When it comes to pivoting, maybe few people pay attention to it, because everyone defaults it to an irrelevant accessory on the notebook, as long as the screen can be opened and closed smoothly. In fact, the shaft is not simple. Its design will not only affect the overall style of the notebook, but also affect the port arrangement of the notebook. The poor design of the rotating shaft will lead to the fracture of the rotating shaft, the damage of the fixed point of the shell, and the fracture of the screen cable in the rotating shaft, which will lead to various failures of the notebook. Therefore, the design of the shaft can not be ignored!
Different personalities
Although there are various forms of the rotating shaft of the notebook, it can be divided into two types according to the basic structure: the fixed end of the rotating shaft is on the main machine, the movable part is prominent and connected with the screen, forming a protruding structure; the rotating shaft is fixed on the screen, the movable part sinks, connected with the main machine, forming a sinking structure.
The biggest advantage of the raised shaft is that when it is opened, the whole screen is upward, so that the screen will not block the back of the notebook. Therefore, it is convenient to set various ports, cooling holes, etc. at the back of the notebook. From the perspective of making full use of notebook space and increasing the number of ports, it is very beneficial. At the same time, because the protuberant rotating shaft is not easy to be blocked when rotating, the screen can be opened at a larger angle.
Although there are many advantages of the raised spindle, the number of laptops using the raised spindle has decreased. Why does this happen? Because the protruding shaft is to ensure the strength and damping of the shaft, the protruding part should be large enough. In this way, the top cover of the notebook has to be made thicker to cover the rotating shaft. For the use of LED backlight system, the pursuit of light and thin notebook, the use of raised shaft naturally seems to be a little inappropriate.
The sinking shaft solves this problem well. The connection point of the sinking shaft is located in the thicker part of the main machine, so that the upper cover of the notebook will not be forced to increase the thickness due to the shaft. At the same time, when the sinking shaft is opened, the screen will sink. Therefore, in some crowded environment, using the notebook with the sinking shaft will feel more convenient.
But there are some problems in the sinking shaft. For example, it is easy to block the back of the notebook, so that the port cannot be set on the back of the notebook. For example, when rotating, the screen is easily blocked by the back of the notebook.
Generally speaking, there is no absolute advantage or disadvantage between the raised shaft and the sinking shaft, but it depends on the specific model to decide which design to adopt. Generally, large screen notebooks, commercial notebooks and full function notebooks, considering the expansion performance and viewing comfort, tend to use a raised shaft. For netbooks, light notebooks and fashion notebooks, in order to control the thickness of the top cover of the notebook, they often use the sinking shaft.
