Description

Portable phone and sliding assembly for portable phone

The present invention relates to a mobile phone and a sliding assembly for a mobile phone, and more particularly, to improve the material and the sliding movement structure for the support and the slider to reduce the overall thickness and to prevent the occurrence of fine play between the support and the slider The present invention relates to a mobile phone and a sliding assembly for a mobile phone, which enable a smooth and smooth sliding operation of the cover part.

In recent years, mobile phones, which are frequently used anytime, anywhere, regardless of gender, age and age, are classified into flip type mobile phones, folding type mobile phones, and slider 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 slider type mobile phone that has recently appeared allows the cover to be slidably opened and closed with respect to the main body, and the latter has a higher preference than the latter flip type mobile phone or slider type mobile phone, rather than the former flip type. It is true.

Among the most recent slider-type mobile phones, a plurality of torsion springs are employed as a driving force for sliding the cover part with a display window with respect to the main body part provided with a plurality of input buttons. Patent Application No. 20-0319967 and No. 20-0308165.

Looking at the disclosed technology, both the main plate (hereinafter referred to as "support") supporting the main body of the cellular phone and the slide plate (hereinafter referred to as "slider") supporting the cover of the cellular phone are made of aluminum.

Guide slits are formed on both sides of the main plate (hereinafter referred to as "support part"), and guide ribs which are slid and guided to the guide slits are formed on both sides of the slide plate (hereinafter referred to as "slider").

A torsion spring is mounted between the support and the slider at both ends to secure both the support and the slider to impart a moving elastic force to the slider. Thus, when the slider is pushed up or down relative to the support, it is easy to move due to the elastic action of the torsion spring.

However, in this type of sliding assembly for a mobile phone, both the support part and the slider are made of aluminum, and since the rail structure such as the guide slit and the rib is formed on the side, it is not only limited in reducing the thickness but also in the assembly tolerance. As there is a minute play between the support and the slider as much as possible, there is a problem that the sliding drive of the cover portion is not smooth or smooth.

In addition, in the conventional sliding assembly, even if the thickness is reduced, due to the limitation of the material, the support cannot be reduced to less than 3 mm and the slider is about 2.24 mm. Therefore, there is a disadvantage that the mold bending operation is not applicable and must rely only on extrusion, which is expensive.

The object of the present invention is to improve the material and the sliding movement structure for the support and the slider to reduce the overall thickness and to prevent the occurrence of fine play between the support and the slider to make the sliding drive of the cover smooth and smooth A sliding assembly for a telephone and a mobile phone is provided.

In addition, to provide a mobile phone and a sliding assembly for a mobile phone to reduce the manufacturing cost by mold bending the support and the slider due to the material change.

On the other hand, the above object is also achieved by a mobile telephone, in which the sliding assembly of claim 1 or 2 is mounted so that the cover portion slides with respect to the main body portion.

Hereinafter, with reference to the accompanying drawings will be described in detail for each embodiment of the present invention, in the description of each embodiment, the same reference numerals will be given to the same configuration.

1A and 1B are views illustrating a process of sliding a cover part due to a sliding assembly for a mobile phone according to the present invention, and FIGS. 2A to 2C are plan views and side cross-sectional views, respectively, of the sliding assembly for a mobile phone according to the present invention. And forward sectional view.

1A and 1B, the mobile phone according to the present invention is composed of a main body 10 and a cover 20.

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 each 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 20 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) is provided. In addition to the display window 22, a pattern for identifying a phone number, a state of charge of the battery, whether vibration or an alarm state indicator is formed.

Although optional, a camera unit 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.

Meanwhile, FIG. 1A illustrates a state in which the cover 20 completely shields one surface of the main body 10 without using the mobile phone, and FIG. 1B illustrates the main body 10 for using the mobile phone. It can be seen that the cover 20 is slid to move the open area of the main body 10.

As such, in order to move the cover 20 from FIG. 1A to FIG. 1B, the present invention provided in the main body 10 and the cover 20 by pushing the cover 20 upward relative to the main body 10. The sliding assembly 30 may be operated.

The sliding assembly 30 for a mobile phone according to the present invention, as shown in Figures 2a to 2c, the support portion 32 for supporting the main body portion 10, the slider 34 for supporting the cover portion 20 ) And a plurality of torsion springs 36 mounted between the support part 32 and the slider 34.

The torsion spring 36 is provided to impart the moving elastic force of the slider 34 to the support 32, as also shown in the previously disclosed specification. To this end, both ends 36a and 36b of the torsion spring 36 are fixed to the projections 32a and 34a formed on the support part 32 and the slider 34, respectively.

A plurality of balls 38 are provided between the support part 32 and the slider 34 along the sliding movement direction of the slider 34. The plurality of balls 38 are used to more smoothly slide the slider 34 relative to the support 32, which corresponds to the conventional rail structure.

The support 32 and the slider 34 are provided with grooves 32b and 34b in which the balls 38 are partially accommodated so that the balls 38 can be mounted. As such, by employing the ball 38 while allowing the ball 38 to be inserted into the grooves (32b, 34b) to move, not only can reduce the overall thickness of the sliding assembly 30 compared to the conventional rail structure but also smoother Sliding movement can be implemented.

Of course, to be slid by the ball 38 as such, the slider 34 must slide without being separated from each other with respect to the support 32. Therefore, as shown in an enlarged view in FIG. 2C, after the end of the slider 34 is bent to form the rail ring portion 34c, the rail ring portion 34c partially covers the free end 32c of the support portion 32. It would be advantageous to be able to be wrapped with. Of course, contrary to the illustration, the free end of the support 32 may be bent to partially surround the end of the slider 34.

On the other hand, both the support part 32 and the slider 34 are made of stainless steel whose material is manufactured by die bending. Therefore, there is an advantage that the thickness can be kept much thinner than the conventional one made of aluminum.

That is, as shown in Table 1 below, in the conventional case, the support part could not be reduced to a thickness of about 3 mm and the slider was about 2.24 mm or less, but the support part 32 and the slider 34 of the present invention were 2.5, respectively. It can be reduced to about mm and 0.77 mm. Therefore, when looking at the overall thickness of the prior art and the present application, it can be seen that significantly reduced from 3 mm to 2.5 mm.

For reference, in Table 1 below, the overall thickness is the length of the largest width measured in the state in which the support part 32 and the slider 34 are coupled to each other. Thus, simply adding the support 32 and the slider 34 is not the total thickness.

TABLE 1

Prior art Headquarters Slider (mm) 2.24 0.77 Support (mm) 3 2.5 Full (mm) 3 2.5

Accordingly, unlike the conventional method, since the manufacturing method can be converted into a mold bending operation, the work efficiency is increased, rigidity is given, and the cost can be reduced.

In addition, since the thickness is reduced and the sliding movement structure is changed from the conventional rail type to the ball 38 type, it is possible to prevent the occurrence of minute play between the support portion 32 and the slider 34. Therefore, the sliding drive of the cover portion 20 can be made smoother and smoother.

Referring to the process of sliding the cover portion 20 due to the sliding assembly 30 for a mobile phone having such a configuration as follows.

As shown in FIG. 1A, the cover 20 is pushed up in the “B” direction as shown in FIG. 1B while the cover 20 covers a region of the main body 10. Then, as the torsion spring 36 elastically repels by the pressurized force, the slider 34 can be easily moved with respect to the support 32, so that the main body 10 can be opened as shown in FIG. 1B. When the main body 10 is opened in this manner, the input button 12 may be pressed to use a call, text, or voice message.

If the use of the cellular phone is completed, in order to return the cover unit 20 to the state of FIG. 1A from the state of FIG. 1B, the cover unit 20 is pushed down in the direction "A" of FIG. 1A. Then, the torsion spring 36 is resiliently repulsed in the above-mentioned opposite direction by the pressurized force, thereby easily moving the slider 34 with respect to the support part 32. As shown in FIG. It can be closed by the cover portion 20.

Thus, according to the present invention, by improving the material and sliding structure for the support portion 32 and the slider 34 (improved ball type) to reduce the overall thickness and fine play between the support portion 32 and the slider 34 This can be prevented from occurring and the sliding drive of the cover portion 20 can be made smoother and smoother. In addition, there is an effect that the manufacturing cost can be lowered by mold bending of the support part 32 and the slider 34 due to the material change.

On the other hand, according to the above-described embodiment, the torsion spring 36 is employed as a means for sliding the slider 34 relative to the support part 32. However, the idea of the present invention can be sufficiently applied to a mobile phone using a motor method in addition to the torsion spring 36 method.

3 is a view showing another embodiment of a sliding assembly for a mobile phone. As shown in this figure, the sliding assembly employed in the mobile phone as another embodiment of the present invention, the support 32 for supporting the main body 10, the slider 34 for supporting the cover 20 And a wire 38 provided in a portion of the support 32 and the slider 34 along the sliding movement direction of the slider 34 to slide the slider 34 relative to the support 32, and the wire 38. And a control button 16 provided on the side of the main body 10 to control the operation of the motor 39.

Accordingly, in order to move the cover 20 from FIG. 1A to FIG. 1B, the control button 16 formed on the side of the main body 10 is pressed. Then, the motor 39 is driven and the slider 34 is moved relative to the support part 32 while the wires 38 supported by the plurality of support tools 37 move in one direction by the operation of the motor 39. Therefore, the cover part 20 can move from FIG. 1A to FIG. 1B.

On the contrary, in order to move the cover unit 20 from FIG. 1B to FIG. 1A, the cover unit 20 may press the control button 16 to perform the reverse operation described above. Therefore, it is advantageous if the control button 16 is employed as a tact switch or the like that can operate both by one signal, and it is advantageous to apply that the motor 39 can also rotate in both forward and reverse directions. Therefore, the motor 39 is irrelevant whether it is a DC motor or an AC motor.

Of course, as shown in FIG. 3, even if the automatic sliding structure by the motor 39 is adopted, it is good to change both the support part 32 and the slider 34 to stainless steel as mentioned above. Then, the overall thickness is reduced and compact, while the manufacturing method can be converted into a mold bending operation, the work efficiency is increased, rigidity is given, and the cost can be reduced.

Further, in addition to the material change, as described above, it is preferable to change the sliding movement structure from the conventional rail type to the ball 38 type to prevent the occurrence of minute play between the support portion 32 and the slider 34. Then, the sliding drive that the cover 20 is moved from FIG. 1A to FIG. 1B, or FIG. 1B to FIG. 1A by the operation of the control button 16 has the advantage of being smoother and smoother.

Although the present invention has been described in detail with reference to the drawings, the present invention is not limited thereto.

In the above-described embodiment, the sliding assembly has been intensively described, but it should be noted that a mobile phone equipped with a sliding assembly having such a configuration and an effect so that the cover part slides with respect to the main body is also within the scope of the present invention. There is no.

In the above-described embodiment, it can be seen that the camera unit is provided and various function buttons are provided in the cover unit. However, there is no problem in applying the present invention even if the camera unit is missing or the positions of the function buttons are changed.

In the above-described embodiment, the control button is provided on the side of the main body portion, but the installation position of the control button may be provided in any position because it is irrelevant to the idea of the present invention.

As described above, according to the present invention, by improving the material and the sliding movement structure for the support and the slider to reduce the overall thickness and to prevent the occurrence of fine play between the support and the slider to make the sliding drive of the cover more smooth and smooth It can be effective.

In addition, according to the present invention, there is an effect that the manufacturing cost can be lowered by mold bending the support and the slider due to the material change.
