Referring to fig. 3, the strap 200 includes a strap body 210 and a conductive layer 220 disposed on a surface of the strap body 210, the strap body 210 may be made of a polymer material, such as plastic, silicone, rubber, or leather, and the strap body 210 has a certain flexibility, so that the strap body 210 can be bent and deformed to be close to the skin of the user during the wearing process of the wearable device 10. The conductive layer 220 is a metal plating layer, for example, the conductive layer 220 may be formed on the surface of the tape body 210 by an electroplating process, and the conductive layer 220 may also be formed on the surface of the tape body 210 by a printing, coating, or other processes. One end of the belt 210 is fixedly connected to the electronic device 100, and the conductive layer 220 is electrically connected to the ecg sensor. After the electronic device 100 is worn in one hand of the user to attach the conductive layer 220 to the skin of the user, the other hand of the user can attach the detection electrode, so that the detection electrode, the electrocardiogram sensor, the conductive layer 220 and the body of the user form a detection loop, and the electrocardiogram data of the user can be acquired. Of course, in other embodiments, the electronic device 100 may be worn on other parts of the user's body, such as the feet or the head, to make the conductive layer 220 conductive with the user's body, and when the user touches the detection electrode through other parts of the body, the detection electrode, the electrocardiogram sensor, the conductive layer 220 and the user's body can form a detection loop to acquire electrocardiogram data of the user.

Specifically, in some embodiments, the band 210 includes a first side 211 and a second side 213 that are opposite, and when the electronic device 100 is worn on the arm of the user, the second side 213 faces the skin of the user, and the conductive layer 220 covers part or all of the second side 213. For example, the conductive layer 220 may cover a partial region of the second side 213, and the conductive layer 220 may also cover the entire second side 213. Since the tape body 210 has a relatively large surface area, the conductive layer 220 may also be provided to have a relatively large surface area, so that the conductive layer 220 can be brought into more reliable contact with the skin of the user, to ensure reliability of electrical contact, and to maintain stability of signal transmission during electrocardiographic measurement. Further, an electrical connector, such as a wire, a coaxial line, etc., may be disposed inside the band 210, and the electrical connector is electrically connected to the conductive layer 220, and the electrical connector extends to the end of the band 210 and is electrically connected to the electronic device 100, so as to be electrically connected to the ecg sensor.

In other embodiments, the conductive layer 220 covers the entire outer surface of the tape 210, and the conductive layer 220 at the end of the tape 210 is in contact with and conductive with the electronic device 100. In such an embodiment, conductive layer 220 is easier to machine. For example, the tape body 210 may be entirely immersed in the electrolyte solution, and the entire surface of the tape body 210 may be metallized. As another example, other processes may be used to form the conductive layer 220 on the entire outer surface of the tape body 210.

In the strap 200, since the conductive layer 220 is disposed on the surface of the strap body 210, and the conductive layer 220 is electrically connected to the ecg sensor, after the electronic device 100 is worn on one hand of the user to make the conductive layer 220 fit to the skin of the user, the other hand of the user can fit to the detection electrode, so that the detection electrode, the ecg sensor, the conductive layer 220 and the body of the user form a detection loop to obtain the ecg data of the user. Since the strap 200 has a relatively large surface area, the conductive layer 220 can form a relatively large contact area for the skin of the user, thereby ensuring the reliability of the electrical contact to facilitate the electrocardiograph sensor to acquire more accurate data.

Further, in some embodiments, the wearable device 10 includes another strap, the strap 200 and the other strap are respectively connected to the opposite ends of the electronic device 100, and the other strap includes a driving electrode electrically connected to the ecg sensor. In the process of measuring the electrocardiogram of the user by the electronic device 100, the driving electrodes are conducted with the body of the user to serve as a ground reference. The structure of the other band may be similar to that of the band 200, for example, the other band may also include a band body 210 and a conductive layer 220, and the conductive layer 220 may be used as a driving electrode so that the driving electrode can be reliably attached to the body of the user. The drive electrode can enhance the anti-interference capability of the electrocardiogram detection loop so as to improve the reliability of electrocardiogram measurement. Of course, in other embodiments, the driving electrode may be disposed on the back side of the electronic device 100 and be in conduction with the body of the user when the electronic device 100 is worn on the body of the user. Of course, the driving electrode may have other structural forms, for example, the driving electrode may be a metal patch structure.

In some embodiments, the elastic member 145 may be a spring structure or a spring plate structure and made of a metal material, and in such embodiments, the elastic member 145 may be used to electrically connect the circuit board 120 and the connection terminal 147. In other embodiments, the elastic member 145 may be an elastic column structure and may be made of a non-metal material, and the elastic piece 141 may be electrically connected to the connection terminal 147 through the sleeve 143. The elastic member 145 and the sleeve 143 are disposed to facilitate the assembly of the connection terminal 147 and the middle frame 111, and to enable the circuit board 120 to be electrically connected to the connection terminal 147 relatively easily, and the elastic member 145 may further accumulate an elastic force so that the connection terminal 147 may press the conductive layer 220 of the strap 200 or the electrical connector, thereby ensuring the reliability of the electrical connection between the connection terminal 147 and the conductive layer 220 of the strap 200.

Further, in some embodiments, the elastic piece 141 includes a supporting portion 141a, a connecting portion 141b, and a bending portion 141c connected between the supporting portion 141a and the connecting portion 141b, the connecting portion 141b is electrically connected to the circuit board 120, and the bending portion 141c accumulates elastic potential energy to enable the supporting portion 141a to support the sleeve 143.

Further, referring to fig. 5, the connection terminal 147 includes a body 147a and a boss 147b integrally formed in a circumferential direction of the body 147a, the elastic member 145 abuts against the boss 147b, the sleeve 143 is provided with an opening 144 communicating with the cavity 142, the body 147a extends out of the cavity 142 from the opening 144, the boss 147b is accommodated in the cavity 142, and a width of the boss 147b is greater than a width of the opening 144. This arrangement prevents the connection terminal 147 from being easily removed from the sleeve 143. In some embodiments, the sleeve 143 and the connection terminal 147 may be electrically connected by the contact between the boss 147b and the sleeve 143. Further, a sealing ring may be disposed on the outer periphery of the sleeve 143 to seal a gap between the sleeve 143 and the middle frame 111, so as to improve the waterproof and dustproof performance of the electronic device 100.
