Description

Structure of chain set for rotation shaft

Technical Field

The present invention relates to a hinge assembly structure, and more particularly to a hinge assembly structure with a hinge assembly that can partially hide a synchronous rotating assembly to protect and reduce powder and oil.

Background

It is known in the art that a hinge or shaft that can be rotated back and forth by an external force is assembled to an electronic device (e.g., a mobile phone, a notebook computer, a PDA, an electronic book, etc.) such that an upper cover or a display screen can be rotated to open and close. For example, taiwan patent nos. 97222022 entitled "pivot structure" and 98207366 entitled "pivot structure" all provide typical embodiments.

In order to provide a liftable portion (e.g., a screen) of an electronic device with more operation modes and application ranges, the prior art also discloses a structure in which a dual hinge shaft is disposed between two pivoting modules, so that the two modules can generate different operation modes or rotation angles; for example: taiwan patent No. 99211350, "double pivot HINGE", 99225737, "double pivot HINGE", US 7512426B 2, "MOBILE communication DEVICEs with synchronization HINGE" patent, and so on, all provide possible embodiments.

The above-mentioned conventional pivot structure is usually disposed in two groups at two sides of the pivot joint of the display module and the machine body module of the electronic device (such as a notebook computer) in consideration of the strength of the supporting structure and the smoothness of the movement. Therefore, when the operation display screen or the display module rotates and lifts, the coordination of the rotating shaft is not ideal; meanwhile, the rotational freedom of the two pivot devices arranged close to the same central line is limited, so that the smoothness of the movement of the whole electronic equipment is poor in the opening or closing rotating process.

In order to improve the above situation, the prior art also discloses a technical means of applying multiple rotation centers to the pivoting device; for example, taiwan patent nos. 101224879 entitled "multi-section pivot structure" and 101224880 entitled "insertion and assembly multi-section pivot structure" all provide specific embodiments, respectively. The reference data is combined by an active joint group and a follow-up joint group; a middle linkage sheet group is arranged between two opposite joint sheets of the active joint group, and the two opposite joint sheets are provided with synchronous actuating parts which are connected with the middle linkage sheet group; the follow-up joint group is provided with two follow-up pieces which are arranged between two opposite joint pieces of the driving joint group; the inward end of the relative joint sheet corresponds to the outward end of the follow-up sheet, and the shaft pin is combined; the position of the middle linkage sheet group towards the outer end corresponds to the position of each follow-up sheet towards the inner end, and a shaft pin is combined; the plurality of active joint sets and the plurality of slave joint sets are arranged in a combined manner to form a multi-section rotating shaft structure.

However, in practical applications, as the two pivotally connected modules are covered or unfolded, the linking parts of the rotating shaft assemblies can generate friction, which causes powder falling and oil discharging; in the implementation structure disclosed in the prior art, the link portion of each rotating shaft assembly is directly exposed to the outside, so that the powder falling and oil discharging directly pollute the surrounding environment during use, thereby forming application defects.
