Abstract: A pivot structure includes a gear mechanism, a first pivot assembly including a first stand, and a second pivot assembly including a second stand. The gear mechanism includes a first gear having a tooth portion, transmitting gears, and an end gear. The first gear, the transmitting gears, and the end gear are engaged in sequence. The second stand is rotated between a closed angle and an opening angle relative to the first stand by the gear mechanism. The tooth portion drives the transmitting gears to rotate the end gear when the second stand is rotated between a first middle angle and a second middle angle relative to the first stand, and the tooth portion is departed from the first transmitting gear when the second stand is rotated between the closed angle and the first middle angle relative to the first stand.

Abstract: A collapsible electronic equipment includes a pivot structure, a base and a cover. The pivot structure includes a first pivot assembly, a second pivot assembly, and a gear mechanism. The first pivot assembly is disposed on a side of the base. The second pivot assembly is disposed on a side of the cover. The gear mechanism is connected to the first pivot assembly and the second pivot assembly. The cover may be opened or closed relative to the base by the gear mechanism. When the cover is opened at 180 degrees relative to the base, the gap between the cover and the base is narrow, and the surfaces of the cover and the base are located on the same plane.
