The present invention relates to a mobile communication terminal, and more particularly, to a mobile communication terminal that is slim, simple to assemble and disassemble, and improves workability.

In general, a mobile communication terminal is a device capable of communicating wirelessly while moving, and is generally referred to as a mobile phone or a PDA. Such mobile communication terminals include flip type, folder type, slide type, and the like.

The folding terminal usually includes a main body having a plurality of key buttons for signal generation and information input on a front surface thereof, and a hinge portion formed on an upper end thereof; It consists of a folder which is pivotally opened and closed around the hinge portion and has a display portion for displaying various menus and information on one or both surfaces. These clamshell terminals are used when the phone is open, the message is sent, or when the user wants to use the wireless Internet. The folder is open when the display is exposed. Compared to the portability.

However, since the folding type terminal is opened and closed by a strong elastic force around the hinge portion, there is a problem in that both hands must be used to open the folder.

In order to solve this problem, recently, a slide type terminal provided with a display unit sliding with respect to the main body in a state where the main body and the display unit are coupled in parallel has been released. In addition, as the DMB (Digital Multimedia Broadcasting) era opens, a slide swing type terminal capable of swinging the display part about 90 degrees in addition to the slide type terminal has been released according to a consumer's demand for watching a wider screen. .

1 and 2 are side cross-sectional views for explaining a conventional mobile phone is sliding, Figure 3 is a front view for explaining a conventional mobile phone is swinging. As shown in these figures, the conventional mobile phone 101 includes a main body 110 in which a main board (not shown) is embedded; A display unit 120 disposed on the front surface of the main body 110, the image unit 121 having an image formed thereon, and a casing 122 surrounding the image unit 121; A slide hinge 130 installed between the main body 110 and the display 120 to slide the display 120 relative to the main body 110; The swing hinge part 140 is provided between the image part 121 and the casing 122 to swing the image part 121 with respect to the casing 122.

That is, the slide hinge 130 is assembled to the back of the display 120 and the front of the main body 110, the swing hinge 140 is a support bracket 160 between the image portion 121 and the casing 122. ) Is assembled. Therefore, in order for the support bracket 160 and the slide rails 132 to be firmly coupled to the front and rear surfaces of the casing 122, the strength of the casing 122 is required to some extent. For this purpose, the strength is generally increased by increasing the thickness. Secured. For this reason, since the thickness of the mobile phone 101 becomes overall thick, there is a limit in implementing a slim structure.

In addition, since the sliding hinge 130 and the swing hinge 140 must be assembled and disassembled separately, there is a problem in that workability is degraded.

4 is a side cross-sectional view of a mobile phone according to an embodiment of the present invention, FIG. 5 is a side cross-sectional view showing a state in which the display unit of FIG. 3 is slid relative to the main body, and FIG. 6 is a display of the mobile phone according to an embodiment of the present invention. It is a front view which shows the state which swinged with respect to the addition main body. As shown in these figures, the mobile phone 1 according to the present invention comprises a main body 10; A display unit 20 connected to the main body 10 to form an image; A slide hinge unit 30 provided between the main body 10 and the display unit 20 to slide the display unit 20 with respect to the main body 10; A swing bracket 40 coupled with a partial configuration of the slide hinge portion 30 to swing the display portion 20 with respect to the main body 10; It is coupled to the swing bracket 40 includes a support bracket 60 for supporting the swing bracket 40.

In the main body 10, a main board (not shown) mounted with various chips for driving the mobile phone 1 is provided. The lower end of the main body 10 is provided with a key operation unit (not shown) in which an alphanumeric key is arranged, and the upper end of the key operation unit is formed in a substantially rectangular plate shape and has a rail 32a to be described below. Is equipped.

The display unit 20 is disposed in front of the main body 10 so as to be substantially parallel to the main body 10, and the image portion 21 on which the image is formed and the casing 22 forming the appearance of the image portion 21 are formed. It is made to include.

The image part 21 is driven by a liquid crystal element, and is provided in the shape whose longitudinal length is longer than the horizontal length.

The casing 22 is formed to penetrate an image coupling portion 43 (see FIG. 7) to be described later, and a slider 31 to be described later, which is guided and moved by a slide rail 32 to be described later.

As shown in FIGS. 7 to 9, the slide hinge portion 30 is a slider 31 coupled to the rear surface of the casing 22 and a slide coupled to the front surface of the main body 10 to guide the slider 31. Rail 32. At this time, a pair of torsion springs 75a and 75b having one end coupled to the slider 31 and the other end coupled to the slide rail 32 are coupled between the slide rail 32 and the slider 31.

The slide rail 32 is press-made and provided in the shape longer than the slider 31 in the longitudinal direction. In the present invention, the slide rail 32 is installed on the main body 10 and the slider 31 is installed on the display unit 20, but the slide rail is installed on the display unit and the slider may be installed on the main body as in the prior art. have. However, it is more advantageous in reducing the thickness of the mobile phone 1 when it is coupled to the main body 10 side than when the elongated slide rail 32 is coupled to the display unit 20 side. That is, if the long slide rail 32 is coupled to the display unit 20 side and the slider 31 is coupled to the main body 10 side, the area equal to the length of the slide rail 32 is invalid, but the slide rail When the 32 is coupled to the main body 10 side and the slider 31 is coupled to the display unit 20 side, it does not occupy an area up to the lower region of the display unit 20, so that the thickness of the area is slim. It is advantageous. In addition, the slider 31 and the support bracket 60 to be described later are integrally manufactured by the die casting method, and the display unit 20 is coupled to the display unit 20 to produce the slide rail 32 and the support bracket 60 to be described later by the die casting method. The structure is simpler than that. Therefore, it is excellent in productivity that the slider 31 is attached to the display part 20, and the slide rail 32 is attached to the main body 10. FIG.

One end of the torsion springs 75a, 75b moves integrally when the slider 31 moves, and the other end is fixed integrally with the slide rail 32 and is arranged in a substantially parallelogram shape. Therefore, when the slider 31 is pushed upward as shown in FIG. 5, the pair of torsion springs 75a and 75b have a torsional repulsive force acting while the parallelogram shape is changed, and the slider 31 crosses the threshold line. Under the action of the mask torsion repulsive force is naturally pushed to the upper side of the slide rail (32). The semi-automatic principle of the slide hinge portion 30 is not limited to this, and may be any type that slides within a known range.

The swing bracket 40 is provided in a circular shape and is coupled to the rear surface of the image portion 21 so as to swing the image portion 21 with respect to the casing 22. The swing bracket 40 includes a swing portion 41 which rotates integrally with the image portion 21 and a guide portion 42 which guides the swing portion 41 so that the swing portion 41 can rotate.

The swing portion 41 is formed to be stepped from the image coupling portion 43 and the image coupling portion 43 coupled to the rear surface of the image portion 21 and frictionally contacts the guide portion 42 when the image portion 21 is rotated. It includes a contact portion 44. On the lower side of the swing portion 41, a washer 48, which frictionally contacts the bottom surface of the contact portion 44 when the swing portion 41 rotates, is seated on the support bracket 60. Therefore, when the image portion 21 rotates, the swing portion 41 can be rotated by the frictional force between the pressing portion 45 and the washer 75 of the guide portion 42.

The image coupling part 43 is provided with a plurality of screw fastening holes 43a to which screws (not shown) are coupled to the image part 21 and the swing part 41. Thus, the image part 21 may be integrally coupled with the swing part 41 to rotate with the swing part 41 about the swing axis 50.

The guide portion 42 includes a pressing portion 45 for pressing the upper surface of the contact portion 44, and a casing coupling portion 46 formed to be stepped from the pressing portion 45 and coupled to the rear surface of the casing 22. do.

The casing coupling portion 46 is formed with a plurality of screw through holes 46a through which the screws 61 for coupling the guide portion 42 to the rear surface of the casing 22 are formed. Accordingly, the guide part 42 is fixed to the casing 22 integrally to support the swing part 41 so as to be rotatable.

The support bracket 60 is preferably formed integrally with the slider 31 and has a strength sufficient to support the slider 31 and the swing bracket 40, respectively. Since the swing bracket 40 is coupled to one side of the support bracket 60 and the slider 31 is coupled to the other side, the conventional swing hinge 140 and the slide hinge 130 are spaced apart from each other. The thickness of the mobile phone 1 can be reduced compared to the structure that is separately coupled in a state. Here, the support bracket 60 is integrally coupled with the guide portion 42 is fixed to the back of the casing 22. To this end, a boss 61 is formed in the support bracket 60 to communicate with the screw through hole 46a of the casing coupling part 46 to form a screw coupling hole 60a to which the screw 61 is coupled. On the other hand, the support bracket 60 is coupled to the mounting groove 63, the plate 55 to which the coil spring 56 is coupled.

The plates 55 are provided in pairs and disposed to face each other, and are mounted in mounting grooves 63 formed in the support bracket 60, respectively. Accordingly, when the swing portion 41 rotates about 30 degrees (when the image portion 21 rotates), the operation protrusions (not shown) formed on the bottom surface of the swing portion 41 are caught by the pair of plates 55. The plate 55 is pushed outwards, whereby the coil spring 56 is compressed while the repulsive force is generated. Therefore, when the swing portion 41 exceeds 30 degrees, the swing portion 41 may be smoothly rotated to approximately 90 degrees by the repulsive force of the coil spring 56.

Here, the support bracket 60 is preferably manufactured integrally with the slider 31 and the die casting method. Thus, productivity and workability may be improved as compared with the method of separately manufacturing and supporting the support bracket 60 and the slider 31.

Here, the mobile phone 1 preferably further includes a camera 70 provided at the upper end of the main body 10 to photograph the subject. That is, when the camera 170 is provided in the display unit 120 as in the related art, since the center of gravity is located at the upper portion of the mobile phone 101, the user 110 slides the display unit 120 upward. It is difficult to press a letter or numeric key provided at the bottom of the, but when the camera 70 is provided in the main body 10 as in the present invention, because the center of gravity of the main body 10 is to slide the display unit 20 upward Even when the body 10 naturally moves downward due to its own weight, it may be convenient to press a letter or numeric key.

By such a configuration, a brief description of the principle that the display unit 20 of the mobile phone 1 according to the present invention is sliding and swinging with respect to the main body 10 as follows.

When the user presses the display unit 20 upward to make a call or transmit a message, the slider 31 mounted on the back of the casing 22 moves upward along the slide rail 32 mounted on the main body 10. It becomes a usable state. In this process, the pair of torsion springs 75a and 75b have a torsion repulsive force acting while the parallelogram shape is changed, and when the slider 31 crosses a critical line, the torsion repulsive force naturally acts as the slide rail 32. It will be pushed upwards.

On the other hand, when the user rotates the image portion 21 by a predetermined angle (about 30 degrees), the image portion 21 is rotated to about 90 degrees smoothly and semi-automatically about the swing axis 50. That is, when the swing portion 41 is rotated by about 30 degrees (when the image portion 21 rotates), the operation protrusion (not shown) formed on the bottom surface of the swing portion 41 is caught by the pair of plates 55. Push the 55 in the outward direction and thereby the coil spring 56 is compressed to generate a repulsive force. Therefore, when the swing portion 41 exceeds 30 degrees, it can be smoothly rotated to approximately 90 degrees by the repulsive force of the coil spring 56.

In the above-described embodiment, the image portion is provided to swing about 90 degrees, but is not limited thereto and may be variously implemented within a range of 0 to 360 degrees.

As described above, according to the present invention, a mobile communication terminal having a slim, simple assembly and disassembly and improved workability is provided by integrally forming a part of the slide hinge portion and a support bracket.
