Double rotating shaft structures and electronic equipment

Abstract

The embodiment of the invention discloses double rotating shaft structures and electronic equipment. The double rotating shaft structures comprise a first rotating shaft, a second rotating shaft, and a stroke sliding block, wherein a bulged first stroke bolt is arranged on the outer surface of the first rotating shaft; the second rotating shaft is parallel to the first rotating shaft, and a second stroke bolt is arranged on the outer surface of the second rotating shaft; the stroke sliding block is simultaneously sleeved at the periphery of the first rotating shaft and the second rotating shaft; a first spiral groove and a second spiral groove are formed in the stroke sliding block; the first stroke bolt is positioned in the first spiral groove; the second stroke bolt is positioned in the second spiral groove; when the first rotating shaft rotates, the first stroke bolt moves in the first spiral groove to promote the stroke sliding block to do linear motion at the periphery of the first rotating shaft along an axial direction of the first rotating shaft; and when the stroke sliding block does linear motion, by interaction between the second spiral groove and the second stroke bolt, the second rotating shaft is promoted to do synchronous rotation with the first rotating shaft.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a double-rotating shaft structure and electronic equipment. Background technique [0002] The double shaft structure is a shaft structure including two shafts. This dual-hinge structure is commonly used in various electronic devices such as notebooks or ultrabooks. The dual-shaft structure includes a synchronous structure that makes the two shafts rotate synchronously. In the prior art, the synchronous structure usually adopts a worm turbine. However, it is impossible to make the worm and turbine small, and it is very difficult to realize the further thinning of electronic equipment. Moreover, the synchronization of the two rotating shafts by using the worm and the turbine requires high manufacturing precision of the turbine and the worm. If the torsional forces of the two rotating shafts are different, it will be more difficult to control the turbine and the worm. In thi...

However, it is impossible to make the worm and turbine very small, and it is very difficult to realize the further thinning of electronic equipment

And using the worm and the turbine to realize the synchronization of the two rotating shafts requires high manufacturing precision of the turbine and the worm. If the torque of the two rotating shafts is different, it will be more difficult to control the turbine and the worm.

In this way, in the process of assembly and composition effect testing, it is easy to cause scrapping of the turbine and worm, resulting in a high scrap rate, resulting in high hardware processing costs, and a high probability of reassembly, resulting in high generation costs
