Stable opening and closing electronics

Abstract

The invention discloses a stably opening and closing electronic device which comprises an upper cover body, a bearing seat and an opening and closing hinge group, wherein the opening and closing hinge group comprises a connection part, the upper end of the connection part is pivoted at the upper part of the back of the upper cover body through a first pivoting part, and the lower end of the connection part is pivoted at the right part of the bearing seat through a second pivoting part, therefore, the edge at the bottom of the upper cover body can slide along the upper surface of the bearing seat, a track part is arranged at the right part of the upper surface of the bearing seat along the edge of the bottom of the upper cover body, a pin rotating part is connected at the bottom of the upper cover body, a sliding part is pivoted with the pin rotating part, and the sliding part is matched with the track part. With the adoption of above structure, the stably opening and closing electronic device has the advantages that the occupying space is small when the electronic device is opened, the opening force does not need to be specially controlled, and the upper cover body cannot slide down automatically in an opening state.

Description

technical field [0001] The invention relates to the technical field of electronic devices, in particular to an electronic device with stable opening and closing. Background technique [0002] The portability of electronic devices such as notebook computers, PDAs (Personal Digital Assistant), and mobile phones is increasing day by day, and their appearances are becoming lighter, thinner, shorter, and smaller. For this reason, it is mostly designed as a clamshell. Generally, it includes an upper cover body and a bearing seat pivotally connected together at the edges. When in use, it is only necessary to lift the upper cover body so that the upper cover body and the bearing seat are at a certain angle; when carrying the upper cover body and the bearing seat Fold and fit together. Its defect is that: the pivot joint between the upper cover and the bearing seat is located at the edge of the two, and the angle between the two is usually greater than 90° during use, thus occupyin...

AI Technical Summary

Problems solved by technology

The disadvantage is that the pivot joint between the upper cover and the bearing seat is located at the edge of the two, and the angle between the two is usually greater than 90° during use, thus occupying a large space

However, such a pivotal connection forces the user to reasonably grasp the force when opening the upper cover. If the force is slightly greater, even if the upper cover leaves the bearing seat, the opening structure of the electronic device will not be stable enough.
