The housing 20 includes a front case 21 and a bottom case 22 connected. The bottom shell 22 of the housing 20 may face or be in contact with the skin of the user when the user is wearing the wearable device 10. The circuit board 30, the vital signs sensor 40, and the first light barrier 50 are disposed within the housing 20. The housing 20 can form a shield for the circuit board 30, the first light barrier 50, and the condition sensor 40.

The display module 60 may include a display screen, a touch electrode and a transparent cover. The display screen has a display area for displaying image information. The display module 60 is connected to the housing 20. Specifically, the display module 60 may be disposed on the front case 21. The display area of the display screen is exposed to facilitate presentation of image information to a user. The display screen of the embodiment of the present application may be, but is not limited to, a liquid crystal display.

In some implementations, the display module 60 may be circular or rectangular. The embodiment of the present application does not limit the specific shape of the display module 60.

The circuit board 30 is located inside the display module 60. The circuit board 30 may be located between the display module 60 and the bottom case 22, so that the circuit board 30 is not easily visible to a user outside the wearable device 10. The circuit board 30 includes electronic devices (not shown in the drawings). The Circuit Board 30 may be a Printed Circuit Board (PCB). The electronic device may include, but is not limited to, a wireless charging chip, a smart algorithm chip, or a Power Management IC (PMIC). The circuit board 30 and the bottom chassis 22 have a mounting space therebetween. In some implementations, the circuit board 30 can be adhesively attached to the housing 20. In some examples, a surface of the circuit board 30 facing the bottom case 22 may be adhesively connected with the housing 20.

The main board 90 may be disposed inside the housing 20 so that the main board 90 is not easily visible to a user outside the wearable device 10. The circuit board 30 is electrically connected to the motherboard 90, so that data interaction between the circuit board 30 and the motherboard 90 is possible. In some realizable manners, the main board 90 may be disposed at a side of the display module 60 facing the circuit board 30. However, it should be understood that the specific location of the main plate 90 is not limited in the embodiment of the present application. The main board 90 is provided with electronic devices. For example, the electronic device may include, but is not limited to, a Central Processing Unit (CPU).

A condition sensor 40 is disposed within housing 20. The wearable device 10 can acquire the sign information of the user through the sign sensor 40, such as heart rate, pulse or blood oxygen, so that the user can perform health management according to the sign information. The condition sensor 40 includes a light emitting element 41 and a light receiving element 42. The light emitting element 41 may emit light toward the skin of the user. A portion of the light is absorbed by the user's skin and another portion is reflected by the user's skin. The reflected portion of the light is received by the light receiving element 42.

In some examples, the vital sign sensor 40 of embodiments of the present application may be a PPG (Photo Plethysmo Graph) sensor.

Fig. 6 schematically shows a partially exploded structure of the wearable device 10 according to an embodiment of the present application. Referring to fig. 4 to 6, the first light-shielding member 50 is disposed on a side of the circuit board 30 facing the bottom chassis 22. The first light-shielding member 50 is located between the circuit board 30 and the bottom case 22 in the thickness direction X of the wearable device 10. The bottom chassis 22, the first light-shielding member 50 and the circuit board 30 are connected to each other. The first light-blocking member 50 includes an accommodation hole 50a. Illustratively, the receiving hole 50a may be a through hole penetrating the first light blocking member 50 in the thickness direction X of the wearable device 10. The thickness direction X of the wearable device 10 refers to a stacking direction of the bottom case 22, the circuit board 30, and the display module 60.

The light emitting element 41 and the light receiving element 42 of the vital sign sensor 40 are both disposed on the side of the circuit board 30 facing the bottom case 22. The light emitting element 41 is located in the receiving hole 50a of the first light blocking member 50, and the light receiving element 42 is located outside the first light blocking member 50 facing away from the light emitting element 41, so that the first light blocking member 50 can separate the light emitting element 41 and the light receiving element 42. The first light-blocking member 50 of the embodiment of the present application can block the light emitted in the radial direction of the accommodating hole 50a from directly entering the light-receiving element 42, so as to avoid the crosstalk condition that the light emitted from the light-emitting element 41 directly enters the light-receiving element 42, and reduce the possibility of the detection result distortion caused by the crosstalk condition.

The light emitting element 41 includes a light emitting unit (not shown in the figure). The light-emitting surface of the light-emitting unit faces the bottom lens. The light emitting unit may emit light such as laser light, visible light (e.g., green or red light), infrared light, or the like in an energized state. Illustratively, the light emitting unit may include, but is not limited to, a Light Emitting Diode (LED). When the vital sign sensor 40 needs to collect the user vital sign information, the light emitting unit of the light emitting element 41 may emit light to the skin of the user. The receiving hole 50a of the first light-shielding member 50 can be closed to the light-emitting element 41, and it is ensured that the light emitted from the light-emitting element 41 is not blocked by the first light-shielding member 50. A portion of the light is absorbed by the user's skin and a portion is reflected by the user's skin. The reflected portion of the light is received by the light receiving element 42 located outside the first light-shielding member 50.

In some realizable manners, as shown in fig. 4, the bottom shell 22 of the housing 20 includes a bottom lens 221. The bottom lens 221 has good light transmittance. The first light-blocking member 50 is disposed on a side of the circuit board 30 facing the bottom lens 221. The bottom lens 221, the first light-shielding member 50 and the circuit board 30 are connected to each other. The light emitting element 41 and the light receiving element 42 are disposed corresponding to the bottom lenses 221, respectively. The light emitted from the light emitting element 41 may pass through the bottom lens 221. Light reflected from the skin of the user may pass through the bottom lens 221 and be incident at the light receiving element 42. Illustratively, the material of the bottom lens 221 may be plastic or glass.

The wearable device 10 is internally provided with a battery 70. For example, the battery 70 may be a lithium ion battery. The battery 70 can provide electric energy for the physical sign sensor 40, the display module 60, or the electrocardiograph monitor 80. The battery 70 is located on a side of the circuit board 30 facing away from the bottom case 22. The battery 70 may be disposed between the display module 60 and the circuit board 30. In some examples, the wearable device 10 with wireless charging functionality may charge the battery 70 without the use of wires, thereby providing convenience of use to the user. For example, the wearable device 10 may be connected to an external charging base (not shown) to charge the battery 70. When the user needs to use the wearable device 10, an external force may be applied to the wearable device 10 to separate the wearable device 10 from the charging cradle while the charging is stopped.

The wearable device 10 can collect information related to the electrocardiogram of the user through the electrocardiogram monitor 80, so that the user can perform health management according to the sign information. The electrocardiac monitor 80 comprises a first ring electrode 81. The first ring electrode 81 is disposed on a side of the bottom lens 221 facing away from the circuit board 30. The first ring electrode 81 is electrically connected to the circuit board 30. When the user wears the wearable device 10, the first ring electrode 81 may be in contact with the skin of the user to acquire an electrical signal related to an electrocardiogram. The electrical signals collected by the first ring electrode 81 can be transmitted to the circuit board 30 for data processing. The first ring electrode 81 has an outer surface facing away from the circuit board 30. The outer surface of the first ring electrode 81 may be for contact with the skin of the user.

The wearable device 10 of the embodiment of the application can simultaneously acquire the sign information of the user through the sign sensor 40 and the electrocardio monitor 80, and is favorable for the user to perform health management according to the sign information. The electrocardiac monitor 80 comprises a first ring electrode 81 for contact with the skin of the user. Because the first ring-shaped electrode 81 is in a ring-shaped structure, the contact area with the skin of the user can be increased, and different areas on the first ring-shaped electrode 81 can be in contact with the skin of the user, so that the first ring-shaped electrode 81 of the electrocardiogram monitor 80 is not easy to be completely separated from the contact state with the skin of the user in the process that the user touches the wearable device 10 or uses the wearable device 10, but a part or the whole of the first ring-shaped electrode 81 is always kept in the contact state with the skin of the user, thereby reducing the possibility that the data acquisition accuracy of the electrocardiogram monitor 80 is reduced and the generated electrocardiogram is distorted due to the completely separated contact state of the first ring-shaped electrode 81 and the skin of the user.

In some realizable manners, the first ring electrode 81 may be, but is not limited to, a ring shape, so that the ring-shaped first ring electrode 81 may be beneficial to improve the aesthetic sense of the wearable device 10 and improve the user satisfaction.

In some realizable manners, the first ring electrode 81 is a light-blocking structure. The first ring-shaped electrode 81 can effectively block light or absorb light. The first annular electrode 81 can reduce the possibility that the light emitted from the light emitting element 41 is incident on the light receiving element 42 in a reflected or refracted manner in the bottom lens 221, thereby reducing the possibility that the light emitted from the light emitting element 41 is directly incident on the light receiving element 42 to cause crosstalk.

Since the first ring-shaped electrode 81 has a function of preventing crosstalk between the light emitting element 41 and the light receiving element 42 and a function of collecting user sign information, it is not necessary to provide the first ring-shaped electrode 81 and a light blocking structure (for example, black ink) on the bottom lens 221 at the same time. If the first ring-shaped electrode 81 and the light-shielding structure are disposed on the bottom lens 221 at the same time, in order to avoid the light-shielding structure from affecting the contact between the first ring-shaped electrode 81 and the skin of the user, the light-shielding structure needs to be disposed to be staggered with respect to the first ring-shaped electrode 81, which results in a larger area of the bottom lens 221. In the embodiment of the present application, the first ring-shaped electrode 81 is disposed on the bottom lens 221 to achieve the light-blocking and monitoring functions, thereby reducing the area of the bottom lens 221.

In some examples, the material of the first ring electrode 81 may be a conductive ceramic. The material of the first ring electrode 81 may include a dark material, such as a black material, so that the first ring electrode 81 has a dark color as a whole. Therefore, the first ring-shaped electrode 81 can effectively block or absorb light, and is also beneficial to reducing the light reflectivity of the first ring-shaped electrode 81.

In some examples, fig. 7 schematically shows the structure of the first ring electrode 81 of an embodiment of the present application. Referring to fig. 7 and 8, the first ring electrode 81 may include an electrode body 811 and a light-shielding layer 812. The outer surface of the electrode body 811 is provided with a light-blocking layer 812. Illustratively, the light-blocking layer 812 covers the outer surface of the electrode body 811, i.e., the light-blocking layer 812 is disposed around the electrode body 811. The material of the electrode body 811 may be conductive ceramic or conductive metal. The light-blocking layer 812 is a conductive structure. The material of the light-blocking layer 812 may include a dark material, for example, a black material, so that the first ring-shaped electrode 81 has a dark appearance. Therefore, the first ring-shaped electrode 81 can effectively block or absorb light, and is also beneficial to reducing the light reflectivity of the first ring-shaped electrode 81.

In some realizable manners, referring to fig. 6, the outer surface of the bottom lens 221 facing away from the circuit board 30 has an annular recess 221a. The shape of the annular recess 221a matches the shape of the first annular electrode 81. At least a portion of the first ring-shaped electrode 81 is accommodated in the ring-shaped recess 221a. The first ring electrode 81 may be embedded in the bottom lens 221. The height of the first ring electrode 81 protruding the bottom lens 221 is small, which is beneficial to reducing the possibility that the first ring electrode 81 presses the skin of the user to cause the wearing comfort to be reduced. In some examples, the first ring electrode 81 is entirely received within the ring-shaped recess 221a. The outer surface of the first annular electrode 81 facing away from the circuit board 30 is flush with the outer surface of the bottom lens 221 facing away from the circuit board 30, so that the wearing comfort is improved. In some examples, the first ring electrode 81 and the ring-shaped recess 221a are both circular rings.

In some implementations, the cardiac monitor 80 also includes a connection post 82. The bottom lens 221 has an escape through hole 221b. The connecting column 82 is disposed in the avoiding through hole 221b. The connection post 82 electrically connects the first ring electrode 81 and the circuit board 30. The escape through hole 221b penetrates both surfaces of the bottom lens 221 in the thickness direction X. The connecting column 82 is inserted into the escape through hole 221b. The connection between the connecting post 82 and the bottom lens 221 can be sealed to prevent moisture from entering the housing 20.

In some examples, the connecting post 82 and the first ring electrode 81 may be a unitary structure.

In some examples, the bottom lens 221 includes an annular recess 221a. The escape through hole 221b penetrates the bottom wall of the annular recess 221a, so that the escape through hole 221b and the annular recess 221a communicate. The first ring electrode 81 covers the connection post 82 and the escape through hole 221b.

In some examples, a spring may be disposed on the circuit board 30. The connecting posts 82 press against the spring plate to make electrical connection with the circuit board 30.

In some examples, the first light-shielding member 50 is an electrically conductive member, i.e., the first light-shielding member 50 has both light-shielding and electrical conductivity properties. The connection post 82 is electrically connected to the circuit board 30 through the first light-blocking member 50. First light-proof piece 50 has the function of keeping out the light and realizes the function that first ring electrode 81 and circuit board 30 electricity are connected to need not set up first light-proof piece 50 and other conducting structure simultaneously between spliced pole 82 and the circuit board 30, be favorable to reducing spare part use quantity, reduce the assembly degree of difficulty of wearable equipment 10, also can save the inside installation space of shell 20.

Illustratively, the first light-shielding member 50 may be, but is not limited to, a circular ring shape. The connection post 82 is disposed corresponding to the first light-blocking member 50.

Illustratively, referring to fig. 5, the first light-blocking member 50 includes a first flexible conductive layer 51 and a first conductive adhesive layer 52. A first conductive adhesive layer 52 is arranged between the first flexible conductive layer 51 and the bottom lens 221. The first flexible conductive layer 51 and the bottom lens 221 are bonded, so that additional connecting structures such as screws, buckles or rivets are not required to be arranged between the first flexible conductive layer 51 and the bottom lens 221, and therefore, on one hand, the complexity of the connecting structure between the first flexible conductive layer 51 and the bottom lens 221 is reduced, and the assembly difficulty is reduced; on the other hand, it is not necessary to provide corresponding connection structures, such as holes, on the first flexible conductive layer 51 and the bottom lens 221, which is beneficial to reducing the processing difficulty of the first flexible conductive layer 51 and the bottom lens 221, and ensures that the first flexible conductive layer 51 and the bottom lens 221 have good structural integrity.

A first conductive adhesive layer 52 is disposed between the first flexible conductive layer 51 and the circuit board 30. The first flexible conductive layer 51 and the circuit board 30 are bonded, so that additional connecting structures such as screws, buckles or rivets are not required to be arranged between the first flexible conductive layer 51 and the circuit board 30, and therefore, on one hand, the complexity of the connecting structure between the first flexible conductive layer 51 and the circuit board 30 is favorably reduced, and the assembly difficulty is reduced; on the other hand, it is not necessary to provide corresponding connection structures, such as holes, on the first flexible conductive layer 51 and the circuit board 30, which is beneficial to reducing the processing difficulty of the first flexible conductive layer 51 and the circuit board 30 and ensures that the first flexible conductive layer 51 and the circuit board 30 have good structural integrity.

Illustratively, the first flexible conductive layer 51 is a conductive foam that can block light. The first conductive adhesive layer 52 is a conductive paste that can block light.

In some implementations, referring to fig. 4 and 5, the electrocardiac monitor 80 further includes a second ring electrode 83. The second ring electrode 83 is disposed on the bottom lens 221. The first ring electrode 81 is located inside the second ring electrode 83. The first ring electrode 81 and the second ring electrode 83 have a gap therebetween, that is, the first ring electrode 81 and the second ring electrode 83 are spaced apart from each other without contacting each other. The second ring electrode 83 is intended to be in contact with the skin of the user. The first ring electrode 81 is used for collecting human body bioelectricity signals, and the second ring electrode 83 is used for emitting electric signals to human body skin to eliminate environmental noise, thereby ensuring the accuracy of data collection by the first ring electrode 81.

Referring to FIG. 4, the ECG monitor 80 further includes finger electrodes 84. The finger electrodes 84 are electrically connected to the circuit board 30. The first ring electrode 81, the second ring electrode 83 and the finger electrode 84 may be used together for acquiring electrocardiogram related electrical signals. The finger electrodes 84 may be disposed on the sides of the housing 20 such that the user may view the finger electrodes 84. The finger of the user may touch the finger electrode 84, thereby inputting an electrical signal.

Fig. 9 schematically shows a partially exploded structure of the wearable device 10 according to an embodiment of the present application. Referring to fig. 5 and 9, the electrical connection 832 is located on a side of the bottom lens 221 facing the circuit board 30. The electrical connection portion 832 connects the second ring-shaped electrode 83 and the circuit board 30.

Illustratively, the skin-contacting portion 831 may be, but is not limited to, a circular ring shape, so that the circular skin-contacting portion 831 may be beneficial to improve the aesthetic sense of the wearable device 10 and improve the user satisfaction. The skin contact portion 831 and the first ring electrode 81 may be concentrically disposed. Electrical connection 832 may be a circular arc segment. The electrical connection portion 832 and the first ring electrode 81 may be concentrically disposed.

For example, the second annular electrode 83 may be formed on the surface of the bottom lens 221 by a plating process, so that the second annular electrode 83 has a small thickness and occupies a small space.

Because the second ring-shaped electrode 83 is of a ring-shaped structure, the contact area with the skin of the user can be increased, and different areas on the second ring-shaped electrode 83 can be in contact with the skin of the user, so that the second ring-shaped electrode 83 is not easy to be completely separated from the contact state with the skin of the user in the process that the user touches the wearable device 10 or uses the wearable device 10, but a part or the whole of the second ring-shaped electrode 83 always keeps in the contact state with the skin of the user, thereby reducing the possibility that the accuracy of data acquisition of the electrocardiogram monitor 80 is reduced and the generated electrocardiogram is distorted due to the complete separation of the second ring-shaped electrode 83 from the contact state with the skin of the user.

In some realizable forms, the second ring electrode 83 is a light-blocking structure. The second ring-shaped electrode 83 can effectively block light or absorb light.

In some examples, the material of the second ring electrode 83 may include a dark material, such as a black material, so that the second ring electrode 83 is dark overall.

In some examples, the second ring-shaped electrode 83 covers the outer circumferential surface of the bottom lens 221, which is advantageous for further reducing the possibility that external light is incident on the light receiving element 42 from the outer circumferential surface of the bottom lens 221.

In some realizable approaches, as shown in fig. 5 and 6, the bottom lens 221 includes a first light-transmissive portion 2211 and a second light-transmissive portion 2212.

In some examples, the second light-shielding member 100 is an electrically conductive member. The electrical connection portion 832 of the second ring-shaped electrode 83 is electrically connected to the circuit board 30 through the second light-shielding member 100. The second light-shielding member 100 has a light-shielding function and a function of electrically connecting the second annular electrode 83 to the circuit board 30, so that the second light-shielding member 100 and other conductive structures do not need to be arranged between the electrical connection portion 832 and the circuit board 30, the number of used parts is reduced, the assembly difficulty of the wearable device 10 is reduced, and the installation space inside the housing 20 can be saved.
