Portable electronic device capable of preventing display from falling

Abstract

The invention discloses a portable electronic device capable of preventing a display from falling. The portable electronic device utilizes a control unit for controlling a power unit to provide electricity for an electromagnetic component to generate a first active magnetic property for magnetically repulsing or magnetically attracting a moving magnetic component with a first magnetic property, soas to drive the moving magnetic component to move to a first position when the control unit determines an included angle between a first module and a second module is greater than a predetermined angle. When the moving magnetic component is located at the first position, a pivoting mechanism disposed between a supporting frame and the second module drives the supporting frame to pivotally unfoldrelative to the second module, so as to support the second module on a supporting surface, which prevents the second module from falling.

Description

technical field [0001] The invention relates to a portable electronic device, in particular to a portable electronic device which has a relatively pivotable screen and a keyboard and can prevent the screen from toppling due to an excessive opening angle. Background technique [0002] Nowadays, the tablet computer can usually be equipped with an extended keyboard dock, so that it can be tilted like a notebook computer when needed and provide a physical keyboard for convenient input operations. The tablet computer and the expanded keyboard dock are usually detachably combined by plugging the jack or connector on the side of the tablet computer body with the post or the corresponding connector of the expanded keyboard dock. There are also some tablet computers that are detachably combined with the expanded keyboard base through the magnetic attraction elements on the side of the fuselage attracting the magnetic attraction elements of the expanded keyboard base. However, becaus...

Problems solved by technology

However, when the user is operating the support structure, since the support structure is arranged on the back side of the tablet computer, the user cannot correctly grasp the position of the support structure, so the operation is more inconvenient; moreover, in order to facilitate the user to store and take out the support structure , the back side of the tablet computer is usually provided with auxiliary structures such as grooves for finger insertion or latch devices adjacent to the support structure, which also affects the overall integrity and aesthetics of the backside of the tablet computer
