Choose from a functional point of view
A notebook computer, the bottom cover is the main body such as the computer motherboard CPU keyboard, the top cover is the computer screen, and the middle is a Hinge connection. Therefore, where the computer shaft rotates, we need to be able to pass through the screen line.
At the same time, since the notebook screen can be held at will without shaking after opening and closing the notebook screen, it is necessary to select a damping axis. Usually when people use a laptop, the screen tilts about 130 degrees, which is a better choice. Comfortable reading angle.
Bottom line: Normally, the laptop axis is an arbitrary 130-degree stop damper axis. It is also one of our co-branded notebooks!
Select the life damping shaft
No one wants to use a laptop for one or two years, the screen will fall off! That's right, it's a matter of how many times the tree opens and closes! Under normal circumstances, we all think that the more time the better! It is scientific to define different areas for different products. For example, the normal life of a laptop is about 10 years, so the life of the tree should be the corresponding tree! The current number of opening and closing is 15,000 times, 4 times a day, and it can be used for 3750 days, about 10 years and 2 months.
Select the damping shaft according to the appearance of the product
These years, all kinds of ultra-thin laptops have become popular! To achieve this ultra-thin, it is inseparable from the role of the tie rod! Of course, there may be more innovative products in the future, so can hinges adapt to these new appearances? This is also a question that engineers should consider when developing products!
