A wristwatch, a control method, a control device, a wearable device, and a readable storage medium according to embodiments of the application are described below with reference to fig. 1 to 18.

As shown in fig. 1 to 9, an embodiment according to a first aspect of the present application provides a wristwatch 10. Watch 10 includes case 100, wristband assembly 110, wristband 132, gear 144, and motor 140.

As shown in fig. 5, in particular, one side of case 100 is connected to one end of wristband assembly 110. The ring gear 132 is rotatably disposed within the case 100. Part of wristband assembly 110 is wrapped around toothed ring 132 in a circumferential roping slot 1320. The motor 140 is disposed within the case 100, and a gear 144 is connected to the motor 140. The motor 140 can drive the ring gear 132 to rotate via the gear 144.

When gear 144 and toothed ring 132 are engaged, motor 140 drives gear 144 to rotate toothed ring 132 in a first direction, causing a portion of wristband assembly 110 to wrap more around toothed ring 132 as toothed ring 132 rotates, thereby completing the gathering of wristband assembly 110. Motor 140 drives gear 144 to rotate toothed ring 132 in a second direction, which unwinds a portion of wristband assembly 110 wrapped around a roping slot 1320 of toothed ring 132.

Further, when the gear 144 and the ring gear 132 are separated, the motor 140 is used to drive the watch 10 to vibrate.

Watch 10 according to an embodiment of the present application includes wristband assembly 110, wristband 132, gear 144, and motor 140. It will be appreciated that the ring gear is rotatably disposed within the case 100 and that the gear 144 is separate from or in engagement with the ring gear 132. When engaged, motor 140 drives gear 144 to rotate toothed ring 132, and a portion of wristband assembly 110 is wound around a roping slot 1320 of toothed ring 132. Further, when motor 140 drives gear 144 to rotate toothed ring 132 in the first direction, portions of wristband assembly 110 may be wound more around toothed ring 132 and thereby retracted. When motor 140 drives gear 144 to rotate toothed ring 132 in the second direction, wristband assembly 110 wrapped around toothed ring 132 may be stretched. In this way, gear 144 is driven by motor 140 to rotate toothed ring 132, thereby adjusting the length of wear of wristband assembly 110. In the whole adjusting process, the user can automatically adjust the wearing tightness of the watch 10 by only starting the motor 140 with one hand, and the user does not need to operate with two hands, so that the convenience of adjusting the length of the watchband component 110 is greatly improved. In addition, the motor 140 drives the gear 144 to drive the toothed ring 132 to rotate, so that the length of the watchband component 110 wound on the toothed ring 132 is changed, and the adjustment mode is self-adaptive stepless adjustment, so that the wrist watch is more beneficial to adapting to wrists with different thicknesses, and the length of the watchband component 110 is more finely adjusted by a user, so that the wearing comfort of the watch 10 is improved. In addition, because the wristband assembly 110 may be steplessly adjustable in length, it may also facilitate providing conditions for the functions of the wristwatch 10, such as blood pressure detection, and provide a more comfortable and intelligent wearing experience for the user.

It will be appreciated that the first direction and the second direction are opposite. For example, the first direction is counter-clockwise, and the second direction is clockwise. Or the first direction is clockwise and the second direction is counter-clockwise.

Specifically, by providing the case 100, it is convenient to accommodate the toothed ring 132, the motor 140, and the like. By providing wristband assembly 110 with one end of wristband assembly 110 connected to one side of case 100, wristwatch 10 is facilitated to be worn. The toothed ring 132 is rotatably disposed in the case 100, and a portion of the watchband component 110 is wound around the rope winding slot 1320 of the toothed ring 132, so that when the toothed ring 132 rotates, the watchband component 110 is driven to be folded or unfolded, and the stepless adjustment of the length of the watchband component 110 is realized. The placement of the strap assembly 110 around the slot 1320 may reduce the likelihood of the strap assembly falling out. By providing the motor 140, the motor 140 can drive the toothed ring 132 to rotate in a first direction or in a second opposite direction, and thus, manual operation by a user is not required, thereby achieving the purpose of adjusting the tightness of the wristwatch 10 with one hand. When motor 140 drives toothed ring 132 in a first direction, wristband assembly 110 may be wound around toothed ring 132 more and retracted, allowing wristwatch 10 to be worn more tightly. When motor 140 drives toothed ring 132 in a reverse direction, i.e., in a second direction, wristband assembly 110 may be extended to allow wristwatch 10 to be more loosely worn.

As shown in fig. 8, when the gear 144 is separated from the ring gear 132, the motor 140 may drive the watch 10 to vibrate. That is, the motor 140 can drive the toothed ring 132 to rotate through the gear 144 to adjust the tightness of the watch 10, and vibrate to realize the functions of reminding and warning the watch 10, so that the watch has dual purposes, is beneficial to reducing the number of components, saving the space and the cost, and simplifying the structure.

As shown in fig. 4, gear 144 is driven by motor 140, and gear 144 engages with toothed ring 132 to drive toothed ring 132 in a forward or reverse direction, thereby enabling wristband assembly 110 to be drawn in or extended.

In the above embodiment, the wristwatch 10 further includes a first spacing structure and a first reset assembly 160. The first limiting structure is movably disposed in the case 100. The first limiting structure is used for limiting the rotation direction of the toothed ring 132. When the watchband is adjusted to a proper length, the rotation direction of the toothed ring 132 is limited by the first limiting structure, so that the toothed ring 132 can only rotate along one direction. When the wristwatch 10 needs to be tightened to fold the watchband component 110, the motor 140 drives the gear 144 to drive the toothed ring 132 to rotate along the first direction, and the toothed ring 132 cannot rotate reversely, that is, cannot rotate along the second direction, under the limitation of the first limiting structure, so that after the motor 140 stops driving, the length of the watchband component 110 can be fixed. The first reset assembly 160 is disposed within the case 100. The first reset component 160 is used for releasing or restoring the rotation direction limitation of the first limiting structure to the toothed ring 132. When the watch 10 needs to be loosened, the watchband component 110 is unfolded, the first reset component 160 releases the limit of the first limit structure to the rotation direction of the toothed ring 132, so that the toothed ring 132 can rotate along the first direction or the second direction, and at the moment, the motor 140 drives the toothed ring 132 to rotate along the second direction, so that the watchband component 110 is unfolded, and the length of the watchband component 110 is loosened. When the watchband assembly 110 needs to be folded again, the first reset assembly 160 is used to restore the limit of the first limit structure to the toothed ring 132, so that the toothed ring 132 can only rotate along the first direction.

Further, as shown in fig. 6, the first reset assembly 160 includes a magnetic body 162 and a first coil 164. The magnetic body 162 is disposed on the first limiting structure. The first coil 164 is provided on the inner wall of the case 100. The first coil 164 can generate magnetic force when energized, and thus can attract the magnetic body 162 when energized. It will be appreciated that the magnetic body 162 is disposed on the first limiting structure, and the first coil 164 is disposed on the inner wall of the case 100, and the first coil 164 is energized to generate magnetic force to attract the magnetic body 162, so that the magnetic body 162 can be moved to drive the first limiting structure to move, so that the first limiting structure is separated from the toothed ring 132, and the limitation of the first limiting structure on the rotation direction of the toothed ring 132 is released, so that the toothed ring 132 can rotate in the first direction or rotate in the second direction, and the watchband assembly 110 can be folded or unfolded along with the rotation of the toothed ring 132. After the power is off, the first coil 164 loses the magnetic force, so that the magnetic body 162 can be restored to the original position, and accordingly, the first limiting structure can also be restored to the original position, so that the limitation on the movement direction of the toothed ring 132 is restored, that is, the toothed ring 132 can only rotate along the first direction, and the watchband assembly 110 can only be folded but not unfolded. By the arrangement of the first limiting structure and the first reset component 160, the watchband component 110 can be locked at any length, thereby further ensuring stepless adjustment of the length of the watchband component 110.

Further, the first limit structure includes a detent 152. The magnetic body 162 is disposed on the first limiting structure. The pawls 152 cooperate with the toothed ring 132 to limit the rotational direction of the toothed ring 132. The first coil 164 generates a magnetic force when energized, attracts the magnetic body 162, and separates the driving pawl 152 from the ring gear 132. It will be appreciated that pawl 152 is movably disposed within case 100, and when pawl 152 engages ring gear 132, the rotational direction of ring gear 132 is limited such that ring gear 132 cannot rotate in the second direction, thereby allowing wristband assembly 110 to be folded and unfolded. Limiting the rotational direction of toothed ring 132 by pawl 152 limits the reverse deployment of wristband assembly 110, thereby securing the wristband length. First coil 164 is provided on the inner wall of case 100 and attracts magnetic body 162 of pawl 152 when energized, thereby lifting pawl 152 away from toothed ring 132, and releasing the restriction of pawl 152 on the rotational direction of toothed ring 132, so that band assembly 110 can be folded or unfolded.

Still further, the first spacing structure also includes a torsion spring 166. A torsion spring 166 is provided on the pawl 152. The torsion spring 166 drives the pawl 152 to return by its elastic force to engage the toothed ring 132. Specifically, when the first coil 164 is energized, the first coil 164 generates a magnetic force that attracts the magnetic body 162 on the pawl 152, thereby lifting the pawl 152 and separating the ring gear 132. When the first coil 164 is de-energized, the magnetic force on the first coil 164 is removed and the torsion spring 166 on the pawl 152 returns the pawl 152 back to engage the ring gear 132 by its elastic force, thereby again limiting the rotational direction of the ring gear 132.

As shown in fig. 3, in some embodiments, the watch 10 further includes a stand 170. The bracket 170 is provided in the case 100, and the bracket 170 is in a fixed state with the first case 102, and the pawl 152 is fitted between the first case 102 and the ring gear 132. The pawl 152 and the ring gear 132 are relatively movable upon rotation, and the pawl 152 is also movable relative to the first housing 102. The watch case 100 includes a first case 102 and a second case 104, wherein a bracket 170 is fixedly coupled to the second case 104. The bracket 170 not only supports the pawl 152, but also can fix and protect electronic components such as the screen 190. Pawl 152 is movably disposed on bracket 170 to facilitate disengagement and engagement of pawl 152 with toothed ring 132.

In some embodiments, the watch 10 also includes a second reset assembly 180. The second reset assembly 180 is used to disengage or mesh the drive gear 144 from the ring gear 132 to facilitate the motor 140's switching between the two functions of driving the ring gear 132 and vibrating.

Specifically, in some embodiments, the second reset assembly 180 is coupled to the motor 140. The second reset assembly 180 is driven by the drive motor 140 to disengage or engage the gear 144 with the ring gear 132. In other embodiments, the second reset assembly 180 is coupled to the gear 144. The second reset assembly 180 directly drives the gear 144 out of engagement or engagement with the ring gear 132.

It will be appreciated that by providing second reset assembly 180, drive gear 144 engages toothed ring 132 when it is desired to adjust the length of wristband assembly 110, thereby driving toothed ring 132 in a forward or reverse direction, i.e., driving toothed ring 132 in a first or second direction, to retract or extend wristband assembly 110. After adjusting wristband assembly 110 to a proper length, second reset assembly 180 drives gear 144 to disengage from toothed ring 132, stopping driving toothed ring 132 to rotate, making the length of wristband assembly 110 fixed, and at the same time, if motor 140 vibrates, the state of toothed ring 132 is not affected due to the separation of gear 144 and toothed ring 132.

In some embodiments, the second reset assembly 180 includes a spring 182 and a second coil 184. One end of the elastic member 182 is connected to the motor 140. The spring 182 is used to support and drive the motor 140 to maintain a spacing between the gear 144 and the ring gear 132 to avoid meshing. The second coil 184 is disposed on the bracket 170. The second coil 184 generates a suction force when energized, and attracts the motor 140 or the gear 144, thereby compressing the elastic member 182, and reducing the space between the gear 144 and the ring gear 132 until the gear 144 and the ring gear 132 are engaged with each other, so that the gear 144 is driven to rotate when the motor 140 is started. When the second coil 184 is de-energized, the suction force is lost, and the gear 144 and the ring gear 132 are separated under the elastic force of the elastic member 182, so that the motor 140 can no longer drive the ring gear 132 to rotate through the gear 144.

It will be appreciated that the spring 182 may be coupled to the motor 140 or may be biased against it. By providing one end of the elastic member 182 connected to or abutting against the motor 140, the elastic member 182 can be made to separate the gear 144 from the ring gear 132 in a natural state. When the second coil 184 is energized, the spring 182 will be compressed, causing the motor 140 to move downward and the gear 144 to engage the ring gear 132.

As shown in fig. 2, in any of the above embodiments, wristband assembly 110 includes a first wristband 112, a second wristband 114, and a cord 116. One side of the case 100 is connected to one end of a first wristband 112, and the other side of the case 100 is connected to one end of a second wristband 114. The other end of the first band 112 abuts the other end of the second band 114. One end of the cord 116 is fixedly attached to the case 100, the other end of the cord 116 is connected to the toothed ring 132, and the cord 116 is also connected to the first band 112 and the second band 114, respectively.

Specifically, one end of the rope 116 is connected to the toothed ring 132, and the other end is fixed to the case 100, and the motor 140 drives the toothed ring 132 to rotate in a forward and reverse direction, so that the rope 116 is correspondingly folded or unfolded, and the overlapping length of the first watchband 112 and the second watchband 114 is shortened or lengthened, thereby folding or unfolding the watchband assembly 110. The cord 116 is connected to the first band 112 and the second band 114, respectively, so that the wristwatch 10 can be worn on the wrist, and the tension of the wristwatch 10 can be adjusted by folding or unfolding the cord 116 since the other end of the second band 114 is abutted against the other end of the first band 112.

Further, a first rope passing structure 118 is provided on the first watchband 112, and the first rope passing structure 118 is provided along the length direction of the first watchband 112. The first roping arrangement 118 is used for the passage of the rope 116. The second strap 114 is provided with a second cord structure 120, and the second cord structure 120 is disposed along a length of the second strap 114. The second roping arrangement 120 is also used for the passage of the rope 116. First strand structure 118 is a limiting portion of first band 112 for limiting the position of strand 116 on first band 112. By providing the first string passing structure 118, the string 116 can be attached to the first watchband 112 all the time, so as to drive the first watchband 112 to move along the length direction thereof. The second strand structure 120 is a stop portion of the second wristband 114 for limiting the position of the strand 116 on the second wristband 114. By providing the second string passing structure 120, the string 116 can always attach to the second watchband 114, so as to drive the second watchband 114 to move along the length direction thereof.

In some embodiments, a third rope passing structure is provided on one side of the case 100, one end of the rope 116 is connected to the other side of the case 100, the rope 116 passes through the first rope passing structure 118, the second rope passing structure 120 and the third rope passing structure, respectively, the other end of the rope 116 is connected to the toothed ring 132, and the rope is wound in the rope winding groove 1320. One end of the rope 116 is fixedly arranged on the watchcase 100, the rope structure 118, the second rope structure 120 and the third rope structure are movably penetrated, the other end of the rope is connected with the toothed ring 132, so that the rope 116 can form two parallel sections on the watchband component 110, when the toothed ring 132 rotates, the rope 116 can be correspondingly folded or unfolded more uniformly, and the stress uniformity and the movement stability of the watchband component 110 are improved.

In some embodiments, the cord 116 is an elastomer. It will be appreciated that when wristwatch 10 is worn, the band assembly 110 is folded or unfolded by tightening or loosening of the cord 116, thereby adjusting the tightness of the wear. When the wristwatch 10 is tightened, the ring gear 132 rotates to cause more of the cord 116 to be wound into the cord winding slot 1320, and tension is applied to the cord 116 to cause the cord 116 to be stretched and tension to build up. When the wristwatch 10 is loosened, the motor 140 is stopped, the limit of the first limit structure is released, the toothed ring 132 can rotate reversely, at the moment, under the action of the tension on the rope 116, the rope 116 is automatically contracted, the toothed ring 132 is pulled to rotate reversely, the rope 116 wound on the toothed ring 132 is unfolded, and correspondingly, the watchband component 110 is unfolded, so that the unfolding is assisted by the tension accumulated on the rope 116 during the folding, the energy consumption of the motor 140 is reduced, and the electric energy is saved.

In other embodiments, an elastomer is connected between one end of the cord 116 and the case 100. The ring gear 132 can be driven in an auxiliary manner by the tension accumulated by the elastic body during folding and unfolding, so that the energy consumption of the motor 140 is reduced and the electric energy is saved.

The first housing 102 and the second housing 104 are detachably connected, which is advantageous in facilitating assembly of the motor 140, the ring gear 132, and the like.

As shown in fig. 7, in some embodiments, the watch 10 also includes a pressure sensor 210. A pressure sensor 210 is provided on the case 100, the pressure sensor 210 being adapted to detect the pressure on the wristwatch 10 in order to determine the tightness of the wristwatch 10 or to detect whether the wrist is pressed against the case 100. As shown in fig. 9, when the smart watch 10 is integrated with the bio-signal sensor 230, detection of bio-signals can also be performed. For example, the wristwatch 10 is integrated with the blood pressure sensor 340, so that the function of blood pressure detection can be realized, that is, the blood pressure sensor 340 can be used for blood pressure detection.

In other embodiments, the watch 10 further includes a rotary encoder. A rotary encoder is provided on the toothed ring 132 for detecting the winding length of the rope 116 on the toothed ring 132. The length of wristband assembly 110 may be determined accordingly.

And a plurality of different lengths can be memorized, so that the user can conveniently and quickly switch to adapt to different scenes.

As shown in fig. 13, an embodiment according to a second aspect of the present application provides a control method for controlling the wristwatch according to any one of the embodiments of the first aspect. The control method comprises the following steps:

step S100: acquiring user input;

step S102: according to the user input, the motor is controlled to drive the toothed ring to rotate, and the watchband component is folded or unfolded.

According to the control method provided by the embodiment of the second aspect of the application, when the wearing tightness of the watch needs to be adjusted, the toothed ring is driven to rotate by the control motor, and the watchband component is folded or unfolded. The watchband component is folded, and the watch is worn more tightly. The watch band assembly is unfolded and the watch is more loosely worn. In the whole adjusting process, a user can automatically adjust the tightness of wearing the watch by starting the motor by only one hand, two hands are not needed to operate, and the convenience of adjusting the length of the watchband component is greatly improved. In addition, because the motor drives the toothed ring to rotate, the length of the watchband component wound on the toothed ring is changed, so that the adjusting mode is self-adaptive stepless adjustment, the wrist watch is more beneficial to adapting to wrists with different thicknesses, and the length of the watchband component is more finely adjusted by a user, so that the wearing comfort of the watch is improved. In addition, because the watchband component can be stepless in length adjustment, the watch is convenient to provide conditions for the functions of blood pressure detection and the like, and more comfortable and intelligent wearing experience is brought to a user.

As shown in fig. 14, another embodiment of the second aspect of the present application provides a control method, including:

step S200: acquiring user input;

step S202: if the user input is to draw in the watchband component, controlling the first limiting structure to limit the movement direction of the toothed ring and controlling the gear to be meshed with the toothed ring;

step S204: controlling a motor to drive a gear to drive a toothed ring to rotate along a first direction, so that the watchband component is folded;

step S206: judging whether the pressure sensed by the pressure sensor is greater than or equal to a first pressure threshold value, if not, executing step S204;

step S208: if yes, controlling the motor to stop running and controlling the gear to be separated from the toothed ring;

step S210: if the user input is that the watchband component is unfolded, controlling the first limiting structure to release the limitation on the movement direction of the toothed ring, and controlling the gear to be meshed with the toothed ring;

step S212: controlling a motor to drive the gear to drive the toothed ring to rotate along a second direction, so that the watchband component is unfolded;

step S214: judging whether the pressure sensed by the pressure sensor is smaller than a second pressure threshold value, if not, executing step S212;

step S216: if so, controlling the motor to stop running, controlling the first limiting structure to restore the limitation on the movement direction of the toothed ring, and controlling the gear to be separated from the toothed ring;

Step S220: if the user input is a biological signal, controlling the first limiting structure to limit the movement direction of the toothed ring and controlling the gear to be meshed with the toothed ring;

step S222: controlling a motor to drive a gear to drive a toothed ring to rotate along a first direction, so that the watchband component is folded;

step S224: judging whether the pressure sensed by the pressure sensor is greater than a third pressure threshold, if not, executing step S222;

step S226: if so, controlling the motor to stop running, controlling the first limiting structure to restore the limitation on the movement direction of the toothed ring, and controlling the gear to be separated from the toothed ring;

step S228: the biological signal sensor is controlled to detect the biological signal.

Wherein the first pressure threshold is greater than the second pressure threshold and less than the third pressure threshold.

In this embodiment, when the user inputs a folding command, the first limiting structure is controlled to limit the movement direction of the toothed ring, and the gear is controlled to engage with the toothed ring, so that the toothed ring can only rotate in the first direction, that is, the watchband component can only be folded but cannot be unfolded. Then the motor is controlled to drive the gear to drive the toothed ring to rotate along the first direction, so that the watchband component is folded, and the watch is worn more and more tightly. And then judging whether the tightness of the watch is proper or not by judging whether the pressure sensed by the pressure sensor is greater than or equal to a first pressure threshold value. If the pressure sensed by the pressure sensor is smaller than the first pressure threshold value, indicating that the wearing is insufficient, the motor is controlled to continuously operate, and the watchband component is continuously folded. If the pressure sensed by the pressure sensor is greater than or equal to the first pressure threshold, the wristwatch is tightly worn, the motor can be controlled to stop running, the gear is controlled to be separated from the toothed ring, the motor can not fold the watchband component at the moment, the first limiting structure limits the rotating direction of the toothed ring, so that the toothed ring can not reversely rotate along the second direction, the length of the watchband component is locked, and accordingly the tightness degree of the wristwatch is fixed.

If the user input is to expand the watchband component, the first limiting structure is controlled to release the limitation on the movement direction of the toothed ring, so that the toothed ring can rotate in the first direction and also can rotate in the second direction. Simultaneously, the gear is controlled to be meshed with the toothed ring, so that the gear can drive the toothed ring. Then the motor is controlled to drive the gear to rotate the toothed ring in a second direction, so that the watchband component is unfolded, and the watch is worn more and more loosely. And then judging whether the watchband component is unfolded to a proper position by judging whether the pressure sensed by the pressure sensor is smaller than a second pressure threshold value so as to be convenient for relaxing the wrist or taking off the watch. If the pressure sensed by the pressure sensor is greater than or equal to the second pressure threshold, the wristwatch is still worn tightly, the motor is controlled to continuously operate, and the watchband component is continuously unfolded. If the pressure sensed by the pressure sensor is less than the second pressure threshold, the wristwatch is loose enough to relax the wrist or can be taken off, at the moment, the motor is controlled to stop running, the first limiting structure is controlled to restore the limitation on the movement direction of the toothed ring, and the gear is controlled to be separated from the toothed ring, so that the length of the watchband component is locked. The second pressure threshold is smaller than the first pressure threshold, so that the wrist can be smoothly taken off or relaxed due to enough looseness of the watch.

If the user inputs a biological signal, the first limiting structure is controlled to limit the movement direction of the toothed ring, and the gear is controlled to be meshed with the toothed ring, so that the toothed ring can only rotate along the first direction, namely the watchband component can only be folded but not unfolded. Then the motor is controlled to drive the gear to drive the toothed ring to rotate along the first direction, so that the watchband component is folded. And judging whether the watchband component is folded to a proper position or not by judging whether the pressure sensed by the pressure sensor is greater than a third pressure threshold value. If the pressure sensed by the pressure sensor is smaller than or equal to the third pressure threshold, the wristwatch is loose and is not clung to a human body, so that accurate biological signal measurement is not facilitated, and the motor is controlled to continuously run. If the pressure sensed by the pressure sensor is greater than the third pressure threshold, the wristwatch is tightly attached to a human body, so that the motor can be controlled to stop running, the first limiting structure is controlled to restore the limitation on the movement direction of the toothed ring, and the length of the watchband component is locked. And the gear is controlled to be separated from the toothed ring, so that the watchband component is prevented from being folded again due to misoperation. After the length of the watchband component is adjusted in place, biological signals are detected by controlling the biological signal sensor so as to know the health condition of a human body. The biological signal sensor can be heart rate sensor, electrocardiogram sensor, blood pressure sensor, etc., and can monitor the motion, sleep, health, etc. of the user. The third pressure threshold is larger than the first pressure threshold, so that the watch can be tightly attached to a human body, and accuracy and reliability of biological signal detection are improved.

In other embodiments, the tightness of the watch is not limited to being determined by a pressure sensor. Instead of the pressure sensor, a rotary encoder may be provided on the wristwatch. I.e. by measuring the length of the wristband assembly by means of a rotary encoder or the length of the wristband assembly wound around the toothed ring. It will be appreciated that the rotary encoder may measure rotational speed, and in combination with the circumference, radius, etc. of the toothed ring, calculate the length of the wristband assembly wrapped around the toothed ring, or calculate the length of the wristband assembly not yet wrapped around the toothed ring. In particular, for example, the circumference of the wristband assembly may be measured. When the watchband component is folded, a first length threshold value is adopted for measurement; the circumference is larger than a first length threshold value, which indicates that the watch is loose and needs to be folded continuously; the circumference is less than or equal to the first length threshold, which indicates that the watch is tighter and can stop folding. When the watchband component is unfolded, the second length threshold value is adopted for measurement; the circumference is smaller than or equal to a second length threshold, which indicates that the watch is tighter and can be unfolded continuously; the circumference being greater than the second length threshold, indicating that the watch is loose, the deployment may be stopped. When the biological signal is measured, the third length threshold is adopted for measurement, and the judgment mode is similar to that when the biological signal is folded, and is not repeated here. It is understood that the first length threshold is less than the second length threshold and greater than the third length threshold.

As shown in fig. 15, a control method according to still another embodiment of the second aspect of the present application is provided, including:

step S300: acquiring user input;

step S302: if the user input is to draw in the watchband component, the first coil is controlled to be powered off, so that the pawl is meshed with the toothed ring, and the movement direction of the toothed ring is limited;

step S304: controlling the second coil to be electrified so that the second coil and the motor are attracted to enable the gear to be meshed with the toothed ring, controlling the motor to drive the gear to drive the toothed ring to rotate along the first direction, and enabling the watchband component to be folded;

step S306: judging whether the pressure sensed by the pressure sensor is greater than or equal to a first pressure threshold value, if not, executing step S304;

step S308: if yes, controlling the motor to stop running and controlling the gear to be separated from the toothed ring;

step S320: if the user input is that the watchband component is unfolded, the first coil is controlled to be electrified, so that the pawl is separated from the toothed ring, and the limitation on the movement direction of the toothed ring is removed;

step S322: controlling the second coil to be electrified so as to enable the second coil to attract the motor, enabling the gear to be meshed with the toothed ring, controlling the motor to drive the gear to drive the toothed ring to rotate along the second direction, and enabling the watchband component to be unfolded;

step S324: judging whether the pressure sensed by the pressure sensor is smaller than a second pressure threshold, if not, executing step S322;

Step S326: if so, controlling the motor to stop running, controlling the pawl to be combined with the toothed ring, recovering the limitation on the movement direction of the toothed ring, and controlling the gear to be separated from the toothed ring;

step S330: if the user input is a biological signal, the first coil is controlled to be powered off, so that the pawl is meshed with the toothed ring, and the movement direction of the toothed ring is limited;

step S332: controlling the second coil to be electrified so as to enable the second coil to attract the motor, enabling the gear to be meshed with the toothed ring, controlling the motor to drive the gear to drive the toothed ring to rotate along the first direction, and enabling the watchband component to be unfolded;

step S334: judging whether the pressure sensed by the pressure sensor is greater than a third pressure threshold, if not, executing step S332;

step S336: if so, controlling the motor to stop running, controlling the pawl to restore to limit the movement direction of the toothed ring, and controlling the gear to be separated from the toothed ring;

step S338: the biological signal sensor is controlled to detect the biological signal.

In the above embodiment, the first coil is de-energized by controlling the first coil so that the first coil loses the magnetic force. The magnetic body on the pawl is no longer attracted by the first coil. Under the action of the torsion spring, the pawl is meshed with the toothed ring again, so that the limit on the rotation direction of the toothed ring is realized, the toothed ring can only rotate along the first direction, the watchband component can only be folded and can not be unfolded, the length of the watchband component is conveniently locked, and the purpose of tightening the watch is realized. The second coil is electrified, so that the second coil can generate magnetic force to attract the motor, the elastic piece is compressed, and the distance between the gear and the toothed ring is shortened, so that the gear can be meshed with the toothed ring and drive the toothed ring to rotate. After the motor is started, the gear can be driven to drive the toothed ring. Similarly, the first coil is connected and disconnected, and then the first coil generates magnetic force to attract the magnetic body, so that the pawl is separated from the toothed ring, the restriction of the rotation direction of the toothed ring is relieved, the toothed ring can rotate along the first direction and also can rotate along the second direction, and the watchband component can be unfolded. After the unfolding or folding is finished, the second coil can lose magnetic force as long as the second coil is powered off, and the motor drives the gear to be separated from the toothed ring under the elastic action of the elastic piece, so that the toothed ring loses rotating power and is stopped, and the length of the watchband component is locked. At the same time, the motor can realize its vibrating function without affecting the state of the toothed ring. In the process, the user only needs to control the power-on states of the first coil and the second coil, so that the operation of the user is simplified, and the user can complete the folding and unfolding of the watchband component by adopting one-hand operation.

(3) The function of the check pawl 152 is to keep the toothed ring 132 from reversing after the gear 144 is disengaged from the toothed ring 132 by the motor 140 when the wristband assembly 110 is adjusted to a suitable length, thereby keeping the cord 116 in a tightened state; when it is desired to release wristband assembly 110, check pawl 152 is reset by energizing first coil 164. (4) The elastic member 182 and the second coil 184 of the motor 140 are used for lifting the motor 140 after the watchband assembly 110 is adjusted, so that the gear 144 is separated from the gear ring 132, and the motor 140 is used. (5) The torsion spring 166 on the check pawl 152, the first coil 164, acts to lift the check pawl 152 away from the toothed ring 132 when it is desired to release the wristband assembly 110.

The working principle of the transmission group is shown in fig. 6: (1) When a user desires to tighten wristband assembly 110, first coil 164 is de-energized and second coil 184 is energized, tightening spring 182, moving motor 140 downward, causing gear 144 to engage toothed ring 132. The motor 140 rotates the toothed ring 132 forward, which drives the cord 116 to tighten the first band 112 and the second band 114. When tightened to the proper length, wristband assembly 110 is secured in length. The second coil 184 is de-energized and the motor 140 is lifted by the spring 182 attached to or abutting the motor 140, at which time the check pawl 152 ensures that the ring gear 132 cannot reverse. (2) When the user needs to remove the watch 10 or to loosen the wristband assembly 110, the first coil 164 is energized, lifting the check pawl 152, disengaging the pawl 152 from the toothed ring 132. The second coil 184 is energized to compress the elastic member 182, and the motor 140 moves downward to drive the gear 144 to engage the ring gear 132. The motor 140 rotates the toothed ring 132 in reverse, which drives the cord 116 to unwind the first band 112 and the second band 114. When released to the proper length, the first coil 164 is de-energized, lowering the check pawl 152 via the torsion spring 166. The second coil 184 is de-energized, the motor 140 is lifted by the spring 182, and the gear 144 and the ring gear 132 are separated.

The function of the various positions of the rope 116 is shown in fig. 8: (1) One end of the rope 116 passes through a third rope passing structure on the first casing 102, is connected with the first casing 102, and is matched and limited with the first casing 102. The third rope passing structure may be a through hole. The other end of the rope 116 is wound in the groove of the toothed ring 132, and the motor 140 drives the toothed ring 132 to rotate positively and negatively, so that the rope 116 is correspondingly tightened or loosened. (2) First and second cord structures 118, 120 of wristband assembly 110 allow cord 116 to always fit the wristband. (3) The check pawl 152 allows the ring gear 132 to keep the cord 116 from loosening after the motor 140 is disengaged.

A schematic layout of the sensor 340 is shown in fig. 9: (1) The bio-signal sensor 230, such as a heart rate sensor 340, an ECG (electrocardiogram) sensor 340, etc., can monitor the movement, sleep, health, etc., of the user in real time. (2) The pressure sensor 210 is used to detect whether the wrist is pressed down against the housing, and when the smart watch 10 integrates the function of blood pressure detection, the blood pressure sensor 340 can be used for blood pressure detection.

The flow chart of the smart watch automatic tightening watchband is shown in figure 16,

step S400: the first coil is powered off, the second coil is powered on, and the motor moves downwards to enable the gear to engage with the toothed ring;

Step S402: the motor drives the toothed ring to rotate positively;

step S404: the toothed ring drives the rope to tighten the watchband component;

step S406: judging whether the watchband component is smaller than or equal to a first length threshold value, if not, executing step S404;

step S408: if the second coil is powered off, the motor is lifted, and the pawl ensures that the toothed ring cannot rotate reversely.

After the watchband is tightened, the user can select and memorize the position of the watchband through the watch interactive interface, and the watchband is tightened next time. The system can also memorize multiple states, is convenient for a user to quickly switch so as to adapt to different scenes: sports, sleep, health, etc. scenarios.

The flowchart of removing the wristwatch or loosening the wristband is shown in fig. 17, and the user can quickly remove the wristwatch by loosening the wristband.

Step S500: the first coil is electrified to lift the check pawl to separate the pawl from the toothed ring, the second coil is electrified to move down the motor to drive the gear to engage with the toothed ring;

step S502: the motor drives the toothed ring to rotate reversely;

step S504: the toothed ring drives the rope to loosen the watchband component;

step S506: judging whether the watchband component is larger than a second length threshold value, if not, executing step S504;

step S508: if the first coil is powered off, the non-return pawl is put down through the torsion spring, and the toothed ring is limited to rotate reversely;

Step S510: the second coil is powered off, the motor is lifted by the elastic piece, and the gear and the toothed ring are separated.

When the wristwatch integrates the function of blood pressure detection, the pressure sensor can be used to identify whether the wrist is pressed against the second housing, the workflow diagram is shown in fig. 18:

step S600: the first coil is powered off, the second coil is powered on, and the motor moves downwards to enable the gear to engage with the toothed ring;

step S602: the motor drives the toothed ring to rotate positively;

step S604: the toothed ring drives the rope to tighten the watchband component;

step S606: judging whether the pressure sensed by the pressure sensor is greater than a third pressure threshold, if not, executing step S604;

step S608: if yes, the second coil is powered off, the motor is lifted, and the pawl ensures that the toothed ring cannot rotate reversely;

step S610: the sensor for measuring blood pressure works;

step S612: and (5) after the measurement is finished, restoring the watchband component length set by the user.
