The role of the shaft in the notebook computer

Although the protruding shaft has many advantages, the number of notebooks using the protruding shaft has decreased. Why does this happen? Because the protruding shaft is to ensure the strength and damping of the shaft, the protruding part must be large enough. As a result, the upper cover of the notebook must be made thicker to cover the rotating shaft. For the use of LED backlight system, the pursuit of thin and light notebook, the use of protruding shaft naturally seems a bit inappropriate.

The sinking shaft is a good solution to this problem. The connection point of the sunken shaft is located in the thicker part of the host, so that the upper cover of the notebook will not be forced to increase in thickness due to the shaft. At the same time, when the sunken shaft is opened, the screen will sink. Therefore, in some crowded environments, it will be more convenient to use a notebook with a sunken shaft. The opening angle of the screen of the sunken shaft can only reach 120 degrees to 130 degrees. Generally speaking, the protruding shaft and the sinking shaft are absolutely different from each other, but the detailed model should be used to decide which one to use. In general, large-screen notebooks, commercial notebooks and full notebooks tend to use protruding hinges, taking into account the expansion function and viewing comfort. However, netbooks, thin and light notebooks and fashionable notebooks often use sunken shafts in order to control the thickness of the upper cover of the notebook. Hua takes Sony notebook, which everyone knows better, as an example. The cylindrical shaft it uses is quite distinctive. The cylindrical shaft has become an indispensable part of Sony's fashion modeling, which is a good contrast to the smart and light entertainment elements of Sony notebook. The circular shaft and the aesthetic lines near the shaft can have a great visual impact in the first place. In addition, the power supply start and power interface set at both ends of the cylindrical rotating shaft make the host look more cool, and also make the power switch of the notebook easier to operate and not easy to touch by mistake.

The L-shaped sunken shaft used by Lenovo IdeaPadY510 is also very distinctive. The wide rotating shaft enhances the damping of opening the upper cover, prevents the screen from shaking, disperses the force during opening and closing, and reduces the probability of damage to the rotating shaft. Its rotating shaft is integrated with the screen, making the transition between the host department and the screen smoother and more natural, changing the square image of the traditional notebook.
