Description

Technical Field

[0001] The utility model relates to the technical field of rotating shafts, in particular to a rotating shaft device for a notebook computer. Background Art

[0002] Most laptop computers are clamshell type. To meet the design considerations of being thin, small and light, they are generally designed to consist of a base consisting of a main body and a keyboard, and an upper cover consisting of a display screen and a cover. When the laptop is not in use or has been used, the upper cover is closed on the base. When in use, the upper cover must be opened upward to a proper angle for easy operation. Therefore, the hinge device of the laptop becomes a major factor in determining whether the laptop is good or not. The weight of the upper cover of the existing laptop increases and the weight of the lower cover decreases, and the center of gravity of the laptop moves upward. If a traditional hinge device is used, once the upper cover is rotated at an excessive angle, the laptop may tip over or even fall over, resulting in damage to components.

[0003] Prior art, patent number (CN200420072668.9) mentions a hinge device for a laptop computer with a heavier upper cover, the hinge device includes a bracket fixed to the base of the laptop computer, a main shaft rotatably fixed to the bracket, a spring provided on the main shaft and in a maximum deformation state, and a spring adjustment steel sheet for adjusting the spring torsion, one end of the spring is fixed to the bracket, and the other end is fixed to the spring adjustment steel sheet, one end of the spring adjustment steel sheet is sleeved on the main shaft, and the other end is fixed to the rotating part of the display screen on the upper cover of the laptop computer. Therefore, when opening the laptop computer, the opening and closing force of the laptop computer is reduced by using the method of offsetting the torsion of the spring itself and the damping force of the main shaft, thereby facilitating the user.

[0004] In the prior art, a spring adjustment steel sheet is added, which effectively solves the problem that the weight of the upper cover of the existing laptop increases and the weight of the lower cover decreases, and the center of gravity of the laptop moves upward. If a traditional hinge device is used, once the angle of the upper cover is rotated too large, the laptop may tip over or even fall over, causing damage to components. However, when the laptop needs to be disassembled for repair, the hinge assembly that is already difficult to disassemble will become even more difficult to disassemble after the spring adjustment steel sheet is added, and its structure is too complicated. On the basis of being inconvenient for repair and disassembly, the production cost will inevitably increase. Utility Model Content
