A wireless charging stand is used to position a handheld electronic device and contains: a body, a wireless charging transmitter, a rotary head, a body, and a bluetooth mechanism accommodated in the body. The body includes an upper segment axially connected with the rotary head which universally rotates on the upper segment and couples with and removes from the handheld electronic device. The wireless charging transmitter is accommodated in or on the body to wirelessly charge power to the handheld electronic device. The bluetooth mechanism includes a bluetooth module, a speaker, and a first power component for supplying the power. The speaker and the first power component are electrically connected with the bluetooth module, the bluetooth module receives audio information of the handheld electronic device and plays the audio information by ways of the speaker, and the first power component is also electrically connected with the wireless charging transmitter.

The present invention relates to a wireless charging stand which has bluetooth and wireless charging functions.
A handheld electronic device, such as a mobile phone, is manually held by a user and is charged power by using a charger, a cable or a mobile power, so the handheld electronic device is charged the power within a limited range of a power source.
To overcome above-mentioned problem, a wireless charger is developed and contains a wireless charging transmitter and a wireless charging receiver, wherein the wireless charging transmitter has a first circuit board with a first coil, and the wireless charging receiver has a second circuit board with a second coil, such that a magnetic field forms on the first coil and acts on the second coil, thus resulting electromagnetic induction. Thereafter, the second coil generates inducing current to charge the power to the handheld electronic device.
FIG. 1 is a perspective view of the assembly of a wireless charging stand according to a first embodiment of the present invention.
FIG. 2 is another perspective view of the assembly of the wireless charging stand according to the first embodiment of the present invention.
FIG. 3 is a perspective view of the operation of the wireless charging stand according to the first embodiment of the present invention.
FIGS. 1 and 2, a wireless charging stand 100 according to a first embodiment of the present invention comprises: a body 10, a rotary head 20, and a bluetooth mechanism (not shown) accommodated in the body 10. The wireless charging stand 100 also comprises a wireless charging transmitter 40 (as shown in FIG. 8). The body 10 includes an upper segment 11 axially connected with the rotary head 20 which universally rotates on the upper segment 11 and couples with and removes from a handheld electronic device. The wireless charging transmitter 40 is accommodated in or on the body 10 to wirelessly charge power to the handheld electronic device, wherein the bluetooth mechanism includes a bluetooth module, a speaker, and a first power component for supplying the power. The speaker and the first power component are electrically connected with the bluetooth module, and the bluetooth module receives audio information of the handheld electronic device and plays the audio information by ways of the speaker. The first power component is also electrically connected with the wireless charging transmitter 40.
Preferably, the bluetooth mechanism also includes a receiver electrically connected with the bluetooth module to receive exterior sounds, and the exterior sounds are transmitted to the handheld electronic device via the bluetooth module.
The bluetooth mechanism further includes a volume control button electrically coupled with the speaker to adjust volumes of the speaker.
