A smart watch includes a watch strap and a flexible display panel. The first end of the flexible display panel is attached to the watch strap, and the second end of the flexible display panel is a free end. The flexible display panel has a bent state and a flattened state. When the flexible display panel is in the bent state, the flexible display panel and the watch strap are bent together and the flexible display panel is located on and in contact with an outer surface of the watch strap. When the flexible display panel is in the flattened state, the second end of the flexible display panel is out of contact with the outer surface of the watch strap and the flexible display panel is flattened in the same plane.

The present disclosure relates to a smart watch including a watch dial. The smart watch further include: a battery provided in a watch frame of the watch dial to supply electric power to a circuit in the watch dial. According to the present disclosure, by providing batteries in the watch frame and the watchband of the smart watch, spaces occupied by the watch frame and the watchband may be sufficiently utilized to increase total electricity storage capacity of the smart watch such that the smart watch has a prolonged standby time.

According to example embodiments, charging of a wireless device includes using a time-displaying power source system to transmit electrical power to a wireless receiver by inductive electrical power transfer.

An electrically controlled mechanical watch includes a mainspring, a speed regulator that controls a rotation cycle of a wheel train, a control unit that controls the speed regulator, a power generator, a first power accumulation device, a second power accumulation device that is coupled to the first power accumulation device in parallel via a switch, and a detection unit that detects a mechanical energy amount accumulated in the mainspring. In a case in which the switch is in an off state, when it is detected that the mechanical energy amount exceeds a first set value, the control unit controls the switch from the off state to an on state. In a case in which the switch is in the on state, when it is detected that the mechanical energy amount falls below a second set value, the control unit controls the switch from the on state to the off state.

A novel wireless charger comprises a charger bracket provided with a first charging module; a mobile phone charging panel provided with a second charging module; a watch charging panel provided with a third charging module; a base provided with a power jack; wherein, the base is provided with an electric slip ring, a gear is sleeved on the electric slip ring, and a clamping pin abutting against the gear is also arranged in the base; the charging method is as follows: a wirelessly-charged mobile phone is placed on the mobile phone charging panel, a wirelessly-charged watch is placed on the watch charging panel, and a wirelessly-charged earphone is placed on the charger bracket.

A wearable power supply includes a strap to be worn on a user's wrist, arm, waist, leg or head; a flexible secondary battery carried by the strap; and a connector slot disposed on the strap and electrically connected to the flexible secondary battery, wherein the flexible secondary battery is capable of supplying current to a mobile device via a connecting wire connected between the connector slot and the mobile device, and is recharged from an external power supply connected to the connector slot. When the wearable power supply takes the form of a wristband, it can be used as a carrier of a hand worn mobile device, such as a smart watch or a smart bracelet, to provide a longer operating range.

A wearable electronic device includes a host, a wearing member, and a backup power module. The host includes a functional module, a main power module, and an electrical connection port. The main power module is configured to supply power to the functional module. The electrical connection port is electrically connected to the main power module. The wearing member is connected to the host. The backup power module is detachably disposed at an upper region or a surrounding region of the host to electrically couple the electrical connection port, or is detachably disposed on the wearing member and configured to electrically couple the electrical connection port to supply power to the main power module.
