Hinge device, open-closed device and portable machine

Abstract

A hinge device is provided with a first housing and a second housing which can be opened or closed with each other and are connected together. The hinge device is composed of an elastic mechanism and a friction mechanism which are mutually connected with a hinge shaft. The elastic mechanism includes a mounting assembly a cam slide member, a hinge shaft, an elastic cam assembly, a supporting assembly, and a rotation transmitting assembly. The mounting assembly is arranged on the first housing, and can be also used as a spring box. The cam slide member slides to a direction with the help of an elastic device, and is arranged in the mounting assembly. The hinge shaft is arranged between two side plates of the mounting assembly and can not rotate. The elastic cam assembly presses against the cam slide member and can be arranged on the hinge shaft rotatingly. The supporting assembly can be rotatingly arranged on the hinge shaft, and is connected with the second housing. The rotation transmitting assembly transmits the rotation of the supporting assembly to the elastic cam assembly.

Description

technical field [0001] The present invention relates to a hinge device, an opening and closing device, and a portable machine, which can connect the first casing and the second casing constituting a portable machine such as a notebook computer in an overlapping state, and can make the It rotates relative to each other. Background technique [0002] As for the notebook computer, which is one of the portable machines, it has a first housing with a keyboard on its upper surface, and a second housing with a display portion. The first housing and the first housing are connected by a hinge device The mutual openable and closable connection of the second shells is a technology known to the public. The second casing of the notebook computer is connected to the upper rear part of the first casing by a hinge device and can be opened and closed. Overlapping the second casing on the first casing can make it closed, and the second casing can switch from the overlapping state to the fir...

Problems solved by technology

Therefore, it is difficult to assemble it to make it operate correctly. In addition to being unable to obtain a relatively stable friction torque, the friction mechanism also has the problem of not being able to generate a stable friction torque.

[0007] In addition, if a pair of hinge devices are used as the opening and closing device of a portable machine for a notebook computer, when the second casing is bounced relative to the first casing by the pop-up mechanism, due to the relatively violent action and the Due to the function of the adsorption mechanism, when the second housing is closed and operated relative to the first housing, the rotation of the support assembly becomes stronger, causing the second housing to emit intense noise relative to the first housing, so there is still room for improvement in operability
