For example, the damping protrusion 510 may be mounted in the damping housing 520 so as to be linearly movable. However, in some cases, the damping rod may be mounted outside the damping housing.

In the embodiment of the present invention, for example, the damping rod 530 is formed in a rod shape having a predetermined length, but the shape and structure of the damping rod 530 may be variously changed according to the damping conditions.

In addition, a damping guide 540 may be provided at an end of the damping rod 530, and the damping rod 530 may be in contact with the damping protrusion 510 through the damping guide 540. The damping guide may be configured to be in line contact or point contact along the surface of the damping protrusion, and in some cases, the damping guide may be configured to be in surface contact along the surface of the damping protrusion.

The damping guide 540 may be formed of a conventional plastic material, but polyacetal (polyoxymethylene) is required because it is required to use a material having excellent mechanical, thermal, and chemical properties, and excellent dimensional stability even in a wide range of long-term use temperatures. It is preferable to form using a lubricity material having excellent self-lubricating properties and excellent fatigue resistance, such as polyamide, polyamide, and polyamide imide.

In addition, the above-described guide bracket 600 may be formed with a seating portion 640 for seating the damping housing 520, the damping housing 520 may be modularized together with the guide bracket 600.

However, in some cases, the damping housing is provided on the first link frame. The damping protrusion may be formed in the first body. In addition, in the embodiment of the present invention has been described by way of example in which the damping rod is configured to contact the damping protrusion via the damping guide, in some cases, the end of the damping rod may be configured to be in direct contact with the damping protrusion.

The damping spring 550 provides an elastic force to allow the damping rod 530 to elastically contact the damping protrusion 510. For example, a conventional coil spring may be used as the damping spring 550, and may be interposed between the damping housing 520 and the damping rod 530 to elastically support the damping rod 530.

Hereinafter will be described the operation structure of the sliding and tiltable tablet computer according to the present invention.

6 to 9 are views for explaining the operation structure of the personal portable terminal according to the present invention. In addition, the same or equivalent portions as those in the above-described configuration are denoted by the same or equivalent reference numerals, and a detailed description thereof will be omitted.

As shown in FIG. 6, in the initial state (closed state), the first body 10 and the second body 20 are disposed to overlap each other. At this time, the first link member 200, the second link member 300 and the connecting link member 400 is arranged in a folded state folded between each other between the first body 10 and the second body 20. . In this way, in the initial state, the user can input or output various information by using the display unit 22 provided in the second main body 20.

Thereafter, in order to use the tablet computer with the second main body 20 opened with respect to the first main body 10, as shown in Figs. The two main bodies 20 can be opened with respect to the first main body 10. That is, when the lower end of the second body 20 is pushed up in a manner of sliding the slide part in a conventional slide type personal portable terminal, the first link member 200 and the second link with respect to the first body 10. As the member 300 rotates, the second body 20 may slide and move at a predetermined angle while being tilted with respect to the first body 10 to be tilted open. As such, when the second body 20 is opened, various types of information may be input or output using the interface unit 12 exposed on the upper surface of the first body 10.

In addition, the opening of the second body 20 to the first body 10 may be implemented in a semi-automatic manner by the driving force of the hinge device 700. That is, the first driven cam member 720 and the second driven cam with respect to the common drive cam member 710 as the common drive cam member 710 rotates together with the first link member when the second body 20 is opened. The members 750 may interact at the same time, and by this force, the rotation of the first link member 200 may be elastically implemented in a semi-automatic manner.

In addition, when the opening of the second body 20 proceeds for a predetermined time or more, the damping unit is operated and the damping force acts on the first link 100 member, whereby the moving speed of the second body 20 may be reduced. That is, as shown in FIG. 8, as the rotation of the first link member 200 proceeds for a predetermined time or more, the damping protrusion 510 may contact the damping rod 530, and the damping rod 530 may be in contact with the damping protrusion 510. The rotation speed of the first link member 200 may be reduced by the damping force as the elastic contact. Therefore, the opening movement speed of the second body 20 can be reduced by the damping force.

In the same manner as in the above-described opening, even when the second body 20 is closed, one end of the second link member 300 is pushed by the connection link member 400 and one end of the first link member 200. Since it can move in the direction away from the, when the closing of the second body 20 with respect to the first body 10 can be minimized, the closing movement speed of the second body 20 by the damping portion is also Can be slowed down.
