BIAXIAL PIVOT MECHANISM AND PORTABLE ELECTRONIC DEVICE THEREOF

摘要

A biaxial pivoting mechanism for rotating a first casing relative to a second casing is disclosed in the present disclosure. The biaxial pivoting mechanism includes at least one fixing component, a first shaft, a first main gear, a second shaft, a second main gear and a transmission gear set. The fixing component includes a first area and a second area. The first shaft and the second shaft are disposed on the first area and the second area and further connected to the first casing and the second casing respectively. The first main gear and the second main gear are respectively disposed on the first shaft and the second shaft. The transmission gear set is engaged with the first main gear and the second main gear. As the first main gear rotates at a first direction, the second main gear synchronously rotates at a second direction opposite to the first direction.

1. A biaxial pivot mechanism for rotating a first casing relative to a second casing, the biaxial pivot mechanism comprising:
at least one fixing component, the fixing component comprising a first area and a second area; a first shaft disposed on the first area of the fixing component and connected to the first casing; a first main gear disposed on the first shaft in a coaxially rotary manner; a second shaft disposed on the second area of the fixing component and connected to the second casing; a second main gear disposed on the second shaft in a coaxially rotary manner; and a transmission gear set engaged between the first main gear and the second main gear, wherein as the first main gear rotates at a first direction, the transmission gear set is driven by the first main gear to synchronously rotate the second main gear at a second direction opposite to the first direction.
