Gravity center adjustable device, and gravity center self-adjusting device and electronic device using the same

A gravity center self-adjusting device comprising:

• a gravity sensor;
• a processor connected with the gravity sensor;
• and
• a gravity center adjustable device connected with the processor, the gravity center adjustable device comprising:
• a driving member comprising a driving main body, two transmission shafts, and two gear wheels, each one of the two transmission shafts comprises a first end secured to the driving main body, and a second end opposite to the first end, each one of the two gear wheels is coiled around the second end of one of the two transmission shafts;
• and
• two gravity center adjusting members, each one of the two gravity center adjusting members comprises a gravity center adjusting shaft, and two weight balls secured to two opposite ends of the gravity center adjusting shaft respectively;
• wherein the gravity center adjusting shaft comprises a rack shaft, teeth of the rack shaft are engaged with those of one of the two gear wheels, thereby when the one of the two gear wheels rotates, the rack shaft will move around along its own axial relative to the one of the two gear wheels;
• wherein the processor is connected with the driving member, gravity sensor is configured to sense whether the gravity center self-adjusting device has a gravity acceleration, and send the information of whether the gravity center self-adjusting device has a gravity acceleration to the processor, the processor is configured to receive the information of whether the gravity center self-adjusting device has a gravity acceleration from the gravity sensor, and processes the information, until the processor receives an information that the gravity center self-adjusting device has a gravity acceleration, the processor does not start the driving member, when the processor receives an information that the gravity center self-adjusting device has a gravity acceleration, the processor starts the driving member, and the driving member drives the two gravity center adjusting members to adjust the gravity center of the gravity center self-adjusting device.
