The external device may be a smartphone, tablet, laptop, desktop, or other type of terminal device. The battery 215 is provided in the housing 211 and is used to supply power to the functional device 213, and the battery 215 may be a lithium battery capable of being repeatedly charged and discharged many times. The coil module 217 is electrically connected to the battery 215 and is configured to couple with the electronic device 10, so that the electronic device 10 can wirelessly charge the battery 215. In other words, the electronic device 10 of the wearable device 100 may include the transmitting coil 15, and the transmitting coil 15 is electrically connected with the power module of the electronic device 10. The electronic device 10 can generate a magnetic field through the transmitting coil 15, and the coil module 217 of the functional module 21 can generate an induced current in the magnetic field, so that the electromagnetic induction of the transmitting coil 15 and the coil module 217 is utilized to transmit current between the electronic device 10 and the functional module 21, the electronic device 10 is utilized to wirelessly charge the functional module 21, and the charging convenience of the functional module 21 is improved.

Referring to fig. 5 in combination with fig. 6, in the present embodiment, one end of the housing 211 is provided with a through hole 211b, the opposite end of the housing 211 is provided with a mounting groove 211c, the mounting groove 211c is used for connecting the first section 23 of the binding band, and the through hole 211b is used for penetrating the second section 25 of the binding band. One end of the first section 23 may be rotatably connected to one end of the electronic device 10, for example, by a clasp to rotatably connect the first section 23 to the electronic device 10. The opposite end of the first segment 23 is rotatably connected to one end of the housing 211 and is at least partially received in the mounting groove 211c, for example, by an elastic pin. One end of the second segment 25 may be pivotally connected to the opposite end of the electronic device 10 via a clasp.

In this embodiment, the free end of the second segment 25 (i.e. the end far away from the electronic device 10) can be inserted through the through hole 211b of the housing 211 and go around the end of the housing 211 far away from the mounting groove 211c, and then fixed to another position of the second segment 25, so that the first segment 23, the functional module 21, the second segment 25 and the electronic device 10 jointly enclose and form the receiving space 105 for inserting the wrist (see fig. 1 and 2 for the receiving space 105). For example, the free end of the second section 25 may be provided with a buckle, the second section 25 may be provided with a plurality of clamping holes at intervals along the length direction thereof, and after the buckle is clamped into the clamping hole, the free end of the second section 25 can be fixed, so that the size of the accommodating space 105 for penetrating the wrist of the user can be easily adjusted. Of course, the second segment 25 may also be provided with a magnet, the second segment 25 may be provided with a plurality of adsorbing members along the length direction thereof, and the adsorbing members and the magnet are attracted to each other, so that the free end of the second segment 25 can be fixed. The magnet may be a magnet, and the adsorbing member may be a magnet, or a magnetic metal member such as iron, cobalt, nickel, and alloys thereof.

In other embodiments, the wearable device 100 may further include another strap, i.e., the strap may include three sections, and the other strap is connected to an end of the housing 211 away from the electronic device 10, i.e., the functional module 21 is disposed between the first section 23 and the other section of the strap. In this embodiment, the free end of the second section 25 and the free end of the other strap can also form a receiving space 105 for passing through the wrist of the user.

In other embodiments, the housing 211 may be directly connected to the electronic device 10, for example, the housing 211 of the functional module 21 may be detachably connected to the middle frame 11 of the electronic device 10. In other words, one end of the housing 211 may be used to connect to the electronic device 10, and the opposite end of the housing 211 may be used to connect to a strap. In such an embodiment, the outer shell 211 of the functional module 21 and the middle frame 11 of the electronic device 10 may be provided with corresponding mating structures to facilitate the detachment of the functional module 21 from the electronic device 10. For example, the middle frame 11 of the electronic device 10 may be provided with a retractable thimble, the outer shell 211 of the function module 21 is provided with a connection hole, and the thimble penetrates through the connection hole to realize the assembly of the electronic device 10 and the function module 21; the functional module 21 can be detached from the electronic device 10 by withdrawing the thimble from the connecting hole.

In other embodiments, the opposite ends of the housing 211 may be provided with through holes 211b, and the through holes 211b are used for penetrating the binding belt, so that the functional module 21 is slidably disposed on the binding belt. In other words, in this embodiment, the strap may be passed through the through hole 211b at one end of the housing 211 and out through the through hole 211b at the opposite end of the housing 211 so that the functional module 21 may be slidably provided to the strap. Such an embodiment can easily adjust the position of the functional module 21 on the strap, and facilitate the assembly of the functional module 21 with the strap, and can more easily accomplish the detachment of the functional module 21 from the strap. In other embodiments, other structures may be adopted to achieve convenient detachment and installation of the functional module 21 and the strap, so as to improve convenience of use.

Referring again to fig. 5, the functional module 21 may include a wireless communication unit 214. Both the functional device 213 and the wireless communication unit 214 are provided to the housing 211, and the wireless communication unit 214 is used for communicating with an external device or the electronic device 10 of the wearable device 100. Since the function module 21 is communicatively connected to the electronic device 10 or the external device through the wireless communication unit 214, the function module 21 can be reliably communicatively connected to the electronic device 10 or the external device under normal conditions, so as to improve the reliability of operation. The functional device 213 may include one or more of a heart rate sensor, a blood pressure sensor, a camera, a fingerprint sensor, etc. 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.

In some embodiments, the wireless communication unit 214 is a Bluetooth (Bluetooth) communication unit. In other embodiments, the Wireless Communication unit 214 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 unit 214 for data transmission, the functional module 212 can be reliably and normally connected with the electronic device 10 or an external device, so that the reliability of the operation of the functional module 21 can be improved.

In the embodiment that functional module 21 includes the heart rate sensor, functional module 21 can set up the collection window, and functional module 21 can laminate to parts such as radial artery, carotid artery through the collection window and measure and obtain relatively accurate heart rate data to through wireless communication unit 214 with detection data transmission to electronic equipment 10 or external equipment.

In an embodiment where the functional module 21 includes a blood pressure sensor, the functional module 21 may set a collection window, and the user may press a fingertip against the collection window, or press the collection window against an ear, a carotid artery, or the like, 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 unit 214.

In an embodiment where the function module 21 includes a camera, the function module 21 may also be provided with a capture window, and the camera may capture image information through the capture window and transmit the data to the electronic device 10 of the wearable device 100 or an external device through the wireless communication unit 214. In embodiments where the functional module 21 includes a fingerprint sensor, the fingerprint sensor may also collect fingerprint data of the user through the collection window and transmit the fingerprint data to the electronic device 10 or an external device through the wireless communication unit 214.

Of course, it is understood that in some embodiments, the functional module 21 may be more easily detached from the strap, or the strap assembly 20 may be more easily detached from the electronic device 10, and the detached functional module 21 may also be capable of being reliably communicatively connected to the electronic device 10 or an external device through the wireless communication unit 214. Taking the example that the function module 21 is detached from the strap, after the function module 21 is detached from the strap, the user can hold the function module 21 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 using the function module 21 and expand the use scene of the function module 21.

Taking the example where the functional module 21 includes a blood pressure sensor, the user can wear the electronic device 10 with one hand, hold the functional module 21 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. Compared with the related art in which the blood pressure measurement is performed on the wrist and the wearable device 100 needs to be worn well, the functional module 21 of the present embodiment can transmit the blood pressure measurement data to the external device or the electronic device 10 of the wearable device 100 through the wireless communication module 214, so that the measurement flexibility can be improved. Compared with the scheme of measuring the blood pressure at the wrist in the related art, the functional module 21 of the embodiment can obtain more accurate blood pressure measurement values by measuring the blood pressure at the body parts such as the neck, the ears or the fingertips, and therefore the accuracy of the blood pressure measurement can be improved. The function module 21 of this embodiment does not need to be detached from the electronic device 10 and moved along with the function module 21 during the blood pressure measurement by the user through the function module 21, so that convenience of use can be improved and flexibility and accuracy of blood pressure detection can also be improved.

In embodiments where the strap assembly 20 is readily detachable from the electronic device 10, the user may detach the strap assembly 20 from the electronic device 10 and attach the functional module 21 to a body part such as the neck, ears, or fingertips for blood pressure measurement. This way, the flexibility of measurement can be improved, and the accuracy of blood pressure measurement can be improved.

Since the function module 21 for detecting blood pressure is no longer integrated with the electronic device 10 of the wearable device 100, 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. Moreover, since the functional module 21 for detecting blood pressure is no longer integrated with the electronic device 10 of the wearable device 100, the functional module 21 is no longer limited by the installation space of the electronic device 10, and therefore a blood pressure detecting element with stronger performance can be adopted to improve the accuracy of blood pressure measurement. Of course, it can be understood that the functional module 21 of the present application can also measure the blood pressure at the wrist of the user, and can also improve the accuracy of the measurement.

Taking the example that the function module 21 includes a camera, the user can hold the function module 21 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. In embodiments where the functional module 21 includes other types of functional devices 213, the usage process is similar and will not be described here.

The above-described function module 21 may be mounted to a strap of the electronic device 10 through the case 211 to wear the electronic device 10 to a wrist of a user through the strap. The functional device 213 may include one or more of a heart rate sensor, a blood pressure sensor, a camera, a fingerprint sensor, etc. Since these functional devices 213 are disposed on the strap, the internal installation space of the electronic device 10 can be saved, which is beneficial for the light and thin design of the electronic device 10. Since the functional module 21 includes the battery 215 and the coil module 217, the coil module 217 can be coupled to the electronic device 10 to wirelessly charge the battery 215 of the functional module 21 by using the electronic device 10, such an arrangement can save the cost of the charger of the functional module 21 and improve the charging convenience of the functional module 21, so that the functional module 21 can maintain sufficient electric quantity and improve the use convenience.

Since the functional module 21 can be coupled with the electronic device 10 through the coil module 217 for wireless charging and can wirelessly communicate with an external device or the electronic device 10 through the wireless communication unit 214, the functional module 21 does not need to be provided with a data and charging interface with a physical entity. For example, the functional module 21 need not be provided with exposed metal contacts for transmitting data or current. The functional module 21 does not need to be equipped with a separate charger, so that the cost of the device can be saved, and the need to carry both the charger of the electronic device 10 and the charger of the functional module 21 when going out can be avoided, so that the portability and the convenience of use of the wearable device 100 can be improved. Of course, it can be understood that, since the functional module 21 is provided with the battery 215 and the coil module 217, the functional module 21 can also be coupled with other devices having a wireless charging function through the coil module 217 to perform wireless charging, and the devices having the wireless charging function may be, but are not limited to, a smart phone, a mobile power supply, and the like.

With continued reference to fig. 5, the function module 21 may further include a circuit board 216, the battery 215 is electrically connected to the circuit board 216, and the function device 213 and the wireless communication unit 214 are connected to the circuit board 216.

The housing 211 may include a carrier 2113 and a cover 2115, the cover 2115 covers one end of the carrier 2113 and encloses with the carrier 2113 to form a receiving cavity, the battery 215, the functional device 213, and the coil module 217 may all be disposed in the receiving cavity, and the carrier 2113 is used for connecting a strap. Further, the cover 2115 is provided with a capture window, after the electronic device 10 and the functional module 21 are worn on the wrist of the user, the cover 2115 is located on the side of the carrier 2113 facing away from the wrist, and the cover 2115 is located on the side of the carrier 2113 facing away from the receiving space 105.

In other words, after the electronic device 10 is worn on the wrist of the user, the cover 2115 is located on the side of the carrier 2113 facing away from the wrist, and the acquisition window is located facing away from the wrist. In the process of measuring blood pressure, the user does not need to take the wearable device 100 off the wrist, and can directly use the fingertip of the other hand to be attached to the detection window of the cover plate 2115, so that blood pressure measurement can be performed, and the convenience of use is improved. Of course, in this embodiment, the user may also attach the blood pressure detection module 210 to other parts of the body, such as the neck or the ear, in the wearing state to measure the blood pressure, and this embodiment may also improve the convenience of detection. In the process of measuring the heart rate or collecting images and fingerprints, the collection window of the functional module 21 is arranged back to the wrist, so that the flexibility and convenience of use can be prompted, and further description is omitted here.

Of course, in other embodiments, for the functional module 21 with functions of blood pressure measurement and heart rate measurement, after the electronic device 10 is worn on the wrist of the user, the collection windows of the blood pressure measurement unit and the heart rate measurement unit may face the wrist of the user. In this embodiment, the blood pressure detection unit or the heart rate measurement unit may measure the blood pressure of the user in real time to improve convenience of use. In particular, for patients suffering from or at risk of suffering from blood pressure or heart related diseases, such as elderly people or patients with high blood pressure or heart disease, the function module 21 of this embodiment can measure the blood pressure or the heart rate in real time and provide a health reminder in time.

With reference to fig. 5, in the present embodiment, the carrier 2113 includes a frame 2113a and a bottom cover 2113b, the bottom cover 2113b is disposed on a side of the frame 2113a facing away from the cover 2115, and the bottom cover 2113b, the frame 2113a and the cover 2115 together enclose a receiving cavity. The bottom cover 2113b is attached to the electronic device 10, so that the coil module 217 is coupled to the electronic device 10, and the electronic device 10 is further utilized to wirelessly charge the functional module 21. For example, the functional module 21 may include a magnetic element 218, the magnetic element 218 is disposed on the bottom cover 2113b, the electronic device 10 may include a magnetic engaging element (not shown), and the magnetic element 218 is used for attracting the magnetic engaging element of the electronic device 10, so that the bottom cover 2113b of the functional module 21 is reliably attached to the electronic device 10, and the transmitting coil 15 of the electronic device 10 and the coil module 217 of the functional module 21 are aligned accurately, so as to improve the efficiency of wireless charging. The magnetically attractive mating member may be a magnetic metal member such as iron, cobalt, nickel and alloys thereof. Of course, the magnetically engaging member may be a magnet.

With reference to fig. 7, in the using process of the wearable device 100, when the function module 21 needs to be charged, the wearable device 100 only needs to be taken down from the wrist, the bottom cover 2113b of the function module 21 is attached to the rear shell 13 of the electronic device 10, the function module 21 and the electronic device 10 can be attracted and aligned by the magnetic attraction element 218 and the magnetic attraction engagement element, and the electronic device 10 is used for wirelessly charging the function module 21. In other words, the wearable device 100 of the present application only needs to carry the charger of the electronic device 10 during normal use, and during business trip or traveling, the burden of the user can be reduced, and the user does not need to worry about the charging problem of the functional module 21, so that the user experience is better.

The bottom 2113b may be made of the same material as that of the housing 2113a, and for example, the bottom 2113b and the housing 2113a may be made of stainless steel, plastic, glass, ceramic, or the like. The bottom cover 2113b may be made of a material different from that of the frame 2113a, for example, the frame 2113a may be a stainless Metal MIM (Metal injection Molding), and the bottom cover 2113b may be a ceramic or glass member.

The bottom cover 2113b may be contoured to match the shape of the wrist so that the blood pressure detecting module 210 can fit the wrist better. For example, the side of the bottom cover 2113b facing away from the cover plate 2115 may be contoured to provide a better fit of the surface of the bottom cover 2113b to the wrist of the user and to promote comfort of wear. It is understood that, since the function module 21 has relatively less functions, the external dimension thereof can be set relatively smaller to improve the appearance characteristics of the wearable device 100. For example, the width of the housing 211 of the functional module 21 may be close to the width of the strap to improve the appearance of the wearable device 100 and avoid a large influence on the bending of the strap to reduce the wearing comfort.

Referring to fig. 8 in conjunction with fig. 5, in some embodiments, the functional module 21 may further include a charging terminal 219 electrically connected to the circuit board 216, the charging terminal 219 is exposed at a side of the bottom cover 2113b facing away from the cover plate 2115, and the charging terminal 219 may be used to connect an external charger to charge the battery 215 of the functional module 21 with the charger. Of course, since the function module 21 includes the coil module 217 for wirelessly charging the battery 215, the charging terminal 219 is not necessary and may be absent. In the embodiment of the default charging terminal 219, since the bottom cover 2113b does not need to be provided with the opening of the charging terminal 219, it is possible to improve the waterproof and dustproof performance of the functional module 21, and to improve the appearance integrity and the simplicity of the functional module 21.

In some embodiments, the coil module 217 is wound by copper wire to form a spiral shape, and the coil module 217 may be fixedly connected to the bottom cover 2113b by glue. In some embodiments, the circuit board 216 and the battery 215 may be disposed side by side in the bottom cover 2113b and fixedly coupled to the bottom cover 2113b, and the coil module 217 may extend along an edge of the bottom cover 2113b and be disposed around the circuit board 216 and the battery 215. This structure can prevent the thicknesses of any two of the circuit board 216, the battery 215 and the coil module 217 from being overlapped, so that the overall thickness of the functional module 21 can be reduced, and the design of the functional module 21 with lightness, thinness and miniaturization can be realized. This structure can also avoid the adverse effect of the coil module 217 on the circuit board 216 and the battery 215 due to heat generation during the charging process.

In other embodiments, the coil module 217 may be formed on the bottom cover 2113b by using a Laser Direct Structuring (LDS) process, so as to simplify the processing of the coil module 217. In this embodiment, the coil module 217 may be formed on the inner surface of the bottom cover 2113b, or may be formed on the outer surface of the bottom cover 2113b, i.e., on the side of the bottom cover 2113b facing away from the cover 2115. Of course, both the inner surface and the outer surface of the bottom cover 2113b may form the coil module 217 through the LDS process, so as to improve the efficiency of wireless charging. In this embodiment, the coil module 217 is not limited to a planar area, for example, the coil module 217 may be disposed entirely on the planar area of the bottom cover 2113b, may be disposed entirely on the curved area of the bottom cover 2113b, or may extend from the planar area of the bottom cover 2113b to the curved area of the bottom cover 2113b. This arrangement makes full use of the shape of the housing 211 to improve the structural compactness of the functional module 21 and further reduce the overall size of the functional module 21.

Further, in the present invention, the application also discloses a charging method of the wearable device 100. The processor of the electronic device 10 is configured to obtain the control command and switch on the control circuit of the transmitting coil 15 according to the control command, so that the transmitting coil 15 is available to couple with the coil module 217 of the functional module 21, thereby enabling the power module of the electronic device 10 to wirelessly charge the battery 215 of the functional module 21. Specifically, the control command may be generated by a user operating the display screen module 12 of the electronic device 10, for example, the display screen module 12 may display a virtual key, and after the user clicks the virtual key, the control command may be generated, and the processor may switch on the control circuit of the transmitting coil 15 in response to the control command, so as to implement the power sharing function by using the electronic device 10. 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 worn on the wrist of the user, the electronic device 10 can be operated to generate a control command, so that the power sharing function of the electronic device 10 is realized, and the convenience in use is improved.

Further, in some embodiments, at least one of the electronic device 10 and the functional module 21 may be provided with a sensor for communicative connection with the processor to detect the relative position of the functional module 21 at the electronic device 10. The processor is further configured to determine whether the relative position of the functional module 21 in the electronic device 10 is a preset position, and to switch on the control circuit of the transmitting coil 15 when the relative position is the preset position. The sensor may be a hall sensor or a photoelectric sensor, and may be disposed on the electronic device 10 or the functional module 21.

Taking a hall sensor as an example, the hall sensor may be disposed on the functional module 21 to avoid occupying an installation space inside the electronic device 10, so as to facilitate the light and thin design of the electronic device 10. The hall sensor can judge the relative position of the electronic device 10 and the functional module 21 according to the strength of the magnetic field. For example, when the functional module 21 is attached to the preset position of the rear shell 13 of the electronic device 10, the hall sensor may generate a trigger signal, and the processor may determine that the functional module 21 is located at the preset position relative to the electronic device 10 according to the trigger signal, and then switch on the control circuit of the transmitting coil 15 of the electronic device 10, so as to implement the automatic power sharing function of the electronic device 10 and improve the convenience of use. In other words, in this embodiment, when the function module 21 is attached to the predetermined position of the rear case 13 of the electronic device 10, the electronic device 10 can automatically perform the power sharing function, so as to wirelessly charge the function module 21 by using the electronic device 10. In the embodiment that the hall sensor is disposed in the electronic device 10, the hall sensor may also be utilized to generate a trigger signal, so as to implement an automatic power sharing function of the electronic device 10, which is not described herein again.

Taking the photo sensor as an example, the photo sensor may be disposed on the functional module 21 to avoid occupying an installation space inside the electronic device 10, so as to facilitate a light and thin design of the electronic device 10. The photoelectric sensor can judge the relative position of the electronic device 10 and the functional module 21 according to the optical signal. For example, when the functional module 21 is attached to a preset position of the rear housing 13 of the electronic device 10, the photoelectric sensor may generate a trigger signal, and the processor may determine that the functional module 21 is located at the preset position relative to the electronic device 10 according to the trigger signal, and then switch on the control circuit of the transmitting coil 15 of the electronic device 10, so as to implement the automatic power sharing function of the electronic device 10. In particular, in the embodiment where the rear shell 13 of the electronic device 10 is provided with the detection window, or the bottom cover 2113b of the function module 21 is provided with the detection window, the relative position between the function module 21 and the electronic device 10 may also be detected by an optical element of the electronic device 10 or an optical element of the function module 21 (for example, an optical element of a heart rate sensor, a blood pressure sensor, or the like), so as to generate a trigger signal, thereby implementing an automatic power sharing function of the electronic device 10, and improving convenience of use. In the embodiment where the photoelectric sensor is disposed in the electronic device 10, the photoelectric sensor may also be utilized to generate a trigger signal to implement an automatic power sharing function of the electronic device 10, which is not described herein again.

Of course, in other embodiments, other sensors, such as a pressure sensor, may be used to detect the relative position between the electronic device 10 and the function module 21, and further used to generate a trigger signal, so as to implement the automatic power sharing function of the electronic device 10.

It will be appreciated that the sensor described above may also be used to generate a further trigger signal for opening the control circuit of the transmitting coil 15 of the electronic device 10. Specifically, after the user takes the functional module 21 away from the rear case 13 of the electronic device 10, the processor of the electronic device 10 may disconnect the control circuit of the transmitting coil 15 by detecting the distance with the help of the hall sensor or the photoelectric sensor, so as to reduce the power consumption of the electronic device 10.

It is understood that the transmitting coil 15 of the electronic device 10 in the present application may also be a receiving coil of the electronic device 10. For example, when the electronic device 10 is used to wirelessly charge the functional module 21, the transmitting coil 15 of the electronic device 10 functions to radiate magnetic field energy to the outside; when the electronic device 10 is wirelessly charged by another charger, the transmitting coil 15 of the electronic device 10 functions to receive magnetic field energy.

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 application shall be subject to the appended claims.
