Description

Technical Field

[0001] The present application relates to the field of wearable devices, and in particular to a wearable device and a control method thereof. Background Art

[0002] In the field of blood pressure measurement, wearable blood pressure measurement devices are gradually appearing in the market and clinical use. Wearable blood pressure measurement devices can be used to measure blood pressure anytime and anywhere, and need to be worn for a long time in daily life.

[0003] However, traditional wearable blood pressure measurement devices have high requirements for tightness to ensure accurate measurement, which may be inconsistent with the tightness that users are accustomed to. If the tightness required for accurate measurement is maintained for a long time, it will affect the user's wearing comfort. Summary of the invention

[0004] The purpose of the present application is to provide a wearable device and a control method thereof. The wearable device includes a main body, a connecting belt and an elastic rope. When worn daily, the connecting belt and the main body are elastically connected by the elastic rope, and the wearing tightness of the wearable device is adaptively adjusted by the elastic rope, which is comfortable to wear; when detecting, there is no elastic connection between the connecting belt and the main body, and the wearable device can maintain the wearing tightness required for detection.

[0005] In a first aspect, the present application provides a wearable device for detecting a target parameter, wherein the wearable device includes a main body, a connecting belt and an elastic rope. The main body includes a shell and a locking mechanism installed on the shell. The first end of the connecting belt is connected to the shell, and the second end of the connecting belt is elastically connected to the shell through the elastic rope. When the wearable device is in a detection state, the locking mechanism controls the elastic connection of the elastic rope to fail. When the wearable device is in a non-detection state, the locking mechanism releases the control of the elastic rope, so that the elastic rope resumes the elastic connection.

[0006] In the present application, the failure of the elastic connection of the elastic cord is controlled by mechanical control of the connecting belt by a locking mechanism, so that the second end of the connecting belt is fixed relative to the shell when the wearable device is in the detection state, which is conducive to the entire connecting belt being stably fitted to the wearing part of the human body, so that the main body can be worn stably to ensure detection accuracy. The control of restoring the elastic connection of the elastic cord is achieved by mechanical control of the connecting belt by a locking mechanism, so that when the wearable device is in the non-detection state, the second end of the connecting belt can move relative to the shell to achieve adjustable wearing circumference of the wearable device, thereby improving wearing comfort. Therefore, the present application achieves stable wearing of the wearable device in the detection state to ensure accurate detection, and adjustable wearing in the non-detection state to ensure comfortable wearing through the locking mechanism.

[0007] In some possible implementations, the locking mechanism includes a connector and a latch, wherein the first end of the connector is connected to the elastic rope, the second end of the connector is connected to the second end of the connecting belt, and the latch is mounted on the housing. The latch is used to latch the connector when the wearable device is in a detection state so that the connector is fixed relative to the housing, and the latch is also used to disengage the connector when the wearable device is in a non-detection state so that the connector can move relative to the housing.

[0008] In this implementation, the locking mechanism can quickly control the elastic connection of the elastic rope to fail by engaging the connecting piece with the locking piece, and can quickly release the control of the elastic rope by releasing the locking piece from engaging the connecting piece, so that the elastic rope can resume elastic connection.

[0009] In some possible implementations, the connector has a plurality of slots arranged at intervals. The plurality of slots are arranged in a direction from the first end of the connector to the second end of the connector. The locking member includes an electric pin, and the latch of the electric pin is used to move toward the connector to insert into the slot, or move away from the connector to disengage from the slot.

[0010] In this implementation, the electric pin is controlled to engage and disengage the connecting piece, which can improve the efficiency of engaging and disengaging the connecting piece, thereby improving the detection efficiency. When the wearable device is in the detection state, the pin is located in the locking hole, which can limit the displacement of the second end of the connecting belt and limit the further elastic deformation of the elastic rope, thereby making the elastic connection of the elastic rope invalid, thereby maintaining a good fit between the main body and the wearing part of the human body, improving the stability of the main body during detection, and improving the accuracy of the detection result.

[0011] In some possible implementations, the diameter of the locking hole is larger than the distance between two adjacent locking holes. The outer diameter of the plug pin of the electric pin is smaller than the inner diameter of the locking hole.

[0012] In this implementation, the diameter of the clamping hole is larger than the spacing between two adjacent clamping holes, so that the clamping hole can occupy more positions in the direction from the first end of the connecting member to the second end of the connecting member, which is conducive to improving the success rate of the plug of the electric pin being inserted into the clamping hole without external interference. The outer diameter of the plug of the electric pin is smaller than the inner diameter of the clamping hole, which reduces or even eliminates the friction between the plug and the inner wall of the clamping hole when the plug is inserted into or out of the clamping hole, which is conducive to the smooth insertion of the plug into the clamping hole and the smooth retraction of the plug from the clamping hole to the pin shell.

[0013] The spacing between two adjacent clamping holes refers to the minimum size of a portion of the connecting member between two adjacent clamping holes in a direction from the first end of the connecting member to the second end of the connecting member.

[0014] In some possible implementations, an end surface of the plugging end of the plug of the electric pin has a chamfer.

[0015] In this implementation, the plugging end of the pin is the end of the pin that is closer to the connector than the pin shell, and a chamfer is set on the end face of the plugging end so that the edge of the end face of the plugging end has a bevel or an arc surface, so that in the process of controlling the insertion of the pin into the card hole, if the chamfer of the end face of the plugging end abuts against the edge of the card hole, the bevel or arc surface of the chamfer can guide the connector to move along the sliding groove relative to the pin until the pin is aligned with the card hole, so that the pin can be inserted into the card hole, thereby improving the fault tolerance of the pin inserting into the card hole, thereby improving the user experience of the wearable device.

[0016] In some possible implementations, the outer diameter of the plug of the electric pin is in the range of 1 mm to 2 mm, the spacing between two adjacent holes is in the range of 0.5 mm to 1 mm, and the inner diameter of the hole is in the range of 1.5 mm to 2.5 mm.

[0017] In this implementation, by setting the outer diameter of the plug within the range of 1 mm to 2 mm, the difference between the outer diameter of the plug and the inner diameter of the card hole can be within a reasonable range, so that the plug can be easily inserted into the card hole, thereby making the wearable device enter the detection state with high efficiency. The size design of the plug can also limit the range of movement of the plug in the card hole when the plug is in the card hole, so that the range of movement of the second end of the connecting belt driven by the connecting member relative to the shell is limited, thereby making the main body and the human body wearing part fit stably when the wearable device is in the detection state, which is beneficial to the stability of the detection, so as to improve the accuracy of the detection.

[0018] In some possible implementations, the shell has a sliding groove, the connecting member is installed in the sliding groove and is slidably connected to the shell, the sliding groove is a flat groove, and the connecting member is in the shape of a plate.

[0019] In this implementation, the connector is slidably connected to the housing through the sliding groove, which improves the flexibility of the relative movement of the connector and the housing. By providing a flat sliding groove and a plate-shaped connector, the space occupied by the sliding groove and the plate-shaped connector in the thickness direction of the main body can be reduced, which is conducive to the lightweight design of the main body. In addition, by providing a flat sliding groove and a plate-shaped connector, the displacement of the connector in the thickness direction of the main body when moving in the sliding groove can also be reduced, which improves the stability of the connector relative to the sliding groove, and is conducive to the clamping member to clamp the connector more stably.

[0020] Among them, the wearable device can design the shape of the sliding groove to match the shape of the connector, so that the groove wall of the sliding groove can limit the connector, thereby preventing the connector from shifting when it moves relative to the shell, and improving the stability of the connector relative to the shell. Among them, the groove width of the sliding groove can be adapted to the width of the connector, for example, the groove width of the sliding groove can be equal to or slightly larger than the width of the connector. At this time, the side wall of the sliding groove can limit the connector, thereby preventing the connector from shifting when it moves relative to the shell, and improving the stability of the connector relative to the shell.

[0021] The elastic rope is located in the sliding groove, and the elastic rope elastically connects the inner wall of the sliding groove and the connecting piece, so that the shell can protect the elastic rope and prevent external debris from entering and affecting the elastic deformation of the elastic rope.

[0022] The sliding groove accommodates at least a portion of the connecting member, thereby providing protection for the connecting member, such as anti-collision, dust-proof, and waterproof.

[0023] The connecting piece blocks the opening of the sliding groove, plays a role of waterproofing and moisture-proofing, reduces the contact between the elastic rope and air and water vapor, thereby preventing the elastic rope from oxidation and corrosion, and can increase the service life of the elastic rope.

[0024] In some possible implementations, the housing includes a first shell and a second shell, the second shell and the electric pin are located in the first shell, the sliding groove is provided in the second shell, and the pin shell of the electric pin is stacked on the top side of the second shell. The plug of the electric pin is used to extend from the pin shell of the electric pin into the second shell and insert into the card hole when the wearable device is in a detection state, and the plug of the electric pin is also used to retract from the second shell to the pin shell and disengage from the card hole when the wearable device is in a non-detection state.

[0025] In this implementation, the second shell and the electric pin are located inside the first shell, so that the elastic rope and the connecting piece can be located inside the first shell, thereby allowing the first shell to form a protection for the electric pin, the elastic rope and the connecting piece, thereby increasing the service life of the electric pin, the elastic rope and the connecting piece, thereby reducing the number of maintenance and replacement times of the electric pin, the elastic rope and the connecting piece, and improving the user experience.

[0026] Among them, the top side of the second shell is the side of the second shell close to the main display surface, that is, the side of the second shell away from the wearing part of the human body when the wearable device is worn.

[0027] In some possible implementations, the end of the second shell is spaced apart from the inner wall of the first shell, and a sealing member is provided between the end of the second shell and the inner wall of the first shell.

[0028] In this implementation, the seal can seal the gap between the end of the second shell and the inner wall of the first shell in the first shell to prevent external water vapor, impurities, etc. from invading the area of ​​the first shell through the connecting belt, thereby protecting electronic devices such as circuit boards and sensors in the first shell.

[0029] In some other possible implementations, the end of the second shell may be flush with the end of the first shell, or the end of the second shell may extend out of the first shell, or the second shell may abut against the inner wall.

[0030] In this possible implementation, a sealed environment can be formed by cooperating the end of the second shell with the first shell, thereby preventing external water vapor, impurities, etc. from invading the area where the connecting belt passes through the first shell.

[0031] In some possible implementations, the main body further includes a sensor, and the sensor is located in the first shell and stacked on the bottom side of the second shell.

[0032] In this implementation, the sensors are stacked on the bottom side of the second shell, so that the sensors can be arranged close to the wearing part of the human body, which is beneficial to improving the accuracy of the sensors in detecting the target parameters.

[0033] Among them, the bottom side of the second shell is the side of the second shell away from the main display surface, that is, the side of the second shell facing the wearing part of the human body when the wearable device is worn.

[0034] In some possible implementations, the housing includes a first shell and a second shell, the second shell is stacked and fixed on the bottom side of the first shell, the sliding groove is provided in the second shell, and the pin shell of the electric pin is accommodated in the first shell. The plug of the electric pin is used to extend from the pin shell of the electric pin into the second shell and insert into the card hole when the wearable device is in a detection state, and the plug of the electric pin is also used to retract from the second shell to the pin shell of the electric pin and disengage from the card hole when the wearable device is in a non-detection state.

[0035] In this implementation, the first shell and the second shell are stacked so that the first shell and the second shell can be assembled in a stacked manner, thereby improving the assembly efficiency of the main body. And because the sliding groove is provided in the second shell, the connecting piece and the elastic rope are both located in the sliding groove and outside the first shell, which is conducive to the maintenance and replacement of the connecting piece and the elastic rope. Because the first shell and the second shell are stacked, the sliding groove can be closer to the wearing part of the human body when the wearable device is worn on the human body, so that the second end of the connecting belt is closer to the wearing part of the human body, thereby reducing the bending degree near the second end of the connecting belt, and can reduce the fatigue risk of the connecting belt near the second end of the connecting belt.

[0036] In some possible implementations, the sensor is located in the second shell.

[0037] In this implementation, the sensor is placed close to the wearable part of the human body when the wearable device is worn on the human body, which is beneficial to improving the detection accuracy of the sensor. The sensor can be arranged at intervals with the sliding groove so that the setting of the sensor does not increase the thickness of the second shell, which is beneficial to the thin and light design of the wearable device. In addition, the sensor is arranged at intervals with the sliding groove, which can reduce the interference of the electric pin on the sensor, improve the signal-to-noise ratio of the signal detected by the sensor, and thus improve the accuracy of the sensor detection.

[0038] The sensor may be located between the sliding groove and the first end of the connecting belt, or the sensor may be arranged around the circumference of the sliding groove.

[0039] In some other possible implementations, the sensor is disposed on the bottom side of the second shell.

[0040] In this implementation, the sensor is brought closer to the wearing part of the human body when the wearable device is worn on the human body, which is beneficial to improving the detection accuracy of the sensor.

[0041] Among them, the sensor can be staggered with the electric pin in the stacking direction of the first shell and the second shell, which can reduce the interference of the electric pin on the sensor, improve the signal-to-noise ratio of the signal detected by the sensor, and thus improve the accuracy of sensor detection.

[0042] In some possible implementations, the locking mechanism includes a connecting rope and a driving member, and the driving member is mounted on the housing. The first end of the connecting rope is connected to the driving member, and the second end of the connecting rope is connected to the second end of the connecting belt. The driving member is used to drive the connecting rope when the wearable device is in a detection state, so that the length of the portion of the connecting rope outside the housing is less than or equal to the length of the elastic rope. The driving member is also used to reversely drive the connecting rope when the wearable device is in a non-detection state, so that the length of the portion of the connecting rope outside the housing is greater than the length of the elastic rope.

[0043] In this implementation, when the wearable device is in a detection state, the driving member drives the connecting rope so that the length of the portion of the connecting rope outside the shell is less than or equal to the length of the elastic rope. Since the connecting rope needs to be pulled to be stretched before the elastic rope is stretched and deformed, the connecting rope forms a restriction on the stretching deformation of the elastic rope, thereby limiting the second end of the connecting belt from moving away from the shell along the extension direction of the connecting belt, which is conducive to the stable wearing of the main body and improves the accuracy of detection. When the wearable device is in a non-detection state, the driving member drives the connecting rope in the reverse direction so that the length of the portion of the connecting rope outside the shell is greater than the length of the elastic rope. Since the connecting rope does not need to be pulled to be stretched before the elastic rope is stretched and deformed, the elastic rope can be stretched and deformed freely before the stretching deformation of the elastic rope is equal to the length of the portion of the connecting rope outside the shell, so that the second end of the connecting belt and the shell are movable and adjustable within a certain range along the extension direction of the connecting belt, thereby improving the wearing comfort of the wearable device.

[0044] Among them, the elastic modulus of the connecting rope is greater than the elastic modulus of the elastic rope, so that the force required for the deformation of the connecting rope is greater than the force required for the deformation of the elastic rope, so that the pulling force required for the tensile deformation of the connecting rope is greater than the pulling force required for the deformation of the elastic rope. When the wearable device is in a detection state, the connection rope increases the restriction on the tensile deformation of the elastic rope, thereby further restricting the second end of the connecting belt from moving away from the shell along the extension direction of the connecting belt, thereby facilitating the stable wearing of the main body and improving the accuracy of the detection. When the wearable device is in a non-detection state, when the elastic rope is subjected to tensile deformation, the maximum size of the tensile deformation of the elastic rope will be limited by the length of the portion of the connecting rope located outside the shell, thereby limiting the tensile deformation range of the elastic rope, thereby making the wearable device comfortable to wear while having good structural strength.

[0045] In some possible implementations, the driving member includes a motor, an output shaft of the motor is connected to the first end of the connecting rope, and is used to wind or unfold the connecting rope.

[0046] In this implementation, the output shaft of the motor is directly connected to the first end of the connecting rope, so that the motor can directly wind or unfold the connecting rope, which simplifies the transmission structure, helps to improve the transmission efficiency and realize the miniaturization design of the driving component.

[0047] In some possible implementations, the driving member includes a motor, a first gear, a second gear, and a transmission shaft. The first gear is sleeved on the output shaft of the motor, and the second gear is transmission-connected to the first gear. The first portion of the transmission shaft is passed through the second gear, and the second portion of the transmission shaft protrudes from the second gear. The first end of the connecting rope is wound around the second portion of the transmission shaft.

[0048] In this implementation, the first gear can be connected to the output shaft of the motor, and the motor drives the first gear to rotate through the output shaft, and drives the second gear to rotate through the first gear. The transmission shaft can be connected to the second gear, and the second gear can drive the transmission shaft to rotate so as to wind the first end of the connecting rope, so that the length of the portion of the connecting rope outside the housing is less than or equal to the length of the elastic rope, so that the elastic connection of the elastic rope fails. The second gear can also drive the transmission shaft to rotate in the opposite direction to unfold the first end of the connecting rope, so that the length of the portion of the connecting rope outside the housing is greater than the length of the elastic rope, so that the elastic rope restores the elastic connection.

[0049] The driving member may further include a third gear, which is disposed between the first gear and the second gear, and the third gear is meshed with the first gear and the second gear respectively. The third gear is provided to facilitate controlling the speed ratio between the output shaft of the motor and the transmission shaft, and to facilitate making the transmission connection between the motor and the transmission shaft more stable, thereby improving the stability of the driving connection rope.

[0050] The surface of the connecting belt can be roughened to increase the surface roughness of the connecting belt, thereby avoiding slippage between the transmission shaft and the connecting belt when the transmission shaft is winding or unwinding the connecting belt, which is beneficial to improving the stability of the driving connecting rope.

[0051] In some possible implementations, the connecting rope is provided with a plurality of meshing holes, which are arranged at intervals along the extending direction of the connecting rope. The second part of the transmission shaft is provided with a plurality of meshing teeth in the circumference, which are arranged at intervals along the circumference of the transmission shaft, and the meshing holes are matched and connected with the meshing teeth.

[0052] In this implementation, the transmission shaft can be connected to the meshing hole on the connecting rope through the meshing teeth, so that when the first end of the connecting rope is wound onto the transmission shaft, the side wall of the meshing hole and the outer peripheral side of the meshing teeth form a limit, which improves the stability of the first end of the connecting rope being wound onto the transmission shaft. In the process of winding the connecting rope, the transmission shaft can clamp the meshing hole on the connecting rope through the meshing teeth to cooperate with the rotation of the transmission shaft to wind up the connecting rope, thereby improving the force of winding up the connecting rope and preventing the connecting rope from slipping during the winding process, which is conducive to the stable operation of the driving member.

[0053] In some possible implementations, the driving member includes a motor, a lead screw and a sleeve. The motor is drivingly connected to the lead screw, the sleeve is sleeved on the lead screw and drivingly connected to the lead screw, and the sleeve is fixedly connected to the first end of the connecting rope. The motor is used to drive the lead screw to rotate, so that the sleeve drives the first end of the connecting rope to move relative to the lead screw.

[0054] In this implementation, the motor drives the lead screw to rotate, so that the sleeve moves relative to the lead screw along the extension direction of the lead screw, thereby driving the first end of the connecting rope to move relative to the lead screw, thereby changing the length of the portion of the connecting rope located outside the housing. By pulling the first end of the connecting rope by the sleeve to change the length of the portion of the connecting rope located outside the housing, there is no need to wind the first end of the connecting rope, which can reduce wrinkles formed on the connecting rope after multiple windings, and can avoid bending fatigue of the connecting rope after multiple windings, thereby increasing the service life of the connecting rope.

[0055] The driving member may further include a plurality of balls. The balls are arranged between the inner side of the sleeve and the outer side of the lead screw, and the balls are located in the guide groove between the sleeve and the lead screw. The motor drives the lead screw to rotate, thereby driving the balls to roll, and the motion force generated by the rolling of the balls drives the sleeve to move relative to the lead screw along the extension direction of the lead screw. Since the rolling friction coefficient of the balls is low, the friction loss of the first end of the connecting rope driven by the driving member is reduced, thereby saving energy and improving the working efficiency of the driving member.

[0056] In some possible implementations, the main body further includes a driving circuit and a processor, the driving circuit is electrically connected to the driving member, the processor is electrically connected to the driving circuit, and the processor is used to control the driving circuit to drive the driving member to drive the connecting rope in response to the detection signal.

[0057] The target parameter detection is performed by actively triggering the detection signal. For example, the detection signal is triggered by a control button so that the processor responds to the detection signal, and the wearable device enters a detection state to detect the target parameter. Alternatively, the detection signal is triggered by touching an operation interface on a display panel of the main body so that the processor responds to the detection signal, and the wearable device enters a detection state to detect the target parameter.

[0058] The detection signal is triggered by a preset scene to detect the target parameter. For example, the detection signal is generated regularly by a preset time, so that the processor responds to the detection signal, and the wearable device enters a detection state to detect the target parameter. The preset time can be one time point or multiple time points.

[0059] The detection signal is triggered by the first parameter so that the processor responds to the detection signal, and the wearable device enters the detection state to detect the second parameter. The first parameter includes the number of steps, speed, acceleration, altitude, sleep duration, etc. The first parameter is a real-time detection parameter, and the second parameter is a parameter detected when the wearable device is in the detection state. The first parameter is only for illustration and does not limit the first parameter. The second parameter may include at least one parameter in the target parameter.

[0060] In some possible implementations, the width of the connecting rope is greater than the width of the elastic rope.

[0061] In this implementation, the connecting rope is set to have a wider width than the elastic rope, so that the connection between the second end of the connecting rope and the shell is more stable, and the connecting rope can provide a better sense of support, which is conducive to improving the wearing feel of the wearable device.

[0062] In some possible implementations, the wearable device includes two elastic cords. The two elastic cords are stacked and spaced apart in a thickness direction of the connecting belt, and the connecting cord is disposed between the two elastic cords.

[0063] In this implementation, the connecting belt is elastically connected to the housing through two elastic ropes, which improves the strength of the elastic connection between the connecting belt and the housing, and can improve the stability of the connection between the connecting belt and the housing. By arranging the connecting rope between the two elastic ropes so that the two elastic ropes are symmetrically arranged compared to the connecting rope, the stability of the elastic deformation of the elastic rope when the connecting belt moves compared to the housing is improved. In addition, the two elastic ropes can also limit the connecting rope to prevent the portion of the elastic rope outside the housing from deviating too much from the connecting belt when it is longer.

[0064] In some possible implementations, the connecting rope is an inelastic member.

[0065] In this implementation, the connecting rope can be an inelastic part, which can better limit the elastic rope from being stretched and deformed when the wearable device is in the detection state, so that the elastic connection of the elastic rope fails, thereby further limiting the second end of the connecting belt from moving away from the shell along the extension direction of the connecting belt, thereby facilitating the stable wearing of the main body and improving the accuracy of the detection. For example, the connecting rope can be an inelastic ultra-thin soft belt. The fact that the connecting rope is an inelastic part does not mean that the connecting rope cannot be deformed at all, but means that the connecting rope is difficult to be stretched and deformed when subjected to force, for example, the elastic modulus of the connecting rope is greater than 1Gpa.

[0066] In some possible implementations, the connecting rope is made of nylon material.

[0067] In this implementation, the connecting rope can be made of nylon material so that the connecting rope has a larger elastic modulus, thereby making the connecting rope less likely to be stretched and deformed under force, thereby better limiting the stretching deformation of the elastic rope when the wearable device is in the detection state, so that the elastic connection of the elastic rope fails, thereby further limiting the movement of the second end of the connecting belt away from the shell along the extension direction of the connecting belt, which is conducive to the stable wearing of the main body and improves the accuracy of detection.

[0068] In some possible implementations, the elastic modulus of the elastic rope is less than or equal to 0.1 MPa.

[0069] In this implementation, the elastic modulus of the elastic cord is less than or equal to 0.1 MPa, so that the elastic cord is more likely to deform when subjected to force, thereby improving the flexibility of adjusting the overall circumference of the wearable device when worn. For example, the elastic modulus of the elastic cord may be, but is not limited to, 0.1 MPa, or 0.08 MPa, or 0.06 MPa, or 0.04 MPa, or 0.02 MPa, or 0.01 MPa, or other values ​​less than 0.1 MPa.

[0070] In some possible implementations, the maximum dimension of the elastic variation of the elastic cord is in the range of 20 mm to 30 mm.

[0071] In this implementation, by setting the maximum size of the elastic change of the elastic rope, when the wearable device is worn, the size change of the circumference of the wearable device through the elastic deformation of the elastic rope is moderate, and it can be better adapted to the wear part of the human body. For example, the maximum size of the elastic change of the elastic rope can be but not limited to 20mm, or 22mm, or 24mm, or 26mm, or 28mm, or 30mm, or other values ​​between 20mm and 30mm. If the maximum size of the elastic change of the elastic rope is less than 20mm, it is easy to cause squeezing when the wearable device is worn on the wear part of the human body, or when the wearable device is worn on the wear part of the human body, it is difficult to overcome the situation of the partial size change area, such as it is difficult to pass through the palm part when worn on the wrist. If the maximum size of the elastic change of the elastic rope is greater than 30mm, it is easy to fall off when the wearable device is worn. For example, when the wearable device 1000 is worn on the wrist and the person is walking, the elastic rope is easy to deform under the action of the weight of the wearable device, the centrifugal force of the person swinging his hand, etc., so that the wearable device is easy to be thrown out through the palm and fall off.

[0072] In some possible implementations, the elastic rope is made of rubber or latex.

[0073] In this implementation, the material of the elastic rope is rubber or latex, so that the elastic rope has strong fatigue resistance and recovery ability, and has good elasticity and flexibility, so that the elastic rope has a good skin-fitting feel and improves wearing comfort.

[0074] In a second aspect, the present application provides a control method for a wearable device, which is applied to any of the wearable devices described above, and the control method for the wearable device includes: in response to a detection signal, controlling the elastic connection of the elastic rope to fail, and fixing the second end of the connecting belt relative to the shell; detecting target parameters; and releasing the control of the elastic rope so that the elastic rope elastically connects the second end of the connecting belt and the shell.

[0075] In the present application, before the wearable device enters the detection state, the elastic connection of the elastic rope is controlled to fail, which can effectively improve the wearing stability of the wearable device after entering the detection state, thereby improving the detection accuracy. After the target parameter detection is completed, the control of the elastic rope is promptly released, so that the elastic rope can restore the elastic connection in time, so that the elasticity between the second end of the connecting belt and the shell can be adjusted, and then the wearing tightness of the wearable device is adaptively adjusted by the elastic rope, thereby improving the wearing comfort of the wearable device.

[0104] Please refer to Figure 1A and Figure 1B , Figure 1A is a schematic diagram of the structure of the wearable device 1000 provided in some embodiments of the present application; Figure 1B yes Figure 1A A schematic diagram of wearing the wearable device 1000 is shown.

[0105] In some embodiments, the wearable device 1000 may include a main body 100 and a connecting band 200. The main body 100 may include a shell 20. The connecting band 200 is connected to both ends of the shell 20, and the connecting band 200 and the shell 20 are connected to form a ring for wearing on a human body. The connecting band 200 may be a cuff or a watch strap, and the connecting band 200 and the shell 20 may be detachably connected or non-detachably connected. Figure 1B The section lines shown are the parts worn by the human body, such as the wrist, arm, etc.

[0106] In some examples, the connecting strap 200 may be a continuous integrated structure, and the connecting strap 200 may include a first end 2001 and a second end 2002. The first end 2001 of the connecting strap 200 is fixedly connected to one end of the housing 20, the second end 2002 of the connecting strap 200 may pass through a watch ring installed at the other end of the housing 20, and the second end 2002 of the connecting strap 200 may be folded back to the middle of the connecting strap 200 for fixing. In this case, the first end 2001 of the connecting strap 200 is the first end 2003 of the connecting strap 200, the connection between the connecting strap 200 and the watch ring is the second end 2004 of the connecting strap, and the length of the connecting strap 200 between the first end 2003 and the second end 2004 is the circumferential length of the connecting strap 200.

[0107] In this embodiment, the second end 2002 of the connecting band 200 and the middle part of the connecting band 200 are fixed in a detachable manner. The positions of the second end 2002 of the connecting band 200 and the middle part of the connecting band 200 can be adjusted to adjust the circumferential length of the connecting band 200 when the wearable device 1000 is worn, thereby adjusting the tightness of the wearable device 1000 when worn.

[0108] In other examples, the connecting band 200 may be a continuous integrated structure, and the connecting band 200 may include a first end and a second end. The first end of the connecting band 200 is fixed to one end of the housing 20, the second end of the connecting band 200 is fixed to the other end of the housing 20, and an adjustment structure is provided in the middle of the connecting band 200. In this embodiment, by adjusting the adjustment structure in the middle of the connecting band 200, the circumferential length of the connecting band 200 when the wearable device 1000 is worn can be adjusted, thereby adjusting the tightness of the wearable device 1000 when worn.

[0109] In some other examples, the connection band 200 may include a first part and a second part, the first part and the second part are detachably connected, the first part is fixed to one end of the housing 20, and the second part is fixed to the other end of the housing 20. In this embodiment, the overlapping portion of the first part and the second part when connected is an overlapping portion, and by adjusting the length of the overlapping portion of the first part and the second part, the circumferential length of the connection band 200 when the wearable device 1000 is worn can be adjusted, thereby adjusting the tightness of the wearable device 1000 when worn.

[0110] Exemplarily, the main body 100 has detection and presentation functions. The main body 100 can be used to detect target parameters and present the detection process and / or detection results of the target parameters.

[0111] The target parameter may include at least one of blood pressure, heart rate, blood oxygen, sleep duration, number of steps, acceleration, and altitude. At this time, the wearable device 1000 may be used as a detection device. For example, the wearable device 1000 is a blood pressure measuring device. The wearable device 1000 may be, but is not limited to, a wearable wrist blood pressure measuring device, an upper arm blood pressure measuring device, or other electronic products with a blood pressure measuring function.

[0112] The presentation of the target parameter by the main body 100 may include at least one of display, light, vibration, and voice.

[0113] Exemplarily, the main body 100 may include one or more control buttons 300, which are mounted on the housing 20. The control button 300 can control the power on and off of the main body 100, or control the on and off of the detection function of the main body 100, or control the type of target parameter detected by the main body 100, or control the time, number of times, duration, etc. of the target parameter detected by the main body 100, or control the information presented by the main body 100, such as display background, display time, type and position of display target parameters, color of light, frequency of vibration, type of voice, etc.

[0114] Please refer to Figures 1A to 2 , Figure 2 yes Figure 1A The working principle diagram of the wearable device 1000 in some embodiments is shown in FIG. The dotted line portion in the figure represents an electrical connection, and the solid line portion represents a structural connection.

[0115] In some embodiments, the wearable device 1000 may further include an elastic cord 30. The main body 100 may further include a locking mechanism 10 mounted on the housing 20.

[0116] For example, the locking mechanism 10 may be at least partially installed inside the housing 20 so that the housing 20 can protect the locking mechanism 10. Alternatively, the locking mechanism 10 may be installed outside the housing 20, which is convenient for maintenance and replacement of the locking mechanism 10.

[0117] Exemplarily, the connecting band 200 includes a first end 2003 and a second end 2004, the first end 2003 of the connecting band 200 is connected to the housing 20, and the second end 2004 of the connecting band 200 is elastically connected to the housing 20 via an elastic rope 30. In this embodiment, the second end 2004 of the connecting band 200 is connected to the housing 20 via an elastic rope 30, and since the elastic rope 30 is stretchable, the relative position between the second end 2004 of the connecting band 200 and the housing 20 is adjustable, so that when the wearable device 1000 is worn, its overall circumference can be adjusted at any time, and can be adaptively adjusted according to the size of the wearing part of the human body, thereby improving the wearing experience of the wearable device 1000.

[0118] In some examples, the length of the connecting band 200 is adjustable. In this embodiment, before the wearable device 1000 is worn, the circumferential length of the connecting band 200 can be lengthened first, so that the wearable device 1000 can be directly worn on the human body along the extension direction of the human body wearing part. After the wearable device 1000 is moved to the human body wearing part, the circumferential length of the connecting band 200 can be shortened so that the wearable device 1000 can be worn on the human body. Similarly, in the process of removing the wearable device 1000, the circumferential length of the connecting band 200 can be lengthened first, so that the wearable device 1000 can be directly removed along the extension direction of the human body wearing part. Among them, the adjustable length of the connecting band 200 can be adjusted by, but not limited to, the buckle structure in the middle of the connecting band 200, the sliding adjustment structure at the end, and other structures.

[0119] In this embodiment, when the wearable device 1000 is worn on the human body, the elastic rope 30 is elastic, so that the wearing tightness of the wearable device 1000 can be adaptively adjusted by the elastic rope 30, thereby improving the wearing comfort.

[0120] In other examples, the elastic cord 30 can change the overall circumference of the wearable device 1000 through elastic deformation to achieve the wearing and removal of the wearable device 1000. During the wearing process of the wearable device 1000, the wearable device 1000 can be directly worn on the human body from the extension direction of the human body wearing part. The elastic cord 30 can adaptively change the overall circumference of the wearable device through elastic deformation, thereby completing the wearing, without disassembling the connecting belt 200 or adjusting the circumferential length of the connecting belt 200, thereby improving the convenience of wearing the wearable device 1000. Similarly, during the removal process of the wearable device 1000, the elastic cord 30 can also adaptively change the overall circumference of the wearable device through elastic deformation, thereby improving the convenience of removing the wearable device 1000.

[0121] It should be noted that the second end 2004 of the connecting belt 200 refers to the connection point between the connecting belt 200 and the elastic cord 30. When the connecting belt 200 is connected to the elastic cord 30 through the end, the end of the connecting belt 200 close to the elastic cord 30 is the second end 2004 of the connecting belt 200. When the connecting belt 200 is partially bent after being connected to the elastic cord 30 and the end is overlapped to other parts of the connecting belt 200, the bending point where the connecting belt 200 and the elastic cord 30 are connected is the second end 2004 of the connecting belt 200. In other words, the second end 2004 of the connecting belt 200 is the end of the connecting belt 200 connected to the elastic cord 30 on the ring when the housing 20, the connecting belt 200 and the elastic cord 30 are connected in sequence to form a closed ring.

[0122] Among them, when the first end 2001 of the connecting belt 200 is connected to the shell 20, the first end 2001 of the connecting belt 200 is the first end 2003 of the connecting belt 200; when the second end 2002 of the connecting belt 200 is connected to the shell 20, the second end 2002 of the connecting belt 200 is the second end 2004 of the connecting belt 200.

[0123] The elastic modulus of the elastic cord 30 may be less than or equal to 0.1 MPa, so that the elastic cord 30 is more likely to deform when subjected to force, thereby improving the flexibility of adjusting the overall circumference of the wearable device 1000 when worn. For example, the elastic modulus of the elastic cord 30 may be, but is not limited to, 0.1 MPa, or 0.08 MPa, or 0.06 MPa, or 0.04 MPa, or 0.02 MPa, or 0.01 MPa, or other values ​​less than 0.1 MPa.

[0124] Among them, the maximum size of the elastic change of the elastic rope 30 can be in the range of 20mm to 30mm. In this embodiment, by setting the maximum size of the elastic change of the elastic rope 30, when the wearable device 1000 is worn, the size change of the circumference of the wearable device 1000 caused by the elastic deformation of the elastic rope 30 is moderate, and it can be better adapted to the wear part of the human body. For example, the maximum size of the elastic change of the elastic rope 30 can be but not limited to 20mm, or 22mm, or 24mm, or 26mm, or 28mm, or 30mm, or other values ​​between 20mm and 30mm. If the maximum size of the elastic change of the elastic rope 30 is less than 20mm, it is easy to cause squeezing when the wearable device 1000 is worn on the wear part of the human body, or when the wearable device 1000 is worn on the wear part of the human body, there is a situation where it is difficult to overcome the partial size change area, for example, it is difficult to pass through the palm part when worn on the wrist. If the maximum dimension of the elastic change of the elastic rope 30 is greater than 30 mm, the wearable device 1000 is easy to fall off when being worn. For example, when the wearable device 1000 is worn on the wrist and the person is walking, the elastic rope 30 is easy to be deformed under the action of the wearable device 1000's own weight, the centrifugal force of the person swinging the hand, etc., thereby causing the wearable device 1000 to be easily thrown out through the palm and fall off.

[0125] The material of the elastic rope 30 may be rubber or latex, so that the elastic rope 30 has strong fatigue resistance and recovery ability, and has good elasticity and flexibility, so that the elastic rope 30 has a good skin-fitting feel and improves wearing comfort.

[0126] Exemplarily, the locking mechanism 10 can be mechanically connected to the second end 2004 of the connecting belt 200. The locking mechanism 10 can control the relative position of the second end 2004 of the connecting belt 200 and the housing 20 through a mechanical structure, thereby controlling the elastic connection between the second end 2004 of the connecting belt 200 and the housing 20 to fail and the second end 2004 of the connecting belt 200 to be fixedly connected to the housing 20.

[0127] It should be noted that the failure of the elastic connection of the elastic rope 30 means that the second end 2004 of the connecting belt 200, the elastic rope 30 and the shell 20 still remain connected in sequence, but the elastic rope 30 cannot be deformed under the drive of the connecting belt 200, or the elastic rope 30 only has a small deformation range under the drive of the connecting belt 200, and the small deformation range of the elastic rope 30 will not affect the fit between the wearable device 1000 and the human body wearing part when it is in the detection state.

[0128] When the wearable device 1000 is in the detection state, the locking mechanism 10 controls the elastic connection of the elastic cord 30 to fail. When the wearable device 1000 is in the non-detection state, the locking mechanism 10 releases the control of the elastic cord 30, so that the elastic cord 30 resumes the elastic connection.

[0129] In this embodiment, the locking mechanism 10 mechanically controls the connection belt 200 to achieve control of the failure of the elastic connection of the elastic cord 30, so that the wearable device 1000 can achieve the second end 2004 of the connection belt 200 fixed relative to the housing 20 in the detection state, which is conducive to the entire connection belt 200 being stably attached to the wearing part of the human body, so that the main body 100 can be worn stably to ensure the detection accuracy. Among them, when the elastic connection of the elastic cord 30 fails, it can be said that the connection belt 200 has no wearing elasticity and the connection belt 200 cannot be stretched.

[0130] In addition, the locking mechanism 10 mechanically controls the connection belt 200 to control the elastic connection of the elastic cord 30, so that when the wearable device 1000 is in a non-detection state, the second end 2004 of the connection belt 200 can move relative to the housing 20 to achieve adjustable wearing circumference of the wearable device 1000, thereby improving wearing comfort. Therefore, the locking mechanism 10 is used in this embodiment to achieve stable wearing of the wearable device 1000 in a detection state to ensure accurate detection, and adjustable wearing in a non-detection state to ensure comfortable wearing. Among them, when the elastic cord 30 is elastically connected to the connection belt 200 and the housing 20, it can be said that the connection belt 200 has wearing elasticity and is stretchable.

[0131] In some embodiments, the control method of the wearable device 1000 may include steps S10, S20 and S30.

[0132] S10 , in response to the detection signal, the elastic connection of the elastic rope 30 is controlled to fail, and the second end 2004 of the connecting belt 200 is fixed relative to the housing 20 .

[0133] In this embodiment, before the wearable device 1000 enters the detection state, the locking mechanism 10 first controls the elastic connection of the elastic rope 30 to fail, which can effectively improve the wearing stability of the wearable device 1000 after entering the detection state, thereby improving the detection accuracy.

[0134] The detection signal may be, but is not limited to, automatically triggered or actively triggered. Automatic triggering may include triggering at a set time, triggering in a set scene, etc. Active triggering may include triggering by touching a control key on the main body 100, triggering by sending a signal to the main body 100 using a terminal, etc.

[0135] S20, detecting target parameters.

[0136] In this embodiment, the target parameter is detected while the elastic rope 30 is in a failed state. The target parameter may include at least one of blood pressure, heart rate, blood oxygen, sleep duration, number of steps, acceleration, and altitude.

[0137] S30 , releasing the control of the elastic rope 30 , so that the elastic rope 30 elastically connects the second end 2004 of the connecting belt 200 and the housing 20 .

[0138] In this embodiment, after the target parameter detection is completed, the control of the elastic rope 30 is released in time, so that the elastic rope 30 can restore the elastic connection in time, so that the elasticity between the second end 2004 of the connecting belt 200 and the shell 20 is adjustable, and the wearing tightness of the wearable device is adaptively adjusted by the elastic rope 30, thereby improving the wearing comfort of the wearable device 1000.

[0139] In some embodiments, the main body 100 may include a processor 40 and a drive circuit 50. The drive circuit 50 is electrically connected to the locking mechanism 10. The processor 40 is electrically connected to the drive circuit 50, and the processor 40 is used to respond to the detection signal and control the drive circuit 50 to drive the locking mechanism 10 to control the second end 2004 of the connecting belt 200, so as to control the elastic connection between the second end 2004 of the connecting belt 200 and the housing 20 to fail. The processor 40 is also used to respond to the detection completion signal and control the drive circuit 50 to drive the locking mechanism 10 to control the second end 2004 of the connecting belt 200, so as to control the elastic connection between the second end 2004 of the connecting belt 200 and the housing 20.

[0140] Exemplarily, the target parameter detection is performed by actively triggering the detection signal. For example, the detection signal is triggered by the control button 300, so that the processor 40 responds to the detection signal, and the wearable device 1000 enters the detection state to perform the target parameter detection. Alternatively, the detection signal is triggered by touching the operation interface on the display panel of the main body 100, so that the processor 40 responds to the detection signal, and the wearable device 1000 enters the detection state to perform the target parameter detection.

[0141] Exemplarily, a detection signal is triggered by a preset scene to detect the target parameter. For example, a detection signal is generated regularly by a preset time, so that the processor 40 responds to the detection signal, and the wearable device 1000 enters a detection state to detect the target parameter. The preset time can be one time point or multiple time points.

[0142] Alternatively, a detection signal is triggered by the first parameter so that the processor 40 responds to the detection signal, and the wearable device 1000 enters a detection state to detect the second parameter. The first parameter includes steps, speed, acceleration, altitude, sleep duration, etc. It should be noted that the first parameter is a real-time detection parameter, and the second parameter is a parameter detected when the wearable device 1000 is in the detection state. The above first parameter is only for illustration and does not limit the first parameter. The above second parameter may include at least one parameter in the target parameter.

[0143] In other embodiments, the locking mechanism 10 can also be actively triggered by a mechanical transmission structure. For example, the control button 300 can be connected to the locking mechanism 10. The control button 300 can drive the locking mechanism 10 to move, thereby realizing the control of the connecting belt 200 by the locking structure, and then realizing the elastic connection control of the elastic rope 30 by the locking mechanism 10. In this embodiment, the locking mechanism 10 is directly controlled by the control button 300, which is simple to operate, and the physical button can bring a damping feeling when pressed, thereby improving the user experience.

[0144] Exemplarily, the locking mechanism 10 is transmission-connected to a control button 300. By pressing the control button 300 once, the locking mechanism 10 can control the elastic connection of the elastic cord 30 to fail, and by pressing the control button 300 again, the locking mechanism 10 can release the control of the elastic cord 30, so that the elastic connection of the elastic cord 30 is restored. The elastic connection of the elastic cord 30 is controlled by a control button 300, which is convenient and quick to operate. For example, the locking mechanism 10 and the control button 300 can be transmission-connected via a spring reset structure.

[0145] Exemplarily, the locking mechanism 10 is transmission-connected to two control buttons 300. By pressing one of the control buttons 300, the locking mechanism 10 can be driven to control the elastic connection of the elastic cord 30 to fail, and by pressing the other control button 300, the locking mechanism 10 can be driven to release the control of the elastic cord 30, so that the elastic cord 30 can be restored to elastic connection.

[0146] It can be understood that in some embodiments, the main body 100 may also include more or fewer components than those described above, and the embodiments of the present application do not strictly limit this.

[0147] See also Figure 3 , Figure 3 yes Figure 1A The structure diagram of the locking mechanism 10 in the wearable device 1000 in some embodiments is shown.

[0148] In some embodiments, the locking mechanism 10 may include a connector 2 and a locking member 1. The connector 2 may include a first end 21 and a second end 22. The first end 21 of the connector 2 is connected to the elastic rope 30, and the second end 22 of the connector 2 is connected to the second end 2004 of the connecting belt 200. The locking member 1 is installed on the housing 20. The locking member 1 is used to lock the connector 2 when the wearable device 1000 is in a detection state, so that the connector 2 is fixed relative to the housing 20. The wearable device 1000 in the detection state may include the process from the wearable device 1000 responding to the detection signal to the wearable device 1000 completing the detection. The locking member 1 is also used to disengage the connector 2 when the wearable device 1000 is in a non-detection state, so that the connector 2 can move relative to the housing 20. The locking method of the locking member 1 and the connector 2 may be, but is not limited to, a limit locking connection, a friction locking connection, etc.

[0149] In this embodiment, the locking mechanism 10 can quickly control the elastic connection failure of the elastic rope 30 by locking the connecting member 2 with the locking member 1, and can quickly release the control of the elastic rope 30 by releasing the locking of the connecting member 2 by the locking member 1, so that the elastic rope 30 can restore the elastic connection.

[0150] It should be noted that Figure 3 In the figure, the connecting member 2 is provided with a hole, and the locking member 1 is locked into the hole of the connecting member 2 to realize the locking connection between the locking member 1 and the connecting member 2. The embodiment of the present application does not limit the specific locking method between the locking member 1 and the connecting member 2. Figure 3 The width of the middle connecting belt 200 is only for illustration and does not limit the width of the connecting belt 200 . For example, the connecting belt 200 may be the same width as the shell 20 , or the connecting belt 200 may be wider than the shell 20 .

[0151] Exemplarily, the connector 2 can be movably mounted on the housing 20. The connector 2 can be integrally mounted inside the housing 20, or a portion of the connector 2 is located inside the housing 20, and another portion of the connector 2 protrudes from the housing 20, or the connector 2 is mounted on one side of the housing 20.

[0152] The two ends of the connector 2 may be provided with a first lug and a second lug, in which case the first lug is the first end 21 of the connector 2, and the second lug is the second end 22 of the connector 2. The first lug is fixedly connected to the elastic cord 30, and the second lug is connected to the second end 2004 of the connecting belt 200. The first lug can improve the connection stability between the connector 2 and the elastic cord 30, and the second lug can improve the connection stability between the connector 2 and the connecting belt 200. In addition, the connecting belt 200 can pass through the second lug to adjust the length of the connecting belt 200 for wearing, and the portion where the connecting belt 200 is connected to the second lug is the second end 2004 of the connecting belt 200.

[0153] See also Figure 4A , Figure 4A yes Figure 3 The shown figure is a schematic diagram of the cross-sectional structure of the wearable device 1000 in some embodiments.

[0154] In some embodiments, the housing 20 may have a sliding groove 201. For example, the housing 20 may include a first housing 20a and a second housing 20b, the second housing 20b is located inside the first housing 20a, and the sliding groove 201 is provided in the second housing 20b. The connector 2 may be installed in the sliding groove 201 and slidably connected to the second housing 20b of the housing 20.

[0155] In this embodiment, the connector 2 is slidably connected to the housing 20 via the sliding groove 201, which improves the flexibility of the relative movement between the connector 2 and the housing 20. In addition, the wearable device 1000 can be designed to match the shape of the sliding groove 201 with the shape of the connector 2, so that the groove wall of the sliding groove 201 can limit the connector 2, thereby preventing the connector 2 from deviating when moving relative to the housing 20, and improving the stability of the connector 2 moving relative to the housing 20. The sliding groove 201 accommodates at least part of the connector 2, which can provide protection for the connector 2, such as anti-collision, dustproof, waterproof, etc.

[0156] Exemplarily, the elastic cord 30 is located in the sliding groove 201, and the elastic cord 30 elastically connects the inner wall of the sliding groove 201 and the connecting member 2. By arranging the elastic cord 30 in the sliding groove 201, the housing 20 can protect the elastic cord 30 and prevent external debris from entering and affecting the elastic deformation of the elastic cord 30.

[0157] The connecting member 2 blocks the opening of the sliding groove 201 to play a waterproof and moisture-proof role, reducing the contact between the elastic rope 30 and air and water vapor, thereby preventing the elastic rope 30 from oxidation and corrosion, and can increase the life of the elastic rope 30.

[0158] Exemplarily, the sliding groove 201 may be a flat groove, and the connecting member 2 may be in the shape of a plate. By providing the flat sliding groove 201 and the plate-shaped connecting member 2, the space occupied by the sliding groove 201 and the plate-shaped connecting member 2 in the thickness direction of the main body 100 can be reduced, thereby facilitating a thin and light design of the main body 100. In addition, by providing the flat sliding groove 201 and the plate-shaped connecting member 2, the displacement of the connecting member 2 in the thickness direction of the main body 100 when the connecting member 2 moves in the sliding groove 201 can also be reduced, thereby improving the stability of the connecting member 2 relative to the sliding groove 201, and facilitating the clamping member 1 to clamp the connecting member 2 more stably.

[0159] Exemplarily, the width of the sliding groove 201 can be adapted to the width of the connecting member 2, for example, the width of the sliding groove 201 can be equal to or slightly larger than the width of the connecting member 2. At this time, the side wall of the sliding groove 201 can limit the connecting member 2, thereby preventing the connecting member 2 from deviating when moving relative to the housing 20, thereby improving the stability of the connecting member 2 moving relative to the housing 20.

[0160] The sliding groove 201 and the connecting member 2 may be surface treated to improve the wear resistance therebetween, or a lubricating material may be added between the sliding groove 201 and the connecting member 2 to improve the wear resistance therebetween.

[0161] In some embodiments, the locking member 1 may include an electric pin 11. In this embodiment, the electric pin 11 is controlled to lock and release the connection member 2, thereby improving the efficiency of locking and releasing the connection member 2, thereby improving the detection efficiency.

[0162] The electric pin 11 is located in the first shell 20a. The electric pin 11 is stacked on the top side of the second shell 20b. In this embodiment, the second shell 20b and the electric pin 11 are located in the first shell 20a, so that the elastic rope 30 and the connecting member 2 can be located in the first shell 20a, so that the first shell 20a forms a protection for the electric pin 11, the elastic rope 30 and the connecting member 2, so as to increase the service life of the electric pin 11, the elastic rope 30 and the connecting member 2, thereby reducing the number of repairs and replacements of the electric pin 11, the elastic rope 30 and the connecting member 2, and improving the user experience.

[0163] It should be noted that the top side of the second shell 20b is the side of the second shell 20b close to the display surface of the main body 100, that is, the side of the second shell 20b away from the wearing part of the human body when the wearable device 1000 is worn.

[0164] Exemplarily, the connector 2 has a plurality of slots 23 arranged at intervals, and the plurality of slots 23 are arranged in a direction from the first end 21 of the connector 2 to the second end 22 of the connector 2. The locking member 1 includes an electric pin 11, which is used to lock the connector 2 when the wearable device 1000 is in a detection state, and the electric pin 11 is used to detach the connector 2 when the wearable device 1000 is in a non-detection state.

[0165] The diameter of the locking hole 23 may be greater than the spacing between two adjacent locking holes 23, so that the locking hole 23 can occupy more positions in the direction from the first end 21 of the connecting member 2 to the second end 22 of the connecting member 2, which is conducive to improving the success rate of inserting the plug 112 of the electric pin 11 into the locking hole 23 without external interference. It can be understood that the locking of the plug 112 of the electric pin 11 with the locking hole 23 can be, but not limited to, first aligning the plug 112 of the electric pin 11 with the locking hole 23, and then controlling the plug 112 of the electric pin 11 to extend into the locking hole 23, or first controlling the plug 112 of the electric pin 11 to move toward the direction of the connecting member 2, so that the plug 112 of the electric pin 11 just extends into the locking hole 23 or the plug 112 of the electric pin 11 abuts against the surface of the connecting member 2, and when the plug 112 of the electric pin 11 abuts against the surface of the connecting member 2, the connecting member 2 is adjusted to allow the plug 112 of the electric pin 11 to extend into the locking hole 23.

[0166] It should be noted that the spacing between two adjacent locking holes 23 refers to the minimum size of the portion of the connector 2 between two adjacent locking holes 23 along the direction from the first end 21 of the connector 2 to the second end 22 of the connector 2 .

[0167] The inner diameter of the clamp hole 23 (see Figure 4A D1) in the range of 1.5 mm to 2.5 mm, for example, the inner diameter of the hole 23 can be but is not limited to 1.5 mm, or 1.7 mm, or 1.9 mm, or 2.1 mm, or 2.3 mm, or 2.5 mm, or other values ​​between 1.5 mm and 2.5 mm.

[0168] The distance between two adjacent holes 23 (see Figure 4A L1) in the range of 0.5 mm to 1 mm, for example, the spacing between two adjacent card holes 23 can be but is not limited to 0.5 mm, or 0.6 mm, or 0.7 mm, or 0.8 mm, or 0.9 mm, or 1 mm, or other values ​​between 0.5 mm and 1 mm.

[0169] It should be noted that the card hole 23 may be, but not limited to, a through hole, a groove, etc. The shape of the opening of the card hole 23 toward the electric pin 11 may be, but not limited to, a circle, a square, a diamond, an ellipse, etc. It can be understood that the embodiment of the present application does not limit the specific form and opening shape of the card hole 23.

[0170] Exemplarily, the electric pin 11 may include a pin shell 111 and a latch 112. The pin shell 111 is stacked on the top side of the second shell 20b, and the latch 112 is used to extend from the pin shell 111 into the second shell 20b and insert into the card hole 23 when the wearable device 1000 is in the detection state. The latch 112 is also used to retract from the second shell 20b to the pin shell 111 and disengage from the card hole 23 when the wearable device 1000 is in the non-detection state. The connector 2 is fixed by inserting the latch 112 into the card hole 23. The fixing method is simple and efficient, which is conducive to quickly clamping the connector 2 when the wearable device 1000 needs to enter the detection state, and quickly unlocking the clamping of the connector 2 after the wearable device 1000 is detected, thereby improving the detection efficiency.

[0171] Among them, the outer diameter of the pin 112 of the electric pin 11 is smaller than the inner diameter of the hole 23, which reduces or even eliminates the friction between the pin 112 and the inner wall of the hole 23 when the pin 112 is inserted into the hole 23 or detached from the hole 23, which is conducive to the pin 112 smoothly extending into the hole 23 and the pin 112 smoothly retracting from the hole 23 to the pin shell 111.

[0172] The outer diameter of the latch pin 112 (see Figure 4A D2 in the figure is in the range of 1mm to 2mm. By setting the outer diameter of the plug 112 in the range of 1mm to 2mm, the difference between the outer diameter of the plug 112 and the inner diameter of the card hole 23 can be within a reasonable range, so that the plug 112 can be easily inserted into the card hole 23, thereby making the wearable device 1000 enter the detection state with high efficiency. The size design of the plug 112 can also make the range of movement of the plug 112 in the card hole 23 limited when the plug 112 is located in the card hole 23, so that the range of movement of the second end 2004 of the connecting belt 200 driven by the connecting member 2 relative to the housing 20 is limited, thereby making the main body 100 and the human body wearing part fit stably when the wearable device 1000 is in the detection state, which is beneficial to the stability of the detection and improves the accuracy of the detection. For example, the outer diameter of the plug 112 can be, but is not limited to, 1mm, or 1.2mm, or 1.4mm, or 1.6mm, or 1.8mm, or 2mm, or other values ​​between 1mm and 2mm.

[0173] The end face of the plug end of the plug pin 112 has a chamfer. The plug end of the plug pin 112 is the end of the plug pin 112 that is closer to the connector 2 than the pin housing 111. By setting a chamfer on the end face of the plug end so that the edge of the end face of the plug end has a bevel or arc surface, in the process of controlling the plug pin 112 to be inserted into the card hole 23, if the chamfer of the end face of the plug end abuts against the edge of the card hole 23, the bevel or arc surface of the chamfer can guide the connector 2 to move relative to the plug pin 112 along the sliding groove 201 until the plug pin 112 is aligned with the card hole 23, so that the plug pin 112 can be inserted into the card hole 23, thereby improving the fault tolerance of the plug pin 112 inserting into the card hole 23, thereby improving the user experience of the wearable device 1000.

[0174] Please refer to Figure 4B and Figure 4C , Figure 4B yes Figure 4A The structural schematic diagram of the wearable device 1000 shown is in a detection state; Figure 4C yes Figure 4A The structure diagram of the wearable device 1000 is shown in a non-detection state.

[0175] In some embodiments, when the wearable device 1000 is in the detection state, the latch 112 is located in the latch hole 23, the latch 112 forms a limit on the connector 2, and the elastic connection of the elastic cord 30 fails. When the wearable device 1000 is in the non-detection state, the latch 112 is located outside the latch hole 23, and the elastic cord 30 is elastically connected to the connector 2 and the second shell 20b.

[0176] When the wearable device 1000 is in the detection state, please refer to Figure 4B In the direction from the first end 21 of the connector 2 to the second end 22 of the connector 2, the latch 112 can abut against the inner side wall of the locking hole 23 to limit the connector 2, thereby limiting the displacement of the connector 2. Since the connector 2 connects the elastic cord 30 and the second end 2004 of the connecting belt 200, the latch 112 located in the locking hole 23 can limit the displacement of the second end 2004 of the connecting belt 200 and limit the elastic cord 30 from further elastic deformation, thereby making the elastic connection of the elastic cord 30 invalid, thereby maintaining a good fit between the main body 100 and the wearing part of the human body, improving the stability of the main body 100 during detection, and improving the accuracy of the detection result.

[0177] It should be noted that the pin 112 restricts the elastic cord 30 from further elastic deformation, which means that the elastic cord 30 can be further deformed within a limited range and will not affect the fit between the main body 100 and the wear part of the human body. Among them, the elastic cord 30 is completely unable to undergo further elastic deformation, which is also within the protection scope of this embodiment.

[0178] When the wearable device 1000 is in a non-detection state, please refer to Figure 4C , in the direction from the first end 21 of the connector 2 to the second end 22 of the connector 2, the latch 112 is out of contact with the connector 2, so that the connector 2 can move relative to the second shell 20b along the sliding groove 201. Since the connector 2 connects the elastic cord 30 and the second end 2004 of the connecting belt 200, the connecting belt 200 can drive the connector 2 to move through the second end 2004 of the connecting belt 200, thereby driving the elastic cord 30 to elastically deform within the range of the elastic cord 30, thereby removing the restriction on the body 100 fitting the wearing part of the human body, improving the wearing comfort, and improving the user experience.

[0179] Please refer again Figure 4A In some embodiments, the end of the second shell 20b is spaced apart from the inner wall of the first shell 20a, and a sealing member is provided between the end of the second shell 20b and the inner wall of the first shell 20a.

[0180] In this embodiment, the seal can seal the gap between the end of the second shell 20b and the inner wall of the first shell 20a in the first shell 20a to prevent external water vapor, impurities, etc. from invading the area of ​​the first shell 20a through the connecting band 200, thereby protecting electronic devices such as circuit boards and sensors 60 in the first shell 20a.

[0181] Exemplarily, the first shell 20a may include a first end and a second end, and the second shell 20b may include a first inner wall and a second inner wall. The first end 2003 of the connecting belt 200 passes through the first inner wall and is connected to the first end of the second shell 20b, the second end 2004 of the connecting belt 200 passes through the second inner wall and is connected to the connecting member 2, and the opening of the sliding groove 201 is located at the second end of the second shell 20b. The sealing member is sealingly connected between the first inner wall and the first end of the second shell 20b, and the sealing member is arranged around the first end 2003 of the connecting belt 200. The sealing member is also sealingly connected between the second inner wall and the second end of the second shell 20b, and the sealing member is arranged around the second end 2004 of the connecting belt 200.

[0182] In other embodiments, the end of the second shell 20b may be flush with the end of the first shell 20a, or the end of the second shell 20b may extend out of the first shell 20a, or the second shell 20b may abut against the inner wall. In this embodiment, the end of the second shell 20b is arranged in cooperation with the first shell 20a to form a sealed environment, thereby preventing external water vapor, impurities, etc. from invading the area of ​​the connecting belt 200 through the first shell 20a.

[0183] In some embodiments, the first end 2003 of the connecting band 200 is fixedly connected to the outside of the first shell 20a to reduce the opening of the first shell 20a, thereby improving the sealing of the first shell 20a. Alternatively, the first end 2003 of the connecting band 200 passes through the first shell 20a and is fixedly connected to the second shell 20b, so as to improve the connection stability between the connecting band 200 and the shell 20, and facilitate the symmetrical arrangement of the first end 2003 of the connecting band 200 and the second end 2004 of the connecting band 200, thereby improving the overall stability of the wearable device 1000.

[0184] In some embodiments, the main body 100 may further include a sensor module, which may include one or more sensors 60. At least one sensor 60 is located in the first shell 20a and stacked on the bottom side of the second shell 20b. The bottom side of the second shell 20b is the side of the second shell 20b facing away from the display surface of the main body 100, that is, the side of the second shell 20b facing the wearing part of the human body when the wearable device 1000 is worn.

[0185] In this embodiment, the sensor 60 is stacked on the bottom side of the second shell 20b, so that the sensor 60 can be arranged close to the wearing part of the human body, which is beneficial to improving the accuracy of the sensor 60 in detecting the target parameter.

[0186] Exemplarily, the sensor 60 may abut between the bottom side of the second shell 20 b and the inner wall of the first shell 20 a , so that the sensor 60 is clamped by the inner wall of the first shell 20 a and the second shell 20 b , thereby improving the structural stability of the sensor 60 .

[0187] Among them, the sensor 60 can be used for but not limited to detecting target parameters such as blood pressure, heart rate, blood oxygen, sleep duration, number of steps, acceleration, etc.

[0188] Exemplarily, other sensors 60 in the sensor module may be disposed at other locations to detect other parameters. In the embodiment of the present application, the locations of the other sensors 60 in the sensor module and the parameters to be detected are not limited.

[0189] Please refer to FIG. 5A to FIG. 5C , Figure 5A yes Figure 3 Schematic diagram of the cross-sectional structure of the wearable device 1000 in other embodiments; Figure 5B yes Figure 5A The structural schematic diagram of the wearable device 1000 shown is in a detection state; Figure 5C yes Figure 5A The structure diagram of the wearable device 1000 is shown in a non-detection state. Figure 5A The wearable device 1000 of the illustrated embodiment may include Figure 4AMost of the technical features of the wearable device 1000 of the illustrated embodiment are described below mainly in terms of the differences between the two, and most of the same contents between the two are not repeated here.

[0190] In some embodiments, the housing 20 may include a first housing 20a and a second housing 20b that are stacked. For example, the second housing 20b may be fixed to the bottom side of the first housing 20a. The sliding groove 201 may be provided in the second housing 20b, and the pin housing 111 of the electric pin 11 is accommodated in the first housing 20a.

[0191] In this embodiment, the first shell 20a and the second shell 20b are stacked so that the first shell 20a and the second shell 20b can be assembled in a stacked manner, thereby improving the assembly efficiency of the main body 100. In addition, since the sliding groove 201 is provided in the second shell 20b, the connecting member 2 and the elastic rope 30 are both located in the sliding groove 201 and outside the first shell 20a, which is convenient for the maintenance and replacement of the connecting member 2 and the elastic rope 30.

[0192] In addition, in this embodiment, since the first shell 20a and the second shell 20b are stacked, the sliding groove 201 can be closer to the wearing part of the human body when the wearable device 1000 is worn on the human body, so that the second end 2004 of the connecting belt 200 is closer to the wearing part of the human body, thereby reducing the bending degree near the second end 2004 of the connecting belt 200, and can reduce the fatigue risk of the connecting belt 200 near the second end 2004 of the connecting belt 200.

[0193] Exemplarily, the first end 2003 of the connecting band 200 is fixedly connected to the second shell 20b, so that when the wearable device 1000 is worn on a human body, the first end 2003 of the connecting band 200 can be closer to the wearing part of the human body, thereby reducing the bending degree near the first end 2003 of the connecting band 200, and reducing the fatigue risk of the connecting band 200 near the first end 2003 of the connecting band 200. In addition, the first end 2003 of the connecting band 200 is fixedly connected to the second shell 20b, which is conducive to the symmetrical arrangement of the first end 2003 of the connecting band 200 and the second end 2004 of the connecting band 200, so as to improve the overall stability of the wearable device 1000. In some other embodiments, the first end 2003 of the connecting band 200 can also be fixedly connected to the first shell 20a.

[0194] In some embodiments, the plug 112 of the electric pin 11 is used to extend from the pin housing 111 of the electric pin 11 into the second shell 20b when the wearable device 1000 is in the detection state, and to be inserted into the locking hole 23. The plug 112 of the electric pin 11 is also used to retract from the second shell 20b to the pin housing 111 of the electric pin 11 and to be disengaged from the locking hole 23 when the wearable device 1000 is in the non-detection state.

[0195] It should be noted that Figure 5B , Figure 5C The snap-fitting mode between the electric pin 11 and the connector 2 in the wearable device 1000 of the embodiment shown is similar to Figure 4B , Figure 4C The snap-fitting manner of the electric pin 11 and the connector 2 in the wearable device 1000 of the illustrated embodiment is the same and will not be described in detail herein.

[0196] Please refer to FIG. 6A to FIG. 6C , Fig. 6A yes Figure 3 Schematic diagram of the cross-sectional structure of the wearable device 1000 in some other embodiments; Figure 6B yes Fig. 6A The schematic diagram of the positional relationship between the sensor 60 in the wearable device 1000 and the sliding slot 201 in some embodiments is shown; Figure 6C yes Figure 3 The wearable device 1000 is shown as a schematic diagram of a cross-sectional structure in some further embodiments.

[0197] In some embodiments, the sensor 60 may be located in the second shell 20b. The sensor 60 is located in the second shell 20b so that the sensor 60 is close to the wearing part of the human body when the wearable device 1000 is worn on the human body, which is conducive to improving the detection accuracy of the sensor 60.

[0198] For example, see Fig. 6A and Figure 6B , the sensor 60 can be arranged at intervals with the sliding groove 201, so that the arrangement of the sensor 60 does not increase the thickness of the second shell 20b, which is conducive to the thin and light design of the wearable device 1000. In addition, the sensor 60 is arranged at intervals with the sliding groove 201, which can reduce the interference of the electric pin 11 on the sensor 60, improve the signal-to-noise ratio of the signal detected by the sensor 60, and thus improve the accuracy of the detection of the sensor 60.

[0199] The sensor 60 may be located between the sliding groove 201 and the first end 2003 of the connecting belt 200 , or the sensor 60 may be disposed around the circumference of the sliding groove 201 .

[0200] For example, see Figure 6C , the sensor 60 is arranged on the bottom side of the second shell 20b, so that the sensor 60 is closer to the wearing part of the human body when the wearable device 1000 is worn on the human body, which is conducive to improving the detection accuracy of the sensor 60. Among them, the sensor 60 can be staggered with the electric pin 11 in the stacking direction of the first shell 20a and the second shell 20b, which can reduce the interference of the electric pin 11 on the sensor 60, improve the signal-to-noise ratio of the signal detected by the sensor 60, and thus improve the detection accuracy of the sensor 60.

[0201] Please refer to 7A to 7C , Fig. 7Ayes Figure 1A The structural schematic diagram of the locking mechanism 10 in the wearable device 1000 in other embodiments is shown; Figure 7B yes Fig. 7A The structural schematic diagram of the wearable device 1000 shown is in a detection state; Figure 7C yes Fig. 7A The structure diagram of the wearable device 1000 is shown in a non-detection state.

[0202] In some embodiments, the locking mechanism 10 may include a connecting rope 12 and a driving member 13. The driving member 13 is mounted on the housing 20. The connecting rope 12 may include a first end 121 and a second end 122. The first end 121 of the connecting rope 12 is connected to the driving member 13, and the second end 122 of the connecting rope 12 is connected to the second end 2004 of the connecting belt 200.

[0203] Exemplarily, the driving member 13 can be installed inside the housing 20, and the first end 121 of the connecting rope 12 passes through the housing 20 and is connected to the driving member 13. In this embodiment, the driving member 13 is installed inside the housing 20, so that the housing 20 can protect the driving member 13, for example, to prevent external water vapor from invading, damaging the circuit of the driving member 13 and causing a circuit break or corrosion, and to prevent external impurities from entering the driving structure of the driving member 13 and hindering the movement of the driving member 13.

[0204] Alternatively, the driver 13 can be installed outside the housing 20 and stacked with the housing 20. By installing the driver 13 outside the housing 20, the driver 13 can be quickly disassembled and assembled, which is conducive to the maintenance and replacement of the driver 13, and is also conducive to realizing the customized replacement of the driver 13, and different driver 13 can be customized according to different usage scenarios or preferences.

[0205] The driving member 13 may be, but is not limited to, driving the first end 121 of the connecting rope 12 by winding, pulling, etc., so as to change the length of the portion of the connecting rope 12 between the second end 2004 of the connecting belt 200 and the housing 20. By driving the connecting rope 12 or driving the connecting rope 12 in reverse by the driving member 13 to adjust the length of the portion of the connecting rope 12 between the second end 2004 of the connecting belt 200 and the housing 20, the elastic deformation capability of the elastic rope 30 can be changed.

[0206] The following text uses the case where the driving member 13 is installed inside the housing 20 for illustration; in the following text, the length of the portion of the connecting rope 12 located between the second end 2004 of the connecting belt 200 and the housing 20 is the length of the portion of the connecting rope 12 located outside the housing 20. It can be understood that when the driving member 13 is installed outside the housing 20, the locking mechanism 10 can also adopt the solution or similar solution of the embodiment of controlling the elastic connection failure and restoration of the elastic connection of the elastic rope 30 when the driving member 13 is installed inside the housing 20.

[0207] When the wearable device 1000 is in the detection state, please refer to Figure 7B , the driving member 13 drives the connecting rope 12 so that the length of the portion of the connecting rope 12 outside the housing 20 is less than or equal to the length of the elastic rope 30. In this embodiment, since the connecting rope 12 needs to be pulled to be stretched before the elastic rope 30 is stretched and deformed, the connecting rope 12 forms a restriction on the stretching deformation of the elastic rope 30, thereby restricting the second end 2004 of the connecting belt 200 from moving away from the housing 20 along the extension direction of the connecting belt 200, which is conducive to the stable wearing of the main body 100 and improves the accuracy of detection.

[0208] When the wearable device 1000 is in a non-detection state, please refer to Figure 7C , the driving member 13 drives the connecting rope 12 in the reverse direction, so that the length of the portion of the connecting rope 12 outside the housing 20 is greater than the length of the elastic rope 30. In this embodiment, since the connecting rope 12 does not need to be pulled to be stretched and deformed before the elastic rope 30 is stretched and deformed, the elastic rope 30 can be stretched and deformed freely before the elastic rope 30 is stretched and deformed to the same length as the portion of the connecting rope 12 outside the housing 20, so that the second end 2004 of the connecting belt 200 and the housing 20 can be adjusted within a certain range along the extension direction of the connecting belt 200, thereby improving the wearing comfort of the wearable device 1000.

[0209] It should be noted that, in the embodiment of the present application, the length of the elastic rope 30 refers to the length of the elastic rope 30 when it is not stretched and deformed.

[0210] The connecting rope 12 may be, but is not limited to, a rope-shaped, belt-shaped, column-shaped, etc. The embodiment of the present application does not limit the shape of the connecting rope 12.

[0211] In some embodiments, the elastic modulus of the connecting rope 12 is greater than the elastic modulus of the elastic rope 30. In this embodiment, since the elastic modulus of the connecting rope 12 is greater than the elastic modulus of the elastic rope 30, the force required for the connecting rope 12 to deform is greater than the force required for the elastic rope 30 to deform, and thus the tension required for the connecting rope 12 to be stretched is greater than the tension required for the elastic rope 30 to deform.

[0212] Among them, when the wearable device 1000 is in the detection state, the elastic modulus of the connecting rope 12 is greater than the elastic modulus of the elastic rope 30, which increases the restriction of the connecting rope 12 on the tensile deformation of the elastic rope 30, thereby further restricting the second end 2004 of the connecting belt 200 from moving away from the shell 20 along the extension direction of the connecting belt 200, which is beneficial to the stable wearing of the main body 100 and improves the accuracy of detection.

[0213] Among them, when the wearable device 1000 is in a non-detection state, the elastic modulus of the connecting rope 12 is greater than the elastic modulus of the elastic rope 30, so that when the elastic rope 30 is stretched and deformed, the maximum size of the stretching deformation of the elastic rope 30 will be limited by the length of the part of the connecting rope 12 located outside the shell 20, thereby limiting the stretching deformation range of the elastic rope 30, and thus making the wearable device 1000 comfortable to wear while having good structural strength.

[0214] Exemplarily, the connecting rope 12 may be an inelastic member. In the present embodiment, by setting the connecting rope 12 as an inelastic member, the elastic rope 30 can be better restricted from being stretched and deformed when the wearable device 1000 is in the detection state, so that the elastic connection of the elastic rope 30 fails, thereby further restricting the second end 2004 of the connecting belt 200 from moving away from the housing 20 along the extension direction of the connecting belt 200, thereby facilitating the stable wearing of the main body 100 and improving the accuracy of the detection. For example, the connecting rope 12 may be an inelastic ultra-thin soft belt. The connecting rope 12 being an inelastic member does not mean that the connecting rope 12 cannot be deformed at all, but means that the connecting rope 12 is difficult to be stretched and deformed when subjected to force, for example, the elastic modulus of the connecting rope 12 is greater than 1 GPa.

[0215] Exemplarily, the connecting rope 12 may be made of nylon material. In this embodiment, by setting the connecting rope 12 to be made of nylon material, the connecting rope 12 has a larger elastic modulus, so that the connecting rope 12 is not easily stretched and deformed by force, and then the connecting rope 12 better restricts the elastic rope 30 from being stretched and deformed when the wearable device 1000 is in the detection state, so that the elastic connection of the elastic rope 30 fails, thereby further restricting the second end 2004 of the connecting belt 200 from moving away from the housing 20 along the extension direction of the connecting belt 200, which is conducive to the stable wearing of the main body 100 and improves the accuracy of detection.

[0216] Please refer to Fig. 7A and Fig.7D , Fig.7D yes Fig. 7A The diagram is a schematic diagram showing a comparison of the widths of the connecting rope 12 and the elastic rope 30 in the wearable device 1000 in some embodiments.

[0217] In some embodiments, the width of the connecting rope 12 may be greater than the width of the elastic rope 30. In this embodiment, by setting the connecting rope 12 to have a wider width than the elastic rope 30, the connection between the second end 2004 of the connecting strap 200 and the housing 20 is more stable, and the connecting strap 200 can provide a better sense of support, which is conducive to improving the wearing feeling of the wearable device 1000.

[0218] Exemplarily, the wearable device 1000 may include two elastic cords 30, which are stacked and spaced apart in the thickness direction of the connecting belt 200. In this embodiment, the connecting belt 200 is elastically connected to the housing 20 through the two elastic cords 30, which improves the strength of the elastic connection between the connecting belt 200 and the housing 20, and can improve the stability of the connection between the connecting belt 200 and the housing 20.

[0219] The connecting rope 12 may be disposed between the two elastic ropes 30. In this embodiment, by disposing the connecting rope 12 between the two elastic ropes 30, the two elastic ropes 30 are symmetrically disposed compared to the connecting rope 12, thereby improving the stability of the elastic deformation of the elastic rope 30 when the connecting belt 200 moves compared to the housing 20. In addition, the two elastic ropes 30 can also limit the connecting rope 12, so as to prevent the portion of the elastic rope 30 located outside the housing 20 from deviating too much compared to the connecting belt 200 when it is longer.

[0220] In some implementations, the main body 100 may further include a driving circuit 50 and a processor 40. The driving circuit 50 is electrically connected to the driving member 13. The processor 40 is electrically connected to the driving circuit 50. The processor 40 is used to control the driving circuit 50 to drive the connecting rope 12 in response to the detection signal.

[0221] Exemplarily, the processor 40 responds to the detection signal, the wearable device 1000 enters the detection state from the non-detection state, and the processor 40 instructs the drive circuit 50 to control the drive member 13 to drive the connecting rope 12, so that the length of the portion of the connecting rope 12 outside the housing 20 is less than or equal to the length of the elastic rope 30. Alternatively, after the wearable device 1000 detects the target parameter, the processor 40 responds to the detection end signal, the wearable device 1000 enters the non-detection state from the detection state, and the processor 40 instructs the drive circuit 50 to control the drive member 13 to reversely drive the connecting rope 12, so that the length of the portion of the connecting rope 12 outside the housing 20 is greater than the length of the elastic rope 30.

[0222] When the wearable device 1000 is in a non-detection state, the connecting cord 12 has a length threshold, and the processor 40 is used to control the length of the portion of the connecting cord 12 outside the housing 20 to be less than the length threshold. By controlling the length of the portion of the connecting cord 12 outside the housing 20 to be less than the length threshold when the wearable device 1000 is in a non-detection state by the processor 40, it is possible to prevent the portion of the connecting cord 12 outside the housing 20 from being too long and causing too many wrinkles, thereby improving the wearing feeling of the wearable device 1000.

[0223] The wearable device 1000 may also have a control key, which may be used to adjust the length of the portion of the connecting rope 12 outside the housing 20 when the wearable device 1000 is in a non-detection state. In this embodiment, the wearable device 1000 may adjust the length of the portion of the connecting rope 12 outside the housing 20 through the control key, so that the user can flexibly adjust the length of the portion of the connecting rope 12 outside the housing 20 when the wearable device 1000 is in a non-detection state according to specific needs, thereby achieving customization and catering to the sensitivity of different users to the sense of wrinkles. The control key may be a physical button of the wearable device 1000 or a touch button of the interactive interface of the main body 100.

[0224] In addition, the control key can also be used to adjust the length of the portion of the connecting rope 12 located outside the shell 20 when the wearable device 1000 is in the detection state, thereby achieving stepless adjustment of the length of the portion of the connecting rope 12 located outside the shell 20, and further achieving stepless adjustment of the tightness.

[0225] Please refer to FIG. 8A to FIG. 8C , Fig. 8A yes Fig. 7A The structure diagram of the driving member 13 in the wearable device 1000 in some embodiments is shown; Figure 8B yes Fig. 8A The structural schematic diagram of the wearable device 1000 shown is in a detection state; Figure 8C yes Fig. 8A The structural diagram of the wearable device 1000 shown in FIG. 1 is in a non-detection state. The dotted line with an arrow in the figure indicates the movement direction of the connecting rope 12.

[0226] In some embodiments, the driving member 13 may include a motor 131, a first gear 132, a second gear 133, and a transmission shaft 134. The first gear 132 is sleeved on an output shaft 1311 of the motor 131. The second gear 133 is transmission-connected to the first gear 132. The first portion of the transmission shaft 134 is passed through the second gear 133, and the second portion of the transmission shaft 134 protrudes from the second gear 133. The first end 121 of the connecting rope 12 is wound around the second portion of the transmission shaft 134.

[0227] In this embodiment, the first gear 132 can be connected to the output shaft 1311 of the motor 131, and the motor 131 drives the first gear 132 to rotate through the output shaft 1311, and drives the second gear 133 to rotate through the first gear 132. The transmission shaft 134 can be connected to the second gear 133, and the second gear 133 can drive the transmission shaft 134 to rotate so as to wind up the first end 121 of the connecting rope 12, so that the length of the portion of the connecting rope 12 located outside the housing 20 is less than or equal to the length of the elastic rope 30, so that the elastic connection of the elastic rope 30 fails. The second gear 133 can also drive the transmission shaft 134 to rotate in the opposite direction so as to unfold the first end 121 of the connecting rope 12, so that the length of the portion of the connecting rope 12 located outside the housing 20 is greater than the length of the elastic rope 30, so that the elastic rope 30 recovers the elastic connection.

[0228] Exemplarily, the driving member 13 may further include a third gear 135, which is disposed between the first gear 132 and the second gear 133, and the third gear 135 is respectively meshed with the first gear 132 and the second gear 133. In this embodiment, the third gear 135 is provided to facilitate control of the speed ratio between the output shaft 1311 of the motor 131 and the transmission shaft 134, thereby facilitating a more stable transmission connection between the motor 131 and the transmission shaft 134, and improving the stability of the driving connection rope 12.

[0229] Exemplarily, the surface of the connecting belt 200 can be roughened to increase the surface roughness of the connecting belt 200, thereby avoiding slippage between the transmission shaft 134 and the connecting belt 200 when the connecting belt 200 is wound or unfolded, which is beneficial to improving the stability of the driving connecting rope 12.

[0230] See also Fig. 9 , Fig. 9 yes Fig. 7A Schematic diagram of the structure of the driving component 13 in the wearable device 1000 in other embodiments. Fig. 9 The wearable device 1000 of the illustrated embodiment may include FIG. 8A to FIG. 8C Most of the technical features of the wearable device 1000 of the illustrated embodiment are described below mainly in terms of the differences between the two, and most of the same contents between the two are not repeated here.

[0231] In some embodiments, the connecting rope 12 may be provided with a plurality of meshing holes 123, and the plurality of meshing holes 123 are arranged at intervals along the extension direction of the connecting rope 12. The second portion of the transmission shaft 134 may be provided with a plurality of meshing teeth 1341 in the circumferential direction, and the plurality of meshing teeth 1341 are arranged at intervals along the circumferential direction of the transmission shaft 134, and the meshing teeth 1341 are matched and connected with the meshing holes 123.

[0232] In this embodiment, the transmission shaft 134 can be connected to the meshing hole 123 on the connecting rope 12 through the meshing teeth 1341, so that when the first end 121 of the connecting rope 12 is wound onto the transmission shaft 134, the side wall of the meshing hole 123 and the outer peripheral side of the meshing teeth 1341 form a limit, which improves the stability of the first end 121 of the connecting rope 12 being wound onto the transmission shaft 134. In the process of winding the connecting rope 12, the transmission shaft 134 can clamp the meshing hole 123 on the connecting rope 12 through the meshing teeth 1341 to cooperate with the rotation of the transmission shaft 134 to wind up the connecting rope 12, thereby improving the force of winding up the connecting rope 12 and preventing the connecting rope 12 from slipping during the winding process, which is conducive to the stable operation of the driving member 13.

[0233] See also Fig.10 , Fig.10 yes Fig. 6A Schematic diagram of the structure of the driving component 13 in the wearable device 1000 in some other embodiments. Fig.10 The wearable device 1000 of the illustrated embodiment may include FIG. 8A to FIG. 8C Most of the technical features of the wearable device 1000 of the illustrated embodiment are described below mainly in terms of the differences between the two, and most of the same contents between the two are not repeated here.

[0234] In some embodiments, the driving member 13 may include a motor 131, and an output shaft 1311 of the motor 131 is connected to the first end 121 of the connecting rope 12, and is used to wind or unfold the connecting rope 12. In this embodiment, the output shaft 1311 of the motor 131 is directly connected to the first end 121 of the connecting rope 12, so that the motor 131 can directly wind or unfold the connecting rope 12, which simplifies the transmission structure, is conducive to improving the transmission efficiency, and realizes the miniaturization design of the driving member 13.

[0235] For example, Fig.10 The connecting rope 12 of the embodiment shown can be used Fig. 9 The design of the engagement hole 123 in the connecting rope 12 of the illustrated embodiment corresponds to: Fig.10 The output shaft 1311 of the motor 131 of the embodiment shown can be Fig. 9 The design of the meshing teeth 1341 in the transmission shaft 134 of the illustrated embodiment improves the stability of the output shaft 1311 of the motor 131 in winding or unfolding the connecting rope 12 .

[0236] See also Fig.11A , Fig.11A yes Fig. 7A Schematic diagram of the structure of the driving component 13 in the wearable device 1000 in some other embodiments.

[0237] In some embodiments, the driving member 13 in the wearable device 1000 may include a motor 131, a lead screw 136, and a sleeve 137. The motor 131 is transmission-connected to the lead screw 136. The sleeve 137 is sleeved on the lead screw 136 and transmission-connected to the lead screw 136. The sleeve 137 is fixedly connected to the first end 121 of the connecting rope 12. The motor 131 is used to drive the lead screw 136 to rotate, so that the sleeve 137 drives the first end 121 of the connecting rope 12 to move relative to the lead screw 136.

[0238] In this embodiment, the motor 131 drives the lead screw 136 to rotate, so that the sleeve 137 moves relative to the lead screw 136 along the extension direction of the lead screw 136, thereby driving the first end 121 of the connecting rope 12 to move relative to the lead screw 136, thereby changing the length of the portion of the connecting rope 12 located outside the housing 20. In this embodiment, the length of the portion of the connecting rope 12 located outside the housing 20 is changed by pulling the first end 121 of the connecting rope 12 by the sleeve 137, and the first end 121 of the connecting rope 12 does not need to be wound, which can reduce the wrinkles formed on the connecting rope 12 after multiple windings, and can avoid bending fatigue of the connecting rope 12 after multiple windings, thereby increasing the service life of the connecting rope 12.

[0239] Exemplarily, the lead screw 136 and the sleeve 137 can be threadedly connected. The outer peripheral side of the lead screw 136 is provided with an external thread, and the sleeve 137 has a threaded hole, and the external thread of the lead screw and the threaded hole of the sleeve 137 are matched and connected, so that the lead screw 136 and the sleeve 137 can rotate relative to each other and move relative to each other along the extension direction of the lead screw 136. Therefore, by limiting the rotation of the sleeve 137 and limiting the displacement of the lead screw 136, it can be achieved that when the motor 131 drives the lead screw to rotate, the sleeve 137 can move along the extension direction of the lead screw 136, thereby driving the first end 121 of the connecting rope 12 to move, and then changing the length of the portion of the connecting rope 12 located outside the housing 20.

[0240] Exemplarily, the driving member 13 may further include a plurality of balls (not shown in the figure). The balls are arranged between the inner side of the sleeve 137 and the outer side of the lead screw 136, and the balls are located in the guide groove between the sleeve 137 and the lead screw 136. The motor 131 drives the lead screw 136 to rotate, thereby driving the balls to roll, and the motion force generated by the rolling of the balls drives the sleeve 137 to move relative to the lead screw 136 along the extension direction of the lead screw 136. In this embodiment, since the rolling friction coefficient of the balls is low, the friction loss of the first end 121 of the connecting rope 12 driven by the driving member 13 is reduced, thereby saving energy and improving the working efficiency of the driving member 13.

[0241] The first end 121 of the connecting rope 12 can be directly fixed to the sleeve 137, for example, bonded to the outer peripheral side of the sleeve 137, embedded in the sleeve 137 and bonded to the sleeve 137. Alternatively, the first end 121 of the connecting rope 12 can be fixed to the sleeve 137 by a fixing bolt, which can be detachably connected to the sleeve 137 or non-detachably connected to the sleeve 137, and the first end 121 of the connecting rope 12 is fixedly connected to the fixing bolt.

[0242] Please refer to Fig. 11B and Fig. 11C , Fig. 11B yes Fig.11A The structural schematic diagram of the wearable device 1000 shown is in a detection state; Fig. 11C yes Fig.11A The structural schematic diagram of the wearable device 1000 shown in the figure is in a non-detection state. In the figure, the dashed straight line with an arrow represents the movement direction of the sleeve 137, and the dashed curved line with an arrow represents the rotation direction of the lead screw 136.

[0243] In some embodiments, when the wearable device 1000 is in the detection state, the motor 131 drives the screw 136 to rotate, thereby driving the sleeve 137 to drive the first end 121 of the connecting rope 12 to move toward the inside of the shell 20 relative to the screw 136, so that the length of the part of the connecting rope 12 located outside the shell 20 is less than or equal to the length of the elastic rope 30, thereby making the elastic connection of the elastic rope 30 invalid.

[0244] In this embodiment, when the wearable device 1000 is in non-detection state, the motor 131 drives the lead screw 136 to rotate in the reverse direction, thereby driving the sleeve 137 to drive the first end 121 of the connecting rope 12 to move toward the outside of the shell 20 relative to the lead screw 136, so that the length of the portion of the connecting rope 12 located outside the shell 20 is greater than the length of the elastic rope 30, thereby restoring the elastic connection of the elastic rope 30.
