Specifically, referring to fig. 10, the main body 100 includes a spring piece 160 electrically connected to the circuit board 140, and the spring piece 160 is electrically connected to the connection terminal 150. In some embodiments, the main body 100 further includes a sleeve 170 and an elastic member 180, the sleeve 170 is made of metal, the sleeve 170 is provided with a cavity 171 to cover the connection terminal 150 and the elastic member 180, one end of the elastic member 180 abuts against the sleeve 170, the other end of the elastic member 180 abuts against the connection terminal 150, and the elastic piece 160 abuts against the sleeve 170 and is electrically connected to the connection terminal 150 through the sleeve 170 or the elastic member 180. In some embodiments, the elastic member 180 may be a spring structure or a leaf spring structure and made of a metal material, and in such embodiments, the elastic member 180 may be used to electrically connect the circuit board 140 and the connection terminal 150. In other embodiments, the elastic member 180 may be an elastic column structure and may be made of a non-metal material, and the elastic piece 160 may be electrically connected to the connection terminal 150 through the sleeve 170. The elastic member 180 and the sleeve 170 are disposed to facilitate the assembly of the connection terminal 150 and the housing 110, and to enable the circuit board 140 to be electrically connected to the connection terminal 150 relatively easily, and the elastic member 180 may further accumulate an elastic force so that the connection terminal 150 can press against the circuit structure of the strap 200, thereby ensuring the reliability of the electrical connection between the connection terminal 150 and the circuit structure of the strap 200.

Further, in some embodiments, the elastic sheet 160 includes a supporting portion 161, a connecting portion 163, and a bending portion 165 connected between the supporting portion 161 and the connecting portion 163, the connecting portion 163 is electrically connected to the circuit board 140, and the bending portion 165 accumulates elastic potential energy to make the supporting portion 161 tightly support the sleeve 170. The arrangement can ensure the contact reliability of the elastic sheet 160 and the sleeve 170, and further ensure the electric connection reliability of the elastic sheet 160 and the sleeve 170. Further, the connection terminal 150 includes a body 151 and a boss 153 integrally formed on the circumference of the body 151, the elastic member 180 abuts against the boss 153, the sleeve 170 is provided with an opening 173 communicated with the cavity 171, the body 151 extends out of the cavity 171 from the opening 173, the boss 153 is accommodated in the cavity 171, and the width of the boss 153 is greater than that of the opening 173. This arrangement prevents the connection terminal 150 from easily coming out of the sleeve 170, and in some embodiments, the sleeve 170 and the connection terminal 150 can be electrically connected by the contact between the boss 153 and the sleeve 170. Further, a sealing ring may be disposed on an outer circumference of the sleeve 170 to seal a gap between the sleeve 170 and the housing 110, so as to improve waterproof and dustproof performance of the body 100. Further, the sleeve 170 may be closed at an end abutting against the elastic sheet 160, so as to isolate the slot 103 from the installation cavity 101 of the housing 110 through the sleeve 170, thereby improving the waterproof and dustproof performance of the main body 100. It is understood that the sleeve 170 and the elastic member 180 are not required, and the connection terminal 150 may be directly electrically connected to the resilient member 160 or may be electrically connected to the circuit board 140 by other structures.

In the wearable device 10, since the band body 210 of the strap 200 is provided with the charging terminal 220, and the charging terminal 220 is electrically connected to the circuit board 140 of the main body 100 through the connection terminal 150, the battery in the main body 100 can be charged through the charging terminal 220 and the connection terminal 150, so that a relatively high charging efficiency can be obtained through wired charging. Since the charging terminal 220 is disposed on the band body 210 of the band 200, the main body 100 of the wearable device 10 does not need to be provided with an exposed metal contact for charging or data transmission, and when the band 200 is mounted on the card slot 103, the main body 100 has high appearance integrity, so that the wearable device 10 has good appearance characteristics. Because the charging terminal 220 is disposed on the strap 200, the corresponding charging circuit can be moved to the strap 200, so that the installation space inside the main body 100 can be saved, the saved installation space can be used for installing a battery with larger capacity, the cruising performance of the wearable device 10 can be improved, and the saved installation space can be omitted, thereby facilitating the light and thin design of the main body 100. Since the charging terminal 220 is shielded by the band body 210 in the thickness direction of the band 200, the charging terminal 220 can be prevented from easily contacting the skin or moisture and dust in the environment or easily colliding with other objects, and the like, so that the charging terminal 220 can be prevented from being easily corroded to cause poor electrical contact, and the charging terminal 220 can be prevented from being easily collided to cause scratches or damage. The structure in which charging terminal 220 is shielded by band body 210 in the thickness direction of band 200 can also avoid a large influence on the appearance characteristics of band 200, for example, charging terminal 220 is not easily visually observed when band 200 wears main body 100 to the wrist of the user, and thus the appearance characteristics of band 200 can be maintained.

Further, referring to fig. 11 and 12, the band body 210 includes a first surface 211 and a second surface 213 disposed opposite to each other, and a side circumferential surface 215 between the first surface 211 and the second surface 213, the first surface 211 faces the wrist of the user when the band 200 is worn on the main body 100 to the wrist of the user, and the charging terminal 220 is exposed from the side circumferential surface 215. Further, the side circumferential surface 215 is provided with an insertion hole 201, and the charging terminal 220 is exposed from the insertion hole 201 and spaced apart from the end of the strap body 210. This arrangement can further hide the charging terminals 220 to provide better protection to the charging terminals 220 and prevent the charging terminals 220 from having a large influence on the appearance of the strap 200.

Further, the strap 200 includes a fastener 230 electrically connected to the connection terminal 150 and the charging terminal 220, and the fastener 230 is disposed at an end of the strap 210 away from the charging terminal 220 and is limited to the slot 103. In some embodiments, the engaging member 230 is substantially cylindrical and protrudes out of the end of the strap 210 far from the charging terminal 220, and the engaging member 230 can cooperate with the locking structure of the main body 100, so that the strap 200 can be reliably retained in the slot 103 and the strap 200 can be prevented from being easily removed from the housing 110. The engaging member 230 is made of a metal material and can be electrically connected to the charging terminal 220 and the connecting terminal 150. In some embodiments, strap 200 includes a flexible circuit board 240 disposed on strap 210, where flexible circuit board 240 electrically connects fastening element 230 and charging terminal 220, and flexible circuit board 240 is hidden in strap 210. The flexible circuit board 240 has a good deformation property, can bend along with the tape body 210, and can ensure the reliability of the electrical connection between the charging terminal 220 and the engaging member 230. The flexible wiring board 240 has a relatively thin thickness, and thus the thickness of the strap 200 can be prevented from being increased too much. For example, in some embodiments, the band 200 is divided into two parts in the thickness direction of the band 200 before processing and molding, and after the engaging member 230, the flexible circuit board 240 and the charging terminal 220 are mounted on one part, the other part is attached and fixedly connected to form a reliable connection. The arrangement that the flexible circuit board 240 is hidden in the tape body 210 can also play a good role in protecting the flexible circuit board 240, prevent the flexible circuit board 240 from being damaged or corroded, and realize a good sealing design.

Further, the binding band 200 includes a magnetic member disposed at the end of the band body 210, and the magnetic member and the charging terminal 220 are disposed at the same end of the band body 210. The magnetic attraction piece is designed to be a magnet and is close to the charging terminal 220, the magnet or a magnetic metal piece can be arranged near the plug of the charger, or the plug of the charger can be made of the magnetic metal piece, and the magnetic metal piece can be iron, cobalt, nickel and alloys thereof. When the plug of the charger is inserted from the jack 201 of the belt body 210, the magnetic attraction piece can attract the charger, so that the plug of the charger can be butted and fastened with the charging terminal 220, and the reliability of electric connection is ensured.

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.
