Problems solved by technology

[0007] However, due to the above-mentioned multi-section synchronous opening and closing shaft structure, it is necessary to combine multiple toothed pieces in order to obtain good transmission and the torque required to support the rotation angle, resulting in too many other components and poor production quality. It is not easy to control the disadvantage of uniformity; and it is difficult to control the tightness between the combined pieces, resulting in the leakage of lubricating grease; obviously, there are still many areas to be improved in terms of implementation

Abstract

A multi-joint synchronous rotary axle structure includes a middle shaft and two parallel side shafts at two sides of the middle shaft. A first synchronous actuating assembly and a second synchronous actuating assembly are provided at two opposite positions of the middle shaft and the side shafts, which are connected in a reverse link relationship. The two side shafts can be rotated about the middle shaft to generate a synchronous reverse turning. A two-way shaft plate is provided between the middle shaft and each of the side shafts to provide the torsion of tuning so as to form a compact multi-joint synchronous rotary axle structure.

Description

technical field [0001] The invention relates to a multi-section rotating shaft structure, especially a rotating shaft structure that can be combined with two opposite folding and unfolding devices for synchronous rotating and unfolding operation. It has the advantage of being simpler and more feasible than the traditional one. Background technique [0002] Taking the electronic equipment that has been widely used nowadays as an example, it is usually composed of a base as a system end and a closing part as a display. The base and the closing part are connected by a pivot. And make the upper joint part can lift upwards with the pivot as the action axis to the use state, or reverse the upper joint part to be closed on the upper surface of the base to become the closed state. The importance of this type of pivot lies in that besides being the axis of action of the electronic device itself, the structural design must take into account the opening of the upper part to reach the o...
