Expansion hinge and electronic deivce having the same

Abstract

An expansion hinge including a torque module, two first brackets, two sliding brackets, two second brackets and two elastic modules is provided. The torque module is configured to provide torques. Thetwo first brackets are rotatably connected to two opposite ends of the torque module. The two sliding brackets are rotatably connected to the two opposite ends of the torque module. The two second brackets are slidably disposed in the two sliding brackets respectively. Each of the two elastic modules is disposed between the respective sliding bracket and the respective second bracket. The two sliding brackets are adapted to synchronously slide with respect to the two second brackets, each of the elastic modules is configured to push the respective sliding bracket and the respective second bracket to form a pulled-out state or a pushed-in state, and, in the stretched state, the two first brackets and the two sliding bracket s are adapted to rotate relative to the torsion module to overlapeach other or expand each other..

Description

technical field [0001] The present application relates to a hinge, and in particular, to a telescopic hinge used in a portable electronic device. Background technique [0002] Existing portable electronic devices such as smart phones, tablet computers, and notebook computers are becoming more and more popular, and are gradually moving towards the trend of large-screen display. Therefore, smart phones and tablet computers have been developed with dual-screen styles. The dual screens are connected to each other through hinges, which are suitable for relative unfolding or folding and switching to different situations of use. For example, in the unfolded state, images can be output simultaneously through the dual screens to increase the display range of the images. In the folded state, the dual screens are stacked up and down to reduce the area size of the portable electronic device, which is convenient for users to carry or store in a backpack. [0003] However, the existing ...

Problems solved by technology

[0003] However, the existing dual-screen electronic equipment using hinges has a large distance in the unfolded state, which results in poor viewing effect of the output image, and part of the hinges are located in the distance between the two screens, making the unfolded electronic equipment The appearance is not beautiful

In this way, it becomes an important development goal to develop a hinge to improve the shortcomings of the excessively large distance between the two screens and the unattractive appearance of the electronic device.
