[0002] With the development of technology, various electronic products have emerged continuously, bringing huge changes to people's lives. In particular, the use of computers has changed people's lifestyles and accelerated people's living rhythms. In the past two decades, with the development of materials science and the emergence of smaller integrated chips, computers have evolved into notebook computers that are small in size, thin in thickness, light in weight and easy to carry. The die-casting part of the notebook hinge shaft gasket is an important component in the notebook hinge shaft, and its quality is directly related to the use of the notebook computer hinge shaft.
[0003] Most of the existing notebook hinge shafts adopt the damping hinge shaft method, but generally a single hinge shaft is set for opening and closing. When the single hinge shaft has a large opening and closing angle, the limit gasket will completely clamp the spring gasket, resulting in a limited clamping angle. Generally, the maximum opening and closing angle is 180 degrees. Existing notebooks may need to be opened and closed 360 degrees for use. In view of this, a die-casting part of a notebook hinge shaft with a large opening angle is proposed. Content of the Utility Model
