Description

Hinge MODULE FOR SLIDE OPEN TYPE PORTABLE TERMINAL AND PORTABLE TERMINAL}

The present invention relates to a mobile terminal, and in particular, to minimize the overall thickness, a slim, smooth operation and structural stability is ensured, the assembly is further improved hinge module and portable terminal for open type portable terminal.

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 usually called mobile communication terminals or portable terminals because they provide portability and mobility to users.

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 audio 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.

The folding portable terminal has a structure that can open and close the folder when calling or carrying, so it can solve the problem that the length of the bar or flip portable terminal is long, but the hinge portion connecting the upper folder and the lower folder is easily damaged. Has a problem.

In order to solve the problem of the folding type portable terminal, a slide open type portable terminal in which the cover is opened and closed while the cover is slid up and down by the semi-automatic body has been proposed.

Such a slide open type portable terminal has been equipped with a hinge module that semi-automatically opens and closes the cover by using the elastic force of the torsion spring, but recently, unlike the torsion spring, the coil spring has almost no elastic force even after long-term use. Hinge modules of the type used have been developed and installed.

1 is an exploded perspective view for explaining a hinge module for a slide open type portable terminal according to the prior art.

As shown, the hinge module for a conventional slide open type portable terminal has a base 20 fixed to the main body of the portable terminal, a mount 30 fixed to the cover, and a mount 30 with respect to the base 20. It was composed of a stretchable bar assembly 10 for imparting elastic force while coupling the two to be opened and closed by sliding movement.

In the conventional hinge module, the elastic bar assembly 10 is installed between two T-shaped elastic bars 11 and 12 intersected in two stages and the two elastic bars 11 and 12 to increase the overall length. It was provided with a tension spring (13) acting so that. As a result, when the length of the elastic bar assembly 10 is minimized, the force is provided in a direction opposite to the opening and closing of the cover within a distance not passing the transition point, and the cover is moved from the distance past the transition point. The cover was opened semi-automatically by providing a force in the same direction to be opened and closed.

However, in the prior art, since the hinge module uses a coiled spring, unlike the torsion spring, the hinge module has an advantage that the elastic force is hardly reduced despite long-term use, but still has many problems to be solved.

That is, in the conventional hinge module, since the two elastic bars 11 and 12 have a stacking section intersecting in two stages, there is a structural limitation in minimizing the thickness. Therefore, a loss width of at least 0.9 [mm] is generated due to the stacking section, and this drawback is inevitably a problem in view of the trend of the recent portable terminal market in which ultra-slimization has become one flow.

In addition, the two elastic bars (11, 12) simply provided in a cross shape is easy to dismantle due to lack of bonding between each other, the reliability of the stable operation when opening and closing the cover was low.

In addition, the end of the spring coil (13A, 13B) to the fastening holes (11B, 12B) formed in the expansion bar (11, 12) for coupling between the expansion bar (11, 12) and the tension spring (13). It was to be hung, but this forced the construction to rely on manual labor, resulting in more labor and labor costs.

In addition, the coupling between the extension bars 11 and 12 and the tension springs 13 is easy to be released during use of the mobile terminal, so that the opening and closing capability of the cover is poor, and thus, between the extension bars 11 and 12 and the tension springs 13. The loosening of the bonds resulted in catastrophic loss of complete cover loss.

In addition, for assembling the elastic bars 11 and 12, the base 20, and the mount 30, the ends of the elastic bars 11 and 12 are drilled to provide through holes 11A and 12A, respectively. The base 20 and the mount 30 were drilled to prepare fastening holes 21 and 31 corresponding to each other, and then fastened and assembled by rivets 42 and 43, respectively. This resulted in an increase in thickness of at least 0.1 mm.

As shown, the present invention is a slide open type portable terminal in which the cover (C) is semi-automatic sliding opening and closing with respect to the main body (B), the main body (B) and the cover (C) to be slidable therein. A hinge module A is installed to couple and provide an elastic force for the semi-automatic of the cover C. The present invention is configured to minimize the thickness of the spring assembly included in the hinge module (A) to slim the entire product and at the same time ensure a smooth opening and closing operation and structural stability of the cover, while improving the assembly between parts. .

Hereinafter, the configuration of the mobile terminal according to the present invention will be described in detail with reference to the hinge module (A).

3 is a partially exploded perspective view of the hinge module of the present invention according to the first embodiment, Figure 4 is an exploded perspective view of the spring assembly of Figure 3 disassembled.

As shown, the hinge module of the present invention includes a base plate 200, a mount plate 300, a guide frame 110, a slider 120, and a tension spring 130 constituting the spring assembly 100. It is configured by.

Here, the spring assembly 100, which plays a pivotal role in providing an elastic force for semi-automatic opening and closing of the mobile terminal cover, is composed of a combination of a guide frame 110, a slider 120, and a tension spring 130. Due to the unique configuration in which the slider 120 and the tension spring 130 are located in the inner space 117 of the guide frame 110, the parts are not overlapped with each other and are formed in only one end.

The present invention is to ensure the slimming, smooth operation and structural stability of the hinge module 100 or the entire portable terminal adopting the same by the unique configuration of the spring assembly 100. Hereinafter, each of the above components will be described.

The base plate 200 is provided in a relatively small size that can be fixed to the front surface of the main body without interfering with the keypad of the mobile terminal. On the left side and the post of the base plate 200, a "c" shaped rail 210 bent in the front for coupling with the mount plate 300 is formed along the vertical direction.

In addition, the front edge of the base plate 200 is provided in the form of protruding the first engaging projection 230 is supported by the first coupling piece 111 that belongs to the guide frame 110. Here, the first engaging projection 230 is formed in a wider end portion of the narrow waist portion 231 and the waist portion 231 is sandwiched so that the first coupling piece 111 is rotatable the first coupling piece It consists of a head portion 232 to prevent the separation of (111). When the first locking protrusion 230 is integrally formed on the base plate 200, the assemblability with the spring assembly 100 is improved, which will be described in detail later with reference to the guide frame 110.

The mount plate 300 is fixed to the back of the cover of the mobile terminal. The mount plate 330 is provided with a size sufficient to maintain the state coupled to the base plate 200 when opening and closing the cover for the main body of the mobile terminal. On the left side and the post of the mount plate 300, a “b” shaped sliding piece 310 is inserted along the rail 210 of the base plate 200 along the vertical direction. As a result, when the cover is opened and closed, the mount plate 300 is slid up and down while maintaining a coupled state with respect to the base plate 200 fixed to the main body. In addition, the mount plate 300 is formed with a dome-shaped receiving portion 320 to accommodate the spring assembly 100.

In addition, the mounting plate 300 is also provided integrally with a second locking projection 330, such as the first locking projection 230. In the case of the second catching protrusion 330, the second coupling piece 123 belonging to the slider 120 is formed to be wider at the end of the waist portion 331 and the waist portion 331, and the second coupling piece 123 is fitted. It consists of a head portion 332 to prevent the separation of the two coupling pieces (123). When the second locking protrusion 330 is integrally formed on the mount plate 300, the assemblability with the spring assembly 100 is improved, which will be described in detail later with reference to the slider 120.

 The guide frame 110 forms a spring assembly 100 together with the slider 120 and the tension spring 130 to maintain the coupling between the base plate 200 and the mount plate 300 and provide spring elastic force thereto. It plays a role. To this end, the guide frame 110 is composed of a rectangular frame or a frame having a rectangular inner space 117 as a whole, integrally the first ring piece 111 of the C ring shape protruding outward in the center of the tip portion thereof. Equipped. The first coupling piece 111 of the C-ring type has a recessed groove 111A having a recessed shape to stably surround the first locking protrusion 230 provided in the base plate 200. As a result, by simply hanging the first coupling piece 111 on the first locking protrusion 230, the base plate 200 is stably coupled. Therefore, in the present invention, using a separate fastening means such as rivets for the coupling between the spring assembly 100 and the base plate 200 does not require a lot of hand assembly work.

In addition, a pair of guide rods 115 are installed at the left side and the post of the inner space 117 of the guide frame 110 to guide the slider 120 to slide smoothly. The guide rod 115 is provided with a solid or hollow circular cross section so as to reduce friction with the slider 120 and improve slip performance. A plurality of through-holes 113 are formed in the rear end portion 110B of the guide frame 110 so that the slide bar 125, which belongs to the slider 120 and moves together, is guided through.

The slider 120 is hinged to the mount plate 300, and installed in the inner space 117 of the guide frame 110 so that the slider 120 can move forward and backward according to the opening and closing of the cover.

To this end, the slider 120 has a guide hole 121 through which the guide rod 115 is slidably fitted. As a result, the slider 120 accurately moves along the trajectory of the guide rod 115 in the inner space 117 of the guide frame 110.

In addition, a slide bar 125 and a second coupling piece 123 are provided for coupling the slider 120 and the mounting plate 300. The slide bar 125 is installed to slidably penetrate the through hole 113 formed in the center of the rear end portion 110B of the guide frame 110, the front end portion thereof is coupled to the slider 120. The second coupling piece 123 is coupled to the rear end of the slide bar 125, but is manufactured in a state coupled from the beginning by insert injection. The second coupling piece 123 is formed in the shape of a C ring. As described above, the second coupling piece 123 formed in the form of a C ring includes a locking groove 123A having a concave shape that stably surrounds the second locking protrusion 330 provided in the mount plate 300. As a result, simply engaging the second coupling piece 123 to the second locking protrusion 330 makes the coupling with the mount plate 300 stable. Therefore, in the present invention, using a separate fastening means such as rivets for the coupling between the spring assembly 100 and the mounting plate 300 does not require much assembly work at all, and increases the thickness of the rivet by 0.1mm This can be reduced.

The tension spring 130 is installed in the inner space 117 of the guide frame 110 serves to give an elastic force between the guide frame 110 and the slider 120. The tension spring 130 is provided in a coil shape. This is because the coil type spring has an advantage that the elastic force is not easily weakened even when used for a long time compared with the torsion spring. In addition, one end and the other end of the tension spring 130 is coupled to the rear end 110B and the slider 120 of the guide frame 110, respectively. At this time, one end and the other end of the tension spring 130 is made of a hook shape and coupled to the guide frame 110 and the slider 120 is inserted by insert injection. As such, when both ends of the tension spring 130 are coupled to the guide frame 110 and the slider 120 by insert injection, their coupling properties are firm and are not easily separated. The thickness corresponding to the iron core can be reduced. In addition, the tension springs 130 are disposed in the same number on the left side and the post in the inner space 117 of the guide frame 110, respectively. As a result, a uniform elastic force can be provided to the slider 120 at the left side and the postal side, thereby preventing a phenomenon in which the elastic force of the spring is excessively biased to either side when the cover of the mobile terminal is opened and closed.

In this case, an alternative configuration may be provided in which the compression spring is provided in place of the tension spring 130 and is installed between the tip portion 110A of the guide frame 110 and the slider 120 in the inner space 117 (later on). Detailed). However, in the case of the replaced configuration, there is almost no difference in the operation of the spring assembly 100, but because the deflection phenomenon occurs when the compression spring is contracted, it is inevitable to consider the design such as increasing the mounting space.

The operation of the hinge module for a slide open type portable terminal according to the present invention configured as described above will be described with reference to FIGS. 5A to 5C.

First, FIG. 5A illustrates a hinge module in an initial state in which a cover C is closed with respect to the main body B of the portable terminal. Therefore, the mount plate 300 fixed to the cover C is biased downward with respect to the base plate 200 fixed to the main body B.

At this time, since the first locking protrusion 230 and the second locking protrusion 330, which are the supporting points of the spring assembly 100, are positioned in the diagonal direction with the largest distance from each other, the spring assembly 100 is in a relaxed state. have. However, the spring assembly 100 still tends to stretch because the tension spring 130 provides elastic force in a slightly stretched tension state without fully shrinking. Therefore, the mount plate 300 has a tendency to stay below the base plate 200, so that the cover (C) to maintain the closed state with respect to the main body (B) unless an external force is applied do.

Subsequently, when an external force is applied to the cover C to move upward, the mount plate 300 fixed to the cover C also slides upward with respect to the base plate 200. Then, the spring assembly 100 is rotated counterclockwise with the first locking projection 230 as a support point is gradually reduced in length. Then, the tension spring moves while the slider 120, which is indirectly coupled to the mounting plate 300 through the second coupling piece 123 and the slide bar 125, moves toward the tip end portion of the inner space 117 of the guide frame 110. 130 is gradually increased against the tendency to shrink.

Thereafter, as shown in FIG. 5B, the separation distance between the first locking protrusion 230 and the second locking protrusion 330 becomes a minimum to reach a transition point. At this time, the tension spring 130 is in the most elongated state, the elastic energy accumulation value reaches the maximum value.

Subsequently, when the external force is continuously applied to the cover C upwardly and passes the transition point, the direction of action of the spring assembly 100 having a tendency to stretch is changed instantaneously from the downward direction to the upward direction, and the mount plate 300 ) Will coincide with the direction of travel. As a result, as shown in FIG. 5C, the mounting plate 300 is rapidly moved upward, and is positioned on the upper side, and the cover C is in an open state. If the external force applied to the cover C disappears before reaching the transition point, the mount plate 300 moves downward by the spring assembly 100 which acts downward while tending to stretch. The cover C is in a closed state as it is.

As such, when the cover C is moved upward and opened, the spring assembly 100 is in a relaxed state again. However, the spring assembly 100 still tends to stretch because the tension spring 130 provides elastic force in a slightly stretched tension state without fully shrinking. Therefore, the mount plate 300 has a tendency to remain on the upper side with respect to the base plate 200, so that the cover (C) is opened with respect to the main body (B) unless an external force is applied. Will be maintained.

On the other hand, in the case of the operation of closing the cover C in the open state, the spring assembly 100 provides the elastic force of the spring in the direction in which the cover C is opened before the transition point, but once the transition point passes the cover C ) Provides semi-automatic opening and closing of the cover (C) by providing an elastic force of the spring in the closing direction.

Subsequently, a modified embodiment of the present invention will be described.

6 is a reference perspective view for explaining a spring assembly of a modified form of the present invention according to the first embodiment.

The modified embodiment according to FIG. 6 is characterized in that the compression spring 140 is further installed in the state in which the compression spring 140 is fitted to the guide rod 115 on the opposite side where the tension spring 130 is installed with the slider 120 interposed therebetween.

According to this configuration, the compression spring 140 assists the tension spring 130 to further increase the elastic force of the spring. This can provide a stronger elastic force required for semi-automatic opening and closing of the cover in a limited installation space.

7 is a reference perspective view for explaining a spring assembly of a modified form of the present invention according to the first embodiment.

In the modified embodiment according to FIG. 7, the coil type compression spring 150 is installed in place of the coil type tension spring 130 as described above. To this end, the compression spring 150 is installed in the inner space 117 of the guide frame 110, but is installed on the opposite side where the tension spring 130 before deformation is installed with the slider 120 interposed therebetween. This modified embodiment shows that not only the tension spring 130 but also the compression spring 150, and even other types of springs, can be installed if the direction of action coincides only.

8 is a reference perspective view for explaining a spring assembly of a modified form of the invention according to the first embodiment.

In the modified embodiment according to Figure 8 in place of the coil type tension spring 130 made of iron core material is characterized in that the linear tension spring 160 made of a rubber material is installed. Such a modified embodiment shows that the spring provided for the purpose of providing the elastic force for the semi-automatic opening and closing of the cover can be made of various materials.

[Second Embodiment]

And it is provided with a support frame (210C) formed in the shape of a rectangular frame corresponding to the guide frame 210 in order to bundle them together. The support frame 210C is a thin plate made of stainless steel, which is used as a molding frame when forming the guide frame 210, and then serves to bind two portions of the guide frame 210 to one after the molding is completed. Coupling portions of the guide frame 210 is provided with grooves 212A and protrusions 212B that are matched with each other for stable coupling.

In addition, the left side and the post of the inner space 217 of the guide frame 210 is provided with a guide rail 215 integrally formed with the guide frame 210 instead of the guide rod 115 before deformation.
