Problems solved by technology

In the biaxial hinge described in Patent Document 1, a shaft mounted on a first element (casing) and a shaft mounted on a second element (casing) are connected through a connecting arm, and friction is provided on each shaft. The torque generation means is further equipped with a ring arm, but this configuration still cannot make the first element and the second element open more than 180 degrees, or allow the first shell and the second shell to open and close regularly

Embodiment 1

[0127] figure 1 (a) and (b) are schematic diagrams of a notebook computer 1 in one embodiment of the terminal device using the biaxial hinge of the present invention. The notebook computer 1 can be opened and closed through a pair of biaxial hinges 4 and 5 of the present invention The left and right parts of the rear of the first housing 2 are connected to the left and right parts of the rear of the second housing 3. The first housing 2 is provided with a keyboard part 2a, and the second housing 3 is provided with a display part 3a.

[0128] Since the configurations of the biaxial hinges 4 and 5 are substantially equal, only the biaxial hinge 4 is used for illustration in this embodiment, and the description of the biaxial hinge with the reference number 5 is omitted. As a matter of course, the structure of the hinge of reference numeral 5 can also be replaced by other types of hinges without affecting the operation of the device.

Embodiment 2

[0152] The main spirit of the invention described in Embodiment 1 is as follows: in the closed state where the first housing 2 and the second housing 3 overlap each other, only the second housing 3 can be placed relative to the first housing. 2 to open and close, when the second casing 3 is opened relative to the first casing 2, the first casing 2 cannot be opened and closed (or rotated) relative to the second casing 3 under this opening and closing operation. And, after the first casing 2 is opened to 180 degrees relative to the second casing 3, the first casing 2 can be opened and closed (or rotated) relative to the second casing 3, and here the opening and closing Under operation, the second casing 3 cannot be opened and closed relative to the first casing 2 .

[0153] In contrast to this, Figure 20 to Figure 22 The biaxial hinge of embodiment 2 shown in , in the closed state where the first housing 2 and the second housing 3 overlap each other, can allow the first housin...

Abstract

In order to provide a terminal device that can regularly open and close the first casing and the second casing at an angle of 0 degrees to at least 180 degrees, preferably at an angle of 360 degrees, and can be stable at any angle In the biaxial hinge of the present invention, the first hinge lever assembled in the first housing and the second hinge lever assembled in the second housing are connected and mutually rotatably arranged through the connecting element, and the first hinge lever A selective rotation restriction means is arranged between the second hinge rod and the first hinge rod and the second hinge rod are allowed to rotate when the first housing and the second housing are both in a closed state. The first housing and the second housing are in a closed state. When the second housing is relatively opened and closed, when one of the first hinge lever and the second hinge lever rotates, the rotation limiting means is selected to limit the rotation of the other one.

Description

technical field [0001] The invention relates to a biaxial hinge suitable for use in terminal devices such as notebook computers, portable computers or digital personal assistants (PDA). Background technique [0002] In a terminal device such as a notebook computer, a portable computer, or a PDA having a first housing provided with a keyboard part and a second housing provided with a display part, a single-axis hinge and a double-axis hinge are also included. The body is formed and connects the first casing and the second casing in an openable and closable manner in the upward and downward direction. After being opened to a degree, the second housing can rotate relative to the first housing in the horizontal direction. However, the biaxial hinge of the present invention relates to a biaxial hinge capable of opening the first casing and the second casing up and down by 180 degrees and a total of 360 degrees only through the biaxial body. [0003] In the prior art, the biaxia...
