Insert-assembling type multi-section rotating shaft structure

Abstract

The invention discloses an insert-assembling type multi-section rotating shaft structure, which includes driving joint groups and servo joint groups, wherein at least two relative joint sheets and a middle linkage sheet group connected between the relative joint sheets are arranged on each driving joint group; each servo joint group is arranged between the two relative joint sheets, and comprises at least two servo sheets used for presetting cohesion linkage of synchronous initiation parts, at the mutually relative inward ends; the inward ends of the relative joint sheets are aligned with the outward ends of the servo sheets, and the outward ends of the two joint sheets form an insertion end; the outward end of each middle linkage sheet of the middle linkage sheet group is aligned with the inward end of each servo sheet of the servo sheet group, and the various parts are combined with each other through shaft pins; and the driving joint groups and the servo joint groups are arranged in a combination manner and are connected in series with the shaft pins, so that each relative joint sheet of the driving joint groups can perform free rotation around multiple rotation centers, and a smooth rotating shaft structure with two opening and closing ends is formed.

Description

technical field [0001] The invention relates to a plug-in multi-section rotating shaft structure, especially a rotating shaft structure that can be combined with electronic equipment as the axis of rotation, which can improve the degree of freedom of rotation and make the two ends of the electronic equipment rotate and open or close more smoothly. Background technique [0002] Taking electronic equipment such as notebook computers as an example, it usually consists of a base as the system end and a top cover for display. The action axis of the device can be lifted upwards to be in use state, or the upper cover can be reversely closed on the upper surface of the base to become a closed state. The importance of this type of pivot lies in the fact that in addition to the action axis of the electronic device itself, the structural design must take into account the operating angle when the top cover is opened (such as the top cover display screen of a notebook computer is usually...

Problems solved by technology

[0004] Since such existing pivots are arranged in a group, when the upper cover of the electronic device is opened, the coordination of the preset spindles of the two pivots that do not belong to the same action axis is not ideal when rotating; At the same time, the rotational freedom of the two pivots arranged close to the same center line is also limited, so that the smoothness of the rotation process of the entire electronic device is obviously insufficient no matter whether it is opened or closed.

[0005] Furthermore, when combining the rotating shaft with the electronic equipment, in order to achieve the appeal of aesthetic appearance, it is usually necessary to perform complicated opening and locking operations on the shell body, which increases the complexity of the assembly process and relatively increases the defect rate. Therefore, if this can be properly improved to simplify the processing, it will definitely enhance the competitiveness of the overall product
