Description

Sliding Portable Terminal {SLIDING TYPE PORTABLE TERMINAL}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable terminal, and more particularly, to a drive structure of a sliding portable terminal in which a pair of housings are slidably coupled in a state in which they face each other.

In general, a portable terminal is a device that allows a user to carry and use a mobile communication function. The portable terminal may be classified into a bar type, a flip type, and a folder type terminal according to its appearance.

The bar-type terminal is a type in which a data input / output means, a transmitter, and a receiver are mounted in a main body housing, and a keypad, which is a data input means, is exposed at all times, which may cause a malfunction, and the distance between the transmitter and the receiver. There is a limit to miniaturization due to securing problems.

The flip terminal comprises a main body, a flip, and a hinge module that connects the main body and the flip. The flip terminal is provided with a data input / output means and a handset, and the flip is a keypad for the data input means. Although the malfunction can be prevented, the flip type terminal also has a limitation in miniaturization due to the problem of securing the distance between the transmitter and the receiver.

The folder-type terminal includes a main body, a folder, and a hinge module for rotatably connecting the main body and the folder so that the folder is rotated and opened and closed. In the call mode, the folder is opened to secure a sufficient distance between the transmitter and the receiver, which is advantageous in miniaturization. For this reason, the foldable terminal is gradually becoming the mainstream of the portable terminal.

On the other hand, as the design of the portable terminal is diversified, a sliding portable terminal composed of two housings and one housing being opened and closed by slidingly moving on another housing is gradually overtaking the market share of the folding terminal.

The sliding portable terminal provides a switchgear that provides a driving force for sliding movement while coupling the pair of housings in a sliding movement. Such a switchgear is disclosed in Korean Patent Application No. 2006-63684 (Korean Patent Publication No. 2008-0005087, US Patent Publication No. 2008/0007878) and the like.

The sliding opening and closing device disclosed in the above-described patent patent allows sliding of the guide member and the slide member so as to be slidably movable, and by providing an elastic element such as a torsion spring therebetween, the cover can be slidably moved with respect to the body. It is configured.

However, the conventional sliding type terminal has a disadvantage that friction between the guide member and the slide member is inevitable by installing the elastic element. That is, when the cover is moved in the up and down direction with respect to the main body in the opening and closing operation, part of the elastic force generated by the elastic element acts in the left and right direction, it is inevitable to friction between the guide member and the slide member in the opening and closing operation. The friction between the guide member and the slide member not only generates noise in the opening and closing operation of the terminal, but also causes wear and foreign substances due to the friction and reduces durability of the opening and closing device.

In addition, in order to smooth the sliding movement, a certain distance is secured between the guide member and the slide member, which causes a flow in the front and rear direction of the cover with respect to the main body, which hinders the stability of the opening and closing operation, and also makes noise. There is a problem that increases the wear and tear.

Accordingly, the present invention is to provide a sliding type portable terminal that can reduce the friction in the opening and closing operation in coupling the pair of housings to the sliding movement.

In addition, the present invention is to provide a sliding portable terminal that can reduce the friction in the sliding opening and closing operation to reduce noise and improve durability.

In addition, the present invention is to provide a sliding-type portable terminal that can improve the stability of the opening and closing operation by smoothly opening and closing operation, by restricting the flow in an unnecessary direction.

In addition, the second magnetic body may limit the flow of the second housing in the front and rear directions as the first magnetic body faces each of the front and rear surfaces of the guide rail, respectively.

In addition, the second magnetic body may limit the flow of the second housing in the left and right directions, as the second magnetic body faces the first magnetic body at both side ends of the slide member, respectively.

In addition, the portable terminal may further include third magnetic bodies that are respectively installed on the guide rails, wherein the first magnetic body is in the center of the guide rail, and the third magnetic body is above and below the first magnetic body. It is disposed in each of the, it is preferable that the attraction force acts between the second magnetic body and the third magnetic body.

In this case, the second magnetic body may limit the flow of the second housing in the front and rear directions as the first magnetic body or the third magnetic body faces each of the front and rear surfaces of the guide rail, respectively.

In addition, the second magnetic body may restrict the flow of the second housing in left and right directions as the second magnetic body faces the first magnetic body or the third magnetic body at both side ends of the slide member, respectively.

The sliding type portable terminal configured as described above has a constant distance between the guide rail and the guide member for directly coupling the first and second housings due to the repulsive force between the first and second magnetic bodies, thereby preventing friction in the sliding opening and closing operation. It can prevent. Therefore, it is possible to prevent the noise and wear generated during the opening and closing operation of the sliding portable terminal. In addition, when the first and second magnetic bodies face each other on both sides of the guide rail, and the guide rail is installed adjacent to each other at both side ends of the second housing, the first and second magnetic bodies are both side ends of the second housing. Since the driving force is generated in the up and down directions in which the second housing is opened and closed, the guide rail, and ultimately, the second housing in the front, rear, left and right directions can be restricted.

In this case, the speaker module and the camera device may be installed adjacent to each other, and an upper end of the rear cover 102b may protrude rearward to secure a space for accommodating the speaker module and the camera device.

Since the second housing 102 overlaps the first housing 101 when the first housing 101 is closed, the front cover of the first housing 101 protrudes from the rear cover 102b. Grooves 115 are formed that can accommodate the broken portions.

Hereinafter, the coupling structure of the first and second housings 101 and 102 will be described with reference to FIGS. 1 and 2 again.

In order to couple the second housing 102 to the first housing 101, the guide member 201 is mounted to the first housing 101.

The guide member 201 is mounted on one surface of the first housing 101 and is positioned on the upper side of the keypad 111. The guide member 201 is coupled to enclose both side ends of the rear cover 102b and the second housing 102. The sliding movement of the will be guided. In order to mount the guide member 201, a mounting groove 119 adjacent to the keypad 111 is formed on one surface of the first housing 101.

Both side ends of the guide member 201 are provided with guide ribs 211 extending inwardly. The guide ribs 211 are formed at both side ends of the guide member 201, and the guide ribs 211 are substantially coupled to cover both side ends of the rear cover 102b so that the second housing 102 is formed. Guide the sliding movement of

Guide rails 221 are formed on the rear cover 102b of the second housing 102. One or more of the guide rails 221 may be formed, but in the present embodiment, an example is formed at both side ends of the rear cover. If necessary, additional guide rails may be installed on one surface of the rear cover 102b between the guide rails 221 shown in FIG. 1, and the number of the guide rails 221 may be manufactured in a manufacturing process of an actual product. The vendor may set this up appropriately.

Each of the guide rails 221 protrudes from both side ends of the rear cover 102b and extends along a moving direction of the second housing 102. Both side ends of the guide member 201, specifically, the guide ribs 211 are coupled to enclose the guide rails 221 so that the second housing 102 is slidably moved to the first housing 101. Bound.

Meanwhile, in the present embodiment, the guide rail 221 is an example formed in the rear cover 102b, but the rear side of the slide member having guide rails formed on both sides of the rear cover 102b separately from the rear cover 102b. It can be easily understood by those skilled in the art that the cover 102b can be mounted. In other words, in the present embodiment, the guide rail is formed on the rear cover as an example, but the rear cover of the present embodiment may be replaced with a slide member manufactured by a separate slide member or manufactured separately in actual production. .

The terminal 100 includes magnetic bodies 221a and 211a respectively installed on the guide rail 221 and the guide member 201, and a repulsive force is applied between the magnetic bodies to slide the second housing 102. In addition to generating a driving force to move, it maintains a constant distance between the guide rail 221 and the guide member 201. Hereinafter, the magnetic body installed on the guide rail 221 will be referred to as a 'first magnetic body 221a', and the magnetic body installed on the guide member 201 will be referred to as a 'second magnetic body 211a'. The third magnetic body 221b may be further installed on the guide rail 221, but the third magnetic body 221b may not necessarily be installed.

The first magnetic body 221a is installed at the center of the guide rail 221, and the second magnetic body 211a is installed at the guide member 201, more specifically, the guide rib 211. The magnetic bodies illustrated in FIG. 1 disclose an example in which the guide rails 221 and the guide ribs 211 themselves are magnetized. However, it is apparent that a separate magnetic body may be formed by attaching to the guide rail 221 or the guide rib 211.

When the second housing 102 slides and is positioned at a point at which the second magnetic body 221a surrounds the first magnetic body 211a, a repulsive force generated between the first and second magnetic bodies 221a and 211a. This is the maximum. In this case, the first magnetic body 221a has a tendency to move away from the point covered by the second magnetic body 211a. Therefore, the guide rail 221, the rear cover 102b and the second housing 102 are slidably moved by the repulsive force generated between the first and second magnetic bodies 221a and 211a.

On the other hand, on both sides of the guide rail 221, the second magnetic body 211a respectively faces the first magnetic body 221a to generate a repulsive force, so that the guide rail 221 is the guide member 201 or The non-contact with the guide rib 211 may be maintained. As a result, friction may be prevented from occurring in the opening and closing operation of the terminal 100, and the second housing 102 may be prevented from flowing in the front and rear directions. In addition, the second magnetic material 211a faces the first magnetic material 221a at both side ends of the rear cover 102b, which are at both side ends of the rear cover 102b, and the guide rails 221. Prevents the lateral end of rubbing against the guide rib 221.

This will be described in more detail through the opening and closing operation of the terminal 100 shown in FIGS. 2 to 10.

The third magnetic body 221b is installed on the guide rail 221 and interacts with the second magnetic body 211a to generate an attractive force. The third magnetic body 221b is disposed on the upper and lower ends of the guide rail 221, that is, on the upper side and the lower side of the first magnetic body 221a, respectively. Therefore, the guide rail 221 is provided with a driving force moving upward or downward on the guide member 201. On the other hand, the guide rail 221 is provided with the driving force to move to the upper or lower side of the guide member 201 only by the repulsive force generated by the first and second magnetic bodies (221a, 211a), the third magnetic body 221b is installed to generate an attractive force together with the second magnetic body 211a, thereby improving driving force for sliding the second housing 102. As a result, the third magnetic material 221b is to improve the driving force for slidingly moving the second housing 102. Even if the third magnetic material 221b is not present, the first and second magnetic materials 221a and 211a do not exist. Note that the driving force for moving the second housing 102 can be generated only by the repulsive force generated therebetween.

Meanwhile, the second and third magnetic bodies 211a and 221b are also disposed to face each other at both sides of the guide rail 221 and both side ends of the rear cover 102b, so that the second housing 102 is moved forward and backward. After that, the flow in the left and right directions can be restricted.

Hereinafter, the opening and closing operation of the terminal 100 will be described with reference to FIGS. 2 to 10.

First, FIGS. 2 to 4 show a state in which the second housing 102 overlaps the first housing 101. In a position where the second housing 102 overlaps the first housing 101, the guide rail 221 is moved to the lower side of the guide rib 211, and the second magnetic body 211a is It is positioned to surround the third magnetic material (221b) of the upper side. At this time, the repulsive force between the first magnetic body (221a) and the second magnetic body (211a) acts as a driving force for further moving the guide rail 221, the guide rib 211 of the rear cover (102b) Interfering with a portion of the upper end, the second housing 102 may maintain a stable stationary state. FIG. 3 illustrates the polar arrangement of the second and third magnetic bodies 211a and 221b when the second housing 102 overlaps the first housing 101, but the second and third magnetic bodies are illustrated. If the 211a, 221b can generate an attraction force, it may be changed from the polar arrangement shown in FIG.

5 to 7 illustrate a state in which the second housing 102 slides, and shows a state in which the second magnetic body 211a surrounds the first magnetic body 221a. At the point where the second magnetic body 211a surrounds the first magnetic body 221a, the repulsive force between the first and second magnetic bodies 221a and 211a is maximized, and the second housing 102 is configured as the first magnetic body 221a. The driving force acting in the lower or upper direction of the housing 101 is provided. Therefore, at the point where the second magnetic body 211a surrounds the first magnetic body 221a, the user may move the second housing 102 slightly if necessary, between the first and second magnetic bodies 221a and 211a. By the repulsive force of the second housing 102 is moved in the direction intended by the user. Of course, even at this time, the attraction force generated between the second magnetic body 211a and the third magnetic body 221b acts. FIG. 6 illustrates a polar arrangement of the first and second magnetic bodies 221a and 211a at a point where the second magnetic body 211a surrounds the first magnetic body 221a.

8 to 10 illustrate a state in which the second housing 102 slides upwardly of the first housing 101, and the second magnetic body 211a is disposed below the third magnetic body ( 221b). At this time, the repulsive force between the first and second magnetic bodies 221a and 211a still acts to generate a driving force for moving the guide rail 221 upward. However, the guide rib 211 may interfere with the inner wall of the second housing 102, which is not shown, so that the second housing 102 may no longer move upward and stably maintain the stationary state. FIG. 9 illustrates a polar arrangement of the second and third magnetic bodies 211a and 221b when the second housing 102 slides upwardly to the first housing 101.

Meanwhile, while the second housing 102 is stopped or slidingly moved, the second magnetic body 211a is positioned to surround any one of the first and third magnetic bodies 221a and 221b. In this case, the second magnetic material 211a faces the first or third magnetic material 221a and 221b on both surfaces of the guide rail 221 and at both side ends of the rear cover 102b, thereby providing the magnetic material. The driving force generated by the field acts only as a driving force for moving the second housing 102 upward or downward. In addition, the force generated between the magnetic material is the terminal by keeping the guide rail 221 spaced apart from the guide member 201, more specifically, the guide rib 211 without contacting the terminal 100. Is opened and closed in a magnetically levitated slide manner.

In the foregoing detailed description of the present invention, specific embodiments have been described. However, it will be apparent to those skilled in the art that various modifications can be made without departing from the scope of the present invention.
