When using the hinge assembly for a laptop computer, the mounting base 1 is installed on the main body of the notebook computer, and the mounting base 2 31 is installed on one side of the display screen of the notebook computer. During the installation process, the second clamping mechanism 25 is installed on the outer surface of the rotating shaft 22 to limit the rotation of the buffer unit 3, so that the display screen can only perform circular motion during the rotation process.

Example 2

As shown in Figures 1-7, on the basis of Example 1, the utility model provides a technical solution: preferably, the connecting mechanism includes a mounting base 21, one side of the mounting base 21 is fixedly connected to one side of the mounting bracket 251, the outer surface of the mounting base 21 is fixedly connected to a hinge seat 32, the damping mechanism includes a rotating rod 33, both ends of the rotating rod 33 are rotatably connected to the inner wall of the hinge seat 32, the outer surface of the rotating rod 33 is fixedly connected to a gear 35, the outer surface of the gear 35 is meshed with the outer surface of the damping gear 23, one end of the gear 35 is fixedly connected to a torque spring 34, the other end of the torque spring 34 is fixedly connected to the inner wall of the hinge seat 32, when the display screen of the notebook is opened and closed, the damping gear 23 and the gear 35 cooperate with each other, so that the display screen drives the damping gear during the opening and closing process. 23 rotates, thereby driving the gear 35 to rotate. When the gear 35 rotates, the torque spring 34 is distorted. Through the deformation of the torque spring 34, the display screen will have a certain resistance when opening and closing. When the display screen is opened and closed to a certain angle, the torsion of the torque spring 34 is released by the fault design of the damping gear 23, so that the torque applied when the display screen is opened and closed is re-accumulated, so that when the display screen is in a closed state, the display screen is not easy to open and close.

The working principle of the anti-loosening notebook computer hinge assembly is described in detail below.

As shown in FIG. 1-7, when using the hinge assembly for a notebook computer, the mounting base 1 is mounted on the main body of the notebook, and the mounting base 2 31 is mounted on one side of the display screen of the notebook. During the installation process, the second clamping mechanism 25 is mounted on the outer surface of the rotating shaft 22 to limit the rotation of the buffer unit 3, so that the display screen can only perform circular motion during the rotation process. When the display screen of the notebook is opened and closed, the damping gear 23 and the gear 35 cooperate with each other, so that the display screen drives the damping gear 23 to rotate during the opening and closing process, thereby driving the gear 35 to rotate. When the gear 35 rotates, the torque spring 34 is twisted, and the torque spring 34 is used to prevent the torque spring 34 from rotating. The deformation makes the display screen have a certain resistance when opening and closing. When the display screen is opened and closed to a certain angle, the fault design of the damping gear 23 is used to release the torque of the torque spring 34, so that the torque applied when opening and closing the display screen is re-accumulated, so that when the display screen is in a closed state, the display screen is not easy to open and close. At the same time, when the display screen is opened to a normal angle, it is not easy to close. If it is necessary to lock the angle of the display screen, by toggling the toggle plate 42, the toggle plate 42 drives the movable bracket 41 to slide under the limit of the limit block 43 and the limit groove 11, so that one side of the engaging tooth plate 44 is engaged with the outer surface of the damping gear 23, thereby facilitating fixing the angle of the display screen.

The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
