threshold interval, the driving assembly 306 can synchronously send control signals to the first power source 302 and the second power source 303 according to a first preset frequency; in the case where the obtained pressure value is located in a second threshold interval, the driving assembly 306 can synchronously send control signals to the first power source 302 and the second power source 303 according to a second preset frequency. Wherein the pressure value corresponding to the first threshold interval is less than the pressure value corresponding to the second threshold interval, the first preset frequency is greater than the second preset frequency, and the rotational speed of the first power source 302 and the second power source 303 is positively correlated with the sending frequency of the control signal; that is, the faster the movement speed of the watch band (an example of the connection band) worn by the user, the looser the watch band, it should be understood that this is only an example when the wearable device 1 is embodied as a watch, when the wearable device 1 is embodied in other forms, control signals can also be synchronously sent to the first power source 302 and the second power source 303 at different frequencies in other scenarios, which is not enumerated here.

[0090] In the embodiments of the present application, when the first power source 302 and the second power source 303 are both motors, the rotational speed of the first power source 302 and the second power source 303 is positively correlated with the sending frequency of the control signal, so that the driving assembly 306 can adjust the rotational speed of the first power source 302 and the second power source 303 by adjusting the sending frequency of the control signal, thereby adjusting the speed of the connection band 20 performing the contraction operation or the expansion operation according to the actual application scenario, which is beneficial to improve the flexibility of the present solution.

[0091] Optionally, the adjusting device 30 can further include a first sensor 307 and a second sensor 308. The first sensor 307 is fixed to the first side of the connection band 20, i.e., the first sensor 307 and the first power source 302 are fixed to the same side of the connection band 20; the second sensor 308 is fixed to the second side of the connection band 20, i.e., the second sensor 308 and the second power source 303 are fixed to the same side of the connection band 20. It should be noted that the first sensor 307 and the second sensor 308 can be the same sensor as the above-mentioned pressure sensor, or can be different sensors.

[0092] The first sensor 307 is used to acquire a first pressure value, that is, when the wearable device 1 is worn by the user, the first sensor 307 is used to acquire the first pressure value generated by the user on the first side of the connecting strap 20; the second sensor 308 is used to acquire a second pressure value, that is, when the wearable device 1 is worn by the user, the second sensor 308 is used to acquire the second pressure value generated by the user on the first side of the connecting strap 20.

[0093] Specifically, the first sensor 307 and the second sensor 308 can be a resistance sensor, a voltage sensor, a photosensitive sensor, or other types of sensors, as long as they are sensors capable of acquiring pressure values. The types of the first sensor 307 and the second sensor 308 will not be exhaustively listed here.

[0094] Since the first power source 302 and the second power source 303 can be deployed on the outer surface of the connecting strap 20, and the first sensor 307 and the second sensor 308 are used to acquire the pressure exerted by the user on the connecting strap 20, the first sensor 307 and the second sensor 308 can be deployed on the inner surface of the connecting strap 20. That is, the first sensor 307 and the first power source 302 can be deployed on two different surfaces of the connecting strap 20, and the second sensor 308 and the second power source 303 can be deployed on two different surfaces of the connecting strap 20. The outer surface and the inner surface of the connecting strap 20 are two parallel and different surfaces of the connecting strap 20. When the user wears the wearable device 1, the surface of the connecting strap 20 that is closest to the user's skin is called the inner surface of the connecting strap.

[0095] To more intuitively understand the positions of the first sensor 307 and the second sensor 308, please refer to [link / reference]. Figure 7 , Figure 7 This is a schematic diagram of the structure of a wearable device component provided in an embodiment of this application, such as... Figure 7 As shown, the first sensor 307 is deployed on the first side of the connecting strip 20, and the second sensor 308 is deployed on the second side of the connecting strip 20. Figure 7 The first sensor 307, the second sensor 308, the first power source 302, and the second power source are displayed on the same surface of the connecting belt 20. It should be understood that in the actual product, the first sensor 307 and the first power source 302 can be deployed on two different surfaces of the connecting belt 20, and the second sensor 308 and the second power source 308 can be deployed on two different surfaces of the connecting belt 20. Figure 7 The examples in the text are for the purpose of making it easier to understand the concepts of the first side and the second side of the connecting strip 20. The positions of the first sensor 307 and the second sensor 308 in the actual product are not limited here.

[0096] Specifically, if the driving assembly 306 (i.e., the processor 3601 in the driving assembly 306) determines that the pressure difference between the first side and the second side of the connection belt 20 is greater than or equal to the pressure threshold value according to the first pressure value and the second pressure value, the driving assembly 306 can enter another working mode (i.e., the second working mode). Instead of sending control signals to the first power source 302 and the second power source 303 synchronously, the driving assembly 306 sends control signals to the first power source 302 and the second power source 303 in different numbers within a target time period, so as to reduce the pressure difference between the first side and the second side, wherein the rotation speed of the first power source 302 and the second power source 303 is positively correlated with the sending frequency of the control signals.

[0097] For the determination process of "the pressure difference between the first side and the second side is greater than or equal to the pressure threshold value". In an implementation, the driving assembly 306 (i.e., the processor 3601 in the driving assembly 306) can directly determine the first difference between the first pressure value and the second pressure value as the pressure difference between the first side and the second side of the connection belt 20.

[0098] In another implementation, the driving assembly 306 (i.e., the processor 3601 in the driving assembly 306) can obtain a plurality of first pressure values and calculate the average value of the plurality of first pressure values; and the driving assembly 306 obtains a plurality of second pressure values and calculates the average value of the plurality of second pressure values; the driving assembly 306 calculates the second difference between the average value of the plurality of first pressure values and the average value of the plurality of second pressure values, and determines the aforementioned second difference as the pressure difference between the first side and the second side of the connection belt 20.

[0099] For the specific implementation process of "reducing the pressure difference between the first side and the second side". In the case that the connection belt 20 performs the contraction operation, if the pressure difference between the first side and the second side of the connection belt 20 is greater than or equal to the pressure threshold value, the driving assembly 306 sends more control signals to the side with smaller pressure value between the first side and the second side of the connection belt 20 within a target time period, so as to reduce the pressure difference between the first side and the second side of the connection belt 20. The value of the target time period can be 1 second, 2 seconds or other time length, and the value of the specific target time period can be flexibly set in combination with the actual application scenario, which is not limited here.

[0100] More specifically, in one implementation, if the driving component 306 determines that the pressure difference between the first side and the second side of the connection band 20 is greater than or equal to the pressure threshold, the driving component 306 can suspend sending control signals to the power source of the side of the first side and the second side of the connection band 20 with the greater pressure value and send M control signals to the power source of the side of the first side and the second side of the connection band 20 with the smaller pressure value in the target time period, i.e., only the power source of the side of the first side and the second side of the connection band 20 with the smaller pressure value outputs driving force in the target time period to reduce the pressure difference between the first side and the second side of the connection band 20. M is an integer greater than or equal to 1, and as an example, M can be 1, 2, or other values, which are not exhaustively listed here.

[0101] In another implementation, if the driving component 306 determines that the pressure difference between the first side and the second side of the connection band 20 is greater than or equal to the pressure threshold, the driving component 306 sends control signals to the power sources of the first side and the second side of the connection band 20 at different frequencies in the target time period, and the driving component 306 sends control signals to the power source of the side of the first side and the second side of the connection band 20 with the smaller pressure value at a faster frequency, so that the driving component 306 sends more control signals to the power source of the side of the first side and the second side of the connection band 20 with the smaller pressure value in the target time period to reduce the pressure difference between the first side and the second side of the connection band 20.

[0102] In the case where the connection band 20 performs the stretching operation, if the pressure difference between the first side and the second side of the connection band 20 is greater than or equal to the pressure threshold, the driving component 306 sends more control signals to the side of the first side and the second side of the connection band 20 with the greater pressure value in the target time period to reduce the pressure difference between the first side and the second side of the connection band 20.

[0103] More specifically, in one implementation, if the driving component 306 determines that the pressure difference between the first side and the second side of the connection band 20 is greater than or equal to the pressure threshold, the driving component 306 can suspend sending control signals to the power source of the side of the first side and the second side of the connection band 20 with the smaller pressure value and send M control signals to the power source of the side of the first side and the second side of the connection band 20 with the greater pressure value in the target time period, i.e., only the power source of the side of the first side and the second side of the connection band 20 with the greater pressure value outputs driving force in the target time period to reduce the pressure difference between the first side and the second side of the connection band 20.

[0104] In another implementation, if the driving assembly 306 determines that the pressure difference between the first side and the second side of the connection belt 20 is greater than or equal to the pressure threshold, the driving assembly 306 sends control signals to the power sources of the first side and the second side of the connection belt 20 at different frequencies respectively within the target time period, and the driving assembly 306 sends control signals to the power source of the side with a greater pressure value between the first side and the second side of the connection belt 20 at a faster frequency, so that the driving assembly 306 sends more control signals to the power source of the side with a greater pressure value between the first side and the second side of the connection belt 20 within the target time period, so as to reduce the pressure difference between the first side and the second side of the connection belt 20.

[0105] In the embodiments of the present application, the pressure difference between the first side and the second side of the connection belt 20 is also obtained by the first sensor 307 and the second sensor 308, and in the case where the pressure difference between the first side and the second side of the connection belt 20 is greater than or equal to the pressure threshold, the number of control signals sent to the first power source and the second power source within the target time period is different, so as to reduce the pressure difference between the first side and the second side of the connection belt 20; that is, a feedback mechanism is provided, which can timely adjust the pressure difference between the first side and the second side of the connection belt 20, so as to further ensure that the connection belt 20 can be subjected to balanced traction, which is beneficial to reducing the wear of the connection belt and prolonging the service life of the connection belt.

[0106] In the embodiments of the present application, when the two power sources work synchronously, the first power source 302 drives the roller shaft 301 to rotate in a target direction through the first transmission assembly 304 and the first end of the roller shaft 301, and the second power source 303 drives the roller shaft 301 to rotate in the target direction through the second transmission assembly 305 and the second end of the roller shaft 301. The target direction can be a clockwise direction or a counterclockwise direction.

[0107] In an implementation, the first transmission assembly 304 and the second transmission assembly 305 can both adopt a gear transmission mode. The first transmission assembly 304 can specifically be a first gear set, and the second transmission assembly 305 can specifically be a second gear set, and the first gear set and the second gear set each include at least one gear.

[0108] For a more intuitive understanding of the present scheme, please refer to Figure 8 , Figure 8 A structural schematic diagram of the connection relationship between the power source, the transmission assembly and the roller shaft provided in the embodiments of the present application, Figure 8The position relationship of the power source, the transmission assembly and the roller 301 is shown in the figure. One transmission assembly can include a face gear. Optionally, one transmission assembly can also include a motor gear. Further, one gear can include two parallel first planes and one second plane. The gear of the face gear is arranged on the first plane, and the gear of the motor gear is arranged on the second plane.

[0109] As shown in the figure, the last gear of each transmission assembly can be fixedly connected with the roller 301. The last gear of each transmission assembly can be detachably connected with the roller 301, or can be integrally formed with the roller 301. Figure 8 It should be noted that,

[0110] The figure in the figure is only an example for easy understanding of the scheme. In other examples, the face gear can be directly fixedly connected with the roller 301, that is, there can be no multi-stage gear transmission between the face gear and the roller 301, or the transmission assembly can also be in the form of other types of gear transmission. The example is only for easy understanding of the realizability of the scheme, and is not used to limit the scheme. Figure 8 The first gear set 304 (that is, an example of the first transmission assembly 304) and the second gear set 305 (that is, an example of the second transmission assembly 305) can each include a target gear. The target gear in the first gear set 304 can be used to convert the direction of the driving force output by the first power source 302, and the target gear in the second gear set 305 can be used to convert the direction of the driving force output by the second power source 303.

[0111] Further, the first power source 302 and the second power source 303 can output torque on a plane parallel to the connecting belt 20. The target gear in the first gear set 304 (that is, an example of the first transmission assembly 304) is used to convert the torque output by the first power source 302 into torque on a plane perpendicular to the connecting belt 20. The target gear in the second gear set 305 (that is, an example of the second transmission assembly 305) is used to convert the torque output by the second power source 303 into torque on a plane perpendicular to the connecting belt 20.

[0112]

[0113] ​The target gear can be any one of a face gear, a worm gear, a bevel gear or a bevel gear. Further, if the target gear is a bevel gear, the target gear can be any one of a helical bevel gear, a straight bevel gear or other types of bevel gears. If the target gear is a bevel gear, the target gear can be any one of an equi-section bevel gear, an arcuate bevel gear, a bevel gear, a straight bevel gear, a helical bevel gear, an arcuate bevel gear or other types of bevel gears. The shape of the target gear is not limited.

[0114] For a better understanding of the present application, please refer to Figure 9 , Figure 9 A structure diagram of the connection between the power sources and the transmission assemblies provided by the embodiments of the present application is shown in Figure 9 , Figure 9 For example, the target gear is a face gear in the example, the output end of each power source is a third gear, the third gear rotates in a plane parallel to the connection belt 20, and each transmission assembly includes a face gear meshing with the third gear (i.e. the face gear in the target gear), which is used to change the direction of the driving force output by the power source. The third gear rotates in a plane parallel to the connection belt 20, and the face gear (i.e. the target gear) rotates in a plane perpendicular to the connection belt 20. It should be understood that Figure 9 The example is only for the convenience of understanding the present application and is not used to limit the present application.

[0115] In the embodiments of the present application, the first gear set 304 (i.e. an example of the first transmission assembly 304) and the second gear set 305 (i.e. an example of the second transmission assembly 305) are both configured with a target gear for changing the direction of the driving force output by the power source, and multiple implementation modes of the target gear are provided, which is beneficial to improve the implementation flexibility of the present application and expand the application scenarios of the present application.

[0116] Optionally, the first gear set 304 (i.e. an example of the first transmission assembly 304) can also be used to increase the torque of the driving force output by the first power source 302, and the second gear set 305 (i.e. an example of the second transmission assembly 305) can also be used to increase the torque of the driving force output by the second power source 303; that is, the driving force obtained by the roller 301 can be greater than the sum of the driving forces output by the first power source 302 and the second power source 303, so as to be able to provide a greater driving force to the connection belt 20.

[0117] In the embodiment of the present application, when the user is in a running state or the like, the power source may need to provide greater traction. After the first transmission assembly 304 and the second transmission assembly 305 amplify the torque of the driving force output by the power source, the roller 301 will obtain greater driving force, so that the roller 301 can provide greater traction to the connecting belt 20, and thus the power source can provide sufficient power to support the connecting belt to perform the contraction operation or the expansion operation in more scenarios, which is beneficial to expand the application scenarios of the present scheme.

[0118] In addition, when neither the first power source 302 nor the second power source 303 is working, the connecting belt 20 may be subjected to external traction. The traction received by the connecting belt 20 can be conducted to the first power source 302 through the roller 301 and the first transmission assembly 304, and the traction received by the connecting belt 20 can also be conducted to the second power source 303 through the roller 301 and the second transmission assembly 305. The first transmission assembly 304 is further configured to reduce the traction conducted to the first power source 302, and the second transmission assembly 305 is further configured to reduce the traction conducted to the second power source 303. Since the smaller traction is lower than the resistance of the first power source 302 (or the second power source 303) itself, the self-locking of the first power source 302 and the second power source 303 can be achieved. That is, during the process in which the user wears the wearable device 1, the connecting belt 20 will not easily perform the contraction or expansion operation, so that the user can comfortably wear the wearable device 1.

[0119] The first gear set 304 (i.e., an example of the first transmission assembly 304) is in transmission connection with the first end of the roller 301, and the second gear set 305 (i.e., an example of the second transmission assembly 305) is in transmission connection with the second end of the roller 301. When the two power sources are working, the ratio between the torque obtained by the first end of the roller 301 and the torque output by the first power source 302 is within a target interval, the ratio between the torque obtained by the second end of the roller 301 and the torque output by the second power source 303 is within the target interval, and the transmission ratio of the first gear set 304 and the transmission ratio of the second gear set 305 are both within the target interval. The value of the target interval can be 50 to 100.

[0120] For a more intuitive understanding of the present scheme, please refer to Figure 10 , Figure 10 A principle diagram of the relationship between the torque ratio and the transmission ratio provided by the embodiment of the present application is as follows Figure 10As shown, the radius of gear B is 40, the radius of gear A is 16, the gear shapes on gear B and gear A are consistent, and the transmission ratio between gear B and gear A is 2.5 (i.e., 40 / 16). After a positive west rotation driving force is applied to gear A, the ratio between the torque output by gear B and the torque output by gear A is 2.5, i.e., although the rotation speed of gear B is reduced, the torque output by gear B is increased. It should be understood that, Figure 10 The examples in the foregoing merely serve to facilitate the understanding of the present solution and do not serve to limit the present solution.

[0121] In the embodiments of the present application, the transmission ratio of the first gear set and the transmission ratio of the second gear set are disclosed, which is conducive to reducing the implementation difficulty of the present solution.

[0122] Specifically, in an implementation manner, the first gear set 304 (i.e., an example of the first transmission assembly 304) and the second gear set 305 (i.e., an example of the second transmission assembly 305) each include a plurality of first gears, and each first gear includes N gears coaxially, where N is an integer greater than or equal to 2. When N is 2, the first gear can also be referred to as a double gear, and when N is 3, the first gear can also be referred to as a triple gear, etc. The specific selection of the first gear can be flexibly set in combination with the actual product form, which is not limited here.

[0123] Further, the N gears included in the first gear include a first sub-gear and a second sub-gear, the radius of the second sub-gear is smaller than the radius of the first sub-gear, and the tooth profile shape of the second sub-gear can be consistent with the tooth profile shape of the first sub-gear; the first sub-gear in the first gear is used to mesh with the previous gear (i.e., the gear closer to the power source), and the second sub-gear in the first gear is used to mesh with the next gear (i.e., the gear closer to the roller 301). Thus, when the two power sources work synchronously, the plurality of first gears included in the first transmission assembly 304 are used to increase the torque of the driving force output by the first power source 302; and the plurality of first gears included in the second transmission assembly 305 are used to increase the torque of the driving force output by the second power source 303.

[0124] It should be noted that the target gear included in each gear set can be a first gear, i.e., the target gear can include a plurality of gears coaxially, the first sub-gear in the target gear (i.e., the first gear) is connected with the power source, and the second sub-gear in the target gear (i.e., the first gear) is meshed with the next gear; the target gear included in each gear set can also not be a first gear, and the specific implementation can be determined in combination with the actual product form, which is not limited here.

[0125] In the embodiments of the present application, a plurality of first gears can be arranged in each transmission assembly, so that a gear with a larger radius in the first gears can mesh with the previous gear, and a gear with a smaller radius in the first gears can mesh with the next gear. Since the rotational speed will decrease and the driving force will increase when the driving force is transmitted from the gear with a smaller radius to the gear with a larger radius, the radius of the gear can be reduced without changing the rotational speed by the first gears, and the multi-stage transmission by the plurality of first gears in each transmission assembly is beneficial to increasing the driving force output by the power source while reducing the radius of the gear connected to the roller 301, that is, beneficial to reducing the radius of the largest gear in the transmission assembly, thereby reducing the thickness of the entire driving device 30.

[0126] Further, in one case, referring to Figure 11 , Figure 11 The description of the above-mentioned Figure 8 should be understood, Figure 11 A schematic diagram of the transmission assembly provided by the embodiments of the present application is shown in the figure. Each of the first transmission assembly 304 and the second transmission assembly 305 includes a plurality of first gears, each of which directly meshes with the next first gear, that is, the second sub-gear with a smaller radius in a first gear directly meshes with the first sub-gear with a larger radius in the next first gear. It should be understood that Figure 11 The examples in the above-mentioned

[0127] In another case, the first transmission assembly 304 and the second transmission assembly 305 each include a plurality of first gears, and the two first gears can be cooperatively transmitted by at least one third gear, and there is only one gear on the shaft of the third gear.

[0128] In another implementation, the first transmission assembly 304 and the second transmission assembly 305 can also only include a plurality of third gears, that is, neither the first transmission assembly 304 nor the second transmission assembly 305 includes a first gear, and the radius of the last gear in the first transmission assembly 304 and the second transmission assembly 305 (that is, the gear directly connected to the roller 301) is larger.

[0129] It should be noted that the sizes of the plurality of gears included in the first transmission assembly 304 and the sizes of the plurality of gears included in the second transmission assembly 305 can be the same or different, as long as the ratio between the driving force obtained by the first end of the roller 301 and the driving force output by the first power source 302 and the ratio between the driving force obtained by the second end of the roller 301 and the driving force output by the second power source 303 are the same. The design of the plurality of gears in the first transmission assembly 304 and the second transmission assembly 305 can be flexibly set according to the actual product form, which is not limited here.

[0130] The shape of the tooth profile corresponding to the gears included in the first transmission component 304 and the second transmission component 305 can be an axisymmetric figure. For example, it can be an isosceles triangle, an isosceles trapezoid, a square, or other axisymmetric figures, etc. This is not an exhaustive list. The specific shape of the tooth profile corresponding to the gears included in the first transmission component 304 and the second transmission component 305 can be flexibly set according to the actual product form, and is not limited here.

[0131] In this embodiment, since the tooth profile of the gears included in the transmission assembly is an axisymmetric shape, the gears can mesh with each other regardless of whether they rotate in the forward or reverse direction, thereby achieving good transmission of driving force, which helps to reduce wear between gears and extend the service life of the transmission assembly. In addition, when the tooth profile of the gears included in the first transmission assembly 304 and the second transmission assembly 305 is an isosceles trapezoid, the noise generated by the two transmission assemblies during operation can also be reduced.

[0132] In another implementation, both the first transmission assembly 304 and the second transmission assembly 305 can be belt drives. For a more intuitive understanding of this solution, please refer to [link to relevant documentation]. Figure 12 , Figure 12 This is a schematic diagram of a transmission component in a wearable device provided in an embodiment of this application. Figure 12 As shown, the first transmission assembly 304 may include a driving pulley, a transmission belt, and a driven pulley. The driving pulley in the first transmission assembly 304 is connected to the first power source 302. The driving pulley and the driven pulley in the first transmission assembly 304 are connected by a transmission belt. The driven pulley in the first transmission assembly 304 can be connected to the first end of the roller 301, so that the first power source 302 can transmit the output driving force to the first end of the roller 301 through the first transmission assembly 304. It should be noted that when the radius of the driven pulley in the first transmission assembly 304 is larger than that of the driving pulley in the first transmission assembly 304, the first transmission assembly 304 can amplify the torque generated by the first power source 302, but... Figure 12 The examples in this paper are only for the convenience of understanding this solution. In actual products, the radius of the driving wheel in the first transmission assembly 304 and the radius of the driven wheel in the first transmission assembly 304 can also be the same. In addition, the structure of the second transmission assembly 305 is the same as that of the first transmission assembly 304, and the structure of the second transmission assembly 305 will not be described in detail here.

[0133] Further, since the rotation shaft of the first power source 302 is perpendicular to the rotation shaft of the roller 301, and the rotation shaft of the second power source 303 is perpendicular to the rotation shaft of the roller 301, the driving wheel of the first transmission assembly 304 can be used to convert the direction of the driving force output by the first power source 302, and the driving wheel of the second transmission assembly 305 can be used to convert the direction of the driving force output by the second power source 303.

[0134] Further, the first power source 302 and the second power source 303 can output torque in a plane parallel to the connecting belt 20, the driving wheel of the first transmission assembly 304 can be used to convert the torque output by the first power source 302 into torque in a plane perpendicular to the connecting belt 20, and the driving wheel of the second transmission assembly 305 can be used to convert the torque output by the second power source 303 into torque in a plane perpendicular to the connecting belt 20.

[0135] In the embodiment of the present application, when the roller 301 rotates in the target direction, the connecting belt 20 is driven to move to perform the contraction operation or the expansion operation. That is, the roller 301 can be provided with a first driving part, and the connecting belt 20 can be provided with a second driving part, and when the roller 301 rotates in the target direction, the first driving part on the roller 301 and the second driving part on the connecting belt 20 cooperate to drive the connecting belt 20 to move.

[0136] As an example, for a more intuitive understanding of the present scheme, please refer to Figure 13 , Figure 13 A schematic diagram of the first driving part and the second driving part provided in the embodiment of the present application is shown in the figure, the outer surface of the roller 301 can be provided with a gear (that is, the first driving part is in the form of a gear), and the connecting belt 20 can be provided with a rack (that is, the second driving part is in the form of a rack), so that when the roller 301 rotates in the target direction, the gear on the outer surface of the roller 301 meshes with the rack on the connecting belt 20 to drive the connecting belt 20 to move.

[0137] As another example, for example, the first driving part on the roller 301 can include a plurality of protruding blocks, and the second driving part on the connecting belt 20 can include a plurality of recesses corresponding to the plurality of protruding blocks, and when the roller 301 rotates in the target direction, the plurality of protruding blocks on the roller 301 can be embedded in the plurality of recesses on the second driving part to drive the connecting belt 20 to move.

[0138] As another example, for example, the first driving part on the roller 301 can include a plurality of recesses, and the second driving part on the connecting belt 20 can include a plurality of protruding blocks corresponding to the plurality of recesses, and when the roller 301 rotates in the target direction, the plurality of recesses on the roller 301 can be embedded in the plurality of protruding blocks on the second driving part to drive the connecting belt 20 to move.

[0139] As another example, the first driving part on the roller 301 can include a plurality of protruding strips, and the second driving part on the connecting band 20 can include a plurality of strip-shaped recesses corresponding to the plurality of protruding strips. When the roller 301 rotates in the target direction, the plurality of protruding strips on the roller 301 can be embedded in the plurality of strip-shaped recesses on the second driving part to drive the connecting band 20 to move, and the like.

[0140] It should be noted that the second driving part on the connecting band 20 can also be designed in other pattern shapes, and correspondingly, the first driving part on the roller 301 needs to be designed in a shape corresponding to the second driving part, as long as it can drive the connecting band 20 to move when the roller 301 rotates in the target direction. The shape of the first driving part on the roller 301 and the shape of the second driving part on the connecting band 20 can be flexibly set in combination with the actual product form, which is not limited here.

The rotation shaft of the first power source 302 is perpendicular to the rotation shaft of the roller 301. The rotation shaft of the second power source 303 is perpendicular to the rotation shaft of the roller 301.

[0154] It should be noted that the specific structure of the adjusting device 30 provided in the embodiments of the present application can be referred to the description of the corresponding embodiments, which will not be repeated here. Figures 2 to 13 The description of the corresponding embodiments, which will not be repeated here.

[0155] In Figures 2 to 13 On the basis of the corresponding embodiments, in order to better implement the above-mentioned scheme of the embodiments of the present application, the following also provides a related method for implementing the above-mentioned scheme. The control method of the connecting band of the wearable device provided in the embodiments of the present application can be applied to Figures 2 to 13 the corresponding wearable device, the wearable device includes a processor, a sensor, a connecting band, and an adjusting device, the adjusting device is disposed on the connecting band of the wearable device, the adjusting device includes two power sources, two transmission assemblies, and a roller shaft, the two power sources include a first power source and a second power source, the two transmission assemblies include a first transmission assembly and a second transmission assembly, the first power source is connected to the first end of the roller shaft through the first transmission assembly, the second power source is connected to the second end of the roller shaft through the second transmission assembly, the first end and the second end are two ends of the roller shaft, the shaft of the first power source is perpendicular to the shaft of the roller shaft, and the shaft of the second power source is perpendicular to the shaft of the roller shaft. For details, please refer to Figure 14 , Figure 14 A method flowchart of the control method of the connecting band of the wearable device provided in the embodiments of the present application, the control method of the connecting band of the wearable device provided in the embodiments of the present application can include:

[0156] 1401. The processor collects measurement values through the sensor.

[0157] In the embodiments of the present application, the wearable device can be configured with any one or more of the following sensors: a pressure sensor, a temperature sensor, a humidity sensor, an inertial sensor, an acceleration sensor, or other types of sensors, etc. The specific configuration of which type of sensor needs to be determined in combination with the first condition, that is, what type of condition is used, which is not limited here. The processor can collect measurement values in real time through at least one configured sensor.

[0158] 1402、When the processor determines that the first condition is met according to the measurement value collected by the sensor, control signals are synchronously sent to the first power source and the second power source, and the control signals are used to control the first power source and the second power source to output driving force; the first transmission assembly is in transmission cooperation with the roller shaft, and the driving force output by the first power source is transmitted to the roller shaft to drive the roller shaft to rotate in the target direction; the second transmission assembly is in transmission cooperation with the roller shaft, and the driving force output by the second power source is transmitted to the roller shaft to drive the roller shaft to rotate in the target direction; and the connecting band is driven to move when the roller shaft rotates in the target direction.

[0159] In the embodiments of the application, when the processor determines that the first condition is met according to the measurement value collected by the sensor, the processor of the wearable device is in the first working mode, that is, the control signals are synchronously sent to the first power source and the second power source, and the control signals are used to control the first power source and the second power source to output driving force.

[0160] In one implementation, the sensor used in step 1401 includes a pressure sensor arranged on the connecting band, and the pressure sensor is used to measure the pressure value sensed by the connecting band, that is, the pressure value obtained by the pressure sensor is used to reflect the tightness of the connecting band. For example, when the wearable device is a bracelet, the pressure value obtained by the pressure sensor is the pressure caused by the user's arm to the connecting band; as another example, when the wearable device is a headset, the pressure value obtained by the pressure sensor is the pressure caused by the user's head to the connecting band. In another implementation, the sensor used in step 1401 includes a pressure sensor arranged on the main body of the wearable device. For example, when the wearable device is glasses, the pressure sensor can be arranged at the tail of the glasses leg, and the pressure value obtained by the pressure sensor can be the pressure caused by the user's ear to the tail of the glasses leg.

[0161] In the above several implementations, when the pressure value obtained by the pressure sensor is within the preset threshold interval, it is considered that the first condition is met. It should be noted that when the wearable device is in different types of product forms, the value of the preset threshold interval can be different, and the value of the specific preset threshold interval can be determined in combination with the actual application scene, which is not limited here.

[0162] Further, in one case, when the roller drivingly connects the band to move to implement the contraction operation, the preset threshold interval can also be divided into a first threshold interval and a second threshold interval. In a case where the processor determines that the pressure value acquired by the sensor is located in the first threshold interval, the control signal is synchronously sent to the first power source and the second power source according to a first frequency; in a case where the processor determines that the pressure value acquired by the sensor is located in the second threshold interval, the control signal is synchronously sent to the first power source and the second power source according to a second frequency; wherein the pressure value corresponding to the first threshold interval is less than the pressure value corresponding to the second threshold interval, the first frequency is greater than the second frequency, and the rotational speed of the first power source and the second power source is positively correlated with the sending frequency of the control signal. The specific implementation of the foregoing steps can be referred to Figures 2 to 13 the description of the corresponding embodiments.

[0163] In another case, in a case where the processor determines that the pressure value acquired by the sensor is located in the entire preset threshold interval, the control signal is synchronously sent to the first power source and the second power source according to the same frequency.

[0164] In another implementation, the sensor used in step 1401 can include a temperature sensor configured on the connecting band, and when the temperature value acquired by the temperature sensor is greater than or equal to a target temperature value, the driving of the connecting band to move to perform the stretching operation can be triggered; since in the process of wearing the wearable device by the user, if it is found through the temperature sensor that the temperature of the user's body surface is too high, the connecting band can be appropriately loosened to reduce the temperature of the user's body surface, thereby providing the user with a more comfortable wearing experience, which is conducive to improving the user stickiness of the present scheme.

[0165] In another implementation, the sensor used in step 1401 can include a humidity sensor configured on the connecting band, and when the humidity value acquired by the humidity sensor is greater than or equal to a target humidity value, the driving of the connecting band to move to perform the stretching operation can be triggered; since in the process of wearing the wearable device by the user, if it is found through the humidity sensor that the humidity of the user's body surface is too high, it proves that the user may sweat during wearing, and the connecting band can be appropriately loosened to reduce the humidity of the user's body surface, thereby providing the user with a more comfortable wearing experience.

[0166] In another implementation, the sensor used in step 1401 can include an inertial sensor or an acceleration sensor, which is used to acquire the current motion condition of the wearable device. When it is determined according to the measurement value collected by the inertial sensor that the moving speed of the wearable device is greater than or equal to a target speed value, or when it is determined according to the measurement value collected by the acceleration sensor that the acceleration of the wearable device is greater than or equal to a target acceleration, the first condition is considered to be met, and the driving connection belt can be triggered to move to perform the contraction operation; since the user is in a state of rapid motion, the wearable device is easily subjected to centrifugal force, and the driving connection belt is triggered to move to perform the contraction operation, which can avoid the wearable device from falling off.

[0167] It should be noted that when the first condition specifically represents other types of conditions, other types of sensors can be used in step 1401, and the examples provided herein are only used to prove the feasibility of the present solution and do not limit the present solution.

[0168] In the embodiments of the present application, the specific implementation of step 1402 and the specific structure of the wearable device can be referred to the description in the corresponding embodiments, which will not be repeated here. Figures 2 to 13

[0169] 1403, when the processor determines that the second condition is met according to the pressure values obtained by the first sensor and the second sensor, the number of control signals sent by the processor to the first power source and the second power source within a target time period is different, so as to reduce the pressure difference between the first side and the second side; the second condition and the first condition are different conditions, and the second condition includes determining that the pressure difference between the first side and the second side of the connection belt is greater than or equal to a pressure threshold according to the first pressure value and the second pressure value, and the rotation speed of the first power source and the second power source is positively correlated with the sending frequency of the control signal.

[0170] In some embodiments of the present application, the wearable device can be configured with a first sensor and a second sensor. The positions of the first sensor and the second sensor in the wearable device can be referred to the description in the corresponding embodiments, which will not be repeated here. Figures 2 to 13

[0171] When the processor determines that the second condition is met according to the pressure values obtained by the first sensor and the second sensor, the processor of the wearable device can enter a second working mode, that is, the number of control signals sent by the processor to the first power source and the second power source within a target time period is different, so as to reduce the pressure difference between the first side and the second side; the specific implementation of step 1403 can be referred to the description in the corresponding embodiments, which will not be repeated here. Figures 2 to 13 ​​The descriptions in the corresponding embodiments are not repeated here. After the target time period, the processor of the wearable device can re-enter the first working mode, that is, synchronously send control signals to the first power source and the second power source. The control signals are used to control the output driving force of the first power source and the second power source.
