Description

Actuator

The present invention relates to an actuator, and more particularly, to an actuator interposed between a first slide hinge portion and a second slide hinge portion that slides with each other to provide an elastic force required for slide movement.

In general, personal handheld terminals have been widely used as conveniences that anyone can easily carry and use freely anywhere.

Such personal handheld terminals have begun to be used for wireless voice communication, but as their functional areas are gradually diversified, they are being developed to have various additional functions such as games and basic voice communication functions.

Such personal portable terminals can be generally classified into a bar-type personal portable terminal, a folder-type personal portable terminal, a slide-type personal portable terminal, and the like according to their appearance or operation method.

Among these, the slide type personal portable terminal refers to a personal portable terminal in which a slide part disposed to overlap each other with the main body part is slidably opened and closed with respect to the main body part.

Meanwhile, an actuator for providing an elastic force may be used in the slide type personal portable terminal, and the actuator may provide an elastic force so that the slide movement of the slide portion with respect to the main body portion can be implemented semi-automatically or automatically.

As a general actuator, a torsion spring including a coil elastic part may be used, and one end of the torsion spring is connected to the main body part and the other end is connected to the slide part (or the main body part and the slide part via a conventional slide hinge unit, respectively). Connected) so that the slide movement of the slide portion relative to the body portion can be made elastic.

However, the conventional torsion spring has a problem in that it is difficult to slim down because there is a limit in reducing the thickness due to its structural characteristics. That is, as the torsion spring is disposed so that the coil elastic part and the wire part overlap each other, the thickness of the spring increases as the coil elastic part and the wire part overlap each other, so there is a limit in reducing the thickness, making it difficult to slim down.

In addition, the conventional torsion spring has a problem in that friction and noise are caused by mutual interference between the coil elastic part and the wire part, and the sliding feeling of the slide part is lowered. In addition, the conventional torsion spring is difficult to improve the elastic force by a certain or more, there is a problem that the elastic force is lowered by the fatigue stress when used repeatedly for a long time.

Accordingly, in recent years, various studies have been made on actuators that can contribute to slimming and can improve stability and reliability.

The present invention provides an actuator capable of improving operational stability and reliability.

In addition, the present invention provides an actuator that can increase the elastic force and can extend the life.

In addition, the present invention provides an actuator that can simplify the structure and manufacturing process, reduce the cost and improve the productivity.

In addition, the present invention provides an actuator capable of minimizing the space required for mounting and operating the actuator and improving the space utilization and design freedom of the object to which the actuator is mounted.

According to a preferred embodiment of the present invention for achieving the above object of the present invention, the actuator interposed between the first slide hinge portion and the second slide hinge which slides with each other, partially removes a part of the thin metal plate And at least one spring plate, wherein the spring plate includes: a first plate holder portion pivotally coupled to the first slide hinge portion and a second plate holder pivotally coupled to the second slide hinge portion; And a connecting portion having a plurality of plate ribs integrally connected to the first plate holder portion and the second plate holder portion and spaced apart on the same plane, wherein the plurality of plate ribs are formed to have different lengths. Are arranged in order, and have a relatively long length to have a progressively larger width. Is formed.

For reference, the first slide hinge portion and the second slide hinge portion in the present invention may be understood as a housing (or case) itself of the main body portion and the slide portion that are slidably coupled to each other in a conventional slide type personal portable terminal. May be understood as various sliding elements that are manufactured and coupled separately from the main body and the slide to implement sliding of the slide with respect to the main body.

The spring plate consists of a metal plate having a very thin thickness and is provided to have the same thickness as a whole. The spring plate may be formed by partially removing a portion of a conventional thin metal plate having excellent hardness. For example, the thin metal plate may be formed of various metal materials such as copper, copper alloy, stainless steel, aluminum, titanium, platinum, nickel, and the like, but the present invention is not limited or limited by the type and characteristics of the metal plate.

As a processing method for partially removing a portion of the thin metal plate to form a spring plate, various methods may be employed depending on the required conditions and design specifications.

The plate ribs are formed to have different lengths and are arranged in the order of length. The plate ribs are formed to have a progressively larger width as they have a relatively long length. Such a structure allows even elastic force to be generated across all plate ribs. That is, in the case of plate ribs having a relatively long length, the restoring force due to elastic deformation is smaller than that of plate ribs having a relatively short length, so that the plate ribs have a relatively long length, the elastic force generated during elastic deformation becomes smaller. . However, in the present invention, the plate ribs having a relatively long length can be made larger in width so that the difference in elastic force according to the difference in length of each plate rib can be compensated. As such, even though each plate rib has a different length, all plate ribs may provide the same elastic force because each plate rib has a different width. In other words, it can be understood that all the plate ribs provide the same elastic force, respectively, so that the stress can be evenly distributed over all the plate ribs, which in turn ensures stable operation and extends the life of the product. do.

As shown in FIG. 1, the slide type personal portable terminal to which the slide hinge device according to the present invention is applied includes a first slide hinge portion, a second slide hinge portion, and an actuator.

For reference, the first slide hinge portion and the second slide hinge portion in the present invention may be understood as a housing (or case) itself of the main body portion and the slide portion that are slidably coupled to each other in a conventional slide type personal portable terminal. May be understood as various sliding elements (eg, various plates, frames, guide bars, etc.) that are separately manufactured and coupled with the main body and the slide to implement sliding of the slide with respect to the main body.

Hereinafter, a sliding element that is separately coupled to the main body portion 10 and the slide portion 20 will be described with an example configured to form the first slide hinge portion and the second slide hinge portion. That is, a rail plate (second slide hinge portion) (not shown) may be mounted on the rear surface of the slide portion 20 facing the main body portion 10, and the main body portion 10 facing the slide portion 20. A guide frame (first slide hinge portion) 110 may be mounted on a front surface of the rail plate to partially accommodate both side ends of the rail plate and to be slidably coupled along a length direction of the rail plate.

In some cases, the guide bar may be provided on the rear surface of the slide unit, and the guide frame provided on the main body unit may be configured to slide along the guide bar. As described above, the sliding structure between the first slide hinge portion and the second slide hinge portion may be variously changed according to required conditions and design specifications, and the present invention may be implemented by a sliding coupling method of the first slide hinge portion and the second slide hinge portion. This is not limited or limited.

The actuator according to the present invention may be mounted on a slide type portable portable terminal including a first slide hinge portion and a second slide hinge portion that are slidably coupled to each other, and specifically, the first slide hinge portion and the second slide hinge portion. It can be intervened in between. Such an actuator provides an elastic force between the first slide hinge portion and the second slide hinge portion, and the driving force moves automatically when the user manually pushes up (or pushes down) the slide portion 20 by a predetermined distance. Can be provided.

2 to 3, the actuator according to the present invention includes at least one spring plate 100 formed by partially removing a portion of the thin metal plate, wherein the spring plate is the first plate holder part 110. ), The second plate holder portion 120 and the connecting portion 130.

The spring plate 100 is made of a metal plate having a very thin thickness and is provided to have the same thickness as a whole. The spring plate 100 may be formed by partially removing a portion of a conventional thin metal plate having excellent hardness. For example, the thin metal plate may be formed of various metal materials such as copper, copper alloy, stainless steel, aluminum, titanium, platinum, nickel, and the like, but the present invention is not limited or limited by the type and characteristics of the metal plate. . Since the metal plate is superior in hardness to general plastics, even when made very thin, it may have a hard form, that is, excellent shape strength. Hereinafter, the spring plate 100 will be described with an example formed using a thin metal plate having a thickness of 0.4 mm.

The spring plate 100 processes the above-described thin metal plate to partially remove the metal plate, whereby the first plate holder part 110, the second plate holder part 120, and a plurality of plate ribs ( It may be provided in a predetermined form including a connecting portion 130 having a 130a ~ 130j. As a processing method for partially removing a portion of the thin metal plate to form the spring plate 100, various methods may be employed according to required conditions and design specifications. Hereinafter, the spring plate 100 will be described with an example formed by partially removing a portion of the thin metal plate by a normal etching process.

On the other hand, in some cases, the spring plate may be formed by partially removing a portion of the thin metal plate by conventional press working or wire working, which is relatively simple in manufacturing. However, when the spring plate is formed by press or wire processing, it may be locally concentrated in the spring plate, thereby lowering reliability and lowering elastic properties of the spring plate. In addition, by press and wire processing, there is a problem in that it is very difficult to realize a fine spacing between the plate ribs more than a certain amount, and it is difficult to increase the number of plate ribs more than a certain amount. However, in the exemplary embodiment of the present invention, since the spring plate may be formed by partially removing a portion of the thin metal plate by an etching process, there is a concern about deformation and flatness during processing, and the size and spacing of the plate ribs. Plate ribs can be easily formed without limiting the spacing.

Preferably, the spring plate 100 may be formed by a double-sided etching process. That is, the spring plate may be formed by etching only one surface of both surfaces, but since the etching may occur to the peripheral portion of the etching portion required by the nature of the etching process, the spring plate may be minimized. 100) is preferably formed by partially removing one surface specific portion of the thin metal plate and the other surface specific portion of the thin metal plate corresponding to the one surface specific portion by a double-sided etching process.

The first plate holder part 110 and the second plate holder part 120 constituting the spring plate 100 are disposed to face each other, and one of the

plate holder parts

110 and 120 pivots on the first slide hinge part. pivotally bound, the other of each plate holder portion pivotally bound to the second slide hinge portion. Hereinafter, an example in which the first plate holder part 110 is bound to the first slide hinge part and the second plate holder part 120 is bound to the second slide hinge part will be described.

In addition, the first plate holder part 110 and the second plate holder part 120 may be provided with a pivot coupling hole (111, 121) to be pivotally coupled to the target object, such as a slide hinge, Hereinafter, the pivot coupling holes 111 and 121 will be described with an example provided in the form having the

entrance openings

111a and 121a opened at one side of the side. Therefore, the first pivot coupling hole 111 and the second pivot coupling hole 121 formed in each of the

plate holder parts

110 and 120 may be pivotally coupled to a corresponding object through a conventional pivot member. That is, each of the pivot coupling holes 111 and 121 of the first plate holder part 110 and the second plate holder part 120 has a coupling hole (not shown) formed in the slide hinge portion corresponding to the conventional pivot member. It can be pivotally coupled.

Here, the pivot member may be understood as a kind of shaft means, and the present invention is not limited or limited by the type and characteristics of the pivot member. As one example, a conventional rivet, pin, piece, or the like may be used as the pivot member.

The connecting portion 130 is a plate rib that integrally connects the first plate holder 110 and the second plate holder 120 between the first plate holder 110 and the second plate holder 120. It comprises a (130a ~ 130j). In addition, the plurality of plate ribs 130a to 130j may be provided in parallel to be spaced apart from each other at a predetermined interval in the same plane, and the number and spacing interval of the plate ribs 130a to 130j are required conditions and design specifications. It can be changed in various ways.

Hereinafter, ten plate ribs 130a to 130j are formed to be spaced apart from each other at uniform intervals, and each plate rib 130a to 130j is formed to have a different length and is arranged in the order of length. 130a to 130j) will be described with an example formed to have a progressively larger width as it has a relatively long length.

That is, the ten plate ribs 130a to 130j are disposed in order of length so as to have a gradually smaller length from top to bottom, and the widths W1 to W10 of the ten plate ribs 130a to 130j have relatively long lengths. The more you have, the bigger it gets. For example, the plate ribs 130a disposed at the lowermost end corresponding to the inner side adjacent to the center between the first and second

plate holder parts

110 and 120 among the ten plate ribs 130a to 130j may be bent to have a predetermined arc. The plate ribs 130b to 130j sequentially formed thereon may be formed to have a length that gradually increases toward the outside (that is, length of 130a <length of 130b <length of 130c <.... <length of 130j Can be formed. At this time, the plate ribs 130a disposed at the lowermost end of the ten plate ribs 130a to 130j may be formed to have a predetermined width W1, and the plate ribs 130b to 130j sequentially formed thereon are outward. It may be formed so as to gradually have a larger width (that is, W1 <W2 <W3 <.... <W10).

As such, the plate ribs 130a to 130j are formed to have a progressively larger width as they have a relatively long length. Such a structure allows elastic force to be generated evenly over all the plate ribs 130a to 130j. do.

That is, in the case of plate ribs having a relatively long length (for example, 130j), plate ribs 130a to 130j have relatively low restoring force due to elastic deformation compared to plate ribs having a relatively short length (for example, 130a). The relatively longer the length, the smaller the elastic force generated during elastic deformation. However, in the present invention, the width of the plate rib having a relatively long length can be increased, so that the difference in elastic force according to the difference in length of each plate rib 130a to 130j can be compensated. As described above, even though each of the plate ribs 130a to 130j has a different length, all the plate ribs 130a to 130j may provide the same elastic force because the plate ribs 130a to 130j have different widths. . In other words, it can be understood that all the plate ribs 130a to 130j provide the same elastic force, respectively, so that the stress can be evenly distributed over all the plate ribs 130a to 130j, which in turn ensures stable operation. At the same time, it can extend the life of the product.

Meanwhile, in the above-described and illustrated embodiments of the present invention, although the spring plate 100 includes ten plate ribs 130a to 130j, the spring plate 100 is described as an example. It may also comprise less than 10 or more than 11 plate ribs.

In the above description, although the first plate holder part 110, the second plate holder part 120, and the connection part 130 are described as independent components, respectively, the first plate holder part 110 is substantially the same. ), The second plate holder portion 120 and the connecting portion 130 is provided as a single body (single body) connected integrally by processing one metal plate.

In addition, the spring plate according to the present invention may be surface treated for stabilization of the shape and equalization of the surface. For example, the surface of the spring plate may be surface treated by methods such as polishing, painting, deposition, coating, and the like. The surface treatment process order of the spring plate may be appropriately changed according to the required conditions and design specifications, and the present invention is not limited or limited by the surface treatment method and characteristics. In addition, the spring plate according to the present invention may be annealed by a heat treatment process to improve the hardness and extend the life.

On the other hand, Figure 4 is a view for explaining the structure and operating state of the actuator according to another embodiment of the present invention. In addition, the same or equivalent reference numerals are given to the same or equivalent components as those described above, and detailed description thereof will be omitted.

As shown in FIG. 4, the actuator according to another embodiment of the present invention includes at least one spring plate 200 formed by partially removing a portion of the thin metal plate, wherein the spring plate 200 includes a first slide. A first plate holder portion 210 pivotally coupled to a hinge portion, a second plate holder portion 220 pivotally coupled to the second slide hinge portion, and the first plate holder portion And a connecting portion 230 having a plurality of plate ribs 230a to 230i integrally connecting the 210 and the second plate holder portion 220 to each other, wherein the plurality of plate ribs 230a to 230i have different lengths. It is formed so as to be arranged in the order of length, and having a relatively long length is formed to have a progressively larger width and the spacing interval between the plurality of plate ribs (230a ~ 230i) is a relatively long length The take is configured so as to increase gradually.

Hereinafter, nine plate ribs 230a to 230i formed to have different lengths are arranged in order of length, and the nine plate ribs 230a to 230i are formed to have a larger width gradually as they have a relatively long length. The spacing interval L1 to L8 between the plate ribs 230a to 230i will be described by way of example, which is configured to gradually become larger as it has a relatively long length.

That is, the plate ribs 230a disposed at the lowermost end of the nine plate ribs 230a to 230i may be formed to have a predetermined width, and plate ribs 230b to 230i sequentially formed thereon are gradually larger toward the outside. It may be formed to have a width. Further, the spacing between the nine plate ribs 230a to 230i is gradually increased from the inner side to the outer side adjacent to the center between the first and second plate holder portions 210 and 220 (that is, L1 <L2 <L3 <. .. <L8) can be formed.

As described above, the plate ribs 230a to 230i are formed to have a relatively long length so that the separation interval is gradually increased. Such a structure does not interfere with each other when the plate ribs 230a to 230i are elastically deformed. It can be flowed stably without.

That is, in the case of plate ribs having a relatively long length (for example, 230i), the plate ribs having a relatively long length during elastic deformation are larger than the plate ribs having a relatively short length (for example, 230a). And interference between the plate ribs having a relatively short length (in particular, at the center of the plate ribs) may occur.

However, in the present invention, the spacing interval (L1 ~ L8) between the plate ribs (230a ~ 230i) is gradually increased as having a relatively long length, even if each plate rib (230a ~ 230i) has a different amount of elastic deformation Mutual interference between the plate ribs 230a to 230i may be prevented. Therefore, it is possible to ensure the stable operation of the product as well as to extend the life of the product.

In addition, the same or equivalent reference numerals are given to the same or equivalent components as those described above, and detailed description thereof will be omitted.

In the above-described and illustrated embodiments of the present invention, each of the plate ribs of the spring plate is simply described as an example of a curved curve, but in some cases, a plurality of plate ribs may be used to disperse the stress concentration during operation of the actuator. At least one of the may include a bent portion bent at least once on a single layer.

That is, referring to FIGS. 5 and 6, the actuator according to another embodiment of the present invention includes at least one spring plate 300 formed by partially removing a portion of the thin metal plate, wherein the spring plate ( 300 is a first plate holder portion 310 pivotally coupled to a first slide hinge portion, a second plate holder portion 320 pivotally coupled to a second slide hinge portion, and It includes a connecting portion 330 having a plurality of plate ribs (330a ~ 330h) for integrally connecting the first plate holder portion 310 and the second plate holder portion 320, a plurality of plate ribs (330a ~ 330h) ) Are formed to have different lengths and are arranged in order of length, and have a relatively long length and have a progressively larger width, and the plurality of plate ribs 330a to 330h are formed on at least one layer.
