130: Slide hinge 150: Torsion spring

The present invention relates to a slide type personal portable terminal. More specifically, the present invention relates to a slide hinge device interposed between two sliding parts in a slide type terminal and a torsion spring for providing a semi-automatic opening and closing function to the slide hinge device.

Mobile phones may be generally classified into a flip type, a folder type, and a sliding type according to their appearance or operation. Among them, the sliding type mobile phone is arranged to overlap two sliding bodies, and the display unit and the key input unit are disposed in the same direction on each of the sliding bodies. In general, the sliding type mobile phone may expose the display unit or the key input unit that is covered by the rear side by relatively moving the sliding body of the front. In general, there is a structure that pushes the front sliding body upward to expose the key input formed on the rear sliding body, on the contrary, by moving the front sliding body formed with the key input downward to expose the display formed on the rear sliding body. There is also a structure.

The slide-type mobile phone includes a sliding body overlapping up and down, and a sliding hinge device for connecting both bodies is interposed between the sliding bodies to interconnect the sliding bodies, and may assist sliding of each other. .

1 is an exploded perspective view illustrating a conventional slide type mobile phone, and FIG. 2 is a rear view illustrating a slide hinge device applied to a conventional slide type mobile phone.

Referring to FIGS. 1 and 2, the conventional mobile phone 10 employing the slide method includes a main part 20 having a keypad formed on the front lower side and a slide part 30 mounted with a liquid crystal display. The slide part 30 slides up and down with respect to the main part 20, opens and closes the keypad through the movement of the slide part 30, and activates the function of the mobile phone 10.

In general, the slide hinge device 40 is interposed between the main part 20 and the slide part 30. The slide hinge device 40 includes a rail plate 42, a slide hinge 44 and a torsion spring 50. The rail plate 42 is mounted to the rear surface of the slide part 30, and the slide hinge 44 is mounted to the front upper end of the main part 20. In addition, the slide hinge 44 may be coupled to both sides of the rail plate 42 to guide the vertical movement of the rail plate 42.

Both sides of the rail plate 42 are provided with rails formed in the vertical direction, and grooves or holes corresponding to the rails are formed on the inner side of the slide hinge 44. Since the rail and the groove are slid in a slidable state, the slide part 30 can slide along the path defined for the main part 20.

A torsion spring 50 is interposed between the rail plate 42 and the slide hinge 44.

3 is a front view illustrating a torsion spring mounted to the slide hinge device of FIG. 2, and FIG. 4 is an enlarged perspective view of a portion A of FIG. 3.

3 and 4, the torsion spring 50 is formed by molding a metal wire, and the metal wire is formed into a cylindrical shape having a small diameter. The metal wire structure includes a wire connection portion extending from both ends of the central coil portion and the coil portion to the rail plate 42 and the slide hinge 44, respectively, because one of the wire connections extends from the center of the coil portion. In the part indicated by A, the two wires overlap each other up and down and have a thickness twice as relatively.

Since the torsion spring used in the conventional slide mobile phone has a diameter of about 0.5 mm, the overlapping portion of the wire has a thickness of about 1.0 mm, which is twice the diameter, and at least about 1.0 mm between the rail plate and the slide hinge. It should be possible to provide spaces with heights above.

In recent years, in view of the development of a slide hinge device having a thickness of about 2 ~ 3mm, the clearance space of about 1.0mm or more can be a major obstacle in reducing the thickness of the slide hinge device.

In addition, a method of reducing the clearance space by reducing the diameter of the torsion spring may be proposed, but as the diameter of the spring decreases, the elastic force decreases, so that the slide movement between the parts may not be smooth, and the function of opening and closing the parts semi-automatically may be reduced. Can be. It may also adversely affect reliability and shorten operating life.

Therefore, one object of the present invention for solving the above problems of the present invention is to provide a thin thickness of the torsion spring, and to provide a slide hinge device and a torsion spring that can be driven semi-automatically sliding.

Another object of the present invention is to provide a slide hinge device and a torsion spring which can reduce the height of the spring and provide sufficient elastic force for semi-automatic opening and closing, as in the conventional spring.

It is still another object of the present invention to provide a slide hinge device that binds a guide frame to a slide guide with a thinner structure, reduces the number of processes for manufacturing, and reduces a defective rate.

According to a preferred embodiment of the present invention for achieving the above objects of the present invention, the slide hinge device of the present invention includes a rail hinge portion, a slide hinge portion and a torsion spring. The rail hinge portion is mounted on the back of the slide part, and the slide hinge portion is mounted on the front of the main part. In the present specification, the slide part and the main part distinguish two parts moving in a relative concept, and the function and shape of each part may be variously changed and selected according to the intention of the terminal manufacturer. However, in general, a keypad and a battery are mounted on the main part, and a display, etc. are mounted on the slide part. The slide hinge device of the present invention is interposed between the slide part and the main part to serve to guide the slide movement between both parts.

The rail hinge portion includes a slide rail disposed along the moving direction of the slide part, and the slide hinge portion includes a slide guide slidably coupled to the slide rail. The slide rail may be a long protrusion or groove integrally formed with the rail hinge portion, and the corresponding slide guide may be a groove or protrusion corresponding thereto. Alternatively, the slide rail may be a guide bar assembled on the side of the rail hinge portion, and the slide guide may include a through hole for receiving the guide bar. The slide hinge part may be mounted on the main part, and may have various structures to limit the movement of the rail hinge part in one direction to allow the slide part to perform a linear reciprocating motion or a curved reciprocating motion.

The torsion spring is characterized in that it comprises a flat elastic coil portion and a wire connection portion. First, the elastic coil unit may be wound at least once or more, and may be wound in a spiral in which the distance from the center is gradually increased to form a single layer. However, one wire connection portion is structurally overlapped, the cross section of the entire or part of the elastic coil portion and the wire connection portion can be formed relatively flat to form a height smaller than the width. In general, the top and bottom of the wire constituting the torsion spring can be formed flat to make the cross section flat, and only one of the top or bottom of the wire can be flat. Moreover, the cross section of the wire which comprises a torsion spring can also be formed in square or hexagon shape.

If the torsion spring is made too small, the torsion spring cannot provide sufficient restoring force. Therefore, the cross section of the wire constituting the torsion spring has a width of about 0.4 to 0.6 mm, and about 0.1 to 0.4 mm. Its dimensions can be optimized to have a height of.

According to another preferred embodiment of the present invention, the slide hinge device of the present invention can use a torsion spring having a single layer wire structure. Single layer torsion spring does not have a wire structure overlapping up and down, the whole spring is composed of a single layer (single layer). The torsion spring of the present invention may also have a variety of structures to implement a single layer of spring but to provide sufficient elastic force. For example, an arc-shaped arc elastic portion may be formed instead of a portion of an elastic nose for connecting the wire hinge portion extending to the rail hinge portion and the slide hinge portion, or a wave-shaped wave elastic portion may be formed. It is also possible to form a folded elastic portion having a bent shape. As another example, a coil elastic part forming a single layer may be formed at one end to form a rotation axis at the center thereof, and a wire connection part extending in a curved shape may be removed to remove a portion overlapping vertically.

By the above method, the single-layer wire spring with elasticity is manufactured so that there is no overlapping part in two layers, so that the thickness of the slide hinge device can be made thinner, and when applied to the personal portable terminal, the thickness of the personal portable terminal is also reduced. It can be manufactured thinly.

In the present specification, a personal portable device is a portable electric and electronic device such as a personal digital assistant (PDA), a smart phone, a handheld PC, a mobile phone, an MP3 player, and the like. A predetermined communication module such as a Division Multiplexing Access module, a Bluetooth module, an infrared communication module (IrDA), a wired / wireless LAN card, etc., and a terminal having a predetermined computing power by mounting a predetermined microprocessor for performing a multimedia playback function Can be used as a generic concept.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, but the present invention is not limited or limited by the embodiments.

In the slide-type personal portable terminal, the rail hinge 110 and the slide hinge 130 may be fixed to the slide part and the main part, respectively, and these parts may be interposed between the rail hinge 110 and the slide hinge. By the mutual movement between the branches 130 can be opened and closed in a sliding manner. As illustrated in FIG. 1, the rail hinge 110 may be mounted on a slide part on which a display unit is mounted, and the slide hinge 130 may be mounted on a main part on which a key input plate and a battery are mounted.

The rail hinge portion 110 is a rail plate 112 fastened to the slide part of the personal mobile terminal, upper and lower ends 122 and 124, and the rail plate (124) located on the upper and lower portions of the rail plate 112 Two guide bars 126 disposed parallel to the sides of 112. The rail plate 112 is coupled to the upper finisher 122 and the lower finisher 124, and both ends 122 and 124 may be integrally connected. The rail plate 112 may be manufactured in a thin thickness by processing a metal sheet by pressing. At this time, the side of the rail plate 112 may be bent two or more times to form a guide jaw 114 connected in an a-shaped shape. The guide jaw 114 is for preventing the slide hinge 130 from being separated from the rail hinge 110. When the slide hinge 130 is normally moved, the guide jaw 114 does not come into contact with the slide hinge 130. Spaced apart by a positive interval. In addition, the guide jaw 114 may also serve as a rib to reinforce the strength of the rail plate 112.

Then, a ring damper 129 is provided adjacent to the connection portion of the guide bar 126 and the rail plate 112. Damper 129 is to reduce the impact and noise caused by the direct contact between the slide hinge 130 and the rail hinge 110, it may have a variety of cross-sections, such as circular, square. The damper 129 may be formed of a resin and a structure having natural rubber or other buffering properties, such as conventional buffer rubber.

A binding groove 116 is provided at the upper and lower ends of the rail hinge portion 110, and a bottom of the upper finishing table 122 and the lower finishing table 124 is provided to accommodate the guide jaw 114 of the rail plate 112. Plate recess 128 is formed. In addition, a protrusion (not shown) for insertion into the binding groove 116 may protrude from the upper finishing table 122 and the lower finishing table 124, and the protrusion may be inserted into the binding groove 116 to be a rail plate 112. Can be fixed).

As shown in FIG. 5, the slide hinge 130 includes a slide guide 131 and a guide frame 142.

The slide guide 131 includes a through hole 134 penetrating the center portion of the slide guide 131 to slide along the guide bar 126. Accordingly, the guide bar 126 and the slide guide 131 are slidably moved while directly rubbing against each other. At this time, since the guide bar 126 and the slide guide 131 friction with each other, noise may occur during the sliding movement, and wear may occur on the friction surfaces of the guide bar 126 and the slide guide 131. However, in the present embodiment, the slide guide 131 may be manufactured using a polyacetal (POM) material. Polyacetal (POM) has excellent mechanical, thermal and chemical properties over a wide range of operating temperatures. In addition, polyacetal (POM) is remarkably superior to other resins such as creep resistance and fatigue resistance, and is suitable for use in the slide guide 131 because of its self-lubricating property. However, polyamide other than polyacetal and polyamide imide may be used as the lubricity material.

The slide guide 131 includes a guide body 132, a frame binding unit 136, and a guide protrusion 138. A through hole 134 is formed at the center of the guide body 132, and the guide bar 126 is inserted into the slide guide 131 through the through hole 134. The frame binding unit 136 is integrally formed inside the guide body 132, and a body hole 164 is formed in the frame binding unit 136 so that the screw may approach the guide frame 142. As shown, the rear surface of the frame binding portion 136 is formed inward from the rear surface of the guide body portion 132 with a predetermined step, and the guide frame 142 is mounted on the inwardly positioned frame binding portion 136. do. The step is formed to the thickness of the guide frame 142, it may be formed of a length of more or less. Therefore, the guide frame 142 does not protrude to the upper portion of the slide guide 131, the slide hinge 130 may have a thin thickness.

A free groove is formed in the center of the guide body 132, and a through hole 134 is formed in the guide body 132 around the free groove so that the guide bar 126 passes in the longitudinal direction. The upper portion of the clearance groove is open and the frame recess 133 is provided in the open space. Since the frame protrusion 144 protruding to both sides of the guide frame 142 is fixed to the frame recess 133, the guide frame 142 is stably fixed to the slide guide 131.

In response to the guide jaw 114 formed on the side of the rail plate 112, the guide protrusion 138 is formed on the side of the slide guide 131 facing the guide jaw 114. The guide protrusion 138 may be continuously formed along the longitudinal direction at the inner side of the frame binding unit 136, but the slide hinge 130 and the rail hinge 110 may be separated from each other even when the guide protrusion 138 is formed continuously. You can prevent it.

The guide frame 142 connects the slide guides 131 of both sides to each other, and the terminal body may be mounted on the rear surface of the guide frame 142. Since the guide frame 142 is fastened to the frame binding unit 136 having a step, the guide frame 142 does not protrude to the outside even after being fastened, and can be stably bound to an upper portion of the slide guide 131.

5, the torsion spring 150 is interposed between the rail hinge portion 110 and the slide hinge portion 130, and both ends thereof are rotatable with respect to the rail hinge portion 110 and the slide hinge portion 130, respectively. Connected. And, when fixed to the inner surface of the guide frame 142, it is rotatably connected by a spring rivet 146. In the present embodiment, the two springs are mounted at positions facing each other, but in some cases, only one torsion spring may be used. Since the torsion spring 150 provides repulsive forces opposite to each other based on one point of the movement path of the slide hinge 130, when the user moves the slide part by a predetermined working distance, the rail hinge 110 and The direction of the force by the torsion spring is automatically switched between the slide hinge 130 is designed to automatically move the remaining path.

Torsion spring 150 includes coil resilient portion 152 and two wire connections 154 and 156. The coil elastic portion 152 is a portion wound one or more times in the center of the torsion spring 150, the metal wire is formed into a spiral (spiral) to form a single layer. One wire connecting portion 154 extends from the center of the coil elastic portion 152 to bind together with the spring rivet 146 of the guide frame 142, and the other wire connecting portion 156 is the coil elastic portion 152. It extends from the outer side of and is rotatably bound to the rail plate 112. Here, the wire connecting portion 154 engaged with the spring rivet 146 has a circular end and is positioned to surround the rivet body 148.

The spring rivet 146 includes a rivet head 147 and a rivet body 148 to pivotally secure the ends of the wire connections 154 and to guide the ends to pivot within an angle within a range. . To this end, the rivet head 147 is spaced apart from the inner surface of the guide frame 142 by a predetermined interval, and the end of the wire connecting portion 154 pivots in the space between the rivet head 147 and the guide frame 142. Therefore, the up and down shaking of the torsion spring 150 in the slide hinge device according to the present invention can be minimized.

Referring to FIG. 6A, the torsion spring 150 has a flat top and bottom surfaces formed flat. In general, the width d of the torsion spring 150 is larger than the height h thereof, and may be formed by a drawing process.

FIG. 7 is a cross-sectional view illustrating a laminated structure of the torsion spring illustrated in FIG. 6A. As shown in FIG. 4, the wire structure of the torsion springs intersects almost vertically.

Referring to FIG. 7, since the cross section of the torsion spring 150 is flattened up and down, the height 2h in which the flat wire overlaps up and down can be made smaller than the conventional spring height. Since the elastic force of the torsion spring can be mainly determined by the width d of the wire, the height h can be further reduced while keeping the width d of the torsion spring almost the same as before. Moreover, since the wire which crosses up and down makes surface contact, smooth movement is possible.

In general, the spring of the stainless steel (SUS) material in the slide-type terminal can provide a suitable elastic force when the width of about 0.4 ~ 0.6mm, at this time to maintain the height of the spring of about 0.1 ~ 0.4mm It is possible.

Referring back to (b) and (c) of Figure 6, the cross section of the torsion spring may be formed in a quadrangle, only one of the upper surface and the bottom surface may be formed flat. In addition, the cross section of the torsion spring may be formed in a polygonal shape such as a hexagon, and the width and shape thereof may also be variously selected and changed.

After the damper 129 and the slide guide 131 are assembled to the guide bar 126, the assembly is disposed in the first mold 180. When the assembly is placed, the slide guide 131 is placed in the first receiving space 184, and both ends of the guide bar 126 are positioned to be partially received in the second receiving space 182 for forming the finish. . The upper finisher 122 and the lower finisher 124 may be molded in the second accommodation space 182.

Since the end of the guide bar 126 is partially accommodated in the upper finisher 122 and the lower finisher 124 through injection, it can be more firmly fixed by forming an unevenness at the end of the guide bar 126. Without having to assemble the upper finisher 122 and the lower finisher 124 by screwing, the finisher can be fixed to the guide bar 126 at a time. In the slide hinge device of the present embodiment, since the upper finishing table 122 and the lower finishing table 124 are injection molded to accommodate both ends of the guide bar 126, there is no burden of dimensional error, and the manufacturing process is convenient.

After the upper finisher 122, the lower finisher 124, and the guide bar 126 are integrally formed through injection molding, the rail plate 112 and the guide flame 142 are formed as shown in FIG. 5. Can be fastened to the finishing table 122, 124 and the slide guide 131, respectively. Rail plate 112 and the finish can be inserted and the projection of the finish in the binding groove 116 can be adjusted and fixed position. In addition, the guide frame 142 and the frame binding part 136 can be mutually fastened using a two-stage screw.
