Description

Elastic module having a narrow trajectory and a slide device of a sliding type mobile phone having the same {Elastic module and slide apparatus of sliding type cellular phone having the elastic module}

The present invention relates to a slide device of a sliding type mobile phone, and more particularly, in order to slidably couple the sliding block from the fixed block by using a torsion spring in a vertical direction so as to overlap a part of the two bodies so that there is no vertical shaking between each other. In addition, the present invention relates to an elastic module capable of narrowing a turning trajectory and a sliding device of a sliding type mobile phone having the same.

Mobile phones are preferred for their small size because their primary purpose is to carry them, and they prefer to have a special design or include a variety of functions. Therefore, referring to the mobile phones that are released these days, small and thin products are continuously released, and lighter and better design products are popularly sold in the market.

Mobile phones are generally classified into flip type, folder type and sliding type according to their appearance and operation method. The current mainstream is sliding type mobile phones.

The sliding cell phone refers to a cell phone in which a main part and a sliding part are overlapped with each other, and a display part and a key input part face the same direction in each part. In general, the sliding type mobile phone may slide the front sliding part relatively to expose the display unit or the key input unit that is hidden on the rear side. For example, there is a mobile phone that can push up the front sliding part to expose the key input unit formed on the front of the main part of the rear. In addition, there is also a mobile phone that can expose the display formed on the front of the main part of the rear by moving the sliding part of the front in which the key input unit is formed downward.

On the other hand, the sliding mobile phone is a FPCB (Flexible Printed) for connecting a slide device for fastening the sliding part on the upper part of the main part by a slide method, and a key input unit, an LCD screen, and a battery, which are respectively located on the main part and / or the sliding part. Circuit board). At this time, the FPCBs are arranged to be connected to each other through a through hole formed on one side of the fixing block constituting the slide device. And the slide device is configured to impart an elastic force during the slide movement using the elastic module.

Korean Laid-Open Patent Publication No. 2008-0005087 discloses an elastic mechanism constructed by using a torsion spring wound in one direction or an integrated torsion spring wound in both directions so as to be used in a portable device such as a wireless telephone, a PDA, or a PMP. Disclosed are techniques such as sliding switchgear. The torsion spring used in this technology is a spiral spring wound in a spiral like a spring without overlapping parts. It is commonly used and widely used in linear motion or rotational motion such as a toy car, a brake, and a seat belt.

As described above, this technique has a merit that it can be miniaturized by using a spiral spring that can provide sufficient elastic force, so that it does not need to consider interference with the FPCB. However, as shown in FIG. 1A, when the integrated spiral spring 110 wound in both directions in a winding shape is used, the spiral spring 110 is seated on the connecting member 120, and a pair of spiral springs 110 are wound. By coupling the arm member 130 to the connection member 120, the elastic mechanism 100 was implemented. Here, the connecting member 120 is to be mounted to the spiral spring 110, so that it must be molded to have a certain shape. However, a case having a shape is difficult to manufacture by a press molding method, and should be manufactured by injection molding, metal injection molding, or die casting molding. In this case, the molding thickness becomes thick and the strength is weak. That is, the molding methods are difficult to follow the advantages of the press molding method with respect to the control of the strength or molding thickness of the product.

However, the elastic mechanism 100a illustrated in FIG. 1B includes two spiral springs 110a wound in one direction in a winding shape, and a connecting member 120a and a cover for seating and fixing the two spiral springs 110a. 130a). Since the elastic mechanism 100a uses the connecting member 120a manufactured by the press molding method, the elastic mechanism 100a can be thinned. However, the elastic mechanism 100a is exposed at both sides of the cover 130a, respectively, and one end of the spiral spring 110a is exposed, and the ends thereof are fixed to the blocks of the sliding switch, respectively. As one side of the spiral spring 110a which is a single line is twisted, shaking occurs up and down. Therefore, since the rotational motion space as much as the value according to this shake should be higher, not only the thickness is limited, but also has a bad effect of thickening the cell phone thickness.

In addition, Korean Patent Registration No. 0796944 discloses an elastic module developed by the inventor. The elastic module 200 is a unitary spring 210 composed of first and second coil parts 211 and 212 wound in different directions from one end to a predetermined length in a winding shape and a connecting part 213 connecting them to each other. And both ends of the integrated spring 210 are fixed, and the first and second coil parts 211 and 212 are housed in the state in which the connection part 213 is exposed to the outside, and the hinge shaft is disposed at one side. It is comprised by the pair of case 220 which has the groove | channel 221, respectively.

However, this technique is because when the pair of cases 220 are connected to each other only by the connecting portion 213 of the integrated spring 210 and do not have a separate engagement relationship between the pair of cases 220, when the slide movement between blocks Unable to control up and down shaking, there was a difficulty of elaborate sliding. In addition, the friction between the case and the block due to the vertical shaking of the pair of case 220 during the slide movement between the blocks, there was a problem that the noise or dust generated.

In addition, the elastic mechanism (100, 100a) and the elastic module 200 of Figs. 1a to 2 is an integral spiral spring 110 wound in both directions in a winding shape, two spiral springs (110a) wound in one direction in a winding shape. Alternatively, since the integrated spring 210 wound in both directions in a winding shape is used, the width of the springs increases, so that the turning trajectory is widened. In addition, one end of the spring (110, 110a, 210) of the elastic mechanism (100, 100a) and the elastic module 200 of Figure 1a to 2 is fixed to one side of the connection member (120, 120a) or case 220 It has a structure. Therefore, when the springs 110, 110a, and 210 are wound and unwound, stress is concentrated on the fixed ends, and thus a fatigue phenomenon occurs, thereby causing the fixed end portions to be damaged.

Therefore, the present invention has been made to solve the problems of the prior art as described above, in the sliding block coupled to the sliding block in the vertical direction from the fixed block by using a torsion spring overlapping a part of the two bodies to each other It is an object of the present invention to provide an elastic module capable of narrowing the turning trajectory as well as the vertical shaking and a slide device of the sliding type mobile phone having the same.

The spring 310 of this structure determines the torsion force according to its cross-sectional area. Thus, the spring 310 of this embodiment has a rectangular cross-sectional shape of long width and low height as shown in the figure. That is, the spring 310 of this embodiment may be configured in various forms such as a circular cross section or a shape in which upper and lower ends of the circular cross section are cut. However, in this embodiment, the elastic module 300 is made thin by using the spring 310 having a rectangular cross-sectional shape having a lower height than the width among the rectangular shapes having the same area.

The first and second bodies 320 and 330 are made of stainless steel plates, and the width of the first and second bodies 320 and 330 gradually decreases from one side to the other side. At this time, one side of the first and second body 320, 330 has a width that can cover the coil portion 312 of the spring 310 on the upper or lower surface. In this embodiment, the body located on the lower surface of the coil unit 312 is referred to as the first body 320, and the body located on the upper surface of the coil unit 312 is referred to as the second body 330. .

The first body 320 has a first hole 321 formed at one side and a coil portion 312 of the spring 310 to be coupled to the second body 330 by a rivet 340, which is a kind of fixing member. Fixing the guide portion 322 and the first body 320 to the fixing block or the slide block of the slide device while supporting the first extension portion 311 of the spring 310 to move so as to be wound and unwound It has a second hole 323 formed on the other side. Here, the first hole 321 has a depth greater than or equal to the thickness of the first body 320 as the portion of the first body 320 is drawn out to protrude to one surface, but the second hole 323 has the first body. As the hole 320 is drilled, it has a depth corresponding to the thickness of the first body 320. In addition, the guide part 322 is formed by cutting a portion of the first body 320 and then bending it in a "b" shape, and the first extension part 311 in the free end state is the first body 320.

The stopper 324 has an upwardly inclined surface 324a protruding from one side of the first body 320 to have an upwardly inclined angle toward the other side, and has a cutting surface 324b that is cut vertically at an end thereof.

The second body 330 is a rivet 340 or the like as the first hole 331 formed on one side for coupling with the first body 320 and the coil portion 312 of the spring 310 according to the winding and unwinding A guide part 332 for guiding and supporting the second extension part 313 of the spring 310 to move, and a second hole for fixing the second body 330 to a fixing block or a slide block of the slide device ( 333). Here, the guide portion 332 is configured in the same way as the guide portion 322 of the first body 320 serves the same function.

In addition, the second body 330 has a stopper 334 protruding downward from the outside near one side thereof. The stopper 334 has a downwardly inclined surface 334a which protrudes from one side of the second body 330 to have a downwardly inclined angle toward the other side and has a cutting surface 334b that is cut vertically at the end.

The stoppers 324 and 334 of the first and second bodies 320 and 330 have an initial state between the first and second bodies 320 and 330 due to their cutting surfaces 324b and 334b contacting each other as shown in FIGS. 9 and 11. In addition to determining the angle, it acts as a sanction for turning to the initial state only when the applied torsion force is removed and returned. In addition, the inclined surfaces 324a and 334a of the stoppers 324 and 334 merely combine the respective components as shown in FIGS. 5 and 6, so that the respective stoppers 324 and 334 are free from contact with each other. As shown in FIGS. 9 to 11, when the first and second bodies 320 and 330 are pivoted with each other to achieve the completed state, the elastic module 300 serves to enable smooth sliding while sliding contact with each other. .

The rivet 340 has a hinge shaft 341 having a size that is rotatable in a state of being inserted into the first hole 321 of the first body 320, and a fixing part 342 fixed to the second body 330. Has That is, the rivet 340 serves to connect and fix the first body 320 and the second body 330 so that the first body 320 can pivot along the circumferential surface of the hinge axis 341.

First, the components arranged as shown in FIGS. 3 and 4 are connected to each other by fixing the first body 320 and the second body 330 using rivets 340 as shown in FIGS. 5 to 8. Then, as shown in FIGS. 7 and 8, the first and second bodies 320 and 330 are arranged at a predetermined angle to each other. At this time, the first and second extension parts 311 and 313 of the spring 310 are outside of the first and second bodies 320 and 330 by the guide parts 322 and 332 in a free end state which is not constrained anywhere. In addition to being supported so as not to deviate to the side, slide movement is possible. In addition, the stoppers 324 and 334 of the first and second bodies 320 and 330 are spaced apart from each other and are in a free state, respectively. Therefore, when the thin elastic module 300 in this state is used, since the first and second bodies 320 and 330 can be turned in both directions with respect to each other, the sliding device of the sliding type mobile phone in this state is provided. If adopted, there is a risk of malfunction. In addition, when turning in one direction, since the first and second extension parts 320 and 330 of the spring 310 are not supported by the guide parts 322 and 332, they cannot perform their functions.

In this embodiment, therefore, the first and second bodies 320 and 330 are pivoted with each other in the above state. Then, the inclined surfaces 324a and 334a of the stoppers 324 and 334 move in sliding contact with each other, and then contact each other at the cutting surfaces 324b and 334b, thereby opening the first and second bodies 320 and 330 downward. Production is completed in an obtuse state. In the elastic module 300 manufactured as described above, the first and second bodies 320 and 330 have a certain initial torsion force. In addition, in the elastic module 300 of this embodiment, the stoppers 324 and 334 of the first and second bodies 320 and 330 contact each other in an initial state before operation, but the first and second bodies 320 and 330 When turning the to each other, the stoppers (324, 334) are spaced apart from each other and in contact with each other in the original position.
