Computer Swivel Bracket MIM Parts
When it comes to the style of the Computer Swivel Bracket MIM Parts hinge, the common notebook hinge is the "sinking hinge". This type of hinge uses a relatively simple metal hinge connection inside, and the cost is relatively low, so the sunken hinge mostly appears on consumer-grade notebook bodies.

Notebook hinge bracket style
When it comes to the style of the Computer Swivel Bracket MIM Parts hinge, the common notebook hinge is the "sinking hinge". This type of hinge uses a relatively simple metal hinge connection inside, and the cost is relatively low, so the sunken hinge mostly appears on consumer-grade notebook bodies. Because the cost is relatively low and the damped hinge is basically relatively fixed, most laptops equipped with this hinge cannot open and close the screen with one hand, and their opening and closing angles are relatively fixed, and the extreme opening and closing angles Usually it's about one hundred and thirty degrees.
The protruding notebook shaft is fixed on the host, which can make the host and the screen fit closer together, and the opening and closing angle of the screen is larger, up to 150 degrees or even 180 degrees. At the same time, there may be interfaces or cooling vents on the back of the host. But the disadvantage is that the thickness of the screen must be consistent with the fixed place, and it cannot be too thin. Although the protruding shaft looks simple, modern technology has innovated and improved on the basis of tradition, allowing users to have a better experience. The Piayue screen that everyone liked at the time was to move the connection of the screen forward to make the screen closer to the user. The angle between the eyes and the screen is more ergonomic. At the same time, the electronic screen has been better supported, making the machine stronger after the electronic screen is turned off.
The laptop hinge is the soul of all parts of the laptop. Good or bad will not only affect the overall laptop experience, but also affect the port layout of the laptop. Poor shaft design, due to its low structural strength, will lead to cracking of the shaft, damage to the shell connection, and serious damage to the internal cable of the shaft, resulting in various problems in the notebook computer, reducing user experience, and directly affecting the service life of the computer !
Explanation of rated static load of bearing in notebook computer shaft factory
The load capacity of the bearing at rest is determined by the allowable plastic deformation. Plastic deformation in rolling bearings is unavoidable. If the allowable plastic deformation is limited, the static load capacity of the bearing is also small; if the allowable plastic deformation is large, the pits generated on the raceway will increase the noise and vibration of the bearing during operation and reduce the running accuracy. Reduced, affecting the normal work of the bearing.
The long-term bearing experience of the notebook computer shaft factory shows that in rolling bearings, the total plastic deformation (the plastic deformation of the raceway plus the plastic deformation of the rolling body) at the contact point between the rolling element and the raceway under heavy load is less than 10,000 times the diameter of the rolling element. When it is one-third, it does not have much impact on the normal operation of imported bearings. The static load capacity of the bearing determined under such plastic deformation conditions is called the rated static load, which is generally expressed by C0.
The rated static load of Computer Swivel Bracket MIM Partschang is determined under the assumed load conditions. For radial bearings, the rated static load refers to the radial load. For radial thrust bearings (angular contact ball bearings), it refers to the half-circle raceway in the bearing. The radial component of the loaded load, for thrust bearings the central axial load.
What is the structure of the notebook shaft?
Notebook hinges are familiar to friends who know how to use computers, but how to identify a good notebook computer? Maybe people still have a high level of configuration on the difference between good and bad notebooks, but a good notebook It can be distinguished from some small notebook hinges. Here we start with the structure of the notebook hinge. Let's explain in detail what are the shaft structures of Computer Swivel Bracket MIM Parts?
1. Laptop hinge mechanism - protruding type
Protruding shaft, this is a notebook shaft structure that we have seen more in the past. The fixed end of the rotating shaft is on the main body, and the movable part protrudes and is connected with the screen; the other type is a sunken rotating shaft, which is fixed on the screen, and the movable part sinks and is connected with the main frame.
The advantage of the protruding Dongguan hinge is that the screen as a whole rises upwards when it is opened, and the screen does not block the rear of the notebook. Various ports and cooling holes can be conveniently installed on the rear of the notebook. Therefore, the notebook space can be fully utilized and the number of ports can be increased. At the same time, since the protruding rotating shaft is not easily blocked when rotating, the screen can be opened at a relatively large angle, generally reaching 150-180 degrees.
Although the protruding hinge has many advantages, the number of notebooks using the protruding hinge has decreased. Why does this happen? This is because the protruding shaft must ensure the strength and damping of the shaft, so the protruding part must be large enough. As a result, the top cover of the notebook has to be made thicker in order to cover the hinge. For notebooks that use LED backlight systems and pursue thinness and lightness, the use of protruding hinges is naturally somewhat inappropriate.
2. Laptop shaft structure - sinking type
The sunken hinge is a popular notebook hinge structure at present. Its connection point is located in the thicker host part, which will not force the notebook cover to increase its thickness due to the hinge. At the same time, when the sunken hinge is opened, the screen will sink down. Therefore, in some crowded environments, it is more convenient to use a notebook with a sunken hinge. However, the sunken hinge easily blocks the rear of the notebook, making it impossible to set ports on the rear of the notebook. When rotating, the screen is blocked by the back of the notebook, and the openable angle generally can only reach 120-130 degrees.
Generally speaking, there is no difference between the protruding hinge and the sinking hinge, and it depends on the specific model to decide which design to use. In general, large-screen notebooks, commercial notebooks, and full-featured notebooks often use protruding hinges in consideration of expansion performance and viewing comfort. Netbooks, thin and light notebooks, and stylish notebooks often use sunken hinges in order to control the thickness of the top cover of the notebook. Here is a brief talk about the two forms of notebook hinge structure and there is no distinction between good and bad. As a good notebook manufacturer, it is necessary to choose a good notebook hinge manufacturer.
