The present invention relates to a sliding assembly for a mobile phone, and more particularly, to improve the sliding structure by providing a spring mounted to provide elastic repulsion inside the sliding assembly of the sliding type mobile phone to smooth the sliding movement and the thickness occupied by the spring. The present invention relates to a sliding assembly for a mobile phone having a spring which has a reduced durability and a thinner thickness of the mobile phone and has improved durability.

In recent years, mobile phones, which are frequently used anytime, anywhere, regardless of gender, age, or family, are classified into flip type mobile phones, folding type mobile phones, and sliding type mobile phones. The flip type mobile phone can flip open / close only a part of the main body with the input button while the display window is exposed to the outside. The folding type mobile phone can rotate the cover part about the main body part about the hinge of the center. I would have to.

In recent years, the sliding type mobile phone has been developed so that the cover part can be opened and closed with respect to the main body, and in the recent years, the preference of the latter folding type mobile phone or sliding type mobile phone is increasing rather than the former flip type.

Among the most recent slider-type mobile phones, a plurality of torsion coil springs are employed as the driving force for sliding the cover part with the display window relative to the main body part provided with the plurality of input buttons. It is disclosed in the Republic of Korea Patent Office registered Utility Model Publication No. 20-0319967 and No. 20-0308165.

Looking at the disclosed technology, the sliding assembly of the mobile phone is composed of a main plate for supporting the body portion of the mobile phone and a slide plate for supporting the cover of the mobile phone, each of which is made of aluminum, the guide plate is formed on both sides of the slide plate Guide ribs slidingly guided to guide slits are formed on both sides of the main plate.

And, between the main plate and the slide plate, both ends are fixed to the main plate and the slide plate, respectively, is provided with a non-slip coil spring for imparting a moving elastic force for sliding movement. Accordingly, when the cover part is pushed up or down to one side of the main body part, the cover part is slid and moved to open and close the main body part by the elastic repulsive force of the torsion coil spring.

However, since the torsion coil spring used in the related art is a spring having a shape in which the central coil part is layered to be layered a plurality of times, the total thickness of the spring may be several times the thickness of the steel wire which is the material of the spring. However, when the spring becomes thicker, the distance between the two opposite surfaces of the main plate and the slide plate must be that far, so the mobile phone becomes thicker.

However, each cell phone maker is competing to reduce the thickness of the cell phone, and the thickness of the cell phone is displayed in the advertisement up to 0.1mm units, so it is highly desirable if the thickness of the spring can be reduced.

However, in order to reduce the thickness of the spring, thinning the thickness of the steel wire, which is a material of the spring, has a limitation in that the elasticity and durability of the spring are reduced, and when using a conventional torsion coil spring, there is a layer of overlapping parts, which increases the thickness of the spring. There is a problem that there is a fundamental limit to the reduction.

In addition, in case of torsion coil spring, it is necessary to limit the thickness, so there is a limit in elastic repulsion force because it does not wind up a large number of times. There is also a problem. If the spring inside the sliding assembly loses its function, the user must apply the force from the beginning to the end to open and close the cover of the mobile phone. Therefore, the inconvenience is large, and in some cases the coupling between the cover and the body is loose. It can also open and close when it's not, causing the entire phone to be replaced.

The present invention has been made to solve the above problems, the present invention is to reduce the thickness compared to the conventional by mounting the spring of the sliding assembly is an improved type of spring placed on one plane instead of the conventional torsion coil spring It is an object of the present invention to provide a sliding assembly for a mobile phone which can be operable and excellent in durability.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1A and 1B, a mobile phone equipped with a sliding assembly according to the present invention is composed of a main body portion and a cover portion.

The main body 10 is a part constituting the body of the cellular phone, and one side thereof is provided with a plurality of input buttons 12 as input means for inputting a telephone number or a text message. In the lower portion of the input button 12, a transmitter 14 is provided as a means for transmitting a user's voice to the other party or recording a voice message.

On one surface of the cover portion for selectively opening and closing the area of the input button 12 of the main body 10, a display window 22 for displaying a signal input by the input button 12 and various function buttons 24 are provided. . In addition to the display window 22, a pattern for checking a phone number, a state of charge of the battery, whether vibration is present, an alarm state display, etc. is formed. Although optional, a camera section 26 is provided on the upper portion of the display window 22 for capturing an image such as a picture or a picture. In the vicinity of the camera unit 26, a receiver 28 for listening to a voice from the other party is provided.

2 is an exploded perspective view of the sliding assembly for a mobile phone according to an embodiment of the present invention, the sliding assembly is a main plate 41 fixedly installed on the surface facing the cover portion 20 of the main body portion 10, A slide plate 31 fixedly installed on a surface of the cover part 20 so as to contact the main plate 41, and at least one spring 51 mounted between the main plate 41 and the slide plate 31; , One or more spring fixing protrusions 43 for fixing one end of the spring 51 to the main plate 41.

The slide plate 31 and the main plate 41 are provided with predetermined guide means. The guide means are formed on both side surfaces of the slide plate 31 in the longitudinal direction, and formed on both side portions of the main plate 41, respectively, to couple with the guide slits 32, respectively. Consisting of guide ribs 42. The guide rib 42 of the main plate 41 is tightly inserted into the guide slit 32 of the slide plate 31 so that the cover 20 is engaged with the main body 10 so that It becomes possible to flow in the longitudinal direction of a mobile telephone.

On the other hand, at least one spring 51 is installed between the slide plate 31 and the main plate 41, the spring 51 is a spring like the torsion coil spring as shown in FIG. It is not formed to overlap in the thickness direction of the mobile phone, and is formed in a shape wound on one plane such as a spiral spring used in conventional watches and the like.

4 illustrates a state in which the cover part 20 completely overlaps the main body part 10. The spring 51 is provided with two springs of the same shape, each of the first end 53 of the two springs 51 is bent end so that the curly part is provided on both sides of the slide plate 31 The second ends 52 of the two springs 51 are fixed by being inserted into each of the fixing holes 33, and each of the two spring fixing protrusions 43 joined to the main plate 41 is rolled roundly. I get caught.

In fixing the two springs 51, the fixing of the spring ends is such that the first end 53 of one of the two springs 51 is fixed at a point near the left edge of the slide plate 31 and the second end. 52 is fixed at a point in the right half region of the main plate 41, and the first end 53 of the other one of the springs 51 is fixed at a point near the right edge of the slide plate 31 and The two ends 52 are preferably configured to be fixed at points within the left half region of the main plate 41.

When the second end 52 of the spring 51 coupled with the main plate 41 is opposite to the above manner, the maximum movement distance of the main plate 41 is significantly reduced in comparison with the above manner. This is because the space in the width direction of the slide plate 31 cannot be utilized to the maximum. There is a correlation between the maximum travel distance L of the main plate 41 and the width W of the slide plate 31. If the width W is narrowed, a constraint is placed on increasing the maximum travel distance L. In obtaining the same maximum travel distance L, following the above scheme can make the width W of the slide plate 31 small. This is because when following the above method, the two springs 51 make full use of the width (W) direction spacing when compressing-extensioning while rotating. The mobile phone is required to be designed in a short and thin structure, but the above method is advantageous in order to obtain the required maximum travel distance L while reducing the width W of the main plate 41 and the slide plate 31.

The portion of the spring 51 close to the second end 52 forms a spirally wound shape while the radius is gradually increased to form a swirl shape around the second end 52.

The number of times wound in this embodiment is suitable for 2 to 4 times and may be less than 2 times.

From the end point of the swirl in the spring 51 to the first end 53 has a form almost close to the straight line forming a fine curve.

The material of the spring 51 is usually stainless steel. Piano wires or other materials having equivalent to superior reliability and elasticity may be used, and the diameter of the band steel used as the material of the spring 51 is 0.4 to 0.6 mm. The spring will first be

After forming by bending or rolling as much as possible, the whole spring can be rolled to be flat, so that a thickness of 0.2 to 0.3 mm can be produced to produce a thinner spring.

The reason for holding the shape of the spring before rolling is that if the spring is formed to be flat and then the spring is formed, there is a problem that the material is not bent well and the flat state is not maintained. This is because the flatness is maintained again during rolling even if a partially twisted portion occurs during spring forming. Alternatively, only the portion curled round the circumference of the spring fixing protrusion 43 among the springs, not the entire spring, may be rolled so that only this portion is flat. This is because the end of the spring fixing projections 43, which prevents the wound portion of the springs from falling out, protrudes more than the thickness of the spring, so that the end of the spring fixing projections 43 may scratch the slide plate 31 when sliding. Therefore, by flattening the portion of the spring wound on the spring fixing protrusion 43, the protruding length of the spring fixing protrusion 43 is similar to the overall thickness of the spring to prevent the risk as described above.

When the main plate 41 is slightly moved upward in this state, the elastic repulsive force of the spring 51 is applied downward of the main plate 41, which has the property of always returning to its original form. Therefore, when the first end 53 and the second end 52 of the spring 51 are closer than the first state, the first end 53 and the second end 52 of the spring 51 are farthest. Force is applied from the spring 51 so that it is. Therefore, before the second end 52 is moved to be above the first end 53, the spring 51 is always forced to move the main plate 41 downward so that the cover portion 20 slides by a certain distance. Until the user is forced to push the cover unit 20 by hand, the cover unit 20 can be opened to the end.

FIG. 5 illustrates a state in which the cover part 20 opens a part of the main body part 10 as an intermediate state in the process of sliding the cover part 20 with respect to the main body part 10.

When the slide plate 31 is moved, the second end 52 of the spring rotates around the spring fixing protrusion 43, the first end 53 of the spring rotates in the fixing hole 33, and the spring 51. The bending force is generated by the elasticity of the spring 51 to return to its original state as shown in the figure, based on the point where the height of the first end 53 and the height of the second end 52 are equal to each other. If the second end 52 is below the first end 53, the main plate 41 is pushed downward by the spring 51, and if the second end 52 is above the first end 53, the main plate 41 is above the first end 53. 41 is forced upward by the spring 51. Therefore, if the user only applies a force until the cover portion 20 exceeds the reference point, the cover portion 20 is automatically moved and opened without applying a force thereafter.

FIG. 6 illustrates a state in which the cover part 20 opens a part of the main body part 10 by sliding the end of the main body part 10 with respect to the main body part 10.

To close the cover 20 in this state, the user applies a force to push the finger downwards on the cover 20.

7-12 illustrate various embodiments of a sliding assembly for a mobile phone according to the present invention.

All of these embodiments are identical in that one end of one spring 51, 61 is fixed to the slide plate 31 and the other end is fixed to the main plate 41.

The spring 61 in FIG. 7 has a different appearance from the above-described spring, and both spring portions near the first end and near the second end are vortexed. Such springs will be referred to as plural roll springs 61 below, and the singular roll springs 51 having a swirl shape on only one side will be defined.

7 shows that two plural roll springs 61 are installed, and the plural roll springs 61 are wound in the plural roll springs 61 by a predetermined length from the first end of the spring 61 and swirled. The first end and the second end of the spring are bounded by a line extending in a straight line, which is also wound in a counterclockwise direction from the second end of the spring. And are positioned opposite each other.

Compared to the singular roll spring 51, the plural roll spring 61 has an advantage that the stress of the spring 61 is distributed to both sides, thereby improving durability.

8 is also provided with two plural roll springs 61, the plural roll springs 61 are wound in a counterclockwise direction by a predetermined length from the first end of the spring 61 to form a swirl shape. In this case, the first and second ends of the spring are both on the same side, based on the member connecting the two vortex parts by winding them clockwise by a predetermined length from the second end of the spring. It differs from the embodiment shown in FIG. 7 in that it is located. In the case of the embodiment shown in Figure 8 there is an advantage that the stress distribution in the spring is more efficient because the stress is dispersed even in the member connecting the vortex portion of both sides.

9 and 10 show an embodiment in which only one plural roll spring 61 is mounted, and thus there is no significant problem in operability even if configured in this way.

11 and 12 both show an embodiment in which one plural roll spring 61 and one singular roll spring 51 are mounted, and the first and second ends of the singular roll spring 51 are fixed. The only difference is that the positions are opposite each other.

FIG. 13 illustrates an embodiment in which only one singular roll spring 51 is mounted. In this case, the elastic force of the spring 51 may be weak and the life thereof may be short as compared with other embodiments.

14A and 14B show a stacked spring 71 in which two plural roll springs 61 are fixed to the same spring fixing projection 43 at each end and overlapped in two planes. In the case of applying the stacked spring 71, when the two springs are installed, the spring occupies a smaller area than that of the embodiment shown in FIG. 7 or 8.

15A and 15B show the stress distribution enlarged stacked spring 71.

Because the stress is applied to the part that connects between the two vortex parts, the longer the length, the better the stress distribution and the better the spring stability. To achieve this effect, the length of this part can be increased by making this part arc, as shown in Figs. 15A and 15B. As a result, the role of the vortex portion is reduced relatively, so that the vortex portion may have a sufficient effect of stress dispersion even if the length thereof is short, so that the vortex portion may be semi-circular as shown in FIG. 15B. As shown in FIGS. 17A to 17D, there may be no vortex-shaped portion, and rigidity can be secured as necessary through several layers of stacked structures.

16A, 16B, and 17D show a convex portion 72 formed in the center of the stress distribution type laminated spring. This structure has the advantage that the portion connecting between both parts of the vortex becomes longer, which adds to the effect of stress dispersion.

In the detailed description of the present invention, the mobile phone is limited to the above description, but the sliding assembly may be equally applicable to various sliding portable devices such as PDAs and calculators in addition to the mobile phones.

As described above, in the sliding assembly for a mobile phone according to the present invention, since all the parts of the spring are located on one plane, the thickness of the mobile phone is reduced by at least 1/2 compared to the conventional torsion coil spring, and the thickness of the mobile phone is made thin. It is advantageous in that, while the thickness is reduced, the number of windings of the spring can be increased, thereby improving the elastic repulsive force of the spring, thereby improving workability, and the length of the steel wire forming the spring is long enough to deform the torsion coil spring. Since it is much less than the fatigue fatigue due to the repeated deformation of the spring member has a long durability and long life, there is an advantage that can be manufactured in various shapes and numbers depending on the type of mobile phone.

As described above, the present invention has been described only with respect to specific examples, but it will be apparent to those skilled in the art that various changes and modifications can be made within the technical spirit of the present invention based on the above specific examples. And modifications belong to the appended claims.
