Owning a laptop is now ubiquitous as the price of laptops continues to drop and people's demands continue to increase. Along with it, there will be some common problems in the notebook, one of which is the failure of the notebook hinge.

1. Notebook shaft life failure:

Notebook shafts have a certain lifespan. For example, a notebook shaft SMS-ZZ-259 independently developed and produced by Smooch passed the 2W swing test with a loss rate of about 15%. I looked at the structure of the notebook shaft (the principle is to use the spring to radially press the rotating ring to be in close contact with the base. That is, by friction (the principle is friction) In addition, the notebook shaft is usually made of metal material, which may corrode In addition, the rotating shaft will be coated with oily substances that play a lubricating role, and long-term use may also cause the lubricating effect to gradually decrease. Due to the reduced friction, the display screen will be opened loose.

2. The notebook shaft is broken

Notebook shafts are often made of powder metallurgy, zinc alloy, high carbon steel, stainless steel and other materials. Notebook hinges with different functions will undergo various tests when they leave the factory, and the torque test is one of them. In the process of use, it is often easy to cause the notebook shaft to break due to excessive force, and the screen will be stuck or cannot be opened at all.

3. The fixed point of the notebook hinge shell is damaged

The hinge of the notebook is loose when it is connected to the host computer and the display screen. It is often because the hinge of the notebook is not tightened tightly during assembly or loosened later, which causes the fixing point of the hinge shell to be easily damaged.

4. The screen cable in the hinge is broken

A bad hinge design may cause the hinge failure but not cause the normal use of the notebook computer, or cause the screen wire in the hinge to break, which will lead to various failures of the notebook. Similar problems, if you understand the structure of the notebook shaft, you can analyze and solve the fault yourself. Otherwise, you can send the whole computer to the official after-sales service center of the corresponding brand, and professional maintenance engineers will disassemble the machine for inspection and maintenance.

Application of notebook hinge:

Here, let’s popularize the knowledge on the structure of the notebook hinge. As the iconic element of the notebook computer, the hinge is an important factor that distinguishes the notebook computer from the tablet computer. A computer with a fixed hinge must be a laptop, and a computer with a detachable hinge is generally a PC tablet 2-in-1 laptop promoted by Intel but without a hinge, it must be a tablet.

One of the key factors that affects the user experience is the opening and closing angle of the screen. It can be said that the larger the opening and closing angle of the laptop, the better the experience. Generally, the maximum opening and closing angle of the hinge of a notebook computer is about 130°, and when we use a notebook computer, there are always many different placement methods. At this time, if a larger opening and closing angle is required, such a hinge design will inevitably affect the user's experience. Therefore, there are many notebook computers with an opening and closing angle of 180° on the market.

So, how to do the maintenance of the notebook shaft?

1. The opening method "gesture centering" is conducive to the same force on the left and right shafts and prolongs the service life!

2. Opening strength "Open light" notebook hinge is a kind of hinge with damping and self-locking function. It has a special structure inside, and requires a certain torque to open and close. If the force is too strong, the parts will wear more, the damping force will decline too fast, and the service life will be affected!

3. The screen should be opened slowly. The damping force of the rotating shaft comes from the friction force of the internal parts. During the friction, a small part of heat is generated. Therefore, the opening speed is slow, which effectively prevents the temperature from being too high.

4. The principle of not opening and closing frequently is very simple. It is like: to break a wire, you only need to fold it quickly at one point. At this time, a lot of heat is generated, and it is very hot. !

I believe that through the previous introduction, everyone will realize one thing - the notebook hinge may seem inconspicuous, but its function cannot be ignored. Different hinges endow the notebook with different styles, allowing the notebook to have a different appearance and even new functions. Among some innovative models and concept models, we often find that the role of the shaft cannot be ignored. It can be said that the change in the shape of the notebook hinge is the epitome of the evolution of notebook functions and the improvement of the level of industrial design.
