The mystery of the small hinge and the big role of the notebook hinge

(Summary description)When it comes to the hinge, maybe few people pay attention to it, because everyone defaults to it as an innocuous accessory on the notebook, as long as the screen can be opened and closed smoothly. In fact, the reel is not simple. Whether its design is good or bad will not only affect the overall style of the notebook, but also affect the port arrangement of the notebook. The poor hinge design can cause the hinge to break and the fixing point of the casing to be damaged, or cause the screen cable inside the hinge to break, which in turn causes various failures of the notebook. Therefore, the shaft design cannot be ignored!

When it comes to the hinge, maybe few people pay attention to it, because everyone defaults to it as an innocuous accessory on the notebook, as long as the screen can be opened and closed smoothly. In fact, the reel is not simple. Whether its design is good or bad will not only affect the overall style of the notebook, but also affect the port arrangement of the notebook. The poor hinge design can cause the hinge to break and the fixing point of the casing to be damaged, or cause the screen cable inside the hinge to break, which in turn causes various failures of the notebook. Therefore, the shaft design cannot be ignored!

Concave and convex, different characters

Although the hinges of notebooks have various shapes, from the perspective of basic structure, they can be divided into two categories: one is that the fixed end of the hinge is on the host, and the movable part is protruding and connected to the screen, forming a protruding structure; the other The quasi-spindle is fixed on the screen, and the movable part sinks and is connected to the host, forming a sinking structure.

The biggest advantage of the protruding hinge is that when it is opened, the screen as a whole rises upward, so that the screen will not block the rear of the notebook. Therefore, various ports, cooling holes, etc. can be conveniently set on the rear of the notebook. From the point of view of making full use of the notebook space and increasing the number of ports, it is very advantageous. At the same time, since the protruding rotating shaft is not easily blocked during rotation, the angle at which the screen can be opened is relatively large.

While there are many advantages to raised hinges, there are fewer notebooks today with raised hinges. 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 top cover of the notebook has to be thicker to cover the hinge. For notebooks that use LED backlight systems and pursue thin and light, the use of protruding hinges is naturally a bit inappropriate.

The sunken shaft is a good solution to this problem. The connection point of the sunken hinge is located in the thicker part of the main unit, so that the upper cover of the notebook will not be forced to increase in thickness due to the hinge. At the same time, when the sunken hinge is opened, the screen will sink down, so in some crowded environments, it will be more convenient to use a notebook with a sunken hinge.

But there are also some problems with the sunken shaft. For example, it is easy to block the rear of the notebook, which makes it impossible to set the port on the rear of the notebook. For another example, when rotating, the screen is easily blocked by the back of the notebook.

In general, there is no absolute difference between the protruding shaft and the sinking shaft, and the design should be determined by looking at the specific model. In general, large-screen notebooks, business notebooks, and full-featured notebooks often use protruding hinges in consideration of expansion performance and viewing comfort. For netbooks, thin and light notebooks and fashion notebooks, in order to control the thickness of the upper cover of the notebooks, sunken hinges are often used.
