Description

Integrated hinge module {INTEGRATED HINGE MODULE}

The present invention relates to a hinge module which is installed to be rotatable in a direction perpendicular to the opening and closing shaft at the same time the sub body is opened and closed on the main body, in particular the opening and closing operation of the sub body and the rotation perpendicular to the opening and closing shaft The integrated hinge module of the portable wireless terminal configured to facilitate the opening and closing operation of the terminal by providing the installation space of the flexible printed circuit drawn out from the main body to the sub-body and at the same time implementing the rotation operation as a single module. It is about.

In recent years, due to the development of the electronic communication industry, portable wireless terminals are becoming smaller and thinner, and their functions are diversifying. For example, a speaker device capable of realizing melody of various chords is being installed, and a color display device of tens of thousands to hundreds of thousands of pixels is being implemented, and the situation is racing to further develop such a function.

The portable wireless terminal has been introduced with various functions corresponding to the high definition color display device described above. For example, a compact lens for video communication, a digital camera, or a camcorder can be used. An optical imaging device such as an assembly can be provided in the terminal. The optical photographing apparatus may be detachably mounted to the terminal, or may be installed in a built-in type. In the case of the built-in type, it is generally installed in the hinge module for mechanically connecting the main body and the folder, the mounted optical imaging device may be installed to be rotated 360 degrees with respect to the hinge axis. Therefore, the user is configured to photograph a desired subject at a desired position at a desired time with a terminal equipped with an optical photographing apparatus and to immediately display or download data on the photographed subject by connecting to a PC.

Furthermore, the folder of the terminal with the above-described optical imaging equipment is configured to be rotatable in a direction perpendicular to the hinge axis direction connecting the main body and the folder. More preferably, it is configured to be able to rotate 360 degrees. Therefore, two or more hinge modules are applied to the terminal, a hinge module used to open and close a folder about a hinge axis with respect to the main body, and a hinge capable of rotating the folder in a direction perpendicular to the hinge axis direction. You will use modules. In the latter case, it is generally referred to as a rotary hinge module.

Like the existing hinge module, the rotary hinge module also has a hinge cam having a ridge portion and a hinge cam having a valley portion mating with the ridge portion of the hinge shaft, and a hinge spring for pressing the hinge cam or the hinge shaft in a predetermined hinge housing. It can be configured in a way that is received sequentially, other additional fixing means may be used.

However, as described above, in order to rotate about two axes, the existing hinge module is equipped with one hinge module on the side hinge arm of the terminal, and the rotary hinge module is mounted on the center hinge arm in a direction perpendicular to the hinge module. As a result, the number of assembly operations increases, and the volume of the terminal increases. In addition, since the folder of the terminal is rotated in a fully open state (for example, having an angle of 150 ° to 180 °), it causes a lot of inconvenience for the user to perform a function as a digital camera or a camcorder.

In order to overcome this problem, the applicant of the present application filed an integrated hinge module as Utility Model Registration No. 2003-0015961 dated May 23, 2003. The integrated hinge module filed by the present applicant is simplified by integrally forming a hinge module that normally opens and closes the terminal and a rotary hinge module that rotates in a direction perpendicular to the hinge axis, and simultaneously controls the opening and closing operation when converting to the camcorder mode. It flows arbitrarily to prevent malfunction when shooting a subject.

However, since the above-described integrated hinge module is opened in two-stage at an angle of 90 degrees or more, when opening the terminal for a call, the user must perform two-stage opening and closing operation that is not desired, and is drawn out to the sub-body on the main body. The flexible printed circuit, which is an electrical connection means, also has a configuration that is wound around the axis of the rotary hinge module, causing a problem that the flexible printed circuit is entangled during operation.

In order to solve the problems as described above, the present invention consists of a hinge module for opening the terminal and a rotary hinge module for rotating the axis in a direction perpendicular to the opening and closing shaft integrally, reducing the number of assembly operations, the terminal To provide an integrated hinge module configured to contribute to the miniaturization of the.

Another object of the present invention is to provide an integrated hinge module which is installed to be rotatable in a state in which the folder is opened at 90 degrees in the subject photographing mode and is opened to a predetermined call opening angle at a time in the call mode.

Another object of the present invention is to provide a separate installation space in which the flexible printed circuit drawn out from the main body to the sub-body is installed, thereby preventing the disconnection due to the twist of the flexible printed circuit during operation of the terminal. It is to provide an integrated hinge module configured to prevent.

Still another object of the present invention is to provide an integrated hinge module configured to allow a user to conveniently use various functions of the terminal.
