Problems solved by technology

[0004] However, most commonly used housing materials, such as plastics or some metals (stamping aluminum alloy, die-casting magnesium alloy, etc.), require a large gap around the shaft due to manufacturing precision and assembly precision. This seriously affects the sophistication and aesthetics of the product

Embodiment Construction

[0032] In order to facilitate the understanding of the technical solutions of the embodiments of the present invention, a common rotating shaft structure is described below.

[0033] figure 1 A schematic diagram for a laptop, such as figure 1 As shown, the notebook computer has two hinges, and these two hinges are used to connect the screen and the keyboard (that is, the system side), figure 1 The middle diagram shows the X direction and the Y direction.

[0034] figure 2 It is a schematic diagram of a common shaft structure, such as figure 2 As shown, the common shaft structure includes a first bracket and a second bracket, wherein the first bracket is fixed on the screen, and the second bracket is fixed on the keyboard, from figure 2 It can be seen that the rotation between the first bracket and the second bracket is realized by a set of torsion springs. In a common shaft structure, the first bracket must maintain a certain distance Y from the second bracket to ensure...

Abstract

The invention discloses a rotating shaft structure and electronic equipment. The rotating shaft structure comprises a first support, a second support and a rotating shaft assembly. The first end of the rotating shaft assembly is fixedly connected with the first support. A gear structure is arranged at the second end of the rotating shaft assembly. A first connecting part extends out of one end ofthe second support in the first direction. A through hole is formed in the first connecting part. The rotating shaft assembly penetrates the through hole in the first connecting part. A transmission part extends out of the first connecting part in the second direction. The transmission part is provided with a rack structure which abuts against the gear structure on the rotating shaft assembly. When rotating, the rotating shaft assembly drives the gear structure to move relative to the rack structure, thus, the rotating shaft assembly moves in the first direction or the third direction relativeto the second support, and the third direction is opposite to the first direction.

Description

technical field [0001] The invention relates to the shaft technology, in particular to a shaft structure and electronic equipment. Background technique [0002] The laptop's hinge connects the screen side to the system side and is a key moving part. When designing notebook products, the movement track of the shaft and the assembly tolerances of the parts of the shaft will be fully considered, and enough clearance will be reserved around the shaft for the movement of the shaft. Currently, the size of this gap is average for general-purpose notebook products. at 1.0mm. [0003] Under the trend of notebook products becoming more and more refined, it is required to minimize this gap as much as possible. When notebook products use high-strength / high-rigidity shell materials, such as mechanically cutting aluminum alloy, due to the high precision of shell processing, the rigidity of the product system is relatively small (that is, the amount of deformation is small), which can en...
