In other embodiments, the locking member may also be a clip with elasticity, and the clip clamps the strap 20 passing through the hole under the condition of no external force, so that the functional module 30 is fixed at the position of the strap 20. When the position of the functional module 30 on the strap 20 needs to be adjusted, the position of the functional module 30 on the strap 20 can be adjusted by operating the clips to release the clamping of the strap 20.

The functional module 30 is connected with the strap 20, and the functional module 30 includes a housing 31 and a fingerprint module 32 disposed in the housing 31. With the utilization when the user dresses wearable device 100 in the wearing position of human body, the fingerprint identification effect that the utilization can conveniently pass through fingerprint module 32 accomplishes controlling main part 10. For example, the screen locking state of the display screen 11 is adjusted by the fingerprint module 32.

In particular, the housing 31 has a window 311 for placing a finger to facilitate the window 311 to adapt to the relevant operation needs. Fingerprint module 32 and control mainboard signal connection, fingerprint module 32 are used for carrying out fingerprint identification to placing in the finger of window 311 to acquire fingerprint information, the control mainboard is according to the lock screen state of fingerprint information regulation and control display screen 11 that fingerprint module 32 obtained.

The wearable device 100 of the present application, because the fingerprint module 32 is integrated in the functional module 30, and is connected with the bandage 20 through the functional module 30, thereby satisfying the fingerprint identification function, can make the functional device in the main body 10 set less, so as to benefit the frivolousness of the main body 10.

In some embodiments, as shown in fig. 3, the fingerprint module 32 includes a light emitting unit 321 and a light sensor 322. The light-sensitive surface of the light sensor 322 is opposite to the window 311, the light-emitting unit 321 is used for emitting infrared light, the window 311 can be penetrated by light, at least part of the light emitted by the light-emitting unit 321 is reflected to the light-sensitive surface of the light sensor 322 through a finger placed on the window 311, so that the light sensor 322 performs fingerprint identification on the finger. In this embodiment, since the light emitted from the light emitting unit 321 can be incident on the finger, the requirement of the sensor for performing fingerprint identification on the finger is satisfied, so that the wearable device 100 does not need to provide a device for implementing a fingerprint identification function in the main body 10, which is beneficial to the protection design of the main body 10.

The photosensor 322 has a photosensitive region that can produce a photoelectric effect when illuminated by light to form an image. Types of the light sensor 322 may include a CCD (charge coupled) element, a CMOS (complementary metal oxide conductor) device, a photodiode, and the like. The light sensor 322 may be a color light sensor 322, a monochromatic light sensor 322, an infrared light sensor 322, a gray scale sensor, and the like, divided by color. The type of the light sensor 322 is not limited herein, as long as it can receive the light reflected by the finger to realize fingerprint recognition.

In some embodiments, the fingerprint module 32 includes a capacitive fingerprint identification unit or a radio frequency fingerprint identification unit. For example, combine fig. 4 to show, when fingerprint module 32 is the electric capacity fingerprint identification unit, then need not to set up light emission unit 321 and light sensor 322, and only need set up the electric capacity coating film that satisfies the electric capacity fingerprint identification unit and carry out fingerprint identification to when pressing through the finger, realize obtaining fingerprint information through the mode of discernment capacitance tolerance. Specifically, the basic principle of fingerprint identification by the capacitance fingerprint identification unit is to collect fingerprints through the numerical value change of capacitance; because the fingerprint has concave-convex lines (the ridges are convex and the valleys are concave), when the finger contacts the fingerprint identification area of the capacitance fingerprint identification unit at the window 311, the fingerprint identification area will form different capacitance values with the ridges and the valleys of the finger. The current difference is detected according to the discharge speed of different capacitors, so that the positions of the ridges and the valleys can be detected to form fingerprint image data. In this embodiment, the window 311 may be formed as a groove provided in the housing 31 so that a finger can touch the fingerprint recognition area of the capacitive fingerprint recognition unit.

The fingerprint module 32 is not limited to the capacitive fingerprint identification unit and the radio frequency fingerprint identification unit. In some embodiments, the fingerprint module 32 may also be in other structural forms for implementing the fingerprint identification function, which are not described herein.

It should be noted that the functional module 30 is not limited to implement the fingerprint recognition function, and in some embodiments, the functional module 30 contacts the skin of the wearing part of the user through the biosensor disposed on the inner side surface 21 of the strap 20 to implement the monitoring of the health state of the body of the user. In some embodiments, the functional module 30 further includes a biosensor disposed on the outer side 22 of the strap 20, so that the user's own and other people's health status can be tested. The biosensor can be used for testing parameters such as blood pressure, heart rate, body temperature and the like, and monitoring data is fed back to the control mainboard of the main body 10 in a Bluetooth mode, a wireless radio frequency generator mode, a signal transmission antenna mode and the like, so that under the system of the control mainboard, the health condition is displayed in a display mode through the display screen 11, and a better health monitoring effect is achieved.

As shown in fig. 5, in some embodiments, the functional module 30 includes a light receiving unit 33, and at least a portion of the light emitted from the light emitting unit 321 is emitted from the window 311 and can be reflected to the light receiving unit 33 by a finger placed on the window 311, so that the light receiving unit 33 detects blood pressure of the finger, and thus the wearable device 100 can not only satisfy fingerprint identification to unlock the lock screen, but also can detect blood pressure by the light receiving unit 33, and the overall volume of the main body 10 is not increased, i.e., the light and thin design of the main body 10 is maintained under the condition of implementing multiple functions.

In this embodiment, because the light that light emission unit 321 was emergent, light demand when both can satisfying light sensor 322's fingerprint identification also can satisfy the light needs that light receiving unit 33 carried out the blood pressure detection time to improve light emission unit 321's utilization ratio, reduce optical device's the quantity that sets up simultaneously, so that reduce functional module 30's whole volume, make wearable device 100 whole small and exquisite, promote whole outward appearance feel.

In other embodiments, a part of the light emitted from the light emitting unit 321 and another part of the light from other optical elements are used as the light source of the light receiving unit 33 during blood pressure detection, so that the utilization rate of the light emitting unit 321 can be improved, and the overall luminous flux can be effectively increased, so that sufficient light is incident on the finger and reflected to the light receiving unit 33 during blood pressure detection of the light receiving unit 33, thereby improving the accuracy of blood pressure detection. For example, the functional module 30 includes a light receiving unit 33 and an infrared light source 34, the infrared light source 34 is used for emitting infrared light, light emitted from the infrared light source 34 at least partially exits from the window 311 and can be reflected to the light receiving unit 33 by a finger placed on the window 311, and light emitted from the light emitting unit 321 at least partially exits from the window 311 and can be reflected to the light receiving unit 33 by the finger placed on the window 311, so that the light receiving unit 33 can detect blood pressure of the finger.

Note that, when the function module 30 of the wearable device 100 is integrated with the fingerprint recognition and blood pressure detection functions. The wearable device 100 comprises a clock module electrically connected with the control mainboard, the clock module is used for detecting the stay time of the finger at the window 311 and generating a clock signal corresponding to the stay time, when the clock module detects that the stay time of the finger at the window 311 is less than a preset threshold and greater than zero, a first clock signal is generated, and the control mainboard controls the optical sensor 322 to perform fingerprint identification according to the first clock signal; when the clock module detects that the staying time of the finger at the window 311 is greater than or equal to a preset threshold, a second clock signal is generated; the control main board controls the light receiving unit 33 to detect the blood pressure according to the second clock signal.

The time of the finger staying in the window 311 is detected by the clock module, and the time of blood pressure monitoring and fingerprint detection is effectively matched, so that different functions can be realized by fully utilizing the function module 30 without resource waste, for example, when fingerprint identification is not required, the fingerprint identification operation is erroneously executed, or when blood pressure detection is not required, the blood pressure detection is erroneously executed.
