The present invention relates to a portable terminal, and more particularly, to a sliding module of a portable terminal, which makes it possible to open and close a part of the first housing by slidingly coupling the second housing in the longitudinal direction of the first housing.

Generally, portable terminals are classified into bar type, flip type, and folder type terminals according to their appearance.

The bar-type terminal is a type in which a data input / output means and a handset are mounted in a main body housing, and a keypad, which is a data input means, is always exposed, which may cause a malfunction and to secure the distance between the handset and the handset. The problem is that miniaturization is limited.

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. The cover can prevent malfunction, but 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 to be opened and closed by rotating the folder. When the folder is in close contact with the main body, the keypad is placed in a call-waiting mode. Malfunctions can be prevented, and in the call mode, the folder can be opened to sufficiently secure the 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.

The flip type terminal or the folder type terminal is provided with a force in a direction in which the flip or folder is opened without further applying a force when the flip or folder rotates by a predetermined angle from the main body by a hinge module rotatably coupled to the main body. Below the angle is provided with a force in the direction in close contact with the body.

On the other hand, as the portable terminal design is diversified, a sliding type portable terminal which is composed of two housings and one housing is opened and closed by slidingly moving on the other housing is gradually commercialized.

In order to facilitate the use of the sliding type portable terminal, a sliding device capable of various types of semi-automatic operation has been provided. For example, Korean Patent Registration No. 350,313 (2004. 5. 3.) discloses a sliding module having a structure for generating a driving force using a torsion spring.

Such conventional sliding devices use various types of elastic members such as torsion springs or push rods, and when the housing of the terminal slides, the elastic member rotates about one end thereof to generate a driving force.

However, conventional sliding devices have a disadvantage in that the design of the product is difficult because the space for the elastic member to be rotated must be secured. That is, the wiring space of the flexible printed circuit connecting the circuit devices installed in each of the housings of the terminal should be secured. The wiring path of the flexible printed circuit is secured while securing the space for the elastic member to rotate in the sliding device. There are many restrictions. In addition, noise generated by friction with other components as the elastic member rotates, in addition to the friction sound generated by the housings of the terminal sliding, may cause discomfort to users. Moreover, in assembling the elastic member to the sliding device, it is also difficult to determine the assembly position of the elastic member for smoothly implementing the semi-automatic operation.

In order to solve the above problems, the present invention is to provide a sliding module of a portable terminal that is easy to assemble, easy to secure the wiring space of the flexible printed circuit.

In addition, the present invention is to provide a sliding module of a portable terminal capable of reducing the noise generated when the sliding movement, while enabling a semi-automatic sliding movement of the housings.

Accordingly, the present invention provides a portable terminal having a first housing, a second housing coupled to face the first housing and slidingly sliding, and a sliding module for slidingly coupling the second housing to the first housing. In the, the sliding module,

A guide member mounted to the first housing;

A sliding member mounted to the second housing;

Elastic members having both ends fixed to the sliding member in a state in which they are disposed parallel to each other along the sliding movement direction of the second housing; And

Guide wheels mounted on the guide member and moving in a state supported by outer peripheral surfaces of the elastic members,

The elastic members disclose a sliding module of a portable terminal for generating a driving force for moving the guide wheels to either of its ends.

The sliding module of the portable terminal according to the present invention arranges a pair of elastic members mounted on a slide member in parallel to each other, and guide wheels moving to the top or bottom of the elastic members while being supported on the outer circumferential surface of the elastic members. As a configuration mounted on the guide member, the elastic force of the elastic members act as a driving force for moving the guide wheels to either one of both ends of the elastic member.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, if it is determined that the detailed description of the related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is an exploded perspective view illustrating a portable terminal 100 having a sliding module 200 according to an exemplary embodiment of the present invention, and FIG. 2 is an exploded perspective view illustrating the sliding module 200 illustrated in FIG. 1.

As shown in FIG. 1, the portable terminal 100 including the sliding module 200 according to the preferred embodiment of the present invention includes a first housing 101 and a second housing 102, and the sliding module The 200 is interposed between the first housing 101 and the second housing 102 to slidably couple the second housing 102 to the first housing 101.

The sliding module 200 includes a guide member 201 and a sliding member 202, the guide member 201 is mounted to the front upper end of the first housing 101, the sliding member 202 is The mounting surface 129 is mounted on the rear surface of the second housing.

Referring to FIG. 10, the first housing 101 includes a keypad 111 and a talker unit 113 provided at the front side, and the second housing 102 has a display device 115 and a receiver unit installed at the front side. 117 and a functional keypad 119. The keypad 111 and the talker 113 of the first housing 101 are configured to be opened and closed by sliding movement of the second housing 102.

Referring to FIG. 2, the sliding module 200 includes the guide member 201 and the sliding member 202 and couples the guide member 201 and the sliding member 202 to be slidably movable. And supporting members 213 and guide rods 221, and elastic members 223 and guide wheels 217 for providing driving force as the sliding member 202 moves.

The guide member 201 is mounted to the front upper end of the first housing 101, and the support members 213 are mounted to both side ends thereof. The support members 213 are shaped to surround both side ends of the sliding member 202 and have a slide hole 215 formed to penetrate in the longitudinal direction thereof.

The sliding member 202 is mounted to the seating surface 129 of the second housing 102, and both ends thereof are provided with a pair of fixing members 229 extending in both directions. The sliding member 202 is slidably moved in the longitudinal direction while maintaining a state facing the guide member 201 in a state in which both side ends thereof are covered by the support members 213.

In this case, the fixing members 229 interfere with the supporting members 213 to limit the moving range of the sliding member 202. The support members 213 may be integrally formed with the guide member 201, and in the present embodiment, the support members 213 are mounted and fixed to the guide member 201 by rivets 214.

Both ends of the guide rods 221 are fixed to the fixing members 229, and are spaced apart from both side ends of the sliding member 202. The support members 213 are coupled in a state in which both side ends of the sliding member 202 are wrapped, and thus may interfere with the guide rods 221. In this case, the guide rods 221 are slidably moved through the slide holes 215 of the support members 213 to avoid the interference with the support members 213 while sliding the sliding members 202. Will guide you.

Meanwhile, the support members 213 may be made of synthetic resin such as polyoxymethylene (POM), and the guide rods 221 may be made of a metallic material. This is because the guide rods 221 are long in length compared to their diameters, and only both ends thereof are fixed to the sliding member 202, so that the guide rods 221 are made of a metallic material to secure mechanical strength. In addition, since the support members 213 directly rub against the guide rods 221, the support members 213 may cause a lot of noise when the support members 213 are made of a metallic material. Therefore, the support members 213 are made of a POM material having excellent mechanical strength such as wear resistance and lubricity to secure structural stability and to prevent noise due to friction.

Each of the guide rods 221 may be provided with a damper 225. When the sliding member 202 is completely moved above or below the guide member 201, the damper 225 is interposed between the support members 213 and the fixing members 229 to provide shock and noise. Will alleviate In FIG. 2 for explaining the present embodiment, the damper 225 is illustrated to be configured only at the upper ends of the guide rods 221, but is preferably installed at both ends.

The elastic members 223 and the guide wheels 217 are configured to provide a driving force for moving the sliding member 202.

The pair of elastic members 223 are arranged side by side along the sliding movement direction of the second housing 102, the center portion is curved in a direction away from each other. When an external force is applied to each of the elastic members 223 to deform, the elastic members 223 accumulate elastic forces, and the elastic force accumulated in the elastic members 223 causes the elastic members 223 to be in an initial state. That is, as shown in FIG. 1 or FIG. 2, the center portion acts as a force for restoring the curved shape away from each other.

The guide wheels 217 are rotatably mounted to the guide member 201 by a rotating pin 218, and the sliding member 202 is coupled to the guide member 201 to allow the guide members 223 to rotate. It is supported on the outer surface opposite each other. Referring to FIG. 3, the guide wheels 217 may have grooves formed at the center thereof to surround a portion of the outer circumferential surface of the elastic members 223.

In addition, when the shape of the guide wheel 217 is partially changed, as shown in FIG. 4, the guide wheels 217 may have through holes, and the elastic members 223 may be coupled to pass through the through holes. Can be. Although the elastic members 223 are coupled to penetrate the guide wheels 217, the guide wheels 217 may be rotatably coupled to the guide member 201. This is because when the sliding member 202 is slid, the elastic members 223 are deformed, wherein the direction of the through holes formed in each of the guide wheels 217 is also aligned in the direction in which the elastic members 223 are deformed. Because it must be. That is, when the elastic member 223 is coupled to penetrate the guide wheels 217, as the elastic member 223 is deformed, the through hole may also be aligned with the deformation of the elastic member 223. The guide wheel 217 is rotated so that.

5 to 7 sequentially illustrate the operation of the sliding module 200, and FIGS. 8 to 10 illustrate the opening operation of the portable terminal 100 including the sliding module 200 in sequence. .

5 and 8, the sliding member 202 is positioned below the guide member 201, and the support members 213 are fixed members 229 on top of the sliding member 202, respectively. ) Has been interfered with. In addition, when the sliding member 202 is positioned below the guide member 201, the second housing 102 overlaps the first housing 101 to close the front surface of the first housing 101. Let's go.

In this case, since the elastic members 223 are curved in a shape in which the center portions thereof are farther from each other, the guide wheels 217 maintain the state of being positioned on the upper ends of the elastic members 223. Accordingly, the second housing 102 may also stably maintain the closed state of the first housing 101.

6 and 9, when the user moves the second housing 102 upward to open the first housing 101, the sliding member 202 moves upward of the guide member 201. The guide wheels 217 are gradually moved below the elastic members 223. At this time, since the guide wheels 217 are maintained at a constant interval, the elastic members 223 are gradually deformed, and the center portions thereof approach each other according to the intervals of the guide wheels 217.

Since the elastic force acts on the elastic members 223 in the direction of moving the guide wheels 217 to the upper ends of the elastic members 223, the sliding module 200 until the elastic members 223 are deformed in a straight line. ) Generates a driving force acting in the direction of moving the sliding plate downward.

The second housing 102 also gradually moves upwards of the first housing 101 while the guide wheels 217 deform the elastic members 223 while moving downward of the elastic members 223. The keypad 111 is opened.

When the sliding member 202 and the second housing 102 are moved upward and the elastic members 223 are out of the straight state, the sliding member 202 and the second housing 102 are restored to their initial shape by the elastic force accumulated in the elastic members 223. In this case, as the elastic member 223 is restored to its initial shape, the guide wheels 217 move downward of the elastic members 223 and the sliding member 202 moves upward.

8 and 10 illustrate the sliding module 200 and the terminal 100, respectively, when the guide wheels 217 are completely moved below the elastic members 223. Even when the guide wheels 217 are completely moved to the lower side of the elastic members 223, the elastic members 223 maintain the initial shape, so that the guide wheels 217 and the second housing 102 are further formed. It does not move abnormally and maintains a stable stop state.

On the other hand, the guide wheels 217 is configured to surround a portion of the outer peripheral surface of the elastic member 223, or the elastic member 223 has been mentioned above has a through hole through which it can pass. In the case where the guide wheels 217 respectively cover only a part of the outer circumferential surface of the elastic members 223, when the sliding member 202 slides, the guide wheels 217 rotate so that the guide wheels 217 rotate. And friction between the elastic members 223 can be prevented.

On the other hand, when the elastic member 223 penetrates the guide wheels 217, the inner wall of the through holes formed in the guide hole and the outer circumferential surface of the elastic member 223 directly rub, thereby causing noise and obstacles to operation. You can. Therefore, if the guide wheel 217 is manufactured using a synthetic resin having mechanical properties and lubricity, such as POM, such a friction and the resulting noise, operation disturbances, etc. will be solved.

However, as the sliding member 202 slides, the guide wheels 217 may be manufactured to have a stable structure capable of preventing friction with the elastic members 223 while rotating.

11 is a plan view showing the sliding module 200 of the portable terminal 100 according to another embodiment of the present invention, Figure 12 is a plan view showing the sliding module 200 shown in FIG.

The sliding module 200 according to the present embodiment changes the shape of the elastic members 223, and the position where the guide wheel 217 contacts the elastic member 323 corresponding to the changed shape of the elastic members 323. There is a difference from the previous embodiment in that it changed. Therefore, it should be noted that reference numerals for components that may be easily understood through the preceding embodiments may be given the same or omitted, and detailed description thereof may also be omitted.

As shown in FIGS. 11 and 12, the elastic members 323 of the sliding module 200 according to the present embodiment fix both ends of the sliding module 202 to the sliding member 202, and the distance between the central portions rather than the distance between the ends thereof. The distance is curved closer. In addition, the guide wheels 217 mounted on the guide member 201 are reciprocated between both ends of the elastic members 323 in a state of being supported on inner surfaces of the elastic members 323 facing each other.

When the sliding member 202 slides with respect to the guide member 201, elastic forces are accumulated while the central parts of the elastic members 323 are deformed from each other according to the positions of the guide wheels 217. The elastic force accumulated in each of the elastic members 323 serves as a driving force for moving the guide wheels 217 to either one of both ends of the elastic member 233.

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.

As described above, since the sliding module according to the present invention does not have a component that operates in the space between the elastic members or the guide wheels, the space can be utilized in various ways. For example, conventional sliding modules have many limitations because they have to design a path for wiring a flexible printed circuit by avoiding a space in which the elastic members rotate, but the sliding module according to the present invention has the elastic members or The space between the guide wheels can be utilized to vary the wiring path of the flexible printed circuit. In addition, since the assembly position is determined only by arranging the elastic members next to each other, there is an advantage in that the design and assembly of the sliding module are easy. Furthermore, when the guide wheel rotates while being in contact with a portion of the outer circumferential surface of the elastic members, it is possible to prevent friction when the housings of the terminal slide, thereby preventing noise and smoothly implementing the sliding operation.
