The present invention relates to a portable terminal, and in particular, to minimize the configuration space for the operation of the sliding cover to reduce the thickness of the entire portable terminal, while moving the sliding cover in the vertical direction as well as the left and right, and the left and right sliding type It relates to a cover opening and closing device for a portable terminal and a portable terminal using the same.

In general, a communication terminal may be classified into a wired or wireless communication terminal, and a wired communication terminal is an office or home telephone, and a wireless communication terminal is a PCS, a cellular phone, or a PDA. Wireless communication terminals are commonly referred to as mobile communication terminals or portable terminals because they provide portability and mobility to a user.

Due to the development of the technology, such a portable terminal provides a user with text information, image information, a game, etc., beyond the step of delivering only simple voice information. The type of the mobile terminal is largely a bar type and a flip type with a cover. It can be divided into flip type and folder type.

Folder-type mobile terminal has a structure that can open and close the folder when a call or mobile phone can solve the problem that the length of the bar-type or flip-type mobile terminal, but the hinge portion connecting the upper folder and the lower folder is easily damaged. There is a problem.

In order to solve the problem of such a folding type portable terminal, a sliding type portable terminal in which a folder is moved up and down in a semi-automatic manner in a sliding type with respect to the main body of the portable terminal has been proposed. Most sliding type mobile terminals are opened and closed by semi-automatically sliding the cover with respect to the main body of the portable terminal using the elastic force of the torsion spring.

1 is an exploded perspective view showing a portable terminal including a slide hinge module using a conventional torsion spring, Figure 2 is a perspective view showing a slide hinge device shown in FIG.

1 and 2, a conventional portable terminal includes a main body 10 having a predetermined length, a cover 20 slidably coupled to the main body 10, and the cover 20 with the main body. And a slide hinge module (30) which slides with respect to (10) semi-automatically. In the conventional mobile terminal, when the user pushes the cover 20 upward, the cover 20 is manually moved to a predetermined position with respect to the main body 10, and when the user passes the predetermined position, the torsion of the slide hinge device 30 is performed. The cover 20 is designed to open while automatically sliding by the elastic restoring force accumulated in the spring 36.

The torsion spring type slide hinge module 30 will be described in more detail as follows. The slide hinge module 30 is installed on the guide rail 31 installed on the front of the main body 10 and the back of the cover 20 and inserted into the guide rail 31 to move up and down along the guide rail 31. A torsion spring 36 which is connected between the moving guide member 34 and the guide rail 31 and the guide member 34 to provide elastic force for the guide member 34 to move semi-automatically along the guide rail 31. It consists of.

At this time, the guide rail 31 is a pair of rails 32 which are installed at a predetermined interval in the longitudinal direction of the main body 10 on the front surface of the main body 10, and the middle connecting the middle portion of the rail 32 The frame 33 is provided. That is, the guide rail 31 has a shape similar to the letter "H". In addition, since the cover 20 moves up and down in the longitudinal direction of the main body 10, the rail 32 of the guide rail 31 is formed in the longitudinal direction of the main body 10.

On both sides of the guide member 34, the guide part 35 inserted into the rail 32 is guided and bent, and has a rectangular plate shape covering the guide rail 31 as a whole.

One end of the torsion spring 36 is fixed to the lower end of the center of the intermediate frame 33, the other end is fixed to the guide member 34 close to the rail 32 on one side. Therefore, when the guide member 34 moves up and down along the guide rail 31, the torsion spring 36 opens and closes the cover 20 while repeating compression and tension.

Hereinafter, a method of opening and closing the cover 120 of the portable terminal including the slide hinge module 30 of the conventional torsion spring method will be described with reference to FIGS. 3 and 4. 3 is a perspective view illustrating a state in which the cover is closed in the portable terminal of FIG. 1, and FIG. 4 is a perspective view illustrating a state in which the cover is opened in the portable terminal of FIG. 1. Here, the method of closing and opening the cover 20 will be described based on the method of opening the cover 20 because only the operation proceeds in the opposite manner and proceeds on the same principle.

When the cover 20 is closed to the main body 10, as shown in FIG. 3, the guide member 34 is positioned below the middle frame 33 of the guide rail 31. When the cover 120 is pushed upward with respect to the main body 10 in this state, as shown in FIG. 4, the guide member 34 moves upward along the guide rail 31 to open the cover 120.

In detail, when the user pushes the cover 20 upward, the torsion spring 36 is compressed and the guide member 34 moves along the guide rail 31. At this time, the elastic force is accumulated in the torsion spring (36). While moving in this way, when both ends of the torsion spring 36 are beyond the most compressed section, the guide member 34 is automatically moved along the guide rail 31 by the elastic force accumulated in the torsion spring 36. In other words, the cover 20 is opened. That is, if the cover 20 is manually pushed upwards slightly when both ends of the torsion spring 36 are horizontal, then the cover 20 is automatically raised by the elastic force accumulated in the torsion spring 36 thereafter. It rises and opens.

On the contrary, when the cover 20 is closed, the cover 20 is pulled a little lower than when both ends of the torsion spring 36 are horizontal, and then the cover 20 has the elastic force accumulated in the torsion spring 36 thereafter. It will automatically descend and close by.

However, such a conventional sliding type mobile terminal has a structure in which only a part of the front surface of the main body exposed by moving the cover upward with respect to the main body in a vertical sliding manner has a problem in that the utilization of the front surface of the main body is inferior. Holding it.

In addition, the conventional slide hinge module of the torsion spring method occupies most of the installation space formed between the main body and the cover to form the length of the cover is opened and closed. This is a problem that acts as a significant space constraint when embedding parts such as a printed circuit board in the body.

In addition, in order to lengthen the sliding length (pitch), both ends of the torsion spring must be longer, which means that the area occupied by the slide hinge module becomes larger, so that there is a significant limitation in use in a portable terminal where miniaturization is important.

In addition, the conventional torsion spring slide hinge module has a guide rail and the guide member is coupled to each other and the torsion spring is inserted and fixed between them to perform a sliding operation, the thickness of the mobile terminal is thicker than the general folding portable terminal problem Is holding.

Hereinafter, the racks 300 and 600, the pinion 400 and the guide part 700 will be described in detail.

FIG. 10 is a perspective view illustrating the pinion of FIG. 7 engaged with a rack, and FIG. 11 is an enlarged view showing an enlarged portion "A" of FIG.

As shown in Figure 10 and 11, the rack (300, 600) is fixedly installed in the longitudinal direction perpendicular to the one side edge of the rear top of the sliding cover (200). The present invention discloses an example in which the racks 300 and 600 are installed at the upper left corners. The rack (300, 600) is provided with at least the length in consideration of the distance to which the sliding cover 200 is to be moved. In addition, the rack (300, 600) is toothed toward the direction in which the pinion 400 is installed is meshed with the pinion (400). The material of the racks 300 and 600 may be light and synthetic resin-based, which may reduce the occurrence of noise without severe wear when interacting with the pinion 400.

The racks 300 and 600 are vertical racks 300 installed vertically at one side edge of the rear side of the sliding cover 200 and horizontal racks installed at the left and right lengthwise sides at one edge of the sliding cover 200 ( 600). At this time, both ends of the vertical rack 300 and the horizontal rack 600 located at one edge of the sliding cover 200 are spaced to engage the pinion 400 located at the corner of the main body 100. It is fixedly installed.

The pinion 400 is installed in the main body 100 so as to be engaged with the racks 300 and 600 and transmits a driving force while rotating (rotating) between the rack 300 and the pinion driving means 500. do. As will be described later, the pinion 400 rotates one rotation (rotation) during one stroke of the pinion driving means 500. Therefore, the circumferential length of the pinion 400 corresponds to a one-way movement distance for opening and closing of the sliding cover 200. Accordingly, a pinion 400 of an appropriate size considering the moving distance of the sliding cover 200 should be provided. The pinion 400 is also preferably provided with the same material as the rack 300 for the same reason.

At this time, the pinion 400 not only moves up and down along the vertical rack 300, but also moves left and right along the horizontal rack 600. Of course, if the pinion 400 moves along either one of the vertical rack 300 or the horizontal rack 600, the other side may not move.

The teeth 310 on one side of the teeth formed at the point where the vertical rack 300 and the horizontal rack 600 intersect with the gear blade of the pinion 400 and the teeth 610 on the other side of the pinion 400 Gear blades are formed in contact. That is, since the pinion 400 has a structure in which a gear blade is formed on an outer circumferential surface in the form of a disc, when the pinion 400 meshes with the teeth of both ends of the vertical rack 300 and the horizontal rack 600 installed at right angles, the vertical rack 300 Or horizontal rack 600 cannot be moved. Accordingly, in the present invention, the tooth 310 of the end is formed in the same manner as the other teeth so that the pinion 400 can be engaged with the tooth 310 of the end of the vertical rack 300 to form the vertical rack 300. Form. The tooth 610 of the end is shaved so that the gear blade of the pinion 400 can be engaged from the tooth following the tooth 610 of the end of the horizontal rack 600. Accordingly, when the pinion 400 moves to the left along the horizontal rack 600, the pinion 400 rotates while being engaged from the tooth next to the tooth 610 at the end of the horizontal rack 600.

In addition, the guide part 700 is a part for guiding the movement of the pinion 400 moving along the racks 300 and 600, and is installed at the rear of the sliding cover 200, and the racks 300 and 600. And a guide rail 710 installed in parallel with the guide rail and a guide 720 installed on the front surface of the main body 100 to move along the guide rail 710.

At least one guide rail 710 is installed on the rear surface of the sliding cover 200, in the present invention was formed in a groove shape. The guide 720 is inserted into the guide rail 710 having a groove shape and moves along the guide rail 710. For example, the guide rail 720 may be formed as an English letter "L" shaped groove corresponding to the rack (300, 600).

For example, the guide rail 710 is installed in parallel to the vertical rack 300, the vertical guide rail 712 for guiding the vertical movement of the sliding cover 200, and connected to the upper end of the vertical guide rail 712, horizontal Installed parallel to the rack 600 includes a horizontal guide rail 714 for guiding the left and right movement of the sliding cover 200.

In the exemplary embodiment of the present invention, an example in which two guide parts 700 are formed is disclosed, but the present invention is not limited thereto and only one may be formed.

The pinion drive unit 500 is provided to provide rotational force to the pinion 400. That is, the pinion driving means 500 provides a rotational force in a direction in which the sliding cover 200 is closed within a predetermined distance, and serves to provide a rotational force in a direction in which the sliding cover 200 is opened outside a predetermined distance. do.

Thus, the configuration of the pinion driving means 500 will be described in more detail.

12 is a combined perspective view of the pinion and the pinion drive means according to the present invention, Figure 13 is an exploded view of the pinion and pinion drive means according to the present invention.

12 and 13, the pinion drive means 500 according to the present invention, the tube 510, the sliding cam 520, the acting cam 530, the compression spring 540 and the mating And a shaft 550. Here, the sliding cam 520 and the actuating cam 530 is a cam means for converting the elastic force of the compression spring 540 to the rotational force to transmit to the pinion 400.

First, referring to the overall configuration of the pinion driving means 500, the sliding cam 520, the actuating cam 530 in the receiving space in the tube 510 of a small size that is inserted and fixed to the main body 100 And a compression spring 540 is inserted and installed in a dense state. In addition, the components 520, 530, and 540 may be seen to be penetrated and supported by the matching shaft 550 for stable operation and mutual registration. Hereinafter, the components will be described in detail.

The tube 510 is a cylindrical container having a receiving space therein, one side of which is in contact with the pinion 400 is opened, and the other side of the tube 510 is formed with a through hole in which the end of the mating shaft 550 is rotatably supported. Such a tube 510 is small enough that most of the body is inserted into the main body 100, but the sliding cam 520, the actuating cam 530, the compression spring 540 and the mating shaft 550 are different without interference. Provides an isolated compartment that protects the components from being disturbed.

The sliding cam 520 is installed to linearly reciprocate in the axial direction of the pinion 400 in the tube 510. At this time, the sliding cam 520 is formed in the outer circumferential cross-section is slightly rounded in a circular shape so that linear movement is possible but does not rotate, the outer circumferential surface in the space in the tube 510 to which the sliding cam 520 reciprocates A predetermined step is formed over the angular portion. Meanwhile, the profile of the sliding cam 520 is formed of a top dead center 520b, a bottom dead center 520c, and an inclined line 520d connecting the top dead center 520b and the bottom dead center 520c along the circumferential direction.

The actuating cam 530 is installed in the tube 510 such that the profile is in contact with the profile of the sliding cam 520 while being fixed to the pinion 400. In this case, the profile of the actuating cam 530 is a bottom dead center 530c of a shape corresponding to the top dead center 520b, the bottom dead center 520c and the inclined line 520d of the sliding cam 520 profile. And a top dead center 530b and an inclined line 530d. By this configuration, the actuating cam 530 transmits the rotational force to the pinion 400 while rotating in the linear movement of the sliding cam 520, which will be described in detail later. Here, it is preferable that the actuating cam 530 is integrally formed with the pinion 400 from the time of manufacture, thereby making the coupling more stable while reducing the number of parts.

The compression spring 540 is installed while being fitted to the outer circumferential surface of the mating shaft 550 at the innermost side of the tube 510 to push the sliding cam 520 toward the actuating cam 530 with its own elastic force. . As a result, the elastic force of the compression spring 540 is converted into rotational force through the sliding cam 520 and the actuating cam 530 constituting the cam means to act on the pinion 400.

The mating shaft 550 includes the pinion 400, the actuating cam 530, and the sliding cam so that the actuating cam 530 and the sliding cam 520 are matched with each other in the tube 510. 520 and the other end of the tube 510 are installed through. To this end, the other end of the actuating cam 530, the sliding cam 520 and the tube 510 is formed through holes 530a, 92a, 91a to facilitate the passage of the mating shaft 550, respectively. In addition, at the other end of the matching shaft 550 protruding from the other end of the tube 510, a separation preventing piece 560 is provided to prevent separation of the matching shaft 550.

Meanwhile, in the present embodiment, the pinion 400 and the pinion driving means 500 are installed in the main body 100, and the racks 300 and 600 are installed in the cover 200, but the pinion 400 depends on the design conditions. ) And the pinion driving means 500 may be installed in the cover 200, and the racks 300 and 600 may be installed in the main body 100.

Such a method of opening and closing the sliding type portable terminal according to the present invention will be described with reference to FIGS. 14A to 14D. 14A to 14F are reference views for explaining the opening and closing operation of the sliding type portable terminal according to the present invention.

Similarly, in order for the sliding cover 200 to be closed in an open state in the upward direction, a user's force may be applied in a direction in which the sliding cover 200 is closed in the state of FIG. 14E. At this time, the rack 300 and the pinion 400 is moved and rotated in the opposite direction, the pinion drive means 500 resists the force to close the sliding cover 200 until the transition point and the transition point When it passes, it will act in the same direction to close the sliding cover 200. Detailed description thereof will be omitted since it is substantially the same as when the sliding cover 200 is opened.

Next, the operation in which the sliding cover 200 moves to the left will be described in detail with reference to FIG. 14F. When the user slides the sliding cover 200 to the left side, the horizontal rack 600 fixed to the rear side of the sliding cover 200 is described. ) Rotates the engaged pinion 400 while moving to the left. In addition, the horizontal guide rail 714 is moved to the left along the guide 720.

 At this time, the pinion driving means 500 resists a force to close the sliding cover 200 until the transition point, and when the transition point passes, the sliding cover 200 acts in a direction to move to the left side. Detailed description thereof will be omitted since it is substantially the same as when the sliding cover 200 is opened upward.

When the sliding cover 200 is completely opened to the left side with respect to the main body 100, the keypad 110 on the front right side of the front surface of the main body 100 exposed by the sliding cover 200 is exposed to the outside.

In particular, if the frame 800 is formed in a shape and size that fits well with the sliding cover 200, it is easier to install.

When the pinions 450 and 460 and the racks 350 and 650 are deformed in this manner, the first pinion 450 is engaged with only the vertical rack 350 for vertical movement of the sliding cover 200 and the second pinion ( 460 is engaged only with the horizontal rack 650 for the horizontal movement of the sliding cover 200. Accordingly, while varying the sizes of the first pinion 450 and the second pinion 460, the number and the moving distances of the transition points are different from each other when the sliding cover 200 is vertically opened and closed. You can. Therefore, unlike before the deformation was provided with only one pinion, the uniformity between the vertical opening and closing operation of the sliding cover 200 and the left and right opening and closing operation disappears, it is possible to give a variety to suit your taste.
