Description

Multi-axis synchronous pivot

The present invention relates to a multi-axis synchronous pivot, and more particularly to a thinned electronic device suitable for use with a flat longitudinal height multi-axis articulated pivot.

An electronic device such as a notebook computer generally has a host system end base and a liquid crystal display screen upper cover that can be opened, the system end base and the display screen end cover are disposed at two opposite ends at two opposite ends. Connected, for use, can open the liquid crystal display screen of the upper cover with the pivots as the action axis, and input the operation procedure of the input command through the control area of the base system end; when not in use, the system end and the display can be displayed The screen ends relatively close in the opposite direction of the opening action.

Most of today's pivots use a two-axis synchronous structure to synchronize the base and upper cover of the electronic device during opening and closing. However, one of the disadvantages of using a two-axis co-rotating pivot is that the degree of freedom of rotation of the pivot can not be increased, and the pivot itself itself has an outwardly open gap between the two shafts due to the use of the two-shaft transmission. The effect is poor. More importantly, in order to form a more aesthetically appealing aesthetic design, such modern electronic devices often have various softer curved shape requirements at the pivot mounting end. Generally, the pivots are designed to match such designs. On the demand, it is often inconvenient to carry out very complicated assembly processing procedures in the factory.

The use of multi-axis co-rotating pivots solves many of the above-mentioned problems associated with dual-axis co-rotating pivots, including the need for different profile curvatures of various pivots to create a more compact appearance. Protection and effective control of the curvature of the pivot. However, in the existing structural design of such a multi-axis co-rotating pivot, the power zone of the pivot mainly uses a spur gear set to transmit power, so that the longitudinal height and thickness of the entire biaxial pivot are difficult to reduce, in the notebook computer. The thinning of products such as the continuous evolution of mobile electronic devices has become a trend, and such dual-axis pivots using a spur gear power group cannot be fully applied to thin electronic devices.
