Rotary shaft device and folding electronic device with same

Abstract

The invention discloses a rotary shaft device and a folding electronic device with same. The rotary shaft device comprises a bearing part, a first rotary connector, a second rotary connector, a friction mechanism and a holding mechanism, wherein the first rotary connector comprises a first rotary shaft and a first bracket, the first rotary shaft is pivotally connected to the bearing part, the first bracket is fixedly connected to the first rotary shaft; the second rotary connector comprises a second rotary shaft and a second bracket, wherein the second rotary shaft is pivotally connected to the bearing part and opposite to the first rotary shaft; the second bracket is fixedly connected to the second rotary shaft; the friction mechanism is used for providing friction force for rotating the first rotary shaft and the second rotary shaft; the holding mechanism can be used for keeping the first bracket and the second bracket in an open state. The rotary shaft device has relatively great rotary friction force, good rotary connecting effects, long service life, and stability and firmness in connection; the friction force is almost not damped after long-term use.

Description

technical field [0001] The invention relates to a rotating shaft device, in particular to a rotating shaft device and a foldable electronic device having the rotating shaft device. Background technique [0002] In the current information age, people's dependence on electronic products is increasing day by day. Today's electronic products require high speed, high performance, and light and thin requirements. For example, foldable electronic products such as notebook computers have gradually become the mainstream, and have become an indispensable tool in modern life. Generally speaking, the foldable electronic device adopts a folding method to reduce the storage area, so as to achieve the purpose of light, thin and short electronic products. [0003] The hinge device is a connection mechanism used in a foldable electronic device to open or close two main parts of the electronic product. For example, a notebook computer mainly includes a display and a host body, wherein the d...

Problems solved by technology

However, after the display and the host body are opened, they need to keep the open state. Therefore, this requires the rotating shaft device to have a relatively large rotational friction force. However, the current foldable electronic products have a relatively small rotating friction force , the reliability of the use of electronic products is poor. In addition, after a period of use, the friction force gradually becomes smaller, resulting in the failure of normal use of electronic products
