To a hinge module.

In general, a communication terminal may be classified into a wired or wireless communication terminal, and a wired communication terminal is representative of an office or home telephone, and a mobile communication terminal is a typical example of a PCS, a cellular phone, or a PDA.

In addition, due to the development of the technology, the mobile terminal provides text information, image information, and the like to the user, beyond the step of delivering only simple voice information.

In addition, the types of mobile communication terminals are largely divided into a bar type, a flip type with a cover, a folder type, and a slide type.

A brief description will be given of a folder type among the various types of mobile communication terminals. The folder type mobile communication terminal is composed of a main body and a folder rotatably coupled to the main body, while the user opens and closes a folder according to a call or other needs. It is to be used.

However, in the conventional clamshell mobile communication terminal, since the opening angle of the folder opened through rotation from the main body is adapted to the call, the opening angle of the folder is suitable for use during the call during the use of the terminal, but the liquid crystal of the terminal is used. When using games such as playing a game or viewing images through the screen, there is a problem that the inconvenience is due to the opening angle of the folder that is opened in an inclined state relative to the main body.

In other words, for example, when the user enjoys a game through the LCD screen of the folder-type mobile communication terminal, the main body may also be in a predetermined inclined state in order to clearly stare at the LCD screen of the inclined open folder. Operation of the keypad becomes inconvenient. In addition, when the user views the image through the LCD screen of the folder-type mobile communication terminal, the position of the folder where the LCD screen can be clearly seen is very limited, so that the LCD screen cannot be clearly seen even if the user moves the terminal a little. This is brought about.

In recent years, a folder-type mobile communication terminal in which a folder is opened from the main body to an angle of 180 ° is provided. However, such a terminal has a problem in that it is inconvenient during a call.

The present invention has been made to solve the above problems, so that the open position from the main body of the folder rotatably connected to the main body can be selectively fixed at the opening angle and 180 ° opening angle for easy communication. It is an object of the present invention to provide a hinge module of a folder type mobile communication terminal.

In order to achieve the above object, the present invention provides a hinge module for rotatably connecting a center hinge arm and a side hinge arm, which are rotational connections between a main body and a folder of a clamshell mobile communication terminal, wherein the folder is connected to the center hinge arm. A housing inserted to rotate together during opening and closing, a fixed shaft supported at one end thereof while being supported by the side hinge arm while the other end thereof is supported by the side hinge arm, and a rotation preventing state while being rotated together with the housing inside the housing. A first rotating member installed on the fixed shaft for sliding movement, a second rotating member installed on the fixed shaft for rotating and sliding movement together with the first rotating member, and the first rotating member and the first rotating member installed on the fixed shaft. It is installed on the fixed shaft to allow the sliding movement of the rotation prevented state between the two rotating member, the closed state of the folder A stopper for stopping the first rotating member by stopping the first rotating member when rotating at a call angle of the folder at 0 °, and stopping the second rotating member when rotating the folder by 180 degrees; Provides a hinge module of a folding mobile communication terminal, characterized in that it comprises an elastic member which is installed to apply elasticity in the direction of the side hinge arm to the first and second rotating members and the stopper.

Prior to the description of the structure of the hinge module according to the present embodiment, as shown in FIG. 3, a foldable mobile communication terminal 100 to which the hinge module 1 of the present embodiment is applied is formed on both sides of the main body 110. The center hinge arm 140 of the folder 130 is inserted between the side hinge arm 120 of the rotation is connected to the example, the present invention is not limited to this between a pair of side hinge arms formed on both sides of the folder As the center hinge arm of the main body is inserted and rotated, it can be commonly applied to all hinge structures including the center hinge arm and the side hinge arm for rotational connection of the main body and the folder.

The housing 10 is rotatably coupled to the center hinge arm 140 so that one side is formed in an open shape so that the open side is directed toward the outside of the center hinge arm 140. In other words, the housing 10 is rotated together with the rotation of the center hinge arm 140 according to opening and closing of the folder 130. In addition, two opposite sides of the housing 10 form a parallel structure, and the inner surface of the center hinge arm 140 into which the housing 10 is inserted corresponds to the outer shape of the housing 10, thereby providing a housing ( 10 is preferably made to rotate together in the state inserted into the center hinge arm 140.

The fixed shaft 20 is supported in such a state that one end thereof is supported by the housing 10 and the other end thereof is prevented from rotating to the side hinge arm 120 of the main body 110. Here, the fixing part 22 having two sides parallel to the other end of the fixing shaft 20 is provided, and the inner surface of the side hinge arm 140 is made to correspond to such fixing part 22, the fixed shaft 20 is preferably supported while being prevented from rotating to the side hinge arm 140.

The first rotating member 30 is installed on the fixed shaft 30 to allow the sliding movement of the anti-rotation state along the fixed shaft 20 while being rotated together with the housing 10 inside the housing 10. The second rotating member 40 is installed on the fixed shaft 20 so that the second rotating member 40 may be rotated together when the first rotating member 30 is rotated at a position spaced apart from the first rotating member 30.

Here, a pair of arc-shaped protrusions 34 are formed symmetrically about the fixed shaft 20 on one surface facing the second rotating member 40 of the first rotating member 30 and the second rotating member 40. Since the cutting groove 44 for inserting the pair of arc protrusions 34 into () is formed, the rotational force of the arc-shaped protrusions 34 is the first rotation member 30 and the second rotation member 40. It is desirable to be rotated together while being transmitted to the inner surface of the).

The stopper 50 is installed on the fixed shaft 20 to allow the sliding movement of the rotation prevented state between the first rotating member 30 and the second rotating member 40. Then, the stopper 50 stops the first rotating member 30 at the opening of the folder 130 at an angle at the time of the call of the folder 130 by setting the closed state of the folder 130 to 0 °. The first rotating member 40 is secondarily stopped at 180 ° opening of the 130.

Here, as the concave-convex portions 32 and 52 having inclined concave-convex portions for stopping the folder 130 in the 180 ° open state are formed on opposite surfaces of the stopper 50 and the first rotating member 30, respectively. When the folder 130 rotates at an opening angle of 180 °, the uneven portion 52 of the stopper 50 is engaged with the uneven portion 32 of the first rotating member 30 by the elastic force of the elastic member 60 which will be described later. Rotation of the first rotating member 30 is prevented. Accordingly, while the housing 10 interlocking with the first rotating member 30 and the center hinge arm 140 interlocking with the housing 10 are prevented from rotating, the folder 130 is stopped at an opening angle of 180 °.

In addition, a stop protrusion 54 is formed on one surface of the stopper 50 facing the second rotating member 40 to stop the folder 130 at an opening angle during a call. Since the stop groove 42 is formed to support the stop projection 54 on the inner surface at the opening angle during the call of the folder 130, the folder 130 is formed of the elastic member 60 which will be described later when rotating to the open state during the call. The stop protrusion 54 of the stopper 50 is inserted into the stop groove 42 of the second rotating member 40 by the elastic force, thereby preventing the rotation of the second rotating member 40, and at the same time, the second rotating member 40. Rotation of the first rotating member 30 interlocked with is prevented. Accordingly, while the housing 10 interlocking with the first rotating member 30 and the center hinge arm 140 interlocking with the housing 10 are prevented from rotating, the folder 130 is stopped at an opening angle during a call. Here, the opening angle during the call of the folder 130 is preferably 150 degrees.

The elastic member 60 is installed to apply elasticity in the direction of the side hinge arm 120 of the main body 110 to the first and second rotating members 30 and 40 and the stopper 50. Such an elastic member 60 is preferably a configuration of a compression spring installed on the fixed shaft 20 while supporting both ends on the inner surface of the housing 10 and one surface of the second rotating member 40.

In addition, the housing 10 is provided on the two surfaces of the fixing part 22 and the first rotating member 30 which are provided in the fixed shaft 20 and inserted into the side hinge arm 120 of the main body 110 to prevent rotation. It is preferable that the uneven parts 24 and 36 each having an inclined unevenness for sliding the first rotating member 30 to the inside of the housing 10 during the rotation of the). In other words, when the folder 130 rotates, the uneven portion 36 of the first rotating member 30 rotated together with the center hinge arm 140 and the housing 10 may be fixed to the fixed portion 22 of the fixed shaft 20. The first rotating member 30 is slidably moved inwardly of the housing 10 while being pushed by the formed uneven portion 24. In addition, when the folder 130 is closed, the uneven part 24 of the fixing part 22 and the uneven part 36 of the first rotating member 30 are engaged with each other by the elasticity of the elastic member 60. 30) is restored to the original watch.

By the above configuration, a brief description will be made of an operation in which the rotation of the folder is stopped at 150 ° and 180 °, respectively, when the folder is opened and closed in the folder type mobile communication terminal.

First, as described above, it is assumed that the rotation angle of the folder 130 is 0 ° in the state in which the folder 130 is closed by the main body 110.

Rotating member 30 is also rotated together. In addition, when the folder 130 is opened at a rotation angle of 150 °, the center hinge arm 140, the housing 10, and the first rotating member 30 are also at an angle of 150 ° from the first 0 ° when the folder 130 is closed. When the first rotary member 30 is rotated at an angle of 150 °, the second rotary member 40 is also rotated at an angle of 150 ° while the stop groove 42 of the stop groove 42 and the stopper 50 are parallel to each other. The stop protrusion 54 is fitted into the stop groove 42 by the elasticity of the elastic member 60 when positioned.

FIG. 6 is a view illustrating an example in which the stop protrusion 54 of the stopper 50 is inserted into the stop groove 42 of the second rotating member 40, and thus, of the second rotating member 40. While the rotation is prevented, the rotation of the first rotation member 30 interlocked with the rotation is prevented, and the rotation-prevented first rotation member 30 prevents the rotation of the housing 10 and the center hinge arm 140. Rotation of the folder 130 is stopped at an opening angle of 150 °. 7 is a cross-sectional view illustrating a contact state between the first rotating member 30 and each of the uneven parts 32 and 52 of the stopper 50 in a state where the rotation of the folder 130 forms an opening angle of 150 °. to be.

When the folder 130 is artificially further opened while the opening of the folder 130 is stopped at 150 ° as described above, the stop protrusion 54 of the stopper 50 stops the second rotating member 40. Rotation of the folder 130 continues while exiting the groove 42.

When the folder 130 is rotated again as described above, the center hinge arm 140 and the housing 10 and the first rotating member 30 are also rotated at an angle of 180 ° when the folder 130 is opened at a 180 ° rotation angle. The uneven part 32 of the first rotating member 30 and the uneven part of the stopper 52 coincide with each other by the elastic force of the elastic member 60 when opening at a 180 ° rotation angle of the two uneven parts 32 and 52. Are interlocked with each other.

FIG. 8 is a diagram illustrating a state in which the uneven parts 32 and 52 of the first rotating member 30 and the stopper 50 are engaged with each other, thus rotating the first rotating member 30. While being prevented, the first rotation member 30 prevents the rotation of the housing 10 and the center hinge arm 140 so that the rotation of the folder 130 is stopped at an opening angle of 180 °. 7 illustrates a state of contact between the stop groove 42 of the second rotating member 40 and the stop protrusion 54 of the stopper 50 in a state where the rotation of the folder 130 forms an opening angle of 180 °. The figure shown.

As can be seen through the above embodiment, the hinge module of the clamshell mobile communication terminal according to the present invention, in the course of using a clamshell mobile communication terminal, opening a folder of 150 ° suitable for a call during a call Maintaining the angle, and in the case of playing a game or viewing an image, the folder can be used by maintaining the opening angle of 180 °, so that the convenience and functionality of the terminal can be greatly improved.

In addition, since the process of stopping the folder at an angle suitable for a call or stopping at an opening angle of 180 ° is naturally performed during the opening and closing of the folder, it is very easy to switch the folder between the call angle and the 180 ° opening angle. Can be done.
