Abstract

A wrist watch charging assembly is provided. The wrist watch charging assembly may include a charging cord, a charging port connector and a charging head that are electrically connected to two ends of the charging cord, and a mobile pin electrically connected to a circuit board inside the watch case, wherein the charging cord is fixed relative to the watch band, and the charging head is attached onto the watch case by means of magnetic adhesion to be in electrical contact with the mobile pin. A wrist watch that has an integrated wrist watch charging assembly is also provided. The end of the charging head for connecting the mobile pin is optionally snapped into a holding groove on the watch band, and the charging port for external connection is optionally snapped into a charging port cap on the watch band.

First claim

The invention claimed is:

1. A charging assembly for a wrist watch, the charging assembly comprising:
a charging cord encapsulated in a watch band configured to connect to a watch case of the wrist watch;
a charging port connector electrically connected to a first end of the charging cord;
a charging head electrically connected to a second end of the charging cord by an extension portion, the charging head and the extension portion being removably retained in a groove formed in the watch band when the charging head is not in use, and the charging head and the extension portion being located in a charging position exterior of the groove when charging the wrist watch, wherein, when the charging head is in the charging position, the charging head is configured to secure to a watch cover of the wrist watch by at least one magnet attached to the watch cover, the watch cover attaching to the watch case; and
a mobile pin electrically connected to a circuit board inside the watch case, the mobile pin being in electrical connection with the charging head when the charging head is in the charging position.

2. The wrist watch charging assembly of claim 1 , wherein the charging cord and the watch band are integrally injection-molded.

3. The wrist watch charging assembly of claim 1 , wherein a free end of the watch band is integrally connected with a charging port cap for holding the charging port connector, and wherein the charging port cap is rotatably disposed relative to a main part of the watch band.

4. The wrist watch charging assembly of claim 3 , wherein a magnet is provided on the watch case at a position close to the watch band, and wherein the charging head comprises a metal part for engagement with the magnet and a contact for contacting the mobile pin.

5. The wrist watch charging assembly of claim 1 , wherein a free end of the watch band is pivotally connected with a charging port cap for holding the charging port connector.

6. The wrist watch charging assembly of claim 1 , wherein the at least one magnet is provided on the watch cover at a position close to the watch band, and the charging head comprises a metal part for engagement with the at least one magnet and a contact for contacting the mobile pin.

7. The wrist watch charging assembly of claim 6 , wherein the at least one magnet comprises two magnets and the mobile pin is disposed between the two magnets.

8. The wrist watch charging assembly of claim 1 , wherein the at least one magnet is provided on the watch case at a position close to the watch band, and wherein the charging head comprises a metal part for engagement with the at least one magnet and a contact for contacting the mobile pin.

9. A wrist watch, comprising:
a watch case;
a circuit board inside the watch case;
a watch band connected to the watch case;
a watch cover connected to the watch case; and
a wrist watch charging assembly comprising:
a charging cord encapsulated in a watch band of the wrist watch;
a charging port connector electrically connected to a first end of the charging cord;
a charging head electrically connected to a second end of the charging cord by an extension portion, the charging head and the extension portion being removably retained in a groove formed in the watch band when the charging head is not in use, and the charging head and the extension portion being located in a charging position exterior of the groove when charging the wrist watch, wherein, when the charging head is in the charging position, the charging head is secured to the watch cover by at least one magnet attached to the watch cover; and
a mobile pin electrically connected to the circuit board, the mobile pin being in electrical connection with the charging head when the charging head is in the charging position.

10. The wrist watch of claim 9 , wherein the watch band is rotatably connected to the watch case.

11. The wrist watch of claim 9 , wherein the charging cord and the watch band are integrally injection-molded.

12. The wrist watch of claim 9 , wherein a free end of the watch band is integrally connected with a charging port cap for holding the charging port connector, and wherein the charging port cap is rotatably disposed relative to a main part of the watch band.

13. The wrist watch of claim 9 , wherein a free end of the watch band pivotally connected with a charging port cap for holding the charging port connector.

14. The wrist watch of claim 9 , wherein the at least one magnet is provided on the watch cover at a position close to the watch band, and the charging head comprises a metal part for engagement with the at least one magnet and a contact for contacting the mobile pin.

15. The wrist watch of claim 14 , wherein the at least one magnet comprises two magnets and the mobile pin is disposed between the two magnets.

16. A wrist watch comprising:
a watch case;
a circuit board inside the watch case;
a watch band connected to the watch case;
a watch cover connected to the watch case; and
a wrist watch charging assembly comprising:
a charging cord encapsulated in a watch band of the wrist watch;
a charging port connector electrically connected to a first end of the charging cord;
a charging head electrically connected to a second end of the charging cord by an extension portion, the charging head and the extension portion being removably snap-fit into in a groove formed in the watch band when the charging head is not in use, and the charging head and the extension portion being located in a charging position exterior of the groove when charging the wrist watch, wherein, when the charging head is in the charging position, the charging head is secured to the watch cover by at least one magnet attached to the watch cover; and
a mobile pin electrically connected to the circuit board, the mobile pin being in electrical connection with the charging head when the charging head is in the charging position.
