Description

Pivot structure with dual guide rails

The present invention relates to a pivot structure, and more particularly to a pivot structure having a dual guide track.

Electronic products such as mobile phones, notebook computers, and PDAs often need to be used with a reciprocating pivot or a rotating shaft. Therefore, a two-axis pivot structure appears on the market to provide electronic products for biaxial reciprocating rotation, so that the keyboard base and the display screen can be rotated relative to the pivot structure respectively; moreover, the keyboard base and the display screen are achieved. It can rotate 360° back and forth.

Please refer to FIG. 1 , which is a conventional two-axis pivot structure, which mainly includes a first fixing component a1 , a second fixing component a2 , a first rotating shaft a3 and a second rotating shaft a4 , and the first rotating shaft a3 pivot Connected to the first fixing component a1 and rotatable relative to the first fixing component a1, the second rotating shaft a4 is pivotally connected to the second fixing component a2 and rotatable relative to the second fixing component a2, and the first rotating shaft a3 and the keyboard are fixed. Then, the second rotating shaft a4 is fixed to the display screen, so that the keyboard base and the display screen can be rotated relative to the first fixing component a1 and the second fixing component a2.

However, the above-mentioned biaxial pivot structure has the following disadvantages. First, the first rotating shaft a3 and the first fixing component a1, the second rotating shaft a4 and the second fixing component a2 respectively have a guiding groove a5 and a protruding block a6. The pivoting effect is achieved, but the single guiding groove a5 and the single protrusion a6 are liable to cause unstable situations such as shaking and shaking on the rotation; second, the first solid The combined components of the fixed assembly a1 and the second fixed assembly a2 are numerous and complicated, resulting in problems such as difficulty in assembly and high cost of the two-axis pivot structure.
