Description

HINGE DEVICE FOR PERSONAL PORTABLE DEVICE}

The present invention relates to a hinge device for a personal handheld device, and more particularly, to a hinge device for a personal handheld device that can contribute to miniaturization and can improve space utilization and design freedom.

Recently, personal portable terminals have been widely used as conveniences that anyone can easily carry and use freely anywhere.

Such personal portable terminals are generally bar-type personal portable terminals, flip-type personal portable terminals, folder-type personal portable terminals, and slide-type personal portable terminals according to appearance or operation. -type).

Also, recently, a tilting personal portable terminal has been proposed in which the second body can be tilted with respect to the first body at a predetermined angle. That is, in recent years, the terminal is mounted on a desk or a shelf, so that various image files and information can be comfortably checked through the display unit of the second body tilted with respect to the first body. Development of a tilting personal portable terminal capable of maintaining a constant display unit orientation has been made.

On the other hand, the conventional tilting personal portable terminal is configured such that the opening and closing operation of the second body with respect to the first body is implemented in a semi-automatic manner by the driving force of the actuator.

However, the conventionally known actuator has a limitation in reducing the thickness due to its structural characteristics, and since a space for mounting the actuator must be secured inevitably, it is difficult to form the thickness of the terminal more than a certain thickness. In addition, conventionally, since the actuator may be mounted only at a specific position, there is a problem in that design freedom and space utilization of the terminal are reduced.

In particular, when a folding hinge generally applied to a folding personal portable terminal is used as an actuator of a tilting personal portable terminal, there is a limit in reducing the thickness by a certain amount due to the structural characteristics of the folding hinge, and the folding hinge inevitably rotates. Since it is to be coaxially arranged in the terminal, it is difficult to slim the terminal and there is a problem that the design freedom and space utilization of the terminal is reduced.

Therefore, in recent years, various studies have been made to slim the terminal and improve design freedom and space utilization, but there is still insufficient development.

The present invention can contribute to the miniaturization, and provides a hinge device for a personal portable terminal that can improve space utilization and design freedom.

In particular, the present invention provides a hinge device for a personal portable terminal using an actuator that can be disposed coaxially with respect to the rotation center.

According to a preferred embodiment of the present invention for achieving the above object of the present invention, the hinge device for a personal portable terminal for opening and closing the second body with respect to the first body, respectively, to the first body and the second body A link connection part rotatably connected to guide movement of the second body relative to the first body; And a cam member having a cam surface, the cam member being provided to be elastically linearly movable to the first body, and a cam protrusion provided on at least one of the first and second links, and being in contact with the cam surface. And an actuator providing a driving force for semi-automatic opening and closing of the second body with respect to the first body.

The structure and characteristics of the link connection may vary in accordance with the required conditions and design specifications. For example, one end of the link connecting part is rotatably connected to the first body and the other end is rotatably connected to the second body, and one end is rotatably connected to the first body and the other end is connected to the second body. It may be configured to include a second link rotatably connected, the number and spacing interval of each link may be appropriately changed according to the required conditions and design specifications.

Alternatively, the link connecting portion may be configured to include a linking link with the first link and the second link, one end of which is rotatably connected to the first link and the other end of which is rotatably connected to the second link. One end may be connected to the first body so as to be slidably movable. Therefore, the distance between the second link and the first link by the connection link when the first link is rotated can be limited within a predetermined distance. In some cases, the link connecting portion may consist of only one link.

The arrangement of the cam projections can be changed in various ways according to the required conditions and design specifications. For example, the cam member may be disposed to be linearly movable in a direction orthogonal to the rotation centers of the first and second links. In some cases, the cam protrusion may be disposed to be linearly movable along another inclined direction with respect to the rotation center of the first link and the second link.

For reference, the cam protrusion is provided on the rotation axis of at least one of the first and second links, which is formed integrally with the first and second links such that the cam protrusion has the same center of rotation as the first and second links. It is to be understood that the structure of the cam protrusion may include both a structure directly connected to the rotation shafts of the first and second links, as well as a structure that is combined or separately coupled. For example, the cam protrusion may be integrally formed to have the same center of rotation at the end of the first link.

In addition, the first body may be mounted with a housing having a predetermined receiving space therein, the cam member may be accommodated in the housing to be linearly movable. In addition, the cam member may be formed with a guide rod, the housing may be formed with a guide hole for guiding the slide movement of the guide rod.

According to the hinge device for a personal portable terminal according to the present invention, it can contribute to miniaturization, and can improve space utilization and design freedom.

In particular, according to the present invention, since the actuator can be arranged coaxially with respect to the axis of rotation of the link connecting portion, the actuator can be freely arranged according to the required conditions and design specifications, and there is an advantage that the terminal can be made smaller. .

That is, when a clamshell hinge (see the conventional clamshell hinge of FIG. 5) applied to a clamshell personal portable terminal is used as an actuator, the clamshell hinge must be coaxially disposed on the axis of rotation of the link connection due to its structural characteristics. Since the space for mounting the folding hinge (particularly, the peripheral space adjacent to the rotating shaft) must be secured, it is difficult to make the terminal slim, and the design freedom and space utilization are deteriorated. However, according to the present invention, since the actuator can be disposed coaxially with the rotation axis of the link connecting portion, it is possible to prevent unnecessary thickness increase due to the mounting of the actuator, and the actuator can be arranged more freely regardless of the specific position. .

In addition, the present invention has the advantage of easy replacement and repair of the actuator.

In addition, according to the present invention, since the actuator can be mounted freely regardless of a specific position, it can be applied to various objects, there is an advantage in space utilization, and the assembly process also has a very simple advantage.

Further, according to the present invention, when opening and closing the second body with respect to the first body, by pulling and pushing the end of the second link by the connecting link, the lower end of the second body when opening and closing the second body is first By allowing the main body to rotate in a direction approaching the upper surface of the main body, the lifting phenomenon of the second main body with respect to the first main body during the opening / closing of the second main body is minimized. can do.

In addition, according to the present invention, since the lifting phenomenon of the second body with respect to the first body may be minimized during opening and closing of the second body, the force required for the opening and closing operation during the opening and closing operation may be effectively transmitted. For example, since the direction in which the force is applied during the opening operation may form a substantially straight line, it may be opened by a simple operation without the hassle of changing the direction of the force in the middle or changing the strength of the force. In other words, even by a simple operation of pushing up and opening the slide unit in a conventional slide type personal portable terminal, it means that the opening and closing operation of the second body can be implemented.
