In the middle of the carrier 431 is defined a recess 435 having a window hole 436 facing the sensor 413. When the body 410 is embedded in the recess 435 and fixed to the carrier 431, the connector 433 will be connected to the connecting port 412 simultaneously, allowing the first battery 411 to absorb the electric power from the second battery 432.

Referring to FIG. 5A, a wearable electronic device 500 in accordance with a fifth embodiment of the present invention comprises a body 510, a strap 520 and a plug-in power supply 530. The body 510 is provided with a first battery 511, a connecting port 512 electrically connected to the first battery 511 and a sensor 513. Both ends of the strap 520 are provided with a mechanism that can be combined with each other, and are connected to the body 510, so as to wear the body 510 on a wearers wrist. The plug-in power supply 530 is provided with a carrier 531, at least one second battery 532 disposed in the carrier 531, and a connector 533 disposed in the carrier 531 and electrically connected to the second battery 532. The plug-in power supply 530 is worn on a wearers wrist through the carrier 531 and kept on one side of the body 510, so that when the connector 533 is connected to the connecting port 512, the electric power of the second battery 532 is transmitted to the first battery 511. The strap 520 and the carder 531 can also be formed as the above-mentioned carder 331/331a/431.

For the wearable electronic device 100/200/300/300a/400/500 disclosed in the above embodiments, the first battery 111/211/311/411/511 absorbs the electric power from the second battery 132/232/3321432/532 by connecting the connector 133/233/333/433/533 to the connecting port 112/212/312/412/512. The connector 133/233/333/433/533 and the connecting port 112/212/312/412/512 may be any type of transmission interface, unrestricted by a specific interface.

The present invention may also transmit the electric power by an inductive charging mode. That is, in some embodiments of the present invention, as shown in FIGS. 1B/2B/3B/3D/4B/5B, the body 110/210/310/410/510a may carry a first induction coil 114/214/314/414/514 to replace the connecting port 112/212/312/412/512, the plug-in power supply 130/230/330/330a/430/530a may utilize a second induction coil 138/238/338/438/538 to replace the connector 133/233/333/433/533. Thus, the second induction coil 138/238/338/438/538 will generate a magnetic field around it as the current flows through it, which generates an induction current on the first induction coil 114/214/314/414/514 through electromagnetic induction that is directed to the first battery 111/211/311/411/511, thereby achieving the inductive charging effect to supplement the electric power consumed by the first battery 111/211/311/411/511. It should be noted that the wearable electronic device 100/200/300/300a/400 will not have both contact charging and inductive charging modes, and the two charging modes will be implemented separately. However, in order to reduce the number of figures, the two charging modes are Illustrated in FIGS. 1B/2B/3B/3D/4B simultaneously. The second induction coil 138/238/338/438/538 may also receive a current from a wireless charger (not shown), so as to supplement the electric power consumed by the second battery 132/232/332/432/532. In the embodiment of FIG. 5A or 5B, since the plug-in power supply 530 or 530a, and the strap 520 are worn on a wearer's wrist parallelly, the connector 533 or the second induction coil 538 must extend outside the carrier 531 via a connecting line 534 to facilitate coupling to the connecting port 512 or the first induction coil 514. For simplification, the parts of FIG. 5B that are the same as those of FIG. 5A are marked with the same symbols, and previous description of FIG. 5A also applies to FIG. 5B and will not be repeated.

Since the acceptable battery size, quantity and weight of the plug-in power supply 130/230/330/300a/430/530/530a are less limited, the high battery capacity and strong endurance can meet the needs of a large or long time of use.

It should be noted that when the plug-in power supply 130/230/330/300a/430/530/530a is described as an independent claim, the description of the first battery 111/211/311/411/511 and the first induction coil 114/214/314/414/514 will omit the term “first”, only shown as the battery and the induction con, respectively.

While we have shown and described various embodiments in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
