Description

Pivot structure and electronic device using the pivot structure

technical field

The invention relates to a structural component of an electronic device, in particular to a pivot joint structure of the electronic device.

Background technique

An electronic device (such as a notebook computer) generally includes a screen and a host, and the screen receives a display signal from a system disposed in the host to display images. When an electronic device is used, the screen is often easily shaken by external force. Therefore, how to suppress the displacement of the screen shake and control the frequency of the screen shake has always been one of the key points in the design of the electronic device.

Generally speaking, in addition to strengthening the structural design on the system side and the screen side, traditional manufacturers also use a pivot structure arranged at the connection between the screen and the host to reduce screen shaking by using the torque generated by it. However, in order to effectively suppress the vibration or shaking of the screen, the volume of the hinge in the pivot structure must be increased accordingly to provide greater torque, which is not conducive to the utilization of the internal space of the electronic device. In addition, the system side and the screen side must also be adjusted in structure to be compatible with hinges with different specifications, which is really inconvenient. Therefore, a pivotal joint structure that can effectively suppress shaking is required.
