Further, the binding band 21 may include a band body 211, and the band body 211 has an attaching surface 211a and an outer surface 211c opposite to the attaching surface 211 a. After the electronic device 10 is worn to the wrist of the user by the strap assembly 20, at least a portion of the engagement surface 211a faces the skin of the user and engages the body of the user. For example, without an intermediate garment, at least a portion of the attachment surface 211a is attached to the skin of the user. In the case of an intermediate garment, the engaging surface 211a may engage the garment. It is understood that the bonding surface 211a may be planar or curved.

Further, referring to fig. 4, taking the strap 21 with the function module 22 mounted thereon as an example, the strap 21 may further include a guide rail 213 disposed along the length extension direction of the belt body 211, and the function module 22 is slidably engaged with the guide rail 213 and can move along the length extension direction of the belt body 211 to adjust the position of the belt body 211. In the present embodiment, the lengthwise extending direction of the belt body 211 can be simply understood as an extending direction of the lengthwise dimension of the belt body 211 in a substantially flattened state. It is to be understood that the lengthwise extending direction of the belt body 211 is visually perceived even in a state where the belt body 211 is not flattened.

Referring to fig. 3, the functional module 22 is substantially rectangular block-shaped, and includes a body 220 and a driving mechanism 230, the body 220 is used for being mounted to the strap 21 of the wearable device 100, and the body 220 includes a functional device (not shown) for being communicatively connected with an external device or the electronic device 10 of the wearable device 100. The functional device may include one or more of a heart rate sensor, a blood pressure sensor, a camera, a fingerprint sensor, and the like. The heart rate sensor can be used for detecting the heart rate of a user, the blood pressure sensor can be used for detecting the blood pressure of the user, the camera can be used for shooting images or recording videos, and the fingerprint sensor can be used for verifying the identity of the user and used in payment and other use scenes. The external device may be, but is not limited to, a mobile phone, a tablet computer, a notebook computer, and the like. The driving mechanism 230 is connected to the body 220 and is used to drive the functional module 22 to move along the strap 21.

Specifically, the body 220 is substantially n-shaped, and includes a main body portion 221 and a fitting portion 223 connected to the main body portion 221, the main body portion 221 including the functional devices described above. Referring to fig. 4, the engaging portion 223 is slidably engaged with the rail 213, and the driving mechanism 230 is used to drive the engaging portion 223 to slide along the rail 213. In some embodiments, the driving mechanism 230 includes a motor 231 and a roller 233 coupled to an output shaft of the motor 231. The motor 231 is connected to the body 221, and the roller 233 is rotatably connected to the body 221 and attached to the guide rail 213 of the band 21. Motor 231 may be energized and cause roller 233 to roll relative to rail 213 to effect movement of functional module 22 on strap 21 using the friction between roller 233 and rail 213.

Further, the roller 233 may include a shaft 2331 and a rolling body 2333, the shaft 2331 is linked with the output shaft of the motor 231, and the rolling body 2333 is sleeved on the shaft 2331 and fixedly connected with the shaft 2331. The output shaft of the motor 231 may be connected to the rotation shaft 2331 of the roller 233, or may be linked to the rotation shaft 2331 of the roller 233 through an intermediate gear or a gear set. After the motor 231 is started, the rotating shaft 2331 is driven to rotate relative to the main body 221, and the rolling body 2333 is driven to rotate relative to the main body 221, so that the functional module 22 is moved on the binding band 21.

Further, a mounting groove (not shown) may be formed at one side of the body 220, and the rotation shaft 2331 is received in the mounting groove. The function module 22 includes a blocking plate 225, and the blocking plate 225 covers both ends of the rotation shaft 2331. The baffle 225 may be a metal baffle 225, which may be attached to the body 221, or may be fixed to the body 221 by means of magnetic attraction or the like. Of course, the baffle 225 may also be a metal injection molded part, so that the baffle 225 has relatively good rigidity and can be conveniently and fixedly connected with the main body part 221. The baffle 225 can provide a better limiting function for the roller 233, so as to improve the reliability of the operation of the roller 233.

Further, the functional module 22 may include a battery (not shown) and a wireless communication module (not shown), the battery may be a lithium battery capable of being repeatedly charged and discharged, and the battery is used for supplying power to the wireless communication module, the functional device and the driving mechanism 230. The functional device is in communicative connection with a wireless communication module for communicating with an external device or the electronic device 10 of the wearable device 100. Since the functional module 22 is communicatively connected to the electronic device 10 or the external device through the wireless communication module, the functional module 22 can be securely communicatively connected to the electronic device 10 or the external device at different positions of the strap 21, so as to improve the reliability of the operation.

In some embodiments, the wireless communication module is a Bluetooth (Bluetooth) communication unit. In other embodiments, the wireless communication module may be a wifi (wireless fidelity) communication unit, or a ZigBee communication unit, or an nfc (near Field communication) communication unit. Due to the adoption of the wireless communication module for data transmission, the functional module 22 can be reliably and communicatively connected with the electronic device 10 or an external device at different positions of the binding band 21 under normal conditions, so that the working reliability of the functional module 22 can be improved.

In the embodiment that the function module 22 includes the heart rate sensor, a detection window may be disposed on a side of the body 220 opposite to the attachment surface 211a, and the function module 22 may be driven by the driving mechanism 230 to move to a suitable position along the belt body 211, and be attached to the radial artery, the carotid artery, and the like to obtain relatively accurate heart rate data through measurement, and transmit the detection data to the electronic device 10 or the external device through the wireless communication module.

In an embodiment where the function module 22 includes a blood pressure sensor, a detection window may be disposed on a side of the body 220 facing away from the attachment surface 211a, the function module 22 may be driven by the driving mechanism 230 to move to a suitable position along the belt body 211, and a user may press a fingertip against the detection window, or press the detection window against an ear, a carotid artery, or the like, so as to obtain a relatively accurate blood pressure measurement value, and transmit the detection data to the electronic device 10 or an external device through the wireless communication module.

In embodiments where the functional module 22 includes a camera, the camera may capture image information and transmit the data to the electronic device 10 of the wearable device 100 or an external device via the wireless communication module. In embodiments where the functional module 22 includes a fingerprint sensor, the data of the fingerprint sensor may also be transmitted to the electronic device 10 or an external device through the wireless communication module.

Of course, it is understood that in some embodiments, the functional module 22 may be easily detached from the strap 21, and the detached functional module 22 may also be capable of maintaining a reliable communication connection with the electronic device 10 or an external device. The user can hold the functional module 22 with one hand and wear the electronic device 10 or hold an external device with the other hand, so as to improve the flexibility of the use of the functional module 22 and expand the use scene of the functional module 22. Taking the example where the functional module 22 includes a blood pressure sensor, the user can wear the electronic device 10 with one hand, hold the functional module 22 with the other hand and press against other parts of the body, such as the carotid artery, ears or fingertips, to measure blood pressure, and observe blood pressure parameters through the electronic device 10 to obtain more accurate measurements. Taking the example that the function module 22 includes a camera, the user can hold the function module 22 with one hand to take multi-angle and multi-scene shooting, and wear the electronic device 10 with the other hand to observe the shot images through the electronic device 10. When the functional module 22 includes other types of functional devices, the usage process is similar and will not be described herein.

The strap 21 of the strap assembly 20 described above may be connected to the electronic device 10 to wear the electronic device 10 to the wrist of the user through the strap assembly 20. Since these functional components are disposed on the strap 21, the internal installation space of the electronic device 10 can be saved, which is beneficial to the light and thin design of the electronic device 10. Since the functional module 22 is slidably engaged with the guide rail 213 of the strap 21 through the engaging portion 223 and can be driven by the driving mechanism 230 to move along the length extension direction of the strap body 211, the user can conveniently adjust the position of the functional module 22 on the strap 21, so as to improve the convenience and flexibility of the functional device, and is suitable for a wider population.

With continued reference to fig. 4, all of the functional modules 22 are located on one side of the tape 211. Further, all the functional modules 22 are located on the side of one of the abutting surface 211a and the outer surface 211c and spaced from the other. For example, in some embodiments, all of the functional modules 22 are located on the side of the outer surface 211c and spaced apart from the abutting surface 211 a. In other words, the functional module 22 can be partially embedded in the tape body 211 and spaced from the attachment surface 211a, so as to prevent the functional module 22 from protruding the attachment surface 211a and reducing the wearing comfort. In this embodiment, the attachment surface 211a may completely cover the functional module 22 to maintain the integrity of the attachment surface 211a and prevent liquids such as sweat on the wrist from easily flowing from the side of the attachment surface 211a to the functional module 22.

For another example, in other embodiments, all of the functional modules 22 are located on the side of the abutting surface 211a and spaced from the outer surface 211 c. In other words, the functional module 22 may be partially embedded in the band 211 and spaced apart from the outer surface 211c to prevent the functional module 22 from protruding out of the outer surface 211c, so as to provide the wearable device 100 with better appearance integrity. In such an embodiment, the outer surface 211c may completely cover the functional module 22 to maintain the integrity of the outer surface 211c and prevent liquids such as water, oil, etc. from easily flowing from the side of the outer surface 211c to the functional module 22. Of course, this structural arrangement also prevents foreign matter such as dust from easily entering the functional module 22 from the side where the outer surface 211c is located.

Referring to fig. 4, in the present embodiment, a gap exists between the adhering surface 211a of the tape body 211 and the engaging portion 223, and the adhering surface 211a shields the functional module 22. In other words, the portion of the tape body 211 for carrying the guide rail 213 has a certain thickness, so that the functional module 22 is entirely located on the side of the attaching surface 211a facing away from the wrist of the user. This arrangement can prevent the functional module 22 from pressing against the body of the user and reducing the wearing comfort.

Of course, in other embodiments, the attachment surface 211a may not block the functional module 22, and the functional module 22 may be prevented from being pressed against the body of the user by the gap between the attachment surface 211a and the engaging portion 223 in the thickness direction of the belt body 211. For example, the tape body 211 may be provided with a through slot, the guide rail 213 is provided in the through slot, and the engaging portion 223 of the functional module 22 is slidably engaged with the guide rail 213 in the through slot, so that at least a portion of the functional module 22 may be exposed to the side of the attaching surface 211a of the tape body 211. In this embodiment, the function module 22 may include a blood pressure sensor, a detection window of the blood pressure sensor may be exposed on the side of the adhesive surface 211a, and the blood pressure sensor may be moved to a suitable position, such as a position of a radial artery, relative to the belt body 211, so as to facilitate a user to measure blood pressure data in real time, and improve convenience of use.

In the present application, the bonding surface 211a is taken as an example to shield the functional module 22. Referring to fig. 4, the tape 211 is provided with a receiving groove 211b at a side opposite to the attachment surface 211a, the guide rail 213 is disposed in the receiving groove 211b, and at least a portion of the functional module 22 is received in the receiving groove 211b and can move along the receiving groove 211 b. Further, the guide rail 213 is adhered to a groove wall of the receiving groove 211 b. Specifically, in some embodiments, the belt body 211 is made of a silica gel material, and the belt body 211 made of the silica gel material has relatively good flexibility, so that the binding band 21 can be smoothly bent and fit with the body of a user, and the wearing comfort is further improved. In other embodiments, the belt body 211 may also be made of fluororubber or fabric or metal. The material of guide rail 213 can be plastic and guide rail 213 has relatively good toughness to make guide rail 213 can enough follow area body 211 bending deformation, can keep the direction and the limiting displacement to cooperation portion 223 again. Of course, other materials with suitable flexibility may be used for the guide rail 213. In the present application, the belt body 211 is made of silica gel, the guide rail 213 is made of plastic, and the surfaces of the guide rail 213 and the belt body 211 can be provided with a glue catching structure and adhered by the adhesive 215, so that the guide rail 213 can be reliably connected to the belt body 211. The adhesive grasping structure can be a rough surface formed by grooves, protrusions and the like, so that the belt body 211 or the guide rail 213 can be reliably connected with the adhesive 215 through the adhesive grasping structure.

Further, in some embodiments, opposite side groove walls of the accommodating groove 211b extend toward one end away from the attachment surface 211a, and except the groove wall of the accommodating groove 211b where the function module 22 is located, the groove wall of the accommodating groove 211b at other positions wraps the guide rail 213. At the position of the function module 22, the groove wall of the receiving groove 211b is pressed by the function module 22 to be expanded, so that the main body 220 is exposed on the side of the tape body 211 opposite to the attachment surface 211 a. The structure of the belt body 211 can form a complete appearance surface on the side of the belt body 211 opposite to the attaching surface 211a, so as to improve the appearance characteristics of the binding band 21 and prevent dust, liquid and the like from easily entering the accommodating groove 211 b. Of course, it is understood that the arrangement of the groove wall of the accommodating groove 211b to wrap the guide rail 213 is not necessarily required. For example, the receiving groove 211b may form a long and narrow opening on a side of the tape 211 opposite to the attaching surface 211a, so that at least a portion of the guide rail 213 is exposed on the side of the tape 211 opposite to the attaching surface 211a, thereby reducing sliding resistance of the function module 22 in the receiving groove 211 b.

In the embodiment where the strap 21 is provided with the receiving groove 211b, the body 220 may slightly protrude from an end of the strap 211 away from the attaching surface 211a, so as to facilitate a user to touch or drive the functional module 22 to move along the length extending direction of the strap 211. Further, on both sides of the belt body 211 in the width direction, the main body 220 and the engaging portion 223 may form a step-like structure, that is, the edge of the main body 220 forms a recessed structure, and one end of the belt body 211, which is far away from the attaching surface 211a, may be accommodated in the recessed structure, so as to form a half-pack structure for the functional module 22, so as to further limit the functional module 22 in the thickness direction of the belt body 211, and prevent the functional module 22 from easily coming out of the accommodating groove 211 b. Of course, such an arrangement is not necessary, and the body 220 may be flush with a side of the tape body 211 away from the attachment surface 211a, or an end of the tape body 211 away from the attachment surface 211a may protrude from the body 220. Of course, it is understood that the receiving groove 211b is not necessarily provided.

With reference to fig. 3 and 4, the engaging portion 223 includes a first arm 2231 and a second arm 2233 disposed opposite to each other, the first arm 2231 is connected to one side of the body 220, the second arm 2233 is connected to the other side of the body 220, and the first arm 2231 and the second arm 2233 are spaced apart from each other in the width direction of the strap body 211.

This structure can achieve both the sliding fit of the function module 22 with the guide rail 213 and the prevention of the function module 22 from easily coming off the strap 21, so that the reliable positioning of the function module 22 on the strap 21 can be achieved.

Referring to fig. 5, in another embodiment, the cross sections of the first extending portion a1 and the second extending portion a2 are both triangular, the end of the guide rail 213 away from the attachment surface 211a is configured to be wide at the top and narrow at the bottom, and the guide rail 213 forms a first receiving groove B1 and a second receiving groove B2 with triangular cross sections at two sides of the tape 211 in the width direction, respectively, for slidably engaging with the first extending portion a1 and the second extending portion a 2. The first arm 2231 and the second arm 2233 form a sliding slot 220a with the body 220, a side of the engaging portion 223 facing the attachment surface 211a may also have an opening 220b communicating with the sliding slot 220a, and a width of the opening 220b is smaller than a width of a side of the guide rail 213 away from the attachment surface 211 a. This structure can achieve both the sliding fit of the function module 22 with the guide rail 213 and the prevention of the function module 22 from easily coming off the strap 21, so that the reliable positioning of the function module 22 on the strap 21 can be achieved.

Referring to fig. 6, in another embodiment, the cross sections of the first extending portion a1 and the second extending portion a2 are both trapezoidal, the end of the guide rail 213 away from the attachment surface 211a is configured to be wide at the top and narrow at the bottom, and the guide rail 213 forms a first receiving groove B1 and a second receiving groove B2 with trapezoidal cross sections at two sides of the tape 211 in the width direction, respectively, for slidably engaging with the first extending portion a1 and the second extending portion a 2. The first arm 2231 and the second arm 2233 form a sliding slot 220a with the body 220, a side of the engaging portion 223 facing the abutting surface 211a may also have an opening 220b communicating with the sliding slot 220a, and a width of the opening 220b is smaller than a width of a side of the guide rail 213 away from the abutting surface 211 a. This structure can achieve both the sliding fit of the function module 22 with the guide rail 213 and the prevention of the function module 22 from easily coming off the strap 21, so that the reliable positioning of the function module 22 on the strap 21 can be achieved.

It is understood that in other embodiments, the first extension a1 and the second extension a2 may have other shapes such as a pentagon or other polygon or semicircle, and the portion of the guide rail 213 for slidably engaging with the first arm 2231 and the second arm 2233 may match the shape of the first arm 2231 and the second arm 2233.

Of course, the mating portion 223 may have other shapes. Referring to fig. 7, in some embodiments, the guide rail 213 defines a guide groove 213a, an end of the first arm 2231 away from the body 220 and an end of the second arm 2233 away from the body 220 are both disposed through the guide groove 213a, and a side of the first arm 2231 facing away from the second arm 2233 and a side of the second arm 2233 facing away from the first arm 2231 are both slidably engaged with the guide rail 213.

Specifically, in this embodiment, an end of the first arm 2231 away from the body 220 extends to a side away from the second arm 2233 to form a first extending portion a1, the guide groove 213a includes a first receiving groove B1 disposed at a side of the guide rail 213, and the first extending portion a1 is received in the first receiving groove B1. One end of the second arm 2233 away from the body 220 extends to a side away from the first arm 2231 to form a second extending portion a2, the guide groove 213a includes a second receiving groove B2 disposed on the opposite side of the guide rail 213, and the second extending portion a2 is received in the second receiving groove B2. During the sliding of the function module 22 along the guide rail 213, the first extending portion a1 is slidably engaged with the first receiving groove B1 to limit and guide the sliding of the function module 22 along the guide rail 213, and the second extending portion a2 is slidably engaged with the second receiving groove B2 to limit and guide the sliding of the function module 22 along the guide rail 213.

In this embodiment, the first support arm 2231 and the second support arm 2233 may be axially symmetric, and the cross section of the first extension a1 has one of a triangle shape, a rectangle shape and a trapezoid shape, and the shape of the cross section of the first receiving groove B1 matches the shape of the first extension a 1; the cross section of the second extending portion a2 is one of a triangle, a rectangle and a trapezoid, and the shape of the cross section of the second receiving groove B2 matches with the shape of the second extending portion a2, which is not described herein again.

Further, in this embodiment, a side of the guide rail 213 facing away from the abutting surface 211a has a notch 213b communicating with the guide groove 213a, and a width of the notch 213b is smaller than a width of an end of the fitting portion 223 far from the body 220. In other words, in this embodiment, the guide groove 213a is configured to be narrow at the top and wide at the bottom in the thickness direction of the belt body 211. Taking the example that the first extension a1 and the second extension a2 are both triangular in cross section, the guide groove 213a slidably engaged with the first arm 2231 and the second arm 2233 is formed in a dovetail groove shape. This structure can achieve both the sliding fit of the function module 22 with the guide rail 213 and the prevention of the function module 22 from easily coming off the strap 21, so that the reliable positioning of the function module 22 on the strap 21 can be achieved. In the embodiment where the cross-sections of the first extension a1 and the second extension a2 are in other shapes, the shape of the guide groove 213a may be matched with the shapes of the first extension a1 and the second extension a2, and the description thereof is omitted here.

Further, referring to fig. 8, in some embodiments, one of the belt body 211 and the function module 22 is provided with a magnet 241, and the other is provided with a magnetic engaging element 243, and the magnetic engaging element 243 is used for engaging the magnet 241, so that the positions of the function module 22 and the strap 21 are relatively fixed. Specifically, the magnetically attractive mating member 243 may be a magnetic metal member such as iron, cobalt, nickel, and alloys thereof. The magnetic engaging member 243 may be disposed on the body 220 or disposed on the engaging portion 223. The plurality of magnets 241 may be disposed at intervals on the wall of the receiving groove 211b, so that the functional module 22 can be reliably positioned at a plurality of positions where the magnets 241 are disposed.

Further, the application also discloses a control method of the wearable device 100. The processor of the electronic device 10 is configured to obtain the control command and activate the driving mechanism 230 according to the control command, and the driving mechanism 230 drives the functional module 22 to move along the length extension direction of the strap 21. Specifically, the control command may be generated by the user operating the display module 12 of the electronic device 10, for example, the display module 12 may display a virtual key, and when the virtual key is clicked, the processor may generate the control command, and respond to the control command and activate the motor 231 of the driving mechanism 230 to drive the function module 22 to move along the length extension direction of the strap 21 through the roller 233. As another example, the control command may be generated by a user operating a physical key of the electronic device 10. As another example, the control command may be generated by a voice operation of the user, i.e., the user operates the electronic device 10 by voice to generate the control command. After the electronic device 10 is fitted to the wrist of the user, a control command may be generated by operating the electronic device 10, thereby achieving automatic movement of the function module 22 in the strap 21, and thus improving convenience of use.

Further, in some embodiments, the functional device may be further configured to detect a relative position of the functional module 22 and the wrist, and the processor may be further configured to determine whether the relative position is a preset position, and to disconnect the control circuit of the driving mechanism 230 when the relative position is the preset position. Specifically, taking a blood pressure sensor as an example, the data measured by the blood pressure sensor at different positions of the wrist may be different, and generally, the better the alignment with the radial artery is, the more accurate the measured waveform and the measured result are. In this embodiment, the output waveform of the blood pressure sensor can be used to confirm whether the functional module 22 has moved to a predetermined position, i.e., a position well aligned with the radial artery. In other words, the processor may continuously adjust the position of the functional module 22 on the binding band 21 according to the output data of the functional device, for example, drive the motor 231 to rotate forward and backward to achieve forward and backward movement of the functional module 22 on the binding band 21 until the output waveform of the functional module 22 is relatively accurate, so as to confirm that the position is the preset position, and perform measurement at the preset position by using the functional module 22.

The heart rate sensor can be set by referring to the blood pressure sensor, and the details are not repeated here. In other embodiments, the preset position can also be determined by providing a sensor, such as a hall sensor, at the function module 22. For example, for a camera or a fingerprint sensor, when the electronic device 10 is normally worn and the display module 12 is aligned with the back of the hand, the sensor may be located at a central position on the inner side of the wrist (i.e. on the same side as the palm), and when the function module 22 moves to this position, the control circuit of the driving mechanism 230 is disconnected, so that the user may use the camera or the fingerprint sensor in a relatively relaxed posture, so as to improve the convenience of use.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
